Description

Technical Field

[0001] The present invention relates to the technical field of ice cream vending machines, and particularly to an ice cream vending machine with a self-cleaning structure. Background Art

[0002] Most of the existing ice cream vending machines first stir the ice cream slurry, then cool it according to the set temperature, and press out the processed ice cream through a compression cylinder and a liquid outlet valve. After consumers scan the code or insert coins to pay in front of the ice cream vending machine, the ice cream vending machine will extrude the selected flavor of ice cream. After the ice cream is made, consumers can take away the ice cream carton. In actual use, ice cream often remains at the ice cream extrusion port, which is extremely easy to breed bacteria.

[0003] In view of the above technical problems, the applicant has retrieved some prior arts to clean the residual ice cream at the ice cream extrusion port. For example, the patent publication number is CN216435072U. Its main technical means is to drive the shielding scraper to rotate by turning the handle, so that the shielding scraper is separated from the discharge port to extrude the ice cream. When the ice cream extrusion ends, under the action of the torsion spring, the handle drives the rotating rod to reset, and then the shielding scraper cleans the residual ice cream, so that the ice cream drips into the internal recycling box for collection. After analysis by the applicant, the disadvantages of this technical solution are as follows: the extrusion port is far from the cooling module of the ice cream machine, and the ice cream at the extrusion port will melt. When simply blocking the extrusion port, the ice cream will melt into a liquid state and flow out from the gap, and drip onto the carton tray below. When making carton-packed ice cream, it will contaminate the newly placed carton during the next production, resulting in dirty fingers when consumers take out the made carton ice cream, thus affecting the use experience of the ice cream vending machine. Based on this, the present invention provides an ice cream vending machine with a self-cleaning structure that is simple and ingenious in structure and can automatically clean the ice cream that melts and drips onto the carton tray from the extrusion port. Summary of the Invention

[0004] The purpose of the present invention is to provide an ice cream vending machine with a self-cleaning structure for the deficiencies of the prior art, so as to solve the technical problem that the residual ice cream at the extrusion port melts and drips onto the carton tray, affecting and contaminating the subsequent placed ice cream cartons.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] An ice cream vending machine with a self-cleaning structure includes:

[0007] A vending machine body, which is provided with an operation module, an ice cream extrusion port connected to an ice cream slurry cylinder, and a placement box for carrying a carton tray to place a carton below the ice cream extrusion port;

[0008] A cleaning rod, which is slidably mounted on the carton tray and is driven by a driving component to perform reciprocating linear motion;

[0009] A carton blanking area, a carton blanking area is arranged at one end of the carton tray inside the vending machine body, and an output component for driving the carton to move below the ice cream extrusion port is arranged in the carton blanking area; and

[0010] A cleaning block, which is slidably mounted on the ice cream extrusion port and the two are coaxially arranged. The cleaning block is driven by a rotating component arranged on the vending machine body to rotate at the ice cream extrusion port, and the rotating component is connected to the output component.

[0011] As a further scheme of the present invention: a plurality of grooves are arranged on the cleaning rod, a plurality of round tubes are arranged on the carton tray, and there is a gap between two adjacent round tubes. The plurality of round tubes are engaged with the plurality of grooves.

[0012] As a further scheme of the present invention: the end of the carton tray away from the carton blanking area inside the vending machine body is a decontamination area. The cleaning rod reciprocates between the carton blanking area and the decontamination area, and a to-be-used carton is placed in the carton blanking area.

[0013] As a further scheme of the present invention: a scraping rod is arranged in the decontamination area. When the cleaning rod slides into the decontamination area, the cleaning rod triggers a transmission component to drive the scraping rod to slide on the surface of the cleaning rod.

[0014] As a further scheme of the present invention: the transmission component includes:

[0015] A traction frame, which is fixed on the cleaning rod;

[0016] An inclined plate, which is fixed on the slider, and the inclined plate is slidably matched with the traction frame. The height of the end of the inclined plate close to the carton blanking area is lower than the height of the end away from the carton blanking area; and

[0017] A base, which is fixed on the vending machine body, and the slider is slidably mounted on it. A scraping rod is connected to the slider through an elastic telescopic member. When the cleaning rod slides to the decontamination area, the traction frame abuts against the inclined plate, and at the same time the scraping rod abuts against the cleaning rod.

[0018] As a further scheme of the present invention: the inner bottom surface of the placement box is inclined, and the height of the end away from the carton blanking area is lower than the height of the end close to the carton blanking area. A sewage discharge port is arranged at the end of the placement box away from the carton blanking area, and a garbage bin is arranged at the position below the sewage discharge port inside the vending machine body.

[0019] As a further solution of the present invention: The output component includes a driving source and a limiting block. The limiting block abuts against the to-be-used paper box in the paper box blanking area, and the output end of the driving source is connected to the limiting block.

[0020] As a further solution of the present invention: The rotating component includes:

[0021] A toothed ring, which is coaxially and rotatably connected to the ice cream extrusion port and meshes with a rack slidably mounted on the vending machine body. The toothed ring is fixedly connected to the cleaning block; and

[0022] A positioning seat, which is fixed on the vending machine body and is connected to the rack through an elastic member. A transmission rod is installed on the limiting block, and the moving path of the transmission rod interferes with the position of the rack.

[0023] As a further solution of the present invention: The number of the ice cream extrusion ports is multiple, and each ice cream extrusion port is provided with a cleaning block and a rotating component. The heights of the multiple racks increase in the direction close to the paper box blanking area, and the transmission rod is an electric telescopic structure.

[0024] As a further solution of the present invention: An adsorbent is provided on the ice cream extrusion port. When the cleaning block rotates one circle on the surface of the ice cream extrusion port, the cleaning block contacts the adsorbent.

[0025] The beneficial effects of the present invention:

[0026] (1) In the present invention, before the output component drives the to-be-used paper box to move below the ice cream extrusion port, the driving component first drives the cleaning rod to move from the paper box blanking area to the other end on the paper box tray to clean the paper box tray. Subsequently, the output component drives the to-be-used paper box to move below the ice cream extrusion port, realizing automatic cleaning of the paper box tray before placing the to-be-used paper box below the ice cream extrusion port, and avoiding the problem that the ice cream remaining on the ice cream extrusion port after the previous ice cream production melts and drips onto the paper box tray, causing pollution to the to-be-used paper box placed during the production of the new ice cream;

[0027] (2) In the present invention, the output component drives the cleaning block to rotate on the ice cream extrusion port through the rotating component, so that the ice cream extrusion port and the paper box tray can be cleaned synchronously when placing the to-be-used paper box below the ice cream extrusion port, thereby ensuring that the ice cream extruded from the ice cream extrusion port is fresh ice cream and improving the use experience of the ice cream vending machine;

[0028] (3) In the present invention, when the cleaning rod slides to the other end of the paper box tray, it automatically triggers the scraping rod to slide on its surface to scrape the ice cream cleaned on the surface of the cleaning rod. Subsequently, after the cleaning rod is driven by the driving component to reset, it is in a clean state, which is convenient for the next cleaning of the paper box tray;

[0029] (4) In the present invention, after the ice cream is made, when the consumer takes away the paper box, the drive source drives the limiting block and the transmission rod to reset, then the rack loses power, and the elastic force of the elastic member recovering from deformation drives the rack to reset. Then, the cleaning block rotates one circle on the surface of the ice cream extrusion port, realizing the re-cleaning of the ice cream extrusion port. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figures 1 - 11 As shown, the present invention is an ice cream self-service vending machine with a self-cleaning structure, including:

[0045] The vending machine body 1 is provided with an operation module 2, an ice cream extrusion outlet 3 connected to the ice cream slurry tank, and a placement box 5. The placement box 5 is used to carry the paper box tray 4 to place the paper box below the ice cream extrusion outlet 3;

[0046] The cleaning rod 6 is slidably installed on the paper box tray 4 and is driven by the drive assembly 7 to perform reciprocating linear motion;

[0047] The paper box blanking area 10 is provided at one end of the paper box tray 4 in the vending machine body 1, and an output assembly 11 for driving the paper box to move below the ice cream extrusion outlet 3 is provided in the paper box blanking area 10; and

[0048] The cleaning block 12 is slidably installed on the ice cream extrusion outlet 3, and the two are coaxially arranged. The cleaning block 12 is driven by a rotating assembly 13 provided on the vending machine body 1 to rotate on the ice cream extrusion outlet 3, and the rotating assembly 13 is connected to the output assembly 11.

[0049] It should be noted that a carton storage module 17 is provided in the carton blanking area 10, and a manipulator module is also provided in the vending machine body 1. The operation module 2, the ice cream extrusion port 3, the ice cream slurry tank, the manipulator module, and the carton storage module 17 are all connected to the controller. The above modules and the controller are all prior arts, and no improvements have been made to them in this application. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of this application.

[0050] In one case of this embodiment, the driving component 7 can be selected from components such as hydraulic cylinders and air cylinders, or other mechanisms capable of realizing linear motion can also be selected. This embodiment does not make specific limitations here.

[0051] In actual application of this embodiment, in the initial state, the carton to be used is located below the carton storage module 17 in the carton blanking area 10 and is taken and placed by the manipulator module. At this time, the cleaning rod 6 is located in the carton blanking area 10. After a consumer places an order for ice cream at the operation module 2, the controller controls the driving component 7 to drive the cleaning rod 6 to move on the carton tray 4 from the carton blanking area 10 to the other end to clean the carton tray 4. Subsequently, the controller controls the output component 11 to drive the carton to be used to move below the ice cream extrusion port 3, realizing automatic cleaning of the carton tray 4 before placing the carton to be used below the ice cream extrusion port 3, and avoiding the problem that the ice cream remaining at the ice cream extrusion port 3 after previous ice cream production melts and drips onto the carton tray 4, causing pollution to the carton to be used when making new ice cream. During the process of the output component 11 driving the carton to be used to move below the ice cream extrusion port 3, the output component 11 will drive the cleaning block 12 to rotate at the ice cream extrusion port 3 through the rotating component 13, so that the ice cream extrusion port 3 and the carton tray 4 can be cleaned synchronously when placing the carton to be used below the ice cream extrusion port 3, thereby ensuring that the ice cream extruded from the ice cream extrusion port 3 is fresh ice cream and improving the use experience of the ice cream vending machine.

[0052] As Figures 2 - 7 shown, as a preferred embodiment of the present invention, a plurality of grooves 14 are provided on the cleaning rod 6, and a plurality of round tubes are provided on the carton tray 4, and there is a gap between adjacent two round tubes. The plurality of round tubes are engaged with the plurality of grooves 14. In actual application, when there is no consumer placing an order, the ice cream remaining at the ice cream extrusion port 3 melts and drips onto the carton tray 4 and passes through the gap between adjacent round tubes and enters the placement box 5, which can reduce the residual ice cream attached to the carton tray 4. The placement box 5 can be disassembled and cleaned, and the carton tray 4 can be rinsed, improving the cleaning efficiency of the ice cream vending machine.

[0053] As Figures 1 - 7As shown in the figure, as a preferred embodiment of the present invention, the end of the paper box tray 4 in the vending machine body 1 away from the paper box feeding area 10 is a decontamination area, the cleaning rod 6 reciprocates between the paper box feeding area 10 and the decontamination area, and the to-be-used paper boxes are placed in the paper box feeding area 10.

[0054] In one case of this embodiment, a scraping rod 8 is arranged in the decontamination area. When the cleaning rod 6 slides into the decontamination area, the cleaning rod 6 triggers the transmission assembly 9 to drive the scraping rod 8 to slide on the surface of the cleaning rod 6.

[0055] The transmission assembly 9 includes:

[0056] A traction frame 901, which is fixed on the cleaning rod 6;

[0057] An inclined plate 902, which is fixed on the slider 903, and the inclined plate 902 is in sliding fit with the traction frame 901. The height of the end of the inclined plate 902 close to the paper box feeding area 10 is lower than the height of the end away from the paper box feeding area 10; and

[0058] A base 904, which is fixed on the vending machine body 1, and the slider 903 is slidably installed thereon. A scraping rod 8 is connected to the slider 903 through an elastic telescopic member 905. When the cleaning rod 6 slides into the decontamination area, the traction frame 901 abuts against the inclined plate 902, and at the same time the scraping rod 8 abuts against the cleaning rod 6.

[0059] It should be noted that the traction frame 901 is a square frame with a mouth shape, and an inclined surface for sliding fit with the inclined plate 902 is arranged thereon; the elastic telescopic member 905 is a structure formed by nesting multiple-stage pipe fittings. In actual application, a gear rack or an electric telescopic rod structure can also be used. This embodiment does not make specific limitations here.

[0060] In actual application of this embodiment, when the cleaning rod 6 slides to the decontamination area, the traction frame 901 abuts against the inclined plate 902, and at the same time the scraping rod 8 abuts against the cleaning rod 6. Then the cleaning rod 6 continues to slide into the decontamination area, that is, the cleaning rod 6 moves in the direction away from the paper box feeding area 10. The traction frame 901 with a constant height slides relatively with the inclined plate 902. The inclined plate 902 drives the slider 903 to descend on the base 904, so the height of the scraping rod 8 decreases. At the same time, the distance between the cleaning rod 6 and the base 904 gradually shortens. When the scraping rod 8 descends, the elastic telescopic member 905 gradually contracts, and the scraping rod 8 gradually approaches the base 904. In this way, when the cleaning rod 6 slides to the other end of the paper box tray 4, the scraping rod 8 can be automatically triggered to slide on its surface to scrape the ice cream cleaned on the surface of the cleaning rod 6; then after the cleaning rod 6 is driven to reset by the driving assembly 7, it is in a clean state, which is convenient for the next cleaning of the paper box tray 4.

[0061] As Figures 4 - 6As shown, as a preferred embodiment of the present invention, the inner bottom surface of the placement box 5 is inclined, and the height of the end away from the paper box blanking area 10 is lower than the height of the end close to the paper box blanking area 10. A sewage outlet 15 is provided at the end of the placement box 5 away from the paper box blanking area 10, and a garbage bin is provided inside the vending machine body 1 at a position below the sewage outlet 15.

[0062] In actual application of this embodiment, when there is no consumer placing an order, the ice cream remaining at the ice cream extrusion port 3 melts and drips and passes through the gaps between adjacent circular tubes, and the ice cream scraped by the scraping rod 8 during sliding cleaning on the surface of the cleaning rod 6 will all enter the placement box 5 and flow along its inclined inner bottom surface towards the sewage outlet 15, and finally pass through the sewage outlet 15 and fall into the garbage bin for collection, thereby realizing the cleaning and collection of the remaining ice cream.

[0063] As Figures 7 - 11 shown, as a preferred embodiment of the present invention, the output assembly 11 includes a driving source 1101 and a limiting block 1102. The limiting block 1102 abuts against the paper box to be used in the paper box blanking area 10, and the output end of the driving source 1101 is connected to the limiting block 1102.

[0064] In one case of this embodiment, the driving source 1101 can be selected from components such as hydraulic cylinders and air cylinders, or other mechanisms capable of realizing linear motion can also be selected. This embodiment does not make specific limitations here.

[0065] In actual application of this embodiment, the limiting block 1102 is an arc-shaped block that fits the outer wall of the paper box. The driving source 1101 drives the limiting block 1102 to drive the paper box to move below the ice cream extrusion port 3 to receive the ice cream extruded from the ice cream extrusion port 3 subsequently.

[0066] As Figures 7 - 11 shown, as a preferred embodiment of the present invention, the rotating assembly 13 includes:

[0067] A toothed ring 1301, which is coaxially rotatably connected to the ice cream extrusion port 3 and meshes with a rack 1302 slidably mounted on the vending machine body 1. The toothed ring 1301 is fixedly connected to the cleaning block 12; and

[0068] A positioning seat 1304, which is fixed to the vending machine body 1 and is connected to the rack 1302 through an elastic member 1305. A transmission rod 1303 is installed on the limiting block 1102, and the moving path of the transmission rod 1303 interferes with the position of the rack 1302.

[0069] In one case of this embodiment, the elastic member 1305 can be selected such as Figure 9The shown spring can also be replaced with other elastic components, such as silica gel columns, elastic sheets, etc., which are not specifically limited in this embodiment.

[0070] In the actual application of this embodiment, when the driving source 1101 drives the limiting block 1102 to drive the paper box to move downward below the ice cream extrusion port 3, the transmission rod 1303 pushes the rack 1302 to move, and the elastic member 1305 is stretched. Then the toothed ring 1301 rotates on the surface of the ice cream extrusion port 3, and further drives the cleaning block 12 to rotate on the surface of the ice cream extrusion port 3, so as to realize the cleaning of the surface of the ice cream extrusion port 3; when the ice cream making is over and the consumer takes away the paper box, the driving source 1101 drives the limiting block 1102 and the transmission rod 1303 to reset. Then the rack 1302 loses power, and the elastic force of the elastic member 1305 recovering from deformation drives the rack 1302 to reset. Then the cleaning block 12 rotates one circle on the surface of the ice cream extrusion port 3, realizing the secondary cleaning of the ice cream extrusion port 3.

[0071] Such as Figures 1 - 11 As shown, as a preferred embodiment of the present invention, the number of the ice cream extrusion ports 3 is multiple, and a cleaning block 12 and a rotating assembly 13 are arranged on each ice cream extrusion port 3. The heights of the multiple racks 1302 increase in the direction close to the paper box blanking area 10, and the transmission rod 1303 is an electric telescopic structure.

[0072] In one case of this embodiment, the transmission rod 1303 is a structure formed by nesting multiple-stage pipe fittings. In actual application, a gear-rack or electric telescopic rod structure can also be adopted, which is not specifically limited in this embodiment.

[0073] In the actual application of this embodiment, the multiple ice cream extrusion ports 3 respectively correspond to multiple flavors of ice cream. After the consumer selects the ice cream of the corresponding flavor on the operation module 2, the controller controls the transmission rod 1303 to extend to the height of the rack 1302 on the ice cream extrusion port 3 of the corresponding flavor. The higher the height of the rack 1302 closer to the paper box blanking area 10, the transmission rod 1303 will not push the other racks 1302 passing by during the movement; when the limiting block 1102 pushes the paper box below the ice cream extrusion port 3, the rack 1302 on this limiting block 1102 has pushed the rack 1302 to move, and the elastic member 1305 has been stretched, and the cleaning block 12 has rotated one circle on the surface of the ice cream extrusion port 3, that is, the surface of the ice cream extrusion port 3 can be automatically wiped and cleaned before extruding the ice cream, ensuring that the ice cream extruded with different flavors is fresh.

[0074] Such as Figures 8 - 10 As shown, as a preferred embodiment of the present invention, an adsorbent 16 is arranged on the ice cream extrusion port 3. After the cleaning block 12 rotates one circle on the surface of the ice cream extrusion port 3, the cleaning block 12 contacts the adsorbent 16.

[0075] In one case of this embodiment, the adsorbent member 16 can be made of sponge, or other structural components capable of adsorbing the ice cream on the surface of the cleaning block 12, which will not be elaborated here; in actual application, after the cleaning block 12 rotates one circle on the surface of the ice cream extrusion port 3, the cleaning block 12 contacts the adsorbent member 16, and the adsorbent member 16 can adsorb the ice cream adhered to the surface of the cleaning block 12. After that, just replace the adsorbent member 16 to ensure effective subsequent cleaning.

[0076] Working principle of the present invention: In the above embodiment of the present invention, an ice cream self-service vending machine with a self-cleaning structure is provided. Before the output component 11 drives the paper box to be moved below the ice cream extrusion port 3, the driving component 7 first drives the cleaning rod 6 to move from the paper box blanking area 10 to the other end on the paper box tray 4 to clean the paper box tray 4. Subsequently, the output component 11 drives the paper box to be moved below the ice cream extrusion port 3, realizing automatic cleaning of the paper box tray 4 before placing the paper box to be used below the ice cream extrusion port 3, and avoiding the problem that the ice cream remaining at the ice cream extrusion port 3 after ice cream making melts and drips onto the paper box tray 4, contaminating the paper box to be used when making new ice cream.

[0077] The above has described in detail one embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
