Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment of gasoline generator sets, and in particular relates to an air filter for gasoline generator sets. Background Art

[0002] When in use, gasoline generator sets require oxygen to provide an oxidant for gasoline combustion. During this process, the air entering the generator set is filtered through an air filter to prevent impurities from entering the combustion chamber.

[0003] The existing air filter includes a shell, a cover plate and a filter screen. The filter screen is detachably mounted at the air inlet on the shell through the cover plate. The cover plate is a breathable grille structure. The cover plate is generally mounted on the shell by locking it with multiple bolts during installation. When the filter screen is replaced, multiple bolts need to be loosened or tightened. The filter screen is replaced after being used for a period of time, which results in the bolts needing to be tightened or loosened multiple times, resulting in the threaded holes accommodating the bolts being damaged by thread slippage. In addition, the existing filter screen is generally installed at the end of the shell or the side of the shell, resulting in external dust particles being adsorbed on the filter screen, thereby affecting the speed at which gas passes through the filter screen, greatly reducing the practicability of the equipment.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] refer to Figure 1-2 As shown, the utility model provides an air filter for a gasoline generator set, comprising: a shell 1 connected to an air intake duct of the generator set, an air inlet 19 is provided at the bottom of the shell 1, a slot 3 extending to the inside is transversely provided on the side of the shell 1, a mounting frame 2 and a filter assembly are sequentially provided in the slot 3 from the outside to the inside, a storage space for accommodating the filter assembly is formed in the mounting frame 2, and the mounting frame 2 is plugged and installed in the slot 3.

[0025] Combination Figure 2 As shown, a latch rod 7 for limiting the position of the mounting frame 2 is also mounted on the housing 1 , and one end of the latch rod 7 can be plugged into the mounting frame 2 .

[0026] As described above, when using the shell 1, air inlet 19, slot 3 and mounting frame 2 provided by the utility model, the filter assembly can be set at the bottom of the shell 1 through the air inlet 19. When the equipment is not in use, the particulate dust on the filter assembly automatically falls under gravity to avoid the filter assembly being blocked. The filter assembly on the mounting frame 2 can be pushed into the shell 1 through the slot 3. When replacing the filter assembly, it is only necessary to adjust the mounting frame 2 laterally, thereby realizing rapid disassembly and assembly of the filter assembly.

[0027] Further, in order to move the latch rod 7, refer to Figure 2 As shown, a latch groove 5 connected to the slot 3 is provided in the housing 1, and a latch rod 7 is at least partially movably installed in the latch groove 5. A latch hole 8 coaxial with the latch groove 5 is provided on the mounting frame 2, and one end of the latch rod 7 can be inserted in the latch hole 8, and a first spring 6 connected to the latch groove 5 is installed at the end of the latch rod 7 away from the latch hole 8, and a shift block 4 connected to the latch rod 7 is movably installed outside the housing 1. The latch rod 7 is movably inserted and installed in the shell 1 through the latch groove 5. When the installation frame 2 drives the filter assembly into the shell 1, the latch hole 8 on the installation frame 2 is on the axial center line of the latch groove 5. At this time, the elastic force of the first spring 6 can drive one end of the latch rod 7 to be inserted into the latch hole 8, thereby preventing the installation frame 2 from driving the filter assembly to be removed from the shell 1. The latch rod 7 can be moved by the shift block 4, so that one end of the latch rod 7 can be pulled out of the latch hole 8. At this time, the installation frame 2 can be pulled out of the shell 1 to facilitate the replacement of the filter assembly.

[0028] In the present utility model, combined with Figure 2-3 As shown, a knocking mechanism for knocking the filter assembly is also installed inside the shell 1 of this embodiment. The knocking mechanism is installed above the filter assembly and rises and falls with the airflow. When the knocking mechanism descends, the bottom end of the knocking mechanism knocks on the filter assembly.

[0029] Combination Figure 2 As shown, the knocking mechanism includes a mounting frame 18 and a connecting rod 13 longitudinally inserted into the mounting frame 18, a wind blocking disk 12 is provided on the top of the connecting rod 13, and a knocking ball 14 abutting against the filter assembly is provided on the bottom of the connecting rod 13.

[0030] As mentioned above, when using the knocking mechanism provided by the utility model, the mounting frame 18 in the knocking mechanism provides a lifting and lowering mounting position for the connecting rod 13, and the two ends of the connecting rod 13 are respectively installed with the choke plate 12 and the knocking ball 14. When the external airflow enters the shell 1, the passing airflow will pass through the choke plate 12, and the choke plate 12 can be driven to rise by the airflow. In this process, the knocking ball 14 is driven to rise by the connecting rod 13. When the airflow weakens, under gravity, the choke plate 12 and the knocking ball 14 fall onto the filter assembly under gravity, thereby vibrating the dust on the filter assembly through the knocking ball 14 to prevent the filter assembly from being blocked.

[0031] In the present utility model, combined with Figure 2 As shown, a liftable connecting ring seat 17 is also installed in the shell 1 of this embodiment. The connecting ring seat 17 is used to seal the gap between the shell 1 and the filter assembly. The bottom end of the connecting ring seat 17 can be plugged into the filter assembly, and the mounting frame 18 is installed on the inner wall of the connecting ring seat 17.

[0032] As mentioned above, when using the connecting ring seat 17 provided by the utility model, after the installation frame 2 drives the filter assembly into the shell 1, the connecting ring seat 17 descends, so that the connecting ring seat 17 can block the gap between the shell 1 and the filter assembly to prevent external dust from entering the shell 1 through the gap.

[0033] Further, in order to allow the connection ring seat 17 to be raised and lowered in the housing 1, refer to Figure 2 As shown, mounting seats 10 are installed on the inner walls of both symmetrical sides of the housing 1, and two guide rods 11 on the connecting ring seat 17 are movably installed on each mounting seat 10, and a second spring 9 sleeved on the corresponding guide rod 11 is installed between each mounting seat 10 and the connecting ring seat 17. The mounting seat 10 provides a lifting position for the guide rod 11, so that the connecting ring seat 17 can be lifted and lowered in the housing 1. The outer side of the bottom of the connecting ring seat 17 is provided with a chamfer. When the mounting frame 2 enters the housing 1, the edge position of the mounting frame 2 will dock at the chamfer, thereby driving the connecting ring seat 17 to rise. When the mounting frame 2 enters the housing 1, the connecting ring seat 17 is automatically inserted into the filter assembly under the elastic force of the second spring 9. The outside of the connecting ring seat 17 can be wrapped with rubber. When the connecting ring seat 17 is inserted into the filter assembly, the connecting ring seat 17 blocks the gap between the housing 1 and the filter assembly, so that the gas entering the housing 1 can only enter through the filter assembly.

[0034] In the present utility model, combined with Figure 2As shown, the filter assembly of this embodiment includes a filter screen 15 and a skirt 16 installed around the edge of the filter screen 15. A first mounting bin and a second mounting bin are sequentially penetrated through the mounting frame 2 from top to bottom. The outer diameter of the first mounting bin is greater than the inner diameter of the second mounting bin. A storage space is formed in the first mounting bin, and the skirt 16 is embedded in the first mounting bin.

[0035] As mentioned above, when using the filter assembly provided by the utility model, the skirt 16 in the filter assembly provides an installation position for the filter screen 15, and at the same time, the skirt 16 is embedded and installed on the installation frame 2 through the first installation bin, so that the filter screen 15 can be brought into the shell 1 through the installation frame 2, and the external airflow can pass through the filter screen 15 and enter the shell 1 through the second installation bin and the first installation bin.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
