Description

Technical Field

[0001] The present invention relates to the technical field of disinfection cabinets, and in particular to a disinfection cabinet and a method for using the same. Background Art

[0002] Existing disinfection cabinets typically have both drying and disinfection functions. Since the items to be disinfected will retain some moisture after washing, they must be dried before being placed in the disinfection cabinet for formal disinfection. The drying temperature is typically around 120 degrees Celsius. After drying, the items are then disinfected using disinfection methods such as ultraviolet light or ozone.

[0003] The existing disinfection cabinet is equipped with a hot air device and a hot air outlet. When drying items, the hot air device inside the disinfection cabinet generates hot air of about 120 degrees Celsius. The hot air is blown into the disinfection space in the disinfection cabinet through the hot air outlet, and the objects are dried by the hot air.

[0004] However, when existing disinfection cabinets are used to dry some bottle containers, a lot of moisture will adhere to the inner surface of the bottle containers after cleaning. During drying, since the inner space of the bottle containers is relatively closed and the air flow inside the bottle containers is poor, the hot air in the disinfection cabinet is difficult to blow directly into the interior of the bottle containers, resulting in a slow drying speed of the inner surface of the bottle containers. When setting the drying time of the disinfection cabinet, the drying time often needs to be set longer, resulting in an increase in the time spent on the entire drying and disinfection process and an increase in electricity consumption. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies in the prior art and to provide a disinfection cabinet and a method for using the same.

[0007] Preferably, the air outlet control mechanism includes a first limiting ring, a second limiting ring, a slip ring, and a push rod. The first limiting ring and the second limiting ring are fixedly arranged in the air outlet duct, and the air outlet is located between the first limiting ring and the second limiting ring. The slip ring is slidably arranged in the air outlet duct, and the slip ring is located between the first limiting ring and the second limiting ring. A spring is provided between the lower end of the slip ring and the second limiting ring. The lower end of the push rod is connected to the slip ring, and the upper end of the push rod is higher than the upper end of the air outlet duct. When the bottle container is placed upside down on the air outlet duct, the push rod contacts the bottle container, and the slip ring is located below the air outlet to keep the air outlet in an open state. When the air outlet duct is in an unloaded state, the slip ring contacts the first limiting ring, and the slip ring blocks the air outlet to keep the air outlet in a closed state.

[0008] Preferably, the bottle container placement rack includes two air inlet pipes, and the transition pipes on the two air inlet pipes are connected by a connecting sleeve; the two air inlet pipes are respectively provided with a shelf plate; the bottle container placement rack is placed on the positioning bar through the shelf plate.

[0009] Preferably, a positioning hole is provided on the positioning bar, and a positioning boss that matches the positioning hole is provided at the lower end of the shelf plate.

[0010] Preferably, a butt joint pipe is provided in the air inlet of the air inlet pipe, and a flexible contact cover is provided at one end of the butt joint pipe.

[0011] Preferably, the docking tube and the air inlet pipe are slidably fitted together, and a contact pressure piece is provided between the air inlet pipe and the docking tube; the contact pressure piece is arc-shaped, and includes a first material layer and a second material layer, the first material layer is located on the inner side of the arc of the second material layer, and the thermal expansion coefficient of the first material layer is greater than the thermal expansion coefficient of the second material layer; when the temperature of the contact pressure piece rises, the distance between the two ends of the contact pressure piece increases.

[0012] Preferably, a first connection portion is provided on the inner wall of the air inlet pipe, a second connection portion is provided on the inner wall of the docking pipe, one end of the contact pressure member is connected to the first connection portion, and the other end of the contact pressure member is connected to the second connection portion.

[0013] Preferably, the air outlets are evenly arranged along the circumference of the air outlet pipe.

[0014] Preferably, the cross section of the positioning strip is L-shaped.

[0015] A method for using a disinfection cabinet comprises the following specific steps: The bottle container rack is taken out of the disinfection cabinet body, and the bottle container to be disinfected is placed upside down on the air outlet pipe of the bottle container rack. After the bottle container is placed, the bottle container rack containing the bottle container is installed into the disinfection space in the disinfection cabinet body. The shelf plates on both sides of the bottle container rack are placed on the positioning strips, and the positioning bosses at the lower ends of the shelf plates are snapped into the positioning holes on the positioning strips. When the bottle container rack is in place, the air inlet on the air inlet pipe is coupled with the hot air outlet. After the disinfection cabinet starts the drying program, hot air is blown out from the hot air outlet. The hot air blown out from the hot air outlet corresponding to the air inlet passes through the air inlet pipe, transition pipe, air outlet pipe in sequence and is finally blown out from the air outlet. The hot air blown out from the air outlet dries the inside of the bottle container.

[0016] The beneficial effects of the present invention are: The hot air blown out from the hot air outlet coupled with the air inlet will enter the air inlet pipe, and then pass through the transition pipe, the air outlet pipe and finally be blown out from the air outlet, and the hot air blown out from the air outlet will be blown into the bottle container, thereby drying the interior of the bottle container with hot air. When drying the bottle container, the hot air can be effectively introduced into the interior of the bottle container, greatly accelerating the air flow and drying speed inside the bottle container, thereby shortening the time of the whole process of drying and disinfecting, and saving the consumption of electric energy.

[0017] 2. The air outlet pipe is provided with an air outlet control mechanism, which can automatically adjust the air outlet state of the air outlet: when the bottle container is turned upside down on the air outlet pipe, the air outlet is opened, and the hot air acts precisely on the bottle container; when the air outlet pipe is unloaded, the air outlet is closed to prevent the hot air from spreading aimlessly to the disinfection space; in this way, all the hot air entering the air inlet pipe can be distributed to the internal space of the bottle container that needs to be dried, thereby improving the utilization rate of the hot air and achieving the design purpose of on-demand air outlet.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention are within the scope of protection of the present invention.

[0030] It should be understood by those skilled in the art that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0031] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0032] like Figures 1 to 10 As shown, a disinfection cabinet comprises a disinfection cabinet body 1 and a bottle container placement rack 3. A disinfection space is provided in the disinfection cabinet body 1, and a positioning strip 2 is fixedly provided in the disinfection space. The bottle container placement rack 3 is placed in the disinfection space and rests on the positioning strip 2; a hot air outlet 1-1 is provided on one side of the disinfection space, and the hot air outlets 1-1 are arranged in a straight line; the bottle container placement rack 3 comprises an air inlet pipe 3-1, a plurality of transition pipes 3-2 are provided on the air inlet pipe 3-1, a plurality of air outlet pipes 3-3 are provided on the transition pipe 3-2, and an air outlet 3-11 is provided on the air outlet pipe 3-3; an air outlet control mechanism for controlling the opening and closing of the air outlet 3-11 is provided on the air outlet pipe 3-3; when the bottle container 5 is upside down on the air outlet pipe 3-3, the air outlet 3-11 is in an open state; when the air outlet pipe 3-3 is in an unloaded state, the air outlet 3-11 is in a closed state.

[0033] One end of the air inlet pipe 3-1 is an air inlet; when the bottle container placement rack 3 is placed in the disinfection space, the air inlet on the air inlet pipe 3-1 is coupled with the hot air outlet 1-1 so that the hot air blown out from the hot air outlet 1-1 enters the air inlet pipe 3-1.

[0034] The air inlet duct 3-1, transition duct 3-2, and air outlet duct 3-3 are interconnected, allowing air to flow through the three ducts in sequence. When the bottle container rack 3 is placed in the disinfection space, the air inlet duct 3-1 and transition duct 3-2 are horizontal, and the air outlet duct 3-3 is vertical.

[0035] When drying the bottle container 5, the bottle container 5 is placed upside down on the air outlet pipe 3-3, and the air outlet 3-11 on the air outlet pipe 3-3 extends into the inner space of the bottle container 5; during the drying process, the hot air blown out by the hot air outlet 1-1 not coupled with the air inlet will be directly blown into the disinfection space in the disinfection cabinet body 1, and this part of the hot air will be blown toward the outer surface of the bottle container 5, directly drying the outer surface of the bottle container 5; while the hot air blown out by the hot air outlet 1-1 coupled with the air inlet will be blown into the disinfection space in the disinfection cabinet body 1. The hot air enters the air inlet duct 3-1, then passes through the transition duct 3-2, the air outlet duct 3-3, and finally is blown out of the air outlet 3-11. The hot air blown out of the air outlet 3-11 is blown into the bottle container 5, thereby drying the interior of the bottle container 5 with hot air. When drying the bottle container 5, the present invention can effectively introduce hot air into the interior of the bottle container 5, greatly accelerating the air flow and drying speed inside the bottle container 5, thereby shortening the entire drying and disinfection process and saving energy. In traditional disinfection cabinet technology, when drying the bottle container 5, the hot air is difficult to introduce into the inner wall of the bottle container 5, resulting in a longer drying time and high energy consumption.

[0036] An air outlet control mechanism is provided on the air outlet pipe 3-3; the air outlet control mechanism on the air outlet pipe 3-3 can automatically adjust the air outlet state of the air outlet 3-11: when the bottle container 5 is turned upside down on the air outlet pipe 3-3, the air outlet 3-11 is opened, and the hot air acts precisely on the bottle container 5; when the air outlet pipe 3-3 is unloaded, the air outlet 3-11 is closed to prevent the hot air from spreading aimlessly to the disinfection space; in this way, all the hot air entering the air inlet pipe 3-1 can be distributed to the internal space of the bottle container that needs to be dried, thereby improving the utilization rate of the hot air and achieving the design purpose of on-demand air outlet.

[0037] The bottle container rack 3 of the present invention adopts a completely detachable design. When sterilizing the bottle containers 5, the bottle container rack 3 can be taken out of the sterilizer first, and the bottle containers 5 to be sterilized can be placed one by one on the bottle container rack 3. After the bottle containers are full, the bottle container rack 3 is placed back into the sterilizer. This detachable design allows the user to take the rack out of the sterilizer and load the bottle containers 5 individually, avoiding the need to place them one by one in the narrow sterilization space. It is particularly suitable for loading a large number of or tall bottles (such as baby bottles and thermos cups), reducing the difficulty of operation. Moreover, when the interior of the sterilizer needs to be cleaned, the bottle container rack 3 can be completely removed from the sterilizer body 1, thereby facilitating the cleaning of the interior of the sterilizer.

[0038] In this embodiment, the cross section of the positioning strip 2 is L-shaped. The positioning strip 2 inside the disinfection cabinet has high versatility and can be adapted to the placement of the bottle container rack 3 as well as the dish rack 4 (for placing dishes and other tableware). Figure 10shown.

[0039] In the present invention, the positioning strips 2 are arranged in sequence along the vertical direction inside the disinfection cabinet, and the hot air outlets 1 - 1 are also arranged in sequence along the vertical direction. The arrangement direction of the hot air outlets 1 - 1 is consistent with the arrangement direction of the positioning strips 2 .

[0040] Specifically, the air outlet control mechanism includes a first limiting ring 3-13, a second limiting ring 3-14, a slip ring 3-12, and a top rod 3-6. The first limiting ring 3-13 and the second limiting ring are fixedly arranged in the air outlet pipe 3-3, and the air outlet 3-11 is located between the first limiting ring 3-13 and the second limiting ring 3-14. The slip ring 3-12 is slidably arranged in the air outlet pipe 3-3, and the slip ring 3-12 is located between the first limiting ring 3-13 and the second limiting ring 3-14. A spring is provided between the lower end of the slip ring 3-12 and the second limiting ring 3-14. Spring 3-15; the lower end of the push rod 3-6 is connected to the slip ring 3-12, and the upper end of the push rod 3-6 is higher than the upper end of the air outlet pipe 3-3; when the bottle container 5 is placed upside down on the air outlet pipe 3-3, the push rod 3-6 contacts the bottle container 5, and the slip ring 3-12 is located below the air outlet 3-11 to make the air outlet 3-11 in an open state; when the air outlet pipe 3-3 is in a no-load state, the slip ring 3-12 contacts the first limit ring 3-13, and the slip ring 3-12 blocks the air outlet 3-11 to make the air outlet 3-11 in a closed state.

[0041] The slip ring 3-12 is fitted against the inner wall of the air outlet pipe 3-3, and is connected to the lower end of the push rod 3-6 via a connecting rib 3-19. The upper end of the air outlet pipe 3-3 is provided with a through hole for the push rod 3-6 to pass through. When the bottle container 5 is placed upside down on the air outlet pipe 3-3, the bottom of the bottle container 5 exerts downward pressure on the push rod 3-6 under the action of gravity. The push rod 3-6 drives the slip ring 3-12 to overcome the elastic force of the spring 3-15 and move downward, so that the slip ring 3-12 is separated from the air outlet 3-11 position, and the hot air in the air outlet pipe 3-3 can enter the internal space of the bottle container 5 through the air outlet 3-11; when the bottle container is removed, the spring 3-15 resets and pushes the slip ring 3-12 upward, and the slip ring 3-12 contacts the first limit ring 3-13 and blocks the air outlet 3-11, so that the air outlet 3-11 is in a closed state. This "open when loaded, close when empty" mechanism avoids the waste of hot air resources caused by indiscriminate blowing of hot air in traditional disinfection cabinets.

[0042] The bottle container placement rack 3 includes two air inlet pipes 3-1, and the transition pipes 3-2 on the two air inlet pipes 3-1 are connected by a connecting sleeve 3-7; the two air inlet pipes 3-1 are respectively provided with a shelf plate 3-8; the bottle container placement rack 3 is placed on the positioning bar 2 through the shelf plate 3-8.

[0043] The positioning bar 2 is provided with a positioning hole 2-1, and the lower end of the shelf plate 3-8 is provided with a positioning boss 3-9 that cooperates with the positioning hole 2-1. When the bottle container rack 3 is placed on the positioning bar 2, the positioning boss 3-9 on the shelf plate 3-8 engages with the positioning hole 2-1 on the positioning bar 2. The cooperation between the positioning boss 3-9 and the positioning hole 2-1 limits the axial position of the bottle container rack 3, preventing the bottle container rack 3 from moving axially along the positioning bar 2. In this embodiment, the cross-section of the positioning boss 3-9 is a right-angled trapezoid.

[0044] The air inlet of the air inlet duct 3-1 is provided with a docking tube 3-4, one end of which is provided with a flexible contact cover 3-5. The flexible contact cover 3-5 forms a flexible contact with the surface of the hot air outlet 1-1. When the hot air outlet 1-1 is coupled to the air inlet, the flexible contact cover 3-5 reduces the gap between them, thereby improving the sealing of the coupling, reducing the amount of hot air leaking, and increasing the amount of hot air entering the air inlet duct 3-1. In this embodiment, the flexible contact cover 3-5 is made of fluororubber and can withstand temperatures exceeding 200 degrees Celsius.

[0045] Furthermore, the docking pipe 3-4 is slidably fitted with the air inlet pipe 3-1, and a contact pressure piece 3-18 is provided between the air inlet pipe 3-1 and the docking pipe 3-4; the contact pressure piece 3-18 is arc-shaped, and the contact pressure piece 3-18 includes a first material layer 3-18a and a second material layer 3-18b, the first material layer 3-18a is located on the inner side of the arc of the second material layer 3-18b, and the thermal expansion coefficient of the first material layer 3-18a is greater than the thermal expansion coefficient of the second material layer 3-18b; when the temperature of the contact pressure piece 3-18 rises, the distance between the two ends of the contact pressure piece 3-18 increases.

[0046] The contact pressure piece 3-18 is made of a double-layer material of "high expansion coefficient inner layer + low expansion coefficient outer layer". During drying, as hot air blows in, the contact pressure piece 3-18 will be affected by the hot air and its temperature will rise until it reaches a temperature close to that of the hot air. As the temperature of the contact pressure piece 3-18 rises, the distance between the two ends of the contact pressure piece 3-18 increases, thereby pushing the docking tube 3-4 and the flexible contact cover 3-5 to move toward the hot air outlet 1-1, increasing the contact pressure between the flexible contact cover 3-5 and the surface of the hot air outlet 1-1 (achieving a certain expansion effect), thereby further improving the sealing of the coupling between the hot air outlet 1-1 and the air inlet. When the drying and disinfection is completed, the contact pressure piece 3-18 will gradually cool to room temperature. As the temperature of the contact pressure piece 3-18 drops, the distance between the two ends of the contact pressure piece 3-18 will shorten to the initial state, thereby reducing the contact pressure of the flexible contact cover 3-5 on the surface where the hot air outlet 1-1 is located, thereby facilitating the removal of the bottle container rack 3 from the disinfection cabinet.

[0047] In this embodiment, the first material layer 3 - 18a and the second material layer 3 - 18b are made of metal materials with different thermal expansion coefficients.

[0048] In order to realize the installation of the contact pressure member 3-18, a first connecting portion 3-16 is provided on the inner wall of the air inlet pipe 3-1, and a second connecting portion 3-17 is provided on the inner wall of the docking pipe 3-4. One end of the contact pressure member 3-18 is connected to the first connecting portion 3-16, and the other end of the contact pressure member 3-18 is connected to the second connecting portion 3-17.

[0049] In this embodiment, the air outlets 3-11 are evenly arranged along the circumference of the air outlet pipe 3-3. The evenly distributed air outlets 3-11 allow hot air to be blown out from different angles at the same time, thereby improving the uniformity of the air outlet.

[0050] A method for using a disinfection cabinet comprises the following specific steps: The bottle container rack 3 is taken out of the disinfection cabinet body 1, and the bottle container 5 to be disinfected is placed upside down on the air outlet pipe 3-3 on the bottle container rack 3. After the bottle container 5 is placed, the bottle container rack 3 with the bottle container 5 is installed into the disinfection space in the disinfection cabinet body 1. The shelf plates 3-8 on both sides of the bottle container rack 3 are placed on the positioning strip 2, and the positioning bosses 3-9 at the lower ends of the shelf plates 3-8 are snapped into the positioning holes 2-1 on the positioning strip 2. When the bottle container rack 3 is in place, the air inlet on the air inlet pipe 3-1 is coupled with the hot air outlet 1-1. After the disinfection cabinet starts the drying program, hot air is blown out from the hot air outlet 1-1. The hot air blown out from the hot air outlet 1-1 corresponding to the air inlet passes through the air inlet pipe 3-1, the transition pipe 3-2, the air outlet pipe 3-3 in sequence and is finally blown out from the air outlet 3-11. The hot air blown out from the air outlet 3-11 dries the inside of the bottle container 5.

[0051] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
