Specific embodiment
With reference to the accompanying drawing and specific example, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Bright the utility model rather than limitation the scope of the utility model, after having read the utility model, those skilled in the art
Member falls within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
Referring to FIG. 1, present embodiment discloses a kind of automatic negative-pressure drainage device, including negative pressure generator, negative pressure occur
Device includes liquid-collecting bottle and the generating bottle below liquid-collecting bottle.
The upper end of liquid-collecting bottle is provided with liquid-entering hole, and liquid-entering hole is communicated with hose, and flow valve is configured on hose, with control
The rate of influx of liquid.
Referring to FIG. 2, the lower end of liquid-collecting bottle is a tip conical flask directed downwardly, offered in the tip portion of conical flask
Middle port.Conical flask part is down protruded into the opening of generating bottle.So, fluid, such as water are filled in liquid-collecting bottle.When water passes through
When middle port flows into generating bottle from liquid-collecting bottle, the gas gross in liquid-collecting bottle is constant and the increase that takes up space, generation negative pressure.This
When, turn-on flow rate valve makes the drain of human body enter liquid-collecting bottle collection through hose.
It is connected by screw thread in vertical direction between the liquid-collecting bottle and generating bottle of the present embodiment negative pressure generator；Specifically,
The generating bottle periphery of the negative pressure generator of the present embodiment is arranged with annular outer cover, passes through between annular outer cover and the opening of generating bottle
It is threadedly coupled, to be formed for collecting the cavity for falling fluid from liquid-collecting bottle, outside annular between annular outer cover and generating bottle
Gas vent is offered on shell shell, to guarantee that cavity is connected to outside.
Further, Flow restrictions are configured in the generating bottle of the present embodiment, current-limiting apparatus includes conical sealing plug, taper
Block head is fixed on the bottom of generating bottle, and tip upward and partially protrudes into middle port.The annular outer cover and hair of the present embodiment
When raw bottle is connected through a screw thread, conical sealing plug is partially protruded into middle port, blocks middle port, so prevent fluid from
It is fallen in conical flask, realizes the control to negative pressure drainage.
Certainly, when opposed annular shell screws generating bottle, conical sealing plug does not seal the present embodiment to middle port
Stifled, the gap enabled a fluid between conical sealing plug and middle port is fallen into generating bottle.So, different degrees of opposite
When annular outer cover screws generating bottle, the gap size between conical sealing plug and middle port can be expanded or shunk, and then control
Fluid falls into the rate of generating bottle.
In summary technical solution, the automatic negative-pressure drainage device of the present embodiment when in use, be first shut off flow valve and
Guarantee closure of the conical sealing plug to middle port, hose be connected to drainage portion, rotates generating bottle relative to liquid-collecting bottle,
Make to generate gap between conical sealing plug and middle port.At this point, the gas gross being located in liquid-collecting bottle is constant and shared volume increases
Greatly, then negative pressure is generated.Flow valve is opened again, carries out drainage operation using the negative pressure that liquid-collecting bottle kind generates.
In addition Fig. 3 and Fig. 4 are please referred to, the inner wall of the present embodiment generating bottle is equipped with annular groove and is connected to groove
Two notches, there are two elastic support, two elastic supports are connected with limit corresponding with notch for the bottom connection of conical sealing plug
Position block, limited block along notch enter annular groove after conical sealing plug fixed in vertical direction in opposite generating bottle.So, this reality
The current-limiting apparatus for applying example can dismount, can in order to when the particulate matters such as such as grit damage conical sealing plug friction
The conical sealing plug more renewed guarantees smoothly falling for fluid.
In addition, the liquid-collecting bottle of the present embodiment is internally provided with elastic film, it is connected to hose for separating liquid-collecting bottle
Fluid is filled in the inner space of conical flask in the inner space of end spaces and conical flask.So, the fluid drainage in conical flask
In the process, elastic film partially can be used to compensate the volume that liquid is excluded in conical flask to lower recess；Meanwhile it will increase liquid-collecting bottle
The upper end space volume being connected to hose, and then negative pressure is formed, realize negative pressure drainage.So, the present embodiment passes through above-mentioned technology
Scheme can will draw liquid and fluid isolation by elastic film, and prevent from drawing liquid and fluid while realizing negative pressure drainage
Liquid mixing, convenient for the recycling of the two.
