[0028] See also Figure 1-3 The utility model provides a technical solution: an airflow suction type dustproof water dispenser cooling fan assembly, comprising:

[0029] The fan bracket 1 has multiple chambers separated by mesh panels, the inner side of which is positioned on the heat-conducting fin group at the heat-generating end of the cold end of the water dispenser. The positioning ring 3 extending from the outer side of the chamber is assembled on the inner side of the rear cover 4 of the water dispenser. The rear cover 4 is provided with a plurality of first mesh panels 5 and second mesh panels 6 from the inside to the outside. The edge of the first mesh panel 5 matches the inner circle of the positioning ring 3. An intermediate cavity 7 is formed between the first mesh panel 5 and the second mesh panel 6. Filler is arranged in the intermediate cavity 7. A dust screen 8 is detachably provided on the outer side of the second mesh panel 6.

[0030] The fan body 2 includes a plurality of drive motors and turbines respectively arranged in the chamber, and the turbines are connected to the output shafts of the drive motors.

[0031] The dustproof net 8 is an 80-mesh net to ensure the filtering performance of the dustproof net to prevent dust from penetrating into the air inlet end of the water dispenser - the rear cover 4, thereby polluting the internal environment of the water dispenser.

[0032] The dust-proof net 8 is arranged on the inner side of the mounting plate 9, and a ventilation grid 10 with a size smaller than that of the dust-proof net 8 is set on the mounting plate 9. The mounting plate 9 is inserted and positioned on the mounting bracket 11 on the outer side of the rear cover plate 4 from top to bottom, so that after the mounting plate 9 is inserted and positioned on the mounting bracket 11, the dust-proof net 8 can be fully spread out to ensure the air intake filtering effect and the air intake quality at the first mesh plate 5.

[0033] The mounting frame 11 includes side panels arranged on both sides of the dustproof net 8, and a number of limit blocks 12 extend inward from the outer side of the side panels. The distance between the limit blocks 12 and the rear cover plate 4 is equal to the sum of the thicknesses of the dustproof net 8 and the mounting plate 9, so that the limit blocks 12 press the mounting plate 9 after positioning it, thereby making the dustproof net 8 close to the second mesh plate 6, preventing dust from penetrating from the gaps between the flow structures and affecting the quality of air purification.

[0034] A stopper is extended inwardly from the bottom of the side plate, and limiting ears 13 are extended outwardly from both sides of the top of the mounting plate 9. The limiting ears 13 abut against the top of the side plate.

[0035] The mounting plate 9 is also provided with a gripper 14 to facilitate the grabbing, disassembling and assembly of the mounting plate 9 .

[0036] The working principle of the air suction type dustproof cooling fan assembly of the water dispenser of this embodiment includes the following: when in use, the driving motor drives the turbine to rotate, so that an airflow from the outside to the inside is formed at the rear cover plate 4, so as to inhale the air outside the water dispenser directly into the fan assembly. During this period, the secondary air intake is purified and sound-absorbing through the dustproof net 8 and the filler, so as to ensure the quality of the airflow entering the water dispenser and the low-noise operation of the above-mentioned structure. The airflow flows through the ventilation grid 10, the dustproof net 8, the second mesh plate 6, the filler, and the first mesh plate 5 in sequence, and enters the fan assembly through the positioning ring 3, through which the air is guided to the heat-conducting fin group for heat absorption, and is laterally conducted out and discharged from the air outlet end of the water dispenser, so as to realize efficient heat dissipation of the heat-generating end of the cooling chamber, so as to ensure the cooling effect of the cooling chamber on drinking water and the internal heat dissipation of the water dispenser and efficient operation of the components.

[0037] In summary, due to the adoption of the above technical solution, the airflow suction type dustproof water dispenser cooling fan assembly of this embodiment has the following beneficial effects compared with the prior art:

[0038] This utility model directly and tightly connects the fan bracket to the heat-conducting fin group and rear cover at the heat-generating end of the water dispenser's cooling tube, and sets a first mesh plate corresponding to the positioning ring on the rear cover to ensure that the airflow entering the water dispenser fully flows to the heat-conducting fin group, ensuring heat dissipation efficiency. The filler and dust screen ensure efficient purification of the incoming air and noise reduction during operation of the water dispenser. The dust screen is detachably assembled via the mounting plate and mounting bracket for easy cleaning. This ensures the cooling efficiency of the cooling tube while achieving dust-proof effects on the machine.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
