The top wall is equipped with the power in detecting chamber 32, and two resistance tops respectively with the negative pole of power and positive pole electric connection, and two resistances realize electric connection through current-conducting plate 62.

Since the conductive plate 62 has a conductivity that is much greater than the conductivity of the liquid in the tank 3, there will be a short circuit for the liquid by the conductive plate 62, and thus no current will pass through the liquid.

3 bottom fixedly connected with hydrojet 4 of liquid reserve tank, 4 bottoms in hydrojet are equipped with a plurality of evenly distributed's shower nozzle 5.

An air outlet 11 is arranged on the airship body 1, and a control mechanism 7 associated with the liquid level detection mechanism 6 is arranged at the air outlet 11.

The control mechanism 7 is composed of a fixed ring 71, a telescopic cylinder 72, and a seal plate 73.

The fixing ring 71 is fixedly arranged on the side wall of the air outlet 11, the telescopic cylinder 72 is fixedly connected with the side wall of one side of the air outlet 11, which is far away from the airship body 1, the other end of the telescopic cylinder 72 is fixedly connected with the sealing plate 73, and the sealing plate 73 and the fixing ring 71 are sealed and abutted through the telescopic cylinder 72.

An electromagnet 731 is arranged in the sealing plate 73, the fixing ring 71 is made of ferromagnetic material, and the power of the electromagnet 731 is controlled by the contact position of the conductive plate 62 and the pair of conductive resistors 64.

The electromagnet 731 is connected in series with the resistor, so that the power of the electromagnet 731 is smaller when the resistance value of the resistor connected into the circuit is larger, namely, the power of the electromagnet 731 is smaller when the height of the liquid level is lower.

The telescopic cylinder 72 is composed of a moving column 721, a fixed column 722 and a spring 723, the moving column 721 is fixedly connected with the sealing plate 73, the fixed column 722 is fixedly connected with the side wall of the air outlet 11, a sliding groove 724 is arranged in the fixed column 722, the moving column 721 is slidably connected inside the sliding groove 724, one end of the spring 723 is fixedly connected with the moving column 721, and the other end of the spring 723 is fixedly connected with the inner wall of the sliding groove 724.

The operating principle of the present invention will now be described as follows:

when this device spouts the medicine, the liquid in the liquid reserve tank 3 will gradual reduction, and then realize that the whole weight of device will gradual reduction.

Because the communicating vessel principle, liquid level in detection chamber 32 and the liquid storage chamber 31 will be flat setting under no exogenic action, and be equipped with elements such as floating plate 61 in the detection chamber 32, so liquid level in the detection chamber 32 will be a little less than the liquid level height of liquid storage chamber 31, but when liquid level changes in the liquid storage chamber 31, the liquid level in the detection chamber 32 will change together this moment, and then realize this moment will make floating plate 61 change along with detecting the interior liquid level change of chamber 32.

In the process that the liquid medicine in liquid reserve tank 3 reduces, the floating plate 61 will reduce along with the reduction of liquid level in the liquid reserve chamber 31, and then realize this moment will the current conducting plate 62 will move down gradually, and then realize this moment will make the resistance that the resistance inserts the resistance in the circuit crescent, and then realize this moment that the power with the electro-magnet 731 of resistance series connection will reduce gradually.

When the power of the electromagnet 731 is gradually reduced, because the interior of the airship body 1 is filled with high-pressure gas, the pressure of the gas in the airship body 1 on the sealing plate 73 is greater than the attractive force between the telescopic cylinder 72 and the electromagnet 731 and the fixing ring 71, and the sealing plate 73 moves away from the fixing ring 71 under the action of the gas pressure.

At this time, the gas in the airship body 1 will leak from between the fixing ring 71 and the sealing plate 73, the gas pressure in the airship body 1 will be reduced after the gas is lost, and when the extrusion force of the gas pressure on the sealing plate 73 is smaller than the sum of the thrust of the telescopic cylinder 72 on the sealing plate 73 and the attraction force between the electromagnet 731 and the fixing ring 71, the sealing plate 73 will abut against the fixing ring 71 again, and the fixing ring 71 and the sealing plate 73 will close the gas outlet 11 again.

The in-process can realize reducing the gas of air ship main part 1, and then reduces the volume of air ship main part 1, and then reduces the buoyancy of air ship main part 1, and then the realization device can be along with the reduction of the liquid in the liquid reserve tank 3 realization self buoyancy, and then the realization device is located certain height all the time, and then the realization in-process spouts the height of medicine must, and then the realization process has better medicine effect of spouting all the time, and then ensures the homogeneity of in-process medicine spout.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
