Abstract

The utility model relates to a novel liquid discharging device which can realize self-press liquid discharge through a negative-pressure generator and can be used for altering the mode of the traditional suction liquid by a mouth to realize automatic liquid discharge. The utility model is composed of a hose, a negative-pressure generator and stop valves. The negative-pressure generator is operated to generate negative-pressure to suck liquid into the hose, and the self-press liquid discharge is accomplished by the liquid level differences of both ends of the hose. Thus, the utility model makes the liquid discharging process convenient, and has no damage to the health of a human body. The utility model can be used for filling water in a fish bowl or filling oil in a machine or discharging oil from the machine.

Description

Self-press liquid discharging device

The utility model relates to a kind of fish jar that is used for and changes water, and machine is annotated and to be drained the oil and the self-pressing type pumping equipment of similar applications.

Fish jar is breeded fish and need often be changed water, and fish jar is bigger, and great majority do not have the dewatering orifice again, fish jar can not be inverted or dip with other containers when draining addle.Addressing this problem common way is with a flexible pipe, at the bottom of the insertion fish jar internal water, the other end manually with mouth with bilge suction pipe, place rapidly then in the lower container, let out from pressure by water.

Some places are subjected to condition restriction, usually adopt above-mentioned way toward interior oiling water filling of machine or oil extraction water vent.With in the foul suction inlet, very unhygienic, especially oils is harmful unavoidably for this way.

The purpose of this utility model is that a kind of self-pressing type pumping equipment will be provided, and it can not suck pipe by mouth with liquid, realizes draining by the pressure reduction of liquid.

The purpose of this utility model has been achieved in that a flexible pipe, connects a negative pressure generator and a stop valve at the one end.One end of flexible pipe is inserted in the liquid of desire drainage, close stop valve, handle negative pressure generator and make it to produce negative pressure, then liquid charges in the flexible pipe under the atmospheric pressure effect, negative pressure generator is placed lower, open stop valve, then liquid relies on the liquid level difference at pipe two ends to realize letting out from pressure.

The utility model has replaced the same function of mouth because of using a negative pressure generator, so health is not had any infringement; While is installed a stop valve at an end of negative pressure generator, and when needs were interrupted drainage, the operation stop valve was closed or opened and can realize, and needn't inhale or operate the action of negative pressure generator by the repetitive manual mouth, thereby uses convenient.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the profile according to the self-pressing type pumping equipment that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This device comprises a negative pressure generator (4) that is become by the elastic hollow system of both ends open, and the one end connects with a flexible pipe (2) with one two pass joint (3), and the other end connects with a stop valve (5) and a flexible pipe (6).

Below the liquid level with the insertion container (1) of flexible pipe (2), negative pressure generator (4) places the following place of liquid level outside the container (1).Pinch negative pressure generator (4) with hand, its inner air is discharged, close stop valve (5) then, decontrol negative pressure generator (4), make and wherein produce negative pressure, then the liquid in the container (1) is full of flexible pipe (2) under the atmospheric pressure effect, opens stop valve (5), and the liquid in the container (1) is by flowing in the lower container (7) from pressure.When container (7) when filling with, close stop valve (5) liquid and stop to flow, open stop valve (5) behind the container to be turned (7) again, then liquid recovers mobile again.

This device can also be linked together negative pressure generator, flexible pipe and stop valve and be formed by a three-way connection, and negative pressure generator wherein is the elastic hollow body of one one end opening, and operating process is the same fully.

Claims

1, be used for fish jar and change water or machine and annotate the self-pressing type pumping equipment of draining the oil, this device has a flexible pipe, it is characterized in that a negative pressure generator and the stop valve sent out of a termination at flexible pipe.

2, pumping equipment according to claim 1 is characterized in that negative pressure generator is the elastic hollow body of both ends open when flexible pipe, negative pressure generator and stop valve coupled in series successively.

3, pumping equipment according to claim 1 is characterized in that as a three-way connection flexible pipe, negative pressure generator and stop valve being associated in a time-out, and negative pressure generator is the elastic hollow body of an end opening, perhaps small-sized plunger or piston cylinder.
