Humidifiers can increase indoor air humidity, making it more comfortable for users. In addition to their basic function of increasing humidity, humidifiers can also be used with fragrance oils, air fresheners, and other functional ingredients to provide users with a better experience.

[0003] Currently, the spray nozzles of most humidifiers are fixed, and users can only change the position and / or direction of the spray by moving the humidifier itself, which is very inconvenient. Utility Model Content

[0004] This application mainly provides a spraying device that can adjust the direction of the sprayed aerosol.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution: A spraying device is provided, comprising a device body, an upper cover, and a movable component.

[0030] With advancements in small household appliance technology, the problem of excessively dry indoor environments during autumn and winter has been addressed. Humidifiers can increase indoor air humidity, making it more comfortable for users. Beyond their basic function of increasing humidity, humidifiers can also be used with fragrance oils, air fresheners, and traditional Chinese medicine ingredients to spray a mist of water containing these ingredients into the air, achieving effects such as soothing the mind, treating ailments, and improving air quality, thus providing users with a better experience.

[0031] Most common humidifiers currently use a direct-spray nozzle design, where the water mist is sprayed in a fixed direction. This results in a very limited spray range, leading to uneven distribution of the sprayed mist and the presence of dead zones. Users typically have to move the humidifier itself to adjust the spray position and / or direction, which is quite inconvenient.

[0032] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.

[0033] See Figures 1 to 4 , Figure 1This is a schematic diagram of the assembly structure of the spray device provided in this application from one angle. Figure 2 This is a schematic diagram of the assembly structure of the spray device provided in this application from another angle. Figure 3 The spraying device provided in this application is in Figure 2 A schematic diagram of the cross-sectional structure at the angle shown. Figure 4 yes Figure 3 A partially enlarged structural diagram of region A. This application provides a spray device 1 for generating an aerosol and transporting it to the outside. The spray device 1 may include a main body 2, an upper cover, and a movable component 3.

[0034] The main body 2 of the device includes an aerosol generating chamber 222. An upper cover is connected to the main body 2 and includes a mounting cavity 4 and a through hole 211, the through hole 211 connecting to the mounting cavity 4. A movable component 3 is movably mounted in the mounting cavity 4 and is rotatable relative to the upper cover. The movable component 3 is provided with a mist outlet 321, which connects to the aerosol generating chamber 222. At least a portion of the movable component 3 is exposed in the mounting cavity 4 through the through hole 211. As the movable component 3 rotates, the mist outlet 321 faces different directions.

[0035] Specifically, the movable component 3 can rotate relative to the mounting cavity 4 in two directions. The movable component 3 may also be provided with a mist outlet 32, and the mist outlet 321 is connected to the mounting cavity 4 through the mist outlet 32.

[0036] In the structure provided in this embodiment, by rotatably installing the movable part 3 in the mounting cavity 4, and by exposing part of the movable part 3 through the through hole 211, the orientation of the mist outlet 321 provided on the movable part 3 can rotate with the rotation of the movable part 3. When the mist outlet 321 is rotated to be exposed through the through hole 211, the mist channel 32 can spray aerosol in different directions through the mist outlet 321, thereby achieving the effect of flexibly adjusting the orientation of the mist outlet 321. This allows the spraying device 1 to spray aerosol in multiple directions, thereby improving the usability of the spraying device 1.

[0037] In a specific embodiment of this application, the outer periphery of the movable part 3 may be provided with a first spherical surface 31, the outer contour of the movable part 3 may be at least partially spherical, and the inner wall of the mounting cavity 4 may be provided with a second spherical surface 41 corresponding to the first spherical surface 31, and the first spherical surface 31 can cooperate with the second spherical surface 41.

[0038] In the structure provided in this embodiment, by utilizing the cooperation relationship between the first spherical surface 31 and the second spherical surface 41, the movable part 3 can rotate relative to the mounting cavity 4 in multiple directions, so that the mist outlet 321 can rotate to face different directions as the first spherical surface 31 rotates, so that the spraying device 1 can spray aerosol in different directions using the mist outlet 321.

[0039] Optionally, at least a portion of the first spherical surface 31 may be exposed through the through hole 211, and the mist outlet 321 may be disposed on the first spherical surface 31 so that the mist outlet 321 may face different directions as the first spherical surface 31 rotates.

[0040] In one specific embodiment of this application, the movable member 3 may further include a toggle handle 34 to rotate the movable member 3. Specifically, the toggle handle 34 may be disposed on the movable member 3, and the toggle handle 34 may be exposed through the through hole 211.

[0041] With the structure provided in this specific embodiment, the exposed toggle handle 34 can be held or toggled by the user, allowing the user to control the movable part 3 to rotate the mist outlet 321 to the desired position, thereby improving the usability of the spray device 1.

[0042] Furthermore, the toggle handle 34 and the edge of the through hole 211 can also have a resisting relationship, thereby using the toggle handle 34 to limit the rotation range of the movable part 3, which can reduce the probability that the movable part 3 rotates to an abnormal position and causes the spraying device 1 to malfunction.

[0043] In one specific embodiment of this application, a limiting surface 42 may be provided inside the mounting cavity 4. Specifically, the limiting surface 42 may be formed inside the mounting cavity 4. When the movable member 3 moves to a set position, the movable member 3 is at least partially limited by the limiting surface 42.

[0044] Optionally, the limiting surface 42 can be formed at the bottom of the mounting cavity 4. The lower end of the movable member 3 can abut against the limiting surface 42 at the bottom of the mounting cavity 4, thereby limiting the rotation range of the movable member 3 and reducing the probability that the movable member 3 will rotate to an abnormal position and cause the spraying device 1 to malfunction.

[0045] Among them, the movable part 3 can be provided with a limiting edge 33. When the movable part 3 rotates to a certain position relative to the mounting cavity 4, the limiting surface 42 can abut against the limiting edge 33. Thus, the abutment relationship between the limiting surface 42 and the limiting edge 33 can be used to limit the range of rotation of the movable part 3, reduce the probability of the movable part 3 rotating to a misalignment, causing the spraying device 1 to malfunction, and improve the stability of the spraying device 1.

[0046] In one specific embodiment of this application, the end of the mist outlet channel 32 away from the mist outlet 321 may also be provided with an inlet 322, and the device body 2 may also be provided with an aerosol generating chamber 222. The device body 2 may include a connecting portion 51. The connecting portion 51 is disposed between the aerosol generating chamber 222 and the mounting chamber 4, and the connecting portion 51 can be used to connect the mounting chamber 4 and the aerosol generating chamber 222. The inlet 322 can be connected to the connecting portion 51, and a limiting edge 33 is provided on the movable member 3 around the inlet 322, and a limiting surface 42 is provided on the periphery of the connecting portion 51.

[0047] In the structure provided in this specific embodiment, by setting the limiting surface 42 on the periphery of the connecting part 51, and connecting the inlet 322 where the limiting edge 33 is located to the connecting part 51, the limiting relationship between the limiting surface 42 and the limiting edge 33 is utilized to ensure that the aerosol generating chamber 222 is always connected to the mist outlet channel 32 through the connecting part 51 and the inlet 322. This allows the aerosol generated in the spray device 1 to always enter the mist outlet channel 32 through the connecting part 51 as the moving part 3 rotates. When the mist outlet 321 is exposed, the aerosol discharge effect can be maintained smoothly, thereby reducing the probability that the rotation of the moving part 3 will affect the misting effect and improving the usability of the spray device 1.

[0048] In one specific embodiment of this application, the mist outlet 321 may include at least one of an oblong hole, a circular hole, and a polygonal hole.

[0049] The mist outlet 321 may specifically include an oblong orifice. The oblong orifice is elongated, which increases the radiation area of ​​the aerosol during spraying, thereby expanding the range of mist exit angles and improving the usability of the spray device 1. Furthermore, the oblong orifice may also have a certain curvature, which can further increase the direction of mist exit and expand the range of mist exit angles.

[0050] In one specific embodiment of this application, as the movable part 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 completely exposed through the through hole 211.

[0051] In the structure provided in this specific embodiment, the movable member 3 can shield the mist outlet 321 using the main body 2 of the device. The degree of exposure of the mist outlet 321 can be controlled by controlling the rotation angle of the movable member 3, thereby controlling the misting effect of the misting channel 32 through the mist outlet 321 to the outside, and improving the usability of the spraying device 1. For example, when the aerosol generation rate inside the main body 2 is stable, the size of the mist outlet 321 when it is partially exposed is smaller than the size when it is fully exposed. Therefore, the aerosol sprayed through the partially exposed mist outlet 321 will be more concentrated and faster, while the aerosol sprayed through the fully exposed mist outlet 321 will be more dispersed and slower. The mist outlet 321 with different degrees of exposure has different misting effects, and the user can adjust the degree of exposure of the mist outlet 321 according to actual needs.

[0052] Furthermore, when the spray device 1 is not in operation and is not emitting mist, external pollutants such as dust and microorganisms may enter the interior of the spray device 1 through the mist outlet 321. If not specifically treated, they can easily accumulate inside, potentially causing problems such as blockage of the aerosol generation chamber 222, decreased aerosol generation efficiency, and contamination of the generated aerosols. Microorganisms, in particular, may multiply within the aerosols, making them not only difficult to clean but also potentially causing adverse effects on the environment and the health of users when sprayed out with the aerosols.

[0053] With the structure provided in this specific embodiment, the mist outlet 321 can be completely blocked from being exposed through the through hole 211 by rotating the movable part 3. The mist outlet channel 32 can be closed by the main body 2 of the device, thereby reducing the probability that external pollutants will enter the interior of the spray device 1 through the mist outlet channel 32 and affect the aerosol generation process, thus improving the stability and cleanliness of the spray device 1.

[0054] In one specific embodiment of this application, the upper cover may include a cover plate 21 and a mounting member 5, wherein the cover plate 21 is detachably connected to the device body 2. The cover plate 21 and the mounting member 5 are detachably connected, and a mounting cavity 4 is formed between the cover plate 21 and the mounting member 5.

[0055] Specifically, the main body 2 may also include a spray body, and an aerosol generating chamber 222 may be disposed within the spray body. The mounting member 5 may be connected to the spray body, and a mounting cavity 4 is formed between the mounting member 5 and the spray body. The outer contour of the movable member 3 is at least partially spherical, and the diameter of the through hole 211 is smaller than the radial dimension of the movable member 3.

[0056] In possible applications, the outer contour of the movable part 3 can be in a suitable shape, such as a spherical crown. Here, a spherical crown refers to the portion remaining after a portion of the first spherical surface has been removed by a plane.

[0057] The structure provided in this specific embodiment enables the through hole 211 and the mounting member 5 to limit the spherical crown-shaped movable member 3, thereby preventing the movable member 3 from falling out of the mounting cavity 4 through the through hole 211.

[0058] See Figures 5 to 8 , Figure 5 This is a structural schematic diagram of the upper cover, movable parts, and mounting parts in this application. Figure 6 This is a structural schematic diagram of the upper cover, movable parts, and mounting parts from another angle in this application. Figure 7 This is a cross-sectional structural diagram of the upper cover, movable parts, and mounting parts during assembly in this application. Figure 8 This is another cross-sectional structural diagram of the assembly of the upper cover, movable parts, and mounting parts in this application.

[0059] In one specific embodiment of this application, the upper cover is detachably connected to the device body 2.

[0060] Optionally, the mounting component 5 may include a first limiting structure and a first sleeve portion 53, and the upper cover may include a second limiting structure and a second sleeve portion 23. The first sleeve portion 53 and the second sleeve portion 23 are detachably sleeved together. The first sleeve portion 53 and the second sleeve portion 23 are sleeved together along the axial direction X and can rotate relative to each other along the circumferential direction Y until the first limiting structure and the second limiting structure are engaged.

[0061] With the structure provided in this specific embodiment, the mounting member 5 can be sleeved and detachably snapped with the second limiting structure and the second sleeve 23 of the spray body using the first limiting structure and the first sleeve 53, thereby connecting the mounting member 5 to the spray body, and thus confining the movable member 3 in the mounting cavity 4 between the mounting member 5 and the spray body.

[0062] Specifically, the spray body may further include a housing 22, which has a second opening 221, a through hole 211, a second sleeve portion 23, and a second limiting structure disposed on the cover plate 21. An installation cavity 4 is disposed between the cover plate 21 and the mounting member 5, with the cover plate 21 covering the second opening 221. An installation space 223 is formed between the cover plate 21 and the housing 22, and the mounting member 5 is disposed within the installation space 223. The cover plate 21 has a first snap-fit ​​groove 214, and the housing 22 around the second opening 221 has a first snap-fit ​​member 224. The first snap-fit ​​member 224 is detachably connected to the first snap-fit ​​groove 214, thereby detachably connecting the cover and the housing 22.

[0063] like Figure 4 , Figure 7As shown, the outline shape of the connecting part 51 can specifically be a boss-shaped shape. This boss-shaped connecting part 51 is provided on the mounting member 5 and protrudes into the mounting cavity 4. The limiting surface 42 is provided on the side surface of the boss-shaped connecting part 51 facing into the mounting cavity 4. The connecting part 51 is provided with at least one connecting hole 511, which is used to connect the aerosol generating chamber 222 and the mist outlet channel 32. As the spherical cap-shaped movable member 3 rotates, the inlet 322 is always fitted around the outer periphery of the boss-shaped connecting part 51, so that the aerosol entering the mounting cavity 4 through the connecting hole 511 can enter the mist outlet channel 32.

[0064] In one specific embodiment of this application, the cover plate 21 and the mounting member 5 can be rotatably snapped together, thereby enabling the installation of the movable member 3.

[0065] Specifically, one of the first and second limiting structures may include a limiting groove 52, and the other may include a limiting protrusion 212. The limiting groove 52 may include a guide groove 521 and a snap-fit ​​groove 522. One end of the guide groove 521 is connected to the snap-fit ​​groove 522. The guide groove 521 is arranged along the axial direction X, and the snap-fit ​​groove 522 is arranged along the circumferential direction Y. In a cross-section perpendicular to the axial direction X, the contour shape of the guide groove 521 corresponds to the contour shape of the limiting protrusion 212. In a cross-section perpendicular to the circumferential direction Y, the contour shape of the snap-fit ​​groove 522 corresponds to the contour shape of the limiting protrusion 212.

[0066] With the structure provided in this specific embodiment, the first sleeve portion 53 of the mounting member 5 can be sleeved with the second sleeve portion 23 of the cover plate 21 along the axial direction X. At the same time as the first sleeve portion 53 and the second sleeve portion 23 are engaged, the limiting protrusion 212 will also enter the guide groove 521 along the axial direction X. Then, the mounting member 5 and the cover plate 21 can be rotated relative to each other along the circumferential direction Y, so that the limiting protrusion 212 enters the snap-fit ​​groove 522 from the guide groove 521. The mounting member 5 and the cover plate 21 can be snapped and locked in the direction parallel to the axial direction, thereby achieving effective limiting of the movable member 3.

[0067] Furthermore, such as Figure 8 As shown, the upper surface of the limiting protrusion 212 may be provided with a snap-fit ​​protrusion 213, and the limiting groove 52 may also include a clearance groove 523 and an adapter groove 524. The clearance groove 523 is disposed at the bottom of the snap-fit ​​groove 522, and the adapter groove 524 is disposed on the upper surface of the snap-fit ​​groove 522 corresponding to the snap-fit ​​protrusion 213.

[0068] When the limiting protrusion 212 moves into the snap-fit ​​groove 522 along the circumferential Y direction, the snap-fit ​​groove 522 abuts against the snap-fit ​​protrusion 213, causing the limiting protrusion 212 to deform to a certain extent towards the clearance groove 523. When the snap-fit ​​protrusion 213 mates with the adapter groove 524, the deformation of the limiting protrusion 212 returns to its original state and leaves the clearance groove 523. Through the setting of the snap-fit ​​protrusion 213, the adapter groove 524, and the clearance groove 523, the snap-fit ​​relationship between the snap-fit ​​protrusion 213 and the adapter groove 524 can be used to limit the movement in the circumferential Y direction, thereby improving the stability of the connection between the cover plate 21 and the mounting part 5, and further reducing the probability of the moving part 3 falling out.

[0069] Optionally, the guide groove 521, the snap-fit ​​groove 522, and the limiting protrusion 212 are arranged around the circumference, and the cover plate 21 and the mounting part 5 can rotate relative to each other. The center of the circumference, the circumferential direction Y, the first spherical surface 31, and the second spherical surface 41 are arranged on the straight line where the axial direction X is located.

[0070] The above description is only a partial embodiment of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the scope of patent protection of this application.
