Technical Field
[0001] This utility model relates to the field of cleaning brush technology, specifically a cleaning brush. Background Technology
[0002] Cleaning brushes are widely used in cleaning homes, cars, industrial equipment, and other scenarios. Their convenience, cleaning efficiency, and adaptability directly affect the user experience. With the diversification of cleaning needs, existing cleaning brush structures have significant shortcomings, as detailed below:
[0003] First, most existing cleaning brushes use a fixed connection between the brush head and the body, or a complex semi-fixed snap-fit structure. The former results in a single function for the brush head, making it unsuitable for different cleaning scenarios. Users need to purchase multiple cleaning brushes, and the entire brush needs to be replaced after the brush head wears out, increasing usage costs and wasting resources. The latter has the problem of unstable connection, which is prone to loosening, falling off, or slipping during high-speed cleaning, affecting efficiency and safety.
[0004] Secondly, existing cleaning brushes are powered in two ways: one is wired power, which is limited by the length of the power cord and cannot flexibly cope with scenarios far from the power source, and is easy to get tangled during operation; the other is powered by a built-in non-removable battery, which gets rid of the wired limitation, but the whole machine needs to be charged after the power is exhausted, which leads to cleaning interruption. When the battery degrades or is damaged, the whole machine needs to be scrapped, which is not only environmentally friendly but also increases costs.
[0005] Third, most cleaning brushes use a "motor directly drives the brush head" structure, which lacks optimized design: without a gearbox, the speed is fixed, making it difficult to adapt to different stain cleaning needs and increasing the intensity of operation; some products with transmission structures have a simple connection between the gear and the brush head, which is prone to slippage and results in insufficient power transmission; and the drive components are rigidly fixed in the body, which is prone to loosening under high-frequency vibration, aggravating noise, reducing efficiency and shortening life. Utility Model Content
[0006] In order to overcome the shortcomings of existing technical solutions, this utility model provides a cleaning brush that can effectively solve the technical problems of insufficient brush head replacement convenience, limited power supply, and unreasonable driving power of current cleaning brushes.
[0007] The technical solution adopted by this utility model to solve its technical problem is:
[0008] A cleaning brush includes a body, a brush head, and a lithium battery. The body houses a drive assembly and an electronic control board. The drive assembly comprises a gearbox and gears. The output end of the gearbox extends outward from the body and is coaxially connected to the gears. One end of the brush head has a groove that matches the gears, and the brush head is detachably connected to the gearbox and gears via the groove. The end of the groove facing the opening has a protrusion that locks with the gears. The electronic control board is electrically connected to the gearbox and drives the brush head to rotate by controlling the gearbox. A battery slot is located on one side of the body, and the lithium battery is detachably installed in the battery slot and connected to the electronic control board for power supply.
[0009] Furthermore, the gear component has a polygonal cross-section and includes a first connecting portion connected to the output end of the gearbox, and a second connecting portion that is snapped and fixed inside the groove.
[0010] Furthermore, the gearbox is a variable speed motor with adjustable output speed.
[0011] Furthermore, the housing is equipped with an arc-shaped component for fixing the gearbox, and the gearbox is fixed by adjusting the clamping force at both ends of the arc-shaped component.
[0012] Furthermore, the electronic control board is equipped with touch buttons for controlling the transmission.
[0013] Furthermore, a battery cover is installed at one end of the body where the battery slot is located, which is a sealed cover for the lithium battery. The battery cover is detachably connected to the body via buckles on both sides.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] (1) The drive assembly consists of a gearbox and gear components, and is precisely matched with the brush head components. This reduces power loss during power transmission. Combined with the power adjustment function of the gearbox, it can effectively increase the working power of the cleaning brush, enhance the cleaning force when the brush head components rotate, and optimize cleaning efficiency and effect.
[0016] (2) The brush head is detachably connected to the gear part through the groove, which makes it convenient to quickly replace the functional brush head to adapt to different cleaning scenarios, and can also be replaced separately after the brush head is worn, reducing the cost of use and improving the adaptability and practicality of the cleaning brush.
[0017] (3) The lithium battery can be detached and installed in the battery slot of the machine body. It can be easily removed for charging without disassembling the whole machine. It can also directly replace the spare lithium battery to avoid interruption of use due to waiting for charging, ensure continuous cleaning operation, and facilitate the later maintenance or replacement of the lithium battery, thus extending the overall service life of the cleaning brush.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] like Figures 1-2As shown, this utility model provides a cleaning brush, mainly used for cleaning operations in various scenarios, such as cleaning tableware and furniture surfaces in the home, as well as cleaning car interiors and equipment shells. The cleaning brush structure, through a modular design, enables convenient disassembly and assembly of each component and functional adjustment, improving the flexibility and practicality of cleaning operations. Furthermore, different types of brush heads can be replaced to meet different cleaning functions.
[0034] like Figures 3-6 As shown, the whole consists of three core components: body 1, brush head 2, and lithium battery 3. The body 1 integrates drive component 4 and electronic control board 5. Drive component 4 provides rotational power to brush head 2, electronic control board 5 controls drive component 4, and lithium battery 3 provides the power required for the entire cleaning brush structure to work.
[0035] The body 1, serving as the main support for the entire cleaning brush structure, adopts an ergonomic design for easy gripping by the operator. A battery slot 101 is located on one side of the body 1, its size matching that of the lithium battery 3, providing a stable installation space for the battery. Simultaneously, the body 1 also contains an arc-shaped component 6 for securing the gearbox 41. Made of a material with a certain degree of elasticity, the arc-shaped component 6 allows for adjustable clamping force at both ends to firmly fix the gearbox 41, preventing positional displacement due to vibration during operation and ensuring the stability of the drive assembly 4.
[0036] In addition, a battery cover 7 for sealing and covering the lithium battery 3 is installed at one end of the body 1 where the battery slot 101 is located. The battery cover 7 is detachably connected to the body 1 by buckles 701 on both sides. When it is necessary to replace or recharge the lithium battery 3, simply pry the buckles 701 outward to remove the battery cover 7 from the body 1. When installing the battery cover 7, align the battery cover 7 with the opening end of the battery slot 101, press the two sides of the battery cover 7 so that the buckles 701 are engaged in the corresponding slots on the body 1, and the installation of the battery cover 7 is completed. This effectively protects the lithium battery 3 and prevents sewage and impurities from entering the battery slot 101 and damaging the lithium battery 3 during the cleaning process.
[0037] The drive assembly 4 consists of a gearbox 41 and a gear assembly 42, which work together to provide rotational power to the brush head 2. The output end of the gearbox 41 extends outward from the body 1 and is coaxially connected to the gear assembly 42, ensuring that the power output from the gearbox 41 can be stably and efficiently transmitted to the gear assembly 42. The gearbox 41 is a variable-speed motor with adjustable output speed. The operator can adjust the output speed of the gearbox 41 via the electronic control board 5 according to different cleaning needs, thereby changing the rotational speed of the brush head 2. For example, when cleaning stubborn stains, the output speed of the gearbox 41 can be increased to enhance the cleaning power of the brush head 2; when cleaning the surface of fragile objects, the output speed of the gearbox 41 can be reduced to prevent the brush head 2 from scratching the surface of the object.
[0038] The gear component 42 has a polygonal cross-section. This design effectively improves the transmission stability between the gear component 42 and the brush head component 2, preventing relative slippage during transmission. Specifically, the gear component 42 includes a first connecting portion 421 and a second connecting portion 422. The first connecting portion 421 is fixedly connected to the output end of the gearbox 41, ensuring a reliable connection between the gear component 42 and the gearbox 41. The second connecting portion 422 is used to snap-fit and fix the brush head component 2. Its dimensions match the groove 201 on the brush head component 2, ensuring a tight fit between the two.
[0039] The brush head 2 is the component that directly contacts the object to be cleaned. One end of the brush head 2 has a groove 201 that matches the gear 42. The shape of the groove 201 matches the polygonal cross-sectional structure of the gear 42, allowing the second connecting part 422 of the gear 42 to be smoothly inserted into the groove 201. At the same time, the end of the groove 201 facing the opening has a barb 202. When the second connecting part 422 of the gear 42 is inserted into the groove 201, the barb 202 will lock with the gear 42, further enhancing the connection between the brush head 2 and the gear 42 and preventing the brush head 2 from disengaging from the gear 42 during rotation.
[0040] Based on the above structure, the brush head 2 and the gearbox 41 are detachably connected via the groove 201 and the gear 42. When it is necessary to replace different types of brush heads 2 (such as hard-bristled brush heads, soft-bristled brush heads, sponge brush heads, etc. for different cleaning scenarios), simply hold the brush head 2 and pull it outward to disengage the barb 202 from the gear 42, thus removing the brush head 2 from the gear 42. When installing a new brush head 2, align the groove 201 of the brush head 2 with the second connecting part 422 of the gear 42, and push the brush head 2 firmly until the second connecting part 422 of the gear 42 is fully inserted into the groove 201 until the barb 202 locks with the gear 42, completing the installation of the brush head 2. The operation is convenient and efficient. In use, users can choose to install brush heads 2 with different functions and structures to meet different cleaning environments and requirements.
[0041] The electronic control board 5 is installed inside the body 1 and is electrically connected to the gearbox 41. Its core function is to drive the brush head 2 to rotate by controlling the gearbox 41. The electronic control board 5 is equipped with a touch button 501, allowing the operator to perform various operations on the cleaning brush structure, such as starting the cleaning brush, stopping the cleaning brush, and adjusting the output speed of the gearbox 41. The touch button 501 makes operation more intuitive and convenient, improving the user experience.
[0042] The lithium battery 3 is detachably installed in the battery slot 101 of the main body 1 and connected to the electronic control board 5, providing power for the operation of the entire cleaning brush structure. The lithium battery 3 features a detachable design; when the lithium battery 3 is depleted, the operator can remove the battery cover 7 and take the lithium battery 3 out of the battery slot 101 for charging, or directly replace it with a fully charged lithium battery 3, without waiting for it to fully charge, effectively ensuring the continuous working capability of the cleaning brush structure. At the same time, the use of the lithium battery 3 frees the cleaning brush structure from the constraints of traditional wired power supply, allowing operators to use the cleaning brush in any scenario, thus improving the flexibility of the cleaning brush structure.
[0043] When using this cleaning brush structure for cleaning operations, first select the appropriate brush head 2 according to the type of object to be cleaned and the cleaning requirements, and install it on the output end of the gearbox 41 through the cooperation of the groove 201 and the gear 42, ensuring that the barb 202 is locked with the gear 42; then, install the fully charged lithium battery 3 into the battery slot 101 of the body 1, and cover the battery cover 7, so that the buckle 701 is locked and fixed to the body 1.
[0044] After completing the above preparations, the operator holds the machine body 1, aligns the brush head 2 with the surface of the object to be cleaned, and starts the cleaning brush structure by touching the button 501. After receiving the start signal, the electronic control board 5 controls the gearbox 41 to start working. The gearbox 41 outputs power at the corresponding speed according to the control command of the electronic control board 5. This power is transmitted to the brush head 2 through the gear 42, driving the brush head 2 to rotate at the set speed. During the rotation, the brush head 2 contacts the surface of the object to be cleaned, thus cleaning the stains on the surface of the object.
[0045] During the cleaning process, the operator can adjust the output speed of the gearbox 41 via touch button 501 to change the rotation speed of the brush head 2, achieving the best cleaning effect. After cleaning, the cleaning brush structure is closed via touch button 501, the gearbox 41 stops working, and the brush head 2 stops rotating. If the lithium battery 3 is depleted, the battery cover 7 can be removed to replace the lithium battery 3 or to recharge the removed lithium battery 3 for future use.
[0046] Compared to traditional technologies, the cleaning brush provided by this technical solution features a drive component consisting of a gearbox and gears that precisely match the brush head. This reduces power loss during transmission, and the gearbox's power adjustment effectively increases the brush's working power, enhancing the cleaning force during brush head rotation and optimizing cleaning efficiency and effectiveness. The brush head is detachably connected to the gears via grooves, facilitating quick and easy replacement of functional brush heads for different cleaning scenarios. It also allows for individual replacement of worn brush heads, reducing operating costs and improving the brush's adaptability and practicality. The lithium battery is removably installed in the battery compartment of the main unit, allowing for easy removal and charging without disassembling the entire device. It also allows for direct replacement of spare lithium batteries, preventing interruptions due to charging delays and ensuring continuous cleaning. Furthermore, it facilitates future maintenance or replacement of the lithium battery, extending the overall lifespan of the cleaning brush.
[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
