Description

Technical Field

[0001] This utility model relates to the technical field of soap replenishment devices, and in particular to a soap replenishment device that prevents the generation of bubbles. Background Technology

[0002] A soap refill device is used to replenish soap dispensers. Typically, soap dispensers are countertop mounted, with the main unit and liquid tank located underneath. Conventional refilling methods require disassembling the liquid tank, which is cumbersome. Traditional soap refill devices use a refill pipe, with one end connected to the liquid tank and the other end extending to the countertop, making it easy to refill from the countertop.

[0003] Existing soap replenishment devices, such as Chinese Utility Model Patent CN201720792774.1, describe a soap supply device for a soap dispenser. This device includes a soap container and a replenishment module. The soap container holds the soap, and the replenishment module is connected to the soap container via a soap pipe. Soap flows into the soap container through the replenishment module and soap pipe, replenishing the container. The device also includes a level sensor, a main control board, and a level indicator module. The level sensor detects the soap level in the container, and the level indicator module indicates the soap level. The soap container has a vent at the top. In this patent, the soap pipe connects to the top of the soap container, allowing soap to enter from above. Air inside the container is expelled through the vent, and the level sensor detects changes in the liquid level, displaying the level on the level indicator module. This allows the user to stop replenishing when the container is full. First, during the replenishment process, the soap solution enters the soap solution container from top to bottom, which impacts the soap solution inside the container, causing air to enter and mix with it, generating a large number of bubbles. A large number of bubbles will affect the sensing accuracy of the liquid level sensor, resulting in the liquid level not actually being filled when the sensor indicates that it is full. Second, even if the sensing sensitivity of the liquid level sensor is adjusted to eliminate the interference of bubbles, the bubbles will still be discharged from the vent. Since the bubbles still contain some soap solution, this will cause a small amount of soap solution to overflow and cause contamination. Therefore, it is necessary to improve this system.

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a soap replenishment device that prevents the generation of bubbles during replenishment, thus avoiding the overflow of soap during replenishment. The device has a simple structure and low cost.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a soap replenishment device to prevent the generation of bubbles, comprising a replenishment connector, a replenishment pipe, and a storage tank. The replenishment pipe is connected between the replenishment connector and the storage tank. An exhaust port is provided at the upper part of the storage tank, and an inlet is provided at the lower part of the storage tank. A float valve is also provided inside the storage tank, and the float valve is sealed to the exhaust port. The vertical height of the replenishment connector is higher than that of the storage tank. The upper end of the replenishment pipe is connected to the replenishment connector, and the lower end of the replenishment pipe is connected to the inlet of the storage tank.

[0006] In a further technical solution, the liquid inlet is located on the lower end face of the liquid storage tank, and a liquid inlet pipe extends downward from the outer edge of the liquid inlet. The lower end of the liquid replenishment pipe is connected to the liquid inlet pipe.

[0007] In a further technical solution, a quick-connect elbow is used to connect the inlet pipe and the replenishment pipe.

[0008] In a further technical solution, the storage tank includes a tank body and a tank cover. The tank cover is fixedly installed at the opening of the tank body. A supply pipe for connecting a soap dispenser is provided in the center of the tank cover. The lower end of the supply pipe extends into the lower part of the tank body. The tank cover is also provided with a downwardly protruding vent column. The vent column is located next to the supply pipe. The vent is opened on the vent column. The upper end of the vent is connected to the atmosphere, and the lower end is connected to the inner cavity of the tank body. A float valve is hinged to the tank cover, and the float valve and the vent column abut against each other.

[0009] In a further technical solution, the liquid inlet is located at the center of the lower end face of the tank, the lower end of the liquid supply pipe extends into the liquid inlet pipe, and a buffer gap is formed between the outer wall of the liquid supply pipe and the inner wall of the liquid inlet pipe.

[0010] In a further technical solution, a liquid supply check valve is provided at the lower end of the liquid supply pipe. The output end of the liquid supply check valve extends into the liquid inlet pipe, and a buffer gap is formed between the liquid supply check valve and the inner wall of the liquid inlet pipe.

[0011] In a further technical solution, a liquid replenishment check valve is installed inside the liquid replenishment connector or in the liquid replenishment pipe, with the output end of the liquid replenishment check valve facing the liquid inlet.

[0014] The advantages of this invention compared to existing technologies are as follows: By placing the inlet at the bottom of the storage tank, the soap solution enters from bottom to top during replenishment. The existing soap solution in the tank acts as a buffer, reducing the impact on the liquid surface and preventing bubble formation. The vent is located at the top of the storage tank, allowing air to escape smoothly during replenishment and preventing pressure buildup. After the tank is full, the liquid level rises to its highest value, and the float valve automatically seals the vent to balance the pressure difference between the inside and outside of the tank, thus automatically stopping replenishment and preventing soap solution from overflowing from the vent after the tank is full. The structure is simple and low-cost. The float valve not only automatically stops replenishment but also physically seals the vent, resulting in a compact structure with high reliability and stability. The one-way valve prevents air from entering the storage tank from the replenishment pipe, further reducing the probability of bubble formation. Attached Figure Description

[0018] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0019] A soap dispenser that prevents the formation of bubbles, such as Figures 1 to 3As shown, it includes a replenishment connector 1, a replenishment pipe 2, and a storage tank 3. The replenishment pipe 2 is connected between the replenishment connector 1 and the storage tank 3. The upper part of the storage tank 3 is provided with an exhaust port 322, and the lower part of the storage tank 3 is provided with an inlet 311. The storage tank 3 is also provided with a float valve 4, which is sealed to the exhaust port 322. The vertical height of the replenishment connector 1 is higher than that of the storage tank 3. The upper end of the replenishment pipe 2 is connected to the replenishment connector 1, and the lower end of the replenishment pipe 2 is connected to the inlet 311 of the storage tank 3. Traditional soap replenishment devices introduce soap from the top of the storage tank 3. This process impacts the liquid surface, generating numerous bubbles that cause soap to overflow from the vent 322. Furthermore, traditional devices require an electronic level gauge to determine replenishment completion, resulting in a complex and costly design that necessitates constant monitoring. In contrast, this invention places the inlet 311 at the bottom of the storage tank 3. During replenishment, soap enters from the bottom up, with the existing soap in the tank acting as a buffer, reducing the impact on the liquid surface. To prevent air bubbles from forming, the vent 322 is located at the top of the storage tank 3, allowing air to escape smoothly during replenishment and preventing pressure buildup. After the storage tank 3 is filled, the liquid level rises to its highest value, and the float valve 4 automatically seals the vent 322 to balance the pressure difference inside and outside the storage tank 3, thus automatically stopping replenishment and preventing soap solution from overflowing from the vent 322 after the tank is full. The structure is simple and low-cost. The float valve 4 not only automatically stops replenishment but also physically seals the vent 322, resulting in a compact structure and high reliability and stability.

[0020] Specifically, the inlet 311 is located on the lower end face of the storage tank 3, and an inlet pipe 312 extends downward from the outer edge of the inlet 311. The lower end of the replenishment pipe 2 is connected to the inlet pipe 312. The inlet 311 is located at the lowest point of the storage tank 3, allowing the soap solution to enter smoothly from the bottom, further reducing bubble generation and avoiding disturbance to the liquid surface. The extended inlet pipe 312 improves the sealing of the connection with the replenishment pipe 2, preventing leakage, and also facilitates installation.

[0021] Specifically, a quick-connect elbow 5 connects the inlet pipe 312 and the replenishment pipe 2. The quick-connect elbow 5 allows for quick connection and disconnection, simplifying installation and maintenance processes and improving ease of use. The quick-connect elbow 5 makes the inlet pipe 312 perpendicular to the replenishment pipe 2, changing the direction of the replenishment pipe 2, reducing pipe bending resistance, ensuring smooth soap flow, reducing vertical installation space requirements, avoiding blockages caused by bending of the replenishment pipe 2, and improving reliability and stability.

[0022] Specifically, the storage tank 3 includes a tank body 31 and a tank cover 32. The tank cover 32 is fixedly installed at the opening of the tank body 31. A supply pipe 323 for connecting to the soap dispenser is provided in the center of the tank cover 32. The lower end of the supply pipe 323 extends into the lower part of the tank body 31. The tank cover 32 also has a downwardly protruding vent column 321, which is located beside the supply pipe 323. A vent port 322 is opened in the vent column 321. The upper end of the vent port 322 communicates with the atmosphere, and the lower end communicates with the inner cavity of the tank body 31. A float valve 4 is hinged to the tank cover 32, and the float valve 4 abuts against the vent column 321. The tank cover 32 integrates the supply pipe 323 and the vent column 321, resulting in a compact structure, reducing the number of parts, and lowering the assembly complexity. The supply pipe 323 extends into the lower part of the tank body 31 to ensure that the soap is drawn from the bottom, avoiding the introduction of air during drawing and reducing air bubbles. The exhaust column 321 provides a dedicated exhaust channel. The float valve 4 is hinged to the exhaust column 321 to achieve a reliable seal and sensitive response, automatically closing the exhaust port 322 when the liquid is full. The float valve 4 is hinged to the exhaust column 321, resulting in a more compact structure, higher integration, shorter closing stroke, and improved reaction speed.

[0023] Specifically, the inlet 311 is located at the center of the lower end face of the tank 31. The lower end of the supply pipe 323 extends into the inlet pipe 312, forming a buffer gap between the outer wall of the supply pipe 323 and the inner wall of the inlet pipe 312. The central location of the inlet 311 ensures that the soap solution enters the storage tank 3 evenly, avoiding localized turbulence. The buffer gap further reduces the probability of bubble formation by diverting and buffering the flow. The supply pipe 323 extends into the inlet pipe 312, thus limiting its movement. Since the lower end of the supply pipe 323 is a free end, it is limited by extending into the inlet pipe 312 to prevent large-angle bending or displacement.

[0024] Specifically, a liquid supply check valve 324 is provided at the lower end of the liquid supply pipe 323. The output end of the liquid supply check valve 324 extends into the liquid inlet pipe 312, and a buffer gap is formed between the liquid supply check valve 324 and the inner wall of the liquid inlet pipe 312. The liquid supply check valve 324 prevents the soap solution from flowing backward and avoids air from entering the storage tank 3 from the soap dispenser through the liquid supply pipe 323. At the same time, when replenishing the soap solution, the soap solution directly impacts the liquid supply check valve 324, thereby diverting the soap solution to the surrounding areas to reduce the vertical impact force of the soap solution.

[0025] Specifically, a one-way valve 13 is installed inside the replenishment connector 1 or in the replenishment pipe 2, with the output end of the one-way valve 13 facing the inlet 311. The one-way valve 13 prevents air from entering the storage tank 3 from the replenishment pipe 2 and also prevents soap solution from flowing back up and overflowing from the replenishment connector 1, further reducing the probability of bubble formation. During the replenishment process, the soap solution is ensured to flow in one direction, improving the cleanliness and efficiency of the replenishment.

[0026] Specifically, the replenishment connector 1 has an upward-facing connection slot 11, and a liquid outlet 12 is located at the lower part of the connector 1. A replenishment check valve 13 is embedded in the lower part of the connection slot 11 and connected to the liquid outlet 12. The upper end of the replenishment tube 2 is connected to the liquid outlet 12. The connection slot 11 facilitates quick connection to an external replenishment source, improving the user experience. The replenishment check valve 13 is integrated into the replenishment connector 1, has a compact structure, reduces the risk of leakage, and is located at a relatively high point. It can quickly and automatically close after replenishment to prevent air from entering the replenishment tube 2. For the next replenishment, it directly connects to an external replenishment source, thereby further preventing air from entering.

[0027] Specifically, the lower part of the refill connector 1 is connected to an installation sleeve 6, and the lower part of the installation sleeve 6 is provided with a liquid outlet pipe 61. The liquid outlet pipe 61 is plugged into a quick-connect connector 7, and the upper end of the refill pipe 2 is connected to the quick-connect connector 7. A nut is screwed into the lower part of the installation sleeve 6, which facilitates the installation of the refill connector 1 on the countertop and increases the length of the refill connector 1 to accommodate washbasins of different thicknesses. The quick-connect connector 7 facilitates quick installation and connection. The quick-connect connector 7 can also be a T-joint or multi-way connector to connect multiple soap dispensers for refilling simultaneously.

[0028] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
