Specifically, the fan body 1 comprises a fan column 101 and a blowing head 102 connected to the fan column 101, the fan body 1 also comprises a base 103, the fan column 101 is connected to the base 103, so that the base 103 supports the whole of the fan body 1, the blowing head 102 comprises a fan motor and fan blades, the fan motor drives the fan blades to rotate to form a wind flow, and a fan cover is also arranged outside the fan blades, and the fan cover wraps the fan blades inside to achieve a safety effect.

[0046] The fan column 101 is connected to the base 103 and coincides with the central axis of the base 103, that is, the center of gravity of the hair dryer head 102 and the fan column 101 is located at the center of the base 103, with good stability and not prone to tipping over; a first moving wheel 104 is provided under the base 103, which is conducive to the flexible movement of the local refrigeration device to different positions for use.

[0047] like Figures 2 to 9 as well as Figures 11 to 14 As shown, the air conditioning component 2 includes a housing 201, and the housing 201 is provided with a mounting groove 2011. One combination of the fan body 1 and the air conditioning component 2 is to overlap and use them, such as Figure 1 As shown, when the fan body 1 and the air-conditioning component 2 are used in combination, the fan column 101 is correspondingly installed in the assembly groove 2011; a refrigeration component is arranged in the shell 201, and an air outlet pipe is connected to the shell 201, one end of the air outlet pipe is connected to the refrigeration component, and the other end of the air outlet pipe extends close to the blowing head 102, that is, the cold air from the refrigeration component is output to the area where the blowing head 102 forms the wind flow, and the cold air after cooling by the refrigeration component is discharged from the air outlet pipe and is blown outward under the drive of the wind flow formed by the blowing head 102. Therefore, the close area where the wind flow is sensed will feel the cold air, and the cooling effect in the close range is good.

[0048] In the present embodiment, the fan column 101 is in the shape of a straight rod; the assembly groove 2011 is arranged to penetrate along the axial direction of the shell 201, and extends into the recess along the radial direction of the shell 201, the width dimension of the assembly groove 2011 is greater than the diameter dimension of the fan column 101, and when the air-conditioning component 2 is used in combination with the fan body 1, the shell 201 is placed on the base 103, and the assembly groove 2011 is embedded in correspondence with the fan column 101, so that when the air-conditioning component 2 is stacked on the base 103 of the fan body 1, the assembly groove 2011 can be aligned with the fan column 101 for embedding and placement; the shell 201 is cylindrical, and the ratio between the diameter and the height of the shell 201 is 1:1.2~1.8. In the present embodiment, the ratio between the diameter and the height of the shell 201 is 1:1.3, because it was found in many tests that this proportion structure of the shell 201 has good stability when stacked on the base 103, and the overall structure is also more beautiful and compact.

[0049] The side wall of the housing 201 is provided with a hand insertion position 2015, which is convenient for carrying the housing 201.

[0050] A first air inlet 2012 is provided on the shell 201; the refrigeration component includes a compressor 3, a condenser 4, a throttling device and an evaporator 5; the compressor 3 drives the refrigerant to circulate between the condenser 4, the throttling device and the evaporator 5; the first air inlet 2012 corresponds to the evaporator 5, the evaporator 5 is connected to the first fan 6, the first fan 6 is connected to one end of the output pipe 7, and the other end of the output pipe 7 is connected to the air outlet pipe fitting; after the first fan 6 is started, a wind flow is formed to allow the surrounding air to enter from the first air inlet 2012 and flow through the evaporator 5 to complete the refrigeration, and then be transported to the air outlet pipe fitting via the output pipe 7; the evaporator 5 adopts hydrophilic aluminum foil and high-efficiency inner spiral copper tube to improve the evaporation effect and reduce energy consumption.

[0051] like Figure 7 As shown, the condenser 4 includes an alloy tube 401 for the flow of refrigerant, and a microporous spray component 402 is provided on the alloy tube 401. The microporous spray component 402 is connected to a water tank. Water in the water tank is drawn into the micropores of the microporous spray component 402 to spray the alloy tube 401, so as to improve the heat exchange efficiency, reduce the exhaust pressure and condensation power consumption, and thus reduce energy consumption.

[0052] The air outlet pipe fitting includes an air outlet hose 8 and an air outlet nozzle 9 connected to the air outlet hose 8. The air outlet hose 8 is made of plastic and has a certain degree of softness, which is conducive to the matching use of different hair dryer heads 102 within a certain height range, and is also conducive to adjusting the air outlet direction of the air outlet nozzle 9. The air outlet hose 8 is connected to the output pipe 7; the air outlet nozzle 9 is rotatably assembled on the air outlet hose 8, so that the air outlet nozzle 9 can be set to a horizontal or vertical shape, so that the cold air is blown out horizontally or vertically.

[0053] The air outlet hose 8 is provided with a hanging part 10 for fixing to the blow head 102. The upper end of the air outlet hose 8 is suspended on the blow head 102 by the hanging part 10, so that the air outlet nozzle 9 is close to the wind flow of the blow head 102, so as to blow out the cold air from the air outlet nozzle 9.

[0054] The shell 201 is provided with a second air inlet 2013, the condenser 4 is connected with a second fan 11, and the outer wall of the shell 201 is provided with an air outlet 2014; after the second fan 11 is started, a wind flow is formed, so that the surrounding air enters the shell 201 from the second air inlet 2013, passes through the condenser 4 and is finally blown out from the air outlet 2014, so that the internal heat of the shell 201 is discharged; Figures 2 to 5 As can be seen, the first air inlet position 2012 and the second air inlet position 2013 are both configured to be filter meshes, which are helpful to filter and isolate large impurities in the air to prevent them from entering the interior of the housing 1; and the first air inlet position 2012 and the second air inlet position 2013 are respectively located on both sides of the inner wall of the assembly slot 2011; that is, as shown in the figure, the housing 201 is formed in a U shape, and the assembly slot 2011 is an opening of the U shape; the second air inlet position 2013 is located on one side of the opening, and the first air inlet position 2012 is located on the other side of the opening; first, the first air inlet position 2012 is The second air inlet position 2013 is respectively located on both sides of the inner wall of the assembly groove 2011, thereby achieving a certain concealment and aesthetic effect; secondly, the air outlet position 2014 is located on the outer wall of the shell 201 away from the second air inlet position 2013, that is, the heat dissipation channel formed from the second air inlet position 10 to the air outlet position 2014 is U-shaped, and the surrounding air enters the shell 1 from the second air inlet position 10 and is finally blown out from the air outlet position 11. At this time, the flow of air inside the shell 1 is U-shaped, which basically passes through the internal space of the shell 1, which helps to completely blow out the heat in the shell 1.

[0055] The first air inlet position 2012 and the air outlet position 2014 are staggered in height at the shell 201, with the second air inlet position 2013 located at the top and the air outlet position 2014 located at the bottom. This can prevent the airflow entering from the first air inlet position 2012 and preparing to flow to the evaporator 5 from being discharged from the air outlet position 2014, and helps to cool the air entering from the first air inlet position 2012 as much as possible, thereby reducing airflow losses.

[0056] Moreover, the ratio of the height dimension of the area occupied by the first air inlet 2012 to the height dimension of the shell 201 is 1 / 2 to 5 / 6, that is, the first air inlet 2012 occupies a larger area on the side wall of the assembly groove 2011, which helps a larger area of ​​air flow to enter the first air inlet 2012 for heat dissipation, thereby improving the heat dissipation effect.

[0057] Fig.10The present invention is a three-dimensional diagram of the combination of the fan body 1 and the air-conditioning component 3. At this time, the air-conditioning component 2 has a second movable wheel 12, that is, the air-conditioning component 2 can also be moved and used by the second movable wheel 12. The shell 201 is also connected to the power cord 13, and the access end of the power cord 13 is located in the assembly groove 2011. The access end of the power cord 13 is located in the assembly groove 4, and the assembly groove 4 has the function of storing the power cord 13.

[0058] The structural feature of the air-conditioning fan combined local refrigeration device is that, through the organic combination of the fan body 1 and the air-conditioning component 2, the fan body generates flowing wind, and the air-conditioning component 2 provides cold air, mainly for indoor, outdoor open spaces or a large indoor specific space environment, only cooling the close range of people or objects in need, that is, cooling and cooling the local area in need; the process of heat transfer is to transfer the cold away from the area of ​​people or objects to the close range of people or objects through the air-conditioning component 2, thereby achieving the purpose of targeted cooling.

[0059] This local cooling device does not need to consider "taking heat (cold) from the outside and moving it indoors", but only cools a certain range of objects, without considering indoor and outdoor heat exchange. That is, the cold energy in the distant area is moved to the close range of people or objects to achieve the purpose of cooling the target area.

[0060] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
