The following is a detailed explanation of the embodiment of the hanging neck fan according to the present disclosure, combined with the accompanying drawings.

Compared with the embodiments shown in the accompanying drawings, feasible embodiments within the scope of the present disclosure may have fewer components, other components not shown in the drawings, different components, members arranged differently, or components connected differently. Furthermore, without departing from the concepts disclosed herein, two or more components in the drawings may be implemented in a single component, or the single component shown in the drawings may be implemented as multiple separate components.

Hanging neck fan is a portable fan worn around a person's neck. It is known that a hanging neck fan is provided with multiple fans on a hanging neck component in contact with the neck to blow air at multiple positions on a user's neck. However, this type of hanging neck fan requires complex inlet and outlet air ducts, which is costly. In addition, the temperature blown out by the hanging neck fan is the ambient temperature. In summer outdoor environments with high temperatures, the temperature of the airflow blown out by the hanging neck fan is also higher, which causes poor cooling effect.

In addition, in order to improve a cooling effect, it is known to provide a semiconductor cooling chip on the hanging neck component for cooling. However, the power of semiconductor cooling chip is relatively high, which leads to an increase in power consumption.

Elements filled with a heat absorbing medium, such as a phase change material, gel material or oil, can absorb heat by changing the properties of solid and liquid, or by their own high specific heat capacity. This heat absorbing element can be attached to the human body, thereby playing a role of cooling and refreshing.

In response to the shortcomings of existing technology, the present disclosure proposes a new type of hanging neck fan, which detachably connects the hanging neck component filled with a heat absorbing medium and the fan together, achieving good ventilation and cooling effects with a simple structure and low cost, and is energy-saving and environmentally friendly. The following will provide an exemplary description of embodiments of the hanging neck fan proposed in the present disclosure, with reference to the accompanying drawings.

FIGS. 1 to 6 illustrate a hanging neck fan according to at least one embodiment of the present disclosure. As shown in FIG. 1, the hanging neck fan includes a fan component 1, a hanging neck component 2, and at least one connection mechanism 3 connecting the fan component 1 and the hanging neck component 2. In the embodiments shown in FIGS. 1 and 2, two fan components 1 and corresponding two connection mechanisms 3 are shown. The number of fan component and connection mechanism may be more or less, and the present disclosure is not limited to this. The connection mechanism 3 can detachably connect the fan component 1 and hanging neck component 2 together.

The hanging neck component 2 is formed as a whole in a curved shape that fits a human's neck, which can be comfortably worn on the human's neck and fits on surface of the skin at the neck. The hanging neck component 2 is made of polymer materials, such as polyurethane (TPU) material, which is filled with a heat absorbing medium. The heat absorbing medium may be, for example, a phase change material, a gel material or oil.

Phase Change Material (PCM) refers to a substance that changes its shape with temperature and can provide latent heat. A process by which the phase change material changes from solid to liquid or from liquid to solid is called a phase change process. At this time, the phase change material will absorb or release a large amount of latent heat. Water is a most common phase change material, when the temperature drops to 0° C., water changes from liquid to solid (freezing). When the temperature is above 0° C., water changes from solid to liquid (melts). During a freezing process, a large amount of cold energy is absorbed and stored, while during a melting process, a large amount of thermal energy is absorbed. For this embodiment, in addition to water, in an implementation mode, the phase change material can be a solid-liquid phase change material, with a phase change temperature (or solidification point) around room temperature (16° C. to 33° C.), such as advanced fatty hydrocarbons (n-hexadecane, n-octadecane, paraffin, etc.), fatty acids and their esters (stearic acid, palmitic acid, etc.), crystalline hydrated salts (Na₂SO₄.10H₂O, Mn(NO₃)₂.6H₂O, etc.), molten salts (LiF, NaF, CaF₂, etc.), metals and alloys (lead tin alloys, etc.), and polymers (polyethylene glycol, etc.).

In an actual use, the hanging neck component 2 filled with a phase change material can be stored at a low temperature for a period of time, and then taken out. At this time, the phase change material is in a solid state. Then the hanging neck component 2 is connected to the fan component 1 through the connection mechanism 3, so that it can be hung at the human's neck for cooling and ventilation. Due to a detachable connection between the hanging neck component 2 and connection mechanism 3, when the temperature of the phase change material in the hanging neck component 2 approaches a room temperature and the cooling effect deteriorates, the hanging neck component 2 can be dissembled and replaced with a new hanging neck component 2 that has been stored at low temperature, thus, it is convenient to replace.

How to detachably connect the hanging neck component 2 to the connection mechanism 3 in a simple and cost-effective way is a technical problem that needs to be solved. Firstly, TPUs filled with the phase change material are difficult to form a separate connecting shell, and may require a separate external shell for connection to wrap around the TPU material, with additional elastic members providing compliance and flexibility, which causes complex structures and higher costs. And due to the TPU material is not directly adhering to the human skin, the cooling effect is also affected.

Therefore, the present disclosure provides a new connection way by proving with an installation hole at at least one end of the hanging neck component, which is connected to the connection mechanism through a hole-column connection way. This connection way is simple and cost-effective, without the need for additional shells or connectors on the hanging neck component.

In addition, the present disclosure further proposes a process method for manufacturing such hanging neck component, which can include the following steps:

- S1. Providing a TPU material with an opening at at least one end and being hollow;
- S2. Injecting a heat absorbing medium into the TPU material;
- S3. Pressing an opening end of the TPU material tightly and fusing into one with an ultrasonic welding;
- S4. Processing a through hole at a fused part.

It should be noted that the hanging neck component can also be connected to the connection mechanism with an adhesion agent or a glue instead of proving with the installation hole.

FIGS. 3 and 4 further exemplify show the structure of the installation hole 5 of the hanging neck component 2. As shown in FIG. 4, the installation hole 5 can be a step hole structure, which includes a first counter bore portion 51, a second counter bore portion 52, and a through-hole portion 53 between the first counter bore portion 51 and the second counter bore portion 52. A diameter of the through-hole portion 53 is smaller than that of the first counter bore portion 51 and second counter bore portion 52, and thereby forming a flange 54 between the through-hole portion 53 with the first counter bore portion 51 and/or the second counter bore portion 52. For example, the first counter bore portion 51 and second counter bore portion 52 may be symmetrically arranged relative to the through-hole portion 53.

Returning to the embodiments in FIGS. 1 to 6, the connection mechanism 3 includes a first portion 31 and a second portion 32 in an axial direction, which are respectively configured to connect the hanging neck component 2 and the fan component 1. The first portion 31 is detachably connected to the hanging neck component 2, the second portion 32 is detachably connected to the fan component 1.

As shown in a cross-sectional view of FIG. 6, the connection mechanism 3 is formed by enclosing two half shells, respectively referred to as a first shell 33 and a second shell 34. Each shell 33, 34 may include a cover and a main body provided with installation columns 61, 62, the cover and main body may be connected by a buckle, for example. In the embodiment shown in FIG. 6, the first installation column 61 abuts against one surface of the flange 54 of the installation hole 5, the second installation column 62 abuts against another surface opposite to that surface of the flange 54 of the installation hole 5.

FIG. 6 shows two optional embodiments of the installing column 6, respectively.

One side wall of the first installation column 61 of the first shell 33 has an arc-shaped surface that fits with the first counter bore portion 51 and/or the second counter bore portion 52 of the first end 21 or the second end 22 of the hanging neck component 2. One end of the first installation column 61 in contact with the flange 54 has a diameter roughly equal to a size of the flange 54, the other end opposite to said end is provided as an opening structure. The cover can close the opening structure.

One side wall of the second installation column 62 of the second shell 34 may also have an arc-shaped surface that fits with the first counter bore portion 51 and/or the second counter bore portion 52 of the first end 21 or the second end 22 of the hanging neck component 2, and an end of the second installation column 62 contacting with the flange 54 also has a diameter roughly equal to a size of the flange 54. The difference is that the second installation column 62 has a through-hole structure that is intercommunicated and is arranged coaxially with the second installation column 62, the through-hole structure accommodates a third installation column 63 provided on the cover that matches it. The third installation column 63 passes through the through-hole structure of the second installation column 62 and abuts against one surface of the flange 54 together with an end of the second installation column 62. In an implementation mode, the first installation column 61, the second installation column 62, the third installation column 63, and the through-hole portion 53 are coaxial with each other.

The installation column 6 of the above two structures can be used in combination or separately. In an implementation mode, when the installation columns 6 with two structures are used in combination, two mirror symmetrical connection mechanisms 3 can reuse the installation columns 6 with the two structures. The only difference is that the order of the two can be reversed. Correspondingly, the order of the first shell 33 and the second shell 34 can also be reversed, which can save mold manufacturing costs. All parts used for the two connection mechanisms 3 can be produced with one set of molds.

When installing the hanging neck component 2, first counter bore portion 51 of the first end 21 or the second end 22 of the hanging neck component 2 is firstly fit with the first installation column 61 of the first shell 33, then the second installation column 62 of the second shell 34 is fit with the second counter bore portion 52, the third installation column 63 of the cover of the second shell 34 is finally inserted into the through-hole structure of the second installation column 62, and the flange 54 is pressed tightly. On the contrary, when disassembling the hanging neck component 2, the cover of the second shell 34 and its third installation column 63 are first drawn from the through-hole structure of the second installation column 62, then the second installation column 62 is separated from the second counter bore portion 52, so as the first end 21 or the second end 22 of the hanging neck component 2 is separated from the first shell 33.

In an embodiment, the installation hole 5 can be configured as a through hole, the installation column 6 directly passes through the through hole and fits with an inner wall of the through hole.

In addition to the connection between the end of the hanging neck component and the connecting module, the present disclosure further proposes various connection ways for the fan component and the connecting module. The following will provide a detailed description in combination with the accompanying drawings. It should be noted that those skilled in the art may use one or more of the connection way disclosed in the present disclosure, or a combination thereof.

FIGS. 7 to 12 exemplify show the hanging neck fan according to at least one embodiment of the present disclosure, which show an optional connection way between the fan component and the connection mechanism.

As shown in FIGS. 10 to 12, the fan component 1 may include a fan body 11 and an installation portion 12 provided on one side of the fan body. The fan body 11 has a roughly cylindrical contour, on which an air inlet 13 and an air outlet 14 are provided. The air inlet 13 is provided on an opening of a top surface of the fan body 11 and can be surrounded by an upper cover 15 that partially covers the opening. There is a gap between the upper cover 15 and the opening of the top surface of the fan body 11, through which air can enter the fan body 11. The air outlet 14 is provided around a circumferential side wall of the fan body 11, in an implementation mode, the air outlet 14 faces the neck or face of the human. For example, the air outlet 14 includes multiple grooves that are parallel arranged along a circumferential sidewall and the grooves are intercommunicated.

As shown in FIG. 12, the fan body 11 is provided with a fan blade assembly 111 and a drive motor 112. The drive motor 112 is configured to drive the fan blade assembly 111 to rotate, thereby generating airflow and continuously outputting airflow to the human body. In order to facilitate the air outlet from one side wall of the fan body 11, the fan blade assembly 111 is non-concentric with the fan body 11, and in an implementation mode, it is to set a distance from an edge of the fan blade assembly 11 to an inner wall of the fan body 11 to be gradually spaced, a maximum distance is reached at the air outlet 14. For the sake of simplicity, the present disclosure omits other components of the fan component 1 that are less related to the concept of the present disclosure, such as battery, control circuit board, wire, and other common components of fan components. Those skilled in the art can adjust and provide them according to an actual need.

Referring to FIGS. 8 and 10, the installation portion 12 is provided with a connecting rod 7, which extends from a side wall of the fan body 11, an end of the connecting rod 7 is provided with a spherical connecting head 71. As shown in a cross-sectional view of FIG. 8, a screw hole can be provided at a bottom of the connecting rod 7, which is installed on the fan body 11 through a screw.

As shown in FIG. 7, a connecting portion 35 is provided at the second portion 32 of the connection mechanism 3. A side of the connecting portion 35 has an opening, a spherical cavity 8 is provided to accommodate the spherical connection head 71. A size of the spherical cavity 8 is basically matched with that of the spherical connection head 71. The spherical connection head 7 can enter the spherical cavity 8 from a side opening of the connecting portion 35 to allow the spherical connection head 7 to freely rotate along the surface of the spherical cavity 8, so that a spatial angle of the fan component 1 relative to the connection mechanism 3 can be flexibly adjusted to adjust an appropriate outlet angle for blowing towards the human body.

In order to fix the position of the spherical connecting head 71, the hanging neck fan further includes a locking structure 9, the spherical connecting head 71 and the spherical cavity 8 are locked or unlocked with each other through the locking structure 9. Specifically, during locking, the spherical connecting head 71 is fixed in the spherical cavity 8; when unlocked, the spherical connecting head 71 can rotate within or separate from the spherical cavity 8.

It should be noted that “the spherical connecting head 71 being fixed in the spherical cavity 8” can include two situations: one is that the spherical connecting head 71 is completely fixed in the spherical cavity 8, at this time, the spherical connecting head 71 cannot move or rotate relative to the spherical cavity 8; the other is that the spherical connecting head 71 cannot separate from the spherical cavity 8, but can rotate at a certain angle.

FIGS. 8 and 9 illustrate one embodiment of the locking structure 9. The connecting portion 35 is provided with a sliding groove 921 along an axial direction and a movable slider 922 in the sliding groove 921, the slider 922 can move between a locking position and an unlocking position. In this embodiment, the slider 922 is provided on an opening on one side of the connecting portion 35.

In the unlocking position, as shown in FIG. 8, the slider 922 is separated from the spherical connecting head 71 of the connecting rod 7, the spherical connecting head 71 can be separated from the spherical cavity 8. In other words, in the unlocking position, the spherical connecting head 71 can also be installed into the spherical cavity 8.

After installing the spherical connecting head 71 into the spherical cavity 8, it can be moved down a certain distance d along an axial direction (a direction of a arrow in FIG. 9). At this time, the slider 922 reaches a downward extreme position in the sliding groove (represented by a dashed line in FIG. 9), the locking structure 9 is in the locking position. In the locking position, the slider 922 is able to couple with the spherical connecting head 71 of the connecting rod 7 and hinder the spherical connecting head 71 to separate from the spherical cavity 8. Specifically, due to the limitation of the slider 922, the spherical connecting head 71 cannot be moved out of the opening on the side of the connecting portion 35.

FIGS. 13 to 16 exemplarily illustrate the hanging neck fan in yet one embodiment of the present disclosure. For the sake of simplicity, the following will mainly describe the differences between this embodiment and the aforementioned embodiments. The structure of the undescribed parts can refer to the aforementioned embodiments and will not be repeated here. This description manner is also applicable to all embodiments described below.

In this embodiment, the locking structure 9 includes an external thread 911 that partially surrounds the spherical cavity 8 and a nut 912 that fits with the external thread 911. The spherical connecting head 71 is accommodated within the spherical cavity 8 and can be engaged and locked with the external thread 911 through the nut 912. The external thread 911 has multiple grooves 913 distributed along a circumference, the multiple grooves 913 extend along the axial direction, which allows the external thread 911 to move radially by a certain amount. Therefore, during locking, the external thread 911 can tighten radially to fix the spherical connecting head 71 in the spherical cavity 8. The external thread 911 can be made of hard plastic with a certain elasticity, for example.

In an implementation mode, the groove 913 can also be formed by splicing two half grooves of a halves of the two shells 33 and 34, as shown in FIG. 15.

The fan component 1 can be connected to the connection mechanism 3 through the following steps. The nut 912 is firstly unscrewed from the external thread 911 and sleeved on the connecting rod 7. Then, the spherical connecting head 71 of the fan component 1 is extended into the spherical cavity 8. The nut 912 is finally tighten into the external thread 911 radially to secure the spherical connecting head 71 to be fixed in the spherical cavity 8. Conversely, the nut 912 is unscrewed from the external thread 911, the spherical connecting head 71 can be removed from the spherical cavity 8.

Furthermore, in this embodiment, a protrusion 64 may be provided at an end of the second installation column 62 of the second shell 34, a cross-section of the protrusion 64 may be a cross shape, hexagonal, or in a shape of character “ custom-character ”, for example. The protrusion 64 passes through the through-hole portion 53 of the installation hole 5 and fits with an inner wall of the through-hole portion 53, as shown in FIGS. 14 and 16.

FIGS. 17 to 19 exemplify show the hanging neck fan in yet one embodiment of the present disclosure. Unlike the previous embodiments, the locking structure 9 of this embodiment includes a magnet 931 provided in the spherical cavity 8.
