The two main flow ports 2211 are on the same circumference, which is the first circumference. The two secondary flow ports 2212 are on the same circumference, which is the second circumference.

In this embodiment, the first circumference and the second circumference are concentrically arranged, and the center of the first circumference and the center of the second circumference are both the center of diverter tray 22. The diameter of the first circumference is larger than the diameter of the second circumference, i.e. the two main flow openings 2211 are arranged outside the two secondary flow openings 2212.

In addition, the diverter tray 22 of the present embodiment is provided with a receiving groove 222. A receiving groove 222 is provided on a surface of diverter tray 22 facing pulse valve element 23, and this receiving groove 222 is located at the center of diverter tray 22.

Further, the pulse valve core 23 is inserted into the accommodating space 211 of the pulse housing 21. The pulse spool 23 of the present embodiment includes a spool main body 231 and a dial 232 provided on the spool main body 231.

In the present embodiment, the core main body 231 has a cylindrical structure. The core body 231 has inner and outer ends 2311 and 2312 at opposite ends thereof, respectively. The inner end 2311 of the core main body 231 extends into the accommodating space 211 of the pulse housing 21. Inner end 2311 is snap-fit into receiving groove 222 of diverter tray 22 such that the surface of turntable 232 abuts the surface of diverter tray 22.

The outer end 2312 of the core body 231 extends through the opening 2152 in the cover 215, and the end face of the outer end 2312 is provided with a drive 2313. The driving portion 2313 is a mounting opening 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.

The outer surface of the rotary disc 232 is spaced from the inner end 2311 of the core main body 231, and the inner end 2311 of the core main body 231 is clamped in the containing groove 222 of the diverter tray 22, so that the surface of the rotary disc 232 is abutted against the surface of the diverter tray 22.

The turntable 232 of this embodiment is concentrically disposed with the second circumference where the secondary flow port 2212 is located. The edge of carousel 232 is equipped with water mouthful 2322, should cross water mouthful 2322 and be equipped with two, and be the arc breach. The pulse valve core 23 rotates relative to the pulse housing 21, and the water passing port 2322 and the disk main body 2321 on the rotary disk 232 alternately correspond to the secondary flow port 2212. The main flow port 2211 is located outside the rotary disc 232, that is, the main flow port 2211 is always kept in an open state during the rotation of the pulse valve core 23.

Specifically, when the disk main body 2321 of the turntable 232 corresponds to the sub-flow port 2212, the disk main body 2321 blocks the sub-flow port 2212, and the flushing water flow cannot pass through the sub-flow port 2212. At this time, the flushing water flow entering from the water inlet 212 can flow to the water outlet 213 only through the main flow port 2211 in the open state, so that the flow area of the water flow passage 24 is reduced, and the pressure of the flushing water flow flowing out of the rotary disk type pulse valve 20 is increased.

When the water passing port 2322 of the rotary disk 232 corresponds to the secondary flow port 2212, the secondary flow port 2212 is opened. At this time, the flow of the flushing water introduced from the water inlet 212 flows from the main flow port 2211 and the sub flow port 2212 to the water outlet 213, and the flow area of the water flow passage 24 is increased, thereby reducing the pressure of the flushing water flow of the rotary disk type pulse valve 20.

In the process that the pulse valve core 23 rotates relative to the pulse housing 21, the disk main body 2321 and the water through-hole 2322 alternately correspond to the diversion port 221 on the upper portion of the diversion disk 22, so that the diversion port 221 on the upper portion of the diversion disk 22 alternately presents a blocked state or an open state, and in combination with the diversion port 221 remaining on the diversion disk 22 presenting an open state, the flow area of the water flow channel 24 periodically decreases or increases, so that the pressure of the flushing water flow flowing out of the rotary disk type pulse valve 20 alternately increases or decreases, and thus a user obtains gradually changing pressure and impact when using, so as to achieve the comfort of massage, and improve the use experience of the user.

In addition, the pulse valve body 23 of the present embodiment further includes a mounting body 233. The mounting body 233 is annularly provided on the core main body 231 and is provided on a side of the turntable 232 near the outer end 2312 of the core main body 231, with a space between the mounting body 233 and the turntable 232.

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

Through setting up enclosing cover 215, can protect the inside pulse case 23 of pulse casing 21, do not interfere the relative rotation of pulse case 23 simultaneously to ensure carousel formula pulse valve 20 overall structure's stability, guarantee carousel formula pulse valve 20 and regulate and control water pressure steadily.

For the rotating disc type pulse valve for the intelligent closestool of the embodiment, in the process that the pulse valve core rotates relative to the pulse shell, the disc main body and the water passing port alternately correspond to the diversion port on the upper portion of the diversion disc, so that the diversion port on the upper portion of the diversion disc alternately presents a blocking state or an opening state, and the diversion port remaining on the diversion disc presenting the opening state is combined, so that the flow area of the water flow channel periodically reduces or increases, the pressure of the water flow for flushing flowing out of the rotating disc type pulse valve alternately increases or reduces, and therefore a user obtains gradually changed pressure feeling and impact feeling when using the rotating disc type pulse valve, the comfort level of massage is achieved, and the use experience of the user is improved.

While the present invention has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
