Description

Technical Field

[0001] The utility model relates to the technical field of vacuum generators, in particular to a multifunctional vacuum generator. Background Art

[0002] A vacuum generator is a new type of efficient, clean, economical, and small vacuum component that uses a positive pressure gas source to generate negative pressure. This makes it very easy and convenient to obtain negative pressure in places where compressed air is available, or where positive and negative pressures are required at the same time in a pneumatic system. Vacuum generators are widely used in industrial automation in the fields of machinery, electronics, packaging, printing, plastics, and robotics.

[0003] A Chinese patent (publication number CN218760307U) discloses a multifunctional vacuum generator including an adjustment mechanism, a front cover, a rear cover, and a first cavity, a second cavity, and a third cavity in a hollow shape; the front cover, the first cavity, the second cavity, the third cavity, and the rear cover are detachably connected in sequence, and the first cavity, the second cavity, and the third cavity are respectively formed with a first channel, a second channel, and a third channel that can be interconnected; the rear cover or the third cavity is provided with an air outlet connected to the third channel; the second cavity is provided with a vacuum output hole connected to the second channel. The purpose of adopting this technical solution is to provide a multifunctional vacuum generator, and the technical solution provided by this application solves the problem that the existing vacuum generator cannot adjust the intake pressure, cannot change the intake, outlet, and vacuuming directions of the vacuum generator, resulting in excessive energy consumption and inconvenience in use of the vacuum generator.

[0004] However, during the air intake process of the above-mentioned vacuum generator, dust particles will be sucked into the interior of the vacuum generator, and a large amount of dust may clog the filter and gas inlet and outlet of the vacuum generator, causing it to fail to work normally. Long-term influence of dust may also cause damage to the electrical components of the vacuum generator. These adverse effects may cause the working efficiency of the vacuum generator to decrease, thereby increasing its energy consumption. Although some vacuum generators use filters to filter dust, the filters will be clogged with granular dust after long-term use, resulting in a decrease in the circulating airflow, thereby reducing the working efficiency of the vacuum generator. Utility Model Content

[0005] In view of the above problems, a multifunctional vacuum generator is provided. The filter can effectively filter dust and particles in the air, thereby preventing these impurities from clogging the filter and the gas inlet and outlet of the vacuum generator. When the filter holes on the filter are clogged with large particles, pull the pull rod to drive the rotating positioning rod to disengage from the positioning hole on the side wall of the mounting frame. Then, rotate the rotating positioning rod one hundred and eighty degrees to place another unused filter in front of the air inlet end of the vacuum generator to ensure that the filtering effect is not affected. At the same time, the used filter will come into contact with the soft brush during rotation. Through the friction of the soft brush, the dust particles on the filter can be effectively removed, preparing for subsequent use. In order to further improve the cleanliness of the filter, we recommend rotating the filter a few more times when rotating the filter to ensure that the unused filter will not adhere to dust in the air, thereby maintaining its optimal filtering effect.

[0006] To solve the problems of the prior art, the utility model provides a multifunctional vacuum generator, including a vacuum generator body, wherein the vacuum generator body is arranged inside an installation frame, a rotating drum is arranged on an outer wall of one side of the installation frame through a rotating shaft, and a mounting block is arranged on one side of the rotating drum, a soft brush is arranged on the inner wall of the mounting block, a connecting block is arranged on the outside of the rotating drum, and filters are arranged at both ends of the connecting block, a sliding groove for a rotating positioning rod to move is opened inside the rotating drum, a pull rod is arranged on the outer wall of the rotating positioning rod, and one end of the pull rod extends to the outside of the rotating drum, a first spring is sleeved on the outside of the pull rod, one end of the first spring is connected to the outer wall of the rotating positioning rod, and the other end of the first spring is connected to the inner wall of the rotating drum.

[0007] Preferably, the outer wall of the installation frame is provided with a positioning hole cooperating with the rotating positioning rod.

[0008] Preferably, the mounting frame is movably arranged inside the noise reduction frame, a plurality of damping rods are arranged inside the noise reduction frame, the movable ends of the damping rods are connected to the bottom of the mounting frame, a shock-absorbing spring is sleeved on the outside of the damping rods, one end of the shock-absorbing spring is connected to the inside of the noise reduction frame, and the other end of the shock-absorbing spring is connected to the bottom of the mounting frame.

[0010] Preferably, inner walls on both sides of the noise reduction frame are provided with grooves adapted to the convex rods.

[0011] Preferably, a sound absorbing panel is provided on the inner wall of the installation frame.

[0012] Preferably, through holes for mounting the air inlet and the air outlet of the vacuum generator body are provided on both sides of the mounting frame.

[0013] Preferably, the size of the through holes at the air inlet and outlet is consistent with the size of the filter screen.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The filter can effectively filter dust and particles in the air, thereby preventing these impurities from clogging the filter and its gas inlet and outlet of the vacuum generator. When the filter holes on the filter are blocked by large particles, pull the pull rod to drive the rotating positioning rod to disengage the positioning hole on the side wall of the mounting frame. Then, rotate the rotating positioning rod 180 degrees to place another unused filter in front of the air inlet end of the vacuum generator to ensure that the filtering effect is not affected. At the same time, the used filter will come into contact with the soft brush during rotation. Through the friction of the soft brush, the dust particles on the filter can be effectively removed, preparing for subsequent use. In order to further improve the cleanliness of the filter, rotate the filter a few more times to ensure that the unused filter will not adhere to the dust in the air, thereby maintaining its best filtering effect.

[0016] 2. Through the coordinated work of the damping rod and the shock-absorbing spring, the vibration generated by the vacuum generator body during operation can be significantly reduced, thereby effectively reducing its noise level during operation. In addition, the ingenious cooperation of the convex rod, the second spring and the groove can further significantly reduce the noise generated by the vacuum generator body, thereby achieving a quieter working environment.

DETAILED DESCRIPTION

[0023] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figures 1 to 5 As shown, the utility model provides:

[0025] A multifunctional vacuum generator includes a vacuum generator body 1, which is arranged inside a mounting frame 2. A rotating drum 8 is arranged on an outer wall of one side of the mounting frame 2 through a rotating shaft, and a mounting block 4 is arranged on one side of the rotating drum 8. A soft brush 6 is arranged on the inner wall of the mounting block 4. A connecting block 11 is arranged outside the rotating drum 8. Filters 3 are arranged at both ends of the connecting block 11. A sliding groove for a rotating positioning rod 7 to move is opened inside the rotating drum 8. A pull rod 10 is arranged on the outer wall of the rotating positioning rod 7, and one end of the pull rod 10 extends to the outside of the rotating drum 8. A first spring 9 is sleeved on the outside of the pull rod 10, and one end of the first spring 9 is connected to the outer wall of the rotating positioning rod 7, and the other end of the first spring 9 is connected to the inner wall of the rotating drum 8.

[0026] The filter 3 can effectively filter dust and particles in the air, thereby preventing these impurities from clogging the filter and the gas inlet and outlet of the vacuum generator. When the filter holes on the filter 3 are blocked by large particles, pull the pull rod 10 to drive the rotating positioning rod 7 to disengage from the positioning hole on the side wall of the mounting frame 2. Then, rotate the rotating positioning rod 7 one hundred and eighty degrees to place another unused filter 3 in front of the air inlet end of the vacuum generator to ensure that the filtering effect is not affected. At the same time, the used filter 3 will come into contact with the soft brush 6 during the rotation process. Through the friction of the soft brush 6, the dust particles on the filter 3 can be effectively removed, preparing for subsequent use. In order to further improve the cleanliness of the filter 3, we recommend rotating the filter 3 a few more times when rotating it to ensure that the unused filter 3 will not adhere to the dust in the air, thereby maintaining its optimal filtering effect.

[0027] Figure 2 As shown, the outer wall of the installation frame 2 is provided with a positioning hole that cooperates with the rotating positioning rod 7.

[0028] The positioning hole cooperates with the rotating positioning rod 7 to prevent the rotating positioning rod 7 from shaking easily, thereby ensuring that the vacuum generator body 1 can filter external dust when working.

[0029] like Figure 4 and Figure 5 As shown, the mounting frame 2 is movably arranged inside the noise reduction frame 5, and a plurality of damping rods 12 are arranged inside the noise reduction frame 5. The movable ends of the damping rods 12 are connected to the bottom of the mounting frame 2, and the outer sleeve of the damping rods 12 is provided with a shock-absorbing spring 13. One end of the shock-absorbing spring 13 is connected to the inside of the noise reduction frame 5, and the other end of the shock-absorbing spring 13 is connected to the bottom of the mounting frame 2.

[0030] Through the coordinated work of the damping rod 12 and the shock absorbing spring 13 , the vibration generated by the vacuum generator body 1 during operation can be significantly reduced, thereby effectively reducing the noise level during operation.

[0031] like Figure 4 and Figure 5 As shown, a movable block 14 is symmetrically arranged at the bottom of the installation frame 2 , a mounting groove for mounting a protruding rod 15 is provided inside the movable block 14 , a second spring 16 is arranged inside the mounting groove, and one end of the second spring 16 is connected to the protruding rod 15 .

[0032] Through the ingenious cooperation between the protruding rod 15, the second spring 16 and the groove, the noise generated by the vacuum generator body 1 can be further greatly reduced, thereby achieving a quieter working environment.

[0033] like Figure 4 As shown, grooves matching with the protruding rods 15 are formed on the inner walls of both sides of the noise reduction frame 5 .

[0034] The convex rod 15 cooperates with the groove to increase the friction between the mounting frame 2 and the noise reduction frame 5, thereby further reducing the vibration of the vacuum generator body 1.

[0035] like Figure 1 and Figure 4 As shown, the inner wall of the installation frame 2 is provided with a sound absorbing panel 17 .

[0036] The sound absorbing plate 17 can absorb the noise generated by the vacuum generator body 1, thereby ensuring a good working environment.

[0037] like Figure 2 As shown, through holes for mounting the air inlet and air outlet of the vacuum generator body 1 are provided on both sides of the mounting frame 2 .

[0038] The through hole provided on the side wall of the mounting frame 2 facilitates the installation of the vacuum generator body 1 .

[0039] like Figure 2As shown, the size of the through holes at the air inlet and outlet ends is consistent with the size of the filter screen 3.

[0040] By setting the size of the filter 3 to be consistent with the size of the air inlet end and the air outlet end, it is possible to effectively prevent external dust from entering the interior of the vacuum generator body 1.

[0041] The above embodiments only express a multifunctional vacuum generator or several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the attached claims.
