Description

Technical Field

[0001] This utility model relates to a massager. Background Technology

[0002] With the continuous improvement of people's living standards and the continuous development of science and technology, more and more massage products are entering people's lives. However, most existing massager products rely on mechanical contact vibration or suction massage to achieve their massage function, which makes it difficult to provide a better user experience. For example, continuous vibration of mechanical contact massage can cause neurotransmitter depletion, leading to decreased sensitivity, and also carries the risk of mechanical damage. Similarly, closed suction massage, due to negative pressure suction, can lead to the risk of soft tissue strain. Utility Model Content

[0003] This invention provides an improved massager. The massager includes a chamber, an outlet connecting the chamber to the outside, and an airflow generator. The airflow generator is adapted to generate a vibrating airflow within the chamber and directs the vibrating airflow through the outlet to the massage area. This invention achieves a massage effect by using vibrating airflow to act on the massage area, allowing the massager to move freely within the massage area. It overcomes the risks of soft tissue strain caused by negative pressure suction in closed-loop suction massage, and the risks of neurotransmitter depletion, decreased sensitivity, and mechanical damage caused by continuous vibration in mechanical contact vibration massage.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A massager includes: a chamber; an outlet connecting the chamber to the outside; and an airflow generator adapted to generate a vibrating airflow within the chamber and to cause the vibrating airflow to exit through the outlet and act on a massage area.

[0006] In some embodiments, the chamber is a non-sealed chamber.

[0007] In some embodiments, the chamber has a through-hole communicating with the outside and / or the outlet has a corrugated edge to allow air circulation between the inside and outside of the chamber.

[0008] In some embodiments, the chamber includes a first chamber, a second chamber, and a chamber passage connecting the first chamber and the second chamber; the first chamber is adapted to at least partially accommodate the airflow generator to generate the vibrating airflow within the first chamber; the second chamber has the outlet; and the chamber passage is adapted to guide the vibrating airflow from the first chamber to the outlet of the second chamber.

[0009] In some embodiments, the first chamber and the second chamber are rigid chambers; the chamber passage is formed through a trachea.

[0010] In some embodiments, the trachea is adapted to bend and / or twist; the massager further includes a housing adapted to receive the chamber; the housing is provided with a metal strip at the trachea; the housing and the metal strip are also adapted to bend and / or twist at the trachea.

[0011] In some embodiments, the airflow generator includes a piston; the piston is at least partially located within the chamber and is adapted to reciprocate to generate the vibrating airflow within the chamber.

[0012] In some embodiments, the massager further includes a drive unit; the drive unit includes a motor, a crank, and a connecting rod connected in sequence; the connecting rod is connected to the piston; the motor is adapted to rotate at a constant speed to drive the piston to generate a sinusoidal airflow in the chamber in sequence through the crank and the connecting rod.

[0013] In some embodiments, the massager further includes a flexible sealing ring and a rigid sealing ring arranged radially between the piston and the inner wall of the chamber to achieve static sealing and dynamic sealing, respectively.

[0014] In some embodiments, the piston has an annular groove disposed around its circumference; at least a portion of the flexible sealing ring and the rigid sealing ring are disposed within the annular groove.

[0015] Compared with the prior art, the technical solution of this utility model has at least the following beneficial effects.

[0016] For example, this invention uses vibrating airflow to act on the massage area to achieve the massage effect, which allows the massager to move freely in the massage area. It overcomes the risks of soft tissue strain caused by negative pressure adsorption in closed suction massage, as well as the risks of neurotransmitter depletion, decreased sensitivity, and mechanical damage caused by continuous vibration in mechanical contact vibration massage.

[0017] For example, this invention uses the reciprocating motion of a piston to compress air and form a stable, periodic sinusoidal airflow. The vibration is transmitted through the collision of air molecules in the airflow and acts on the massage area to achieve a massage effect. During the massage, the sinusoidal airflow can stably transition between large and small flow rates, thereby avoiding the stinging sensation caused by the instantaneous changes of non-sinusoidal waves such as square waves.

[0018] For example, by making the chamber of the massager non-sealed, this invention can avoid the risk of soft tissue strain caused by negative pressure adsorption due to a closed chamber.

[0019] For example, this invention sets the chamber of the massager as a rigid chamber, which can generate a continuous and stable airflow, thereby avoiding the airflow of a flexible chamber being easily affected by the outlet.

[0020] For example, this invention sets the massager's chambers as a first chamber, a second chamber, and a chamber passage, which allows for flexible adjustment of the internal space and keeps the airflow generator away from the outlet to avoid contamination.

[0021] For example, this invention can change the position and angle of the massager outlet by bending and / or twisting the corresponding parts of the trachea and the outer shell, thereby making it suitable for people of different physiques and different massage areas.

[0022] For example, by setting the inner diameter of the trachea to be smaller than the inner diameter of the first inner shell and the second inner shell, the trachea can be made thinner relative to the first inner shell and the second inner shell, so as to facilitate bending and / or twisting.

[0023] For example, the second outer shell of this utility model is made of flexible material and has bendable metal strips on both sides, which can facilitate bending and / or twisting of the trachea. Attached Figure Description

[0038] To make the objectives, features, and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described below are merely for explaining this utility model and are not intended to limit it. Furthermore, descriptions of identical or similar components in different embodiments, as well as descriptions of components, features, effects, etc., belonging to the prior art, may be omitted.

[0039] Furthermore, for ease of description, only the parts relevant to this invention are shown in the accompanying drawings, not the entire structure. Also, the same or similar reference numerals may be used in the drawings to refer to the same or similar components in different embodiments.

[0040] Reference Figures 1 to 5 This utility model embodiment provides a massager 1.

[0041] Specifically, the massager 1 includes a housing 10, a chamber 30 at least partially formed within the housing 10, an outlet 34 connecting the chamber 30 and the outside of the massager 1, and an airflow generator 40. The airflow generator 40 is adapted to generate a vibrating airflow within the chamber 30 and to exit the chamber 30 through the outlet 34, thereby acting on the massage area.

[0042] In this embodiment of the invention, the outlet 34 of the massager 1 can either directly act on the massage area (i.e., directly contact the massage area) or not directly act on the massage area (i.e., not directly contact the massage area). When the outlet 34 of the massager 1 does not directly act on the massage area, the outlet 34 can be positioned close to the massage area so that the vibrating airflow from the outlet 34 can act on the massage area.

[0043] In practice, chamber 30 is not sealed. This avoids negative pressure adsorption caused by a sealed chamber.

[0044] In some embodiments, the chamber 30 has a through hole 35 communicating with the outside of the massager 1. In this way, even if the outlet 34 directly acts on the massage area, the chamber 30 can form a non-sealed space, thereby allowing air to circulate inside and outside the chamber 30, so as to avoid negative pressure adsorption caused by the chamber being closed.

[0045] In some embodiments, the outlet 34 also has a corrugated edge 341. Thus, even if the outlet 34 acts directly on the massage area, a gap can be formed between the outlet 34 and the massage area to make the chamber 30 a non-sealed space, thereby allowing air to circulate inside and outside the chamber 30 to avoid negative pressure adsorption caused by the chamber being closed.

[0046] In some embodiments, the chamber 30 includes a first chamber 31, a second chamber 32, and a chamber passage 33 connecting the first chamber 31 and the second chamber 32. The first chamber 31 is adapted to at least partially accommodate the airflow generator 40 to generate a vibrating airflow within the first chamber 31; the second chamber 32 has an outlet 34; and the chamber passage 33 is adapted to guide the vibrating airflow from the first chamber 31 to the outlet 34 of the second chamber 32.

[0047] In this embodiment of the invention, the chamber 30 is configured as a first chamber 31, a second chamber 32, and a chamber channel 33, which allows for flexible adjustment of the internal space of the chamber 30.

[0048] In some embodiments, the massager 1 further includes an inner shell at least partially disposed within the outer shell 10, and the inner shell includes a first inner shell 21, a second inner shell 22, and an air tube 23 connecting the first inner shell 21 and the second inner shell 22. The first inner shell 21 is adapted to define a first chamber 31, the second inner shell 22 is adapted to define a second chamber 32, and the air tube 23 is adapted to define a chamber passage 33.

[0049] In some embodiments, the chamber 30 is at least partially a rigid chamber. This facilitates the generation of a continuous and stable vibrating airflow within the chamber 30, thereby avoiding the airflow in a flexible chamber being easily affected by the outlet 34.

[0050] In some embodiments, the first inner shell 21, the second inner shell 22, and the air tube 23 are all made of rigid materials, so that the chamber 30 formed by the first chamber 31, the second chamber 32, and the chamber passage 33 is a rigid chamber as a whole. This facilitates the generation of a continuous and stable vibrating airflow within the chamber 30, thereby avoiding the airflow in the flexible chamber being easily affected by the outlet 34.

[0051] In some embodiments, the first inner shell 21 and the second inner shell 22 are both made of rigid materials, while the trachea 23 is made of a flexible material. This ensures that at least the first chamber 31 and the second chamber 32 are rigid chambers. This also facilitates the generation of a continuous and stable vibrating airflow within the chamber 30, thereby preventing the airflow in the flexible chamber from being easily affected by the outlet 34.

[0052] In some embodiments, the trachea 23 is adapted to bend and / or twist. Accordingly, the housing 10 is also adapted to bend and / or twist at the chamber passage 33. Thus, by bending and / or twisting the corresponding portions of the trachea 23 and the housing 10, the position and angle of the outlet 34 can be changed, thereby adapting to people of different physiques and different massage areas.

[0053] In some embodiments, the inner diameter of the trachea 23 is smaller than the inner diameter of the first inner shell 21 and the second inner shell 22. This allows the trachea 23 to be relatively thinner than the first inner shell 21 and the second inner shell 22, facilitating bending and / or twisting.

[0054] In some embodiments, the outer casing 10 may further include a first outer casing 11 and a second outer casing 12 connected in sequence. The first outer casing 11 is adapted to house the first inner casing 21, and the second outer casing 12 is adapted to house the air tube 23.

[0055] In some embodiments, the second outer shell 12 may be made of a flexible material or a bendable material, and its inner walls are respectively provided with metal strips 70 suitable for bending and deformation.

[0056] In practice, the metal strip 70 is adapted to bend and / or twist so as to drive the trachea 23 to bend and / or twist, thereby changing the position and angle of the outlet 34 to suit people of different physiques and different massage areas.

[0057] In some embodiments, one end of the second outer shell 12 is connected to the first outer shell 11, and the other end is connected to the second inner shell 22. One end of the second inner shell 22 extends into the second outer shell 12 and is connected to the air tube 23, and the other end forms an outlet 34.

[0058] In some embodiments, the massager 1 further includes a cover 60 disposed outside the housing 10.

[0059] In a specific implementation, the cover 60 is adapted to cover the first outer shell 11, the second outer shell 12 and the second inner shell 22, and defines the boundary of the outlet 34 at the other end of the second inner shell 22.

[0060] In some embodiments, the housing 60 may be made of a flexible material. This not only improves the user's grip on the massager 1, but also enhances contact comfort when the outlet 34 directly applies pressure to the massage area.

[0061] In some embodiments, the airflow generator 40 includes a piston 41. The piston 41 is at least partially located within the chamber 30 and is adapted to reciprocate to generate a vibrating airflow within the chamber 30.

[0062] In a specific implementation, the piston 41 is at least partially disposed in the first chamber 31 and is adapted to reciprocate within the first chamber 31 to generate a vibrating airflow within the first chamber 31, thereby causing the vibrating airflow to exit the outlet 34 sequentially through the chamber channel 33 and the second chamber 32, thus acting on the massage area at or outside the outlet 34.

[0063] In some embodiments, the massager 1 further includes a flexible sealing ring 42 and a rigid sealing ring 43 arranged radially between the piston 41 and the inner wall of the first chamber 31 to achieve static sealing and dynamic sealing, respectively.

[0064] In some embodiments, the flexible sealing ring 42 may be made of a sealing material with good elasticity, such as nitrile rubber, hydrogenated nitrile rubber, or fluororubber.

[0065] In some embodiments, the rigid sealing ring 43 may be made of materials with low friction and good wear resistance, such as polytetrafluoroethylene (PTFE), nylon, and polyoxymethylene (POM).

[0066] Furthermore, the rigid sealing ring 43 can also serve as a guide during the movement of the piston 41.

[0067] In some embodiments, the piston 41 further has an annular groove 411 disposed circumferentially therearound it. At least a portion of the flexible sealing ring 42 and the rigid sealing ring 43 may be accommodated within the annular groove 411 to constrain the axial position of the flexible sealing ring 42 and the rigid sealing ring 43 relative to the piston 41, thereby preventing the flexible sealing ring 42 and the rigid sealing ring 43 from disengaging from the piston 41.

[0068] In some embodiments, grease may be added between the piston 41 and the inner wall of the first chamber 31 to reduce friction.

[0069] In some embodiments, the massager 1 further includes a drive unit 50 for driving the piston 41 to reciprocate.

[0070] In some embodiments, the drive unit 50 includes a motor 51, a crank 52, and a connecting rod 53 connected in sequence. The connecting rod 53 is connected to the piston 41.

[0071] In some embodiments, the motor 51 is adapted to rotate at a constant speed to drive the piston 41 in the first chamber 31 to generate a sinusoidal airflow, i.e., a vibrating airflow whose flow velocity changes periodically with time according to a sinusoidal function, via the crank 52 and connecting rod 53 in sequence.

[0072] In this embodiment of the invention, the reciprocating motion of the piston 41 compresses the air to form a stable, periodic sinusoidal airflow. The vibration is transmitted through the collision of air molecules in the airflow and acts on the massage area to achieve a massage effect.

[0073] Within one motion cycle, the speed of piston 41 is not constant. When piston 41 is at either end of its stroke (i.e., the start / end point), motor 51 rotates to the "dead point," at which point the speed of piston 41 is 0. When piston 41 moves to the middle position of its stroke, its speed reaches its maximum value (approximately the peak of a sine curve). Thus, during the propulsion phase, when piston 41 extrudes gas forward, the airflow intensity changes with the speed of piston 41, increasing from 0, reaching a peak at the middle position, and then decreasing back to 0. When it decreases to 0, it corresponds to piston 41 reaching the end of its stroke. During this process, the airflow generated by piston 41 steadily transitions from a small flow rate to a large flow rate, thereby avoiding the stinging sensation on the massage area caused by the instantaneous changes in stimulation of a non-sinusoidal wave, such as a square wave.

[0074] In practice, the frequency of the sinusoidal airflow can be adjusted as needed according to the rotational speed of the motor 51.
