DETAILED DESCRIPTION OF THE EMBODIMENTS

The technical solutions in the embodiments of the present disclosure are clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely some embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without making creative efforts shall fall within the protection scope of the present disclosure.
Referring to FIG. 2 to FIG. 6 , in an embodiment of the present disclosure, a handheld accessory with good air inlet performance includes a handheld accessory body 1. The handheld accessory body 1 includes a grip portion 2 and a folding portion 3 rotatably connected to one end of the grip portion 2.
The folding portion 3 is of a hollow structure, and a motor fan assembly 4 is arranged in the folding portion. A first air outlet 5 is provided in one end of the folding portion 3 away from the grip portion 2; a first air inlet 6 is provided in one end of the folding portion 3 that is connected to the grip portion 2; and the first air inlet 6, the inside of the folding portion 3, and the first air outlet 5 form a fluid channel that is from the first air inlet 6 to the first air outlet 5 in sequence and is arranged in the motor fan assembly 4 in a penetrating manner.
In the technical solution of the present disclosure, the handheld accessory body 1 can correspond to a hand shank portion of a warm-air comb or a high-speed hair dryer. The handheld accessory body 1 is divided into the grip portion 2 and the folding portion 3, both of which can be of cylindrical structures. The handheld accessory body 1 has an unfolded state and a folded state. In the unfolded state, the folding portion 3 is connected to the grip portion 2 to form a shape of 1. In the folded state, the folding portion 3 is connected to the grip portion 2 to form a shape of 7, L, or rightwards inverted L. By rotatably connecting the folding portion 3 to one end of the grip portion 2, a user can hold the grip portion 2 according to an actual need and adjust an angle of the folding portion 3 relative to the grip portion 2. Corresponding levels can be provided at connecting ends of the grip portion 2 and the folding portion 3, to fix the folding portion 3 after angle adjustment.
Based on the above, the motor fan assembly 4 is arranged in the folding portion 3, so that an air supply function is achieved through the motor fan assembly 4. Furthermore, the first air inlet 6 is provided in a surface of one end of the folding portion 3 corresponding to the grip portion 2; and the first air outlet 5 is correspondingly provided in the other end of the grip portion 2. Therefore, the first air inlet 6, the inside of the folding portion 3, and the first air outlet 5 can form a fluid channel that is from the first air inlet 6 to the first air outlet 5 in sequence and is arranged in the motor fan assembly 4 in a penetrating manner. Thus, after the folding portion 3 is folded relative to the grip portion 2, since the motor fan assembly 4 and the first air inlet 6 are both arranged at the folding portion 3, the fluid does not flow through a joint between the folding portion 3 and the grip portion 2, and a flowing path of the fluid does not need to be changed. Thus, the problem of the impact on an air volume caused by wind loss due to fluid obstruction is effectively avoided.
In an embodiment of the present disclosure, the first air outlet 5 is arranged along a central axis of the folding portion 3 on a port of one end of the folding portion 3 away from the grip portion 2, and the first air inlet 6 is provided in one side surface of one end of the folding portion 3 connected to the grip portion 2.
By the arrangement of the first air outlet 5 on the port of the grip portion 2, it is beneficial for uniform air discharging from the first air outlet 5 at the folding portion 3. The first air inlet 6 is provided in one side surface of one end of the folding portion 3 connected to the grip portion 2, so that an air inlet end of the handheld accessory body 1 is on the folding portion 3, namely, the flowing path of the fluid is on the folding portion 3. Therefore, after the folding portion 3 is folded, the fluid does not need to change its flowing path, thereby effectively avoiding the problem of the impact on an air volume caused by wind loss due to fluid obstruction after folding.
In an embodiment of the present disclosure, connecting end surfaces of the folding portion 3 and the grip portion 2 are oblique-incision-shaped, so that connecting ends of the folding portion 3 and the grip portion 2 are respectively formed into a first oblique end 7 and a second oblique end 8; and

- the first air inlet 6 is arranged on a side surface of the first oblique end 7 in a curved transition manner, so that the first air inlet 6 extends to two sides of the side surface of the first oblique end 7.

Since the connecting end surfaces of the folding portion 3 and the grip portion 2 are oblique-incision-shaped, the contact end surfaces of the first oblique end 7 and the second oblique end 8 can be parallel to each other and can rotate relative to each other, thereby facilitating the folding of the handheld accessory body 1. The first air inlet 6 can extend to the two sides of the side surface of the first oblique end 7 according to the shape of the first oblique end 7, so that an area of the first air inlet 6 can be effectively enlarged, thereby effectively ensuring the air inlet volume.
In an embodiment of the present disclosure, an annular boss 9 is arranged on an end surface of the first oblique end 7 in a protruding manner; an annular sliding chute 10 is arranged along a circumferential surface of the annular boss 9 in a recessed manner; an annular opening 11 corresponding to the annular boss 9 is provided in an end surface of the second oblique end 8; and an annular clamping block 12 corresponding to the annular sliding chute 10 is arranged along an edge of the annular opening 11 in a protruding manner.
By the clamped sliding fit between the annular clamping block 12 and the annular sliding chute 10, the rotatable connection between the folding portion 3 and the grip portion 2 is achieved. A corresponding limiting block can be arranged on the annular boss 9 to limit a rotation angle of the folding portion 3 relative to the grip portion 2.
In an embodiment of the present disclosure, the grip portion 2 is of a hollow structure; a second air inlet 13 is provided in one end of the grip portion 2 away from the folding portion 3; and a second air outlet 14 is provided in one end of the grip portion 2 connected to the folding portion 3.
Namely, the second air inlet 13 is provided in a lower end of the grip portion. Regardless of whether the handheld accessory body 1 is in the unfolded state or the folded state, the second air inlet 13 can achieve an effect of assisting air intake, which is beneficial for the overall air inlet volume.
In an embodiment of the present disclosure, a control module 15 is arranged in the grip portion 2; a heating module 16 is further arranged in the folding portion 3; the heating module 16 is close to one end of the first air outlet 5; and the motor fan assembly 4 is close to one end of the first air inlet 6.
The heating module 16 and the motor fan assembly 4 are both electrically connected to the control module 15.
The control module 15 is a circuit board known to those of ordinary skill in the art, and the heating module 16 is a heating wire or mica sheet known to those of ordinary skill in the art. The control module 15 is arranged in the grip portion 2, so that it is easy to carry out an operation on the grip portion 2 through corresponding control buttons. Meanwhile, the air intake of the second air inlet 13 is also conducive to heat dissipation of the control module 15 during operation. The heating module 16 is arranged in the folding portion 3, so that it is easy to blow hot air in a timely manner at the first air outlet 5.
In an embodiment of the present disclosure, a Hall element (not shown) electrically connected to the control module 15 is further arranged in the grip portion 2, and a magnetic component (not shown) corresponding to the Hall element is arranged at a joint between the grip portion 2 and the folding portion 3. Thus, due to the cooperation between the Hall element and the magnetic component, air outlet pressures are different when the handheld accessory body 1 is in the unfolded state and the folded state.
When the handheld accessory body 1 is in different states, a relative position between the grip portion 2 and the folding portion 3 changes. Since the Hall element is arranged in the grip portion 2 and is close to the joint between the grip portion 2 and the folding portion 3, and the magnetic component is arranged at the position corresponding to the joint. In the unfolded state of the handheld accessory body 1, the Hall element and the magnetic component are relatively far away from each other, and a magnetic field induced by the Hall element is weak. When the handheld accessory body 1 is in the folded state, the Hall element is close to the magnetic component, and a magnetic field induced by the Hall element becomes stronger. The Hall element converts an induced magnetic field change into an electrical signal and transmits the electrical signal to the control module 15. The control module 15 determines a state of the handheld accessory body 1 according to different electrical signals and correspondingly adjusts a speed of the motor fan assembly 4. Specifically, through the cooperation between the Hall element and the magnetic component, the speed of the motor fan assembly 4 can be automatically adjusted according to the different states of the handheld accessory body 1, thereby achieving intelligent adjustment on a wind speed: In the unfolded state, the handheld accessory is suitable for a higher wind speed to meet specific needs. In the folded state, the wind speed is reduced, which can avoid unnecessary strong wind interference and be more energy-efficient. For example, in the unfolded state, the air outlet pressure is 150; and in the folded state, the air outlet pressure is 120.
In an embodiment of the present disclosure, a mounting slot 17 is provided in a surface of the folding portion 3 located at the first air inlet 6 in a recessed manner; the mounting slot 17 is connected with an air inlet mesh 18; clamping holes 19 are provided in two sides of the mounting slot 17 in a recessed manner; and clamping convex blocks 20 matched with the clamping holes 19 are arranged on two sides of the air inlet mesh 18 in a protruding manner.
Dustproof nets 21 are arranged at the mounting slot 17 of the folding portion 3.
By the arrangement of the air inlet mesh 18 and the dustproof nets 21, it is beneficial for daily dust prevention and safety protection. The air inlet mesh 18 can be mounted on the mounting slot 17 through the plugging fit between the clamping convex blocks 20 on the two sides of the air inlet mesh 18 and the clamping holes 19, which facilitates the production and machining of the air inlet mesh 18. This mounting mode is also convenient for the removal of the air inlet mesh 18. Especially when the handheld accessory body 1 is in the folded state, the air inlet mesh 18 can be appropriately removed, which is conducive to increasing the air inlet volume.
Referring to FIG. 7 , the present disclosure further provides a warm-air comb, applying the above handheld accessory with good air inlet performance, including a hand shank and an air comb head 22. The handheld accessory body 1 corresponds to the hand shank, and the air comb head 22 is detachably connected to one end of the folding portion 3 away from the grip portion 2.
The handheld accessory body 1 is a hand shank portion corresponding to the warm-air comb, and the detachable connection relationship between the handheld accessory body 1 and the air comb head 22 is not limited to magnetic suction, clamping, rotatable clamping, and other ways known to those of ordinary skill in the art.
For those skilled in the art, it is apparent that the present disclosure is not limited to the details of the exemplary embodiments mentioned above, and can be implemented in other specific forms without departing from the spirit or basic features of the present disclosure. Therefore, in any perspective, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present disclosure is limited by the accompanying claims rather than the above description. Therefore, all changes within the meaning and scope of the equivalent conditions of the claims within the present disclosure.
