Description

Technical Field

[0001] This utility model relates to the field of massagers, specifically a limb massager. Background Technology

[0002] Existing body massagers, taking leg massagers as an example, generally use airbag pressure to perform massage actions. Specifically, the expansion and contraction of the airbag is controlled by the suction of gas from a pump to perform massage actions on the area covered by the airbag.

[0003] However, for body massagers, the wearing position may vary between different users and during different massage sessions, and different users may have different physical characteristics, which may result in the massager not being able to massage the correct position and thus not achieving a good massage effect. Summary of the Invention

[0004] To address the above problems, this utility model provides a limb massager that can solve the problem that existing limb massagers are difficult to apply force accurately to the target massage location when the user's physical characteristics and wearing position are different.

[0005] To address the aforementioned problems in the prior art, this utility model provides a limb massager, comprising a cylinder, an airbag, a pump, a sensor, and a drive unit. The cylinder is adapted to wrap around and accommodate a limb. The airbag is disposed inside the cylinder, and the pump is connected to the airbag to introduce or expel gas into or out of the airbag, thereby massaging the limb by expanding or contracting the airbag. The sensor is disposed inside the cylinder to detect the shape parameters of the limb. The drive unit is connected to the airbag and can drive the airbag to move along the length of the cylinder. The drive unit is also directly or indirectly connected to the sensor to move the position of the airbag according to the shape parameters detected by the sensor.

[0006] The limb massager provided by the first aspect of this utility model can utilize sensors to detect the shape parameters of the limbs. For example, a leg massager can detect the user's leg shape, thereby making a more accurate judgment on the target massage position. Furthermore, the drive unit can move the airbag position, and then, based on the sensor detection results, move the airbag to the target massage position, accurately applying force to the target massage position. Through the above methods, the limb massager provided by the first aspect of this utility model can accurately apply force to the user's target massage position, avoiding the impact of differences in individual user characteristics or wearing position on the accuracy of the applied force.

[0007] Optionally, the sensor is a Hall sensor or a capacitance sensor. Using pressure sensors such as Hall sensors and capacitance sensors, the reaction force of the user's limbs can be measured as the airbag expands or contracts, thereby measuring the user's limb shape.

[0008] Optionally, multiple sensors are spaced apart along the length of the cylinder. By utilizing multiple sensors, the combined measurement and calculation results can be easily used to infer the user's limb shape, thereby accurately determining the target massage location.

[0009] Optionally, the drive unit includes a flexible track and a walking motor. The flexible track is arranged along the length of the cylinder. One side of the walking motor is fixed to the airbag, and the other side is movably connected to the flexible track. The drive unit, consisting of the flexible track and the walking motor, can accurately deliver the airbag to the target massage position without affecting or minimally affecting the wearing comfort of the limb massager.

[0010] Optionally, the limb massager includes a main body and two cylindrical bodies, which are symmetrically connected to the same side or opposite ends of the main body. The limb massager can be a leg massager or an arm massager. In some embodiments, for a leg massager, the two cylindrical bodies can be symmetrically connected to the same side of the main body, worn as trousers on the user's legs. In other embodiments, for an arm massager, the two cylindrical bodies can be symmetrically connected to opposite ends of the main body, worn as clothing on the user's body and arms.

[0011] Optionally, the pump is located in the main body. Positioning the pump in the main body will not affect, or will minimally affect, the wearing comfort of the limb massager.

[0012] Optionally, it also includes a control panel, settings, and main body. The control panel is communicatively connected to the pump, drive unit, and sensors. The control panel provides the user with controls to operate the massage position, allowing the user to actively adjust the target massage position.

[0013] Optionally, it also includes a power supply module, which is electrically connected to the pump, drive unit, and control panel. The power supply module can be an external power source or a battery built into the limb massager. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] <100 Body Massagers>

[0019] refer to Figure 1 In some embodiments of this utility model, a limb massager 100 is provided. The limb massager 100 is shaped like a pair of pants and can be worn on the user's legs to massage them. In other embodiments, the limb massager 100 may also be a massager for massaging only specific areas of the legs, such as a device that massages only the thighs, or only the calves, or both the calves and feet. This utility model does not limit this to any particular type. In still other embodiments of this utility model, the limb massager 100 may also be a device for massaging the user's arms, or a device that can simultaneously massage the user's arms and hands, or simultaneously massage the user's arms and shoulders.

[0020] In this embodiment, the limb massager 100 includes a main body 102 and a cylindrical body 104. The main body 102 is suitable for wearing on the user's lower abdomen and buttocks, and the cylindrical body 104 is suitable for wearing on the user's legs, specifically in a way that wraps around and accommodates the user's legs. The limb massager 100 provided in this embodiment is mainly used for massaging the legs. Accordingly, the limb massager 100 is provided with multiple airbags 106 in the leg area, and a pump 108 is provided inside the main body 102. The pump 108 and the multiple airbags 106 are in communication with airflow, and can synchronously or independently inflate or deflate each airbag 106. As the pump 108 inflates or deflates, the airbags 106 can expand or contract accordingly. The outer end of the expanded airbag 106 can apply force to the leg, and as the airbag 106 contracts, the force on the leg can be released. The expansion and contraction of the airbags 106 can be coordinated to massage the legs. The pump 108 is located in the main body 102, which will not affect or will have little effect on the normal operation of the massage action of the cylinder 104, and provides a good wearing comfort.

[0021] In other embodiments, other massage action units besides the airbag 106 can also be provided, such as units that perform percussion, vibration, kneading, etc., to enrich the massage actions, provide a richer massage experience, and improve the massage effect. In other embodiments, the limb massager 100 may only have a cylinder 104, without using the main body 102 to connect the cylinder 104. The user only needs to put the cylinder 104 onto the limb to perform the corresponding massage actions.

[0022] In this embodiment, the limb massager 100 has two cylinders 104, each disposed at the lower end of the main body 102, respectively for the user's two legs to insert into. Each cylinder 104 contains multiple airbags 106 arranged sequentially along its length for massaging different areas of the user's legs. The cylinders 104 are made of an elastic material, such as a resilient fabric. The airbags 106 are embedded within the cylinders 104, and the expanding airbags 106 can deform the elastic material cylinders 104. In some embodiments, the airbags 106 may also be embedded in grooves within the cylinders 104, thereby utilizing the elastic surface of the airbags 106 themselves to compress the user's legs. In other embodiments, the two cylinders 104 may be symmetrically connected at both ends of the main body 102, worn as clothing on the user's body and arms.

[0023] Multiple sensors 110 are also provided inside or on the surface of the cylinder 104 for detecting the user's leg shape. Specifically, in this embodiment, a pressure sensor 110 can be provided for each airbag 106. This pressure sensor 110 can be a Hall sensor 110 or a capacitance sensor 110. As the airbag 106 expands, when the airbag 106 contacts and compresses the user's leg, there is a certain interaction force between the two. In some embodiments, the cross-sectional size of the user's leg at the location of the sensor 110 can be calculated by the force change curve during this inflation process. Furthermore, the user's leg shape and the current wearing position can be inferred by combining the measurement results of multiple sensors 110. In other embodiments, the cross-sectional area of ​​the user's leg can also be calculated based on the air pressure value of the airbag 106 and the pressure of the sensor 110 after the airbag 106 has compacted the leg. The relevant algorithms and the placement of the sensors 110 are well known to those skilled in the art, and will not be described in detail here.

[0024] Through the above methods, multiple sensors 110 can be used quickly and effectively to infer the user's leg shape and the current wearing position of the limb massager 100 relative to the user's leg. Furthermore, in the limb massager 100 provided in this embodiment, the airbag 106 is movably installed inside the cylinder 104, specifically, it can move along the length of the cylinder 104. The movement of the airbag 106 is driven by the drive unit 112. The drive unit 112 and the sensors 110 are all communicatively connected to the control unit. Based on the detection results of the sensors 110, the control unit can calculate the leg shape and wearing position, and then use the drive unit 112 to control the airbag 106 to move to the target massage position to massage the target massage position on the leg. The drive unit 112, composed of the flexible track 114 and the walking motor 116, can accurately deliver the airbag 106 to the target massage position without affecting or minimally affecting the wearing comfort of the limb massager 100.

[0025] In this embodiment, the drive unit 112 includes a flexible track 114 and a walking motor 116. The flexible track 114 is disposed inside the cylinder 104 and extends along the length direction of the cylinder 104. One side of the walking motor 116 is fixedly connected to the airbag 106, and the other side is assembled to the flexible track 114, so as to be movably connected in a way that it can move along the length direction of the flexible track 114.

[0026] The electronic control unit of the limb massager 100 specifically includes a power supply module (not shown) and a control unit. The power supply module is electrically connected to the control unit, the drive unit 112, and the pump 108, providing power to these components. The power supply module can be an external power source or a battery built into the limb sensor 110.

[0027] The control unit includes a control circuit board and a control panel 118. The control panel 118 is equipped with controls for user operation, allowing the user to control the operation of the pump 108 and the drive unit 112. For example, in some embodiments, the control panel 118 may provide the user with controls to adjust the massage position, allowing the user to actively adjust the target massage position.

[0028] <Work Process>

[0029] The following is a brief introduction to the use of the limb massager 100.

[0030] When a new user uses the device, the limb massager 100 is worn in a suitable position. Specifically, in this embodiment, after wearing the limb massager 100, the cylinder 104 wraps around the user's legs, and the main body 102 is worn around the user's lower abdomen and buttocks.

[0031] After the user is comfortable wearing the device, turn on the limb massager 100. Once the limb massager 100 has initialized, it recognizes the user as a new user and activates the various sensors 110 to execute a leg shape detection program. After each sensor 110 detects dimensional data at various locations, such as the cross-sectional dimensions of the legs, it combines this data to obtain the user's leg shape data and the current wearing position data.

[0032] Next, based on the detection results including leg shape data and wearing position, the zero point of the airbag 106 and / or the zero point of the massage mechanism are calibrated and saved as a personalized archive for the new user. In subsequent processing, various massage programs are executed based on this zero point. For example, in a calf massage program, the calibrated zero point can be used to accurately identify the precise position of the new user's calf in the current wearing state based on leg shape data and wearing position. Finally, the drive unit 112 accurately moves the airbag 106 to the target massage position to perform a massage action on the calf.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
