Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] like Figures 1 to 3 The floating pressure-relieving brush head shown includes a main brush plate 1 and at least one floating brush plate 2, wherein bristles 4 are planted on the top surface of the main brush plate 1 and the top surface of the floating brush plate 2. The floating brush plate 2 is distributed on the side of the main brush plate 1. The included angle A at the intersection of the extension lines of the main brush plate 1 and the floating brush plate 2 is an obtuse angle. There is a gap between the floating brush plate 2 and the main brush plate 1. The main brush plate 1 and the floating brush plate 2 are connected by a connector 3. The main brush plate 1, the floating brush plate 2 and the connector 3 are all made of deformable material. The thickness of the connector 3 is less than the thickness of the main brush plate 1 and the floating brush plate 2. An installation cavity 5 is formed between the main brush plate 1, the floating brush plate 2 and the connector 3. An elastic brush plate sleeve 6 is fitted inside the installation cavity 5.

[0019] In use, the brush head of this invention features an obtuse angle at the intersection of the extended lines of the main brush plate 1 and the floating brush plate 2, resulting in an overall arc shape. The main brush plate 1 and the floating brush plate 2 maintain a fixed bending angle, allowing the brush head to better conform to the arc-shaped structure of human teeth. Especially when cleaning molars, the deformable main brush plate 1 and floating brush plate 2 easily conform to the tooth surface, facilitating deeper penetration into the oral cavity for thorough cleaning of the molars, thus improving cleaning efficiency and effectiveness. The main brush plate 1, floating brush plate 2, and connecting piece 3 in this application are all made of deformable material, specifically PP material. This ensures the deformability of the main brush plate 1, floating brush plate 2, and connecting piece 3 while also guaranteeing the safety of the brush head during use. When cleaning teeth, the brush head deforms according to the curvature of the tooth surface and the brushing force, providing a floating and pressure-relieving effect while better conforming to the teeth, thus improving the comfort and cleaning efficiency of toothbrush cleaning. In this application, the elastic brush plate sleeve 6 improves the overall integrity and structural strength between the main brush plate 1 and the floating brush plate 2, extending their service life. The elastic brush plate sleeve 6 is made of soft rubber material, specifically TPR, silicone, or TPE. When the main brush plate 1 and the floating brush plate 2 deform according to the curvature of the tooth surface and the brushing force, the elastic brush plate sleeve 6 helps to reduce the up-and-down floating effect of the main brush plate 1 and the floating brush plate 2, achieving a pressure-relieving effect on the teeth and improving the comfort and safety of the toothbrush during use.

[0020] The angle between the intersection of the extended lines of the main brush plate 1 and the floating brush plate 2 in this application is 150-179°. The angle at the intersection of the main brush plate 1 and the floating brush plate 2 can be adjusted according to user needs to improve the fit between the brush head and the tooth surface and increase the efficiency of tooth cleaning.

[0021] The main brush plate 1, the floating brush plate 2, and the connector 3 described in this application are integrally formed, which helps to improve the integrity and structural strength of the brush head; and the thickness of the connector 3 is less than the thickness of the main brush plate 1 and the floating brush plate 2, which facilitates the deformation of the main brush plate 1 and the floating brush plate 2, improves the flexibility of the brush head during use, and makes it easier for the brush head to fit the tooth surface more closely.

[0022] Example 1: like Figures 3-6 As shown, there are two floating brush plates 2 in this embodiment, namely an upper floating brush plate 201 and a lower floating brush plate 202. The upper floating brush plate 201, the main brush plate 1 and the lower floating brush plate 202 are distributed in an upper, middle and lower manner. The upper floating brush plate 201 and the main brush plate 1 are connected by an upper connector 301. An upper mounting cavity 501 is formed between the upper floating brush plate 201, the main brush plate 1 and the upper connector 301. An upper elastic brush sleeve 601 is provided in the upper mounting cavity 501. The main brush plate 1 and the lower floating brush plate 202 are connected by a lower connector 302. The lower floating brush plate 202, the main brush plate 1 and the lower connector 302 form a lower mounting cavity 502. A lower elastic brush sleeve 602 is provided in the lower mounting cavity 502. The upper elastic brush sleeve 601 and the lower elastic brush sleeve 602 are connected by an elastic brush plate connector 603. The elastic brush plate connector 603 is disposed in the groove 8 on the main brush plate 1, the upper floating brush plate 201, and the lower floating brush plate 202. The groove 8 limits the elastic brush plate connector 603, improving the installation and fixation of the elastic brush plate connector 603 on the brush head. The upper elastic brush sleeve 601, the lower elastic brush sleeve 602, and the elastic brush plate connector 603 are integrally formed to form an elastic brush plate sleeve 6. That is, the upper elastic brush sleeve 601, the lower elastic brush sleeve 602, and the elastic brush plate connector 603 constitute the elastic brush plate sleeve 6, improving the connection tightness between the elastic brush plate sleeve 6 and the main brush head and the upper and lower floating brush heads. Both the upper elastic brush sleeve 601 and the lower elastic brush sleeve 602 are provided with bristles 7, which further improve the cleaning effect on teeth and the pressure-relieving effect during teeth cleaning.

[0023] The upper and lower floating brush plates are designed to move up and down according to the curvature of the tooth surface and the brushing force, corresponding to the upper floating brush plate 201 and the lower floating brush plate 202. This allows the brush head to better fit the tooth surface and improve the cleaning power. The upper elastic brush sleeve 601 and the lower elastic brush sleeve 602 help to improve the overall integrity between the upper floating brush plate 201 and the lower floating brush plate 202, improve the floating pressure effect of the brush head on the tooth surface, and improve the comfort of brushing.

[0024] Example 2: like Figures 7-11 As shown, in this embodiment, there are two floating brush plates 2, namely an upper floating brush plate 201 and a lower floating brush plate 202. The upper floating brush plate 201, the main brush plate 1, and the lower floating brush plate 202 are distributed in an upper, middle, and lower manner. The upper floating brush plate 201 and the main brush plate 1 are connected by an upper connector 301. An upper mounting cavity 501 is formed between the upper floating brush plate 201, the main brush plate 1 and the upper connector 301. An upper elastic brush sleeve 601 is provided in the upper mounting cavity 501. The main brush plate 1 and the lower floating brush plate 202 are connected by a lower connector 302. The lower floating brush plate 202, the main brush plate 1 and the lower connector 302 form a lower mounting cavity 502. A lower elastic brush sleeve 602 is provided in the lower mounting cavity 502. The main brush plate 1 has side wall grooves 101 on both sides. Side elastic brush plate connecting strips 604 are provided in the side wall grooves 101. Each side elastic brush plate connecting strip 604 is connected to the upper elastic brush sleeve 601 and the lower elastic brush sleeve 602 at both ends. The two side elastic brush plate connecting strips 604 cover the two sides of the main brush plate 1. Both side elastic brush plate connecting strips 604 are provided with rubber bristles 7. The upper elastic brush sleeve 601, the lower elastic brush sleeve 602, the elastic brush plate connecting piece 603 and the two side elastic brush plate connecting strips 604 are integrally formed to form an elastic brush plate sleeve 6.

[0025] In this embodiment, the elastic brush plate sleeve 6 improves the tightness and stability of the connection between the main brush head 1 and the upper and lower floating brush heads, which helps to extend the service life of the brush head. At the same time, the elastic brush plate sleeve 6 enables the upper floating brush plate 201 and the lower floating brush plate 202 to float up and down and relieve pressure when brushing teeth.

[0026] Example 3: like Figures 12-15 As shown, in this embodiment, there are three floating brush plates 2: an upper floating brush plate 201, a left floating brush plate 203, and a right floating brush plate 204. The upper floating brush plate 201, the left floating brush plate 203, and the right floating brush plate 204 are distributed on the top, left, and right sides of the main brush plate 1, respectively. The upper floating brush plate 201 is connected to the main brush plate 1 via an upper connector 301, the left floating brush plate 203 is connected to the main brush plate 1 via a left connector 303, and the right floating brush plate 204 is connected to the main brush plate 1 via a right connector 304. The main brush plate 1, the upper floating brush plate 201, the left floating brush plate 203, the right floating brush plate 204, the upper connector 301, the left connector 303, and the right connector 304 form an installation cavity 5, and an elastic brush plate sleeve 6 is fitted inside the installation cavity 5.

[0027] In this embodiment, the upper floating brush plate 201, left floating brush plate 203, right floating brush plate 204, and main brush head 1 are configured such that the brush head is divided into four independent parts. Each of the four independent parts can deform according to the curvature of the tooth surface and the brushing force, achieving multi-directional and angular movement to conform to the tooth surface, realizing a wrap-around cleaning of teeth and hard-to-clean areas such as the gingival sulcus. The elastic brush plate sleeve 6 helps to improve the pressure relief effect of the upper floating brush plate 201, left floating brush plate 203, right floating brush plate 204, and main brush head 1 on the teeth, improving the comfort and safety of the toothbrush during use.

[0028] Example 4: like Figures 16-19As shown, in this embodiment, there are four floating brush plates 2, namely an upper floating brush plate 201, a lower floating brush plate 202, a left floating brush plate 203, and a right floating brush plate 204. The upper floating brush plate 201, the lower floating brush plate 202, the left floating brush plate 203, and the right floating brush plate 204 are respectively distributed on the upper, lower, left, and right sides of the main brush plate 1. The upper floating brush plate 201 is connected to the main brush plate 1 through an upper connector 301, the left floating brush plate 203 is connected to the main brush plate 1 through a left connector 303, the right floating brush plate 204 is connected to the main brush plate 1 through a right connector 304, and the lower floating brush plate 202 is connected to the main brush plate 1 through a lower connector 302. The main brush plate 1, the upper floating brush plate 201, the lower floating brush plate 202, the left floating brush plate 203 and the right floating brush plate 204, the upper connector 301, the lower connector 302, the left connector 303 and the right connector 304 form an installation cavity 5, and an elastic brush plate sleeve 6 is fitted inside the installation cavity 5.

[0029] In this embodiment, the arrangement of the upper floating brush plate 201, lower floating brush plate 202, left floating brush plate 203, right floating brush plate 204, and main brush head 1 divides the brush head into five independent parts. Each of the five independent parts can deform according to the curvature of the tooth surface and the brushing force. The five independent parts can also move in multiple directions and angles, achieving a wrap-around cleaning of teeth and hard-to-reach areas such as the gingival sulcus. The elastic brush plate sleeve 6 helps to improve the overall integrity of the brush head, achieve a pressure-relieving effect on the teeth, and improve the comfort and safety of the toothbrush during use.
