[0002] Pesticides are often used in agriculture. The purchased pesticides are often high-concentration liquids. Before use, they need to be mixed with other solvents and diluted in a certain proportion before they can be used. As we all know, organophosphorus insecticides It is highly volatile and toxic. If you open the cap and pour it directly into the blending ratio, the bottle cap will remain open during the blending process, and the volatile medicinal liquid is easily inhaled by the human bo...

Abstract

Provided is a hand pressing type liquid medicine separator. The hand pressing type liquid medicine separator is provided with a bottle cap. The bottle cap is matched with a liquid medicine bottle opening in a rotating fit mode, the bottle cap is provided with a vertical guide pipe in a penetrating mode, a liquid sucker is connected to the lower end of the guide pipe, and the upper end of the guide pipe penetrates through a lower bag wall of the hand pressing type air bag and then is communicated with a liquid outlet pipe penetrating through the side bag wall penetrating through the hand pressing type air bag. The hand pressing type liquid medicine separator is simple in structure and low in cost, due to the hand pressing type mode, liquid medicine can be separated and taken out from a liquid medicine bottle, potential safety hazards such as liquid medicine pouring are avoided, and the hand pressing type liquid medicine separator has the advantages that the liquid extracting and separating operation is safe and convenient, and the overall practicability of the separator is high.

Example Embodiment

[0015] Attached below Figure 1-2 One embodiment of the present invention is described.

[0016] The hand-pressed medicinal liquid separator has a bottle cap 4, which is screwed and connected to the medicinal liquid bottle mouth, and the bottle cap 4 is made of polyethylene or polypropylene, and its diameter is 28mm ~38mm, the bottle cap 4 of this structural material, first of all, the diameter of the bottle cap 4 matches the bottle mouth size of the conventional liquid medicine bottle on the market, which is convenient for quick screw connection with liquid medicine bottles of different diameters on the market; When it is connected with the mouth of the liquid medicine, the polyethylene or polypropylene material has the characteristics of low price, safety and environmental protection, and excellent flexibility and physical and mechanical strength.

[0017] The upper end face passing through the bottle cap 4 is provided with a vertical conduit 3, the conduit 3 is a connector, and the lower end of the conduit 3 is used to connect different lengths of liquid-taking pipettes 5, different lengths of liquid-taking pipettes 5 and different heights of medicinal liquid The upper end of the catheter 3 passes through the end face of the lower bag wall of the hand-pressure airbag 1 and then connects to the lower end of the tee tube. The upper end of the tee tube is reserved for overflow prevention. The nozzle is communicated with the liquid outlet pipe 2 passing through the side wall of the hand-pressure airbag 1. Specifically, the liquid outlet pipe 2 is provided at the lower part of the side wall of the hand-pressure airbag 1, so as to shorten the flow of medicinal liquid through each guide. The total stroke of the pipe is conducive to rapid liquid discharge. In addition, in order to avoid guiding the suctioned liquid medicine into the container, the pipe length of the liquid discharge pipe 2 is at least 20 mm.

[0018] Further, in order to ensure the tightness of the device, sealing rings are respectively provided at the connection between the catheter 3 and the bottle cap 4 and the bag wall of the hand-pressure airbag 1; the liquid outlet pipe 2 and the bag wall of the hand-pressure airbag 1 There is also a sealing ring at the connection.

[0019] Usage principle: before suction, firstly connect the bottle cap 4 of the present invention to the mouth of the medicinal liquid, then squeeze the hand-pressure airbag 1 downward with one hand, the hand-pressure airbag 1 is compressed, and then release the hand During the process of restoring the volume of the pressure type airbag 1 and the manual pressure type airbag 1 to the original volume, the liquid medicine in the liquid medicine bottle is sucked into the liquid suction pipe 5 due to the negative pressure in the bag, and then flows through the catheter 3, After the liquid outlet pipe 2, it is finally separated and taken out from the nozzle of the liquid outlet pipe 2.

[0020] In the whole liquid taking operation, firstly, the pouring of the liquid medicine bottle is avoided, so the pouring of the liquid medicine is avoided. Furthermore, the direct contact with the medicinal liquid bottle by the hand is avoided, and the safety is ensured. Furthermore, the bottle mouth of the medicinal liquid is in a closed state to avoid the volatilization of the medicinal liquid, so the present invention has the characteristics of simple overall structure, easy operation, safe use and strong practicability.

[0021] The above-mentioned embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made based on the contents described in the claims of the present invention shall be included within the scope of the claims of the present invention. .
