Embodiment

Seeing also Fig. 1 to Fig. 4, is the selected example structure of the utility model shown in the figure.

The improved device for vacuum generation of the utility model as shown in Figure 1, comprising: a body 1 and a pedestal 2, wherein:

This body 1 inboard has a vacuum forming chamber 11, this vacuum forming chamber 11 connects several vertically perforation 12, correspondence is respectively bored a hole and 12 is respectively equipped with a groove 13 in body 1 outside, ccontaining for a shock absorber 14, and body 1 outside end face is provided with the exhaust tube 15 of this vacuum forming chamber 11 of connection, to connect the system that a desire forms vacuum.

These pedestal 2 inboards are provided with the low pressure chamber 21 that several are made of withe 211 in regular turn, each withe 211 is respectively equipped with one and communicates and connect the injection pipe 22 of a tool nozzle, and be respectively equipped with in each low pressure chamber 21 top one with these body 1 perforation 12 through holes that communicate 212, make this through hole 212 and the perforation 12 of vacuum forming chamber 11 form a passage.These through hole 212 interior sidewall surface design for flexuose, form one first stop part 213 and one second stop part 214 in each through hole 212 respectively, and are ccontaining for a non-return assembly 3.This non-return assembly 3, in the present embodiment, having one is placed in the check spare 31 of first stop part 213 and a tool recess 321 and is placed in the fixed block 32 of second stop part 214, these fixed block 32 bottoms equidistantly extend upwardly establishes several supporting portions 322, for supporting this check spare 31, and fixed block 32 bottom outer rims are provided with several perforation 323, and supplied gas is passed through.This check spare 31 is convexly equipped with a protuberance 311 downwards, with with recess 321 driving fit mutually of this fixed block 32, and the mode that check spare 31 peripheries enlarge from top to bottom gradually forms the section of covering 312 of a umbrella, and 311 of this section of covering 312 and protuberances just can be shored for the supporting portion 322 of fixed block 32.And be provided with high-pressure air inlet 23 in these pedestal 2 outside end faces, be provided with an air outlet 24 away from an end of this high-pressure air inlet 23.

Make this pedestal 2 be positioned at a side of this body 1 by above-mentioned each member, and make this body 1 be the shape of combining closely, to form this device for vacuum generation with pedestal 2 by several lock firmwares.

During use, as shown in Figure 2, the system of this desire formation vacuum is connected in the exhaust tube 15 of body 1, start this device for vacuum generation, at this moment, pressurized gas can enter this pedestal 2 by this high-pressure air inlet 23, and pressurized gas are directly quick by behind each injection pipe 22 via the guiding of nozzle, by air outlet 2 gas discharged in pedestal 2.

And when pressurized gas are flowed through each injection pipe 22 fast, its high speed airflow will make each low pressure chamber 21 pressure inside pop-off, and being formed chamber 11 gas inside, vacuum forms a pumping action, making vacuum form chamber 11 interior gases is inhaled downwards, allow the gas can be by the perforation 323 of the section of covering 312 of this check spare 31 peripheries via fixed block 32, and continue at pressurized gas under the high flow rate effect of this low pressure chamber 21 of turnover, and be pumped in this low pressure chamber 21, allow vacuum forming chamber 11 form the vacuum shape, make the system that links to each other with body 1 exhaust tube 15 can produce vacuum effectiveness.

When pressurized gas pass through each injection pipe 22 and low pressure chamber 21 no longer fast, this vacuum forms chamber 11 and forms negative pressure, make the pressure of low pressure chamber 21 form chamber 11 greater than vacuum, the umbrella of this check spare 31 covered portion 312 and will be shored by the pressure of low pressure chamber 21 this moment, and with the through hole 212 inwalls shape that becomes to combine closely, and this check spare 31 pressurizeds are by pushing tow upwards, the perforation 12 that clogs vacuum forming chamber 11 can be upwards pushed up at the top of this check spare 31, whereby, to reach synchronously check effect completely.

As shown in Figure 3 because this check spare 31 has umbrella and covers portion 312, and this to cover portion 312 are above modes that down enlarge gradually, except that forming the guide function, also can have preferable check effect to gases in the vacuum forming chamber 11.

Secondly,, so, can make 2 of body 1 and pedestals have cushioning effect and preferable tightness, make 21 of this vacuum forming chamber 11 and low pressure chambers have good airtight effect in use because the utility model is provided with several shock absorbers 14 in the body perforation outside.

Certainly, still there are many examples in the utility model, therebetween the only variation on the details.See also Fig. 4, it is second embodiment of the present utility model, wherein, can form arranged outside several low pressure chambers 21A and several injection pipes 22A of chamber 11A in this vacuum, to increase the vacuum effectiveness that vacuum forms the chamber.
