Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] EMBODIMENT

[0028] In combination with Figures 1 to 3 ​As shown, the present embodiment provides a toilet, comprising a toilet body 1, a sewage passage connected to the bottom of the toilet body 1, a first flushing pipeline 2 connected to the inner wall side of the toilet body 1, a second flushing pipeline 3 connected to the sewage passage of the toilet body 1; further comprising a third flushing pipeline 4.

[0029] The sewage passage comprises a first section 5 connected to the cavity of the toilet body 1, a second section 6 connected to the sewage pipeline, and a third section 7 for connecting the first section 5 and the second section 6; the third flushing pipeline 4 is connected to the third section 7.

[0030] In the present embodiment, as shown in Figure 1 and Figure 2 As shown, taking a siphon toilet and a straight flushing toilet as examples, the difference between them is that the siphon pipeline passage of the siphon toilet is S-shaped as a whole, which can produce a siphon effect; while the straight flushing pipeline passage of the straight flushing toilet is relatively large, which will not produce a siphon effect, but only rely on water flow to flush straight. Specifically, the first flushing pipeline 2, the second flushing pipeline 3 and the third flushing pipeline 4 are respectively connected to the water pipeline system, and are independently controlled or synchronously controlled to open or close. In the siphon toilet, the third flushing pipeline 4 is connected to the outer bend side of the third section 7, and the flushing port of the third flushing pipeline 4 is arranged towards the downstream of the pipeline. When the sewage passage is not blocked, for the siphon toilet, the third flushing pipeline 4 flushes the sewage passage, which can quickly form negative pressure in the sewage passage, strengthen the siphon effect, and thus quickly discharge the sewage and dirt, reducing the occurrence of blockage; while for the straight flushing toilet, the third flushing pipeline 4 flushes the dirt in the third section 7 flushed by the first flushing pipeline 2 and the second flushing pipeline 3 with high pressure, which can quickly flush the dirt away from the third section, thereby avoiding the blockage of the third section 7. When the third section 7 is blocked, whether it is a siphon toilet or a straight flushing toilet, the high-pressure water of the third flushing pipeline 4 can effectively flush away the blockage, thereby solving the problem of blockage.

[0031] Among them, the first flushing pipeline 2 and the second flushing pipeline 3 can also be connected through, for example, Figure 4 and Figure 5The anhydrous tank type mechanical valve 12 shown is controlled, and the specific structure is disclosed in the application number 202111602783.7, which is not described in detail here. The third flushing pipeline can be controlled by a separate control valve. The anhydrous tank type mechanical valve controls the main control piston to complete one reciprocating motion through the delay setting of the starting chamber, and the main control piston controls the flow passage switching mechanism to switch out the water pipeline during the process, thereby pushing the water flow to complete the whole process of outer ring flushing, jet flushing and outer ring secondary flushing. The whole process is completed by mechanical force, without relying on the power of the water tank.

[0032] In another embodiment, as Figure 3 shown, it also includes a water storage tank and a pressure boosting device; the water inlet of the water storage tank is connected to the waterway system through the communication pipe 11, and the water outlet is connected to the third flushing pipeline 4; the pressure boosting device is used to pressurize the water in the water storage tank and accelerate the flow from the third flushing pipeline 4.

[0033] Specifically, the pressure boosting device is a gas pump 10; the water storage tank includes a first water storage tank 8 and a second water storage tank 9 connected to the first water storage tank 8; the water inlet is provided on the first water storage tank 8; the water outlet is provided on the second water storage tank 9 and is provided with a first electromagnetic valve; the communication between the first water storage tank 8 and the second water storage tank 9 is provided with a second electromagnetic valve; the gas pump 10 is connected to the air inlet of the second water storage tank 9. The first electromagnetic valve and the second electromagnetic valve can form a sealed chamber when the gas pump 10 pressurizes the second water storage tank 9. When the second water storage tank 9 is full of water, the first electromagnetic valve and the second electromagnetic valve are closed at this time, so that the second water storage tank 9 is in a closed state, and then the gas pump 10 pumps gas into the second water storage tank 9 to pressurize the second water storage tank 9; when the pressure reaches a certain value, the first electromagnetic valve is opened, and at this time, water with high water pressure is obtained, which can greatly enhance the siphon effect of the sewage passage, or directly flush away the dirt blocked on the third section 7, solving the problem of blockage at the bend. Of course, it should be noted that the air inlet should be arranged on the upper side of the second water storage tank 9 and placed on the water level to avoid backflow of water into the gas pump 10.

[0034] Preferably, a liquid level sensor is arranged in the second water storage tank 9; the water inlet is provided with a fourth electromagnetic valve electrically connected with the liquid level sensor. When the liquid level sensor detects that the water in the second water storage tank 9 is insufficient, the fourth electromagnetic valve opens the water inlet to store water in the second water storage tank 9, and when the water pressure in the water system is insufficient, the water in the tank can be used as backup water. When the liquid level sensor detects that the water in the second water storage tank 9 is stored to a set height, the fourth electromagnetic valve closes the water inlet to avoid the liquid level being too high, causing water to flow back into the air pump 10.

[0035] Further, a third electromagnetic valve is arranged on the air inlet, and the third electromagnetic valve closes the air inlet when the second water storage tank 9 is being filled with water, thereby avoiding the second water storage tank 9 being filled with water to cause water to flow back into the air pump 10.

[0036] Preferably, a one-way valve is further arranged on the third flushing pipeline 4 to avoid sewage in the sewage discharge channel flowing back into the water storage tank.

[0037] It should be noted that the above-mentioned toilet can be a connected toilet, a split toilet, or a wall-hung toilet, a floor-standing toilet, and an intelligent toilet, and the like, which are not specifically limited herein.
