It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this disclosure can be combined with other embodiments.

With the advancement of small household electrical appliance technology, the problem of indoor dryness in autumn and winter has been alleviated. The emergence of humidifiers can increase indoor air humidity, making it more suitable for living. In addition to the basic function of increasing humidity, humidifiers can also be used in combination with aromatic essential oils, air fresheners, Chinese herbal medicines, and other functional components. The water mist containing these functional components can be sprayed into the air, thereby achieving effects such as mood relaxation, disease treatment, and air quality improvement, providing users with a better experience.

However, common humidifiers typically have straight spray outlets, with water mist fixedly sprayed in one direction, resulting in a very limited spray range. This causes the sprayed water mist to distribute unevenly and creates dead zones. Users usually have to move the humidifier to obtain different spray positions and/or directions, which is inconvenient.

To address the above technical problems, inventors of the present disclosure have proposed at least the following embodiments after long-term research.

Referring to FIGS. 1-4, FIG. 1 is a schematic perspective view of an assembled spray device according to an embodiment of the present disclosure from one angle. FIG. 2 is a schematic perspective view of the assembled spray device according to an embodiment of the present disclosure from another angle. FIG. 3 is a schematic sectional view of the spray device from the angle as shown in FIG. 2. FIG. 4 is an enlarged view of an area “A” shown in FIG. 3. An embodiment of the present disclosure provides a spray device 1 for generating aerosols and transferring them outwardly. The spray device 1 include a device body 2, an upper cover 8, and a movable member 3.

The device body 2 defines a mist generation chamber 222. The upper cover 8 is connected to the device body 2 and defines a through hole 211. A mist generating unite 29 is mounted in the installation cavity 4 so that mist is generated in the mist generation chamber 222. The movable member 3 is mounted in the upper cover 8 and is rotatable relative to the upper cover 8. The movable member 3 is provided with a mist outlet 321 through which mist generated in the mist generation chamber 222 is sprayed out of the spray device 1. At least a portion of the movable member 3 is exposed to the upper cover 8 through the through hole 211. As the movable member 3 rotates, the mist outlet 321 can be oriented in different directions so that the mist can be sprayed out through the mist outlet 321 in different directions.

Specifically, the movable member 3 is capable of rotating relative to the installation cavity 4 in two directions. The upper cover 8 can also defines an installation cavity 4. The through hole 211 communicates with the installation cavity 4. The movable member 3 is movably mounted in the installation cavity 4. The mist outlet 321 is in communication with the mist generation chamber 222. At least a portion of the movable member 3 is exposed to the installation cavity 4 through the through hole 211. The movable member 3 can further define a mist channel 32. The mist outlet 321 communicates with the installation cavity 4 via the mist channel 32.

In the structure provided in this embodiment, by rotatably installing the movable member 3 in the installation cavity 4 and allowing a portion of the movable member 3 to extend to be exposed to the outside of the spray device 1 through the through hole 211, the orientation of the mist outlet 321 provided on the movable member 3 can be adjusted by rotating the movable member 3. When the mist outlet 321 is rotated to a position where it is exposed through the through hole 211, aerosols from the mist channel 32 can be sprayed in different directions through the mist outlet 321, achieving the effect of flexibly adjusting the orientation of the mist outlet 321. This enables the spray device 1 to spray aerosols in multiple directions, thereby enhancing the usability of the spray device 1.

In a specific embodiment of the present disclosure, a first spherical surface 31 can be provided on the movable member 3, like on the outer periphery of the movable member 3, and the movable member 3 can have an outer contour that is at least partially spherical. The upper cover 8 may be provided with a second spherical surface 41 that corresponds to the first spherical surface 31, allowing the first spherical surface 31 to cooperate with the second spherical surface 41. The second spherical surface 41 can be provided on the inner wall of the installation cavity 4.

In the structure provided in this embodiment, the movable member 3 can rotate relative to the installation cavity 4 in multiple directions due to the cooperative relationship between the first spherical surface 31 and the second spherical surface 41. This allows the mist outlet 321 to be oriented in different directions as the first spherical surface 31 rotates, enabling the spray device 1 to spray aerosols in various directions.

Optionally, at least a portion of the first spherical surface 31 is exposed to the outside of the spray device 1 through the through hole 211, with the mist outlet 321 being provided on the first spherical surface 31. This allows the mist outlet 321 to be oriented in different directions as the first spherical surface 31 rotates.

In a specific embodiment of the present disclosure, the movable member 3 can also include a control handle 34, which allows the user to rotate the movable member 3 via the control handle 34. Specifically, the control handle 34 is provided on the movable member 3 and exposed to the outside of the spray device 1 through the through hole 211.

In the structure provided in this embodiment, the exposed control handle 34 can be gripped or operated by the user, enabling the user to control the rotation of the movable member 3 and the mist outlet 321 to a desired position, thereby enhancing the usability of the spray device 1.

Further, the control handle 34 and the edge of the through hole 211 can also have an abutting relationship. This allows the control handle 34 to limit the rotation range of the movable member 3 to a certain extent, reducing the probability that the movable member 3 will rotate to an abnormal position so that the spraying device 1 will not work normally.

In a specific embodiment of the present disclosure, the upper cover 8 may have a limiting surface 42 formed in the installation cavity 4. Specifically, the limiting surface 42 may be formed on the inner wall of the installation cavity 4. When the movable member 3 is moved to a predetermined position, at least a portion of the movable member 3 is limited by the limiting surface 42.

Optionally, the limiting surface 42 may be formed at the bottom of the installation cavity 4. The lower end of the movable member 3 abuts against the limiting surface 42 at the bottom of the installation cavity 4, thereby limiting the rotation range of the movable member 3 and reducing the probability of the movable member 3 rotating to an abnormal position that may cause the spray device 1 to malfunction.

In addition, the movable member 3 may have a limiting edge 33. When the movable member 3 is rotated relative to the installation cavity 4 to a certain position, the limiting surface 42 abuts against the limiting edge 33, thereby limiting the rotation range of the movable member 3. This reduces the probability of the movable member 3 rotating to a misaligned position that may cause the spray device 1 to fail to function properly, thereby enhancing the stability of the spray device 1.

In a specific embodiment of the present disclosure, the movable member 3 may have an inlet 322 at an end of the mist channel 32 that is substantially opposite to the mist outlet 321. The device body 2 may also define a mist generation chamber 222. The device body 2 may include a connecting portion 51. The connecting portion 51 is located between the mist generation chamber 222 and the installation cavity 4, and is used to communicate the installation cavity 4 to the mist generation chamber 222. The inlet 322 can be connected to the connecting portion 51. The limiting edge 33 is provided on the movable member 3 around the inlet 322, and the limiting surface 42 is provided around the connecting portion 51.

In the structure provided in this embodiment, by providing the limiting surface 42 around the connecting portion 51 and allowing the inlet 322 where the limiting edge 33 is arranged to be connected to the connecting portion 51, the limiting surface 42 and the limiting edge 33 can limit the rotation of the movable member 3. This ensures that the mist generation chamber 222 can always communicate with the mist channel 32 via the connecting portion 51. During the rotation of the mist outlet 321 with the movable member 3, the aerosols generated in the spray device 1 can always enter the mist channel 32 via the connecting portion 51. When the mist outlet 321 is exposed, the aerosols can be smoothly discharged, thereby reducing the probability of the outflow of the aerosols being affected by the rotation of the movable member 3 and enhancing the usability of the spray device 1.

In a specific embodiment of the present disclosure, the mist outlet 321 may include at least one of an obround hole, a circular hole, or a polygonal hole.

Specifically, the mist outlet 321 may include an obround hole. The obround hole is elongated, which increases the radiation area of the aerosols when sprayed, thereby expanding the mist angle and enhancing the usability of the spray device 1. Furthermore, the obround hole may have a certain curvature, which can further increase the spray direction and expand the mist angle.

In a specific embodiment of the present disclosure, as the movable member 3 rotates, the mist outlet 321 can switch between states where it is not exposed through the through hole 211, partially exposed through the through hole 211, and fully exposed through the through hole 211.

In the structure provided in this embodiment, the device body 2 can shield the mist outlet 321 by controlling the rotation angle of the movable member 3. This allows the user to adjust the exposure degree of the mist outlet 321 to control the outflow effect of the mist channel 32 through the mist outlet 321, thereby enhancing the usability of the spray device 1. For example, when the aerosol generation rate in the device body 2 is stable, the size of the partially exposed mist outlet 321 is smaller than that of the fully exposed mist outlet 321. Therefore, the aerosols sprayed through the partially exposed mist outlet 321 are more concentrated and have a faster flow rate, while those sprayed through the fully exposed mist outlet 321 are more dispersed and have a slower flow rate. Different exposure degrees of the mist outlet 321 provide different outflow effects, allowing users to adjust the exposure degree of the mist outlet 321 according to their actual needs.

Moreover, when the spray device 1 is not in operation and not spraying aerosols, external pollutants such as dust and microorganisms may enter the interior of the spray device 1 through the mist outlet 321. If not properly handled, these pollutants can accumulate, potentially causing blockages in the mist generation chamber 222, reducing aerosol generation efficiency, and contaminating the aerosols produced. In particular, microorganisms may proliferate, which is not only difficult to clean but may also have adverse effects on the environment and human health when sprayed out with the aerosols.

By providing the structure described in this embodiment, the user can rotate the movable member 3 so that the mist outlet 321 is completely shielded by the device body 2 and not exposed through the through hole 211. This reduces the probability of external pollutants entering the spray device 1 through the mist channel 321 and affecting the aerosol generation process, thereby enhancing the stability and cleanliness of the spray device 1.

In a specific embodiment of the present disclosure, the upper cover 8 may include a cover plate 21 and a mounting component 5. The cover plate 21 is removably connected to the device body 2. The cover plate 21 and the mounting component 5 are also removably connected, with the installation cavity 4 being formed between the cover plate 21 and the mounting component 5.

Specifically, the device body 2 may also include a spray main body, with the mist generation chamber 222 being located within the spray main body. The mounting component 5 is connected to the spray main body, and the installation cavity 4 is formed between the mounting component 5 and the spray main body. The movable member 3 has an outer contour that is at least partially spherical, the through hole 211 is round hole, and the diameter of the through hole 211 is smaller than the maximum radial dimension of the movable member 3.

In a possible application, the outer contour of the movable member 3 may be in the shape of a spherical cap or other suitable shape. The spherical cap refers to the remaining part of a sphere after it is cut by a plane.

In the structure provided in this embodiment, the through hole 211 and the mounting component 5 can limit the spherical cap-shaped movable member 3, preventing the movable member 3 from falling out of the installation cavity 4 through the through hole 211.

Referring to FIGS. 5 to 8, FIG. 6 is a schematic structural view of the upper cover 8, the movable member, and the mounting component according to an embodiment of the present disclosure from another angle. FIG. 7 is a schematic sectional view of the upper cover 8, the movable member, and the mounting component in an assembled state according to an embodiment of the present disclosure. FIG. 8 is another sectional view of the upper cover 8, the movable member, and the mounting component in an assembled state according to an embodiment of the present disclosure from another angle.

In a specific embodiment of the present disclosure, the upper cover 8 may be removably connected to the device body 2.

Optionally, the mounting component 5 may include a first limiting structure and a first mating portion 53, while the cover plate 21 may include a second limiting structure and a second mating portion 23. The first mating portion 53 and the second mating portion 23 can be removably mated. The first mating portion 53 and the second mating portion 23 can be axially mated along the axial direction X and relatively rotated along the circumferential direction Y until the first limiting structure and the second limiting structure are engaged.

In the structure provided in this embodiment, the mounting component 5 utilize the first limiting structure and the first mating portion 53 to mate and removably engage with the second limiting structure and the second mating portion 23 of the cover plate 21. This connects the mounting component 5 to the cover plate 21, thereby limiting the movable member 3 within the installation cavity 4 formed between the mounting component 5 and the cover plate 21.

Specifically, the spray main body may also include a housing 22, which has a second opening 221. The through hole 211, the second mating portion 23, and the second limiting structure are provided on the cover plate 21. The installation cavity 4 is formed between the cover plate 21 and the mounting component 5. The cover plate 21 is mounted over the second opening 221. A mounting space 223 is defined between the cover plate 21 and the housing 22, with the mounting component 5 being located within the mounting space 223. The cover plate 21 has a first buckle groove 214, and the housing 22 is provided with a first buckle member 224 around the second opening 221. The first buckle member 224 can be removably engaged with the first buckle groove 214, thereby removably connecting the upper cover 8 to the housing 22.

As shown in FIGS. 4 and 7, the connecting portion 51 may have a protruding profile. This protruding connecting portion 51 is provided on the mounting component 5 and extends into the installation cavity 4. The limiting surface 42 is provided on the surface of the protruding connecting portion 51 facing the installation cavity 4. The connecting portion 51 has at least one connecting hole 511, which is used to communicate the mist generation chamber 222 to the mist channel 32. As the spherical cap-shaped movable member 3 rotates, the inlet 322 always surrounds the outer periphery of the connecting portion 51, allowing the aerosols entering the installation cavity 4 through the connecting hole 511 to pass into the mist channel 32.

In a specific embodiment of the present disclosure, the cover plate 21 and the mounting component 5 are connected in a swivel snap way, thereby enabling the installation of the movable member 3.

Specifically, one of the first limiting structure and the second limiting structure may include a limiting groove 52, while the other may include a limiting protrusion 212. The limiting groove 52 may include a guidance groove 521 and a buckle slot 522. One end of the guidance groove 521 communicates with the buckle slot 522. The guidance groove 521 extends along the axial direction X, while the buckle slot 522 extends along the circumferential direction Y. In a cross-section perpendicular to the axial direction X, the profile of the guidance groove 521 corresponds to the profile of the limiting protrusion 212. In a cross-section perpendicular to the circumferential direction Y, the profile of the buckle slot 522 corresponds to the profile of the limiting protrusion 212.

In the structure provided in this embodiment, the first mating portion 53 of the mounting component 5 can be axially mated with the second mating portion 23 of the cover plate 21. During this mating process, the limiting protrusion 212 also enters the guidance groove 521 along the axial direction X. Subsequently, the mounting component 5 and the cover plate 21 can be relatively rotated along the circumferential direction Y, causing the limiting protrusion 212 to move from the guidance groove 521 into the buckle slot 522. This enables the mounting component 5 and the cover plate 21 to be locked in the axial direction, thereby effectively limiting the movable member 3.

Further, as shown in FIG. 8, the upper side of the limiting protrusion 212 may have a buckle protrusion 213. The limiting groove 52 may also include an avoidance slot 523 and a mating groove 524. The avoidance slot 523 is provided at the bottom of the buckle slot 522, and the mating groove 524 corresponds to the buckle protrusion 213 and is provided on the upper side of the buckle slot 522.

When the limiting protrusion 212 moves along the circumferential direction Y into the buckle slot 522, surface of the buckle slot 522 presses against the buckle protrusion 213, causing the limiting protrusion 212 to deform towards the avoidance slot 523. When the buckle protrusion 213 aligns with the mating groove 524, the deformation of the limiting protrusion 212 recovers, moving it out of the avoidance slot 523. Through the setting of the buckle protrusion 213, the mating groove 524, and the avoidance slot 523, it is possible to utilize the snap-in relationship between the buckle protrusion 213 and the mating groove 524 in the circumferential direction Y to realize a position restriction, so as to enhance the stability of the connection between the cover plate 21 and the mounting component 5, and further reduce the probability of the movable member 3 falling out.

Optionally, the guidance groove 521, buckle slot 522, and limiting protrusion 212 are arranged in a circular manner. The cover plate 21 and the mounting component 5 can be relatively rotated. The circle, circumferential direction Y, first spherical surface 31, and second spherical surface 41 all have their centers aligned along the axial direction X.

The above description pertains to only some embodiments of the present disclosure and should not be construed as limiting the scope of the present disclosure. Any equivalent modifications and improvements made within the spirit and principles of the present disclosure are intended to be covered by the appended claims of the present disclosure.
