Description

Technical Field

[0001] The utility model relates to the technical field of gas distribution rods, in particular to a multi-segment combined gas distribution rod. Background Art

[0002] With the popularity of gas water heaters and gas stoves, burners used in gas water heaters and gas stoves have also become popular. As the core component of the burner, the gas distributor rod plays a vital role. The gas distributor rod assembly has an air inlet channel and a number of air outlets connected to the air inlet channel. A valve body is provided on the gas distributor rod assembly, through which the on-off of the air inlet channel or the opening and closing of the air outlet can be controlled, thereby controlling the outflow of gas, so as to supply different flow rates of gas in different heating stages of the water heater. When the water temperature is about to rise to the preset temperature, and in the constant temperature stage of the water heater, generally only part of the air outlet is required to flow out the gas, reducing the flow of the gas, so as to heat slowly and prevent the water temperature from deviating too much from the preset temperature.

[0003] The water temperature regulation of gas water heaters is mainly achieved by controlling the number of working combustion heads. The combustion temperature is regulated and controlled by combining different numbers of combustion heads. The number of combinations of combustion heads determines the accuracy of temperature control. The more combinations there are, the more accurate the control of gas outflow and the more precise the temperature control. In order to achieve more combinations, a plurality of valve body assemblies need to be provided on the upper part of a traditional gas distributor rod. The structure is complex and has a large structural volume. Due to the limitation of the structural volume, the traditional gas distributor rod has fewer combustion combinations. Due to the limitation of the combination method, the water temperature regulation of the gas water heater is prone to cause large changes in water temperature, and the water temperature regulation accuracy and stability are poor. Therefore, a multi-segment combined gas distributor rod is proposed. Utility Model Content
