Description

Technical Field

[0001] This application relates to the field of electric fan technology, and in particular to an electric fan with a spray function. Background Technology

[0002] Electric fans are a common cooling tool in everyday furniture. Traditional electric fans rely on the principle of forced convection. In dry environments with relative humidity below 30%, the air heat capacity ratio is significantly reduced, resulting in limited heat removal per unit volume of airflow.

[0003] The existing patent document "CN212389587U A kind of atomizer fan" discloses a fan. Although the fan in the above technical solution has the function of spraying water mist, there is a dilemma in the actual implementation and use: although the piezoelectric ceramic atomizer can achieve low noise operation, its atomization volume is usually low and cannot meet the basic cooling needs of large indoor spaces; while using a booster pump of 40W or more can increase the atomization volume, but it will generate more noise and be accompanied by volume expansion, which seriously violates the development trend of miniaturization and quietness of household appliances.

[0004] Meanwhile, conventional atomizing blower equipment also suffers from the phenomenon of unevaporated atomized water droplets being directly dispersed during use, resulting in water waste and damp ground.

[0005] In other words, existing technologies have the following technical problems: ordinary fans either fail to produce sufficient water mist or are noisy and bulky. Therefore, to address these issues, an electric fan with a misting function is proposed. Summary of the Invention

[0006] This embodiment provides an electric fan with a spray function to solve the problems of insufficient water mist or excessive noise and size of ordinary fans in the prior art.

[0007] According to one aspect of this application, a spray-function electric fan is provided, the spray-function electric fan comprising:

[0008] A fixed platform, wherein a water tank is fixedly connected to the bottom surface of the fixed platform, and brackets are fixedly connected to both sides of the upper surface of the fixed platform.

[0009] A blower power assembly is disposed at a bracket and rotatably connected to the bracket, and the blower power assembly is used to generate a blower airflow.

[0010] The atomizing component is fixedly installed at the center of the blower power component. The atomizing component is directly connected to the water tank. The atomizing component includes an air pump, a water pipe, a nozzle, and an air pipe. The air pipe and the water pipe converge at the nozzle and are directly connected to the nozzle.

[0011] A condensation recovery assembly is fixedly mounted on the upper surface of a fixed base, and is used to condense and recover water mist in the air.

[0012] Furthermore, a slot is provided on the side of the water tank, and buckles are hinged on both sides of the fixing base.

[0013] Furthermore, the blower power assembly includes an air duct, a front cover, a rear cover, a motor, and fan blades. The air duct is disposed between two supports and is rotatably connected to the supports. The front cover is fixedly connected to the front end of the air duct, and the rear cover is fixedly connected to the rear end of the air duct.

[0014] Furthermore, a motor is fixedly connected inside the air duct, and a fan blade is fixedly connected to the end of the motor's output shaft.

[0015] Furthermore, the atomizing assembly also includes a partition, a control board, an air pump base and an air pump, the fixing bracket is fixedly installed on the inner wall of the air duct, a nozzle is fixedly connected to the middle of the fixing bracket, and one end of the water pipe extends into the inner cavity of the water tank.

[0016] Furthermore, the partition is fixedly installed on the upper surface of the water tank, and an air pump base is fixedly connected to the upper surface of the partition. An air pump is fixedly connected to the air pump base, and the output end of the air pump is connected to one end of an air pipe.

[0017] Furthermore, a control board is fixedly connected to the upper surface of the partition, and the control board integrates a temperature and humidity sensor and a wireless communication module.

[0018] Furthermore, the condensation recovery assembly includes a fixed shell, an annular fixed bracket, a condensation plate, and a flow guide groove. The fixed shell is fixedly disposed on the upper surface of the fixed platform, and the annular fixed bracket is fixedly connected to the upper surface of the fixed shell.

[0019] Furthermore, a number of condensing plates are fixedly connected to the inner wall of the fixed shell, and each of the condensing plates is provided with a guide groove.

[0020] Furthermore, the annular fixed bracket has a flow channel inside, in which a sponge filter block is fixedly installed. A return channel is opened at the bottom wall of the inner cavity of the fixed shell, and one end of the return channel extends into the inner cavity of the water tank.

[0021] To address the problem of insufficient cooling effect of ordinary electric fans in high-temperature and dry environments, this application incorporates an atomizing component. This component, in conjunction with the blowing power component, automatically sprays air during operation. The evaporation of water mist absorbs heat, and combined with airflow circulation, accelerates air cooling and increases the feeling of coolness. Compared to ordinary piezoelectric ceramic sprayers in the prior art, this application offers a larger spray volume and higher cooling efficiency. Compared to booster pump sprayers, this application is smaller and quieter, making it particularly suitable for home use. Furthermore, this application includes a condensation recovery component, which further recovers unevaporated water mist from the air, resulting in greater water conservation compared to ordinary spraying equipment and making it suitable for widespread adoption.

[0042] Please see Figure 1-8 As shown, an electric fan with a spray function includes:

[0043] A fixed base 2 is provided, with a water tank 1 fixedly connected to the bottom surface of the fixed base 2, and brackets 3 fixedly connected to both sides of the upper surface of the fixed base 2.

[0044] A blower power assembly 4 is disposed at the bracket 3 and rotatably connected to the bracket 3. The blower power assembly 4 is used to generate a blower airflow.

[0045] Atomizing component 5 is fixedly installed at the center of blower power component 4. Atomizing component 5 is directly connected to water tank 1. Atomizing component 5 includes air pump 507, water pipe 503, nozzle 502 and air pipe 508. Air pipe 508 and water pipe 503 converge at nozzle 502 and are directly connected to nozzle 502.

[0046] The condensation recovery component 6 is fixedly installed on the upper surface of the fixed base 2, and is used to condense and recover water mist in the air.

[0047] Through the above technical solution, by using the atomizing component 5 in conjunction with the blowing power component 4, spraying can be automatically performed during blowing. The water mist evaporation absorbs heat and, combined with airflow circulation, can accelerate air cooling and increase coolness. At the same time, compared with the ordinary piezoelectric ceramic spray in the prior art, the spray volume of this application is larger and the cooling efficiency is higher. Compared with the booster pump spray, this application is smaller in size and quieter, making it particularly suitable for home use. Furthermore, this application also sets up a condensation recovery component 6, which can further recover the unevaporated water mist in the air, making it more water-saving than ordinary spray equipment.

[0048] The water tank 1 has a slot on its side, and the fixed base 2 has buckles 201 hinged on both sides. With this technical solution, the buckles 201 can be engaged with the slots on the side of the water tank 1 to achieve the function of fixing. The buckle connection makes disassembly convenient.

[0049] The water tank 1 is equipped with a water inlet and a drain valve for injecting water.

[0050] The blower power assembly 4 includes an air duct 401, a front cover 402, a rear cover 403, a motor 404, and fan blades 405. The air duct 401 is disposed between two supports 3 and is rotatably connected to the supports 3. The front cover 402 is fixedly connected to the front end of the air duct 401, and the rear cover 403 is fixedly connected to the rear end of the air duct 401.

[0051] A motor 404 is fixedly connected in the inner cavity of the air duct 401, and a fan blade 405 is fixedly connected to the end of the output shaft of the motor 404. Through this technical solution, the operation of the motor 404 can drive the fan blade 405 to rotate, thereby generating airflow output.

[0052] The atomizing component 5 also includes a partition 504, a control board 505, an air pump base 506 and an air pump 507. The fixing frame 501 is fixedly installed on the inner wall of the air duct 401. A nozzle 502 is fixedly connected to the middle of the fixing frame 501. One end of the water pipe 503 extends into the inner cavity of the water tank 1.

[0053] The partition 504 is fixedly installed on the upper surface of the water tank 1. An air pump base 506 is fixedly connected to the upper surface of the partition 504. An air pump 507 is fixedly connected to the air pump base 506. The output end of the air pump 507 is connected to one end of the air pipe 508. Through this technical solution, the operation of the air pump 507 can generate a high-speed airflow. When the air passes through the spray head at high speed, the airflow speed increases, resulting in a local pressure decrease, i.e., negative pressure, thereby drawing water up from the water tank. The high-speed airflow shears and breaks the water flow into micron-sized droplets, forming a water mist that is sprayed out. Combined with the airflow generated by the blower power component 4, the function of large-area water mist evaporation and cooling is achieved.

[0054] A control board 505 is fixedly connected to the upper surface of the partition 504. The control board 505 integrates a temperature and humidity sensor and a wireless communication module.

[0055] The condensation recovery assembly 6 includes a fixed shell 601, an annular fixed bracket 602, a condensation plate 603, and a guide channel 604. The fixed shell 601 is fixedly disposed on the upper surface of the fixed platform 2, and the annular fixed bracket 602 is fixedly connected to the upper surface of the fixed shell 601.

[0056] A plurality of condensing plates 603 are fixedly connected to the inner wall of the fixed shell 601. Each of the condensing plates 603 is provided with a guide groove 604. The condensing plates 603 are made of 6061 aluminum alloy anodized parts with a thermal conductivity ≥160W / (m·K).

[0057] The annular fixed bracket 602 has a flow channel 605 inside, and a sponge filter block 606 is fixedly installed in the flow channel 605. A return channel 607 is opened at the bottom wall of the inner cavity of the fixed shell 601. One end of the return channel 607 extends into the inner cavity of the water tank 1. With this technical solution, when the blower power assembly 4 is working, the external airflow is drawn into the inner cavity of the air duct 401 through the rear cover 403 and then output by the front cover 402. When the airflow is drawn into the air duct 401, it will also flow through the condensation recovery assembly 6. When the unevaporated water mist hits the condensation plate with the airflow, the water mist is converted into liquid due to the low temperature of the plate. It condenses and gathers to form liquid droplets. The liquid droplets flow with the guide groove to the flow channel 605 and are filtered by the sponge filter block 606. Finally, they enter the inner cavity of the fixed shell 601 and flow back to the inside of the water tank 1 through the return channel 607, realizing the function of automatic water mist recovery.

[0058] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
