Description

Technical Field

[0001] This utility model relates to the material cylinder and liquid injection mechanism of a snow melting machine. Background Technology

[0002] A slush machine, also known as a smoothie machine or ice cream maker, is used to turn liquid beverages into a slushy or iced drink. The container receives the external liquid beverage and cools and stirs it within. An inlet is located at the top of the container, which is sealed with a flip-up or sliding cap. Commercial slush machines typically have a large container volume and are marked with an upper limit for liquid filling or slush filling; sufficient buffer space must be left above to prevent the slush from overflowing from the inlet.

[0003] To minimize the volume of the material cylinder in a household snow melter, such as the snow melter disclosed in application publication number CN119453358A, the material cylinder is equipped with a feed inlet and a cover that can be movably opened and closed on the feed inlet; a baffle plate is provided inside the material cylinder to prevent material from overflowing out of the material cylinder, and a sliding plate is provided inside the material cylinder below the feed inlet. The sliding plate extends laterally from the side wall of the inner cavity of the material cylinder and is inclined. The material overflow is prevented by the one-way opening of the baffle plate; another application publication A snow melting machine with CN119054766A has a feeding baffle below the feed inlet. The feeding baffle has an elongated feeding hole. After the liquid enters the feed inlet, it first falls into the feeding baffle and then enters the storage chamber through the feeding hole of the feeding baffle. When freezing and when the ice sand flows in the storage hood, because the feeding hole is elongated and its length is much greater than its width, it forms a narrow shape, making it difficult for the ice sand to be discharged from the narrow hole. Therefore, it can prevent the generated ice sand from flowing back.

[0004] Both of the above solutions have certain drawbacks: the first type of baffle can be opened by external force, which poses a safety hazard for household slush machines, as users or children may accidentally stick their fingers in and get injured; the second type of feed baffle has an irregular shape, which makes it difficult to process and clean, and the production and maintenance costs are very high. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a liquid injection mechanism for a material cylinder that is relatively simple in structure, has a high safety factor, is easy to process and easy to maintain in daily household use, so as to overcome the above-mentioned defects in the prior art.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the liquid injection mechanism of the material cylinder is located at the top of the material cylinder of the snow melting machine, including a liquid injection port and a cover. The liquid injection port is a downward recess located at the top of the material cylinder. The recess includes a side wall and a filter plate connected to each other. All or part of the filter plate is a flat plate. The filter plate has a number of filter holes. The filter holes are set to prevent the user's fingers from passing through.

[0007] Furthermore, each of the filter holes has at least one cross-sectional diameter in the vertical direction that is less than or equal to 12 mm.

[0008] Furthermore, the sidewall and the filter plate are detachably connected via a first connecting structure.

[0009] Furthermore, the sidewall and the top of the material cylinder are detachably connected via a second connecting structure.

[0010] Furthermore, both the first and second connecting structures can only be disconnected within the internal space of the material cylinder.

[0011] Furthermore, the top opening of the filter hole is located on the top surface of the filter plate, and the end opening of the filter hole is located on the bottom surface of the filter plate. The smaller of the diameter of the top opening and the diameter of the end opening is less than or equal to 12 mm.

[0012] Furthermore, the end opening of the filter pore is located below the filter plate.

[0013] Furthermore, the ends of the filter holes are flexible.

[0014] Furthermore, the top of the material cylinder is integrally formed with the side wall and the filter plate.

[0015] Furthermore, the inner wall of the material cylinder is provided with a flow guiding mechanism.

[0016] Compared with the prior art, the advantages of this utility model are that by setting filter plates and corresponding filter holes, the structure of the liquid injection mechanism is simplified and the production cost is reduced while ensuring user safety; the detachable filter plates, side walls and top of the material cylinder are easy to disassemble and clean, and different filter plate components can be replaced as needed to optimize the user experience.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Reference Figure 1-7 The snow melting machine of this utility model includes a material cylinder 100, a discharge nozzle 300 located at the first end of the material cylinder 100, and a handle 200 for opening and closing the discharge nozzle 300. The second end of the material cylinder 100 is a connection port 102. The internal space 104 of the material cylinder 100 is used to accommodate materials and a mixer (not shown in the figure). The material cylinder 100 includes a liquid injection port located at the top of the material cylinder 100, which is closed by a cover 110. The cover 110 is rotatably or slidably connected to the material cylinder 100. Figure 1-5 As shown, one end of the cover 110 is rotatably connected to the rotating shaft 122. The liquid injection port is formed by a downward recess at the top of the material cylinder 100. This recess includes interconnected sidewalls 123 and a filter plate 120. The filter plate 120 is formed at the lowest point of the recess. All or part of the filter plate 120 is a flat plate and is connected to or integrally formed with the sidewalls 123. The filter plate 120 is provided with a plurality of filter holes 121, which penetrate the filter plate 120.

[0028] In one embodiment, the thickness of the filter plate 120 is negligible, and the minimum diameter D of a single filter hole 121 is less than or equal to 12 mm to ensure that a user's finger cannot pass through the filter hole 121. "Cannot pass through" means that the finger cannot enter or, if it does enter, cannot exit. In this embodiment, the lowest point of the filter plate 120 (or the bottom surface of the filter plate 120 when the filter plate 120 is entirely flat) has a safe distance from the outer edge of the agitator. In other words, the lowest point of the filter plate 120 must be higher than the upper limit of the material (slushie) in the material cylinder 100 to prevent the material (slushie) from overflowing backwards from the filter hole 121. The safe distance is the distance that prevents the material (slushie) from overflowing backwards.

[0029] In the second embodiment, as Figure 6As shown, the filter plate 120 has a certain thickness H, and the diameter of the filter hole 121 on the top surface of the filter plate 120 (i.e., the top opening) is greater than the diameter of any part below it. Therefore, the diameter of at least one part of the filter hole 121 in the vertical direction should be less than or equal to 12 mm to ensure that even if a user's finger is inserted into the filter hole 121 from the top opening, it cannot be pulled out from the bottom opening. For example, the cross-section of the filter hole 121 in the vertical plane can be funnel-shaped, inverted funnel-shaped, or hourglass-shaped. That is, when the diameter of the filter hole 121 is equal in any cross-section, then the diameter should be less than or equal to 12 mm; when the diameters of the filter hole 121 are unequal in any cross-section, then the diameter in at least one cross-section should be less than or equal to 12 mm.

[0030] In the third embodiment, as Figure 7 As shown, the thickness H of the filter plate 120 is negligible. The filter holes 121 extend downwards from the bottom surface of the filter plate 120 to form a short tube. The filter holes 121 serve as the inlet of the short tube. The maximum diameter of the short tube inlet (i.e., the top opening of the filter holes 121) is greater than the maximum diameter of the bottom end of the short tube, and the maximum diameter of the bottom end of the short tube is less than or equal to 12 mm. This ensures that even if a user's finger is inserted into the short tube, it cannot pass through. For example, the cross-section of the short tube in the vertical plane can be a trapezoid, wider at the top and narrower at the bottom. Furthermore, when the snow melting machine is operating, the agitator (not shown in the figure) is located in the internal space 104 of the material cylinder 100 (e.g., ...). Figure 5 As shown, when the short tube rotates, the end of the tube will not interfere with the stirrer, but will maintain a safe distance from the outer edge of the stirrer. In one embodiment, the short tube has a flexible end.

[0031] In the second and third embodiments described above, because the diameter of the filter hole 121 is wider at the top and narrower at the bottom, it is difficult for the material (slushie) to overflow even when it is pushed to the vicinity of the end of the filter hole 121 and then back into the filter hole 121. Especially in the third embodiment, when the end of the filter hole 121 (short tube) is flexible, the flexible end is pushed by the material (slushie) (usually along...). Figure 5 The arrow (in the direction of the arrow) bends or even swings, making it more difficult for the material (smoothie) to enter.

[0032] The shape of the filter hole 121 can be arbitrary, such as round, square, oval, triangular, or any polygon, but it must be ensured that the user's fingers cannot pass through the filter hole 121.

[0033] In one embodiment, such as Figure 3 and Figure 5As shown, the filter plate 120 and the side wall 123 are detachably connected via a first connecting structure (not shown in the figure), and the first connecting structure can only be accessed by the user after the material cylinder 100 has been removed from the snow melting machine. Specifically, one end of the material cylinder 100 is a discharge nozzle 300, and the other end is a connection port 102, which is used to insert the agitator and connect to the main body of the snow melting machine. In this embodiment, after the user removes the material cylinder 100 from the snow melting machine, the connection port 102 is exposed to the user's view, at which point the user can enter the internal space 104 through the connection port 102 and touch the first connecting structure. For example, the outer side of the sidewall 123 has a slot, and the filter plate 120 has a protruding edge that mates with the slot; or the sidewall 123 is threadedly connected to the filter plate 120. Regardless of the type of detachable connection, this first connection structure cannot be disengaged without external force from the outside. That is, the user cannot disengage the connection between the filter plate 120 and the sidewall 123 from inside the recess, but can only disengage it by entering the internal space 104 through the connection port 102. The filter plate 120 and the sidewall 123 can only be disengaged within the internal space 104. A corresponding safety locking mechanism can be provided on the outer surface of the recess or on the outside. This safety locking mechanism can only be accessed by the user after entering the internal space 104. Those skilled in the art can conceive of specific locking mechanisms, which will not be elaborated further.

[0034] In another embodiment, the sidewall 123 is integrally formed with the filter plate 120, and the top of the material cylinder 100 is detachably connected to the sidewall 123 via a second connecting structure (not shown in the figure). The second connecting structure can only be accessed by the user after the material cylinder 100 has been removed from the snow melting machine, and the principle is the same as the first connecting structure, that is, the top of the material cylinder 100 and the sidewall 123 can only be disconnected within the internal space 104. In one embodiment, both the first connecting structure and the second connecting structure can be present simultaneously.

[0035] In another embodiment, the height of the sidewall 123 is shortened or even degenerated and disappears, so that the filter plate 120 is directly and detachably connected to the top of the feed cylinder 100. The trade-off is that when the user pours liquid beverage into the feed cylinder 100, the speed must be slowed down, otherwise the liquid beverage may overflow because the indentation is almost non-existent and it will not have time to enter the feed cylinder 100 through the filter hole 121.

[0036] The method of integrally forming the top of the material cylinder 100 with the side wall 123 and the filter plate 120 is a simpler implementation method. However, since it is not detachable, the cleaning process and cleaning effect after use may be worse.

[0037] The filter plate 120 is designed to be detachable. Another purpose is to allow the filter plate 120 to be replaced with different functions according to the user's different needs. For example, when it is necessary to dispense liquid beverages with relatively large particles (such as fruit juice with pulp particles), it can be replaced with a filter plate 120 with larger filter holes 121; when it is only necessary to dispense liquid beverages without particles, it can be replaced with a filter plate 120 with smaller filter holes 121, such as a filter screen with a mesh size of 2 mesh or greater.

[0038] In one embodiment, such as Figure 5 As shown, a flow guiding mechanism is provided at the upper part of the inner wall 105 of the material cylinder 100. The flow guiding mechanism is used to prevent the material (slushie) from accumulating and sticking to the upper part of the inner wall 105 of the material cylinder 100. The flow guiding mechanism includes at least a horizontal flow guiding plate 131. One end of the horizontal flow guiding plate 131 is connected to the inner wall 105 of the material cylinder 100 and extends outward from the inner wall 105 in a generally horizontal or upwardly inclined direction. The angle α between the horizontal flow guiding plate 131 and the horizontal plane is greater than or equal to 0 degrees and less than 90 degrees. In some embodiments, the flow guiding mechanism also includes a vertical flow guiding plate 132. The vertical flow guiding plate 132 is connected to the other end of the horizontal flow guiding plate 131, extends upward and is not connected to the inner wall 105 of the material cylinder 100; in other embodiments, the vertical flow guiding plate 132 extends upward and is connected to the inner wall 105 of the material cylinder 100.
