Description
Technical field
The present invention relates to a kind of vacuum equipment, particularly relate to a kind of vacuum generator.
Background technology
Vacuum generator is widely used in broadcast, communication, TV, radar, navigation, industrial automation machinery, electronics, bag
Dress, printing, the vacuum generator in the field such as plastics and robot needs various materials are adsorbed, carried, is particularly suitable for
Adsorbing frangible, soft, thin non-ferric, nonmetallic materials or spheroidal object, common vacuum generator uses vacuum pump to be had
Motor drives, and the energy consumption of generation is big, and volume is big, Heavy Weight and need periodic maintenance.
In addition, in application process, common vacuum generator is unstable due to rate of air sucked in required, and vacuum is difficult to control to,
During discontinuous operation, the time inaccuracy of interval, result in vacuum generator action the most accurate.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of vacuum generator, it is possible to use compressed air as power,
Thering is provided one absorption volume little, response time is short, the 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 vacuum generator, its innovative point is: this vacuum generator includes air vent, Laval nozzle, nozzle, negative pressure
Chamber, vacuum port, housing and air intake；
Described air vent, nozzle, negative pressure cavity, Laval nozzle, air intake are successively set in vacuum generator housing, Lavalle
Being connected by nozzle between jet pipe with air vent, be provided with a vacuum port in the vertical direction of this nozzle, negative pressure cavity is positioned at and draws
Wa Er jet pipe and the seam of nozzle, described air intake is connected to one end of Laval nozzle；
The T-shaped structure of described housing, this housing is positioned at the outside of air vent, Laval nozzle, negative pressure cavity, vacuum port and air intake
Face.
Further, described housing is positioned on the lateral surface at Laval nozzle connection an otic placode.
Further, described air vent, Laval nozzle, nozzle, vacuum port, air intake communicate.
It is an advantage of the current invention that: using compressed air as power, this vacuum generator is by allowing compressed air into
Air current spray nozzle, flows out air-flow from nozzle at a high speed, produces gettering effect, finally makes the air of compressed air and suction be received device
Nozzle enters air, the vacuum generator simple in construction of this design, low cost of manufacture, and absorption volume is little, and response time is short, surface
Amount of leakage is little and air consumption is little.
It is provided with otic placode on vacuum generator can be fixed more efficiently by vacuum generator.

Detailed description of the invention
The following examples can make professional and technical personnel that the present invention is more fully understood, but the most therefore by this
Bright it is limited among described scope of embodiments.
A kind of vacuum generator as shown in Figure 1, its innovative point is: this vacuum generator includes air vent 1, Lavalle
Jet pipe 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 vacuum generator housing 6, Bearing score
It is connected by nozzle 3 between you jet pipe 2 and air vent 1, the vertical direction of this nozzle 3 is provided with a vacuum port 5, negative pressure cavity
4 seams being positioned at Laval nozzle 2 and nozzle 3, 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 air vent 7, Laval nozzle 2, negative pressure cavity 4, vacuum port 5 and air intake 7
Lateral surface.
Housing 6 is positioned on the lateral surface at Laval nozzle 2 connection an otic placode 8, it is possible to vacuum generator is quick
Fix.
Air vent 1, Laval nozzle 2, nozzle 3, vacuum port 5, air intake 7 communicate.
The operation principle of this vacuum generator is: when compressed air enters Lavalle spray from the air intake 7 that housing 6 is provided with
After 2 pipes, air-flow sprays in Laval nozzle 2 at a high speed and enters in nozzle 3, then is sprayed by nozzle 3, along with nozzle 3 and vacuum port 5
The volume of negative pressure cavity 4 gas that middle is provided with constantly expands, and produces underbalance effect, between negative pressure cavity 4 and vacuum port 5 simultaneously
Forming vacuum, compressed 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, above-described embodiment and explanation
The principle that the present invention is simply described described in book, without departing from the spirit and scope of the present invention, the present invention also has
Various changes and modifications, these changes and improvements both fall within scope of the claimed invention.Claimed scope
Defined by appending claims and equivalent thereof.
