Description

Technical Field

[0001] The invention belongs to the technical field of air purification equipment, and in particular relates to a mobile air purifier. Background Art

[0002] In order to provide a comfortable and odorless place in the activity environment, people often use air purifiers to purify large particles and odorous substances in the environment. Among them, large floating particles are mostly directly filtered and blocked by filter cloth, while odorous substances require materials that can absorb odors, such as bamboo charcoal, minerals, active materials, etc. In the past, most air purification equipment was placed in a single position. This method is difficult to meet the needs of rapid air purification in the space environment and spatial transfer of the device. At the same time, in order to improve the purification efficiency, most of the methods used are to directly increase the amount and speed of the sucked air passing through the purification components, that is, to increase the air flow and flow rate. Traditional purification components are relatively constant in size. On the one hand, they have a high air barrier, resulting in an increase in the overall noise of the equipment. On the other hand, when a large amount of air passes through the purification components of a constant volume at a high speed, the purification materials in some areas cannot be fully in contact with the air due to the effect of air pressure, such as areas with large gaps caused by large density and uneven distribution of some fillers, resulting in different air purification quality and aging degrees of purification materials in different areas, which is difficult to meet the needs of air purification.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1: Figure 1-6 As shown, a mobile air purifier includes a host 1, a fan 11 and a control panel. A mounting cavity 12 is opened in the middle of the host 1, the fan 11 is arranged at the bottom of the mounting cavity 12, an air duct 13 connected to the air inlet area of ​​the fan 11 is opened on the side of the host 1, and a filtering mechanism is arranged in the mounting cavity 12;

[0026] The filtering mechanism includes a front filter 2, an air distribution ring 3 and a rear filter assembly. The fan 11 is arranged in the middle of the installation cavity 12. The air distribution ring 3 is connected to the fan 11. The front filter 2 is annular and is arranged in the installation cavity 12 concentrically with the fan 11. The front filter 2 cooperates with the air distribution ring 3 to close the area corresponding to the fan 11 in the installation cavity 12. The rear filter assembly is arranged on the upper side of the air distribution ring 3 and slides to seal and fill the upper area of ​​the installation cavity 12.

[0027] The rear filter assembly includes a filter cartridge 4, a center column 41, an air guide group and a purifier. The filter cartridge 4 is slidably sealed in the installation cavity 12 by means of guide ribs. The filter cartridge 4 is hollow and has a number of air outlets 42 evenly corresponding to the upper and lower ends. The center column 41 is fixed in the filter cartridge 4. The number of air guide groups is consistent with the number of pairs of the corresponding upper and lower air outlets 42 and corresponds one to one. The purifier is arranged in the air guide group.

[0028] When installing the filter mechanism into the main unit 1, the front filter 2 and the filter cartridge 4 are installed in sequence from bottom to top, so that the air sucked from the air duct 13 on the side of the main unit 1 must pass through the front filter 2 and the filter cartridge 4 before it can be discharged, wherein the front filter 2 is made of filter cotton material, which is used to filter large particles such as dust impurities at the front end, and the purifier in the rear filter assembly is made of fillers such as natural mineral powder, natural active materials, bamboo charcoal, etc., which is used to absorb and decompose formaldehyde, carbon monoxide, and odor;

[0029] When external air is drawn into the main unit 1 through the fan 11, due to the setting of the filter cartridge 4 of the rear filter assembly and the setting of multiple air guide groups, the air must pass through the multiple purifiers in the air guide group from bottom to top before it can be discharged. This can produce a strong exhaust directionality for the air flow, and because the air must pass through the purifiers in the air guide group from bottom to top before it can be discharged, and each air guide group is independent, so under the air diversion of the air diversion ring 3, the neutralization attenuation degree and aging degree of the purifier in each air guide group can be ensured to be consistent as much as possible, thereby improving the utilization rate of the filter material and the purification adequacy.

[0030] The air guide group is composed of two spiral air guide blades 43 . The two spiral air guide blades 43 correspond to the two side edges of the corresponding air outlet 42 one by one. The spiral air guide blades 43 are sealedly connected to the center column 41 and the inner wall of the filter cartridge 4 .

[0031] The purifier is composed of a plurality of hollow plates 44 filled with purification materials. The plurality of hollow plates 44 of the same purifier match the spiral extension direction of the spiral air guide blades 43. The purifier closes the interval between two spiral air guide blades 43 of the same air guide group.

[0032] The structure of the spiral guide blades 43 can increase the time and path distance required for air flow to a greater extent within a certain unit height, thereby more fully reacting and neutralizing with the purifier, and the purified matter filled in the hollow plate 44 can react and purify the air more effectively.

[0033] A plurality of air inlet holes 7 are provided in the area corresponding to the main unit 1 and the air duct 13 ; this can block some larger objects and impurities on the outside of the main unit 1 to avoid blockage of the air duct 13 .

[0034] A blocking net is provided at the air outlet 42 at the upper end of the filter cartridge 4, so as to prevent external impurities from falling in.

[0035] Example 2: Figure 2-6 As shown, it is a further improvement on the basis of Example 1, a regulating motor 5 is further provided between the air distribution ring 3 and the filter cartridge 4. When the regulating motor 5 is provided, the middle column 41 and the filter cartridge 4 are rotationally sealed, one of the spiral guide blades 43 in the same air guide group is fixedly connected to the filter cartridge 4 and is slidingly sealed to the inner wall of the filter cartridge 4, the other spiral guide blade 43 is fixedly connected to the filter cartridge 4 and is slidingly sealed to the middle column 41, the end end of the spiral guide blade 43 connected to the middle column 41 is also provided with a shielding fan 6 which is slidingly sealed to the inner wall of the filter cartridge 4 and matches the shape of the corresponding air outlet 42, the regulating motor 5 is arranged at the upper end of the air distribution ring 3 and the output shaft is connected to a transmission head 51, the lower side of the middle column 41 rotates through the lower end of the filter cartridge 4 and is provided with an interlocking groove 52 matching the transmission head 51.

[0036] When a regulating motor 5 is provided, multiple hollow plates 44 of the same purifier are slidingly and sealingly connected to each other, the plane projection of the hollow plates 44 is fan-shaped, and the uppermost and lowermost layers of the multiple overlapping hollow plates 44 are respectively connected to two spiral guide blades 43.

[0037] Furthermore, in order to meet the change of the blowing wind force of the fan 11, adapt to the discharge of purified air and reduce the air disturbance conflict between the exhaust and the intake air, when installing the filter cartridge 4, the engaging groove 52 at the lower end of the filter cartridge 4 is aligned with the transmission head 51 at the upper end of the air distribution ring 3, so that the regulating motor 5 can control the rotation of the middle column 41 through the transmission head 51. Since the relative position of the filter cartridge 4 itself cannot rotate, the rotation of the middle column 41 can drive the correspondingly connected spiral guide blades to rotate, and change the interval between the two spiral guide blades in the same group. That is, under the premise that the current air input flow rate is constant, the maximum flow rate increases when the channel becomes smaller. When the flow rate is reduced, the flow rate is increased. On the contrary, when the flow rate is increased, the maximum flow rate is increased and the flow rate is reduced. In this way, when the fan 11 is running at a high flow rate, the flow rate can be reduced by increasing the interval, which can improve the reaction time between the air and the filter medium on the one hand, and reduce the noise generated when the air flows on the other hand. On the contrary, when the fan 11 is running at a low flow rate, the air flow can be accelerated to achieve a strong exhaust effect. At the same time, the point control motor 5 adjusts the interval distance of the spiral guide blades 43 synchronously with the operating power of the fan 11, that is, it always maintains a relatively comprehensive state, thereby ensuring effective filtration while reducing environmental noise;

[0038] Furthermore, since the multiple hollow plates 44 overlap up and down and are slidably sealed and connected to each other, when the interval between the two spiral air guide blades 43 in the same group changes, the multiple hollow plates 44 of the same purifier will overlap and shield or unfold each other. When shielding, the resistance to air is increased, that is, in the state of small channel and high air flow rate, it can force to increase the reaction time between air and filter medium and reduce the air flow rate; when unfolding, it can reduce the obstruction to air and increase the area corresponding to the air in the space under the state of slow air flow, so as to achieve the purpose of flexible regulation and correspondence. Compared with the conventional single-area filtration or upright and plate filtration methods, the filtration effect is more efficient, avoiding the situation that the air only passes through a single area and the filtration effect of the area is reduced and the circulation speed is low.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
