Description

Technical Field

[0001] The utility model belongs to the technical field of health-care massage equipment, and particularly relates to a novel negative pressure massager. Background Art

[0002] With the continuous improvement of people's living standards, people's health awareness has also been greatly improved. More and more health massage products have been used. Common massage devices use motor mechanical vibration to massage the human body. Not only is the massage form relatively stiff, but the vibration is also likely to cause a certain degree of damage to the human muscles.

[0003] The Chinese patent publication number is CN116172848A, and the patent name is "An air pulse wave massager." The housing opening of the skeleton shell is provided with a rigid head cavity, which has a pulse airflow cavity formed therethrough. A spring-shaped silicone airbag is disposed within the skeleton shell. The upper end of the spring-shaped silicone airbag is open and communicates with the lower end of the rigid head cavity, forming a pulse airflow path between the spring-shaped silicone airbag and the pulse airflow cavity.

[0004] Although it can reduce the damage to human muscles to a certain extent, it requires a spring-shaped rubber airbag and a dual-axis motor to achieve this, which not only greatly increases the processing cost, but also its spring-shaped silicone airbag is prone to aging after long-term use, thereby affecting the smoothness of the massage. At the same time, it also has the problems of high noise and unstable strength, which will also affect the effectiveness of the massage, so its applicability and practicality are limited.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0043] See Figures 1 to 4 As shown, a new negative pressure massager comprises a housing 1 with an inner cavity, a massage structure 2 disposed within the housing, a massage hole 3 formed at the massage end of the housing, and a massage head 4 disposed within the massage hole. In this embodiment, the massage head is a circular silicone massage head, the center of which is connected to the piston cylinder. It is primarily used for contacting the massage area. The housing comprises a first half-shell 11, a second half-shell 12, and a top gland 13. The first and second half-shells are secured by screws. This structure improves installation convenience, and the screw fixation also ensures smooth installation.

[0044] In actual use, the massage structure 2 includes a power supply battery 21, a control circuit board 22, a control motor 23, a transmission structure 24, a piston cylinder 25, and a piston body 26. The power supply battery is primarily used for power supply, the control motor is a conventional structure in the prior art, and is primarily used to drive the massage operation. The control circuit board is a conventional structure in the prior art, and is primarily used to receive control signals and drive the motor to start. During installation, the end of the piston cylinder is fixed to the top of the massage head; the piston body is fixed to the bottom of the transmission structure and is movably disposed within the piston cylinder. In this embodiment, a rubber ring is provided on the outer wall of the piston body, which is a common structure in the prior art and is not described in detail. The massage operation is achieved primarily by raising and lowering the piston body within the piston cylinder, thereby generating a certain negative pressure at the position of the massage head, causing the massage head to be squeezed and deformed.

[0045] Furthermore, in actual use, the top end of the transmission structure is connected to the main shaft of the control motor, and the control circuit board is connected to the control motor. The control motor operates, driving the piston body up and down within the piston cylinder via the transmission structure. The power supply battery is connected to the control circuit board and the control motor. Furthermore, in this embodiment, the transmission structure 24 includes a transmission connecting piece 241, a transmission support piece 242, and a guide shaft 243. The transmission support piece is L-shaped, and both the transmission connecting piece and the transmission connecting piece are metal structures.

[0046] During installation, a mounting block 17 is fixed on the main shaft of the control motor, and a connecting cam 18 is provided on the side of the mounting block away from the main shaft of the control motor; through the mounting block, the connecting cam can be staggered with the main shaft of the control motor to form an eccentric setting, so when the main shaft of the control motor rotates, the connecting cam will move on a circular ring, thereby driving the transmission connecting piece to rise and fall.

[0047] In actual application, a vertical guide hole 5 is provided on the transmission connecting plate, and a transverse strip groove 6 is provided on the upper part of the transmission connecting plate; the connecting cam is movably arranged in the transverse strip groove; because the connecting cam is in the transverse strip groove, it has a certain buffer space, thereby ensuring the effectiveness and smooth reliability of the rotation of the connecting cam on the circular trajectory.

[0048] In this embodiment, there can be one or two guide shafts, which mainly ensure that the transmission connecting piece will not shift or tilt when it is lifted or lowered, thereby ensuring the effectiveness of the lifting. During installation, the guide shaft is arranged in the vertical guide hole, and the two ends of the guide shaft are fixed in the shell; the upper part of the transmission support piece is fixed to the lower part of the side of the transmission connecting piece by screws, and the top of the piston body is fixed to the bottom end of the transmission support piece; the control motor rotates to drive the transmission connecting piece to rise and fall on the guide shaft, and makes the transmission support piece rise and fall synchronously.

[0049] In actual use, to enhance the smoothness and reliability of the control motor installation, the inner wall of the second half-shell is provided with a motor mounting slot 7 and several guide shaft support protrusions 8. During installation, the control motor is inserted and positioned within the motor mounting slot, and the ends of the guide shaft are positioned within the upper limit positions of the guide shaft support protrusions. This structure ensures smooth installation of the guide shaft and facilitates assembly and disassembly operations.

[0050] In this embodiment, the top gland is provided with snap hooks 9 along the edge of its mounting surface. The top gland fits over the top of the first and second half shells and is locked in place by the snap hooks. The top gland facilitates battery replacement and improves the overall aesthetics. The snap hooks facilitate opening and closing, making operation more convenient.

[0051] The outer wall of the piston cylinder is integrally formed with a mounting lug 10, which is fixed to the interior of the housing by screws. Through the above structure, the position of the piston cylinder after installation can be guaranteed to be stable and reliable.

[0052] To enhance operational convenience, the housing is also equipped with control buttons 14 connected to the control circuit board. Furthermore, to enhance the aesthetics of the main body, a decorative silicone sleeve 15 is provided on the outside of the housing. A limit slot 16 is provided on the upper portion of the housing's outer wall. During installation, the decorative silicone sleeve is fitted over the housing's outer wall, with the top of the sleeve snapping into the limit slot to position it. This improves installation convenience and ensures smooth and reliable installation. The decorative silicone sleeve is shaped like a flower. Other shapes are also possible.

[0053] Its working principle is briefly described as follows: the control circuit board is a conventional control circuit board, which is the core control component and is mainly responsible for receiving signals and converting them into motor control signals; when the control button is started, the control circuit board receives the control signal and makes the control motor move. When the main shaft of the control motor rotates, it drives the mounting block and the connecting cam to rotate together. Since the connecting cam is staggered and eccentrically arranged with the main shaft of the control motor, the connecting cam will move in the transverse strip groove on the transmission connecting piece when rotating, and drive the transmission connecting piece to rise and fall under the limit of the guide shaft, and drive the transmission support piece to rise and fall synchronously, so that the piston body rises and falls in the piston cylinder. During massage, after the massage head is attached to the massage position, when the piston body rises and falls in the piston cylinder, negative pressure will be generated, thereby squeezing and deforming the massage head at the massage position to achieve the massage operation.

[0054] The utility model has positive effects: the structure of the utility model is reasonably set up, which not only makes the operation more stable, but also has lower requirements for the control motor, which is beneficial to reducing processing costs, and the use of the piston cylinder and the piston body can also ensure the stability of operation, and it is not easy to be damaged during long-term use, which is beneficial to improving the service life; and the overall structure has low noise during use, strong massage force, and strong suction, which is beneficial to improving the massage effect, convenient operation, strong applicability and good practicality.
