Description

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention
The present invention relates to a dust collector, and more particularly, to a water filtered dust collector.
2. Description of Related Arts
An ordinary dust collector has a dust chamber or is equipped with an extra dust bag based on the dust chamber. As each type of dust collector has a different model, many factors such as the shape and the operation method of each dust collector should be considered when manufacturing the corresponding dust chamber. Also, in general, the dust chamber can be used only once, or it should be cleaned after being used for several times. But after being used for a too long time, more and more dust hard to be cleaned will accumulate. And therefore, the reusability of the dust chamber is affected, the use-cost of the product is increased and it is not environmentally friendly. And for the dust collector with a dust bag, the material of the dust bag may generally allow both air and dust pass through. The dust collector is used to clean the dust in the room, but the dust will suspend in the air through the dust bag of the dust collector. Also, the material of such a dust bag is generally soft, and therefore, some special material is needed to connect and fix with the dust inlet port of the dust collector, which is inconvenient for the users replacing the dust bag. Furthermore, such dust bag can be used only once, so it's not environmentally friendly.

SUMMARY OF THE PRESENT INVENTION

The object of the present invention is to overcome the drawbacks of prior art, and to provide a water filtered dust collector, which can be recycled, easy to clean and can satisfy the requirements for environmental protection.
To realize the above technical solution, the present invention adopts the following technical solution:

A battery package is disposed at one end of the housing, and a suction nozzle is disposed at the other end. A suction nozzle mounting communicating with the suction nozzle is disposed at the bottom of the suction nozzle. A suction nozzle fixing bush is disposed between the suction nozzle mounting and the housing to connect and fix them. An electric motor driven by batteries in the battery package and fan blades driven by the electric motor are disposed in the suction nozzle fixing bush and the housing. A water vessel for holding water is disposed in parallel to the suction nozzle on the suction nozzle mounting. An air steering pipe, which may redirect the water-filtered air, is disposed at a position corresponding to the suction nozzle on an end surface far from the suction nozzle of the suction nozzle mounting. An air inlet pipe is disposed on the septum of the suction nozzle fixing bush, with one end inserted into the water vessel to communicate the suction nozzle fixing bush with the water vessel.
The air steering pipe extends in a direction opposite to the direction the air inlet pipe extends in the suction nozzle fixing bush to form a cavity, which corresponds to the center of the fan blades.
The air inlet pipe is a straight pipe with an elbow of 90 degrees at the end of the water vessel.
The water vessel connects with the suction nozzle mounting, and a boss is disposed on the suction nozzle mounting on which the water vessel can be enclosed removably. The air inlet pipe extends through the suction nozzle mounting and is located at the center of the water vessel, and the connection between the suction nozzle mounting and the air inlet pipe is a tight connection.
The battery package and the housing are fixed and connected by a connection plug.
The connection plug has a body, with two elastic clip pins at one end of the body, wherein the width of the two ends of the body is greater than that of the clip pins, and the two ends are disposed within the clip socket at a corresponding position of the housing.

DETAILED DESCRIPTION OF THE INVENTION

The present invention is further described with referent to the accompanying drawings as follows.
As shown in FIGS. 1 to 4, the water filtered dust collector comprises a housing 1 with a handle that is consisted of front and back housings 12,14, which are engaged with each other. A battery package 2 is disposed at one end of the housing, and a suction nozzle 3 is disposed at the other end. A suction nozzle mounting 32 communicating with the suction nozzle is disposed at the bottom of the suction nozzle. A suction nozzle fixing bush 4 is disposed between the suction nozzle mounting and the housing to connect and fix them. An electric motor 5 driven by the batteries in the battery package and fan blades 6 driven by the electric motor are disposed in the suction nozzle fixing bush and the housing. A water vessel 7 for holding water is disposed in parallel to the suction nozzle on the suction nozzle mounting. An air steering pipe 42, which can redirect the water-filtered air, is disposed at a position corresponding to the suction nozzle on an end surface far from the suction nozzle of the suction nozzle mounting. An air inlet pipe 44 is disposed on the septum of the suction nozzle fixing bush, with one end inserted into the water vessel to communicate the suction nozzle fixing bush with the water vessel. The air steering pipe 42 extends in a direction opposite to the direction the air inlet pipe 44 extends in the suction nozzle fixing bush 4 to form a cavity 46, which corresponds to the center of the fan blades 6. The air inlet pipe 44 is a straight pipe with an elbow 48 of 90 degrees at the end of the water vessel 7. The water vessel 7 connects with the suction nozzle mounting 32, and a boss 322 is disposed on the suction nozzle mounting, on which the water vessel can be enclosed removably. The air inlet pipe 44 extends through the suction nozzle mounting and is located at the center of the water vessel, and the connection between the suction nozzle mounting and the air inlet pipe is a tight connection. The battery package 2 and the housing 1 are fixed and connected by a connection plug 8. The connection plug 8 has a body 82, with two elastic clip pins 84 at one end of the body, wherein the width of the two ends of the body is greater than that of the clip pins, and the two ends are disposed within the clip socket 16 at a corresponding position of the housing 1. A handheld handle 18 is formed after engaging the front and back housings 12,14. And an exhaust slot 9, which may exhaust the air from the air steering pipe 42 out of the dust collector, is disposed at the position opposite to the handle. The water vessel 7 may be cylindrical. Screws 10 are used to fix them in many places when assembling the front and back housings.
When assembling, fill the water vessel 7 with water at first, with the sucker downwards, and the water surface in the water vessel lower than the opening of the air inlet pipe. Then enclose it on the boss 322 on the suction nozzle mounting 32 of the dust collector. Thus a layer of special water-solidifiable glue is disposed previously between them such that an airproof effect may be achieved after they are connected. When being used, a control switch 9 is turned on first to communicate the electric motor 5 with the batteries in the battery package 2, such that driven by the electric motor, the fan blades 6 begin rotating and a suction is generated, drawing out all the air in the suction nozzle fixing bush 4, the suction nozzle mounting 32 and the dust collector to form a vacuum state. Thus a strong suction is generated at the sucker 34 of the suction nozzle 3. And therefore, when the sucker contacts the object surface to be cleaned, the dust is sucked in by the strong suction via the sucker, moves towards the suction nozzle mounting 32 along the suction nozzle, and then enters the water vessel 7 filled with water along the air inlet pipe 44. Because an air inlet pipe with an elbow 48 of 90 degrees is disposed at the end of the air inlet pipe 44, water in the water vessel will not flow back into the suction nozzle fixing bush. After entering the water pipe, the air with dust contacts the water surface, and will suspend in the water, instead of adhering to the pipe wall after being filtered by water. So the air is without dust when entering the air steering pipe 42. Subsequently the clean air is exhausted out of the dust collector via the exhaust slot 9. Finally the water vessel can be disassembled to replace the water, and then enclosed on the suction nozzle mounting for reuse.
As described above, compared with prior art, the water filtered dust collector has the following advantages: easy for cleaning, as it is filtered by water; easy for replacing, as it is convenient to assemble and disassemble the device collecting dust; environmentally friendly, as the water vessel used for collecting dust and filtering can be reused; and reducing the use-cost, as the water vessel can be made into various shapes and thus has a high applicability.
