Description

Technical Field

[0001] This application relates to the field of liquid preparation structure technology, and in particular to liquid preparation devices and beverage preparation equipment. Background Technology

[0002] With the improvement of living standards, beverage making equipment such as coffee machines and self-service cola machines are gradually appearing in various application scenarios. Currently, the cleaning and descaling of beverage making equipment such as coffee machines are generally carried out using tablet-shaped cleaning agents. Taking the cleaning of the coffee machine brewing system as an example, when cleaning the brewer and coffee machine tubing inside the coffee machine, the tablets are manually inserted into the brewer through the tablet channel next to the bean hopper at the top of the coffee machine. The tablets gradually dissolve in the brewer to clean the inside of the coffee system of the coffee machine.

[0003] However, this type of beverage-making equipment has the following drawbacks in actual use: First, during the cleaning process, the tablets gradually dissolve in the beverage-making circuit. Because the circuit is constantly flowing, the tablets do not dissolve completely, which can affect the cleaning performance of the equipment.

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] See Figure 1 An embodiment of this application provides a beverage preparation device, including a liquid dispensing device 100 and a beverage preparation component, wherein the beverage preparation component is provided with a beverage preparation circuit.

[0036] Specifically, such as Figures 2 to 3 As shown, the liquid preparation device 100 includes a liquid preparation container 110, a switching assembly 120, and a carrying assembly 130. The carrying assembly 130 is provided with a first liquid inlet 130a and a first liquid outlet 130b. The first liquid outlet 130b can communicate with the beverage preparation assembly, so that the first liquid outlet 130b can discharge washing solution into the beverage preparation circuit to clean the beverage preparation circuit.

[0037] The switching assembly 120 is rotatably mounted on the support assembly 130. The switching assembly 120 is provided with a second liquid inlet 120a, a second liquid outlet 120b, and a flow channel 120c at intervals. The flow channel 120c is not connected to either the second liquid inlet 120a or the second liquid outlet 120b. A dispensing container 110 is connected to the switching assembly 120. The dispensing container 110 is provided with a dispensing chamber 110a. The second liquid inlet 120a and the second liquid outlet 120b can communicate with the dispensing chamber 110a. When the dispensing container 110 drives the switching assembly 120 to rotate synchronously relative to the support assembly 130, the switching assembly 120 switches between at least a first position and a second position, switching communication between the first liquid inlet 130a and the second liquid inlet 120a or the liquid inlet end of the flow channel 120c, and switching communication between the first liquid outlet 130b and the second liquid outlet 120b or the liquid outlet end of the flow channel 120c.

[0038] That is, when the switching component 120 is in the first position, the first liquid inlet 130a is connected to the second liquid inlet 120a, and the second liquid outlet 120b is connected to the first liquid outlet 130b. In other words, when the switching component 120 is in the first position, the first liquid inlet 130a, the second liquid inlet 120a, the liquid dispensing chamber 110a, the second liquid outlet 120b, and the first liquid outlet 130b are sequentially connected to form the first branch.

[0039] When the switching component 120 is in the second position, the first liquid inlet 130a, the flow channel 120c, and the first liquid outlet 130b are sequentially connected to form a second branch. Furthermore, the first liquid inlet 130a is not connected to the second liquid inlet 120a, and the first liquid outlet 130b is not connected to the second liquid outlet 120b.

[0040] Thus, by rotating the switching component 120, the first branch formed by the sequential connection of the first liquid inlet 130a, the second liquid inlet 120a, the liquid dispensing chamber 110a, the second liquid outlet 120b, and the first liquid outlet 130b, and the second branch formed by the sequential connection of the first liquid inlet 130a, the flow channel 120c, and the first liquid outlet 130b can be switched. This allows for switching between a cleaning mode using a detergent-containing washing solution and a direct water washing mode, enriching the cleaning scenarios.

[0041] Furthermore, unlike the preparation of the washing solution by dissolving the medicine in the beverage preparation circuit, the dissolution of the detergent can be completed in the dissolution chamber by setting the dissolution container 110, so that the undissolved detergent can be retained in the dissolution chamber as much as possible, thereby avoiding the difficulty of cleaning caused by detergent residue.

[0042] In addition, by rotating the switching component 120 to switch between the first and second positions via the liquid preparation container 110, the user can switch cleaning scenarios simply by rotating the liquid preparation container 110, which improves the convenience of operation.

[0043] It should be noted that switching between A and B or C refers to the existence of a switching scenario, i.e., A and B are connected, or A and C are connected. Each time A is connected, it involves only one entity. Specifically, in one example, switching between the first liquid inlet 130a and the liquid inlet of the second liquid inlet 120a or the liquid inlet end of the flow channel 120c means that the first liquid inlet 130a can switch to be connected to the second liquid inlet 120a, or it can switch to be connected to the liquid inlet end of the flow channel 120c.

[0044] In some embodiments, the dispensing container 110 and the switching component 120 are detachably connected. This facilitates the disassembly of the dispensing container 110 to replace the detergent with a new one, ensuring effective cleaning. The detachable connection between the dispensing container 110 and the switching component 120 can be, but is not limited to, snap-fit, abutment, magnetic attraction, etc., and is not further restricted here.

[0045] Furthermore, see you again Figure 2 In one embodiment, one of the liquid preparation container 110 and the switching component 120 is provided with a connector 121, and the other is provided with a mating connector 112. The connector 121 and the mating connector 112 are connected and engaged, so that the liquid preparation container 110 and the switching component 120 are snapped together. In this way, the provision of the connector 121 and the mating connector 112 not only realizes the detachable connection between the liquid preparation container 110 and the switching component 120, but also ensures the stability of the connection, which is beneficial to the stable switching of the first branch and the second branch.

[0046] Furthermore, in other embodiments, such as Figure 2 As shown, the liquid preparation container 110 also has a third liquid outlet 110c and a third liquid inlet 110b. The third liquid outlet 110c and the third liquid inlet 110b communicate with the liquid preparation chamber 110a. The liquid preparation container 110 has a plug-in fitting 112, which has two plug-in fitting portions 112a. The third liquid outlet 110c and the third liquid inlet 110b are respectively disposed on the two plug-in fitting portions 112a. The switching assembly 120 includes a plug-in member 121. The plug-in member 121 includes two plug-in portions 121a. The plug-in portions 121a and the plug-in fitting portions 112a are plugged into each other. The two plug-in portions 121a are respectively disposed on the second liquid inlet 120a and the second liquid outlet 120b. When the connector 121 and the connector 112 are connected, the third liquid outlet 110c is connected to the second liquid outlet 120b, and the third liquid inlet 110b is connected to the second liquid inlet 120a.

[0047] Thus, through the snap-fit ​​engagement of the plug-in 121 and the plug-in mating part 112, the liquid preparation container 110 and the switching component 120 are snap-fitted together, and the third liquid outlet 110c is connected to the second liquid outlet 120b, and the third liquid inlet 110b is connected to the second liquid inlet 120a. That is, the second liquid outlet 120b and the second liquid inlet 120a can be connected to the liquid preparation chamber 110a without the need for additional snap-fit ​​structures or pipes, which helps to save the installation space of the liquid preparation device 100.

[0048] In conjunction with any embodiment of the switching component 120 described above, in conjunction with Figure 2 , Figure 4 as well as Figure 5 As shown, the switching assembly 120 also includes a mounting bracket 122 and a first seal 123. At least one of the first seal 123 and the plug-in member 121 is movably connected to the mounting bracket 122. A second liquid inlet 120a and a second liquid outlet 120b are connected and disposed between the mounting bracket 122 and the plug-in member 121a. The mounting bracket 122 is provided with a flow channel 120c. Two through holes are respectively provided with the second liquid outlet 120b and the second liquid inlet 120a. At least one of the second liquid inlet 120a and the second liquid outlet 120b is provided with a large hole 1212 and a small hole 1211, which are connected and disposed in communication. The first seal 123 is retractably inserted into at least one of the second liquid inlet 120a and the second liquid outlet 120b.

[0049] Understandably, in one installation scenario, the first seal 123 is connected to the mounting bracket 122, and the connector 121 extends and retracts outside the first seal 123, allowing the connector 121 to move relative to the mounting bracket 122. When the liquid preparation container 110 is inserted into the switching assembly 120, the liquid preparation container 110 and the connector 121 abut against each other, causing the first seal 123 to be pushed up relative to the connector 121 in a direction close to the liquid preparation container 110, thereby separating the first seal 123 from the small hole 1211. The small hole 1211 is located near the bearing assembly 130, and the large hole 1212 is located near the liquid preparation container 110.

[0050] In another installation scenario, the connector 121 is connected to the mounting bracket 122, and the first seal 123 is retractably and movably mounted on the mounting bracket 122. When the liquid preparation container 110 is inserted into the switching assembly 120, the liquid preparation container 110 abuts against the first seal 123, causing the first seal 123 to move relative to the connector 121 in a direction closer to the support assembly 130, so that the first seal 123 seals against the small hole 1211. The small hole 1211 is located near the liquid preparation container 110, and the large hole 1212 is located near the support assembly 130.

[0051] That is, such as Figure 6 as well as Figure 7 As shown, when the liquid preparation container 110 and the switching assembly 120 are engaged (i.e., the connector 121 and the engagement component 112), Plug (For details, please refer to the following section.) Figure 6 On the left side, the liquid preparation container 110 abuts against the first seal 123 or the plug-in 121. The liquid preparation container 110 can abut against the first seal 123 relative to the switching assembly 120 to the third position, so that the first seal 123 moves from the small hole 1211 to the large hole 1212 relative to the second liquid inlet 120a and the second liquid outlet 120b. The first seal 123 can be spaced apart from the inner sidewalls of the large hole 1212 and the small hole 1211 to form a flow gap 123a.

[0052] Please see details. Figure 6 The right side, and see the reference. Figure 8 As shown, when the liquid preparation container 110 and the switching component 120 are spaced apart, the liquid preparation container 110 and the switching component 120 are not installed in place. The liquid preparation container 110, the switching component 120 and the first sealing member 123 are all spaced apart. The first sealing member 123 can be in the fourth position relative to the switching component 120, so that the outer wall of the first sealing member 123 can abut against the inner wall of the small hole 1211 and seal.

[0053] In this way, the first sealing element 123 can cooperate with the switching component 120 to ensure that when the liquid preparation container 110 and the switching component 120 are not properly aligned, at least one of the second liquid inlet 120a and the second liquid outlet 120b will not be connected, thus disconnecting the first branch. This achieves a sealing performance between the liquid preparation container 110 and the switching component 120, thereby preventing water leakage from the liquid preparation device 100 and improving the safety of the liquid preparation device 100.

[0054] Additionally, optionally, in one embodiment, see back Figure 5 , Figure 7 as well as Figure 8 The switching assembly 120 also includes an elastic element 124. The elastic element 124 is connected to the plug-in member 121. The first sealing member 123 is telescopically inserted and engaged with the plug-in member 121 through the elastic element 124, so that the first sealing member 123 elastically expands and contracts relative to at least one of the second liquid inlet 120a and the second liquid outlet 120b.

[0055] Understandably, when one of the first sealing element 123 and the plug-in element 121 is pressed against the support component 130 by the liquid dispensing container 110, the other moves relative to the direction of the large hole 1212, causing the elastic element 124 to be in a compressed state. When the liquid dispensing container 110 releases the pressure on the plug-in element 121 and the first sealing element 123, the elastic element 124 can reset, causing the first sealing element 123 to move towards the small hole 1211, so that the first sealing element 123 returns to the state of contact with the small hole 1211. Thus, the setting of the elastic element 124 facilitates automatic mechanical reset, enabling rapid response and efficient leak-proof function. In addition, the structure of the elastic element 124 is relatively simple, easy to design, and helps to reduce processing costs.

[0056] In one installation scenario, the elastic element 124 is disposed between the first seal 123 or the plug 121 and the support assembly 130. In another installation scenario, the elastic element 124 is sleeved on the outside of the first seal 123, and the support assembly 130 is sleeved on the outside of the elastic element 124.

[0057] In one embodiment, see back Figure 7 At least one of the second liquid inlet 120a and the second liquid outlet 120b is further provided with a tapered hole 1213, and a large hole 1212 and a small hole 1211 are arranged opposite to each other. The tapered hole 1213 connects the large hole 1212 and the small hole 1211. Thus, when the first seal 123 moves between the large hole 1212 and the small hole 1211, the shape design of the tapered hole 1213 helps to reduce the movement resistance of the first seal 123 and reduce the impact and wear caused by the rapid movement of the first seal 123.

[0058] Furthermore, the presence of the conical orifice 1213 enhances the sealing effect. When the first seal 123 abuts against the small orifice 1211, the shape of the conical orifice 1213 allows the first seal 123 to better fit the edge of the small orifice 1211, preventing liquid leakage from gaps and ensuring the sealing performance between the liquid dispensing container 110 and the switching assembly 120, thus ensuring the stability and reliability of the liquid dispensing device 100. In addition, the minimum orifice diameter of the conical orifice 1213 is greater than or equal to the orifice diameter of the small orifice 1211, and the maximum orifice diameter of the conical orifice 1213 is less than or equal to the orifice diameter of the large orifice 1212. This allows first seals 123 of different sizes to be sealed through the conical orifice 1213, increasing the variety of installation scenarios and improving the adaptability of the liquid dispensing device 100.

[0059] Accordingly, in another embodiment, the first sealing member 123 includes a first body 1231 and a second body 1232. The first body 1231 is connected to the mounting support 122. The first body 1231 has a hollow portion, which communicates with at least one of the second liquid inlet portion 120a and the second liquid outlet portion 120b. The second body 1232 is gradually tapered towards the liquid dispensing container 110. That is, the wall surface of the second body 1232 is inclined.

[0060] Similarly, when the first seal 123 moves between the large hole 1212 and the small hole 1211, the inclined design of the outer wall of the second body 1232 helps to reduce the movement resistance of the first seal 123 and reduce the impact and wear caused by the rapid movement of the first seal 123.

[0061] Furthermore, when the first sealing element 123 abuts against the orifice 1211, the inclined wall surface of the second body 1232 allows the first sealing element 123 to better fit the edge of the orifice 1211, preventing liquid leakage from gaps and ensuring the sealing performance between the liquid dispensing container 110 and the switching assembly 120, thus ensuring the stability and reliability of the liquid dispensing device 100. In addition, first sealing elements 123 of different sizes can also seal against the orifice 1211 at different positions, increasing the variety of installation scenarios and improving the adaptability of the liquid dispensing device 100.

[0062] To further improve the sealing performance between the switching assembly 120 and the supporting assembly 130, in some embodiments, the switching assembly further includes a second seal 125 and a protrusion 126. A second liquid inlet 120a and a second liquid outlet 120b are disposed on the protrusion. A connector 121 is sleeved on the outside of the protrusion 126, and the connector 121 is movably extendable and retractable within the protrusion 126. The second seal 125 is sleeved on the outside of the protrusion 126, and when the liquid dispensing container 110 abuts against the switching assembly 120, the second seal 125 is sealed between the connector 121 and the protrusion 126.

[0063] In some embodiments, combined with Figure 2 as well as Figure 4 As shown, one of the supporting component 130 and the liquid dispensing container 110 is provided with an arc-shaped groove 131, and the other is provided with a protrusion 111. The protrusion 111 is slidably disposed in the arc-shaped groove 131. In this way, the design of the arc-shaped groove 131 can provide a good limiting effect for the movement of the protrusion 111, thereby improving the movement stability of the liquid dispensing container 110 relative to the supporting component 130.

[0064] In addition, in some embodiments, the arc-shaped slide groove 131 has a first end 1311 and a second end 1312 along its length direction; the slide groove also has a groove opening 1313, which is disposed at the first end 1311. The protrusion 111 slides in engagement with the arc-shaped slide groove 131 by being inserted into the groove opening 1313. The arc-shaped slide groove 131 also has a first side 1314 and a second side 1315 along its width direction. The arc-shaped slide groove 131 also has a first abutting protrusion 1316, which protrudes from the first end 1311 and is disposed at least on one of the first side 1314 and the second side 1315. The first abutting protrusion 1316 is used to abut against the protrusion 126.

[0065] Thus, the chute has a first side 1314 and a second side 1315 along its width direction, the groove opening 1313 is located at the first end 1311 of the arc-shaped chute 131, and the first abutting protrusion 1316 is located at the edge of the groove opening 1313. This allows the protrusion 111 to abut against the protrusion 111 through the positioning of the first abutting protrusion 1316 when it enters from the first end 1311 to the second end 1312. This facilitates the determination of the positioning and cooperation between the protrusion 111 and the first end 1311, improves the positioning accuracy of the liquid dispensing container 110 and the switching assembly 120 during installation, and increases the efficiency of disassembly and assembly.

[0066] In other embodiments, such as Figure 2 as well as Figure 9 As shown, the liquid dispensing device 100 also includes a sealing gasket 127, which has two through holes that communicate with the first liquid inlet 130a and the first liquid outlet 130b, respectively. One of the supporting assembly 130 and the sealing gasket 127 has a snap-fit ​​portion 127a, and the other has a snap-fit ​​mating portion 130c. The snap-fit ​​portion 127a and the snap-fit ​​mating portion 130c engage to lock the sealing gasket 127 and the supporting assembly 130 together.

[0067] Thus, the sealing gasket 127 further enhances the sealing performance between the switching assembly 120 and the carrier assembly 130. The connection between the two through holes and the first liquid inlet 130a and the first liquid outlet 130b ensures smooth liquid flow. Furthermore, the ingenious design of the snap-fit ​​part 127a and the snap-fit ​​mating part 130c allows the sealing gasket 127 to be securely installed on the carrier assembly 130, preventing it from easily falling off and improving the stability of the overall leak-proof performance of the liquid dispensing device 100.

[0068] Optionally, in one embodiment, combined with Figure 5 as well as Figure 9As shown, the liquid preparation container 110 can drive the switching component 120 to rotate relative to the support component 130, so that the first liquid inlet 130a can switch between communication with the second liquid inlet 120a or the liquid inlet end of the flow channel 120c, and the first liquid outlet 130b can switch between communication with the second liquid outlet 120b and the liquid outlet end of the flow channel 120c. The support component 130 is provided with a second abutting protrusion 1317 at a time interval, and the outer edge of the mounting support 122 is provided with an abutting engagement portion 1233. When the first liquid inlet 130a is connected to the second liquid inlet 120a, and the first liquid outlet 130b is connected to the second liquid outlet 120b, the second abutting protrusion 1317 abuts against the abutting engagement portion 1233 to limit further rotation of the switching component 120 relative to the support component 130 caused by the liquid preparation container 110. The number of second abutting protrusions 1317 can be one or two, and they are spaced apart.

[0069] In another embodiment, such as Figure 9 As shown, the surface of the mounting bracket 122 is provided with a through groove. A sealing gasket 127 abuts against the through groove to form a flow channel 120c. The sealing gasket 127 is provided with a sealing protrusion 127b, which abuts against the edge of the groove opening. Thus, the sealing performance of the flow channel 120c can be improved by the sealing protrusion 127b.
