DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0035] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0036] The steam wand 200 is a common structure of a beverage processing device. The steam wand 200 outputs hot steam, which can heat the beverage and / or foam the milk. Since the steam wand 200 needs to contact the beverage when in use, it needs to be cleaned after use. Usually, the steam wand 200 is cleaned by an operator. The operator wipes the steam wand 200 with a wet cloth or washes the steam wand 200 with water, which can clean the outer surface of the steam wand 200, but it is difficult to clean the internal channel of the steam wand 200. And if the cloth used to clean the steam wand 200 is not clean, bacteria may spread to the steam wand 200.

[0037] The embodiment of the present application provides a steam rod cleaning mechanism 10, a beverage processing device and a coffee machine 1000, which can solve the technical problem of poor cleaning effect of the current steam rod to a certain extent.

[0038] The first aspect of the present application provides a steam wand cleaning mechanism, which is installed on an equipment body of a device that needs to be equipped with a steam wand. The device is usually a beverage processing device, such as a milk tea machine, a coffee machine, etc. The steam wand cleaning mechanism can achieve self-cleaning of the steam wand.

[0039] See also Figure 1 , shows the overall structure of a coffee machine equipped with a steam wand cleaning mechanism 10. The steam wand cleaning mechanism 10 includes a switch device 100, a steam wand 200, and a cleaning unit (not shown in the figure). The steam wand 200 is disposed in the device body 20 of the coffee machine, the cleaning unit is disposed in the device body 20, and the cleaning unit is connected to the steam wand 200, and is used to provide a fluid medium for cleaning to the steam wand 200. Among them, the steam wand 200 can be operably acted on the switch device 100, so that the cleaning unit responds to the switch device 100 and provides a fluid medium to the internal channel of the steam wand 200. The internal channel of the steam wand 200 is not limited to the steam channel. In some embodiments, an air pipe is integrated inside the steam wand, and the air channel also belongs to the internal channel of the steam wand 200.

[0040] The steam wand 200 is used to inject steam into the beverage in the container to change the characteristics of the beverage, such as using the steam wand 200 to make milk foam, using the steam wand 200 to heat the beverage, etc. After the steam wand 200 is used, the beverage will remain in the internal channel of the steam wand 200. When the steam wand 200 is immersed in the beverage, the beverage will also remain on the outer surface of the steam wand 200. If the beverage remaining on the steam wand 200 is not cleaned in time, bacteria may grow, thereby affecting the use of the steam wand 200.

[0041] The cleaning unit is connected to the steam wand 200 to clean the internal channel of the steam wand 200. The fluid medium is supplied to the internal channel of the steam wand 200 through the cleaning unit. The fluid medium can be steam or clean water, and the internal channel of the steam wand 200 can be cleaned to clean the steam wand 200 by flushing the residual beverage in the internal channel of the steam wand 200. The fluid medium after flushing will be discharged from the internal channel of the steam wand 200 to the outside. The cleaning unit can be a fluid system provided by the device equipped with the steam wand, such as a hot water pipeline or a steam generating component of a coffee machine. The cleaning unit can also be a separately provided fluid system, which is not limited by the present application.

[0042] In some embodiments, the cleaning unit is a steam generating assembly in the device body 20, and the steam generating assembly is used to generate steam, and the steam output by the steam generating assembly is used as a fluid medium for cleaning the steam wand 200 to clean the internal channel of the steam wand 200. For example, the steam channel 210 of the steam wand 200 is connected to the steam generating assembly, so that steam is injected into the steam channel 210 through the steam generating assembly, and then the steam is discharged through the outlet end of the steam wand 200.

[0043] In some embodiments, the cleaning unit is a water supply component in the device body 20, and the water supply component is used in the device body 20 to provide clean water, and the water output by the water supply component is used as a fluid medium for cleaning the steam rod 200 to clean the internal channel of the steam rod 200. For example, the steam channel 210 of the steam rod 200 is connected to the water supply component, so that clean water is supplied to the steam channel 210 through the water supply component to clean the steam channel 210.

[0044] In some embodiments, the steam generating assembly and the water supply assembly can also be used for cleaning the steam wand 200 at the same time, that is, the steam generating assembly and the water supply assembly together form a cleaning unit. When the cleaning unit is the steam generating assembly and / or the water supply assembly in the device body 20, the steam generating assembly, the water supply assembly, and the switch device 100 are all electrically connected to the controller in the device body 20, and the steam wand 200 is cleaned under the control of the controller.

[0045] In some embodiments, the cleaning unit can also be a component independent of the device body 20. The cleaning unit includes a controller and a water tank and a water pump connected by a pipeline, and the switch device 100 and the water pump are both electrically connected to the controller. When the steam rod 200 is operably acted on the switch device 100, the controller receives a signal from the switch device 100, and then the controller starts the water pump, and the water pump pumps the clean water in the water tank to the internal channel of the steam rod 200 through the pipeline for cleaning. In some embodiments, the controller of the cleaning unit is electrically connected to the controller in the device body 20, and the steam rod cleaning is realized under the control of the controller. In some embodiments, the cleaning unit may also only include a water tank and a water pump connected by a pipeline, and the water pump is electrically connected to the controller in the device body 20, and pumps water into the steam rod 200 under the control of the controller.

[0046] The switch device 100 is triggered by the steam wand 200. The steam wand 200 can be operably acted on the switch device 100, so that the cleaning unit responds to the switch device 100, thereby supplying the fluid medium to the internal channel of the steam wand 200 to flush the beverage remaining in the internal channel of the steam wand 200, and realize the self-cleaning of the steam wand 200. It should be understood that the switch device 100 is set at a fixed position, so that the switch device 100 can only be triggered when the steam wand 200 is moved to a certain area, such as the installation position of the switch device 100. Therefore, the fluid medium discharged from the steam wand 200 will be discharged to a certain fixed area, that is, by setting the steam wand 200 to be operably acted on the switch device 100, on the one hand, the self-cleaning of the steam wand 200 is realized, and the convenience is improved; on the other hand, the fixed-point discharge of the fluid medium after flushing the steam wand 200 is realized, so as to facilitate the treatment of the flushed fluid medium.

[0047] See also Figure 2and Figure 3 In some embodiments, the switch device 100 includes a first induction member 110 and a second induction member 120. The first induction member 110 and the second induction member 120 are coupled, which may be magnetic coupling, photoelectric coupling or mechanical structure coupling, which is not limited in this application. In some embodiments, the first induction member 110 is a magnet, and the second induction member 120 is a reed switch, and the cleaning signal is triggered by magnetic coupling.

[0048] The steam rod 200 can be operably acted on the first induction member 110, and the second induction member 120 is installed on the device body 20. Since the cleaning unit responds to the switch device 100, the cleaning unit is electrically connected to the switch device 100, and the switch device 100 is set to be a coupled first induction member 110 and a second induction member 120, and the second induction member 120 is an electrical connection part of the switch device 100. The second induction member 120 is arranged on the device body 20, so that the electrical connection harness between the second induction member 120 and the cleaning unit is located inside the device body 20, which is convenient for wiring. The first induction member 110 is located on the outer surface of the device body 20 or is relatively independent of the device body 20. By allowing the steam rod 200 to act on the first induction member 110, the fluid medium discharged from the steam rod 200 is prevented from contacting the electrical connection part of the switch device 100, thereby reducing the influence of the fluid medium discharged from the steam rod 200 on the switch device 100.

[0049] See also Figure 1 and Figure 2 In some embodiments, the steam wand cleaning mechanism 10 further includes a steam receiving station 300, which is convenient for placing a container for beverages, and the steam wand 200 can be operably extended into the container, so as to operate the steam wand 200 to spray steam into the beverage in the container. In some embodiments, the first sensing element 110 is movably arranged at the steam receiving station 300, so that the steam wand 200 can operably act on the first sensing element 110, so that the first sensing element 110 moves to a position where it can be coupled with the second sensing element 120, so as to start the cleaning unit through the second sensing element 120. Since the steam wand 200 needs to be extended into the container when in use, the area where the steam receiving station 300 is located is equivalent to the operable area of ​​the steam wand 200. By arranging the first sensing element 110 at the steam receiving station 300, the use operation and self-cleaning operation of the steam wand 200 are completed in the same operation area, which is convenient to use.

[0050] In order to facilitate the collection of the fluid medium discharged from the steam wand 200, please refer to Figure 3In some embodiments, the steam receiving station 300 is provided with a cleaning tank 301, and the steam wand 200 is operable to extend into the cleaning tank 301 to discharge the cleaned fluid medium into the cleaning tank 301. The cleaning tank 301 collects the fluid medium discharged by the steam wand 200 to prevent the fluid medium discharged by the steam wand 200 from dispersing to the surrounding environment and affecting the surrounding environment. After the steam wand 200 extends into the cleaning tank 301, it can not only discharge the cleaned fluid medium, but also act on the first sensor 110. In other words, the steam wand 200 can trigger the coupling of the first sensor 110 and the second sensor 120 only after extending into the cleaning tank 301, thereby preventing the first sensor 110 and the second sensor 120 from being triggered by mistake, causing the fluid medium to be discharged outside the cleaning tank 301, polluting the environment or scalding people. In addition, when the steam rod 200 discharges the fluid medium into the cleaning tank 301, the discharged fluid medium will splash inside the cleaning tank 301 under the obstruction of the tank wall of the cleaning tank 301. When the splashed fluid medium falls on the outer surface of the steam rod 200, the outside of the outlet end of the steam rod 200 can also be cleaned.

[0051] See also Figure 3 In some embodiments, the switch device 100 further includes a transmission member 130, which is movably disposed in the steam receiving station 300, and one end of the transmission member 130 extends into the cleaning tank 301. The first induction member 110 is installed on the other side of the transmission member 130, and is encapsulated inside the steam receiving station 300, away from the cleaning tank 301, and the first induction member 110 moves with the transmission member 130. The steam rod 200 acts on the first induction member 110 through the transmission member 130. By setting the transmission member 130, the steam rod 200 is prevented from directly contacting the first induction member 110, and the influence of the cleaning fluid medium on the first induction member 110 is reduced.

[0052] In some embodiments, the first induction member 110 is a magnet, the second induction member 120 is a reed switch, and the shell of the steam wand 200 is a metal material. By providing the transmission member 130, the steam wand 200 is prevented from directly contacting the first induction member 110, and the effect of the shell of the steam wand 200 on the coupling sensitivity between the first induction member 110 and the second induction member 120 can be reduced, so as to avoid the switch device 100 being unable to start or mistakenly starting the cleaning unit, thereby affecting the cleaning effect of the steam wand.

[0053] In order to reduce the amount of fluid discharged from the steam wand 200 entering the steam receiving station 300, which is inconvenient to clean, please refer to Figure 3In some embodiments, the steam receiving station 300 is provided with a seal 310, which is arranged in the wall of the cleaning tank 301, and the end of the transmission member 130 away from the first induction member 110 passes through the seal 310 and extends into the cleaning tank 301. In this way, the seal 310 ensures the setting requirements of the transmission member 130 while preventing the fluid medium discharged from the steam rod 200 from entering the interior of the steam receiving station 300 and flowing to the first induction member 110, thereby affecting the first induction member 110. In some embodiments, the bottom of the cleaning tank 301 is inclined, and a drainage hole (not shown in the figure) is arranged at the lowest point of the bottom of the tank, so that the fluid medium discharged from the steam rod 200 to the cleaning tank 301 is discharged to the outside of the cleaning tank 301 through the drainage hole, and the drainage of the fluid medium is promoted by setting the bottom of the cleaning tank 301 inclined.

[0054] See also Figure 3 In some embodiments, the steam receiving station 300 is further provided with a reset member 320, which acts on the transmission member 130 so that after the steam rod 200 is separated from the transmission member 130, the transmission member 130 is maintained at the initial position, thereby disconnecting the coupling between the first induction member 110 and the second induction member 120. When the steam rod 200 acts on the transmission member 130, the transmission member 130 drives the first induction member 110 to move to a position coupled with the second induction member 120, triggering a cleaning signal, and the cleaning unit provides a fluid medium to the internal channel of the steam rod; after the cleaning is completed, the steam rod 200 is removed, and the transmission member 130 is reset under the action of the reset member 320, driving the first induction member 110 to leave the position coupled with the second induction member 120, thereby realizing the reset of the first induction member 110. The reset member 320 can be a spring, rubber or other elastic component, which is not limited in the embodiment of the present application. In order to prevent the fluid medium discharged from the steam rod 200 from affecting the reset member 320, the reset member 320 can be arranged inside the steam receiving station 300.

[0055] See also Figure 3 In some embodiments, in order to facilitate the arrangement of the first sensing member 110, the transmission member 130, the sealing member 310 and the reset member 320, an active cavity 302 connected to the cleaning tank 301 is provided inside the steam receiving station 300, the first sensing member 110 can be movably arranged in the active cavity 302, the sealing member 310 is arranged at the connection between the active cavity 302 and the cleaning tank 301, the transmission member 130 is passed through the sealing member 310, and one end of the reset member 320 is pressed against the transmission member 130, and the other end is pressed against the cavity wall of the active cavity 302 for connection.

[0056] The steam receiving station 300 may be a part of the equipment body 20 or may be independent of the equipment body 20. The number of steam receiving stations 300 is not limited to one, and multiple steam receiving stations 300 may be provided according to actual use needs. Figure 4 and Figure 5 In some embodiments, the steam receiving station 300 is independent of the device body 20. In order to facilitate the disassembly and assembly of the steam receiving station 300 on the device body 20, mutually attractive magnets and concave-convex positioning structures are provided on the steam receiving station 300 and the device body 20. When the steam receiving station 300 is installed on the device body 20, the positioning structure makes the position of the steam receiving station 300 and the device body 20 relatively fixed. At the same time, the steam receiving station 300 is adsorbed and fixed on the device body 20 by the magnet.

[0057] See also Figure 4 and Figure 5 In some embodiments, a convex part 330 and a first magnet 340 are provided on one side of the surface of the steam receiving station 300 connected to the device body 20. Correspondingly, a concave part 21 cooperating with the convex part 330 and a second magnet 22 mutually attracted to the first magnet 340 are provided on the surface of the device body 20 connected to the steam receiving station 300. In this way, mutually attractive magnets and concave-convex cooperating positioning structures are provided on the steam receiving station 300 and the device body 20. In some embodiments, the steam receiving station 300 can also be provided with a snap connection with the device body 20, so that the steam receiving station 300 can be installed and fixed on the device body 20 through the snap structure, and the embodiments of the present application are not limited to this.

[0058] See also Figure 2 and Figure 6 In some embodiments, the steam wand 200 includes a steam pipe 230 and a steam channel 210, and the steam channel 210 is located in the tube cavity of the steam pipe 230, thereby forming a double-layer structure of the steam wand 200. The steam channel 210 is an internal channel of the steam wand 200, and the steam flows through the steam channel 210, so the tube wall temperature of the steam channel 210 is relatively high. By sleeve-arranging the steam pipe 230 outside the steam channel 210, a certain interval is formed between the steam pipe 230 and the steam channel 210 for heat insulation, so as to prevent the operator from directly contacting the steam channel 210 and being scalded. In some embodiments, the steam wand 200 includes a steam pipe 230, a steam channel 210 and an air channel, and the steam channel 210 and the air channel are both located in the tube cavity of the steam pipe 230, and the steam channel 210 and the air channel are both internal channels of the steam wand 200.

[0059] In order to facilitate the operation of the steam wand 200 installed on the device body 20, in some embodiments, the steam wand 200 is movably installed on the device body 20. Specifically, the steam wand 200 can be rotatably connected or slidably matched with the device body 20, so that the steam wand 200 can be moved on the device body 20 by operating the steam wand 200, extended into the container, extended into the cleaning tank 301, or drive the first sensing element 110 to move.

[0060] See also Figure 1 and Figure 6 In some embodiments, the steam wand 200 is provided with a universal joint 220, which is rotatably mounted on the device body 20.

After the upper bracket 221 and the ball seat 223 are connected, the two enclose a ball cavity 225. The ball core 222 is rotatably arranged in the ball cavity 225. At least one of the upper bracket 221, the ball core 222 and the ball seat 223 is connected to the steam pipe 230, and at least one of them is connected to the device body 20, so that the steam pipe 230 can be flexibly rotated on the device body 20. In some embodiments, the steam pipe 230 is fixedly connected to the upper bracket 221 and / or the ball seat 223, and the ball core 222 is connected to the device body 20. The rotation of the ball core 222 in the ball cavity 225 realizes the rotation of the steam wand 200 on the device body 20. In some embodiments, a steam pipe 230 may be provided to be connected to the ball core 222, and the upper bracket 221 and / or the ball seat 223 may be connected to the device body 20. The rotation of the ball core 222 in the ball cavity 225 may also realize the rotation of the steam rod 200 on the device body 20.

[0062] In some embodiments, the steam pipe 230 is connected to the ball core 222, and the upper bracket 221 and the ball seat 223 are both connected to the device body 20. Figure 6 The lower end of the ball core 222 is provided with a connecting portion 222b, which is threadedly connected to the steam pipe 230. The ball core 222 is a hollow structure, and is provided with a through channel 222a. The steam channel 210 extends out of the universal joint 220 and into the equipment body 20 through the through channel 222a to communicate with the cleaning unit in the equipment body 20.
