[0026] In order to clearly illustrate the scheme in the present invention, preferred embodiments are given below and described in detail with reference to the accompanying drawings. The following description is essentially only exemplary and is not intended to limit the application or use of the present disclosure. It should be understood that in all the drawings, corresponding reference numerals represent the same or corresponding parts and features.

[0027] like Figures 1 to 10 As shown, an open multi-layer heating heater provided by the present invention comprises a base 1 and a multi-layer heating unit 2 superimposed on the base 1, wherein each layer of the heating unit 2 comprises a bracket 21, a heating element 22 mounted on the bracket 21, and a centrifugal fan 23. The single heating unit 2 in the present invention is an independent heating module, and any number of heating units 2 can be combined together to meet the requirements of different heating environments. The above structure can realize the order-based processing requirements, and heaters of different heights and powers can be completed according to customer requirements.

[0028] See also Figures 1 to 10 , the above embodiment given by the present invention further includes that the lower part of each layer of the heating unit 2 forms an air inlet structure 24 for air inlet on all sides, and the upper part of each layer of the heating unit 2 forms an air outlet structure 25 for air outlet on all sides, and multiple air inlet layers 10 and multiple air outlet layers 20 are formed around the heater, and part of the air outlet layer 20 airflow in the heating unit 2 located in the next layer enters the heating unit 2 of the previous layer again. In the present invention, the heating unit 2 is an open structure, which does not have a shell, and the air inlet structure 24 and the air outlet structure 25 are both circular structures, so as to achieve 360-degree air inlet or outlet. Therefore, in the present invention, a large-area heating area is formed with the heater as the center, and the environment heats up quickly. In addition, since the heating unit 2 is a multi-layer structure, multiple heating layers are formed in the height direction, thereby increasing the heating volume. In the present invention, part of the cold airflow at the bottom layer will be repeatedly heated many times, thereby increasing the heating speed. In summary, the heater of the present invention makes the airflow softer by circumferential air outlet, and the multi-layer heating structure composed of multi-layer heating units makes the heating area larger and the heating speed faster.

[0029] See also Figures 1 to 10, further included in the above embodiment given by the present invention, also includes an air-distributing mesh tube 3, and the heating unit 2 is mounted in the mesh tube 3. The air-distributing mesh tube 3 has a blocking effect on the incoming and outgoing airflows, so that the airflow is smoother and more uniform when the air is incoming. When the air is out, due to the blocking effect, the heating temperature of the airflow is increased, and the air outlet is more uniform, forming an air outlet layer. The surrounding wall of the air-distributing mesh tube 3 is densely covered with mesh holes 31. The size and density of the mesh holes 31 can be determined according to the amount of air inlet or outlet, so that the airflow in and out is smoother, which is conducive to the uniform diffusion of the airflow. The bottom of the air-distributing mesh tube 3 is mounted on the base 1, and a folded edge is formed on the top, and the folded edge is stuck on the top of the heater.

[0030] See also Figures 1 to 10 , the above embodiment given by the present invention further includes that the bracket 21 includes a heating bracket 211 and an air guide bracket 212, the heating bracket 211 is connected to the heating element 22, and the centrifugal fan 23 is installed on the air guide bracket 212. The heating bracket 211 and the air guide bracket 212 are connected together by a plurality of pillars 213. The heating bracket 211 in the present invention is used to install the heating element 22, and the lower part of the air guide bracket 212 forms an air inlet structure 24, and the upper part forms an air outlet structure 25. The pillar 213 is formed on the heating bracket 211, and a plug is provided on the top of the pillar 213. A concave hole is formed on the air guide bracket 212, and the plug is inserted into the concave hole for easy connection. The pillar 213 plays a supporting role, so that the heating bracket 211 and the air guide bracket 212 form an air inlet gap.

[0031] See also Figures 1 to 10 , the above embodiment given by the present invention further includes that the lower part of the air guide bracket 212 forms an air collecting cover 214, and the centrifugal fan 23 is installed on the top of the air guide bracket 212. The air collecting cover 214 is a downward vertical annular baffle structure, and a plurality of slits are formed on the air collecting cover 214. A circle of retaining rings 217 are provided on the heating bracket 211, and a bent air inlet channel is formed between the retaining ring 217 and the air collecting cover 214. When the external airflow is sucked in, it first bypasses the retaining ring, then hits the air collecting cover 214 to bend, passes through the gap formed by the air collecting cover 214 and the heating bracket 211, enters the interior of the air guide bracket 212, and finally is discharged from the surroundings of the centrifugal fan. In this process, the heating element 22 heats the incoming airflow. The top of the air guide bracket 212 forms an air guide arc surface 215, and the angle of the air guide arc surface 215 is 20 degrees to 40 degrees. In this embodiment, it is 29 degrees. The wind guiding arc surface 215 is conducive to the air discharge, so that the air flow passes more smoothly. The above angle can better discharge the air flow in the horizontal direction.
