Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, specifically to a protective sleeve and massage device. Background Technology

[0002] Massagers, as a common relaxation device, are widely used in daily health care scenarios such as relieving muscle tension and reducing fatigue.

[0003] Existing massagers are typically equipped with pressure sensors to detect the pressure applied and adjust the massage intensity. However, when users hold a massager, their movements are often unstable, and the pressure sensors can be accidentally triggered by even small forces, affecting the user experience.

[0004] Therefore, there is an urgent need to provide a protective cover and massage device to solve the above problems. Utility Model Content

[0005] In view of this, the present invention provides a protective sleeve and a massage device to solve the problem that the pressure sensor of the massager in the prior art is easily triggered by a small force during use.

[0006] To achieve one or more of the above objectives or other objectives, this utility model proposes a protective sleeve for a massager. The massager includes a massager body and at least one pressure sensing part disposed on the massager body. The protective sleeve includes at least one flexible pressing part, which is connected to the massager body and covers the pressure sensing part. An avoidance space is formed between the flexible pressing part and the pressure sensing part. The flexible pressing part can elastically deform towards the pressure sensing part and press against the pressure sensing part.

[0007] Preferably, the sheath includes at least two flexible pressing parts and a wrapping part connecting the flexible pressing parts, the wrapping part wrapping the massager body.

[0008] Preferably, the flexible pressing part is provided on the wrapping part in a direction away from the pressure sensing part, and the clearance space extends towards the flexible pressing part.

[0009] Preferably, the wrapping part has an annular groove surrounding the flexible pressing part, and the outer surface of the flexible pressing part has an anti-slip texture.

[0010] This utility model also proposes a massage device, including a massager and a protective cover. The massager further includes a first massage part disposed on the massager body. The cover has a first opening, and the first massage part is exposed from the first opening. The first opening extends away from the first massage part and is located between two flexible pressing parts.

[0011] Preferably, the massager also includes a vibration motor, which is located inside the main body of the massager and can drive the massager to vibrate.

[0012] Preferably, the massager further includes a second massage part, a connector, and a drive motor. The second massage part is disposed on the massager body, and the connector and drive motor are installed inside the massager body. The first end of the connector is connected to the drive motor, and the second end of the connector is connected to the second massage part.

[0013] Preferably, the second massage part has a protrusion that protrudes from the first opening and is recessed inward to form a hollow cavity, which opens in a direction away from the connector.

[0014] Preferably, the wrapping part covers the second massage part, and a protrusion is provided on the wrapping part corresponding to the second massage part. The protrusion is recessed inward to form a hollow cavity, and the hollow cavity opens in a direction away from the connector.

[0015] Preferably, the massager includes a hard shell, a soft shell, and two pressure sensors; the hard shell has mounting surfaces on both sides, and the pressure sensors are respectively mounted on the mounting surfaces; the soft shell encloses the hard shell and the pressure sensors.

[0016] Implementing the embodiments of this utility model will have the following beneficial effects:

[0017] By employing the aforementioned protective sleeve or massage device, the flexible pressing part and the pressure sensing part form a clearance space, effectively increasing the squeezing stroke of the pressure sensor. As a result, even if the user accidentally applies a small force during use, it will not be sufficient to trigger the pressure sensor's response, thus avoiding changes in vibration intensity due to misoperation and improving the device's stability and user experience.

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] See appendix Figure 1 This utility model proposes a protective sleeve 2 for a massager 1. The massager 1 includes a massager 1 body and at least one pressure sensing part 11 disposed on the massager 1 body. The protective sleeve 2 includes at least one flexible pressing part 21. The flexible pressing part 21 is connected to the massager 1 body and covers the pressure sensing part 11. An avoidance space 210 is formed between the flexible pressing part 21 and the pressure sensing part 11. The flexible pressing part 21 can elastically deform towards the pressure sensing part 11 and abut against the pressure sensing part 11.

[0036] The pressure sensing unit 11 is disposed on the massager body 10 and is used to sense the pressure applied by the user. Through the pressure sensing unit 11, the massage device can adjust the vibration or massage intensity according to the different pressure applied by the user. Specifically, the massager 1 has a circuit assembly, which includes a circuit board and a controller disposed on the circuit board. The pressure sensing unit 11 can sense different pressure levels by using a pressure sensor 110. The pressure sensor 110 deforms under the action of pressure, causing a change in its resistance, which in turn causes a change in current. The pressure sensor 110 is electrically connected to the controller, and the controller controls the working intensity of the massage device according to the detected change in current.

[0037] Depending on the user's different usage scenarios, the massager 1 may be equipped with multiple pressure sensors 11. These pressure sensors 11 are distributed in different positions on the massager body 10 to meet the user's needs under different grip methods or usage angles.

[0038] For example, in one embodiment, pressure sensing units 11 are symmetrically arranged on both sides of the massager 1. The user fixes the massage device by holding or clamping it, and squeezes the two pressure sensing units 11 from both sides of the massager 1. Each pressure sensing unit 11 can detect the pressure value applied by the user, and the massager 1 adjusts the vibration or massage intensity according to the pressure value.

[0039] See appendix Figures 1 to 3The sheath 2 is installed on the outside of the massager 1, so that the flexible pressing part 21 covers the pressure sensing part 11. During use, when the user consciously applies pressure to the flexible pressing part 21, the flexible pressing part 21 will elastically deform, pressing against the pressure sensing part 11 and transmitting the pressure to the pressure sensing part 11, thereby triggering the corresponding function adjustment. When the user accidentally touches the flexible pressing part 21, the small force generated by the accidental touch is insufficient to eliminate the clearance space 210. In other words, under the action of the flexible pressing part 21, the accidental touch will not trigger the response of the pressure sensing part 11, improving the stability of the massage device.

[0040] In addition, the flexible pressing part 21 can be made of materials with a certain degree of elasticity and flexibility, such as silicone or rubber. On the one hand, it can deform under force and recover after the force is removed. On the other hand, it has a skin-friendly effect and increases the comfort of massage.

[0041] Further, see appendix. Figures 2 to 3 The sheath 2 includes at least two flexible pressing parts 21 and a wrapping part 22 connecting the flexible pressing parts 21, the wrapping part 22 wrapping the massager body 10.

[0042] In this embodiment, the massager 1 has two pressure sensing parts 11, and the protective sleeve 2 is provided with two flexible pressing parts 21. The wrapping part 22 is wrapped and installed on the outer surface of the massager body 10. In addition to connecting the two flexible pressing parts 21, it can also protect the massager 1 and prevent the massager body 10 from being scratched and damaged during use.

[0043] To achieve a secure connection between the sheath 2 and the massager 1, adhesive can be used to bond the cover 22 to the massager body 10, or the two can be connected by designing a sleeve structure between the cover 22 and the massager body 10, or the massager body can simply be wrapped in the cover. The following provides a massage device in which the sheath 2 can be detachably connected to the massager 1:

[0044] Specifically, see the appendix. Figure 1 The massager 1 includes a first massage part 12 disposed on the massager body 10. The cover 22 has a first opening 222 through which the first massage part 12 protrudes. The first massage part 12 is the main working part of the massage device, directly contacting the user's skin to achieve massage effects such as vibration, kneading, and tapping. Therefore, the first massage part 12 protrudes from the cover 2, ensuring that the massage function is not obstructed.

[0045] To secure the sheath 2 to the massager 1, the first opening 222 needs to be enlarged, extending away from the first massage part 12. Specifically, the first opening 222 extends from the top of the covering part 22 towards the bottom, and is located between the two flexible pressing parts 21. This extension of the first opening 222 increases the opening area, making it easier for the user to insert the massager 1 into the sheath 2 through the first opening 222 or remove it from the first opening 222.

[0046] During installation, the massager 1 is inserted into the protective sleeve 2 along the first opening 222. The protective sleeve 2 conforms to the massager 1 through the elasticity of its silicone material, thus completing the installation. During disassembly, the first opening 222 of the protective sleeve 2 is manually pulled open to remove the massager 1.

[0047] Further, see appendix. Figures 2 to 4 The flexible pressing part 21 is provided on the wrapping part 22 in a direction away from the pressure sensing part 11, and the clearance space 210 extends toward the flexible pressing part 21.

[0048] The protruding design of the flexible pressing part 21 eliminates the need for a recessed design for the pressure sensing part, and a uniform clearance space 210 is formed around the pressure sensing part 11. In addition, the massage device in this embodiment has a user guidance function: the flexible pressing part 21 protrudes from the surface of the wrapping part 22, which can visually and tactilely identify the position of the pressure sensing part 11, making it easy for the user to quickly identify and adjust the massage intensity.

[0049] Similarly, see appendix. Figure 3 To further enhance the user experience, the outer surface of the flexible pressing part 21 is designed with an anti-slip texture 211. Its specific functions are reflected in two aspects: First, the anti-slip texture 211 can increase the friction of the outer surface of the flexible pressing part 21, effectively preventing accidental slippage or displacement of the massage device when the user grips the massage device or when the massage device comes into contact with the human body; Second, the anti-slip texture 211, through tactile differences, further helps the user quickly identify the position of the pressure sensing part 11, guiding the user to adjust the massage intensity from a tactile perspective.

[0050] Further, see appendix. Figures 5 to 6 The wrapping part 22 is provided with an annular groove 221 surrounding the flexible pressing part 21. The annular groove 221 clearly separates the flexible pressing part 21 from the wrapping part 22 in terms of structure. Its function is to isolate the user when applying pressure, so that the force applied by the user is concentrated on the flexible pressing part 21.

[0051] Further, see appendix. Figure 2 and attached Figure 5The massager body 10 is equipped with control buttons 13; the wrapping part 22 has a second opening 223, which surrounds the control buttons 13.

[0052] The control button 13 is used to start, stop, or switch modes of the massage device. To enable users to easily operate the control button 13, the cover 22 has a second opening 223. The shape and size of the second opening 223 are adapted to the outer periphery of the control button 13 and are arranged in a surrounding manner, so that the control button 13 can be exposed from the second opening 223.

[0053] Furthermore, the massager 1 also includes a vibration motor 14, which is disposed inside the massager body 10 and can drive the massager 1 to vibrate.

[0054] The vibration motor 14 generates vibration through high-speed rotation or an eccentric structure, which drives the entire massager 1 to vibrate. The vibrating first massage part 12 comes into contact with the human body, thereby providing a comfortable massage effect. The sheath 2, made of flexible material, has a shock-absorbing effect. The sheath 2 wraps around the outside of the massager body 10, while the first massage part 12 is exposed. It can effectively buffer the vibration force generated by the vibration motor 14, reduce the transmission of vibration to the human body's gripping or clamping parts, and avoid discomfort caused by vibration diffusion when the user holds the device.

[0055] Further, see appendix. Figure 8 In other embodiments, the massager 1 further includes a second massage part 15, a connector 16, and a drive motor 17. The second massage part 15 is disposed on the massager body 10, and the connector 16 and the drive motor 17 are installed inside the massager body 10. The first end 161 of the connector 16 is connected to the drive motor 17, and the second end 162 of the connector 16 is connected to the second massage part 15.

[0056] The second massage part 15 is located on the main body 10 of the massager. When the massage device has two or more massage functions at the same time, the second massage part 15 and the first massage part 12 are two different parts that come into contact with the human body. The first massage part 12 is used for vibration massage, and the second massage part 15 is used for tapping or other massage methods.

[0057] The drive motor 17 serves as a power source to drive the movement of the connector 16. The first end 161 of the connector 16 is fixedly connected to the output end of the drive motor 17, and the second end 162 is connected to the second massage unit 15. When the drive motor 17 is started, it drives the connector 16 to move through rotation or reciprocating motion, thereby driving the second massage unit 15 to pat the user's skin.

[0058] Specifically, the connecting member 16 can be a crank-connecting rod mechanism, the output end of the motor is an eccentric shaft, and the crank-connecting rod mechanism is connected to the eccentric shaft to convert the rotation of the drive motor 17 into the reciprocating motion of the second massage part 15.

[0059] Furthermore, in one embodiment, the second massage portion 15 has a protrusion 151 that protrudes from the first opening 222, see attached drawing. Figure 9 The protrusion 151 is recessed inward to form a hollow cavity 150, which opens away from the connector 16. When the second massage part 15 performs a tapping motion under the action of the drive motor 17, alternating positive and negative pressure changes occur within the hollow cavity 150 with the tapping action. Specifically, when the second massage part 15 moves outward under the action of the connector 16, the volume of the hollow cavity 150 increases, and the internal gas pressure decreases, forming a negative pressure; when the second massage part 15 moves inward under the action of the connector, the volume of the hollow cavity 150 decreases, and the internal gas pressure increases, forming a positive pressure. This alternating change in positive and negative pressure is transmitted to the skin surface through contact with the user's skin, producing an effect similar to air pressure massage.

[0060] See appendix Figure 10 In another embodiment, the aforementioned air pressure massage is achieved by providing a protrusion 151 on the sheath 2. That is, the wrapping part 22 covers the second massage part 15, and a protrusion 151 is provided on the wrapping part 22 corresponding to the second massage part 15. The protrusion 151 is recessed inward to form a hollow cavity 150, and the hollow cavity 150 opens in a direction away from the connector 16. In other words, a portion of the surface of the massager 1 and the inner wall of the hollow cavity 150 provided on the sheath 2 together enclose a space that generates positive and negative pressure.

[0061] Further, see appendix. Figure 7 The massager 1 includes a hard shell 18, a soft shell 19 and two pressure sensors 110; the hard shell 18 has mounting surfaces 181 on both sides, and the two pressure sensors 110 are respectively mounted on the two mounting surfaces 181; the soft shell 19 is arranged to enclose the hard shell 18 and the pressure sensors 110.

[0062] The pressure sensor 110 measures the pressure applied to the massage device during use and converts it into an electrical signal, which is then fed back to the internal control system. The control system can adjust the intensity of the massage device based on the pressure data provided by the pressure sensor 110.

[0063] The rigid housing 18 of the massage device provides reliable housing space for the internal components, protecting them and providing stable support. In addition, the rigid housing 18 is connected to the vibration motor 14 and also transmits vibrations to the first massage section 12. In one embodiment, components such as the motor and control system are installed inside the rigid housing 18, while pressure sensors 110 are respectively installed on the mounting surfaces 181 on both sides of the rigid housing 18. The pressure sensors 110 can be attached to the mounting surfaces 181 by adhesive, fixed to the mounting surfaces 181 by mounting components such as screws, or fixed to the mounting surfaces 181 by designing an embedded structure.

[0064] The soft housing 19 can be made of materials such as silicone or TPE (Thermoplastic Elastomer), and is wrapped around the outside of the hard housing 18 and the pressure sensor 110. The soft housing 19 has two main functions: first, it can deform under force to transmit the squeezing force to the pressure sensor 110 mounted on the hard housing 18; second, it provides a comfortable touch and flexible protection.

[0065] The massage device has two usage forms: the massager 1 can be used in combination with the protective cover 2, and the massager 1 can be used alone. The soft shell 19 provides the structural basis for the massager 1 to be used alone, that is, the soft shell 19 encloses the electronic components located on or inside the hard shell 18. When the user removes the protective cover 2, the massager 1 can be used alone for massage. The soft material further provides the user with comfortable contact with the skin and a shock absorption effect.

[0066] In one embodiment, the massager 1 has both tapping and vibration massage functions. A first massage section 12 and a second massage section 15 are formed on the soft outer shell in different directions, respectively contacting the human body and providing vibration and tapping massage functions. The first massage section 12 provides vibration massage to the skin to be massaged via the vibration of the vibration motor 14. A third opening 182 is provided on the hard shell 18, and a connecting member 16 is connected to the drive motor 17. Through the third opening 182, the second massage section 15 reciprocates from inside the hard shell 18 to the soft shell 19 to provide tapping or air pressure massage to the skin to be massaged. The vibration motor 14 and the drive motor 17 may be the same motor located inside the massager 1. This motor is a dual-axis motor and contacts the hard shell 18. One shaft of the dual-axis motor is equipped with an eccentric block to generate vibration and transmit the vibration through the hard shell 18. The other shaft of the dual-axis motor is equipped with an eccentric shaft connected to a crank-connecting rod mechanism to drive the second massage section 15 in reciprocating motion. The vibration motor 14 and the drive motor 17 can also be two independent motors located inside the massager 1, providing vibration and tapping massage functions respectively.

[0067] In this embodiment, the massager body 10, pressure sensing part 11, first massage part 12, and second massage part 15 are all regions of the massager 1 divided according to their functional effects. Similarly, the flexible pressing part 21 and the wrapping part 22 are also regions of the protective sleeve 2 divided according to their functional effects.

[0068] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
