Description

Technical Field

[0001] The utility model relates to the technical field of electric couplers, in particular to a novel coupler structure and an electric water bottle having the same. Background Art

[0002] This section only provides background information related to the present application to help those skilled in the art understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] At present, the electric coupler has been widely used in electric water bottles, which includes an upper coupler and a lower coupler, and a plurality of ring-shaped metal electrodes are evenly arranged on the upper coupler and the lower coupler. The upper coupler is inserted into the lower coupler and the corresponding metal electrodes are in contact to form electrical connection. The electric coupler can not only meet the separation of the upper and lower couplers to separate the kettle body and the fuselage, but also meet the requirement that the bottom of the kettle body can be inserted from any direction and adapted to the fuselage, which is very convenient to use.

[0004] As people's living standards continue to improve, consumers have put forward higher requirements for electric water bottles, and people hope to be able to automatically control the water output of electric water bottles. To this end, some merchants set an upper water inlet pipe in the central opening of the upper coupler, set an upper valve core connected to the spring in the upper water inlet pipe, set a lower water inlet pipe in the central opening of the lower coupler, and set a lower valve core connected to the spring in the lower water inlet pipe. Therefore, when the upper and lower couplers are coupled and connected, the upper valve core and the lower valve core are mutually pressed to connect the upper water inlet channel with the lower water inlet channel, so that water can be discharged; when the upper and lower couplers are separated, the upper valve core and the lower valve core are moved by the spring reset to seal the upper water inlet channel and the lower water inlet channel respectively.

[0005] However, the above-mentioned setting method has the following problems: first, since it is necessary to respectively set the valve core assembly in the upper water inlet pipe and the lower water inlet pipe, the structure is complicated, the number of parts is large, and the assembly is difficult; second, since there is a water connection between the upper coupler and the lower coupler, if the seal is not tight, it will cause water leakage, which is not only easy to breed bacteria and produce odor, but also easy to burn the coupler; finally, when the upper and lower couplers are separated, there is residual water in the upper water inlet pipe of the upper coupler and the lower water inlet pipe of the lower coupler. This section of residual water is prone to secondary pollution. When the upper and lower couplers are re-coupled and connected, the residual water will be pumped out and drunk by the user, thereby causing adverse effects on the user's body. Utility Model Content

[0006] In order to overcome the defects of the above-mentioned prior art, the utility model provides a new coupler structure. By adopting a split water pump, when the upper coupler is coupled with the lower coupler, it can simultaneously meet the electrical connection and realize the water pumping function; when the upper coupler is separated from the lower coupler, since there is no water connection between the upper coupler and the lower coupler, there will be no leakage, water seepage and the like, thereby ensuring complete isolation of water and electricity, making it safer and more hygienic to use.

Therefore, when the driving motor 22 is started, the impeller 13 can be driven to rotate to realize the pumping function.

[0045] The coupler structure of the utility model adopts a split water pump, and sets the driving component with a driving motor 22 in the water pump on the lower coupler 2, and sets the driven component with an impeller 13 and a water inlet housing 12 on the upper coupler 1. In this way, when the upper coupler 1 is coupled with the lower coupler 2, the electrical connection and the water pumping function of the water pump can be achieved at the same time; when the upper coupler 1 is separated from the lower coupler 2, since there is no water connection between the upper coupler 1 and the lower coupler 2, there will be no leakage, water seepage and the like, thereby ensuring that water and electricity are completely isolated, and the use is safer and more hygienic.

In addition, the driven component also includes a ring-shaped sealing ring 17, which is arranged at the connection between the water inlet bracket 121 and the bottom plate 122 to achieve waterproof sealing.

[0054] Of course, in other embodiments, the water inlet bracket 121 and the bottom plate 122 may also be sealed by ultrasonic welding, which is not limited here.

[0055] Furthermore, the impeller 13 includes an impeller body 131 and an impeller internal component 132 disposed on the impeller body 131, wherein the impeller internal component 132 is fixedly sleeved on the top of the first shaft body 14, and the bottom of the first shaft body 14 is rotatably disposed on the bottom plate 122.
