Description

Technical Field

[0001] This utility model relates to the field of portable air-cooled devices, and more particularly to a portable air conditioner. Background Technology

[0002] In recent years, global warming has led to increasingly frequent and intense heatwaves. During summer, many regions experience prolonged periods of extreme heat, such as Central China and the Jiangnan region, where high humidity often results in perceived temperatures exceeding 40°C.

[0003] Traditional evaporative cooling technology lowers air temperature by allowing water to evaporate on a specially designed evaporation medium (such as a honeycomb absorbent material) and absorb heat. It is widely popular due to its simple structure, low cost, ability to produce naturally cool air, and good cooling performance in dry environments.

[0004] These traditional portable fans (or portable chillers) typically come with a small water tank, allowing air to pass through a humid evaporative medium for cooling. The portable air cooler contains a small, high-efficiency fan, driven by a motor to rotate the fan blades and create rapid airflow. The fan speed determines the airflow, which can usually be controlled by adjusting the motor voltage or using a multi-speed setting to ensure effective delivery of cooled air to the user. In addition to battery power, it also features USB ports for convenient external power supply from power banks, computer USB ports, etc., increasing the device's flexibility. The casing is made of lightweight materials, such as plastic, reducing overall weight while ensuring sufficient strength to withstand impacts during daily carrying and use.

[0005] However, traditional portable fans may fail to achieve the expected cooling effect, or their performance may be unstable under different environmental conditions (such as high temperature and high humidity), which may result in the product failing to meet users' cooling needs and affecting the product's market competitiveness.

[0006] Therefore, developing a portable air conditioning structure with stronger wind power and higher cooling efficiency has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0060] This utility model provides a portable air conditioner, in conjunction with reference to [the relevant literature]. Figure 1 and Figure 2 , Figure 1 A cross-sectional schematic diagram of a portable air conditioner conforming to this utility model is shown. Figure 2 An exploded view of the structure of the hollow air duct assembly, the arrangement of the booster fan and the fan, and the structure of the guide fan and fan at the air outlet is shown. The portable air conditioner includes: a hollow air duct assembly 2, a hollow fixing component 3, a housing 1, several sets of booster fans and fans 4, a blower fan and fan 5, a guide fan and fan 6, an air inlet 7 and an air outlet 8, an evaporation medium assembly 9, a water tank 10, a water pump 11, a water pipe 12, and a nozzle 13.

[0061] The air duct assembly is connected to the outer shell 1 via the hollow fixing member 3; the hollow air duct assembly 2 has recessed edges forming a plurality of annularly arranged grooves 21, such as... Figure 2 As shown; the outer casing 1 and the air duct assembly define a plurality of air outlet channels that extend vertically and are arranged in a ring.

[0062] Several sets of booster fans and fans 4 are fixed in each of the air outlet channels by the hollow fixing parts 3. The air inlet 7 and the air outlet 8 are located at both ends of the hollow air duct assembly 2. The drive fan and fan 5 are mounted on the base 11 of the housing, and the guide fan and fan 6 are mounted at the air outlet 8.

[0063] An evaporating medium assembly 9, a water tank 10, a water pump 11, a water pipe 12, and a nozzle 13 are disposed within the inner cavity of the hollow air duct assembly 2. The evaporating medium assembly 9 is fixed to the inner wall of the hollow air duct assembly 2 near the air outlet 8; the water tank 10 is located below the evaporating medium assembly 9 and fixed within the outer casing 1; the water pump 11 is disposed within the water tank 10; one end of the water pipe 12 is connected to the water pump 11, extending along the inner wall of the hollow air duct assembly 2 above the evaporating medium assembly 9, and the other end of the water pipe 12 is connected to the nozzle 13, which sprays water onto the first surface of the evaporating medium assembly 9 near the air outlet 8; in this embodiment, the water pipe 12 penetrates the hollow air duct assembly 2 and extends above the evaporating assembly 9. Specifically, the evaporating medium assembly 9 includes an evaporating filter 91, which retains impurities in the water on the filter screen, preventing them from being sprayed out with the water vapor. Specifically, the evaporation filter 91 is composed of a mesh filled with blocky filler; the blocky filler is coarse sand, stone particles or ceramics; the mesh is woven from elastic synthetic fibers.

[0064] 4. The portable air conditioner provided by this utility model, when in use, is pumped by the water pump 11, and the water in the water tank 10 is drawn away by the water inlet pipe 12 and sprayed out from the nozzle 13. The sprayed water droplets adhere to the first surface of the lower vibrating medium assembly near the air outlet 8. Under the action of the guide fan and the fan 6, air enters from the air inlet 7 and passes upward through the evaporating medium assembly 9. When passing through the evaporating medium assembly 9, the water droplets attached to it evaporate, and then the air carrying water vapor is discharged from the air outlet 8, humidifying the surrounding environment. The air humidity is increased by natural evaporation, without producing white fog, thus avoiding problems such as white powder pollution.

[0065] In traditional portable fans, the fan and blower drive airflow to form an airflow. However, the airflow tends to disperse, creating significant turbulence. Traditional portable fans cannot prevent this dispersion, resulting in insufficient actual air pressure. This invention addresses this issue by incorporating a hollow air duct assembly 2 with recessed edges forming several annularly arranged grooves 21. After installation, the outer shell 1 and the air duct assembly define several vertically extending, annularly arranged air outlet channels, dividing the airflow driven by the fan and blower into several straight channels. A booster fan and blower 4 are installed within these outlet channels, further driving the airflow along each channel, generating higher-pressure airflow and preventing the high-speed airflow from dispersing, thus achieving higher air pressure and forming a high-speed fan.

[0066] During use, the airflow is pressurized and accelerated by the cooperation of the drive fan and fan 5, the booster fan and fan 4, and then guided by the guide fan and fan 6 to converge the airflow and flow out from the air outlet 8. This effectively reduces the turbulence in the airflow, effectively improves the utilization rate of the airflow, provides users with stronger cold air, and also achieves the effect of quiet noise reduction.

[0067] In a preferred embodiment of this utility model, the first end of the evaporation medium component 9 is fixed to the inner wall of the hollow air duct component 2 at a height lower than the second end. The water tank 10 is disposed below the first end of the evaporation medium component 9 and is used to receive water droplets falling from the second surface of the evaporation medium component 9 near the air inlet 7, so that the water droplets can be collected and recycled.

[0068] In a further embodiment, a scraper 14 is provided between the first end of the evaporation medium component 9 and the water tank 10. One end of the scraper 14 is fixedly connected to the inner wall of the hollow air duct component 2, and the other end abuts against the second surface of the evaporation medium component 9. It is used to scrape off the dust and water droplets on the surface of the evaporation medium component 9 to avoid the accumulation of dust and water droplets on the surface and reduce the evaporation efficiency of water droplets.

[0069] In a more preferred embodiment of this utility model, the evaporation medium assembly 9 further includes: rollers, a conveyor belt support 93, an evaporation membrane conveyor belt 92, and a motor; the rollers are fixed to the hollow air duct assembly 2 via the conveyor belt support 93, and the evaporation membrane conveyor belt 92 is mounted on the rollers, so that the evaporation membrane can rotate with the rollers under the drive of the motor; the evaporation filter 91 is placed inside the space enclosed by the evaporation membrane conveyor belt 92, with a narrow gap between it and the evaporation membrane conveyor belt 92, to ensure that the evaporation membrane conveyor belt 92 can move slowly under the drive of the rollers, resulting in higher water evaporation efficiency and more uniform distribution. Optionally, the material of the evaporation membrane conveyor belt 92 is polyester fiber. This allows for the modification of the water particle size, controlling the water particle size within the range of 0.5-5 μm.

[0070] In summary, the portable air conditioner provided by this utility model allows air to enter through the air inlet and pass upwards through the evaporation medium component. As it passes through the evaporation medium component, any water droplets adhering to it evaporate. The air carrying the moisture is then discharged from the air outlet, humidifying the surrounding environment. This natural evaporation increases air humidity without producing white mist, thus avoiding problems such as white powder pollution. Impurities in the water remain on the filter screen and are not sprayed out with the water vapor; they can be collected and recycled. Furthermore, the portable air conditioner of this utility model features a special narrow and long air duct. The airflow is pressurized and accelerated by the combined action of the drive fan and fan, and the booster fan and fan. The airflow is then guided by the guide fan and fan to converge and flow out from the air outlet, effectively reducing turbulence in the airflow, effectively improving the utilization rate of the airflow, solving the problem of insufficient actual air pressure at the outlet, providing users with stronger cooling air, and also achieving a quiet noise reduction effect.

[0071] It should be noted that the embodiments of this utility model have better implementability and are not intended to limit this utility model in any way. Any person skilled in the art may use the above-disclosed technical content to change or modify it into equivalent effective embodiments. However, any modifications or equivalent changes and modifications made to the above embodiments based on the technical essence of this utility model without departing from the content of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
