Description

Technical Field

[0001] This application relates to the field of massager technology, and more particularly to a suction-type massager. Background Technology

[0002] Massagers work by vibrating the body to relieve discomfort such as muscle soreness, tension, and numbness. However, vibrating massagers cover a wide area and often cannot provide precise massage to small areas, thus failing to achieve the best massage effect. Suction massagers, on the other hand, generate suction at the suction port to stimulate and massage specific areas of the body, such as the nipples, achieving a precise massage and relaxation effect.

[0003] In existing suction-type massagers, a single suction chamber connected to the suction port is typically included. The suction force is generated at the suction port by compressing and stretching the suction chamber, thus massaging the body. However, if the single suction chamber is too small, the suction force is insufficient; if it is too large, it generates excessive noise. Therefore, existing suction-type massagers cannot balance strong suction force and low noise, resulting in a poor user experience.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0011] A suction component is fixed at the first opening of the main body. The first end of the suction component forms a suction port corresponding to the first opening. The suction component has a suction cavity communicating with the suction port and a pressure cavity communicating with the suction cavity. The second end of the suction component is connected to the driving mechanism to perform reciprocating motion under the drive of the driving mechanism, thereby generating a suction force at the suction port through the pressure cavity and the suction cavity.

[0012] Optionally, the suction member has an annular protrusion along its circumferential direction to separate the suction cavity and the pressure cavity, so that the pressure cavity, the suction cavity and the suction port are connected in sequence. When the second end of the suction member reciprocates under the drive of the driving mechanism, the pressure cavity deforms to generate positive or negative pressure, thereby forming a suction force at the suction port through the suction cavity.

[0013] Optionally, the radial dimension of the pressure chamber is larger than the radial dimension of the suction chamber.

[0024] A drive rod, one end of which is fixed to the connecting rod, and the other end of which is engaged with the second holding structure to drive the second end of the suction member to reciprocate after the motor starts working.

[0025] Optionally, the eccentric wheel includes:

[0026] A rotating disk is sleeved and fixed on the output shaft, and the rotating disk and the output shaft are concentrically arranged;

[0027] A rotating rod is vertically fixed on the rotating disk and eccentrically positioned relative to the output shaft. One end of the pendulum is sleeved on the rotating rod via the bearing.

[0028] Optionally, the body includes:

[0029] A first housing and a second housing are fastened together to fix the drive mechanism and the control component inside the main body;

[0030] An outer shell that encloses the first shell and the second shell to form the main body.

[0031] Optionally, the first housing and the second housing are provided with corresponding clearance portions, and the clearance portions combine to form the first opening after the first housing and the second housing are fastened together;

[0032] The outer shell has a through hole corresponding to the first opening. When the outer shell covers the first shell and the second shell, the through hole engages with the first opening to fix the relative position of the outer shell to the first shell and the second shell.

The body has a hollow structure and a first opening; the drive mechanism is fixed within the body; the control component is fixed within the body and electrically connected to the drive mechanism to control its start and stop; the suction element is fixed at the first opening of the body, with a first end corresponding to the first opening to form a suction port; the suction element has a suction cavity communicating with the suction port and a pressure chamber communicating with the suction cavity; the second end of the suction element is connected to the drive mechanism to reciprocate under its drive, thereby generating suction force at the suction port through the pressure chamber and the suction cavity. This application, by providing an integrated and interconnected suction cavity and pressure chamber, utilizes the pressure generated within the pressure chamber to ensure suction force, while simultaneously reducing noise during suction by ensuring the suction cavity fits snugly against specific parts of the body, thus balancing strong suction force and low noise, providing a better user experience.

[0044] This application provides a solution. To make the purpose, technical solution, and effects of this application clearer and more explicit, the following provides a more detailed description of this application. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0045] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0046] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] Suction massagers work by creating suction at the suction port to massage specific areas of the body, such as the nipples, thereby relieving stress and relaxing the body. However, the single suction chambers in existing suction massagers often cannot balance strong suction and low noise. If the chamber size is too small, it cannot provide sufficient suction, while if the chamber size is too large, it is prone to detaching from the body during use, generating noise. If a stacked chamber design is used, multiple silicone parts need to be molded separately and then glued together to form a sealed multi-chamber structure. This undoubtedly increases manufacturing difficulty and cost, and is also prone to air leakage, which can lead to reduced suction and increased noise.

[0048] Therefore, this application discloses a suction-type massager, which combines a one-piece molded and interconnected suction chamber and pressure chamber. The pressure chamber ensures suction power, while the suction chamber conforms to specific parts of the body to reduce noise during suction, thus balancing strong suction power and low noise for a better user experience. Specifically, as... Figure 1 and Figure 2As shown, the suction massager described in this application includes a body 100, a drive mechanism 200, a control component 300, and a suction element 400. The main body 100 has a hollow structure and a first opening 101. The drive mechanism 200 is fixed inside the main body 100. The control component 300 is fixed inside the main body 100 and electrically connected to the drive mechanism 200 to control the start and stop of the drive mechanism 200. The suction member 400 is fixed at the first opening 101 of the main body 100. The first end 410 of the suction member 400 forms a suction port 430 corresponding to the first opening 101. The suction member 400 has a suction cavity 440 communicating with the suction port 430 and a pressure cavity 450 communicating with the suction cavity 440. The second end 420 of the suction member 400 is connected to the drive mechanism 200 to reciprocate under the drive of the drive mechanism 200, thereby forming a suction force at the suction port 430 through the pressure cavity 450 and the suction cavity 440. This application combines a single-piece, interconnected suction cavity 440 and a pressure cavity 450. The pressure within the pressure cavity 450 ensures suction power, while the suction cavity 440 conforms to specific body parts to reduce noise during suction, thus achieving a balance between strong suction and low noise, providing a better user experience. Optionally, multiple suction cavities 440 and multiple pressure cavities 450 can be provided within the suction component 400 to match specific needs and provide corresponding suction power.

[0049] In one implementation, such as Figure 1 and Figure 5 As shown, the suction member 400 has an annular protrusion 460 along its circumferential direction to separate the suction cavity 440 and the pressure cavity 450, so that the pressure cavity 450, the suction cavity 440, and the suction opening 430 are sequentially connected. When the second end 420 of the suction member 400 reciprocates under the drive of the drive mechanism 200, the pressure cavity 450 deforms to generate positive or negative pressure, thereby forming a suction force at the suction opening 430 through the suction cavity 440. Figure 5 and Figure 8As shown, the annular protrusion 460 separates the suction chamber 440 and the pressure chamber 450, thus ensuring communication between them and guaranteeing that pressure changes caused by deformation of the pressure chamber 450 can affect the suction chamber 440. Simultaneously, it prevents deformation of the pressure chamber 450 from affecting the fit between the suction chamber 440 and the human body, reducing noise caused by separation from the body while maintaining strong suction power, providing a better user experience. Furthermore, the annular protrusion 460 effectively prevents dust, sweat, and other substances from entering the pressure chamber 450, reducing cleaning difficulty and facilitating user operation. Optionally, several annular protrusions of different shapes can be provided within the suction component 400 to create more pressure chambers and provide greater suction power.

[0050] In one implementation, such as Figure 5 As shown, the radial dimension of the pressure chamber 450 is larger than that of the suction chamber 440. Therefore, the internal space of the pressure chamber 450 is larger than that of the suction chamber 440. When the internal pressure of the pressure chamber 450 changes due to deformation, a greater suction force can be generated at the suction port 430 through the suction chamber 440. Meanwhile, the deformation of the suction chamber 440 is smaller, so it will not easily detach from the human body, thereby improving the comfort during use and avoiding noise caused by the separation of the suction massager from the human body.

[0051] In one implementation, such as Figure 5 As shown, the sidewall thickness of the pressure chamber 450 is less than the sidewall thickness of the suction chamber 440. By making the sidewall of the pressure chamber 450 thinner, it becomes easier for the pressure chamber 450 to deform, and the range of deformation is larger, thus generating greater positive or negative pressure depending on compression or stretching. By setting the sidewall thickness of the suction chamber 440 to be greater than that of the pressure chamber 450, the suction chamber 440 is prevented from detaching from specific parts of the body when the pressure chamber 450 deforms, improving user comfort and reducing noise during use.

[0052] In one implementation, such as Figure 4 and Figure 5As shown, the suction member 400 further includes a first retaining structure 470 and a second retaining structure 489. The first retaining structure 470 is disposed around the suction member 400 corresponding to the first opening 101, thereby retaining and fixing the suction member 400 at the first opening 101. The second retaining structure 489 is disposed on the second end 420 of the suction member 400, thereby retaining it with the driving mechanism 200, allowing the second end 420 of the suction member 400 to reciprocate under the drive of the driving mechanism 200. The first retaining structure 470 ensures the fixed retention of the suction member 400 with the first opening 101, thus preventing displacement of the suction member 400 relative to the body 100 when the second end 420 of the suction member 400 reciprocates with the driving mechanism 200. This enhances stability during use, effectively prevents the suction massager from separating from the human body, improves user comfort, and reduces noise during use.

[0053] In one implementation, such as Figure 3 and Figure 6 As shown, the drive mechanism 200 includes a motor 210, an eccentric wheel 220, and a pendulum 230. The motor 210 is fixed inside the body 100; the eccentric wheel 220 is sleeved and fixed on the output shaft 211 of the motor 210, rotating under the drive of the motor 210; one end of the pendulum 230 is sleeved on the eccentric wheel 220 via a bearing 240, and the other end of the pendulum 230 is clamped and connected to the second clamping structure 480, converting the rotational motion output by the motor 210 into linear reciprocating motion. With the eccentric wheel 220, when the motor 210 outputs rotational motion through the output shaft 211, the pendulum 230 follows with linear reciprocating motion, thus forming a linkage mechanism similar to a crank-slider. Furthermore, the large stroke of the pendulum 230 can drive the second end 420 to move, creating a larger positive or negative pressure at the pressure chamber 450, thereby ensuring the suction force of the suction-type massager.

[0054] In one implementation, such as Figure 6As shown, the motor 210 has two opposing output shafts 211, each with an eccentric wheel 220 mounted on it. The pendulum 230 includes a connecting rod 231 and a drive rod 232. The connecting rod 231 is U-shaped, and its two ends are respectively mounted on the eccentric wheel 220 via bearings 240. One end of the drive rod 232 is fixed to the connecting rod 231, and the other end of the drive rod 232 is engaged with the second holding structure 480 to drive the second end 420 of the suction member 400 to reciprocate after the motor 210 starts working. By incorporating U-shaped connecting rods 231 within the pendulum 230, which connect to two output shafts 211 respectively, the drive rod 232 can be positioned at the center of the motor 210 and connected to the second end 420 of the suction member 400. This reduces the size of the suction massager, resulting in a more compact overall structure that is convenient for one-handed use or portability. Furthermore, the symmetrically arranged output shafts 211 output rotational motion, ensuring greater stability of the pendulum 230's linear reciprocating motion. This guarantees uniform force distribution on the second end 420 of the suction member 400 during movement, preventing abrupt pressure changes in the pressure chamber 450 and further reducing noise during use.

[0055] In one implementation, such as Figure 3 As shown, the eccentric wheel 220 includes a rotating disk 221 and a rotating rod 222. The rotating disk 221 is sleeved and fixed on the output shaft 211, and the rotating disk 221 is concentrically arranged with the output shaft 211. The rotating rod 222 is vertically fixed on the rotating disk 221 and eccentrically arranged relative to the output shaft 211. One end of the pendulum 230 is sleeved on the rotating rod 222 via a bearing 240. The eccentric wheel 220 is formed by the rotating disk 221 and the rotating rod 222, reducing the difficulty of production and assembly, and effectively reducing product costs.

[0056] In one implementation, such as Figure 2 and Figure 7As shown, the main body 100 includes a first housing 110, a second housing 120, and an outer shell 130. The first housing 110 and the second housing 120 are fastened together to fix the drive mechanism 200 and the control component 300 inside the main body 100. The outer shell 130 encloses the first housing 110 and the second housing 120 to form the main body 100. The fastening and fixing of the drive mechanism 200 and the control component 300 by the first housing 110 and the second housing 120 reduces assembly difficulty. Furthermore, the outer shell 130 enclosing the first housing 110 and the second housing 120 enhances the stability of the suction-type massager. Additionally, the feel of the suction-type massager can be adjusted using the outer shell 130, enhancing the user experience. Optionally, the first housing 110 and the second housing 120 are symmetrical hemispherical structures, fastened together to form the spherical structure of the main body 100. Optionally, the outer shell 130 is a spherical shell, and a surface texture corresponding to a soccer ball is formed on the surface of the outer shell 130 to enhance the aesthetics of the suction massager. Optionally, the first shell 110 and the second shell 120 are made of plastic to form a rigid structure, thereby fixing the drive mechanism 200 and the control component 300; the outer shell 130 is made of silicone to form a flexible structure on the surface of the suction massager, thereby enhancing the feel of the suction massager and increasing surface friction to prevent the suction massager from falling out of the user's hand during use.

[0057] In one implementation, such as Figure 3 and Figure 7As shown, the first housing 110 and the second housing 120 are respectively provided with clearance portions 104. After the first housing 110 and the second housing 120 are fastened together, the clearance portions 104 combine to form the first opening 101. The outer shell 130 is provided with a through hole 131 corresponding to the first opening 101. When the outer shell 130 wraps around the first housing 110 and the second housing 120, the through hole 131 engages with the first opening 101, fixing the relative position of the outer shell 130 with the first housing 110 and the second housing 120. By pre-setting symmetrical clearance portions 104 on the first housing 110 and the second housing 120, the first opening 101 is naturally formed after assembly, reducing the assembly difficulty. By providing the through hole 131 on the outer shell 130, the suction member 400 can be exposed through the first opening 101 and the through hole 131, ensuring the use of the suction massager. At the same time, the fixed clamping of the through hole 131 and the first opening 101 ensures that the outer shell 130 will not shift relative to the first shell 110 and the second shell 120 during use, ensuring the stability of the product and improving the user experience of the suction massager.

[0058] In one implementation, such as Figure 3 As shown, the control component 300 includes a mainboard 310, a control button 320, and a charging dock 330. The mainboard 310 is fixed inside the body 100 and electrically connected to the drive mechanism 200 to supply power to the motor 210 in the drive mechanism 200 and control the start and stop of the motor 210. The control button 320 is electrically connected to the mainboard 310 and protrudes from the body 100 through a second opening 102, allowing the user to control the start and stop of the suction-type massager. The charging dock 330 is electrically connected to the mainboard 310 and protrudes from the body 100 through a third opening 103, allowing it to be connected to an external power source to supply power to the mainboard 310. Optionally, the outer shell 130 forms a marking area corresponding to the control button 320 to cover the control button 320, so as to mark the position of the control button 320 and prevent the control button 320 from extending directly from the body 100 to avoid scratches; the outer shell 130 forms a clearance through hole corresponding to the charging base 330 to facilitate the electrical connection of the charging base 330 with an external power source.

[0059] This application uses a one-piece molding method to manufacture the suction component, thereby obtaining a one-piece molded and interconnected suction cavity and pressure cavity. The pressure generated within the pressure cavity ensures suction power, while the suction cavity conforms to specific parts of the human body to reduce noise during suction, thus balancing strong suction power and low noise for a better user experience. Specifically, the manufacturing method of the suction component includes using an upper mold and a lower mold, wherein a cavity is formed between the upper and lower molds, and an inner core component for molding the dual-cavity suction device is disposed within the cavity. The inner core component includes a straight core and a curved core, which cooperate to form a dual-cavity structure. During injection molding, molten silicone material is injected into the cavity through the injection port, and under the action of the inner core component, a suction component with interconnected suction cavities and pressure cavities is formed in one step. Specifically, the inner core component is first installed on the lower mold, and then the upper and lower molds are closed to form the cavity, with a sealing element at the bottom of the cavity to prevent leakage of molten material. Next, molten silicone material is injected into the mold cavity through the injection port, and the suction cup is formed in one step under the action of the inner core. After molding, the upper and lower molds are opened, and the molded part is demolded from the inner core using a push plate and an air blowing device. This one-step molding process eliminates the need to mold two silicone parts separately and then glue them together, thus reducing production steps and improving production efficiency. It also avoids air leakage problems that are prone to occur in the bonding process, ensuring the airtightness of the suction cup, generating sufficient suction force, and reducing noise during use. Furthermore, this method does not require increasing the number of molds or the types of materials, nor does it require additional glue application, thereby reducing production costs. In addition, by changing the inner core of different specifications, suction cups of different sizes can be produced, increasing production flexibility.

[0060] In one embodiment, after manufacturing a one-piece suction component with interconnected pressure and suction chambers using the above method, a suction massager is assembled using the suction component, thereby achieving a technical effect that balances strong suction power and low noise, providing users with a better user experience. Specifically, as shown... Figure 8 As shown, in this embodiment, the suction component 400 is fixed to the main body 100. When the user holds the main body 100 and places the suction port 430 of the suction component 400 on the body where massage and relaxation are needed, the suction massager can be turned on. The suction force generated by the suction port 430 can achieve the effect of massaging and relaxing specific parts of the body.

[0061] Specifically, such as Figure 1 and Figure 7As shown, the main body 100 has a spherical structure, including a symmetrically arranged first shell 110 and second shell 120, and an outer shell 130 that surrounds the first shell 110 and the second shell 120. The first shell 110 and the second shell 120 are symmetrical hemispherical structures and are hollow inside. When the first shell 110 and the second shell 120 are fastened together, they form an internal receiving space to secure other components within the suction-type massager. Furthermore, the first shell 110 and the second shell 120 are made of plastic to form a rigid structure when fastened together, while the outer shell 130 is made of silicone to provide a flexible feel to the main body 100 after surrounding the first shell 110 and the second shell 120. In this embodiment, the surface of the outer shell has a texture corresponding to the surface structure of a soccer ball to enhance aesthetics and increase surface friction, making it easier for the user to hold.

[0062] Furthermore, such as Figure 7 As shown, the first housing 110 and the second housing 120 are provided with semi-circular clearance portions 104. When the first housing 110 and the second housing 120 are fastened together, the two clearance portions 104 are joined together to form a circular first opening 101 on the main body 100. Further, the first housing 110 is provided with a circular second opening 102; and the first housing 110 and the second housing 120 are also provided with square clearance structures to form a third opening 103 after the first housing 110 and the second housing 120 are joined together. In this embodiment, the outer shell 130 is provided with a through hole 131 corresponding to the first opening 101, and a matching retaining structure is provided between the through hole 131 and the first opening 101, so that after the outer shell 130 encloses the first shell 110 and the second shell 120, the outer shell 130 is retained with the first shell 110 and the second shell 120, ensuring that there is no relative displacement between the outer shell 130 and the first shell 110 and the second shell 120 during use, and ensuring that the first opening 101 matches and corresponds with the through hole 131. Further, the outer shell 130 is provided with a marking area corresponding to the second opening 102 to indicate the position of the second opening 102; the outer shell 130 is provided with a clearance through hole corresponding to the third opening 103 to ensure that the third opening 103 communicates with the outside.

[0063] Furthermore, such as Figure 2 and Figure 6As shown, a drive mechanism 200 is fixedly installed inside the main body 100. In this embodiment, a retaining plate is formed inside the first housing 110 and the second housing 120 corresponding to the drive mechanism 200, so that the drive mechanism 200 is fixed inside the main body 100 after the first housing 110 and the second housing 120 are fastened together. Specifically, the drive mechanism 200 includes a motor 210, an eccentric wheel 220, a pendulum 230, and a bearing 240, wherein the eccentric wheel 220 is sleeved on the output shaft 211 of the motor 210, and the end of the pendulum 230 is sleeved on the eccentric wheel 220 through the bearing 240. Specifically, the motor 210 includes two output shafts 211 extending in opposite directions, and the output shafts 211 are coaxially arranged to output rotational motion synchronously. Furthermore, the top end of the output shaft 211 is formed with a D-shaped cross section to cooperate with the inner flat opening of the eccentric wheel 220 to form an anti-slip fit, ensuring that the eccentric wheel 220 rotates synchronously with the output shaft 211.

[0064] Furthermore, such as Figure 3 As shown, the eccentric wheel 220 includes a rotating disk 221 and a rotating rod 222. The rotating disk 221 is sleeved on the output shaft 211 through an inner hole, and the rotating disk 221 is coaxially arranged with the output shaft 211 to rotate synchronously with the output shaft 211. The rotating rod 222 is vertically fixed on the rotating disk 221, parallel to the output shaft 211, and eccentrically arranged with the output shaft 211. When the output shaft 211 rotates, the rotating rod 222 rotates around the axis of the output shaft 211. The pendulum 230 includes a U-shaped connecting rod 231 and a drive rod 232 arranged on the axis of symmetry of the connecting rod 231 to cooperate with the eccentric wheel 220 to convert the rotational motion of the output shaft 211 into linear reciprocating motion. Specifically, the U-shaped ends of the connecting rod 231 are respectively positioned corresponding to the two output shafts 211 of the motor 210, and are respectively sleeved on the output shafts 211 by two sets of bearings 240 and eccentric wheels 220, thereby ensuring that the rotational motion transmitted from the two output shafts 211 is synchronously transmitted to the connecting rod 231, so that the drive rod 232 outputs linear reciprocating motion uniformly. Further, the drive rod 232 is provided with a locking protrusion to engage with the second end 420 of the suction member 400, driving the second end 420 to move and periodically generating positive and negative pressure within the suction member 400.

[0065] Furthermore, such as Figure 1 As shown, the suction-type massager also includes a control component 300, which is fixed inside the main body 100. Specifically, as... Figure 2 and Figure 3As shown, the control component 300 includes a motherboard 310, a control button 320, and a charging dock 330. In this embodiment, the first housing 110 and the second housing 120 are provided with several slots to respectively hold the motherboard 310 and the charging dock 330, fixing the control component 300 inside the body 100. Specifically, the motherboard 310 is electrically connected to the motor 210 in the drive mechanism 200 to provide power to the motor 210 and control the start and stop of the motor 210. One end of the control button 320 is fixed to the motherboard 310 and electrically connected to the motherboard 310 to control the start and stop of the motor 210 through the motherboard 310; the other end of the control button 320 extends through the second opening 102 on the body 100 for user operation. Furthermore, the marked area on the outer casing 130 covers the control button 320 to prevent the control button 320 from being exposed from the main body 100 and scratching the user, thus ensuring a uniform design on the surface of the suction massager. Furthermore, the charging base 330 is electrically connected to the main board 310 and extends from inside the main body 100 through the third opening 103 and the clearance through-hole on the outer casing 130 to communicate with the outside, thereby connecting to an external power source to power the main board 310 and the motor 210.

[0066] Furthermore, such as Figure 1 As shown, the suction member 400 is fixed at the first opening 101. In this embodiment, the suction member 400 has a bell-like structure, including a cylindrical first end 410 and a cylindrical second end 420 with a smaller diameter. A first retaining structure 470 is provided around the first end 410 corresponding to the first opening 101, and the suction member 400 is retained and fixed at the first opening 101 by the first retaining structure 470. Further, a second retaining structure 480 is formed in the second end 420, and the second retaining structure is provided corresponding to the top retaining structure of the drive rod 232, so as to realize the retaining connection between the second end 420 and the drive rod 232, so that the second end 420 can follow the drive rod 232 to perform linear reciprocating motion.

[0067] Furthermore, such as Figure 5As shown, the suction component 400 has an integrally formed, interconnected pressure chamber 450 and suction chamber 440, with the suction chamber 440 communicating with the outside through a suction port 430. In this embodiment, the radial dimension of the pressure chamber 450 is larger than that of the suction chamber 440, and the sidewall thickness of the pressure chamber 450 is smaller than that of the suction chamber 440. This ensures that when the pressure chamber 450 deforms under the action of the second end 420 to generate positive or negative pressure, the shape of the suction chamber 440 remains unchanged or changes only slightly. This ensures that the suction chamber 440 can always adhere to the area to be massaged on the human body, avoiding detachment and noise. By setting an integrally formed and interconnected suction chamber 440 and pressure chamber 450, this application utilizes the pressure formed within the pressure chamber 450 to ensure suction power, while simultaneously utilizing the close contact between the suction chamber 440 and a specific part of the human body to reduce noise during the suction process. This achieves a balance between strong suction power and low noise, providing users with a better user experience.

[0068] In another implementation, such as Figure 9 As shown, the suction member 400 includes a suction chamber 440, a first pressure chamber 4501 and a second pressure chamber 4502 connected in series, which are separated by an annular protrusion 460 and a separating protrusion 4601, respectively, to further improve the suction force at the suction port 430 while reducing noise.

[0069] In yet another implementation, such as Figure 10 As shown, the suction device includes a suction cavity 440 and two pressure chambers respectively communicating with the suction cavity 440. An annular protrusion 460 separates the pressure chambers and the suction cavity 440 to ensure that the positive / negative pressure generated at the pressure chamber can generate suction force at the suction opening 430 through the suction cavity 440. Furthermore, a separating protrusion 4601 extending axially along the suction device 400 divides the pressure chamber into a first pressure chamber 4501 and a second pressure chamber 4502 to ensure the suction force generated at the suction opening 430.

[0070] The following is a brief explanation of the working process of the suction massager described in this application:

[0071] After holding the suction massager, the user places the suction port 430 on a specific area requiring massage and relaxation (e.g., the nipple), aligns the suction cavity 440 within the suction member 400 with the area to be massaged, and then activates the drive mechanism 200 via the control button 320 on the control component 300. Once the motor 210 in the drive mechanism 200 starts working, the eccentric wheel 220 and pendulum 230 within the drive mechanism 200 work together to convert the rotational motion of the output shaft 211 of the motor 210 into linear reciprocating motion, and the pendulum 230 drives the second end 420 of the suction member 400 to synchronously perform linear reciprocating motion. At this time, the pressure chamber 450 within the suction device 400 undergoes periodic expansion and contraction as the second end 420 moves, thereby periodically generating positive and negative pressure within the pressure chamber 450. Through the suction chamber 440, which communicates with the pressure chamber 450, and the suction opening 430, which communicates with the suction chamber 440, suction force is generated at the suction opening 430, achieving a massage and relaxation effect on specific parts of the body. Since the suction chamber 440 and the pressure chamber 450 are integrally formed and interconnected, the pressure generated within the pressure chamber 450 ensures suction force, while the close contact between the suction chamber 440 and specific parts of the body reduces noise during suction, thus balancing strong suction force and low noise, providing a better user experience.

[0072] In summary, this application discloses a suction-type massager, comprising: a body, a drive mechanism, a control component, and a suction element. The body has a hollow structure and a first opening; the drive mechanism is fixed within the body; the control component is fixed within the body and electrically connected to the drive mechanism to control its start and stop; the suction element is fixed at the first opening of the body, with a first end corresponding to the first opening to form a suction port; the suction element has a suction cavity communicating with the suction port and a pressure chamber communicating with the suction cavity; the second end of the suction element is connected to the drive mechanism to reciprocate under its drive, thereby generating suction force at the suction port through the pressure chamber and the suction cavity. This application, by providing an integrated and interconnected suction cavity and pressure chamber, utilizes the pressure generated within the pressure chamber to ensure suction force, while simultaneously reducing noise during suction by ensuring the suction cavity fits snugly against specific parts of the body, thus balancing strong suction force and low noise, providing a better user experience.
