[0002] As a core component of cold beverage equipment, slush machines are widely used in dessert shops, fast food chains, coffee shops, and home consumption scenarios. Slush machines produce frozen foods such as smoothies, ice cream, and sorbets by stirring pre-cooled ingredients at low temperatures and then outputting the product. A slush machine includes a refrigeration evaporator, an ice-scraping and stirring mechanism that works in conjunction with the evaporator, and a material tank fitted around the evaporator and the ice-scraping and stirring mechanism.

[0003] The material hopper is usually fixed to the main body of the snow melting machine. The material hopper is equipped with a discharge port and a valve to open and close the discharge port to discharge frozen food. During the production of frozen food, sometimes it is necessary to discharge a portion of the frozen food in the material hopper to mix with other frozen foods, and sometimes it is necessary to discharge all the frozen food in the material hopper. However, the valve control method cannot quickly discharge all the frozen food.

[0004] In addition, during the production of frozen foods, it may be necessary to add ingredients at different times, and the current slush machine's hopper structure makes it difficult to conveniently add ingredients midway. Utility Model Content

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of 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.

[0025] See Figures 1 to 4 The present invention discloses a material barrel structure, comprising: a barrel body 100, wherein the barrel body 100 is provided with an upward-opening cavity 101, the barrel body 100 is provided with a detachable structure 102 located at the opening edge of the cavity 101, the detachable structure 102 being detachably connected to frozen food manufacturing equipment, the bottom wall of the barrel body 100 being provided with a discharge port 103 communicating with the cavity 101, and the bottom of the barrel body 100 being movably provided with a switch assembly 200 for opening and closing the discharge port 103.

[0026] The above-mentioned material tank structure is applied to the exterior of the refrigeration evaporator of the frozen food manufacturing equipment. When a large amount of frozen food needs to be discharged quickly, the tank body 100 can be removed through the disassembly structure 102, making it convenient for users to transfer or pour the frozen food, thus avoiding the problem of blockage that may occur when the flow rate is high. When a small amount of frozen food needs to be discharged, the discharge port 103 located at the bottom of the tank body 100 can be opened using the switch assembly 200. The frozen food can flow out under the action of gravity and stirring thrust, thus realizing two different discharge methods to meet different usage needs.

[0027] See Figure 2 and Figure 3 In some embodiments of this utility model, the switch assembly 200 includes an operating member 210 movably disposed at the bottom of the barrel 100, a switch member 220 connected to the operating member 210, and an elastic member 230 that drives the operating member 210 to move so as to cause the switch member 220 to seal the discharge port 103. A portion of the operating member 210 extends out of the outer peripheral wall of the barrel 100. It is understood that under the action of the elastic member 230, the switch member 220 can maintain a sealed discharge port 103. When a small amount of frozen food needs to be discharged, the user drives the portion of the operating member 210 extending out of the outer peripheral wall of the barrel 100 to overcome the action of the elastic member 230 and allow the switch member 220 to open the discharge port 103. This facilitates blind operation and makes the operation very convenient.

[0028] See Figure 1 and Figure 3In some embodiments of this utility model, the discharge port 103 is located on the outer periphery of the bottom wall of the barrel 100, the operating member 210 is rotatably mounted on the outer bottom of the barrel 100 via a horizontally arranged rotating shaft 240, the operating member 210 has a pressure plate 211 extending out of the outer periphery of the barrel 100, the switching member 220 is a plug that matches the shape of the discharge port 103, and the elastic member 230 is a torsion spring that passes through the rotating shaft 240 and whose two ends abut against the operating member 210 and the barrel 100 respectively. When the pressure plate 211 is pressed down, it drives the operating member 210 to rotate around the rotating shaft 240 to drive the plug to open the discharge port 103. It should be noted that the discharge port 103 is located on the outer periphery of the bottom wall of the barrel 100, which helps to reduce the length of the operating component 210 and reduce the risk of breakage of the operating component 210. Under the action of the torsion spring, the plug on the operating component 210 rotates upward around the rotating shaft 240 to keep the discharge port 103 sealed. When it is necessary to open the discharge port 103, the user only needs to apply downward force to the pressure plate 211 with his / her finger to overcome the action of the torsion spring and drive the plug to rotate downward around the rotating shaft 240 to open the discharge port 103. After completing a certain output, the user can release his / her hand to reseal the discharge port 103.

[0029] It should be noted that in some embodiments, see [reference needed]. Figure 2 and Figure 3 The container 100 includes an inner container 110 and an outer container 120 fitted outside the inner container 110. The discharge port 103 is provided through the bottom wall of the inner container 110. The bottom wall of the outer container 120 is provided with a notch, which is directly opposite the discharge port 103. At the same time, the notch is used to install and accommodate the above-mentioned operating components 210, rotating shaft 240, plug, etc., so that the operating components 210, rotating shaft 240, and plug will not protrude downward from the outer container 120. Therefore, the container structure containing frozen food can be placed stably on the table.

[0030] It should be noted that after the container 100 is removed from the frozen food manufacturing equipment, the frozen food inside can be directly poured out or transferred, preventing blockages during the discharge of frozen foods such as smoothies, ice cream, and sorbets. However, if ingredients need to be added during the frozen food manufacturing process, the container 100 must also be removed from the equipment, making operation very inconvenient. Therefore, see [link to relevant documentation]. Figures 2 to 4 In some embodiments of this utility model, the upper side wall of the barrel 100 is provided with a feeding port 104 that communicates with the cavity 101. When it is necessary to add raw materials midway, the user can directly input the raw materials into the feeding port 104, which is beneficial to improve the efficiency of making frozen food and also helps the user to freely add different raw materials according to personal preferences to customize frozen food with different flavors.

[0031] See Figure 2 and Figure 3 In some embodiments of this utility model, a feeding tray is protruding from the upper side wall of the barrel 100. The feeding tray has an upward-opening feeding cavity 311. A conveying pipe 312 connected to the replenishment port 104 is provided on one side of the bottom of the feeding cavity 311. A door plate 316 for opening and closing the opening of the feeding cavity 311 is movably disposed on the feeding tray. It is conceivable that in the process of making frozen food, it is necessary to use a sealing plug to block the replenishment port 104, and when inputting raw materials into the replenishment port 104, a hose, funnel or other tools are required, which makes it very inconvenient to input raw materials. The above solution provides a feeding tray on the side of the barrel 100. When the user needs to add raw materials midway, he only needs to drive the door plate 316 to open the opening of the feeding cavity 311 and introduce the raw materials (usually liquids) into the feeding cavity 311. Under the action of pressure difference, the raw materials enter the interior of the barrel 100 along the conveying pipe 312 and the replenishment port 104. Specifically, one side of the door panel 316 is pivotally mounted on the opening edge of the feeding chamber 311. Under the action of gravity, the door panel 316 can automatically close the opening of the feeding chamber 311. The surface of the door panel 316 is also provided with a sealing element that matches the opening edge of the feeding chamber 311.

[0032] See Figure 1 and Figure 2 In some embodiments of this utility model, a handle 300 is provided on the outside of the barrel 100. The handle 300 includes a connector 310 extending radially outward along the barrel 100 and a handle 320 provided on the connector 310 and extending downward along the length of the barrel 100. The feeding chamber 311 and the conveying pipe 312 are both provided on the connector 310, and at least a portion of the connector 310 constitutes the feeding tray. It should be noted that the disassembly structure 102 includes a plurality of rotating latching parts formed on the upper part of the inner peripheral wall of the barrel 100. Correspondingly, the frozen food manufacturing equipment is provided with a rotating mounting groove that cooperates with the rotating latching parts. The handle 300 helps the user to rotate the barrel 100 to remove the barrel 100 and also avoids the palm from touching the outer wall of the barrel 100 and getting frostbite. The connector 310 is a component used to connect the handle 320 and the barrel 100, so that there is a certain distance between the handle 320 and the barrel 100. At the same time, the feeding chamber 311 and the conveying pipe 312 are located on the connector 310. The connector 310 also serves as a feeding tray, thus achieving a dual-purpose effect, which helps to improve the compactness of the barrel structure and reduce the number of parts.

[0033] See Figures 2 to 4In some embodiments of this utility model, the barrel 100 is cylindrical, and the connecting member 310 is provided with an arcuate recess 313 that fits against the outer peripheral wall of the barrel 100. Each end of the arcuate recess 313 is provided with a slot 410. The upper part of the outer peripheral wall of the barrel 100 is provided with an elastic buckle 420 that is detachably connected to the slot 410. The edge of the feeding port 104 is provided with a first sealing ring 500, and the first sealing ring 500 is provided with an annular slot 510 for the end of the conveying pipe 312 pointing towards the feeding port 104 to be inserted. The above barrel structure can be removed from the frozen food manufacturing equipment using the disassembly structure 102. The handle 300 can be removed from the barrel 100 by the cooperation of the elastic buckle 420 and the slot 410, thus disassembling it into multiple parts for easy packaging. This helps to fully utilize the internal space of the packaging and reduces packaging and transportation costs. Furthermore, when the conveying pipe 312 and the feeding port 104 are connected, the first sealing ring 500 is used to seal the connection to prevent leakage of liquid raw materials. When the handle 300 is removed from the barrel 100, not only can the first sealing ring 500 be inspected and replaced, but it also facilitates the cleaning of the inside of the conveying pipe 312 and the feeding port 104, preventing bacterial growth. In addition, the separate structure of the handle 300 and the barrel 100 facilitates the processing and manufacturing of the feeding chamber 311 and the conveying pipe 312, and helps to control dimensional accuracy.

[0034] Specifically, the handle 320 and the connector 310 are an integral plastic structure. The handle 320 is a vertically arranged column. The two slots 410 are symmetrically distributed about the central axis of the handle 320. The two elastic buckles 420 are respectively engaged in the two slots 410, which is conducive to the stable connection between the handle 300 and the barrel 100. It is also conducive to the balance of the force applied by the barrel 100 to the connector 310, reducing the possibility of unilateral damage due to uneven force.

[0035] See Figure 3 and Figure 4In some embodiments of this utility model, the barrel 100 includes an inner barrel 110 and an outer barrel 120 sleeved outside the inner barrel 110. The elastic fastener 420 includes a spring portion 421 formed by a portion of the wall panel of the outer barrel 120 and a hook portion 422 formed at the end of the spring portion 421. The outer barrel 120 is provided with a clearance opening 121 around the spring portion 421, and the hook portions 422 of the two elastic fasteners 420 are arranged opposite to each other. It should be noted that when the barrel 100 and the elastic fastener 420 are made of plastic, the clearance opening 121 will form a leakage opening, causing frozen food to overflow from the clearance opening 121 or allowing external dust and foreign objects to enter the barrel 100 and contaminate the frozen food. Setting the barrel 100 as an inner barrel 110 and an outer barrel 120 sleeved outside the inner barrel 110 can solve the above problems. Two opposing hook portions 422 simultaneously engage with two slots 410. When the handle 300 needs to be removed, simply press the hook portions 422 into the two slots 410 simultaneously with your thumb and forefinger. The operation is very convenient. During this process, the spring portion 421 slightly deforms towards the inner barrel 110 within the clearance opening 121, allowing the handle 300 to be pulled out. After the hook portions 422 enter the corresponding slots 410, the clearance opening 121 helps the spring portion 421 to regain its elastic deformation.

[0036] See Figure 3 and Figure 4 In some embodiments of this utility model, in order to make it easy for the two elastic fasteners 420 to align with the two slots 410, the arc-shaped recess 313 is recessed inward in the direction away from the barrel body 100 and a recessed groove 314 is provided. The bottom of the recessed groove 314 is provided with at least two horizontal positioning posts 610 pointing towards the barrel body 100. The outer peripheral wall of the barrel body 100 is formed with guide sleeves 620 that match the positioning posts 610 one by one. The two slots 410 are provided through the two opposite side walls of the recessed groove 314. Both ends of the arc-shaped recess 313 are provided with guide slopes 315 for guiding the elastic fasteners 420 to enter the slots 410 along the side walls of the recessed groove 314.

[0037] When each positioning pin 610 is inserted into its corresponding guide sleeve 620, the elastic buckle 420 can also be inserted into the preset slot 410, which can effectively prevent the handle 300 from deflecting and avoid the handle 300 from moving around. See [link to relevant documentation]. Figure 2At this time, both the positioning pin 610 and the guide sleeve 620 are located within the recessed portion 314, which does not affect the fit of the arc-shaped recess 313 against the outer circumferential wall of the barrel 100, thus reducing the joint gap. It can be imagined that as the handle 300 moves closer to the barrel 100 to fit the arc-shaped recess 313 against the outer circumferential wall of the barrel 100, the hook portion 422 contacts the guide slope 315, and the spring portion 421 undergoes elastic deformation. After the hook portion 422 moves along the guide slope 315 to enter the slot 410, the spring portion 421 returns to its elastic deformation, thereby completing the quick assembly of the handle 300 onto the barrel 100.

[0038] See Figure 5 This utility model also discloses a frozen food manufacturing device, including the material tank structure of any of the above technical solutions. This frozen food manufacturing device can remove the tank body 100 to quickly discharge a large amount of frozen food from the opening of the cavity 101, or use the switch assembly 200 to open the discharge port 103 located at the bottom of the tank body 100 to output a small amount of frozen food, thereby realizing two different discharge methods to meet different usage needs.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
