Embodiment
As shown in Figure 1 to Figure 3, the utility model is a kind of electromagnetic gas valve 1, is arranged on one and has in the inflating and exhausting system of air pump 2 and inflate inflator 3; In diagram, described inflator 3 is airbag groups.This electromagnetic gas valve 1 has a housing 10, a gas-entered passageway 20 that can be communicated with air pump 2 air outlet is provided with in described housing 10, one is positioned at the check valve 30 on gas-entered passageway 20, one putting chamber 21 being positioned at gas-entered passageway 20 downstream, one group is arranged on the self-holding electromagnetic valve bar 40 that can accept the excitatory effect of a coil 41 and displacement in putting chamber 21, and the air chamber 22 that is communicated in putting chamber 21 downstream, this air chamber 22 has the gas tube 23 of a connection inflator 3, and the leakage port 24 that is communicated to outside atmosphere, wherein, described self-holding electromagnetic valve bar 40 wherein one end is resisted against leakage port 24, this leakage port 24 is made to keep normally closed, this self-holding electromagnetic valve bar 40 the other end then keeps spacing with gas-entered passageway 20.During enforcement, described air pump 2, coil 41 are controlled by a control module 4.
Aforementioned coil 41 is arranged on the periphery of putting chamber 21; These self-holding electromagnetic valve bar 40 two ends are respectively equipped with leak-stopping valve plug 42, the gap 43 having between self-holding electromagnetic valve bar 40 periphery and supply air circulation is enclosed in putting chamber 21, and be provided with a spring 44 bottom putting chamber 21 and be resisted against this self-holding electromagnetic valve bar 40, make the leak-stopping valve plug 42 at self-holding electromagnetic valve bar 40 top can keep closing leakage port 24.
Moreover, a valve seat 45 arranged for coil 41 is provided with between gas-entered passageway 20 and putting chamber 21, be provided with an entrance 451 bottom this valve seat 45 to be communicated with gas-entered passageway 20, top is provided with one and protrudes from outlet 452 bottom putting chamber 21, and aforementioned self-holding electromagnetic valve bar 40 keeps spacing with outlet 452.In addition, can really flow according to the direction of setup control in order to ensure air-flow, the appropriate location between housing 10 inside and other composition elements, should arrange leakproof element and leak to prevent air-flow.Such as in diagram, bottom valve seat 45 and between periphery and housing 10, be provided with some leak-stopping cushion rubbers 453, housing 10 inner space can be allowed to form air-tight state by means of this leak-stopping cushion rubber 453, and then prevent the air-flow entered in housing 10 from leaking.
As shown in Figure 4, when control module 4 makes air pump 2 come into operation, when making gas-entered passageway 20 air inlet, because gas tube 23 keeps the state often opened, air draught can directly be inflated by the entrance 451 of check valve 30, valve seat 45 and outlet 452, putting chamber 21, air chamber 22 and gas tube 23 pairs of inflators 3; As shown in Figure 3, when the air pressure in inflator 3 has reached the saturation ratio of needs, make air pump 2 decommission air inlet, then namely reverse in inflator 3 air pressure can keep the air pressure in inflator 3 by check valve 30; Now the non-power consumption of electromagnetic gas valve 1 just can reach the object of inflation, the rear sealing of inflation.
As shown in Figure 5, if inflator 3 is too saturated and when needing disappointing, described control module 4 makes self-holding electromagnetic valve bar 40 by the excitatory effect of coil 41 to bottom offset and after Compress Spring 44, leak-stopping valve plug 42 bottom self-holding electromagnetic valve bar 40 can be resisted against the outlet 452 of valve seat 45, and then closed gas-entered passageway 20, open leakage port 24, then the air in inflator 3 can oppositely be discharged by leakage port 24 via after gas tube 23, air chamber 22 simultaneously; Now electromagnetic gas valve 1 need consume once excitatory electric power, just reaches the object stopping inflation and exhaust simultaneously.
In addition, the outside of described leakage port 24 is provided with a bloop 50 (bubble silk floss or PE agglomerate), allows electromagnetic gas valve 1 avoid air-flow to produce noise when carrying out exhaust.
More than illustrate the utility model just illustrative; and nonrestrictive, those of ordinary skill in the art understand, when not departing from the spirit and scope that claim limits; many amendments, change or equivalence can be made, but all will fall within protection domain of the present utility model.
