Description

Technical Field

[0001] This utility model belongs to the technical field of bathroom equipment, and specifically refers to a top spray connection structure. Background Technology

[0002] In bathroom fixtures, overhead shower heads are a common type of shower device, and the design of their connection structure is crucial for ease of use, stability, and safety.

[0003] In existing technology, most overhead showers have a single water inlet and a ball joint to secure them to the riser bar, allowing for angle adjustment. As people's demands for a better shower experience continue to increase, many overhead showers with dual water inlets have appeared on the market, enabling adjustable water flow modes. However, the dual water inlet structure renders the ball joint unusable, meaning it cannot be used to connect the showerhead to the riser bar's water outlet. Utility Model Content

[0004] The main purpose of this utility model is to provide a top spray connection structure that solves the problems existing in the prior art, and is compatible with the features of angle adjustment and dual water channels, making the product more functional.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A shower head connection structure includes a shower column and a shower head assembly; the shower column includes an outer tube and an inner tube disposed within the outer tube; the shower head assembly includes a housing, a water seal base, a water outlet panel, a water outlet device, a ball joint, and a hose; the water seal base is fitted inside the housing, with its inlet pipe extending upward through the housing; the water outlet panel is sealed to the water seal base and has several water outlet holes; the water outlet device is mounted on the water outlet panel; the ball joint is rotatably fitted with the port of the inlet pipe in a dynamic sealing manner and is sealed to the water outlet end of the outer tube; the hose passes through the ball joint, with its two ends respectively connected to the inner tube and the water outlet device.

[0007] The water outlet panel and the water sealing base form a water passage cavity, and the water inlet pipe and the water outlet hole are both connected to the water passage cavity.

[0008] An installation cavity is provided at the axis of the water outlet panel, and the installation cavity is provided with a water inlet; the water outlet device is installed in the installation cavity, and its circumference is sealed with the inner wall of the installation cavity; the water outlet end of the hose is sealed and inserted into the water inlet.

[0009] Preferably, the water outlet device is an aerator.

[0010] The inlet end of the water inlet pipe is provided with an annular step, and a sealing ring is provided on the annular step; the sealing ring is dynamically sealed and fits on the circumference of the spherical joint.

[0011] The spherical connector has a C-ring fitted on its circumference. The C-ring is limited by a locking nut to fit into the water inlet end of the water inlet pipe. The locking nut is threaded to the end of the water inlet end. The C-ring clamps the spherical connector with the end face of the water inlet pipe.

[0012] The spherical connector is threaded to the outlet end of the outer pipe.

[0013] After adopting the above technical solution, the present invention has the following technical effects:

[0014] This utility model's shower column has an outer pipe and an inner pipe. Water can be supplied to the water outlet panel and the water outlet device through two water paths: one between the outer pipe and the inner pipe, and the other inside the inner pipe, thus achieving a dual water path function. The water path switching between the water source and the top spray assembly can be controlled by a button on the shower unit at the lower end of the shower column (this is an existing function of the shower unit). The two water paths are separated by a flexible hose at the ball joint. The inner pipe only supplies water to the water outlet device, and the flexible hose can adapt to the swing of the top spray assembly, allowing the top spray assembly to achieve an angle adjustment function through the ball joint.

Detailed Implementation

[0022] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0023] refer to Figure 1-3 As shown, this utility model discloses a top spray connection structure, including a shower column 1 and a top spray assembly 2;

[0024] The shower column 1 includes an outer pipe 11 and an inner pipe 12 disposed inside the outer pipe 11;

[0025] The overhead spray assembly 2 includes a housing 21, a water seal base 22, a water outlet panel 23, a water outlet device 24, a ball joint 25, and a hose 26. The water seal base 22 is fitted inside the housing 21, and its inlet pipe 221 extends upward through the housing 21. The water outlet panel 23 is sealed to the water seal base 22 and is provided with several water outlet holes 231, enabling the overhead spray assembly 2 to function as a regular shower head, i.e., to output shower water. The water outlet device 24 is installed on the water outlet panel 23, enabling the overhead spray assembly 2 to have special functions, such as blade water, rotating water, and aerated water. The ball joint 25 is dynamically and rotatably fitted to the port of the inlet pipe 221 and is sealed to the outlet end of the outer pipe 11. The hose 26 passes through the ball joint 25, and its two ends are respectively connected to the inner pipe 12 and the water outlet device 24.

[0026] Through the above solution, the shower column 1 of this utility model has an outer pipe 11 and an inner pipe 12. Water can be supplied to the water outlet panel 23 and the water outlet device 24 through two water paths: the one between the outer pipe 11 and the inner pipe 12, and the one inside the inner pipe 12, respectively, thus realizing a dual water path function (see [reference]). Figure 5 The water path switching between the water source and the overhead shower assembly 2 can be controlled by a button on the shower head 3 at the lower end of the shower column 1 (this is an existing function of the shower head); the two water paths are separated at the ball joint 25 by a hose 26, with the inner pipe 12 supplying water only to the water outlet 24, and the hose 26 can adapt to the swaying of the overhead shower assembly 2 (see...). Figure 4 This allows the top spray assembly 2 to achieve angle adjustment via the ball joint 25.

[0027] The following are specific embodiments of the present invention.

[0028] The water outlet panel 23 and the water sealing seat 22 form a water passage cavity a, and the water inlet pipe 221 and the water outlet hole 231 are both connected to the water passage cavity a.

[0029] An installation cavity 232 is provided at the axis of the aforementioned water outlet panel 23, and an inlet 233 is provided in the installation cavity 232; the water outlet device 24 is installed in the installation cavity 232, and its circumference is sealed with the inner wall of the installation cavity 232; the water outlet end of the hose 26 is sealed and inserted into the inlet 233.

[0030] Furthermore, the aforementioned water outlet device 24 is an aerator.

[0031] The inlet end of the aforementioned water inlet pipe 221 is provided with an annular step 222, and a sealing ring 27 is provided on the annular step 222; the sealing ring 27 is dynamically and sealingly fitted onto the circumferential surface of the spherical joint 25. This allows for an increase in the swing angle of the top spray assembly 2 (reaching over 20°), improving space utilization.

[0032] The circumferential surface of the ball joint 25 is fitted with a C-ring 28. The C-ring 28 is limited by a locking nut 29 to fit into the water inlet end of the water inlet pipe 221. The locking nut 29 is threadedly connected to the end of the water inlet end 221. The C-ring 28 and the end face of the water inlet pipe 221 clamp the ball joint 25 so that the ball joint 25 can swing without disengaging from the end face of the water inlet pipe 221.

[0033] The aforementioned ball joint 25 is threadedly connected to the outlet end of the outer pipe 11 for easy disassembly and assembly.

[0034] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
