[0002] In current milk making machines, the mixing funnel is arranged below the milk powder box, and the powder inlet of the mixing funnel is located just below the powder outlet of the milk powder box. When the milk making machine is making milk, the milk powder in the milk powder box falls from the powder outlet to the powder inlet, and the milk powder will be scattered in the process of falling. Due to the humidity of the air, a small amount of milk powder will be scattered to the inner wall of the powder outlet and stick to it. After long-term use, the powder hanging on the inner wall of the powder outlet of the milk powder box will become thicker and thicker, making the powder outlet of the milk powder box smaller, affecting the normal powder discharge of the milk powder box; in addition, in the process of milk powder falling, a small amount of milk powder may fall on the periphery of the powder inlet, causing waste. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] The present invention provides a mixing funnel assembly for use in a milk mixing machine. The mixing funnel assembly is arranged below a milk powder box 10 of the milk mixing machine (see Figure 3 ), and is installed and matched with the milk powder box 10.

[0026] Reference Figures 1 to 5 In this embodiment, the brewing funnel assembly 20 includes a brewing funnel 21 and a funnel cover 22 covering the top of the brewing funnel 21, and the funnel cover 22 is provided with a powder inlet 221 (refer to Figure 5 ), a powder inlet pipe 23 connected to the powder inlet 221 is provided; the powder inlet pipe 23 includes a docking pipe section 231 located at the top thereof, the docking pipe section 231 is inserted into the powder outlet 11 of the milk powder box 10, and the entire outer side wall of the docking pipe section 231 is adapted to fit with the inner wall of the powder outlet 11.

[0027] Specifically, the brewing funnel assembly 20 also includes a funnel bracket 25 for installing the brewing funnel 21, and the brewing funnel 21 is installed in the funnel bracket 25; a water inlet joint 212 for supplying water into the brewing funnel 21 is provided on the top side wall of the brewing funnel 21, and the water inlet joint 212 is connected to the water supply pipeline interface of the milk brewing machine (usually connected in a quick plug-in manner to facilitate the rapid disassembly and assembly of the brewing funnel assembly 20); the funnel cover 22 is provided with an exhaust port 222 near the front side of the milk brewing machine, and an exhaust channel 251 is correspondingly provided on the front side of the funnel bracket 25 (refer to Figure 4 and Figure 5 ), the water vapor generated when the mixing funnel 21 mixes the milk powder is discharged through the exhaust port 222 and the exhaust channel 251. The funnel bracket 25 is fixed to the housing of the milk mixing machine by clamping, so as to facilitate the direct disassembly and assembly of the funnel bracket 25.

[0028] The technical solution of this embodiment directly connects the milk powder box 10 with the mixing funnel 21 through the powder inlet pipe 23, so that when the milk mixing machine using the mixing funnel assembly 20 is mixing milk, the milk powder in the milk powder box 10 comes out of the powder outlet 11 and directly reaches the mixing funnel 21 through the powder outlet pipe, thereby avoiding the situation that the milk powder drifts to the periphery of the powder inlet 221 and reducing the waste of milk powder; in addition, the entire outer wall of the butt joint pipe section 231 is in contact with the inner wall of the powder outlet 11, that is, the butt joint pipe section 231 covers the inner wall part that it is in contact with, thereby avoiding the situation that the powder hangs on the inner wall of the part, and effectively improving the problem of powder hanging on the powder outlet 11 of the milk powder box 10. Although this will cause the inner wall of the butt joint pipe section 231 and the entire powder inlet pipe 23 to hang on, the mixing funnel 21 can be directly disassembled and assembled along with the funnel bracket 25, so the powder inlet pipe 23 can be directly disassembled for cleaning, which is very convenient.

[0029] In order to make the powder inlet pipe 23 pass the milk powder more smoothly, the powder inlet pipe 23 of this embodiment preferably adopts a vertically arranged straight pipe. It should be noted that in other embodiments, the powder inlet pipe 23 can also be an inclined straight pipe, a curved pipe with a smaller curvature, etc. In addition, the powder inlet pipe 23 of this embodiment can be a circular pipe, a square pipe, a polygonal pipe, etc.; in this embodiment, the powder inlet pipe 23 is preferably a circular pipe, which can facilitate the cleaning of the powder inlet pipe 23 and make the design of the powder inlet pipe 23 and the powder outlet 11 simpler, etc.

[0030] Further, refer to Figure 2 In this embodiment, the top end of the connecting pipe section 231 is preferably flush with the top edge of the powder outlet 11. In this way, the connecting pipe section 231 covers the entire inner wall of the powder outlet 11, and the powder outlet 11 of the milk powder box 10 will no longer have powder hanging, which completely solves the problem of powder hanging at the powder outlet 11 of the milk powder box 10.

[0031] Further, refer to Figure 5In this embodiment, a positioning protrusion 223 is provided on the outer wall of the funnel cover 22, and a positioning recess 211 adapted to the positioning protrusion 223 is provided on the top of the brewing funnel 21, and the positioning protrusion 223 is stuck in the positioning recess 211. Through the cooperation of the positioning protrusion 223 and the positioning recess 211, firstly, a positioning and fixing effect is formed between the funnel cover 22 and the brewing funnel 21, and secondly, a fool-proof effect is provided for the installation of the funnel cover 22 and the brewing funnel 21, so as to avoid the deviation of the powder outlet tube and the powder outlet 11 of the milk powder box 10 caused by the deviation of the funnel cover 22 during installation.

[0032] Further, refer to Figures 2 to 4 ,as well as Figure 6 In this embodiment, the pipe opening of the connecting pipe section 231 is preferably gradually reduced from its bottom end to the top end, that is, the outer wall of the connecting pipe section 231 is tapered, and the inner wall shape of the powder outlet 11 of the milk powder box 10 is correspondingly set to be adapted to the outer wall of the connecting pipe section 231; in this way, it is more convenient to assemble the connecting pipe section 231 of the powder inlet pipe 23 and the powder outlet 11.

[0033] It should be noted that, in the present case, the powder inlet pipe 23 and the funnel cover 22 may be integrally provided, and may be fixedly assembled and connected, or may be movably connected.

[0034] under, Figure 2 , Figure 4 and Figure 6 The present embodiment proposes a preferred solution for movably connecting the powder inlet pipe 23 and the funnel cover 22: the powder inlet pipe 23 is inserted into the powder inlet port 221, and a first limiting portion 232 and a second limiting portion 233 are provided on the outer wall of the powder inlet pipe 23, the first limiting portion 232 is located above the funnel cover 22, and the second limiting portion 233 is located below the funnel cover 22; a telescopic spring 24 is sleeved on the powder inlet pipe 23, and the telescopic spring 24 is in a compressed state and is stuck between the outer surface of the funnel cover 22 and the first limiting portion 232; the second limiting portion 233 is stuck at the bottom edge of the powder inlet port 221 to prevent the powder inlet pipe 23 from being separated from the powder outlet 11 under the elastic force of the telescopic spring 24. In the movable connection scheme of this embodiment, the telescopic spring 24 elastically presses against the first limiting portion 232 of the powder inlet tube 23, so that the connecting tube section 231 of the powder inlet tube 23 is tightly clamped to the powder outlet 11 of the milk powder box 10, thereby ensuring that the outer wall of the connecting tube section 231 is tightly fitted with the inner wall of the powder outlet 11.

[0035] Further, refer to Figure 2 , Figure 4 and Figure 5In this embodiment, the powder inlet 221 is configured to be compatible with the powder inlet pipe 23, and an annular protrusion 224 compatible with the powder inlet pipe 23 is provided at the top edge of the powder inlet 221. In this way, the powder inlet 221 and the annular protrusion 224 are both in contact with the outer wall of the powder inlet pipe 23, forming a guide for the powder inlet pipe 23, so that the powder inlet pipe 23 can move along the powder inlet 221 and the annular protrusion 224 in the axial direction of the powder inlet 221.

[0036] The active connection scheme of the powder inlet pipe 23 and the funnel cover 22 of this embodiment is combined with the scheme that the pipe opening of the connecting pipe section 231 gradually decreases from its bottom end to the top end in the above embodiment; in this way, when the mixing funnel assembly 20 is disassembled, it is only necessary to pull out the funnel bracket 25 on which the mixing funnel assembly 20 is installed toward the front of the milk making machine. Because, during the withdrawal process, the outer wall of the connecting pipe section 231 will be subjected to the squeezing force generated by the powder outlet 11 toward the rear of the milk making machine. Since the outer wall of the connecting pipe section 231 is inclined, the squeezing force on the connecting pipe section 231 will generate a downward component force, which will push the connecting pipe section 231 out of the powder outlet 11, so that the connecting pipe section 231 will not hinder the disassembly of the mixing funnel assembly 20; similarly, the installation operation of the mixing funnel assembly 20 also only needs to push the funnel bracket 25 in from the front of the milk making machine.

[0037] Further, refer to Figure 2 and Figure 6 The first limiting portion 232 of the present embodiment is preferably a limiting plate arranged around the powder inlet pipe 23, and the limiting plate is arranged at the edge of the bottom end of the connecting pipe section 231. In this way, when the connecting pipe section 231 is inserted into the powder outlet 11 of the milk powder box 10, the limiting plate will be stuck on the periphery of the powder outlet 11, so that the cooperation between the connecting pipe section 231 and the powder outlet 11 is more stable.

[0038] Further, refer to Figure 2 and Figure 4 The second limiting portion 233 of this embodiment is preferably a sealing ring, the outer diameter of which is larger than the diameter of the powder inlet 221, and the sealing ring seals against the bottom edge of the powder inlet 221, so that the powder inlet pipe 23 and the powder inlet 221 are sealed. Figure 5 and Figure 6 In this embodiment, an annular receiving groove 234 is further provided at the position of the powder inlet pipe 23 corresponding to the sealing ring, and the sealing ring is stuck in the annular receiving groove 234; of course, the sealing ring can also be integrally formed on the side wall of the powder inlet pipe 23, or be arranged on the powder inlet pipe 23 in other ways.

[0039] The present invention also proposes a milk making machine, which includes a machine body, a milk powder box 10 and a making funnel assembly 20. The specific structure of the making funnel assembly 20 refers to the above embodiment. Since the milk making machine adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0040] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
