Description

Technical Field

[0001] This utility model belongs to the technical field of personal portable heat dissipation devices, and in particular relates to an adjustable neck fan. Background Technology

[0002] Neck fans have become a common personal cooling device for outdoor activities or high-temperature environments due to their advantages of freeing up hands and being easy to carry. Existing neck fans typically use a curved main body set at the back of the neck, with air-blowing arms extending from both ends. The fans blow air directly onto the body, using the principle of heat absorption through sweat evaporation to cool down.

[0003] To accommodate the different neck and shoulder contours of users, the connection part of a neck fan needs to be adjustable. Current technologies often use simple soft rubber connecting tubes, but their support and shaping capabilities are poor. Some products have attempted to introduce flexible metal hoses to improve adjustability and shaping capabilities; however, the simple plug-in or screw fixing between the metal hose and the plastic shell is prone to loosening and detachment during long-term, multi-angle use due to the stress and torque transmitted by the metal hose, seriously affecting the product's reliability and lifespan. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an adjustable neck fan to meet the needs of users.

[0005] To achieve the above objectives, this utility model provides an adjustable neck fan, including a neck support and air delivery mechanisms disposed at both ends of the neck support. The neck support and the air delivery mechanisms are connected by an adjustable connecting assembly. The adjustable connecting assembly includes a bendable connecting tube and a covering sleeve fitted over the connecting tube. One end of the connecting tube is fixedly connected to the neck support via a fastening connector, and / or the other end of the connecting tube is fixedly connected to the air delivery mechanism via a fastening connector.

[0006] The fastening connector includes a clamping ring for clamping and fixing the end of the connecting pipe and a connecting part connected to the clamping ring, the connecting part having an attachment section and a load section;

[0007] At least one of the neck support and the air supply mechanism includes a constraint gap into which the load section can be inserted. The load section is inserted into the constraint gap to achieve pre-positioning during installation. The attachment section is fixedly connected to the neck support and / or the air supply mechanism by fasteners.

[0008] Preferably, the constraint gap is formed by the space between the mounting post and the limiting part, the limiting part is disposed opposite to the mounting post, the load section is configured to bear the tensile force transmitted by the connecting pipe within the constraint gap, and the attachment section is fixed to the mounting post by fasteners.

[0009] Preferably, the attachment section is arranged perpendicular to the axis of the mounting post, and the load section is arranged parallel to the axis of the mounting post.

[0010] Preferably, the limiting part is configured as a partition, which is adapted to divide the internal space of the housing into a first chamber for accommodating the functional components and a second chamber for accommodating the end of the connecting pipe and the fastening connector.

[0011] Preferably, the constraint gap is formed by the space between several parallel mounting posts, and the attachment section is fixed to the mounting posts by fasteners.

[0012] Preferably, the load segment is configured to be inserted into the constraint gap in a direction parallel to the axis of the mounting column, or the load segment is configured to be inserted into the constraint gap in the radial direction of the connecting pipe.

[0013] Preferably, the attachment section is arranged along the tangential direction of the end of the connecting pipe, and the load section is arranged along the radial direction of the end of the connecting pipe.

[0014] Preferably, the connecting tube is a flexible metal tube, and the covering sleeve is a soft silicone sleeve. Both ends of the sleeve are inserted into the neck support and the air delivery mechanism, respectively. The wall of the covering sleeve has several annular stripes, which are evenly spaced along the extending direction of the covering sleeve. The covering sleeve outside the connecting tube serves two purposes: firstly, it isolates the flexible metal tube from direct contact with the skin, avoiding the risk of cold stimulation or allergies when sweating; secondly, the use of silicone material improves the wearing experience; and thirdly, it protects the connecting tube from impact and friction damage, extending its service life.

[0015] Preferably, the neck support includes an arc-shaped main shell, the inner surface of which is provided with a cooling pad for contacting the human body, and the interior of the arc-shaped main shell is provided with a semiconductor cooling assembly for cooling the cooling pad.

[0016] Preferably, the air supply mechanism includes a housing, a guide fan disposed within the housing, a battery, and a control circuit board.

[0017] The beneficial effects of this utility model are:

[0018] By incorporating adjustable connecting components, the air delivery mechanism can be adapted to the user's neck size and posture, solving the problem of traditional fixed structures failing to accurately target cold air to the desired area and improving the effectiveness of cooling. Users can freely bend the connecting tube to shape it according to their needs and adjust the angle of the air delivery mechanism. Once adjusted, the set angle can be maintained for a long time without the need for repeated calibration.

[0019] A strong fixed structure is established between the connecting pipe and the neck support / air supply mechanism by fastening the connectors. The clamp can tightly clamp the end of the connecting pipe to prevent relative sliding between the connecting pipe and the connecting part. After the load section is inserted into the constraint gap, it can directly bear the tensile force transmitted by the connecting pipe, such as the weight of the air supply mechanism and the adjustment external force. The axial tensile force transmitted by the connecting pipe is effectively distributed to the internal structure of the shell, avoiding loosening or falling off of the connection point due to stress concentration. Together with the attachment section, it is fixed by fasteners to form a triple fixed structure, which significantly improves the connection strength and greatly enhances the reliability and service life of the product.

[0020] By setting the load section insertion constraint gap, the relative positioning of the connecting pipe and the neck support / air supply mechanism can be quickly achieved during assembly, without the need for repeated position calibration. The attachment section is responsible for the final fixation with the neck support / air supply mechanism, and a single person can complete the installation of subsequent fasteners (such as screws), which greatly improves production assembly efficiency.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0032] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] like Figures 1 to 8As shown, an adjustable neck fan mainly includes a neck support 1, an air delivery mechanism 2, and an adjustable connecting assembly 3 connecting the two. The neck support 1 includes an arc-shaped main shell 11, with a metal cooling plate 12 embedded in its inner wall. A cooling assembly is provided inside the arc-shaped main shell 11, which includes a semiconductor cooling chip 13, a heat sink 14 that is in close contact with the hot end of the semiconductor cooling chip 13, and a cooling fan 15 mounted on the heat sink 14. The cooling plate 12 is in direct contact with the cold end of the semiconductor cooling chip 13 to efficiently transfer the cooling energy to the user's neck skin. The air delivery mechanism 2 includes a housing 21, inside which is a guide fan 22, a battery 23 that powers the entire device, and a control circuit board 24 that integrates a control unit. An air inlet 25 and an air outlet 26 are provided on the surface of the housing 21. When the guide fan 22 is running, the airflow is drawn in from the air inlet 25, accelerated through the drainage channel 27, and then blown towards the user's face or neck from the air outlet 26. The adjustable connection assembly 3 includes a connecting tube 31 and a covering sleeve 32 covering the connecting tube 31. The connecting tube 31 is a flexible metal tube. The covering sleeve 32 is a soft silicone shell made of flexible silicone material. The sidewall of the covering sleeve 32 is designed with annular stripes 321. The annular stripes 321 are completely closed along the circumference of the covering sleeve 32, forming an annular structure around the outer circumference of the covering sleeve 32. The annular stripes 321 are evenly distributed at the same interval along the extension direction of the covering sleeve 32, which can enhance the segmented shaping ability of the covering sleeve 32. This works in conjunction with the bendable shaping characteristics of the connecting tube 31 to further improve the stability of the connecting tube after bending. The flexible metal tube provides the necessary support and bendable shaping ability, while the silicone sleeve provides a comfortable feel and plays a protective role.

[0034] In this embodiment, the two ends of the connecting pipe 31 are fixedly connected to the neck support 1 and the blower of the air supply mechanism 2 respectively by fastening connectors 33. The fastening connector 33 is integrally stamped and bent from a hoop 331 and a connecting part 332. The hoop 331 is tightly clamped to the end of the connecting pipe 31. The connecting part 332 includes an attachment section 3321 and a load section 3322 that are perpendicular to each other. The attachment section 3321 has a through hole, and the load section 3322 is a one-piece structure. One fastening connector 33 is suitable for connecting the neck support 1. The attachment section 3321 of the fastening connector 33 is arranged along the tangential direction of the end of the connecting pipe 31, and the load section 3322 of the fastening connector 33 is arranged radially along the end of the connecting pipe 31. A corresponding mounting structure is provided inside the housing 21 of the neck support 1, and a corresponding mounting structure is also provided inside the arc-shaped main housing 11 of the blower of the air supply mechanism 2. The mounting structure includes two mounting posts 34, a connecting plate 36 adapted to connect the outer surfaces of the two mounting posts 34, and a limiting part 35 parallel to and opposite to the connecting plate 36. The limiting part 35 is preferably a plate-like structure. A narrow constraint gap 37 is formed between the mounting posts 34, the connecting plate 36, and the limiting part 35. Furthermore, this limiting part 35 divides the housing 21 into a first chamber for accommodating core functional components such as the airflow fan 22 and the battery 23, and a second chamber for accommodating the end of the connecting pipe 31, the fastening connector 33, and the wiring. This limiting part 35 also divides the arc-shaped main housing 11 into a first chamber for accommodating the cooling assembly and a second chamber for accommodating the end of the connecting pipe 31, the fastening connector 33, and the wiring.

[0035] The assembly process is as follows: First, the load section 3322 of the fastening connector 33 is inserted into the constraint gap 37 along the axial direction of the mounting post 34. This action achieves the pre-positioning of the entire connecting assembly and completes the radial constraint. The load section 3322 is confined in the constraint gap 37, which can effectively resist the axial tensile force transmitted from the connecting pipe 31. Then, the attachment section 3321 of the fastening connector 33 is aligned with the end face of the mounting post 34, and a fastener, i.e., a screw, is passed through the through hole on the attachment section 3321 and locked into the threaded hole of the mounting post 34, thereby achieving the final secure fixation.

[0036] It should be noted that those skilled in the art will understand that the two fastening connectors 33 suitable for connecting the neck support 1 and the blower of the air supply mechanism 2 can adopt the same basic structure or be slightly adjusted as needed. However, as long as they include the basic connection concept of fixing the connecting pipe 31 by the hoop 331 and realizing the combination of insertion and locking by the connecting part 332 with the attachment section 3321 and the load section 3322, they fall within the protection scope of this utility model.

[0037] The parts or connection methods not specifically described in this utility model, such as circuit connections and control logic, are implemented using or can be referenced from existing technologies, and will not be elaborated here.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
