[0002] Hot air duct structures are widely used in industrial production, and their main function is to provide the hot air required for various process operations. The hot air duct structures on the market currently generally face the problems of uneven hot air distribution and insufficient thermal energy utilization when dealing with large-surface blow welding operations, which to a certain extent restricts the efficiency and quality of industrial production. In the traditional straight-tube hot air duct structure, the airflow is heated by the heating element and then blown directly to the working area. In actual operations, the hot air blown out by the hot air duct of this structure is often difficult to cover the entire working area, and the problem of uneven heat distribution is more prominent.

However, since the hot air duct directly discharges the hot air, it is difficult to ensure uniform dispersion of the hot air, resulting in uneven heating and affecting the processing effect. Summary of the invention

[0004] In order to solve the problem of small hot air diffusion range and uneven diffusion in the hot air pipe, the present application provides a rapid cyclone hot air pipe.

[0005] The present application provides a rapid cyclone hot air duct adopting the following technical solution:

[0006] A rapid cyclone hot air pipe comprises:

[0007] Support pipe;

[0008] A heating component is installed in the support tube, and the heating component includes a thermocouple;

[0009] The diffusion component includes a fixed seat, a cyclone blade and a collecting valve, wherein the fixed seat is installed at one end of the support tube, the cyclone blade is arranged in the fixed seat, the collecting valve is installed in the fixed seat and is located between the cyclone blade and the heating component, and the thermocouple is arranged in the middle of the opening of the collecting valve to uniformly form hot air;

[0010] The fixing component is installed at one end of the support tube away from the fixing seat, and the fixing component abuts against the heating component to fix the heating component in the support tube.

[0011] By adopting the above technical solution, a heating component is arranged in the support tube and a diffusion component including a cyclone blade is installed on one side of the support tube. After the airflow flows through the heating component, the temperature increases; and the top of the heating component is located in the middle of the collecting valve, so that the temperature of the hot air is precisely controlled when it is blown out, and after being gathered by the collecting valve, it is blown to the cyclone blade at a higher wind speed. The cyclone blade can be selected to be rotating or fixed, and the hot air is evenly diffused to the outside through the cyclone blade, so that the hot air can evenly cover the objects that need to be blown. The fixed component is installed on the other side of the support tube. While fixing the heating component, the heating component can be removed from the support tube to remove the fixed component to adjust or replace the heating component, thereby improving the applicability of the hot air pipe.

[0012] Optionally, the collecting valve has an air flow inlet and an air flow outlet, and the cross-sectional area of ​​the air flow inlet is larger than the cross-sectional area of ​​the air flow outlet to collect the air flow.

[0013] By adopting the above technical solution, the collecting valve is arranged between the heating component and the cyclone blades, and the gas discharged from the heating component is gathered to the air flow outlet, the air flow velocity is increased and the air outlet position is limited, so that the hot air is blown out with a higher flow rate, and the hot air is evenly diffused to the outside under the action of the cyclone blades.

[0014] Optionally, a clamping protrusion is provided on the inner wall of the fixing seat, and a clamping groove is provided on the side wall of the collecting valve, and the clamping protrusion and the clamping groove cooperate with each other to fix the fixing seat and the collecting valve.

[0016] Optionally, the support tube has a first fixing ring, the fixing assembly includes a second fixing ring, and the first fixing ring is connected and fixed to the second fixing ring to fix the support tube and the fixing assembly.

[0017] By adopting the above technical solution, since the tubular support tube has fewer installation connection points on both sides, adding the first fixing ring can increase the connection points on the support tube, and by connecting with the second fixing ring, the connection between the support tube and the fixing assembly is strengthened.

[0018] Optionally, the fixing component further includes an abutment sheet and an abutment rod, the abutment sheet is connected to the second fixing ring, and the abutment rod passes through the abutment sheet and abuts the heating component.

[0019] By adopting the above technical solution, the abutment sheet is used to fix the abutment rod, so that the abutment rod, the abutment sheet and the second fixing ring are connected as a whole. After connecting the fixing assembly and the support tube, the abutment rod abuts the heating assembly, thereby fixing the heating assembly in the support tube.

[0020] Optionally, an air intake gap is left between the abutment sheet and the second fixing ring.

[0021] By adopting the above technical solution and leaving an air intake gap, the air flow can pass through the fixing component and enter the heating component, thereby fixing the heating component without hindering the normal operation of the hot air pipe.

[0022] Optionally, a connection port is provided in the middle of the abutment sheet for a connection line to pass through the abutment sheet to connect to the heating component.

[0023] By adopting the above technical solution, the connection port can provide space for the connection line to pass through the fixing component, and play a role in fixing the connection line, so that the connection of the hot air pipe is more stable during use.

[0024] Optionally, the heating component has an electrical interface.

[0025] By adopting the above technical solution, the electrical interface is used for connecting the external connection line to the heating component, so that the heating component can receive external energy or be controlled externally, thereby improving the applicability of the hot air duct.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The heating component is equipped with a thermocouple in the middle of the collecting valve, so that the temperature of the hot air generated by the heating component can be accurately controlled, and under the action of the wind reflection of the collecting valve and the swirl of the cyclone blades, the hot air is evenly diffused to achieve large-area desoldering;

[0028] 2. The collecting valve is arranged between the heating component and the cyclone blades to gather the gas discharged from the heating component to the air flow outlet, increase the air flow velocity and limit the air outlet position, so that the hot air has a higher flow rate and blows out of the hot air pipe, thereby evenly diffusing the hot air to the outside;

[0029] 3. By leaving an air intake gap, the air flow can pass through the fixing component and enter the heating component, so that the normal operation of the hot air pipe is not hindered while the heating component is fixed. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present application is further described in detail below in conjunction with the accompanying drawings.

[0036] A rapid cyclone hot air pipe, referring to Figure 1 and Figure 2 , comprising a support tube 1, a heating component 2, a diffusion component 3 and a fixing component 4. The heating component 2 is installed in the support tube 1, and is used to generate hot air when air flows through.

[0037] Reference Figure 3 and Figure 4The diffusion component 3 includes a fixed seat 31, a cyclone blade 32 and a collecting valve 33. The fixed seat 31 is installed at one end of the support tube 1. The cyclone blade 32 is arranged in the fixed seat 31. It can be set to be able to rotate relative to the fixed seat 31, or fixed relative to the fixed seat 31. When it is set to rotate, the cyclone blade 32 can push the hot air to form a jet. When it is set to be fixed, the cyclone blade 32 plays a diversion role, which is conducive to the diffusion of the hot air. A cavity is formed inside the fixed seat 31. The collecting valve 33 and the cyclone blade 32 are arranged in the cavity of the fixed seat 31, wherein the collecting valve 33 is arranged between the heating component 2 and the cyclone blade 32. A snap-fit ​​protrusion 36 is added to the inner wall of the fixed seat 31, and a snap-fit ​​groove 37 is added to the side wall of the collecting valve 33. There are four clamping protrusions 36, which are evenly distributed on the fixing seat 31. The clamping protrusions 36 are elastic protrusions, which can be pushed outward when subjected to pressure, so that the clamping grooves 37 enter. The clamping grooves 37 are annular and arranged on the surface of the collecting valve 33. The clamping protrusions 36 cooperate with the clamping grooves 37, which can simply and effectively achieve a stable connection between the fixing seat 31 and the collecting valve 33, and are easy to install and disassemble. The collecting valve 33 has an airflow inlet 34 and an airflow outlet 35. The cross-sectional area of ​​the airflow inlet 34 is larger than the cross-sectional area of ​​the airflow outlet 35. This design enables the airflow to be effectively gathered and accelerated when passing through the collecting valve 33. The cyclone blades 32 are connected to the outside of the airflow outlet 35, and are connected to the collecting valve 33 through bearings, fixing parts and other components to achieve relative rotation or relative fixation. The flow rate is high, and the hot air ejected from the middle can make the airflow be diffused outward over a large range and evenly, thereby improving the diffusion performance of the hot air pipe.

[0038] Reference Figure 2 A thermocouple 22 is provided at the top of the heating component 2. The thermocouple 22 is inserted into the collecting valve 33 and is located between the air flow inlet 34 and the air flow outlet 35. When the hot air blows out the heating component 2, the temperature is accurately controlled by the thermocouple 22, which is beneficial to improving the heating accuracy of the hot air pipe.

[0039] Reference Figure 3The fixing assembly 4 is installed at one end of the support tube 1 away from the fixing seat 31, and the fixing assembly 4 includes a second fixing ring 41, an abutting piece 42 and an abutting rod 43. A first fixing ring is provided on the side of the support tube 1 close to the fixing assembly 4, and the second fixing ring 41 is connected to the first fixing ring and fixed by fasteners such as bolts to ensure a stable connection between the support tube 1 and the fixing assembly 4. The abutting piece 42 is connected to the second fixing ring 41 and is away from the heating assembly 2 relative to the second fixing ring 41. An air intake gap 44 is left between the abutting piece 42 and the second fixing ring 41. This air intake gap 44 can ensure that while fixing the heating assembly 2, it will not hinder the normal entry of airflow, thereby ensuring the smoothness of hot air diffusion. The abutting rod 43 passes through the abutting piece 42, is fixed relative to the abutting piece 42, and abuts on the heating assembly 2, thereby forming a support for the heating assembly in the support tube 1. In addition, the heating component 2 is provided with an electrical interface 21, and the electrical interface 21 is used for connecting the external connection line to the heating component 2, so that the heating component 2 can receive external energy or be controlled externally, thereby improving the applicability of the hot air duct. At the same time, a connection port is also provided in the middle of the abutting piece 42, and the connection port is used for the external connection line to pass through the fixing component 4 and connect to the heating component 2 through the electrical interface 21. In addition, the connection port can also play the role of fixing the connection line, ensuring the stable connection between the connection line and the electrical interface 21.

[0040] The implementation principle of the embodiment of the present application is as follows: during use, the airflow enters the heating component 2 from the air inlet gap 44, the heating component 2 heats the airflow to generate hot air, and after the hot air enters the diffusion component 3, it is gathered and accelerated by the collecting valve 33, and blown into the cyclone blades 32 with a higher flow rate, thereby effectively diffusing the hot air to a larger range. The fixing component 4 fixes the heating component 2 in the support tube 1. When the heating component 2 needs to be removed, it is only necessary to separate the connection between the first fixing ring and the second fixing ring 41, and then the heating component 2 can be slid out of the support tube 1 after removing the fixing component 4, which is conducive to improving the convenience of installing or removing the hot air pipe.

[0041] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
