Detailed Implementation

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0027] like Figure 1-3As shown, an embodiment of this utility model provides a handheld vibrator, which includes: a housing 1, a motor 2, and a shock-absorbing device 3. The inner wall of the housing 1 is provided with a plurality of protrusions 11 that protrude from the inner wall surface. The motor 2 is fixed inside the housing 1. The shock-absorbing device 3 is sleeved on the motor 2 and the outer surface of the shock-absorbing device 3 abuts against the inner wall of the housing 1. The outer surface of the shock-absorbing device 3 is provided with a plurality of grooves 31 that correspond one-to-one with and engage with the protrusions 11.

[0028] In this utility model, in addition to abutting against the inner wall of the housing 1, the shock-absorbing device 3 also engages with the protruding body protruding from the inner wall of the housing 1 through the groove 31, thereby achieving stable fixation of the shock-absorbing device 3. This effectively prevents the shock-absorbing device 3 from moving under the vibration of the motor 2, ensuring the shock-absorbing effect.

[0029] Specifically, the housing 1 includes a cylindrical body 12 without caps at both ends, a first cap 13, and a second cap 14. The first cap 13 is detachably connected to one end of the cylindrical body 12, and the second cap 14 is detachably connected to the other end of the cylindrical body 12. The motor 2 is fixed inside the cylindrical body 12, and the protrusion 11 is provided on the inner wall of the cylindrical body 12. In this design, the housing 1 is designed as a three-section detachable structure. When the motor 2 is damaged or the shock absorber 3 is worn out and needs to be replaced, the first cap 13 or the second cap 14 can be disassembled from the cylindrical body 12 to replace the motor 2 and the shock absorber 3.

[0030] It should be noted that, in order to enhance the shock absorption effect, there are two shock absorption devices. The shock absorption device 3 is arranged along the length of the cylinder 12 and sleeved on the motor 2. Correspondingly, the protrusion 11 forms a first protrusion 11a and a second protrusion 11b that respectively engage with the two shock absorption devices 3.

[0031] Furthermore, the inner wall of the first cover 13 extends to form a first connecting post 131 that is detachably connected to the first protrusion 11a. The purpose of this design is to make full use of the internal structure of the cylinder 12. Unlike the prior art where the connecting structure is set on the outer surface, this application embeds the connecting component between the first cover 13 and the cylinder 12 inside the cylinder 12. On the one hand, this can protect the connecting structure and make its connection stable; on the other hand, it makes the outer surfaces of the first cover 13 and the cylinder 12 clean and simple, improving the visual appeal.

[0032] There are multiple ways to connect the first connecting post 131 and the first protrusion 11a. In some feasible embodiments, the first protrusion 11a is provided with a locking groove that matches the end of the first connecting post 131. When connecting, the end of the first connecting post 131 extends into the locking groove and forms a lock, thereby fixing the first cover 13 and the cylinder 12.

[0033] In this embodiment, the first connecting post 131 is provided with a first through hole, and the first protrusion 11a is provided with a first threaded through hole that mates with the first through hole. The first connecting post 131 is connected to the first protrusion 11a by bolts.

[0034] Furthermore, the first cover 13 has several heat dissipation holes 132 at its end. The heat generated by the motor 2 inside the housing 1 during operation can be dissipated through the heat dissipation holes 132.

[0035] Furthermore, the surface of the first cover 13 adopts a curved transition. The purpose of this design is to reduce the sharp edges of the shell 1. When massaging, the shell 1 comes into contact with the human body surface, reducing discomfort.

[0036] Furthermore, the inner wall of the second cover 14 extends to form a second connecting post 141 that is detachably connected to the second protrusion 11b. The purpose of this design is to fully utilize the internal structure of the cylinder 12. Unlike existing technologies where the connecting structure is located on the outer surface, this application integrates the connecting component between the second cover 14 and the cylinder 12 within the cylinder 12. This protects the connecting structure, ensuring a stable connection, and also makes the outer surfaces of the second cover 14 and the cylinder 12 clean and simple, improving visual appeal.

[0037] There are multiple ways to connect the second connecting post 141 and the second protrusion 11b. In some feasible embodiments, the second protrusion 11b is provided with a locking groove that matches the end of the first connecting post 131. When connecting, the end of the second connecting post 141 extends into the locking groove and forms a lock, thereby fixing the second cover 14 to the cylinder 12.

[0038] In this embodiment, the second connecting post 141 is provided with a second through hole, and the second protrusion 11b is provided with a second threaded through hole that mates with the first through hole. The second connecting post 141 is connected to the second protrusion 11b by bolts.

[0039] Furthermore, a protrusion 142 protrudes from the outer surface of the second cover 14. The protrusion 142 has several functions: 1. When the cylinder 12 or the first cover 13 comes into contact with the part of the human body to be massaged, the protrusion 142 can be used as a grip; 2. The protrusion 142 can be used as a massage end to massage a local part of the human body.

[0040] Furthermore, the end of the protrusion 142 and the connection between the protrusion 142 and the surface of the second cover 14 are curved. The purpose of this design is to reduce the sharp edges of the housing 1 and improve the comfort of the massage.

[0041] Furthermore, the cross-sectional area of ​​the protrusion 142 gradually decreases in the direction away from the motor 2. The purpose of this design is to make the protrusion 142 form a smaller end, so that a deeper massage can be performed during massage.

[0042] Furthermore, the outer casing of the motor 2 is provided with an annular groove that matches the shock-absorbing device 3. The shock-absorbing device 3 is sleeved on the outer casing of the motor 2 and engaged within the annular groove. The purpose of this design is to limit the movement of the shock-absorbing device 3 relative to the motor 2, thereby further resolving the issue of movement of the shock-absorbing device 3 relative to the motor 2.

[0043] Specifically, the shock absorber 3 is annular and is sleeved on the outer housing of the motor 2. The inner annular surface of the shock absorber 3 is engaged in the annular groove, and the groove 31 is formed on the outer peripheral surface of the shock absorber 3. The outer peripheral surface of the shock absorber 3 abuts against the inner wall of the housing 1.

[0044] Furthermore, the shock-absorbing device 3 is made of flexible materials, such as rubber, silicone, etc.

[0045] Furthermore, several blind holes 32 are provided on both end faces of the shock absorber 3. The blind holes 32 serve to: 1. reduce the weight of the shock absorber 3, and 2. enhance the deformation capacity of the shock absorber 3, thereby increasing the shock absorption effect of the shock absorber 3.

[0046] Furthermore, the present invention also includes a control module 4, which is fixed on the cylinder 12 and electrically connected to the motor 2 for controlling the working state of the motor 2.

[0047] Furthermore, the present invention also includes a display module 5, which is embedded in the second cover 14 and electrically connected to the control module 4. The control module 4 sends a signal to the display module 5 to drive the display module 5 to display the working status of the motor 2.

[0048] Furthermore, a display through hole 143 is provided on the surface of the second cover 14, and the display module 5 is fixed on the surface of the second cover 14 facing the motor 2, with the display unit of the display module 5 embedded in the display through hole 143.

[0049] Furthermore, the end face of the second cover 14 is inclined relative to the axis of the cylinder 12. This design facilitates observation of the content displayed by the display module 5 during use.

[0050] Furthermore, a plurality of second heat dissipation holes 144 are provided on the end face of the second cover 14. The heat generated by the display module 5 during operation can be dissipated through the second heat dissipation holes 144.

[0051] It should be noted that in this solution, both the control module 4 and the display module 5 adopt existing solutions. For example, the control module 4 can be a common STM32F103 microcontroller module, and the display module 5 can be a common display module composed of multiple LEDs. The core inventive point of this application is not an improvement on the control module 4 and the display module 5, so it will not be elaborated here.

The motor is fixed inside the housing. The shock-absorbing device is sleeved on the motor, and its outer surface abuts against the inner wall of the housing. The outer surface of the shock-absorbing device has several grooves that correspond one-to-one with and engage with the protrusions. In addition to abutting against the inner wall of the housing, the shock-absorbing device is also stably fixed by engaging with the protrusions through the grooves, effectively preventing the shock-absorbing device from moving under the vibration of the motor and ensuring the shock absorption effect.

[0054] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto.
