Description

Technical Field

[0001] This utility model relates to the field of automatic liquid dispensing technology for cleaning agents, and in particular to a pump mechanism for an automatic liquid dispenser. Background Technology

[0002] In existing technologies, disinfectants or cleaning agents are provided on cleaning stations in large supermarkets and hospitals. These are dispensed by pressing a pump on a cosmetic bottle. However, since the pump is directly touched by hand, especially during flu season, germs or bacteria can easily remain on the pump, potentially causing cross-infection. Furthermore, children have limited strength and find it difficult to manually press the pump to dispense the disinfectant or cleaning agent.

[0003] Therefore, it is necessary to design a device that can automatically sense and pressurize the pump to assist in liquid collection and avoid cross-infection. Utility Model Content

[0004] The purpose of this invention is to provide a pump mechanism for an automatic liquid dispenser, solving the problem of how to automatically sense and pump the cleaning agent pump head.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides a pump mechanism for an automatic liquid dispenser, including a support, a photoelectric sensor disposed on the top of the support, and an electrically controlled pressing mechanism;

[0007] The electrically controlled pressing mechanism includes a guide cylinder disposed on the top of the support, a sleeve disposed on the outer periphery of the guide cylinder, a coil disposed in the sleeve, and a magnetically controlled pressing block disposed inside the guide cylinder.

[0008] The coil is a threaded coil that surrounds the outside of the guide cylinder. The two ends of the coil are respectively connected to a controller and a power supply through wires. The detection signal of the photoelectric sensor is transmitted to the controller through a signal transmission line.

[0009] The guide cylinder is a hollow cylindrical structure with an open bottom, the magnetron pressure block is made of magnetic material, and the top of the magnetron pressure block is connected to the inner top of the guide cylinder by a return spring.

[0010] In a further embodiment, the support includes a base plate, a top plate, and two side plates that are vertically connected to the base plate and the top plate;

[0011] A circular groove is provided on the base plate to limit the movement of the cleaning agent bottle, and the circular groove is located directly below the magnetic pressure block;

[0012] Guide rails are symmetrically arranged on the two side plates; a clamping plate for positioning the pump head on the cleaning agent bottle is inserted into the guide rails.

[0013] In a further embodiment, the guide rail is a horizontal groove or an inclined groove with an inclination of 5°-10° to facilitate the insertion of the card plate.

[0014] In a further embodiment, the card plate includes two separate card plates, each with a card slot. A fastener is symmetrically arranged on the horizontal sidewall of one of the separate card plates, and a plug hole adapted to the fastener is provided in the other separate card plate.

[0015] Furthermore, in this embodiment, the bottom of the magnetically controlled pressure block is provided with a rubber pad for squeezing the pump head.

[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0017] In this invention, the photoelectric sensor is used to detect the position of the user's hand. The detection information of the photoelectric sensor is then sent to the controller. Then, the magnetic field generated at the center of the coil after it is energized pushes out the magnetic control block in the guide cylinder, and the bottom end of the block squeezes the pump head to spray the cleaning agent in the cleaning agent bottle onto the user's hand, thus completing the automatic liquid dispensing and avoiding cross-infection caused by pressing with hands.

[0025] refer to Figure 1 and Figure 4 This embodiment provides a pump mechanism for an automatic liquid dispenser, including a support 1, a photoelectric sensor 7 mounted on the top of the support 1, and an electrically controlled pressing mechanism. The support 1 includes a base plate, a top plate, and two side plates vertically connecting the base plate and the top plate; a circular groove is provided on the base plate to limit the positioning of the cleaning agent bottle 8, the circular groove being located directly below the magnetically controlled pressing block 31; guide rails 11 are symmetrically mounted on the two side plates; a clamping plate 2 for positioning the pressing pump head 81 on the cleaning agent bottle 8 is inserted into the guide rail 11; the photoelectric sensor 7 is a through-beam photoelectric sensor, which transmits hand position information to the controller when the user blocks the photoelectric sensor 7 with their hand.

[0026] When in use, when the user brings their hand close to the pump head 81, the photoelectric sensor 7 can detect the position of the hand, thereby triggering the electronically controlled pressing mechanism to press down the pump head 81 to pump out the required cleaning agent.

[0027] In this embodiment, the guide rail 11 is a horizontal groove or an inclined groove with an inclination of 5°-10° to facilitate the insertion of the card plate 2, wherein the card plate 2 inserted into the guide rail 11 is limited.

[0028] refer to Figure 2 The card plate 2 includes two separate card plates, each with a card slot 21. A fastener 23 is symmetrically and vertically installed on the horizontal side wall of one of the separate card plates, and a insertion hole 22 adapted to the fastener 23 is provided in the other separate card plate. The cleaning agent bottle 8 and the pump head 81 on it are limited by the card slot 21 aligned on the card plate 2, and then inserted into the inclined slide groove of the guide rail 11 through the card plate 2. In this embodiment, the inner diameter of the insertion hole 22 is not less than the maximum outer diameter of the fastener 23, and the fastener 23 and the insertion hole 22 are designed to be staggered to facilitate disassembly or assembly.

[0029] refer to Figure 4 and Figure 5The electrically controlled pressing mechanism includes a guide cylinder 3 installed on the top of the support 1, a sleeve 33 installed on the outer periphery of the guide cylinder 3, a coil 6 installed in the sleeve 33, and a magnetically controlled pressing block 31 installed inside the guide cylinder 3; wherein the bottom of the magnetically controlled pressing block 31 is equipped with a rubber pad for squeezing the pressing pump head 81.

[0030] The coil 6 is a threaded coil that surrounds the outside of the guide cylinder 3. The two ends of the coil 6 are connected to the controller 5 and the power supply 4 respectively through wires 41. The detection signal of the photoelectric sensor 7 is transmitted to the controller 5 through a signal transmission line. The guide cylinder 3 is a hollow cylindrical structure with an open bottom. The magnetic control block 31 is made of magnetic material. The top of the magnetic control block 31 is connected to the inner top of the guide cylinder 3 through a reset spring 32.

[0031] In use, the photoelectric sensor 7 can also be replaced with an ultrasonic sensor. The photoelectric sensor 7 or the ultrasonic sensor detects the position of the user's hand, and then sends the detection information of the photoelectric sensor 7 or the ultrasonic sensor to the controller, thereby turning on the power to the coil 6. Then, the magnetic field generated at the center of the coil 6 after it is energized pushes out the magnetic control block 31 in the guide cylinder 3, and makes its lowest end squeeze the press pump head 81 to spray the cleaning agent in the cleaning agent bottle 8 onto the user's hand, completing the automatic liquid dispensing and avoiding cross-infection caused by pressing with hands.
