Specifically, the overflow pipe 4 is substantially in a straight pipe shape, and has a first opening end 41 and a second opening end 42, please refer to fig. 2 to 3, the first opening end 41 of the overflow pipe 4 is used for connecting with the toilet overflow device of the present invention, and the second opening end 42 of the overflow pipe 4 is connected with the water outlet 711 of the drain valve 71 disposed in the toilet tank and is commonly connected with the water outlet 72 of the toilet tank.
The joint pipe 1 is substantially cylindrical, and can be connected with the first opening end 41 of the overflow pipe 4 through a bent pipe 15, the inner channel of the joint pipe 1 is communicated with the inner channel of the overflow pipe 4, so that the negative pressure in the overflow pipe 4 can be transmitted into the joint pipe 1, the upper end and the lower end of the joint pipe 1 are respectively provided with the upper opening end 11 and the lower opening end 12, the upper sealing cover 21 and the lower sealing plug 22 which are oppositely arranged and sealed on the upper opening end 11 and the lower opening end 12 are used for offsetting the negative pressure in the overflow pipe 4, and therefore the problems that in the prior art, the overflow pipe 4 only has one sealing cover for sealing the first opening end 41, and when the sealing cover is opened, the opening force is large and/or the opening is difficult are solved.
According to one embodiment of the present invention, a connecting rod 23 is disposed between the upper sealing cap 21 and the lower sealing cap 22, and the connecting rod 23 is located in the inner passage of the joint pipe 1. The linkage between the upper sealing cover 21 and the lower sealing plug 22 is realized by arranging the connecting rod 23.
Considering that the sealing mechanism 2 is mainly used to offset the negative pressure in the overflow pipe 4, and is an optimal choice when the negative pressure in the overflow pipe 4 is completely offset, in the present embodiment, in order to completely offset the negative pressure in the overflow pipe 4, the area of the upper sealing cover 21 and the area of the lower sealing plug 22 are designed to be equal, thereby effectively solving the problem of negative pressure in the overflow pipe 4.
According to one embodiment of the present invention, the toilet overflow device further comprises a preload member 5, the preload member 5 being configured to compressively seal the upper sealing lid 21 to the upper open end 11. Since the sealing mechanism 2 itself has a function of offsetting the negative pressure in the overflow pipe 4, in order to prevent external fluid from entering the overflow pipe 4 through the joint pipe 1 in an abnormal overflow state, it is necessary to ensure good sealing of the upper opening end 11 and the lower opening end 12 of the joint pipe 1. The present embodiment mainly adopts the preload member 5 to solve the problem of sealing the joint pipe 1 from the outside.
In a possible embodiment, the preload element 5 comprises a preload spring, the preload spring 51 abutting against the upper gland 21. Specifically, a fixed frame 13 is arranged outside the upper opening end 11 of the joint pipe 1, a connecting column 14 is convexly arranged on the upper surface of the upper sealing cover 21, the connecting column 14 is connected with the fixed frame 13, the pre-tightening spring 51 is sleeved on the connecting column 14, and the upper sealing cover 21 is tightly pressed at the upper opening end 11 through the elastic force of the pre-tightening spring 51. The fixing frame 13 can fix the pre-tightening spring 51 and limit the pre-tightening spring 51.
In another possible embodiment, the preload member 5 comprises a weight member provided on the upper sealing cap 21, the pressing of the upper sealing cap 21 at the upper open end 11 being achieved by the weight of the weight member itself.
Further, in the present embodiment, in order to improve the sealing performance between the upper sealing cap 21 and the upper opening end 11 of the joint pipe 1, a sealing gasket 211 may be provided on the inner side surface of the upper sealing cap 21, so that when the upper sealing cap 21 is disposed at the upper opening end 11, the sealing between the two is effectively achieved by the cap sealing gasket 211. In addition, in order to improve the sealing performance between the lower seal plug 22 and the lower opening end 12 of the joint pipe 1, a seal ring 221 may be provided on the outer peripheral wall of the lower seal plug 22.
According to one embodiment of the utility model, the toilet overflow device further comprises a float 6, the float 6 being connected to the lower sealing plug 22. In order to realize the smooth opening of the sealing mechanism 2 from the joint pipe 1, the toilet overflow device realizes the effect of improving the buoyancy through the externally connected buoy 6, so that the lower sealing plug 22 smoothly pushes the upper sealing cover 21 to be separated from the upper opening end 11 under the action of the buoyancy and overcoming the elastic force of the pre-tightening spring or the gravity of the counterweight.
Specifically, the float 6 has a connection protrusion 61, and the connection protrusion 61 is connected to the lower seal plug 22 and can be inserted into the joint pipe 1. Further, the float 6 further includes a float body 62 surrounding the outside of the coupling protrusion 61 to provide buoyancy.
In the present embodiment, the inner diameter of the joint pipe 1 is 28mm to 32mm in order to ensure a normal overflow capacity. In order to ensure a sufficient overflow area, the upper sealing cover 21 has an opening height greater than or equal to 18 mm.
The working process of the toilet overflow device is as follows:
as shown in fig. 2, during normal operation, negative pressure exists in the overflow pipe 4, since the area of the upper stressed surface of the upper sealing cover 21 of the sealing mechanism 2 is equal to the area of the lower stressed surface of the lower sealing plug 22, the upper sealing cover 21 and the lower sealing plug 22 of the sealing mechanism 2 are stressed equally, which can be understood as internal force, and at this time, the upper stressed surface of the upper sealing cover 21 is subjected to the elastic force of the pre-tightening spring, so that the upper sealing cover 21 seals the upper open end 11 of the joint pipe 1.
As shown in fig. 3, in the overflow state, since the working water level in the toilet tank gradually rises, the float 6 receives upward buoyancy, when the buoyancy of the float 6 is greater than the elastic force of the pre-tightening spring and the friction force of the sealing gasket 211, the whole sealing mechanism 2 rises, the sealing is opened, the overflow is performed from the upper opening end 11 of the joint pipe 1, the force generated by the negative pressure of the overflow pipe 4 in the whole process is an internal force, and the float 6 does not need to overcome.
The toilet overflow device of the utility model converts the force generated by the negative pressure in the overflow pipe 4 into the internal force, the floating cylinder 6 only needs to overcome the elastic force of the pre-tightening spring 51 or the gravity of the balancing weight without overcoming the negative pressure, so the floating cylinder 6 has a smaller designable structure and a compact and easy-to-realize structure.
Second embodiment
As shown in fig. 1 to 3, the present invention further provides a toilet tank including a toilet overflow device 10 according to the first embodiment. The detailed structure, operation principle and beneficial effects of the overflow device of the toilet have been described in detail in the first embodiment, and are not described herein again.
Specifically, the toilet tank includes a tank body 7 for containing liquid, a drain valve 71 and an overflow pipe 4 are disposed in the tank body 7, and the toilet overflow device 10 is connected to a first opening end 41 of the overflow pipe 4.
Fig. 2 is a schematic view showing a configuration in which the liquid in the tank body 7 is at the operating water level, and at this time, the sealing mechanism 2 of the toilet overflow device 10 is sealed to the joint pipe 1, and the overflow pipe 4 is not in a state of being communicated with the space in the tank body 7. As shown in fig. 3, when the water inlet valve (not shown) fails and the liquid in the tank body 7 rises to the overflow water level, the toilet overflow device 10 pushes the lower sealing plug 22 of the sealing mechanism 2 to rise through the buoyancy of the liquid received by the float 6, and further pushes the upper sealing cover 21 to overcome the pre-tightening force of the pre-tightening member 5 and separate from the upper opening end 11 of the joint pipe 1, so that the liquid in the tank body 7 is smoothly discharged from the upper opening end 11, and water leakage of the toilet tank is avoided, which is specifically shown by an arrow showing a drainage flow state in fig. 3.
The toilet water tank can effectively realize the overflow of the liquid in the water tank and can prevent the problem of the leakage of the liquid in the water tank which is possibly generated due to the damage of the water inlet valve.
Third embodiment
As shown in fig. 1 to 4, the present invention further provides a toilet including the toilet tank according to the second embodiment. The detailed structure, operation principle and beneficial effects of the toilet water tank have been described in detail in the second embodiment, and are not described again here.
