DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described in detail below 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 making a clearer and more precise definition of the protection scope of the present invention.

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

[0028] The electrical signals from the hand skin surface are transmitted to the PCB 14 via the first electrode 12. The PCB 14 calculates the heart rate and transmits it wirelessly to the display 7. Simultaneously, the light color of the light beads in the water ball 3 is controlled according to the heart rate, providing a user with an indication of their health status.

[0029] To facilitate displaying the user's health status, the present invention further configures the following configuration: when the PCB 14 detects a heart rate of 60-90, the lamp emits blue light; when it detects a heart rate of 90-100, the lamp emits aqua light; when it detects a heart rate of 100-110, the lamp emits green light; when it detects a heart rate of 110-120, the lamp emits yellow light; when it detects a heart rate of 120-130, the lamp emits orange light; when it detects a heart rate of 130-140, the lamp emits red light; and when it detects a heart rate of 140-150, the lamp emits purple light. If red or purple light appears, it is not appropriate to continue exercising. Using different lamp bead colors to distinguish the user's heart rate values more intuitively displays the user's health status.

[0030] To enhance user comfort, the present invention further provides that the handle 11 includes a sheath 18 and a tube 19. The sheath 18 is sleeved onto the tube 19, which is fixedly connected to the connecting rod 13. When the user grips the sheath 18, a torque is generated between the hand and the sheath 18, causing the first electrode 12 to separate from the sheath 18. To strengthen the connection between the first electrode 12 and the sheath 18, the first electrode 12 has a first bent portion 123 and a second bent portion 124 at each end. The first bent portion 123 is provided with a plurality of spaced first and second claws 121 and 122, each of which is perpendicularly connected to the first bent portion 123. To facilitate the first electrode 12 to transmit electrical signals to the PCB 14, a first hook 125 is connected to the second bent portion 124. A second hook 126 is attached to 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 first hook 125 and the second hook 126 are engaged with each other and are elastic, thus overcoming the poor contact caused by slight movement of the first electrode 12 and 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 further comprises: a receiving groove is provided on the sheath 18; a spring pad 128 is bonded to the center of the first electrode 12 and is bonded to 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 contacts the skin of the hand.

[0032] To reduce the displacement of first electrode 12 caused by twisting of the hand, the present invention further provides a conductive fiber bag 15 overlying handle 11. By gripping handle 11 through conductive fiber bag 15, even if handle 11 and conductive fiber bag 15 slide and rotate relative to each other, electrical signals from the hand can still be transmitted through conductive fiber bag 15 and first electrode 12 to PCB 14. First electrode 12 increases the contact area with the hand skin, more closely transmitting changes in the hand's electrical signals to first electrode 12. This also protects the hand skin from scratches caused by first electrode 12.

[0033] To filter out cluttered electrical signals in the environment, the present invention further provides that: a second electrode 9 is connected to the inner wall of the handle 11. After the second electrode 9 is aligned with the first electrode 12 to form a capacitive coupling electrode, it is 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, the user's hands sweat, which changes the friction coefficient between the hand and the handle 11, making it difficult to grip the handle 11 during exercise. The present invention further provides that the spring pad 128 is provided with a plurality of annular grooves 181, each containing a water absorbent. Preferably, the water absorbent is packaged in an annular breathable bag and then placed within the annular grooves 181. The water absorbent absorbs sweat from the hand, providing greater comfort for the user. After absorbing water, the water absorbent expands, lifting the first electrode 12 for closer contact with the hand skin, and transmitting a more realistic electrical signal.

[0035] The above embodiments are only for illustrating the technical concept and features of the present invention. Its purpose is to enable people familiar with this technology to understand the content of the present invention and implement it. It cannot be used to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
