Description

Technical Field

[0001] The utility model relates to the technical field of beverage mixing machines, in particular to a slurry box for beverage mixing machines. Background Art

[0002] At present, there are two main types of concentrated raw material packaging suitable for beverage dispensers on the market: one is BIB bag soft packaging (i.e. bags made of multi-layer composite films), and the other is plastic bottle packaging (i.e. 1-2L PET bottle packaging for general fast-moving channels). These two types of packaging have their own shortcomings: when using BIB bag soft packaging concentrated raw materials, first of all, professional filling equipment is required for raw material production, and secondly, when the soft packaging is used on the equipment, there will be a certain amount of residual loss during use, and the operation of replenishing raw materials is also relatively cumbersome; when using plastic bottle packaging, on the one hand, there will be a variety of bottle shapes due to different raw material manufacturers. In this way, when it is directly used on the equipment, it will cause the structure for placing the bottle inside the equipment to be difficult to standardize, resulting in low equipment space utilization. On the other hand, the specifications of this type of packaging are generally small, which will make the terminal replenishment of raw materials frequent. In addition, it must be used with a straw to extract the raw materials, which is relatively cumbersome. Utility Model Content

[0003] In order to overcome the above-mentioned defects, it would be advantageous for the utility model to provide a slurry box for a beverage mixing machine to solve the application pain points of the existing packaging.

[0004] In order to achieve the above-mentioned object, the utility model provides a slurry box for a beverage mixing machine, which comprises:

[0005] A box body, the box body having an open top, an inclined bottom and a slurry outlet, the slurry outlet is located at the lowest point of the inclined bottom and opens forward;

[0006] A box cover, which is detachably snap-fitted to the top of the opening of the box body;

[0007] A valve joint assembly is configured to have an inner end detachably connected to a slurry outlet of a box body and an outer end detachably connected to a BIB joint on a beverage mixing machine. The valve joint assembly is provided with a one-way check structure between its inner and outer ends. The one-way check structure is configured to be in a fluid sealing state before the valve joint assembly is connected to the BIB joint and to be in a fluid connecting state after the valve joint assembly is connected to the BIB joint.

[0008] Compared with the prior art, the utility model has many advantages: 1) by providing a standard packaging box (that is, the box design of the utility model is used on the beverage mixing machine equipment), the slurry (that is, the concentrated original slurry) can be stored and used on the equipment, which better solves the application pain points of the above-mentioned two existing packaging solutions; 2) The standard design can fully maximize the use of the space inside the equipment and effectively reduce the frequency of replenishing raw materials during use; 3) The production and storage of raw materials can still use the existing packaging on the market, and only need to pour the box of the utility model before use, and the detachable snap-in connection of the box body and the box cover makes this operation convenient to implement; 4) The one-way check structure enables the valve joint assembly to present two states before and after connection with the BIB joint: fluid sealing state and fluid connection state; 5) The valve joint assembly and the valve joint of the BIB bag soft packaging, that is, the BIB joint, can be directly connected, so that the connection structure and related components in the equipment do not need to be adjusted.

[0009] Further, the valve connector assembly includes a valve connector, a ejector pin and a silicone spring sheet, wherein the valve connector includes an internal threaded end constituting the inner end of the valve connector assembly, an external threaded end constituting the outer end, and an intermediate transition portion having an inner cavity and an outer partition wall, the outer partition wall is provided with a central mounting hole and a circle of slurry through holes arranged around the central mounting hole; the ejector pin is movably installed through the outer partition wall via the central mounting hole; the silicone spring sheet is installed in the inner cavity in an elastically deformed manner under compression and has a circle of liquid through holes; and wherein the inner cavity, the outer partition wall, the ejector pin and the silicone spring sheet constitute the above-mentioned one-way check valve. The structure is characterized in that the inner cavity is arranged so that before the external threaded end of the valve connector is connected to the BIB connector, the silicone spring sheet is elastically deformed in the inner cavity and presses against the outer partition wall, so that the valve connector is in a fluid-tight state; and after the external threaded end of the valve connector is connected to the BIB connector, the ejector pin is arranged so that it can be pushed by the BIB connector to move toward the inside of the inner cavity, and then press against the silicone spring sheet to make it break away from the contact with the outer partition wall and make the internal threaded end and the external threaded end of the valve connector communicate via the inner cavity, a circle of liquid holes and a circle of slurry holes, so that the valve connector is in a fluid-connected state.

[0010] Through the above-mentioned structural arrangement, the ejector pin can be installed into the inner cavity of the intermediate transition portion from one side of the internal thread end of the valve connector, and penetrate the central mounting hole to be installed on the outer partition wall, and the silicone spring sheet can be installed in the inner cavity by utilizing its elastic deformation to be squeezed, thereby realizing the fluid sealing of the valve connector by the silicone spring sheet pressing against or squeezing the outer partition wall, and realizing the fluid communication of the valve connector by the silicone spring sheet being separated from the contact with the outer partition wall under the push of the ejector pin.

[0011] Furthermore, a circle of limiting ribs is provided on the inner wall of the middle transition portion near the inner thread end, and an inner cavity is formed between the circle of limiting ribs and the outer partition wall, and an annular flange is provided on the inner side of the outer partition wall. When the valve joint is in a fluid sealing state, the silicone spring sheet elastically deforms and presses against the annular flange, and when the valve joint is in a fluid communication state, the silicone spring sheet breaks away from the contact with the annular flange so that a circle of liquid holes is fluidly connected with a circle of slurry holes.

[0012] Through the above-mentioned structural arrangement, the silicone spring can achieve fluid sealing and fluid communication states through elastic deformation in the internal cavity.

[0013] Furthermore, the ejector pin has a circular cake portion and a needle-shaped portion, the circular cake portion is located in the inner cavity, and the needle-shaped portion is movably mounted in the central mounting hole of the outer partition wall.

[0014] Through the above-mentioned structural setting of the ejector pin, when the BIB connector is connected to the valve connector, the circular part can push the silicone spring by pushing the needle-shaped part, thereby realizing the conversion between the fluid sealing state and the fluid connecting state of the valve connector.

[0015] Furthermore, the silicone spring includes a bowl-shaped portion and an arc-shaped portion located on the outer circle of the bowl-shaped portion, wherein the bowl-shaped portion and the arc-shaped portion are warped in opposite directions, the inner concave surface of the bowl-shaped portion faces the round cake portion of the ejector pin, a circle of liquid holes is arranged on the arc-shaped portion, and the outer edge of the arc-shaped portion is suitable for elastically pressing against the limiting rib plate, and the bottom end surface of the arc-shaped portion is suitable for elastically pressing against the annular flange of the outer partition wall.

[0016] Through the above-mentioned structural setting of the silicone spring, the silicone spring is more easily squeezed and elastically deformed after being loaded into the content cavity, thereby realizing a fluid sealing state. At the same time, the round cake part of the ejector pin can push the bowl-shaped part toward the inside of the content cavity during the connection process between the valve connector and the BIB connector to realize a fluid connection state.

[0017] Furthermore, the valve joint assembly also includes a silicone O-type gasket, which is installed at the root of the internal thread end.

[0018] The installation of the silicone O-type gasket can prevent slurry leakage from occurring at the connection between the internal thread end of the valve connector and the slurry outlet portion of the box body.

[0019] Furthermore, the slurry outlet is provided with an external threaded portion for connecting with the internal threaded portion of the valve joint; and the box body is provided with a gripping portion for being grasped by one hand.

[0020] Due to the arrangement of the external threaded portion of the slurry outlet and the internal threaded portion of the valve connector, the connection between the two is very convenient and quick. At the same time, due to the arrangement of the gripping portion on the box body, the operation of taking out and placing the material box with one hand becomes very convenient.

[0021] Furthermore, the box cover is provided with air holes for air pressure balance; and each corner inside the box body is chamfered with an arc.

[0022] The air holes on the box cover can balance the internal negative pressure formed when the raw materials in the box are continuously consumed, avoiding the box body being compressed and deformed and the raw material output flow rate changing (becoming smaller) due to the internal and external pressure difference (lower than the external atmospheric pressure); at the same time, since the inside of the box is smooth and has no dead corners (arc chamfers), and the slurry outlet is located at the lowest liquid level, the slurry is first-in-first-out in terms of structure, and it is also convenient for cleaning the box.

[0023] Furthermore, the box cover is a plastic cover body processed by injection molding, and the box body is a plastic box processed by blow molding. In addition, the box cover is provided with an elastic card slot, and the box body is provided with an elastic buckle suitable for elastically engaging and disengaging from the elastic card slot.

[0024] Through the above-mentioned structural arrangement, the box body and the box cover themselves have sufficient rigidity and strength, and through the adaptation design of the elastic buckle and the elastic slot, the installation and removal operations of the box cover on the box body become easy.

[0025] Furthermore, the outer circumferential surface of the intermediate transition portion of the valve joint is a smooth surface or a knurled surface or a ridge surface with uniformly distributed ridges.

[0026] Through the above structural setting, customers can choose the desired valve joint design according to their own needs.

[0027] These and other aspects of the present invention will be more clearly explained by referring to the embodiments described below. BRIEF DESCRIPTION OF THE DRAWINGS

These expressions are appropriate when the various parts of the disclosed embodiments are located in the positions shown in the figures, and if the position or reference system of the disclosed embodiments changes, these expressions should also change according to the change of the position or reference system of the disclosed embodiments.

[0040] like Figures 1 to 9 As shown, a slurry box 100 for a beverage mixing machine according to a specific embodiment of the present invention comprises a box body 1, a box cover 3 and a valve joint assembly, wherein the valve joint assembly comprises a valve joint 4, a ejector pin 6, a silicone spring 8 and a silicone O-type gasket 9. Figure 1 , Figure 4 and Figure 5 As shown, the box body 1 has an open top 10, an inclined bottom 12 and a slurry outlet 14, wherein the inclined bottom 12 means that the bottom wall of the box body 1 is inclined; the slurry outlet 14 is arranged at the lowest point of the inclined bottom 12 of the box body 1 and opens forward; each corner of the box body 1, such as the corner 17 (see Figure 4 ) are all chamfered, which means that the box body 1 is smooth without dead corners. This design effectively ensures the first-in-first-out principle of the slurry in the material box, without residue and easy to clean.

[0041] like Figures 1 to 3 As shown, the box cover 3 is detachably snapped onto the open top 10 of the box body 1, and the box cover 3 is provided with an air hole 30 for air pressure balance, so as to balance the internal negative pressure formed when the raw materials in the box body 1 are continuously consumed. In this embodiment, the box cover 3 is a plastic cover body processed by injection molding, and the box body 1 is a plastic box processed by blow molding. This structural design meets the rigidity and strength of the product; the box cover 3 is provided with an elastic card slot 31, and the box body 1 is provided with an elastic buckle 11 suitable for elastic snapping and disengaging from the elastic card slot 31. This structural design makes it easy to disassemble and assemble the box cover 3 and the box body 1, thereby making it easy to pour the slurry from the existing packaging into the material box of the utility model.

[0042] like Figure 1 , Figures 4 to 9 As shown, the valve connector 4 includes an internal threaded end 41 detachably connected to the slurry outlet portion 14 of the box body 1, an intermediate transition portion 43 and an external threaded end 45 detachably connected to the BIB connector (not shown) on the beverage mixing machine, wherein the internal threaded end 41 and the external threaded end 45 respectively constitute the inner end of the valve connector assembly connected to the slurry outlet portion 14 and the outer end connected to the BIB connector on the beverage mixing machine; the intermediate transition portion 43 has an inner cavity 42 and an outer partition wall 44, and the outer partition wall 44 is provided with a coaxially arranged central mounting hole 446 and a circle of slurry through holes 448; the ejector pin 6 is movably installed through the outer partition wall 44 via the central mounting hole 446; the silicone spring sheet 8 is elastically deformed by compression and installed in the inner cavity 42 and has a circle of liquid through holes 80 (see Figure 6 and Figure 7 ).

[0043] In this embodiment, the inner cavity 42, the outer partition wall 44, the ejector pin 6 and the silicone spring sheet 8 constitute a structure of the valve connector assembly that performs a one-way non-return function, namely a one-way non-return structure, and the inner cavity 42 is arranged so that before the external threaded end 45 of the valve connector 4 is connected to the BIB connector, the silicone spring sheet 8 elastically deforms in the inner cavity 42 and presses against the outer partition wall 44, so that the inner cavity 42 is in a fluid-tight state (see Figure 5 ), and after the external threaded end 45 of the valve connector 4 is connected to the BIB connector, the ejector pin 6 can move toward the inner side of the inner cavity 42 under the push of the BIB connector, and then push against the silicone spring 8 to make it break away from the contact with the outer partition wall 44, so that the internal threaded end 41 and the external threaded end 45 of the valve connector 4 are connected to each other through the inner cavity 42, a circle of liquid holes 80 of the silicone spring 8 and the annular through hole 448, so that the valve connector 4 is in a fluid communication state (see Figure 6 ).

[0044] like Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, in this embodiment, a circle of limiting ribs 430 is provided on the inner wall of the intermediate transition portion 43 near the inner thread end 41, and an inner cavity 42 is formed between the circle of limiting ribs 430 and the outer partition wall 44, and an annular flange 440 is provided on the inner side of the outer partition wall 44. When the valve connector 4 is in a fluid-tight state, the silicone spring 8 elastically deforms and presses against the annular flange 440 (that is, the silicone spring 8 and the annular flange 440 are in interference sealing fit), and when the valve connector 4 is in a fluid-connected state, the silicone spring 8 is separated from the contact with the annular flange 440 to form a gap 48, so that a circle of liquid holes 80 thereon are in fluid communication with a circle of slurry through holes 448. In addition, it should be noted that the inner thread end 41 means that the inner surface is a threaded surface, that is, the inner surface is provided with an inner thread, and the outer thread end 45 means that the outer surface is a threaded surface, that is, the outer surface is provided with an outer thread. The material of the valve connector 4 can be plastic or metal, and can be manufactured by mechanical cutting or injection molding.

[0045] For example Figure 5 and Figure 6 As shown, in this embodiment, the ejector pin 6 has a circular portion 60 and a needle portion 66. The circular portion 60 is located in the inner cavity 42, and the needle portion 66 is movably installed in the central mounting hole 446. When the valve connector 4 is connected to the BIB connector on the device, the ejector pin 6 will lift up the silicone diaphragm 8, overcome the elastic force of the silicone diaphragm 8 itself, and the silicone diaphragm 8 will be out of contact with the annular flange 440 of the valve connector 4, so that the gap 48 between the two forms a fluid channel, and the slurry in the box body 1 will pass through a circle of liquid holes 80 of the silicone spring 8, then pass through the gap 48 between the silicone spring 8 and the inner annular flange 440 of the valve connector 4, and finally pass through a gap on the valve connector 4. The circle of slurry through holes 448 and the external threaded end 45 output outward; when the valve connector 4 is detached from the BIB connector on the equipment, the elastic diaphragm 8 will rebound and reset, driving the ejector pin 6 to reset as well, and the silicone diaphragm 8 and the annular flange 440 of the valve connector 4 will elastically contact each other again (that is, they are squeezed against each other without gaps, that is, interference fit). At this time, the circle of liquid holes 80 on the silicone diaphragm 8 and the circle of slurry through holes 448 on the valve connector 4 are no longer connected, blocking the output of the raw materials and playing a one-way check role.

[0046] For example Figure 7 As shown, and refer to Figure 5 and Figure 6In this embodiment, the silicone spring 8 includes an arc portion 84 and a bowl portion 86, wherein the arc portion 84 is located at the outer circle of the bowl portion 86, and the bowl portion 86 and the arc portion 84 are warped in opposite directions (this structure enhances the elastic deformation ability of the silicone spring 8), the bowl portion 86 opens toward the round cake portion 60 of the ejector pin 6 (that is, the inner concave surface of the bowl portion 86 faces the round cake portion 60 of the ejector pin 6), and the circle of liquid holes 80 is arranged on the arc portion 84. The outer edge (that is, the free end) of the arc portion 84 is suitable for elastically pressing against the limiting rib plate 430, and the bottom end surface of the arc portion 84 (that is, the end connected to the bowl portion 86) is suitable for pressing against the annular flange 440 of the outer partition wall 44.

[0047] For example Figure 5 and Figure 6 As shown, and refer to Figure 1 In this embodiment, the silicone O-type gasket 9 is installed at the root of the internal thread end 41 of the valve connector 4, so as to avoid slurry leakage at the connection between the internal thread end 41 of the valve connector 4 and the slurry outlet 14 of the box body 1. It should be noted that, if Figure 8 As shown, the slurry outlet portion 14 is provided with an external threaded portion 141 for connecting with the internal threaded end 41 of the valve connector 4, which makes the connection between the slurry outlet portion 14 and the valve connector 4 convenient and quick.

[0048] For example Figure 1 As shown, it should be noted that, in this embodiment, the box body 1 is provided with a grip portion 13 for single-handed grasping, so that the material box can be conveniently taken out. In addition, although in this embodiment, the outer circumferential surface of the intermediate transition portion 43 of the valve connector 4 is a smooth surface, as shown in FIG. Figure 6 As shown, in another embodiment, the outer circumferential surface of the intermediate transition portion 43 may also be a non-slip surface, such as a knurled surface, or a convex ridge surface with uniformly distributed convex ridges.
