Description

Technical Field

[0001] This utility model relates to the technical field of soap replenishment devices, and in particular to a non-powered soap replenishment device. Background Technology

[0002] A soap dispenser, also known as a soap dispenser or soap dispenser machine, is a sanitary device that automatically or manually dispenses a measured amount of soap. It is mainly used in hotels, hospitals, public places, and homes to reduce contact contamination and improve ease of use. For aesthetic reasons, soap dispensers are often countertop-mounted, meaning both the main unit and the liquid tank are located under the sink. When the soap in the tank runs out, it needs to be refilled. Traditionally, this involves disassembling the tank for refilling or replacing it with a new one. However, in public places, a single sink often has multiple basins, requiring a soap dispenser for each basin. Furthermore, the high soap consumption in public places necessitates frequent refilling, which is cumbersome, inefficient, and impacts usability.

[0003] In the prior art, such as Chinese utility model patent CN202020348866.2, a hospital hand sanitizer supply device includes a main controller, a storage tank, a buffer tank, infusion pipes, a water pump, and multiple soap dispensers located at the handwashing station. The soap dispensers are intelligent sensor-operated soap dispensers that automatically sense and dispense a fixed amount of hand sanitizer. The storage tank contains hand sanitizer, and the buffer tank is located to the side of the storage tank. A water pump is installed between the storage tank and the buffer tank. The buffer tank has the same capacity as the soap dispensers. The outlet of the buffer tank is connected to the inlets of the multiple soap dispensers via multiple infusion pipes. An electromagnetic switch is installed at the connection between the infusion pipe and the soap dispenser, and a second water pump is installed at the connection between the infusion pipe and the outlet of the buffer tank. A wireless level gauge is installed inside each soap dispenser and is wirelessly connected to the main controller. The main controller is connected to the water pump and the second water pump, and is also wirelessly connected to the multiple electromagnetic switches. This patent uses a wireless level gauge to measure the liquid level signal, then transmits the empty bottle signal to the controller. The controller uses a water pump to deliver the hand sanitizer in the storage tank to the buffer tank, and then uses a second water pump and an electromagnetic switch to deliver the hand sanitizer to the soap dispenser in the empty bottle, thus replenishing the hand sanitizer. The structure is complex, with many electrical components, a high failure rate, and high cost, so it is necessary to improve it. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a non-powered soap dispenser replenishment device that can simultaneously replenish soap dispensers, thereby improving replenishment efficiency. It features a simple structure and low cost.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a non-powered soap replenishment device, comprising a replenishment tank, a quick-connect replenishment connector, a distributor, multiple dispensing pipes, and multiple storage tanks.

[0019] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0020] A non-powered soap dispenser, such as Figures 1 to 5As shown, the device includes a replenishment tank 1, a quick-connect replenishment connector, a distributor 3, multiple distribution pipes 4, and multiple storage tanks 5. The replenishment tank 1 is connected to the quick-connect replenishment connector, which is connected to the distributor 3. Each storage tank 5 is equipped with an inlet and an outlet 531. One end of each distribution pipe 4 is connected to the inlet of each storage tank 5, and the other end is connected to the distributor 3. Each storage tank 5 is equipped with a float valve for sealing the inlet or outlet 531. When replenishing soap solution, the height of the replenishment tank 1 is higher than the height of each storage tank 5. Traditional soap dispenser replenishment devices require a pump and level gauge for automatic replenishment, resulting in complex structures, high costs, pre-installation during the renovation phase, and a high failure rate. Replenishing each soap dispenser individually is cumbersome and inefficient. This invention, however, utilizes gravity to simultaneously replenish multiple storage tanks 5 using a replenishment tank 1, improving replenishment efficiency. Once a storage tank 5 is full, a float valve automatically stops the replenishment without affecting other tanks 5 that are not yet full, continuing this process until all tanks 5 are full, thus preventing soap spillage and ensuring even and consistent replenishment. Gravity-based replenishment with automatic float valve shut-off results in a simple structure and low cost.

[0021] Specifically, the float valve includes a float 61, a rotating rod 62, and a sealing plug 63. The first end of the rotating rod 62 is rotatably mounted on the upper part of the inner cavity of the storage tank 5. The float 61 is located at the second end of the rotating rod 62. The sealing plug 63 is fixedly mounted on the upper part of the rotating rod 62, and the sealing plug 63 abuts against the inlet or vent 531. During the replenishment process, the soap solution enters the storage tank 5 from the inlet by gravity, while the air inside the storage tank 5 is discharged from the vent 531, thereby balancing the pressure difference and allowing the soap solution to enter the storage tank 5 quickly. When the float 61 rises to a high position with the liquid level, the float 61 drives the rotating rod 62 to rotate, causing the sealing plug 63 to move upward to seal the inlet or vent 531, thereby stopping the replenishment. When sealing the liquid inlet, the sealing plug 63 directly seals the liquid inlet, thereby preventing soap solution from entering. When sealing the vent 531, the sealing plug 63 blocks the vent 531, preventing air from escaping from the storage tank 5. This creates a pressure difference between the storage tank 5 and the atmosphere, preventing soap solution from entering the storage tank 5.

[0022] Specifically, the storage tank 5 is provided with a soap supply pipe 54 for connecting the soap dispenser. The float 61 has a through hole 611 in the middle. The float 61 is slidably installed on the soap supply pipe 54 through the through hole 611. The float 61 and the second end of the rotating rod 62 are engaged in abutment. Because the volume of the storage tank 5 is small, usually not exceeding 1L, and the diameter of the storage tank 5 is also relatively small, fixing the float 61 to the end of the rotating rod 62 would occupy a lot of lateral space, resulting in the only option to reduce the length of the rotating rod 62. After the length of the rotating rod 62 is reduced, the lever arm is also reduced. Furthermore, the internal space of the storage tank 5 is limited, and the buoyancy of the soap solution in the storage tank 5 on the float 61 is low, which can easily lead to a decrease in the sealing performance of the float valve. Especially when sealing the inlet, the float valve is subjected to positive pressure, which can easily lead to poor sealing and the phenomenon of soap solution overflowing from the vent 531. However, by sliding the float 61 onto the soap supply pipe 54, the soap supply pipe 54 can not only limit the position of the float 61, but also reduce the lateral space occupied by the float valve, increase the length of the rotating rod 62 to increase the lever arm, and also increase the volume of the float 61 to increase the buoyancy, thereby enhancing the sealing performance of the float valve, avoiding leakage, and improving reliability and stability.

[0023] Specifically, the storage tank 5 includes a tank body 51 and a tank cover 52. The tank cover 52 is fixedly installed at the opening of the tank body 51. The tank cover 52 is provided with a connecting post 53 extending into the tank body 51. An exhaust port 531 or a liquid inlet is opened on the connecting post 53. A soap supply tube 54 passes through the center of the tank cover 52. The connecting post 53 is located beside the soap supply tube 54. A sealing plug 63 abuts against the lower end of the connecting post 53. The connecting post 53 extends into the tank body 51 to facilitate cooperation with the float valve. The lower end face of the connecting post 53 is flat, which facilitates a close fit with the sealing plug 63, reduces gaps, and further improves the sealing performance.

[0024] Specifically, the float valve also includes a connecting sleeve 64, which is sleeved on the lower part of the connecting column 53. The connecting sleeve 64 has a through hole 641 at the position corresponding to the vent port 531 or the liquid inlet. The first end of the rotating rod 62 is hinged to the side of the connecting sleeve 64 away from the soap supply tube 54. The through hole 641 is located between the rotating shaft of the soap supply tube 54 and the rotating rod 62. The middle part of the rotating rod 62 has a relief opening 621 that passes through the rotating rod 62. The soap supply tube 54 passes through the relief opening 621, and the inner wall of the relief opening 621 is in a limiting fit with the soap supply tube 54. The rotating rod 62 is mounted on the connecting column 53 via the connecting sleeve 64. The installation structure is simple; during production, only individual components need to be manufactured and then assembled one by one, eliminating the need for complex connection and fixing structures on the tank body 51 or tank cover 52, thus simplifying the production process and reducing production costs. During assembly, the connecting sleeve 64 is fitted onto the lower end of the connecting column 53, with the through hole 641 located below the vent port 531 or liquid inlet. The rotating rod 62 is then hinged to the connecting sleeve 64. The connecting sleeve 64 has... The sleeve has a protruding post with an installation ramp, and the rotating rod 62 has two rotating holes. The rotating holes are connected to the protruding post through the installation ramp to complete the assembly. The protruding post is located on the side of the connecting sleeve 64 near the inner wall of the tank 51. The rotating rod 62 passes through the soap supply pipe 54 through the clearance port 621, thereby further increasing the length of the rotating rod 62 and improving the lever arm. The clearance port 621 and the soap supply pipe 54 also serve as a limit to prevent the rotating rod 62 from rotating excessively downward when the liquid level drops, further simplifying the structure and reducing costs.

[0025] Specifically, the second end of the rotating rod 62 is provided with a downwardly protruding abutment 622, which abuts against the float 61. The float 61 abuts against the rotating rod 62 through the abutment 622, ensuring that the force of the float 61 is located at the second end of the rotating rod 62, thereby improving reliability and stability.

[0026] Specifically, the quick-connect refill device includes a refill socket 21 and a refill plug 22. The refill socket 21 connects to the distributor 3, and the refill plug 22 connects to the refill tank 1. The refill socket 21 and the refill plug 22 are plugged into each other. When the soap solution is sufficient, there is no need to connect the refill tank 1 for refilling. When refilling, the operator only needs to connect the refill socket 21 and the refill plug 22, without the need for auxiliary tools such as funnels, making the operation more convenient.

[0027] Specifically, a refill plug 22 is connected to the refill container 1 via a refill hose 11. Since the refill container 1 is relatively large and heavy when filled with soap solution, moving the container to insert the refill plug 22 into the refill socket 21 is more difficult. Therefore, by providing the refill hose 11, the refill socket 21 and the refill plug 22 can be connected without moving the container 1, improving operational convenience.

[0028] Specifically, the refill hose 11 is connected to the lower part of the refill tank 1, and an air inlet valve 12 is provided on the upper part of the refill tank 1. Before connecting the refill socket 21 and the refill plug 22, the air inlet valve 12 is closed to balance the internal pressure of the refill tank 1 and prevent soap from flowing out. After the refill socket 21 and the refill plug 22 are connected, the air inlet valve 12 is opened to allow outside air to enter the interior of the refill tank 1, so that soap can flow out for refilling and to prevent soap from splashing.

[0029] Specifically, the replenishment container 1 is made of a semi-transparent material. The semi-transparent material allows the height of the soap solution inside the replenishment container 1 to be observed from the outside, so as to judge the capacity of the soap solution inside the replenishment container 1. When replenishing, the change in the liquid level inside the replenishment container 1 is observed to determine whether the replenishment is complete.

[0030] When using this utility model: First, place the IV refill container 1 on the sink, insert the IV refill plug 22 into the IV refill socket 21, and then open the air inlet valve 12. Figure 4 As shown, air enters the replenishment tank 1 through the air inlet valve 12, and the soap solution in the replenishment tank 1 flows into each liquid distribution pipe 4 through the distributor 3. At this time, the air in the storage tank 5 is discharged from the exhaust port 531, and the soap solution in each liquid distribution pipe 4 enters each storage tank 5 respectively. like Figure 5 As shown, when a portion of the storage tank 5 is filled with soap solution, the float 61 rises to the surface of the liquid and touches the protrusion 622, causing the rotating rod 62 to rotate upwards. This causes the sealing plug 63 to move upwards and seal the vent 531. At this time, external air cannot enter the storage tank 5, and the pressure inside and outside the storage tank 5 is balanced, preventing soap solution from entering the storage tank 5. Meanwhile, the partially filled storage tank 5 continues to receive liquid until the float valve seals the vent 531. By observing the change in the liquid level in the replenishment tank 1, once the liquid level in the replenishment tank 1 remains constant, the replenishment is deemed complete. The replenishment plug 22 is then unplugged to complete the replenishment.

[0031] 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.
