Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, and relates to a filter element, specifically a filter element introduction and error-proof structure. Background Technology

[0002] In response to the problem of secondary pollution of tap water and the presence of harmful substances in tap water due to raw water pollution, more and more water purifiers are being used.

[0003] A water purifier, also called a water filter machine or water purifier, is a water treatment device that deeply filters and purifies water according to usage requirements. Its function is to remove suspended solids, heavy metals, bacteria, viruses, residual chlorine, sediment, rust, microorganisms, and other contaminants from the water. During installation, the filter cartridge's water path needs to be connected to the water distribution plate to ensure smooth water flow. Therefore, installation is relatively complicated, and it is crucial to ensure the correct water path connection. If the filter cartridge's inlet angle is off, it will cause incorrect water flow, affecting normal water output. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a filter cartridge introduction error prevention structure that is simple in structure and easy to operate, in view of the above-mentioned technical status.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a filter element introduction anti-mistake structure, including a filter element and a water channel plate, characterized in that: a water channel adapter plate is fixed on the water channel plate, the water channel plate is connected to the end of the filter element through the water channel adapter plate, at least one or more guide posts are protruding on the water channel adapter plate, and corresponding guide holes are opened on the mating surface of the filter element, and the water channel plate adapter plate is aligned with the filter element and introduced through the cooperation of the guide posts and guide holes.

[0006] Furthermore, the water circuit plate has a recessed groove on one side corresponding to the filter element, in which the water supply adapter plate is embedded. The water circuit plate adapter plate is embedded in the groove and fixed to the water circuit plate, and the guide post protrudes from the water circuit adapter plate near the edge.

[0007] Furthermore, the water circuit board has three water circuits that are respectively connected to the inlet, outlet and wastewater discharge port of the filter element. Correspondingly, the water circuit adapter plate has three hollow cylinders that are inserted into the inlet, outlet and wastewater discharge port of the filter element, and a water stop valve core is installed in the hollow cylinder.

[0008] Furthermore, the three hollow cylinders are arranged radially on the water channel adapter plate, and the guide post protrudes from the water channel adapter plate and is located on one side of the three hollow cylinders.

[0009] Preferably, both the guide post and the guide hole are a single unit.

[0010] Finally, the guide post is arranged in a straight line with the three hollow cylinders.

[0011] Compared with existing technologies, the advantages of this invention are as follows: the water circuit adapter plate is fixed to the water circuit plate, a guide post is protruding on the water circuit adapter plate, and a corresponding guide hole is opened on the mating surface of the filter element. The filter element can only fully fit with the water circuit adapter plate and conduct water when it is in place after being guided into the guide hole by the guide post; otherwise, it cannot be introduced. This invention has a simple structure, is easy to operate, and effectively prevents the filter element from being introduced into the water circuit adapter plate at other angles, thus preventing incorrect water flow and ensuring normal water output. Attached Figure Description

[0012] Figure 1 This is a cross-sectional view of an embodiment of the present utility model;

[0013] Figure 2 This is a cross-sectional view of an embodiment of the present invention with the filter element and water circuit board separated.

[0014] Figure 3 This is an exploded view of an embodiment of the present utility model. Detailed Implementation

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

[0016] like Figure 1 , 2 As shown in Figure 3, a filter cartridge introduction anti-mistake structure includes a filter cartridge 1 and a water channel plate 2. A water channel adapter plate 3 is fixed on the water channel plate 2. The water channel plate 2 is connected to the filter cartridge 1 through the water channel adapter plate 3. A guide post 31 is protruding on the water channel adapter plate 3. A corresponding guide hole 11 is opened on the mating surface of the filter cartridge 1. The water channel plate adapter plate 3 is aligned with the filter cartridge 1 and introduced through the cooperation of the guide post 31 and the guide hole 11.

[0017] The specific structure is as follows: A groove 21 for the water supply adapter plate 3 is recessed on one side of the water circuit plate 2 corresponding to the filter element 1. The water circuit adapter plate 3 is embedded in the groove 21 and fixed to the water circuit plate 2 by screws. A guide post 31 protrudes from the water circuit adapter plate 3 near its edge. The water circuit plate 2 has three water channels that connect to the inlet, outlet, and wastewater discharge outlet of the filter element 1, respectively. Correspondingly, the water circuit adapter plate 3 has three hollow cylinders 32 that insert into the inlet, outlet, and wastewater discharge outlet of the filter element 1. A stop valve core 4 is installed inside each hollow cylinder 32. The three hollow cylinders 32 are arranged radially on the water circuit adapter plate 3, and the guide post 31 protrudes from the water circuit adapter plate 3, located on one side of the three cylinders 32, forming a straight line arrangement. The water circuit structure within the water circuit plate 2, and its connection with the filter element 1, are consistent with existing technology and will not be described further here.

[0018] During installation, the guide post 31 is aligned with the guide hole 11 of the filter element 1, and the three hollow cylinders 32 are aligned with the three interfaces of the filter element and inserted. The filter element 1 can only be fully matched with the water circuit adapter plate 3 and connected to the water circuit plate 2 after the guide post 31 is inserted into the guide hole 11 and is in place. Otherwise, it cannot be inserted.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
