[0021] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation on the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] As Figures 1 to 4 shown, this embodiment provides a portable gas water heater, including a box body 1, a battery, a water pipe 2, a gas pipe 3, a control circuit board 4, and a heating box body 5. The control circuit board 4 is installed on the side wall inside the box body 1. The battery is connected to the control circuit board 4, and the battery is used to supply power to each component of the entire gas water heater. A burner 51 is installed at the bottom of the heating box body 5, and the gas pipe 3 is connected to the burner 51. The gas pipe 3 supplies gas into the burner 51 for combustion. A plurality of heating fins 52 are arranged at the top position of the heating box body 5. The heating fins 52 are heated by the burner 51 and then transfer the heat to the water pipe 2. The water pipe 2 includes a water inlet pipe 21, a heating water pipe 22, and a water outlet pipe 23. The water inlet pipe 21, the heating water pipe 22, and the water outlet pipe 23 are connected in communication. The heating water pipe 22 spirals upward along the periphery of the heating box body 5. The burner 51 heats the heating box body 5, transfers the heat to the heating water pipe 22, and passes through and connects the heating fins 52 back and forth. The heating water pipe 22 penetrates the heating fins 52 from left to right, then turns and penetrates from right to left, back and forth several times. The water inlet pipe 21 and the water outlet pipe 23 extend outside the box body 1 for connecting to external water pipes. A water flow sensor 24 is provided on the water inlet pipe 21, and an igniter is provided on the burner 51. The igniter is used to ignite the burner 51. An electromagnetic valve 31 is provided on the gas pipe 3. The control circuit board 4 is respectively connected to the water flow sensor 24, the igniter, and the electromagnetic valve 31. The water flow sensor 24 senses the flow of water and the amount of water passing through. Water enters from the water inlet pipe 21. When the water flow sensor 24 senses the passing of water, it sends a signal to the control circuit board 4. The control circuit board 4 then opens the electromagnetic valve 31 to allow gas to enter the burner 51 from the gas pipe 3. At the same time, the control circuit board 4 activates the igniter. Heat is transferred from the heating box body 5 to the heating fins 52. The heating water pipe 22 absorbs the heat of the heating box body 5 and also receives the heat of the heating fins to heat the water. The hot water is discharged from the water outlet pipe 23. This structure is simple, the overall volume is small, it is convenient to use outdoors, and it can continuously generate hot water.

[0023] Preferably, a smoke hood 53 is provided at the top of the heating box body 5. The smoke hood 53 extends towards the side of the box body 5. An exhaust groove 11 is provided on the box body 1.

The solenoid valve 31 can be opened or closed through the knob switch 311, or the gas volume can be adjusted to control the combustion firepower of the burner 51.

[0025] In the prior art, outdoor water sources are required to heat water. However, in reality, the cleanliness of the water source is difficult to control. Therefore, preferably, a water filtration pump 6 is installed on the water inlet pipe 21 outside the box body 1. During the pumping process, direct filtration is carried out to improve the cleanliness of the water, ensure the smoothness of the water pipes in the gas water heater, and avoid blockage.

The water filtration pump 6 is electrically connected to the power connection terminal 12. The water filtration pump 6 is powered by the battery in the gas water heater, and the water filtration pump 6 can be started by connecting to the power connection terminal 12 nearby, improving convenience.

[0027] Preferably, the end of the gas pipe 3 extends outside the box body 1. The end of the gas pipe 3 is connected to a gas cylinder 7. The gas cylinder 7 is detachable and can share the weight. Gas cylinders 7 with different capacities can be used according to different needs, and the installation is convenient.

[0028] Preferably, a temperature sensor 231 is installed in the water outlet pipe 23. The temperature sensor 231 is electrically connected to the control circuit board 4. The temperature sensor 231 detects the water temperature of the water outlet pipe 23 and feeds the data back to the control circuit board 4 for digital display.

[0029] Preferably, the heating water pipe 22 is welded to the surface of the heating box body 5. The welded position can conduct heat and prevent the separation of the heating box body 5 and the heating water pipe 22 from causing poor heating effect.
