Description

Technical Field

[0001] This utility model relates to the field of direct drinking water equipment technology, specifically a direct drinking water system with self-cleaning function. Background Technology

[0002] With the improvement of people's living standards, direct drinking water systems have been widely used in homes, schools, offices and other places.

[0003] After long-term use, the inner walls of direct drinking water system pipes are prone to accumulating scale, bacteria, microorganisms, and other impurities, which not only affect water quality but may also harm human health. Currently, cleaning the pipes of most direct drinking water systems on the market is quite troublesome, usually requiring disassembly and cleaning. This is not only cumbersome and time-consuming, but frequent disassembly can also damage the pipes and affect the service life of the direct drinking water system. Therefore, this utility model proposes a direct drinking water system with a self-cleaning function to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a direct drinking water system with a self-cleaning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a direct drinking water system with self-cleaning function, comprising a first pipe, a second pipe, and a cleaning component;

[0006] The first pipe is a through structure, with a connection port at one end and a water supply pipe at the other end; the second pipe is connected to the first pipe.

[0007] The cleaning assembly is disposed inside the second pipe and includes a cleaning roller, a first abutment plate, a second abutment plate, a mounting plate, and a telescopic cylinder;

[0008] The left and right ends of the cleaning roller are integrally formed with the first abutment plate and the second abutment plate, respectively. The right port of the second abutment plate is provided with a mounting plate. A telescopic cylinder is installed in the mounting plate. One end of the telescopic cylinder passes through the mounting plate and is connected to the second abutment plate.

[0009] The second pipe is also equipped with a water inlet pipe, and the water inlet pipe is located on the right side of the first abutment plate.

[0010] Preferably, the brush structure on the surface of the cleaning roller has a flexible design that can tightly fill the space inside the first pipe to enhance the cleaning effect on the inside of the first pipe.

[0011] Preferably, the first and second abutment plates at both ends of the cleaning roller are designed to be the same size, and the outer diameters of the two abutment plates are respectively adapted to the inner diameters of the first and second pipes, forming a sealing structure that fits against the inner wall of the pipe.

[0012] Preferably, the outer wall of the right port of the second pipe is provided with external threads, and the mounting plate is screwed onto the inner wall of the second pipe by means of thread engagement.

[0013] Preferably, a sealing ring is embedded in the annular cavity of the mounting plate to enhance the sealing of the connection.

[0014] Preferably, the output end of the telescopic cylinder is provided with a connecting block, which is connected to the positioning cavity of the second abutment plate on the right side of the cleaning roller by bolts.

[0015] Preferably, the first pipe and the second pipe are mounted on the ground via supports.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) By installing a retractable cleaning component in the second pipe, cleaning can be achieved without disassembling the pipe. When cleaning is required, the telescopic cylinder drives the cleaning roller into the first pipe, and the cleaning agent is introduced into the water inlet pipe to reciprocate, effectively removing scale, bacteria and other impurities from the inner wall of the pipe. This self-cleaning method greatly simplifies the cleaning process, reduces manpower and time costs, and avoids pipe damage caused by disassembly, significantly extending the service life of the direct drinking water system.

[0018] (2) The reliability of the system is improved by multiple sealing designs. The first and second abutment plates at both ends of the cleaning roller are adapted to the inner diameter of the pipe to form a close-fitting sealing structure. The sealing ring embedded in the annular cavity of the installation plate further enhances the sealing of the installation part. The second pipe and the installation plate are screwed together to ensure a tight connection. These designs effectively prevent liquid leakage, avoid equipment damage and water pollution caused by water leakage, and ensure the safe and stable operation of the direct drinking water system.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 to 4 This utility model provides a technical solution: a direct drinking water system with self-cleaning function, including a first pipe 1, a second pipe 4, and a cleaning component 5. The first pipe 1 is a through structure, with a connection port 2 at one end and a water supply pipe 3 at the other end. The second pipe 4 is connected to the first pipe 1. The cleaning component 5 is disposed in the second pipe 4 and includes a cleaning roller 51, a first abutment plate 52, a second abutment plate 53, a mounting plate 55, and a telescopic cylinder 54. The left and right ends of the cleaning roller 51 are integrally formed with the first abutment plate 52 and the second abutment plate 53, respectively. The right end of the second abutment plate 53 is provided with a mounting plate 55, and a telescopic cylinder 54 is assembled in the mounting plate 55. One end of the telescopic cylinder 54 passes through the mounting plate 55 and is connected to the second abutment plate 53. The second pipe 4 is also provided with a water inlet pipe 6, which is located to the right of the first abutment plate 52.

[0026] By installing a retractable cleaning component 5 inside the second pipe 4, cleaning can be achieved without disassembling the pipe. When cleaning is required, the telescopic cylinder 54 drives the cleaning roller 51 into the first pipe 1, and in conjunction with the water inlet pipe 6, the cleaning agent is introduced to reciprocate, effectively removing scale, bacteria and other impurities from the inner wall of the pipe. This self-cleaning method greatly simplifies the cleaning process, reduces labor and time costs, and avoids pipe damage caused by disassembly, significantly extending the service life of the direct drinking water system.

[0027] Please see Figure 3 as well as Figure 4 It is understood that the bristle structure on the surface of the cleaning roller 51 has a flexible bristle design that can tightly fill the space of the inner wall of the first pipe 1 to enhance the cleaning effect on the inner wall of the first pipe 1.

[0028] Please see Figures 1 to 4The first abutment 52 and the second abutment 53 at both ends of the cleaning roller 51 are designed to be the same size, and the outer diameter of the two abutments is adapted to the inner diameter of the first pipe 1 and the second pipe 4 respectively, forming a sealing structure that fits against the inner wall of the pipe.

[0029] Please see Figures 1 to 4 The outer wall of the right port of the second pipe 4 is provided with an external thread 41. The mounting plate 55 is screwed onto the inner wall of the second pipe 4 by means of thread engagement. The mounting plate 55 is installed on the inner wall of the second pipe 4 by means of a spiral. When it is necessary to clean the internal cleaning roller 51, the mounting plate 55, the telescopic cylinder 54, and the cleaning roller 51 connected to the output end of the telescopic cylinder 54 can be pulled out by means of a spiral, which facilitates the subsequent cleaning work of the cleaning roller 51.

[0030] Please see Figures 1 to 4 A sealing ring 56 is embedded in the annular cavity of the mounting plate 55 to enhance the sealing of the connection.

[0031] Please see Figures 1 to 4 The output end of the telescopic cylinder 54 is provided with a connecting block 541. The connecting block 541 is connected to the positioning cavity of the second abutment plate 53 on the right side of the cleaning roller 51 by bolts. By using bolt connection, when the equipment needs to be repaired or the telescopic cylinder 54 or the cleaning roller 51 needs to be replaced, the two can be separated simply by unscrewing the bolts. The operation is simple and convenient. Compared with other fixed connection methods, this detachable connection structure greatly reduces the difficulty of maintenance.

[0032] Please see Figures 1 to 4 The first pipe 1 and the second pipe 4 are erected above the ground by a support 7.

[0033] In use, water enters from the connection port 2 of the first pipe 1. Due to the obstruction of the first abutment plate 52, the water cannot pass directly through the second pipe 4, but flows along the inner wall of the first pipe 1 and finally flows out from the water supply pipe 3, achieving a normal supply of drinking water. The first abutment plate 52 and the second abutment plate 53 are respectively attached to the inner wall of the second pipe 4 to maintain the sealing of the pipe system and ensure a stable water output. When it is necessary to clean the first pipe 1, the telescopic cylinder 54 is activated. The telescopic cylinder 54 pushes the second abutment plate 53 through the connecting block 541 at the output end, causing the cleaning roller 51 to move to the left. Since the first abutment plate 52 and the second abutment plate 53 at both ends of the cleaning roller 51 are adapted to the inner diameter of the first pipe 1 and the second pipe 4, the cleaning roller 51 can smoothly enter the first pipe 1 until the first abutment plate 52 is attached to the inner wall of the first pipe 1, and then the water flows out through the second abutment plate 53. The cleaning agent is introduced into the water inlet pipe 6 on the second pipe 4. The flexible bristle structure tightly fills the inner wall space of the first pipe 1, providing conditions for the cleaning agent to fully contact the inner wall of the pipe, ensuring that the cleaning agent can evenly cover the dirt and impurities on the inner wall of the first pipe 1. The telescopic cylinder 54 works continuously, driving the cleaning roller 51 to reciprocate in the first pipe 1. During the movement, the bristles rub against the inner wall of the first pipe 1, and with the chemical action of the cleaning agent, effectively remove scale, bacteria, microorganisms and other impurities attached to the inner wall of the pipe. After cleaning, the telescopic cylinder 54 drives the cleaning roller 51 to retract into the second pipe 4, and the first abutment plate 52 blocks the connection between the first pipe 1 and the second pipe 4 again. At this time, the wastewater formed by the cleaned dirt and the remaining cleaning agent is discharged from the water supply pipe 3 along the first pipe 1, completing the entire self-cleaning process.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
