Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a vacuum internal circulation type vacuum cleaner. Background Art

[0002] Most of the current vacuum cleaners suck in air and dust through the air inlet, and then pass through the filter net to discharge the filtered air out of the vacuum cleaner through the exhaust port. At present, there are the following technical problems: (1) The suction port of the vacuum cleaner head can only suck up part of the dust and garbage on the ground. If there is heavy garbage or dust stuck to the ground, it will be difficult to clean, thus affecting the vacuuming effect. (2) During the vacuuming process, some tiny dust cannot be completely filtered and will continue to cause secondary pollution when discharged through the exhaust port. Especially in the storage warehouse of a chemical plant, some harmful particles and dust will cause secondary pollution if not handled properly, which will not only pollute the air, but also affect people's life and health. Or in the storage warehouse where flammable and explosive substances are stored, if the flammable substances are not cleaned up, there will be huge fire hazards. Utility Model Content

[0021] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0022] like Figure 1 As shown, the vacuum internal circulation vacuum cleaner includes a vacuum head 10 and a vacuum cleaner body 20. The vacuum head 10 and the vacuum cleaner body 20 can be connected by a hose, and the inside of the hose is divided into two channels for air inlet and air exhaust (the hose is not illustrated in the figure, and a person skilled in the art can easily implement it, so it will not be described here).

[0023] refer to Figure 2 and Figure 3 The dust collector head 10 includes an outer shell 11 and an inner shell 12. The outer shell 11 is formed with air intake ports 13 around the bottom, and the outer shell 11 is formed with a dust collector head air intake channel 14 connected with the air intake port 13; the inner shell 12 is formed with an air exhaust port 15 at the bottom, and the inner shell 12 is formed with a dust collector head exhaust channel 16 connected with the air exhaust port 15; the air intake port 13 is arranged around the circumference of the air exhaust port 15, and the dust collector head structure is ingeniously and reasonably designed.

[0024] refer to Figure 4 The vacuum cleaner body 20 includes a casing 21 and a dust suction fan 22 installed in the casing 21, and a main body suction channel and a main body exhaust channel 23 are formed in the casing 21; a dust collecting chamber 24, a filter water tank 25, and an internal circulation suction chamber 26 are arranged in sequence from the direction of air flow in the main body suction channel, and a filter bag is detachably installed at the dust collecting chamber 24; the air inlet of the dust suction fan 22 is connected to the internal circulation suction chamber 26, and in order to further protect the motor, a filter cover 27 is arranged at the air inlet of the dust suction fan 22; the air outlet of the dust suction fan 22 is connected to the main body exhaust channel 23.

[0025] refer to Figure 4 and Figure 5A plurality of filter meshes 28 are installed in the inner circulation suction chamber 26. The filter meshes 28 are preferably distributed in a circular array, and gaps are formed between adjacent filter meshes 28. The filter meshes 28 are S-shaped curved. With this design, on the one hand, the filter meshes 28 can effectively adsorb and filter the micro-particles in the wet air precipitated from the filter water tank 25, and on the other hand, the system operation resistance can be minimized and the dust collection efficiency can be improved.

[0026] refer to Figure 4 and Figure 6 , the working principle of the utility model is as follows:

[0027] During operation, the dust collecting head 10 and the vacuum cleaner body 20 are connected by a hose, and the dust collecting fan 22 is started to form a vacuum environment through the air intake ports 13 around the dust collecting head 10, and the original air in the internal circulation suction chamber 26 is circulated. The internal air circulation is driven by the dust collecting fan 22 to suck in the air with dust from the air intake ports 13 around the dust collecting head 10, and then enter the main suction channel of the vacuum cleaner body 29. When the air with dust passes through the dust collecting chamber 24, large particles of impurities in the air are filtered and collected by the filter bag, and the air after the initial filtration enters the filter water tank 25. After the micro particles in the air are blocked by water, the precipitated gas enters the internal circulation suction chamber 26, and after further adsorbed and filtered by the filter mesh 28, it enters the main exhaust channel 23 through the filter mesh cover 27, and is finally discharged from the exhaust port 15 through the exhaust channel 16 of the dust collecting head, thereby fully improving the dust collection and filtering effect, and will not cause secondary pollution to the environment. In addition, since the air intake port 13 is arranged around the exhaust port 15, the clean air discharged from the exhaust port 15 can blow up the dust on the surrounding side, which is conducive to the dust suction head to suck in the dust, thereby greatly improving the dust suction effect.

[0028] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
