Abstract
The invention discloses a vacuum generator, which includes an exhaust port, a receiver nozzle, an air chamber, an airflow nozzle, an inlet end, a vacuum port and a casing, wherein the exhaust port and the inlet end are arranged at the two ends of the casing respectively; the receiver nozzle is arranged on one side of the exhaust port; the airflow nozzle is arranged on one side of the inlet end; the air chamber is arranged on the outer side of the airflow nozzle; the vacuum port is arranged on one side of the air chamber; and a clearance is arranged between the receiver nozzle and the airflow nozzle. According to the vacuum generator provided by the invention, compressed air enters the airflow nozzle, and airflow flows out from the nozzle at a high speed, so that the air inhalation effect is realized, and finally the compressed air and inhaled air can be discharged to the atmosphere through the receiver nozzle; and the designed vacuum generator has the advantages of simple structure, low manufacturing cost, small adsorption volume, short response time as well as low surface leakage and air consumption.
Description
Technical field
The present invention relates to a kind of vacuum generator.
Background technique
Be widely used in machinery in broadcasting, communication, TV, radar, navigation, the industrial automation, electronics, packing, printing; The vacuum generator in field such as plastics and robot need adsorb, carry various materials, be particularly suitable for adsorbing frangible, softness, thin non-iron; Nonmetallic material or ball-type object, but in application process, because rate of air sucked in required is unstable; Degree of vacuum is difficult to control, and the time inaccuracy at intermittence during discontinuous operation has caused the vacuum generator action not accurate.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of existing technology, provide a kind of absorption volume little, the response time is short, the vacuum generator that surperficial amount of leakage is little and air consumption is little.
Technological scheme: in order to realize above purpose, a kind of vacuum generator of the present invention, it comprises relief opening, Receiver nozzle, air chamber; Air current spray nozzle, entry end, vacuum port and housing; The two ends of described housing are respectively equipped with relief opening and entry end; One side of described relief opening is provided with the Receiver nozzle, and a side of entry end is provided with air current spray nozzle, and the outside of air current spray nozzle is provided with air chamber; One side of described air chamber is provided with vacuum port, and the neutral position of described Receiver nozzle and air current spray nozzle is provided with the gap.
Described air chamber and vacuum port communicate
Beneficial effect: a kind of vacuum generator provided by the invention, get into air current spray nozzle through making pressurized air, air-flow is flowed out from nozzle at a high speed; Produce gettering effect, finally make pressurized air and inhaled air enter atmosphere through the receiver nozzle, the vacuum generator of this design is simple in structure; Low cost of manufacture; The absorption volume is little, and the response time is short, and surperficial amount of leakage is little and air consumption is little.
Description of drawings
Fig. 1 is a whole-cutaway view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention
Be illustrated in figure 1 as structural representation of the present invention, it comprises relief opening 1, Receiver nozzle 2, air chamber 4, air current spray nozzle 5, entry end 6, vacuum port 7 and housing 8.
The two ends of described housing 8 are respectively equipped with relief opening 1 and entry end 6; One side of described relief opening 1 is provided with Receiver nozzle 2; One side of entry end 6 is provided with air current spray nozzle 5; The outside of air current spray nozzle 5 is provided with air chamber 4, and a side of described air chamber 4 is provided with the vacuum port 7 that communicates with air chamber 4, and the neutral position of described Receiver nozzle 2 and air current spray nozzle 5 is provided with gap 3.
When the entry end 6 that is provided with from housing 8 when pressurized air gets into air current spray nozzles 5; Air-flow ejection in air current spray nozzle 5 at a high speed; The continuous expansion of gap 3 volumes that are provided with along with Receiver nozzle 2 and air current spray nozzle 5 neutral position; Produce rare effect simultaneously, form vacuum at air chamber 4 and vacuum port 7, pressurized air and inhaled air enter atmosphere through receiver nozzle 2 through relief opening 1.
The vacuum generator of this design is simple in structure, low cost of manufacture, and the absorption volume is little, and the response time is short, and surperficial amount of leakage is little and air consumption is little, so use occasion is extensive.
The foregoing description only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit is made according to the present invention or modification all should be encompassed within protection scope of the present invention.
