[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0033] The utility model aims to provide a double-channel water-passing coupler, which can ensure the synchronization of the water level in a water level gauge and the water level in a kettle.

[0034] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0035] See also Figures 1 to 7 The present embodiment provides a dual-channel water-through coupler, including a coupler female 200 installed at the bottom of the kettle 100, a coupler male 300 used to cooperate with the coupler female 200, and also includes: a dual-channel water-through pipe 400 arranged in the middle mounting hole of the coupler male 300, the dual-channel water-through pipe 400 includes a main water-through pipe 410 and a connecting pipe 420 arranged inside the main water-through pipe 410, the connecting pipe 420 is used to connect the kettle 100 and the water level gauge 600, the top of the connecting pipe 420 is higher than the main water-through pipe 410, and a water-through hole 421 is provided on the top and / or side wall of the connecting pipe 420 near one end of the coupler female 200.

[0036] Specifically, Figure 1As shown, the coupler female 200 is installed at the bottom of the kettle 100, and a channel for water supply is provided in the middle of the coupler female 200, and a steel ball is provided in the channel. A through-type mounting hole is provided in the middle of the coupler male 300, and a double-channel water pipe 400 is provided in the mounting hole; the coupler male 300 is used to cooperate with the coupler female 200, and when the coupler female 200 and the coupler male 300 are fully matched, the double-channel water pipe 400 is just connected to the middle channel of the coupler female 200. In this way, when the coupler male 300 and the coupler female 200 are moved up and down, the double-channel water pipe 400 is connected to the middle channel of the coupler female 200. When plugged in, the double-channel water pipe 400 will extend into the through hole in the middle of the coupler mother 200 and lift up the steel ball inside it, so that the double-channel water pipe 400 in the coupler male 300 can be connected with the interior of the kettle 100 through the coupler mother 200, so that water can be stored in the kettle 100 or water can be taken out from the kettle 100. When the coupler mother 200 is separated from the coupler male 300, the steel ball will fall under the action of gravity and just block the channel connecting to the interior of the kettle 100, thereby preventing water in the kettle 100 from leaking.

[0037] Further, such as Figure 2 and Figure 4 As shown, in order to enable the water level in the kettle 100 to maintain smooth communication with the water level gauge 600 connected to the outside, that is, to achieve the effect that after the liquid level in the kettle 100 changes, the water level gauge 600 connected thereto can also quickly synchronize the liquid level under the action of the communicating vessel, the dual-channel water pipe 400 in the middle of the coupler male 300 includes a main water channel and a connecting pipe 420 arranged inside it, wherein the main water pipe 410 is used to communicate with the inside of the kettle 100, to transport water to the inside or to take water out, and the connecting pipe 420 has a diameter slightly smaller than the main water pipe 410, and is used to communicate with the external water level gauge 600. In this way, the communicating vessel principle can be used to achieve rapid synchronization between the liquid level in the kettle 100 and the liquid level of the water level gauge 600, thereby improving the accuracy of water level detection. Figure 7 As shown; in addition, in order to prevent the steel ball in the coupler mother 200 from falling when the coupler mother 200 is matched with the coupler male 300, and blocking the top outlet of the dual-channel water pipe 400 and making the dual-channel water pipe 400 ineffective, the top of the connecting pipe 420 is set slightly higher than the main water pipe 410 in the embodiment of the present application; in addition, the top of the connecting pipe 420 or the side arm of the connecting pipe 420 can be provided with a water hole 421 according to actual conditions, or the top and side wall of the connecting pipe 420 are provided with a water hole 421, as shown in the figure; Figure 6 As shown, in this way, the steel balls are set up through the connecting pipe 420, so that the main water pipe 410 can supply water normally, and the connecting pipe 420 is connected to the inside of the kettle 100 and the water level gauge 600 through the water hole 421, thereby ignoring the obstruction of the water flow caused by the steel balls in the coupler mother 200.

[0038] Specifically, the female coupler 200 installed at the bottom of the kettle 100 can cooperate with the male coupler 300 to realize water delivery into the kettle 100 or water delivery from the inside of the kettle 100 to the outside, wherein the middle of the male coupler 300 is penetrated with a mounting hole, and a double-channel water pipe 400 is arranged in the mounting hole. The double-channel water pipe 400 includes an external main water pipe 410 and a connecting pipe 420 installed inside the main water pipe 410. The main water pipe 410 is used to deliver water into the kettle 100 or to take water out of the kettle 100, while the connecting pipe 420 only connects the water level gauge 600 inside the kettle 100 with the outside, and the two are connected by According to the principle of connecting pipes, the liquid level in the water level gauge 600 can be kept consistent with the liquid level in the kettle 100; it should be noted that when the coupler female 200 and the coupler male 300 are in cooperation, a steel ball is provided in the channel in the middle of the coupler female 200 for water supply, and in order to prevent the steel ball from falling and blocking the top of the dual-channel water pipe 400, the top of the connecting pipe 420 is higher than the main water pipe 410 for supporting the steel ball, and an additional water hole 421 is provided on the side wall of the connecting pipe 420, so that the steel ball in the coupler female 200 will not affect the functioning of the main water pipe 410 and the connecting pipe 420.

[0039] Preferably, the diameter of the connecting pipe 420 is smaller than the diameter of the main water pipe 410 , and the outer wall of the connecting pipe 420 is tangent to the inner wall of the main water pipe 410 .

[0040] It can be understood that the communication pipe 420 only needs to connect the inside of the kettle 100 and the water level gauge 600. Therefore, the communication pipe 420 is arranged inside the main water pipe 410, that is, the diameter of the communication pipe 420 is smaller than the diameter of the main water pipe 410, and in this embodiment, the communication pipe 420 is arranged tangent to the main water pipe 410. Figure 4 and Figure 5 Such arrangement is to facilitate the fixing of the connecting pipe 420 in the main water pipe 410, and the connecting pipe 420 can be fixed by a simple structure to avoid the connecting pipe 420 from changing its position at will during use.

[0041] Preferably, a fixing member 430 is provided on the outer circumference of the dual-channel water pipe 400 , and the fixing member 430 cooperates with a groove in the middle mounting hole of the coupler male 300 to limit the axial movement of the dual-channel water pipe 400 .

[0042] Specifically, Figures 2 to 4As shown, on the outer periphery of the dual-channel water pipe 400, a plurality of sets of fixing parts 430 are arranged. The fixing parts 430 are radial protrusions along the dual-channel water pipe 400. When the dual-channel water pipe 400 is installed inside the mounting hole in the middle of the coupler male 300, in order to prevent its axial movement, the inner wall of the mounting hole is provided with corresponding grooves. Each groove can match with the fixing parts 430 when the dual-channel water pipe 400 is installed in place, thereby making the dual-channel water pipe 400 firmly installed inside the coupler male 300.

[0043] Of course, the shape and quantity of the fixing member 430 can be adjusted according to actual conditions, and are not specifically limited herein.

[0044] Preferably, a limiting member 440 is provided on the outer circumference of the dual-channel water pipe 400 along the length extension direction thereof, and the limiting member 440 is used to prevent the dual-channel water pipe 400 from rotating in the middle of the coupler male 300 .

[0045] Further, such as Figure 2 and Figure 3 As shown, in this embodiment, a limit member 440 with extended axial extension is also provided on the outer circumference of the dual-channel water pipe 400, and a corresponding limit groove is also provided in the mounting hole in the middle of the coupler male 300. This arrangement can effectively prevent the dual-channel water pipe 400 from rotating inside the coupler male 300.

[0046] Preferably, a pipe joint 500 is also included, which is arranged at the bottom of the dual-channel water pipe 400. The pipe joint 500 is an L-shaped structure as a whole. The pipe joint 500 is sleeved on the outer periphery of the dual-channel water pipe 400, and its horizontal bend portion is connected to the main water pipe 410.

[0047] It can be understood that in order to facilitate the connection of the dual-channel water pipe 400 to the water inlet and outlet pipes and the pipe connecting the water level gauge 600, a pipe joint 500 is provided at its lower end. The pipe joint 500 is an L-shaped structure as a whole, and is sleeved on the outer periphery of the dual-channel water pipe 400, but its horizontal bending portion is connected to the main water pipe 410, and the connecting pipe 420 directly extends out of the pipe joint 500. This arrangement can quickly and conveniently connect the dual-channel water pipe 400, and avoid the connection pipes being located in the same position, resulting in crowded pipe installation.

[0048] Preferably, the pipe joint 500 is elastic and is made of gas-phase silica gel.

[0049] Furthermore, in order to facilitate the connection of pipes and prevent them from scratching the dual-channel water pipe 400, the pipe joint 500 is preferably made of gas-phase silica gel. The pipe joint 500 made of such material has better sealing when connected to other water pipes.

[0050] Preferably, the material of the dual-channel water pipe 400 is polypropylene.

[0051] In this embodiment, the dual-channel water pipe 400 is preferably made of polypropylene, which has good and stable chemical properties, is economical, and is convenient for the production and manufacturing of the dual-channel water pipe 400.

[0052] Preferably, the dual-channel water pipe 400 is integrally formed by injection molding.

[0053] In this embodiment, for the overall strength of the dual-channel water pipe 400 and to facilitate its production, the dual-channel water pipe 400 can be integrally formed by injection molding using an injection molding machine, which greatly improves its production efficiency.

[0054] Preferably, the cross-sectional area of ​​the main water pipe 410 in the dual-channel water pipe 400 is greater than 4.5 mm 2 .

[0055] Specifically, the cross-sectional area of ​​the main water pipe 410 is greater than 4.5 mm 2 This can ensure that the water supply can flow smoothly through it, and the connecting pipe 420 can be adjusted according to actual conditions, which is not specifically limited in this article.

[0056] Preferably, the cross-sectional area of ​​the water hole 421 is greater than 1.5 mm 2 .

[0057] In addition, in this embodiment, the water hole 421 is preferably a circular through hole with a cross-sectional area greater than 1.5 mm. 2 The communicating pipe 420 can achieve the best communicating effect.

[0058] The utility model also provides a water purifier, including the dual-channel water coupler described above; other parts of the water purifier can refer to the prior art and will not be elaborated in this article.

[0059] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0060] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
