[0031] The box body 10 includes a box body 11 and a box cover 12. The box body 11 is hollow inside and has an opening 111 on the top. The opening 111 is used to place transfer items. In one embodiment, the box lid 12 is pivotally connected to one side of the box body 11 and can be rotatably separated from the box body 11 to expose the opening 111 of the box body 11, or be engaged with the box body 11 to cover the opening 111 of the box body 11; two lock buckles 131 are provided on the side walls opposite the pivotal position of the box body 11, and two locking rings 132 are provided on the box lid 12. The locking rings 132 correspond to the lock buckles 131 in position and are equal in number. One lock buckle 131 and one locking ring 132 form a locking structure 13; the box lid 12 is covered at the opening 111 of the box body 11 through the locking structure 13; a sealing strip 15 is provided at the connection between the box body 11 and the box lid 12 when they are engaged, that is, the sealing strip 15 is provided on the four edges of the top opening 111 of the box body 11, or on the four edges of the bottom of the box lid 12. When the box cover 12 is fastened to the box body 11 and locked by the locking structure 13 to maintain the fastened state, the box cover 12 and the box body 11 are tightly against the sealing strip 15 to maintain the sealing of the opening 111 on the transfer device 1 for placing the transferred items.

[0032] In other embodiments of the present application, the opening 111 can also be provided on the side or bottom of the box body 11, and the box cover 12 is pivotally connected to one side of the box body 11, and can be rotatably separated or engaged with the box body 11 at the opening 111; the box cover 12 and the box body 11 can also be in a completely separated state, without being opened and closed by rotation through a pivot structure, and the box cover 12 is directly engaged with the opening 111 of the box body 11 and fixed by a locking structure 13. The locking structure 13 is provided on at least two opposite sides of the box body 10 to ensure that the box body 11 and the box cover 12 are firmly engaged.

[0033] In one embodiment, the lock buckle 131 and the lock ring 132 in the locking structure 13 are made of one or more types of stainless steel (such as 304 or 316), and the box body 11 and the box cover 12 are made of 304 or 316 stainless steel, or other rust-resistant metals of equivalent strength. The entire box body 11 and the box cover 12 and their joints are treated with anti-corrosion and rust-proofing.

[0034] In one embodiment, the sealing strip 15 is made of at least one material, such as rubber or PVC, to ensure the tightness of the transfer device 1. The sealing strip 15 is provided at the connection between the lid 12 and the box body 10. When the transfer device 1 is closed and locked by the locking structure 13, the connection between the lid 12 and the box body 10 is airtight.

[0035] In one embodiment, a handle 14 is further provided on the top of the box 10, and the handle 14 is located in the center of the top of the box 10. The handle 14 facilitates the operator to use the transfer device 1 to transfer items. The operator can easily lift the box 10 by holding the handle 14 to transfer the items placed in the box 10 to the target location.

[0036] The housing 10 has one air inlet 101 and two air outlets 102. In one embodiment, the air outlets 102 are located on either side of the air inlet 101 and on the same side wall of the housing 11 as the air inlet 101. In other embodiments of the present application, there may be one or another number of air outlets 102, and the air outlets 102 may also be located on other side walls of the housing 11, opposite or adjacent to the side wall where the air inlet 101 is located.

[0037] A switch 51, at least one indicator light 52 and a charging port 53 are also provided on the side wall of the box body 10. Figure 2 As shown, an indicator light 52 is provided. In one embodiment, the indicator light 52 is electrically connected to the purification assembly 20 and is used to generate an alarm when the purification assembly 20 inside the transfer device 1 captures excessive dust or kills excessive microorganisms and bacteria. For example, the transfer device 1 lights up green when powered on or in normal operation, and lights up red when in an alarm state.

[0038] In one embodiment, the indicator light 52 can also be connected to the power supply component 54 provided inside the transfer device 1, and prompt the user through different display states (lighting color, flashing or brightness change, etc.) when the power supply component 54 is low on power, the power supply component 54 is charging, or the power supply component 54 is fully charged.

[0039] Switch 51 is connected to power supply 54. When a user presses switch 51, it connects or disconnects the circuit between power supply 54, purification unit 20, and blower 30, thereby turning transfer device 1 on and off. Charging port 53 is connected to power supply 54 and charges power supply 54 when the user connects to an external power source. Charging port 53 can be an existing Type-C port, power connector, or similar.

[0040] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the internal structure of the transfer device 1 shown in an embodiment of the present application. Figures 1 to 3 As shown, a purification component 20 and a fan 30 are provided inside the box body 11 , and the purification component 20 covers the air inlet 101 ; the fan 30 is provided on a side of the purification component 20 away from the air inlet 101 .

[0041] The purification component 20 includes one or more of a filter 21, an electrostatic adsorber 22, or a plasma generator 25. The filter 21 is a primary, medium, and high efficiency filter 21 based on non-woven fabrics, which removes dust particles and microorganisms through physical filtration technology. The electrostatic adsorber 22 is a purification machine that absorbs dust and particulate matter based on high-voltage electrostatic pulses and sterilizes and disinfects based on the temperature generated by the high voltage; the plasma generator 25 simultaneously generates positive ions and negative ions, and neutralizes positive and negative charges in the air, releasing huge energy to change the structure of bacteria in its surrounding environment, causing the bacteria to die, thereby achieving its sterilization effect; in addition, the excess negative ions still float in the environment, which can also achieve the effects of eliminating smoke, dust, and odor.

[0042] like Figures 3 to 5 As shown, the purification assembly 20 includes a filter 21, an electrostatic adsorber 22, and a plasma generator 25. The filter 21 is located on either side of the electrostatic adsorber 22 and plasma generator 25, and the plasma generator 25 covers the air inlet 101, ensuring that all external air entering the transfer device 1 is purified by the purification assembly 20. The electrostatic adsorber 22 and plasma generator 25 are internally divided into a filtration zone, an ionization zone, a particle charging zone, a dust collection zone, and a protective insulation zone. The transfer device 1 contains only one purification assembly 20.

[0043] In other embodiments of the present application, a plurality of purification components 20 may be provided in the transfer device 1 and the plurality of purification components 20 may be connected in parallel or in series; the purification component 20 may select only one or more of the filter 21, the electrostatic adsorber 22 and the plasma generator 25 according to the actual needs of the transfer, or may select other devices with purification functions; the positions of the filter 21, the electrostatic adsorber 22 and the plasma generator 25 may also be set separately according to the purification order and purification requirements.

[0044] The transfer device 1 also includes a power supply 54 connected to the charging port 53. In one embodiment, the power supply 54 utilizes a rechargeable battery, which is sufficient to ensure that the transfer device 1 can perform transfer operations for at least eight hours. The designer can determine the output power of the power supply 54 based on the maximum transfer duration.

[0045] The power supply component 54 is connected to the fan 30, which is used to drive the internal air flow of the transfer device 1. In one embodiment, the power supply component 54 can also be connected to the purification assembly 20. When the purification assembly 20 of the transfer device 1 includes a purification device that requires electricity, such as an electrostatic adsorber 22 or a plasma generator 25, the power supply component 54 needs to be connected to the fan 30 and the purification assembly 20 to continuously provide power while the transfer device 1 is performing the transfer operation.

[0046] In one embodiment, the power supply 54 is a power adapter that outputs a constant voltage or current source. The power supply 54 automatically adjusts its output voltage and current based on the amount of dust accumulated in the purification assembly 20 during purification to maintain the stability of the dust removal efficiency of the purification assembly 20. The indicator light 52 is connected to the power supply 54. When the purification assembly 20 is excessively dusty or in other abnormal conditions, the output current and voltage of the power supply 54 change significantly. The indicator light 52 connected to the power supply 54 can generate an alarm based on the current and voltage changes.

[0047] In one embodiment, a switching valve 23 is provided at the air inlet 101 to control the opening and closing of the air inlet 101. A pressure relief valve 24 is provided at the air outlet 102 to control the opening and closing of the air outlet 102. The switching valve 23 and the pressure relief valve 24 are used to switch the circulating airflow purification mode of the transfer device 1. The circulating airflow purification mode includes an internal circulation airflow purification mode and an external circulation airflow purification mode. The circulating airflow purification mode is selected based on the actual needs of the transferred product.

[0048] In one embodiment, the transfer device 1 further includes at least one placement platform 40, which is provided in the box 10 and is used to place items to be transferred. Figure 3 As shown, only one placement platform 40 is provided. The placement platform 40 is made of one or more stainless steel materials, such as 304 or 316 stainless steel, and its surface is cleaned and treated to prevent rust and corrosion. The specific shape and size of the placement platform 40 are determined by the internal space of the box 10 and the shape and size of the items being transported. The placement platform 40 can be circular, square, or other irregular shapes. In one embodiment, the placement platform 40 is removably attached to the bottom surface of the internal space of the box 10 using a structure such as a clip, screw, or retaining groove. This allows the placement platform 40 and the items to be transported to be reinstalled into the box 10 after the items are removed and placed.

[0049] When the transfer device 1 is in internal circulation airflow purification mode, the switching valve 23 and the pressure relief valve 24 remain closed, allowing the internal circulation airflow within the housing 10 to flow through the purification module, rapidly purifying particulate matter and microorganisms. When the transfer device 1 is in external circulation airflow purification mode, the switching valve 23 and the pressure relief valve 24 remain open, allowing the external circulation airflow to flow through the purification module, purifying particulate matter and killing microorganisms. The pressure relief valve 24, in its connected state, also ensures that the interior of the transfer device 1 maintains a slightly positive pressure, and through the cooperation of the purification assembly 20, prevents pollutants from the external air from entering the transfer device 1.

[0050] Figure 3 The airflow circulation direction shown is the airflow direction when the transfer device 1 is in internal circulation airflow purification mode. When the switch 51 is turned on and the power supply component 54 supplies power to the fan 30 and purification assembly 20, the internal air is driven by the fan 30 to continuously flow. The air inlet 301 of the fan 30 is close to the purification assembly 20, and the air outlet 302 of the fan 30 is away from the purification assembly 20. The air in the internal space of the transfer device 1 is first purified by the purification assembly 20 to remove dust and sterilize. The purified air is then drawn into the air inlet 301 of the fan 30 and blown out of the air outlet 302 of the fan 30. It flows through the items on the placement table 40, removing dust or microorganisms attached to the items' surfaces and promoting the flow of air within the transfer device 1. When the air carrying dust or microorganisms flows again near the purification assembly 20, it is affected by the suction force generated by the operation of the fan 30 and re-enters the purification assembly 20 for purification. The purified air is then blown out by the fan 30 again, achieving continuous cleaning of the transferred items.

[0051] The internal circulation airflow purification mode can ensure that the items placed in the transfer device 1 are continuously cleaned by the flowing purified airflow and will not accumulate dust or microorganisms. The internal gas of the transfer device 1 is continuously purified by the purification component 20 to adsorb particulate matter or sterilize and disinfect. The cleanliness of the transferred items themselves and the surrounding environment is always maintained at a good level, and the transferred items will not be corroded by particulate matter and microorganisms.

[0052] Please refer to Figures 4 and 5 , is a schematic diagram of the internal structure of the transfer device 1 shown in an embodiment of the present application. Figure 4 、 Figure 5 As shown, the internal space of the transfer device 1 can also be provided with a plurality of placement tables 40. Figure 4 There are two placement tables 40 shown. Figure 5 As shown, there are four placement platforms 40. In other embodiments of the present application, the transferred items can also be directly placed in the placement area of ​​the transfer device 1 and fixed or limited by components.

[0053] When transfer device 1 is in external circulation airflow purification mode, switching valve 23 and pressure relief valve 24 are simultaneously open, and the interior of transfer device 1 is connected to the outside world through air inlet 101 and air outlet 102. Transfer device 1 should be set to external circulation airflow purification mode when the items being transferred require a continuous supply of fresh air during transportation.

[0054] Figure 4 、 Figure 5 The airflow circulation direction shown is the airflow direction when the transfer device 1 is in the external circulation airflow purification mode. When the switch 51 is turned on and the power supply component 54 supplies power to the fan 30 and the purification component 20, the switching valve 23 and the pressure relief valve 24 are also opened and connected. Because the air inlet 101 and the air outlet 102 are in the open state, the air inlet 301 of the fan 30 is close to the purification component 20 and the air inlet 101. The outside air enters through the air inlet 101 due to the suction force of the fan 30. After being purified by the purification component 20, it is sucked into the air inlet 301 of the fan 30 and blown out through the air outlet 302. The blown out purified air promotes the flow of air inside the transfer device 1, removes dust and microorganisms on the surface of the transferred items, and provides fresh air conditions for the transferred items. Then, it drives the airflow inside the transfer device 1 to flow out through the air outlet 102. The external circulation airflow purification mode allows external air to enter the transfer device 1 through the air inlet 101 and be continuously purified by the purification component 20. This absorbs dust and particulate matter carried by the external air and kills pathogens and microorganisms. This effectively ensures the cleanliness of the transport environment during the transfer process, protecting the transported items from corrosion by particulate matter and microorganisms. In addition, the external circulation airflow purification mode can also provide oxygen or fresh air to meet higher transport requirements.

[0055] During an operation, an operator enters the cleanroom and opens the transfer device 1. The lid 12 is separated from the box body 10. The operator can then place the transferred items directly into the storage area within the box body 10. Alternatively, the operator can take out the placement table 40 to place the transferred items, and then place the placement table 40 and the transferred items into the box body 10. The lid 12 is then closed onto the box body 11, and the locking ring 132 is locked with the lock buckle 131 to press the lid 12 and the box body 11 against the sealing strip 15.

[0056] Then, based on the transport requirements of the transported items, the operator adjusts the buttons on the box 10 to set the circulating airflow purification mode of the transport device 1. If the transported items require fresh air conditions, the transport device 1 should enter the external circulating airflow purification mode; if the transported items require a closed environment, the transport device 1 should enter the internal circulating airflow purification mode. The operator controls the on and off of the switching valve 23 and the pressure relief valve 24 to directly change the circulating airflow purification mode of the transport device 1. When the switching valve 23 and the pressure relief valve 24 are both open, the air inlet 101 and the air outlet 102 connect the interior of the transport device 1 to the outside world, and the transport device 1 will enter the external circulating airflow purification mode. When the switching valve 23 and the pressure relief valve 24 are closed at the same time, and the air inlet 101 and the air outlet 102 are sealed, the transport device 1 will enter the internal circulating airflow purification mode.

[0057] Finally, the operator turns on switch 51 to connect the power supply 54 to the purification unit 20 and fan 30, and the transfer device 1 begins its transfer operation, i.e., the corresponding circulating airflow purification operation. The operator then lifts handle 14 on the top of the housing 10 to move the transfer device 1 to the target location. Upon reaching the target location, the operator turns off switch 51, closes the switching valve 23 and the pressure relief valve 24, and stops the fan 30 and purification unit 20. The operator then opens the housing lid 12 to remove the items being transferred.

[0058] In one embodiment, the switch 51 can be electrically connected to the switching valve 23 and the pressure relief valve 24 based on actual needs. When the operator adjusts the switch 51 to the external circulation purification position, the fan 30 and the purification component 20 are connected to the power supply component 54 and begin to operate, and the switching valve 23 and the pressure relief valve 24 are synchronously opened. When the operator adjusts the switch 51 to the internal circulation purification position, the fan 30 and the purification component 20 are connected to the power supply component 54 and begin to operate, and the pressure relief valve 24 and the switching valve 23 are synchronously closed. When the operator adjusts the switch 51 to the off position, the circuit between the fan 30, the purification component 20, and the power supply component 54 is disconnected, and the pressure relief valve 24 and the switching valve 23 enter the off state.

[0059] In one embodiment, the fan 30 of the transfer device 1 provided herein should be configured with an appropriate operating power to ensure that the airflow velocity in both the internal and external circulation airflow purification modes does not exceed 3 m / s. This further ensures that the purification component 20 can adequately capture particulate matter and dust and effectively kill microorganisms and pathogens. When the airflow velocity does not exceed 3 m / s, the purification component 20 has a particle purification efficiency of ≥90% and a microbial kill rate of ≥80%.

[0060] The transfer device 1 provided in the present application has an active purification function. Regardless of whether the air in the internal environment or the external environment of the transfer device 1 carries particulate matter, dust, germs, or microorganisms, the device can actively capture particulate matter or perform sterilization and disinfection and other purification work through the internal circulation airflow purification mode or the external circulation airflow purification mode to ensure that the transferred items in the transfer device 1 are always in a clean environment, and continuously supply purified fresh air when needed.

[0061] The transfer device 1 provided by the present application realizes the internal circulation purification work and the external circulation purification work of the articles during the transfer process through the purification component 20 and the fan 30 provided inside, as well as the air inlet 101 and the air outlet 102 provided on the side wall, and provides purified fresh air for articles that require a fresh air environment, effectively preventing the articles from being contaminated by dust or germs before, during, and after transfer. The present application effectively improves the transfer efficiency and transfer quality of articles, and can achieve the functions of maintaining the fresh air environment and sterilizing and removing dust for the transferred articles through a simple structure, while ensuring the surface cleanliness of the transferred articles and improving the user experience.

[0062] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application.
