Description

Technical Field

[0001] This utility model relates to the technical field of bath brushing devices, and more specifically, to a bath brushing device that is easy to operate and use. Background Technology

[0002] Currently, shower cleaning largely relies on traditional hand brushes, sponges, or cloths. These methods depend entirely on manual rubbing to achieve a cleaning effect, requiring users to apply continuous pressure to generate sufficient friction between the bristles and the skin. For hard-to-reach areas like the back and shoulders, it's difficult to reach or maintain a sufficient angle, resulting in incomplete cleaning and often requiring repeated wiping, which is time-consuming and laborious.

[0003] As a result, some electric bath brushes have appeared on the market. Although they use motors to drive the brush head to rotate or vibrate in order to reduce the burden on manual labor, most of them have many problems such as large size, heavy weight, inconvenient operation, and easy malfunction. At the same time, the simple continuous rotation or up-and-down vibration mode is not adaptable to the cleaning angle, and cannot take into account the required cleaning angle for different parts of the body with a single brush.

[0004] In particular, when users with limited mobility, such as the elderly, are taking a bath, caregivers often find it difficult to clean them thoroughly, or they may have to scrub them quite vigorously. This causes pain for the elderly and is especially time-consuming and laborious. Furthermore, when users bathe themselves, it is difficult to thoroughly clean areas such as the back and other parts of the body where they cannot exert force. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a bath brush that is easy to operate and use, so as to solve the above problems.

[0006] The present invention adopts the following solution:

[0007] This application provides a shower brush that is easy to operate and use, including a main body, a handle, and a bristle component that is oscillatingly disposed on the main body; the main body is provided with a drive component and a transmission component, the transmission component being used to transmit the power output by the drive component to the bristle component through eccentric rotation, thereby driving the bristle component to perform reciprocating forward and reverse rotational oscillation along the axial direction at an angle.

[0008] As a further improvement, under the transmission of the transmission assembly, the bristles rotate and oscillate at an acute angle in the positive direction along the axial direction, and the bristles rotate and oscillate at an acute angle in the opposite direction along the axial direction.

[0009] As a further improvement, the acute angle is in the range of 30° to 55°.

[0010] As a further improvement, a flexible silicone sleeve is provided between the brush bristles and the rotating part.

[0011] As a further improvement, the handle is attached to the lower end of the main body via a shock-absorbing soft rubber.

[0012] As a further improvement, the drive assembly includes a brushless motor; the transmission assembly includes a rotor component mated to the brushless motor, a rocker arm component eccentrically connected to the rotor component, and a rocker shaft rotatably connected to the rocker arm component; wherein, the rocker shaft is drively connected to the bristle component and is used to drive the bristle component to rotate freely in forward or reverse direction.

[0013] As a further improvement, the rotor is provided with an eccentric shaft, and the rocker arm is rotatably connected to the eccentric shaft.

[0014] As a further improvement, the rocking shaft is eccentrically positioned on the end of the rocking rod that is away from the eccentric shaft.

[0015] As a further improvement, the rear end of the main body is provided with an end cap and a motor bracket, and the brushless motor is mounted on the motor bracket.

[0016] As a further improvement, a circuit board is also included on the motor bracket; the handle is provided with a battery and a button, and the circuit board is electrically connected to the brushless motor, the battery and the button respectively.

[0017] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0018] 1. The easy-to-use scrubber of this application integrates a drive component and a transmission component within the main body. The transmission component converts the power output by the motor into the reciprocating forward and reverse rotation of the bristles along the axial direction by means of eccentric rotation. This eliminates the need for the user to manually push the brush repeatedly and significantly, thus achieving continuous and stable cleaning action, greatly reducing labor intensity and improving cleaning efficiency.

[0019] 2. The bristles are oscillatingly mounted on the main body. Through eccentric rotation, the bristles automatically shift upwards and eccentrically engage during cleaning. This allows them to reach deep into irregular areas such as skin and crevices while maintaining a uniform fit, making it suitable for deep cleaning needs of various parts of the body. Furthermore, the drive and transmission components are integrated into the compact main body, along with an ergonomic handle. Users can hold the brush firmly with one hand and easily start and stop it, making it simpler and more convenient to use. The internal transmission layout of the main body is reasonable, the connections between various structural components are reliable, and assembly and disassembly are convenient.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0025] Example

[0026] Combination Figures 1 to 3 This embodiment provides a user-friendly bath brush, including a main body 1, a handle 2, and a bristle 3 that is oscillatingly mounted on the main body 1. The main body 1 is provided with a drive assembly and a transmission assembly. The transmission assembly is used to transmit the power output by the drive assembly to the bristle 3 through eccentric rotation, thereby driving the bristle 3 to perform reciprocating forward and reverse rotational oscillation along the axial direction at an angle.

[0027] The aforementioned scrubber integrates a drive component and a transmission component within the main body 1. The transmission component converts the power output from the motor into the reciprocating forward and reverse rotation of the brush bristles 3 along the axial direction through eccentric rotation. This allows for continuous and stable cleaning without requiring the user to manually push the brush repeatedly and significantly, thereby greatly reducing labor intensity and improving cleaning efficiency.

[0028] The bristle component 3 is oscillatingly mounted on the main body 1. Through eccentric rotation, the bristle component 3 can automatically shift its position upward and engage eccentrically during the cleaning process. This allows it to penetrate deep into irregular areas such as skin and crevices while maintaining a uniform fit, making it suitable for deep cleaning needs of various parts of the body. Furthermore, the drive and transmission components are integrated into the compact main body 1. Combined with the ergonomic handle 2, users can hold it firmly with one hand and easily start and stop the machine, making it simpler and more convenient to use. The internal transmission layout of the main body 1 is reasonable, the connections between various structural components are reliable, and assembly and disassembly are convenient.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, under the transmission of the transmission assembly, the bristle component 3 rotates at an acute angle in the forward direction along the axial direction and also rotates at an acute angle in the reverse direction along the axial direction. Thus, by rotating the bristle component 3 within the acute angle range, and through this reciprocating rotation, not only can hair be effectively prevented from getting caught, but it can also penetrate deeper into the skin texture of any area, effectively removing stubborn dirt and deposits, improving the thoroughness of cleaning. This eliminates the need for high-speed full-circle rotation, greatly reducing the risk of damage during use.

[0030] Preferably, the acute angle is between 30° and 55°. An angle range of 30° to 55° is sufficient to allow the bristles to penetrate deep into the skin's texture or crevices to effectively remove stubborn dirt, while also preventing excessive tilt from resulting in too small a contact area between the bristles and the surface, thus maintaining a good fit and more even cleaning.

[0031] It should be noted that in this embodiment, when the bristle component 3 performs eccentric oscillation, it is specifically driven by the swing shaft 9 mentioned below to perform reciprocating oscillation, so as to achieve better transmission connection and better sealing and waterproofing. Obviously, the front end face of the main body 1 is specifically designed to avoid the hole space between the swing shaft 9 and the bristle component 3 during oscillation, so as to allow the bristle component 3 to freely perform rotational oscillation.

[0032] Alternatively, in other embodiments, the main body may have a rotating disk (not shown) rotatable relative to the axial direction at its front end, with the bristles eccentrically mounted on the rotating disk. In this way, by directly rotating the rotating disk axially and eccentrically mounting the bristles, continuous circular motion can be efficiently converted into reciprocating eccentric oscillation, eliminating the need for additional connecting rods or crank mechanisms. This results in a simple transmission path, minimal energy loss, and improved power utilization. It should be noted that the eccentricity of the bristles is determined by the position of the mounting holes on the rotating disk. By simply changing or correcting the eccentricity, the oscillation angle and stroke of the bristles on the main body can be flexibly adjusted to meet different cleaning intensities and depths.

[0033] In this embodiment, a flexible silicone 4 is sleeved between the bristle component 3 and the rotating component. The flexible silicone 4 serves as a buffer element between the bristle component 3 and the rotating component, effectively absorbing vibrations generated by eccentric oscillations, reducing noise and impact during operation, and making the equipment run more smoothly and quietly.

[0034] Furthermore, the handle 2 is attached to the lower end of the main body 1 via a shock-absorbing soft rubber 5. The shock-absorbing soft rubber 5 at the handle 2 further isolates the mechanical vibration transmitted from the drive assembly to the handle 2, resulting in almost no noticeable shaking when the user holds it, significantly reducing hand fatigue caused by prolonged use.

[0035] In this embodiment, the drive assembly includes a brushless motor 6. Obviously, compared to other motors, the brushless motor 6 eliminates carbon brush friction, resulting in higher efficiency, lower heat generation, and a significantly longer service life, reducing maintenance and replacement costs. Furthermore, by using the brushless motor 6 in conjunction with electronic commutation and a controller, precise forward and reverse switching can be achieved. The drive assembly responds quickly and operates smoothly, allowing users to flexibly control the cleaning direction.

[0036] In this embodiment, the transmission assembly includes a rotor 7 docked to the brushless motor 6, a rocker arm 8 eccentrically connected to the rotor 7, and a swing shaft 9 rotatably connected to the rocker arm 8. The swing shaft 9 is connected to the brush bristles 3 for driving them to rotate freely in either direction. On one hand, the rotor 7 directly docks to the output shaft of the brushless motor 6, and the eccentric rocker arm 8 is integrally eccentrically connected to the rotor 7, resulting in a simple structure, short transmission chain, low power loss, and high energy utilization. On the other hand, the rocker arm 8 drives the swing shaft 9 to transmit power to the brush bristles 3, transforming continuous rotation into regular reciprocating oscillation under eccentric action, resulting in stable torque output and avoiding severe vibration or sudden impact. Furthermore, the multiple eccentric settings eliminate the need for additional connecting rods or complex mechanisms, resulting in a small overall size and light weight. Assembly is simple, requiring only the installation, alignment, and tightening of the rocker arm 8 and swing shaft 9.

[0037] Furthermore, the rotor component 7 is provided with an eccentric shaft 10, and the rocker arm component 8 is rotatably connected to the eccentric shaft 10. The eccentric shaft 10 is directly integrated with the rotor component 7, eliminating the need for additional intermediate connecting rods or supports, thus reducing the number of parts and assembly steps, resulting in a more compact and reliable structure. Since the rocker arm component 8 rotates directly around the eccentric shaft 10, its eccentric motion is smoother and more consistent, effectively suppressing accumulated errors and secondary vibrations caused by multi-stage linkages, and reducing operating noise and impact.

[0038] The swing shaft 9 is eccentrically positioned at the end of the swing arm 8 furthest from the eccentric shaft. This eccentric arrangement at the other end of the swing arm 8 results in a longer lever arm from the eccentric shaft 10 to the swing shaft 9, enabling a larger swing angle and lateral force under the same input torque, thus improving mechanical squeezing and bristle penetration during cleaning. Furthermore, the swing shaft 9's location at the far end of the swing arm 8 allows for a more efficient distribution of mass and inertia, bringing the center of inertia closer to the center during eccentric motion. This reduces the overall vibration amplitude, resulting in a smoother swing and improved user comfort.

[0039] like Figure 3 As shown, in this embodiment, the rear end of the main body 1 is provided with an end cap 11 and a motor bracket 12, and the brushless motor 6 is mounted on the motor bracket 12. It can be understood that the motor bracket 12 provides a support platform for the brushless motor 6, ensuring the coaxiality of the output shaft and the transmission components, avoiding vibration and wear caused by eccentricity or tilting, and improving operational stability. Furthermore, the end cap 11 and the motor bracket 12 can be quickly fixed to the rear end of the main body 1 via threads or clips, allowing the brushless motor 6 to be disassembled without dismantling the front-end power and transmission structures, simplifying assembly and maintenance processes, and significantly reducing downtime maintenance costs.

[0040] Furthermore, multiple soft rubber pads 16 are arranged in a regular pattern on the outer periphery of the motor bracket 12, and the soft rubber pads 16 abut against the inner shell wall of the main body 1.

[0041] In this embodiment, the shower brush also includes a circuit board 13 mounted on the motor bracket 12. The handle 2 is equipped with a battery 14 and a button 15, and the circuit board 13 is electrically connected to the brushless motor 6, the battery 14, and the button 15, respectively. Obviously, the circuit board 13 serves as the main control board, corresponding to the implementation of circuit control, such as power on / off, power adjustment, etc., all of which are existing technologies and will not be described in detail here.

[0042] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
