Detailed Description

In order that the utility model described herein may be more fully understood, the following examples are set forth. It should be understood that these examples are for illustrative purposes only and are not to be construed as limiting the invention in any way.

Example one

As shown in fig. 1 to 6, a push rod structure of a sterilization module for home appliances such as refrigerators and freezers for storing articles. The structure includes: the ejector rod 15 is used for breaking an isolation structure in the household appliance sterilization module 100; the ejector rod 15 has a gap with the isolation structure before the household appliance sterilization module is not activated or the ejector rod contacts the isolation structure but is not enough to break the isolation structure; when the household appliance sterilization module is activated, the ejector rod 15 moves in the accommodating part in the household appliance sterilization module to break the isolation structure in the household appliance sterilization module 100, so that at least two reactants in the isolation state in the household appliance sterilization module are mixed with each other to generate volatile matters for sterilization. Breaking the isolation structure can be understood as that when the isolation structure is made of a breathable and waterproof material, such as a breathable film (PE film, PUW film, etc.), silica gel, etc., the rod can be a rod with a piercing structure to pierce the isolation structure; in other embodiments, when the isolation structure is a housing, the top cover jacks up the housing, i.e., the ejector 15 breaks the isolation structure.

Specifically, the gas permeable membrane 13 is made of a gas permeable and water impermeable material, which may be a gas permeable membrane (such as a PE membrane, a PUW membrane, etc.), a silica gel, a non-woven fabric, etc., on one hand, which is capable of facilitating the gas of the volatile matter to pass through, and on the other hand, which is capable of blocking the liquid from overflowing the household appliance sterilization module 100, and in addition, the gas permeable membrane 13 may prevent the dust outside the sterilization module 100 from entering the household appliance sterilization module. Because different breathable films 13 have different breathable rates, the breathable films 13 can be selected according to the volume of the household appliance, so as to adjust the breathable amount of the volatile matters in the same time period.

It should be understood that the accommodating portion 102 provides a corresponding movement space for the rod 15, the accommodating portion 102 is specifically disposed inside the home appliance sterilization module 100, and one end of the accommodating portion 102 is disposed near the isolation structure, so that the rod collides against the isolation structure and breaks the isolation structure after moving inside the home appliance sterilization module 100.

The structure also comprises at least one sealing component 17 which is sleeved on the periphery of the ejector rod 15; the mandril 15 moves in the accommodating part 102 in the household electric sterilizing module; before and after the household appliance sterilization module is activated, the rod 15, the sealing member 17 and the accommodating portion 102 can form a sealed space together, so as to prevent the reactant or the product of the reactant in the household appliance sterilization module 100 from flowing out of the accommodating portion 102. Specifically, the top bar 15 is configured to jack up the first box 11, and it should be noted that, after the first box 11 is jacked up, the first box 11 may fall or the first box 11 still remains at the original position; the structure further includes at least one sealing member 17, and in order to save cost and simplify the structure, the sealing member 17 may be a sealing gasket, and the sealing gasket is sleeved on the top rod 15 and located between the top rod 15 and the accommodating portion 102. Before the household appliance sterilization module 100 is activated and after the household appliance sterilization module 100 is activated, a sealed space is always reserved among the ejector rod 15, the sealing member 17 and the accommodating part 102, so that substances in the household appliance sterilization module can not leak out.

If the structure includes a sealing member 17, and the sealing member 17 is a sealing gasket, the sealing gasket may cause insufficient sealing between the push rod 15 and the accommodating portion 102 if the sealing gasket covers only a small portion of the push rod 15 (e.g., one tenth of the length of the push rod 15); if the sealing washer covers most of the rod 15 (e.g., half of the length of the rod 15), a large friction force is often provided to the rod 15, so that the rod 15 cannot easily move in the accommodating portion 102 after receiving an external force. Therefore, when the sealing member 17 is a sealing gasket having a small thickness and covering only a small portion of the stem 15, the structure may include a plurality of sealing members 17 to enhance the sealing between the stem 15 and the accommodating portion 102. When a plurality of sealing members 17 are included, in order to reduce the influence on the free movement of the carrier rod 15, the plurality of sealing members 17 are dispersed on the periphery of the carrier rod 15, that is, a distance exists between every two sealing members 17, and the distance is between one third and one half of the carrier rod 15. When there are several sealing members 17, at least one sealing member 17 is disposed at the end of the rod 15 far from the first box 11, that is, the end of the rod 15 is sealed at the entrance of the accommodating portion 102 by the sealing member 17, so as to ensure that the reactant and/or the reactant product does not leak out of the module 100.

In some embodiments, the stem 15 includes a groove 151, and the sealing member 17 is disposed in the groove 151, such that when the stem 15 is assembled in the receiving portion 102, the sealing member 17 forms a seal between the stem 15 and the receiving portion 102 at the groove 151. At this time, since the sealing member 17 is fixedly connected to the header rod 15 by the groove, the sealing member 17 itself does not move around in the accommodating portion 102, and the sealability between the header rod 15 and the accommodating portion 102 is improved. When the at least one sealing member 17 is disposed at the end of the top bar 15 far from the first box 11, the top bar 15 is preferably a top bar 15 with a protruding portion at the head end, and when the top bar 15 is cylindrical, the protruding portion disposed at the head end of the top bar 15 is a circular boss, and the sealing member 17 is sleeved on the circular boss.

Example two

As shown in fig. 1 to 6, a sealing structure includes the top bar structure of the household appliance sterilization module in the above embodiments, and further includes a receiving portion 102 for the top bar 15 to move; the top rod 15 pushes against the isolation structure after moving in the accommodating portion 102, and the accommodating portion 102, the top rod 15 and the sealing member form a sealed space together, so as to prevent the reactant or the product of the reactant in the household appliance sterilization module from flowing out of the accommodating portion. In some embodiments, the accommodating portion 102 is disposed on the bottom cover 10, and the shape and size of the accommodating portion 102 are required to facilitate the free movement of the rod 15 in the accommodating portion 102, and at the same time, the rod 15 will not easily fall from the accommodating portion 102. In some embodiments, the receptacle 102 is a circular chamber when the ram 15 is cylindrical. The structure also comprises at least one sealing component 17, wherein the sealing component 17 is assembled between the top rod 15 and the accommodating part 102 to ensure that the top rod 15 and the accommodating part 102 form a seal; in order to save cost and simplify the structure, the sealing member 17 may be a sealing washer, which is sleeved on the top rod 15 and located between the top rod 15 and the accommodating portion 102. This isolation structure can be first box body 11, first box body 11 and bottom 10 fixed connection, and this fixed connection can be for cup jointing, joint etc. the common connection mode of dismantling in this field, first box body 11 and bottom 10 fixed connection in order to form airtight space to deposit the gaseous raw materials of preparation disinfection, if: a solid powder; and the first container 11 forms two independent spaces for storing the reactant in the home sterilization module 100. The push rod 15 pushes against the first cartridge 11 and moves the first cartridge 11 to mix the reactants at both sides of the first cartridge with each other, and the sealing member 17 prevents the reactants from flowing out of the inlet of the receiving part 102. Specifically, the first box 11 divides the household electrical appliance sterilization module 100 into two independent chambers, the two independent chambers are respectively used for storing a first reactant and a second reactant, the rod 15 is assembled in the containing portion 102 from the inlet of the containing portion 102, the end of the rod 15 faces the outlet of the containing portion (the first box 11), after the rod 15 pushes up the first box 11, the first reactant and the second reactant originally in the two independent chambers flow and mix with each other, that is, at this time, the containing portion 102 will be filled with a liquid reactant and/or a liquid reactant product, and the sealing member 17 is arranged to prevent the reactant and/or the reactant product from flowing out from the inlet of the containing portion 102, that is, the reactant and/or the reactant product from leaking out of the household electrical appliance sterilization module 100.

In some embodiments, the accommodating portion 102 may be a chamber with the same caliber, which facilitates processing; in other embodiments, when the mandrel 15 is irregular in shape, the receptacle 102 may need to be adjusted according to the shape of the mandrel 15. In some embodiments, the accommodating portion 102 includes a first protrusion 104 extending along the inner wall of the accommodating portion 102 toward the center of the rod 15, so that the end of the rod 15 abuts against the first protrusion to prevent the rod 15 from moving excessively; specifically, when the end of the cylindrical top rod 15 includes a circular boss, and the boss and the main body of the top rod 15 have different diameters, the accommodating portion 102 includes a first protrusion 104 therein, and the first protrusion 104 extends toward the center of the top rod 15 along the inner wall of the accommodating portion 102 to form an accommodating portion 102 with a smaller diameter in the accommodating portion 102 to accommodate the main body portion of the top rod 15. The end of the top bar 15 can be located at the entrance of the containing part 102 or in the containing part, when the end of the top bar 15 is located at the entrance of the containing part 102, the end of the top bar 15 and the contour of the bottom cover 10 form an integral contour; when the end of the top rod 15 is located in the accommodating part 102 and the accommodating part 102 comprises the first protrusion, the end of the top rod 15 abuts against the first protrusion to provide support for the top rod 15, and meanwhile, the first protrusion prevents the movement distance of the top rod 15 in the accommodating part 102 from exceeding the set movement distance, so that the isolation structure is separated from the preset position; or the top rod 15 may be damaged after excessive movement.

The rod 15 does not contact the first container 11 or interferes with the first container 11 but does not interfere enough with the first container 11 to allow the reactants on both sides of the first container 11 to flow each other before the home sterilization module 100 is not activated. Specifically, in some embodiments, after the mandrel 15 is assembled from the inlet of the accommodating portion 102 to the accommodating portion 102, there is a gap of 1 between the end of the mandrel 15 and the first case 11, the gap is between 1mm and 10mm, so that the mandrel 15 abuts against the first case 11 after moving for a certain distance and jacks up the first case 11, and by providing the gap, a certain buffer space is provided for the mandrel 15, thereby preventing the domestic appliance sterilization module 100 from jacking up the first case 11 without activating the domestic appliance sterilization module 100 in an accidental state of the domestic appliance sterilization module 100. In other embodiments, the end of the top bar 15 abuts against the first box 11 before the home electric sterilization module 100 is started, but the abutting force is not strong enough to lift the first box 11, and at this time, only a small driving force needs to be given to lift the top bar 15 up the first box 11.

EXAMPLE III

As shown in fig. 1 to 6, a household appliance sterilization module 100 includes the sealing structure in the above embodiment, and further includes: the household appliance comprises a bottom cover 10, wherein the side of the bottom cover 10, which is far away from a household appliance inner container 200, comprises a first cavity 101 for containing a first reactant, the bottom cover 10 is fixedly connected with a first box body 11, and the fixed connection mode of the first box body 11 and the bottom cover 10 comprises but is not limited to clamping, sleeving, screwing and the like; the two are fixedly connected to form an accommodating space for accommodating reactants, and the reactants are solid or liquid. The first box body 11 is fixedly connected with the bottom cover 10, and the first box body 11 encapsulates a first reactant in the first chamber 101; the top cover 12 is fixedly connected with the bottom cover 10, and an accommodating space for accommodating a second reactant is formed between the top cover 12 and the first box body 11; at this time, in some embodiments, the bottom cover 10 may be ultrasonically welded to the top cover 12; in other embodiments, the bottom cover 10 and the top cover 12 may be fixed by clamping, sleeving, screwing, bonding, or the like, that is, the top cover 12 and the bottom cover 10 may be fixed by detachable connection or non-detachable connection, and when non-detachable connection is adopted, the sealing performance of the household appliance sterilization module 100 may be ensured. Wherein the receptacle 102 is disposed adjacent to the first chamber 101; the ejector pin 15 is forced to act on the first container 11 to at least partially separate the first container 11 from the bottom cover 10, so that the first reactant and the second reactant are mixed to generate the volatile for sterilization.

The closed space formed by the bottom cover 10 and the first box body 11 is used for storing a first reactant; the first box body 11 and the top cover 12 form a closed space for storing a second reactant; the ejector pin 15 ejects the first box body 11 to mix the first reactant and the second reactant to generate the sterilizing gas. The first reactant and the second reactant can be any raw materials capable of producing a gas for disinfection, and in some embodiments, the second reactant is an acidic liquid, such as hypochlorous acid and/or hydrochloric acid, and the first reactant is a solid or a solid powder (in order to mix the first reactant with the second reactant after the home sterilization module 100 is activated, the solid or the solid powder fills the first chamber 101 as much as possible or the liquid level of the second reactant reaches the position of the chamber where the first reactant is located), and the fixed powder is generally a chlorate or chlorite powder, so as to mix to generate a chlorine dioxide gas; in other embodiments, the first reactant may be provided as an acidic liquid and the second reactant may be provided as a solid powder, which facilitates the mixing of the liquid reactant flowing from the first chamber 101 with the second reactant. In other embodiments, the first reactant and the second reactant may both be liquids, and only the reaction of the two reactants to generate the sterilizing gas is required. It should be noted that the substance formed by the reaction of the first reactant and the second reactant preferably does not contain a precipitate, so as to prevent the detection accuracy of the turbidity sensor 16 from being affected when the turbidity sensor 16 is included. In other embodiments, the first reactant is barium oxide powder and the second reactant is sulfuric acid, which are mixed to produce ozone gas. It should be noted that, during the chemical preparation of ozone, precipitates are often generated, which may increase the burden of the home appliance sterilization module 100, and therefore, the sterilization gas used in the home appliance sterilization module 100 is preferably chlorine dioxide gas.

When the second reactant is liquid, in order to ensure that the first container 11 can be at least partially separated from the bottom cover 10, the second reactant can easily flow into the first chamber 101, and the liquid level of the second reactant in the top cover 12 at least exceeds the peripheral contour of the first container 11, so that the second reactant can enter the sealed space formed by the first container 11 and the bottom cover 10 after the first container 11 is at least partially separated from the bottom cover 10.

In other embodiments, when the domestic sterilizing module 100 is horizontally suspended on the top of the inner container, the level of the second reactant at least does not exceed the position of the overall peripheral contour of the first box 11, and preferably the level of the second reactant fills the overall top cover 12, so as to ensure that the second reactant and the first reactant can be easily mixed.

The bottom cover 10 includes a first chamber 101 for accommodating a first reactant, the first chamber 101 has a certain depth for storing the first reactant, the first chamber 101 may be configured in any shape, and in some embodiments, the first chamber 101 extends to the side away from the inner container of the appliance casing. The mounting structure further comprises a first box body 11 which is fixedly connected with the bottom cover 10; before the household appliance sterilization module 100 is used, the first box body 11 encloses the first reactant in the first chamber 101 to prevent the first reactant from flowing out of the first chamber 101. Specifically, the first container 11 is detachably connected to the bottom cover 10, the detachable connection is different from the fixed connection between the bottom cover 10 and the top cover 12, and the fixed connection between the first container 11 and the second container is easily removed under the action of external force. The top rod 15 moves towards the first container 11 to at least partially separate the first container 11 from the bottom cover 10, so that the second reactant and the first reactant are mixed, and it should be noted that after the at least partially separated top rod 15 abuts against the first container 11, the first container 11 can still be hung on the containing portion 102 of the bottom cover 10, or can directly fall down.

In some embodiments, the bottom cover 10 further includes a receiving portion 102 for placing the top bar 15, and the receiving portion 102 is a movement space of the top bar 15; the containing part 102 is arranged near the first chamber 101, the top rod 15 abuts against the first box body 11 sealing the first chamber 101 after moving in the containing part 102 and makes the first box body 11 partially separated from the first chamber 101 (i.e. the first box body 11 is still kept on the first chamber 101), so that two reactants in a separated state in the containing space are mixed with each other to generate volatile matters for sterilization; at this time, the accommodating part 102, the stem 15 and a sealing member (e.g., a sealing ring fitted on the stem 15) together form a sealed space to prevent the raw material for preparing volatile or the product of the raw material from flowing out of the accommodating part 102. In some embodiments, the bottom cover 10 may be ultrasonically welded to the top cover 12; in other embodiments, the bottom cover 10 and the top cover 12 may be fixed by clamping, sleeving, screwing, bonding, or the like, that is, the top cover 12 and the bottom cover 10 may be fixed by detachable connection or non-detachable connection, and when non-detachable connection is adopted, the sealing performance of the household appliance sterilization module 100 may be ensured. The closed space formed by the bottom cover 10 and the first box body 11 is used for storing a first reactant; the first box body 11 and the top cover 12 form a closed space for storing a second reactant; the ejector pin 15 ejects the first box body 11 to mix the first reactant and the second reactant to generate the sterilizing gas.

In some embodiments, the accommodating portion 102 is located near the first chamber 101, and the rod 15 pushes against the first box 11 after moving a distance in the accommodating portion 102 to jack up the first box 11; in some embodiments, the accommodating portion 102 is disposed inside the first chamber 101, and an accommodating space for the first reactant is formed between the accommodating portion 102 and the first chamber 101, the accommodating portion 102 extends along the extending direction of the first chamber 101 to the side away from the tank liner 200, the shape and size of the accommodating portion 102 are similar to the shape and size of the top bar 15, and a gap exists between the end of the top bar 15 and the first box 11 in an initial state, so that the top bar 15 can abut against the first box 11 after moving a small distance after receiving an external force, and a gap is formed between the first box 11 and the bottom cover 10. In other embodiments, the accommodating portion 102 is disposed at the peripheral edge (not shown) of the first chamber 101, the shape and size of the accommodating portion 102 are similar to the shape and size of the rod 15, and the accommodating portion 102 extends toward the extending direction of the first chamber 101; the end of the top bar 15 has a gap with the outer contour of the first container 11 initially, and after the top bar 15 is stressed, the end of the top bar 15 abuts against the outer contour of the first container 11, so that the first container 11 is partially separated from the bottom cover 10 after being stressed. In order to make the top rod 15 easily contact with and lift up the first box 11, at this time, a contact part matching with the top rod 15 may be disposed on the outer contour of the first box 11, so as to lift up the first box 11.

When volatile chlorine dioxide gas for sterilization is contained in the containing space, the chlorine dioxide gas needs to be loaded in the gel substances, and at the moment, the turbidity sensor 16 detects the change of the color of the gel in the containing space to obtain the residual amount of the chlorine dioxide gas; when the accommodating space is filled with raw materials for preparing volatile matters, the color change of liquid or gel in the accommodating space is detected by the turbidity sensor 16 so as to obtain the residual amount of the volatile matters.

For convenience of processing, the bottom cover 10 may be directly made of a transparent material so that the turbidity sensor 16 detects a color change in the accommodating space.

In order to control the ventilation amount of volatile matters in the household appliance sterilization module 100, the household appliance sterilization module further comprises a ventilation film 13, the ventilation film 13 is covered on the ventilation hole of the top cover 12 along the outline of the top cover 12 in a sealing manner, and the ventilation hole can be set to be in any shape and any position; the setting of ventilated membrane 13 along the profile of top cap 12 has been promptly guaranteed the leakproofness between ventilated membrane 13 and the top cap 12, prevents to have the gap between ventilated membrane 13 and the top cap 12, leads to the volatile substance not to get into the household electrical appliances inner bag promptly through ventilated membrane 13. The gas permeable membrane 13 is a gas permeable and water impermeable material to prevent the outflow of the reactant and/or the reactant product, and in this embodiment, the processing is convenient and gas permeable and water impermeable can be ensured. Because the breathable film is soft and easy to damage, in some embodiments, the breathable film module further comprises a second box body 14, the breathable film 13 is pressed on the top cover 12 by the second box body 14, and at the moment, the second box body 14, the top cover 12 and the bottom cover 10 form a consistent overall outline, so that the integrity and the attractiveness of the household appliance sterilization module can be ensured; in addition, the second container 14 presses the air permeable membrane 13 on the top cover 12, which can prevent the air permeable membrane 13 from decreasing in sealing property after long-term use and forming a gap with the top cover 12. The second box 14 further comprises a plurality of air holes to facilitate air entering the household appliance box.

The gas-permeable membrane 13 is made of a gas-permeable and water-impermeable material, and may be a gas-permeable membrane (such as a PE membrane, a PUW membrane, etc.), silica gel, non-woven fabric, etc., which can facilitate the gas of volatile substances to pass through, and can prevent liquid from overflowing the household appliance sterilization module 100, and in addition, the gas-permeable membrane 13 can prevent dust outside the sterilization module 100 from entering the household appliance sterilization module. Because different breathable films 13 have different breathable rates, the breathable films 13 can be selected according to the volume of the household appliance, so as to adjust the breathable amount of the volatile matters in the same time period.
