Description

Technical Field

[0001] The present invention relates to the technical field of beverage preparation devices, and in particular to a beverage blending machine. Background Art

[0002] Newborns usually need to be fed multiple times at night, and feeding often requires preparing milk powder. This process includes taking out a certain amount of milk powder and putting it into the bottle, adding hot water to the bottle, and then shaking it repeatedly to mix the milk powder and water, and finally feeding it to the baby. For mothers who already lack sleep, this series of actions seems very cumbersome and time-consuming. Sometimes, in order to prepare milk powder for the baby, the mother needs to get up from the bed. After all this, it is difficult to fall asleep. Therefore, it is very necessary to use a milk powder mixing machine.

[0003] Currently, there are milk powder mixing machines on the market, which are equipped with multiple independent milk powder bins, each of which is used to hold a fixed amount of milk powder, thereby achieving multiple and quantitative milk mixing.

[0004] After searching, Chinese invention patent CN218552085U discloses a milk powder mixer, in which milk powder is pre-added into different chambers in a powder box assembly, and then the inner shell is driven by a driving member to rotate in the outer shell, so that the blocking member used to block the powder outlet is pushed open by the protrusion, and when the powder outlet is rotated to be aligned with the outlet, the milk powder placed in the chamber enters the milk bottle through the powder outlet and the outlet, so that the amount of milk powder can be called up once, and then the water in the water tank is introduced into the milk bottle through a water pump, thereby completing the automatic brewing of the milk powder.

[0005] However, the above-mentioned milk powder mixing machine has the following problems during use:

[0006] 1. The milk powder in the chamber often cannot fall into the bottle completely, and some of the milk powder still remains on the inner wall of the chamber, resulting in waste of milk powder and insufficient amount of milk powder in a single dose;

[0007] 2. The residual milk powder will get damp and clump or even deteriorate. During use, frequent opening of the lid to add milk powder due to insufficient milk powder at a time will more easily cause the milk powder to get damp and clump or even deteriorate, affecting the taste of the milk powder and even endangering the baby's health;

[0008] 3. The existing beverage dispensing machine lacks a bottle position clamping mechanism and a bottle position adjustment mechanism, and cannot adjust the height of the bottle. During the falling process, the milk powder is easy to fall outside the bottle, resulting in a waste of milk powder. It is also not suitable for bottles of various sizes, and it is inconvenient to take and put the bottle.

[0009] 4. The milk powder in each independent chamber needs to fall into the container through a common discharge port. The common discharge port is prone to residual milk powder, which is difficult to clean. The residual milk powder will be damp, agglomerated, or even deteriorate.

[0010] 5. It adopts a double-layer structure with an additional bottom cover at the bottom, which makes the structure complicated;

[0011] 6. The chamber and the cover are non-transparent, and the amount of milk powder in the silo and the feeding situation of milk powder cannot be observed from the outside. If powder is stuck or accumulated, the proportion and concentration of milk powder will not meet the standards. This will lead to malnutrition of infants in the long run and affect their growth. Summary of the invention

[0012] The object of the present invention is to provide a beverage mixing machine to solve the problem in the prior art that the height position of the mixing vessel cannot be adjusted due to the lack of a height adjustment mechanism for the mixing vessel position, resulting in the powder falling outside the milk bottle during the falling process, causing waste of powder.

The powder delivery device is used to deliver powder to the mixing vessel 31 and automatically drain water, and the powder mixing device 22 can not only mix the powder and water, but also lift and lower the mixing vessel 31 to adjust the height position of the mixing vessel 31.

[0098] Several silos are separately arranged, and a first drop opening is arranged at the bottom of each silo. The powder material directly falls into the brewing vessel through the first drop opening, which greatly reduces the possibility of blockage and prevents powder material from accumulating. Each independent silo can be cleaned separately, which is convenient and hygienic.

[0099] like Figure 2 , Figure 3 and Fig.25 As shown, in an embodiment of the present invention, the powder delivery device includes a plurality of silos 2 arranged on a machine body 1, the silos 2 are provided with a first drop opening 3 for allowing the powder in the silos to fall into a brewing vessel 31, a silo door 4 that can be opened and closed is installed at the first drop opening 3 of the silo 2, and a door opening device for opening the silo door 4 is provided on the machine body 1.

[0100] like Figure 3 As shown, in an embodiment of the present invention, the powder delivery device includes a loading platform 6 rotatably mounted on the body 1, and the silo 2 is arranged on the loading platform 6 and two or more silos are arranged around the rotation center of the loading platform 6. In this embodiment, each silo 2 is separately filled with powder, which is convenient for controlling the amount of powder prepared at a single time, and convenient for observing whether there is any powder residue in the silo 2, so as to prevent the waste of powder. At the same time, since the powder can be placed in the silo in a predetermined amount in advance, the user does not need to temporarily take the powder, nor does he need to place the powder in the silo in advance, which brings great convenience to the user. Multiple silos 2 can be placed on the loading platform 6, so that multiple portions of powder can be placed in a predetermined amount in advance, which is particularly suitable for application scenarios where milk powder needs to be prepared multiple times at night.

[0101] Furthermore, a loading platform belt rotating mechanism 61 for driving the loading platform 6 to rotate is connected to the bottom end of the loading platform 6, and the loading platform belt rotating mechanism 61 is installed on the machine body 1. A silo mounting portion 7 is provided on the loading platform 6 corresponding to the silo 2, and the silo 2 is arranged at the silo mounting portion 7. When the loading platform 6 drives the silo 2 to rotate to a preset position above the brewing vessel 31 (directly above the entrance of the brewing vessel 31), the door opening device opens the silo door 4 of the silo 2 to the preset position (directly above the entrance of the brewing vessel 31), and the powdered material can fall into the brewing vessel 31 through the first drop port 3.

[0102] Among them, a machine bin 5 is provided on the top of the machine body 1, and a machine body cover is provided on the machine bin 5. The machine bin 5 is used to accommodate the material bin 2, the loading platform 6 and the loading platform belt rotation mechanism 61. The material bin mounting portion 7 is used to fix the material bin 2, and the loading platform belt rotation mechanism 61 delivers the material bin 2 filled with material powder to the top of the entrance of the brewing vessel 31 for feeding. After the feeding is completed, the loading platform belt rotation mechanism 61 takes the empty material bin 2 away from the top of the entrance of the brewing vessel 31 to carry out the next round of feeding operation. In this embodiment, the material powder feeding device can accurately control the material bin 2 to open the bin door 4 when it is located just above the entrance of the brewing vessel 31, so as to prevent the material powder in the material bin 2 from spilling outside the brewing vessel 31, thereby preventing the material powder from being wasted.

[0103] like Figure 6 As shown, in the embodiment of the present invention, the powder delivery device can also adopt such a structural form: the powder delivery device includes a storage bin 51 arranged on the top of the machine body 1, a powder dispensing mechanism is arranged in the storage bin 51, a second drop opening 52 is arranged at the bottom of the storage bin 51 corresponding to the brewing vessel 31, and the powder dispensing mechanism is used to drop a certain amount of powder into the brewing vessel 31 through the second drop opening 52. With this design, the integrated storage bin 51 is used to store powder, and the powder can directly drop into the brewing vessel 31 through the second drop opening 52, which is simple in structure and easy to use.

[0104] In this embodiment, the powder delivery device is used in conjunction with the height adjustment device in the powder mixing device 22. The height position of the brewing vessel 31 is adjusted by the height adjustment device so that the entrance of the brewing vessel 31 is closer to the second drop port 52. This can effectively prevent the powder from falling outside the brewing vessel 31 during the falling process, thereby preventing the powder from being wasted and achieving a better use effect.

[0105] like Figure 7 As shown, in the embodiment of the present invention, the powder delivery device can also adopt such a structural form: the powder delivery device includes a storage bin 51 arranged on the top of the machine body 1, a powder dispensing mechanism is arranged in the storage bin 51, a second drop opening 52 is arranged at the bottom of the storage bin 51 corresponding to the brewing vessel 31, and the powder dispensing mechanism is used to control a certain amount of powder to fall into the brewing vessel 31 through the second drop opening 52. The second drop opening 52 is integrally or detachably installed with a bin 2, and the bin 2 is directly opposite to the brewing vessel 31, and the powder delivery device is used to control a certain amount of powder to fall into the bin 2 through the second drop opening 52.

[0106] With this design, the storage bin 51 is used to store powder. The powder can first fall into the bin through the second drop port 52 and then fall into the bin 2. The bin 2 can assist the powder to fall into the brewing vessel 31 to prevent the powder from floating outside the brewing vessel 31 during the falling process. The structure is simple and easy to use.

[0107] In this embodiment, the powder delivery device is used in conjunction with the height adjustment device in the powder mixing device 22. The height position of the brewing vessel 31 is adjusted by the height adjustment device so that the entrance of the brewing vessel 31 is closer to the second drop port 52. This can effectively prevent the powder from falling outside the brewing vessel 31 during the falling process, thereby preventing the powder from being wasted and achieving a better use effect.

[0108] In an embodiment of the present invention, the powder mixing mechanism includes a rotating powder dropping portion 62 rotatably installed in the storage bin 51, and powder is contained in the rotating powder dropping portion 62. A discharge port is provided at the bottom of the rotating powder dropping portion 62 corresponding to the second discharge port 52. When the second discharge port 52 or the silo 2 rotates to a preset position (directly above the entrance of the brewing vessel 31), the powder in the storage bin 51 passes through the discharge port and the second discharge port 52 and falls into the brewing vessel 31 or the silo 2.

[0109] Furthermore, the rotating powder dropping part 62 can be a rotating disc or a rotating bracket. The rotating powder dropping part 6 can be set as a cabin, or can include multiple independently set cabins. The size of each cabin can be the same or different, and a preset amount of powder is placed in the cabin.

[0110] Among them, when the second drop port 52 rotates to a preset position (directly above the entrance of the brewing vessel 31), the rotating powder dropping part 62 rotates until the discharge port and the second drop port 52 completely or partially overlap, and the powder in the storage bin 51 falls into the brewing vessel 31 or the silo 2 through the discharge port and the second drop port 52 in turn.

[0111] like Figure 3 , Figure 4 and Figure 5 As shown, in an embodiment of the present invention, a feed port for loading powder into the silo 2 is also provided at the top of the silo 2, and a sealing cover is provided at the feed port. The powder in the silo 2 is sealed and preserved by the sealing cover and the silo door 4 to prevent the powder from deteriorating due to moisture.

[0112] In an embodiment of the present invention, the silo 2 may be fixedly mounted on the loading platform 6 in an integrated manner, and the silo 2 and the loading platform 6 may be removed simultaneously for cleaning or maintenance.

[0113] In the embodiment of the present invention, the silo 2 may also be detachably mounted on the stage 6, and each silo 2 may be individually removed for cleaning or maintenance.

[0114] The silo 2 may be in the shape of a funnel, a straight cylinder or an inverted funnel, which is not limited here.

[0115] In an embodiment of the present invention, the bin door 4 is installed at the first drop-out port 3 in an integral or detachable manner, and the bin door 4 remains closed before the silo 2 reaches a preset position (directly above the entrance of the brewing vessel 31); when the silo 2 reaches the preset position (directly above the entrance of the brewing vessel 31), the door opening device opens the bin door 4 by directly acting on the bin door 4, or the door opening device opens the bin door 4 by acting on the bin door locking device.

[0116] When the door opening device opens the warehouse door 4 by directly acting on the warehouse door 4, the warehouse door 4 is arranged at the first drop-out port 3 in a horizontal swinging, horizontal sliding or hinged manner, and an elastic member (not shown in the drawings) is arranged between the warehouse door 4 and the silo 2 for maintaining the warehouse door 4 closed, such as a coil spring, a flat spring, an elastic rope, a torsion spring, etc., which is not limited here.

[0117] With such a design, the bin door 4 can be installed at the first material drop port 3 in a normally closed manner. Before the silo 2 reaches the preset position (directly above the entrance of the brewing vessel 31), the bin door 4 remains closed; when the silo 2 completes the powder delivery and moves away from the preset position (directly above the entrance of the brewing vessel 31), the door opening device returns to the state before acting on the bin door 4, and the bin door 4 returns to the closed state under the action of the elastic member, thereby achieving the normally closed state of the bin door 4.

[0118] Of course, the door opening device can be a motor directly connected to the warehouse door 4, and the motor can be a rotary motor or a linear motor, which directly controls the opening or closing of the warehouse door 4.

[0119] Before the silo 2 reaches the preset position (directly above the entrance of the brewing vessel 31), the motor controls the silo door 4 to remain closed; when the silo 2 reaches the preset position (directly above the entrance of the brewing vessel 31), the motor controls the silo door 4 to swing horizontally or slide horizontally or rotate along the hinge axis, thereby opening the silo door 4; after the silo 2 completes the feeding of the material powder and moves away from the preset position (directly above the entrance of the brewing vessel 31), the motor controls the silo door 4 to swing horizontally or slide horizontally or rotate in the opposite direction along the hinge axis, thereby achieving the normal closure of the silo door 4.

[0120] When the door opening device acts on the door locking device to open the door 4, the door 4 is hinged at the first drop port 3 and remains free to open and close. Before the silo 2 reaches the preset position (just above the entrance of the brewing vessel 31), the door 4 remains closed under the action of the door locking device; when the silo 2 reaches the preset position (just above the entrance of the brewing vessel 31), the door opening device acts on the door locking device, the door locking device releases the door 4, and the door 4 opens under its own gravity; after the silo 2 completes the feeding of the powder and moves away from the preset position (just above the entrance of the brewing vessel 31), the door 4 remains open.

[0121] Among them, Fig.24 As shown, in the first embodiment of the door locking device disclosed in the present invention, the door locking device includes a swing arm 14 hinged on the silo 2, the hinge point of the swing arm 14 is located in the middle, the bottom end of the swing arm 14 is provided with a hook 15, the hook 15 is used to hook the free end of the silo 4 to keep the silo 4 in a closed state, and an elastic member (not shown in the drawings) for maintaining the hook 15 hooking the free end of the silo 4 is provided between the swing arm 14 and the side wall of the silo 2, such as a coil spring, an elastic rope, etc., which is not limited here. When the upper end of the swing arm 14 is pressed, the hook 15 is separated from the silo 4 so that the silo 4 is opened.

[0122] like Fig.25 As shown, in the second embodiment of the door locking device disclosed in the present invention, the door locking device includes a swing arm 14 hinged on the silo 2, the hinge point of the swing arm 14 is located at the top thereof, and a hook 15 is provided at the bottom end of the swing arm 14, and the hook 15 is used to hook the free end of the silo 4 to keep the silo 4 in a closed state, and an elastic member (not shown in the drawings) is provided between the swing arm 14 and the side wall of the silo 2 to maintain the hook 15 hooking the free end of the silo 4, such as a coil spring, an elastic rope, etc., which is not limited here. When the middle part of the swing arm 14 is pressed, the hook 15 is separated from the silo 4 so that the silo 4 is opened.

[0123] like Fig.26As shown, in the third embodiment of the door locking device disclosed in the present invention, the door locking device includes a push block 101 slidably disposed on the silo 2, a hook 15 is disposed at the bottom end of the push block 101, the hook 15 is used to hook the free end of the silo 4 to keep the silo 4 in a closed state, and an elastic member such as a coil spring, an elastic rope, etc. is disposed between the push block 101 and the silo 2 to maintain the hook 15 hooking the free end of the silo 4, which is not limited here. When the top of the push block 101 is pressed, the push block 101 drives the hook 15 to move downward, and the hook 15 is separated from the silo 4 so that the silo 4 is opened.

[0124] In some embodiments of the present invention, various implementations of the door opening device are disclosed:

[0125] like Figure 3 , Figure 24 to Figure 26 As shown, in the first embodiment of the door opening device disclosed in the present invention, the door opening device opens the bin door 4 by acting on the bin door locking device, and the door opening device includes a pushing block 10 installed on the body 1. When the loading platform 6 drives the silo 2 to rotate to a preset position above the brewing vessel 31 (directly above the entrance of the brewing vessel 31), the pushing block 10 presses the bin door locking device (the upper end of the swing arm 14 or the middle of the swing arm 14 or the top of the pressing block 101) to disengage the hook 15 from the bin door 4, thereby opening the bin door 4.

[0126] Furthermore, a first protrusion can be provided on the pushing block 10, and a second protrusion can be provided on the door locking device corresponding to the first protrusion. When the loading platform 6 drives the silo 2 to rotate to a preset position above the brewing vessel 31, the first protrusion on the pushing block 10 presses against the second protrusion on the door locking device (the upper end of the swing arm 14 or the middle of the swing arm 14 or the top of the pressing block 101) to disengage the hook 15 from the door 4, thereby opening the door 4.

[0127] The first embodiment of the door opening device has a simple structure. The bin door 4 will only open when the material bin 2 reaches directly above the entrance of the brewing vessel 31, thereby preventing the bin door 4 from opening too early and causing the material powder to spill out.

[0128] like Figure 4As shown, in the second embodiment of the door opening device disclosed in the present invention, the door opening device opens the door 4 by acting on the door locking device. The door opening device includes a push rod 11 slidably arranged on the body 1 and a cam 111 arranged on the loading platform 6. The cam 111 rotates with the loading platform 6. The larger end of the cam 111 acts on the inner end of the push rod 11. The outer end of the push rod 11 faces the door locking device. When the loading platform 6 drives the silo 2 to rotate to the preset position above the brewing vessel 31, the cam 111 pushes the outer end of the push rod 11 to press the door locking device (the upper end of the swing arm 14 or the middle of the swing arm 14 or the top of the push block 101) to disengage the hook 15 from the door 4 so that the door 4 is opened. Of course, a reset spring that retracts the push rod 11 inward can also be arranged on the loading platform 8, which has a better use effect.

[0129] The second embodiment of the door opening device has a simple structure. The cam 111 is driven to rotate by the loading platform 6. The bin door 4 will not open until the material bin 2 reaches directly above the brewing vessel 31, thereby preventing the bin door 4 from opening prematurely and causing the material powder to spill out. At the same time, the use of electrical components is reduced, thereby reducing the failure rate.

[0130] like Figure 5 As shown, in the third embodiment of the door opening device disclosed in the present invention, the door opening device opens the door 4 by acting on the door locking device, and the door opening device includes a power component 12 installed on the body 1 and capable of outputting linear motion. When the loading platform 6 drives the material bin 2 to rotate to a preset position above the brewing vessel 31, the power output end of the power component 12 extends out to press the door locking device (the upper end of the swing arm 14 or the middle of the swing arm 14 or the top of the push block 101) to trigger the door 4 to open. The power component 12 can be a linear motor, an electromagnet, etc.

[0131] The third embodiment of the door opening device has a simple structure. The power component 12 presses the door locking device (the upper end of the swing arm 14 or the middle of the swing arm 14 or the top of the push block 101) to trigger the door 4 to open. It is simple, convenient and easy to control.

[0132] like Fig. 27 As shown, in the fourth embodiment of the door opening device disclosed in the present invention, the door opening device opens the bin door 4 by directly acting on the bin door 4, and the bin door 4 is arranged at the first drop-out port 3 in a horizontal swinging manner, and the door opening device includes a pushing block 10 installed on the body 1. When the loading platform 6 drives the silo 2 to rotate to a preset position above the brewing vessel 31 (directly above the brewing vessel 31), the pushing block 10 directly presses the bin door 4 to make the bin door 4 swing along the swing center axis so that the bin door 4 is opened, reducing the use of components, making the structure simpler, and making maintenance more convenient and more efficient.

[0133] In the fifth embodiment of the door opening device disclosed in the present invention, the door opening device opens the bin door 4 by directly acting on the bin door 4, and the bin door 4 is arranged at the first drop-out port 3 in a horizontal swinging manner. The door opening device includes a push rod 11 slidably arranged on the body 1 and a cam 111 arranged on the loading platform 6. The cam 111 rotates with the loading platform 6. The larger end of the cam 111 acts on the inner end of the push rod 11, and the outer end of the push rod 11 faces the bin door 4. When the loading platform 6 drives the silo 2 to rotate to a preset position above the brewing vessel 31, the cam 111 pushes the outer end of the push rod 11 to press the bin door 4, so that the bin door 4 swings along the swing center axis to open the bin door 4, reducing the use of components, making the structure simpler, and convenient for maintenance and more efficient.

[0134] In the sixth embodiment of the door opening device disclosed in the present invention, the door opening device opens the bin door 4 by directly acting on the bin door 4, and the bin door 4 is arranged at the first drop opening 3 in a horizontal swinging manner. The door opening device includes a power component 12 installed on the body 1 and capable of outputting linear motion. When the loading platform 6 drives the bin 2 to rotate to a preset position above the brewing vessel 31, the power output end of the power component 12 extends out to press the bin door 4, so that the bin door 4 swings along the swing center axis to open the bin door 4, reducing the use of components, making the structure simpler, and convenient to maintain and more efficient. The power component 12 can be a linear motor, an electromagnet, etc.

[0135] like Fig.28 As shown, in the seventh embodiment of the door opening device disclosed in the present invention, the door opening device opens the bin door 4 by directly acting on the bin door 4, and the bin door 4 is arranged at the first drop-out port 3 in a horizontal sliding manner, and the door opening device includes a pushing block 10 installed on the body 1. When the loading platform 6 drives the silo 2 to rotate to a preset position above the brewing vessel 31 (directly above the brewing vessel 31), the pushing block 10 directly presses the bin door 4 to make the bin door 4 slide along the slide rail to open the bin door 4, thereby reducing the use of components, making the structure simpler, convenient maintenance and more efficient.

[0136] In an eighth embodiment of the door opening device disclosed in the present invention, the door opening device opens the bin door 4 by directly acting on the bin door 4, and the bin door 4 is arranged at the first drop-out port 3 in a horizontal sliding manner. The door opening device includes a push rod 11 slidably arranged on the body 1 and a cam 111 arranged on the loading platform 6. The cam 111 rotates with the loading platform 6. The larger end of the cam 111 acts on the inner end of the push rod 11, and the outer end of the push rod 11 faces the bin door 4. When the loading platform 6 drives the silo 2 to rotate to a preset position above the brewing vessel 31, the cam 111 pushes the outer end of the push rod 11 to press the bin door 4, so that the bin door 4 slides along the slide rail to open the bin door 4, reducing the use of components, making the structure simpler, and making maintenance more convenient and more efficient.

[0137] In the ninth embodiment of the door opening device disclosed in the present invention, the door opening device opens the bin door 4 by directly acting on the bin door 4, and the bin door 4 is arranged at the first drop opening 3 in a horizontal sliding manner. The door opening device includes a power component 12 installed on the body 1 and capable of outputting linear motion. When the loading platform 6 drives the bin 2 to rotate to a preset position above the brewing vessel 31, the power output end of the power component 12 extends out to press the bin door 4, so that the bin door 4 slides along the slide rail to open the bin door 4, reducing the use of components, making the structure simpler, and convenient to maintain and more efficient. The power component 12 can be a linear motor, an electromagnet, etc.

By directly acting on the bin door 4, the bin door 4 is horizontally swung and opened, which has high efficiency and simple structure.

[0139] The driving motor 24 is a rotary motor. The power shaft of the driving motor 24 can be directly set as the swing shaft of the warehouse door 4 to directly drive the warehouse door 4 to open and close; the power shaft of the driving motor 24 can also be connected to the swing shaft of the warehouse door 4 through a transmission gear set to indirectly drive the warehouse door 4 to open and close, which is not limited here.

The power shaft of the driving motor 24 can be directly set as the hinge shaft of the warehouse door 4 to directly drive the warehouse door 4 to open and close; the power shaft of the driving motor 24 can also be connected to the hinge shaft of the warehouse door 4 through a transmission gear set to indirectly drive the warehouse door 4 to open and close, which is not limited here.

[0142] like Fig.31As shown, in the twelfth embodiment of the door opening device disclosed in the present invention, the door opening device opens the bin door 4 by directly acting on the bin door 4, and the bin door 4 is arranged at the first drop opening 3 in a horizontal sliding manner, and the door opening device includes a driving motor 24 arranged on the bin 2 for driving the bin door 4 to open and close. The driving motor 24 can be a linear motor or an electromagnet. By directly acting on the bin door 4, the bin door 4 slides horizontally to open, which has high efficiency and simple structure.

[0143] Among them, the power shaft of the driving motor 24 can be directly connected to the warehouse door 4, directly driving the warehouse door 4 to slide horizontally to achieve opening and closing; the power shaft of the driving motor 24 can also be indirectly connected to the warehouse door 4 through a transmission lever to achieve opening and closing of the warehouse door 4, so as to reduce the stroke of the driving motor 24, save space, and be more compact.

[0144] In the embodiment of the present invention, the powder delivery device has the function of automatically delivering water into the brewing vessel 31. Four implementation methods for realizing the automatic water delivery function are given below.

[0145] like Figure 8 and Fig. 9 As shown, in the first embodiment of realizing the automatic water discharge function disclosed in the present invention, a water outlet pipe 17 for connecting with a water supply device is installed on the machine body 1, and the water outlet pipe 17 has a water outlet 18, and the water outlet 18 is used to discharge water into the brewing vessel 31 through it. The water outlet pipe section 19 where the water outlet 18 is located is located below the material bin 2 or the material storage bin 51, and the water outlet pipe section 19 is installed on the machine body 1 in a manner that it can swing left and right. The machine body 1 is provided with a first power device for driving the water outlet pipe section 19 to swing. The first power device can be a swing motor installed on the machine body 1, and other structures can also be used. The power output end of the power device is connected to the water outlet pipe section 19, thereby driving the water outlet pipe section 19 to swing. When the water outlet pipe section 19 swings to make the water outlet 18 located below the material drop port, the water outlet can discharge water into the brewing vessel. When the water outlet pipe section swings to the point where the water outlet leaves the first material drop port 3, it can avoid blocking the falling of the material powder, and at the same time prevent the material powder from falling on the water outlet pipe section 19.

[0146] When the powder in the silo 2 falls into the mixing vessel 31, the drain port 18 is located directly below the first material drop port 3 when the drain pipe section 19 swings to one side, and the drain port 18 leaves the first material drop port 3 when the drain pipe section 19 continues to swing to one side or the other. Figure 7 and Figure 8 This is the state when the water discharge pipe section 19 continues to swing to one side or the other and the water discharge port 18 leaves the first material discharge port 3 .

[0147] like Fig.10 and Fig.11As shown, in the second embodiment of realizing the automatic water discharge function disclosed in the present invention, a water outlet pipe 17 for connecting to a water supply device is installed on the body 1, and the water outlet pipe 17 has a water discharge port 18, and the water discharge port 18 is used to discharge water into the brewing vessel 31 therethrough, and a water discharge pipe section 19 where the water discharge port 18 is located is located below the silo 2 or the storage silo 51, and the water discharge pipe section 19 is slidably connected to the body 1 in a manner that it can be extended and retracted forward and backward. A second power device for driving the water discharge pipe section 19 to retract and retract is provided on the body 1, and the second power device can be a linear motor installed on the body 1, or other structures can be adopted, and the power output end of the second power device is connected to the water discharge pipe section 19, thereby driving the water discharge pipe section 19 to retract and retract.

[0148] When the powder in the silo 2 falls into the brewing vessel 31, the drain pipe section 19 extends forward to the top of the brewing vessel 31 to drain the water. After the draining is completed, the drain pipe section 19 retracts backward and the drain port 18 moves to the initial position. Fig.10 The water discharge pipe section 19 is in a state of extending forward. Fig.11 The drain pipe section 19 is in a state of being retracted backwards. Of course, this solution is also applicable to the powder delivery device with the material storage bin 51. After the drain pipe section 19 is extended, the drain port 18 can discharge water into the brewing vessel 31. After the drain pipe section 19 is retracted, it can avoid blocking the falling of the powder and prevent the powder from falling onto the drain pipe section 19.

[0149] like Fig.12 As shown, in the third embodiment of realizing the automatic water discharge function disclosed in the present invention, a water outlet pipe 17 for connecting to a water supply device is installed on the machine body 1, and the water outlet pipe 17 has a water discharge port 18, and the water discharge port 18 is used to discharge water into the brewing vessel 31 through it, and the water discharge pipe section 19 where the water discharge port 18 is located is located above the silo 2 or the storage silo 51. When the silo 2 rotates to the set position with the stage 6, water can be discharged into the silo 2 through the water discharge port 18. After adopting the above structure, the powder in the silo 2 can be flushed out together with the water discharge, so that the powder can fall better and the powder and water can be pre-mixed, thereby improving the brewing effect.

[0150] like Fig.13 and Fig.14As shown, in the fourth embodiment of the automatic water discharge function disclosed in the present invention, a gap 8 is provided between adjacent silos 2, and a water outlet pipe 17 for connecting to a water supply device is installed on the machine body 1. The water outlet pipe 17 is provided above the gap 8, and the water outlet pipe 17 has a water discharge port 18, and the water discharge port 18 is used to discharge water into the brewing vessel 31 through it. The water discharge pipe section 19 where the water discharge port 18 is located is located above the silo 2. When the gap 8 moves to the top of the brewing vessel 31, the water discharge port 18 discharges water, and the water enters the brewing vessel 31 through the gap 8. The water discharge pipe section 19 where the water discharge port 18 is located is relatively fixed to the stage 6 or driven to rotate by a power device. When the stage 6 carries the silo 2 and rotates to the set position to complete the material powder delivery, the stage 6 continues to rotate so that the water discharge port 18 is facing the brewing vessel 31. After adopting this structure, the material powder delivery and the water discharge into the brewing vessel 31 are carried out successively, and the two are independent and do not affect each other.

[0151] In the embodiment of the present invention, the powder delivery device is provided with a vibration motor 16, which is used to make the powder in the silo 2 fall smoothly and prevent the powder from being difficult to slide down due to agglomeration, moisture, etc. Two implementations of the vibration motor 16 are given below.

[0152] like Figure 3 As shown, in the first embodiment of the vibration motor 16 of the present invention, the silo 2 is equipped with a vibration motor 16, and the vibration motor 16 can be installed on the side wall of the silo 2. Through the vibration of the vibration motor 16, the powder in the silo 2 can fall smoothly.

[0153] like Figure 2 and Fig.15 As shown, in the second embodiment of the vibration motor 16 of the present invention, the body 1 is equipped with a vibration motor 16, and a vibration protrusion is provided on the vibration motor 16. When the loading platform 6 drives the silo 2 to rotate to a preset position above the brewing vessel 31, the vibration protrusion on the vibration motor 16 can act on the silo 2 to cause the powder to fall. In this embodiment, only one vibration motor 16 is required, which has a simple structure and reduces costs. At the same time, the friction between the silo 2 and the loading platform 6 during the vibration process is small, which can reduce noise.

[0154] In an embodiment of the present invention, the powder delivery device is made of wholly or partially transparent materials. The silo 2, the silo door 4 and the outer shell of the powder delivery device may all be made of transparent materials, or the silo 2 and the outer shell of the powder delivery device may be made of transparent materials, or the silo 2 and the storage silo 51 may be made of transparent materials. As long as the amount of powder in the silo and the powder discharge situation can be observed from the outside, there is no limitation here.

[0155] The transparent material may be glass, plastic or other transparent materials that meet the standard grade for infant food, and is not limited here.

[0156] Of course, in some other embodiments of the present invention, the powder delivery device may also adopt other mechanisms in the prior art that can realize the powder distribution function, such as a control valve, which is not limited here.

[0157] like Figures 2 to 14 As shown, the mixing device disclosed in the present invention specifically includes a support seat 23 and a vessel seat 24. The vessel seat 24 is used to place a brewing vessel 31. The support seat 23 is connected to the machine body 1. The vessel seat 24 is movably mounted on the support seat 23. The vessel seat 24 is mounted on the support seat 23 in a manner that it can rotate around a vertical axis. The bottom of the vessel seat 24 is dynamically connected to a motor mounted on the support seat 23. The forward and reverse rotation of the motor can drive the vessel seat 24 to reverse and thus drive the brewing vessel 31 to be shaken. In some other embodiments of the present invention, the activity of the vessel seat 24 is not limited to forward and reverse rotation, and can also be shaken up and down, left and right, etc. This mixing device can prevent the powder from adhering to the inner wall of the brewing vessel 31, and it is not easy to generate bubbles during the mixing process, and the mixing effect is better.

[0158] The vessel seat 24 is cup-shaped, and an elastic snap ring 25 is installed at the edge of the vessel seat 24. When a brewing vessel 31 is placed on the vessel seat 24, the elastic snap ring 25 is sleeved on the outside of the brewing vessel 31 to fix it. The height adjustment device is arranged between the body 1 and the support seat 23, and is used to adjust the height position of the support seat 23. The elastic snap ring 25 is used to keep the brewing vessel 31 fixed to prevent the brewing vessel 31 from colliding with the vessel seat 24, and it is also convenient to remove the brewing vessel 31. The mixing device can automatically mix the beverage, further freeing both hands for easy use.

[0159] like Figures 3 to 12 As shown, in some embodiments of the present invention, the height adjustment device can realize the height adjustment of the brewing vessel, and after the brewing vessel is moved to the target position, the height position of the brewing vessel can be fixed to prevent the powder from falling outside the bottle during the falling process, causing waste of powder, and can be suitable for brewing vessels of various sizes.

[0160] Several implementations of the height adjustment device are given below. Of course, the height adjustment device is not limited to the following implementations, but also includes other implementations in the prior art that can achieve height adjustment and height position fixation of the brewing vessel.

[0161] The height adjustment device includes a sliding groove 9 arranged on the body 1, and a sliding block 221 sliding along the sliding groove 9 is arranged on the mixing device. The mixing device slides along the sliding groove 9 through the sliding block 221 to adjust the height position of the mixing device. The sliding groove 9 can limit its left and right lateral movement and front and back movement to ensure the stable lifting and lowering of the mixing device. It can be suitable for mixing vessels 31 of various heights, which is convenient for taking and placing the mixing vessels 31, preventing the mixing vessels 31 with smaller heights from sprinkling powder, and preventing the mixing vessels 31 with larger heights from being difficult to take out; at the same time, the entrance of the mixing vessel 31 can be made closer to the drop port 3 and the water outlet 18 to prevent the powder from falling to the outside of the mixing vessel 31 or the water from splashing out of the mixing vessel 31.

[0162] Furthermore, the present invention discloses the following methods for fixing the height position of the mixing device. Of course, the methods for fixing the height position of the mixing device are not limited to the following embodiments, but also include other embodiments in the prior art that can achieve the fixing of the height position of the mixing device, which are as follows:

[0163] like Fig.16 As shown, in the first embodiment in which the height position of the mixing device is fixed, after the mixing device is manually lifted to the target position, a first cushion block 13 is placed at the bottom of the mixing device to fix the height position of the mixing device.

[0164] In the second embodiment in which the height position of the mixing device is fixed, the height adjustment device includes a first fixing part that is separately arranged or installed on the machine body 1 or installed on the water storage container 20, and the mixing device is provided with a second fixing part corresponding to the first fixing part. When the mixing device is manually lifted to reach the target height, the first fixing part cooperates with the second fixing part to lock to fix the height position of the mixing device.

[0165] Among them, the first fixing part and the second fixing part can be a number of hooks or fixed blocks or slide rails and sliders used in conjunction with each other. For example, the first fixing part can be a row of hooks, and the second fixing part is a fixed groove arranged on the mixing device corresponding to the hooks. After the mixing device reaches the target height position, the fixed groove is hung on the hook to achieve the height position of the fixed mixing device; the first fixing part can also be one or several fixed bottom blocks, and the second fixing part is a fixed stopper arranged on the mixing device corresponding to the hook. After the mixing device reaches the target height position, the fixed stopper is fixedly arranged on the fixed bottom block to achieve the height position of the fixed mixing device; the first fixing part can also be a plurality of slide rails arranged at different height positions, and the second fixing part is a slider arranged on the mixing device corresponding to the hook. After the mixing device reaches the target height position, the slider slides into the slide rail at the corresponding height position to achieve the height position of the fixed mixing device.

[0166] In the third embodiment in which the height position of the mixing device is fixed, the height adjustment device includes a support frame that is separately arranged or installed on the body 1 or installed on the water storage container, and the support frame is provided with a plurality of fixing holes or fixed slide rails located at different heights, and one or more groups of bolts or buckles are provided at the corresponding fixing holes on both sides of the mixing device. When the mixing device reaches the target height, the one or more groups of bolts or buckles on the mixing device can be locked in the fixing holes or slide rails to achieve a fixed height position of the mixing device.

[0167] like Fig.17 As shown, in the fourth embodiment in which the height position of the mixing device is fixed, the height adjustment device includes at least one layer of second cushion block 131 that is separately provided or installed on the machine body 1 or installed on the water storage container 20 and is pulled out and slidably installed on the machine body 1. When the mixing device reaches the target height, at least one layer of second cushion block 131 that is separately provided or installed on the machine body 1 or installed on the water storage container 20 is pulled out to the bottom of the mixing device to fix the height position of the mixing device. The structure is simple and easy to use.

[0168] like Fig.18 and Fig.19 As shown, in the fifth embodiment in which the height position of the mixing device is fixed, the height adjustment device includes a fixed ratchet bar 26 and a stopper 27 hingedly arranged corresponding to the ratchet bar 26, the ratchet bar 26 passes through the bottom of the mixing device and guides the height adjustment of the mixing device, when the mixing device is raised or lowered to the target height position, the ratchet bar 26 cooperates with the stopper 27 to lock to fix the position of the mixing device.

[0169] Specifically, Fig. 20 and Fig.21 As shown, the block 27 includes a block body 271 hinged to the support seat 23, a pressing block 272 is provided on the side of the block body 271 away from the ratchet bar 26, an inclined surface 273 is provided on the side of the block body 271 close to the ratchet bar 26 corresponding to the ratchet bar 26, and a spring 274 is installed between the pressing block 272 and the support seat 23.

[0170] When in use, the pressing block 272 is pressed to disengage the inclined surface 273 of the block body 271 from the ratchet of the ratchet bar 26 to unlock the ratchet, thereby manually lifting the mixing device to the target position. At this time, the spring 274 is in a compressed state.

[0171] After the mixing device reaches the target position, the pressing block 272 is released, and the inclined surface 273 of the stopper body 271 is pushed by the elastic force of the spring 274 to be stuck in the ratchet teeth of the ratchet bar 26, thereby achieving the position locking of the mixing device.

[0172] like Fig. 22As shown, in some embodiments of the present invention, the height adjustment device also includes a vertical cylinder body 261 installed on the body 1 and driven to rotate by a third power device, and the mixing device includes a support seat 23. The vertical cylinder body 261 and the support seat 23 are provided with meshing driving threads 275, and the support seat 23 is vertically slidably connected to the body 1, thereby driving the mixing device to be vertically slidably connected to the body 1.

[0173] Among them, the third power device can be a motor fixed relatively to the machine body 1, and the motor shaft and the vertical cylinder body 261 are provided with meshing gears. The motor drives the vertical cylinder body 261 to rotate when it works. This is a preferred embodiment of the power device. Of course, the power device can also adopt other structures. The third power device drives the vertical cylinder body 261 to rotate. Under the meshing action of the driving thread 275, and the support seat 23 can only slide vertically, the support seat 23 can be raised and lowered, and then the mixing device can be raised and lowered. The advantage of using this structure is that the lifting of the support seat 23 is relatively stable, and the brewing vessel 31 can be lifted and lowered smoothly to achieve height position locking.

[0174] Further, such as Fig.23 As shown, in order to achieve a sliding connection between the support seat 23 and the body 1, two slide rail ribs 32 are provided on the support seat 23, and two slide rail grooves 33 are provided on the body. The two slide rail ribs 32 are respectively inserted into different slide rail grooves 33. Of course, the sliding connection method is not limited to this.

[0175] In some embodiments of the present invention, the height adjustment device includes a sliding groove 9 arranged on the body 1, and a sliding block 221 sliding along the sliding groove 9 is arranged on the mixing device. The mixing device is lifted and lowered along the sliding groove 9 through the sliding block 221. It also includes a fixed ratchet bar 26 and a stopper 27 hingedly arranged corresponding to the ratchet bar 26. The ratchet bar 26 penetrates the bottom of the mixing device and guides the mixing device to be lifted and lowered. It also includes a vertical cylinder body 261 installed on the body 1 and driven to rotate by a third power device. The vertical cylinder body 261 and the mixing device are provided with meshing driving threads 275, and the support seat 23 is vertically slidably connected to the body 1.

[0176] In some embodiments of the present invention, the water storage container 20 installed on the body 1 has an electric heating or heat preservation function, and a water pump 21 for pumping water from the water storage container 20 is installed in the water storage container 20. The water outlet pipe 17 is connected to the water outlet of the water pump 21, and the water outlet pipe 17 has a drain port 18, which is used to drain water into the storage bin 2 or the brewing vessel 31 through it.

[0177] The water storage container 20 can store warm water of suitable temperature in advance, and starting the water pump can realize automatic water discharge, so there is no need to discharge water separately each time a beverage is prepared, which is more convenient to use. The advantages of the first beverage preparation machine disclosed in the present invention are the structure of the machine body and the arrangement of the various parts on the machine body. The entire beverage preparation machine is integrated in design, compact in structure and easy to use.

[0178] The beverage mixing machine disclosed in the present invention has the advantages of a machine body structure and arrangement of various parts on the machine body, a more compact structure, a reduced number of parts, a lower failure rate, and easy use.
