Description

Technical Field

[0001] This invention relates to cleaning and care appliances such as electric toothbrushes, and more particularly to cleaning and care appliances, such as electric toothbrushes, having a linkage mechanism that converts the rotational motion of a drive unit into the reciprocating rotation of a drive shaft. Background Technology

[0002] Currently, various handheld electric cleaning and personal care products are available on the market, such as electric toothbrushes. An electric toothbrush has a handle and a brush head attached to a drive shaft that extends from the handle. A rotary motor is housed inside the handle. The driving force provided by the rotary motor is output through its output shaft and converted into the reciprocating rotation of the drive shaft via a planar four-bar linkage, thereby causing the brush head to oscillate back and forth.

[0003] In existing electric toothbrushes that use a motor as a drive device, the longitudinal axis of the rotary motor and the longitudinal axis of the drive shaft directly attached to the brush head are parallel and offset from each other, with an offset distance usually greater than 5mm. In this case, in order to reduce the size of the product, the brush head of the electric toothbrush is eccentrically arranged relative to the central longitudinal axis of the handle.

[0004] However, due to the limitations of the existing planar four-bar linkage structure and the mounting structure of the drive shaft, the overall shape of existing motor-driven electric toothbrushes is relatively large, and the appearance design is limited by the offset of the longitudinal axis of the brush head and handle center.

[0005] Therefore, it is still necessary to improve existing electric cleaning and care products with motor drives, reducing their size while enhancing their aesthetic design. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the present invention provides a cleaning and care device, comprising: a housing, the housing having an interior forming a cavity; a motor, the motor including an output shaft having a first axis, the output shaft rotating, the motor being disposed in the cavity, and a drive wheel being provided on the output shaft; a drive shaft having a second axis and extending out of the cavity; and a linkage mechanism connected to the drive wheel of the output shaft and the drive shaft respectively and configured to convert the rotational motion of the output shaft about the first axis into the reciprocating rotation of the drive shaft about the second axis; wherein, the cleaning and care device includes a frame disposed adjacent to the motor within the housing, the frame having a frame bottom wall, a first boss and a second boss protruding from the frame bottom wall, the drive shaft being received in a first boss cavity formed by the first boss, and the second boss having a hole in which the drive shaft is received for the reciprocating rotation, the second boss being stacked above the first boss such that the hole is located above the first boss cavity.

[0007] According to another aspect of the invention, the second boss is stacked above the first boss, such that the first axis of the output shaft is substantially aligned with the second axis of the drive shaft. That is, the longitudinal axes of the output shaft and the drive shaft are on a straight line or have a parallel offset distance of less than 1 mm, and the distal end of the drive shaft is located directly above the output shaft.

[0008] This positional relationship between the drive shaft and the output shaft reduces the size of the handle and avoids the brush head being offset relative to the handle, making the shape design more flexible.

[0009] By using a frame with two stacked bosses, both the output shaft and the drive shaft can be kept in the same frame while the axes of the motor output shaft and the drive shaft are substantially aligned.

[0010] According to another aspect of the invention, a boss hole bottom is provided between the first boss and the second boss, the boss hole bottom abutting against the end of the drive shaft, and the boss hole bottom is integrally formed with at least one of the first boss and the second boss.

[0011] According to another aspect of the invention, the output shaft of the motor is provided with a driving wheel, the driving wheel being at least partially accommodated within the first boss cavity, and the linkage mechanism further includes: a driven wheel, the driven wheel meshing with the driving wheel gear; a driven wheel eccentric rod, the driven wheel eccentric rod being connected to the driven wheel, and the central axis of the driven wheel eccentric rod being eccentrically arranged relative to the rotation axis of the driven wheel; a connecting rod, one end of the connecting rod being connected to the driven wheel eccentric rod; a drive shaft eccentric rod, the drive shaft eccentric rod being connected to the other end of the connecting rod; and a drive shaft connecting rod, one end of the drive shaft connecting rod being connected to the drive shaft eccentric rod, and the other end of the drive shaft connecting rod being fixed to the drive shaft.

[0012] According to another aspect of the invention, the first boss has a first boss wall circumferentially surrounding the driving wheel, the first boss wall having a notch at which the driven wheel and the driving wheel mesh.

[0013] According to another aspect of the invention, the other end of the drive shaft connecting rod is fixed to the drive shaft above the second boss.

[0014] According to another aspect of the invention, the frame further includes an outer frame wall extending from the bottom wall of the frame and integrally formed with and surrounding the linkage mechanism, wherein the bottom wall of the frame has a first opening between the first boss and the outer wall, the first opening accommodating one end of the driven wheel eccentric rod.

[0015] According to another aspect of the invention, the second boss is formed separately from the first boss, and the second boss is snapped onto the first boss.

[0016] According to another aspect of the invention, the bottom wall of the frame forms a boss bottom hole on the side of the first boss near the motor, and the output shaft of the motor extends into the first boss cavity through the boss bottom hole.

[0017] According to a preferred embodiment of the invention, the frame provides a compact arrangement by mounting the linkage mechanism and the drive shaft using two overlapping bosses. Particularly advantageously, in this invention, the longitudinal axis of the electric toothbrush head and the longitudinal axis of the handle can be substantially aligned, and the drive shaft is kept substantially aligned with the motor's output shaft using the same frame, resulting in accurate positioning and convenient installation.

[0062] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0063] The following description uses an electric toothbrush 100 as a typical example of a personal hygiene product, and describes exemplary embodiments of the invention in more detail with reference to the accompanying drawings. Although the following explanation uses only an electric toothbrush 100 as an example, the invention is not limited thereto. The invention can also be applied to personal hygiene products such as electric shavers, electric facial cleansers, and electric showers that can provide cleaning action through a drive mechanism.

[0064] For clarity, this specification uses terms describing spatial relative positions, such as "proximal / proximal" and "distal / distal," to simply describe the relationship between one element or feature and another element (one or more) or feature (one or more) as shown in the figure. "Proximal / proximal" refers to the end or side near the point where the cleaning force is applied when the cleaning and care product is used; "distal / distal" refers to the end or side away from the point where the cleaning force is applied when the cleaning and care product is used.

[0065] Furthermore, the term “and / or” as used in this application includes any one and all combinations of the one or more associated terms listed.

[0066] Although the terms "first" and similar terms are used in this specification to describe multiple elements or components, these elements or components should not be limited by these terms. These terms are used only to distinguish one element or component from another and do not imply "order." Therefore, changing the ordinal numbers of the elements or components discussed below does not exceed the concept and scope of this invention.

[0067] Figure 1 A perspective view of a cleaning and care appliance according to a preferred embodiment of the present invention is shown, the cleaning and care appliance being an electric toothbrush 100.

[0068] The electric toothbrush 100 mainly includes a handle portion 1 and a brush head 2 detachably mounted on the handle portion 1. The handle portion 1 includes a handle housing 6 and various functional components mounted in the handle housing 6. The brush head 2 is provided with cleaning elements 4 such as bristles. A switch portion 3 is provided in the middle of the handle housing 6, slightly near the proximal end. When the user presses the switch portion 3, the various functional components inside the electric toothbrush 100 can be turned on, causing the brush head 2 to reciprocate.

[0069] Figure 2 The internal structure of the electric toothbrush 100 according to a preferred embodiment of the present invention is further illustrated. For example... Figure 2 As shown, along the longitudinal direction of the electric toothbrush 100 from distal to proximal end, the electric toothbrush 100 includes a battery 5, a circuit board 8, a motor 10, a linkage mechanism 7, and a drive shaft 11 disposed within a chamber formed in the handle housing 6. Furthermore, as... Figure 2 As shown, the handle housing 6 contains a frame 20 that houses and holds the linkage mechanism 7 and the drive shaft 11, and a frame cover 26 that is assembled with the frame 20 on the proximal side of the frame 20.

[0070] In a preferred embodiment, the battery 5 is disposed at the distal end of the chamber of the handle portion 1 to provide power to the motor 10 of the electric toothbrush 100. A circuit board 8 is disposed between the battery 5 and the motor 10, and is equipped with switches and related control devices. The circuit board 8 is located at the distal end of the motor 10, while the output shaft of the motor 10 extends proximally toward the linkage mechanism 7. When the motor 10 is actuated, the output shaft is capable of rotational motion about its longitudinal axis L2 (first axis). The linkage mechanism 7 is configured to connect the drive wheel 16 and the drive shaft 11 to the output shaft of the motor 10, respectively, for converting the rotational motion of the output shaft about its longitudinal axis L1 (second axis) into reciprocating rotation of the drive shaft 11 about its longitudinal axis L1 (second axis). At the proximity of the handle housing 6 of the electric toothbrush 100, the drive shaft 11 connected to the linkage mechanism 7 partially extends out of the chamber formed by the handle housing 6 of the handle to connect the brush head 2.

[0071] Figure 3 To illustrate a plan view of the linkage mechanism 7 according to a preferred embodiment of the present invention, Figure 4 A perspective view of the motor 10 and linkage mechanism 7 according to a preferred embodiment of the present invention is shown. Figure 3 and Figure 4 As shown, the linkage mechanism 7 includes a driven wheel 15, a driven wheel eccentric rod 17, a connecting rod 14, a drive shaft eccentric rod 13, and a drive shaft connecting rod 12. These components constitute a four-bar linkage.

[0072] Specifically, in a preferred embodiment, the driving gear 16 is a cylindrical gear mounted on the output shaft of the motor 10. The rotation axis of the driving gear 16 is aligned with the longitudinal axis L2 of the output shaft, and the rotation of the output shaft of the motor 10 drives the driving gear 16 to rotate. The driven gear 15 is also a cylindrical gear, meshing with the driving gear 16. The rotation axis of the driven gear 15 is parallel to but separated from the rotation axis of the driving gear 16 by a distance. The driven gear eccentric rod 17 in the linkage mechanism 7 is arranged basically along the longitudinal direction, connecting the driven gear 15 and the connecting rod 14 respectively.

[0073] The connecting rod 14 is arranged transversely to the longitudinal direction, connecting the driven wheel eccentric rod 17 and the drive shaft eccentric rod 13 respectively. Figure 5 As can be seen, the connecting rod 14 has a first hole 18 and a second hole 19. One end of the driven wheel eccentric rod 17 is inserted into the first hole 18, and the center of the first hole 18 is offset relative to the rotation center of the driven wheel 15. The driven wheel eccentric rod 17 is configured to connect the first hole 18 with the center offset and the driven wheel 15 together, which also constitutes the drive arm of the planar four-bar linkage.

[0074] The drive shaft eccentric rod 13 connects the connecting rod 14 and the drive shaft connecting rod 12. The distal end of the drive shaft eccentric rod 13 is inserted into the second hole 19 of the connecting rod 14. The drive shaft eccentric rod 13 is also arranged substantially in the longitudinal direction and is offset to one side of the drive shaft 11.

[0075] The drive shaft connecting rod 12 is connected to the drive shaft eccentric rod 13 and the drive shaft 11 respectively. Similar to the connecting rod 14, the drive shaft connecting rod 12 also has a first hole and a second hole separated by a certain distance, wherein the drive shaft eccentric rod 13 is inserted into the first hole, and the distal end of the drive shaft 11 is inserted through the second hole.

[0076] In particular, such as Figure 3 and Figure 4 As shown, in this invention, the central axis of the second hole of the drive shaft connecting rod 12 of the linkage mechanism 7 is substantially aligned with the rotation axis of the drive wheel 16. That is, the longitudinal axis L1 of the drive shaft 11 inserted into the second hole is substantially aligned with the longitudinal axis of the output shaft connected to the motor 10. It should be noted that, in this invention, "substantially aligned" means that the two axes are on a straight line or that the distance between them being parallel and offset is less than 1 mm.

[0077] Figure 5 A schematic diagram of a four-bar linkage consisting of the aforementioned linkage mechanism 7 is shown. Figure 5In the diagram, point O is the center of drive shaft 11, point A is the center of the second hole of connecting rod 14, point B is the center of the first hole of connecting rod 14 (which is also the location of the central axis of the driven wheel eccentric shaft), and point C is the rotation center of driven wheel 15. The rotation of the output shaft of motor 10 drives the drive wheel 16 to rotate, and the drive wheel 16 meshes with and drives the driven wheel 15 to rotate around point C. The driven wheel 15 is fixed to the driven wheel eccentric rod 17, and the rotation of the driven wheel 15 drives the driven wheel eccentric rod 17 to rotate around point C as well. Since the center point B of the first hole of connecting rod 14 is offset relative to point C, and the position of point O is fixed, as the driven wheel eccentric rod 17 rotates around point C, the rotation of the driven wheel eccentric rod 17 drives the connecting rod 14, drive shaft eccentric rod 13, and drive shaft connecting rod 12 to reciprocate around point C, thereby driving the drive shaft 11 to reciprocate around point O, thus realizing the reciprocating motion of the brush head 2 mounted on the drive shaft 11. In summary, the drive shaft 11, drive shaft connecting rod 12, connecting rod 14, driven wheel 15, and driven wheel eccentric rod 17 constitute a planar four-bar linkage structure, such as... Figure 5 As shown, the line connecting the center C of the driven wheel 15 to the center of the hole 18 of the connecting rod 14 forms a planar four-bar linkage drive arm, which can rotate continuously 360 degrees, thereby realizing the reciprocating rotation of the drive shaft 11 around the longitudinal axis.

[0078] The frame 20 is disposed adjacent to the motor 10 within the housing, specifically, as Figure 6 and Figure 7 The frame 20 has a bottom wall and an outer wall. Inside the outer wall, a first boss 24 and a second boss 23 protrude substantially longitudinally from the bottom wall. The first boss 24 has a first boss wall forming a first boss cavity 30, while the second boss 23 has a second boss wall forming a hole 21. The first boss cavity 30 primarily accommodates a drive wheel 16, which can rotate within the cavity. The hole 21 accommodates the end of a drive shaft 11, which can rotate within the hole of the second boss. Figure 6 As shown, the second boss 23 is stacked on top of the first boss 24 in the longitudinal direction, such that the hole 21 is located above the cavity of the first boss 30. Preferably, the hole 21 is located directly above the cavity of the first boss 30, that is, the entire hole 21 is located in the space area above the longitudinal direction of the cavity of the first boss 30, so that the output shaft and drive shaft 11 with substantially aligned axes can be maintained and accommodated by the same frame 20.

[0079] from Figure 3As can be seen, a boss hole bottom 22 is provided between the first boss 24 and the second boss 23. The upper surface of the bottom 22 abuts against the end of the drive shaft 11, thereby providing positioning and support for the drive shaft 11. In a preferred embodiment of the present invention, the boss hole bottom 22 is integrally formed with the wall of the second boss, thus becoming part of the second boss 23. However, it should be understood that in other alternative embodiments, the boss hole bottom may also be integrally formed with the first boss 24, for example, as part of the top of the second boss 23. Obviously, the first boss 24, the second boss 23, and the boss hole bottom can also be integrally formed.

[0080] Furthermore, such as Figure 6 The frame bottom wall 27 forms a boss bottom hole 25 on the side of the first boss 24 near the motor 10, allowing the output shaft of the motor 10 to extend into the first boss cavity 30 through the boss bottom hole 25. Figure 3 As shown, in a preferred embodiment of the invention, the diameter of the boss bottom hole 25 is set slightly larger than that of the drive wheel 16, and a portion of the drive wheel 16 extends through the bottom hole 25. It should be understood that in other alternative embodiments, the boss bottom hole 25 may also be set smaller, allowing only the output shaft of the motor 10 to pass through.

[0081] In addition, a notch is specially provided on the first boss wall 28, from... Figure 3 , Figure 6 As can be clearly seen, the driving wheel 16 located inside the first boss cavity 30 and the driven wheel 15 located substantially outside the boss cavity 30 can mesh with each other thanks to the space provided by the notch.

[0082] The bottom wall 27 of the frame and the frame cover 26 are also provided with two openings, which are preferably positioned vertically to receive the near end and far end of the driven wheel eccentric rod 17, respectively, and allow the driven wheel eccentric rod 17 to rotate under the drive of the driven wheel 15.

[0083] When the linkage mechanism 7 is installed inside the frame 20, the driving wheel 16, mounted on the motor output shaft, is located inside the first boss cavity 30, and the driven wheel 15 is located in the space between the outside of the first boss cavity 30 and the outer wall 29 of the frame. The connecting rod 14 and the drive shaft eccentric rod 13 are located in the space between the second boss wall and the outer wall 29 of the frame. The drive shaft connecting rod 12 extends laterally in the space between the top of the second boss 23 and the bottom of the frame cover 26, and one end of it, through the hole of the drive shaft 11, is located above the second boss 23.

[0084] In addition, such as Figure 3The second boss 23 and the first boss 24 are preferably formed as independent components, with the bottom of the second boss 23 engaging with the top of the first boss 24. It should be understood that in other alternative embodiments, the first boss 24 and the second boss 23 may also be formed as a single unit and fixedly assembled with the bottom wall of the frame. The first boss 24 and the second boss 23 may also be injection molded integrally with the frame 20.

[0085] According to a preferred embodiment of the invention, the frame 20 provides a compact arrangement by mounting the linkage mechanism 7 and the drive shaft 11 with two overlapping bosses. Particularly advantageously, in this invention, the longitudinal axis of the brush head 2 of the electric toothbrush 100 and the longitudinal axis of the handle can be substantially aligned, and the same frame 20 keeps the drive shaft 11 substantially aligned with the output shaft of the motor 10, ensuring accurate positioning and convenient installation.

[0086] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any variations and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the invention, fall within the protection scope defined by the claims of the present invention.
