Detailed implementation

[0027] The following further describes the present utility model in conjunction with the embodiments shown in the drawings:

[0028] As Figures 1 to 5 shown, the first embodiment of the present utility model

[0029] An electromagnetic valve water inlet pipe facilitating the installation of a check valve and a filter screen, comprising a valve body 1. One end of the valve body 1 is provided with a water inlet 11, and the other end is provided with a water outlet 12. One side of the valve body 1 is provided with a control port 13. Inside the control port 13, there is an electromagnetic valve capable of controlling the water outlet. Here, the electromagnetic valve acts as a switch and can control whether water can pass through the inside of the control port 13. Inside the valve body 1, there is a valve body installation channel 15. Compared with a common valve body 1, the valve body installation channel 15 inside it is longer. Users can install different filter elements 2, flow regulating elements 3, and check valve elements 4 inside the valve body installation channel 15 according to their own needs. The end of the water inlet 11 is provided with a plurality of annular bosses 111. The outside of the annular bosses is detachably covered with a valve body end cover 5. One end of the valve body end cover 5 is provided with an internal threaded groove 51. This setting is to enable the valve body end cover 5 to be adapted to the water inlet with threads. Among them, the filter element 2 is arranged above the flow regulating element 3, and the check valve element 4 is arranged below the flow regulating element 3. A first sealing ring 6 is arranged between the flow regulating element 3 and the filter element 2. Inside the water inlet 11, there is also a first cylindrical filter screen 14. The side of the first cylindrical filter screen 14 is provided with a first cylindrical boss 141. The first cylindrical boss 141 fits against the valve body installation channel 15. A second sealing ring 7 is arranged between the top of the first cylindrical filter screen 14 and the top of the water inlet 11.

[0030] In the first embodiment, the filter element 2 is a second columnar filter screen 21, and the side of the second columnar filter screen 21 is provided with a second columnar boss 211, and the second columnar boss 211 is attached to the valve body installation channel 15. The check valve element 4 includes a first annular check valve body 41 and a first check valve end cover 411. The surface of the first annular check valve body 41 is provided with a plurality of first water outlet channels 412. The middle part of the first check valve end cover 411 is provided with a third columnar boss 413, and the third columnar boss 413 is stuck in the middle part of the first check valve end cover 411. The first check valve end cover 411 is arranged near the water outlet. The first check valve end cover 411 is made of deformable silicone or silicone material. After being configured in this way, water will flow downward from the first water outlet channel 412 when flowing from top to bottom. During the flow, the water will impact the first check valve end cover 411 to deform it, so that a gap exists between the first check valve end cover 411 and the bottom of the first annular check valve body 41. However, when water flows back from bottom to top, the water will impact the first check valve end cover 411 to make it fit firmly to the bottom of the first annular check valve body 41, and the gap disappears, thereby realizing the control of water reflux.

[0031] like Figures 6 to 10 As shown, the second embodiment of the utility model is different from the first embodiment in that a different filter element 2 and a check valve element 4 are replaced, and the other structures are the same.

[0032] The filter element 2 used is a third columnar filter screen 22, the height of the third columnar filter screen 22 is less than the height of the second columnar filter screen 21, and a fourth columnar boss 221 is provided on the side of the third columnar filter screen 22, and the fourth columnar boss 221 is attached to the valve body installation channel 15.

[0033] One of the check valve elements 4 includes a second columnar check valve body 42 and a second check valve end cover 421, wherein the second check valve end cover 421 is inserted into the interior of the second columnar check valve body 42, and the top area of ​​the second check valve end cover 421 is larger than the area of ​​the through hole in the middle of the second columnar check valve body 42. A metal spring 422 is provided between the second check valve end cover 421 and the second columnar check valve body 42. When water flows from top to bottom, it impacts the second check valve end cover 421 to move downward, and the metal spring 42 is deformed, and the through hole in the middle of the second columnar check valve body 42 is connected. When water flows back, the impact of the metal spring 42 and the water will drive the second check valve end cover 421 to move upward until the through hole in the middle of the second columnar check valve body 42 is blocked.

[0034] One of the check valve elements 4 includes a third columnar check valve body 43. Inside the third columnar check valve body 43, there are two deformable inclined bosses 431. There is a gap between adjacent inclined bosses 431. When water flows from top to bottom, it will impact the inclined bosses 431, and the gap between the inclined bosses 431 will open, allowing water to flow normally. However, when water flows back from bottom to top, the inclined bosses 431 will deform, and they will squeeze each other, causing the gap to disappear, so that the flowing-back water cannot flow upward.

[0035] One of the check valve elements 4 includes a fourth columnar check valve body 44 and a third check valve end cap 441. The surface of the fourth columnar check valve body 44 is provided with sliding support columns 442. The third check valve end cap 441 is slidably arranged on the sliding support columns 442. The end area of the third check valve end cap 441 is larger than the area of the inner through hole of the fourth columnar check valve body 44. When water flows from top to bottom, it will impact the third check valve end cap 441. The third check valve end cap 441 slides on the sliding support columns 442, and the gap between the third check valve end cap 441 and the through hole in the middle of the fourth columnar check valve body 44 opens, allowing water to flow normally. When water flows back from bottom to top, the water impacts the third check valve end cap 441, causing it to block the through hole in the middle of the fourth columnar check valve body 44, and the water flow cannot continue to flow back upward.

[0036] Working principle and usage method of the present utility model:

[0037] Users can select different filter elements 2 and check valve elements 4 according to the needs for filtration or for preventing backflow, and place them inside the valve body installation channel 15. The height of the filter element 2 determines the height of the check valve element 4. Therefore, there are more choices and better adaptability and versatility during the installation process.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
