[0030] The following is for reference. Figures 1 to 3A spraying device according to an embodiment of the present invention will be described in detail.

[0031] refer to Figure 1 and Figure 2 According to an embodiment of the present invention, a spraying device includes a housing 100, a sprayer 200, a pressing module 300, and a detection module 400. The sprayer 200 is disposed inside the housing 100. The pressing module 300 is disposed inside the housing 100 and is drivenly connected to the nozzle 210 of the sprayer 200. The pressing module 300 can press the nozzle 210 to make the sprayer 200 spray into a spraying area outside the housing 100. The detection module 400 is disposed on the housing 100 and is electrically connected to the pressing module 300. The detection module 400 can control the pressing module 300 to release the nozzle 210 when a human body is detected in the spraying area.

[0032] In a spraying device according to this embodiment, when the detection module 400 detects that there is no human body in the spraying area, the pressing module 300 can press the nozzle 210 of the sprayer 200 to make the sprayer 200 spray into the spraying area; when the detection module 400 detects that there is a human body in the spraying area, the detection module 400 transmits information to the pressing module 300, thereby controlling the pressing module 300 to release the nozzle 210 to prevent the sprayer 200 from spraying into the spraying area. From the above, it can be seen that the spraying device of this application, by setting the detection module 400 to detect whether a human body is present in the spraying area, can effectively reduce the possibility of accidentally spraying people into the spraying area, thereby improving the user experience.

[0033] refer to Figure 2 and Figure 3 In some embodiments of this utility model, the pressing module 300 includes a driving assembly 310 and a pressing member 320. The pressing member 320 is rotatably disposed and abuts against the nozzle 210. The driving assembly 310 is drivenly connected to the pressing member 320 and is used to drive the pressing member 320 to rotate forward or backward, so that the pressing member 320 can press or release the nozzle 210. It can be understood that by driving the pressing member 320 to rotate forward by the driving assembly 310, the pressing member 320 can press the nozzle 210 it abuts against, thereby enabling the sprayer 200 to spray into the spray area; by driving the pressing member 320 to rotate backward by the driving assembly 310, the pressing member 320 moves away from and releases the nozzle 210, thereby enabling the sprayer 200 to stop spraying into the spray area.

[0034] It is understandable that by driving the pressing component 320 to rotate through the driving component 310 to press the nozzle 210, the pressing component 320 occupies less space during rotation, thus making the overall spatial structure of the spraying device more compact.

[0035] like Figure 3As shown, in some embodiments, the drive assembly 310 includes a motor 311 and a reduction gear set 312. The output end of the motor 311 is drivenly connected to the input gear 312a of the reduction gear set 312, and the output gear 312b of the reduction gear set 312 is drivenly connected to the pressing member 320. It is understood that the motor 311 is connected to the pressing member 320 through the reduction gear set 312. When the motor 311 is at a certain power, it can output more torque to the pressing member 320 through the reduction gear set 312, allowing the pressing member 320 to rotate a greater distance at a given power, making it easier to press the nozzle 210.

[0036] refer to Figure 3 In one embodiment, the pressing member 320 has meshing teeth 321 on its circumference that mesh with the output gear 312b. It is understood that the pressing member 320 meshes with the output gear 312b via its circumferential meshing teeth 321, rather than being coaxially arranged with the output gear 312b. This reduces the space occupied by the pressing member 320 and the drive assembly 310 in the axial direction of the output gear 312b, thereby eliminating the need for the spraying device to adjust its structure in the axial direction of the output gear 312b to provide space for the pressing member 320.

[0037] refer to Figure 2 In one embodiment, the drive assembly 310 further includes a mounting bracket 313. The nozzle 210 has a vertically extending elongated hole 211, and the mounting bracket 313 has an insertion portion 313a that slidably passes through the elongated hole 211. It is understood that when the pressing member 320 rotates forward or in the opposite direction under the drive assembly 310, the nozzle 210 moves vertically under the action of the pressing member 320, causing the insertion portion 313a on the mounting bracket 313 to slide within the elongated hole 211. Through the cooperation of the insertion portion 313a and the vertically extending elongated hole 211, the possibility of the nozzle 210 deviating from its movement path during vertical movement is reduced, thereby ensuring that the distance by which the pressing member 320 drives the nozzle 210 to move downward remains unchanged when the pressing member 320 rotates forward by a certain angle.

[0038] In a further embodiment of the present invention, the mounting bracket 313 is provided with two interpenetrating portions 313a at intervals along the horizontal direction, and the nozzle 210 is provided with two elongated holes 211 extending along the vertical direction. The two interpenetrating portions 313a are respectively slidably inserted into the two elongated holes 211.

[0039] refer to Figure 1 and Figure 2In some embodiments of this utility model, the housing 100 includes a first housing cover 110 and a second housing cover 120 that are detachably connected. The first housing cover 110 and the second housing cover 120 together define a receiving cavity. The sprayer 200 is detachably disposed within the receiving cavity. The cavity wall of the receiving cavity is provided with a spray port 121 communicating with the outside, and the nozzle 210 is directly opposite the spray port 121. It is understood that when it is necessary to replenish the liquid in the sprayer 200, the first housing cover 110 and the second housing cover 120 are separated, the sprayer 200 is then separated from the receiving cavity, liquid is re-injected into the sprayer 200, and then the sprayer 200 is placed back into the receiving cavity, with the first housing cover 110 and the second housing cover 120 connected, thereby completing the replenishment of the liquid in the sprayer 200. By making the first housing cover 110 and the second housing cover 120 detachable, and the sprayer 200 detachably disposed within the receiving cavity, it is more convenient to replace or replenish the liquid in the sprayer 200.

[0040] refer to Figure 2 In some embodiments, the first cover 110 is provided with a snap-fit ​​structure 111, and the second cover 120 is provided with a snap-fit ​​hole 122. The snap-fit ​​structure 111 is at least partially snapped into the snap-fit ​​hole 122 to prevent the first cover 110 and the second cover 120 from separating. It is understood that when the snap-fit ​​structure 111 disengages from the snap-fit ​​hole 122, the first cover 110 can be separated from the second cover 120; by snapping the snap-fit ​​structure 111 into the snap-fit ​​hole 122, the first cover 110 and the second cover 120 are difficult to separate, thus achieving a fixed connection between the first cover 110 and the second cover 120.

[0041] like Figure 2 As shown, in one embodiment, the snap-fit ​​structure 111 includes a snap-fit ​​portion 111a and an elastic portion 111b. The snap-fit ​​portion 111a is connected to the first cover 110 through the elastic portion 111b. The snap-fit ​​portion 111a snaps into the snap-fit ​​hole 122. The elastic portion 111b is used to provide a spring force to prevent the snap-fit ​​portion 111a from disengaging from the snap-fit ​​hole 122. Under the action of external force, the snap-fit ​​portion 111a can overcome the spring force of the elastic portion 111b to disengage from the snap-fit ​​hole 122. Understandably, by pressing the locking part 111a of the locking structure 111, the locking part 111a overcomes the elastic force of the elastic part 111b and disengages from the locking hole 122, at which point the user can separate the first cover 110 from the second cover 120; when the user removes the force applied to the locking part 111a, the locking part 111a can re-engage with the locking hole 122 under the action of the elastic part 111b, thereby achieving a quick connection between the first cover 110 and the second cover 120.

[0042] refer to Figure 1 and Figure 2In some embodiments, the detection module 400 includes an infrared sensor positioned above the spray nozzle 121. It is understood that by positioning the infrared sensor above, when the infrared sensor detects a human body, the spray nozzle 121 is more likely to be blocked by the body, thereby improving the accuracy of the detection results of the detection module 400 and reducing the possibility of the spray nozzle 121 being detected by the infrared sensor even when it is not blocked, thus improving the user experience.

[0043] refer to Figure 2 In some embodiments of this utility model, the sprayer 200 further includes a storage bottle 220, which has a storage cavity for storing the liquid to be sprayed. The nozzle 210 is detachably disposed at the mouth of the storage bottle 220 and communicates with the storage cavity. It is understood that by detaching the nozzle 210 and the storage bottle 220, when it is necessary to replenish the liquid in the storage bottle 220, the user can simply remove the storage bottle 220 from the nozzle 210 and then add the liquid to the storage cavity in the storage bottle 220, without having to separate the entire sprayer 200 from the receiving cavity.

[0044] In some embodiments of this utility model, the spraying device further includes a control board, which is electrically connected to the pressing module 300. The control board is provided with a time setting push button and a manual spraying button. By moving the time setting push button, the interval time of pressing the nozzle 210 by the pressing module 300 can be adjusted by the control board.

[0045] In some embodiments of this utility model, a manual spray button is provided on the control panel. By pressing the manual spray button, the control panel can control the pressing module 300 to press the nozzle 210. It can be understood that when the user needs to spray manually, they can directly spray by pressing the manual spray button.

[0046] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
