Description

Spraying mechanism with locking device

The invention mainly discloses a spraying mechanism, in particular to a spraying mechanism with a locking device, which can be selectively changed between a locking position and a releasing position, the locking device being positioned at a locking position, and the spraying mechanism is Has a locking function and cannot spray liquid.

The spray gun structure of the conventional spray liquid agent, such as a hand-press paint spray gun, is provided with a press nozzle at the top of the tank body capable of containing the liquid agent, so that the liquid agent is sprayed outward from the nozzle. This type of liquid discharge has been used for a long time. If the spray gun is not carefully and well-collected, it can be taken at will and sprayed with care. In particular, children are driven by curiosity and have a fun attitude. It is easy to get spray guns and spray around, causing environmental problems. However, the more serious problem is that every time the spray gun is sprayed, it must be washed immediately. Otherwise, most of the liquids are made of chemical substances, which are very toxic and very easy to accumulate in the human body and endanger health. If the child directly takes the food inlet after spraying, it will directly eat the chemical liquid, which is really a big invisible killer, which seriously endangers human health. In addition, if the spray gun is not observed or sprayed toward vulnerable parts of the body such as eyes, it will be more likely to cause permanent damage.

Due to the significant lack of the above enumeration, a spray gun structure with a safety device has emerged. The safety device has various types of safety devices, such as a safety device that is pivotally connected to the pressing nozzle, and is a metal frame that is sleeved on the pressing nozzle by pivoting the frame so that the pressing nozzle cannot be pressed. The liquid material is extracted; the other safety device is a single-part external type, which is generally U-shaped, and a hook portion is respectively extended at the U-shaped open end, and the U-shaped safety device is separately hooked The pressing nozzle and the nozzle are pressed to restrict the pressing nozzle from being pressed to extract the liquid.

However, there are still many defects in the above-mentioned conventional safety devices. The safety device that is pivotally connected to the pressing nozzle needs to apply a force to the pressing nozzle, and the other hand simultaneously pivots the frame to be sleeved on the pressing nozzle, and the user cannot operate with one hand. Therefore, it is not fast and convenient at work. Furthermore, if the single part is connected to the U-shaped safety device, the user still needs to apply a force to press the nozzle, and the other hand simultaneously hooks the U-shaped safety device between the pressing nozzle and the nozzle, and the same operation cannot be performed by one hand, and The U-shaped safety device is a separate single component that is prone to loss and cannot be easily purchased.

Therefore, in order to improve the safety of the structure of the conventional spray gun and the convenience of the safety device, the inventors have been working on the concept of improving the working mechanism to make the work more convenient, and provide a spraying mechanism with a locking device. The user operates with one hand and selectively changes the locking device between the locking position and the release position. When the locking device is positioned in the locking position, the spraying mechanism has a locking function and cannot spray the liquid.
