[0054] The gas water heater is a water heater that uses gas as the main energy material, and transfers the high-temperature heat generated by gas combustion to cold water flowing through the heat exchanger to achieve the purpose of preparing hot water.

[0055] Gas water heaters typically include an outer casing, as well as components such as a burner, heat exchanger, fan, and shroud housed within the casing.

[0056] In this process, the gas is delivered to the burner, where it is ignited by an ignition device, so that the burner can burn the delivered gas and generate heat.

[0057] The heat exchanger is equipped with heat exchange tubes. One end of the heat exchange tubes is connected to the water supply pipe, and the other end of the heat exchange tubes is connected to a shower head or faucet.

[0058] The heat generated by the burner burning the gas is used to heat the heat exchange tubes, thereby raising the temperature of the water inside the heat exchange tubes to form hot water.

[0059] When a gas water heater is working, cold water supplied by the water supply pipe flows into the heat exchange tube, and is then heated into hot water by the heat source generated by the burner. The hot water then flows out from the shower head or faucet through the hot water valve for the user's use.

[0060] At the same time, when the gas water heater is working, the fan is powered on and running simultaneously. Under the action of the fan, the flue gas generated by the burner is discharged outdoors.

[0071] Specifically, the filter element 31 is made of polyethylene material as a skeleton material, and the filter material is combined with the skeleton material by a sintering method.

[0072] For example, the filter material includes one or a combination of several of a fof scale inhibitor, calcium sulfite, an antibacterial agent, and a corrosion inhibitor.

[0073] The corrosion inhibitor can form a stable and dense protective film on the surface of the stainless steel heat exchanger after the water passes through, so as to protect the stainless steel heat exchanger.

[0099] The spring elastically abuts between the valve flap and the valve seat, and when there is no water pressure on the one-way valve 33, the spring keeps the one-way valve 33 in the closed position, and when there is water pressure, the valve flap moves under the action of water pressure, allowing water to enter the one-way valve 33.

[0100] When the water pressure of the water purifying device is lower than the opening pressure of the one-way valve 33, i.e. the one-way valve 33 is in the closed state, raw water enters the raw water channel 11 through the raw water inlet head 21, penetrates into the purified water channel 311 through the filter 3121, and the scale inhibitor molecules are released into the water by the core 32 in the purified water channel 311, and the purified water flows into the purified water outlet head 22 through the purified water channel 311.

[0101] When the water pressure of the water purifying device is higher than the opening pressure of the one-way valve 33, i.e. the one-way valve 33 is in the open state, raw water enters the raw water channel 11 through the raw water inlet head 21, penetrates into the purified water channel 311 through the filter 3121, and the scale inhibitor molecules are released into the water by the core 32 in the purified water channel 311, and the purified water flows into the purified water outlet head 22 through the purified water channel 311.

[0102] It should be noted that when the filter 31 is blocked, raw water enters the raw water channel 11 through the raw water inlet head 21, penetrates into the purified water channel 311 through the filter 3121, and mainly enters the purified water channel 311 through the water gap 34.

[0103] In order to facilitate the core 32 to replace the scale inhibitor, the core 32 comprises a main body part 322 and a plug 323, the main body part 322 is downwardly open, and the plug 323 is arranged at the opening end of the main body part 322 and is used for plugging the main body part 322 to avoid the scale inhibitor from falling out. The side wall and the top of the main body part 322 are provided with notches, which facilitates the core 32 to release the scale inhibitor molecules into the water.

[0104] In a second aspect, the embodiments of the present disclosure provide a gas water heater, comprising the water purifying device according to any one of the embodiments of the first aspect. Thus, all the beneficial effects are achieved, which will not be described here.

[0105] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "illustrative embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily mean the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0106] The above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, for those skilled in the art, the technical solutions recorded in the foregoing examples can still be modified, or some of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions claimed by the present application.
