Description

Technical Field

[0001] This invention relates to the field of eye massage device technology, and more particularly to a dual-point eye massage device with an air bag linkage pressing component. Background Technology

[0002] Eye massage devices have been widely used to relieve eye fatigue, improve blood circulation in the eyes, and relax the mind and body. Most existing pneumatic eye massage devices use the expansion force generated by the inflation and deflation of airbags to press around the eyes.

[0003] A search revealed the following shortcomings in the existing technology: First, to achieve massage of multiple points such as the eye socket and temples, the common solution is to set up multiple isolated air bags. Each air bag is controlled by an independent solenoid valve to control the inflation and deflation sequence. This solution requires multiple solenoid valves and a complex air circuit layout, resulting in high product cost, large size, and increased failure rate. In addition, there is no mechanical linkage between the air bags, and the massage action depends entirely on the electronic control program.

[0004] Secondly, the massage methods are monotonous. In existing airbag massage devices, the airbag inflation is limited to vertical pressure, which cannot achieve lifting of the skin at the corners of the eyes or kneading and pushing of the temples. The massage experience is relatively monotonous and differs from the kneading and lifting techniques of manual massage.

[0005] Third, the aromatherapy function lacks mechanical linkage with the massage movements, resulting in low utilization of essential oils. Some eye massage devices have added aromatherapy modules, but the aromatherapy release usually adopts an independent air pump diversion blowing or natural evaporation method, which has no direct mechanical coupling relationship with the massage movements. The aromatherapy essential oils continue to evaporate even when not in a massage state, resulting in waste and a short effective lifespan.

[0006] Fourth, existing linkage structures lack precise control and adjustable design for the rotation angle of the massage rollers, making it unable to adapt to the varying tolerance levels of different users. Therefore, a dual-point eye massage device with an airbag linkage pressing component is needed to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to solve the problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A dual-point eye massager with an airbag-linked pressure component includes: An eye massage device, comprising a device housing that serves as the overall frame of the device; The active massage area includes two airbag components, which are installed inside the device housing via a gourd-shaped groove. The surface of the gourd-shaped groove of the device housing is covered with a curtain, and the surface of the curtain has holes and slots for the airbag components to expand and deform. The inner sides of the back of the two airbag components are connected and penetrated by a connecting pipe. The top of the middle section of the connecting pipe is connected to an air inlet pipe, and the end of the air inlet pipe passes through the top of the device housing and connects to an external interface. The surface of the air inlet pipe is also provided with a miniature air pump and a solenoid valve module assembly for switching on and off the air discharge. The linkage massage part is located on both sides inside the device shell near the air bag component. The linkage massage part includes a volute massage wheel.

The essential oil sealing plate is fixed to the inner wall of the fragrance cartridge. A lower sealing assembly is threaded into the bottom of the fragrance cartridge, and a diffuser sponge for absorbing fragrance essential oil is placed between the lower sealing assembly and the essential oil sealing plate. Airflow hoses are located on the left and right sides of the bottom of the fragrance cartridge, and these airflow hoses are inserted into the device housing through fragrance holes, with the fragrance hole outlet located inside the nose pad area of ​​the device housing.

[0009] Preferably, the air bag component includes a pressing air bag that is connected to both ends of the connecting tube, and the pressing air bag has thickened spherical protrusions arranged around its surface for pressing the user's eye sockets; The surface of the press air bag has a thin ring portion with a relatively thin layer, and the center of the surface of the press air bag is also provided with a thickened central protrusion for massage.

[0010] Preferably, the volute massage wheel has a groove inside, and a short arm is movably installed on the side of the groove. A curved arm is movably connected to the end of the short arm, and a silicone edging is connected to the other end of the curved arm. The silicone edging is fixed to the side of the press air bag. When the air bag is inflated by pressing, it expands and moves outward along the groove of the curtain and along the movable groove of the device casing. As the air bag expands along the movable groove of the device casing, it pushes the curved arm and controls the volute massage wheel to rotate within a small range.

[0011] Preferably, a positioning block is provided at the junction of the end surface of the crank arm and the short arm, and the positioning block is engaged with the surface of the short arm through a groove, thereby limiting the maximum movable tilt angle of the short arm and the crank arm.

[0012] Preferably, a return spring A is connected to the back of the short arm, and the back of the return spring A is fixed in the movable groove of the equipment housing for restoring support of the short arm.

[0013] Preferably, the airbag assembly includes a compression bladder placed inside the fragrance tube, and a pneumatic tube is connected to the left side of the top of the compression bladder. After the pneumatic tube passes through the fragrance tube, its end is connected to a connecting air nozzle. The connecting air nozzle is installed on the inner end of the pressing air bag. The pneumatic tube is also equipped with a solenoid valve assembly.

[0014] Preferably, the push assembly includes a tray frame fixed to the inner wall of the fragrance tube, and a central shaft is inserted through a through hole at the center of the tray frame. A top plate is connected to the top of the central shaft, and a return spring B is sleeved on the surface of the central shaft. The upper and lower ends of the return spring B are respectively connected and fixed to the top plate and the inner end of the tray frame. A piston head is connected to the bottom of the central shaft, and a sealing ring is sleeved on the surface of the piston head through an annular groove. The outer side of the sealing ring abuts against the inner wall of the fragrance tube for sealing. An essential oil cavity is provided between the bottom of the piston head and the essential oil sealing plate.

[0015] Preferably, the surface of the essential oil sealing plate is provided with essential oil drip holes for essential oil to drip after air pressure is applied.

[0016] Preferably, the lower sealing assembly includes a threaded bottom cover, which is threadedly inserted into the bottom end of the fragrance tube, thereby sealing the bottom of the fragrance tube; The top edge of the threaded bottom cover is connected to the hollowed-out plate via several support plates, and a fragrance diffuser is formed between the hollowed-out plate and the threaded bottom cover. The air diffuser tube is connected to the surface of the fragrance tube and communicates with the fragrance diffuser.

[0017] Preferably, the atmosphere hose is provided with a check membrane to prevent dust from entering the fragrance cylinder in the reverse direction.

[0018] This invention has at least the following beneficial effects: 1. This invention utilizes a miniature air pump and a solenoid valve module assembly to simultaneously inflate two pressing air bags through an air inlet pipe and a connecting pipe. The mechanical thrust generated by the expansion of the pressing air bags simultaneously drives three sets of actions: eye socket pressing, eye corner lifting, and aromatherapy release. One air source and one inflation action complete three functional outputs. There is no need to set up a separate air pump or solenoid valve for aromatherapy, which greatly simplifies the air circuit and electronic control system, and reduces costs and failure rates.

[0019] 2. This invention uses a snail-shaped massage wheel that rotates around a movable axis under the drive of the curved and short arms. Its snail-shaped protrusion first presses the corner of the eye, and as the rotation angle increases, it slides towards the temple and generates an upward lifting force. This compound action simulates the manual kneading and lifting techniques, which is different from the single vertical pressing of existing airbags. It significantly improves the comfort and effect of massage and enriches the massage experience.

[0020] 3. The invention achieves this by pressing the air bag to inflate it more fully, resulting in higher internal air pressure. This leads to greater pressing force and higher air pressure transmitted to the compression bladder through the pneumatic tube. Consequently, the piston head is pushed downward to compress the essential oil chamber, resulting in more essential oil dripping from the essential oil sealing plate and a stronger aroma. This creates a positive feedback synergistic effect mechanism where the more forceful the massage, the stronger the aroma.

[0021] 4. In this invention, the essential oil is only squeezed out and drips when the air bag is inflated and the air pressure acts on the piston head. After the air is released, the return spring B pushes the piston head back to its original position, the air pressure in the essential oil chamber returns to normal pressure, the essential oil stops dripping, the aroma release and massage action are precisely synchronized, there is no consumption of essential oil when not massaging, effectively extending the life of a single filling of essential oil and reducing user costs.

[0022] 5. The press air bag of this invention adopts a differentiated thickness design: the thickened spherical protrusion and the thickened central protrusion have a larger wall thickness to form hard protrusions, which apply concentrated pressure to the edge and central area of ​​the orbital bone. The thin ring part has a thinner wall thickness and expands first to form a ring-shaped depression. One inflation achieves the dual effect of ring wrapping and point strong pressure, which is in line with the concept of combining point and surface in traditional Chinese medicine acupoint massage.

[0023] 6. The sealing ring on the piston head of this invention ensures that the essential oil chamber is sealed and isolated from the upper air passage, preventing essential oil from entering the pneumatic tube. The check membrane inside the air hose prevents outside air and dust from entering the fragrance cartridge in reverse, avoiding contamination and deterioration of the essential oil. The filling port is equipped with a sealing plug, which facilitates the replenishment of essential oil while maintaining the system seal, ensuring hygienic and safe use. Attached Figure Description

[0038] The device will be analyzed and described below through several embodiments to aid understanding; Example 1; The typical usage scenario is office workers taking a lunch break or relaxing before bed. The user wears the eye massage device 1 on their head, with the inner side of the device shell 11 fitting against the face. The two air bags 21 are positioned at the eye sockets of the left and right eyes, respectively. The worm-shell massage roller 35 is located on the outer corner of the eye, corresponding to the area from the corner of the eye to the temple. The outlet of the air hose 48 is located inside the nose pad, close to the user's nostrils.

[0039] The outer casing 11 serves as the overall frame, with a gourd-shaped groove on its inner side corresponding to the eye socket position. The shape and size of the gourd-shaped groove match the outer contour of the air bag component 21. Two air bag components 21 are embedded in the gourd-shaped groove, and the surface of the gourd-shaped groove is covered with a curtain 12. The curtain 12 is fixed to the inner side of the outer casing 11 by sewing or gluing. The surface of the curtain 12 has holes and slots, the position and size of which correspond to the expansion direction of the press air bag 211, allowing the press air bag 211 to protrude towards the human eye socket when inflated. At the same time, the curtain 12 limits and protects other parts of the air bag component 21.

[0040] Two airbag components 21 are arranged side by side, corresponding to the left and right eyes respectively. Each airbag component 21 includes a press airbag 211. The press airbag 211 is made of a flexible airtight material, such as medical-grade silicone or TPU. The inner sides of the back of the two press airbags 211 are connected to each other through a connecting tube 22. The connecting tube 22 is a flexible hose that allows the air pressure of the two press airbags 211 to be consistent. The middle section of the connecting tube 22 is connected to an air inlet tube 23. The air inlet tube 23 extends upward from the connecting tube 22, passes through a through hole at the top of the device housing 11, and has an external interface at the end for connection with an external air source. The surface of the air inlet tube 23 is provided with a miniature air pump and a solenoid valve module assembly 24. This module assembly is integrated and installed inside or on the outer surface of the device housing 11 to control the inflation and deflation of the air inlet tube 23.

[0041] The surface structure of the press air bag 211 adopts a differentiated thickness design: thickened spherical protrusions 214 are arranged around its surface edges. The wall thickness of the thickened spherical protrusions 214 is greater than the wall thickness of the main body of the press air bag 211. After inflation, it forms obvious spherical protrusions, which are used to apply point-like pressure to the edge of the orbital bone. A thickened central protrusion 212 is provided at the center of the surface of the press air bag 211 for concentrated pressure on the eye socket area directly above the eyeball; a thin ring portion 213 is provided on the surface of the press air bag 211, the wall thickness of which is less than the main wall thickness of the press air bag 211. When inflated, it expands first to form a ring-shaped depression, making the thickened spherical protrusion 214 and the thickened central protrusion 212 relatively prominent, enhancing the sense of layering of the press.

[0042] The linked massage parts 3 are located on both sides inside the device housing 11. Each air bag component 21 has a corresponding set of linked massage parts 3 on its outer side. The silicone edging 31 is made of elastic silicone material.

The connection between the curved arm 32 and the short arm 33 is hinged, allowing them to rotate relative to each other within a certain angle range.

[0043] The end of the short arm 33 is movably mounted on the side of a groove inside the volute massage wheel 35, and the short arm 33 and the volute massage wheel 35 are hinged together. The volute massage wheel 35 is shaped like a snail shell, with snail-shaped protrusions, i.e., spiral ridges, on its outer periphery. Movable shafts 37 are located at the center of both sides of the volute massage wheel 35. The movable shafts 37 are integrally formed with or fixedly connected to the volute massage wheel 35. The movable shafts 37 are rotatably mounted in a movable groove in the device housing 11. The movable groove is an arc-shaped or circular groove formed on the inner wall of the device housing 11, allowing the movable shafts 37 to rotate freely within it. An elastic strip 13 is installed inside the movable groove, covering the outer surface of the volute massage wheel 35, providing coverage and protection, while allowing the protrusions of the volute massage wheel 35 to apply pressure to the skin through the elastic strip 13.

[0044] A positioning block 34 is provided at the hinge position of the curved arm 32 and the short arm 33. The positioning block 34 is engaged with the surface of the short arm 33 through a groove. The geometry of the positioning block 34 is configured such that when the included angle between the curved arm 32 and the short arm 33 increases to a preset maximum value, the positioning block 34 forms an abutment contact with the end surface of the curved arm 32 or the side wall of the short arm 33, thereby limiting the further extension of the curved arm 32 and the short arm 33, that is, limiting the maximum movable tilt angle between them. A return spring A36 is connected to the back of the short arm 33. One end of the return spring A36 is fixedly connected to the short arm 33, and the other end is fixed to the inner wall of the movable groove of the equipment housing 11.

[0045] The soothing part 4 is located in the center or one side of the internal space of the device housing 11. The fragrance tube 41 is cylindrical, with a retaining plate on its outer wall. A slot is provided in the corresponding position inside the device housing 11.

Rotating the threaded top cover 42 can open or close the fragrance tube 41.

[0046] The airbag assembly 43 is located in the upper area inside the fragrance cylinder 41. The compression bladder 431 is a compressible elastic airbag placed inside the fragrance cylinder 41. A pneumatic tube 432 is connected to the top left of the compression bladder 431. The pneumatic tube 432 extends outward after passing through the side wall of the fragrance cylinder 41, and its end is connected to the connecting nozzle 215. The connecting nozzle 215 is installed on the inner end of the pressing air bag 211, that is, the side of the two pressing air bags 211 facing each other. The connecting nozzle 215 is connected to the internal air chamber of the pressing air bag 211. A solenoid valve assembly 433 is provided on the pneumatic tube 432. The solenoid valve assembly 433 is fixedly installed inside the device housing 11 or outside the fragrance cylinder 41 to control the opening and closing of the pneumatic tube 432.

[0047] The push assembly 44 is positioned below the airbag assembly 43. The disc holder 442 is a disc-shaped support, its outer edge fixed to the inner wall of the fragrance cylinder 41 by adhesive or snap-fit. A through hole is provided at the center of the disc holder 442, through which the central shaft 443 passes from top to bottom. The central shaft 443 and the through hole are in clearance fit, allowing the central shaft 443 to slide up and down axially. A top plate 441 is fixedly connected to the top of the central shaft 443, which is located above the disc holder 442 and directly opposite the bottom of the compression bladder 431. A return spring B444 is fitted on the surface of the central shaft 443. The upper end of the return spring B444 abuts against or is fixedly connected to the lower end face of the top plate 441, and the lower end of the return spring B444 abuts against or is fixedly connected to the upper end face of the disc holder 442. A piston head 445 is fixedly connected to the bottom end of the central shaft 443. The piston head 445 is a cylinder, and its outer diameter matches the inner diameter of the fragrance cylinder 41. An annular groove is formed on the surface of the piston head 445, and a sealing ring 446 is fitted inside the annular groove. The outer wall of the sealing ring 446 forms an interference fit with the inner wall of the fragrance cylinder 41 to prevent gas or liquid from leaking from the gap between the piston head 445 and the inner wall of the fragrance cylinder 41.

[0048] Below the piston head 445 is an essential oil sealing plate 45, which is disc-shaped and its outer edge is fixed to the inner wall of the fragrance cylinder 41 by bonding or integral molding. Located below the piston head 445, the space between the bottom surface of the piston head 445 and the top surface of the essential oil sealing plate 45 forms an essential oil chamber, which stores liquid aromatherapy essential oil. The surface of the essential oil sealing plate 45 has essential oil drip holes, which are small through holes that allow the essential oil to drip slowly under air pressure. For convenient refilling of essential oil, a filling port is provided on the side wall of the fragrance cylinder 41 corresponding to the essential oil chamber. The filling port is equipped with a sealing plug, allowing the user to add essential oil to the essential oil chamber through the filling port.

[0049] The bottom end of the fragrance tube 41 is threadedly connected to a lower sealing assembly 47, which includes a threaded bottom cover 471. The outer edge of the threaded bottom cover 471 has external threads that mate with the internal threads on the inner wall of the bottom end of the fragrance tube 41. By rotating, the threaded bottom cover 471 is detachably fixed to the bottom of the fragrance tube 41. The top edge of the threaded bottom cover 471 is fixedly connected to a perforated disc 473 by several support plates 472 evenly distributed around the circumference. The perforated disc 473 is disc-shaped and has multiple through holes on its surface to allow gas to pass through. A diffuser cavity is formed between the diffuser and the threaded bottom cover 471. The diffuser sponge 46 is located between the lower sealing assembly 47 and the essential oil sealing plate 45, specifically below the essential oil sealing plate 45 and above the hollowed-out disc 473. The diffuser sponge 46 is a porous sponge with the ability to absorb and retain liquid. A gap is maintained between the top surface of the diffuser sponge 46 and the bottom surface of the essential oil sealing plate 45. This gap allows the essential oil dripping from the essential oil drip hole to fall freely into the surface of the diffuser sponge 46, avoiding direct contact between the essential oil sealing plate 45 and the diffuser sponge 46, which could cause blockage.

[0050] At the bottom left and right sides of the fragrance tube 41, at the corresponding height of the diffuser chamber, there are atmosphere hoses 48. One end of the atmosphere hose 48 is connected to the diffuser chamber, and the other end is inserted into the fragrance hole inside the device housing 11. The outlet of the fragrance hole is located inside the nose pad of the device housing 11, that is, the area close to the user's nostrils when worn. The atmosphere hose 48 is equipped with a check membrane. The check membrane is a one-way valve structure that allows gas to flow from the fragrance tube 41 to the nose pad outlet, but prevents outside air or dust from entering the fragrance tube 41 in reverse.

[0051] Working principle: First, the user puts on the eye massage device 1 and turns on the power. The micro air pump in the micro air pump and solenoid valve module assembly 24 starts to work, and simultaneously inflates the two pressing air bags 211 through the air inlet pipe 23 and the connecting pipe 22, and the air pressure inside the pressing air bags 211 gradually increases.

[0052] Secondly, the air bag 211 is inflated by pressing. Since the surface of the curtain 12 has grooves, the inflation direction of the air bag 211 is guided to protrude towards the eye socket. During the inflation process, the thickened spherical protrusion 214 and the thickened central protrusion 212 have relatively small expansion amplitude due to their larger wall thickness, forming hard protrusions that apply concentrated pressure to the edge of the eye socket bone and the central area of ​​the eye socket, thus achieving the first point of eye socket pressure. The thin ring part 213 has a thinner wall thickness and expands first, forming a ring-shaped depression area, making the thickened protrusions relatively prominent, enhancing the sense of layering and the acupoint targeting of the pressure.

[0053] Simultaneously, as the airbag 211 inflates, its outer side expands outward. The silicone edging 31 fixed to the side of the airbag 211 moves outward accordingly, pushing the curved arm 32 to move away from the airbag 211. The movement of the curved arm 32 causes the short arm 33, which is hinged to it, to swing. The swing of the short arm 33 drives the volute massage wheel 35 to rotate around the movable shaft 37 in a small range. When the volute massage wheel 35 rotates, its snail-shaped protrusion gradually contacts the skin from the corner of the eye to the temple, first pressing the corner of the eye. Then, as the rotation angle increases, the snail-shaped protrusion slides towards the temple and generates an upward lifting force, realizing a second point of combined pressing and lifting massage from the corner of the eye to the temple.

[0054] During the swinging of the short arm 33, the positioning block 34 limits the maximum angle between the curved arm 32 and the short arm 33 to prevent the short arm 33 from swinging excessively due to excessive inflation pressure and the volute massage wheel 35 from rotating too much, causing discomfort to the user. The return spring A36 is stretched or compressed when the short arm 33 swings, storing elastic potential energy.

[0055] Simultaneously, in sync with the aforementioned massage action, when the air bag 211 is inflated, its internal air pressure is output through the connecting air nozzle 215. Under the action of the control signal, the solenoid valve group 433 opens the passage of the pneumatic tube 432, and the air pressure is transmitted to the compression bladder 431 through the pneumatic tube 432. The compression bladder 431 inflates and expands, and its bottom pushes the top plate 441 downward. The top plate 441 overcomes the elastic force of the return spring B444, driving the central shaft 443 and the piston head 445 to move downward. When the piston head 445 moves downward, it compresses the air in the essential oil chamber below it, causing the air pressure in the essential oil chamber to rise. This air pressure acts on the essential oil on the upper surface of the essential oil sealing plate 45, pressing the essential oil downward through the essential oil drip hole. The essential oil drips in droplets onto the diffuser sponge 46. After the diffuser sponge 46 absorbs the essential oil, the essential oil naturally evaporates at room temperature, and the resulting aroma fills the diffuser chamber.

[0056] Then, driven by the concentration difference, the aromatic gas in the diffuser chamber naturally diffuses through the atmosphere hose 48 to the outlet inside the nose pad of the device housing 11, where it is inhaled by the user. The check valve prevents the airflow from flowing back into the aroma diffuser 41 when the user exhales.

[0057] Finally, after the pressure holding time set in the massage program ends, the solenoid valve in the micro air pump and solenoid valve module assembly 24 switches to the exhaust state, the gas in the press air bag 211 is discharged through the air inlet pipe 23, the press air bag 211 contracts, and when the press air bag 211 contracts: The thickened spherical protrusion 214 and the thickened central protrusion 212 retract, relieving pressure on the eye socket; The silicone edging 31 returns to its original position as the air bag 211 is pressed. The curved arm 32 and the short arm 33 return to their initial positions under the elastic force of the return spring A36. The volute massage wheel 35 rotates back to its original position in the opposite direction, and the pressing and lifting from the corner of the eye to the temple is released. Pressing the air bag 211 reduces the internal air pressure, causing the compression bladder 431 to contract. The return spring B444 pushes the top plate 441, central shaft 443, and piston head 445 upwards to return to their original positions. The air pressure in the essential oil chamber returns to normal, the essential oil stops dripping, and the aromatherapy release automatically stops.

[0058] A complete massage cycle typically consists of: 3-5 seconds of inflation followed by massage and aromatherapy release, 2-4 seconds of pressure maintenance, and 2-3 seconds of decompression for resetting.

[0059] Regarding the connection method between the silicone edging 31 and the press-fit air bag 211: The silicone edging 31 can be fixedly connected to the press-fit air bag 211 by secondary injection molding or medical-grade adhesive bonding. In order to prevent the connection from falling off during repeated inflation and deflation, a groove or anchor point structure can be preset on the side of the press-fit air bag 211, and the silicone edging 31 is embedded in the groove and vulcanized.

[0060] Regarding the sealing of the connection between the air nozzle 215 and the pneumatic tube 432: a sealing ring or a tapered fit should be used at the joint between the air nozzle 215 and the pneumatic tube 432 to ensure that there is no air leakage during the pressurization of the air bag 211. The solenoid valve group 433 should be a normally closed two-position two-way solenoid valve, which will automatically cut off the air path when power is lost to prevent the aromatherapy from continuing to be released after the massage ends.

[0061] Regarding the sealing and filling of the essential oil chamber: a sealant should be applied or a sealing ring should be installed between the essential oil sealing plate 45 and the inner wall of the fragrance tube 41 to prevent essential oil from leaking from the side wall. The filling port should be located on the outer wall of the fragrance tube 41 at the height of the essential oil chamber. The inner diameter of the filling port can be 3-5mm and equipped with a silicone sealing plug. When filling or replenishing essential oil for the first time, the user needs to remove the threaded top cover 42, press the top plate 441 to make the piston head 445 move down to the lowest position, so that the essential oil chamber is in the minimum volume state. Then, inject essential oil through the filling port to the preset liquid level. The liquid level should not exceed 2 / 3 of the height of the essential oil chamber to leave space for the piston head 445 to move down.

[0062] Regarding the selection and replacement of diffuser sponge 46: High-density polyurethane sponge or cellulose sponge is preferred for diffuser sponge 46. The recommended pore size is 60-90ppi to ensure good adsorption and evaporation efficiency. The threaded bottom cap 471 adopts a threaded detachable design. After a period of use, the user can unscrew the threaded bottom cap 471 to take out the diffuser sponge 46 for cleaning or replacement, to prevent bacteria from growing on the sponge or essential oil from deteriorating and clogging the pores after long-term use.

[0063] Regarding the setting of the check membrane inside the atmosphere tubing 48: The check membrane can adopt a duckbill valve or umbrella valve structure, and the material is silicone or EPDM rubber. The opening pressure is designed to be 0.5-2kPa, ensuring that a slight positive pressure in the diffuser chamber can open it, while the reverse pressure generated by exhalation is insufficient to open the check membrane.

[0064] Regarding the rotation range of the volute massage roller 35: By selecting positioning blocks 34 of different sizes or adjusting the arc length of the movable groove, the maximum rotation angle of the volute massage roller 35 can be controlled within the range of 15°-45°. If the rotation angle is too large, it may cause discomfort due to pulling on the skin at the corner of the eye. If the rotation angle is too small, it will not achieve an effective lifting effect. After testing, the preferred rotation angle is 25°-35°.

[0065] Regarding the differentiated thickness design of the press air bag 211: the wall thickness of the thickened spherical protrusion 214 and the thickened central protrusion 212 is recommended to be 1.5-2.5 times the wall thickness of the main body of the press air bag 211, and the wall thickness of the thin ring part 213 is recommended to be 0.5-0.7 times the wall thickness of the main body of the press air bag 211. This thickness ratio has been experimentally verified to achieve the expected effect of "thin ring expands preferentially and thick area is pressed in a concentrated manner".

[0066] Example 2; This embodiment has the same basic structure as Embodiment 1, the difference being the different control method for the rotation angle of the volute massage wheel 35.

[0067] In Embodiment 1, the rotation angle of the volute massage wheel 35 is mainly limited by the positioning block 34 between the curved arm 32 and the short arm 33. In this embodiment, the positioning block 34 is replaced by an adjustable limiting structure. The back or side of the short arm 33 is provided with a threaded hole, and an adjusting screw is screwed into the threaded hole. The end of the adjusting screw extends out of the surface of the short arm 33. When the curved arm 32 swings to form a predetermined angle with the short arm 33, the inner sidewall of the curved arm 32 forms abutment contact with the end of the adjusting screw. By rotating the adjusting screw to change its extension length, the maximum angle between the curved arm 32 and the short arm 33 can be adjusted, thereby controlling the maximum rotation angle of the volute massage wheel 35.

[0068] The beneficial effects of this embodiment are that users can adjust the rotation amplitude of the massage rollers according to their personal tolerance and preferences, so as to achieve personalized customization of the pressure and lifting stroke. The adjustment range of the adjusting screw is 0-8mm extension length, and the corresponding rotation angle adjustment range of the volute massage roller 35 is 15°-40°.

[0069] Example 3; This embodiment has the same basic structure as Embodiment 1, except that a delay valve or throttle valve is added to the pneumatic pipe 432.

[0070] In Embodiment 1, after the solenoid valve assembly 433 is opened, the air pressure is immediately transmitted to the compression bladder 431, and the aroma release and massage action are strictly synchronized. In this embodiment, a miniature throttle valve is installed in series on the pneumatic pipe 432 between the solenoid valve assembly 433 and the compression bladder 431. The throttle valve reduces the air passage diameter and slows down the speed at which the air pressure is transmitted from the solenoid valve assembly 433 to the compression bladder 431.

[0071] Specific parameters: The equivalent diameter of the throttle valve is 0.3-0.8mm, and the corresponding air pressure transmission delay is 1-3 seconds. That is, after the solenoid valve group 433 is opened, it takes 1-3 seconds for the compression bladder 431 to start expanding and drive the release of aromatherapy.

[0072] The beneficial effect of this embodiment is that in the initial stage of the massage program, that is, in the first 1-3 seconds, the air bag 211 begins to expand and presses the eye socket, but the aromatherapy has not yet been released, and the user first feels the massage effect. After 1-3 seconds, the aromatherapy begins to release. At this time, the massage has entered a deeper state. The introduction of the aroma creates a comfortable experience that gradually improves. At the same time, the delay effect of the throttling valve also makes the end time of aromatherapy release lag behind the end time of massage. The aroma can still be emitted for a few seconds during the exhaust phase, preventing the aroma from disappearing abruptly when the massage ends.

[0073] Example 4; This embodiment has the same basic structure as Embodiment 1, the difference being the connection method of the atmosphere hose 48.

[0074] In Example 1, the aroma diffuses naturally due to the concentration difference. In this example, one end of the atmosphere hose 48 is still connected to the aroma diffuser chamber, but the other end is configured to be connected to the exhaust port of the device housing 11 or the exhaust pipe of the air pump. A three-way diverter valve is set at the exhaust port of the micro air pump and the solenoid valve module assembly 24. One way is connected to the atmosphere for normal exhaust, and the other way is connected to the air inlet of the aroma diffuser chamber through the atmosphere hose 48. An air inlet is added to the side wall of the aroma cylinder 41 here.

[0075] Working process: When the air bag 211 is pressed to release the gas, part of the gas is diverted to the aroma diffuser chamber through the three-way diverter valve. The airflow blows through the aroma diffuser sponge 46 and actively blows the aroma through another air hose 48 to the nose pad outlet.

[0076] The beneficial effects of this embodiment are: the aroma is actively pushed by the airflow during the exhaust phase, and the diffusion speed and concentration of the aroma are significantly improved. At the same time, the exhaust airflow and the aroma release share the same gas source, so there is no need to add an additional air pump. In this embodiment, two air inlets 48 are provided, one for the air inlet and one for the air outlet. The inlet of the air inlet should be located at the low position of the diffuser chamber, and the outlet of the air outlet should be located at the high position of the diffuser chamber to ensure that the airflow passes evenly through the diffuser sponge 46.

[0077] The above embodiments extend the technical solution of the present invention from three dimensions: rotation angle adjustment, aroma release delay, and active aroma delivery. The embodiments can be combined with each other.

[0078] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
