Description

Technical Field

[0001] This invention belongs to the technical field of children's products, and specifically relates to an adjustable faucet extender. Background Technology

[0002] As families increasingly emphasize cultivating children's independent living habits, the demand for scenarios where young children can wash themselves independently is growing. Conventional household basin faucets typically have the water outlet located near the back of the basin, and the water outlet is relatively high. However, young children are too short and have limited arm span to reach the water outlet properly, making it easy for water to splash and wet their clothes, or for them to slip and fall due to excessive forward leaning. Therefore, child-friendly faucet extenders are widely used. These extenders mainly consist of an extender body and a baffle plate with an opening at the top. The extender body connects to the faucet, directing the water flow from the faucet through the front of the baffle plate, thus extending the water outlet and making it more accessible to children. However, due to variations in faucet placement and basin width, fixed-length faucet extenders cannot accurately guide the water flow to the appropriate area.

[0003] To address the aforementioned issues, an adjustable faucet extender is provided in the prior art. This extender has an adjustment plate located below the existing baffle plate. By moving the adjustment plate back and forth, the water outlet area of ​​the faucet extender can be adjusted. However, during use, due to the opening above the baffle plate, when the water flow rate is too high, splashing water is generated, which can easily wet the face and affect the use of the faucet extender. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an adjustable faucet extender. The technical problem to be solved by this invention is: how to prevent water from splashing out and affecting its use.

[0005] The objective of this invention can be achieved through the following technical solution: an adjustable faucet extender, comprising an extender body and a guide plate with an opening at the top, the guide plate being used to guide water flow out from the front end, the front end of the guide plate being provided with an extension plate that can move back and forth, the guide plate including a base plate, characterized in that the extension plate and the guide plate are connected by a hinge shaft, the distance from the hinge shaft to the front end face of the base plate is less than the distance from the hinge shaft to the inner bottom surface of the extension plate, so that the extension plate can rotate around the hinge shaft; When the extension plate is rotated upward, it covers the opening of the guide plate and can serve as an upper cover. When the extension plate rotates downward and is positioned below the guide plate, the portion of the extension plate that extends beyond the front end face of the guide plate forms an extension section.

[0006] This application features an extension plate that can move back and forth at the front end of a fixed-length guide plate, positioned below the guide plate. By moving the extension plate back and forth, the length of the extension at the front end can be adjusted, allowing the water outlet to be positioned in a suitable water-falling area to adapt to different usage environments. Furthermore, this application rotatably connects the extension plate and the guide plate via a hinge shaft, with the distance from the hinge shaft to the front end face of the base plate being less than the distance from the hinge shaft to the inner bottom surface of the extension plate. This prevents interference between the extension plate and the front end of the guide plate during rotation, providing sufficient space for the extension plate to rotate. The extension plate can rotate upwards around the hinge shaft and cover the opening of the guide plate as a top cover, preventing excessive water flow from splashing and wetting children's faces.

[0007] In the aforementioned adjustable faucet extender, the rear end of the extender plate is provided with a stop portion, which can abut against the lower surface of the guide plate. When the extender plate is flipped over and placed over the guide plate, the stop portion cooperates with the front end of the guide plate to prevent the extender plate from rotating and failing during use. When the extender plate is folded upward to form a top cover, the stop portion cooperates with the guide plate to form a closed water outlet, preventing water from splashing out from the front end of the guide plate.

[0008] In the aforementioned adjustable faucet extender, the guide plate further includes side plates on both sides, each side plate having a positioning protrusion. The extender plate has a sliding groove providing movement space for the extender plate. The sliding groove includes a first positioning part and a second positioning part located at the front and rear ends. The first positioning part and the second positioning part can respectively engage with the hinge shaft and / or the positioning protrusion. By engaging the first positioning part and the second positioning part with the positioning protrusion, the stability of the extender plate in the extended state and the extended plate in the top cover state is improved.

[0009] In the aforementioned adjustable faucet extender, when the extender plate covers the opening of the guide plate, the positioning protrusion engages with the first positioning part, and the extender plate and the guide plate cooperate to form a closed water outlet.

[0010] In the aforementioned adjustable faucet extender, two positioning protrusions are provided on the inner side of the slide groove. These two positioning protrusions respectively engage with the two end faces of the slide groove to form a first positioning part and a second positioning part. By positioning protrusions on the slide groove, movement of the positioning protrusions and the hinge shaft within the slide groove is prevented during use, thus improving stability during operation.

[0011] In the aforementioned adjustable faucet extender, the guide plate and the extension plate are inclined downwards to facilitate the downward flow of water.

[0012] In the aforementioned adjustable faucet extender, the connection between the positioning protrusion and the side plate is a rounded transition, and the end of the positioning protrusion has a guide arc surface. By setting the guide arc surface and the rounded transition, it is easy for the extender plate to fold upward or move backward to engage with the guide plate, reducing the difficulty of engagement and making it easier for children to operate.

[0013] In the aforementioned adjustable faucet extender, the length of the positioning protrusion is less than or equal to the thickness of the extension plate.

[0014] Compared with the prior art, the present invention has the following advantages: 1. This application achieves functional reuse of a single component through an extension plate structure that can be flipped around a hinge axis. This allows the extension plate to simultaneously possess two core functions: water outlet length adjustment and guide plate cover protection. The two working states can be quickly switched with a simple flipping action. While facilitating the adjustment of the guide plate extension length, it can also constrain the water flow to prevent splashing and reduce the impact of splashing.

[0015] 2. This application, through the cooperation structure of the slide groove, positioning protrusion, and hinge shaft, combined with the first positioning part and the second positioning part set at both ends of the slide groove, can achieve precise and reliable snap-fit ​​positioning for both the cover protection and water extension states of the extension plate. This effectively avoids problems such as displacement, slippage, and shaking of the extension plate during product use, and ensures the stability of the structure under different working states.

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0019] like Figure 1 and Figure 2 As shown, an adjustable faucet extender includes an extender body 1 and a guide plate 2. The extender body 1 has a mounting hole 1a at the top and a water outlet 1b at the front end. The guide plate 2 is located below the extender body 1 and its rear end is connected to the extender body 1. Its front end has a water outlet 4. The guide plate 2 has an opening 2a at the top, and the rear end of the opening 2a is attached to the bottom surface of the extender body 1. The side plates 2d on both sides of the guide plate 2 have a hinge shaft 2b and a positioning protrusion 2c at the front end. An extension plate 3 is covered above the opening 2a of the guide plate 2. The side of the extension plate 3 has a sliding groove 3c. The guide plate 2 and the extension plate 3 are U-shaped and cooperate with each other. The two sides of the extension plate 3 have sliding grooves 3c that can cooperate with the hinge shaft 2b and the positioning protrusion 2c. The two ends of the sliding groove 3c have a first positioning part 3c1 and a second positioning part 3c2.

[0020] It is worth mentioning that, in the anti-splash state, the extension plate 3 covers the opening 2a of the guide plate 2. The rear end of the extension plate 3 is provided with abutment part 3b. The end face of abutment part 3b cooperates with the front face of the guide plate 2 to form a closed water outlet 4. The hinge shaft 2b and the positioning protrusion 2c are both located at the front end of the guide plate 2 and are respectively engaged with the first positioning part 3c1 and the second positioning part 3c2. Specifically, the hinge shaft 2b is engaged with the second positioning part 3c2, and the positioning protrusion 2c is engaged with the first positioning part 3c1.

[0021] like Figure 3 and Figure 4 As shown, when the faucet extender is in the first extended state, the extension plate 3 is located below the guide plate 2 and is attached to the outer side wall of the guide plate 2. The part of the front end of the extension plate 3 that extends beyond the end face of the guide plate 2 is the extension part 3a. The hinge shaft 2b is engaged with the first positioning part 3c1, and the positioning protrusion 2c is engaged with the second positioning part 3c2.

[0022] like Figure 5 and Figure 6 As shown, when the faucet extender is in the first extended state, the extension plate 3 is located below the guide plate 2 and is attached to the outer side wall of the guide plate 2. The part of the front end of the extension plate 3 that extends beyond the end face of the guide plate 2 is the extension part 3a, and the part located below the guide plate 2 and abutting against it is the abutting part 3b. The hinge shaft 2b is engaged with the second positioning part 3c2, and the positioning protrusion 2c is separated from the slide groove 3c.

[0023] likeFigure 4 and Figure 6 As shown, the inner side of the slide groove 3c is provided with two positioning protrusions 3c3, which cooperate with the two ends of the slide groove 3c to form the first positioning part 3c1 and the second positioning part 3c2.

[0024] like Figure 7 As shown, the extender body 1, the guide plate 2, and the extension plate 3 are arranged sequentially along the water flow direction. The top of the extender body 1 is connected to the water outlet 1b of the faucet. The front end of the extender body 1 has an opening 2a for water to flow out. The hinge shaft 2b is located at the front end of the guide plate 2. Furthermore, the distance from the center of the hinge shaft 2b to the front end face of the bottom plate of the guide plate 2 is less than the distance from the hinge shaft 2b to the bottom surface of the extension plate 3. In addition, the guide plate 2 and the extension plate 3 of this application are inclined downwards.

[0025] In summary, this application, as a faucet extender, is mainly fixedly connected to the faucet through the mounting hole 1a at the top of the extender body 1. The water flows sequentially through the opening 2a at the front end of the extender body 1 and the guide plate 2, and finally flows out through the outlet 4 at the front end of the guide plate 2. In order to facilitate the observation of the water flow in the guide plate 2, enhance the fun, and avoid the problem of bacteria growth in the closed cavity and difficulty in cleaning, a guide plate 2 with an opening 2a at the top is adopted. However, due to the different widths of sinks and the different positions of faucets in different households, and the different areas that children of different heights can reach, these influencing factors will cause deviations in the water drop area. Therefore, the conventional fixed guide plate 2 cannot meet the needs of use in different environments. To solve the above problems, this application adds a hinge shaft 2b and a positioning protrusion 2c to the front end of the existing guide plate 2 to realize the adjustment of the length of the extension plate 3. Through the cooperation of the positioning protrusion 2c and the abutment part 3b at the rear end of the extension plate 3, the extension plate 3 is prevented from rotating during use, which would prevent the water flow from flowing to the predetermined water drop area.

[0026] Based on this, since children cannot accurately control the water flow and the force of the switch when using water, the water flow rate is easily too fast and the flow rate is too large. In order to solve the above problems, this application, based on the rotatable connection between the guide plate 2 and the extension plate 3 through the hinge shaft 2b, also makes the distance from the hinge shaft 2b to the bottom end face of the guide plate 2 less than the distance from the hinge shaft 2b to the inner bottom face of the extension plate 3, so as to provide sufficient room for the rotation of the extension plate 3 and avoid interference between the front end of the guide plate 2 and the bottom face of the extension plate 3. By folding the extension plate 3 upward to form a top cover, and making the abutting part 3b of the extension plate 3 cooperate with the front end face of the guide plate 2 to form a closed water outlet 4, the splashing water inside the guide plate 2 is blocked from splashing out.

[0027] It is worth mentioning that the extension plate 3 of this application has a sliding groove 3c on its side, which provides sufficient space for the reciprocating movement of the extension plate 3. A positioning protrusion 3c3 is provided on the inner side of the sliding groove 3c. The positioning protrusion 3c3 and the end faces of the two ends of the sliding groove 3c cooperate to form a first positioning part 3c1 and a second positioning part 3c2, so that the extension plate 3 is engaged with the hinge shaft 2b and the positioning protrusion 2c, which prevents the extension plate 3 from shaking during use. Furthermore, by arranging the positioning protrusion 2c and the hinge shaft 2b in sequence along the water flow direction, the positioning protrusion 2c is prevented from engaging with the extension plate 3 during rotation, which would increase the difficulty of opening.

[0028] Furthermore, the front end of the positioning protrusion 2c of this application is an arc end face, and there is an arc transition between the positioning protrusion 2c and the side wall of the guide plate 2. The length of the positioning protrusion 2c is less than the thickness of the extension plate 3, which facilitates the separation of the positioning protrusion 2c from the first positioning part 3c1 or the second positioning part 3c2, making it easier for children to operate and reducing the difficulty of use for children.
