Abstract

An electromagnetic induction heater, including: a first cover plate; an inductive coil; a housing; a glass pipe; a second cover plate; a first control plate; a second control plate; a power button; a first baffle plate; a pair of electrodes; a third cover plate; a battery; a support frame; a battery connector; a spring; and a second baffle plate. The pair of electrodes is disposed on the support frame. The first baffle plate is disposed on the pair of electrodes and is fixed on the support frame. The spring butts against the battery connector. The spring and the battery connector are disposed in one end of the support frame. The second baffle plate is directly connected to the spring and fixed on the one end of the support frame. The support frame is disposed in the housing. The inductive coil is disposed on the first control plate.

First claim

What is claimed is:

1) first cover plate;
2) an inductive coil;
3) a housing;
4) a glass pipe;
5) a second cover plate comprising a through hole;
6) a first control plate;
7) a second control plate;
8) a power button;
9) a first baffle plate;
10) a pair of cup-shaped electrodes;
11) a third cover plate;
12) a battery;
13) a support frame;
14) a battery connector;
15) a spring; and
16) a second baffle plate;
wherein:
the pair of cup-shaped electrodes is disposed on the support frame;
the first baffle plate is disposed on the pair of cup-shaped electrodes and is fixed on the support frame;
the spring butts against the battery connector; the spring and the battery connector are disposed in one end of the support frame; the second baffle plate is directly connected to the spring and fixed on the one end of the support frame; the support frame is disposed in the housing;
the inductive coil is disposed on the first control plate; the first control plate is disposed on the second control plate; the inductive coil, the first control plate, and the second control plate are disposed in the housing;
the second control plate comprises positive and negative electrodes connected to the pair of cup-shaped electrodes; the glass pipe is disposed in the inductive coil; the glass pipe is empty for accommodating a metal carrier and comprises a pipe end that is open and that is connected to the through hole of the second cover plate; the battery is disposed in the support frame; and
the power button is disposed on the second cover plate; the first cover plate is disposed on one end of the housing; the second cover plate is disposed on the housing to cover the inductive coil, and the third cover plate is disposed on the housing to cover the battery.
