Description

Hand-operated cleaning filter

Technical Field

The utility model relates to the field of filters, in particular to a hand-operated cleaning filter.

Background

The existing dust remover is large in size, inconvenient to move in use in various environments or damaged in the moving process, and large-particle dust is sucked into an air inlet and the like together in the actual use process of equipment, so that inconvenience is brought to a user and loss is caused.

The dust remover on the market is generally of a structure of an air inlet, an air outlet, a filter cylinder and an exhaust device, harmful smoke dust and industrial waste gas enter from the air inlet, after being filtered by the filter cylinder, the harmful smoke dust and industrial waste gas flow through the exhaust device and are discharged from the air outlet, after the dust remover is used for a long time, a large amount of dust exists on the filter cylinder, in order to fall off the dust on the filter cylinder, the dust on the filter cylinder is blown by an ash removing device to fall onto an ash collecting box, the existing ash removing device blows air into the filter cylinder through pulse control, high-pressure air blows to the filter cylinder, dust particles fall off under the action of instant high-pressure air flow, but in the environment of installing an air compressor under narrow space or no corresponding condition, the equipment cannot clean the filter cylinder through a blowback device, so that a filtering system is extremely fast invalid. The filtering device is wholly disassembled to be cleaned, so that the working time is delayed, and meanwhile, manpower and material resources are required to be spent.

In chinese patent application No. (202320148529.2), a manual ash removal filter is disclosed, in which a baffle is also disposed at an air inlet, but the baffle has a very small effect of filtering large particle dust, and the rocker arm can make the rocker arm rotate forward and reverse to clean the inside of the filter cartridge, so that the rocker arm rotates forward or reverse to make the inner shaft apply force to the filter cartridge in practical process, thereby causing the inner shaft and the filter cartridge to fall off.

Disclosure of Invention

The technical scheme of the utility model is realized as follows: the utility model provides a clean filter of hand formula, includes the quick-witted case, the quick-witted case includes air intake, air outlet and the wind channel of intercommunication air outlet and air intake, the quick-witted incasement is equipped with first filter equipment, second filter equipment and third filter equipment, first filter equipment, second filter equipment and third filter equipment are located the wind channel in proper order, and wherein, first filter equipment is located between second filter equipment and the air intake, second filter equipment is for straining the section of thick bamboo, straining and straining a pivoted inner shaft relatively to be equipped with in the section of thick bamboo, the inner shaft circumference is provided with the clean part that can rotate along with the inner shaft, a rocking arm, rotatably installs in the quick-witted incasement, still includes a one-way clutch, the rocking arm is through this one-way clutch drive inner shaft.

Further, a dust collecting box is arranged below the first filtering device and used for collecting large-particle dust blocked by the first filtering device.

Further, the first filtering device is a fireproof net.

Further, the cleaning component is a wiper blade.

Compared with the prior art, the utility model has the following advantages: the rocker arm drives the inner shaft through the one-way clutch, and the inner shaft drives the cleaning component to clean the inner wall of the filter cylinder when the rocker arm rotates forward.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 3, the present embodiment provides a hand-operated cleaning filter, including a chassis 1, the chassis 1 includes an air inlet 2, an air outlet 3, and an air duct communicating the air outlet 3 and the air inlet 2, a first filter device 4, a second filter device 5, and a third filter device 6 are disposed in the chassis 1, the first filter device 4, the second filter device 5, and the third filter device 6 are sequentially disposed on the air duct, that is, the air duct passes through the first filter device, the second filter device, and the third filter device, wherein the first filter device 4 is disposed between the second filter device 5 and the air inlet 2, the second filter device 5 is a filter cartridge 51, an inner shaft 52 rotatable relative to the filter cartridge 51 is disposed in the filter cartridge 51, a cleaning component rotatable with the inner shaft 52 is disposed circumferentially in the inner shaft 52, a rocker arm 54 is rotatably mounted in the chassis 1, and the rocker arm 54 drives the inner shaft 52 through the one-way clutch 7.

When the fan starts to work, air enters from the air inlet 2 and then is filtered by the first filtering device 4, large-particle dust in the air is isolated, the first filtering is achieved, then the air enters the second filtering device 5, the second filtering device 5 is the filter cartridge 51, the filter cartridge 51 carries out the second filtering on the air, after the second filtering is finished, the air enters the third filtering device 6 along the air channel, then the filter core in the third filtering device 6 carries out the third filtering, and then is sucked into the fan, and finally is discharged out of the filter from the air outlet 3, after the filter is finished, only the rocker arm 54 is needed to shake, the rocker arm 54 drives the one-way clutch 7 in the filter cartridge 51 (the working principle of the one-way clutch is not repeated in the prior art), and the inner shaft 52 and the filter cartridge 51 are oppositely arranged, so that when the rocker arm 54 rotates positively, the inner shaft 52 generates a reverse torsion force on the filter cartridge 51, the inner shaft 52 cannot separate from the filter cartridge 51, and when the rocker arm 54 rotates negatively, the inner shaft 52 cannot rotate, the inner shaft 52 cannot separate from the filter cartridge 51, the inner shaft 51 cannot be cleaned simply, the filter cartridge 52 cannot be cleaned conveniently, and the filter cartridge can be cleaned conveniently.

Further, the first filtering device 4 is a fireproof net 41. The fireproof net 41 can isolate large-particle dust before entering the filter cartridge 51, and the large-particle dust can be concentrated and falls into the dust box 8 below the air inlet, so that the filter cartridge 51 can be protected from damage while cleaning is convenient.

Further, the cleaning member is a wiper blade 10.

The above examples are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto, and any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present utility model are included in the scope of the present utility model.
