Description

Toothbrush structure

This creation is about oral cleaning products, especially toothbrushes used to wash plaque on the surface of teeth to prevent dental caries.

The cleaning of the oral cavity is that the Chinese have been taught personal hygiene habits since childhood. From the early advocacy of early morning and the concept of brushing before bedtime, until now, the relevant research organizations have suggested increasing the brushing after eating, and using mouthwash and floss in time to remove most of the Bacteria attached to the surface of the teeth to prevent excessive plaque growth and affect oral health. Due to the frequent use of the toothbrush and the residual bacteria after each use, the use of a toothbrush filled with bacteria adversely affects the cleaning of the oral cavity. Related research articles report that the life of the toothbrush should not be too long, and it is even better to replace the new product month by month. Especially the place where the toothbrush is placed is in the wet bathroom, which is undoubtedly the best place for bacterial growth and reproduction.

Most toothbrushes have a one-piece structure, mainly relying on a plurality of bundles of bristles on one end of the toothbrush to remove the tooth surface. In the face of replacement, the entire abandonment is still required. For example, Taiwan Patent No. M483715 Health Toothbrush, No. M476520 toothbrush with antibacterial layer. However, today's environmental issues are effectively using natural resources to avoid excessive wear and tear. Many related companies have developed related toothbrushes, replacement mechanisms for bristles, or replacement teeth. The brush has a product such as one end of the bristles, and even a cleaning head that can replace the brush head of the toothbrush with a floss type or a surface for cleaning the tongue.

The creation is a toothbrush structure that allows the user to quickly attach the brush head to the handle to replace the old brush head without having to discard the entire toothbrush.

In order to achieve the foregoing objects and effects, the present toothbrush structure includes a handle and a handle, wherein: the handle has a mounting end and a holding end, and the handle is from the mounting end toward the holding end a slot is disposed in a direction, and a side slot of the handle is provided with a side slot connected to the slot, the slot is provided with a track from the mounting end toward the holding end; the handle includes a brush head And a long rod connected to the brush head, the long rod is inserted into the slot of the handle, and the peripheral side of the long rod is provided with a continuous perforation, and an elastic rib is disposed in the hole wall of the through hole, the elasticity The rib is provided with a convex portion which is slid along the rail and is buckled against the side groove, and the convex portion is slid to the rail and the elastic rib is not compressed by the rail.

Please refer to the first to fifth figures of the drawing. The figure shows that the toothbrush structure 1 comprises a handle 2 and a handle 3.

The handle 2 has a mounting end 21 and a holding end 22, and the handle 2 is provided with a slot 23 from the mounting end 21 toward the holding end 22, and the peripheral side of the handle 2 is provided with a communication a slot 24 of the slot 23, the slot 23 is provided with a track 25 disposed from the mounting end 21 toward the grip end 22; the handle 3 includes a brush head 31 and one of the brush heads 31 connected thereto a long rod 32, wherein a surface of one side of the brush head 31 is disposed with a plurality of bundles of bristles 310, which are inserted into the slots 23 of the handle 2 such that the heads 31 are located at the mounting end 21 of the handle 2. The outer side of the long rod 32 is provided with a continuous through hole 33. The inner wall of the through hole 33 is provided with an elastic rib 34. The elastic rib 34 is provided with a convex portion 35 along which the convex portion 35 is attached. After the slipping, the side groove 24 is buckled, and the convex portion 35 is slid to the rail 25 and the elastic rib 34 is not compressed by the rail 25.

Regarding the installation of the present grip 2 and the handle 3, the length of the handle 3 is The rod 32 is inserted into the slot 23 of the handle 2 in the direction of its mounting end 21 and moves toward the grip end 22, during which the projection 35 on the long rod 32 slides along the rail 25 until the projection 35 The buckle is positioned in the side groove 24 to complete. It must be noted that the track 25 of the present invention provides the function of the sliding guide of the convex portion 35 which is not restricted to the convex portion 35, in other words, the rail 25 is not compressed by the compression elastic rib 34.

Please refer to the fifth to seventh figures of the drawing, the toothbrush structure 1 of the present invention further includes the following technical features. The slot 23 is provided with a pressing slope 26, and the pressing ramp 26 is integrally connected between the rail 25 and the side slot 24, and the protrusion 35 is slid toward the side slot 24 via the rail 25 to receive the The pressing slope 26 restricts the compression of the elastic rib 34 by the compression, until the convex portion 35 is disengaged from the pressing slope 26 and is buckled against the side groove 24.

The creating convex portion 35 is fastened to the side groove 24, as shown in the seventh and eighth figures of the drawing. The side groove 24 has opposite two limiting surfaces 241 and a positioning surface connecting the two limiting surfaces 241. 242 , and the positioning surface 242 is oriented toward the mounting end 21 , and the circumferential side of the convex portion 35 is opposite to the two limiting surfaces 241 and the positioning surface 242 . The engagement of the convex portion 35 against the positioning surface 242 has the effect of preventing the handle 3 from being detached from the handle 2 by itself. The convex portion 35 is opposite to the two limiting surface 241. When the bristles 310 on the handle 3 of the toothbrush structure 1 clean the teeth, the radial direction of the long rod 32 of the handle 3 relative to the slot 23 is moderately prevented. Turn.

In addition, the handle 3 is provided with a limiting protrusion 36, and the limiting protrusion 36 is located between the brush head 31 and the long rod 32, and the mounting end 21 of the handle 2 is provided with a limiting recess 27 for The limit projections 36 engage each other and also have a radial rotation preventing the long rod 32 of the handle 3 from rotating relative to the slot 23.

Please refer to the ninth to eleventh drawings of the drawing, which is another embodiment of the present invention, which is different from the above embodiment in that the long rod 32 is laterally convexly provided with at least one anti-rotation bump 37, and the An anti-rotation bump 37 is snapped between the opposing track faces 251 of the track 25. The creation of the second rail surface 251 of the rail 25 is achieved by the at least one anti-rotation bump 37, so that the long rod 32 is stably inserted into the slot 23 and the handle 3 is prevented. The long rod 32 rotates in a radial direction relative to the slot 23. In addition, the through hole 33 is away from the brush head 31 than the at least one anti-rotation protrusion 37; the at least one anti-rotation protrusion 37 is elongated, and the at least one anti-rotation protrusion 37 is the brush head 31. The configuration is set in the direction of the long rod 32.
