Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically a handheld radiator. Background Technology

[0002] With the increasing severity of global climate change and energy consumption issues, the concept of energy conservation and environmental protection has gained widespread acceptance. Against this backdrop, people are increasingly inclined to use localized cooling devices instead of traditional centralized air conditioning systems to reduce energy consumption and environmental impact. Especially in summer or tropical regions, ambient temperatures are often very high, directly leading to sweaty and overheated hands. In daily life, prolonged use of computer mice, keyboards, and other devices, particularly in professional fields such as e-sports games and design work, generates a significant amount of heat from frequent hand movements, further exacerbating hand discomfort.

[0003] In addition, some people are naturally prone to sweaty hands due to physiological reasons, which can be exacerbated in hot weather or stressful work environments. Excessive hand sweating not only affects dexterity and reduces operational precision, but can also lead to damage to electronic devices or operational errors, causing inconvenience to work and daily life. On the other hand, for people with hand injuries or after surgery, appropriate cold compresses are an important part of the recovery process, as they can help reduce swelling and pain and promote wound healing.

[0004] Although various cooling devices exist on the market, such as fans and air-conditioning gloves, these devices often have design limitations, such as being bulky, inconvenient to carry, and having many usage restrictions, failing to meet people's needs for portability and flexibility. Therefore, developing a compact, easy-to-use handheld cooler that can effectively reduce hand temperature is particularly important. Utility Model Content

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0034] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0035] Reference Figure 1-5 The handheld radiator in this implementation plan is described below.

[0036] like Figures 1 to 3 As shown, the radiator includes a housing 1 and a base plate 14. The housing 1 and the base plate 14 are interlocked and then secured with three M2X6 screws, forming an internal cavity. The housing 1 is curved with one side protruding. When held in hand, the palm is located on the protruding part.

[0037] Furthermore, a first air hole 3 is opened on the upper surface of the outer shell 1. The first air hole 3 is an air outlet and is set on the protruding part of the outer shell 1 so that the blown gas acts on the palm of the hand to achieve the purpose of cooling the hand.

[0038] like Figure 1 As shown, the first air hole 3 is mesh-like, which makes the airflow evenly dispersed. At the same time, the outer shell 1 has an air inlet, which includes a first air inlet 5 and a second air inlet 6 respectively opened at both ends of the surgical 1. When the fan 11 is working, the external air enters through the first air inlet 5 and the second air inlet 6 and flows out through the first air hole 3 to act on the hand.

[0039] Furthermore, it also includes a female connector 2, located at the end of the outer casing 1, which is secured by two M2X4 screws. The female connector 2 is a Type-C female connector, and an external Type-C data cable can be plugged into the female connector 2.

[0040] In this embodiment, a fan 11 is installed inside the cavity, located below the first air vent 3 and fixed to the base plate 14. When the fan 11 operates, it delivers airflow to the first air vent 3 to cool the handheld portion of the user. The female connector 2 is electrically connected to the fan 11, supplying power to the fan 11 via an external Type-C data cable plugged into it. Furthermore, a switch for controlling the fan 11's on / off state is provided on the side wall of the outer casing 1.

[0041] It also includes an air duct assembly, which is connected to the first air inlet 5 and the second air inlet 6, and the fan 11 is connected to the air duct assembly. Specifically, the air duct assembly guides the gas entering through the first air inlet 5 and the second air inlet 6, and delivers the airflow to the air intake end position at the bottom of the fan 11.

[0042] In this embodiment, the air duct assembly includes a fan base 12, a first air duct 9, and a second air duct 13. Specifically, the fan base 12 has a hollow cavity with a slot formed on top. The fan 11 is installed in the slot above the fan base 12 and fixed with four M3X10 screws. The air inlet of the fan 11 communicates with the hollow cavity. One end of the first air duct 9 and the second air duct 13 are connected to the second air inlet 6 and the first air inlet 5, respectively, and completely cover the second air inlet 6 and the first air inlet 5. The other end of the first air duct 9 and the second air duct 13 are connected to the fan base 12. When the fan 11 is working, it generates a suction negative pressure. External airflow enters the first air duct 9 and the second air duct 13 through the second air inlet 6 and the first air inlet 5, respectively, and then enters the hollow cavity inside the fan base 12, where it is output by the fan 11 to the first air hole 3.

[0043] It should be noted that the first air duct 9 and the second air duct 13 cover the second air inlet 6 and the first air inlet 5.

[0044] In addition, to control the entry of external air through the second air inlet 6 or the first air inlet 5, an electric air valve 10 is provided at the connection between the first air duct 9 and the second air duct 13 and the fan base 12. A switch for controlling the operation of the two electric air valves 10 is provided on the side wall of the housing 1. During use, the user can control the opening and closing of the electric air valves 10 on the first air duct 9 or the second air duct 13 through the switch to adjust the front or rear airflow of the radiator.

[0045] In a preferred embodiment, there are two second air inlets 6, located on both sides of the female head 2.

[0046] For example, when there are two second air inlets 6, the first air duct 9 connected to them includes a main pipe 93 communicating with the fan base 12 and a first branch pipe 91 and a second branch pipe 92 connected to the two second air inlets 6, with the first branch pipe 91 and the second branch pipe 92 respectively connected to the two second air inlets 6.

[0047] Furthermore, the first branch pipe 91 and the second branch pipe 92 are interconnected with the main pipe 93 in a "Y" shape, and a clearance space 94 is formed between the first branch pipe 91 and the second branch pipe 92 to accommodate the female connector 2. The connecting line between the female connector 2 and the fan 11 is led out from the clearance space 94.

[0048] Furthermore, in this embodiment, a guide cover 7 fixed to the outer casing 1 is provided at the bottom of the first air hole 3. The guide cover 7 is suspended above the fan 11 and forms a gap 8 between it and the fan 11. It should be noted that the diameter of the guide cover 7 is larger than the outer diameter of the fan 11.

[0049] Meanwhile, a second vent 4 is also provided on the upper surface of the outer shell 1, and the second vent 4 is positioned opposite to the first vent 3.

[0050] It should be noted that when the airflow from fan 11 is delivered to the first air vent 3 through guide cover 7, a negative pressure occurs within the receiving cavity due to the closed design of the first air duct 9 and the second air duct 13. At this time, external air enters the receiving cavity through the second air vent 4, then passes through the gap 8 into guide cover 7, and together with the airflow from fan 11, is output through the first air vent 3. When external air enters the second air vent 4, it can draw in heat from the finger area.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
