TECHNICAL FIELD

[0001] The present application relates to the field of household appliances, in particular to a main machine of a dust collection device with heat dissipation function and application thereof. BACKGROUND

[0002] As a cleaning tool, the dust collector, mop, and washing and separating all-in-one machine have become indispensable appliances in people's daily life. Among them, the wireless handheld dust collector is more widely applicable due to its advantages of self-contained battery, small size, and convenient carrying and use, and thus is loved by the public. Generally, the handheld dust collector integrates the motor, dust-gas separation device, and other components at the place operated by the hand. If the layout of the entire handheld dust collector is improper, it will cause the operator to be laborious and inconvenient to operate when using, and at the same time, it will also affect the performance of the dust collector itself.

[0029] Figure 2 for Figure 1 This is a schematic diagram of the internal structure of a vacuum cleaner main unit with heat dissipation function.

[0030] Figure 3 for Figure 1 This is a schematic diagram of the main unit of a vacuum cleaner with heat dissipation function from another angle. Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Figures 1 to 3 The diagram schematically shows the main unit of a vacuum cleaner with a heat dissipation function according to one embodiment of the present invention. As shown, the device includes a main body 1, a filter structure 2, an exhaust structure 5, and a handheld structure 3.

[0033] The filter structure 2 has an air inlet 211 at one end and is connected to the exhaust structure 5 at the other end. The handheld structure 3 houses a battery pack 4 and is connected to the exhaust structure 5. The exhaust structure 5 is located on the main body 1 and is used to exhaust the air filtered by the filter structure 2.

[0034] The exhaust structure 5 continuously expels air from the main unit, creating negative pressure inside. This causes the other end of the filter structure 2 to continuously draw in dirt. After the dirt is filtered by the filter structure 2, the clean air is expelled through the exhaust structure 5, thus completing the entire cleaning process. The battery pack 4 powers the main unit and is generally separated from the exhaust structure 5.

[0035] The inventor finds that the battery generates heat during use of the host, which will affect the service life of the host to some extent if not discharged in time. The hand-held structure 3 provided with the battery pack 4 is communicated with the air exhaust structure 5, and the air in the hand-held structure 3 is communicated with the air exhaust structure 5. When the air exhaust structure 5 works, negative pressure is formed in the air exhaust structure 5, and when the air filtered by the filtering structure 2 is discharged, the air in the hand-held structure 3 is also driven to flow, and some air filtered by the filtering structure 2 also enters the hand-held structure 3, and the air in the hand-held structure 3 is further discharged, so that the air in the hand-held structure 3 becomes flowing air and is continuously entered, circulated and discharged. When the host is started, the flowing air in the hand-held structure 3 is in heat exchange with the battery pack 4 all the time, the heat emitted by the battery pack 4 is taken away, and is discharged out of the host through the air exhaust structure 5, so that the host can be effectively cooled, the damage to the battery is reduced, the aging of the host is reduced, the service life of the host is greatly prolonged, the use cost is saved, and resources are saved.

[0036] The filtering structure 2 comprises a dust cup 21, a filter screen 22 and a cyclone cone 23. One end of the dust cup 21 is provided with an air inlet 211, the air inlet 211 is connected with a rolling brush structure of the dust collector, and garbage cleaned by the rolling brush enters the filtering structure 2 through the air inlet 211. The dust cup 21 further comprises a dust collecting part 212, and the dirt cleaned after multiple filtering enters the dust collecting part 212 of the dust cup 21 for collection, and the dust collecting part 212 can be emptied when full, which is convenient to handle.

[0037] The filter screen 22 is arranged at one end of the cyclone cone 23, and the dust cup 21 and the cyclone cone 23 are connected in communication through the filter screen 22; and the cyclone cone 23 is connected in communication with the air exhaust structure 5. Thus, the dirt sucked in is filtered through the filter screen 22, large particles or residues after filtering enter the dust cup 21 and are collected, and clean air after filtering enters the cyclone cone 23 and further enters the air exhaust structure 5.

[0038] Specifically, the cyclone cone 23 comprises a plurality of conical parts 231, the plurality of conical parts 231 are arranged in a ring shape, one end of the conical part 231 is connected in communication with the filter screen 22, and the other end of the conical part 231 is connected in communication with the air exhaust duct 51. The conical part 231 can uniformly discharge gas, and when the conical part 231 rotates, fine dust will slide along the inner wall of the conical part 231 to the conical opening 232 and further fall into the dust cup 21 for collection, and the air will continue to pass through the cylindrical passage to enter the air exhaust duct 51 and the hand-held structure 3.

[0039] The hand-held structure 3 comprises a handle 31, a first connecting part 32 and a second connecting part 33. One end of the first connecting part 32 is connected with the main body 1, the other end of the first connecting part 32 is connected with one end of the second connecting part 33, one end of the handle 31 is connected with the main body 1, the other end of the handle 31 is connected with the other end of the second connecting part 33.

The design of the hand-held structure can make the whole inside of the hand-held structure 3 communicated, and the cold air can enter the second connecting part 33 through the handle 31 and the first connecting part 32, and exchange with the air in the second connecting part 33, so as to effectively cool the battery pack 4.

[0040] Of course, in some embodiments, only one of the handle 31 and the first connecting part 32 can be connected with the second connecting part 33, but it is ensured that the structure with the battery pack 4 is communicated with the air exhaust structure 5.

[0041] The battery pack 4 is located on the second connecting part 33, and the battery pack 4 is arranged opposite to the main body 1, which is convenient for the balance of the whole main machine, especially when the main machine works, it is convenient for hand-holding and more labor-saving.

[0045] The air in the air exhaust duct 51 is further filtered by the Hepa 6 and then enters the air exhaust cavity 55. The motor 53 drives the air exhaust fan 54 to rotate, constantly sucking the air in the air exhaust duct 51 into the air exhaust cavity 55, and constantly taking the air in the air exhaust cavity 55 out and exhausting it to the outside of the main machine through the air exhaust port 52.
