[0023] The pulse housing 21 has an accommodating space 211 therein. The pulse housing 21 has a water inlet 212 and a water outlet 213 connected to the accommodating space 211. The water inlet 212 and the water outlet 213 are both used to connect to the pipeline of the smart toilet. The water inlet 212 forms a water flow channel 24 through the accommodating space 211 to the water outlet 213.

[0024] The diverter disc 22 is fixed in the accommodation space 211 of the pulse housing 21, and the peripheral side of the diverter disc 22 abuts against the inner wall of the pulse housing 21. The diverter disc 22 is arranged toward the water inlet 212, and a plurality of diverter ports 221 are provided at intervals on the diverter disc 22. The pulse valve core 23 is arranged in the accommodation space 211 of the pulse housing 21, and the pulse valve core 23 includes a core body 231 and a rotating disc 232 arranged around the core body 231. The rotating disc 232 includes a disc body 2321 and a water outlet 2322 provided on the disc body 2321, and the end face of the disc body 2321 abuts against the surface of the diverter disc 22.

[0025] In this embodiment, the pulse valve core 23 can rotate relative to the pulse housing 21 so that the disc body 2321 and the water outlet 2322 alternately correspond to part of the diversion ports 221 on the diversion disc 22, so that part of the diversion ports 221 are in a blocked state or an open state, thereby causing the flow area of ​​the water flow channel 24 to periodically decrease or increase.

[0026] Furthermore, the pulse housing 21 includes a housing body 214 and an outer cover 215. The housing body 214 includes a transition portion 2141 and a housing portion 2142 connected to the transition portion 2141. The housing portion 2142 is a cylindrical structure with openings at both ends and a hollow interior. The water outlet 213 is provided on the side wall of the housing portion 2142.

[0027] The transition part 2141 is a conical structure with two openings at both ends, and the two openings at the transition part 2141 are respectively a large port and a small port. The large port is arranged at the opening at one end of the shell part 2142, and the small port constitutes the water inlet 212. The internal space of the transition part 2141 and the internal space of the shell part 2142 constitute the accommodating space 211 of the pulse shell 21.

[0028] The outer cover 215 is disposed at another end of the housing portion 2142 to block the housing body 214. The housing body 214 of this embodiment further includes an assembly portion 2143, which is disposed at the edge of the end of the housing portion 2142. The assembly portion 2143 is a columnar structure, and four of the assembly portions 2143 are arranged at intervals along the circumference of the housing portion 2142.

[0029] It is understandable that the number of the assembly parts 2143 may be three, five, six, etc. The number of the assembly parts 2143 is not limited here and may be determined according to the size of the pulse housing 21 and assembly requirements.

[0030] The assembly portion 2143 is provided with an assembly hole 2144, and the extension direction of the assembly hole 2144 is consistent with the length direction of the pulse housing 21. The outer cover 215 is provided with a fixing hole 2151 at a position corresponding to the assembly hole 2144. The connecting piece is inserted into the assembly hole 2144 and the fixing hole 2151 to connect and fix the outer cover 215 to the housing body 214.

[0031] The connecting member of this embodiment can be a bolt, a pin, etc., and no further limitation is given here, as long as the shell body 214 and the outer cover 215 can be firmly connected.

[0032] In this embodiment, an opening 2152 is formed in the middle of the outer cover 215. The pulse valve core 23 is inserted into the pulse housing 21, and an end of the pulse valve core 23 is inserted into the opening 2152 to be connected to an external driving device.

[0033] In addition, the shell body 214 further includes a transition portion 2145. The transition portion 2145 is disposed at the edge of the end of the shell portion 2142, and the transition portion 2145 is spaced apart from the assembly portion 2143. In this embodiment, two transition portions 2145 are provided, and one transition portion 2145 is provided between two adjacent assembly portions 2143.

[0034] The adapter portion 2145 is provided with an adapter hole 2146, and the extension direction of the adapter hole 2146 is consistent with the length direction of the pulse housing 21. The adapter hole 2146 is used to connect with other related components of the smart toilet to achieve the connection of other functional components of the rotary pulse valve 20. The outer cover 215 is provided with an avoidance opening 2153 at a position corresponding to the adapter portion 2145, and the avoidance opening 2153 is an arc-shaped notch.

[0035] The pulse housing 21 of the present embodiment further includes a first joint 216 and a second joint 217 . The first joint 216 and the second joint 217 are both tubular structures with openings at both ends and a hollow interior.

[0036] The first connector 216 is disposed at the water inlet 212 and communicates with the water inlet 212, thereby communicating with the accommodation space 211 inside the pulse housing 21. The second connector 217 is disposed at the water outlet 213 and communicates with the water outlet 213, thereby communicating with the accommodation space 211 inside the pulse housing 21. Both the first connector 216 and the second connector 217 are used to communicate with the pipeline of the smart toilet.

[0037] Further, the diverter plate 22 is a circular structure, which is arranged at the connection between the transition portion 2141 and the housing portion 2142 of the pulse housing 21. The inner diameter of the housing portion 2142 of this embodiment is larger than the inner diameter at the large port of the transition portion 2141, so as to form a step-like structure at the connection between the transition portion 2141 and the housing portion 2142.

[0038] The outer peripheral edge of the diverter plate 22 is in a stepped structure, and the outer diameter of the diverter plate 22 is adapted to the inner diameter of the housing portion 2142, so that the diverter plate 22 is stably clamped on the stepped structure formed at the connection between the transition portion 2141 and the housing portion 2142. The diverter plate 22 is provided with a diverter port 221, and the flushing water flows into the interior of the pulse housing 21 from the water inlet 212, and flows to the water outlet 213 through the diverter port 221 on the diverter plate 22.

[0039] In this embodiment, there are four diversion openings 221 on the diversion plate 22, and the four diversion openings 221 include two main openings 2211 and two secondary openings 2212. The two main openings 2211 are on the same circumference, which is the first circumference. The two secondary openings 2212 are on the same circumference, which is the second circumference.

[0040] In this embodiment, the first circle is concentric with the second circle, and the center of the first circle and the center of the second circle are both the center of the diverter plate 22. The diameter of the first circle is greater than the diameter of the second circle, that is, the two main flow ports 2211 are arranged outside the two secondary flow ports 2212.

[0041] In addition, the diverter disc 22 of this embodiment is provided with a receiving groove 222 . The receiving groove 222 is disposed on the surface of the diverter disc 22 facing the pulse valve core 23 , and the receiving groove 222 is located at the center of the diverter disc 22 .

[0042] Furthermore, the pulse valve core 23 is disposed in the accommodating space 211 of the pulse housing 21. The pulse valve core 23 of this embodiment includes a core body 231 and a rotating disk 232 disposed on the core body 231.

[0043] In this embodiment, the core body 231 is a cylindrical structure. The two ends of the core body 231 are respectively an inner end 2311 and an outer end 2312. The inner end 2311 of the core body 231 extends into the accommodating space 211 of the pulse housing 21. The inner end 2311 is clamped in the accommodating groove 222 of the diverter disk 22, so that the surface of the rotating disk 232 abuts against the surface of the diverter disk 22.

[0044] The outer end 2312 of the core body 231 extends out of the opening 2152 of the outer cover 215, and a driving part 2313 is provided on the end surface of the outer end 2312. The driving part 2313 is a mounting port for connecting with a driving device so that the driving device drives the pulse valve core 23 to rotate relative to the pulse housing 21.

[0045] The turntable 232 is disposed at the inner end 2311 of the core body 231, and the turntable 232 is annularly disposed on the core body 231. There is a gap between the outer surface of the turntable 232 and the inner end 2311 of the core body 231, and the inner end 2311 of the core body 231 is clamped in the receiving groove 222 of the diverter plate 22, so that the surface of the turntable 232 abuts against the surface of the diverter plate 22.

[0046] The rotating disk 232 of this embodiment is arranged concentrically with the second circumference where the secondary flow port 2212 is located. The edge of the rotating disk 232 is provided with a water outlet 2322, and the water outlet 2322 is provided with two arc-shaped notches. The pulse valve core 23 rotates relative to the pulse housing 21, and the water outlet 2322 and the disk body 2321 on the rotating disk 232 correspond to the secondary flow port 2212 alternately. The main flow port 2211 is located on the outside of the rotating disk 232, that is, during the rotation of the pulse valve core 23, the main flow port 2211 always remains in an open state.

[0047] Specifically, when the disc body 2321 on the rotating disc 232 corresponds to the secondary flow port 2212, the disc body 2321 blocks the secondary flow port 2212, and the flushing water flow cannot pass through the secondary flow port 2212. At this time, the flushing water flow entering from the water inlet 212 can only flow to the water outlet 213 through the main flow port 2211 in an open state, so that the flow area of ​​the water flow channel 24 is reduced, thereby increasing the pressure of the flushing water flow flowing out of the rotating disc pulse valve 20.

[0048] When the water outlet 2322 on the rotary disk 232 corresponds to the secondary outlet 2212, the secondary outlet 2212 is in an open state. At this time, the flushing water entering from the water inlet 212 flows from the main outlet 2211 and the secondary outlet 2212 to the water outlet 213, so that the flow area of ​​the water flow channel 24 is increased, thereby reducing the pressure of the flushing water of the rotary disk pulse valve 20.

[0049] During the rotation of the pulse valve core 23 relative to the pulse housing 21, the disk body 2321 and the water outlet 2322 alternately correspond to the diverter port 221 on the upper part of the diverter disk 22, so that the diverter port 221 on the upper part of the diverter disk 22 is alternately in a blocked state or an open state. Combined with the remaining diverter ports 221 in the open state on the diverter disk 22, the flow area of ​​the water flow channel 24 is periodically reduced or increased, so that the pressure of the flushing water flowing out of the rotary disk pulse valve 20 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.

[0050] In addition, the pulse valve core 23 of this embodiment further includes a mounting body 233. The mounting body 233 is arranged around the core body 231 and is disposed on one side of the rotating disk 232 close to the outer end 2312 of the core body 231, with a gap between the mounting body 233 and the rotating disk 232.

[0051] When the outer cover 215 is fixed on the pulse housing 21 , the end of the outer cover 215 abuts against the mounting body 233 to ensure the stability between the outer cover 215 and the pulse housing 21 .

[0052] By setting the outer cover 215, the pulse valve core 23 inside the pulse housing 21 can be protected, and at the same time, the relative rotation of the pulse valve core 23 is not interfered with, so as to ensure the stability of the overall structure of the rotary disk pulse valve 20 and ensure that the rotary disk pulse valve 20 can stably control the water flow pressure.

[0053] For the turntable pulse valve used in the smart toilet of this embodiment, during the rotation of the pulse valve core relative to the pulse housing, the disk body and the water outlet alternately correspond to the diverter ports on the upper part of the diverter disk, so that the diverter ports on the upper part of the diverter disk are alternately in a blocked state or an open state. Combined with the remaining diverter ports on the diverter disk that are in an open state, 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 turntable 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.

[0054] 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.
