Description

Technical Field

[0001] The utility model relates to the technical field of milk mixers, in particular to a milk powder brewing device. Background Art

[0002] A milk mixer is a device that can output hot water and milk powder in a mixing chamber, and the milk powder is mixed with hot water in the mixing chamber to achieve the milk brewing operation. When the existing milk mixers are modulating, the mixing solubility of the milk powder and water is not good, and there are often milk powder lumps remaining in the brewing funnel and the milk bottle. The milk powder and water mixture brewed is in a discrete state, resulting in the milk flowing out not in a water column shape.

[0003] Chinese Patent CN207654031U discloses a mixer of a milk mixer, which includes a cup body and a cup cover. The cup cover covers the upper opening of the cup body. One side of the cup body is provided with a water inlet, the cup body is provided with a water outlet, and a stirrer that can rotate freely is arranged in the cup body, and the outlet end of the water inlet faces the stirrer. This technical solution drives the stirrer to rotate by the high-pressure water pumped in through the water inlet, so that the mixer has a good mixing and stirring effect.

[0004] However, both this mixer and the existing milk mixers have the problem of milk powder caking at the powder inlet. The reason is that after the hot water flushes into the mixer, the water vapor cannot be discharged from the lower brewing port, and the humidity in the mixer gradually rises, resulting in the powder inlet being wet. The milk powder will adsorb at the inlet when passing through it, leading to caking, which makes the input amount of milk powder inaccurate. Over time, the caked milk powder will also become moldy and deteriorate. Therefore, the existing technology still needs to be improved and developed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a milk powder brewing device with reasonable structure and good brewing effect in view of the defects and deficiencies of the existing technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A milk powder brewing device according to the present utility model includes a mixer and a bin cover. The mixer has a mixing chamber, and the bin cover seals the upper port of the mixer. A powder inlet and an exhaust port are provided on the bin cover, and the powder inlet and the exhaust port are respectively communicated with the mixing chamber. A rotatable turbine is provided in the mixing chamber, and a water injection pipe is provided on the mixer. The water injection pipe is communicated with the mixing chamber and the outlet end of the water injection pipe faces the turbine. The powder inlet is used to connect to a powder box, and the powder box intermittently feeds milk powder into the mixing chamber. The water injection pipe is connected to a water tank, and the water tank continuously injects water into the mixing chamber. The water flow impacts the turbine to make it rotate in the mixing chamber. The rotation of the turbine can disperse the milk powder fed into the mixing chamber, and at the same time form a vortex in the mixing chamber, so as to fully mix the milk powder and water evenly. Further, the water vapor generated by the hot water for brewing milk powder can be discharged from the exhaust port to prevent the milk powder from caking due to moisture at the powder inlet.

[0008] According to the above solution, a centering terminal is provided in the mixing chamber, and the turbine is rotatably installed on the centering terminal. The centering terminal is fixedly connected to the mixer or the bin cover. It can be understood that the outer shape of the mixer can be a non-circular structure, but the mixing chamber is usually a circular cavity to enable the turbine to rotate in the mixing chamber. Of course, the turbine and the mixing chamber are concentrically arranged, and the centering terminal is arranged at the center of the two. The turbine is installed on the centering terminal through a bearing, and the centering terminal is fixedly connected to the mixer or the bin cover, so that the turbine can rotate in the mixing chamber. The centering terminal can be installed on the bin cover or the mixer according to requirements.

[0009] According to the above solution, a guiding seat is provided on the mixer. The guiding seat has a first side wall and a second side wall, and the first side wall and the second side wall are arranged in an "L" shape. The first side wall is tangent to the inner wall of the mixing chamber, and the water injection pipe is fixedly connected to the second side wall, so that the outlet end of the water injection pipe faces parallel to the first side wall. The guiding seat protrudes from the outer wall of the mixer. The guiding seat establishes a second side wall on the mixer to install the water injection pipe, thereby controlling the outlet direction of the water injection pipe. For example, the first side wall is tangent to the outer edge of the mixing chamber, so that the first side wall can guide and control the direction of the water flow, and the water flow sprayed out by the water injection pipe can better drive the turbine to rotate.

[0010] According to the above solution, a funnel structure is provided at the lower part of the mixer. The lower end of the funnel structure is provided with a liquid outlet, and the mixing chamber, the inner cavity of the funnel structure and the liquid outlet are sequentially communicated. The water flow sprayed into the mixing chamber from the water injection pipe is driven by the turbine to form a vortex, and the mixed liquid of water and milk powder flows out from the liquid outlet along the inner cavity of the funnel structure. After the vortex is rectified by the funnel structure, a downward columnar fluid can be formed at the liquid outlet to avoid splashing at the liquid outlet.

[0011] According to the above solution, an identification block is provided on the bin cover. The identification block is matched and installed on the guiding seat. The exhaust interface and the powder discharging interface on the bin cover need to be arranged in alignment to connect the powder box and the exhaust pipe. The matching of the identification block and the guiding seat determines the installation direction of the bin cover.

[0012] According to the above solution, a nested ring is provided on the bottom surface of the bin cover. The nested ring is arranged to fit the inner wall of the mixing chamber. Specifically, the diameter of the upper port of the mixer is larger than the inner diameter of the mixing chamber, thus forming a step between the two. The bin cover is sealed on the step, and the nested ring passes through the mixing chamber, which can make the connection between the bin cover and the mixer more stable.

[0013] According to the above solution, a push rod is provided on the outer wall of the nested ring, and a switch hole is provided on the side wall of the mixer. The push rod passes through the switch hole to connect the bin cover and the mixer in a cooperative manner. When the push rod is inserted into the switch hole, it can prevent the bin cover from falling off the mixer when disassembling and cleaning the mixer. The cooperative setting of the push rod and the switch hole is used to establish a locking relationship between the bin cover and the mixer. Of course, it can also be replaced by other conventional structures.

[0014] According to the above solution, the present utility model further includes a powder box, a water tank, a water pump and an exhaust pipe. The water tank, the water pump and the water injection pipe are sequentially connected through pipelines. The powder outlet of the powder box is paired and connected with the powder discharging interface, and the exhaust pipe is connected to the exhaust interface. The water pump and the water tank form a water supply assembly. The water pump pressurizes the water in the water tank and injects it into the mixing chamber. Of course, a heating device should be provided between the water tank and the water pump to provide hot water for the mixing chamber.

[0015] In a milk powder brewing device of the present utility model, milk powder is intermittently fed into the mixing chamber from the powder discharging interface. At the same time, water flushes into the mixing chamber from the water injection pipe. The water flow drives the turbine to disperse the milk powder and forms a vortex in the mixing chamber to fully stir the milk powder. The hot steam during the brewing process is discharged from the exhaust interface, avoiding the situation of milk powder getting damp and caking at the powder discharging interface.

[0020] The technical solution of the present utility model will be described below in conjunction with the drawings and embodiments.

[0021] As Figure 1-2 shown, a milk powder brewing device of the present utility model includes a mixer 1 and a bin cover 2. The mixer 1 has a mixing chamber 11. The bin cover 2 covers the upper port of the mixer 1. A powder discharge interface 21 and an exhaust interface 22 are provided on the bin cover 2. The powder discharge interface 21 and the exhaust interface 22 are respectively communicated with the mixing chamber 11. A rotatable turbine 12 is provided in the mixing chamber 11. A water injection pipe 13 is provided on the mixer 1. The water injection pipe 13 is communicated with the mixing chamber 11 and the outlet end of the water injection pipe 13 faces the turbine 12.

The water injection pipe 13 is connected to the water tank 4, and the water tank 4 continuously injects water into the mixing chamber 11. The water flow impacts the turbine 12 to make it rotate in the mixing chamber 11. The rotation of the turbine 12 can disperse the milk powder input into the mixing chamber 11, and at the same time form a vortex in the mixing chamber 11, so as to make the milk powder and water fully mixed and uniform. Further, the water vapor generated by the hot water for brewing milk powder can be discharged from the exhaust interface 22 to prevent the milk powder from caking due to moisture at the powder discharge interface 21.

[0022] A centering terminal 14 is provided in the mixing chamber 11. The turbine 12 is rotatably installed on the centering terminal 14, and the centering terminal 14 is fixedly connected to the mixer 1 or the bin cover 2. It can be understood that the outer shape of the mixer 1 can be a non-circular structure, but the mixing chamber 11 is usually a circular cavity, so that the turbine 12 can rotate in the mixing chamber 11. Of course, the turbine 12 and the mixing chamber 11 are concentrically arranged, and the centering terminal 14 is arranged at the center of the two. The turbine 12 is installed on the centering terminal 14 through a bearing, and the centering terminal 14 is fixedly connected to the mixer 1 or the bin cover 2, so that the turbine 12 can rotate in the mixing chamber 11. The centering terminal 14 can be installed on the bin cover 2 or the mixer 1 according to requirements.

[0023] The mixer 1 is provided with a guiding seat 15. The guiding seat 15 has a first side wall 151 and a second side wall 152, and the first side wall 151 and the second side wall 152 are arranged in an "L" shape; the first side wall 151 is tangent to the inner wall of the mixing chamber 11, and the water injection pipe 13 is fixedly connected to the second side wall 152, so that the outlet end of the water injection pipe 13 faces parallel to the first side wall 151.

The guiding seat 15 establishes a second side wall 152 on the mixer 1 to install the water injection pipe 13, thereby controlling the orientation of the water outlet of the water injection pipe 13. For example, the first side wall 151 is tangent to the outer edge of the mixing chamber 11, so that the first side wall 151 can guide and control the direction of the water flow, making the water flow sprayed from the water injection pipe 13 better drive the turbine 12 to rotate.

[0024] A funnel structure 16 is provided at the lower part of the mixer 1. The lower end of the funnel structure 16 is provided with a liquid outlet 161.

The water flow sprayed into the mixing chamber 11 from the water injection pipe 13 is driven by the turbine 12 to form a vortex. The mixture of water and milk powder flows out from the liquid outlet 161 along the inner cavity of the funnel structure 16. After the vortex is rectified by the funnel structure 16, a downward columnar fluid can be formed at the liquid outlet 161, avoiding the splashing phenomenon at the liquid outlet 161.

[0025] An identification block 23 is provided on the bin cover 2. The identification block 23 is matched with and covers the guiding seat 15.

The matching of the identification block 23 and the guiding seat 15 determines the installation direction of the bin cover 2.

[0026] A nested ring 24 is provided on the bottom surface of the bin cover 2. The nested ring 24 is arranged to fit the inner wall of the mixing chamber 11. Specifically, the diameter of the upper port of the mixer 1 is larger than the inner diameter of the mixing chamber 11, so as to form a step 110 therebetween. The bin cover 2 covers the step 110, and the nested ring 24 penetrates into the mixing chamber 11, which can make the connection between the bin cover 2 and the mixer 1 more stable.

[0027] A push rod 25 is provided on the outer wall of the nested ring 24, and a switch hole 17 is provided on the side wall of the mixer 1. The push rod 25 penetrates through the switch hole 17 to connect the bin cover 2 and the mixer 1 in cooperation. When the push rod 25 is inserted into the switch hole 17, it can prevent the bin cover 2 from falling off the mixer 1 when the mixer 1 is disassembled and cleaned. The cooperation setting of the push rod 25 and the switch hole 17 is used to establish a locking relationship between the bin cover 2 and the mixer 1, and of course, it can also be replaced by other conventional structures.
