A first protrusion is disposed on the first massage surface, separating the first massage surface into a first surface and a second surface. The first protrusion also has a third surface. A first heating film covers the third surface. The direction from the third surface to the first massage surface is defined as a first direction. The projected area of ​​the first massage surface along the first direction is denoted as 'a'. The projected areas of the first surface, the second surface, and the third surface along the first direction are m1, m2, and m3, respectively, where 0.2a ≤ m1 ≤ 0.3a, 0.2a ≤ m2 ≤ 0.3a, and 0.4a ≤ m3 ≤ 0.6a.

Description

Technical Field

[0001] This application relates to the field of massager technology, and more particularly to a massager. Background Technology

[0002] With increasing demand for health, portable massagers, with their compact and portable design and ability to quickly relieve muscle fatigue, are gradually becoming common health and wellness devices in daily life. Portable massagers typically combine vibration, tapping, and heat therapy functions; in particular, the heat therapy function can promote blood circulation and enhance the massage effect. However, as portable devices, the operating time and portability of massagers are significantly limited by battery capacity. How to balance functionality and battery life within a limited device size is an important research direction in the industry.

[0003] Currently, most portable massagers employ a single, integrated heating design, where the heating element covers the entire massage head to achieve uniform overall heating. Common heating materials include graphene films and metal-ceramic heating elements, which are characterized by rapid heating and precise temperature control. To extend battery life, current technologies generally increase the device's battery capacity, compensating for the high power consumption of the integrated heating design by increasing energy reserves.

[0004] However, while existing technologies employ a unified heating design to provide even heat distribution, the heating method of enveloping the entire massage head results in non-contact areas also being heated. This large-area heating shortens the massager's battery life and causes unnecessary energy waste. Furthermore, solutions relying on increasing battery capacity to extend battery life are limited by the size and weight constraints of the massager, making it difficult to effectively improve battery performance. Therefore, there is an urgent need for a massager that can guarantee effective heating while simultaneously enhancing battery life to address these issues. Utility Model Content

[0005] In view of this, it is necessary to provide a massager that can ensure heating effect while enhancing battery life, in order to solve the above problems.

[0006] An embodiment of this application provides a massager, comprising:

[0007] The housing includes a handle and a first massage head movably connected to the handle, the first massage head including a body and a first massage surface disposed on the body;

[0008] A first protrusion is provided on the first massage surface. The first protrusion separates the first massage surface to form a first surface and a second surface. The side of the first protrusion facing away from the first massage surface has a third surface.

[0009] A first heating film covers the third surface;

[0010] Wherein, the direction from the third surface to the first massage surface is defined as the first direction, the projected area of ​​the first massage surface along the first direction is a, and the projected areas of the first surface, the second surface and the third surface along the first direction are m1, m2 and m3 respectively, satisfying 0.2a≤m1≤0.3a, 0.2a≤m2≤0.3a and 0.4a≤m3≤0.6 respectively.

[0011] In at least one embodiment of this application, m1 = 0.25a, ​​m2 = 0.25a, ​​and m3 = 0.5a.

[0012] In at least one embodiment of this application, the massager further includes a oscillating component;

[0013] The swing assembly includes a motor disposed in the handle and an eccentric member disposed on the motor. The side of the eccentric member facing away from the motor is disposed on the massage head. The eccentric member is used to drive the swing of the massage head. The first heating film is disposed along the swing direction of the massage head.

[0014] In at least one embodiment of this application, the first heating film includes a first heating element, a second heating element, and a third heating element disposed thereon;

[0015] The second heating element covers the third surface. Both the first heating element and the third heating element are disposed on the main body. The main body has a through groove, and the third heating element extends into the through groove to fix the first heating film.

[0016] In at least one embodiment of this application, the handle further includes two parallel limiting blocks, with a movable groove formed between the two limiting blocks, and is located at one end of the handle near the massage head;

[0017] The massager also includes a rotating component, which is disposed between the handle and the massage head. The rotating component is fixedly connected to the main body and is located in the movable groove, which is used to limit the swing direction of the massage head.

[0018] In at least one embodiment of this application, the first massage head further includes a fixing block, and a plurality of the fixing blocks are disposed on the inner surface of the massage head to form a fixing groove;

[0019] The massager also includes a vibration assembly, which includes a motor disposed in the massage head and an eccentric block disposed on the motor. The motor is disposed in the fixing groove, and the eccentric block is disposed at one end of the motor near the first massage surface for generating vibration.

[0020] In at least one embodiment of this application, the fixing blocks on opposite sides of the fixing groove respectively abut against the inner surface of the main body, and the fixing blocks and the main body enclose the vibration cavity.

[0021] In at least one embodiment of this application, the massager further includes a second massage head, one end of which is disposed on the handle and the other end is inclined outward.

[0022] The massager also includes a second heating film, and the second massage head is specifically a second massage surface. The second heating film covers the second massage surface along the length of the massage head.

[0023] In at least one embodiment of this application, the massager further includes a second protrusion disposed on the second massage surface, the side of the second protrusion facing away from the second massage surface being disposed on a fourth surface, and the second heating film covering the fourth surface.

[0024] In at least one embodiment of this application, the massager further includes a control mechanism, the control mechanism including a power supply component and a control component electrically connected to the power supply component;

[0025] The power supply component includes a power source and a mounting base. The mounting base is located at the bottom of the handle. The power source is fixedly connected to the mounting base and electrically connected to the first heating film to supply power to the first heating film.

[0026] The control component includes a control panel and a stepless adjustment device connected to the control panel for data transfer. The control panel is mounted on the fixed base, and the stepless adjustment device is located on the side of the fixed base away from the control panel, for adjusting the power of the first heating film.

[0027] The massager described above features protrusions on the massage surface. These protrusions are the first points of contact during massage, resulting in the best massage effect. By covering only the third surface—the side where the massage head protrusions contact the user—heat is concentrated in the area with the most concentrated massage effect, significantly improving heating efficiency. This avoids the need for heating the entire massage head by reducing heating of unnecessary areas. Furthermore, by setting the area of ​​the third surface between 0.4a and 0.6a, the energy waste associated with large-area heating is further reduced while ensuring effective heating. This significantly improves battery life while maintaining a good massage effect. Attached Figure Description

[0037] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0039] An embodiment of this application provides a massager, comprising:

[0040] The housing includes a handle and a first massage head movably connected to the handle, the first massage head including a body and a first massage surface disposed on the body;

[0041] A first protrusion is provided on the first massage surface. The first protrusion separates the first massage surface to form a first surface and a second surface. The side of the first protrusion facing away from the first massage surface has a third surface.

[0042] A first heating film covers the third surface;

[0043] Wherein, the direction from the third surface to the first massage surface is defined as the first direction, the projected area of ​​the first massage surface along the first direction is a, and the projected areas of the first surface, the second surface and the third surface along the first direction are m1, m2 and m3 respectively, satisfying 0.2a≤m1≤0.3a, 0.2a≤m2≤0.3a and 0.4a≤m3≤0.6 respectively.

[0044] The massager described above features protrusions on the massage surface. These protrusions are the first points of contact during massage, resulting in the best massage effect. By covering only the third surface—the side where the massage head protrusions contact the user—heat is concentrated in the area with the most concentrated massage effect, significantly improving heating efficiency. This avoids the need for heating the entire massage head by reducing heating of unnecessary areas. Furthermore, by setting the area of ​​the third surface between 0.4a and 0.6a, the energy waste associated with large-area heating is further reduced while ensuring effective heating. This significantly improves battery life while maintaining a good massage effect.

[0045] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0046] Please see Figures 1-7 An embodiment of this application provides a massager 100, including a housing 10, a first boss 20, and a first heating film 30;

[0047] The housing 10 includes a handle 11 and a first massage head 12 movably connected to the handle 11. The first massage head 12 includes a body 121 and a first massage surface 122 disposed on the body 121.

[0048] A first protrusion 20 is provided on the first massage surface 122. The first protrusion 20 divides the first massage surface 122 to form a first surface 122a and a second surface 122b. The side of the first protrusion 20 facing away from the first massage surface 122 has a third surface 21.

[0049] The first heating film 30 covers the third surface 21.

[0050] Wherein, the direction in which the third surface 21 points to the first massage surface 122 is defined as the first direction, the projected area of ​​the first massage surface 122 along the first direction is a, and the projected areas of the first surface 122a, the second surface 122b and the third surface 21 along the first direction are m1, m2 and m3 respectively, satisfying 0.2a≤m1≤0.3a, 0.2a≤m2≤0.3a and 0.4a≤m3≤0.6 respectively.

[0051] Specifically, the housing 10 is the outer frame of the massager, providing support and protection for the internal components. The housing 10 is designed to ensure both strength and comfort, facilitating user grip and operation. The handle 11 is ergonomically designed to ensure comfort during extended use. The massage head is the part that directly contacts the skin and is primarily responsible for performing massage actions. The first protrusion 20 is a raised portion of the massage surface, and it is the part that most directly contacts the skin during massage. Its function is similar to simulating human fingers or joints, allowing for concentrated pressure for deep massage of specific areas. The third surface 21, opposite to the first massage surface 122, is the most protruding part of the massage head, concentrating pressure and contacting the skin for a more focused and powerful massage effect.

[0052] Furthermore, the heating film is placed on the third surface 21, concentrating the heat on the area where the massage effect is most concentrated. The third surface 21 is usually the area that directly contacts the skin and generates the greatest massage pressure; the heat helps relax muscles and promote blood circulation. By concentrating the heating film on the third surface 21, the traditional practice of covering the entire massage head with a heating film is avoided, reducing energy waste and improving heating efficiency.

[0053] Furthermore, by setting the proportional relationship between m1, m2, and m3, heat is concentrated on the third surface 21 (m3) while unnecessary heating of other areas (first surface 122a and second surface 122b) is avoided. This design effectively utilizes the area of ​​the heating film and optimizes the heating effect. By setting the area (m3) of the third surface 21 within a larger range (0.4a-0.6a), the effectiveness of the heat application area is guaranteed, battery energy consumption is reduced, and the device's battery life is improved. Concentrating heat on the third surface 21 avoids large-area ineffective heating, ensuring that heat can act quickly and effectively on the skin surface during massage. The projected area of ​​m1 + m2 + m3 is equal to the projected area of ​​the massage surface in the same direction.

[0054] The following are practical data for setting the projection area ratio:

[0055]

[0056]

[0057] All data are from experiments conducted under the same power and battery capacity conditions. The heating effect is based on the user's sensation during use. The duration is based on the existing technology where the heating film completely covers the massage head.

[0058] In summary, based on experimental data, setting the m3 content between 40% and 60% balances heating effect and battery life. At this ratio, the massager maintains good heating performance while effectively controlling power consumption and achieving optimal battery life.

[0059] In one specific embodiment, m1 = 0.25a, ​​m2 = 0.25a, ​​and m3 = 0.5a.

[0060] Specifically, when the proportion of m3 is 0.5a, it can better balance the combination of heating and battery life. The larger proportion of m3 ensures that the heat is concentrated in the most effective area, which provides an ideal massage effect while avoiding overheating and power waste.

[0061] In one specific embodiment, the massager further includes a oscillating component 40;

[0062] The swing assembly 40 includes a motor 41 disposed in the handle 11 and an eccentric member 42 disposed on the motor 41. The side of the eccentric member 42 facing away from the motor 41 is disposed on the massage head. The eccentric member 42 is used to drive the swing of the massage head. The first heating film 30 is disposed along the swing direction of the massage head.

[0063] Specifically, the motor 41 is the core component driving the oscillation of the massage head. It converts electrical energy into mechanical energy, providing the necessary power to drive the oscillation of the massage head. The motor 41 is usually located inside the handle 11, which effectively utilizes the space in the handle 11 and reduces the overall size. The motor 41 provides a stable driving force, allowing the massage head to oscillate at a certain frequency, producing a relatively uniform and continuous massage effect. The selection of the motor 41 should take into account power and efficiency to ensure that the massager has sufficient massage intensity and service life. The design of the eccentric component 42 ensures that the massage head has a certain degree of deviation or oscillation amplitude, avoiding the massage head from working in a simple linear vibration mode. Through this oscillation, the massage head can better simulate the movements of hand massage, increasing the comfort and effect of the massage.

[0064] Furthermore, the first heating film 30, located on the massage head, is the key heating element of the massager. Current passes through the heating film to generate heat. The heating film is positioned along the oscillation direction of the massage head, i.e., parallel to its oscillation trajectory. This design ensures uniform heating during the massage, preventing some areas from becoming too hot or too cold, thus improving comfort and safety. By aligning with the oscillation direction of the massage head, the heating film can continuously and evenly provide heat to the massaged area, ensuring consistent massage results. During the massage, heat will not become excessively concentrated or unevenly distributed due to the oscillation of the massage head.

[0065] In one specific embodiment, the first heating film 30 includes a first heating part 31, a second heating part 32, and a third heating part 33 arranged sequentially;

[0066] The second heating element 32 covers the third surface 21. The first heating element 31 and the third heating element 33 are both disposed on the main body 121. The main body 121 has a through groove 121a. The third heating element 33 extends into the through groove 121a to fix the first heating film 30.

[0067] Specifically, during the massage process, the third surface 21 is the key massage surface. Heating its temperature can maximize massage comfort and enhance the user experience. Since the third surface 21 usually covers the oscillation path of the massage head, it needs a stable heating area to avoid uneven massage effects caused by localized low temperatures.

[0068] Furthermore, the three heating elements, the first heating element 31 and the third heating element 33, are located at opposite ends of the second heating element 32, ensuring sufficient heat support from the highest to the lowest point when the massage head oscillates. This arrangement allows the first heating element 31 and the third heating element 33 to cover the highest and lowest points of the massage head during oscillation, respectively. This arrangement helps to provide a uniform heating effect during massage head oscillation and avoids temperature differences caused by localized low temperatures. For example, when the massage head reaches its highest or lowest point during oscillation, the first heating element 31 and the third heating element 33 ensure that these two positions are continuously heated, thereby preventing uneven temperature distribution in the massage area and ensuring the massage effect and user comfort.

[0069] Furthermore, the through groove 121a design helps to precisely position the third heating element 33, thereby helping to secure the overall heating film and preventing it from loosening or falling off during operation due to vibration or friction. At the same time, the presence of the through groove 121a allows the third heating element 33 to connect better with the main body 121 structure of the massage head, thus improving the overall stability and durability of use.

[0070] In one specific embodiment, the handle 11 further includes two parallel limiting blocks 111, with a movable groove formed between the two limiting blocks 111, and is located at one end of the handle 11 near the massage head;

[0071] The massager also includes a rotating component 50, which is disposed between the handle 11 and the massage head. The rotating component 50 is fixedly connected to the main body 121 and is disposed in the movable groove, which is used to limit the swing direction of the massage head.

[0072] Specifically, the design of the movable groove ensures that the massage head can swing within a certain angle range under the support of the handle 11, avoiding excessive swing angle that could cause discomfort or damage to the mechanical structure. Through the cooperation of the limit block 111, the movable groove restricts the swing range of the massage head, making the massage process more stable and controllable. The rotating component 50 allows the massage head to swing within the limited range of the movable groove, and the effective movement of the massage head is achieved through the rotation of the rotating component 50. The rotating component 50, through its fixed connection with the main body 121, ensures that the massage head remains stable and does not deviate from its designed trajectory.

[0073] In one specific embodiment, the first massage head 12 further includes a fixing block 123, and a plurality of fixing blocks 123 are disposed on the inner surface of the massage head to form a fixing groove 123a;

[0074] The massager also includes a vibration component 60, which includes a motor 61 disposed in the massage head and an eccentric block 62 disposed on the motor 61. The motor 61 is disposed in the fixing groove 123a, and the eccentric block 62 is disposed at one end of the motor 61 near the first massage surface 122 for generating vibration.

[0075] Specifically, the fixing block 123, through the enclosing fixing groove 123a, ensures that the vibration component 60 (including the motor 61 and the eccentric block 62) is stably positioned within the massage head, preventing unstable vibration or noise caused by loosening of the component during vibration. The design of the fixing groove 123a and the fixing block 123 enhances the mechanical stability of the internal vibration system of the massage head, ensuring that the vibration component 60 will not loosen, shift, or experience other structural problems during long-term use, thus improving the reliability of the device. The precise fixing structure ensures that the vibration component 60 will not shift during operation, thereby guaranteeing the uniformity and stability of the vibration effect.

[0076] Furthermore, the motor 61 is the core component of the vibration assembly 60. It converts electrical energy into mechanical energy to drive the eccentric block 62 to rotate. Due to the design of the motor 61, it can provide a stable power source, ensuring that the massage head continuously outputs vibration during use. The eccentric block 62 generates vibration through its eccentric rotation. The position of the eccentric block 62 close to one end of the massage surface allows for better transmission of vibration to the massage surface. When the motor 61 drives the eccentric block 62 to rotate, due to the uneven mass distribution, the eccentric block 62 causes the massage head to vibrate periodically. This vibration, combined with the heating effect of the heating film, stimulates blood circulation to improve skin health, providing assistance for beauty skincare or anti-aging care.

[0077] In one specific embodiment, the fixing blocks 123 on opposite sides of the fixing groove 123a respectively fit against the inner surface of the main body 121, and the fixing blocks 123 and the main body 121 enclose to form the vibration cavity 124.

[0078] Specifically, the fixing block 123 is the part that fits against both sides of the fixing groove 123a. The main function of the fixing block 123 is to help the vibration component 60 be firmly fixed inside the massage head. At the same time, the enclosure of the fixing block 123 effectively limits the range of motion of the vibration component 60, ensuring that the vibration component will not be misaligned or vibrate excessively during operation. The vibration cavity 124 is a cavity structure formed by the fixing block 123 and the fixing groove 123a. The function of this cavity is to provide a stable working space for the vibration component 60. The vibration cavity 124 helps to guide and enhance the propagation of vibration, so that the vibration can be transmitted more evenly to the massage surface of the massage head, thereby improving the uniformity and depth of the massage effect.

[0079] Furthermore, the vibration cavity provides a closed space to house the vibration assembly 60 (such as the motor 61 and the eccentric block 62). When the motor 61 and the eccentric block 62 operate, they generate heat due to friction, movement, etc. The vibration cavity 124 is separated from the massage surface by a housing 10, and the heat generated in the vibration cavity 124 is conducted to the massage surface through the housing 10. The vibration cavity 124 captures and accumulates heat through its closed structure, thereby reducing heat loss and concentrating the heat transfer to the surrounding massage surface. This design utilizes the useless heat energy generated by the vibration assembly 60 during operation, avoiding heat waste and making the heat useful during the massage process, providing a comfortable heating effect.

[0080] Furthermore, the design of temperature accumulation and heat transfer within the vibration chamber 124 functions as a heat recovery system. This allows the massager's heating effect to not only rely on the operation of the heating film itself but also to be enhanced through the operation and heat accumulation of the vibration component 60. The heating film itself typically generates heat through electric current. The heating film is not only an actively heated component but also utilizes passive heat sources within the vibration chamber 124 (i.e., waste heat from the motor 61 and eccentric block 62) to further improve the heating effect, thereby saving energy and improving overall thermal efficiency.

[0081] In one specific embodiment, the massager further includes a second massage head (not shown in the figure), one end of which is disposed on the handle 11, and the other end is inclined outward;

[0082] The massager also includes a second heating film (not shown in the figure), a second massage surface of the second massage head (not shown in the figure), and the second heating film covers the second massage surface along the length of the massage head.

[0083] Specifically, one end of the second massage head is mounted on the handle 11, while the other end is tilted outwards. This design allows the second massage head to adapt to different massage angles, enhancing the massager's versatility. The tilted angle allows for better and more effective massage of hard-to-reach areas such as the neck, shoulders, or back, ensuring comfort and comprehensiveness during the massage process. This design also makes the massager more versatile, meeting the needs of different users, especially those requiring multi-angle massage or massage of specific areas.

[0084] Furthermore, the second heating film covers the second massage surface along the length of the second massage head. This means that the heating area on the second massage head will generate a uniform heat effect with the movement of the massage head, providing heating through the heating film and further enhancing the massage effect. By setting the heating film along the length of the massage head, it is ensured that the heating area covers a wider massage area, thereby providing uniform heat distribution and avoiding problems such as local overheating or uneven heating.

[0085] In one specific embodiment, the massager further includes a second protrusion (not shown) disposed on the second massage surface, the side of the second protrusion facing away from the second massage surface being disposed on a fourth surface (not shown), and the second heating film covering the fourth surface.

[0086] Specifically, the second protrusion is disposed on the surface of the second massage surface. More specifically, a fourth surface is provided on the side of the second protrusion facing away from the second massage surface, and the second heating film covers the fourth surface. The design of the second protrusion not only changes the surface structure of the massage head, but also further optimizes the massage effect and heat distribution.

[0087] Furthermore, by setting a heating film on the fourth surface of the second protrusion, the problem of an excessively large or unevenly distributed heating film is avoided, ensuring that heat is concentrated in the area requiring heating and preventing energy waste. This design maximizes effective heat transfer by reducing unnecessary heating areas, thereby reducing power consumption. The combination of the fourth surface and the structure of the second protrusion allows the heating effect to be precisely and directionally applied to the massage area, thus avoiding excessive heat waste in traditional massagers and improving energy efficiency. The second protrusion has a similar effect to the first protrusion 20, also designed to ensure both heating effectiveness and power consumption.

[0088] In one specific embodiment, the massager further includes a control mechanism 90, which includes a power supply component 91 and a control component 92 electrically connected to the power supply component 91;

[0089] The power supply component 91 includes a power supply 911 and a fixing base 912. The fixing base 912 is located at the bottom of the handle 11. The power supply 911 is fixedly connected to the fixing base 912 and electrically connected to the first heating film 30 for supplying power to the first heating film 30.

[0090] The control component 92 includes a control panel 921 and a stepless adjustment device 922 connected to the control panel 921 for data communication. The control panel 921 is disposed on the fixed base, and the stepless adjustment device 922 is disposed on the side of the fixed base away from the control panel 921, for adjusting the power of the first heating film 30.

[0091] Specifically, the power supply 911 provides stable power, serving as the power source for the entire system and ensuring the massager operates effectively, especially for powering the heating film (such as the first heating film 30). The mounting base 912, located at the bottom of the handle 11, provides physical support for the power supply 911 and securely connects it to other components. Its design ensures the stability and safety of the power supply 911 during use. It ensures a stable connection between the power supply 911 and the first heating film 30, providing stable and efficient heating capabilities, thus improving the massager's heating performance and continuous usage time. The mounting base 912 effectively protects the power supply 911 and the circuitry, preventing poor connections due to vibration or swaying.

[0092] Furthermore, the control panel 921, located on the fixed base, serves as the user interface for interacting with the massager. It typically includes buttons, a display screen, or a touchscreen, used to show information such as temperature and power settings. Users can adjust the massager's operating mode through the control panel 921. The stepless adjustment device 922, located on the side of the fixed base opposite the control panel 921, primarily functions to precisely adjust the power of the heating film, altering the heating effect. The stepless adjustment design allows users to seamlessly adjust the heating temperature or intensity as needed, providing a personalized massage experience.

[0093] Furthermore, the stepless adjustment device 922 allows users to finely adjust the heating intensity, avoiding the limitations of preset levels in traditional massagers and providing greater flexibility and comfort. The stepless adjustment device 922 can also adjust the vibration frequency of the massage head; multiple functions can be adjusted via the control panel 921.

[0094] Furthermore, the control component 92 is controlled by a program that detects a long press of the switch. When a valid long press is detected, the system enters the working mode and simultaneously controls the output of the motor 61 via PWM. In the corresponding working mode, the program controls the heating device and achieves constant temperature output through NTC temperature detection. When a short press of the switch is detected, the system cycles through different modes, switching the speed and rotation method of the motor 61 accordingly. A long press of the switch enters the power-off mode from the working mode, and the program saves the corresponding working mode. In each working mode, the motor 61 can be continuously variable in speed via an encoder.

[0095] The continuously variable transmission (CVT) controls the motor 61 by outputting a PWM (PWM is a technique that modulates the width of a series of pulses to obtain the desired waveform) signal. The program detects the encoder input, determines the encoder's rotation direction, and adjusts the duty cycle (the signal consists of high and low levels, and the output of the motor 61 is controlled by adjusting the time ratio of the high level) according to the rotation direction. Based on the detected encoder input, the program achieves continuously variable transmission control of the motor 61 by adjusting the output duty cycle.

[0096] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
