[0029] like Figures 1 to 6 As shown, a vertical air purification device for improving the air quality of a common home environment specifically includes an air purification device housing, purification equipment, a fan assembly, and a control and display system assembly.

[0030] The housing of the air purification device includes an air inlet panel 5 , an air inlet side cavity 6 , an air outlet side cavity 7 , a front panel 3 , and an air outlet member 1 .

[0031] The air inlet panel 5 is located on the back of the purification device. A number of inwardly bent flanges are arranged on the upper side of the air inlet panel 5, and the flanges inserted into the inner side of the air outlet member 1 can limit the upper side of the air inlet panel 5 from falling outward. Studs for installing metal plates are arranged on the lower side of the air inlet panel 5, and the metal plates can be attracted by the magnetic suction device embedded in the air inlet side cavity 6. The air inlet panel 5 is provided with air inlets 8 arranged in a certain regular pattern, and the air inlets 8 can be in the shape of a long grille, an ellipse, or an oblong. The air inlets 8 are not limited to the form described above, and can be equidistant in a certain regular arrangement. The arrangement in a certain regular pattern is not limited to the equidistant style, and the arrangement must cover the area of ​​the air inlet cross-sectional area of ​​the purification section configured by the corresponding air inlet side cavity 6.

[0032] A layer of nylon mesh with a certain mesh size is bonded to the inner side of the air inlet panel 5 by a hot pressing process. A jacking device 11 that can trigger a safety switch is provided on the upper side of the air inlet 8 area of ​​the air inlet panel 5. The jacking device 11 can trigger the safety switch to power on the purification device when the air inlet panel 5 is in a closed state. The jacking device 11 does not trigger the safety switch after the air inlet panel 5 is opened. Furthermore, even when the purification equipment is connected to an external power supply and the safety switch is not triggered, it is in a power-off protection state. The power-off protection state can ensure the safety of maintenance personnel. The air inlet side cavity 6 and the air outlet side cavity 7 are integrally formed by injection molding using the same mold. After the air outlet side part 7 is injection molded by a mold, the side ventilation holes 16 need to be further cut.

[0033] Figure 7 It is a cross-sectional view showing the mold-jointing structure of a vertical air purification device according to an embodiment of the utility model.

[0034] like Figure 7 As shown, the mirror assembly of the air inlet side cavity 6 and the air outlet side cavity 7 can be constructed into a structure with a single air inlet and a top air outlet. The air inlet side cavity 6 and the air outlet side cavity 7 are connected at the outer side edge joint below the handle structure 2 by a segmented cross-convex and concave combination structure of the inner and outer edges. The mirror assembly of the air inlet side cavity 6 and the air outlet side cavity 7 mainly relies on the screws set in the purification section sinking structure. The air inlet side cavity 6 includes the raised support foot 4, the cavity bottom section structure, the cavity middle section structure, the cavity upper section structure, and the cavity upper air outlet structure in order from bottom to top. The raised support foot 4 is a thin shell structure, and the demoulding direction of the raised support foot 4 is consistent with the cavity part. The cavity bottom section structure includes a magnetic suction device installation structure 25 that attracts the metal plate of the air inlet panel 5 and a power line through hole structure. The magnetic suction device installation structure 25 is embedded in the square grooves on the left and right sides of the cavity bottom section structure.

[0035] The power cord through-hole structure is located in the middle of the bottom section of the cavity structure. The power cord through-hole structure adopts an S-shaped movement structure 24. The S-shaped movement structure 24 can constrain the power cord to freely enter and exit the through-hole. The middle section structure of the cavity includes a middle filter element placement structure and a side air duct structure 22. The middle filter element placement structure forms a rectangular closed channel matching the cross-sectional area of ​​the filter element from the middle position of the middle section of the air inlet side cavity 6.

[0036] Furthermore, the side air duct structure 22 is a closed channel structure formed by the two side walls of the middle filter element placement structure and the two outer thin shells of the inlet and outlet side cavities 6 and 7. The side air duct structure 22 is connected to the cavity bottom section structure. The side air duct structure 22 needs to be placed with a bottom wind shielding foam plate 23 near the cavity bottom section structure. The upper section structure of the cavity is provided with a fan body 10 installation structure, a purification equipment circuit board 20 installation structure, and an electrostatic filter element power drive 19 installation structure.

[0037] The air outlet structure setting on the cavity matches the air outlet position of the fan body 10, and the front panel 3 is consistent with the installation structure setting of the purification equipment air inlet panel 5. The front panel 3 is not provided with an air outlet and a ejector device 11 for triggering a safety switch. The front panel 3 also adopts an upper flange limiter and a lower magnetic closure. The air outlet 1 is installed on the upper part of the purification device. The air outlet 1 includes a purification equipment control and display panel 18 installation structure, an oblique air outlet structure 26, and a connection structure between the air outlet 1 and the inlet and outlet side cavity parts 6 and 7. The installation structure of the control and display panel 27 of the purification equipment is set into an inclined panel structure at a certain angle for the convenience of visual observation. The control and display panel 18 of the purification equipment is installed at the lower part of the inclined panel structure. The inclined air outlet structure 26 is set according to the setting angle of the control and display panel 27. The inclined air outlet structure 26 is composed of thin-walled grilles of equal thickness. The extension height of the thin-walled grilles of equal thickness is proportionally reduced from the highest height of the inclined surface of the installation structure of the control and display panel 18 to the plane height of the air outlet member 1. The air outlet member 1 is connected to the studs on the upper part of the outer side of the inlet and outlet side cavities by screws. The installation structure of the air outlet member 1 also has a certain limiting and closing effect on the upper side of the structure surrounded by the inlet and outlet side cavities 6 and 7.

[0038] The purification equipment includes a pre-filter 13, an electrostatic filter 15 filter element, a high-efficiency filter 12, and a deodorizing filter 14. The pre-filter 13 performs primary filtration by inserting filter cotton into the grille. The electrostatic filter element 15 includes a discharge section and a purification section. The discharge section is located in front of the purification section. The discharge section is a group of metal-processed spikes arranged at a certain distance at a specific cross-sectional position on the front side of the filter element. The spike group is arranged with equidistant spikes arranged at a certain distance. The equidistant spikes can generate corona when driven by a high-voltage electrostatic drive power supply 19. The certain distances of the horizontal and vertical arrangements of the spikes are determined according to the range of the corona generated. The corona range can ensure that the entire cross-section of the filter element through which the airflow passes is covered. A certain distance cannot be lower than a specific limit value. If it is lower than a specific limit value, it will cause a hidden danger of high-voltage discharge. The particles in the air will be charged after passing through the corona section. The purification section includes a high-voltage potential section and a zero-voltage potential section. The high-voltage potential section is connected to the spike group by an aluminum tube row and driven by an electrostatic drive power supply 19. The high-voltage potential section and the zero-voltage potential section are equidistantly arranged in an interlaced manner. A potential difference is formed between the high-voltage potential section and the zero-voltage potential section. After the charged particles pass through the potential difference area, the flow direction will be offset. Further, the particles will be captured in the purification section. The filtration level of the high-efficiency filter 12 can reach the high-efficiency level of the relevant national standards. The high-efficiency filter 12 is configured behind the electrostatic filter 15. The high-efficiency filter 12 is configured behind the electrostatic filter 15 to have an optimization effect. The charged particles may not be captured in the purification section of the electrostatic filter 15 due to the influence of wind speed. Further, the charged particles continue to migrate to the rear filter element section. The charged particles are more likely to be actively adsorbed by the electrostatic attraction of the microscopic level of the filter element of the high-efficiency filter 12.

[0039] The deodorizing filter 14 is made of honeycomb filled with activated carbon particles, and the deodorizing filter 14 can absorb gaseous pollutants such as formaldehyde and TVOC commonly used in home environments.

[0040] The ultraviolet purification section is an optional configuration of the purification equipment. The ultraviolet purification section includes an ultraviolet lamp mounting bracket 17 and an ultraviolet device assembly. The ultraviolet device assembly mounting bracket 17 is made of sheet metal and bent and fixed to the bottom side of the air outlet side cavity 7. Furthermore, ultraviolet light can act on the side duct structure 22 through which the clean air purified by the purification equipment flows.

[0041] The fan assembly includes a fan mounting bracket 9, and the fan assembly includes a fan mounting bracket 9, which is connected to the studs on the inner side of the upper cavity structure of the air outlet side cavity 7 by bending sheet metal. The fan assembly includes a fan body 10, a starting capacitor, and a transformer. The fan body 10 adopts a volute double-inlet centrifugal fan. The control and display system components include a purification equipment circuit board 20, a control and display panel 18, and an electrostatic filter element drive power supply 19. The purification equipment circuit board 20 and the high-voltage electric field drive power supply 19 are installed in the closed space structure of the air inlet side cavity 6 and the air outlet side cavity 7.

[0042] The control and display panel 18 is installed on the inner side of the air outlet 1 of the purification equipment. The control and display panel 18 includes the control system logic and display system. The control system mainly includes the power on and off of the purification equipment, the wind speed gear adjustment of the purification equipment, the intelligent mode switching, the sleep mode switching, and the filter element aging recovery. The above control can be realized through the touch buttons configured on the control and display panel 27. When the power of the purification equipment is started, the equipment immediately enters the default working state of the power on. The default working state of the power on means that the purification equipment operates in the second gear wind speed mode and supplies power to the high-voltage electrostatic filter 15 filter element module, ultraviolet and other purification means. The intelligent mode means that the equipment will adjust the wind speed of the machine according to the indoor pollution degree monitored by the pollution monitoring sensor 21 of the equipment body. The higher the pollution degree, the greater the wind speed of the purification equipment so as to quickly achieve the purpose of indoor purification. The pollution monitoring sensor 21 is installed on the upper side of the air outlet of the air inlet side cavity 6 near the air inlet panel 5. The sleep mode means that the equipment runs at a low wind speed of the first gear and the control and display panel 27 will enter a dimmed brightness state. Furthermore, the status will not affect the nighttime sleep of indoor personnel. Filter element age recovery means that the status display after the filter element is replaced needs to be restored here to restore the accumulation of filter element usage time. The display system mainly controls and displays the content displayed on the panel 27, including the wind speed gear of the purification equipment, the operation mode of the purification equipment, the indoor pollution level monitored by the purification equipment, the filter element usage status and other contents. The filter element usage status indicates the time the filter element has been used. When the filter element usage status reaches the limit, the panel filter element age will issue a warning.

[0043] The vertical air purification device according to the embodiment of the utility model fully combines the characteristics of the air inlet and outlet of the volute double-inlet centrifugal fan, through the ingenious design of the upper and lower clamping structures, and in the case of universal molds, constructs a purification device that takes in air from the back air port, and after purification by the purification section, the air flows into the double air inlet channels on both sides of the volute fan through the closed air ducts on both sides of the clamping structure, and then is discharged from the upper air outlet of the purification device along with the centrifugal fan impeller. The exhaust port is designed to be a slightly forward-inclined air supply structure, which can effectively avoid ineffective circulation purification of the clean air flow, and further improve the efficiency of the purification equipment. In addition, the purification section is equipped with high-voltage electrostatic and high-efficiency filter combined purification to achieve a synergistic purification effect.
