[0037] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0038] See also Figure 1-Figure 4 , shows a hydrogen mixing device in a preferred embodiment of the present invention, comprising:

[0039] A hydrogen mixing pump 1, the water inlet of the hydrogen mixing pump 1 is used to connect the water outlet of the purification device and the hydrogen outlet of the hydrogen production device 10, and the hydrogen mixing pump 1 is used to mix the purified water output by the purification device and the hydrogen output by the hydrogen production device 10 to form hydrogen-rich water;

[0040] The hydrogen mixer 2 has a hydrogen mixing chamber 211, the water inlet of the hydrogen mixing chamber 211 is connected to the water outlet of the hydrogen mixing pump 1, and the water outlet of the hydrogen mixing chamber 211 is used to connect to the water outlet device. The hydrogen mixing chamber 211 is used to mix the hydrogen in the hydrogen-rich water output by the hydrogen mixing pump 1 and the purified water under the pressure of the hydrogen mixing pump 1; and

[0041] The first water shutoff device 3 is provided in the hydrogen mixing chamber 211 or in the water outlet of the hydrogen mixing chamber 211. The first water shutoff device 3 has a first water passage 31. The first water passage 31 is used to connect the hydrogen mixing chamber 211 and the water outlet device. The cross-sectional area of ​​the first water passage 31 is smaller than the cross-sectional area of ​​the hydrogen mixing chamber 211.

[0042] The hydrogen mixing device of the present invention includes a hydrogen mixing pump 1, a hydrogen mixer 2 and a first water shutoff 3. During hydrogen mixing, the purified water output by the purification device and the hydrogen output by the hydrogen production device 10 are initially mixed under the pumping of the hydrogen mixing pump 1 to form hydrogen-rich water. Then, the hydrogen-rich water is transported to the hydrogen mixer 2. Under the action of the hydrogen mixing pump 1, the hydrogen-rich water in the hydrogen mixing chamber 211 rolls under the pressure of the hydrogen mixing pump 1, so that the water and hydrogen in the hydrogen-rich water are mixed more evenly and fully, thereby increasing the hydrogen content in the hydrogen-rich water. content, wherein, since the first water shutoff device 3 is arranged in the hydrogen mixing chamber 211 or in the water outlet of the hydrogen mixing chamber 211, the first water shutoff device 3 has a first water passage 31, and the first water passage 31 is used to connect the hydrogen mixing chamber 211 and the water outlet device. The cross-sectional area of ​​the first water passage 31 is smaller than the cross-sectional area of ​​the hydrogen mixing chamber 211, which can reduce the water outlet flow rate and increase the pressure holding time, so that the purified water and hydrogen in the hydrogen-rich water are mixed more evenly and fully, so as to obtain hydrogen-rich water with a higher hydrogen concentration.

[0043] See also Figure 3 In one embodiment, the number of the first water passage 31 is one, so as to reduce the water outlet flow rate, increase the pressure holding time, and make the purified water and hydrogen in the hydrogen-rich water mix more evenly and fully, so as to obtain hydrogen-rich water with a higher hydrogen concentration. At the same time, the overall structure of the first water shutoff device 3 with only one first water passage 31 is simpler, which is conducive to reducing the preparation cost of the first water shutoff device 3.

[0044] Of course, in other embodiments, there may be multiple first water passages 31 , and the sum of the total cross-sectional areas of the multiple first water passages 31 is smaller than the cross-sectional area of ​​the hydrogen mixing chamber 211 .

[0045] In one embodiment, the first water shutoff device 3 is clamped in the hydrogen mixing chamber 211 to achieve reliable fixation of the first water shutoff device 3 in the hydrogen mixer 2, thereby achieving connector-free installation of the first water shutoff device 3, making installation more convenient and reducing the use of connectors, thereby reducing costs.

[0046] Of course, in other embodiments, the first water shutoff device 3 may be clamped in the water outlet of the hydrogen mixing chamber 211 , or the first water shutoff device 3 may be fixedly connected to the hydrogen mixer 2 via a connector.

[0047] In one embodiment, the hydrogen mixing device further comprises:

[0048] The second water shutoff device 4 is located at the water inlet of the hydrogen mixing chamber 211. The second water shutoff device 4 has a second water passage 41, which connects the water outlet of the hydrogen mixing pump 1 and the hydrogen mixing chamber 211. The cross-sectional area of ​​the second water passage 41 is smaller than that of the hydrogen mixing chamber 211. Because the cross-sectional area of ​​the second water passage 41 is smaller than that of the hydrogen mixing chamber 211, it can prevent water in the hydrogen mixing chamber 211 from flowing back from the water inlet of the hydrogen mixing chamber 211 to the hydrogen mixing pump 1, thereby ensuring that the purified water and hydrogen in the hydrogen mixing chamber 211 are fully mixed, thereby obtaining hydrogen-rich water with a higher hydrogen concentration.

[0049] To facilitate the installation of the second water shutoff device 4, in one embodiment, the second water shutoff device 4 is clamped in the water inlet of the hydrogen mixing chamber 211 to ensure that the second water shutoff device 4 is reliably fixed in the hydrogen mixer 2, thereby realizing the installation of the second water shutoff device 4 without connectors, making the installation more convenient, reducing the use of connectors, and reducing costs.

[0050] See also Figure 4 In one embodiment, the outer wall of the second water shutoff device 4 has multiple second water passages 41 spaced apart around the axial centerline of the second water shutoff device 4 . The total cross-sectional area of ​​the multiple second water passages 41 is less than the cross-sectional area of ​​the hydrogen mixing chamber 211 . Because there are multiple second water passages 41, the multiple second water passages 41 can divert the hydrogen-rich water as it is transported from the hydrogen mixing pump 1 to the hydrogen mixing chamber 211 through the multiple second water passages 41, facilitating more uniform mixing of water and hydrogen in the hydrogen-rich water, thereby further increasing the hydrogen content in the hydrogen-rich water.

[0051] In one embodiment, the hydrogen mixer 2 comprises:

[0052] A hydrogen mixing body 21, the hydrogen mixing body 21 having a hydrogen mixing chamber 211 and an installation port. The water inlet of the hydrogen mixing chamber 211 is located at a first end in the length direction of the hydrogen mixing chamber 21, and the water outlet of the hydrogen mixing chamber 211 is located at a second end in the length direction of the hydrogen mixing chamber 21. The installation port is located on a side close to the water inlet of the hydrogen mixing chamber 211, and the installation port is farther away from the water outlet of the hydrogen mixing chamber 211 than the water inlet of the hydrogen mixing chamber 211. The installation port is connected to the water inlet of the hydrogen mixing chamber 211, and the installation port can allow the second water shutoff device 4 to enter and exit the water inlet of the hydrogen mixing chamber 211. The water outlet of the hydrogen mixing chamber 211 can allow the first water shutoff device 3 to enter and exit the hydrogen mixing chamber 211.

[0053] The water inlet connector 22 is located on the side of the hydrogen mixing body 21. The water inlet of the water inlet connector 22 is connected to the water outlet of the hydrogen mixing pump 1, and the water outlet of the water inlet connector 22 is connected to the water inlet of the hydrogen mixing chamber 211.

[0054] a water plug 23, which is adapted to the installation opening to seal the installation opening; and

[0055] The water outlet connector 24 is provided on the water outlet of the hydrogen mixing chamber 211 , and the water inlet of the water outlet connector 24 is used to connect the hydrogen mixing chamber 211 and the water outlet device. In this way, during installation, the first water shutoff device 3 can be first pushed into the hydrogen mixing chamber 211 through the water outlet of the hydrogen mixing pump 1, and then the water outlet joint 24 can be installed. The water outlet joint 24 can be used to limit the first water shutoff device 3 from being separated from the hydrogen mixing chamber 211. At the same time, the water outlet joint 24 can be used to connect the hydrogen mixing chamber 211 and the water outlet device. Then, the second water shutoff device 4 is pushed into the water inlet of the hydrogen mixing pump 1 through the installation port, and then the water plug 23 is installed. The water plug 23 can be used to limit the second water shutoff device 4 from being separated from the water inlet of the hydrogen mixing chamber 211, thereby further improving the assembly stability of the second water shutoff device 4. At the same time, the setting of the water plug 23 can limit the outflow of water in the hydrogen mixing chamber 211. This hydrogen mixer 2 can greatly reduce the installation difficulty of the first water shutoff device 3 and the second water shutoff device 4, making the installation more convenient.

[0056] In one embodiment, the water inlet connector 22 is perpendicular to the hydrogen mixing body 21 to reduce the difficulty of installing the water inlet connector 22 .

[0057] In one embodiment, the hydrogen mixing device further comprises:

[0058] The ejector 5 has a water inlet connected to the water outlet of the purification device, an air inlet connected to the hydrogen outlet of the hydrogen production device 10, and a water outlet connected to the water inlet of the hydrogen mixing pump 1. The ejector 5 is used to inhale the purified water output by the purification device and the hydrogen output by the hydrogen production device 10 and mix the hydrogen and the purified water, that is, the purified water and hydrogen are mixed for the first time, so that the purified water and hydrogen can be mixed more evenly, so that the hydrogen concentration in the obtained hydrogen-rich water is higher.

[0062] The water production equipment of the present invention, due to the adoption of the above-mentioned hydrogen mixing device, can also make the purified water and hydrogen in the hydrogen-rich water mix more evenly and fully, so as to obtain hydrogen-rich water with a higher hydrogen concentration.
