Description

Technical Field

[0001] This utility model relates to the technical field of soap refill devices, and in particular to a soap refill device with a full liquid reminder. Background Technology

[0002] A soap dispenser is a sanitary device that automatically dispenses a measured amount of soap. It is primarily 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, with both the main unit and the liquid tank located below the countertop. Refilling the tank requires opening the cabinet door, making the process cumbersome. In existing technology, such as Chinese utility model patent CN201220633763.6, a soap dispenser for high-speed trains includes a soap dispensing port, a soap dispenser box, and an infusion tube. The soap dispensing port is connected to the soap dispenser box via the infusion tube. The soap dispensing port is fixed to a table surface and includes a soap dispensing cap and a soap dispensing base. The soap dispensing base is fixed to the table surface, and the infusion tube is fixedly connected to the bottom of the soap dispensing base. A spring-loaded retaining ball is provided inside the soap dispensing cap, and the spring-loaded retaining ball includes two retaining balls connected by a spring. The soap dispensing cap is fixed to the soap dispensing base via the spring-loaded retaining ball. This patent fixes the soap dispensing port to the table surface and connects it to a soap dispenser box located below the table, thus allowing soap to be replenished on the table surface through the soap dispensing port. However, during the replenishment process, one can only observe whether soap is overflowing from the soap filling port to determine whether the replenishment is complete. Therefore, soap is prone to overflowing from the soap filling port. Furthermore, during the replenishment process, the outlet of the replenishment container used for replenishment is often directly inserted into the soap filling port, causing the soap filling port to be blocked and making it impossible to observe. One can only judge by observing the liquid level change in the replenishment container, and there is no way to provide proactive reminders.

[0003] Another Chinese invention patent, CN201710755739.7, discloses an automatic soap replenishment system. This system comprises multiple soap dispensing bodies for discharging soap, multiple soap dispensing components connected to each soap dispensing body, a soap filling tank connected to each soap dispensing component via a replenishment pipe with an exhaust valve at one end, a tabletop mounting assembly for fixing the soap filling tank and having a soap replenishment light display area, and a control unit for forming the soap replenishment light display area. A liquid level difference exists between the soap filling tank and the soap dispensing components, allowing soap to automatically fill from the soap filling tank into the soap dispensing components using this difference. The soap replenishment light display area confirms whether replenishment is needed. This patent incorporates a liquid level detection unit within the soap filling tank to sense the liquid level and indicate whether replenishment is complete. However, this structure is complex, costly, requires a power supply, and suffers from signal transmission delay, thus necessitating improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a soap refilling device with a full-liquid indicator. This device has a simple structure, low cost, and provides audible alerts during the refilling process, making it easy to stop the refilling operation at any time and reducing the risk of soap spillage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a soap refilling device with a full liquid reminder, comprising a storage tank, a refill pipe, and a refill base. The refill base is connected to the refill pipe, and the refill pipe is connected to the storage tank. The storage tank is provided with an inlet and an exhaust port. The inlet is connected to the refill pipe, and the exhaust port is provided with a blowing component for generating an alert sound by venting. A float valve is provided inside the storage tank, and the float valve is sealed to the exhaust port or the inlet.

[0006] 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. The tank cover is provided with an exhaust column that extends into the tank body. An exhaust port is opened on the exhaust column. The upper end of the exhaust port is connected to the atmosphere, and the lower end is connected to the inner cavity of the tank body. The float valve is sealed to the lower end of the exhaust port.

[0007] In a further technical solution, the blowing component is provided with an airflow hole, which is located below the exhaust hole and forms a stepped hole with the exhaust hole. The diameter of the airflow hole is smaller than the diameter of the exhaust hole, and the float valve is sealed to the airflow hole.

[0008] In a further technical solution, the diameter of the airflow hole is 1~3mm, and the ratio between the exhaust hole and the airflow hole is 3.3~3.9.

[0009] In a further technical solution, the ratio between the length of the exhaust hole and the diameter of the exhaust hole is 4.5 to 5.5.

[0010] In a further technical solution, the airflow hole is a conical hole, and the diameter of the upper end of the airflow hole is larger than the diameter of the lower end.

[0011] In a further technical solution, the blowing assembly includes a blowing sleeve, which is fitted onto the lower end of the exhaust column. An airflow hole is opened in and passes through the blowing sleeve, and a float valve abuts against the blowing sleeve.

[0012] In a further technical solution, the lower part of the blowing sleeve is provided with a downwardly protruding sound-generating protrusion, the airflow hole passes through the sound-generating protrusion, and the float valve abuts against the sound-generating protrusion.

[0013] In a further technical solution, the blowing component includes a reed, which is disposed within the exhaust port.

[0014] In a further technical solution, the blowing component includes a whistle, which is fixedly installed on the liquid storage tank, and the air inlet of the whistle is connected to the upper end of the exhaust port.

[0015] The advantages of this invention compared to existing technologies are as follows: By installing a blowing component at the vent, during replenishment, the replenishment base is placed on the platform to connect the replenishment tank. Soap solution enters the storage tank through the replenishment pipe. Air in the storage tank is compressed and discharged from the vent, generating a whistle through the blowing component. When the tank is full, the float valve seals the inlet or vent to prevent soap solution from entering, thus stopping the blowing of air onto the blowing component and stopping the whistle. The whistle indicates that replenishment is in progress, and the whistle disappears when the tank is full. The structure is simple and low-cost. It uses whistle sound for identification, eliminating the need for visual observation and power supply, allowing for timely cessation of replenishment operations and reducing the risk of soap solution spillage. It also serves as a reminder when the operator is away, facilitating timely cessation of replenishment and reducing waiting time. Attached Figure Description

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

[0020] Example 1 A soap refill device with a full-liquid indicator, such as Figures 1 to 3As shown, it includes a liquid storage tank 1, a liquid replenishment pipe 2, and a liquid replenishment base 3. The liquid replenishment base 3 is connected to the liquid replenishment pipe 2, and the liquid replenishment pipe 2 is connected to the liquid storage tank 1. The liquid storage tank 1 is provided with a liquid inlet and a vent 14. The liquid inlet is connected to the liquid replenishment pipe 2, and the vent 14 is provided with a blowing component for generating a prompting sound through venting. A float valve 5 is provided inside the liquid storage tank 1, and the float valve 5 is sealed and cooperates with the vent 14 or the liquid inlet. Traditional soap replenishment devices lack a full-level indicator, requiring visual inspection and prone to leakage. Some require electronic level gauges to detect the liquid level, resulting in complex structures, high costs, and high failure rates. This invention, however, incorporates a whistling component at the vent 14. During replenishment, the replenishment base 3 is placed on a platform to connect the replenishment tank. Soap solution enters the storage tank 1 through the replenishment pipe 2. Air in the storage tank 1 is pressurized and expelled through the vent 14, generating a whistle through the whistling component. When the tank is full, the float valve 5 seals the inlet or vent 14 to prevent further soap solution from entering, thus stopping the blowing of air onto the whistling component and stopping the whistle. The whistle indicates replenishment is in progress, and its absence indicates fullness. This design is simple, low-cost, and uses whistle sound for identification, eliminating the need for visual inspection and power supply. It allows for timely cessation of replenishment, reducing the risk of soap spillage. Furthermore, it serves as a reminder when the operator is away, facilitating timely cessation of replenishment and minimizing waiting time.

[0021] Specifically, the storage tank 1 includes a tank body 11 and a tank cover 12. The tank cover 12 is fixedly installed at the opening of the tank body 11. The tank cover 12 is provided with an exhaust column 13, which extends into the tank body 11. An exhaust port 14 is opened in the exhaust column 13. The upper end of the exhaust port 14 communicates with the atmosphere, and the lower end communicates with the inner cavity of the tank body 11. The float valve 5 is sealed to the lower end of the exhaust port 14. To prevent soap solution from overflowing from the exhaust port 14 during replenishment, an exhaust column 13 is provided in the tank cover 12 to open the exhaust port 14, so that the exhaust port 14 is located at the upper part of the storage tank 1 to prevent soap solution from overflowing; and the downward protruding exhaust column 13 facilitates the sealing of the float valve 5.

[0022] Specifically, the sound-blowing component is equipped with an airflow hole 42, which is located below the exhaust hole 14 and forms a stepped hole with the exhaust hole 14. The diameter of the airflow hole 42 is smaller than the diameter of the exhaust hole 14, and the float valve 5 is sealed to the airflow hole 42. When airflow enters the exhaust hole 14 from inside the liquid storage tank 1 through the airflow hole 42, the airflow velocity increases sharply as it passes through the narrow airflow hole 42 because the diameter of the airflow hole 42 is much smaller than the diameter of the exhaust hole 14. Subsequently, it suddenly expands after entering the larger diameter exhaust hole 14, generating eddies and pressure fluctuations. These eddies and pressure changes cause air vibrations, thereby producing high-frequency sounds, similar to whistling. The stepped hole structure formed by the airflow hole 42 and the exhaust hole 14 enhances the instability of the airflow, strengthens the sound production effect, and has a simple structure and low cost.

[0023] Specifically, the diameter of the airflow hole 42 is 1~3mm, and the ratio between the exhaust hole 14 and the airflow hole 42 is 3.3~3.9. Preferably, the diameter of the airflow hole 42 is 1.8~2.2mm, and the diameter of the exhaust hole 14 is 7.0~7.4mm.

[0024] Specifically, the ratio between the length and diameter of the vent hole 14 is 4.5 to 5.5. Preferably, the length of the vent hole 14 is 35 to 37 mm. Increasing the length of the vent hole 14 by the vent column 13 is similar to the sound hole of a flute, thereby producing a specific pitch, loud and clear note, transforming the exhaust sound into a clear, loud, stable, and well-spread whistle, greatly improving the effectiveness of the full liquid reminder and the user experience.

[0025] Specifically, the blowing assembly includes a blowing sleeve 41, which is fitted onto the lower end of the exhaust column 13. An airflow hole 42 is formed in and passes through the blowing sleeve 41. A float valve 5 abuts against the blowing sleeve 41. The airflow hole 42 is formed on the blowing sleeve 41, eliminating the need for machining stepped holes during production. The blowing sleeve 41 is simply formed and then directly fitted onto the exhaust column 13, resulting in a simple structure and ease of production. The float valve 5 directly seals the airflow hole 42. As the liquid level approaches full, the distance between the float valve 5 and the airflow hole 42 continuously decreases, increasing the airflow velocity entering the airflow hole 42 and thus gradually strengthening the whistle, providing an indication that the liquid level is about to reach full.

[0026] Specifically, the lower part of the sound-emitting sleeve 41 is provided with a downwardly protruding sound-emitting protrusion 411, through which the airflow hole 42 passes, and the float valve 5 abuts against the sound-emitting protrusion 411. The sound-emitting protrusion 411 further concentrates the airflow, causing the airflow to impact the edge of the airflow hole 42 more concentratedly, generating stronger vibrations and enhancing the sound intensity.

[0027] Example 2 This embodiment provides a soap refill device with a full-liquid indicator, such as... Figure 4 As shown, the structure of the soap replenishing device in this embodiment is basically the same as that in Embodiment 1. The difference is that the airflow hole 42 in this embodiment is a conical hole, and the diameter of the upper end of the airflow hole 42 is larger than the diameter of the lower end. The conical airflow hole 42 forms a trumpet shape, which can guide the airflow to accelerate more smoothly, reduce energy loss, and increase the turbulence of the airflow at the outlet, making the sound sharper and longer.

[0028] Example 3 This embodiment provides a soap refill device with a full-liquid indicator, such as... Figure 5As shown, the structure of the soap replenishing device in this embodiment is basically the same as that in Embodiment 1. The difference is that the blowing component in this embodiment includes a reed 43, which is disposed inside the vent 14. When the airflow passes through the vent 14, the airflow directly blows the reed 43, causing it to vibrate. By selecting the material, length, or thickness of the reed 43, the vibration frequency of the reed 43 can be adjusted to produce sounds of different frequencies, generating a crisp buzzing sound. When the float valve 5 is about to seal the vent 14, the airflow speed continuously increases, and the reed 43 vibrates most strongly, gradually reaching a high volume value, thus providing an early warning that the soap is about to be full.

[0029] Example 4 This embodiment provides a soap refill device with a full-liquid indicator, such as... Figure 6 As shown, the structure of the soap replenishing device in this embodiment is basically the same as that in Embodiment 1. The difference is that the blowing component in this embodiment includes a whistle 44, which is fixedly installed on the storage tank 1. The air inlet of the whistle 44 is connected to the upper end of the exhaust port 14. The whistle 44 is fixed to the tank cover 12 by snap-fit, threaded connection, or hot-melt welding, which facilitates production assembly and simplifies the production process. When the airflow enters the whistle 44 from the exhaust port 14, the cavity and vibrating plate or lip structure inside the whistle 44 cause the airflow to resonate and vibrate, producing a typical whistling sound. The whistle 44 is a prefabricated acoustic element, and its sound production principle is based on Helmholtz resonance or edge tone effect, producing a loud and easily identifiable sound.
