[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] This case involves a filter element 5, such as Figure 1-2 As shown, it includes a core body 51 and a base 52 that are coaxially connected. The core body 51 can be a common accessory on the market, which has an axial and radial direction. The two ends of the core body 51 in the axial direction are an open end 511 and a closed end 512, respectively, and the core body 51 is provided with a filter mesh 513 for passing water in the radial direction.

[0030] The base 52 has an axial direction coaxial with the core body 51, and the base 52 has a connecting portion 521, a cavity 522 and a seat body portion 523 in sequence along the axial direction. In a specific embodiment, the connecting portion 521 is connected to the seat body portion 523 and the cavity 522 is formed therebetween. The connecting portion 521 of the base 52 is connected to the closed end 512 of the core body 51, the cavity 522 has a radial water hole 5221 for passing water in a radial direction, and the seat body portion 523 has an axial water hole 5231 communicating with the cavity 522.

[0031] The filter element of the present application is designed as a novel structure of a core body 51 and a base 52 which are coaxially connected. With the help of the base 52, the water inlet and outlet of the existing filter element universal accessories are cleverly converted from vertical to coaxial. The filter element 5 can be easily installed with the housing through the base 523. The filter thus constructed has a coaxial water inlet and outlet (such as Figure 5 As shown in the figure, it can realize the application of direct coaxial connection with relevant external interfaces, which is highly practical. For example, when applied to angle valves, the filter angle valve has excellent coaxial inlet and outlet water filtering effect. The overall structure is very simple, maintaining the triangular characteristics of the angle valve, and the installation and disassembly are also very convenient and efficient.

[0032] Preferably, the connection part 521 and the closed end 512 of the core body 51 are threadedly connected. Specifically, a core thread 5121 is provided on the end of the closed end 512, and a connecting thread 5211 is provided on the connection part 521. The core thread 5121 and the connecting thread 5211 are connected to each other, so that the core body 51 and the base 52 can be disassembled and assembled. The core thread of the existing filter element universal accessories is a left-handed thread. Here, preferably, the core thread 5121 and the connecting thread 5211 are left-handed threads.

[0033] Preferably, the connecting portion 521 is a connecting ring, the seat body 523 is a seat ring, the connecting ring 521 and the seat ring 523 are connected by a connecting rib 524 and the cavity 522 is formed inside. The outer diameter of the seat body 523 is larger than the outer diameter of the connecting portion 521, which is conducive to the formation of an axial water passage in the peripheral space of the filter element and the conversion effect of the water drainage direction. The connecting rib 524 has two oppositely arranged ones, and the corresponding radial water holes 5221 have two oppositely arranged ones.

[0034] Preferably, the seat body 523 is provided with an external structure for connecting with an external structure, and a specific implementation of the external structure is an external thread 5232 provided on the seat body 523.

In the housing 6, there is a gap between the portion of the filter core 5 from the filter mesh 513 to the radial water hole 5221 and the inner wall of the housing 6 to form a water passage 61. Water enters from the opening end 511 of the core body 51, enters the water passage 61 after being filtered through the radial filter hole 513, then enters the cavity 522 in the reverse direction through the radial water hole 5221, and finally exits through the axial water hole 5231. Thus, the filter realizes the coaxial inflow and outflow of water, thereby achieving the effect of holding scale and filtering water. At the same time, the filter can be disassembled and installed, which is very convenient for cleaning.
