DETAILED DESCRIPTION

It should be noted that, as long as there is no conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other. The preferred embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.
Embodiments of the present disclosure provide a neck fan 10000. The neck fan 10000 is configured to be hung on a neck of a human body, so that a user is able to carry the neck fan 1000, and the neck fan 1000 is able to blow wind to the human body especially the neck and face, anytime and anywhere. As shown in FIGS. 1-3 , the neck fan 1000 comprises a neck hanging body 10 for hanging on the neck of the human body and fan assemblies 20. First air channels 101 are defined inside the neck hanging body 10. Wind flows in the first air channels 101 to realize good ventilation effect. In addition, first air inlets 102 and first air outlets 103 are defined on the neck hanging body 10. The first air inlets 102 and the first air outlets 103 are communicated with the first air channels 101 to facilitate a circulation of external air.
In the embodiment, fan accommodating structures 104 are protruded from one the side, facing the human body, of the neck hanging body 10. Each of the fan assemblies 20 is at least partially installed in a corresponding fan accommodating structure 104. The fan assemblies 20 are configured to enable the external air to enter the first air channels 101 from the first air inlets 102 and blow out along the first air outlets 103.
Compared with the prior art, in the neck fan 1000 of the present disclosure, the fan accommodating structures 104 are protruded on the one side of the neck hanging body facing the human body, and the fan assemblies 20 are at least partially installed in the fan accommodating structures 104 to reduce spaces for accommodating the fan assemblies 20 in the neck hanging body, that is, to reduce a volume and a thickness of the neck hanging body 10, thereby realizing an ultra-thin setting of the neck hanging body 10 and reducing a weight of the neck fan 1000. Therefore, the neck fan 1000 is light and handy when the user wears it, thus greatly improving a user experience.
In order to enable those skilled in the art to better understand solutions of the present disclosure, technical solutions in the embodiments of the present disclosure are clearly and completely described below with reference to the accompanying drawings of FIGS. 1-19 .
Furthermore, as shown in FIGS. 3 and 4 , in order to accommodate and fix the fan assemblies 20, each of the fan accommodating structures 104 comprises a fan mounting seat 105. Each fan mounting seat 105 is connected with the neck hanging body 10 to define a fan accommodating cavity 106. Each fan accommodating cavity 106 is communicated with a corresponding first air channel. Each of the fan assemblies 20 is installed on a corresponding fan mounting seat 105 and accommodated in a corresponding fan accommodating cavity 106.
In the embodiment, each fan mounting seat 105 is integrally formed with the neck hanging body 10. It should be noted that through such arrangements, on the one hand, an assembly process of each fan mounting seat 105 and the neck hanging body 10 is reduced, a processing time is saved, and processing efficiency is improved. On the other hand, each fan mounting seat 105 is more firmly fixed on the neck hanging body 10, reducing the inconvenience and unsafety caused by shaking, allowing the user to use the neck fan 1000 with more peace of mind, and better satisfying the user's needs.
Furthermore, as shown in FIGS. 1, 2, and 4 , each of the fan accommodating structures 104 further comprises a cover plate 107 configured to attach to skin of the human body. Each cover plate 107 is detachably installed on one side, facing the human body, of a corresponding fan mounting seat 105 of the neck hanging body 10. Each cover plate 107, the corresponding fan mounting seat 105, and the neck hanging body 10 together form a partition space 108 facing a corresponding accommodating cavity 106.
It should be noted that each partition space 108 may be or may not be communicated with the corresponding fan accommodating cavity 106, which is not limited thereto, and may be determined by those skilled in the art according to actual situations.
It should also be noted that through arrangements of each partition space 108 and each cover plate 107, the fan assemblies 20 are completely isolated from the skin of the human body, so that the fan assemblies 20 do not cause any danger to the human body when operating and fully guarantee safety of the user.
Moreover, each partition space 108 also improves operating efficiency of a corresponding fan assembly 20. Specifically, a large amount of heat is generated inside the fan assemblies 20, if each fan accommodation cavity 106 directly contacts the neck hanging body 10, the heat is directly conducted to the neck of the human body, which not only brings discomfort to the user, but also affects operating efficiency of a corresponding fan assembly 20. Each partition space 108 effectively reduces heat conduction, ensuring that the corresponding fan assembly 20 does not conduct the heat to the human body during operation, and at the same time improving the working efficiency of the corresponding fan assembly 20. In addition, each partition space 108 also reduces a noise generated by the corresponding fan assembly 20 when the corresponding fan assembly 20 is working, which ensures the user experience.
In the embodiment, as shown in FIGS. 5, 7, and 9 , snapping structures 30 are disposed between each cover plate 107 and the neck hanging body 10. The snapping structures 30 comprise clamping protrusions 301 and clamping grooves 302 respectively matched with the clamping protrusions 301. The clamping protrusions 301 are disposed on one of the neck hanging body and each cover plate 107. The clamping grooves 302 are defined on the other one of the neck hanging body 10 and each cover plate 107. When each cover plate 107 is installed on the neck hanging body 10, the clamping protrusions 301 are respectively clamped in the clamping grooves 302.
It should be noted that by adopting the above technical solution, not only can each cover plate 107 be firmly fixed on the neck hanging body 10, but also the subsequent maintenance of the fan assemblies 20 is facilitated. That is, each cover plate 107 is allowed to be detached from the neck hanging body 10 by directly releasing connections of the snapping structures 30 while the corresponding fan assembly 20 is not damaged.
Furthermore, as shown in FIGS. 1, 2, and 5 , in order to increase an air intake volume of the neck fan 1000, the neck hanging body 10 defines second air inlets 109. Each partition space 108 is communicated with corresponding second air inlets 109. Through holes 110 are defined on each fan mounting seat 105. The through holes 110 of each fan mounting seat 105 are communicated with a corresponding first air channel 101. Under an action of the fan assemblies 20, the external air sequentially passes through the second air inlets 109, each partition space 108, and the through holes 110 to enter each of the first air channels 101.
It is understood that when the fan assemblies 20 are working, the external air is driven by the fan assemblies 20 to enter the first air channels 101 through the first air inlets 102. At the same time, the external air may also enter each partition space 108 through corresponding second air inlets 109, and the external air entering each partition space 108 then enters a corresponding first air channel 101 through corresponding through holes 110, thereby realizing multi-path air intake of the neck fan 1000 and increasing the air intake volume.
It should be noted that all the external air entering the first air channels 101 is blown out to the neck and face of the human body through the first air outlets 103, thereby realizing a cooling effect.
Furthermore, arrangements of each cover plate 107 and the second air inlets 109 has many choices to realize different functions of the neck fan 1000. As shown in FIGS. 5 and 7 a of FIG. 7 , each fan mounting seat 105 comprises an end surface 1051 opposite to a corresponding cover plate 107 and an outer peripheral surface 1052 disposed around the end surface 1051. The second air inlets 109 corresponding to each fan mounting seat 105 are defined on the outer peripheral surface 1052 of each fan mounting seat 105 and penetrate the end surface 1051 of each fan mounting seat 105. When each cover plate 107 is covered on the end surface 1051 of a corresponding fan mounting seat 105, the multi-path air intake of the neck fan 1000 is realized, the air intake volume is increased, and the safety is improved.
Alternatively, as shown in FIGS. 5 and 7 b of FIG. 7 , each fan mounting seat 105 comprises the end surface 1051 opposite to the corresponding cover plate 107 and the outer peripheral surface 1052 disposed around the end surface 1051. The second air inlets 109 corresponding to each fan mounting seat 105 are defined on the outer peripheral surface 1052 of each fan mounting seat 105 and penetrate the end surface 1051 of each fan mounting seat 105. Each cover plate 107 comprises protruding portions 1071, and each of the protruding portions 1071 is accommodated in a corresponding second air inlet 109 to block the corresponding second air inlet 109.
Compared with the first embodiment of each cover plate shown in 7 a, when the user uses each cover plate 107 of the second embodiment shown in 7 b to cover the end surface 1051 of the corresponding fan mounting seat 105, each of the protruding portions 1071 blocks the corresponding second air inlet 109, so that the external air is unable to enter each partition space 108, thereby reducing the amount of the air intake.
By implementing the above two embodiments of each cover plate 107, different types of cover plates 107 are made for the user to freely select and flexibly replace according to different needs for air intake. It can be seen that applicability of the neck fan 1000 is good.
In one embodiment, the neck fan 100 further comprises conductive structures 40 and a control assembly 50. Each of the conductive structures 40 comprises an electrode plate 401, a first contact 402, and a second contact 403. Each electrode plate 401 is disposed on a corresponding cover plate 107 and at least partially exposed outside the corresponding cover plate 107. Each first contact 402 is electrically connected with a corresponding electrode plate 401. The second contact 403 is disposed on a corresponding fan mounting seat 105. Each second contact 403 is configured to be electrically connected with the control assembly 50. When each cover plate 107 is installed on the corresponding fan mounting seat 105, each first contact 402 and a corresponding second contact 403 are electrically connected with transmit a pulse to the corresponding electrode plate 401.
Specifically, when wearing the-neck fan 1000, the neck is in contact with each electrode plate 401 exposed outside each cover plate 107. The control assembly 50 transmits low-frequency current to each electrode plate 401 through each second contact 403 and each first contact 402 to relieve various types of pain of the neck. Each second contact 403 and each first contact 402 are metal spring pieces. Each first contact 402 directly contacts the corresponding second contact 403, which facilitates each cover plate 107 of the first embodiment or the second embodiment to realize a pulse massage function, and allows the user to choose whether to perform pulse massage by replacing different types of cover plates 107.
Furthermore, as shown in FIG. 9 , the neck fan 100 further comprises heating assemblies 60. Each of the heating assemblies 60 is installed in a corresponding partition space 108 to provide a hot compress function to the user.
Specifically, each of the heating assemblies 60 is a semiconductor heating sheet, which is installed in the corresponding partition space 108 through thermal conductive gel. When the neck fan 1000 is worn, each semiconductor heating sheet transmits heat to each cover plate 107 through the thermal conductive gel, so as to realize the hot compress function to the neck by each cover plate 107. The thermal conductive gel is conducive to heat transfer and improves a hot compress effect.
Furthermore, as shown in DIFS. 2 and 3, to enable the user to adjust the fan assemblies, the neck fan 100 comprises the control assembly 50. The control assembly 50 is disposed inside the neck hanging body 10. The control assembly 50 is disposed adjacent to a corresponding first air channel 101. The fan assemblies 20 are respectively connected with the control assembly 50.
Specifically, mounting cavities 120 are defined in the neck hanging body 10, each of the mounting cavities 120 is located at a periphery of a corresponding first air channel 101, the control assembly 50 is installed in a corresponding mounting cavity 120, and the control assembly 50 is connected with the fan assemblies 20 through wires by an operator.
It is understood that when the neck fan 1000 is working, the user controls the fan assemblies 20 to work through the control assembly 50. Under driving of the fan assemblies 20, the external air enters the first air channels through the first air inlets 102 and the second air inlets 109, and the external air entering the first air channels 101 is blown out to the neck and the face of the human body through the first air outlets 103, thereby realizing the cooling effect.
Furthermore, as shown in FIGS. 3, 5, and 6 , the neck fan 100 further comprises wiring structures 70. Each of the wiring structures 70 is disposed on a corresponding fan mounting seat 105. The wires the control assembly 50 pass through the wiring structures 70 and are electrically connected with the fan assemblies 20. In this way, directions of the wires are limited and the wires are fixed, making a wiring orderly, preventing the wires from falling off, and thus solving a problem of messy wiring.
Furthermore, in order to increase the air volume output by the neck fan 1000, air baffles 111 are disposed on an inner wall of the neck hanging body 10. Each of the air baffles 111 surrounds a corresponding fan assembly 20 and extends in a direction of corresponding first air inlets 103. The air baffles 111 and the neck hanging body 10 together define the corresponding first air channel 101.
It is understood that when the fan assembly 20 is working, the fan assemblies 20 drive the air to flow in the first air channels and blow out the air along a radial direction of the fan assemblies 20. At the same time, the air sent out from one side of each of the fan assemblies 20 away from the first air outlets 103 and the air from two sides of each of the fan assemblies 20 are blocked by each of the air baffles 111, so that the air blown out to corresponding first air outlets 103 by each of the fan assemblies 20 transmits along the corresponding first air channel 101. Namely, most of the air in the first air channels 101 is blown out along the first air outlets. Therefore, loss of the air volume delivered by the fan assemblies 20 is reduced, and an effective output air volume is increased to increase the air volume output by the neck fan 1000, thereby realizing better air supply effect and meeting user needs.
In one embodiment, each of the wiring structures 70 comprises an inlet 701, an outlet 702, and a wire pressing piece 703. Each inlet 701 and a corresponding outlet 702 are disposed on a corresponding fan mounting seat 105. Each outlet 702 is disposed on one side of a corresponding inlet 701 away from a center of a corresponding fan accommodating cavity 106. Each outlet 702 extends toward a corresponding air baffle 111 and penetrates the corresponding air baffle 111. Each wire pressing piece 703 is disposed adjacent to a corresponding air baffle 111 and a corresponding outlet 702, each wire pressing piece 703 and the corresponding outlet 702 jointly define a wire leading space 704, and each wire leading space 704 is configured to guide the wires. By such arrangements, each of the fan assemblies 20 is installed in the corresponding fan accommodating cavity 106. The wires of each of the fan assemblies 20 pass through a corresponding inlet 701 to a corresponding partition space, and then pass through a corresponding outlet 702 to the mounting cavity 120, which prevents the wires from being scratched and broken by the fan assemblies, and ensures safety. Each outlet 702 extends toward the corresponding air baffle 111 and penetrates the corresponding air baffle 111 to increase a size of each outlet 702 to facilitate passage of the wires during assembly. Then, each wire pressing piece 703 cooperates with the corresponding outlet 702 to limit positions of the wires in the corresponding wire leading space 704, thereby reducing a difficulty of arranging the wires and making assembly efficient.
Specifically, each wire pressing piece 703 comprises a fixing portion 7031 and a profiling portion 7032. Each fixing portion 7031 is detachably connected with a corresponding air baffle 111. Each profiling portion 7032 is disposed on one side of a corresponding fixing portion 7031 close to a corresponding fan accommodating cavity 106. Each profiling portion 7032 comprises a first connecting section 7032 a and a second connecting section 7032 b. Each first connecting section 7032 a is configured to shield a corresponding outlet 702, each second connecting section 7032 b is configured to shield a notch defined by a corresponding air baffle 111.
