[0041] Embodiment 1

[0042] The present invention provides a puncturing structure for a household appliance sterilization box, as Figure 1 , Figure 3 shown, which includes a puncturing structure body 150 installed in the household appliance sterilization box 100, and the puncturing structure body 150 is arranged at one end of the sterilization box 100; the puncturing structure body 150 includes a puncturing end for puncturing the partition layer 130 used to separate the chambers in the sterilization box 100; wherein, an outer surface of the puncturing structure body 150 facing the household appliance inner tank 2 is provided with a connecting structure for rotatably fastening to the inner wall of the inner tank 2.

[0043] When installing the sterilization box 100, rotate the puncturing structure body 150 to drive the connecting structure to rotate and fasten to the inner wall of the inner tank 2, thereby completing the installation of the sterilization box 100.

[0044] When activating the sterilization box 100, an external force drives the puncturing structure body 150 to approach the partition layer 130, so that the puncturing end punctures the partition layer 130.

[0045] In one embodiment, the puncturing structure body 150 is arranged in the first chamber 110 of the sterilization box 100; an external force drives the puncturing structure body 150 to approach the partition layer 130 provided in the sterilization box 100 for separating the first chamber 110 and the second chamber 120, so as to puncture the partition layer 130, enabling the first reactant in the first chamber 110 to be mixed with the second reactant in the second chamber 120 of the sterilization box 100 and react to generate a volatile fungicide. The volatile fungicide overflows from the air vent (not shown in the figure) of the sterilization box to the household appliance box body to sterilize the household appliance box body. Further, a sealing ring 180 is provided between the puncturing structure body 150 and the inner wall of the first chamber 110 of the sterilization box 100 to prevent the reactant in the first chamber 110 from leaking between the puncturing structure body 150 and the inner wall of the first chamber 110 of the sterilization box 100. The puncturing structure body 150 can be driven to approach the partition layer 130 of the sterilization box 100 by manual or mechanical force.

[0046] In one embodiment, the outer circumferential outer wall of the puncturing structure body 150 is provided with an external thread for threadedly connecting with the inner wall of the first chamber 110 of the sterilization box 100 provided with an internal thread, that is, the puncturing structure body 150 can be screwed in and out in the first chamber 110.

[0047] For the first chamber 110 of the rotary sterilization cartridge 100, the piercing structure body 150 rotates therewith, so that the connecting structure provided on the piercing structure body 150 is buckled on the inner wall of the inner container 2 as it rotates, completing the installation of the sterilization cartridge 100; in an embodiment, when the rotary sterilization cartridge 100 rotates, the first chamber 110 rotates therewith; wherein,

[0048] After the piercing structure body 150 is rotationally buckled on the inner wall of the inner container 2 by rotating the first chamber 110, continue to rotate the first chamber 110 in the same direction so that the piercing structure body 150 is screwed into the first chamber 110 to approach the partition layer 130 provided in the sterilization cartridge 100 for separating the first chamber 110 and the second chamber 120, so as to pierce the partition layer 130, enabling the first reactant in the first chamber 110 to be mixed with the second reactant in the second chamber 120 and react to generate a volatile bactericide. The volatile bactericide overflows from the air vent (not shown in the figure) of the sterilization cartridge to the household appliance cabinet body to sterilize the household appliance cabinet body; the rotation direction of the first chamber 110 when the piercing structure body 150 is rotationally buckled on the inner wall of the inner container 2 is the same as the rotation direction of the first chamber 110 when the piercing structure body 150 is screwed into the first chamber 110, so as to prevent the rotation direction of the first chamber 110 when the piercing structure body 150 is screwed into the first chamber 110 from being opposite to the rotation direction of the first chamber 110 when the piercing structure body 150 is rotationally buckled on the inner wall of the inner container 2, which may cause the piercing structure body 150 to rotate when starting to pierce, resulting in the piercing structure body 150 being disengaged from the buckling on the inner wall of the inner container 2 and causing the sterilization cartridge 100 to drop. When designing the piercing structure body 150, the rotation angle of the piercing structure body 150 (i.e., the first chamber 110) when the piercing structure body 150 is rotationally buckled on the inner wall of the inner container 2 and the rotation angle of the first chamber 110 when piercing the partition layer 130 can be specifically defined, so as to facilitate installation and opening of the piercing. For example, the piercing structure body 150 rotates 15° to buckle the piercing structure body 150 on the inner wall of the inner container 2 to complete the installation of the sterilization cartridge 100, and then continue to rotate the first chamber 110 in the same direction to 180° so that the piercing structure body 150 pierces the partition layer 130. Since the piercing structure body 150 is fixed on the inner wall of the inner container 2 and the continued rotation direction of the first chamber 110 is the same as the rotation direction when the piercing structure body 150 is buckled on the inner wall of the inner container 2, when continuing to rotate the first chamber 110 in the same direction, the piercing structure body 150 is tightly buckled on the inner wall of the inner container 2, that is, the piercing structure body 150 does not move relative to the inner wall of the inner container 2 but performs a screwing-in movement relative to the first chamber 110, and finally pierces the partition layer 130.

[0049] The piercing structure body 150 is cylindrical, and the outer contour of the piercing structure body 150 is close to the inner contour of the first chamber 110 to prevent the reactants stored in the sterilization cartridge 100 from leaking from the connection between the piercing structure body 150 and the first chamber 110.

[0050] In one embodiment, the puncturing end includes a plurality of first sharp corners 151 provided on the end surface of the puncturing structure body 150 facing the separation layer 130, so that the puncturing end can puncture the separation layer 130. Further, the plurality of first sharp corners 151 are arranged in an annular array. As the puncturing structure body 150 rotates, the plurality of first sharp corners 151 apply a puncturing force on the separation layer 130 along the trajectory of the circumference where the first sharp corners 151 are located, so as to expand the torn opening of the separation layer 130, and improve the mixing speed of the first reactant in the first chamber 110 and the second reactant in the second chamber 120.

[0051] In one embodiment, the first sharp corner 151 faces the connection between the separation layer 130 and the inner contour of the first chamber 110, so as to puncture the separation layer 130 and make the separation layer 130 separate from the connection with the inner contour of the first chamber 110, that is, to completely expose the opening of the first chamber 110 facing the second chamber 120, so as to improve the mixing speed of the first reactant in the first chamber 110 and the second reactant in the second chamber 120, and at the same time make the first reactant and the second reactant fully mixed, and improve the utilization rate of the reaction raw materials.

[0052] In one embodiment, the puncturing structure body 150 has a hollow structure; the puncturing end includes a second sharp corner 152 axially provided in the hollow area of the puncturing structure body 150. Further, the second sharp corner 152 points to the central position of the separation layer 130 to act simultaneously with the first sharp corner 151 to accelerate the puncturing of the separation layer 130.

[0053] In one embodiment, a clamping groove 153 for clamping the sealing ring 180 is provided on the circumferential side of the end of the puncturing structure body 150 close to the separation layer 130. After the sealing ring 180 is clamped in the clamping groove 153, the sealing performance between the puncturing structure body 150 and the inner wall of the first chamber 110 is improved, and the first reactant and / or the second reactant in the sterilization box 100 are prevented from overflowing from the connection between the puncturing structure body 150 and the inner wall of the first chamber 110 to the outside of the sterilization box 100, resulting in waste of raw materials and reduced use safety.

[0054] In one embodiment, as Figure 2 、 Figure 3 、 Figure 4 shown, the puncturing structure body 150 is provided with a second mounting portion 520 to rotatably engage with a first mounting portion 510 provided on the mounting seat 200 mounted on the inner container 2. When the sterilization box 100 needs to be removed from the mounting structure body 500, it can be reversely rotated to make the puncturing structure body 150 disengage from the inner wall of the inner container 2. Further, the first mounting portion 510 and the second mounting portion 520 are rotatably engaged through the buckle structure after the convex rib is inserted into the groove.

[0055] Further, in one embodiment, the convex rib of the first mounting portion 510 is separately provided from the corresponding first inverted structure, and the groove of the second mounting portion 520 is separately provided from the corresponding second inverted structure. After the convex rib of the first mounting portion 510 extends into the groove of the second mounting portion 520, the convex rib can rotate or rotate a certain distance in the groove until the first inverted structure and the second inverted structure are engaged. Among them, the convex rib and the groove play an auxiliary positioning role to increase the installation speed. Further, the first inverted structure and the second inverted structure are engaged, and the groove of the second mounting portion 520 plays a limiting role on the convex rib of the first mounting portion 510 to prevent continued rotation in the same direction from causing the first inverted structure and the second inverted structure to disengage.

[0056] In another embodiment, the second mounting portion 520 includes two arc-shaped grooves respectively provided with the second inverted structure; the two arc-shaped convex ribs respectively provided with the first inverted structure of the first mounting portion 510 extend into the two grooves of the second mounting portion 520, and rotate to make the matching first inverted structure and the second inverted structure engage with each other. In one embodiment, the arc lengths of the two grooves of the second mounting portion 520 are different, and the two grooves are located on the same circumference. The large and small structures of the two grooves can play a fool-proof role. For example, the puncture structure body 150 rotates from the large groove to the small groove, which is the direction of installing the sterilization box 100, and the reverse direction is the rotation direction of disassembling the sterilization box 100. In another embodiment, the two grooves are rotationally symmetrical, and the arc lengths of the two grooves are the same. The two rotationally symmetrical grooves are easy to process. It should be understood that the arc length of the groove provided in the second mounting portion 520 is slightly longer than the arc length of the convex rib provided in the first mounting portion 510, that is, the convex rib provided with the first inverted structure can be smoothly inserted into the matching groove. When the first inverted structure is rotated to engage with the second inverted structure, a gap is left between a side wall of the groove away from the inverted buckle connection and an end of the corresponding convex rib away from the inverted buckle connection, and the gap is not large enough to make the first mounting portion 510 and the second mounting portion 520 easily detached. When the second inverted structure of the second mounting portion 520 is engaged with the first inverted structure provided in the first mounting portion 510, the gap between a side wall of the groove away from the inverted buckle connection and an end of the corresponding convex rib away from the inverted buckle connection increases, so that the puncture structure body 150 can be smoothly removed from the first mounting portion 510 when the structure body 150 is rotated in the reverse direction. Among them, the increased arc distance is the arc length of the first inverted structure and / or the second inverted structure. Further, the arc length of the first inverted structure is the same as that of the second inverted structure.

[0057] Further, the second reverse buckling structure of the second installation part 520 of the puncturing structure body 150 is arranged at one end of the groove, and the positions of the second reverse buckling structures of the two grooves are opposite. The second reverse buckling structure is arranged at one end of the groove facing the rotation direction during buckling. When the second reverse buckling structure is buckled with the first reverse buckling structure on the inner wall of the inner container 2, the sterilization box 100 is hung on the inner wall of the inner container 2, and when there is no external force for reverse rotation, the second reverse buckling structure and the first reverse buckling structure cannot be separated from the buckled state. It should be understood that when the sterilization box 100 is installed, the positions of the two grooves are such that after the first reverse buckling structure and the second reverse buckling structure are buckled, they will not be separated from the buckled state due to the self-gravity of the sterilization box 100. Preferably, the sterilization box 100 is installed at the top of the inner container, and the gravity direction of the sterilization box 100 is perpendicular to the rotation buckling direction of the first reverse buckling structure and the second reverse buckling structure. The gravity of the sterilization box 100 cannot cause the sterilization box 100 to be separated from the mounting seat 200, so there is no need to pay attention to the relative position relationship between the two grooves and the inner container, reducing the requirement for assembly accuracy.

[0058] Further, as Figure 2 , Figure 3 shown, a second reverse buckling structure is formed by the inner concave of one end of the groove, that is, the second reverse buckling structure is hidden on one side of the groove.

[0059] Specifically, as Figure 2 , Figure 3 , Figure 4As shown in the figure, the first installation part 510 includes a first rib 511 with a first reverse buckle 513 at one end and a second rib 512 with a second reverse buckle 514 at one end. The first rib 511 and the second rib 512 are rotationally symmetric, and the first reverse buckle 513 and the second reverse buckle 514 are respectively located at opposite ends of the first rib 511 and the second rib 512. The second installation part 520 includes a first groove 521 with a third reverse buckle 523 recessed at one end and a second groove 522 with a fourth reverse buckle 524 recessed at one end. When installing the sterilization box 100, align the side of the sterilization box 100 with the first groove 521 and the second groove 522 with the side of the mounting base 200 with the first rib 511 and the second rib 512 until the first rib 511 and the second rib 512 of the mounting base 200 respectively extend into the corresponding first groove 521 and second groove 522 of the sterilization box 100, and rotate in the direction of the third reverse buckle 523 and / or the fourth reverse buckle 524 until the first reverse buckle 513 and the second reverse buckle 514 are respectively snapped into the third reverse buckle 523 and the fourth reverse buckle 524, so that the first reverse buckle 513 and the second reverse buckle 514 are respectively buckled with the third reverse buckle 523 and the fourth reverse buckle 524 to complete the installation of the sterilization box 100. Further, the inner contour of the third reverse buckle 523 in the shape of a card slot wraps the outer contour of the first reverse buckle 513, and the inner contour of the fourth reverse buckle 524 in the shape of a card slot wraps the outer contour of the second reverse buckle 514, so that when there is no external force to rotate the sterilization box 100, the sterilization box 100 cannot be detached from the mounting base 200, ensuring the stable installation of the sterilization box 100 and not easily falling off during use.

[0060] Embodiment 2

[0061] The present invention provides a sterilization module, as Figure 4 、 Figure 5 、 Figure 6 shown, including a sterilization box 100, the sterilization box 100 includes a first chamber 110, a second chamber 120, and a partition layer 130 for separating the first chamber 110 and the second chamber 120; the first chamber 110, the partition layer 130, and the second chamber 120 are arranged in sequence along the direction away from the inner wall of the inner container 2 for installing the sterilization box 100; it further includes a puncturing structure body 150 of a puncturing structure for a household appliance sterilization box as described above; the puncturing structure body 150 is arranged at one end of the bacteria box 100; wherein,

[0062] Rotate the puncturing structure body 150 so that one side of the puncturing structure body 150 is rotationally buckled on the inner wall of the inner container 2 of the household appliance to install the sterilization box 100 on the inner container 2.

[0063] In one embodiment, the outer peripheral side of the puncturing structure body 150 is threadedly connected to the inner wall of the first chamber 110. Rotate the sterilization cartridge 100 so that one side of the puncturing structure body 150 is rotationally snapped onto the inner wall of the inner container 2 of the household appliance, and continue to rotate in the same direction so that the puncturing structure body 150 is screwed into the first chamber 110 to puncture the separation layer 130, so that the first reactant in the first chamber 110 is mixed with the second reactant in the second chamber 120 and reacts to generate a volatile bactericide.

[0064] Furthermore, the volatile bactericide is chlorine dioxide gas. The two reactants used to react to generate chlorine dioxide gas are a solid-phase reactant and a liquid-phase reactant. In one embodiment, the sterilization cartridge 100 is installed at the top of the inner wall of the household appliance box body. The first reactant stored in the first chamber 110 is solid-phase, and the second reactant stored in the second chamber 120 is liquid-phase. After the puncturing structure body 150 punctures the separation layer 130, the first reactant drops from the first chamber 110 into the second chamber 120, mixes with the second reactant in the second chamber 120 and reacts to generate chlorine dioxide gas. The generated chlorine dioxide gas overflows from the air vent provided on the sterilization cartridge 100 into the household appliance box body for sterilization. Further, a breathable membrane (not shown in the figure) is provided on the side of the air vent facing the household appliance box body. The breathable membrane is breathable and isolates liquids and solids to prevent the liquid in the sterilization cartridge 100 from leaking from the air vent.

[0065] Embodiment 3

[0066] As Figure 6 shown, the present invention also provides a refrigerator, including a refrigerator box body, and the inner wall of the inner container 2 of the refrigerator box body is provided with a sterilization module as described above; the sterilization cartridge 100 of the sterilization module is rotationally snapped onto the inner wall of the inner container 2 through the puncturing structure body 150. First, fix the mounting seat 200 on the refrigerator inner container 2, and then rotationally snap the sterilization cartridge 100 onto the mounting seat 200 through the connection structure provided on the puncturing structure body 150. Continue to rotate the puncturing structure body 150 in the same direction to trigger the reaction to generate a volatile bactericide. When the volatile bactericide in the sterilization cartridge 100 is consumed, remove the sterilization cartridge 100 for replacement.

[0067] Compared with the prior art, the present invention provides a puncturing structure for a household appliance sterilization cartridge. Rotate the puncturing structure body, and it is rotationally snapped onto the inner wall of the inner container of the household appliance box body through the connection structure provided on the puncturing structure body, completing the installation of the sterilization cartridge. The installation is convenient and detachable, facilitating the replacement of the sterilization cartridge. Further, continue to rotate the sterilization cartridge in the same direction. Since the puncturing structure body is firmly fastened to the inner container, the rotational force causes the puncturing structure body to be screwed into the first chamber of the sterilization cartridge until the puncturing end punctures the separation layer separating the first chamber and the second chamber, triggering the generation reaction of the volatile bactericide and starting the use of the sterilization cartridge.

[0068] The above are only the preferred embodiments of the present invention and do not impose any formal restrictions on the present invention. Any ordinary technician in the industry can smoothly implement the present invention according to the illustrations in the specification and the above content. However, any minor changes, modifications, and equivalent variations made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the substantial technology of the present invention still fall within the protection scope of the technical solution of the present invention.
