Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
Example one
As shown in fig. 1-3, a smoke sensor comprises a smoke sensor body, which comprises a base 1, a shielding case 2, an upper cover 3, a smoke inlet 4 and an air outlet 5. The upper cover 3 covers the base 1, and the base 1 is provided with a PCBA circuit board 6, a light emitting tube 7 and a light receiving tube 8. The shielding case 2 covers the upper cover 3; the left side of the base 1 is provided with a left fresh air inlet 9, and the right side of the base 1 is provided with a right fresh air inlet 10. The airflow entering from the left fresh air inlet 9 flows into the air outlet 5 through the left airflow port 11 of the base 1, and is discharged: the airflow entering from the left fresh air inlet 9 is collected to the oil smoke pollution airflow path 15 along the left fresh air flow path 13 and discharged. The airflow entering from the right fresh air inlet 10 flows into the air outlet 5 through the right airflow port 12 of the base 1, and is discharged: the airflow entering from the right fresh air inlet 10 is discharged along the right fresh air flow path 14 and converged to the oil smoke pollution airflow path 15. Compared with the prior art, the design scheme omits lenses on two sides, the left side and the right side of the base 1 are provided with the fresh air inlets, and the problem that the light emitting tube 7 and the light receiving tube 8 are polluted by oil smoke is avoided through positive double air flows of the fresh air inlets on the left side and the right side.
As a preferred scheme, the outsides of the left fresh air inlet 9 and the right fresh air inlet 10 both adopt pagoda mouth structures, so that the left fresh air inlet and the right fresh air inlet are conveniently connected with a hose.
Preferably, the air inlet is arranged in the middle of the base.
Meanwhile, it should be noted that the left air flow port 11 and the right air flow port 11 are integrated on the base, and are plastic cavities, which is prior art, and therefore, will not be described in detail herein.
The following brief description is the working principle of the present invention:
firstly, the outside fresh air flows into the fresh air inlets (9, 10) on the left and right sides of the base 1 respectively, then flows into the oil smoke pollution airflow path 15 along the fresh air airflow paths (13, 14) on the left and right sides respectively, namely through the airflow ports (11, 12) on the left and right sides respectively, and finally is discharged through the air outlet 5. The external oil smoke gas flow flows into the oil smoke air inlet 4 and is discharged through the air outlet 5, namely, the external oil smoke gas flow flows along the oil smoke pollution gas flow path 15 and is finally discharged through the air outlet 5.
Finally, it should be noted that: the above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention; thus, while the present invention has been described in detail with reference to the foregoing embodiments, 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 protected by the following claims.
