Embodiment
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art are not under the premise of creative work is made, the every other reality that is obtained
Example is applied, belongs to the scope of the present invention.
Referring to accompanying drawing 1, a kind of washing machine, the pneumatic bumper of dryer, it includes sleeve 10, is slidably socketed in sleeve
Portion and the plunger 20 that can be slided along the central axial direction of sleeve 10, inwall and the plunger 20 of sleeve 10 extend to the inner chamber of sleeve 10
One end enclose closed air cavity 110, be additionally provided with sleeve 10 for control gas unidirectional enter air cavity 110 it is unidirectional
Air valve, level pressure valve body 130 is additionally provided with sleeve 10, when the gas pressure in air cavity 110 is more than the threshold value of level pressure valve body 130
When, level pressure valve body 130 can control the gas in air cavity 110 to discharge；Its general principle is, when plunger 20 is towards in sleeve 10
When portion moves, the inner space of air cavity 110 is compressed, the atmospheric pressure value rise in air cavity 110, when the atmospheric pressure value in air cavity 110 reaches
To level pressure valve body 130 threshold value when, the gas in air cavity 110 is leaked by level pressure valve body 130；When plunger 20 is towards sleeve 10
During external movement, the inner space increase of air cavity 110, and the atmospheric pressure value of air cavity 110 reduces, to ensure the air pressure inside of air cavity 110
Value is identical with external pressure value, and extraneous gas is entered in air cavity 110 by Non-return air valve.
Pass through above-mentioned analysis, it is obvious that the present invention in plunger towards 10 internal motion of sleeve when, pass through air cavity 110
The resistance that interior gas applies, damping effect can be achieved；By adjusting the air inflow of Non-return air valve, plunger 20 can be constrained towards sleeve
The speed of 10 external movements so that plunger 20 is limited towards the external movement process of sleeve 10 by larger resistance, realizes damping effect.
Referring to accompanying drawing 1,2, plunger 20 is slideably positioned in the one end of sleeve 10, and the other end of sleeve 10 is additionally provided with slow

320 extend to the inside of sleeve 10, and one end of second spring 330 is against end face 310, the other end against buffering end cap 340；Work as gas
During gas pressure value increase in chamber 110, gas first promotes gas column 320 to overcome the elastic force of second spring 330 and towards sleeve 10
External movement, when gas column 320 can not flex outward, if the gas pressure value in air cavity 110 further increases, level pressure valve body
130 will be opened, and the gas in air cavity 110 is discharged；It is P1 that i.e. triggering gas column 320, which flexes outward required atmospheric pressure value, is touched
Sending out level pressure valve body 130, outwards discouraged required atmospheric pressure value is P2, and P2 is more than P1.
Referring to accompanying drawing 1, the centre bore 210 to match with gas column 320, the hole depth of centre bore 210 are additionally provided with plunger 20
During the outside maximum extension state of the minimum length extended to less than gas column 320 in sleeve 10, i.e. gas column 320, in sleeve 10
The length of gas column 320 be more than centre bore 210 length；It the advantage is that, offseted using gas column 320 and centre bore 210, can be to post
Plug 20 carries out spacing.
More optimally, the link position of Non-return air valve 120, level pressure valve body 130 and sleeve 10 closes on sleeve connection buffering
The side of element 30, when plunger 20 gos deep into the range in sleeve 10, plunger 20 does not influence Non-return air valve 120, level pressure valve body 130
With the connection of air cavity 110；Because gas column 320 and centre bore 210 match, to the position-limiting action of plunger 20, it is ensured that plunger 20
The connection of Non-return air valve 120, level pressure valve body 130 and air cavity 110 is not influenceed.
Referring to accompanying drawing 1,2, gas column 320, centre bore 210,10 equal coaxial line of sleeve arrangement, buffering end cap 340 and sleeve
End is connected through a screw thread, and buffering end cap 340 is articulated with the outer barrel of washing machine or dry cleaner, and plunger deviates one end of sleeve 10
Side and the casing of washing machine or dry cleaner are hinged.
Referring to accompanying drawing 1,2, above-mentioned Non-return air valve 120 includes the air valve wall portion connected with air cavity 110, is lived in air valve wall portion
Dynamic to be provided with only balloon 121, only balloon 121 is used to control gas unidirectional to flow into air cavity 110.
Referring to accompanying drawing 1,3, above-mentioned level pressure valve body 130 include with air cavity 110 connect valve body wall portion, be installed on valve body wall
In portion and it is used for the only air cover board 131 for blocking air cavity 110 and valve body wall portion interface, is additionally provided with valve body wall portion for pushing away
Dynamic only air cover board 131 towards air cavity 110 and the first spring 133 of valve body wall portion interface motion, be provided with valve body wall portion with
Bleeder port 134 that is that its inner chamber is connected and being discharged for gas.
More optimally, be also equipped with being vented spiral cover 132 on the end face of valve body wall portion, one end of the first spring 133 against
Spiral cover 132, the other end are vented against only air cover board 131.
More optimally, air cavity 110 and valve body wall portion interface are in frustum opening, and only air cover board 131 and frustum
The shape of opening matches.
