Description

Technical Field

[0001] This utility model relates to the field of mite removal device technology, and more specifically, it relates to a mite removal device roller brush structure. Background Technology

[0002] In modern home environments, dust mites are a common allergen, and their control has become an important part of maintaining a healthy home environment. Especially in homes with a lot of fabrics, such as bedrooms, sofas, and carpets, dust mites can easily multiply and cause health problems such as allergic rhinitis and asthma. As a household appliance specifically designed to remove dust mites, the core working component of a dust mite remover, the roller brush, needs to directly contact the surface of the fabric for deep cleaning.

[0003] However, most existing mite remover roller brushes use a fixed installation structure, making disassembly and assembly cumbersome and requiring tools or multiple steps. This design causes many inconveniences in daily use, especially when the roller brush is entangled in hair or needs cleaning. The complicated disassembly and assembly process significantly reduces the user's willingness to clean and the user experience, affecting the sustainability of the mite removal effect and the lifespan of the device.

[0004] In practical applications of mite removers, the roller brush, as the part that directly contacts dirt, requires regular cleaning and maintenance to maintain good mite removal performance. Especially for different usage scenarios such as mattresses, sofas, and carpets, different types of roller brushes may be needed to achieve the best cleaning results.

[0005] However, existing roller brush fixing mechanisms mostly use screw fastening, snap-fit ​​embedding and other methods. These structures often require the use of special tools to disassemble and are prone to wear and deformation due to long-term use, resulting in problems such as insecure fixing or difficulty in disassembly. Utility Model Content

[0006] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a mite removal device roller brush structure to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a mite remover roller brush structure, comprising a mite remover body and a roller brush body. The mite remover body has an installation groove, and a transmission wheel is connected in the installation groove. Both ends of the roller brush body have insertion holes. The bottom end of the roller brush body has an installation shaft. An insertion block is rotatably connected to the outside of the installation shaft. A slot is provided in the installation groove, and the insertion block is inserted into the slot. A fixing plate is abutted against the bottom end of the insertion block. A locking rod is fixed in the installation groove, and the fixing plate is inserted into the insertion rod. A fixing sleeve is inserted into the top end of the locking rod. A control sleeve is rotatably installed on the top end of the fixing sleeve. A locking block is fixed on the inner wall of the control sleeve. Multiple sets of locking blocks are provided, and each set has a locking hole on its outer wall. A locking plate is fixed on the outer wall of the locking rod. Multiple sets of locking plates are provided.

[0008] The present invention is further configured such that insert rods are fixedly provided on both the transmission wheel and the mounting shaft, and multiple sets of insert rods are respectively inserted into the insertion holes. This design achieves a bidirectional and stable connection, ensuring that the roller brush body will not loosen during operation. It also makes the power transmission more direct and efficient, reduces energy loss, and improves the mite removal efficiency and equipment service life.

[0009] The present invention is further configured such that all of the multiple sets of insert rods and holes are polygonal. The polygonal structure prevents the insert rods from slipping or rotating in the holes, ensuring that the rotational force of the transmission wheel can be accurately transmitted to the brush body. At the same time, the polygonal design also enhances the torque resistance of the connection, so that the brush can still maintain stable operation when running at high speed or encountering resistance, and there will be no transmission failure.

[0010] The present invention is further configured such that a guide block is fixedly provided on the inner wall of the fixing sleeve, and a guide groove is provided on the outer wall of the snap-fit ​​rod. Multiple sets of the guide block and the guide groove are provided. This guiding structure ensures the precise alignment of the fixing sleeve and the snap-fit ​​rod during the connection process, preventing misalignment or skew during installation. At the same time, the multiple sets of guide blocks and guide grooves enhance the stability and load-bearing capacity of the connection, making the entire fixing mechanism more robust and reliable, and improving the safety of use.

[0011] The present invention is further provided that the outer sides of the multiple sets of card plates and card holes are provided with rounded corners. The rounded corner design makes the card plates and card holes smoother during the insertion process, reduces frictional resistance and the risk of jamming, and also reduces material stress concentration, preventing wear or breakage after long-term use, improving the service life of the components and the user experience, and enabling users to easily complete the installation and disassembly of the roller brush.

[0012] The present invention is further configured such that a movable hole is provided inside the snap-fit ​​rod, and a push rod is slidably provided inside the movable hole. A compression spring is provided between the bottom end of the push rod and the movable hole. This elastic ejection mechanism can automatically push the fixing sleeve away from the snap-fit ​​rod after the snap-fit ​​state is released, without the need for manual pulling by the user, which greatly simplifies the disassembly operation. At the same time, the design of the compression spring also provides appropriate buffering for the entire connection, reducing the impact and wear caused by hard contact and extending the service life of the components.

[0013] The present invention is further configured such that a positioning sleeve is fixedly provided on the bottom surface of the control sleeve, and a sliding hole is provided on the inner side of the positioning sleeve. Multiple sets of sliding holes are provided, and each set of sliding holes is connected to a push spring. A positioning block is fixedly provided at the bottom end of each set of push springs, and the multiple sets of positioning blocks slide in the sliding hole. This design forms an automatic positioning and locking mechanism, which enables the control sleeve to automatically lock after rotating into position, preventing accidental loosening due to vibration or collision during use. At the same time, the setting of multiple positioning structures provides a uniform locking force, enhancing the stability and reliability of the overall structure.

[0014] The present invention is further configured such that the outer wall of the fixing sleeve is provided with a positioning groove, and the positioning groove is provided in multiple sets and abuts against multiple sets of positioning blocks respectively. The bottom ends of the multiple sets of positioning blocks and the positioning grooves are all designed in an arc shape. The arc shape design makes the positioning blocks enter or leave the positioning groove more smoothly, reducing operating resistance and component wear. At the same time, it forms a progressive positioning mechanism, making the locking and unlocking process more stable and controllable. Users only need to slightly rotate the control sleeve to complete accurate positioning or unlock smoothly, which greatly improves the convenience of operation and user experience.

[0015] (III) Beneficial Effects Compared with the prior art, this utility model provides a mite removal device roller brush structure, which has the following beneficial effects: 1. The precise fit between the mounting slot, transmission wheel, and roller brush body enables convenient installation of the roller brush. In particular, the design of the polygonal plug and socket ensures the stability and efficiency of the transmission, avoiding the loosening or slippage of the roller brush in traditional mite removers during operation. At the same time, the cooperation between the plug and the slot further enhances the stability of the roller brush, enabling the mite remover to maintain stable operation during operation, greatly improving the mite removal efficiency and user experience, and solving the problem of the inconvenience of quick installation and fixation of the roller brush in existing technologies.

[0016] 2. The multiple sets of locking blocks inside the control sleeve and the locking plates on the locking rod form a solid locking structure. The rounded corner design of the locking plates and locking holes makes the locking process smoother. At the same time, the setting of guide blocks and guide grooves ensures precise alignment and connection between components.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0023] Please see Figures 1-5 A mite remover roller brush structure includes a mite remover body 1 and a roller brush body 2. The mite remover body 1 has an installation groove 3, and a transmission wheel 4 is connected in the installation groove 3. Both ends of the roller brush body 2 have insertion holes 5. The bottom end of the roller brush body 2 has an installation shaft 6. An insertion block 7 is rotatably connected to the outside of the installation shaft 6. The installation groove 3 has a slot 8, and the insertion block 7 is inserted into the slot 8. The bottom end of the insertion block 7 abuts against a fixing plate 9. A snap-fit ​​rod 10 is fixed in the installation groove 3. The fixing plate 9 is inserted into the snap-fit ​​rod. A fixing sleeve 11 is inserted into the top end of the snap-fit ​​rod 10. A control sleeve 12 is rotatably installed on the top end of the fixing sleeve 11. A snap-fit ​​block 13 is fixed on the inner wall of the control sleeve 12. Multiple snap-fit ​​blocks 13 are provided, and each has a snap-fit ​​hole 14 on its outer wall. Multiple snap-fit ​​plates 15 are fixed on the outer wall of the snap-fit ​​rod 10.

[0024] Both the drive wheel 4 and the mounting shaft 6 are fixedly equipped with insert rods 16. Multiple sets of insert rods 16 are inserted into the insertion holes 5 respectively. Through the bidirectional insertion connection, the roller brush body 2 is simultaneously and stably connected to both the drive wheel 4 and the mounting shaft 6. When the drive wheel 4 rotates, the power is directly transmitted to the roller brush body 2 through the insert rods 16, avoiding the loosening or falling off that may be caused by single-point connection. This forms a closed-loop fixed structure, ensuring the stability and transmission reliability of the roller brush body 2 during operation.

[0025] Multiple sets of insert rods 16 and insert holes 5 are all set as polygons. The geometric locking characteristics of polygons prevent the insert rods 16 from rotating relative to each other in the insert holes 5, ensuring that the rotational force of the transmission wheel 4 can be 100% transmitted to the roller brush body 2 without slippage. At the same time, the polygonal structure has a larger contact area and stronger anti-torque capability than a circle, and can withstand a larger workload and adapt to various resistance situations that may be encountered during the mite removal process.

[0026] The inner wall of the fixed sleeve 11 is fixed with a guide block 17, and the outer wall of the snap-fit ​​rod 10 is provided with a guide groove 18. Multiple sets of guide blocks 17 and guide grooves 18 are provided. During the connection between the fixed sleeve 11 and the snap-fit ​​rod 10, the guide block 17 slides along the guide groove 18 to ensure that the two parts can be accurately aligned and remain coaxial, preventing skewing or jamming during installation. The setting of multiple sets of guide structures provides uniform support and guidance, reduces single-point stress, and also restricts the fixed sleeve 11 to be connected to the snap-fit ​​rod 10 in a straight line along the preset track, thereby improving the accuracy and convenience of installation.

[0027] The outer sides of the multiple sets of locking plates 15 and locking holes 14 are all provided with rounded corners. The transition surface of the rounded corners allows the locking plates 15 to slide along the smooth surface when entering or leaving the locking holes 14, reducing the resistance and jamming that may be caused by the right-angled edges. At the same time, the rounded corner design also eliminates stress concentration points, avoiding possible breakage or deformation after long-term use, making the locking process smoother, reducing the difficulty of operation, extending the service life of components, and improving the reliability of the entire locking mechanism.

[0028] The snap-fit ​​rod 10 has a movable hole 19 inside, and a push rod 20 is slidably installed inside the movable hole 19. A compression spring 21 is connected between the bottom end of the push rod 20 and the movable hole 19. When the snap-fit ​​is released, the compression spring 21 releases the stored elastic potential energy and pushes the push rod 20 to slide outward along the movable hole 19. The push rod 20 then pushes the control sleeve 12 and the fixed sleeve 11 to automatically separate from the snap-fit ​​rod 10 without the user having to pull it manually, realizing a semi-automatic disassembly process. At the same time, the compression spring 21 can also provide appropriate cushioning during the installation process, reducing the impact and wear caused by hard contact.

[0029] A positioning sleeve 22 is fixedly provided on the bottom surface of the control sleeve 12. A sliding hole 23 is provided on the inner side of the positioning sleeve 22. Multiple sets of sliding holes 23 are provided, and each set of sliding holes 23 is connected to a push spring 24. A positioning block 25 is fixedly provided at the bottom end of each set of push springs 24. The positioning blocks 25 slide in the sliding holes 23. The push springs 24 continuously apply an outward elastic force to the positioning blocks 25, so that the positioning blocks 25 always try to extend out of the sliding holes 23. When the control sleeve 12 rotates to the predetermined position, the positioning blocks 25 automatically spring into the positioning groove 26 under the action of the push springs 24 to lock, preventing the control sleeve 12 from rotating on its own due to vibration or accidental collision. This forms an automatic locking mechanism, so that the user can complete the precise positioning and locking of the control sleeve 12 without additional operation.

[0030] The outer wall of the fixed sleeve 11 is provided with a positioning groove 26. The positioning groove 26 is provided in multiple sets and abuts against multiple sets of positioning blocks 25 respectively. The bottom ends of the multiple sets of positioning blocks 25 and the positioning groove 26 are all designed to be arc-shaped. When unlocking is required, the control sleeve 12 starts to rotate. The bottom end of the arc-shaped positioning block 25 slides along the arc wall of the positioning groove 26, generating a progressive thrust, gradually compressing the push spring 24, so that the positioning block 25 smoothly retracts into the sliding hole 23, avoiding the impact that may be caused by sudden disengagement. At the same time, the arc design also reduces sliding friction, making the whole unlocking process easier and smoother. The user only needs to apply a small torque to complete the rotation unlocking operation of the control sleeve 12.

[0031] In this embodiment, when the roller brush body 2 needs to be installed, the insertion hole 5 at the top of the roller brush body 2 is inserted into the insertion hole 5 on the transmission wheel 4, and the insertion rod 16 installed on the mounting shaft 6 is inserted into the insertion hole 5. Then, the insertion block 7 is inserted into the slot 8, and then the fixing plate 9 is inserted into the snap-fit ​​rod 10 so that the fixing plate 9 abuts against the bottom surface of the insertion block 7. Then, the fixing sleeve 11 is inserted into the snap-fit ​​rod 10, and multiple sets of guide blocks 17 are inserted into the guide groove 18. The push rod 20 is pushed along the movable hole 19 by the inner side of the control sleeve 12 and the compression spring 21 is compressed. After the snap-fit ​​rod 10 is fully inserted into the fixed sleeve 11, the control sleeve 12 is rotated to drive the multiple sets of snap-fit ​​blocks 13 to rotate, so that the multiple sets of snap-fit ​​plates 15 are inserted into the snap-fit ​​holes 14. Then, the positioning block 25 is pushed into the positioning groove 26 by the multiple sets of push springs 24 to complete the positioning of the control sleeve 12, and the fixed plate 9 is pressed and fixed, thus completing the installation of the roller brush body 2.

[0032] More specifically, when the roller brush body 2 needs to be disassembled, the rotating control sleeve 12 drives multiple sets of locking blocks 13 to rotate, causing multiple sets of locking plates 15 to disengage from the locking holes 14, releasing the locking of the locking rod 10. While the control sleeve 12 rotates, it drives the positioning sleeve 22 to rotate, pushing the positioning block 25 to slide along the sliding hole 23 through multiple sets of positioning grooves 26 and squeezing multiple sets of push springs 24. The continuous rotation of the positioning sleeve 22 causes the multiple sets of positioning blocks 25 to move within the multiple sets of positioning grooves 26. The compression spring 21 resets and pushes the push rod 20 to slide along the movable hole 19. The push rod 20 pushes the control sleeve 12 to drive the fixing sleeve 11 to disengage from the locking rod 10, releasing the abutment of the fixing plate 9. Then the fixing plate 9 can be separated from the locking rod 10 to release the abutment of the insert block 7, and then the roller brush body 2 can be disassembled.

[0033] In summary, during the use or operation of the overall equipment: when it is necessary to install the roller brush body 2, insert the insertion hole 5 at the top of the roller brush body 2 into the insertion hole 5 on the transmission wheel 4, and insert the insertion rod 16 installed on the mounting shaft 6 into the insertion hole 5. Then, insert the insertion block 7 into the slot 8, and then insert the fixing plate 9 into the snap-fit ​​rod 10 so that the fixing plate 9 abuts against the bottom surface of the insertion block 7. Then, insert the fixing sleeve 11 into the snap-fit ​​rod 10, and then insert the multiple sets of guide blocks 17 into the guide groove 18. The insertion is performed by pushing the push rod 20 along the movable hole 19 through the inside of the control sleeve 12 and compressing the compression spring 21. After the snap-fit ​​rod 10 is fully inserted into the fixed sleeve 11, the control sleeve 12 is rotated to drive the multiple sets of snap-fit ​​blocks 13 to rotate, so that the multiple sets of snap-fit ​​plates 15 are inserted into the snap-fit ​​holes 14. Then, the multiple sets of push springs 24 push the positioning block 25 to abut against the positioning groove 26, thereby completing the positioning of the control sleeve 12 and tightening and fixing the fixed plate 9, thus completing the installation of the roller brush body 2.

[0034] When the roller brush body 2 needs to be disassembled, the rotating control sleeve 12 drives multiple sets of locking blocks 13 to rotate, causing multiple sets of locking plates 15 to disengage from the locking holes 14, releasing the locking of the locking rod 10. At the same time, the rotation of the control sleeve 12 drives the positioning sleeve 22 to rotate, pushing the positioning block 25 to slide along the sliding hole 23 through multiple sets of positioning grooves 26 and squeezing multiple sets of push springs 24. The continuous rotation of the positioning sleeve 22 causes the multiple sets of positioning blocks 25 to move within the multiple sets of positioning grooves 26. The compression spring 21 resets and pushes the push rod 20 to slide along the movable hole 19. The push rod 20 pushes the control sleeve 12 to drive the fixing sleeve 11 to disengage from the locking rod 10, releasing the abutment of the fixing plate 9. Then the fixing plate 9 can be separated from the locking rod 10 to release the abutment of the insert block 7, and then the roller brush body 2 can be disassembled.
