[0041] like Figures 1 to 4As shown, the present application provides a coupler that is safe to use, including a lower coupler 10 and a fixed bracket 11, wherein the fixed bracket 11 is provided with a accommodating cavity 12, wherein the lower coupler 10 is fixed to the upper end of the accommodating cavity 12, wherein a plurality of wiring terminals 101 of the lower coupler 10 extend into the accommodating cavity 12, and wherein the fixed bracket 11 is further provided with a first limiting portion 13 and a second limiting portion 14, wherein a strong wire 15 and a weak wire 16 connected to the wiring terminal 101 are respectively accommodated in the first limiting portion 13 and the second limiting portion 14, so that the strong wire 15 and the weak wire 16 are separately arranged.

[0042] The safe coupler of the present application can achieve separation of strong and weak electricity in the wiring harness at the lower coupler 10, reduce interference of strong electricity on weak electricity signals, make weak electricity more stable, and improve the safety performance of the product; different limiting parts are used to accommodate the strong wire 15 and the weak wire 16 respectively, and while achieving separation of strong and weak electricity, the wiring harness can be limited, making the wiring harness arrangement more orderly, preventing the disorderly arrangement of the wiring harness from affecting the electrical connection effect or causing installation interference, etc., optimizing the installation effect of the lower coupler 10 and the connection effect of the lower coupler 10 with other components; in addition, the wiring terminal 101 of the lower coupler 10 extends into the accommodating cavity 12, and the connection position between the lower coupler 10 and other components can be protected by the accommodating cavity 12, which can prevent short circuit, leakage, etc. caused by contact with water, thereby improving the safety of product use.

[0043] The coupler can be applied to a tea bar machine, which includes a machine body and a kettle, for example, a lower coupler 10 is mounted on the machine body and fixed to a fixed bracket 11, and an upper coupler is provided at the bottom of the kettle, and electrical connection can be achieved through coupling of the upper and lower couplers. Among them, the strong wire 15 connected to the lower coupler 10 includes, for example, a live wire, a neutral wire, a ground wire, etc., and the weak wire 16 is mostly connected to a detection element. By separating strong and weak electricity, it is possible to prevent the weak current signal from being charged or interfered due to leakage of strong electricity, thereby improving the safety and reliability of use.

[0044] The structures of the first limiting portion 13 and the second limiting portion 14 may be the same or different, and a plurality of the first limiting portion 13 and the second limiting portion 14 may be provided respectively, so as to achieve the limiting of multiple wire harnesses.

[0045] As a preferred embodiment of the present application, the fixed bracket 11 has a circumferential wall 111 to enclose a accommodating cavity 12 with an open bottom, and the first limiting portion 13 is a slot arranged on the circumferential wall 111, the slot extends upward from the bottom end of the circumferential wall 111 and a first opening 17 is provided at the bottom of the slot.

[0046] The use of a slot can facilitate the positioning of the wiring harness, and when the wiring harness is inserted into the slot from the first opening 17, one end of the wiring harness can enter the accommodating cavity 12 and be connected to the lower coupler 10, which is beneficial to simplifying the assembly process and improving efficiency.

[0047] like Figures 2 to 4 As shown, the fixing bracket 11 has a top wall and a circumferential wall 111 extending downward, and the bottom of the accommodating chamber 12 is open. After the lower coupler 10 is fixed to the fixing bracket 11, the wiring can be carried out. Since the card slot extends upward from the bottom end of the circumferential wall 111, one end of the strong wire 15 is bent upward. When the strong wire 15 is connected, the strong wire 15 can be inserted into the card slot at the same time, and the bent end of the strong wire 15 extends from the bottom of the accommodating chamber 12 to connect with the terminal 101. The operation is simple and convenient, which can reduce the difficulty of wiring. In addition, even if there are water drops on the wiring harness, when the water drops flow to the position of the card slot, they will be guided by the card slot so that the water drops fall vertically under the action of their own gravity, so that the water drops can be prevented from flowing to the control board, thereby improving the reliability of use.

[0048] Similarly, the second limiting portion 14 may also adopt a slot structure, so that the routing of the weak-wire 16 is also more convenient.

[0049] In other embodiments, the first limiting portion 13 may also be a limiting hole provided on the circumferential wall 111, and one end of the wiring harness may pass through the limiting hole and extend into the accommodating cavity 12 to connect with the terminal 101. Similarly, the second limiting portion 14 may also be in the form of a limiting hole.

[0050] In other embodiments, the first limiting portion 13 may also be a wire hook disposed on the circumferential wall 111. The wire hook may be disposed on the inner wall or the outer wall of the circumferential wall 111. The wire hook may be, for example, L-shaped, and the wire harness may be wound around the wire hook for one or several turns to achieve limiting. In this embodiment, the circumferential wall 111 is also provided with a hole, a notch, etc. for the wire harness to pass through or pass through, so that the wire harness can be connected to an external device. Similarly, the second limiting portion 14 may also be in the form of a wire hook.

[0051] It is understandable that the first limiting portion 13 and the second limiting portion 14 can be set in different forms, which is more conducive to distinguishing and arranging the strong wires 15 and the weak wires 16, avoiding installation errors, and improving assembly efficiency. Of course, the first limiting portion 13 and the second limiting portion 14 can also adopt the same structure.

[0052] In the solution where the fixing bracket 11 has the circumferential wall 111, the circumferential wall 111 can also prevent water from splashing into the lower coupler 10 when the water inlet pipe at the center of the lower coupler 10 falls off, thereby playing a water blocking role and avoiding safety accidents.

[0053] As a preferred embodiment of the present application, the first limiting portion 13 is disposed on one side of the fixing bracket 11 , and the second limiting portion 14 is disposed on an opposite side of the first limiting portion 13 .

[0054] By optimizing the arrangement of different limiting parts, the strong wires 15 and the weak wires 16 can be arranged relative to each other, which is beneficial to increase the isolation distance and improve the isolation effect.

[0055] like Figure 3 As shown, in one embodiment, three first limiting portions 13 are arranged on one side, and two second limiting portions 14 are arranged on the other side. The relative arrangement can avoid crowded arrangement of the wiring harness and enhance the isolation effect.

[0056] It can be understood that the number of the first limiting portions 13 and the second limiting portions 14 is not limited thereto and can be set according to actual needs.

[0057] As a preferred embodiment of the present application, the weak-wire 16 includes a first weak-wire 161 and a second weak-wire 162. The coupler is applied to a tea bar machine. The kettle of the tea bar machine is provided with a temperature detection element and a liquid level detection element. The temperature detection element is connected to the lower coupler 10 through the first weak-wire 161, and the liquid level detection element is connected to the lower coupler 10 through the second weak-wire 162.

[0058] Different types of detection elements can be connected to the lower coupler 10 through different weak wires 16, so that the tea bar machine has functions such as temperature detection and liquid level detection, thereby optimizing the performance of the product.

[0059] Furthermore, the tea bar machine is provided with a control panel, and the temperature detection element and the liquid level detection element are both weakly connected to the control panel.

[0060] The control panel can be used to obtain temperature information and liquid level information so as to perform relevant adjustment and control, which is conducive to meeting user needs and improving user experience.

[0061] As a preferred embodiment of the present application, a second opening 18 is provided on the top of the accommodating cavity 12, and a plurality of mounting portions 112 protruding inward are provided at the second opening 18. The lower coupler 10 is provided with a mating portion, and the mounting portion 112 and the mating portion are fixed by fasteners. The wiring terminal 101 extends into the accommodating cavity 12 through the second opening 18.

[0062] The lower coupler 10 and the fixing bracket 11 are fixed by fasteners and are securely installed, which can prevent the lower coupler 10 from loosening due to frequent picking up of the kettle, thereby improving the reliability of use; and the accommodating cavity 12 can provide waterproof protection, which can prevent the terminal 101 from contacting water and affecting the safety of the use of the lower coupler 10.

[0063] Specifically, Figure 2As shown, the mounting portion 112 is, for example, a boss, a first screw hole 113 is provided on the boss, a second screw hole is provided on the mating portion, and a fastener is, for example, a screw, by which the lower coupler 10 is locked on the fixing bracket 11, the firmness and stability of the installation can be ensured. The second opening 18 is provided between the plurality of mounting portions 112, and when the lower coupler 10 is installed, the wiring terminal 101 can be conveniently extended into the accommodating cavity 12, which is convenient for operation.

[0064] Preferably, three mounting portions 112 are provided and are evenly arranged along the circumferential direction, wherein an anti-foolproofing portion 19 is provided between two mounting portions 112 , and the first limiting portion 13 or the second limiting portion 14 and the anti-foolproofing portion 19 are provided on the same side.

[0065] By providing the fool-proof part 19, the installation position of the lower coupler 10 can be indicated, so that the strong current or weak current wiring can match the appropriate number of limit parts to avoid installation errors that affect the installation efficiency.

[0066] like Figure 2 As shown, the fool-proof portion 19 is, for example, a retaining wall that can cover a portion of the second opening 18, which can limit the terminal 101 from entering the accommodating cavity 12 from this position. In one embodiment, two second limiting portions 14 are provided on the side where the fool-proof portion 19 is located. When installing the lower coupler 10, it is only necessary to place the terminal 101 connected to the low-voltage wire 16 close to the second limiting portion 14 to determine the installation position of the lower coupler 10, thereby avoiding incorrect installation.

[0067] It is understandable that the fool-proof portion 19 may also adopt other structures, such as ribs, bumps, etc.

[0068] As a preferred embodiment of the present application, the coupler is applied to a tea bar machine, which is provided with a placement table 20 for placing a kettle, the placement table 20 is provided with a mounting port 21, the fixed bracket 11 is correspondingly arranged below the mounting port 21, the lower end of the lower coupler 10 extends into the mounting port 21 and is fixed to the fixed bracket 11, and a seal 22 is provided between the lower coupler 10 and the mounting port 21.

[0069] The present application applies the coupler to the tea bar machine, which can improve the arrangement of the wiring harness at the lower coupler 10 and the separation effect of strong and weak electricity. By further arranging the sealing member 22, it can prevent water from entering the accommodating cavity 12 from the matching gap between the lower coupler 10 and the mounting port 21, causing adverse consequences such as line short circuit and leakage, thereby improving the safety of product use and extending the service life.

[0070] like Figure 4 As shown, a sealing gasket is provided between the lower surface of the horizontal mounting surface of the lower coupler 10 and the placement platform 20 to prevent water from entering the accommodating cavity 12 from this position, thereby improving the safety and reliability of product use.
