The first cavity is used to store water. It also includes a water-sealing assembly. The water-proof wall has an installation port that penetrates its upper and lower surfaces. The water-sealing assembly includes a water-sealing cover, a float seal, and a float limiting member. The water-sealing cover is sealed to the installation port of the water-proof wall. The water-sealing cover has a water-sealing hole for connecting the first cavity and the second cavity. A float limiting member is provided on the side of the water-sealing cover away from the first cavity. The float limiting member is used to limit the movement space of the sealing end of the float seal.

This not only achieves water level regulation, but also has a simple structure and low cost.

Description

Technical Field

[0001] This utility model relates to the field of drainage sealing technology, and in particular to a drainage sealing mechanism and a humidifier. Background Technology

[0002] Humidifiers typically have a water tank and a water trough. The water trough contains an atomizing component that atomizes the water, while the water tank continuously supplies water to the trough to regulate the normal operating water level.

[0003] Most humidifiers on the market currently use the float lever principle or atmospheric pressure difference principle to regulate water level, but such structures are relatively complex and costly. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a water sealing mechanism and a humidifier that not only enables water level adjustment but also features a simple structure and low cost.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This utility model provides a drainage sealing mechanism, including a first cavity and a second cavity that are independent of each other. The first cavity and the second cavity are separated by a water-proof wall. The first cavity is used to store water. The drainage sealing assembly also includes a drainage sealing component. The water-proof wall has an installation port that penetrates its upper and lower surfaces. The drainage sealing component includes a drainage cover, a float seal, and a float limiting member. The drainage cover is sealed and fitted into the installation port of the water-proof wall. The drainage cover has a drainage hole for connecting the first cavity and the second cavity. A float limiting member is provided on the side of the drainage cover away from the first cavity. The float limiting member is used to limit the movement space of the sealing end of the float seal. When water is injected from the first cavity into the second cavity, the float seal floats up in the water in the second cavity due to its own buoyancy until the sealing end abuts against the drainage hole near the outer wall of the second cavity to block the drainage hole.

[0007] Furthermore, the float seal includes a float and a sealing gasket. The end of the float near the drain cover has an outwardly protruding portion, and the sealing gasket is disposed at the outward end of the protruding portion. The float limiting member has a hollow limiting cavity, and the limiting cavity has a clearance opening away from the bottom wall of the drain cover. The protruding portion is movably inserted into the limiting cavity, and the outer diameter of the protruding portion is larger than the inner diameter of the clearance opening. The protruding portion and the sealing gasket together constitute the sealing end.

[0008] Furthermore, the float is a float cylinder structure, and the float limiting member is an annular structure.

[0009] Furthermore, the outer peripheral wall of the drain cover is provided with a snap-fit ​​groove, and the inner peripheral wall of the float limiting member is provided with a snap-fit ​​portion that protrudes inward; the float limiting member is sleeved on one end of the drain cover near the second cavity, and the snap-fit ​​portion is detachably snapped into the snap-fit ​​groove.

[0010] Furthermore, the drain sealing assembly includes a filter element, and a removable filter element is provided on the side of the drain cover opposite to the second cavity.

[0011] Furthermore, the filter element includes a connecting part and a filter part disposed at one end of the connecting part. The drain cover is provided with a mounting groove for accommodating the connecting part. The outer peripheral surface of the connecting part has a plurality of protruding points spaced apart and protruding outward. The connecting part is detachably inserted into the mounting groove, and the protruding points abut against the inner wall of the mounting groove.

[0012] Furthermore, the filter section has a hollow filter cavity that is connected to the drain hole, and the wall of the filter cavity has multiple filter slots.

[0013] Furthermore, the filter section is in a straight line shape.

[0014] This utility model provides a humidifier, including a main body, a water tank, and the aforementioned water sealing mechanism; the main body includes a water trough and an atomizing component disposed within the water trough; the water trough and the water tank are arranged adjacent to each other at intervals; the inner cavity of the water tank is the first cavity; the inner cavity of the water trough is the second cavity.

[0015] The technical solution provided by this utility model has the following beneficial effects:

[0016] When water is injected into the second cavity from the first cavity, the float seal rises in the water in the second cavity by its own buoyancy, so that the sealing end of the float seal is pressed against the drain hole of the drain cover near the outer wall of the second cavity, thereby blocking the drain hole. In this way, the water level of the second cavity can be adjusted by itself, and the structure of the drain sealing mechanism is simple and low cost. Attached Figure Description

[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] Reference Figures 1 to 3 This embodiment provides a humidifier, including a main body 1, a water tank 2 and a water sealing mechanism 100. The main body 1 includes a water tank 11 and an atomizing component disposed in the water tank 11. The water tank 11 and the water tank 2 are arranged adjacent to each other and spaced apart. The inner cavity of the water tank 2 is defined as the first cavity 21 and the inner cavity of the water tank 11 is defined as the second cavity 111. At this time, the first cavity 21 and the second cavity 111 are separated by a common water-proof wall 3, and the water-proof wall 3 has an installation port 31 that penetrates its upper and lower surfaces.

[0023] like Figure 1 and Figure 2 As shown, the drain sealing mechanism 100 of this embodiment includes a first cavity 21, a second cavity 111, and a drain sealing assembly 4, wherein, as Figure 3 The shown drain sealing assembly 4 includes a drain cover 41, a float seal 42, and a float limiter 43.

[0024] The drain cover 41 is installed in the mounting port 31 of the water-proof wall 3 through a sealing ring structure to achieve a sealed fit. The center of the drain cover 41 has a drain hole 411 for connecting the first cavity 21 and the second cavity 111.

[0025] A float limiting member 43 is provided on the bottom side of the drain cover 41 away from the first cavity 21. The float limiting member 43 is used to limit the movement space of the sealing end 44 of the float seal 42.

[0026] When water is injected into the second cavity 111 from the first cavity 21, the water level in the second cavity 111 gradually increases. The float seal 42 floats up in the water in the second cavity 111 due to its own buoyancy until the sealing end 44 abuts against the drain hole 411 and approaches the outer wall of the second cavity 111 to block the drain hole 411. At this time, the water level in the water tank 11 reaches the normal working range, and the water tank 2 no longer continues to add water to the water tank 11.

[0027] When the water level in the second cavity 111 is too low, the float seal 42 also gradually moves downward away from the drain hole 411 located above it as the water level in the second cavity 111 decreases. At this time, the drain hole 411 connects the first cavity 21 and the second cavity 111 again, so that the water in the water tank 2 can flow into the water tank 11 through the drain hole 411 to complete the timely replenishment of water in the water tank 11.

[0028] In this embodiment, as Figure 2 and Figure 3 As shown, the float seal 42 includes a float 421 and a sealing gasket 422. Specifically, the float 421 is a float cylinder structure, the float limiting member 43 is an annular structure, and the sealing gasket 422 is a circular sealing silicone gasket. Of course, in other embodiments, the structures of the float 421, the float limiting member 43, and the sealing gasket 422 are not limited to this, and will not be described in detail here.

[0029] The float 421 has an outwardly extending protrusion 423 at its upper end near the drain cover 41. A sealing gasket 422 is provided inside the upper end of the protrusion 423. At this time, the protrusion 423 and the sealing gasket 422 together constitute the sealing end 44.

[0030] The float limiting member 43 has a hollow limiting cavity 431. The limiting cavity 431 is provided with a clearance opening 432 away from the bottom wall of the drain cover 41. The protrusion 423 is movably inserted into the limiting cavity 431. Other parts of the float 421 can movably pass through the clearance opening 432 to ensure that the float 421 can move up and down in the limiting cavity 431 under the action of buoyancy in the water, so as to move away from or close to the drain hole 411.

[0031] More specifically, the outer diameter of the protrusion 423 is larger than the inner diameter of the relief opening 432, so that the outer peripheral wall of the relief opening 432 forms a limiting wall 433 to prevent the float seal 42 from moving away from the float limiter 43. This ensures that the sealing end 44 of the float seal 42 has only a certain amount of room to move under the restriction of the float limiter 43, and forms an integral connection structure.

[0032] When water is injected into the second cavity 111 from the first cavity 21, the float seal 42 floats up in the water in the second cavity 111 by its own buoyancy, so that the sealing end 44 of the float seal 42 pushes against the drain hole 411 of the drain cover 41 close to the outer wall of the second cavity 111, thereby blocking the drain hole 411. In this way, the water level of the second cavity 111 can be adjusted by itself, and the drain sealing mechanism 100 has a simple structure and low cost.

[0033] Of course, in other embodiments, the application scope of the drain sealing mechanism 100 is not limited to humidifiers, but can also be applied to the drain sealing between two adjacent water storage cavities.

[0034] Further preferred, such as Figure 3 As shown, the outer peripheral wall of the drain cover 41 is provided with a snap-fit ​​groove 412, and the inner peripheral wall of the float limiting member 43 is provided with a snap-fit ​​part 434 that protrudes inward. When the float limiting member 43 is sleeved on the lower end of the drain cover 41 near the second cavity 111, the snap-fit ​​part 434 can be detachably snapped into the snap-fit ​​groove 412. In this way, the float limiting member 43 can be quickly and conveniently detachably assembled onto the drain cover 41.

[0035] Further preferred, such as Figure 3 As shown, the drain sealing assembly 4 also includes a filter element 5, and a removable filter element 5 is provided on the upper side of the drain cover 41 away from the second cavity 111.

[0036] In this specific embodiment, such as Figure 2 and Figure 3 As shown, the filter element 5 includes a connecting part 51 and a filter part 52 disposed on the upper end of the connecting part 51. The drain cover 41 is provided with a mounting groove 413 for accommodating the connecting part 51. The outer peripheral surface of the connecting part 51 has a plurality of protruding dots 511 spaced apart and protruding outward.

[0037] When the connecting part 51 is detachably inserted into the mounting groove 413, the protrusion 511 abuts against the inner wall of the mounting groove 413 to restrict the filter element 5 on the drain cover 41, and also facilitates the removal and cleaning of the filter element 5.

[0038] Furthermore, the filter section 52 is in the shape of a straight line and has a hollow filter cavity 521. The filter cavity 521 is connected to the drain hole 411. The wall of the filter cavity 521 has multiple filter slots 522 that penetrate its inner and outer surfaces to filter foreign objects mixed in the water tank 2.

[0039] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
