[0048] Currently, when a beverage machine for making beverages (e.g., a milk cap machine, a milk foam machine, etc.) makes different types of beverages, it is necessary to adjust the mixing ratio of air and dairy products (fresh milk, cream), and after adding the raw materials, it is also necessary to debug the beverage machine and readjust the mixing ratio of air and dairy products. The existing air adjustment structure is generally installed inside the beverage machine together with the mixing pump, making it inconvenient to manually adjust the mixing ratio of air and dairy products.

[0049] Embodiments of the present disclosure provide a beverage machine for making beverages. In the embodiments of the present disclosure, the beverage machine can be, but is not limited to, a milk cap machine or a milk foam machine.

The upper cover 11 and the main body 12 can enclose an installation space 100, and at least part of the upper cover 11 can be detachable from the main body 12 to expose the installation space 100. For example, the upper cover 11 can be rotationally connected to the main body 12, and by rotating relative to the main body 12, the installation space 100 can be exposed or covered.

[0051] The discharging device 20 is arranged on the housing assembly 10. The discharging device 20 includes a feeding member 21, an air inlet assembly 22, a discharging mechanism 23 and a mixing mechanism 24. Among them, the mixing mechanism 24 can be installed in the installation space 100 and partially penetrates through the main body 12 to be connected with the discharging mechanism 23 located outside the main body 12. The beverage machine further includes at least one material bin 30 installed in the installation space 100. The material bin 30 is configured to store at least one raw material. In the embodiment of the present disclosure, the material bin 30 stores dairy products, such as fresh milk or cream. When the installation space 100 is in an exposed state, it is convenient to add raw materials to the material bin 30. When the installation space 100 is in a covered state, it can prevent external impurities and dust from falling into the material bin 30. In addition, the beverage machine further includes a heating device and / or a cooling device, which are configured to heat and / or refrigerate the raw materials.

[0052] The beverage machine further includes a decorative shell 40. The decorative shell 40 is arranged on the main body 12 and sleeved outside the discharging mechanism 23. The decorative shell 40 is provided with a discharging port 200. The decorative shell 40 can improve the overall aesthetics of the beverage machine. In addition, in some embodiments, the beverage machine may not include the decorative shell 40, and the discharging mechanism 23 can be directly exposed.

[0053] As Figure 4 shown, the feeding member 21 is provided with a feeding port 301, an air inlet 302 and a feeding channel 303. The feeding port 301 is configured to allow dairy products to enter the feeding channel 303, and the air inlet 302 is configured to allow air to enter the feeding channel 303. The air inlet assembly 22 is communicated with the air inlet 302 through a pipeline (not shown), and the relative position between the air inlet assembly 22 and the air inlet 302 can be adjusted by changing the extension dimension of the pipeline. The air inlet assembly 22 is configured to be able to adjust the amount of air entering the air inlet 302. In the embodiment of the present disclosure, the feeding member 21 is arranged on the mixing mechanism 24 and can be installed in the installation space 100 along with the mixing mechanism 24. The feeding port 301 can be connected to a feeding pipe 25 and communicated with the material bin 30 through the feeding pipe 25. The mixing mechanism 24 is respectively communicated with the feeding channel 303 and the discharging mechanism 23. The mixing mechanism 24 is configured to be able to mix dairy products and air into a mixture and discharge it from the discharging mechanism 23. The air inlet assembly 22 is arranged on the main body 12 and at least part (the operating part) is exposed outside the main body 12 to facilitate the hand to adjust the amount of air entering the air inlet 302, and further facilitate the adjustment of the mixing ratio of air and dairy products. The pipeline can be a rigid pipeline or a flexible pipeline. It can be understood that in other embodiments, the air inlet assembly 22 may not be arranged on the main body 12, and can be communicated with the air inlet 302 through a flexible pipeline and placed outside the housing assembly 10, so that the air inlet assembly 22 is only connected to the feeding member 21 through a flexible pipeline, and its position can be arbitrarily changed within the limit range of the flexible pipeline, further facilitating the hand to operate the air inlet assembly 22 to adjust the amount of air entering the air inlet 302.

[0054] In summary, the implementation of the disclosed embodiment will have the following beneficial effects: the discharging device 20 of the above-mentioned scheme is applied to the beverage machine, which can conveniently adjust the mixing ratio of air and dairy products. Specifically, the discharging device 20 includes a feeding piece 21, an air inlet assembly 22, a discharging mechanism 23 and a mixing mechanism 24. Among them, the feeding piece 21 is provided with a feeding port 301, an air inlet 302 and a feeding channel 303. The feeding port 301 is configured to allow dairy products to enter the feeding channel 303, and the air inlet 302 is configured to allow air to enter the feeding channel 303. The mixing mechanism 24 is respectively connected to the feeding channel 303 and the discharging mechanism 23, and the mixing mechanism 24 is configured to be able to mix the dairy product and air into a mixture, and discharge it from the discharging mechanism 23. The air intake component 22 is connected to the air inlet 302 through a pipeline, and the relative position of the air intake component 22 and the air inlet 302 can be adjusted by changing the extension size of the pipeline. In this way, by adjusting the relative position of the air intake component 22 and the air inlet 302, at least the control part of the air intake component 22 can be installed on the outside of the beverage machine for manual operation, thereby facilitating the adjustment of the mixing ratio of air and dairy products.

[0055] In the exemplary embodiment, please combine Figures 1 to 3 , the air inlet assembly 22 includes a driving member 221, a valve body 222 and a valve core (not shown). The valve body 222 is provided with an air inlet hole (not shown) and an air outlet hole 400. The air outlet hole 400 is connected between the pipeline and the air inlet hole. The valve core is movably mounted on the valve body 222. The driving member 221 is arranged on the valve core, and can drive the valve core to move relative to the valve body 222 to adjust the connection area between the air inlet hole and the air outlet hole 400. In the embodiment of the present disclosure, the driving member 221 is a knob, which is exposed on the outside of the main body 12 and can rotate relative to the main body 12. The valve body 222 is fixed to the main body 12. The knob can be rotated relative to the main body 12 by manual drive, and then can drive the valve core to rotate relative to the valve body 222 to adjust the connection area between the air inlet hole and the air outlet hole 400. The valve core can be provided with a through hole, and the area of ​​the through hole facing the air inlet and the air outlet 400 can be adjusted by rotating the valve core relative to the valve body 222, thereby adjusting the connection area between the air inlet and the air outlet 400, and changing and adjusting the amount of air entering the air inlet 302. The driving of the valve core by the knob can be a stepless drive or a gear drive. It can be understood that in other embodiments, the driving member 221 can also be a lever structure, and the lever is moved by hand to drive the valve core to rotate relative to the valve body 222. In addition, in some embodiments, through holes of different diameters can be provided on the valve core, and the valve core is driven to move linearly relative to the valve body 222, so that the through holes of different diameters are connected between the air inlet and the air outlet 400, so as to change the connection area between the air inlet and the air outlet 400, and change and adjust the amount of air entering the air inlet 302.

[0056] In the exemplary embodiment, please combine Figures 4 to 6 The discharging device 20 further includes a first one-way valve 211 and a second one-way valve 212. The first one-way valve 211 is disposed on the feeding member 21, between the feeding port 301 and the feeding channel 303, and the first one-way valve 211 is configured to prevent the material in the feeding channel 303 from flowing back to the feeding port 301. The second one-way valve 212 is disposed on the feeding member 21, between the air inlet 302 and the feeding channel 303, and the second one-way valve 212 is configured to prevent the air from flowing back to the air inlet 302. The material is a product obtained by premixing the dairy product and the air in the feeding channel 303. When the mixing mechanism 24 mixes the dairy product and the air, a pressure difference is easily formed between the inside and the outside of the mixing mechanism 24. When the mixing mechanism 24 stops working, due to the existence of the pressure difference, a backflow phenomenon is easily caused. The first one-way valve 211 can prevent the pre-mixed product of the dairy product and the air from flowing back to the feed port 301 and then entering the silo 30 to pollute the raw materials. The second one-way valve 212 can prevent the pre-mixed product of the dairy product and the air from flowing back to the air inlet 302, blocking the air inlet 302 or even entering the air inlet assembly 22 through the pipeline, causing pollution to the air inlet assembly 22, making it impossible for the air inlet assembly 22 to accurately control the amount of air entering the air inlet 302.

[0057] In the disclosed embodiment, the first one-way valve 211 includes a first fixed portion 2111 and a first deformable portion 2112 disposed on the first fixed portion 2111. The first fixed portion 2111 may be made of a hard material so as to be fixedly connected to the feed member 21. The first fixed portion 2111 is provided with a first flow hole. The first deformable portion 2112 may be made of an elastomeric material and has a first normally closed opening. The dairy product may enter the first deformable portion 2112 through the first flow hole, and prop up the first normally closed opening to enter the feed channel 303. On the contrary, the product obtained by premixing the dairy product and the air in the feed channel 303 cannot enter the first deformable portion 2112, and therefore cannot prop up the first normally closed opening to enter the feed port 301, thereby preventing the material in the feed channel 303 from flowing back to the feed port 301.

[0058] The second one-way valve 212 includes a second fixed portion 2121 and a second deformable portion 2122 disposed on the second fixed portion 2121. The second fixed portion 2121 may be made of a hard material so as to be fixedly connected to the feed member 21. The second fixed portion 2121 is provided with a second flow hole. The second deformable portion 2122 may be made of an elastomeric material and has a second normally closed opening. Air may enter the second deformable portion 2122 through the second flow hole, and prop up the second normally closed opening to enter the feed channel 303. On the contrary, the product obtained by premixing the dairy product and the air in the feed channel 303 cannot enter the second deformable portion 2122, and therefore cannot prop up the second normally closed opening to enter the air inlet 302, thereby preventing the material in the feed channel 303 from flowing back to the air inlet 302.

[0059] The feed member 21 is also provided with a first joint assembly 213 and a second joint assembly 214. The first joint assembly 213 is provided at the feed port 301 and connected to the feed pipe 25, so that the feed port 301 is communicated with the feed pipe 25. The second joint assembly 214 is provided at the air inlet 302 and connected to the pipeline, so that the air inlet 302 is communicated with the pipeline, and the other end of the pipeline can be communicated with the air outlet 400 through the third joint assembly.

[0060] The first joint assembly 213 is disposed at the feed inlet 301 and can also clamp the first fixing portion 2111 to the feed piece 21. The second joint assembly 214 is disposed at the feed inlet 301 and can also clamp the second fixing portion 2121 to the feed piece 21.

[0061] In the exemplary embodiment, please combine Figure 3 and Figures 7 to 10 The mixing mechanism 24 includes a mixing pump 241 and a drainage member 242. The drainage member 242 is provided with a first drainage channel 501 and a second drainage channel 502. The first drainage channel 501 is connected between the feed channel 303 and the mixing pump 241. The second drainage channel 502 is connected between the mixing pump 241 and the discharging mechanism 23. The mixing pump 241 can mix the dairy product and the air into a mixture, and discharge it into the second drainage channel 502. In this way, the arrangement of the drainage member 242 can facilitate the mixing pump 241 to communicate with the feed member 21 and the discharging mechanism 23, facilitate the dairy product and the air to enter the mixing pump 241, and facilitate the mixture to be discharged from the mixing pump 241 into the discharging mechanism 23.

[0062] The first drainage channel 501 is provided with a first valve core assembly 2421, which is configured to prevent the mixture from flowing back into the feed channel 303. The second drainage channel 502 is provided with a second valve core assembly 2422, which is configured to prevent the mixture from flowing back into the mixing pump 241. Similarly, when the mixing pump 241 mixes dairy products and air, it is easy to form a pressure difference between the inside and outside of the mixing pump 241. When the mixing pump 241 stops working, due to the existence of the pressure difference, it is easy to cause the occurrence of a backflow phenomenon. Through the setting of the first valve core assembly 2421, the mixture can be prevented from flowing back into the feed channel 303, and when the mixing pump 241 is turned on, the mixture can also be prevented from flowing back into the feed channel 303. And through the setting of the second valve core assembly 2422, the mixture discharged from the mixing pump 241 can be prevented from flowing back into the mixing pump 241, causing pollution to the inside of the mixing pump 241.

[0063] After the mixing pump 241 is turned on, it can generate suction. Under the action of the suction, the dairy product enters the feeding part 21 through the feeding pipe 25, and then enters the feed channel 303 through the first one-way valve 211. Correspondingly, air enters the air intake assembly 22 through the air intake hole, and enters the feeding part 21 through the air outlet hole 400 and the pipeline, and then enters the feed channel 303 through the second one-way valve 212. The dairy product and air are pre-mixed in the feed channel 303 and then enter the first drainage channel 501. After passing through the first valve core assembly 2421, they enter the mixing pump 241 for mixing to obtain a mixture. The mixture is driven by the mixing pump 241 into the second drainage channel 502, and after passing through the second valve core assembly 2422, it is discharged from the drainage part 242. The drainage part 242 is provided with a delivery pipeline 26 communicated with the discharging mechanism 23. The mixture is driven by the mixing pump 241 to pass through the second valve core assembly 2422 and enter the delivery pipeline 26, and finally is discharged from the discharging mechanism 23. After the beverage production is completed, the mixing pump 241 stops working, and the second valve core assembly 2422 can prevent the mixture from flowing back into the mixing pump 241.

[0064] In an exemplary embodiment, such as Figure 9As shown, the first spool assembly 2421 includes a first elastic member 24211 and a first plug member 24212. The first elastic member 24211 and the first plug member 24212 are received in the first drainage channel 501. The first elastic member 24211 is elastically clamped between the drainage member 242 and the first plug member 24212, and can drive the first plug member 24212 to abut against the drainage member 242 to seal one end of the feed channel 303 close to the mixing pump 241. Driven by dairy products and / or air, the first plug member 24212 compresses the first elastic member 24211 to generate a driving force for resetting the first plug member 24212, and conducts the feed channel 303 and the mixing pump 241. In this way, when the mixing pump 241 stops working and cannot generate suction, the dairy products and air cannot enter the first drainage channel 501 after being premixed in the feed channel 303, and the first plug member 24212 can always abut against the drainage member 242 to seal one end of the feed channel 303 close to the mixing pump 241.

[0065] After the mixing pump 241 is turned on, the dairy products and air can drive the first plug member 24212 under the action of suction after being premixed in the feed channel 303. The first elastic member 24211 is compressed under the drive of the first plug member 24212 to generate a driving force for resetting the first plug member 24212, and conducts the feed channel 303 and the mixing pump 241. In this way, after the mixing pump 241 is turned on, the first plug member 24212 can move away from one end of the feed channel 303 close to the mixing pump 241, so that the feed channel 303 and the mixing pump 241 are conducted, and the dairy products and air can enter the mixing pump 241 for mixing. Thus, when the mixing pump 241 is turned on or off, the first spool assembly 2421 can automatically switch the conduction or disconnection of the feed channel 303 and the mixing pump 241, ensuring that the dairy products and air can smoothly enter the mixing pump 241 when a mixture needs to be made, and after the beverage production is completed, the feed channel 303 and the mixing pump 241 can be automatically disconnected to prevent the mixture from flowing back to the feed channel 303.

[0066] In an exemplary embodiment, as Figure 9 shown, the drainage member 242 is provided with a first narrowing through hole 503. The first narrowing through hole 503 gradually narrows from the first drainage channel 501 to the feed channel 303 to facilitate guiding the first plug member 24212 to the feed channel 303 and ensuring the stability of sealing one end of the feed channel 303 close to the mixing pump 241.

[0067] In an exemplary embodiment, as Figure 8 and Figure 9As shown, the drainage member 242 has a pressing plate 2423. The pressing plate 2423 can move relative to the drainage member 242 to adjust the compression amount of the first elastic member 24211, which can ensure the magnitude of the abutting force exerted by the first blocking member 24212 on the drainage member 242, ensure the sealing performance of the first blocking member 24212 at one end of the feed channel 303 close to the mixing pump 241, and ensure that after the mixing pump 241 is normally started, dairy products and air can easily compress the first elastic member 24211 by the first blocking member 24212 under the action of suction force, so that the dairy products and air can smoothly enter the mixing pump 241.

[0068] In an exemplary embodiment, as Figure 10 shown, the second valve core assembly 2422 includes a second elastic member 24221 and a second blocking member 24222. The second elastic member 24221 and the second blocking member 24222 are received in the second drainage channel 502. The second elastic member 24221 is elastically clamped between the drainage member 242 and the second blocking member 24222, and can drive the second blocking member 24222 to abut against the drainage member 242 to seal one end of the mixing pump 241 close to the discharging mechanism 23. The second blocking member 24222 compresses the second elastic member 24221 under the drive of the mixture to generate a driving force for resetting the second blocking member 24222, and makes the mixing pump 241 and the discharging mechanism 23 communicate. In this way, when the mixing pump 241 stops working and cannot drive the mixture, the mixture cannot enter the second drainage channel 502, and the second blocking member 24222 can always abut against the drainage member 242 to seal one end of the mixing pump 241 close to the discharging mechanism 23.

[0069] After the mixing pump 241 is started, the mixture can drive the second blocking member 24222 under the drive of the mixing pump 241. The second elastic member 24221 is compressed under the drive of the second blocking member 24222 to generate a driving force for resetting the second blocking member 24222, and makes the discharging mechanism 23 and the mixing pump 241 communicate. In this way, after the mixing pump 241 is started, the second blocking member 24222 can move away from one end of the mixing pump 241 close to the discharging mechanism 23, so that the discharging mechanism 23 and the mixing pump 241 communicate, and the mixture can enter the discharging mechanism 23 and be discharged. Thus, the second valve core assembly 2422 can automatically switch the communication or disconnection between the discharging mechanism 23 and the mixing pump 241 when the mixing pump 241 is started or stopped, ensuring that when the mixture needs to be made, the mixture can smoothly discharge from the discharging mechanism 23, and after the beverage production is completed, the discharging mechanism 23 and the mixing pump 241 can automatically disconnect to prevent the mixture from flowing back to the mixing pump 241.

[0070] In an exemplary embodiment, as Figure 10As shown, the drainage member 242 is provided with a second narrowing through hole 504, and the second narrowing through hole 504 gradually narrows from the second drainage channel 502 towards the mixing pump 241, so as to facilitate guiding the second blocking member 24222 towards the mixing pump 241 and ensure the stability of the sealing of the end of the mixing pump 241 close to the discharging mechanism 23.

[0071] In an exemplary embodiment, as Figure 8 and Figure 10 shown, the drainage member 242 has a pressing plate 2423, and the pressing plate 2423 can move relative to the drainage member 242 to adjust the compression amount of the second elastic member 24221, which can ensure the magnitude of the abutting force of the second blocking member 24222 acting on the drainage member 242, ensure the sealing performance of the second blocking member 24222 on the end of the mixing pump 241 close to the discharging mechanism 23, and ensure that after the mixing pump 241 is normally started, the mixture can easily compress the second elastic member 24221 through the second blocking member 24222 under the drive of the mixing pump 241, so that the mixture can smoothly enter the discharging mechanism 23.

[0072] In the embodiment of the present disclosure, the drainage member 242 is provided with a mounting groove, and the pressing plate 2423 can be mounted in the mounting groove and match with the mounting groove to ensure the sealing performance of the mounting groove. The pressing plate 2423 can move relative to the drainage member 242 and act on the first valve core assembly 2421 and the second valve core assembly 2422 at the same time to adjust the compression amounts of the first elastic member 24211 and the second elastic member 24221. The pressing plate 2423 is provided with two communication holes 505 to facilitate the communication between the mixing pump 241 and the first drainage channel 501 and the second drainage channel 502.

[0073] In the embodiment of the present disclosure, both the first elastic member 24211 and the second elastic member 24221 are springs. Both the first blocking member 24212 and the second blocking member 24222 are spherical, so that the first blocking member 24212 and the second blocking member 24222 can move smoothly relative to the drainage member 242, avoiding the jamming phenomenon of the first blocking member 24212 and the second blocking member 24222, and ensuring the stability of the sealing of the end of the feeding channel 303 close to the mixing pump 241 and the end of the mixing pump 241 close to the discharging mechanism 23. The cross-sections of the first drainage channel 501 and the second drainage channel 502 can be circular, square or elliptical, etc. The first blocking member 24212 can be spaced from the inner wall of the drainage member 242 to form the first drainage channel 501 to facilitate the movement of the first blocking member 24212 relative to the drainage member 242. The second blocking member 24222 can be spaced from the inner wall of the drainage member 242 to form the second drainage channel 502 to facilitate the movement of the second blocking member 24222 relative to the drainage member 242.

[0074] On one side of the second drainage channel 502 away from the mixing pump 241, a first clamping interface 506 is connected, so as to facilitate the clamping and connection of the drainage member 242 and the delivery pipeline 26. It can be understood that in other embodiments, the first plug member 24212 and the second plug member 24222 can also be cylindrical, frustum-shaped, prismatic or pyramid-shaped, etc., as long as they can match the end of the feed channel 303 close to the mixing pump 241 and the end of the mixing pump 241 close to the discharging mechanism 23.

[0075] In an exemplary embodiment, please also refer to Figure 3 and Figure 11 and Figure 12 The discharging mechanism 23 includes a housing 231 and a third valve core assembly 232. The housing 231 is provided with a discharging channel 600. The third valve core assembly 232 is disposed in the housing 231. At least a part of the third valve core assembly 232 is received in the discharging channel 600. The third valve core assembly 232 is configured to be able to conduct or disconnect the discharging channel 600. The mixing mechanism 24 is connected to the discharging mechanism 23 through the discharging channel 600. In this way, after the beverage production is completed, the discharging channel 600 can be disconnected by the third valve core assembly 232 to prevent the mixture from entering the discharging channel 600, so as to avoid the phenomenon that the residue in the discharging channel 600 continuously discharges and causes the residue to continuously drip from the discharging port 200.

[0076] The discharging channel 600 includes a feeding end 601 and a discharging end 602 that are in communication with each other. The third valve core assembly 232 includes a third elastic member 2321 and a third plug member 2322. The third elastic member 2321 and the third plug member 2322 are received in the discharging channel 600. The third elastic member 2321 is elastically clamped between the housing 231 and the third plug member 2322, and can drive the third plug member 2322 to abut against the housing 231 to seal the feeding end 601, so as to disconnect the feeding end 601 and the discharging end 602. In this way, when the mixing mechanism 24 does not provide a mixture to the discharging mechanism 23, the third plug member 2322 can always abut against the housing 231 to seal the feeding end 601.

[0077] The mixing mechanism 24 can discharge the mixture into the feeding end 601. Driven by the mixture, the third plug 2322 compresses the third elastic member 2321 to generate a driving force for resetting the third plug 2322, and makes the feeding end 601 and the discharging end 602 communicate. In this way, when the mixing mechanism 24 provides the mixture to the discharging mechanism 23, it can drive the third plug 2322 to move away from the feeding end 601, so that the discharging flow channel 600 is in a communicating state, and the mixture can enter the discharging flow channel 600 and be discharged. Thus, when the mixing mechanism 24 is opened or closed, the third valve core assembly 232 can automatically switch the discharging flow channel 600 between communication and disconnection, ensuring that when the mixture needs to be made, the mixture can smoothly discharge from the discharging flow channel 600. After the beverage production is completed, the discharging flow channel 600 can automatically disconnect to prevent the mixture from entering the discharging flow channel 600, so as to avoid the phenomenon that the residue in the discharging flow channel 600 continuously discharges and drips from the discharging port 200.

[0078] The housing 231 includes a discharging pipe 2311 and a plug 2312. The discharging flow channel 600 further includes a flow channel section 603, and the flow channel section 603 penetrates through the discharging pipe 2311 along the first direction and forms a feeding end 601 and an opening 604 on the discharging pipe 2311. The discharging end 602 is arranged on the circumferential outer side of the flow channel section 603 and communicates with the flow channel section 603. Among them, the first direction is parallel to Figure 12 the direction indicated by the arrow X.

[0079] The plug 2312 is sealingly installed on the opening 604 and can move relative to the discharging pipe 2311 along the opening 604 to adjust the compression amount of the third elastic member 2321, which can ensure the magnitude of the abutting force of the third plug 2322 acting on the discharging pipe 2311, ensure the sealing performance of the third plug 2322 to the feeding end 601, and ensure that under the normal driving of the mixture by the mixing mechanism 24, the mixture can easily compress the third elastic member 2321 through the third plug 2322, so that the mixture can smoothly enter the discharging flow channel 600 in a communicating state. The plug 2312 can match the opening 604 to ensure the sealing performance of the opening 604 and prevent the mixture from overflowing from the opening 604. The plug 2312 can be connected to the discharging pipe 2311 by means of threads or interference fit so as to be able to move relative to the discharging pipe 2311 and adjust the compression amount of the third elastic member 2321.

[0080] In the embodiments of the present disclosure, the third elastic member 2321 may be a spring. The third plug member 2322 is spherical, so that the third plug member 2322 can move smoothly within the flow passage section 603, avoiding jamming of the third plug member 2322 under the drive of the third elastic member 2321 or the mixture, ensuring the stability of the seal of the feed end 601 and facilitating being driven by the mixture. The cross-section of the flow passage section 603 perpendicular to the first direction may be circular, square, elliptical, etc. The third plug member 2322 may be spaced apart from the inner wall of the flow passage section 603 formed by the discharge pipe 2311 to facilitate the movement of the third plug member 2322 relative to the discharge pipe 2311. The diameter of the feed end 601 is between the diameter of the third plug member 2322 and the diameter of the flow passage section 603, and there is a narrowing section between the flow passage section 603 and the feed end 601 to facilitate guiding the third plug member 2322 to the feed end 601 and ensuring the stability of the seal of the feed end 601. A second clamping interface 700 is connected to the side of the feed end 601 away from the discharge end 602 to facilitate the clamping and connection of the discharge pipe 2311 and the conveying pipeline 26. It can be understood that in other embodiments, the third plug member 2322 may also be cylindrical, frustum-shaped, prismatic, pyramidal, etc., as long as it can match the feed end 601.

[0081] The housing 231 further includes a discharge head 2313. The discharge head 2313 is arranged on the discharge pipe 2311. The discharge flow passage 600 sequentially penetrates through the discharge pipe 2311 and the discharge head 2313 to form a feed end 601 in the discharge pipe 2311 and a discharge end 602 in the discharge head 2313. Thus, the arrangement of the discharge head 2313 can make the discharge end 602 closer to the discharge port 200, reducing the amount of the mixture remaining between the discharge end 602 and the discharge port 200, so that the remaining mixture cannot drip under the action of the surface tension between the discharge head 2313 and the decorative shell 40.
