Description

Technical Field

[0001] This utility model belongs to the field of outdoor fan technology, and in particular relates to an outdoor fan. Background Technology

[0002] Existing portable outdoor fans are designed to provide users with localized, portable cooling. However, when outdoor workers use them, for example, handheld fans require one hand to hold continuously, affecting their ability to perform tasks such as recording and operating equipment. Or, for example, fans that hang around the neck are prone to colliding or snagging with surrounding objects when the user bends over or turns, which may not only damage the fan but also pose an accidental risk during work, thus interfering with use. Furthermore, the airflow of existing fans can only reach the user's skin exposed outside clothing, and the airflow cannot penetrate the fabric to achieve effective heat exchange with the skin, resulting in poor performance. Summary of the Invention

[0003] To address the shortcomings of existing technologies, an outdoor fan is provided.

[0004] This utility model is achieved using the following technical solution:

[0005] An outdoor fan includes a fan body with an air duct inside. A first clamping component and a second clamping component are provided on the outer side of the fan body. The first and second clamping components clamp and fix the fan body in a first and a second direction, respectively. The air duct is located between the first and second clamping components. When the first and second clamping components are clamped and fixed, the first and / or second clamping components can lift outer clothing away from inner clothing or the user's skin, so that the air duct is located between the user's skin and the clothing / underwear and outer garment. The outer surfaces of the fan body are rotatably connected; the first clamping assembly and / or the second clamping assembly are connected to the outer surfaces of the fan body via a rotating member with a rotation angle of 360 degrees; the rotating member includes a snap-fit ​​plate for engaging with the first clamping assembly and / or the second clamping assembly and a rotating shaft rotatably connected to the fan body; the first clamping assembly and / or the second clamping assembly are relatively open and close clamping parts, the clamping parts are pivotally connected and divided into a power part and a resistance part by the pivot, and a torsion spring is wound between the clamping parts; a slot for matching the snap-fit ​​plate is provided on the back side of the clamping part.

[0006] When a user needs to cool down, the first and second clamping components are fixed to the outer and inner clothing, or the clothing and belt, respectively. This allows the first and second clamping components to work together to ensure the stability of the fan body when the user runs, tilts, or turns, thus freeing the user's hands. Furthermore, when the first and second clamping components are fixed, their volume creates an airflow layer between the inner and outer layers of the user's clothing or between the clothing and the skin, allowing the fan body to directly supply airflow. The airflow acts directly on the user's skin or penetrates the inner clothing (since the breathability of the inner clothing is generally better than that of the outer clothing), thus allowing airflow to move and carry away hot air or moisture close to the user's skin, improving cooling efficiency.

[0007] The rotating shaft can be a free shaft supported by a bearing or a damped rotating shaft.

[0008] The resistance parts of the clamping parts on both sides have a certain angle when they are in the clamping state. The angle can be obtained by bending and deforming one of the clamping parts, or by bending and deforming both clamping parts.

[0009] Preferably, the length of the power part is less than the length of the resistance part, so that the clamping part forms a force-saving lever structure in the clamping state.

[0010] Preferably, the snap-fit ​​plate has two relatively parallel flat parts, the shape of the snap-fit ​​groove matches the shape of the snap-fit ​​plate, and the opening of the snap-fit ​​groove has a stop edge for limiting the snap-fit ​​plate, thereby preventing relative rotation between the clamping part and the snap-fit ​​plate.

[0011] Preferably, an arc-shaped groove is formed on one end face of the resistance part for clamping, and the two arc-shaped grooves together form a clamping space, and an anti-slip component is embedded in the clamping space.

[0012] Preferably, when the first clamping component is the clamping part, the second clamping component is a clamping unit including an elastic clamping plate. The elastic clamping plate is parallel to the outer surface of the fan body, and the clamping opening direction of the elastic clamping plate is collinear with the air duct, thereby ensuring the clamping angle and clamping position of the first clamping component and the second clamping component. Compared with the claw-type clamping structure, the second clamping component allows the user to clamp and fix it to the clothing with less effort.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By making the first clamping component and / or the second clamping component multi-directionally adjustable, the fan body can be securely fixed between the inner and outer layers or between clothing and belt, freeing the user's hands. Compared with hanging fans, it can avoid the safety hazards of snagging and collision. Moreover, when worn, it can create an air circulation layer between clothing and skin, allowing the air outlet to be directly aimed at the body surface, effectively improving the utilization efficiency of airflow and heat dissipation.

[0019] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 — Figure 3 As shown, this embodiment discloses an outdoor fan, including a fan body 1, a first clamping component 2, and a second clamping component 3. The fan body 1 has an air duct 11 inside for guiding airflow, and a guide grille 111 is provided at its air outlet. The first clamping component 2 and the second clamping component 3 are respectively disposed on the outer surface of the fan body 1. The first clamping component 2 and the second clamping component 3 are configured to clamp and fix in a first direction and a second direction respectively, and the air duct 11 is located between the two clamping components.

[0021] The angle between the first direction and the second direction is 0° to 180°.

[0022] The first clamping assembly 2 includes a pair of opposing clamping parts 21, which are connected by a pivot 211 and divided into a power part 212 and a resistance part 213 by the pivot 211. A torsion spring 22 is wound around the pivot 211. The torsion spring 22 can be any existing elastic structure capable of providing clamping force to the two clamping parts 21, and is not limited here. In the clamping state, there is a certain angle between the clamping ends of the two resistance parts 213, forming a V-shaped opening. The user manually squeezes the two power parts 212 to open the resistance parts 213. After the user releases the power parts 212, the torsion spring 22 closes the power parts 212 by its own elastic force, thereby completing the clamping action.

[0023] The length of the power unit 212 is less than the length of the resistance unit 213, so that the torsion spring 22 forms a force-saving lever structure when providing clamping force, so as to maintain the stability of clamping and fixing.

[0024] like Figure 2 As shown, the first clamping assembly 2 is rotatably connected to the fan body 1 via a rotating member 4. The rotating member 4 includes a rotating shaft 41 and a snap-fit ​​plate 42. A slot 214 is provided on the back side (i.e. the side closer to the fan body 1) of one of the clamping parts 21. The shape of the slot 214 matches the shape of the snap-fit ​​plate 42 on the rotating member 4, so that the first clamping assembly 2 can be quickly installed onto or removed from the snap-fit ​​plate 42 through the slot 214.

[0025] To prevent relative rotation after installation, the snap-fit ​​plate 42 has two relatively parallel flat parts 421, the shape of which matches the snap-fit ​​groove 214. Furthermore, an inwardly extending baffle 215 is provided at the opening of the snap-fit ​​groove 214 so that the snap-fit ​​plate 42 is inserted and the snap-fit ​​groove 214 is stopped.

[0026] The rotating shaft 41 is a damped rotating shaft so that it can be kept in the desired position after the angle is adjusted, and its resistance is greater than the overall weight of the device.

[0027] An arc-shaped groove 216 is provided on the end face of the resistance part 213 for clamping. When the two clamping parts 21 are closed, the arc-shaped grooves 216 on both sides together form a clamping space. An anti-slip element 217 is embedded in the clamping space. The anti-slip element 217 is a silicone pad, which is used to increase friction and prevent the first clamping component 2 from sliding off when clamped on a smooth fabric.

[0028] Specifically, such as Figure 3 As shown, the first clamping component 2 is a clamping part 21, and the second clamping component 3 is a clamping unit including an elastic clamping plate 5; or, it is a clamping part 21 with the same structure as the first clamping component 2.

[0029] When the second clamping assembly 3 is a clamping unit including the elastic clamping plate 5, the second clamping assembly 3 can be composed of the elastic clamping plate 5, a connecting seat 31 integrally injection molded with the fan body 1, and a fastening screw 32 penetrating the elastic clamping plate 5. The elastic clamping plate 5 and the outer surface of the fan body 1 are fixedly connected by the connecting seat 31 and the fastening screw 32 penetrating the elastic clamping plate 5. Alternatively, the second clamping assembly 3 can be composed of only the elastic clamping plate 5. In this case, the elastic clamping plate 5 can be threadedly fixed to the fan body 1 by the fastening screw 32, or it can be rotatably connected to the fan body 1 by the rotating part 4.

[0030] The elastic clamp 5 is made of any existing elastic material, such as spring steel or plastic, and is not limited here. The elastic clamp 5 is set parallel to the outer surface of the fan body 1, and its clamping opening direction is collinear with the airflow direction of the air duct 11. The outer surface of the fan body 1 has anti-slip texture corresponding to the position of the elastic clamp 5.

[0031] When the elastic clamp 5 is rotatably connected by the rotating part 4, the rotating shaft 41 can be powered by any existing method of achieving rotational transmission. For example, one axial end of the rotating shaft 41 is fixedly connected to the outer surface of the fan body 1, and the snap-fit ​​plate 42 is rotatably connected to the other axial end of the rotating shaft 41. A stepped groove is provided on the inner side of the elastic clamp 5 (i.e. the side close to the fan body 1). When the elastic clamp 5 is snapped into the snap-fit ​​plate 42 through the stepped groove, the relative rotation between the elastic clamp 5 and the fan body 1 is realized.

[0032] Users can pass clothing directly through the gap between the elastic clamp 5 and the fan body 1. Compared with the structure of the first clamping component 2, the operation is simpler and less strenuous.

[0033] When the user needs to cool down, adjust the angle of the first clamping component 2, clamp and fix the resistance part 213 of the clamping part 21 to the inner clothing, and then fix the second clamping component 3 to the outer clothing; or, clamp and fix the resistance part 213 of the clamping part 21 to the waist belt, and then fix the second clamping component 3 to the upper garment.

[0034] When the first clamping component 2 and the second clamping component 3 are fixed together, their own structural volume can push the outer layer of clothing away from the inner layer of clothing or the user's body surface, thereby creating an air circulation layer between the inner and outer layers of clothing or between clothing and skin. At this time, the air guide grille 111 on the fan body 1 faces into the air circulation layer, and the air outlet of the air duct 11 directly enters the air circulation layer to flow, thereby removing the hot air and moisture accumulated near the user's skin. Since the airflow directly acts on the user's body surface or inner clothing, and the inner clothing is usually more breathable than the outer clothing, this solution can improve the utilization efficiency of airflow and the heat dissipation effect compared to the traditional method of placing the fan body 1 on the outside of the user's clothing.
