[0019] The utility model relates to a device for preventing water from leaking back from a faucet, which is used for shielding the wall surface at the rear end of the faucet and preventing water from flowing back. The specific implementation mode of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 one Figure 4 As shown, the device for preventing water leakage from a faucet from flowing back comprises an outer cover 1 and an inner lining 2. The outer cover 1 is used to shield the wall at the rear end of the faucet, thereby preventing water from flowing back into the wall. The inner lining 2 is arranged in the outer cover 1, and a plug-in hole 21 for plugging in a water supply pipe is arranged on the inner lining 2. In actual use, the plug-in hole 21 is 21 It is sleeved on the outer wall of the water pipe to prevent water from flowing to the wall through the water pipe, thereby forming a waterproof part on the outside of the plug hole 21 to prevent water from flowing back into the wall through the water pipe.

[0021] In the specific implementation, Figure 2 one Figure 4As shown, the outer cover 1 and the inner lining 2 are both designed to be circular, and this shape can better adapt to the shape and installation environment of most faucets. A faucet receiving groove 11 is provided in the middle of the outer cover 1 to accommodate the tail of the faucet, so that the faucet and the wall can be shielded without leaving a gap. Correspondingly, a corresponding avoidance groove 22 is also provided on the inner lining 2 to avoid the faucet receiving groove 11 of the outer cover 1, so that the entire device can be installed smoothly.

[0022] In order to further enhance the waterproof effect, the edge of the outer cover 1 is designed with a waterproof slope 12, which can guide water and prevent water from seeping into the wall. At the same time, the edge of the lining 2 is also correspondingly provided with an avoidance slope 23 to ensure a close fit between the lining 2 and the outer cover 1.

[0023] Furthermore, the device for preventing faucet water leakage from flowing back further comprises an annular gasket 3. Figure 1 and Figure 2 As shown, the annular gasket 3 is arranged on the annular step 24 outside the plug hole 21 of the lining member 2. When the water pipe is inserted into the plug hole 21, the annular gasket 3 will be tightly sleeved on the water pipe, and the gasket has a certain elasticity, thereby further preventing water from flowing back from the water pipe into the wall.

[0024] In some embodiments, the outer cover 1 is made of stainless steel, which is corrosion-resistant and wear-resistant, and can ensure that the outer cover 1 maintains good appearance and function after long-term use in a humid environment. In other embodiments, the lining 2 is made of plastic. On the one hand, plastic can be used for a long time, and on the other hand, all parts outside the water pipe are blocked to prevent water backflow.

[0025] In summary, the device for preventing faucet leakage and backflow of the utility model realizes effective shielding and waterproofing of the rear end wall of the faucet through the combined design of the outer cover and the inner lining, and the assistance of the annular gasket. At the same time, the durability and economy of the device are ensured through the reasonable selection of materials.

[0026] Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.
