The characteristics of this structure are, make humidity transducer not influenced by the environment of drenching with the rain through increase the water receiving tank structure in humidity transducer's top, and the right angle concave part on the backshell provides accommodation space for addding of water receiving tank, and the effect of L shape drainage muscle then prevents to drench and down flow along the cell wall between boss and the water receiving tank rear side on the backshell to drench humidity transducer, cause the interference to its normal work.

The water receiving tank has slope in the bottom of the tank and inclined downwards toward the center of the electric appliance box, and has water outlet in the lower side and slope of 0-10 deg. The structure is characterized in that the slope is additionally arranged so that water flow falling into the water receiving tank can flow downwards directly, and the water flow is prevented from flowing downwards along the tank wall of the water receiving tank to the humidity sensor.

According to a further scheme, the L-shaped drainage rib comprises a long edge part and a short edge part, an avoidance area is arranged on the edge of the water receiving groove close to one side of the rear shell, the long edge part of the L-shaped drainage rib penetrates through the avoidance area by a boss in the front-back direction and extends to the upper part of the water receiving groove, and the back edge of the water receiving groove and the front edge of the long edge part form a lap edge distance of 0-10 mm; the short edge part is arranged on the side with the high bottom surface of the water receiving tank, and the front edge of the short edge part is flush with the front edge of the long edge part. The effect of this structure is that long limit portion will drench the rivers guide to the water receiving tank at the boss part of humidity transducer top, and the design of dodging the district makes the rivers that leave on the long limit portion can not trickle to humidity transducer along the lower surface of the leading edge of long limit portion toward long limit portion, dodges the lower edge in district and can block down rivers that flow.

The further proposal is that the distance between the short edge part and the side edge of the water receiving groove with the high bottom edge is 0-10 mm. This structural design's purpose is in order to make the water that flows onto the water receiving tank from L shape drainage muscle can fall into the water receiving tank completely, avoids the short limit portion of L shape drainage muscle to surpass the outside of water receiving tank to lead to rivers to surpass the high one side border of base and flow on the water receiving tank from L shape drainage muscle, disturb humidity transducer's normal work at last.

In a further scheme, the L-shaped drainage rib and the rear shell are integrated; the mounting bracket and the water receiving tank are integrated with the electric appliance box. The structure is characterized in that the drainage ribs and the mounting support are designed to be integrated with the electrical box, so that the production procedures are reduced, and the production cost is saved.

According to the anti-rain structure of the humidity sensor, the water receiving groove structure is designed above the position of the original humidity sensor and used for blocking water flow above the humidity sensor, the bottom of the water receiving groove structure is provided with the inclined plane which can guide the water flow collected in the water receiving groove to the side to discharge water, meanwhile, the L-shaped water drinking rib is designed on the rear shell close to the water receiving groove, the purpose of the structure is to guide the water flow falling on the boss position above the humidity sensor to the water receiving groove, the anti-rain structure achieves anti-rain testing of the humidity sensor through the design of the structure, and the structure is simple, exquisite and remarkable in effect.
