[0002] With increasing awareness of personal hygiene and health, hand sanitizer dispensers, as non-contact automatic dispensing devices, are widely used in homes, offices, medical institutions, and public health areas. Existing hand sanitizer dispensers typically use an electric pump combined with a sensor-controlled circuit to automatically dispensing liquid or foam, offering better convenience and hygiene compared to traditional pump-type soap dispensers.

[0023] like Figures 1 to 5 As shown, a hand sanitizer dispenser includes a body assembly 10 and a liquid storage bottle 20. The liquid storage bottle 20 is detachably connected to the lower part of the body assembly 10. In use, the user injects hand sanitizer into the liquid storage bottle 20 and assembles it into the lower part of the body assembly 10.

[0024] In practical implementation, the main body component 10 includes a mounting housing 11, inside which a foaming pump 12, a motor 13, a battery 14, and a countersunk head 15 are respectively installed. The motor 13 is located at the upper end of the foaming pump 12 to drive it and generate pressure. The battery 14 and the countersunk head 15 are respectively located on the side of the foaming pump 12. The battery 14 provides power to the entire unit, and the countersunk head 14 is used to mix hand sanitizer and air to complete the foaming process. A bottle cap 16 is located in the lower inner part of the mounting housing 11. The bottle cap 16 is connected to the foaming pump 12 and also to the liquid storage bottle 20. A silicone tube 17 is connected to the middle of the bottle cap 16 and is vertically inserted into the liquid storage bottle 20 to draw hand sanitizer from the bottle into the foaming pump. A PCB circuit board 18 is mounted on the upper end of the motor 13. This PCB circuit board 18 integrates a control chip, power management, and sensor control circuitry to implement automatic liquid dispensing and foam generation control logic. A foaming nozzle 19 is mounted on the upper front end of the mounting housing 11 for dispensing foamed hand sanitizer. The sinker 15 is connected to the foaming pump 12 via a conduit, and the foaming nozzle 19 is connected to the sinker 15 via a conduit, forming a complete foam supply path. During use, when the user's hand approaches the sensing area at the front of the device, the PCB circuit board 18 receives a trigger signal from the infrared or capacitive sensing module, controlling the motor 13 to start, thereby driving the foaming pump 12. Negative pressure draws the hand sanitizer through the silicone tube 17 from the storage bottle 20, into the sinker 15, where it mixes with air to form foam, which is then dispensed through the foaming nozzle 19. The entire process achieves contactless operation, is convenient and quick, and produces a uniform and fine liquid with dense foam, making it easy for users to use.

[0025] In practical implementation, a top cover 30 is embedded in the upper inner part of the mounting housing 11. A plurality of fixing through posts 111 are evenly provided on the inner side of the mounting housing 11. A plurality of fixing insert posts 31 are evenly protruding from the lower edge of the top cover 30. The plurality of fixing insert posts 31 correspond one-to-one with the plurality of fixing through posts 111. The plurality of fixing insert posts 31 are respectively inserted into the plurality of fixing through posts 111, thereby fixing the top cover 30 in the upper inner part of the mounting housing 11. In use, the installation of the top cover 30 not only protects the internal components such as the PCB circuit board 18 and the motor 13, but also prevents dust, moisture and other impurities from entering the equipment to a certain extent, thereby improving the durability and reliability of the whole machine.

[0026] In practical implementation, the inner bottom of the mounting housing 11 is symmetrically provided with mounting through-posts 112, which serve as a fixed support structure for the foaming pump. The foaming pump 12 is symmetrically provided with mounting ears 121 on both sides. The mounting ears 121 correspond to the mounting through-posts 112, and are connected and fixed to the mounting through-posts 112 by fasteners passing through the mounting ears 121, thereby fixing the foaming pump 12 to the inner bottom of the mounting housing 11, making installation convenient and stable.

[0027] In practical implementation, the lower inner part of the mounting housing 11 is provided with a bottle cap retaining ring 113. The inner side of the bottle cap retaining ring 113 is recessed with a connecting groove 114. The outer side of the bottle cap 16 is protruding with a connecting block 161 that is adapted to the connecting groove 114. The connecting block 161 is inserted into the connecting groove 114 and engaged, so that the bottle cap 16 is secured in the lower inner part of the mounting housing 11. The structure is simple and the assembly is convenient.

[0028] In practical implementation, the bottle cap retaining ring 113 has a connecting through hole 115 in the middle, the foaming pump 12 has a bottle cap connector 122 at the bottom, and the bottle cap 16 has a bottle cap receiving groove 162 in the middle. The bottle cap connector 122 is inserted into the bottle cap receiving groove 162, and a sealing rubber head 123 is sleeved on the outside of the bottle cap connector 122, thereby sealing the connection between the bottle cap 16 and the foaming pump 12. In use, the bottle cap connector 122 is inserted into and engaged in the bottle cap receiving groove 162 through the connecting through hole 115. Under the covering effect of the sealing rubber head 123, the entire interface connection is firm, reliable, and has good sealing performance, thus achieving a stable sealed connection between the liquid storage bottle 20 and the foaming pump 12. The hand sanitizer is drawn into the foaming pump through the silicone tube under the suction of the pump body, and after mixing with air, it forms foam and is sprayed out from the foaming nozzle.

[0029] In practice, the upper end of the liquid storage bottle 20 is provided with a threaded connector 21, and the inner side of the bottle cap 16 is provided with a threaded groove 163 that is adapted to the threaded connector 21. The threaded groove 163 and the threaded connector 21 are threadedly connected, so that the liquid storage bottle 20 can be detachably connected to the lower part of the body assembly 10.

[0030] In practical implementation, a silicone gasket 181 is provided between the PCB circuit board 18 and the motor 13 to form a buffer isolation layer between them, preventing the stability and lifespan of the circuit board from being affected by vibration or heat during the operation of the motor 13. Conductive plugs 131 are symmetrically provided on both upper sides of the motor 13, and conductive slots 182 are symmetrically provided on the surface of the PCB circuit board 18.
