[0056] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] like Figure 1 - Figure 5 As shown, the disinfection cabinet provided by the present invention comprises a cabinet body, a door body 1, a baffle assembly and a driving mechanism. The door body 1 and the cabinet body can be rotatably connected or slidably connected to realize the opening and closing of the door body 1.

[0058] like Figure 3 As shown, the cabinet includes a disinfection cavity 42 and a thermal circulation mechanism, and the thermal circulation mechanism is connected to the disinfection cavity 42 and is used to generate a thermal circulation airflow in the disinfection cavity 42. That is, the thermal circulation mechanism can both generate a circulating airflow and heat the circulating airflow, and the airflow circulation function and the heating function can be performed separately or simultaneously.

[0059] The door body 1 is provided with an exhaust passage connecting the inner and outer sides thereof. The baffle assembly is movably connected to the door body 1, and the driving mechanism is connected to the door body 1 and the baffle assembly, and is used to drive the baffle assembly to switch between a first state, a second state and a third state relative to the door body 1.

[0060] like Figure 3 As shown, when the baffle assembly is in the first state, the exhaust passage is closed by the baffle assembly, and the gas in the disinfection chamber 42 cannot be discharged.

[0061] like Figure 4 As shown, when the baffle assembly is in the second state, the exhaust channel is open and the flow rate is L1. At this time, the opening of the exhaust channel is small, which is only enough to discharge water vapor, and the user's hand cannot be inserted into the exhaust channel.

[0062] like Figure 5As shown, when the baffle assembly is in the third state, the exhaust channel is opened and the flow rate is L2, and L2 is greater than L1. At this time, the opening of the exhaust channel is relatively large, and the opening edge of the exhaust channel located on the outer side of the door body 1 forms a handle 6 for the user to insert his hand. The user can put his hand into it to control the movement of the door body 1 relative to the cabinet body.

[0063] Initially, the door body 1 closes the disinfection cavity 42, the baffle assembly is in the first state, the user can turn on the drying function of the disinfection cabinet, and the thermal circulation mechanism starts to work; at this time, under the action of the thermal circulation mechanism, the hot air flow inside the disinfection cavity 42 presents the form of internal circulation. The temperature in the disinfection cavity 42 gradually increases. When the temperature in the disinfection cavity 42 is higher than the ambient temperature of the outside to a first temperature difference value, water vapor begins to be generated in the disinfection cavity 42. At this time, the driving mechanism can be controlled to drive the baffle assembly to switch from the first state to the second state. At this time, the exhaust channel opens a gap, but the gap is only used for water vapor to flow outward, which is not enough for the user's hand to reach in. At this time, the hot air flow in the disinfection cavity 42 is transformed into an external circulation, and the hot air drives the water vapor to be discharged from the gap of the exhaust channel to the outside. After the first time period, the water vapor in the disinfection cavity 42 is almost completely discharged; the driving mechanism can switch the baffle assembly back to the first state again, the exhaust channel is closed, and the hot air flow form of the internal circulation is restored in the disinfection cavity 42, waiting until the drying working time ends. When it is completely finished, the driving mechanism drives the baffle assembly to move to the third state, and the opening of the exhaust channel is larger than that of the second state. At this time, the opening size can fully meet the user's hand insertion, and the user pulls the handle 6 of the door body 1 to open the door body 1. By controlling the baffle assembly to switch to different states, the timing of the external circulation can be controlled, and the water vapor in the disinfection cavity 42 can be effectively removed, so that the drying effect is better.

[0064] like Figure 3 As shown, the thermal circulation mechanism includes an air duct cavity 43 and a circulating fan 44, and the air duct cavity 43 is connected to the outer wall of the disinfection cavity 42; the disinfection cabinet is provided with an air inlet channel and an air outlet channel connecting the air duct cavity 43 and the disinfection cavity 42; and the air inlet channel and the exhaust channel are both located above the air outlet channel; the circulating fan 44 is located in the air duct cavity 43, and is used to generate an airflow from the air inlet channel to the air outlet channel in the air duct cavity 43.

[0065] The air duct cavity 43 can be installed at the rear side of the disinfection cavity 42, and the circulating fan 44 is installed above the air duct cavity 43, close to the air inlet channel. The airflow generated by the circulating fan 44 after starting can enter the disinfection cavity 42 from top to bottom through the air outlet channel. Negative pressure is formed above the air duct cavity 43, and the gas in the disinfection cavity 42 will enter the air duct cavity 43 through the air inlet channel under the action of the negative pressure.

[0066] The air duct cavity 43 is a cylindrical structure, which can be enclosed by itself, or can cover the back plate of the disinfection cavity 42 to form a closed space.

[0067] In this embodiment, the thermal cycle mechanism further includes a heating device 45, which is located in the disinfection cavity 42 and outside the opening of the air outlet channel, and the gas blown out from the air outlet channel is heated by the heating device 45 and then enters the disinfection cavity 42. In other feasible solutions, the heating device 45 can also be located in the air duct cavity 43 and outside the opening of the air outlet channel, and the airflow is heated before being blown into the disinfection cavity 42.

[0068] Secondly, the heating device 45 can be distributed in the bottom plate or door plate of the disinfection chamber 42 to provide auxiliary heating. In other words, the number of the heating devices 45 can be two, and the heating device 45 can also be arranged on the bottom plate of the disinfection chamber 42 near the door plate, so as to avoid the problem that the temperature of the airflow circulating to the door body 1 is lower than the temperature of the airflow on the back plate side, resulting in a large temperature difference between the front and the back.

[0069] From top to bottom, the cross-sectional area of ​​the air duct cavity 43 gradually decreases, which is conducive to forming a high-speed airflow at the outlet.

[0070] like Figure 6 and Figure 7 As shown, the door body 1 includes an outer door panel 2 and an inner door panel 33 which are arranged in parallel and at intervals, and the baffle assembly includes a first baffle 3 and a second baffle 35 .

[0071] The outer door plate 2 and the inner door plate 33 are arranged in parallel and at intervals, with a gap between them, and the gap is sealed all around. The first baffle plate 3, the second baffle plate 35 and the driving mechanism can all be arranged in the gap.

[0072] The outer door panel 2 is provided with a first opening 5, and the first baffle 3 is rotatably connected to the outer door panel 2; the inner door panel 33 is provided with a second opening 34, and the second baffle 35 is slidably connected to the outer door panel 2, and the first opening 5 and the second opening 34 are connected to form the exhaust passage.

[0073] The first baffle plate 3 switches among the first position, the second position and the third position by rotating forward and backward, and the second baffle plate 35 switches among the third position, the fourth position and the fifth position by sliding up and down.

[0074] like Figure 7As shown, when the baffle assembly is in the first state, the first baffle 3 is in the first position, and the first baffle 3 is located in the first opening 5, and the front of the first baffle 3 is in the same plane as the front of the outer door panel 2, the first baffle 3 closes the first opening 5, and from the outside, the first baffle 3 and the outer door panel 2 form a whole, which is beautiful and convenient to wipe, and will not accidentally bump the user. The second baffle 35 is in the fourth position, and the second baffle 35 blocks the second opening 34, and the water vapor in the disinfection cavity 42 will not leak.

[0075] When the baffle assembly is in the second state, the first baffle 3 is in the second position, the first baffle 3 is at least partially located at the rear side of the first opening 5, and the opening of the first opening 5 is K11. After the first baffle 3 rotates inward by an angle, it switches from the first position to the second position, and the first opening 5 opens a small gap. At this time, the user's hand cannot reach into the exhaust channel through the first opening 5. At the same time, the second baffle 35 is in the fifth position, the second opening 34 is opened, and the opening is K21. After the second opening 34 is opened, the water vapor in the disinfection cavity 42 can be discharged after passing through the second opening 34 and the first opening 5.

[0076] like Figure 8 As shown, when the baffle assembly is in the third state, the first baffle 3 is in the third position, the first baffle 3 is at least partially located at the rear side of the first opening 5, and the opening of the first opening 5 is K12, K12 is greater than K11, so that the edge of the first opening 5 forms a gripping portion 6, that is, when the first baffle 3 is in the third position, the first opening 5 is opened wider, allowing the user's hand to reach in, and the user can hold the outer door panel 2 with his hand to push and pull the door body 1. At the same time, the second baffle 35 is in the sixth position, the second opening 34 is open, and the opening is K22, K22 is greater than K21, and the second opening 34 can be fully opened to accelerate the discharge of steam and prevent steam from spraying toward the user when the door body 1 is opened.

[0077] like Figure 7 As shown, the first baffle plate 3 and the second baffle plate 35 are correspondingly provided with a pushing structure, and the driving end of the driving mechanism is connected to the first baffle plate 3, so that when the driving mechanism drives the first baffle plate 3 to switch among the first position, the second position and the third position, the pushing structure drives the second baffle plate 35 to switch among the fourth position, the fifth position and the sixth position at the same time; an elastic return member 17, such as a spring, is provided between the inner door panel 33 and the second baffle plate 35, and the elastic return member 17 is used to make the second baffle plate 35 have a tendency to move toward the fourth position.

[0078] The movement of the first baffle plate 3 can be transmitted to the second baffle plate 35 through the pushing structure, so that the first baffle plate 3 and the second baffle plate 35 can be switched at the same time by using one driving mechanism. The linkage design is ingenious, the number of driving mechanisms is reduced, and the cost is reduced. At the same time, when the first baffle plate 3 no longer applies pressure to the second baffle plate 35, the second baffle plate 35 returns to the fourth position under the elastic force of the elastic reset member 17.

[0079] Specifically, the pushing structure includes a push arm 36 disposed on the back of the first baffle 3, and the push arm 36 can be arc-shaped or right-angled. The front of the second baffle 35 has a first limit seat 37 protruding forward, and the first limit seat 37 is located on the movement path of the push arm 36. The upper surface of the first limit seat 37 can abut against the push arm 36. The push arm 36 pushes the first limit seat 37, thereby driving the second baffle 35 to move downward, and the inner door panel 33 is provided with a second limit seat 38 located below the first limit seat 37. The first limit seat 37 and the second limit seat 38 are both provided with columns on the surfaces facing each other, and the two ends of the elastic reset member 17 are inserted into the columns, so as to prevent the elastic reset member 17 from deviating.

[0080] like Fig. 9 - Fig.11 As shown, the door body 1 further includes a connecting bracket 4 and a connecting rod 14. The connecting bracket 4 includes a rotating seat 7 and a rotating frame 8, the rotating seat 7 is connected to the outer door panel 2, and the rotating frame 8 is connected to the first baffle 3; one end of the connecting rod 14 is rotatably connected to the rotating frame 8, and the other end is connected to the driving mechanism. In this embodiment, the driving mechanism includes a push rod motor 13, and a push rod of the push rod motor 13 is rotatably connected to the connecting rod 14.

[0081] An axial hole 9 is provided on the rotating seat 7, and a first rotating shaft 10 connected to the axial hole 9 is provided on the rotating frame 8. The rotating seat 7 and the outer door panel 2 can be connected by adhesive, or by using a threaded member, such as a screw. Similarly, the rotating frame 8 and the first baffle 3 can be connected in the same way. The first rotating shaft 10 extends in the left-right direction. The rotating seat 7 includes two parallel and opposite side panels, each of which is provided with an axial hole 9. The first rotating shaft 10 is located between the two axial holes 9, and one end of the first rotating shaft 10 is connected to one of the axial holes 9, and the other end is connected to the other axial hole 9. The rotating frame 8 is connected through the two side panels, and the connection stability is better.

[0082] The rotating frame 8 is provided with a second rotating shaft 12 , the rotating seat 7 is provided with an arc guide groove 11 , the center of the arc guide groove 11 is located on the axis of the shaft hole 9 , and the second rotating shaft 12 is slidably connected to the arc guide groove 11 .

[0083] The second rotating shaft 12 is arranged parallel to the first rotating shaft 10, and an arc guide groove 11 is arranged on each side plate. The second rotating shaft 12 on the rotating frame 8 can slide along the arc guide groove 11, and the arc guide groove 11 guides and limits the rotating frame 8, so that the rotating frame 8 only rotates around the first rotating shaft 10.

[0084] like Figure 7 As shown, the door body 1 further includes a surrounding plate 39 arranged around the outside of the first opening 5 and the second opening 34 , one end of the surrounding plate 39 is connected to the outer door panel 2 , and the other end of the surrounding plate 39 is connected to the inner door panel 33 .

[0085] In this embodiment, the enclosure 39 can be perpendicular to the outer door panel 2 and the inner door panel 33 respectively, and the enclosure 39 surrounds both the first opening 5 and the second opening 34, so that when the first opening 5 and the second opening 34 are both opened, the steam in the cavity can be discharged from the first opening 5 along the channel surrounded by the enclosure 39, thereby reducing the overflow of steam inside the door body 1 and causing water accumulation in the door body 1.

[0086] The enclosure 39 can be in a fully enclosed form, that is, completely enclosed the drive mechanism, or in a semi-enclosed form, that is, enclosed the upper part, left side and right side of the first opening 5, and open at the bottom to leave space for the drive mechanism.

[0087] The enclosure 39 is provided with a slide groove extending along the sliding direction of the second baffle plate 35, the number of the slide grooves is two, the openings of the two slide grooves face each other, the second baffle plate 35 is located between the two slide grooves and is slidably connected to the slide grooves.

[0088] The left and right sides of the second baffle 35 are both located in the slide groove. Under the limiting effect of the slide groove, the second baffle 35 is prevented from moving in the front-back direction, making its movement more stable.

[0089] A limiting groove 41 is provided on the enclosure 39 , and the limiting groove 41 is located on the sliding path of the second baffle plate 35 and opens toward the second baffle plate 35 ; when the second baffle plate 35 is located at the third position, the upper edge of the second baffle plate 35 is located in the limiting groove 41 .

[0090] The limiting groove 41 is located above the second baffle plate 35. When the elastic reset member 17 drives the second baffle plate 35 to reset upward, the upper edge of the second baffle plate 35 can enter the limiting groove 41 and stop moving after abutting against the bottom of the limiting groove 41. On the one hand, the limiting groove 41 plays a limiting role, and on the other hand, it can also improve the sealing. When the second baffle plate 35 is in the third position, it reduces the steam in the cavity from entering the door body 1.

[0091] like Fig. 9As shown, the disinfection cabinet includes a door frame 20, and a lock hole 21 is arranged on the door frame 20; the door body 1 also includes a linkage assembly and a lock pin 19, and the lock pin 19 cooperates with the lock hole 21; the linkage assembly is connected to the driving mechanism and the lock pin 19 respectively, and when the linkage assembly is in the first state and the second state, the lock pin 19 moves to the locked state driven by the linkage assembly; when the linkage assembly is in the third state, the lock pin 19 moves to the open state driven by the linkage assembly.

[0092] In order to improve the safety of the door body 1 and prevent children from accidentally opening the door body 1, a lock pin 19 can be provided on the door body 1, and a lock hole 21 can be provided on the door frame 20. The lock pin 19 is linked with the baffle assembly. When the device is working, that is, when the baffle assembly is in the first state and the second state, the lock pin 19 switches to the locked state, and the lock pin 19 is inserted into the lock hole 21. When the door body 1 needs to be opened, that is, when the baffle assembly is in the third state, the first baffle 3 switches to the third position, the grip portion is exposed, the lock pin 19 switches to the open state, and the user can open the door body 1.

[0093] The linkage assembly includes a first rack 22 extending in the up-down direction, a steering gear and a second rack 25 extending in the left-right direction, the first rack 22 and the second rack 25 are both engaged with the steering gear; the first rack 22 is connected to the driving end of the driving mechanism; the locking pin 19 is connected to the second rack 25.

[0094] The first rack 22 is connected to the push rod through a horizontal bar extending left and right. The push rod can drive the first rack 22 to move in the up and down directions. Then the first rack 22 pulls the steering gear to rotate, and the steering gear drives the second rack 25 to move in the left and right directions. The locking pin 19 connected to the second rack 25 also moves in the left and right directions, thereby realizing the switching between the unlocking and locking states.

[0095] Further, the number of the lock pins 19 is two, and the two lock pins 19 are symmetrically arranged. That is to say, the push rod can simultaneously drive the two symmetrical lock pins 19 to move toward or relative to each other, so that when the door body 1 is in a locked state, it is more tightly connected to the door frame 20.

[0096] The steering gear includes a first gear 23 and a second gear 24 arranged side by side in the axial direction. In order to avoid interference between the first rack 22 and the second rack 25, the first rack 22 can be arranged to mesh with the first gear 23, and the second rack 25 can be arranged to mesh with the second gear 24. The diameter ratio of the first gear 23 and the second gear 24 can be the same or different.

[0097] like Fig.12As shown, the locking pin 19 includes a connecting portion 27 and a locking tongue 26 . The locking tongue 26 is slidably connected to the connecting portion 27 , and a floating spring 30 is provided therebetween. The connecting portion 27 is connected to the second rack 25 .

[0098] The lock tongue 26 can be retracted and floated relative to the connection part 27, that is, even if the lock pin 19 is in the locked state, when an external force is applied to the lock tongue 26 in the left and right directions, the lock tongue 26 can compress the floating spring 30 and move toward the side close to the connection part 27, and after the external force is removed, the lock tongue 26 returns to the locked state driven by the floating spring 30. In other words, even if the lock pin 19 is in the locked state, after the user manually closes the door body 1, the inclined top structure of the lock tongue 26 abuts against the door frame 20, which will push the lock tongue 26 close to the connection part 27, so that it passes over the door frame 20 and enters the lock hole 21. After fully entering the lock hole 21, the lock tongue 26 is fully extended to achieve the locking effect.

[0099] The rear end of the lock tongue 26 is provided with two first lock hooks 28 arranged side by side and facing outward, with a gap between the two lock hooks, and the front end of the connecting portion 27 is provided with second lock hooks 29 arranged side by side and facing inward, with the two first lock hooks located between the two second lock hooks. The first lock hook 28 and the second lock hook 29 restrict each other to prevent the lock tongue 26 from being separated from the connecting portion 27.

[0100] A guide rib 31 is disposed on the outer side of the first lock hook 28, and a matching guide groove is disposed on the inner side of the second lock hook 29. The guide rib 31 is slidably connected in the guide groove along the second direction to play a role of limiting and guiding.

[0101] like Fig.13 As shown, the disinfection cabinet control method provided by the present invention is applied to the above-mentioned disinfection cabinet, comprising:

[0102] Step S10. When the thermal cycle mechanism is started and the difference h between the temperature in the disinfection chamber 42 and the external environment temperature is greater than or equal to a first preset temperature difference, the baffle assembly is driven by the driving mechanism to switch from the first state to the second state.

[0103] The drying function of the disinfection cabinet is turned on, and the heating device 45 and the circulating fan 44 start working at the same time. At this time, under the action of the heat circulation mechanism, the hot air flow inside the disinfection cavity 42 presents an internal circulation form, and is sucked in by the circulating fan 44 at the upper part of the air duct cavity 43. After passing through the air duct cavity 43, it enters the disinfection cavity 42 from the air outlet channel below, and the air flow continues to flow toward the door body 1. At the same time, the heating device 45 in front of the air outlet channel heats the air flow, and due to the principle of hot air floating, it reaches the upper part of the disinfection cavity 42, and is then sucked in by the circulating fan 44 to complete the internal circulation process.

[0104] The temperature in the disinfection chamber gradually rises. When the temperature in the disinfection chamber is higher than the ambient temperature outside the cabinet by a first temperature difference value (for example, the first temperature difference value is 50°C), water vapor begins to appear in the disinfection chamber 42. The push rod motor 13 shrinks and moves downward, driving the first baffle 3 to tilt backward to the first position through the push rod. At this time, the first baffle 3 and the outer door panel 2 open a gap, but the gap is only used for water vapor to flow outward, which is not enough for the hand to be inserted. At this time, the hot air flow in the disinfection chamber 42 is converted into an external circulation. The air in the disinfection chamber 42 is sucked in by the circulation fan 44 on the upper part of the back plate, passes through the air duct cavity 43 outside the disinfection chamber 42, and then flows toward the door body 1 through the opening at the bottom of the back plate. At the same time, the heating device 45 in front of the opening at the bottom of the back plate heats the air flow. Due to the principle of hot air floating, it reaches the top of the cavity. At this time, the air temperature in the disinfection chamber 42 is high, forming a high pressure, and the hot air drives the water vapor to be discharged from the gap of the first baffle 3 to the outside.

[0105] Step S20: When the baffle assembly is in the second state, after the thermal cycle mechanism continues to operate for a first preset time, the drive mechanism drives the baffle assembly to switch from the second state to the first state.

[0106] After a first period of time (for example, the first preset time is 10 minutes), almost all of the water vapor in the disinfection chamber 42 is discharged; the push rod motor 13 moves upward, the first baffle 3 is closed, and the internal circulation hot air flow pattern in the disinfection chamber 42 is restored.

[0107] Step S30: When the drying task is completed, the baffle assembly is driven by the driving mechanism to switch from the first state to the third state.

[0108] Wait until the drying working time ends or the user actively turns off the drying function. The user can click the unlock function key. The push rod motor 13 automatically works, the push rod moves downward, and the push rod drives the first baffle 3 to tilt backward to the third position. At this time, the opening size is completely sufficient for the hand to reach in; pull the handle 6 to open the door body 1.

[0109] The disinfection cabinet control method provided by the present invention also includes the steps of:

[0110] When the baffle assembly is in the third state for a second preset time (for example, the second preset time is 1 minute) and no unlocking instruction is received, the driving mechanism drives the baffle assembly to switch to the first state to achieve automatic resetting.

[0111] The disinfection cabinet control method provided by the present invention also includes the steps of:

[0112] Detect whether the baffle assembly is obstructed during the state switching process;

[0113] When there is no obstruction, the driving mechanism switches the baffle assembly from the current state to the target state;

[0114] When obstructed, the driving mechanism switches the baffle assembly from a current state to a previous state.

[0115] If there is an obstacle during the closing process of the baffle assembly, when the push rod motor 13 senses resistance and returns to the previous state, it will wait for a period of time (for example, 10 seconds) and then re-detect and count the number of times by one. If the obstacle is cleared, the drive mechanism continues to execute the previous state switching instruction. If the obstacle is not cleared, it will wait for the first period of time (for example, 10 seconds) and then re-detect and count the number of times by one, until the number of times is greater than 3 times, the buzzer will warn for a period of time (for example, 15 seconds), and the machine will stop working and wait for the user to check.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
