DETAILED DESCRIPTION OF THE FIRST EMBODIMENTS

[0028] With reference to FIG. 1, a mobile sterilization vehicle 100 according to a preferred embodiment of the present invention comprises: a body 1, a drive system 2, a water absorption rake 3, a brush disc 4, an air inlet 5, a sterilization structure 200, a filter 6, an air outlet 7, a storage tank 8, an accommodation box 9, and a power supply P.

[0029] Referring to FIG. 1, the body 1 includes a chassis 101 and a wheel set 102 (only a wheel of the wheel set is shown).

[0030] The drive system 2 is disposed on a front end of the body 1 (i.e. the chassis 101) and is electrically connected with the power supply P so as to control the body 1 to move.

[0031] The water absorption rake 3 is fixed on a rear end of the body 1 (i.e. the chassis 101).

[0032] The brush disc 4 is mounted on a bottom of the body 1 (i.e. the chassis 101).

[0033] The storage tank 8 is secured on the body 1 (i.e. the chassis 101) and is in communication with the brush disc 4, such that after the drive system 2 is operated by a user to control the body 1 to move, the storage tank 8 supplies waters to the brush disc 4 so that the brush disc 4 cleans and washes a ground/floor, and the water absorption rake 3 scraps and absorbs the waters on the ground/floor.

[0034] In another embodiment, the body 100 further includes a lid 12 arranged on a top of the rear end of the chassis 101 and configured to cover and uncover the chassis 101, thus replacing or maintaining the sterilization structure.

[0035] The air inlet 5 is defined on a rear end of the lid 12 and is located above the water absorption rake 3.

[0036] In another embodiment, as shown in FIG. 5, the chassis 101 has a connection tab 103 connected on the rear end of the lid 12 by a rotary shaft 10 so as to uncover and cover the lid 12.

[0037] The sterilization structure 200 is accommodated in the cover 12, is located above the rear end of the chassis 101, faces the drive system 2, and communicates with the air inlet 5.

[0038] The filter 6 is fixed in an air conduit 11 and is located above the sterilization structure 200. In another embodiment, the filter 6 is a High-Efficiency Particulate Air (HEPA) filter.

[0039] The air outlet 7 is defined on a top of the lid 12 and is located above the filter 6.

[0040] The accommodation box 9 is disposed on the body 1 (i.e. the chassis 101) and is in communication with the sterilization structure 200. In another embodiment, the storage tank 8 and the accommodation box 9 are defined between the drive system 2 and the water absorption rake 3. The storage tank 8 includes a detachable cap 801, and the accommodation box 9 includes a removable cover 901. Thereby, the detachable cap 801 is opened so as to supplement the waters into the storage tank 8 after running out of the waters and to cover the storage tank 8 after feeding the new waters. After running out carbon dioxide, the detachable cap 801 is opened so as to supplement the carbon dioxide into the accommodation box 9, and then the removable cover 901 is covered to the accommodation box 9.

[0041] The power supply P is fixed on the body 1 (i.e. the chassis 101) and is electrically connected with the drive system 2 and the sterilization structure 200.

[0042] The body 100 includes the air conduit 11 which communicates with the sterilization structure 200 and the air outlet 7 so as to guide clean airs out of the air outlet 7 via the air conduit 11, thus cleaning airs.

[0043] As shown in FIG. 2, the sterilization structure 200 includes a motor 201, a fan 202, a disinfecting tube 203, a main controller 204 configured to control the motor 201 and the fan 202, a heater controller 205, a delivery pipe 206 configured to deliver chlorine dioxide, a control valve 207, a heating ring 209, a fixer 208 configured to fix the heating ring 209, a stop mesh element 210, an opening 211, and a rotatable spray ring 212.

[0044] The motor 201 is electrically connected with the power supply P. A front end of the fan 202 is connected with the motor 201, and a rear end of the fan 202 is coupled with the disinfecting tube 203. The main controller 204 and the heater controller 205 are mounted on an outer wall of the disinfecting tube 203 and are electrically connected with the power supply P. In another embodiment, as illustrated in FIG. 2, the main controller 204 is mounted on the outer wall of the disinfecting tube 203 opposite to the heater controller 205. The delivery pipe 206 is in communication with the accommodation box 9 and the disinfecting tube 203. The control valve 207 is fixed on a predetermined position of the delivery pipe 206 and is controlled by the heater controller 205 so as to control the carbon dioxide to flow into the disinfecting tube 203. The fixer 208 is secured on an end of the disinfecting tube 203 away from the fan 202, the heating ring 209 is disposed on an end of the fixer 208 away from the disinfecting tube 203, and the stop mesh element 210 is mounted on an outer wall of an end of the heating ring 209 away from the fixer 208. In another embodiment, the stop mesh element 210 has 400 meshes. The central opening 211 is defined on the end of the heating ring 209 away from the fixer 208, and the central opening 211 has a through hole 213 formed on an inner wall thereof. The rotatable spray ring 212 is fixed on an end of the central opening 211 away from the heating ring 209.

[0045] With reference to FIG. 2, the rotatable spray ring 212 has a coupling tube 214 and multiple aerosol nozzles 215. The coupling tube 214 passes through the through hole 213 of the central opening 211 and communicates with the accommodation box 9, and the multiple aerosol nozzles 215 are spaced angularly, face inward, and communicate with the coupling tube 214. The heater controller 205 is turned on or off to control the heating ring 209 to heat up to 100 °C, and the heater controller 205 also controls the control valve 207 so that the multiple aerosol nozzles 215 spray aerosol.

[0046] Referring to FIGS. 3 and 4, in operation, dirty airs flow into the sterilization structure 200 from the air inlet 5, in other words, the dirty airs in which bacteria and virus contain are drawn into the disinfecting tube 203 by the fan 202 and are discharged to the central opening 211. The heating ring 209 heats the stop mesh element 210 to 100 °C so that the stop mesh element 210 heats and stops the bacteria and the virus, thus obtaining disinfection. The multiple aerosol nozzles 215 of the rotatable spray ring 212 spray the carbon dioxide to sterilize the dirty airs, and the HEPA filter 6 filters the dirty airs, thus producing clean airs. Thereafter, the clean airs are discharged out of the air outlet 7 via the air conduit 11, thus eliminating the virus, such as COVID-19, SARS or Influenza.

[0047] While the first embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. The scope of the claims should not be limited by the first embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
