Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Example one
As shown in fig. 1-2, an air curtain structure oil smoke sensor comprises an oil smoke sensor body, wherein the oil smoke sensor body comprises a base 1, a lens 2 and an upper cover 3, the lens 2 is fixed on the base 1 through the upper cover 3, the upper cover 3 and the base 1 are installed, an air curtain channel 6 is arranged in front of the lens 2, a detection air channel 7 is arranged in the middle of the air curtain channel 6 on two sides, namely, the air curtain channel 6 is used for blocking air in the detection air channel 7 from entering the position of the lens 2. The air curtain channel 6 comprises an air curtain channel air inlet 8 and an air curtain channel air outlet 4, the air curtain channel air inlet 8 is connected with a vent pipe 10 in a sealing mode, and therefore the lens pollution caused by oil smoke entering is avoided; the vent pipe can adopt a vent hose, a metal pipe or a plastic pipe and the like. The ventilation pipe 10 is connected to a position where fresh air exists, and external clean air enters the air inlet 8 of the air curtain channel through the ventilation pipe 10 and flows out through the air outlet 4 of the air curtain channel. The detection air channel 7 comprises a detection air channel air inlet 9 and a detection air channel air outlet 5, air entering the detection air channel air inlet 9 flows out of the detection air channel air outlet 5, and an air curtain channel air inlet 8 is separated from the detection air channel air inlet 9. The air inlet 8 of the air curtain air channel is larger than the air inlet 9 of the detection air channel, so that the phenomenon that the air curtain formed by clean air is damaged due to the fact that the air quantity of the air inlet 9 of the detection air channel is large to influence the air flow direction is avoided, and lens pollution is caused. As shown in fig. 3, the air curtain channel 6 is made in a long and narrow shape, and the width of the air curtain channel is larger than the exposed size of the lens 2, so that clean air forms an air curtain to effectively and completely block air in the detection area from entering the lens, thereby avoiding detection errors caused by dust and oil deposition on the lens 2.
The utility model discloses a theory of operation is:
utilize clean air to form the air admission lens in the air curtain separation detection area in lens 2 the place ahead, reduce air pollution and cause the dust to adhere to on the lens, specifically lead to clean air through air curtain passageway air inlet 8, owing to be separated with detection wind channel air inlet 9, so detect the air that wind channel air inlet 9 got into just can not enter into the lens through the air curtain that clean air formed on, just so reduced the contaminated possibility of lens. The requirements are that the air inlet 9 of the detection air channel and the air inlet 8 of the air curtain channel respectively enter air, and the air entering through the air inlet 8 of the air curtain channel is clean air.
Example two
The difference from the first embodiment is only that, as shown in fig. 4-5, the air outlet of the air curtain channel and the air outlet of the detection air channel are designed to be the same air outlet, that is, the air is exhausted from the air outlet 5 of the detection air channel, so that the space can be saved.
EXAMPLE III
The only difference from the first or second embodiment is that the smoke sensor is a dust sensor.
Finally, it should be noted that: the above embodiments are only used for illustrating the present invention and do not limit the technical solution described in the present invention; thus, while the present invention has been described in detail with reference to the various embodiments thereof, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted; all such modifications and variations are intended to be included herein within the scope of this disclosure and the present invention and within the scope and spirit of the following claims.
