Description

Technical Field

[0001] The utility model relates to the field of water purification equipment, in particular to a water level detection unit of water purification equipment. Background Art

[0002] Water purification equipment uses a filter to purify water for human consumption. To make it portable, it also includes a water storage container to store the purified water, ensuring a large supply. The water purification equipment also needs to detect the amount of water in the container to determine when to aerate and refill the water. Therefore, the water storage container must be equipped with a water level detection unit. This unit detects the water level in the container and, therefore, the amount of water in the container.

[0003] The water level detection unit includes a water level pipe connected to the water storage container and a water level sensor mounted on the pipe. The pipe is vertically arranged with its bottom connected to the bottom of the water storage container. Under the influence of the water pressure in the water storage container, the water level in the pipe rises and falls synchronously with the water level in the water storage container. The sensor detects the water level changes in the pipe and thus determines the water level in the water storage container and the amount of water in the water storage container. However, as the water level changes, the air pressure in the pipe also changes, so the pipe also needs to be connected to the atmosphere.

[0004] Because of the fear that the water in the water level pipe will overflow from the connecting port and wet the inside of the equipment when connected to the atmosphere, causing a safety hazard, the existing technology uses a water pipe to connect the connecting port to the drainage component to achieve atmospheric connection through the drain port. However, sometimes due to excessive pressure in the pipe, too much water overflows and leaks from the drain port, and even mixes into the outlet water when the drain port is discharging water normally, causing a certain impact. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a water level detection unit for a water purification device.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A water level detection unit of a water purification device includes a water level pipe connected to a pure water tank, the water level pipe is erected on the side of the pure water tank and is provided with a water joint at the bottom thereof and is connected to the bottom of the pure water tank through a pipe, the top of the water level pipe is connected to an exhaust component, the exhaust component is provided with an exhaust port and the exhaust port is covered with a waterproof breathable membrane, and the interior of the water level pipe is connected to the atmosphere through the waterproof breathable membrane.

[0008] The exhaust component is fixed on the top of the water level pipe.

[0009] The exhaust component is integrally arranged on the top of the water level pipe.

[0010] The exhaust component is arranged separately from the water level pipe, and the exhaust component is located above the top of the water level pipe and is connected through a pipeline.

[0011] There is a lateral distance between the arrangement position of the exhaust component and the water level pipe.

[0012] The exhaust component is also connected to the raw water tank or the ice tank.

[0013] The exhaust port is arranged upward, and is located on the top surface of the highest point of the exhaust component.

[0014] The beneficial effects of the present invention are as follows: the present invention abandons the previous air pressure balancing structure in which the air vent water pipe is connected to the drainage component, and balances the air pressure of the water level pipe by arranging an exhaust component. The exhaust component uses a waterproof breathable membrane to achieve ventilation of the exhaust port. The waterproof breathable membrane can effectively intercept moisture and only allows air to pass through, thereby achieving exhaust and air intake of the exhaust component and balancing the air pressure of the water level pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Figure 1 It is a structural diagram of the first embodiment of the utility model;

[0017] Figure 2 It is a structural diagram of the second embodiment of the utility model;

[0018] Figure 3 It is a disassembled schematic diagram of the second embodiment of the present utility model. DETAILED DESCRIPTION

[0019] Reference Figures 1 to 3 A water level detection unit of a water purification equipment includes a water level pipe 2 connected to a pure water tank 1, the water level pipe 2 is erected on the side of the pure water tank 1 and is provided with a water joint 3 at the bottom, which is connected to the bottom of the pure water tank 1 through a pipeline, and the top of the water level pipe 2 is connected to an exhaust component 4, the exhaust component 4 is provided with an exhaust port 41 and the exhaust port 41 is covered with a waterproof breathable membrane 42, the interior of the water level pipe 2 is connected to the atmosphere through the waterproof breathable membrane 42, the waterproof breathable membrane 42 can effectively intercept moisture and only allow air to pass through, thereby realizing the exhaust and air intake of the exhaust component 4 and balancing the air pressure of the water level pipe 2.

[0020] The exhaust component 4 can be arranged relative to the water level pipe 2 according to needs, or can be an independent component or fixed on the water level pipe 2 or arranged integrally with the water level pipe 2.

[0021] When the exhaust component 4 is fixed on the top of the water level pipe 2, as shown in FIG. Figure 1 As shown, the top of the water level pipe 2 is opened to form an opening, and the exhaust component 4 serves as a cover body to seal and fix on the opening.

[0022] When the exhaust component 4 is integrally provided on the top of the water level pipe 2 (not shown in the figure), the exhaust component 4 can be formed by ultrasonic welding or integrally cast with the water level pipe 2, and then the waterproof breathable membrane 42 is installed.

[0023] When the exhaust component 4 is arranged as an independent component and separated from the water level pipe 2, as shown in FIG. Figure 2 As shown, the exhaust component 4 is located above the top of the water level pipe 2 and is connected to it via a pipe. In this case, the exhaust component 4 can also be used as a vent for other modules within the water purification equipment, such as the raw water tank or ice bladder. There is also a lateral distance between the exhaust component 4 and the water level pipe 2. That is, the exhaust component 4 is not arranged on the same axis as the water level pipe 2, which creates a distance between the exhaust component 4 and the top of the water level pipe 2, making it more difficult for water to reach the exhaust component 4.

[0024] Preferably, the exhaust port 41 is arranged upward and is located on the top surface of the highest point of the exhaust component 4 , so as to exhaust and ventilate at the highest point and reduce the possibility of the water level reaching the exhaust port 41 .
