[0022] Example: Figure 1-5 As shown, the present invention discloses a specific embodiment of a handheld vacuum cleaner with a detachable dust bag assembly, which includes a body 100 having a motor housing 120, a filter body 130, a battery pack body 140 and a handle 150, a cup body 200 matched with the body, a dust bag assembly 300 detachably arranged in the cup body 200, a motor 400 accommodated in the motor housing 120, a battery pack 500 arranged under the handle 140 and snap-connected to the battery pack body 140, and a filter 600 accommodated in the filter body 130, wherein the dust bag assembly 300 includes a dust bag frame detachably connected to the cup body, and a dust bag 390 detachably connected to the dust bag frame.

[0023] The body 100 includes a motor housing 120 located above the cup body 200, a filter body 130 adjacent to the motor housing 120 and accommodating a filter 600 and located above the handle 150, a battery pack body 140 located below the handle 150, a handle 150 connecting the filter body 130 and the battery pack body 140, and a connecting body located in front of the handle 150 and connecting the filter body 130 and the battery pack body 140, wherein a cavity for a user to hold is formed between the connecting body and the handle 150, the upper end of the connecting body is located between the motor housing 120 and the filter body 130, the lower end of the connecting body is located between the bottom of the cup body and the battery pack body 140, and the connecting body is provided with a button structure for unlocking the cup body 200 near the lower end to disassemble the cup body 200. The motor housing 120 is located above the cup body 200 and accommodates the motor 400, while the filter body 130 is located above the handle 150 and adjacent to the motor housing and accommodates the filter 600. The filter body 130 is provided with an unlocking button 132 so that the filter can be removed for replacement or cleaning.

[0024] The central axis of the cup body 200 is perpendicular to the horizontal plane and has an air inlet pipe 212, and the central axis direction of the air inlet pipe 212 intersects with the extension direction of the handle 150 at an obtuse angle to achieve a gun-style trigger grip. The cup body 200 is small at the upper end and large at the lower end, and there is an inclined transition section 202 between the two. This structure facilitates air intake at the upper end of the dust bag 390 and rapid dust storage at the lower end. A rotatable dust cup bottom cover 220 is provided at the bottom of the cup body 200 to facilitate removal of the dust bag 390 from the bottom for dust cleaning or replacement. The extension direction of the handle 140 passes through the battery pack 500. The cup body 200 is provided with a raised structure that locks with the button structure for locking.

[0025] The dust bag frame includes a fixed portion 320 fixedly connected to the cup body 200, an extension portion 340 connected downward by the fixed portion, a bending portion 360 extending outward from the bottom of the extension portion 340 and arranged corresponding to the transition section 202, and a support portion 380 located at the lower end of the extension portion 340 and in contact with the dust cup bottom cover 220. The fixed portion 320 includes a base plate 321, an air inlet cone 322 protruding downward from the base plate 321 and having a plurality of air inlet meshes, an air inlet hole 324 located outside the air inlet cone 322, and a buckling protrusion 323 arranged on the side and snap-fitted with the cup body 200. The protruding setting of the air inlet cone 322 prevents the dust bag 390 from being blocked at the air inlet of the motor, and at the same time ensures that there is air inlet in both directions, namely, horizontally and vertically. Even if the air inlet cone 322 is blocked, the air inlet hole 324 will not be blocked because it is a distance from the bottom of the air inlet cone 322 in the vertical direction, thereby ensuring the airflow from the dust bag to enter. The extension part 340 is provided with an air inlet 342 located downstream of the air inlet pipe 212, and a cardboard space 344 formed between the extension part 340 and the fixing part 320 to accommodate part of the dust bag. The air inlet 342 is located at the tangential air inlet of the dust bag. A gap is maintained between the support part 380 and the dust bag 390, and a gap is also maintained with the inner wall of the cup body 200 to ensure that the airflow fully flows through the dust bag 390 without being blocked, and the airflow in the cup body 200 is smooth.

[0026] The dust bag 390 is provided with a dust bag clamping plate 392 which can be buckled on the outside of the air inlet hole 342 and has a dust bag opening. The clamping plate space 344 is used to accommodate the dust bag clamping plate 392. The air inlet hole 324 is arranged on the outside of the air inlet cone 322 and away from the air inlet 342, while the air inlet hole 324 is not arranged on the side close to the air inlet 342, so as to reduce the impact of the airflow on the dust bag clamping plate 392 and affect the fixation of the dust bag.

[0027] The motor 400 is preferably a brushless DC motor, but may also be a brushed DC motor. The battery pack 500 is preferably a lithium battery pack, but may also be a nickel-metal hydride battery pack.

[0028] The advantages of the present invention are that dust can be cleaned by regularly replacing the dust bag, thereby reducing secondary pollution, and the user experience is improved by holding the dust bag in a gun-like manner.

[0029] Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
