Concealed type connecting structure of warm air blower shell

Abstract

The invention relates to a concealed type connecting structure of a warm air blower shell, comprising the warm air blower shell 10. The concealed type connecting structure of the warm air blower shell is characterized in that protection covers 20 are respectively arranged at the let side and the right side of the warm air blower shell 10, and the protection covers 20 are buckled with the warm air blower shell 10 through buckling type structures; each buckling type structure comprises a first buckling hook 311, a second buckling hook 312, a first buckling groove 321 and a second buckling groove 322, wherein the first buckling hook 311 and the second buckling hook 312 are arranged on the protection covers 20; the first buckling groove 321 and the second buckling groove 322 are arranged on the warm air blower shell 10; the first buckling hook 311 and the second buckling hook 312 are respectively buckled with the first buckling groove 321 and the second buckling groove 322; and the second buckling groove 322 is designed in a non-detachable way. In the invention, the protection covers 20 cover the combining parts and the connecting parts among side plates of the warm air blower shell 10, thereby solving the problem that assembled screws of the warm air blower shell 10 are easy to detach due to exposure; and in addition, the invention has the characteristics of simple structure, easy processing, low production cost, beautiful appearance, and the like.

Description

【Technical field】 [0001] The invention relates to a heater used for air heating, in particular to a hidden connection structure for preventing random disassembly of the heater shell. 【Background technique】 [0002] The heater is generally composed of a shell and circuit components such as a heating device, an air supply device, and a control circuit placed in the shell, and the shell of the heater is usually composed of a top cover, a bottom plate and a side plate. The casing of the traditional heater and the circuit components in the casing are connected by screws. The defect of this connection method is that the screws used to fix the casing are exposed, making it easy for ordinary users to disassemble the casing. If the internal circuit is not familiar, blind disassembly of the shell may cause safety problems due to contact with the conductive components inside the shell. For this reason, someone designed a screw with a special shape to lock and match the shell, so as to...

AI Technical Summary

Problems solved by technology

But in fact, because the special screw is exposed, when users are not familiar with the assembly structure, they will mistakenly think that the screw is an ordinary detachable screw and disassemble the shell, and finally cannot disassemble or dismantle the product

Therefore, the effect of using special screws for safety precautions is not ideal
