For example, it can be a fixed connection, a detachable connection, or an integrated connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0026] Throughout this specification, reference to terms such as "one embodiment," "specific embodiment," "illustrative," "implementation," "example," or "some embodiments" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. Throughout this specification, the illustrative use of these terms does not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0027] Figures 1 to 5 This is a schematic diagram of an embodiment of a liquid heater, comprising a glass body 1, an upper water pipe 2 disposed on the outside of the glass body 1, the upper water pipe 2 extending vertically, the lower end of the upper water pipe 2 communicating with the interior of the glass body 1, the upper end of the upper water pipe 2 communicating with a water outlet, and an annular fixing groove 3 formed on the outer surface of the glass body 1. The liquid heater also includes a panel assembly surrounding a mounting ring 401 fixed to the fixing groove 3; the liquid heater also includes an anti-siphon box 7, the lower end of the anti-siphon box 7 being connected to the upper water pipe 2 and the upper end communicating with the interior of the glass body 1. The anti-siphon box passes through the mounting ring and communicates with the glass body. The panel assembly covers the anti-siphon box and is mounted on the mounting ring. Preferably, the panel assembly covers a portion of the sidewall of the glass body, which is intended for viewing.

[0028] In the liquid heater of the present invention, by connecting the anti-siphon box 7 to the outlet pipe 6, when drainage stops and the water outlet is lower than the liquid level in the glass kettle body 1, the anti-siphon box 7 can be connected to the atmosphere to prevent siphoning from occurring in the outlet pipe 6; when the water supply pipe 2 is draining, the anti-siphon box 7 can drain the gas in the discharged water, making the water flow more stable. Moreover, the upper end of the anti-siphon box 7 directly extends into the glass kettle body 1 through the mounting hole 5, and can directly discharge the gas into the glass kettle body 1, making it safe and convenient to use. By arranging the anti-siphon box 7 at the mounting ring, the mounting ring specifically strengthens the output end of the anti-siphon box 7. The mounting hole is arranged in the fixing groove and cooperates with the mounting ring to weaken the visual difference of the hole in the glass kettle body at this location, making it less conspicuous and improving the aesthetics.

[0029] In the technical solution of the present application, a glass kettle body 1 is used, and a fixing groove 3 is provided in the glass kettle body 1. Therefore, a mounting ring 401 can be fixed in the fixing groove 3 to achieve the connection and fixation between the panel assembly and the glass kettle body 1. The connection and fixation of the glass kettle body 1 can be achieved through the panel assembly, which facilitates the installation of structural components such as handles on the panel assembly. At the same time, the anti-siphon box 7 is fixedly installed on the panel assembly, which can effectively install and fix the anti-siphon box 7, and at the same time, the upper end of the water supply pipe 2 can be fixedly connected, thereby achieving the fixation of the entire water system to the side of the glass kettle body 1. Compared with the method of fixing the anti-siphon box 7 separately to the kettle body or fixing it to the mouth of the kettle body, the structure of the present invention is relatively simple.

[0030] More specifically, the mounting ring is provided with an opening 11, the anti-siphon box is provided at the opening, and the anti-siphon box connects the portions of the mounting ring on both sides of the opening. In this manner, the anti-siphon box directly serves as a connector to connect the mounting ring, resulting in a simple structure.

[0031] In a preferred embodiment, Figure 1 and Figure 4 As shown, more specifically, the mounting ring 401 is provided with an opening 11, and the panel assembly further includes a mounting bracket 402 and an outer cover plate 22 located outside the mounting bracket. The mounting bracket 402 connects the portions of the mounting ring 401 on both sides of the opening 11, and the anti-siphon box 7 is fixed to the mounting bracket 402. By providing the opening 11 in the mounting ring 401, the mounting ring 401 can be conveniently placed in the fixing groove 3. By fixing the portions of the mounting ring 401 on both sides of the opening 11 by the mounting bracket 402, the mounting ring 401 can be fixed to the glass pot body 1. At the same time, by fixing the anti-siphon box 7 to the mounting bracket 402, the mounting bracket 402 can be used for multiple purposes and can conveniently fix the anti-siphon box 7.

[0032] In a preferred embodiment, Figure 1 、 Figure 2 As shown, a further optimization of the present invention is that the liquid heater further includes fasteners that secure the anti-siphon box 7 to the mounting bracket 402 and connect the portions of the mounting ring 401 on both sides of the opening 11. This allows the fasteners to simultaneously secure the anti-siphon box 7 and the mounting ring 401, simplifying the installation structure and process. Specifically, the fasteners may be threaded fasteners.

[0033] exist Figure 1 In the illustrated embodiment, more specifically, as shown in the figure, the anti-siphon box 7 has two ear plates 16 , and the fasteners include bolts, which pass through the ear plates 16 and the mounting bracket 402 and are then fixed to the mounting ring 401 .

[0034] exist Figure 1 In the illustrated embodiment, more specifically, the panel assembly forms a connecting post with a threaded hole, and the anti-siphon box 7 is provided with an ear plate 16, through which screws are passed and fixed to the connecting post.

[0035] The structure of fasteners fixing the anti-siphon box 7 and the mounting ring 401 at the same time is not limited to Figure 1 In an alternative embodiment, other arrangements may be used, such as threaded posts provided on both sides of the opening 11 of the mounting ring 401, which pass through the mounting bracket 402. The fasteners may be nuts that are screwed onto the threaded posts. Alternatively, the threaded posts may be heat-seal posts that pass through the mounting bracket 402 and the anti-siphon box 7 and are then heat-sealably connected to the anti-siphon box 7.

[0036] The method for fixing the anti-siphon box 7 to the mounting bracket 402 is not limited to Figure 1 In an alternative embodiment, as shown in Figure 4 As shown, the anti-siphon box 7 can also be fixed separately on the mounting bracket 402. The fixing method is not limited to the screw fixing method, and methods such as bonding and welding can also be used.

[0037] A further optimization of the present invention is that one of the panel assembly and the anti-siphon box 7 is provided with a positioning pile 17, and the other is provided with a positioning hole, and the positioning pile 17 is inserted into the positioning hole. Figure 1 and Figure 2 As shown, through such a setting, the position of the anti-siphon box 7 in the panel assembly can be quickly determined during assembly, and the anti-siphon box 7 can also be initially fixed, which can facilitate installation. In the illustrated embodiment, the panel assembly is provided with two positioning stakes 17, and the anti-siphon box 7 is provided with matching positioning holes. However, due to the viewing angle, the positioning holes on the anti-siphon box 7 are not drawn, which does not affect the understanding of those skilled in the art of the setting method of providing positioning holes for the positioning stakes to be inserted in the anti-siphon box. In an alternative embodiment, positioning holes can also be provided in the panel assembly, and positioning stakes 17 can be provided in the anti-siphon box 7.

[0038] A further optimization of the present invention is that the bottom wall of the fixing groove 3 is provided with a mounting hole 5, through which the anti-siphon box 7 passes and communicates with the interior of the glass kettle body 1. By providing the mounting hole 5, the upper end of the anti-siphon box 7 can be directly extended into the glass kettle body 1. Compared with the prior art method in which the anti-siphon box 7 passes over the mouth of the glass kettle body 1, there is no need to provide a fixing structure for the anti-siphon box 7 at the mouth of the glass kettle body 1, which simplifies the structure of the glass kettle body 1 at the mouth of the kettle, making it easier for the glass kettle body 1 to be fastened to the matching kettle lid at the mouth of the kettle.

[0039] like Figure 1 and Figure 4 As shown, the anti-siphon box 7 is fixed at the end of the mounting hole 5 to form a limiting rib 8, and the limiting rib 8 abuts against the inner surface of the glass pot body for limitation. A limiting groove 9 is also provided on the anti-siphon box 7, and the part of the glass pot body 1 at the edge of the mounting hole 5 is clamped in the limiting groove 9, which can fix the end of the anti-siphon box 7 to the mounting hole 5.

[0040] Regarding the setting of the communication between the anti-siphon box 7 and the glass body 1, in a preferred embodiment, more specifically, the anti-siphon box 7 includes an upper connecting portion 14 and a hollow silicone plug 15, and the silicone plug 15 passes through the mounting hole 5 from the inner side of the glass body 1 and is connected to the upper connecting portion 14. Figure 1 As shown, the upper connecting portion 14 is provided with a protrusion, and the upper connecting portion 14 is hollow and communicates with the upper water pipe 2. The silicone plug 15 passes from the inside of the glass kettle body 1 to the outside and is then interference-fitted onto the upper connecting portion 14, thereby facilitating assembly and fixing of the silicone plug 15. In an alternative embodiment, the silicone plug 15 can also be processed to be inserted into the upper connecting portion 14 through interference fit.

[0041] The way in which the anti-siphon box 7 passes through the mounting hole 5 is not limited to Figure 1 In an alternative embodiment, it can also be as shown in Figure 4 As shown, the anti-siphon box 7 is integrally formed with a plug that is inserted into the mounting hole 5 .

[0042] The structure of fixing the anti-siphon box 7 to the panel assembly is not limited to Figure 1 The structural form of the embodiment shown in FIG, in an alternative embodiment, can also be as Figure 4 、 Figure 5 As shown, the anti-siphon box 7 is provided with a water outlet pipe body 601 connected to the water outlet pipe 6 of the upper water pipe 2, and the lower end of the anti-siphon box 7 is provided with a connector 602 sleeved on the upper end of the water outlet pipe 6; the water outlet pipe 6 is separately fixed on the mounting bracket 402. Figure 4 In the embodiment shown, the water outlet pipe is provided with an ear plate, the mounting bracket is provided with a connecting column with a threaded hole, and the water outlet pipe 6 is fixed to the connecting column of the mounting bracket 402 by screws.

[0043] exist Figure 1 In the embodiment shown, with respect to the structure of the anti-siphon box 7, to be more specific, the anti-siphon box 7 has a water guide cavity 12 connected to the upper end of the water supply pipe 2, and a siphon cavity 13 connected to the water guide cavity 12. The water outlet is provided at one end of the water guide cavity 12 away from the water supply pipe 2. The siphon cavity 13 extends upward from the water guide cavity 12 and is connected to the glass pot body 1. The portion of the anti-siphon box 7 extending upward from the siphon cavity 13 is laterally divided into a first siphon portion 701 and a second siphon portion 702, and the first siphon portion 701 and the second siphon portion 702 are split structures.

[0044] like Figure 1 and Figure 2 、 Figure 3 As shown, by configuring the anti-siphon box 7 to have a water guide cavity 12 and a siphon cavity 13, the anti-siphon box 7 can simultaneously drain water and guide air. Furthermore, by dividing the anti-siphon box 7 into a first siphon portion 701 and a second siphon portion 702 at the siphon cavity 13, the internal cavity structure of the anti-siphon box 7 can be easily processed, and the fixing structure of the anti-siphon box 7 to the panel assembly can also be easily processed.

[0045] Regarding the connection mode of the first siphon part 701 and the second siphon part 702, Figure 1 In the embodiment shown, more specifically, one of the first siphon part 701 and the second siphon part 702 has a slot 18, and the other has a rib 19, the rib 19 is inserted into the slot 18, and the rib 19 is welded to the slot 18. Figure 3 As shown, the first siphon part 701 is provided with an annular dowel 19, and the second siphon part 702 is provided with a slot 18. After the dowel 19 is inserted into the slot 18, it is fixed by ultrasonic welding, so that the first siphon part 701 and the second siphon part 702 can be stably connected and not prone to water leakage. In an alternative embodiment, the first siphon part 701 and the second siphon part 702 can also be fixed in other ways. For example, the first siphon part 701 and the second siphon part 702 can be fixed by bonding or screw connection. In addition, in the embodiment drawings, the first siphon part 701 and the second siphon part 702 are in the form of left and right parts. Those skilled in the art can also imagine that the first siphon part 701 and the second siphon part 702 are in the form of upper and lower parts.

[0046] exist Figure 1 In the embodiment shown, more specifically, the second siphon part 702 is formed with a drainage head 21, and the drainage head 21 is provided with the water outlet, and the first siphon part 701 is provided with a water inlet head 20, and the water inlet head 20 is vertically plugged and connected to the upper water pipe 2. As shown in the figure, when the anti-siphon box 7 is processed separately, the water outlet and the water inlet head 20 can be processed separately, and the connection structure of the anti-siphon box 7 can be easily processed. In the embodiment shown in the figure, the water inlet head 20 is inserted into the upper water pipe 2 with an interference fit. Figure 2 As shown, the drainage head 21 can also be plugged into and connected to the water outlet head 10, and the water outlet head 10 directly drains water outward.

[0047] It should be noted that, in the illustrated embodiment, the bottom of the upper water pipe is connected to the water pump at the bottom of the inner tank. This part of the structure can adopt the structure of the existing electric kettle. In the figure, the connection structure at the bottom of the upper water pipe is not shown, which does not affect the implementation of the technical solution of the present invention.

[0048] Anything not described in the present invention can be achieved by adopting or drawing on existing technologies.

[0049] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention.
