[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When using, the user manually holds the handle, places the massage ball side of the massage head in contact with the skin, and presses the handle towards the side closest to the skin, so that the massage ball is in close contact with the skin. Under the pressing action, the entire mounting shell moves into the mounting groove and compresses the first spring, causing the first spring to generate elastic force. When the rolling cylinders on both sides of the mounting shell come into contact with the user's skin, the massage head can be moved to perform a massage. Through the elastic squeezing force of the first spring on the mounting shell, the user's skin is massaged, which helps the user to control the massage intensity of the massage head, avoiding excessive massage intensity that may cause injury to the body, and also avoiding insufficient massage intensity that may affect the massage effect.

[0021] 2. By setting a receiving cavity inside the massage head, massage liquid is added into the receiving cavity through a medium adding mechanism. The massage liquid is then transported into the rolling drum through a medium delivery mechanism and flows out from the connecting hole on the rolling drum. During the massage, the rolling drum rolls on the user's skin, thus spreading the massage liquid onto the user's body, which helps to enhance the massage effect. Alternatively, the medium adding mechanism can be connected to an external fumigation device to add fumigation vapor into the receiving cavity. The fumigation vapor is then transported into the rolling drum through a medium delivery mechanism and flows out from the connecting hole on the rolling drum. During the massage, the user simultaneously receives fumigation, which helps to enhance the massage effect. Attached Figure Description

[0035] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0036] like Figures 1 to 12 The handheld automatic adaptive medium heating massager shown includes a massage head 1 and a handle 2. The handle 2 is fixed to one side of the massage head 1. A heating plate 3 is fixed at the bottom edge of the massage head 1. A mounting groove 4 is opened at the center of the bottom surface of the massage head 1. A mounting shell 5 is slidably connected inside the mounting groove 4. A first spring 6 is fixed between the inner wall of the mounting shell 5 and the mounting groove 4. A motor 7 is fixed inside the mounting shell 5. The output shaft of the motor 7 passes through the mounting shell 5 and extends out and is fixed to a massage disc 8. Multiple massage balls 9 are rotatably connected to the bottom surface of the massage disc 8.

[0037] Both sides of the massage head 1 are provided with rolling cylinders 10, and both ends of the rolling cylinders 10 are rotatably connected to rotating columns 11. A positioning plate 12 is fixed at the end of the rotating column 11 away from the rolling cylinders 10, and the top of the positioning plate 12 is fixed on the bottom surface of the massage head 1.

[0038] The massage head 1 has two receiving cavities 13 inside, and the two receiving cavities 13 are connected by a connecting groove 14. The inner wall of the receiving cavity 13 is provided with a medium adding mechanism for adding massage auxiliary medium into the receiving cavity 13.

[0039] A medium conveying mechanism is provided between the receiving cavity 13 and the rolling cylinder 10. The medium conveying mechanism is used to convey the massage medium into the rolling cylinder 10. Two rows of connecting holes 15 are opened on the surface of the rolling cylinder 10. In operation, existing handheld massagers are mostly used by pressing the massage head of the massager onto the user's body by hand. It is difficult to accurately control the pressure of the massage head 1 by hand. If too much force is applied, it may cause injury to the user's body. If too little force is applied, it may affect the massage effect. This embodiment of the present invention can solve the above problems. The specific working method is as follows: In use, the user manually holds the handle and presses the massage head 1. One side of the massage ball 9 on the massage head 1 contacts the skin, and the handle 2 is pressed towards the side closest to the skin, so that the massage ball 9 is in close contact with the skin. Under the pressing action, the mounting shell 5 moves into the mounting groove 4 as a whole and compresses the first spring 6, so that the first spring 6 generates elastic force. When the rolling cylinders 10 on both sides of the mounting shell 5 come into contact with the user's skin, the massage head 1 can be moved to perform massage. Through the elastic squeezing force provided by the first spring 6 on the mounting shell 5, the user's skin is massaged, which helps the user to control the massage intensity of the massage head 1, avoiding excessive massage intensity that may cause damage to the body, and also avoiding insufficient massage intensity that may affect the massage effect.

[0040] Furthermore, by setting a receiving cavity 13 inside the massage head 1, massage liquid is added into the receiving cavity 13 through a medium adding mechanism, and the massage liquid is transported into the rolling cylinder 10 through a medium conveying mechanism and flows out from the connecting hole 15 on the rolling cylinder 10. During the massage, the rolling cylinder 10 rolls on the user's skin, thereby applying the massage liquid to the user's body, which helps to promote the massage effect.

[0041] Alternatively, the medium adding mechanism can be connected to an external fumigation device to add fumigation vapor into the receiving cavity 13. The vapor is then transported into the rolling cylinder 10 via the medium conveying mechanism and flows out from the connecting hole 15 on the rolling cylinder 10. During the massage, the user can simultaneously undergo fumigation, which helps to enhance the massage effect.

[0042] As a further embodiment of the present invention, the medium addition mechanism includes a liquid inlet 16 and an air inlet 17. Both the liquid inlet 16 and the air inlet 17 are formed on the outer wall of the massage head 1, and both the liquid inlet 16 and the air inlet 17 are connected to the receiving cavity 13. A sealing plug 18 is inserted inside the liquid inlet 16, and an air inlet pipe 19 is fixed inside the air inlet 17. A one-way valve 20 for one-way air intake into the receiving cavity 13 is fixed inside the air inlet pipe 19. During operation, by setting the liquid inlet 16, the receiving cavity 13 can be filled with liquid massage agent. The sealing plug 18 can block and seal the liquid inlet 16 after the liquid is added. By setting the air inlet pipe 19, the receiving cavity 13 can be filled with fumigated medicinal vapor to complete the addition function. By setting the one-way valve 20, the liquid inlet pipe is sealed in one direction to prevent the medicine inside the receiving cavity 13 from flowing out from the air inlet pipe 19.

[0043] As a further embodiment of the present invention, the medium conveying mechanism includes a positioning cylinder 21 and a connecting groove 22. The positioning cylinder 21 is fixed between two rotating columns 11 and is eccentrically disposed inside the rolling cylinder 10. The bottom of the positioning cylinder 21 contacts the inner wall of the rolling cylinder 10. A rectangular groove 23 is formed inside the positioning cylinder 21. The rotating columns 11 and the positioning plate 12 are both hollow. The connecting groove 22 is formed on the inner bottom surface of the receiving cavity 13. The rectangular groove 23 is sequentially connected to the rotating columns 11, the positioning plate 12, and the connecting groove 22. A groove is formed at the lower end of the rectangular groove 23. Multiple liquid outlet holes 24 penetrate the outer wall of the positioning cylinder 21. During operation, after the medicine enters the receiving cavity 13, it passes through the positioning plate 12 and the rotating column 11 in sequence along the connecting groove 22, and then enters the rectangular groove 23. As the rolling cylinder 10 rotates, when the connecting hole 15 on the rolling cylinder 10 is aligned and connected with the liquid outlet hole 24, the medicine flows out from the liquid outlet hole 24 and the connecting hole 15, and then intermittently contacts the user's skin to complete the delivery function. This allows the medicine to be intermittently applied to the user's skin, which helps to improve the massage effect.

[0044] As a further embodiment of the present invention, a switching strip 25 is slidably connected inside the rectangular groove 23, and an electric push rod 26 is fixed on the inner top surface of the rectangular groove 23. The piston rod of the electric push rod 26 is fixed to the switching strip 25. A pressure control mechanism for controlling the contraction of the electric push rod 26 under liquid pressure is provided inside the receiving cavity 13. An air outlet groove 27 is opened at the upper end of the rectangular groove 23, and the air outlet groove 27 penetrates the outer wall of the positioning cylinder 21. During operation, the liquid medicine comes into intermittent contact with the patient's skin, which helps to save medicine, but the gaseous medicine vapor needs to be continuously exposed to the skin. When fumigating the user's skin, intermittent steam release can affect the auxiliary therapeutic effect. This embodiment of the invention can solve the above problem. The specific working method is as follows: In the initial state, the electric push rod 26 is in an extended state. Under the obstruction of the switching strip 25, the upper part of the rectangular groove 23 is connected to the interior of the rotating column 11. When fumigation gas is introduced into the receiving cavity 13, the gas flows from the exhaust groove 27 at the top of the rectangular groove 23 to the interior of the rolling cylinder 10. Since two rows of connecting holes 15 are opened on the side wall of the rolling cylinder 10, even if one row of connecting holes 15 is connected to the exhaust groove 27, the gas can still flow into the interior of the rotating cylinder 10. When the liquid holes 24 are connected, making it difficult for the steam to pass through, the connecting holes 15 in the other row can also connect with the air outlet 27 to discharge the steam, thus ensuring a continuous discharge of the steam and providing continuous fumigation to the user's massage area, thereby improving the massage effect. When liquid medicine is introduced into the receiving cavity 13, under the action of liquid pressure, the pressure control mechanism controls the electric push rod 26 to retract, thereby pulling the switching bar 25 upward through the electric push rod 26, so that the lower part of the rectangular groove 23 connects with the interior of the rotating column 11, and the liquid... The body energy flows towards the liquid outlet 24 at the bottom of the rectangular groove 23, so that when using the medicinal liquid, the medicinal liquid is discharged through the liquid outlet 24 at the bottom of the receiving cavity 13, and then through the connecting hole 15, so that the medicinal liquid is discharged intermittently, which helps to avoid the large amount of medicinal liquid flowing out and affecting the massage of the user. When using steam, the steam is discharged through the steam outlet groove 27 at the top of the receiving cavity 13, and then through the connecting hole 15, so that the steam is discharged continuously, which helps to maintain the fumigation effect when using steam fumigation massage.

[0045] As a further embodiment of the present invention, the pressure control mechanism includes a mounting hole 28, which is formed on the inner bottom surface of the receiving cavity 13. A trigger switch 29 is fixed inside the mounting hole 28, and a sealing plate 30 is provided above the trigger switch 29. The sealing plate 30 slides and seals with the mounting hole 28. A second spring 31 is fixed between the sealing plate 30 and the inner bottom surface of the mounting hole 28. A vent hole 32 is provided at the bottom of the mounting hole 28, and the vent hole 32 penetrates the outer wall of the massage head 1. During operation, when liquid is introduced into the receiving cavity 13, the sealing plate 30 moves downward under the pressure of the liquid and compresses the second spring 31. The gas inside 8 is discharged from the vent 32. After the sealing plate 30 is pressed down, it contacts the trigger switch 29. The trigger switch 29 can be a pressure switch. When the pressure switch is pressed, the electric push rod 26 is activated to retract, thereby adjusting the position of the switching bar 25 and moving the switching bar 25 upward. This automatically identifies the liquid medium and directs the liquid to the outlet 24. When the liquid has completely flowed out of the receiving cavity 13, the pressure switch loses the pressure of the liquid. Under the push of the second spring 31, the sealing plate 30 is disengaged from the pressure switch, thereby resetting the electric push rod 26 and moving the switching bar 25 downward, completing the switching of the gas path.

[0046] As a further embodiment of the present invention, two extrusion plates 33 are slidably connected inside each of the two receiving cavities 13. The extrusion plates 33 are symmetrically arranged on both sides of the mounting hole 28. A third spring 34 is fixed between the two extrusion plates 33 and the inner wall of the receiving cavity 13. Limiting plates 35 are fixed on opposite sides of the two extrusion plates 33. A connecting hose 36 is fixedly connected between the two extrusion plates 33 near the connecting groove 22. During operation, during massage, the bottom surface of the massage head 1 is difficult to always face downwards, thus making it difficult to maintain the pressing state of the sealing plate 30. This embodiment of the present invention can... To solve the above problems, the specific working method is as follows: by setting two extrusion plates 33, under the elastic force of the third spring 34, the two extrusion plates 33 always tend to move closer to each other. The two extrusion plates 33 extrude the liquid inside the receiving cavity 13, so that no matter what angle the massage head 1 is at, under the extrusion force, the liquid always tends to extrude the sealing plate 30, which helps to maintain the stability of the sealing plate 30. In addition, a limit plate 35 is set between the two extrusion plates 33 to limit the minimum distance between the two extrusion plates 33, so as to facilitate the passage of gas or liquid.

[0047] As a further embodiment of the present invention, an airflow guiding mechanism is provided on the top surface of the rolling cylinder 10. The airflow guiding mechanism is used to guide the airflow flowing out of the rolling cylinder 10 to the user's skin. The airflow guiding mechanism includes an arc-shaped plate 37, the two ends of which are slidably connected to the positioning plate 12. Two arc-shaped rubber strips 38 are provided between the arc-shaped plate 37 and the rolling cylinder 10. The two arc-shaped rubber strips 38 are symmetrically fixed at both ends of the outer wall of the arc-shaped plate 37 and are in contact with the outer wall of the rolling cylinder 10. During operation, because the arc-shaped plate 37 is provided above the rolling cylinder 10, when the airflow flowing out of the rolling cylinder 10 is steam, the airflow from the rolling cylinder 10 will be directed to the user's skin. During the rolling process, the connecting hole 15 on the rolling cylinder 10 moves to the side away from the skin to discharge the fumigation vapor, resulting in the loss of some fumigation vapor. This embodiment of the present invention can solve the above problem. The specific working method is as follows: when the connecting hole 15 of the rolling cylinder 10 moves to the side away from the skin to discharge the fumigation vapor, the fumigation vapor is guided by the arc plate 37, so that the fumigation vapor moves along the outer wall of the arc plate 37 to the side closer to the skin, thereby helping to reduce the loss of fumigation vapor. Furthermore, by setting the arc rubber strip 38, a gap is formed between the arc plate 37 and the rolling cylinder 10, which facilitates the passage of gas.

[0048] As a further embodiment of the present invention, a connecting plate 39 is fixed on the top surface of the arc plate 37. One end of the connecting plate 39 is in contact with the mounting shell 5. A pushing block 40 is fixed on the mounting shell 5. The pushing block 40 is located below the connecting plate 39. A fourth spring 41 is fixed between the connecting plate 39 and the bottom surface of the massage head 1. During operation, when the massager is not in use, the connecting plate 39 is pushed downward under the elastic force of the fourth spring 41, so that the arc-shaped rubber strip 38 on the arc plate 37 and the rolling cylinder 10 are in close contact, and the rolling cylinder 10 is rubbed and positioned. This helps to maintain the stability of the rolling cylinder 10 when the massager is not in use and prevents the rolling cylinder 10 from rolling and causing liquid to flow out. When the massager is used for massage, the mounting shell 5 moves upward under the manual pressing action, and drives the pushing block 40 to push the connecting plate 39 upward, thereby canceling the positioning of the rolling cylinder 10.

[0049] As a further embodiment of the present invention, a flexible scraper 42 is provided between the arc plate 37 and the rolling cylinder 10. One side of the flexible scraper 42 is fixed on the outer wall of the arc plate 37, and the other side of the flexible scraper 42 is in contact with the inner wall of the rolling cylinder 10. During operation, when applying medicine to the rolling cylinder 10, medicine with high viscosity is easy to stick to the rolling cylinder 10. By providing the flexible scraper 42, the medicine on the outer wall of the rolling cylinder 10 is scraped and cleaned during the rolling process, which helps to prevent the medicine from sticking to the outer wall of the rolling cylinder 10.

[0050] As a further embodiment of the present invention, one-way limiting mechanisms are provided on both sides of the rolling cylinder 10. The one-way limiting mechanisms are used to limit the rolling cylinder 10 on the rear side of the massage head 1 in the direction of movement. The one-way limiting mechanism includes a rotating wheel 43, which is fixed on one side of the rolling cylinder 10 and is rotatably connected to the rotating column 11. Two ratchet teeth 44 are fixed on the rotating wheel 43. A pawl 45 is rotatably connected to the positioning plate 12. A torsion spring 46 is sleeved on the rotating shaft of the pawl 45. One end of the torsion spring 46 is fixed on the pawl 45, and the other end of the torsion spring 46 is fixed on the positioning plate 12. A limiting post 47 is provided on one side of the pawl 45 and is fixed on the positioning plate 12. During operation, through The ratchet 44 and pawl 45 are configured to unidirectionally limit the rotating wheel 43, thereby unidirectionally limiting the rolling cylinder 10 fixedly connected to the rotating wheel 43. This ensures that when the massage head 1 moves, only the rolling cylinder 10 on the front side of the movement direction rolls to apply the medicine, which is beneficial for applying the medicine to the massage area in advance before the massage. Furthermore, the rolling cylinder 10 on the rear side does not rotate, which helps reduce medicine waste. The ratchet 44 is configured so that when the pawl 45 positions the ratchet 44, the connecting hole 15 on the rolling cylinder 10 and the liquid permeation hole on the positioning cylinder 21 are staggered and closed. This helps to prevent the rolling cylinder 10 from being positioned when the connecting hole 15 and the liquid permeation hole are connected, thus preventing the continuous flow of liquid.

[0051] Working principle of this invention:

[0052] In use, the user manually holds the handle, bringing one side of the massage ball 9 on the massage head 1 into contact with the skin, and presses the handle 2 towards the side closest to the skin, making the massage ball 9 adhere tightly to the skin. Under the pressing action, the mounting shell 5 moves as a whole into the mounting groove 4 and compresses the first spring 6, causing the first spring 6 to generate elastic force. When the rolling cylinders 10 on both sides of the mounting shell 5 come into contact with the user's skin, the massage head 1 can be moved to perform a massage. The elastic squeezing force of the first spring 6 on the mounting shell 5 massages the user's skin, thus allowing the user to control the massage intensity of the massage head 1, avoiding excessive massage intensity that could cause injury to the body, and also avoiding insufficient massage intensity that would affect the massage effect; and by pressing... The massage head 1 has an internal cavity 13. Massage liquid is added into the cavity 13 through a medium adding mechanism, and then transported into the roller cylinder 10 through a medium conveying mechanism. The massage liquid flows out from the connecting hole 15 on the roller cylinder 10. During the massage, the roller cylinder 10 rolls on the user's skin, thereby spreading the massage liquid onto the user's body, which helps to enhance the massage effect. Alternatively, the medium adding mechanism can be connected to an external fumigation device to add fumigation vapor into the cavity 13. The fumigation vapor is then transported into the roller cylinder 10 through a medium conveying mechanism and flows out from the connecting hole 15 on the roller cylinder 10. During the massage, the user receives simultaneous fumigation, which helps to enhance the massage effect.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
