Title: Intelligent sterilization, deodorization and carbon-releasing reduction garbage bin

Description:
TECHNICAL FIELD 
     The present disclosure relates to the field of garbage, and more particularly to an intelligent sterilization, deodorization and carbon-releasing reduction garbage bin. 
     BACKGROUND 
     Organic garbage containing moisture or water (also known as kitchen garbage or wet garbage) is easy to generate odor during stacking, contains a large number of harmful or pathogenic microorganisms, and releases a large amount of carbonaceous substances. In order to reduce the amount of odor generation and inhibit activities of microorganisms during the stacking of garbage, a patent publication document CN211418370U discloses a garbage bag and its holding and attachment device. In this document, the garbage bag filters out water or liquid components contained in the garbage to reduce activity intensities of microorganisms, thereby achieving purposes of reducing the generation of odor and inhibiting activities of microorganisms. However, this kind of garbage bag only filters out most of the water in the garbage, efficiencies of deodorization and microorganism inhibition are relatively low, and thus cannot achieve comprehensive multiple effects of sterilization, deodorization and carbon-releasing reduction. In addition, the patent publication document CN211418370U (with an assignee same as that of the present disclosure) discloses a liquid storage cavity in a garbage bin is arranged under a movable plate to separate an accommodating cavity and a liquid storage cavity of the garbage bag and support the weight of the garbage in the accommodating cavity. However, this design would significantly increase the manufacturing difficulty, and when in use, the movable plate at the bottom of the garbage bin must be turned up in order to place the liquid storage cavity of the garbage bag under the movable plate in advance, which would cause great inconvenience or trouble. 
     SUMMARY 
     Aiming to the above problems in the related art, the present disclosure proposes an intelligent sterilization, deodorization and carbon-releasing reduction garbage bin. 
     Technical solutions provided by the present disclosure are as follows. 
     An intelligent sterilization, deodorization and carbon-releasing reduction garbage bin includes: a bin body, a bin cover, a solution storage chamber, and a spray head. The bin cover is disposed on the bin body. The solution storage chamber is connected to the spray head. The spray head is set up on a wall of the bin body or on the bin cover through a connection structure. 
     It is noted that, the garbage bin of the present disclosure generally is used together with a garbage bag or an inner bucket. The garbage bag is placed in the bin body and for accommodating garbage. The inner bucket also is placed in the bin body and for accommodating garbage. The garbage bag and the inner bucket may be used at the same time, i.e., the inner bucket is placed in the bin body and the garbage bag is sleeved in the inner bucket. 
     In the intelligent sterilization, deodorization and carbon-releasing reduction garbage bin of the present disclosure, the solution storage chamber and the spray head are disposed through the connection structure, the solution storage chamber is used to store a mixture solution with effects of sterilization, deodorization and carbon-releasing reduction, and the spray head is used to spray the mixture solution stored in the solution storage chamber. When in use, the garbage bag, or the inner bucket, or both the garbage bag and the inner bucket sleeved together is/are placed in the bin body, and then the solution sprayed from the spray head can enter into the garbage bag or the inner bucket through an opening on the garbage bag, or through a groove/hole on the bin body or directly. When in use, garbage such as kitchen waste are thrown into the inner bucket or the garbage bag, and then the spray head is used to spray a sterilization and deodorization solution stored in the solution storage chamber towards the garbage to greatly kill harmful microorganisms and reduce the production of odor and the emission of carbon dioxide and methane under the effect of sterilization and deodorization solution. 
     A molding groove may be disposed at the bottom of the intelligent sterilization, deodorization and carbon-releasing reduction garbage bin. The molding groove is located inside the bin body. When cooperating with the garbage bag disclosed in the patent publication document CN211418370U or the inner bucket of the present disclosure, the molding groove can accommodate a liquid storage cavity of one of the garbage bag and the inner bucket, and bin bottom (inclined) plates on both sides of the molding groove can support the weight of the garbage in the bin body, so that most of water in the garbage can be automatically filtered out by gravity continuously and thereby playing a role of slowing down fermentation, decay and mildew. Moreover, when using an intelligent control system on a circuit board, as needed or in automatic timed and quantitative manner, to timely spray the mixture solution with effects of sterilization, deodorization and carbon-releasing reduction into the garbage bag or the inner bucket, it can further enhance the effects of sterilization, deodorization and carbon-releasing reduction on the garbage in the bag or the inner bucket. In addition, when the mixture solution penetrates downwardly into the liquid storage cavity, it can play an inhibition role again on parts with the most potential of fermentation, decay and mildew. Furthermore, the cavities at the bottom of the bin body and a dual gap between the garbage bag and/or the inner bucket and the bin body form two spaces for blocking air heat conduction, which can further reduce the process of fermentation, decay and mildew caused by heat. A combined action of multiple automatic sterilization, deodorization and carbon-releasing reduction cleverly combined together can effectively inhibit activities of microorganisms in fermentation, decay and mildew of organic substances, and yield unpredictable multiple effects. 
     Since the intelligent sterilization, deodorization and carbon-releasing reduction garbage bin can be used together with the garbage bag disclosed in the patent publication document CN211418370U, and the garbage bag disclosed in the patent publication document CN211418370U has a liquid storage cavity, therefore the bottom of the bin body is disposed with the molding groove, and the molding groove is used to receive the liquid storage cavity of the garbage bag or the inner bucket. Due to the existence of the molding groove, it can position the liquid storage cavity to avoid the liquid in the liquid storage cavity mixing with the organic waste in the bag again. The bin bottom (inclined) plates on both sides of the molding groove, together with clamping of the bin cover and holding of hook tabs, can make the garbage in the garbage bag better supported and secured in the bin body. 
     The molding groove may be a linear groove, or a S-shaped groove, or a Z-shaped groove. Non-linear groove can increase the length of the molding groove as much as possible within limited length and width of the bottom of the bin body, thereby accommodating the liquid storage cavity of the garbage bag as much as possible. 
     Because the molding groove is disposed at the bottom of the bin body, and the liquid storage cavity of the garbage bag is located in the molding groove, garbage in the accommodating cavity of the garbage bag is mainly supported by the bin bottom plates of the bin body. This design can prevent the garbage bag from cracking due to excessive weight of the garbage in the bag. 
     The solution storage chamber may be a portion of the bin body, or may be an individual solution storage chamber additionally disposed inside or outside the bin body through the connection structure. 
     In an embodiment, cavities are defined at the bottom of the bin body and located outside the bin body, and the cavities are arranged along peripheral edges of the molding groove. 
     Due to the cavities are disposed outside the bin body and arranged along the peripheral edges of the molding groove, and the cavities have a certain heat insulation effect, it can reduce or suppress heat convection between air outside the bin body and liquid inside the molding groove, so that in high-temperature weather, it can play a certain heat insulation effect on the liquid inside the molding groove and slow down the process of liquid stinking. 
     In an embodiment, the garbage bin further includes a hanging hook. The hanging hook is detachably disposed on a bin wall of the bin body, and the solution storage chamber is detachably disposed on the hanging hook. 
     The role of disposing the hanging hook is to install the solution storage chamber, and the solution storage chamber is hung on the bin wall of the bin body by the hanging hook, such design is convenient to remove the solution storage chamber from the bin body at any time according to the need. The hanging hook is used for installation, on one hand, it is easy to disassemble at any time, and on the other hand, it would not damage the garbage bag. Compared with traditional fixing methods such as fixed type, Velcro type and snap type, installation through the hanging hook is more convenient and faster or reliable. Moreover, it is very convenient for cleaning, repair and maintenance of the garbage bin and the solution storage chamber. For example, when the automatic spraying function of the solution storage chamber is failed, the solution storage chamber can be easily taken down and sent directly to a maintenance point for repair, which can greatly avoid the consumption of manpower and time of on-door repair. 
     In an embodiment, the garbage bin further includes an electric pump, a battery, and a control circuit board a chip. The solution storage chamber is connected to the spray head through the electric pump. The electric pump, the battery and the control circuit board are disposed on the solution storage chamber. The battery and the electric pump are electrically connected to the control circuit board. 
     The role of the battery and the electric pump is to pump the sterilization and deodorization mixture solution stored in the solution storage chamber to the spray head, and then the mixture solution is sprayed out by the spray head. The control circuit board is used to control the battery and the electric pump, and the control circuit board can be programmed according to a need to regulate and control the battery and the electric pump, and a spraying amount and a spraying time of the sterilization and deodorization solution can be set through programming. A remote controller may be provided to control functions of the control circuit board wirelessly. The remote controller can also be responsible for controlling a movement of the garbage bin through a power device and a moving device disposed on the garbage bin. 
     In addition, a key-press board may be disposed on the control circuit board. The key-press board is made of a soft rubber. The key-press board is disposed with an end hole for clamping a USB interface, and meanwhile one side of the key-press board is disposed with an end cover for sealing the end hole. Moreover, the key-press board is disposed soft column thereon, and touch keys on the control circuit board can be pressed through the soft columns. The existence of the key-press board can play a good role in waterproofing the control circuit board and effectively protect the keys from damage caused by heavy objects. 
     In an embodiment, the bin body is disposed hook tabs thereon. 
     The role of the hook tabs is to hook a garbage bag through holding holes on the garbage bag, so as to play a role of holding the garbage bag and thereby avoid the garbage bag from slipping into the bin body when throwing garbage into the garbage bag. 
     The hook tabs are specifically disposed at a bin opening of the bin body and located outside the bin body, so that when taking out the garbage bag, it can avoid unpleasant or uncomfortable feeling caused by direct hand contact with the garbage inside the bag. 
     In an embodiment, the bin cover includes a frame and a cover plate. One end of the cover plate is rotatably mounted on the frame. Moreover, devices such as a sensor and a motor which can automatically open and close the cover plate can be disposed on the frame. 
     Specifically, the frame is used to clamp with the bin mouth of the bin body, in addition to fixing the bin cover to prevent sliding, it can clamp the garbage bag tightly. One end of the cover plate is rotatably engaged with the frame through a pin shaft, and the role of the cover plate is used to close the bin body. 
     In an embodiment, a nozzle of the spray head is inclined towards a bin bottom side of the bin body. 
     Since the nozzle of the spray head faces towards the bin bottom side of the bin body, it can ensure that the sterilization and deodorization solution sprayed from the spray head can be sprayed towards the garbage effectively. 
     Specifically, the spray head may be an atomization sprayer, and liquid leaving the nozzle of the spray head is atomized sterilization and deodorization solution. For such operation, it can make the atomized sterilization and deodorization solution fully enter into the garbage bin, and moreover atomized droplets can adsorb particles with microorganisms as well as dust in the air in the bin body, which facilitates the particles and dust in the garbage to form larger particles and then fall into the garbage bag, thereby avoiding particles with microorganisms and dust to be raised to pollute external environment. 
     In an embodiment, the garbage bin further includes a spray seat. The spray seat is disposed on the solution storage chamber, and the spray head is clamped/mounted on the spray seat. 
     Specifically, the spray seat is mainly used to clamp and fix the spray head, and may further be equipped with a liquid guide plate, a three-way groove, a wiring groove serving as pipe groove as well as wire groove, and a support block. Therefore, the spray seat may have multiple functions such as positioning and supporting a lid of the solution storage (spraying) chamber. 
     In an embodiment, the spray seat is disposed an arc-shaped liquid guide plate thereon. 
     In particular, the spray seat is provided with a clamping hole, the spray head is clamped in the clamping hole of the spray seat, and the liquid guide plate is arranged at a mouth on one side of the clamping hole. When in use, the liquid guide plate can be used to pass through a bag hole of a wall of the garbage bag. In the process of spraying atomized liquid, the liquid guide plate can guide the liquid to ensure that the atomized liquid is sprayed towards the bottom of the garbage bag through the liquid guide plate, and meanwhile in the process of spraying atomized liquid, some atomized liquid will leak from the spray head, the existence of the liquid guide plate can collect the leaked liquid and introduce it into the garbage, thereby avoiding the leaked liquid to be left between the bin wall of the bin body and the garbage bag, and also playing the role of positioning the bag hole of the garbage bag. 
     Beneficial effects can be achieved by the present disclosure are that: by disposing the garbage bag and/or the inner bucket with the liquid storage cavity, the molding groove, the solution storage chamber, the spray head and the intelligent control device, the solution storage chamber is used to store the sterilization and deodorization solution, and the spray head is used to spray out the sterilization and deodorization solution stored in the solution storage chamber; which can filter out water from garbage uninterruptedly and spray a special liquid with effects of sterilization, deodorization and carbon-releasing reduction to the garbage as needed or in an automatic timed and quantitative manner. The special liquid penetrates downwardly into the liquid storage cavity to function again. The cavities at the bottom of the bin body and gaps between the garbage bag and/or the inner bucket and the bin body form dual air heat conduction blockings. The combined effect of multiple ingenious combinations of automatic sterilization and deodorization and carbon-releasing reduction can effectively kill or inhibit activities of microorganisms in fermentation, decay and mildew of organic substances, kill harmful microorganisms, and reduce the generation of odor and the emission of carbon dioxide and methane.
