Description

Technical Field

[0001] This utility model relates to the field of massager technology, specifically a massager with a pressure sensor. Background Technology

[0002] With the fast pace of life, people are increasingly standing or sitting for long periods in their daily lives and work, which puts considerable pressure on the legs and easily leads to fatigue, soreness, and other discomfort. In response, some have designed massagers that provide vibration massage to the legs, which have become popular among consumers who frequently experience leg discomfort.

[0003] Early leg massagers had limited functionality, often using fixed massage modes and vibration intensities, making it difficult to meet the personalized needs of different users in different situations. Some users wanted a deep massage after exercise to relax tense muscles, but existing fixed-intensity massagers could not provide sufficient intensity; while other users only needed a gentle massage to relax during daily rest, and the fixed, higher intensity would make them feel uncomfortable.

[0004] With product improvements, some massagers have added multi-level adjustment functions, allowing users to manually select different massage intensities. However, this method presents several inconveniences in actual use. Firstly, users may already be in a relaxed state during a massage, and getting up to operate the adjustment buttons would interrupt this relaxation. Secondly, because everyone's perception and preference for intensity differs, it's difficult to accurately achieve the ideal massage intensity using preset levels. Furthermore, different users have varying leg muscle strength and flexibility, making a uniform level setting unsuitable for precisely matching each individual's needs. Utility Model Content

[0005] The purpose of this invention is to provide a massager with a pressure sensor, which aims to improve the shortcomings of existing massagers for legs in terms of the convenience, personalization, and intelligence of massage intensity adjustment.

A pressure sensor is arranged on the inner side of the front end of the left and right clamping arms. In a natural state, there is a certain gap between the pressure sensor and the main unit. The main unit includes a PCB board, a battery, and a vibration mechanism. The pressure sensor, battery, and vibration mechanism are all electrically connected to the PCB board. The PCB board controls the vibration intensity of the vibration mechanism in a positive correlation with the pressure value transmitted by the pressure sensor.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0024] like Figures 1-2As shown, a massager with a pressure sensor includes a main unit 1, which has a housing. A left clamping arm 2 and a right clamping arm 3 are symmetrically arranged on the left and right sides of the main unit 1, respectively. The left and right clamping arms 2 and 3 have identical structures, each including an elastic support 8 and a silicone pad 9 fitted onto the elastic support 8. During use, the silicone pad 9 directly contacts the skin of the leg, making the massager more comfortable. The rear ends of the elastic supports 8 of the left and right clamping arms 2 and 3 are connected to the housing of the main unit 1. The front ends of the left and right clamping arms 2 and 3 are suspended, forming elastic clamping arms. A pressure sensor 4 is arranged on the inner side of the front end of the left and right clamping arms 2 and 3. The pressure sensor 4 can be wrapped by an elastic structure such as a protruding hollow rubber block or hollow rubber ball. In its natural state, there is a certain gap between the elastic structure wrapping the pressure sensor 4 and the main unit 1. When using this invention, the main unit 1 is placed between a person's two lower legs or two thighs, with the two legs clamping the left clamping arm 2 and the right clamping arm 3 respectively. The inward clamping will deform the front ends of the left clamping arm 2 and the right clamping arm 3, pressing the elastic structure onto the outer shell of the main unit 1. This will cause the pressure sensor 4 to be subjected to force and detect the pressure value.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the host 1 includes a PCB board 5, a battery 6, and a vibration mechanism 7. The pressure sensor 4, battery 6, and vibration mechanism 7 are all electrically connected to the PCB board 5. The vibration mechanism 7 includes a drive motor 701 and an eccentric shaft 702. The drive motor 701 is fixedly installed inside the host 1. The eccentric shaft 702 includes an eccentric block portion and an eccentric rod portion. The eccentric block portion has an eccentric mounting hole, the central axis of which is parallel to but not coincident with the central axis of the eccentric block portion. The eccentric block portion is mounted on the output shaft of the drive motor 701 through the eccentric mounting hole, thus making the eccentric shaft 702 eccentrically mounted on the output shaft of the drive motor 701. Both the eccentric block portion and the eccentric rod portion are cylindrical structures. The eccentric rod portion is located on the eccentric block portion, and their central axes are parallel to but not coincident, i.e., the eccentric rod portion is eccentrically located on the eccentric block portion. The PCB board 5 has an MCU chip, and the battery 6 is used to power the pressure sensor 4, drive motor 701, and PCB board 5. The PCB board 5 can control the vibration intensity of the vibration mechanism 7 in a positive correlation with the pressure value transmitted by the pressure sensor 4. That is, the greater the pressure detected by the pressure sensor 4, the greater the vibration intensity generated by the vibration mechanism 7 controlled by the PCB board 5. When the vibration mechanism 7 vibrates, it drives the entire utility model to vibrate, thereby achieving leg massage. A switch button 15 is provided on the PCB board 5, which is the start / stop control switch of this utility model. The outer shell of the main unit 1 is provided with a button through hole adapted to accommodate the switch button 15.

[0026] like Figure 3 As shown, the main unit 1 is equipped with a charging female connector 10 for charging the battery 6, and the charging female connector 10 is electrically connected to the PCB board 5. A connector is provided on the outer casing of the main unit 1 at a position corresponding to the charging female connector 10, and the charging female connector 10 is located in this connector. A silicone plug 11 is detachably provided in the connector to protect the charging female connector 10. One end of the silicone plug 11 is hinged to the outer casing of the main unit 1, which effectively prevents the silicone plug 11 from being lost.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, a silicone piston 12 is provided at the front end of the main unit 1, and a pull rod 13 is installed on the eccentric rod portion of the eccentric shaft 702, which is connected to the silicone piston 12. When the drive motor 701 of the vibration mechanism 7 rotates, it drives the eccentric shaft 702 to rotate, which in turn pulls the silicone piston 12 back and forth through the pull rod 13, producing a vibration effect for localized massage of small parts of the human body. In addition, an external structure 14 is also provided at the front end of the main unit 1. The external structure 14 is located below the silicone piston 12. The external structure 14 can be extended to connect massage devices such as massage sticks through threaded connections, snap-fit ​​connections, and plug-in connections to achieve auxiliary massage and expand and enhance the function of this utility model.

[0028] The working principle of this invention is as follows: When in use, the main unit 1 is placed between a person's two lower legs or two thighs, with the legs clamping the left clamping arm 2 and right clamping arm 3 respectively. This inward clamping deforms the front ends of the left and right clamping arms 2 and 3, pressing the elastic structure firmly against the outer shell of the main unit 1. This causes the pressure sensor 4 to be subjected to force and detect the pressure value. The pressure sensor 4 transmits the detected pressure data to the PCB board 5. The PCB board 5 can control the vibration intensity of the vibration mechanism 7 in a positive correlation with the pressure value transmitted by the pressure sensor 4; that is, the greater the pressure detected by the pressure sensor 4, the greater the vibration intensity produced by the vibration mechanism 7. Thus, the user can conveniently adjust the vibration intensity, i.e., adjust the massage intensity, by adjusting the clamping force of the legs. When the user releases the left and right clamping arms 2 and 3, the pressure sensor 4 is no longer subjected to force, and the PCB board 5 automatically controls the vibration mechanism 7 to stop operating.

[0029] In summary, this utility model can be used for leg massage, and the massage intensity can be adjusted conveniently, personally, and intelligently, making it very convenient and comfortable to use, and providing users with a very good user experience.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
