[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. By setting up multiple groups of air intake chambers and multiple groups of side filter cottons to filter the air intake holes, foreign matter or floating objects can be prevented from blocking the air intake during the air inhalation process, so that the device has the advantage of anti-blocking.

[0038] The filter housing 4 is provided with a sealing cover 5 on its upper side. The sealing cover 5 is provided with a discharge mechanism 6. The discharge mechanism 6 extracts the filtered air from the filter housing 4 to complete the delivery of the filtered air.

[0039] A positioning mechanism 7 is provided inside the filter housing 4, and the positioning mechanism 7 is used to position filter elements of different sizes and multiple groups of the same size, thereby facilitating the positioning and removal of multiple groups of filter elements, thereby reducing the difficulty of removing and replacing the filter elements;

[0040] A dust collecting mechanism 8 is provided directly below the positioning mechanism 7. The dust collecting mechanism 8 cleans the interior of the filter element according to the anti-blocking requirement, thereby preventing the cleaned dust from being retained in the interior of the filter element, thereby extending the service life of the filter element.

[0041] In this embodiment, the discharge mechanism 6 includes an exhaust hood body 61, an air outlet 62, an outer isolation seat 63, a motor 64, an exhaust hole 65, an internal threaded tube 66, a fan blade 67 and a drive shaft 68. The exhaust hood body 61 is arranged directly above the sealing cover 5. The exhaust hood body 61 is provided with an outer isolation seat 63. The outer side of the outer isolation seat 63 is connected to the motor 64. The output end of the motor 64 is connected to the drive shaft 68. The outer side of the drive shaft 68 is connected to the fan blade 67. The outer side of the drive shaft 68 is connected to the internal threaded tube 66. The top of the sealing cover 5 is provided with exhaust holes 65 at equal intervals.

[0042] In this embodiment, the exhaust hood 61 is connected to the outside of the motor 64 through an outer isolation seat 63 provided at the bottom end, and the outside air is sucked in through the motor 64 and filtered through the filter element 74.

[0043] In this embodiment, the motor 64 is nested with the internal threaded tube 66 through the drive shaft 68 connected to the output end, and the drive shaft 68, the internal threaded tube 66 and the outer side of the external threaded rod 85 are connected to facilitate driving the brush plate 84 to rotate and clean.

[0044] In this embodiment, the positioning mechanism 7 includes a filter element bracket 71, a positioning hole 72, a groove seat 73, a filter element 74 and a side filter cotton 75. The outer side of the filter element bracket 71 is provided with a positioning hole 72 in a ring shape, the outer side of the filter element bracket 71 is provided with a groove seat 73, the outer side of the groove seat 73 is connected to the side filter cotton 75, the filter element bracket 71 is symmetrically arranged on the upper and lower sides of the filter element 74, and the filter element bracket 71 is arranged inside the filter housing 4.

[0045] In this embodiment, the filter element bracket 71 is connected to both sides of the side filter cotton 75 through a groove seat 73 arranged on the outside.

[0046] In this embodiment, the dust collecting mechanism 8 includes a dust collecting tray 81, a transmission shaft 82, a fan-shaped tray 83, a brush plate 84, an external threaded rod 85 and a fastener 86. The dust collecting tray 81 is arranged at the bottom end of the filter element bracket 71, and the bottom end bearing of the dust collecting tray 81 is connected to the transmission shaft 82. The fan-shaped tray 83 is symmetrically arranged on the outer side of the transmission shaft 82. The outer side of the fan-shaped tray 83 is fitted with a brush plate 84. The outer side of the dust collecting tray 81 is annularly penetrated by a fastener 86. The transmission shaft 82 and the fan-shaped tray 83 are arranged inside the filter element 74, and the fan-shaped tray 83 is used to clean the outer side of the filter element 74.

[0047] In this embodiment, the transmission shaft 82 is connected to the outer side of the internal threaded tube 66 via an external threaded rod 85 disposed at the top. The external threaded rod 85 is used to connect the outer side of the internal threaded tube 66 to facilitate the transfer and disassembly of the equipment.

[0048] In this embodiment, the base 1 is connected to the output end of the battery 10 through an electric heating plate 9 disposed inside, and the electric heating plate 9 is used to perform cyclic heating on the inside of the device to dry the device.

[0049] The practical application of this anti-blocking air filter includes the following working processes:

[0050] Step 1: The operator first removes the sealing cover 5 from the top of the filter housing 4, then takes the filter element bracket 71 from the inside of the filter housing 4, and then sequentially installs multiple groups of side filter cottons 75 on the outside of the groove seat 73 for connection, and then fits the two sides of the filter element 74 with the filter element bracket 71 arranged on the upper and lower sides, inserts the screws into the inside of the positioning hole 72, and locks the filter element bracket 71 and the outside of the filter element 74, and at the same time, uses the groove seat 73 distributed in an annular manner on the outside of the filter element bracket 71 to fit the upper and lower sides of the side filter cotton 75;

[0051] Step 2: The operator installs the filter element bracket 71 and the filter element 74 inside the filter housing 4, and then fits the side filter cotton 75 arranged on the outside of the filter element bracket 71 to the outside of the air inlet holes 3 arranged at equal intervals on the outside of the air inlet chamber 2. When the motor 64 drives the fan blades 67 to rotate, the outside air is filtered through the air inlet holes 3 arranged on one side and then injected into the inside of the filter element 74. The filter element 74 is used to guide the filtered air into the inside of the exhaust cover body 61 through the exhaust holes 65 arranged at the top;

[0052] Step 3: Use the air outlet 62 opened on the outside of the exhaust cover 61 to discharge the filtered air. The operator can also nest the pipe fittings on the outside of the exhaust cover 61 to discharge the filtered air to other places. The operator can also turn on the battery 10 to use the battery 10 to provide power for the electric heating plate 9, and use the electric heating plate 9 to heat the base 1 and the inside of the filter housing 4 to dry the filter element 74 and the side filter cotton 75 after filtering;

[0053] Step 4: When it is necessary to clean the filter element 74 disposed inside the filter element bracket 71, the operator first separates the sealing cover 5 disposed on the top of the filter housing 4, and connects the drive shaft 68 connected to the output end of the motor 64, so that the internal threaded tube 66 connected to the bottom end of the drive shaft 68 is connected to the outer side of the external threaded rod 85. When the motor 64 drives the drive shaft 68 to rotate, the drive shaft 68 drives the fan-shaped disc 83 to rotate, and the fan-shaped disc 83 drives the brush plate 84 to select, and the brush plate 84 is used to clean the inside of the filter element 74;

[0054] Step 5: At the same time, dust continuously falls into the dust collecting disc 81. The operator disassembles and separates the fastener 86 penetrating the bottom end of the dust collecting disc 81 from the bottom end of the filter element bracket 71 of another group, and guides out the cleaned dust. Then, the high-speed rotating fan blades 67 are used to remove dust from the surface of the filter element 74 and the side filter cotton 75. During normal operation, the outside air first passes through the side filter cotton 75 to filter the air dust to prevent dust from being trapped in the air intake chamber 2 and the air intake hole 3.

[0055] Step 6: After cleaning the outside of the filter element 74 inside the filter housing 4, disassemble the connection between the external threaded rod 85 and the internal threaded tube 66. During normal use, when the motor 64 drives the fan blades 67 to rotate, it will no longer drive the transmission shaft 82 and the fan-shaped disk 83 to rotate. The operator connects the fastener 86 arranged in an annular manner on the outside of the dust collecting disk 81 to the bottom end of the filter element bracket 71, and then seals the top of the dust collecting disk 81 to prevent the dust set inside the filter element 74 from falling into the inside of the filter housing 4.

[0056] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
