Description

Technical Field

[0001] The invention relates to the technical field of milk making machine equipment, and in particular to a high-precision full-automatic milk making machine without heating. Background Art

[0002] A milk making machine is a maternal and infant device used to automatically add and stir milk powder and water into milk liquid according to a certain ratio. The milk making machines in the prior art have the following problems: 1. Most milk making machines use stirring blades to mix milk powder and water. The disadvantage of this stirring structure is that it is large in size and difficult to clean; 2. Most milk making machines in the prior art are equipped with a weighing sensor under the milk bottle, and the weighing sensor is used to detect the weight of water or milk powder added to the milk bottle. When the weight of this weighing structure reaches the set value, the water or milk powder is still on the way to the milk bottle, so the error is large; 3. The milk powder adding mechanism in the prior art is to set a powder leakage hole and a driving component that can close the powder leakage hole at the bottom of the milk powder bin. The disadvantage of this structure is that due to the accumulation of milk powder, the milk powder is not easy to fall from the powder leakage hole; 4. The milk making machine in the prior art directly discharges the prepared milk liquid into the milk bottle below, and the milk liquid will foam in the milk bottle in large quantities. Since the milk foam contains air, infants and young children are prone to flatulence after drinking the milk liquid. Summary of the invention

[0003] In view of the shortcomings of the prior art, the main purpose of the present invention is to provide a fully automatic milk making machine that can fully dissolve milk powder and is small in size and easy to clean. The second secondary purpose is to provide a milk making machine that can accurately measure the weight of milk powder. The second secondary purpose is to provide a milk making machine with low resistance and smooth powder supply. The third secondary purpose is to provide a milk making machine that can reduce milk foaming.

[0004] To achieve the above object, the present invention provides the following technical solution: a non-heating high-precision fully automatic milk making machine, comprising: A housing assembly, comprising a base and a housing disposed on the base, wherein the milk bottle is disposed on the base; A powder supply mechanism, comprising a powder storage bin with a powder pushing and feeding screw at the bottom, the powder storage bin is arranged in a receiving groove of a shell, the powder pushing and feeding screw is connected to a driving assembly, and a weighing assembly capable of weighing the entire powder supply mechanism is arranged at the bottom of the powder storage bin; A mixing and stirring mechanism, comprising a funnel-shaped mixing chamber and a mixing chamber located below the mixing chamber, wherein the mixing chamber is connected to a high-pressure water supply assembly, and the powder outlet of the powder storage chamber is correspondingly arranged above the inner wall of the mixing chamber, and the hot water in the mixing chamber is mixed with the milk powder and then falls into the mixing chamber below, and a secondary mixing chamber with a wedge-shaped bottom surface is arranged in the mixing chamber, and the milk liquid after secondary mixing falls from the mixing chamber into the feeding bottle; A control panel is electrically connected to the powder supply mechanism and the high-pressure water supply component.

[0005] Preferably, an annular flow channel is provided on the inner wall of the mixing chamber along the high-pressure water outlet of the high-pressure water supply assembly.

[0008] Preferably, the weighing assembly includes a weighing fixed plate arranged in the accommodating groove, and a sensor mounting seat and a weighing sensor are arranged on the weighing fixed plate. The two ends of the weighing sensor are connecting ends, and the two connecting ends are respectively fixedly connected to the sensor mounting seat and the bottom of the motor fixing plate.

[0009] Preferably, the high-pressure water supply assembly includes a water inlet arranged on the shell, the water inlet is connected to a water meter, a water pump and a solenoid valve in sequence through a water pipe, and the water pipe is connected to a high-pressure water outlet connected to a mixing and stirring mechanism.

[0010] Preferably, a bottle seat is provided on the base, and the bottle seat includes an inclined bottom surface for supporting the bottom of the bottle and an inclined arc surface for supporting the wall of the bottle, the inclined bottom surface is arranged perpendicular to the inclined arc surface, and when the bottle is placed on the bottle seat, the milk flowing out of the milk outlet falls from the bottle outlet onto the bottle wall.

[0011] The present invention has the following advantages over the prior art: milk powder is provided by a powder supply mechanism, and a weighing assembly arranged below the powder supply mechanism can weigh the entire powder supply mechanism, with higher precision. The secondary fusion and stirring of milk powder and water is achieved by a mixing and stirring mechanism, ensuring that the milk powder is fully dissolved, and the volume is small and easy to clean.

DETAILED DESCRIPTION

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] like Figure 1 As shown, a non-heating high-precision fully automatic milk making machine comprises: A housing assembly 1, comprising a base 11 and a housing 12 disposed on the base 11, and a milk bottle is disposed on the base 11; A powder supply mechanism 2, comprising a powder storage bin 21 with a powder pushing and feeding screw 22 at the bottom, the powder storage bin 21 is arranged in a receiving groove 121 of a housing 12, the powder pushing and feeding screw 22 is connected to a driving component 4, and a weighing component 3 capable of weighing the entire powder supply mechanism 2 is arranged at the bottom of the powder storage bin 21; A mixing and stirring mechanism 5, comprising a funnel-shaped mixing chamber 51 and a mixing chamber 52 located below the mixing chamber 51, wherein the mixing chamber 51 is connected to a high-pressure water supply assembly 6, and the powder outlet 231 of the powder storage chamber 21 is correspondingly arranged above the inner wall of the mixing chamber 51, and the hot water in the mixing chamber 51 is mixed with the milk powder and then falls into the mixing chamber 52 below, and a secondary mixing chamber 521 with a wedge-shaped bottom surface 522 is arranged in the mixing chamber 52, and the milk liquid after secondary mixing falls into the feeding bottle from the mixing chamber 52; A control panel 7 is electrically connected to the powder supply mechanism 2 and the high-pressure water supply component 6 .

[0016] The present invention is a non-heating high-precision fully automatic milk making machine, which provides milk powder through the powder supply mechanism 2. The weighing component 3 arranged below the powder supply mechanism 2 can weigh the entire powder supply mechanism 2, and its precision is higher. The secondary fusion and stirring of milk powder and water is achieved through the mixing and stirring mechanism 5, which ensures that the milk powder is fully dissolved, and its small size is easy to clean. The powder supply mechanism 2 and the high-pressure water supply component 6 are operated through the control panel 7. The high-pressure water supply component 6 in the present invention provides hot water for mixing with milk powder. The high-pressure water supply component 6 provides high-pressure water to the mixing chamber 51, and the hot water sprayed from the high-pressure water outlet 65 mixes with the milk powder along the inner wall of the mixing chamber 51 and falls into the mixing chamber 52 below from the liquid outlet. This is the first fusion and stirring of the milk powder and the hot water. The milk flowing from the liquid outlet to the mixing chamber 52 will be stirred for the second time in the secondary mixing chamber 521. This is because the milk first drips on the wedge-shaped bottom surface 522. The dripping and flowing process of the milk on the wedge-shaped bottom surface 522 further dissolves the milk powder. This is the secondary stirring. Finally, the milk is discharged from the drainage hole.

[0017] Preferably, an annular flow channel 511 is provided on the inner wall of the mixing chamber 51 along the high-pressure water outlet 65 of the high-pressure water supply assembly 6 .

[0018] The purpose of providing the annular flow channel 511 is to allow the hot water sprayed from the high-pressure water outlet 65 to flow down along the inner wall of the stirring chamber 51 in a large range, thereby increasing the dissolution and mixing area. The shape of the stirring chamber 51 is preferably an eccentric funnel, which can increase the flow of milk and improve the degree of dissolution of milk powder.

[0019] Preferably, one end of the powder pushing and feeding screw 22 is driven to rotate by the driving assembly 4, and the powder storage bin 21 includes a powder outlet channel 211 for the powder pushing and feeding screw 22 to be placed in, and the end of the powder outlet channel 211 is clamped with a powder outlet cover 23 that can support the powder pushing and feeding screw 22, and the bottom of the powder outlet cover 23 is provided with a powder dropping hole.

[0020] The powder pushing and feeding screw 22 is a trumpet-shaped screw, with a thinner thread section in the powder storage bin 21 and a thicker thread section in the powder outlet channel 211. The advantage of this design is that when the milk powder is transported, the resistance is low when the milk powder is driven to the powder outlet channel 211 by the thinner thread section, and the process is smooth. The powder pushing and feeding screw 22 is driven to rotate by the driving component 4, and can first transport the milk powder in the powder storage bin 21 to the powder outlet channel 211, and then drop from the powder drop hole at the bottom of the powder outlet cover 23. The transportation ends when the driving component 4 stops.

[0021] Preferably, the driving assembly 4 includes a motor 41, a first bevel gear 42 fixedly connected to the output shaft of the motor 41, and a second bevel gear 43 meshingly connected to the first bevel gear 42, the second bevel gear 43 is embedded in the powder storage bin 21 through a rolling bearing 44, one end of the powder pushing and feeding screw 22 is fixedly connected to the second bevel gear 43, the motor 41 is fixedly set on the motor 41 fixing plate, and the motor 41 fixing plate is fixedly set below the powder storage bin 21.

[0022] The driving assembly 4 drives the first bevel gear 42 to rotate through the motor 41, the first bevel gear 42 drives the second bevel gear 4334 to rotate, and the second bevel gear 43 drives the powder pushing and feeding screw 22 to rotate. The whole process is stable and smooth.

[0023] Preferably, the weighing assembly 3 includes a weighing fixed plate 31 arranged in the accommodating groove 121, and a sensor mounting seat and a weighing sensor 32 are arranged on the weighing fixed plate 31. The two ends of the weighing sensor 32 are connecting ends, and the two connecting ends are respectively fixedly connected to the sensor mounting seat and the bottom of the motor 41 fixing plate.

[0024] The entire powder storage bin 21 is supported by a weighing sensor 32, and the powder storage bin 21 is equivalent to being suspended in the receiving groove 121 of the milk making machine housing 12. Milk powder is placed in the powder storage bin 21, and the weighing sensor 32 weighs the weight of the powder storage bin 21 and the milk powder in real time. When milk powder needs to be prepared, the milk powder is discharged from the powder storage bin 21, so that the value weighed by the weighing sensor 32 will change, and the reduced amount is the precise weight of the discharged milk powder.

[0025] Preferably, the high-pressure water supply assembly 6 includes a water inlet 61 arranged on the shell 12, and the water inlet 61 is connected to a water meter 62, a water pump 63 and a solenoid valve 64 in sequence through a water pipe, and the water pipe is connected to a high-pressure water outlet 65 connected to the mixing and stirring mechanism 5.

[0026] The water meter 62 can control the supply amount of hot water with high accuracy, and the cooperation of the water pump 63 and the electromagnetic valve 64 can realize high-pressure water supply.

[0027] Preferably, a bottle seat 8 is provided on the base 11, and the bottle seat 8 includes an inclined bottom surface 81 for supporting the bottom of the bottle and an inclined arc surface 82 for supporting the wall of the bottle, and the inclined bottom surface 81 is vertically arranged to the inclined arc surface 82. When the bottle is placed on the bottle seat 8, the milk flowing out from the milk outlet falls from the bottle outlet onto the bottle wall.

[0028] By adding the setting of the milk bottle seat 8, the milk bottle is tilted when receiving milk. When the milk bottle is placed on the milk bottle seat 8, the milk flowing out from the milk outlet falls from the milk bottle mouth to the milk bottle wall. This structure is the same as the principle that pouring beer along the wall of a cup can reduce the generation of foam. The milk first contacts the wall of the milk bottle, and then flows down along the inner wall of the milk bottle, which can effectively reduce the phenomenon of milk foaming. The milk bottle seat 8 in this solution can be fixedly connected to the base 11, for example, by a plastic bolt, or it can be a separate design.

[0029] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
