[0025] In the aforementioned water dispenser, the housing has a lower shell and an upper cover.

At least one fluid-carrying external pipe is installed in the second cavity and is connected to the second cavity. The horizontal height of the external pipe is higher than that of the tube inside the shell. When external fluid (water source) is simultaneously connected to the tube and the external pipe, the fluid flows from the tube into the first cavity due to the liquid level difference. Alternatively, if the tube is blocked, the fluid can enter the external pipe and flow out through the second through hole.

[0043] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example 1:

[0044] like Figures 1 to 5 As shown, a water tank includes: a shell 1, a first cavity 100 and a second cavity 101 formed inside the shell 1, a cavity pipe 104 disposed in the first cavity 100, and an outer pipe port 105 disposed in the second cavity 101.

[0045] Specifically, a first through hole 102 is provided on the first cavity 100, and a second through hole 103 is provided on the second cavity 101. The first cavity 100 and the second cavity 101 are connected. The first through hole 102 and the second through hole 103 can be detachably sealed using plugs or other items, so that water (fluid) is stored in the first cavity 100 and the second cavity. When the water stored in the second cavity 101 reaches a preset liquid level, the water in the second cavity 101 overflows and flows into the first cavity 100. A water inlet tube 104 is provided in the first cavity 100 and is connected to the first cavity 100. At least one water inlet port 105 is provided in the second cavity 101. The outer pipe inlet 105 is connected to the second cavity 101. The horizontal height of the outer pipe inlet 105 is higher than that of the cavity pipe 104 inside the shell 1. When an external water source is connected to both the cavity pipe 104 and the outer pipe inlet 105 at the same time, due to the liquid level difference, the water source flows from the cavity pipe 104 into the first cavity 100, but the water source cannot flow from the outer pipe inlet 105 into the second cavity 101. When the cavity pipe 104 is blocked, the water source can enter the outer pipe and flow out from the second through hole 103. When the cavity pipe 104 and the second through hole 103 are blocked, the water source can enter the outer pipe inlet 105 and be stored in the second cavity 101. When the water source in the second cavity 101 is full, the water source will overflow and flow from the second cavity 101 into the first cavity 100, realizing multiple water inlet and outlet methods.

[0046] Specifically, such as Figures 1 to 3 As shown, the housing 1 has a first bottom surface 106 and a second bottom surface 107. The first bottom surface 106 and the second bottom surface 107 are at different heights on the housing 1 and have a height difference. A fixed partition 108 is provided on the second bottom surface 107. The fixed partition 108 separates the first bottom surface 106 and the second bottom surface 107 to form a first cavity 100 and a second cavity 101.

[0047] The height of the first bottom surface 106 in the housing 1 is lower than the height of the second bottom surface 107. A fixed partition 108 is provided on the second bottom surface 107 at a position adjacent to the first bottom surface 106 and the second bottom surface 107, thereby clearly separating the first bottom surface 106 and the second bottom surface 107 into the first cavity 100 and the second cavity 101 mentioned above, so that water overflowing from the second cavity 101 can flow into the first cavity 100.

[0048] Furthermore, such as Figure 2 and Figure 3As shown, the fixed partition 108 has a first part 109 and a second part 110. The first part 109 is arranged along the width direction of the housing 1 and along the length direction of the housing 1. The first part 109 and the second part 110 are perpendicular to each other, and the cavity tube 104 is connected to the first part 109. The second part 110 has a flow channel 111 formed on the second bottom surface 107. The second cavity 101 is connected to the first cavity 100 through the flow channel 111.

[0049] The first part 109 and the second part 110 are perpendicular to each other. The entire fixed partition 108 has an "L" shaped structure, so that in addition to forming the first cavity 100, a flow channel 111 is also formed on the second bottom plate. Water overflowing from the second cavity 101 flows back into the first cavity 100 through the flow channel 111. The flow channel 111 can play a transition role to prevent the water pressure sent into the second cavity 101 from being too high, causing the water in the second cavity 101 to splash and rush into the first cavity 100. The flow channel 111 is a strip-shaped water tank, which has the effect of slowing down the water flow.

[0050] It is worth mentioning that the shape of the fixed partition 108 can be adapted to the shape of the housing 1, and the partition can be used to divide the second bottom plate to form the second cavity 101 and the flow channel 111.

[0051] Furthermore, such as Figures 2 to 5 As shown, the second part 110 has a first notch 112 that connects the flow channel 111 with the second cavity 101, and the top of the cavity tube 104 has a second notch 113. The first notch 112 has a first end face 114, the second notch 113 has a second end face 115, and the outer pipe port 105 has a third end face 116. The first end face 114 and the second end face 115 are on the same horizontal plane, and the plane height of the third end face 116 in the shell 1 is higher than the horizontal height of the second end face 115.

[0052] The first end face 114 and the second end face 115 are on the same horizontal plane, while the outer pipe port 105 has a third end face 116. The height of the third end face 116 is higher than that of the second end face 115. Since the height of the outer pipe port 105 is higher than that of the cavity pipe 104, after the external water source conveying equipment is connected to the cavity pipe 104 and the outer pipe port 105 respectively, water will flow out from the cavity pipe 104 with the lower height.

[0053] Specifically, such as Figure 2 and Figure 3As shown, the cavity tube 104 has a first forming part 117 and a second forming part 118. The first forming part 117 has a third cavity 119. A third through hole 120 that can be sealed is provided on the first forming part 117. The third through hole 120 can communicate with the third cavity 119. The second forming part 118 is connected to the fixed partition 108 and the adjacent part of the first bottom surface 106 and the second bottom surface 107. The second forming part 118 has a flow groove 121 that communicates with the third cavity 119 and the first cavity 100.

[0054] The cavity tube 104 is divided into two parts: a first forming part 117 and a second forming part 118. The third through hole 120 can be detachably sealed by a plug or other items. The second notch 113 is formed at the connection position on one side of the first forming part 117 and the second forming part 118.

[0055] Furthermore, such as Figure 2 and Figure 3 As shown, a first baffle 122 is provided on the end face of the second part 110 away from the flow channel 111. The first baffle 122 is located between the outer pipe port 105 and the first notch 112.

[0056] The first partition 122 is inclined toward the first notch 112 and forms an angle with the second part 110. When the external heating component is connected to the external pipe port 105, the heating component 2 heats the water source, ensuring that the boiling water source is blocked by the first partition 122 and will not splash directly onto the first notch 112, and will flow out from the first notch 112 into the first cavity 100. The first partition 122 plays a protective role.

[0057] Furthermore, such as Figure 2 and Figure 3 As shown, a second partition 129 is provided on the first cavity 100. The second partition 129 is located on the side of the cavity tube 104 and close to the flow channel 111.

[0058] When water in the second cavity 101 overflows and flows from the flow channel 111 into the first cavity 100, the water will splash when it enters the first cavity 100 due to the height difference between the first bottom surface 106 and the second bottom surface 107. The second partition 129 can prevent the water from splashing everywhere.

[0059] Specifically, such as Figure 2 As shown, the housing 1 is provided with an assembly part for mounting a water temperature sensor 123, which can detect the temperature of the liquid stored in the first cavity 100.

[0060] An installation hole is provided on the assembly part, through which the water temperature sensor 123 can be installed in the first cavity 100 to detect whether the water temperature in the first cavity 100 has reached the preset water temperature.

[0061] Specifically, such as Figures 1 to 3 As shown, the housing 1 has a lower shell 128 and an upper cover 127. The lower shell 128 has a threaded hole 124 and a buckle 125 around its periphery. The upper cover 127 has a connecting hole and a bayonet around its periphery. When the upper cover 127 and the lower shell 128 are closed, the buckle 125 is engaged in the bayonet. The connecting hole communicates with the threaded hole 124 and is connected to the threaded hole 124 by bolts.

[0062] The lower shell 128 has a threaded hole 124 and a snap fastener 125 around its periphery. The upper cover 127 has a connecting hole that matches the threaded hole 124 and a snap fastener that matches the snap fastener around its periphery. After the upper cover 127 and the lower shell 128 are fitted together, the threaded hole 124 and the connecting hole are connected and connected by bolts. The snap fastener 125 is inserted into the snap fastener, so that the upper cover 127 and the lower shell 128 can be detachably connected together. It is worth mentioning that the threaded hole 124 and the snap fastener 125 can also be provided on the upper cover 127, and the connecting hole and snap fastener can also be adapted to be provided on the lower shell.

[0063] Furthermore, the upper cover 127 is provided with a liquid inlet 126, which is connected to the first cavity 100.

[0064] The upper cover 127, together with the lower shell 128, serves as a protective seal to prevent external debris from entering the first cavity 100 and the second cavity 101. The liquid inlet 126 can be connected to an external water source, so that water flows into the first cavity 100 through the liquid inlet 126. Example 2:

[0065] like Figures 1 to 11 As shown, the present invention also provides a water dispenser, including the water tank of Embodiment 1, which further includes: a housing 1, a heating component 2, an adjustment component 3, and a drive unit 4.

[0066] Specifically, the housing 1 has a first cavity 100 and a second cavity 101 inside. The first cavity 100 has a first through hole 102 that can be sealed, and the second cavity 101 has a second through hole 103 that can be sealed. The second cavity 101 and the first cavity 100 are connected. A water inlet pipe 104 is provided in the first cavity 100 and is connected to the first cavity 100. At least one water inlet port 105 is provided in the second cavity 101 and is connected to the second cavity 101. A heating component 2 is connected to the second cavity 101 and can heat the water supplied from the outside and send it into the second cavity 101. An adjusting component 3 is provided on the housing 1 and has a valve body 300 that is rotatably mounted on the pipe 104. Figure 9 The valve body 300 has a right-angled trapezoidal slot 301. When the valve body 300 rotates relative to the cavity tube 104, the communication area between the slot 301 and the first cavity 100 can be controlled. The drive unit 4 is disposed on the housing 1 and is connected to the first through hole 102, the heating component 2, and the adjusting component 3. The drive unit 4 can send water from the first cavity 100 into the heating component 2 and the adjusting component 3. When the drive unit 4 sends water from the first cavity 100 into the heating component 2 and the adjusting component 3 and the second through hole 103 is opened, the heating component 2 sends the heated and boiled water into the second cavity 101 and... Water is fed out from the second through hole 103. When the drive unit 4 sends the water source in the first cavity 100 into the heating component 2 and the regulating component 3 and the second through hole 103 is blocked, the heating component 2 sends the heated and boiled water source into the second cavity 101. When the water source reaches the preset liquid level height, the water source in the second cavity 101 overflows and flows into the first cavity 100, causing the water temperature in the first cavity 100 to rise. According to the valve body 300 rotating relative to the cavity tube 104, the communication area between the slot 301 and the first cavity 100 can be controlled, thereby controlling the temperature of the water source heated by the heating component 2 and sent to the second cavity 101.

[0067] Specifically, such as Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the horizontal height of the outer pipe port 105 is higher than the horizontal height of the cavity pipe 104 inside the housing 1.

[0068] The height of the outer pipe port 105 is higher than the height of the cavity 104. The drive unit 4 sends the water source in the first cavity 100 into the heating component 2 and the regulating component 3. The water will flow out from the cavity 104, while the water source in the outer pipe port 105 is heated by the heating component 2 until the water source boils. After boiling, the water flows out from the second cavity 101 into the second through hole 103 or the first cavity 100.

[0069] Furthermore, such as Figure 2 and Figure 3 The housing 1 has a first bottom surface 106 and a second bottom surface 107. The first bottom surface 106 and the second bottom surface 107 are at different heights on the housing 1. A fixed partition 108 is provided on the second bottom surface 107. The fixed partition 108 separates the first bottom surface 106 and the second bottom surface 107 to form a first cavity 100 and a second cavity 101.

[0070] The height of the first bottom surface 106 in the shell 1 is lower than the height of the second bottom surface 107. A fixed partition 108 is provided on the second bottom surface 107 at a position adjacent to the first bottom surface 106 and the second bottom surface 107, thereby clearly separating the first bottom surface 106 and the second bottom surface 107 into the first cavity 100 and the second cavity 101 mentioned above. This allows the heated water overflowing from the second cavity 101 to flow into the first cavity 100 and mix with the room temperature water in the first cavity 100, thereby raising the temperature of the water in the first cavity 100.

[0071] Furthermore, such as Figure 2 , Figure 7 and Figure 8 As shown, the fixed partition 108 has a first part 109 and a second part 110. The first part 109 is arranged along the width direction of the housing 1 and along the length direction of the housing 1. The first part 109 and the second part 110 are perpendicular to each other, and the cavity tube 104 is connected to the first part 109. The second part 110 has a flow channel 111 formed on the second bottom surface 107. The second cavity 101 is connected to the first cavity 100 through the flow channel 111.

[0072] The first part 109 and the second part 110 are perpendicular to each other. The entire fixed partition 108 has an "L" shaped structure, so that in addition to forming the first cavity 100, a flow channel 111 is also formed on the second bottom plate. Water overflowing from the second cavity 101 flows back into the first cavity 100 through the flow channel 111. The flow channel 111 can play a transition role, preventing the boiling water sent into the second cavity 101 from directly rushing into the first cavity 100. The flow channel 111 is a strip-shaped water tank, which has a slowing effect.

[0073] Furthermore, such as Figure 2 , Figure 7 and Figure 8As shown, the second part 110 has a first notch 112 that connects the flow channel 111 with the second cavity 101, and the top of the cavity tube 104 has a second notch 113. The first notch 112 has a first end face 114, the second notch 113 has a second end face 115, and the outer pipe port 105 has a third end face 116. The first end face 114 and the second end face 115 are on the same horizontal plane, and the plane height of the third end face 116 in the shell 1 is higher than the horizontal height of the second end face 115.

[0074] The first end face 114 and the second end face 115 are on the same horizontal plane, while the outer pipe port 105 has a third end face 116. The height of the third end face 116 is higher than that of the second end face 115. Since the height of the outer pipe port 105 is higher than that of the cavity 104, the drive unit 4 is connected to the heating component 2 and the adjustment component 3. The drive unit pumps the water in the first cavity 100 to the cavity 104 and the outer pipe port 105. The water will flow out from the cavity 104, which is at a lower height, while the water in the outer pipe port 105, which is at a higher position, will be heated by the heating component 2. When the water boils, the boiled water will flow into the second cavity 101 through the outer pipe port 105.

[0075] Specifically, such as Figure 2 , Figure 7 and Figure 8 As shown, the cavity tube 104 has a first forming part 117 and a second forming part 118. The first forming part 117 has a third cavity 119. The valve body 300 is rotatably mounted on the first forming part 117. The first forming part 117 has a sealable third through hole 120, which can communicate with the third cavity 119. The second forming part 118 is connected to the fixed partition 108 and the connection between the first bottom surface 106 and the second bottom surface 107. The second forming part 118 has a flow groove 121. The third cavity 119 is connected to the first cavity 100 through the flow groove 121. When the valve body 300 rotates relative to the cavity tube 104, it can control the communication area between the slot 301 and the flow groove 121.

[0076] The cavity tube 104 is divided into two parts: the first forming part 117 and the second forming part 118. The third through hole 120 is connected to the adjustment component 3. The second notch 113 is formed on one side of the connection position of the first forming part 117 and the second forming part 118. When the valve body 300 rotates relative to the cavity tube 104, it can control the communication area between the slot 301 and the flow channel 121, thereby ensuring the water source height in the heating component 2 and controlling the temperature of the water source entering the second cavity 101 through the outer pipe port 105.

[0077] Furthermore, such as Figure 2 , Figure 7 and Figure 8As shown, a first baffle 122 is provided on the end face of the second part 110 away from the flow channel 111. The first baffle 122 is located between the outer pipe port 105 and the first notch 112.

[0078] The first partition 122 is inclined toward the first notch 112. When the external water source is connected to the external pipe port 105, the water heated by the heating component 2 will boil, ensuring that the water boiling in the external pipe port 105 to the second cavity 101 will not splash to the first notch 112. The first partition 122 plays a protective role, ensuring that the water source in the first cavity 100 is stable and unaffected.

[0079] Furthermore, such as Figure 2 , Figure 7 and Figure 8 As shown, a second partition 129 is provided on the first cavity 100. The second partition 129 is located on the side of the cavity tube 104 and close to the flow channel 111.

[0080] When water stored in the second cavity 101 overflows and flows from the flow channel 111 into the first cavity 100, the second partition 129, due to the height difference between the first bottom surface 106 and the second bottom surface 107, can prevent water from flowing from the flow channel 111 into the first cavity 100 and splashing everywhere.

[0081] Specifically, the housing 1 is provided with an assembly part for mounting a water temperature sensor 123, which can detect the temperature of the liquid stored in the first cavity 100.

[0082] An installation hole is provided on the assembly part, through which the water temperature sensor 123 can be installed in the first cavity 100, and the hole is sealed with a sealing material, so that the water temperature sensor 123 can detect whether the water temperature in the first cavity 100 has reached the preset water temperature.

[0083] Specifically, such as Figure 1 and Figure 6 As shown, the housing 1 has a lower shell 128 and an upper cover 127. The lower shell 128 has a threaded hole 124 and a buckle 125 around its periphery. The upper cover 127 has a connecting hole and a bayonet around its periphery. When the upper cover 127 and the lower shell 128 are closed, the buckle 125 is engaged in the bayonet. The connecting hole communicates with the threaded hole 124 and is connected to the threaded hole 124 by bolts.

[0084] The lower shell 128 has a threaded hole 124 and a snap fastener 125 around its periphery. The upper cover 127 has a connecting hole that matches the threaded hole 124 and a snap fastener that matches the snap fastener around its periphery. After the upper cover 127 and the lower shell 128 are fitted together, the threaded hole 124 and the connecting hole are connected and connected by bolts. The snap fastener 125 is inserted into the snap fastener, so that the upper cover 127 and the lower shell 128 are detachably connected together.

[0085] Furthermore, such as Figure 6 As shown, the upper cover 127 is provided with a liquid inlet 126, which is connected to the first cavity 100.

[0086] The liquid inlet 126 can be connected to an external water source, so that the water source flows into the first cavity 100 through the liquid inlet 126, and the water in the first cavity 100 is sent to the heating component 2 or the regulating component 3 through the drive unit 4.

[0087] Specifically, such as Figure 10 and Figure 11 As shown, the heating component 2 includes a housing 200, inside which is disposed at least one heating tube 201. One end of the heating tube 201 is provided with a water inlet 202, and the other end of the heating tube 201 is provided with a water outlet 203; at least two electrodes 204 are sleeved on the heating tube 201, and the electrodes 204 are connected to an externally disposed switching device.

[0088] Two electrodes 204 are respectively sleeved on both ends of the heating tube 201. The lower end of the heating tube 201 is provided with a water inlet 202, which is connected to the drive unit 4. The water outlet 203 of the heating tube 201 is connected to the liquid inlet 126. When the drive unit 4 sends the water source in the first cavity 100 to the heating tube 201, the electrodes 204 form a heating section. The external switch device turns on the switch to heat the water source. The heated and boiling water flows out from the liquid inlet 126 into the second cavity 101.

[0089] It is worth mentioning that three electrodes 204 can be evenly mounted on the heating tube 201, two at both ends of the heating tube 201 and one in the lower middle part of the heating tube 201. Thus, the lower electrode 204 and the middle electrode 204 form one heating section, while the middle electrode 204 and the upper electrode 204 form two heating sections. This achieves uniform heating of the heating tube 201. Compared with heating tubes 201 of the same specification, at the same heating rate, the heating power required for the heating tube 201 is reduced, the damage to the heating tube 201 is reduced, and the service life of the heating tube 201 can be extended.

[0090] Furthermore, such as Figure 10 and Figure 11As shown, when at least two heating tubes 201 are provided inside the housing 200, the heating assembly 2 also includes: a water inlet sleeve 205, which is sleeved on the water inlet end 202 of the two heating tubes 201, and has a water inlet hole 206 connected to an external water source device.

[0091] Multiple heating tubes 201 can heat the water source simultaneously, accelerating the boiling of the water source into the second cavity 101, so that enough heated water source can be sent out of the second through hole 103 to the second through hole 103 or the first cavity 100.

[0092] Furthermore, such as Figure 11 As shown, the diameter of the inlet sleeve is equal to or smaller than the diameter of the outlet sleeve.

[0093] When two heating tubes 201 are installed inside the outer casing 200, the diameter of the inlet sleeve hole is equal to or smaller than the diameter of the outlet sleeve hole, thereby dividing a certain amount of water source into two paths. Due to the limited amount of water entering, the heating tubes 201 can quickly heat the water source.

[0094] Furthermore, such as Figure 10 As shown, a thermostat 207 is provided on the outer casing 200, and the thermostat 207 is connected to the heating tube 201.

[0095] The thermostat 207 is always pressed against the outside of the heating element 201 to achieve rapid power cut-off, thereby providing protection and preventing the heating element 201 and the housing 1 from being burned.

[0096] Furthermore, such as Figure 10 As shown, an electric wire 208 is connected to the electrode 204. The electric wire 208 extends out of the outer casing 200 and is covered with a fiberglass rope.

[0097] The wire 208 is sheathed with a fiberglass rope, which has a high temperature resistance effect. The electrode 204 is connected to an external power supply device through the wire 208.

[0098] Specifically, such as Figure 6 As shown, a liquid level sensor 127 is provided on the housing 1, which can detect the amount of water stored in the first cavity 100.

[0099] A mounting hole is provided on the upper cover 127 of the housing 1. The liquid level sensor 127 can be inserted into the first cavity 100 through the mounting hole. The liquid level sensor 127 has a minimum liquid level and a maximum liquid level. When the water level in the first cavity 100 is lower than the minimum liquid level, the external water source equipment connected to the liquid inlet 126 starts to supply water. When the water level in the first cavity 100 is higher than the maximum liquid level, the external water source equipment connected to the liquid inlet 126 stops supplying water, thereby ensuring that the water level in the second cavity 101 is not too high or too low.

[0100] Specifically, such as Figure 6 As shown, the regulating component 3 has a first solenoid valve 302, which is mounted on the housing 1. The inlet end of the first solenoid valve 302 is connected to the drive unit 4, and the outlet end of the first solenoid valve 302 is connected to the third through hole 120.

[0101] Users can control the water source supplied into the third through hole 120, i.e., the cavity tube 104, through the first solenoid valve 302, so that water flows only from the heating tube 201 to the outlet of the second cavity 101, or the water in the second cavity 101 flows into the first cavity 100 to heat the water in the first cavity 100.

[0102] Specifically, such as Figure 6 As shown, the drive unit 4 is configured as a water pump 400. The water pump 400 is mounted on the housing 1 and has an input end 401 and an output end 402. The input end 401 is connected to the first through hole 102, and the output end 402 is connected to the heating component 2 and the adjustment component 3.

[0103] The input end 401 of the water pump 400 is connected to the first through hole 102, and the output end 402 of the water pump 400 is connected to the heating component 2 and the regulating component 3 through the diversion water pipe (not shown in the figure). Thus, after the water pump 400 is started, it delivers the water in the first cavity 100 to the heating pipe 201 or to the first solenoid valve 302 to enter the cavity pipe 104.

[0104] Specifically, such as Figures 6 to 8 As shown, the adjustment component 3 has a stepper motor 303, which is mounted on the upper cover 127. The drive end of the stepper motor 303 passes through the upper cover 127 and is connected to the valve body 300.

[0105] When the stepper motor 303 drives the valve body 300 to rotate relative to the cavity tube 104, it can control the communication area between the slot 301 and the flow channel 121. When the communication area between the slot 301 and the flow channel 121 is small, the water flow rate at the cavity tube 104 is small, while the water flow rate in the heating tube 201 increases. When the communication area between the slot 301 and the flow channel 121 increases, the water flow rate at the cavity tube 104 increases, while the water flow rate in the heating tube 201 decreases, thereby controlling the water level in the heating tube 201 and ensuring the heating tube... The water heated by the heating pipe 201 is at different temperatures. It is worth mentioning that when the communication area between the slot 301 and the flow channel 121 is at its maximum, the height of the third end face 116 of the outer pipe port 105 is higher than the horizontal height of the second end face 115 of the cavity pipe 104. There is a preset height difference between the third end face 116 and the second end face 115. Therefore, when the water in the cavity pipe 104 flows out into the first cavity 100, the water in the outer pipe port 105 needs to be heated and boiled by the heating pipe 201 before it can enter the second cavity 101.

[0106] Furthermore, a second solenoid valve 209 is installed on the housing 1. The inlet end of the second solenoid valve 209 is connected to the second through hole 103, and the outlet end of the second solenoid valve 209 is connected to an externally installed conveying device.

[0107] The second solenoid valve 209 controls the opening or closing of the second through hole 103, thereby allowing the hot water in the second container to flow into the second solenoid valve 209 and into the external conveying device, or allowing the hot water in the second container to overflow and enter the first cavity 100 through the flow channel 111 after it is full.

[0108] The working principle of a water dispenser: (I) Boiling Water Mode Both the first solenoid valve 302 and the second solenoid valve 209 are open. The water pump 400 is connected to the heating component 2 and the first solenoid valve 302 respectively through the diversion water pipe, and sends the room temperature water in the first cavity 100 to the heating component 2 and the first solenoid valve 302. Since there is a second notch 113 on the cavity tube 104, and the height of the second end face 115 on the second notch 113 is lower than the height of the third end face 116 of the outer pipe port 105, the room temperature water in the cavity tube 104 will flow back into the first cavity 100 along the second notch 113, while the water in the heating tube 201 is heated. The water in the outer pipe port 105 is kept at the same height as the second notch 113. After the water in the heating tube 201 boils, it flows out from the outer pipe port 105 into the second cavity 101, so the hot water in the second cavity 101 is sent out from the second solenoid valve 209.

[0109] (ii) Preheating mode The first solenoid valve 302 is open, and the second solenoid valve 209 is closed. The water pump 400 is connected to the heating assembly 2 and the first solenoid valve 302 respectively through the diversion pipe, and sends the room temperature water in the first cavity 100 to the heating assembly 2 and the first solenoid valve 302. Because there is a second notch 113 on the cavity pipe 104, and the height of the second end face 115 on the second notch 113 is lower than the height of the third end face 116 of the outer pipe port 105, the room temperature water in the cavity pipe 104 will flow back along the second notch 113. The water flows into the first cavity 100, while the water in the heating tube 201 is heated. The water in the outer pipe port 105 is kept at the same height as the second notch 113. After the water in the heating tube 201 boils, it flows out from the outer pipe port 105 and into the second cavity 101. When the water in the second cavity 101 is full, it overflows from the first notch 112 and flows into the first cavity 100 through the flow channel 111, mixing with the room temperature water in the first cavity 100, thereby raising the temperature of the water in the first cavity 100.

[0110] Assuming that hot water of about 50 degrees Celsius is required at the second solenoid valve 209, when the water in the first chamber 100 reaches the preset value, the first solenoid valve 302 closes, the second solenoid valve 209 opens, and the heating tube 201 stops heating. The water pump 400 sends the water in the first chamber 100 into the second chamber 101 through the heating tube 201 and out through the second solenoid valve 209.

[0111] (III) Temperature Adjustment Mode In preheating mode, the stepper motor 303 is driven to adjust the rotation of the valve body 300 relative to the cavity tube 104, controlling the communication area between the slot 301 and the flow channel 121. When the communication area between the slot 301 and the flow channel 121 is small, the water flow rate at the cavity tube 104 is small, while the water flow rate in the heating tube 201 increases. The water temperature fed into the second cavity 101 may be around 70 degrees Celsius. When the communication area between the slot 301 and the flow channel 121 increases, the water flow rate at the cavity tube 104 increases, while the water flow rate in the heating tube 201 decreases. The boiling water flowing into the second cavity 101 may reach a temperature that rises from 70 degrees Celsius to 90 degrees Celsius, thereby ensuring that the water heated by the heating tube 201 is at different temperatures.
