In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

In the present invention, as shown in fig. 1, an electric hot water bottle is provided, which comprises a bottle body 1, an inner container (not shown in the figure) arranged on the bottle body 1, a water pump 2, and a water outlet pipe 3, wherein the water outlet pipe 3 is communicated with the inner container and the water pump 2, one end of the water outlet pipe 3 far away from the inner container is provided with a drainage pipe body 31, the lower end of the drainage pipe body 31 is opened, the drainage pipe body 31 is provided with an expanding section 311, the inner radial dimension of the upper side part of the expanding section 311 of the water outlet pipe 3 is smaller than the inner radial dimension of the expanding section 311, and the upper edge of the expanding section 311 is higher than the rated highest water level M of the inner container.

In the electric hot water bottle shown in fig. 1 and 2, the drain pipe body 31 has the diameter-expanding section 311, the upper edge of the diameter-expanding section 311 is higher than the rated highest water level M of the inner container, when the water pump 2 stops working, water at the diameter-expanding section 311 and below flows out into the water receiving container, most of the water flow above the upper edge of the diameter-expanding section 311 flows back to the inner container because the water flow is higher than the rated highest water level M in the inner container, a part of the water flow cannot flow back due to gravity, and the existence of the diameter-expanding section 311 in the drain pipe body 31 makes the part of the water flow not fill the diameter-expanding section 311, at this time, air enters the diameter-expanding section 311 from the lower opening of the drain pipe body 31 and counteracts the gravity of the part of the water flow, so that the part of the water flow is prevented from dropping, and the siphon effect is achieved.

In practical use, for example, when the water receiving object is mainly a child, or when the appearance and structure of the electric hot water bottle are required, the height of the water outlet of the electric hot water bottle needs to be reduced, the electric hot water bottle can be closer to a container for receiving water after the height position of the water outlet is reduced, the splashing of hot water is reduced, and the risk of scalding a user is reduced.

Compared with the existing electric thermos bottle with an anti-siphon channel and a one-way valve, the structure of the water outlet pipe 3 of the electric thermos bottle is simpler and has lower manufacturing cost.

In addition, in the utility model, no other pipeline deviates from the water outlet path of the water outlet pipe and extends, so that the appearance of the water outlet pipe 3 can be improved, and the overall visual aesthetic property of the electric hot water bottle is improved.

With regard to the structure of the drain pipe body 31, in a preferred embodiment, the middle or upper portion of the drain pipe body 31 is expanded to form the expanded diameter section 311. As shown in fig. 4 and 5, both the upper part of the drainage pipe 31 is expanded to form the expanded diameter section 311, and in an unillustrated implementation, the middle part of the drainage pipe 31 may be expanded to form the expanded diameter section 311, so long as the upper edge of the expanded diameter section is higher than the rated highest water level M.

In an alternative embodiment, as shown in fig. 2 and fig. 6, the lower edge of the expanded diameter section 311 extends to the opening of the drain pipe body 31, and the inner radial dimension of the expanded diameter section 311 gradually decreases from top to bottom, so that air can enter the drain pipe body 31 more easily and quantitatively, and gravity generated by more water flows can be offset, and the anti-siphon effect is further improved. Of course, as a changeable implementation manner in the present embodiment, as shown in fig. 3, the inner radial dimension of the expanding section 311 may be set to be uniform from top to bottom.

The shape of the expanded diameter section 311 formed by partially expanding the drain pipe body 31 is not limited to the circular shape shown in fig. 4 and 5, and may be an appropriate shape such as a prism shape or a rectangular shape, and it is only necessary to perform the function of expanding the diameter, and the upper edge of the expanded diameter section 311 is located above the rated maximum water level M.

Regarding the connection relationship of the drain pipe body 31 on the outlet pipe 3, in a preferred embodiment, the drain pipe body 31 is integrally provided on the outlet pipe 3. Both the drainage pipe body 31 partially expanded to form the expanded diameter section 311 shown in fig. 4 and the drainage pipe body 31 extending from the lower edge of the expanded diameter section 311 shown in fig. 3 to the opening can be integrally arranged with the outlet pipe 3, so that the integral arrangement simplifies the processing of the outlet pipe 3, simplifies the installation procedure of the outlet pipe 3, and reduces the subsequent connection fastening and sealing problems of the drainage pipe body 31 on the outlet pipe 3, thereby being beneficial to reducing the production cost.

In an alternative embodiment, the outlet pipe 3 further comprises a main pipe 32 connected to the inner container, and the main pipe 32 is detachably connected to the drainage pipe 31. As shown in fig. 1 and 5, the drain pipe body 31 having the diameter-enlarged section 311 formed by partially enlarging the drain pipe body or the drain pipe body 31 having the lower edge of the diameter-enlarged section 311 extending to the opening may be detachably connected to the outlet pipe 3. Because the bottle neck of the electric thermos bottle is the position which is most easily damaged by external impact, the drainage pipe body 31 and the main pipe body 32 are detachably connected, so that the damaged drainage pipe body 31 can be independently replaced without replacing the whole outlet pipe 3, and the maintenance cost is reduced.

The structure of the water outlet pipe 3 is further optimized in that, as shown in fig. 6, the inner diameter of the water outlet pipe 3 at the upper side part of the diameter-expanded section 311 is gradually reduced from top to bottom. In this way, when the water pump 2 is operated, the water flow can flow downward in a funnel shape on the upper side of the diameter expansion section 311, which is beneficial to gathering the water flow. Further, the upper edge of the diameter-increasing section 311 can be made smaller than the inner diameter of the lower side of the diameter-increasing section 311, thereby improving the anti-siphon effect.

When the main pipe 32 is detachably connected to the drain pipe 31, in a preferred embodiment, as shown in fig. 2, 5 and 6, the outlet pipe 3 further includes an extension pipe 33 integrally connected to the drain pipe 31, the extension pipe 33 is inserted into the main pipe 32, and an inner diameter of the extension pipe 33 is gradually reduced from top to bottom.

In the embodiment, as shown in fig. 6, it is further optimized that the main pipe body 32 is connected to the drain pipe body 31 in an interference fit manner and an anti-dropping barb 331 is formed along the outer circumference of the extension pipe body 33, so as to improve the connection reliability and sealing performance of the main pipe body 32 and the drain pipe body 31 at the connection position, and prevent the drain pipe body 31 from dropping off from the main pipe body 32 or the side water leakage phenomenon of the outlet pipe 3 from occurring.

In an alternative embodiment, the inner diameter of the main tube 32 at the upper portion of the expanding section 311 is gradually reduced from top to bottom. When the main tube 32 and the epitaxial tube 33 are detachably connected, the main tube 32 can be inserted into the epitaxial tube 33, so that the water flows down in a funnel-like manner at the end of the main tube 32. It should be noted that, when the drainage pipe 31 is integrally disposed on the outlet pipe 3, the main pipe 32 is equivalent to the pipe portion of the outlet pipe 3 located on the upper side of the drainage pipe 31, and at this time, the main pipe 32 can still achieve the effect of gradually reducing the inner diameter from top to bottom by increasing the wall thickness of the pipe from top to bottom.

In the embodiment shown in fig. 1, it is further preferable that, as shown in fig. 6, an extension rib 34 extending into the diameter-expanded section 311 is formed on an inner edge of an upper portion of the diameter-expanded section 311 of the water outlet pipe 3, and an outer diameter of the extension rib 34 is smaller than an inner diameter of the diameter-expanded section 311. The extending ribs 34 can guide the water flowing down from the upper edge of the diameter expanding section 311, so that the water flows with a certain length, the water is prevented from flowing to the inner wall of the diameter expanding section 311, the water can be prevented from being scattered, the water splashing is reduced, and the user experience is improved.

In the present embodiment, the formation manner of the extending bead 34 is not particularly limited. In a preferred embodiment, as shown in fig. 6, when the main pipe body 32 is detachably connected to the drain pipe body 31, the outlet pipe 3 further includes an extension pipe body 33 integrally connected to the drain pipe body 31, the extension pipe body 33 is inserted into the main pipe body 32, and a lower edge of the extension pipe body 33 extends into the diameter expanding section 311 to form the extension rib 34.

In an alternative embodiment, it is also possible to insert the main tube 32 into the outer tube 33 and extend the main tube 32 downward to form the extending rib 34. It should be noted that, when the drainage tube 31 is integrally disposed on the outlet tube 3, the main tube is equivalent to the portion of the outlet tube 3 located on the upper side of the drainage tube 31, and at this time, the main tube can still extend downward at the end thereof to form the extending rib.

The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the system embodiment, since it is substantially similar to the method embodiment, the description is simple, and for the relevant points, reference may be made to the partial description of the method embodiment.

The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
