Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a handle device with an easily assembled power supply and a portable dust removal device thereof. Background Technology

[0002] In everyday cleaning scenarios, portable dust removal devices are widely used due to their flexible operation and strong applicability. As a core component of human-computer interaction, the handle device not only needs to meet the requirements of comfortable grip, but also needs to provide stable power support for the device. The ease of installation and connection reliability of the built-in power supply directly affect the overall user experience of the device.

[0003] The power compartment opening of the handle of most existing portable dust removal devices is located at the bottom of the handle. This design has obvious limitations in actual use: when users replace the power supply, they need to flip or invert the entire device. Especially when the device is in operation or cleaning a small space, the operation posture with the bottom opening is extremely inconvenient. This not only increases the difficulty of assembly, but may also cause the device to slip due to unstable hand force.

[0004] Meanwhile, power compartments with bottom openings generally lack effective positioning and guiding structures. During power insertion, they are prone to misalignment due to obstructed vision or misalignment. This not only requires repeated adjustments to complete the assembly but may also cause misalignment and wear between the power interface and the contacts inside the compartment, affecting the stability of power transmission. Long-term use may even shorten the lifespan of the power supply and equipment. Therefore, in view of the shortcomings of existing power compartments at the bottom of the handle in terms of ease of assembly and accuracy of connection, there is an urgent need for a structural design that can optimize the opening position and improve assembly stability. Summary of the Invention

[0005] The main objective of this invention is to provide a handle device with an easy-to-assemble power supply and its portable dust removal equipment, aiming to solve the problems of insufficient ease of power supply assembly, connection stability and positioning accuracy in the handle.

[0006] To achieve the above objectives, the present invention provides a handle device with an easily assembled power supply, the handle device comprising: The main body housing has a power supply compartment inside, which accommodates the power supply, and an opening on one side of the main body housing that communicates with the power supply compartment and the outside of the main body housing. A cover plate is used to cover the opening. A first fastening component is provided on the side of the cover plate facing the opening. A second fastening component that cooperates with the first fastening component is provided on the inner wall surface of the power compartment near the opening. The cover plate and the main body shell are connected detachably by the fastening of the first fastening component and the second fastening component. A first positioning and fixing insertion component is provided on the end face of the opening facing the cover plate, and a second positioning and fixing insertion component is provided on the side of the cover plate facing the opening. The first positioning and fixing insertion component and the second positioning and fixing insertion component form a guiding cooperation during the fastening process of the first fastening component and the second fastening component, and enhance the connection stability of the first fastening component and the second fastening component after fastening.

[0007] A portable dust removal device includes a dust removal component, a blower component, and the aforementioned handle device. The blower component is electrically connected to the dust removal component, and the handle device is located at the bottom of the blower component and is electrically connected to both the blower component and the dust removal component. The dust removal component removes dust by blowing air through the blower component.

[0008] The beneficial effects of this invention are as follows: By setting the power compartment opening on the side of the main body shell, compared with the traditional bottom opening design, the power supply can be installed and removed without flipping the device, which significantly improves the ease of operation. Secondly, the cover plate and the main body shell are detachably connected through the first and second fastening components, avoiding the cumbersome operation of screw fixing. At the same time, in conjunction with the first and second positioning and fixing plug-in components, a precise guide is formed during the fastening process to ensure that the fastening is in place. After fastening, it can also enhance the overall connection stability, effectively prevent the cover plate from loosening and falling off, reduce component wear caused by assembly misalignment, and extend service life.

[0016] This invention provides a handle device with an easily assembled power supply; please refer to [reference needed]. Figures 1-7 The handle device 100 includes a main body housing 1 and a cover plate 2. The main body housing 1 has a power compartment 11 for accommodating a power source 400, and one side of the main body housing 1 has an opening communicating with the power compartment 11 and the outside of the main body housing 1. The cover plate 2 is used to seal the opening. A first fastening component is provided on the side of the cover plate 2 facing the opening. A second fastening component, which cooperates with the first fastening component, is provided on the inner wall of the power compartment 11 near the opening. The cover plate 2 and the main body housing 1 are detachably connected by the fastening of the first and second fastening components. A first positioning and fixing insertion component is provided on the end face of the opening facing the cover plate 2, and a second positioning and fixing insertion component is correspondingly provided on the side of the cover plate 2 facing the opening. The first and second positioning and fixing plug-in components form a guiding fit during the fastening process of the first and second fastening components, and enhance the connection stability of the first and second fastening components after fastening. The above design places the opening on the side of the handle, which can complete the installation and removal of the power supply 400 without flipping the device, significantly improving the ease of operation. Secondly, in conjunction with the first and second positioning and fixing plug-in components, the first and second fastening components can form a precise guide during the fastening process, ensuring that the fastening is in place. After fastening, it can also enhance the overall connection stability, effectively prevent the cover plate 2 from loosening and falling off, reduce component wear caused by assembly misalignment, and extend service life.

[0017] In this embodiment, please refer to Figures 1-5 The first fastening assembly includes several fastening blocks 21, which are evenly distributed on the left and right sides of the cover plate 2. The second fastening assembly includes fastening grooves 12 that match the number of fastening blocks 21. The fastening blocks 21 fasten with the corresponding fastening grooves 12. The main function of the above design is to enhance the stability and balance of the fastening between the cover plate 2 and the main body shell 1. By evenly distributing several fastening blocks 21 on the left and right sides of the cover plate 2 and correspondingly setting matching fastening grooves 12 on the inner wall of the power supply compartment 11, the fastening force is evenly distributed along both sides of the cover plate 2, avoiding single-point or localized fastening. The excessive force on the part can cause unstable fastening. Secondly, the symmetrical fastening layout on the left and right sides, combined with the precise fit of the fastening block 21 and the fastening groove 12, can not only ensure that the cover plate 2 and the main body shell 1 are quickly aligned and fastened, but also form a stable connection with balanced force at multiple points after fastening. This effectively prevents the cover plate 2 from loosening or falling off due to force on one side, and further improves the reliability of the connection of the cover plate 2 at the side opening. Finally, the above structure works together with the first and second positioning and fixing plug-in components to jointly ensure the structural stability of the handle device 100 and the safety of the power supply 400 installation. Furthermore, the side of the fastening block 21 facing the opening is provided with a first guide slope 211. This design is mainly to ensure that the fastening block 21 can be smoothly fastened with the fastening groove 12, and also to reduce the friction between the fastening block 21 and the inner wall of the power supply compartment 11, thereby extending the life of the fastening block 21. It should be noted that in other embodiments, the structural forms of the first fastening component and the second fastening component can be flexibly replaced. For example, the first fastening component can be set as a fastening groove 12, and the second fastening component can be set as an adapted fastening block 21. The cover plate 2 and the main body shell 1 are fastened and fixed by the reverse engagement of the groove and the block.

[0018] In addition, other fastening structures can be used, such as the first fastening component being an elastic hook and the second fastening component being a snap hole adapted to the hook, using the elastic deformation of the hook to achieve fastening and separation, or the first fastening component being a protruding post and the second fastening component being an elastic annular snap fastener, using the radial clamping force formed after the protruding post is inserted into the snap fastener to complete the fixation; although these alternative forms have different structural details, they can all achieve the detachable connection function between the cover plate 2 and the main body shell 1, and with the positioning and fixing plug-in components, the guiding of the fastening process and the stability of the connection after fastening can also be guaranteed. It is only necessary to select the appropriate structural form according to the actual assembly requirements, material characteristics and stress conditions.

[0019] In this embodiment, please refer to Figure 2 and Figure 3 The first positioning and fixing insertion assembly includes several positioning and fixing blocks 13, which are evenly distributed on the left and right end faces of the opening. The second positioning and fixing insertion assembly includes positioning and fixing slots 22 that match the number of positioning and fixing blocks 13. The positioning and fixing blocks 13 are inserted into the corresponding positioning and fixing slots 22. Specifically, during the assembly process, the positioning and fixing blocks 13 evenly distributed on the left and right end faces of the opening and the corresponding positioning and fixing slots 22 on the side of the cover plate 2 form a precise insertion fit, which can provide a clear guiding path for the cover plate 2 to be fastened. That is, before the first fastening assembly and the second fastening assembly are connected, the positioning and fixing blocks 13 are first inserted into the positioning and fixing slots 22 to quickly calibrate the relative position of the cover plate 2 and the main body shell 1, so as to avoid the cover plate 2 from shifting or misaligning to the left or right, and to ensure that the first fastening assembly and the second fastening assembly are accurately fastened. The above design greatly reduces the assembly difficulty and improves the assembly efficiency. Furthermore, the side of the positioning and fixing block 13 facing the cover plate 2 is provided with a second guide slope 131. The second guide slope 131 can form a natural guide slope through the tilt angle. Even if there is a slight positional deviation of the cover plate 2, the slope can automatically calibrate the cover plate 2 through the sliding action when in contact, guiding the positioning and fixing block 13 to slide more smoothly into the positioning and fixing groove 22. At the same time, it also reduces the wear of the first and second positioning and fixing plug components that may be caused by forced fastening, further improving the convenience of assembly and structural durability of the handle device 100 power supply 400.

[0020] In this embodiment, along the vertical direction of the main body shell 1, the positioning and fixing block 13 is located between the two fastening grooves 12, and along the vertical direction of the cover plate 2, the positioning and fixing groove 22 is located between the two fastening blocks 21. The above layout design allows the positioning components to form effective support between the fastening components, avoiding deformation of the fastening blocks 21 or fastening grooves 12 due to local force concentration. At the same time, the staggered distribution ensures that the connection force between the cover plate 2 and the main body shell 1 is evenly transmitted along the vertical direction, preventing unilateral loosening due to uneven force. This further strengthens the synergistic effect of the first and second fastening components and the first and second positioning and fixing insertion components, ensuring that the cover plate 2 is under overall force balance after fastening, and improving the stability and durability of the handle device 100 structure. In other embodiments, the structural forms of the first positioning and fixing plug-in component and the second positioning and fixing plug-in component can be flexibly interchanged. For example, the first positioning and fixing plug-in component can be set as a positioning and fixing groove 22, and a corresponding number of positioning and fixing blocks 13 can be set in the second positioning and fixing plug-in component. The positioning and guiding function is achieved through the reverse plugging and cooperation of the groove and the blocks.

[0021] In this replacement configuration, the positioning and fixing grooves 22 can be evenly distributed on the left and right end faces of the opening, while the positioning and fixing blocks 13 are correspondingly set on the side of the cover plate 2 facing the opening. When the two are inserted, they can also provide precise guidance for the cover plate 2 to fasten, ensuring that the fastening components can be smoothly connected. After the fastening is completed, the tight cooperation between the positioning and fixing blocks 13 and the positioning and fixing grooves 22 can still restrict the displacement of the cover plate 2 laterally, forming a cooperative limit with the fastening components and enhancing the overall connection stability.

[0022] In this embodiment, please refer to Figures 2-4 A positioning block 14 is provided on the bottom wall of the power compartment 11 near the opening, and a positioning plate 23 is provided on the cover plate 2 facing the opening near the bottom. The positioning plate 23 is provided with a positioning groove 231 that engages with the positioning block 14. After the positioning block 14 engages with the positioning groove 231, the positioning plate 23 is located below the support plate 15, which not only achieves precise bottom positioning but also forms a collaborative support structure. Specifically, the engagement of the positioning block 14 with the positioning groove 231 supplements the bottom positioning dimension and, together with the first positioning and fixing plug-in component and the second positioning and fixing plug-in component, achieves precise circumferential guidance of the cover plate 2, ensuring smooth docking of the first and second fastening components. On the other hand, the positioning plate 23 forms a support below the support plate 15, dispersing the pressure of the power supply 400 on the support plate 15 and preventing deformation of the support plate 15, thereby enhancing the assembly accuracy, structural stability, and service life of the handle device 100 as a whole.

[0023] Following the above, the side of the positioning block 14 facing the cover plate 2 is provided with a third guide slope 141, and the side of the positioning plate 23 facing the opening is provided with a fourth guide slope 232 that matches the third guide slope 141. This arrangement mainly uses the third guide slope 141 and the fourth guide slope 232 to enhance the guiding nature and assembly smoothness of the bottom fastening structure. Specifically, during the fastening process of the cover plate 2, when the positioning block 14 and the positioning plate 23 begin to contact, the two sets of matching slopes will form a natural sliding guide, even if the bottom of the cover plate 2... Even with slight positional deviations, the lateral force generated by the inclined contact can automatically calibrate the position of the cover plate 2, guiding the positioning block 14 to slide precisely into the positioning groove 231, avoiding jamming or misalignment during bottom fastening. At the same time, the inclined design reduces the force required during fastening, making the bottom fastening operation more effortless. Combined with the fastening function of the positioning block 14 and the positioning groove 231, and the supporting role of the positioning plate 23 on the bearing plate 15, it further improves the convenience and accuracy of bottom assembly of the handle device 100, ensuring smoother and more stable overall structure fastening.

[0024] In this embodiment, a limiting plate 16 and a supporting plate 15 extending along the insertion direction of the power supply 400 are provided on the two opposite inner side walls of the power supply compartment 11. The limiting plate 16 is located above the supporting plate 15, and the power supply 400 is placed between the limiting plate 16 and the supporting plate 15. The main function of this design is to accurately limit and stably support the installation of the power supply 400 in the power supply compartment 11. Specifically, the limiting plate 16 limits the power supply from above, and the supporting plate 15 supports it from below, thereby forming an upper and lower clamping structure. This allows the power supply 400 to be smoothly pushed along a preset path during insertion, avoiding left and right swaying or deviation, and ensuring that the power supply 400 accurately connects with the electrical contacts in the compartment. At the same time, this structure, together with the side opening and the fastening and positioning components, improves the overall assembly accuracy and safety of the handle device 100.

[0025] This invention also provides a portable dust removal device, please refer to [reference needed]. Figure 1 It includes a dust removal component 300, a blower component 200 and the aforementioned handle device 100. The blower component 200 is electrically connected to the dust removal component 300. The handle device 100 is located at the bottom of the blower component 200 and is electrically connected to both the blower component 200 and the dust removal component 300. The dust removal component 300 removes dust by blowing air from the blower component 200.
