Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a disinfection device. Background Technology

[0002] With increasing health awareness, disinfection devices with functions such as drying, sterilization, heat preservation, and dehumidification are becoming increasingly popular and are gradually becoming common household appliances. In related technologies, the disinfection device includes a main body, a fan, and a heating element. The main body has a chamber, a first air inlet, and a first air outlet communicating with the chamber. The fan draws outside air into the chamber through the first air inlet, where it is heated by the heating element, and then discharged through the first air outlet.

[0003] However, the external gas inside the chamber of the disinfection device in the relevant technology is uneven, resulting in low disinfection and drying efficiency. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a disinfection device with high gas flow rate, uniform external gas distribution, and high disinfection and drying efficiency.

[0005] The disinfection device of this utility model embodiment includes:

[0006] The body has a chamber, a first air inlet and a first air outlet, both of which are connected to the chamber and are located on the first side wall of the body.

[0007] An air supply assembly is disposed within the main body. The air supply assembly includes a first fan, which is used to draw outside air into the cavity through the first air inlet.

[0008] A second fan is disposed within the body and adjacent to the first air outlet. The second fan is positioned higher than the first fan and is used to discharge the gas in the cavity through the first air outlet.

[0009] In this embodiment of the disinfection device, a first fan draws outside air into the chamber through a first air inlet for disinfection and drying of items inside the chamber. At the same time, a second fan discharges the existing air inside the chamber through a first air outlet, allowing outside air to enter the chamber as quickly as possible and accelerating the flow rate of outside air within the chamber. This enables the outside air inside the chamber to achieve rapid equilibrium and improves the disinfection and drying efficiency.

[0010] Optionally, the main body further includes a mounting plate and a back plate. The mounting plate is the rear side wall of the chamber, and the back plate covers the mounting plate. The first side wall is the back plate, and the first air inlet is located at the lower end of the back plate, and the first air outlet is located at the upper end of the back plate.

[0011] The disinfection device of this utility model introduces external gas into the chamber through the first air inlet. The external gas flows upward from the bottom of the chamber and is discharged from the top of the back plate through the first air outlet. This accelerates the flow of external gas in the chamber and improves the disinfection and drying efficiency of the chamber.

[0012] Optionally, the mounting plate and the back plate form a receiving cavity, the first air inlet and the first air outlet are disposed on the back plate and communicate with the receiving cavity, the air supply assembly and the second fan are located in the receiving cavity, the mounting plate is provided with a second air inlet communicating with the outlet of the first fan and a second air outlet adjacent to the second fan, and both the second air inlet and the second air outlet communicate with the receiving cavity and the chamber.

[0013] The disinfection device of this utility model uses a mounting plate and a back plate to form a receiving cavity, which makes reasonable use of space, facilitates the installation of the air supply component and the second fan, and the distribution of the second air inlet and the second air outlet. The first fan introduces the outside gas in the receiving cavity into the cavity through the second air inlet, and the second fan draws out the original gas in the cavity through the second air outlet, so that the outside gas can quickly fill the cavity and form a circulating airflow, thereby improving the disinfection and drying efficiency in the cavity.

[0014] Optionally, the second air inlet is located at the lower end of the mounting plate, and the second air outlet is located at the upper end of the mounting plate; and / or,

[0015] The air supply assembly also includes a housing, which has an air supply channel inside. One end of the air supply channel is connected to the outlet of the first fan, and the other end of the air supply channel is connected to the second air inlet.

[0016] In this embodiment of the disinfection device, the second air inlet is located at the lower end of the mounting plate, and the second air outlet is located at the upper end of the mounting plate. The first fan introduces external gas into the chamber through the second air inlet. The external gas flows upward from the bottom of the chamber. The second fan discharges the original gas in the chamber from the top through the second air outlet, which accelerates the flow of external gas in the chamber and improves the disinfection and drying efficiency of the chamber. By setting up an air supply channel, the external gas drawn into the receiving chamber by the first fan is regulated, reducing the airflow from escaping to the surroundings in the receiving chamber and increasing the flow rate of external gas flowing into the chamber through the second air inlet.

[0017] Optionally, the air supply channel has at least one baffle to divide at least a portion of the air supply channel into multiple spaced sub-channels, the housing is provided with multiple air supply outlets, each sub-channel corresponding to one air supply outlet, and there are multiple second air inlets, each of the multiple second air inlets corresponding to and communicating with the multiple air supply outlets; and / or,

[0018] The disinfection device also includes a heating component, which is located in the air supply channel and is used to heat the gas in the air supply channel.

[0019] The disinfection device of this utility model divides the air supply channel into multiple sub-channels by a baffle, so that the outside gas in the air supply channel can enter the chamber through multiple air supply outlets, increasing the total area of ​​the air supply outlets and allowing the outside gas in the air supply channel to enter the chamber more quickly. Moreover, the multiple sub-channels are arranged at intervals and correspond one-to-one with multiple air supply outlets, making the air supply to the chamber through the air supply channel more uniform and improving work efficiency. The heating component heats the outside gas in the air supply channel, which facilitates the diffusion of the outside gas in the chamber, so that the outside gas in the chamber can be heated quickly and evenly, improving the disinfection and drying efficiency.

[0020] Optionally, the air supply channel includes a first section and a second section. One end of the first section is connected to the outlet of the first fan, and the other end of the first section is connected to one end of the second section. The other end of the second section is connected to the second air inlet. The cross-sectional area of ​​the second section is larger than that of the first section. The baffle is disposed in the second section to divide the second section into multiple sub-channels.

[0021] In this embodiment of the disinfection device, the cross-sectional area of ​​the second section is larger than that of the first section, which increases the flow rate of air from the first section to the second section, thereby increasing the speed at which external gas enters the chamber. Moreover, the structure of the air supply channel is simple, saving manufacturing costs.

[0022] Optionally, at least a portion of the cross-sectional area of ​​the second segment gradually increases in a direction away from the first segment.

[0023] The disinfection device of this utility model embodiment, through the above-mentioned configuration, increases the flow rate of external gas as it flows from the first section to the second section, thereby improving the efficiency of external gas entering the chamber and thus improving the disinfection and drying efficiency of the chamber.

[0024] Optionally, the second segment includes a gradually widening portion and a straight portion, one end of the gradually widening portion is connected to the other end of the first segment, the other end of the gradually widening portion is connected to one end of the straight portion, the cross-sectional area of ​​the gradually widening portion gradually increases in the direction away from the first segment, and the cross-sectional area of ​​the straight portion is constant in the direction away from the first segment.

[0025] In this embodiment of the disinfection device, the cross-sectional area of ​​the expanding section gradually increases in the direction away from the first section, thereby increasing the flow rate of external gas from the first section to the second section. The cross-sectional area of ​​the straight section remains constant in the direction away from the first section, so that external gas can be stored in the straight section, ensuring that external gas can continuously enter the chamber through the second section, thus ensuring disinfection and drying efficiency.

[0026] Optionally, there are at least two baffles, which are arranged at intervals along the first direction. The baffles are curved plates that extend from one end of the second segment away from the first segment and are curved toward the outside of the housing.

[0027] The disinfection device of this utility model reduces the collision between the external gas and the baffle when the external gas flows by setting the baffle as a curved plate, thus ensuring the flow rate of the external gas.

[0028] Optionally, the housing includes a first housing portion and a second housing portion, which are detachably connected. The first housing portion has a first air supply groove, and the second housing portion has a second air supply groove.

[0037] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] like Figure 1-6 As shown, the disinfection device of this utility model embodiment includes a main body 1, an air supply assembly 2, and a second fan 3. The main body 1 has a chamber 11, a first air inlet 12, and a first air outlet 13. Both the first air inlet 12 and the first air outlet 13 are connected to the chamber 11 and are located on the first side wall of the main body 1. The air supply assembly 2 is located inside the main body 1 and includes a first fan 21, which draws outside air into the chamber 11 through the first air inlet 12. The second fan 3 is located inside the main body 1 and adjacent to the first air outlet 13. The second fan 3 is positioned higher than the first fan 21 and discharges the air from the chamber 11 through the first air outlet 13.

[0039] In this embodiment of the disinfection device, the first fan 21 draws outside air into the chamber 11 through the first air inlet 12 for disinfection and drying of the items in the chamber 11. At the same time, the second fan 3 discharges the original air in the chamber 11 through the first air outlet 13, so that outside air can enter the chamber 11 as quickly as possible, thereby accelerating the flow rate of outside air in the chamber 11 and enabling the outside air in the chamber 11 to achieve rapid and balanced distribution, thus improving the disinfection and drying efficiency.

[0040] Specifically, such as Figure 4 As shown, the first air inlet 12 is provided with a plurality of evenly distributed first air inlet holes 14, through which outside air enters the chamber 11. The arrangement of the plurality of first air inlet holes 14 can also filter the outside air, reducing the amount of waste larger than the first air inlet holes 14 from entering the chamber 11.

[0041] Furthermore, such as Figure 1 As shown, a first grille 151 is provided at the first air inlet 12 to further filter the outside air and ensure that the air entering the chamber 11 is clean.

[0042] Specifically, such as Figure 1 As shown, there are multiple first air outlets 13, which are evenly and densely distributed to improve the efficiency of gas discharge from the chamber 11.

[0043] In some embodiments, such as Figure 1 As shown, the main body 1 includes a mounting plate 16 and a back plate 18. The mounting plate 16 is the rear side wall of the chamber 11, and the back plate 18 is covered on the mounting plate 16. The first side wall is the back plate 18, and the first air inlet 12 is located at the lower end of the back plate 18, and the first air outlet 13 is located at the upper end of the back plate 18.

[0044] Specifically, the mounting plate 16 and the back plate 18 form a receiving cavity 111. The first air inlet 12 and the first air outlet 13 are located on the back plate 18 and communicate with the receiving cavity 111. The air supply component 2 and the second fan 3 are located in the receiving cavity 111, which realizes the rational use of space, facilitates the installation of the air supply component 2 and the second fan 3, and the distribution of the second air inlet 161 and the second air outlet 162.

[0045] Mounting plate 16 is provided with a second air inlet 161 and a second air outlet 162. The second air inlet 161 is connected to the outlet of the first fan 21, and the second air outlet 162 is adjacent to the second fan 3. Both the second air inlet 161 and the second air outlet 162 are connected to the receiving cavity 111 and the chamber 11.

[0046] Specifically, the first fan 21 introduces the outside gas in the receiving cavity 111 into the cavity 11 through the second air inlet 161, and the second fan 3 draws out the original gas in the cavity 11 through the second air outlet 162, so that the outside gas can quickly fill the cavity 11 and form a circulating airflow, thereby improving the disinfection and drying efficiency in the cavity 11.

[0047] Specifically, such as Figure 6 As shown, a second grille 152 is provided at the second air inlet 161 to filter the outside air flowing into the chamber 11, reduce the amount of garbage entering the chamber 11, and ensure that the chamber 11 is clean. There are multiple second air outlets 162, which are evenly and densely distributed to improve the efficiency of the original air discharge in the chamber 11.

[0048] In some embodiments, such as Figure 1As shown, the second air inlet 161 is located at the lower end of the mounting plate 16, and the second air outlet 162 is located at the upper end of the mounting plate 16. Specifically, the first fan 21 introduces external gas into the chamber 11 through the second air inlet 161. The external gas flows upward from the bottom of the chamber 11. The second fan 3 discharges the original gas in the chamber 11 from the top through the second air outlet 162, which accelerates the flow of internal and external gas in the chamber 11 and improves the efficiency of disinfection and drying in the chamber 11.

[0049] like Figure 2 and Figure 3 As shown, the air supply assembly 2 also includes a housing 22, and an air supply channel 23 is provided inside the housing 22. One end of the air supply channel 23 (e.g. Figure 1 The upper end of the air supply duct 23 shown is connected to the outlet of the first fan 21, and the other end of the air supply duct 23 (as shown) is connected to the outlet of the first fan 21. Figure 1 The lower end of the air supply channel 23 shown is connected to the second air inlet 161. Specifically, by setting the air supply channel 23, the external gas drawn into the receiving cavity 111 by the first fan 21 is regulated, reducing the airflow from the receiving cavity 111 to the surroundings, and increasing the flow rate of the external gas into the cavity 11 through the second air inlet 161.

[0050] In some embodiments, such as Figure 3 As shown, the air supply channel 23 has at least one baffle 24 to divide at least a portion of the air supply channel 23 into a plurality of spaced sub-channels 231. The housing 22 is provided with a plurality of air supply outlets 221, and each sub-channel 231 corresponds to one air supply outlet 221. There are a plurality of second air inlets 161, and the plurality of second air inlets 161 correspond one-to-one with the plurality of air supply outlets 221 and are connected.

[0051] Specifically, the air supply channel 23 is divided into multiple sub-channels 231 by the baffle 24, so that the outside air in the air supply channel 23 can enter the chamber 11 through multiple air supply outlets 221, which increases the total area of ​​the air supply outlets 221, allowing the outside air in the air supply channel 23 to enter the chamber 11 more quickly. Moreover, the multiple sub-channels 231 are arranged at intervals and correspond one-to-one with the multiple air supply outlets 221, making the air supply to the chamber 11 through the air supply channel 23 more uniform and improving work efficiency.

[0052] In some embodiments, such as Figure 1 As shown, the disinfection device also includes a heating component 4, which is located in the air supply channel 23 and is used to heat the gas in the air supply channel 23. This facilitates the diffusion of external gas in the chamber 11, allowing the external gas in the chamber 11 to heat up quickly and evenly, thereby improving the disinfection and drying efficiency.

[0053] Specifically, the heating component 4 can be an air heater.

[0054] Specifically, when the disinfection device is started, the first fan 21 and the second fan 3 are turned on simultaneously. The first fan 21 draws outside air into the air supply channel 23, where it is heated by the heating component 4 before entering the chamber 11. Simultaneously, the second fan 3 draws out the existing air in the chamber 11 through the first air outlet 13, allowing the heated outside air to enter the chamber 11 as quickly as possible. The second fan 3 stops operating after a preset time, specifically 3 minutes, while the first fan 21 continues to operate to disinfect and dry the items in the chamber 11.

[0055] After the disinfection process is completed, the disinfection device begins its cooling process. The heating component 4 is turned off, and the first fan 21 and the second fan 3 are turned on simultaneously. The first fan 21 draws outside air into the air supply channel 23 through the first air inlet 12, and then into the chamber 11 through the air supply channel 23. At the same time, the second fan 3 draws out the original hot air in the chamber 11 through the first air outlet 13, so that the cooler outside air in the air supply channel 23 can quickly enter the chamber 11 to rapidly cool and dry the items in the chamber 11, preventing users from being burned and making it convenient for users to use the disinfected and dried items in the chamber 11, thus improving the user experience.

[0056] In some other embodiments, the heating component 4 may not be installed in the air supply channel 23, and the items in the chamber 11 may be disinfected and dried directly by the outside gas. Specifically, the outside gas may be ozone.

[0057] In some embodiments, such as Figure 2 As shown, the air supply duct 23 includes a first section 232 and a second section 233. One end of the first section 232 (as shown) Figure 1 The upper end of the first segment 232 (as shown) is connected to the outlet of the first fan 21, and the other end of the first segment 232 (as shown) Figure 1 The lower end of the first segment 232 shown) and one end of the second segment 233 (as shown) Figure 1 The upper end of the second segment 233 shown is connected, and the other end of the second segment 233 (as shown) is connected. Figure 1 The lower end of the second segment 233 (shown) is connected to the second air inlet 161. The cross-sectional area of ​​the second segment 233 is larger than that of the first segment 232, which increases the airflow velocity from the first segment 232 to the second segment 233, thereby increasing the velocity of external gas entering the chamber 11. A baffle 24 is provided inside the second segment 233 to divide the second segment 233 into multiple sub-channels 231, thus simplifying the structure of the sub-channels 231. In addition, the air supply channel 23 has a simple structure, saving manufacturing costs.

[0058] In some embodiments, such as Figure 2 and Figure 3As shown, at least a portion of the cross-sectional area of ​​the second segment 233 gradually increases in the direction away from the first segment 232, so that when the external gas in the first segment 232 flows to the second segment 233, the flow velocity gradually increases, thereby improving the efficiency of the external gas entering the chamber 11 and thus improving the disinfection and drying efficiency of the chamber 11.

[0059] In some embodiments, such as Figure 2 As shown, the second segment 233 includes a widening portion 2331 and a straight portion 2332. One end of the widening portion 2331 (as shown) Figure 1 The upper end of the gradually expanding portion 2331 shown is connected to the other end of the first segment 232, and the other end of the gradually expanding portion 2331 (as shown) Figure 1 The lower end of the gradually widening portion 2331 shown) and one end of the straight portion 2332 (as shown) Figure 1 The upper end of the straight section 2332 shown is connected, the cross-sectional area of ​​the gradually expanding section 2331 gradually increases in the direction away from the first section 232, and the cross-sectional area of ​​the straight section 2332 is constant in the direction away from the first section 232.

[0060] Specifically, the cross-sectional area of ​​the expanding section 2331 gradually increases in the direction away from the first section 232, which increases the flow rate of external gas from the first section 232 to the second section 233. The cross-sectional area of ​​the straight section 2332 is constant in the direction away from the first section 232, so that external gas can be stored in the straight section 2332, ensuring that external gas can continuously enter the chamber 11 through the second section 233, thus ensuring the efficiency of disinfection and drying.

[0061] Specifically, such as Figure 2 As shown, the connection between the lower end of the expanding section 2331 and the upper end of the straight section 2332 is arc-shaped, and the connection between the upper end of the expanding section 2331 and the lower end of the first section 232 is also arc-shaped, so as to reduce the collision between the wall surface of the second section 233 and the external gas, so that the external gas can flow smoothly in the second section 233 and ensure the flow rate of the external gas.

[0062] In some embodiments, there are at least two baffles 24, which are spaced apart along a first direction orthogonal to the vertical direction. The baffles 24 are curved plates, extending from one end of the second segment 233 in a direction away from the first segment 232 and curving outwards from the housing 22. Specifically, by making the baffles 24 curved plates, the collision between the external gas and the baffles 24 during gas flow is reduced, ensuring the flow rate of the external gas.

[0063] Specifically, such as Figure 2 As shown in Figure 3, the baffle 24 is provided with a groove 241 to reduce the weight of the baffle 24 itself, thereby reducing the overall weight of the air supply assembly 2 and saving materials and costs.

[0064] In some embodiments, such as Figure 1 As shown, the housing 22 includes a first housing portion 222 and a second housing portion 223, which are detachably connected to facilitate cleaning and maintenance of the internal components of the housing 22. The first housing portion 222 has a first air supply groove (not shown), and the second housing portion 223 has a second air supply groove 2231. The first air supply groove and the second air supply groove 2231 form an air supply channel 23, which increases the volume of the air supply channel 23, allowing it to hold more external gas, increasing the air output of the air supply channel 23, and improving the efficiency of air diffusion into the chamber 11.

[0065] In some embodiments, such as Figure 1 As shown, the main body 1 also includes a base portion 17. A mounting plate 16 is provided at one end of the base portion 17 and forms a cavity 11 with the base portion 17. A back plate 18 is detachably connected to one end of the base portion 17.

[0066] Specifically, the back plate 18 and the base 17 are detachably connected, which facilitates the cleaning, replacement and maintenance of the components in the receiving cavity 111 after long-term use of the disinfection device. Moreover, the structure of the main body 1 is simple, saving manufacturing costs.
