Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and in particular to a liquid dispensing device, a brewing device, and a brewing method. Background Technology

[0002] As people's living standards improve, various brewing devices have appeared on the market that can automatically brew coffee or tea.

[0003] When a brewing device has multiple outlets, the user needs to select the outlet to dispense the liquid. Traditional brewing devices are complicated to operate and prone to human error. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this disclosure provides a liquid dispensing device, a brewing device, and a brewing method.

[0005] The first aspect of this disclosure provides a liquid dispensing device, comprising:

[0006] A liquid container is used to receive liquid. The bottom of the liquid container is provided with a first liquid outlet and a second liquid outlet. The first liquid outlet is provided with a siphon device, and the second liquid outlet is provided with an opening and closing structure.

[0007] When the liquid in the liquid-holding cup is discharged through the siphon device, the opening and closing structure closes.

[0008] In the above process, adding liquid to the container and closing the opening and closing mechanism allows the liquid in the container to be discharged from the first outlet via a siphon device. When liquid needs to be discharged from the second outlet, simply opening the opening and closing mechanism allows the liquid to be discharged from the second outlet under the action of gravity.

[0009] By controlling the amount of liquid added to the container, the liquid volume is made greater than the threshold, that is, the height of the liquid is higher than the highest point of the siphon channel. The liquid in the container enters along the inlet of the siphon channel, flows along the siphon channel, passes the highest point of the siphon channel, and is discharged from the first outlet.

[0010] By controlling the amount of liquid added to the container, the liquid volume is kept below a threshold, meaning the liquid level is below the highest point of the siphon channel. The liquid in the container cannot be discharged from the siphon channel. At this time, the liquid stays in the container for a preset time. Controlling the opening and closing structure to open allows the liquid to be discharged from the second outlet.

[0011] When adding liquid twice in sequence, the volume of the first portion of liquid added to the container can be controlled to be greater than a threshold, so that the first portion of liquid in the container enters along the inlet of the siphon channel, flows along the siphon channel, passes through the highest point of the siphon channel, and is discharged from the first outlet. The volume of the second portion of liquid added to the container can be controlled to be less than the threshold, so that the second portion of liquid in the container cannot be discharged from the siphon channel. After the second portion of liquid stays in the container for a preset time, the opening and closing structure is controlled to open so that the second portion of liquid is discharged from the second outlet.

[0012] The siphon device facilitates the rapid flow of liquid in the liquid cup, reducing the amount of liquid remaining in the liquid cup and minimizing the impact on the liquid exiting the second outlet. On the other hand, the rapid flow of liquid towards the siphon device reduces the pressure on the second outlet and improves the stability of the opening and closing structure of the second outlet.

[0013] Furthermore, the liquid dispensing device also includes:

[0014] The first cup body, and the first liquid outlet is correspondingly provided to the first cup body;

[0015] A negative pressure component is connected to the liquid-containing cup and the first cup body respectively, so as to create a negative pressure in the liquid-containing cup and the first cup body.

[0016] In the above process, the negative pressure component creates a negative pressure state between the liquid-containing cup and the first cup body. This promotes pressure balance between them, facilitating rapid drainage from the first outlet via the siphon device and reducing liquid residue during drainage, thus minimizing the impact on the liquid exiting the second outlet. Furthermore, it promotes liquid flow towards the first outlet, reducing pressure at the second outlet and lowering the requirements for the liquid to be drained. For example, the liquid can be cold water, hot water, or water at different temperatures, avoiding the influence of liquid temperature on the pressure between the liquid-containing cup and the first cup body, thereby facilitating automatic drainage by the siphon device.

[0017] Furthermore, the negative pressure assembly includes a three-way valve and a suction device;

[0018] The three-way connector includes a first interface, a second interface, and a third interface, and the suction device includes a first connection port and a second connection port;

[0019] The first interface is connected to the liquid-containing cup, the second interface is connected to the first cup body, the third interface is connected to the first connection port, and the suction device is used to create a negative pressure in the liquid-containing cup and the first cup body.

[0020] In the above process, when the suction device operates to draw air, a negative pressure is formed inside the liquid-holding cup. When the negative pressure inside the liquid-holding cup reaches the opening pressure of the first one-way valve, the first one-way valve opens, allowing the liquid in the brewing cup to be discharged into the liquid-holding cup through the drain port. Since the suction device simultaneously draws air from both the liquid-holding cup and the first cup body, the pressure inside the liquid-holding cup and the first cup body becomes consistent. This promotes pressure balance between the liquid-holding cup and the first cup body, facilitates rapid drainage from the first drain port by the siphon device, and helps reduce liquid residue when draining through the first drain port, thus reducing the impact on the liquid exiting the second outlet. Furthermore, it promotes liquid flow towards the first outlet, reducing the pressure at the second outlet, and lowers the requirements for the liquid to be drained.

[0021] Furthermore, the second one-way valve of the opening and closing structure, and the suction device are used to create positive pressure in the liquid-containing cup and the first cup body, and to open the second one-way valve when the pressure reaches the opening pressure of the second one-way valve, so that the liquid in the liquid-containing cup is discharged into the second cup body through the second outlet.

[0022] In the above process, by controlling the amount of liquid added to the liquid cup, the amount of liquid is made less than the threshold, that is, the height of the liquid is lower than the highest point of the siphon channel, and the liquid in the liquid cup cannot be discharged from the siphon channel. At this time, the liquid stays in the liquid cup for a preset time. By blowing positive pressure air into the liquid cup through the suction device, the opening and closing structure is controlled to open, so that the liquid can be quickly discharged from the second liquid outlet.

[0023] Furthermore, the liquid-holding cup has a water outlet channel;

[0024] The opening and closing structure includes a valve core, which is connected to an elastic element;

[0025] The valve core is provided with a drain channel, and the drain channel has a liquid inlet;

[0026] The valve core is connected to the drive assembly, which drives the valve core to move toward the top of the liquid cup so that the liquid inlet protrudes from the water outlet channel and communicates with the liquid cup.

[0027] The elastic element is used to apply a force to the valve core, moving it away from the top of the liquid cup, so that the liquid inlet is submerged in the water outlet channel and blocked.

[0028] In the above implementation process, when it is necessary to open the water outlet channel to discharge liquid, the valve core is simply driven by the drive component to move towards the top of the liquid cup within the water outlet channel, causing the inlet to protrude from the water outlet channel. After the inlet protrudes from the water outlet channel, the liquid in the liquid cup can enter the drain channel from the inlet and then be discharged from the drain channel. This operation is convenient and does not require a power source. When the external force of the drive component is removed, the valve core moves downward under the action of the elastic element, that is, moves away from the top of the liquid cup, causing the inlet to enter the water outlet channel, thereby allowing the water outlet channel to block the inlet.

[0029] Furthermore, the bottom of the liquid-holding cup is provided with a bottom cover, the bottom cover is connected to the liquid-holding cup, and an installation cavity is formed between the liquid-holding cup and the bottom cover;

[0030] The mounting cavity is provided with a spring pressure plate, and the end face of the spring pressure plate facing the liquid cup has a groove.

[0031] The valve core is connected to the spring pressure plate, and the elastic element is disposed in the groove.

[0032] In the above process, when the spring plate moves upward toward the top of the liquid-holding cup under the drive assembly, it compresses the elastic element. When the force exerted by the drive assembly on the spring plate is removed, the valve core rebounds under the elastic force of the elastic element, moving downward away from the top of the liquid-holding cup. The sealing ring fixed to the valve core seals the gap between the valve core and the water outlet channel, allowing water to be stored in the liquid-holding cup. That is, when it is necessary to open the second outlet, it is only necessary to drive the valve core to move within the water outlet channel via the drive assembly; the operation is convenient and does not require a power source.

[0033] Furthermore, the drive assembly includes a pry member and a pressing member, the pry member and the pressing member being detachably connected; and / or,

[0034] The prying element is rotatably connected to the bottom cover; and / or,

[0035] The prying element abuts against the spring pressure plate.

[0036] In the above process, when it is necessary to open the water outlet channel to discharge the liquid, it is only necessary to drive the pressing part with external force to make the top part of the prying part push the boss towards the top of the liquid cup. After the inlet protrudes from the water outlet channel, the liquid in the liquid cup can enter the drain channel from the inlet and then be discharged from the drain channel. When the external force is removed, the valve core moves downward under the action of the elastic element, that is, moves away from the top of the liquid cup, so that the inlet enters the water outlet channel, thereby blocking the inlet of the water outlet channel.

[0037] Furthermore, one of the prying member and the pressing member is provided with a slot, and the other of the prying member and the pressing member is provided with a locking block, the locking block engaging with the slot.

[0038] In the above implementation process, the prying component and the pressing component can be detached, facilitating the replacement of the pressing component. The pressing component can be rod-shaped, and its length can be changed as needed, as long as the end of the pressing component connected to the prying component can engage with the prying component.

[0039] Furthermore, the siphon device includes a liquid outlet pipe and an isolation cover. The liquid outlet pipe extends upward from the first liquid outlet inside the liquid cup, and the isolation cover is inverted and placed over the liquid outlet pipe.

[0040] A bottom channel is formed between the isolation cover and the liquid cup, a side channel is formed between the isolation cover and the liquid outlet pipe, and a top channel is formed between the top of the liquid outlet pipe and the top wall of the isolation cover.

[0041] The bottom channel, the side channel, the top channel, and the outlet pipe are connected in sequence to form a siphon channel.

[0042] In the above process, under the action of the siphon principle, the liquid sequentially passes through the bottom channel, side channel, and top channel into the top of the outlet pipe, and exits from the bottom of the outlet pipe into the first cup. By controlling the amount of liquid added to the container, when the liquid level in the container reaches or exceeds the highest point of the siphon channel, the liquid sequentially passes through the bottom channel, side channel, and top channel into the top of the outlet pipe, and exits from the bottom of the outlet pipe into the first cup. By controlling the amount of liquid added to the container, when the liquid level in the container is below the highest point of the siphon channel, the liquid cannot exit from the siphon channel. At this time, the liquid can be discharged into the second cup through the second outlet for the user to drink. On the one hand, this facilitates rapid liquid flow, reduces the amount of liquid remaining in the container, and reduces the impact on the liquid exiting from the second outlet; on the other hand, the rapid flow of liquid towards the siphon device reduces the pressure on the second outlet, improving the stability of the opening and closing structure of the second outlet.

[0043] Furthermore, the liquid dispensing device also includes a brewing cup, the bottom of which is detachably connected to the top of the liquid holding cup.

[0044] The above implementation process facilitates the disassembly and installation of the liquid holding cup and the brewing cup, and has the advantages of simple structure, reliable connection, and convenient assembly and disassembly.

[0045] Furthermore, the first cup body includes a cup body and a cup lid, wherein the cup lid is detachably connected to the cup body;

[0046] The outer wall of the cup lid is provided with a mounting groove, and a first cup body sealing element is provided in the mounting groove. The first cup body sealing element is used to abut against the inner wall of the cup body.

[0047] In the above process, the sealing performance of the first cup can be improved, so that a sealed cavity can be formed inside the first cup.

[0048] Furthermore, the cup lid is provided with a liquid inlet, and the liquid inlet is provided with a first cup body lid seal, the top of which is detachably connected to the first liquid outlet.

[0049] In the above process, when it is necessary to pour out the liquid in the first cup, the top of the first cup lid seal can be separated from the first liquid outlet, so that the cup body and the cup lid of the first cup can be removed at the same time.

[0050] A second aspect of this disclosure provides a brewing apparatus, including the liquid dispensing device described in the first aspect.

[0051] A third aspect of this disclosure provides a brewing method using the dispensing device described in the first aspect or the brewing device described in the second aspect, comprising the steps of:

[0052] S100. Add liquid to the liquid container, control the opening and closing structure to close so that the liquid in the liquid container is discharged from the first liquid outlet through the siphon device, or control the opening and closing structure to open so that the liquid is discharged from the second liquid outlet.

[0053] In the above process, the siphon device facilitates the rapid flow of liquid in the liquid cup, reduces the amount of liquid remaining in the liquid cup, and reduces the impact on the liquid exiting the second outlet. On the other hand, the rapid flow of liquid to the siphon device reduces the pressure on the second outlet and improves the stability of the opening and closing structure of the second outlet.

[0054] Furthermore, the step of closing the control opening and closing structure to allow the liquid in the liquid-containing cup to be discharged from the first outlet via the siphon device also includes:

[0055] S200. Air is drawn from the liquid-containing cup and the first cup body by the suction device to create negative pressure in both the liquid-containing cup and the first cup body, so that the liquid in the liquid-containing cup is discharged from the first outlet to the first cup body through the siphon device.

[0056] In the above implementation process, when the suction device operates to draw air, negative pressure is formed inside both the liquid-containing cup and the first cup. This promotes pressure balance between the liquid-containing cup and the first cup, facilitating rapid drainage from the first outlet via the siphon device and reducing liquid residue during drainage, thus minimizing the impact on the liquid exiting the second outlet. Furthermore, it promotes liquid flow towards the first outlet, reducing pressure at the second outlet. Additionally, it lowers the requirements for the required drainage liquid, which is beneficial for siphon drainage. Further, the step of controlling the opening of the opening and closing structure also includes:

[0057] S300. Air is added to the liquid container by a suction device to create a positive pressure inside the liquid container so that the second one-way valve opens and the liquid is discharged from the second outlet.

[0058] In the above process, positive pressure air is blown into the liquid cup by the suction device to control the opening and closing structure to open, so that the liquid can be quickly discharged from the second outlet.

[0059] Furthermore, the steps of adding liquid to the liquid-containing cup, controlling the opening and closing structure to close so that the liquid in the liquid-containing cup is discharged from the first liquid outlet through the siphon device, or controlling the opening and closing structure to open so that the liquid is discharged from the second liquid outlet, include:

[0060] S100' Add liquid to the brewing cup. Use a suction device to draw air from the liquid holding cup and the first cup to create negative pressure in both the liquid holding cup and the first cup, so that the liquid in the brewing cup can be added to the liquid holding cup. Control the opening and closing structure to close so that the liquid in the liquid holding cup can be discharged from the first liquid outlet through the siphon device, or control the opening and closing structure to open so that the liquid can be discharged from the second liquid outlet.

[0061] In the above implementation process, the siphon device evacuates air from the liquid-containing cup and the first cup, creating negative pressure in both. This facilitates rapid liquid flow within the liquid-containing cup, reducing residual liquid and minimizing its impact on the liquid exiting the second outlet. Furthermore, the rapid flow of liquid towards the siphon device reduces pressure on the second outlet, improving the stability of its opening and closing structure. The negative pressure within the liquid-containing cup also facilitates the entry of liquid from the brewing cup into the liquid-containing cup. Further steps include:

[0062] S101. Control the amount of the first liquid added to the liquid container so that the amount of the first liquid is less than a threshold so that the first liquid in the liquid container cannot be discharged from the siphon channel.

[0063] S102. Control the first portion of liquid to remain in the liquid container for a preset time;

[0064] S103, control the opening and closing structure to open so that the first portion of liquid is discharged from the second outlet.

[0065] In the above process, the brewing time can be controlled by allowing the liquid to remain in the container for a preset period of time. The first portion of liquid remaining in the container can be heated or cooled to obtain a beverage at a suitable temperature.

[0066] Furthermore, it also includes the following steps:

[0067] S101': Control the opening and closing structure to open, and control the first portion of liquid to be added to the liquid container;

[0068] S103' Control the first portion of liquid to be discharged from the second outlet.

[0069] In the above process, the opening and closing structure opens, and the first liquid can be discharged from the second outlet.

[0070] Furthermore, it also includes the following steps:

[0071] S106. Control the amount of the second liquid added to the liquid container to make the amount of the second liquid greater than the threshold, so that the second liquid in the liquid container enters along the inlet of the siphon channel, flows along the siphon channel, passes through the highest point of the siphon channel, and is discharged from the first outlet.

[0072] During the above process, the second liquid can be discharged from the first outlet.

[0073] Further steps include:

[0074] S104. Control the amount of the first liquid added to the liquid container to make the amount of the first liquid greater than the threshold, so that the first liquid in the liquid container enters along the inlet of the siphon channel, flows along the siphon channel, passes through the highest point of the siphon channel, and is discharged from the first outlet.

[0075] S105. Control the amount of the second liquid added to the liquid container to make the amount of the second liquid less than the threshold so that the second liquid in the liquid container cannot be discharged from the siphon channel; after the second liquid stays in the liquid container for a preset time, control the opening and closing structure to open so that the second liquid is discharged from the second outlet.

[0076] In the above-described process, by controlling the amount of liquid added to the container, the liquid can be discharged from either the first or second outlet, thereby achieving the technical effect of obtaining different amounts of liquid from the two outlets. Additional aspects and advantages of this disclosure will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0077] Furthermore, it also includes the following steps:

[0078] S104. Control the amount of the first liquid added to the liquid container to make the amount of the first liquid greater than the threshold, so that the first liquid in the liquid container enters along the inlet of the siphon channel, flows along the siphon channel, passes through the highest point of the siphon channel, and is discharged from the first outlet.

[0079] S105. Control the opening and closing structure to open, and control the second liquid to be added into the liquid cup so that the second liquid is discharged from the second liquid outlet.

[0080] In the above implementation process, by controlling the amount of the first liquid added to the container, the liquid can be discharged from the first outlet; by controlling the opening and closing structure to open, the second liquid can be discharged from the second outlet, thus achieving the technical effect of two discharges from two outlets respectively.

[0081] Furthermore, the temperature of the first liquid is lower than the temperature of the second liquid.

[0082] In the above process, a low-temperature-high-temperature soaking is implemented. At this time, the substance to be brewed can be soaked twice at different temperatures and automatically drained to obtain beverages with different extract concentrations, different tastes, or different extracts.

[0083] Furthermore, if the substance to be brewed is coffee, the caffeine concentration of the beverage obtained after brewing the substance with the first batch of liquid is greater than that of the beverage obtained after brewing the substance with the second batch of liquid.

[0084] In the above process, the first brewing liquid is discharged as waste liquid, and only the liquid from the second brewing is retained for drinking, which can improve the taste of the beverage. For example, if the beverage to be brewed is coffee, a low-caffeine beverage can be obtained.

[0085] Additional aspects and advantages of this disclosure will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0096] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0097] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0098] Brewing devices typically include a dispensing device. They can be used to brew coffee, tea, and other beverages. When brewing twice or more, waste liquid needs to be collected in a cup and discarded before using the next cup to dispense the drinkable liquid. For example, one method of brewing coffee involves using room temperature or cold water for the first brew, then discarding the liquid to brew a second cup. This process is cumbersome and prone to spillage during the discarding process, making it inconvenient. When the brewing device has multiple dispensing outlets, the user needs to manually select the appropriate outlet. Traditional brewing devices are complex to operate and prone to human error.

[0099] Based on this, the present disclosure provides a liquid dispensing device and a brewing device using the liquid dispensing device.

[0100] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the liquid dispensing device provided in this embodiment includes a liquid cup 10 for receiving liquid. The liquid cup 10 has a first liquid outlet 101 and a second liquid outlet 102 at its bottom. The first liquid outlet 101 is provided with a siphon device, and the second liquid outlet 102 is provided with an opening and closing structure. When the liquid in the liquid cup 10 is discharged through the siphon device, the opening and closing structure closes.

[0101] Adding liquid to the liquid container 10 and closing the opening and closing mechanism allows the liquid in the liquid container 10 to be discharged from the first liquid outlet 101 via a siphon device. When liquid needs to be discharged from the second liquid outlet 102, simply open the opening and closing mechanism, and the liquid will be discharged from the second liquid outlet 102 under the action of gravity.

[0102] By controlling the amount of liquid added to the liquid container 10, the amount of liquid is made greater than the threshold, that is, the height of the liquid is higher than the highest point of the siphon channel. The liquid in the liquid container 10 enters along the inlet of the siphon channel, flows along the siphon channel, passes the highest point of the siphon channel, and is discharged from the first outlet 101.

[0103] By controlling the amount of liquid added to the liquid cup 10, the amount of liquid is made less than the threshold, that is, the height of the liquid is lower than the highest point of the siphon channel, and the liquid in the liquid cup 10 cannot be discharged from the siphon channel. At this time, the liquid stays in the liquid cup 10 for a preset time. Controlling the opening and closing structure to open can allow the liquid to be discharged from the second liquid outlet 102.

[0104] When adding liquid twice in sequence, the volume of the first portion of liquid added to the container 10 can be controlled to be greater than a threshold, so that the first portion of liquid in the container 10 enters along the inlet of the siphon channel, flows along the siphon channel, passes through the highest point of the siphon channel, and is discharged from the first outlet 101. The volume of the second portion of liquid added to the container 10 can be controlled to be less than the threshold, so that the second portion of liquid in the container 10 cannot be discharged from the siphon channel. After the second liquid stays in the container 10 for a preset time, the opening and closing structure is controlled to open so that the second portion of liquid is discharged from the second outlet 102.

[0105] The siphon device facilitates the rapid flow of liquid in the liquid cup 10, reduces the amount of liquid remaining in the liquid cup 10, and reduces the impact on the liquid exiting the second liquid outlet 102. On the other hand, the rapid flow of liquid to the siphon device reduces the pressure on the second liquid outlet 102 and improves the stability of the opening and closing structure of the second liquid outlet 102.

[0106] The opening and closing mechanism can be opened automatically or manually.

[0107] In some specific embodiments, the liquid dispensing device further includes: a first cup body 2 and a negative pressure component, wherein a first liquid outlet 101 is correspondingly provided with the first cup body 2; the negative pressure component is connected to the liquid holding cup 10 and the first cup body 2 respectively, so that a negative pressure is formed in the liquid holding cup 10 and the first cup body 2.

[0108] The negative pressure component creates a negative pressure state within the liquid-containing cup 10 and the first cup body 2. This promotes pressure balance between the two, facilitating rapid drainage from the first outlet via the siphon device and reducing liquid residue during drainage, thus minimizing the impact on the liquid exiting the second outlet. Furthermore, it promotes liquid flow towards the first outlet 101, reducing pressure at the second outlet. Additionally, it lowers the requirements for the liquid to be drained. For example, the liquid can be cold water, hot water, or water at different temperatures, avoiding the influence of liquid temperature on the pressure between the liquid-containing cup 10 and the first cup body 2, thereby facilitating automatic drainage by the siphon device.

[0109] In some specific embodiments, the negative pressure assembly includes a three-way valve 7 and a suction device; the three-way valve 7 includes a first interface 71, a second interface 72 and a third interface 73, and the suction device includes a first connection port 81 and a second connection port 82; the first interface 71 is connected to the liquid cup 10, the second interface 72 is connected to the first cup body 2, and the third interface 73 is connected to the first connection port 81, and the suction device is used to create negative pressure in the liquid cup 10 and the first cup body 2.

[0110] When the suction device operates, a negative pressure is created inside the liquid-holding cup 10. When the negative pressure inside the liquid-holding cup 10 reaches the opening pressure of the first one-way valve, the first one-way valve opens, allowing the liquid in the brewing cup to drain into the liquid-holding cup 10 through the drain port. Since the suction device simultaneously evacuates air from both the liquid-holding cup 10 and the first cup body, the pressure inside the liquid-holding cup 10 and the first cup body becomes consistent. This promotes pressure balance between the liquid-holding cup 10 and the first cup body, facilitates rapid drainage from the first drain port by the siphon device, and helps reduce liquid residue when draining through the first drain port, thus reducing the impact on the liquid exiting the second outlet 102. Furthermore, it promotes liquid flow towards the first outlet 101, reducing the pressure at the second outlet 102, and lowering the requirements for the liquid to be drained.

[0111] In some specific embodiments, the opening and closing structure includes a second one-way valve 19. The suction device is used to create a positive pressure in the liquid cup 10 and the first cup body 2 and to open the second one-way valve 19 when the pressure reaches the opening pressure of the second one-way valve 19, so that the liquid in the liquid cup 10 is discharged into the second cup body 4 through the second outlet 102.

[0112] By controlling the amount of liquid added to the liquid cup 10, the amount of liquid is made less than the threshold, that is, the height of the liquid is lower than the highest point of the siphon channel, and the liquid in the liquid cup 10 cannot be discharged from the siphon channel. At this time, the liquid is controlled to stay in the liquid cup 10 for a preset time. By blowing positive pressure air into the liquid cup 10 through the suction device, the opening and closing structure is controlled to open, so that the liquid can be quickly discharged from the second liquid outlet 102.

[0113] Combination Figure 4 and Figure 5As shown, the liquid-containing cup 10 has a water outlet channel. The opening and closing structure includes a valve core 13, which is connected to an elastic element 14. The valve core 13 has a drain channel 132 with an inlet 131. The valve core 13 is connected to a drive assembly, which drives the valve core 13 to move towards the top of the liquid-containing cup 10, so that the inlet 131 protrudes from the water outlet channel and communicates with the liquid-containing cup 10. When the inlet 131 protrudes from the water outlet channel, the liquid in the liquid-containing cup 10 can enter the drain channel 132 from the inlet 131 and then be discharged from the drain channel 132. Optionally, the drive assembly is connected to the valve core 13 and drives the valve core 13 to slide up and down in the water outlet channel, so that the valve core 13 opens or closes the water outlet channel. When it is necessary to open the water outlet channel to discharge the liquid, simply drive the valve core 13 to move towards the top of the liquid cup 10 in the water outlet channel through the drive component, so that the liquid inlet 131 protrudes out of the water outlet channel. After the liquid inlet 131 protrudes out of the water outlet channel, the liquid in the liquid cup 10 can enter the liquid discharge channel 132 from the liquid inlet 131 and then be discharged from the liquid discharge channel 132. The operation is convenient and does not require a power supply 56.

[0114] The elastic element 14 applies a force to the valve core 13, moving it away from the top of the liquid cup 10, so that the inlet 131 is submerged in the outlet channel and blocked. When it is necessary to open the outlet channel to allow the liquid in the liquid cup 10 to be discharged from the second outlet 102, the valve core 13 is moved towards the top of the liquid cup 10 within the outlet channel by an external force, so that the inlet 131 protrudes out of the outlet channel. After the inlet 131 protrudes out of the outlet channel, the liquid in the liquid cup 10 can enter the drain channel 132 from the inlet 131 and then be discharged from the drain channel 132. When the external force of the driving component is removed, the valve core 13 moves downward under the action of the elastic element 14, that is, moves away from the top of the liquid cup 10, so that the inlet 131 enters the outlet channel, thereby blocking the inlet 131 in the outlet channel.

[0115] Optionally, the valve core 13 is provided with a sealing ring, which can abut against the side wall of the water outlet channel to seal the liquid inlet 131, thereby improving the sealing performance between the valve core 13 and the water outlet channel. Optionally, the sealing ring can also be other sealing materials or sealing structures that can achieve a sealing effect. Optionally, the sealing ring is an O-ring. Optionally, along the sliding direction of the valve core 13, the valve core 13 is provided with multiple sealing rings, which are spaced apart to improve the sealing performance between the valve core 13 and the water outlet channel.

[0116] Optionally, the elastic element 14 can be a spring, a metal sheet, an elastic rubber component, or other elastic objects.

[0117] In some specific embodiments, the bottom of the liquid cup 10 is provided with a bottom cover 18, which is connected to the liquid cup 10, forming an installation cavity between the liquid cup 10 and the bottom cover 18. A water outlet channel is formed at the bottom of the liquid cup 10, and the valve core 13 is disposed in the installation cavity. A spring pressure plate 15 is provided in the installation cavity, which is connected to the valve core 13 and is movably disposed on the bottom cover 18. The end face of the spring pressure plate 15 facing the liquid cup 10 has a groove 151 that is recessed towards the bottom cover 18. The bottom of the valve core 13 is connected to the spring pressure plate 15, and an elastic element 14 is disposed in the groove 151. The elastic element 14 is used to apply a force to the spring pressure plate 15 to move it away from the top of the liquid cup 10, so that the liquid inlet 131 can be submerged in the water outlet channel and blocked.

[0118] Optionally, the bottom cover 18 is provided with a second channel, which is opposite to the water outlet channel. A valve core for opening or closing the water outlet channel is provided between the water outlet channel and the second channel. When it is necessary to discharge liquid from the liquid cup 10 through the second liquid outlet 102, simply drive the spring plate 15 with external force to move the valve core 13 toward the top of the liquid cup 10, so that the liquid inlet 131 protrudes into the water outlet channel. This is convenient to operate and does not require a power supply 56. When the external force of the driving component is removed, the valve core 13, under the action of the elastic element 14, pushes the spring plate 15 and the valve core 13 together to move downward, that is, to move away from the top of the liquid cup 10, so that the liquid inlet 131 enters the water outlet channel, thereby allowing the water outlet channel to block the liquid inlet 131.

[0119] Optionally, the valve core 13 is provided with a stop at the top, so that the valve core 13 can slide up and down in the water outlet channel. The stop is used to abut against the inner surface of the bottom of the liquid cup 10 to prevent the valve core 13 from detaching from the water outlet channel.

[0120] In some specific embodiments, the groove 151 may form a receiving space for accommodating the elastic element 14. The elastic element 14 is sleeved on the valve core 13 for applying movement to the spring pressure plate 15 in a direction away from the top of the liquid cup 10. The bottom cover 18 has a second channel in which the spring pressure plate 15 can slide.

[0121] When the elastic element 14 is a spring, the spring is sleeved on the valve core 13, one end of the spring is connected to the spring pressure plate 15, and the other end is connected to the bottom of the liquid cup 10 or the water outlet channel at the bottom of the liquid cup 10.

[0122] When the spring plate 15 moves upward toward the top of the liquid cup 10 under the drive of the drive assembly, it compresses the spring. When the force exerted by the drive assembly on the spring plate 15 is removed, the valve core 13 rebounds under the spring force and moves downward away from the top of the liquid cup 10. The sealing ring fixed to the valve core 13 seals the valve core 13 with the water outlet channel, allowing water to be stored in the liquid cup 10. That is, when it is necessary to open the second outlet 102, it is only necessary to drive the valve core 13 to move within the water outlet channel via the drive assembly; the operation is convenient and does not require a power supply 56.

[0123] When it is necessary to open the water outlet channel to allow the liquid in the liquid cup 10 to be discharged from the second outlet 102, simply drive the spring plate 15 with external force. The spring plate 15 will cause the valve core 13 to move towards the top of the liquid cup 10 in the water outlet channel, so that the inlet 131 protrudes out of the water outlet channel. After the inlet 131 protrudes out of the water outlet channel, the liquid in the liquid cup 10 can enter the drain channel 132 from the inlet 131 and then be discharged from the drain channel 132. When the external force is removed, the spring plate 15 moves downward under the action of the elastic element 14. The valve core 13 and the spring plate 15 move downward at the same time, that is, the valve core 13 moves away from the top of the liquid cup 10, so that the inlet 131 enters the water outlet channel, thereby allowing the water outlet channel to block the inlet 131.

[0124] In some specific embodiments, the drive assembly includes a pry member 16 and a pressing member 17, which are detachably connected; and / or, the pry member 16 is rotatably connected to the bottom cover 18; and / or, the pry member 16 abuts against the spring pressure plate 15, allowing the drive assembly to pry the spring pressure plate 15 according to the lever principle. Specifically, the outer wall of the groove 151 is provided with a boss that extends circumferentially along the outer wall, and the pry member 16 has a pushing portion that abuts against the boss; the bottom cover 18 is provided with a mounting hole 182, through which the pressing member 17 extends out of the mounting cavity.

[0125] When it is necessary to open the water outlet channel to discharge liquid, simply drive the pressing member 17 with external force, causing the pushing part of the prying member 16 to push the boss towards the top of the liquid cup 10. After the inlet 131 protrudes from the water outlet channel, the liquid in the liquid cup 10 can enter the drain channel 132 from the inlet 131 and then be discharged from the drain channel 132. When the external force is removed, the valve core 13 moves downward under the action of the elastic member 14, that is, moves away from the top of the liquid cup 10, so that the inlet 131 enters the water outlet channel, thereby blocking the inlet 131 in the water outlet channel.

[0126] The push-up part includes a first push rod and a second push rod; both the first push rod and the second push rod abut against the boss, and the first push rod and the second push rod are located on both sides of the spring pressure plate 15 in the axial direction, so that the force on the spring pressure plate 15 is consistent on both sides, which facilitates the valve core 13 to move up and down in the water outlet channel.

[0127] Optionally, the prying member 16 has a first hinge portion, and the bottom cover 18 has a second hinge portion. The first hinge portion and the second hinge portion are hinged together, allowing the drive assembly to pry the spring pressure plate 15 according to the lever principle, causing the spring pressure plate 15 to move towards the top of the liquid cup 10. Optionally, one of the first hinge portion and the second junction portion is a support, and the other of the first hinge portion and the second junction portion is a hinge shaft. The hinge shaft is rotatably mounted on the support, and the hinge shaft can be the aforementioned rotating shaft 181. The position of the support can serve as the fulcrum of the drive assembly, so that when the pressing member 17 moves downward, the pushing portion of the prying member 16 can move upward.

[0128] Optionally, the bottom cover 18 is provided with a support, and the support is provided with a rotating shaft 181. The prying member 16 is rotatably connected to the rotating shaft 181. The drive assembly can press the prying member 16 by pressing the pressing member 17 according to the lever principle, so that the spring pressure plate 15 moves toward the top of the liquid cup 10.

[0129] In some specific embodiments, one of the prying member 16 and the pressing member 17 is provided with a slot 171, and the other of the prying member 16 and the pressing member 17 is provided with a locking block 161, which engages with the slot 171. Because the locking block engages with the slot 171, the prying member 16 and the pressing member 17 can be disassembled, facilitating the replacement of the pressing member 17. The pressing member 17 can be rod-shaped, and its length can be varied as needed, as long as the end of the pressing member 17 connected to the prying member 16 can engage with the prying member 16.

[0130] like Figure 5 As shown, a slot 171 is provided on the pressing member 17, and a locking block 161 is provided on the prying member 16. One, two, three, or more slots 171 can be provided. When one slot 171 is provided, one locking block 161 is also provided, and the slot 171 engages with the locking block 161. When two slots 171 are provided, two locking blocks 161 are also provided, with each slot 171 corresponding to one of the locking blocks 161. When three or more slots 171 are provided, three or more locking blocks 161 are also provided, with each slot 171 corresponding to one of the locking blocks 161. Preferably, the prying member 16 has two opposing locking blocks 161, and the slot 171 engages with each locking block 161, allowing for the detachability of the prying member 16 and the pressing member 17, and offering the advantages of simple structure and easy assembly / disassembly.

[0131] Optionally, the side wall of the bottom cover 18 is provided with a mounting hole 182, through which the pressing member 17 can pass and connect with the prying member 16. When the pressing member 17 needs to be replaced, it is easy to replace the pressing member 17 since it is detachably connected to the prying member 16. The length of the pressing member 17 can be changed as needed, as long as the end of the pressing member 17 connected to the prying member 16 can be engaged with the prying member 16.

[0132] Optionally, the press element 17 is equipped with a button, which can be made of a flexible material to make it more comfortable to hold.

[0133] Optionally, the pressing part 17 includes a pressing part and a connecting part. The connecting part is provided with a locking block or a locking groove 171. The pressing part is located at one end of the setting button. The area of ​​the pressing part is larger than the area of ​​the connecting part, making it easier to hold and convenient to press.

[0134] In some specific embodiments, the bottom of the brewing cup 32 is detachably connected to the top of the liquid container 10. Figure 4 and Figure 5 As shown, the bottom of the brewing cup 32 is provided with an external thread, and the top of the liquid holding cup 10 is provided with an internal thread. The bottom of the brewing cup 32 and the top of the liquid holding cup 10 are threadedly connected, which facilitates the disassembly and installation of the liquid holding cup 10 and the brewing cup 32. It has the advantages of simple structure, reliable connection and convenient assembly and disassembly.

[0135] In some specific embodiments, the bottom of the brewing cup 32 is detachably connected to the top of the liquid container 10. After the brewing cup 32 is connected to the liquid container 10, the liquid in the brewing cup 32 can flow into the liquid container 10 from the drain port.

[0136] The liquid cup 10 is provided with a stepped part, and the stepped part is provided with a liquid cup sealing element 11. When the bottom of the brewing cup 32 is threadedly connected to the top of the liquid cup 10, the bottom surface of the bottom of the brewing cup 32 can abut against the liquid cup sealing element 11, thereby achieving a seal between the brewing cup 32 and the liquid cup 10, so that a sealed cavity can be formed inside the liquid cup 10.

[0137] The liquid-filled cup seal 11 can be a sealing ring, or other sealing materials or sealing structures that can achieve a sealing effect. Optionally, the liquid-filled cup seal 11 is an O-ring.

[0138] In some specific embodiments, the first cup body 2 includes a cup body 21 and a cup lid 22, which are detachably connected to the cup body 21. The outer wall of the cup lid 22 has a mounting groove, within which a first cup body sealing element 23 is installed. The first cup body sealing element 23 abuts against the inner wall of the cup body 21, improving the sealing performance of the first cup body 2 and forming a sealed cavity within it. Figure 4 and Figure 5As shown, the first cup body seal 23 is installed in the mounting groove. Optionally, the first cup body seal 23 includes a first lip and a second lip, which are spaced apart along the height direction. Both the first lip and the second lip abut against the first cup body 2, allowing the first cup body 2 to form a sealed cavity. The first lip and the second lip fit more easily with the first cup body 2, thereby improving the sealing performance and enabling the first cup body 2 to form a stable sealed cavity. The first cup body seal 23 can be a sealing ring, or other sealing materials or sealing structures that can achieve a sealing effect.

[0139] When the first cup body 2 needs to be cleaned, the cup lid 22 can be removed from the first cup body 2 for easy cleaning.

[0140] In some specific embodiments, the cup lid 22 is provided with a liquid inlet, and the liquid inlet is provided with a first cup body cover seal 24. The first cup body cover seal 24 is installed on the liquid inlet and fixed to the cup lid 22. The top of the first cup body cover seal 24 is detachably connected to the first liquid outlet 101. When it is necessary to pour out the liquid in the first cup body 2, the top of the first cup body cover seal 24 can be separated from the first liquid outlet 101, so that the cup body 21 and the cup lid 22 of the first cup body 2 can be removed at the same time.

[0141] Optionally, the first outlet 101 has an extension tube 63 that connects to the outlet pipe 61 and extends downward from the first outlet 101 in a direction away from the top of the liquid container 10. The top of the first cup body cap seal 24 is detachably connected to the extension tube 63. Simultaneously, the first cup body cap seal 24 can be sealed to the extension tube 63, allowing sealed cavities to be formed inside both the first cup body 2 and the second cup body 4. Optionally, the first cup body cap seal 24 includes a third lip that fits against the outer wall of the extension tube 63, allowing sealed cavities to be formed inside both the first cup body 2 and the second cup body 4. When it is necessary to pour out the liquid in the first cup body 2, the top of the first cup body cover seal 24 can be separated from the first liquid outlet 101, so that the cup body 21 and the cup cover 22 of the first cup body 2 can be taken out at the same time. Since the third lip covers the extension tube 63, when the third lip is made of soft material, it is easy for the third lip to separate from the extension tube 63, so that the cup body 21 and the cup cover 22 of the first cup body 2 can be taken out at the same time.

[0142] The liquid cup lid seal 24 can be a sealing ring, or other sealing materials or sealing structures that can achieve a sealing effect. Optionally, the liquid cup seal 11 is an O-ring.

[0143] In some specific embodiments, the siphon device includes an outlet pipe 61 and an isolation cover 62. The outlet pipe 61 extends upward from the first outlet 101 inside the liquid cup 10, and the isolation cover 62 is inverted and placed over the outlet pipe 61. A bottom channel is formed between the isolation cover 62 and the liquid cup 10, a side channel is formed between the isolation cover 62 and the outlet pipe 61, and a top channel is formed between the top of the outlet pipe 61 and the top wall of the isolation cover 62. The bottom channel, the side channel, the top channel, and the outlet pipe 61 are sequentially connected to form a siphon channel.

[0144] Under the action of the siphon principle, liquid sequentially passes through the bottom channel, side channel, and top channel into the top of the outlet pipe 61, and exits from the bottom of the outlet pipe 61 into the first cup body 2. By controlling the amount of liquid added to the liquid container 10, when the liquid level in the container reaches or exceeds the highest point of the siphon channel, the liquid sequentially passes through the bottom channel, side channel, and top channel into the top of the outlet pipe 61, and exits from the bottom of the outlet pipe 61 into the first cup body 2. By controlling the amount of liquid added to the liquid container 10, when the liquid level in the container 10 is below the highest point of the siphon channel, the liquid cannot exit from the siphon channel. At this time, the liquid can be discharged into the second cup body 2 through the second outlet 102 for the user to drink.

[0145] Optionally, a siphon device is installed in the liquid-containing cup 10, wherein the siphon channel of the siphon device connects the liquid-containing cup 10 and the first outlet 101. The inlet of the siphon channel is located at the bottom of the liquid-containing cup 10, so that the liquid in the liquid-containing cup 10 enters from the inlet, flows along the siphon channel, passes through the highest point of the siphon channel, and then exits from the first outlet 101. Preferably, the inlet of the siphon channel is located at the lowest point of the bottom of the liquid-containing cup 10. Specifically, the liquid in the liquid-containing cup 10 enters from the inlet, flows upward along the siphon channel, passes through the highest point of the siphon channel, flows downward along the siphon channel, and finally exits from the first outlet 101. The siphon device can generate a siphon effect, causing the liquid in the liquid cup 10 to be discharged from the first liquid outlet 101 through the siphon channel. On the one hand, this facilitates the rapid flow of liquid, reduces the amount of liquid remaining in the liquid cup 10, and reduces the impact on the liquid exiting the second liquid outlet 102. On the other hand, the rapid flow of liquid towards the siphon device reduces the pressure on the second liquid outlet 102 and improves the stability of the opening and closing structure of the second liquid outlet 102.

[0146] In some specific embodiments, the siphon device includes an outlet pipe 61 and an isolation cover 62. The outlet pipe 61 extends upward from the first outlet 101 within the liquid cup 10, and the isolation cover 62 is inverted and placed over the outlet pipe 61. A bottom channel is formed between the isolation cover 62 and the liquid cup 10, and the inlet of the siphon channel is located in the bottom channel. When the bottom of the isolation cover 62 is provided with an inlet hole, the bottom channel can be an inlet hole located at the bottom of the isolation cover 62. A side channel is formed between the isolation cover 62 and the outlet pipe 61. Specifically, a side channel is formed between the inner side wall of the isolation cover 62 and the outer side wall of the outlet pipe 61. A top channel is formed between the top of the outlet pipe 61 and the top wall of the isolation cover 62. The bottom channel, the side channel, the top channel, and the outlet pipe 61 are sequentially connected to form the siphon channel.

[0147] The isolation cover 62 and the liquid-holding cup 10 can be manufactured separately, reducing manufacturing difficulty. When the liquid level in the liquid-holding cup 10 is higher than the top of the liquid outlet pipe 61, a sealed space is formed between the isolation cover 62 and the liquid outlet pipe 61. When the liquid level is higher than the top of the liquid outlet pipe 61, under the action of the siphon principle, the liquid sequentially enters the top of the liquid outlet pipe 61 through the bottom channel, side channel, and top channel, and is discharged from the bottom of the liquid outlet pipe 61 into the first cup body 2. By controlling the amount of liquid added to the liquid-holding cup 10, the liquid in the liquid-holding cup 10 reaches the minimum liquid level height required to produce the siphon phenomenon. That is, when the liquid level in the liquid-holding cup 10 reaches or exceeds the top of the liquid outlet pipe 61, the liquid sequentially enters the top of the liquid outlet pipe 61 through the bottom channel, side channel, and top channel, and is discharged from the bottom of the liquid outlet pipe 61 into the first cup body 2. By controlling the amount of liquid added to the liquid container 10, the liquid in the liquid container 10 is kept below the top of the liquid outlet tube 61, so that the liquid cannot be discharged from the siphon channel. At this time, the liquid can be discharged to the second cup body 4 through the second liquid outlet 102 for the user to drink.

[0148] In other words, when the liquid level in the liquid cup 10 is higher than the top of the liquid outlet pipe 61, the liquid sequentially passes through the bottom channel, side channel, and top channel into the top of the liquid outlet pipe 61 and is discharged from the bottom of the liquid outlet pipe 61. When it is necessary to discharge the liquid in the liquid cup 10 into the first cup body 2, the controller 51 only needs to control the amount of liquid added to the liquid cup 10 so that the liquid level in the liquid cup 10 reaches or exceeds the top of the liquid outlet pipe 61, thereby creating a siphon effect in the siphon channel. The liquid sequentially passes through the bottom channel, side channel, and top channel into the top of the liquid outlet pipe 61 and is discharged from the bottom of the liquid outlet pipe 61 into the first cup body 2. On the one hand, this facilitates the rapid flow of liquid, reduces the remaining liquid in the liquid cup 10, and reduces the impact on the liquid exiting from the second liquid outlet 102; on the other hand, the rapid flow of liquid towards the siphon device reduces the pressure on the second liquid outlet 102 and improves the stability of the opening and closing structure of the second liquid outlet 102.

[0149] Optionally, the bottom of the brewing cup 32 is provided with a drain port, and the drain port is provided with a first one-way valve 33. When the first one-way valve 33 is opened, the liquid in the brewing cup 32 flows into the liquid holding cup 10 from the drain port.

[0150] The negative pressure component can create a negative pressure in the liquid cup 10 and the first cup body 2. When the negative pressure reaches the opening pressure of the first one-way valve 33, the first one-way valve 33 is opened, so that the liquid in the brewing cup 32 is discharged into the liquid cup 10 through the first one-way valve 33 of the drain port.

[0151] The first check valve 33 can be replaced by a solenoid valve, which is connected to the controller 51. The controller 51 controls whether the solenoid valve is open. The suction device can create a negative pressure in the liquid cup 10 and the first cup body 2, and when the negative pressure reaches the opening pressure of the first check valve 33, the first check valve 33 will open.

[0152] When the suction device operates to draw air, a negative pressure is formed inside the liquid container 10. When the negative pressure inside the liquid container 10 reaches the opening pressure of the first one-way valve 33, the first one-way valve 33 opens, allowing the liquid to be discharged into the liquid container 10 through the drain port. The suction device can be an air pump 8 or a suction pump 83.

[0153] The liquid dispensing device includes a liquid-holding cup assembly 1 and a controller 51. The liquid-holding cup assembly 1 includes a liquid-holding cup 10 for receiving liquid, which can be waste liquid or liquid to be consumed. The bottom of the liquid-holding cup 10 is provided with a first liquid outlet 101 and a second liquid outlet 102. The first liquid outlet 101 is used to discharge waste liquid and can be located at the bottom or side of the liquid-holding cup 10. Preferably, the first liquid outlet 101 is located at the bottom of the liquid-holding cup 10, and more preferably, it is located in the middle area of ​​the bottom of the liquid-holding cup 10. The first liquid outlet 101 is provided with a siphon device, which can quickly discharge the liquid from the liquid-holding cup 10. The first cup assembly includes a first cup body 2, which is located below the liquid-holding cup 10 and connected to the first liquid outlet 101. The siphon device can discharge the liquid from the liquid-holding cup 10 into the first cup body 2. The first cup 2 is used to store or store waste liquid, which can solve the problem of complicated operation and repeated waste liquid disposal for users.

[0154] Optionally, the second outlet 102 is used to discharge the liquid to be consumed. Preferably, the second outlet 102 is located in the middle area of ​​the bottom of the liquid-holding cup 10. The second cup body 4 is located below the liquid-holding cup and is connected to the second outlet 102. The liquid to be consumed can be discharged into the second cup body 4 through the second outlet 102. The controller 51 is used to control the amount of liquid entering the liquid-holding cup 10 so that the liquid in the liquid-holding cup 10 is discharged into the first cup body 2 through the siphon device when it exceeds the highest point of the siphon channel of the siphon device. When the first cup is finished and waste liquid needs to be discharged, the controller 51 controls the amount of liquid entering the liquid-holding cup 10 so that the liquid level in the liquid-holding cup 10 exceeds the discharge line of the siphon device. At this time, the waste liquid can be discharged into the first cup body 2 through the siphon device. When it is necessary to brew drinking water, the controller 51 controls the amount of liquid entering the liquid container 10, so that the liquid level in the liquid container 10 is lower than the highest point of the siphon device, so that the liquid will not be discharged from the first outlet 101, thus solving the problem of repeated operation to empty the waste liquid.

[0155] In one specific embodiment, the liquid dispensing device further includes a water pump 9 and an instant heating element 53. The water pump 9 is connected to a controller, which can control the amount of liquid added to the brewing cup 32 by the water pump, and thus control the amount of liquid entering the liquid container 10 from the brewing cup 32.

[0156] The instant heating element 53 can heat the liquid entering the brewing cup 32. The instant heating element 53 is connected to the controller 51. The controller 51 can control the preheating temperature of the instant heating element 53 so as to heat the liquid to be added to the liquid container 10 to the set temperature.

[0157] Optionally, the instant heating element 53 can be an electric heater.

[0158] Optionally, the instant heating element 53 is installed on the pipe connecting the outlet of the water pump 9 to the brewing cup 32.

[0159] Optionally, the instant heating unit 53 may include a water storage section. Water from the water pump 9 first enters the water storage section through the inlet, then exits through the outlet and enters the brewing cup 32. The water storage section is equipped with an electric heater. A temperature sensor is installed in the water storage section or on the pipe connected to the outlet of the water storage section. The temperature sensor is used to detect the temperature of the liquid and transmit the detected temperature information to the controller 51. The controller 51 can control the water temperature discharged from the water storage section, and thus control the water temperature entering the brewing cup 32.

[0160] The controller 51 is connected to the power supply 56. The controller 51 can control the brewing time of the brewing cup 32, the time of applying negative pressure, and the start and stop of the water pump 9, air pump 8 or suction pump 83.

[0161] like Figure 1As shown, the suction device is an air pump 8, and the liquid dispensing device includes a water tank 54, a water pump 9, an air pump 8, and an instant heater 53. The outlet of the water tank 54 is connected to the inlet of the water pump 9 via a pipe, the outlet of the water pump 9 is connected to the inlet of the instant heater 53 via a pipe, and the outlet of the instant heater 53 is connected to the inlet of the brewing cup 32 via a pipe. The first connection port 81 of the air pump 8 is connected to the third interface 73 of the tee 7 via a pipe, and the second connection port 82 of the air pump 8 is an exhaust port, which can be connected to an exhaust pipe. The first interface 71 of the tee 7 is connected to the liquid holding cup 10, and the second interface 72 of the tee 7 is connected to the first cup body 2. After the first batch of waste liquid in the brewing cup 32 is brewed, the air pump 8 operates to draw air, ensuring that the internal air pressure of the liquid container 10 and the first cup body 2 is consistent. When the pressure in the liquid container 10 reaches the opening pressure of the first one-way valve 33, the first one-way valve 33 opens, allowing the liquid in the brewing cup 32 to enter the liquid container 10. When the liquid level exceeds the siphon characteristic liquid level, i.e., the drain line, the wastewater automatically flows into the wastewater cup. The beverage can then be brewed. Since the liquid level of this brewed beverage is below the siphon liquid level, i.e., the drain line, the liquid will not be discharged from the first outlet 101 through the siphon channel. The liquid is ready to drink after being discharged through the second outlet 102 into the second cup body 4. The first cup body 2 is used to store waste liquid, solving the problem of repeated waste liquid disposal by the user.

[0162] Combination Figure 6 and Figure 7 As shown, the opening and closing structure includes a second one-way valve 19. The suction device is used to create a positive pressure in the liquid cup 10 and the first cup body 2, and when the pressure reaches the opening pressure of the second one-way valve 19, the second one-way valve 19 opens, allowing the liquid in the liquid cup 10 to be discharged into the second cup body 4 through the second outlet 102. When brewing a beverage, if the liquid volume is lower than the discharge line of the siphon device, the liquid will not be discharged from the first outlet 101 through the siphon channel. When a beverage is needed, air is blown into the liquid cup 10 through the suction device, creating a positive pressure inside the liquid cup 10. When the pressure inside the liquid cup 10 reaches the opening pressure of the second one-way valve 19, the liquid can be discharged into the second cup body 4 through the second outlet 102 for the user to drink.

[0163] In some specific embodiments, the second one-way valve 19 can be replaced by a solenoid valve, which is connected to the controller 51, which controls whether the solenoid valve is opened.

[0164] like Figure 2As shown, the suction device is a suction pump 83, and the liquid outlet device includes a water tank 54, a water pump 9, the suction pump 83, and an instant heater 53. The outlet of the water tank 54 is connected to the inlet of the water pump 9 via a pipe, the outlet of the water pump 9 is connected to the inlet of the instant heater 53 via a pipe, and the outlet of the instant heater 53 is connected to the inlet of the brewing cup 32 via a pipe. The first connection port 81 of the suction pump 83 is connected to the third interface 73 of the tee 7 via a pipe. The second connection port 82 of the suction pump 83 is an air inlet, which can be used for air intake or exhaust as needed, and can be connected to an air pipe. The first interface 71 of the tee 7 is connected to the liquid container 10, and the second interface 72 of the tee 7 is connected to the first cup body 2. After the first batch of waste liquid in the brewing cup 32 is brewed, the suction pump 83 operates to draw air, ensuring that the internal air pressure of the liquid container 10 and the first cup body 2 is consistent. When the pressure in the liquid container 10 reaches the opening pressure of the first one-way valve 33, the first one-way valve 33 opens, allowing the liquid in the brewing cup 32 to enter the liquid container 10. When the liquid level exceeds the siphon characteristic liquid level, i.e., the drain line, the wastewater automatically flows into the wastewater cup. Drinking beverages can then be brewed. The liquid volume of this brewed beverage is below the siphon liquid level, i.e., the drain line, and the liquid will not be discharged from the first outlet through the siphon channel. When liquid needs to be discharged from the liquid container 10, the suction pump 83 uses positive pressure to blow air, opening the second one-way valve 19 at the bottom of the liquid container 10 under pressure, allowing the beverage to flow into the second cup body 4, thus achieving automatic beverage dispensing. This solves the problem of users repeatedly emptying waste liquid and enables automatic beverage dispensing.

[0165] The brewing device includes a body 5, on which an operation panel 55 is provided. A controller 51 is connected to the operation panel 55, and the operation panel 55 can control the start and stop of the water pump 9, air pump 8, or suction pump 83. The operation panel 55 can also control the start and stop of the water pump 9, air pump 8, or suction pump 83 and the operation of the valves.

[0166] In some specific embodiments, the brewing cup assembly 3 includes a filter assembly 31 and a brewing cup 32, with the brewing cup 32 connected to the main body 5. Optionally, the brewing cup 32 is detachably connected to the main body 5, and the filter assembly 31 is detachably connected to the brewing cup 32. When adding ingredients, the brewing cup 32 can be removed from the main body 5, the ingredients placed in the filter assembly 31, and then the brewing cup placed back into the main body 5. When cleaning the brewing cup 32, it can be detached from the main body 5 for easy cleaning. When cleaning the filter assembly 31, it can be detached from the brewing cup 32 for easy cleaning and convenient use.

[0167] In some specific embodiments, the body 5 is provided with a water outlet 52, which is located above the brewing cup 32, so that water from the water tank 54 can enter the brewing cup 32 through the water outlet 52.

[0168] Optionally, the water outlet 52 is opposite to the mouth of the water storage cup brewing cup 32, and the water outlet 52 is connected to the end of the pipe away from the water pump 9.

[0169] In some specific embodiments, the body 5 is provided with a snap-fit ​​groove, and the top of the brewing cup 32 has a protruding part that engages with the snap-fit ​​groove, making it easy to pick up and install the brewing cup 32 and improving ease of use. Optionally, the protrusion extends circumferentially along the mouth of the brewing cup 32, and the protruding part engages with the snap-fit ​​groove.

[0170] The brewing device provided in this embodiment includes a liquid dispensing device. Since the brewing device provided in this embodiment has the same advantages as the liquid dispensing device, it will not be described again here.

[0171] This disclosure also discloses a liquid dispensing device or a brewing device, characterized by including the following steps:

[0172] S100: Add liquid to the liquid container 10, control the opening and closing structure to close so that the liquid in the liquid container 10 is discharged from the first liquid outlet 101 through the siphon device, or control the opening and closing structure to open so that the liquid is discharged from the second liquid outlet 102.

[0173] In the above process, the siphon device facilitates the rapid flow of liquid in the liquid cup 10, reduces the amount of liquid remaining in the liquid cup 10, and reduces the impact on the liquid exiting the second liquid outlet 102. On the other hand, the rapid flow of liquid to the siphon device reduces the pressure on the second liquid outlet 102 and improves the stability of the opening and closing structure of the second liquid outlet.

[0174] Furthermore, the step of controlling the opening and closing structure to close so that the liquid in the liquid cup 10 is discharged from the first outlet 101 through the siphon device also includes: S200, evacuating air from the liquid cup 10 and the first cup body 2 through the suction device to create negative pressure in both the liquid cup 10 and the first cup body 2, so that the liquid in the liquid cup 10 is discharged from the first outlet 101 to the first cup body 2 through the siphon device.

[0175] In the above-mentioned process, when the suction device works to pump air, negative pressure is formed in both the liquid cup and the first cup body. On the one hand, this promotes the pressure balance between the liquid cup 102 and the first cup body 2, promotes the rapid discharge of liquid from the first drain port 101 by the siphon device, and helps to reduce the residue of liquid when it is discharged through the first drain port 101, thus reducing the impact on the liquid discharged from the second drain port 102. On the other hand, it promotes the flow of liquid to the first drain port 101, reduces the pressure at the second drain port 102, and further reduces the requirements for the liquid to be discharged, which is beneficial to siphon discharge.

[0176] Furthermore, the steps for controlling the opening of the opening and closing structure also include:

[0177] S300. Gas is added to the liquid cup 10 by the suction device to create a positive pressure in the liquid cup 10 so that the second one-way valve 19 is opened so that the liquid is discharged from the second outlet 102.

[0178] In the above process, positive pressure air is blown into the liquid cup 10 by the suction device to control the opening and closing structure to open, so that the liquid can be quickly discharged from the second liquid outlet 102.

[0179] Furthermore, the steps of adding liquid to the liquid container 10, controlling the opening and closing mechanism to close so that the liquid in the liquid container 10 is discharged from the first liquid outlet 101 via the siphon device, or controlling the opening and closing mechanism to open so that the liquid is discharged from the second liquid outlet 102 include:

[0180] S100' Add liquid to the brewing cup. Use a suction device to draw air from the liquid holding cup 10 and the first cup body 2 to create negative pressure in both the liquid holding cup 10 and the first cup body 2, so that the liquid in the brewing cup is added to the liquid holding cup 10. Control the opening and closing structure to close so that the liquid in the liquid holding cup 10 is discharged from the first liquid outlet 101 through the siphon device, or control the opening and closing structure to open so that the liquid is discharged from the second liquid outlet 102.

[0181] In the above process, the siphon device draws air from both the liquid-holding cup 10 and the first cup body 2, creating negative pressure within both. This facilitates rapid liquid flow within the liquid-holding cup 10, reducing residual liquid and minimizing its impact on the liquid exiting the second outlet 102. Furthermore, the rapid flow of liquid towards the siphon device reduces pressure on the second outlet 102, improving the stability of its opening and closing structure. The negative pressure within the liquid-holding cup also facilitates the entry of liquid from the brewing cup into the liquid-holding cup.

[0182] Further steps include:

[0183] S101. Control the amount of the first liquid added to the liquid container 10 so that the amount of the first liquid is less than the threshold so that the first liquid in the liquid container 10 cannot be discharged from the siphon channel.

[0184] S102. Control the first liquid to stay in the liquid container 10 for a preset time;

[0185] S103, control the opening and closing structure to open so that the first portion of liquid is discharged from the second outlet 102.

[0186] In the above process, the brewing time can be controlled by allowing the liquid to remain in the liquid container 10 for a preset time. The first portion of liquid remaining in the liquid container 10 can be heated or cooled to obtain a beverage at a suitable temperature.

[0187] Furthermore, it also includes the following steps:

[0188] S101': Control the opening and closing structure to open, and control the first portion of liquid to be added to the liquid container 10;

[0189] S103' Control the first portion of liquid to be discharged from the second outlet 102.

[0190] During the above process, the opening and closing structure is opened, and the first liquid can be discharged directly from the second liquid outlet 102.

[0191] Furthermore, it also includes the following steps:

[0192] S106. Control the amount of the second liquid added to the liquid container 10, so that the amount of the second liquid is greater than the threshold, so that the second liquid in the liquid container 10 enters along the inlet of the siphon channel, flows along the siphon channel, passes through the highest point of the siphon channel, and is discharged from the first outlet 101.

[0193] During the above process, the second portion of liquid can be automatically discharged from the first outlet.

[0194] Further steps include:

[0195] S104. Control the amount of the first liquid added to the liquid container 10 so that the amount of the first liquid is greater than the threshold, so that the first liquid in the liquid container 10 enters along the inlet of the siphon channel, flows along the siphon channel, passes through the highest point of the siphon channel, and is discharged from the first outlet 101.

[0196] S105. Control the amount of the second liquid added to the liquid container 10 to make the amount of the second liquid less than the threshold so that the second liquid in the liquid container 10 cannot be discharged from the siphon channel; after the second liquid stays in the liquid container 10 for a preset time, control the opening and closing structure to open so that the second liquid is discharged from the second outlet 102.

[0197] By controlling the amount of liquid added to the liquid container 10, the liquid can be discharged from the first liquid outlet 101 or the second liquid outlet 102, thereby achieving the technical effect of obtaining different amounts of liquid from the two liquid outlets.

[0198] Furthermore, it also includes the following steps:

[0199] S104. Control the amount of the first liquid added to the liquid container 10 so that the amount of the first liquid is greater than the threshold, so that the first liquid in the liquid container 10 enters along the inlet of the siphon channel, flows along the siphon channel, passes through the highest point of the siphon channel, and is discharged from the first outlet 101.

[0200] S105. Control the opening and closing structure to open, control the second liquid to be added into the liquid cup 10, so that the second liquid is discharged from the second liquid outlet 102.

[0201] In the above implementation process, by controlling the amount of the first liquid added to the liquid container 10, the liquid can be discharged from the first liquid outlet 101; by controlling the opening and closing structure to open, the second liquid can be discharged from the second liquid outlet 102, thus achieving the technical effect of two liquid discharges from two liquid outlets respectively.

[0202] Furthermore, the temperature of the first liquid is lower than the temperature of the second liquid.

[0203] In the above process, a low-temperature-high-temperature soaking is implemented. At this time, the substance to be brewed can be soaked twice at different temperatures and automatically drained to obtain beverages with different extract concentrations, different tastes, or different extracts.

[0204] Furthermore, if the substance to be brewed is coffee, the caffeine concentration of the beverage obtained after brewing the substance with the first batch of liquid is greater than that of the beverage obtained after brewing the substance with the second batch of liquid.

[0205] In the above-described process, the first brewing liquid is discharged as waste liquid, and only the liquid from the second brewing is retained for drinking, which can improve the taste of the beverage. For example, if the beverage to be brewed is coffee, a low-caffeine beverage can be obtained.
