Description

Technical Field

[0001] The present disclosure relates to the technical field of oral cleaning, and in particular to a handle of an oral cleaning appliance; the present disclosure also relates to an oral cleaning appliance. Background Art

[0002] As living standards improve, people's awareness of oral care is gradually increasing, and oral cleaning tools are becoming more diverse on the market. Take electric toothbrushes as an example. The drive motor in the handle drives the toothbrush head to swing or vibrate. When brushing, the user holds the handle and presses the toothbrush head against the teeth to clean them.

[0003] In the prior art, the handle of an oral cleaning appliance usually fixes the bracket inside the shell and installs the drive motor on the bracket. During the cleaning process, the vibration force of the drive motor will be transmitted to the bracket, causing the bracket to vibrate and apply force to the shell, resulting in a strong vibration sensation in the handle and a poor user experience. In addition, the various components fixed to the bracket are easily damaged by vibration. How to improve the fixing method of the bracket to reduce the vibration of the bracket and reduce the vibration sensation of the handle is a technical problem that needs to be solved urgently in this field.

Detailed Description of the Embodiment

[0043] Now, various exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangement of the components and steps set forth in these embodiments, the numerical expressions and values do not limit the scope of the present disclosure.

[0044] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation to the present disclosure and its application or use.

[0045] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be regarded as part of the specification.

[0046] It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof in subsequent figures is not necessary.

[0047] In this document, terms such as "upper", "lower", "front", "rear", "left", "right", etc. are only used to represent the relative positional relationship between relevant parts, rather than defining the absolute positions of these relevant parts.

[0048] In this document, terms such as "first", "second", etc. are only used to distinguish between each other, rather than indicating importance, order, and the prerequisite for each other's existence, etc.

[0049] In this document, terms such as "equal", "same", etc. are not strict mathematical and / or geometric limitations, but also include allowable errors that can be understood by those skilled in the art and are permitted in manufacturing or use, etc.

[0050] Referring to Figure 1 and Figure 2 , the present disclosure provides an oral cleaning appliance handle 100, which can be used for oral cleaning appliances such as electric toothbrushes, flushing integrated machines, etc. The oral cleaning appliance handle 100 includes: a housing 1, a drive assembly 2, and a bracket 3. Among them, the housing 1 has a receiving cavity inside, and both the drive assembly 2 and the bracket 3 can be arranged in the receiving cavity. The housing 1 is configured to be suitable for gripping, and a user can hold the housing 1 by hand to operate the oral cleaning appliance.

[0051] Referring to Figure 6 , the housing 1 extends along a first axis, and the opposite ends of the first axis are denoted as the first end and the second end. Referring to Figure 6 the view direction, the upper end is the first end, and the lower end is the second end. The housing 1 includes a first opening 11 provided at the first end and a second opening 12 provided at the second end. The first opening 11 and the second opening 12 are respectively communicated with the upper and lower ends of the receiving cavity.

[0052] Referring to Figure 2 and Figure 3 , the drive assembly 2 is arranged in the receiving cavity. The drive assembly 2 includes a drive motor 21, and the drive motor 21 has an output shaft 211 extending along the first axis direction. The output shaft 211 is configured to pass through the housing 1 through the first opening 11. The output shaft 211 can be used to connect the brush head 200 of the oral cleaning appliance, so that the drive motor 21 can drive the brush head 200 to swing, so as to enable the oral cleaning appliance to have a good cleaning effect.

[0053] The bracket 3 is used to mount the drive assembly 2. The bracket 3 is mounted into the accommodation cavity along the first axis direction through the second opening 12. When the drive motor 21 is working, it will vibrate, and the vibration will be transmitted to the bracket 3. The vibration of the bracket 3 will be further transmitted to the housing 1, making the vibration feeling of the oral cleaning appliance handle 100 strong.

[0054] In an embodiment of the present disclosure, as Figure 2 shown, the drive assembly 2 includes a flexible sleeve 22, and the flexible sleeve 22 is configured to at least partially wrap the drive motor 21. The flexible sleeve 22 can be made of soft and elastic materials such as silica gel and rubber. A flexible sleeve 22 is provided between the drive motor 21 and the bracket 3 for buffering, so as to reduce the transmission of vibration to a certain extent. However, the flexible sleeve 22 cannot completely isolate the vibration, and the bracket 3 will still be driven to vibrate by the drive motor 21 and transmit the vibration to the housing 1.

[0055] To solve the problem of strong vibration feeling of the oral cleaning appliance handle 100, the structure of the bracket 3 is designed in the present disclosure so that it is elastically connected in the housing 1. Specifically, at least one fixing member and a plurality of elastic members spaced apart in the circumferential direction of the first axis are provided on the bracket 3. Among them, the bracket 3 is axially fixed in the housing 1 through the fixing member. Under the action of the fixing member, the bracket 3 will not move in the axial direction.

[0056] In an embodiment of the present disclosure, referring to Figures 5 to 7 , the fixing member is provided at the second end of the bracket 3, and a mating portion adapted to the fixing member is provided at a position on the inner wall of the housing 1 adjacent to the second opening 12. Specifically, as Figure 5 shown, the fixing member is configured as a boss 31 that expands outward in the radial direction of the first axis, and the mating portion is configured as a groove 13 that matches the shape of the boss 31. At least two bosses 31 are provided, and at least two bosses 31 are spaced apart in the circumferential direction of the bracket 3; at least two grooves 13 are provided, and at least two grooves 13 are respectively provided corresponding to the bosses 31. The boss 31 is configured to be elastically embedded in the groove 13.

[0057] When installing the bracket 3 into the accommodation cavity, the bracket 3 can be pushed into the accommodation cavity from the second opening 12. The bracket 3 can be made of plastic material and has a certain elasticity. When at least two bosses 31 enter the accommodation cavity through the second opening 12, they will be compressed and deformed inward by the inner wall of the housing 1 until the bracket 3 moves along the first axis direction to a position where the bosses 31 correspond to the grooves 13, and then at least two bosses 31 will reset under the action of elastic force and respectively snap into their corresponding grooves 13.

[0058] In a specific embodiment of the present disclosure, continue to refer to Figures 5 to 7, in the first axis direction, the boss 31 includes a first side surface 311 that abuts against the groove 13, and the groove 13 includes a second side surface 131 that abuts against the first side surface 311. The first side surface 311 is located on the side of the second side surface 131 away from the second opening 12. The second side surface 131 is configured to limit the degree of freedom of movement of the bracket 3 towards the second opening 12. Refer to Figure 5 the view direction, the first side surface 311 is the lower end surface of the boss 31, and the first side surface 311 is perpendicular to the first axis. When the boss 31 is installed in place, the second side surface 131 of the groove 13 abuts against the first side surface 311 of the boss 31. The installed bracket 3 will not move towards the second opening 12 under the limiting action of the second side surface 131, thereby realizing the axial fixation of the bracket 3, improving the stability and reliability of the clamping structure between the bracket 3 and the housing 1, and achieving an effective anti-disconnection effect.

[0059] In a specific embodiment of the present disclosure, in the first axial radial direction, the boss 31 includes a third side surface 312 that abuts against the groove 13, and the groove 13 includes a fourth side surface 132 that abuts against the third side surface 312; the fourth side surface 132 is configured to form a radial support for the boss 31. As Figure 7 shown, the third side surface 312 is the outer wall of the boss 31, as Figure 6 shown, the fourth side surface 132 is the inner wall of the groove 13. After the bracket 3 is installed in place and the boss 31 snaps into the groove 13, the third side surface 312 can fit against the fourth side surface 132, thereby playing a supporting role in the radial direction. At least a part of the fourth side surface 132 can be configured as an inclined surface, and other positions of the bracket 3 will not be stuck by the groove 13 when passing through the groove 13, but can continue to move under the guiding action of the fourth side surface 132, thereby reducing the installation difficulty of the bracket 3.

[0060] As described above, a plurality of elastic members are provided on the bracket 3 and are spaced apart in the circumferential direction of the first axis. Specifically, the elastic members are provided on the outer wall of the bracket 3 and are in elastic contact with the inner wall of the housing 1. The bracket 3 can move relative to the housing 1 at least in the radial direction through the plurality of elastic members. Refer to Figure 4 , in a specific embodiment of the present disclosure, the bracket 3 includes a press-fitting surface that is in interference fit with the inner wall of the housing 1. The press-fitting surface extends along the first axis and is in press-fitting cooperation with the inner wall surface of the housing 1. The bracket 3 includes positioning side plates 34 located on two opposite sides and extending along the first axis, and the elastic members are provided on the side walls of the positioning side plates 34 that cooperate with the inner wall of the housing 1.

[0061] In this embodiment, an interference fit is formed between the bracket 3 and the housing 1, which can facilitate the installation and fixation between the bracket 3 and the housing 1. The positioning side plate 34 of the bracket 3 can facilitate the formation of an interference fit between the bracket 3 and the housing 1. In addition, it can also facilitate the formation of a guide groove on the inner wall of the housing 1 to cooperate with the positioning side plate 34 to limit the circumferential position of the bracket 3 in the housing 1, ensuring the accuracy and reliability of the installation structure of the bracket 3 in the housing 1.

[0062] In a specific embodiment of the present disclosure, as Figure 4 shown, the elastic member includes an elastic arm 321 and elastic protrusions 322 provided on the elastic arm 321. The number of elastic protrusions 322 on each positioning side plate 34 is at least two, and at least two elastic protrusions 322 are arranged at intervals in the direction of the first axis, so as to achieve multi-point elastic support in the first axial direction. By providing elastic protrusions 322 protruding towards the inner wall of the housing 1 on the positioning side plate 34, when the bracket 3 is inserted into the housing 1, the elastic action of the elastic protrusions 322 can be utilized to achieve self-adaptive adjustment of the tightness, which can more effectively ensure the stability of the cooperation structure between the bracket 3 and the housing 1. The elastic protrusions 322 can be convex points, arc protrusions or strip protrusions, or other protrusion structures.

[0063] Furthermore, through holes 341 are formed in the positioning side plate 34 in a direction perpendicular to the first axis. The elastic arm 321 is configured to be located on the side of the through hole 341 close to the housing 1 and is configured to be deformed into the through hole 341 under the action of an external force. In this embodiment, by forming the through holes 341 in the positioning side plate 34, a deformation space can be provided for the deformation of the elastic protrusions 322, reducing the extrusion force applied by the elastic protrusions 322 to the housing 1 during the installation process, reducing the installation difficulty of the bracket 3 in the housing 1, and at the same time not affecting the elastic abutting effect of the elastic protrusions 322 on the inner wall of the housing 1, ensuring the installation and positioning effect of the bracket 3 and the housing 1.

[0064] The present disclosure realizes elastically setting the bracket 3 in the housing 1 by providing a fixing member and an elastic member on the bracket 3. Under the action of the fixing member, the bracket 3 will not move in the axial direction; under the action of the elastic member, the bracket 3 can move relative to the housing 1 in the radial direction. Under the action of the vibration of the drive motor 21, the bracket 3 and the housing 1 can be buffered through the elastic member, so that the vibration of the bracket 3 is weakened, thereby reducing the vibration feeling of the oral cleaning appliance handle 100 and improving the user experience.

[0065] In an embodiment of the present disclosure, as Figure 2 shown, the oral cleaning appliance handle 100 further includes a tail cap 4, as Figure 3As shown, the end cap 4 is installed at a position in the accommodation cavity adjacent to the second opening 12. The end cap 4 can block the second opening 12 of the housing 1. As previously mentioned, the output shaft 211 of the drive motor 21 blocks the first opening 11 of the housing 1, thereby making the accommodation cavity airtight.

[0066] Specifically, a first connecting member is provided at the second end of the bracket 3, and a second connecting member is provided on the end cap 4. The second connecting member is configured to be connected to the first connecting member to connect the end cap 4 to the bracket 3. Refer to Figure 7 and Figure 8 , the first connecting member is configured as a buckle 33 that protrudes outward in the radial direction of the first axis, and the second connecting member is configured as a bayonet 411 adapted to the buckle 33. The buckle 33 is configured to be elastically inserted into the bayonet 411 to fix the end cap 4 to the bracket 3. When assembling the handle 100 of the oral cleaning appliance, the end cap 4 can be first connected to the second end of the bracket 3 through the snap connection structure, and then the bracket 3 can be installed into the housing 1 through the second opening 12, so as to install the end cap 4 at a position in the accommodation cavity adjacent to the second opening 12.

[0067] In an embodiment of the present disclosure, there are at least two buckles 33, and the at least two buckles 33 are spaced apart along the circumferential direction of the bracket 3. There are at least two bayonets 411, and the at least two bayonets 411 are respectively arranged corresponding to the buckles 33. In this embodiment, as Figure 7 shown, there can be three buckles 33. Correspondingly, as Figure 8 shown, there can also be three bayonets 411. As described above, there are two fixing members (i.e., bosses 31), and the two fixing members are evenly spaced along the circumferential direction of the bracket 3 at the second end of the bracket 3. In the circumferential direction, one or two buckles 33 are located between the two fixing members.

[0068] The two bosses 31 for connecting the housing 1 and the three buckles 33 for connecting the end cap 4 are both provided at the second end of the bracket 3 and are distributed substantially evenly along the circumferential direction. Specifically, taking one of the bosses 31 as the starting point, the distribution manner in the circumferential direction is: the starting boss 31, two buckles 33, the other boss 31, one buckle 33, and finally back to the starting boss 31. The structures for snap connection on the bracket 3 are all concentrated at a position adjacent to the second opening 12. The present disclosure provides a reasonable layout method. The two bosses 31 are substantially symmetrically arranged along the first axis, and the three buckles 33 are substantially evenly distributed in the circumferential direction, so that the bracket 3 can be stably and reliably snap-connected to the housing 1 and the end cap 4, and the two sets of snap connection structures will not affect each other.

[0069] In an embodiment of the present disclosure, refer to Figure 8 and Figure 9, at the first end of the end cap 4, there are provided at least two mounting walls 412 extending in the direction of the first axis. The at least two mounting walls 412 are spaced apart circumferentially around the end cap 4, and each mounting wall 412 is provided with a bayonet 411. As described above, when there are three bayonets 411, there are also three mounting walls 412. The mounting walls 412 extend towards the first end direction, so that the bayonets 411 located on the mounting walls 412 are at a position on the end cap 4 adjacent to the first end, thus being easy to be snap-connected with the buckle 33 located at the second end of the bracket 3.

[0070] As Figure 8 shown, a positioning groove 413 adapted to the buckle 33 is provided on the mounting wall 412. The positioning groove 413 extends in the direction of the first axis. The positioning groove 413 can be provided on the inner side of the mounting wall 412, and the bayonet 411 is located in the positioning groove 413. During the installation process, the buckle 33 is configured to slide along the positioning groove 413 and be embedded into the bayonet 411. The three buckles 33 can respectively correspond to the three positioning grooves 413. The three buckles 33 can be deformed under the extrusion of the mounting wall 412, so as to enter the three positioning grooves 413 and slide along the positioning grooves 413 towards the second end direction. When the buckle 33 moves to the position corresponding to the bayonet 411, the buckle 33 can be snap-connected into the bayonet 411 under the action of elastic force, thus enabling the bracket 3 and the end cap 4 to form a stable connection.

[0071] In an embodiment of the present disclosure, referring to Figures 8 to 10 , the end cap 4 includes a main body portion 41 provided with a second connecting member, and a waterproof cover 42 mounted on the main body portion 41. The main body portion 41 is located at the first end of the end cap 4, so as to be used for connecting with the bracket 3; the waterproof cover 42 is located at the second end of the end cap 4, and is snap-connected and sealed with the inner wall of the housing 1, so as to be able to cover the main body portion 41.

[0072] Specifically, as Figure 8 shown, a charging port 414 for connecting with an external circuit is provided on the second end of the main body portion 41. As Figure 2 shown, a charging member 44 can be fixedly connected in the charging port 414. The charging member 44 can specifically be, for example, a plug-in port of a Type-C board. When charging is required, the user can insert the charging head through the charging port 414 into the charging member 44 located inside, so as to connect with the external circuit.
