Abstract
The invention provides an inflator pump, an inflating channel and an inflating method thereof. In order to reduce the vibration and the noise of the inflator pump, the inflating channel for delivering compressed air to an inflated object comprises an air inlet cavity for receiving the compressed air, an air outlet pipe for being connected with the inflated object and a cushion cavity for temporarily storing the compressed air, wherein the cushion cavity is positioned between the air inlet cavity and an air outlet channel. By inflating the inflated object (e.g. a tire) with temporarily stored air in the cushion cavity, an inflating air flow with stable air pressure can be obtained.

Embodiment
As depicted in figs. 1 and 2, cylinder head 100 has air-inlet cavity 1 and buffer cavity 2, choke rubber stopper 3 and spring 4 are set in air-inlet cavity 1, spring 4 is compressed in the top (for copper plug 5) of choke rubber stopper 3 and air-inlet cavity 1, the left side of cylinder head 100 connects gas tube 6, be formed with air outlet 20 on the chamber wall of buffer cavity 2, buffer cavity 2 communicates by air outlet 20 and gas tube 6.Buffer cavity 2 is formed at the outer ring of air-inlet cavity 1, and forms a plurality of breach 21 on the chamber wall of air-inlet cavity 1, communicates by breach 21 between buffer cavity 2 and the air-inlet cavity 1, and air-inlet cavity 1, buffer cavity 2, gas tube 6 constitute filling channel.As shown in Figure 2, pressurized gas is imported this filling channel according to the direction shown in the arrow A, pressurized gas cognition is backed down the choke rubber stopper 3 that is applied with spring force by spring 4, enter air-inlet cavity 1, pressurized gas air pressure in air-inlet cavity 1 can not decayed basically, pressurized gas cognition enters into buffer cavity 2 apace from air-inlet cavity 1, the volume of buffer cavity 2 is greater than air-inlet cavity 1, it is enough to the buffer memory pressurized gas in wherein, therefore, pressurized gas can not have the pressure decay and just enters into gas tube 6 from buffer cavity 2, buffer cavity 2 has prolonged the time that pressurized gas enters into gas tube 6, and gas tube 6 is used for and is inflated object, and for example tire joins, therefore, pressurized gas can directly not enter into closely sharp from air-inlet cavity 1 no pressure decay and be inflated object.When pressurized gas stopped to supply with, spring 4 pushed back the bottom of air-inlet cavity 1 with choke rubber stopper 3, prevented that air-flow from driving in the wrong direction, and also was that spring 4 and choke rubber stopper 3 constitute one-way valves.
As shown in Figure 3, gas-filled pump 200 comprises cylinder head 100 and air pump body as depicted in figs. 1 and 2, this air pump body has piston 7 and cylinder 8, cylinder head 100 usefulness cover the cylinder 8 of air pump body, piston 7 is moving back and forth in cylinder 8 under the effect of actuating unit, can air-breathing repeatedly, pressurized gas.In pressurized gas process (gas replenishment process), choke rubber stopper 3 is compressed gas and backs down, pressurized gas enters into the air-inlet cavity 1 in the cylinder head 100, gas in the air-inlet cavity 1 enters into buffer cavity 2 inside by four breach on the cylindrical chamber wall again, the gas of buffer cavity 2 slowly enters (time of this process is for to move upward from piston, to moving downward end) in the tire again.In breathing process, choke rubber stopper 3 is isolated with the filling channel in cylinder 8 inner spaces and the cylinder head under the effect of spring 4 owing to be cached with pressurized air in the buffer cavity 2, this moment filling channel continue to be inflated object for example tire inflate.
Embodiment's shown in Figure 3 assembly process is riveted cylinder head 100 and copper plug 5 afterwards for pack choke rubber stopper 3, choke plug spring 4, copper plug 5 etc. in air-inlet cavity 1, cylinder head 100 and steam outlet pipe 6.To rivet good cylinder head 100 again links with the motor main frame.
According to embodiment shown in Figure 3, be appreciated that inflation method of the present invention, utilize pressurized gas to inflate to being inflated object, at first in the transfer passage of pressurized gas, utilize buffer cavity 2 buffer memory pressurized gass, and then utilize the gas of the buffer memory in the buffer cavity 2 to inflate being inflated object.Can inflate constantly like this, and the stable gas pressure of output gas flow, if tire is inflated, then the air pressure in the tire can slowly increase, and can not form impulsive load to the air pump body.In this inflation method, move in cylinder 8 by piston 7 and to obtain pressurized gas, in the process of calming the anger of piston 7, utilize the gas of the buffer memory in the buffer cavity 2 to inflate to being inflated object, in the breathing process of piston 7, also utilize the gas of the buffer memory in the buffer cavity 2 to inflate to being inflated object.The used time is compared original similar air pump increases the time (being tyre inflation when having only piston to move upward) that piston moves downward.
