Abstract
The utility model belongs to the technical field of floor drains, and in particular relates to a deodorization device for floor drains. The device comprises a valve body, the center of the valve body is provided with a sleeve, the sleeve is connected with the valve body through a connecting arm, a stem is inserted in the sleeve, the lower end face of the stem extends out of the sleeve, a plug chip is integrally formed, a circular groove is formed at the outer edge of the plug chip, a circular seal ring is arranged in the circular groove, a spring is clamped in the sleeve, the spring provides an upward force for the stem and enables the seal ring on the plug chip and the lower edge of the valve body to be sealed, thereby preventing gases and pests in a sewer from passing through; and when water in a floor drain, the plug chip is forced and enables the spring to be drawn, so that the water in the floor drain can enter into the sewer through the valve body. The device is simple in structure, safe and reliable.
Description
Technical field
The utility model belongs to the floor drain technical field, refers in particular to a kind of Anti-bad-smell device for floor drain.
Background technology
At present, the washroom in the building, kitchen, lavatory etc. all are provided with floor drain, can discharge from floor drain remaining in ground ponding like this, keep the clean and tidy clean of washroom, kitchen, lavatory.But after using for a long time, the insect in the sewer and foul smell can enter washroom, kitchen, lavatory by floor drain, so not only can destroy its health, and those insects carry bacterium, germ etc. more, affects resident family's health.
Summary of the invention
It is a kind of simple in structure, safe and reliable that the purpose of this utility model is to provide, the floor drain inner core that can effectively stop gas in the sewer and insect to pass through.
For achieving the above object, the utility model provides following technical scheme: a kind of Anti-bad-smell device for floor drain, comprise valve body, the central authorities of valve body are provided with sleeve, and sleeve is connected with valve body by link arm, be plugged with stem stem in the sleeve, the lower surface of stem stem is stretched out sleeve and one-body molded stifled core is arranged, and forms cannelure on the outer of stifled core, and O-ring seal is installed in the cannelure, be connected with spring in the described sleeve, spring gives the power that stem stem one makes progress and makes the lower to sealing of sealing ring and valve body on the stifled core.
The concrete structure that is connected with spring in the described sleeve is: spring housing is contained on the stem stem, and the lower end of sleeve radially inside contracts the baffle ring that forms support spring, and the upper end of stem stem is bolted with set screw, the nut of set screw with spring compression in sleeve.
The nut external diameter of described set screw is slightly less than sleeve diameter, and the upper end of sleeve is provided with seal cover.
Fitting face between described O-ring seal and the valve body is the inclined-plane, and the lower surface of described valve body inwardly forms the rib of the contact area of increase and sealing ring.
The utility model beneficial effect compared to existing technology is: valve body of the present utility model central authorities are provided with sleeve, be connected with spring in the sleeve, spring gives the power that the stem stem one in the sleeve makes progress and makes the lower to sealing of sealing ring and valve body on the stifled core, stop gas and insect in the sewer to pass through, when in the floor drain water being arranged, stifled core is stressed and spring is stretched, and the water in the floor drain can enter sewer by valve body, it is simple in structure, and is safe and reliable.
