Description

Technical Field

[0001] This utility model relates to the field of shower equipment technology, specifically a water path switching structure for a shower column. Background Technology

[0002] Shower columns, as an important component of modern bathroom facilities, provide users with diverse showering experiences. The water path switching structure is the core component of a shower column that enables switching between various water output modes (such as overhead spray, handheld shower, and bottom faucet). A drawback is that existing shower devices, including overhead and handheld showers, mostly have their water path switching structures located inside the overhead or handheld shower head, resulting in larger and less aesthetically pleasing shower heads. To address this, existing technology (Chinese patent application number: 202122447509.9, authorized announcement date: 2022-05-17) discloses a water path switching structure for a shower column. Pressing the switch button opens the switch valve shaft, allowing water in the back pressure chamber to flow out through the switch hole, releasing the pressure in the back pressure chamber. The switch sealing gasket then moves away from the third sealing port under water pressure, opening the third sealing port. The pressure inside the channel is released, causing the reversing valve shaft to move downward under water pressure and the deformation part to deform to open the second sealing port. The reversing sealing gasket seals the first sealing port. The water inlet channel is connected to the flow channel through the second sealing port. Water from the water inlet channel enters the reversing valve body from the reversing inlet, then flows into the flow channel, passes through the switch valve body and the third sealing port, and enters the handheld water outlet channel. The handheld shower head sprays water, but the overhead shower head does not. Pressing the switch button again causes the switch valve shaft to close the switch hole. There is enough water pressure in the back pressure chamber to make the switch sealing gasket seal the third sealing port. At this time, the flow channel is disconnected from the handheld water outlet channel. The thrust on the reversing sealing gasket is greater than the thrust on the deformation part. The reversing valve shaft moves upward to make the reversing sealing gasket leave the first sealing port and the deformation part seal the second sealing port. Water enters from the water inlet channel, passes through the reversing inlet and the first sealing port, and then enters the overhead shower outlet channel. The overhead shower head sprays water, but the handheld shower head does not.

[0003] Existing technology allows users to switch water circuits by pressing a switch button and using a reversing valve. However, it lacks a notification function, which means that users may not be able to intuitively understand the current water circuit status when switching water circuits, thus requiring repeated attempts, which reduces efficiency and may also affect the user experience. Therefore, we have proposed a water circuit switching structure for shower columns that can effectively solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a water path switching structure for a shower column, so as to solve the problem mentioned in the background art of lacking a reminder function, which makes it impossible for users to intuitively understand the current water path status when switching water paths, thus requiring repeated attempts, resulting in reduced usage efficiency and potentially affecting user experience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water circuit switching structure for a shower column, comprising a switch valve seat, wherein a switching valve is installed inside the switch valve seat, and a first connecting pipe and a second connecting pipe are respectively provided above and below the switch valve seat, and a water inlet pipe is provided at the rear end of the switch valve seat; further comprising: a first flow channel interface and a second flow channel interface are respectively opened on the outer side of the front end of the switching valve, a transmission rod is fixed to the front end of the switching valve, a support cylinder is fixed to the right side and bottom of the switch valve seat, and a fixed contact switch is installed inside the support cylinder, a movable rod is connected to the right side and bottom of the inside of the switch valve seat, and a movable contact switch is fixed to one end of the movable rod, and a first spring is installed between the outer side of the movable rod and the inner wall of the switch valve seat, and a protrusion is fixed to the outer side of the switching valve.

[0006] Preferably, the front end of the water inlet pipe is fixedly connected to a connector, and the outer side of the connector is threaded. The water inlet pipe is threadedly connected to the inner wall of the switch valve seat through the connector.

[0007] Preferably, the first connecting pipe and the second connecting pipe correspond to the positions of the first flow channel interface and the second flow channel interface, the switching valve is rotatably connected inside the switch valve seat, and an LED indicator panel is installed on the top of the switch valve seat.

[0008] Preferably, the front end of the transmission rod extends out of the outer surface of the switch valve seat, and a turntable is fixed to the front end of the transmission rod.

[0009] Preferably, the movable rod is slidably disposed inside the switch valve seat, and one end of the movable rod extends into the inside of the support cylinder. The positions of the movable contact switch and the fixed contact switch correspond to each other, and the end of the movable rod is in contact with the outer side of the protrusion.

[0010] Preferably, a fixing ring is sleeved and fixed on the outer side of the left end of the second connecting pipe, and a receiving groove is opened at equal intervals on the outer side of the fixing ring. A pawl is connected to the inner wall of the receiving groove, and a second spring is installed between the side of the pawl end and the inner wall of the receiving groove. A toothed groove is opened at equal angles on the rear end of the inner wall of the switch valve seat.

[0011] Preferably, the pawl and the tooth groove are meshed, and the pawl is rotatably connected to the inner wall of the receiving groove via a shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the water path switching structure for the shower column adopts a novel structural design, the specific details of which are as follows:

[0013] (1) When the switching valve rotates, the positions of the two protrusions will change. At this time, one protrusion will no longer press the movable rod. The movable rod will be reset under the elastic force of the return spring and will cause the movable contact switch to separate from the fixed contact switch, so that the LED indicator board of the current water circuit will be turned off. The other protrusion will press the other movable rod, so that the other movable rod will cause the movable contact switch to contact the fixed contact switch, and then the LED indicator board of the other water circuit will light up. Thus, the user can quickly understand the water circuit status by simply observing the lighting of the LED indicator board, without having to try or guess.

[0014] (2) Insert the water inlet pipe into the water inlet of the switch valve seat through the connector and tighten it. Then install the first connecting pipe and the second connecting pipe on the first flow channel interface and the second flow channel interface respectively to complete the assembly of the device.

[0015] (3) By rotating the transmission rod clockwise, the transmission rod drives the switching valve to rotate inside the switch valve seat. As the switching valve rotates, its water passage is connected to the second flow channel interface, while the connection with the first flow channel interface is cut off, so that water flows out from the hand shower and the water outlet mode is switched. Furthermore, the switching valve drives the fixing ring to rotate inside the switch valve seat, so that the pawl on the ratchet assembly is squeezed and retracts into the receiving groove. When the user rotates the operating handle to a certain angle, the pawl is reset under the elastic force of the return spring and is locked into the corresponding tooth groove, so that the rotating switching valve can be fixed.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7 The present invention provides the following technical solution: a water path switching structure for a shower column;

[0026] Example 1: To address the lack of a notification function in existing technologies, which prevents users from intuitively understanding the current water circuit status when switching water circuits, thus requiring repeated attempts, reducing efficiency, and potentially impacting user experience, the following solution is disclosed. Please refer to the following for details. Figures 1-3 and Figure 6 and Figure 7As shown, the device includes a switch valve seat 1, inside which a switching valve 3 is installed. A first connecting pipe 4 and a second connecting pipe 5 are fixedly installed at the top and bottom of the switch valve seat 1, respectively. A water inlet pipe 2 is provided at the rear end of the switch valve seat 1, and a connector 7 is fixedly connected to the front end of the water inlet pipe 2. The connector 7 has threads on its outer side, and the water inlet pipe 2 is threadedly connected to the inner wall of the switch valve seat 1 through the connector 7. The device also includes: a first flow channel interface 8 and a second flow channel interface 9 respectively opened on the outer side of the front end of the switching valve 3; support cylinders 13 are fixed to the right side and bottom of the switch valve seat 1, and a fixed contact switch 16 is installed inside the support cylinder 13. A [missing information - likely a device name] is connected to the right side and bottom of the inside of the switch valve seat 1. A movable rod 14 is provided, with a movable contact switch 15 fixed at one end. A first spring 17 is installed between the outer side of the movable rod 14 and the inner wall of the switch valve seat 1. A protrusion 12 is fixed on the outer side of the switching valve 3. The movable rod 14 is slidably disposed inside the switch valve seat 1, with one end of the movable rod 14 extending into the support cylinder 13. The movable contact switch 15 and the fixed contact switch 16 are positioned correspondingly. The end of the movable rod 14 is in contact with the outer side of the protrusion 12. The first connecting pipe 4 and the second connecting pipe 5 are positioned correspondingly to the first flow channel interface 8 and the second flow channel interface 9. The switching valve 3 is rotatably connected inside the switch valve seat 1. An LED indicator panel is installed on the top of the switch valve seat 1.

[0027] In use, the inlet pipe 2 is inserted into the inlet of the switch valve seat 1 through the connector 7 and tightened. Then, the handheld shower head is connected to the second connecting pipe 5, and the top fixed shower head is connected to the first connecting pipe 4, so that water enters the switching valve 3 from the inlet pipe 2 and enters the top fixed shower head from the first flow channel interface 8 and the first connecting pipe 4, thus achieving showering. When the user needs to use the handheld shower head, they only need to rotate the transmission rod 6 clockwise to make the water flow out of the handheld shower head, thereby switching the water path. When the switching valve 3 is rotated, the positions of the two protrusions 12 will change. In this change, one protrusion 12 no longer presses against the movable rod 14. The movable rod 14 returns to its original position under the elastic force of the first spring 17, causing the movable contact switch 15 to separate from the fixed contact switch 16, thus turning off the LED indicator panel of the current water circuit. Meanwhile, the other protrusion 12 presses against the other movable rod 14, causing the other movable rod 14 to drive the movable contact switch 15 to contact the fixed contact switch 16, thereby turning on the LED indicator panel of the other water circuit. This allows the user to quickly understand the water circuit status simply by observing the lighting of the LED indicator panel, without having to probe or guess.

[0028] Example 2: Unlike Example 1, this example uses a rotary switching valve 3 to switch the water outlet mode. See details... Figures 1-4As shown, a transmission rod 6 is fixed to the front end of the switching valve 3. The front end of the transmission rod 6 extends out of the outer surface of the switch valve seat 1, and a turntable is fixed to the front end of the transmission rod 6.

[0029] When the user needs to use the handheld shower head, the transmission rod 6 is rotated clockwise, causing the transmission rod 6 to drive the switching valve 3 to rotate within the switch valve seat 1. As the switching valve 3 rotates, its water passage is connected to the second flow channel interface 9, while the connection with the first flow channel interface 8 is cut off, allowing water to flow out from the handheld shower head, thus realizing the switching of the water output mode.

[0030] Example 3: Unlike Example 2, this example utilizes the elastic force of the second spring 18 to drive the pawl 11 into the corresponding tooth groove 19, thereby limiting and fixing the rotated switching valve 3. See details... Figure 2 and Figure 5 As shown, a fixing ring 10 is sleeved and fixed on the outer side of the left end of the second connecting pipe 5, and a receiving groove 20 is provided at equal intervals on the outer side of the fixing ring 10. A pawl 11 is connected to the inner wall of the receiving groove 20, and a second spring 18 is installed between the side of the pawl 11 end and the inner wall of the receiving groove 20. A toothed groove 19 is provided at equal angles on the rear end of the inner wall of the switch valve seat 1. The pawl 11 and the toothed groove 19 are meshed, and the pawl 11 is rotatably connected to the inner wall of the receiving groove 20 through a shaft.

[0031] When the switching valve 3 drives the fixed ring 10 to rotate inside the switch valve seat 1, multiple pawls 11 are squeezed and retracted into the receiving groove 20 (the second spring 18 is in a compressed state). When the user stops rotating the switching valve 3, the pawls 11 are reset under the elastic force of the second spring 18 and are locked into the corresponding tooth groove 19, so that the rotating switching valve 3 can be fixed.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
