Multiple ball heads are arranged around the outer surface of the massage head, and a concave structure is formed in the center of the outer surface, with a suction cup inside the concave structure. By incorporating the massage head, suction cup, air pump, and solenoid valve, this utility model allows the massage head to adhere to the user's skin during massage. The suction cup is adhered to the user's skin surface by the negative pressure generated by the air pump, preventing the massage head from slipping and affecting the user's grip. Furthermore, the suction cup has a bowl-shaped structure with two non-deformable fixing ribs on its inner side. When negative pressure is generated inside the suction cup, the bowl-shaped suction cup collapses and deforms along the fixing ribs, causing the device to be subjected to a force towards the user, thereby adjusting the pressure between the massage head and the user.

Description

Technical Field

[0001] This utility model relates to the field of massage device technology, and in particular to a massage device with adjustable massage pressure. Background Technology

[0002] A handheld massager is a health care tool that includes a housing, a drive component inside the housing, and multiple massage blocks on the housing. The massage blocks are placed against the parts of the body that need massage, and the drive component causes the massage blocks to vibrate to massage the body. To facilitate the use of massagers, handheld massagers have been developed on the market. The advantages of this type of massager are that it is small, flexible, and easy to use.

[0003] Existing handheld massagers have some problems when in use. Because the massage head massages by moving, it can cause the user to lose their grip and slip during the movement, affecting the massage effect. In addition, the massage effect is limited by the user's pressure, and the massage intensity cannot be precisely controlled, resulting in limited effect.

[0004] Therefore, it is necessary to invent a massager with adjustable massage pressure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a massager with adjustable massage pressure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a massager with adjustable massage pressure, comprising a housing, a massage head at one end of the housing, a plurality of ball heads surrounding the outer surface of the massage head, a concave structure in the middle of the outer surface of the massage head, and a suction cup in the interior of the concave structure, the suction cup being bowl-shaped, a suction pump fixedly installed inside the housing, a fixing tube fixedly installed between the suction pump and the suction cup, an electromagnetic valve fixedly installed in the middle of the fixing tube, two annular fixing ribs fixedly installed on the inner wall of the suction cup, the fixing ribs being non-deformable, a plurality of deformable reinforcing ribs surrounding the outer wall of the suction cup, the reinforcing ribs being located between the two fixing ribs, a support ring rotatably provided on the inner wall of the massage head via a bearing, a plurality of support rods surrounding the inner side of the support ring, a plurality of sliding holes circumferentially opened at one end of the housing, the support rods being slidably installed within the sliding holes.

[0007] Preferably, one end of the support rod is fixedly provided with a transmission seat, and the transmission seat is slidably disposed inside the outer shell. Multiple connecting blocks are arranged around the outer side of the transmission seat, and multiple through slots are opened around the outer side of the outer shell. Each of the multiple connecting blocks is slidably disposed in the multiple through slots.

[0008] Preferably, a connecting ring is slidably provided on the outer side of the outer shell, and a plurality of connecting blocks are fixedly disposed on the inner side of the connecting ring.

[0009] Preferably, the outer side of the connecting ring is provided with a positioning sleeve that is rotatably provided by a bearing, and the positioning sleeve is threaded onto the outer side of the outer shell.

[0010] Preferably, a ring gear is fixedly provided on the inner side of the massage head, and the ring gear is rotatably located inside the outer shell.

[0011] Preferably, a drive motor is fixedly installed inside the outer casing, and a drive gear is fixedly installed on the output shaft of the drive motor, and the drive gear meshes with a ring gear.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by setting a massage head, suction cup, air pump, and solenoid valve, allows the massage head to fit in close contact with the user's skin during massage. The suction cup can be adsorbed onto the user's skin surface by the negative pressure generated by the air pump, thus preventing the massage head from sliding and affecting the user's grip. Furthermore, the suction cup is designed with a bowl-shaped structure, and two non-deformable fixing ribs are provided on the inner side of the suction cup. When negative pressure is generated inside the suction cup, the bowl-shaped suction cup collapses and deforms along the fixing ribs, so that the device is subjected to a force in the direction of the user, thereby adjusting the pressure between the massage head and the user. The degree of collapse and deformation of the suction cup can be controlled by controlling the opening of the solenoid valve, so as to control the massage intensity.

[0014] 2. This utility model, by setting a support ring, a transmission seat, a connecting ring, and a positioning sleeve, allows the support ring to support the massage head. The positioning sleeve can adjust the initial position of the massage head through the connecting ring and the transmission seat. When massaging different areas, the position of the massage head can be adjusted to ensure that the suction cup can better adhere to the surface of the user's skin. For example, when massaging the user's groin, back, or other concave areas, the position of the massage head can be adjusted so that the suction cup in the middle protrudes, so as to facilitate better adhesion and use.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-5 The massager shown includes an adjustable massage pressure device, comprising a housing 1, a massage head 2 at one end of the housing 1, a plurality of ball heads 3 surrounding the outer side of the massage head 2, a concave structure in the middle of the outer side of the massage head 2, and a suction cup 4 inside the concave structure, the suction cup 4 being a bowl-shaped structure, an air pump 5 fixedly installed inside the housing 1, a fixed tube 6 fixedly installed between the air pump 5 and the suction cup 4, and a solenoid valve 7 fixedly installed in the middle of the fixed tube 6. The power of the air pump 5 is constant. By controlling the opening and closing range of the solenoid valve 7, the rate at which air is drawn away from the inside of the suction cup 4 can be controlled, thereby controlling the deformation range of the suction cup 4 when a negative pressure space is formed inside the suction cup 4. It should be noted that the fixed tube 6 is a rigid tube, which is fixedly connected to the solenoid valve 7, and the solenoid valve 7 is fixedly installed inside the housing 1, which can ensure that the fixed tube 6 and the suction cup 4 will not rotate due to the rotation of the massage head 2.

[0023] The inner wall of the suction cup 4 is fixed with two annular fixing ribs 8, and the fixing ribs 8 are designed to be non-deformable. The suction cup 4 at the location of the fixing ribs 8 will not change. When a negative pressure area is formed inside the suction cup 4, the suction cup 4 between the two fixing ribs 8 will collapse and deform. The outer wall of the suction cup 4 is surrounded by multiple deformable reinforcing ribs 9, and the reinforcing ribs 9 are located between the two fixing ribs 8. The reinforcing ribs 9 are used to ensure that the suction cup 4 can recover its deformation after the air pump 5 stops working.

[0024] The inner wall of the massage head 2 is rotatably provided with a support ring 10 via a bearing. Multiple support rods 11 are arranged around the inner side of the support ring 10. Multiple sliding holes 12 are opened around one end of the outer shell 1. The support rods 11 are slidably disposed within the sliding holes 12. A transmission seat 13 is fixedly provided at one end of the support rod 11, and the transmission seat 13 is slidably disposed inside the outer shell 1. Multiple connecting blocks 14 are arranged around the outer side of the transmission seat 13. Multiple through slots 15 are opened around the outer side of the outer shell 1. Each of the multiple connecting blocks 14 can... The outer shell 1 is slidably provided in multiple through slots 15. A connecting ring 16 is slidably provided on the outer side of the outer shell 1. Multiple connecting blocks 14 are fixedly provided on the inner side of the connecting ring 16. A positioning sleeve 17 is rotatably provided on the outer side of the connecting ring 16 through a bearing. The positioning sleeve 17 is threaded on the outer side of the outer shell 1. When the positioning sleeve 17 rotates, it can slide along the surface of the outer shell 1 under the guidance of the thread, and drive the massage head 2 to slide through the connecting ring 16, connecting blocks 14, transmission seat 13, support rod 11 and support ring 10.

[0025] A ring gear 18 is fixedly provided on the inner side of the massage head 2, and the ring gear 18 is rotatably located inside the outer shell 1. A drive motor 20 is fixedly provided inside the outer shell 1, and a drive gear 19 is fixedly provided on the output shaft of the drive motor 20. The drive gear 19 meshes with the ring gear 18. It should be noted that the outer shell 1 is provided with a battery that provides energy to the drive motor 20, the air pump 5 and the solenoid valve 7, and a controller adapted to the drive motor 20, the air pump 5 and the solenoid valve 7 is also provided.

[0026] Working principle of this utility model:

[0027] When using this device, the user can hold the handle of the outer shell 1 and place the massage head 2 at one end of the outer shell 1 against the user's skin. At this time, the suction cup 4 inside the massage head 2 is in contact with the user's skin. Then, the air pump 5 is activated, and the air pump 5 draws air from inside the suction cup 4 through the fixed tube 6, so that the suction cup 4 is negatively pressured inside. Under the action of negative pressure, the suction cup 4 is attached to the user's skin surface to fix the device. Furthermore, by controlling the opening and closing range of the solenoid valve 7, the magnitude of the negative pressure inside the suction cup 4 can be controlled. When a negative pressure space is formed inside the suction cup 4, the suction cup 4 collapses and deforms along the fixed rib 8. When the magnitude of the negative pressure inside is adjusted, the collapse range of the suction cup 4 is adjusted, and the displacement range of the outer shell 1 caused by the deformation of the suction cup 4 is adjusted. Therefore, the pressure of the massage head 2 connected to the outer shell 1 on the user's skin is adjusted, thereby achieving the effect of adjusting the massage pressure.

[0028] After the suction cup 4 completes the adsorption, the drive motor 20 is started. The drive motor 20 drives the ring gear 18 to rotate through the drive gear 19. The ring gear 18 drives the massage head 2 to rotate. The massage head 2 drives the ball head 3 to move, so as to massage the user's skin surface.

[0029] When massaging different parts of the user's body, the initial position of the massage head 2 can be adjusted to ensure the suction effect of the suction cup 4. When massaging protruding parts such as the user's elbows and knees, the position of the massage head 2 can be adjusted away from the suction cup 4 to ensure the adhesion between the massage head 2 and the user's elbows and knees after the suction cup 4 is attached. When massaging recessed parts such as the user's back of the legs and back, the position of the massage head 2 can be adjusted towards the suction cup 4 to ensure the adhesion between the massage head 2 and the user's back of the legs and back after the suction cup 4 is attached.

[0030] When adjusting the position of the massage head 2, the positioning sleeve 17 is rotated so that it slides along the surface of the outer shell 1 under the action of the thread. The positioning sleeve 17 can drive the massage head 2 to slide through the connecting ring 16, connecting block 14, transmission seat 13, support rod 11 and support ring 10 to achieve the effect of adjusting the initial position of the massage head 2.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
