Abstract
Description
Technical Field
[0001] This application relates to the field of massage equipment, and in particular to a massage mechanism. Background Technology
[0002] Existing massage devices typically include an elastic diaphragm made of a soft and flexible material, such as silicone. One side of the diaphragm is connected to the drive mechanism, while the other side comes into direct or indirect contact with the body. When the drive mechanism operates, it causes the diaphragm to reciprocate. As the diaphragm moves in one direction, the space within it increases, causing the internal gas to be compressed; conversely, as the diaphragm moves in the opposite direction, the space within it decreases, causing the internal gas to expand. This compression and expansion of the gas creates a pump-like effect, stimulating the skin and muscle tissue. The diaphragm is relatively fragile and susceptible to wear and tear. Especially with prolonged use or exposure to significant external force, it may break, thus affecting the lifespan of the massager.
[0003] Therefore, it is necessary to improve existing massagers to avoid the aforementioned defects. Summary of the Invention

[0015] In one embodiment, when there are two pipe walls, the opening is formed between the two pipe walls, and the two pipe walls extend toward the opening and are provided with clamping portions.

[0016] In one embodiment, the two clamping portions are provided with two grooves opposite each other, and the connecting end is sleeved on the rotating shaft to form a protrusion. The two grooves rotate to seal and clamp the protrusion.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.
[0036] The present application will now be described in detail with reference to the accompanying drawings.
[0037] To solve the above technical problems, combined with Figures 1-3As shown, this application provides a massage mechanism comprising a housing 1 with at least one suction port 131 connected to a cavity 14 inside the housing 1. The suction port 131 directly or indirectly contacts human skin. The massage mechanism also includes a drive structure 2 and a piston 3. The piston 3 is inserted into the cavity 14, and the drive structure 2 is connected to the connecting end 31 of the piston 3, driving the working end 32 of the piston 3 to reciprocate. The working end 32 of the piston 3 compresses or expands the gas in the cavity 14, and under atmospheric pressure, the suction port 131 produces a suction and release massage effect on the human skin. The massage mechanism of this application uses the drive structure 2 to drive the piston 3 to reciprocate within the cavity 14, generating negative pressure for massage. Compared to diaphragm methods, this structure is relatively simple and robust, maintaining good stability under normal use and is less prone to malfunction.
[0038] In one embodiment of this application, combined with Figure 3 and Figure 4 As shown, piston 3 is inserted into cavity 14, thereby dividing the entire cavity 14 into two independent air chambers, namely the first air chamber 141 and the second air chamber 142. When piston 3 reciprocates under the drive of drive structure 2, the gas state in the first air chamber 141 and the second air chamber 142 changes accordingly. Specifically, when piston 3 moves towards the first air chamber 141, the gas in the first air chamber 141 is compressed, causing its internal pressure to increase; at the same time, the gas in the second air chamber 142 is in an expanded state, and its internal pressure decreases accordingly, generating negative pressure. Conversely, when piston 3 moves towards the second air chamber 142, the gas in the second air chamber 142 is compressed, and its pressure increases, while the gas in the first air chamber 141 is in an expanded state, and its pressure decreases, generating negative pressure. Therefore, either or both of the first air chamber 141 and the second air chamber 142 can be provided with a suction port 131 for massage. In addition, the negative pressure generated by the swing of piston 3 reduces the friction between piston 3 and cavity 14, which can also reduce the possibility of piston 3 not sealing properly due to wear.
[0039] In one embodiment of this application, a single suction port 131 is provided, which is connected to either the first air chamber 141 or the second air chamber 142. When connected to the first air chamber 141, the pressure increases when the gas in the second air chamber 142 is compressed. This causes the gas in the first air chamber 141 to expand, generating negative pressure. By connecting the suction port 131 to the first air chamber 141, the negative pressure within the first air chamber 141 can be used to achieve skin adsorption and massage. Conversely, when connected to the second air chamber 142, the gas expands when the gas in the first air chamber 141 is compressed, generating negative pressure. Similarly, by connecting the suction port 131 to the second air chamber 142, the transmission of negative pressure and massage function can also be achieved. Providing only one suction port 131 concentrates the output of negative pressure, ensuring a more uniform and stable adsorption force on the skin during massage. This single-opening design 135 avoids the negative pressure dispersion or unevenness that may occur between multiple suction ports 131, thereby improving the precision and consistency of the massage effect. In addition, the single suction port 131 design also helps to simplify the manufacturing process, reduce costs, and facilitate user operation and cleaning.
[0040] In another embodiment of this application, combined with Figure 3 and Figure 4 As shown, two suction ports 131 are provided, each located at a different position on the housing 1 and connected to the first air chamber 141 and the second air chamber 142 respectively. The two suction ports 131 can independently utilize the negative pressure changes within the first air chamber 141 and the second air chamber 142 to achieve suction and massage of the user's skin. The first air chamber 141 is connected to one of the suction ports 131. When the piston 3 moves towards the first air chamber 141, the gas in the first air chamber 141 is compressed, while the gas in the second air chamber 142 expands, generating negative pressure. At this time, the suction port 131 connected to the second air chamber 142 suctions the skin. Conversely, when the piston 3 moves towards the second air chamber 142, the gas in the second air chamber 142 is compressed, while the gas in the first air chamber 141 expands, generating negative pressure. At this time, the suction port 131 connected to the first air chamber 141 suctions the skin. With two suction ports 131 connected to the first air chamber 141 and the second air chamber 142 respectively, the massage mechanism can achieve alternating suction and massage between the two suction ports 131 during the reciprocating motion of the piston 3. This alternating action not only increases the rhythm of the massage but also simulates an effect closer to real manual massage, such as "kneading" or "massage". Preferably, in the initial state, the piston 3 is in the middle position of the cavity 14, thereby dividing the cavity 14 into the first air chamber 141 and the second air chamber 142, so that the massage effect of the two suction ports 131 is approximately or the same.
[0041] In one embodiment of this application, combined with Figures 3-5As shown, the width of piston 3 is adapted to the thickness of cavity 14, allowing the upper and lower sides of piston 3 to contact the upper and lower inner walls of cavity shell 144 for swinging. The edge of working end 32 of piston 3 is in close contact with arc-shaped sidewall 143 for swinging, ensuring good sealing between piston 3 and cavity shell 144 during movement, thus ensuring the efficiency and stability of gas compression. When piston 3 reciprocates under the drive of drive structure 2, its working end 32 moves along the trajectory of arc-shaped sidewall 143, gradually compressing the gas in cavity 14 to pipe wall 13. Expansion also occurs from the adjacent pipe wall 13, generating negative pressure at suction port 131. This design allows for flexible adjustment of the intensity and frequency of negative pressure based on the movement speed and amplitude of piston 3. Preferably, in this application, two pipe walls 13 are provided, spaced apart on opposite sides of arc-shaped sidewall 143, and piston 3 is positioned between the two pipe walls 13, reciprocating to drive the two suction ports 131 for massage.
[0042] In one embodiment of this application, combined with Figures 2-4 , Figure 6 and Figure 7 As shown, preferably, the piston 3 is configured as a plate-like structure. This plate-like design allows the piston 3 to reciprocate within the cavity 14 with minimal resistance. Due to its flat shape, the piston 3 compresses and expands the gas more evenly during movement, thereby improving the efficiency of negative pressure generation. The plate-like piston 3 has a smaller volume, allowing it to better fit within the internal space of the cavity shell 144, making the entire massage mechanism more compact. The shape and size of the opening 135 match the connecting end 31 of the piston 3 to ensure that the connecting end 31 can smoothly pass through the opening 135 and seal it. The rotating shaft 33 extends along the thickness direction of the shell 1. The connecting end 31 of the piston 3 is fitted onto the rotating shaft 33, so that when the drive structure 2 drives the connecting end 31 to swing, the working end 32 swings up and down around the rotating shaft 33. Preferably, the rotating shaft 33 is positioned along the opening 135, so the size of the opening 135 does not change with the swing of the piston, facilitating sealing. Optionally, the rotating shaft 33 can also be located near the opening 135, and the opening 135 and the plug can also be sealed by a soft membrane connection to provide space for the plug to swing.
[0043] In one embodiment of this application, combined with Figures 2-5As shown, when the tube walls 13 are spaced two apart, the opening 135 is located between the two tube walls 13. Each of the two tube walls 13 extends towards the opening 135 and is provided with a clamping part 132. The inner walls 133 of the two clamping parts 132, the inlets of the two tube walls 13, and the arc-shaped sidewalls 143 together form the inner wall of the cavity shell 144. The inner walls 133 of the two clamping parts 132 cooperate to form a V-shaped limiting surface. The V-shaped limiting surface matches the movement trajectory of the piston 3, which can limit the swing angle of the piston 3, thus limiting the movement range of the piston 3 to a preset angle range, thereby avoiding mechanical failures or unstable massage effects caused by excessive swinging of the piston 3.
[0044] In one embodiment of this application, combined with Figures 3-6 As shown, preferably, the rotating shaft 33 is disposed in the opening 135, and the connecting end 31 is sleeved on the rotating shaft 33 near the working end 32. It is understood that the connecting end 31 is made of a flexible material, such as silicone. When the connecting end 31 is sleeved on the rotating shaft 33, it conforms to the shape of the rotating shaft 33, forming two opposing protrusions 34. Preferably, the protrusions 34 are arc-shaped protrusions. Two clamping portions 132 are provided with two opposing grooves 134, the shape and size of which perfectly match the two arc-shaped protrusions. Furthermore, the two grooves 134 clamp the arc-shaped protrusions, meaning each groove 134 is sealed and fitted to each arc-shaped protrusion, and the arc-shaped protrusions can rotate relative to the grooves 134. This sealing between the grooves 134 and the arc-shaped protrusions reduces the possibility of gas leakage and improves the operating efficiency of the massage mechanism.
[0045] In one embodiment of this application, combined with Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the drive structure 2 includes a drive motor 21, an eccentric wheel 22, a mounting component 23, and a connecting rod structure 24. The working end of the drive motor 21 is connected to the eccentric wheel 22 to convert the rotational motion of the drive motor 21 into the eccentric rotational motion of the eccentric wheel 22. The mounting component 23 is mounted on the housing 1, and multiple connecting rods 16 extend outward from both sides of the housing 1. The multiple connecting rods 16 are fixedly connected to the mounting component 23 by screws or other locking components. Preferably, the mounting component 23 is located on the side adjacent to the connecting end 31 of the piston 3, and the mounting component 23 is used to support the connecting rod structure 24. The connecting rod structure 24 is movably mounted on the mounting component 23 and includes a first end 25 and a second end 26. The first end 25 of the connecting rod structure 24 is connected to the eccentric wheel 22, and the second end 26 is connected to the connecting end 31 of the piston 3. During rotation, the eccentric wheel 22 can generate a periodic eccentric force, thereby converting the rotational motion of the motor into linear reciprocating motion. When the eccentric wheel 22 rotates, its eccentric force is transmitted through the first end 25 of the connecting rod structure 24, causing the connecting rod structure 24 to move up and down. This up-and-down movement is transmitted through the second end 26 of the connecting rod structure 24 to the connecting end 31 of the piston 3, thereby realizing the reciprocating oscillation of the piston 3. The connecting rod structure 24 can efficiently transmit power during movement and reduce energy loss. In this application, the housing 1 also includes a receiving cavity 15, in which the drive motor 21 is disposed for installation and shock absorption. The housing 1 is formed by assembling an upper shell 11 and a lower shell 12, which are symmetrically arranged. Thus, by opening the upper shell 11 or the lower shell 12, the cavity 14 and the receiving cavity 15 can be opened, facilitating the assembly, maintenance, and replacement of the piston 3 and the drive motor 21.
[0046] In one embodiment of this application, combined with Figure 5 and Figure 6As shown, the connecting rod structure 24 includes a base 241, which is connected to an eccentric wheel 22. The eccentric wheel 22 drives the connecting rod structure 24 to move up and down through the base 241. Connecting beams 242 are mounted on the base 241. Preferably, two connecting beams 242 are provided, and they transmit the movement of the base 241 to the connecting end 31 of the piston 3. Each connecting beam 242 extends with a sleeve 2421, which slides with the column 231 on the mounting member 23, thereby enabling the connecting rod structure 24 to move up and down. The connecting end 31 of the piston 3 extends through the rotating shaft 33 with a connecting portion 311, which is connected to the connecting beam 242. The connecting portion 311 transmits the movement of the connecting rod structure 24 to the piston 3, thereby enabling the reciprocating motion of the piston 3. A notch is formed between the two connecting beams 242, and a notch is also provided on the mounting member 23, allowing one of the tube walls 13 to penetrate the notch, thus preventing the connecting rod structure 24 from affecting the operation of the suction port 131. In addition, preferably, the connecting part 311 can be configured as a U-shaped structure with a U-shaped groove, thus forming two ends. Each end is provided with a column 312, and each connecting beam 242 is provided with a slot 2422, which can be rotated to engage the columns 312 to drive the piston 3 to swing. During the swinging of the piston 3, one of the tube walls 13 can pass through the U-shaped groove, which can prevent the connecting end 31 from being too wide and affecting the operation of the suction port 131.
[0047] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this application specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
