Abstract
The invention relates to a pneumatic vacuum generator. The pneumatic vacuum generator is characterized by comprising an air outlet, a laval nozzle, a spray nozzle, a negative-pressure cavity, a vacuum port, a shell and an air inlet. According to the pneumatic vacuum generator, compressed air serves as power, the compressed air can enter the airflow spray nozzle, airflow flows out of the spray nozzle at a high speed, the air suction effect is achieved, and finally the compressed air and sucked air are discharged into the atmosphere through a receiver spray nozzle. The pneumatic vacuum generator with the design is simple in structure, low in manufacturing cost, small in absorption volume, short in response time, small in surface leakage amount and low in air consumption.
Description
Technical field
The present invention relates to a kind of vacuum equipment, particularly relate to a kind of air pressure vacuum generator.
Background technology
It is mechanical that air pressure vacuum generator is widely used in broadcast, communication, TV, radar, navigation, industrial automation, electronics, packaging, printing, the air pressure vacuum generator in the field such as plastics and robot needs various materials are adsorbed, carried, and is particularly suitable for absorption frangible, soft, thin non-ferric, nonmetallic materials or spheroidal object, what common air pressure vacuum generator adopted is that vacuum pump has motor to drive, and the energy consumption of generation is big, volume is big, Heavy Weight and need periodic maintenance.
In addition in application process, common air pressure vacuum generator is unstable due to rate of air sucked in required, and vacuum is difficult to control to, and during discontinuous operation, the time inaccuracy of interval, result in air pressure vacuum generator action not accurate.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of air pressure vacuum generator, it is possible to adopt compression air as power, it is provided that a kind of absorption volume is little, and response time is short, the air pressure vacuum generator that surface amount of leakage is little and air consumption is little.
For solving above-mentioned technical problem, the technical scheme is that
A kind of air pressure vacuum generator, its innovative point is in that: this air pressure vacuum generator includes air vent, Laval nozzle, nozzle, negative pressure cavity, vacuum port, housing and air intake；
Described air vent, nozzle, negative pressure cavity, Laval nozzle, air intake are successively set in air pressure vacuum generator housing, it is connected by nozzle between Laval nozzle with air vent, the vertical direction of this nozzle is provided with a vacuum port, negative pressure cavity is positioned at the seam of Laval nozzle and nozzle, and described air intake is connected to one end of Laval nozzle；
The T-shaped structure of described housing, this housing is positioned at the lateral surface of air vent, Laval nozzle, negative pressure cavity, vacuum port and air intake.
Further, described housing is positioned on the lateral surface at Laval nozzle place and is connected to an otic placode.
Further, described air vent, Laval nozzle, nozzle, vacuum port, air intake communicate.
It is an advantage of the current invention that: adopt compression air as power, this air pressure vacuum generator is by allowing compressed air into air current spray nozzle, air-flow is flowed out from nozzle at a high speed, produce gettering effect, finally make the air of compression air and suction be received device nozzle and enter air, the air pressure vacuum generator simple in construction of this design, low cost of manufacture, absorption volume is little, and response time is short, and surface amount of leakage is little and air consumption is little.
Air pressure vacuum generator is provided with otic placode can be fixed more efficiently by air pressure vacuum generator.

Detailed description of the invention
The following examples can make professional and technical personnel more fully understand the present invention, but does not therefore limit the present invention among described scope of embodiments.
A kind of air pressure vacuum generator as shown in Figure 1, its innovative point is in that: this air pressure vacuum generator includes air vent 1, Laval nozzle 2, nozzle 3, negative pressure cavity 4, vacuum port 5, housing 6 and air intake 7；
Air vent 1, nozzle 3, negative pressure cavity 4, Laval nozzle 2, air intake 7 are successively set in air pressure vacuum generator housing 6, it is connected by nozzle 3 between Laval nozzle 2 with air vent 1, the vertical direction of this nozzle 3 is provided with a vacuum port 5, negative pressure cavity 4 is positioned at the seam of Laval nozzle 2 and nozzle 3, and described air intake 7 is connected to one end of Laval nozzle 2；
The T-shaped structure of housing 6, this housing 6 is positioned at the lateral surface of air vent 7, Laval nozzle 2, negative pressure cavity 4, vacuum port 5 and air intake 7.
Housing 6 is positioned on the lateral surface at Laval nozzle 2 place and is connected to an otic placode 8, it is possible to quickly fixed by air pressure vacuum generator.
Air vent 1, Laval nozzle 2, nozzle 3, vacuum port 5, air intake 7 communicate.
The operation principle of this air pressure vacuum generator is: when the compression air intake 7 that is provided with from housing 6 of air enters after Lavalle sprays 2 pipes, air-flow sprays in Laval nozzle 2 at a high speed and enters in nozzle 3, sprayed by nozzle 3 again, the volume of negative pressure cavity 4 gas being provided with along with nozzle 3 and vacuum port 5 middle constantly expands, produce underbalance effect simultaneously, forming vacuum between negative pressure cavity 4 and vacuum port 5, compression air enters air by air vent 7.
Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention.Claimed scope is defined by appending claims and equivalent thereof.
