Description

Atomizing cooling fan

TECHNICAL FIELD

The utility model relates to the field of cooling devices, in particular to an atomizing cooling fan.

Prior art prior to the present invention

The atomizing cooling fan is a cooling fan composed of a combination of an atomizing system and a fan. The purpose of the atomizing system is to make the water blow out from the fan after being atomized and diffuse into the air, and then quickly evaporate in the air. Take away the heat in the air to achieve the cooling effect. The atomizing systems currently used in fans are: 1. High-pressure pump; 2. Nozzle; 3. Filter; 4. Water system. Its working principle is: The high-pressure pump sends water through the waterway system and the nozzle is sprayed out at high speed to produce an atomizing effect. Because the diameter of the nozzle is small, the water quality must be kept clean when spraying to avoid nozzle clogging, so the water needs to be filtered, and the entire waterway system is under high pressure, and the materials for the waterway system and the high-pressure pump are required. It is high and has high requirements on the structure. At the same time, the adjustment of the atomization size can only be achieved by replacing the nozzles of different diameters and adjusting the pressure of the high-pressure pump, so it will be limited. Therefore, the entire system has high cost, complicated process, difficult maintenance, and inconvenient adjustment of the atomization size.

Object of the invention

In order to solve the above problems, an object of the present invention is to provide an atomizing cooling fan with simple structure, convenient adjustment, simple maintenance, and good atomizing effect.

Technical solution adopted by the present invention

The purpose of the present utility model is achieved as follows: An atomizing cooling fan includes a fan, an atomizing system and an electrical system, characterized in that the atomizing system includes an atomizing motor placed at the front end of the fan, and Motor-driven rotating disc atomizer, water tank with submersible pump, and water pipeline system for water supply and return. A conical block is fixed coaxially behind the atomizing plate of the disc atomizer. The outlet of the outlet pipe is located above the conical block.

The atomizing disc of the disc atomizer is in the form of a multi-stage corrugation.

The water supply pipe in the water delivery pipeline system is provided with a regulating valve.

Because the utility model adopts a disc atomizer instead of a nozzle, the atomization effect is good, and there is no special requirement for water quality, and complicated filtering systems and protection requirements are eliminated. The installation process and manufacturing process are relatively simple, and The entire waterway system is under low pressure, so the material requirements and structure requirements for the waterway system and pump are not high. The submersible pump only performs the function of conveying water, does not need to generate high pressure, and uses very little power. (Save electricity), noise has no impact on the outside world, does not take up external space, and is inexpensive. At the same time, the disc atomizer is dragged by a separate motor, thereby becoming an independent atomization system device. It is installed at the front of the wind net in front of the fan and can be combined with various types of fans to become an atomization cooling fan. Can also be combined with different fans.

As shown in FIG. 1, the utility model is an atomizing cooling fan, which is composed of an atomizing system and a fan. The fan is driven by a fan motor 11. As shown in FIG. 2, the atomization system includes an independent disc atomizer 1, an atomization motor 16, a submersible pump 6, a water tank 5, and a water pipeline system for water supply and return. The shell 13 of the disk atomizer 1 is connected to the front wind net 12 of the fan by screws, so that the entire disk atomizer 1 is installed at the front of the fan. In order to reduce the force on the wind net 12, the disk atomizer 1 Thin-walled and plastic parts are mainly used. The atomizing disk 19 is made into a multi-stage wave form. It is stamped and formed from a stainless steel sheet. It is light in weight and has a small load. Therefore, the power of the drag motor is also very small. Shaft mounted cone 17 and baffle 18. The edge linear speed of the atomizing disk 19 has a decisive factor for the atomization effect. Due to the limitation of the fan size, the atomizing disk cannot be made very large. In order to achieve a large linear speed, the speed of the motor that pulls the atomizing disk must be high. . For fans, due to noise, vibration and other restrictions, the speed of the motor used is generally below 1500 rpm. Therefore, in the present invention, the atomizing motor 16 that pulls the atomizing disk is independent. The atomizing motor 16 is mounted on the back of the casing 13. The motor shaft is made of stainless steel. The casing 13 and the baffle plate 18 together form a waterproof effect on the atomizing motor 16, so the motor does not need special protection. The safety net 20 is installed on the front of the casing 13 and is made of plastic sprayed or stainless steel, mainly to ensure the safety protection of the atomizing disc 19. The interface 14 is installed on the outer shell 13 and is connected to the water supply pipe 3 on the outside and the water outlet pipe 15 on the inside. The water outlet of the water outlet pipe 15 is located above the conical block 17. The water collecting pan 21 uses plastic parts and is installed on the lower edge of the casing 13 with screws. The water collecting place is connected to the return pipe 2. The connection with the casing can change the installation position. When the fan has a certain tilt, it can ensure the water collecting effect. For floor fans and wall fans. As shown in FIG. 3, the micro submersible pump 6 is disposed in the water tank 5 or the water tank 36 shown in FIG. 4. A regulating valve 4 is provided on the water supply pipe, which The function is to adjust the flow of water to control the size of the atomization, and the adjustment is simple and convenient. The power cord of the electrical system and the water pipe of the water delivery pipeline system are connected to each other by plug-in connectors, which is convenient for connection and disassembly.

The working principle of the atomizing system is: The micro submersible pump 6 provided in the water tank 5 (or 36) draws water from the water tank, passes the regulating valve 4 in the water system, and controls the flow of water, and then enters the disc atomizer 1. Water falls on the rotating conical block 17 driven by the atomizing motor 16. Under the action of centrifugal force, water will flow along the conical block 17 into the atomizing disc 19, and the water droplets will become smaller after several stages of decomposition of the atomizing disc. And the speed is increased, when reaching the edge of the atomizing disk, the water droplets are very small and the speed is very high. After leaving the edge of the atomizing disk, the water droplets rush to the toothed area of the casing 13 so that the water droplets are smaller and formed Misty. The excess water is collected by the water collecting tray 21 and flows back to the water tank through the return pipe 2. The atomization system is an independent system device. In addition to being used in fans, it can also be conveniently used in fans. Example 1

The power line 28 of the micro submersible pump and the input power line 7 of the whole machine are installed on the rear cover 27 of the square column, and they are connected to a connector 29. Connectors 29 and 30 are a set of electrical combination plug-ins. When assembling, connectors 29 and 30 only need to be mated to complete the connection of the entire product electrical circuit. The water pipeline is divided into three sections. The first section of pipeline 22 is from the atomizer 1 to the upper joint group 23 of the square column; the second section of pipeline 24 is fixed in the square column and connects the upper connector group 23 and the lower connector group 25; the third section of pipeline 26 From the square column lower joint group 25 into the water tank 5 '. Two sets of connectors 23 and 25 are installed on the upper and lower parts of the square column, two in each group, one for water supply and one for backflow. During assembly, as long as the pipe of the atomizer and the pipe in the water tank are respectively connected to the corresponding joints on the square column, the water pipeline connection of the entire product is completed. The regulating valve 4 is installed in a square column and connected between the upper and lower joints of the water supply pipe in the square column.
