Description

Inflator

technical field

Background technique

As shown in FIG. 1 , it is an inflating device 1 with a spring installed inside, which can be automatically reshaped by the elastic support of the spring 11 . When this inflating device 1 is used, the air in the inner space of the capsule body 12 is extruded to inflate by compressing and deforming a capsule body 12 containing the spring 11, and then the spring 11 is elastically compressed. The accumulated elastic force pushes up the balloon body 12 again and restores its shape. When the wire diameter of the spring 11 adopted is relatively thick, the elastic supporting force of the spring 11 will be improved, which will help to speed up the recovery speed of the capsule body 12, but this will increase the weight and manufacturing cost of the pumping device 1; and if When using a spring 11 with a smaller wire diameter, although the weight and manufacturing cost can be reduced, the capsule body 12 will be reshaped at a slower rate due to the smaller elastic force, which will affect the pumping speed. Therefore, how to increase the wire diameter of the spring 11 In the case of the case, improving the reshaping speed of the capsule 12 is a problem that the industry is eager to solve.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

As shown in Figures 2, 3 and 4, the preferred embodiment of the utility model inflating device is suitable for connecting and installing on an object 900 that can be inflated and inflated to inflate the object 900. The object 900 can be Balloons, air cushions or inflatable beds, etc. The inflating device comprises a hollow flexible airbag mechanism 3, a spring 4 installed in the airbag mechanism 3, a closed sleeve 5 installed in the airbag mechanism 3, and a plurality of complex parts installed in the airbag mechanism 3 6.

The air bag mechanism 3 includes a hollow flexible soft bag 31 defining an air chamber 310 inside, and an air intake head 32 and a non-return air outlet member 33 respectively connected to the soft bag 31 . The soft bag 31 is made of flexible deformable air-tight plastic material, has a bottom wall 311, a ring wall 312 protruding upward from the periphery of the bottom wall 311, and a ring wall 312 fixed on the top of the ring wall 312. The edge cooperates with the bottom wall 311 and the ring wall 312 to define the top wall 313 of the air chamber 310 . The intake head 32 is fixed on the top wall 313 to communicate with the air chamber 310 .

The non-return air outlet part 33 is installed and fixed on the ring wall 312 , communicates with the air chamber 310 , and is used for communicating with the object 900 to be inflated. The non-return air outlet part 33 is made of soft plastic material, and is in the shape of a flat tube, including two flexible flexible parts that extend outward from the soft bag 31 and are connected to each other by their two long sides 332. The plastic sheet 331, and the opposite inner surface of the plastic sheet 331 is smooth, and can be airtightly attached to each other. The plastic sheet 331 can be flushed by the gas extruded by the air chamber 310, and becomes an open state of the exhaust channel 330 connecting the air chamber 310 and the object 900, and can be reshaped by the air chamber 310. The generated negative pressure suction attracts and changes between the closed state of the opposite airtight adsorption and bonding. When it is in the open state, gas can be introduced into the object 900 for inflation, and when it is in the closed state, it will be airtightly isolated between the air chamber 310 and the object 900 .

The spring 4 is installed in the soft bag 31 so as to be elastically compressible downward, and elastically resists up and down between the top wall 313 and the bottom wall 311 , and has a constant elastic force to stretch the soft bag 31 up and down.

The complex parts 6 are respectively covered and fixed in the ring wall 312 at intervals around the axis of the soft capsule 31, and are in the shape of an upright sheet, which can be elastically deformed together with the bending deformation of the soft capsule 31, and has an upper and lower shape. The elasticity of the elastic stretching complex. The replica part 6 is made of elastic soft foaming materials, such as foam, latex, etc., which can be elastically compressed and deformed, and can automatically elastically restore the shape after the compression force disappears.

The closure set 5 includes a block 51 for sealing the air intake head 32 to be airtightly plugged on the air intake head 32, and a block 51 for screwing and fixing to the air intake head 32 to limit the block 51. Located on the cover 52 of the air inlet head 32 .

As shown in Figures 3, 4, and 5, when the object 900 is to be inflated by the inflating device of the present invention, the closed sleeve 5 can be detached from the air intake head 32, so that the air chamber 310 of the soft bag 31 Connect with the outside world. Then, by stepping down on the top wall 313 of the soft bag 31, the air chamber 310 of the soft bag 31 is forced to be compressed and deformed, and the air in the air chamber 310 is pushed toward the non-return air outlet member 33, and the The non-return air outlet part 33 changes from the closed state to the open state, that is, the plastic sheet 331 is opened to become the exhaust passage 330, and the object 900 is inflated, and at the same time, the spring 4 will be compressed. The complexing elastic force is stored, and the complexing part 6 will also elastically deform together with the soft capsule 31 to store the complexing elastic force.

When the power to press the soft bag 31 disappears, the complex elastic force of the spring 4 will start to support the top wall 313 of the soft bag 31 upwards, and by moving the top wall 313 upwards, the twisted shape will be pulled. The deformed ring wall 312 expands upwards to support the complex shape. At the same time, the complex elastic force of the complex part 6 fixed on the ring wall 312 will also act on the ring wall 312 respectively, which can assist the position of the ring wall 312 to expand the complex shape. shape, the simultaneous action of the double elastic force can speed up the reshaping speed of the soft capsule 31 .

In addition, when the soft bag 31 is compressed and deformed to the limit, and no gas is squeezed into the non-return air outlet 33 to break the plastic sheet 331, since the anti-return air outlet 33 itself is flat, the plastic sheet 331 will automatically stack up and down together. Then, while the soft bag 31 is propped back into shape, the air chamber 310 will gradually expand outwards and generate a negative pressure suction relative to the non-return air outlet part 33, and the negative pressure suction will drive the plastic sheet 331 to face each other. Airtightly fit and close, so that the non-return air outlet part 33 returns to the closed state, so that the gas in the object 900 cannot flow back into the soft bag 31 through the anti-return air outlet part 33, thereby achieving the anti-reverse effect.

In addition, when the inflating device is to be accommodated, the air inlet head 32 can be closed with the sealing sleeve 5 when the soft bag 31 is compressed to prevent gas from re-entering the air chamber 310, so that the air bag can The mechanism 3 is maintained in a compressed state with a small volume, and the negative pressure suction generated in the soft bag 31 will drive the non-return air outlet element 33 to maintain an airtight sealing state. However, during implementation, the accommodating manner of the inflating device is not limited thereto.

In this embodiment, a plurality of compound parts 6 are arranged at intervals around the ring wall 312 , but in practice, only one compound part 6 can achieve the effect of assisting the ring wall 312 to reshape.

In summary, by setting the structural design of the soft elastic complex part 6 on the ring wall 312, the simultaneous action of the dual forces of the complex elastic force of the spring 4 and the complex elastic force of the complex part 6 can be used to improve the driving force. The active force of the reshaping of the soft bag 31 can relatively accelerate the reshaping speed of the soft bag 31 without increasing the wire diameter of the spring 4, so that the inflating speed of the inflating device of the present utility model is relatively improved. The structural design of the non-return air outlet part 33 can easily achieve the purpose of non-return through the air-tight fit of the upper and lower sides of the two plastic sheets 331. It is not necessary to use the general non-return air nozzle, which can make the structure of the pumping device more compact. Simple, and help to further reduce manufacturing cost and weight, quite convenient and practical.
