Abstract

The utility model discloses an anti-air trapping structure of a pneumatic button. The anti-air trapping structure of the pneumatic button comprises an air cavity body, a button and a sealing element, wherein the sealing element is sleeved on the bottom of the button and slides along with the up-down motion of the button in a sealing mode, and an air leakage structure which enabled the air cavity body to be communicated with the outside air when the button is started and returned back is arranged on the air cavity body. Due to the fact that the air leakage structure which enables the air cavity body to be communicated with the outside air when the button is returned back is arranged on the wall of the air cavity body of the pneumatic button, air is not trapped in the pneumatic button under the condition that the button is pressed rapidly, a drain valve can return back after the button is released, output volume of the drain valve is stabilized, and hidden danger of water leakage is avoided.

Description

The anti-tired depressed structure of a kind of Pneumatic button

Technical field

The utility model belongs to the Pneumatic button technical field, is specifically related to the anti-tired depressed structure of a kind of Pneumatic button.

Background technology

Pneumatic button is the control device of applied Pneumatic drainage valve on the present bathroom market, Pneumatic button of the prior art has making-up air device, but in the situation about can't effectively lose heart in excessive tonifying Qi, the closing of draining valve will be affected and cause not closing, close time-delay or can not close fully, causes the waste of water resource.

The utility model content

The purpose of this utility model is to overcome the prior art defective, provides a kind of Pneumatic button anti-tired depressed structure.

The technical solution of the utility model is as follows:

The anti-tired depressed structure of a kind of Pneumatic button, comprise an air cavity, a button and a seal, sealing member sheathing is in the bottom of button, and along with moving up and down in the inwall sealing of air cavity of button slided, described air cavity is provided with the bleed structure that air cavity can be connected with outside air when the button initial sum was resetted.

In a preferred embodiment of the present utility model, described bleed structure is at least one through hole that is located on the air cavity body wall, the below of the lower limb of the seal when this through hole is positioned at described button and is in the initial sum reset mode.

In a preferred embodiment of the present utility model, the aperture of described through hole is 0.2 ~ 5mm.

In a preferred embodiment of the present utility model, described bleed structure is at least one push rod to downward-extension that is installed in the air cavity inside top surface, so that seal generation deformation separates with the body wall of air cavity during push-button reset.

In a preferred embodiment of the present utility model, described seal is a sealing ring.

The beneficial effects of the utility model are:

1, the utility model is provided with the bleed structure that air cavity can be connected with outside air when making push-button reset at the air cavity body wall of Pneumatic button, so that in the situation of pressing fast, be not stranded gas in the Pneumatic button, draining valve can reset immediately behind the release button, stablize the discharge capacity of draining valve, avoided the hidden danger of leaking;

2, the utility model adopt the through hole or be located on the air cavity body wall be installed in the air cavity inside top surface to the push rod of downward-extension as bleed structure, such is simple in structure, can be directly used in the improvement to existing product, has reduced to produce and has improved cost.

The specific embodiment

Below by the specific embodiment in connection with accompanying drawing, the technical solution of the utility model is further detailed and describes.

Embodiment 1

As depicted in figs. 1 and 2, the anti-tired depressed structure of a kind of Pneumatic button, comprise an air cavity 10, a button 11 and a sealing ring 12, sealing ring 12 is sleeved on the bottom of button 11, and along with moving up and down in the inwall sealing of air cavity 10 of button 11 slided, the below of the lower limb of sealing ring 12 when the through hole 101 that described air cavity 10 body walls are provided with, this through hole 101 are positioned at button 11 and reset.

When button 11 during in original position, air cavity 10 is connected with outside air by through hole 101; After pressing 11 buttons, sealing ring 12 moves downward through this through hole 101 with button 11, and the cavity of through hole below 101 carries out pneumatic control by sealing ring 112 and outside air seal isolation to draining valve; When stopping to press button 11, sealing ring 12 resets gradually with button 11, after passing through above-mentioned through hole 101, air cavity 10 can be connected with outside air, accelerate air cavity 10 lose heart and and make the Rapid reset of button 11, the aperture of this through hole 101 is 0.2 ~ 5mm, preferred 1mm.

Embodiment 2

As shown in Figure 3 and Figure 4, the anti-tired depressed structure of a kind of Pneumatic button, comprise an air cavity 10, a button 11 and a sealing ring 12, sealing ring 12 is sleeved on the bottom of button 11, and along with moving up and down in the inwall sealing of air cavity 10 of button 11 slided, the inside top surface of described air cavity 10 is provided with the push rod 101 to downward-extension.

When button 11 during in original position, the edge of push rod 101 contact sealing rings 12 makes the deformation of sealing ring 12, and this moment, air cavity 10 was connected with outside air; After pressing button 11, sealing ring 12 moves down the contact that breaks away from gradually push rod 101 with button 11, the edge shape of sealing ring 12 recovers the sealing with air cavity 10 body walls, and the following cavity of push rod passes through sealing ring 12 and outside air seal isolation, and draining valve is carried out pneumatic control; When stopping to press 11 buttons, sealing ring 12 resets gradually with button 11, and when the above-mentioned push rod 101 of contact, the edge of sealing ring 12 along with the contact of push rod 101 deformation occurs, so that air cavity 10 can be connected with outside air, accelerate losing heart and and making the Rapid reset of button 11 of air cavity 10.

The above, it only is preferred embodiment of the present utility model, so can not limit according to this scope that the utility model is implemented, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
