Description

Technical Field

[0001] The utility model relates to the technical field of shower columns, in particular to a shower column provided with a cold water reflux structure. Background Art

[0002] In the development of modern shower equipment, shower columns are an important component, and their performance and functions directly affect the user's shower experience. However, existing shower columns have some significant problems during use.

[0003] When it comes to hot water supply, overheating is common due to factors such as the dwell time of hot water in pipes, unstable hot water supply, and fluctuations in heating equipment performance. When users turn on the shower head, the initial spray of overheated water can cause severe skin irritation or even burns. This is particularly harmful to children, the elderly, and those with sensitive skin. Furthermore, overheating can not only harm the body but also damage sensitive components within the shower column, shortening its lifespan.

[0004] For example, a new type of shower column with publication number CN106859449A includes a main column and a top spray, one end of the top spray is locked to the upper end of the main column by screws, and the top spray is provided with a top spray outlet plate fixed by a pressure strip, and each water outlet is connected to a water outlet hose, and the hot and cold switching valve includes a hot water inlet and a hot and cold water inlet, and the hot water inlet and the hot and cold water inlets are both connected to a water inlet hose, and the main column is also provided with a shower outlet connector and a lower faucet outlet pipe, and the main column and the top spray are connected with screws, which is convenient for disassembly and assembly, and the overall shower column is directly hung on the wall through the mounting holes on the hanging strip, which is more convenient to install and can be completed by one person; at the same time, the main column uses a water outlet hose and a water inlet hose, which is more convenient to connect and has a longer service life of the hose.

[0005] The above-mentioned new shower column requires manual adjustment of the water temperature during use, and cannot automatically return the cold water, which can easily burn the skin. However, there are other problems. For example, in terms of disassembly and assembly of the shower head, the existing shower column design has many inconveniences. Its structure is complex, and the fixing method often relies on multiple screws, clips or special tools, which makes the disassembly and assembly process extremely cumbersome. Moreover, due to the lack of clear operating instructions and standardized design, users often feel confused and at a loss when disassembling and assembling. For those users who want to frequently change shower heads to meet different shower needs, or who need to clean and maintain the shower head regularly, the existing shower column design undoubtedly brings them great inconvenience. Utility Model Content

[0006] The purpose of the utility model is to provide a shower column with a cold water return structure to solve the problems of excessively high water temperature in the shower column, which may cause skin burns, and the inconvenience of replacing and maintaining the shower head, as mentioned in the background art.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a shower column with a cold water return structure, comprising a hot water pipe and a return pipe installed on the right side of the hot water pipe, the other end of the hot water pipe being installed on the water heater, and a cold water pipe being installed on the right side of the return pipe, and the other end of the cold water pipe being installed on the water cooler, and a mixing pipe being installed above the hot water pipe, a fixing box being installed on the upper end of the return pipe, and a fixing groove being opened on the upper part of the fixing box, the fixing groove inside the fixing box being "L"-shaped and passing through the return pipe, and a cold water return mechanism being provided inside the fixing box;

[0008] A fixed pipe is installed on the outer side of the upper end of the mixing pipe, and a shower head is fixedly installed on the fixed pipe. A quick assembly and disassembly mechanism is arranged inside the fixed pipe.

[0010] Furthermore, a return spring is fixedly installed on the upper part of the fixed box, and the other end of the return spring is installed on the rack. A rotating shaft is rotatably installed inside the fixed box, and the rotating shaft is installed through the return pipe.

[0011] Furthermore, a rotating gear is fixedly installed on the upper end of the rotating shaft, and the rack and the rotating gear form an engaged transmission structure. A driving gear is fixedly installed in the middle of the rotating shaft, and the driving gear is installed inside the return pipe.

[0012] Furthermore, a sealing plug is nested and installed on the right side of the reflux pipe, and a semicircular tooth is provided on the left side of the sealing plug, and the driving gear and the sealing plug form an engaged transmission structure, and a sealing ring is installed on the right side of the sealing plug.

[0013] Furthermore, the quick disassembly and assembly mechanism includes a clamping lever installed inside the fixed tube, and four clamping levers are evenly distributed with the fixed tube as the rotation center, and an extrusion spring is installed inside the fixed tube, and the extrusion spring is embedded in the clamping lever.

[0014] Furthermore, the mixing tube has an upper docking platform movably installed at the upper end, and a lower docking platform fixedly installed below the upper end of the mixing tube, and the lower docking platform is below the upper docking platform, and the upper docking platform and the lower docking platform correspond to the clamping bar, and a sealing gasket is fixedly installed at the lower end of the lower docking platform.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the shower column provided with a cold water return structure;

[0016] 1. When hot water appears in the hot water pipe and flows upward, if the water temperature is too high, the airbag expands due to the heat. The airbag expands regularly within the specific shape of the fixed box. As the airbag expands, it pushes the rack to the right. During the movement of the rack, the meshing action drives the rotating gear. The driving gear meshes with the sealing plug to move. At this time, the sealing plug moves to the right along the return pipe, opening the return pipe opening. This allows water from the cold water pipe to flow into the return pipe, mix with the hot water in the hot water pipe, and finally flow out of the mixing pipe. In terms of water temperature control, the innovative linkage structure of the airbag, rack, and sealing plug accurately and effectively solves the problem of overheating.

[0017] Furthermore, in terms of water temperature control, the problem of overheated water has been successfully solved, providing users with a comfortable and safe shower water temperature at all times, greatly improving the shower experience.

[0018] Furthermore, this not only ensures that users can always enjoy a comfortable and safe water temperature during showering, avoiding the risk of scalding, but also greatly improves the comfort and pleasure of showering, and provides more considerate protection for all kinds of people, especially children, the elderly and those with sensitive skin.

[0019] 2. If the shower head is damaged or clogged, first push the shower head upward; this will then move the fixed tube upward. The fixed tube further drives the lever upward. As the lever moves upward, its end presses against the outer surface of the upper docking platform. This pressure causes the lever to press outward against the extrusion spring, causing the lever to shift in position. Once the lever reaches the upper end of the docking platform, pull the shower head downward to remove it from the connection. The unique docking boss and slot design greatly simplifies the disassembly and assembly process.

[0020] Furthermore, users can easily complete the disassembly and assembly of the shower head without the aid of complex tools or professional skills. This allows users to quickly replace different types of shower heads according to personal preferences to meet diverse shower needs, such as massage, spray, etc. At the same time, convenient disassembly and assembly also facilitates regular and thorough cleaning of the shower head, effectively preventing bacterial growth and ensuring shower hygiene.

Obviously, the embodiments described 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 creative efforts are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figures 1-6 The utility model provides the following technical solution: a shower column with a cold water return structure, comprising a hot water pipe 1, a return pipe 2, a cold water pipe 3, a mixing pipe 4, a fixing box 5, a fixing pipe 6, a shower head 7, an air bag 8, a rack 9, a return spring 10, a rotating shaft 11, a rotating gear 12, a driving gear 13, a sealing plug 14, a sealing ring 15, a clamping lever 16, an extrusion spring 17, an upper docking platform 18, a lower docking platform 19 and a sealing gasket 20.

[0030] It includes a hot water pipe 1 and a return pipe 2 installed on the right side of the hot water pipe 1. The other end of the hot water pipe 1 is installed on the water heater, and a cold water pipe 3 is installed on the right side of the return pipe 2, and the other end of the cold water pipe 3 is installed on the water cooler. A mixing pipe 4 is installed above the hot water pipe 1, and a fixing box 5 is installed on the upper end of the return pipe 2. A fixing groove is opened on the upper part of the fixing box 5. The fixing groove inside the fixing box 5 is "L"-shaped, and the fixing groove inside the fixing box 5 passes through the return pipe 2. A cold water return mechanism is provided inside the fixing box 5;

[0031] A fixed pipe 6 is installed on the outer side of the upper end of the mixing pipe 4, and a shower head 7 is fixedly installed on the fixed pipe 6. A quick assembly and disassembly mechanism is provided inside the fixed pipe 6.

[0032] The cold water return mechanism includes an airbag 8 bonded to the interior of a stationary box 5. A rack 9 is mounted on the interior of the stationary box 5, with a guide groove defined on the front of the box 5 and a guide block defined on the front of the rack 9. The guide groove in the box 5 corresponds to the guide block on the front of the rack 9. A return spring 10 is fixedly mounted on the top of the stationary box 5, with its other end attached to the rack 9. A rotating shaft 11 is rotatably mounted inside the box 5 and extends through the return pipe 2.

[0033] A rotating gear 12 is fixedly mounted on the upper end of the rotating shaft 11, and the rack 9 and the rotating gear 12 form a meshing transmission structure. A driving gear 13 is fixedly mounted in the middle of the rotating shaft 11 and is installed inside the return pipe 2. A sealing plug 14 is nested and installed on the right side of the return pipe 2. The left side of the sealing plug 14 has semicircular straight teeth. The driving gear 13 and the sealing plug 14 form a meshing transmission structure, and a sealing ring 15 is installed on the right side of the sealing plug 14.

[0034] When hot water appears in the hot water pipe 1 and flows upward, if the hot water temperature is too high, the airbag 8 will expand due to the heat. The airbag 8 expands regularly under the constraints of the specific shape inside the fixed box 5. As the airbag 8 expands, it pushes the rack 9 to move to the right. During the movement of the rack 9, the rotating gear 12 is driven to rotate by meshing. The rotating gear 12 is connected to the rotating shaft 11, thereby driving the rotating shaft 11 to rotate. The rotating shaft 11 further drives the driving gear 13 to rotate. The driving gear 13 drives the sealing plug 14 to move through meshing. At this time, the sealing plug 14 moves to the right along the return pipe 2, opening the pipe mouth of the return pipe 2. In this way, the water in the cold water pipe 3 can flow into the return pipe 2, mix with the hot water in the hot water pipe 1, and finally flow out of the mixing pipe 4.

A sealing gasket 20 is fixedly mounted on the lower end of the lower docking platform 19.

[0036] When the shower head 7 is damaged or clogged, first push the shower head 7 upward. At this time, the shower head 7 drives the fixed tube 6 to move upward together. The fixed tube 6 further drives the clamping lever 16 to move upward. During the upward movement of the clamping lever 16, its end will squeeze the outer surface of the upper docking platform 18. After being squeezed, the clamping lever 16 presses the extrusion spring 17 outward, causing the position of the clamping lever 16 to shift. After the clamping lever 16 moves to the upper end of the upper docking platform 18, pull the shower head 7 downward again. In this way, the upper docking platform 18 and the lower docking platform 19 will fit together. Then, continue to pull the clamping lever 16 downward through the outer surfaces of the upper docking platform 18 and the lower docking platform 19. Finally, the shower head 7 can be removed from the connection part.
