Description

Technical Field

[0001] The utility model relates to the field of bathrooms, in particular to a high-efficiency flushing system for toilets. Background Art

[0002] Most existing toilets use a brush ring water channel and a jet water channel to cooperate in flushing. However, due to the need to save water, appearance design and use space considerations, most current toilets tend to have miniaturized water tanks.

[0003] The traditional method of flushing toilets mainly relies on the gravitational potential energy of water. Due to the lack of water potential energy, repeated cleaning is required to clean the dirt. The method of flushing toilets mainly relying on the kinetic energy of water is often more complicated in structure and will produce greater noise during the flushing process.

[0004] In order to solve the above problems, the inventors propose the following solutions. Utility Model Content

[0005] The utility model aims to provide a toilet efficient flushing system, which has the advantages of large flow, strong power, quietness and good flushing effect.

[0009] Preferably, the second water pump is an external water pump, which is arranged outside the drain valve. With such a design, the water source used by the external water pump comes from the outside. The advantage of this solution is that the water pump does not need to be a submersible pump, which reduces the risk of failure. In addition, the external water source can reduce the consumption of internal water sources, thereby avoiding potential energy loss.

[0010] Preferably, the drain valve comprises a hydraulic chamber and a drain seat arranged at the bottom of the hydraulic chamber, the hydraulic chamber is provided with a piston which can reciprocate up and down, the drain seat is provided with the drain port, and the drain port is provided with a water sealing cover which is linked with the piston.

[0011] Preferably, a pressure relief mechanism is provided between the hydraulic chamber and the piston.

[0025] The technical solution and beneficial effects of the present utility model will be described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 4 As shown, a high-efficiency flushing system for a toilet includes a toilet seat body, and the toilet seat body includes a water tank 1 and a toilet bowl 2.

[0027] The water tank 1 is provided with a first water pump 11, a water inlet valve 12, a reversing valve 13 and a drain valve 14. The first water pump 11 is connected to the water tank 1 and the reversing valve 13. The reversing valve 13 includes a water inlet 1301, an upper water outlet 1302 and a lower water outlet 1303, and the water inlet 1301 is connected to the first water pump 11.

[0028] The toilet bowl 2 is provided with a brush ring water channel 21 , a direct flushing water pipe 22 , a bottom flushing water pipe 23 and a sewage pipe 24 .

[0029] As a preferred embodiment, specifically, the reversing valve 13 includes a cavity 131 and a float 132, wherein the cavity 131 is provided with a water inlet 1301, an upper water outlet 1302 and a lower water outlet 1303, wherein the water inlet 1301 is connected to the output end of the first water pump 11, the upper water outlet 1302 is connected to the brush circle water channel 21 through a one-sided flushing connecting pipe 11, and the lower water outlet 1303 is connected to the bottom flushing pipe 23, and the float 132 can be movably arranged between the upper water outlet 1302 and the lower water outlet 1303.

[0030] The drain valve 14 includes a body 141, a drain assembly 142 and a pressure relief mechanism 143. The body 141 includes a drain seat 1411, a fixed seat 1412, a fixed gland 1413 and a cover 1414 from bottom to top. The drain seat 1411 is connected to the bottom of the fixed seat 1412, and there is a hollow body between the drain seat 1411 and the fixed seat 1412, so that water in the water supply tank can flow in freely. The bottom of the drain seat 1411 forms a drain port 140, which is connected to the flush water pipe 22.

[0031] The drainage assembly 142 includes a second water pump 1421, a hydraulic chamber 1422 and a piston movement assembly 1423. The fixed seat 1412 and the fixed gland 1413 are buckled together to form an accommodation space, and the second water pump 1421 is provided on the left side of the accommodation space, and the hydraulic chamber 1422 is provided on the right side. The second water pump 1421 provides pressurized water for the hydraulic chamber 1422. The piston movement assembly 1423 is provided in the hydraulic chamber 1422.

[0032] like Figures 9 and 10As shown, the piston movement assembly 1423 includes a piston 4231 and a pressure cover 4232 linked to the piston 4231 , and the piston 4231 is disposed in the hydraulic chamber 1422 , and the pressure cover 4232 is disposed on the drain port 140 of the drain seat 1411 .

[0033] like Fig.11 As shown, a pressure relief mechanism 143 is provided between the hydraulic chamber 1422 and the piston 4231. Specifically, the pressure relief mechanism 143 includes a pressure relief hole 1431, a movable plug 1432 and a spring 1433. The pressure relief hole 1431 is a through hole that passes through the inner end surface of the piston 4231, and a groove 4311 is formed on the outer side of the inner end surface with the pressure relief hole 1431 as the center. The movable plug 1432 passes through the pressure relief hole 1431 and the spring 1433 and is provided on the inner end surface of the piston 4231. At the top of the hydraulic chamber 1422 is a fixed pressure cover 1413, and the fixed pressure cover 1413 has a protrusion 4131 extending downward at a position corresponding to the movable plug 1432.

[0034] The above is only a preferred embodiment of the pressure relief mechanism 143, but is not limited thereto. The structure may also be a one-way valve controlled by water pressure alone.

[0035] Using the above structure, Figure 7 As shown, in the initial state, the drain port 140 of the drain seat 1411 is in a closed state, the second water pump 1421 does not work, and the movable plug 1432 presses the pressure relief hole 1431 of the drain valve under the action of the spring 1433. At this time, the drain valve 14 is in a water storage state.

[0036] like Figure 8 As shown, the water in the hydraulic chamber 1422 is pressurized by pumping water through the second water pump 1421, and the high pressure is formed in the hydraulic chamber 1422 by the water pressure, pushing the piston 4231 up, thereby driving the gland 4232 to separate from the drain seat 1411, and realizing the drainage process. When the piston 4231 moves to the top, the protrusion 4131 of the fixed gland 1413 presses the movable plug 1432 downward, and the movable plug 1432 overcomes the elastic force of the spring 1433 and moves downward, and at the same time opens the pressure relief hole 1431 to relieve pressure, so that the water pressure in the hydraulic chamber 1422 is maintained in a relatively stable state, so that not only the service life of the motor can be extended, but also the stable operation of other structures can be guaranteed. At this time, the drain valve 14 is in the drainage state.

[0037] When the water in the water tank is drained, the water pressure in the hydraulic chamber 1422 continues to decrease, and the piston movement component 1423 is reset to the initial state under the action of gravity. Figure 7 As shown, the pressure on the spring 1433 is also released, and the spring 1433 is reset, thereby driving the movable plug 1432 to close the pressure relief hole 1431.

[0038] The toilet flushing system adopting the above structure works as follows:

[0039] Combination Figure 2 ,like Figure 5 and Figure 6 As shown, the water inlet valve 12 provides water for the water tank 1. When the toilet needs to be flushed, the control button of the toilet is triggered, and the first water pump 11 draws water from the water tank 1 to the reversing valve 13. The water is injected into the cavity 131 from the water inlet 1301. Under the action of the dynamic pressure of the water, a large friction force is generated between the float 132 and the inner wall of the cavity 131, so that the float 132 remains in the initial state (blocking the lower water outlet 1303). After the water flows through the upper water outlet 1302, it enters the brush circle water channel 21 through the face flushing port connecting pipe l1, thereby face flushing the ceramic. 0.7S before the end of the face flushing waterway, the second water pump 1421 is controlled to open the drain valve 14 synchronously, and the water outflow of the direct flushing water pipe 22 controlled by the drain valve 14 and the water outflow of the brush circle waterway 21 are synchronously gathered to form a large flow of water supply, quickly forming a siphon; at the same time, the moment the face flushing is closed, the bottom flushing water pipe 23 is opened, and at the moment the flushing forms a siphon, the bottom flushing water pipe 23 forms a pressure on the sewage outlet formed by the siphon, forming auxiliary power water, accelerating the siphon effect, and synchronously enhancing the power, so that the flushing effect is good. Due to the convergence of multiple water channels during the flushing process, the flow is large and the power is strong, not only the sound is small, but also the flushing effect is good.

[0040] The above embodiments are only for illustrating the technical idea of ​​the present utility model, and cannot be used to limit the protection scope of the present utility model. Any improvement and equivalent replacement made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
