Description

Air pressure-proof floor drain core Technical Field The utility model belongs to the technical field of floor drain, and relates to an anti-air-pressure floor drain core. Background The core needs to be arranged in the sewer pipe, a U-shaped water seal section is generally additionally arranged in the sewer pipe, accumulated water is accumulated in the water seal section, and therefore gas in the sewer pipe is not easy to rise back to the room, and the sewer pipe is blocked due to accumulated water in the water seal section, so that water drainage is blocked due to the fact that air pressure possibly exists in a pipeline, for example, a floor drain core is arranged in a bathroom with a trap, and the air pressure is generated to cause unsmooth water drainage. For this reason, patent application number CN202010242133.5 discloses a balanced floor drain of atmospheric pressure, including barrel and resetting means, the upper end of barrel is the water inlet, the lower extreme of barrel is the delivery port, resetting means sets up in the lower extreme of barrel, be provided with sealed lid between resetting means and the barrel, resetting means can apply the pretightning force to sealed lid, make sealed lid hug closely the delivery port and seal the delivery port, be provided with the stroke chamber on the sealed lid, the below of stroke chamber is provided with the through-hole first with sewer pipeline UNICOM, the top of stroke chamber is provided with the external through-hole second of UNICOM, the stroke intracavity is provided with the floating member, and the floating member relies on self gravity can be sealed the through-hole first. The floating piece is arranged in the floor drain and rises under the action of air pressure difference, so that the air pressure of the lower sealing section is the same as or similar to the external air pressure, the purpose that accumulated water at the water inlet is discharged smoothly is achieved, and the floor drain has the defects that in order to realize automatic opening and closing to balance the air pressure, the position of the floating ball is always in contact with the external environment, partial water liquid easily enters the travel cavity during water discharge, dirt in the water liquid is deposited in the travel cavity to cause blockage, and when the floating ball does not work for a long time, wet dirt is air-dried by external contact, the floating ball and the inner wall of the travel cavity are tightly adhered together, so that the floating ball cannot normally lift. Therefore, one of ordinary skill in the art generally agrees to consider that 1, the size of the interval between the periphery of the floating ball and the stroke cavity is increased, the difficulty of adhering the floating ball to the inner wall of the stroke cavity due to dirt is increased, and 2, the position of the through hole II away from the water inlet is designed, so that water is prevented from being carried into the stroke cavity from the water inlet. Disclosure of Invention The utility model aims at the problems existing in the prior art, and provides an anti-air-pressure floor drain core. The aim of the utility model can be achieved by the following technical scheme: The utility model provides an prevent atmospheric pressure floor drain core, includes mounting bracket and deodorant core, the mounting bracket has down the apopore, the lower edge of this apopore department or set firmly on the deodorant core around the sealing washer of arranging of apopore down the edge, the floor drain core still includes and makes this deodorant core support up and lean on in the reset assembly of apopore shutoff down the apopore, its characterized in that, have the balanced air flue that can communicate this apopore and sewer on deodorant core or the apopore inner wall, the last edge department of apopore has and is located the manger plate portion directly over the deodorant core, the port that balanced air flue is used for communicating the apopore is located under the manger plate portion, set firmly elastic sealing member on the deodorant core, elastic sealing member's position is higher than the sealing washer, this elastic sealing member from down with balanced air flue shutoff will be synchronous drive elastic sealing member moves down and makes this balanced air flue intercommunication down the apopore and sewer when the sealing washer separates. The deodorant core produces the trend of removing up under reset assembly's effort influence, make deodorant core up and down along the mouth between the water hole realize sealed deodorant effect through the sealing washer, the water liquid is gathered and is produced down the effort to overcome reset assembly to deodorant core between deodorant core up side and the downthehole wall when the drainage, and then make deodorant core move away down and open in the downhole drain water to the sewer, reset assembly can be current setting up resp
