Anti-slipping structure of self-propelled spray can

The present invention relates to a latching safety device, in particular to a self-defense spray can, which is suitable for the structure of a trigger type nozzle, and is designed with two safety locks and a foolproof structure, which can be effectively used when the anti-body spray can is not used. Prevent accidental accidents and accidental sprays.

Due to the recent public safety-related accidents, the loss of innocent lives or damage is caused by the loss of property, and it is difficult to ensure that there are gangsters in the surrounding environment in public areas with large populations. How to protect yourself from the dangers when you are in danger, and pay attention to the importance of self-defense. In addition to professional self-defense training, the most convenient way is to carry self-defense products with you.

Commonly used in the market for self-defense and easy to carry equipment or devices, such as self-contained spray cans, crowbars, electric batons or sirens, etc., in which the crowbars are mainly folded in a plurality of rods, When in use, the rods are stretched together to form a long stick shape, which can attack the gangsters. If not used, the rod body can be retracted into the handle for easy carrying; the alarm is made of high decibel and harsh The sound spreads to ask for help or to scare off the gangsters; the electric shock stick uses high-voltage power to contact the gangster's body to stun it; the self-propelled spray can is filled with irritating liquids such as tears, capsicum and mustard extract. Wait, when the gangsters close their bodies, spray their faces, and then take the opportunity to escape.

Further analysis of the self-defense spray can, mainly using a container filled with irritating fluid such as tear liquid, capsicum and mustard extract, and using the pressure mechanism to spray the irritating fluid in the container out of the container together with the nozzle group and the valve block structure, Forming a mist of small molecules, the greater the pressure, the larger the range of fluid ejection; because such irritating fluid is sprayed on the face, it can cause irritation to the eyes, mouth and nose, but it can not blink, tears, spray Symptoms such as phlegm, cough, burning sensation and numbness can cause people to move normally and have a gap that can be escaped. With water or other means, the symptoms can be gradually relieved after tens of minutes. Self-defense liquid only makes people temporarily Temporary injury does not cause permanent damage to the body.

The nozzle application of the common self-defense tank is mainly connected with the valve group of the spray can, and is used as a driving valve group to open the fluid to flow out. The structure can be divided into "press type" and "trigger type", among which "press type" Refers to the driving action to indirectly press the valve group in a "linear manner" to open the valve group to discharge the fluid; the "trigger type" refers to the driving action to indirectly press the valve group "rotating" to open the valve group to discharge the fluid. . In general, the "trigger type" rotary drive method has a relatively large force arm, so it is less "pressing" and less labor-saving.

The "self-defense sprayer" disclosed in the Japanese Patent No. 095 218 457, which comprises a body, a body and a cap, wherein the body comprises a bottle body and a body a pressing portion at the top of the bottle body; the sleeve body is a cylindrical tube body having an opening at the top thereof and sleeved on the outside of the bottle body; the top portion of the cap has a rounded end surface and a corner, which covers the pressing portion, and Interconnected with the sleeve.

There is also a conventional self-defense tank head structure, such as the "self-defense spray can" disclosed in the Japanese Patent No. 090219220, which comprises a hand-touch type cover (10), a nozzle (31) for reducing the diameter, and a The gas pressure tank body (20), wherein: A. the hand touch type cover (10) is provided with a window (11), and the inner side of the window is provided with an orientation function board (12), and the opposite side of the window is provided with a touch shape Finger insertion port (13); B. The nozzle surface is provided with a nozzle (31) for reducing the diameter of the pipe, and can improve the energy usage rate and increase the range function, and the gas in the pressure tank body (20) is pressurized to be ejected. It does not diffuse into a mist, etc.; C. A pressure tank filled with food grade capsicum and natural gas pressure.

There is also a nozzle structure of a conventional self-defense can, such as the gas spray self-defense device with a safety switch disclosed in the new patent No. 085200499, which is composed of a body, a nozzle and a cover, and a nozzle is provided on the body. A cover is disposed outside the nozzle on the body, and an L-shaped groove is formed at the bottom of one end of the nozzle. The L-shaped groove is formed by a longitudinal groove and a horizontal groove, and protrudes inwardly at an appropriate inner surface of the cover. A tab is formed by the tab and the side L-shaped groove. When the tab abuts against the lateral groove of the side L-shaped groove, the nozzle can be prevented from being improperly pressed.

In the above-mentioned structure, the structure of the nozzle of the "press type" is to directly press the button to drive the valve body above the tank body, thereby ejecting the fluid in the tank; The conventional structure has a structural design for preventing accidental or accidental ejection, and when not used or placed in the bag, the accidental ejection of the stimulating fluid can be reduced, wherein the first and second cases are all "outer cover type". The design of the anti-stay structure is to set a cover on the outside of the nozzle to isolate the touch. In the third case, it is a "screw-type", that is, to rotate each of the tabs to the lateral groove of the side L-shaped groove. That is, the buckle can not be pressed, and each of the tabs is rotated to the position of the longitudinal groove of the side L-shaped groove, and is in a state of being press-driven.

However, the above-mentioned "push-type" nozzle structure, the safety foolproof device applied is also mainly for the prevention of the action of the linear press drive, that is, the "outer cover type" and "spin" disclosed in the above-mentioned conventional structure. The buckle type is only applicable to the "push type" nozzle structure, and cannot be applied to the "trigger type" nozzle structure. On the other hand, the conventional "push type" and "trigger type" nozzle structures are mostly provided with only one set of safety. The foolproof device, if the safety device of the group is damaged or fails, there is no other remedy or precautionary measures. Even if it has not been used up, in order to prevent accidental contact with itself, only the entire group of spray cans can be replaced; The prevention of false touches and mis-injection of the anti-staying device is not good. For example, if the protective cover is accidentally disengaged due to external force, or the tab is accidentally rotated to the position of the longitudinal groove, the probability of accidental contact and accidental ejection is still quite high; therefore, the creator of the case is directed to " The trigger type nozzle structure provides a two-way safety latching device to solve the aforementioned conventional problems.
