Description

Technical Field

[0001] This application relates to the field of massage technology, specifically to a massage product with different massage methods. Background Technology

[0002] As people's demands for quality of life and health care continue to rise, massage products are being used more and more widely. To cater to the massage needs of different parts of the body, the market has developed a variety of massage products with different structures and working methods to meet users' needs for soothing, relaxation, and different massage sensations.

[0003] Currently, massage products on the market typically employ a single massage method to stimulate the body. This can be achieved through mechanical movements such as the reciprocating movement, oscillation, or vibration of massage components, or by altering the air pressure between the massage area and the body to create suction or release effects. Different massage methods provide different sensations, and users have varying preferences when choosing a massage method.

[0004] However, existing massage products are typically designed for specific massage methods, with different methods often incorporated into separate products. For example, products using mechanical reciprocating motion primarily offer a moving or oscillating massage experience, while products using air pressure variations mainly provide a suction or pressure-changing massage experience. Consequently, when users wish to experience different massage methods, they usually need to use products with different massage functions, making the process rather inconvenient.

[0005] Therefore, how to provide a richer massage experience in massage products, enabling users to obtain different forms of massage effects while using the same massage product, and at the same time taking into account the rationality of the product structure and ease of use, is a problem that needs further research and solutions in this field. This application content

[0006] The purpose of this application is to overcome the shortcomings and deficiencies of the prior art and provide a massage product with different massage methods.

[0007] This application is achieved through the following technical solution: A massager includes a body, a drive source, a first flexible sleeve, two clamping arms, and a second flexible sleeve. The drive source is fixed to the body. The first flexible sleeve is fixed to the body and defines a first cavity and a first opening communicating with the first cavity. The two clamping arms are rotatably connected to the body, and are at least partially built into opposite sides of the first flexible sleeve. Driven by the drive source, the two clamping arms reciprocate by moving closer and further apart at a first frequency, thereby causing the first flexible sleeve to massage a first human body part covered by the first opening. The second flexible sleeve is fixed to the body and defines a second cavity at least partially located within the first cavity and a second opening communicating with the second cavity. Driven by the drive source, the second flexible sleeve causes the air pressure in the second cavity to alternate between the first and second air pressures at a second frequency, thereby massaging a second human body part covered by the second opening. The second human body part is covered by the first human body part. The second frequency is 9 to 50 times the first frequency.

[0008] The technical solution of this application enables different forms of massage to be achieved on the same product. By setting a first flexible sleeve and a second flexible sleeve on the main body, and employing reciprocating motion massage and air pressure variation massage respectively, this application allows users to obtain different forms of massage experience while using the same massage device. This eliminates the need to purchase and use different massage products for different massage methods, thereby improving the product's ease of use and functional versatility. Simultaneously, it can also create a composite massage effect. The drive source can drive the two clamping arms to reciprocate at a first frequency, causing the first flexible sleeve to reciprocate and deform accordingly, thus creating a reciprocating motion massage on the first body part. At the same time, the drive source can also cause the air pressure in the second cavity of the second flexible sleeve to alternate between the first and second air pressures at a second frequency, thereby creating an air pressure massage on the second body part covered by the second opening. Therefore, mechanical reciprocating massage and air pressure variation massage can be combined during the same use, providing users with a richer massage experience. Furthermore, different massage rhythms can be created through different frequencies. The reciprocating motion of the first flexible sleeve has a first frequency, and the air pressure change in the second flexible sleeve has a second frequency. By setting the first frequency and the second frequency, the mechanical reciprocating massage and the air pressure change massage can have different rhythms, thereby forming a richer composite massage effect.

[0009] In some embodiments, the second flexible sleeve includes an upper portion defining the second opening and a lower portion connected to the drive source. The lower portion deforms under the drive source, causing a change in the volume of the second cavity, thereby generating alternating changes in the first and second air pressures.

[0010] Therefore, by using the method of connecting the upper and lower parts, the manufacturing cost of the second flexible sleeve can be reduced.

[0011] In some embodiments, the lower portion includes a deformable portion that is made of silicone and has a thickness between 0.5 and 1 mm.

[0012] This facilitates deformation of the deformable part, thereby causing pressure changes within the second cavity.

[0013] In some embodiments, the upper part defines an upper cavity, the lower part defines a lower cavity, and the second cavity includes the upper cavity, the lower cavity, and a connecting cavity that connects the upper cavity and the lower cavity, wherein the cross-sectional area of ​​the connecting cavity is smaller than the cross-sectional area of ​​the upper cavity and the lower cavity.

[0014] In this way, the airflow exchange between the upper and lower cavities can be restricted, allowing the periodic deformation of the lower part to create corresponding pressure fluctuations within the upper cavity. This facilitates the alternating changes in the first and second air pressures at the second opening. Simultaneously, the upper and lower parts form relatively independent cavity regions through the connecting cavity, allowing the lower part to act as the primary deformation-driving area, while the upper part maintains a relatively stable shape. This reduces direct mechanical disturbance from the driving source to the second opening, enabling the second opening to primarily exert a massaging effect on the second body part through air pressure changes.

[0015] In some embodiments, the upper portion retracts inward on the side away from the second opening to form at least part of the communicating cavity.

[0016] In this way, the upper mechanical structure is more stable, which further helps to maintain a close fit between the second opening and the local area of ​​the human body.

[0017] In some embodiments, the second flexible sleeve further includes a portion fixed to the middle of the body, the middle portion defining at least a portion of the communicating cavity; the opposite sides of the middle portion are respectively connected to the upper and lower portions.

[0018] In some embodiments, the first flexible sleeve includes an outer sleeve connected to the body and a connecting sleeve extending from the side of the outer sleeve away from the body toward the side of the body; the outer sleeve forms the first opening on the side away from the body, and at least the side of the first cavity is surrounded by the connecting sleeve; the outer sleeve and the connecting sleeve are spaced apart and clamp at least a portion of the two clamping arms in the middle, so that the two clamping arms can cause the first flexible sleeve to deform.

[0019] This allows the first flexible sleeve to undergo a certain elastic deformation at the first opening, which in turn facilitates the fit between the first opening and the human body.

[0020] In some embodiments, the first flexible sleeve further includes an inner sleeve extending from the side of the connecting sleeve near the body in a direction away from the body, and the second flexible sleeve is connected to the side of the inner sleeve away from the body.

[0021] This facilitates the installation and fixation of the second flexible sleeve, and also makes it easier to check the connection and sealing effect after installation.

[0022] In some embodiments, the first flexible sleeve includes a first contact end that is away from the body and defines the first opening; the first contact end includes opposing first and second sides, and opposing third and fourth sides, the first and second sides being further away from the body relative to the third and fourth sides; the second flexible sleeve includes a second contact end that is away from the body and defines the second opening, the second contact end being closer to the body relative to the third and fourth sides.

[0023] Thus, viewed from a specific side, the first contact end of the first flexible sleeve is arc-shaped, and the second contact end of the second flexible sleeve is located below this arc. With this configuration, the arc shape can better conform to certain arc-shaped parts of the human body, resulting in a better massage effect; simultaneously, the second contact end being located below this arc ensures that the height of the second opening better matches certain parts of the human body, and when used as a full-body massage tool, slightly more pressure is required for the second opening to contact the body, thus guaranteeing the massage intensity of the first flexible sleeve on the covered areas.

[0024] In some embodiments, the two clamping arms are respectively disposed on the first side and the second side of the first contact end.

[0025] This allows the clamping arm to be set as long as possible, resulting in a better driving effect.

[0026] In some embodiments, the drive source includes a drive motor and a reversing assembly with a reversing wheel; the drive motor includes a motor shaft that outputs power and rotates about a first direction; the reversing assembly is connected to the motor shaft and causes the reversing wheel to rotate about a second direction, the first and second directions intersecting; of the two clamping arms and the second flexible sleeve, one is connected to the motor shaft and the other is connected to the reversing wheel.

[0027] In this way, the commutation component enables one power output from the drive motor to provide power in different directions to two massage mechanisms simultaneously, which helps to reduce the number of drive motors.

[0028] In some embodiments, the reversing assembly further includes a worm gear connected to the motor shaft, and the reversing wheel is a worm wheel that meshes with the worm gear.

[0029] In this way, the commutator and worm can maintain a stable meshing state after the motor stops.

[0030] In some embodiments, the drive source further includes a first drive assembly and a second drive assembly; the two clamping arms are connected to one of the motor shaft or the commutator wheel via the first drive assembly, and the second flexible sleeve is connected to the other of the motor shaft or the commutator wheel via the second drive assembly.

[0031] Thus, since the power for both clamping arms and the second flexible sleeve comes from the same drive motor, the reciprocating motion of the two clamping arms and the deformation motion of the second flexible sleeve can form a definite motion relationship. Through the transmission relationship of the first drive component, the second drive component and the reversing component, the motion frequency of the two can be configured, thereby creating a composite massage effect of different frequencies between mechanical reciprocating massage and air pressure change massage.

[0032] In some implementations, the first frequency is 100-160 times / minute, and the second frequency is 1500-5000 times / minute.

[0033] In some embodiments, the second flexible sleeve is connected to the reversing wheel via the second drive assembly; the second drive assembly includes a U-shaped tie rod and two eccentric wheels respectively disposed on both axial sides of the reversing wheel; the U-shaped tie rod includes a top end connected to the second flexible sleeve and a connecting end located on both sides of the U-shaped opening; each eccentric wheel includes a rotating part and an eccentric part, the rotating part is fixedly connected to the reversing wheel, and the eccentric part is rotatably connected to a corresponding connecting end of the U-shaped tie rod, the rotating part and the eccentric part are not coaxial, thereby causing the connecting end to rotate around the rotating part.

[0034] In some embodiments, the two clamping arms are connected to the motor shaft via the first drive assembly; the first drive assembly includes a reduction assembly connected to the motor shaft to increase torque and an actuation assembly connected to the reduction assembly to drive the two clamping arms to perform the reciprocating motion; the actuation assembly includes two actuation connection portions driven by the drive motor and performing periodic movements of moving closer to each other and moving further away from each other while rotating simultaneously; each clamping arm includes a first clamping arm end built into the first flexible sleeve, a second clamping arm end opposite to the first clamping arm end, and a clamping arm connection portion located between the first and second clamping arm ends; each clamping arm connection portion is rotatably connected to the body, and each second clamping arm end is rotatably connected to the corresponding actuation connection portion.

[0035] In some embodiments, the actuation assembly includes an intermediate gear connected to the reduction assembly and two connecting gears respectively meshing with opposite sides of the intermediate gear, the two actuation connecting parts being eccentrically disposed on the two connecting gears.

[0036] In some embodiments, the actuation assembly includes an eccentric wheel member connected to the reduction assembly and two rotating push rods; the eccentric wheel member includes two circular sub-eccentric wheels that are eccentrically mounted and stacked on top of each other in opposite radial directions, and each rotating push rod includes a ring rotatably fitted onto the corresponding sub-eccentric wheel and a push rod extending outward from the ring; the two actuation connection portions are respectively located on the side of the two push rods away from the rings they are connected to.

[0037] In some embodiments, the actuation assembly further includes a pressure cap fixed to the eccentric wheel member, the pressure cap being located above the two rings to prevent the two rings from disengaging from their respective eccentric wheels.

[0038] In some embodiments, the drive source includes a first drive source and a second drive source; the first drive source includes a first power source and an actuation component connected between the first power source and the two clamping arms, thereby driving the two clamping arms to perform the reciprocating motion; the second drive source includes a second power source and a drive component connected between the second power source and the second flexible sleeve, thereby driving the second flexible sleeve to generate the alternating changes of the first air pressure and the second air pressure.

[0039] In some embodiments, the first power source includes a first motor; the actuation assembly includes two actuation connection portions driven by the first motor and performing periodic movements of approaching and moving away from each other while rotating simultaneously; each clamping arm includes a first clamping arm end built into the first flexible sleeve, a second clamping arm end opposite to the first clamping arm end, and a clamping arm connection portion located between the first and second clamping arm ends, each clamping arm connection portion being rotatably connected to the body, and each second clamping arm end being rotatably connected to the corresponding actuation connection portion.

[0040] In some embodiments, the actuation assembly includes an intermediate gear connected to the first motor and two connecting gears respectively meshing with opposite sides of the intermediate gear, the two actuation connecting parts being eccentrically disposed on the two connecting gears.

[0041] In some embodiments, the actuation assembly includes an eccentric wheel member connected to the first motor and two rotating push rods; the eccentric wheel member includes two circular sub-eccentric wheels that are eccentrically mounted and stacked on top of each other in opposite radial directions, and each rotating push rod includes a ring rotatably fitted onto the corresponding sub-eccentric wheel and a push rod extending outward from the ring; the two actuation connection portions are respectively located on the side of the two push rods away from the rings they are connected to.

[0042] In some embodiments, the actuation assembly further includes a pressure cap fixed to the eccentric wheel member, the pressure cap being located above the two rings to prevent the two rings from disengaging from their respective eccentric wheels.

[0043] In some embodiments, the second power source includes a second motor, which includes a stator and output shafts extending to opposite sides of the stator; the drive assembly includes a U-shaped tie rod and two eccentric wheels respectively disposed on opposite axial sides of the output shaft; the U-shaped tie rod includes a top end connected to the second flexible sleeve and connecting ends located on both sides of the U-shaped opening; each eccentric wheel includes a rotating part and an eccentric part, the rotating part being fixedly connected to the output shaft, and the eccentric part being rotatably connected to a corresponding connecting end of the U-shaped tie rod, the rotating part and the eccentric part being non-axial, thereby causing the connecting end to rotate around the rotating part.

[0044] In some implementations, the second frequency is 15.6 to 50 times the first frequency.

[0045] In some implementations, the first frequency is 100-160 times / minute, and the second frequency is 2500-5000 times / minute.

[0046] In some embodiments, the second power source includes a housing, a sliding magnet, and a coil. The housing defines a cylindrical sliding cavity and a first air port and a second air port that are respectively connected to opposite axial sides of the sliding cavity. The sliding magnet is tightly housed in the sliding cavity and can slide along the axial direction of the sliding cavity. The coil is wound on the surface of the housing at a position corresponding to the sliding cavity to generate an electromagnetic field with alternating directions. The sliding magnet reciprocates within the sliding cavity under the action of the electromagnetic field. The drive assembly includes a vent pipe connecting the first air port and the second cavity. The second air port is connected to the outside of the sliding cavity.

[0047] In some embodiments, the second frequency is 9.4 to 30 times the first frequency. In some embodiments, the first frequency is 100-160 times / minute, and the second frequency is 1500-3000 times / minute.

[0048] In some embodiments, the second power source further includes a first magnet and a second magnet disposed on opposite sides of the sliding cavity in the axial direction, wherein the first magnet and the sliding magnet have the same polarity on the side facing each other, and the second magnet and the sliding magnet have the same polarity on the side facing each other.

[0049] In some embodiments, the pressure difference between the first and second air pressures within the second cavity of the second flexible sleeve is greater than or equal to 20 kPa.

[0050] Thus, through the above-mentioned arrangement, alternating pressure changes with a large pressure variation range can be formed in the second cavity, which helps to increase the degree of significance of pressure changes at the second opening.

[0051] In some embodiments, the first pressure is a positive pressure greater than the ambient pressure, the second pressure is a negative pressure less than the ambient pressure, and the absolute value of the negative pressure is four times or more the positive pressure.

[0052] By making the absolute value of the negative pressure significantly greater than the positive pressure, the pressure changes within the second cavity are primarily driven by negative pressure stimulation, with positive pressure changes playing a secondary role. This helps to highlight the suction-massage effect at the second opening and create a massage effect with a more pronounced alternating sensation of suction and release.

[0053] In some implementations, the second frequency is 20 to 30 times the first frequency. Attached Figure Description

Detailed Implementation

[0056] In this application, the terms "set up," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a direct connection, an indirect connection via an intermediate medium, or an internal connection between two devices, elements, or components. Furthermore, "fixed connection" can also mean a connection that is normally in a connected state, but does not exclude the possibility of detachment. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0057] The terms “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “radial,” and “circumferential” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0058] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0059] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0060] Please combine Figure 1-12This application discloses a massager, including a body 100, a drive source 200, clamping arms 300, a first flexible sleeve 400, and a second flexible sleeve 500. The drive source 200 is fixed to the body 100. The first flexible sleeve 400 is also fixed to the body 100 and defines a first cavity 41 and a first opening 43 communicating with the first cavity 41. Two clamping arms 300 are rotatably connected to the body 100. The two clamping arms 300 are at least partially built into opposite sides of the first flexible sleeve 400 and can reciprocate by moving closer and further away from each other at a first frequency under the drive of the drive source 200, thereby causing the first flexible sleeve 400 to massage a first human body part covered by the first opening 43. The second flexible sleeve 500 is fixed to the body 100 and defines a second cavity 51 and a second opening 53. The second cavity 51 is at least partially located within the first cavity 41, and the second opening 53 communicates with the second cavity 51. The second flexible sleeve 500, driven by the driving source 200, causes the air pressure inside the second cavity 51 to alternate between the first and second air pressures at a second frequency, thereby massaging the second human body part covered by the second opening 53. The second human body part is covered by the first human body part. The second frequency is 9 to 50 times the first frequency.

[0061] Under this technical solution, the user can hold the main body 100 and align the first opening 43 of the first flexible sleeve 400 with the first human body part to be massaged. At this time, the second opening 53 of the second flexible sleeve 500 is aligned with the second human body part within the first human body part. Alternatively, the user can first align the second opening 53 of the second flexible sleeve 500 with the second human body part to be massaged, and the first opening 43 of the first flexible sleeve 400 will cover a larger area of ​​the first human body part. At this time, the first opening 43 and the second opening 53 are completely covered by the human body part, and the first cavity 41 and the second cavity 51 are in a sealed state. Simultaneously, the drive source 200 drives the two clamping arms 300 to reciprocate at a first frequency, and the first flexible sleeve massages the first human body part under the action of the two clamping arms 300. At the same time, the drive source 200 also drives the air pressure in the second cavity 51 of the second flexible sleeve 500 to alternate between the first air pressure and the second air pressure at a second frequency, thereby achieving massage of the second human body part covered by the second opening.

[0062] Through the applicant's experimentation-feedback-modification process, and after extensive research, it was found that when the frequency of alternating first and second air pressures within the second cavity 51 (i.e., the second frequency) is set to 9 to 50 times (greater than or equal to 9 and less than or equal to 50) the frequency of the reciprocating motion of the two clamping arms 300 (i.e., the first frequency), the second cavity 51 can undergo multiple cycles of alternating first and second air pressures during one reciprocating motion of the two clamping arms 300. This allows the low-frequency reciprocating motion massage generated by the first flexible sleeve 400 and the high-frequency air pressure change massage generated by the second flexible sleeve 500 to form a composite massage effect with different frequency levels. Therefore, limiting the ratio of the second frequency to the first frequency to the range of 9 to 50 allows for a more obvious rhythmic difference between the two massage methods, enhancing the richness of the massage experience. Furthermore, it reduces the rhythmic overlap and mutual interference caused by the close frequency of the two massage methods, enabling the first and second body parts to receive massage stimulation with different time scales.

[0063] For example, the first frequency can be set to 100-160 times / minute, and the second frequency to 2500-5000 times / minute, in which case the second frequency is 15.6 to 50 times the first frequency; the first frequency can be set to 100-160 times / minute, and the second frequency to 1500-3000 times / minute, in which case the second frequency is 9.4 to 30 times the first frequency; the first frequency can be set to 120 times / minute, and the second frequency to 1080 times / minute, in which case the second frequency is 9 times the first frequency; the first frequency can be set to 120 times / minute, and the second frequency to 2400 times / minute, in which case the second frequency is 20 times the first frequency; the first frequency can be set to 140 times / minute, and the second frequency to 4200 times / minute, in which case the second frequency is 30 times the first frequency; the first frequency can be set to 120 times / minute, and the second frequency to 4800 times / minute, in which case the second frequency is 40 times the first frequency. The combinations of the above discrete points or ranges are also within the scope of protection of this application.

[0064] It should be noted that the aforementioned first frequency refers to the number of times the two clamping arms 300 complete a full reciprocating motion per unit time when the system is unloaded (i.e., the first flexible sleeve 400 is not acting on the human body or any external object). When the system is not unloaded (e.g., the first opening 43 is acting on the human body), the frequency will vary depending on the amount of force applied by the user. The second frequency refers to the number of times the air pressure within the second cavity 51 alternates between the first and second air pressures per unit time when the second opening 53 is completely covered (e.g., the second opening 53 is in complete contact with the user's skin).

[0065] Furthermore, the reciprocating motion described in this application does not necessarily mean that the travel distance in each reciprocation must be equal. For example, the travel distance to the left in the later reciprocation may be greater than that in the previous reciprocation. Similarly, it does not necessarily mean that the pressure values ​​in the first and second air pressures are the same each time. For example, the absolute value of the negative pressure in the later reciprocation may be smaller than that in the previous reciprocation.

[0066] It should also be noted that the massager of this application does not limit the working sequence of the first drive source 22 and the second drive source 24. During operation, while the first drive source 22 drives the two clamping arms 300 to massage the first human body part through the first flexible sleeve 400, the second drive source 24 can simultaneously drive the second flexible sleeve 500 to massage the second human body part; or, during the massage of the first flexible sleeve 400, the second flexible sleeve 500 pauses its massage, and vice versa, alternating in this manner; or, the massage periods of the first flexible sleeve 400 and the second flexible sleeve 500 partially overlap, for example, the first flexible sleeve 400 massages for 10 seconds and then pauses, while the second flexible sleeve 500 resumes its massage at the 5th second. Furthermore, the user can be configured to choose to use only the first flexible sleeve 400 or only the second flexible sleeve 500 for massage.

[0067] Compared with the prior art, the massage device provided in this application has the following beneficial effects: 1. The product can provide different forms of massage on the same product. This application provides a first flexible sleeve 400 and a second flexible sleeve 500 on the main body 100, and uses reciprocating motion massage and air pressure change massage respectively, so that users can get different forms of massage experience when using the same massage device. This eliminates the need to purchase and use different massage products for different massage methods, thereby improving the convenience and functional diversity of the product.

[0068] 2. Capable of creating a composite massage effect. The drive source 200 can drive the two clamping arms 300 to reciprocate at a first frequency, causing the first flexible sleeve 400 to reciprocate and deform accordingly with the two clamping arms 300, thereby creating a reciprocating massage on the first human body part; simultaneously, the drive source 200 can also cause the air pressure in the second cavity 51 of the second flexible sleeve 500 to alternate between the first and second air pressures at a second frequency, thereby creating an air pressure massage on the second human body part covered by the second opening 53. Thus, mechanical reciprocating massage and air pressure variation massage can be combined in the same use, providing users with a richer massage experience.

[0069] 3. Different massage rhythms can be formed by different frequencies. The reciprocating motion of the first flexible sleeve 400 has a first frequency, and the air pressure change in the second flexible sleeve 500 has a second frequency. By setting the first frequency and the second frequency, the mechanical reciprocating massage and the air pressure change massage can have different rhythms, thereby forming a richer composite massage effect.

[0070] The aforementioned massager has multiple implementation methods. To make the technical solution of this application clearer, the following describes this application in further detail with reference to the accompanying drawings and multiple embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0071] It should be noted that the aforementioned alternating change of the first and second air pressures refers to the change within the second cavity 51 from the first air pressure to the second air pressure and then back to the first air pressure; it can be an alternating change between ambient air pressure and negative pressure lower than ambient air pressure, or an alternating change between positive pressure higher than ambient air pressure and negative pressure lower than ambient air pressure, etc. In the following embodiments, the alternating change between positive and negative pressure will be used as an example for explanation.

[0072] Implementation Method 1 like Figures 1 to 5 As shown, the massager of this embodiment includes a main body 100, a drive source 200, a clamping arm 300, a first flexible sleeve 400, and a second flexible sleeve 500. The main body includes a conical housing 12 and a support 14 located approximately inside the housing. An accommodating space is formed inside the housing for accommodating a PCB circuit board 11a, buttons 11b, a battery 11c, etc., used to control the drive source. A battery charging port 11d may also be provided on the housing. Although the housing is conical in this embodiment and the following embodiments, it should be understood that the shape of the housing is not limited to a conical shape; any shape that allows the user to hold and accommodate the aforementioned components is acceptable. Further details will not be provided in subsequent embodiments. The drive source 200, clamping arm 300, first flexible sleeve 400, and second flexible sleeve 500 are connected to the support 14.

[0073] A first flexible sleeve 400 defines a first cavity 41 and a first opening 43 communicating with the first cavity 41. Specifically, the first flexible sleeve 400 includes an outer sleeve 42 connected to the body 100 and a connecting sleeve 44 extending from the side of the outer sleeve away from the body 100 toward the side closer to the body 100. The outer sleeve 42 forms the first opening 43 on the side away from the body 100, and at least the side of the first cavity 41 is surrounded by the connecting sleeve 44. The outer sleeve 42 and the connecting sleeve 44 are spaced apart and clamp at least a portion of the two clamping arms 300 in the middle (e.g., Figure 5As shown), this allows the two clamping arms 300 to deform the first flexible sleeve 400. This folding arrangement facilitates elastic deformation of the first flexible sleeve 400 at the first opening 43, thus improving the fit between the first opening 43 and the human body. Of course, in other embodiments, where strong adaptability is not required, no gap may be provided between the outer sleeve 42 and the connecting sleeve 44 (e.g., Figure 4 As shown), only holes are left for the two clamping arms 300 to be inserted. In this way, the first flexible sleeve 400 will deform better with the clamping arms 300.

[0074] In some embodiments, the first flexible sleeve 400 further includes an inner sleeve 46 extending from the side of the connecting sleeve 44 near the body 100 in a direction away from the body 100. The second flexible sleeve 500 is connected to the side of the inner sleeve 46 away from the body 100. The inner sleeve 46 extends upward a certain distance, which facilitates the installation and fixation of the second flexible sleeve 500, and also makes it easier to check the connection and sealing effect after installation.

[0075] The first flexible sleeve 400, on the side away from the body 100, i.e., the side where the outer sleeve 42 bends to connect with the connecting sleeve 44, forms a first contact end 410 for contact with the human body. The first contact end 410 defines a first opening 43. The first contact end 410 includes opposing first sides 411 and second sides 412, and opposing third sides 413 and fourth sides 414. The first sides 411 and second sides 412 are further away from the body 100 than the third sides 413 and fourth sides 414. The second flexible sleeve 500 includes a second contact end 510 on the side away from the body 100 that defines a second opening 53. The second contact end 510 is closer to the body 100 than the third sides 413 and fourth sides 414 of the first flexible sleeve 400. Thus, viewed from a certain side, the first contact end 410 of the first flexible sleeve 400 is arc-shaped, and the second contact end 510 of the second flexible sleeve 500 is located below this arc. With this setting, the arc shape can better fit certain curved parts of the human body, resulting in a better massage effect; at the same time, the second contact end 510 is located below the arc, which firstly allows the height of the second opening 53 to better match certain parts of the human body, and secondly, when used as a full-body massage tool, it requires a little pressure to make the second opening 53 contact the human body, which can ensure the massage intensity of the first flexible sleeve 400 on the covered parts.

[0076] In some embodiments, the two clamping arms 300 are respectively disposed in the directions of the first side 411 and the second side 412 of the first contact end 410, such as... Figure 1 As shown. Since the first side 411 and the second side 412 are relatively far away from the main body 100, that is, they are relatively long, the two clamping arms 300 are set in this direction, so that the length of the clamping arms 300 can be set as long as possible to achieve a better driving effect.

[0077] The second flexible sleeve 500 defines a second cavity 51 at least partially located within the first cavity 41 and a second opening 53 communicating with the second cavity 51. Specifically, the second flexible sleeve 500 includes an upper portion 52 defining the second opening 53 and a lower portion 54 connected to the driving source 200. The lower portion 54 deforms under the drive of the driving source 200, causing a change in the volume of the second cavity 51, thereby generating the alternating positive and negative pressure. The upper portion 52 and the lower portion 54 are tightly connected to each other by being respectively connected to the bracket 14, defining the second cavity 51. Using a two-part connection reduces the manufacturing cost of the second flexible sleeve 500; however, it should be understood that if the second flexible sleeve 500 is integrally molded, it is also within the scope of the invention of this application.

[0078] In some embodiments, the lower portion 54 includes a deformable portion 542, which is made of silicone and has a thickness between 0.5 and 1 mm (i.e., greater than or equal to 0.5 mm and less than or equal to 1 mm). This facilitates the deformation of the deformable portion 542, thereby creating a pressure change within the second cavity 51. Alternatively, other portions may also be made of silicone and have a relatively thicker thickness for better fixation; similarly, the upper portion 52 may also be made of silicone and have a relatively thicker thickness for better fit upon contact with the human body.

[0079] In some embodiments, the upper part 52 defines an upper cavity 51a, and the lower part 54 defines a lower cavity 51b. The second cavity 51 includes the upper cavity 51a, the lower cavity 51b, and a connecting cavity 51c that connects the upper cavity 51a and the lower cavity 51b. The cross-sectional area of ​​the connecting cavity 51c is smaller than that of the upper cavity 51a and the lower cavity 51b. By providing a connecting cavity 51c with a relatively small cross-sectional area, the airflow exchange between the upper cavity 51a and the lower cavity 51b can be restricted, allowing the periodic deformation of the lower part 54 to form corresponding pressure fluctuations within the upper cavity 51a. This facilitates the formation of alternating positive and negative pressure at the second opening 53. Meanwhile, the upper part 52 and the lower part 54 form a relatively independent cavity area through the connecting cavity 51c, so that the lower part 54 can serve as the main deformation driving area, while the upper part 52 can maintain a relatively stable shape. This helps to reduce the direct mechanical disturbance of the driving source to the second opening 53, so that the second opening 53 mainly produces a massage effect on the second human body part through air pressure changes.

[0080] exist Figure 4 In the illustrated embodiment, the side of the upper portion 52 furthest from the second opening 53 tapers inward to form at least a partially communicating cavity 51c. This feature enhances the mechanical stability of the upper portion 52, further facilitating the maintenance of a close fit between the second opening 53 and the local area of ​​the human body.

[0081] Two clamping arms are arranged opposite to each other. Each clamping arm 300 includes a first clamping arm end 32 built into the first flexible sleeve, a second clamping arm end 34 opposite to the first clamping arm end 32, and a clamping arm connecting portion 36 located between the first clamping arm end 32 and the second clamping arm end 34. Each clamping arm connecting portion 36 is rotatably connected to the bracket 14 of the body 100. The clamping arm connecting portion 36 includes two symmetrically arranged and oppositely extending rotation shafts 362, which are rotatably connected to the bracket 14, so that both the first clamping arm end 32 and the second clamping arm end 34 rotate about the axis defined by the two rotation shafts 362. Thus, when the second clamping arm end 34 is subjected to force and displacement, the first clamping arm end 32 can rotate about the clamping arm connecting portion 36, thereby causing the first flexible sleeve to produce a corresponding deformation. In this embodiment, the clamping arm connecting portion 36 is closer to the second clamping arm end 34 than the first clamping arm end 32, so that a small displacement of the second clamping arm end 34 can produce a large displacement of the first clamping arm end 32.

[0082] The drive source 200 includes a first drive source 22. The first drive source 22 includes a first power source and an actuation assembly 226 connected between the first power source and the two clamping arms 300, thereby driving the two clamping arms to perform the reciprocating motion. In this embodiment, the first power source includes a first motor 222. The first motor 222 is arranged generally along the axial direction of the housing 12 and is used to output power to the actuation assembly 226. The actuation assembly 226 includes an eccentric wheel 226a connected to the first motor 222 and two rotating push rods 226b. The eccentric wheel includes two circular sub-eccentric wheels 226c that are eccentrically positioned in opposite radial directions and stacked vertically. That is, the centers of the two sub-eccentric wheels 226c are located on opposite sides of the position of the eccentric wheel 226a corresponding to the rotation axis of the first motor 222. Each rotating push rod 226b includes a ring 226d rotatably fitted onto the corresponding sub-eccentric wheel 226c and a push rod 226e extending outward from the ring 226d. Each push rod 226e has a connecting portion 226f on the side away from the ring 226d. The connecting portion 226f is rotatably connected to the corresponding second clamping arm end 34. The connecting portion 226f may be spherical, and the second clamping arm end 34 defines a corresponding spherical groove or a partial spherical groove to accommodate the entire or part of the connecting portion 226f, thereby allowing the spherical connecting portion 226f to rotate within the spherical groove or a partial spherical groove of the second clamping arm end 34.

[0083] In other embodiments, the actuation assembly 226 further includes a pressure cap 226g fixed to the eccentric wheel member 226a. The pressure cap 226g is located above the two rings 226d and is used to prevent the two rings 226d from disengaging from their corresponding sub-eccentric wheels 226c. It should be understood that even without the pressure cap 226g, the bracket 14 can provide the same restraining effect on the two rings 226d.

[0084] When the first motor 222 drives the eccentric wheel 226a to rotate, the two sub-eccentric wheels 226c rotate synchronously. During rotation, the centers of the two sub-eccentric wheels 226c periodically approach and move away from each other. The rings 226d fitted on each sub-eccentric wheel 226c move accordingly. However, due to the connection between the rotating shaft 362 and the bracket 14, the clamping arm 300 can only rotate and cannot produce displacement in other dimensions. Therefore, the connecting part 226f is restricted by the second clamping arm end 34. Figure 4 The first flexible sleeve 400 moves back and forth (left and right in the view), thereby causing the first clamping arm end 32 to also move back and forth, and in turn causing the first flexible sleeve 400 to massage the first human body part covered by the first opening 43.

[0085] The drive source 200 also includes a second drive source 24. The second drive source 24 includes a second power source and a drive assembly 244 connected between the second power source and the second flexible sleeve, thereby driving the second flexible sleeve to generate the alternating positive and negative pressure. In this embodiment, the second power source includes a second motor 242, which includes a stator 242a and output shafts 242b extending to opposite sides of the stator 242a. The output shafts 242b are generally perpendicular to the axial direction of the housing 12. The drive assembly 244 includes a U-shaped tie rod 244a and two eccentric wheels 244b respectively disposed on opposite axial sides of the output shaft 242b. The U-shaped tie rod 244a includes a top end 244c connected to the second flexible sleeve 500 and connecting ends 244d located on both sides of the U-shaped opening. Each eccentric wheel 244b includes a rotating part 244e and an eccentric part 244f. The rotating part 244e is fixedly connected to the output shaft 242b, and the eccentric part 244f is rotatably connected to a U-shaped tie rod 244a corresponding to a connecting end 244d. The rotating part 244e and the eccentric part 244f are not on the same axis, so that the connecting end 244d rotates around the rotating part 244e.

[0086] The eccentric wheel 244b may include a cylindrical wheel body and an eccentric shaft. A shaft hole for fixing to the output shaft 242b is provided at the center of the wheel body. The eccentric shaft extends outward from the wheel body along its axial direction and is not coaxial with the shaft hole; for example, it may be located at the edge. In this case, the rotating part 244e may be the shaft hole, and the eccentric part 244f may be the eccentric shaft. Thus, the eccentric shaft rotates around the output shaft 242b. The connecting ends 244d of the U-shaped tie rod 244a located on both sides of the U-shaped opening have connecting holes to accommodate the eccentric shaft of the eccentric wheel 244b. In some embodiments, bearings or bushings may be provided in the connecting holes to reduce friction.

[0087] The second motor 242 rotates, driving the eccentric wheel 244b to rotate. The eccentric shaft then rotates around the axis of the output shaft 242b, meaning the eccentric part 244f rotates around the rotating part 244e. The connecting end 244d of the U-shaped tie rod 244a is driven by the eccentric part 244f in the axial direction of the housing 12 (i.e.,...). Figure 5 The vertical movement of the U-shaped lever 244a causes the second flexible sleeve 500 to deform through its top end 244c, resulting in alternating positive and negative pressure changes in the air pressure inside the second cavity 51, thereby massaging the second human body part covered by the second opening 53.

[0088] In some embodiments, the pressure difference between the positive and negative pressures within the second cavity 51 is greater than or equal to 20 kPa. Preferably, the absolute value of the negative pressure is four times or more than the positive pressure. For example, the positive pressure is 4 kPa higher than the ambient air pressure, while the negative pressure is 16 kPa lower; or the positive pressure is 5 kPa higher than the ambient air pressure, while the negative pressure is 25 kPa lower. In this case, the user can feel a noticeable negative pressure massage, and will not experience discomfort even after prolonged use. Of course, the positive pressure can also be greater, for example, 22 kPa higher than the ambient air pressure, while the negative pressure is 18 kPa lower. In this case, this pressure difference can also provide a noticeable massage sensation.

[0089] Through the above-described configuration, alternating positive and negative pressure changes with a significant range can be formed within the second cavity 51, thereby enhancing the noticeability of air pressure changes at the second opening 53. Simultaneously, by ensuring that the absolute value of the negative pressure is significantly greater than the positive pressure, the pressure changes within the second cavity 51 are primarily driven by negative pressure stimulation, with positive pressure changes playing a secondary role. This enhances the suction-massage effect at the second opening 53, creating a massage effect with a pronounced alternating sensation of suction and release.

[0090] Implementation Method 2 The massager of the second embodiment of this application differs from the first embodiment in that the driving source includes an actuation component of the first driving source and a second driving source.

[0091] Please combine Figures 6 to 8 In this embodiment, the actuation component 224 of the first drive source includes an intermediate gear 224a and two connecting gears 224b located on opposite sides of the intermediate gear 224a. Each connecting gear 224b is eccentrically provided with a connecting shaft 224c, that is, the connecting shaft 224c is located off-axis from the rotation axis of the connecting gear 224b, such as the radial outer edge of the connecting gear 224b. During operation, the first motor drives the intermediate gear 224a to rotate, and the two connecting gears 224b are driven to rotate in opposite directions, causing the two connecting shafts 224c to periodically approach and move away from each other. In this embodiment, each second clamping arm end 34 defines a strip-shaped groove that matches the connecting shaft 224c to accommodate the sliding of the connecting shaft 224c therein. Similarly, the two connecting shafts 224c drive the first clamping arm end 32 to reciprocate, thereby causing the first flexible sleeve 400 to massage the first human body part covered by the first opening 43.

[0092] As can be seen from the actuation component 224 of this embodiment and the actuation component 226 of the first embodiment, both the connecting shaft 224c and the connecting part 226f serve as actuating connecting parts, driving the corresponding clamping arms 300. Their driving process involves periodic movements of approaching and moving away from each other while rotating simultaneously; only the specific structures differ. Therefore, those skilled in the art should understand that as long as the actuation component includes two actuating connecting parts driven by the first motor and performing periodic movements of approaching and moving away from each other while rotating simultaneously, it can drive the clamping arms 300 to reciprocate.

[0093] The second driving source 26 also includes a second power source and a driving assembly connected between the second power source and the second flexible sleeve, but the second power source and driving assembly differ from those in the first embodiment. In this embodiment, the second power source includes a housing 261, a sliding magnet 263, and a coil 265. The housing 261 defines a cylindrical sliding cavity 261a and a first air port 261b and a second air port 261c, respectively connected to opposite sides of the sliding cavity 261a in the axial direction. The sliding magnet 263 is tightly housed within the sliding cavity 261a and can slide along the axial direction of the sliding cavity 261a. The coil 265 is wound around the surface of the housing 261 at a position corresponding to the sliding cavity 261a, for generating an electromagnetic field with alternating directions. Under the action of this electromagnetic field, the sliding magnet 263 reciprocates within the sliding cavity 261a. The driving assembly includes a vent pipe 262 connecting the first air port 261b and the second cavity 51, while the second air port 261c connects to the outside of the sliding cavity 261a.

[0094] During operation, the control coil 265 generates an electromagnetic field with alternating directions, and the sliding magnet 263 is periodically driven to slide in opposite directions within this changing electromagnetic field. Since the sliding magnet 263 is tightly housed within the sliding cavity 261a, it can slide along the axial direction of the sliding cavity 261a while simultaneously driving most of the gas within the sliding cavity 261a to enter or exit through the first air port 261b or the second air port 261c. Therefore, when the sliding magnet 263 slides away from the first air port 261b, the gas within the second cavity 51 of the second flexible sleeve 500 is drawn into the sliding cavity 261a through the vent pipe 262, thereby generating a negative pressure within the second cavity 51; simultaneously, some of the gas within the sliding cavity 261a is discharged through the second air port 261c. When the sliding magnet 263 slides towards the first air inlet 261b, the airflow direction within the first air inlet 261b and the second air inlet 261c is opposite to that described above, generating positive pressure within the second cavity 51. This creates an alternating positive and negative pressure massage effect.

[0095] In some embodiments, the second power source further includes a first magnet 267 and a second magnet 269 disposed on opposite sides of the sliding cavity 261a in an axial direction. The first magnet 267 and the sliding magnet 263 each have the same polarity on their respective sides facing each other, and the second magnet 269 and the sliding magnet 263 each have the same polarity on their respective sides facing each other. For example, the polarity can be as follows: Figure 8 As shown. Thus, when the sliding magnet 263 slides to near the end of the sliding cavity 261a, it will be subjected to the repulsive force of the corresponding first magnet 267 or second magnet 269, which helps the sliding magnet 263 to change its sliding direction.

[0096] Implementation Method 3 The massager in the third embodiment of this application differs from the first embodiment in its driving source. Please refer to... Figure 9-11 In this embodiment, the drive source 200 includes a drive motor 21, a commutation component 23, a first drive component 25, and a second drive component 27.

[0097] Specifically, the drive motor 21 includes a motor shaft 211 that outputs power and rotates about a first direction. A commutation assembly 23 is connected to the motor shaft 211 and has a commutation wheel 233 that rotates about a second direction, which intersects the first and second directions. One of the two clamping arms 300 and the second flexible sleeve 500 is connected to the motor shaft 211, and the other of the two clamping arms 300 and the second flexible sleeve 500 is connected to the commutation wheel 233. The commutation assembly 23 enables one power output from the drive motor 21 to simultaneously provide power in different directions to two massage mechanisms, which helps to reduce the number of drive motors.

[0098] Correspondingly, the two clamping arms 300 are connected to one of the motor shaft 211 or the reversing wheel 233 via the first drive assembly 25, and the second flexible sleeve 500 is connected to the other of the motor shaft 211 or the reversing wheel 233 via the second drive assembly 27. In this embodiment, the first direction is the axial direction of the housing 12 (i.e., Figure 10 The first direction is perpendicular to the second direction (vertical direction); the two clamping arms 300 are (indirectly) connected to the motor shaft 211, and the second flexible sleeve 500 is (indirectly) connected to the reversing wheel 233; the second flexible sleeve 500 is connected to the reversing wheel 233 through the second drive assembly 27, and the two clamping arms 300 are connected to the motor shaft 211 through the first drive assembly 25. However, it should be understood that in other embodiments, the reverse can also be true, for example, when the drive motor 21 is opposite to the first direction. Figure 10 When the position is rotated 90 degrees, the two clamping arms 300 can be (indirectly) connected to the reversing wheel 233, and the second flexible sleeve 500 can be (indirectly) connected to the motor shaft 211.

[0099] Since the power for both clamping arms 300 and the second flexible sleeve 500 comes from the same drive motor 211, the reciprocating motion of the two clamping arms 300 and the deformation motion of the second flexible sleeve 500 can form a definite motion relationship. Through the transmission relationship of the first drive component 25, the second drive component 27 and the reversing component 23, the motion frequency of the two can be configured, so that mechanical reciprocating massage and air pressure change massage can form a composite massage effect with different frequencies.

[0100] In some embodiments, the commutation assembly 23 further includes a worm 231 connected to the motor shaft 211, and a commutation wheel 233 is a worm gear meshing with the worm 231. Through the combination of the worm gear and worm wheel, a stable meshing state can be maintained between the commutation wheel 233 and the worm 231 after the motor stops.

[0101] The first drive assembly 25 includes a reduction assembly 251 connected to the motor shaft 211 to increase torque, and an actuator assembly 253 connected to the reduction assembly 251 and driving the two clamping arms 300 to perform the reciprocating motion. The reduction assembly 251 includes multiple reduction gears 251a, which reduce the rotational speed while increasing torque; this is prior art and will not be described in detail here. The actuator assembly 253 includes an intermediate gear 253a and two connecting gears 253b located on opposite sides of the intermediate gear 253a. The structure and working principle of the actuator assembly 253 are the same as those of the actuator assembly 224 in Embodiment 2, and will not be described in detail here.

[0102] The second drive assembly 27 includes a U-shaped tie rod 271 and two eccentric wheels 273 respectively disposed on both axial sides of the reversing wheel 233. The U-shaped tie rod 271 includes a top end 271a connected to the second flexible sleeve 500 and connecting ends 271b located on both sides of the U-shaped opening. Each eccentric wheel 273 includes a rotating part 273a and an eccentric part 273b. The rotating part 273a is fixedly connected to the reversing wheel 233, and the eccentric part 273b is rotatably connected to a corresponding connecting end 271b of the U-shaped tie rod 271. The rotating part 273a and the eccentric part 273b are not coaxial, so that the connecting end 271b rotates around the rotating part 273a. The structure and working principle of the second drive assembly 27 in this embodiment are the same as those of the drive assembly 244 in Embodiment 1, and will not be described in detail here.

[0103] In this embodiment, only one drive motor 21 is used to drive the two clamping arms 300 to reciprocate and the second cavity of the second flexible sleeve 500 to alternate between positive and negative pressure. Compared with the previous two embodiments, this can save costs and reduce the overall weight.

[0104] In addition, in this embodiment, the second flexible sleeve also includes a central portion 56 fixed to the body 100, the central portion 56 defining at least a portion of the communicating cavity 51c. The central portion 56 is connected to the upper portion 52 and the lower portion 54 on opposite sides, respectively. The provision of the central portion 56 can extend the length of the communicating cavity 51c.

[0105] Implementation Method 4 Please combine Figure 12 The massager of the fourth embodiment of this application differs from that of the third embodiment in the actuation component of the first drive assembly. In this embodiment, the actuation component 255 includes an eccentric wheel 255a connected to the reduction assembly 251 and two rotating push rods 255b. The eccentric wheel 255a includes two circular sub-eccentric wheels 255c that are eccentrically positioned in opposite radial directions and stacked vertically. Each rotating push rod 255b includes a ring 255d rotatably fitted onto the corresponding sub-eccentric wheel and a push rod 255e extending outward from the ring 255d. The structure and working principle of the actuation component 255 of this embodiment are the same as those of the actuation component 226 of Embodiment 1, and will not be described in detail here.

[0106] Furthermore, it should be understood that the reciprocating motion of the clamping arms moving closer and further apart in this application is not limited to the reciprocating motion of the clamping arms 300 moving away from each other in only one dimension, as described in the above embodiments. Figure 5 The reciprocating motion shown can occur in one dimension (left-right), or it can occur in multiple dimensions, with components of reciprocating motion moving closer and further apart. For example... Figure 13 As shown, the clamping arm 301 of this embodiment (only one clamping arm is shown) includes a first clamping arm end 31, a second clamping arm end 35, and a clamping arm connecting portion 33 located between the first clamping arm end 31 and the second clamping arm end 35. The first clamping arm end 31 is built into the first flexible sleeve 400. The connecting portion 33 may be spherical, and the bracket 14 defines a corresponding partially spherical space so that the connecting portion 33 can slide along its arcuate surface therein. The second clamping arm end 35 is rotatably connected to the drive source 200, such as the connecting shaft 224c of the gear. Thus, under the drive of the drive source, the two opposing first clamping arm ends 31 will move in a circular trajectory, and the rotation directions of the two circles can be set to be symmetrical to each other, such as... Figure 14 As shown. At this time, the first clamping arm end 31 will also generate at... Figure 5 The reciprocating motion components moving towards and away from each other in the left and right directions can also achieve the same massage effect as the clamping arm 300. Therefore, the reciprocating motion of moving towards and away from each other mentioned in this application includes not only the clamping arm moving towards and away from each other, but also the reciprocating motion of the clamping arm's motion components moving towards and away from each other, both of which are within the inventive scope of this application.

[0107] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
