[0030] Example: As shown in Figures 1-11, this utility model discloses an embodiment of a portable cleaning device with a foolproof structure, which includes: a portable housing 200 having a vacuum chamber 220 and a leak protection block 288, a flip-top assembly 300 for shielding the vacuum chamber 220, a dust bag assembly connected to the flip-top assembly 300, a vacuum motor located inside the portable housing 200 and downstream of the dust bag assembly, an ejector 600 disposed on the flip-top assembly 300 with one end in contact with the dust bag assembly and the other end in contact with the leak protection block 288, and a swinging member 700 for causing the dust bag assembly to fall off.

[0031] The portable housing 200 includes an air inlet duct 210 at the front end, a vacuum chamber 220 near the air inlet duct 210 for housing a dust bag assembly, a handle 240 at the rear end, a vacuum chamber opening 224 connected at one end to the air inlet duct 210 and at the other end to the vacuum chamber 220, a motor housing 260 located between the vacuum chamber 220 and the handle 240 for housing a vacuum motor, and a dust bag fitting part 280 disposed within the vacuum chamber 220 for engaging with the dust bag assembly and having a dust bag fitting hole 284 and a leak-proof protection block 288. One end of the dust bag fitting hole 284 is connected to the vacuum chamber opening 224, and the other end is connected to the air inlet end of the dust bag assembly. The leak-proof protection block 288 is located above the dust bag fitting hole 284.

[0032] The flip-top assembly 300 includes a dust bag connection module and a rotating cover for fixing the dust bag connection module. The dust bag connection module is located at the front end of the rotating cover, and the rotating cover is used to cover the top of the vacuum chamber 220 and includes a release button 320 at one end, a mounting bracket 340 near and below the release button 320 and having a pair of mounting bracket holes 344, a cover locking hook 360 at the other end, and a sealing cover 380 with one end surrounding the mounting bracket 340 and the other end adjacent to the cover locking hook 360 and sealing the upper end of the vacuum chamber 220. One end of the release button 320 is provided with a locking button protrusion, and the portable housing 200 is provided with a locking hole that mates with the locking button protrusion and a snap-fit ​​groove that mates with the cover locking hook. By unlocking the release button 320, the rotating cover can be detached from the portable housing 200.

[0033] Referring to Figure 11, the dust bag assembly includes a hollow dust bag 400 that can be located within a vacuum chamber 220, and a dust bag fastener 420 located at one end of the dust bag 400 and connected to a dust bag connecting module. The dust bag 400 is a paper bag, cloth bag, or non-woven fabric, and the dust bag fastener 420 is made of plastic or cardboard. In this embodiment, the dust bag fastener 420 is integrally formed with the dust bag 400, but it can also be a separate component.

[0034] The dust bag connection module includes a fixing bracket 500 that at least partially accommodates the dust bag fixing member 420, a pivot member 540 that snaps into or unlocks the dust bag fixing member 420, and a dust bag sealing ring 560 fitted onto the air inlet end of the pivot member 540. The fixing bracket 500 includes a pair of opposing bracket arms 510, each having a bracket arm hole 514; a connecting arm 520 connecting one end of the two bracket arms 510; a receiving space 504 accommodating the pivot member 540 and the dust bag fixing member 420 and defined by the bracket arms 510 and the connecting arm 520; and a pair of fixing bracket side plates 516 extending oppositely from the inner side of the bracket arms 510, wherein the pivot member 540 is deflected relative to the bracket arms 510. The connecting arm 520 is provided with a connecting arm groove 524 accommodating a swing member 700 and a pair of connecting arm holes 526 communicating with both sides of the connecting arm groove 524. The pivot member 540 includes a barb 542 at one end for engaging the dust bag fastener 420, a pivot opening 544 communicating with the interior of the dust bag 400, an operating part 548 at the other end for user operation, and a pair of deflection shafts 546 located between the pivot opening 544 and the operating part 548 and corresponding to the bracket arm hole 514. Under the action of the deflection shafts 546, when the operating part 548 is pressed, the barb 542 unlocks the lock of the dust bag fastener 420. This embodiment also includes a deflection spring disposed between the pivot member 540 and the connecting arm 520. The pivot member 540 includes a pair of elastic covers 549 adjacent to the deflection shafts 546 and housing one end of the deflection spring. Both ends of the deflection shafts 546 are received by the bracket arm holes 514 and generate a deflection action. The gap between the fixed bracket side plate 516 and the pivot member 540 is used to accommodate the dust bag fastener 420.

[0035] The ejector 600 includes a contact end 620 at one end, a locking end 640 at the other end, an ejection pivot 660 located between the contact end 620 and the locking end 640, and an ejection spring disposed at one end on the contact end 620. The distance between the center of the contact end 620 and the center of the ejection pivot 660 is greater than the distance between the center of the locking end 640 and the center of the ejection pivot 660. The two ends of the ejection pivot 660 are correspondingly arranged with the mounting bracket holes 344, thereby enabling rotation about the axis between the contact end 620 and the locking end 640.

[0036] The swing member 700 includes a snap-fit ​​end 720 at one end, a pair of swing shafts 740 at the other end, and a swing member torsion spring sleeved on the swing shafts 740. The snap-fit ​​end 720 is provided with a snap-fit ​​notch 724, and the two swing shafts 740 are provided with a shaft gap 744. The ejector 600 is located below and to one side of the swing member 700. Each swing shaft 740 is correspondingly disposed within a connecting arm hole 526 to generate a rotational motion.

[0037] When installing the dust bag 400, the dust bag fixing member 420 is moved upward until it encounters the contact end 620 and compresses the ejection spring. As a result, the engaging end 640 rotates downward around the ejection pivot 660 and avoids contact with the missing protection block 288. The dust bag fixing member 420 continues to move until it encounters the locking end 720, which forces the locking end 720 to move upward and rotate relative to the swing axis 740, causing the swing member torsion spring to deform.

[0038] When cleaning the dust bag 400, first push the release button 320 to release the lock between the rotating cover and the portable housing 100, and then press the action part 548 to release the latch between the dust bag fixing part 420 and the barb 542. Under the action of the swinging torsion spring and gravity, the snap-fit ​​end 720 will pop the dust bag fixing part 420 and the dust bag 400 downwards and can be thrown into the trash can. The user does not need to directly contact the dust bag fixing part 420 and the dust bag 400, reducing the chance of secondary pollution.

[0039] When the dust bag assembly is missing, the locking end 640 will be reset to a 0-degree angle under the action of the ejection spring. In this state, when the flip cover assembly 300 is installed, the locking end 640 will contact and interfere with the missing protection block 288, causing the flip cover assembly 300 to fail to be installed in place, thus reminding the user that the dust bag has been missing.

[0040] The advantages of this utility model are: it prevents dust bags from being missing, reminds users to install dust bags in a timely manner, and ensures reliable operation.

[0041] The above are merely preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
