[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] This handheld vacuum cleaner, such as Figures 1-4 As shown, the working suction head 1 and the fan chamber 2 provide suction to the working suction head 1, enabling it to pick up dust from the ground and collect it in the dust collector 3 through the conduit 15. The working suction head 1 includes two dust rollers 4, which are designed to effectively gather dust and debris from the ground, making them easier to remove. Collection boxes 5 are bolted to both sides of the working suction head 1 along the width of the two dust rollers 4. An operating lever 6 is detachably connected to the side wall of the collection box 5. A through groove 14 is provided on the side wall of the working suction head 1, the width of which is the same as the diameter of the operating lever 6. The through groove 14 allows the operating lever 6 near the conduit 15 to pass through the working suction head 1, facilitating operator use. A cutting blade 7 and several cleaners 8 are integrally formed on the side wall of the operating lever 6. The angle between the cutting blade 7 and the cleaners 8 is 60°. The cleaners 8 are designed as hooks, which can better engage the dust rollers. 4. Cleaning: When the working nozzle 1 is cleaning dust and garbage on the ground, if the two dust rollers 4 are stuck due to hair entanglement, the operator applies a pulling force to the operating lever 6 to detach the operating lever 6 from the side wall of the storage box 5. Rotate the operating lever 6 and apply a pushing force to cut the hair entangled on the two dust rollers 4 with the cutting blade 7. Then rotate the operating lever 6 again and use the cleaner 8 to scrape over the dust rollers 4 to clean the hair on the dust rollers 4. The hair can be temporarily held on the cleaner 8. The cleaner 8 can carry the hair into the storage box 5 to clean the hair. The angle between the cutting blade 7 and the cleaner 8 ensures that the use of the cleaner 8 and the cutting blade 7 will not interfere with each other. If the angle is too large, the size of the opening of the storage box 5 needs to be increased, which increases the probability that the hair stored in the storage box 5 will fall out of the storage box 5. The several cleaners 8 located on the two operating levers 6 are staggered so that the two operating levers 6 will not get stuck and unable to rotate when used at the same time.

[0021] like Figures 3-4As shown, the length of the cutting blade 7 is less than the length of the inner cavity of the storage box 5, and the distance between the cleaners 8 located at both ends of the same operating rod 6 is less than the length of the inner cavity of the storage box 5, so that the cutting blade 7 and the several cleaners 8 located on the same operating rod 6 can be stored in the storage box 5. The length of the operating rod 6 is greater than the length of the storage box 5, and both ends of the operating rod 6 extend out of the storage box 5 to facilitate the operator's operation of the operating rod 6. The operating rod 6 is detachably connected to the storage box 5 through a clamping assembly. When not in use, the operating rod 6 is stored in the storage box 5 through the clamping assembly. When needed, the operating rod 6 can be removed from the clamping assembly for use.

[0022] like Figures 4-6 As shown, the clamping assembly includes an integrally formed receiving box 9 and a U-shaped clamping plate 10. One end of the clamping plate 10 is connected to the inner wall of the receiving box 9. The width of the opening end of the clamping plate 10 is smaller than the width of its other end, and the opening of the clamping plate 10 is smaller than the diameter of the operating rod 6, so that the operating rod 6 can be fixed in the clamping plate 10. The clamping plate 10 has elastic deformation properties, and the gap between the receiving box 9 and the clamping plate 10 provides space for the deformation of the clamping plate 10. When the operating rod 6 needs to be used, the operator applies a pulling force to the operating rod 6. The operating lever 6 moves toward the opening of the clamping plate 10. At this time, the two side walls of the clamping plate 10 are pushed outward, making the opening of the clamping plate 10 larger, so that the operating lever 6 can be removed from the clamping plate 10 for use. Rollers 11 are rotatably connected to both ends of the clamping plate 10 near the opening. The rollers 11 are made of rubber. The rollers 11 can reduce the size of the opening of the clamping plate 10 when it is engaged, reducing the probability of the operating lever 6 falling out. On the other hand, they can save effort when removing and inserting the operating lever 6.

[0023] like Figures 4-6As shown, elastic elements 12 are rotatably connected to the inner walls at both ends of the inner cavity of the storage box 5 along its length. The elastic elements 12 are coil springs. One end of the elastic element 12 away from its fixed point with the storage box 5 is fixedly connected to one end of the operating rod 6 along its length via a connecting rope 13. Both ends of the connecting rope 13 are fused to the elastic element 12 and the operating rod 6, respectively. The connecting rope 13 prevents the operating rod 6 from being lost. When the operating rod 6 is used, the pulling force is transmitted to the elastic element 12 through the connecting rope 13, causing the elastic element 12 to stretch. After use, the elastic element 12 retracts, storing the connecting rope 13 within it. The connection rope 13 allows the rotation of the operating lever 6 to be unrestricted. The length of the connection rope 13 is greater than the distance between the clamping plate 10 and the two dust rollers 4. The length of the connection rope 13 is sufficient to prevent the elastic element 12 from being pulled out of the storage box 5 when the operating lever 6 is located between the two dust rollers 4, thus affecting the use of the operating lever 6. The distance between the elastic element 12 and the bottom surface of the storage box 5 is greater than the distance between the elastic element 12 and the top surface of the storage box 5. Since the operating lever 6 is fixed at the bottom of the storage box 5, setting the elastic element 12 at a higher position can reduce the impact of hair brought into the storage box 5 by the operating lever 6 on the elastic element 12.

[0024] Working principle: When the two dust rollers 4 in the working suction head 1 are tangled with hair and cannot rotate, the operator applies a pulling force to the operating lever 6. The operating lever 6 and the roller 11 apply a pushing force to the two side walls of the clamping plate 10, causing the opening of the clamping plate 10 to widen enough for the operating lever 6 to be removed. The operator moves the operating lever 6 between the two dust rollers 4 and rotates the operating lever 6 so that the cutting blade 7 on the operating lever 6 can cut the hair tangled on the two dust rollers 4. After cutting, the operator rotates the operating lever 6 again to use the cleaner 8 on the operating lever 6 to scrape off the hair on the dust rollers 4, and then inserts the operating lever 6 with hair into the clamping plate 10 for fixation, so that the hair is collected in the collection box 5.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
