Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a novel lower shell structure of an air filter. Background Art

[0002] An air filter is a device for purifying air. It consists of an air filter inlet pipe, an air filter body assembly (upper shell assembly, lower shell assembly and filter element assembly), and an air filter outlet pipe assembly. The filter element assembly is arranged in the shell in a reasonable structure and is connected to the engine air intake through the outlet pipe assembly to filter various foreign matter in the atmosphere, such as dust, sand, etc.

[0003] The existing patent CN203627022U provides a clamping device for the upper and lower shells of an air filter, which brings the beneficial effects of "the clamping spring is easy to operate at the limited position, and there is no sticking feeling when fastening. Whether the clamping spring is opened or fastened, it is not easy to fall off without the action of artificial external force. The simple and easy-to-implement structure solves the problem that the clamping spring is easy to assemble and not easy to fall off at the same time". Although the U-groove is matched with the size of the notch part to ensure that the clamping spring can only be assembled in the vertical direction so that the end ring gap fits on the cylinder of the overlap block, after the clamping spring is opened, the outer surface of the clamping spring is supported by the notch plane in the overlap block to achieve the limiting effect, but the clamping spring still needs to be rotated during assembly, and is easily restricted by space during assembly. After the assembly is completed, it is still not clamped, but it is limited to make it difficult to loosen and fall off, and the fixation is still not firm. In view of this, a new air filter lower shell structure is proposed. Utility Model Content

[0024] 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.

[0025] See also Figure 1-4 The utility model provides a new technical solution: a new air filter lower shell structure, including an air filter upper shell 1, an air filter upper shell 1 is provided with an air intake pipe 3, an air filter lower shell 2 is provided on the lower surface of the air filter upper shell 1, and an air outlet 4 is provided on the right surface of the air filter lower shell 2;

[0026] The disassembly and assembly mechanism is arranged on the upper housing 1 of the air filter, and is used for disassembling and assembling the air filter housing. The disassembly and assembly mechanism comprises two hollow columns 7, and the two hollow columns 7 are sleeved on the inner surface of the upper housing 1 of the air filter;

[0027] The drain mechanism is arranged in the lower shell 2 of the air filter. The drain mechanism is used to filter the moisture generated when the air inside the air filter is filtered. The drain mechanism includes a drain hole 15. The drain hole 15 is opened on the lower surface of the bottom plate of the lower shell 2 of the air filter.

[0028] Furthermore, two circular holes 8 are formed on the outer surface of the hollow column 7 , and round balls 9 are disposed in the two circular holes 8 .

[0029] Furthermore, the disassembly and assembly mechanism also includes a spring 10 and a ring 11. The spring 10 is fixedly installed in the inner wall of the hollow column 7, and the ring 11 is fixedly installed at the lower end of the spring 10.

[0030] Furthermore, the disassembly and assembly mechanism also includes a fixing rod 12 , which is fixedly sleeved on the inner surface of the ring 11 and slidably sleeved on the inner surface of the hollow column 7 .

[0031] Furthermore, a pull ring 14 is fixedly mounted on the upper end of the fixing rod 12 , and two circular grooves 13 are formed on the outer surface of the fixing rod 12 .

[0032] Furthermore, the drainage mechanism also includes a dustproof net 16, which is fixedly installed on the upper surface of the bottom plate of the lower shell 2 of the air filter. When the new lower shell structure of the air filter is in use, the pull ring 14 is pulled, and the pull ring 14 drives the fixed rod 12 fixedly installed on the lower surface to move upward, and the fixed rod 12 drives the circular ring 11 fixedly sleeved on the outer surface to move upward. While the circular ring 11 moves upward, it applies pressure to the spring 10 fixedly installed on the upper surface to cause it to shrink. At the same time, the circular groove 13 provided on the outer surface of the fixed rod 12 is aligned with the circular hole 8. At this time, the fixed rod 12 no longer applies pressure to the round ball 9, and the round ball 9 shrinks into the hollow column 7. At this time, the hollow column 7 is inserted into the slot 5. At this time, no tension is applied to the pull ring 14, and the spring 10 is no longer under force. The spring 10 expands, and the spring 10 applies a downward thrust to the circular ring 11 fixedly installed at the lower end to cause it to move downward. The ring 11 drives the fixing rod 12 fixed on the inner surface to move downward, and at the same time, the fixing rod 12 hits the round ball 9, making it protrude from the hollow column 7 and be snapped into the snap hole 6 for fixation. At this time, the installation is completed. When it needs to be disassembled, the operation of pulling the pull ring 14 is repeated to contact the snap connection and fix it for disassembly, and the moisture generated in the air filter will be discharged through the drain hole opened on the lower surface of the air filter lower shell 2. The new air filter lower shell structure can quickly install the air filter shell by snap connection, and the disassembly and assembly are convenient and simple to operate. The inside of the air filter can be quickly inspected and repaired, and it does not need to occupy too much space during installation, which is more convenient. In addition, the new air filter lower shell structure can drain the moisture generated inside the air filter through the drain hole 15 to keep the inside dry, and the dustproof net 16 can be used to prevent stains from entering the inside of the air filter, which is more practical.

[0033] Working principle: When the new air filter lower shell structure is used, the pull ring 14 is pulled, and the pull ring 14 drives the fixed rod 12 fixed on the lower surface to move upward, and the fixed rod 12 drives the circular ring 11 fixed on the outer surface to move upward. While the circular ring 11 moves upward, it applies pressure to the spring 10 fixed on the upper surface to shrink it. At the same time, the circular groove 13 on the outer surface of the fixed rod 12 is aligned with the circular hole 8. At this time, the fixed rod 12 no longer applies pressure to the round ball 9, and the round ball 9 shrinks into the hollow column 7. At this time, the hollow column 7 is inserted into the slot 5, and the pull ring 14 is no longer pressed. The ring 14 applies a pulling force, and at the same time, the spring 10 is no longer under force, and the spring 10 expands. The spring 10 applies a downward thrust to the circular ring 11 fixedly installed at the lower end, causing it to move downward. The circular ring 11 drives the fixing rod 12 fixedly sleeved on the inner surface to move downward. At the same time, the fixing rod 12 hits the round ball 9, causing it to protrude from the hollow column 7 and be snapped into the snap hole 6 for fixation. At this time, the installation is completed. When it needs to be disassembled, the operation of pulling the pull ring 14 is repeated to contact the snap connection and fix it for disassembly, and the moisture generated in the air filter will be discharged through the drain hole opened on the lower surface of the lower shell 2 of the air filter.
