Embodiments of the present invention

[0040] The specific embodiments of the present invention 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 provided on the lower end face of the control cavity 4. A valve core assembly 7 is installed 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. The lower end of the purified water flow channel 9 has an inlet 11 for connecting to the purified water interface 63 of the filter bottle, allowing water to enter the filter element for filtration. The lower end of the inlet flow channel 10 has an inlet 12 for communicating with the filter chamber 61 of the filter bottle, allowing water to directly enter the filter chamber 61. Inside, 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 to the filter bottle outlet 69. The lower end face of the valve body 1 is respectively formed with a clean water channel one 14 and a clean water channel two 15. One end of the clean water channel one 14 is connected to the clean water inlet 13, and the other end of the clean water channel one 14 is connected to the clean water channel two 15 through the control channel 20. The other end of the clean water channel two 15 is connected to the water outlet connector 3.

[0042] The design of the inlet 5 and the inlet 6 allows the valve core assembly 7 to control the opening size of the inlet 5 and the inlet 6 during actual use, thereby adjusting the ratio of all filtered water to partially filtered water. This ensures a stable output water quality regardless of the local water quality or the requirements of the water source.

[0043] After the filter regulating valve is connected to the filter bottle body 60, referring to Figures 4 and 8, the external water source will first enter the valve core assembly 7 through the water inlet connector 2, and then be divided into two paths. One path enters the filter element through the water inlet 5, the clean water channel 9, and the water inlet 11 for filtration. The other path enters the filter chamber 61 directly through the water inlet 6, the water channel 10, and the water inlet 12. The filter chamber 61 is equipped with filter materials to improve the taste. Finally, the water from the two paths converges in the filter chamber 61 and flows out from the water outlet connector 3. Therefore, in actual use, the opening size of the water inlet 5 and the water 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, referring to Figures 6 and 10, the water in the filter chamber 61 enters the purified water inlet 13 through the filter bottle outlet 69 (see Figure 15 for details), and then flows out from the water outlet connector 3 after passing through the purified water channel 14, control channel 20, and purified water channel 2 15 in sequence.

[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 downward. Referring to Figures 10, 11 and 16, the water purification channel 15 is closed at this time, 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 flow 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 inside 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. Both the sealing element 27 and the mounting base 25 are provided with clearance holes 28 for the valve stem 19 to extend out.

[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 along the water passage cavity 35. The valve moves vertically between the first position and the second position. See Figure 8 for details. 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 35.

[0052] As shown in 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, it can still flow out from the outlet connector 3 after passing through the water passage 35. This 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. The lower valve plate 44 and the valve seat 43 are respectively provided with a third water inlet 47 connected to the first water inlet 5 and a fourth water inlet 48 connected to the second water inlet 6. 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] The valve body 1 is fitted with a housing 53 on its outer periphery. A push button 54 is mounted 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. A rotatable adjusting knob 57 is provided at the upper end of the housing 53. The upper end of the adjusting rod 46 extends out of the valve body 1 and is connected to the adjusting knob 57. The adjusting knob 57 has a gear position number 58 engraved on its outer wall. An indicator mark 59 is provided on the upper surface of the housing 53. By cooperating with the gear position number 58 and the indicator mark 59, the gear position after rotating the adjusting knob 27 can be clearly known.

[0056] A filter bottle includes the filter regulating valve described in any one of the above claims, and also includes a filter bottle body 60. A filter cavity 61 is formed within the filter bottle body 60, and a filter element 62 is disposed within the filter cavity 61. A water purification interface 63 is formed at the upper end of the filter bottle body 60. The upper end of the water purification interface 63 is connected to a water inlet 11, and the lower end of the water purification interface 63 is connected to the inlet of the filter element 62. The filter element is located in the cavity between the filter cavity 61 and the filter element 62, and the outlet of the filter element 62 is connected to the filter cavity 61. An annular wall 64 is formed on the outer periphery of the water purification interface 63. A water inlet 65 is formed between the annular wall 64 and the water purification interface 63. The upper end of the water inlet 65 is connected to a water inlet 12, and the lower end of the water inlet 65 has a hole 66 communicating with the filter cavity 61. The annular wall 64... The outer periphery is formed with an annular wall 67, and a water outlet 68 is formed between the annular wall 67 and the annular wall 64. The lower end of the water outlet 68 is provided with a filter bottle outlet 69 that communicates with the filter chamber 61, and the upper end of the water outlet 68 is connected to the purified water inlet 13. The outer periphery of the annular wall 67 is formed with an annular wall 70, and the upper end surface of the annular wall 70 is formed with a protrusion 71 for the push part 41 to abut against, so that the valve stem 39 is kept in the first position.
