[0029] Referring to Figure 1 , the present patent embodiment provides a toilet 100 with a pre-wetting mechanism, comprising a seat body 10 and a cover body 20, the cover body 20 being rotatably connected to the seat body 10.
[0030] Referring to Figure 2 and Figure 4 , the seat body 10 has a seating surface 101 and a sewage surface 102. Specifically, the seating surface 101 is arranged on the upper surface of the seat body 10 for contacting the user. The sewage surface 102 is arranged on the inner wall of the seat body 10 for receiving flushing water. The seating surface 101 is provided with a seating sensor 110, which can be a weight sensor or the like, for sensing whether the user is seated on the toilet. The seating sensor 110 can be installed on the left side or right side of the seat body 10, for example. When the user is seated, the seating sensor 110 receives a seating signal. When the user is finished and gets up, the seating sensor 110 receives a getting-up signal.
[0031] Referring to Figure 2The seat body 10 is provided with a flushing controller 120, an upper flushing water path 130, an upper jetting port 140 and a pre-wetting mechanism 150. The flushing controller 120 is used to control the water outlet of the upper flushing water path 130. The flushing controller 120 can be connected to an external power source. The flushing controller 120 can be, for example, a conventional control chip. The water outlet of the upper flushing water path 130 is connected to the upper jetting port 140, which is used to introduce flushing water into the upper jetting port 140. The pre-wetting mechanism 150 is connected between the upper jetting port 140 and the upper flushing water path 130, which is used to introduce foam liquid into the upper jetting port 140. The foam liquid and the flushing water provided by the upper flushing water path 130 enter the sewage discharge surface 102 of the seat body 10 from the upper jetting port 140.
[0032] Further, in one embodiment, the upper flushing water path 130 includes a flushing control valve 131 and an upper flushing water pipe 132. The water inlet of the flushing control valve 131 is connected to an external water source, and the water outlet is connected to the upper flushing water pipe 132. The flushing controller 120 is electrically connected to the flushing control valve 131 to control the water pressure of the flushing control valve 131. The flushing control valve 131 can be, for example, a pulse electromagnetic valve. Through this arrangement, the flushing control valve 131 is directly connected to the external water source, and there is no need to additionally provide a water tank on the seat body 10, thereby saving space and cost.
[0033] It should be noted that in other embodiments, a water tank can also be provided in the seat body 10, and the upper flushing water path 130 is supplied with water through the water tank.
[0034] The pre-wetting mechanism 150 includes a foaming device 151, a foam outlet channel 152, a water inlet branch 153 and a liquid inlet branch 154. The water inlet branch 153 is used to supply water to the foaming device 151, and the liquid inlet branch 154 is used to supply cleaning liquid to the foaming device 151. The foaming device 151 is used to mix water and cleaning liquid to generate foam liquid. The foaming device 151 introduces the foam liquid into the upper jetting port 140 through the foam outlet channel 152.
[0035] Specifically, in one embodiment, the water inlet branch 153 can be directly connected to a built-in water tank or connected to the upper flushing control valve 131. The liquid inlet branch 154 can be in communication with an external or built-in cleaning liquid container.
[0036] Specifically, in one embodiment, the specific structure of the foaming device 151 can refer to the structure in the prior art. For example, a gas pump and a foaming chamber are provided in the foaming device 151. One or more foaming screens are provided in the foaming chamber. Air is introduced into the foaming chamber by the gas pump to form foam liquid by impacting the liquid.
[0037] Further, in one embodiment, a check valve 160 is provided between the upper flushing water channel 130 and the foam outlet channel 152. The check valve 160 is configured as a one-way valve structure to prevent the foam liquid from flowing back into the upper flushing water channel 130. Specifically, referring to Figure 3 , the foam outlet channel 152 can be configured as a three-way pipe structure, and the check valve 160 is provided at one end of the foam outlet channel 152 close to the upper flushing water channel 130.
[0038] Further, in one embodiment, the upper injection port 140 is configured with a vortex nozzle to make the sprayed liquid (the mixture of the foam liquid and the flushing water) flow out to the discharging surface 102 in a vortex shape. The vortex nozzle can be configured with a vortex chamber in the nozzle to make the sprayed liquid flow in a vortex shape. The specific shape of the vortex chamber can be configured according to actual requirements, which will not be described here.
[0039] Specifically, in one embodiment, referring to Figure 4 , the discharging surface 102 includes a circulating surface 103 and a guide surface 104, the circulating surface 103 is arranged above the guide surface 104, and the upper injection port 140 is arranged at the position of the circulating surface 103. The circulating surface 103 is arranged along the circumference of the seat body 10, and the guide surface 104 is arranged in an arc shape. The liquid sprayed by the upper injection port 140 flows in a ring shape on the circulating surface 103 and flows downward in a spiral branch along the guide surface 104. Referring to Figure 5 , the state of the sprayed liquid forming a foam layer on the discharging surface 102 of the seat body 10 is shown. Through the arrangement of the circulating surface 103 and the guide surface 104, the sprayed liquid can better cover and wet the entire discharging surface 102, further improving the flushing effect.
[0040] Further, in one embodiment, the seat body 10 further comprises a lower flushing water channel 170 and a lower injection port 180, the lower flushing water channel 170 discharges water to the discharging surface through the lower injection port 180, and the lower flushing water channel 170 is electrically connected with the flushing controller 120. The structure of the lower flushing water channel 170 can be the same as that of the upper flushing water channel 130. The flushing controller 120 can be used to control the upper flushing water channel 130 and the lower flushing water channel 170 to alternately flush the discharging surface 102, further improving the flushing effect on the toilet bowl.
[0041] In the present embodiment, the seat sensor 110 is electrically connected with the flushing controller 120 and the pre-wetting mechanism 150. Specifically, in one embodiment, the seat sensor 110 is used to control the flushing controller 120 to switch between the pre-wetting mode and the flushing mode. The flushing controller 120 controls the water pressure of the upper flushing water channel 130 in the pre-wetting mode to be lower than that in the flushing mode.
[0042] Specifically, the seat sensor 110 sends a signal to the flushing controller 120 to make the flushing controller 120 start the pre-wetting mode when receiving the seat signal, and also sends a signal to the pre-wetting mechanism 150 to make the pre-wetting mechanism 150 generate the foam liquid. The seat sensor sends a signal to the flushing controller 120 to make the flushing controller 120 start the flushing mode when receiving the off-seat signal.
[0043] The working principle of the closestool with the pre-wetting mechanism provided by the embodiment is as follows:
[0044] When a user sits down, the seat sensor 110 receives the seat signal, and the flushing controller 120 enters the pre-wetting mode. In the pre-wetting mode, the flushing controller 120 controls the water pressure of the upper flushing waterway 130 to be low, and the foaming device 151 works to generate the foam liquid which is mixed with the upper flushing waterway 130, sprayed out through the upper spraying port 140, and flows along the pollution surface 102 of the closestool in a ring shape due to inertia and then flows downward, so as to wet the entire inner cavity surface of the closestool and form a foam layer on the inner cavity surface. Because of the blocking of the foam layer, the excrement is effectively prevented from adhering to the inner cavity surface of the closestool, and the problem that the pollution surface of the closestool is difficult to flush clean is solved. After the sprayed liquid pre-wets for a certain period of time (for example, 1-3 seconds), the upper flushing waterway 130 and the pre-wetting mechanism 150 stop working.
[0045] When the user finishes using and gets off, the seat sensor 110 receives the off-seat signal, and the flushing controller 120 switches to the flushing mode. In the flushing mode, the flushing controller 120 controls the water pressure of the upper flushing waterway 130 to be high, for example, makes the flushing control valve 131 open to the maximum. At this time, the foaming device 151 does not work, and only clean water is used to flush the pollution surface of the closestool.

The embodiments shown in the drawings are shown and described merely as examples of effective applications of the principles of the present application, and the present application is not limited to any specific details of these embodiments.
[0047] Of course, upon careful consideration of the above description of representative embodiments, those skilled in the art will readily understand that various modifications, additions, substitutions, deletions, and other changes can be made to these specific embodiments, and these changes are within the scope of the principles of the present application. Therefore, the foregoing detailed description should be clearly understood as being given only by way of illustration and example, and the spirit and scope of the present application are defined solely by the appended claims and their equivalents.
