Description
Technical field
The utility model designs the field of medical instrument technology more particularly to a kind of secondary vacuum generator.
Background technology
It needs repeatedly to carry out gas displacement in large-scale sterilizing device sterilization process and reaches sterilization effect, and gas displacement needs go out
Bacterium device reaches certain vacuum degree, and existing gas vacuum generator has higher air source requirement on the market, needs with corresponding
Auxiliary facility is not suitable for sterilizer so that sterilizer can not rapidly and efficiently reach required vacuum environment when in use.
Utility model content
The utility model be directed to deficiency in the prior art, provide it is a kind of can be rapidly and efficiently make required for reaching sterilizer
Vacuum environment secondary vacuum generator.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of secondary vacuum
Generator, including generator body are provided with the communication groove of mutual unicom, the first vacuum chamber, second in the generator body
Vacuum chamber is provided with switching device between communication groove and the second vacuum chamber, is located at the first vacuum chamber and the second vacuum chamber barrier
Be provided with the level-one diffusing opening with two vacuum chamber unicom, the rear and front end of the generator body be respectively arranged with jet port and
It is provided with one on two level diffusing opening, with the generator body of jet port, level-one diffusing opening and the perpendicular direction of two level diffusing opening
Grade suction inlet and main vacuum port.
In said program, it is preferred that the switching device is cut-off diaphragm.
In said program, it is preferred that the opening of level-one suction inlet is open less than main vacuum port.
In said program, it is preferred that the opening of level-one diffusing opening is open less than two level diffusing opening.
Compared with prior art, the utility model has the advantages that：It is true using two level by using above structure
Hollow structure improves the working efficiency of sterilizer to reach the dual purpose of quickly suction and high vacuum.
Description of the drawings
Fig. 1, the utility model structure diagram.
A-A sectional views in Fig. 2, Fig. 1.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to Fig. 1 to Fig. 2, a kind of secondary vacuum generator, including generator body 1, the interior setting of the generator body
There are the communication groove 11 of mutual unicom, the first vacuum chamber 12, the second vacuum chamber 13, is arranged between communication groove 11 and the second vacuum chamber 13
There is switching device 2, the level-one with two vacuum chamber unicom is provided at 13 barrier of the first vacuum chamber 12 and the second vacuum chamber
The rear and front end of diffusing opening 3, the generator body 1 is respectively arranged with jet port 4 and two level diffusing opening 5, with jet port 4, one
It is provided with level-one suction inlet 6 and main vacuum port on grade diffusing opening 3 and the generator body 1 in 5 perpendicular direction of two level diffusing opening
7, the switching device 2 is cut-off diaphragm, and the opening of level-one suction inlet 6 is open less than main vacuum port 7, and level-one diffusing opening 3 is opened
Mouth is less than two level diffusing opening 5 and is open.
The energy is provided by outer water pump, flow is made to accelerate, flows at the jet port 4 of generator body 1, makes flow again
Accelerate, the pressure near jet port 4 drastically becomes smaller at this time, and to generate pressure compensation in main vacuum port 7, extraneous medium is sucked
Reach pressure balance to generate vacuum, flow still there are many energy after flowing through jet port 4 and level-one diffusing opening 3, at this time level-one
Diffusing opening 3 can be converted into jet port, by water flow jet into end secondary diffusing opening 5, achieve the effect that water energy two level utilizes.
4 suction force of jet port is strong, and flow is smaller, and the jet port suction force that level-one diffusing opening 3 converts is small, and flow is big, works as quilt
Suction chamber vacuum degree be higher than the second 13 vacuum degree of vacuum chamber when, the second vacuum chamber 13 is automatically closed, only stay the first vacuum chamber 12 after
Continuous work, to reach the dual purpose of quickly suction and high vacuum, product can effectively adapt to high temperature ring using all-metal manufacture
Border.It is highly suitable for the high-temperature work environment of sterilizer.
The scope of protection of the utility model includes but not limited to embodiment of above, and the scope of protection of the utility model is to weigh
Subject to sharp claim, any replacement being readily apparent that those skilled in the art that this technology is made, deformation, improvement are each fallen within
The scope of protection of the utility model.
