Description

  The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner having a sterilizing function.

  Conventional vacuum cleaners generally include a suction head, a main body, a suction head, and a hose connecting the main body. When the vacuum cleaner operates, the suction head sucks air, dust, and the like through a suction port provided in the suction head. Thereafter, the sucked air and dust enter the main body through a hose, and remove dust, bacteria, etc. in the air by filtering the filter in the main body and decomposing the nano-optical catalyst layer. Finally, the dust The air from which bacteria and the like have been removed is discharged through an exhaust port installed on the main body.

  However, in the air exhausted from the exhaust port, there is still a toxic and harmful residue remaining without being decomposed because it is very small, and it is harmful to the human body.

  In order to solve the above problems, the present invention provides a vacuum cleaner having an excellent sterilizing effect.

  The vacuum cleaner which concerns on this invention is equipped with the suction head, a main body, the hose which connects the said suction head and the said main body, and the filter installed in the said main body. The filter includes a light source module, a photocatalyst, and an adsorbent, the suction head sucks air into the main body, and the photocatalyst absorbs air such as bacteria, disease bacteria, and dust in the main body by excitation of the light source module. By performing decomposition, the adsorbent adsorbs toxic and harmful substances remaining in the decomposed air and small volume of dust, and further purifies the air.

  Compared to the prior art, in the vacuum cleaner according to the present invention, since the adsorbent is installed in the filter, the volume remaining in the air after decomposition is small, and harmful substances that are difficult to decompose are Since it is adsorbed again by the adsorbent, the air can be further purified and the purification effect can be improved.

  The suction head 10 has a substantially rectangular parallelepiped shape, and includes a top surface 11 and a bottom surface 13 installed on the opposite side of the top surface 11. In the center of the bottom surface 13, a rectangular groove 15 that is recessed toward the top surface 11 is formed. A through hole 151 that communicates with the hose 20 is provided at the bottom of the groove 15. Pulleys 50 are respectively installed at the four corners of the bottom surface 13, and each pulley 50 can rotate in various directions. Therefore, the suction head 10 can freely change the direction by the pulley 50 and can clean different places.

  A brush 60 is provided on the bottom surface 13 so as to surround the groove 15. The brush 60 is used to remove dust adhering to the surface of the object. Thereby, dust is easily sucked by the suction head 10. Further, a filtration cover 70 is further installed in the opening of the groove 15. The filter cover 70 has a mesh shape and includes a plurality of filter holes 701. The filter cover 70 can filter large particulate matter (that is, dust).

  The hose 20 is a hollow tubular body, is fixed to the top surface 11 of the suction head 10, and communicates with the groove 15. The hose 20 is used to suck the air sucked by the suction head 10 into the main body 30. In the present embodiment, the hose 20 is made of a metal or a plastic material.

  The main body 30 includes a housing cylinder 31 connected to one end of the hose 20 away from the suction head 10 and a rotating wheel 33 installed at the bottom of the housing cylinder 31. The main body 30 can be freely moved by the rotating wheel 33.

  The filter 40 includes a filtration layer 41, a fan 43, a light source module 45, a photocatalyst 47 corresponding to the light source module 45, and an adsorbing body 49, which are installed in order from the top to the bottom.

  The filtration layer 41 has a flat plate shape and includes a mesh (not shown) penetrating from the upper surface to the lower surface of the filtration layer 41. The mesh is used to filter large particulate matter in the air. The filtration layer 41 is made of a metal or a plastic material.

  The fan 43 is connected to an electric circuit (not shown) and is used to quickly suck air into the filter 40.

  The light source module 45 includes a light board 451 and a plurality of light emitting diodes 453 that are spaced apart from each other on the light board 451. The light board 451 is provided with a plurality of ventilation holes 455 for allowing air to pass therethrough, and the plurality of ventilation holes 455 are respectively installed between the adjacent light emitting diodes 453. The light emitting diode 453 is used to excite the photocatalyst 47 located therebelow. The light emitting diode 453 is a UV light emitting diode that can emit light having a wavelength of 200 nm to 275 nm. In another embodiment, the wavelength of the light emitted from the UV light emitting diode may be 320 nm to 400 nm.

  The photocatalyst 47 is a nano-level metal oxide. The photocatalyst 47 can generate a strong catalytic decomposition function under the action of ultraviolet rays. Thereby, toxic and harmful substances in the air can be effectively decomposed to sterilize various bacteria, and toxins released from bacteria and fungi can be decomposed and rendered harmless. The photocatalyst 47 further has functions such as deodorization and decontamination. In this embodiment, the photocatalyst 47 is nano-level titanium dioxide.

  The adsorbent 49 is used to adsorb a small volume of harmful substances remaining in the air after being decomposed. Thereby, the air can be further purified. In the present embodiment, the adsorbent 49 is activated carbon.

  Referring to FIG. 3, in the vacuum cleaner 1 according to the second embodiment of the present invention, a vibrator 80 is installed in the suction head 10 in order to further improve the effect of the dust removal function of the brush 60. The vibrator 80 drives the brush 60 so as to remove dust and the like adhering to the object surface at a predetermined frequency. As a result, the dust and the like that have been removed are easily sucked by the suction head 10.

  When the cleaner 1 operates, first, the fan 43 rotates and the suction head 10 sucks air by driving the fan 43. Next, the sucked air is sucked into the main body 30 through the hose 20, filtered by the filter 40, and then discharged through the exhaust port 35.

  Since the filtration cover 70 is installed on the suction head 10, large dust in the air sucked by the suction head 10 is filtered by the filtration cover 70. Next, the air filtered by the filter cover 70 enters the main body 30 and sequentially passes through the filtration layer 41, the vent hole 455 of the light source module 45, the photocatalyst 47 and the adsorbent 49. When air passes through the filtration layer 41, large dust or the like in the air is further filtered by the filtration layer 41. Thereby, the first purification is performed. Next, the purified air enters the photocatalyst 47 through the vent hole 455 of the light source module 45. At this time, since the photocatalyst 47 generates a powerful catalytic decomposition function by excitation of the light emitting diode 453, it is possible to decompose dust, bacteria or pathogens in the air and reduce toxic and harmful substances in the air. Since there are some toxic and harmful residues that are still very small and difficult to decompose in the air after being decomposed, they are further passed through the adsorbent 49, and solid fine particles and toxic and harmful residues are present. Is adsorbed by the adsorbent 49. Thereby, the second purification is performed. Finally, the purified air is exhausted through a plurality of exhaust ports 35 formed at the bottom end of the housing cylinder 31 by driving the fan 43.

In the vacuum cleaner 1 of the present invention, the light source module 45 is installed in the housing cylinder 31, the filtration layer 41 is installed above the light source module 45, and the light emitting diode 453 is installed on the lower surface of the light board 451. Therefore, dust or the like does not adhere to the surface of the light emitting diode 453 when the air filtered by the filter layer 41 passes through the vent hole 455 of the light board 451.
Therefore, the light emitting effect of the light emitting diode 453 can be ensured. Further, since the adsorbent body 49 is installed in the main body 30, harmful substances that are small in volume remaining in the air after being decomposed and are difficult to decompose are adsorbed again by the adsorbent body 49. It can be purified and the purification effect can be improved.
