[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0027] See Figure 1-6 As shown, a rowing machine for fitness exercise in this embodiment includes a handle 1, a transmission mechanism 2, a water ball 3, a base 4, a support frame 5, a hinge 6, a display mechanism 7, and a seat 8. The handle 1 is connected to the transmission mechanism 2. The handle 1 includes a connecting rod 13 and handles 11 connected to both ends of the connecting rod 13. A first electrode 12 is inserted into the handle 11, and the end of the first electrode 12 is electrically connected to a PCB 14. The PCB 14 is disposed in the connecting rod 13. A battery compartment 17 is disposed in the handle 11, and a battery 16 is installed in the battery compartment 17. The battery 16 supplies power to the PCB 14. The water ball 3 is provided with several LED beads of different colors. The PCB 14 controls the color of the LED beads according to the wireless signal emitted by the electrical signal of the first electrode 12.

[0028] The electrical signal from the skin surface of the hand is transmitted to the PCB14 via the first electrode 12. The PCB14 calculates the heart rate, transmits it wirelessly, and displays it on the display unit 7. Simultaneously, the color of the LEDs in the water balloon 3 is controlled according to the heart rate to indicate the user's health status.

[0029] To facilitate the display of the user's health status, the present invention is further configured as follows: when the heart rate detected by PCB14 is 60-90, the LED emits blue light; when the heart rate is 90-100, the LED emits light blue; when the heart rate is 100-110, the LED emits green light; when the heart rate is 110-120, the LED emits yellow light; when the heart rate is 120-130, the LED emits orange light; when the heart rate is 130-140, the LED emits red light; and when the heart rate is 140-150, the LED emits purple light. When red or purple light is detected, it is not suitable to continue exercising. Using different LED colors to distinguish the user's heart rate values ​​provides a more intuitive display of the user's health status.

[0030] To enhance user comfort, the present invention is further configured such that: the handle 11 includes a sheath 18 and a tube 19, the sheath 18 is fitted onto the tube 19, and the tube 19 is fixedly connected to the connecting rod 13. As the user's hand grips the sheath 18, a torque is generated between the hand and the sheath 18, causing the first electrode 12 to detach from the sheath 18. To strengthen the connection between the first electrode 12 and the sheath 18, the two ends of the first electrode 12 are respectively a first bent portion 123 and a second bent portion 124. The first bent portion 123 is provided with several spaced first claws 121 and second claws 122, which are perpendicularly connected to the first bent portion 123. To facilitate the transmission of electrical signals from the first electrode 12 to the PCB 14, a first hook 125 is connected to the second bent portion 124, and a second hook 126 is hung on the first hook 125. The second hook 126 is connected to a conductive plate 127, which is fixedly connected to the tube 19. Even if the first electrode 12 twists relative to the sheath 18, the engagement of the first hook 125 and the second hook 126, along with their elasticity, can overcome poor contact caused by slight movement of the first electrode 12, ensuring smooth transmission of electrical signals to the PCB 14.

[0031] To maintain close contact between the first electrode 12 and the skin of the hand, the present invention is further configured such that: a receiving groove is provided on the sheath 18; a spring pad 128 is bonded to the middle of the first electrode 12, and the spring pad 128 is bonded in the receiving groove. The spring pad 128 drives the first electrode 12 to move until the first electrode 12 protrudes from the spring pad 128 and abuts against the skin of the hand.

[0032] To reduce the displacement of the first electrode 12 caused by the twisting of the hand, the present invention further includes a conductive fiber bag 15 fitted onto the handle 11. When the handle 11 is gripped through the conductive fiber bag 15, even if the handle 11 slides and rotates relative to the conductive fiber bag 15, the electrical signal from the hand can still be transmitted to the PCB 14 through the conductive fiber bag 15 and the first electrode 12. The increased contact area between the first electrode 12 and the skin allows for closer transmission of changes in the hand's electrical signal. Simultaneously, it protects the skin from scratches caused by the first electrode 12.

[0033] To filter out ambient noise signals, the present invention further includes a second electrode 9 connected to the inner wall of the handle 11. The second electrode 9 is aligned with the first electrode 12 to form a capacitively coupled electrode, and then electrically connected to the PCB 14 via a coupling element 10. The coupling element 10 is a resistor, capacitor, diode, or inductor.

[0034] During exercise, sweating hands alter the coefficient of friction between the hand and the handle 11, making it difficult to grip the handle 11. To address this, the invention further includes several annular grooves 181 on the spring pad 128, each containing a water-absorbing agent. Preferably, the water-absorbing agent is packaged in a breathable annular bag and then placed around the annular grooves 181. The water-absorbing agent absorbs sweat from the hands, improving user comfort. After absorbing water, the water-absorbing agent expands, lifting the first electrode 12 for closer contact with the skin, resulting in a more accurate transmission of electrical signals.

[0035] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
