DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 , Figure 2 and Figure 4 , the utility model provides a technical solution: a refrigeration device with an air inlet dust removal structure, comprising: a casing 1, a supporting mechanism 2, a cooling unit 3 and an exhaust net 4;

[0025] A supporting mechanism 2 is provided in the casing 1, and a cooling unit 3 and an exhaust net 4 are provided in the supporting mechanism 2; an air inlet pipe 5 is fixedly passed through one side of the casing 1, an inlet fan 6 is connected to the inner wall of the inlet pipe 5, a dustproof net 7 is provided on one side of the inlet fan 6, a dust removal mechanism 8 is provided in the inlet pipe 5, and an evaporator 9 is provided on one side of the casing 1.

[0026] The dust removal mechanism 8 includes: a connecting rod 801, a driving motor 802, a vertical plate 803, a bolt 804, a spring 805, a rotating shaft 806, a cleaning brush 807, a first end toothed disc 808 and a second end toothed disc 809. The connecting rod 801 is connected to the inner wall of the air inlet pipe 5, the end of the connecting rod 801 is connected to the driving motor 802, the vertical plate 803 is connected to the inner wall of the air inlet pipe 5 near the connecting rod 801, and a bolt 804 is connected to one side of the vertical plate 803. The bolt 804 penetrates and is slidably connected in the dustproof net 7, and the outer side of the bolt 804 abuts against Spring 805, spring 805 abuts against one side of the dustproof net 7, the output end of the driving motor 802 is connected with a rotating shaft 806, the rotating shaft 806 passes through the inner wall of the rotating dustproof net 7 and is connected with a cleaning brush 807, the cleaning brush 807 abuts against one side of the dustproof net 7, the side of the dustproof net 7 away from the cleaning brush 807 is fixedly connected with a first end toothed disc 808, the rotating shaft 806 passes through and is rotatably connected in the first end toothed disc 808, one side of the first end toothed disc 808 is meshedly connected with a second end toothed disc 809, and the second end toothed disc 809 is sleeved and fixed on the outer side of the rotating shaft 806.

[0027] During the specific implementation, the driving motor 802 is started to drive the rotating shaft 806 to rotate, and the rotating shaft 806 drives the cleaning brush 807 to rotate to clean one side of the dustproof net 7 to sweep away the adsorbed dust. The rotating shaft 806 is installed with the cleaning brush 807 through screws and can be disassembled. At the same time, the rotating shaft 806 drives the second end toothed disc 809 to rotate. Since the first end toothed disc 808 is fixed to the dustproof net 7, and the dustproof net 7 is fixed by the vertical plate 803 and the bolt 804 and cannot rotate, the teeth of the second end toothed disc 809 slide out from between the teeth in the first end toothed disc 808, pushing the dustproof net 7 along the screw. The bolt 804 slides and squeezes the spring 805. Only the end of the bolt 804 has a part of thread to prevent the dust net 7 from sliding. When the teeth of the second-end toothed disc 809 slide into between the other two teeth in the first-end toothed disc 808, the spring 805 pushes the dust net 7 to reset, driving the first-end toothed disc 808 and the second-end toothed disc 809 to abut and mesh together. This is repeated continuously, and the dust net 7 vibrates back and forth continuously. While the cleaning brush 807 cleans the dust net 7, the dust net 7 vibrates to shake off the dust, which allows the fan 6 to reverse and blow back the dust net 7 to blow off the dust and remove the dust from the air inlet.

[0028] See also Figure 1 , Figure 3 and Figure 4It can be seen that the supporting mechanism 2 includes: a support plate 201, an L-shaped baffle plate 202, a pulley 203, a limiting groove 204, a limiting rod 205, a hook 206 and a buckle 207. The support plate 201 is slidably connected in the casing 1, a cooling unit 3 is installed above the support plate 201, and an L-shaped baffle plate 202 is fixedly connected to one side of the support plate 201, an exhaust net 4 is connected in the L-shaped baffle plate 202, and a pulley 203 is connected to the bottom of the L-shaped baffle plate 202. Limiting grooves 204 are provided at the front and rear of the inner wall of the casing 1, and limiting rods 205 are slidably connected in the limiting grooves 204. The limiting rod 205 is connected to the front and rear of the support plate 201, and a hook 206 is connected to the upper surface of the L-shaped baffle plate 202. A buckle 207 is engaged on the hook 206, and the buckle 207 is connected to the upper surface of the casing 1.

[0029] During specific implementation, the buckle 207 is pulled to be removed from the hook 206 to release the fixation of the casing 1 and the L-shaped baffle 202, and then the L-shaped baffle 202 is pulled to drive the pulley 203 to slide. The pulley 203 supports the L-shaped baffle 202 to balance the force and prevent tilting. The support plate 201 is pulled outward to drive the limiting rod 205 to slide in the limiting groove 204 to prevent the support plate 201 from falling off from the casing 1 and exposing the cooling unit 3 to the outside. Compared with maintenance in a smaller space in the casing 1, it is more convenient.

[0030] To sum up: when using this refrigeration equipment with an air inlet dust removal structure, first, the evaporator 9 is installed indoors, and the rest is installed outdoors. The compressor in the cooling unit 3 compresses the refrigerant to make it become a high-pressure gas, and then releases heat through the condenser to become a high-pressure liquid, and then expands and reduces the pressure through the expansion valve to become a low-pressure liquid, and enters the evaporator 9, where it absorbs external heat and evaporates into a low-pressure gas for refrigeration. When the device is overhauled, the buckle 207 is removed from the hook 206, and the L-shaped baffle 202 is pulled to expose the cooling unit 3 to the outside for maintenance. The drive motor 802 is started to drive the cleaning brush 807 to clean the dust net 7, while the dust net 7 vibrates to remove dust. The contents not described in detail in this description belong to the prior art known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
