Description

Technical Field

[0001] The invention relates to the field of sanitary ware, and in particular to a toilet with good flushing effect. Background Art

[0002] At present, due to the prevalence of smart toilets, short ceramic water tanks or water tank-free toilets have gradually become a trend. Since the water tank needs to supply water to the brush ring water pipe, the height of the water tank needs to be designed to be higher than the toilet seat surface, so as to ensure that the working water level of the water tank is higher than the toilet seat surface, so that there is enough potential energy to flow water to the brush ring water pipe to clean the toilet bowl, and at the same time, siphon can be generated. There are pulse valves on the market that directly flush toilets, but the pulse valve has a lot of flushing noise when the water pressure is high, and when the water pressure is low, the flow is insufficient and the flushing is not clean. Of course, there are also low water tank solutions on the market, such as the solution disclosed in the patent with publication number CN105735439A, but this solution has the phenomenon of not flushing cleanly due to weak potential energy, and the brush ring of this solution is also related to the water pressure. When the water pressure is low, there is also a problem that the water flow flushing force of the brush ring tube is weak, and the surrounding wall of the toilet bowl is often not flushed clean.

[0022] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0023] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0024] like Figure 1-Figure 4 As shown, this embodiment provides a toilet with good flushing effect, such as Figure 1-Figure 4As shown, this embodiment provides a toilet, including a toilet body 1 and a flushing system 2 installed on the toilet body 1 .

[0025] The toilet body 1 is provided with a water tank 11, a jet port 12 in the toilet bowl, and a jet water channel 13 connecting the water tank 11 and the jet port 12. A water tank inlet valve 14 is installed in the water tank 11, and the water tank inlet valve 14 is connected to an external water supply pipe (not shown in the figure) and is responsible for supplying water to the water tank 11, wherein the height of the water tank 11 is equivalent to the seat surface of the toilet body 1.

[0026] The flushing system 2 includes a brush ring flushing device for flushing the surrounding walls of the toilet bowl, a jet flushing device for flushing the bottom of the toilet bowl, and a controller, wherein the brush ring flushing device includes a brush ring tube 20 arranged at the bottom of the seat ring surface and a water pump 201 installed in the water tank 11, and the water pump is connected to the brush ring tube 20 to pump water and transport it through the brush ring tube 20 for washing the surrounding walls of the toilet bowl.

[0027] The jet flushing device includes a flushing-assisting water inlet valve 21 and a water tank drain valve 22, wherein the flushing-assisting water inlet valve 21 is installed in the water tank 11, the water inlet end of the flushing-assisting water inlet valve 21 is connected to an external water pipe, and the water outlet end of the flushing-assisting water inlet valve 21 is connected to a flushing-assisting pipe 24, and the water outlet of the flushing-assisting pipe 24 is connected to the jet port 12 of the toilet body 1.

[0028] The water tank drain valve 22 is installed in the water tank 11 to control the water in the water tank to flow out from the jet port 12 of the toilet bowl through the jet channel 13.

[0029] The controller acts on the flushing-assisting water inlet valve 21 and the water tank drain valve 22 simultaneously to control the flushing-assisting water inlet valve 21 and the water tank drain valve 22 to be opened simultaneously.

[0030] When the flushing system of the toilet is flushing, the brush ring flushing device pumps water in the water tank into the brush ring pipe through a water pump to wash the surrounding wall of the toilet bowl, and the auxiliary flushing water inlet valve 21 and the water tank drain valve 22 in the jet flushing device simultaneously take in water, and the water in the water tank is discharged from the drain valve base and enters the jet port of the toilet bowl. At the same time, the water inletted by the auxiliary flushing water inlet valve 21 is discharged from the auxiliary flushing pipe 24 and enters the jet port 12 of the toilet to enhance the flow rate of the jet port. The two streams of water discharged from the auxiliary flushing water inlet valve 21 and the water tank drain valve 22 are mixed to form a strong jet force, so that the toilet can be flushed more cleanly without affecting the flushing due to the water level.

[0031] The controller can be a manual, automatic, or both manual and automatic control mode. In this embodiment, the flushing-assisting water inlet valve 21 and the water tank drain valve 22 are both air-controlled water valves. The controller is connected to the flushing-assisting water inlet valve 21 and the water tank drain valve 22 through an air inlet pipe 231. The air inlet pipe 231 can be connected to a manual or automatic or both manual and automatic controller to realize the air supply operation of the air inlet pipe 231, so as to realize the control of the flushing-assisting water inlet valve 21 and the water tank drain valve 22. At the same time, the controller is connected to the water pump signal. When the controller is activated, a start signal will be given to the water pump to start working, so as to realize the simultaneous opening of the brush ring flushing device and the jet flushing device.

[0032] Among them, reference Figure 5 and Figure 6 The flushing-assisting water inlet valve 21 includes a first valve body 210, a first water-stopping component 211 installed in the first valve body 210, and a first air-control component 212. The first air-control component 212 is linked with the first water-stopping component 211 to open the flushing-assisting water inlet valve 21.

[0033] Specifically, the first valve body 210 has a first water inlet 2101, a first water outlet 2102 and a back pressure chamber 2103. The back pressure chamber 2103 is a chamber with one end open and the other end closed. The first water stop component 211 is installed on the open end of the back pressure chamber 2103, and the first air control component 212 is installed on the closed end of the back pressure chamber 2103.

[0034] In this embodiment, a water outlet pipe 2104 connected to the flushing-assisting pipe 24 extends from the first water inlet 2101 of the first valve body 210 to the inside of the first valve body 210, and there is a gap between the outer wall of the water outlet pipe 2104 and the inner wall of the first valve body 210, and water can flow through the gap between the two and flow out from the water outlet pipe 2104. This design is not only conducive to the realization of the opening and closing of the flushing-assisting water inlet valve 21 by the first water stop component 211, but also shortens the water flow stroke between the first water inlet 2101 and the first water outlet 2102 in the flushing-assisting water inlet valve 21, which can reduce the response time during flushing.

[0035] The first water-stop assembly 211 includes a first valve core 2111 capable of moving in the first valve body 210, a first return spring 2112 for applying a return elastic force to the first valve core 2111, and a first sealing member 2113 capable of blocking the water inlet of the water outlet pipe 2104. The head of the first valve core 2111 is provided with a guide portion 2114 extending into the water outlet pipe 2104, and the guide portion and the water outlet pipe 2104 cooperate with each other to guide the movement of the first valve core 2111; the bottom of the first valve core 2111 is provided with a piston portion 2115 capable of movably sealingly contacting the back pressure chamber 2103, so that the first valve core 2111 can block one end of the back pressure chamber 2103, and the first valve core 2111 is provided with a water hole 2116 connecting the back pressure chamber 2103 and the first water inlet 2101. The first sealing member 2113 is fixedly mounted on the first valve core 2111 and has a sealing portion that is in sealing contact with the end surface of the water outlet pipe 2104 .

[0036] The first air control assembly 212 includes a first retractable airbag 2121, a pressure relief head 2122 matched with the first airbag 2121, and a second return spring 2123 for applying a return elastic force to the pressure relief head 2122. A pressure relief hole 2105 is provided on the closed end of the back pressure chamber 2103, and the pressure relief head 2122 has a blocking section extending from the pressure relief hole 2105 to the back pressure chamber 2103, and a second sealing member 2124 matched with the pressure relief hole 2105 is fixed on the blocking section.

[0037] The first air bag 2121 is connected to the air inlet pipe 231. When the air inlet pipe 231 does not supply air, under the elastic force of the second return spring 2123, the second seal 2124 on the pressure relief head 2122 blocks the pressure relief hole 2105, and external water flows into the back pressure chamber 2103 from the water hole 2116, so that the back pressure chamber 2103 maintains a higher water pressure. At the same time, the first valve core 2111 blocks the water outlet pipe 2104 under the action of the first return spring 2112, that is, at this time, the auxiliary flushing water inlet valve 21 is in a closed state.

[0038] When the air inlet pipe 231 starts to supply gas, the gas causes the first air bag 2121 to extend, causing the second sealing member 2124 on the pressure relief head 2122 to separate from the pressure relief hole 2105 and open, and the water pressure in the back pressure chamber 2103 drops rapidly. At this time, the first valve core 2111 is pushed open by the greater water pressure, so that the first sealing member 2113 on the first valve core 2111 is no longer in sealing contact with the water outlet pipe 2104, and water quickly flows from the first water inlet 2101 to the first water outlet 2102, and is finally discharged from the flushing assisting pipe 24, thereby playing a flushing assisting role.

[0039] refer to Figure 7The water tank drain valve 22 includes a second valve body 220, a second water stop component 221 installed in the second valve body 220, and a second air control component 222. The second air control component 222 is linked with the second water stop component 221 to open the water tank drain valve 22.

[0040] Specifically, the second water stop assembly 221 in this embodiment includes a valve seat 2211 and a second valve core 2212, and the second valve core 2212 has a third sealing member 2213 that can block the water hole on the valve seat 2211. The second air control assembly 222 includes a second air bag 2221 that is connected to the air inlet pipe 231 and can be extended and retracted, and the second air bag 2221 is arranged in linkage with the second valve core 2212. When the air inlet pipe 231 starts to deliver air, the second air bag 2221 stretches to raise the second valve core 2212, thereby separating the third sealing member 2213 from the valve seat 2211, and the water in the water tank 11 flows out from the injection channel 13 and finally from the injection port 12 of the toilet bowl. When the air inlet pipe 231 stops supplying air, the second valve core 2212 drops and blocks the water hole on the valve seat 2211, and the water tank inlet valve 14 in the water tank 11 continues to fill the water tank due to the drop in the water level in the water tank, so as to maintain the water level in the water tank within the set range.

[0041] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
