[0048] like Figure 1-4 As shown, the self-illuminating electric cleaning brush includes a handle-type main unit 100 and a cleaning brush head 200 detachably connected to the handle-type main unit 100. The handle-type main unit 100 includes a main unit housing 101 and an internal drive motor 102. The cleaning brush head 200 includes a brush element 201 and a brush neck 202, which has a transmission structure disposed therein. The drive motor 102 drives the brush element 201 to rotate via the transmission structure.

[0049] The central axis of the brush 201 forms an obtuse angle with the extension axis of the main body housing 101. The brush 201 is tilted upward toward the front side relative to the main body housing 101 located below.

[0050] The front side of the main body housing 101 is provided with a protruding mounting seat 1 and an illuminating portion 2. The intersection of the center line of the illuminating portion 2 and the center axis of the brush 201 is located at the front side of the brush 201.

[0051] More specifically, the upper portion of the mounting base 1 has an inclined reference surface a that slopes from top to bottom and from inside to outside, and the lighting unit 2 is disposed on the inclined reference surface a. The intersection of the normal extension of the inclined reference surface a and the central axis of the brush 201 is located outside the front side of the brush 201.

[0052] During use, the user holds the handle-type main unit 100, and aligns the cleaning brush head 200 with the object to be cleaned. The structure in which the central axis of the brush 201 forms an obtuse angle with the extended axis of the main unit housing 101 is more ergonomic, making it easier to hold for a long time. It is also more suitable for cleaning narrow spaces, avoiding interference from the head and handle, reducing cleaning dead angles, and improving the cleaning effect. A mounting base 1 with an inclined reference surface a is provided on the front side of the main unit housing 101 to set the lighting unit 2, ensuring that the lighting unit 2 can always illuminate the front of the brush 201 during the cleaning process, can more accurately illuminate the cleaning area, avoid light being blocked by the brush 201, improve visibility, and enable users to accurately perform cleaning operations even in low-light environments without the need for external lighting tools, making it more convenient to use.

[0053] In this embodiment, the cleaning brush head 200 is detachably connected to the handle-type main unit 100. Users can quickly swap out different types of cleaning brush heads 200, such as fine-bristle brushes, hard-bristle brushes, and sponge brushes, to suit different cleaning scenarios. Furthermore, the detachable design allows users to easily remove the cleaning brush head 200 for cleaning and maintenance, extending the product's lifespan. If the cleaning brush head 200 becomes worn or damaged, users only need to replace the brush head, eliminating the need to purchase the entire cleaning brush, thus reducing overall costs.

[0054] like Figure 1 As shown, the normal extension line of the inclined reference surface a does not intersect with the brush member 201 , and the light radiated by the lighting portion 2 falls on the front area of ​​the cleaning brush head 200 .

[0055] like Figure 4-5 As shown, the mounting base 1 and lighting unit 2 are integrally formed as a plastic component 10, with the lighting unit 2 being a spherical light guide. A light-emitting element 3 is housed within the plastic component 10, and light from the light-emitting element 3 is radiated outward through the spherical light guide. The mounting base 1 and lighting unit 2 are integrally formed using plastic injection molding technology, forming a seamless, continuous structure. This improves the lamp's waterproof and dustproof properties, overall strength, and lifespan. The spherical light guide design allows light to be reflected multiple times internally, resulting in more uniform outward radiation and avoiding light spots and shadows.

[0056] like Figure 5 、 9As shown, the light-emitting element 3 is a SMD lamp bead. Opposing ribs b are provided on the inner wall of the mounting base 1. Ribs b have opposing notches c, into which the SMD lamp bead's plate is inserted. A space is formed above ribs b to accommodate the SMD lamp bead.

[0057] Since the lighting part 2 is a spherical light and the light is very weak, it is preferred that the light emitted from the lighting part 2 is green light or purple light, so as to improve the dust display effect.

[0058] like Figure 2-3 As shown, the front surface Z of the main body housing 101 is a curved surface structure that bulges outward, and the outer surface of the mounting base 1 is a beveled semi-cylindrical surface J. This structural arrangement of the main body housing 101 is more suitable for holding. In addition, the rear side of the handle-type main body 100 is provided with a button R for controlling the rotation of the brush 201 and turning the light on and off.

[0059] like Figure 5 As shown, plastic component 10 has a cavity open to the rear. The front surface of the main unit housing 101 is provided with a through hole d that connects to the main unit's internal cavity. The edge of through hole d is provided with a connecting portion e that connects to the annular recessed edge of the opening of plastic component 10. Plastic component 10 is connected to the main unit housing 101 via connecting portion e, and the cavity communicates with the main unit's internal cavity.

[0060] Preferably, since the lighting portion 2 of the plastic component 10 has special material property requirements, it is generally not integrally injection molded with the main body housing 101. Therefore, connecting them together through ultrasonic welding is a preferred solution, which can achieve seamless connection.

[0061] like Figure 5-7 As shown, a connection portion 20 is provided at the upper end of the handle-type main unit 100. The connection portion 20 includes a connecting column 21 located in the middle. The transmission output end V of the drive motor 102 is provided in the connecting column 21. A connecting hole 30 is provided at the bottom of the brush neck 202 of the cleaning brush head 200. The connecting column 21 is inserted into the connecting hole 30. A transmission docking portion 40 is provided in the connecting hole 30 to dock with the transmission output end V. The transmission output end is spline-shaped, and a spline hole L is provided in the transmission docking portion 40. When the drive motor 102 rotates, the transmission output end drives the transmission docking portion to rotate synchronously. Then, the gear assembly in the transmission mechanism switches the direction of the rotation, thereby driving the brush element 201 to rotate around its central axis.

[0062] like Figure 5 、 7As shown, the connecting post 21 is provided with a longitudinal guide groove m and a transverse limit groove n located at one side of the bottom of the longitudinal guide groove m and connected thereto. The wall of the connecting hole 30 is provided with a limit protrusion s that matches the longitudinal guide groove m and the transverse limit groove n. During relative rotation between the cleaning brush head 200 and the handle-type main unit 100, the limit protrusion s can smoothly move along the longitudinal guide groove m and automatically slide into the transverse limit groove n when reaching a specific position, thus achieving a stable connection and convenient assembly and disassembly. This design not only improves the user experience but also ensures safety and stability during use.

[0063] like Figure 5 、 8 As shown, an annular decorative wall y is provided on the periphery of the connecting column 21, and an annular slot k is formed between the annular decorative wall y and the connecting column 21. An annular inner recess g is provided on the outer periphery of the lower end of the brush neck 202. A latching tongue p is provided on the inner wall of the annular decorative wall y, and a latching hole q is provided on the annular inner recess g. The latching tongue p is inserted into the latching hole q. After the lower end of the brush neck 202 is inserted into the annular slot k, the annular decorative wall y is engaged with the annular inner recess g. The annular decorative wall y not only improves the aesthetics of the product, but also forms a reliable fixing method by combining the latching tongue p provided on its inner wall with the latching hole q in the annular inner recess g at the lower end of the brush neck 202. This design not only enhances the firmness of the connection part, but also makes the connection between the cleaning brush head 200 and the handle-type host 100 tighter, reducing the risk of loosening or falling off due to external forces.

[0064] like Figure 6 、 7 As shown, the bottom of the annular slot k is provided with an arc-shaped limiting recess h, and the bottom of the brush neck 202 is provided with a rotation limiting protrusion f. The arc-shaped limiting recess h and the rotation limiting protrusion f cooperate to limit the relative rotation angle between the cleaning brush head 200 and the handle-type main unit 100. This design not only ensures operational accuracy and comfort during use, but also prevents structural damage or functional failure caused by excessive rotation.
