Description

Technical Field

[0001] The utility model relates to the field of household sanitary ware, in particular to a toilet anti-water bend flushing structure and a toilet. Background Art

[0002] According to the drainage method, toilets are mainly divided into direct flush toilets and siphon toilets. Direct flush toilets use the impact of water flow to discharge waste. Generally, the toilet bowl wall is steeper and the water seal area is smaller, so the hydraulic force of flushing water is concentrated and the falling hydraulic force around the toilet seat is increased. The advantages are that it can discharge larger waste, is not easy to clog, and has high flushing efficiency. The disadvantages are that the flushing noise is loud, and at the same time, due to the small water seal area, it is easy to accumulate scale and has poor anti-odor effect; the drainage pipe of the siphon toilet is "∽"-shaped. After the drainage pipe is filled with water, a certain water level difference will be generated, and the waste will be discharged by the suction force generated by the flushing water in the sewage pipe in the toilet bowl. Since the siphon toilet is not flushed by the impact of water flow, the water seal area in the pool is larger, which can effectively seal the pipe odor and prevent harmful gases from the sewer from entering the room through the toilet drain pipe, and the flushing noise is relatively small.

[0003] There are two commonly used toilet sewage flushing methods at present. One is a flushing method with a fixed water trap. Although this fixed curved sewage channel with a deep water storage seals the odor, it forms a high water resistance. During the flushing process, the sewage needs to climb the slope with the water flow into the water trap, and then enter the toilet sewer sewage pipe. At the turning point of the water trap, it is easy to be stuck by larger or longer waste that is not easy to deform, causing the toilet to be blocked. Once the toilet is blocked, the water flow cannot or only reaches the discharge port at the bottom of the toilet when flushing again, and a continuous water flow cannot be formed, and a siphon phenomenon cannot be formed. Therefore, it is more difficult to discharge the blockage. At the same time, the power requirements of the toilet flushing system are relatively high, such as the head of the water pump, the water consumption, etc., which wastes water; the other is a flushing method with a rotating water trap, that is, the conversion between water seal and sewage is realized by reversing the water trap by a motor, and the purpose of water saving is achieved by reversing the water trap, but this method occupies a large space, has many folds in the middle, and is easy to harbor sewage, causing the toilet to be blocked. Therefore, it is urgent to design a toilet trap flushing structure and a toilet that can reduce the flushing resistance of the trap during the flushing process, has a compact structure, and is easy to adjust.

[0024] like Figures 1 to 3 As shown, the utility model provides a toilet trap flushing structure, comprising: a toilet body 100, on which a toilet bowl 110 is arranged;

[0025] A flexible water trap assembly 200, one end of which is disposed at the bottom of the toilet bowl 110 and communicates with the front sewage outlet at the bottom of the toilet bowl 110, and the other end of which is communicated with the sewage pipe 500 of the toilet;

[0026] A driving assembly 300, wherein the driving end of the driving assembly 300 is disposed at the upper portion of the flexible trap assembly 200, and is used to drive the flexible trap assembly 200 to move downward, so as to change the height difference between the trap and the front sewage outlet at the bottom of the toilet bowl 110, thereby achieving horizontal sewage discharge; and

[0027] The rebound component 400 is arranged on the flexible water trap component 200 and is used to drive the flexible water trap component 200 to rebound upward to change the water seal height. After the flushing is completed, when the driving component no longer applies downward force, the flexible water trap component 200 returns to its original height under the action of the rebound component 400.

[0028] During the flushing process, the utility model drives the flexible water-reflecting bend component 200 to move downward through the driving component 300 to reduce the height of the water-reflecting bend, so that the waste in the toilet does not need to go around the arched bend during discharge, reduces the resistance during flushing, realizes horizontal sewage discharge, solves the problem of high height of toilet flushing slope, achieves the effect of smooth and straight discharge, and saves water; after the flushing is completed, the flexible water-reflecting bend component 200 is driven upward by the rebound component 400 to increase the height of the water-reflecting bend, forms a water seal, ensures that the toilet bowl and the sewage pipe are leak-proof, and prevents the odor from the pipe from flowing back into the room. The overall structural design of the product is compact and easy to adjust, and it is worth promoting.

[0029] Specifically, Figure 3 As shown, the flexible water trap assembly 200 in this embodiment includes a first flexible tube 210, a ceramic S-bend 220, and a second flexible tube 230 which are connected in sequence. The open end of the first flexible tube 210 is connected to the front sewage outlet at the bottom of the toilet bowl 110, and the open end of the second flexible tube 230 is connected to the sewage pipe 500 of the toilet. In this embodiment, the open end of the first flexible tube 210 is sealed and detachably connected to the front sewage outlet at the bottom of the toilet bowl 110. The ceramic S-bend 220 is made of an integrally formed ceramic material, and its two ends are sealed and detachably connected to the first flexible tube 210 and the second flexible tube 230 respectively. The open end of the second flexible tube 230 is sealed and detachably connected to the sewage pipe 500 of the toilet. Preferably, the first flexible tube 210 and the second flexible tube 230 are retractable. The first flexible tube 210 is roughly arc-shaped, which is convenient for connecting to the front sewage outlet at the bottom of the toilet bowl 110 and one end of the ceramic S-bend 220 respectively. The second flexible tube 230 is roughly linear. In order to meet the water seal height of the national standard, the second flexible tube 230 can be adjusted up and down to a height of more than 50 mm. During the flushing process, the ceramic S-bend 220 moves downward, and the second flexible tube 230 is compressed until the height of the ceramic S-bend is roughly consistent with the height of the front sewage outlet at the bottom of the toilet bowl 110, so as to achieve horizontal sewage discharge and achieve the purpose of water saving; after the flushing is completed, the ceramic S-bend 220 moves upward, and the second flexible tube 230 is rebounded by force under the action of the rebound component 400, so that the height of the ceramic S-bend is more than 50 mm higher than the front sewage outlet at the bottom of the toilet bowl 110, so as to achieve the water seal of the anti-water bend and achieve the purpose of blocking the overflow of odor.

[0030] Specifically, Figures 1 to 3As shown, in this embodiment, the driving component 300 moves downward and abuts against the ceramic S-bend 220. In the initial state, the driving end of the driving component 300 contacts the upper surface of the ceramic S-bend 220. When the driving end of the driving component 300 moves downward, the driving end of the driving component 300 abuts against the upper surface of the ceramic S-bend 220 and applies force downward. The ceramic S-bend 220 moves downward, and the second flexible tube 230 is compressed until the height of the ceramic S-bend is roughly consistent with the height of the front sewage outlet at the bottom of the toilet bowl 110, and then the force is stopped to achieve horizontal sewage discharge.

[0031] Specifically, Figure 3 As shown, in this example, the driving assembly 300 includes a driving member 310, and a pressure plate 320 is provided at the driving end of the driving member 310, and the pressure plate 320 is arranged to move downward and abut against the ceramic S-bend 220. Preferably, the driving member 310 is an electric push rod, and the lower surface of the pressure plate 320 contacts the upper surface of the highest point of the ceramic S-bend 220. During the flushing process, after receiving the signal, the electric push rod will drive the pressure plate 320 to apply force downward to the ceramic S-bend 220, so that the lower surface of the pressure plate 320 abuts against the upper surface of the highest point of the ceramic S-bend 220. At this time, the ceramic S-bend 220 is forced to move downward, and the second flexible tube 230 is compressed until the height of the ceramic S-bend 220 is roughly consistent with the height of the front sewage outlet at the bottom of the toilet 110, and the downward pressure is stopped, so that the reverse water bend sewage discharge is transformed into horizontal sewage discharge.

[0032] Specifically, in other implementations, the driving assembly 300 may also be driven by a cylinder push rod to change the height of the ceramic S-bend 220. There is no limitation here, and those skilled in the art may design it according to their needs.

[0033] Specifically, Figure 3 As shown, the rebound assembly 400 in this embodiment includes a fixing part 410 fixed on the ceramic S-bend 220, and a connecting rod 420 extending downward is provided on the fixing part 410. The lower end of the connecting rod 420 is movably set in the toilet body 100, and an elastic part 430 is sleeved on the connecting rod 420. The upper end of the elastic part 430 abuts against the lower surface of the fixing part 410, and the lower end of the elastic part 430 abuts against the bottom wall of the toilet base.

[0034] In one embodiment, a through hole (not shown in the figure) is provided on the base of the toilet body 100 for the connecting rod 420 to slide up and down, and a accommodating cavity (not shown in the figure) is provided below the through hole. The connecting rod 420 is fixed by a nut after passing through the through hole; in another embodiment, a movable space is left between the lower end of the connecting rod 420 and the bottom wall of the toilet base, so that when the ceramic S-bend 220 moves downward, it will not affect the stress deformation of the elastic part 430.

[0035] In the initial state, the elastic member 430 is in a natural expansion and contraction state, at which time the ceramic S-bend 220 is at a high point; during the flushing process, the driving member 310 drives the pressing plate 320 to apply force downward to the ceramic S-bend 220, and the ceramic S-bend 220 drives the fixing member 410 to move downward, the elastic member 430 is compressed by force, and the second flexible tube 230 is compressed; after the flushing is completed, the pressing plate 320 moves upward, and the elastic member 430 rebounds upward under its own elastic force, driving the fixing member 410 to move upward, and then driving the ceramic S-bend 220 to move upward, thereby achieving the up and down height adjustment of the ceramic S-bend 220. Preferably, in this example, the elastic member 430 is a reset spring member.

[0036] Specifically, Figures 1 to 3 As shown, in this embodiment, there are two rebound components 400, which are symmetrically arranged on both sides of the ceramic S-bend 220. The two sets of rebound components 400 are symmetrically arranged to ensure that the first flexible tube 210 rebounds smoothly and has a better rebound height.

[0037] Specifically, Figures 1 to 3 As shown, the first flexible tube 210 and the second flexible tube 230 are both corrugated hoses. Preferably, the first flexible tube 210 and the second flexible tube 230 are plastic corrugated hoses, which can achieve rapid sealing with the front sewage outlet at the bottom of the toilet bowl 110, the ceramic S-bend and the sewer sewage pipe of the toilet, and have low cost, good sealing effect and convenient maintenance.

[0038] A toilet, characterized by comprising any one of the toilet trap flushing structures described above; and a water tank structure (not shown in the figure) arranged at the upper end of the toilet body 100.

[0039] Here's how a toilet works:

[0040] (1) When a flushing operation is required, the user presses the flush button, sending a signal to the drive assembly 300, so that the drive member 310 drives the pressure plate 320 to apply force downward to the ceramic S-bend 220, and the ceramic S-bend 220 moves downward, and the second flexible tube 230 is deformed by the force until the height of the ceramic S-bend 220 is roughly consistent with the height of the front sewage outlet at the bottom of the toilet bowl 110. The pressure plate 320 stops pressing down and remains motionless for several seconds. At this time, the water in the water tank flows through the front sewage outlet at the bottom of the toilet bowl 110 to directly discharge the sewage in the toilet bowl horizontally;

[0041] (2) After flushing, the pressure plate 320 moves upward, and the second flexible tube 230 returns to its original height under the action of the rebound component 400, so that the height of the ceramic S-bend 220 is more than 50 mm higher than the front sewage outlet at the bottom of the toilet bowl 110, forming a new water seal to prevent odor backflow.

[0042] At this point, the flushing operation of the toilet is completed.

[0043] The utility model is further described above with the help of specific embodiments, but it should be noted that the specific description here should not be understood as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
