[0002] As people's quality of life improves, more and more people are keen on outdoor camping, but there has always been a problem with hot water supply in outdoor camping. It is impossible to enjoy hot water at any time outdoors like indoors. For this reason, portable water heaters have appeared on the market, which can be convenient for people to carry with them and enjoy hot water supply outdoors.

[0003] For example, the patent with announcement number CN220206082U discloses an outdoor gas water heater powered by dry batteries, including a box body and a burner and a heat exchanger arranged in the box body. A dry battery pack is arranged in the box body, and the dry battery pack is electrically connected to at least an ignition device in the burner; the box body is also provided with an electrical port and a power supply port, and the electrical port is electrically connected to the power supply port; the electrical port is used to input an external power supply, and the power supply port is used to power an external water pump.

[0004] The problem with the above-mentioned water heater is that the water heater transports cold water into the tank through an external water pump and heats the cold water through a heat exchanger. When the gas supply is insufficient, the amount of cold water transported by the water pump is fixed and the heating efficiency of the burner is reduced, and the cold water cannot be heated to the specified temperature required by the user, which greatly reduces the customer's usage experience.

[0005] Therefore, a constant temperature portable water heater is proposed to solve the above problems. Utility Model Content

[0006] In order to solve the above technical problems, the purpose of the utility model is to provide a constant temperature portable water heater, which can adjust the water output according to the water temperature.

[0007] The utility model adopts the following technical scheme to solve the problem: a constant temperature portable water heater, comprising a box body, wherein a burner and a heat exchanger are arranged in the box body, wherein the heat exchanger is arranged on the top of the burner, and wherein the burner is used to heat the heat exchanger; wherein a water inlet pipe and a water outlet pipe are also arranged in the box body, wherein the water inlet pipe is connected to the water inlet end of the heat exchanger, wherein the water outlet pipe is connected to the water outlet end of the heat exchanger, wherein a water volume regulating valve is arranged on the water outlet pipe, wherein probes are arranged at the ends of the water inlet pipe and the water outlet pipe, and wherein the probes are connected to the water volume regulating valve signal.

[0008] As a further improvement of the above technical solution, it also includes a fan, which is arranged beside the burner, the air inlet of the fan is connected to the outside, and the air outlet of the fan is connected to the inside of the burner.

[0009] As a further improvement of the above technical solution, it also includes a gas tank and a gas supply pipe, the gas supply pipe is arranged in the box body, the gas outlet end of the gas supply pipe is connected to the gas inlet end of the burner, the gas inlet end of the gas supply pipe is arranged on the outside of the box body, and the gas tank is detachably connected to the gas inlet end of the gas supply pipe.

[0010] As a further improvement of the above technical solution, the water inlet pipe is spirally coiled on the outside of the heat exchanger.

[0011] As a further improvement of the above technical solution, an exhaust port is provided on the top of the heat exchanger, a heat dissipation hole is provided on the side end of the box body, and an air collecting hood connecting the exhaust port and the heat dissipation hole is provided on the top of the heat exchanger.

[0012] The beneficial effects of the utility model are as follows: water flows into the heat exchanger through the water inlet pipe to be heated, and then is discharged outward through the water outlet pipe. When the gas supply is insufficient, the heating efficiency of the burner will be reduced, so that the water temperature cannot reach the temperature specified by the user. At this time, a signal can be transmitted to the water flow regulating valve through the probe to reduce the water flow rate, thereby improving the heating efficiency of the water flow to reach the temperature specified by the user, giving the user a better experience.
