[0055] In order to better understand the above technical solutions, the technical solutions of the embodiments of the present application will be described in detail below with the help of the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present application, and are not limitations of the technical solutions of the present application. In the case of no conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0056] As Figure 1 shown, according to the first aspect of the present application, a liquid supply device 100 is provided, comprising: a bracket 110; a flow distribution assembly 120 connected to the bracket 110, and a gap is formed between the flow distribution assembly 120 and the bracket 110; a liquid supply pipeline 130, one end of the liquid supply pipeline 130 passes through the bracket 110 and is located in the gap.

[0057] It can be understood that in the case of making a beverage, the shunt assembly 120 abuts the powdered food material, the liquid is delivered through the liquid supply channel 130, and after being shunted through the shunt assembly 120, it drops onto the powdered food material to brew the beverage. Since part of the liquid supply channel 130 is located in the gap, the liquid can quickly and uniformly disperse in the gap space, and then the liquid uniformly drops from the water distribution assembly, improving the uniformity of the water supply, and without opening a hole at the end face of the support 110, the liquid is prevented from leaking to the side of the support 110 away from the shunt assembly 120, and at the same time, the powdered food material cannot be sucked back through the shunt assembly 120 to block the through hole of the support 110, ensuring smooth water flow, and the user does not need to disassemble the support 110 for cleaning, improving the user experience.

[0058] In the process of making a beverage, the liquid flows out of the liquid supply channel 130 and can quickly and uniformly disperse in the gap space, and then uniformly drop from the shunt assembly 120, avoiding the situation of local dripping, ensuring that the powdered beverage can be uniformly and fully mixed with the liquid, ensuring the quality of the brewed beverage, and avoiding the situation that the local powdered beverage is not infiltrated by the liquid, affecting the quality of the beverage.

[0059] In some examples, as shown in Figure 1 The liquid supply device 100 further comprises a liquid inlet 140, which is provided on the side of the liquid supply channel 130 and located in the gap.

[0060] It can be understood that the liquid supply device 100 is provided with a liquid inlet 140 at one end of the gap, and the liquid inlet 140 is located on the side of the liquid supply channel 130. In this way, the liquid is sprayed from the side of the liquid supply channel 130 into the gap through the liquid inlet 140, so that the liquid can quickly and uniformly disperse in the gap, and then uniformly drop from the water distribution assembly to the powdered food material. Avoiding the liquid dropping vertically to the water distribution assembly, the liquid can only drop from the local water distribution assembly to the powdered food material, resulting in the situation that part of the powdered food material is not soaked in the liquid, and the brewing is not sufficient, affecting the user experience.

[0061] It can be understood that the liquid inlet 140 can be provided with a plurality of liquid inlets 140, and the plurality of liquid inlets 140 are located at the same height position of the liquid supply channel 130, and the included angle between adjacent liquid inlets 140 is the same. In this way, by spraying water through multiple liquid inlets 140 at the same time, the liquid can be more quickly and uniformly dispersed in the gap, so that the liquid can uniformly and simultaneously drop onto the powdered food material, ensuring uniform brewing and improving the efficiency of beverage making.

[0062] For example, the number of liquid inlets 140 can be five, and the included angle between adjacent liquid inlets 140 is the same, which ensures that the spraying range of the liquid inlets 140 covers the space between the support 110 and the carrier assembly 220, and further improves the uniformity of the water supply.

[0063] In some examples, the liquid supply device 100 further comprises a nozzle connected to the liquid supply pipe 130,

[0064] The liquid outlet 140 is arranged on the side of the nozzle.

[0065] It can be understood that one end of the liquid supply pipe 130 is provided with an opening, the nozzle is connected to the liquid supply pipe 130, liquid can be transported from the liquid supply pipe 130 to the nozzle, and the nozzle is located in the gap and is provided with a liquid outlet 140 on the side of the nozzle to spray water into the gap through the liquid outlet 140. In this way, the nozzle is simple and quick to install and disassemble, which facilitates cleaning and maintenance of the nozzle after a period of use, ensures smooth water flow, and improves user experience.

[0066] In some examples, as shown in Figure 1 The bracket 110 is provided with a recess 111, and the recess 111 is recessed away from the shunt assembly 120. Part of the liquid supply pipe 130 is located in the recess 111.

[0067] It can be understood that the bracket 110 is provided with a recess 111 at the end face, and the part of the liquid supply pipe 130 located in the gap is arranged in the recess 111, so that the liquid supply pipe 130 does not exceed the end face of the bracket 110 close to the shunt assembly 120, avoiding the liquid supply pipe 130 from being pressed against the shunt assembly 120, causing the water flow to be not smooth. In addition, since the liquid outlet 140 is arranged on the side of the liquid supply pipe 130, part of the liquid sprayed by the liquid outlet 140 will touch the side wall of the recess 111, so as to change the flow direction of the liquid and slow down the flow rate of the liquid, so that the liquid uniformly covers the gap and uniformly drips from the water distribution assembly to the powdered food material.

[0068] In some examples, as shown in Figure 1 The bracket 110 and the liquid supply pipe 130 are of an integrated structure; and / or a sealing member 160 is arranged between the liquid supply pipe 130 and the bracket 110.

[0069] It can be understood that the bracket 110 and the liquid supply pipe 130 can be of an integrated design. In this way, the leakage of liquid from the gap between the liquid supply pipe 130 and the bracket 110 is avoided, so as to ensure the water flow effect and the structural strength of the bracket 110 and the liquid supply pipe 130. Alternatively, the bracket 110 and the liquid supply pipe 130 are of a split structure, and the connection between the liquid supply pipe 130 and the bracket 110 is provided with a sealing member 160 to prevent liquid from leaking from the connection. In this way, the liquid supply pipe 130 is convenient to replace, the processing difficulty is reduced, and the cost is saved. The bracket 110 and the liquid supply pipe 130 can be of an integrated structure or a split structure according to actual production conditions.

[0070] In some examples, as shown in Figure 1As shown, the liquid supply device 100 further comprises a guide assembly 150 arranged on the support 110 and located in the gap, for guiding the liquid outputted via the liquid supply pipeline 130.

[0071] It can be understood that the guide assembly 150 is arranged on the end of the support 110 close to the carrier assembly 220, and in the process of making the beverage, when the liquid supply pipeline 130 sprays the liquid between the support 110 and the carrier assembly 220, the guide assembly 150 guides the liquid in the gap formed by the support 110 and the carrier assembly 220, so that the liquid flows more regularly, and the water supply is more uniform, avoiding local water supply, which causes part of the powdered food materials not to be soaked in the liquid.

[0072] In some examples, as shown in Figure 1 As shown, the guide assembly 150 comprises a guide piece 151 arranged on the support 110 and extending away from the liquid supply pipeline 130 in the direction where the liquid supply pipeline 130 is located; and / or a convex point 152 arranged on the support 110.

[0073] It can be understood that the guide assembly 150 is provided with the guide piece 151, which is arranged on the end surface of the support 110 close to the carrier assembly 220, and the guide piece 151 is regularly arranged, specifically, the guide piece 151 extends away from the liquid supply pipeline 130 in the direction where the liquid supply pipeline 130 is located, so that when the liquid is sprayed from the liquid supply pipeline 130, part of the liquid flows into the guide piece 151 and flows along the guide piece 151 away from the liquid supply pipeline 130, so that the liquid can drip from the position close to the liquid supply pipeline 130 to the position close to the edge of the support 110, thereby making the liquid spread in the space between the support 110 and the carrier assembly 220, and the water supply is more uniform, avoiding concentrated water supply, which causes part of the powdered food materials not to be in contact with the liquid, thereby improving the brewing efficiency and quality.

[0074] The convex point 152 is arranged on the end surface of the support 110 close to the carrier assembly 220, and part of the liquid that does not pass through the guide piece 151 will flow through the convex point 152, change the flow direction through the convex point 152, and slow down the flow speed of the liquid, so as to reduce the impact force, making the brewing process more gentle and improving the brewing effect.

[0075] For example, the end surface of the support 110 close to the carrier assembly 220 can be circular, the guide piece 151 can be arranged in the radial direction of the support 110, the liquid supply pipeline 130 is arranged at the center position of the support 110, one end of the guide piece 151 abuts against the liquid supply pipeline 130, and the other end is located at the edge of the support 110.

[0076] In some examples, as shown in Figure 1As shown, the guide pieces 151 are multiple; the convex points 152 are multiple, and are arranged between every two adjacent guide pieces 151.

[0077] It can be understood that the guide pieces 151 are multiple, and are regularly arranged on the end surface of the support 110 close to the carrier assembly 220; specifically, each guide piece 151 extends from the direction of the liquid supply pipeline 130 to the direction away from the liquid supply pipeline 130, and the convex points 152 are multiple, and are arranged between every two adjacent guide pieces 151; in this way, through the joint action of the multiple guide pieces 151 and the multiple convex points 152, it is further ensured that the liquid can spread in the space between the support 110 and the carrier assembly 220, and the adjustment of the flow speed of the liquid is more obvious, thereby ensuring the quality and effect of brewing.

[0078] The included angle between the adjacent guide pieces 151 is the same; the area of the support 110 close to the liquid supply pipeline 130 is a first area, and the area away from the liquid supply pipeline 130 is a second area, and the distribution density of the convex points 152 in the first area is greater than that in the second area.

[0079] It can be understood that since the liquid flow speed near the liquid supply pipeline 130 is the fastest, the deceleration and rectification effect of the liquid by the dense convex points 152 in the first area is significant, the liquid after preliminary deceleration and rectification flows to the second area, and then is decelerated and rectified by the convex points 152 in the second area, so as to make the water supply more uniform and the liquid flow speed more suitable for brewing, thereby improving the brewing efficiency, ensuring the brewing effect, and improving the user experience.

[0080] The distribution density of the convex points 152 close to the liquid supply pipeline 130 in the first area is greater, so as to ensure the effect of slowing down the liquid flow speed and rectification.

[0081] The included angle between every two adjacent guide pieces 151 is equal, so as to ensure the rectification effect of the entire guide piece 150 on the liquid, avoid turbulent flow due to uneven guide direction of the guide piece 151 or inconsistent local liquid flow speed, and improve the flow guiding effect and stability.

[0082] For example, the end surface of the support 110 close to the carrier assembly 220 can be circular, and 12 guide members 151 can be arranged at equal angles thereon, and four convex points 152 can be arranged on the center line of each adjacent two guide members 151, and the distance between adjacent two convex points 152 is equal. The convex points 152 close to the liquid supply pipeline 130 are distributed more densely. Since the liquid flow rate near the liquid supply pipeline 130 is the fastest, the liquid is significantly slowed down and straightened by the dense convex points 152, and then the liquid is slowed down and straightened by the subsequent convex points 152, so that the water supply is more uniform and the liquid flow rate is more suitable for brewing, thereby improving the brewing efficiency, ensuring the brewing effect, and improving the user experience.

[0083] In some examples, the guide member 151 is a guide groove or a convex rib.

[0084] It can be understood that, in the case that the guide member 151 is a guide groove, the liquid flows in the guide groove and flows along the guide groove away from the liquid supply pipeline 130 to be straightened. In the case that the guide member 151 is a convex rib, the convex rib changes the flow direction of the liquid when the liquid flows through the convex rib, so that the liquid flows regularly away from the liquid supply pipeline 130 to be straightened.

[0085] In some examples, as shown in Figure 1 The shunt assembly 120 includes a filter screen 121, and the periphery of the filter screen 121 is connected to the support 110.

[0086] It can be understood that the shunt assembly 120 is provided with the filter screen 121, the filter screen 121 is fixed on the support 110 through the periphery, and a plurality of shunt holes 123 are formed in the filter screen 121 and uniformly distributed on the filter screen 121, so that the liquid can uniformly flow out of the shunt holes 123, thereby ensuring the brewing efficiency and the brewing effect. In addition, the connection between the filter screen 121 and the support 110 is arranged at the periphery of the filter screen 121, avoiding the end surface of the filter screen 121, so that the shunt holes 123 can be formed at any position of the end surface of the filter screen 121 without being blocked, and the liquid can be uniformly dripped on the powdery food material.

[0087] It can be understood that the filter screen 121 can be made of a flexible material. When the liquid is delivered to the gap between the filter screen 121 and the support 110, the impact of the liquid will cause the position of the filter screen 121 close to the liquid supply pipeline 130 to sink, thereby increasing the gap space, improving the temporary storage effect of the gap on the water, and ensuring that the liquid is fully guided and changes the flow rate in the gap, thereby ensuring the brewing efficiency and the brewing effect.

[0088] It can be understood that one end surface of the filter screen 121 is a smooth surface, and the other end surface is provided with a groove. The smooth surface faces the carrier assembly 220, so that the powdery food material is not adsorbed in the groove, and the subsequent cleaning work is facilitated.

[0089] Exemplarily, the circumferential side of the filter screen 121 and the side surface of the support 110 are provided with threaded holes, and the filter screen 121 is fixed to the support 110 by sequentially threading bolts through the threaded holes of the filter screen 121 and the support 110.

[0090] Exemplarily, the hoop is sleeved on the circumferential side of the filter screen 121 to fix the filter screen 121 to the support 110.

[0091] In some examples, as shown in Figure 1 The shunt assembly 120 further includes a fastener 122 connected to the support 110 through the circumferential side of the filter screen 121.

[0092] It can be understood that the circumferential side of the filter screen 121, i.e., the end face edge of the filter screen 121, is provided with a connecting hole, and the filter screen 121 is fixed to the support 110 by threading the fastener 122 through the connecting hole, so as to avoid the center position of the end face of the filter screen 121 and reduce the area of the filter screen 121 that is blocked, thereby ensuring that the liquid can be uniformly dripped to the powdered food material.

[0093] In some examples, as shown in Figure 1 The fastener 122 is a plurality of fasteners 122, and the plurality of fasteners 122 are distributed at equal intervals on the circumferential side of the filter screen 121.

[0094] It can be understood that the number of fasteners 122 is a plurality, and correspondingly, the number of connecting holes is also a plurality, and they are all located at the end face edge of the filter screen 121, so as to avoid the end face position of the filter screen 121, reduce the area of the filter screen 121 that is blocked, and ensure that the liquid can be uniformly dripped to the powdered food material while ensuring the connection and fastening of the filter screen 121 and the support 110.

[0095] It can be understood that the existing fastener 122 is usually arranged at the center position of the filter screen 121, which causes deformation at the center of the filter screen 121, low service life of the filter screen 121, and inability to discharge water at the center, thereby causing uneven brewing of the beverage. Therefore, the distance between each connecting hole and the center of the filter screen 121 is equal, the included angle between adjacent connecting holes is the same, the fastener 122 is threaded through the connecting hole to fix the filter screen 121 to the support 110, and such arrangement makes the force distribution of the filter screen 121 uniform and avoids local deformation.

[0096] Exemplarily, the number of fasteners 122 is three, and the number of connecting holes is also three, and the included angle between adjacent connecting holes is 120°.

[0097] In some examples, as shown in Figure 2 and Figure 3 The liquid supply device 100 further includes a seal 160 connected to the support 110, and the filter screen 121 is inserted into the seal 160.

[0098] It can be understood that the support 110 is provided with a plug block at one end close to the filter screen 121, and the sealing element 160 is provided with a plug slot at two ends. The plug block is inserted into the plug slot at one end of the sealing element 160, and the filter screen 121 is inserted into the plug slot at the other end of the sealing element 160, so that the filter screen 121 is connected to the support 110. In this way, the fastener 122 can be connected to the support 110 through the circumferential side of the filter screen 121, further improving the fixing effect. On the other hand, it avoids the liquid in the gap formed by the support 110 and the filter screen 121 from flowing into the beverage machine 200, affecting the normal work of the beverage machine 200, improving the sealing effect, and reducing the safety hidden trouble.

[0099] In some examples, a plurality of shunt holes 123 are formed on the filter screen 121, and the diameter of the shunt hole 123 is 0.15mm to 0.8mm; the distance between adjacent two shunt holes 123 is 1mm to 3mm.

[0100] It can be understood that the diameter of the shunt hole 123 is set to 0.15mm to 0.8mm. It ensures the water outlet efficiency while preventing the powder food from being sucked back. When the diameter of the shunt hole 123 is less than 0.15mm, the water outlet effect of the shunt hole 123 is poor, affecting the water outlet efficiency; when the diameter of the shunt hole 123 is greater than 0.8mm, the diameter is too large, which easily causes the powder food to be sucked back, thereby affecting the normal water outlet and being difficult to clean.

[0101] It can be understood that the distance between adjacent two shunt holes 123 is set to 1mm to 3mm. It ensures the water outlet speed and guarantees the brewing effect. When the distance between adjacent two shunt holes 123 is less than 1mm, the shunt holes 123 are too dense, which causes the water to flow too fast and easily leads to insufficient brewing; when the distance between adjacent two shunt holes 123 is greater than 3mm, the shunt holes 123 are too few, which causes the water to flow too slowly and reduces the brewing efficiency, affecting the user experience.

[0102] In some examples, the liquid supply device 100 further comprises: a one-way valve arranged in the liquid supply pipeline 130.

[0103] It can be understood that the one-way valve is arranged in the liquid supply pipeline 130 close to the shunt assembly 120. During the preparation of the beverage, the liquid in the liquid supply pipeline 130 will only flow to the shunt assembly 120 under the limitation of the one-way valve, avoiding the backflow of the liquid in the gap, ensuring that the liquid in the liquid supply pipeline 130 will not be contaminated by the powder food, ensuring the cleanliness of the liquid, and the one-way valve can stabilize the pressure during the preparation of the beverage, improve the quality of the beverage, and improve the user experience.

[0104] For example, the one-way valve can be a back pressure one-way valve. Under the pressure of the liquid in the liquid supply pipeline 130, the valve is opened, so that the liquid flows to the gap in one direction, ensuring the one-way flow of the liquid.

[0105] As shown in Figure 2 and Figure 3 , according to the second aspect of the embodiments of the present application, a beverage machine 200 is provided, comprising the liquid supply device 100 as described in any of the above technical solutions, thus having all the beneficial effects of the liquid supply device 100, which will not be repeated here.

[0106] As shown in Figures 2 to 4 , the beverage machine 200 further comprises a housing 210, and the liquid supply device 100 is connected to the housing 210; a carrier assembly 220, which is detachably connected to the housing 210, and in the case where the carrier assembly 220 is connected to the housing 210, the carrier assembly 220 is at the bottom of the liquid supply device 100.

[0107] It can be understood that the carrier assembly 220 is used to carry the powdered food material, and in the case of making a beverage, the ground powdered food material is placed in the carrier assembly 220, the carrier assembly 220 is connected to the housing 210 and is located at the bottom of the liquid supply device 100, and the liquid is delivered by the liquid supply device 100 to brew the powdered food material to complete the making of the beverage. After the beverage is made, the carrier assembly 220 can be detached for cleaning or refilling the powdered food material.

[0108] In some examples, as shown in Figure 2 and Figure 3 , the above-mentioned bracket 110 is slidingly connected to the above-mentioned housing 210, and the above-mentioned beverage machine 200 further comprises a driving assembly, which is connected to the above-mentioned bracket 110 and is used to drive the above-mentioned bracket 110 to approach or move away from the above-mentioned carrier assembly 220.

[0109] It can be understood that in the case of making a beverage, after connecting the carrier assembly 220 carrying the powdered food material to the shell 210, the sliding bracket 110 is slid so that the liquid supply device 100 moves towards the carrier assembly 220 until the liquid supply device 100 moves to a specified position so that the shunt assembly 120 is close to the powdered food material, and the liquid supply device 100 provides liquid to the carrier assembly 220 through the liquid supply pipeline 130 to brew the powdered food material to obtain a beverage. After the beverage is made, the sliding bracket 110 is slid again so that the liquid supply device 100 moves away from the carrier assembly 220 to facilitate the separation of the carrier assembly 220 and the shell 210. The end of the existing beverage machine 200 shell 210 for connecting the carrier assembly 220 is provided with an internal thread, and the carrier assembly 220 is provided with an external thread, so as to screw the carrier assembly 220 into the shell 210, and at the same time, the carrier assembly 220 is lifted in the axial direction to approach the water shunt assembly. When the carrier assembly 220 is lifted into position, the beverage making process can continue. However, during this process, the handle of the carrier assembly 220 is likely to interfere with the beverage machine 200, causing bumps. Moreover, the user cannot know the degree of connection and tightening of the carrier assembly 220 and the shell 210, and usually needs to exert a lot of force to ensure that the screwing is in place. When the screwing is not in place, the connection between the carrier assembly 220 and the shell 210 is loose, and there is a risk of the carrier assembly 220 falling off the shell 210 during the beverage making process, affecting the user experience. In the case of making hot beverages, the user needs to manually remove the carrier assembly 220 after making. There is a risk of burns during the screwing process. In the present application, during the entire process of making a beverage, the liquid supply assembly is slid to approach or move away from the carrier assembly 220, so that the user does not need to manually screw the carrier assembly 220, reducing the complexity of user operation, reducing the difficulty of user use, avoiding the situation that the carrier assembly 220 falls off the shell 210 due to improper screwing, reducing the risk of burns, and improving the user experience.

[0110] For example, the powdered food material carried by the carrier assembly 220 can be ground coffee powder. After the carrier assembly 220 is installed in place, the liquid supply assembly is lowered to a specified position and liquid is dropped onto the surface of the coffee powder to brew coffee. The liquid can be hot water or hot milk according to user preference, improving the user experience.

[0111] It can be understood that when the beverage is made, the driving assembly is started to drive the liquid supply device 100 to slide towards the carrier assembly 220 until the liquid supply device 100 moves to the specified position, and then the driving assembly is started again to drive the liquid supply device 100 to slide away from the carrier assembly 220 so that the user can take out the carrier assembly 220 from the shell 210. During the whole process, the driving power is provided by the driving assembly to improve the automation degree of the product, and the user does not need to manually move the carrier assembly 220, which reduces the operation complexity of the user, reduces the use difficulty of the user, and improves the user experience.

[0112] In some examples, as shown in Figure 2 and Figure 3 The driving assembly includes a medium supply part 230, the bracket 110 is slidingly connected to the medium supply part 230 and the shell 210, and a medium cavity 231 is formed between the bracket 110 and the medium supply part 230. When the medium supply part 230 injects medium into the medium cavity 231, the bracket 110 moves towards the carrier assembly 220.

[0113] It can be understood that in the case of making a beverage, the medium supply part 230 is started to deliver medium into the medium cavity 231 to increase the pressure in the medium cavity 231. Since the bracket 110 is slidingly connected to the medium supply part 230, when the pressure in the medium cavity 231 increases to a certain degree, the pressure pushes the bracket 110 away from the medium supply part 230 to expand the volume of the medium cavity 231, so that the bracket 110 moves towards the carrier assembly 220 until the bracket 110 moves to the specified position and stops delivering medium. The driving power is provided by delivering the medium to improve the automation degree of the product, and the user does not need to manually move the carrier assembly 220, which reduces the operation complexity of the user, reduces the use difficulty of the user, and improves the user experience.

[0114] It can be understood that the injected medium includes liquid and gas, and when the beverage is made, the medium is discharged from the medium cavity 231 so that the bracket 110 moves away from the carrier assembly 220. The selected medium is harmless to the human body and does not affect the flavor of the beverage.
