[0024] like Figures 1 to 3 As shown, the present invention provides a first embodiment of a handheld vacuum cleaner with an air inlet pipe, which includes a main body 1000, a dust cup 2000 detachably mounted on the main body 1000 and having a dust cup cavity 2020, a motor housing 3000 with one end connected to one end of the dust cup 2000, and a motor 3200 located in the motor housing 3000 and downstream of the dust cup 2000.

[0025] The main body 1000 includes a guide body 1200, an air inlet pipe 1300 located within the guide body 1200 and connected to the input end of the dust cup 2000, a handle body 1400 for supporting the motor housing body 3000, a support body 1600 located at one end of the handle body 1400 and near the air inlet pipe 1300, a power supply body 1800 connected at one end to the bottom of the support body 1600 and at the other end to the bottom of the handle body 1400, and a battery 4000 located within the power supply body 1800. A positioning device is provided between the dust cup 2000 and the guide body 1200. The guide body 1200 includes an air inlet at the front end and a body positioning hole 1022 at the top, wherein the air inlet is connected to the input end of the air inlet pipe 1300. The air inlet 1300 includes an air inlet 1320 at one end, an air inlet positioning hole 1322 at the top and near the air inlet 1320, and an air inlet outlet 1324 at the other end.

[0026] The dust cup 2000 includes a dust cup locking button 2040 at the top, a dust cup cover 2042 located at the front end of the dust cup 2000 and one end of which cooperates with the dust cup locking button 2040 to open and seal the dust cup cavity 2020, and a cyclone mesh assembly 2200 located inside the dust cup cavity 2020 for cyclone dust removal. The positioning device includes a first dust cup positioning block 2060 located at the bottom of the dust cup 2000 and fixed in place with the air inlet pipe positioning hole 1322, and a second dust cup positioning block 2062 adjacent to the first dust cup positioning block 2060 and fixed in place with the body positioning hole 1022. The cross-sectional area of ​​the air inlet pipe positioning hole 1322 is smaller than the cross-sectional area of ​​the body positioning hole 1022, and the second dust cup positioning block 2062 is located between the first dust cup positioning block 2060 and the motor 3200. The air inlet direction of the air inlet pipe 1300 is parallel to the center direction of the dust cup 2000, and the center direction of the dust cup 2000 passes through the center of the motor 3200.

[0027] This embodiment also includes a display screen 3600 disposed at the other end of the motor housing 3000, wherein the center direction of the dust cup 2000 passes through the display screen 3600; and the display screen 3600 is tilted relative to the center direction of the dust cup 2000.

[0028] like Figure 4-5As shown, this utility model also provides a second embodiment of a handheld vacuum cleaner, which includes a vacuum cleaner main unit 100, a connecting pipe 200 with one end connected to the input end of a guide body 1200, and a floor brush 300 connected to the other end of the connecting pipe 200 and capable of reciprocating motion on a horizontal plane. The vacuum cleaner main unit 100 includes a main body 1000, a dust cup 2000 detachably mounted on the main body 1000 and having a dust cup cavity 2020, a motor housing body 3000 with one end connected to one end of the dust cup 2000, and a motor 3200 located within the motor housing body 3000 and downstream of the dust cup 2000.

[0029] During operation, the floor brush 300 moves across the surface to be cleaned. Dirty airflow enters the vacuum cleaner main unit 100 through the connecting pipe 200, then flows in through the air inlet 1320 and out through the air outlet 1324 into the dust cup chamber 2020. There, cyclone separation occurs within the dust cup 2020. The separated airflow then enters the cyclone mesh assembly 2200, then the motor 3200, and finally is discharged into the atmosphere. Because an independent air inlet pipe 1300 is installed inside the air guide body 1200, airflow leakage is prevented, reducing air volume loss. Simultaneously, the air inlet pipe positioning hole 1322 coordinates with the positioning of the first dust cup positioning block 2060, and the main body positioning hole 1022 coordinates with the fixed second dust cup positioning block 2062. The two dust cup positioning blocks have different shapes and sizes, facilitating dust cup positioning and easy detachment.

[0030] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
