Compared with the prior art, the utility model has the beneficial effects that:

the utility model passes through the upper ventilating layer and the lower deodorizing layer. When the odor passes through the deodorizing layer, odor molecules are decomposed through the dry chemical filter material, and the decomposed gas is discharged through the ventilating layer. The bottom of the ventilation layer is provided with a U-shaped drain pipe, so that the ground ponding can be discharged to the sewage well from the pipeline in rainy days, and the U-shaped pipe section can store water, so that the odor in the sewage well can be prevented from being directly discharged out of the ground from the drain pipe. The device has not only solved the sewage well deodorization problem, can also keep certain drainage function, and increases the back of device, can regard as anti-falling device, avoids appearing "well lid eats people".

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1:

referring to fig. 1-7, the present utility model provides a technical solution: the sewage well lid deodorizing device comprises a well lid 110, wherein a boss and a well lid plate are arranged in the well lid 110, a ventilation layer 111 is nested in a gap between the boss and the well lid plate, a plurality of drain holes 114 are formed in the well lid 110 and used for draining water, and a ventilation opening 117 is fixedly connected to the lower end wall of a cavity in the ventilation layer 111;

the diameter of the ventilation opening 117 can be designed differently according to the odor overflow amount of different sewage wells, and the height of the ventilation opening 117 is designed according to the size of different well lid reinforcing ribs;

the lower end wall of the cavity inside the ventilation layer 111 is fixedly connected with two handles 115 which are symmetrical with respect to the ventilation opening 117, the handles 115 are used for transportation and taking, and the ventilation opening 117 is connected with the deodorizing layer 113 through four symmetrically distributed bolt groups 118;
