It should be noted that the housing 100 in this embodiment is a waist-shaped cylinder. Specifically, the cross section of the cylinder first decreases and then increases from bottom to top, and the bottom is provided with an air inlet 101, and the top is provided with a Air outlet 102 is arranged. The aromatherapy disc 500 is arranged in the casing 100 near the air outlet 102 , and the first opening is just at the upper edge of the peripheral surface of the casing 100 .

Specifically, the shape of the first opening is composed of two parallel straight lines perpendicular to the upper edge of the peripheral surface of the housing 100 and an arc connecting the two straight lines, and the first opening forms a U-shaped notch on the upper edge of the housing 100 .

A matching first cover 103 is disposed on the first opening, and the first cover 103 can selectively open or close the first opening.

During use, try not to expose the aroma diffuser 500 to the air. On the one hand, it will affect the air flow of the entire air purification system, and on the other hand, exposing the aroma diffuser 500 to the air is not beautiful. For this purpose, a first cover 103 matching the first opening is provided. Opening or closing of the first opening can be realized through the working position state of the first cover body 103 .

Specifically, the first cover 103 can just be fastened on the first opening, so the shape of the first cover 103 is similar to that of the first opening, and there are also two parallel straight lines. It is closed by a line segment of the straight line, and the other end is closed by a circular arc line segment.

It should be noted that the projection of the line segment perpendicular to the two parallel line segments on the plane perpendicular to the vertical direction of the housing 100 on the first cover 103 is also an arc, when the first cover 103 is fastened on the first opening , to close the first opening, the line segment is combined with the upper edge of the peripheral surface of the casing 100 to form a whole, and the entire casing 100 on the first cover 103 becomes a complete one.

Bag.

The positional connection relationship between the first cover 103 and the first opening can be implemented in various ways, specifically, the following two ways can be implemented.

method one:

On the two straight lines of the first opening, holes are respectively provided on the upper edge of the peripheral surface of the housing 100, and the first cover 103 is provided with a protrusion at the position corresponding thereto, and the protrusion can be pivotally connected to the first opening. In the hole above, the first cover 103 can rotate relative to the first opening through the pivot structure, thereby realizing the function of opening or closing the first opening.

Specifically, when the first cover 103 needs to be opened, the first cover 103 is rotated relative to the first opening, and one end of the arc segment of the first cover 103 moves away from the surface of the housing 100, and the first cover 103 leaves the first opening. Upon opening, the first opening is opened.

Method 2:

The two straight lines of the first opening have sliding grooves, and the two straight lines of the first cover 103 can slide on the sliding grooves.

When the first cover 103 is buckled on the first opening, the edge of the first cover 103 fits with the edge of the first opening. When the first cover 103 needs to be removed to expose the first opening, the first cover 103 is slid upwards along the extending direction of the two straight segments, and the first cover 103 is slid out of the first opening, and the first opening is opened.

In this embodiment, the second type of structure is adopted, the edge of the first opening in contact with the first cover 103 is provided with a slide groove for the first cover 103 to slide.

For overall aesthetics, the surface of the housing 100 is relatively smooth, which will have a certain impact on the operation of sliding out the first cover 103 and opening the first opening. In this embodiment, an anti-skid structure is provided on the outer surface of the first cover 103 .

The purpose of the anti-slip structure is to allow the user to apply force to the first cover 103 more conveniently, so that it can slide out of the first opening conveniently. The specific anti-slip structure can be a protruding block. When sliding out the first cover 103, an upward force is applied to the protruding block to slide upwards with the first cover 103; A region with a relatively large roughness is provided on the body 103 to increase the frictional force between the user's force-applying part and the first cover 103 , thereby facilitating the first cover 103 to slide out. Certainly, the anti-slip structure may also be implemented in other forms, and is not limited to the above-mentioned implementation manner.

In this embodiment, the anti-slip structure is a strip-shaped tooth rib provided on the first cover 103 , and the extending direction of the strip-shaped tooth rib is perpendicular to the sliding direction of the first cover 103 .

The function of the bar-shaped teeth is to increase the frictional force between the user's force-applying part and the first cover 103 . Specifically, arrows may also be provided above the bar-shaped tooth ribs, so that users can quickly understand the usage method of this embodiment.

The dust collecting device 300 in this embodiment is arranged annularly along the circumference of the housing 100 , and a purification ball is rotatably arranged inside it, and the surface of the purification ball has a dust suction cavity.

In the air, dust has a great specific gravity. Judging from the physical characteristics of dust, dust is a solid impurity with many irregular shapes. From the perspective of its chemical characteristics, the composition of dust is relatively complex, and it sometimes provides acid radicals and metal ions that cause degradation. Some dust itself is acidic or alkaline, such as sulfuric acid smog and photochemical smog are acidic, and particles such as metal oxides are alkaline. In addition, the floating dust in the dust has a small particle size and a small surface area, so their adsorption capacity is very strong, and they can adsorb harmful substances in the air on their surfaces, so they are acidic or alkaline. Due to the complex physical and chemical properties of dust, it is difficult to use a special filter material to filter it and achieve a good purification effect. The easiest and quickest way to deal with dust is to use other substances to absorb it, thereby reducing the content of dust in the air and achieving the purpose of purification.

The setting of the dust collecting device 300 is to absorb the dust in the air. In actual implementation, in order to increase the adsorption of dust, a purification ball can also be arranged inside the dust collecting net to enhance the adsorption effect. Specifically, adsorption cavities are distributed on the purification ball, which increases the specific surface area of the purification ball and further strengthens the adsorption effect on dust.

The setting of the dust collecting device 300 can absorb the dust in the air before the air is filtered by the filter, so as to reduce the workload of the later filter and achieve a better effect of purifying the air.

Because the dust in the air is very small, the dust collection net adopts the principle of electrostatic adsorption. Electrostatic adsorption is a kind of physical adsorption, and the biggest advantage is that it is reversible. Therefore, the dust collection net in this embodiment can be replaced.

The air enters the housing from the ventilation device 200, and the dust collection device 300 performs preliminary dust adsorption. The dust in the air has a large proportion, and the setting of the dust collection device 300 greatly reduces the filtering burden of the later stage filter. The air then moves upwards along the cylindrical structure of the shell, and passes through the filter device in turn for air filtration.

The filtering device in this embodiment includes an activated carbon filter 401 , a HEPA filter 402 , a colloidal cotton coarse filter 403 , and a nanophotocatalyst filter 404 arranged in sequence from bottom to top.

The active carbon in the active carbon filter screen 401 is a kind of black amorphous granular matter or fine powder. In air purifier products, it generally exists in granular form. Activated carbon particles have a large surface area, and there are abundant micropores all over the body. Its chemical characteristics determine that it has a strong adsorption capacity and can fully contact with the gas, that is, it has a large adsorption capacity and can be easily adsorbed. Harmful gases such as benzene, toluene, xylene and carbon tetrachloride. When these gases are adsorbed by micropores, they play a role in purification.

Usually, the HEPA filter 402 is made of chemical fiber or glass fiber, and a floc structure is used inside. In terms of filtering effect, the effective removal rate of particles with a diameter of 0.3 microns can reach more than 99.74%, and most of the smoke particles produced in the smoking environment are around 0.5 microns. This type of material can also be filtered well , so generally speaking, the HEPA filter 402 has a good effect on PM2.5 filtration.

The coarse filter made of gelatinized cotton can effectively filter the floating dust in the air with a size of more than 20 microns, including the hair of pets at home, dandruff of human body, or pollen and other substances, and the filtering effect can generally reach 92%. about. What's more powerful is that the colloidal cotton also has av-990 dynamic sterilization technology. After it is made into a coarse filter, it can give full play to the role of a large number of av-990 cationic groups contained in its surface. Because the surface of the cell membrane of bacteria and fungi has negative charges, they are neutralized when they meet, so that the breathing mechanism of bacteria can be inhibited and death occurs, and the number of charges is changed to cause bacterial dissolution, so that the efficient removal of bacteria can be achieved. Purpose.

Photocatalysts use sunlight, fluorescent lamps, and ultraviolet light as energy sources to excite electrons (e-) on the valence band to transition to the conduction band, and generate corresponding holes (h+) on the valence band to generate active oxygen and Hydroxyl free radicals can oxidize and decompose formaldehyde, methylamine, benzene, xylene, TVOC and other harmful organic substances, pollutants, odors, bacteria, etc. into harmless CO ₂ and H ₂ O, so as to purify the air and decompose harmful organic substances Purpose.

It should be noted that, in the filter device in this embodiment, the structure of the HEPA filter 402 is distributed along the circumferential direction of the casing 100 in a leaf shape. And activated carbon filter screen 401, colloidal cotton coarse filter screen 403, nano photocatalyst filter screen 404 are all three-dimensional laminated structures with twistable angle filter blades, which can form a spiral passage for air to rise, and the air can pass through the filter screen of this structure more easily. Fully contact with the filter to achieve a better purification effect, and the existence of the spiral channel, the flowing air forms a spiral airflow, which has a better flow rate. The filtered and cleaned air passes through the aromatherapy disc 500 and is discharged from the air outlet 102 with aromatherapy molecules, which can provide aromatherapy atmosphere for the air while cleaning the air.
