DETAILED DESCRIPTION Embodiment 1

[0031] See also Figures 1 to 3 The embodiment of the present invention provides a fruit and vegetable fresh air system, which is mainly used to ensure the freshness of fruits during transportation and carrying. The fruit and vegetable fresh air system includes a cover plate 1 and a box body 8 rotatably connected to the cover plate 1. The cover plate 1 and the box body 8 are placed vertically. Figure 1 For example, the cover plate 1 is located at the front side of the box body 8; and in this embodiment, the lower side of the cover plate 1 is rotatably connected to the lower side of the box body 8.

[0032] A placement cavity 101 is provided in the middle of the rear side of the cover plate 1 (i.e., the side close to the box body 8), and a rotating component 2 for cooling and preserving the products in the box body 8 is arranged inside the placement cavity 101. An air inlet 102 connected with the placement cavity 101 and used to provide air to the rotating component 2 is provided at the upper rear side of the cover plate 1. An auxiliary component 4 connected with the placement cavity 101 and used to further cool and preserve the products in the box body 8 is provided at the lower rear side of the cover plate 1. A moving component 3 is provided inside the placement cavity 101, which is transmission-connected with the rotating component 2 and is used to drive the auxiliary component 4 to move and thus form a positive correspondence with the rotating component 2.

[0033] When the rotating component 2 is started, the product in the box body 8 is immediately cooled by blowing air through the placement cavity 101, and the rotating component 2 also drives the auxiliary component 4 to move through the moving component 3 to form a positive correspondence with the rotating component 2. At this time, the rotating component 2 acts on the auxiliary component 4 to finally generate water mist, which can further cool the product by water mist.

[0034] In this embodiment, the interior of the box body 8 can be used to store a certain amount of fruit. Of course, the interior of the box body 8 can also be used to place other vegetable products, or the box body 8 and the cover 1 can be directly applied to the existing logistics carriage, that is, this solution has a variety of application scenarios.

[0035] See also Figures 1 to 5 In this embodiment, preferably: the rotating assembly 2 includes a support rod 201 rotatably connected to the cavity wall of the placement cavity 101 and a control member (not shown in the figure) for driving the support rod 201 to rotate. A plurality of blades 202 are fixedly installed on the outer surface of the support rod 201. When the control member is activated, the support rod 201 can drive the plurality of blades 202 to rotate to form a blowing. The outer surface of the support rod 201 is also rotatably mounted with a gear 203 that is transmission-connected to the moving assembly 3 through a one-way bearing. The one-way bearing limits the support rod 201 to drive the gear 203 to rotate in one direction, and the gear 203 can rotate in another direction by itself, and the support rod 201 will not rotate when the gear 203 rotates in another direction.

[0036] In the above structure, if Figure 3 As shown, since the moving component 3 will drive the auxiliary component 4 to move to the corresponding position with the fan blade 202 to form wind and further form water mist, the gear 203 is arranged on the side of the fan blade 202 away from the box body 8, so as to avoid the gear 203 blocking the auxiliary component 4, so that the wind blown by the fan blade 202 can be completely directed to the auxiliary component 4.

[0037] Furthermore, the auxiliary component 4 includes a water tank 401 provided at the lower rear side of the cover plate 1, and a sponge 402 is slidably provided inside the water tank 401 and moves synchronously with the moving component 3. A water source is provided inside the water tank 401 and the sponge 402 is immersed in the water source, so that the sponge 402 can be moistened and then, in a state corresponding to the fan blades 202, water mist can be formed by the rotation and blowing of the fan blades 202. Among them, the sponge 402 can form a vertical rise and fall along the water tank 401 under the action of the moving component 3, can be moistened and replenished when descending, and can form water mist to cool down when ascending. In order to ensure the stable production of water mist, a hole plate (not shown in the figure) for atomization can also be fixedly installed on the surface of the placement cavity 101 close to the box body 8, and the hole diameter of the hole plate is small so that water droplets form water mist when passing through the hole plate.

[0038] Because the cover plate 1 and the box body 8 are placed in a vertical state, the water tank 401 and the sponge 402 are both located below the fan blades 202. The water source in the water tank 401 will not automatically overflow during transportation and carrying, and the water source accumulated in the sponge 402 after rising will not drip directly onto the product in the box body 8, but will automatically fall due to gravity and fall back into the water tank 401, which can ensure the effective use of water. At the same time, a water inlet hole (not shown in the figure) connected to the water tank 401 can also be opened on the cover plate 1, and a one-way valve can be installed in the water inlet hole, so that water can be added to the water tank 401 through the one-way valve and the water inlet hole, and the water source in the water tank 401 will not flow out from the water inlet hole; the one-way valve is an existing mature technology and will not be described in detail here.

[0039] Further, the moving assembly 3 includes a tooth plate 301 that is slidably matched with the placement cavity 101 and is transmission-connected with the gear 203. A first spring 303 is fixedly installed between the end of the tooth plate 301 away from the auxiliary assembly 4 and the hole wall of the air inlet 102. Under the action of the first spring 303, the tooth plate 301 has a tendency to move toward the auxiliary assembly 4. A connecting piece 302 for driving the sponge 402 to move is fixedly installed on the surface of the tooth plate 301. When the tooth plate 301 rises under the action of the gear 203, the sponge 402 can be driven to rise synchronously through the connecting piece 302. When the tooth plate 301 descends under the action of the first spring 303, the sponge 402 can be driven to descend synchronously through the connecting piece 302. The setting of the air inlet 102 can facilitate the rotation of the fan blade 202 to inhale air from the outside, and can also provide space for the lifting and lowering movement of the tooth plate 301, and can also provide a support point for the setting of the first spring 303.

[0040] In the above structure, an air outlet hole (not shown in the figure) can be opened through the surface of the cover plate 1, and the original gas in the box body 8 can be discharged through the air outlet hole when the fan blade 202 rotates to blow air. Of course, the air outlet hole can also be opened on the box body 8. Because the box body 8 and the cover plate 1 are in a vertical position in this solution, the air inlet hole 102 is opened on the upper side for air intake, so the air outlet hole can also be opened on the upper side of the box body 8 to facilitate the discharge of the original gas in the box body 8, which is carbon dioxide and ethylene generated by the product in the box body 8 during transportation and storage.

[0041] In this embodiment, Figure 5 As shown, when the air inlet 102 is located on the upper side of the cover plate 1, a switch 5 electrically connected to the control element can be installed on the upper side of the cover plate 1, and a battery 6 electrically connected to the switch 5 and a control module 7 electrically connected to the switch 5 are fixedly installed inside the cover plate 1. The switch 5 can be started and closed at a fixed time through the control module 7, thereby realizing the control element driving the support rod 201 to start and stop at a fixed time. Among them, the switch 5, the battery 6 and the control module 7 are all existing mature technologies and are not described in detail here.

[0042] When in use, the product is placed in the box body 8 and closed by the cover plate 1. The box body 8 and the cover plate 1 are as shown in FIG. Figure 1The product in the box body 8 is placed in a state and kept in this state for transportation and carrying. In this process, the start control member drives the support rod 201 to rotate, and the support rod 201 drives the fan blade 202 to rotate to suck air through the air inlet 102 to directly blow air to cool the product in the box body 8. When the fan blade 202 rotates and blows air, it can also make the original gas in the box body 8 be discharged from the air outlet. The support rod 201 drives the tooth plate 301 to rise and squeeze the first spring 303 through the gear 203. Under the action of the first spring 303, the tooth plate 301 can maintain the meshing state with the gear 203. When the tooth plate 301 rises, it drives the sponge 402 to rise and move out of the water tank 401 through the connecting member 302, and moves to a state that is directly corresponding to the fan blade 202. At this time, the blowing of the fan blade 202 acts on the water-containing sponge 402 to finally form water mist, which escapes into the box body 8 through the placement cavity 101 to effectively cool the product. When the support rod 201 and the fan blade 202 stop rotating, the tooth plate 301 is reset under the action of the first spring 303, and the tooth plate 301 drives the sponge 402 to be retracted into the water tank 401 through the connecting piece 302 to absorb water, so as to prepare for the next removal to generate water mist, and the gear 203 can rotate based on the support rod 201 under the action of the one-way bearing.

[0043] In summary, through the coordination of the gear 203, the tooth plate 301, the air inlet 102 and the sponge 402, it is possible to achieve primary cooling of the product by blowing air, and to form water mist for further cooling, and quickly discharge the carbon dioxide and ethylene generated in the box body 8, which has excellent effects in the transportation and carrying of products in hot weather such as summer. The overall structure is compact, and the components are combined with the cover plate 1 of the box body 8, so that the water source in the water tank 401 will not flow out during transportation and carrying, and the water source can be effectively utilized; and the overall structure is formed into a gift box (fruit gift box, vegetable gift box), which has a good application prospect in the transportation and carrying of high-end products and high-value products, and is more satisfactory and more practical in daily communication and gift-giving. Embodiment 2

[0044] See also Figures 1 to 8On the basis of the first embodiment, in order to further facilitate the overall transportation and carrying, the connecting member 302 includes an arc plate 3022 for closing the notch of the water tank 401 and a guide rod 3024 that is rotatably matched with the cover plate 1, and two pull ropes 3021 are fixedly wound on the outer surface of the guide rod 3024, and the movable ends of the two pull ropes 3021 are respectively fixedly connected to the tooth plate 301 and the arc plate 3022. The two pull ropes 3021 are wound in opposite directions on the guide rod 3024, and a coil spring (not shown in the figure) is also sleeved on the outer surface of the guide rod 3024, so that when the tooth plate 301 rises, the coil spring acts on the guide rod 3024 to reel in the corresponding pull rope 3021, and the other pull rope 3021 is also in a reeling state, so that the arc plate 3022 also starts to rise, and finally the tooth plate 301 and the arc plate 3022 form a synchronous movement.

[0045] Among them, a short rod 3023 for driving the sponge 402 to move is fixedly installed at the bottom of the arc plate 3022. When the arc plate 3022 rises, the sponge 402 can be driven to move synchronously from the water tank 401 through the short rod 3023. When the arc plate 3022 descends, the sponge 402 can be driven to descend back into the water tank 401 through the short rod 3023. At the same time, the arc plate 3022 can close the notch of the water tank 401 to prevent the water source in the water tank 401 from flowing out. On this basis, as long as the notch of the water tank 401 is not placed downward (that is, as long as the air inlet 102 is not placed downward), the water source in the water tank 401 will not flow out. In this state, the box body 8 and the cover plate 1 can still be placed in a vertical state.

[0046] See also Figures 1 to 8 In this embodiment, preferably: the tooth plate 301 can be designed to be flexible and a groove 104 is provided inside the cover plate 1 for the flexible tooth plate 301 to be placed. At this time, the tooth plate 301 and the water tank 401 are no longer in contact, which can ensure the sealing of the water tank 401 and prevent water from leaking out. In order to guide the flexible tooth plate 301, a guide rail 103 is fixedly installed inside the placement cavity 101. The guide rail 103 is designed to be arc-shaped and its edge is designed to be collinear with the hole wall of the air inlet hole 102, so that the flexible tooth plate 301 can enter the hole wall of the air inlet hole 102 under the guidance of the guide rail 103 and maintain a vertical rising state, and in the process of descending, it first descends vertically along the hole wall of the air inlet hole 102, and returns to the groove 104 under the action of the guide rail 103.

[0047] If the tooth plate 301 does not adopt a flexible design, the front and rear positions of the tooth plate 301 can also be adjusted so that the tooth plate 301 and the water tank 401 are staggered to ensure that the water source in the water tank 401 does not flow out.

[0048] Furthermore, the wall of the water tank 401 close to the box body 8 is inclined. Figure 8The first bevel 4011 in the water tank 401, the upper end of the first bevel 4011 is farther away from the box body 8 than the lower end thereof, so that the water tank 401 is in the shape of a right-angled trapezoid as a whole. When placed in a vertical state, the water source can be located at the bottom of the water tank 401. When the cover plate 1 and the box body 8 are placed in a horizontal state, the water source can be contained by the first bevel 4011 of the water tank 401, and the phenomenon of water source flowing out of the notch of the water tank 401 will not occur.

[0049] Among them, the upper end of the first bevel 4011 cooperates to form the notch part of the water trough 401. On this basis, the notch size of the water trough 401 can be set to be smaller than the size of the sponge 402, so that the sponge 402 needs to be squeezed when passing through the notch of the water trough 401 before it can be moved out. A part of the accumulated water in the sponge 402 can be pressed out to avoid excessive water absorption in the sponge 402. When it is moved to the placement cavity 101, it directly flows down and falls on the product in the box body 8. The above design is effective when the box body 8 and the cover plate 1 are placed in a horizontal state.

[0050] When in use, the product is placed in the box body 8 and closed by the cover plate 1. The air blowing cooling and water mist cooling of the product in the box body 8 are achieved through the cooperation of the gear 203 and the tooth plate 301. The working process and effect of this part are the same as those in the first embodiment, and are not repeated here. The difference is that when the gear 203 rotates to drive the rack to rise, the rack makes the corresponding pull rope 3021 rise and then the guide rod 3024 rotates under the action of the coil spring. The coil spring makes another pull rope 3021 reel up and then the arc plate 3022, the short rod 3023 and the sponge 402 rise synchronously. When the sponge 402 rises to correspond to the fan blade 202, the air blowing cooling process is converted into the water mist cooling process.

[0051] The above process prevents water from flowing out of the water tank 401 regardless of whether the box body 8 and the cover plate 1 are placed in a vertical state or a horizontal state, and the sponge 402 will be squeezed when it moves out through the notch of the water tank 401, so as to prevent the sponge 402 from moving out when it contains more water and causing water droplets to drip freely. After the tooth plate 301 is reset under the action of the first spring 303, the curved plate 3022, the short rod 3023 and the sponge 402 can be automatically reset by the pull rope 3021, so that the curved plate 3022 closes the notch of the water tank 401. At this time, no matter how the box body 8 and the cover plate 1 are placed, the water will not flow out, which further facilitates the transportation, placement and carrying of the box body 8.

[0052] In the first embodiment, air blowing cooling and water mist cooling of the product in the box body 8 can be achieved, but there are high requirements for the placement state of the box body 8 and the cover plate 1. If the box body 8 is placed in a horizontal state, the water source in the water tank 401 will flow out and affect the quality of the product. At the same time, it will also soak the box body 8 and affect the service life of the box body 8. There are certain limitations in use.

[0053] Compared with the first embodiment, through the coordination of the gear 203, the pull rope 3021, the curved plate 3022 and the short rod 3023 and other structures, the water tank 401 can be effectively closed when the fan blade 202 is closed, so that the placement scenes of the box body 8 and the cover plate 1 are diversified, and the water source in the water tank 401 can be prevented from flowing out, thereby ensuring the quality of the product and the service life of the box body 8. When the fan blade 202 rotates, the blowing cooling and water mist cooling of the product can be guaranteed, and the sponge 402 can be squeezed to avoid excessive water from being removed and dripping onto the product. The squeezed water can also flow back to the water tank 401, thereby achieving effective utilization of the water source, so that the rotation of the fan blade 202 can be carried out when the box body 8 is placed horizontally or vertically. On this basis, it can also facilitate the rapid placement of the product in the box body 8, which has a multiple-purpose effect. The overall design is combined with the setting of the water tank 401 and the movement of the tooth plate 301, and the functionality and applicability are stronger. Embodiment 3

[0054] See also Figures 1 to 10 On the basis of the second embodiment, in order to achieve more effective use of the water source in the water tank 401, the wall of the water tank 401 away from the box body 8 is composed of a vertical side 4012 and a second oblique side 4013, the second oblique side 4013 and the first oblique side 4011 have the same inclination direction, and the length of the second oblique side 4013 is less than the first oblique side 4011, so that the short rod 3023 can smoothly descend. That is, the vertical side 4012 allows the short rod 3023 to drive the sponge 402 to descend vertically smoothly, and the second oblique side 4013 is used to form contact with the sponge 402.

[0055] On this basis, the sponge body 402 is composed of a first sponge layer 4021 that rotates with the short rod 3023 and a second sponge layer 4022 that slides with the first sponge layer 4021. The second sponge layer 4022 can slide back and forth along the first sponge layer 4021. A seal 4023 is fixedly installed on the top of the second sponge layer 4022, and a support rod 4024 is installed on the top of the seal 4023 and the outer surface of the short rod 3023 to rotate together. When the short rod 3023 drives the first sponge layer 4021 and the second sponge layer 4022 to descend and the first sponge layer 4021 contacts the second oblique edge 4013, the first sponge layer 4021 can rotate based on the short rod 3023 under the action of the second oblique edge 4013, and the first sponge layer 4021 can drive the second sponge layer 4022 to deflect synchronously. Under the action of the seal 4023 and the support rod 4024, the second sponge layer 4022 will also slide downward along the first sponge layer 4021 when deflecting.

[0056] See also Figures 1 to 10In this embodiment, preferably: in order to ensure that the first sponge layer 4021 and the second sponge layer 4022 are in a vertical state with the short rod 3023 in a normal state, a torsion spring (not shown in the figure) can be installed at the rotation point of the first sponge layer 4021 and the short rod 3023, and when the first sponge layer 4021 is subsequently separated from the second hypotenuse 4013, the first sponge layer 4021 and the second sponge layer 4022 can automatically reset and restore to a parallel vertical state.

[0057] When in use, the products can be quickly placed in the box body 8 in various placement states, and the products can be cooled by blowing and mist through the gear 203 and the gear plate 301. The working process and effect of this part are the same as those in the second embodiment, and will not be repeated here. The difference is that when the arc plate 3022 drives the first sponge layer 4021 and the second sponge layer 4022 to descend through the short rod 3023, if the first sponge layer 4021 contacts the second bevel 4013, the first sponge layer 4021 will drive the second sponge layer 4022 to deflect based on the short rod 3023 under the action of the second bevel 4013, and the second sponge layer 4022 will eventually slide down along the first sponge layer 4021 under the action of the seal 4023, the short rod 3023 and the support rod 4024, and the first sponge layer 4021 and the second sponge layer 4022 continue to descend, and finally the second sponge layer 4022 will contact the water source within the angle of the first bevel 4011, and absorb the water source within the angle. When the arc plate 3022 drives the first sponge layer 4021 and the second sponge layer 4022 to rise through the short rod 3023, if the first sponge layer 4021 is separated from the second bevel 4013, the first sponge layer 4021 and the second sponge layer 4022 can automatically reset to ensure the water mist cooling of the subsequent fan blades 202.

[0058] In the second embodiment, various placement requirements of the box body 8 and the cover plate 1 can be met on the basis of ensuring air blowing cooling and water mist cooling of the product. However, the water source in the first bevel 4011 cannot be fully utilized, and the water source accumulated in the angle of the first bevel 4011 cannot form contact with the sponge 402, which causes this part of the water source to always exist, which may cause bacteria to grow and affect product quality, and there are certain limitations in use.

[0059] Compared with the second embodiment, the coordination of the short rod 3023, the support rod 4024, the first sponge layer 4021 and the second sponge layer 4022 can achieve complete absorption of the water source at the angle of the first bevel 4011, avoiding the growth of bacteria caused by long-term accumulation of the water source, thereby achieving more efficient use of the water source and ensuring the quality of the product in the box body 8. The overall solution is combined with the design of the water tank 401, which will not affect the water mist cooling coordinated with the fan blades 202, and meets more needs in actual use.
