Description

Technical Field

[0001] This utility model relates to the field of electric fan technology, and in particular to a portable fan that can be used for ice packs. Background Technology

[0002] Handheld portable fans are a convenient tool for cooling off, but in summer, due to the high ambient temperature, the air blown by the fan is also dry and hot, resulting in a poor user experience. With the development of technology, people have incorporated condensation components into the fan, so that the air blown out is cool, and the fan can directly cool the user, which can improve the user experience.

[0003] While most handheld mini fans on the market have condenser units at the air outlet, in actual use, users need to get very close to the outlet to feel the cooling effect. Furthermore, the strong airflow from the high-speed fan blowing directly on the face can cause eye discomfort when using the cooling function. At normal usage distances, the cooling effect is not noticeable to the user. Utility Model Content

[0004] The main purpose of this invention is to provide a portable fan that can be used for icing, which aims to make the fan easy to use and increase the area that can be iced.

[0005] To achieve the above objectives, this utility model proposes a portable fan that can be used for ice application, including a head assembly with fan blades and a handle connected to the outer periphery of the head assembly. The head assembly has a through-hole cavity, one end of the head assembly has an air inlet end opposite to the air duct cavity, and the other end has an air outlet end. The fan blades are arranged in a direction perpendicular to the direction from the air inlet end to the air outlet end.

[0006] The sidewall of the air duct cavity is provided with a condensation component, and the outer wall of the head component forms a cooling contact surface with respect to the cold end surface of the condensation component.

[0007] In one embodiment of this application, an annular condensation assembly is provided on the inner peripheral wall of the air duct cavity. The condensation assembly circumferentially covers the inner wall of the air duct cavity and surrounds the fan blade.

[0008] In one embodiment of this application, at least one independent condensation component is provided on the inner peripheral wall of the air duct cavity, and the total projected area of ​​the condensation component on the inner wall of the air duct cavity accounts for less than half of the circumferential projected area.

[0009] In one embodiment of this application, a control unit is provided on the outer periphery of the handle, and the control unit is connected to a control panel located inside the handle and used to connect to the motor and condenser assembly of the fan blades;

[0010] The handle contains a battery.

[0011] In one embodiment of this application, the control unit is provided with a first control unit relative to the motor of the fan blade, and the control unit is provided with a second control unit relative to the condensation assembly;

[0012] The first and second control units are set up independently.

[0013] In one embodiment of this application, the end of the handle opposite to the head assembly is provided with a bracket.

[0014] In one embodiment of this application, the end of the handle away from the head assembly is provided with an anti-slip structure.

[0015] In one embodiment of this application, the end of the handle opposite to the head assembly is provided with a hanging ring.

[0016] By adopting the above technical solution, this utility model has the following advantages:

[0017] The fan described in this application is a portable handheld fan. Its main structure consists of a head assembly for mounting fan blades and a handle that is integrally connected to the head assembly for handheld use. An air duct cavity is provided inside the head assembly. The air duct cavity passes through the fan blades from one end of the air inlet and exits from the other end of the air outlet. Unlike most handheld fans on the market that can be used for cooling and blowing air, this application does not have a condenser assembly at the air outlet. The air outlet is almost unobstructed except for protection. Therefore, when the fan of this application operates at the same power as fans on the market, the airflow of this application's fan can be significantly improved, which can effectively save energy and provide users with a more comfortable experience.

[0018] This application features a condensation component on the side wall of the air duct cavity. The condensation component is a semiconductor condensation structure that is sealed to the side wall of the air duct cavity and located on one side of the fan blades. This maximizes the utilization of the fan's internal space. Furthermore, because the condensation components of commercially available handheld fans that can be used for cooling are installed at the air outlet, and the area of ​​the air outlet is limited, the size of the condensation component itself is also limited. In contrast, the condensation component in this application is an arc-shaped sheet structure that can be attached to the side wall of the fan. The condensation component itself can have a larger area. With this structure, the outer periphery of the head component is connected to the condensation component to form a cooling contact surface. When the user needs a cooling treatment, they can directly apply it to the cooling contact surface on the fan. This cooling contact surface has a large area, and when the user is applying a cooling treatment, especially to areas like glasses, there will be no airflow blowing directly onto the user's glasses, making the cooling treatment more comfortable and effectively improving the user experience.

[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] The following is in conjunction with the appendix Figures 1 to 2 The present invention will be further described below.

[0027] To achieve the above objectives, this utility model proposes a portable fan that can be used for ice application, including a head assembly 1 with fan blades 4 and a handle 5 connected to the outer periphery of the head assembly 1. The head assembly 1 is provided with an air duct cavity 11. One end of the head assembly 1 is provided with an air inlet end relative to the air duct cavity 11, and the other end is provided with an air outlet end. The fan blades 4 are arranged in a direction perpendicular to the air inlet end to the air outlet end.

[0028] The side wall of the air duct cavity 11 is provided with a condensation component 3, and the outer wall of the head component 1 forms a cooling contact surface 2 relative to the cold end surface of the condensation component 3.

[0029] The fan described in this application is a portable handheld fan. Its main structure consists of a head assembly 1 with fan blades 4 installed and a handle 5 that is integrally connected to the head assembly 1 for handheld use. An air duct cavity 11 is provided inside the head assembly 1. The air duct cavity 11 passes through the fan blades 4 from one end of the air inlet and exits from the other end of the air outlet. Unlike most handheld fans on the market that can be used for cooling and blowing air, this application does not have a condenser assembly 3 at the air outlet. The air outlet is almost unobstructed except for protection. Therefore, when the fan of this application operates at the same power as fans on the market, the airflow of the fan of this application can be significantly improved, which can effectively save energy and provide users with a more comfortable experience.

[0030] This application provides a condensation component 3 on the side wall of the air duct cavity 11. The condensation component 3 is a semiconductor condensation structure, which is sealed to the side wall of the air duct cavity 11 and located on one side of the fan blade 4. This maximizes the utilization of the fan's internal space. At the same time, because the condensation component 3 of commercially available handheld fans that can blow air for cooling is installed at the air outlet, and the area of ​​the air outlet is limited, the size of the condensation component 3 itself is also limited. However, in this application, the condensation component 3 is an arc-shaped sheet structure that can be attached to the side wall of the fan. The condensation component 3 itself can be made with a larger area. With this structure, the outer periphery of the head component 1 is connected to the condensation component 3 to form a cooling contact surface 2. When the user needs to cool, they can directly use it by contacting the cooling contact surface on the fan. The area of ​​this cooling contact surface is large, and when the user is cooling, especially when cooling glasses, there will be no air blowing directly on the user's glasses, making the cooling more comfortable and effectively improving the user experience.

[0031] In one embodiment of this application, an annular condensation component 3 is provided on the inner peripheral wall of the air duct cavity 11. The condensation component 3 circumferentially covers the inner wall of the air duct cavity 11 and surrounds the fan blade 4.

[0032] The inner circumferential wall of the air duct cavity 11 is provided with annular condensing components 3. The annular condensing components 3 implicitly have two structural states: continuous and semi-continuous. In these two structures, the condensing components 3 can be one or more assembled structures that cover the inner wall of the air duct cavity 11, so that the outer wall of the fan can become the cooling contact surface 2. This allows users to use the cooling contact surface 2 directly without having to determine its location when they need to apply ice, making it more convenient to use.

[0033] In one embodiment of this application, at least one independent condensation component 3 is provided on the inner peripheral wall of the air duct cavity 11, and the total projected area of ​​the condensation component 3 on the inner wall of the air duct cavity 11 accounts for less than half of the circumferential projected area.

[0034] Because when users need to apply ice, in most scenarios the contact area between the user and the outer wall of the fan is less than half of the contact area of ​​the outer wall of the fan, in this embodiment, only one independent condensation component 3 is provided in the air duct cavity 11, and the total projected area of ​​the condensation component 3 on the inner wall of the air duct cavity 11 is less than half of the circumferential projected area, which can effectively improve energy utilization efficiency and reduce energy loss.

[0035] In one embodiment of this application, a control unit 51 is provided on the outer periphery of the handle 5. The control unit 51 is connected to a control panel located inside the handle 5 and used to connect to the motor of the fan blade 4 and the condenser assembly 3. A battery is provided inside the handle 5.

[0036] The handle 5 is equipped with a control unit 51 for operating the fan's working status. The control unit 51 is connected to a control panel (usually a PCB board). Since the control panel is connected to the motor of the fan blade 4 and the condenser assembly 3, the user can directly control the fan power and the cooling of the condenser assembly 3 through the control unit 51.

[0037] The handle 5 integrates a battery, which can be 8000mAh, providing long-lasting power for the small fan and reverse charging for electronic devices such as mobile phones and cameras.

[0038] In one embodiment of this application, the control unit 51 is provided with a first control unit relative to the motor of the fan blade 4, and the control unit 51 is provided with a second control unit relative to the condenser assembly 3;

[0039] The first and second control units are set up independently.

[0040] The motor of the fan blade 4 and the condenser assembly 3 can be controlled independently. Therefore, the control unit 51 is equipped with a first control unit and a second control unit for each of them. The above structure makes the fan easy to use.

[0041] In one embodiment of this application, a bracket is provided at the end of the handle 5 away from the head assembly 1. The fan can be placed directly on a desktop, providing a better user experience.

[0042] In one embodiment of this application, the end of the handle 5 facing away from the head assembly 1 is provided with an anti-slip structure. Because the handle 5 is a column, providing an anti-slip structure at the bottom of the column also enables the fan to stand upright, improving the user experience of the fan.

[0043] In one embodiment of this application, a hanging ring 52 is provided at the end of the handle 5 away from the head assembly 1. The hanging ring 52 enables the fan to have more non-handheld and stable operating modes, making the fan more convenient to carry.
