DETAILED DESCRIPTION

[0038] 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.

[0039] like Figure 1-7 As shown, the embodiment of the present invention provides a water tank assembly and a humidifier having the water tank assembly. It is understandable that the water tank assembly of the embodiment of the present invention is not limited to being used in humidifiers, but can also be used in other devices and occasions with similar requirements.

[0040] The water tank assembly of the embodiment of the utility model is first described below.

[0041] like Figure 1 and Figure 2 As shown, the water tank assembly 100 of the embodiment of the utility model includes a water tank 1, a heating element 2, a mounting member 3, a temperature sensor 4 and a sealing member 5. The water tank 1 has a water cavity 11 extending in the up and down directions. The water tank 1 has a bottom wall 12 and a peripheral wall 13. The bottom wall 12 is provided with a mounting hole 121. The mounting hole 121 passes through the bottom wall 12 along the thickness direction of the bottom wall 12. The heating element 2 is provided on the bottom wall 12 of the water tank 1 and is used to heat the water in the water cavity 11. The mounting member 3 is located outside the water cavity 11 and is detachably engaged in the mounting hole 121. The temperature sensor 4 is mounted on the mounting member 3 and extends into the water cavity 11. The temperature sensor 4 is used to detect the water temperature in the water cavity 11.

[0042] In the water tank assembly of the embodiment of the present invention, the temperature sensor 4 is detachably engaged in the mounting hole 121 through the mounting member 3, so that the temperature sensor 4 can be installed and removed from the outside of the water cavity 11, thereby facilitating installation, removal and replacement. The temperature sensor 4 monitors the degree of heating of the water in the water cavity 11 by the heating element 2 in real time, making it convenient for the user to understand and control the water temperature in the water cavity 11 and improving safety. Moreover, the temperature sensor 4 is arranged at the bottom of the water cavity 11. Regardless of the amount of water in the water cavity 11, the temperature sensor 4 can detect the temperature of the water in the water cavity 11.

[0043] like Figure 3 As shown, the bottom wall 12 is provided with a flange 6, which extends downward from the outer surface of the bottom wall 12, and the mounting hole 121 passes through the flange 6. The inner circumference of the mounting hole 121 is provided with an internal thread, and the outer circumference of the mounting member 3 is provided with an external thread, and the mounting member 3 is threadedly engaged in the mounting hole 121.

[0044] Specifically, the provision of flange 6 increases the area of ​​the inner circumference of mounting hole 121, thereby increasing the contact area between mounting hole 121 and mounting member 3, and improving the fit between mounting member 3 and mounting hole 121. When mounting member 3 is installed in mounting hole 121, mounting member 3 is inserted into mounting hole 121 and threadedly engaged with mounting hole 121, which is simple and easy to operate.

[0045] The water tank assembly 100 also includes a sealing member 5 provided between the mounting member 3 and the bottom wall 12 to seal the gap between the mounting member 3 and the bottom wall 12, ensuring that the mounting member 3 is tightly installed on the water tank 1, and the water in the water cavity 11 is not easy to overflow from between the mounting hole 121 and the mounting member 3, thereby improving the sealing performance of the water tank assembly 100.

[0046] like Figure 3As shown, the outer edge of the lower surface of the flange 6 is provided with an extension portion 61 extending downward. The mounting hole 121 passes through the extension portion 61. The cross-sectional area of ​​the mounting hole 121 formed by the inner circumference of the extension portion 61 is larger than the cross-sectional area of ​​the mounting hole 121 formed by the inner circumference of the flange 6. At least a portion of the mounting member 3 fits within the extension portion 61 and abuts against the inner circumference of the extension portion 61, further increasing the contact area between the mounting member 3 and the mounting hole 121, improving the fit and ensuring that the mounting member 3 is securely installed within the mounting hole 121. The mounting member 3 fitted within the extension portion 61 can abut against the lower surface of the flange 6 to limit the position of the mounting member 3. The seal 5 is located within the extension portion 61 and is provided between the lower surface of the flange 6 and the mounting member 3. The flange 6 and the mounting member 3 squeeze the seal 5, ensuring that the seal 5 is securely installed and improving the sealing effect.

[0047] like Figure 4 As shown, the mounting member 3 includes a mounting portion 31 and a mating portion 32. An external thread is formed on the outer circumferential surface of the mounting portion 31 of the mounting member 3. The mounting portion 31 is threadedly engaged in the mounting hole 121, and the mating portion 32 is engaged in the extending portion 61. The sealing member 5 is located between the upper surface of the mating portion 32 and the lower surface of the flange 6.

[0048] Specifically, the mounting portion 31 is threadedly engaged in the mounting hole 121, and the upper end of the engaging portion 32 is engaged in the extending portion 61. When the mounting member 3 is installed in the mounting hole 121, the mounting portion 31 is threadedly engaged in the mounting hole 121 by rotating the lower end of the engaging portion 32. This operation is simple and further improves the engagement of the mounting member 3 in the mounting hole 121, ensuring that the mounting member 3 is securely mounted in the mounting hole 121. The mounting member 3 has a simple structure, saving manufacturing costs.

[0049] The seal 5 is arranged around the outer circumference of the lower end of the mounting portion 31. As the mounting portion 31 is screwed into the mounting hole 121, the seal 5 is gradually squeezed, so that the seal 5 is firmly installed and not easily displaced, thereby ensuring the sealing effect.

[0050] like Figure 3 As shown, the mounting member 3 has a through hole 33 that extends vertically through the mounting portion 31 and the mating portion 32. The cross-sectional area at the lower end of the through hole 33 is smaller than the cross-sectional area at other locations of the through hole 33. The temperature sensor 4 is sealed within the through hole 33. The upper end of the temperature sensor 4 extends from the upper end of the through hole 33 into the water chamber 11, and the lower end of the temperature sensor 4 extends from the lower end of the through hole 33.

[0051] Specifically, the temperature sensor 4 is inserted into the through hole 33, and the outer circumference of the temperature sensor 4 is closely aligned with the inner circumference of the through hole 33, so that the water in the water cavity 11 is unlikely to leak out from between the outer circumference of the temperature sensor 4 and the inner circumference of the through hole 33. Furthermore, the installation method is simple, and the method for detachably mounting the temperature sensor 4 on the water tank 1 is simple. The upper end of the temperature sensor 4 extends into the water cavity 11 and directly contacts the water cavity 11, which can more accurately detect the temperature of the water in the water cavity 11 and improve the accuracy of the detection.

[0052] like Figure 2 As shown, the bottom wall 12 has a downwardly concave recess 122 located in the middle of the bottom wall 12, and the heating element 2 is disposed at the bottom of the recess 122. The provision of the recess 122 increases the volume of the water cavity 11, and the provision of the heating element 2 at the bottom of the recess 122 improves space utilization. The heating element 2 first heats the water in the recess 122, and the hot water in the recess 122 then transfers heat to the water in other locations, ensuring that the water tank 1 is not easily deformed or ruptured due to rapid changes in water temperature.

[0053] The mounting holes 121 are located around the bottom wall 12 , so the temperature sensor 4 is located around the bottom wall 12 and away from the recess 122 . This prevents the temperature sensor 4 from being affected by the water temperature in the recess 122 when measuring the water temperature, which would result in inaccurate measurement results. In addition, the temperature sensor 4 is protected from operating in a high-temperature environment for a long time, thereby extending the service life of the temperature sensor 4 .

[0054] like Figure 2 As shown, the water tank assembly 100 also includes a base 7, and the peripheral wall 13 of the water tank 1 includes an upper peripheral wall section 131 and a lower peripheral wall section 132. The upper peripheral wall section 131 is located above the bottom wall 12, and the lower peripheral wall section 132 is located below the bottom wall 12. The upper peripheral wall section 131 and the bottom wall 12 enclose a water cavity 11, and the base 7 is installed at the lower end of the lower peripheral wall section 132. The base 7, the lower peripheral wall section 132 and the bottom wall 12 enclose a mechanical cavity 14.

[0055] Specifically, the upper and lower wall sections 131, 132 are integrally formed, ensuring the integrity of the outer circumference of the water tank 1 and enhancing its structural strength. The bottom wall 12 divides the interior of the water tank 1 into a water chamber 11 and a mechanical chamber 14. The components on the base 7 are located within the mechanical chamber 14, improving space utilization in the water tank 1. The water tank 1 has a simple structure, reducing manufacturing costs.

[0056] In other words, the mounting member 3 is located in the mechanical cavity 14. By removing the base 7, the temperature sensor 4 can be conveniently installed, removed and replaced from the mechanical cavity 14 below the bottom wall 12. At the same time, the mechanical cavity 14 provides a protective space for the mounting member 3 to avoid damage.

[0057] like Figure 5As shown, the outer edge of the lower surface of the lower peripheral wall section 132 is provided with an outer edge portion 1321 extending downward. The base 7 includes a surrounding wall 71, and the inner edge of the upper surface of the surrounding wall 71 is provided with a first inner edge portion 72 extending upward. The inner edge of the upper surface of the first inner edge portion 72 of the surrounding wall 71 is provided with a second inner edge portion 73 extending upward. The wall thickness of the second inner edge portion 73 is less than that of the first inner edge portion 72, and the wall thickness of the first inner edge portion 72 is less than that of the surrounding wall 71. The second inner edge portion 73 fits within the surrounding wall 71, and the first inner edge portion 72 fits within the outer edge portion 1321. The upper surface of the first inner edge portion 72 abuts against the lower surface of the surrounding wall 71, and the lower surface of the outer edge portion 1321 abuts against the upper surface of the surrounding wall 71. This improves the fit between the base 7 and the lower peripheral wall section 132, ensuring that the base 7 is securely installed.

[0058] like Figure 1 As shown, the water tank assembly 100 also includes a display screen 8, which is used to display the temperature of the water in the water cavity 11 detected by the temperature sensor 4, so that the user can intuitively understand the temperature of the water in the water cavity 11 through the display screen 8, thereby improving safety and user satisfaction.

[0059] The humidifier according to the embodiment of the present invention is described below.

[0060] The humidifier 200 according to the embodiment of the present invention includes a water tank assembly 100 .

[0061] In the humidifier of the embodiment of the present invention, the water tank assembly 100 can detect and observe the water temperature in real time with high accuracy and good sealing, so that the humidifier 200 can detect and control the water temperature in real time, thereby improving safety during use and having a good sealing effect.

[0062] like Figure 6 and Figure 7 As shown, the water tank assembly 100 also includes a tank cover 9. Specifically, the tank cover 9 covers the top of the water tank 1 to seal the upper opening of the water tank 1. A water filling hole 91 is provided on the tank cover 9. The tank cover 9 is gradually concave from the periphery toward the center. The tank cover 9 includes a cover plate 92 and a lower edge plate 93. The lower edge plate 93 is arranged around the circumference of the cover plate 92. The outer edge of the cover plate 92 protrudes from the outer circumference of the lower edge plate 93, and the lower edge plate 93 fits within the water tank 1.

[0063] A latching protrusion 15 is provided on the inner peripheral wall 13 of the upper end of the water tank 1 , and a latching groove 94 is provided on the tank cover 9 to cooperate with the latching protrusion 15 so as to install the tank cover 9 on the upper end of the water tank 1 .

[0064] Specifically, a plurality of latching protrusions 15 are provided on the inner circumferential wall 13 at the upper end of the water tank 1, and are spaced apart around the circumference of the water tank 1. A plurality of latching slots 94 are provided on the lower edge plate 93, and are spaced apart around the circumference of the lower edge plate 93. One end of the latching slot 94 communicates with the lower end of the lower edge plate 93, and the other end of the latching slot 94 extends upward and along the circumference of the lower edge plate 93. The other end of the latching slot 94 has a bottom surface, and the bottom surface of the other end of the latching slot 94 is provided with a groove 941, which penetrates the lower edge plate 93 in the radial direction.

[0065] When installing the box cover 9 on the water tank 1, first insert the lower edge plate 93 into the upper end of the water tank 1, and then rotate the box cover 9 so that the locking protrusion 15 moves from one end of the locking groove 94 to the other end of the locking groove 94 along the extension direction of the locking groove 94 and engages with the groove 941, thereby realizing a detachable connection between the box cover 9 and the water tank 1, which is convenient to install and has a simple matching method.

[0066] like Figure 7 As shown, the humidifier 200 includes a mist outlet pipe 10 and a mist outlet cap 20. The mist outlet cap 20 is arranged on the upper surface of the box cover 9 and the outer peripheral surface of the mist outlet cap 20 is provided with a mist outlet hole 30. The mist outlet pipe 10 is located in the water cavity 11 and the upper end of the mist outlet pipe 10 is connected to the box cover 9.

[0067] Specifically, the water in the water cavity 11 is atomized through the mist outlet pipe 10 and discharged from the mist outlet cap 20 . There are multiple mist outlet holes 30 , which are arranged at intervals around the circumference of the mist outlet cap 20 , thereby improving the mist outlet efficiency of the humidifier 200 .
