Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishers, in particular to a fire extinguisher with a sustainable jetting valve. Background Art

[0002] Dry powder fire extinguisher is a kind of fire extinguisher. According to the type of dry powder fire extinguishing agent filled, it can be divided into ordinary dry powder fire extinguisher and ultrafine dry powder fire extinguisher. According to the mobility, it can be divided into three types: portable, backpack and cart-type. The fire extinguisher is filled with dry powder fire extinguishing agents such as ammonium phosphate salt. This dry powder fire extinguishing agent is easy to flow and dry. It is composed of inorganic salts and crushed and dried additives, which can effectively extinguish initial fires. Dry powder fire extinguisher uses carbon dioxide gas or nitrogen gas as power to spray out the dry powder in the cylinder, which can extinguish general fires, and can also extinguish fires caused by the combustion of oil, gas, etc. When using a dry powder fire extinguisher, it is necessary to press the pressure handle of the fire extinguisher for a long time to achieve the purpose of continuous fire extinguishing.

[0003] When using existing small dry powder fire extinguishers, sometimes according to the fire situation at the scene, it is necessary to continuously spray the fire. In order to achieve the purpose of continuous spraying, some small dry powder fire extinguishers currently need to press the handle for a long time to press the valve stem down to keep the inside of the fire extinguisher connected to the outside. However, long-term pressing will cause muscle soreness of the operator, making it difficult to maintain the pressing state, which delays the fire extinguishing work and causes property losses to people.

[0004] For this purpose, we propose a fire extinguisher with a continuous jet valve. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: a fire extinguisher with a continuous jetting valve, comprising a bottle body 1, a safety pin 5, a pressure handle 2, a lifting handle 3, a valve body 7, a valve stem 8 and a first spring 10, wherein a guide seat 13 is fixedly connected to one side of the valve body 7 close to the lifting handle 3, the guide seat 13 is located at the top of the valve body 7, a lock hole is provided on the outer wall of the guide seat 13, a siphon base 9 is fixedly connected to the bottom of the valve body 7, a siphon tube 4 is fixedly connected to the inside of the siphon base 9, an L-shaped connecting port 12 is arranged inside the valve body 7, the connecting port 12 can be connected to an external nozzle, the connecting port 12 is respectively connected to the inside and outside of the bottle body 1, one end of the valve stem 8 is fixedly connected to the first spring 10, and the other end of the valve stem 8 is fixedly connected to the first spring 10. The guide seat 13 is penetrated and extends to the outside of the guide seat 13. A slot 15 is provided on the valve stem 8 near the lifting handle 3. The opening direction of the slot 15 is the same as the external direction of the communicating port 12. A locking mechanism 6 is provided on the valve body 7, which is locked with the slot 15 through a locking hole. When the pressing handle 2 is pressed downward, the locking mechanism 6 can automatically cooperate with the slot 15 to complete the locking and positioning of the valve stem 8. The slot 15 can be separated from the locking mechanism 6 by manually driving the locking mechanism 6. The locking mechanism 6 includes a mounting seat 61 fixedly connected to the valve body 7. A cavity 67 is provided inside the mounting seat 61. The cavity 67 is communicated with the locking hole. A locking member 67 is placed near the valve stem 8 in the cavity 67. The card slot 15 cooperates with the buckle 66, one end of the buckle 66 is fixedly connected to the second spring 65, the other end of the second spring 65 is fixedly connected to the push plate 64, and the side of the push plate 64 away from the second spring 65 is fixed with a screw 63 threadedly matched with the mounting seat 61, and the screw 63 extends to the outside of the mounting seat 61 and is fixedly connected to the rotating disk 62; in the initial state, the buckle 66 is in conflict with the outer wall of the valve stem 8 under the action of the second spring 65; when in use, when the fire extinguisher needs to be used, first press the pressure handle 2 downward, and the pressure handle 2 drives the valve stem 8 to move downward while moving downward. In the process of the valve stem 8 moving downward, the inside of the bottle body 1 is connected with the outside due to the movement of the valve stem 8, and the bottle body 1, the dry powder inside is sprayed out to the outside of the fire extinguisher through the siphon tube 4 and the connecting port 12 in turn through the siphon effect; the valve stem 8 is pressed downward continuously, and when the slot 15 on the valve stem 8 moves to the position corresponding to the buckle 66, the buckle 66 will extend into the slot 15 under the action of the second spring 65 to limit and fix the valve stem 8. At this time, the operator does not need to keep pressing with his hands; when the fire is extinguished, the rotating disk 62 is rotated, and the rotating disk 62 drives the screw 63 to rotate outward. The outward rotation of the screw 63 drives the second spring 65 to move outward through the push rod, thereby driving the buckle 66 to separate from the slot 15. The valve stem 8 separates the inside of the bottle body 1 from the outside again under the action of the first spring 10, and the dry powder stops spraying;This patent uses the first spring 10, the second spring 65, the buckle 66, the slot 15 and the screw 63. When the valve stem 8 is pressed down by the pressure handle 2, the valve stem 8 is limited and locked by the cooperation of the buckle 66 and the slot 15, so that the operator can continue to spray dry powder without continuously pressing the pressure handle 2, saving the operator's physical strength and improving the efficiency of fire extinguishing. In addition, the screw 63 drives the buckle 66 to move through the second spring 65, which is simple to operate and can block the spraying of dry powder at any time, improving the flexibility of the device. ;

[0021] The buckle 66 is a cylindrical structure with a hollow interior, and the buckle 66 is open toward one end of the second spring 65. The second spring 65 extends into the interior of the buckle 66 through the opening and is fixedly connected to the inner bottom of the buckle 66. When in use, the buckle 66 is designed to be a cylindrical structure with a hollow interior, and the second spring 65 extends into the interior of the buckle 66 and is fixedly connected to the buckle 66, which can support and guide the movement of the second spring 65, making the movement of the buckle 66 more stable.

[0022] The mounting seat 61 is fixedly installed on the top of the valve body 7 and on the same side as the connecting port 12; when in use, the mounting seat 61 is fixedly installed on the top of the valve body 7 and on the same side as the connecting port 12, which can avoid interference with other components and facilitate operation of the locking mechanism 6, thereby improving the practicality of the fire extinguisher.

[0023] A guide column 11 is fixedly connected to the bottom of the valve stem 8, and the guide column 11 extends into the interior of the first spring 10; during use, the guide column 11 can guide the movement of the first spring 10, thereby improving the movement stability of the first spring 10 and extending the service life of the first spring 10.
