Description

Technical Field

[0001] This utility model relates to the field of water filtration device technology, and more specifically, to a water filter. Background Technology

[0002] As we all know, although tap water undergoes sterilization and disinfection treatment after leaving the water treatment plant, it is subject to secondary pollution after passing through the pipe network for many years. At the same time, tap water contains a large amount of residual chlorine. This residual chlorine can penetrate the cell walls of living organisms such as algae and bacteria, oxidizing their enzyme systems (enzymes are biological catalysts) and rendering them inactive, thus hindering their life activities and causing them to die. Residual chlorine is also seriously harmful to the human body. It can cause dry, brittle, and split ends in hair, and can also cause skin bleaching, peeling, and intensely itchy skin allergies. When heated, chlorine reacts with organic matter in the water to produce carcinogenic substances such as chloroform. Therefore, filtering and purifying tap water before use is extremely important. Utility Model Content

[0003] This utility model overcomes the shortcomings of the prior art. Its structure is reasonably designed, making it easy to quickly assemble onto the corresponding water outlet device. The filter element is easy to replace, and the sensor indicator component can remind consumers to replace the filter element in time.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-13As shown, a water filter includes: an inlet / outlet base 1 having at least one inlet hole 11 and at least one outlet hole 12; and a sensing and indicating assembly 2, which includes a circuit board 21 on the inlet / outlet base 1, a sensing chip 22 on the circuit board 21, an indicating element and a counter on the circuit board 21, an abutment block 3 on the inlet / outlet base 1 that can move towards or away from the inlet / outlet base 1, an elastic element 23 installed in the inlet / outlet base 1, and a sensing element 24, wherein when the abutment block 3 abuts against the inlet / outlet base 1, one end of the sensing element 24 abuts against... The other end of the elastic element 23 abuts against the abutting block 3; the housing 4 is mounted on the inlet / outlet water seat 1; the filter element 5 is located inside the housing 4 and mounted on the inlet / outlet water seat 1, abutting against the abutting block 3, and its interior has an inlet cavity 51 communicating with the inlet hole 11, forming an outlet cavity 52 communicating with the outlet hole 12 between the filter element 5 and the housing 4. When the filter element 5 and the housing 4 are installed on the inlet / outlet water seat 1, the filter element 5 abuts against the abutting block 3, causing the abutting block 3 to abut against the inlet / outlet water seat 1, and at this time the elastic element 23 is compressed. When the filter element 5 is replaced, the abutting block 3 moves away from the inlet / outlet water seat 1. When the water base 1 moves, the elastic element 23 extends, causing the position between the sensing element 24 and the sensing chip 22 to change. At this time, the counter restarts, and when the counter finishes counting, the indicator element emits or changes the indicator signal. The indicator element is set as a light-emitting element, and the housing 4 is light-transmitting. The water inlet 11 is located in the center of the water base 1, and multiple water outlets 12 are arranged around the outer periphery of the water inlet 11. The abutment block 3 is partially located in the water inlet 11, and the abutment block 3 is provided with a connecting hole 31 that communicates with the water inlet 11 and the water inlet cavity 51. The water base 1 is far from the water inlet 1. A sealing mounting base 6 is provided on the side away from the filter element 5. The sealing mounting base 6 is provided with a mounting cavity 61, which is connected to the water outlet 12. The sealing mounting base 6 is fixedly connected to an inlet and outlet water pipe 7. The inlet and outlet water pipe 7 has an inlet channel 71 that is connected to the water inlet 11 and an outlet channel 72 that is connected to the mounting cavity 61. The circuit board 21 is provided on the sealing mounting base 6. An installation pipe 8 is sealed on the side of the inlet and outlet water base 1 away from the filter element 5. The installation pipe 8 is fixedly connected to a mounting body 9. Both the installation pipe 8 and the mounting body 9 are located on the outer periphery of the inlet and outlet water pipe 7.

[0032] By adopting the above technical solution, the water filter of this utility model can be used on kitchen sinks or water outlet devices such as showers, mainly for filtering water. The following description uses installation on a kitchen sink as an example.

[0033] The main innovation of this utility model lies in the design of the structure of the inlet / outlet water base 1, the component composition of the sensing indicator assembly 2, and the positioning and fitting structure of the filter element 5. Specifically, the sensing chip 22 can be a Hall chip, and the sensing element 24 is a magnet. Of course, the sensing chip 22 and the sensing element 24 can also adopt other matching distance-changing sensing components, such as position sensor assemblies. The indicator element and counter are not shown in the attached drawings, but it can be seen that the indicator element and counter can be integrated on the circuit board 21. The indicator element can be a light-emitting element or a light-generating element; when a light-emitting element is used, the corresponding housing 4 is light-transmitting. The circuit board 21 is set on the sealed mounting base 6. Specifically, the circuit board 21 is set in a dry environment, that is, in a position outside the inlet / outlet water passage, or the circuit board 21 is waterproofed.

[0034] Specifically, in practical applications, existing sinks typically include pull-out or non-pull-out faucets, vegetable washing outlets 12, etc. The water filter of this invention is installed on the sink, connected to the pipes below the sink via the mounting base 9. After installation, only the outer casing protrudes above the sink. Because the casing is translucent, the inlet and outlet water bases 1 are also visible. During water filtration, water enters the inlet chamber 51 through the inlet channel 71 of the inlet / outlet pipe 7 via the inlet hole 11. It then passes through the filter element 5 and flows out through the outlet chamber 52, the outlet hole 12, the mounting chamber 61, and the outlet channel 72. The flowing water then reaches the faucet or vegetable washing outlet 12, thus achieving the function of water filtration.

[0035] By setting the sensing indicator component 2, the counter will prompt the user to replace the filter element 5 by changing the light or lighting up after counting. Replacing the filter element 5 is also quite convenient. In this specific embodiment, the housing 4 is threaded onto the inlet / outlet water base 1. Simply unscrew the housing 4; the outer circumference of the housing 4 has raised strips for easy rotation. Then, remove and replace the filter element 5. The filter element 5 can also be threaded onto the inlet / outlet water base 1 or tightly fitted. When the filter element 5 is removed, the elastic element 23 will release its compression, and the sensing chip 22 will detect the change in position of the sensing element 24, causing the counter to restart, thus providing an indication for the next time the filter element 5 needs to be replaced.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
