Description

Technical Field

[0001] This utility model relates to the field of fans, and in particular to a handheld fan. Background Technology

[0002] Currently, handheld fans are widely popular due to their small size and suitability for carrying outdoors. Among existing handheld fans, a patent application (patent number 202222271169.3) entitled "An Outdoor Neck Hanging Fan" is disclosed in Chinese patent literature. This solution mainly includes a handheld fan body consisting of a vertically arranged handle and a fan body, a hanging rope, and two elastic cords. The fan body and handle are rotatably connected via a rotating connector and a locking mechanism. The two ends of the hanging rope and one end of each elastic cord are connected to the left and right sides of the handle, respectively. When used handheld, the fan body is rotated so that its airflow direction is perpendicular to the central axis of the handle. When used as a neck hanger, the hanging rope is first hung around the neck, then the other ends of the two elastic cords are wrapped around the back and connected. Finally, the fan body is rotated so that its airflow direction is upward and parallel to the central axis of the vertical handle. Although this solution can be used both handheld and around the neck, it still has the following shortcomings in practical applications:

[0003] First, when the fan is worn around the neck, the handle remains vertical, and only the handle contacts the body. This means that during walking, the fan body is prone to rotating and swinging around the handle, causing the fan to not deliver air precisely and affecting the comfort of the breeze. Although tightening the two elastic cords can help prevent rotation and swinging to some extent, it creates a strong constricting feeling, which is very uncomfortable, and tightening the two elastic cords is also very inconvenient.

[0004] Secondly, switching between handheld and neckband modes requires rotating the fan body, increasing the number of actions involved and making it less convenient.

[0005] Third, the design incorporates an elastic rope component, as well as rotating connectors and locking mechanisms, which not only makes the overall structure very complex, increases the difficulty of design and development, and raises manufacturing costs, but also increases the overall size, leading to increased packaging costs. These manufacturing and packaging costs will be passed on to the product price, resulting in a high price for the neck fan and a lack of market competitiveness.

[0006] Therefore, given the aforementioned shortcomings and deficiencies of existing neck fans, it is essential to redesign and improve their structure in order to better meet people's actual usage needs. Utility Model Content

[0007] The purpose of this invention is to solve the above-mentioned problems and shortcomings by providing a handheld fan with a neck-hanging function. When used with the neck hanging function, the handheld fan body is arranged in a horizontal position, allowing both the main body of the fan and the vertical handle to rest against and contact the human body. This prevents the main body of the fan from rotating or swaying, ensuring precise air delivery and comfortable blowing. Furthermore, it eliminates the need for elastic cord components, rotating connectors, and locking mechanisms, while still achieving state switching and preventing tilting or swaying. The structure is simpler, significantly reducing manufacturing costs and overall size, thus reducing packaging volume and material costs. This makes the handheld fan more affordable and enhances its market competitiveness.

[0008] The technical solution of this utility model is implemented as follows: A handheld fan with a neck-hanging function includes a hanging rope and a handheld fan body composed of a fan body and a vertical handle. The air outlet direction of the fan body is perpendicular to the central axis of the vertical handle. The vertical handle contains a power source electrically connected to the fan body. The key feature is that the upper end of the fan body and the lower end of the vertical handle are respectively provided with hooks, and both hooks are located at the front end of the handheld fan body. The two ends of the hanging rope are respectively connected to the two hooks. When the hanging rope is hung around a person's neck, the handheld fan body is arranged in a horizontal position, and the air outlet direction of the fan body is upward.

[0009] Preferably, the hook portion of the vertical handle is located at the lower end of the front side of the vertical handle.

[0010] Preferably, the fan body and the vertical handle are an integral structure.

[0011] Preferably, the fan body includes a cylindrical fan housing that runs through the front and rear, a motor disposed in the cylindrical fan housing, fan blades fixed to the power output end of the motor, and a front cover placed on the front end of the cylindrical fan housing. The rear end of the cylindrical fan housing and the front cover are respectively provided with grid mesh. The cylindrical fan housing and the vertical handle are integral structures. The motor is electrically connected to the power supply. The hook part of the fan body is disposed on the top of the front cover.

[0012] Preferably, the cylindrical fan housing is further provided with a speed-increasing cylinder that runs through the front and back. The speed-increasing cylinder is provided with a fixed support, and a number of airflow pressurizing plates arranged around the fixed support are provided between the fixed support and the speed-increasing cylinder. The motor and the fan blade are respectively disposed in the speed-increasing cylinder, and the motor is fixed on the fixed support.

[0013] Preferably, the speed-increasing cylinder and the cylindrical fan housing are further provided with a fastening protrusion and a fastening groove that are fastened together.

[0014] Preferably, the present invention further includes an ice pack assembly disposed in the middle of the front cover; the ice pack assembly includes a cooling plate disposed in the middle of the grid, a heat dissipation aluminum plate disposed behind the cooling plate, and an ice pack metal plate disposed at the front end of the cooling plate; the cooling plate is electrically connected to a power source.

[0015] Preferably, the vertical handle includes a handle housing with a front opening, a control circuit board disposed in the handle housing, a switch control button disposed on and electrically connected to the control circuit board, and a cover plate covering the opening. The cover plate has a through hole for the switch control button to pass through. The power supply is disposed in the handle housing, and the control circuit board is electrically connected to the power supply. The handle housing and the fan body are an integral structure, and the hook part of the vertical handle is disposed at the lower end of the front side of the cover plate.

[0016] Preferably, the control circuit board is further provided with a charging interface that is electrically connected to the power supply, and the outer surface of the handle housing or cover is further provided with a clearance through hole that is connected to and communicates with the charging interface.

[0017] Preferably, a lens is also provided on the side of the handle housing; and an anti-slip pad is also provided on the bottom surface of the handle housing.

[0018] The beneficial effects of this utility model are:

[0019] This invention provides hooks at the upper end of the fan body and the lower end of the vertical handle for connecting the two ends of the hanging rope. When used around the neck, the handheld fan body is laid horizontally, allowing both the fan body and the vertical handle to rest against and contact the human body. This prevents the fan body from rotating or swinging, ensuring precise air delivery and a comfortable blowing experience.

[0020] Furthermore, by placing both hooks at the front of the handheld fan body, the center of gravity of both the fan body and the vertical handle is downward when the fan is hanging around the neck. This prevents the handheld fan body from tilting or flipping, ensuring that the airflow direction of the fan body remains upward, further guaranteeing precise air delivery and comfortable blowing.

[0021] Meanwhile, by setting the air outlet direction of the fan body to be perpendicular to the central axis of the vertical handle, the air blown by the fan body can blow towards the person in the vertical holding state, and can also maintain upward airflow in the neck hanging state. Therefore, there is no need to rotate the fan body when switching between handheld and neck hanging states, making the switching operation simpler.

[0022] At the same time, compared with existing neck fans, it eliminates the need for elastic cord components, rotating connectors, and locking mechanisms, while still achieving state switching and preventing pitching and swaying. This simplifies the structure, greatly reduces design and development difficulty, significantly lowers manufacturing costs, and allows for a smaller overall size, thus reducing packaging volume and material costs. This makes the handheld fan more affordable and enhances its market competitiveness. Attached Figure Description

[0030] like Figure 1 and Figure 4 As shown, the present invention discloses a handheld fan with a neck-hanging function, comprising a hanging rope 2 and a handheld fan body 1 consisting of a fan body 11 and a vertical handle 12. The air outlet direction of the fan body 11 is perpendicular to the central axis direction of the vertical handle 12. The vertical handle 12 is provided with a power supply 3 electrically connected to the fan body 11. To achieve the purpose proposed by the present invention, such as... Figure 1 and Figure 3 As shown, the upper end of the fan body 11 and the lower end of the vertical handle 12 are respectively provided with hook parts 10, and both hook parts 10 are located at the front end of the handheld fan body 1; the two ends of the hanging rope 2 are respectively connected to the two hook parts 10; when the hanging rope 2 is hung on the neck of a person, the handheld fan body 1 is arranged in a horizontal position, and the air outlet direction of the fan body 11 is arranged upward.

[0031] In order to ensure that the hook part 10 does not affect the flatness of the bottom surface of the vertical handle part 12, so that the handheld fan body 1 can be placed on the table in an upright state for use, the hook part 10 of the vertical handle part 12 is located at the lower end of the front side of the vertical handle part 12.

[0032] In practical applications, the fan body 11 of this invention can be hinged to the top of the vertical handle 12 via a hinge shaft (not shown), allowing the tilt angle of the fan body 11's airflow direction to be adjusted when the fan body 1 is placed on a table for use, while also ensuring the accuracy of airflow and making it more convenient to use. Preferably, as... Figure 3 and Figure 4 As shown, the fan body 11 and the vertical handle 12 of this invention are integrated into one structure. This eliminates the need for a hinge structure, making the overall structure of the handheld fan body 1 simpler and easier to manufacture.

[0033] To further improve the structure of the fan body 11, making it simpler, more scientifically sound, and easier to manufacture, such as... Figure 3 As shown, the fan body 11 includes a cylindrical fan housing 111 extending from front to back, a motor 112 disposed within the cylindrical fan housing 111, fan blades 113 fixed to the power output end of the motor 112, and a front cover 114 covering the front end of the cylindrical fan housing 111. The rear end of the cylindrical fan housing 111 and the front cover 114 are respectively provided with grilles 115. The cylindrical fan housing 111 and the vertical handle 12 are integrally formed. The motor 112 is electrically connected to the power supply 3. The hook portion 10 of the fan body 11 is located on the top of the front cover 114. This structural design facilitates both manufacturing and rapid assembly. By providing grilles 115 on the rear end of the cylindrical fan housing 111 and the front cover 114, during airflow, it prevents fingers from entering the cylindrical fan housing 111 and avoids contact between fingers and fan blades 113, thus improving safety during use.

[0034] In order to increase the airflow speed from the main body 11 of the fan without increasing the power consumption of the motor, such as Figure 3 and Figure 6As shown, the cylindrical fan housing 111 also includes a speed-increasing cylinder 116 extending from front to back. A fixed bracket 117 is located within the speed-increasing cylinder 116, and several airflow pressure plates 118 arranged around the fixed bracket 117 are also provided between the fixed bracket 117 and the speed-increasing cylinder 116. The motor 112 and fan blade 113 are respectively located within the speed-increasing cylinder 116, and the motor 112 is fixed to the fixed bracket 117. By providing the airflow pressure plates 118, the area through which the airflow passes through the speed-increasing cylinder 116 is reduced, thereby pressurizing and accelerating the airflow. This allows the blown wind to travel further. When used handheld, there is no need to raise the handheld fan body 1 too high or bring it too close to the face, making it more comfortable to hold. Furthermore, when used around the neck, the length of the hanging strap 2 can be increased for easier wearing.

[0035] To ensure a more secure assembly between the speed-increasing cylinder 116 and the cylindrical fan housing 111, preventing them from easily coming loose, such as... Figure 3 , Figure 4 and Figure 6 As shown, a fastening protrusion 119 and a fastening groove 110 are provided between the speed-increasing cylinder 116 and the cylindrical fan housing 111 for interlocking connection. In practical applications, the fastening protrusion 119 is provided on the cylindrical fan housing 111, and the fastening groove 110 is provided on the speed-increasing cylinder 116. Of course, the positions of the fastening protrusion 119 and the fastening groove 110 can also be interchanged, achieving the same purpose of interlocking together.

[0036] To enhance the functionality of the handheld fan unit 1, such as... Figure 3 and Figure 5 As shown, this utility model also includes an ice pack assembly 4 disposed in the middle of the front cover 114; the ice pack assembly 4 includes a cooling plate 41 disposed in the middle of the grille 115, a heat dissipation aluminum plate 42 disposed behind the cooling plate 41, and an ice pack metal plate 43 disposed at the front end of the cooling plate 41; the cooling plate 41 is electrically connected to the power supply 3. By setting the heat dissipation aluminum plate 42, heat inside the cylindrical fan housing 111 can be dissipated, and the surrounding temperature of the motor 112 and fan blades 113 can be absorbed and cooled to maintain a suitable air outlet temperature. By setting the ice pack metal plate 43, heat can be conducted with the cooling plate 41, allowing the ice pack metal plate 43 to be in close contact with human skin, making the skin feel cooler and cooling faster. By adding the ice pack assembly 4, the cooling sensation of the blowing air can be improved. In practical applications, the cooling element 41 adopts a semiconductor cooling component currently used in handheld fans. Its specific structure and operating principle can be found in Chinese patent documents with authorization announcement numbers CN222334048U and CN217055650U, and will not be elaborated upon here. In practical applications, both the front cover 114 and the heat sink 42 are locked to the fixing bracket 117 with screws.

[0037] To further improve the structure of the vertical handle section 12, making it simpler, more scientifically sound, and easier to manufacture, such as... Figure 4 As shown, the vertical handle 12 includes a handle housing 122 with a front opening 121, a control circuit board 123 disposed in the handle housing 122, a switch control button 124 disposed on and electrically connected to the control circuit board 123, and a cover plate 125 covering the opening 121. The cover plate 125 has a through hole 126 for the switch control button 124 to pass through. The power supply 3 is disposed in the handle housing 122, and the control circuit board 123 is electrically connected to the power supply 3. The handle housing 122 and the fan body 11 are integrally formed. The hook part 10 of the vertical handle 12 is disposed at the lower end of the front side of the cover plate 125. This structural design facilitates both manufacturing and rapid assembly. By placing the hook part 10 on the cover plate 125, it is convenient to produce hook parts 10 of different styles without changing the structure of the handle housing 122, which is very beneficial to manufacturing. Specifically, the handle housing 122 and the cylindrical fan housing 111 are integrally formed.

[0038] To facilitate charging of power supply 3, such as Figure 4 and Figure 7 As shown, the control circuit board 123 is also provided with a charging interface 5 electrically connected to the power supply 3, and the outer surface of the handle housing 122 or the cover plate 125 is also provided with a clearance through hole 127 that communicates with the charging interface 5. In practical applications, preferably, the clearance through hole 127 is provided on the cover plate 125. This facilitates the production of clearance through holes 127 of different styles that match the charging interface 5 without changing the structure of the handle housing 122, which is very beneficial for manufacturing. Specifically, the clearance through hole 127 is located on the bottom surface of the cover plate 125.

[0039] To enhance the functionality of the handheld fan unit 1, such as... Figure 7 As shown, a lens 6 is also provided on the side of the handle housing 122. This makes it convenient for people to tidy their appearance at any time.

[0040] To ensure the handheld fan body 1 is more stable and less prone to slipping when placed on a table, such as... Figure 7 As shown, the bottom surface of the handle housing 122 is also provided with an anti-slip pad 7.

[0041] In practical applications, such as Figure 2 As shown, key rings 8 are provided at both ends of the lanyard 2. This allows the two ends of the lanyard 2 to be more securely, reliably, and detachably connected to the two hook parts 10, thus eliminating the need for frequent knotting of the lanyard 2, making it less prone to loosening, and more convenient to use.
