As shown in fig. 1 to 8, the embodiment of the present utility model provides a hydrogen-rich water apparatus capable of increasing the hydrogen content of water for users on the premise of filtering scale generated during electrolysis.

As shown in fig. 1 to 4, the hydrogen rich water apparatus includes a housing 1, an electrolysis structure 2, and a filter assembly 3, wherein the housing 1 forms a receiving chamber for receiving hot water, and the housing 1 has a hot water inlet 112 and a hydrogen rich water outlet 121 communicating with the receiving chamber; the hot water inlet 112 may communicate with a hot water outlet of the water heater, and the hot water of the water heater enters into a receiving chamber formed in the housing 1 to be electrolyzed.

The electrolysis structure 2 is arranged in the accommodating cavity, the electrolysis structure 2 is used for electrolyzing hot water flowing into the shell 1 from the water heater, the electrolysis structure 2 comprises an electrolysis module 21 and an electrode binding post, the electrode binding post is connected with an external electric wire and is used for providing electric energy for the electrolysis module 21, one end of the electrode binding post is connected with the electrolysis module 21, and the other end of the electrode binding post is exposed out of the shell 1 so as to be connected with the external electric wire.

The filter assembly 3 comprises a filter screen 31, baffles 32 and a water outlet pipe 33, wherein the filter screen 31 is surrounded to form a filter cavity, the baffles 32 are arranged at two ends of the filter screen 31 to block the filter cavity, one end of the water outlet pipe 33 penetrates through one baffle 32 to be communicated with the filter cavity, and the other end of the water outlet pipe 33 is communicated with the hydrogen-rich water outlet 121. After the hot water is electrolyzed, the filtered hot water flows out of the shell 1 after being filtered by the filter assembly 3, the filter cavity formed by surrounding the filter screen 31 is communicated with the water outlet pipe 33, so that the water outlet pipe 33 directly takes water from the filter cavity, scale can be prevented from flowing out of the shell 1, and the filter cavity can be formed by surrounding the filter screen 31, so that the whole structure of the hydrogen-rich water device is more compact under the premise of ensuring filtration.

The filter component 3 is arranged above the electrolytic structure 2, and because the filter component 3 is arranged above the electrolytic structure 2, and the hydrogen density is less than that of water, hydrogen generated by electrolysis can be gathered on the upper part of the accommodating cavity formed by the shell 1, the hydrogen ion content on the upper part of the accommodating cavity is higher than that of other positions, hot water can be mixed with more hydrogen ions after being filtered by the filter component 3, hot water mixed with more hydrogen ions flows out of the shell 1 from the water outlet pipe 33 and the hydrogen-rich water outlet 121, and compared with the prior art, the content of the hot water hydrogen ions flowing out of the hydrogen-rich water device provided by the embodiment is higher on the premise of guaranteeing filtration.

Further, with continued reference to fig. 2 and 3, the hot water inlet 112 is disposed below the hydrogen-rich water outlet 121, and the hydrogen-rich water outlet 121 is provided with the water outlet pipe 33. I.e. the hot water inlet 112 is provided at the lower portion of the housing 1, and the hydrogen rich water outlet 121 is provided at the upper portion of the housing 1. Thus, when the hot water rich in a large amount of hydrogen ions flows out of the shell 1, the hot water can not be mixed with the hot water just entering the shell 1, the content of the hydrogen ions in the hot water is ensured, and most of the hydrogen-rich water can be conveniently extruded.

In some embodiments, the hot water inlet 112 and the hydrogen-rich water outlet 121 are disposed on the same side of the housing 1, which may cause dead water in other areas of the housing 1, and for this purpose, the hot water inlet 112 is provided with the water inlet pipe 4, the water inlet pipe 4 extends into the housing 1 from the hot water inlet 112 on one side of the housing 1, and one end of the water inlet pipe 4 extending into the housing 1 is disposed near the other side of the housing 1, so that dead water on the other side of the housing 1 can be avoided, and water fluidity in the housing 1 is ensured. It will be appreciated that the length of the inlet pipe 4 extending into the housing 1 is slightly less than the length of the housing 1.

The top surface of the electrolytic module 21 is not higher than the central axis of the filter assembly 3. Therefore, more hydrogen ions can be ensured to be gathered in the filter cavity, and the content of the hydrogen ions in the hot water flowing out of the hydrogen-rich water device is ensured to be higher.

In some embodiments, in order to further increase the content of hydrogen ions in the hot water flowing out of the hydrogen-rich water device, the housing 1 at least includes an electrolysis portion 11 and a filtration portion 12, the filtration portion 12 is disposed at the top of the electrolysis portion 11 and the electrolysis portion 11 is in communication with the filtration portion 12, the electrolysis structure 2 is disposed at the electrolysis portion 11, the filtration assembly 3 is disposed at the filtration portion 12, and the cross-sectional area of the filtration portion 12 is smaller than the cross-sectional area of the electrolysis portion 11, so that the hydrogen ions are collected in the area enclosed by the filtration portion 12, and the content of hydrogen ions in the hot water per unit area can be further increased.

The electrolytic portion 11 and the filter portion 12 are connected by welding, caulking, screw connection, or the like.

The filter assembly 3 is located above or obliquely above the electrolytic structure 2.

For example, as shown in fig. 5, in the present embodiment, the filter screen 31 includes a plurality of V-shaped filter screen units 311, each V-shaped filter screen unit 311 has two filter plates 3111, first ends of the two filter plates 3111 are connected to form a V-shaped structure, the plurality of V-shaped filter screen units 311 are circumferentially arranged along the central axis of the water outlet pipe 33, openings of the V-shaped filter screen units 311 face the central axis of the water outlet pipe 33, and adjacent V-shaped filter screen units 311 are connected to each other, that is, second ends of the adjacent filter plates 3111 are connected, by providing the plurality of V-shaped filter screen units 311, the filter area of the filter assembly 3 can be increased, and further more hot water can be filtered per unit time.

Of course, in other embodiments, the filter screen 31 has a plurality of filter plates 3111 in the circumferential direction in order to enhance the filtering effect. The filter plates 3111 may be straight plates (flat plate structures) or curved plates (i.e., arc structures), and each filter plate 3111 may have the same length, so that the baffle 32 may be conveniently connected to the filter screen 31, but the width may be limited according to actual needs, so long as the contact area between the filter assembly 3 and hot water can be increased.

Of course, in other embodiments, as shown in FIG. 6, the cross-section of the screen 31 is polygonal. The filter screen 31 of polygonal structure can also increase the filtering area of the filter assembly 3. More specifically, the cross section of the screen 31 is a regular polygon. So that the hot water can uniformly enter the filter chamber from all the positions of the filter screen 31.

Of course, in other embodiments, as shown in fig. 7, the filter screen 31 may be spirally wound, and the free end of the filter screen 31 is closely connected to the side wall of the filter screen 31, so that hot water is prevented from flowing out of the hydrogen-rich water outlet 121 from the space formed by winding the filter screen 31 without being filtered. The free end of the filter screen 31 is connected with the side wall of the filter screen 31 in a sealing manner, specifically, the free end of the filter screen 31 is welded with the side wall of the filter screen 31, or the filter screen 31 is connected with the side wall of the filter screen through other structures, so long as the filter chamber enclosed by the filter screen 31 can be sealed, and the filter screen 31 can filter hot water in a protection range when the hot water enters the filter chamber.

It is understood that the filter screen 31 may be of a unitary structure or of a split structure.
