Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a water tank cleaning device. Background Art

[0002] With the improvement of modern people's quality of life, various drinking water treatment equipment has entered the home, and people's experience requirements for drinking water treatment equipment are increasing. Although the municipal tap water used in drinking water treatment equipment is a water source that has been preliminarily treated and its quality is better than that of water directly obtained from lakes or underground, there are still a large number of bacteria in it, which endanger human health and safety to a certain extent. The pure water tank, clean water tank, raw water tank and other water storage containers on common water dispensers, water purifiers and other devices on the market are generally installed inside the machine. The environment is mostly dark and humid. After a period of use, it is very easy to nourish microorganisms and residues, which adhere to the inner wall of the water tank, causing secondary pollution to the clean water and affecting drinking water health.

[0003] To this end, the prior art usually installs a static ultraviolet (UV) sterilization lamp inside the water tank of the water purifier, and sterilizes with ultraviolet light at regular intervals, thereby inhibiting possible bacterial growth in the water tank. However, in actual situations, the environment inside the water tank is complex and changeable. Factors such as humidity and temperature will affect the spread and sterilization effect of ultraviolet light. Dirt will also accumulate inside the water tank, further affecting the spread of ultraviolet light, and will also cause the water tank (usually made of plastic PP material) to turn yellow and age, causing water pollution and endangering human health. At the same time, the ultraviolet sterilization lamp sterilizes at fixed time intervals, rather than dynamically adjusting according to the actual water quality conditions. This means that even under different water quality conditions, the sterilization lamp will start at the same time, making it difficult to eliminate potential bacteria and viruses.

[0004] Moreover, many consumers are more concerned about the filtering effect and taste of drinking water treatment equipment such as water purifiers when purchasing them, rather than the function of real-time monitoring of the water quality inside the water tank. Real-time monitoring of the water quality inside the water tank requires accurate, stable and reliable sensors and detection equipment to ensure the accuracy of the monitoring results. However, such equipment and systems will inevitably greatly increase the cost of the water purifier, thereby increasing the selling price of the water purifier and affecting consumers' willingness to buy. Therefore, market demand and cost considerations have led manufacturers to ignore the technology of water tank cleaning devices, resulting in existing drinking water treatment equipment usually not having cleaning devices to monitor the water quality inside the water tank. Utility Model Content

[0005] In view of the above technical problems, the utility model proposes a water tank cleaning device, which aims to realize water quality monitoring and timely cleaning of the water tank, while ensuring the cleaning effect of the water tank and saving costs to a certain extent.

[0006] To this end, the present application provides a water tank cleaning device. The water tank includes a tank cover and a tank body.

The cleaning device is fixedly installed inside the tank body, and the light intensity detection device is connected to the cleaning device.

[0007] In some embodiments, a through hole is provided on the bottom surface of the tank body. The light-transmitting structure includes a fixed connecting member and a light-transmitting member.

[0008] In some embodiments, the outer side of the fixed connecting member is in threaded cooperation with the through hole on the bottom surface of the tank body, and the inner side of the fixed connecting member is fixedly connected to the light-transmitting member.

[0009] In some embodiments, a sealing gasket is provided between the inner side of the fixed connecting member and the light-transmitting member.

[0010] In some embodiments, the water tank includes a water inlet valve. The water inlet valve is located at the upper end of the water tank. The water tank cleaning device includes a liquid level switch. The liquid level switch is fixedly installed on the lower surface of the tank cover, and the liquid level switch is connected to the water inlet valve.

[0011] In some embodiments, the liquid level switch includes a highest point and a lowest point. When the liquid level in the water tank is lower than the lowest point of the liquid level switch, the water inlet valve is opened for water replenishment. When the liquid level in the water tank is higher than the highest point of the liquid level switch, the water inlet valve is closed to stop water replenishment.

[0012] In some embodiments, the lamp head of the spotlight is lower than the highest point of the liquid level switch of the water tank.

[0013] In some embodiments, the water tank cleaning device includes a mechanical liquid level switch. The mechanical liquid level switch is installed inside the water tank, and the mechanical liquid level switch is connected to the water inlet valve.

[0016] The beneficial technical effects of the present utility model at least include:

[0017] Since the water tank contains bacteria and their metabolic secretions, water sediments, etc. generated due to factors such as humidity and temperature, the light transmittance of water will inevitably be affected. Therefore, this application adopts a water tank cleaning device, and creatively designs that the spotlight, the light-transmitting structure, and the light intensity detection device are on the same vertical line so that the light source of the spotlight passes through the water inside the water tank and then irradiates on the light intensity detection device through the light-transmitting structure.

[0022] The following explains and illustrates the technical solutions of the embodiments of the present utility model with reference to the drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0023] In the following description, terms indicating orientation or positional relationship such as "inner", "outer", "upper", "lower", "left", "right", etc. are only for convenience in describing embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on the present utility model.

[0024] An embodiment of the present application provides a water tank cleaning device. Please refer to the attached Figure 1 , the water tank includes a tank cover 1 and a tank body 2. The water tank cleaning device includes a spotlight 5, a light intensity detection device 6, and a cleaning device 7. The spotlight 5 is fixedly connected to the tank cover 1. A light-transmitting structure is provided on the bottom surface of the tank body 2. The light intensity detection device 6 is fixedly installed below the light-transmitting structure. The spotlight 5, the light-transmitting structure, and the light intensity detection device 6 are arranged in alignment so that the light source of the spotlight 5 irradiates on the light intensity detection device 6 through the light-transmitting structure. The cleaning device 7 is fixedly installed inside the tank body 2, and the light intensity detection device 6 is connected to the cleaning device 7.

[0025] Optionally, the light intensity detection device 6 in this embodiment includes, but is not limited to, low-cost devices such as photoresistors / photodiodes, light intensity meters / photometers, and PIN photodiodes. Among them, the cleaning device 7 includes, but is not limited to, UV germicidal lamps, motor antibacterial devices, ozone germicidal lamps, etc., as long as it can clean the inside of the water tank in a timely manner according to the detection results of the light intensity detection device 6. This embodiment does not make any limitations in this regard.

[0026] Since the water tank contains bacteria and their metabolic secretions, water sediments, etc. generated due to factors such as humidity and temperature, the light transmittance of water will inevitably be affected. Therefore, the present application adopts a water tank cleaning device, and creatively designs the spotlight 5, the light-transmitting structure, and the light intensity detection device 6 to be on the same vertical line so that the light source of the spotlight 5 passes through the water inside the water tank and then irradiates on the light intensity detection device 6 through the light-transmitting structure. The detection result of the light intensity of the light source emitted by the spotlight 5 read by the light intensity detection device 6 reflects the degree of pollution inside the water tank. This design is not only simple in structure and low in cost, but also more economical for both manufacturers and consumers while maintaining high performance. Moreover, it can effectively judge the degree of pollution inside the water tank according to the change of light intensity, realize the automatic monitoring of the water quality inside the water tank, and combine the connection between the light intensity detection device 6 and the cleaning device 7, so as to dynamically adjust the operation of the cleaning device 7 based on the monitoring results of the light intensity detection device 6 to achieve timely cleaning treatment inside the water tank, thereby overcoming the fixed time and condition limitations of static ultraviolet germicidal lamps and flow-through UV sterilization in the prior art and ensuring the water quality safety inside the water tank.

[0027] On the other hand, in this embodiment, a through hole is provided on the bottom surface of the box body 2. The light-transmitting structure includes a fixed connecting member 8 and a light-transmitting member 9. The fixed connecting member 8 is used to fixedly connect the light-transmitting member 9 in the through hole on the bottom surface of the box body 2. The light intensity detection device 6 is fixedly installed below the light-transmitting member 9. The spotlight 5, the light-transmitting member 9, and the light intensity detection device 6 are arranged in alignment so that the light source of the spotlight 5 irradiates the light intensity detection device 6 through the light-transmitting member 9.

[0028] Among them, the light-transmitting member 9 in this embodiment includes, but is not limited to, transparent glass, acrylic board, lens, optical fiber, etc., as long as it can effectively transmit the light source emitted by the spotlight 5. This embodiment does not make any limitations in this regard.

[0029] Optionally, in this embodiment, a threaded fit can be adopted between the outer side of the fixed connecting member 8 and the through hole on the bottom surface of the box body 2, and the inner side of the fixed connecting member 8 is fixedly connected to the light-transmitting member 9.

[0030] Specifically, the fixed connecting member 8 can be designed as a hollow circular threaded structure. The fixed connecting member 8 is in threaded fit with the through hole on the bottom surface of the box body 2, and the light-transmitting member 9 is designed as a circle matching the hollow in the middle of the fixed connecting member 8.

[0031] Furthermore, a circular gasket with a hole in the middle can be provided between the light-transmitting member 9 and the fixed connecting member 8, which can enhance the fixing effect between the light-transmitting member 9 and the fixed connecting member 8 without affecting the light-transmitting effect of the light-transmitting member 9.

[0032] It can be understood that in this embodiment, through the design of the light-transmitting structure of the fixed connecting member 8 and the light-transmitting member 9 and the alignment of the spotlight 5, the light-transmitting member 9, and the light intensity detection device 6, the light path can be simply and effectively managed, so that the light source of the spotlight 5 directly irradiates the light intensity detection device 6 through the light-transmitting member 9, reducing the loss of light during transmission and improving the light utilization rate. At the same time, since the light intensity detection device 6 is located below the light-transmitting member 9, the compactness of the structure is maintained. Therefore, the light emitted by the spotlight 5 can be received more accurately, and it also has strong adaptability to environmental changes. For example, environmental factors such as the humidity inside the water tank have little impact on the light intensity detection device 6.

[0033] In another embodiment of this specification, please refer to the attached Figure 1 , the water tank includes a water inlet valve 3. The water inlet valve 3 is located at the upper end of the water tank. The water tank cleaning device includes a liquid level switch 10. The liquid level switch 10 is fixedly installed on the lower surface of the tank cover 1, and the liquid level switch 10 is connected to the water inlet valve 3.

[0034] Among them, in the prior art, the water tank of the drinking water treatment device usually has a water inlet pipe fixedly installed at the upper end of the box body 2 and a drain pipe fixedly installed at the bottom end of the box body 2. The water inlet valve 3 is usually installed at the output end of the water inlet pipe, and the drain valve 4 is usually installed at the input end of the drain pipe and is located below the box body 2.

[0035] Furthermore, in this embodiment, the liquid level switch 10 includes a highest point and a lowest point. When the liquid level in the water tank is lower than the lowest point of the liquid level switch 10, the water inlet valve 3 is opened for water replenishment. When the liquid level in the water tank is higher than the highest point of the liquid level switch 10, the water inlet valve 3 is closed to stop water replenishment.

[0036] This embodiment designs a liquid level switch 10 including a highest point and a lowest point in the water tank cleaning device, which can monitor the water level in the water tank in real time, providing a structural basis for first replenishing water to the highest point of the liquid level switch 10 and then dynamically adjusting the operation of the cleaning device 7 based on the monitoring results of the light intensity detection device 6 to achieve the cleaning treatment of the inside of the water tank, and avoiding affecting the cleaning effect or damaging the device due to too low water level.

[0037] In another embodiment of this specification, please refer to the appendix Figure 1 , the lamp head of the spotlight 5 is lower than the highest point of the water tank liquid level switch 10.

[0038] This embodiment designs the lamp head of the spotlight 5 to be lower than the highest point of the water tank liquid level switch 10, so that the light source emitted by the spotlight 5 can directly irradiate in the water, avoiding the situation that part of the light source is reflected or refracted by the water surface when the spotlight 5 irradiates the water surface and the light may deviate from the original path when entering the water tank, minimizing the loss of light during transmission and the possible adverse effects, improving the light utilization rate, and thus improving the accuracy of light intensity detection.

[0039] In another embodiment of this specification, the water tank cleaning device includes a mechanical liquid level switch 11. The mechanical liquid level switch 11 is installed inside the water tank, and the mechanical liquid level switch 11 is connected to the water inlet valve 3.

[0040] Among them, the mechanical liquid level switch 11 in this embodiment includes but is not limited to a mechanical float ball, a pneumatic liquid level switch 10, a lever liquid level switch 10, etc., as long as it can control the opening and closing of the water inlet valve 3 according to the liquid level in the water tank without electricity. This embodiment does not make any limitations in this regard.

[0041] In this embodiment, through the dual water cut-off guarantees of the liquid level switch 10 and the mechanical liquid level switch 11, the overall reliability of the water tank cleaning device is ensured. By way of example, taking the mechanical float ball as the mechanical liquid level switch 11, the mechanical float ball does not require electricity to control the water inlet valve 3. The mechanical float ball floats up and down according to the water level. When the water level in the water tank reaches the highest point of the liquid level switch 10, the float ball will touch the valve closing switch of the water inlet valve 3 to cut off the water inlet source. Therefore, in the case of power fluctuations or interruptions, it can still work normally, avoiding water overflow caused by the overfilling of the water tank, and improving the overall reliability of the water tank cleaning device.

[0042] In yet another embodiment of this specification, the cleaning device 7 is an ultrasonic generator.

[0043] Furthermore, in this embodiment, the water tank includes a drain valve 4. The drain valve 4 is located below the box body 2, and the drain valve 4 is connected to the ultrasonic generator.

[0044] It can be understood that in this embodiment, it is preferred that the cleaning device 7 is an ultrasonic generator. By using the vibration and penetration power of the ultrasonic waves emitted by the ultrasonic generator, the pollutants on the inner wall of the water tank are cleaned. At the same time, after ultrasonic cleaning, by combining the valve opening operation of the drain valve 4, the pollutants cleaned out of the water tank can be discharged. Compared with the existing technologies such as ultraviolet sterilization, it is more efficient and thorough, ensuring the cleaning effect inside the water tank and the drinking water hygiene and safety of users.

In certain environments, multitasking and parallel processing may be advantageous. Similarly, although several specific implementation details are included in the above discussion, these should not be construed as limiting the scope of this disclosure.
