Description

Technical Field

[0001] The utility model relates to the technical field of building sanitary equipment, in particular to an anti-blocking channel structure of a toilet. Background Art

[0002] A flush toilet is a toilet that uses the gravity of water to convert the potential energy of water into kinetic energy, thereby carrying excrement into the sewer pipe. A flush toilet generally consists of an inlet pipe, an outlet pipe, a seepage pipe, a water plug (inlet and outlet), a float, a drain knob and lever, a water replenishment mechanism, a water tank, and a toilet bowl (the toilet bowl has a curved pipe connected to the water tank).

[0003] In daily life, flush toilet blockage is a common problem in all families. When unclogging a toilet, people often use the method of continuously pouring water into the toilet bowl to raise the water level in the toilet bowl, and then use the water pressure to flush down the blockage. However, this method of unclogging with water pressure is not only less effective, but also when the blockage is more serious, sewage is easy to overflow from the toilet bowl, polluting the toilet surface and the bathroom environment; at the same time, this method of unclogging with water pressure wastes a lot of water resources and is not conducive to water conservation.

[0004] In order to solve the above problems, the patent application number 202022124818.8 discloses a splash-proof, odor-proof and anti-clogging toilet with a breaking function, including a toilet body, wherein the toilet body has a water storage structure and a toilet bowl; the water storage structure is connected to an external water source and the toilet bowl through a pipeline; the toilet bowl is connected to a flushing channel located inside the toilet body, and a liquid level is provided at the inlet end of the flushing channel corresponding to the toilet bowl; it is characterized in that the splash-proof, odor-proof and anti-clogging toilet with a breaking function also includes:

[0005] A paper discharging unit; a mounting cavity is provided in the toilet body; the paper discharging unit is arranged in the mounting cavity; the paper discharging unit includes a paper roll and a paper transfer structure; the paper transfer structure can transfer the paper roll and lay it from the toilet bowl to the liquid surface;

[0006] A crushing part; the crushing part is arranged in the extension path of the flushing channel; the crushing part includes a crushing channel cavity, a driving motor and a crushing cutter head; the crushing channel cavity is arranged in the flushing channel; the driving motor is fixed to the toilet body and the fixed end of the driving motor is correspondingly located outside the crushing channel cavity; the crushing cutter head is arranged in the crushing channel cavity, the output end of the driving motor extends into the crushing channel cavity, and the output end of the driving motor is transmission-connected to the crushing cutter head.

[0007] However, the toilet still has the following problems: although a crushing part is provided in the flushing channel to crush the obstruction, when the obstruction completely blocks the flushing channel, a large number of crushed obstructions will still remain in the original position by merely crushing the obstruction without applying a forward thrust to the obstruction, making it difficult for the obstruction to pass through the flushing channel and clear the flushing channel; at the same time, during the crushing process, a large number of crushed wet paper pieces will easily be entangled on the output shaft and blades of the motor, resulting in a larger rotation resistance of the output shaft, the motor is easily burned, the crushing effect of the blade will also be deteriorated, and the clearing effect is not ideal.

[0038] In order to prevent the pollutants in the second vertical pipe section 202 from being sucked into the second air pipe 12, the second air pipe 12 is blocked, such as Figure 2As shown, the second air pipe 12 is provided with a first one-way valve 15, which is used to prevent the liquid in the second vertical pipe section 202 from flowing back into the second air pipe 12. The first one-way valve 15 is located between the connection node between the first air pipe and the second air pipe 12 and the connection node between the second air pipe 12 and the second vertical pipe section 202.

[0039] In order to clear the blockage between the second air pipe 12 and the second vertical pipe section 202, the air supply function of the air pump 9 can be used to clear the blockage. In this embodiment, Figure 2 As shown, a fourth air pipe is provided on the first air pipe, and one end of the fourth air pipe away from the first air pipe is connected to the outside air. A second solenoid valve 11 is provided on the fourth air pipe, and the controller is controlled and connected to the second solenoid valve 11.

[0040] The controller is respectively controlled and connected with the air pump 9, the first solenoid valve 10, and the third solenoid valve 14, and the controller is arranged outside the toilet.

[0041] A baffle 3 that can be flipped downward is hinged in the second vertical pipe section 202. The baffle 3 is located below the connection node between the air intake of the negative pressure device and the second vertical pipe section 202. An elastic reset member is provided in the second vertical pipe section 202, and one end of the elastic reset member is connected to the baffle 3.

[0042] When the elastic reset member is in a natural state, the baffle 3 is in a horizontal state under the action of the elastic reset member, and the baffle 3 can block the internal passage of the second vertical pipe section 202; when the baffle 3 is flipped downward, the internal passage of the second vertical pipe section 202 is in an open state.

[0043] Specifically, Figure 3 As shown, a first hook 4 is fixedly provided at the bottom of the baffle 3, and a sidewall of the second vertical pipe section 202 is provided with an escape slot 203 which is transparent inside and outside.

[0045] The elastic reset member comprises a spring 5 , one end of the spring 5 is hooked on the first hook 4 , and the other end of the spring 5 passes through the avoidance slot and is hooked on the second hook 7 .

[0046] In order to enable the baffle plate 3 to rotate smoothly in the second vertical pipe section 202, there is generally a certain gap between the end of the baffle plate 3 away from the hinged portion with the second vertical pipe section 202 and the inner wall of the second vertical pipe section 202. In order to prevent a large amount of air in the building drainage pipe from being sucked into the second vertical pipe section 202 through the gap when the second vertical pipe section 202 is evacuated, resulting in a slow formation of a negative pressure state in the second vertical pipe section 202, in this embodiment, as shown in FIG. Figure 2 As shown, an arc-shaped water stop strip 8 is fixedly provided on the inner wall of the second vertical pipe section 202, and the arc-shaped water stop strip 8 is located above the baffle 3; when the baffle 3 is in a horizontal state, the end of the baffle 3 away from the hinged portion between it and the second vertical pipe section 202 rests against the bottom of the arc-shaped water stop strip 8, and the arc-shaped water stop strip 8 is used to seal the gap between the baffle 3 and the inner wall of the second vertical pipe section 202 at this time.

[0047] In order to prevent pollutants from being blocked by the arc-shaped water stop strip 8 and causing a large amount of retention, in this embodiment, as shown in FIG. Figure 2 As shown, the vertical cross-section of the arc-shaped water stop strip 8 is a right-angled triangle structure, and the top surface of the arc-shaped water stop strip 8 is an inclined structure sloping from top to bottom.

[0048] In order to speed up the unblocking of the toilet when it is too seriously blocked and the blocked part cannot be unblocked or the unblocking speed is too slow only by negative pressure suction, Figure 1 As shown, this embodiment also includes a toilet cleaning reaction liquid delivery pipe 17, one end of which is connected to the bottom of a discharge cone 18. The discharge cone 18 is a cone structure with a larger top and a smaller bottom. The discharge cone 18 is arranged outside the toilet.

[0049] The middle part of the toilet reaction liquid delivery pipe 17 is connected to the first drainage branch pipe 19 and the third drainage branch pipe 21. The first drainage branch pipe 19 passes through the toilet bowl 1 and is connected to the bowl space of the toilet bowl 1. The other end of the third drainage branch pipe 21 is connected to the upper top of the inclined pipe section 201.

[0050] The lower end of the toilet reaction liquid delivery pipe 17 is connected to the second liquid drainage branch pipe 20 , and the other end of the second liquid drainage branch pipe 20 is connected to the middle top of the inclined pipe section 201 .

[0051] Among them, the first drainage branch pipe 19, the second drainage branch pipe 20 and the third drainage branch pipe 21 are all provided with a second one-way valve, and the second one-way valve is used to prevent the sewage in the toilet bowl 1 and the sewage pipe 2 from flowing back into the toilet reaction liquid delivery pipe 17.

[0052] Working principle: When the sewage pipe 2 is blocked, the blocked part is generally located in the area from the first vertical pipe section to the inclined pipe section 201 of the sewage pipe 2. At this time, the negative pressure suction mode can be used first.

[0053] Negative pressure suction mode: through the controller, the first solenoid valve 10 is controlled to open, the second solenoid valve 11 and the third solenoid valve 14 are controlled to close, and the air pump 9 is turned on. At this time, the air pump 9 draws out the air in the second vertical pipe section 202, and discharges it in sequence through the second air pipe 12, the first air pipe, the air intake of the air pump 9, the air exhaust port of the air pump 9, and the third air pipe 13. The air pressure sensor 16 monitors the air pressure value in the second vertical pipe section 202 in real time, so as to provide a reference for the operator to control the time node of closing the air pump 9 through the controller.

[0054] In the process of forming negative pressure conditions in the second vertical pipe section 202, under the reset action of the spring 5 and the suction force in the second vertical pipe section 202, the end of the baffle 3 away from the hinged portion of the baffle 3 and the second vertical pipe section 202 abuts against the bottom of the arc-shaped water stop strip 8, and the arc-shaped water stop strip 8 blocks the gap between the baffle 3 and the inner wall of the second vertical pipe section 202 at this time, so that a closed space is formed in the second vertical pipe section 202. At the same time, in daily use, the baffle 3 can also prevent the odor in the building sewage pipe from entering the sewage pipe 2 in large quantities.

[0055] After negative pressure is formed in the second vertical pipe section 202, pollutants blocked in the first vertical pipe section and the inclined pipe section 201 are sucked into the second vertical pipe section 202, and the pollutants fall on the baffle 3. Then, the air pump 9 and the first solenoid valve 10 are closed, and the third solenoid valve 14 is opened, and negative pressure is formed in the second vertical pipe section 202 so that the second air pipe 12 automatically absorbs the outside air through the third air pipe 13 to balance the air pressure in the second vertical pipe section 202. Then, the baffle 3 is pushed open under the gravity of the pollutants, and the pollutants flow into the building sewage pipe along the second vertical pipe section 202.

[0056] When the blocked part still cannot be cleared under the above-mentioned natural suction conditions, a toilet-clearing reaction liquid can be poured into the lower feed cone 18. The toilet-clearing reaction liquid can be a mixture of toilet-clearing spirit or soda water and vinegar. The toilet-clearing reaction liquid enters the first drainage branch 19, the second drainage branch 20 and the third drainage branch 21 along the toilet-clearing reaction liquid delivery pipe 17. The toilet-clearing reaction liquid in the first drainage branch 19 enters the toilet bowl 1 for reaction. The toilet-clearing reaction liquid in the second drainage branch 20 enters the middle part of the inclined pipe section 201, and a part of the toilet-clearing reaction liquid infiltrates the lower end of the inclined pipe section 201 for reaction. The toilet-clearing reaction liquid in the third drainage branch 21 enters the top of the inclined pipe section 201, and a part of the toilet-clearing reaction liquid infiltrates the second vertical pipe section 202 for reaction. Then, in conjunction with the above-mentioned negative pressure suction method, the blockage in the sewage pipe 2 is cleared.

[0057] When blockage occurs at the second air pipe 12 and the second vertical pipe section 202, the air pump 9, the second solenoid valve 11, and the third solenoid valve 14 can be controlled to be opened, and the first solenoid valve 10 can be closed. The air pump 9 draws air from the outside through the third air pipe, and then the air is passed through the third air pipe 13 and the second air pipe 12 to clear the blockage and restore the connection between the second air pipe 12 and the second vertical pipe section 202.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
