[0030] The following will further elaborate on the present utility model in conjunction with the attached Figures 1-6 drawings.
[0031] An embodiment of the present utility model discloses a structure for mixing filter elements of a water purifier.
[0032] It includes a cover 1 and a positioning plate 2. One side of the cover 1 is fixedly connected with a connecting pipe 3, and the connecting pipe 3 is used to connect the water outlet pipe or the water inlet pipe. On the other side of the cover 1, there is a groove, and a sealing rubber ring and a filter cartridge are placed in the groove. The outer surface of the cover 1 is fixedly connected with a cage plate 7. The cage plate 7 is used to protect the outer surface of the cover 1 and also serves as a rib plate of the cover 1 to strengthen the strength of the cover 1. The outer surface of the connecting pipe 3 penetrates through the inside of the cage plate 7.
[0033] The groove includes a stepped groove 4 and a through groove 5. The stepped groove 4 is composed of circular through grooves of different sizes. One end of the through groove 5 close to the connecting pipe 3 is conical, and one end close to the cylindrical groove 1 is in the shape of a circular through groove. One end of the through groove 5 is located inside the stepped groove 4, and the other end of the through groove 5 is fixedly connected with a reinforcing plate 6. The reinforcing plate 6 isolates the filter element from the inner wall of the cover 1 to prevent the filter element from blocking the connecting pipe 3.
[0034] One side of the positioning plate 2 is fixedly connected to one side of the cage plate 7. The positioning plate 2 is in the shape of a bent plate. The bent positioning plate 2 can wrap the connecting pipe 3 to the greatest extent, thereby protecting the water inlet pipe or the water outlet pipe. The angle between the two ends of the positioning plate 2 is α, and α = 90°. At the same time, the positioning plate 2 with a notch is also convenient for manual screwing, so as to drive the cover 1 to rotate, adjust the direction of the positioning plate 2, and it is also convenient to pick up and press the positioning plate 2.
[0035] The connecting pipe 3 is located inside the positioning plate 2. The positioning plate 2 protects the connecting pipe 3. The length of the connecting pipe 3 is greater than the length of the positioning plate 2. The outer end of the connecting pipe 3 is just convenient for the water inlet pipe or the water outlet pipe to be connected to the connecting pipe 3.
[0036] The inside of the connecting pipe 3, the stepped groove 4, the through groove 5 and the reinforcing plate 6 are connected. When the filtered liquid enters the connecting pipe 3 from the filter element, it needs to flow into the connecting pipe 3 through the inside of the stepped groove 4, the through groove 5 and the reinforcing plate 6.
[0037] The inner diameters of the stepped groove 4 are arranged from small to large, including a cylindrical groove 1, a cylindrical groove 2, a cylindrical groove 3 and a cylindrical groove 4. The cylindrical groove 1, the cylindrical groove 2, the cylindrical groove 3 and the cylindrical groove 4 form a step. The diameter of the through groove 5 is smaller than the diameter of the cylindrical groove 1. One end of the through groove 5 is located inside the cylindrical groove 1. Matching with the stepped groove 4, it is a little smaller, so as to adapt to the filter element. The gap between the through groove 5 and the cylindrical groove 1 can also be used to place the sealing rubber ring.
[0038] On the side of the cover 1 away from the connecting pipe 3, there are trapezoidal grooves 8 arranged in a circumferential array. The outer surface of the filter cartridge is provided with convex grooves adapted to the trapezoidal grooves 8. Thus, after one end of the filter cartridge enters the inside of the trapezoidal grooves 8, the outer surface of the filter cartridge is clamped with the trapezoidal grooves 8.
[0039] The interior of the reinforcing plate 6 is provided with fan-shaped grooves arranged in a circumferential array. The fan-shaped grooves are fan-shaped through grooves. After the filter element touches the top of the reinforcing plate 6, liquid can pass through the fan-shaped grooves and enter the interior of the communicating pipe 3.
[0040] The implementation principle of a water purifier filter element mixing structure according to an embodiment of the present invention is as follows:
[0041] According to the number of filter elements used in the water purifier, different numbers of covers 1 are installed in the water purifier. One end of the filter cartridge is inserted into the interior of the cover 1, and the outer surface of the filter cartridge is clamped in the trapezoidal groove 8. After each filter element is assembled, the cover 1, the filter cartridge and the filter element can be installed in the water purifier. For filter elements of the same material, the positioning plates 2 are angled towards one position. When another filter element of different material is assembled, during installation, the positioning plates 2 are angled towards other positions. When the filter element is damaged, it can also be instantly judged according to the angle orientation of the positioning plates 2 what material of filter element needs to be replaced. At the same time, all the covers 1 are of the same specification, and only one spare cover 1 needs to be prepared. When the cover 1 is damaged, it can be directly replaced without searching for the model on site and then purchasing the cover 1.
[0042] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention shall be covered within the protection scope of the present invention.
