The first limiting part 112 is arranged on the inner side wall of the water outlet hole 111, the second limiting part 210 is arranged on the outer side wall of the metal water outlet nozzle 20, the first limiting part 112 is used for limiting the second limiting part 210 to move towards the outlet direction of the water outlet hole 111, and further limiting the metal water outlet nozzle 20 to move towards the outlet direction of the water outlet hole 111, so that the probability that the metal water outlet nozzle 20 loosens or even breaks away from the water outlet hole 111 can be reduced, and the installation stability of the metal water outlet nozzle 20 is improved.

With respect to the specific structures of the first limiting portion 112 and the second limiting portion 210, further, in some embodiments, as shown in fig. 2, the first limiting portion 112 is a first protruding portion, and the second limiting portion 210 is a second protruding portion, where in the case that the metal nozzle 20 is inserted into the water outlet 111, the second protruding portion is located on a side of the first protruding portion facing the inlet of the water outlet 111.

In these embodiments, two protruding portions are used for limiting, specifically, in the process of inserting the metal water outlet nozzle 20, the second protruding portion can be pushed to pass over the first protruding portion, and then the second protruding portion is limited to move towards the outlet direction of the water outlet hole 111 by the first protruding portion, so that the structure is simple, and the processing and the assembly are convenient. Moreover, it is advantageous that the inner diameter of the portion of the water outlet hole 111 surrounding the metal water outlet nozzle 20 is substantially unchanged (irrespective of the first protrusion), and the outer diameter of the metal water outlet nozzle 20 is substantially unchanged (irrespective of the second protrusion), facilitating the processing of the water outlet hole 111 and the metal water outlet nozzle 20.

As an example, one of the first protrusion and the second protrusion is an annular limit rib, and the other is a plurality of sub-protrusions circumferentially spaced apart.

The annular limiting ribs and the plurality of sub-protruding parts which are distributed at intervals are mutually limited to prevent the metal water outlet nozzle 20 from separating from the water outlet hole 111, on one hand, because the limiting ribs are annular, even if the metal water outlet nozzle 20 rotates and deviates by a certain angle in the process of being inserted into the water outlet hole 111, the plurality of sub-protruding parts can also correspond to the annular limiting ribs to be in limiting fit, so that the situation of limiting failure caused by dislocation can not occur; on the other hand, because the plurality of sub-protruding portions are distributed at intervals, compared with the first protruding portion and the second protruding portion which are annular limiting ribs, the metal water outlet nozzle 20 is conveniently and smoothly inserted into the water outlet hole 111 to be inserted in place, and clamping stagnation is not easy to occur. Moreover, the annular limiting ribs are adopted for limiting, and the assembly gap between the metal water outlet nozzle 20 and the water outlet hole 111 can be shielded, so that a large amount of liquid is prevented from flowing out through the gap between the metal water outlet nozzle 20 and the water outlet hole 111.

Specifically, as shown in fig. 3, 5 and 6, an annular limit rib may be disposed on an inner sidewall of the water outlet 111, where the default annular limit rib is distributed along a circumferential direction of the water outlet 111, and a plurality of sub-protrusions circumferentially spaced apart are disposed on an outer sidewall of the metal water outlet 20, where the default plurality of sub-protrusions are distributed along the circumferential direction of the metal water outlet 20. The metal water outlet nozzle 20 is convenient to process, in the process of inserting the metal water outlet nozzle 20 into the water outlet hole 111, the plurality of sub-protruding parts are conveniently extruded to pass through the annular limiting ribs, so that the annular limiting ribs limit the plurality of sub-protruding parts to move towards the outlet direction of the water outlet hole 111, and the metal water outlet nozzle 20 is convenient to install and firm to install.

A plurality of sub-protruding parts distributed in the circumferential direction can be further arranged on the inner side wall of the water outlet 111, wherein the default sub-protruding parts are distributed along the circumferential direction of the water outlet 111, and annular limiting ribs are arranged on the outer side wall of the metal water outlet 20, and the default annular limiting ribs are distributed along the circumferential direction of the metal water outlet 20. In the process of inserting the metal water outlet nozzle 20 into the water outlet hole 111, the annular limiting ribs are convenient to extrude the plurality of sub-protruding parts to cross the plurality of sub-protruding parts, so that the plurality of sub-protruding parts limit the annular limiting ribs to move towards the outlet direction of the water outlet hole 111, and the metal water outlet nozzle 20 is convenient to install and firm to install.

The water outlet 111 has an inlet and an outlet, and when the liquid heating apparatus pours liquid, the liquid flows to the outlet through the inlet, the outlet direction of the water outlet 111 is the direction in which the outlet is located, and the inlet direction of the water outlet 111 is the direction in which the inlet is located.

Further, as shown in fig. 3 and 4, the sub-protrusions are bumps. Simple structure, convenient processing need not to exert very big power moreover and can make bump and spacing cooperation of annular spacing muscle, makes things convenient for metal water outlet nozzle 20 cartridge to put in place.

On the other hand, the limiting effect can be ensured, and the situation that the metal water outlet nozzle 20 is separated from the water outlet hole 111 due to the too small number of the sub-convex parts is avoided.

Further, the protrusion height of the sub-protrusion ranges from 0.2mm to 0.5mm. On the one hand, the sub-convex parts can have enough limiting area to be in limiting fit with the annular limiting ribs, so that the limiting effect is ensured. On the other hand, since the first limiting portion 112 and the second limiting portion 210 are both protruding structures, the gap between the outer sidewall of the metal water outlet nozzle 20 and the inner sidewall of the water outlet hole 111 refers to the protruding height of the two protruding structures, so that the protruding height of the sub-protruding portion does not exceed 0.5mm, the hole diameter of the water outlet hole 111 is not required to be too large to accommodate the sub-protruding portion, which is beneficial to making the gap between the outer sidewall of the metal water outlet nozzle 20 and the inner sidewall of the water outlet hole 111 smaller, thereby avoiding the liquid from flowing out largely through the gap.

At this time, to further facilitate the insertion of the metal water outlet 20 into the water outlet 111, the first recess may be disposed at one end of the outer sidewall of the metal water outlet 20 near the inlet of the water outlet 111, so that in the process of inserting the metal water outlet 20, the metal water outlet 20 may be first inserted into the water outlet 111 deeper until reaching the third protrusion, and then the metal water outlet 20 is pushed downward, and the third protrusion relatively moves for a short distance to be inserted into the first recess.

As an example, the first limiting portion 112 is a first concave portion. At this time, to further facilitate the insertion of the metal water outlet 20 into the water outlet 111, the first concave portion may be disposed at one end of the inner sidewall of the water outlet 111 near the outlet thereof, and then in the process of inserting the metal water outlet 20, the metal water outlet 20 may be inserted into the water outlet 111 deeper, and then the metal water outlet 20 is pushed downward, so that the third convex portion moves a shorter distance in the water outlet 111 and may be inserted into the first concave portion.
