Description

Technical Field

[0001] The invention belongs to the technical field of massagers, relates to a technology for realizing sucking massage, and specifically relates to a sucking structure and a sucking massager. Background Art

[0002] A massager is a device that massages the human body through physical means. According to the different massage methods and techniques, the types of massagers can be mainly divided into the following categories:

[0003] Vibration massager: uses vibration or rotational motion to apply a certain amount of pressure to the human body, usually used to relieve muscle tension and relax the body, commonly seen in the neck, back and other parts.

[0004] Kneading massager: simulates the kneading action of fingers, and massages the muscles by rolling, pinching and twisting. It is often used in the shoulders, waist and other parts, and can help relieve muscle stiffness and pain.

[0005] Sucking massager: It uses the alternating changes of positive and negative air pressure to simulate the sucking action to attract and relax the skin surface. It is mainly used on the face, neck, shoulders, etc. Through the adjustment of airflow, it forms a sucking effect, achieving an effect similar to deep massage.

[0006] Although existing sucking massagers can simulate sucking action to a certain extent and provide airflow massage function, most sucking massagers in the current technology have the problem of limited positive and negative pressure changes. Existing sucking massagers can usually only provide a small range of air pressure changes, which leads to relatively weak massage effect and it is difficult to achieve strong suction and exhaust effects.

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] See also Figure 1-Figure 15 As shown, the specific embodiments provided by the present invention are as follows:

[0058] The present invention provides a sucking structure for performing sucking massage on a part of a human body to be massaged. Specifically, the structure simulates the effect of sucking massage by forming alternating positive and negative air pressure changes between the part of a human body to be massaged (such as the skin surface) and the device.

[0059] refer to Figures 1 to 4 , Fig. 9 As shown, the suction structure includes a static cavity 1, which is formed by a top wall A1, a side wall A2 and a bottom wall A3.

[0060] The top wall A1 is formed with an opening, which can be directly used to contact the part of the human body to be massaged, so as to be used as the airflow outlet 101 for airflow output and input. Alternatively, the opening is connected to an airflow member, and an opening is formed on the airflow member, which can be directly used to contact the part of the human body to be massaged, so as to be used as the airflow outlet 101 for airflow output and input.

[0061] The airflow member includes another cavity, which is referred to as the first cavity 102. The cavity formed by the top wall A1, the side wall A2 and the bottom wall A3 is referred to as the second cavity 103. The first cavity 102 and the second cavity 103 are connected through an airflow channel 104. The first cavity 102 is usually made of a flexible material to fit well to the part of the human body to be massaged.

[0062] The side wall A2 constitutes the side wall surface of the static cavity 1, and is used to connect the top wall A1 and the bottom wall A3, and constitute the second cavity 103 of the static cavity 1. Moreover, the second cavity 103 is in a relatively closed state.

[0063] The bottom wall A3 is provided with a first open end 105. The first open end 105 should be understood as having an opening formed by protruding and extending along its axial direction and in a direction away from the top wall A1. The first open end 105 is used to form an airflow connection with the dynamic cavity 2 described below.

[0064] In a specific embodiment, the top wall A1, the side wall A2 and the bottom wall A3 are all made of hard materials, that is, the static cavity 1 is made of hard materials as a whole.

[0065] In another specific embodiment, at least the side wall A2 and the bottom wall A3 are made of hard materials, and the top wall A1 is made of flexible material.

[0066] refer to Figures 4 to 5 As shown, the suction structure includes a dynamic chamber 2, and the dynamic chamber 2 has a linear movement along its axial direction. Specifically, the linear displacement of the dynamic chamber 2 is driven by a driving component 3. The driving mode can be in various forms, such as pneumatic drive, mechanical drive, electric drive, etc.

[0067] For the pneumatic drive form, the drive assembly 3 includes an air source device, which is the core part of providing pneumatic drive, and is usually composed of a compressed air source, an air pump or a gas cylinder. The air source device provides stable compressed gas, which is transmitted to the pneumatic control unit through a pipeline. The air source device can output and adjust the air flow pressure as needed to drive the dynamic cavity 2 to perform linear motion along a set trajectory.

[0068] The air source device is connected to the pressure regulator, and can adjust the intensity of the output air pressure as needed, thereby controlling the displacement speed and strength of the dynamic cavity 2.

[0069] The pneumatic piston is connected to the dynamic chamber 2, and the airflow enters the piston chamber through the air inlet, pushing the piston to move axially. The movement direction and amplitude of the pneumatic piston are controlled by the air pressure and the input of the airflow. Under the action of the airflow, the pneumatic piston produces a linear displacement in the dynamic chamber 2, causing the dynamic chamber 2 to translate along the specified axis.

[0070] The pneumatic control valve is responsible for regulating the inlet and outlet of the airflow and controlling the movement process of the dynamic chamber 2. The pneumatic control valve is usually composed of a solenoid valve or a mechanical valve, and controls the displacement direction and amplitude of the dynamic chamber 2 by accurately switching the airflow.

[0071] The control valve receives the command from the control system to decide whether to open the airflow channel 104. The pneumatic control valve can realize the forward or reverse flow of the airflow, so that the dynamic cavity 2 can move forward or backward, thereby simulating the effect of sucking.

[0072] When the pneumatic drive is started, the air source device (such as an air pump or a gas cylinder) delivers compressed air to the pneumatic control valve. The control valve decides whether to allow the air flow to enter the dynamic chamber 2 according to the system command, and controls the pressure and flow of the air flow.

[0073] After the compressed gas outputted by the gas source device flows into the piston cavity through the gas pipe and the gas flow channel, the piston generates a linear displacement in the cavity due to the effect of the gas flow pressure. This displacement drives the dynamic cavity 2 to translate in its axial direction.

[0074] The moving direction of the piston is determined by the direction of the airflow. When the airflow enters in the forward direction, the piston moves in one direction, pushing the dynamic chamber 2 forward along the specified trajectory; when the airflow enters in the reverse direction, the piston moves in the opposite direction, driving the dynamic chamber 2 to move in the reverse direction.

[0075] The pneumatic control valve adjusts the speed and periodic changes of the airflow by precisely controlling the input and discharge of the airflow, thereby affecting the movement of the dynamic chamber 2. Through the adjustment of the pneumatic control valve, the inflow of the airflow can be continuous or pulsed. The control valve can also change the direction of the airflow as needed to control the reverse movement of the pneumatic piston.

[0076] For the form of mechanical drive, the drive assembly 3 converts the rotary motion into linear motion through mechanical devices such as gears, slide rails or ball screws. The mechanical drive mode can usually provide a large torque and is suitable for application scenarios that require a large thrust.

[0077] For the electric drive form, the drive assembly 3 uses an electric motor or a stepper motor to drive the linear movement of the dynamic cavity 2, which can achieve precise positioning and adjustable movement speed.

[0078] In one specific implementation, a magnetic drive is used.

[0079] In a form of magnetic drive, a specific method of rotating magnetic pole drive is adopted, that is, a method of reversing the N / S pole direction by physically rotating any magnetic member. In this specific method, the driving assembly 3 is composed of a first magnetic member 301, a second magnetic member 302, and a rotating member 303. Through the interaction force between the first magnetic member 301 and the second magnetic member 302, combined with the rotational movement of the rotating member 303, the linear displacement of the dynamic cavity 2 can be effectively achieved.

[0080] refer to Figure 7 As shown, specifically, the first magnetic member 301 is arranged on the bottom wall B3 of the moving cavity 2. The magnetic pole of the first magnetic member 301 facing the second magnetic member 302 is the N pole or the S pole. The magnetic member interacts with the magnetic field of the second magnetic member 302 to provide a driving force to drive the linear displacement of the moving cavity 2.

[0081] The first magnetic member 301 is usually fixed on the moving cavity 2 to ensure the relative arrangement and magnetic field interaction between the first magnetic member 301 and the second magnetic member 302, thereby ensuring the effective transmission of magnetic force and generating sufficient attractive force or repulsive force to drive the moving cavity 2 to move.

[0082] The second magnetic member 302 is disposed on the opposite side of the first magnetic member 301, and the N pole and S pole of the magnetic member can be alternately reversed (such as flipped or rotated) toward the first magnetic member 301. By driving the second magnetic member 302 to flip or rotate, the mutual attraction or repulsion between the two can be changed.

[0083] The driving assembly 3 further includes a rotating member 303, which is connected to the second magnetic member 302. The rotating member 303 enables the second magnetic member 302 to perform a rotational motion, thereby driving the linear displacement of the dynamic cavity 2 through the change of magnetic force.

[0084] In a specific implementation, the rotating member 303 is usually composed of an electric motor, a stepper motor or other suitable driving elements. The rotating member 303 drives the magnetic pole of the second magnetic member 302 to change through rotational motion, thereby realizing dynamic magnetic pole reversal. This magnetic pole reversal mechanism can effectively adjust the attraction and repulsion between the two magnetic members, so that the dynamic cavity 2 can perform precise linear displacement along a set trajectory.

[0085] By rotating the rotating member 303, the magnetic pole of the second magnetic member 302 can alternate between the N pole and the S pole toward the first magnetic member 301. The change in the magnetic field after the reversal causes the interaction force between the first magnetic member 301 and the second magnetic member 302 to change, generating thrust or pull in different directions.

[0086] When the N pole of the second magnetic member 302 is connected with the N pole of the first magnetic member 301, a repulsive force is generated between them, pushing the movable cavity 2 away from the second magnetic member 302; when the N pole of the second magnetic member 302 is connected with the S pole of the first magnetic member 301, the magnetic field generates an attractive force, pushing the movable cavity 2 to move toward the second magnetic member 302. This alternating effect of attraction and repulsion enables the movable cavity 2 to perform linear displacement smoothly and accurately along its axial direction.

[0087] It should be noted that, in this embodiment, the first magnetic member 301 and the second magnetic member 302 should be ordinary magnets (referring to magnets made of permanent magnetic materials that can generate a magnetic field without an external power supply).

[0088] refer to Figure 8 As shown, in another form of magnetic drive, a specific method of electromagnetic drive is adopted, that is, a method of changing the magnetic pole of any magnetic component by electric current. In this specific method, the drive component 3 is composed of a first magnetic component 301, a second magnetic component 302, and an electric control component (not shown in the figure) for changing the magnetic pole state of any magnetic component. Through the magnetic interaction force between the first magnetic component 301 and the second magnetic component 302, combined with the adjustment of the magnetic pole of any magnetic component by the electric control component, the linear displacement control of the dynamic cavity 2 is achieved.

[0089] Specifically, the first magnetic member 301 is arranged on the top wall B1 of the moving cavity 2. The second magnetic member 302 is arranged on the bottom wall A3 of the static cavity 1, and the two are arranged opposite to each other. This symmetrical layout ensures that when the magnetic pole state changes, the attraction or repulsion between the first magnetic member 301 and the second magnetic member 302 can drive the moving cavity 2 to perform linear displacement.

[0090] It should be noted that, in this embodiment, the magnetic component whose magnetic polarity state is changed by the electronic control component should be an electromagnet.

[0091] Although the electronic control component is not shown in the figure, its function is to provide accurate commutation current to any magnetic component according to the control signal to achieve the conversion of the magnetic pole state.

[0092] In general, the driving component 3 realizes the linear displacement of the dynamic cavity 2 by controlling the reversal of the magnetic pole of any magnetic part (referring to rotating magnetic pole drive or electromagnetic drive). The attraction and repulsion between the magnetic parts act alternately to push the dynamic cavity 2 to move along its axial direction. This driving form has the advantages of non-contact, high precision, and rapid response, and can provide flexible and changeable massage experience according to different massage needs.

[0093] refer to Figure 7As shown, in a specific embodiment, a flexible structure 4 is provided between the first magnetic member 301 and the second magnetic member 302. The flexible structure 4 is intended to effectively absorb the vibration and impact caused by the change in magnetic force between the two magnetic members, thereby reducing the generation of noise. The flexible structure 4 not only provides elastic support, but also can ensure the smooth operation of the drive system through shock absorption and isolation functions, and improve the comfort and quietness during use.

[0094] Specifically, the rubber pad or rubber ring is used as the flexible structural part 4, mainly for shock absorption and absorption of vibration between magnetic parts. The rubber material has high elasticity and buffering performance, which can effectively isolate the direct contact between magnetic parts, reduce vibration transmission and absorb impact force, thereby significantly reducing the noise caused by the movement of magnetic parts.

[0095] The wear resistance and elasticity of rubber materials make it an ideal shock-absorbing and noise-suppressing material, which can effectively isolate mechanical noise caused by magnetic changes.

[0096] Alternatively, the flexible structure 4 uses an elastic film or elastic support sheet (such as polyurethane, silicone or other highly elastic materials) with good buffering performance, which can effectively absorb the vibration between the magnetic parts and reduce the impact, thereby reducing the noise during the operation of the system. By adjusting the thickness and material of the diaphragm, the optimal shock absorption effect can be provided for different magnetic force change frequencies.

[0097] The elastic membrane not only reduces impact, but also smoothes the relative movement of the magnetic parts, ensuring that the system can maintain a stable and quiet working state during high-speed movement.

[0098] refer to Figures 3 to 5 As shown, the dynamic chamber 2 is formed by a top wall B1, a side wall B2 and a bottom wall B3.

[0099] The top wall B1 has a second open end 201. It should be understood that the second open end 201 is an opening formed and extending along its axial direction and in a direction toward the first open end 105. The second open end 201 is used for docking with and separating from the first open end 105.

[0100] Specifically, as mentioned above, the dynamic cavity 2 has a linear motion along its axial direction. During this linear motion, the second opening end 201 moves toward or away from the first opening end 105. Correspondingly, the second opening end 201 and the first opening end 105 may be docked or separated.

[0101] When the two are butted together, the second open end 201 and the first open end 105 are joined to form a complete airflow channel, which connects the dynamic cavity 2 and the static cavity 1.

[0102] When the two are separated, the second open end 201 and the first open end 105 are disconnected, that is, the above-mentioned air flow channel is disconnected.

[0103] Among them, reference Fig. 9 As shown, the outer wall surface of the static cavity 1 should be understood to refer to all surfaces constituting the overall outer contour of the static cavity 1. The outer wall surface of the static cavity 1 should include the outer surface layer A11 of the top wall A1, the outer surface layer A21 of the side wall A2 and the outer surface layer A31 of the bottom wall A3.

[0104] Similarly, refer to Fig.10 As shown, the outer wall surface of the dynamic cavity 2 should be understood to refer to all surfaces constituting the overall outer contour of the dynamic cavity 2. The outer wall surface of the dynamic cavity 2 should include the outer surface layer B11 of the top wall B1, the outer surface layer B21 of the side wall B2 and the outer surface layer B31 of the bottom wall B3.

[0105] Based on this, reference Figures 4 to 5 , Figures 9 to 12 As shown, the suction structure includes a flexible connecting wall 501. The flexible connecting wall 501 connects the static cavity 1 and the dynamic cavity 2 and is located between the two.

[0106] refer to Fig.11 As shown, in a specific implementation of the present embodiment, the flexible connecting wall 501 is connected between the bottom wall A3 of the static cavity 1 and the bottom wall B3 of the dynamic cavity 2, and the variable volume cavity 502 should be formed by the inner wall surface of the flexible connecting wall 501, the partial outer wall surface of the static cavity 1 (referring to the outer surface A31 of the bottom wall A3) and the partial outer wall surface of the dynamic cavity 2 (referring to the outer surface B11 of the top wall B1).

[0107] refer to Fig.12 As shown, in another implementation of the present embodiment, the flexible connecting wall 501 is connected between the side wall A2 of the static cavity 1 and the side wall B2 of the dynamic cavity 2, and the variable volume cavity 502 should be composed of the inner wall surface of the flexible connecting wall 501, the partial outer wall surface of the static cavity 1 (referring to the outer surface A21 of the side wall A2 and the outer surface A31 of the bottom wall A3), and the partial outer wall surface of the dynamic cavity 2 (the outer surface B21 of the side wall B2 and the outer surface B11 of the top wall B1).

[0108] Therefore, the local outer wall surface of the static cavity 1 and the dynamic cavity 2 refers to the specific area of ​​the overall outer wall surface that participates in enclosing the variable volume cavity 502 due to structural design requirements.

[0109] In general, the inner wall surface of the flexible connecting wall 501, the partial outer wall surface of the static cavity 1 and the partial outer wall surface of the dynamic cavity 2 enclose a closed variable volume cavity 502, and the first opening end 105 and the second opening end 201 are both located inside the variable volume cavity 502. The variable volume cavity 502 plays an important role in the linear motion of the dynamic cavity 2. Specifically, when the dynamic cavity 2 moves linearly along the axial direction, the first opening end 105 and the second opening end 201 will dock or separate. This motion process causes the state of the variable volume cavity 502 to change, thereby participating in the regulation of air pressure changes.

[0110] refer to Figure 5 As shown, when the first open end 105 and the second open end 201 are docked, the two form an airflow channel to separate the variable volume cavity 502 from the dynamic cavity 2 and the static cavity 1. During the docking process, the gas in the variable volume cavity 502 will gradually be compressed and enter the dynamic cavity 2 and the static cavity 1, thereby forming a positive pressure state. Positive pressure refers to the process of airflow output from the inside to the external environment, which drives the external air flow.

[0111] refer to Figure 4 As shown, when the first opening end 105 and the second opening end 201 are separated, the variable volume cavity 502 gradually communicates with the dynamic cavity 2 and the static cavity 1, so that the three together serve as airflow input into the cavity, inhaling a large amount of gas, thereby forming a negative pressure state. Negative pressure refers to the process of airflow flowing from the external environment into the interior, producing a suction effect.

[0112] That is to say, the variable volume cavity 502 participates in the generation of positive and negative air pressure by connecting and separating with the air flow channel between the dynamic cavity 2 and the static cavity 1. The change of its volume not only affects the distribution of air pressure, but also adjusts the air pressure environment of the massage area, thereby enhancing the adjustability and flexibility of the massage effect.

[0113] In general, the role played by the variable volume cavity 502 in the process of airflow inhalation and output significantly improves the effects of negative pressure and positive pressure, thereby optimizing the massage experience.

[0114] In the process of air inhalation, the participation of the variable volume cavity 502 significantly increases the space of the air input cavity. When the dynamic cavity 2 is connected with the static cavity 1 and the variable volume cavity 502, the variable volume cavity 502 effectively expands the space for gas storage, greatly increasing the amount of inhaled gas, thereby producing a more significant negative pressure effect. The negative pressure effect can not only penetrate deeper into the skin layer and muscle tissue, but also enhance the attraction effect, simulate a stronger sucking effect, and significantly improve the depth and comfort of massage.

[0115] In the process of airflow output, the gradual division of the variable volume cavity 502 significantly reduces the space used for compressed gas. As the gas in the variable volume cavity 502 is gradually compressed and discharged, the reduction of the compressed space makes the gas discharge more concentrated, thereby enhancing the positive pressure effect of the airflow. The positive pressure effect can effectively promote the flow of external air, bring a stronger exhaust effect, promote blood circulation and improve the comfort of the massage area.

[0116] In summary, the present invention significantly improves the variation range of positive and negative air pressures through the regulation of the variable volume cavity 502, providing a stronger massage effect than the traditional technology. The dynamic regulation of the variable volume cavity 502 in the positive and negative air pressure process can simulate a stronger sucking massage, meeting the user's needs for deep relaxation and comfortable massage.

[0117] In a specific embodiment, the flexible connecting wall 501 is made of polyurethane (PU) or silicone material with good elasticity and durability. These materials can not only provide sufficient flexibility to cope with the volume change of the variable volume cavity 502, but also have strong pressure resistance and anti-aging performance, ensuring that it will not fail due to repeated deformation during long-term use.

[0118] In addition, polyurethane and silicone materials have a lower coefficient of friction, which can reduce wear during exercise and improve the stability and comfort of the system.

[0119] In a specific embodiment, the thickness of the flexible connecting wall 501 is generally between 1 and 5 mm, which is adjusted according to the specific requirements of the system. The thin-walled structure can ensure that the flexible connecting wall 501 has sufficient elasticity to adapt to the volume change of the variable volume cavity 502, while providing effective sealing.

[0120] The material within this thickness range can withstand greater stress and pressure fluctuations when the volume of the variable volume cavity 502 changes, and can quickly return to the original state, ensuring efficient operation of the system.

[0121] The side wall B2 of the dynamic chamber 2 connects the surrounding top wall B1 and the bottom wall B3. Generally speaking, the dynamic chamber 2 is a relatively closed cavity.

[0122] The bottom wall B3 of the dynamic chamber 2 is usually not provided with any openings. That is, the dynamic chamber 2 has only one second opening end 201 to ensure a significant effect on the airflow change.

[0123] In a specific embodiment, the top wall B1, the side wall B2 and the bottom wall B3 of the dynamic chamber 2 are all made of hard materials, that is, the dynamic chamber 2 is made of hard materials as a whole.

[0124] In a specific embodiment, the ports of the first opening end 105 and the second opening end 201 are both provided with a flexible material layer 6. Specifically, the ports of the first opening end 105 and the second opening end 201 are both covered with a layer of flexible material. For example, the edges of the ports of the first opening end 105 and the second opening end 201 are provided with an embedding groove with a depth of 1.5-2 mm, and the bottom of the flexible material layer 6 has a T-shaped reinforcement rib, which is stably fixed after embedding. Alternatively, the flexible material layer 6 is a U-shaped or C-shaped flexible covering sleeve, which is buckled on the edge of the port and fixed by using the material's resilience.

[0125] The flexible material layer 6 is mainly used to provide a better sealing effect to ensure that the airflow channel does not leak during the docking or separation process; at the same time, the use of flexible materials can also reduce noise.

[0126] In one embodiment, the number of the static cavity 1 is 1, and the number of the dynamic cavity 2 is 1.

[0127] In another embodiment, the number of static cavities 1 is 1, and the number of dynamic cavities 2 is plural, which may be 2, 3, 4 or more. The multiple dynamic cavities 2 are rigidly connected to form an integral structure, and the dynamic cavities 2 are connected in this way. Specifically, the multiple dynamic cavities 2 together constitute a structural unit that can move linearly along the axial direction. For example, when the number of dynamic cavities 2 is 2, a communication port is provided on the bottom wall B3 of the first dynamic cavity 2 (referring to the dynamic cavity 2 close to the static cavity 1), and a communication port is provided at a corresponding position on the top wall B1 of the second dynamic cavity 2 (referring to the dynamic cavity 2 far away from the static cavity 1), and the aforementioned two communication ports can be connected by a tubular channel made of hard material.

[0128] In this embodiment, the connection between the dynamic chambers 2 is achieved by a rigid connection, ensuring that the multiple dynamic chambers 2 can move in coordination as a whole under the action of the airflow. The axial movement of each dynamic chamber 2 is limited by the overall structure, and the connectivity between the dynamic chambers 2 ensures the stability of the airflow channel and allows the airflow to flow smoothly between the multiple dynamic chambers 2.

[0129] Through the rigid connection, the multiple dynamic cavities 2 can maintain a consistent motion trajectory as a whole, forming a stable airflow change field during the docking or separation process.

[0130] refer to Figures 13 to 15 As shown, a sucking massager is provided, which includes the sucking structure mentioned above.

[0131] The massager further comprises a housing 7. Generally speaking, the housing 7 comprises an internal hard housing 7 and a silicone housing 7 coated on the hard housing 7. The suction structure is arranged inside the hard housing 7.

[0132] An opening is formed on the wall surface of the housing 7 , and the opening is used to connect or expose the air flow opening 101 of the suction structure.

[0133] Among them, the sucking massager includes a control system that can adjust the airflow intensity, allowing users to adjust the amplitude of positive and negative pressure changes according to their own comfort, increasing the flexibility of the product and the user's customized experience.

[0134] In some embodiments, the control system includes an easy-to-operate control interface, which is usually located on the handle or housing 7 of the massager, and the user can make adjustments through buttons, knobs, or a touch screen.

[0135] On the control interface, users can select different airflow intensity levels or modes, usually including several gears (for example: low, medium, high, etc.), or precisely adjust the intensity of the airflow output as needed.

[0136] Furthermore, users can use the control system to adjust the positive and negative pressure changes of the airflow. For example:

[0137] Positive pressure mode: airflow is output from the inside of the massager to the external environment, helping to promote blood circulation and relieve muscle tension.

[0138] Negative pressure mode: air is sucked from the external environment into the massager, creating an adsorption effect that mimics a sucking massage and delivers a deep relaxing effect.

[0139] In each mode, users can adjust the intensity of the airflow according to their personal preferences, control the strength and frequency of the airflow output, making the massage process more personalized and comfortable.

[0140] Alternatively, the control system allows the massager to automatically adjust the airflow intensity based on user feedback. For example, through the built-in pressure sensor, the device can sense the contact pressure of the skin during massage and intelligently adjust the airflow intensity to ensure that the massage effect is both comfortable and efficient.

[0141] This intelligent adjustment function can also be combined with automatic time control, such as automatically changing the airflow intensity according to the set time during use to simulate different massage rhythms.

[0142] More specifically, the control system can provide different massage modes, such as:

[0143] Gentle mode: Low-intensity airflow, suitable for first-time users or users who need a gentle massage.

[0144] Deep mode: High-intensity airflow, suitable for relieving deep muscle tension or promoting deep blood circulation.

[0145] Pulse mode: Alternating positive and negative pressure modes help accelerate blood circulation and relax muscles, increasing the stimulation and effect of massage.

[0146] Each mode can be fine-tuned according to actual needs to ensure appropriate strength and effect during massage.

[0147] In some embodiments, the control system may also have a real-time feedback function, such as informing the user of the current airflow intensity, mode, and remaining usage time through a display screen, indicator light, or audio prompt, so that the user can control the massage process in real time.
