A semi-automatic mixing two-component spray can

technical field

The invention relates to a semi-automatic mixing two-component spray can.

Background technique

The spray can is a fairly common container, most of the general spray cans are filled with expansion liquid or gas, when in use, open the valve, the gas and liquid can be sprayed out. Currently commonly used spray cans are generally only filled with a liquid or a gas or a mixture of a liquid and a gas, such as a fire extinguisher, which mainly places the fire fighting fluid at the bottom of the tank, while the upper half of the tank is filled with High-pressure gas, showing the state of gas-liquid mixture. When the user presses the nozzle on the top of the tank to connect the space inside the tank with the atmosphere, since the pressure of the high-pressure gas in the tank is greater than the atmospheric pressure, the liquid at the bottom of the tank will be pushed out of the tank to produce a spray phenomenon, which can achieve fire extinguishing the goal of. Few spray cans are filled with two components of fluid at the same time, mainly because the two liquids are mixed for a long time, which is prone to chemical changes, resulting in uncontrollable quality and prone to danger. In many cases, the two components need to be stored separately when not in use, and only when in use are they mixed to undergo a chemical reaction, and then foam and expand, and the product can be directly applied. However, there is no spray can that can meet the above needs on the market.

In view of this, need to invent a kind of semi-automatic mixing two-component spray tank, to meet demand.

The diaphragm piercing mechanism can open the diaphragm to communicate with the two independent spaces when needed. The tank body is provided with a nozzle, and a valve switch is installed on the nozzle.

Further, the septum puncture mechanism includes a lift puncture assembly and a rotating assembly for rotating the lift puncture assembly.

Further, the lifting puncturing assembly includes a lifting rod, a support arm fixed on the lifting rod, and a piercing member fixed on the supporting arm;

The rotating assembly includes a central shaft, a cavity is provided in the central shaft, the lifting rod is located in the cavity, a compression spring is provided at the bottom of the cavity, and the side wall of the central shaft is opened for realizing A relief hole for the support arm to move up and down, and the central shaft forms a rotational fit with the tank body;

The central shaft forms a rotational fit with the diaphragm through a hinge.

Further, the piercing elements are blades or needles, and there are four piercing elements symmetrically arranged on both sides of the support rod.

Further, the cover body is clamped on the upper mouth of the tank body through a clip, and forms a rotational fit with the tank body, and the upper end of the central shaft is fixedly connected with the cover body.

Further, a through hole is opened on the cover body, and the lifting rod extends into the cavity of the central shaft through the through hole.

Further, a card slot is provided on the cover body, and a card block matching the card slot is provided on the lifting rod.

Further, the inner top wall of the tank is provided with a pressure warning device.

Further, the spray head is a flat and wide spray head.

Compared with prior art, the beneficial effect that the present invention obtains is as follows:

The semi-automatic mixing two-component spray tank provided by the present invention can package the two components separately, and can also puncture the diaphragm according to the needs to realize the mixing of the two components, ensuring the safety in transportation and storage. The whole has the characteristics of simple structure and convenient use.

The diaphragm piercing mechanism of the present invention utilizes the central axis buckle-type spring system. Under the state of storage and transportation, the support rod is under the elastic pressure of the spring, and the piercing member is located above the diaphragm and does not contact the diaphragm. Next, the piercing piece pierces the septum, allowing the two independent spaces to communicate. The support spring exists in the central shaft, which does not contact with the fluid in the tank and does not affect the reaction. It can be produced at the same time as the tube body. The central shaft can rotate 360 degrees to puncture the diaphragm.

The clamping groove of the cover body of the present invention is compatible with the clamping block on the elevating rod. When the elevating rod is pressed down, the clamping block is embedded in the clamping groove, so that the puncturing piece punctures the diaphragm and realizes the positioning of the puncturing piece.

The tank wall pressure early warning device of the invention senses that the pressure in the tank reaches a critical value, releases the valve switch, and sprays out a semi-fluid reaction product.
