The gas water heater is installed upright on the ground or under a cabinet. This invention proposes a completely new form of gas water heater, breaking away from the current situation where gas water heaters are wall-mounted or protrude from the wall. This is achieved through the design of a completely new shell shape, inlet and outlet water pipes, proportional valve pipes, and fume hood top cylinder, among other structural features.

[0004] For example, patent document CN119146580A discloses a gas water heater and its control method. The gas water heater includes: a water supply pipeline; a burner for heating the water supply pipeline; a gas pipeline for supplying gas to the burner, wherein a gas proportional valve and the burner are connected in series along the airflow direction on the gas pipeline; and a controller for: responding to user operation, controlling a booster pump to pressurize the water flow in the water supply pipeline at a first head.

[0005] However, in the above technology, the gas enters the burner directly after passing through the proportional valve, resulting in uneven gas discharge and affecting combustion efficiency.

[0006] Therefore, a portable water heater is proposed to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a portable water heater in which the gas passing through the proportional valve flows to the burner through the gas distribution pipe, which has the advantages of uniform gas distribution and high combustion efficiency.

[0009] As a further improvement to the above technical solution, the bend and the connecting pipe, as well as the connecting pipe and the proportional valve, are connected by bolts.

[0010] As a further improvement to the above technical solution, it also includes two clamps, multiple pipes located between the two clamps, multiple fire outlets at the top of the pipes, inserts on the sides of the pipes, and notches on the clamps, with the inserts inserted into the notches.

[0011] As a further improvement to the above technical solution, both ends of the burner and the gas distribution pipe are provided with fixing plates, and the fixing plates are fixedly connected to the clamping plate and the gas distribution pipe by bolts.

[0012] As a further improvement to the above technical solution, the fixing plate is provided with a bracket, which is fixedly connected to the housing.

[0013] As a further improvement to the above technical solution, one side of the housing is an opening, and a panel is provided at the opening of the housing.

[0014] As a further improvement to the above technical solution, a base is also included, and the housing is movably inserted into the base.

[0015] As a further improvement to the above technical solution, a water flow sensor is provided at the water inlet end of the heat exchange tube, and a temperature sensor is provided at the water outlet end of the heat exchange tube.

[0016] The beneficial effects of this utility model are: by setting up a gas distribution pipe, the gas passing through the proportional valve flows to the burner through the gas distribution pipe, which has the advantages of uniform gas distribution and high combustion efficiency.
