[0045] See also Figure 1-5 The present invention provides a technical solution: a vacuum cleaner with efficient heat dissipation of a battery pack, comprising:

[0046] The vacuum cleaner main unit 1 includes an inner main unit housing 11, a negative pressure motor 12, and an outer main unit housing 13. The inner main unit housing 11 is provided with a first air outlet mesh 111 at the air outlet end of the negative pressure motor 12. The first air outlet mesh 111 is connected to the total air outlet mesh at the top of the vacuum cleaner main unit 1 and the second air outlet mesh 113 on the side.

[0047] The dust cup 2 is connected to the bottom of the vacuum cleaner main unit 1, and its inner cavity is connected to the main unit air inlet mesh 131;

[0048] The handle assembly 3 is mounted on the side of the vacuum cleaner main body 1 and the dust cup 2, and is provided with a battery pack air inlet 32 ​​that is plugged into the second air outlet assembly 133. The first ventilation hole 135 on the third air outlet assembly 134 is connected to the mounting slot 31 and is used for air flow in and out.

[0049] The battery pack 4 includes a battery pack housing 41 and a battery pack 42 therein. A battery pack air outlet 412 is provided on a side of the battery pack housing 41. The battery pack air inlet 32 ​​communicates with the interior of the battery pack housing 41. The battery pack side panels 422 on the battery pack 42 are disposed within the mounting slots 31.

[0050] The air inlet assembly 5 is arranged at the air inlet end of the dust cup 2.

[0051] The present invention diverts the clean airflow discharged from the negative pressure motor after filtering by the dust cup filter assembly. Part of it is discharged from the vacuum cleaner through the main air outlet mesh, part of it enters the battery pack through secondary filtration, and is fully heat-transferred and discharged from the battery pack air outlet. Part of it is cooled by air showers on the battery pack side panels in the installation slot or other electrical devices that are relatively less affected by the airflow quality, and is discharged from the vacuum cleaner, thereby achieving full heat dissipation of each type of battery pack accessories, ensuring its long-term and efficient operation and corresponding cleaning and filtering quality.

[0052] An annular filter 112 is provided on the outside of the first air outlet mesh 111, and the clean airflow discharged from the negative pressure motor 12 is subjected to secondary filtration based on the dust cup 2 filter assembly, thereby improving the air outlet quality and reducing the interference of the electrical components in the battery pack 4 that are greatly affected by the airflow quality during the air shower cooling of the battery pack 4, thereby ensuring the heat dissipation efficiency while avoiding the performance and quality loss of the electrical components.

[0053] The third air outlet mesh 115, the ventilation port of the second air outlet component 133, and the first ventilation hole 135 are all waist-shaped holes. The first air outlet component 114 and the second air outlet component 133 are arranged horizontally, and the first ventilation hole 135 is arranged vertically and a partition is arranged in the middle. Through this design, a large flow of air with low wind speed loss is ensured while realizing the dual function of air inlet and outlet of the first ventilation hole 135.

[0054] The second air outlet assembly 133 and the third air outlet assembly 134 are arranged on the mounting seat 132, and the mounting groove 31 is plugged into the mounting seat 132 and positioned by bolts or pins to ensure the docking stability of the guide structure and the stability of the air flow on the surface and inside of the battery pack.

[0055] The side of the battery pack shell 41 is provided with a plurality of through holes 411 connecting its inner cavity and the battery pack air inlet 32. The length of the arrangement range of the plurality of through holes 411 is greater than the width of the battery pack 42, ensuring that the clean air flow range of the secondary filtration fully covers the battery pack 42 and ensures efficient heat dissipation.

[0056] A battery pack substrate is provided at the bottom of the battery pack 42, and the connector 421 of the battery pack side panel 422 is inserted into the positioning hole 413 of the battery pack shell 41 and docked with the connector 421 of the battery pack substrate, thereby ensuring the stability of positioning and electrical docking when the electrical components of the battery pack are arranged on the inner and outer surfaces of the battery pack shell 41 according to their types.

[0057] The operating principle of a vacuum cleaner with efficient battery pack heat dissipation in this embodiment includes the following: During use, the dust-laden airflow collected by the air inlet assembly is filtered by the filter assembly in the dust cup 2. The filtered airflow enters the vacuum cleaner main unit 1 through the main unit air inlet mesh 131. The negative pressure motor 12 directs the airflow, causing part of it to flow out of the first air outlet mesh 111. After secondary filtration by the annular filter 112, the airflow is split, with part of it flowing out of the main air outlet mesh and part of it flowing through the second air outlet mesh 113, the second air outlet assembly 133, the battery pack air inlet 32, and the through hole 411, transferring heat and dissipating heat to the battery pack 42. The airflow finally exits the vacuum cleaner through the battery pack air outlet 412. The remaining airflow from the negative pressure motor 12 flows into the third air outlet mesh 115, dissipating heat to the battery pack side panel 422 in the mounting slot 31 or other electrical components that are relatively less affected by the airflow quality, and then exits the vacuum cleaner. This achieves efficient heat dissipation of the battery pack's electrical components by type, ensuring efficient operation.

[0058] Example 2:

[0059] See also Figure 2 、 6 -8. On the basis of the above-mentioned embodiment 1, based on the full heat dissipation design of the electrical components of the battery pack according to the classification, the air inlet air flow parameters of the vacuum cleaner are measured to make more precise adjustments to the negative pressure motor 12 and other operating parameters of the vacuum cleaner to ensure low energy consumption and efficient operation of dust collection and separation of the vacuum cleaner. Preferably, the first air outlet component 114 is arranged at the recess 116, and a second ventilation hole 136 connected to the recess 116 is provided at the bottom of the outer main body shell 13. The second ventilation hole 136 is connected to the upper annular air duct 137, and a lower annular air duct 21 is provided on the top edge of the dust cup 2. The upper annular air duct 137 is sealed and spliced ​​with the lower annular air duct 21, and a third ventilation hole 22 extends from the side of the lower annular air duct 21.

[0060] The air inlet assembly 5 includes an inner air inlet tube 51 with an inner air cavity and an outer air inlet tube 52 positioned on the inner air inlet tube 51. An air inlet probe 53 extending into the inner air cavity is provided on the inner air inlet tube 51. An outer air cavity is formed between the inner air inlet tube 51 and the outer air inlet tube 52. The outer air cavity is connected to the third ventilation hole 22 and the fourth ventilation hole 541 of the fourth air outlet assembly 54.

[0061] The working principle of a vacuum cleaner with efficient heat dissipation of a battery pack in this embodiment includes: through the above-mentioned structural design, the air inlet probe 53 can measure the airflow parameters such as dust particle size and quantity of the dust-laden airflow collected in the inner air cavity of the air inlet inner tube 51, and at the same time, the clean airflow discharged from the third air outlet mesh 115 flows through the second ventilation hole 136, the upper and lower annular air ducts, the third ventilation hole 22, and the outer air cavity between the air inlet inner tube 51 and the air inlet outer tube 52 in sequence, and the clean airflow introduced into the air inlet probe is zero-point corrected. The zero-point correction can be carried out by automatic fixed frequency, variable frequency control or manual control to ensure the test accuracy. The airflow is finally discharged from the vacuum cleaner from the fourth ventilation hole 541 of the fourth air outlet component 54.

[0062] In summary, due to the adoption of the above technical solution, the vacuum cleaner with efficient heat dissipation of the battery pack of this embodiment has the following beneficial effects compared with the prior art:

[0063] 1. The present invention diverts the clean airflow discharged from the negative pressure motor after filtering by the dust cup filter assembly. Part of it is discharged from the vacuum cleaner through the main air outlet mesh, part of it enters the battery pack through secondary filtration, and is fully heat-transferred and discharged from the battery pack air outlet. Part of it is cooled by air showers on the battery pack side panels in the installation slot or other electrical devices that are relatively less affected by the airflow quality, and is then discharged from the vacuum cleaner, thereby achieving full heat dissipation of various accessories of the battery pack according to their types, ensuring its long-term and efficient operation and corresponding cleaning and filtration quality.

Based on the battery pack's fully heat-dissipating design based on the type of electrical components, the vacuum cleaner's inlet airflow parameters are measured to more precisely adjust the negative pressure motor and other vacuum cleaner operating parameters, ensuring the vacuum cleaner's low energy consumption and efficient dust collection and separation. Specifically, the air inlet probe can measure airflow parameters such as dust particle size and quantity in the dust-laden airflow collected in the air cavity within the inner air inlet tube. At the same time, the clean airflow discharged from the third air outlet mesh sequentially flows through the second ventilation hole, the upper and lower annular air ducts, the third ventilation hole, and the outer air cavity between the inner and outer air inlet tubes. The clean airflow entering the air inlet probe is zero-calibrated to ensure test accuracy. The airflow finally exits the vacuum cleaner through the fourth ventilation hole of the fourth air outlet assembly.
