In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of those skilled in the art, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0041] The utility model provides a kind of steam output module and the beverage preparation machine applied thereto. Among them, the specific form of beverage preparation machine is not limited, it can be the product of ready-made beverage modulation;It can also be the product of first powder and / or liquid preparation to obtain beverage, then modulating the beverage obtained by preparation. Among them, the modulation mode that can be realized based on steam output module can be but not limited to heating beverage using steam, foaming beverage using steam and air, etc.

[0042] Among them, beverage preparation machine includes body in addition to steam output module, body generally has front side surface and rear side surface facing user. Take coffee machine as example, body will also be formed tray along front direction protruding at front side surface, tray includes bottom disc that is formed water collecting groove by concave downward, and grating bracket that is covered at the slot of water collecting groove, grating bracket can be settled by external container, and utilize its grating to filter larger size residue. Body generally also sets beverage outlet towards down at the front side surface of body, above tray, beverage outlet can provide beverage such as milk, coffee etc. to external container placed on tray.

[0043] Therefore, steam output module is generally external to body, and is set at front side surface of body as far as possible. Steam output module is generally set at least adjacent to tray, so that steam output module can access steam to external container placed at tray.

[0044] In addition, steam output module is generally only used for circulating steam, at this time, beverage preparation machine is built-in steam source, or independent of other products as steam source of beverage preparation machine. Steam source can generate steam, and access steam into steam output module.

[0045] Specifically, please combine Figures 1 to 4 The utility model provides a steam output module includes mounting bracket 100, steam rod 200, mounting seat 300 and rotary damper 400. Among them, mounting bracket 100 is fixed to beverage preparation machine;Steam rod 200 has first end 210 and second end 220 that are oppositely arranged along its axial direction, steam rod 200 is used to access external steam source and is discharged outward via second end 220;Mounting seat 300 is detachably connected with first end 210, mounting seat 300 is rotatably installed on mounting bracket 100 around the axis extending along the radial direction of steam rod 200, to drive second end 220 to rotate synchronously in the process of external force driving its rotation;Rotary damper 400 is arranged between the rotary connection of mounting seat 300 and mounting bracket 100, when external force is removed, rotary damper 400 generates resistance between mounting seat 300 and mounting bracket 100 to hinder the reverse rotation reset of steam rod 200.

[0046] The technical scheme provided by the utility model discloses, mounting seat 300 realizes the more fast and stable installation of steam rod 200 at mounting support 100, when the steam rod 200 is rotated to a certain position under the action of external force, and then is removed, under the resistance of rotary damper 400, steam rod 200 is limited at the position, or is slowly reversed and reset to the initial position or another position, avoiding steam rod 200 resetting at the original speed or fast, leading to steam rod 200 structure being damaged or affecting the user's continuous operation of steam rod 200, thereby increasing the use flexibility of steam output module, which helps to improve the user's experience of using the steam output module.

[0047] In the design, mounting support 100 realizes the purpose of fixing the steam output module on the machine body. Since mounting seat 300 is installed on mounting support 100 along the radial direction of steam rod 200, in a feasible scheme, mounting support 100 can be arranged at one end of the rotation axis of mounting seat 300 for single-end rotation installation of mounting seat 300. However, in order to further increase the stability of mounting seat 300 and steam rod 200 during rotation, in another feasible scheme, mounting support 100 is arranged at both ends of the rotation axis of mounting seat 300, and specifically, mounting support 100 can include two side plates 110 arranged at both ends of the rotation axis of mounting seat 300 (i.e. both ends of steam rod 200 in the radial direction). Limiting holes 111 are formed in the corresponding positions of the two side plates 110 along the radial direction of steam rod 200; and shaft holes 310 are formed in mounting seat 300 corresponding to limiting holes 111. Based on this, the steam output module can further include a rotating shaft, one of the shaft holes 310 and the limiting holes 111 is fixedly connected with the rotating shaft, and the other is rotatably connected with the rotating shaft, so as to realize the purpose of rotatingly installing mounting seat 300 on the side plates 110.

[0048] Therefore, in a feasible scheme, the rotary damper 400 can be directly arranged in the shape of a shaft, i.e. constituting a rotary damping shaft. At this time, the rotary damping shaft directly constitutes the above-mentioned rotating shaft, which can realize the rotary connection between mounting seat 300 and side plates 110, and also can apply damping during rotation. Of course, in another feasible scheme, the rotary damper 400 and the above-mentioned rotating shaft are separately arranged as two independent components, but the rotary damper 400 can be arranged at the rotating shaft, and the shaft hole 310 or the limiting hole 111 rotatably connected with the rotating shaft, so as to generate sufficient damping to hinder the rotation of the rotating shaft between the outer peripheral side wall of the rotating shaft and the hole wall of the shaft hole 310 or the limiting hole 111 rotatably connected with the rotating shaft.

[0049] In addition, the mounting bracket 100 further comprises a bottom plate 120 connected between the two side plates 110. The bottom plate 120 can connect the two side plates 110 into a whole and provide sufficient strength support for the two side plates 110. The bottom plate 120 can be arranged at the side of the mounting seat 300 connected with the steam rod 200, and further, the bottom plate 120 is provided with a avoiding hole 121. The avoiding hole 121 can at least allow the steam rod 200 to pass through, and when the mounting seat 300 drives the steam rod 200 to rotate to a set position, the mounting seat 300 can abut against the side plate 110 at the circumferential side of the avoiding hole 121 of the bottom plate 120, so as to realize the stop and limit of the continuous rotation of the mounting seat 300.

[0050] Of course, when the mounting bracket 100 is mounted on the front side surface of the body of the beverage preparation machine, it can be directly fixed and connected with the front side surface of the body through the side plate 110; or in a further scheme, the mounting bracket 100 further comprises a connecting lug plate 130, which is bent and extended from the end edge of the side plate 110 along the radial direction of the steam rod 200, and is fixedly connected with the front side surface of the body.

[0051] Based on the above one or more embodiments, the mounting seat 300 and the steam rod 200 are connected and fixed, that is, under the driving of an external force, the mounting seat 300 and the steam rod 200 can rotate synchronously. The rotation angle range of the steam rod 200 is not limited, and when the mounting bracket 100 is fixed on the front side surface of the body, the rotation axis of the steam rod 200 and the mounting seat 300 extends in the transverse direction, that is, the steam rod 200 can swing in the up-down direction. In view of this, the steam rod 200 can be specifically arranged to be rotatable between 0° and 180°, that is, the second end 220 of the steam rod 200 can be rotated from the opening vertically downward to the opening vertically upward. Of course, in order to make the rotation of the steam rod 200 more practical, the steam rod 200 can also be specifically arranged to be rotatable between 0° and 90°, that is, the second end 220 of the steam rod 200 can be rotated from the opening vertically downward to the opening forward.

[0052] During the entire rotation stroke of the steam rod 200, a first position and a second position spaced from each other can be defined. It can be understood that the first position and the second position can be any position on the entire rotation stroke of the steam rod 200, for example, at least one of the first position and the second position is any limit position on the entire rotation stroke of the steam rod 200; or for example, at least one of the first position and the second position is any intermediate position between the two limit positions on the entire rotation stroke of the steam rod 200. In addition, the first position and the second position can be two positions marked in advance by any suitable means; or the first position and the second position are two positions arbitrarily selected by a user during the operation of the steam rod 200.

[0053] When the first position and the second position are defined as described above, and the steam rod 200 is driven to rotate from the first position to the second position by an external force applied manually by a user or automatically by a preset power component, if the external force is removed, the hindering effect caused by the resistance generated by the rotation damper 400 can be set and limited in advance according to actual needs:

[0054] For example, in an embodiment, the resistance generated by the rotation damper 400 can be defined to reverse-rotate and reset the steam rod 200 from the current second position to the first position, but the difference is that if the speed at which the steam rod 200 is driven to rotate from the first position to the second position by the external force is defined as a first speed, and the speed at which the steam rod 200 is reset from the second position to the first position by the resistance generated by the rotation damper 400 is defined as a second speed, the second speed is set to be less than the first speed. That is, when the steam rod 200 is reverse-rotated and reset by the resistance generated by the rotation damper 400, it is reverse-rotated and reset at a slow speed, and the specific second speed can be adjusted according to actual needs. Slow reverse-resetting can make it unnecessary to manually or by the power component described above repeatedly apply a reverse-driving force during the reverse-resetting process, which is more simple, efficient, energy-saving, and consumption-reducing, and can also make the reverse-resetting process of the steam rod 200 smooth and safe.

[0055] Or in another embodiment, if a third position is further defined between the first position and the third position, and the third position can be at any position between the first position and the second position as described above; the third position can be a fixed position marked by any suitable means; or it can be any position between the first position and the second position naturally associated based on the second speed described above. At this time, when the external force driving the steam rod 200 to rotate from the first position to the second position is removed, the resistance generated by the rotation damper 400 fixes the steam rod 200 at the third position. It should be noted that at this time, the speed during reverse-rotation to the third position is a third speed, and the third speed can be a speed comparable to the first speed described above, a speed comparable to the second speed described above, or a speed other than the first speed and the second speed described above, without limitation.

[0056] Or in yet another embodiment, after the external force drives the steam rod 200 to rotate from the first position to the second position and the external force is removed, the resistance generated by the rotation damper 400 fixes the steam rod 200 at the second position. That is, in the natural state after the external force is removed, the resistance generated by the rotation damper 400 is sufficient to balance with other external forces (such as the gravity of related components, etc.) at the position, so that the steam rod 200 is balanced and stable at the second position, neither continuing to rotate forward nor rotating backward to reset. In this way, it is more convenient for the user to rotate the steam rod 200 to the second position to perform other operations, and the steam rod 200 is locked and fixed at the current second position, so that the user can continue to operate when returning.

[0057] It should be noted that in any of the above embodiments, the first position and / or the second position are provided in multiple positions in the rotation stroke of the steam rod 200. When the entire rotation stroke of the steam rod 200 is provided in stages, the first position and / or the second position can be any stage position provided in the entire rotation stroke of the steam rod 200. When the entire rotation stroke of the steam rod 200 is provided in stages, the first position and / or the second position can be any position in the entire rotation stroke of the steam rod 200.

[0058] In addition, based on one or more of the above embodiments, regarding the installation of the steam rod 200 on the mounting seat 300:

[0059] In an embodiment, the mounting seat 300 is provided with a first mounting hole 320 along the axial direction of the steam rod 200, and the first mounting hole 320 includes a first hole section 321 and a second hole section 322 connected in sequence; and the first end 210 of the steam rod 200 is sealingly installed in the second hole section 322. Specifically, the rod section (for the sake of understanding, the rod section is defined as a plug-in rod section below) connected to the first end 210 of the steam rod 200 can be sealingly installed in the second hole section 322. The plug-in rod section can be directly plugged and fixed with the second hole section 322; or the plug-in rod section can be plugged and fixed with the second hole section 322 through other components, such as a joint 700. In addition, the sealing connection mode between the plug-in rod section (and / or, for example, the joint 700) and the second hole section 322 is not limited, which can be directly achieved by interference fit, or can be achieved by structures such as a sealing ring.

[0060] The steam output module further includes a temperature sensor 500, and the temperature sensor 500 includes a connection section 510, an extension section 530, and a measurement section 520 connected in sequence, wherein the extension section 530 is sequentially arranged in the first mounting hole 320 and the steam rod 200; the connection section 510 extends outward from the first hole section 321 to be electrically connected with an external electric control device; and the measurement section 520 extends outward from the second end 220 to measure the temperature value of the liquid in the external container when the steam rod 200 is inserted into the external container.

[0061] When the extension section 530 is entirely arranged in the hollow structure of the steam rod 200, the outer peripheral side wall of the extension section 530 and the inner peripheral side wall of the steam rod 200 are at least partially spaced apart, forming a flow channel 230 in which steam can flow. Generally, the hollow structure of the steam rod 200 is in the shape of a regular cylinder, and the extension section 530 is also generally in the shape of a regular cylinder. When the extension section 530 is entirely arranged in the hollow structure of the steam rod 200, the extension section 530 can be eccentrically arranged, that is, the central axis of the steam rod 200 is substantially parallel to but not collinear with the central axis of the extension section 530. At this time, if the outer peripheral side wall of the extension section 530 and the inner peripheral side wall of the steam rod 200 are partially in contact and partially spaced apart, the flow channel 230 formed therebetween is generally a circumferentially discontinuous chamber; if the outer peripheral side wall of the extension section 530 and the inner peripheral side wall of the steam rod 200 are not in contact at all, the flow channel 230 formed therebetween is generally a circumferentially continuous, eccentric annular chamber. In the present embodiment, the steam rod 200 and the extension section 530 are coaxially arranged. That is, the central axis of the steam rod 200 is substantially collinear with the central axis of the extension section 530. At this time, the outer peripheral side wall of the extension section 530 and the inner peripheral side wall of the steam rod 200 are not in contact at all, and the flow channel 230 formed therebetween is a circumferentially continuous, concentric annular chamber, that is, an annular flow channel 230. The annular flow channel 230 is arranged such that the flow speed, flow volume, and other parameters of the flow between the extension section 530 and the steam rod 200 in all directions are consistent, which helps to further improve the stability of the steam flow.

[0062] Next, the mounting seat 300 is further provided with a second mounting hole 330, the second mounting hole 330 is in communication with the first mounting hole 320, and the extension direction of the second mounting hole 330 is crosswise arranged with the extension direction of the first mounting hole 320; the second mounting hole 330 is used to be connected in communication with the external steam source through the pipeline structure. By crosswise arranging the second mounting hole 330 with the first mounting hole 320, that is, by tilting the second mounting hole 330 relative to the first mounting hole 320, the external steam can be tilted into the steam rod 200, which helps to avoid the airflow from rapidly rushing into the passage of the steam rod 200.

[0063] Further, in an embodiment, the first mounting hole 320 further includes a transition hole section 323 between the first hole section 321 and the second hole section 322, and the second mounting hole 330 is in communication with the transition hole section 323; at least in the direction from the connection between the second mounting hole 330 and the transition hole section 323 to the second hole section 322, the hole diameter of the transition hole section 323 is arranged to increase. The transition hole section 323 reserves a larger buffer space for the steam entering the steam rod 200, which helps to make the airflow entering the steam rod 200 more stable. The hole diameter of the transition hole section 323 can be arranged to increase in a multi-stage stepped manner, or can be arranged to gradually increase in the shape of a conical surface.

[0064] Further, when the temperature sensor 500 further comprises the extension section 530 arranged in the steam rod 200, the outer wall of the extension section 530 is spaced from the inner wall of the steam rod 200 to form the flow channel 230, and the radial cross-sectional area of the flow channel 230 is smaller than that of the transition hole section 323. In this way, the flow rate of the steam entering the flow channel 230 at the transition hole section 323 is faster and stable, and the steam can flow to the second end 220 more quickly, facilitating the rapid discharge of the steam.

[0065] In addition, the steam output module can further comprise a protective sleeve 600, which can be sleeved at the connection between the mounting seat 300 and the steam rod 200, so as to transition the size and shape differences between the mounting seat 300 and the steam rod 200 in appearance, and help to protect the connection between the mounting seat 300 and the steam rod 200 to a certain extent.

[0066] The above is only the preferred embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields under the utility model concept of the present application are included in the patent protection range of the present application.
