Description
Technical field
The present invention relates to a kind of air interchanger, promptly a kind of aerating and exhaust device that is used for air bed or other inflatable object.
Background technique
A lot of inflation appliances are arranged in the market, and as air bed etc., this inflation appliance adopts the inflator inflation in use.Generally, inflator comprises external pump or built-in gas-filled pump.External pump need manually be inflated, and wastes time and energy, and the gas-filled pump that is built in gradually in the air bag of inflation appliance replaces.Yet this kind gas-filled pump usually can only be to airbag aeration, and can't exit, and when desire was exitted, people can only squat down on the ground usually, with the manual one-way valve of pinning gas-filled pump, it is opened, and exits, and it is very inconvenient to operate.Even adopt solenoid valve automatically one-way valve to be backed down, the gas in the air bag can not be discharged totally fully, and need be with artificial mode extruding gasbag, for large-scale inflation appliances such as air beds, this venting mode is required great effort very much.
Summary of the invention
The object of the present invention is to provide a kind of air interchanger, this device not only can be to airbag aeration, also can be conveniently to air bag deflation, and the gas in the air bag can be discharged totally fully.
For achieving the above object, technical solution of the present invention is: a kind of air interchanger, comprise air pump and air pump seat, have vent on the air pump seat, whether it is ventilated by one-way valve control, and this device is when inflation, and the inlet hole of air pump communicates with the external space of air bag, exhaust port communicates with the interior space of air bag, and one-way valve is in open mode under the effect of gas pressure; When venting, the exhaust port of air pump communicates with the external space of air bag, and inlet hole communicates with the interior space of air bag, and one-way valve is in open mode under the effect of external force.
Have inlet hole and exhaust port on the ccontaining vaned body sidewall of this air pump, inlet hole is positioned at the axis top of blade, and exhaust port is positioned at the tangent position of blade.
This body is arranged with middle tube outward, has inflation inlet hole, inflation exhaust port, venting inlet hole and venting exhaust port in this on the sidewall of tube, and the inflation inlet hole is respectively equipped with air flue with the venting exhaust port and communicates with space outerpace; During inflation, the inlet hole of body is corresponding with the inflation inlet hole of middle tube, and exhaust port is corresponding with the inflation exhaust port of middle tube; During venting, the inlet hole of body is corresponding with the venting inlet hole of middle tube, and exhaust port is corresponding with the venting exhaust port of middle tube.
The panels outside of this air pump seat is provided with and can drives the body rotation to switch to the handwheel of diverse location.
This body below is installed with one can be with the cam of body rotation, and cam is corresponding with the valve rod of one-way valve, and its major diameter can back down one-way valve.
End face is provided with inlet hole and exhaust port on the ccontaining vaned body of this air pump, and inlet hole is positioned on the axis of blade, the tangent position that is positioned at blade of exhaust port correspondence.
This body top is provided with a ventilation core, and the medial axis of ventilation core forms flaring vent from top to bottom; During inflation, this tubaeform vent communicates with the inlet hole of body; During venting, this tubaeform vent communicates with the exhaust port of body.
The panels outside of this air pump seat is provided with and can drives the rotation of ventilation core to switch to the handwheel of diverse location.
This ventilation core is provided with cam, and cam is corresponding with the valve rod of one-way valve, and its major diameter can back down one-way valve.
This device is provided with a ventilation tube, and an end of ventilation tube communicates with space outerpace, and the other end is selected the inlet hole and the exhaust port of corresponding body.
This ventilation tube is when venting, and its outer wall just in time is butted on the valve rod of one-way valve, and one-way valve is backed down.
After adopting such scheme, because the airflow direction of air pump of the present invention inside is constant, and only need change the position that communicates of inlet hole, exhaust port with the air bag interior or exterior space of air pump, can change the gaseity that charges and discharge of air bag, therefore not only can be to airbag aeration, also can be conveniently to air bag deflation; In addition, because the present invention to air bag deflation the time, also uses air pump, promptly replace manual type, so the gas in the air bag can be discharged totally fully in electronic mode.
