Description

Technical Field

[0001] This utility model relates to the field of toothbrush technology, and more specifically, to an oral care brush with a brush head conversion function. Background Technology

[0002] Toothbrushes are the most common tool in oral care. With the development of technology, electric toothbrushes have been widely used in people's lives. Electric toothbrushes are popular because of their good cleaning effect and ease of use. However, since toothbrush heads generally need to be replaced after 2 to 3 months of use, they are often inserted into the handle and connected by an interference fit. After the handle and brush head are replaced many times, the friction between them decreases, which makes the brush head prone to large wobbling during toothbrush use, making it inconvenient for users. Utility Model Content

[0003] The purpose of this invention is to provide an oral care brush with a brush head conversion function, in order to solve the problem mentioned in the background art that the friction between the brush handle and the brush head will be reduced when they are replaced multiple times, and the brush head will easily wobble.

[0004] This utility model embodiment provides an oral care brush with a brush head conversion function, including a brush handle, a connecting rod, and a brush head. The connecting rod is a detachable structure. The top of the brush handle is provided with a mounting seat that extends through the brush handle. The top of the brush handle is provided with a sleeve outside the mounting seat. The mounting seat is provided with a positioning rod horizontally near the top. The bottom of the brush head is provided with a connecting rod. The bottom of the connecting rod is provided with a mounting sleeve that matches the inner diameter of the sleeve. The bottom of the connecting rod and the mounting sleeve are provided with mounting holes that match the mounting seat. The inner side walls of the mounting holes are provided with sliding grooves and communicating rotating grooves. The mounting sleeve is movably inserted into the inside of the sleeve. The diameter of the connecting rod is the same as that of the sleeve.

[0005] In this embodiment, the mounting sleeve of the connecting rod is aligned with the mounting base and the sleeve, the sliding groove of the mounting hole is aligned with the positioning rod, the mounting sleeve is inserted into the inside of the sleeve, the mounting base is inserted into the inside of the mounting hole, and the sliding groove slides along the positioning rod. When the connecting rod contacts the sleeve, the brush head is rotated, causing the rotating groove to rotate into the positioning rod, thereby fixing the brush head. The connecting rod is detachable for easy replacement of the brush head and the connecting rod.

[0006] In one embodiment of this utility model, a mounting groove is provided on one side of the brush head, and L-shaped locking blocks are provided at the top and bottom of the mounting groove. A mounting plate is movably arranged inside the mounting groove and has grooves evenly provided on one side. A mounting cylinder is arranged inside the groove, and brushes are evenly arranged on one side of the mounting cylinder. U-shaped buckles are provided at the top and bottom of the mounting plate and are fastened to the L-shaped locking blocks. A brush head cover is fastened to one side of the mounting groove.

[0007] In this design, the brush head cover is secured to the L-shaped block by a U-shaped buckle, and the brush head cover is secured to the inside of the mounting groove, preventing bacteria from growing inside the mounting groove. The mounting plate is easy to disassemble and replace with the mounting plate and brush.

[0008] In one embodiment of this utility model, the bottom end of the brush handle is provided with a threaded opening, and a bottom cover is threadedly connected to the threaded opening. A pressing spring is provided in the middle of the bottom cover, and multiple rechargeable batteries are movably arranged inside the brush handle.

[0009] In this design, the bottom cover is connected by a thread, allowing users to easily open it. A pressing spring increases the stability of the battery, which provides a stable power supply.

[0010] In one embodiment of this utility model, an isolation ring is provided at the bottom end of the mounting base, the length of the mounting base is greater than that of the sleeve, and the sliding groove and the rotating groove are both the same size as the positioning rod.

[0011] In this design, the mounting base is supported by an isolation ring. The length of the mounting base is greater than that of the sleeve to provide better stability. The sliding groove and the rotating groove are the same size as the positioning rod, so that the sliding groove and the rotating groove fit tightly with the positioning rod.

[0012] In one embodiment of this utility model, an L-shaped buckle is provided at the top and bottom of one side of the brush head cover, a plurality of protrusions are provided on the back of the brush head, and an anti-slip groove is provided on the surface of the bottom cover.

[0013] In this design, the L-shaped latch makes it easy to pull open the brush head cover, the protrusions increase the massage effect of the brush head inside the mouth, and the anti-slip grooves increase the friction of the bottom cover.

[0014] In one embodiment of this utility model, a switch button is provided on the outer side of the brush handle, and multiple indicator lights are provided at the bottom of the switch button. Both the switch button and the indicator lights are electrically connected to the battery.

[0015] In this solution, the toothbrush can be quickly turned on or off via a switch button, and an indicator light helps users intuitively view the current cleaning status of the toothbrush.
