Description

Technical Field

[0001] The present application relates to the technical field of oral cleaning equipment, and in particular to a brush handle and an electric toothbrush. Background Art

[0002] An electric toothbrush is an electric oral cleaning device that can clean the oral cavity. When using an electric toothbrush to clean the teeth, you only need to press the bristles on the brush head of the electric toothbrush against the teeth, and then use the motor to drive the brush head to vibrate to clean the user's teeth. Compared with ordinary manual toothbrushes, electric toothbrushes are more labor-saving and can achieve better oral cleaning effects.

[0003] However, when cleaning the oral cavity, the vibration intensity caused by the motor vibration is relatively high, and the user will feel obvious vibration when holding the brush handle, which will affect the user's comfort. Utility Model Content

[0004] The present application provides a brush handle and an electric toothbrush, which can effectively reduce the vibration transmitted to the user's palm by the motor component, thereby enhancing the user's comfort.

[0005] In a first aspect, the present application provides a brush handle, comprising: a shell, the shell comprising a head and a bottom arranged opposite to the head; a motor assembly, located in the shell and arranged near the head of the shell; a power supply assembly, located in the shell and arranged near the bottom of the shell, the power supply assembly being electrically connected to the motor assembly for supplying power to the motor assembly; a first soft shock absorber, arranged on the outer periphery of the shell and connected to the shell; and a display part, connected to the shell, the display part being located on the side of the first soft shock absorber close to the head.

[0006] In some embodiments of the present application, the first soft shock-absorbing member is disposed around the outer circumference of the housing. This can increase the contact area between the user's palm and the first soft shock-absorbing member when the user grips the housing, thereby further reducing the vibration transmitted to the user's palm by the motor assembly and enhancing user comfort.

[0007] In some embodiments of the present application, the projection of the first soft shock absorber on the outer circumferential surface of the housing at least partially overlaps with the projection of the motor assembly on the outer circumferential surface of the housing. This allows the first soft shock absorber to directly contact the portion of the housing that is subject to stronger vibrations, thereby achieving a better cushioning and shock-absorbing effect.

[0008] In some embodiments of the present application, the portion of the housing surrounding the motor assembly is a surrounding portion, and the first soft shock absorber is at least partially disposed around the outer periphery of the surrounding portion. This can increase the contact area between the first soft shock absorber and the portion of the housing that is more susceptible to vibration, thereby achieving a better cushioning and shock-absorbing effect.

[0009] In some embodiments of the present application, the length of the housing is L, the distance between the first soft shock absorber and the head along the length of the housing is L1, and the distance between the first soft shock absorber and the bottom along the length of the housing is L2, with 0≤L1≤L / 3 and 0≤L2≤L / 3. This ensures that the distances between the first soft shock absorber and the bottom and the head are moderate, allowing the first soft shock absorber to be positioned in the middle of the housing, facilitating contact with the first soft shock absorber when a user grips the housing.

[0010] In some embodiments of the present application, the housing includes a grip portion located between the head and the base, wherein the radial direction of the grip portion gradually increases as it approaches the head, and / or the radial direction of the grip portion gradually increases as it approaches the base. The grip portion is configured for a user to grip the housing more conveniently and securely, preventing the brush handle from slipping during use.

[0011] In some embodiments of the present application, the first soft shock absorbing member is disposed on the grip portion, so that the first soft shock absorbing member is installed more firmly and prevented from being separated from the housing.

[0012] In some embodiments of the present application, the brush handle further includes a button disposed on the housing, with the first soft shock-absorbing member covering the button. This allows the user to press the button by pressing the first soft shock-absorbing member, thereby alleviating discomfort when pressing the button and improving the user's operating experience.

[0013] In some embodiments of the present application, the distance between the display portion and the head portion is smaller than the distance between the display portion and the bottom portion, so that the user can observe the screen displayed on the display portion while using the electric toothbrush.

[0014] In some embodiments of the present application, the first soft shock-absorbing member includes a first portion and a second portion. In the longitudinal direction of the housing, the first portion is positioned opposite the display portion, while the second portion is offset from the display portion. The length of the first portion along the longitudinal direction of the housing is greater than the length of the second portion along the longitudinal direction of the housing. This can further reduce the vibration transmitted from the motor assembly to the user's palm, thereby enhancing user comfort.

[0015] In some embodiments of the present application, the brush handle further comprises a second soft shock-absorbing member disposed on the outer periphery of the housing and connected to the housing, and the display unit is disposed on the second soft shock-absorbing member. The second soft shock-absorbing member can provide protection for the display unit, reduce vibrations to the display unit, and prevent damage to the display unit due to vibration.

[0016] In some embodiments of the present application, a groove is provided on the outer surface of the second soft shock-absorbing member, and the display unit is located in the groove. This can reduce the overall volume of the brush handle, making it easier to store and carry, and can also cover the side of the display unit, providing better cushioning and shock protection for the display unit.

[0017] In some embodiments of the present application, the distance between the outer side of the second soft shock-absorbing member and the bottom of the groove along the groove depth direction is d1, and the distance between the light-emitting surface of the display portion and the bottom of the groove along the groove depth direction is d2, where d2 < d1. This prevents liquid from splashing onto the light-emitting surface of the display portion and affecting the display effect during brushing.

[0018] In some embodiments of the present application, d3 = d1 - d2, 0.1 mm ≤ d3 ≤ 1.5 mm. On the basis of good protection of the light-emitting surface of the display unit, the light-emitting surface of the display unit is prevented from being hidden too deeply, making it difficult for the user to observe the display screen of the display unit.

[0019] In some embodiments of the present application, a side opening is provided on the outer periphery of the housing, and the second soft shock-absorbing member seals the side opening. The second soft shock-absorbing member can ensure the sealing of the side opening, preventing liquid from entering the housing through the side opening and damaging the electronic components inside the housing.

[0020] In some embodiments of the present application, the bottom portion is provided with a bottom opening, and the brush handle further includes a third soft shock-absorbing member disposed at the bottom portion and sealing the bottom opening. This can reduce the impact of desktop vibration on the brush handle, and the third soft shock-absorbing member is deformed by compression, thereby increasing the contact area with the desktop and the connection stability, making the brush handle more securely placed.

[0021] In a second aspect, the present application also provides an electric toothbrush, comprising a brush head and a brush handle as described in any one of the above embodiments, wherein the brush head is mounted on the brush handle and is transmission-connected to the motor assembly.

[0022] In some embodiments of the present application, the electric toothbrush further comprises: a brush head cover, which is detachably mounted on the brush head to protect the brush head. When the electric toothbrush is not in use, the brush head cover can be used to cover the brush head to prevent dirt from contaminating the brush head.

[0023] The beneficial effects of the present application are: when the user holds the handle of the electric toothbrush to clean the oral cavity, the user can hold the area on the shell where the first soft shock-absorbing part is provided, and the first soft shock-absorbing part contacts the user's palm. The vibration generated by the motor assembly inside the shell when working is transmitted to the user's palm in turn through the shell and the first soft shock-absorbing part. The first soft shock-absorbing part can play an effective buffering and shock-absorbing role, which can effectively reduce the vibration transmitted to the user's palm by the motor assembly, thereby enhancing the user's comfort, and is particularly suitable for children and other users who are more sensitive to vibration; in addition, the display part is located on the side of the first soft shock-absorbing part close to the head, so that when the user holds the brush handle and uses it, the display part is located above the first soft shock-absorbing part, which can prevent the user from blocking the display part when holding the first soft shock-absorbing part, and the user can also observe the picture displayed on the display part more conveniently.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0034] The present application provides a brush handle and an electric toothbrush to solve the problem that when cleaning the oral cavity, the vibration intensity caused by the motor vibration is relatively high, and the user will feel obvious vibration when holding the brush handle, which affects the user's comfort.

[0035] In a first aspect, the present application provides a brush handle, such as Figures 1 to 4 As shown, the brush handle includes a housing 10 , a motor assembly 20 and a power supply assembly 30 .

[0036] Among them, the shell 10 includes a head 11 and a bottom 12 arranged opposite to the head 11. The shell 10 is used to provide support and protection for components such as the motor assembly 20. The overall shape of the shell 10 can be cylindrical, prismatic or other shapes, and this application does not make specific restrictions.

[0037] The motor assembly 20 is located in the housing 10 and is disposed near the head 11 of the housing 10. The motor assembly 20 being disposed near the head 11 of the housing 10 means that the distance between the motor assembly 20 and the head 11 of the housing 10 is less than the distance between the motor assembly 20 and the bottom of the housing 10. The output shaft 21 of the motor assembly 20 extends from the head 11 of the housing 10 and is used to connect with the brush head 80 (such as Figure 6 ) is connected and can drive the brush head 80 to vibrate, so as to use the brush head 80 to clean the oral cavity.

[0038] The power supply assembly 30 is located inside the shell 10 and is arranged near the bottom of the shell 10. The power supply assembly 30 is arranged near the bottom of the shell 10, which means that the distance between the power supply assembly 30 and the head 11 of the shell 10 is greater than the distance between the power supply assembly 30 and the bottom of the shell 10. The power supply assembly 30 is electrically connected to the motor assembly 20 for supplying power to the motor assembly 20. The power supply assembly 30 may include a battery, which may be a dry cell battery or a storage battery. This application does not specifically limit the type of battery.

[0039] Specifically, the brush handle also includes a first soft shock absorber 40 and a display unit 52. The first soft shock absorber 40 is disposed on the periphery of the housing 10 and is connected to the housing 10. The hardness of the first soft shock absorber 40 is less than that of the housing 10. The first soft shock absorber 40 can be made of a soft material such as soft plastic or silicone and has a cushioning and shock-absorbing function. Of course, the first soft shock absorber 40 can also be made of other soft materials. This application does not impose specific restrictions on the material of the first soft shock absorber 40. The display unit 52 is connected to the housing 10 and is located on the side of the first soft shock absorber 40 close to the head 11. The display unit 52 can be a component capable of displaying images, such as a display screen or a display window.

[0040] It is understood that in the present application, when a user grips the handle of an electric toothbrush to clean their oral cavity, they grip the area of the housing 10 where the first soft shock absorber 40 is located. The first soft shock absorber 40 contacts the user's palm, and the vibration generated by the motor assembly 20 inside the housing 10 during operation is transmitted to the user's palm via the housing 10 and the first soft shock absorber 40 in sequence. The first soft shock absorber 40 can effectively buffer and reduce the vibration transmitted to the user's palm by the motor assembly 20, thereby enhancing user comfort. This is particularly suitable for users such as children who are more sensitive to vibration. In addition, the display portion 52 is located on the side of the first soft shock absorber 40 close to the head 11, so that when the user grips the handle and uses the brush, the display portion 52 is located above the first soft shock absorber 40, preventing the display portion 52 from being blocked by the user's grip on the first soft shock absorber 40. At the same time, the user can more conveniently observe the image displayed on the display portion 52.

[0041] Continue to see Figure 4 and Figure 5 As shown, in some embodiments of the present application, the brush handle also includes a display portion 52, which is connected to the shell 10, and the distance between the display portion 52 and the head 11 is smaller than the distance between the display portion 52 and the bottom 12, so that the display portion 52 can be located in the upper middle part of the shell 10, so that the user can observe the picture displayed on the display portion 52 when using the electric toothbrush.

[0042] In some embodiments, the first soft shock absorber 40 may extend along the outer circumference of the housing 10. The first soft shock absorber 40 may extend along the outer circumference of the housing 10 by L / 4, L / 3, L / 2, 1, or other number of turns. It should be noted that when the first soft shock absorber 40 extends along the outer circumference of the housing 10 by L / 4, it means that the length of the first soft shock absorber 40 along the circumference of the housing 10 is one-quarter of the circumference of the outer circumferential surface of the housing 10; when the first soft shock absorber 40 extends along the outer circumference of the housing 10 by L / 3, it means that the length of the first soft shock absorber 40 along the circumference of the housing 10 is one-third of the circumference of the outer circumferential surface of the housing 10, and so on.

[0043] Continue to refer to Figure 1 to Figure 3 As shown, in some embodiments of the present application, a first soft shock absorber 40 is disposed around the outer circumference of the housing 10. It is understood that the first soft shock absorber 40 is an annular structure that is sleeved on the housing 10. The first soft shock absorber 40 can be a circular ring structure or a square ring structure. The first soft shock absorber 40 is disposed around the outer circumference of the housing 10 in at least one circle, thereby increasing the contact area between the user's palm and the first soft shock absorber 40 when the user grips the housing 10, thereby further reducing the vibration transmitted to the user's palm by the motor assembly 20 and enhancing user comfort. In addition, the connection between the first soft shock absorber 40 and the housing 10 can be made tighter, preventing the first soft shock absorber 40 from detaching from the housing 10.

[0044] In some embodiments, the length of the shell 10 is L, the distance between the first soft shock absorber 40 and the head 11 along the length direction of the shell 10 is L1, and the distance between the first soft shock absorber 40 and the bottom 12 along the length direction of the shell 10 is L2, 0≤L1≤L / 3, 0≤L2≤L / 3, so that the distances between the first soft shock absorber 40 and the bottom 12 and the head 11 are moderate, so that the first soft shock absorber 40 can be set in the middle area of the shell 10, and the length of the first soft shock absorber 40 along the length direction of the shell 10 can be greater than L / 3, so that the first soft shock absorber 40 has sufficient length to meet the shock absorption requirements, so that the user can contact the first soft shock absorber 40 when holding the shell 10. Among them, L1 can be 0, 0.1L, 0.2L, 0.3L or other multiples of L, and L2 can be 0, 0.1L, 0.2L, 0.3L or other multiples of L. The specific values of L, L1 and L2 can be selected according to actual needs, and this application will not go into details.

[0045] like Figure 4 As shown, in some embodiments of the present application, the projection of the first soft shock absorber 40 on the outer circumferential surface of the housing 10 at least partially overlaps with the projection of the motor assembly 20 on the outer circumferential surface of the housing 10. In the radial direction of the housing 10, the first soft shock absorber 40 has an overlapping portion that overlaps with the motor assembly 20. It can be understood that, generally speaking, the portion of the housing 10 that is opposite to the motor assembly 20 is closer to the motor assembly 20, so that the vibration of the portion of the housing 10 that is opposite to the motor assembly 20 is stronger than the vibration of other portions of the housing 10. The overlapping portion of the first soft shock absorber 40 is disposed at the portion of the housing 10 that is opposite to the motor assembly 20, so that the first soft shock absorber 40 can directly contact the portion of the housing 10 that vibrates more strongly, thereby achieving a better buffering and shock absorbing effect.

[0046] Furthermore, the portion of the housing 10 surrounding the motor assembly 20 is a surrounding portion, and at least a portion of the first soft shock absorber 40 is disposed around the outer periphery of the surrounding portion, so that at least a portion of the first soft shock absorber 40 is disposed around the motor assembly 20. That is, the overlapping portion of the first soft shock absorber 40 and the motor assembly 20 is disposed around the motor assembly 20, which can increase the contact area between the first soft shock absorber 40 and the portion of the housing 10 that vibrates more strongly, thereby achieving a better cushioning and shock-absorbing effect.

[0047] like Figure 4 and Figure 5 As shown, in some embodiments of the present application, the shell 10 includes a grip portion 13 located between the head 11 and the bottom 12, and the tube radial direction of the grip portion 13 gradually increases in the direction close to the head 11, and / or, the tube radial direction of the grip portion 13 gradually increases in the direction close to the bottom 12, so that the shell 10 as a whole can have a structure that is narrow in the middle and thick at both ends. The grip portion 13 is used for the user to hold, making it more convenient and more stable for the user to hold the shell 10, preventing the brush handle from slipping during use.

[0048] Furthermore, the first soft shock absorber 40 is arranged on the gripping portion 13, which can make the first soft shock absorber 40 installed more firmly and prevent the first soft shock absorber 40 from detaching from the shell 10, while also making it easier for the user to hold the first soft shock absorber 40 when holding the shell 10.

[0049] In some embodiments of the present application, the handle further includes a button 51 disposed on the housing 10. The user can adjust the power on and off, operating mode, gear position, etc. of the electric toothbrush by pressing the button 51. The first soft shock-absorbing member 40 covers the button 51, allowing the user to press the button 51 by pressing the first soft shock-absorbing member 40. The first soft shock-absorbing member 40 is made of a relatively soft material, which can reduce the user's discomfort when pressing the button 51, thereby improving the user's operating experience.

[0050] Continue to see Figure 4 and Figure 5As shown, in some embodiments, the first soft shock absorber 40 includes a first part 41 and a second part 42. In the length direction of the shell 10, the first part 41 is positioned opposite to the display part 52, and the second part 42 is staggered with the display part 52. The length of the first part 41 along the length direction of the shell 10 is greater than the length of the second part 42 along the length direction of the shell 10. It can be understood that the length of the first part 41 corresponding to the display part 52 is greater than the length of the second part 42 which is offset from the display part 52. When holding the brush handle for brushing, for example, to facilitate brushing, the palm of the hand will usually contact the side of the shell 10 facing the face, and the fingers will contact the side of the shell 10 facing away from the face. At the same time, for the convenience of observation, the display part 52 is usually set on the side of the shell 10 facing the face. The first part 41 and the display part 52 are located on the same side of the shell 10, so that the first part 41 is also located on the side of the shell 10 facing the face, so that the palm of the hand is easier to contact with the first part 41. Since the length of the first part 41 is relatively large, it can have more contact area with the palm of the hand, which can further reduce the vibration transmitted to the user's palm by the motor assembly 20, thereby enhancing the user's comfort. At the same time, the length of the second part 42 is relatively small, which can reduce the material usage of the length of the first soft shock absorber 40 and reduce the cost of the first soft shock absorber 40.

[0051] Continue to see Figure 3 and Figure 4 As shown, in some embodiments of the present application, the brush handle further includes a second soft shock-absorbing member 60, which is disposed on the outer periphery of the housing 10 and connected to the housing 10, and the display unit 52 is disposed on the second soft shock-absorbing member 60. It is understood that the hardness of the second soft shock-absorbing member 60 is less than that of the housing 10. The second soft shock-absorbing member 60 can be made of a soft material such as soft plastic or silicone, and has a cushioning and shock-absorbing function. Of course, the second soft shock-absorbing member 60 can also be made of other soft materials. This application does not impose any specific restrictions on the material of the second soft shock-absorbing member 60. The second soft shock-absorbing member 60 can provide protection for the display unit 52, reduce vibrations to the display unit 52, and prevent damage to the display unit 52 due to vibration.

[0052] In some embodiments, a groove 61 is provided on the outer surface of the second soft shock-absorbing component 60, and the display part 52 is located in the groove 61. The groove 61 can be used to provide a storage space for the display part 52, thereby reducing the overall volume of the brush handle, making the brush handle easier to store and carry. At the same time, the surrounding side of the display part 52 can be covered, providing better buffering and shock-absorbing protection for the display part 52.

[0053] In some embodiments, the distance between the outer side of the second soft shock absorber 60 and the bottom of the groove 61 along the groove depth direction of the groove 61 is d1, and the distance between the light-emitting surface 521 of the display portion 52 and the bottom of the groove 61 along the groove depth direction of the groove 61 is d2, d2 < d1, so that the light-emitting surface 521 of the display portion 52 can be hidden within the groove 61, preventing liquid from splashing onto the light-emitting surface 521 of the display portion 52 during brushing and affecting the display effect. It also prevents the light-emitting surface 521 from colliding with other objects when the brush handle falls, causing damage to the display portion 52. The specific values of d1 and d2 can be selected according to actual needs.

[0054] Furthermore, d3 = d1 - d2, and 0.1 mm ≤ d3 ≤ 1.5 mm, so that the distance between the light-emitting surface 521 of the display unit 52 and the outer side of the second soft shock-absorbing member 60 is moderate. While effectively protecting the light-emitting surface 521 of the display unit 52, the light-emitting surface 521 of the display unit 52 is prevented from being too deeply hidden, making it difficult for the user to observe the display screen of the display unit 52. d3 can be 0.1 mm, 0.5 mm, 1 mm, 1.5 mm, or other values.

[0055] In some embodiments, a side opening 14 is provided on the outer periphery of the housing 10, and a second soft shock absorber 60 seals the side opening 14. After removing the second soft shock absorber 60, the user can inspect and maintain the components within the housing 10 through the side opening 14. The second soft shock absorber 60 ensures the sealing of the side opening 14, preventing liquid from entering the housing 10 through the side opening 14 and damaging the electronic components within the housing 10. The second soft shock absorber 60 can be formed on the housing 10 by secondary injection molding or dispensing.

[0056] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the bottom 12 is provided with a bottom opening 15, and the brush handle further includes a third soft shock absorber 70. The third soft shock absorber 70 is disposed on the bottom 12 and seals the bottom opening 15. It is understood that the hardness of the third soft shock absorber 70 is less than that of the housing 10. The third soft shock absorber 70 can be made of a soft material such as soft plastic or silicone. Of course, the third soft shock absorber 70 can also be made of other soft materials. This application does not impose any specific restrictions on the material of the third soft shock absorber 70. The third soft shock absorber 70 ensures the sealing of the bottom opening 15, preventing liquid from entering the interior of the housing 10 through the bottom opening 15 and damaging the electronic components within the housing 10. In addition, when the brush handle is placed upright on a table or other surface, the third soft shock absorber 70 contacts the surface, reducing the impact of table vibration on the brush handle. Furthermore, the third soft shock absorber 70 is deformed by compression, increasing the contact area with the surface and the stability of the connection, making the brush handle more secure.

[0057] In some embodiments of the present application, an anti-slip structure is provided on the outer periphery of the shell 10, and the anti-slip structure is arranged back to back with the display part 52. When the user holds the shell 10, the palm of the user can contact the anti-slip structure, thereby increasing the friction between the palm and the shell 10 and preventing the brush handle from falling.

[0058] In the second aspect, based on the above-mentioned brush handle, the present application also provides an electric toothbrush, such as Figure 6 As shown, the electric toothbrush includes a brush head 80 and a brush handle as in any of the above embodiments. The brush head 80 is mounted on the brush handle and is in transmission connection with the motor assembly 20. The motor assembly 20 can drive the brush head 80 to vibrate, so as to perform oral cleaning using the brush head 80. Specifically, the brush head 80 can be detachably connected to the output shaft 21 of the motor assembly 20.

[0059] In some embodiments, the electric toothbrush further includes a brush head cover, which is a detachable cover provided on the brush head 80 for protecting the brush head 80. When the electric toothbrush is not in use, the brush head cover can be used to cover the brush head 80 to prevent dirt from contaminating the brush head 80. The brush head cover can be in a cube, sphere, or other shape.

[0060] In some embodiments, the distance between the top of the bristles of the brush head 80 and the bottom of the groove 61 along the groove depth direction of the groove 61 is less than d1, so that when the brush handle is as shown in FIG. Figure 6 When placed flat as shown, the top of the second soft shock-absorbing member 60 is higher than the top of the bristles of the brush head 80, preventing liquid from splashing onto the light-emitting surface 521 of the display portion 52 during brushing and affecting the display effect.

[0061] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
