Description

Power supply base of electric kettle

Technical Field

The utility model relates to a small-size domestic appliance field, concretely relates to power base of electric kettle.

Background

The electric kettle for heating drinks is very commonly applied in daily life, and the mode of connecting the electric kettle with a power supply mainly has two modes, one mode is to directly arrange a power wire connected with the power supply on the electric kettle, and the other mode is to place the electric kettle on a power supply base through a power supply base connecting unit. The electric kettle can be separated from the power base in the latter mode, so that when the beverage needing to be heated is poured or poured out, a power line does not need to be dragged, and the electric kettle is more convenient to use.

In consideration of storage, a power base sold in the market is often set to store a part of a power line in the power base, a storage groove is formed in the power base in a simpler mode, and the power line is manually placed into the storage groove when not used, so that the power base is very inconvenient and is not beneficial to arrangement of the power line. As an improvement, research and development personnel in the industry have designed a structure that can realize accomodating the power cord in power base with the mode of coiling through the lower cover of rotatory power base, for example the structure that chinese utility model patent CN201904521U disclosed, then the scheme of this patent need set up the combination of a plurality of lids, has increased power base's complexity.

The above description is included in the technical recognition scope of the inventors, and does not necessarily constitute the prior art.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a power base of electric kettle, a serial communication port, include: the power cord, the upper cover, the lower cover and the lower connector;

the upper cover and the lower cover are buckled and connected and can rotate relatively;

the upper cover and the lower cover are connected in a buckling manner to form an accommodating space, and the accommodating space comprises at least one annular cavity channel; the lower connector is arranged in the accommodating space, and the power line is connected with the lower connector and is wound on the annular cavity;

An annular wall part 121 is arranged in the accommodating space, the annular wall part 121 is provided with a passage opening 1211, and the fixing unit 160 is arranged at the passage opening 1211;

the accommodating space is further provided with a mounting wall portion 122 located inside the annular wall portion 121, and the lower connector 130 is fixed by the mounting wall portion 122. For example, a notch is formed in an upper mouth portion of the mounting wall portion, and a protrusion is formed in an outer wall of the mating lower connector, or alternatively, positions where the notch and the protrusion are provided are exchanged.

The fixing unit 160 is a structure that compresses a segment of the power cord 130 and restricts the movement of the segment.

As shown in the figure, the fixing unit may be, for example, a pressing plate, and the pressing plate is fixed to the lower cover or the upper cover by a bolt, and presses a certain portion of the power line, so that the certain portion and the lower connector are relatively fixed. Other structures can be selected instead of, for example, forming a clamping opening on the lower cover or the upper cover and then installing the wire pressing hoop.

As shown, an annular wall portion 121 and a mounting wall portion 122 are formed on the lower cover 122, and the upper cover 111 has an outer annular wall portion 115 covering the lower cover 120;

the lower connector 130 includes a first annular shoulder supported by the mounting wall portion 122; the inner cover 150 has a middle ring wall part covering the outer side of the ring wall part 121, the inner cover 150 has a first through hole 151 and a supporting surface 153, the lower side edge of the through hole 151 is lapped on the first ring shoulder part; the upper cover 110 has a second through hole 114, and the lower edge of the second through hole 114 is overlapped on the supporting surface 153.

In an embodiment not shown in the figures, the outer wall of the annular wall is provided with a second annular shoulder which supports the lower end of the intermediate annular wall.

The lower end of the middle ring wall part formed by the inner cover is supported by a shoulder part formed by the outer wall of the annular wall part, so that the sealing effect of the annular cavity channel is further enhanced. Alternatively, a snap-fit structure may be provided between the annular wall and the middle annular wall to secure the inner cap relative to the lower cap. The fastening structure is realized by, for example, providing a fastener on the annular wall, and correspondingly providing a fastener groove 152 on the middle annular wall; instead, the positions of the catch and the catch groove are interchangeable.

The edge of the lower cover 120 is formed with a bending part 123; the lower end opening of the outer annular wall part 115 is provided with a support structure 112 along the annular direction;

the bending portion 123 overlaps the supporting structure 112 such that the lower cover 120 can rotate relative to the upper cover 110.

The inner side of the outer annular wall 115 at the opening 111 is provided with a guide plate 113 comprising: a guide part which is annularly parallel or tangent to the upper cover 110 and is connected with the connecting part of the guide part and the inner wall of the upper cover; the connecting portion is flush with one side of the opening 111.

The power cord 140 is coiled in a single turn around the annular channel.

The lower cover 120 is formed at a bottom surface thereof with a pair of grooves 124.

In the embodiment not shown in the drawings, in addition to the foregoing many preferred manners, alternatively, both the annular wall portion and the mounting portion may be disposed inside the upper cover, and a similar technical purpose may also be achieved.

The power base of the existing product has a complex structure and poor compactness. And, the power cord is coiled by a plurality of strands, if the actions of pulling the power cord and rotating the wire spool are not coordinated, for example, the rotation is fast, the pulling is slow, the plurality of strands of power cords can be crowded together, the paying-off resistance and the pause feeling occur, and the smoothness is not enough. And the power supply at the outlet of the power supply line is bent by approaching a right angle, if the power supply is rotated fast and pulled slowly, the power supply line at the outlet is possibly bent, and the service life of the power supply line is possibly shortened.

As disclosed in the above embodiments, the solution disclosed in the embodiments of the present invention can fix the lower connector only by the cooperation of the upper cover and the lower cover, so as to simplify the structure and improve the compactness; the interval that the cooperation inner cup set up can play the effect of certain separation rivers and steam, and the lateral wall of connector is formed with annular shoulder down, and the overlap joint is in the annular wall top, in case there is the water infiltration, at first gets into the annular chamber in the outside and says, can not directly get into the position of connector under the installation, plays sealed effect when simplifying the structure. And a built-in guide structure is arranged at the opening at the outer side, so that the power cord can be conveniently matched and discharged. And there is no need to form a protruding tangential guide structure at the outside. The cooperation single circle is coiled the setting, then can be more smooth and easy when the power cord receive and releases.

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.

The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
