Description

Technical Field

[0001] This utility model relates to the field of disinfection cabinet technology, specifically a disinfection cabinet with a detachable filter structure. Background Technology

[0002] A disinfection cabinet is a tool that uses ultraviolet rays, far-infrared rays, high temperature, ozone, and other methods to dry, sterilize, disinfect, keep warm, and dehumidify items such as tableware, towels, clothing, beauty and hairdressing tools, and medical devices. The disinfection cabinet is an electrical product invented and pioneered in China, and is widely used in hotels, restaurants, schools, military units, canteens, and other places.

[0003] A search revealed a disinfection cabinet disclosed in Chinese Patent Publication No. CN212790216U. The key technical points are: a self-priming pump draws air from inside the disinfection cabinet into the purification chamber; a motor drives a rotating rod to rotate, which in turn drives a driving bevel gear to rotate, causing a driven bevel gear to rotate, which in turn drives a screw to rotate. This causes a cleaning brush to clean the surface of the first filter screen, preventing clogging. The cleaned dust falls into a conveying pipe. The rotating rod drives a driving sprocket to rotate, which in turn drives a driven sprocket via a chain, thereby driving an auger to rotate and output the dust through an output pipe.

[0004] However, in the prior art, the cleaning brush used to clean the first filter screen for a long time results in the cleaning brush carrying a large amount of dust and dirt. In order to solve the problem that the dust carried by the cleaning brush affects the cleaning of the filter screen, this application proposes to place the filter screen on the connecting groove by a slider, pull the round hole filter plate to remove the connecting groove from the disinfection cabinet, and pull the handle on the filter screen to quickly disassemble the filter screen, thereby facilitating the cleaning of the filter screen. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the above-mentioned background technology, there are shortcomings and defects in the existing technology, such as the cleaning brush carrying dust affecting the cleaning of the filter screen.

[0006] The disinfection cabinet with a detachable filter structure disclosed in this utility model includes a cabinet body, a cabinet door, and a rear cover. The rear cover is provided with a perforated filter plate, the perforated filter plate is provided with a filter plate handle and a limiting block, the limiting block is provided with a connecting rod, the connecting rod is fitted with a spring, the connecting rod is provided with a fixing plate, the spring is provided with a limiting paddle, the perforated filter plate is provided with a connecting groove on one side, the connecting groove is provided with a filter assembly, one end of the connecting groove is provided with a docking groove, and the docking groove is provided with a ventilation assembly.

[0007] Furthermore, the filtration assembly includes an activated carbon filter and an air filter, both of which are equipped with sliders. The connecting groove is provided with a sliding groove, and the activated carbon filter and the air filter are slidably connected to the connecting groove.

[0008] Furthermore, the ventilation assembly includes an exhaust fan and a rotating motor. The rotating motor is equipped with a rotating rod, and the rotating rod is equipped with a bevel gear. There are two bevel gears that mesh with each other, and another bevel gear is fixedly connected to the exhaust fan.

[0009] Furthermore, the cabinet is provided with an air inlet and an air outlet, the air inlet is provided with a dustproof screen, the activated carbon filter is provided with a cleaning brush on its sliding groove, and both the activated carbon filter and the air filter are provided with handles.

[0010] Furthermore, the connecting groove is square in shape, one end of the connecting groove is fixedly connected to the round hole filter plate, and the other end is slidably connected to the docking groove, and the back cover is fixedly connected to the cabinet.

[0011] Furthermore, one end of the limiting block is fixedly connected to the connecting rod, and the other end is fixedly connected to the limiting lever. A fixing plate is fixedly connected to the connecting rod, and the fixing plate is fixedly connected to the rear cover. A groove is provided on the rear cover for the limiting lever to move up and down.

[0012] Furthermore, the docking groove is square in shape, and there are two exhaust fans and two rotating motors, with the exhaust fans fixedly connected to the docking groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up components such as limit blocks and springs, allows for easy and quick disassembly of the filter screen when it is disassembled. By pushing the limit plate upward, the limit plate moves the connecting rod upward, which in turn moves the limit block upward and compresses the spring until the limit block moves out of the groove of the round hole filter plate. Pulling the filter plate handle then pulls the round hole filter plate and the docking groove out of the back cover. Pulling the handle removes the required filter screen, achieving the effect of easy and quick disassembly and easy cleaning of the filter screen.

[0015] 2. This utility model is equipped with components such as an exhaust fan and a rotating motor. When the power of the disinfection cabinet is turned on, the rotating motor is driven to rotate. The rotating motor drives the rotating rod to rotate, and the rotating rod drives the bevel gears to rotate. The bevel gears drive the exhaust fan to draw in air, which filters and purifies the dust and odor gases inside the cabinet through the activated carbon filter and the air filter. Finally, the air is discharged through the round hole filter plate, which accelerates the air circulation inside the disinfection cabinet and filters out the harmful gases discharged from the disinfection cabinet.
