Description

Technical Field

[0001] This application relates to the field of peristaltic pump technology, specifically a novel peristaltic pump protective cover for a dishwasher dispenser. Background Technology

[0002] A peristaltic pump is an instrument or device consisting of three parts: a driver, a pump head, and a tubing. Its main competitive advantages lie in the isolation of the fluid within the pump tubing, quick tubing replacement, reversible flow, dry operation, and low maintenance costs. A peristaltic pump works like squeezing a fluid-filled tube with your fingers; as you slide your fingers forward, the fluid moves forward. A peristaltic pump operates on the same principle, but with rollers instead of fingers. Fluid is pumped by alternately squeezing and releasing the pump's elastic delivery tubing. Just like squeezing a tube with two fingers, as the fingers move, a negative pressure is created inside the tube, causing the liquid to flow.

[0003] Peristaltic pumps typically consist of a housing and a peristaltic component located inside the housing. After the peristaltic component is assembled, a cover plate is usually installed on the housing to protect it. Existing cover plates are usually fastened with multiple screws or are integrated with the housing, making disassembly and assembly inconvenient. Since the peristaltic component is a consumable part, it usually requires maintenance. Such cover plates that are difficult to disassemble and install are inconvenient for maintaining peristaltic pumps and have certain shortcomings.

[0004] Therefore, this application provides a novel peristaltic pump protective cover for a dishwasher dispenser to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a novel peristaltic pump protective cover for a dishwasher dispenser, aiming to solve the problems mentioned in the background art, such as the fact that existing covers are usually fastened with multiple screws or are integrated with the housing, making disassembly and assembly inconvenient, while peristaltic components are vulnerable parts that usually require maintenance. These difficult-to-disassemble covers are inconvenient for maintaining the peristaltic pump, and have certain shortcomings.

[0006] To achieve the above objectives, this application provides the following technical solution: a novel peristaltic pump protective cover for a dishwasher dispenser, comprising a cover rotatably mounted on the peristaltic pump body for protecting the peristaltic components within the peristaltic pump body: A column is fixedly mounted on the peristaltic pump body. A connecting block, which is hinged to the column and fixedly connected to a cover plate, is connected to the end of the cover plate away from the connecting block. A stud extends through the cover plate and into the peristaltic pump body. An internally threaded tube that matches the stud is fixedly mounted on the peristaltic pump body. Thus, when the peristaltic pump body is closed, the cover plate is rotated along the column. The cover plate rotates via the connecting block, and when it reaches the surface of the peristaltic pump body, the stud aligns perfectly with the internally threaded tube. Then, the stud is rotated to connect with the internally threaded tube, thereby fixing the cover plate to the surface of the peristaltic pump body. Subsequent disassembly and assembly are convenient and quick, facilitating inspection and maintenance.

[0007] Preferably, for installing the internally threaded tube, the peristaltic pump body has a socket adapted to the internally threaded tube, and the internally threaded tube is inserted into the socket. This secures the tube to the peristaltic pump body, facilitating production.

[0008] Preferably, for fixation, a threaded connector with a diameter larger than the stud is fixedly installed at one end of the stud extending towards the peristaltic pump body, and the threaded connector is screwed into the internally threaded tube. This completes the fixation of the cover plate and the peristaltic pump body quickly and easily.

[0009] Preferably, to reduce noise, a sealing cotton is fixedly installed on the side of the cover plate facing the inside of the peristaltic pump body. This reduces noise when the peristaltic pump body is working, resulting in better performance.

[0010] Preferably, to assist in opening the cover, the protective cover further includes a pushing mechanism. The pushing mechanism includes a sleeve fixedly installed inside the peristaltic pump body. A spring rod extending towards the cover but not in contact with it is inserted into the sleeve. A spring that abuts against the spring rod is fixedly installed inside the sleeve. This provides assistance to the cover, making it easier to open.

[0011] Preferably, to prevent the spring rod from detaching, an anti-detachment groove is provided inside the sleeve, and an anti-detachment block adapted to the anti-detachment groove is fixedly installed on one end of the spring rod located inside the sleeve. The anti-detachment block is slidably installed in the anti-detachment groove. When the spring is ejected, it will not detach from the sleeve, ensuring safety and stability.

[0012] The protective cover is rotated along the column. The cover rotates through the connecting block and when it reaches the surface of the peristaltic pump body, the stud is aligned with the internal threaded tube on the peristaltic pump body. Then, the stud is rotated to connect the stud with the internal threaded tube, thereby fixing the cover to the surface of the peristaltic pump body. Subsequent disassembly and assembly are convenient and quick, facilitating inspection and maintenance.

[0013] When the protective cover is closed, the inner wall of the cover presses against a spring rod, which in turn compresses the spring, causing the spring to contract. When the peristaltic pump needs to be inspected after prolonged use, the spring pushes the spring rod to assist in opening the cover, making it easier to open. Attached Figure Description

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Example 1 This embodiment provides a novel peristaltic pump protective cover for a dishwasher dispenser, such as... Figure 1-3 As shown, the protective cover includes a cover 2 rotatably mounted on the peristaltic pump body 1 for protecting the peristaltic components inside the peristaltic pump body 1: A column 21 is fixedly installed on the peristaltic pump body 1. A connecting block 22 is hinged to the column 21 and fixedly connected to the cover plate 2. A stud 23 is inserted into the end of the cover plate 2 away from the connecting block 22 and extends into the peristaltic pump body 1. An internally threaded tube 24 that is compatible with the stud 23 is fixedly installed on the peristaltic pump body 1.

[0018] In use, rotate the cover plate 2 along the column 21. The cover plate 2 rotates through the connecting block 22. When it rotates to the surface of the peristaltic pump body 1, the stud 23 is just connected to the internal threaded tube 24 on the peristaltic pump body 1. Then rotate the stud 23 to connect the stud 23 to the internal threaded tube 24, thereby fixing the cover plate 2 to the surface of the peristaltic pump body 1. Subsequent disassembly and assembly are convenient and quick, and easy to inspect and maintain.

[0019] Specifically, the peristaltic pump body 1 has an insertion hole 25 that matches the internal threaded tube 24, and the internal threaded tube 24 is inserted into the insertion hole 25. In use, glue is applied to the outside of the internal threaded tube 24, and it is inserted into the insertion hole 25 to fix it to the peristaltic pump body 1, which facilitates production.

[0020] More specifically, a threaded connector 26 with a diameter larger than that of the stud 23 is fixedly installed at one end extending into the peristaltic pump body 1. The threaded connector 26 is screwed into the internally threaded tube 24. In use, since the diameter of the threaded connector 26 is larger than that of the stud 23, the stud 23 cannot detach from the cover plate 2. Rotating the stud 23 drives the threaded connector 26 to connect with the internally threaded tube 24, thus completing the fixation of the cover plate 2 and the peristaltic pump body 1, which is convenient and quick.

[0021] Furthermore, a sealing cotton 27 is fixedly installed on the side of the cover plate 2 facing the inside of the peristaltic pump body 1. In use, when the cover plate 2 is closed, the cover plate 2 presses down, pressing against the hose interface installed inside the peristaltic pump body 1, thereby reducing noise when the peristaltic pump body 1 is working and improving its practical effect.

[0022] Example 2 Unlike Embodiment 1, the cover plate 2 may become stuck after prolonged use, making it inconvenient to open. Therefore, this protective cover plate also includes a pushing mechanism 3. The pushing mechanism 3 includes a sleeve 31 fixedly installed inside the peristaltic pump body 1. A spring rod 32, extending towards but not in contact with the cover plate 2, is inserted into the sleeve 31. A spring 35, which abuts against the spring rod 32, is fixedly installed inside the sleeve 31. In use, when the cover plate 2 is closed, the inner wall of the cover plate 2 presses against the spring rod 32, causing the spring rod 32 to compress the spring 35, which in turn contracts. When the peristaltic pump needs maintenance after prolonged use, opening the cover plate 2 allows the spring 35 to push the spring rod 32, providing assistance and making it easier to open the cover plate 2.

[0023] Specifically, the sleeve 31 has an anti-detachment groove 34, and an anti-detachment block 33 adapted to the anti-detachment groove 34 is fixedly installed on one end of the spring rod 32 inside the sleeve 31. The anti-detachment block 33 is slidably installed in the anti-detachment groove 34. In use, the spring rod 32 slides up and down in the anti-detachment groove 34 inside the sleeve 31 through the anti-detachment block 33. Due to the obstruction of the anti-detachment groove 34, the spring rod 32 will not detach from the sleeve 31 when it is ejected by the spring 35, which is safe and stable.

[0024] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
