Description

Technical Field

[0001] This utility model relates to the field of electric heating equipment technology, and in particular to an electric water faucet. Background Technology

[0002] Electric water faucets are favored by the market because they can quickly heat and provide hot water. They generally have a water tank and an installation cavity that are isolated from each other. The main electrical components are assembled in the installation cavity. The main electrical components include the heating element and the circuit board, which are connected by quick-connect terminals for easy assembly and disassembly. The heating element of the heating element passes through the partition and extends into the water tank. This structure inevitably makes the installation cavity a high-temperature and humid environment, which has a corrosive effect on the exposed parts of the electrical components, especially the terminals, reducing their service life and posing certain safety hazards. Replacement of parts is required after long-term use, which is inconvenient. Utility Model Content

The electrical components include at least a PCB circuit board 4 and an electric heating component that are electrically connected in sequence, and the functional end of the electric heating component extends at least partially into the water tank. The PCB circuit board 4 and the electric heating component are electrically connected by a waterproof plug 5.

In the assembled state, the second rubber sleeve 9 extends at least partially into the first rubber sleeve 8 and forms a sealing structure.

[0034] Based on the above technical solution, the electric water faucet includes a main body 1, a PCB circuit board 4, an electric heating component, and a waterproof plug 5. The waterproof plug 5 includes a male terminal 6, a female terminal 7, a first rubber sleeve 8, and a second rubber sleeve 9. The second rubber sleeve 9 and the first rubber sleeve 8 form a sealing structure, which can prevent moisture and dampness from the electrical component connection terminals in the installation cavity of the main body 1, reduce the aging rate of the connection terminals and improve the service life, and effectively improve the safety of the whole machine. At the same time, the plug-in structure facilitates the assembly and disassembly of electrical components.

[0035] In a preferred embodiment, specifically as follows: Figures 6 to 8 As shown, one side of the first rubber sleeve 8 has a groove 10 for inserting the second rubber sleeve 9. The groove 10 is generally square, and one side has an irregular shape 19. The end of the second rubber sleeve 9 facing the first rubber sleeve 8 is shaped to fit the groove 10, so that the second rubber sleeve 9 can only be inserted into the first rubber sleeve 8 in a limited direction, thereby achieving the purpose of preventing mistake-proofing. Furthermore, the second rubber sleeve 9 and the groove 10 are press-fitted to achieve a better sealing effect. Furthermore, in this embodiment, the irregular shape 19 is an arc surface, but it can also be a trapezoid, triangle, cone, or other structures, and is not limited to this. Furthermore, the first rubber sleeve 8 is plastic-molded on the outside of the male terminal 6, and the second rubber sleeve 9 is plastic-molded on the outside of the female terminal 7.

[0036] In a preferred embodiment, specifically as follows: Figure 2 As shown, the heating assembly includes an electric heating element 2 and a power regulating component 3 electrically connected to each other. The electric heating element 2 extends at least partially into the water tank, and the end of the male terminal 6 opposite to the female terminal 7 is electrically connected to the power regulating component 3. Furthermore, the power regulating component 3 is a silicon controlled rectifier (SCR), but it can also be other transistors, and is not limited to this.

[0037] In a preferred embodiment, combined with Figures 1 to 5As shown, the main body 1 includes an inner liner 11, an outer shell 12 fitted outside the inner liner 11, a water outlet assembly 13 installed on the upper end of the inner liner 11, an upper cover 14 fitted outside the water outlet assembly 13, and a decorative ring 15 fitted on the outer peripheral wall of the water outlet assembly 13 and located between the upper cover 14 and the outer shell 12.

The irregularly shaped sealing ring 16 abuts against the outer wall of the inner liner 11, the inner wall of the outer shell 12, the outer wall of the water outlet assembly 13, and the inner wall of the decorative ring 15, so that external clean water or water mist is difficult to enter the machine body from the assembly gaps of each component. Compared with the existing sealing rings, it has a better sealing effect.

[0038] As a further preferred embodiment, the irregular sealing ring 16 is cylindrical in shape, and its upper edge is configured as a first arc surface structure 17 protruding inward to abut against the outer wall of the water outlet assembly 13 and the inner wall of the decorative ring 15, and its lower edge is configured as a second arc surface structure 18 protruding outward to abut against the outer wall of the inner liner 11 and the inner wall of the outer shell 12.

[0039] As a further preferred embodiment, combined with Figure 3 As shown, the outer wall of the upper edge of the inner liner 11 is concave in an annular shape, and forms part of the annular space between it and the inner wall of the outer shell 12. The outer wall of the water outlet assembly 13 forms an annular step structure at the upper edge of the inner liner 11. The annular step structure, the decorative ring 15, and the upper edge of the inner liner 11 form another part of the annular space. In the compressed state after assembly, the lower edge of the first arc surface structure 17 also abuts against the upper edge of the inner liner 11, resulting in a better sealing effect.

Specifically, the main body 1 includes an inner tank 11, an outer shell 12 fitted outside the inner tank 11, a water outlet component 13 installed on the upper end of the inner tank 11, and an upper cover 14 assembled outside the water outlet component 13. An irregularly shaped sealing ring 16 is embedded in the annular space formed by the inner tank 11, the outer shell 12, the water outlet component 13, and the upper cover 14. The irregularly shaped sealing ring 16 abuts against the outer wall of the inner tank 11, the inner wall of the outer shell 12, the outer wall of the water outlet component 13, and the inner wall of the upper cover 14, so that external clean water or water mist is difficult to enter the body from the assembly gaps of each component. Compared with the existing sealing ring, it has a better sealing effect.

[0043] As a further preferred embodiment, the irregular sealing ring 16 is cylindrical in shape, and its upper edge is configured as a first arc surface structure 17 protruding inward to abut against the outer wall of the water outlet assembly 13 and the inner wall of the upper cover 14, and its lower edge is configured as a second arc surface structure 18 protruding outward to abut against the outer wall of the inner liner 11 and the inner wall of the outer shell 12.

Furthermore, in the compressed state after assembly, the lower edge of the first arc surface structure 17 also abuts against the upper edge of the inner liner 11, resulting in a better sealing effect.
