[0035] The following is combined with Figure 1 To Attachment Figure 5 , the embodiments of the present application are further described.

[0036] Reference Figure 1 and Figure 2The present application provides a hanging soap dispenser, which is mainly hung in bathrooms, kitchens, public places and the like, and can automatically dispense hand soap through induction. The body of the soap dispenser is composed of a soap bottle 100 and a lower shell 200. Specifically, at least one liquid storage chamber 110 is provided inside the soap bottle 100. In the present embodiment, a partition is provided inside the soap bottle 100 to divide the internal space of the soap bottle 100 into two liquid storage chambers 110, which can be used to store different soap liquids or foam liquids. The upper opening of the liquid storage chamber 110 serves as a liquid filling port for adding soap liquid therein. The lower shell 200 is provided below the soap bottle 100, and the lower shell 200 is used to accommodate various functional accessories on the soap dispenser.

[0037] like Figure 2 As shown, the lower part of the soap bottle 100 is connected to a liquid outlet assembly 400, and the liquid outlet assembly 400 is located inside the lower housing 200. Figure 3 As shown, the liquid outlet assembly 400 includes a driving pump 410, an electromagnetic valve 420, a liquid outlet pipe 430, and a liquid outlet nozzle 440. The driving pump 410 is provided with a motor (not shown in the figure) to drive the driving pump 410. Figure 3 and Figure 4 In this embodiment, a gear pump is used as the driving pump 410. The upper part of the driving pump 410 is connected to the liquid storage chamber 110 through the feed pipe 411. A gear driven by a motor is arranged in the driving pump 410. When the gear rotates, the liquid is driven to flow and the hand sanitizer is output. In order to solve the problem of dripping when the gear pump is not working, the electromagnetic valve 420 is arranged at the outlet of the driving pump 410 in this design. At the same time, the liquid outlet nozzle 440 is connected to the outlet of the driving pump 410 through the liquid outlet pipe 430, and the liquid outlet nozzle 440 is arranged downward. Specifically, the electromagnetic valve 420 includes an electromagnetic coil 422 and a plunger 421. The plunger 421 is arranged to block the outlet of the driving pump 410 to prevent dripping. When the electromagnetic coil 422 is energized, it drives the plunger 421 to retreat to open the outlet of the driving pump 410. When the electromagnetic coil 422 is powered off, the plunger 421 is reset. In order to ensure the reliability of the plugging of the plunger 421, the plunger 421 is set as a drum-shaped shaft, and a flexible rubber layer 423 is set outside the plunger 421. When the plunger 421 plays a plugging role, the flexible rubber layer 423 can improve its sealing. Further, the electromagnetic valve 420 is provided with an elastic element that drives the plunger 421 to reset, and the elastic element is preferably a spring.

[0038] A control component is also provided in the lower housing 200, and the control component includes a sensor, a wire and a controller. The sensor is located at the periphery of the liquid outlet nozzle 440, and the sensor and the controller are connected by a wire. The controller is also connected to the drive pump 410 and the electromagnetic valve 420. After the sensor senses that the object to be cleaned appears below the liquid outlet nozzle 440, the controller controls the drive pump 410 to pump out the soap liquid, and the controller synchronously controls the electromagnetic valve 420 to operate. After the electromagnetic valve 420 is energized, the plunger 421 retreats to open the outlet of the drive pump 410, so that the soap liquid can flow out through the liquid outlet pipe 430 and the liquid outlet nozzle 440; when the drive pump 410 stops working, the controller controls the electromagnetic valve 420 to power off and reset, and the plunger 421 is reset to block the outlet of the drive pump 410 to prevent the soap liquid from flowing out.

[0039] Further, such as Figure 1 and Figure 2 As shown, a top cover 300 is provided on the upper part of the soap liquid bottle 100, and the top cover 300 is used to cover the liquid filling port. When used in a public place, in order to prevent the top cover 300 from being opened by unrelated persons, a lock 310 is preferably provided on the top cover 300, and a corresponding key 320 is configured. When the top cover 300 is closed, the key 320 is used to drive the lock 310 to move, and the top cover 300 is locked on the soap liquid bottle 100, so that it cannot be opened by others; when it is necessary to add soap liquid into the soap liquid bottle 100, the key 320 is used to drive the lock 310 to move in the opposite direction to open the top cover 300.

[0040] Further, see Figure 1 and Figure 2 A switch button 210 is provided on the lower shell 200, and the switch button 210 is connected to the controller. When a person long presses the switch button 210, the soap dispenser is started. After being started, the soap dispenser is in a standby state. When the sensor senses that there is an object to be cleaned under the liquid outlet 440, the driving pump 410 and the electromagnetic valve 420 of the soap dispenser will be activated to pump out a fixed amount of soap for people to wash; when a person long presses the switch button 210 again, the soap dispenser is turned off. After being turned off, the soap dispenser will not automatically pump out soap to facilitate maintenance.

[0041] Furthermore, a power module is provided in the lower housing 200, and the power module provides working current for the motor, electromagnetic valve 420 in the liquid outlet component and the sensor and controller in the control component. In this embodiment, the power module is configured to be rechargeable, and a charging interface 220 is provided on the lower housing 200, such as Figure 1 and Figure 2 In addition, it is easy to understand that in other embodiments, the power module can also use a replaceable battery.

[0042] like Figure 2 and Figure 5As shown, the soap dispenser of this embodiment further includes a wall plate 500. The wall plate 500 can be arranged on the back of the soap bottle 100 or the lower shell 200. In this embodiment, the wall plate 500 is preferably arranged on the back of the lower shell 200. A plurality of bolt holes 510 are arranged on the side of the wall plate 500 facing the wall, and bolts passing through the bolt holes 510 can fix the wall plate 500 on the wall or the cabinet wall. The wall plate 500 has convex ribs 520 on both sides, and the lower shell 200 is provided with a plug-in slot 230 that matches the convex ribs 520. When the wall plate 500 is fixed on the wall or the cabinet wall, the plug-in slot 230 of the lower shell 200 is aligned with the wall plate 500 and inserted, and the soap dispenser can be hung on the wall or the cabinet wall. Of course, it is easy to think that the positions of the plug-in slot 230 and the rib 520 can also be interchanged, that is, a plug-in slot 230 is provided on the wall hanging plate 500, and a rib 520 matching the plug-in slot 230 is provided on the soap liquid bottle 100 or the lower shell 200, which can also realize the quick plug-in and fixation of the wall hanging plate 500 and the soap liquid machine.

[0043] Further, see Figure 5 In order to improve the reliability of the connection between the wall plate 500 and the soap dispenser, in this embodiment, a horizontally protruding mounting member 530 is provided on the wall plate 500, and a through hole is provided on the mounting member 530. A mounting hole 240 is provided at the bottom of the lower housing 200 of the soap dispenser. The position of the mounting hole 240 matches the through hole on the mounting member 530, and the mounting hole 240 is a screw hole. When the soap dispenser is inserted into the wall plate 500, a bolt can be used to pass through the through hole on the mounting member 530 to connect to the mounting hole 240, thereby further enhancing the reliability of the connection between the wall plate 500 and the soap dispenser.

[0044] Furthermore, the circular channel is prone to form large bubbles, which will affect the operation of the driving pump 410 when they fall into it. In order to prevent this situation, in the present embodiment, the cross-sectional shape of the feed pipe 411 is set to be non-circular. Specifically, the cross-sectional shape of the inner diameter of the feed pipe 411 can be D-shaped, triangular, square, or the like.

[0045] Furthermore, in this embodiment, the gears in the driving pump 410 are helical gears. Compared with spur gears, helical gears are used as the main components in the driving pump 410, so that the driving pump 410 has the advantages of low noise, smooth liquid discharge, and good liquid discharge ratio when operating.

[0046] The soap dispenser of the present application adopts a gear pump as a driving pump 410. The gear pump has the advantages of small size and continuous liquid discharge. In order to solve the problem of liquid dripping in the gear pump, the present design sets an electromagnetic valve 420 at the outlet of the gear pump. The electromagnetic valve 420 and the gear pump are controlled by a controller to act synchronously. When the gear pump is working, the electromagnetic valve 420 also acts to keep the liquid outlet channel open, allowing the soap liquid to flow out smoothly. When the gear pump is on standby, the electromagnetic valve 420 resets and closes the outlet of the gear pump to avoid liquid dripping. The soap dispenser of the present application adopts a combination of a gear pump and an electromagnetic valve 420, which effectively reduces the size of the soap dispenser and reduces costs. At the same time, it can achieve continuous liquid discharge and improve the user experience.

[0047] The above is a specific description of the preferred implementation of the present application, but the present application is not limited to the above implementation mode. Technical personnel familiar with the field can also make various equivalent modifications or substitutions under the shared conditions without violating the spirit of the present application. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
