Abstract

The utility model discloses a leak-free automatic opening and closing device comprising a tubular suction nozzle head body. A resilient sealing disc is disposed in the middle of a suction nozzle head inner hole. A thin annular edge around the sealing disc is connected with the side wall of the inner chamber of the body. A liquid outlet cut is disposed in the middle part of the sealing disc. The outside of the suction nozzle head body is connected with a small circular pipe through a rib strip, and a gas supply cut is disposed in the bottom of the small circular pipe. The device can be disposed in the liquid outlet opening of the container, when the body is in the suction movement, and because the annular edge of the sealing disc is the thin annular disc, the cut in the middle part of the sealing disc can be opened automatically under the action of the suction, and the liquid in the container can flow out through the cut and the liquid outlet hole of the body. When the liquid in the container is sucked out, the atmospheric pressure can press the cut in the bottom of the small circular pipe to open and then the gas can be supplied into the container in order to balance the pressure. When the container is overturned, the liquid in the container can not flow out, because the sealing disc is closed, and the liquid in the container can not be polluted.

Description

A kind of automatically opening and closing device capable of preventing from leakage in overturning

Technical field

The utility model relates to container, is specifically related to a kind of automatically opening and closing device capable of preventing from leakage in overturning that is used on the container.

Background technology

In the prior art, when needs are sucked liquid in the container, all be directly to open container cover to suck usually, when not inhaling, lid must be built the liquid that can not that could guarantee in the container and flow out automatically, particularly when the container overturning; When needs are sucked again, reopening container cover again just can suck, there is following defective: after container is overturned, liquid in the container can flow out automatically, airborne bacterium also enters in the container easily, in sucking process, can not in time mend into air, make in sucking process afterwards harder.

The utility model content

The purpose of this utility model is, a kind of automatically opening and closing device capable of preventing from leakage in overturning is provided, and uses this automatically opening and closing device capable of preventing from leakage in overturning, also can not spill when container is overturned, and can carry out tonifying Qi in the trend container in sucking process.

The technical scheme that the utility model provides is as follows: construct a kind of automatically opening and closing device capable of preventing from leakage in overturning, the suction nozzle head body that comprises a tubulose, the middle part of suction nozzle head endoporus is provided with an elastic seal dish, the periphery of described seal disc has a thin type ring limit and is connected with the sidewall of described chamber body, have the fluid designated port at the middle part of seal disc, the outside at described suction nozzle head body is connected with a little pipe by a rib, and the bottom of little pipe has the tonifying Qi designated port.

In above-mentioned automatically opening and closing device capable of preventing from leakage in overturning, the thickness at described seal disc middle part is greater than the thickness on its thin type ring limit.

In above-mentioned automatically opening and closing device capable of preventing from leakage in overturning, the bottom of described little pipe is the taper of stretching out downwards.

The utlity model has following advantage: this device is installed in the liquid outlet of container, when body is moved in suction, because the ring limit of seal disc is the thin type ring limit, seal disc can upwards be dug under the effect of suction, the designated port at seal disc middle part can be opened under the effect of suction automatically, liquid in the container can also flow out by the fluid hole of body from designated port, after the liquid sucking-off in the container, pressure in the bottle can reduce, bar pressure can press off designated port tonifying Qi in container of roundlet pipe bottom, with equilibrium of pressure, when suction disappeared, two designated ports all can SELF CL, when the container overturning, because seal disc is closed, the liquid that can not in the container flows out, and has guaranteed that also liquid in containers can not polluted.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of automatically opening and closing device capable of preventing from leakage in overturning is provided, the suction nozzle head body 1 that comprises a tubulose, the middle part of suction nozzle head body 1 endoporus is provided with an elastic seal dish 024, the periphery of described seal disc 024 has a thin type ring limit 025 and is connected with the sidewall of described suction nozzle head body 1 inner chamber, have fluid designated port 111 at the middle part of seal disc 024, the outside at described suction nozzle head body 1 is connected with a roundlet pipe 020 by a rib, and the bottom of roundlet pipe 020 has tonifying Qi designated port 111.

In above-mentioned automatically opening and closing device capable of preventing from leakage in overturning, the thickness at described seal disc 024 middle part is greater than the thickness on its thin type ring limit 025.

In above-mentioned automatically opening and closing device capable of preventing from leakage in overturning, the bottom 021 of described roundlet pipe 020 is the taper of stretching out downwards.

This device is installed in the liquid outlet of container, when body 1 is moved in suction, because the ring limit 025 of seal disc 024 is the thin type ring limit, seal disc 024 can upwards be dug under the effect of suction, as shown in Figure 4, the designated port at seal disc 024 middle part can be opened under the effect of suction automatically, liquid in the container can also flow out by the fluid hole of body 1 from designated port 111, and after the liquid sucking-off in the container, the pressure in the bottle can reduce, bar pressure can press off designated port 111 tonifying Qi in container of roundlet pipe 020 bottom, with equilibrium of pressure, when suction disappeared, seal disc 024 resetted downwards under the elastic force effect, as shown in Figure 3, two designated ports 111 all can SELF CL, when the container overturning, because seal disc 024 is closed, liquid that can not in the container flows out, and has guaranteed that liquid in containers can not polluted.
