[0029] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0030] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0031] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] The existing hydrogen water preparation machine is provided with an electrolytic hydrogen injection module, which includes a cathode electrolytic sheet, an ion membrane and an anode electrolytic sheet. The cathode electrolytic sheet and the anode electrolytic sheet are provided with holes that allow water to pass through. The holes on the electrolytic sheet are generally formed by punching. In order to avoid the sharp edges or burrs of the holes on the electrolytic sheet from cutting or puncturing the ion membrane, a water-permeable plate such as titanium felt is required between the electrolytic sheet and the ion membrane for isolation. Therefore, the existing electrolytic hydrogen injection module includes at least a five-layer structure including a cathode electrolytic sheet, a water-permeable partition, an ion membrane, a water-permeable partition and an anode electrolytic sheet. Therefore, the existing hydrogen-rich water machine has the disadvantages of complex structure and high production cost.

[0033] In order to overcome the above technical problems, Figure 1-4 As shown, this embodiment provides a hydrogen water preparation device, comprising:

[0034] A housing 1 having a water treatment chamber therein;

[0035] The water treatment module 2 is arranged in the water treatment chamber, and includes a water-permeable cathode plate 21, a membrane electrode 22 and a water-permeable anode plate 23 arranged in sequence;

[0036] A cathode terminal post 31 and an anode terminal post 32, the outer shell 1 is provided with a cathode through hole 116 and an anode through hole, one end of the cathode terminal post 31 contacts the water-permeable cathode plate 21, and the other end extends to the outside of the outer shell 1 through the cathode through hole 116; one end of the anode terminal post 32 contacts the water-permeable anode plate 23, and the other end extends to the outside of the outer shell 1 through the anode through hole.

[0037] Specifically, the membrane electrode 22 is preferably a proton exchange membrane, and the permeable cathode plate 21 and the permeable anode plate 23 are the same as the existing conductive permeable partition, which is conductive and can electrolyze water by electricity. Dense pores are arranged on it, which can effectively protect the membrane electrode 22 while achieving water permeability, and avoid the problem of the membrane electrode 22 being punctured by sharp objects; at the same time, the permeable cathode plate 21 and the permeable anode plate 23 on both sides can also provide support for both sides of the membrane electrode 22 respectively, avoiding the problem of the membrane electrode 22 being pierced by pressure. When setting, structures that can support the permeable cathode plate 21 and the permeable anode plate 23 are respectively arranged in the water treatment chamber, so that the permeable cathode plate 21, the membrane electrode 22 and the permeable anode plate 23 can be kept close in turn to maintain the stability of the water treatment module 2; the support structure can be an integrated structure on the outer shell 1, or it can be a support frame independent of the outer shell 1.

[0038] In conventional hydrogen water preparation machines, electrode leads are generally connected to electrodes by welding to facilitate power supply during installation. The permeable cathode plate 21 and the permeable anode plate 23 used in this embodiment are provided with dense pores, which are not suitable for wiring in the conventional welding form, and are prone to problems such as loose welding and damage to the permeable plate. This is also the reason why conventional solutions require the provision of a metal plate with high strength and good stability as an electrode plate on the outside of the titanium felt to avoid direct welding on the titanium felt to damage the titanium felt.

[0039] This embodiment directly uses permeable metal plates as the permeable cathode plate 21 and the permeable anode plate 23. To avoid welding damage, a cathode terminal post 31 and an anode terminal post 32 are respectively provided to pass through the cathode through hole 116 and the anode through hole provided on the housing 1. The power supply is connected in the form of contact, and there is no need to weld the permeable cathode plate 21 and the permeable anode plate 23, thereby avoiding the problem of welding damage to the permeable cathode plate 21 and the permeable anode plate 23. Among them, in order to ensure reliable contact, the cathode terminal post 31 and the anode terminal post 32 need to be fixedly installed, and after installation, they can respectively keep pressing the permeable cathode plate 21 and the permeable anode plate 23.

[0040] In summary, based on the hydrogen water preparation device of the present embodiment, the water treatment module 2 is provided with a three-layer structure consisting of a permeable anode plate 23, a membrane electrode 22 and a permeable cathode plate 21. Compared with the traditional electrolysis structure with five layers or even more than five layers, the structure of the water treatment module 2 of the present scheme is simpler and the cost is lower; in addition, the present scheme uses the cathode terminal post 31 and the anode terminal post 32 to contact the permeable cathode plate 21 and the permeable anode plate 23 respectively, and there is no need to weld on the permeable anode plate 23 and the permeable cathode plate 21, which can avoid problems such as unreliable welding and welding damage to the permeable anode plate 23 and the permeable cathode plate 21, thereby ensuring the durability and reliability of the device.

[0042] The cathode terminal post 31 and the anode terminal post 32 both adopt a structure composed of a column and an end cap similar to a bolt, so that the column can pass through a preset through hole and the end cap can be reliably restricted to the inner side of the housing 1, so that the cathode terminal post 31 and the anode terminal post 32 can be reliably fixed on the housing 1 to maintain contact with the permeable cathode plate 21 and the permeable anode plate 23, ensuring reliable power supply.

[0046] After installation, the cathode end cap 312 and the anode end cap 322 are aligned with each other, and the cathode end cap 312 and the anode end cap 322 can form a tight structure, so that the cathode end cap 312 and the anode end cap 322 can respectively keep pressing the permeable cathode plate 21 and the permeable anode plate 23 to ensure contact reliability.

[0047] In one embodiment, the housing 1 includes an anode shell plate 12 and a cathode shell plate 11 , the cathode shell plate 11 is provided with a first groove 113 , the anode shell plate 12 is provided with a second groove, and the first groove 113 and the second groove constitute the water treatment chamber.

[0048] The housing 1 is formed by putting together a cathode shell plate 11 and an anode shell plate 12. When installing, first install the cathode terminal 31 and the anode terminal 32 on the cathode shell plate 11 and the anode shell plate 12, respectively, and then install the water treatment module 2 on the first groove 113 or the second groove, and finally cover the other shell plate and fix it. This structure has the advantage of easy installation.

[0049] Preferably, a first hole is provided on the cathode shell plate 11 around the first groove 113, and a second hole is correspondingly provided on the anode shell plate 12. A fastening bolt is passed through the first hole and the second hole and then connected with a nut to fix the anode shell plate 12 and the cathode shell plate 11.

[0050] Preferably, a fool-proof protrusion is provided on one side of the first groove 113 on the cathode shell plate 11, and a fool-proof groove is correspondingly provided on one side of the second groove on the anode shell plate 12.

[0051] In one embodiment, the housing 1 further includes a waterproof ring 13 disposed around the inner circumference of the water treatment chamber, and the waterproof ring 13 is pressed tightly between the anode shell plate 12 and the cathode shell plate 11 .

[0052] A waterproof ring 13 is arranged around the water treatment chamber to seal the gap between the anode shell plate 12 and the cathode shell plate 11 to prevent water leakage.

[0053] Preferably, two waterproof rings 13 are provided, one on the anode shell plate 12 and one on the cathode shell plate 11 respectively. After installation, the two waterproof rings 13 are completely aligned and crimped.

[0055] Reference Figure 5 A tortuous first flow channel 114 is provided on the cathode shell plate 11, water flows in from the cathode water inlet joint 111, and is fully contacted with the permeable cathode plate 21 for electrolysis during the process of passing through the first flow channel 114, and the hydrogen formed by electrolysis is dissolved in the remaining water to form hydrogen-rich water, and then discharged from the cathode water outlet joint 112; the second flow channel on the anode shell plate 12 is completely corresponding to the first flow channel 114 on the cathode shell plate 11, water flows in from the anode water inlet joint 121, and is fully contacted with the permeable anode plate 23 for electrolysis during the process of passing through the second flow channel, and the oxygen formed by electrolysis is dissolved in the remaining water to form waste water, and then discharged from the anode water outlet joint 122.

[0056] In this solution, the first flow channel 114 and the second flow channel are provided for conveying water, so that the water can be fully treated after being fully contacted with the water treatment module 2, thereby increasing the hydrogen content of the treated hydrogen-rich water.

[0057] The cathode water inlet connector 111 and the cathode water outlet connector 112 are connected to the first flow channel 114 through the cathode water inlet hole and the cathode water outlet hole respectively. Preferably, the aperture of the cathode water inlet hole is larger than the aperture of the cathode water outlet hole, so as to increase the pressure in the water treatment chamber and promote the dissolution of gas in water; similarly, the anode water inlet connector 121 and the anode water outlet connector 122 are connected to the second flow channel through the anode water inlet hole and the anode water outlet hole respectively. Preferably, the aperture of the anode water inlet hole is larger than the aperture of the anode water outlet hole.

[0064] The connector 4 of this embodiment can be used to facilitate the connection of water pipes.

[0065] Specifically, refer to Figure 6 The cathode water inlet joint 111, the cathode water outlet joint 112, the anode water inlet joint 121 and the anode water outlet joint 122 are respectively provided with stepped mounting holes; the fixing ring 42 is fixedly installed on the outermost layer of the stepped mounting hole, which is preferably a metal ring, and is fixedly installed in the form of interference fit, and a shrinkage cone is provided on the inner side of the fixing ring 42; the jacket 43 includes an annular seat and a plurality of claws connected to one side of the annular seat, and the claws extend into the fixing ring 42; the sealing ring 41 is installed in the stepped mounting hole When in use, the external water pipe passes through the jacket 43 and extends inwardly to abut the sealing ring 41. When the water pipe is directly pulled outward, the jacket 43 will be driven to move outward relative to the fixing ring 42. The contraction cone 421 of the fixing ring 42 will squeeze the claws on the jacket 43 together and contract to hold the water pipe tightly to prevent the water pipe from continuing to move outward, thereby achieving the fixation of the water pipe after installation. When the water pipe needs to be removed, it is only necessary to press the jacket 43 inward to keep the jacket 43 in a relaxed state, and then the water pipe can be pulled out.
