Central air conditioner pipeline filtering mechanism

Abstract

The utility model discloses a central air-conditioning pipeline filtering mechanism in the technical field of central air-conditioning pipeline filtering, which comprises a pipeline, a fixing frame of a U-shaped structure is connected to the pipeline in an attached mode. Fixing blocks connected with a pipeline are arranged on the periphery of the bottom of the fixing frame; an outer frame is arranged on the inner wall of the fixing frame, the top of the outer frame makes contact with the pipeline, and a filter screen is arranged in the outer frame. A containing groove and a groove are formed in the inner walls of the top side and the bottom side of the outer frame correspondingly, and the right side of the containing groove and the right side of the groove are both flush with the filter screen. When the toothed bar does not fix the connecting rod, the baffle can cover the left side of the outer frame, then the connecting rod is pulled downwards, dust attached to the left side of the filter screen and scraped by the scraping rod can be blocked by the baffle and then fall into the groove to be collected, and therefore when the fixing frame is detached from the pipeline, the situation that the dust attached to the left side of the filter screen flies around can be avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning pipeline filtering, in particular to a central air-conditioning pipeline filtering mechanism. Background Art

[0002] With the continuous development and progress of society, the application of central air-conditioning has become more and more popular. Ventilation ducts are an important component of central air-conditioning. Existing central air-conditioning ventilation ducts are equipped with filters to filter dust in the air. However, during long-term use, the filters will be clogged with dust and impurities. Therefore, it is necessary to open the ventilation ducts regularly to remove the filters for cleaning.

[0003] However, the applicant found that when the ventilation duct is opened to remove the filter, dust will often fly around because dust adheres to the surface of the filter, which makes the user experience poor. Therefore, we propose a central air conditioning duct filtering mechanism. Utility Model Content

[0004] The purpose of the utility model is to provide a central air-conditioning pipeline filtering mechanism to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a central air-conditioning pipeline filtering mechanism, comprising a pipeline;

[0006] A fixing frame with a U-shaped structure is fitted and connected to the pipeline;

[0007] The bottom of the fixing frame is provided with fixing blocks connected to the pipeline all around;

[0008] An outer frame is arranged on the inner wall of the fixed frame, and the top of the outer frame is in contact with the pipeline, and a filter screen is arranged inside the outer frame;

[0009] The inner walls on both sides of the top and bottom of the outer frame are respectively provided with a placement slot and a groove, and the right sides of the placement slot and the groove are aligned with the filter screen;

[0010] A scraper rod is fitted and connected in the placement groove, a connecting rod is arranged at the bottom of the scraper rod, and the connecting rod passes through the groove and extends to the bottom of the fixing frame;

[0011] A gear rod penetrating the connecting rod is horizontally penetrated through the left bottom of the outer frame.

[0012] As a preferred solution of a central air-conditioning duct filtering mechanism described in the utility model, wherein: the top of the gear rod is meshingly connected with a gear, the gear is set on the rotating shaft, the front end of the rotating shaft passes through the fixed frame and is connected to the output shaft of the motor, and the motor is set on the front side of the fixed frame.

[0013] As a preferred solution of the central air-conditioning duct filtering mechanism described in the utility model, a button electrically connected to the motor is provided on the fixing frame.

[0014] As a preferred solution of the central air-conditioning duct filtering mechanism described in the utility model, a baffle is provided on the rotating shaft.

[0015] As a preferred solution of the central air-conditioning duct filtering mechanism described in the utility model, wherein: the baffle is provided with a support rod in contact with the fixing frame.

[0016] As a preferred solution of the central air-conditioning duct filtering mechanism described in the utility model, a ball handle is provided at the bottom end of the connecting rod.

[0017] Compared with the prior art, the beneficial effect of the utility model is that before removing the fixing frame to take the filter out of the pipe, the gear rod is first moved to the left to not fix the connecting rod. At this time, the rotating shaft drives the baffle to rotate clockwise, so that when the gear rod does not fix the connecting rod, the baffle can cover the left side of the outer frame, and then the connecting rod is pulled downward, so that the dust attached to the left side of the filter scraped off by the scraper rod can be blocked by the baffle and fall into the groove to be collected, so that when the fixing frame is removed from the pipe, the dust attached to the left side of the filter can be prevented from flying around.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] As mentioned in the background art, when the ventilation duct is opened to take out the filter in the prior art, dust often flies around because dust adheres to the surface of the filter, which makes the user experience poor. The utility model provides a central air conditioning duct filter mechanism.

[0024] Example 1
