The model utility content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of simple in structure, and is easy for installation, and exhaust is automatic air intake-exhaust valve smoothly.
To achieve these goals, the utility model adopts following technological scheme:
A kind of automatic air intake-exhaust valve, comprise valve body, piston and elastic component, described valve body comprises main cavity and the first passage and the second channel that link to each other with described main cavity, described main cavity one end is provided with exhaust part, described exhaust part lower end is connected with described elastic component and is positioned at described main cavity, fixedly there is the described piston that can move described elastic component lower end in described main cavity, the interior wall seamless of wherein said piston and described main cavity joins.
Further, the described main cavity the other end is provided with end cap.
Further, described end cap is provided with magnet.
Further, described magnet is provided with rubber cushion.
Further, during described elastic component deformation, described piston breaks away from described magnet magnetic attraction, and described piston is positioned at described first passage and described second channel top.
Further, when described piston was inhaled mutually with described magnet, described piston was between described first passage and described second channel, and described second channel communicates with described exhaust part.
Further, described exhaust part is provided with exhaust port.
Further, described elastic component is hollow.
Compared with prior art, the utility model is simple in structure, and is easy for installation, and stable gas pressure in the process in treatment makes exhaust smooth and easy, and cheap, uses reliably, can reach good result for the treatment of.
Description of drawings
Fig. 1 is in the schematic representation of original state for elastic component of the present utility model;
Fig. 2 is the schematic representation that elastic component of the present utility model is in compressive state.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See also Fig. 1, the utility model has disclosed a kind of automatic air intake-exhaust valve 1, comprises valve body 11, piston 12, elastic component 13.
Described valve body 11 comprises main cavity 111, and the first passage 112 and the second channel 113 that link to each other with described main cavity 111, and described first passage 112 is provided with a suction port 1121, and described second channel 113 is provided with a suction port 1131.
Described main cavity 111 1 ends are provided with an exhaust part 14, and described exhaust part 14 is provided with an exhaust port 141.Described exhaust part 14 lower ends are connected with described elastic component 13, and described exhaust part 14 lower ends are positioned at described main cavity 111.Described elastic component 13 is hollow, and the described exhaust port 141 of described exhaust part 14 is positioned at described elastic component 13 tops.Fixedly there is the described piston 12 that can move described elastic component 13 lower ends in described main cavity 111, wherein said piston 12 joins with the interior wall seamless of described main cavity 111.
Described main cavity 111 the other ends are provided with an end cap 15, and described end cap 15 is provided with a magnet 16, and described magnet 16 produces the described piston 12 of magnetic field suction.Described magnet 16 is provided with a rubber cushion 17, the thickness of described rubber cushion 17 is more thick, the direct suction of 16 pairs of described pistons 12 of described magnet is just more little, can pass through the thickness of the described rubber cushion 17 of the described automatic air intake-exhaust valve 1 of change, and then change the magnetic attraction between described magnet 16 and the described piston 12.
See also Fig. 1 and Fig. 2, during original state, described magnet 16 produces the described piston 12 of magnetic field suction, and described second channel 113 is communicated with ambient atmosphere 18, isolates by described piston 12 between described first passage 112 and the described second channel 113.
When inflation, gas is entered in the described first passage 112 by described suction port 1121, and described first passage 112 air pressure reach setting value, even described piston 12 breaks away from the value of described magnet 16 magnetic attraction.Change the thickness of described rubber cushion 17, just can change the magnetic attraction between described magnet 16 and the described piston 12, and then can change the air pressure setting value of described first passage 112, to satisfy different needs.The air pressure of described first passage 112 is greater than the air pressure of described second channel 113, because gas pressure effect, described piston 12 breaks away from described magnet 16 magnetic attraction, compress described elastic component 13, described elastic component 13 produces deformation, and described piston 12 is positioned at described first passage 112 and described second channel 113 tops, make described first passage 112 and the described second channel 113 formation gas fill port that is interconnected, inflate, described second channel 113 is isolated by described piston 12 with described ambient atmosphere 18.
When exhaust, described first passage 112 air pressure reduce, gas is earlier by described first passage 112 dischargings, after air pressure is less than described elastic component 13 elastic force, compressed described elastic component 13 recovers, described elastic component 13 forces described piston 12 to get back to original state, described magnet 16 attracts described piston 12, described piston 12 is between described first passage 112 and described second channel 113, and described second channel 113 communicates with described exhaust part 14, and then described second channel 113 is communicated with the formation exhaust passageway with described ambient atmosphere 18, gas is via the described elastic component 13 and the described exhaust port 141 that is positioned at the described exhaust part 14 of described elastic component 13 tops of hollow, final gas reaches the purpose of exhaust by being discharged in the described ambient atmosphere 18 in the described second channel 113.
