Description

Technical Field

[0001] This utility model belongs to the field of shower column technology, and specifically refers to a novel shower column structure. Background Technology

[0002] In existing technology, shower columns come in a variety of designs. Commonly used shower columns typically have an upper water outlet leading to the overhead showerhead and a lower water outlet leading to the handheld showerhead. Generally, a switching valve is used to switch the water flow between the overhead showerhead and the handheld showerhead, thus effectively controlling and switching the water flow.

[0003] Currently, most shower columns sold on the market are made of copper and its alloys, and their surfaces are electroplated to prevent rust. However, existing shower columns have the following defects during use:

[0004] (1) Because copper has excellent thermal conductivity, if users accidentally touch the shower column when using high-temperature water, they are very likely to be scalded, which poses a certain safety hazard.

[0005] (2) Copper alloys may contain lead, which will leach into the water when water comes into direct contact with these materials; at the same time, residual chlorine in tap water that uses chlorine as a disinfectant will accelerate the aging of faucets and lead leaching.

[0006] (3) The water in the shower column can easily exchange heat with the outside through the copper pipes of the shower column itself, especially in cold environments, which can easily cause heat loss. Utility Model Content

[0007] The main purpose of this utility model is to provide a new type of shower column structure to solve the problems existing in the prior art and achieve anti-scalding and lead-free functions.

[0008] To achieve the above objectives, the solution of this utility model is:

[0009] A novel shower column structure includes an outer tube assembly and an inner tube assembly. The outer tube assembly includes an upper outer tube and a lower outer tube, each integrally formed. The upper outer tube includes an upper outer bend and an upper outer straight tube. The upper end of the upper outer bend is used to connect to the overhead shower, and the lower end of the upper outer straight tube is telescopically fitted within the upper end of the lower outer tube. The inner tube assembly includes an upper inner bend, an upper inner straight tube, and a lower inner tube. Both the upper inner bend and the upper inner straight tube are extruded from PE material, and their adjacent ends are connected by a connector. The upper inner bend... The upper end is provided with a first connector for connecting to the top spray, and the first connector is fixed relative to the upper end of the upper outer bend; the lower end of the upper inner straight pipe is provided with a second connector fixed relative to the lower end of the upper outer straight pipe; the lower inner pipe is made of plastic, and its upper end is telescopically fitted inside the upper end of the upper inner straight pipe, and is provided with a third connector that dynamically seals against the inner wall of the upper inner straight pipe; the lower end of the lower inner pipe is provided with a fourth connector fixed relative to the lower end of the lower outer pipe, and the fourth connector is used to connect to a water source.

[0010] The outer tube assembly is made of metal.

[0011] The upper end of the upper outer bend is provided with an external thread to achieve a threaded connection with the top spray water inlet.

[0012] The inner wall of the upper end of the lower outer tube is provided with a limiting slope; a C-shaped sleeve through which the upper outer straight tube passes is movably fitted on the limiting slope; the C-shaped sleeve is engaged with a locking nut at the upper end of the lower outer tube by a threaded connection, so as to lock or loosen the upper outer straight tube.

[0013] The connectors are connected and fixed to the ends of the upper inner bend and the upper inner straight pipe respectively using laser welding.

[0014] The first connector is connected and fixed to the upper end of the upper inner bend using injection molding or laser welding. The second connector is connected and fixed to the lower end of the upper inner straight pipe using injection molding or laser welding. The third connector is connected and fixed to the upper end of the lower inner pipe using injection molding or laser welding. The fourth connector is connected and fixed to the lower end of the lower inner pipe using injection molding or laser welding.

[0015] The first connector and the second connector are respectively fixed to the upper end of the upper outer bend and the lower end of the upper outer straight pipe by a C-shaped retaining ring.

[0016] A fixing member is fixedly connected to the outer circumferential surface between the two ends of the lower inner tube, and the fixing member is fixed relative to the inner wall of the lower outer tube.

[0017] Preferably, the fastener is connected and fixed to the lower inner tube by laser welding.

[0018] Preferably, the fourth connector and the fixing member are respectively fixed to the lower inner tube by a screw; the screw passes through the outer circumferential surface of the lower inner tube and is screwed into the fourth connector or the fixing member.

[0019] After adopting the above technical solution, the present invention has the following technical effects:

[0020] This invention, by setting an inner pipe assembly inside the outer pipe assembly, allows water to be supplied directly to the top sprayer through the inner pipe assembly without contacting the metal outer pipe assembly. This ensures water quality, improves safety, and achieves lead removal during use. Simultaneously, the outer and inner pipe assemblies are separated by air, preventing direct contact and heat conduction and exchange, thus preventing heat loss and achieving an anti-scalding effect. The structural design between the outer and inner pipe assemblies ensures that the upper inner curved pipe and upper inner straight pipe can maintain synchronized telescopic movement with the upper outer pipe.

Detailed Implementation

[0035] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0036] refer to Figure 1-12 As shown, this utility model discloses a novel shower column structure, including an outer pipe assembly 1 and an inner pipe assembly 2;

[0037] The outer tube assembly 1 includes an upper outer tube 11 and a lower outer tube 12, which are integrally formed. The upper outer tube 11 includes an upper outer bend 111 and an upper outer straight tube 112. The upper end of the upper outer bend 111 is used to connect to the top spray 3, and the lower end of the upper outer straight tube 112 is telescopically fitted inside the upper end of the lower outer tube 12.

[0038] The inner pipe assembly 2 includes an upper inner bend 21, an upper inner straight pipe 22, and a lower inner pipe 23. Both the upper inner bend 21 and the upper inner straight pipe 22 are extruded from PE (polyethylene) material to ensure the same inner diameter, and their adjacent ends are connected by a connector 24. The upper end of the upper inner bend 21 is provided with a first connector 25 for connecting to the top spray 3, and the first connector 25 is fixed relative to the upper end of the upper outer bend 111. The lower end of the upper inner straight pipe 22 is provided with a second connector 26 that is fixed relative to the lower end of the upper outer straight pipe 112. The lower inner pipe 23 is made of plastic, and its upper end is telescopically fitted inside the upper end of the upper inner straight pipe 22, and is provided with a third connector 27 that is dynamically sealed to the inner wall of the upper inner straight pipe 22. The lower end of the lower inner pipe 23 is provided with a fourth connector 28 that is fixed relative to the lower end of the lower outer pipe 12. The fourth connector 26 is used to connect to a water source, such as a shower installed on the wall or a water supply pipe embedded in the wall.

[0039] Through the above solution, this utility model sets an inner pipe assembly 2 inside the outer pipe assembly 1, and the water flow is directly supplied to the top spray 3 through the inner pipe assembly 2 without contacting the outer pipe assembly 1, which is made of metal. This ensures water quality, improves safety, and achieves the purpose of lead removal during use. At the same time, the outer pipe assembly 1 and the inner pipe assembly 2 are separated by air and do not come into direct contact, which can avoid heat conduction and heat exchange, prevent heat loss, and achieve a scalding effect. The structural design between the outer pipe assembly 1 and the inner pipe assembly 2 can ensure that the upper inner bend 21 and the upper inner straight pipe 22 can maintain a synchronous telescopic movement with the upper outer pipe 11.

[0040] The following are specific embodiments of the present invention.

Specifically, when the locking nut 5 is screwed down, the C-shaped sleeve 4 is tightly fitted on the limiting inclined surface 121, thereby contracting inward under the action of the inclined surface to lock the upper outer straight tube 112; conversely, the upper outer straight tube 112 is not locked and can move up and down relative to the lower outer tube 12. In this embodiment, the upper end of the lower outer tube 12 is provided with an internal thread 122 for the locking nut 5 to be threadedly connected.

The fixing member 29 is fixed relative to the inner wall of the lower outer tube 12, which can prevent the lower inner tube 23 from shaking due to the movement of water flow during the water passage process, thereby achieving the noise reduction function.

[0048] Furthermore, the aforementioned fastener 29 is connected and fixed to the lower inner tube 23 using a laser welding process.

[0049] At the same time, refer to Figure 8 , 9 As shown, the fourth connector 28 and the fixing member 29 are respectively fixed to the lower inner tube 23 by a screw 7; the screw 7 is inserted through the outer peripheral surface of the lower inner tube 23 and screwed into the fourth connector 28 or the fixing member 29.

[0050] The third connector 27 is provided with several sealing rings on its circumferential surface to achieve dynamic sealing with the inner wall of the upper inner straight pipe 22.
