Description
Technical Field
[0001] The utility model belongs to the technical field of chainsaws, and particularly relates to an environment-friendly chainsaw with a filtering and collecting mechanism. Background Art
[0002] The air filter of a chainsaw is used to filter impurities and dust in the air, and collect and intercept the impurities and dust in the air outside the filter element to protect the engine from damage. The air filter is usually connected to the air intake of the chainsaw to ensure that the air inhaled by the engine is clean and pure;
[0003] At present, the air filter installed at the air intake of the chainsaw usually consists of a skeleton and an integral filter element located outside the skeleton. The skeleton is used to support the filter element. Such an air filter is fixed at the air intake by four bolts at the four corners. Since the filter element needs to be cleaned and replaced regularly, when cleaning the filter element, it is basically necessary to disassemble and clean and maintain it every time the chainsaw is used once, so as to avoid accumulating more impurities and dust and affecting the air power of the chainsaw. Four bolts need to be disassembled each time the filter element is cleaned or replaced, which may be rather troublesome, especially in the wild or in an environment where it is difficult to use tools. When replacing the filter element, since the skeleton and the filter element are of an integral structure, the whole needs to be disassembled and replaced, increasing the cost.

The locking knob penetrates through the pressing plate and the support skeleton and is threadedly connected with the internal thread hole, thereby encapsulating the filter element between the support skeleton and the pressing plate.
[0010] Preferably, the support skeleton includes a bottom plate docked on the top of the perforated sealing plate and a core shell integrally formed with the bottom plate and located inside the filter element. The core shell is evenly distributed with hollow holes.
[0011] Preferably, a circular through hole sleeving the outer side surface of the annular ring is formed on the bottom plate, and a guiding hole for the insertion of a locking bolt is formed at the center of the top of the core shell.
[0012] The circular through hole and the hollow holes can help fix the filter element and ensure that air can smoothly pass through the filter element.
[0013] Preferably, a rectangular block extending into the inside of the filter element and abutting against the core shell is provided at the bottom of the pressing plate, and an insertion hole penetrating the rectangular block and cooperating with the locking knob for insertion is formed on the pressing plate.
[0014] The rectangular block and the insertion hole on the pressing plate cooperate with the design of the filter element and the core shell to ensure easy disassembly while fixing the filter element.
[0015] Compared with the prior art, the technical effects and advantages of the present utility model are:
[0016] The air filter on the environment-friendly chainsaw with a filtering and collecting mechanism is fixed above the air inlet box through a locking knob, making the cleaning and replacement of the filter element more convenient.

[0017] A perforated sealing plate is provided above the air inlet box, an annular ring is provided at the top, a cross is provided inside the air inlet box, and an internal thread hole is provided at the center of the cross. The internal thread hole facilitates the insertion and screwing of the locking bolt. The support skeleton includes a bottom plate and a core shell. The bottom plate is provided with through holes, and the core shell is provided with hollow holes. These designs help fix the filter element and ensure that air can smoothly pass through the filter element. A circular through hole sleeving the outer side surface of the annular ring is also formed on the bottom plate, and a guiding hole for the insertion of a locking bolt is formed at the center of the top of the core shell. The support skeleton and the pressing plate encapsulate the filter element on the outer side surface of the core shell and between the bottom plate and the pressing plate, and then are locked and fixed at the center of the cross through a locking bolt. These designs contribute to the disassembly and installation of the filter element.
[0018] Locking the pressing plate, the filter element and the support skeleton on the air inlet box through a locking bolt reduces the time for maintenance and replacement of the filter element, allows the user to complete the maintenance work faster, and improves work efficiency. The chainsaw with a filtering and collecting mechanism can effectively filter and collect impurities and dust in the air, protect the engine from damage, and contribute to improving the service life and environmental protection performance of the chainsaw.
