Abstract
The utility model discloses a lampblack absorber electric check valve, step motor in installation and lampblack absorber pipeline, step motor passes through the control panel of circuit and lampblack absorber and links to each other, step motor passes through the screw rod and links to each other with flexible pipe, install the valve on the flexible pipe. When the range hood is opened, the control panel automatically controls the stepping motor to be opened and pushes the valve open through the telescopic pipe. When the range hood is closed, the control panel automatically controls the stepping motor to rotate reversely to pull the valve to be closed. Therefore, the opening and closing of the check valve are not affected by pipelines and other environments, and the using efficiency of the range hood is improved.
Description
Technical Field
The utility model relates to a lampblack absorber especially relates to a lampblack absorber electric check valve.
Background
The range hood is a kitchen appliance for purifying the kitchen environment. The kitchen ventilator is arranged above a kitchen stove, can rapidly pump away waste burnt by the stove and oil fume harmful to human bodies generated in the cooking process, and exhaust the waste and the oil fume to the outside, reduces pollution, purifies air, and has the safety guarantee effects of gas defense and explosion prevention.
Check valves are generally installed in the range hood to prevent oil smoke from flowing back, and the check valves in the current market are opened by using negative pressure formed by rotation of an outer fan of the range hood to push air to push a valve to open the check valves, so that oil smoke generated in a kitchen is discharged outdoors through the check valves. When the range hood is closed, the rotation of the fan of the outer machine stops, the negative pressure disappears, and the valve returns to the original position under the action of gravity, so that the valve is closed to prevent oil smoke in the pipeline from flowing back to enter a kitchen. The check valve is affected by an oil smoke pipeline and an installation environment in actual use, the problem that the valve is not opened and closed timely exists, the condition that the valve is not opened completely when the valve needs to be opened exists, and the working efficiency of the range hood is seriously affected.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a lampblack absorber electric check valve has the characteristics that can open and close the check valve automatically through motor control.
In order to achieve the aim, the utility model provides a lampblack absorber electric check valve, step motor in installation and lampblack absorber pipeline, step motor passes through the circuit and links to each other with the control panel of lampblack absorber, step motor passes through the screw rod and links to each other with flexible pipe, install the valve on the flexible pipe.
And a sealing ring is arranged between the valve and the pipeline.
And the valve in the direction connected with the telescopic pipe is in an arc design.
The utility model has the advantages that: when the range hood is opened, the control panel automatically controls the stepping motor to be opened and pushes the valve open through the telescopic pipe. When the range hood is closed, the control panel automatically controls the stepping motor to rotate reversely to pull the valve to close. Therefore, the opening and closing of the check valve are not affected by pipelines and other environments, and the using efficiency of the range hood is improved.

fig. 2 is a perspective view of the present invention.
Detailed Description
Example 1
As shown in fig. 1-2, a lampblack absorber electric check valve, including installation and the lampblack absorber pipeline in step motor 1, step motor 1 links to each other with the control panel of lampblack absorber through the circuit, step motor 1 passes through the screw rod and links to each other with flexible pipe 2, install valve 3 on the flexible pipe 2. When the range hood is opened, the control panel automatically controls the stepping motor to be opened and pushes the valve 3 open through the telescopic pipe. When the range hood is closed, the control panel automatically controls the stepping motor to rotate reversely to pull the valve 3 to close. Therefore, the opening and closing of the check valve are not affected by pipelines and other environments, and the using efficiency of the range hood is improved. And a sealing ring 4 is arranged between the valve 3 and the pipeline to increase the tightness of the valve.
And the valve 3 in the direction connected with the telescopic pipe 2 is in an arc design. The air-out resistance when the valve is opened has been greatly reduced to the arc design to increase the circulation efficiency of oil smoke when the valve is opened.
