Description

Technical Field

[0001] The utility model belongs to the technical field of air supply equipment, and particularly relates to a vertical bladeless fan. Background Art

[0002] In the prior art, bladeless fans include annular bladeless fans and vertical bladeless fans. Annular bladeless fans have a base, a body, and a circular nozzle supported by the body for discharging air. Vertical bladeless fans have a base, a body, and a vertical outlet tube for discharging air. Both annular and vertical bladeless fans generate wind from the body, which houses a motor and impeller. The wind is then transported to an outlet device above, where it is then discharged.

[0003] However, these bladeless fans typically feature a forward-directed airflow, blowing air toward the user. The vertical sweep angles of bladeless fans on the market are often fixed, limiting their airflow range. Therefore, to expand the airflow range, vertical sweep components are often added to the air duct to change the wind direction. However, the addition of these sweep components complicates the bladeless fan structure and makes it prone to dust accumulation. This also increases wind resistance and noise, resulting in a poor user experience. Utility Model Content

It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0028] Example 1

[0029] like Figure 1 and Figure 2 As shown, a vertical bladeless fan includes a column 1, a top cover 2 and a wind turbine 3, the top cover 2 is connected to the upper end of the column 1, and an air inlet chamber 21, a wind wheel chamber 22 and an air outlet chamber 23 are provided inside the top cover 2, the air inlet chamber 21 is arranged on the side where the top cover 2 is connected to the column 1, the wind wheel chamber 22 is arranged above the air inlet chamber 21, and the air outlet chamber 23 is surrounded by the wind wheel chamber 22; the wind turbine 3 is installed in the wind wheel chamber 22, and the exhaust side of the wind turbine 3 is connected to the air inlet chamber 21, and the supply side of the wind turbine 3 is connected to the air outlet chamber 23; the air inlet chamber 21 is connected to the outside atmosphere through an air inlet hole 24, and the air outlet chamber 23 gradually narrows from the inside to the outside and forms an air outlet hole 25 arranged in a circular ring around the center of the top cover 2 at the bottom of the top cover 2; a lighting device 4 is installed below or outside the top cover 2.

[0030] Thus, the vertical bladeless fan provided by the first embodiment of the present invention uses a column 1 to place a top cover 2 with a built-in wind turbine 3 at a high position. The bottom of the top cover 2 is formed with air outlet holes 25 arranged in a circular ring around the center of the top cover 2, so that the fan can achieve top-down air supply without adding upper and lower wind sweeping components, providing more uniform and comfortable wind force, and forming a wind wall around the bottom of the top cover 2, which is conducive to blocking flying insects from entering the space below the top cover 2. At the same time, because the airflow passes through the channel that gradually narrows from the inside to the outside in the radial direction of the top cover 2, according to the Bernoulli principle of fluid mechanics, the airflow speed will increase accordingly, which means that the fan can generate stronger wind force, which is conducive to accelerating the evaporation of moisture on the human body surface, making people feel cool. In addition, because the fan has no exposed blades, safety hazards are reduced. When used in outdoor scenes, the top cover 2 can also be used for sun protection and rain protection. The lighting device on the top cover can be used for lighting in low-light environments.

[0031] For example, Figure 1 As shown, the top cover 2 includes a hollow column 26, an upper cover body 27 and a lower cover body 28; the hollow column 26 is fixedly connected to the upper end of the column 1 and forms the air inlet chamber 21, and the hollow column 26 is provided with the air inlet hole 24 on the outer periphery of the side close to the column 1; the lower cover body 28 is arranged around the upper end of the hollow column 26 and is fixedly connected to the hollow column 26; the upper cover body 27 is covered above the hollow column 26 and the lower cover body 28 (when installed, the upper cover body 27 can be supported and fixed by the frame of the wind turbine 3), and the wind wheel chamber 22 is formed between the middle part of the upper cover body 27 and the hollow column 26, and the air outlet chamber 23 is formed between the outer side of the upper cover body 27 and the lower cover body 28; the upper cover body 27 is a curved cover body, and the lower cover body 28 is a curved cover body that is recessed toward one side of the upper cover body 27 and has an opening in the middle. During operation, the airflow enters the air inlet chamber 21 from the four sides of the hollow central column 26 under the action of the wind turbine 3, and converges in the wind wheel chamber 22 located in the center of the top cover 2 and then diffuses to the surrounding air outlet chambers 23. When flowing through the gradually narrowing channel of the air outlet chamber 23, the inner wall of the channel forms a smooth transition area, which effectively reduces wind resistance and ensures airflow speed.

[0032] For example, Figure 1 As shown, a lighting device 4 is installed at the bottom of the lower cover 28 to achieve lighting inside the vertical bladeless fan in a low-light environment.

[0033] For example, mosquito repellent or aromatherapy is placed in the air inlet chamber 21. When air flows through the air inlet chamber 21, it can carry odorous substances such as mosquito repellent or aromatherapy with it. The odor emitted by the mosquito repellent forms a mosquito repellent wind wall under the action of the wind wall, effectively blocking mosquitoes from entering the space below the top cover 2; and the odor emitted by the aromatherapy can improve the surrounding air.

[0034] For example, Figure 2 As shown, a table top 5 is provided in the middle of the column 1 for convenient placement of items, work or life.

[0035] For example, Figure 2 As shown, a base 6 is provided at the bottom of the column 1 to improve the stability of product placement.

[0036] For example, to make the product more suitable for outdoor use, the vertical bladeless fan also includes a battery and a photovoltaic panel. The battery's charging terminal is electrically connected to the photovoltaic panel, and the battery's power transmission terminal is electrically connected to the wind turbine 3 and the lighting device 4, respectively. The battery can be located inside the top cover 2, inside the column 1, or inside the base 6. However, due to the battery's inherent weight, to lower the product's center of gravity and ensure product stability, the battery is preferably installed inside the base 6. The photovoltaic panel is mounted or installed on the top surface of the top cover 2.

[0037] Exemplarily, the column 1 is further provided with an additional functional module electrically connected to the battery; the additional functional module includes one or more of a control panel, a Bluetooth speaker, a mobile phone charging port, and an external power port. It should be noted that the control panel is used to control the start and stop of the wind turbine 3 and the air volume, as well as the start and stop and brightness of the lighting device 4.

[0038] Example 2

[0039] like Figures 3 to 5 As shown, the main difference between the second embodiment and the first embodiment is that: the top cover 2 includes a hollow column 26, an upper cover body 27, a lower cover body 28 and an outer cover body 29; the hollow column 26 is fixedly connected to the upper end of the column 1 and forms the air inlet chamber 21, and the hollow column 26 is provided with the air inlet hole 24 on the outer periphery of the side close to the column 1; the lower cover body 28 is arranged around the upper end of the hollow column 26 and is fixedly connected to the hollow column 26; the upper cover body 27 is covered on the hollow column 26 and the upper part of the lower cover 28, and the wind wheel chamber 22 is formed between the middle part of the upper cover 27 and the hollow column 26, and the air outlet chamber 23 is formed between the outer side of the upper cover 27 and the lower cover 28; the upper cover 27 is a curved cover, and the lower cover 28 is a curved cover that is recessed toward one side of the upper cover 27 and has a hole in the middle; the outer cover 29 is covered on the upper part of the upper cover 27, and a hollow interlayer 210 is formed between the outer cover 29 and the upper cover 27. Among them, the outer cover 29 can be a curved cover, a cylindrical cover (see Figure 5) or other shaped covers. During operation, airflow, under the action of the wind turbine 3, enters the air inlet chamber 21 from around the hollow central column 26, converges in the wind wheel chamber 22 located at the center of the top cover 2, and then diffuses to the surrounding air outlet chambers 23. When flowing through the gradually narrowing channel of the air outlet chamber 23, the inner wall of the channel forms a smooth transition area, effectively reducing wind resistance and ensuring airflow speed. In addition, since a hollow interlayer 210 is formed between the outer cover 29 and the upper cover 27, the hollow interlayer 210 can be used to fill with heat insulation material or sound insulation material, and can also be used to install other equipment, such as batteries for powering the wind turbine 3 and the lighting device 4.

[0040] Further, if Figure 3 and Figure 4 As shown, in addition to the lighting device 4 installed at the bottom of the lower cover 28, a lighting device 4 can also be installed on the outside of the top cover 2 to provide lighting outside the vertical bladeless fan in low-light environments. Specifically, a light groove 211 is formed on the outside of the hollow interlayer 210, and the lighting device 4 is installed in the light groove 211.

[0041] Further, if Figure 3 As shown, the upper end of the upper cover 27 is provided with a protrusion 213, and the outer cover 29 is provided with a groove 212 that cooperates with the protrusion 213. Such a design enables the upper cover 27 to form a direct positioning support for the outer cover 29, which is easy to assemble and has a reliable structure.

[0042] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
