[0037] Reference Figure 1-Figure 4A water boiler 100 includes an adapter assembly 11, a water pump 12, and a heating pipe 13. The adapter assembly 11 has a water storage chamber, the water inlet of the water pump 12 is connected to the water storage chamber of the adapter assembly 11, and the water outlet of the water pump 12 is connected to the inner cavity of the heating pipe 13; the water boiler 100 has a water outlet seat 14 and a reflux channel 101. The water outlet seat 14 is located above the heating pipe 13, and the inner cavity of the heating pipe 13 is connected to the inner cavity of the water outlet seat 14. The water outlet seat 14 has a water outlet 141. One end of the reflux channel 101 is connected to the inner cavity of the water outlet seat 14, and the other end of the reflux channel 101 is connected to the adapter assembly 11;

[0038] The communication hole between the adapter assembly 11 and the return channel 101 is defined as a first hole 106 , and the communication hole between the adapter assembly 11 and the water pump 12 is defined as a second hole 107 . The height of the first hole 106 is greater than that of the second hole 107 .

[0039] The water boiler 100 pumps the water in the adapter seat assembly 11 to the heating tube 13 through the water pump 12. When the heating tube 13 is powered on and heated, the water in the heating tube 13 is heated into boiling water and flows out from the water outlet seat 14 above the heating tube 13 and flows out from the water outlet 141. The water vapor and / or air in the inner cavity of the water outlet seat 14 enters the adapter seat assembly 11 through the reflux channel 101. Since the height of the first hole 106 through which the reflux channel 101 enters the adapter seat assembly 11 is greater than the second hole 107 connecting the adapter seat assembly 11 and the water pump 12, the reflux channel has the functions of both a reflux water channel and an air supply channel.

[0040] The adapter assembly 11 has a water source inlet 105. The height of the first hole 106 is less than that of the water source inlet 105. The reflux channel 101 can discharge gas more smoothly to the water source inlet 105, facilitating the gas to enter the interior of an external water bottle or bucket connected to the water source inlet 105. This allows the cold water at the water source inlet 105 to be continuously pumped away by the water pump 12, achieving smooth heating of the cold water and continuous water output (when there is sufficient water). The above-mentioned water boiler 100 can be operated by supplying power to the water pump 12 and the heating tube 13. The water pump 12 can operate independently without the aid of an external circuit board, has a simple structure, and has a low overall structural cost.

[0041] Herein, "water source inlet 105" refers to the position where the external water source enters the adapter assembly 11 when the adapter assembly 11 is connected to an external water source such as a bucket or a water bottle. "One end of the water pump 12 is connected to the adapter assembly 11" includes direct communication between one end of the water pump 12 and the adapter assembly 11, or communication through a connecting pipe or through other components. Similarly, "the other end of the water pump 12 is connected to the heating pipe 13" also includes direct communication between the two, or communication through a connecting pipe or through other components. Similar terms are understood similarly below.

[0042] The heating tube 13 may be a heating component having a flow channel therein. A heating resistor is disposed on the outer wall of the heating tube 13 to heat the water inside the heating tube 13. There may be one or more heating tubes 13, and the two or more heating tubes 13 may be connected in series or in parallel. The heating resistor on the outer wall of the heating tube 13 may be an electric heating film, a heating wire, or an electric heating sheet, and the electric heating film may include thick film or thin film.

[0043] The water outlet seat 14 has a water outlet chamber 142 and a reflux chamber 1451. The inner cavity of the water outlet chamber 142 is connected to the upper port of the heating tube 13, the inner cavity of the water outlet chamber 142 is connected to the water outlet 141, and the reflux chamber 1451 is connected to the reflux channel 101. The water outlet seat 14 has a first baffle 143. The water outlet chamber 142 is located on one side of the first baffle 143, and the reflux chamber 1451 is located on the other side of the first baffle 143. The first baffle 143 has a notch 1431, which is located at the top of the first baffle 143. The notch 1431 connects the reflux chamber 1451 and the water outlet chamber 142.

[0044] As an embodiment, the notch 1431 may be in the form of a hole, which is located near the top of the first baffle 143 , and the hole connects the reflux chamber 1451 and the water outlet chamber 142 .

[0045] As another embodiment, the notch 1431 may be in the form of a groove, which is located on the top of the first baffle 143 , and the groove connects the reflux chamber 1451 and the water outlet chamber 142 .

[0046] The first baffle 143 is provided with a groove or hole structure, so that the water vapor and / or air in the water chamber 142 can enter the reflux chamber 1451 through the groove or hole structure, on the one hand, realizing the recovery of the heat of the water vapor, and on the other hand, the water vapor entering the reflux channel 101 can enable the water in the adapter assembly 11 to be smoothly pumped away by the water pump 12, thereby realizing continuous heating of the water.

[0047] Herein, the buffer chamber 145 and the water outlet chamber 142 are not completely enclosed structures, and a portion thereof needs to be enclosed by the first baffle 143 . This distinction is made herein to more clearly illustrate the structures of each portion.

[0048] The water outlet seat 14 has a shell 146 and a cover body 147, and the shell 146 and the cover body 147 are assembled and fixed; the first baffle 143 is integrally formed in the shell 146, and the notch 1431 of the first baffle 143 can form a connecting hole with the shell 146, and the notch 1431 of the first baffle 143 can also form a connecting hole with the cover body 147, which is used for gas communication between the reflux chamber 1451 and the water outlet chamber 142.

[0049] The water outlet seat 14 has a convex wall 144 that protrudes from the bottom of the water outlet seat 14. An air channel 104 is formed between the convex wall 144 and the side walls and top wall of the water outlet seat 14. The air channel 104 is connected to the external environment and is connected to the notch 1431 of the first baffle 143. The air channel 104 allows air from the external environment to enter the water outlet chamber 142. The air in the water outlet chamber 142 then passes through the notch 1431 of the first baffle 143 and enters the return chamber 1451, and then enters the return channel 101.

[0050] The bottom 1461 of the housing is provided with a water outlet 141. The first opening 102 of the air passage 104 is located at the bottom 1461 of the housing. The opening of the air passage 104 at the bottom 1461 of the housing is adjacent to the water outlet 141. The second opening of the air passage 104 is located between the top of the convex wall 144 and the cover 147. The air passage 104 is provided near the water outlet 141, and the openings connecting the water outlet seat 14 to the outside are centrally arranged, making the overall structure of the water boiler 100 more aesthetically pleasing.

[0051] The water outlet 14 has a raised portion 1421 that protrudes from the bottom of the water outlet 14. The raised portion 1421 is lower than the first baffle 143. The interior of the raised portion 1421 communicates with the inner cavity of the heating tube 13. The water outlet 141 is located on one side of the raised portion 1421, and the return chamber 1451 is located on the other side of the raised portion 1421. This creates an opposite direction for the water flow and air flow, resulting in smoother fluid flow and more stable water discharge within the water outlet 14. In terms of the height of the water boiler 100, the second opening is located higher than the raised portion 1421.

[0052] The water outlet seat 14 has a buffer chamber 145 and a balance tank 15. The buffer chamber 145 includes a reflux chamber 1451 and a communication chamber 1456. The balance tank 15 is in communication with the communication chamber 1456. The water pump 12 is in communication with the communication chamber 1456.

[0053] The top of the reflux chamber 1451 is connected to the communication chamber 1456, the top of the water outlet chamber is connected to the reflux chamber 1451, the reflux chamber is connected to one end of the reflux channel, the bottom of the communication chamber 1456 is connected to the top of the balance tank, and the water outlet of the water pump is connected to the inner cavity of the communication chamber. In this way, after the water inlet of the water pump enters the communication chamber, a portion of the water enters the balance tank from the bottom of the communication chamber, and the water overflowing from the communication chamber enters the reflux chamber through the top of the communication chamber and enters the reflux channel. In addition, because the top of the reflux chamber is connected to the top of the water outlet chamber, the air and / or water vapor at the top of the water outlet chamber can enter the reflux chamber from the top and also enter the reflux channel, so that the reflux channel can not only reflux water but also have the function of replenishing air.

[0054] The buffer chamber 145 and the balancing tank 15 are an integrated structure. The buffer chamber 145 is located above the balancing tank 15, which is sealed. The top of the balancing tank 15 is connected to the buffer chamber 145, and the bottom of the balancing tank 15 is connected to the inner cavity of the heating tube 13. The water pump 12 is located below the buffer chamber 145. The bottom of the balancing tank is connected to the bottom of the heating tube via a U-shaped channel. In this article, the U-shaped channel is not limited to a U-shape and includes other U-shaped structures such as right-angled, angled, or corrugated shapes. The U-shaped channel includes a flow channel formed by a single component, such as a U-shaped tube.

[0055] The sealing arrangement of the balance box 15 means that the entire structure of the balance box 15 is sealed relative to the external environment, and the balance box 15 is connected to other components through the provided communication port.

[0056] Water pumped by water pump 12 first enters buffer chamber 145, then enters balance tank 15 and finally enters heating tube 13. Water overflowing from buffer chamber 145 enters return chamber 1451 and returns to adapter assembly 11 through return channel 101. The provision of buffer chamber 145 eliminates the need for high precision in the fluid pumped by water pump 12; the pumped flow rate only needs to be greater than the flow rate entering heating tube 13. Excess water in buffer chamber 145 returns to adapter assembly 11 through return channel 101, thus reducing pump selection requirements and enabling a simple centrifugal pump to achieve the desired function. This results in a simple structure and low cost.

[0057] The setting of the balance box 15 can be used to prevent the heating tube 13 from drying out. A floating mechanism such as a float or a buoy can be provided in the balance box 15 to control the power on and off of the heating tube 13 by controlling the liquid level in the balance box 15.

[0058] The water outlet seat 14 has a second baffle 1457, the reflux chamber 1451 is located on one side of the second baffle 1457, and the communication chamber 1456 is located on the other side of the second baffle 1457; the second baffle 1457 is located in the shell 146, and a certain distance is separated between the top of the second baffle 1457 and the cover body 147.

[0059] In this article, the reflux chamber 1451 and the communication chamber 1456 are not completely closed structures, and a part of them needs to be enclosed by the second baffle 1457. In order to more clearly illustrate the structure of each part, this distinction is made in this article.

[0060] Buffer chamber 145 has a first port 1453, a second port 1453, and a third port 1455. First port 1453 communicates with water pump 12, second port 1453 communicates with balancing tank 15, and third port 1455 communicates with adapter assembly 11. Third port 1455 is located in return chamber 1451, while first port 1453 and first port 1453 are located in communication chamber 1456. The heights of first port 1453 and first port 1453 are lower than the height of second baffle 1457; first port 1453 is located higher than the height of first port 1453. The inner diameter of third port 1455 is larger than the inner diameter of the first hole, facilitating the entry of air and / or water vapor into the return channel.

[0061] Water overflowing from the communication chamber 1456 can pass over the second baffle 1457 and enter the reflux chamber 1451 , and then enter the reflux channel 101 from the third port 1455 .

[0062] In the height direction of the water boiler 100, the height of the protrusion 1421 is 0-10 mm higher than the second baffle 1457. In this way, when the heating tube 13 is heated, the water in the heating tube 13 can boil in the heating tube 13 due to the density difference between cold and hot water and then flow out of the protrusion 1421.

[0063] The water pump 12 is located below the heating tube 13; the channel between the water pump 12 and the adapter assembly 11 is defined as a liquid inlet channel, and the inner diameter or equivalent inner diameter of the liquid inlet channel is smaller than the inner diameter or equivalent diameter of the return channel 101, so that the water entering the return channel 101 from the return chamber 1451 will not fill the return channel 101, so that the return channel 101 can not only return water to the adapter assembly 11, but also return air or water vapor to the adapter assembly 11, which is more conducive to eliminating the vacuum negative pressure formed by the external water source connected to the adapter assembly 11 after the water is discharged, so that the water from the external water source is continuously supplied to the adapter assembly 11.

[0064] The water boiler 100 has a first connecting pipe 16a and a second connecting pipe 16b. The first connecting pipe 16a connects the adapter assembly 11 and the water pump 12. The reflux channel 101 is located in the second connecting pipe 16b. At this time, the inner diameter of the first connecting pipe 16a is smaller than the inner diameter of the second connecting pipe 16b.

[0065] The water boiler 100 is connected to the adapter assembly 11 and the water pump 12, as well as the return water chamber and the adapter assembly 11 through the first connecting pipe 16a and the second connecting pipe 16b. It has a simple structure and low cost.

[0066] As another embodiment, refer to Figure 5The water boiler may include a base portion 17, a portion of which forms the adapter assembly 11, the base portion 17 having a portion for accommodating the water pump 12, and a first communication channel 19a and a second communication channel 19b. The first communication channel 19a connects the water pump 12 and the adapter assembly 11, and the second communication channel 19b is a portion of the return channel 101. In this case, the equivalent inner diameter or inner diameter of the first communication channel 19a is smaller than the equivalent inner diameter or inner diameter of the second communication channel 19b.

[0067] The base 17 of the water boiler 100 is formed with an adapter assembly 11 and a portion for accommodating the water pump 12 , so that the base 17 itself has a first communication channel 19 a and a second communication channel 19 b , and the overall structure is compact.

[0068] It should be noted that the above two embodiments are merely examples, and the communication channel between the water pump 12 and the adapter assembly 11 and the communication channel between the return chamber 1451 and the adapter assembly 11 may also have other embodiments.

[0069] The adapter assembly 11 has a one-way valve 111 , which is used to prevent water from flowing back into the adapter assembly after the water pump is shut down.

[0070] The water boiler 100 includes a connector 18, and the adapter assembly 11 has a mounting portion 112. Part of the connector 18 extends into the adapter assembly 11 and is connected to the adapter assembly 11, or in other words, the connector 18 is connected to the mounting portion 112. The connector 18 is used to install an external water source, such as a water bottle or a bucket. The one-way valve 111 is located below the mounting portion 112, and the connector 18 is located above the one-way valve 111. The connector 18 has a check valve 181. After the connector 18 is installed on the adapter assembly 11, the check valve 181 is in an open state, and the external water source connected to the connector 18 can enter the interior of the adapter assembly 11 from the check valve 181. At this time, the water outlet of the connector 18 is the water source inlet 105, and the height of the water outlet of the connector is greater than the height of the first hole 106.

[0071] Reference Figure 2 、 Figure 6 、 Figure 7 and Figure 8 The water boiler 100 may further include a micro switch 23 and a floating mechanism 21. The floating mechanism 21 is located in the balance box 15. The micro switch 23 is located at the top of the balance box 15. The floating mechanism 21 has an action part 211. The action part 211 is located below the action arm 231 of the micro switch 23. The action part 211 can drive the action arm 231 of the micro switch 23 to move. The micro switch 23 controls the circuit connectivity of the heating tube 13.

[0072] When the water heater 100 is operating, the water pump 12 starts and pumps water from the adapter assembly 11 to the balancing tank 15. The balancing tank 15 contains a float mechanism 21. Because the microswitch 23 is located at the top of the balancing tank 15, and the operating portion 211 of the float mechanism 21 is located below the actuating arm 231 of the microswitch 23, as the water level in the balancing tank 15 gradually rises, the float mechanism 21 rises with the water level. At this time, the operating portion 211 can drive the actuating arm 231 of the microswitch 23 to move, closing the microswitch 23 and connecting the circuit of the heating tube 13. In this way, the float mechanism 21 will remain at a high water level only when there is water in the balancing tank 15. Only then can the float mechanism 21 close the microswitch 23, connecting the circuit of the heating tube 13 and heating the heating tube 13. This ensures that the water heater will not start heating the heating tube until the water level in the heating tube reaches a predetermined level, preventing damage to the machine due to dry-boiling when there is insufficient water in the heating tube during startup. The mechanical structure of the water boiler 100 prevents the heating tube 13 of the water boiler 100 from drying out, thereby improving safety performance.

[0073] The balance box 15 is sealed, and the action part 211 has a first magnet 213. The action arm 231 of the micro switch 23 is provided with a second magnet (not shown). The first magnet 213 and the second magnet (not shown) are arranged opposite each other, and the magnetic poles of the first magnet 213 and the second magnet (not shown) on the opposite sides are the same. When the first magnet 213 of the floating mechanism 21 rises to the top of the balance box 15 or near the top as the water level rises, the first magnet 213 exerts a repulsive force on the second magnet (not shown), causing the action arm 231 with the second magnet (not shown) to be actuated by the repulsive force, thereby closing the circuit controlled by the micro switch 23.

[0074] The floating mechanism 21 has a stop point 212 . When the floating mechanism 21 is located at the stop point 212 , the first magnet 213 pushes the second magnet (not shown) to move, and the micro switch 23 closes the circuit of the heating tube 13 , and the heating tube 13 is heated.

[0075] As another embodiment, the balance box 15 is sealed, the action part 211 has a first magnet 213, and the action arm 231 of the micro switch 23 is provided with a second magnet (not shown). The first magnet 213 and the second magnet (not shown) are arranged opposite to each other, and the magnetic poles of the first magnet 213 and the second magnet (not shown) on opposite sides are opposite. At this time, when the first magnet 213 of the floating mechanism 21 rises to the top of the balance box 15 or near the top as the water level rises, the first magnet 213 has an attraction on the second magnet (not shown), so that the action arm 231 with the second magnet (not shown) is actuated by the attraction, closing the circuit controlled by the micro switch 23.

[0076] The floating mechanism 21 has a stop point 212 . When the floating mechanism 21 is located at the stop point 212 , the first magnet 213 pulls the second magnet (not shown) to move, and the micro switch 23 closes the circuit of the heating tube 13 , and the heating tube 13 is heated.

[0077] By disposing the first magnet 213 and the second magnet (not shown), the balance tank 15 can trigger the opening and closing of the micro switch 23 even when it is sealed, which helps to ensure the hygiene of the drinking water in the balance tank 15.

[0078] As another embodiment, the action portion 211 may also be a structure similar to an action rod. In this case, the action rod may be sealed against the wall of the balance box 15, so that the balance box 15 can be sealed and the sanitation of the water in the balance box 15 can be ensured. The action rod may act on the action arm 231 of the micro switch 23 by pushing force, so that the micro switch 23 closes the circuit of the heating tube 13, and the heating tube 13 can be heated.

[0079] The sealing arrangement of the balance box 15 means that the entire structure of the balance box 15 is sealed relative to the external environment, and the balance box 15 is connected to other components through the provided communication port.

[0080] The height of the balancing box is no less than 3 / 5-4 / 5 of the height of the heating tube. This allows the floating mechanism to have greater buoyancy within the balancing box, facilitating more stable control of the microswitch. The position of the stop point 212 is determined by the floating mechanism 21, and the height of the stop point 212 is higher than the height of the heating resistor provided on the heating tube 13. Thus, when the water in the balancing box 15 reaches the stop point 212, the heating resistor of the heating tube 13 can continue to heat the water, reducing the risk of the heating tube 13 drying out and extending the service life of the heating tube 13. Furthermore, the height of the stop point 212 can be no lower than the height of the heating tube 13.

[0081] The water boiler 100 has a fixing seat 22, which is located on the top of the balance box 15. The fixing seat 22 has a groove 221, and the action arm 231 of the micro switch 23 is located in the groove 221. In the height direction of the water boiler 100, the notch 222 of the groove 221 is larger than the thickness of the action arm 231.

[0082] Reference Figure 3 、 Figure 4A limiting wall 151 protrudes from the top of the balance box 15, and the fixed seat 22 is limited by the limiting wall 151. The first magnet 213 of the floating mechanism 21 is projected into the area surrounded by the limiting wall 151 in the height direction. The fixed seat 22 is limited by the limiting wall 151, which helps to determine the position of the fixed seat 22 on the top of the balance box 15, and is more conducive to ensuring that the second magnet (not shown) of the micro switch 23 and the first magnet 213 of the floating mechanism 21 correspond to each other, which helps the first magnet 213 to accurately act on the second magnet (not shown).

[0083] Reference Figure 9 and Figure 10 , Figure 9 and Figure 10 This is an assembly implementation diagram of the water boiler 100 when in use. Figure 9 and Figure 10 A drinking water device 200 is shown, comprising a water machine 100 and a water bottle 201. The structure of the water machine 100 is as shown in the above embodiment. Figure 8 The top of the middle water outlet seat 14 has been omitted. The connector 18 is connected to the water bottle 201, and the connector 18 is connected to the mounting portion 112 of the adapter assembly 11. The water bottle 201 has a bottom, and the water source inlet 105 is located at the bottom of the connector 18. The water outlet of the connector 18 can be defined as the water source inlet 105. The one-way valve 111 is located below the mounting portion 112, and the connector 18 is located above the one-way valve 111. The connector 18 has a check valve 181. After the connector 18 is installed in the adapter assembly 11, the check valve 181 provided on the connector 18 is in the open state, and the water in the water bottle 201 connected to the connector 18 can enter the interior of the adapter assembly 11 through the check valve 181.

[0084] During operation, the water machine 100 pumps the water in the adapter assembly 11 to the buffer chamber 145 through the water pump 12, and enters from the first port 1453 of the communication chamber 1456. A portion of the water enters the balance tank 15 from the second port 1454, and the water in the balance tank 15 enters the heating pipe 13. When the heating pipe 13 is powered on and heated, the water in the heating pipe 13 is heated to boiling water and flows out from the water outlet seat 14 above the heating pipe 13 and out from the water outlet 141. The water overflowing from the communication chamber 1456 enters the reflux channel 10 from the third port 1455 located in the reflux chamber 1451. 1. The water vapor and / or air in the inner cavity of the water outlet seat 14 enters the reflux channel 101 along with the overflowed water, and then enters the adapter seat assembly 11. Since the height of the first hole of the reflux channel 101 entering the adapter seat assembly 11 is greater than the second hole connecting the adapter seat assembly 11 and the water pump 12, and the height of the first hole is less than the height of the water source inlet 105, the reflux channel 101 can discharge gas toward the water source inlet 105, and the gas enters the water bottle, so that the cold water in the water bottle can be continuously pumped away by the water pump 12, thereby achieving smooth heating of the cold water and continuous water discharge (when there is sufficient water). The above-mentioned water boiler 100 can work when the power supply is supplied to the water pump 12 and the heating tube 13. The water pump 12 can work independently without the help of an external circuit board. It has a simple structure and a low overall structural cost.
