Description

Technical Field

[0001] This utility model relates to the field of vacuum pump technology, specifically to a vacuum pump that is easy to clean. Background Technology

[0002] A vacuum pump is generally a device that uses electricity to remove air from inside a container. The most common type of vacuum pump on the market is the water ring vacuum pump. It uses eccentric and high-speed rotating blades to form a water ring inside the casing. The cavities formed between the eccentric blades and the water ring are of different sizes. Through high-speed rotation, the space is continuously compressed and released to achieve the purpose of vacuuming. Vacuum pumps are mainly connected by a casing and a sealing plate. However, existing vacuum pumps install the sealing plate and the casing with bolts. In order to ensure the internal sealing of the vacuum pump during operation, multiple bolts are often required to tighten and fix it, which makes installation and disassembly cumbersome.

[0003] According to a vacuum pump for easy pipe cleaning (publication number: CN218934730U), the above application includes a base and a sealing plate. A drive motor is provided on one side of the upper surface of the base, a control box is provided on the top of the drive motor, a lifting ring is provided on the top of the drive motor, a support seat is provided on the upper surface of the base away from the drive motor, a pump housing is provided on the top of the support seat, and the output shaft end of the drive motor is mounted on the pump housing.

[0004] However, in actual use, the vacuum pumps mentioned above only simplify the number of bolts. It is still necessary to turn the knob to drive the threaded rod to achieve a stable installation of the housing. It still relies on repeated manual rotation, and the installation and disassembly process is still time-consuming. Especially when on-site maintenance or frequent disassembly and assembly are required, the operating efficiency is still not ideal. In view of this, we propose a vacuum pump that is easy to clean.

[0005] The purpose of this invention is to provide a vacuum pump that is easy to clean, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vacuum pump that is easy to clean, comprising a base, a pump body fixedly connected to the top of the base, a frame fixedly connected to the top end face of the base, a housing provided on the side wall of the pump body, and a connecting assembly provided on the side wall of the frame, the connecting assembly comprising:

[0007] A connecting rod is fixedly connected to the side wall of the housing, and a locking block is fixedly connected to the side wall of the housing;

[0008] A fixed frame is rotatably connected to a rotating shaft. A buckle is fixedly connected to the end face of the rotating shaft. A coil spring is sleeved on the side wall of the rotating shaft. An elastic element is fixedly connected to the side wall of the fixed frame.

[0009] Preferably, the side wall of the frame is provided with an insertion hole, which is inserted into a connecting rod. The insertion hole and the connecting rod guide the installation of the housing and the pump body. A sealing ring is fixedly connected to the side wall of the pump body.

[0010] Preferably, the fixing frame is fixedly connected to the side wall of the frame, and the buckle is movably connected to the buckle block to realize the installation of the shell.

[0011] Preferably, the end face of the elastic element abuts against the locking block, and a handle is fixedly connected to the outer wall of the buckle. By pulling the handle, the buckle can be opened, thereby fixing the shell.

[0012] Preferably, one end of the coil spring is fixedly connected to the outer wall of the rotating shaft, and the other end of the coil spring is fixedly connected to the outer wall of the fixing frame. The coil spring drives the buckle to reset through elastic deformation, thereby fixing the buckle.

[0013] Preferably, the frame is fixedly connected to the pump body, and a bracket is fixedly connected to the top end face of the base. The bracket abuts against the housing and supports the housing.

[0014] Preferably, the outer wall of the frame is hinged with a hinge frame, and the end face of the hinge frame is hinged with a hinge rod, the end of the hinge rod away from the hinge frame being hinged to the handle.

[0015] Compared with the prior art, this utility model provides a vacuum pump that is easy to clean and has the following features:

[0016] Beneficial effects:

[0017] 1. This easy-to-clean vacuum pump uses a set of connecting components, sockets, and connecting rods to precisely guide and position the housing and pump body, preventing assembly misalignment. The operator only needs to push the housing into place, and the locking block will automatically lock the latch, eliminating the need for complicated manual operation or repeated alignment, thus improving assembly efficiency and simplifying operation. The bracket abuts against the housing and provides support, reducing resonance, swaying, or vertical vibration of the housing caused by pump body rotation, eccentric disturbance, etc. during operation. The connecting rod and socket limit the lateral or vertical relative sway between the housing and the pump body, preventing misalignment or displacement caused by vibration. The coil spring provides continuous locking force, automatically compensating for micro-displacement and maintaining the fit and locking state of the mating surfaces.

[0018] 2. This easy-to-clean vacuum pump features a hinged frame. By rotating the hinged frame, two sets of handles on the side wall of the frame can be pulled simultaneously, further simplifying operation and avoiding the need to operate multiple parts back and forth. This results in high operating efficiency, simple control, improved disassembly efficiency, and consistent movement on both sides, preventing one side from jamming. It also ensures symmetrical force distribution and structural stability, thereby preventing the housing from tilting or deforming. Attached Figure Description

[0026] like Figures 1-6 As shown, this utility model provides a technical solution: a vacuum pump that is easy to clean, including a base 1, a pump body 2 fixedly connected to the top of the base 1, a frame 3 fixedly connected to the top end face of the base 1, a housing 4 provided on the side wall of the pump body 2, and a connecting component 6 provided on the side wall of the frame 3. The connecting component 6 includes a connecting rod 601, a locking block 602, a fixing frame 603, a rotating shaft 604, a coil spring 605, a buckle 606, an elastic element 607, and a socket 608.

[0027] In one embodiment of this utility model, the connecting rod 601 is fixedly connected to the side wall of the housing 4, and the side wall of the housing 4 is fixedly connected to the locking block 602. The side wall of the frame 3 is provided with an insertion hole 608, which is inserted into the connecting rod 601. The insertion hole 608 and the connecting rod 601 guide the installation of the housing 4 and the pump body 2. The side wall of the pump body 2 is fixedly connected to a sealing ring 10, which improves the sealing degree between the pump body 2 and the sealing ring 10.

[0028] The fixing frame 603 is fixedly connected to the side wall of the frame 3. The fixing frame 603 is rotatably connected to the rotating shaft 604. The end face of the rotating shaft 604 is fixedly connected to the buckle 606. The buckle 606 is movably connected to the locking block 602. The side wall of the rotating shaft 604 is fitted with a coil spring 605. The side wall of the fixing frame 603 is fixedly connected to an elastic element 607. The end face of the elastic element 607 abuts against the locking block 602. The outer wall of the buckle 606 is fixedly connected to a handle 7. By pulling the handle 7, the buckle 606 is opened, thereby fixing the shell 4.

[0029] One end of the coil spring 605 is fixedly connected to the outer wall of the rotating shaft 604, and the other end of the coil spring 605 is fixedly connected to the outer wall of the fixing frame 603. The coil spring 605 drives the buckle 606 to reset through elastic deformation, thereby fixing the buckle 602. The frame 3 is fixedly connected to the pump body 2. The top end face of the base 1 is fixedly connected to the bracket 5, which abuts against the housing 4 and supports the housing 4.

[0030] The insertion hole 608 and connecting rod 601 guide the installation of the housing 4 and pump body 2. The locking block 602 pushes the buckle 606 to rotate, and the buckle 606 moves away from the pump body 2. The coil spring 605 undergoes elastic deformation, and the locking block 602 inserts into the gap between the buckle 606 and the pump body 2. The coil spring 605 elastically drives the buckle 606 to rotate in the opposite direction and reset. Through the insertion hole 608 and connecting rod 601, the housing 4 and pump body 2 are precisely guided and positioned, avoiding misalignment during assembly. The operator only needs to push the housing 4... Once in place, the locking block 602 pushes the buckle 606 to automatically lock, eliminating the need for complex manual operation or repeated alignment, thus improving assembly efficiency and simplifying operation. The bracket 5 abuts against the housing 4 and provides support, reducing resonance, swaying, or vertical vibration of the housing 4 caused by pump body rotation, eccentric disturbance, etc. during operation. The connecting rod 601 and the insertion hole 608 restrict the lateral or vertical relative sway between the housing 4 and the pump body 2, preventing misalignment or displacement caused by vibration. The coil spring 605 provides continuous locking force, automatically compensating for micro-displacement and maintaining the fit and locking state of the mating surfaces.

[0031] When it is necessary to disassemble the housing 4, pull the handle 7 to unfold the buckle 606, and the elastic element 607 will push out the locking block 602, so that the housing 4 can be easily disassembled, realizing quick disassembly of the housing 4, reducing manual operation and improving disassembly efficiency.

[0032] In addition, the outer wall of the frame 3 is hinged with a hinge frame 8, and the end face of the hinge frame 8 is hinged with a hinge rod 9. The end of the hinge rod 9 away from the hinge frame 8 is hinged to the handle 7. By simply rotating the hinge frame 8, the two sets of handles 7 on the side wall of the frame 3 can be pulled at the same time, which further simplifies the operation, avoids operating multiple parts back and forth, has high operating efficiency and simple control, improves disassembly efficiency, keeps the movements on both sides consistent, avoids jamming on one side, ensures symmetrical force and structural stability, and thus prevents the shell 4 from tilting or deforming.

[0033] In this invention, during use, the insertion hole 608 and the connecting rod 601 guide the installation of the housing 4 and the pump body 2. The locking block 602 pushes the buckle 606 to rotate, and the buckle 606 moves away from the pump body 2. The coil spring 605 undergoes elastic deformation, and the locking block 602 inserts into the gap between the buckle 606 and the pump body 2. The coil spring 605 elastically drives the buckle 606 to rotate in the opposite direction to reset. Through the insertion hole 608 and the connecting rod 601, the housing 4 and the pump body 2 are precisely guided and positioned. The operator only needs to push the housing 4 into place, and the locking block 602 pushes the buckle 606 to automatically lock.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
