Description

Technical Field

[0001] This utility model belongs to the field of faucet technology, specifically relating to a faucet that prevents scalding. Background Technology

[0002] A faucet is a common name for a water valve, a switch used to control the flow of water. They are ubiquitous in daily life. With societal development, faucet styles have become increasingly diverse, typically including a body, a spout, and a handle. Most faucets also have the function of adjusting the water flow and the temperature of the water. The water flow is controlled by swinging the handle, and the mixing ratio of hot and cold water is adjusted by turning the handle.

[0003] Adults can adjust the water temperature to a suitable level using the handle, but children and the elderly may get scalded when doing so. Children, unable to control the force, may turn the handle all the way to the end or to a position where the water is too hot. The elderly, with diminished sensitivity to temperature, may not be able to perceive whether the water temperature will cause burns. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, this utility model provides a faucet with a limiting structure to limit the maximum rotation angle of the handle according to requirements.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a scald-proof faucet, comprising a body and a handle, wherein the body comprises a front and a back side arranged opposite to each other, the handle is disposed on the front side, the handle is provided with an abutting end, the front side is provided with a sliding cavity extending towards the back side, the sliding cavity is provided with a sliding member, the side of the sliding member away from the back side is provided with a limiting end, the limiting end is provided with a limiting protrusion, the side wall of the sliding member is provided with a limiting groove, the limiting groove is provided with a limiting block, a spring is provided between the limiting block and the bottom of the limiting groove, the inner wall of the sliding cavity is provided with a limiting hole, the outer wall of the body is provided with an elastic arm, one end of the elastic arm is fixed to the body, and the other end is provided with a release end aligned with the limiting hole, the height of the release end protruding from the elastic arm is greater than or equal to the height of the limiting hole along its own axial direction.

[0006] The flexible arm can be fixed to the main body by welding or bolting.

[0007] With the above solution, when used by adults, the limiting end is located inside the sliding cavity. At this time, the limiting protrusion and the cavity opening on the front of the sliding cavity form a limit, allowing the handle to swing and rotate freely, making it convenient for adults to adjust the temperature according to their actual needs. At this time, the limiting block abuts against the inner wall of the sliding cavity under the action of the spring.

[0008] When children and the elderly need to use the device, adults apply force to the limiting protrusion, causing the limiting end and the sliding component to move away from the opposite side. This gradually disengages the limiting end from the sliding cavity until the limiting block, under the action of the spring, inserts into the limiting hole. At this point, the limiting block is simultaneously located in the limiting groove and the limiting hole, keeping the sliding component and the sliding cavity relatively fixed. After the handle is rotated and moved to a certain angle, the abutting end abuts against the limiting end, limiting the maximum rotation angle of the handle and thus controlling the maximum water temperature, preventing children or the elderly from being scalded.

[0009] When the child or elderly do not need to use it, the adult applies force to the two elastic arms with one hand, so that the release end applies force to the limiting block, so that the limiting block completely disengages from the limiting hole. The other hand pushes the limiting end, so that the limiting end and the sliding part move towards the opposite side, until the limiting protrusion and the sliding cavity are located at the front opening to form a limit.

[0010] As a further feature of this utility model, the sliding cavity is provided with a notch at the cavity opening on the front for the insertion of the limiting protrusion. The depth of the notch along the extension direction of the sliding cavity is greater than or equal to the thickness of the limiting protrusion along the extension direction of the sliding member. An inclined surface or a stepped surface is provided between the bottom of the notch and the outer wall of the main body.

[0011] Using the above solution, when the limiting end is not needed, the limiting protrusion is located within the notch, ensuring that the limiting protrusion does not protrude from the front and that adults will not come into contact with the limiting protrusion when turning the handle, thus improving the user experience. The presence of the inclined surface or stepped surface facilitates adults in applying force to the limiting protrusion.

[0012] As a further feature of this utility model, the limiting groove is a cylindrical groove, the limiting block is cylindrical, and the side wall of the limiting block facing the inner wall of the limiting groove and the bottom wall of the limiting block away from the spring are connected by a guide surface. The guide surface is a frustum-shaped structure that converges on the side away from the spring.

[0013] Using the above scheme, the shape of the limiting groove and the limiting block makes the spring more stable under force, and the frustum-shaped guide surface makes it easy for the limiting block to enter or leave the limiting hole.

[0014] As a further feature of this invention, the elastic arm is plate-shaped.

[0015] By adopting the above solution, the contact area is increased, making it easier for adults to press the elastic arm and providing a more comfortable operating experience.

[0016] As a further feature of this invention, the sliding cavity is a through cavity with both ends connected.

[0017] The above solution prevents water droplets that splash into the sliding cavity during washing from accumulating inside.

[0018] As a further feature of this utility model, the main body is provided with two sliding cavities, and the handle is located between the two sliding cavities.

[0019] Using the above solution, the actual connection positions of the hot and cold water pipes may differ from the preset positions. The two sliding cavities allow users to easily place the limiting end on the side that adjusts the hot water temperature according to the actual connection position. Depending on the design, there can be one, two, or more abutment ends.

[0020] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

[0025] Specific embodiments of this utility model are shown in the accompanying drawings.

[0026] A scalding-proof faucet includes a main body 1 and a handle 2. The main body 1 includes a front side 11 and a back side 12 arranged opposite to each other. The handle 2 is located on the front side 11. The front side 11 has a sliding cavity 13 extending towards the back side 12. A sliding member 3 is provided in the sliding cavity 13. A limiting groove 31 is provided on the side wall of the sliding member 3. A limiting block 4 is provided in the limiting groove 31. A spring 5 is provided between the limiting block 4 and the bottom of the limiting groove 31. A limiting end 32 is provided on the side of the sliding member 3 away from the back side 12. An abutment end 21 is provided on the handle 2. A limiting hole 14 is provided on the inner wall of the sliding cavity 13. A limiting protrusion 33 is provided on the limiting end 32. A notch 15 for the limiting protrusion 33 to be inserted is provided at the cavity opening of the sliding cavity 13 located on the front side 11. The depth of the notch 15 along the extension direction of the sliding cavity 13 is equal to the thickness of the limiting protrusion 33 along the extension direction of the sliding member 3. An inclined surface 16 is provided between the bottom of the notch 15 and the outer wall of the main body 1. The outer wall of the main body 1 is provided with an elastic arm 6. One end of the elastic arm 6 is fixed to the main body 1, and the other end is provided with a release end 61 for aligning with the limiting hole 14. In this embodiment, the elastic arm 6 is fixed to the main body 1 by bolts. The height of the release end 61 protruding from the elastic arm 6 is equal to the height of the limiting hole 14 along its own axial direction.

[0027] When used by adults, the limiting end 32 is located inside the sliding cavity 13. At this time, the limiting protrusion 33 and the notch 15 form a limit, allowing the handle 2 to swing and rotate freely, making it convenient for adults to adjust the temperature according to their actual needs. At this time, the limiting block 4 abuts against the inner wall of the sliding cavity 13 under the action of the spring 5.

[0028] When used by children and the elderly, adults apply force to the limiting protrusion 33, causing the limiting end 32 and the sliding member 3 to move away from the reverse side 12. This gradually disengages the limiting end 32 from the sliding cavity 13 until the limiting block 4 is inserted into the limiting hole 14 under the action of the spring 5. At this point, the limiting block 4 is simultaneously located in the limiting groove 31 and the limiting hole 14, keeping the sliding member 3 and the sliding cavity 13 relatively fixed. After the handle 2 rotates and moves a certain angle, the abutting end 21 abuts against the limiting end 32, which limits the maximum rotation angle of the handle 2, thereby controlling the maximum water temperature and preventing children or the elderly from being scalded.

[0029] When the child or elderly do not need to use the device, an adult applies force to the two elastic arms 6 with one hand, causing the release end 61 to apply force to the limiting block 4, completely disengaging the limiting block 4 from the limiting hole 14. The other hand pushes the limiting end 32, moving it and the sliding member 3 towards the reverse side 12 until the limiting protrusion 33 and the notch 15 form a limit, ensuring that the limiting protrusion 33 does not protrude from the front side 11. This prevents contact between the limiting protrusion 33 and the adult when turning the handle 2, improving the user experience. The inclined surface 16 facilitates the adult applying force to the limiting protrusion 33.

[0030] The limiting groove 31 is a cylindrical groove, and the limiting block 4 is cylindrical. The side wall of the limiting block 4 facing the inner wall of the limiting groove 31 and the bottom wall of the limiting block 4 away from the spring 5 are connected by a guide surface 41. The guide surface 41 is a frustum-shaped structure on the side away from the spring 5. The shapes of the limiting groove 31 and the limiting block 4 make the spring 5 more stable under force, and the frustum-shaped guide surface 41 facilitates the entry or exit of the limiting block 4 into the limiting hole 14.

[0031] The elastic arm 6 is plate-shaped. This increases the contact area, making it easier for adults to press the elastic arm 6 and providing a more comfortable operating experience.

[0032] The sliding cavity 13 is a through cavity with both ends open. In actual use, the distance from the opening of the sliding cavity 13 away from the front 11 to the ground is less than the distance from the opening of the sliding cavity 13 located on the front 11 to the ground. In this embodiment, the sliding cavity 13 is provided with an inclined drainage surface 131 at the opening away from the front 11 to prevent water droplets splashed into the sliding cavity 13 during washing from accumulating in the sliding cavity 13.

[0033] The main body 1 has two sliding chambers 13, and the handle 2 is located between the two sliding chambers 13. In actual installation, the connection positions of the hot and cold water pipes may not be consistent with the preset positions. The two sliding chambers 13 make it convenient for people to set the limiting end 32 on the side for adjusting the hot water temperature according to the actual connection position. Depending on the design, the abutment end 21 can be one, two or more. This embodiment has two mirror-shaped abutment ends 21.

[0034] This utility model is not limited to the specific embodiments described above. Those skilled in the art can implement this utility model using other specific embodiments based on the content disclosed in this utility model. Any simple changes or modifications made to the design structure and concept of this utility model will fall within the protection scope of this utility model.
