The volatile matter in the sterilization module body 1 is finished products or prepared on site. Specifically, the sterilization module body 1 can be used for directly storing sterilization gas, but the amount of sterilization gas which can be stored is limited due to the limited internal space, and if the household appliance sterilization module 100 is used, the household appliance sterilization module needs to be frequently replaced in a short time, which affects user experience; in this case, the sterilizing gas may be chlorine dioxide or ozone. In order to obtain the household appliance sterilization module 100 with longer service life to improve user experience, the sterilization module body 1 can be used for storing raw materials for preparing the sterilization gas, and when the household appliance sterilization module 100 needs to be used, the raw materials for preparing the sterilization gas are triggered to react to prepare a large amount of sterilization gas.

In some embodiments, the sterilization module body 1 may be partially made of a breathable film during the original processing, which, although the processing process is complicated, solves the problem of the sealability between the breathable film and the ventilation portion where the first ventilation hole 112 is located.

When this household electrical appliances module 100 that disinfects selects on-the-spot preparation disinfection gas to obtain a large amount of disinfection gas, module body 1 that disinfects includes: a bottom cover 10, wherein the side of the bottom cover 10, which is far away from the household appliance liner 200, comprises a first chamber 101 for storing a first reactant; the first chamber 101 has a certain depth for storing a first reactant, the first chamber 101 can be configured in any shape, and in some embodiments, the first chamber 101 extends to the side away from the household appliance cabinet inner container 200; the bottom cover 10 is fixedly connected with the top cover 12, and a containing cavity is formed between the bottom cover 10 and the top cover 12 to contain reactants. A first cartridge 11 for enclosing a first reactant in the first chamber 101; the top cover 12 is fixedly connected with the bottom cover 10, and a storage space for storing a second reactant is formed between the top cover 12 and the first box body 11; under the action of external force, the first container 11 is at least partially separated from the bottom cover 10, so that the two reactants in the isolated state in the home sterilization module 100 are mixed with each other to generate the volatile for sterilization. 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 in a detachable or non-detachable manner, and when non-detachable connection is adopted, the sealing performance of the household appliance sterilization module 100 may be ensured; the top cover 12 stores a second reactant therein; the first box body 11 is used for packaging a first reactant in the first chamber 101, so that the first reactant and a second reactant do not circulate before the home appliance sterilization module 100 is started, and the first box body 11 can be initially covered or sleeved on the bottom cover 10 or the first box body 11 is of a flip structure or a hinge structure; under the action of external force, the first container 11 is at least partially separated from the bottom cover 10, so that the first reactant and the second reactant are mixed, and volatile substances for disinfection are generated and flow out from the ventilation part on the sterilization module body 1. The external force can be provided by a user or provided by the external force, namely, the ejector rod 15 contacts the first box body and partially separates the first box body 11 from the bottom cover 10, and at this time, the first box body 11 does not fall (hang on the first chamber 101), and the detection instrument cannot be influenced to detect the reactant product (such as the color of chlorine dioxide gas) in the sterilization module body 1; if the detection is not required, the first container 11 can be completely separated from the bottom cover 10. Since the sterilization substance in the household appliance sterilization module 100 is a gas, the top cover 12 includes a ventilation portion, which may be set to any shape and any position, and in some embodiments, the ventilation portion is a ventilation film 13; in other embodiments, the top cover 12 includes a plurality of first ventilation holes 112, the first ventilation holes 112 can be disposed in any shape and any position, the first ventilation holes 112 include a gas permeable membrane, and the gas permeable membrane is hermetically covered on the top cover 12 at the area of the first ventilation holes 112 to prevent the reactants and/or the reactant products from flowing out.

When the sterilization gas is a finished product of sterilization gas, the sterilization module body 1 further includes a ventilation area and a sealing layer (not shown), and the sealing layer covers the ventilation area when the home appliance sterilization module 100 is not activated. That is, if the sterilizing gas is the finished product, the sterilization module body 1 is not breathable before being used, but needs a breathable area to allow the sterilizing gas to enter the household appliance box body after being used. Therefore, a plurality of vent holes can be formed in the top cover 12 or the bottom cover 10, and a sealing layer can be covered on the plurality of vent holes, the sealing layer can be uncovered and punctured before use, or the sealing layer is a cover body covered on the breathable part, and the sealing layer can be detached when needed. The vent may also be a gas permeable membrane. In some embodiments, a gas permeable region and a sealing layer may be disposed on both the top cover 12 and the bottom cover 10, and the sealing layer may be broken to improve the communication between the sterilizing gas and the gas in the household appliance cabinet.

If the sterilizing gas is prepared on site in real time, the sterilizing module body 1 includes an independent space which is at least used for storing the reaction raw materials of the sterilizing gas. In some embodiments, if chlorine dioxide gas is produced on-site, sterilization module body 1 includes two separate spaces for holding raw materials or other materials. For example, when two separate spaces are included, one space is used to store a first reactant and the other space is used to store a second reactant; for example, one space contains an acidic liquid, such as hypochlorous acid and/or hydrochloric acid, etc., and the second space contains a solid powder, typically chlorate or chlorite powder; it will be appreciated that the acidic liquid may be disposed in the second space and the solid powder may be disposed in the first space. It should be understood that the substance stored in the first space and the second space may be any substance that can combine to generate chlorine dioxide, and the state of the substance is not limited. For example, chlorine dioxide gas can be generated by reacting an acid solution with an aqueous sodium chlorite solution.

It is to be noted that when the preparation of the sterilizing gas is selected, the prepared sterilizing gas is preferably chlorine dioxide; because ozone causes precipitation during chemical preparation, the precipitation affects the detection accuracy of the turbidity sensor 16. Thus, reference in this embodiment to the preparation of a sterilizing gas is to be taken as the reference to chlorine dioxide gas.

In some embodiments, the bottom cover 10 further comprises a sealing part 102 for placing the top bar 15, wherein the sealing part 102 is a movement space of the top bar 15; the sealing part 102 is arranged near the first chamber 101, the top rod 15 collides with the first box body 11 sealing the first chamber 101 after moving in the sealing 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 the two reactants in the isolated state in the accommodating space are mixed with each other to generate volatile matters for sterilization; at this time, the sealing part 102, the plunger 15 and the sealing member (e.g., a sealing ring fitted on the plunger 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 sealing 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.

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. In addition, the first container 11 can be a hinge structure or a flip structure, so that the first container 11 initially forms a closed space with the bottom cover 10, when an external force is applied, the first container 11 and the bottom cover 10 form a gap for the reactants to flow in or out, and at this time, the first container 11 is kept on the bottom cover 10, and the measurement accuracy of the turbidity sensor 16 cannot be affected by the falling.

In some embodiments, the sealing portion 102 includes a boss (not shown) extending along the inner wall of the sealing portion 102 toward the center of the stem 15 to form a smaller diameter sealing portion 102 in the sealing portion 102 to accommodate the main body portion of the stem 15. The end of the jack 15 can be located at the entrance of the sealing part 102 or in the sealing part, when the end of the jack 15 is located at the entrance of the sealing part 102, the end of the jack 15 forms an integral contour with the contour of the bottom cover 10; when the end of the push rod 15 is located in the sealing part 102 and the boss is included in the sealing part 102, the end of the push rod 15 abuts against the boss to provide support for the push rod 15, and at the same time, the boss prevents the push rod 15 from moving excessively to completely separate the first container 11 from the bottom cover 10.

The bottom cover 10 includes a sealing portion 102 for receiving the lift pin 15, at this time, the lift pin 15 is directly mounted on the bottom cover 10, and the lift pin 15 moves in the sealing portion 102 to partially separate the first container 11 from the bottom cover 10; 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.

In some embodiments, the protrusion 111 extends away from the appliance liner 200, wherein the opening of the protrusion 111 is larger than the opening of the sealing portion 102, and the protrusion 111 initially hangs on the sealing portion 102. In other embodiments, the protrusion 111 extends toward the side close to the household appliance liner 200, at this time, the opening of the protrusion 111 is smaller than the opening of the sealing portion 102, and the protrusion 111 is initially sleeved on the sealing portion 102. When the first container 11 is stressed, the first container 11 is lifted, but the first container 11 still can be kept on the bottom cover 10 and cannot fall down due to the existence of the protrusion 111, and at this time, a gap is formed between the first container 11 and the bottom cover 10, so that the reactant can slowly react; in addition, when the turbidity sensor 16 is included, the first container 11 is held on the bottom cover 10, so that the detection accuracy of the turbidity sensor 16 can be prevented from being affected by the falling thereof.

In order to prevent the sterilizing gas in the household appliance sterilization module 100 from remaining in the household appliance cabinet after the sterilizing gas is used up, it is necessary to indicate the remaining amount of the sterilizing gas in the household appliance sterilization module 100. In some embodiments, the bottom cover 10 further includes a second cavity 103 on a side close to the household appliance inner container 200, and at least the second cavity 103 is made of a transparent material, and the second cavity 103 is used for accommodating the turbidity sensor. The second chamber 103 is shaped and sized according to the size and shape of the turbidity sensor 16 so that the turbidity sensor 16 can be stably placed in the second chamber 103.

In order to ensure the detection accuracy of the turbidity sensor 16 and ensure that the turbidity sensor 16 maximally contacts the volatile matter in the accommodating space, the second chamber 103 is preferably set as a recess extending from the bottom cover 10 to the side away from the household appliance inner container 200, at this time, the second chamber 103 is located in the accommodating space formed by the bottom cover 10 and the top cover 12, that is, the substance in the accommodating space is set around the turbidity sensor 16, so as to ensure that the turbidity sensor 16 rapidly detects the color change in the accommodating space. 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.

The bottom cover 10 is fixedly connected with the top cover 12, an accommodating cavity is formed between the bottom cover 10 and the top cover 12 to accommodate reactants, before the first reactant and the second reactant are not mixed, the second reactant is stored in the top cover 12, and the second reactant and the first reactant are separated into two independent spaces through an isolation structure (for example, a first box body 11 is independently arranged to cover the first cavity 101); the second chamber 103 is located remotely from the first chamber 101 so that when the second reactant is mixed with the first reactant, the turbidity sensor 16 is in a region of uniform concentration of the mixed reactants; specifically, since the turbidity sensor 16 is disposed away from the first chamber 101 storing the first reactant, when the second reactant is mixed with the first reactant, the color inside the first chamber 101 and near the first chamber 101 is darker (the volatile concentration is high), and the color away from the first chamber 101 is lighter (the volatile concentration is low); when the volatile matter volatilizes for a period of time, the concentration of the volatile matter tends to be balanced, namely, the color of the accommodating cavity tends to be consistent. Therefore, in order to ensure the accuracy of the measured concentration of the sterilizing gas, the turbidity sensor 16 is located remotely from the first chamber 101.

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.

It should be understood that the sterilizing gas in this embodiment is a gas having a distinct color, such as chlorine dioxide gas, which is dispersed in the gel-like substance, and the color of the gel changes as the chlorine dioxide gas volatilizes, and the color change of the gel is detected by the turbidity sensor to reflect the remaining amount of the chlorine dioxide gas.
