Description

Technical Field

[0001] This application belongs to the field of massager technology, specifically relating to an electric massager and an electric massager assembly. Background Technology

[0002] Existing electric massagers typically use buttons to adjust massage intensity and frequency, with the intensity level changing sequentially based on the number of button presses. Since individual sensations vary, a large number of intensity levels are required for more precise control. Users must manually switch between the lowest and highest intensity levels to find a comfortable setting, which is inconvenient and involves numerous operations. Some existing electric massagers use multiple buttons corresponding to specific intensity levels, reducing the number of switching operations, but this design negatively impacts the product's aesthetics.

[0003] Some electric massagers have pressure sensors on the massage heads that sense the pressure applied to the skin to adjust the massage intensity. This method requires applying pressure to the skin surface, and the massage intensity is related to the skin pressure, affecting the massage comfort experience.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0005] Therefore, this application aims to solve the technical problems of inconvenient massage intensity adjustment and low comfort in the prior art.

[0006] To solve the above-mentioned technical problems, this application provides an electric massager, comprising:

[0007] Main body;

[0008] A massage head, used for massaging the skin, is located at one end of the main body.

[0010] A pressure sensor is disposed inside the main body for sensing external pressure;

[0011] The controller is located in the main body and is electrically connected to the motor;

[0012] A pressure sensing area is formed on the peripheral surface of the main body. The pressure sensor is disposed against the inner surface of the pressure sensing area and is used to sense the pressure applied to the pressure sensing area. The controller is electrically connected to the pressure sensor and is used to control the speed of the motor to adjust the massage frequency of the massage head according to the pressure sensing signal of the pressure sensor.

[0013] In one embodiment, the number of pressure sensing areas is two, and the peripheral surface of the main body includes two opposing sides, with the two pressure sensing areas respectively formed on the opposing side surfaces.

[0014] In one embodiment, the main body has a split surface, and the direction perpendicular to the split surface is the width direction of the main body.

[0019] In one embodiment, the electric massager further includes a transmission link for converting the rotational motion of the motor into reciprocating motion, one end of the transmission link being connected to the motor and the other end being connected to the massage head to drive a change in the volume of the negative pressure chamber.

[0020] In one embodiment, there are two pressure sensors, which are respectively disposed abutting the inner surfaces of the two pressure sensing areas. The controller is used to control the speed of the motor based on the larger value of the pressure sensing signals from the two pressure sensing areas.

[0021] In one embodiment, the electric massager further includes a cover for shielding the massage head, the cover being detachably connected to the main body.

[0022] In one embodiment, one of a magnet and a magnetic attractor is fixedly disposed inside the cover, and the other of a magnet and a magnetic attractor is disposed at a corresponding position on the main body. When the cover is closed on the main body, the magnet and the magnetic attractor are attracted together.

[0023] In addition, this application also provides a pressure-applying operating accessory for applying pressure to the pressure sensing area of ​​an electric massager, including:

[0024] A flexible sleeve is suitable for being fitted onto the main body of the electric massager. The flexible sleeve includes a pressure-sensitive hollow area that is hollowed out. When the flexible sleeve is fitted onto the main body, the pressure-sensitive area is exposed through the pressure-sensitive hollow area.

[0025] A trigger arm is disposed on the outside of the flexible sleeve. The trigger arm includes a connecting end and a trigger end opposite to the connecting end. The connecting end is connected to the flexible sleeve, and the trigger end extends to the outside of the pressure-sensitive hollow area. The trigger end includes an inner surface facing the pressure-sensitive hollow area and an outer surface opposite to the inner surface. The outer surface is used for pressing by the operator, and the inner surface is used to contact the pressure-sensing area to apply pressure.

[0026] The trigger arm includes a deformed state after being pressed and a free state after the pressure is released. When the pressure is released, the trigger arm automatically returns to the free state.

[0027] In one embodiment, the hardness of the trigger arm is greater than the hardness of the flexible sleeve, and in the free state, there is a gap between the inner surface of the trigger end and the pressure sensing area.

[0028] In one embodiment, the flexible sleeve is provided with a connecting portion, and the connecting end of the trigger arm is provided with a positioning portion, wherein the positioning portion and the connecting portion are detachably connected.

[0030] In one embodiment, the shape of the end face of the connecting post matches the shape of the surface adjacent to the root of the positioning part, and when the connecting end is connected to the flexible sleeve, the end face of the connecting post fits against the surface adjacent to the root of the positioning part.

[0032] In one embodiment, the connecting end of one of the trigger arms is directly opposite the trigger end of the other trigger arm.

[0033] In one embodiment, the inner surface of the trigger end facing the pressure-sensitive hollow area is configured as a curved surface protruding toward one side of the pressure-sensitive hollow area.

This configuration allows the operator to apply pressure from the side of the main body, making operation convenient and comfortable. The controller adjusts the motor speed according to the sensed pressure to adjust the massage frequency of the massage head, resulting in more sensitive frequency adjustment and reducing the impact of pressure applied to the pressure sensing area on the massage pressure of the massage head, thus ensuring massage comfort.

[0050] Example 1

[0051] This embodiment provides an electric massager 100 for contacting the skin surface to perform massage. Figure 1 This is a three-dimensional structural diagram of the electric massager provided in the embodiments of this application. Figure 2 for Figure 1 The diagram shown is an exploded view of the electric massager. Figure 3 for Figure 2 The diagram shown is an exploded view of the electric massager from another perspective. Figure 4 This is a structural schematic diagram of the electric massager provided in the embodiment of this application, viewed along its mid-section. Please refer to... Figures 1 to 4 The electric massager 100 includes a main body 10, a massage head 30, a motor 40, a pressure sensor, and a controller 60 disposed within the main body 10.

[0052] The main body 10 is used by the user to massage the skin and to support and house functional components. These functional components mainly include a motor 40, a pressure sensor (not shown), and a controller 60. An operating area is formed on the outer surface of the main body 10, through which the user controls the contact between the main body 10 and the skin. The pressure sensor is disposed against the inner surface of the operating area to sense the pressure applied to the operating area. The controller 60 is connected to both the pressure sensor and the motor 40, and controls the rotational speed of the motor 40 based on the pressure signal from the pressure sensor to adjust the massage frequency of the massage head 30. A battery is also housed inside the main body 10 to power the motor. Preferably, the battery is a rechargeable battery.

[0053] The operating area of ​​the main body 10 is also equipped with a control switch 11, which is used to control the start and stop of the electric massager 100. Specifically, when the controller 60 receives a trigger signal from the control switch 11, it controls the motor 40 to start running. Preferably, the controller 60 controls the starting speed of the motor 40 to be the minimum operating speed of the motor 40 according to the trigger signal from the control switch 11.

[0054] A massage head 30, used to contact the skin for massaging, is located at one end of the main body 10. For ease of explanation, the end where the massage head 30 is located is defined as the front end of the main body 10, and the opposite end as the rear end. The direction from the "front end" to the "rear end" is defined as the height direction of the main body 10, and the main body 10 has a center line parallel to the height direction. The peripheral surface of the main body 10 surrounds the aforementioned center line, and the operating area is formed on the peripheral surface.

[0055] Please combine Figure 2 and Figure 3 As shown, the operating area of ​​the main body 10 has pressure sensing areas (14, 16). Pressure sensors are disposed against the inner surfaces of the pressure sensing areas (14, 16) to sense the pressure applied to them. In other words, the pressure sensing areas are formed by the peripheral surface of the main body 10 and are located within the operating area for user convenience. In this embodiment, there are two pressure sensing areas (14, 16), namely a first pressure sensing area 14 and a second pressure sensing area 16. The peripheral surface of the main body 10 is annular, including two opposing sides, and the first pressure sensing area 14 and the second pressure sensing area 16 are formed on opposite side surfaces.

[0056] It should be noted that "opposite sides" refers to two surfaces that are roughly the same shape and face each other. The two pressure-sensing areas are formed on opposite sides, which means that the two sides on which the two pressure-sensing areas are located are opposite, not that the two pressure-sensing areas are directly opposite each other.

[0057] In another embodiment, only one pressure sensing area may be provided. Please refer to [reference needed]. Figure 1 and Figure 2 The controller 60 can adjust the motor rotation speed to regulate the massage frequency based on the pressure applied on one side, using either a first pressure sensing area 14 or a second pressure sensing area 16. In other embodiments, multiple pressure sensing areas can be provided, such as three, four, or more. These multiple pressure sensing areas are arranged on the peripheral surface of the main body 10. Each pressure sensing area is equipped with a corresponding pressure sensor to sense the pressure applied to it. The controller adjusts the motor speed based on the operating pressure of the multiple pressure sensors.

[0058] The electric massager provided in this embodiment is for massaging delicate skin. For example, this electric massager can be used for soothing massage of the skin around the eyes and jawline, and can also be used for acupressure massage, such as soothing massage of the temples. This electric massager can also be used for massaging other parts of the body, but this application does not limit its use. The electric massager of this application is mainly designed for massaging delicate skin, with a weak vibration amplitude within 5mm. Specifically, the amplitude of the electric massager is 2mm-3mm.

[0059] To reduce the impact of the electric massager's own vibration on the pressure application, in one embodiment, the sensitivity of the pressure sensor is set to be less than the pressure change caused by its own vibration during operation. Therefore, the vibration of the electric massager will not significantly cause changes in the pressure sensor's measured value, allowing the electric massager to adjust its vibration frequency according to the pressure applied by the user. In another embodiment, the controller 60 is configured to only execute the control logic for adjusting the massage frequency based on the operating pressure if the pressure change detected by the pressure sensor exceeds a preset floating threshold. That is, when the pressure change detected by the pressure sensor is less than the preset floating threshold, the controller 60 does not perform frequency adjustment control, and the massage frequency of the electric massager remains unchanged. Thus, by using a preset floating threshold to shield the pressure sensor's measured value changes caused by the electric massager's own vibration, the purpose of adjusting the massage frequency according to the operator's applied pressure can be achieved.

[0060] The electric massager provided in this application has a massage head located at one end of the main body. A pressure sensing area is formed on the peripheral surface of the main body, and a pressure sensor is disposed against the inner surface of the pressure sensing area to sense the pressure applied to it. There are two pressure sensing areas, formed on opposite sides of the main body. This arrangement allows the operator to apply pressure from both sides of the main body, making operation convenient and comfortable. Both sides of the main body can sense the pressure level, allowing the controller to adjust the motor speed and massage frequency of the massage head based on the sensed pressure. This results in more sensitive frequency adjustment and reduces the impact of pressure applied from the pressure sensing area on the massage head's pressure, ensuring massage comfort.

[0061] The main body is roughly symmetrical and has a mid-section. Figure 4 The image shown is a cross-sectional view of the main body through the bisecting plane. (Combined with...) Figure 1 and Figure 4 The aforementioned dividing surface of the main body 10 is parallel to the height direction and approximately bisects the massage head 30. Based on the above definition of the height direction, Figure 4 The top and bottom of the drawing represent the height of the electric massager 100, and the direction perpendicular to the aforementioned dividing plane represents the width of the main body 10. Figure 4 The left-right direction in the drawing represents the length direction of the main body 10. In this embodiment, the width of the main body 10 is smaller than its height and length. The first pressure sensing area 14 and the second pressure sensing area 16 are respectively disposed on opposite sides along the width direction. Thus, the thickness of the main body between the two pressure sensing areas is minimized, facilitating pressure application.

[0062] In practical applications, the pressure applied to opposite sides is often not directly opposite each other, and each pressure sensing area is independent. To accurately calibrate the relationship between the pressure applied by the operator and the massage frequency, in one embodiment, the projections of the first pressure sensing area 14 and the second pressure sensing area 16 on the dividing plane are offset from each other. That is, the two pressure sensing areas are not directly opposite each other, and the pressure sensing areas sense the pressure applied at corresponding positions on different sides, thereby accurately and sensitively capturing the operator's intention to adjust the massage frequency.

[0063] In a specific embodiment, the massage head 30 includes a massage opening 32 for conforming to the skin, which is used to perform massage movements. In actual use, the axis of the massage opening 32 is typically perpendicular to the skin contact surface. In this embodiment, the axis of the massage opening 32 is parallel to the height direction of the main body 10, which facilitates the operator's control over the contact between the massage opening and the skin.

[0064] To suppress the influence of the pressure sensed by the pressure sensing area on the contact pressure between the massage port and the skin, thus ensuring a comfortable massage experience, in a specific embodiment, the pressure sensor is configured such that the direction of the sensed pressure is approximately perpendicular to the axis of the massage port 32. The pressure component sensed by the pressure sensor and the pressure component of the massage port on the skin do not affect each other, thereby facilitating user control of skin pressure and massage frequency.

[0065] In specific embodiments, please refer to Figure 3 and Figure 4 The massage head 30 has a flexible structure and forms a negative pressure chamber 34. The opening of the negative pressure chamber 34 forms a massage port 32. The motor 40 is connected to the massage head 30 to drive the massage head 30 to reciprocate, causing the volume of the negative pressure chamber 34 to change, thereby generating negative pressure at the massage port 32. Specifically, the electric massager 100 also includes a transmission link 50. One end of the transmission link 50 is connected to the output shaft of the motor 40, and the other end is connected to the massage head 30, converting the rotational motion of the motor 40 into the reciprocating deformation motion of the massage head 30. During the reciprocating deformation motion, the volume of the negative pressure chamber 34 is frequently changed, thereby forming negative pressure at the massage port 32, and using the negative pressure to massage the skin surface.

[0066] In a specific embodiment, two pressure sensors are used: a first pressure sensor and a second pressure sensor, which are respectively disposed abutted against the inner surfaces of the first pressure sensing area 14 and the second pressure sensing area 16. The first pressure sensor is disposed abutted against the first pressure sensing area 14, and the second pressure sensor is disposed abutted against the second pressure sensing area 16. The pressure sensing signal from the first pressure sensor is a first pressure signal, and the pressure sensing signal from the second pressure sensor is a second pressure signal. The controller 60 controls the rotational speed of the motor 40 based on the larger value of the pressure sensing signals from the two pressure sensing areas. That is, if the first pressure signal is greater than the second pressure signal, the controller 60 controls the rotational speed of the motor 40 based on the first pressure signal; if the first pressure signal is less than the second pressure signal, the controller 60 controls the rotational speed of the motor 40 based on the second pressure signal. A larger pressure signal value corresponds to a larger rotational speed of the motor 40. This improves the pressure response sensitivity of the electric massager and enhances the massage experience.

[0067] In a specific embodiment, the electric massager 100 also includes a cover 20 for covering the massage head 30, and the cover 20 is detachably connected to the main body 10. When the user needs to use the electric massager 100, the cover 20 is removed to expose the massage head 30, thereby massaging the skin. After use, the cover 20 is installed on the main body 10, and the massage head 30 is covered and protected within the cover 20, achieving dust prevention and protection.

[0068] Furthermore, please combine Figure 4 and 5A magnet 21 is fixedly installed inside the cover 20, and a magnetic suction component 11 is installed at a corresponding position on the main body 10. When the cover 20 is closed on the main body 10, the magnet 21 and the magnetic suction component 11 attract each other, thereby achieving a reliable connection between the cover 20 and the main body 10. Specifically, the magnetic suction component 11 can be an iron block or an alloy structure containing iron, nickel, and cobalt. Of course, the magnetic suction component can also be installed on the cover 20, and correspondingly, a magnet is installed on the main body 10; there is no limitation here.

[0069] The main body 10 of the electric massager 100 is also provided with an auxiliary massage head 15, which is used to rest against the skin surface and massage the skin using the vibration of the main body 10 itself. It can also help position the electric massager 100. Specifically, the auxiliary massage head 15 is located at the same end as the massage head 30 and is arranged side by side with the massage head 30. The auxiliary massage head 15 is made of soft rubber and has an overall shape of a cone with a rounded top.

[0070] The electric massager provided in this embodiment has pressure sensing areas located on opposite sides of the main body. The motor speed can be adjusted by applying pressure from both sides to regulate the massage frequency. The pressure adjustment is flexible and convenient, and the massage comfort is high.

[0071] Example 2

[0072] This embodiment provides a pressure-applying accessory for mounting on the main body of an electric massager to assist in applying pressure from the massager's pressure sensor. This embodiment applies the pressure-applying accessory to... Figure 1 The electric massager 100 shown is for illustrative purposes only and should not be construed as a limitation of this application.

[0073] In this implementation scenario, please combine Figure 1 , 2 As shown in Figure 6, the electric massager 100 includes a main body 10, and a pressure-sensing area is formed on the outer surface of the main body 10. A pressure-applying operation attachment 80 is connected to the main body 20 for applying pressure to the pressure-sensing area. For details, please refer to... Figure 4 The main body 10 includes a massage head 30 and a motor 40 that is connected to the massage head 30 for driving the massage head to move in order to massage the skin in contact with it.

[0074] In this embodiment, the pressure application accessory 80 is mounted on the main body 10 of the electric massager 100 and used in conjunction with the main body 10. Of course, the electric massager 100 can also be used independently. When the electric massager 100 is used independently, such as... Figure 3 As shown, the operator can directly press the pressure sensing areas (14, 16) to adjust the massage frequency of the electric massager. When the pressure application attachment 80 is engaged with the main body 10, as... Figure 6As shown, the operator applies pressure to the pressure sensing areas (14, 16) by operating the pressure application accessory 80. The operator can choose whether to use the pressure application accessory 80 based on specific operating comfort and personal preference.

[0075] Please see Figure 7 , Figure 8 The pressure application accessory 80 includes a flexible sleeve 11 and a trigger arm 12.

[0076] The flexible sleeve 81 is a flexible structure suitable for fitting onto the main body 10 of the electric massager. The flexible sleeve 81 includes a perforated pressure-sensitive perforated area 810. When the flexible sleeve 81 is fitted onto the main body 10, the pressure-sensing areas (14, 16) of the main body 10 are exposed through the pressure-sensing perforated area 810. Specifically, the pressure-sensing perforated areas 810 correspond one-to-one with the pressure-sensing areas, and there are two pressure-sensing perforated areas 810, with the first pressure-sensing area 14 and the second pressure-sensing area 16 corresponding to the two pressure-sensing perforated areas 810 respectively. The flexible sleeve 81 is made of silicone or flexible plastic.

[0077] It should be noted that the aforementioned "cutout setting" is understood as creating a notch in a specific area in the center of the surface of the flexible sleeve, thereby facilitating the direct exposure of an object located on the other side of the flexible sleeve surface. The pressure-sensitive cutout area 810 is a cutout area corresponding to the pressure sensing areas (14, 16), used to expose the pressure sensing areas (14, 16) of the main body 10. The flexible sleeve 81 can also have cutout areas for other purposes, and the cutout areas can be named accordingly depending on their function.

[0078] The trigger arm 82 is connected to the flexible sleeve 81 and located on the outside of the flexible sleeve 81, for applying pressure to the pressure sensing areas (14, 16) of the electric massager 100. For details, please refer to [link to relevant documentation]. Figure 7 The trigger arm 82 includes a connecting end 821 and a trigger end 822 opposite to the connecting end 821. The connecting end 821 is connected to the flexible sleeve 81, and the trigger end 822 extends to the outside of the pressure-sensitive hollow area 810 for applying pressure to the pressure-sensing area. Please refer to section 7 and... Figure 9As shown, the trigger end 822 includes an inner surface 8221 facing the pressure-sensitive hollow area 810 and an outer surface 8223 opposite to the inner surface. The outer surface 8223 is used for pressing by the operator, and the inner surface 8221 is used to contact the pressure sensing area (14, 16) of the main body 10 to apply pressure. The trigger arm 82 is a deformable structure that deforms under external force. The trigger arm 82 includes a deformed state after being pressed and a free state after the pressure is released. When the pressure is released, the trigger arm 82 automatically returns to the free state. Thus, when the operator no longer applies pressure to the trigger arm 82, the trigger arm 82 automatically returns to the free state, and the sensing pressure of the pressure sensing area returns to its initial state. Normally, in the free state, the pressure applied to the pressure sensing area is zero.

[0079] In this embodiment, the trigger arm 82 extends longitudinally, with the connecting end 821 located at one end along its length and the trigger end 822 located at the other end along its length. When the trigger arm 82 is mounted on the flexible sleeve 81, which is fitted onto the main body 10, the connecting end 821 is fixed relative to the main body 10, and the trigger end 822 is cantilevered with the connecting end 821 as a fulcrum. When the trigger end 822 is pressed by an external force, it deforms to generate a displacement relative to the fulcrum that approaches the pressure sensing area (14, 16). This displacement is used to trigger the pressure sensing area. In other words, the operator applies pressure to the trigger end 822, which in turn applies pressure to the pressure sensing area, rather than directly triggering the pressure sensing area.

[0080] The pressure application accessory provided in this application is used to apply pressure to the pressure sensing area of ​​an electric massager. The flexible sleeve is hollowed out to form a pressure-sensitive hollow area corresponding to the pressure sensing area of ​​the main body. One end of the trigger arm is connected to the flexible sleeve, and the other end extends to the outside of the pressure-sensitive hollow area as an operating end, which is used by the user to apply pressure to the pressure sensing area through the operating end. The trigger arm increases the operating distance. When it is inconvenient to directly trigger the pressure sensing area, the user can choose to use the pressure application accessory, thereby making the pressure application operation more convenient in this case and improving the usability of the electric massager.

[0081] Specifically, the hardness of the trigger arm 82 is greater than that of the flexible sleeve 81. The flexible sleeve 81 has lower hardness and is more flexible, making it easier to fit onto the main body 10 of the electric massager. The trigger arm 82 is made of a harder material, which facilitates its automatic return to a free state after the external force is removed, improving its durability. In the free state, there is a gap between the inner surface 8221 of the trigger end 822 and the pressure sensing area (14, 16), ensuring that the pressure in the pressure sensing area is zero when the trigger arm 82 is not operated. Preferably, the trigger arm 82 is made of plastic, and the flexible sleeve 81 is made of rubber.

[0082] For easy installation of the pressure application attachments on the main body, please refer to the specific embodiment. Figure 8 and Figure 9 The flexible sleeve 81 is provided with a connecting part 812, and the connecting end 821 of the trigger arm 82 is provided with a positioning part 823. The positioning part 823 and the connecting part 812 are detachably connected. When it is necessary to install the pressure application operation accessory, the flexible sleeve 81 can be first put on the main body 10. Because the flexible sleeve is soft and easily deformable, it is convenient to put on and adjust its position. After the flexible sleeve 81 is installed, the trigger arm 82 is then installed on the connecting part 812 of the flexible sleeve 81, making the installation of the pressure application operation accessory convenient.

[0083] Specifically, the connecting part 812 is constructed as a connecting post, with a hollow interior forming a insertion hole 813. The outer contour of the positioning part 823 matches the shape of the insertion hole 813, and the positioning part 823 is adapted to be inserted into the insertion hole 813 to position the trigger arm 82. More specifically, the positioning part 823 and the insertion hole 813 are interference-fitted. When the positioning part 823 is inserted into the insertion hole 813, the connecting part 812 tightly surrounds and hugs the positioning part 823, and the positioning part 823 and the connecting part 812 are anti-rotationally connected, that is, the positioning part 823 cannot rotate relative to the connecting part 812, thereby positioning the trigger arm 82. Preferably, the cross-section of the connecting part 812 is elliptical, and the insertion hole 113 and the positioning part are also similarly elliptical in shape.

[0084] The trigger arm 82 is connected to the connecting part 812 via the positioning part 823. After the connecting part 812 and the positioning part 823 are connected, the connecting part 812 serves as the positioning fulcrum for the trigger arm 82. The compression deformation and recovery shape of the trigger arm 82 are both supported by the positioning fulcrum. To improve the reliability and stability of the trigger arm 82 support, the shape of the end face of the connecting part 812 matches the shape of the surface adjacent to the root of the positioning part 823. When the connecting end 821 is connected to the flexible sleeve 81, the end face of the connecting part 812 fits against the surface adjacent to the root of the positioning part 823. In this way, the end face of the connecting part acts to support and position the trigger arm, ensuring the reliable reset of the trigger arm.

[0085] In a specific implementation scenario, referring to the content of the first embodiment, there are two pressure sensing areas (14, 16), namely a first pressure sensing area 14 and a second pressure sensing area 16, which are respectively disposed on opposite sides of the main body 20. Correspondingly, there are two trigger arms 82, which are disposed opposite to each other on both sides of the flexible sleeve 81, and are used to trigger the two pressure sensing areas respectively. Pressure sensors are disposed on the first pressure sensing area 14 and the second pressure sensing area 16 to detect the pressure applied to the first pressure sensing area 14 and the second pressure sensing area 16.

[0086] Specifically, the connecting end 821 of one trigger arm 82 is directly opposite the trigger end 822 of the other trigger arm 82. That is, the trigger ends 822 of the two trigger arms 82 are not directly opposite, and the connecting ends 821 of the two trigger arms 82 are also not directly opposite. Thus, when force is applied, the position of the applied force is also not directly opposite, which ensures the sensing of force applied to different positions on both sides and improves the sensitivity of the electric massager to pressure application.

[0087] For ease of pressure application, in one embodiment, please refer to... Figure 7 and Figure 9 The inner surface 8221 of the trigger end 822 facing the pressure-sensitive hollow area 810 is constructed as a curved surface protruding towards one side of the pressure-sensitive hollow area 810. Specifically, this curved surface is roughly circular, with the protrusion height gradually increasing from the outer periphery to the center. When an external force is applied to the trigger end 822, the greater the applied pressure, the larger the contact area between the inner surface 8221 and the pressure-sensing area; conversely, the smaller the applied pressure, the smaller the contact area between the inner surface 8221 and the pressure-sensing area. The configuration of the trigger end 822 can make the triggering of the pressure-sensing area more uniform and stable, improving the accuracy of pressure sensing.

[0088] In the specific embodiments, please refer to the following: Figure 8 The flexible sleeve 81 also includes a button cutout area 814 for exposing the buttons on the main body. Two button cutout areas 814 are located on opposite sides of the flexible sleeve 81. Specifically, the main body 10 includes a control switch 11, which is exposed outside the flexible sleeve 81 through the button cutout area 814 and is used for starting and stopping the electric massager 100.

[0089] The pressure application accessory provided in this embodiment offers a new operating method for electric massagers, compensating for the fact that the operation of the main body alone cannot meet the needs of some operators, and improving the versatility of electric massagers.
