Detailed Description

The technical solution for achieving the object of the present utility model is further described below through several specific embodiments, and it should be noted that the technical solution claimed in the present application includes, but is not limited to, the following embodiments.

At present, in order to prevent odor from flowing back from a sewer to a toilet through a sewage outlet of the toilet, the odor isolation of the toilet is realized, so that the comfort of the toilet is improved, and the conventional method is to arrange a section of bending section at the bottom of the toilet for storing water, so that the bending section forms a water seal to block the air flow backflow of the sewer. However, when the toilet is used, the excrement is splashed on the water cover and then the liquid in the toilet is easily splashed on the floor of the toilet and the body of a user. Therefore, in order to solve the problem of water seal odor isolation, it is proposed to use an odor isolation valve to realize the odor isolation of the toilet.

The existing odor isolation valve is generally composed of a cylindrical shell and a sealing plate, wherein the upper end of the shell is a water inlet, the lower end of the shell is a water outlet, one end of the sealing plate is hinged with the shell and positioned at the water outlet for closing the water outlet of the shell, so that the effect of isolating sewer odor is achieved. When the odor isolation valve is used, liquid discharged by the toilet bowl is communicated with excrement and acts on the sealing plate, so that the sealing plate rotates around a hinge point with the shell, the sealing plate is opened, the water outlet of the shell is also opened, the odor isolation valve is in an opened state, and the excrement is discharged from the water outlet; when excrement is washed away, the sealing plate needs to be reset, the water outlet of the shell is closed, and the whole odor isolation valve is in a closed state. Currently, in order to realize the resetting of the sealing plate, an external force generated by an additionally arranged resetting component acts on the sealing plate to reset the sealing plate, wherein the resetting component can be a torsion spring or a magnet; when the external force generated by the problem of the reset part is reduced or eliminated, the condition that the sealing plate cannot reset to block the drain outlet of the toilet occurs, and the deodorizing valve loses the deodorizing meaning.

Based on this, this embodiment discloses a special deodorization valve, under the condition of not relying on any external force, just relies on the gravity of sealing plate self just can realize sealing plate's reset, consequently whole deodorization valve's stability and durability are all better, and sealing plate's reset is less influenced by the environment, and whole deodorization valve's deodorization effect is better.

Example 1

The embodiment discloses special odor isolation valve of stool pot, referring to the attached figure 1 of the specification, the odor isolation valve is formed by a shell 1 and a sealing plate 2, wherein the shell 1 is of a cylindrical structure, the upper end is provided with a water inlet 13, the lower end is provided with a water outlet 5, the cross section of the water outlet 5 of the shell 1 is inclined, the odor isolation valve comprises an upper opening 7 and a lower opening 8, the sealing plate 2 is also obliquely arranged on the shell 1, the sealing plate 2 is hinged with clamping shafts 104 arranged on two sides of the periphery of the shell 1 through torque arms 3 symmetrically arranged on two sides, corresponding hinge points are formed at the hinge points of the sealing plate 2 and the clamping shafts, and the sealing plate 2 can reciprocally rotate around the clamping shafts 4 and comprises an open state and a closed state; further, the sealing plate 2 is of a gravity-center-offset integral structure, and the sealing plate 2 automatically rotates from an open state to a closed state by means of gravity force of the sealing plate; when the sealing plate 2 rotates reciprocally, the gravity center of the sealing plate does not pass through the plumb line L where the hinge point is located.

In this embodiment, it should be noted that, when the sealing plate 2 is in the open state, the corresponding water outlet 5 of the housing 1 is in the open state; when the sealing plate 2 is in the closed state, the drain opening 5 of the housing 1 is also in the closed state correspondingly to this time.

In this embodiment, when the sealing plate 2 is in the closed state, the tail of the sealing plate 2 contacts with the lower opening 8 of the drain opening 5, so as to achieve the effect of closing the drain opening 5; when the sealing plate 2 is in the open state, the sealing plate 2 is separated from the lower opening 8 of the drain opening 5, and the drain opening 5 is opened, and as long as the tail of the sealing plate 2 is not in contact with the lower opening 8 of the drain opening 5, the sealing plate 2 and the lower opening 8 are in the separated state, that is, the sealing plate 2 is in the open state, and the drain opening 5 is opened.

In this embodiment, it should be further explained that the torque arm 3 and the sealing plate 2 are integrally formed during processing.

In this embodiment, the drain outlet of the toilet is provided with the odor isolation valve, and the sealing plate 2 seals the drain outlet 5 of the housing 1 in a closed state, so that the entire odor isolation valve is in a closed state, and odor in the sewer can be prevented from flowing back. When the user flushes to clean the toilet bowl after using the toilet, the dirt formed by mixing tap water and excrement enters the sewage outlet, and the dirt acts on the sealing plate 2 of the odor isolation valve after reaching the sewage outlet to generate a scouring force on the sealing plate 2, so that the sealing plate 2 rotates from a closed state to an open state, the water outlet 5 of the shell 1 is opened, and the dirt can be smoothly discharged from the water outlet 5. After the dirt is discharged, because the sealing plate 2 is of a gravity-biased integral structure, the sealing plate 2 can automatically rotate from an open state to a closed state under the action of gravity, the sealing plate 2 completely relies on gravity to realize the effect of automatic reset, and then the water outlet 5 of the shell 1 is sealed, so that the odor isolation is realized. In addition, as the center of gravity of the sealing plate 2 does not reach the plumb line passing through the hinge point when the sealing plate is reciprocally rotated between the open state and the closed state, the situation that the gravity cannot be reset if the center of gravity passes through the plumb line of the hinge point in the rotation process is avoided.

Because this application special structural design, consequently, through carrying out the atress analysis to sealing plate 2, sealing plate 2 of this application can be under the condition of not additionally with the help of external force, relies on self gravity to produce a moment to sealing plate 2 completely, makes sealing plate 2 rotate around clamping axle 4 towards the lower mouth 8 direction of outlet 5, makes it just can just reset at least to just close outlet 5 of casing 1.

In the present embodiment, the deodorizing valve of the present utility model may be used in a place where deodorizing is required, such as a sewer pipe and a municipal sewage pipe, in addition to the toilet.
