[0004] Although the above-mentioned heating device is convenient to carry, the waste gas generated by combustion is directly discharged in the room, and the safety is insufficient. UTILITY MODEL CONTENT

[0005] In order to make up for the deficiencies in the prior art, the utility model provides a high safety gas heating device, which adopts the following technical scheme:

[0006] A high safety gas heating device, comprising a shell, a combustion chamber and a heat exchange chamber are arranged in the shell, a burner is arranged in the combustion chamber, an air inlet pipe is connected to the inlet of the combustion chamber, and the outlet of the combustion chamber is connected to the inlet of the heat exchange chamber; the outlet of the heat exchange chamber is connected to a flue gas discharge pipe, the shell is installed in a room, and the air inlet pipe and the flue gas discharge pipe are arranged outside the room.

[0007] Further, the air inlet pipe is sleeved in the flue gas discharge pipe, and the length of the air inlet pipe is greater than the length of the flue gas discharge pipe.

[0008] Further, the burner is connected with an ODS protection device.

[0009] Further, the burner is connected with a piezoelectric igniter and a gas control valve, and a control knob is arranged on the shell.

[0010] Further, the shell is composed of a front shell and a back plate, a plurality of heat dissipation holes are arranged on the front shell

[0011] Compared with the prior art, the gas heating device has the following beneficial technical effects:

[0012] The air required by the combustor during combustion is sucked from the air inlet of the outdoor air inlet pipe, and the exhaust gas generated by the combustor is discharged from the flue gas outlet of the flue gas discharge pipe, so that harm to indoor personnel is avoided, and the purpose of safe use is achieved.

[0017] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a variety of ways beyond the specific details set forth herein without departing from the scope of the present application, and it is understood that the present application is not limited in this respect.

[0018] Example 1

[0019] As shown in Figure 1 , 2 A high-safety gas heating device, comprising a shell composed of a front shell 1 and a back plate 2. A combustion chamber 3 and a heat exchange chamber 4 are provided in the shell, both of which are L-shaped boxes and are respectively provided with an inlet and an outlet. A combustor 5 is provided in the combustion chamber 3, and the inlet of the combustion chamber 3 is connected to an air inlet pipe 6, and the outlet is connected to the inlet of the heat exchange chamber 4.

[0020] The outlet of the heat exchange chamber 4 is connected to a flue gas discharge pipe 7. The air inlet pipe 6 is sleeved in the flue gas discharge pipe 7, so that the overall structure is more compact, and only one hole needs to be opened in the wall during installation; the length of the air inlet pipe 6 is greater than the length of the flue gas discharge pipe 7, and the protruding design can avoid the discharged flue gas from entering the combustion chamber 3 again through the air inlet pipe 6.

[0021] The burner 5 is connected with an ODS protection device 8, a piezoelectric igniter 9 and a gas control valve 10. The piezoelectric igniter 9, the gas control valve 10 and a control knob 11 are arranged on the front shell 1. A plurality of heat dissipation holes are arranged on the front shell 1.

[0022] As shown in Figure 3 the utility model discloses a high safety gas warmer, the shell is installed on the wall 12 of indoor, and the flue gas exhaust pipe 7 is worn through the room outside through the opening of wall. When using, the heat of burner 5 is conducted to the room through its own and heat exchange chamber 4 and reaches the purpose of heating. The air required when burner 5 burns is inhaled from the air inlet of outdoor air inlet pipe 6, and the exhaust gas generated by burner 5 is discharged from the flue gas outlet of flue gas exhaust pipe 7, which will not cause harm to the indoor personnel, and the purpose of safe use is achieved. In addition, the ODS protection device can disconnect the gas passage of the gas control valve 10 when the burner 5 is extinguished or the CO concentration is detected to exceed the set value, so as to achieve the effect of safety protection.

[0023] The above is only the preferred embodiment of the utility model, and is not used for limiting the utility model, although the utility model is described in detail with reference to the embodiment, for the person skilled in the art, still can modify the technical scheme recorded in each preceding embodiment, or equivalent replacement to part technical feature, but any modification, equivalent replacement, improvement etc. within the spirit and principle of the utility model, should be included in the protection scope of the utility model.
