Description

Technical Field

[0001] The invention belongs to the technical field of intelligent fire-fighting kitchens, and in particular relates to a novel kitchen smoke pipe capable of automatically extinguishing fire. Background Art

[0002] The kitchen fumes are very heavy, and the range hood discharges the fumes to the outside through the flue. The kitchen is also a high-incidence area for fires, especially those caused by oil pan fires. The open flame enters the flue through the path and causes the oil stains inside to burn, making it difficult to extinguish the fire because it is difficult for personnel to see the internal situation and cannot extinguish the fire in time, which may cause a huge fire risk.

[0003] In view of this, the present invention is proposed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new type of kitchen smoke pipe that can automatically extinguish fire. To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0005] A novel kitchen smoke pipe capable of automatically extinguishing fire comprises a smoke pipe, a side box is fixedly arranged on one side of the surface of the smoke pipe, and a hollow net made of combustible material is fixedly arranged inside the smoke pipe below the side box, a gravity sensor is embedded and bonded on the hollow net, a suspension rod is vertically fixed on both sides above the inner wall of the side box, and a high-pressure dry powder bottle is rotatably hinged on the inner side of the lower end of the suspension rod, a driven gear is fixedly arranged on the upper surface of the high-pressure dry powder bottle, and a stepping motor is fixed on the top wall of the side box above the high-pressure dry powder bottle, and a driving gear is fixed on one end of the output shaft of the stepping motor, and The driving gear and the driven gear are meshed for transmission, an electric valve is sealed and connected on one side of the surface of the side box close to the smoke pipe, and the output port of the electric valve is connected to the output pipe through a sealed bearing, the output pipe penetrates into the interior of the smoke pipe and is connected to a release pipe, the upper and lower surfaces of the release pipe are fixedly connected to a plurality of dry powder release heads, and the release pipe is fixedly arranged above the hollow net, a controller is fixed on the inner bottom wall of the smoke pipe, the gravity sensor is electrically connected to the controller through an electric wire of interference length that penetrates into the interior of the side box, and the controller is electrically connected to the stepping motor and the electric valve respectively through lines.

[0006] Furthermore, the surfaces of the hollow net and the gravity sensor are coated with corrosion-resistant paint.

[0007] Furthermore, the smoke pipe, the hollow net and the release pipe are all arranged in a circular shape.

[0008] Furthermore, the gravity sensor is arranged at the center of the hollow net.

[0009] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0010] During normal use, the temperature of the oil smoke flowing in the smoke pipe is not high in the flue, and will not affect the hollow mesh. When a flame occurs inside the smoke pipe, the hollow mesh will be burned by the open flame, and its gravity sensor will fall down. The gravity sensor immediately transmits the signal to the controller. After receiving the signal, the controller will first control the output shaft of the stepper motor to rotate back and forth at a certain angle, and drive the high-pressure dry powder bottle to shake through the driving gear and the driven gear to mix the internal gas and powder, and then control the electric valve to open, and the dry powder in the high-pressure dry powder bottle will enter the release pipe and be sprayed out through the dry powder release head to extinguish the open flame.

DETAILED DESCRIPTION

The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] like Figures 1 to 4 As shown, a new type of kitchen smoke pipe with automatic fire extinguishing comprises a smoke pipe 1, a side box 2 is fixedly arranged on one side of the surface of the smoke pipe 1, and a hollow net 3 made of combustible material is fixedly arranged inside the smoke pipe 1 below the side box 2, a gravity sensor 4 is embedded and bonded on the hollow net 3, a suspension rod 5 is vertically fixed on both sides above the inner wall of the side box 2, and a high-pressure dry powder bottle 6 is rotatably hinged on the inner side of the lower end of the suspension rod 5, a driven gear 7 is fixedly arranged on the upper surface of the high-pressure dry powder bottle 6, and a stepping motor 8 is fixed on the top wall of the side box 2 above the high-pressure dry powder bottle 6, a driving gear 9 is fixed on one end of the output shaft of the stepping motor 8, and the driving gear 9 is fixed on the upper surface of the high-pressure dry powder bottle 6. 9 is meshed with the driven gear 7 for transmission. The surface of the side box 2 is sealed and connected to the side of the smoke pipe 1, and the output port of the electric valve 10 is connected to the output pipe through a sealed bearing. The output pipe penetrates into the interior of the smoke pipe 1 and is connected to a release pipe 12. The upper and lower surfaces of the release pipe 12 are fixedly connected to a plurality of dry powder release heads 13, and the release pipe 12 is fixedly arranged above the hollow net 3. A controller 11 is fixed to the inner bottom wall of the smoke pipe 1. The gravity sensor 4 is electrically connected to the controller 11 by an electric wire of an interference length that penetrates into the interior of the side box 2, and the controller 11 is electrically connected to the stepping motor 8 and the electric valve 10 through lines. During normal use, the temperature of the oil smoke flowing in the smoke pipe 1 is not high in the flue, and will not affect the hollow net 3. When a flame occurs inside the smoke pipe 1, the hollow net 3 will be burned by the open flame, and its gravity sensor 4 will fall downward. The gravity sensor 4 immediately transmits a signal to the controller 11. After receiving the signal, the controller 11 will first control the output shaft of the stepper motor 8 to rotate back and forth at a certain angle, and drive the high-pressure dry powder bottle 6 to shake through the driving gear 9 and the driven gear 7 to mix the internal gas and powder, and then control the electric valve 10 to open, and the dry powder in the high-pressure dry powder bottle 6 will enter the release tube 12 and be sprayed out through the dry powder release head 13 to extinguish the open flame.

[0021] The surfaces of the hollow net 3 and the gravity sensor 4 are coated with corrosion-resistant paint to prevent their performance from being affected by long-term oil smoke contamination during daily operations.

[0022] In this example, the smoke tube 1, the hollow net 3 and the release tube 12 are all arranged in a circular shape with reasonable structure. The gravity sensor 4 is arranged at the center of the hollow net 3 and can fall down in time when the hollow net 3 is damaged.

[0023] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
