[0005] Optionally, the pushrod assembly includes: a pushrod; a pushrod seal fixedly connected to the pushrod, wherein the pushrod seal is located between the pushrod and the air inlet end.

[0006] Optionally, the tube body includes a tube body end and a tube body main body. The tube body end is located near the first air nozzle, and the inner diameter of the tube body end is smaller than the inner diameter of the tube body main body. The top rod seal includes a first sealing part. The first sealing part is a variable diameter structure. The minimum outer diameter of the first sealing part is larger than the inner diameter of the tube body end, and the maximum outer diameter of the first sealing part is smaller than the inner diameter of the tube body main body.

[0007] Optionally, the maximum outer diameter of the first sealing part matches the inner diameter of the pipe body, and a portion of the first sealing part abuts against the inner surface of the pipe body.

[0008] Optionally, the push rod seal further includes a second sealing part connected to the first sealing part, and the second sealing part is closer to the first air nozzle relative to the first sealing part; the outer diameter of the second sealing part is smaller than the inner diameter of the tube end, and the axial length of the second sealing part is smaller than the axial length of the tube end; wherein, when the first air nozzle is in the first position, the second sealing part is inside the tube end; when the first air nozzle is in the second position, at least a portion of the second sealing part disengages from the tube end and enters the tube body.

[0009] Optionally, the axial length of the second sealing part matches the axial length of the pipe end, and when the first air nozzle is in the first position, the second sealing part abuts against the end of the pipe end that is away from the main body of the pipe; and / or, the outer diameter of the second sealing part matches the inner diameter of the pipe end, and when the first air nozzle is in the first position, the second sealing part abuts against the inner surface of the pipe end.

[0010] Optionally, the second nozzle further includes: a reset member disposed within the tube body and located below the push rod assembly, for applying an upward force to the push rod assembly; the reset member and the inner wall of the tube body have a space for gas to pass through.

[0011] Optionally, the second air nozzle includes a first portion extending along a first direction and a second portion extending along a second direction; the first portion is disposed close to the first air nozzle, the second portion communicates with the first portion, and the push rod assembly and the reset member are disposed along the first direction.

When the push rod assembly is in the first position, it blocks the tube, obstructing the air flow path between the air pump and the air bag, preventing the air pump from inflating the air bag. When the push rod assembly is controlled to be pressed down to the second position, a gap forms between the tube and the push rod assembly, connecting the air flow path between the air pump and the air bag, allowing the air pump to inflate the air bag.

[0015] Corresponding to different inflation levels of the airbag, the size of the space between the airbag and the massage plate varies. The pressure applied by the airbag to the user's feet within this space also varies, resulting in different massage intensities. Therefore, by changing the position of the first air nozzle and the operating state of the air pump, the inflation state of the airbag can be controlled, thereby controlling the massage intensity. This improves the controllability of the massage intensity, enhances the massage effect, and optimizes the user experience. Attached Figure Description

Detailed Implementation

[0018] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.

[0019] Combination Figures 1 to 11 This application provides a foot massager, including a housing 10, a massage disc 20, an air bag 30, a first air nozzle 40, a second air nozzle 50, and an air pump 60.

[0020] The massage plate 20 is disposed within the housing 10. Two ends of the air bag 30 are fixedly disposed on the massage plate 20, forming a receiving space between the air bag 30 and one side of the massage plate 20. The first air nozzle 40 includes an air inlet 403 and an air outlet, the air outlet being connected to the air bag 30. The second air nozzle 50 includes a tube 51 and a push rod assembly 52 movably disposed within the tube 51. The tube 51 communicates with the air inlet 403, and the push rod assembly 52 is located below the air inlet 403. An air pump 60 is connected to the tube 51 and is used to deliver gas into the tube 51. The first air nozzle 40 can be pressed downwards to move the push rod assembly 52 downwards. The push rod assembly 52 includes a first position and a second position located below the first position. When the push rod assembly 52 is in the first position, it blocks the tube 51, preventing the air pump 60 from communicating with the air inlet 403. When the push rod assembly 52 is in the second position, a gap is formed between the push rod assembly 52 and the tube body 51 to allow gas to pass through, so that the air pump 60 is connected to the air inlet end 403.

[0021] The foot massager provided in this embodiment forms an accommodating space between the air bag 30 fixed on the massage plate 20 and one side of the massage plate 20, allowing the user's foot to extend into this space. The tubes 51 of the air bag 30, the first air nozzle 40, and the second air nozzle 50, together with the air pump 60, form a gas flow path. A push rod assembly 52, movably disposed inside the tube 51, is located below the first air nozzle 40. When the first air nozzle 40 moves downward, it pushes the push rod assembly 52 downward, changing its position. When the push rod assembly 52 is in the first position, it blocks the tube 51, obstructing the air flow path between the air pump 60 and the air bag 30, preventing the air pump 60 from inflating the air bag 30. When the push rod assembly 52 is controlled to be pressed down to the second position, a gap forms between the tube 51 and the push rod assembly 52, connecting the air flow path between the air pump 60 and the air bag 30, allowing the air pump 60 to inflate the air bag 30.

[0022] Corresponding to different inflation levels of the air bag 30, the size of the space between the air bag 30 and the massage plate 20 varies. The pressure applied by the air bag 30 to the user's feet within this space results in different massage intensities. Thus, by changing the position of the first air nozzle 40 and the operating state of the air pump 60, the inflation state of the air bag 30 can be controlled, thereby controlling the massage intensity. This improves the controllability of the massage intensity, enhances the massage effect, and optimizes the user experience.

[0023] The foot massager housing 10 has an internal receiving cavity 100, within which a massage disc 20 is disposed. One side of the massage disc 20 forms a first receiving cavity, and the other side forms a second receiving cavity. An air bag 30 is located within the first receiving cavity. When using the foot massager, the user places their foot within the first receiving cavity, in the gap between the air bag 30 and the massage disc 20.

[0024] Specifically, the massage disc 20 includes a massage disc housing and a massage component 21 mounted on the massage disc housing. The massage disc housing supports the user, and the massage component 21 massages the user's feet while they are positioned on the massage disc housing. More specifically, the massage component 21 massages the sole area of ​​the user's feet. In some embodiments, a portion of the massage component 21 is disposed in a second receiving cavity, and another portion extends toward the side where the first receiving cavity is located to contact the user's feet. More specifically, in some embodiments, the massage disc housing has a through hole through which a portion of the massage component 21 can extend toward the side where the first receiving cavity is located.

[0025] Combination Figure 2As shown, the air bag 30 includes at least two fixed ends disposed at both ends. The air bag 30 is fixedly connected to the massage plate 20 via these fixed ends. The portion of the air bag 30 not fixed to the connecting plate, located between the fixed ends, forms a space with the side of the massage plate 20 near the first receiving cavity, capable of accommodating the user's foot. During use, part of the user's foot passes through this space. For example, the air bag 30 has two fixed ends, respectively disposed at both ends, fixing both ends of the air bag 30 to the massage plate 20. The middle region of the air bag 30 protrudes relative to the massage plate 20, forming a space with the side of the massage plate 20 near the first receiving cavity, capable of accommodating the user's foot. Thus, when the air bag 30 is inflated, the space between the air bag 30 and the massage plate 20 decreases, applying pressure to the user's foot, increasing the force between the user's foot and the massage component 21, and increasing the massage intensity. Conversely, when the air bag 30 is not inflated or is only lightly inflated, the space between the air bag 30 and the massage plate 20 is larger, resulting in less pressure on the user's feet and a weaker massage intensity. Thus, the massage intensity can be controlled by adjusting the inflation of the air bag 30.

[0026] In at least some embodiments, the first air nozzle 40 is fixedly connected to the massage plate 20. After the massage plate 20 is correctly installed inside the foot massager, it can move downwards to drive the first air nozzle 40, which in turn drives the top rod assembly 52 to move, thus connecting the gas flow path between the air pump 60 and the air bag 30, allowing the air pump 60 to inflate the air bag 30. In some embodiments, the first air nozzle 40 is located below the massage plate 20 and abuts against it. Thus, after the massage plate 20 is correctly installed inside the foot massager, it can move downwards to drive the first air nozzle 40, which in turn drives the top rod assembly 52 to move, thus connecting the gas flow path between the air pump 60 and the air bag 30, allowing the air pump 60 to inflate the air bag 30.

[0027] The aforementioned second air nozzle 50 is fixedly connected to the housing 10. For example, it is fixed to the bottom of the housing 10 by screws, or to the bottom of the barrel.

[0028] In some embodiments, the air bag 30 includes a first air bag 31 and a second air bag 32. One of the first air bag 31 and the second air bag 32 corresponds to the left foot position, and the other corresponds to the right foot position. The first air bag 31 and the second air bag 32 work together to control the pressure applied to the user's left and right feet, that is, to control the massage intensity of both feet. The two ends of the first air bag 31 and the two ends of the second air bag 32 are respectively fixedly connected to the massage plate 20 to fix the first air bag 31 and the second air bag 32.

[0029] When the air bag 30 includes a first air bag 31 and a second air bag 32, the air outlet includes a first air outlet and a second air outlet. The aforementioned first air nozzle 40 is, for example, a three-way nozzle, including a first air outlet, a second air outlet, and an air inlet. The foot massager also includes a first air inlet pipe 310 and a second air inlet pipe 320. The first air inlet pipe 310 connects the first air bag 31 and the first air outlet. The second air inlet pipe 320 connects the second air bag 32 and the second air outlet. By setting the first air bag 31 and the second air bag 32 to correspond to the left and right feet respectively, and in conjunction with the first and second air outlets and the first and second air inlet pipes 310 and 320, the massage intensity for the user's feet can be controlled.

[0030] like Figure 3 As shown, in some embodiments, a connecting region 312 is provided between the first air bag 31 and the second air bag 32, and the connecting region 312 connects the first air bag 31 and the second air bag 32, serving a connecting function. In at least some embodiments, the connecting region 312 does not allow gas to pass through, and the first air bag 31 and the second air bag 32 are each an independent space.

[0031] like Figures 6 to 11 As shown, in some embodiments, the push rod assembly 52 includes a push rod 521 and a push rod seal 522 fixedly connected, with the push rod seal 522 located between the push rod 521 and the air inlet end of the first air nozzle 40. The push rod seal 522 is positioned near the end of the massage plate 20 relative to the push rod 521. Designing the push rod assembly 52 such that the push rod 521 and the push rod seal 522 are fixedly connected, with the push rod seal 522 near the end of the massage plate 20, ensures good sealing performance of the push rod assembly 52 during movement. When the push rod assembly 52 is in different positions, the push rod seal 522 can tightly cooperate with components such as the tube body 51, effectively preventing gas leakage and ensuring the normal opening and closing of the air passage. This ensures that the inflation and deflation process of the air bag 30 is carried out accurately and without error, thereby stably controlling the massage intensity and improving the reliability and stability of the massage effect of the entire massager.

[0032] In some embodiments, the foot massager further includes a reset member 53, which is disposed within the tube body 51 and located below the push rod assembly 52. ​​The reset member 53 applies an upward force to the push rod assembly 52. ​​A space for gas to pass through is provided between the reset member 53 and the inner wall of the tube body 51. By providing the reset member 53 in the second air nozzle 50 and applying an upward force to the push rod assembly 52, the push rod assembly 52 can automatically return to its initial position, i.e., the first position, when no external force is applied, thus sealing the tube body 51 and cutting off the connection between the air pump 60 and the air inlet. This ensures the airtightness of the air path when not triggered and also improves the stability and reliability of the push rod assembly 52's movement. Simultaneously, the space for gas to pass through is maintained between the reset member 53 and the inner wall of the tube body 51, ensuring smooth movement of the push rod assembly 52 within the tube while avoiding interference with normal gas flow. This helps ensure the accuracy and stability of massage intensity control, improves the massage effect of the foot massager, and ultimately optimizes the user experience. Specifically, the reset member 53 contacts the end of the push rod 521 away from the first air nozzle 40, and is used to apply an upward force to the push rod 521, thereby applying an upward force to the push rod seal 522.

[0033] In some embodiments, the end of the reset member 53 furthest from the push rod assembly 52 is fixedly connected to the tube body 51. That is, the end of the reset member 53 furthest from the push rod seal 522 is fixedly connected to the tube body 51. This helps to prevent the reset member 53 from shifting or loosening during operation, thereby ensuring that the reset member 53 reliably provides an upward force to the push rod assembly 52, and thus ensuring that the push rod assembly 52 accurately returns to its initial position, which helps to ensure the accuracy of the motion control of the push rod assembly 52.

[0034] like Figure 11 As shown, in some embodiments, the push rod 521 includes a push rod end and a push rod body. At least a portion of the push rod end is covered by a push rod seal. The push rod body is located on the side away from the push rod seal 522 relative to the push rod end. The bottom surface area of ​​the top end is larger than the area of ​​the push rod body. The reset member 53 surrounds the push rod body and abuts against the push rod end. This helps prevent slippage between the reset member 53 and the push rod 521, ensuring the reliability of the push rod assembly 52's operation. For example, if the reset member 53 is a spring, the spring is arranged around the push rod 521 body and abuts against the lower surface of the push rod 521 end, thus limiting the spring's position.

[0035] In some embodiments, the aforementioned reset member 53 includes an elastic reset member. This provides a stable and reliable reset force for the push rod assembly 52. ​​The elastic reset member is, for example, a spring. When the push rod assembly 52 is subjected to an external force and moves downward, the elastic reset member is compressed, storing elastic potential energy. When the external force disappears, the elastic reset member quickly releases the elastic potential energy, pushing the push rod assembly 52 to quickly return to its initial position, sealing the tube 51 and cutting off the air passage. The responsiveness of the push rod assembly 52 ensures the timeliness and accuracy of air passage opening and closing, and also enhances the stability and reliability of the system. Simultaneously, the elastic characteristics of the elastic reset member make the reset process smoother, which helps reduce mechanical shock and extend the service life of each component. During real-time operation, the reset force of the elastic reset member can be adjusted and selected according to actual needs, thereby adapting to different usage scenarios and user requirements. In other embodiments, the reset member 53 may also be a pneumatic reset member 53, an electric reset member 53, a mechanical reset member 53, etc.

[0036] like Figure 7 As shown, in some embodiments, the second air nozzle 50 includes a first portion extending along a first direction and a second portion extending along a second direction; the first portion is disposed near the first air nozzle 40, and the second portion communicates with the first portion; the top rod seal 522 and the top rod 521 are disposed along the first direction. Further, in some embodiments, when the second air nozzle 50 includes a reset member 53, the top rod seal 522, the top rod 521, and the reset member 53 are disposed along the first direction. This first direction is different from the second direction. Designing the second air nozzle 50 to include a first portion and a second portion extending in different directions, and with the top rod seal 522 and the top rod 521 disposed along the first direction, avoids excessive length in a single direction and adapts to the internal spatial layout of the foot massager. Simultaneously, it helps reduce gas resistance during transmission, improves gas transmission efficiency, thereby making the inflation and deflation process of the air bag 30 faster and smoother, further enhancing the timeliness and accuracy of massage intensity control. In some embodiments, the second air nozzle 50 is an L-shaped air nozzle. The first direction and the second direction are perpendicular to each other. Thus, the second air nozzle 50 is more compact in space, adapting to the limited space in the foot massager.

[0037] In some embodiments, the reset member 53 is fixedly disposed at the intersection of the first part and the second part, that is, corresponding to the bottom of the first part in the first direction. In this way, space can be fully utilized.

[0038] In some embodiments, the tube body 51 includes a tube end 511 and a tube body 512. The tube end 511 is located near the first air nozzle 40, and the inner diameter of the tube end 511 is smaller than the inner diameter of the tube body 512. The push rod seal 522 includes a first sealing portion 5221. The first seal 83 has a variable diameter structure, where the minimum outer diameter of the first sealing portion 5221 is larger than the inner diameter of the tube end 511, and the maximum outer diameter of the first sealing portion 5221 is smaller than the inner diameter of the tube body 512. The tube end 511 and the tube body 512, in conjunction with the variable diameter structure of the first sealing portion 5221 of the push rod seal 522, enable the push rod assembly 52 to effectively seal or open the tube body 51 at different positions. Specifically, as shown... Figure 8 As shown, when the push rod assembly 52 is in the first position, the first sealing part 5221 abuts against the tube end 511, preventing gas flow. Figure 9 As shown, when the push rod assembly 52 is in the second position, the first sealing part 5221 is disengaged from the tube end 511, forming a gap between it and the tube 51, allowing gas to pass through. Figure 9 The shaded area in the image is used to show relative to... Figure 8 The movement stroke of the center rod assembly 52 when it is in the first position. In this way, the tight fit between the first sealing part 5221 and the inner surface of the tube body 512 ensures the stability of the air bag 30 inflation process, thereby improving the accuracy of the massage intensity control of the foot massager.

[0039] In some embodiments, the maximum outer diameter of the first sealing portion 5221 matches the inner diameter of the tube body 512, and a portion of the first sealing portion 5221 abuts against the inner surface of the tube body 512. The matching of the maximum outer diameter of the first sealing portion 5221 with the inner diameter of the tube body 512 ensures tight contact between the two, thereby preventing gas leakage and improving the sealing performance of the push rod assembly 52. ​​Simultaneously, it helps ensure the stability of the push rod assembly 52's movement, thereby improving the reliability of inflation control.

[0040] In some embodiments, the first sealing portion 5221 has an inwardly recessed portion. The diameter of the recessed portion region in the second sealing portion 5222 is the minimum outer diameter of the first sealing portion 5221, while the non-recessed portion is the maximum outer diameter. In some embodiments, the first sealing portion 5221 has multiple recesses. Further, in some embodiments, the multiple recesses are evenly distributed circumferentially. This helps to ensure the uniformity of gas flow and also evenly distributes the pressure on the first sealing portion 5221, avoiding excessive local pressure on the first sealing portion 5221, which helps to reduce the risk of damage to the first sealing portion 5221 and improve the service life of the first sealing portion 5221.

[0041] Combination Figure 10 , 11In some embodiments, the push rod seal 522 further includes a second sealing portion 5222 connected to the first sealing portion 5221, and the second sealing portion 5222 is closer to the first air nozzle 40 relative to the first sealing portion 5221. The outer diameter of the second sealing portion 5222 is smaller than the inner diameter of the tube end 511, and the axial length of the second sealing portion 5222 is smaller than the axial length of the tube end 511. When the first air nozzle 40 is in the first position, the second sealing portion 5222 is inside the tube end 511; when the first air nozzle 40 is in the second position, at least a portion of the second sealing portion 5222 disengages from the tube end 511 and enters the tube body 512. The push rod seal 522 is provided with a second sealing portion 5222, and the design of its outer diameter and axial length allows the second sealing portion 5222 to produce different mating states with the tube end 511 when the first air nozzle 40 is in different positions. When the first air nozzle 40 is in the first position, the second sealing part 5222 is located inside the tube end 511, serving as an auxiliary seal and further optimizing the sealing effect. When the first air nozzle 40 is in the second position, at least a portion of the second sealing part 5222 protrudes from the tube end 511 and enters the tube body 512, which helps ensure smooth gas flow. This not only enhances the sealing performance but also optimizes the control of gas flow, making the inflation and deflation process of the air bag 30 more stable and reliable, thereby improving the accuracy of massage intensity control and ultimately optimizing the user's massage experience.

[0042] In some embodiments, the first sealing part 5221 and the second sealing part 5222 are integrally formed. They are a single unit. This avoids gaps between the first sealing part 5221 and the second sealing part 5222, thereby ensuring the sealing performance of the push rod seal 522.

[0043] In some embodiments, the axial length of the second sealing portion 5222 matches the axial length of the tube end 511. When the first air nozzle 40 is in the first position, the second sealing portion 5222 abuts against the end of the tube end 511 that is away from the tube body 512. The matching of the axial length of the second sealing portion 5222 with the axial length of the tube end 511 ensures that when the first air nozzle 40 is in the first position, the second sealing portion 5222 can tightly abut against the end of the tube end 511 that is away from the tube body 512. This further enhances the sealing effect of the push rod seal 522, ensuring that gas does not leak from the tube end 511 when the air passage is closed, thus improving the accuracy of gas control in the air bag 30. Simultaneously, it helps ensure the movement stability of the push rod assembly 52, thereby improving the stability of the air bag 30 during inflation.

[0044] In some embodiments, the outer diameter of the second sealing portion 5222 matches the inner diameter of the tube end. When the first air nozzle 40 is in the first position, the second sealing portion 5222 abuts against the inner surface of the tube end. The matching of the outer diameter of the second sealing portion 5222 with the inner diameter of the tube end ensures that when the first air nozzle 40 is in the first position, the second sealing portion 5222 can tightly abut against the inner surface of the tube end. This enhances the sealing performance of the push rod seal 522, ensuring that gas does not leak from the end of the pipe when the air path is closed, thus improving the reliability of air path control. Simultaneously, it helps ensure the movement stability of the push rod assembly 52, thereby improving the stability of the air bag 30 during inflation.

[0045] The housing 10 includes an outer shell and an inner shell 101 disposed within the outer shell. During use of the foot massager, the receiving cavity 100 inside the inner shell 101 is used to receive the user's feet and contains water. The receiving cavity 100 inside the inner shell 101 is not connected to the interlayer space between the outer shell and the inner shell 101 to prevent water in the receiving cavity 100 of the inner shell 101 from entering the interlayer space. The massage plate 20, the air bag 30, and the first air nozzle 40 are all disposed within the receiving cavity 100 of the inner shell 101. Part of the second air nozzle 50 is disposed within the receiving cavity 100 of the inner shell 101, and part is disposed within the interlayer space.

[0046] In some embodiments, the foot massager includes one or more air nozzle sealing rings. The air nozzle sealing rings isolate the interior of the second air nozzle from the receiving cavity, preventing water from the receiving cavity from entering the second air nozzle during use. The air nozzle sealing ring 81 is disposed around the connection between the first air nozzle 40 and the second air nozzle 50. Specifically, the air nozzle sealing ring is fixedly disposed within the inner shell. More specifically, the foot massager includes an air nozzle cap 82 disposed around the air nozzle sealing ring 81, and the air nozzle cap 82 is fixedly connected to the inner shell 101 to secure the air nozzle sealing ring 81. In some embodiments, the air nozzle cap 82 is fixedly connected to the inner shell 101 by screws. In some embodiments, the second air nozzle 50 is provided with a sealing ring 83 to isolate the interior of the second air nozzle 50 from the receiving cavity 100, achieving a waterproof seal.

[0047] In some embodiments, combined with Figure 4 , Figure 5As shown, the foot massager also includes an air valve 70, which is connected between the second air nozzle 50 and the air pump 60. The air valve 70, connected between the second air nozzle 50 and the air pump 60, allows for further control of the airflow. By opening and closing the air valve 70, the gas flow between the air pump 60 and the air bag 30 can be more precisely controlled, thereby accurately adjusting the inflation and deflation process of the air bag 30. This not only improves the accuracy of massage intensity control but also enhances its reliability, further improving the massage experience. It is understood that the foot massager includes connecting pipes between the components. Specifically, the connecting pipes connect the second air nozzle 50 and the air pump 60. More specifically, the first connecting pipe 71 connects the second air nozzle 50 and the air valve 70, and the second connecting pipe 72 connects the air valve 70 and the air pump 60. The inflation process can be controlled by opening and closing the air valve 70. Furthermore, in at least some embodiments, the air valve 70 is also used to release air, venting the gas from the air bag 30. This helps to further improve the accurate control of the inflation state of the air bag 30.

[0048] In some embodiments, the power of the air pump 60 can be controlled and adjusted. The inflation / deflation force of the air bag 30 can be adjusted by controlling the power of the air pump 60. For example, a three-level air pressure adjustment button can be used.

[0049] In some embodiments, the foot massager includes a control panel electrically connected to the air pump 60. Thus, the air pump 60 can be controlled via the control panel. In some embodiments, the control panel includes a pressure adjustment button to control the inflation level. For example, a three-pressure adjustment button may be provided.
