Description

Technical Field

[0001] The utility model discloses a cold start type faucet and belongs to the technical field of faucets. Background Art

[0002] Faucet is a popular name for water valve, which is used to control the size of water flow and has the effect of saving water. The replacement speed of faucets is very fast, from the old cast iron process to the electroplated knob type, and then to the stainless steel single-temperature single-control faucet, stainless steel dual-temperature dual-control faucet, and kitchen semi-automatic faucet; now, more and more consumers will consider the material, function, shape and other aspects when purchasing faucets.

[0003] At present, the hot water pipe of the hot and cold water mixing faucet is generally connected to an electric water heater or a gas water heater. When users use cold water, they usually turn the faucet handle to the middle position and then turn it on. However, the handle of the hot and cold water faucet is generally in a mixed state of hot and cold water when it is in the middle position, and the gas water heater will immediately start to heat the internal water source again when the internal hot water flows out, causing the hot water in the gas water heater to flow out when the user does not need to use hot water, causing the gas water heater to start frequently for heating, resulting in energy waste, which is not conducive to energy conservation and emission reduction, and environmental protection.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] The utility model aims to solve the above-mentioned problem and provide a cold start faucet, which has the effect of enabling the faucet to be opened from the maximum opening angle of the cold water end each time it is opened, thereby saving energy.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme, including a faucet body, a handle and a valve core, the upper end of the faucet body is provided with a water valve joint for connecting the valve core, the valve core includes a valve body and a valve handle, the valve body is connected to the faucet body through the water valve joint, the valve handle is rotatably arranged at the upper end of the valve body, the handle is arranged at the upper end of the faucet body and is connected to the valve handle, the lower end and the front end of the faucet body are respectively provided with a water inlet and a water outlet, the water inlet is provided with a cold water pipe and a hot water pipe connected to the valve core, the water outlet is provided with a water outlet pipe connected to the valve core, the valve handle is a rectangular structure, the angle at which the valve handle opens the valve core is the maximum opening angle of the cold water end when the valve handle is in the middle, and the maximum opening angle of the hot water end is achieved when the valve handle is rotated ninety degrees to the left from the middle, and a limiting block is provided on the inner side of the upper end of the faucet body, the limiting block is arranged on the left side of the valve handle and the end close to the valve handle is arc-shaped.

[0007] By adopting the above technical scheme, hot water and cold water flow into the valve core from the water inlet through the hot water pipe and the cold water pipe, mix in the valve core and then flow out from the water outlet through the water outlet pipe. The mixing ratio of hot and cold water can be controlled by turning the handle to control the rotation angle of the valve handle. At the same time, the opening and closing of the valve core can be conveniently controlled. When the valve handle is in the middle, the rotation angle of the handle connected to the valve handle is also in the middle position, which conforms to the user's usage habits and visual habits. At this time, the opening angle in the valve core is at the maximum opening angle of the cold water end and the hot water end is in a closed state. At this time, the water source flowing out is pure cold water, and the user can turn the handle to the left to adjust the hot and cold water state according to needs, while ensuring the normal operation of the hot and cold water faucets. While maintaining the effective use effect, it avoids frequent start-up of the gas water heater, reduces energy usage, and achieves the effect of energy conservation and emission reduction. Through the setting of the limiting block, it cooperates with the rectangular structure of the valve handle, so that the valve handle cannot be rotated to the left when the valve core is closed. When hot water is to be used, the valve handle is first opened to open the valve core, and the valve handle can be rotated normally after tilting. At the same time, when the valve handle is turned to the left and opened at the hot water end, it cannot be closed normally due to the restriction of the limiting block, thereby effectively reminding the user to turn the handle to the middle position, so that it can still be opened from the cold water end when used next time, thereby ensuring its energy-saving effect. The arc-shaped structure at the right end of the limiting block can guide the valve handle, making its closing and resetting smoother and more convenient.

[0008] Preferably, the left end of the limiting block passes through the faucet body and extends to the side of the faucet body, the limiting block is slidably connected to the faucet body, and the faucet body is provided with a fixing device for fixing the limiting block.

[0009] By adopting the above technical solution, the left end of the limiting block extends out of the faucet body and is slidably connected to the faucet body, so that the limiting block can move outward to release the restriction on the rotation of the valve handle, so that the valve handle can be closed at the hot water end, so that the user does not need to turn the handle every time when he needs to use hot water frequently in a short time, thereby improving the convenience of using the faucet. At the same time, the position of the limiting block can be fixed by setting the fixing device, thereby improving the stability of the use of the limiting block.

[0010] Preferably, the fixing device includes a fixing rod and a return spring, the faucet body and the limiting block are respectively provided with a first fixing groove and a second fixing groove, the return spring is arranged in the first fixing groove, the fixing rod is movably arranged in the first fixing groove and one end is connected to the return spring and the other end extends into the second fixing groove, the fixing rod is provided with a lever, a sliding groove is provided on the outside of the faucet body, and the lever passes through the sliding groove and extends to the outside of the faucet body.

[0011] By adopting the above technical solution, the fixing rod remains in the state of extending into the second fixing groove in the limiting block under the action of the return spring, so that a force can be stably applied to the limiting block to fix it. When the limiting block needs to be moved, the sliding lever drives the fixing rod to move so that it withdraws from the second fixing groove to release the fixation of the limiting block. When the lever is released, the fixing rod can be reset under the action of the return spring to restore the fixation of the limiting block.

[0012] Preferably, a protrusion is provided at one end of the limiting block extending to the outside of the faucet body.

[0013] By adopting the above technical solution and setting the protrusion, the limiting block has a better force point, which makes it easier for the user to control the movement of the limiting block.

[0014] Preferably, a limiting block is provided at the right end of the limiting block.

[0015] By adopting the above technical solution and setting the limit block, it is possible to effectively prevent the limit block from slipping out of the faucet body, avoid the limit block from being lost after being taken out, and improve the stability of the device.

[0016] Preferably, the faucet body is provided with a filter head connected to the water outlet pipe at the water outlet.

[0017] By adopting the above technical solution and setting a filter head, impurities in the water can be effectively filtered out, the water quality can be improved, and users can be provided with a healthier and safer water use experience.

[0018] Preferably, the cold water pipe, hot water pipe and water outlet pipe are all made of braided hoses.

[0019] By adopting the above technical solutions, the braided hose material has the characteristics of being soft, durable, and not easy to break, which helps to improve the overall performance and service life of the faucet.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] First, the installation angle of the valve core makes the valve handle in the middle position at the maximum opening angle at the cold water end, so that when the user's handle is in the middle position under normal use habits, no hot water will flow into the valve core, effectively avoiding the frequent use of the faucet without hot water, hot water flowing into the valve core and mixing with cold water, causing the gas water heater to frequently start heating water, thereby effectively saving energy;

[0022] Secondly, by setting the limiting block, the valve handle can be restricted so that the valve handle cannot be closed when hot water is released after turning left, reminding the user to reset the valve handle, so that the faucet can still be opened from the cold water end when it is opened next time, ensuring its energy-saving effect;

[0023] Thirdly, the arc-shaped structure at the right end of the limiting block can guide the valve handle while limiting it, making the valve handle reset more smoothly and improving the convenience of using the device;

The valve body 301 is connected to the faucet body 1 through the water valve connector 4. The valve handle 302 is rotatably arranged on the upper end of the valve body 301. The handle 2 is arranged on the upper end of the faucet body 1 and connected to the valve handle 302. The lower end and the front end of the faucet body 1 are respectively provided with a water inlet 5 and a water outlet 6. The water inlet 5 is provided with a cold water pipe 7 and a hot water pipe connected to the valve core 3. The water outlet 6 is provided with a water outlet pipe 8 connected to the valve core 3. Hot water and cold water are connected through The hot water pipe and the cold water pipe 7 flow into the valve core 3 from the water inlet 5, mix in the valve core 3 and then flow out from the water outlet 6 through the water outlet pipe 8. The mixing ratio of the hot and cold water can be controlled by turning the handle 2 to control the rotation angle of the valve handle 302. At the same time, the opening and closing of the valve core 3 can be conveniently controlled. The valve handle 302 is a rectangular parallelepiped structure. The angle at which the valve handle 302 opens the valve core 3 is the maximum opening angle of the cold water end when the valve handle 302 is in the middle. The maximum opening angle of the hot water end is when the valve handle 302 is rotated ninety degrees to the left from the middle. When the valve handle 302 is in the middle, the rotation angle of the handle 2 connected to the valve handle 302 is also in the middle position. The valve body 1 is provided with a limiting block 9 on the inner side of the upper end thereof, and the limiting block 9 is provided on the left side of the valve handle 302 and the end close to the valve handle 302 is in an arc shape. , cooperates with the rectangular structure of the valve handle 302, so that the valve handle 302 cannot be rotated to the left when it is in the state of closing the valve core 3. When hot water is to be used, the valve handle 302 is first opened to open the valve core 3, and the valve handle 302 can be rotated normally by tilting. At the same time, when the valve handle 302 is rotated to the left and is opened at the hot water end, it is restricted by the limiting block 9 and cannot be closed normally, thereby effectively reminding the user to turn the handle 2 to the middle position, so that it can still be opened from the cold water end when used next time, thereby ensuring its energy-saving effect. The arc-shaped structure at the right end of the limiting block 9 can guide the valve handle 302, making its closing and resetting smoother and more convenient.

[0032] The left end of the limiting block 9 passes through the faucet body 1 and extends to the side of the faucet body 1. The limiting block 9 is slidably connected to the faucet body 1. The faucet body 1 is provided with a fixing device for fixing the limiting block 9. The left end of the limiting block 9 extends out of the faucet body 1 and is slidably connected to the faucet body 1, so that the limiting block 9 can be moved outward to release the restriction on the rotation of the valve handle 302, so that the valve handle 302 can be closed at the hot water end, so that the user does not need to turn the handle 2 every time when the user needs to use hot water frequently for a short time, thereby improving the convenience of using the faucet. At the same time, the position of the limiting block 9 can be fixed by setting the fixing device, thereby improving the stability of the use of the limiting block 9.

The braided hose material has the characteristics of being soft, durable, and not easy to break, which helps to improve the overall performance and service life of the faucet.

[0034] When the user needs to use the faucet, the handle 2 is lifted upwards to tilt the valve handle 302 to open the valve core 3 so that water can flow out. When the valve handle 302 is closed, it is blocked by the limiting block 9 and cannot be turned left, so that the valve handle 302 is kept open at the maximum opening angle of the cold water end in the middle, thereby avoiding hot water outflow and causing the gas water heater to start frequently, effectively saving resources. After the valve handle 302 is opened, it is in a tilted state and can be normally turned left to release hot water. After the valve handle 302 is turned left, due to the effect of the limiting block 9, the valve handle 302 cannot be closed after turning left, thereby reminding the user The user resets the valve handle 302 to the cold water end and then closes it, so that it is still open at the cold water end when it is used next time. At the same time, the arc-shaped structure at the right end of the limiting block 9 can effectively guide the valve handle 302 to make its reset smoother. When hot water is needed frequently, the sliding lever 13 controls the fixing rod 10 to withdraw from the second fixing groove in the limiting block 9, so that the fixing rod 10 releases the fixation of the limiting block 9 and the limiting block 9 can be pulled out through the protrusion 15, thereby releasing the restriction of the limiting block 9 on the rotation angle of the valve handle 302, so that it can be closed at the hot water end, saving energy while improving the convenience of using the faucet.
