Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable delivery technology, and more specifically, to a fruit and vegetable delivery box. Background Technology

[0002] Fruits and vegetables are an indispensable part of daily life. After harvesting, they are usually placed in delivery boxes for easy handling and delivery.

[0003] Currently, when using delivery boxes to pack fruits and vegetables, the boxes are usually opened, the fruits and vegetables are placed inside, and then the boxes are closed to achieve the effect of packing. However, fruits and vegetables are still living organisms after being picked, and they continue to respire and release ethylene gas. Ethylene is a potent plant ripening hormone, and the inside of the delivery boxes is relatively closed, which causes ethylene to accumulate inside the boxes, accelerating the ripening, softening, and aging process of the fruits and vegetables, and affecting their preservation effect.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a fruit and vegetable delivery box that solves the problem that ethylene released by fruits and vegetables will continuously accumulate inside the delivery box, accelerating the ripening, softening, and aging process of the fruits and vegetables and affecting their preservation effect.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fruit and vegetable delivery box, including a box body with a cover, an air outlet on one side of the box body, an exhaust fan installed at the air outlet, a power supply installed inside the box body, the power supply and the exhaust fan being electrically connected, a fixing plate fixedly connected inside the box body, a plurality of through holes on the fixing plate, an air inlet on one side of the box body located between the fixing plate and the bottom of the box body, and an adjustment component for adjusting the air inlet on the box body.

[0007] The present invention is further configured such that: the adjusting component includes a baffle slidably connected to the outer wall of the box, a slide rail for the baffle to slide is fixedly connected to the outer wall of the box, a rubber-made locking block is fixedly connected to one side of the baffle, and a slot is provided on one side wall of the slide rail that is arranged longitudinally and engages with the locking block.

[0008] The present invention is further configured such that a lever is fixedly connected to one side of the baffle.

[0009] The present invention is further configured such that: a number of horizontally arranged guide ribs are fixedly connected to the inner wall of the box between the fixed plate and the bottom of the box.

[0010] The present invention is further configured such that filters are fixedly connected to both the air inlet and the air outlet.

[0011] The present invention is further configured such that: a plurality of support frames are slidably connected to the fixed plate, a plurality of placement frames for placing fruits and vegetables are fixedly connected to the support frames, there is a gap between adjacent placement frames, a connecting plate is fixedly connected to one side of the support frame, a through groove for the connecting plate to slide is opened on one side of the box body, and a handle is fixedly connected to the side of the connecting plate away from the support frame.

[0012] The present invention is further configured such that: a second slide rail is fixedly connected to the fixed plate, and the support frame and the second slide rail are slidably connected.

[0013] In summary, this utility model has the following beneficial effects: 1. The exhaust fan blows the ethylene inside the box to the outside, while the air inlet draws outside air between the fixed plate and the bottom of the box, and exhausts it to the fruits and vegetables through the holes on the fixed plate, making up for the air lost inside the box. This cleans the ethylene inside the box, thereby slowing down the ripening, softening and aging process of the fruits and vegetables and improving the preservation effect.

[0014] 2. The through-hole design allows air to enter the chamber in a diffused manner, which buffers the incoming air, slows down the airflow, and prevents cold / hot dry air from directly impacting the fruits and vegetables, causing local frost damage or dehydration, thus further improving the preservation effect of fruits and vegetables.

[0015] 3. The size of the air inlet can be changed by adjusting the components, thereby changing the air volume at the air outlet, thus achieving stepless or graded adjustment of the ventilation volume at the air inlet and air outlet. Attached Figure Description

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" 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 an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] A type of fruit and vegetable delivery box, such as Figures 1-5 As shown, the box includes a box body 2 with a cover plate 1. An air outlet 3 is opened on one side of the box body 2, and an exhaust fan 4 is installed at the air outlet 3. A power supply 5 is installed inside the box body 2, and the power supply 5 and the exhaust fan 4 are electrically connected. A fixing plate 6 is fixedly connected inside the box body 2, and several through holes 7 are opened on the fixing plate 6. An air inlet 8 is opened on one side of the box body 2 between the fixing plate 6 and the bottom of the box body 2. An adjustment component is provided on the box body 2 for adjusting the air inlet 8. A filter screen 15 is fixedly connected to both the air inlet 8 and the air outlet 3 to prevent external dust from entering the box body 2. When filling fruits and vegetables, the box body 2 is opened, the fruits and vegetables are placed on the fixing plate 6, and the box body 2 is closed to achieve the effect of filling fruits and vegetables.

[0022] When the fruit releases ethylene, because ethylene is lighter than air, it floats above the box 2. At this time, the exhaust fan 4 is activated by the power supply 5, which blows the ethylene inside the box 2 to the outside. At the same time, outside air is drawn into the space between the fixed plate 6 and the bottom of the box 2 through the air inlet 8, and discharged to the fruits and vegetables through the through holes 7 on the fixed plate 6, making up for the air lost inside the box 2. This achieves the effect of cleaning the ethylene inside the box 2, thereby delaying the ripening, softening and aging process of the fruits and vegetables, and improving the preservation effect. In addition, the through holes 7 allow the air to enter the box 2 in a diffused manner, which has a buffering effect on the incoming air, slows down the air flow, and avoids cold / hot dry air directly impacting the fruits and vegetables, causing local frost damage or dehydration, further improving the preservation effect. At the same time, the size of the air inlet 8 can be changed by adjusting the components, thereby changing the air volume at the air outlet 3, so as to achieve stepless or graded adjustment of the ventilation volume at the air inlet 8 and the air outlet 3.

[0023] Furthermore, several support frames 16 are slidably connected to the fixed plate 6, and several placement frames 17 for placing fruits and vegetables are fixedly connected to the support frames 16. There is a gap between two adjacent placement frames 17. A connecting plate 18 is fixedly connected to one side of the support frame 16, and a through groove 19 for the connecting plate 18 to slide is opened on one side of the box body 2. A handle 20 is fixedly connected to the side of the connecting plate 18 away from the support frame 16. A second slide rail 21 is fixedly connected to the fixed plate 6. The slidable connection between the support frame 16 and the second slide rail 21 can improve the stability of the support frame 16 on the fixed plate 6 and facilitate the movement of the support frame 16.

[0024] When it is necessary to place fruits and vegetables into the box 2, the support frame 16 is pulled by the handle 20, which drives the support frame 16 to move along the slide rail 21 and pulls the support frame 16 together with the placement frame 17 outward from the through groove 19. Then, the fruits and vegetables are placed in the placement frame 17, and finally the support frame 16 is pushed back to its original position, thus completing the effect of placing fruits and vegetables into the box 2. The spacing between adjacent placement frames 17 facilitates the treatment of ethylene released by the fruits and vegetables at the bottom of the box 2, and avoids its accumulation inside the fruits and vegetables.

[0025] like Figures 1-3 As shown, the adjustment assembly includes a baffle 9 slidably connected to the outer wall of the housing 2. A slide rail 10 for sliding the baffle 9 is fixedly connected to the outer wall of the housing 2. A locking block 11 is fixedly connected to one side of the baffle 9. The locking block 11 is made of rubber and has the ability to deform. The side wall of the slide rail 10 has slots 12 arranged longitudinally and engaging with the locking block 11. A lever 13 is fixedly connected to one side of the baffle 9, which facilitates driving the baffle 9 to move along the side wall of the slide rail 10.

[0026] When adjusting the size of the air inlet 8, a pulling force is applied to the baffle 9, causing the baffle 9 to move downward along the slide rail 10. At this time, the distance between the baffle 9 and the bottom of the air inlet 8 is shortened, thereby reducing the amount of air entering the housing 2 through the air inlet 8. When the baffle 9 moves upward, the distance between the baffle 9 and the bottom of the air inlet 8 is extended, thereby increasing the amount of air entering the housing 2 through the air inlet 8. This achieves the effect of adjusting the size of the air inlet 8.

[0027] Furthermore, a number of horizontally arranged guide ribs 14 are fixedly connected to the inner wall of the box 2 between the fixed plate 6 and the bottom of the box 2. When air enters between the fixed plate 6 and the bottom of the box 2 through the air inlet 8, the guide ribs 14 can guide the air to be transported to the inner wall of the box 2, so that the air entering the box 2 is more uniform.

[0028] The usage process of this utility model is as follows: When filling the boxes with fruits and vegetables, open the box 2, place the fruits and vegetables on the fixed plate 6, and close the box 2 to achieve the effect of filling the fruits and vegetables.

[0029] When the fruit releases ethylene, because ethylene is lighter than air, it floats above the container 2. At this time, the exhaust fan 4 is activated by the power supply 5, blowing the ethylene from inside the container 2 to the outside. Simultaneously, outside air is drawn into the space between the fixing plate 6 and the bottom of the container 2 through the air inlet 8, and discharged towards the fruits and vegetables through the through-holes 7 on the fixing plate 6, replenishing the air lost inside the container 2. This effectively removes the ethylene from the container 2, thus slowing down the ripening, softening, and aging process of the fruits and vegetables, improving their preservation. Furthermore, the through-holes 7 allow air to diffuse into the container 2, buffering the incoming air and slowing its flow, preventing... Cold / hot dry air directly impacts fruits and vegetables, causing localized frost damage or water loss, further improving the preservation effect. At the same time, when adjusting the size of the air inlet 8, a pulling force is applied to the baffle 9, driving the baffle 9 to move downward along the slide rail 10. At this time, the distance between the baffle 9 and the bottom of the air inlet 8 is shortened, thereby reducing the amount of air entering the box 2 through the air inlet 8. When the baffle 9 moves upward, the distance between the baffle 9 and the bottom of the air inlet 8 is extended, thereby increasing the amount of air entering the box 2 through the air inlet 8. This achieves the effect of adjusting the size of the air inlet 8, thereby changing the air volume at the air outlet 3, thus realizing stepless or graded adjustment of the ventilation volume at the air inlet 8 and the air outlet 3.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
