Description

Technical Field

[0001] The invention belongs to the technical field of shower appliances, and in particular relates to a double-water-channel shower pipe. Background Art

[0002] With the continuous improvement of showers, the functions of showers are becoming more and more. In order to provide a more comprehensive cleaning experience and relaxation effect, multiple back water nozzles are usually set on the shower pipe. The back water nozzles can cover the hard-to-reach areas of the user's back, especially those cleaning dead corners of the back. The back water nozzles can also provide an immersive spa experience to help relieve fatigue of the shoulders, neck and back.

[0003] The rear-spray nozzle requires a dual-channel shower pipe design: one channel leads to the top showerhead, and the other to the rear-spray nozzle. A switch button is installed on the shower pipe to switch between the two channels, creating different water flow patterns. Existing switch buttons for water channels are typically seesaw-style buttons, which have certain drawbacks. Low water pressure prevents stable water flow through the button mechanism, and the button may automatically reset due to insufficient pressure, affecting its ability to maintain position and preventing proper water channel switching. Summary of the Invention

[0004] In order to solve the problems in the above-mentioned background technology, the present invention provides a dual-water-channel shower pipe, which drives the two switch rods to move up and down alternately through the lateral movement of the lever, and the switch rods drive the sealing head to move up and down, thereby realizing the switch control function of the two water channels. The switching component has a reliable structure and can accurately realize the press-to-switch action without being affected by water pressure. It improves the problem of the inability to switch the water channel due to automatic resetting of the button due to low water pressure.

[0005] The present invention provides a double-water-path shower pipe, comprising a straight pipe, wherein a water diversion body and a plurality of water outlet bodies are arranged in the straight pipe, and the plurality of water outlet bodies are spliced together, and a plurality of back-spray assemblies are arranged on one side of the straight pipe, and the number of the back-spray assemblies is the same as the number of the water outlet bodies and corresponds one to one, and the water diversion body and the water outlet body are both provided with a first water path and a second water path, and the back-spray assembly is connected with the second water path, and a plug for blocking the top of the second water path is provided at the top of the uppermost water outlet body, and the bottom end of the lowermost water outlet body is connected with the water diversion body, and a switching assembly for switching the water paths is connected at the bottom end of the water diversion body; the switching assembly comprises a main control body, a water inlet is provided at the bottom end of the main control body, a water outlet is provided at the top end of the main control body, and the water outlet is connected with the first water path and the second water path, and two switch rods slide vertically in the main control body, and a sealing head is provided at the top end of the switch rod, and a shift rod slides horizontally in the main control body, and the shift rod drives the two switch rods to move alternately up and down.

[0006] Furthermore, a mounting boss is fixedly connected to one side of the straight tube, and a press-switching valve core is provided in the mounting boss, one end of the shift rod abuts against the press-switching valve core, and a first spring is provided between the other end of the shift rod and the main control body, the first spring pushes the shift rod to move in the direction close to the press-switching valve core, and a second spring is provided between the bottom end of the switch rod and the main control body, and the second spring drives the switch rod to move upward, and the diameter of the end of the shift rod close to the first spring is larger than the diameter of the end of the shift rod close to the press-switching valve core, the circumferential surface of the shift rod with a larger diameter is the open limit surface, and the circumferential surface of the shift rod with a smaller diameter is the close limit surface, and a through hole is provided in the switch rod, and the shift rod passes through the through hole horizontally, the diameter of the through hole is larger than the diameter of the open limit surface, and the inner walls of the two through holes respectively abut against the open limit surface and the close limit surface of the shift rod.

[0007] Furthermore, a guide cone surface is provided between the opening limit surface and the closing limit surface, and at the end of the opening limit surface away from the closing limit surface.

[0008] Furthermore, a first spring slot is provided in the shift lever, the first spring is arranged in the first spring slot, a second spring slot is provided at the bottom end of the switch lever, and the second spring is arranged in the second spring slot.

[0009] Furthermore, one end of the shift lever close to the push-to-switch valve core is set as a semi-spherical head, a guide groove is opened in the push-to-switch valve core, and the semi-spherical head of the shift lever is set in the guide groove.

[0010] Furthermore, a pressure ring is provided between the main control body and the press-to-switch valve core, the lever slides transversely through the pressure ring, a Y-shaped sealing ring is provided between the lever and the pressure ring, a sealing groove is provided on the lever, and the Y-shaped sealing ring is provided in the sealing groove.

[0011] Furthermore, a rectangular anti-rotation limit surface is provided at the bottom end of the switch rod, and an anti-rotation slide groove is opened in the main control body. The switch rod slides vertically in the anti-rotation slide groove and the anti-rotation limit surface cooperates with the groove wall of the anti-rotation slide groove.

[0012] Furthermore, a T-shaped boss is provided at the top of the switch rod, and a T-shaped groove is provided at the bottom of the sealing head. The T-shaped boss matches the T-shaped groove, and the sealing head is installed on the top of the switch rod through the T-shaped boss and the T-shaped groove.

[0013] Furthermore, the back spray assembly includes a nozzle shell and a water outlet nozzle. The nozzle shell extends into the straight pipe and is detachably mounted on the water outlet body. The water outlet nozzle is detachably mounted on the nozzle shell.

[0014] Furthermore, the bottom end of the plug is connected to the water outlet and blocks the second water channel, and the top end of the plug is provided with a water flow channel, which is connected to the first water channel.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) In the initial state, the inner wall of the through hole of one switch rod abuts against the open limit surface of the lever, and the inner wall of the through hole of the other switch rod abuts against the close limit surface of the lever. Since the diameter of the open limit surface is larger than the diameter of the close limit surface, the switch rod abutting against the open limit surface will press the second spring downward under the restriction of the open limit surface. Therefore, there is a gap between the sealing head at the top of the switch rod abutting against the open limit surface and the water diversion body, that is, the first water path is opened; while the switch rod abutting against the close limit surface will not be restricted by the lever, so the second spring will push the switch rod upward, so that the sealing head at the top of the switch rod abuts against the water diversion body, thereby sealing the second water path.

[0016] When the water path needs to be switched, the push-to-switch valve core is pressed. The push-to-switch valve core switches state, and the first spring pushes the lever toward the push-to-switch valve core, that is, the lever moves to the right. During this movement, the switch rod abutting the open limit surface gradually loses its restraint, and the second spring pushes the switch rod upward. The sealing head at the top of the switch rod presses against the water diversion body, thereby sealing the first water path. At the same time, the switch rod abutting the close limit surface gradually moves to the open limit surface. With the restraint of the open limit surface, the switch rod presses the second spring downward, and the sealing head at the top of the switch rod also disengages from the water diversion body, opening the second water path and completing the water path switching. This switching assembly has a reliable structure, can accurately implement the push-to-switch action, and is not affected by water pressure. This solves the problem of the key automatically resetting due to low water pressure, resulting in the inability to switch water paths.

[0017] (2) The guide cone gradually shrinks in diameter from the open limit surface to the closed limit surface, so that when the lever moves, the switch rod can smoothly switch to the corresponding limit surface, improving the smoothness of the operation when switching the waterway and preventing jamming during the switching process.

[0018] (3) The cooperation between the anti-rotation limit surface and the anti-rotation slide groove can limit the rotation of the switch rod, ensuring that the switch rod can only move up and down but cannot rotate, thereby ensuring that the contact action between the lever and the switch rod is smooth.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0022] The following is combined with Figure 1 To the attached Figure 10 The present invention is described in detail with reference to specific embodiments.

[0023] Reference Figures 1-10The present invention provides a double-water-path shower pipe, comprising a straight pipe 1, wherein a water diversion body 2 and a plurality of water outlet bodies 3 are provided in the straight pipe 1, wherein the plurality of water outlet bodies 3 are spliced together, and a plurality of back-spray assemblies 4 are provided on one side of the straight pipe 1, wherein the number of the back-spray assemblies 4 is the same as the number of the water outlet bodies 3 and corresponds one to one, and a first water path 5 and a second water path 6 are provided in both the water diversion body 2 and the water outlet body 3, wherein the back-spray assembly 4 is connected to the second water path 6, and the first water path 5 extends to the top of the straight pipe 1, thereby supplying water to the top spray shower; a plug 7 for blocking the top of the second water path 6 is provided at the top of the uppermost water outlet body 3, and a plug 7 for blocking the top of the second water path 6 is provided at the bottom of the water outlet body 3 3 is connected to the water diversion body 2, and the bottom end of the water diversion body 2 is connected to a switching assembly 8 for switching the water path; the switching assembly 8 includes a main control body 80, a water inlet 800 is provided at the bottom end of the main control body 80, the bottom end of the main control body 80 is connected to the shower body, and a water outlet 801 is provided at the top end of the main control body 80, and the water outlet 801 is connected to the first water path 5 and the second water path 6. There are two switch rods 81 that slide vertically in the main control body 80, and the top end of the switch rods 81 is provided with a sealing head 82 for blocking the water path. A shift rod 83 slides horizontally in the main control body 80, and the shift rod 83 drives the two switch rods 81 to move up and down alternately.

[0024] It should be noted that the present application does not limit the connection method between the water outlet bodies 3 and the connection method between the water diversion body 2 and the water outlet body 3. Either a threaded connection method or a snap connection method can be used.

[0025] Specifically, one side of the straight pipe 1 is fixedly connected to a mounting boss 84, and a press-switching valve core 85 is provided in the mounting boss 84. The press-switching valve core 85 is a prior art, so the structure of the press-switching valve core 85 is not described in detail; one end of the shift rod 83 abuts against the press-switching valve core 85, and a first spring 86 is provided between the other end of the shift rod 83 and the main control body 80. The first spring 86 pushes the shift rod 83 to move toward the direction of the press-switching valve core 85, and a second spring 87 is provided between the bottom end of the switch rod 81 and the main control body 80. The second spring 87 drives To move the switch rod 81 upward, the diameter of the end of the lever rod 83 close to the first spring 86 is larger than the diameter of the end of the lever rod 83 close to the pressing switch valve core 85. The circumferential surface of the lever rod 83 with a larger diameter is the open limit surface 830, and the circumferential surface of the lever rod 83 with a smaller diameter is the close limit surface 831. A through hole 810 is provided in the switch rod 81, and the lever rod 83 passes through the through hole 810 horizontally. The diameter of the through hole 810 is larger than the diameter of the open limit surface 830, and the inner walls of the two through holes 810 respectively abut against the open limit surface 830 and the close limit surface 831 of the lever rod 83.

[0026] In the initial state, the inner wall of the through hole 810 of one switch rod 81 abuts against the open limit surface 830 of the shift rod 83, and the inner wall of the through hole 810 of the other switch rod 81 abuts against the close limit surface 831 of the shift rod 83. Since the diameter of the open limit surface 830 is larger than the diameter of the close limit surface 831, the switch rod 81 abutting against the open limit surface 830 will press the second spring 87 downward under the restriction of the open limit surface 830. Therefore, there is a gap between the sealing head 82 at the top of the switch rod 81 abutting against the open limit surface 830 and the water diversion body 2, that is, the first waterway 5 is opened; and the switch rod 81 abutting against the close limit surface 831 will not be restricted by the shift rod 83, so the second spring 87 will push the switch rod 81 to move upward, so that the sealing head 82 at the top of the switch rod 81 abuts against the water diversion body 2, thereby sealing the second waterway 6.

[0027] When the waterway needs to be switched, the push-to-switch valve core 85 is pressed, and the push-to-switch valve core 85 switches state. The first spring 86 pushes the lever 83 toward the push-to-switch valve core 85, that is, the lever 83 moves to the right. During the movement of the lever 83, the switch rod 81 abutting against the open limit surface 830 gradually loses the restraint of the lever 83, and the second spring 87 pushes the switch rod 81 upward. The sealing head 82 at the top of the switch rod 81 presses against the water diversion body 2, thereby sealing the first waterway 5. At the same time, the switch rod 81 abutting against the close limit surface 831 gradually moves to the open limit surface 830. With the restraint of the open limit surface 830, the switch rod 81 presses the second spring 87 downward, and the sealing head 82 at the top of the switch rod 81 also disengages from the water diversion body 2, that is, opening the second waterway 6, thereby completing the waterway switching. The switching assembly 8 has a reliable structure, can accurately realize the push-to-switch action, and is not affected by water pressure. This solves the problem of the key automatically resetting due to low water pressure, which causes the waterway to be unable to switch.

[0028] A guide cone 832 is provided between the open limit surface 830 and the close limit surface 831, as well as at the end of the open limit surface 830 away from the close limit surface 831. The guide cone 832 gradually reduces in diameter from the open limit surface 830 to the close limit surface 831, so that when the lever 83 moves, the switch rod 81 can be smoothly switched to the corresponding limit surface, thereby improving the operational smoothness during water channel switching and preventing jamming during the switching process.

[0029] A first spring slot 833 is defined within the lever 83, and the first spring 86 is disposed within the first spring slot 833. A second spring slot 811 is defined at the bottom end of the switch lever 81, and the second spring 87 is disposed within the second spring slot 811. The first spring slot 833 and the second spring slot 811 are used to position the first spring 86 and the second spring 87, thereby ensuring that the first spring 86 can be compressed and released normally within the first spring slot 833 and the second spring 87 can be released normally within the second spring slot 811.

[0030] The end of the lever 83 near the push-switch valve core 85 is provided with a semi-spherical head. A guide groove 850 is defined in the push-switch valve core 85, and the semi-spherical head of the lever 83 is disposed in the guide groove 850. The lever 83 contacts the push-switch valve core 85 via the semi-spherical head, which reduces the contact area between the lever 83 and the push-switch valve core 85, thereby preventing adsorption.

[0031] A pressure ring 88 is disposed between the main control body 80 and the push-to-switch valve core 85. The lever 83 slides transversely through the pressure ring 88. A Y-shaped sealing ring 89 is disposed between the lever 83 and the pressure ring 88. The lever 83 is provided with a sealing groove 834, and the Y-shaped sealing ring 89 is disposed within the sealing groove 834. The pressure ring 88 further restricts the movement of the lever 83, ensuring that the lever 83 can move laterally without deflection. The Y-shaped sealing ring 89 between the lever 83 and the pressure ring 88 seals off water in the main control body 80, preventing it from seeping into the push-to-switch valve core 85.

[0032] A rectangular anti-rotation limit surface 812 is provided at the bottom end of the switch lever 81. An anti-rotation slot 802 is provided within the main control body 80. The switch lever 81 slides vertically within the anti-rotation slot 802, with the anti-rotation limit surface 812 engaging the walls of the slot 802. The interaction between the anti-rotation limit surface 812 and the slot 802 restricts rotation of the switch lever 81, ensuring that the switch lever 81 can only move up and down, not rotate. This ensures smooth contact between the lever 83 and the switch lever 81.

[0033] The top of the switch rod 81 is provided with a T-shaped boss 813, and the bottom of the sealing head 82 is provided with a T-shaped groove 820. The T-shaped boss 813 and the T-shaped groove 820 mate with each other, and the sealing head 82 is mounted on the top of the switch rod 81 via the T-shaped boss 813 and the T-shaped groove 820. The design of the T-shaped boss 813 effectively holds the sealing head 82, preventing it from being displaced by water flow and improving its stability. Furthermore, the sealing head 82 is made of rubber, which utilizes rubber's elastic compression and good water-tightness properties to further ensure a water-blocking and leak-tight seal.

[0034] The back spray assembly 4 includes a nozzle housing 40 and a water outlet nozzle 41. The nozzle housing 40 extends into the straight pipe 1 and is detachably mounted on the water outlet body 3. The water outlet nozzle 41 is detachably mounted on the nozzle housing 40. This application does not limit the manner in which the nozzle housing 40 and the water outlet nozzle 41 are detachable. They can be connected by thread or by snap, all within the scope of protection of this application. The detachable installation of the nozzle housing 40 and the water outlet nozzle 41 facilitates subsequent maintenance and replacement. At the same time, different types of back spray assemblies 4 can be replaced according to user needs, thereby achieving more functions.

[0035] The bottom end of the plug 7 is connected to the water outlet 3 and blocks the second water channel 6. The top end of the plug 7 defines a water flow passage 70 that communicates with the first water channel 5. The bottom end of the plug 7 blocks the second water channel 6, allowing water in the second water channel 6 to be sprayed out through the rear spray assembly 4. The water in the first water channel 5 flows upward through the water flow passage 70 within the plug 7, passing through the plug 7, and out of the top spray head at the top of the straight pipe 1.

[0036] Finally, it should be noted that sealing rings are provided between each connecting component in the present application to ensure that water flow and water leakage will not occur in the shower pipe.

[0037] The present invention is further described above with the aid of specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
