[0002] In daily life, foaming is often used when making certain special drinks to enhance their texture and appearance. For example, making coffee foam, fruit juice foam, and cappuccino requires frothing milk. When liquid milk is continuously stirred, the surface tension of the milk proteins creates numerous tiny bubbles, causing the liquid milk to expand and become foamy milk.

Detailed Implementation

[0038] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0039] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] This application provides a foaming device 10. Figure 1 This is a schematic diagram of the structure of an embodiment of the foam-making device 10 provided in this application. Figure 2 yes Figure 1 A front view of the foaming device 10 in the middle.

[0041] Combination Figure 1as well as Figure 2 The foam making device 10 includes a base 11, which constitutes the main structure of the foam making device 10 and is used for fixing and installing other components.

[0042] Specifically, the base 11 includes a base 111 and a main body 112. The main body 112 is disposed on the base 111, and the height direction of the main body 112 is perpendicular to the upper surface of the base 111. At this time, the height direction of the main body 112 is the height direction of the base 11.

[0043] The base 11 is provided with a receiving position 113 for receiving the receiving member 20. The receiving position 113 is provided on the base 111 and located on one side of the base 111, and the main body 112 is provided on the other side of the base 111. At this time, the receiving position 113 is located on one side of the main body 112 and is arranged adjacent to it.

[0044] Figure 3 yes Figure 1 The diagram shows the foam-making device 10 and the container 20 in action.

[0045] like Figure 3 The receiving member 20 is supported on the receiving position 113, and the receiving member 20 is located on one side of the main body 112 and is disposed adjacent to the main body 112. The size of the receiving position 113 can be set according to the size of the receiving member 20 that needs to be supported, and there is no specific limitation. The receiving member 20 can be a container capable of holding liquids such as milk.

[0046] Figure 4 yes Figure 2 The foaming device 10 shown is a cross-sectional view along section line AA.

[0047] Combination Figure 4 The foaming device 10 also includes a steam generator 12, which is located on the base 11 and connected to a water source. Water from the water source can be introduced into the steam generator 12, which is used to heat the water to form steam.

[0048] The water source can be a water source other than the foaming equipment 10, or it can be a water source provided by the foaming equipment 10 itself. The water in the water source is introduced into the steam generator 12 through a pipe. The steam generator 12 further vaporizes the introduced water to form steam.

[0049] Specifically, the steam generator 12 may include a housing, a metal conduit, and a heating element disposed within the housing. The heating element may be tubular and heats the water by generating heat. The inlet end of the metal conduit is connected to a water source, and the water introduced into the metal conduit is heated by the heating element and then discharged from its steam outlet end. The metal conduit may be wound around the heating element, thereby effectively heating the metal conduit and allowing the water inside the metal conduit to rapidly vaporize and be discharged from the steam outlet end.

[0050] Combination Figure 4 The foam-generating device 10 also includes a steam pipe 13, which has a steam outlet. The steam pipe 13 is connected to a water source and a steam generator 12. The hollow steam pipe 13 forms a flow channel 131, which is connected to the steam outlet. Steam from the steam generator 12 can be introduced into the flow channel 131 and then discharged to the outside of the steam pipe 13 through the steam outlet.

[0051] In some specific embodiments, the steam guide pipe 13 extends along the height direction of the base 11 and is disposed above the receiving position 113. The steam guide pipe 13 can move closer to or further away from the receiving position 113 along the height direction of the base 11. In summary, the steam guide pipe 13 extends along the height direction of the main body 112, and the length direction of the steam guide pipe 13 is consistent with the height direction of the main body 112. The steam guide pipe can move along the height direction of the main body 112. Through the movement of the steam guide pipe 13, it can move closer to or further away from the receiving member 20.

[0052] In some specific embodiments, in order for the steam pipe 13 to move closer to or further away from the receiving position 113 along the height direction of the base 11, the steam pipe 13 may move while the receiving position 113 remains stationary, or the steam pipe 13 may remain stationary while the receiving position 113 moves, thereby realizing the movement of the steam pipe 13 relative to the receiving position 113.

[0053] Figure 5 yes Figure 1 The diagram shown is a structural schematic after removing the main body 112. Figure 6 yes Figure 5 A schematic diagram of a portion of the structure shown. Figure 7 yes Figure 6 The diagram shows the structure from another perspective.

[0054] The foam-making equipment 10 includes a water supply system, which is located on the base 11 and is used to supply water to the foam-making equipment 10. (Specifically combined...) Figures 5-7The water supply system may include a water storage tank 151, a water pump, and conduits. The water storage tank 151 constitutes the water source, which is the water source provided by the foam-generating device 10. The water pump is connected to the water storage tank 151 through a conduit, and the water pump is used to draw water from the water storage tank 151 to introduce it into other devices.

[0055] Specifically, the water pump is also connected to the steam generator 12 and the steam pipe 13 through a conduit. The water pump can draw water from the water storage tank 151 into the steam generator 12 on the one hand, and draw water from the water storage tank 151 into the steam pipe 13 on the other hand.

[0056] It should be understood that the water pump can draw water from the water storage tank 151 to the steam generator 12 or to the steam pipe 13 separately, so that the water storage tank 151 can supply water to the steam generator 12 and the steam pipe 13 separately.

[0057] Combination Figure 6 The water pump includes a first water pump 1521, which is connected to a water storage tank 151 via a first conduit 1531 and also connected to a steam pipe 13 via a second conduit 1532. The first water pump 1521 draws water from the water storage tank 151 through the first conduit 1531 and directs the drawn water into the steam pipe 13 through the second conduit 1532.

[0058] Combination Figure 7 The water pump also includes a second water pump 1522, which is connected to a water storage tank 151 via a third conduit 1533 and a steam generator 12 via a fourth conduit 1534. The steam generator 12 is connected to a steam pipe 13 via a fifth conduit 1535. The second water pump 1522 draws water from the water storage tank 151 via the third conduit 1533 and introduces the drawn water into the steam generator 12 via the fourth conduit 1534. The steam outlet of the steam generator 12 is connected to the fifth conduit 1535, so that the steam generated by the steam generator 12 is introduced into the steam pipe 13 via the fifth conduit 1535.

[0059] Combination Figure 4 as well as Figure 7 One end of the second conduit 1532 is connected to one end of the fifth conduit 1535, and then connects to the steam pipe 13 through the same conduit segment. The same conduit segment connected to the second conduit 1532 and the fifth conduit 1535 is the sixth conduit 1536, which is connected to the upper end of the steam pipe 13.

[0060] In conjunction with the above, in some specific embodiments, the water source system includes a water storage tank base (not shown in the figure). The water storage tank base is connected to the first conduit 1531 and the third conduit 1533, respectively. An inlet is provided at the upper end of the water storage tank base. The water storage tank 151 can be mounted on the water storage tank base, and its outlet is connected to the inlet of the water storage tank base. In this case, water in the water storage tank 151 can be introduced into the water storage tank base, and then into the first conduit 1531 and the third conduit 1533.

[0061] Specifically, the water storage tank 151 can be detachably installed with the water storage tank base, thereby enabling the replenishment of water to the water source system by replacing the water storage tank 151. The water storage tank 151 can be a medium or large bottled mineral water that is readily available on the market, to conveniently replenish the water source system.

[0062] Combination Figure 4 as well as Figure 5 The foam making equipment 10 is equipped with a control device 16, which includes a housing 161 and a control device 162. Part of the control device 162 is located inside the housing 161, and the rest is located outside the housing 161. The user controls the foam making equipment 10 through the control device 162.

[0063] Specifically, the controller 162 is electrically connected to the steam generator 12, the first water pump 1521, and the second water pump 1522, respectively. Upon receiving control commands from the user, the controller 162 can control the steam generator 12, the first water pump 1521, and the second water pump 1522 to operate. It should be understood that when steam needs to be supplied to the steam pipe 13, the controller 162 controls the second water pump 1522 and the steam generator 12 to operate.

[0064] Figure 8 yes Figure 1 An exploded view of part of the structure of the foam-making equipment 10. Figure 9 yes Figure 1 A schematic diagram showing the cooperation relationship between the lifting and fixing frame 17 and the main body 112 in the foaming equipment 10.

[0065] Combination Figure 8 as well as Figure 9 In some specific embodiments, the foaming device 10 includes a lifting and fixing frame 17, which is disposed on the base 11 and can move in the height direction of the base 11. The steam pipe 13 is disposed on the lifting and fixing frame 17.

[0066] Based on the above, the lifting and fixing frame 17 can be installed on one side of the main body 112, in which case the lifting and fixing frame 17 can move in the height direction of the main body 112. The main body of the lifting and fixing frame 17 is positioned directly opposite the receiving position 113, and the steam pipe 13 is installed on the main body of the lifting and fixing frame 17 so as to be directly opposite the receiving position 113, so that the steam pipe 13 can be smoothly inserted into the receiving member 20.

[0067] In some embodiments, the lifting and fixing frame 17 is specifically configured such that the side wall of the base 11 is provided with a sliding groove 1121 extending along its height direction, that is, the sliding groove 1121 is provided on one side of the main body 112. The lifting and fixing frame 17 includes a main body bearing part 171 and a sliding part 172. The sliding part 172 is provided on one side of the main body bearing part 171, and the lifting and fixing frame 17 is slidably disposed in the sliding groove 1121 through the sliding part 172.

[0068] Specifically, the main support portion 171 can be arranged in the form of a circular frame, or it can be in other shapes. The number of sliding portions 172 can be multiple, in which case multiple sliding grooves 1121 are correspondingly provided. Figure 12 The example shows that there are two sliding parts 172 and two grooves 1121.

[0069] Based on the above, the bottom wall of the housing 161 of the control device 16 is fixed to the main support part 171, and the steam pipe 13 is fixed to the bottom wall of the housing 161. The sixth conduit 1536 passes through the side wall and bottom wall of the housing 161 in sequence and then communicates with the steam pipe 13.

[0070] More specifically, the frictional force between the sliding part 172 and the slide groove 1121 is greater than a preset value, so that the lifting fixing frame 17 can maintain its position fixed by the frictional force between it and the slide groove 1121 after it stops sliding. In this embodiment, the lifting fixing frame 17 can be manually pulled, thereby moving the lifting fixing frame 17 in the height direction of the base 11. When the user pulls the lifting fixing frame 17 to a desired position, due to the sufficiently large frictional force between the sliding part 172 and the slide groove 1121, the lifting fixing frame 17 can maintain its position fixed relative to the receiving member 20, so that the steam pipe 13 maintains its position fixed relative to the receiving member 20.

[0071] Figure 10 yes Figure 8 A schematic diagram of the middle section. Figure 11 yes Figure 10 The structure shown is a cross-sectional view along section line BB. Figure 12 yes Figure 11 An enlarged structural diagram of region A in the diagram. Figure 13 yes Figure 10 Exploded view of the middle section of the structure. Figure 14yes Figure 13 A schematic diagram showing the fit between the steam pipe 13 and the rotating component 18. Figure 15 yes Figure 14 The structure shown is a cross-sectional view along section line CC. Figure 16 yes Figure 14 The structure shown is a cross-sectional view along section line DD.

[0072] Combination Figure 13 The sidewall of the steam pipe 13 is provided with a plurality of first steam outlet holes 132 along its circumference. The first steam outlet holes 132 are connected to the flow channel 131 and can exhaust the steam in the flow channel 131. The plurality of first steam outlet holes 132 can be arranged at equal intervals at the lower end of the steam pipe 13, and the plurality of first steam outlet holes 132 are located at the same height on the steam pipe 13.

[0073] Combination Figure 16 The central axis L1 of the first steam outlet 132 is inclined relative to the radial direction L2 of the steam guide pipe 13. For example... Figure 16 The angle between the central axis L1 of the first steam outlet 132 and the radial direction L2 of the steam guide pipe 13 is S. The angles between the central axis L1 of the plurality of first steam outlets 132 and the radial direction L2 of the steam guide pipe 13 are equal for ease of arrangement.

[0074] Combination Figure 12 , Figure 13 as well as Figure 16 The foam-generating device 10 also includes a rotating ring 18 and an agitator 19. The rotating ring 18 is sleeved on the outer wall of the steam pipe 13, and the agitator 19 is fixed on the rotating ring 18. The rotating ring 18 can rotate along the axis of the steam pipe 13. The agitator 19 can be fixed on the outer wall of the rotating ring 18 away from the steam pipe 13. When the rotating ring 18 rotates, it drives the agitator 19 to rotate, thereby causing the agitator 19 to agitate the liquid in the container 20, thereby generating foam.

[0075] Combination Figure 12 In some specific embodiments, the agitator 19 may specifically include a fixed ring 191 and a spring ring 192. The fixed ring 191 is disposed inside the spring ring 192 and fixes the spring ring 192 to the outer wall of the rotating ring 18. In this case, the spring ring 192 surrounds the outer wall of the rotating ring 18 and is fixed to the rotating ring 18 by the fixed ring 191. When the rotating ring 18 rotates, it drives the spring ring 192 to rotate, thereby agitating the milk. When agitating milk with the agitator 19 to froth it, the spring ring 192 allows more air to enter the milk foam, making the foam softer.

[0076] Combination Figure 16The inner wall of the rotating ring 18 has multiple drive grooves 181 with openings facing the first steam outlet 132. The first steam outlet 132 is used to guide steam into the drive grooves 181. The drive grooves 181 can be arranged in a one-to-one correspondence with the first steam outlet 132, such as... Figure 16 As shown. Of course, the number of drive slots 181 may be more or less than the number of first steam outlet holes 132, and no specific limitation is made here.

[0077] It should be understood that when the rotating ring 18 is set on the outer wall of the steam pipe 13, the gap between the inner wall of the rotating ring 18 and the outer wall of the steam pipe 13 is small. After the steam is discharged from the first steam outlet 132, only a small part will be discharged from the gap and most of it will be guided to the drive groove 181.

[0078] In conjunction with the above, when steam is led out from the first steam outlet 132 into the drive tank 181, the steam impacts the drive tank 181, causing the drive tank 181 to drive the rotating ring 18 to rotate, thereby driving the agitator 19 to rotate and foaming.

[0079] It should be understood that, due to the angle S between the central axis L1 of the first steam outlet 132 and the radial direction L2 of the steam guide pipe 13, the airflow from the first steam outlet 132 forms an angle with the radial direction of the rotating ring 18. This causes the airflow to exert a driving force on the rotating ring 18 at an angle to its radial direction, which in turn drives the rotating ring 18 to rotate. During the rotation of the rotating ring 18, the same first steam outlet 132 continuously guides airflow into different driving slots 132, enabling the same steam outlet 132 to drive different driving slots 132.

[0080] In some specific embodiments, the central axis L3 of the drive groove 181 is also inclined relative to the radial direction L2 of the steam pipe 13 and in the same direction as the first steam outlet 132, and the inclination angle of the first steam outlet 132 is equal to the inclination angle of the drive groove 181. At this time, the inclination direction of the plurality of first steam outlets 132 relative to the radial direction L2 of the steam pipe is the same, so that the force generated by the steam discharged from the first steam outlet 132 on the drive groove 181 causes the rotating ring to have a tendency to move in the same direction.

[0081] It should be understood that, Figure 16 The driving groove 181 in the diagram does not show a scheme where its central axis L3 is inclined L2 relative to the steam pipe 13. When the central axis L3 of the driving groove 181 is also inclined radially L2 relative to the steam pipe 13 and in the same direction as the first steam outlet 132, both the central axis L3 of the driving groove 181 and the central axis L1 of the first steam outlet 132 can be inclined clockwise or counterclockwise. For example... Figure 16This shows that the central axis L1 of the first steam outlet 132 is tilted counterclockwise. When the tilt angle of the first steam outlet 132 is equal to the tilt angle of the rotating ring 18, the angle S between the central axis L1 of the first steam outlet 132 and the radial direction L2 of the steam guide pipe 143 is equal to the angle between the central axis L3 of the drive groove 181 and the radial direction L2 of the steam guide pipe 13.

[0082] By setting the drive groove 181 and the first steam outlet 132 at an inclination in the same direction, the steam discharged from the first steam outlet 181 can be better introduced into the drive groove 181, so that the drive groove 181 can better drive the rotating ring.

[0083] Continue to combine Figure 16 In some specific embodiments, the cross-section of the drive groove 181 in the plane perpendicular to its depth direction is circular, and the cross-section of the drive groove 181 gradually decreases in the direction away from the steam pipe 13.

[0084] Specifically, the depth direction of the drive groove 181 can be aligned with the direction of the central axis L3 of the drive groove. Combined with... Figure 16 When the drive groove 181 is not inclined relative to the steam pipe 13, the depth direction of the drive groove 181 is the radial direction of the steam pipe 13.

[0085] By gradually reducing the cross-section of the drive groove 181 away from the steam pipe 13, the drive groove 181 takes on a conical or cone-like shape. In this embodiment, even if the central axis L3 of the drive groove 181 is not inclined relative to the radial direction L2 of the steam pipe 13, the steam discharged from the first steam outlet 132 can still effectively impact the inner wall of the drive groove 181, thereby enabling the drive groove 181 to effectively drive the rotating ring 18.

[0086] Figure 17 yes Figure 14 An exploded view of the structure shown. Figure 18 yes Figure 17 An enlarged structural diagram of region B in the diagram.

[0087] Combination Figure 17 as well as Figure 18 The lower end of the steam pipe 13 is provided with a limiting groove 133, the opening of the first steam outlet 132 faces the limiting groove 133, and the rotating ring 18 is disposed in the limiting groove 133 to rotate within the limiting groove 133.

[0088] Specifically, the outer wall of the lower end of the steam guide pipe 13 is recessed towards the flow channel 131 to form a limiting groove 133. The size of the limiting groove 133 can be adapted to the size of the rotating ring 18, thereby keeping the rotating ring 18 in a relatively fixed position when rotating within the limiting groove 133, so that the steam discharged from the first steam outlet 132 can be well guided into the drive groove 181. Furthermore, the setting of the limiting groove 133 makes it difficult for the steam discharged from the first steam outlet 132 to be discharged from the gap between the rotating ring 18 and the steam guide pipe 13.

[0089] Combination Figure 15 as well as Figure 18 In some specific embodiments, the steam pipe 13 is provided with a second steam outlet 134, which is connected to the flow channel 131. The second steam outlet 134 is located above the first steam outlet 132, and steam is discharged through the second steam outlet 134 to heat the liquid in the container 20.

[0090] Specifically, when the steam pipe 13 is inserted into the liquid used for frothing, the steam generator 12 introduces steam into the guide channel 131, and then discharges it through the first steam outlet 132 and the second steam outlet 134 respectively. The steam discharged through the first steam outlet 132 is used to drive the rotating ring 18 to rotate to achieve foaming, and the steam discharged through the second steam outlet 134 is used to heat the liquid to facilitate foaming. For example, when using milk to froth milk, the steam discharged through the second steam outlet 134 can heat the milk to about 60°C.

[0091] Figure 19 yes Figure 13 A schematic diagram of the structure of the sleeve assembly 21 in the middle. Figure 20 yes Figure 19 A sectional view of the sleeve assembly 21 along section line EE.

[0092] Combination Figure 13 , Figure 19 as well as Figure 20 In some specific embodiments, the foaming device 10 further includes a sleeve assembly 21, the upper end of which is a closed end and fixed on the lifting and fixing frame 17, the lower end of which is an open end, the upper end of the steam pipe 13 is disposed in the inner cavity of the sleeve assembly 21, and the upper end of the steam pipe 13 can move within the sleeve assembly 21.

[0093] Specifically, the sleeve assembly 21 is fixed to the bottom wall of the housing 161, and the sleeve assembly 21 forms a downward-facing receiving groove. The upper end of the steam guide pipe 13 is disposed in the receiving groove of the sleeve assembly 21. The closed end of the upper end of the sleeve assembly 21 has a through hole, and the sixth guide pipe 1536 passes through the through hole of the closed end of the sleeve assembly 21 and extends into the receiving groove to communicate with the steam guide pipe 13.

[0094] The foaming device 10 also includes an elastic element 22, which is disposed in the inner cavity of the sleeve assembly 21. The first end of the elastic element 22 is fixed to the closed end, and the second end of the elastic element 22 is used to abut against the steam pipe 13.

[0095] Specifically, the elastic element 22 can extend along the height direction of the base 11, and the elastic element 22 can be compressed or extended in the height direction of the base 11. At this time, the first end of the elastic element 22 is the top end of the elastic element 22, and the second end of the elastic element 22 is the bottom end of the elastic element 22. The first end of the elastic element 22 is fixed to the bottom wall of the closed end so that the elastic element 22 can extend and retract within the receiving groove of the sleeve assembly 21. When there is no external object in contact with the steam pipe 13, the second end of the elastic element 22 can be in contact with the steam pipe 13 or spaced apart, without specific restrictions.

[0096] It should be understood that there is a certain gap between the top end of the steam pipe 13 and the inner wall of the closed end, and the elastic element 22 is at least partially disposed at the gap between the steam pipe 13 and the closed end.

[0097] Specifically, after the lifting and fixing frame 17 moves downward until the lower end of the steam pipe 13 comes into contact with other objects, when the lifting and fixing frame 17 moves further downward, the steam pipe 13 comes into contact with the second end of the elastic element 22 to compress the elastic element 22. At this time, the steam pipe 13 moves towards the closed end within the sleeve assembly 21, while compressing the elastic element 22.

[0098] Combination Figure 20 as well as Figure 17 In some specific embodiments, the sleeve assembly 21 forms a stepped portion 211, and the outer wall of the steam pipe 13 is provided with a limiting portion 135. The lower end of the limiting portion 135 abuts against the inner wall of the stepped portion 211 to support the steam pipe 13, and the upper end of the limiting portion 135 is used to abut against the second end of the elastic member 22.

[0099] Specifically, the stepped portion 211 formed on the inner wall of the sleeve assembly 21 divides its inner cavity into upper and lower sub-cavities, with the diameter of the upper sub-cavity being larger than that of the lower sub-cavity. The limiting portion 135 of the steam pipe 13 is located in the upper sub-cavity and abuts against the inner wall of the stepped portion 211 to ensure that the limiting portion 135 of the steam pipe 13 will not slide out from the lower sub-cavity.

[0100] Based on the above, the limiting part 135 can be arranged in a ring shape. In this case, there can be multiple elastic elements 22, which are arranged in a ring on the limiting part 135.

[0101] Combination Figure 19 as well as Figure 20The sleeve assembly 21 specifically includes a main sleeve 212 and a capping part 213. The capping part 213 covers the opening at the upper end of the main sleeve 212, thereby forming the closed end of the sleeve assembly 21.

[0102] Based on the above, the main sleeve 212 forms a stepped portion 211 to create two sub-cavities within the main sleeve 212. The cap portion 213 is fixed to the bottom wall of the housing 161, thereby fixing the sleeve assembly 21, and the first end of the elastic member 22 abuts against the lower end of the cap portion 213.

[0103] Combination Figure 10 as well as Figure 11 In some specific embodiments, the foaming device 10 further includes a cover 23, which is fixed to the sleeve assembly 21, through which the sleeve assembly 21 passes. The cover 23 is used to close the upper opening of the container 20 during the descent of the steam pipe 13, thereby ensuring that the steam effectively heats the liquid inside the container 20. The size of the cover 23 is adapted to the upper opening of the container 20, so that the cover 23 can completely seal the upper opening of the container 20.

[0104] Of course, in order to ensure that the air pressure inside the container 20 is within a safe range, a steam vent can be provided on the cover 23 to remove excess steam from the container 20.

[0105] With the sleeve assembly 21 and the elastic element 22 provided above, when the lower end of the steam pipe 13 abuts against the object inside the container 20, if the cover 23 is still located above the opening of the container 20, the lifting and fixing frame 17 can be pressed down further to compress the elastic element 22. The steam pipe 13 does not move, but the cover 23 moves downward, so that the cover 23 closes the opening of the container 20.

[0106] In summary, the elastic element 22 can provide a certain displacement of the cover 23 when the steam pipe 13 is pressed against the object inside the container 20, but the cover 23 is not closed on the container 20, so that the cover 23 closes on the upper opening of the container 20.

[0107] In combination with the specific arrangement of the sleeve assembly 21 described above and Figure 11 , Figure 19 , Figure 20 In some embodiments, the sleeve assembly 21 further includes a limiting sleeve 214, which is screwed onto the outer wall of the main sleeve 212. The limiting sleeve 214 may be screwed onto the lower end of the main sleeve 212. The stepped portion 211 and the limiting sleeve 214 are arranged opposite to each other. The cover 23 is disposed between the outer wall of the stepped portion 212 and the limiting sleeve 214. The limiting sleeve 214 can press the cover 23 against the stepped portion 212 by rotation, specifically against the outer wall of the stepped portion 211, thereby fixing the cover 23.

[0108] Furthermore, since the limiting sleeve 214 is screwed onto the lower part of the main sleeve 212, different models of cover 23 can be pressed against the lower wall of the stepped portion 211 by adjusting the amount of engagement with the main sleeve 212, thereby enabling the installation of different models of cover 23. Moreover, when it is necessary to remove the cover 23, the limiting sleeve 214 can be removed from the main sleeve 212 to remove the cover 23; the reverse is true when installing the cover 23.

[0109] Combination Figure 12 In some specific embodiments, the foaming device 10 includes a temperature sensor (not shown). The wall of the steam pipe 13 includes an inner wall 136 and an outer wall 137 spaced apart. The temperature sensor is disposed between the inner wall 136 and the outer wall 137 and is in contact with the outer wall 137. The temperature sensor is used to obtain the temperature of the liquid inside the container 20 through the outer wall 137. By measuring the temperature inside the container 20 through the outer wall 137 of the steam pipe 13, the temperature of the liquid inside the container 20 can be accurately measured.

[0110] Specifically, the temperature sensor is arranged in a sheet shape. The temperature sensor can be a PTC (Positive Temperature Coefficient) sensor, which is made of semiconductor material with a large positive temperature coefficient and can accurately measure temperature.

[0111] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
