The width of the through opening 21 on the red light irradiation ring 2 is larger than the width of the door opening 121 on the upper cover 1.

The bottom plate 3 is a rectangular flat plate with an abdicating groove 31 on the front side, and the outline thereof corresponds to the bottom surface of the upper cover 1. Five groups of fixing clamping seats 36 distributed annularly are arranged on the upper surface of the bottom plate 3 so as to install the red light irradiation ring 2. The width of the abdicating groove 31 on the bottom plate 3 corresponds to the width of the door opening 121 on the upper cover 1, and the depth of the abdicating groove 31 far exceeds the center of the circumference of each clamping seat 36. In order to install the clamping component 4 on the lower surface of the bottom plate 3, a left shaft hole 32 and a right shaft hole 34 are respectively arranged on the left side and the right side of the rear part of the abdicating groove 31 on the bottom plate 3; left and right through

holes

33 and 35 are respectively provided at left and right rear corners of the base plate 3.

The clamping assembly 4 includes a left moon plate 41 bent to the right, a right moon plate 42 bent to the left, a left tension spring 43, and a right tension spring 44. The front part of the left moon-shaped plate 41 is arc-shaped, the waist part is provided with a left pin shaft 411 which extends upwards, and the left pin shaft 411 is rotatably inserted into the left shaft hole 32 of the bottom plate 3.

The shell 6 is a special-shaped box body (or a vertical special-shaped cylinder body) with an upward opening, the cross section of the shell is concave, and the shell corresponds to the bottom plate 3. The left front vertical plate 51, the right front vertical plate 52, the left vertical plate 53, the right vertical plate 54 and the rear vertical plate 55 on the periphery of the shell 6 have the same height and support the bottom plate 3 together. The left inner vertical plate 56, the right inner vertical plate 57 and the rear inner vertical plate 58 on the periphery of the housing 6 abdicating groove 59 are the same in height, and the heights of the left inner vertical plate, the right inner vertical plate and the rear inner vertical plate are lower than the heights of the five

vertical plates

51, 52, 53, 54 and 55 on the periphery of the housing 6, so that abdicating space is provided for the clamping assembly 4 below the bottom plate 3.

The power conversion circuit board 6 is mounted in a space surrounded by five

vertical plates

51, 52, 53, 54, 55 on the outer periphery of the housing 6 and three inner

vertical plates

56, 57, 58 on the outer periphery of the relief groove 59. The circuit on the power conversion circuit board 6 is a direct current power supply with an automatic control function. Referring to fig. 6, the dc power supply includes an ac/dc conversion circuit 61, an ac power supply line 7, and a delay switch circuit 62. The ac power cord 7 is led out from a dedicated cord hole 541 in the right standing plate 54.

The plug 71 of the ac power line 7 outside the housing 5 is detachably connected to the commercial power, the other end of the ac power line 7 inside the housing 5 is electrically connected to the ac input port 611 of the ac-dc conversion circuit 61, the dc output port 612 of the ac-dc conversion circuit 61 is electrically connected to the dc input port 621 of the delay switch circuit 62, and the dc output port 622 of the delay switch circuit 62 is electrically connected to the red LED array 22.

The delay switch circuit 62 includes a controller 623 and a sensor 624 mounted on the base plate 3 for detecting the movement state of the left moon plate 41 (or the right moon plate 42). The dc input port of the controller 623 is the dc input port 621 of the delay switch circuit 62, and the control signal input port of the controller 623 is connected to the signal output port of the sensor 624. The dc output port of the controller 623 is the dc output port 622 of the delay switch circuit 62. The controller 623 determines a signal of the movement of the left moon plate 41 (or the right moon plate 42) from the sensor 624, and controls the ac/dc conversion circuit 61 to supply power to the red LED array 22 on the red light irradiation ring 2.

The red light irradiation ring 2 is arranged on the bottom plate 3, and a through opening on the red light irradiation ring 2 is opposite to the abdicating groove 31 on the bottom plate 3. The housing 6 is mounted below the base plate 3. The upper cover 1 is buckled on the upper surface of the bottom plate 3 and covers the red light irradiation ring 2 on the bottom plate 3 to shield dust and protect the red light irradiation ring 2. The door opening 121 on the front vertical surface 12 of the upper cover 1 faces the relief groove 31 on the bottom plate 3 and the relief groove 59 on the outer shell 6.

In use, the ac power line 7 is connected to mains electricity via the plug 71. When the user holds the handle of the toothbrush and extends the toothbrush vertically to the door opening 121 of the upper cover 1, the relief groove 31 of the bottom plate 3, and the relief groove 59 of the housing 6, when the head of the toothbrush enters the opening 21 of the red light irradiation ring 2, the neck of the toothbrush (shown by the dotted line in fig. 4) will open and enlarge the gap between the front part of the left moon-shaped plate 41 and the front part of the right moon-shaped plate 42 of the holding assembly 4, and at this time, the rear part of the left moon-shaped plate 41 and the rear part of the right moon-shaped plate 42 swing inward at the same time, so as to respectively stretch the left tension spring 43 or the right. When the toothbrush neck reaches the positioning concave positions on the left moon-shaped plate 41 and the right moon-shaped plate 42, the left moon-shaped plate 41 and the right moon-shaped plate 42 are held by the left moon-shaped plate 41 and the right moon-shaped plate 42 due to the tension of the left tension spring 43 and the right tension spring 44, and the toothbrush is fixed. At this time, the neck of the toothbrush is located approximately on the central axis of the red light irradiation circle 2.

The time delay switch circuit on the power conversion circuit board 6 judges that a signal of the action of the left moon-shaped plate 41 or the right moon-shaped plate 42 sent by the sensor arranged on the bottom plate 3 is an opening signal, and controls the alternating current-direct current conversion circuit to supply power to the red light LED array 22 on the red light irradiation ring 2. The red light emitted by the red light LED array 22 irradiates and heats the bristles of the toothbrush to evaporate water on the bristles, so that the effects of drying and preventing the growth of microorganisms are achieved. Since the neck of the toothbrush is set on the central axis of the red light irradiation ring 2, the red LED array 22 on the red light irradiation ring 2 can effectively irradiate the bristles regardless of the orientation of the bristles. After a specified time period, the time delay switch circuit controls the alternating current-direct current conversion circuit to cut off the power supply of the red light LED array 22. The toothbrush can be fixed in the utility model until the next time of tooth brushing.

When the user takes out the toothbrush, the front ends of the left and

right moon plates

41 and 42 are automatically closed by the tension of the left and right tension springs 43 and 44. The time delay switch circuit on the power conversion circuit board 6 judges that the signal sent by the sensor arranged on the bottom plate 3 is a signal for reclosing the left moon plate 41 or the right moon plate 42 according to the state information stored inside, and controls the alternating current-direct current conversion circuit not to supply power to the red light LED array 22 on the red light irradiation ring 2 continuously.

Fig. 5 shows a toothbrush (e.g., a children's toothbrush) having a smaller cross-sectional size neck (shown in phantom) held by left and

right moon plates

41 and 42 on holding assembly 4. In this case, the present embodiment can still correctly perform the above-described functions. And will not be described in detail.

The above description is only for the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and all equivalent changes and modifications made by the technical solutions and the contents of the specification of the present invention should fall within the scope covered by the present invention.
