The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] like Figures 1 to 7 As shown, a hair blowing mechanism of a pull rod includes a pull rod body 1, a guiding device 2, an air inlet 3, an air outlet 4, and a grip 5. The pull rod body 1 has a cavity 11, and the air inlet 3 and the air outlet 4 are respectively located at the two ends of the cavity 11. The guiding device 2 is placed in the cavity 11 and is used to guide the air from the air inlet 3 to the air outlet 4. The grip 5 is provided on the outer edge of the pull rod body 1, and the air outlet 4 blows air toward the grip 5.

[0031] See Figures 2 and 3As shown, the cavity 11 is equipped with a power supply 12, and the power supply 12 is electrically connected to the guide device 2. In this embodiment, the power supply 12 is installed in the cavity 11, and the guide device 2 is powered by the power supply 12, so that air blowing can be performed without an external power supply 12. In a preferred embodiment, the power supply 12 can be installed between the air inlet 3 and the guide device 2 to ensure the stability of the air intake; the power supply 12 can also be installed at the air outlet 4 so that the guide device 2 blows air toward it to play a heat dissipation role. Furthermore, the battery can be a polymer battery, which can be arranged along the air outlet 4 to make full use of the internal space of the pull rod body 1.

[0032] An end cap 13 is provided at one end of the pull rod body 1, and the end cap 13 is provided with an electrical connection element 131, which is electrically connected to the power supply 12; in this embodiment, the electrical connection element 131 is used in conjunction with the power supply 12 to connect to the power, and then during use, the pull rod body 1 and the end cap 13 can be used in conjunction with the fitness equipment to charge or directly connect to the power.

[0033] The power connection element 131 includes a power contact 131a, with magnetic elements 131b disposed on both sides of the power contact 131a. The power contact 131a is electrically connected to the power source 12 and is used to charge the power source 12. In this embodiment, the power contact 131a and the magnetic elements 131b are used to provide a charging slot on the fitness device for direct charging of the power connection element 131.

[0034] The guiding device 2 is a high-speed guiding device 2. In this embodiment, the high-speed guiding device 2 is used as the guiding device 2 for wind guidance, which has high wind pressure and high sweat drying efficiency.

[0035] See Figure 6 As shown, the high-speed guide device 2 includes a shell 21, a shaft assembly 22, a stator assembly 23, a rotor assembly 24, and fan blades 25. The shell 21 includes a fixed outer ring 211 placed in the cavity 11, and a fixed inner ring 212 integrally connected to the fixed outer ring 211. There is an air duct 213 between the fixed inner ring 212 and the fixed outer ring 211. The air duct 213 cooperates with the fan blades to blow air. Under the cooperation of the rotor assembly 24 and the stator assembly 23, the shaft assembly 22 drives the fan blades 25 to rotate at high speed for high-speed blowing. In further improvements, the shell 21 is integrally formed, and the fixed inner ring 212, the fixed outer ring 211 and the air duct 213 are all integrally formed, and the structure is reliable.

[0036] The stator assembly 23 is installed at one end of the fixed inner ring 212, and the shaft assembly 22 is provided with a rotating shaft 221, which extends to the stator assembly 23. The rotor assembly 24 is sleeved on the rotating shaft 221 and cooperates with the stator assembly 23. The fan blades 25 are connected to the rotating shaft 221, and the fan blades 25 are connected to the air duct 213. In this embodiment, the fan blades 25 are connected to the air duct 213 under the action of the rotating shaft 221 to blow air. In a further preferred embodiment, the shaft assembly 22 includes a copper sleeve 222 placed on the fixed inner ring 212 and a bearing 223 provided in the copper sleeve 222. The rotating shaft 221 passes through and is connected to the bearing 223; through the cooperation of the bearing 223 and the copper sleeve 222, it is stable during high-speed rotation, thereby ensuring the stability of high-speed blowing.

[0037] There are multiple boosting plates 213a evenly distributed in the air duct 213 in an annular direction. The boosting plates 213a are arranged in a spiral shape. In this embodiment, the spiral boosting plates 213a are arranged to enhance the boosting of the incoming air, and the incoming air boosting is stable and the air outlet efficiency is high.

[0038] The air inlet portion 3 includes a plurality of air inlet holes 31 evenly distributed on the pull rod body 1. In this embodiment, the air inlet portion 3 formed by the plurality of air inlet holes 31 also forms a filter structure, and the air intake is stable.

[0039] The air outlet portion 4 includes an air guide cover 41 connected to one end of the pull rod body 1. The air guide cover 41 is provided with an air outlet surface 42 facing the grip portion 5. The air outlet surface 42 is provided with an air outlet groove 43. The air outlet groove 43 discharges air toward the grip portion 5. In this embodiment, the air guide cover 41 is used to diffuse and guide the wind, and the wind is divided and guided out from the air outlet surface 42 and the air outlet groove 43.

[0040] In the above embodiment, the air guide cover 41 is provided with a frame portion connected to the pull rod body 1 .

[0041] In another embodiment, the air outlet surface 42 is a vertical surface, an outward convex arc surface, or an inward concave arc surface. The vertical air outlet surface 42 can correspond to a flat air outlet, the outward convex arc surface can diffuse the air outlet and stabilize the air outlet, and the inward concave arc surface can increase the inward direction.

[0042] See Figures 2 and 3 As shown, the air outlet slot 43 includes an air outlet gap 431 circumferentially opened on the air outlet surface 42, and air outlet holes 432 located on the periphery of the air outlet gap 431. The air outlet holes 432 are inclined, and the inner diameter of the air outlet gap 431 is close to the periphery of the pull rod body. In this embodiment, the air can be discharged 360° through the circumferential connection of the air outlet gap 431, and the holding position can be blown and dried in all directions; in addition, the air outlet hole 432 is also provided, and is opened in an oblique shape. The oblique shape can be inclined outward for blowing air on the back or side of the hand; inclined inward for blowing air on the palm of the hand to dry the sweat on the palm of the hand.

[0043] The air guide cover 41 is hemispherical and has a booster 411 inside. The booster 411 is conical and gradually shrinks from the air guide cover 41 toward the guide device 2. In this embodiment, a booster 411 is provided inside the air guide cover 41. The booster 411 can boost the air outlet to enhance the air outlet effect. Moreover, it has a conical structure, so the air guide is more stable and the air outlet efficiency is higher.

[0044] In another embodiment, a plurality of booster plates 411a are evenly distributed around the periphery of the booster 411, and the booster plates 411a are spirally arranged around the periphery of the booster 411; a spiral wind groove formed by the booster plates 411a is also provided to guide the wind, so that the gripping portion 5 can be blown 360° to keep the gripping portion 5 dry.

[0045] See Figure 7 As shown, in a preferred embodiment, a placement cavity is provided in the booster 411 , and a power source 12 is installed in the placement cavity. The power source 12 is a battery, which can fully utilize the space of the pull rod body 1 .

[0046] In another preferred embodiment, the air inlet portion 3 is an air inlet provided at the bottom of the pull rod body 1 , thereby increasing the air inlet area.

[0047] The present invention provides a guide device 2 within the pull rod body 1, and guides the air sucked by the air inlet 3 to the air outlet 4 through the guide device 2 to blow air toward the grip 5. This solves the problems of the fitness pull rod becoming slippery and easily breeding bacteria after the user sweats, allowing the user's hand to remain dry and comfortable during fitness use, without slipping and thus without breeding bacteria. Specifically, the pull rod body 1, the guide device 2, the air inlet 3, the air outlet 4, and the grip 5 are provided. The pull rod body 1 has a cavity 11 therein, with the air inlet 3 and the air outlet 4 located at the two ends of the cavity 11, respectively. The guide device 2 is placed in the cavity 11 and is used to guide air from the air inlet 3 to the air outlet 4, and the air outlet 4 blows air toward the grip 5. During use, the user holds the grip portion 5, and air is blown toward the hand through the air outlet portion 4 under the action of the guiding device 2, so that the user's hand remains dry and comfort is improved; the air inlet portion 3 and the air outlet portion 4 are respectively at the two ends of the pull rod body 1, which can increase the user's grip space and prevent the user's hand from blocking the air inlet portion 3.

[0048] The above embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
