Detailed Implementation

[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] like Figure 1-7 As shown, embodiments of this utility model provide a water tank and a humidifier having the water tank. It is understood that the water tank of this utility model embodiment is not limited to use in humidifiers, but can also be used in other devices and occasions with similar needs.

[0041] The water tank of this utility model embodiment will be described first below.

[0042] like Figure 1-3 As shown, the water tank 100 of this embodiment includes a tank body 1 and a heating device 2. The tank body 1 has a water cavity 11. The heating device 2 is detachably mounted on the bottom wall of the water cavity 11. The heating device 2 has a heating chamber 211, which has a water inlet 212 and a steam outlet. The water inlet 212 communicates with the water cavity 11, and the top surface of the heating chamber 211 is open to form a steam outlet.

[0043] The water tank in this embodiment of the invention features a heating chamber 211, which allows scale generated by the heating device 2 to concentrate within the chamber, reducing scale diffusion. The heating device 2 is detachably mounted on the bottom wall, facilitating easy removal for cleaning and replacement, saving time and effort. Water from the water chamber 11 enters the heating chamber 211 through the inlet 212. The heating device 2 heats the water in the heating chamber 211 and generates steam, reducing the amount of water required for heating, lowering energy consumption, and improving heating efficiency.

[0044] Optionally, such as Figure 3 As shown, the steam outlet and water inlet 212 are the same opening and are formed by the open top surface of the heating chamber 211. Specifically, both the steam outlet and water inlet 212 are formed at the upper end of the heating chamber 211, which facilitates the entry of water from the water chamber 11 into the heating chamber 211 and the exit of steam generated in the heating chamber 211. Moreover, it is simple to manufacture, reduces the processing of the heating device 2, makes the production of the heating device 2 easier, and also ensures the structural integrity and structural strength of the heating device 2.

[0045] Optionally, such as Figure 1-2 As shown, the heating device 2 includes a housing 21 and a heating element 22. The housing 21 is detachably disposed on the bottom wall of the water cavity 11, the heating element 22 is disposed inside the housing 21, and the heating cavity 211 is formed inside the housing 21.

[0046] Specifically, the top surface of the housing 21 is recessed downwards to form a heating cavity 211. The heating element 22 is disposed inside the heating cavity 211 to heat the water entering the housing 21. This reduces the amount of water that the heating element 22 needs to heat, saving energy. Furthermore, the scale generated from heating the water can be concentrated inside the housing 21. The housing 21 is detachably mounted on the bottom wall of the water cavity 11, making it easy to remove the housing 21 from the bottom wall of the water cavity 11 for centralized cleaning of scale inside the housing 21. This process is simple and efficient. In addition, the heating device 2 has a simple structure, saving manufacturing costs.

[0047] Optionally, such as Figure 2 As shown, the bottom wall of the water cavity 11 is provided with a mounting hole 111. The upper end of the housing 21 fits into the mounting hole 111 and is detachably connected to the bottom wall of the water cavity 11. The lower end of the housing 21 extends downward from the mounting hole 111, so that the heating chamber 211 inside the housing 21 is located below the water cavity 11, ensuring that water in the water cavity 11 can easily flow into the heating chamber 211. The top surface of the heating element 22 is roughly flush with the bottom wall of the water cavity 11, and the lower end of the heating element 22 is located below the bottom wall of the water cavity 11, so that the heating element 22 can heat only the water in the heating chamber 211, saving energy consumption. Moreover, it also increases the utilization rate of the water cavity 11's volume, allowing the water cavity 11 to hold more water, reducing the frequency of users adding water to the water cavity 11, and improving user satisfaction.

[0048] Optionally, such as Figure 1-2 As shown, the upper end of the housing 21 has a connecting part 213, and the bottom wall of the water cavity 11 has a threaded hole 112. A screw 113 is provided in the threaded hole 112. The screw 113 can pass through the connecting part 213 and is threaded in the threaded hole 112.

[0049] Specifically, there are multiple connecting portions 213, which are arranged circumferentially around the upper end of the housing 21 and extend outward from the outer edge of the upper end of the housing 21. When the housing 21 is installed in the mounting hole 111, the lower surface of the connecting portion 213 contacts the upper surface of the bottom wall of the water cavity 11, so that the housing 21 can be supported in the mounting hole 111 through the connecting portion 213.

[0050] like Figure 2 As shown, the connecting part 213 has a through hole 214, which penetrates the connecting part 213 along its thickness direction. Multiple threaded holes 112 are arranged at intervals around the mounting hole 111. Each threaded hole 112 corresponds to one of the multiple through holes 214. Screws 113 pass through the through holes 214 and engage within the threaded holes 112 to connect the connecting part 213 to the bottom wall of the water cavity 11. This allows for a detachable connection of the housing 21 to the bottom wall of the water cavity 11, and the connection method is simple and robust.

[0051] Optionally, such as Figure 2and Figure 5 As shown, the upper end of the housing 21 also has an extension 215. The extension 215 extends outward around the outer edge of the upper end of the housing 21. The connecting part 213 is provided on the extension 215 and extends outward from the outer edge of the extension 215. The upper surface of the connecting part 213 is flush with the upper surface of the extension 215. The thickness of the extension 215 is greater than the thickness of the connecting part 213.

[0052] like Figure 4 As shown, the inner circumferential surface of the mounting hole 111 is provided with a protrusion 114. The protrusion 114 is arranged around the circumference of the mounting hole 111. The protrusion 114 extends inward from the lower inner circumferential surface of the mounting hole 111, and the lower end of the extension 215 fits in the through hole 241.

[0053] Optionally, such as Figure 4 As shown, a first sealing element 23 is provided between the connecting part 213 and the bottom wall of the water cavity 11, and the first sealing element 23 is arranged circumferentially around the mounting hole 111.

[0054] Specifically, the first seal 23 is located between the lower surface of the extension 215 and the upper surface of the protrusion 114. The extension 215 and the protrusion 114 press against the seal, which strengthens the seal between the housing 21 and the bottom wall of the water cavity 11, ensuring that the water in the water cavity 11 does not easily flow out from the gap between the housing 21 and the mounting hole 111.

[0055] Optionally, such as Figure 3 and Figure 5 As shown, the heating device 2 also includes a pressure plate 24 and a second sealing element 25. The pressure plate 24 has a through hole 241, which is located in the middle of the pressure plate 24 and passes through the pressure plate 24. The heating element 22 passes through the through hole 241. The heating element 22 has a flange 221. The upper end of the pressure plate 24 is located above the flange 221 and abuts against the upper surface of the flange 221. The lower end of the pressure plate 24 is connected to the bottom wall of the housing 21 to ensure that the heating element 22 is stably installed in the housing 21.

[0056] The second seal 25 is located between the pressure plate 24 and the bottom wall of the housing 21. The lower end of the second seal 25 is clamped between the lower end of the pressure plate 24 and the bottom wall of the housing 21, and the upper end of the second seal 25 is clamped between the upper end of the pressure plate 24 and the upper surface of the flange 221.

[0057] Specifically, by providing a second sealing element 25, the seal between the heating element 22 and the bottom wall of the housing 21 is strengthened, making the connection between the pressure plate 24 and the heating element 22 tight, ensuring that the heating element 22 is not prone to shaking in the perforation 241. Moreover, the second sealing element 25 extends along the outer surface of the flange portion 221, which not only extends the extension area of ​​the second sealing element 25, but also further ensures the sealing effect of the heating element 22 installed in the housing 21.

[0058] Optionally, such as Figure 3 As shown, at least a portion of the heating device 2 is located outside the water cavity 11, and at least a portion of the heating cavity 211 is lower than the lowest point of the bottom surface of the water cavity 11, so that the water in the water cavity 11 can easily flow into the heating cavity 211. The heating element 22 can heat only the water in the heating cavity 211, saving energy consumption, increasing the utilization rate of the volume of the water cavity 11, allowing the water cavity 11 to hold more water, reducing the frequency of users adding water to the water cavity 11, and improving user satisfaction.

[0059] Optionally, such as Figure 1 and Figure 3 As shown, the water tank 100 also includes a base 3, which is located at the lower end of the tank body 1. The bottom wall of the water cavity 11 divides the tank body 1 into a water cavity 11 located above the bottom wall and a mechanical cavity 12 located below the bottom wall. The lower end of the heating device 2 is located in the mechanical cavity 12.

[0060] Optionally, such as Figure 6 As shown, the heating element 22 has a conductive sheet 222 that extends from the bottom wall of the housing 21. The heating device 2 also includes a support plate 26 and a conductive plate 27. The support plate 26 is located below the housing 21 and connected to the bottom wall of the water cavity 11. The support plate 26 has a conductive hole 261. The conductive plate 27 is located on the bottom surface of the support plate 26, and at least a portion of the conductive plate 27 can pass through the conductive hole 261 and contact the conductive sheet 222.

[0061] Specifically, if Figure 6 As shown, the bottom wall of the housing 21 has a through hole 216, allowing the conductive sheet 222 located on the bottom surface of the heating element 22 to extend through the through hole 216 and contact the conductive plate 27. This facilitates the conductive plate 27 supplying power to the conductive sheet 222, enabling the heating element 22 to operate. The operation is simple and effective. The conductive plate 27 is positioned below the housing 21 via a support plate 26 to facilitate contact with the conductive sheet 222. The installation method is simple and easy to implement.

[0062] Optionally, such as Figure 3 As shown, the support plate 26 has a groove 262, a conductive hole 261 is formed on the bottom surface of the groove 262, a conductive plate 27 is disposed in the groove 262, and a locking block 263 is provided on the bottom surface of the groove 262, which engages with the conductive plate 27.

[0063] Specifically, the groove 262 protrudes upward from the bottom surface of the support plate 26 and is located in the middle of the bottom surface of the support plate 26. The conductive hole 261 is formed on the bottom surface of the groove 262. By placing the conductive plate 27 in the groove 262, the conductive plate 27 can be protected. There are multiple locking blocks 263, which are arranged at intervals along the circumference of the groove 262. When the conductive plate 27 is installed, the locking blocks 263 lock the conductive plate 27 to ensure that the conductive plate 27 is installed firmly in the groove 262, thereby ensuring good contact between the conductive plate 27 and the conductive sheet 222 of the heating element 22. The installation method is simple and the operation is convenient.
