Description

Technical Field

[0001] This invention belongs to the technical field of self-pickup lockers, and in particular relates to a multi-temperature zone fresh food self-pickup locker and its temperature control method. Background Technology

[0002] Fresh produce refers to primary products sold without cooking, preparation, or other deep processing, requiring only necessary preservation and simple arrangement before being put on shelves. It also includes bread, cooked food, and other freshly processed goods. Fresh produce shares similar characteristics and storage conditions, requiring preservation, refrigeration, or freezing. With advancements in technology and the development of the internet, people often purchase fresh produce online and have it delivered by courier. This creates a time lag, preventing the fresh produce from being properly preserved, refrigerated, or frozen. Therefore, self-service fresh produce lockers are needed. Couriers place fresh produce inside these lockers to ensure it remains fresh, refrigerated, or frozen for a period of time while the customer is picking it up.

[0003] Existing publicly available documents disclose CN108711235A - a cabinet for self-pickup of fresh produce and a fresh produce self-pickup cabinet. The cabinet for self-pickup of fresh produce includes a cabinet body, which forms multiple storage spaces. The cabinet body also has an installation groove, on which a central control panel is installed. The central control panel has a central control cover. Each storage space has a cabinet opening, and the cabinet opening has a door. The cabinet opening is installed on the cabinet body, and a water guide groove is provided on the upper edge of the cabinet opening. The door has a first door seal that mates with the surface of the cabinet opening, and a second door seal that mates with the edge of the cabinet opening. The top of the central control panel has a first water-blocking end cap and a second water-blocking end cap. The first water-blocking end cap is fixed to the cabinet body and located above the outside of the installation groove. The second water-blocking end cap covers the top of the installation groove and wraps around the top of the central control panel. A drainage groove is formed on the upper surface of the second water-blocking end cap. While improving the waterproof performance of fresh food self-pickup lockers can enhance the user experience, it still has the following drawbacks in actual use:

[0004] 1. In order to increase the storage capacity, existing self-service lockers greatly reduce the volume of the locker compartments. This results in the locker compartments having too narrow retrieval openings, making it difficult for people to quickly and easily retrieve fresh produce from the locker.

[0005] 2. The existing self-service lockers are too large, and they cannot be easily moved regardless of whether they are placed horizontally or vertically.

[0006] 3. Existing self-service lockers cannot quickly reset after being pushed out, which makes it difficult to close them.

[0007] Therefore, existing multi-temperature zone fresh food self-pickup lockers and their temperature control methods cannot meet the needs of actual use, so there is an urgent need for improved technologies on the market to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a multi-temperature zone fresh food self-pickup locker and its temperature control method. By de-energizing the electromagnetic ring iron, the locker is automatically pushed out of the cabinet by the push plate, improving the self-pickup efficiency of personnel. The disassembly of the progressive assembly rod and the assembly column enables disassembly and movement, improving the movement efficiency. At the same time, the push of the return spring on the locker achieves automatic reset of the locker, facilitating the closing of the self-pickup locker.

[0009] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0010] This invention relates to a multi-temperature zone fresh food self-pickup cabinet, comprising a cabinet body, a sealing ring plate in the middle of the cabinet body, a refrigeration unit fixed at each of the four corners of the sealing ring plate, a partition ring plate attached to the inner side of the sealing ring plate, a square opening in the middle of the outer side wall of the partition ring plate, and multiple square openings evenly distributed in a ring along the side of the partition ring plate, each square opening having a storage cabinet inside, and a push hole corresponding to the position of the square opening on the inner side of the partition ring plate.

[0011] The square opening has movable square openings on both sides. Movable strips are fixed on both sides of the storage cabinet near the inner side of the partition ring plate, and the movable strips are placed in the corresponding movable square openings. Return springs are fixed on the side walls of the movable strips near the outer side of the partition ring plate, and the return springs are in contact with the side walls of the corresponding movable square openings.

[0012] A connecting block is provided in the middle of the inner side of the partition ring plate. A movable cylinder is fixed at the position of the push hole on the surface of the connecting block. An electromagnetic ring iron is fixed on the side wall of the connecting block on the surface of the movable cylinder. An automatic push plate is provided on the end face of the movable cylinder near the inner side of the partition ring plate. A push spring is fixed between the automatic push plate and the side wall of the connecting block.

[0013] Each of the automatic push plates has an adjusting rod fixed on its side wall near the connecting round block, and the adjusting rod is placed in the corresponding movable cylinder. Each adjusting rod has a metal ring on its surface near the connecting round block, and an adjusting arc block is fixed between the metal ring and the adjusting rod.

[0014] Assembly columns are fixed at the four corners of the left side of the cabinet exterior. Each of the four columns has a through hole at the position corresponding to the middle of the left side wall of the cabinet exterior. Assembly holes are opened at the positions of the four columns on the right side wall of the cabinet exterior. Each of the four holes has a push hole at the position corresponding to the middle of the right side wall of the cabinet exterior. Each push hole has a progressive assembly rod inside it.

[0015] The cabinet has through holes at the corresponding push holes on the right side wall, and a secondary control motor is fixed inside each through hole. The progressive assembly rod has a progressive rack plate fixed near the through hole on its outer side wall. The shaft end of the secondary control motor has a progressive gear, which meshes with the corresponding progressive rack plate.

[0016] Furthermore, a self-lifting opening is provided in the middle of the front side wall of the cabinet, and an intelligent cabinet door is installed inside the self-lifting opening. A main control panel is fixed on the front side wall of the cabinet directly above the self-lifting opening.

[0017] Furthermore, a storage opening is provided on the side wall of the sealing ring plate at the position corresponding to the self-lifting opening, a touch switch is fixed on the left side wall of the sealing ring plate near the storage opening, and an infrared receiver is fixed on the right side wall of the sealing ring plate near the storage opening.

[0018] Furthermore, each of the left side walls of the partition ring plate has a placement opening at the position corresponding to the square opening, and an electric plate is fixed inside each placement opening. The electric plate is ferroelectrically connected to the corresponding electromagnetic ring. Each of the right side walls of the partition ring plate has an information sensor fixed at the position corresponding to the square opening.

[0019] Furthermore, each movable strip has a movable hole on its side wall corresponding to the position of the reset spring, and each movable square opening has a movable rod fixed on its inner side corresponding to the position of the movable hole. The movable strip is slidably sleeved on the corresponding movable rod through the movable hole, and each reset spring is slidably sleeved on the corresponding movable rod.

[0020] Furthermore, the movable cylinder has adjustment openings on its outer sidewall corresponding to the position of the adjustment arc block, the adjustment arc block passes through the corresponding adjustment opening, and the metal ring is sleeved on the corresponding movable cylinder outer sidewall.

[0021] Furthermore, mounting ring frames are provided on the inner sides of the sealing ring plates on the left and right sides of the connecting round block, and the mounting ring frames are fixedly connected to the connecting round block and the sealing ring plates respectively. The left and right side walls inside the cabinet are provided with mounting openings, and the main control motor is fixed inside each mounting opening, and the shaft end of the main control motor is fixedly connected to the corresponding mounting ring frame.

[0022] Furthermore, a buffer pad is fixed to the inner wall of the sealing ring plate at the position corresponding to the partition ring plate, and a foam pad is fixed to the inner side of the storage cabinet.

[0023] This invention also provides a temperature control method for multi-temperature zone fresh food self-pickup lockers:

[0024] The entire self-service locker is connected to an external power source and network. Since the internal cooler is connected to the main control panel, when adjusting the temperature inside the locker, an external administrator needs to obtain operating access to the main control panel. At this time, the administrator can operate the main control panel to control the cooler and regulate the temperature inside the locker.

[0025] The present invention has the following beneficial effects:

[0026] 1. This invention incorporates an electromagnetic ring and an automatic push plate. When the energized plate on the side wall of the separating ring plate is in prolonged contact with the direct touch switch, the power supply on the energized plate is de-energized, causing the electromagnetic ring to stop attracting the metal ring. Consequently, the push spring pushes the automatic push plate, which then pushes the locker out of the cabinet from the storage opening and self-service opening, placing the locker outside the cabinet for easy and quick retrieval by users, thus improving their retrieval efficiency.

[0027] 2. This invention, by setting up assembly columns and progressive assembly rods, allows for the disassembly and individual movement of multiple cabinets when necessary. The main control panel operates the corresponding secondary control motor in reverse, causing the secondary control motor to drive the progressive gear plate to move into the push hole. This, in turn, moves the progressive assembly rod into the push hole, preventing the assembly columns from being confined within the assembly hole. This allows for the disassembly of individual cabinets, facilitating their movement and improving worker efficiency.

[0028] 3. This invention, by setting up a movable strip and a return spring, allows the storage cabinet to automatically reset after the push plate is reset. At this time, the storage cabinet is no longer pushed, so the movable strip on the storage cabinet no longer squeezes the return spring. Consequently, the return spring will move the movable strip towards the inside of the partition ring plate, which will then drive the storage cabinet to move into the square opening, thereby achieving the function of automatic reset of the storage cabinet. This facilitates the closing of the smart cabinet door and improves the closing efficiency. Attached Figure Description

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0047] Please see Figure 1-14As shown, this invention is a multi-temperature zone fresh food self-pickup cabinet, including a cabinet body 1. A sealing ring plate 2 is provided in the middle of the interior of the cabinet body 1. Refrigerators 201 are fixed at the four corners of the sealing ring plate 2. A partition ring plate 5 is attached to the inner side of the sealing ring plate 2. A square opening 503 is opened in the middle of the outer side wall of the partition ring plate 5, and multiple square openings 503 are evenly distributed in a ring along the side of the partition ring plate 5. A storage cabinet 6 is provided inside each square opening 503. Push holes 504 are provided at the positions corresponding to the square openings 503. When the automatic push plate 8 is in the corresponding storage cabinet 6, the automatic push plate 8 will pass through the inside of the push holes 504. Movable square openings 505 are provided on both sides of the square opening 503. Movable strips 601 are fixed on both sides of the storage cabinet 6 near the inner side of the partition ring plate 5, and the movable strips 601 are placed in the corresponding movable square openings 505. The side walls of the movable strips 601 near the outer side of the partition ring plate 5 are also provided with... A return spring 603 is fixed. When the locker 6 moves out of the square opening 503, the locker 6 will drive the movable strip 601 to move inside the movable square opening 505. The movable strip 601 will squeeze the return spring 603, and the return spring 603 will be in contact with the side wall of the corresponding movable square opening 505. When the automatic push plate 8 pushes the locker 6 out of the cabinet 1 from the storage opening 203 and the self-lifting opening 105 in sequence from inside the square opening 503, the person retrieving the items can take out the fresh food inside the locker 6. At the same time, after the automatic push plate 8 resets, the locker 6 is no longer pushed. Therefore, the movable strip 601 on the locker 6 no longer squeezes the return spring 603. Then the return spring 603 will move the movable strip 601 towards the inside of the partition ring plate 5, which will drive the locker 6 to move into the square opening 503, thereby achieving automatic reset. At the same time, the smart cabinet door 102 can be closed.

[0048] A connecting block 3 is provided in the middle of the inner side of the partition ring plate 5. A movable cylinder 301 is fixed at the position corresponding to the push hole 504 on the surface of the connecting block 3. An electromagnetic ring iron 302 is fixed on the side wall of the connecting block 3 on the surface of the movable cylinder 301. An automatic push plate 8 is provided on the end face of the movable cylinder 301 near the inner side of the partition ring plate 5. A push spring 801 is fixed between the automatic push plate 8 and the side wall of the connecting block 3. An adjusting rod 803 is fixed on the side wall of the automatic push plate 8 near the connecting block 3, and the adjusting rod 803 is placed inside the corresponding movable cylinder 301. A metal ring 802 is provided on the surface of the adjusting rod 803 near the connecting block 3, and the metal ring 802 is positioned close to the adjusting rod 803. Each of the cabinets is fixed with an adjustment arc block 804. A touch switch 202 is fixed on the left side wall of the sealing ring plate 2 near the storage opening 203. An infrared receiver 204 is fixed on the right side wall of the sealing ring plate 2 near the storage opening 203. A placement opening 507 is opened on the left side wall of the partition ring plate 5 at the position corresponding to the square opening 503. An electric board 501 is fixed inside the placement opening 507. The electric board 501 is electrically connected to the corresponding electromagnetic ring iron 302. An information sensor 502 is fixed on the right side wall of the partition ring plate 5 at the position corresponding to the square opening 503. An installation opening 108 is opened on the left and right side walls inside the cabinet 1. A main control motor 4 is fixed inside the installation opening 108.

[0049] With the above-described structure, when the courier is storing fresh produce, they scan the payment code on the main control panel 101 and operate the main control panel 101 to control the main control motor 4. The main control motor 4, through the mounting ring frame 7, drives the partition ring plate 5 and the connecting block 3 to rotate and move. Therefore, the partition ring plate 5 causes the information sensors 502 on the partition ring plate 5 to contact the infrared receivers 204 one by one. The information sensors 502 determine the state inside the corresponding locker 6. When the information sensor 502 determines that the locker 6 is empty, it transmits information to the main control panel 101 to control the operation. The main control motor 4 stops working and controls the smart cabinet door 102 to open. At this time, the energized plate 501 on the side wall of the partition ring plate 5 is in contact with the direct touch switch 202 for a long time, and the power supply on the energized plate 501 is cut off. As a result, the electromagnetic ring iron 302 no longer attracts the metal ring 802. Therefore, the push spring 801 pushes the automatic push plate 8, so that the automatic push plate 8 directly pushes the storage cabinet 6 from the inside of the square opening 503 through the storage opening 203 and the self-pickup opening 105 to the outside of the cabinet body 1. This makes the storage cabinet 6 outside the cabinet body 1, so that the self-pickup personnel can quickly retrieve their items.

[0050] After the courier pays, the locker 6 pops out from inside the cabinet 1 and is moved inside the cabinet 1 by the courier. This is one working process of the cabinet 1. When the locker 6 pops out, the contact between the power board 501 and the touch switch 202 de-energizes the electromagnetic ring iron 302. After the locker 6 is pushed into the cabinet 1, the contact between the power board 501 and the touch switch 202 does not de-energize the electromagnetic ring iron 302. This is the energization of the electromagnetic ring iron 302. After the electromagnetic ring iron 302 is energized, it attracts the metal ring 802, thereby moving the metal ring 802 towards the connecting block 3. Then, the metal ring 802 drives the adjusting rod 803 and the automatic push plate 8 to move to the inside of the separating ring plate 5 through the adjusting arc block 804. Therefore, the automatic push plate 8 no longer pushes the locker 6, thus keeping the locker 6 stably inside the storage opening 203.

[0051] Assembly posts 103 are fixed at the four corners of the left side of the cabinet 1. The outer side wall of the assembly post 103 has a through hole 104 at the position corresponding to the middle of the left side wall of the cabinet 1. The outer right side wall of the cabinet 1 has an assembly hole 107 at the position corresponding to the assembly post 103. The inner side wall of the assembly hole 107 has a push hole 106 at the position corresponding to the middle of the right side wall of the cabinet 1. The push hole 106 is equipped with a progressive assembly rod 10. The inner side wall of the right side wall of the cabinet 1 has a through hole 109 at the position corresponding to the push hole 106. The through hole 109 is fixed with a secondary control motor 9. The outer side wall of the progressive assembly rod 10 is fixed with a progressive rack 1001 near the through hole 109. The shaft end of the secondary control motor 9 is fixed with a progressive gear 901, and the progressive gear 901 meshes with the corresponding progressive rack 1001.

[0052] With the above structure, when multiple self-service lockers need to be assembled together, the assembly columns 103 and assembly holes 107 on the two self-service lockers are matched one-to-one, and the assembly columns 103 are moved into the corresponding assembly holes 107. As a result, the locking holes 104 on the assembly columns 103 will be aligned with the corresponding push holes 106. At the same time, the administrator obtains the operation authority of the main control panel 101 and controls the secondary control motor 9 to rotate forward. Therefore, the secondary control motor 9 will advance the rotation of the gear 901, which in turn drives the movement of the gear rack 1001. The gear rack 1001 then drives the advancing assembly rod 10 to move into the locking hole 104 on the assembly column 103. As a result, the assembly column 103 is locked inside the assembly hole 107, thus assembling the self-service lockers together.

[0053] Among them, such as Figure 6 , 7As shown in Figures 8 and 13, a self-lifting opening 105 is provided in the middle of the front side wall of the cabinet 1. An intelligent cabinet door 102 is installed inside the self-lifting opening 105. A main control panel 101 is fixed on the front side wall of the cabinet 1 directly above the self-lifting opening 105. A storage opening 203 is provided on the side wall of the sealing ring plate 2 at the position corresponding to the self-lifting opening 105. Through the electrical connection between the intelligent cabinet door 102 and the main control panel 101, the partition ring plate 5 will drive the information sensor 502 on the partition ring plate 5 to transmit the correct information to the infrared receiver 204, and then transmit it to the main control panel 101 to control the opening of the intelligent cabinet door 102.

[0054] Among them, such as Figure 4 , 10 As shown in Figures 13 and 14, movable holes 602 are provided on the side wall of the movable plate 601 at positions corresponding to the return springs 603. Movable rods 506 are fixed to the inner side of the movable square opening 505 at positions corresponding to the movable holes 602. The movable plate 601 is slidably sleeved on the corresponding movable rods 506 through the movable holes 602, and the return springs 603 are slidably sleeved on the corresponding movable rods 506. When the movable plate 601 moves inside the movable square opening 505, the movable holes 602 on the movable plate 601 will... The movable rod 506 slides on the outer side wall. The inner side wall of the sealing ring plate 2 is fixed with a buffer pad 205 at the position corresponding to the partition ring plate 5. Foam pads 604 are fixed on the inner side of the storage cabinet 6. When fresh food is put into the storage cabinet 6, because there are foam pads 604 inside the storage cabinet 6 and buffer pads 205 inside the sealing ring plate 2, when the storage cabinet 6 is rotated, the fresh food inside the storage cabinet 6 is cushioned by the foam pads 604 and buffer pads 205, thus ensuring that the fresh food will not be easily damaged.

[0055] Among them, such as Figure 5 , 9 As shown, the outer sidewall of the movable cylinder 301 is provided with adjustment ports 303 corresponding to the positions of the adjustment arc blocks 804. The adjustment arc blocks 804 pass through the corresponding adjustment ports 303. The metal rings 802 are sleeved on the corresponding outer sidewalls of the movable cylinder 301. The inner sides of the sealing ring plates 2 on the left and right sides of the connecting round block 3 are provided with mounting ring frames 7. The mounting ring frames 7 are fixedly connected to the connecting round block 3 and the sealing ring plates 2 respectively. The shaft end of the main control motor 4 is fixedly connected to the corresponding mounting ring frames 7. When the automatic push plate 8 is pushed and moved by the push spring 801, the automatic push plate 8 will drive the adjustment rod 803 to move inside the movable cylinder 301. At the same time, the adjustment rod 803 will drive the adjustment arc blocks 804 to slide inside the adjustment ports 303. Simultaneously, the adjustment arc blocks 804 will drive the metal rings 802 to slide on the outer side of the movable cylinder 301.

[0056] This invention also provides a temperature control method for multi-temperature zone fresh food self-pickup lockers:

[0057] The entire self-service locker is connected to an external power source and network. Since the cooler 201 inside the locker is connected to the main control panel 101, when adjusting the temperature inside the locker, the external administrator can obtain operating access to the main control panel 101. At this time, the administrator can operate the main control panel 101 to control the cooler 201 and regulate the temperature inside the locker through the cooler 201.

[0058] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.
