Description

Technical Field

[0001] This invention relates to the technical field of kitchen and bathroom faucets, and in particular to a pull-out faucet. Background Technology

[0002] Pull-out faucets are widely used because their showerheads can be pulled out to different positions to meet various water needs, offering convenience. A typical pull-out faucet's showerhead is connected to the water pipe via a pull-out hose, allowing it to be pulled out and mounted on the faucet body. A counterweight or counterweight assembly is usually installed and fixed to this pull-out hose, located below the countertop. Pull-out faucets typically use a handle to operate the valve core to control water flow. When a flush is needed, the pull-out hose is pulled out, opening the valve core to release water. When the user releases the pulled-out showerhead, it automatically returns to its original position due to gravity provided by the counterweight or counterweight assembly.

[0003] To make water flow more convenient, some faucets now feature pull-out control. These faucets utilize a reed switch to control the water flow when the shower head is pulled out, allowing water to flow directly without the need for a handle. A typical reed switch stops the sensor when water is released by pulling out the hose, and the switch controls the solenoid valve to open and release water. When the hose is pulled back to its original position, the reed switch closes the solenoid valve to stop water flow, and the sensor resumes operation. Examples include the intelligent control faucet disclosed in Chinese patent CN201420331760.6.

[0004] However, the aforementioned pull-out faucets require various sensors, solenoid valves, and other electronic components, resulting in higher manufacturing costs. Furthermore, they require electricity, consuming power and increasing operating costs for consumers. Summary of the Invention

[0084] The front and rear sides of the driving sleeve 51 can also be respectively provided with a front limiting part 513 and a rear limiting part 514, and the left side of the driving sleeve 51 below the driving part 511 is provided with a left limiting part 515, the front limiting part 513 and the rear limiting part 514 can be respectively and slidably clamped in the front limiting clamping groove 14 and the rear limiting clamping groove 15 formed by the abutment between the movable cavity cover plate 81 and the valve body seat 11 and the valve body side cover 12, and the left limiting part 515 slides in the sliding groove 16 provided on the right side of the valve body seat 11, so as to be matched with the driving limiting part 512 respectively, to realize the up and down limiting of the driving sleeve 51 in the driving sleeve movable cavity 8, and stably slide up and down.

[0085] The pull pipe 30 can move up and down through the driving sleeve 51, and the side wall of the pull pipe 30 is provided with a protruding limiting part 9. The outer side of the protruding limiting part 9 is a curved surface with a middle convex part and tapered upper and lower ends. The widest part of the protruding limiting part 9 is tightly fitted to the inner wall of the driving sleeve 51. After the shower head 20 is reset close to the faucet body 10, the protruding limiting part 9 of the pull pipe 30 is limited in the driving sleeve 51, and the driving sleeve 51 is compressed by the driving elastic member 83 to move away from the movable plug 4 in the first position under the action of friction. When the shower head 20 moves away from the faucet body 10, the protruding limiting part 9 of the pull pipe 30 moves away from the driving sleeve 51, and the driving sleeve 51 and the driving part 511 always remain close to the movable plug 4 in the second position under the action of the elastic force of the driving elastic member 83.

[0086] Meanwhile, when the shower head 20 moves away from the faucet body 10 and the pull pipe 30 moves up by a distance greater than the driving sleeve 51, the driving sleeve 51 cannot continue to move up due to the limitation of the driving sleeve movable cavity 8. Since the widest part of the protruding limiting part 9 is tightly fitted to the driving sleeve 51, and the pulling force on the pull pipe 30 and the protruding limiting part 9 is greater than the maximum static friction between the protruding limiting part 9 and the driving sleeve 51, the protruding limiting part 9 will continue to move up and separate from the driving sleeve 51. After the protruding limiting part 9 is limited, the driving sleeve 51 has a tendency to move down due to gravity, and the gravity can be overcome by the support of the driving elastic member 83, so that the driving part 511 of the driving sleeve 51 always remains in the second position, ensuring that the shower head 20 can continuously supply water.

[0087] In another embodiment, when the shower head 20 is further pulled out, in order to ensure that the driving sleeve 51 always remains in the second position, the driving sleeve movable cavity 8 can also be provided, and the driving sleeve 51 can also move up and down and be limited in the driving sleeve movable cavity 8. The upper end of the driving sleeve 51 is integrally provided with a driving sleeve extension part (not shown in the figure) that extends beyond the upper end of the driving sleeve movable cavity 8. The driving sleeve extension part can be sleeved on the outer periphery of the pull pipe 30 with the same inner diameter as the driving sleeve 51, and extends axially away from the shower head 20. In this way, the driving elastic member 83 can be removed. When the protruding limiting part 9 continues to move up and separate from the driving sleeve 51, the protruding limiting part 9 can also continue to move in the driving sleeve extension part, and can drive the driving sleeve 51 to overcome the gravity and always remain in the second position in the driving sleeve movable cavity 8, ensuring that the shower head 20 always supplies water. Moreover, this scheme has the advantage that the water can be turned off by returning the shower head 20. Specifically, when the shower head 20 pulls back the pull pipe 30, the protruding limiting part 9 of the pull pipe 30 can immediately drive the driving sleeve extension part and the driving sleeve 51 to move downward away from the movable plug 4, so as to realize the water turning off by returning, and can avoid the problem of water splashing during the resetting of the shower head 20.

[0088] In this embodiment, the drive mechanism 5 is mainly based on the protrusion provided on the drive sleeve 51, so that the drive sleeve 51 is always kept in the second position to ensure that the movable plug 4 always opens the water passage W. Of course, the drive sleeve 51 can also be removed and the protrusion can be directly set on the side wall of the pull tube 30. As long as the protrusion of the pull tube 30 is a long strip extending along the axial direction of the pull tube 30 away from the shower head 20 (this structure is not shown), the long strip protrusion can always be kept in the state of driving the inner end 41 of the movable plug 4 to open the water passage W when the shower head 20 is pulled out.

[0089] Example 2

[0090] like Figures 8 to 12 As shown, this embodiment is based on the same principle as the above embodiment 1, the main difference being the different structure of the non-electrically driven water outlet component 40.

[0091] See Figures 8 to 10 In this embodiment, the water passage W of the valve body 1 of the non-electrically driven water outlet assembly 40 is provided with a pilot valve 6; the main valve 61 of the pilot valve 6 has a left chamber 612 and a right chamber 613 separated by a diaphragm 611. The left chamber 612 has a chamber outlet 132 that movably connects the inlet end 2 and the outlet end 3. The right chamber 613 is connected to the pilot valve 62. A diaphragm elastic element 614 is provided in the right chamber 613 so that the diaphragm 611 is pressed by elastic force and movably blocks the chamber outlet 132. The diaphragm elastic element 614 is elastic. Taking a spring as an example; the diaphragm 611 has a connecting hole 6111 on the outer periphery of the chamber outlet 132 to connect the left chamber 612 and the right chamber 613; the movable plug 4 moves to open and close the pilot hole 621 of the pilot valve 62 to control the pilot valve 62 to move and connect the right chamber 613 of the main valve 61 and the water outlet 3, thereby controlling the diaphragm 611 to open the chamber outlet 132 and connect the water path W; the diameter of the chamber outlet 132 is larger than the diameter of the pilot hole 621, and the diameter of the pilot hole 621 is larger than the diameter of the connecting hole 6111.

[0092] By setting the pilot valve 6, in the initial state, the pilot hole 621 is elastically closed by the movable plug 4, and the water inlet 2 enters the left chamber 612. At the same time, the water enters the right chamber 613 from the left chamber 612, so that the water pressure in the left chamber 612 and the right chamber 613 are balanced, and the diaphragm 611, which is abutted by the diaphragm elastic element 614, stably blocks the chamber outlet 132 in the left chamber 612. When the shower head 20 is pulled out, causing the pull-out pipe 30 to move upward, the drive mechanism 5 of the pull-out pipe 30 drives the movable plug 4 to open the pilot hole 621, so that the pilot valve 62 connects the right chamber 613 and the outlet 3. That is, the water in the right chamber 613 flows out from the outlet 3. The diameter of the pilot hole 621 is larger than the diameter of the connecting hole 6111, so that the water pressure in the right chamber 613 drops and is less than the water pressure in the left chamber 612. The water in the left chamber 612 squeezes the diaphragm 611, causing it to compress the diaphragm elastic element 614, and at the same time opens the chamber outlet 132, thereby connecting the water passage W between the inlet 2 and the outlet 3.

[0093] After the shower head 20 is reset, the movable plug 4 is reset to reseal the pilot hole 621, the water pressure in the right cavity 613 rises to cooperate with the diaphragm elastic member 614, so that the diaphragm 611 reseals the chamber outlet 132 of the left cavity 612, and the water path W is closed.

[0094] Since the diameter of the pilot hole 621 is much smaller than the diameter of the chamber outlet 132, the opening and closing of the pilot hole 621 is used to control the conduction of the water path W, so that the driving part 511 of the pull pipe 30 only needs a small driving force to overcome the water pressure to conduct the water path W, ensuring the reliability of the product and making the operation more labor-saving.

[0095] In this embodiment, the main valve 61 and the pilot valve 62 of the pilot valve 6 are arranged side by side and coaxially on one side of the pull pipe 30 which moves up and down, and the pilot valve 62 is arranged close to the pull pipe 30; the pilot hole 621 of the pilot valve 62 is located between the pilot valve cavity 622 and the right cavity 613, and the pilot valve cavity 622 and the water outlet end 3 have a pilot valve hole 623; the movable plug 4 is movably arranged in the pilot valve cavity 622.

[0096] Referring to Figure 11 and Figure 12 , the valve body 1 of the non-power driven water outlet assembly 40 includes a valve body seat 11 and a valve body side cover 12 which are detachably connected and matched, the left cavity 612 and the right cavity 613 of the main valve 61 are formed between the valve body side cover 12 and the valve body seat 11, the outer periphery of the diaphragm 611 is fixed between the valve body side cover 12 and the valve body seat 11, the upper side of the left cavity 612 has a chamber inlet 131 connected to the water inlet end 2, and the middle part of the left cavity 612 has the chamber outlet 132 connected to the water outlet end 3; the valve body side cover 12 is close to the pull pipe 30, and is provided with the pilot valve cavity 622, the inside of the pilot valve cavity 622 is provided with the pilot hole 621 connected to the right cavity 613, and the outside of the pilot valve cavity 622 is provided with the movable plug opening 121 facing the pull pipe 30;

[0097] The movable plug 4 movably passes through the pilot valve cavity 622; the inner end 41 of the movable plug 4 passes through the pilot hole 621 from the pilot valve 62 and has a radially outwardly protruding inner limiting part 411, a sealing plug 412 for sealing the pilot hole 621 is arranged between the inner limiting part 411 of the movable plug 4 and the pilot hole 621; the outer end 42 of the movable plug 4 has a radially outwardly protruding outer limiting part 421, and the outer limiting part 421 movably extends out of or retreats into the movable plug opening 121, the outer limiting part 421 is peripherally sleeved with a sealing ring 7 which seals the movable plug opening 121 when the outer end 42 of the movable plug 4 moves; the movable plug elastic member 43 is arranged between the outer limiting part 421 of the movable plug 4 and the inner wall of the movable plug opening 121, the movable plug 4 is abutted by the movable plug elastic member 43 to make the outer end 42 extend out of the movable plug opening 121 and make the inner end 41 seal the pilot hole 621;

[0098] Meanwhile, the communicating hole 6111 of the diaphragm 611 is provided with a plug rod 615 extending from the right cavity 613 to the left cavity 612. Since the diaphragm 611 can move relative to the plug rod 615, the plug rod 615 mainly has the effect of removing dirt, avoiding the blockage of the communicating hole 6111.

[0108] The valve body side cover 12 and the pilot valve cover plate 624 are also respectively provided with a sealing ring 7 for sealing when matched with the valve body seat 11.

[0109] The outer end 42 of the movable plug 4 of the present embodiment is lowered, and the driving part 511 of the corresponding driving sleeve 51 is also adaptively lowered.

[0110] Embodiment 4

[0111] As Figures 17 to 21 , the structure of the present embodiment is the same as the basic principle and basic structure of the above-mentioned embodiment 3, and the main difference is that the non-electrically driven water outlet assembly 40, the movable plug 4 and the driving part 511 are different in structure.

[0112] The movable plug 4 of the present embodiment is also reciprocally movably arranged in the valve body 1, and the movable plug 4 and the valve body 1 are provided with a movable plug elastic member 43. The movable plug elastic member 43 abuts to control the movable plug 4 to close the water passage W. The driving mechanism 5 includes a driving part 511, and the driving part 511 and the movable plug 4 are respectively made of materials that are magnetically attracted to each other. The driving part 511 is close to the movable plug 4 to magnetically attract the movable plug 4 to move to open the water passage W. The movable plug 4 of the present embodiment is made of a magnetic material, and the driving part 511 is a magnet which is protrudingly arranged on the outer wall of the driving sleeve 51.
