Detailed Description
In an embodiment, referring to the attached drawings, the pneumatic button with the air supplement structure of the invention comprises a plunger 1, an upper cover 2, a body 5, a spring 4 and a sealing element 3; the top of the plunger 1 is provided with a button (not shown); the upper cover 2 is fixedly connected with the body 5; the bottom end of the body 5 is provided with an air outlet; the spring 4 is arranged in the cavity of the body 5; the upper cover 2 is provided with a guide hole 21, the plunger 1 is movably sleeved in the guide hole 21, and the bottom of the plunger 1 extends into the cavity of the body 5; the spring 4 is propped between the bottom end of the plunger 1 and the inner bottom wall of the body 5; the bottom periphery of the plunger 1 is provided with a groove 11, the sealing element 3 is movably matched in the groove 11 so as to slide on the inner wall of the body 5 in a sealing way along with the up-and-down movement of the plunger 1, and simultaneously, the sealing element and the groove wall of the groove 11 are mutually matched to form a sealed or opened air flow channel.
Wherein,
further, a first convex ring 31 is included, the first convex ring 31 is arranged on the top surface of the sealing element 3, the first convex ring 31 is matched with the lower side of the upper groove wall of the groove 11 so as to move away from or abut against the upper groove wall of the groove 11 along with the up-and-down movement of the plunger 1; here, the first bead may also be provided in the upper groove wall of the groove 11; when the first convex ring is arranged in the upper groove wall of the groove 11, the first convex ring moves away from or is abutted to the top surface of the sealing element 3 along with the up-and-down movement of the plunger 1;
the sealing element 3 is in clearance fit with the groove bottom of the groove 11; an air inlet structure is further arranged in the groove 11; in this embodiment, the air inlet structure is one or more through holes formed at the bottom of the groove 11; a counter bore is formed in the bottom surface of the plunger 1 upwards; the through hole of the groove 11 is communicated with the counter bore; in addition, the air inlet structure may be one or more grooves radially disposed on the lower groove wall of the recess.
The outer side wall of the sealing element 3 is provided with a second convex ring 32, and the second convex ring 32 is in sealing fit with the inner side wall of the body 5;
the top periphery of the outer side wall of the body 5 is provided with a plurality of barbs 51, the periphery of the side wall of the upper cover 2 is provided with a plurality of clamping holes 22, and each clamping hole 22 of the upper cover 2 is respectively matched with the corresponding barb 51 on the outer side wall of the body in a clamping manner.
According to the pneumatic button with the air supplement structure, the sealing element 3 is in sliding sleeve with the groove 11 of the plunger 1, so that when the sealing element 3 is separated from the groove wall of the groove 11, an air flow channel is formed between a gap between the sealing element 3 and the groove wall of the groove 11 and between a through hole at the bottom of the groove and a counter bore at the bottom end of the plunger, and the air supplement is carried out from the outside to the cavity of the body 5. When the button is pressed down slightly, the sealing element 3 is in sealing fit with the body 5, so that the sealing element 3 and the body 5 are relatively static, and the plunger 1 moves downwards along the guide hole 21 under the driving of pressure, so that the upper groove wall of the groove 11 of the plunger abuts against the first convex ring 31 of the sealing element 3, and even if the air flow channel is in a sealing state, the cavity of the body 5 is in a sealing state because of being isolated from the outside. The button is pressed downwards continuously, so that the pressure of the button overcomes the friction force between the sealing element 3 and the body 5, the sealing element 3 moves downwards along with the plunger 1, and air in the cavity of the body 5 is pressed out of the air outlet while the spring 4 is compressed. At this moment, because the gas outlet of body 5 is connected with the drain valve through the hose, consequently, the gas in 5 cavitys of body can flow to the drain valve through the hose to promote the drain valve and realize the drainage function.
When the button is released, initially, the sealing element 3 and the body 5 are not moved due to friction force, and the plunger 1 moves upwards under the restoring force of the spring 4, so that the first convex ring 31 of the sealing element 3 is separated from the upper groove wall of the groove 11 of the plunger 1, even if the air flow channel is opened, the cavity of the body 5 is communicated with the outside, if the air in the cavity of the body is insufficient, the outside air enters the cavity of the body 5 from the gap between the side wall of the plunger 1 and the guide hole 21 along the opened air flow channel until the air in the cavity of the body reaches balance. Under the action of the restoring force of the spring 4, the plunger 1 finally drives the sealing piece 3 to move upwards together, and the airflow channel is kept in an open state, so that the plunger 1 can be smoothly and quickly reset.
In conclusion, compared with the pneumatic button in the prior art, the pneumatic button with the air supplementing structure has the characteristics of simple structure, sensitive and reliable air supplementing and the like.
The above embodiments are only used to further illustrate the pneumatic button with air supplement structure of the present invention, but the present invention is not limited to the embodiments, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention fall within the protection scope of the technical solution of the present invention.
