Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, specifically to a water tank and a humidifier. Background Technology

[0002] With economic development and improved living standards, humidifiers are becoming increasingly popular. However, in some technologies, draining the water tank typically involves opening the lid first, then lifting the tank to empty it, which is laborious. Furthermore, water can easily splash and wet surfaces during this process. If the water is hot, there is a risk of burns. Additionally, there is a possibility that water flowing along the outer wall of the tank to the bottom could come into contact with conductive components, causing an electrical leak and threatening user safety. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a water tank that is convenient for drainage, saves time and effort during drainage, and offers high safety.

[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: a tank body, wherein the tank body has a first discharge hole on its wall for discharging water from the tank body, the first discharge hole penetrating the tank wall along its thickness direction; and a drainage assembly, wherein the drainage assembly includes a sealing part and an operating part, the sealing part has a second discharge hole, the sealing part is connected to the operating part, and the sealing part is driven by the operating part to rotate between an open position and a closed position, wherein in the open position, the second discharge hole communicates with the first discharge hole to discharge water from the water tank, and in the closed position, the second discharge hole is offset from the first discharge hole and the first discharge hole is closed by the sealing part.

[0006] The water tank of this utility model allows the operating part to rotate, thereby driving the sealing part to rotate and moving the second discharge hole between the open and closed positions. This opens or closes the first discharge hole, allowing water to drain from the tank. The operation is convenient and drainage is easy, while also improving safety during drainage. The first discharge hole is closed by the sealing part by being offset from the second discharge hole, thus stopping drainage. Therefore, the drainage operation in the water tank is convenient, simple, and highly safe.

[0007] Optionally, the box wall is further provided with a mounting hole, which extends through the box wall along the thickness direction. The operating part fits into the mounting hole and can be operated and rotated from outside the box.

[0008] In this embodiment of the utility model, the operating part of the water tank is fitted into the mounting hole, which improves the fit between the operating part and the tank body and ensures the stability of the operating part when installed on the tank body.

[0009] Optionally, the operating part includes an operating lever and an elastic element. The operating lever is rotatably fitted into the mounting hole. The first end of the operating lever is located inside the housing. The sealing part is installed on the first end of the operating lever. The second end of the operating lever 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.

[0010] 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 rotated by operating the second end, which is convenient. The elastic element presses the operating rod away from the tank body to apply a force away from the tank body to the operating rod, ensuring that the sealing part located 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.

[0011] Optionally, the elastic element is a spring fitted onto the operating lever.

[0012] 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.

[0013] 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.

[0014] 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 rotate together with the operating rod when it rotates 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.

[0015] 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.

[0016] 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 less likely for the grooved rod section and the sealing part to rotate relative to each other. The main rod section fits in the first mating hole section, thereby further improving the fit between the operating rod and the sealing part.

[0017] Optionally, the outer wall of the housing is provided with an inwardly recessed groove, the mounting hole is located inside the bottom wall of the groove, and the portion of the operating part located outside the housing is located inside the groove.

[0018] The water tank of this utility model embodiment, by setting the part of the operating part located outside the tank body in the settling trough, makes the operating part less susceptible to rotation by other external forces, thus maintaining stability and protecting the part of the operating part located outside the tank body. Moreover, the setting of the settling trough makes the exterior of the tank body look flat and beautiful.

[0019] Optionally, the second end of the operating lever is provided with a handle for rotating the operating lever, and the recess is provided with a protrusion surrounding the mounting hole and extending outward from the outer wall of the housing. A portion of the end face of the protrusion is provided with an extension section extending outward along the axial direction of the protrusion. The second end of the operating lever is provided with a flange, which fits in the extension section. The two upper end faces of the extension section constitute a limit for rotating the handle.

[0020] The water tank of this utility model embodiment has a handle at the second end of the operating rod, which facilitates the operation of the operating rod. The convex sleeve protects the operating rod, making it less prone to breakage and extending its service life. The two upper end faces of the extension section can limit the rotation of the handle, limiting the rotation range of the handle and improving the accuracy of operation.

[0021] Optionally, the water tank further includes a heating element and a base. The water tank has a bottom wall and a peripheral wall. The peripheral wall includes an upper peripheral wall section located above the bottom wall and a lower peripheral wall section located below the bottom wall. The heating element is disposed on the bottom wall of the water tank and is used to heat the water in the water tank. The base is connected to the lower end of the lower peripheral wall section. The base, the lower peripheral wall section, and the bottom wall enclose a mechanical cavity.

[0022] The water tank of this utility model embodiment is divided into a mechanical cavity by the bottom wall. The components on the base are located in the mechanical cavity, and the heating element is located on the bottom wall. This improves the utilization of the water tank space. Moreover, the water tank has a simple structure and saves manufacturing costs.

[0023] Optionally, the water tank further includes a tank cover for sealing the top of the tank body.

[0024] The water tank of this utility model embodiment has a lid that seals the top of the tank body, making it difficult for water inside the tank to overflow and ensuring the safety of the water tank during use.

[0025] The humidifier of this utility model embodiment includes the water tank described in any of the above embodiments.

[0026] The humidifier of this utility model embodiment has convenient and time-saving water tank drainage, which makes the humidifier easy to drain, saves time and effort, and improves user satisfaction. Attached Figure Description

[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 1-11 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 and Figure 2 As shown, the water tank 100 of this embodiment includes a tank body 1 and a drainage assembly 2. A first discharge hole 12 is provided on the tank wall of the tank body 1 for discharging water from the tank body 1. The first discharge hole 12 penetrates the tank wall along the thickness direction.

[0043] like Figure 5 As shown, the drainage assembly 2 includes a sealing part 21 and an operating part 22. The sealing part 21 has a second discharge hole 211, and the sealing part 21 is connected to the operating part 22. By rotating the operating part 22, the sealing part 21 can be driven to rotate between an open position and a closed position. In the open position, as shown... Figure 7 As shown, the second drain hole 211 communicates with the first drain hole 12, meaning that the second drain hole 211 and the first drain hole 12 are at least partially aligned, so that water in the water tank 100 can be discharged through the second drain hole 211 and the first drain hole 12. In the closed position, as... Figure 5 As shown, the second discharge hole 211 is offset from the first discharge hole 12, and the first discharge hole 12 is closed by the sealing part 21.

[0044] The water tank of this utility model embodiment can drive the sealing part 21 to rotate by rotating the operating part 22, so that the second discharge hole 211 moves between the open position and the closed position, thereby opening or closing the first discharge hole 12. That is, the second discharge hole 211 is at least partially aligned with the first discharge hole 12 and is opened, and the second discharge hole 211 is misaligned with the first discharge hole 12 so that the first discharge hole 12 is closed by the sealing part 21. The operation is convenient, the drainage is convenient, and the safety during drainage is improved.

[0045] Specifically, the open position is the position of the second discharge hole 211 when it can communicate with (i.e., at least partially aligned with) the first discharge hole 12. The closed position is the position of the second discharge hole 211 when it is offset from the first discharge hole 12 and not connected, and the first discharge hole 12 is closed by the sealing part 21. Preferably, in the open position, the central axis of the second discharge hole 211 is collinear with the central axis of the first discharge hole 12, thereby resulting in a large water flow rate and high discharge efficiency through the second discharge hole 211 and the first discharge hole 12.

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

[0047] Optionally, the housing 1 has mounting holes 11 on its wall, which extend through the wall along its thickness and are spaced apart from the first discharge holes 12. The operating part 22 is fitted into the mounting holes 11 and can be rotated from outside the housing 1. Specifically, the fitting of the operating part 22 into the mounting holes 11 improves the fit between the operating part 22 and the housing 1, ensuring stable installation of the operating part 22 on the housing 1.

[0048] Optionally, such as Figure 5 As shown, the operating part 22 includes an operating lever 221 and an elastic element 222. The operating lever 221 is rotatably fitted in the mounting hole 11. The first end of the operating lever 221 passes through the mounting hole 11 and is located inside the housing 1. The sealing part 21 is installed on the first end of the operating lever 221 and 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, which facilitates the rotation of the operating lever 221 by operating the second end.

[0049] The elastic element 222 is disposed between the housing 1 and the second end of the operating rod 221 to press the operating rod 221 in a direction away from the housing 1, thereby applying a force to the operating rod 221 in a direction away from the housing 1. This ensures that the sealing part 21 disposed at the first end of the operating rod 221 can reliably adhere to the wall surface of the housing 1 inside the housing 1. The sealing effect can be guaranteed regardless of whether the sealing part 21 rotates under the driving action of the operating rod 221.

[0050] Optionally, the elastic element 222 is a spring fitted onto the operating lever 221.

[0051] Specifically, a spring is wound around the operating rod 221 and extends along the length of the operating rod 221. One end of the spring abuts against the wall of the housing 1, and the other end abuts against the second end of the operating rod 221. The spring is in a compressed state, so that it can exert a force on the second end of the operating rod 221 in a direction away from the housing 1. This also causes the first end of the operating rod 221 to be 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.

[0052] In other embodiments, the elastic element 222 may also be a tensioner, a rubber rope, an elastic rubber block, etc.

[0053] Optionally, such as Figure 5 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 212, and at least a portion of the grooved lever segment 2212 mates with the mating hole 212.

[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] like Figure 9 and Figure 10 As shown, a portion of the sealing part 21 is fitted into the annular groove 2214, and the other portion of the sealing part 21 is fitted onto the main body rod segment 2211. The rod head 2213 and the main body rod segment 2211 can limit the sealing part 21, so that the sealing part 21 is firmly installed on the groove rod segment 2212. This ensures that when the operating rod 221 rotates in the mounting hole 11, the sealing part 21 can rotate together with it, improving the accuracy of operation. Moreover, it can ensure that the sealing part 21 is tightly and reliably fitted to the inner wall of the housing 1, improving 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 9As shown, the mating hole 212 includes a first mating hole section 2121 and a second mating hole section 2122, with the second mating hole section 2122 located inside the first mating hole section 2121. The second mating hole section 2122 has a non-circular cross-section, and the grooved rod section 2212 has a cross-section adapted to the second mating hole section 2122. The grooved rod section 2212 mates with the second mating hole 212, improving the fit of the grooved rod section 2212 within the second mating hole 212 and making it less likely for the grooved rod section 2212 and the sealing part 21 to rotate relative to each other.

[0057] Specifically, the outer peripheral surface of the grooved rod segment 2212 includes a first flat surface 22121, a first arcuate surface 22122, a second flat surface (not shown), 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 are arranged opposite to each other, and the first arcuate surface 22122 and the second arcuate surface are arranged opposite to each other. The inner peripheral contour of the second mating hole segment 2122 is adapted to the outer peripheral contour of the grooved rod segment 2212.

[0058] The cross-sectional area of ​​the first mating hole section 2121 is larger than that of the second mating hole section 2122. One end of the main rod section 2211 adjacent to the groove rod section 2212 fits into the first mating hole section 2121, which limits the sealing part 21 in the extension direction of the main rod section 2211, further improving the fit between the operating rod 221 and the sealing part 21.

[0059] Optionally, such as Figure 5 As shown, the outer wall of the housing 1 has an inwardly recessed groove 13. The mounting hole 11 and the first discharge hole 12 are both located on the bottom wall of the groove 13. The portion of the operating part 22 located outside the housing 1 is situated within the groove 13, preventing the operating part 22 from rotating under external forces and maintaining stability. Furthermore, the groove 13 protects the portion of the operating part 22 located outside the housing 1. The groove 13 also makes the exterior of the housing 1 appear flat and aesthetically pleasing.

[0060] Optionally, such as Figures 5-10 As shown, the second end of the operating lever 221 is provided with a handle 2215 for rotating the operating lever 221, which facilitates the operation of the operating lever 221. The settling tank 13 is provided with a protrusion 14 surrounding the mounting hole 11 and extending outward from the outer wall of the tank body 1. The first discharge hole 12 is also located within the protrusion 14. When water in the water tank 100 is discharged through the first discharge hole 12, it can flow out along the protrusion 14, making it less likely for the discharged water to flow into the settling tank 13. This ensures that water does not easily adhere to the tank wall of the water tank 100 and also reduces water splashing. Furthermore, the protrusion 14 also protects the operating lever 221, making it less prone to breakage and extending its service life.

[0061] like Figure 8As shown, a portion of the end face of the sleeve 14 is provided with an extension section 15 extending outward along the axial direction of the sleeve 14. The second end of the operating lever 221 is provided with a flange 2216, which fits within the extension section 15 to guide the rotation of the operating lever 221. The two upper end faces of the extension section 15 constitute a limit on the rotation of the handle 2215, preventing the operating lever 221 from rotating excessively.

[0062] Specifically, there are two first discharge holes 12, with their central axes located on the same horizontal plane and symmetrically arranged about the central axis of the mounting hole 11. When the handle 2215 is rotated to the upper end face of the extension section 15 and contacts the upper end face of the extension section 15, the second discharge hole 211 on the sealing part 21 communicates with the first discharge hole 12, and the central axis of the second discharge hole 211 is collinear with the central axis of the first discharge hole 12. Thus, the extension section 15 not only limits the rotation range of the handle 2215 but also improves the accuracy of the communication between the first discharge hole 12 and the second discharge hole 211. In addition, the extension section 15 extends the flow path of the discharged water within the sleeve 14, further ensuring that the discharged water does not easily flow into the settling tank 13.

[0063] Optionally, such as Figure 1 and Figure 4 As shown, the water tank 100 also includes a heating element 3 and a base 4. The water tank 100 has a bottom wall 16 and a peripheral wall 17. The peripheral wall 17 includes an upper peripheral wall section 171 located above the bottom wall 16 and a lower peripheral wall section 172 located below the bottom wall 16. The heating element 3 is disposed on the bottom wall 16 of the water tank 100 and is used to heat the water in the water tank 100. The base 4 is connected to the lower end of the lower peripheral wall section 172. The base 4, the lower peripheral wall section 172, and the bottom wall 16 enclose a mechanical cavity 5.

[0064] Specifically, the upper and lower wall sections 171 and 172 can be integrally formed, ensuring the integrity of the outer circumference of the water tank 100 and improving its structural strength. The mounting hole 11 and the first discharge hole 12 are located at the lower end of the upper wall section 171. The bottom wall 16 separates the water tank 100 into a mechanical cavity 5, and the components on the base 4 are located within the mechanical cavity 5, improving the utilization of space in the water tank 100. The water tank 100 has a simple structure, saving manufacturing costs.

[0065] Optionally, such as Figure 11 As shown, the water tank 100 also includes a tank cover 6, which is used to cover the top of the tank body 1.

[0066] Specifically, the lid 6 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 6 has a water filling hole (not shown), and the lid 6 gradually curves downward from the outer periphery towards the center to facilitate the addition of water into the tank body 1. By setting the lid 6, water in the tank body 1 is less likely to overflow, ensuring the safety of the water tank 100 during use.

[0067] The humidifier according to an embodiment of the present invention is described below.

[0068] like Figure 11 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 located on the upper surface of the box cover 6, 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 6. The water in the box body 1 is atomized through the mist outlet pipe 7 and discharged from the mist outlet cap 8.

[0069] The humidifier of this utility model embodiment has a convenient and time-saving drainage system for the water tank 100, which makes drainage of the humidifier 200 convenient, time-saving, and labor-saving, thereby improving user satisfaction.
