[0029] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a convenient installation filter for drinking water, comprising at least two mounting seats 1 and at least one connector. Each mounting seat 1 has an inlet pipe 11 and an outlet pipe 12. Each connector comprises a pipe body 2, two fixing members 3 and two locking members 4. The two fixing members 3 are respectively mounted at both ends of the pipe body 2. One end of the two locking members 4 respectively passes through the two fixing members 3 and extends into the pipe body 2. One end of each locking member 4 has a plurality of elastic parts 41, and the inner surface of each elastic part 41 is provided with a protruding block 411. When the connector is connected to the inlet pipe 11 or / and the outlet pipe 12, the protruding block 411 abuts against the outer wall of the inlet pipe 11 or / and the outer wall of the outlet pipe 12.

[0031] In specific applications, it is only necessary to insert the water inlet pipe 11 and the water outlet pipe 12 of the two mounting seats 1 to be assembled through the locking piece 4 and into the pipe body 2 respectively. The raised block 411 can clamp the water inlet pipe 11 and the water outlet pipe 12 under the elastic action of the elastic part 41, thereby realizing the quick connection between the connecting head and the mounting seat 1, thereby realizing the connection between the two mounting seats 1.

[0032] Take the example of a convenient installation filter for drinking water with two mounting seats 1. Correspondingly, there are also two filter cartridges 6. The two filter cartridges 6 are detachably installed in the two filters. When filtering, water enters one filter cartridge 6 through the water inlet pipe 11 of one mounting seat 1 for the first filtration, and then enters another filter cartridge 6 through the water outlet pipe 12 of one mounting seat 1, the connector and the water inlet pipe 11 of another mounting seat 1 for the second filtration, and then is discharged from the water outlet pipe 12 of another mounting seat 1, thereby achieving the filtration treatment of water. Of course. The number of mounting seats 1 and filter cartridges 6 can be adaptively increased or decreased according to actual needs, and the type of filter cartridge 6 can also be selected according to actual needs, such as the filter cartridge 6 can be one or more of pp cotton filter cartridge 6, granular carbon filter cartridge 6, compressed carbon filter cartridge 6, RO reverse osmosis filter cartridge 6 and activated carbon filter cartridge 6.

[0033] In some preferred embodiments, the protruding block 411 has an inclined surface, and the inclined surface is inclined from the end side of the tube body 2 to the inner side of the tube body 2 in the axial direction of the tube body 2. In a specific application, by providing the protruding block 411 with an inclined surface inclined from the end side of the tube body 2 to the inner side of the tube body 2 in the axial direction of the tube body 2, when connecting the water inlet pipe 11 (or the water outlet pipe 12) and the connector, not only is the insertion more labor-saving, but also the protruding block 411 provides a reverse force after insertion, so that the water inlet pipe 11 (or the water outlet pipe 12) and the connector are firmly connected and not easy to be pulled out.

[0034] In some preferred embodiments, the outer wall of the water inlet pipe 11 and the outer wall of the water outlet pipe 12 are provided with a slot (not shown in the figure), and when the connector is connected to the water inlet pipe 11 and / or the water outlet pipe 12, the protrusion 411 is locked in the slot. In specific applications, by providing the slot on the outer wall of the water inlet pipe 11 and the outer wall of the water outlet pipe 12, the protrusion 32 cooperates with the slot to further improve the firmness of the connection between the water inlet pipe 11 (or the water outlet pipe 12) and the connector.

[0035] In some preferred embodiments, each of the above-mentioned mounting bases 1 has two reinforcement rings 13, and the two reinforcement rings 13 surround the water inlet pipe 11 and the water outlet pipe 12 respectively. When the connector is connected to the water inlet pipe 11 and / or the water outlet pipe 12, the end of the connector extends into the reinforcement ring 13. In specific applications, by arranging two reinforcement rings 13 surrounding the water inlet pipe 11 and the water outlet pipe 12 respectively on the mounting base 1, the strength of the water inlet pipe 11 (or the water outlet pipe 12) and the connector after being connected can be improved, so as to prevent the connection between the water inlet pipe 11 (or the water outlet pipe 12) and the connector from being easily broken.

[0036] In some preferred embodiments, each of the fixing members 3 has a first limiting portion 31, the outer side wall of the other end of each locking member 4 has a second limiting portion 42, the outer side wall of each elastic portion 41 has a third limiting portion 43, the first limiting portion 31 is located between the second limiting portion 42 and the third limiting portion 43, and the second limiting portion 42 and the third limiting portion 43 are both movably abutted against the first limiting portion 31. In specific applications, the first limiting portion 31, the second limiting portion 42 and the third limiting portion 43 cooperate with each other to prevent the locking member 4 from falling off the connector.

[0037] In some preferred embodiments, the first limiting portion 31 is provided with a limiting groove 311 that matches the shape of the third limiting portion 43, and when the third limiting portion 43 abuts against the first limiting portion 31, the third limiting portion 43 is located in the limiting groove 311. In specific applications, by providing the limiting groove 311 that matches the shape of the third limiting portion 43 on the first limiting portion 31, the limiting groove 311 can play an axial limiting role on the multiple elastic portions 41, thereby ensuring that the connector is firmly connected to the water inlet pipe 11 (or the water outlet pipe 12).

[0038] In some preferred embodiments, the pipe body 2 has a first straight section 21, a second straight section 22 and a third straight section 23 connected in sequence, the inner diameter of the first straight section 21 is equal to the inner diameter of the third straight section 23, and both are larger than the inner diameter of the second straight section 22; a sealing ring 5 is provided in the first straight section 21 and the third straight section 23, and when the connector is connected to the water inlet pipe 11 or / and the water outlet pipe 12, the sealing ring 5 is sleeved on the water inlet pipe 11 or / and the water outlet pipe 12. In specific applications, the sealing ring 5 can seal the gap between the water inlet pipe 11 (or the water outlet pipe 12) and the first straight section 21 (or the third straight section 23) to prevent water leakage. Specifically, the end of the water inlet pipe 11 away from the mounting seat 1 passes through the first straight section 21 and extends into the second straight section 22, and the end of the water outlet pipe 12 away from the mounting seat 1 passes through the third straight section 23 and extends into the second straight section 22.

[0039] In some preferred embodiments, a limiting ring 221 is provided on the inner side wall of the middle portion of the second straight section 22. When the connector is connected to the water inlet pipe 11 and / or the water outlet pipe 12, the limiting ring 221 abuts against the water inlet pipe 11 and / or the water outlet pipe 12. In specific applications, by providing the limiting ring 221 on the inner side wall of the middle portion of the second straight section 22, the lengths of the water inlet pipe 11 and the water outlet pipe 12 inserted into the connector are equal, thereby avoiding the situation that the water inlet pipe 11 and the water outlet pipe 12 are inserted into the connector with different lengths, which is prone to water leakage.

[0040] In some preferred embodiments, the inner diameter of the above-mentioned limiting ring 221 is greater than or equal to the inner diameter of the water inlet pipe 11 or the water outlet pipe 12, and smaller than the outer diameter of the water inlet pipe 11 or the water outlet pipe 12. In practical applications, by designing the inner diameter of the limiting ring 221 to be greater than or equal to the inner diameter of the water inlet pipe 11 or the water outlet pipe 12 and smaller than the outer diameter of the water inlet pipe 11 or the water outlet pipe 12, it can not only play a limiting role on the water inlet pipe 11 and the water outlet pipe 12, but also avoid the limiting ring 221 from affecting the water flow.

[0041] In some preferred embodiments, the outer side walls of both ends of the tube body 2 are provided with grooves 24, and the inner side walls of each fixing member 3 are provided with a protrusion 32, which is clamped in the groove 24. In specific applications, the fast connection between the fixing member 3 and the tube body 2 can be achieved by matching the groove 24 with the protrusion 32.

[0042] To summarize, in one or more embodiments of the present invention, the convenient installation filter for drinking water of the present invention improves the structure of the connecting head, that is, by providing inwardly protruding protrusions on the inner surfaces of multiple elastic portions at one end of the locking piece, so that the water inlet pipe and the water outlet pipe can be inserted into the connecting head and clamped to complete the assembly. Compared with the use of a double-headed threaded pipe to connect two adjacent mounting seats, the time required for screwing the double-headed threaded pipe is saved, thereby greatly improving the production efficiency.

[0043] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
