Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the scope of protection of the present utility model.

Please refer to Figures 1 to 3, this utility model provides a technical solution: a deodorant and anti-blocking three-pass filter toilet pipe, including pipe 1, connector 2, connection groove 3, water inlet pipe 4, installation groove 5, installation Block 6, filter element 7, sealing ring 8, grid 9, activated carbon 10, fixed rod groove 11, fixed groove 12, spring 13, fixed rod 14, connecting rod groove 15, connecting rod 16, pressure rod groove 17, and pressure rod 18 , The two ends of the pipe 1 are fixedly connected with the connector 2, the pipe 1 is connected with the water inlet pipe 4, and the inner side of the water inlet pipe 4 is in close contact with the filter element 7 through the sealing ring 8. When the water in the water inlet pipe 4 enters the pipe When it is inside 1, avoid the gap between the water flow filter 7 and the water inlet pipe 4 to directly enter the inside of the pipe 1, so that the water can flow out through the two sides of the pipe 1 after being filtered by the filter element 7, so as to avoid the clogging of the water pipe inside the toilet. The connecting head 2 is provided with a connecting groove 3 on the side away from the pipe 1, and the middle of the top end of the pipe 1 is connected with a water inlet pipe 4, wherein:

A mounting groove 5 is opened in the middle of the top end of the pipe 1, and a mounting block 6 is installed inside the mounting groove 5. Fit, and the maximum outer diameter of the installation block 6 is greater than the inner diameter of the installation groove 5. When the installation block 6 drives the filter element 7 into the pipe 1 and the water inlet pipe 4, the smaller outer diameter of the installation block 6 enters the installation groove 5 At the same time, the bottom of the mounting block 6 can be pressed against the bottom of the pipe 1 to prevent the mounting block 6 from completely entering the inside of the pipe 1. Inside the water inlet pipe 4, the mounting block 6 and the outside of the filter element 7 are sheathed with a sealing ring 8, the sealing ring 8 of the filter element 7 is located inside the water inlet pipe 4, and a net frame 9 is fixed at the top of the filter element 7; The mesh diameter of the net frame 9 is smaller than the particle size of the activated carbon 10 to prevent the activated carbon 10 from flowing out of the filter element 7. The activated carbon 10 can absorb the odor in the pipe 1 and facilitate the deodorization of the pipe 1. Activated carbon 10 is filled inside, and fixed rod grooves 11 are opened on both sides of the installation block 6 close to the pipe 1;

The pipe 1 is provided with a fixing groove 12 on one side close to the fixing rod groove 11, the spring 13 is fixed inside the fixing rod groove 11, and the spring 13 is connected to the fixing rod 14 near the opening side of the fixing rod groove 11. The top of one end of the fixed rod 14 away from the spring 13 is curved, and the fixed rod 14 is elastically connected to the mounting block 6 through the spring 13. The fixed rod 14 is squeezed into the fixed rod groove 11, and the spring 13 is compressed. When the mounting block 6 is pressed against the bottom of the pipe 1, the fixed rod groove 11 and the fixed groove 12 are just aligned, and the spring 13 drives the fixed rod 14 into the fixing The inside of the groove 12 is convenient for installing the filter element 7. The mounting block 6 is provided with connecting rod grooves 15 on both sides of the inside. The connecting rod groove 15 communicates with the fixing rod groove 11, and the fixing rod 14 is close to the connecting rod. A connecting rod 16 is fixed on one side of the groove 15, a pressure rod groove 17 is penetrated through the bottom of the mounting block 6 near the connecting rod groove 15, and a pressure rod 18 is fixed on the side of the connecting rod 16 near the pressure rod groove 17, so The length of the pressure rod 18 on the outside of the mounting block 6 is longer than the length of the fixed rod 14 entering the fixing groove 12. When the filter element 7 needs to be replaced, press the pressure rods 18 on both sides, and the pressure rod 18 drives the fixed rod 14 to the direction through the connecting rod 16. The fixed groove 12 is moved outside, so that the fixed rod 14 can be completely moved out of the inside of the fixed groove 12, and then the mounting block 6 is removed. The mounting block 6 drives the filter element 7 to move out of the pipe 1, facilitating the removal of the filter element 7. One end of the connecting rod 16 extends through the inside of the mounting block 6 to the outside.

Working principle: When the deodorant and anti-blocking three-pass filter toilet tube is used, the water flowing through the filter element 7 will flow out through both sides of the pipe 1 to avoid clogging of the water pipe inside the toilet. At the same time, the activated carbon 10 can treat the odor in the pipe 1 When the filter element 7 needs to be replaced, press the pressure rods 18 on both sides. The pressure rod 18 drives the fixed rod 14 to move out of the fixed groove 12 through the connecting rod 16, so that the fixed rod 14 can be completely moved. Remove the inside of the fixed groove 12, and then remove the installation block 6. The installation block 6 drives the filter element 7 out of the pipe 1 to facilitate the removal of the filter element 7. After that, the filter element 7 is separated from the installation block 6, and the installation block 6 to be installed is taken out. The installation block 6 is fixedly connected with the filter element 7 by gluing, and then the installation block 6 drives the filter element 7 into the inside of the pipe 1 and the water inlet pipe 4, and the smaller outer diameter of the installation block 6 enters the inside of the installation groove 5, and the pipe 1 resists The curved surface of the fixed rod 14 causes the fixed rod 14 to be squeezed into the inside of the fixed rod groove 11, and the spring 13 is compressed. When the mounting block 6 resists the bottom of the pipe 1, the fixed rod groove 11 and the fixed groove 12 are just aligned, and the spring 13 The fixed rod 14 is driven to enter the inside of the fixed groove 12 to facilitate the installation of the filter element 7.

Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it will be understood that various changes and modifications can be made to these embodiments without departing from the principle and spirit of the present invention. , Substitutions and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
