Description

Technical Field

[0001] This invention relates to the field of disinfection cabinet technology, and in particular to a disinfection cabinet and its usage method. Background Technology

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

[0003] Existing disinfection cabinets are 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 at about 120 degrees Celsius. The hot air is blown into the disinfection space inside the disinfection cabinet through the hot air outlet, and the items are dried by the hot air.

[0004] However, when existing disinfection cabinets dry some bottle containers, the internal surfaces of these containers often retain a significant amount of moisture after washing. Furthermore, the relatively enclosed space within these containers results in poor air circulation, making it difficult for the hot air from the disinfection cabinet to reach the interior directly. This leads to a slower drying speed on the internal surfaces of the bottles, requiring the disinfection cabinet to set a longer drying time. This increases the overall time required for the drying and disinfection process and also increases energy consumption. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art and provide a disinfection cabinet and its usage method.

[0006] The objective of this invention is achieved through the following technical solution: a disinfection cabinet, comprising a disinfection cabinet body and a bottle container rack, wherein a disinfection space is provided inside the disinfection cabinet body, and a positioning strip is fixedly provided inside the disinfection space, and the bottle container rack is placed in the disinfection space and rests on the positioning strip; a hot air outlet is provided on one side of the disinfection space, and the hot air outlets are arranged in a straight line.

[0007] The bottle container rack includes an air inlet pipe, several transition pipes on the air inlet pipe, several air outlet pipes on the transition pipes, and air outlets on the air outlet pipes. The air outlet pipes are equipped with an air outlet control mechanism for controlling the opening and closing of the air outlets. When the bottle container is inverted on the air outlet pipe, the air outlet is in the open state. When the air outlet pipe is in an unloaded state, the air outlet is in the closed state.

[0008] One end of the air inlet pipe is the air inlet; when the bottle container rack is placed in the disinfection space, the air inlet on the air inlet pipe is coupled with the hot air outlet so that the hot air blown out from the hot air outlet enters the air inlet pipe.

[0009] Preferably, the air outlet control mechanism includes a first limiting ring, a second limiting ring, a slip ring, and a push rod. The first and second limiting rings are fixedly installed inside the air outlet pipe, and the air outlet is located between the first and second limiting rings. The slip ring is slidably installed inside the air outlet pipe, and is located between the first and second limiting rings. 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 pipe. When a bottle is placed upside down on the air outlet pipe, the push rod contacts the bottle, and the slip ring is located below the air outlet so that the air outlet is in an open state. When the air outlet pipe is in an unloaded state, the slip ring contacts the first limiting ring, and the slip ring blocks the air outlet so that the air outlet is in a closed state.

[0010] Preferably, the bottle container rack includes two air inlet pipes, and the transition pipes on the two air inlet pipes are connected by a connecting sleeve; each of the two air inlet pipes is provided with a shelf; the bottle container rack is placed on the positioning strip by the shelf.

[0011] Preferably, the positioning strip is provided with positioning holes, and the lower end of the shelf is provided with a positioning boss that mates with the positioning holes.

[0012] Preferably, the air inlet of the air inlet pipe is provided with a connecting pipe, and one end of the connecting pipe is provided with a flexible contact cover.

[0013] Preferably, the connecting pipe and the air inlet pipe are slidably fitted together, and a contact pressure-applying component is provided between the air inlet pipe and the connecting pipe; the contact pressure-applying component is arc-shaped and includes a first material layer and a second material layer, the first material layer is located inside the arc of the second material layer, and the thermal expansion coefficient of the first material layer is greater than that of the second material layer; when the temperature of the contact pressure-applying component rises, the distance between the two ends of the contact pressure-applying component increases.

[0014] Preferably, the inner wall of the air inlet pipe is provided with a first connecting part, the inner wall of the connecting pipe is provided with a second connecting part, one end of the contact pressure member is connected to the first connecting part, and the other end of the contact pressure member is connected to the second connecting part.

[0015] Preferably, the air outlets are evenly arranged along the circumference of the air outlet duct.

[0016] Preferably, the cross-section of the positioning strip is "L" shaped.

[0017] A method for using a disinfection cabinet includes the following specific steps:

[0018] Remove the bottle container rack from the main body of the sterilizer. Place the bottles to be sterilized upside down on the air outlet duct of the bottle container rack. After placing the bottles, insert the bottle container rack into the sterilization space inside the main body of the sterilizer. Place the shelves on both sides of the bottle container rack on the positioning strip and make the positioning protrusions at the bottom of the shelves engage with the positioning holes on the positioning strip. After the bottle container rack is in place, the air inlet on the air inlet duct couples with the hot air outlet.

[0019] After the sterilizer 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, the transition pipe, and the air outlet pipe in sequence, and finally blown out from the air outlet. The hot air blown out from the air outlet dries the inside of the bottled containers.

[0020] The beneficial effects of this invention are:

[0021] 1. In this invention, when drying bottle containers, the bottle containers are placed upside down on the air outlet pipe, with the air outlet on the air outlet pipe extending into the internal space of the bottle containers. During the drying process, the hot air blown out from the hot air outlet that is not coupled to the air inlet is directly blown into the disinfection space inside the disinfection cabinet body. This portion of the hot air is blown towards the outer surface of the bottle containers, directly drying the outer surface. Meanwhile, the hot air blown out from the hot air outlet coupled to the air inlet enters the air inlet pipe, then passes through the transition pipe and the air outlet pipe in sequence, and finally exits from the air outlet. The hot air blown out from the air outlet is blown into the bottle containers, thereby drying the inside of the bottle containers. This invention can effectively introduce hot air into the interior of bottle containers during drying, greatly accelerating the airflow and drying speed inside the bottle containers, thereby shortening the entire drying and disinfection process time and saving energy consumption.

[0022] 2. An air outlet control mechanism is installed on the air outlet duct, which can automatically adjust the air outlet status: when a bottle container is inverted on the air outlet duct, the air outlet opens, and the hot air is precisely applied to the bottle container; when the air outlet duct is unloaded, the air outlet closes to prevent the hot air from spreading aimlessly into the disinfection space; in this way, all the hot air entering the air inlet duct can be distributed to the internal space of the bottle container that needs to be dried, improving the utilization rate of hot air and achieving the design purpose of air outlet on demand.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0035] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0036] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0037] like Figures 1 to 10 As shown, a disinfection cabinet includes a cabinet body 1 and a bottle / container rack 3. The cabinet body 1 has a disinfection space, and a positioning strip 2 is fixedly installed in the disinfection space. The bottle / container 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 rack 3 includes an air inlet pipe 3-1, a plurality of transition pipes 3-2 are provided on the air inlet pipe 3-1, and a plurality of air outlet pipes 3-3 are provided on the transition pipes 3-2. An air outlet 3-11 is provided on the air outlet pipe 3-3. An air outlet control mechanism is provided on the air outlet pipe 3-3 to control the opening and closing of the air outlet 3-11. When the bottle / container 5 is inverted 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.

[0038] One end of the air inlet pipe 3-1 is the air inlet; when the bottle container 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.

[0039] The air inlet pipe 3-1, transition pipe 3-2, and air outlet pipe 3-3 are interconnected, allowing air to flow sequentially through them. When the bottle container rack 3 is placed in the disinfection space, the air inlet pipe 3-1 and transition pipe 3-2 are horizontal, while the air outlet pipe 3-3 is vertical.

[0040] In this invention, when drying bottle-type containers 5, the bottle-type containers 5 are 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 internal space of the bottle-type containers 5. During the drying process, the hot air blown out from the hot air outlet 1-1, which is not coupled to the air inlet, will be directly blown into the disinfection space inside the disinfection cabinet body 1. This portion of the hot air will be blown towards the outer surface of the bottle-type containers 5, directly drying the outer surface of the bottle-type containers 5. The hot air blown out from the hot air outlet 1-1, which is coupled to the air inlet, will... The hot air enters the inlet pipe 3-1, then passes through the transition pipe 3-2 and the outlet pipe 3-3, and finally exits through the outlet 3-11. The hot air blown out from the outlet 3-11 is then blown into the bottle container 5, thereby drying the inside of the bottle container 5. This invention effectively introduces hot air into the interior of the bottle container 5 during drying, greatly accelerating the airflow and drying speed, thus shortening the overall drying and disinfection process and saving energy. In contrast, in traditional disinfection cabinet technology, hot air is difficult to penetrate the inner wall of the bottle container 5 during drying, resulting in a longer overall drying time and higher energy consumption.

[0041] An air outlet control mechanism is installed on the air outlet duct 3-3. The air outlet control mechanism on the air outlet duct 3-3 can automatically adjust the air outlet state of the air outlet 3-11: when the bottle container 5 is inverted on the air outlet duct 3-3, the air outlet 3-11 opens, and the hot air is precisely applied to the bottle container 5; when the air outlet duct 3-3 is unloaded, the air outlet 3-11 closes to prevent the hot air from spreading aimlessly into the disinfection space. In this way, all the hot air entering the air inlet duct 3-1 can be distributed to the internal space of the bottle container that needs to be dried, which improves the utilization rate of hot air and achieves the design purpose of air outlet on demand.

[0042] The bottle container rack 3 in this invention features a fully detachable design. When sterilizing bottle containers 5, the rack 3 can be removed from the sterilizer, and the bottles 5 to be sterilized can be placed one by one onto the rack 3. Once full, the rack 3 can be placed back into the sterilizer. This detachable design allows users to remove the rack from the sterilizer and load the bottle containers 5 individually, avoiding the need to place them one by one in a confined sterilization space. This is especially suitable for loading a large number of containers or containers with tall bodies (such as baby bottles and thermos cups), reducing operational difficulty. Furthermore, when cleaning the inside of the sterilizer is required, the bottle container rack 3 can be completely removed from the sterilizer body 1, facilitating cleaning of the inside of the sterilizer.

[0043] In this embodiment, the positioning strip 2 has an "L"-shaped cross-section. The positioning strip 2 inside the disinfection cabinet has high versatility, adapting to both the bottle container rack 3 and the dish rack 4 (for placing bowls, plates, and other tableware), such as... Figure 10As shown.

[0044] In this invention, the positioning strips 2 are arranged sequentially along the vertical direction inside the disinfection cabinet, and the hot air outlets 1-1 are also arranged sequentially 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.

[0045] 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 push rod 3-6. The first limiting ring 3-13 and the second limiting ring are fixedly installed inside the air outlet pipe 3-3. 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 installed inside the air outlet pipe 3-3, 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 3-3; When the bottle container 5 is placed upside down on the air outlet 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 so that the air outlet 3-11 is in the open state; When the air outlet 3-3 is in the unloaded state, the slip ring 3-12 contacts the first limiting ring 3-13, and the slip ring 3-12 blocks the air outlet 3-11 so that the air outlet 3-11 is in the closed state.

[0046] The slip ring 3-12 fits against the inner wall of the air outlet 3-3, and is connected to the lower end of the top rod 3-6 via a connecting rib 3-19. The upper end of the air outlet 3-3 has a through hole for the top rod 3-6 to pass through. When the bottle container 5 is inverted on the air outlet 3-3, the bottom of the bottle container 5 presses down on the top rod 3-6 under gravity. The top rod 3-6 causes the slip ring 3-12 to move downwards against the spring force of the spring 3-15, disengaging the slip ring 3-12 from the air outlet 3-11. Hot air from the air outlet 3-3 can then enter the internal space of the bottle container 5 through the air outlet 3-11. When the container is removed, the spring 3-15 resets and pushes the slip ring 3-12 upwards. The slip ring 3-12 contacts the first limiting ring 3-13 and blocks the air outlet 3-11, keeping the air outlet 3-11 closed. This "load and turn on, empty and turn off" mechanism avoids the waste of hot air resources caused by the indiscriminate blowing of hot air in traditional disinfection cabinets.

[0047] The bottle container 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; each of the two air inlet pipes 3-1 is provided with a shelf 3-8; the bottle container rack 3 is placed on the positioning strip 2 by the shelf 3-8.

[0048] The positioning strip 2 has a positioning hole 2-1, and the lower end of the shelf 3-8 has a positioning boss 3-9 that mates with the positioning hole 2-1. When the bottle container rack 3 is placed on the positioning strip 2, the positioning boss 3-9 on the shelf 3-8 engages with the positioning hole 2-1 on the positioning strip 2. Through the engagement between the positioning boss 3-9 and the positioning hole 2-1, the bottle container rack 3 is axially limited, preventing it from moving along the axial direction of the positioning strip 2. In this embodiment, the cross-section of the positioning boss 3-9 is a right-angled trapezoid.

[0049] A connecting pipe 3-4 is provided in the air inlet of the air inlet duct 3-1, and a flexible contact cover 3-5 is provided at one end of the connecting pipe 3-4. The flexible contact cover 3-5 will form a flexible contact with the surface where the hot air outlet 1-1 is located. When the hot air outlet 1-1 is coupled with the air inlet, the flexible contact cover 3-5 can reduce the gap between the two, thereby improving the sealing of the coupling, reducing the leakage of hot air, 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, which can withstand high temperatures above 200 degrees Celsius.

[0050] Furthermore, the connecting pipe 3-4 and the air inlet pipe 3-1 are slidably fitted together, and a contact pressure member 3-18 is provided between the air inlet pipe 3-1 and the connecting pipe 3-4; the contact pressure member 3-18 is arc-shaped, and the contact pressure member 3-18 includes a first material layer 3-18a and a second material layer 3-18b. The first material layer 3-18a is located inside the arc of the second material layer 3-18b, and the coefficient of thermal expansion of the first material layer 3-18a is greater than that of the second material layer 3-18b; when the temperature of the contact pressure member 3-18 rises, the distance between the two ends of the contact pressure member 3-18 increases.

[0051] The contact pressure element 3-18 is made of a double-layer material with a high expansion coefficient inner layer and a low expansion coefficient outer layer. During drying, as hot air is blown in, the contact pressure element 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 element 3-18 rises, the distance between the two ends of the contact pressure element 3-18 increases, thereby pushing the connecting pipe 3-4 and the flexible contact cover 3-5 to move towards the hot air outlet 1-1. This increases the contact pressure between the flexible contact cover 3-5 and the surface of the hot air outlet 1-1 (achieving a certain tightening effect), thereby further improving the sealing performance of the coupling between the hot air outlet 1-1 and the air inlet. After drying and sterilization are completed, the contact pressure component 3-18 will gradually cool down to room temperature. As the temperature of the contact pressure component 3-18 decreases, the distance between the two ends of the contact pressure component 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, thus facilitating the removal of the bottle container rack 3 from the sterilization cabinet.

[0052] In this embodiment, the first material layer 3-18a and the second material layer 3-18b are made of metal materials with different coefficients of thermal expansion.

[0053] In order to install the contact pressure member 3-18, a first connecting part 3-16 is provided on the inner wall of the air inlet pipe 3-1, and a second connecting part 3-17 is provided on the inner wall of the connecting pipe 3-4. One end of the contact pressure member 3-18 is connected to the first connecting part 3-16, and the other end of the contact pressure member 3-18 is connected to the second connecting part 3-17.

[0054] In this embodiment, the air outlets 3-11 are evenly arranged along the circumference of the air outlet duct 3-3. The evenly distributed air outlets 3-11 allow hot air to be blown out from different angles simultaneously, improving the uniformity of airflow.

[0055] A method for using a disinfection cabinet includes the following specific steps:

[0056] Remove the bottle container rack 3 from the disinfection cabinet body 1, and place the bottle container 5 to be disinfected upside down on the air outlet duct 3-3 on the bottle container rack 3. After the bottle container 5 is placed, insert the bottle container rack 3 containing the bottle container 5 into the disinfection space inside the disinfection cabinet body 1. The shelf plates 3-8 on both sides of the bottle container rack 3 rest on the positioning strip 2, and make the positioning protrusion 3-9 at the lower end of the shelf plate 3-8 engage with the positioning hole 2-1 on the positioning strip 2. When the bottle container rack 3 is in place, the air inlet on the air inlet duct 3-1 is coupled with the hot air outlet 1-1.

[0057] After the sterilizer 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, which is corresponding to the air inlet, passes through the air inlet pipe 3-1, the transition pipe 3-2, the air outlet pipe 3-3 and 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.

[0058] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
