The operation is cumbersome and time-consuming. The dust inlet structure is inconvenient to install and difficult to disassemble and clean. As a result, after long-term use, the inside of the vacuum cleaner head will accumulate a lot of dust, which will reduce the vacuuming effect and make it difficult to meet the user's needs for efficient cleaning and convenient maintenance. In order to solve this technical problem, this utility model proposes a handheld vacuum cleaner head structure.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a handheld vacuum cleaner head structure, comprising an outer frame, a storage box inside the outer frame, sliding plates fixedly connected to both side walls of the storage box, sliding grooves on both sides of the outer frame, with the sliding plates slidably connected within the sliding grooves, and a pair of mounting plates fixedly connected to one side of the outer frame, with insertion holes inside the sliding plates, and pins slidably connected between the two mounting plates, with the pins slidably connected within the insertion holes, while the storage box is slidably connected within the outer frame.

[0008] Preferably, an outer shell is fixedly connected to one side of the outer frame, a rotating rod is rotatably connected inside the outer shell, and a cleaning roller is fixedly connected to the middle outer side of the rotating rod. The cleaning roller is rotatably connected inside the outer shell, and a discharge port is opened on one side of the outer shell.

[0009] Preferably, the outer shell is provided with an ash inlet hopper, and the two side walls of the ash inlet hopper are fixedly connected with a card plate, and each card plate has an installation hole inside.

[0010] Preferably, the housing has a pair of slots inside, and a card plate is slidably connected inside the slots. A spring is fixedly connected inside the slots, and a plug is fixedly connected to the other end of the spring.

[0012] Preferably, a connecting pipe is fixedly connected inside the ash hopper, and a dustproof net is fixedly connected inside the connecting pipe.

[0013] (III) Beneficial Effects

[0014] This utility model provides a handheld vacuum cleaner head structure. It has the following beneficial effects:

[0015] (1) The outer frame serves as the main load-bearing structure. The sliding plates on both sides of the internal storage box are embedded in the sliding grooves of the outer frame to form a sliding guide structure. The storage box is fixed by the mounting plate and the pin through the insertion hole to ensure stability during use and easy removal during cleaning. The outer shell is fixed on one side of the outer frame. The motor drives the rotating rod to rotate the cleaning roller. Larger debris is swept by the cleaning roller and sent into the storage box for temporary storage through the discharge port. This design solves the problem of inconvenient garbage cleaning of existing handheld vacuum cleaner heads. This structure actively cleans through the cleaning roller and, together with the pull-out storage box, realizes automatic garbage collection and rapid cleaning, significantly reducing maintenance time and labor costs, and effectively improving the practicality and durability of the handheld vacuum cleaner.

[0016] (2) The plates on both sides of the dust inlet hopper are aligned with the slots on the outer shell and inserted. During the sliding process, the spring is squeezed. When the mounting hole slides to correspond with the plug position, the spring rebounds and pushes the plug to accurately embed into the mounting hole, realizing the quick and stable installation of the dust inlet hopper. After the dust enters through the dust inlet hopper, it is transported through the connecting pipe. The internal dust screen effectively intercepts larger debris and prevents it from entering the connecting pipe and causing blockage. This design solves the problem of cumbersome installation and easy blockage of the existing dust inlet structure of handheld vacuum cleaners. The traditional dust inlet components are complicated to install and disassemble, and lack a filter device. Large particles of debris are easy to accumulate and block the pipe, affecting the vacuuming efficiency. Disassembly and maintenance are more convenient, ensuring that the vacuuming channel is unobstructed and the vacuuming efficiency is significantly improved. At the same time, it is easy to regularly disassemble and clean the dust inlet hopper and dust screen, effectively extending the service life of the vacuum cleaner and reducing maintenance costs.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] Example 1: A handheld vacuum cleaner head structure includes an outer frame 1, a storage box 2 inside the outer frame 1, sliding plates 3 fixedly connected to both side walls of the storage box 2, and sliding grooves 4 on both sides of the outer frame 1, with the sliding plates 3 slidably connected within the grooves 4. A pair of mounting plates 5 are fixedly connected to one side of the outer frame 1, with insertion holes 7 inside the sliding plates 3. A pin 6 is provided between the two mounting plates 5, and the pin 6 slidably connects to the inside of the insertion hole 7. The storage box 2 is slidably connected to the inside of the outer frame 1, and a shell 8 is fixedly connected to one side of the outer frame 1. A rotating rod 9 is rotatably connected inside the outer casing 8, and a cleaning roller 14 is fixedly connected to the outer wall of the middle of the rotating rod 9. The cleaning roller 14 is rotatably connected inside the outer casing 8. A discharge port 16 is opened on one side of the outer casing 8. A motor 10 is fixedly connected to the outer wall of the outer frame 1. A rotating shaft 11 is fixedly connected to the output end of the motor 10. Pulleys 12 are fixedly connected to the outer walls of both the rotating rod 9 and the rotating shaft 11. A belt 13 is provided between the two pulleys 12. At the same time, a bracket 15 is fixedly connected to the outer wall of the outer frame 1, and the rotating shaft 11 is rotatably connected inside the bracket 15.

[0025] After the motor 10 is started, the rotating shaft 11 rotates at high speed under the support of the bracket 15. With the transmission of the belt 13 and the pulley 12, the rotating rod 9 inside the outer casing 8 drives the cleaning roller 14 to rotate synchronously. During the continuous rotation of the cleaning roller 14, the mechanical force generated by its rotation sweeps large pieces of garbage and debris sucked into the outer casing 8 along a specific path to the outer frame 1, and then orderly sends them into the storage bin 2 for temporary storage through the discharge port 16. When the storage bin 2 needs to be cleaned, simply pull the pin 6 out of the insertion hole 7 of the mounting plate 5 and the sliding plate 3, and the sliding plates 3 on both sides of the storage bin 2 can be smoothly pulled out along the sliding groove 4 of the outer frame 1. The whole process does not require complicated disassembly, which greatly simplifies the cleaning process and significantly improves the garbage cleaning efficiency.

[0026] Example 2: The difference between this example and Example 1 is that the outer shell 8 is provided with an ash inlet hopper 17, and the two side walls of the ash inlet hopper 17 are fixedly connected with a card plate 18. Each card plate 18 has an installation hole 19 inside. The outer shell 8 has a pair of card slots 20 inside, and the card plate 18 is slidably connected inside the card slot 20. A spring 21 is fixedly connected inside the card slot 20, and the other end of the spring 21 is fixedly connected with a plug 22, and the plug 22 corresponds to the installation hole 19. At the same time, the plug 22 is slidably connected inside the installation hole 19. A connecting pipe 23 is fixedly connected inside the ash inlet hopper 17, and a dustproof net 24 is fixedly connected inside the connecting pipe 23.

[0027] Dust flows in through the dust inlet 17 and is transported to the vacuum cleaner's interior via the connecting pipe 23. The built-in dust filter 24 acts as a sturdy barrier, intercepting larger debris and effectively preventing blockage of the connecting pipe 23, ensuring unobstructed suction. When installing the dust inlet 17, align the two side plates 18 with the slots 20 on the outer casing 8 and insert them. During insertion, the plates 18 compress the spring 21. When the mounting hole 19 slides to align with the plug 22, the spring 21 quickly rebounds, pushing the plug 22 precisely into the mounting hole 19, achieving a quick and secure installation of the dust inlet 17. This design not only ensures that the dust inlet 17 is not easily loosened during long-term use but also allows for easy disassembly and cleaning by simply unlocking the plug 22, significantly improving vacuum cleaner maintenance efficiency and reducing cleaning time.

[0028] Working principle: When the motor 10 is turned on, the rotating shaft 11 is driven to rotate inside the bracket 15. Through the transmission of the belt 13 and the pulley 12, the rotating rod 9 and the cleaning roller 14 inside the outer shell 8 are driven to rotate synchronously. When the cleaning roller 14 rotates, it sweeps larger debris and foreign objects into the outer frame 1 and into the storage bin 2 through the discharge port 16. The storage bin 2 can be pulled out directly by pulling out the pin 6 from the mounting plate 5 and the insertion hole 7, and is limited in the slide groove 4 by the sliding plate 3, which facilitates cleaning and improves work efficiency. At this time, dust enters through the ash inlet hopper 17 and is transported through the connecting pipe 23. The dustproof net 24 can prevent larger foreign objects from entering the connecting pipe 23 and causing blockage. When the ash inlet hopper 17 is installed, it is inserted into the slot 20 by the clamping plate 18. During the sliding, the spring 21 is squeezed. When the mounting hole 19 slides to the plug 22 position, the spring 21 will push the plug 22 into the mounting hole 19 through the elasticity and quickly fix the ash inlet hopper 17, which is convenient for disassembly and cleaning after long-term use and improves work efficiency.
