The disadvantage of this utility model is that the device is fixedly installed with the embedded part, which is not easy to disassemble, and it is also easy to retain dirt after long-term use. Utility Model Content

[0004] The utility model aims to overcome the drawback that the deodorizing device fixed with the embedded parts in the prior art is difficult to disassemble, and provides a pre-embedded deodorizing exhaust device which can be quickly disassembled and assembled at a pipe opening.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The filter assembly is installed inside the placement tube and placed at the lower end of the placement tube. The filter assembly is detachably connected to the placement tube. The blocking assembly is installed at the lower end of the placement tube. A lifting assembly is installed on the blocking assembly.

[0007] The placement pipe can be quickly inserted into the pipe mouth of the embedded part, and the used sewage flows into the embedded part pipe through the placement pipe. When the sewage flows out of the placement pipe, it is filtered by the filtering component to prevent garbage from entering the pipe and preventing the pipe from being blocked. The filtered sewage flows out from the lower end of the placement pipe. When the sewage is not treated, the blocking component at the lower end of the placement pipe is fitted with the placement pipe to close the placement pipe to prevent the odor from flowing back. At the same time, a lifting component is installed at the upper end of the blocking component, and the lifting component can be used to drive the blocking component to rise and fall, so as to realize the opening and closing of the placement pipe. When treating sewage, the blocking component is raised to open the lower end of the placement pipe to release sewage. When sewage is not discharged, the blocking component is lowered to close the lower end of the placement pipe to prevent the odor from flowing up, thereby achieving the purpose of the odor-proof exhaust device that can be quickly disassembled and assembled at the pipe mouth.

[0008] Preferably, a limiting ring is installed at the upper end of the placement tube, and a plurality of support blocks distributed in a circle are installed on the inner wall of the placement tube. The filter assembly includes a support ring and a filter screen, and the filter screen is installed inside the support ring. The support ring corresponds to the inner wall of the placement tube, and the bottom surface of the support ring is placed on the support block. A limiting ring is provided at the upper end of the placement tube, and the limiting ring limits the placement tube in the embedded pipeline to prevent it from falling. A support block is installed in the placement tube, and a filter assembly is placed on the support block. The support ring of the filter assembly is placed on the support block, and the outer side surface of the support ring fits with the inner wall of the placement tube. Sewage can be filtered through the filter screen installed on the support ring. When used for a long time, the filter assembly can be taken out for cleaning to ensure the cleanliness of the filter assembly and prevent blockage. Such a design can filter sewage.

[0009] Preferably, the blocking assembly includes a blocking ring and a blocking ball, wherein the blocking ring is mounted on the bottom surface of the placement tube, the blocking ball is placed in the placement tube, and the lower end of the blocking ball is fitted with the inner wall of the blocking ring. The blocking ring of the blocking assembly is mounted on the lower bottom surface of the placement tube, and the blocking ball is placed in the placement tube. When the lifting assembly drives the blocking ball to descend and fits with the inner ring of the blocking ring, the blocking ring can be sealed. The sealed blocking ring can prevent odor from rising, thereby achieving odor-proof treatment of the embedded pipe fittings. When sewage needs to flow, the blocking ball is raised by the lifting assembly to open the blocking ring to allow sewage to flow down, thereby achieving normal water flow in the pipeline. Such a design can seal the pipe opening.

[0010] Preferably, the lifting assembly includes a connecting rod and a lifting rod, the lower end of the connecting rod is connected to the blocking ball, the upper end of the connecting rod passes through the filter and is placed on the upper end of the placement tube, and the upper end of the connecting rod is connected to the lifting rod. The connecting rod of the lifting assembly is connected to the blocking ball, which can drive the blocking ball to rise and fall. The connecting rod is connected to the blocking ball, and the blocking ball can be lifted by the lifting rod installed on the upper end of the connecting rod. The connecting rod passes through the filter and is placed on the upper end. When the filter needs to be removed for cleaning, the filter can be driven to take out the placement tube through the blocking ball. Such a design can quickly lift the blocking ball.

The top surface of the placement tube is provided with a fixed groove, and the two fixed grooves are provided and respectively match the two ends of the lifting rod. The top surface of the placement tube is provided with a lifting groove, and both ends of the lifting rod are placed in the lifting groove. The lifting rod moves up and down along the lifting groove, which can limit the moving direction of the lifting rod. The lifting groove can also prevent the blocking ball from rolling. At the same time, a fixed groove is provided on the top surface of the placement groove, which also corresponds to the two ends of the lifting rod. When it is necessary to release sewage, the lifting rod drives the connecting rod and the blocking ball to rise. In order to achieve continuous water flow, the lifting rod is rotated, and the two ends of the lifting rod are rotated to the top of the fixed groove and then placed in the fixed groove for fixing, and the blocking ball is kept away from the blocking plate. Such a design can ensure continuous water flow in the placement tube.

[0012] Preferably, a handle groove is provided in the limiting ring, a handle ring is provided in the handle groove, the cross-section of the handle ring is semicircular, both ends of the handle ring are rotatably connected to the inner wall of the handle groove, and a buckle groove is provided on the limiting ring, and the buckle groove is connected to the handle groove.
