Description

Technical Field

[0001] The utility model relates to the technical field of axial flow fans, in particular to a high-temperature resistant and ultra-quiet axial flow cooling fan. Background Art

[0002] An axial flow fan is an airflow that flows in the same direction as the axis of the fan blades. As a general-purpose machine used on a large scale, axial flow fans are applied in all walks of life. Ordinary axial flow fans can be used for ventilation in general factories, warehouses, offices, residences and other places.

[0003] Due to the large size of the axial flow fan, in order to facilitate the movement of the axial flow fan, rollers are generally added to the bottom of the axial flow fan to facilitate the propulsion of the axial flow fan; however, during the normal use of the axial flow fan, the contact area between the roller and the ground is small, and there is a gap between the roller and the axial flow fan assembly, which makes the axial flow fan prone to shaking and generating noise during normal use. Utility Model Content

[0004] The purpose of the utility model is to provide a high-temperature resistant and ultra-quiet axial flow cooling fan in response to the above-mentioned deficiencies in the prior art.

[0005] The purpose of the utility model is achieved through the following technical solutions: a high-temperature resistant and ultra-quiet axial flow cooling fan, comprising a fixing bracket and a shell provided on the fixing bracket; a driving member and a fan blade connected to the output end of the driving member are provided in the shell; a rolling wheel is provided at the bottom of the fixing bracket;

[0007] The present invention is further configured such that the guide assembly comprises a guide sleeve provided on a fixed bracket and a guide post provided on a support plate; the guide post is slidably connected to the guide sleeve; and the guide post is sleeved in the guide sleeve.

[0008] The present invention is further configured such that the fixed bracket includes a first connecting frame and a second connecting frame, both of which are inclined; a first connecting plate is provided between the first connecting frame and the second connecting frame; the outer shell is provided with a second connecting plate; and the second connecting plate is rotatably connected to the first connecting plate.

[0009] The present invention is further configured such that a rotating shaft is provided between the first connecting plate and the second connecting plate; the second connecting plate is provided with an arc-shaped groove; and the first connecting plate is provided with a locking pin for moving in the arc-shaped groove.

[0010] The utility model is further configured such that a brake pad is provided when the rolling wheel rotates.

[0011] The utility model is further configured such that the shell is provided with a blocking net.

[0012] The utility model is further configured such that the driving member is a silent electric motor.

[0013] The utility model is further configured such that the surfaces of the fixing bracket, the housing, the driving member and the fan blades are all coated with an organic silicon high temperature resistant coating.

[0014] The beneficial effects of the utility model are as follows: the utility model rotates the hand wheel to rotate the screw in the screw hole, so that the support plate is raised and lowered along the guide assembly, so that the rolling wheel is suspended in the air.

[0020] The present invention will be further described with reference to the following embodiments.

[0021] Depend on Figures 1 to 3It can be seen that the high-temperature resistant and ultra-quiet axial flow cooling fan described in this embodiment includes a fixed bracket 1 and a housing 2 provided on the fixed bracket 1; a driving member 31 and a fan blade 32 connected to the output end of the driving member 31 are provided in the housing 2; a rolling wheel 33 is provided at the bottom of the fixed bracket 1;

[0022] The bottom of the fixed bracket 1 is provided with a support plate 4 for lifting and lowering movement; the fixed bracket 1 is provided with a screw hole; a screw rod 41 is provided for rotation in the screw hole; the bottom of the screw rod 41 is connected to the support plate 4; the fixed bracket 1 is provided with a hand wheel 42 connected to the top of the screw rod 41 for rotation; a guide assembly is provided between the support plate 4 and the bottom of the fixed bracket 1.

[0023] Specifically, the high-temperature resistant and ultra-quiet axial flow cooling fan described in this embodiment needs to fix the position of the axial flow cooling fan after it is moved; by turning the hand wheel 42, the screw 41 is rotated in the screw hole, so that the support plate 4 is raised and lowered along the guide assembly, so that the rolling wheel 33 is suspended in the air. Since the contact area between the support plate 4 and the ground is large, it can effectively prevent the axial flow cooling fan from generating noise during operation, thereby achieving a silent function.

[0024] In this embodiment of a high-temperature-resistant, ultra-quiet axial cooling fan, the guide assembly includes a guide sleeve 52 disposed on a fixed bracket 1 and a guide post 51 disposed on a support plate 4. The guide post 51 is slidably connected to the guide sleeve 52, and the guide post 51 is sleeved within the guide sleeve 52. Specifically, this arrangement facilitates the raising and lowering of the support plate 4 by the guidance of the guide post 51 and the guide sleeve 52.

[0025] In this embodiment, a high-temperature-resistant, ultra-quiet axial cooling fan is described. The fixing bracket 1 includes a first connecting bracket 11 and a second connecting bracket 12, both of which are arranged at an angle. A first connecting plate 13 is provided between the first connecting bracket 11 and the second connecting bracket 12. The housing 2 is provided with a second connecting plate 21, which is rotatably connected to the first connecting plate 13. This arrangement facilitates user adjustment of the angle of the housing 2.

[0026] In this embodiment of a high-temperature, ultra-quiet axial cooling fan, a rotating shaft 14 is provided between the first connecting plate 13 and the second connecting plate 21; the second connecting plate 21 is provided with an arcuate groove 22; and the first connecting plate 13 is provided with a locking pin 15 for movement within the arcuate groove 22. This arrangement further stabilizes the connection between the housing 2 and the mounting bracket.

[0027] In the high-temperature resistant and ultra-quiet axial flow cooling fan of this embodiment, the rolling wheel 33 is provided with a brake pad 34. With the above arrangement, when the support plate 4 is lowered, the rolling wheel 33 is first locked to prevent the axial flow cooling fan from moving when the support plate 4 is lowered.

[0028] In the high-temperature resistant and ultra-quiet axial flow heat dissipation fan described in this embodiment, the housing 2 is provided with a blocking net 23. The above arrangement can prevent large items from entering the fan blades 32.

[0029] The embodiment of the present invention is a high temperature resistant ultra-quiet axial flow cooling fan, wherein the driving member 31 is a silent motor. The above arrangement can further reduce the noise generation.

[0030] In this embodiment, a high-temperature, ultra-quiet axial cooling fan is described. The surfaces of the fixing bracket 1, housing 2, driver 31, and fan blades 32 are all coated with a high-temperature silicone coating. This eliminates the need for metal materials, which reduces the weight of the axial cooling fan. Silicone high-temperature coatings are currently available, with both organic and inorganic silicon high-temperature resistant coatings. They are resistant to high-temperature oxidation and corrosion from other media, typically to temperatures between 100°C and 800°C.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
