Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage equipment technology, and in particular to a single-cold water tap. Background Technology

[0002] In low-temperature environments, the internal water of a single-cold water faucet freezes and expands in volume, which can cause water pipe blockage and interfere with normal water use. Current technologies are insufficient to deal with this situation, and developing a single-cold water faucet that can better withstand low temperatures is crucial for the industry's development.

[0003] Existing single-cold-water faucets are prone to internal water freezing in low-temperature environments. This not only causes water pipe blockage, resulting in poor or even interrupted water flow, but may also damage the internal structure of the faucet due to the expansion of ice, reducing its lifespan. Therefore, we propose a single-cold-water faucet to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a single-cold water faucet that can solve the problem that the water inside the existing single-cold water faucet is very easy to freeze in low-temperature environments. This not only causes water pipe blockage, resulting in poor or even interrupted water flow, but may also damage the internal structure of the faucet due to the expansion of ice, thus reducing the service life of the faucet.

[0006] To solve the above-mentioned technical problems, this utility model provides a single cold water faucet, which adopts the following technical solution: it includes a faucet shell, an equipment cavity inside the faucet shell, a water outlet pipe integrally formed on the front of the faucet shell, the water outlet pipe having an upward curved structure, a water flow cavity inside the water outlet pipe, the water flow cavity being connected to the equipment cavity, a water-blocking baffle integrally formed between the water flow cavity and the equipment cavity, a first water outlet and a second water outlet of the same size arranged vertically on the water-blocking baffle, the first water outlet and the second water outlet being independent and not connected to each other, and a water-blocking shaft rotatably installed inside the equipment cavity, the water-blocking shaft being able to control the opening and closing of the first water outlet and the second water outlet respectively.

[0007] Optionally, a flow guide block is fixed inside the device cavity. The flow guide block is arranged vertically from top to bottom as a second flow guide layer, a first flow guide layer, and an initial flow guide layer. A vertical partition is provided inside the initial flow guide layer, which divides the internal space of the initial flow guide layer into a first flow channel and a second flow channel. The first flow channel and the second flow channel are independent of each other. A first flow guide notch is opened on the side of the initial flow guide layer facing the first flow guide layer, and the first flow guide notch is connected to the first flow channel. A second flow guide notch is opened on the side of the initial flow guide layer facing the second flow guide layer, and the second flow guide notch is connected to the second flow channel.

[0008] Optionally, a first water-blocking block and a second water-blocking block are integrally formed on the water-blocking shaft. Both the first water-blocking block and the second water-blocking block are fan-shaped protrusions. The first water-blocking block is located below the second water-blocking block. The top view projections of the first water-blocking block and the second water-blocking block do not overlap, and their fan-shaped orientations are staggered along the circumferential direction.

[0009] Optionally, the first water-blocking block is slidably fitted within the first flow guide layer along the circumferential direction, and the second water-blocking block is slidably fitted within the second flow guide layer along the circumferential direction. The second water-blocking block has a height difference structure, with one side of its height matching the height of the second flow guide layer, and the other side having a height lower than the matching height. The area of ​​the lower height forms a water flow avoidance groove. The water flow avoidance groove is used to avoid the water flow flowing out of the second flow channel through the second flow guide gap, so that the water flow can be guided to the first outlet through the water flow avoidance groove.

[0010] Optionally, the bottom of the second water-blocking block is provided with a complete base plate. When the water-blocking shaft drives the second water-blocking block to rotate in the circumferential direction to the second flow guide gap, the base plate can completely block the second flow guide gap, and the first flow guide layer provides a flow channel for the water flowing out of the second flow channel through the second flow guide gap.

[0011] Optionally, the first and second flow-guiding gaps are staggered along the circumferential direction of the flow-guiding block, and the fan-shaped orientation of the first and second water-blocking blocks corresponds to the positions of the first and second flow-guiding gaps to form two independent water flow control states.

[0012] Optionally, the faucet housing is coaxially positioned below the water-blocking shaft and is rotatably mounted with a connecting pipe via a threaded connection. A sealing ring is provided between the mating surface of the connecting pipe and the faucet housing to achieve a seal.

[0013] Optionally, a diversion plate is integrally formed directly below the equipment cavity. The diversion plate has the same angle, appropriate width, and corresponding position in the vertical direction as the vertical partition in the initial flow guiding layer, together forming a preliminary diversion and guiding structure for the water flow. A drain hole is provided at the lowest point of the water flow cavity inside the water outlet pipe. A water-blocking plug is installed in the drain hole by thread rotation.

[0014] Optionally, the end of the water-blocking shaft extends outside the faucet housing, and a rotary control handle is fastened to the extended end of the water-blocking shaft. The rotary control handle is used to drive the water-blocking shaft to rotate axially.

[0015] In summary, this utility model has at least one of the following beneficial effects: 1. By setting two independent first and second flow channels as water inlet channels, and combining them with flow guide blocks with first and second flow guide notches in the equipment cavity, as well as first and second water blocking blocks adapted to the notch positions, the water blocking shaft is driven to rotate by rotating the control head, so that the two flow channels can output water through the first and second water outlets respectively without interfering with each other. This achieves the purpose of switching to the other flow channel to output water normally when one flow channel is blocked, realizing the effect of independent operation and flexible switching of dual water flow in a single device, and improving the reliability and continuous water supply capacity of the faucet under complex working conditions.

[0016] 2. By adopting a slope structure design for the water flow chamber of the water outlet pipe and opening a drain hole at the lowest point of the water flow chamber through which a water-blocking plug is installed by thread, the water accumulated in the chamber is allowed to collect along the slope and be completely discharged through the drain hole. This effectively prevents residual water from freezing and clogging in low-temperature environments, ensuring the normal use of the faucet in cold weather and solving the problem of traditional faucets being unable to dispense water due to water freezing.

[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0021] Example 1, refer to Figure 1-4 In this embodiment, to address the problem that existing single-cold-water faucets are prone to internal water freezing in low-temperature environments, which not only causes water pipe blockage, resulting in poor or even interrupted water flow, but may also damage the internal structure of the faucet due to ice expansion, reducing the faucet's lifespan, this utility model discloses a single-cold-water faucet. The faucet includes a faucet housing 1, which has an internal equipment cavity 12. A water outlet pipe 13 is integrally formed on the front of the faucet housing 1, and the water outlet pipe 13 has an upward-curving arc shape. A water flow chamber 131 is formed inside the water outlet pipe 13, and the water flow chamber 131 is connected to the equipment cavity 12. A water-blocking baffle 14 is integrally formed between the water flow chamber 131 and the equipment cavity 12. The water-blocking baffle 14 has a first water outlet 141 and a second water outlet 142, which are arranged vertically and are of the same size. The first water outlet 141 and the second water outlet 142 are independent of each other. Furthermore, they are not connected. Inside the equipment cavity 12, a water-blocking shaft 2 is rotatably installed along the axial direction. The water-blocking shaft 2 can control the opening and closing of the first water outlet 141 and the second water outlet 142 respectively. Through the equipment cavity 12 inside the faucet shell 1, there is an integrally formed arc-shaped water outlet pipe 13 that curves upwards at the front. A water-blocking baffle 14 with the first water outlet 141 and the second water outlet 142 is provided between the water flow cavity 131 and the equipment cavity 12. With the help of the rotatable water-blocking shaft 2, the first water outlet 141 and the second water outlet 142 are controlled respectively, thus achieving the purpose of structural integration and water flow control.

[0022] Inside the equipment cavity 12, a flow guide block 3 is fixedly installed. The flow guide block 3 is arranged vertically from top to bottom as a second flow guide layer 33, a first flow guide layer 32, and an initial flow guide layer 31. The initial flow guide layer 31 has a vertical partition 311 that divides the internal space of the initial flow guide layer 31 into a first flow channel 3111 and a second flow channel 3112. The first flow channel 3111 and the second flow channel 3112 are independent of each other. A first flow guide notch 321 is opened on the side of the initial flow guide layer 31 facing the first flow guide layer 32. The first flow guide notch 321 and the first flow channel 3111 are connected. The initial flow guide layer 31 is connected to the second flow guide layer 33. A second flow guide gap 331 is provided on the side of the initial flow guide layer 31 facing the second flow guide layer 33. The second flow guide gap 331 is connected to the second flow channel 3112. By fixing the flow guide block 3, which consists of the second flow guide layer 33, the first flow guide layer 32, and the initial flow guide layer 31 and has a vertical partition 311, inside the equipment cavity 12, the independent first flow channel 3111 and the second flow channel 3112 are separated by the vertical partition 311. The flow channels are connected by the flow guide gaps of different flow guide layers, so as to achieve the purpose of orderly diversion of water flow between the layers without interference.

[0023] The water-blocking shaft 2 is integrally formed with a first water-blocking block 21 and a second water-blocking block 22. Both the first water-blocking block 21 and the second water-blocking block 22 are fan-shaped protrusions. The first water-blocking block 21 is located below the second water-blocking block 22. The top view projections of the first water-blocking block 21 and the second water-blocking block 22 have no overlapping area. The fan-shaped orientations of the two are staggered along the circumferential direction. By integrally forming the first water-blocking block 21 and the second water-blocking block 22 with fan-shaped protrusions that have no overlapping area in their top view projections and whose fan-shaped orientations are staggered along the circumferential direction on the water-blocking shaft 2, the purpose of independently controlling the opening and closing of the first water outlet 141 and the second water outlet 142 is achieved.

[0024] The first water-blocking block 21 slides in the first flow-guiding layer 32 along the circumferential direction, and the second water-blocking block 22 slides in the second flow-guiding layer 33 along the circumferential direction. The second water-blocking block 22 has a height difference structure. The height of one side is adapted to the height of the second flow-guiding layer 33, and the height of the other side is lower than the adapted height. The area of ​​the lower height forms a water flow avoidance groove 221. The water flow avoidance groove 221 is used to avoid the water flow from the second flow channel 3112 through the second flow-guiding gap 331, so that the water flow can be guided to the first outlet 141 through the water flow avoidance groove 221. By allowing the first water-blocking block 21 to slide in the first flow-guiding layer 32 along the circumferential direction, and the second water-blocking block 22 to slide in the second flow-guiding layer 33, and the second water-blocking block 22 to have a height difference structure to form the water flow avoidance groove 221, the purpose of guiding the water flow from the second flow channel 3112 to the first outlet 141 through the avoidance groove is achieved, realizing flexible guidance and multi-path flow of water.

[0025] The bottom of the second water-blocking block 22 is provided with a complete base plate 222. When the water-blocking shaft 2 drives the second water-blocking block 22 to rotate in the circumferential direction to the second flow guide gap 331, the base plate 222 can completely block the second flow guide gap 331, and the first flow guide layer 32 provides a flow channel for the water flowing out of the second flow channel 3112 through the second flow guide gap 331. By providing a complete base plate 222 at the bottom of the second water-blocking block 22, when the water-blocking shaft 2 drives it to rotate to the second flow guide gap 331, the base plate 222 can completely block the gap. At the same time, the first flow guide layer 32 provides a flow channel for the water flow in the second flow channel 3112, thereby achieving the purpose of controlling the interruption and guidance of water flow.

[0026] The first guide gap 321 and the second guide gap 331 are offset along the circumference of the guide block 3. The fan-shaped orientation of the first water blocking block 21 and the second water blocking block 22 corresponds to the positions of the first guide gap 321 and the second guide gap 331, forming two independent water flow control states. By making the first guide gap 321 and the second guide gap 331 offset along the circumference of the guide block 3, and making the fan-shaped orientation of the first water blocking block 21 and the second water blocking block 22 correspond to the positions of the two gaps respectively, the purpose of forming two independent water flow control states is achieved, realizing independent regulation of water flow in different channels.

[0027] The faucet housing 1 is coaxially positioned with the water-blocking shaft 2 at its lower part, and a connecting pipe 4 is rotatably installed via a threaded connection. A sealing ring 41 is provided between the mating surface of the connecting pipe 4 and the faucet housing 1 to achieve a seal. By setting the connecting pipe 4 and the faucet housing 1 coaxially and threadedly connected at its lower part, and providing a sealing ring 41 on the mating surface, a stable connection and leak-proof purpose are achieved.

[0028] A diversion plate 15 is integrally formed directly below the equipment cavity 12. The diversion plate 15 is at the same angle as the vertical partition 311 in the initial flow guiding layer 31, with a suitable width and corresponding position in the vertical direction, together forming a preliminary diversion and guiding structure for the water flow. A drain hole 16 is provided at the lowest point of the water flow cavity 131 inside the outlet pipe 13. A water-blocking plug 5 is installed in the drain hole 16 by threaded rotation. The inner wall of the water flow cavity 131 has a slope structure, so that the water in the cavity can be collected along the slope to the drain hole 16. By forming a diversion plate 15 integrally below the equipment cavity 12 with the same angle as the vertical partition 311, a suitable width and corresponding position, a preliminary diversion and guiding structure for the water flow is formed. At the same time, a drain hole 16 with a water-blocking plug 5 is provided at the lowest point of the water flow cavity 131 in the outlet pipe 13. The slope of the inner wall guides the water to collect, achieving the purpose of efficient diversion and thorough drainage, realizing the dual effect of water flow guidance and prevention of water accumulation and freezing.

[0029] The end of the water-blocking shaft 2 extends outside the faucet housing 1. A rotary control handle 23 is fastened to the extended end of the water-blocking shaft 2. The rotary control handle 23 is used to drive the water-blocking shaft 2 to rotate axially. By fastening the rotary control handle 23 to the end of the water-blocking shaft 2 extending out of the faucet housing 1, the water-blocking shaft 2 can be driven to rotate axially, thereby achieving convenient control of the rotation of the water-blocking shaft 2 and realizing flexible adjustment of the water flow state.

[0030] Dual-channel independent control and water outlet switching state description: When the first water blocking block 21 is located directly above the first flow guide gap 321, the first water blocking block 21 completely blocks the water inlet of the first flow guide gap 321. At this time, the second water blocking block 22 is offset from the second flow guide gap 331 and does not form an obstruction. The water flow in the second channel 3112 flows into the second flow guide layer 33 through the second flow guide gap 331 in sequence, and is discharged to the first outlet 141 through the water flow avoidance groove 221 of the second water blocking block 22. When the second water blocking block 22 is located directly above the second flow guide gap 331, the second water blocking block 22 completely blocks the water inlet of the second flow guide gap 331. At this time, the positions of the first water blocking block 21, the first flow guide gap 321, and the second outlet 142 are all offset and do not form an obstruction. The water flow in the first channel 3111 flows into the first flow guide layer 32 through the first flow guide gap 321 in sequence, and is discharged to the second outlet 142.

[0031] The specific working principle is as follows: Two independent flow channels, a first flow channel 3111 and a second flow channel 3112, are set up as water inlet channels. These are combined with a guide block 3 inside the equipment cavity 12, featuring a first guide notch 321 and a second guide notch 331, as well as a first water-blocking block 21 and a second water-blocking block 22 adapted to the notch positions. A rotary control head 23 drives the water-blocking shaft 2 to rotate, allowing water to exit through the first outlet 141 and the second outlet 142 respectively without interference. This achieves the goal of switching to the other flow channel for normal water output when one flow channel is blocked, thus realizing single-channel... The device features independent operation and flexible switching of dual water flow paths, enhancing the reliability and continuous water supply capacity of the faucet under complex operating conditions. By adopting a slope structure design for the water flow cavity 131 of the outlet pipe 13 and opening a drain hole 16 at the lowest point of the water flow cavity 131 through which a water-blocking plug 5 is installed by thread, the water accumulated in the cavity is allowed to collect along the slope and be completely discharged through the drain hole 16. This effectively prevents residual water from freezing and clogging in low-temperature environments, ensuring the normal use of the faucet in cold weather and solving the problem of traditional faucets failing to dispense water due to water freezing.

[0032] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
