The connection between the pipe body 11 and the air inlet joint 12 is the narrowest part of the pipe diameter of the pipe body 11, and when liquid or gas flows in the venturi tube 1, the venturi tube 1 can generate a venturi effect. This effect is manifested in the phenomenon that the flow rate of the fluid increases when the restricted flow passes through a reduced flow cross section, the flow rate being inversely proportional to the flow cross section. While an increase in flow rate is accompanied by a decrease in fluid pressure, as is known from bernoulli's law. Colloquially, this effect is the creation of low pressure in the vicinity of a high velocity flowing fluid, thereby creating an adsorption effect.
The water heater of this embodiment utilizes the venturi effect that venturi 1 produced, in the water route of negative ion module 3 is inhaled to the negative ion that produces to through set up check valve 2 on air inlet 121, prevent that the water in the water route from getting into negative ion module 3. After the negative ions enter the water way, germs in the water can be killed, and the water rich in the negative ions can also have positive effect on the health of human bodies after entering the bathroom.
In actual operation, because of the basic functional characteristics of the check valve 2, the check valve 2 only allows gas to enter the water path through the check valve 2, but does not allow water in the water path to permeate into the air path, thereby ensuring the normal operation of the anion module 3.
As shown in fig. 1, the water heater further comprises a filter screen 4, and the filter screen 4 is arranged on the anion module 3. The filter screen 4 can filter dust or other foreign matters in the air, can avoid the inside of the anion module 3 and corresponding air passages from being blocked, and ensures the normal operation of the anion module 3.

As shown in fig. 1, the water heater of this embodiment further includes a housing 6, the anion module 3 is disposed in the housing 6, an opening (not shown) is disposed on the housing 6, and the filter screen 4 is disposed on the opening. The anion module 3 can suck relatively clean air from the outside of the housing 6 and can not suck air from the inside of the housing 6. When the water heater works, high-temperature flue gas generated by internal combustion contains a small amount of tiny particles, if the negative ion module 3 sucks air from the inside of the shell 6, the service life of the filter screen 4 can be reduced, and the resistance of the negative ion module 3 for sucking air is large, so that the normal operation of the negative ion module 3 is not facilitated. In addition, if filter screen 4 sets up inside shell 6, also be convenient for clean or change filter screen 4, improved the maintenance degree of difficulty of water heater.
As shown in fig. 1 and 3, the water heater of the present embodiment further includes a cover plate 7, the cover plate 7 is disposed on the surface of the outer shell 6, and the cover plate 7 is used for covering the opening on the outer shell 6. When the water heater does not operate for a long time or the anion module 3 does not need to operate, the cover plate 7 can be used for covering the opening on the shell 6, so that foreign matters such as dust in the outside air can be prevented from being attached to the filter screen 4, and the filter screen 4 is kept clean. One side of the sealing cover plate 7 can be hinged with the shell 6, and certain damping is arranged, so that the sealing cover plate 7 can be fixed at various angles with the surface of the shell 6, and opening and closing of the opening can be realized only by turning over the sealing cover plate 7.
When the cover plate 7 covers the opening on the shell 6, the air inlet is closed, the negative ion module 3 stops working, air and negative ions are not additionally injected into the water path, and the normal hot water mode is adopted.

Furthermore, the air suction nozzle of the air pump 8 is connected with the filter screen 4, the air outlet nozzle of the air pump 8 is connected with the anion module 3, and after the air pump 8 is started, on one hand, the air content entering the venturi tube 1 can be increased, so that the content of water is increased, and the oxygen content level in a bathroom is improved; on the other hand, when the low pressure generated by the Venturi tube 1 is weak, the negative ions can be ensured to smoothly enter the water channel.
Further, the water heater of the embodiment further includes a water storage tank 91, and the water storage tank 91 is connected to the water outlet 112 of the venturi tube 1. The water storage tank 91 can buffer water flow and water temperature, and is matched with the anion module 3 and the Venturi tube 1, so that air with anions and water can be fully mixed in the water storage tank 91, and the sterilization effect of the anions on germs is enhanced.

The low pressure generated in the Venturi tube 1 is closely related to the water flow, when the water flow is larger, the Venturi tube 1 can generate enough low pressure to ensure the effective suction of the negative ion air, so that the air pump 8 does not need to be started, and the purposes of energy conservation and consumption reduction are achieved. When the water flow is small, the venturi tube 1 cannot generate enough low pressure to ensure effective suction of the negative ion air, so that the air pump 8 needs to be started to pump the negative ion air into the water path.
The water heater of the embodiment has two different working modes, namely an air oxygenation hot water mode and an ion air purification hot water mode.
In the air oxygenation hot water mode, the anion module 3 stops working, but under the action of the suction force of the Venturi tube 1 or the air pump 8, external air enters the water channel to form bubbles with different degrees, the air and hot water enter the bathroom together, and the oxygen content of the bathroom is increased while bathing.
