DETAILED DESCRIPTION

[0019] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0020] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0021] See also Figures 1 to 3 In one embodiment of the present application, a rotary valve core type pulse valve 10 is provided. The rotary valve core type pulse valve 10 is used for a smart toilet so that the smart toilet can spray pulse water, meet the user's use needs, provide a better sense of pressure and impact, and enhance the user's use experience. The rotary valve core type pulse valve 10 of this embodiment includes a pulse housing 11 and a pulse valve core 12.

[0022] The pulse housing 11 has an opening at one end and a receiving chamber 111 therein. The pulse housing 11 is provided with a pulse inlet 112 and a pulse outlet 113, both of which are connected to the receiving chamber 111 and are used to connect to the pipeline of the smart toilet.

[0023] The pulse valve core 12 is arranged in the accommodating chamber 111 of the pulse housing 11, and the pulse valve core 12 includes a core body 121 and a pair of stoppers arranged around the core body 121. The stoppers protrude from the surface of the core body 121, and a gap is provided between the two stoppers. The outer wall of the stopper abuts against the inner wall of the pulse housing 11, and the portion of the core body 121 located between the two stoppers is opposite to the pulse inlet 112 and the pulse outlet 113, and forms a water flow channel 13 with the pulse housing 11.

[0024] In this embodiment, the pulse valve core 12 can rotate relative to the pulse housing 11, so that the stopper switches between the non-stop state and the stopper state, so that the flow area of ​​the water flow channel 13 is periodically increased or decreased. When the stopper is in the stopper state, the stopper partially blocks the pulse inlet 112 and the pulse outlet 113, and the pulse inlet 112 and the pulse outlet 113 are in a semi-open state, so that the flow area of ​​the water flow channel 13 is reduced. When the stopper is in the non-stopper state, the pulse inlet 112 and the pulse outlet 113 are in a fully open state, so that the flow area of ​​the water flow channel 13 is increased.

[0025] Furthermore, the pulse housing 11 of the present embodiment includes a housing body 114 and an assembly portion 115 disposed on the edge of the housing body 114. The housing body 114 is cylindrical in shape as a whole, one end of which is provided with an opening, and an accommodating cavity 111 is provided inside. The pulse inlet 112 and the pulse outlet 113 are both provided on the outer wall of the housing body 114, and the pulse inlet 112 and the pulse outlet 113 are connected to the accommodating cavity 111.

[0026] In this embodiment, the pulse inlet 112 and the pulse outlet 113 are arranged opposite to each other, and the cross section of the pulse inlet 112 and the cross section of the pulse outlet 113 are parallel, that is, in the cross-sectional direction of the shell body, the pulse inlet 112 and the pulse outlet 113 are staggered. The pulse housing 11 of this embodiment also includes an inlet connector 1121 and an outlet connector 1131, and both the inlet connector 1121 and the outlet connector 1131 are tubular structures with openings at both ends and hollow inside.

[0027] The inlet connector 1121 is disposed at the pulse inlet 112 and communicates with the pulse inlet 112, thereby communicating with the accommodating chamber 111 inside the housing body 114. The outlet connector 1131 is disposed at the pulse outlet 113 and communicates with the pulse outlet 113, thereby communicating with the accommodating chamber 111 inside the housing body 114. Both the inlet connector 1121 and the outlet connector 1131 are used to communicate with the pipeline of the smart toilet.

[0028] The assembly part 115 is arranged at the edge of the opening of the shell body 114. In this embodiment, there are four assembly parts 115, but not limited to four. The four assembly parts 115 are arranged at intervals at the edge of the shell body 114. The outer contour of the assembly part 115 is semicircular, and each assembly part 115 is provided with a through hole.

[0029] Furthermore, the pulse valve core 12 is disposed in the accommodating cavity 111 of the pulse housing 11. The pulse valve core 12 of this embodiment includes a core body 121 and a pair of stoppers disposed on the core body 121, the two stoppers being a first stopper 122 and a second stopper 123 respectively.

[0030] In this embodiment, the core body 121 is a cylindrical structure, and the two ends of the core body 121 are respectively an inner end 1211 and an outer end 1212. The inner end 1211 extends into the accommodating cavity 111 of the pulse housing 11 and abuts against the bottom wall of the pulse housing 11.

[0031] The outer end 1212 of the core body 121 protrudes from the opening of the shell body 114. A mating portion 1213 is provided on the outer end 1212 of the core body 121 of this embodiment. The mating portion 1213 is an installation port for installing a driving device to drive the pulse valve core 12 to rotate relative to the pulse shell 11.

[0032] The first stopper 122 is disposed at the inner end 1211 of the core body 121, and the inner end 1211 of the core body 121 slightly exceeds the outer surface of the first stopper 122. The second stopper 123 is disposed on the side of the first stopper 122 away from the inner end 1211, and there is a gap between the second stopper 123 and the end surface of the outer end 1212 of the core body 121.

[0033] The first stopper 122 and the second stopper 123 of this embodiment each include a fixing portion 124 and three stopper portions 125 arranged at the edge of the fixing portion 124. The fixing portion 124 is arranged around the outside of the core body 121, and the three stopper portions 125 are evenly and spaced apart at the end edge of the fixing portion 124, and the interval between two adjacent stopper portions 125 forms a vacant portion 126.

[0034] It is understandable that, in addition to the three stopping portions 125 shown in this embodiment, the number of the stopping portions 125 can also be one, two, four, six, etc., and can be set accordingly according to size and requirements, and no excessive restrictions are made here.

[0035] In the core body 121 of the present embodiment, the end of the fixing portion 124 of the first stopper 122 provided with the stopper 125 and the end of the fixing portion 124 of the second stopper 123 provided with the stopper 125 are arranged opposite to each other. The stopper 125 of the first stopper 122 corresponds to the vacant portion 126 of the second stopper 123, and the vacant portion 126 of the first stopper 122 corresponds to the stopper 125 of the second stopper 123.

[0036] The pulse valve core 12 is inserted into the accommodating cavity 111 of the pulse housing 11 , the inner end 1211 of the core body 121 abuts against the bottom wall of the pulse housing 11 , and the outer peripheral side walls of the first stopper 122 and the second stopper 123 abut against the inner wall of the pulse housing 11 .

[0037] In the cross-sectional direction of the rotary valve core pulse valve 10, the first stopper 122 corresponds to the pulse inlet 112, and the second stopper 123 corresponds to the pulse outlet 113. A water flow channel 13 is formed between the area between the first stopper 122 and the second stopper 123 on the core body 121 and the pulse housing 11. Flushing water flows into the water flow channel 13 from the pulse inlet 112, and then flows out from the water flow channel 13 through the pulse outlet 113.

[0038] When the pulse valve core 12 rotates relative to the pulse housing 11 , the stopper 125 and the vacant portion 126 of the first stopper 122 correspond to the pulse inlet 112 alternately, and the stopper 125 and the vacant portion 126 of the second stopper 123 correspond to the pulse outlet 113 alternately.

[0039] Specifically, when the stopping portion 125 of the first stopper 122 partially blocks the pulse inlet 112, the stopping portion 125 of the second stopper 123 partially blocks the pulse outlet 113 simultaneously. At this time, the pulse inlet 112 and the pulse outlet 113 are both in a semi-open state, and the flow area of ​​the water flow channel 13 is reduced, so that the pressure of the flushing water flow out of the rotary valve core type pulse valve 10 is increased.

[0040] When the vacant portion 126 of the first block 122 corresponds to the pulse inlet 112, the vacant portion 126 of the second block 123 corresponds to the pulse outlet 113 at the same time. At this time, the pulse inlet 112 and the pulse outlet 113 are both fully open, and the flow area of ​​the water channel 13 is increased to reduce the pressure of the flushing water flow out of the rotary valve core type pulse valve 10.

[0041] During the rotation of the pulse valve core 12 relative to the pulse housing 11, the pulse inlet 112 and the pulse outlet 113 are alternately in a semi-open state and a fully open state, so that the flow area of ​​the water flow channel 13 is periodically reduced or increased, and the pressure of the flushing water flow out of the rotary valve core type pulse valve 10 is alternately increased or decreased, so that the user can obtain a gradual sense of pressure and impact when using it, so as to achieve the comfort of massage and enhance the user's experience.

[0042] Furthermore, the pulse valve core 12 of this embodiment further includes a mounting portion 127 . The mounting portion 127 is disposed around the core body 121 and is disposed close to the outer end 1212 of the core body 121 .

[0043] In this embodiment, the outer diameter of the mounting portion 127 is smaller than the outer diameter of the stopper. When the pulse valve core 12 is inserted into the pulse housing 11, there is a gap between the outer peripheral side of the mounting portion 127 and the inner wall of the pulse housing 11. There is a gap between the mounting portion 127 and the end surface of the second stopper 123, and the gap between the two constitutes the first mounting position 128. There is also a gap between the mounting portion 127 and the end surface of the outer end 1212 of the core body 121, and the gap between the two constitutes the second mounting position 129.

[0044] The rotary valve core type pulse valve 10 of this embodiment further includes an end cover 14, which includes a cover body 141 and a connecting portion 142 arranged at the outer peripheral edge of the cover body 141. The outer contour of the cover body 141 is circular. A mounting hole 1411 is opened in the middle of the cover body 141, and the cover body 141 is sleeved on the outer end 1212 of the core body 121 through the mounting hole 1411, and is located at the second mounting position 129 of the core body 121.

[0045] The number of the connecting parts 142 on the end cover 14 is consistent with the number of the assembly parts 115 on the pulse housing 11, and the positions of the connecting parts 142 and the assembly parts 115 correspond. The connecting part 142 is semicircular and similar to the assembly part 115, and the connecting part 142 and the assembly part 115 are provided with through holes correspondingly, and the connecting parts are passed through the through holes so that the end cover 14 is fixed on the pulse housing 11.

[0046] The connecting piece may be a bolt, a pin or other structure, which is not limited here, as long as it can ensure that the end cover 14 and the pulse housing 11 are firmly connected.

[0047] By setting the end cover 14, the pulse valve core 12 inside the pulse housing 11 can be protected, and at the same time, the relative rotation of the pulse valve core 12 is not interfered with, so as to ensure the stability of the overall structure of the rotary valve core type pulse valve 10 and ensure that the rotary valve core type pulse valve 10 can stably regulate the water flow pressure.

[0048] In addition, the rotary valve core type pulse valve 10 of this embodiment further includes a first sealing ring 15 and a second sealing ring 16. The first sealing ring 15 is sleeved on the mounting portion 127, and the outer periphery of the first sealing ring 15 abuts against the inner wall of the pulse housing 11. The second sealing ring 16 is sleeved on the core body 121 and is arranged at the first mounting position 128. The outer periphery of the second sealing ring 16 abuts against the inside of the pulse housing 11.

[0049] The first sealing ring 15 and the second sealing ring 16 can ensure the sealing inside the pulse housing 11, prevent water from flowing out of the end cover 14, ensure that the flushing water only flows through the water channel 13, and ensure that the rotary valve core pulse valve 10 controls the water pressure.

[0050] For the rotary valve core type pulse valve for smart toilets of this embodiment, during the rotation of the pulse valve core relative to the pulse housing, the block of the pulse valve core switches between a blocking state and a non-blocking state, and the pulse inlet and the pulse outlet are alternately in a semi-open state and a fully open state, so that the flow area of ​​the water flow channel is periodically reduced or increased, so that the pressure of the flushing water flowing out of the rotary valve core type pulse valve is alternately increased or decreased, so that the user can obtain a gradual sense of pressure and impact when using it, so as to achieve the comfort of massage and enhance the user's experience.

[0051] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
