Description

Technical Field

[0001] This utility model particularly relates to a hydrogen extraction core structure. Background Technology

[0002] A hydrogen extraction core is used to fix and store hydrogen-rich spheres, and can be placed in heating products such as kettles to combine with water to produce hydrogen-rich water. Existing hydrogen extraction cores consist of an upper shell and a lower shell. A threaded hole is opened in the middle of the lower shell, and a screw passes through the upper shell and is threadedly connected to the lower shell for fixation. The space enclosed by the upper and lower shells is used to hold the hydrogen-rich spheres. However, this installation method has the following two problems:

[0003] 1. The threaded connection between the upper and lower housings makes it easy for the screws to come loose during transportation, resulting in the spillage of hydrogen-rich balls.

[0004] 2. Because the hydrogen-rich spheres are small spherical structures, a large number of hydrogen-rich spheres can be placed between the upper and lower shells. The gaps between the hydrogen-rich spheres are very small. For example, when the hydrogen extraction core is placed at the bottom of the kettle and heated with water, it is difficult for the water to pass through the hydrogen extraction core near the temperature sensor of the kettle (the temperature sensor is usually located at the top of the kettle) after boiling. As a result, the temperature sensor cannot measure the temperature change after the water boils, meaning that the kettle cannot automatically shut off after the water boils. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a hydrogen extraction core structure.

[0006] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0007] A hydrogen extraction core structure includes an upper shell and a lower shell that snaps into the upper shell. The upper shell and the lower shell together form a cavity for placing a hydrogen-rich component. The bottom of both the upper shell and the lower shell has a through hole communicating with the cavity.

[0008] Preferably, the lower housing has a protrusion inside, and the upper housing has a positioning edge on its outer periphery, with the protrusion pressing the positioning edge against the lower housing.

[0009] Preferably, the hydrogen-rich component has a ring structure.

[0010] Preferably, the lower housing is recessed towards the cavity and has a first flow channel in the shape of a trumpet, wherein the diameter of the first inlet end of the first flow channel is larger than the diameter of the first outlet end.

[0024] A hydrogen extraction core structure, referenced Figures 1-3 It includes an upper shell 1 and a lower shell 2 that is snapped into the upper shell 1. The upper shell 1 and the lower shell 2 together form a cavity for placing the hydrogen-rich component 3. The bottom of the upper shell 1 and the lower shell 2 are provided with through holes 4 that communicate with the cavity.

[0025] Furthermore, a protrusion 21 is provided inside the lower housing 2, and a positioning edge 11 is provided on the outer periphery of the upper housing 1. The protrusion 21 presses the positioning edge 11 against the lower housing 2.

[0026] Furthermore, the hydrogen-rich component 3 has a ring structure.

[0027] Furthermore, the lower housing 2 is recessed in the cavity direction and is provided with a first flow channel in the shape of a trumpet, wherein the diameter of the first inlet end 511 of the first flow channel is larger than the diameter of the first outlet end 512.

[0028] Furthermore, the upper housing 1 is recessed in the cavity direction and is provided with a second flow channel in the shape of a trumpet, wherein the diameter of the second inlet end 611 of the second flow channel is smaller than the diameter of the second outlet end 612.

[0029] Furthermore, the lower housing 2 is provided with a spacer 7 on the side away from the upper housing 1.

[0030] The working principle of this utility model is as follows:

[0031] As an example of embodiment 1, this application illustrates the design concept by placing two hydrogen-rich components 3 inside the cavity. The specific placement method can be as follows: Figure 3As shown, hydrogen-rich components 3 are arranged at intervals inside the lower housing 2; then the lower housing 2 is snapped onto the upper housing 1, thus completing the installation of the hydrogen extraction core structure. The application scenario for the hydrogen extraction core structure is as follows: when the hydrogen extraction core structure and water are placed simultaneously in the heating chamber of a kettle for boiling water, the hydrogen extraction core structure will remain stationary at the bottom of the heating chamber due to its own gravity when not heated. When the kettle is heated, the temperature of the hydrogen extraction core structure and the water will rise. After the water boils, the hydrogen extraction core structure will also experience slight movement. However, because the hydrogen extraction core structure is placed flat inside the heating chamber, and the gap between the outer periphery of the hydrogen extraction core structure and the side wall of the heating chamber is very small, the hydrogen extraction core structure cannot be rotated; it can only gently swing up and down. Therefore, after boiling, the water can only pass through the lower housing 2 and the upper housing 1 in sequence. This design allows the water to come into more contact with the hydrogen-rich components 3. In this application, the hydrogen-rich components 3 are set as a ring structure. Figure 3 As can be seen, after placing the two annular hydrogen-rich components 3 inside the cavity, the remaining gap in the cavity is very large. Therefore, when the water boils, it can pass directly through the gap in the cavity through the through-hole 4 of the lower shell 2, and then through the upper shell 1, reducing the resistance to the upward movement of boiling water. Thus, the temperature sensor can promptly detect changes in water temperature. When the water boils, the temperature sensor detects the temperature feedback electrical signal and sends it to the control device, which then controls the electric kettle to cut off the power. The technical principle of the electric kettle's automatic power-off is a mature technology in this field, so its working principle will not be described in detail in this application.

[0032] Based on the above technical solution, this application also provides a spacer 7 on the lower shell 2. That is, when the hydrogen extraction core structure is placed at the bottom of the heating chamber, one end of the spacer 7 is located at the bottom of the heating chamber, so that there is a gap between the heating chamber and the lower shell 2 of the hydrogen extraction core structure. This allows more water to flow into the cavity of the hydrogen extraction core structure and contact the hydrogen-rich component 3.

[0033] Based on the above technical solution, this application provides a first flow channel in the shape of a trumpet on the lower shell 2. The diameter of the first inlet end 511 of the first flow channel is larger than the diameter of the first outlet end 512. With this design, the water flow will first flow into the first flow channel through the first inlet end 511, and then flow into the cavity through the first outlet end 512 of the first flow channel. With this design, more water flow can be introduced into the cavity.

[0034] Based on the above technical solution, this application provides a second flow channel in the shape of a trumpet recessed in the upper shell 1 towards the cavity direction, with the diameter of the second inlet end 611 being smaller than the diameter of the second outlet end 612. With this design, water that comes into contact with the hydrogen-rich component 3 first enters the second flow channel through the second inlet end 611, then flows through the second flow channel to the second outlet end 612, and finally flows out of the hydrogen extraction core structure through the second outlet end 612. This design allows for more uniform mixing of the hydrogen-rich water.

[0035] Based on the above technical solution, this application designs the upper housing 1 to be snap-fitted with the lower housing 2 instead of a threaded connection. The snap-fit ​​method can be achieved by providing a protrusion 21 on the lower housing 2 and a positioning edge 11 on the outer periphery of the upper housing 1 that snaps into the protrusion 21. The protrusion 21 can press against the positioning edge 11, thereby achieving a fixed connection between the upper housing 1 and the lower housing 2. Since this application is for heating drinking water, the upper housing 1 and the lower housing 2 are preferably made of food-grade stainless steel.

[0036] This application designs the upper shell 1 to snap together with the lower shell 2, effectively preventing the hydrogen-rich component 3 from spilling during transportation. In addition, this application designs the hydrogen-rich component 3 as a ring structure. The ring structure design allows more water to flow through the cavity, enabling the temperature sensor to detect temperature changes. Therefore, the automatic power-off performance of the electric kettle will not be affected after the water boils.

[0037] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
