Description

TECHNICAL FIELD

[0001] The present application belongs to the field of beverage making, and in particular relates to a full-automatic milk foam whipping system and a milk foam machine. BACKGROUND

[0002] The existing milk product whipping methods mainly include semi-automatic whipping and full-automatic whipping. The semi-automatic whipping is to whip the milk product in an open container by using a handheld mixer, and the whipping degree can only be controlled by adjusting the stirring frequency. The whipping degree is different each time, and the uniformity cannot be guaranteed. The full-automatic whipping is to inject raw materials and a certain amount of air into a whipping rod with a specific stirring path according to a certain proportion, so that the raw materials are mixed and stirred in the path. A large whipping pressure is generated in the mixing and stirring process, and the performance of the pump is required to be high, which leads to high cost of the whole machine. Another full-automatic whipping is to inject high-pressure steam into the raw materials to make the milk product whip. The intervention of high-pressure steam will make the raw materials mixed with water, which affects the taste, and the delicacy cannot be controlled. In addition, a steam boiler for generating high-pressure steam needs to be set, and the equipment is also expensive.

The milk foam whipping mechanism includes a foaming device, a foaming cavity arranged in the foaming device, a steam nozzle connected with the foaming cavity, a milk inlet pipe, a milk foam nozzle, and an air inlet adjusting assembly. Steam is delivered into the foaming cavity through the steam nozzle to make the milk form delicate milk foam.

[0040] For keeping the following description of the embodiments of the present application clear and brief, detailed description of known functions and known components is omitted.

[0041] The embodiments of the present application provide a full-automatic milk foam whipping system, which can be used in a milk foam machine or a coffee machine to provide milk foam.

[0042] As shown in Figure 1 and Figure 2 , the full-automatic milk foam whipping system comprises an air inlet module 1, a delivery pump 2 and a milk foam generator 3. The air inlet module 1 has an air inlet 111 and an air outlet 112, the flow area of the air inlet 111 is smaller than that of the air outlet 112, that is, the air outlet amount of the air outlet 112 is determined by the air inlet amount of the air inlet 111. The air inlet 111 is in communication with the outside atmosphere to allow air to enter the air inlet module 1. The air inlet module 1 comprises an air inlet adjusting assembly 12, which is used to adjust the opening degree of the air inlet 111 to adjust the air inlet amount, thereby adjusting the air outlet amount of the air outlet 112. Among them, Figure 1 The air inlet 111 is not shown in the figure because it is blocked by a cover 15 (which will be described below). The opening degree of the air inlet 111 includes full opening, full closing and any opening state between full opening and full closing.

[0043] As shown in Figure 2 , the inlet of the delivery pump 2 is connected with the air outlet 112 and a milk supply pipe at the same time, the outlet of the delivery pump is connected with the milk foam generator 3, which is used to deliver the milk liquid mixed with air (hereinafter referred to as raw material) to the milk foam generator 3.

[0044] As shown in Figures 3 to 5 , the milk foam generator 3 comprises a whipping cylinder 31, a whipping component 32 arranged in the whipping cylinder 31 and a driving component 33 arranged on the whipping cylinder 31. The whipping cylinder 31 is provided with a material inlet 314 and a material outlet 315, the material inlet 314 is connected with the outlet of the delivery pump 2, which is used to allow the raw material delivered by the delivery pump 2 to enter the whipping cylinder 31. The driving component 33 is connected with the whipping component 32 to provide power for the whipping component 32, so that the whipping component 32 rotates in the whipping cylinder 31 to mix and whip the raw material entering the whipping cylinder 31 to form milk foam, which is discharged from the material outlet 315.

[0045] The full-automatic milk foam whipping system of the embodiments of the present application does not need steam, so the steam boiler can be omitted to reduce the cost. Moreover, the raw material is mixed and whipped by the whipping component 32 in the milk foam generator 3, which is a normal pressure dynamic whipping, so high pressure is not needed, the performance requirement of the delivery pump 2 is not high, further reducing the cost. In addition, the air amount entering the milk foam generator 3 can be controlled by the air inlet adjusting assembly 12 to control the fineness of the milk foam, so that the user can be provided with milk foam with different fineness to meet the needs of different milk foam product recipes.

[0046] In some embodiments, as shown in Figure 6 and Figure 7 , the air inlet module 1 further comprises an air inlet base 11, an air cavity 113 is arranged in the air inlet base 11, and the air inlet 111 and the air outlet 112 are arranged on the air inlet base 11 and communicate with the air cavity 113 respectively. The air inlet adjusting assembly 12 is arranged on the air inlet base 11 and is used to adjust the opening degree of the air inlet 111 to change the effective flow area of the air inlet 111. The shape of the air inlet 111 is not limited and can be determined according to actual conditions. For example, the shape of the air inlet 111 can be circular or strip-shaped to facilitate the air inlet adjusting assembly 12 to adjust the air inlet 111 between full opening and full closing by rotating or moving. The air outlet 112 can be provided with a connecting head 115, the connecting head 115 forms a pipeline air inlet end, and the connecting head 115 is connected with the inlet of the delivery pump 2 through the air supply pipeline 21. The ambient air enters the air cavity 113 through the air inlet 111 and enters the air supply pipeline 21 through the connecting head 115, and is finally pumped by the delivery pump 2 to the milk foam generator 3.

[0047] Continuing to combine Figure 6 and Figure 7 , the air inlet adjusting assembly 12 comprises a power component 121, a transmission mechanism, and an air inlet baffle 13. The power component 121 is connected with the transmission mechanism, the transmission mechanism is connected with the air inlet baffle 13, and the power component 121 drives the air inlet baffle 13 to move linearly or rotate through the transmission mechanism to gradually block the air inlet 111 or gradually open the air inlet 111, so as to adjust the opening degree of the air inlet 111. The air inlet adjusting assembly 12 has simple structure and is easy to realize.

[0048] For example, as shown in Figure 6 , the power component 121 adopts a motor, the transmission mechanism comprises a driving wheel 122, a driven wheel 123, a screw rod 124, and an adjusting block 125. The motor is connected with the driving wheel 122, the driving wheel 122 is engaged with the driven wheel 123, the driven wheel 123 is connected with the screw rod 124, and the adjusting block 125 is provided with a rack 1251 which is engaged with the screw rod 124. When the motor is started, the driving wheel 122 is driven to rotate, the driving wheel 122 drives the driven wheel 123 and the screw rod 124 to rotate synchronously when the driving wheel 122 rotates, and the screw rod 124 drives the adjusting block 125 to move linearly when the screw rod 124 rotates. The air inlet baffle 13 is fixed on the adjusting block 125 and moves linearly synchronously with the adjusting block 125. The driven wheel 123 is not limited to one, but can be a plurality of driven wheels which are engaged with each other in sequence.

[0049] It can be understood that the adjusting block 125 and the air inlet baffle 13 can be an integral structure. In order to ensure the fit degree of the air inlet baffle 13 and the air inlet 111, so that the air inlet baffle 13 can seal the air inlet 111, the air inlet baffle 13 is preferably made of soft material, such as silica gel and the like. In order to facilitate the processing of the tooth part to form the rack 1251 and effectively mesh with the screw rod 124, the adjusting block 125 is preferably made of hard material, such as plastic and the like.

[0050] As shown in Figure 7 and Figure 10 , the air inlet 111 is in a strip shape and is arranged on the first cavity wall 114 of the air cavity 113, and the length direction of the air inlet 111 is consistent with the moving direction of the adjusting block 125. The air inlet baffle 13 is arranged on the first cavity wall 114 and closely fits with the first cavity wall 114, and can be driven by the adjusting block 125 to move linearly along the first cavity wall 114, and the linear reciprocating movement of the air inlet baffle 13 realizes the gradual closing or opening of the air inlet 111. In this way, the control of the air intake can be conveniently realized.

[0051] As shown in Figure 7 and Figure 8 , the air inlet seat 11 is also provided with a containing cavity 14, and the containing cavity 14 is used to accommodate the transmission mechanism of the air inlet adjusting assembly 12 and the air inlet baffle 13, so as to shield and protect the air inlet adjusting assembly 12, avoid the exposure of the gear, the screw rod 124 and other components, and prolong the service life.

[0052] As shown in Figure 6 , the containing cavity 14 is located above the air cavity 113, and the containing cavity 14 protrudes from the air cavity 113 in the moving direction of the adjusting block 125, so that the containing cavity 14 forms a strip shape. The first cavity wall 114 is located between the containing cavity 14 and the air cavity 113, and forms a partition plate therebetween. The first cavity wall 114 extends along the moving direction of the adjusting block 125 to form the bottom wall of the containing cavity 14, and the air inlet baffle 13 is arranged on the bottom wall. The upper side of the containing cavity 14 is open and is provided with a cover 15, so as to cover the transmission mechanism and the air inlet baffle 13 in the containing cavity 14. The cover 15 is provided with a through hole 151 for allowing external gas to enter the containing cavity 14. The shape of the through hole 151 is not limited, as long as the flow area is larger than that of the air inlet 111, and the external gas can enter the containing cavity 14 through the through hole 151.

[0053] In some embodiments, the fully automatic milk foam whipping system further comprises a micro switch 6, which can be arranged on the inner side of the cover 15 and close to the end of the air inlet 111 away from the power component 121. When the air inlet baffle 13 completely closes the air inlet 111, the adjusting block 125 triggers the micro switch 6 to close, as shown in Figure 9When the air intake baffle 13 opens the air inlet 111, the adjusting block 125 releases the triggering of the micro switch 6, and the micro switch 6 is disconnected, see Figure 10 .

[0054] The motor can rotate in a forward direction and a reverse direction, i.e., the motor can rotate in a first direction (the first direction can be a clockwise direction or a counterclockwise direction) and can rotate in a second direction opposite to the first direction. For example, when the motor rotates in the first direction, the motor sequentially pushes the air intake baffle 13 outward through the drive wheel 122, the driven wheel 123, the screw rod 124, and the adjusting block 125, so that the air intake baffle 13 gradually moves toward the air inlet 111 and can completely close the air inlet 111, and the air intake amount of the air inlet 111 at this time is zero. When the air intake baffle 13 completely closes the air inlet 111, the adjusting block 125 triggers the micro switch 6 to be closed, see Figure 9 , and the position of the adjusting block 125 at this time is set as an initial position. The micro switch 6 is connected to the control system of the full-automatic milk foam whipping system and sends an on-off signal to the control system, so that the control system can detect whether the adjusting block 125 is in the initial position through the signal sent by the micro switch 6.

[0055] When the motor rotates in the second direction, the motor sequentially pulls the air intake baffle 13 back through the drive wheel 122, the driven wheel 123, the screw rod 124, and the adjusting block 125, so that the air intake baffle 13 gradually moves away from the air inlet 111 and gradually opens the air inlet 111, and when the air inlet 111 is completely opened, the air intake amount of the air inlet 111 is a maximum value. At the same time, the adjusting block 125 releases the triggering of the micro switch 6, and the micro switch 6 is disconnected, see Figure 10 . The position of the adjusting block 125 at this time is set as an end position. The end position of the adjusting block 125 can be customized, and a maximum stroke of the adjusting block 125 is preset in the control system. The position of the adjusting block 125 when the adjusting block 125 reaches the maximum stroke position is determined as the end position, the control system disconnects the power supply for the motor, and the motor stops rotating.

[0056] As shown in Figure 9 and Figure 10 , the end of the adjusting block 125 away from the motor is a free end, and forms a triggering end for triggering the micro switch 6. The side of the triggering end close to the micro switch 6 is provided with an inclined angle 1252, which cooperates with the micro switch 6. In this way, the front end of the triggering end can pass the air inlet 111, so that the air intake baffle 13 effectively seals the air inlet 111.

[0057] In some embodiments, as shown in Figure 6 , the full-automatic milk foam whipping system further comprises a grating 4, and the middle part of the grating 4 is fixed on the output shaft of the motor and is driven by the motor to rotate. As shown in Figure 7 andFigure 8 As shown, the middle part of the grating 4 extends to the circumference of the grating 4 in a radial direction with multiple equidistant bars 41.

[0058] Continuing to combine Figures 6 to 8 The full-automatic milk froth whipping system further comprises an optical coupling sensor 5 arranged on the air inlet seat 11 or the cover 15. The transmitting end 51 and the receiving end 52 of the optical coupling sensor 5 are respectively located on the opposite sides of the grating 4 in the direction of the output shaft of the motor. When the grating 4 rotates with the output shaft, the bars 41 can pass through between the transmitting end 51 and the receiving end 52 one by one. The optical coupling sensor 5 obtains the number of bars 41 passing through and obtains the corresponding pulse number.

[0059] Specifically, during the rotation of the grating 4, the optical coupling sensor 5 detects that one bar 41 passes between the transmitting end 51 and the receiving end 52, and records a pulse number. When the adjusting block 125 moves from the initial position to the terminal position, the optical coupling sensor 5 records the corresponding total pulse number. The full-automatic milk froth whipping system controls the adjusting block 125 to be in the initial position where the air inlet baffle 13 completely closes the air inlet 111 at the beginning / end of each work. The air inlet amount of the air inlet 111 can be realized by controlling the pulse proportion. That is, when adjusting the air inlet amount of the air inlet 111, it always starts from zero air inlet amount, and then starts the motor. The specific position of the air inlet baffle 13 is determined by the ratio of the pulse number recorded by the optical coupling sensor 5 during the starting process of the motor to the total pulse number. According to the specific position of the air inlet baffle 13, the opening size of the air inlet 111 is obtained, and then the air inlet amount is determined. The specific position of the air inlet baffle 13 in the embodiment of the application is sensed by the optical coupling sensor 5 and the micro switch 6, so that the air inlet amount is automatically controlled, and the control precision is high.

[0060] In some embodiments, as shown in Figure 4 and Figure 5 The whipping component 32 is in the shape of a rod, the outer peripheral wall of the whipping component 32 is adapted to the shape of the inner peripheral wall of the whipping cylinder 31, the outer peripheral wall of the whipping component 32 is provided with first vanes 321, and the inner peripheral wall of the whipping cylinder 31 is provided with second vanes 313. By arranging the first vanes 321 and the second vanes 313, the whipping effect can be improved, and the user can obtain milk froth meeting the needs.

[0061] During the whipping process, the whipping component 32 rotates at high speed under the driving action of the driving component 33. The first vanes 321 on the outer peripheral wall of the whipping component 32 drive the raw materials in the whipping cylinder 31 to rotate in a turbine shape. The second vanes 313 on the inner peripheral wall of the whipping cylinder 31 are relatively static, which can have an impact on the bubbles in the raw materials and produce a cutting effect, so as to mix and stir the raw materials in the whipping cylinder 31. The bubbles in the raw materials can be continuously cut into small and dense bubbles. The whipped milk froth product is squeezed out of the discharge port 315, so as to realize the automatic whipping action of the milk froth.

[0062] Further, as shown in Figure 4 and Figure 5 , the first blades 321 are arranged in rows along the axial direction of the whipping component 32, the second blades 313 are arranged in rows along the axial direction of the whipping cylinder 31, and the first blades 321 and the second blades 313 are staggered in the axial direction (vertical direction in the whipping cylinder 31) of the whipping cylinder 31. The blades are thus arranged, which is better for the stirring and cutting effect on the raw materials, and can avoid interference between the two types of blades during rotation. Figure 4

[0063] In some embodiments, as shown in Figure 4 , the driving component 33 can adopt a motor, the output shaft of the motor extends into the gear box 34 and is connected with the gear set 35 in the gear box 34. The first end of the whipping component 32 is provided with a connecting shaft 322, the connecting shaft 322 is connected with the gear set 35 through the gear box 34, and the connecting shaft 322 and the box body of the gear box 34 are rotationally connected through the bearing 37. In this way, the driving component 33 can drive the rotation of the connecting shaft 322 through the gear set 35, and the connecting shaft 322 drives the rotation of the whipping component 32, so as to whip the raw materials in the whipping cylinder 31.

[0064] In order to ensure the stable rotation of the whipping component 32 in the whipping cylinder 31, the second end of the whipping component 32 is rotationally connected with the whipping cylinder 31 through the bearing 37. Specifically, as shown in Figure 4 , the whipping cylinder 31 includes a cylinder body 311, and a connecting flange 36 is fixedly arranged outside the first end of the cylinder body 311, and the connecting flange 36 is connected with the gear box 34. The second end of the cylinder body 311 is provided with a cylinder cover 312.
