Description

vacuum cleaner

The invention relates to a vacuum cleaner, in particular to a vacuum cleaner with a sterilization function.

A conventional vacuum cleaner generally includes a dust suction head, a dust suction pipe connected to the dust suction head, and a body connected to the dust suction pipe. In operation, the vacuum cleaner sucks gas and impurities through the air inlet of the dust suction head, and then enters the body through the dust suction pipe, and then filters through the filter in the body and degrades the nano-optical catalytic layer to remove the gas. Dust, bacteria or germs, and finally the gas is exhausted through the exhaust port on the body.

However, due to the degradation of dust, bacteria or germs in the gas, there are still extremely small, toxic and harmful residues that are difficult to degrade. If this part of the gas with harmful residues is directly discharged, it will cause greater harm to the human body.

In view of this, it is necessary to provide a vacuum cleaner with good sterilization effect.

A vacuum cleaner comprising a dust suction head, a dust suction pipe connected to the dust suction head at one end, and a body connecting the dust suction pipe away from one end of the dust suction head, wherein the filter body is disposed in the machine body, and the vacuum cleaner head sucks gas into the body during operation After being filtered through a filter in the body, it is discharged from the exhaust port of the body.

In the vacuum cleaner of the present invention, since the filter body of the vacuum cleaner is provided with an adsorbing body, it can further remove a small amount of residual toxic and harmful components which are not easily degraded in the degraded gas, so that the air is further purified. Therefore, the purification effect is improved.

Referring to FIGS. 1 and 2, the vacuum cleaner 1 of the present invention includes a dust suction head 10, a dust suction pipe 20 whose one end is connected to the dust suction head 10, a body 30 that connects the other end of the dust suction pipe 20, and a filter 40 that is located inside the body 30.

The dust suction head 10 has a substantially rectangular parallelepiped shape, and includes a top surface 11 and a bottom surface 13 which are parallel to and spaced apart from the top surface 11. A central portion of the bottom surface 13 of the cleaning head 10 is recessed toward the top surface 11 to form a rectangular recess 15 . A through hole 151 is formed at a bottom end of the groove 15. The through hole 151 and the dust suction pipe 20 communicate with each other. Pulleys 50 are respectively disposed at four corners of the bottom surface 13 of the dust suction head 10. Each pulley 50 can be rotated in all directions. The dust suction head 10 is freely steered by the pulley 50 to facilitate cleaning of debris located at different positions.

A brush 60 surrounds the recess 15 and is disposed on the bottom surface 13. The brush 60 is used to pat the attached impurities on the surface of the object to make it easy to be sucked by the dust suction head 10. Preferably, a filter cover 70 may be disposed at 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 larger particles.

The dust suction pipe 20 is a hollow pipe body that is fixed to the top surface 11 of the dust suction head 10 and communicates with the groove 15 . The dust suction pipe 20 is for transmitting the gas sucked from the dust suction head 10 into the body 30. In this embodiment, the dust suction pipe 20 can be made of metal or plastic material.

The body 30 includes a housing tube 31 that connects the end of the dust suction tube 20 away from the cleaning head 10 and a wheel 33 that is disposed at the bottom of the housing tube 31. The body 30 is free to move under the action of the runner 33.

The filter 40 is located in the receiving cylinder 31, and includes a filter layer 41, a fan 43, a light source module 45, a photocatalyst 47 coupled to the light source module 45, and a photocatalyst 47. Adsorbent body 49.

The filter layer 41 is a flat plate body including a plurality of meshes (not shown) penetrating the upper and lower surfaces of the filter layer 41. The mesh is used to collect larger particulate matter in the gas. The filter layer 41 can be made of a metal material or plastic.

The fan 43 is coupled to a corresponding circuit (not shown) for rapidly drawing gas into the filter 40.

The light source module 45 includes a light board 451 and a plurality of light emitting diodes 453 disposed on the light board 451. An air guiding hole 455 through which a gas passes is formed between the light-emitting diodes 453 and the light-emitting diodes 453. The light emitting diode 453 is used to excite the photocatalyst 47 located directly below it. The light-emitting diode 453 is an ultraviolet light-emitting diode that emits light having a wavelength of 200 nm to 275 nm. In other embodiments, the wavelength of light emitted by the ultraviolet light emitting diode may also be 320-400 nm.

The photocatalyst 47 is a nano-scale metal oxide, which can generate a strong catalytic degradation function under the action of ultraviolet light, can effectively degrade toxic and harmful substances in the gas, kill various bacteria, and can release bacteria or fungi. The toxin is decomposed and harmlessly treated, and also has functions such as deodorization and anti-fouling. Preferably, the photocatalyst 47 is nano-sized titanium dioxide.

The adsorbent 49 is configured to adsorb a small amount of harmful substances remaining in the degraded gas, thereby further purifying the gas. Preferably, the adsorbent 49 is activated carbon.

In this embodiment, the filter layer 41, the fan 43, the light source module 45, the photocatalyst 47, and the absorbing body 49 can be freely detached and mounted to facilitate cleaning and loop utilization.

In the second embodiment, referring to FIG. 3, in order to further improve the flapping effect of the brush 60, a motor vibrator 80 may be disposed in the dust collecting head 10, and the motor vibrator 80 drives the brush 60 to beat at a certain frequency. The foreign matter attached to the object makes it easy to be sucked by the dust suction head 10.

When the vacuum cleaner 1 is in operation, the blades of the fan 43 rotate. Under the driving force of the fan 43, the dust collecting head 10 sucks in gas and conducts through the dust suction pipe 20 to the filter 40 through the filter. The filtration of 40 is finally discharged through the air outlet 35.

Since the filter head 70 is provided on the dust suction head 10, large foreign matter in the gas sucked from the dust suction head 10 is adsorbed to the filter cover 70. Then, during the downward movement of the air in the height direction of the body 30 by the driving force, the air passes through the filter layer 41, the air guiding holes 455 of the light source module 45, the photocatalyst 47 and the adsorbing body 49. When the gas passes through the filter layer 41, the bulky impurities in the gas will be blocked by the filter layer 41 for the initial purification, and then the portion of the air after the initial purification enters the photocatalyst 47 through the air guiding holes 455 on the lamp plate 451 of the light source module 45. Since the photocatalyst 47 at this time is excited by the ultraviolet light emitting diode 453, the photocatalyst 47 generates a strong degradation function. The photocatalyst 47 degrades impurities, bacteria or germs in the passing gas, thereby reducing harmful and toxic components in the gas. Some of the more minute particulate impurities or some toxic and harmful substances that are difficult to degrade remain in the degraded gas. When the air passes through the adsorbent 49, the fine solid particles and the remaining partially toxic and harmful components are adsorbed to the adsorbent 49, thereby further purifying the air. The purified gas is discharged from the plurality of air outlets 35 provided near the bottom end of the housing tube 31 by the driving action of the blower 43.

In the vacuum cleaner 1 of the present invention, the light source module 45 is located inside the housing tube 31, and a filter layer 41 is disposed above the light source module 45, and the light emitting diode 453 is located at the light board. Below the 451, when the gas filtered through the filter layer 41 passes through the air guiding holes 455 on the lamp board 451, impurities are not easily formed on the surface of the light-emitting diode 453, thereby ensuring the light-emitting effect of the light-emitting diode 453. In addition, the sterilizing effect generated by the cleaning head can be ensured; on the other hand, since the additional lamp holder or the lamp tube is not disposed in the cleaning head 10, the air intake area in the cleaning head 10 is increased, thereby improving the work of the vacuum cleaner. Finally, since the body of the vacuum cleaner 1 is provided with an adsorbing body 49, it can further remove the small amount of residual toxic and harmful components which are not easily degraded in the degraded gas, so that the air is further purified. Improve its purification effect.
