[0027] Example: Figure 1-3 As shown, the utility model discloses a first embodiment of a portable vacuum cleaner, which includes: a handle body 100 with a cavity therein, a dust cup body 200 connected to one end of the handle body 100 and having a cyclone chamber 210 and a dust collecting chamber 220, a mesh cover portion 300 at least partially disposed in the cyclone chamber 210, and a motor located in the cavity and downstream of the mesh cover portion 300, wherein the dust cup body 200 includes an air inlet 202 located at the front end, a cyclone side wall 214 for separating the cyclone chamber 210 and the dust collecting chamber 220, and a dust cup cover 240 for shielding one end of the cyclone chamber 210 and the dust collecting chamber 220, wherein the central direction of the cyclone chamber 210 is perpendicular to the central direction of the motor.

[0028] The handle body 100 further includes a switch 120 disposed at the top, and a battery pack 160 connected to the other end thereof and supplying power to the motor.

[0029] The dust cup body 200 includes an air inlet duct 204 connected to the air inlet port 202 at one end, and a spiral guide portion 212 connected to the other end of the air inlet duct 204 and located in the cyclone chamber 210. The bottom of the dust cup 200 is a horizontal plane and can be placed on a horizontal plane. The cyclone chamber 210 is located between the dust collecting chamber 220 and the handle body 100.

[0030] The mesh cover 300 is detachably arranged, and its center direction coincides with the center direction of the cyclone chamber 210, wherein the dust cup cover 240 has an opening that allows the mesh cover 300 to pass through. The mesh cover 300 includes a filter screen 320 having a plurality of filter holes and located in the cyclone chamber 210, and a top cover 340 connected to the top of the filter screen 320 and exposed to the outside, and the cross-sectional area of ​​the top cover 340 is larger than the opening of the dust cup cover 240.

[0031] During operation, the dust-laden airflow enters the air inlet duct 204 from the air inlet 202, and moves upward in a spiral under the guidance of the spiral guide part 212, that is, the air inlet direction and the cyclone direction are perpendicular to each other; large dust and garbage enter the dust collecting chamber 220 through the dust collecting port on the top of the cyclone side wall 214, and the airflow enters the interior of the mesh cover part 300 through the filter 320 of the mesh cover part 300 in the cyclone chamber 210, then downwardly enters the motor, and is then discharged into the atmosphere.

[0032] like Figure 4-5 As shown, the utility model discloses a second embodiment of a portable vacuum cleaner, which includes: a handle body 100 with a cavity therein, a dust cup body 2100 connected to one end of the handle body 100 and having an air inlet 2102 and a cyclone chamber 2120, a mesh cover portion 3100 at least partially disposed in the cyclone chamber 2120, and a motor located in the cavity and downstream of the mesh cover portion 3100, wherein the central direction of the cyclone chamber 2120 is perpendicular to the central direction of the motor. The handle body of this embodiment has the same structure as the first embodiment, and only the dust cup body is different. In this embodiment, the cyclone chamber and the dust collection chamber are combined, but the cyclone direction and the air inlet direction are still perpendicular to each other.

[0033] like Figure 6-7 As shown, the utility model discloses a third embodiment of a portable vacuum cleaner, which comprises: a handle body 100 having a cavity therein, a dust cup body 2200 connected to one end of the handle body 100 and having a cyclone cavity 2210 and a dust collecting cavity 2220, a primary filter 3200 at least partially disposed in the cyclone cavity 2210, and a motor located in the cavity and downstream of the primary filter 3200. The handle body 100 is provided with a motor air inlet cavity 140 at the front end of the motor.

[0034] The dust cup body 200 includes an air inlet 2202 at the front end, an air outlet 2204 at the rear end and connected to the motor air inlet chamber 140, an ash drop port 2212 for connecting the cyclone chamber 2210 and the dust collecting chamber 2220, and a dust cup cover 2240 for shielding the cyclone chamber 2210 and one end of the dust collecting chamber 2220, wherein the center direction of the cyclone chamber 2210 is perpendicular to the center direction of the motor. The dust collecting chamber 2220 is located between the cyclone chamber 2210 and the handle body 100. The ash drop port 2212 is higher than the air inlet 2202 along the center direction of the cyclone chamber 2210. Since the dust collecting chamber 2220 is located outside the cyclone chamber 2210, the dust in the dust collecting chamber 2220 will not interfere with the filtering of the primary filter 3200, thereby improving the cyclone performance.

[0035] This embodiment further includes a secondary filter 3400 located in the dust collecting chamber 2220, downstream of the primary filter 3200 and upstream of the motor.

[0036] The dust cup cover 2240 includes an internally hollow dust cup cover cavity 2242 and a connecting channel located in the dust cup cover cavity 2242 and connecting the primary filter 3200 and the secondary filter 3400 , wherein the primary filter 3200 or the secondary filter 3400 is at least partially inserted into the dust cup cover cavity 2242 .

[0037] During operation, the dust-laden airflow enters the cyclone chamber 2210 from the air inlet 2202 and moves upward in a spiral, that is, the air inlet direction and the cyclone direction are perpendicular to each other; large dust and garbage enter the dust collecting chamber 2220 through the dust outlet 2212, and the airflow enters the interior through the filter screen of the first-level filter 3200 in the cyclone chamber 2210, and then goes upward into the connecting channel, and then goes downward into the second-level filter 3400. A second cyclone is performed in the second-level filter 3400, and the dust falls to the bottom, while the airflow goes upward and then downward into the air outlet 2204, and then enters the motor air inlet chamber 140, thereby entering the motor, and finally discharged into the atmosphere.

[0038] The utility model has the advantages of: adopting cyclone filtration in a direction perpendicular to the air inlet, being more conducive to dust and gas separation, preventing dust from directly blocking the mesh cover, improving filtration performance and ensuring reliable operation.

[0039] The above are only preferred implementations of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can make several modifications and improvements without departing from the creative concept of the present utility model, which should be included in the protection scope of the present utility model.
