Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a quick connector kit with self-cleaning function. Background Technology

[0002] The flushing device has a multi-section pipe connection structure. During operation, the water pressure in the pipes is relatively high. In order to prevent the pipe connections from loosening, falling off, or leaking, a reliable connection structure must be installed between the pipes.

[0003] Pipe connection refers to the process of connecting prefabricated pipe sections into a complete system according to the design drawings. During construction, different connection methods should be selected based on the material of the pipes used. Common steel pipes can be connected using methods such as threaded connections, flange connections, welding connections, socket connections, and pipe adhesive connections.

[0004] Common pipe connection methods, such as threaded connections and flange connections, cannot achieve a quick and convenient connection effect and are not convenient for flexible disassembly and assembly of pipes.

[0005] Secondly, the quick-connect head lacks a self-cleaning function, which can lead to the accumulation of dirt inside after prolonged use, affecting the subsequent rinsing effect and increasing the frequency of head replacement. This issue urgently needs to be addressed. Utility Model Content

[0006] The purpose of this invention is to provide a quick connector kit with a self-cleaning function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick connector kit with self-cleaning function, comprising a splicing assembly block, a fixing block, a built-in limiting block, and a flushing head. Limiting cavities are connected to both sides of the splicing assembly block. A built-in limiting block is connected to each limiting cavity via a return spring. A fixing block and a manual pressing rod are connected to the side of the built-in limiting block away from the return spring. The manual pressing rod extends to the outside of the side of the splicing assembly block. A matching mounting connector is provided at the top of the splicing assembly block, and a flushing head is connected to the bottom of the splicing assembly block. Both sides of the assembly joint are connected to fixing slots that match the fixing blocks. The manual pressing rod, return spring, built-in limit block, and limit cavity are designed and used in conjunction to manually control the insertion state of the fixing blocks and fixing slots. When the manual pressing rod is pressed to separate the fixing blocks from the fixing slots, the installation joint, which has lost its limit, can be disassembled from the assembly block. This allows for quick control of the assembly and disassembly of the assembly block and the installation joint. Compared with common pipe connection methods such as threaded connections and flange connections, this method achieves a fast and convenient connection and enables flexible assembly and disassembly of the assembly block.

[0008] Preferably, a sealing ring is provided between the splicing assembly block and the installation splice joint. The sealing ring can improve the sealing performance at the splicing installation point between the splicing assembly block and the installation splice joint, as well as the smooth flow of water through the medium channels inside the splicing assembly block and the installation splice joint.

[0009] Preferably, the splicing assembly block, the mounting splice joint, and the flushing head have an internal medium flow channel running through them. The bottom of the flushing head is connected to a medium outlet. The internal medium flow channel allows water to pass smoothly through the mounting splice joint, the splicing assembly block, and the flushing head. When water comes into contact with the movable ring block through the outlet, the impact force pushes the movable ring block forward, causing the cleaning ring bristles to move and perform a self-cleaning action on the inner wall of the splicing assembly block and the flushing head, reducing the adhesion and accumulation of dirt.

[0010] Preferably, the upper end of the flushing head is connected to a limiting edge, and the limiting edge is internally connected to a through-hole.

[0011] Preferably, both sides of the bottom of the limiting spacer are hinged with return springs, and the lower ends of the two return springs are simultaneously hinged to the movable ring block. The return springs can help the cleaning ring bristles return to their original position with the movable ring block after use, making it convenient for repeated cleaning next time.

[0012] Preferably, the outer edge surface of the movable ring block is provided with cleaning ring bristles.

[0013] Preferably, the movable ring block has an internal connection with a second through port.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This type of quick-connect fitting kit with self-cleaning function can manually control the insertion state of the fixed card block and the fixed card slot by setting and using the manual pressing rod, return spring, built-in limit block and limit cavity. When the manual pressing rod is pressed to separate the fixed card block from the fixed card slot, the installation splice can be separated from the splice assembly block after losing the limit. This can quickly control the disassembly and assembly of the splice assembly block and the installation splice. Compared with common pipe connection methods, such as threaded connection and flange connection, it can achieve a fast and convenient connection effect and realize the flexible disassembly and assembly of the splice assembly block.

[0016] (2) This quick connector kit with self-cleaning function allows water to pass smoothly through the installation splice, splice assembly block and flushing head by setting the internal medium flow channel. When water comes into contact with the movable ring block through the inlet, the impact force will push the movable ring block forward, so that the cleaning ring bristles can move to perform self-cleaning on the splice assembly block and the inner wall of the flushing head, reducing the adhesion and accumulation of dirt. The return spring can help the cleaning ring bristles to return to their original position with the movable ring block after use, making it convenient for repeated cleaning next time.

[0017] (3) This quick-connect fitting kit with self-cleaning function can improve the sealing performance of the splicing assembly block and the installation splicing joint at the splicing installation point, as well as the smooth flow of water in the medium flow channel inside the splicing assembly block and the installation splicing joint by setting the sealing clamp ring.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-4The present invention provides an embodiment of a quick connector kit with self-cleaning function, comprising a splicing assembly block 1, a fixing block 7, an internal limiting block 13 and a flushing head 18. Both sides of the splicing assembly block 1 are connected to limiting cavities 16, which are used for the movement of the internal limiting block 13.

[0025] The limiting cavity 16 is connected to the built-in limiting block 13 by the return spring 9. The side of the built-in limiting block 13 away from the return spring 9 is connected to the fixing block 7 and the manual pressing rod 8 respectively. The expansion of the return spring 9 keeps the fixing block 7 and the fixing slot 6 in a tight fit. Pressing the manual pressing rod 8 can control the fixing block 7 to separate from the fixing slot 6. The engagement of the fixing block 7 and the fixing slot 6 realizes the fastening of the splicing assembly block 1 and the installation splicing joint 11.

[0026] The manual pressing rod 8 extends to the side of the splicing assembly block 1. The top of the splicing assembly block 1 is provided with a matching mounting splice 11. The bottom of the splicing assembly block 1 is connected to a flushing head 18. Both sides of the mounting splice 11 are connected to a fixing slot 6 that matches the fixing block 7.

[0027] A sealing ring 2 is provided between the splicing assembly block 1 and the installation splicing joint 11. The sealing ring 2 can improve the sealing performance of the connection between the splicing assembly block 1 and the installation splicing joint 11. The sealing ring 2 is connected to the upper surface of the splicing assembly block 1.

[0028] The splicing assembly block 1, the mounting splice 11 and the flushing head 18 are all connected by an internal medium flow channel 4. The bottom of the flushing head 18 is connected to a medium outlet 10, and the internal medium flow channel 4 is connected to the medium outlet 10.

[0029] The upper end of the flushing head 18 is connected to a limiting edge 3, and the inside of the limiting edge 3 is connected to a through port 5, which communicates with the inner medium flow channel 4. The through port 5 does not obstruct the passage of the medium.

[0030] Both sides of the bottom of the limiting partition 3 are hinged with return springs 12. The lower ends of the two return springs 12 are simultaneously hinged to the movable ring block 15. The return springs 12 can assist the movable ring block 15 in resetting. The return springs 12 are hinged to the limiting partition 3 and the movable ring block 15 to adapt to the movement of the movable ring block 15 and improve the service life of the return springs 12 and the movable ring block 15.

[0031] The outer edge surface of the movable ring block 15 is provided with a cleaning ring bristle 14, which is used to clean the inner wall of the splicing assembly block 1 and the flushing head 18.

[0032] The movable ring block 15 is internally connected to a second through-hole 17, which is connected to the internal medium flow channel 4. The setting of the second through-hole 17 does not hinder the passage of the medium, and the impact force of the medium will push the movable ring block 15 to move inside the internal medium flow channel 4.

[0033] In this embodiment, the manual pressing rod 8, the return spring 9, the built-in limiting block 13, and the limiting cavity 16 are configured and used in combination to manually control the insertion state of the fixing block 7 and the fixing slot 6. When the manual pressing rod 8 is pressed to separate the fixing block 7 from the fixing slot 6, the installation splice 11, which loses its limiting position, can be separated from the splicing assembly block 1, thus enabling quick control of the splicing assembly block 1 and the installation splice 11. The internal medium flow channel 4 allows water to pass smoothly through the installation splice 11, the splicing assembly block 1, and the flushing head 18. When water comes into contact with the movable ring block 15 through the opening 5, the impact force pushes the movable ring block 15 forward, causing the cleaning ring bristles 14 to move accordingly, which can perform self-cleaning on the inner wall of the splicing assembly block 1 and the flushing head 18.
