[0035] A toothbrush head comprises a brush head body 1, a bristle plate 2 and bristles 3. The brush head body 1 is provided with a cavity 11 for accommodating the bristle plate 2. The bristle plate 2 is snap-connected with the brush head body 1. The bristle plate 2 can move relative to the brush head body 1. The bristles 3 are provided on one surface of the bristle plate 2.

[0036] Embodiment 1, as Figure 1-Figure 4 As shown, a plurality of buckles 12 are provided on the inner wall of the cavity 11; the bristle plate 2 includes a plate surface 21 for implanting bristles 3, and the bristle plate 2 is provided with a plurality of first slots 23 engaged with the buckles 12, the plate surface 21 is made of elastic material, and the plate surface 21 is concave downward, and bristles 3 are provided on one surface of the plate surface 21.

[0037] The bristle plate 2 further includes a support column 22 . The other side of the plate surface 21 is provided with a support column 22 . The length of the support column 22 is smaller than the distance from the contact surface between the plate surface 21 and the support column 22 to the bottom of the cavity 11 .

[0038] When the plate surface 21 is subjected to pressure, the side of the plate surface 21 where the bristles 3 are provided becomes concave inward, so that the bristles 3 wrap around the upper surface of the teeth and the sides of the teeth that are difficult to brush, and can efficiently fit the teeth. The contact area between the bristles 3 and the teeth is increased, and the cleaning ability is strong. At this time, the support column 22 arranged under the plate surface moves downward until it abuts against the bottom of the cavity 11. The support column 22 can limit the downward depression of the plate surface 21.

[0039] Embodiment 2, as Figure 5-Figure 8 As shown, the difference from the first embodiment is that the plate surface 21 is convex upward.

[0040] Embodiment three, as Figure 9-12 As shown, a plurality of rotating shafts 14 and a plurality of first steps 15 are provided on the inner wall of the cavity 11, and the rotating shaft 14 is cylindrical; the bristle plate 2 includes two rotating blocks 24 and an elastic element 25, and a plurality of second slots 26 engaged with the rotating shaft 14 are provided on the bristle plate 2, and bristles 3 are provided on one surface of the rotating block 24, and the other surface of the rotating block 24 is in contact with the elastic element 25, and the rotating block 24 can rotate along the rotating shaft 14.

[0041] A plurality of first positioning columns 16 are disposed at the bottom of the cavity 11 . The elastic element 25 is an elastic support sheet 251 . The elastic support sheet 251 is provided with positioning holes 2511 that cooperate with the first positioning columns 16 . The elastic support sheet 251 is “H” shaped and made of stainless steel.

[0042] When the rotating blocks 24 are not subjected to pressure, the ends of the two rotating blocks 24 that are away from each other abut against the first step 15 , and the first step 15 can limit the rotation range of the rotating blocks 24 .

[0043] When the rotating block 24 is subjected to pressure, the ends of the two rotating blocks 24 that are close to each other rotate downward along the rotating shaft 14, and the rotating block 24 transmits the pressure to the elastic support sheet 251 located below the rotating block 24. The elastic support sheet 251 is elastically deformed under the pressure. At this time, the surfaces of the two rotating blocks 24 with bristles 3 simultaneously wrap the upper surface of the teeth and the sides of the teeth that are difficult to brush, which can efficiently fit the teeth, increase the contact area between the bristles 3 and the teeth, and enhance the cleaning ability.

[0044] Embodiment 4, as Figure 13-Figure 16 As shown, a plurality of rotating shafts 14 and a plurality of first steps 15 are provided on the inner wall of the cavity 11, and the rotating shaft 14 is cylindrical; the bristle plate 2 includes two rotating blocks 24 and an elastic element 25, and a plurality of second slots 26 engaged with the rotating shaft 14 are provided on the bristle plate 2, and bristles 3 are provided on one surface of the rotating block 24, and the other surface of the rotating block 24 is in contact with the elastic element 25, and the rotating block 24 can rotate along the rotating shaft 14.

[0045] A plurality of second positioning posts 17 are disposed at the bottom of the cavity 11 . The elastic element 25 is a spring 252 , and the spring 252 cooperates with the second positioning posts 17 .

[0046] When the rotating blocks 24 are not subjected to pressure, the ends of the two rotating blocks 24 that are away from each other abut against the first step 15 , and the first step 15 can limit the rotation range of the rotating blocks 24 .

[0047] When the rotating block 24 is subjected to pressure, the ends of the two rotating blocks 24 that are close to each other rotate downward along the rotating shaft 14, and the rotating block 24 transmits the pressure to the spring 252 located below the rotating block 24. The spring 252 is elastically deformed under the pressure. At this time, the surfaces of the two rotating blocks 24 with bristles 3 simultaneously wrap the upper surface of the teeth and the sides of the teeth that are difficult to brush, which can efficiently fit the teeth, increase the contact area between the bristles 3 and the teeth, and enhance the cleaning ability.

[0048] Embodiment 5, as Figure 17-Figure 20 As shown, a second step 19 is provided on the inner wall of the cavity 11, and a snap-in groove 110 is provided at the bottom of the cavity 11; a spherical snap 27 that engages with the snap-in groove 110 is provided on one side of the bristle plate 2, and bristles 3 are provided on the other side of the bristle plate 2.

[0049] The bristle plate 2 can rotate within a certain range through the cooperation between the spherical buckle 27 and the clamping groove 110, and the second step 19 can limit the rotation range of the bristle plate 2. When the user uses it, since the bristle plate 2 can rotate within a certain range, the side of the bristle plate 2 with the bristles 3 can always fit the surface of the teeth, the contact area between the bristles 3 and the teeth is increased, and the cleaning ability is enhanced.

[0050] The above shows and describes the basic principle, main features and advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, simple changes and substitutions by ordinary technicians in this field are within the protection scope of the utility model.
