Description

Technical Field

[0001] This utility model application relates to the field of faucet technology, specifically to an elbow-operated faucet. Background Technology

[0002] Faucets are key devices for controlling water flow and are widely used in homes, public facilities, and industrial sectors. Their core function is to regulate water volume and temperature via a valve core. Materials primarily include stainless steel, copper alloy, and plastic, balancing durability and hygiene. Based on operation, they can be categorized into knob-type, single-handle dual-control type, and sensor-type. The latter uses infrared technology for automatic opening and closing, effectively reducing contact contamination. Modern faucets also incorporate water-saving technologies, such as aerator designs that reduce water flow impact, decreasing water consumption by 30%-50%. In commercial settings, corrosion-resistant 304 stainless steel faucets are commonly found in the catering industry, while high-flow cast iron faucets are used in industrial applications to meet specific needs.

[0003] Chinese Patent Publication No. CN219062532U discloses a flip-type double-outlet faucet, including a base, an inlet pipe fixedly connected to the base, and outlet pipes respectively disposed at both ends of the base. The outlet pipes are equipped with switches. A connecting pipe is provided between the base and the outlet pipes. The inlet pipe, base, connecting pipe, and outlet pipes are connected in sequence. One end of the connecting pipe is fixedly connected to the inlet end of the outlet pipe, and the other end of the connecting pipe is rotatably connected to the base. A sealing element is provided between the connecting pipe and the base. A limiting spring is sleeved on the connecting pipe. A fixing nut is threadedly connected to the end of the base connected to the connecting pipe. The limiting spring is pressed between the end face of the base and the fixing nut. The flip-type outlet pipe can be achieved by rotating the connecting pipe and the base. The structure is simple and the flip-type is reliable. The fixing nut makes the outlet pipe stable after flipping and not easy to displace. Multiple sealing rings are provided on the connecting pipe to achieve a good sealing effect and reduce the leakage of the outlet pipe during the flip-type process.

[0004] The faucet in the aforementioned patent document filters impurities in the water by installing a filter screen inside the inlet pipe and connecting the top of the inlet pipe to the base via threads. However, the filter screen needs to be replaced or cleaned after a period of use, requiring the inlet pipe to be periodically removed from the base. Repeated disassembly and reassembly of the inlet pipe can easily cause wear on the threads, leading to loosening or even leakage at the connection between the inlet pipe and the base. Therefore, an elbow-operated faucet is proposed. Utility Model Content

[0005] To address the aforementioned issues, an elbow-operated faucet is provided. When the first threaded sleeve is rotated, it moves longitudinally through its threaded engagement with the base pipe. As the first threaded sleeve moves longitudinally along the central axis of the base pipe, the tapered surface at the top of the first threaded sleeve presses against the clamping rod via an arc-shaped inclined surface. At this time, the clamping rod rotates clockwise around the hinge point with the mounting base, and the end of the clamping rod away from the arc-shaped inclined surface clamps onto the valve body. This allows for quick assembly and disassembly of the base pipe and valve body, solving the problems of long assembly and disassembly cycles and inconvenient filter replacement.

[0006] To address the existing technical problems, this application provides an elbow-operated faucet, including a bottom pipe, a valve body disposed at the top of the bottom pipe, and a bend disposed at the top of the valve body. A filter screen is installed inside the top of the bottom pipe, and several mounting seats are fixed at equal intervals around the central axis on the outer wall of the top of the bottom pipe. A clamping rod for fixing the valve body is installed on the mounting seat. The clamping rod is hinged to the mounting seat, and an arc-shaped inclined surface is provided on the side of the bottom end of the clamping rod facing the bottom pipe. The bottom tube is fitted with a first threaded sleeve that can move longitudinally along its central axis. The first threaded sleeve is threadedly engaged with the bottom tube. The outer wall of the top of the first threaded sleeve is provided with a tapered surface that can be adapted to the arc-shaped inclined surface.

[0007] As one technical solution of this application, the bottom end of the valve body is provided with a mounting head, and the external thread of the mounting head is provided with slots equidistantly around the central axis. The top of the clamping rod is provided with a clamping head that can be adapted to the slot.

[0008] As one technical solution of this application, a slot is longitudinally provided at the bottom end of the mounting head; The top of the bottom tube is fixed with a plug that can be inserted into a slot.

[0009] As one technical solution of this application, a second sealing ring is installed inside the slot, and the top of the filter screen contacts the second sealing ring; The bottom tube has a first sealing ring inside, and the bottom of the valve body is in contact with the upper surface of the second sealing ring.

[0010] As one technical solution of this application, the bottom end of the bend is provided with a plug that can be inserted into the top of the valve body, and the bottom end of the bend is also fitted with a second threaded sleeve, the internal thread of the second threaded sleeve being threadedly engaged with the external thread of the valve body.

[0011] As one technical solution of this application, the plug is provided with a plurality of third sealing rings on its outer side, and the external threads of the third sealing rings are in contact with the inner wall of the valve body.

[0012] As one technical solution of this application, an air bubble generator is installed at the outlet end of the bend.

[0013] The advantages of this utility model application compared to the prior art are: When the first threaded sleeve is rotated, it can move longitudinally through its threaded engagement with the bottom tube. As the first threaded sleeve moves longitudinally along the central axis of the bottom tube, the tapered surface at the top of the first threaded sleeve presses against the clamping rod through the arc-shaped inclined surface. At this time, the clamping rod rotates clockwise around the hinge point with the mounting base, and the end of the clamping rod away from the arc-shaped inclined surface clamps onto the valve body. This enables quick assembly and disassembly of the bottom tube and valve body, solving the problems of long assembly and disassembly cycles and inconvenient filter replacement.

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] See Figures 1-7As shown, an elbow-operated faucet includes a base pipe 1, a valve body 3 disposed at the top of the base pipe 1, and a bent pipe 4 disposed at the top of the valve body 3. A filter screen 11 is installed inside the top of the base pipe 1. Several mounting seats 102 are fixed at equal intervals around the central axis on the outer wall of the top of the base pipe 1. A clamping rod 12 for fixing the valve body 3 is installed on the mounting seat 102. The clamping rod 12 is hinged to the mounting seat 102. An arc-shaped inclined surface 122 is provided on the side of the bottom end of the clamping rod 12 facing the base pipe 1. The bottom tube 1 is equipped with a first threaded sleeve 13 that can move longitudinally along its central axis. The first threaded sleeve 13 is threadedly engaged with the bottom tube 1. The outer wall of the top end of the first threaded sleeve 13 is provided with a tapered surface 131 that can be adapted to the arc-shaped inclined surface 122.

[0024] When the first threaded sleeve 13 is rotated, it can move longitudinally through its threaded engagement with the bottom tube 1. As the first threaded sleeve 13 moves longitudinally along the central axis of the bottom tube 1, the tapered surface 131 at the top of the first threaded sleeve 13 presses against the clamping rod 12 through the arc-shaped inclined surface 122. At this time, the clamping rod 12 rotates clockwise around the hinge point with the mounting base 102, and the end of the clamping rod 12 away from the arc-shaped inclined surface 122 clamps onto the valve body 3. This allows for quick assembly and disassembly of the bottom tube 1 and the valve body 3, solving the problems of long assembly and disassembly cycles for the bottom tube 1 and valve body 3, and inconvenient replacement of the filter screen 11.

[0025] See Figure 4 , Figure 5 and Figure 6 As shown, the bottom end of the valve body 3 is provided with a mounting head 31, and the external thread of the mounting head 31 is provided with slots 32 at equal intervals around the central axis; The top of the clamping rod 12 is provided with a clamping head 121 that can be adapted to the slot 32.

[0026] To ensure that the clamping rod 12 effectively fixes the valve body 3, a clamping head 121 is provided at the top of the clamping rod 12. When the clamping rod 12 rotates clockwise around the hinge point with the mounting base 102, the clamping rod 12 will drive the clamping head 121 to engage in the slot 32, so that the clamping rod 12 fixes the valve body 3 through the cooperation of the clamping head 121 and the slot 32.

[0027] See Figure 5 and Figure 6 As shown, the bottom end of the mounting head 31 has a slot 33 longitudinally formed; The top end of the bottom tube 1 is fixed with a plug 101 that can be inserted into the slot 33.

[0028] To ensure a stable connection between the bottom pipe 1 and the valve body 3, a slot 33 is longitudinally opened in the mounting head 31, and then the filter screen 11 at the top of the bottom pipe 1 is inserted into the slot 33, so that the bottom pipe 1 and the valve body 3 can be precisely connected, thereby improving the connection efficiency between the bottom pipe 1 and the valve body 3.

[0029] See Figure 4 , Figure 5 and Figure 6 As shown, a second sealing ring 34 is installed inside the slot 33, and the top of the filter screen 11 contacts the second sealing ring 34; The bottom tube 1 has a first sealing ring 103 inside its top end, and the bottom end of the valve body 3 is in contact with the upper end face of the second sealing ring 34.

[0030] To ensure the sealing between the bottom pipe 1 and the valve body 3, a second sealing ring 34 is installed in the slot 33, and a first sealing ring 103 is installed inside the bottom pipe 1. When the filter screen 11 is inserted into the slot 33, the top end of the filter screen 11 comes into close contact with the second sealing ring 34 under the clamping force of the clamping rod 12. At the same time, the bottom end of the mounting head 31 comes into close contact with the upper end face of the first sealing ring 103. This achieves an effective seal between the bottom pipe 1 and the valve body 3.

[0031] See Figure 1 and Figure 2 As shown, the bottom end of the bend 4 is provided with a connector 41 that can be inserted into the top of the valve body 3. The bottom end of the bend 4 is also fitted with a second threaded sleeve 5, and the internal thread of the second threaded sleeve 5 is engaged with the external thread of the valve body 3.

[0032] To achieve an effective connection between the bend 4 and the valve body 3, a plug 41 is installed at the bottom of the bend 4, and then the plug 41 is inserted into the valve body 3. Then, the second threaded sleeve 5 is rotated so that the second threaded sleeve 5 and the valve body 3 fix the bend 4 under the action of threaded engagement.

[0033] See Figure 3 and Figure 7 As shown, the connector 41 is fitted with several third sealing rings 42 on its outside, and the external threads of the third sealing rings 42 are in contact with the inner wall of the valve body 3.

[0034] To ensure an effective seal between the connector 41 and the valve body 3, several third sealing rings 42 are fitted around the outside of the connector 41. When the second threaded sleeve 5 fixes the bend 4, the downward pressure of the second threaded sleeve 5 will act on the third sealing rings 42 through the bend 4 and the connector 41, making the third sealing rings 42 in close contact with the inner wall of the valve body 3, thereby effectively preventing water leakage at the connection between the bend 4 and the valve body 3.

[0035] See Figure 1 and Figure 2As shown, an aerator 6 is installed at the outlet end of the bend 4.

[0036] The bubble generator 6 is fixedly installed at the output end of the bend 4. When water flows out of the bend 4 through the bubble generator 6, a large number of microbubbles are formed in the water. This not only achieves water conservation but also effectively suppresses water splashing through the buffering effect of the bubbles.

[0037] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
