Abstract
Description
Technical Field
[0001] This utility model relates to the field of fan equipment technology, and in particular to a neck-hanging fan. Background Technology
[0002] A neck fan is a portable small fan worn around the neck. It generates airflow through a motor-driven blade or turbine to achieve localized cooling. Its design is similar to over-ear headphones, eliminating the need to hold the fan, thus freeing up your hands, and making it suitable for outdoor activities, commuting, and other similar scenarios.
[0003] While existing neck fans can provide cooling and airflow, they still have some problems. First, current neck fans with bending functions cannot achieve smooth airflow during use. Second, the bending hinge of current neck fans can trap hair and skin, posing a safety hazard. Third, the air inlet at the bottom of current neck fans can suck in hair, which is also unsafe. Therefore, a new type of neck fan is needed to solve these problems. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide a neck fan that aims to solve the problems mentioned in the background art.
[0005] This utility model embodiment is implemented as follows: a neck fan includes: a lower central cover and a higher central cover, the lower central cover having an upper air outlet, and the upper central cover and the lower central cover being fitted together; an inner cover, having two inner covers and hinged to both ends of the lower central cover, the lower inner cover having an air inlet on its lower side and a lower air outlet on its upper side; an upper air duct plate, installed at the air inlet of the inner cover, a drive fan mounted on the upper air duct plate, the upper air duct plate being used to guide the air generated by the drive fan to the upper air outlet of the lower central cover, a lower air duct plate being fitted on the upper air duct plate, the lower air duct plate being used to guide the air generated by the drive fan to the lower air outlet of the inner cover; an outer cover, fitted together with the inner cover, the outer cover having a display window, a decorative strip mounted on the lower side of the display window; and a sealing cover, installed at the hinge of the lower central cover and the inner cover, for sealing the hinge of the lower central cover and the inner cover.
[0006] Preferably, the air inlet of the inner cover is in the form of small and densely packed circular holes, which reduces the air volume of a single hole to avoid drawing in hair.
[0007] Preferably, the hinge joint between the lower middle cover and the inner cover is interconnected, which allows the upper air duct plate to introduce air into the upper air outlet.
[0008] Preferably, the lower central cover and the inner cover are hinged together using bolts and nuts, and the hinge joint between the lower central cover and the inner cover adopts a semi-circular tight-fitting connection.
[0009] The neck fan provided by this utility model features a structural design that allows airflow to flow upwards, ensuring that the airflow from the bottom reaches the top smoothly even when the fan is slightly adjusted and bent during use. The design of the connection and bending points allows for smooth rotation, eliminating the safety hazards of hair or skin being caught. The shaft connection uses a screw, and the addition of anti-drop adhesive to the bolts and nuts increases the structure's robustness and reliability. The bottom air inlet of the neck fan features a dense perforated structure, preventing hair from getting caught and tangling in the fan. Through this reasonable and user-friendly product structure design, the neck fan offers better performance, convenience, aesthetics, and strong practicality. Attached Figure Description

Detailed Implementation
[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and do not limit the present utility model.
[0013] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0014] Please see Figure 1 This utility model provides a neck fan, which includes:
[0015] The system comprises a lower central cover 1 and an upper central cover 2. The lower central cover 1 has an upper air outlet 3, and the upper central cover 2 and the lower central cover 1 are fitted together. There are two inner covers 4, which are hinged to both ends of the lower central cover 1. The lower side of the inner cover 4 has an air inlet 5, and the upper side of the inner cover 4 has a lower air outlet 6. An upper air duct plate 7 is installed at the air inlet of the inner cover 4, and a drive fan 8 is mounted on the upper air duct plate 7. The upper air duct plate 7 is used to guide the air generated by the drive fan 8 to the lower central cover 1. The upper air outlet 3 is provided, and the lower air duct plate 9 is installed on the upper air duct plate 7. The lower air duct plate 9 is used to guide the air generated by the driving fan 8 to the lower air outlet 6 opened on the inner cover 4. The outer cover 10 is installed in conjunction with the inner cover 4. The outer cover 10 is equipped with a display window 11, and a decorative strip 12 is provided on the lower side of the display window 11. The sealing cover 13 is installed at the hinge of the middle lower cover 1 and the inner cover 4 and is used to close the hinge of the middle lower cover 1 and the inner cover 4.
[0016] When using this neck fan, you can move the inner cover 4 to control its rotation on the lower cover 1 in the middle. After adjusting the inner cover 4 to a suitable angle, put the entire neck fan around your neck and turn on the drive fan 8. Air can then flow into the inner cover 4 through the air inlet. The upper air duct plate 7 and the lower air duct plate 9 can divide the airflow into two parts. One part of the airflow is guided by the upper air duct plate 7 to the upper air outlet 3 for discharge, and the other part of the airflow is guided by the lower air duct plate 9 to the lower air outlet 6 for discharge, thereby achieving the cooling effect of blowing air from both the upper and lower parts.
[0017] like Figure 1 As shown, in a preferred embodiment of the present invention, the air inlet of the inner cover 4 is in the form of small and dense circular holes, which is used to reduce the air volume of a single hole to avoid drawing in hair.
[0018] In this embodiment, the air inlet 5 on the inner cover 4 is made into a small and dense circular hole, which reduces the air volume of a single hole and thus avoids the risk of hair being sucked in.
[0019] like Figure 1 As shown, in a preferred embodiment of this utility model, the hinged joint of the lower middle cover 1 and the inner cover 4 is interconnected, which is used to allow the upper air duct plate 7 to introduce air into the upper air outlet 3.
[0020] In this embodiment, a duct connection structure is designed and fabricated at the hinge of the lower cover 1 and the inner cover 4, based on the principle of communicating vessels. Even with slight adjustments from a static 180-degree to a 150-degree bend, ventilation can still be achieved. The air supply duct is divided into two parts from the air outlet of the drive fan 8, ensuring that both the upper air outlet 3 and the lower air outlet 6 have sufficient air volume and smooth ventilation.
[0021] like Figure 1As shown, in a preferred embodiment of the present invention, the lower central cover 1 and the inner cover 4 are hinged together by bolts and nuts, and the hinge joint between the lower central cover 1 and the inner cover 4 adopts a semi-circular close-fitting connection.
[0022] In this embodiment, the hinge between the lower middle cover 1 and the inner cover 4 uses a bolt-fitting method. The bolt thread surface is reinforced with anti-loosening rubber (anti-loosening rubber) nut locking, and a rubber ring is added between the upper and lower structural fasteners to increase the coefficient of friction. Based on the weight of the product itself, it will not fall when lifted (the inner rubber ring increases the frictional resistance). The structure at the joint between the lower middle cover 1 and the inner cover 4 uses a semi-circular close-fitting form with the upper and lower parts separated, ensuring that there is no risk of hair or skin being pinched when the joint is bent inward during use.
[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
