[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0030] See also Figure 1-5 The present invention provides a technical solution: an air inlet structure for a refrigeration device with a self-cleaning function, comprising an air inlet pipe 1, a support rod 3 is fixedly connected to the rear side of the inner wall of the air inlet pipe 1, a drive motor 2 is fixedly connected to the inner end of the support rod 3, a fan blade 4 is fixedly connected to the output end of the drive motor 2, a filter plate 5 is movably inserted into the inner wall of the air inlet pipe 1, a fixing ring 6 is arranged on the front side of the filter plate 5, a sliding groove 21 is opened on the front side of the fixing ring 6, an outer surface of the fixing ring 6 is fixedly connected to the inner wall of the air inlet pipe 1, an outer toothed ring 7 is arranged on the front side of the fixing ring 6, and a sliding member 22 is fixedly connected to the back side of the outer toothed ring 7, The sliding member 22 is slidably connected to the sliding groove 21, the teeth of the outer gear ring 7 do not contact the inner wall of the air inlet pipe 1, and a brush plate 8 is movably embedded inside the outer gear ring 7. The brush on the back of the brush plate 8 contacts the front of the filter plate 5. A transmission motor 10 is fixedly connected to the right side of the air inlet pipe 1, and a transmission gear 11 is fixedly connected to the output end of the transmission motor 10. The transmission gear 11 passes through the right side of the air inlet pipe 1, and the transmission gear 11 is meshed with the outer gear ring 7. A dust outlet groove 12 that passes through from top to bottom is provided on the front side of the lower surface of the air inlet pipe 1, and the dust outlet groove 12 is located below the inner side of the filter plate 5 and the fixing ring 6.
[0031] In the present invention, in order to facilitate the staff to disassemble and assemble the brush plate 8, the brush plate 8 is fixedly connected to the outer gear ring 7 by a first screw 9, and two groups of first screws 9 are provided. The staff can release the fixation between the brush plate 8 and the outer gear ring 7 by unscrewing the two groups of first screws 9 out of the inside of the brush plate 8, and vice versa, they can be fixed, which facilitates the staff to disassemble and assemble the brush plate 8.
[0032] In the present invention, in order to prevent larger impurities from entering the interior of the air inlet duct 1, a dust blocking net 13 is fixedly connected to the frontmost side of the inner wall of the air inlet duct 1. The dust blocking net 13 can effectively intercept larger impurities in the outside air and prevent larger impurities from entering the interior of the air inlet duct 1.
[0033] In the present invention, in order to improve the overall aesthetics of the device, a shell 14 is provided on the right side of the air inlet pipe 1, and the shell 14 is connected to the air inlet pipe 1 by a second screw 15. The transmission motor 10 and the transmission gear 11 are both located inside the shell 14. Because the shell 14 covers the outside of the transmission motor 10 and the transmission gear 11, the transmission motor 10 and the transmission gear 11 are prevented from being directly exposed to the outside, thereby improving the overall aesthetics of the device.
[0034] In the present invention, in order to achieve the function of dissipating heat for the transmission motor 10, a heat dissipation groove 16 that runs through the left and right sides is opened on the right side of the shell 14. Due to the setting of the heat dissipation groove 16, the heat generated by the transmission motor 10 inside the shell 14 during operation can be discharged through the heat dissipation groove 16, thereby achieving the function of dissipating heat for the transmission motor 10.
[0035] In the present invention, in order to facilitate the staff to disassemble and assemble the baffle 17 and the air inlet duct 1, a baffle 17 is slidably connected to the front side of the upper surface of the air inlet duct 1, and the baffle 17 is connected to the air inlet duct 1 by a third screw 18. The staff controls a designated tool to screw the third screw 18 upward out of the interior of the air inlet duct 1, so as to release the fixation between the baffle 17 and the air inlet duct 1. At this point, the baffle 17 can be disassembled, and vice versa, it can be reinstalled, which facilitates the staff to disassemble and assemble the baffle 17 and the air inlet duct 1.
[0036] In the present invention, in order to facilitate the staff to pull the filter plate 5 upward out of the air inlet pipe 1, a hand buckle groove 19 is opened on the rear side of the inner wall of the bottom of the air inlet pipe 1, and two groups of hand buckle grooves 19 are provided. The two groups of hand buckle grooves 19 are respectively located at the front and rear sides of the top of the filter plate 5. The staff inserts their fingers into the inside of the hand buckle groove 19, and then tightly pinches the top of the filter plate 5, and then pulls it upward to pull the filter plate 5 out of the air inlet pipe 1, which is convenient for the staff to pull the filter plate 5 upward out of the air inlet pipe 1;
[0037] Because the filter plate 5 is detachable, filter plates 5 of different specifications can be installed into the air inlet duct 1 according to needs during production of the product, thereby improving the applicability of the device.
[0038] In the present invention, in order to facilitate the staff to take out the disassembled brush plate 8 from the inside of the air inlet pipe 1, or put a new brush plate 8 into the inside of the air inlet pipe 1, and then install it, a through groove 20 is opened on the front side of the inner wall of the bottom of the air inlet pipe 1. The setting of the through groove 20 facilitates the staff to put their palms into the inside of the air inlet pipe 1, and facilitates the staff to take out the disassembled brush plate 8 from the inside of the air inlet pipe 1, or put a new brush plate 8 into the inside of the air inlet pipe 1, and then install it;
[0039] Because the brush plate 8 is detachable, when the product is produced, brush plates 8 of different specifications can be installed inside the air inlet pipe 1 according to work requirements, thereby improving applicability.
[0040] In the present invention, in order to facilitate the rotation of the transmission gear 11 along the inside of the air inlet pipe 1, a rotation groove running through the left and right is opened on the right side of the air inlet pipe 1, and the inner diameter of the rotation groove is larger than one tenth of the outer diameter of the transmission gear 11. Because the outer diameter of the rotation groove is larger than one tenth of the outer diameter of the transmission gear 11, the outer side surface of the transmission gear 11 will not rub against the inner wall of the air inlet pipe 1, which facilitates the rotation of the transmission gear 11 along the inside of the air inlet pipe 1.
[0041] In the present invention, in order to improve the stability of the connection between the support rod 3 and the drive motor 2, a reinforcement ring is fixedly sleeved on the inner side of the outer surface of the support rod 3, and the inner side surface of the reinforcement ring is fixedly connected to the outer side surface of the drive motor 2. The reinforcement ring increases the connection area between the inner end of the support rod 3 and the outer side surface of the drive motor 2, improves the stability of the connection between the support rod 3 and the drive motor 2, and can effectively prevent the connection between the inner end of the support rod 3 and the outer side surface of the drive motor 2 from breaking.
[0042] The air inlet structure of the refrigeration equipment with self-cleaning function can indirectly drive the outer gear ring 7 and the brush plate 8 to rotate through the transmission motor 10, so that the brush plate 8 can sweep the dust and impurities intercepted on the surface of the filter plate 5, so that the dust will fall downward and finally be discharged from the inside of the air inlet pipe 1 through the dust outlet groove 12. At the same time, part of those fluffy impurities will be discharged through the dust outlet groove 12, and the remaining part will be brushed away by the brush plate 8, so that it will be entangled on the brush of the brush plate 8. At this point, the dust and impurities on the filter plate 5 are automatically cleaned, and the filter plate 5 will not be blocked, thereby ensuring the smoothness of the air intake of the air inlet pipe 1.
[0043] The air inlet structure for refrigeration equipment with a self-cleaning function can discharge the heat generated by the transmission motor 10 through the arrangement of the heat dissipation slot 16, thereby realizing the function of dissipating heat for the transmission motor 10 and preventing the temperature inside the housing 14 from continuously rising when the transmission motor 10 is running;
[0044] By unscrewing the third screw 18, the fixation between the baffle 17 and the air inlet pipe 1 is released, and then the baffle 17 is removed to remove the obstruction of the hand buckle groove 19 and the through groove 20. Then, the staff member inserts his fingers into the hand buckle groove 19 to pinch the top of the filter plate 5, and then pulls it upward out of the air inlet pipe 1, which is convenient for replacing the filter plate 5 damaged due to long-term use. Then, the staff member inserts his palm into the air inlet pipe 1 through the through groove 20, takes out the disassembled brush plate 8, and then installs the new filter plate 5, which is convenient for the staff member's operation.
[0045] The air inlet structure of the refrigeration equipment with a self-cleaning function can effectively intercept larger impurities in the outside air through the dust blocking net 13, preventing larger impurities from entering the interior of the air inlet pipe 1, and can effectively filter the gas entering the interior of the air inlet pipe 1 through the filter plate 5, thereby effectively intercepting dust and impurities in the gas and preventing a large amount of dust and impurities from finally entering the interior of the refrigeration equipment.
[0046] When the refrigeration device is in use, the output end of the driving motor 2 drives the fan blades 4 to rotate and absorbs air from the outside. During this process, the dust screen 13 can intercept larger impurities to prevent them from entering the air inlet pipe 1. Then, the filter plate 5 can intercept smaller dust and impurities to achieve effective filtration of the air and prevent a large amount of dust and impurities from entering the interior of the refrigeration device.
[0047] After a long time, a large amount of dust and impurities will adhere to the front of the filter plate 5. Therefore, the user needs to clean the dust and impurities on its surface, and then turn off the refrigeration equipment to stop the drive motor 2 and the fan blades 4. Then the user starts the transmission motor 10. The output end of the transmission motor 10 drives the transmission gear 11 to rotate along the inside of the rotating groove. The transmission gear 11 is in meshing state with the outer gear ring 7. Therefore, the outer gear ring 7 can be driven to rotate at the same time, and the outer gear ring 7 drives the brush plate 8 and the sliding member 22 to rotate. At the same time, the sliding member 22 rotates along the inside of the sliding groove 21. When the brush plate 8 rotates, the brush on the brush plate 8 sweeps the dust and impurities attached to the front of the filter plate 5, so that the dust slowly falls down and is finally discharged from the inside of the air inlet 1 through the dust outlet groove 12. At the same time, part of the fluffy impurities will be discharged by the dust outlet groove 12, and part will be entangled on the brush until the dust and impurities attached to the front of the filter plate 5 are cleaned. Then, the transmission motor 10 is turned off to stop the rotation of the outer gear ring 7 and the brush plate 8. At this point, the dust and impurities on the front of the filter plate 5 are automatically cleaned.
[0048] When the filter plate 5 and the brush plate 8 are damaged due to a long period of time, the staff can control the designated tool to screw the third screw 18 until the third screw 18 is screwed upward out of the air inlet pipe 1, thereby releasing the fixation between the air inlet pipe 1 and the baffle 17, and then sliding the baffle 17 horizontally to release the blocking of the hand buckle groove 19 and the through groove 20. Then the staff's fingers penetrate into the hand buckle groove 19, tightly pinch the top of the filter plate 5, and then pull it upward out of the air inlet pipe 1 to complete the removal of the filter plate 5, and then reinsert the new filter plate 5 into the air inlet pipe 1 to complete the replacement of the filter plate 5. Then the staff uses the designated The tool screws the first set of first screws 9 upward out of the inside of the brush plate 8, and then the staff controls the outer gear ring 7 to rotate, so that the second set of first screws 9 at the bottom are rotated to the top, and then screwed upward out of the inside of the brush plate 8, so far, the fixation between the outer gear ring 7 and the brush plate 8 is released, and then the staff's palm goes deep into the inside of the air inlet pipe 1 through the through groove 20 to take out the damaged brush plate 8, so far, the disassembly of the brush plate 8 is completed, and conversely, the new brush plate 8 can be reinstalled inside the outer gear ring 7, and then the baffle 17 and the air inlet pipe 1 are reconnected, so far, the replacement of the damaged filter plate 5 and the brush plate 8 is completed;
[0049] When the transmission motor 10 is damaged, the staff uses a designated tool to unscrew the second screw 15 to release the connection between the outer shell 14 and the air inlet pipe 1, and then removes the outer shell 14 to expose the transmission motor 10. The staff can then repair it and reinstall the outer shell 14 on the air inlet pipe 1 after the repair.
[0050] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.
[0051] The sizes and shapes of all components in this structure are not specifically limited here and need to be produced according to actual conditions.
[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
