Example one

As shown in fig. 1 and fig. 2, the water heater of an embodiment includes a venturi tube 1, a check valve 2 and an anion module 3, the venturi tube 1 is disposed on a water path of the water heater, the venturi tube 1 includes a tube body 11 and an air inlet connector 12, two ends of the tube body 11 are respectively provided with a water inlet 111 and a water outlet 112, the air inlet connector 12 is disposed on a tube wall of the tube body 11, one end of the air inlet connector 12 away from the tube body 11 is provided with an air inlet 121, the anion module 3 is provided with an air inlet and an air outlet, the air outlet is communicated with the air inlet 121, the check valve 2 is disposed on the air inlet 121, of course, in a certain embodiment, the check valve 2 may also be disposed on the air outlet.

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.

Further, the anion module 3 includes an anion generator 31 and a mounting box 32, the anion generator 31 is disposed in the mounting box 32, the mounting box 32 is provided with an air inlet (not shown) and an air outlet (not shown), the filter screen 4 is disposed on the air inlet, and the air outlet is connected to the check valve 2. The negative ions generated by the negative ion generator 31 can be confined in the mounting box 32 and cannot escape, and since the venturi tube 1 can generate low pressure at the air inlet 121, the negative ions in the mounting box 32 are subsequently sucked into the venturi tube 1 from the air outlet, so that the directional flow of the negative ions is realized.

The water heater of this embodiment still includes connecting pipe 5, and the one end of connecting pipe 5 is connected with the air outlet of mounting box 32, and the other end and the check valve 2 of connecting pipe 5 are connected. The connecting pipe 5 may be a hard pipe or a flexible pipe, and the flexible pipe includes a rubber hose or a flexible metal pipe, etc. The connecting pipe 5 of this embodiment is the rubber tube preferably, has convenient nimble advantage, and in the installation of reality, the length of connecting pipe 5 is tailor according to the distance of mounting box 32 and check valve 2, avoids connecting pipe 5 to take place excessive buckling or curling, guarantees that connecting pipe 5 is inside unblocked.

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.

Example two

As shown in fig. 4, the water heater of this embodiment further includes an air pump 8, the air pump 8 includes an air pumping nozzle and an air outlet nozzle, an air pumping port is provided on the air pumping nozzle, an air outlet is provided on the air outlet nozzle, the air pumping port and the opening of the air pump 8 are communicated, the air outlet and the air inlet of the air pump 8 are communicated, the external air enters the air pump 8 from the air pumping port of the air pump 8 after passing through the filter of the filter screen 4, and the air intake efficiency of the venturi tube 1 is improved by the pump pressure of the air pump 8. 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 water heater of the embodiment further comprises a heat exchanger 92, a cold water pipe 93 and a hot water pipe 94, wherein the water inlet 111 of the venturi tube 1 is connected with the outlet of the heat exchanger 92, and the cold water pipe 93 is connected with the inlet of the heat exchanger 92. Since the water outlet 112 of the venturi tube 1 is connected to the water storage tank 91 and the water inlet 111 of the venturi tube 1 is connected to the outlet of the heat exchanger 92, the water storage tank 91 is used for temporarily storing hot water, thereby playing a role of buffering the water temperature.

Further, a water flow sensor 95 is disposed on the cold water pipe 93, and the water heater further includes a controller (not shown in the figure), wherein the controller is electrically connected to the water flow sensor 95 and the air pump 8, respectively. In practical application, the water flow sensor 95 transmits the detected signal to the controller, the controller executes the operation of the air pump 8 according to the signal, and when the water flow detected by the water flow sensor 95 is less than or equal to a set value, the air pump 8 works; when the water flow rate detected by the water flow rate sensor 95 is greater than the set value, the air pump 8 stops operating. 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.

Under anion air purification hot water mode, when water flow sensor 95 sends actuating signal, water heater start-up work, anion module 3 also starts the operation simultaneously, produces the anion, under venturi 1's suction or the effect of air pump 8, with anion air suction water route, form not equidimension bubble in aquatic, along with rivers entering bathroom, increase the anion content in the bathroom, improve the bathing environment greatly, be close the bathing of nature oxygen boosting environment, make the human body healthier.

In the detailed description of the embodiments, various technical features may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
