ELECTRONIC ATOMIZER

Description

FIELD OF THE INVENTION

The present invention relates to the field of atomization technology, and more particularly to an electronic atomizer.

DESCRIPTION OF THE RELATED ART

The electronic atomization technology is a technology that applies electricity to heat a liquid to a boiling point for evaporation to generate atomized vapor and is currently mostly applied to the field of electronic atomizers. With the innovation and progress of the atomization technology, the electronic atomization technology is being applied to various other fields, such as fields of beauty care and medical care. In the field of atomization technology, the most commonly known concern is liquid leaking. Liquid leaking influences users' experience, and the leaking liquid also contaminate and damage electronic parts and other objects. In brief, liquid leaking is a fatal issue for atomizers, and as such, it is desired to develop a reliable and perfect atomizer structure to avoid the occurrence of such an issue. At present, the known techniques mostly adopt immersing a liquid-conducting member of an atomizer in an atomizable liquid or arranging a liquid feeding opening to control a liquid feeding amount, or the atomizable liquid is kept from contacting the liquid-conducting member when not in use, and during the course of use, the liquid-conducting member is held in a state of being persistently contacting with the liquid stored in a liquid storage compartment.

The terms, such as “first” and “second” are adopted only for the purposes of description and should not be interpreted as indicating or implying relative importance or implicitly suggesting the quantity of a technical feature indicated thereby. “Multiple” means two or more than two, unless specifically defined otherwise.

As shown in FIGS. 1-18, an electronic atomizer comprises a liquid storage unit 10 in which an atomizable liquid is storable, an atomization unit 20 arranged at a rear side of the liquid storage unit 10, a gas supply unit 30 supplying gas to the liquid storage unit 10, and a control unit 40 controlling operation of the atomization unit 20 and the gas supply unit 30. The liquid storage unit 10 comprises a liquid storage compartment 1, and a sealing member 2 arranged between the liquid storage compartment 1 and the atomization unit 20, wherein the sealing member 2 hermetically closes the liquid storage compartment 1. The sealing member 2 is formed with a gas conducting hole 21 through which an atomized gas is conducted out, at least one liquid ingress one-way valve 22 and at least one gas ingress one-way valve 23. The liquid ingress one-way valve 22 controls the liquid of the liquid storage compartment I to move, in a one-way manner, into the atomization unit 20 for atomization. The gas ingress one-way valve 23 is connected to the gas supply unit 30 to supply gas, in a one-way manner, into an interior of the liquid storage compartment 1.

The liquid storage compartment 1 mainly functions to store and hold the atomizable liquid. The sealing member 2 hermetically closes the liquid storage compartment 1, so that in a condition of being not used, the atomizable liquid in the liquid storage unit 10 is not in direct contact engagement with and the atomization unit 20. The atomization unit 20 mainly functions as essential hardware for atomization of the atomizable liquid. The atomization unit 20 comprises a liquid-conducting body 201, and a heat-generating body 202 wrapping around an outside wall of the liquid-conducting body 201. The liquid-conducting body 201 is arranged to correspond to a bottom of a liquid egress end of the liquid ingress one-way valve 22, and mainly functions to heat the atomizable liquid to a boiling point to form atomized vapor. The atomized vapor and air that enters the atomization unit 20 from the outside are mixed to form an aerosol, and the aerosol so formed flows out through the gas conducting hole 21 of the sealing member 2. A second gas guide tube 60 is connected to the gas conducting hole 21, and the atomized vapor flows through the second gas guide tube 60 to outside of the electronic atomizer. The control unit 40 mainly functions to supply electrical energy required for atomization carried out by the atomization unit 20, and controls activation/deactivation of the atomization unit 20 and shut-down/open-up of the gas supply unit 30.

In the course of use of the electronic atomizer, when in operation, the control unit 40 controls the gas supply unit 30 to open up and the gas supply unit 30 generates gas to supply the gas to the site of the gas ingress one-way valve 23 of the liquid storage unit 10, so that a gas pressure at the site of the gas ingress one-way valve 23 of the liquid storage unit 10 is increased, and the increased gas pressure pushes open the gas ingress one-way valve 23 of the sealing member 2 to allow the gas to get into the interior of the liquid storage compartment 1, thereby increasing a gas pressure in the interior of the liquid storage compartment 1, and the gas pressure, when increased to a predetermined level, becomes compressing the atomizable liquid to thereby push open the liquid ingress one-way valve 22 to allow the atomizable liquid in the interior of the liquid storage compartment 1 to pass through the liquid ingress one-way valve 22 and be conducted to the atomization unit 20, and the control unit 40 controls the operation of the atomization unit 20 to have heat generated in the atomization unit 20 atomizing the atomizable liquid to form atomized vapor, and the atomized vapor is mixed with air that gets into the atomization unit 20 to form an aerosol (atomized gas), and the atomized gas flows out by way of the gas conducting hole 21 of the sealing member 2; when not in operation, the gas ingress one-way valve 23 is in a closed state, and the liquid ingress one-way valve 22 is also in a closed state, and the gas pressure of the atomization unit 20 and the gas pressure in the interior of the liquid storage unit 10 are generally in a balanced state, and the atomizable liquid in the liquid storage compartment 1 does not flow to the atomization unit 20.

In the electronic atomizer provided in the present invention, the gas supply unit 30, the liquid storage unit 10, and the control unit 40 are provided, and the liquid ingress one-way valve 22 and the gas ingress one-way valve 23 are arranged on the sealing member 2, wherein the liquid ingress one-way valve 22 can be just a single one, or multiple ones can be included, and the gas ingress one-way valve 23 can be just a single one, or multiple ones can be included, the numbers thereof being not specifically limited; the gas ingress one-way valve 23, taking the sealing member 2 as a boundary, faces from the side associated with the gas supply unit 30 toward the side associated with the liquid storage compartment 1 of the liquid storage unit 10, and it is appreciated that the gas ingress one-way valve 23, when set in an open state, only allows the gas generated by the gas supply unit 30 to flow in a direction toward the liquid storage compartment 1, while preventing gas or the atomizable liquid in the interior of the liquid storage compartment 1 from flowing toward the gas supply unit 30; the liquid ingress one-way valve 22, taking the sealing member 2 as a boundary, faces from the side associated with the liquid storage compartment 1 of the liquid storage unit 10 toward the side associated with the atomization unit 20, and it is appreciated that the liquid ingress one-way valve 22, when set in an open state, only allows the atomizable liquid in the interior of the liquid storage compartment 1 to flow toward the atomization unit 20, while preventing the atomizable liquid or gas in the interior of the atomization unit 20 from flowing toward the liquid storage compartment 1; the control unit 40 controls activation or deactivation of the operations of the gas supply unit 30 and the atomization unit 20, and the gas supply unit 30 feeds gas, through the gas ingress one-way valve 23, into the liquid storage compartment 1 to thereby vary the gas pressure in the interior of the liquid storage compartment 1 so as to break the original balance between the gas pressures of the liquid storage compartment 1 and the atomization unit 20 to make the gas pressure in the interior of the liquid storage compartment 1 greater than the gas pressure of the atomization unit 20, and the gas pressure in the interior of the liquid storage compartment 1 compresses the atomizable liquid to open up the liquid ingress one-way valve 22 to allow the atomizable liquid in the interior of the liquid storage compartment 1 to flow toward the atomization unit 20 so as to achieve the purpose of liquid supplying, and when not in operation, the atomizable liquid in the interior of the liquid storage compartment 1 is not in direct contact with the atomization unit 20, meaning the atomizable liquid in the interior of the liquid storage compartment 1 is not in direct communication with the atomization unit 20, so as to avoid the likelihood and potential risk of leakage of the atomizable liquid caused by the liquid pressure of the liquid storage compartment 1 and the capillary effect of a liquid-conducting portion of the atomization unit 20 (namely the liquid-conducting body 201); the control unit 40 controls the operations of the atomization unit 20 and the gas supply unit 30, such that an amount of gas supplied from the gas supply unit 30 is controllable according to the consumption of the atomizable liquid of the atomization unit 20 and the time period of atomization, in order to achieve balance between a liquid supplying amount and a consumption amount of the atomizable liquid to thereby achieve balanced liquid supply.

As shown in FIGS. 12-15, preferably, the liquid ingress one-way valve 22 comprises a hollow liquid ingress portion 221 for directional liquid ingress and a liquid ingress valve core 222 arranged at the liquid egress end of the liquid ingress portion 221 and having a liquid ingress slit 2221. The atomization unit 20 is arranged to correspond to a liquid egress end of the liquid ingress slit 2221 of the liquid ingress valve core 222. It is appreciated that the liquid ingress portion 221 is in communication with the atomizable liquid of the liquid storage compartment 1. The liquid ingress valve core 222 controls opening and closing of the liquid ingress one-way valve 22. The liquid ingress valve core 222 is formed, at the liquid egress end, with the self-closing liquid ingress slit 2221. When the liquid ingress one-way valve 22 is in the closed state, the liquid ingress slit 2221 is closed (meaning there is no gap formed between inside walls of the liquid ingress slit 2221), and when the liquid ingress one-way valve 22 is in the open state, the liquid ingress slit 2221 is opened (meaning there is a gap formed between the inside walls of the liquid ingress slit 2221). Further, preferably, in the sealing member 2, at least the liquid ingress valve core 222 is a component made of an elastic material. The liquid ingress valve core 222 is exposed at the side associated with the atomization unit 20. When the electronic atomizer is not in operation, the liquid ingress valve core 222 is acted upon by a reverse pressure, and the liquid ingress valve core 222 is flatter than the liquid ingress portion 221, and side walls of the liquid ingress valve core 222 are compressed by the air pressure at the side associated with the atomization unit 20, and the pressure acting at the site of the liquid ingress slit 2221 is almost negligible, so that the liquid ingress slit 2221 of the liquid ingress valve core 222 is caused to close more tightly; and when the electronic atomizer is in operation, the gas supply unit 30 feeds gas into the interior of the liquid storage compartment 1, and the internal pressure of the liquid storage compartment 1 is increased, and the pressure compresses the atomizable liquid in the interior of the liquid storage compartment 1 to thereby lead to a trend for the atomizable liquid to flow out of the liquid storage compartment 1, and when the gas pressure in the interior of the liquid storage compartment 1 becomes excessively large, the pressure at the site of the liquid ingress portion 221 compresses the atomizable liquid to thereby open up the liquid ingress slit 2221 of the liquid ingress valve core 222, so that the atomizable liquid can be conducted into the atomization unit 20 to be atomized by the atomization unit 20.

As shown in FIGS. 12-15, preferably, the gas ingress one-way valve 23 comprises a hollow gas ingress portion 231 for directional gas ingress and a gas ingress valve core 232 arranged at the gas egress end of the gas ingress portion 231 and having a gas ingress slit 2321. It is appreciated that the gas ingress portion 231 is in communication with an output end of the gas supply unit 30, and the gas ingress valve core 232 is in communication with the gas ingress portion 231. The gas ingress valve core 232 controls opening and closing of the gas ingress one-way valve 23. The gas ingress valve core 232 is formed, at the gas egress end, with the self-closing gas ingress slit 2321. When the gas ingress one-way valve 23 is in the closed state, the gas ingress slit 2321 is closed (meaning there is no gap formed between inside walls of the gas ingress slit 2321), and when the gas ingress one-way valve 23 is in the open state, the gas ingress slit 2321 is opened (meaning there is a gap formed between the inside walls of the gas ingress slit 2321). Further, preferably, in the sealing member 2, at least the gas ingress valve core 232 is a component made of an elastic material. The gas ingress valve core 232 is exposed at the side associated with the liquid storage unit 10, and the gas ingress valve core 232 is flatter than the gas ingress portion 231. When the electronic atomizer r is not in operation, the gas ingress valve core 232 is acted upon by a reverse pressure, and side walls of the gas ingress valve core 232 are compressed by the liquid pressure at the side associated with the liquid storage unit 10, and the pressure acting at the site of the gas ingress slit 2321 is almost negligible, so that the gas ingress slit 2321 of the gas ingress valve core 232 is caused to close more tightly, and when the electronic atomizer is in operation, the gas supply unit 30 operates and the gas supply unit 30 generates gas, and the pressure at the site of the gas ingress portion 231 and the gas ingress valve core 232 is gradually increased, and the pressure compresses the liquid ingress valve core 222 to thereby lead to a trend for the gas generated by the gas supply unit 30 to flow into the liquid storage compartment 1, and when the gas pressure at the site of the gas ingress portion 231 and the gas ingress valve core 232 is increased to a predetermined level, the pressure pushes open the gas ingress slit 2321 of the gas ingress valve core 232, so that the gas generated by the gas supply unit 30 may get into the interior of the liquid storage unit 10 to thereby increase the gas pressure in the interior of the liquid storage compartment 1, and the gas pressure, when increased to a predetermined level, compresses the atomizable liquid to push open the liquid ingress slit 2221 of the liquid ingress valve core 222, thereby allowing the atomizable liquid to be conducted into the atomization unit 20 to be atomized by the atomization unit 20.

The gas ingress portion 231 and the gas ingress valve core 232 of the gas ingress one-way valve 23 can be made as separate structures, and the two are fixedly connected; or alternatively, the gas ingress portion 231 and the gas ingress valve core 232 can be integrally formed as a one-piece structure. Preferably, the gas ingress portion 231 and the gas ingress valve core 232 are of a one-piece structure as being integrally molded during fabrication, in order to save steps of assembling, and also to better the leak-tightness of the gas ingress one-way valve 23 to prevent the atomizable liquid from leaking at the site of the gas ingress one-way valve 23. The liquid ingress portion 221 and the liquid ingress valve core 222 can be made as separate structures, and the two are fixedly connected; or alternatively, the liquid ingress portion 221 and the liquid ingress valve core 222 can be integrally formed as a one-piece structure. Preferably, the liquid ingress portion 221 and the liquid ingress valve core 222 are of a one-piece structure as being integrally molded during fabrication, in order to save steps of assembling, and also to better the leak-tightness of the liquid ingress one-way valve 22 to prevent the atomizable liquid from leaking at the site of the liquid ingress one-way valve 22.

Further, preferably, an inside diameter of the liquid ingress portion 221 gradually decreases from the liquid ingress end toward the liquid egress end, or alternatively, the liquid ingress portion 221 comprises multiple sections having inside diameters that are decreased gradually. Here, multiple sections refer to the liquid ingress portion 221 being divided into multiple sections, and it is provided that the inside diameter of each of the sections is gradually decreased, or for each specific section, the inside diameter is fixed, and the inside diameters of the sections are decreased, in a stepwise, section by section manner, from the liquid ingress end to the liquid egress end. This arrangement helps increase the speed of the atomizable liquid of the liquid storage compartment I flowing into the liquid ingress portion 221, so as to increase, to some extents, the speed of conducting the liquid. Of course, the inside diameter of the liquid ingress portion 221 is fixed from the liquid ingress end toward the liquid egress end. Further, preferably, the liquid ingress end of the liquid ingress portion 221 is provided with a second guiding surface 2211 that inclines toward interior of the liquid ingress portion 221. The second guiding surface 2211 is in communication with the liquid storage compartment 1 to conduct the atomizable liquid into the liquid ingress portion 221, so as to make the atomizable liquid entering the liquid ingress portion 221 in a more accurate and more efficient manner to speed up a liquid supply rate to the atomization unit 20

Further, preferably, an inside diameter of the gas ingress portion 231 gradually decreases from the gas ingress end toward the gas egress end, or alternatively, the gas ingress portion 231 comprises multiple sections having inside diameters that are decreased gradually. Here, multiple sections refer to the gas ingress portion 231 being divided into multiple sections, and it is provided that the inside diameter of each of the sections is gradually decreased, or for each specific section, the inside diameter is fixed, and the inside diameters of the sections are decreased, in a stepwise, section by section manner, from the gas ingress end to the gas egress end. This arrangement helps increase the speed of the gas generated by the gas supply unit 30 flowing into the gas ingress portion 231, so as to increase, to some extents, the speed of gas supplying thereby shortening a response time from starting supply of gas to the liquid ingress valve core 222 opening to supply liquid to the atomization unit 20. Further, preferably, the gas ingress end of the gas ingress portion 231 is provided with a first guiding surface 2311 that inclines toward interior of the gas ingress portion 231. The first guiding surface 2311 is in communication with the output end of the gas supply unit 30 to conduct gas into the gas ingress portion 231, so as to make gas entering the gas ingress portion 231 in a more accurate and more efficient manner to speed up a gas supply rate to the liquid storage compartment 1.

It is appreciated that it is possible that, in the sealing member 2, only the liquid ingress valve core 222 and the gas ingress valve core 232 are elastic material-made components, or it is possible that the entirety of the sealing member 2 is an elastic sealing member 2, and the output end of the gas supply unit 30 is in communication with the gas ingress portion 231 for pushing open the gas ingress valve core 232 to feed gas into the liquid storage unit 10, and the gas supply unit 30 provides a gas pressure to push open the liquid ingress valve core 222 to thereby supply the atomizable liquid to the atomization unit 20, and the control unit 40 controls activation or deactivation of operations of the gas supply unit 30 and the atomization unit 20.

The first gas guide tube 50 is connected with the gas flow orifice 31. Connection between the first gas guide tube 50 and the gas flow orifice 31 can be made in various ways, such as inserting, engaging, and force fitting, and preferably, the first gas guide tube 50 is inserted into the gas flow orifice 31 and force fitting is formed between the two. Gas generated by the gas supply unit 30 flows through the first gas guide tube 50 to the gas ingress end of the gas ingress one-way valve 23 to make the gas ingress one-way valve 23 to convert from the closed state to the open state, and air is outputted through the gas egress end of the gas ingress one-way valve 23 to supply gas into the liquid storage compartment 1.

As shown in FIGS. 16-18, the atomization unit 20 comprises a liquid-conducting body 201 and a heat-generating body 202 wrapping around an outside wall of the liquid-conducting body 201.

S-8, the control unit 40 comprises a housing 41, and arranged inside the housing 41 are a battery mounting frame 42, a battery 43, a control switch 44, a control circuit board 45, and electrode spring pins 46. The battery 43 is mounted on the battery mounting frame 42. Electrical connection is made among the control circuit board 45, the control switch 44, the battery 43, the gas supply unit 30, and the atomization unit 20 in order to control the gas supply unit 30 and the atomization unit 20 to turn on or off. The electrode spring pins 46 electrically connects the atomization unit 20 with the battery 43. The battery 43 functions to supply energy and a rechargeable lithium battery 43 is adopted, and a charging device and a charging port 49 are provided for charging of the battery 43. The battery mounting frame 42 functions to fix and protect the control circuit board 45 and the battery 43. The electrode spring pins 46 are mounted on and fixed to the battery mounting frame 42 for electrically connecting the control unit 40 and the atomization unit 20. The electrode spring pins 46 include magnets 47 sleeved thereon, and the magnets 47 provide an attracting force to ensure no gap of connection between the electrode spring pins 46 and the lead-out electrodes 204 of the atomization unit 20 to enhance the performance of electrical conduction. The control switch 44 can be a gas flow sensing switch, wherein the gas flow sensing switch mainly functions to sense gas flow variation when a user vapes to cause gas pressure variation so as to trigger on the control switch 44, and senses no gas pressure variation when vaping stops so as to shut off the control switch 44, such as microphone switch and pressure sensitive switch, and further comprising flow-sensing sealing member 48, the flow-sensing sealing member 48 sealing the gas flow sensing switch to ensure a direction in which gas flowing to have the gas flow sensing switch smoothly sensing the variation of gas pressure to thereby activate the function of the gas flow sensing switch. Here, the control switch 44 can also be a pressing type button switch, which is conducted on when pressed down, this being understood as pressing down the switch conducting on a circuit of the atomization unit 20 and the gas supply unit 30 to make the atomization unit 20 and the gas supply unit 30 operating, and which shuts off when released, this being understood as releasing the button switch shutting off the circuit of the atomization unit 20 and the gas supply unit 30 to make the atomization unit 20 and the gas supply unit 30 stop operating, or alternatively, the gas flow sensing switch and the button switch are both used. The control circuit board 45 functions to stabilize an output voltage of the battery 43 to the atomization unit 20 and to control the control switch 44 to immediately operate or to delay operating, and to control the operation time and activation and deactivation of the gas supply unit 30, and to control the charging device to charge the battery 43. The gas supply unit 30 can be a miniature peristaltic air pump or a miniature motor-driving-piston device, mainly functioning to provide power to supply gas to the site of the gas ingress one-way valve 23 of the liquid storage unit 10 to increase the gas pressure at the site of the gas ingress one-way valve 23 of the liquid storage unit 10, and the increased gas pressure may push open the gas ingress one-way valve 23 of the sealing member 2 to allow gas to get into the interior of the liquid storage compartment 1 to change the gas pressure of the liquid storage compartment 1 to thereby open the liquid ingress one-way valve 22 to supply liquid to the atomization unit 20.
