Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more specifically, to a flow-through type water electrolysis device. Background Technology

[0002] An electrolysis water device is a device that uses electrical energy to decompose water into hydrogen and oxygen. It is widely used in laboratories, industrial production, and household purification.

[0003] Chinese utility model patent CN204162801U discloses a water electrolysis device, comprising multiple electrolysis zones and a water transport zone. Each electrolysis zone contains an electrolysis chamber with a negative electrode and a positive electrode on each side, and one or more internal electrode plates. The electrolysis zone also has an electrolyte inlet for electrolyte to flow into the electrolysis chamber. The water transport zone contains a water transport chamber connected to the electrolysis chamber by a one-way valve. The water transport chamber has a water inlet for introducing tap water, and the one-way valve allows gas generated in the electrolysis zone to enter the water transport chamber, mix with water, and flow out through a water outlet. These electrolysis zones are connected to the water transport zone in series or parallel to produce different concentrations or volumes of electrolyzed water to meet various needs. However, the electrolysis water device in the above technical solution installs the electrolysis zone and the water transport zone on the cabinet, which occupies a large space and easily restricts the usable space of the electrolysis water device. In addition, the setting of the electrolysis zone and the water transport zone requires the installation of many small structures in a limited space, such as sensors, multiple internal electrode plates, positive electrode plates, vortex mixers, etc., which are difficult to manufacture and produce, have high manufacturing and maintenance costs, and poor practicality.

[0035] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] Please see Figure 1-6 As shown, this utility model embodiment provides a flow-through electrolysis water device, including a shell structure, an electrolysis structure, and potting compound 5.

[0038] The outer shell structure includes a shell 1 and a top cover 4. The top cover 4 is installed on the open side of the shell 1. The shell 1 is provided with an inlet 11 and an outlet 12 on the side away from the top cover 4. The position of the inlet 11 is lower than that of the outlet 12. When liquid is injected, the liquid enters the inner side of the shell 1 from the inlet 11, and the liquid level rises as the liquid is continuously injected. When the liquid level reaches the position of the outlet 12, the liquid will flow out from the outlet 12. At this time, it means that the liquid in the shell 1 has submerged the electrolytic structure located in the shell 1.

[0039] The electrolysis structure includes a cathode plate 2, an anode plate 3, and an electron wire 6. The cathode plate 2 and the anode plate 3 are inserted on the side of the upper cover 4 away from its opening, and the electron wire 6 is located on the opening side of the upper cover 4 and connected to the cathode plate 2 and the anode plate 3. The cathode plate 2 and the anode plate 3 are located inside the shell 1. The overall structure of the electrolysis structure is simple and compact, which can not only maintain a good electrolysis effect but also effectively reduce the manufacturing difficulty and production cost.

[0040] Encapsulating compound 5 is disposed on the inner side of the upper cover 4 to fix the electrolytic structure to the upper cover 4. Encapsulating compound 5 facilitates sealing of the upper cover 4, thereby protecting the inner structure of the upper cover 4 from environmental influences while maintaining the connection and installation stability of the inner structure of the upper cover 4, and effectively improving the mechanical strength and electrical insulation of the upper cover 4.

[0041] As a further description of the above solution, the simple composition of the electrolysis structure helps to reduce the manufacturing difficulty while reducing the size of the device. This not only effectively reduces production costs but also helps to reduce the limitations of the available space on the use of the water electrolysis device, greatly improving the practicality and adaptability of the water electrolysis device.

[0042] Please see Figure 1-5 As shown, the upper cover 4 includes an outer shell 41 located on the opening side of the housing 1, and an inner insert block 42 and a positioning protrusion ring 43 installed on the side of the outer shell 41 near the housing 1. The outer wall size of the inner insert block 42 is adapted to the inner wall size of the housing 1. This facilitates the insertion of the housing 1 and the upper cover 4 by inserting the inner insert block 42 in the upper cover 4 into the housing 1, thereby placing the electrolytic structure installed on the upper cover 4 inside the housing 1.

[0043] Please see Figure 3 and Figure 5 As shown, the inner wall size of the positioning protrusion 43 is larger than the outer wall size of the inner insert block 42, and the outer wall size of the positioning protrusion 43 is smaller than the outer wall size of the outer shell 41. The shell 1 has an annular groove 15 that matches the size of the positioning protrusion 43 on the side near the upper cover 4. This facilitates the use of the insertion action of the positioning protrusion 43 and the annular groove 15 to improve the docking accuracy of the upper cover 4 and the shell 1 and enhance their connection tightness.

[0044] Please refer to the figure. Figure 3 , Figure 5 Figure 6 As shown, the bottom of the inner insert 42 is provided with a tenon 422, and the inner wall of the housing 1 is provided with a tenon groove 16 that matches the size of the tenon 422. When the upper cover 4 is connected to the housing 1, the tenon 422 in the upper cover 4 is tenoned with the housing 1 using the tenon groove 16, thereby facilitating the further improvement of the docking accuracy and connection firmness of the upper cover 4 and the housing 1 through the cooperation of the tenon 422 and the tenon groove 16.

[0045] Please see Figure 2-4As shown, the cathode plate 2 includes a first plate and a first connecting block installed on one side of the first plate along its length. The anode plate 3 includes a second plate and a second connecting block installed on one side of the second plate along its length. The first plate is located directly above the second plate, and the first connecting block and the second connecting block are arranged in parallel and staggered.

[0046] Please see Figure 2-5 As shown, the first plate and the second plate are provided with a number of evenly distributed water-permeable holes. The inner insert 42 is provided with a first insertion hole and a second insertion hole on the side near the shell 1, which correspond to the positions of the first connecting insert and the second connecting insert. This allows the first connecting insert and the second connecting insert to extend to the inside of the upper cover 4 through the provided first insertion hole and the second insertion hole to connect with the electronic wire 6. The water-permeable holes allow the liquid to move upward through the water-permeable holes during liquid injection, thereby ensuring the contact effect between the liquid and the cathode plate 2 and the anode plate 3.

[0047] Please see Figure 3-5 As shown, a number of retaining strips 421 are installed on the side of the inner insert block 42 away from the outer shell 41, and the positions of the retaining strips 421 are staggered from the installation positions of the first connecting insert block and the second connecting insert block. The first plate and the second plate are respectively provided with a first slot 21 and a second slot 31 that are adapted to the shape and size of the retaining strips 421 on the side near the inner insert block 42. This facilitates the use of the interlocking action of the retaining strips 421 with the first slot 21 and the second slot 31 to restrict the lateral movement of the cathode plate 2 and the anode plate 3, thereby improving the installation stability of the cathode plate 2 and the anode plate 3.

[0048] Please see Figure 6 As shown, limit slides 13 are installed on both sides of the inner wall of the housing 1 in the width direction. Two parallel sliding grooves are horizontally arranged on the limit slides 13. The distance between the two sliding grooves is adapted to the distance between the first plate and the second plate. The size of the two sliding grooves is adapted to the thickness of the first plate and the second plate. It is convenient to use the sliding grooves to extend the edges of the first plate and the second plate into the limit slides 13, thereby using the limit slides 13 to support the edges of the first plate and the second plate, and further improving the stability of the cathode plate 2 and the anode plate 3.

[0049] Please see Figure 6 As shown, a positioning seat 14 is installed on the inner wall of the housing 1 away from the upper cover 4, and a notch is provided on the side of the positioning seat 14 close to the upper cover 4. The vertical dimension of the notch is adapted to the distance from the upper surface of the first plate to the lower surface of the second plate. This allows the cathode plate 2 and the anode plate 3 to extend into the positioning seat 14 through the notch, thereby restricting the vertical movement of the center of symmetry in the width direction of the first plate and the second plate by the positioning seat 14, further improving the stability of the cathode plate 2 and the anode plate 3.

[0050] Please see Figure 1-2 As shown, the electronic wire 6 includes a plug 62 and two wires 61 mounted on the plug 62 and fixedly connected to the first connecting plug and the second connecting plug, respectively; the plug 62 and the wires 61 facilitate the connection of the cathode plate 2 and the anode plate 3 to an external power supply device, thereby providing power for water electrolysis.

[0051] The working process of the above-mentioned flow-through water electrolysis device is as follows:

[0052] When assembling this flow-through water electrolysis device, the first connecting blocks and the second connecting blocks of the cathode plate 2 and the anode plate 3 need to be inserted into the inner blocks 42 of the upper cover 4 respectively. Then, the two wires 61 of the electron wire 6 are connected and fixed to the first connecting blocks and the second connecting blocks on the cathode plate 2 and the anode plate 3 on the inside of the upper cover 4. After that, only potting glue 5 needs to be applied to the inside of the upper cover 4 to fix the cathode plate 2, the anode plate 3 and the electron wire 6 into the upper cover 4. Finally, the assembly operation is completed by assembling the upper cover 4 with the shell 1 so that the cathode plate 2 and the anode plate 3 are in the shell 1.

[0053] In use, liquid needs to be injected into the shell 1 through the inlet 11. The liquid enters the inside of the shell 1 through the inlet 11 and the liquid level rises as the liquid is continuously injected. When the liquid level reaches the outlet 12, the liquid will flow out from the outlet 12. At this time, it means that the liquid in the shell 1 has submerged the electrolysis structure located in the shell 1. After that, it is only necessary to connect the external power supply equipment through the plug 62 in the electronic wire 6 to form a flow-through electrolysis structure. The effect of electrolyzing water can be controlled by controlling the output of the external power supply equipment.

[0054] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
