Description

Rotary electric interdental brush and its fixing device

The rotary electric tooth gap brush and the fixing device thereof are combined with the rotary tooth gap brush head and the body; the interlocking brush head is internally provided with a linkage device for driving the rotation of the fixing device disk body, and the fixing device is a lower fixing seat and The disc-shaped combination of the upper fixing cover is provided with a fixing groove for loading and unloading the tooth-scratch brush in a limited space, and the interdental brush is fixed on the fixing device and driven by the linkage device in the tooth-brushing head of the body. The scrubbing action of rotating or reciprocating rotation.

The conventional electric interdental brush is powered by a vibrating device, which only makes the interdental brush vibrate and clean the tooth gap; the vibrating method of cleaning the interdental seam is as effective as the vibrating toothbrush cleaning, and the softness of the bristles itself makes it The point of contact with the teeth does not have much movement in the vibration, especially when the force is applied, so it is difficult to achieve the purpose of effective tooth cleaning; in addition, even the most flexible hand directly handles the manual interdental brush, on both sides And the part of the teeth in the back row is limited by the space of the cheeks, not only the brush distance of the front and rear brush is small, but it is more difficult to rotate the interdental brush.

The invention relates to a rotary electric interdental brush and a fixing device thereof; the rotary electric interdental brush system comprises a body, an interdental brush head and a fixing device, and the body of the electric toothbrush of the system is a source of power for the grip. Usually, the body is equipped with an electric motor, and the motor drives a driving shaft to perform a rotary motion or a reciprocating motion, and the dental brush head and the electric toothbrush head are One end of the sample device is connected to the body power source at one end, and the fixed device disk body is connected to the other end, and the linkage device is a bevel gear set or a connecting rod (one of which is used as an embodiment for convenience), so as to push the fixing device The disk body is rotated.

The fixing device is a combination of a lower fixing seat and an upper fixing cover on the interdental brush head, and the lower fixing seat is pivoted on the shaft of the interdental brush head, and is driven by the power mechanism in the interdental brush head to rotate, and the lower fixing seat is arranged The L-shaped fixing groove having the axial and horizontal intersection of the interdental brush and the lateral sliding groove of the fixing cover, the upper fixing cover has a sliding block and a slot for allowing the axial fixing groove of the interdental brush to penetrate through, The slot is formed by a hole extending toward one side and extending into a horizontal side groove, so that the upper fixing cover is laterally moved on the lower fixing seat to open and close the horizontal fixing groove of the lower fixing seat, so as to facilitate quick replacement of the interdental brush; The fixed cover has a convex bamboo shoot on the side of the slot, the convex bamboo shoot is fitted into the axial fixed fixed slot of the lower fixed seat, and one is used as the positioning card for the left and right movement of the upper fixed cover, and then the embedded card is inserted into the fixed slot. The interdental brush in the middle is forced to tighten.

Please refer to the first figure; the rotary electric interdental brush and its fixing device (hereinafter referred to as the present creation) comprise a body 50, an interdental brush head 40 and a fixing device 1; the body 50 is a grip and a source of power. The interdental brush head 40 is coupled to the body 50. The disc body of the end of the interdental brush head 40 is a fixing device 1. The interdental brush 10 is clamped on the fixing device 1, and the interdental brush 10 is attached to the fixing device disc. Rotate or reciprocate rotary motion.

2 is a schematic diagram of the operation of the present invention; wherein the fixing device 1 is composed of an upper fixing cover 20 and a lower fixing seat 30, and the upper fixing cover 20 can be moved left and right on the lower fixing base 30, the upper fixing cover There is a side groove 24 on the upper side, and the side groove is aligned with the fixing groove 31 of the lower fixing seat to remove or load the interdental brush 10.

The third figure shows a three-dimensional exploded and partial structural cross-sectional view of the present embodiment: the fixing device 1 is mounted on the front end of the interdental brush head 40, and the structure of the interdental brush head 40 is similar to that of the electric toothbrush head, and an end is provided with an axis. 41, the end of the structure has a buckle 411 structure, in the embodiment of the linkage device 43 is a link 431, the rod end is biased to one side of the shaft, the lower part of the fixing device 1 under the fixing device 30 The shaft head 34 is disposed at the bottom of the brush head structure and the linkage device of the conventional electric toothbrush, so that the lower fixing seat is pivoted on the shaft 41, and a horizontal C-shaped groove 33 is disposed at the lower end of the lower fixing base 30. A C-clip 42 is inserted therein, and the shaft clamping hole 421 at one end thereof is clamped on the buckle groove 411 at the end of the shaft 41; the lower fixing seat is fixed to the interdental brush head 40, and only the shaft is rotated, and the lower fixing seat is fixed. The bottom end has a connecting rod hole 35 corresponding to the connecting rod 431, and the connecting rod is reciprocating, such as a rocking rocker, the end of which is embedded in the connecting rod hole 35, and the upper half of the lower fixing base 30 The part is a structural device for fixing the interdental brush, and the lower fixing seat 30 is provided with an axially and horizontally intersecting L-shaped interdental brush fixing groove (31, 311). And the lateral sliding groove 32, the upper fixing cover 20 is correspondingly provided with a sliding block 22 and a slot 21 of the axial fixing groove 31. The slot 21 is formed in a hole shape and one end extends to one side to form a horizontal side slot. 24, the upper fixing cover 20 is laterally moved on the lower fixing base 30, with the side groove 24 aligned with the fixing groove 31 as an operation of filling or taking out the interdental brush 10.

The assembly and use of the present invention is as shown in Figs. 4 to 7; pushing the upper fixing cover 20 to the right (as shown in the fourth figure), and the axial fixing groove 31 of the interdental brush is pushed to the upper fixing cover slot 21 The left end, at this time, the side groove 24 of the upper fixing cover 20 is aligned with the axial fixing groove 31 and the horizontal fixing groove 311 of the lower fixing seat, and the fixed position of the interdental brush fixing end 11 of the lower end of the interdental brush 10 can be inserted into the horizontal fixing of the lower fixing seat. In the slot 311 (the interdental brush 10 that has not been activated is usually straight, the center rod is straight) (as shown in the fifth figure); then the interdental brush 10 is pulled up to fit into the axial fixing slot 31 (as shown in the sixth figure) Then, the upper fixing cover 20 is pushed back to the left, as shown in the seventh figure, the open end of the axial fixing groove 31 is closed, that is, the end of the interdental brush 10 is bent for a short section and then clamped to Fixing device 1.

The upper fixing cover 20 has a convex bamboo shoot 23 which is inwardly ridged on one side of the slot 21, and the convex bamboo 23 is fitted into the opening of the lower fixing seat axial fixing groove 31, and can be used as an upper fixing cover. The positioning card for moving left and right, and then the interdental brush 10 forcibly tightening in the fixing groove 31 can be added.

The creation of the rotary electric interdental brush and its fixing device, the simple and lightweight interdental brush fitting mechanism is constructed in a limited space, and the operation is also convenient, and the tooth cleaning is easy to handle. The tooth movement is a novel and beneficial work.
