[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] See also Figures 1 to 7 The utility model discloses a novel heat dissipation fan, including a fan component 1, a housing 2 and a support frame 3. The fan component 1 is arranged in the housing 2. The left and right sides of the housing 2 are provided with first limit grooves 4 for fixing the support frame 3. The first limit grooves 4 are configured to allow the support frame 3 to adjust its height in the vertical direction. The top surface of the housing 2 is provided with an air outlet 202, the center of the bottom surface of the housing 2 is provided with a light-transmitting opening 201, and the outer periphery of the light-transmitting opening 201 is provided with a plurality of air outlets 206. When the fan component 1 rotates, the air is discharged from the air outlet 202.

[0044] In this embodiment, the support frame 3 is arranged in the limiting groove 4 and can be assembled in the limiting groove 4 in both directions. Figure 5 and Figure 6 As shown, the top surface or the bottom surface of the housing 2 is selected to face downward, and the buckle position 301 of the support frame 3 is installed in the assembly hole 401.

[0045] In this embodiment, the maintenance process usually involves welding, which is accompanied by smoke. Figure 5 As shown, when the top surface of the housing 2 faces upward and the air outlet 206 faces downward, the novel cooling fan can be used to exhaust smoke; Figure 6As shown, during the repair process of the mobile phone motherboard, the motherboard is usually heated and stratified. After the heating and stratification are completed, the temperature of the motherboard is high and needs to be dissipated. The top surface of the shell 2 is facing downward, that is, the air outlet 202 is facing downward, to dissipate the heat and cool the motherboard. Both smoke exhaust and heat dissipation involve the fan component 1.

[0046] In this embodiment, the support frame 3 is preferably rectangular, so that the support frame 3 can stand upright on the workbench.

[0047] In this embodiment, multiple rows of assembly holes 401 are provided in the first limiting groove 4, and the support frame 3 is provided with multiple rows of buckle positions 301 corresponding to the assembly holes 401. The buckle positions 301 are connected and fixed with different rows of assembly holes 401 to adjust the height of the support frame 3 extending out of the housing 2. Among them, each row is preferably provided with at least two assembly holes 401, and correspondingly, the number of buckle positions 301 in each row is consistent with the number of assembly holes 401, and at least two assembly holes 401 make the support frame 3 more stable when fixed to the housing 2, and multiple rows of assembly holes 401 provide the support frame 3 with support gears of different heights.

[0048] Further, such as Figures 4 to 6 As shown, the buckle position 301 of the support frame 3 is installed on the assembly hole 401, so that a part of the support frame 3 is in contact with the first limiting groove 4, and the other part is exposed outside the body of the shell 2. When the support frames 3 on both sides are engaged with the assembly holes 401 at the same position, the support frames 3 on both sides can support the entire shell 2.

[0049] Furthermore, the support frame 3 can also be assembled in both directions, such as Figure 4 , Figure 5 and Figure 6 As shown, the support frame 3 is installed on both sides of the shell 2 and extends out of the bottom / top of the shell 2. When the support frame 3 holds up the shell 2 and the air outlet 202 faces downward, the fan component 1 is started to dissipate heat and cool the mobile phone motherboard. During the process, maintenance personnel do not need to hold it, which saves manpower and time and is more convenient.

[0050] Further, such as Figure 5 As shown, when the support frame 3 extends out of the bottom of the housing 2, that is, the air inlet 206 faces downward, the support frame 3 is tilted, the side frame of the housing 2 contacts the workbench, the entire device is tilted about 45°, and the fan component 1 is started to function as a smoke exhaust fan, solving the problem that the smoke exhaust fans on the market have no tilt angle, resulting in inability to repeatedly absorb and insufficient smoke exhaust. Concentrating heat dissipation and smoke exhaust in one device avoids frequent tool changes by staff, making the maintenance process more convenient.

[0051] In this embodiment, when the support frame 3 supports the shell 2, the shell 2 can be suspended in the air and the support frame 3 can be placed on the workbench, or the support frame 3 can be tilted and the side frame of the shell 2 contacts the workbench, so that the shell 2 is placed on the workbench at an angle of about 45°.

[0052] In this embodiment, the body of the support frame 3 is further provided with a handle 302 to facilitate the support frame 3 to be loaded when being assembled or disassembled in the first limiting groove 4 .

[0053] In this embodiment, a curing lamp 6 and / or a dust-displaying lamp 7 are also included on the housing 2, making maintenance more convenient. When it comes to heat dissipation, smoke exhaust, irradiation with a curing lamp, and checking for dust on the screen, maintenance personnel do not need to frequently switch tools, thereby improving work efficiency.

[0054] Specifically, a support plate 5 is further provided in the housing 2 , and the support plate 5 is located below the fan component 1 ; the curing lamp 6 and / or the dust-displaying lamp 7 are fixed in the housing 2 via the support plate 5 .

[0055] Furthermore, in the present embodiment, a light-transmitting opening 201 is further provided at the bottom of the shell 2, and a curing lamp 6 is provided at the center of the support plate 5, and the light source of the curing lamp 6 is irradiated through the light-transmitting opening 201 at the bottom of the shell 2; in the process of repairing the mobile phone motherboard, after repairing the pads and solder joints, UV green oil is required to fix the repaired pads, and therefore, the irradiation of the curing lamp 6 is required to accelerate the curing of the UV green oil, but due to the different materials and applied amounts of UV green oil, the irradiation height of the curing lamp 6 needs to be adjusted according to actual conditions, and although some existing curing lamp products are provided with brackets, most of them are not adjustable in angle, and have poor compatibility; the novel cooling fan of the utility model is provided with a support frame 3 with an adjustable height, and the irradiation height can be adjusted as needed during maintenance, and has strong compatibility.

[0056] In addition, the curing lamp 6 is integrated with the fan component 1, which saves the maintenance personnel time in switching tools and is convenient to use. Figure 4 As shown, the side of the housing 2 provided with the light-transmitting opening 201 faces downward, and the curing lamp 6 is turned on. During this process, the worker does not need to hold the curing lamp 6, which makes it more convenient for the worker and provides a better experience.

[0057] Furthermore, in the present embodiment, dust-displaying lamps 7 are also provided on both sides of the curing lamp 6, and the light source of the dust-displaying lamp 7 is also irradiated through the light-transmitting port 201. In the process of changing the screen or applying a film on the mobile phone, the dust on the screen needs to be cleaned, and the green light of the dust-displaying lamp 7 helps to better find the dust and check the cleaning condition. However, the dust-displaying lamps in the prior art are mostly flat structures without angles, and direct irradiation can damage the eyesight of maintenance personnel. In the present embodiment, the support frame 3 can be extended to a certain height of the shell, and the support frame 3 can be tilted, the bottom frame of the shell 2 contacts the workbench, and the bottom surface of the shell 2 and the workbench are about 45°, so that the green light irradiated by the dust-displaying lamp 7 will not directly hit the eyes. The utility model integrates the dust-displaying lamp 7 with the fan component 1, which is convenient for maintenance personnel to perform a series of operations from heat dissipation, smoke exhaust, curing to screen inspection. It is easy to use and has a good experience.

[0058] In this embodiment, since the curing lamp 6 and the dust-displaying lamp 7 are arranged on the back of the support plate 5, an isolation column 10 is also provided between the support plate 5 and the bottom of the shell 2, so that a distance is separated between the support plate 5 and the bottom surface of the shell 2 to protect the curing lamp 6 and the dust-displaying lamp 7.

[0059] In this embodiment, a battery 13 for operating the fan component 1 , the curing lamp 6 and the dust-displaying lamp 7 is also provided in the housing 2 .

[0060] In this embodiment, a signal light 14 is provided below the button 9 of the control panel 8. When any of the fan component 1, the curing light 6 and the dust display light 7 is working, the signal light 14 lights up to remind the maintenance personnel of the operating status of the device.

[0061] In this embodiment, a control panel 8 is further provided in the shell 2, and a button opening 203 is correspondingly provided on the surface of the shell 2. A button 9 for controlling the switch of the fan component 1, the curing lamp 6 and the dust-displaying lamp 7 is provided on the control panel 8; further, a key cap 901 is connected to the outside of the button 9. After the shell 2 is covered, the key cap 901 passes through the button opening 203 on the surface of the shell 2, and the maintenance personnel controls the switch of the fan component 1, the curing lamp 6 and the dust-displaying lamp 7 by pressing the corresponding key cap 901.

[0062] In this embodiment, a fixing portion 801 is further provided on the side of the control panel 8, and correspondingly, a fixing hole 204 matching the fixing portion 801 is provided on the side wall of the shell 2, and the fixing portion 801 is engaged and fixed with the fixing hole 204; in order to further fix the control panel 8, a second limiting groove 205 is further provided in the shell 2, and the control panel 8 is installed in the second limiting groove 205; to ensure that when the user presses the button 9, the control panel 8 will not be skewed in the shell 2 due to external force, and is more stable.

[0063] In this embodiment, a threaded column 12 is also included. Correspondingly, a plurality of downward limiting columns 11 are also provided in the shell 2, the fan component 1 is provided with a plurality of first limiting holes 101, and the support plate 5 is provided with a plurality of second limiting holes 501; the limiting column 11 is inserted into the first limiting hole 101, and the threaded column 12 passes through the isolation column, the second limiting hole 501 and the first limiting hole 101 from bottom to top in sequence, and is threadedly connected with the limiting column 11, so that the fan component 1, the support plate 5 and the isolation column 10 are fixed without displacement or loosening.

[0064] In summary, the utility model adds a height-adjustable support frame 3 to the cooling fan. In the prior art, most cooling fans need to be held by hand. The utility model extends the support frame 3 out of the shell 2 to a certain height, and then places the shell 2 flat on a workbench for heat dissipation. This process does not require hand-holding, saving the energy of maintenance personnel. In addition, after the support frame 3 is extended out of the shell 2 to a certain height, the whole can be placed on the workbench at an angle. The function of being able to be placed flatly and at an angle makes the utility model more compatible.

[0065] In addition, repairing a mobile phone motherboard involves heat dissipation, smoke exhaust, curing light, and checking for screen dust. During the heat dissipation process, the support frame 3 is extended out of the bottom of the shell 2, and the support frame 3 is placed flat on the workbench, and the fan component 1 is started. There is no need to hold the fan in the heat dissipation process, which saves the maintenance personnel's energy; during the smoke exhaust process, the buckle position 301 of the support frame 3 is engaged with the corresponding assembly hole 401, and the entire device is tilted, preferably at 45°, with the air inlet 206 facing downward, and the fan component 1 is started, so that the gas can be fully and effectively sucked away during the welding process; after performing work on the pads, solder joints, etc., UV green oil is required to fix the repaired solder joints, and a curing lamp 6 is required for curing. The utility model integrates the commonly used curing lamp and the fan component 1 into one device, and is equipped with an adjustable height support frame 3, which is more flexible and compatible; when checking the screen dust, the dust display lamp 7 and the fan component 1 are integrated into one device, and the maintenance personnel do not need to frequently switch tools, which is more convenient to use, and the existing dust display lamp 7 is in a flat state, and direct light can easily damage the eyes of the maintenance personnel. The device can be placed at an angle to effectively avoid damage to the eyes.

[0066] Furthermore, the existing heat dissipation fan does not have the functions of the curing lamp 6 and the dust-indicating lamp 7. Integrating the curing lamp 6 and the dust-indicating lamp 7 with the fan component 1 in one device makes the maintenance process more convenient and more in line with the needs of maintenance personnel.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
