Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and particularly relates to an air purification box. Background Art

[0002] With the improvement of living standards, people have higher requirements for the living environment. To meet the needs of urban life and cope with pollution and smog, various air purifier products have emerged. Currently, all air purifiers on the market are mechanical and electronic. Its principle is to make indoor air flow through the filter in the air purifier through a fan and then flow out after physical or chemical filtration to achieve the purpose of purifying the air. This type of air purifier belongs to the category of household appliances, with a relatively high price and a relatively low lifespan of the core components (such as filters). Some have poor air purification effects, and some even cause other pollution.

[0003] In addition to using the above-mentioned electrical air purifiers, people also often filter or purify the air by placing plants such as potted plants indoors. Biological purification mainly utilizes the biomass adsorption and filtration function of the plants themselves and the function of plants releasing oxygen and absorbing carbon dioxide during photosynthesis. It is a relatively safe air purification method, and it is simple to operate and has a low cost. However, the disadvantage of using plants for biological purification is that plants can only perform respiration at night and cannot perform photosynthesis, which will compete with people indoors for oxygen. Although some technologies have proposed irradiating plants at night to solve this problem, these technologies still cannot solve the problems of effective utilization of light sources and good shielding at night. Summary of the Invention

[0004] To solve the above problems, the present invention proposes an air purification box, which can allow plants to perform stable photosynthesis for 24 hours, provide oxygen for the room, avoid competing with people for oxygen at night, and at the same time solve the problems of effective utilization of light sources and good shielding at night through an automated photosensitive design and opening and closing control.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will describe the exemplary embodiments of the present disclosure in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0025] Embodiment 1

[0026] See Figure 1 , Figure 1An air purification box according to Embodiment 1 of the present invention includes a light-shielding cover 1, a plant 2, and a light-emitting body 3. The periphery and top surface of the light-shielding cover 1 are closed. The plant 2 and the light-emitting body 3 are arranged inside the light-shielding cover 1. The periphery and / or top surface of the light-shielding cover are provided with air holes. The light-emitting body 3 is an LED light source or a fluorescent substance that meets the photosynthesis requirements of plants. The inner surface of the light-shielding cover 1 is wholly or partially set as a mirror surface, and the periphery and / or top surface of the light-shielding cover are set as a structure that can be opened and closed. In addition, the air purification box further includes a base 4, and both the light-shielding cover 1 and the plant 2 are arranged on the base 4.

[0027] After the night light-emitting system is introduced into the air purification box of the present invention, it can guide the plant to perform stable photosynthesis for 24 hours, avoiding competing with people for oxygen at night. The mirror surface design of the light-shielding cover improves the lighting effect.

[0028] To achieve a good opening and closing effect of the light-shielding cover 1, the light-shielding cover 1 is of a square structure, including four vertical panels 5 on the periphery and one horizontal panel 6 on the top. To achieve a good night lighting effect, in this embodiment, the four vertical panels 5 on the periphery, one horizontal panel 6 on the top, and the base 4 are all designed as mirror surfaces.

[0029] As a way to achieve opening and closing, at least one of the vertical panel 5 and the horizontal panel 6 includes two sub-panels. The two sub-panels are driven by an electric push rod 7 to open or close the light-shielding cover 1 in a rotatable and foldable manner. Here, taking the horizontal panel 6 as an example, see Figure 1 , each sub-panel includes a retractable part 8 and a folding part 9. The retractable part 8 is driven by a retractable motor 10 and a retractable transmission member to unfold and retract on the folding part 9, and the folding part 9 is driven by the electric push rod 7 to rotate and fold.

[0030] In the present invention, the opening and closing of the light-shielding cover are automatically controlled according to the detection of natural light. Specifically, the air purification box of the present invention further includes a light sensor 11 and a microprocessor 12 communicatively connected thereto. The light sensor 11 is arranged outside the light-shielding cover 1 for detecting natural light and transmitting the detection signal to the microprocessor 12. The microprocessor 12 is communicatively connected to the drive circuits of the retractable motor 10 and the electric push rod 7, and is used to automatically control the opening and closing of the light-shielding cover 1 according to the signal of the light sensor 11.

[0031] See Figure 3 , Figure 3The process of the lateral panel 6 being opened is shown. The light sensor 11 converts the detected external natural light intensity signal into an electrical signal and transmits it to the microprocessor 12. The microprocessor 12 is pre-programmed with a comparison program. When it is determined that the external natural light intensity reaches the set value, the microprocessor 12 issues a control instruction to control the operation of the retracting and extending motor 10, driving the retracting and extending part 8 to retract on the folding part 9. At the same time, or during this period or after this, the working rod of the electric push rod 7 starts to retract, driving the folding part 9 to open inward, thereby completing the opening operation of the light shield. When the light sensor 11 and the microprocessor 12 detect that the external natural light intensity starts to be lower than the set value, although not shown in the figure, it is easy to understand that, according to the opposite actions to the above, the closing operation of the light shield is completed.

[0032] It should be noted here that when the light-emitting body 3 of the present invention is powered by a power supply, for example, an LED light source, its circuit should be communicatively connected to the microprocessor 12 and controlled by the microprocessor 12. In this way, when the light shield is opened, the plants can already use natural light for photosynthesis, and the light-emitting body 3 can be turned off to save energy. On the contrary, when the light shield is closed, the light-emitting body 3 lights up accordingly.

[0033] In this embodiment, the vertical panel 5 on the sunny side can also be automatically opened and closed. Figure 1 It is set that the sunny side is the right side. Figure 2 is Figure 1 the right side view. In this embodiment, the light sensor 11 is also arranged on the sunny side.

[0034] Through the automated photosensitive design and opening / closing control of the present invention, the light shield is opened during the day for plants to use natural light and closed only at night, solving the problems of good shielding at night and effective utilization of light sources.

[0035] As Figure 1 shown, a blower 13 is also arranged in the air purification box. The microprocessor 12 is communicatively connected to the drive circuit of the blower 13 and can operate according to the set time to accelerate the gas exchange between indoors and outdoors. The air holes include an intake hole 14 and an exhaust hole 15. After the blower 13 is started, the outdoor gas is mainly inhaled from the intake hole 14, and the oxygen-rich gas generated by the plants is mainly discharged from the exhaust hole 15. As Figure 1 and Figure 2 shown, as an important improvement, filter devices are arranged in the exhaust holes 15 of the present invention, which can filter out large particles or harmful substances discharged from the air purification box, further improving the quality of the output oxygen-rich gas.

[0036] As shown in the figure, a nozzle 16 is also provided in the air purification box, and the nozzle 16 is connected to a water tank 17 through a water pipe, and the water pipe and the water tank 17 are connected through an electric control valve 18. In the present invention, the watering of plants can also be performed automatically, specifically, relying on a humidity sensor 19 provided in the planting pot of the plant 2 or at the bottom of the planting pot to detect the humidity of the soil or the planting pot body and transmit the detection signal to the microprocessor 12, and the microprocessor 12 is communicatively connected with the control circuit of the electric control valve 18, and is used to automatically control the nozzle 16 to spray water on the plant 2 according to the signal of the humidity sensor 19 and after comparison with the standard value.

[0037] As an air purification device for household or indoor use, the placement of the device should be optional and should not be limited by the location of the building power supply. For this reason, the outer surface of the air purification box of the present invention is provided with a solar photovoltaic panel 20 facing the positive side, and the solar photovoltaic panel 20 is connected to the battery 21, so that electricity can be generated by the solar photovoltaic panel 20, and stored by the battery 21 for use by the entire device, without relying on an external power supply, and also saving electricity. Of course, this is not a limitation of the present invention, and the present invention can also be provided with an external power supply access port to power the entire device or charge the battery 21 when needed.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
