Abstract
Description
Handles for handheld devices and electric toothbrushes Technical Field
[0001] The present application relates to the technical field of electric toothbrushes, and in particular to a handle of a handheld device and an electric toothbrush. Background Art
[0002] Handheld appliances such as electric toothbrushes, electric shavers, and electric hair clippers are increasingly becoming common household cleaning and care appliances. In order to make existing electric toothbrushes fully waterproof, the outer peripheral surface of the handle shell of the handheld appliance is generally not provided with any through holes, or the outer peripheral surface of the handle shell of the handheld appliance has holes, the holes are filled and no keycaps are installed. In this way, in order to trigger the keys inside the handle shell, it can only be achieved by the overall deformation of the handle shell.
[0003] However, there is a certain gap between the handle shell of the existing handheld device and the machine button inside the handle shell. At the same time, the handle shell itself has a certain strength. If the pressing force applied to the handle shell is too large and if the pressing area is inaccurate, it is easy to cause the button to be triggered by mistake. If the pressing force applied to the handle is too small, the button will not be triggered, so it is urgent to solve this problem.

[0035] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0037] Please refer to Figures 1 to 5. The present invention provides a handle 100 of a handheld device, which includes a shell 10, a main control board 20 and a flexible pad 30; wherein the shell 10 is cylindrical and defines a mounting cavity 10a, the outer peripheral surface of the shell 10 is continuously extended in the axial and circumferential directions, and the shell 10 is formed with a pressing area 10b, a gripping area 10c and a transition area 10d located between the pressing area 10b and the gripping area 10c; the main control board 20 is installed in the mounting cavity 10a, and the main control board 20 is provided with an input button 21 and an anti-false touch button 22, the input button 21 is provided corresponding to the pressing area 10b, and the anti-false touch button 22 is provided corresponding to the transition area 10d; the flexible pad 30 is installed in the mounting cavity 10a, and the flexible pad 30 is located between the pressing area 10b and the input button 21 and between the transition area 10d and the anti-false touch button 22.
[0038] The housing 10 can serve as a handle for the user to hold. The housing 10 is typically in the shape of an elongated strip. The cross-section of the housing 10 can be circular, elliptical, hexagonal, octagonal, or other shapes. The housing 10 can be made of a variety of materials. The housing 10 can be entirely made of plastic, or can be made of plastic and metal through secondary injection molding, or can be entirely made of metal. No specific limitations are set here.
[0039] The cavity wall profile of the mounting cavity 10a within the housing 10 can be varied. The cavity wall profile of the mounting cavity 10a can be inconsistent with the outer surface profile of the housing 10, or it can be consistent with the outer surface profile of the housing 10. It should be noted that when the housing 10 is formed using an injection molding process, the cavity wall profile of the mounting cavity 10a is consistent with the outer surface profile of the housing 10. This configuration facilitates the production of the housing 10 using the injection molding process.
[0040] The outer circumference of the housing 10 extends continuously in the axial and circumferential directions, that is, the outer circumference of the housing 10 is a continuously extending surface, that is, the outer circumference of the housing 10 does not have any hollow structures. This configuration ensures that the housing 10 can be immersed in water or operate in a vaporous environment, thereby facilitating cleaning of the housing 10 and expanding the range of environments in which the housing 10 can be used. The housing 10 is provided with a pressing area 10b, a gripping area 10c, and a transition area 10d located between the pressing area 10b and the gripping area 10c. The gripping area 10c is intended for a user to grip, and the pressing area 10b is intended for a user to press with their thumb. This configuration facilitates the user's gripping of the housing 10 and also facilitates the user's pressing of the pressing area 10b on the housing 10.
[0041] The main control board 20 is fixedly mounted within the mounting cavity 10a. There are various ways to secure the main control board 20, including screws, gluing, snap-fitting, and other methods. The main control board 20 can also be compressed within the mounting cavity 10a using other structural members. The method for securing the main control board 20 is not limited herein. The input buttons 21 and the anti-accidental touch button 22 on the main control board 20 can be of various types. These can be mechanical buttons, strain gauge force sensors, or other types of push-buttons, all of which are omitted here.
[0042] The flexible pad 30 can be made of silicone, rubber, or other materials with good deformation ability. There are many ways to fix the flexible pad 30. The flexible pad 30 can be clamped and fixed by the main control board 20 and the cavity wall of the installation cavity 10a. The flexible pad 30 can also be fixed between the cavity wall of the installation cavity 10a and the installation board surface of the main control board 20 by screw connection, glue bonding, plug-in, or other methods. There is no limitation on the fixing method of the flexible pad 30. There are many shapes of the flexible pad 30. The flexible pad 30 can be set in a flat plate shape, a U-shape, or an O-shape. It is sufficient to ensure that the flexible pad 30 can fill the gap between the pressing area 10b and the input key 21 and the gap between the transition area 10d and the anti-mistouch key 22.
[0043] When the handheld device equipped with the handle 100 of the handheld device is in operation, when the pressing area 10b of the housing 10 is deformed toward the inside of the mounting cavity 10a by an external force, the flexible pad 30 is deformed by the external force and simultaneously transmits the force to the input button 21 corresponding to the pressing area 10b. When the input button 21 is triggered by the flexible pad 30, it inputs a control command to the main control board 20, thereby controlling the operation of the handheld device. When the anti-accidental touch area of the housing 10 is deformed toward the inside of the mounting cavity 10a by an external force, the flexible pad 30 is deformed by the external force and simultaneously transmits the force to the anti-accidental touch button 22 corresponding to the anti-accidental touch area. When the anti-accidental touch button 22 is triggered, it sends an anti-accidental touch command to the main control board 20, thereby controlling the handheld device to maintain its original state.
[0044] The present invention defines an installation cavity 10a in a shell 10, and forms a gripping area 10c, a pressing area 10b, and a transition area 10d located between the gripping area 10c and the pressing area 10b on the shell 10; a main control board 20 is installed in the installation cavity 10a, and the main control board 20 is provided with an input button 21 corresponding to the pressing area 10b and an anti-mistouch button 22 corresponding to the transition area 10d; a flexible pad 30 is installed in the installation cavity 10a, and the flexible pad 30 elastically abuts against the input button 21 and the pressing area 10b, respectively, and the flexible pad 30 elastically abuts against the anti-mistouch button 22 and the transition area 10d, respectively.
[0045] Such a setting, on the one hand, avoids the problem of empty travel when the pressing area 10b is pressed, which in turn causes the input key 21 to be insensitive; at the same time, when the position of the flexible pad 30 relative to the pressing area 10b is pressed or the position of the flexible pad 30 relative to the transition area 10d is pressed, the flexible pad 30 is only locally deformed, which avoids the problem of the flexible pad 30 being subjected to force at a certain point and moving as a whole toward the main control board 20, thereby avoiding the problem of the anti-false touch button 22 being triggered when the pressing area 10b is pressed or the input key 21 being triggered when the transition area 10d is pressed; in addition, the flexible pad 30 is arranged between the main control board 20 and the housing 10, and can also play a role in reducing shock and noise. Please refer to Figures 1 to 3. In some embodiments of the present invention, the main control board 20 includes a main body 23, a first elastic arm 24 and a second elastic arm 25. The first elastic arm 24 and the second elastic arm 25 are both connected to the main body 23. The first elastic arm 24 is set corresponding to the pressing area 10b, and the second elastic arm 25 is set corresponding to the transition area 10d; the input button 21 and the anti-mistouch button 22 are both strain-type force sensors. The input button 21 is arranged at the position where the first elastic arm 24 is connected to the main body 23, and the anti-mistouch button 22 is arranged at the position where the second elastic arm 25 is connected to the main body 23.
[0046] Based on the above scheme, since the strain-type force sensor has the advantage of sensitive response, when the first elastic arm 24 produces a slight elastic deformation, the input button 21 can be triggered. Similarly, when the second elastic arm 25 produces a slight deformation, the anti-mistouch button 22 can be triggered. This improves the sensitivity of the input button 21 and the anti-mistouch button 22, which is beneficial to the triggering of the input button 21 and also helps to avoid erroneous operations.
[0047] It is worth noting that both the first elastic arm 24 and the second elastic arm 25 have a certain length. When a force of the same magnitude and direction is applied to all portions of the first elastic arm 24, the first elastic arm 24 experiences the greatest deformation when the force acts on its free end. Similarly, when a force of the same magnitude and direction is applied to all portions of the second elastic arm 25, the second elastic arm 25 experiences the greatest deformation when the force acts on its free end.
[0048] In view of this, in some embodiments of the present invention, the free end of the first elastic arm 24 is arranged opposite to the pressing area 10b, and the free end of the second elastic arm 25 is arranged opposite to the transition area 10d. Such an arrangement makes the input button 21 and the anti-mistouch button 22 easier to be triggered, thereby further improving the sensitivity of the input button 21 and the anti-mistouch button 22.
[0049] It should be noted that there are many ways to arrange the first elastic arm 24 and the second elastic arm 25. For example, the first elastic arm 24 and the second elastic arm 25 can be extended from the same side of the main body 23. For example, the first elastic arm 24 and the second elastic arm 25 can also be arranged at two opposite ends of the main body 23. Of course, the first elastic arm 24 and the second elastic arm 25 can also be arranged in other ways, which are not listed here.
[0050] Please refer to Figure 3. In some embodiments of the present invention, the main body 23 is penetrated by two first avoidance holes 23a and a second avoidance hole 23b. The first avoidance hole 23a and the second avoidance hole 23b can be round holes, square holes and holes of other shapes. Preferably, the first avoidance hole 23a and the second avoidance hole 23b are both bar holes; the first avoidance hole 23a is arranged around the free end of the first elastic arm 24. Preferably, the first elastic arm 24 is installed in the first avoidance hole 23a, and one end of the first elastic arm 24 is connected to the hole wall of the first avoidance hole 23a. Preferably, the second avoidance hole 23b is arranged around the free end of the second elastic arm 25, that is, the second elastic arm 25 is installed in the second avoidance hole 23b, and one end of the second elastic arm 25 is connected to the hole wall of the second avoidance hole 23b.
[0051] This arrangement, on the one hand, allows the first elastic arm 24 and the second elastic arm 25 to be concealed within the body 23, thus preventing the first elastic arm 24 and the second elastic arm 25 from protruding laterally from the body 23. This makes the overall structure of the main control board 20 more compact and facilitates the secure installation of the main control board 20. On the other hand, during the production of the main control board 20, only two U-shaped holes need to be drilled in the body 23 of the main control board 20 to obtain the first elastic arm 24 and the second elastic arm 25, thus facilitating the production of the main control board 20.
[0052] Referring to Figures 1 to 3 , in some embodiments of the present invention, the pressing region 10b and the transition region 10d are arranged axially along the housing 10; the first elastic arm 24 and the second elastic arm 25 both extend axially along the housing 10. This arrangement reduces the width of the main body 23 of the main control board 20 while also ensuring that the first and second elastic arms 24, 25 are sufficiently long, thereby facilitating elastic deformation of the first and second elastic arms 24, 25.
[0053] Please refer to Figures 4 to 6. In some embodiments of the present invention, the flexible pad 30 includes a main body 31, a first convex bump 32 and a second convex bump 33; wherein the main body 31 is arranged between the main control board 20 and the cavity wall of the installation cavity 10a, the first convex bump 32 and the second convex bump 33 are arranged on the side of the main body 31 facing the main control board 20, the end of the first convex bump 32 away from the main body 31 contacts the first elastic arm 24, and the end of the second convex bump 33 away from the main body 31 contacts the second elastic arm 25.
[0054] In this arrangement, the main body 31 of the flexible pad 30 is spaced apart from the main body 23 of the main control board 20, thereby avoiding the problem of the main body 31 of the flexible pad 30 pressing against the main body 23 of the main control board 20 due to external force; at the same time, the flexible pad 30 presses against the first elastic arm 24 through the first convex bump 32 and presses against the second elastic arm 25 through the second convex bump 33, so that the force can be concentrated, thereby making it easier for the first elastic arm 24 and the second elastic arm 25 to be pressed against the edge, which is beneficial to improving the sensitivity of the input button 21 and the anti-mistouch button 22.
[0055] Based on the above embodiment, the main control board 20 includes a main body 23, a first elastic arm 24 and a second elastic arm 25. The main body 23 is penetrated by a first avoidance hole 23a and a second avoidance hole 23b. The first avoidance hole 23a is arranged around the free end of the first elastic arm 24. Preferably, the first elastic arm 24 is installed in the first avoidance hole 23a, and one end of the first elastic arm 24 is connected to the hole wall of the first avoidance hole 23a; the second avoidance hole 23b is arranged around the free end of the second elastic arm 25. Preferably, the second elastic arm 25 is installed in the second avoidance hole 23b, and one end of the second elastic arm 25 is connected to the hole wall of the second avoidance hole 23b.
[0056] The width of the first convex bump 32 is smaller than the first avoidance hole 23a, and the width of the second convex bump 33 is smaller than the second avoidance hole 23b. In this way, the first convex bump 32 is set to fit with the first avoidance hole 23a, and the second convex bump 33 is set to fit with the second avoidance hole 23b. In this way, the first convex bump 32 and the second convex bump 33 are avoided from contacting with the main body 23 of the main control board 20, which leads to the problem of not being able to press the first elastic arm 24 and the second elastic arm 25 normally.
[0057] Please refer to Figures 5 and 6. In some embodiments of the present invention, the flexible pad 30 also includes a third bulge 34 and a fourth bulge 35. The third bulge 34 and the fourth bulge 35 are both located on the side of the main body 31 facing away from the main body 23 of the main control board 20. The third bulge 34 is set corresponding to the first bulge 32, the third bulge 34 is set corresponding to the pressing area 10b, the fourth bulge 35 is set corresponding to the second bulge 33, and the fourth bulge 35 is set corresponding to the transition area 10d.
[0058] This arrangement reduces the contact area between the flexible pad 30 and the pressing area 10b and the transition area 10d. This prevents the input button 21 from being triggered by pressing the position adjacent to the pressing area 10b when the user holds the housing 10. It also reduces the possibility of the anti-false touch button 22 being triggered by pressing the position adjacent to the transition area 10d of the housing 10.
[0059] Furthermore, the first convex bulge 32 and the third convex bulge 34 are arranged back to back, and the cross-section of the first convex bulge 32 is smaller than the cross-section of the third convex bulge 34, that is, the projection of the first convex bulge 32 on the main body 31 in the direction of the main body 31 away from the main control board 20 is smaller than the projection of the third convex bulge 34 on the main body 31 in the direction of the main body 31 close to the main control board 20; the second convex bulge 33 and the fourth convex bulge 35 are arranged back to back, and the cross-section of the second convex bulge 33 is smaller than the cross-section of the fourth convex bulge 35, that is, the projection of the second convex bulge 33 on the main body 31 in the direction of the main body 31 away from the main control board 20 is smaller than the projection of the fourth convex bulge 35 on the main body 31 in the direction of the main body 31 close to the main control board 20.
[0060] With such a configuration, when the third convex bump 34 is acted upon by an external force, the external force can be concentrated when it is transmitted to the first convex bump 32, so that it is convenient to trigger the input button 21 by applying a force to the pressing area 10b. Similarly, when the fourth convex bump 35 is acted upon by an external force, the external force can also be concentrated when it is transmitted to the second convex bump 33, so that it is convenient to apply a force to the transition area 10d to trigger the anti-mistouch button 22.
[0061] Please refer to Figure 4. In some embodiments of the present invention, the first convex bump 32 and the second convex bump 33 are respectively connected to the middle position of the main body 31. The edge of the main body 31 is provided with a support boss 36 extending toward the body 23 of the main control board 20. The support boss 36 can be arranged in a strip shape or a ring shape. When the support boss 36 is arranged in a strip shape, the number of the support boss 36 is multiple. When the support boss 36 is arranged in a ring shape, the number of the support boss 36 can be one.
[0062] This arrangement allows the edge of the main body 31 to abut against the body 23 of the main control board 20 via the support boss 36, while the middle area of the main body 31 abuts against the body 23 of the main control board 20 via the first and second convex bumps 32, 33. This ensures that the main body 31 and the body 23 of the main control board 20 are always spaced apart, ensuring that the main body 31 does not affect the electronic components on the main control board 20. Furthermore, the spacing between the main control board 20 and the main body 31 facilitates heat dissipation from the main control board 20. Furthermore, the support boss 36 of the flexible pad 30 abuts against the body 23 of the main control board 20, while the third and fourth convex bumps 34, 35 of the flexible pad 30 abut against the walls of the mounting cavity 10a, respectively. This further facilitates positioning of the main control board 20 and facilitates its installation.
[0063] Based on the above embodiments, referring to FIG. 2 , in some embodiments of the present invention, the housing 10 has a first end 11 and a second end 12 disposed opposite each other. The first end 11 of the housing 10 is used to connect to the working head of the handheld device. The pressing region 10b, the transition region 10d, and the gripping region 10c are sequentially disposed in the axial direction of the housing 10, with the pressing region 10b disposed adjacent to the first end 11 and the gripping region 10c disposed adjacent to the second end 12. This arrangement facilitates the user's gripping of the housing 10 and also facilitates the user's ability to press the pressing region 10b while gripping the housing 10, thereby facilitating user use.
[0064] It is worth noting that the working head of the handheld device is related to the type of handheld device. For example, when the handheld device is an electric toothbrush, the working head is a toothbrush. For another example, when the handheld device is a razor, the working head is a razor head. For another example, when the handheld device is a massager, the working head is a massage head, and so on. I will not list them one by one here.
[0065] The present invention also provides an electric toothbrush comprising a handheld handle 100.
