Description

A pull-out faucet Technical Field

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

[0002] Pull-out faucets are widely used because their showerhead can be pulled out to different positions to meet varying water needs, making them convenient to use. The showerhead of a typical pull-out faucet is connected to the water outlet pipe via a pull-out hose, allowing it to be pulled out from the faucet body. A weight or weight assembly is typically mounted and fixed to the pull-out hose and located below the countertop. Pull-out faucets typically use a handle to operate a valve core to control the water flow. To flush, pull out the pull-out hose and open the valve core to release water. When the user releases the pulled showerhead, the weight or weight assembly automatically resets the showerhead.

[0003] To provide more convenient water flow, some faucets with pull-out control now use a reed switch to control the water flow. This allows water to flow directly when the showerhead is pulled out, eliminating the need for a handle to control the water flow. A common reed switch typically stops the sensor probe when the pull-out hose is pulled out to release water, and the reed switch controls the solenoid valve to open and release water. When the pull-out hose is reset, the reed switch controls the solenoid valve to close, stopping water flow and resuming operation of the sensor probe. For example, this intelligent control faucet disclosed in Chinese patent CN201420331760.6.

[0004] However, the aforementioned pull-out faucets require various electronic components such as sensors and solenoid valves, resulting in high manufacturing costs.

Modes for Carrying Out the Invention

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0056] Example 1

[0057] As shown in FIG1 to FIG7 , a pull-out faucet 100 of the present invention includes a faucet body 10 , a shower head 20 , a pull-out tube 30 and a non-electrically driven water outlet assembly 40 .

[0058] The shower head 20 is detachably mounted on one end of the faucet body 10 , and the pull-out tube 30 is reciprocally movably disposed inside the faucet body 10 .

[0059] One end of the pull-out tube 30 is connected to the shower head 20, and the other end is connected to the water outlet end 3 of the non-electrically driven water outlet component 40; the non-electrically driven water outlet component 40 is arranged in the faucet body 10 and is located on one side between the two ends of the pull-out tube 30; the non-electrically driven water outlet component 40 includes a valve body 1, a water inlet end 2 for water intake provided on the valve body 1, the water outlet end 3 provided on the valve body 1, and a movable plug 4 for movably opening and closing the water channel W between the water inlet end 2 and the water outlet end 3.

[0060] A driving mechanism 5 is provided on the side wall of the pull-out tube 30 ; when the shower head 20 leaves the faucet body 10 , it drives the pull-out tube 30 and the driving mechanism 5 to move toward the movable plug 4 ; after the driving mechanism 5 approaches the movable plug 4 , it drives the movable plug 4 to move, thereby opening the waterway W; after the shower head 20 returns to the faucet body 10 , it controls the driving mechanism 5 to move away from the movable plug 4 ; after the driving mechanism 5 moves away from the movable plug 4 , the movable plug 4 returns to its original position, thereby closing the waterway W.

[0061] The non-electrically driven water outlet assembly 40 of the present invention refers to a mechanical water outlet valve structure that does not require electrical drive such as a solenoid valve or an electric control valve.

[0062] In this way, when the user pulls the shower head 20 away from the faucet body 10, the waterway W is directly opened, and water flows directly from the shower head 20, without the need for a handle to operate it. The portion of the pull-out tube 30 that passes through the lower portion of the faucet body 10 can be connected to the water outlet 3 and can be equipped with a weight assembly (not shown). When the user releases their hand, the shower head 20 automatically resets under the weight of the weight assembly, or can be manually returned to the faucet body 10. After the reset is complete, the waterway W is closed, and the shower head 20 automatically shuts off the water.

[0063] The pull-out faucet 100 of the present invention is easy to use, has a non-electrically driven structure, is highly versatile, does not require electricity, and has low cost of use.

[0064] In this embodiment, the water inlet 2 and the water outlet 3 are both located below the valve body 1 of the non-electrically driven water outlet component 40, and the water inlet 2 may include a cold water inlet 21 and a hot water inlet 22, which are located on the front and back sides of the water outlet 3; the cold water inlet 21 and the hot water inlet 22 are both connected to the chamber inlet 131 described below, and the cold water inlet 21 and the hot water inlet 22 can be connected to cold and hot water inlet pipes respectively (not shown in the figure).

[0065] As shown in Figure 2, the non-electrically driven water outlet component 40 takes a mechanical water outlet valve structure as an example and can be set at the valve seat position of the faucet body 10, and the non-electrically driven water outlet component 40 and the handle water outlet valve 50 in the valve seat are arranged side by side to make full use of the internal space of the faucet body 10 and control the size of the product; the handle water outlet valve 50 can be an existing common handle-controlled mixing valve structure, and the cold water outlet 21 and the hot water outlet 22 are connected to the chamber inlet 131 after being matched with the handle water outlet valve 50, that is, connected to the water path W, so as to provide mixed water of cold and hot water.

[0066] Of course, the water inlet end 2 may also be just a single water inlet, that is, it does not cooperate with the handle water outlet valve 50, but is a separate water supply channel W.

[0067] 3 to 5 , in this embodiment, the movable plug 4 is reciprocatingly mounted in the valve body 1 , and a movable plug elastic member 43 is provided between the movable plug 4 and the valve body 1 . The movable plug elastic member 43 is, for example, a spring, which provides elastic force for returning the movable plug 4 to its original position; the movable plug elastic member 43 presses against the inner end of the movable plug 4 to control the closure of the waterway W; the outer end of the movable plug 4 movably extends out of the valve body 1 and toward the withdrawal tube 30; the driving mechanism 5 includes a driving portion 511 radially protruding from the outer peripheral side of the withdrawal tube 30; and when the driving mechanism 5 approaches the movable plug 4, the driving portion 511 presses against the movable plug 4 to move and open the waterway W.

[0068] 6 and 7 , the valve body 1 of the non-electrically driven water outlet assembly 40 includes a valve body seat 11 and a valve body side cover 12 that are detachably connected to each other on the left and right sides. The water inlet end 2 and the water outlet end 3 are both located below the valve body seat 11 .

[0069] A valve body chamber 13 is formed between the valve body side cover 12 and the valve body seat 11. The upper side of the valve body chamber 13 has a chamber inlet 131 connected to the water inlet end 2, and one side of the chamber inlet 131 of the valve body chamber 13 has a chamber outlet 132 connected to the water outlet end 3; the valve body side cover 12 is close to the pull-out tube 30, and is provided with a movable plug opening 121 facing the pull-out tube 30, and the inner wall of the movable plug opening 121 is provided with a side cover through hole 1211 and is connected to the valve body chamber 13.

[0070] The inner end 41 of the movable plug 4 is used to movably open and close the chamber outlet 132 . The outer end 42 of the movable plug 4 close to the drawing tube 30 is driven by the driving portion 511 to drive the inner end 41 to move.

[0071] Specifically, in this embodiment, the inner end 41 of the movable plug 4 passes through the chamber outlet 132 from the valve body chamber 13 and has a radially outwardly protruding inner limit portion 411, and a sealing plug 412 for sealing the chamber outlet 132 is provided between the inner limit portion 411 of the movable plug 4 and the chamber outlet 132; the outer end 42 of the movable plug 4 has a radially outwardly protruding outer limit portion 421, and the outer limit portion 421 is movably extended out of the movable plug opening 121 or retracted into the movable plug opening 121, and a sealing ring 7 is sleeved on the outer periphery of the outer limit portion 421 for sealing the movable plug opening 121 when the outer end 42 of the movable plug 4 moves; a movable plug elastic member 43 is provided between the inner side surface of the outer limit portion 421 of the movable plug 4 and the inner wall of the movable plug opening 121, and the movable plug 4 is pushed by the movable plug elastic member 43 so that the outer end 42 of the movable plug extends out of the movable plug opening 121, so that the inner end 41 closes the chamber outlet 132.

[0072] Thus, when the shower head 20 drives the pull-out tube 30 to move, the pull-out tube 30 drives the driving mechanism 5 and the outwardly protruding driving portion 511 upwardly to approach the outer end 42 of the movable plug 4. The outwardly protruding driving portion 511 abuts against the outer end 42 of the movable plug 4, causing the movable plug 4 to overcome the elastic force of the movable plug elastic member 43 and move within the valve body chamber 13. This in turn controls the inner limiting portion 411 and the sealing plug 412 of the inner end 41 of the movable plug 4 to move away from the chamber outlet 132, thereby connecting the water path W between the water inlet 2 and the water outlet 3 and allowing water to flow from the shower head 20. When the shower head 20 is released and the pull-out tube 30 is reset, the driving portion 511 moves away from the outer end 42 of the movable plug 4. The movable plug 4, under the elastic force of the movable plug elastic member 43, drives the inner end 41 of the movable plug 4 to return to its original position, thereby closing the water path W.

[0073] As shown in Figures 3 to 7, in this embodiment, the driving mechanism 5 includes a driving sleeve 51 that is sleeved on the outer periphery of the side wall of the pulling tube 30, and the driving sleeve 51 can move up and down at the first position and the second position on one side of the non-electrically driven water outlet component 40; the left side of the upper end of the driving sleeve 51 has the driving part 511 that drives the movable plug 4 to move, and the driving part 511 is a protrusion that radially protrudes from the outer wall of the driving sleeve 51, and the protrusion fits the side of the valve body 1 and moves; when the driving sleeve 51 is in the second position, the protrusion drives the movable plug 4 to move.

[0074] After the shower head 20 is reset and moved closer to the faucet body 10, the pull-out tube 30 drives the driving portion 511 of the driving sleeve 51 away from the movable plug 4 and is located in the first position, and the movable plug 4 is reset to close the waterway W; when the shower head 20 is away from the faucet body 10, the pull-out tube 30 drives the driving portion 511 of the driving sleeve 51 close to the movable plug 4 and is located in the second position, and the protrusion drives the movable plug 4 to move and open the waterway W.

[0075] When the shower head 20 and the pull-out tube 30 are pulled out a fixed distance, the driving sleeve 51 is always in the second position, and the shower head 20 always discharges water. When the shower head 20 is further pulled out, in order to ensure that the driving sleeve 51 is always in the second position, a driving sleeve movable cavity 8 can be provided on one side of the non-electrically driven water outlet component 40 so that the driving sleeve 51 can be limited in the driving sleeve movable cavity 8 when it can move up and down.

[0076] The driving sleeve active cavity 8 is formed by an active cavity cover plate 81 which is arranged on the right side of the valve body seat 11 and the valve body side cover 12. A movable groove 82 is provided on the right side of the driving sleeve active cavity 8, and a driving elastic member 83 is provided in the movable groove 82. The driving sleeve 51 is limited in the driving sleeve active cavity 8, and a driving limiting portion 512 is protruding from the side wall of the driving sleeve 51 toward the movable groove 82. The driving limiting portion 512 is connected and matched with one end of the driving elastic member 83. The driving elastic member 83 of this embodiment is a spring. The driving limiting portion 512 is passed through the upper end of the spring, and the lower end of the spring presses against the bottom of the movable groove 82. Therefore, the driving sleeve 51 and the driving portion 511 have a tendency to move upward and approach the movable plug 4 under the elastic force of the driving elastic member 83.

[0077] The front and rear sides of the driving sleeve 51 can also be respectively provided with a front limiting portion 513 and a rear limiting portion 514, and the left side of the driving sleeve 51 is provided with a left limiting portion 515 below the driving portion 511. The front limiting portion 513 and the rear limiting portion 514 can be respectively slidably clamped in the front limiting slot 14 and the rear limiting slot 15 formed by the docking between the active cavity cover plate 81 and the valve body seat 11 and the valve body side cover 12, and the left limiting portion 515 slides in the sliding slot 16 set on the right side of the valve body seat 11 to cooperate with the driving limiting portion 512 respectively, so as to realize the upper and lower limiting of the driving sleeve 51 in the driving sleeve active cavity 8, and stably slide up and down.

[0078] The pull-out tube 30 can move up and down through the drive sleeve 51. A raised stopper 9 is provided on the sidewall of the pull-out tube 30. The outer surface of the raised stopper 9 is a curved surface that is convex in the middle and tapers at both ends. The widest part of the raised stopper 9 fits tightly against the inner wall of the drive sleeve 51. After the shower head 20 is reset and positioned close to the faucet body 10, the raised stopper 9 of the pull-out tube 30 is retained within the drive sleeve 51. The frictional force causes the drive sleeve 51 to compress the drive elastic member 83 and move away from the movable plug 4 to the first position. When the shower head 20 is moved away from the faucet body 10, the raised stopper 9 of the pull-out tube 30 moves away from the drive sleeve 51. The elastic force of the drive elastic member 83 causes the drive sleeve 51 and the drive portion 511 to remain in the second position close to the movable plug 4.

[0079] At the same time, when the shower head 20 leaves the faucet body 10 and drives the pull-out tube 30 to move upward by a distance greater than the distance the drive sleeve 51 moves upward, the drive sleeve 51 is limited by the drive sleeve active cavity 8 and cannot continue to move upward. Since the widest part of the raised limiting portion 9 is tightly fitted with the drive sleeve 51, and the pulling force applied to the pull-out tube 30 and the raised limiting portion 9 is greater than the maximum static friction between the raised limiting portion 9 and the drive sleeve 51, the raised limiting portion 9 will continue to move upward and separate from the drive sleeve 51 as the pull-out tube 30 moves away from the drive sleeve 51. Without the limitation of the raised limiting portion 9, the drive sleeve 51 has a tendency to descend due to gravity, and this gravity can be overcome by the support of the driving elastic member 83, so that the driving portion 511 of the drive sleeve 51 is always maintained in the second position, ensuring sustainable water discharge from the shower head 20.

[0080] In another embodiment, to ensure that the drive sleeve 51 remains in the second position when the shower head 20 is further withdrawn, a similar drive sleeve active cavity 8 can be provided. Similarly, the drive sleeve 51 can be constrained within the active cavity 8 to allow for vertical movement. The upper end of the drive sleeve 51 can be integrally provided with a drive sleeve extension (not shown) extending beyond the upper end of the active cavity 8. The drive sleeve extension can have the same inner diameter as the drive sleeve 51 and be positioned around the outer periphery of the withdrawal tube 30, extending axially along the withdrawal tube 30 away from the shower head 20. This eliminates the need for the drive spring 83. As the raised stop 9 continues to move upward and away from the drive sleeve 51 as the withdrawal tube 30 moves further upward, the raised stop 9 can continue to move within the drive sleeve extension, forcing the drive sleeve 51 to overcome gravity and remain constrained in the second position of the active cavity 8, ensuring constant water flow from the shower head 20. This solution also offers the advantage of being able to shut off the water supply by simply retracting the shower head 20. Specifically, when the shower head 20 drives the pull-out tube 30 to retract, the raised limit portion 9 of the pull-out tube 30 can immediately drive the extension portion of the drive sleeve and the drive sleeve 51 to move downward and away from the movable plug 4, so as to achieve the retraction and water shut-off, thereby avoiding the problem of water spilling during the resetting process of the shower head 20.

[0081] The driving mechanism 5 of this embodiment primarily utilizes a protrusion provided on the driving sleeve 51 as an example. This maintains the driving sleeve 51 in the second position, thereby ensuring that the movable plug 4 always opens the waterway W. Of course, the driving sleeve 51 can also be removed, and the protrusion provided directly on the sidewall of the pull-out tube 30 . As long as the protrusion on the pull-out tube 30 is in the form of an elongated strip extending axially along the pull-out tube 30 (this structure is not shown), the elongated protrusion will always remain in the position of driving the inner end 41 of the movable plug 4 to open the waterway W when the shower head 20 is pulled out.

[0082] Example 2

[0083] As shown in FIG8 to FIG12 , the basic principle of this embodiment is the same as that of the above-mentioned embodiment 1, and the main difference lies in the structure of the non-electrically driven water outlet component 40 .

[0084] Referring to Figures 8 to 10, a pilot valve 6 is provided in the water path W of the valve body 1 of the non-electrically driven water outlet assembly 40 of this embodiment; 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 water inlet end 2 and the water outlet end 3. The right chamber 613 is connected to the pilot valve 62. A diaphragm elastic member 614 is provided in the right chamber 613 so that the diaphragm 611 is elastically pressed to movably block the chamber outlet 132. The diaphragm elastic member 614 is provided in the right chamber 613. 14 Taking the spring as an example; the diaphragm 611 is provided with a connecting hole 6111 on the periphery of the chamber outlet 132 to connect the left chamber 612 and the right chamber 613; the movable plug 4 movably opens and closes the pilot hole 621 of the pilot valve 62 to control the pilot valve 62 to movably 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.

[0085] By setting the pilot valve 6, in the initial state, the pilot hole 621 is elastically closed by the movable plug 4, and water from the water inlet end 2 enters the left chamber 612, and at the same time 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 kept balanced, so that the diaphragm 611, which is supported by the diaphragm elastic member 614, stably blocks the chamber outlet 132 in the left chamber 612. When the shower head 20 is pulled out, causing the pull-out tube 30 to move upward, the driving mechanism 5 of the pull-out tube 30 drives the movable plug 4 to open the pilot hole 621, causing the pilot valve 62 to connect the right chamber 613 and the water outlet 3. That is, water in the right chamber 613 flows out of the water outlet 3. The diameter of the pilot hole 621 is larger than that of the connecting hole 6111, causing the water pressure in the right chamber 613 to drop to 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 member 614, and at the same time opens the chamber outlet 132, thereby connecting the water path W between the water inlet 2 and the water outlet 3.

[0086] After the shower head 20 is reset, the movable plug 4 is reset to re-block the pilot hole 621 . The water pressure in the right chamber 613 rises, cooperating with the diaphragm elastic member 614 , so that the diaphragm 611 re-blocks the chamber outlet 132 of the main left chamber 612 , closing the water path W.

[0087] 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 pulling tube 30 only needs a smaller driving force to overcome the water pressure and conduct the water path W, thereby ensuring the reliability of the product and making operation more labor-saving.

[0088] 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-out tube 30 that moves up and down, and the pilot valve 62 is arranged close to the pull-out tube 30; the pilot hole 621 of the pilot valve 62 is located between the pilot valve cavity 622 and the right cavity 613, and there is a pilot valve hole 623 between the pilot valve cavity 622 and the water outlet end 3; the movable plug 4 can be reciprocated left and right in the pilot valve cavity 622.

[0089] 11 and 12 , the valve body 1 of the non-electrically driven water outlet assembly 40 includes a valve body seat 11 and a valve body side cover 12 that are detachably connected to each other on the left and right sides. The left chamber 612 and the right chamber 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 chamber 612 has a chamber inlet 131 connected to the water inlet end 2, and the middle part of the left chamber 612 has the chamber outlet 132 connected to the water outlet end 3; the valve body side cover 12 is close to the pull-out tube 30 and is provided with a pilot valve chamber 622. The inner side of the pilot valve chamber 622 is provided with the pilot hole 621 connected to the right chamber 613, and the outer side of the pilot valve chamber 622 is provided with a movable plug opening 121 facing the pull-out tube 30.

[0090] The movable plug 4 can reciprocate 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 limit portion 411, and a sealing plug 412 for sealing the pilot hole 621 is provided between the inner limit portion 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 limit portion 421, and the outer limit portion 421 can be movably extended out of the movable plug opening 121 or retracted into the movable plug opening 121, and a sealing ring 7 is sleeved on the outer periphery of the outer limit portion 421 for sealing the movable plug opening 121 when the outer end 42 of the movable plug 4 moves; a movable plug elastic member 43 is provided between the outer limit portion 421 of the movable plug 4 and the inner wall of the movable plug opening 121, and the movable plug 4 is pushed by the movable plug elastic member 43 so that the outer end 42 of the movable plug 4 extends out of the movable plug opening 121 and the inner end 41 closes the pilot hole 621.

[0091] Meanwhile, a rod 615 extending from the right cavity 613 to the left cavity 612 is provided in the communication hole 6111 of the diaphragm 611. Since the diaphragm 611 can move relative to the rod 615, the rod 615 mainly has a cleaning effect to prevent the communication hole 6111 from being blocked.

[0092] Example 3

[0093] The structure of this embodiment is the same as that of the above-mentioned embodiment 2 in terms of basic principle and basic structure, the main difference being that the structure of the pilot valve 6 in the non-electrically driven water outlet assembly 40 is different.

[0094] As shown in Figures 13 to 16, the main valve 61 and the pilot valve 62 of the pilot valve 6 of this embodiment are arranged in parallel on one side of the pull-out tube 30 that moves up and down; the lateral volume of the non-electrically driven water outlet component 40 can be reduced, so as to fully utilize the space inside the faucet body 10.

[0095] The pilot hole 621 of the pilot valve 62 is located between the pilot valve cavity 622 and the water outlet 3, and a pilot valve hole 623 is provided between the pilot valve cavity 622 and the right cavity 613 of the main valve 61; the movable plug 4 is arranged in the pilot valve cavity 622 so as to be able to reciprocate left and right.

[0096] 15 and 16 , the valve body 1 of the non-electrically driven water outlet assembly 40 includes a valve body seat 11 , a valve body side cover 12 and a pilot valve cover plate 624 . The valve body side cover 12 and the pilot valve cover plate 624 are detachably connected to the valve body seat 11 on the left and right sides, respectively.

[0097] The left chamber 612 and the right chamber 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 chamber 612 has a chamber inlet 131 connected to the water inlet end 2, and the middle part of the left chamber 612 has the chamber outlet 132 connected to the water outlet end 3.

[0098] The pilot valve cover plate 624 is located below the valve body side cover 12 and close to the pull-out tube 30. The pilot valve cavity 622 is formed between the pilot valve cover plate 624 and the valve body seat 11. The pilot hole 621 is provided on the inside of the pilot valve cavity 622 to connect to the water outlet end 3. The outer side of the pilot valve cavity 622 is provided with a movable plug opening 121 facing the pull-out tube 30.

[0099] 13 and 14 , the movable plug 4 is reciprocatingly arranged 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 limit portion 411 , and a sealing plug 412 for sealing the pilot hole 621 is provided between the inner limit portion 411 of the movable plug 4 and the pilot hole 621 ; the outer end 42 of the movable plug 4 can be movably extended out of the movable plug opening 121 or retracted into the movable plug opening 121 , and a circle of sealing groove 1211 is formed on the inner side of the movable plug opening 121 , and a sealing ring 7 is provided in the sealing groove 1211 for sealing the movable plug opening 121 when the outer end 42 of the movable plug 4 moves ; a movable plug elastic member 43 is provided between the movable plug 4 and the pilot valve cavity 622 , and the movable plug 4 is pressed by the movable plug elastic member 43 so that the outer end 42 of the movable plug 4 extends out of the movable plug opening 121 and the inner end 41 closes the pilot hole 621 .

[0100] The matching mode of the sealing ring 7 of this embodiment is also different from the structure of Example 2, which shows that the structure of the sealing ring 7 is not limited to this embodiment. When the outer end 42 of the main movable plug 4 moves, the movable plug opening 121 can be sealed to prevent water leakage.

[0101] The corresponding valve body side cover 12 and the pilot valve cover plate 624 may also be provided with a sealing ring 7 for sealing when they are matched with the valve body seat 11 .

[0102] In this embodiment, the outer end 42 of the movable plug 4 moves downward, and the corresponding driving portion 511 of the driving sleeve 51 is also adaptively moved downward.

[0103] Example 4

[0104] As shown in Figures 17 to 21 , the structure of this embodiment is the same as the basic principle and basic structure of the above-mentioned embodiment 3, and the main difference lies in the different structures of the non-electrically driven water outlet component 40, the movable plug 4 and the driving part 511.

[0105] The movable plug 4 of this embodiment is similarly reciprocally mounted within the valve body 1 , with a movable plug elastic member 43 disposed between the movable plug 4 and the valve body 1 . This movable plug elastic member 43 abuts against the movable plug 4 to control the closure of the waterway W. The drive mechanism 5 includes a drive portion 511 . The drive portion 511 and the movable plug 4 are each made of mutually magnetically attractive materials. The drive portion 511 approaches the movable plug 4 to magnetically attract the movable plug 4 and move it, thereby opening the waterway W. The movable plug 4 of this embodiment is made of a magnetic material, and the drive portion 511 is a magnet protruding from the outer wall of the drive sleeve 51 . When the drive sleeve 51 is in the second position, the magnet drives the movable plug 4 to move.

[0106] Specifically, the movable plug 4 can be reciprocated and penetrated in the pilot valve cavity 622; a sealing plug 412 for sealing the pilot hole 621 is provided on the outside of the inner end 41 of the movable plug 4, and the sealing plug 412 is covered on the inner end 41 of the movable plug 4; a movable plug elastic member 43 is provided between the inner side of the outer end 42 of the movable plug 4 and the pilot valve cavity 622, and the movable plug 4 is pushed against the inner end 41 by the movable plug elastic member 43 to close the pilot hole 621.

[0107] In this embodiment, the magnet is an annular magnet with a circular outer wall, and is mounted on a mounting post 516 protruding from the side wall of the drive sleeve 51. The movable plug 4 is cylindrical, with the axial direction of the magnet facing the direction of movement of the movable plug 4. As shown in the figure, the movable plug 4 is located on the left side of the magnet's axial direction. The outer periphery of the outer wall of the magnet is provided with a shielding cover 52, and as shown in the figure, the shielding cover 52 is provided on the front, back, upper and lower peripheries of the magnet.

[0108] The shielding cover 52 includes a lower stop 521 provided on the outer wall of the drive sleeve 51 below the magnet, two oblique upper side stops 522 provided on the front and rear sides of the pilot valve cover 624, and an upper stop 523 provided on the valve body seat 11 and located between the two oblique upper side stops 522. The shielding cover 52 surrounds the magnet and concentrates the magnetic direction, allowing a small magnet to achieve a large driving force, effectively reducing product production costs.

[0109] This embodiment uses magnetic adsorption to replace the protrusion to drive the movable plug 4 to move, and also uses a non-electric drive structure to achieve the opening and closing of the waterway W, which shows that the mutual driving method between the driving part 511 and the movable plug 4 is not limited to this embodiment.

[0110] Existing water outlet components are divided into electrically driven and non-electrically driven ones. Electrically driven water outlet components, such as solenoid valves, control the opening and closing of the movable plug by supplying power to the solenoid valve from an external source. However, this has the disadvantage of requiring a continuous power supply, which limits its use in various scenarios. The present invention, on the other hand, adopts a non-electrically driven approach, meaning that no external power is required to supply power to the water outlet component to open or close the movable plug.

[0111] In summary, the present invention adopts a non-electric drive method by providing a driving mechanism 5 of the pull-out tube 30 to drive the movable plug 4 to open and close the water path W of the shower head 20, thereby simply and effectively completing the functions of pulling out the shower head 20 to control the water flow and resetting to close the water flow. It has a sophisticated structure, stable performance, no need for power supply, strong versatility, and low cost.
