The air inlet that gas holds 120 is connected, and first gas that multiple gas hold in 120 holds the gas outlet phase of 120 air inlet and air pump 110
Connection, multiple gas hold gas outlet of the gas outlet of last gas appearance 120 in 120 as feeder.
Wherein, air pump 110 also known as air pump, for that can exclude air from a closing space or be that closing space adds air
A kind of device.Specifically, the air pump 110 in the present embodiment is used to be to add air in closing space.
Exemplary, when air pump 110 is directly to add air in closing space, due to that can exist when air pump 110 operates
Vibrations, so as to cause gas pulsation, when the destination apparatus that need to add air disturbs for the gas pulsation in addition air event
When having higher requirement, directly adding air for closing space using air pump 110 just can not meet the requirement of destination apparatus.
Gas, which holds, 120 can store gas, when the air that air pump 110 adds not directly enters destination apparatus, but enter multiple
First gas that gas holds in 120 holds 120 air inlet, after multiple gas appearance 120 enters row buffering, is held by last gas
120 gas outlet enters destination apparatus.Hold 120 buffering by multiple gas, gas pulsation can be greatly reduced to destination apparatus
Influence.
Exemplary, the number that gas holds 120 can be 2,3,4 or 5.
Preferably, the number that gas holds 120 is 2, and in the construction shown in fig. 1, the number that gas holds 120 is 2.So
It is smooth that setting is advantageous in that air-flow can flow, and so as to which each gas 120 internal pressures of appearance are uniform, it is right to better control over air pump 110
Destination apparatus adds air, is pressurizeed.Moreover, in the case of gas pulsation impact effect identical is reduced, relative to single
The volume that gas holds shared by 120,2 gas appearances 120 is smaller, is more beneficial for the Miniaturization Design of product.
Exemplary, the volume that each gas that multiple gas hold in 120 holds 120 can be identical, also can be different.
Preferably, the volume that each gas that multiple gas hold in 120 holds 120 is identical.The gas of formed objects, which holds 120, to be ensured
The ambient condition passed through in gas flow is identical, avoids environmental difference from again leading to air-flow and changes.
Fig. 2 is the structural representation that the gas that the utility model embodiment one provides holds, as shown in Fig. 2 the present embodiment provides
Feeder in, gas hold 120 side wall may be provided with glass layer 121, for eliminating the interference of noise.
