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...

Embodiment Construction

[0020] The following examples are further explanations and supplements to the present invention, and do not constitute any limitation to the present invention.

[0021] The hidden connection structure of the heater shell of the present invention is applicable to various types of heaters.

[0022] The concealed connection structure of the heater shell of the present invention includes a shell 10 , two protective covers 20 and a snap-fit ​​structure connecting the protective cover 20 and the shell 10 .

[0023] Such as Figure 1 ~ Figure 3 As shown, the housing 10 is a closed shell made of metal material. The casing 10 is composed of a top cover 11, a bottom plate 12, a front side plate 13, a rear side plate, a left side plate 14, and a right side plate 15. The left side plate 14 includes a left inner plate 141 and a left outer plate 142. The right side panel 15 includes a right inner panel 151 and a right outer panel 152 . The top cover 11 is arranged on the top of the housi...
