DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] The utility model provides Figure 1-Figure 5 An automatic limit fire extinguisher head shown in the figure comprises a valve body assembly 1, a lifting handle 2 and a pressing handle 3, the lifting handle 2 is fixedly mounted on the valve body assembly 1, the lifting handle 2 and the pressing handle 3 are rotatably connected by a hinge, the top of the valve body assembly 1 passes through the two side surfaces of the lifting handle 2 and is located between the lifting handle 2 and the pressing handle 3, a monitoring component is arranged on the pressing handle 3, a second flap 7 is arranged on both sides of the pressing handle 3, an opening and a limit hole 8 are arranged on the second flap 7, the opening and the limit hole 8 are communicated with each other, a safety pin 9 is movably arranged on the inner wall of the limit hole 8, the safety pin 9 is adapted to the limit hole 8, and the safety pin 9 is rotatably connected to the lifting handle 2 through a driving component;

[0025] When using the fire extinguisher head, the safety pin 9 is automatically limited in the limit hole 8 of the pressure handle 3 through the driving component. When a fire occurs, through the monitoring component, if the measured temperature exceeds the set value, the driving component is started to drive the safety pin 9 to rotate, and the second flap 7 is disengaged from the limit hole 8 and the opening in turn, thereby canceling the rotation restriction of the lifting handle 2 and the pressure handle 3. Pressing the pressure handle 3 downward can press the top of the valve body assembly 1 to open the valve body, thereby extinguishing the fire. By automatically limiting the installation of the safety pin 9, the manual method of manually installing the safety pin 9 is replaced to meet the needs of people who do not know how to use the safety pin 9. When a fire occurs, the safety pin 9 automatically cancels the limit, so that the fire extinguisher can be used normally, and the fire can be quickly extinguished at the first time, and the opportunity to put out the fire will not be missed;

[0026] When the fire is extinguished and the temperature detected by the monitoring component is within the set value range, the driving component drives the safety pin 9 to reverse and enter the limit hole 8 through the large-diameter opening to limit the rotation between the handle 2 and the pressure handle 3 again to prevent accidental pressing of the pressure handle 3;

[0027] Furthermore, the monitoring component includes a first flap 4, a temperature touch sensor 5 and a display screen 6. The first flap 4 is fixedly arranged at the end of the pressure handle 3, the temperature touch sensor 5 is fixedly installed on the side of the first flap 4 away from the pressure handle 3, and the display screen 6 is fixedly installed on the top of the temperature touch sensor 5 through a connecting rod. The temperature touch sensor 5 is a non-contact temperature touch sensor 5, and the measured temperature value is displayed through the display screen 6, so that the fire extinguishing personnel can know the temperature of the flame at this time to prevent re-ignition.

[0028] Furthermore, the driving assembly includes a rotating shaft 12, which is rotatably arranged at the bottom of the handle 2, and a first gear 13 is fixedly arranged at the outer ring in the middle of the rotating shaft 12. A motor box 14 is also arranged at the bottom of the handle 2, and a motor is arranged inside the motor box 14. The driving end of the motor movably passes through the side wall of the motor box 14, and a second gear 15 is arranged on one end passing through the side wall of the motor box 14, and the second gear 15 is meshed with the first gear 13. A rotating rod 16 is rotatably arranged on the end of the rotating shaft 12 that movably extends out of the two sides of the handle 2, and a second plug hole is arranged on the end of the rotating rod 16 away from the rotating shaft 12. The inner wall of the second plug hole is movably fitted with the outer surface of the safety pin 9. Starting the motor causes the second gear 15 to drive the first gear 13, the rotating shaft 12 and the rotating rod 16 to rotate, thereby driving the safety pin 9 to rotate, automatically limiting in the limiting hole 8, or automatically canceling the limit, so that the fire can be directly extinguished after directly pressing the pressure handle 3.

[0029] Taking into account that the traditional method of manually canceling the limit of the safety pin 9 is more suitable for people who know how to operate the safety pin 9, the utility model will also retain the method of manually canceling the limit of the safety pin 9. Specifically, a first plug hole 902 is provided on one end of the safety pin 9, and a plastic rod 903 is slidably provided in the first plug hole 902. A pull ring 901 is fixedly provided on the other end of the safety pin 9. After the plastic rod 903 is pulled out of the first plug hole 902, the pull ring 901 is pulled out by the fingers, thereby pulling the safety pin 9 out of the two rotating rods 16, thereby canceling the rotation restriction of the handle 2 and the pressure handle 3, so that the limit of the safety pin 9 can be canceled without the need for a driving component.

[0030] In order to avoid dropping the safety pin 9 when pulling out the safety pin 9, a fixing ring 10 is fixedly provided at the bottom of the handle 2, and the fixing ring 10 and the pull ring 901 are flexibly connected by a connecting rope 11, so that the connecting rope 11 can prevent the safety pin 9 from being lost after being pulled out, and the fire extinguisher can be used again after use.

[0031] Furthermore, third flaps are provided on both sides of the handle 2 , and the third flaps are movably fitted with the second flaps 7 . Such an arrangement allows the pressing handle 3 to stably rotate on the handle 2 .
