Example 2:

the working principle of the intelligent tennis racket capable of monitoring the respiration, the heartbeat and the heart rate is as follows:

when a user uses the tennis racket to play tennis, the power supply 44 is firstly switched on, the monitoring ring 43 is worn on the wrist of the user, and the monitoring ring 43 has an anti-falling effect, so that in the playing process, the breath, the heartbeat and the heart rate of the user can be monitored by the monitoring ring 43 and are sent to the receiver 45 through the electrifying wire 42, the receiver 45 is sent to the processor 46, various data are displayed in the display 41 through the operation of the processor 46, the observation by the user is facilitated, when the user has severe exercise and the heartbeat and the heart rate of the user are too high, the processor 46 starts the buzzer 47 to vibrate the main body 1 to draw the attention of the user, and the display 41 informs the user of paying attention to the body state so that the user can make adjustment in time. Then, a user holds the handle 22 with a hand, the anti-slip pad 24 on the surface of the handle 22 contacts the skin of the hand, the air outlets 23 are distributed in the hand covering range, the anti-slip pad 24 can increase the friction force and the flexibility of the contact surface, and the holding stability and the holding hand feeling are improved. When a user waves the main body 1 to hit tennis balls, air flow is generated by high-speed movement of the main body 1 and the grab handle 22, the air flow enters the grab handle 22 through the air inlet hole 21, a part of the air flow directly flows out of the air outlet 23 to blow the palm of the user, and the air flow is wider in air flow coverage range through the guidance of the guide grooves 25 which are arranged in a criss-cross mode, so that the palm of the user can feel cool in the process of waving the main body 1, in the process, the slider 6565 slides along the transmission shaft 62 by the force of the user shaking the main body 1, the first spring 64 is compressed, the screw 68 moves along with the slider 65, the screw 68 slides in the sliding groove 66 on the side wall of the transmission shaft 62 and in the guide fin 26, meanwhile, the sliding of the screw 68 drives the fan 67 to rotate, the rotation of the fan 67 accelerates the air flow entering from the air inlet hole 21, so that the air flow rapidly flows in the grab handle 22, the airflow is ejected from the air outlet 23 by the guide of the guide fin 26 and then guided by the guide groove 25, so that a user can feel cool in the palm in the process of swinging the main body 1; the slide 65, when sliding along the shaft 62, hits the stop 63, causing the shaft 62 to move upwards according to the direction of fig. 2, which is the same below, due to the threaded connection between the transmission shaft 62 and the rotating post 61, the transmission shaft 62 moves upwards to rotate the rotating post 61, the rotating post 61 drives the transmission gear 69 and the second bevel gear 69a to rotate, the transmission gear 69 drives the stud 58 to rotate, the stud 58 moves downwards while meshing with the transmission gear 69 to rotate, the stud 58 drives the pull plate 57 to move downwards, the pull plate 57 pulls the longitudinal ball net 53 to tighten the longitudinal ball net 53, and the ratchet gear 71 rotates, the outer wall of the ratchet gear 71 will collide and press the inclined surface of the limit teeth 72 in the rotating direction, so that the limit teeth 72 slide into the main body 1, the second spring 73 is compressed, the blocking of the limiting teeth 72 is lost, and the ratchet wheel 71 can freely rotate in the main body 1 without interfering the rotation of the rotating column 61; meanwhile, the rotating column 61 drives the second bevel gear 69a to rotate, the second bevel gear 69a drives the first bevel gear 56 to rotate, the first bevel gear 56 drives the threaded sleeve 55 to rotate, the threaded sleeve 55 enables the two tightening bolts 54 to move towards two sides, the tightening bolts 54 open the bottom end of the expanding ring 52, the top end of the expanding ring 52 rotates around the rotating shaft 51, the expanding ring 52 moves towards two sides to tighten the transverse net 53, the transverse net 53 is tightened, after the sliding process of the sliding block 65 is finished, the sliding block 65 slides downwards along the transmission shaft 62 under the reaction force of the first spring 64, the sliding block 65 drives the screw rod 68 to slide downwards in the sliding groove 66 and the flow guide fin 26, meanwhile, the screw rod 68 drives the fan 67 to rotate to continue accelerating the air flow, and thus the fan 67 can always accelerate the air flow in the process of swinging the main body 1 by a user. When the slider 65 is reset, the rotating column 61 may rotate in the opposite direction, and at this time, when the ratchet wheel 71 stops rotating, the limiting teeth 72 lose the contact of the outer wall of the ratchet wheel 71, and at the same time, slide out of the main body 1 under the reaction force of the second spring 73, and contact the outer wall of the ratchet wheel 71 again, and the ratchet wheel 71 will contact the side wall of the limiting teeth 72 when rotating in the opposite direction, so that the limiting teeth 72 cannot be squeezed, and thus the limiting teeth 72 will prevent the ratchet wheel 71 from rotating, thereby preventing the rotating column 61 from rotating in the opposite direction, and the net 53 will not loosen again; in the user's motion, its palm can produce a lot of sweat, the sweat can be through the water conservancy diversion effect of guiding gutter 25, flow into inside the grab handle 22 from air outlet 23, and finally flow in absorb water the layer 32, absorb water the box 31 and can absorb and pin the sweat, prevent that the sweat from flowing at will, the motion finishes the back and rotates and take out and absorb water the layer 32, press and absorb water the box 31, the sweat extrusion in the layer 32 that will absorb water, then rotate the layer 32 that absorbs water again, will absorb water the layer 32 and install back in the grab handle 22. The device has the advantages of helping the palm to dissipate heat and perspire and automatically tightening the net wires.

In summary, the invention provides an intelligent tennis racket capable of monitoring respiration, heartbeat and heart rate, wherein a sliding block is driven to slide by force generated by a user swinging a main body, so as to drive a screw rod to slide and a rotating column to rotate, the screw rod can drive a fan to rotate by sliding, so as to accelerate airflow flow inside a grab handle, and the special shape design of a flow guide fin is utilized to improve the ejection amount of airflow from an air outlet, so as to bring visual refreshing and cooling feeling to hand skin, accelerate palm sweat evaporation, keep a palm in a comfortable state, and then expand airflow coverage area through the guidance of a flow guide groove, so that the efficiency of perspiration and heat dissipation is greatly improved; the rotation of rotating the post can drive the fine motion of tightening structure to tighten the net, avoid the net to take place deformation and not hard up and the not good and influence tennis experience scheduling problem of batting effect that causes at the in-process of batting for a long time. The invention has the advantages of helping the palm to dissipate heat and perspire and automatically tightening the network cable.
