Abstract
The utility model provides a kind of vacuum generating device, and it comprises vacuum generator tube and outlet pipe, and described vacuum generator tube and described outlet pipe are through being threaded; The inwall of described vacuum generator tube has a positive round frustum, the contiguous described positive round frustum of screw terminal of described outlet pipe; The inwall of described vacuum generator tube, the outer wall of described outlet pipe screw terminal and described positive round frustum surround a hyperbaric chamber.The beneficial effects of the utility model are: efficiency is high, noise is low, and meanwhile, this vacuum generating device small volume and less weight, cost are also not high.Further, locking nut is set, makes to vacuumize dynamics adjustable.
Description
Technical field
The utility model relates to vacuum pumping technology field, particularly a kind of vacuum generating device.
Background technique
Existing vacuum pumping device, be a straight tube and be embedded on straight pipe wall enter tracheae, this enters one end towards straight tube, air outlet of tracheae, then, when ventilating, namely form region of no pressure at the other end of straight tube.
This vacuum pumping device efficiency is low, noise is high.
Model utility content
In order to solve above-mentioned existing technical problem, the utility model provides a kind of vacuum generating device, and its efficiency is high, noise is low, and meanwhile, this vacuum generating device small volume and less weight, cost are also not high.
The utility model solves above-mentioned existing technical problem, and provide a kind of vacuum generating device, it comprises vacuum generator tube and outlet pipe, and described vacuum generator tube and described outlet pipe are through being threaded; The inwall of described vacuum generator tube has a positive round frustum, the contiguous described positive round frustum of screw terminal of described outlet pipe; The inwall of described vacuum generator tube, the outer wall of described outlet pipe screw terminal and described positive round frustum surround a hyperbaric chamber.
The utility model further improves as described below.
Just pore is set into the described vacuum tube wall of described hyperbaric chamber.
Also comprise a locking nut, described locking nut is threadedly connected to described outlet pipe, and described locking nut is connected to the connecting end of described vacuum generator tube.
Compared to prior art, the beneficial effects of the utility model are: efficiency is high, noise is low, and meanwhile, this vacuum generating device small volume and less weight, cost are also not high.Further, locking nut is set, makes to vacuumize dynamics adjustable.
Accompanying drawing explanation
Fig. 1 is the generalized section of the utility model vacuum generating device.
Vacuum generator tube 1 | Connecting end 11 |
Blowhole air intake 12 | Positive round frustum 13 |
Outlet pipe 2 | Screw terminal 21 |
Hyperbaric chamber 3 |
Embodiment
To illustrate below in conjunction with accompanying drawing and embodiment further illustrates the utility model.
As shown in Figure 1, a kind of vacuum generating device, it comprises vacuum generator tube 1 and outlet pipe 2, and vacuum generator tube 1 and outlet pipe 2 are through being threaded; The inwall of the utility model vacuum generator tube 1 has a positive round frustum 13, namely Z-shaped vertically, screw terminal 21 this positive round frustum 13 contiguous of outlet pipe 2, has gap, so that gas passes through between the surface of positive round frustum 13 and the end face of outlet pipe 2 screw terminal 21.The inwall of vacuum generator tube 1, the outer wall of outlet pipe 2 screw terminal 21 and positive round frustum 13 surround a hyperbaric chamber 3, the gas entered in this hyperbaric chamber 3 forms annular airflow, when flowing through positive round frustum 13, diverted flow is in outlet pipe 2, enter air-flow in outlet pipe 2 relatively milder, without whirlpool, in vacuum generator tube 1, namely produce lowpressure like this, form vacuum state.
The utility model is just setting into pore 12 to the vacuum tube wall of hyperbaric chamber 3, so that gas enters in hyperbaric chamber 3, other mode passing into gas that related domain also can be adopted to know know makes gas enter in hyperbaric chamber 3.
The utility model also comprises a locking nut, and locking nut is threadedly connected to outlet pipe 2, and locking nut is connected to the connecting end 11 of vacuum generator tube 1, and this locking nut can regulate the flow of air-flow, thus the dynamics that control vacuumizes.
The utility model efficiency is high, noise is low, and meanwhile, this vacuum generating device small volume and less weight, cost are also not high.Further, locking nut is set, makes to vacuumize dynamics adjustable.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
