Device for Preventing a Faucet from Leaking Water and Flowing Back

The present application relates to the technical field of faucet attachments, and in particular to a device for preventing a faucet from leaking water and flowing back.

Conventional bathtub faucets often leave a gap between the faucet body and the bathroom wall. This gap can be unsightly and allow water to seep behind the faucet, leading to mold growth, mildew, and potential water damage to the wall. Existing solutions, such as caulking, can be difficult to install and maintain, requiring periodic reapplication. This application addresses these shortcomings by providing a device that effectively prevents the faucet from leaking water and flowing back at the faucet-wall interface.

The present disclosure aims to provide a device for preventing a faucet from leaking water and flowing back to address problems that water is easy to seep into walls when current bathtub faucets are used.

To achieve above objectives, the present disclosure adopts following technical solutions. In some embodiments of the present disclosure, a device for preventing a faucet from leaking water and flowing back is provided, including an outer cover and an inner lining member, and the inner lining member is provided in the outer cover. Herein the outer cover is configured to cover a wall at a back end of the faucet to prevent water from flowing back, the inner lining member is provided with a plug hole for a water pipe to be plugged in, and the liner lining member is formed with a waterproof section on an outside of the plug hole to prevent water from flowing back into the wall.

Preferably, the outer cover and the inner lining member are both circular, a center of the outer cover is provided with a faucet holding slot for accommodating a tail of the faucet, and the inner lining member is provided with a corresponding avoiding slot.

Preferably, an edge of the outer cover is circumferentially outwardly and inwardly provided with a waterproof slope and an edge of the inner lining member is provided with a corresponding avoiding slope.

Preferably, the device further includes an annular washer, the inner lining member is provided with an annular step on the outside of the plug hole, and the annular washer is configured to be sleeved on the water pipe to prevent water from flowing back.

Preferably, the outer cover is made of stainless steel for longevity.

Preferably, the inner lining member is made of plastic material.

The present disclosure has at least following beneficial effects and advantages. The device for preventing the faucet from leaking water and flowing back of the present disclosure, the outer cover is used to cover the wall at the back end of the faucet, thus preventing water from flowing back into the wall. The liner lining member is set in the outer cover on which the plug hole is set for the water pipe to be plugged in. In actual use, the plug hole is sleeved on the outer wall of the water pipe to avoid water flowing to the wall through the water pipe, thus forming the waterproof section on the outer side of the plug hole to prevent water from flowing back into the wall through the water pipe, thereby realizing effective shielding and waterproofing of the wall at the back end of the bathtub faucet.

The present disclosure relates to a device for preventing a faucet from leaking water and flowing back, for covering the wall at the back end of the faucet and preventing water from flowing back. Specific embodiments of the present disclosure will be described in detail below in conjunction with accompanying drawings.

As shown into, in some embodiments of the present disclosure, a device for preventing a faucet from leaking water and flowing back is provided, including an outer coverand an inner lining member. The outer coveris configured to cover a wall at a back end of the faucet to prevent water from flowing back to the wall, and the inner lining memberis provided in the outer cover. The inner lining memberis provided with a plug holefor a water pipe to be plugged in, and in actual use, the plug holeis sleeved on an outer wall of the water pipe to avoid water flowing to the wall through the water pipe, thus a waterproof section is formed on an outside of the plug hole to prevent water from flowing back into the wall.

In specific embodiments, as shown into, the outer coverand the inner lining memberare both designed as circular, and such shape can better fit shapes of most faucets and installation environments. A center of the outer coveris provided with a faucet holding slotfor accommodating a tail of the faucet, so that the faucet and the wall can be covered up without leaving a gap. And accordingly, the inner lining memberprovided with a corresponding avoiding slotto avoid the faucet holding sloton the outer cover, so that entire device can be installed smoothly.

To further enhance waterproof effect, an edge portion of the outer coveris designed with a waterproof slope, which is a slope structure that can guide water to avoid water seeping into the wall. And meanwhile, an edge of the inner memberis correspondingly provided with an avoiding slopeto ensure a close fit between the inner lining memberand the outer cover.

Moreover, the device for preventing the faucet from leaking water and flowing back of the present disclosure further includes an annular washer. As shown inand, the annular washeris provided on an annular stepon the outside of the plug holeof the inner lining member. When the water pipe is plugged into the plug hole, the annular washerwill be tightly sleeved on the water pipe, and due to annular the washer has a certain degree of scalability, thus further preventing water from flowing back from the water pipe into the wall.

In some embodiments, the outer coveris made of stainless steel, which has corrosion and abrasion resistance properties, and can ensure that the outer coverstill maintains good appearance and functionality after long-term used in a humid environment. And in some other embodiments, the inner lining memberis made of plastic material, which on the one hand, can be used for a long period of time, and on the other hand, portions outside of the water pipe is all covered, thereby can prevent water from flowing back.

In summary, the device for preventing the faucet from leaking water and flowing back of the present disclosure, through a combination designs of the outer cover and the inner lining member and with assistance of the annular washer, thereby realizing effective shielding and waterproofing of the wall at the back end of the faucet. And meanwhile, by rational selection of materials, durability and economy of the device are ensured.

Obviously, described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art shall fall within the scope of protection of the present invention.
