Detailed Implementation

[0040] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0041] A filter regulating valve includes a valve body 1, with an inlet connector 2 and an outlet connector 3 connected to its two ends. A control cavity 4, communicating with the inlet connector 2, is formed inside the valve body 1. An inlet 5 and an outlet 6 are respectively opened on the lower end face of the control cavity 4. A valve core assembly 7 is disposed inside the control cavity 4 to control the opening size of the inlet 5 and the outlet 6. A valve bottom cover 8 is installed on the lower end face of the valve body 1. A purified water flow channel 9 communicating with the inlet 5 and an inlet flow channel 10 communicating with the outlet 6 are respectively formed inside the valve bottom cover 8. A purified water interface 6 for connecting to a filter bottle is opened at the lower end of the purified water flow channel 9. The water inlet 11 connected to the filter element enters the filter for filtration. The lower end of the water inlet channel 10 is provided with a second water inlet 12 for communicating with the filter chamber 61 of the filter bottle, which directly enters the filter chamber 61 without passing through the filter element. The lower end face of the valve bottom cover 8 is provided with a clean water inlet 13 for connecting with the filter bottle outlet 69. The lower end face of the valve body 1 is respectively formed with a first clean water channel 14 and a second clean water channel 15. One end of the first clean water channel 14 is connected to the clean water inlet 13, and the other end of the first clean water channel 14 is connected to the second clean water channel 15 through the control channel 20. The other end of the second clean water channel 15 is connected to the water outlet connector 3.

[0042] This utility model, through the design of inlet 5 and inlet 6, allows the valve core assembly 7 to control the opening size of inlet 5 and inlet 6 during actual use, thereby adjusting the ratio of all filtered water to partially filtered water. Depending on the local water quality or the requirements of the water source, a stable output water quality can be achieved.

[0043] When the filter regulating valve is connected to the filter bottle body 60, combined with Figure 4 and Figure 8 First, external water will enter the valve core assembly 7 through the inlet connector 2, and then be divided into two paths. One path enters the filter element through the inlet 5, the clean water channel 9, and the inlet 11 for filtration. The other path enters the filter chamber 61 directly through the inlet 6, the inlet channel 10, and the inlet 12. The filter chamber 61 is equipped with filter material to improve the taste. Finally, the water from the two paths converges in the filter chamber 61 and flows out from the outlet connector 3. Therefore, in actual use, the opening size of the inlet 5 and the inlet 6 can be adjusted by the valve core assembly to adjust the ratio of all filtered water to partially filtered water.

[0044] When water is discharged, combined with Figure 6 , Figure 10 Water in filter chamber 61 enters purified water inlet 13 through filter bottle outlet 69. (See details...) Figure 15 Then, after passing through the first water purification channel 14, the control channel 20, and the second water purification channel 15 in sequence, it flows out from the outlet connector 3.

[0045] A flushing water outlet pipe 16 is installed at one end of the valve body 1, and a flushing water outlet 17 is opened at one end of the control channel 20. A flushing flow channel 18 is formed between the valve body 1 and the valve bottom cover 8, and the flushing water outlet pipe 16 is connected to the flushing water outlet 17 through the flushing flow channel 18.

[0046] A valve stem 19 is movably disposed within the control channel 20. One end of the valve stem 19 abuts against the valve body 1 with a return spring 21, and the other end of the valve stem 19 extends out of the valve body 1 and is provided with a pushing part 22. A sealing plug 23 is provided on the outer periphery of the valve stem 19. The valve stem 19 moves laterally between a first position and a second position along the control channel 20. When the valve stem 19 is in the first position, the flushing outlet 17 is closed, and the clean water channel 14 is connected to the clean water channel 25 through the control channel 20. At this time, clean water can flow out normally through the water outlet connector 3. When the valve stem 19 is in the second position, the clean water channel 25 is closed, and the clean water channel 14 is connected to the flushing outlet 17 through the control channel 20. At this time, the water cannot flow out through the water outlet connector, but flows out through the flushing outlet pipe.

[0047] When the valve body and filter element need to be flushed, the valve stem 10 can be moved to the second position by pushing the push button 54 downwards. Figure 10 , Figure 11 , Figure 16 At this time, the water purification channel 2 15 is closed, and the water will not flow out from the outlet connector. The water can only enter the flushing outlet 17 through the control channel 20, and then flow out from the flushing outlet pipe 16 through the flushing channel 18.

[0048] This technical solution, through the design of the water circuit structure, allows for easy switching between the flushing water circuit and the purification water circuit during actual operation by operating the push button 52, making it convenient and simple to use.

[0049] A sealing ring 24 is provided on the outer periphery of the sealing plug 23. A mounting base 25 is provided in the control channel 20. A water passage hole 26 is opened on the side wall of the mounting base 25. A sealing element 27 is installed at the other end of the control channel 20. An avoidance hole 28 for the valve stem 19 to extend is opened in the sealing element 27 and the mounting base 25 respectively.

[0050] One end of the water inlet connector 2 and the water outlet connector 3 is provided with an external connector 29. The other end of the water inlet connector 2 and the water outlet connector 3 are respectively formed with a connecting connector 1 30 and a connecting connector 2 31. The upper end of the valve body 1 is respectively formed with a connecting interface 1 32 that communicates with the control cavity 4. The lower end of the valve body 1 is respectively formed with a connecting interface 2 33 that communicates with the control cavity 4 and a connecting interface 34 that communicates with the water purification channel 2 15. The connecting connector 1 30 is connected to the connecting interface 1 32. The connecting connector 2 31 of the water inlet connector 2 is connected to the connecting interface 2 33. The connecting connector 2 31 of the water outlet connector 3 is connected to the connecting interface 34.

[0051] The inlet connector 2 and outlet connector 3 each have a water passage cavity 35 formed inside. The water passage cavity 35 is located between the outer connector 29 and the connecting connector. One side of the water passage cavity 35 has an inlet / outlet port 36 for communicating with the outer connector 29. The other side of the water passage cavity 35 has a through hole 37 and a through hole 38. The through hole 37 communicates with the first connecting connector 30, and the through hole 38 communicates with the second connecting connector 31. A valve stem 39 is movably mounted inside the water passage cavity 35. One end of the valve stem 39 abuts against the water passage cavity 35 with a return spring 40. The other end of the valve stem 39 extends out of the connector and is provided with a pushing part 41. A sealing plug 42 is provided on the outer periphery of the valve stem 39. The valve stem 39 moves vertically between the first and second positions along the water passage cavity 35. See details below. Figure 8 When the valve stem 39 is in the first position, the through hole 37 is closed, and the inlet and outlet 36 are connected to the through hole 38 through the water passage cavity 35.

[0052] See details Figure 9 When the filter bottle is removed, the valve stem 39 will automatically move to the second position. At this time, the through hole 38 is closed, and the inlet and outlet 36 are connected to the through hole 37 through the water passage 35. Although the water will not be filtered by the filter element, the water can still flow out from the outlet connector 3 after passing through the water passage 35, which can effectively prevent the subsequent equipment from being damaged due to prolonged dry burning.

[0053] The valve core assembly 7 includes a valve seat 43, a lower valve plate 44, an upper valve plate 45, and an adjusting rod 46 for driving the upper valve plate 45 to rotate.

An adjusting notch 49 is provided on one side of the upper valve plate 45 to control the opening size of the third water inlet 47 and the fourth water inlet 48.

[0054] A partition sleeve 50 is provided between the outer periphery of the adjusting rod 46 and the valve body 1. The partition sleeve 50 divides the control cavity 4 into upper and lower cavities. A straight annular groove 51 is formed on the outer periphery of the upper end of the partition sleeve 50, thereby connecting the cavity between the two connecting joints 30. A through hole 52 connected to the water inlet is provided on the lower side wall of the partition sleeve 50, thereby allowing water to enter the valve core assembly 7.

[0055] A housing 53 is installed on the outer periphery of the valve body 1. A push button 54 is installed on the side wall of the housing 53. The inner side wall of the push button 54 is formed with a push part 55 for pushing the valve stem 19 to move. The valve core assembly 7 includes an adjusting rod 46 for controlling its rotation.
