A portable gas heater

Abstract

The invention provides a portable gas heater and belongs to the technical field of heaters. According to the portable gas heater, the technical problems that an existing heater is inconvenient and unstable for use and is unsafe in the use process are solved. The portable gas heater comprises a casing, a control valve, a hypoxia protection device and a burner, wherein a gas inlet pipe is connected onto the control valve; a gas outlet pipe is connected between the control valve and the burner; the gas inlet pipe and the gas outlet pipe are communicated to form a burning gas circuit; an ignition gas pipe is connected onto the control valve; a gas outlet end of the ignition gas pipe is opposite to a gas outlet end of the burner; the gas inlet pipe and the ignition gas pipe are communicated to form an ignition gas circuit; a valve core by which the burning gas circuit can stop gas supply during gas supply of the ignition gas circuit is arranged in the control valve; an electromagnetic valve which is connected with the hypoxia protection device and can break off gas inlet of the gas inlet pipe is arranged in the control valve; the ignition gas circuit and the burning gas circuit are separately operated; under the condition that the ignition gas circuit ignites, the ignition success rate of the burning gas circuit is high, the burning gas circuit is stable in flow and is safer in the ignition process.

Description

technical field [0001] The invention belongs to the technical field of heaters, and relates to a portable gas heater. Background technique [0002] A heater is a device used for heating. There are many types of heaters, the most common is the electric heater, which uses electricity as energy for heating and heating, and is mostly suitable for indoor use. There is also a gas heater, which uses gas as energy for heating and heating, and is mostly suitable for some wireless The place where the power supply is provided. [0003] For example, the utility model with the authorized announcement number CN 202209724U discloses a portable gas heater, which includes a housing, a gas burner, a gas supply assembly, a gas cylinder and its fixing assembly, and the housing includes a front panel, a door, and a side panel. , top plate and bottom plate, the gas burner is installed on the front plate of the housing through screws, the container assembly includes a gas safety valve with a kno...

Problems solved by technology

[0003] For example, the utility model with the authorized announcement number CN 202209724U discloses a portable gas heater, which includes a housing, a gas burner, a gas supply assembly, a gas cylinder and its fixing assembly, and the housing includes a front panel, a door, and a side panel. , top plate and bottom plate, the gas burner is installed on the front plate of the housing through screws, the container assembly includes a gas safety valve with a knob and a connecting air pipe, and the gas supply assembly is arranged between the gas burner and the gas cylinder The gas circuit is formed between the gas heaters, the gas cylinder is set in the shell and fixed on the bottom plate, and the oxygen deficiency / flame out protection device ODS is installed on the gas circuit. Although this gas heater has a simple structure and is easy to assemble, it also has the following problems: 1. , It has only one gas path, and the gas supply and ignition are carried out at the same time. The gas flow during ignition is usually determined by the rotation angle of the rotating shaft, and for different people, the rotation angle is different, so it is impossible to control it well. If the rotation angle is too large, the gas flow rate will be large, and the fire will be larger immediately after the ignition is successful, which poses a greater threat to personal safety; 2. Because the ODS blocks the The intake pipe of the permanent flame is fed into the air. After the intake pipe is blocked, there is still gas between the intake pipe and the safety valve. When the ignition is re-ignited, the follow-up gas will be ejected together with this part of the residual gas, which will cause an instant fire. Larger, there are also security risks
