[0030] The following is combined with Figure 1-Figure 6 This application is described in further detail.

[0031] The embodiment of the present application discloses a self-cleaning filtering ball valve 100 .

[0032] Reference Figure 1-Figure 3 According to the embodiment of the present application, the self-cleaning filter ball valve 100 comprises: a valve body 1, a valve core 2, a cleaning member 3 and a filter mechanism 4. Along the first direction of the valve body 1, one end of the valve body 1 is provided with a liquid inlet 11, and the other end of the valve body 1 is provided with a liquid outlet 18. The valve body 1 defines an infusion channel 12, and the liquid inlet 11 and the liquid outlet 18 are both connected to the infusion channel 12. The valve core 2 is movably provided on the valve body 1, and the valve core 2 is used to open or close the infusion channel 12. Specifically, the liquid inlet 11 is located at the left end of the valve body 1, and the liquid outlet 18 is located at the right end of the valve body 1. The first direction of the valve body 1 can refer to Figure 2 The left and right direction in .

[0033] In addition, the infusion channel 12 forms a drain hole 13 on the outer peripheral wall of the valve body 1 . The drain hole 13 is configured as a through hole and can be communicated with a drain pipe.

[0034] The cleaning member 3 is disposed at the liquid inlet 11 and is pivotally connected to the valve body 1. Specifically, along the first direction of the valve body 1, the left end of the cleaning member 3 is disposed at the liquid inlet 11 and is pivotally connected to the valve body 1, and the right end of the cleaning member 3 extends into the valve body 1. When the liquid enters the infusion channel 12 through the liquid inlet 11, the liquid drives the cleaning member 3 to rotate around the central axis of the cleaning member 3. The end wall of the cleaning member 3 away from the liquid inlet 11 is provided with bristles. Specifically, the bristles are located on the right end wall of the cleaning member 3. Along the radial direction of the valve body 1, the right end wall of the cleaning member 3 and the bristles are both suitable for being opposite to the drainage hole 13.

[0035] The filter mechanism 4 is arranged in the valve body 1 and is located on the side of the cleaning member 3 away from the liquid inlet 11, that is, the filter mechanism 4 is located on the right side of the cleaning member 3. The filter assembly includes a filter element 41 and a drive assembly 42. The filter element 41 is slidably matched with the valve body 1. The filter element 41 is provided with a filter hole 411. The filter element 41 is used to filter liquid and open or close the sewage hole 13. The filter element 41 is suitable for being driven by the drive assembly 42 or by the liquid in the infusion channel 12, and the filter element 41 slides along the first direction of the valve body 1 when being driven.

[0036] Furthermore, there are multiple filter holes 411 , which are spaced apart along the radial direction of the filter element 41 . The multiple filter holes 411 filter impurities in the liquid at the same time, thereby improving the efficiency of the filter element 41 in filtering the liquid.

[0037] When the filter element 41 is blocked, the driving assembly 42 drives the filter element 41 to move closer to the cleaning element 3, the filter element 41 opens the drainage hole 13 and stops against the bristles. When the filter element 41 is not blocked, the liquid in the infusion channel 12 drives the filter element 41 to move away from the cleaning element 3, and the filter element 41 closes the drainage hole 13.

[0038] Specifically, when liquid enters the infusion channel 12 through the liquid inlet 11, the liquid drives the cleaning member 3 to drive the bristles to rotate around the central axis of the cleaning member 3. After the liquid enters the infusion channel 12, the filter 41 filters the liquid in the infusion channel 12, and the impurities in the liquid are deposited on the end wall of the filter 41 close to the cleaning member 3. When the filter 41 is blocked by impurities, the driving component 42 drives the filter 41 to move close to the cleaning member 3, and the end wall of the filter 41 where impurities are deposited abuts against the bristles, and the filter 41 opens the drain hole 13. The bristles clean the impurities deposited on the filter 41 to separate the impurities from the filter 41. Then the liquid in the infusion channel 12 drives the impurities in the infusion channel 12 to flow out of the valve body 1 through the drain hole 13, thereby achieving the technical effect of the cleaning member 3 automatically cleaning the filter 41.

[0039] After the cleaning member 3 finishes cleaning the filter element 41, the liquid that enters the infusion channel 12 through the liquid inlet 11 flows toward the liquid outlet 18, and in the process of the liquid flowing toward the liquid outlet 18, the liquid drives the filter element 41 to move away from the cleaning member 3, the filter element 41 closes the drain hole 13, and the liquid in the infusion channel 12 flows out of the valve body 1 through the liquid outlet 18.

[0040] In some specific embodiments, the self-cleaning filter ball valve 100 also includes a controller, the drive component 42 is constructed as an electromagnet, a flow detection component is arranged in the valve body 1, the flow detection component is arranged near the liquid outlet 18 of the valve body 1, the flow detection component is used to detect the liquid flow value of the liquid outlet 18 of the valve body 1, the flow detection component and the drive component 42 are both communicatively connected to the controller, and the controller is used to control the drive component 42 to start or stop working according to the detection signal of the flow detection component.

[0041] When the filter element 41 is blocked, the liquid flow rate of the liquid outlet 18 of the valve body 1 decreases, the flow detection element generates a first detection signal, and the controller controls the drive component 42 to start working according to the first detection signal of the flow detection element, and the drive component 42 drives the filter element 41 to move closer to the cleaning element 3. When the filter element 41 is not blocked, the liquid flow value of the liquid outlet 18 of the valve body 1 is equal to the preset liquid flow value, the flow detection element generates a second detection signal, and the controller controls the drive component 42 to stop working according to the second detection signal of the flow detection element, and the liquid flowing in the infusion channel 12 toward the liquid outlet 18 drives the filter element 41 to move away from the cleaning element 3.

[0042] In some specific embodiments, the flow detection element is preferably a turbine flow meter or the like.

[0043] Thus, the cleaning member 3 is driven by liquid to drive the bristles to rotate around the central axis of the cleaning member 3. When the filter 41 is blocked, the driving assembly 42 drives the filter 41 to move close to the cleaning member 3, the filter 41 abuts against the bristles and opens the drainage hole 13, the bristles clean the filter 41, and the liquid in the infusion channel 12 drives the impurities in the infusion channel 12 to flow out of the valve body 1 through the drainage hole 13. Compared with the prior art, workers do not need to frequently clean the filter 41, thereby reducing the number of times workers clean the filter 41, reducing the maintenance cost of the filter ball valve, and thus improving the use experience of the filter ball valve.

[0044] Reference Figure 2 , Figure 3 and Figure 5In some embodiments of the present application, the driving component 42 is located on a side of the filter element 41 away from the cleaning element 3, that is, along the first direction of the valve body 1, the driving component 42 is located on the right side of the filter element 41, the driving component 42 includes a push plate 421 and an elastic member 422, the push plate 421 is slidably matched with the valve body 1, and the push plate 421 moves along the first direction of the valve body 1 when driven, and the push plate 421 is located on a side of the cleaning element 3 away from the liquid inlet 11, that is, the push plate 421 is located on the right side of the filter element 41.

[0045] The push plate 421 is provided with a first communication hole 4211 opposite to the filter hole 411 . The liquid enters the infusion channel 12 through the liquid inlet 11 , and then flows into the liquid outlet 18 through the filter hole 411 and the first communication hole 4211 in sequence.

[0046] Furthermore, the first communication hole 4211 is opposite to the plurality of filtering holes 411 .

[0047] Along the first direction of the valve body 1, the filter element 41 is suitable for being spaced apart from the push plate 421, and a support portion 14 is provided on the inner peripheral wall of the valve body 1. The support portion 14 is located on the side of the push plate 421 away from the filter element 41, and the elastic member 422 is elastically deformably arranged between the push plate 421 and the support portion 14. The elastic member 422 is used to drive the push plate 421 to drive the filter element 41 to move closer to the cleaning member 3.

[0048] Specifically, when the filter element 41 is blocked, the liquid flow on the side of the filter element 41 away from the liquid inlet 11 is reduced, and the liquid pressure value on the side of the filter element 41 away from the liquid inlet 11 is reduced, and the thrust exerted by the liquid between the filter element 41 and the push plate 421 on the push plate 421 in the direction away from the filter element 41 is reduced. When the thrust exerted by the liquid between the filter element 41 and the push plate 421 on the push plate 421 is less than the thrust exerted by the elastic member 422 on the push plate 421 in the direction close to the filter element 41, the elastic member 422 drives the push plate 421 to move close to the filter element 41 to reduce the spacing distance between the push plate 421 and the filter element 41. When the push plate 421 is stopped, the elastic member 422 drives the push plate 421 to drive the filter element 41 to move close to the cleaning member 3, so that the cleaning member 3 stops against the bristles, thereby achieving the technical effect of the drive component 42 driving the filter element 41 to move close to the cleaning member 3.

[0049] When the filter element 41 is not blocked, the liquid flowing in the infusion channel 12 toward the liquid outlet 18 drives the filter element 41 to drive the push plate 421 to move away from the cleaning element 3. When the filter element 41 moves away from the cleaning element 3 to a preset position, the filter element 41 and the valve body 1 limit the fit and stop moving. The liquid flowing in the infusion channel 12 toward the liquid outlet 18 passes through the filter element 41 and drives the push plate 421 to move away from the cleaning element 3, so as to reset the filter element 41.

[0050] It should be noted that the spacing distance between the cleaning element 3 and the filter element 41 and the spacing distance between the push plate 421 and the filter element 41 are both small. In some specific embodiments, the spacing distance between the cleaning element 3 and the filter element 41 and the spacing distance between the push plate 421 and the filter element 41 can both be 5 mm, the length of the bristles can be 3 mm, and the push plate 421 only needs to slightly push the filter element 41 to stop the filter element 41 and the bristles.

[0051] Furthermore, when the filter element 41 is slightly clogged, the elastic element 422 drives the push plate 421 to drive the filter element 41 to move closer to the cleaning element 3, so that the filter element 41 can be cleaned quickly and a large amount of impurities can be prevented from being deposited on the filter element 41.

[0052] In some specific embodiments, the elastic member 422 is preferably a spring or the like.

[0053] Reference Figure 2 , Figure 3 and Figure 5 In some embodiments of the present application, the driving assembly 42 may further include a covering member 423, which is telescopically and deformably connected between the push plate 421 and the support portion 14, and the covering member 423 is sealedly connected to both the push plate 421 and the support portion 14. That is, along the first direction of the valve body 1, one end of the covering member 423 is connected to and cooperated with the end wall of the push plate 421 away from the filter element 41 and is sealed, and the other end of the covering member 423 is connected to and cooperated with the end wall of the support portion 14 close to the filter element 41 and is sealed.

[0054] In addition, the covering member 423 covers the outer side of the elastic member 422, thereby preventing the liquid in the infusion channel 12 from contacting the elastic member 422, avoiding the elastic member 422 from being corroded and rusted due to long-term contact between the elastic member 422 and the liquid in the infusion channel 12, thereby increasing the service life of the elastic member 422 and further increasing the service life of the self-cleaning filter ball valve 100.

[0055] In some specific embodiments, the covering member 423 may be a silicone tube, but the present application is not limited thereto, and the covering member 423 may also be a rubber bellows or the like.

[0056] Reference Figure 2 , Figure 3 and Figure 5In some embodiments of the present application, there are multiple elastic members 422, and the multiple elastic members 422 are spaced apart along the circumferential direction of the valve body 1. By setting multiple elastic members 422, the multiple elastic members 422 jointly drive the push plate 421 to drive the filter element 41 to move close to the cleaning element 3, thereby preventing the push plate 421 from tilting during the process of driving the filter element 41 to move close to the cleaning element 3, resulting in some filter holes 411 of the cleaning element 3 being unable to stop with the bristles, thereby improving the movement stability of the push plate 421, and further improving the working reliability of the self-cleaning filter ball valve 100.

[0057] Furthermore, there are a plurality of covering members 423 , and the covering members 423 are arranged at intervals along the circumferential direction of the valve body 1 , and the covering members 423 and the elastic members 422 are arranged in a one-to-one correspondence.

[0058] Reference Figure 2 and Figure 3 In some embodiments of the present application, the outer wall of the filter element 41 is provided with an avoidance hole 412, and the avoidance hole 412 is constructed as a through hole. The avoidance hole 412 is suitable to be opposite to the sewage hole 13, and the avoidance hole 412 is suitable to be connected between the infusion channel 12 and the sewage hole 13. When the driving component 42 drives the filter element 41 to move close to the cleaning element 3, the avoidance hole 412 is opposite to the sewage hole 13.

[0059] Specifically, when the elastic member 422 drives the push plate 421 to drive the filter element 41 to move closer to the cleaning element 3, the avoidance hole 412 moves closer to the drain hole 13, and the avoidance hole 412 gradually becomes opposite to and connected with the drain hole 13. When the filter element 41 and the bristles stop, the avoidance hole 412 is completely opposite to the drain hole 13, and the liquid in the infusion channel 12 drives the impurities in the infusion channel 12 to flow out of the valve body 1 through the avoidance hole 412 and the drain hole 13 in turn.

[0060] Furthermore, when the filter element 41 is not blocked, the liquid in the infusion channel 12 drives the filter element 41 to move away from the cleaning element 3, and the avoidance hole 412 moves away from the drain hole 13. When the avoidance hole 412 is not opposite to the drain hole 13, the filter element 41 closes the drain hole 13, thereby achieving the technical effect of the filter element 41 opening or closing the drain hole 13.

[0061] Reference Figure 2 and Figure 5In some embodiments of the present application, the inner circumferential wall of the valve body 1 is provided with a guide track 15, and the outer circumferential wall of the filter element 41 is provided with a guide portion 413, and the guide portion 413 and the guide track 15 are guided and cooperated. Through the guiding cooperation between the guide portion 413 and the guide track 15, the filter element 41 can be prevented from deviating from the preset motion trajectory, and the filter element 41 can be prevented from failing to stop with the bristles, thereby improving the movement stability of the filter element 41 and improving the working reliability of the self-cleaning filter ball valve 100.

[0062] Furthermore, the guide portion 413 is also limitedly cooperated with the guide rail 15. Specifically, along the first direction of the valve body 1, when the filter element 41 moves close to the cleaning element 3 and stops with the bristles, the guide portion 413 stops and limits the left end portion of the guide rail 15, thereby preventing the filter element 41 from continuously moving close to the cleaning element 3, and preventing the cleaning element 3 from colliding and rubbing with the filter element 41 to cause damage to the filter element 41, thereby improving the working reliability of the self-cleaning filter ball valve 100.

[0063] When the filter element 41 moves away from the cleaning element 3 to a preset position, the guide portion 413 stops and limits the right end portion of the guide rail 15, thereby preventing the filter element 41 from continuously moving away from the cleaning element 3 and preventing the filter element 41 from being unable to be spaced apart from the push plate 421.

[0064] Furthermore, there are multiple guide rails 15 and multiple guide parts 413, and the multiple guide rails 15 and the multiple guide parts 413 are spaced apart along the circumferential direction of the valve body 1, and the multiple guide rails 15 and the multiple guide parts 413 are arranged one by one, and the multiple guide rails 15 can guide the filter element 41, thereby further improving the movement stability of the filter element 41.

[0065] Reference Figure 2 , Figure 4 and Figure 6 In some embodiments of the present application, the liquid inlet 11 is provided with a pivot portion 111, the pivot portion 111 defines a pivot space 1111, and the end wall of the pivot portion 111 away from the liquid inlet 11 is provided with a second connecting hole 1112, the second connecting hole 1112 is configured as a through hole, the second connecting hole 1112 is connected between the pivot space 1111 and the infusion channel 12, the valve body 1 defines a liquid inlet channel 16, the liquid inlet channel 16 is connected between the pivot space 1111 and the liquid inlet 11, and the liquid located at the liquid inlet 11 flows into the infusion channel 12 through the liquid inlet channel 16, the pivot space 1111 and the second connecting hole 1112 in sequence.

[0066] The end of the cleaning member 3 close to the liquid inlet 11 is arranged in the pivot space 1111 and is pivotally connected to the pivot part 111. The outer peripheral wall of the cleaning member 3 is provided with a plurality of drive blades 31. The plurality of drive blades 31 are arranged at intervals along the circumferential direction of the cleaning member 3 and are all located in the pivot space 1111. Specifically, along the first direction of the valve body 1, the left end of the cleaning member 3 is arranged in the pivot space 1111 and is pivotally connected to the pivot part 111. The plurality of drive blades 31 are all arranged on the outer peripheral wall of the left end of the cleaning member 3.

[0067] Furthermore, there is an angle between the driving blade 31 and the outer peripheral wall of the cleaning member 3 , that is, the driving blade 31 is obliquely arranged on the outer peripheral wall of the cleaning member 3 , and the communication port between the liquid inlet channel 16 and the pivot space 1111 is suitable to be opposite to the side wall of the driving blade 31 .

[0068] Specifically, when the liquid in the liquid inlet channel 16 flows into the pivot space 1111, the liquid contacts the side wall of the driving blade 31, and then the liquid applies a driving force to the driving blade 31, so that the driving blade 31 drives the cleaning member 3 to rotate around the central axis of the cleaning member 3, thereby achieving the technical effect of the liquid driving the cleaning member 3 to rotate around the central axis of the cleaning member 3.

[0069] In some specific embodiments, the communication port between the liquid inlet channel 16 and the pivot space 1111 is located above the plurality of driving blades 31 . In other specific embodiments, the communication port between the liquid inlet channel 16 and the pivot space 1111 is located below the plurality of driving blades 31 .

[0070] Reference Figure 2 , Figure 4 and Figure 6 In some embodiments of the present application, the valve body 1 defines a liquid outlet channel 17, which is connected between the pivot space 1111 and the infusion channel 12. Along the radial direction of the valve body 1, the connecting port between the liquid outlet channel 17 and the infusion channel 12 is opposite to the bristles.

[0071] Specifically, when the filter element 41 and the bristles are stopped, the connecting port between the liquid outlet channel 17 and the infusion channel 12 and the bristles and the drain hole 13 are relative, and the liquid in the pivot space 1111 flows into the infusion channel 12 through the liquid outlet channel 17. The liquid flowing out of the infusion channel 12 drives the impurities in the infusion channel 12 to flow out of the valve body 1 through the drain hole 13, thereby minimizing the amount of impurity accumulation in the valve body 1, and extending the time before the filter element 41 is blocked again, thereby improving the user experience of the self-cleaning filter ball valve 100.

[0072] Furthermore, the liquid flowing out of the liquid infusion channel 12 can also rinse the bristles, thereby minimizing the amount of impurities adhering to the bristles.

[0073] In some specific embodiments, when the connecting port between the liquid inlet channel 16 and the pivot space 1111 is located above the multiple driving blades 31, the connecting port between the liquid outlet channel 17 and the pivot space 1111 can be located below the multiple driving blades 31, that is, the connecting port between the liquid inlet channel 16 and the pivot space 1111 and the connecting port between the liquid outlet channel 17 and the pivot space 1111 are opposite to each other.

[0074] In some specific embodiments, when the communication port between the liquid inlet channel 16 and the pivoting space 1111 is located below the plurality of driving blades 31 , the communication port between the liquid outlet channel 17 and the pivoting space 1111 may be located above the plurality of driving blades 31 .

[0075] Reference Figure 3 , Figure 5 and Figure 6 In some embodiments of the present application, there are multiple second connecting holes 1112, and the multiple second connecting holes 1112 are spaced apart along the circumferential direction of the pivot portion 111. The liquid in the pivot space 1111 flows into the infusion channel 12 through the multiple second connecting holes 1112, thereby increasing the liquid output flow value of the valve body 1.

[0076] Reference Figure 3 , Figure 5 and Figure 6 In some embodiments of the present application, the end wall of the cleaning member 3 on which the bristles are provided is provided with a plurality of flushing holes 32. Specifically, along the first direction of the valve body 1, the right end wall of the cleaning member 3 is provided with a plurality of flushing holes 32. The plurality of flushing holes 32 are spaced apart along the radial direction of the cleaning member 3, and the plurality of flushing holes 32 are all opposite to the filter member 41. The liquid at the liquid inlet 11 flows into the infusion channel 12 through the flushing holes 32.

[0077] Specifically, when the filter element 41 abuts against the bristles, the liquid in the liquid inlet 11 enters the liquid infusion channel 12 through the flushing hole 32 , and then the liquid flushes the filter element 41 , thereby improving the effect of the cleaning element 3 in cleaning the filter element 41 .

[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
