[0028] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure. Therefore, the drawings and description are to be considered as illustrative in nature and not restrictive.

[0029] In the related art, a kettle or heating atomizer typically includes a base, a pot body, and a lid. The base primarily provides power and control. The pot body serves as a container, and also has a heating element to heat the water inside. The lid primarily cooperates with the pot body to form a relatively sealed space, preventing the water inside from being easily poured out. The lid is designed with a steam hole. In an electric kettle, the steam hole primarily prevents the water inside the container from spraying out of the spout when heated. In an atomizer, the steam hole can also be used to spray water vapor, thereby controlling the indoor humidity.

[0030] When a kettle or atomizer of the related art is accidentally tipped over, a large amount of water (more than 50 ml per second) will flow out of the container.

[0031] In order to solve the problem of a large amount of water flowing out of the cover assembly when the device falls over in the related art, an embodiment of the present disclosure provides a cover assembly, and the cover assembly of the embodiment of the present disclosure is described in detail with reference to the accompanying drawings.

[0032] Reference Figure 1 and Figure 2 As a first aspect of an embodiment of the present disclosure, an embodiment of the present disclosure provides a cover assembly 1, comprising a shell 10, a piston 20 and a switch portion 30. A steam outlet 11 is formed through the shell 10. The piston 20 comprises a vertical portion 21 and a flange portion 22 protruding from the circumference of the vertical portion 21, and the vertical portion 21 is adapted to the steam outlet 11. The switch portion 30 is used to control the piston 20 to open or close the steam outlet 11. When the cover assembly 1 is in a normal state, the switch portion 30 controls the vertical portion 21 to be located in the steam outlet 11, so that the flange portion 22 is away from the inner side of the shell 10 to open the steam outlet 11. When the cover assembly 1 is in a tilted state, the switch portion 30 controls the vertical portion to reset and extend to the steam outlet 11, so that the flange portion 22 is in contact with the inner side of the shell 10 to block the steam outlet 11.

[0033] Exemplarily, a steam outlet 11 is formed through the housing 10 . When the steam outlet 11 is not blocked, steam can flow out from the steam outlet 11 .

[0034] The vertical portion 21 is adapted to the steam outlet 11, and its dimensions are adapted to the dimensions of the steam outlet 11. For example, the diameter of the vertical portion 21 is substantially equal to the diameter of the steam outlet 11. The flange portion 22 is disposed around the circumference of the vertical portion 21, and the specific dimensions of the flange portion 22 are not limited herein.

[0035] The switch portion 30 is used to control the piston 20 to open or close the steam outlet 11. In the related art, since there is no switch portion 30, when the device tilts and overturns, the liquid in the device can flow out through the steam outlet 11. In the embodiment of the present disclosure, when the cover assembly 1 is in a normal state, that is, the device is working normally and has not overturned or tilted, the switch portion 30 controls the vertical portion 21 to be located in the steam outlet 11, so that the flange portion 22 is away from the inner side of the shell 10 to open the steam outlet 11, so that steam can go out of the steam outlet 11. When the cover assembly 1 is in a tilted state, the switch portion 30 controls the vertical portion 21 to reset and extend to the steam outlet 11, so that the flange portion 22 fits with the inner side of the shell 10 to block the steam outlet 11, thereby preventing liquid from flowing out of the steam outlet, thereby improving the safety of the device.

[0036] In the cover assembly of the disclosed embodiment, the steam outlet 11 is provided on the shell 10. The vertical portion 21 of the piston 20 is adapted to the steam outlet 11.

When the cover assembly 1 is in a normal state, the switch portion 30 controls the vertical portion 21 to be located inside the steam outlet 11, so that the flange portion 22 is away from the inner side of the shell 10 to open the steam outlet 11. When the cover assembly 1 is in a tilted state, the switch portion 30 controls the vertical portion to be reset and extended to the steam outlet 11, so that the flange portion 22 is fitted with the inner side of the shell 10 to block the steam outlet 11. With such a setting, when the device is overturned and tilted, liquid can be prevented from flowing out of the steam outlet 11, thereby improving the safety of the device.

[0037] Reference Figure 1 and Figure 2 In a disclosed embodiment, the shell 10 includes a lower shell 12 and an upper shell 13. The lower shell 12 and the upper shell 13 are detachably installed.

[0045] Exemplarily, the sealing ring 40 is disposed on a side of the first main body 132 proximal to the body of the liquid heating device. The sealing ring 40 is secured to the lower housing 13 via a second fastener. For example, the first main body 132 of the lower housing 13 may have a bolt hole formed therein, and the second fastener passes through the sealing ring 40 and is threadedly secured to the bolt hole.

[0046] Reference Figure 1 and Figure 2 In a disclosed embodiment, the cover assembly 1 further includes a spherical sliding body 50. The sliding body 50 is located outside the upper shell 12 and is movably arranged. The sliding body 50 forms the switch portion 30. When the cover assembly 1 is in a normal state, the sliding body 50 is pressed against the top of the vertical portion 21, so that the flange portion 22 is positioned away from the steam outlet 11, thereby opening the steam outlet 11 to allow steam to flow out. When the cover assembly 1 is in a tilted state, the sliding body 50 slides out of contact with the vertical portion 21, and the flange portion 22 is close to the inner side of the shell 10, so that the steam outlet 11 is blocked by the flange portion 22 to prevent water from flowing out.

[0047] For example, the middle portion of the upper housing 12 is tapered and tilted, with the piston positioned at the bottom of the tapered structure. The sliding body 50 is spherical. When the cover assembly 1 is in a normal state, the sliding body 50 is pressed against the top of the vertical portion 21. When the cover assembly is tilted, the sliding body 50 slides away from the vertical portion 21, thereby returning the vertical portion 21 to its original position and allowing the flange portion 22 to mate with the inner side of the housing 10.

[0048] Reference Figure 1 and Figure 2 In one disclosed embodiment, the cover assembly 1 further includes a deflector cover 60, which is positioned over the slider 50.
