Description

Technical Field

[0001] The invention belongs to the technical field of vacuum pumps, and in particular relates to energy-saving vacuum pump equipment. Background Art

[0002] A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physicochemical methods to evacuate the container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain a vacuum in a closed space. According to the working principle of the vacuum pump, the vacuum pump can basically be divided into two types, namely gas capture pumps and gas transmission pumps, which are widely used in metallurgy, chemical industry, food, electronic coating and other industries.

[0003] When the vacuum pump is working to evacuate the equipment, the air inside the equipment often contains floating particles and dust. After working for a long time, a large amount of dust and floating objects will accumulate in the pump body. The parts in the pump body are covered with dust and floating objects, which will reduce the working efficiency of the pump body, thereby increasing the power output and increasing energy consumption.

[0004] To this end, relevant practitioners have designed a vacuum pump device such as that shown in CN220267969U, which adds a corresponding filter component in the pump to filter impurities, thereby reducing the energy consumption of the vacuum pump. However, the filtering capacity that the filter component can withstand is limited, and the corresponding operator sometimes forgets to replace it in time. Failure to replace it in time makes it easy for impurities to accumulate, which makes the pump require more energy to work. Summary of the invention

[0036] The embodiments of the present invention are intended to introduce and illustrate the structural composition of an energy-saving vacuum pump device and the coordination relationship between the various components. Unless otherwise specified, the dimensions, materials and manufacturing processes of the various components suitable for the energy-saving vacuum pump device in the embodiments of the present invention can be selected according to the specific circumstances and are not specifically limited or described herein.

[0037] Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. For those skilled in the art, the present invention can be fully understood without the description of these details.

[0038] See also Figure 1-Figure 5, this embodiment provides an energy-saving vacuum pump device, including a support plate 1, a housing 2, an air inlet pipe 21, an air outlet pipe 22, a motor 23, an air exhaust component 3, a transmission mechanism 4, a limiting component 5, a rotating component 6, a pushing component 7, a warning light 73 and a filtering component 8;

[0039] The housing 2 is arranged on the support plate 1, the air inlet pipe 21 and the air outlet pipe 22 are arranged on the housing 2 respectively, the motor 23 is arranged on the support plate 1, the output shaft of the motor 23 is passed through the housing 2, and the exhaust assembly 3 is coaxially fixed; it should be understood that the air inlet pipe 21 is arranged on the side away from the motor 23, the rotation of the motor 23 drives the exhaust assembly 3 to rotate, and then the air in the air inlet pipe 21 is extracted and discharged from the air outlet pipe 22, and the exhaust assembly 3 can be connected to the output shaft of the motor 23 through a coupling or the like. Preferably, the exhaust assembly 3 only drives the transmission mechanism 4 to rotate once per rotation.

[0040] The transmission mechanism 4 and the limiting component 5 are respectively rotatably arranged in the shell 2, the exhaust component 3 can intermittently drive the transmission mechanism 4 to rotate forward, and the limiting component 5 can limit the transmission mechanism 4 from reversing; specifically, each rotation of the exhaust component 3 can make the transmission mechanism 4 rotate forward by a certain angle, and the limiting component 5 can prevent the transmission mechanism 4 from falling back to the previous state due to reversal due to external force or gravity, so that each rotation of the exhaust component 3 can make the transmission mechanism 4 change its angular position and maintain the changed position for a period of time.

[0041] The rotating component 6 is rotatably installed on the top surface of the shell 2, the pushing component 7 is slidably installed on the shell 2, and the prompt light 73 is fixed on the shell 2. The rotation of the transmission component drives the pushing component 7 to slide toward the switch of the prompt light 73 through the rotating component 6. The switch of the prompt light 73 is a touch switch 731; specifically, the rotation of the transmission component drives the rotating component 6 to rotate, and the rotation of the rotating component 6 drives the pushing component 7 to move toward the switch of the prompt light 73. The switch of the prompt light 73 is electrically connected to the prompt light 73, and the prompt light 73 is powered by its own battery. After the pushing component 7 slides a certain distance, the switch of the prompt light 73 is squeezed, and the prompt light 73 lights up, prompting the replacement of the filter component 8; preferably, the pushing component 7 can be slidably placed in a straight line slide groove, and after squeezing the prompt light 73, it can be prepared for the next movement by picking it up and putting it back to the initial position.

[0042] The filter assembly 8 is detachably disposed in the housing 2. Specifically, the filter assembly 8 is located between the air intake pipe 21 and the exhaust assembly 3, and the pollutants sucked by the air intake pipe 21 are attached to the filter assembly 8. In order to reduce energy consumption, the transmission mechanism 4, the rotating assembly 6 and the pushing assembly 7 are preferably made of lightweight plastic, such as PP.

[0043] It is also worth mentioning that in order to avoid the influence of airflow caused by the exhaust assembly 3, a windshield plate 24 is provided in front of the transmission mechanism 4.

[0044] In the present application, the exhaust component 3 intermittently drives the transmission mechanism 4 to rotate, and the rotation of the transmission mechanism 4 drives the pushing component 7 to slide through the rotating component 6, that is, the exhaust component 3 intermittently drives the pushing component 7 to slide. When the exhaust component 3 rotates a sufficient number of circles, it is considered that the filter component 8 has also adsorbed enough pollutants. At this time, the pushing component 7 squeezes the switch of the prompt light 73 to prompt the relevant operator to replace the filter component 8, thereby reducing the occurrence of excessive attachment of pollutants to the filter component 8.

[0045] In other schemes, a connecting component 9 is also provided; the rotating component 6 is retractable, one end of the connecting component 9 is rotatably connected to the retractable end of the rotating component 6, and the other end is connected to the filtering component 8. The disassembly of the filtering component 8 can drive the rotating component 6 away from the transmission component, and the pushing component 7 is elastic.

[0046] It should be understood that the rotating assembly 6 drives the pushing assembly 7 to slide so that the elasticity of the pushing assembly 7 has the elastic force to drive the pushing assembly 7 to reset, and since the limiting assembly 5 limits the reverse rotation of the transmission mechanism 4 and thus limits the reverse rotation of the driven mechanism, the pushing assembly 7 can be fixed at the new position each time it moves to a new position. When the filter assembly 8 is removed, the filter assembly 8 drives the rotating assembly 6 away from the transmission mechanism 4 through the connecting assembly 9, that is, the rotating assembly 6 loses the restriction of the limiting assembly 5, and the pushing assembly 7 resets and drives the rotating assembly 6 to reverse under the action of its own elastic force. Due to the rotational connection between the rotating assembly 6 and the connecting assembly 9, the rotation of the rotating assembly 6 will not drive the connecting assembly 9 to rotate; when the filter assembly 8 is updated, the filter assembly 8 is reinstalled, and the connecting assembly 9 will drive the rotating assembly 6 to reconnect with the transmission mechanism 4. Through this structure, each time the filter assembly 8 is updated, the pushing assembly 7 is moved away from the prompt light 73, making the operation more convenient.

[0047] In other schemes, the exhaust assembly 3 includes an exhaust connecting rod 31, an incomplete gear 32 and a blade 33; the exhaust connecting rod 31 and the output shaft of the motor 23 are coaxially fixedly connected, the incomplete gear 32 is coaxially fixedly arranged on the exhaust connecting rod 31, and can drive the transmission mechanism 4 to rotate intermittently, and the blade 33 is arranged on the exhaust connecting rod 31 at one end away from the motor 23. Preferably, the incomplete gear 32 is set as a single-tooth gear, that is, it only drives the transmission mechanism 4 to rotate once per rotation. There are multiple groups of exhaust blades 33, and the air at the air inlet pipe 21 is extracted.

[0048] In other schemes, the transmission mechanism 4 includes a toggle assembly 41 and a driven assembly 42; the toggle assembly 41 and the driven assembly 42 are respectively rotatably connected to the housing 2, the exhaust assembly 3 can intermittently drive the toggle assembly 41 to rotate, the toggle assembly 41 can intermittently drive the driven assembly 42 to rotate, and the rotation of the driven assembly 42 can drive the rotating assembly 6 to rotate; the limiting assembly 5 can limit the reverse rotation of the toggle assembly 41. By intermittently driving the driven assembly 42 to rotate by the toggle assembly 41, the time required for the push assembly 7 to squeeze the switch of the prompt light 73 is further extended, and the possibility of the light turning on when there is too little adsorbed material is reduced.

[0049] In other embodiments, the toggle assembly 41 includes a toggle shaft 411, a toggle gear 412, a toggle ratchet 413, a rotating disk 414, an arc block 415 and a toggle rod 416; the toggle shaft 411 is rotatably connected to the housing 2, the toggle gear 412, the toggle ratchet 413 and the rotating disk 414 are coaxially fixed on the toggle shaft 411, the exhaust assembly 3 can intermittently drive the toggle gear 412 to rotate, and the limiting assembly 5 can limit the reverse rotation of the toggle ratchet 413; that is, the incomplete gear 32 can intermittently mesh with the toggle gear 412. The toggle rod 416 is eccentrically fixed on the rotating disk 414 and can intermittently drive the driven assembly 42 to rotate, and the arc block 415 is coaxially fixed on the rotating disk 414 and can limit the rotation of the driven assembly 42 when the toggle rod 416 is away from the driven assembly 42.

[0050] In other schemes, the driven assembly 42 includes a driven shaft 421, a first bevel gear 422 and a groove wheel 423; the driven shaft 421 is rotatably connected to the housing 2, the first bevel gear 422 and the groove wheel 423 are coaxially fixed on the driven shaft 421, the toggle rod 416 can intermittently drive the groove wheel 423 to rotate, and the first bevel gear 422 can drive the rotating assembly 6 to rotate. It should be understood that the toggle assembly 41 and the driven assembly 42 can be approximately regarded as a groove wheel 423 mechanism. Specifically, the toggle rod 416 drives the groove wheel 423 to rotate from bottom to top. Since the limiting assembly 5 limits the toggle rod 416 from reversing, the force applied by the fixed groove wheel 423 to the toggle rod 416, such as gravity or the reverse force brought by the pushing assembly 7, will make it difficult to reverse the toggle rod 416. The position of the toggle rod 416 is fixed, that is, the angle of the groove wheel 423 is fixed, and the arc block 415 is the same.

[0051] In other schemes, the rotating assembly 6 includes a telescopic rod 61, a second bevel gear 62 and a driven gear 63; the telescopic rod 61 is rotatably arranged in the housing 2, the fixed end of the telescopic rod 61 is coaxially fixed with a driven gear 63, the telescopic end of the telescopic rod 61 is coaxially fixed with the second bevel gear 62, and the transmission mechanism 4 can drive the second bevel gear 62 to rotate, that is, the first bevel gear 422 and the second bevel gear 62 in the transmission mechanism 4 are meshed. The driven gear 63 can drive the pushing assembly 7 to slide, and the connecting assembly 9 is rotatably connected to the telescopic end of the telescopic rod 61. Preferably, an annular groove is provided on the telescopic end of the telescopic rod 61, and the connecting assembly 9 is sleeved in the annular groove, and the upper and lower ends of the connecting assembly 9 can respectively abut against the upper and lower side surfaces of the annular groove, the fixed telescopic rod 61 rotates while the connecting assembly 9 does not rotate, and the connecting rod 91 is raised and lowered by abutting against the annular groove to drive the telescopic rod 61 to extend and retract. Specifically, the housing 2 is provided with a through hole through which the telescopic rod 61 passes, and the telescopic rod 61 is rotatably arranged therein. Preferably, a sealing gasket is further provided between the telescopic rod 61 and the through hole.

[0052] In other schemes, the pushing assembly 7 includes a rack 71 and a spring 72; the rack 71 is slidably connected to the housing 2 and connected to the housing 2 through the spring 72, and the rotating assembly 6 can drive the rack 71 to slide. Specifically, the rack 71 is meshed with the driven gear 63, and the rack 71 slides along a straight line. For the overall aesthetics, a corresponding box body can be added to the housing 2 to cover the pushing assembly 7 and the touch switch 731, and the top of the box body can be opened, so as to facilitate the corresponding adjustment of the angle of the telescopic rod 61, the position of the rack 71, etc. when necessary.

[0053] In other schemes, the filter assembly 8 includes a filter frame 81 and a filter plate 82; the filter frame 81 is inserted into the housing 2 in a liftable manner, the filter plate 82 is detachably arranged in the filter frame 81, and the connecting assembly 9 is connected to the filter frame 81. Specifically, the housing 2 is provided with an opening matching the filter frame 81, and the filter frame 81 can be lifted so that part of the filter frame 81 is leaked outside the housing 2, so as to replace a new filter plate 82, and the filter plate 82 is a combination of an activated carbon layer, a filter screen, etc. Preferably, a sealing strip is also provided on the filter frame 81 to close the opening with the housing 2, and the filter plate 82 is also preferably provided with a handle for easy lifting.

[0054] In other solutions, the connecting assembly 9 includes a connecting rod 91 and a connecting ring 92; one end of the connecting rod 91 is connected to the filter assembly 8, and the other end is fixed with a connecting ring 92, and the connecting ring 92 is rotatably connected to the rotating assembly 6. Specifically, one end of the connecting rod 91 is connected to the filter frame 81, and the connecting ring 92 is rotatably connected to the telescopic rod 61. Preferably, a sliding groove is provided on the filter frame 81, and the connecting rod 91 is slidably connected in the sliding groove of the filter frame 81, thereby further improving the lifting height of the filter frame 81.
