The connection head 402 is assembled on the threaded interface of the connection column 401 by threaded matching, thereby realizing the detachable assembly between the upper brush body 202 and the brush head 203. It is worth noting that the brush head 203 in this embodiment is fixed by the positioning portion 405. It is connected to a connecting head 402, a telescopic button 405a is installed on the side wall of the positioning part 405, and a positioning hole 401a is opened on the side wall of the connecting column 401. When the brush head 203 is threadedly assembled on the upper brush body 202, when the telescopic button 405a enters the positioning hole 401a, the threaded connection is in place, and at this time the bristles on the brush head 203 are located on the side away from the pressing part 102. The positioning mechanism composed of the telescopic button 405a and the positioning hole 401a can accurately position the brush head 203, thereby ensuring the use effect of the toothbrush. Example 4

[0050] Since the brush head 203 and the upper brush body 202 in the second and third embodiments are detachably assembled, there is a gap between the brush head 203 and the upper brush body 202. In order to prevent water from remaining in the gap and causing bacteria to grow, a sealing component 500 is further provided on the brush head 203 in this embodiment. Figure 6 、 Figure 7 as well as Figure 8 As shown, in this embodiment, the sealing component 500 is a sealing sleeve 501 made of elastic rubber and in a thin film state. When the sealing sleeve 501 is not in use, the sealing sleeve 501 is as shown in FIG. Figure 7 As shown, the brush head 203 is rolled up. When the brush head 203 is assembled on the upper brush body 202, the sealing sleeve 501 is turned over and covered on the connecting component 400. The effect is as follows: Figure 8 As shown, the gap between the brush head 203 and the connecting component 400 is sealed, which avoids the problem of water entering the gap and breeding bacteria during brushing, ensures the dryness and cleanliness of the toothbrush, and improves the environmental hygiene effect of the toothbrush.
