Description

Technical Field

[0001] This application relates to the field of kitchenware technology, and in particular to a kitchenware sterilizer. Background Technology

[0002] As living standards improve, people are paying more and more attention to the hygiene of various utensils in the kitchen that come into contact with food. Knife sterilizers can store knives, cutting boards, chopsticks, etc., and also have ultraviolet sterilization and drying functions, so the market demand is increasing.

[0003] Kitchenware sterilizers using this technology typically employ simple air inlet structures without effective insect and dust prevention measures. This allows dust and insects to easily enter the device, affecting the normal operation of the heating components and even interfering with the sterilization effect. While some devices use denser air inlets to prevent insects from entering, this method reduces air intake efficiency and fails to effectively filter fine particulate matter in the air. Furthermore, because sterilizers are usually designed with open structures for easy handling of tableware, bacteria in the air can easily re-adhere to the sterilized kitchenware surfaces after the device has finished running, thus reducing the overall sterilization effect.

[0004] Therefore, how to achieve efficient insect and dust prevention while ensuring air intake efficiency, and how to inhibit airborne bacteria from re-attaching to the surface of kitchen utensils after the equipment has finished operating, has become an urgent technical problem to be solved. Utility Model Content

[0005] Therefore, it is necessary to provide a kitchenware sterilizer to address the issue of how to achieve efficient insect and dust prevention while ensuring air intake efficiency.

[0006] This application provides a kitchenware sterilizer, which includes a main body and an electric grid assembly. The main body includes a shell with a sterilization space and a fan assembly disposed within the sterilization space. The shell includes an air inlet, and the fan assembly drives outside air to enter the sterilization space through the air inlet. The electric grid assembly is connected to the shell and disposed at the air inlet. The electric grid assembly includes a first mesh electrode and a second mesh electrode arranged at intervals along the direction of air flow through the air inlet, and an electric field is formed between the first mesh electrode and the second mesh electrode.

[0007] In the technical solution of this application embodiment, an electric grid component is provided at the air inlet of the outer casing. The electric grid component includes a first mesh electrode and a second mesh electrode arranged sequentially at intervals along the direction of air flow through the air inlet. An electric field is formed between the first mesh electrode and the second mesh electrode. When the outside air is blown into the sterilization space through the air inlet under the action of the fan component, it passes through the electric field formed by the first mesh electrode and the second mesh electrode. This causes the dust particles in the air to be polarized in the electric field and adsorbed onto the electric grid component. At the same time, the electric grid component can also prevent insects from entering the sterilization space through the air inlet by electric shock, thereby improving the cleanliness of the sterilization space.

[0008] In some embodiments, the power grid assembly further includes a voltage regulating device connected to at least one of the first mesh electrode and the second mesh electrode to regulate the voltage between the first mesh electrode and the second mesh electrode. By providing the voltage regulating device, the electric field strength between the first mesh electrode and the second mesh electrode can be controlled as needed to meet the requirements under different operating conditions.

[0009] In some embodiments, both the first and second mesh electrodes are provided with multiple perforated gaps, with the perforated gaps of the electrode serving as the negative electrode being larger than those of the electrode serving as the positive electrode. This design allows the positive electrode of the first and second mesh electrodes to have a larger area for adsorbing micro-dust, while the larger perforated gaps of the negative electrode reduce the wind resistance generated by the grid components, thereby increasing the air intake of the kitchen sterilizer.

[0010] In some embodiments, the power grid assembly further includes a mounting box connected to the housing, comprising a first plate and a second plate spaced apart from each other, and a through hole penetrating the first plate and the second plate; a first mesh electrode is disposed on the first plate and covers the through hole, and a second mesh electrode is disposed on the second plate and covers the through hole. The mounting box provides mounting space for the first mesh electrode and the second mesh electrode, which helps to improve the structural consistency of the first mesh electrode and the second mesh electrode and reduce the installation error between the first mesh electrode and the second mesh electrode.

[0011] In some embodiments, the mounting box further includes a plurality of third plates connecting the first plate and the second plate. The first plate, the second plate, and the plurality of third plates together form a receiving space, and the first mesh electrode and the second mesh electrode are both disposed within the receiving space. This design can utilize the receiving space to provide a stable operating environment for the power grid components, reducing the risk of external environmental factors affecting the operation of the power grid components.

[0012] In some embodiments, at least one of the plurality of third plates is provided with a power port, which connects the receiving space and the sterilization space. The provision of the power port can provide a good installation environment for the grid assembly, allowing other structures in the grid assembly, except for the first mesh electrode and the second mesh electrode, to be installed in the sterilization space and connected to the first mesh electrode and / or the second mesh electrode in the receiving space through the power port.

[0013] In some embodiments, the main body further includes a baffle plate disposed within the sterilization space, dividing the sterilization space into a first sub-space and a second sub-space. The baffle plate is provided with an air outlet that connects the first sub-space and the second sub-space. The first sub-space is used to store kitchen utensils, while the fan assembly and the electrical grid assembly are disposed in the second sub-space. An air inlet is provided on the portion of the outer casing corresponding to the second sub-space. By dividing the sterilization space into a first sub-space for storing kitchen utensils and a second sub-space for housing the fan assembly and the electrical grid assembly using the baffle plate, the transfer of moisture that may be present in the first sub-space to the second sub-space can be prevented, providing a more stable working environment for the fan assembly and the electrical grid assembly.

[0014] In some embodiments, the fan assembly includes a fan body and a heating device, with an electrical grid assembly disposed between the fan body and the air inlet, and the heating device disposed at the output end of the fan body. This design allows the heating device to heat the air output from the fan body, generating hot air which is then blown into the sterilization space, further improving the removal efficiency of moisture in the sterilization space and enhancing the sterilization effect and efficiency of the kitchenware sterilizer.

[0015] In some embodiments, the kitchenware sterilizer also includes a dust concentration sensor, which is communicatively connected to the electrical grid assembly and is located on the side of the housing facing away from the sterilization space. By using the dust concentration sensor to monitor the external environment, the kitchenware sterilizer can adjust the operating state of the electrical grid assembly according to the dust concentration in the external environment, thus balancing the dust removal effect with energy efficiency.

[0016] In some embodiments, the kitchenware sterilizer also includes a negative ion generator, which is communicatively connected to the fan assembly and used to release negative ions into the sterilization space. By setting the negative ion generator to communicate with the fan assembly, the negative ion generator can continue to introduce negative ions into the sterilization space after the normal drying and sterilization work is completed, thereby further killing any bacteria that may be present in the sterilization space and further improving the sterilization effect of the kitchenware sterilizer.

[0033] Please refer to the following: Figures 1 to 6 This application provides a kitchenware sterilizer 100, which includes a main body 10 and an electric grid assembly 20. The main body 10 includes a shell 11 with a sterilization space (not labeled) and a fan assembly 12 disposed in the sterilization space. The shell 11 includes an air inlet 111, and the fan assembly 12 is used to drive outside air into the sterilization space through the air inlet 111. The electric grid assembly 20 is connected to the shell 11 and disposed at the air inlet 111. The electric grid assembly 20 includes a first mesh electrode 21 and a second mesh electrode 22 arranged sequentially at intervals along the direction of air flow through the air inlet 111, and an electric field is formed between the first mesh electrode 21 and the second mesh electrode 22.

[0034] The Kitchen Utensil Sterilizer 100 is a small household appliance specifically designed for the efficient sterilization, drying, and storage of kitchen utensils (such as knives, cutting boards, chopsticks, spoons, etc.). The Kitchen Utensil Sterilizer 100 can be countertop-mounted or wall-mounted, and its overall shape is a cuboid with one end open vertically upwards. One side of the open end features designated areas for chopsticks, cutlery, and cutting boards.

[0035] The main body 10 is a functional component of the kitchen sterilizer 100. The main body 10 includes a shell 11 with a sterilization space and a fan assembly 12 disposed in the sterilization space.

[0036] The outer casing 11 defines the shape of the kitchenware sterilizer 100. In these embodiments of the main body application, the shape of the outer casing 11 may be, but is not limited to, a cuboid, a cube, or a prism. The outer casing 11 has a sterilization space to support and store kitchenware, and to dry and sterilize the kitchenware stored in the sterilization space.

[0037] It is understood that the outer casing 11 typically includes a support frame 112, which may be integrally formed with the main structure of the outer casing 11, or the support frame 112 may be detachably connected to the main structure (unlabeled) of the outer casing 11. The support frame 112 may be used to provide support for chopsticks, spoons, forks, knives or cutting boards so that kitchen utensils can be stored in the sterilization space.

[0038] The outer casing 11 includes an air inlet 111, meaning that the main structure of the outer casing 11 includes an air inlet 111, so that the fan assembly 12 can draw outside air into the sterilization space.

[0039] The fan assembly 12 is the main component in the kitchenware sterilizer 100 that plays a sterilization role. The fan assembly 12 is used to drive outside air into the sterilization space through the air inlet 111. This means that the fan assembly 12 can generate a pressure difference between the sterilization space and the outside world near the air inlet 111, so that the outside air can be blown into the sterilization space through the air inlet 111 under the action of air pressure. The air generated by the fan assembly 12 dries the kitchenware stored in the sterilization space, destroys the environment in which bacteria can grow in the sterilization space, and thus achieves the effect of drying and sterilization.

[0040] The power grid assembly 20 is connected to the outer casing 11. In some implementations, the power grid assembly 20 can be fixedly connected to the outer casing 11 by welding, bonding, or even integral molding to improve the structural consistency between the power grid assembly 20 and the outer casing 11, thereby improving the structural stability of the power grid assembly 20 in the kitchen sterilizer 100 and reducing the risk of damage to the power grid assembly 20 during transportation. In some embodiments, the power grid assembly 20 and the outer casing 11 can also be detachably connected by means of snaps, slots, connectors (screws, bolts), etc., so that the power grid assembly 20 can be separated from the outer casing 11, which is beneficial for users to clean, repair or replace the power grid assembly 20.

[0041] The grid component 20 is located at the air inlet 111, which means that the grid component 20 is located close to the air inlet 111 to filter the gas entering the sterilization space through the air inlet 111, thereby reducing the probability of dust particles in the air entering the sterilization space.

[0042] Among them, fine dust can be, but is not limited to, PM2.5 particles, PM10 particles, black carbon particles (BC particles) or organic carbon particles (OC particles) in the air.

[0043] The power grid assembly 20 includes a first mesh electrode 21 and a second mesh electrode 22 arranged sequentially at intervals along the direction of air flow through the air inlet 111, and an electric field is formed between the first mesh electrode 21 and the second mesh electrode 22.

[0044] Both the first mesh electrode 21 and the second mesh electrode 22 are provided with perforated gaps 102, and multiple perforated gaps 102 together form a mesh structure of the electrodes. Simultaneously, the first mesh electrode 21 and the second mesh electrode 22 carry different types of charges, thereby forming an electric field between them and generating corona discharge. At this time, the mesh structure does not significantly affect airflow, and the corona discharge generated by the electric field can polarize and charge airborne dust particles, which are then attracted by the grid assembly 20.

[0045] The first mesh electrode 21 and the second mesh electrode 22 offer minimal obstruction to airflow, thus reducing the impact of the power grid assembly 20 on airflow. Simultaneously, the electric field between the first mesh electrode 21 and the second mesh electrode 22 can polarize and charge airborne dust particles, causing them to be adsorbed onto either the first mesh electrode 21 or the second mesh electrode 22 within the electric field.

[0046] At the same time, the first mesh electrode 21 and the second mesh electrode 22 can also hinder insects moving into the sterilization space through the air inlet 111, so that the insects dare not continue to move into the sterilization space after being electrocuted, which can further improve the cleanliness of the sterilization space.

[0047] Furthermore, in order to reduce the risk of users accidentally touching the power grid component 20 during operation, an anti-accidental contact net 113 can be installed at the air inlet 111. The anti-accidental contact net 113 has a mesh structure to reduce the risk of users accidentally touching the power grid component 20.

[0048] It is understood that in these embodiments of the present application, a high voltage can be provided between the first mesh electrode 21 and the second mesh electrode 22 so that corona discharge can be generated after the first mesh electrode 21 and the second mesh electrode 22 are energized, thereby polarizing and charging the micro-dust entering the electric field, and further adsorbing it onto the grid component 20.

[0049] In these embodiments of this application, the voltage of the power grid component 20 can be set to a high voltage between 10KV and 100KV. Exemplarily, but not limited to, the voltage of the power grid component 20 can be set to 20KV, 40KV, 60KV, 80KV, or 90KV.

[0050] In the technical solution of this application embodiment, an electric grid assembly 20 is provided at the air inlet 111 of the outer casing 11. The electric grid assembly 20 includes a first mesh electrode 21 and a second mesh electrode 22 arranged sequentially at intervals along the direction of air flow through the air inlet 111. An electric field is formed between the first mesh electrode 21 and the second mesh electrode 22. When the outside air is blown into the sterilization space through the air inlet 111 under the action of the fan assembly 12, it passes through the electric field formed by the first mesh electrode 21 and the second mesh electrode 22. This causes the dust particles in the air to be polarized in the electric field and adsorbed onto the electric grid assembly 20. At the same time, the electric grid assembly 20 can also prevent insects from entering the sterilization space through the air inlet 111 by electric shock, thereby improving the cleanliness of the sterilization space.

[0051] In some embodiments, the power grid assembly 20 further includes a voltage regulating device 23 connected to at least one of the first mesh electrode 21 and the second mesh electrode 22 to regulate the voltage between the first mesh electrode 21 and the second mesh electrode 22.

[0052] The voltage regulating device 23 is connected to at least one of the first mesh electrode 21 and the second mesh electrode 22 to regulate the voltage between the first mesh electrode 21 and the second mesh electrode 22. This means that the first mesh electrode 21 and the second mesh electrode 22 can be electrically connected through the voltage regulating device 23. At this time, the voltage regulating device 23 can be electrically connected to the first mesh electrode 21 and the second mesh electrode 22 respectively. Alternatively, the first mesh electrode 21 and the second mesh electrode 22 can also carry opposite charges and be spaced apart. In this case, the voltage regulating device 23 can be connected to either the first mesh electrode 21 or the second mesh electrode 22 to regulate the voltage of the power grid component 20 by adjusting the amount of charge on a single mesh electrode.

[0053] In some embodiments, both the first mesh electrode 21 and the second mesh electrode 22 are provided with a plurality of pore gaps 102, wherein the pore gap 102 of the one serving as the negative electrode is larger than the pore gap 102 of the one serving as the positive electrode.

[0054] Both the first mesh electrode 21 and the second mesh electrode 22 are provided with a plurality of perforated gaps 102, which can be formed by molding the first mesh electrode 21 and the second mesh electrode 22.

[0055] In these embodiments of this application, the first mesh electrode 21 is used as the positive electrode of the power grid component 20, and the second mesh electrode 22 is used as the negative electrode of the power grid component 20, as an example. The first mesh electrode 21 can be made of sheet metal stamping, thereby retaining a larger sheet metal area (smaller perforated gaps 102), so that when the dust particles are polarized by the electric field and become negatively charged, there is a larger sheet metal area for the dust particles to be adsorbed; the second mesh electrode 22 can be made of wire mesh, and the larger perforated gaps 102 form a corona region after passing a high voltage negative current, generating ionization, which can make the dust particles quickly become charged.

[0056] In some embodiments, the power grid assembly 20 further includes a mounting box 24 connected to the housing 11, and includes a first plate 241 and a second plate 242 disposed at opposite intervals, and a connecting hole 243 penetrating the first plate 241 and the second plate 242; a first mesh electrode 21 is disposed on the first plate 241 and covers the connecting hole 243, and a second mesh electrode 22 is disposed on the second plate 242 and covers the connecting hole 243.

[0057] The mounting box 24 is made of insulating material and is used to provide support for the first mesh electrode 21 and the second mesh electrode 22.

[0058] The mounting box 24 is connected to the outer casing 11. In a possible implementation, the mounting box 24 serves as the mounting structure for the first mesh electrode 21 and the second mesh electrode 22, and is fixedly connected to the outer casing 11 to improve the structural stability of the first mesh electrode 21 and the second mesh electrode 22 during the production process (the outer casing 11 and the mounting box 24 are produced separately, and then the two are fixed together). Alternatively, in some embodiments, the mounting box 24 may also be detachably connected to the outer casing 11 to facilitate the user to replace, repair, and clean the power grid component 20 during use.

[0059] The first plate 241 and the second plate 242 are mounting plates for the first mesh electrode 21 and the second mesh electrode 22, respectively. The connecting hole 243 is used to be arranged opposite to the air inlet 111 to improve the reliability of the connection between the external environment and the sterilization space.

[0060] The first mesh electrode 21 and the second mesh electrode 22 cover the connecting hole 243, meaning that in the relative arrangement direction of the first plate 241 and the second plate 242, the projection of the connecting hole 243 falls within the projection of the first mesh electrode 21 and the second mesh electrode 22.

[0061] In some embodiments, the mounting box 24 further includes a plurality of third plates 244 connecting the first plate 241 and the second plate 242. The first plate 241, the second plate 242 and the plurality of third plates 244 together form an accommodating space (not labeled), and the first mesh electrode 21 and the second mesh electrode 22 are both disposed within the accommodating space.

[0062] The third plate 244 connects the first plate 241 and the second plate 242, meaning that the third plate 244 is a side wall structure of the mounting box 24. The number of third plates 244 depends on the structure of the mounting box 24. For example, in a rectangular structure of the mounting box 24, there are four third plates 244; in a triangular prism structure of the mounting box 24, there are four third plates 244.

[0063] The first plate 241, the second plate 242, and multiple third plates 244 together form a receiving space. The first mesh electrode 21 and the second mesh electrode 22 are both set in the receiving space, so as to provide a good and stable working environment for the first mesh electrode 21 and the second mesh electrode 22 by utilizing the receiving space, reducing the risk of the external environment affecting the operation of the first mesh electrode 21 and the second mesh electrode 22, and effectively improving the reliability of the kitchenware sterilizer 100.

[0064] In some embodiments of this application, the mounting box 24 may also be provided with an insulating support ring 245, wherein the insulating support ring 245 is disposed in the accommodating space and connected to at least part of the third plate 244. In this case, the insulating support ring 245 can cooperate with the first plate 241 and the second plate 242 respectively to form mounting spaces within the accommodating space, so as to further improve the mounting reliability of the first mesh electrode 21 and the second mesh electrode 22.

[0065] In some embodiments, the insulating support ring 245 can be configured as a ring structure. That is, when the mounting box 24 is a rectangular body, the insulating support ring 245 can be configured as a rectangular ring; when the mounting box 24 is a triangular prism, the insulating support ring 245 can be configured as a triangular ring.

[0066] In some embodiments, at least one of the plurality of third plates 244 is provided with a power port 2441, which connects the accommodating space and the sterilization space.

[0067] The placement of the power port 2441 further optimizes the structure of the grid assembly 20, allowing the containment space to be dedicated to the adsorption of micro-dust. This allows other components connected to the first mesh electrode 21 and the second mesh electrode 22 (such as the voltage regulator 23, the controller 50 of the kitchen sterilizer 100, and the power supply) to be placed in the sterilization space without occupying the containment space, thus further improving the reliability of the kitchen sterilizer 100.

[0068] At this time, the first mesh electrode 21 and the second mesh electrode 22 can be electrically connected to other components in the sterilization space through the power port 2441. The opening structure of the power port 2441 is simple and easy to implement, which is conducive to improving the production efficiency of the kitchen sterilizer 100.

[0069] In some embodiments, the main body 10 further includes a baffle plate 13, which is disposed in the sterilization space and divides the sterilization space into a first subspace 1011 and a second subspace 1012. The baffle plate 13 is provided with an air outlet 131, which connects the first subspace 1011 and the second subspace 1012. The first subspace 1011 is used to store kitchen utensils. The fan assembly 12 and the grid assembly 20 are disposed in the second subspace 1012, and the outer shell 11 is provided with an air inlet 111 corresponding to the portion of the second subspace 1012.

[0070] The water-retaining tray 13 is set in the sterilization space and divides the sterilization space into a first subspace 1011 and a second subspace 1012. The first subspace 1011 is used to store kitchen utensils, and the fan assembly 12 and the grid assembly 20 are set in the second subspace 1012. That is, the first subspace 1011 is the space actually used to store kitchen utensils, and the second subspace 1012 is the space used to set up electronic devices such as the fan assembly 12, the grid assembly 20, the voltage regulator 23, and the controller 50. At this time, the water-retaining tray 13 can isolate the water vapor that may exist in the first subspace 1011 from the second subspace 1012, reducing the risk of electronic devices being corroded by water vapor.

[0071] The baffle plate 13 is provided with an air outlet 131, which connects the first subspace 1011 and the second subspace 1012. That is, when the kitchen sterilizer 100 is working, the outside air enters the second subspace 1012 through the air inlet 111 under the action of the fan assembly 12, and then is blown from the second subspace 1012 into the first subspace 1011 through the air outlet 131.

[0072] In some embodiments, the fan assembly 12 includes a fan body 121 and a heating device 122, a power grid assembly 20 is disposed between the fan body 121 and the air inlet 111, and the heating device 122 is disposed at the output end of the fan body 121.

[0073] The fan body 121 is a component in the fan assembly 12 specifically used to generate negative pressure. In these embodiments of the present application, the fan body 121 can be configured as a blower.

[0074] The heating device 122 is used to heat the air blown out by the fan body 121 at the output end of the fan body 121, thereby increasing the temperature of the gas blown into the first subspace 1011 by the fan assembly 12, and thereby increasing the rate of water vapor evaporation and dissipation in the first subspace 1011 by using the higher temperature, which can further improve the drying and sterilization effect on the sterilization space.

[0075] In these embodiments of the present application, the heating device 122 may be configured as a ceramic heating element or a PTC (Positive Temperature Coefficient) heating module, but is not limited to.

[0076] In some embodiments, the kitchen sterilizer 100 further includes a dust concentration sensor 30, which is communicatively connected to the power grid assembly 20 and is disposed on the side of the housing 11 away from the sterilization space.

[0077] The dust concentration sensor 30 is used to monitor the concentration of dust particles in the air surrounding the kitchen sterilizer 100, and then adjusts the voltage of the grid component 20 according to the concentration of dust particles in the air. That is, when the dust concentration sensor 30 senses a high concentration of dust particles in the air surrounding the kitchen sterilizer 100, it can further enhance the adsorption effect of the grid component 20 on dust particles by increasing the voltage of the grid component 20, thereby improving the sterilization effect; when the dust concentration sensor 30 senses a low concentration of dust particles in the air surrounding the kitchen sterilizer 100, it can reduce the energy consumption of the kitchen sterilizer 100 while meeting the sterilization requirements, thereby improving economic and environmental benefits.

[0078] In these embodiments of the present application, the dust concentration sensing device 30 is communicatively connected to the power grid component 20. Possible implementations include wired communication between the dust concentration sensing device 30 and the power grid component 20 via signal lines or wires; alternatively, wireless communication between the dust concentration sensing device 30 and the power grid component 20 can be achieved via WIFI, Bluetooth, or other protocols, enabling the dust concentration sensing device 30 to transmit the sensed dust concentration data to the power grid component 20 for voltage regulation.

[0079] It is understood that in some embodiments, the dust concentration sensing device 30 and the power grid component 20 may be connected in communication via the controller 50. That is, the dust concentration sensing device 30 and the power grid component 20 are indirectly connected in communication via the controller 50. After receiving the dust concentration signal from the dust concentration sensing device 30, the controller 50 controls the voltage regulating device 23 to adjust the voltage of the power grid component 20.

[0080] In some embodiments, the kitchen sterilizer 100 further includes a negative ion generator 40, which is communicatively connected to the fan assembly 12 and is used to release negative ions into the sterilization space.

[0081] The negative ion generator 40 is used to generate negative ions to kill bacteria in the air.

[0082] The negative ion generator 40 is communicatively connected to the fan assembly 12. Possible implementations include wired communication via signal lines or wires; or wireless communication via WIFI, Bluetooth, or other protocols, enabling the negative ion generator 40 and the fan assembly 12 to work together and achieve sterilization of the sterilized space.

[0083] For example, in some embodiments, after the fan assembly 12 completes the drying and sterilization work, the controller 50 can control the heating device 122 to stop working in order to reduce the energy consumption of the kitchenware sterilizer 100, and at the same time drive the fan body 121 and the negative oxygen ion generator 40 to work, so as to blow the negative oxygen ions generated by the negative oxygen ion generator 40 into the first subspace 1011 to kill the bacteria in the first subspace 1011.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
