Description

Technical Field

[0001] This utility model relates to the field of oral hygiene equipment technology, and in particular to a toothbrush head and an electric toothbrush. Background Technology

[0002] Electric toothbrushes achieve efficient cleaning by driving the brush head bristles to vibrate at high frequency through the handle. Because the brush head itself is currently mostly made of plastic, it is relatively lightweight. Therefore, while the bristles vibrate to clean the teeth, the entire brush head also vibrates strongly, causing it to collide with the teeth.

[0003] Current technology typically incorporates a counterweight within the brush head to increase its overall weight. This helps to reduce and balance the brush head's swaying under motor influence, while ensuring the bristles effectively clean teeth, thus providing some shock absorption. However, as users demand higher cleaning performance from electric toothbrushes, the vibration frequency has also increased. Consequently, the shock absorption effect of simply embedding a counterweight within the brush head is limited, resulting in significant impact between the brush head and teeth, negatively affecting the user experience.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] This utility model embodiment provides a toothbrush head 100, such as Figures 1 to 5 As shown, the toothbrush head 100 of this utility model includes a brush head body 1, a counterweight 2, and a bristle assembly 3. One end of the brush head body 1 is provided with a mounting portion 11, and the mounting portion 11 has a receiving groove 111. The counterweight 2 is disposed within the receiving groove 111, dividing the receiving groove 111 into a first groove 1111 and a second groove 1112. The counterweight 2 seals the first groove 1111 to form a shock-absorbing cavity 1113. The bristle assembly 3 is disposed within the second groove 1112, and partially protrudes from the second groove 1112.

[0028] Specifically, the counterweight 2 is disposed within the receiving groove 111. By setting the counterweight 2, the weight of the entire brush head can be increased, thereby reducing and balancing the degree of swaying of the entire brush head body 1 under the action of the motor due to its lighter weight, thus achieving a certain shock absorption effect. Furthermore, the counterweight 2 divides the receiving groove 111 into a first groove 1111 and a second groove 1112, and seals the first groove 1111 to form a shock-absorbing cavity 1113. The sealed gas medium in the shock-absorbing cavity 1113 can absorb and disperse the vibration force received by the brush head body 1, playing a buffering role, thereby effectively reducing the impact force of the brush head body 1 on the teeth and improving brushing comfort. Moreover, since the sealed gas in the shock-absorbing cavity 1113 can absorb vibration, the shock-absorbing cavity 1113 can reduce the sound waves generated by vibration to a certain extent, thereby reducing the noise generated when the brush head vibrates.

[0029] Furthermore, the bristle assembly 3 is disposed within the second groove 1112 and partially exposed outside the second groove 1112, so that the bristle assembly 3 can clean teeth. Specifically, as... Figure 5 As shown, the bristle assembly 3 includes bristles 32 and bristle planting plate 31. The bristle planting plate 31 is disposed in the second groove 1112, and the bristles 32 are disposed on the bristle planting plate 31 and exposed outside the second groove 1112.

[0030] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 2 to 6 As shown, the second groove 1112 is provided with an inner support 4, which is located between the bristle assembly 3 and the counterweight 2, and is sealed to the groove wall of the second groove 1112 to seal the counterweight 2 and the first groove 1111.

[0031] Specifically, the inner support 4 is located between the bristle assembly 3 and the counterweight 2, and is sealed to the wall of the second groove 1112, so that the inner support 4 can seal the counterweight 2 and the first groove 1111. This forms an additional seal outside the shock-absorbing cavity 1113, creating a double seal and ensuring the airtightness of the shock-absorbing cavity 1113. On the other hand, since the counterweight 2 is usually made of metal, the inner support 4 can seal the counterweight 2 and the first groove 1111, thus protecting the counterweight 2 and preventing water from corroding the counterweight 2 outside the brush head body 1.

[0032] Preferably, to prevent water from corroding the counterweight 2 outside the brush head body 1, the counterweight 2 of this utility model is made of stainless steel.

[0033] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 2 to 6 As shown, the counterweight 2 is provided with a connecting groove 21, and the inner support 4 is provided with a connecting protrusion 41, which is inserted into the connecting groove 21.

[0034] Specifically, through the insertion and engagement of the connecting protrusion 41 and the connecting groove 21, a stable connection can be formed between the counterweight 2 and the inner support 4, thereby increasing the stability of the counterweight 2 and the inner support 4 during the operation of the electric toothbrush. Furthermore, during the manufacturing process, the counterweight 2 and the inner support 4 can be pre-connected via the connecting protrusion 41 and the connecting groove 21, allowing the counterweight 2 and the inner support 4 to be stably and conveniently injection molded and installed in predetermined positions within the brush head body 1, ensuring the formation of the shock-absorbing cavity 1113.

[0035] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 4 As shown, a first mounting edge 1112a is provided at the adjacent position of the second groove 1112 and the first groove 1111. The first mounting edge 1112a is arc-shaped and tapers in the direction toward the first groove 1111. The counterweight 2 is fixed to the first mounting edge 1112a.

[0036] Specifically, the first mounting edge 1112a is arc-shaped, which increases the contact area between the counterweight 2 and the first mounting edge 1112a, improves the stability of the connection between the counterweight 2 and the first mounting edge 1112a, and ensures that the counterweight 2 can seal the first groove 1111 to form a shock-absorbing cavity 1113. In addition, the first mounting edge 1112a tapers towards the first groove 1111, so that the counterweight 2 can be more stably fixed on the first mounting edge 1112a.

[0037] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 2 to 5 As shown, the second groove 1112 is further provided with a second mounting edge 1112b on its groove wall. The second mounting edge 1112b is connected to the end of the first mounting edge 1112a away from the first groove 1111, and the inner support 4 abuts against the second mounting edge 1112b.

[0038] Specifically, the second mounting edge 1112b is connected to the end of the first mounting edge 1112a away from the first groove 1111, which makes the structure of the inner support 4 and the counterweight 2 in the groove 111 more compact, reduces the volume occupied by the inner support 4 and the counterweight 2, and avoids the brush head body 1 from being too large.

[0039] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 2 to 5 As shown, the toothbrush head 100 also includes a first housing 12, and the receiving groove 111 is a through groove. The first housing 12 is made of soft rubber material and covers the mounting part 11 to seal one end of the receiving groove 111 near the first groove 1111.

[0040] Specifically, the receiving groove 111 is a through groove, and the first housing 12 covers the mounting portion 11 to seal one end of the receiving groove 111 near the first groove body 1111. Thus, the cavity wall of the damping cavity 1113 on the side away from the counterweight 2 is formed by the first housing 12, which is made of soft rubber material. This helps to further improve the vibration absorption capacity of the damping cavity 1113 and enhance its damping effect. Furthermore, the first housing 12 is made of soft rubber material and covers the mounting portion 11, allowing the first housing 12 to contact the teeth during brushing.

[0041] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 5 As shown, the first housing 12 and the mounting part 11 are integrally formed.

[0042] Specifically, the first housing 12 and the mounting part 11 are integrally formed so that the first housing 12 and the mounting part 11 can be integrally injection molded by injection mold, thereby reducing the assembly steps of the first housing 12 and the mounting part 11, reducing assembly time and cost, and improving manufacturing efficiency.

[0043] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 5 As shown, the first housing 12 and the brush head body 1 are made of transparent material.

[0044] Specifically, the first housing 12 and the brush head body 1 are made of transparent material, allowing users to directly see the internal structure of the toothbrush head 100, increasing the product's aesthetics and making the toothbrush head 100 look more stylish and attractive. Furthermore, it helps users observe the dirt and bacteria that accumulate on the toothbrush head 100 over time, reminding them to replace the toothbrush head 100 regularly and increasing their willingness to do so, thereby ensuring oral hygiene.

[0045] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 2 to 5 As shown, the other end of the brush head body 1 is provided with a mounting groove 13, and a connecting seat 5 is provided in the mounting groove 13. The connecting seat 5 is used for detachable connection of the drive brush handle.

[0046] Specifically, the connection seat 5 allows the toothbrush head 100 to be detachably connected to the drive handle of the electric toothbrush. This allows users to remove the toothbrush head 100 for cleaning and maintenance, reducing bacterial growth. It also facilitates brush head replacement; when the toothbrush head 100 is damaged or worn, only the toothbrush head 100 needs to be replaced instead of the entire electric toothbrush, reducing replacement costs.

[0047] This utility model also provides an electric toothbrush, including the toothbrush head 100 as described above. The beneficial effects of using the toothbrush head 100 in the electric toothbrush have been explained in the description of the toothbrush head 100 above, and will not be repeated here.
