BACKGROUND

An electronic atomizing device with variety of flavors in related art usually includes a suction nozzle assembly and an atomizing assembly.

DETAILED DESCRIPTION

The technical solutions in some embodiments of the present disclosure may be clearly and completely described in conjunction with accompanying drawings in some embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, and not all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of the present disclosure.

The purpose of the present disclosure is to provide a suction nozzle assembly, an electronic atomizing device, and an assembly method of the electronic atomizing device. By improving the structure of the suction nozzle assembly, the problem of condensate liquid accumulation caused by the suction nozzle assembly in related art can be solved.

As illustrated in FIGS. 1-2, a first embodiment of the present disclosure provides an electronic atomizing device 1000. The electronic atomizing device 1000 can be a sliding electronic atomizing device. The electronic atomizing device 1000 includes a suction nozzle assembly 100, an atomizing assembly 200, and a tail cover assembly 300 in sequence from top to bottom. The bottom of the suction nozzle assembly 100 is connected to a shell 400 through connection manners, such as adhesive bonding, tight fitting, clamping, or welding, etc. The atomizing assembly 200 and the tail cover assembly 300 are disposed inside the shell 400, and the atomizing assembly 200 is installed on the tail cover assembly 300. The suction nozzle assembly 100 is disposed above the atomizing assembly 200 and installed on the top of the shell 400. The suction nozzle assembly 100 includes a suction nozzle 11 and two injecting holes 12 disposed on two opposite sides of the suction nozzle 11. That is, one of the two injecting holes 12 is disposed on one side of the suction nozzle 11, and the other of the two injecting holes 12 is disposed on the other side of the suction nozzle 11. Each injecting hole 2 is provided with a liquid plug 500. The two injecting holes 12 can be symmetrically disposed.

As illustrated in FIGS. 2-3, in some embodiments, the suction nozzle assembly 100 includes a suction nozzle unit 102, a sliding unit 14, and a support cover 15. The suction nozzle unit 102 defines an exhaust hole 110. The suction nozzle unit 102 can be sucked by a user's mouth, and the exhaust hole 110 is configured to discharge gas delivered by the suction nozzle assembly 100 into the user's mouth. The sliding unit 14 can be fixedly connected to the suction nozzle unit 102 through connection manners, such as screw coupling, adhesive bonding, snap coupling, tight fitting, etc. The bottom of the sliding unit 14 defines a gas inlet, and a gas flow channel is defined inside the sliding unit 14. The gas inlet, the gas flow channel, and the exhaust hole 110 are sequentially communicated. The sliding unit 14 is at least partly accommodated in the support cover 15, and the suction nozzle unit 102 is supported by the support cover 15. The suction nozzle unit 102 is configured to drive the sliding unit 14 to slide in the support cover 15.

The inventors of the present application have found that in the electronic atomizing device of the related art, during the movement of the suction nozzle assembly relative to the atomizing assembly, the suction nozzle assembly will squeeze elements of the atomizing assembly, and the elements of the atomizing assembly are in contact with the suction nozzle assembly. Thus, the condensate liquid on the elements is pushed and accumulated together, and the aggregation of the condensate liquid will have adverse effects.

In the suction nozzle assembly 100 in some embodiments of the present disclosure, the suction nozzle unit 102 is supported on the support cover 15 and configured for sliding. During a sliding process, due to support and limit of the support cover 15, the sliding unit 14 is disposed to slide in the support cover 15. Thus, direct downward compression of a component (such as the atomizing assembly 200) that is in sliding contact with the sliding unit 14 can be prevented. It avoids the sliding unit 14 from directly compressing the component that is in sliding contact with the sliding unit 14 by an external force, reducing the impact on the component during the sliding process, thereby reducing or eliminating the accumulation of the condensate liquid.

The above suction nozzle assembly 100 can be applied to an electronic atomizing device 1000, such as an electronic cigarette. In some embodiments, the above suction nozzle assembly 100 can also be applied to other gas supply devices that provide flowing gas. For example, the gas supply device can provide a gas or aerosol with a temperature higher than or equal to an ambient temperature, so that the exhaust state (such as composition of the exhaust gas, or volume of flow of the exhaust gas, etc.) is switched by sliding the sliding unit 14 of the suction nozzle assembly 100. In fact, as long as there is gas flow, the temperature of the gas flow itself will decrease, which may lead to condensation. However, this condensation phenomenon is more pronounced in response to the gas or aerosol being greater than the ambient temperature. Thus, the suction nozzle assembly 100 in some embodiments of the present disclosure can solve the problem that condensation is prone to occur during the sliding process.

In some embodiments, the suction nozzle unit 102 includes a bottom surface, and the exhaust hole 110 extends away from the bottom surface. The bottom surface can be a surface of the suction nozzle unit 102 facing the support cover 15, and can be disposed in a flat or curved shape. The suction nozzle unit 102 is located above the support cover 15 and supported by the support cover 15, and the bottom surface is also supported by the support cover 15. In this way, it is convenient to design structures of the suction nozzle unit 102 and the support cover 15, so that after the suction nozzle unit 102 is connected to the sliding unit 14, the bottom surface of the suction nozzle unit 102 is in sliding contact with the support cover 15.

In some embodiments, the sliding unit 14 can be supported by the support cover 15, and the suction nozzle unit 102 is configured to drive the sliding unit 14 to slide in the support cover 15. A sliding part (not shown in the figures) is disposed on a side wall of the sliding unit 14, and a sliding groove (not shown in the figures) is defined on a side wall of the support cover 15 corresponding to the sliding part. The support cover 15 is configured to have a certain degree of elasticity, such as being made of plastic or metal. In assembly process, during inserting the sliding unit 14 into the support cover 15, the sliding part can press the side wall of the support cover 15 outward until the sliding part enters the sliding groove and the side wall returns to its original shape. Thus, the sliding part can slide inside the sliding groove, and at the same time, the sliding groove generates upward support force for the sliding part, thereby providing upward support for the entirety of the suction nozzle unit 102 and sliding unit 14 that are fixed together. In this way, the support cover 15 can also support the entire suction nozzle unit 102. Moreover, as both the sliding part and the sliding groove are protected by the support cover 15, it is beneficial to reduce wear caused by the entry of external pollutants.

As illustrated in FIGS. 2-3, in some embodiments, the suction nozzle assembly 100 includes, from top to bottom, the suction nozzle 11, a suction nozzle upper bracket 13, the sliding unit 14, and a support cover 15. The sliding unit 14 can be supported by the support cover 15 and driven by the suction nozzle upper bracket 13 to slide in the support cover 15. The top of the suction nozzle upper bracket 13 is sleeved with the suction nozzle 11 for supporting the suction nozzle 11. The sliding unit 14 is sleeved with the bottom of the suction nozzle upper bracket 13. A gas flow through-hole is defined in the middle of the top of the suction nozzle upper bracket 13. The installation holes are defined on two opposite sides of the gas flow through-hole, and the installation holes can be screw holes or cylindrical holes. The top of the sliding unit 14 defines a central through-hole corresponding to the gas flow through-hole, the openings are defined on two opposite sides of the central through-hole and correspond to the installation holes, and the openings can be screw holes or cylindrical holes. The top of the support cover 15 defines an installation hole for the sliding unit 14 to pass through. The suction nozzle upper bracket 13 can drive the sliding unit 14 to slide in the installation hole of the support cover 15. The injecting hole 12 is defined on the surface of the support cover 15. The installation hole here is a backup fixed structure, which is convenient for fixing the suction nozzle upper bracket 13 and sliding unit 14 with the screws. Those of ordinary skill in the art can also achieve a fixed connection between the suction nozzle upper bracket 13 and sliding unit 14 through other connection manners, such as adhesive bonding, snap coupling, and tight fitting. The bottom surface of the suction nozzle unit 102 can include the bottom surface of the suction nozzle 11 or the bottom surface of the suction nozzle upper bracket 13. In some embodiments, the bottom surface of the suction nozzle unit 102 can include the bottom surface of the suction nozzle 11 and the bottom surface of the suction nozzle upper bracket 13.

In some embodiments, the atomizing assembly 200 is configured to provide a plurality of aerosols, wherein the atomizing assembly defines a plurality of gas outlets configured to output the plurality of aerosols respectively. The atomizing assembly 200 includes, from top to bottom, a suction nozzle cover 21, a liquid cup 22, and a liquid cup cover 24. The liquid cup 22 includes two independent liquid chambers, and the bottom of the liquid chamber is provided with an atomization core installing base 220. A ceramic atomizing core 23 is sleeved with an atomizing core sleeve and installed in the atomization core installing base 220. The suction nozzle cover 21 defines two or more gas outlets. The suction nozzle cover 21 is disposed on the bottom of the support cover 15. The suction nozzle cover 21 is installed on the top of the liquid cup 22. The liquid cup cap 24 is disposed below the liquid cup 22 to seal the bottom of the liquid cup 22. The atomizing assembly 200 further includes an elastic member 25. In some embodiments, the elastic member 25 is a spring top needle or other rod-shaped elastic members with longitudinal elasticity. The top of the elastic member 25 is hemispherical or other smooth curved surfaces. The top of the elastic member 25 extends from the surface of the suction nozzle cover 21 in response to the elastic member 25 being not under a pressure, and top of the elastic member 25 contracts downward in response to the elastic member 25 being under the pressure.

In some embodiments, the tail cover assembly 300 includes a tail cover bracket 31, a control board 32, and a battery cell 33. The top of the tail cover bracket 31 is configured to install the atomizing assembly 200. The tail cover bracket 31 can form an interference fit structure with the liquid cup cover 24. The control board 32 and the battery cell 33 are installed inside the tail cover bracket 31. The control board 32 is provided with a gas flow induction switch 34 and a button 35. The gas flow induction switch 34 is sleeved with a switch sleeve 36, and the button 35 is sleeved with a patch 37.

As illustrated in FIGS. 2 and 4-5, in some embodiments, the sliding unit 14 includes a suction nozzle lower bracket 141, a suction nozzle plug 142, a liquid absorbing member 143, and a suction nozzle cover plate 144. The liquid absorbing member 143 can be a liquid absorbing cotton, a liquid absorbing sponge, etc. The suction nozzle lower bracket 141 is configured to connect and fix the suction nozzle upper bracket 13 and the suction nozzle cover plate 144. The suction nozzle lower bracket 141 can be integrated and can include a bracket top, a bracket middle connecting part, and a bracket bottom. The bracket bottom defines a receiving cavity with a downward opening, and the bracket middle connecting part and the bracket top define a hollow communicating cavity. The communicating cavity is communicated with the receiving cavity. The bracket top is fixedly connected to the suction nozzle upper bracket 13, and the bracket bottom is fixedly connected to the suction nozzle cover plate 144. The bracket bottom is disposed in the support cover 15. The bracket top extends from the installation hole defined on the top of the support cover 15, so that the bracket top is disposed above the support cover 15. The suction nozzle plug 142 is made of material, the suction nozzle plug 142 is installed in the communicating cavity and the receiving cavity of the suction nozzle lower bracket 141 and defines a plug channel, and the gas flow channel includes the plug channel. The top of the suction nozzle plug 142 protrudes from the bracket top, and the suction nozzle plug 142 is configured to seal the suction nozzle upper bracket 13 and the suction nozzle lower bracket 141.

In some embodiments, the bottom surface of the suction nozzle unit 102 can include a sliding strip 131, and an extension direction of the sliding strip 131 is parallel to a sliding direction. In the assembled structure, the bottom surface of the suction nozzle unit 102 faces the upper surface of the support cover 15, and the sliding strip 131 is in direct contact with and can slide on the upper surface of the support cover 15. The design of sliding strip 131 is beneficial for reducing sliding friction, enhancing the durability of the sliding structure, and improving the performance of the sliding structure.

In some embodiments, the bottom of the suction nozzle upper bracket 13 is provided with two parallel sliding strips 131 on two bottom edges parallel to the sliding direction, and the extension directions of the sliding strips 131 are parallel to the sliding direction. The suction nozzle plug 142 is disposed in each of cavities that are defined in the center of the suction nozzle lower bracket 141 and the center of the suction nozzle cover plate 144, configured to guide the gas flow of the suction nozzle 11, so that the gas output from the suction nozzle cover plate 144 is transported to the suction nozzle 11 by the suction nozzle plug 142. The liquid absorbing member 143 is disposed between the suction nozzle plug 142 and the suction nozzle cover plate 144. The suction nozzle 11 is connected to the suction nozzle upper bracket 13 through a buckle, and the suction nozzle upper bracket 13 and the suction nozzle lower bracket 141 are fixed by screws 132. The suction nozzle lower bracket 141 is tightly fitted with the suction nozzle plug 142, and the suction nozzle lower bracket 141 is connected to the suction nozzle cover plate 144 through the buckle. In some embodiments, the suction nozzle upper bracket 13 and the suction nozzle lower bracket 141 can also be fixedly connected by other connection manners, such as snap coupling, tight fitting, adhesive bonding, or bolt coupling, etc.

In some embodiments, the bottom of the suction nozzle cover plate 144 defines gas inlets and positioning holes, and the gas inlets are sequentially communicated to the sliding unit 14 and the suction nozzle 11. The gas inlets, from left to right, are defined as a first gas inlet 1442, a central gas inlet 1441, and a second gas inlet 1443. The positioning holes, from left to right, are defined as a first positioning hole 1445, a center positioning hole 1444, and a second positioning hole 1446. The suction nozzle cover 2 defines a first gas outlet 211 and a second gas outlet 212. The positions of the positioning holes match the position of the elastic member 25, and the positions of the gas inlets match the positions of the gas outlets. The gas inlets are disposed parallel to the positioning holes. The gas inlets are configured to communicate with different gas channels during sliding the suction nozzle cover plate 144. Each positioning hole is a blind hole, and an opening size of the positioning hole can accommodate the top of the elastic member 25 and configured for positioning the elastic member 25.

In some embodiments, during sliding the suction nozzle assembly 100 to allow the top of the elastic member 25 to fall into the first positioning hole 1445, the central gas inlet 1441 is communicated with the second gas outlet 212, and other gas inlets are not communicated with the atomizing assembly 200. During sliding the suction nozzle assembly 100 to allow the top of the elastic member 25 to fall into the central positioning hole 1444, the first gas inlet 1442 is communicated with the first gas outlet 211, the second gas inlet 1443 is communicated with the second gas outlet 212, and other gas inlets are not communicated with the atomizing assembly 200. During sliding the suction nozzle assembly 100 to allow the top of the elastic member 25 to fall into the second positioning hole 1446, the central gas inlet 1441 is communicated with the first gas outlet 211, and other gas inlets are not communicated with the atomizing assembly 200. Thus, three suction states can be achieved.

In some embodiments, the gas inlets can also be one, two, four, or more. In some embodiments, there is one gas inlet, the suction nozzle assembly 100 slides, so that the one gas inlet is respectively communicated with the first gas outlet 211 and the second gas outlet 212, thereby achieving dual flavor switching. In some embodiments, there are two gas inlets, the suction nozzle assembly 100 slides along a direction, so that one of the two gas inlets can be communicated with the first gas outlet 211, and the other of the two gas inlets is blocked by the suction nozzle cover 21; and then the suction nozzle assembly 100 slides in an opposite direction, so that the blocked gas inlet can be not blocked and communicated with the second gas outlet 212, and the other gas inlet is blocked by the suction nozzle cover 21. This embodiment with two gas inlets can only achieve dual flavor switching. In some embodiments, there are four gas inlets, two outermost gas inlets can be disposed to achieve a mixed flavor, and two innermost gas inlets can achieve flavor switching. The purpose of disposing more than one gas inlet (such as disposing two gas inlets) between the two outermost gas inlets is to achieve taste switching in a short sliding stroke, which can reduce the production of condensate liquid.

The above one to four gas inlet solutions can be applied to the electronic atomizing device 1000 that includes two gas outlets (i.e., the first gas outlet 211 and the second gas outlet 212).

In the electronic atomizing device 1000 that includes three gas outlets, one gas inlet can also be used. In this way, by sliding the suction nozzle assembly 100, the one gas inlet can be selectively communicated with each of the three outlets, thereby achieving multiple flavors switching. In addition, in response to mixed flavors being required, two or more gas inlets can be disposed, so that multiple gas paths can be communicated during the sliding process.

During assembling the suction nozzle assembly 100, the liquid absorbing member 143 and the suction nozzle plug 142 can be fixed on the suction nozzle cover plate 144, and then the suction nozzle plug 142 can be sleeved with the suction nozzle lower bracket 141, to complete preliminarily fixed. Thus, the assembly of the sliding unit 14 is completed. The sliding unit 14 is inserted into the installation hole of the support cover 15. Then the suction nozzle lower bracket 141 is sleeved with the suction nozzle upper bracket 13. The screw 132 is tightened, so that the suction nozzle upper bracket 13 is fixed onto the suction nozzle lower bracket 141. Finally, the suction nozzle 11 is fixed onto the suction nozzle upper bracket 13, to complete the installation of the suction nozzle assembly 100.

In some embodiments, the suction nozzle cover plate 144 is made of POM (polyoxymethylene), so as to further enhance the wear resistance of the suction nozzle cover plate 144. Thus, the elastic member 25 is less likely to damage the structure of the suction nozzle cover plate 14, thereby making the structure more stable. In addition, the suction nozzle cover plate 144 with POM material has high strength and hardness, so that the elastic member 25 can abut against the suction nozzle cover plate 144 during sliding, further preventing the condensate liquid from being squeezed out.

In some embodiments, the sliding strip 131 can also be disposed on the bottom of the suction nozzle 11, instead of being disposed on the bottom of the suction nozzle upper bracket 13. In some embodiments, the sliding strips 131 can be disposed on both the bottom of the suction nozzle 11 and the bottom of the suction nozzle upper bracket 13. In this way, the support cover 15 can also support the suction nozzle 11, the suction nozzle bracket 13, and the sliding unit 14 that is fixedly connected to the suction nozzle bracket 13, so as to reduce the sliding friction, enhance the durability of the sliding structure, and improve the performance of the sliding structure.

Due to the above structure, the suction nozzle 11 can be driven by the sliding unit 14 to slide in the support cover 15. The top of the support cover 15 supports the bottom of the suction nozzle upper bracket 13 and/or the bottom of the suction nozzle 11, especially supports the sliding strip 131. Thus, during the sliding process, due to the support and limit of the support cover 15, the suction nozzle 11 cannot directly press the suction nozzle cover plate 144 downwards, reducing the possibility of the suction nozzle cover plate 144 directly pressing the suction nozzle cover 21 by the external force, reducing or even avoiding push and accumulation of the condensate liquid by the suction nozzle cover plate 144 during the sliding process, especially reducing or avoiding the situation where the condensate liquid is directly squeezed out of the suction nozzle cover 21. That is, since the suction nozzle 11 cannot directly press the suction nozzle cover plate 144 downwards, some condensed liquid can exist in a gap between the suction nozzle cover plate 144 and the suction nozzle cover 21, without being squeezed out and accumulated due to the excessive pressure of the suction nozzle cover plate 144 on the suction nozzle cover 21. The accumulated condensate liquid can easily block the first gas outlet 211 and the second gas outlet 212 of the suction nozzle cover 2, and even cause damage to electronic elements such as a control board 32 and a battery cell 33 because the accumulated condensate liquid flows towards the tail cover assembly 300.

In response to the suction nozzle 11 being slid to the center of the electronic atomizing device body, the first gas inlet 1442 is aligned with the first gas outlet 211 and communicated with the first atomizing gas channel 224, and the second gas inlet 1443 is aligned with the second gas outlet 212 and communicated with the second atomizing gas channel 226. The ceramic atomizing cores on both sides operate simultaneously, to achieve the suction of mixed flavors. In response to the suction nozzle 11 being slid to the left of the electronic atomizing device body, the first gas inlet 1442 is staggered with the first gas outlet 211, and the second gas inlet 1443 is staggered with the second gas outlet 212. Both the first gas inlet 1442 and the second gas inlet 1443 are blocked by the suction nozzle cover 21, thereby cutting off communication of the first gas inlet 1442 and the main gas outlet channel, and cutting off communication of the second gas inlet 1443 and the main gas outlet channel. The central gas inlet 1441 is aligned with the first gas outlet 211 and communicated with the first atomizing gas channel 224. At this time, the gas outlet channel of the suction nozzle assembly 100 is at the center of the suction nozzle 11. In response to the suction nozzle 11 being slid to the right of the electronic atomizing device body, the situation is analogous. That is, the suction nozzle 11 slides to any side of the electronic atomizing device body, communication of the central gas inlet 1441 and the main gas outlet channel is maintained, so that the main gas outlet channel of the suction nozzle assembly 100 is at the center of the suction nozzle 11. It experiences the least resistance and is least likely to form the condensate liquid.

In response to the suction nozzle 11 being slid to the far left of the electronic atomizing device body, the elastic member 25 falls into the second positioning hole 1446 under pressure. In response to the suction nozzle 11 being slid to the far right of the electronic atomizing device body, the elastic member 25 falls into the first positioning hole 1445 under pressure. In response to the suction nozzle 11 being slid to the center of the electronic atomizing device body, the top of the elastic member 25 is aligned with the center positioning hole 1444. The top of the elastic member 25 does not enter the positioning hole, and the elastic member 25 exerts upward pressure on the suction nozzle cover plate 144, causing the suction nozzle cover plate 144 to deform upwards. Thus, the gap between the suction nozzle cover plate 144 and the suction nozzle cover 21 further increases during the sliding process, further preventing the condensate liquid being squeezed out of the suction nozzle cover 21 during the sliding process.

As illustrated in FIGS. 2-3 and 5-9, in some embodiments, the upper part of the liquid cup 22 includes a first liquid chamber 221, a second liquid chamber 222, and a middle partitioning part 2212. The first liquid chamber 221 and the second liquid chamber 222 are two independent liquid chambers. The middle partitioning part 2212 is disposed between the first liquid chamber 221 and the second liquid chamber 222. A vertical elastic member installing chamber 223 is defined in the middle of the middle partitioning part 2212. A side of the elastic member installing chamber 223 close to the first liquid chamber 221 defines a first atomizing gas channel 224 and a first gas flow sensing channel 225. A side of the elastic member installing chamber 223 close to the second liquid chamber 222 defines a second atomizing gas channel 226 and a second gas flow sensing channel 227. A first communicating groove 228 is defined on the top of the liquid cup 22, so that the first atomizing gas channel 224 is communicated with the first gas flow sensing channel 225 through the first communicating groove 228 on the top of the liquid cup 22. A second communicating groove 229 is defined on the top of the liquid cup 22, so that the second atomizing gas channel 226 is communicated with the second gas flow sensing channel 227 through the second communicating groove 229 on the top of the liquid cup 22. The top of each of the first atomizing gas channel 224 and the second atomizing gas channel 226 is provided with a first annular flange, and the first annular flange is configured to better seal the suction nozzle cover 21. An end of the first annular flange close to the first communicating groove 228 defines a notch, so that the first communicating groove 228 is communicated with the first atomizing gas channel 224 through the notch of the first annular flange. An end of the first annular flange close to the second communicating groove 229 defines a notch, so that the second communicating groove 229 is communicated with the second atomizing gas channel 226 through the notch of the first annular flange. A protruding second annular flange is disposed on the suction nozzle cover 21 corresponding to the gas outlet. The second annular flange is configured to enhance the sealing between the suction nozzle cover 21 and the bottom of the sliding unit 14. The lower part of the liquid cup 22 defines a receiving chamber and a middle partitioning wall 2213. The liquid cup cover 24 is sleeved with the receiving chamber. A space formed by the liquid cup cover 24 and the receiving chamber is divided into two independent atomizing chambers by the middle partitioning wall 2213.

In some embodiments, the top plane of the liquid cup 22 is further provided with four protruding positioning columns 2210. The suction nozzle cover 21 defines four third positioning holes 215 corresponding to the positioning columns 2210. During installation, the positioning columns 2210 are installed into the third positioning holes 215, so as to further fix the suction nozzle cover 21 and prevent deformation of the suction nozzle cover 21 during sliding the suction nozzle 11.

In some embodiments, a heating part of the ceramic atomizing core is disposed on the bottom surface of the ceramic atomizing core. The liquid in the liquid cup 22, such as e-liquid, permeates a ceramic layer of the ceramic atomizing core and is heated by the heating part, so that atomizing gas is formed on the bottom surface of the ceramic atomizing core. There are multiple protruding support columns 2211 around the atomization core installing base 220, and the support columns 2211 are configured to ensure the gap between the liquid cup cap 24 and the bottom of the liquid cup 22 during the installation process.

In some embodiments, the suction nozzle cover 21 defines the first gas outlet 211 corresponding to the first atomizing gas channel 224, and the second gas outlet 212 corresponding to the second atomizing gas channel 226. The suction nozzle cover 21 includes a first gas plug 213 corresponding to the first gas flow sensing channel 225 and configured for being inserted into the first gas flow sensing channel 225, and a second gas plug 214 corresponding to the second gas flow sensing channel 227 and configure for being inserted into the second gas flow sensing channel 227. The first gas plug 213 is configured to seal the first gas flow sensing channel 225 on one side away from the atomizing gas channel. The second gas plug 214 is configured to seal the second gas flow sensing channel 227 on one side away from the atomizing gas channel. The first gas plug 213 defines a gas groove 210 that is communicated with the first communicating groove 228, and the second gas plug 214 defines a gas groove 210 that is communicated with the second communicating groove 229. Thus, gas in the gas flow sensing channel can flow into the atomizing gas channel through the gas groove 210 and the communicating groove.

In some embodiments, the liquid cup cover 24 is configured to seal the bottom of the liquid cup 22, and a protruding part 241 is disposed on the liquid cup cover 24. The protruding part 241 is located directly below the ceramic atomizing core 23, so as to support the ceramic atomizing core 23 and prevent the ceramic atomizing core 23 from falling off. The liquid cup cap 24 defines an upward protruding atomizing vent hole 243 corresponding to the ceramic atomizing core 23. The atomizing vent hole 243 can be communicated with external atmosphere. The atomizing vent hole 243 is configured to transport the external atmosphere to the bottom surface of the ceramic atomizing core 23 through the atomizing vent hole 243 during suction, and then carry the aerosol towards the first atomizing gas channel 224 through the gas flow channel. The number of atomizing vent holes 243 can be two, so as to carry the aerosol generated on the bottom surface of another ceramic atomizing core 23 towards the second atomizing gas channel 226. The liquid cup cover 24 is further provided with two independent upward protruding gas flow sensing tubes 242, one gas flow sensing tube 242 is disposed directly below the first gas plug 213, and the other gas flow sensing tube 242 is disposed directly below the second gas plug 214.

In some embodiments, each gas flow sensing tube 242 includes two stepped sections, namely a bottom gas channel tube 2421 and a top gas channel tube 2422. The section of the gas flow sensing tube 242 close to the liquid cup cap 24 is the bottom gas channel tube 2421, and the section of the gas flow sensing tube 242 close to the liquid cup 22 is the top gas channel tube 2422. The surface of the bottom gas channel tube 2421 includes an annular protruding part, and the bottom gas channel tube 2421 is sealed with the liquid cup 22 during installation, which can further improve the sealing effect. The top gas channel tube 2422 protrudes from the bottom gas channel tube 2421. A cross-sectional size of the top gas channel tube 2422 is less than that of the bottom gas channel tube 2421, so that it is difficult for the condensate liquid to flow into the top gas channel tube 2422 and the bottom gas channel tube 2421 from, such as, the second gas flow sensing channel 227. Thus, it is difficult for the condensate liquid to enter the tail cover assembly 300.

Through the above structural settings, the ceramic atomizing core that the heating part disposed on the bottom of the ceramic atomizing core serves as the heating core, so that the atomized smoke flows out from the bottom of the ceramic atomizing core. Furthermore, the first atomizing gas channel 224 and the second atomizing gas channel 226 are defined in the center of the liquid cup 22, the exhaust channel of the electronic atomizing device 1000 is close to the center of the entire electronic atomizing device 1000, reducing the distance between the gas outlets of the first liquid chamber 221 and the second liquid chamber 222. Thus, the gas outlet of the atomizer can be communicated with the center of the suction nozzle 11 during the sliding process, ensuring a smooth exhaust channel in the suction nozzle 11 and reducing the probability of condensate liquid formation. The atomizing gas channels and gas flow sensing channels that are independent to each other are defined in the liquid cup 22, and the atomizing gas channels are communicated with the gas flow sensing channels on the top of the liquid cup 22. The gas outlet of the suction nozzle cover 21 can be simultaneously communicated with the gas flow sensing channel and the atomizing gas channel. By disposing two independent liquid chambers, two independent atomizing gas channels, two independent gas flow sensing channels, and a bottom independent gas channel on the liquid cup 22, inhaling through a suction nozzle outlet can achieve simultaneous operation of the atomizing gas channel and the gas flow sensing channel. The gas plug with a unique structure can prevent the condensate liquid from contaminating the gas flow sensing channel.

As illustrated in FIGS. 2 and 9-10, in some embodiments, the liquid cup cover 24 is interference-fitted with the tail cover bracket 31. The top of the tail cover bracket 31 defines a cavity to accommodate the bottom of the liquid cup cover 24. The tail cover bracket 31 defines an atomizing gas channel inlet 311 communicated with the atomizing vent hole 243 and a gas flow sensing inlet 312 communicated with the gas flow sensing tube 242. An induction switch installing slot 313, a bolt column 314, and a reverse inserting wall 315 are disposed in the tail cover bracket 31. The control board 32 is fixed by using the bolt column 314 and additionally fixed by using the reverse inserting wall 315. The control board 32 and the gas flow sensing inlet 312 are disposed on the same side of the tail cover bracket 31. A display screen module, a gas flow sensing module, a button module, and a Type-C charging interface are disposed on the control board 32. The bottom of the shell 400 defines a Type-C opening.

The operation principle of the electronic atomizing device 1000 of the present disclosure is as follows.

In the sliding electronic atomizing device 1000, the gas inlet of the suction nozzle assembly 100 is switched to a target position by sliding the suction nozzle assembly 100. In use, the suction nozzle assembly 100 slides left and right in the support cover 15. In response to the target position for the sliding of the suction nozzle assembly 100 being the center position of the electronic atomizing device body, the top of the elastic member 25 is aligned with the central positioning hole 1444, the first gas inlet 1442 is aligned with the first gas outlet 211 and communicated with the first atomizing gas channel 224, and the second gas inlet 1443 is aligned with the second gas outlet 212 and communicated with the second atomizing gas channel 226. That is, in this case, the gas paths inside the first liquid chamber 221 and the second liquid chamber 222 are both communicated. During inhaling by the user, the gas pressure in the gas flow sensing inlet 312 and the gas pressure in the gas flow sensing tube 242 communicated with the gas flow sensing inlet 312 change, causing the gas flow induction switch 34 to sense and trigger the control circuit, starting the device to operate. The ceramic atomizing core 23 in the first liquid chamber 221 and the ceramic atomizing core 23 in the second liquid chamber 222 simultaneously heats and atomizes to produce aerosols. The gas generated by atomizing the liquid in the first liquid chamber 221 and the gas generated by atomizing the liquid in the second liquid chamber 222 is collected in the suction nozzle cover 21 through the first gas outlet 211 and the second gas outlet 212. The mixed smoke enters the sliding unit 14 through the first gas inlet 1442 and the second gas inlet 1443, and the mixed smoke is then inhaled by the user through the suction nozzle 11. The e-liquid with different flavors is injected into the first liquid chamber 221 and the second liquid chamber 222, the electronic atomizing device 1000 with a mixed flavor can be obtained.

In response to the target position for the sliding of the suction nozzle assembly 100 being the left side of the electronic atomizing device body, the elastic member 25 falls into the second positioning hole 1446 under pressure. The first gas inlet 1442 is staggered with the first outlet 211, and the second gas inlet 1443 is staggered with the second gas outlet 212. Both the first gas inlet 1442 and the second gas inlet 1443 are blocked by the suction nozzle cover 21, thereby cutting off the communication of the first gas inlet 1442 and the main gas outlet channel, and cutting off the communication of the second gas inlet 1443 and the main gas outlet channel. The first atomizing gas channel 224 is communicated with the left gas flow sensing inlet 312 through the first communicating groove 228 and the left first atomizing gas channel 242. That is, in this case, the gas path in the first liquid chamber 221 is communicated, and the gas path in the second liquid chamber 222 is blocked by the suction nozzle cover 21. During inhaling by the user, air enters the tail cover assembly 300 through the Type-C opening, and the pressure in the left gas flow sensing inlet 312 and the pressure in the gas flow sensing tube 242 change, causing the gas flow induction switch 34 to sense and trigger the control circuit. Thus, the ceramic atomizing core of the first liquid chamber 221 can be electrically heated and atomized, to produce the aerosols. The aerosols are carried by the air entering through the left atomizing vent hole 243, flow through the first atomizing gas channel 224, the first outlet 211, and the central gas inlet 1441, then enter the sliding unit 14, and finally inhaled by the user through the suction nozzle 11.

In response to the target position for the sliding of the suction nozzle assembly 100 is the right side of the electronic atomizing device body, the elastic member 25 falls into the first positioning hole 1445 under pressure, and the gas path in the second liquid chamber 222 is communicated, and the gas path in the first liquid chamber 221 is blocked. The ceramic atomizing core of the second liquid chamber 222 is powered on and operates, and its principle is the same as the ceramic atomizing core of the first liquid chamber 221, which is not repeated here.

In some embodiments, the sliding arrangement of the suction nozzle assembly 100 relative to the support cover 15 can also be forward and backward sliding, which is not repeated here.

There is no the gas flow induction switch 34 and no the gas flow channel related to the gas flow induction switch 34 in the first embodiment.

In the present disclosure, PCB stands for Printed Circuit Board, which does not have any components on its surface. PCBA, short for PCB+Assembly, refers to placing electronic components (such as ICs, resistors, capacitors, inductors, etc.) onto the PCB through soldering or other manners.

As illustrated in FIG. 11, the fixed part 111 can be located on a side of the sliding unit 14, and configured for mating with the PCBA 61.

The PCBA 61 is provided with a sliding switch handle 611, a sliding switch body 612, a push-button switch 613, and multiple PCBA positioning holes 614. One end of the sliding switch handle 611 is disposed on the sliding switch body 612, and the other end of the sliding switch handle 611 is matched with the fixed part 111. The multiple PCBA positioning holes 614 are configured to fix the PCBA 61 on the support cover 15.

The PCBA 61 and the control board 32 (without the gas flow induction switch 34) in the first embodiment can form the control assembly in the second embodiment. The PCBA 61 is electrically connected to the control board 32, the control board 32 is connected to the atomizing assembly 200 and the battery cell 33.

The fixed part 111 on the sliding unit 14 is matched with the sliding switch handle 611 on the PCBA 61, thus, the sliding of the sliding unit 14 of the suction nozzle assembly 100 can drive the sliding of the sliding switch handle 611, thereby completing the circuit switching. That is, the fixed part 111 is fixed to the sliding switch handle 611, so that sliding of the sliding unit 14 is able to drive sliding of the sliding switch handle 611. The user can simultaneously switch the gas paths and circuits with a simple action, thereby obtaining the smoke with different flavors through the same device.

A third embodiment of the present disclosure provides the electronic atomizing device 1000. The difference between the electronic atomizing device 1000 in the third embodiment and the electronic atomizing device 1000 in the first embodiment is that: in the third embodiment, there are no injecting holes 12 on two opposite sides of the suction nozzle 11, and there is no liquid plug 500. The suction nozzle cover 21 is disposed without an oil injection chamber.

A fourth embodiment of the present disclosure provides the electronic atomizing device 1000. The difference between the electronic atomizing device 1000 in the fourth embodiment and the electronic atomizing device 1000 in the first embodiment is that: in the fourth embodiment, a housing of the electronic atomizing device 1000 is configured to accommodate at least a part of the sliding unit 14, and at least one of the suction nozzle unit 102 and the sliding unit 14 is supported by the housing. The support cover 15 can be fixedly connected to the shell 400 in the first embodiment, to form the housing. In some embodiments, the housing can be integrated by using the support cover 15 and the shell 400 in the first embodiment. In this way, the impact on the components in sliding contact with the sliding unit 14 during the sliding process can also be reduced.
