[0028] In this embodiment, the detector includes a temperature and humidity sensor 5 and a carbon dioxide sensor 6 installed on the inner wall of the storage room 1, which is used to detect the temperature, humidity and carbon dioxide content in the storage room 1 in real time;

[0029] In this embodiment, two ventilation ducts 2 are arranged on the storage room 1, and the two ventilation ducts 2 are respectively installed at the left and right ends of the storage room 1. A fan 3 and a dustproof component 4 are arranged in each ventilation duct 2, so as to facilitate the introduction of external air into the storage room 1 through the two sets of ventilation ducts 2 and the fan 3, and to discharge the turbid air in the storage room 1 to the outside;

[0030] The electrical device in this embodiment is electrically connected to an external controller;

[0031] When in use, the carrot storage rack is placed in the storage room 1, and the carrots to be stored are placed on the storage rack for storage. During the storage of the carrots, the temperature and humidity as well as the carbon dioxide content in the storage room 1 are respectively detected by the temperature and humidity sensor 5 and the carbon dioxide sensor 6. When the temperature and humidity in the storage room 1 exceed the preset values, a fan 3 is controlled to start to introduce external air through a ventilation duct 2, and another fan 3 cooperates with another ventilation duct 2 to lead the air in the storage room 1 to the outside, thereby realizing fast and intelligent ventilation in the storage room 1, so as to adjust the environment in the storage room 1 and make it more convenient for carrot storage.

[0032] like Figures 2 to 5 As shown, the present embodiment also includes a dustproof component 4 disposed in the ventilation duct 2, and the dustproof component 4 includes a dustproof filter 41 installed in the ventilation duct 2 and facing the air inlet end of the fan 3, so as to filter the air flowing in the ventilation duct 2 and reduce the dust and impurities from entering the storage room 1;

[0033] A group of opening and closing plates 42 are respectively arranged at the left and right ends of the dust filter 41, and a fixing frame 43 connected to the inner wall of the ventilation duct 2 is arranged between the dust filter 41 and the opening and closing plates 42 at the right end. Each group of opening and closing plates 42 is composed of a plurality of opening and closing plates 42 distributed at equal intervals, and each opening and closing plate 42 is rotatably connected to the inner side of the ventilation duct 2 through a rotating shaft 48, and the opening and closing plates 42 are horizontally rotated in the ventilation duct 2 to control the on and off of the air in the ventilation duct 2;

[0034] A motor 44 is locked and fixed on the fixing frame 43, and a cleaning brush plate 45 that fits the outer surface of the dust filter 41 is installed on the output shaft of the motor 44. The cleaning brush plate 45 is driven by the motor 44 to rotate to scrape off dust and impurities on the dust filter 41;

[0035] The rotating shaft 48 movably penetrates the top surface of the ventilation duct 2, and the upper end of the rotating shaft 48 movably extends into the inner side of the protective cover 410 locked and fixed on the top surface of the ventilation duct 2, and a crank 49 is fixedly installed on the top of the rotating shaft 48, a slide plate 411 is slidably installed in the protective cover 410, and an electric push rod 413 is installed at the inner rear end of the protective cover 410;

[0036] The slide plate 411 is provided with a plurality of strip-shaped transmission holes 412 corresponding to the cranks 49 one by one. The inner sides of the strip-shaped transmission holes 412 are movably connected to the upper end of the slide plate 411 so as to push the cranks 49 to rotate horizontally through the strip-shaped transmission holes 412.

[0037] The front piston rod of the electric push rod 413 is connected to the top of the slide plate 411, and the slide plate 411 is driven by the electric push rod 413 to move horizontally forward and backward along the inner side of the protective cover 410, so as to drive the strip-shaped transmission hole 412 to move horizontally, and finally the strip-shaped transmission hole 412 drives the crank 49 to rotate horizontally;

[0038] In this embodiment, two discharge ports 47 are provided on the bottom end surface of the ventilation duct 2. The two discharge ports 47 are located between the left and right opposite surfaces of the two sets of opening and closing plates 42, and the two discharge ports 47 are respectively located at the lower left end and the lower right end of the dust filter 41. The two discharge ports 47 are connected to the inner side of the collecting frame 46 locked and fixed at the bottom of the ventilation duct 2. The two discharge ports 47 are used to discharge dust and impurities scraped off the dust filter 41 to the outside;

[0039] In this embodiment, two symmetrical cleaning brush plates 45 are installed on the motor 44. The two cleaning brush plates 45 are respectively attached to the left and right end surfaces of the dust filter 41, so as to more comprehensively clean the dust and impurities on the dust filter 41.

[0040] In this embodiment, the crank 49 is an L-shaped structure, and the part of the crank 49 that is movably connected to the inner side of the strip-shaped transmission hole 412 is cylindrical, so that the strip-shaped transmission hole 412 can more stably push the crank 49 to rotate;

[0041] The outer diameter of the upper end of the crank 49 is smaller than the inner length of the strip-shaped transmission hole 412, so that the upper end of the crank 49 can move in the strip-shaped transmission hole 412.

This is a prior art and will not be described in detail.

[0043] The electrical device in this embodiment is electrically connected to the external controller;

[0044] When in use, when air flows in the ventilation duct 2, the air is filtered by the dust filter 41 to prevent dust impurities from carrying too much dust into the storage chamber 1. When the dust impurities on the dust filter 41 need to be cleaned, the electric push rod 413 can be controlled to drive the slide plate 411 and the strip transmission hole 412 to move horizontally. The strip transmission hole 412 drives the crank 49 to rotate during the horizontal movement. The crank 49 drives the opening and closing plate 42 to rotate inward by driving the rotating shaft 48. When two adjacent opening and closing plates 42 are attached to each other, the dust filter 41 is sealed in cooperation with the ventilation duct 2.

[0045] Then, the motor 44 is started to drive the cleaning brush plate 45 to rotate and scrape off the dust impurities on the dust filter 41. The scraped dust impurities fall downward through the discharge port 47 and enter the collection frame 46 for storage, so as to realize fast and intelligent cleaning of the dust impurities on the dust filter 41 and reduce the workload of manual cleaning of impurities.
