Description

Technical Field

[0001] This invention relates to the field of humidifier technology, and particularly to a top-fill humidifier water tank and a top-fill humidifier. Background Technology

[0002] Humidifiers are divided into top-fill humidifiers and bottom-fill humidifiers. Top-fill humidifiers, with their convenient water filling feature, are popular among consumers. Existing top-fill humidifiers typically include a water tank and a base with an atomizing chamber. The bottom of the water tank connects to the atomizing chamber via a water outlet, and a water valve and a water replenishment control mechanism are located at the outlet. When the water level in the atomizing chamber drops to a predetermined height, the water replenishment control mechanism pushes the water valve upwards, allowing water from the tank to flow into the atomizing chamber. When the water level in the atomizing chamber rises to the predetermined height, the water valve resets, and its sealing disc blocks the outlet, preventing further water from flowing into the atomizing chamber and causing the water level to become too high.

[0003] However, with prolonged use, scale can easily accumulate at the bottom of the water tank. The presence of scale can prevent the water outlet from being completely sealed between the sealing plate and the water tank (see [link]). Figure 14 When the water tank is not properly sealed, the water inside will continue to flow into the atomizing chamber under its own weight, causing water to overflow between the water tank and the base.

[0004] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a water tank and a top-fill humidifier, which aims to solve the problem of easy water overflow between the water tank and the base of the existing top-fill humidifier.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A top-fill humidifier water tank includes a water tank body with a water outlet at the bottom, a mist outlet vertically disposed within the water tank body, and a water valve assembly disposed within the water outlet. The upper end of the mist outlet is connected to the top of the water tank body. A water inlet is provided on the top of the water tank body, and a sealing cap is detachably provided on the water inlet. A closed space is formed between the outer wall of the mist outlet and the water tank body.

[0008] In the water tank of the top-fill humidifier, the sealing cover includes a first cover plate and a first annular wall; the first annular wall is located at the bottom of the first cover plate and extends downward through the water inlet; the shape of the water inlet is adapted to the shape of the first annular wall.

[0009] In the water tank of the top-filled humidifier, the sealing cover further includes a plurality of protrusions horizontally disposed on the outer side of the first ring wall; the protrusions are circumferentially equidistantly distributed on the outer side of the first ring wall; a convex ring is provided on the inner side of the top of the water tank body around the water inlet downward; the inner side of the convex ring is provided with grooves of the same number as the protrusions, and the grooves are circumferentially equidistantly distributed on the inner side of the convex ring.

[0010] In the water tank of the top-filled humidifier, a positioning block is provided at the bottom of the convex ring, and the positioning block is located next to the groove.

[0011] In the water tank of the top-filled humidifier, a sealing ring is fitted on the first annular wall.

[0012] In the water tank of the top-filled humidifier, the sealing cover includes a second cover plate and a second annular wall located at the bottom of the second cover plate; the top of the water tank body is provided with an annular surrounding plate around the water inlet, and the second annular wall is threadedly connected to the outer side of the annular surrounding plate.

[0013] The water tank of the top-fill humidifier also includes an outer cover covering the upper part of the water tank body; the outer cover includes an outer cover body, a mist outlet cover on the outer cover body, a mist outlet top cover on the mist outlet cover, and a mist guide cover located at the bottom of the outer cover body and below the mist outlet cover; the mist outlet top cover has a mist outlet; the lower part of the mist guide cover is located at the top of the water tank body, and the mist guide cover is connected to the mist outlet cylinder.

[0014] In the water tank of the top-filled humidifier, a positioning cylinder is provided on the top of the water tank body. The positioning cylinder contacts the inner wall of the mist guide hood and is used to position the mist guide hood.

[0015] The present invention also provides a top-fill humidifier, comprising a base with an atomizing chamber, an atomizer disposed at the bottom of the atomizing chamber, a liquid level switch disposed within the atomizing chamber, a water replenishment control mechanism disposed within the atomizing chamber, and a fan disposed at the bottom of the atomizing chamber; it also includes the aforementioned top-fill humidifier water tank, which is detachably mounted on the base; the fan is used to supply air to the mist outlet, the atomizer is located below the mist outlet, and the water replenishment control mechanism is used to lift the water valve assembly.

[0016] In the aforementioned top-fill humidifier, a partition is vertically installed inside the atomizing chamber, which divides the atomizing chamber into two interconnected chambers.

[0017] Beneficial effects:

[0018] This invention provides a top-fill humidifier water tank and a top-fill humidifier. The top-fill humidifier includes a water tank and a base. By setting a sealing cap on the water inlet of the water tank body, a closed space is formed between the outer wall of the mist outlet and the water tank body. After water is added to the water tank body, the interior of the water tank body above the water surface is in a sealed environment. The air pressure in this sealed environment decreases as water flows into the atomization chamber, making the air pressure inside the water tank body lower than the external atmospheric pressure and the air pressure above the water surface in the atomization chamber. Even when the water level in the atomization chamber rises to a predetermined height, the water valve assembly cannot completely block the water outlet. Under the pressure difference between the inside and outside of the water tank body, the water inside the water tank body will not flow into the atomization chamber under its own gravity. This solves the problem of easy water overflow between the water tank and the base in existing top-fill humidifiers due to poor water tank sealing. Attached Figure Description

[0044] This invention provides a top-fill humidifier water tank and a top-fill humidifier. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

Furthermore, some of the aforementioned terms may have other meanings besides indicating orientation or positional relationship; for example, the term "upper" may in some cases indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this invention according to the specific circumstances.

[0046] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0047] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0048] like Figure 5 , Figure 7 as well as Figure 1 As shown, the present invention provides a top-fill humidifier water tank, which is placed on the base 7 of the top-fill humidifier during use and when adding water. The top-fill humidifier water tank includes a water tank body 1 with a water outlet 101 at the bottom, a mist outlet 2 vertically disposed inside the water tank body 1, and a water valve assembly 4 disposed inside the water outlet 101; the upper end of the mist outlet 2 is connected to the top of the water tank body 1, and is used to guide the water mist in the atomization chamber 71 of the base 7 out of the top-fill humidifier; the top of the water tank body 1 has a water inlet 102, and a detachable sealing cap 3 is provided on the water inlet 102, and a closed space is formed between the outer wall of the mist outlet 2 and the water tank body 1.

[0049] Among them, the water valve assembly 4 can be the water valve structure commonly used in the water tank of existing top-filled humidifiers.

[0050] This invention, by providing a sealing cap 3 on the water inlet 102 of the water tank body 1, creates a closed space between the outer wall of the mist outlet 2 and the water tank body 1. After water is added to the water tank body 1, the interior of the water tank body 1 above the water surface is in a sealed environment. The air pressure in this sealed environment decreases as water flows into the atomizing chamber 71, making the air pressure inside the water tank body 1 lower than the external atmospheric pressure and the air pressure above the water surface in the atomizing chamber 71. Even when the water level in the atomizing chamber 71 rises to a predetermined height, the water valve assembly 4 cannot completely block the water outlet 101. Under the pressure difference between the inside and outside of the water tank body 1, the water inside the water tank body 1 will not flow into the atomizing chamber 71 under its own gravity. This solves the problem of easy water overflow between the water tank and the base 7 in existing top-fill humidifiers due to poor water tank sealing.

[0051] like Figure 5 , Figure 6 and Figure 8 As shown, in one embodiment, the water valve assembly 4 may also include the following structure: a pressure rod 401, a force-receiving plate 402 disposed at the bottom of the pressure rod 401, a sealing plate 403 disposed at the top of the pressure rod 401, a tray 404 fixedly covering the water outlet 101 (the tray 404 is located on the inner bottom of the water tank body 1), and a spring 405 sleeved on the pressure rod 401. The top of the pressure rod 401 extends into the water tank body 1 through the water outlet 101, allowing the pressure rod 401, which has a sealing plate 403 on top, to be supported by the tray 404. When the pressure rod 401 is supported by the tray 404, the sealing plate 403 can block the tray 404, so that water in the water tank body 1 will not enter the water outlet 101 through the opening on the tray 404. When it is necessary to replenish water to the atomizing chamber 71, the pressure rod 401 will be lifted by the water replenishment control mechanism 10, causing the sealing plate 403 to separate from the tray 404, so that water in the water tank body 1 can enter the water outlet 101 through the tray 404 and then flow into the atomizing chamber 71 of the base 7.

[0052] In the above embodiment, the outlet 101 of the water tank body 1 is not directly blocked by the sealing disc 403. Instead, a conical tray 404 is used to fix and cover the outlet 101. The conical sealing disc 403 blocks the tray 404 so that the water in the water tank body 1 will not flow into the outlet 101. In this way, even if scale is deposited in the water tank body 1, the scale will not affect the sealing performance of the sealing disc 403 on the upper part of the tray 404, so that the water in the water tank body 1 flows into the atomizing chamber 71 when no water replenishment is needed.

[0053] Furthermore, the two ends of the spring 405 are respectively connected to the upper part of the force-receiving plate 402 and the bottom of the sealing plate 403. When the pressure rod 401 is pushed upward, the spring 405 is in a compressed state. When the water level in the atomizer 8 chamber reaches the preset height, the water replenishment control mechanism 10 no longer pushes the pressure rod 401. The spring 405 can reset and pull the pressure rod 401 downward, so that the sealing plate 403 can seal the tray 404 again, and the water in the water tank body 1 will not flow into the atomizing chamber 71.

[0054] like Figure 9 and Figure 10 As shown, in one embodiment, the sealing cap 3 includes a first cover plate 311 and a first annular wall 312; the first annular wall 312 is disposed at the bottom of the first cover plate 311, and the shape of the water inlet 102 is adapted to the shape of the first annular wall 312. By designing the sealing cap 3 as a structure composed of the first cover plate 311 and the first annular wall 312, the sealing cap 3 is easy to remove and place. When it is necessary to place the sealing cap 3 on the water inlet 102, the first annular wall 312 passes downward through the water inlet 102, while the first cover plate 311 is supported by the top of the water tank body 1 and will not fall into the water tank body 1.

[0055] Furthermore, the sealing cover 3 also includes a plurality of protrusions 313 horizontally disposed on the outer side of the first annular wall 312; the protrusions 313 are circumferentially and equidistantly distributed on the outer side of the first annular wall 312; a protruding ring 103 is provided on the inner side of the top of the water tank body 1 around the water inlet downward; after the first annular wall 312 passes downward through the water inlet 102, the lower part of the protrusions 313 and the protruding ring 103 can be kept in a snap-fit ​​state, so that the sealing cover 3 will not loosen after being placed on the water inlet 102, and the interior of the water tank body 1 can maintain good sealing performance.

[0056] The inner side of the convex ring 103 has grooves 1031 in the same number as the protrusions 313, and the grooves 1031 are circumferentially and evenly distributed on the inner side of the convex ring 103. When it is necessary to remove the sealing cap 3 from the water tank body 1, the user can rotate the sealing cap 3, so that the protrusions 313, which are in a snap-fit ​​state with the convex ring 103, rotate to the bottom of the grooves 1031. The grooves 1031 are designed so that when the user lifts the sealing cap 3 upwards, the protrusions 313 can pass through the top of the water tank body 1, thus ensuring that the sealing cap 3 can be easily removed from the water tank body 1. Preferably, in order to facilitate the user to rotate the sealing cap 3, the upper part of the first cover plate 311 is provided with a hand-held handle 314.

[0057] Furthermore, a positioning block 104 is provided at the bottom of the protruding ring 103; the positioning block 104 is located next to the groove 1031 and is used to position the protrusion 313. When the protrusion 313 is rotated to the bottom of the groove 1031, the positioning block 104 can block the protrusion 313, thereby reminding the user that there is no need to rotate the sealing cover 3.

[0058] Furthermore, a sealing ring 315 is fitted onto the first annular wall 312. The sealing ring 315 is an elastic sealing ring 315, which can improve the sealing performance of the sealing cover 3; in addition, when the sealing cover 3 is placed on the water inlet, the annular sealing ring 315 and the annular first annular wall 312 are in a state of mutual compression, so the sealing cover 3 will not loosen.

[0059] like Figure 11 As shown, the present invention also provides another structural form of the sealing cover 3. Specifically, the sealing cover 3 includes a second cover plate 321 and a second annular wall 322 disposed at the bottom of the second cover plate 321. The inner side of the second annular wall 322 is provided with an internal thread (not shown in the figure). When the sealing cover 3 adopts this structural form, the top of the water tank body 1 is provided with an annular surrounding plate 5 around the water inlet 102, and the second annular wall 322 can be threadedly connected to the outer side of the annular surrounding plate 5. This not only makes it easier to put on and take off the sealing cover 3, but also does not reduce the sealing performance of the sealing cover 3.

[0060] like Figures 1 to 4 As shown, in one embodiment, the water tank of the top-filled humidifier further includes an outer cover 6 covering the upper part of the water tank body 1; the outer cover 6 includes an outer cover body 61, a mist outlet cover 62 rotatably disposed on the outer cover body 61, a mist outlet upper cover 63 disposed on the mist outlet cover 62, and a mist guide hood 64 that can be fastened to the bottom of the outer cover body 61 and located below the mist outlet cover 62; the mist outlet upper cover 63 is provided with a mist outlet 631; the lower part of the mist guide hood 64 is placed on the top of the water tank body 1, and the mist guide hood 64 is connected to the mist outlet cylinder 2. In this embodiment, by covering the water tank body 1 with an outer cover 6, the internal sealing of the water tank body 1 can be improved. In addition, a mist guide 64 is provided between the outer cover body 61 and the top of the water tank body 1. When the mist outlet 2 emits mist upward, the water mist can only be guided to the mist outlet cover 62 through the mist guide 64. Therefore, no water mist will appear outside the mist guide 64. This not only prevents water from remaining on the top of the water tank body 1, but also prevents water mist from entering the water tank body 1 through the water inlet and thus reducing the internal sealing of the water tank body 1 when the sealing performance of the sealing cover 3 is poor.

[0061] like Figure 2As shown, in one embodiment, the top of the water tank body 1 is provided with a positioning cylinder 105. When the outer cover 6 is placed on the upper part of the water tank body 1, the positioning cylinder 105 is inserted into the mist guide 64 and contacts the inner wall of the mist guide 64. Therefore, the positioning cylinder 105 can play a positioning role for the mist guide 64. Thus, during the installation of the outer cover 6, the positioning of the mist guide 64 by the positioning cylinder 105 can be used to quickly install the outer cover 6.

[0062] like Figure 1 , Figure 12 and Figure 13 As shown, the present invention also provides a top-fill humidifier, including a base 7 with an atomizing chamber 71, an atomizer 8 disposed at the bottom of the atomizing chamber 71, a liquid level switch 9 disposed in the atomizing chamber 71, a water replenishment control mechanism 10 disposed in the atomizing chamber 71, and a fan 11 disposed at the bottom of the atomizing chamber 71; it also includes the above-mentioned top-fill humidifier water tank, which is detachably disposed on the base 7; the atomizing chamber 71 of the base 7 is provided with an air outlet pipe 72 located below the mist outlet cylinder 2, and the air inlet of the air outlet pipe 72 is located above the fan 11.

[0063] The fan 11 is used to supply air to the mist outlet 2; the atomizer 8 can be an atomizing plate and is located below the mist outlet 2; the water replenishment control mechanism 10 is a dynamic balance lever, which can swing and lift the water valve assembly 4 when the water level in the atomizing chamber 71 is low, so that the water in the water tank body 1 flows into the atomizing chamber 71; the liquid level switch 9 can be a float liquid level switch and is electrically connected to the controller 12. When the water level in the atomizing chamber 71 is too low and triggers the float liquid level switch 9, the controller 12 will receive an electrical signal from the float liquid level switch to shut off the atomizer 8, so that after the water in the atomizing chamber 71 has completely evaporated, the situation of the atomizer 8 still generating heat and the upper water humidifier burning out and being damaged can be avoided.

[0064] In the top-fill humidifier provided by the present invention, since the water tank body 1 has good sealing performance, there will be no water overflow between the water tank body 1 and the base 7 when the top-fill humidifier is working for a long time.

[0065] When water needs to be added to the atomizing chamber 71, the water valve assembly 4 is lifted by the water replenishment control mechanism 10. After the water valve assembly 4 is lifted, the water vapor (generated by the fan) in the atomizing chamber 71 will enter the water tank body 1 through the water outlet, which will increase the air pressure above the water surface in the water tank body 1. When the air pressure above the water surface in the water tank body 1 increases to the same level as the air pressure above the water surface in the atomizing chamber 71, the water in the water tank body 1 can flow into the atomizing chamber 71 under its own gravity, thereby replenishing the atomizing chamber 71 with water. When the water level in the atomizing chamber 71 rises, the water in the atomizing chamber 71 will rush into the conduit 106 below the outlet, making it impossible for the atomizing chamber 7 to communicate with the inside of the water tank body 1. As the water level in the atomizing chamber 71 continues to rise, the air pressure above the water surface in the water tank body 1 gradually decreases, and the airflow generated by the fan cannot enter the water tank body 1. When the air pressure above the water surface in the water tank body 1 is less than the air pressure above the water surface in the atomizing chamber 71, the water in the water tank body 1 cannot flow into the atomizing chamber 71.

[0066] like Figure 12 As shown, in one embodiment, a partition 73 is vertically provided inside the atomizing chamber 71, which divides the atomizing chamber 71 into two interconnected chambers. The partition 73 prevents the water in the atomizing chamber 71 from fluctuating frequently when the top-filled humidifier is working, thereby ensuring the accuracy of water level detection.

[0067] like Figure 13 As shown, in one embodiment, a baffle 74 is provided around the fan 11 on the outer bottom of the atomizing chamber 71. When the top-fill humidifier is working, if water and water mist in the atomizing chamber 71 enter the base 7 below the atomizing chamber 71 through the air outlet 72, the baffle 74 can prevent water from splashing onto other electronic components (such as the controller 12) outside the baffle 74, thereby protecting the electronic components inside the base 7 from getting wet and extending the service life of the electronic components. In addition, the bottom of the base 7 is provided with multiple drain holes 75, so that when water enters the base 7 below the atomizing chamber 71, the water can be quickly discharged through the drain holes 75.

[0068] In summary, this invention provides a top-fill humidifier water tank and a top-fill humidifier. The top-fill humidifier includes a water tank and a base. By setting a sealing cap on the water inlet of the water tank body, a closed space is formed between the outer wall of the mist outlet and the water tank body. After water is added to the water tank body, the interior of the water tank body above the water surface is in a sealed environment. The air pressure in this sealed environment decreases as the water flows into the atomization chamber, making the air pressure inside the water tank body lower than the external atmospheric pressure and the air pressure above the water surface in the atomization chamber. Even when the water level in the atomization chamber rises to a predetermined height, the water valve assembly cannot completely block the water outlet. Under the condition of a pressure difference between the inside and outside of the water tank body, the water inside the water tank body will not flow into the atomization chamber under its own gravity, thereby solving the problem of easy water overflow between the water tank and the base of existing top-fill humidifiers.
