Description

Technical Field

[0001] This utility model relates to the technical field of soap dispenser products, specifically to an automatic sensor soap dispenser. Background Technology

[0002] With the gradual improvement of people's living standards, soap dispensers are increasingly being used in bathrooms. In existing foam soap dispensers, there is usually a liquid storage bottle and a liquid pump. When the user puts his hand into the sensing area, the liquid pump sucks out the liquid in the bottle, achieving the effect of automatic liquid dispensing.

[0003] To ensure ease of use and disposability, most existing liquid storage bottles are disposable. However, disposable bottles are fully enclosed with only one opening connected to a pump. Lacking a pressure-balancing mechanism, the bottle deforms more significantly with each use, gradually flattening itself. This increases the suction power required by the pump and consequently, power consumption. To reduce power consumption, manufacturers are using softer, more flexible materials for the storage bottles. This allows the bottle to contract more easily as the internal pressure decreases, ensuring stable liquid extraction and reducing power consumption.

[0004] While this method can solve the power consumption problem of the liquid pump to some extent, the liquid storage bottle is made of soft material and is not easy to store. It is also prone to tilting, tipping over, or even breaking during transportation, which is inconvenient for transportation and still cannot meet the product's usage requirements, thus hindering the improvement of the product's competitiveness.

[0012] This utility model is further improved. The liquid extraction assembly includes a liquid extraction pump, a motor, a solenoid valve, a first liquid delivery pipe and a second liquid delivery pipe. The moving end of the motor is connected to the liquid extraction pump. The solenoid valve is provided with a first liquid delivery port and a second liquid delivery port. The liquid extraction pump is provided with a third liquid delivery port and a fourth liquid delivery port. The discharge connector is connected to the first liquid delivery port.

One end of the second liquid delivery pipe is connected to the fourth liquid delivery port, and the other end of the second liquid delivery pipe is connected to the discharge connector.

[0013] This utility model is further improved by placing the liquid storage bottle above the core assembly with the bottle opening facing downwards, placing the liquid outlet connector at the lower end of the core assembly, and providing a liquid outlet window on the soap dispenser body that matches the liquid outlet connector.

[0014] This utility model is further improved. The main body of the soap dispenser includes a front shell and a rear shell.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, and accompanying drawings are used to distinguish different objects, not to describe a particular order.

[0022] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figures 1-3 As shown, this utility model discloses an automatic sensor soap dispenser, comprising a soap dispenser body 1, a liquid storage bottle 2, a mechanism assembly, and a sensor control assembly within the soap dispenser body 1. The mechanism assembly is electrically connected to the sensor control assembly. The mechanism assembly includes a mechanism housing 3 and a liquid extraction component 4, a liquid outlet connector 5, and a liquid guide tube disposed within the mechanism housing 3. The liquid guide tube is provided with at least three branch connectors, namely a feed connector 6, a discharge connector, and an air inlet connector, and the three branch connectors are interconnected. The feed connector 6 is connected to the bottle opening of the liquid storage bottle 2, the discharge connector is connected to the liquid extraction component 4, and the liquid extraction component 4 is connected to the liquid outlet connector 5. The liquid extraction component 4 can work with the liquid guide tube to extract the liquid from the liquid storage bottle 2 to the liquid outlet connector 5. The air inlet connector is provided with a one-way valve 7, which can replenish air into the liquid storage bottle 2.

[0025] By using the liquid guide tube and the one-way valve 7, after each liquid extraction by the liquid extraction component 4, the internal air pressure of the liquid storage bottle 2 decreases. The one-way valve 7 can then open to replenish air into the liquid storage bottle 2, balancing the internal and external pressures. Once the pressure is balanced, the one-way valve 7 closes, ensuring that the internal air pressure of the liquid storage bottle 2 is at normal pressure each time the liquid extraction component 4 extracts liquid. This improves the stability of the extraction process, solves the problem of low internal air pressure in the liquid storage bottle 2 and difficulty in extraction, and enhances the user experience.

[0026] The number of branch connectors is three. The liquid guide tube includes a three-way connector 8 and three connecting pipes. The three connecting pipes are the feed pipe 9, the discharge pipe 10 and the air inlet pipe 11. The feed connector 6 is located at one end of the feed pipe 9, the discharge connector is located at one end of the discharge pipe 10 and the air inlet connector is located at one end of the air inlet pipe 11. The three-way connector 8 is provided with three connecting installation ports, which are respectively connected to the other end of the feed pipe 9, the discharge pipe 10 and the air inlet pipe 11.

[0027] The three-way connector 8 allows for the integration of gas pressure replenishment and infusion functions, effectively simplifying the structural design.

[0028] The tee connector 8 is Y-shaped. The feed pipe 9 and the air inlet pipe 11 are respectively connected to the two connecting ports on the top of the tee connector 8, and the discharge pipe 10 is connected to the connecting port on the bottom of the tee connector 8.

[0029] With this design, the feed pipe 9 and the discharge pipe 10 are connected vertically. Under the action of the liquid pumping component 4 and gravity, the liquid can be transferred from the feed pipe 9 to the discharge pipe 10 more effectively, which reduces the possibility of liquid flowing into the air inlet pipe 11.

[0030] The ventilation check valve 7 is a duckbill valve, with the duckbill end facing the air inlet pipe 11. By setting the duckbill valve, when the liquid storage bottle 2 is in a low-pressure state, the duckbill valve will automatically open under the action of internal and external pressure imbalance, so that the liquid storage bottle 2 is connected to the outside. Air enters the air inlet pipe 11 and finally enters the liquid storage bottle 2, so that the internal and external air pressure of the liquid storage bottle 2 is balanced. After the balance is achieved, the duckbill valve will automatically close to prevent liquid from flowing out of the product from the duckbill valve.

[0031] When the duckbill valve is not open, the outer wall of the duckbill valve is tightly fitted to the inner wall of the air inlet connector to prevent liquid from flowing out.

[0032] The mechanism assembly also includes a battery drawer 12. The mechanism housing 3 is provided with a drawer mounting opening 31 that mates with the battery drawer 12. The battery drawer 12 is disposed in the drawer mounting opening 31 and contains a power supply battery.

[0033] The battery drawer 12 allows for efficient battery installation and removal, improving the user experience and facilitating efficient battery swapping.

[0034] The drawer mounting opening 31 has a first snap-fit ​​groove 32 on its side, and the battery drawer 12 has a first snap-fit ​​plate 121 that mates with the first snap-fit ​​groove 32. The battery drawer 12 is snap-fit ​​connected to the mechanism housing 3.

[0035] The snap-fit ​​connection makes assembly more efficient.

[0036] The liquid extraction assembly 4 includes a liquid extraction pump 41, a motor 42, a solenoid valve 43, a first infusion pipe 44, and a second infusion pipe 45. The moving end of the motor 42 is connected to the liquid extraction pump 41. The solenoid valve 43 is provided with a first infusion port and a second infusion port. The liquid extraction pump 41 is provided with a third infusion port and a fourth infusion port. The discharge connector is connected to the first infusion port. One end of the first infusion pipe 44 is connected to the second infusion port, and the other end of the first infusion pipe 44 is connected to the third infusion port. One end of the second infusion pipe 45 is connected to the fourth infusion port, and the other end of the second infusion pipe 45 is connected to the discharge connector 5.

[0037] When a signal is received from the user using the product, the solenoid valve 43 opens the liquid extraction signal, connecting the first and second infusion ports, and the liquid extraction pump 41 starts extracting liquid.

[0038] The liquid storage bottle 2 is located above the mechanism assembly, with the bottle opening facing downwards. The liquid outlet connector 5 is located at the lower end of the mechanism assembly. The soap dispenser body 1 is provided with a liquid outlet window 101 that cooperates with the liquid outlet connector 5.

[0039] This positioning makes it easier for the liquid in the storage bottle 2 to be drawn out by the pump 41. Furthermore, due to gravity, the liquid in the storage bottle 2 is more concentrated at one end of the bottle opening, preventing the pump 41 from being unable to completely draw out the liquid in the storage bottle 2 and thus avoiding waste of consumables.

[0040] The soap dispenser body 1 includes a front shell 102 and a rear shell 103. The rear shell 103 has hinge grooves 1031 on both sides of its lower end. The inner wall of the front shell 102 has hinge posts that cooperate with the hinge grooves 1031. The hinge posts are located in the hinge grooves 1031, allowing the front shell 102 to swing around the hinge grooves 1031. The rear shell 103 has a rear locking part at its upper end, and the front shell 102 has a front locking part that cooperates with the rear locking part.

[0041] This design makes product maintenance much easier.

[0042] The sensing control component is equipped with a distance sensor 13, which is located on the side of the liquid outlet connector 5. By setting the distance sensor 13, the user's usage needs can be identified through distance sensing. When the user moves to the sensing area, the signal is transmitted to the sensing control component to control the liquid extraction component 4 to perform the liquid extraction process.

[0043] This mechanism effectively solves the problems of unbalanced air pressure inside and outside the storage bottle 2 of existing automatic soap dispensers, which leads to unstable liquid extraction and high power consumption. By using this product structure, the cooperation between the liquid guide tube and the one-way valve 7 allows the one-way valve 7 to open and replenish air into the storage bottle 2 after each liquid extraction by the extraction component 4. This balances the pressure inside and outside the storage bottle 2. After the pressure is balanced, the one-way valve 7 closes, ensuring that the air pressure inside the storage bottle 2 is at normal pressure each time the extraction component 4 extracts liquid. This improves the stability of liquid extraction, solves the problems of low air pressure inside the storage bottle 2, difficulty in liquid extraction, and high power consumption, and enhances the user experience and product competitiveness.

[0044] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
