Description
Technical Field
The utility model relates to a part for oil extraction cigarette fire prevention check valve, in particular to control by temperature change fuse-link for oil extraction cigarette fire prevention check valve.
Background
The fume exhauster is also called as fume exhauster, and is a kitchen electric appliance for purifying kitchen environment. The smoke exhaust ventilator is arranged above a kitchen range of a healthy energy-saving kitchen range hood, can rapidly exhaust waste burnt by the kitchen range and oil smoke harmful to human bodies generated in the cooking process, and exhaust the waste and the oil smoke to the outside, reduces pollution, purifies air, and has the safety guarantee effects of gas defense and explosion prevention.
Related with current house design, there is the potential safety hazard in the installation use of current lampblack absorber. At present, in many high-rise apartments, families of multiple households share the same flue, exhaust pipes of range hoods are connected to the same flue, when fire occurs in the flue, the fire easily enters the room along the pipeline of the range hoods through the flue, and fire disasters are caused, so that the high-rise apartment is extremely unsafe.
The similar products in the existing market have the following defects: if the extension spring fuses, or other reasons cause extension spring and depression bar to part the back, the door plant loses the pressure of depression bar, and the door plant still will open, uses not safe enough.
In addition, the existing similar products in the market have the following defects: the temperature control fuse link for hooking the pressure lever has low fusing speed, and is not beneficial to closing the air door panel after rapid fusing.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to sell not enough of product technique on the existing market, a control by temperature change fuse-link for oil extraction gas fire prevention check valve is provided.
In order to achieve the above object, the present invention takes the following measures:
a temperature control fuse link for a fire-proof check valve of oil smoke exhaust comprises a temperature control fuse link body, wherein the temperature control fuse link body is an integral structure formed by bending a brass sheet with a length, the melting point of the temperature control fuse link body is not more than 150 ℃, and the temperature control fuse link body comprises an installation part and a hooking part installation part, and is provided with at least two installation holes;
one end of the outer side of the mounting part, which is far away from the hooking part, is provided with a clearance groove;
the bending angle of the brass sheet is 90 degrees, and the metal plate with one length is continuously bent for two 90 degrees to form a hooking part.
The utility model has the advantages that: the practicality, low in production cost, safe in utilization when meetting the condition of a fire, control by temperature change fuse link body can fuse rapidly, and fusing is fast, and the depression bar of oil extraction flue gas fire prevention check valve breaks away from the restriction of control by temperature change fuse link body, at the effect of extension spring, pushes down the wind door board, plays the effect of fire prevention, and is safe in utilization.

Detailed Description
A temperature control fuse link for a fire-proof check valve of oil smoke exhaust comprises a temperature control fuse link body 9, wherein the temperature control fuse link body 9 is an integral structure formed by bending a brass sheet with a length, the melting point of the temperature control fuse link body 9 is not more than 150 ℃, the temperature control fuse link body 9 comprises an installation part 9-1 and a hooking part 9-2, and at least two installation holes 9-3 are formed in the installation part 9-1.
One end of the outer side of the mounting part 9-1, which is far away from the hooking part 9-2, is provided with a clearance groove 9-4. The clearance groove 9-4 can play a role in mounting and avoiding the beam on the fireproof check valve for oil smoke discharge, and meanwhile, the fusing of the temperature-controllable fuse link body 9 is accelerated.
The bending angle of the brass sheet is 90 degrees, and the brass sheet with one length is continuously bent for two 90 degrees to form a hooking part 9-2.
The utility model discloses a fix with screw can on oil smoke fire prevention check valve (the screw passes installation department 9-1 and goes up one of them mounting hole 9-3), there is not the condition of a fire, and in the time of normal use, the depression bar on the oil smoke fire prevention check valve of arranging hooks on the portion 9-2 that hooks of control by temperature change fuse-link body 9, and the wind door plant can rotate along the pivot, can open the oil smoke hole of arranging, reaches the effect that the lampblack absorber took out oil smoke.
When meeting the condition of a fire, control by temperature change fuse-link body 9 meets the intensity of a fire (high temperature exceeds 150 ℃), control by temperature change fuse-link body 9 melts rapidly, and the depression bar receives the pulling force of extension spring, and the depression bar removes to one side of keeping away from the pivot, and the depression bar extrusion is on the wind door plant, and the wind door plant can not be opened, and the wind door plant blocks up oil extraction flue gas hole, plays the effect of fire prevention. The temperature control fuse link body 9 is not provided with mounting holes 9-3 for screws to pass through, so that flame in fire can pass through the temperature control fuse link body, and the fusing of the temperature control fuse link body 9 is accelerated.
The present application can refer to the utility model No. 201621279784.7 patent of the applicant, which is named as: a fire-proof check valve for oil smoke discharge.
