[0088] like Figure 1 As shown, pipe joints in related art generally adopt a cylindrical structure. This shape is prone to rotation and slipping when assembled into equipment. Furthermore, the pipe connection direction of the pipe joint is difficult to fix due to the need to clamp the pipe, which can easily cause the pipe joint to move back and forth, resulting in an unstable fixation. Alternatively, the fixed connection direction makes it difficult to install or remove the pipe, causing inconvenience to the user. The fixing structure 20 of some pipe joints takes up additional space within the equipment, making the structure less compact. In view of this, the present invention is proposed.

[0089] The following combination Figures 2 to 12 , describing the embodiments of the present utility model.

Since the extension plane of the fixing structure 20 is parallel to the axis of the connector body 10, or the axis is located in the extension plane, the fixing structure 20 will not occupy additional space in the vertical direction after installation, and the spatial layout is more compact, which is also conducive to the miniaturization design of the equipment.

[0094] In some embodiments, as Figure 2 As shown, the fixing structure 20 includes:

[0095] Fixed body 21;

[0096] The positioning structure is provided on the fixing body 21 and is suitable for limiting the fixing structure 20 to the preset position.

[0098] Specifically, the positioning structure includes:

[0099] The edge 22 is protruding and arranged at the edge of the fixed body 21 to form a barrier.

[0100] A raised edge 22 is provided at the edge of the fixed body 21 , which, when combined with the structure at a preset position, can limit the horizontal movement of the fixed structure 20 , thereby facilitating positioning and installation.

[0105] The fixed body 21 is formed by radial extension of the connector body 10. Preferably, the two fixed ears are symmetrically arranged on the outer peripheral side of the connector body 10, and the extension planes of the two fixed ears coincide with each other. It should be noted that the surrounding edge 22 is also symmetrically arranged with the fixed body 21 as the symmetry plane. With such an arrangement, there is no need to judge the upper and lower positions of the connector assembly during installation. Figure 2 The state shown can be installed normally even after being turned upside down, thereby improving installation efficiency.

[0106] In some embodiments, as Figure 3 As shown, the joint assembly further includes a pressing assembly provided at the water inlet end 11 of the joint body 10, and the pressing assembly includes:

[0109] When in use, first insert the first clamping member 31 from the water inlet end 11 of the connector body 10, and engage the first clamping portion 311 with the second clamping portion, then put the second clamping member 32 on the pipeline to be connected and put it into the cylindrical cavity of the first clamping member 31 to engage with it, thereby completing the detachable press-fit between the pipeline to be connected and the water inlet end 11 of the connector body 10.

[0110] In some embodiments, the first clamping member 31 includes:

The oblique arrangement forms barbs that can reliably engage with the slots 13 in the connector body. The plurality of teeth are arranged at intervals to provide a certain buffer deformation space, which can also save material and reduce weight.

[0113] The inner wall of the sleeve of the first clamping member 31 forms an oblique groove that gradually expands from the inside to the outside, which is convenient for cooperation with the second clamping member 32, and is limited by the oblique groove structure to prevent the second clamping member 32 from escaping from the first clamping member 31; the first clamping part 311 of the first clamping member 31 is clamped with the second clamping part of the connector body 10 to form a connection between the clamping assembly and the connector body 10, which has a simple structure and is easy to assemble.

[0115] collar 321;

[0116] The elastic claw 322 is provided at one end of the collar 321 and extends along the axial direction of the collar 321 , and is suitable for clamping the pipeline to be connected and tightly fitting with the wall of the chute.

[0117] The elastic deformation of the elastic claws 322 facilitates the insertion of the pipeline to be connected into the fastening space formed between the elastic claws 322 , forming a clamp around the pipeline to be connected for effective positioning.

[0120] It should be noted that the connector assembly can be connected to the silicone hose with the water inlet nozzle 50. Moreover, after the compression assembly 30 is set, the water adding structure does not need to be provided with the water inlet nozzle 50, and the connector assembly can be directly connected to the pipe of the water purifier, which broadens the scope of application.

[0121] According to an embodiment of the present invention, on the other hand, Figure 11 As shown, a water adding structure is also provided, comprising:

[0122] Water supply pipe 90;

[0123] Water supply pipe 80;

[0124] The water supply pipe 90 and the water filling pipe 80 as the pipeline to be connected are connected through the joint assembly.

Since the joint assembly includes a fixed structure 20, it is convenient to fix the joint assembly, prevent the joint assembly from shifting and rotating, greatly improve the assembly reliability, and improve the reliability of the water supply structure. Moreover, the relative position of the fixed structure 20 and the joint body 10, that is, the extension plane of the fixed structure 20 is parallel to the axis of the joint body 10, or the axis is located in the extension plane, so that the extension surface of the fixed structure 20 does not intersect with the axis of the joint body 10, so that even after the fixed structure 20 is set, the volume of the joint assembly does not increase significantly, especially does not take up additional space in the vertical direction, saves space, and does not need to increase the height of the legs.

[0129] The base 100 is provided with a mounting post 70 to form the preset position;

[0130] The joint assembly or water supply structure, the fixing structure 20 and the mounting column 70 are limitedly matched.

[0131] The base 100 is provided with a mounting column 70 to facilitate cooperation with the fixing structure 20 to form a positioning for the fixing structure 20 and the joint body 10.

[0134] In some embodiments, the electrical appliance is an electric kettle.

[0135] The water supply structure of the electric kettle is provided with a joint assembly or water supply structure of the present invention. The joint assembly is fixed by a fixing structure 20 to prevent displacement and rotation of the joint assembly, greatly improving the assembly security and the reliability of the water supply structure. Moreover, the relative position of the fixing structure 20 and the joint body 10, that is, the extension plane of the fixing structure 20 is parallel to the axis of the joint body 10, or the axis is located within the extension plane, ensures that the extension surface of the fixing structure 20 does not intersect with the axis of the joint body 10. Therefore, even after the fixing structure 20 is provided, the volume of the joint assembly does not increase significantly, especially in the vertical direction. It does not occupy additional space, thus saving space. The height of the electric kettle base 100 does not need to be increased, and the structure is compact and reasonable.

[0136] The connector body 10 of the connector assembly is equipped with two fixing ears. The edges of the fixing ears are provided with a surrounding edge 22 for positioning with the mounting posts 70 (screw posts) on the base 100. The fixing ears are provided with mounting holes 211 (screw holes 71).

The water inlet end 11 of the connector body 10 is equipped with a compression structure 30 consisting of a first clamping member 31 and a second clamping member 32, as well as a sealing ring 40. The sealing ring 40 is placed in the connector body 10. The teeth on the first clamping member 31 engage with corresponding slots 13 within the connector body 10. The elastic claws 322 of the second clamping member 32 engage with corresponding beveled grooves on the inner ring of the first clamping member 31. The buckle 3221 within the second clamping member 32 is used to secure the connector to the water inlet nozzle 50.

[0139] Two fixing ears are provided on the fixing joint, and the pipe joint is fixed to the base 100 by screwing, making the fixing joint easy to assemble. The surrounding edge 22 on the fixing ear is adapted to the size of the screw column. When the fixing structure 20 is installed on the screw column, the surrounding edge 22 directly defines the position of the mounting hole 211, so that the mounting hole 211 corresponds to the position of the threaded hole 71 on the screw column. When installing the screw, there is no need to re-position the hole, which improves installation convenience.
