[0001] The invention belongs to the technical field of ventilation and filtration, and in particular to a ventilation and filtration system for a mushroom cultivation cabin. Background Art

[0002] The growth process of mushrooms has extremely high requirements for air quality. Traditional mushroom cultivation chambers have many deficiencies in ventilation and filtration, such as unsatisfactory air filtration effects, inability to effectively adjust air temperature, humidity and carbon dioxide concentration, etc. These problems have seriously affected the growth quality and yield of mushrooms. Therefore, a ventilation and filtration system is needed to ventilate the cultivation chamber.

[0003] However, the existing ventilation and filtration systems still have drawbacks in actual use: among them, when ventilating the cultivation chamber, the filtering part of the ventilation system cannot be effectively cleaned, which will cause microorganisms to adhere to the pipes, and the filtering components need to be cleaned after long-term use. The existing filtering components are too troublesome to disassemble, which will lead to a longer maintenance time for the entire cultivation chamber.

[0004] The air entering the cultivation chamber needs to be efficiently filtered and purified, and the air temperature, humidity and carbon dioxide concentration need to be adjusted according to the needs of mushroom growth to provide an ideal growth environment for mushrooms, and the filter components need to be able to be cleaned quickly.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention cooperates with structures such as a filter box, a filter hole, and a cleaning fan so that the device can hang up impurities and drop them into the interior of the storage box when the cleaning fan rotates. The storage box still has a dust collection space after the activated carbon filter plate is installed to store dust impurities.

When the entire filter assembly is installed, it is pushed upward so that the arc edge contacts the bottom end of the limit block, and the limit block is squeezed inwardly by the shape of the limit block and the arc edge. After the filter box passes as a whole, the first return spring squeezes the limit block to reset it, so that it is inserted into the empty groove to fix the filter assembly. When disassembling, the transmission block is pressed to drive the top block to move upward. After the top block moves up and contacts the limit block, the limit block is squeezed and contracted again. At this time, the filter assembly can be pulled out, thereby achieving the purpose of facilitating the device to disassemble, clean and replace the filter assembly.

[0022] The invention provides a mounting seat, a transmission rod, a limit plate and other structures to cooperate so that when the device is pressed upward to install the guide filter plate, the limit plate enters the interior of the limit groove and contacts the quick-connect block to squeeze the quick-connect block and the limit rod inward. After the limit plate passes the quick-connect block, the third return spring resets the limit rod and the quick-connect block and limits the limit plate by the quick-connect block. Since the fixing of the limit block can only support the bottom of the filter box, the position of the guide filter plate is fixed by fixing the limit plate, thereby the filter assembly is installed more firmly. When removing, continue to press upward, and after the movable plate moves up and contacts the quick-connect block, the quick-connect block squeezes and lifts the movable plate after passing the movable plate. Since the diameter of the movable plate is larger than the limit plate, the guide filter plate is pulled down as a whole at this time, and the limit plate can be separated from the connection with the quick-connect block, so that the filter assembly can be removed, thereby achieving the purpose of facilitating the device to install the filter assembly more firmly without affecting disassembly.

The fan blades are arranged in three groups and are evenly spaced about the central axis of the cleaning fan 603. The block 604 and the slot 605 are snap-connected.

[0041] The above scheme is adopted: the wind collected into the ventilation duct 1 is guided by the guide groove 8, and the guided wind contacts the cleaning fan 603 to drive the cleaning fan 603 to rotate. When the wind passes through the guide filter plate 5 and the filter hole 602, the filter hole 602 can filter the impurities in the wind, so that the impurities are attached to the inside of the filter box 601. At this time, the cleaning fan 603 can hang down the impurities and drop them into the inside of the storage box 7. After the activated carbon filter plate is installed, the storage box 7 still has dust collection space to store dust impurities.

After opening, the activated carbon filter plate and the collected dust can be cleaned and replaced.

[0042] like Figures 1 to 8 As shown, the first quick-release mechanism 9 includes a limit block 901, a first return spring 902 and an arc edge 903. The limit block 901 is movably connected to the inside of the ventilation duct 1. The first return spring 902 is fixed to the outside of the limit block 901. The limit block 901 and the ventilation duct 1 are slidably connected. The first return spring 902 is provided in several groups, and the first return springs 902 are equidistantly distributed. The first return spring 902 is used to squeeze the limit block 901 and keep it moving toward the bottom of the filter box 601.

[0043] like Figures 1 to 8 As shown, an arc edge 903 is provided at the top of the filter box 601, a grab bar 904 is fixed to the bottom end of the guide filter plate 5, a transmission block 905 is movably connected to the bottom of the guide filter plate 5, a top block 906 is fixed to the top of the transmission block 905, a second return spring structure 907 is fixed to the bottom end of the top block 906, two groups of grab bars 904 are provided, the grab bars 904 are symmetrically distributed about the central axis of the guide filter plate 5, the transmission block 905 and the guide filter plate 5 are slidably connected, two groups of second return spring structures 907 are provided, the second return spring structures 907 are symmetrically distributed about the central axis of the top block 906, the second return spring structure 907 is fixed to the bottom end inside the guide filter plate 5, and the second return spring structure 907 is used to squeeze the top block 906 and keep it moving downward.

[0044] The above scheme is adopted: when the guide filter plate 5 and the filter box 601 are closed, an empty groove is generated between the guide filter plate 5 and the filter box 601. When installing the entire filter assembly, push it upward so that the arc edge 903 contacts the bottom end of the limit block 901, and the limit block 901 is squeezed inward by the shape of the limit block 901 and the arc edge 903. After the filter box 601 passes as a whole, the first return spring 902 squeezes the limit block 901 to reset, so that it is inserted into the empty groove to fix the filter assembly, and when disassembling, press the transmission block 905 to drive the top block 906 to move upward. After the top block 906 moves up and contacts the limit block 901, the limit block 901 is squeezed and contracted again, and the filter assembly is pulled out at this time.

[0045] like Figures 1 to 9 As shown, the second quick release mechanism 10 includes a mounting seat 1001, a transmission rod 1002 and a limit plate 1003. The mounting seat 1001 is fixed to the top of the guide filter plate 5, the top of the mounting seat 1001 is fixed with a transmission rod 1002, the top of the transmission rod 1002 is fixed with a limit plate 1003, the outside of the transmission rod 1002 is movably connected with a movable plate 1004, the inside of the ventilation duct 1 is provided with a limit groove 1005, the inside of the ventilation duct 1 is movably connected with a limit rod 1006, and the outside of the limit rod 1006 is sleeved with The third reset spring 1007, a quick-connect block 1008 is fixed to the outside of the limiting rod 1006, two groups of mounting seats 1001 are arranged, and the mounting seats 1001 are symmetrically distributed about the central axis of the guide filter plate 5. The transmission rod 1002 and the movable disk 1004 are slidably connected, and the diameter of the movable disk 1004 is larger than the diameter of the limiting disk 1003. The limiting rod 1006 and the ventilation duct 1 are slidably connected, and the third reset spring 1007 is used to squeeze the limiting rod 1006 and keep it moving toward the center of the limiting groove 1005.

[0046] Adopting the above scheme: when installing by pressing upward the guide filter plate 5, the limit plate 1003 enters the interior of the limit groove 1005 and contacts the quick-connect block 1008 to squeeze the quick-connect block 1008 and the limit rod 1006 inward. After the limit plate 1003 passes through the quick-connect block 1008, the third reset spring 1007 resets the limit rod 1006 and the quick-connect block 1008, and limits the limit plate 1003 through the quick-connect block 1008. Since the fixing of the limit block 901 can only be applied to the bottom of the filter box 601 It plays a supporting role. By fixing the limit plate 1003, the position of the guide filter plate 5 is fixed, so that the filter assembly is installed more firmly. When removing, continue to press upwards. After the movable plate 1004 moves up and contacts the quick-connect block 1008, the quick-connect block 1008 passes through the movable plate 1004 and squeezes and lifts the movable plate 1004. Since the diameter of the movable plate 1004 is larger than the limit plate 1003, at this time, pulling down the guide filter plate 5 as a whole can disconnect the limit plate 1003 from the quick-connect block 1008.

[0047] The working principle and use process of the present invention are as follows: the wind collected into the ventilation duct 1 is guided by the guide groove 8, and the cleaning fan 603 is driven to rotate after the guided wind contacts the cleaning fan 603. When the wind passes through the guide filter plate 5 and the filter hole 602, the filter hole 602 can filter the impurities in the wind, so that the impurities are attached to the inside of the filter box 601. At this time, the cleaning fan 603 can hang down the impurities and drop them into the inside of the storage box 7. After the activated carbon filter plate is installed, the storage box 7 still has a dust collection space to store dust impurities, and the filter box 601 is rotated and the block 604 cooperates with the slot 605. The guide filter plate 5 and the filter box 601 are closed and opened. After opening, the activated carbon filter plate and the collected dust can be cleaned and replaced. When the guide filter plate 5 and the filter box 601 are closed, an empty slot will be generated between the guide filter plate 5 and the filter box 601. When installing the entire filter assembly, push it upward so that the arc edge 903 contacts the bottom end of the limit block 901, and the shape of the limit block 901 and the arc edge 903 squeeze the limit block 901 to shrink inward. After the filter box 601 passes as a whole, the first return spring 902 squeezes the limit block 901 to return to its original position, so that it is inserted into the empty slot to fix the filter assembly, and when disassembling, press the transmission spring. The movable block 905 drives the top block 906 to move upward, and the top block 906 moves up to contact the limit block 901 and squeezes the limit block 901 again. At this time, the filter assembly is pulled out, and the guide filter plate 5 is pressed upward for installation. The limit plate 1003 enters the interior of the limit groove 1005 and contacts the quick-connect block 1008 to squeeze the quick-connect block 1008 and the limit rod 1006 inward. After the limit plate 1003 passes the quick-connect block 1008, the third reset spring 1007 resets the limit rod 1006 and the quick-connect block 1008, and limits the limit plate 1003 through the quick-connect block 1008. Since the fixing of the limit block 901 can only The bottom of the box 601 serves as a support, and the position of the guide filter plate 5 is fixed by fixing the limit plate 1003, so that the filter assembly is installed more firmly. When removing, continue to press upward, and the movable plate 1004 moves up to contact the quick-connect block 1008, and the quick-connect block 1008 squeezes and lifts the movable plate 1004 after passing through the movable plate 1004. Since the diameter of the movable plate 1004 is larger than the limit plate 1003, at this time, pulling down the guide filter plate 5 as a whole can disconnect the limit plate 1003 from the quick-connect block 1008, thereby ensuring the installation firmness of the filter assembly through two fixing methods, and will not affect the disassembly of the filter assembly.
