[0004] An embodiment of this utility model also proposes a humidifier having the above-described embodiments.

[0005] The water tank of this utility model embodiment includes:

[0006] The container has a drain hole on its wall for draining water from the container, and the drain hole penetrates the container wall along the thickness direction of the container wall.

[0007] A drainage assembly includes a sealing part and an operating part. The sealing part is used to seal the discharge hole. The sealing part and the operating part are connected. The sealing part is driven by the operating part to move between an open position and a closed position. In the open position, the sealing part is spaced apart from the discharge hole so that water in the tank can be discharged through the discharge hole. In the closed position, the sealing part seals the discharge hole.

[0008] The water tank of this utility model uses an operating part to drive the sealing part to move between an open position and a closed position, thereby opening or closing the drain hole. When the sealing part and the drain hole are spaced apart, the drain hole is opened, and the water in the tank can be discharged through the drain hole. The operation is convenient and the drainage is easy. When the sealing part is in close contact with the inner wall of the tank, the sealing part closes the drain hole and stops the drainage. Therefore, the drainage operation in the water tank is convenient and simple.

[0009] Optionally, the housing wall is further provided with a mounting hole that penetrates the housing wall along the thickness direction. The sealing part is located inside the housing, and the operating part is fitted into the mounting hole and can move axially along the mounting hole. At least a portion of the operating part is located outside the housing.

The elastic element is disposed between the housing and the second end of the operating lever to press the operating lever in a direction away from the housing.

[0014] In this embodiment of the water tank, the second end of the operating rod is located outside the tank body. The operating rod can be moved by operating the second end, which is convenient. The elastic element presses the operating rod away from the tank body to apply a force to the operating rod away from the tank body, ensuring that the sealing part provided at the first end of the operating rod can be tightly attached to the wall of the tank body inside the tank body, thus ensuring a sealing effect.

[0015] Optionally, the operating lever includes a main body segment, a grooved segment, and a lever head that are sequentially connected along its axial direction from the second end to the first end. An annular groove is formed between the lever head and the main body segment, surrounding the grooved segment. The sealing part has a mating hole, and at least a portion of the grooved segment mates with the mating hole.

[0016] In this embodiment of the water tank, the sealing part is fitted into the annular groove. The rod head and the main rod segment can limit the sealing part, so that the sealing part is firmly installed on the groove rod segment. This ensures that the sealing part can move together with the operating rod when it moves in the mounting hole, which improves the accuracy of operation. Moreover, the structure of the operating rod is simple, easy to manufacture, and saves costs.

[0017] Optionally, the mating hole includes a first mating hole section and a second mating hole section located inside the first mating hole section. The second mating hole section has a non-circular cross-section, and the grooved rod section has a cross-section adapted to the second mating hole section. The grooved rod section mates with the second mating hole, and the first mating hole section mates with the main rod section.

[0018] In this embodiment of the water tank, the second mating hole section has a non-circular cross-section, and the cross-section of the grooved rod section is adapted to the cross-section of the second mating hole section, which improves the fit of the grooved rod section in the second mating hole, making it difficult for the grooved rod section and the sealing part to rotate relative to each other, ensuring that the sealing part is installed stably at the grooved rod section. The main rod section fits in the first mating hole section, thereby further improving the fit between the operating rod and the sealing part.

[0019] Optionally, the operating unit further includes a handle, which is disposed at the second end of the operating lever.

[0020] The water tank in this embodiment of the utility model has a handle that facilitates operation of the control lever.

[0021] Optionally, the elastic element is a spring fitted onto the operating lever.

[0022] The water tank of this utility model embodiment uses a spring as the elastic element, which is simple in structure, easy to install, convenient to use, and low in cost.

[0023] Optionally, the outer wall of the housing is provided with an inwardly recessed groove, the mounting hole is located on the bottom surface of the groove, and a protrusion is provided in the groove surrounding the mounting hole and extending outward from the outer wall of the housing. At least a portion of the operating part located outside the housing is located inside the protrusion.

[0024] The water tank of this utility model embodiment, by setting at least a portion of the operating part located outside the tank body inside the protrusion, makes at least a portion of the operating part less susceptible to movement by other external forces, keeps the sealing part stable, and protects at least a portion of the operating part located outside the tank body.

[0040] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] like Figure 1-10 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.

[0042] The water tank of this utility model embodiment will be described first below.

[0043] like Figure 1 As shown, the water tank 100 of this utility model embodiment includes a tank body 1 and a drainage assembly 2. The tank body 1 has a discharge hole 11 on its wall, which is used to discharge water from the tank body 1. The discharge hole 11 penetrates the tank wall along the thickness direction of the tank wall.

[0044] The drainage assembly 2 includes a sealing part 21 and an operating part 22. The sealing part 21 seals the discharge hole 11, and the sealing part 21 and the operating part 22 are connected. By moving the operating part 22, the sealing part 21 can be moved between an open position and a closed position. In the open position, the sealing part 21 is spaced apart from the discharge hole 11, that is, the sealing part 21 is spaced apart from the tank wall of the tank body 1, so that water in the tank body 1 can flow into the gap between the sealing part 21 and the tank wall and be discharged through the discharge hole 11. In the closed position, the sealing part 21 is in close contact with the tank wall to close the discharge hole 11, so that water in the tank body 1 is not easily allowed to flow out from the discharge hole 11.

[0045] In this embodiment of the water tank, the operation unit 22 moves to drive the sealing part 21 between an open position and a closed position, thereby opening or closing the discharge hole 11. When the sealing part 21 and the discharge hole 11 are spaced apart, the discharge hole 11 is open, and water in the tank 1 can be discharged through the discharge hole 11, making operation convenient and drainage easy. When the sealing part 21 is in close contact with the inner wall of the tank 1, the sealing part 21 closes the discharge hole 11, stopping drainage. Therefore, the drainage operation in the water tank 100 is convenient and simple.

[0046] It is understandable that the sealing part 21 and the operating part 22 can be integrally formed or separate parts.

[0047] Specifically, such as Figure 2 As shown, there are at least two discharge holes 11, which are arranged at intervals to improve the discharge efficiency of water in the water tank 100.

[0048] Optionally, such as Figure 2 As shown, the housing 1 is also provided with mounting holes 12 on its wall. The mounting holes 12 penetrate the housing wall along its thickness direction and are spaced apart from the discharge holes 11. The sealing part 21 is located inside the housing 1, and the operating part 22 is fitted into the mounting hole 12 and can move axially along the mounting hole 12. At least a part of the operating part 22 is located outside the housing 1.

[0049] Specifically, at least two discharge holes 11 are arranged circumferentially around the mounting hole 12. The sealing part 21 is located inside the housing 1. When the sealing part 21 closes the discharge holes 11, the water inside the housing 1 can provide pressure to the sealing part 21, making the sealing part 21 fit more tightly against the housing wall. The operating part 22 is fitted inside the mounting hole 12, which improves the fit between the operating part 22 and the housing 1, ensuring the stability of the operating part 22 on the housing 1. Moreover, the sealing part 21 is operated by operating the operating part 22 located outside the housing 1, making the operation simple and convenient.

[0050] Optionally, such as Figure 2 As shown, the water tank 100 also includes a flange portion 3, which is disposed on the inner wall surface of the tank body 1 and is arranged circumferentially around the discharge hole 11. The flange portion 3 has a channel 31 communicating with the inner cavity of the tank body 1, and a sealing portion 21 is disposed in the channel 31, with the outer peripheral surface of the sealing portion 21 and the inner peripheral surface of the channel 31 arranged at intervals.

[0051] Specifically, the flange 3 is circumferentially arranged around the mounting hole 12, the drain hole 11 is located inside the flange 3, and the channel 31 guides the movement of the sealing part 21, ensuring that the sealing part 21 remains stable when moving between the open and closed positions, preventing it from tilting, and ensuring the drainage efficiency of the drain hole 11 and the sealing effect of the sealing part 21 on the drain hole 11. The outer peripheral surface of the sealing part 21 and the inner peripheral surface of the channel 31 are spaced apart to ensure that water in the tank 1 can flow through the gap between the sealing part 21 and the channel 31 and flow out through the drain hole 11.

[0052] Optionally, such as Figure 1 , Figure 4 and Figure 6 and Figure 9 As shown, the operating part 22 includes an operating lever 221 and an elastic element 222. The operating lever 221 fits into the mounting hole 12. The first end of the operating lever 221 passes through the mounting hole 12 and is located inside the housing 1, connected to the sealing part 21. The sealing part 21 is in close contact with the inner wall surface of the housing 1. The second end of the operating lever 221 is located outside the housing 1, facilitating movement of the operating lever 221 by operating the second end. The elastic element 222 is provided between the housing 1 and the second end of the operating lever 221 to press the operating lever 221 away from the housing 1, thereby applying a force to the operating lever 221 in a direction away from the housing 1. This ensures that the sealing part 21 located at the first end of the operating lever 221 can be in close contact with the wall surface of the housing 1 inside the housing 1, ensuring a sealing effect.

[0053] Optionally, such as Figure 9 As shown, the operating lever 221 includes a main lever segment 2211, a grooved lever segment 2212, and a lever head 2213 connected sequentially along its axial direction from the second end to the first end. An annular groove 2214 surrounding the grooved lever segment 2212 is formed between the lever head 2213 and the main lever segment 2211. The sealing part 21 has a mating hole 211, and at least a portion of the grooved lever segment 2212 mates with the mating hole 211.

[0054] Specifically, the cross-sectional area of ​​the main rod segment 2211 is larger than the cross-sectional area of ​​the grooved rod segment 2212, and the cross-sectional area of ​​the end of the rod head 2213 adjacent to the grooved rod segment 2212 is larger than the cross-sectional area of ​​the grooved rod segment 2212. An annular groove 2214 is formed between the end face of the main rod segment 2211 adjacent to the grooved rod segment 2212, the outer peripheral surface of the grooved rod segment 2212, and the end face of the rod head 2213 adjacent to the grooved rod segment 2212.

[0055] A portion of the sealing part 21 is fitted into the annular groove 2214, while the other portion fits onto the main body rod segment 2211. The rod head 2213 and the main body rod segment 2211 can limit the sealing part 21, ensuring its stable installation on the groove rod segment 2212. This guarantees that the sealing part 21 can move along with the operating rod 221 when it moves within the mounting hole 12, improving operational accuracy. Furthermore, it ensures a tight and reliable seal between the sealing part 21 and the inner wall of the housing 1, enhancing the sealing effect. In addition, the operating rod 221 has a simple structure, is easy to manufacture, and saves costs.

[0056] Optionally, such as Figure 7 As shown, the mating hole 211 includes a first mating hole section 2111 and a second mating hole section 2112, with the second mating hole section 2112 located inside the first mating hole section 2111. The second mating hole section 2112 has a non-circular cross-section, and the grooved rod section 2212 has a cross-section adapted to the second mating hole section 2112. The grooved rod section 2212 mates with the second mating hole 211, improving the fit of the grooved rod section 2212 within the second mating hole 211 and making it less likely for the grooved rod section 2212 and the sealing part 21 to rotate relative to each other. The first mating hole section 2111 mates with the main rod section 2211.

[0057] Specifically, the outer peripheral surface of the grooved rod segment 2212 includes a first flat surface 22121, a first arcuate surface (not shown), a second flat surface 22122, and a second arcuate surface (not shown) connected sequentially along the circumference of the grooved rod segment 2212. The first flat surface 22121 and the second flat surface 22122 are arranged opposite to each other, and the first arcuate surface and the second arcuate surface are arranged opposite to each other. The inner peripheral contour of the second mating hole segment 2112 is adapted to the outer peripheral contour of the grooved rod segment 2212.

[0058] The cross-sectional area of ​​the first mating hole section 2111 is larger than that of the second mating hole section 2112. One end of the main body rod section 2211 adjacent to the groove rod section 2212 is fitted into the first mating hole section 2111, which limits the sealing part 21 in the extension direction of the main body rod section 2211, further improving the fit between the operating rod 221 and the sealing part 21.

[0059] Optionally, such as Figure 8 and Figure 9 As shown, the operating unit 22 also includes a handle 223, which is located at the second end of the operating lever 221 to facilitate the operation of the operating lever 221.

[0060] Optionally, the elastic element 222 is a spring sleeved on the operating rod 221, which has a simple structure, is easy to install, convenient to use, and has low cost.

[0061] Specifically, a spring is wound around the main rod segment 2211 and extends along the length of the main rod segment 2211. One end of the spring abuts against the wall of the housing 1, and the other end of the spring abuts against the end of the main rod segment 2211 away from the rod head 2213. The spring is in a compressed state, so that the spring can exert a force on the second end of the operating rod 221 in a direction away from the housing 1, so that the first end of the operating rod 221 is also subjected to a force in a direction away from the housing 1, thereby ensuring that the sealing part 21 can be tightly attached to the wall of the housing 1 inside the housing 1, ensuring airtightness. In addition, the elastic element 222 has a simple structure, is easy to use, and has low cost.

[0062] In other embodiments, the elastic element 222 may also be a tensioner, a rubber rope, an elastic rubber block, etc.

[0063] Optionally, such as Figure 1-6 As shown, the outer wall of the housing 1 is provided with an inwardly recessed groove 13, and the mounting hole 12 is provided on the bottom surface of the groove 13. The groove 13 is provided with a protrusion 14 that surrounds the mounting hole 12 and extends outward from the outer wall of the housing 1, and at least part of the operating part 22 located outside the housing 1 is located inside the protrusion 14.

[0064] Specifically, the end of the main body rod segment 2211 of the operating part 22 away from the rod head 2213 extends out of the housing 1 through the mounting hole 12 and is located inside the protrusion 14. The end of the handle 223 adjacent to the main body rod segment 2211 is also located inside the protrusion, so as to ensure that the main body rod segment 2211 is not easily moved by other external forces, keep the sealing part 21 stable, and protect the part of the main body rod segment 2211 outside the housing 1. The setting of the recess 13 makes the surface of the housing 1 look flat and beautiful.

[0065] Optionally, such as Figure 10 As shown, the water tank 100 also includes a tank cover 4, a heating element 5, and a base 6. The tank cover 4 is used to cover the top of the tank body 1. The water tank 100 has a bottom wall 15 and a peripheral wall 16. The peripheral wall 16 includes an upper peripheral wall section 161 located above the bottom wall 15 and a lower peripheral wall section 16 located below the bottom wall 15. The heating element 5 is disposed on the bottom wall 15 of the water tank 100 and is used to heat the water in the water tank 100. The base 6 is connected to the lower end of the lower peripheral wall section 16. The base 6, the lower peripheral wall section 16, and the bottom wall 15 enclose a mechanical cavity 17.

[0066] Specifically, the lid 4 is detachably attached to the top of the tank body 1 by a snap-fit ​​mechanism to cover the upper opening of the tank body 1. The lid 4 has a water filling hole (not shown), and the lid 4 is gradually recessed from the outer periphery towards the center to facilitate the addition of water into the tank body 1. By setting the lid 4, water in the tank body 11 is less likely to overflow, ensuring the safety of the water tank 100 during use.

[0067] The water tank 100 is separated into a mechanical cavity 17 by the bottom wall 15. The components on the base 6 are located inside the mechanical cavity 17, and the heating element 5 is located on the bottom wall 15. This improves the utilization of the space in the water tank 100. Moreover, the structure of the water tank 100 is simple, saving manufacturing costs.

[0068] The humidifier of this utility model embodiment will be described below first.

[0069] like Figure 10 As shown, the humidifier 200 of this utility model embodiment includes a water tank 100, a mist outlet pipe 7, and a mist outlet cap 8. The mist outlet cap 8 is disposed on the top of the box cover 4, and the outer peripheral surface of the mist outlet cap 8 is provided with a mist outlet hole 81. The mist outlet pipe 7 is located inside the box body 1, and the upper end of the mist outlet pipe 7 is connected to the box cover 4. The water in the box body 1 is atomized through the mist outlet pipe 7 and discharged from the mist outlet cap 8.
