Description

Technical Field

[0001] This invention relates to the field of plant cultivation equipment technology, specifically to a plant growth auxiliary device with air circulation and sterilization function. Background Technology

[0002] In modern agriculture, especially facility agriculture (such as greenhouses, plant factories, seedling boxes, and planting racks), the air quality of the plant growth environment directly affects plant health and yield. In enclosed or semi-enclosed planting environments, poor air circulation can easily lead to excessive humidity and the growth of pathogenic microorganisms (such as fungal spores, bacteria, and viruses), which can then cause plant diseases, resulting in reduced yields or even crop failure.

[0003] Currently, common disease control methods in planting environments mainly include chemical spraying, ventilation, ultraviolet irradiation, and ozone disinfection. Among these, chemical agents pose a problem of pesticide residues, affecting the safety of agricultural products and the ecological environment; while ultraviolet irradiation alone can kill bacteria, it is limited by the inherent property of linear propagation, resulting in blind spots and poor penetration; ozone disinfection has problems such as damaging plants when the concentration is high and slow disinfection speed.

[0004] Most plant growth aids currently on the market use a single fan for ventilation, which has the following technical drawbacks:

[0005] Ordinary circulating fans can only promote air circulation and cannot effectively kill pathogens (such as gray mold and Fusarium) in enclosed or semi-enclosed planting spaces. To achieve sterilization, additional ultraviolet disinfection equipment needs to be purchased, which results in a large space occupation, increased costs, and messy wiring.

[0006] Traditional fans cannot remove suspended particulate matter, odors (such as ammonia and hydrogen sulfide from fertilizers), and static electricity from the air. Some existing devices simply integrate ion generators but lack a systematic air optimization and circulation duct, resulting in sterilization, purification, and circulation not being able to work together effectively.

[0007] Ozone and UV leakage risks: Some devices containing UV lamps do not have adequate physical isolation structures, posing a risk of UV leakage causing burns or excessive ozone release. Summary of the Invention

[0008] In view of the shortcomings of the prior art, the purpose of this invention is to provide a plant growth auxiliary device with air circulation and sterilization function, so as to solve the problems of inefficient sterilization, poor air quality improvement and complex structure in the prior art.

[0009] To solve the above-mentioned technical problems, the present invention is implemented through the following solution:

[0010] A plant growth assist device of the present invention includes:

[0011] The housing includes a front housing and a rear housing, wherein the rear housing is detachably installed on the front housing to form a duct channel;

[0012] The first fan assembly, located at both ends of the housing, is used to form an air circulation;

[0013] The second fan assembly is installed inside the housing and disposed between the first fan assembly. When the second fan assembly and the first fan assembly are working, they create a negative pressure to circulate the air between the housing and the planting environment.

[0014] A light-emitting component, installed inside the housing, is used to sterilize the air circulating in the first fan assembly, the second fan assembly, and the air duct channel;

[0015] A plasma generator is located inside the housing and is used to generate plasma that is discharged from the housing via air circulation.

[0016] Furthermore, the first fan assembly includes a fan cover, an air-concentrating cover disposed within the fan cover, and a first fan body. The fan cover is provided with a first air inlet and a second air outlet disposed opposite to each other for air circulation. The fan cover is connected to the air duct channel to form an air circulation channel.

[0017] Furthermore, a second air inlet is provided next to the first air outlet, and a second air outlet is provided next to the first air inlet. The second air inlet and the second air outlet are used to circulate and discharge the air after the light-emitting component has been sterilized out of the housing.

[0018] Furthermore, the second fan assembly includes an air outlet cover with a third air outlet and a second fan body. The second fan body is installed inside the housing, and the air outlet cover is installed on the housing opposite to the second fan body to circulate air through the third air outlet.

[0019] Furthermore, the plasma generator is installed next to the second fan body to discharge plasma along with the sterilizing air from the housing.

[0020] Furthermore, the light-emitting component includes at least two UVC germicidal lamps arranged side by side, with the second fan body and the plasma generator disposed between them, and the UVC germicidal lamps are used to sterilize the air circulated between the first fan body and the second fan body.

[0021] Furthermore, the inner side of the housing irradiated by the UVC germicidal lamp tube is provided with a photocatalytic coating. When the photocatalytic coating is irradiated by UVC light, it reacts with the UVC light to decompose organic pollutants in the air.

[0022] Furthermore, the tube body of the UVC germicidal lamp is made of quartz glass.

[0023] Furthermore, a controller is provided inside the housing, and a fan knob, a light-emitting knob, and a plasma knob are provided on the rear housing. The controller is used to control the operation of the first fan assembly, the second fan assembly, the light-emitting assembly, and the plasma generator through the control signals of the fan knob, the light-emitting knob, and the plasma knob.

[0024] Furthermore, the housing is provided with a mounting groove for mounting the plant growth aid device on an external device.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] The first fan assembly creates negative pressure inside the housing, which circulates the air in the planting environment and promotes airflow.

[0027] Furthermore, by utilizing the forced convection of the first and second fan components, air containing pathogens is continuously drawn into the duct channel to receive strong doses of light from the light-emitting components, which significantly improves the sterilization coverage and efficiency, and effectively reduces the incidence of plant diseases.

[0028] The plasma released by the plasma generator is discharged with the airflow. The plasma is used to neutralize positively charged particulate matter in the planting environment, settle dust, remove odors and decompose bacteria, effectively improving air quality.

[0029] It integrates air circulation, sterilization, dust reduction and deodorization, eliminating the need to set up multiple independent machines in a limited planting space, thus greatly improving space utilization. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention. Obviously, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] Example 1: As Figure 1-4 As shown, the specific structure of the present invention is as follows:

[0038] A plant growth aid device with air circulation and sterilization function includes:

[0039] The housing 1 includes a front housing 10 and a rear housing 11, with the rear housing 11 being detachably installed on the front housing 10 to form a duct channel;

[0040] The first fan assembly 2, located at both ends of the housing 1, is used to form an air circulation;

[0041] The second fan assembly 4 is installed inside the housing 1 between the first fan assembly 2. When the second fan assembly 4 and the first fan assembly 2 are working, they create a negative pressure to circulate the air between the housing 1 and the planting environment.

[0042] The light-emitting component 3 is installed inside the housing 1 and is used to sterilize the air circulating in the first fan assembly 2, the second fan assembly 4 and the air duct channel;

[0043] Plasma generator 5 is located inside housing 1 and is used to generate negative oxygen ions that are discharged from housing 1 through air circulation.

[0044] In this embodiment, negative pressure is created by the two first fan assemblies 2 at both ends of the housing 1, circulating the air in the planting environment and achieving rapid air circulation. During air circulation, the light-emitting component 3 disinfects and sterilizes the air in the air duct. The UVC germicidal lamp emits short-wave ultraviolet light with a wavelength of 200nm-275nm, preferably 253.7nm. Simultaneously, the housing 1 provides protection, forming a protective shield for the light-emitting component 3, i.e., the UVC germicidal lamp, confining the UVC light inside the ventilation duct and preventing ultraviolet radiation to the planting area or human body, ensuring that the UVC light does not leak out and guaranteeing safe use. The plasma generator 5 is located near the air outlet of the middle second fan assembly 4. The plasma it releases is discharged with the airflow, neutralizing positively charged particles in the planting environment, settling dust, removing odors, and decomposing bacteria, thus improving air quality. The negative pressure created by the first fan assembly 2 and the second fan assembly 4 discharges the disinfected and sterilized air and negative oxygen ions from the housing 1. The added second fan increases the air circulation rate, facilitating air exchange in the planting environment.

[0045] In this embodiment, the rear shell 11 can be rotated 90 degrees on the front shell 10, making it convenient for the user to replace the light-emitting component 3 inside the shell 1, i.e., the UVC germicidal lamp tube. The front shell 10 and the rear shell 11 can be connected by snap-fit ​​or bolts, etc.

[0046] In this embodiment, the first fan assembly 2 includes a fan cover 20, an air-concentrating cover 21 disposed within the fan cover 20, and a first fan body 22. The fan cover 20 has a first air inlet 201 and a second air outlet 24 disposed opposite each other for air circulation. The fan cover 20 is connected to the air duct channel to form an air circulation channel. The first fan body 22 can be a 12038 fan. The air-concentrating cover 21 can increase the airflow rate of the circulating air to the first fan body 22. Air circulation occurs through the first air inlet 201 and the second air outlet 24. The part of the fan cover 20 facing the first air inlet 201 and the second air outlet 24 can be set as a mesh or a filter component to prevent impurities in the air from clogging the air outlet inside the fan cover 20.

[0047] In this embodiment, a second air inlet 23 is provided next to the first air outlet 200, and a second air outlet 24 is provided next to the first air inlet 201. The second air inlet 23 and the second air outlet 24 are used to circulate the air after sterilization of the light-emitting components 3 and discharge the sterilized air out of the housing. Two sets of the first air outlet 200 and the first air inlet 201 are provided, and preferably two sets of the second air inlet 23 and the second air outlet 24 are provided, forming a duct channel for air circulation of multiple light-emitting components 3, thereby enhancing the air circulation.

[0048] In this embodiment, the second fan assembly 4 includes an air outlet shroud 40 with a third air outlet 400 and a second fan body 41. The second fan body 41 is installed inside the housing 1, and the air outlet shroud 40 is installed on the housing 1 opposite to the second fan body 41 to circulate air through the third air outlet 400. The second fan body 41 is preferably a 6025 fan. Due to the arrangement of the first fan body 22 and the second fan body 41, an airflow channel from the first air inlet 201 to the third air outlet 400 and an airflow channel from the second air inlet 23 to the third air outlet 400 can be formed inside the housing 1, realizing a straight or zigzag airflow channel, and realizing the integrated operation of "flowing, sterilizing and purifying at the same time" under forced air circulation.

[0049] In this embodiment, the plasma generator 5 is installed next to the second fan body 41 to discharge plasma along with the sterilized air from the housing 1. The plasma generator 5 can also be a negative ion generator, which generates plasma or negative oxygen ions that are discharged with clean air. This effectively adsorbs odors and suspended particles generated in the planting space due to fertilization and substrate fermentation, keeping the air fresh and enhancing the photosynthetic efficiency of the leaves.

[0050] In this embodiment, the light-emitting component 3 includes at least two UVC germicidal lamps arranged side by side, with the second fan body 41 and the plasma generator 5 positioned between them. The UVC germicidal lamps are used to sterilize the air circulating between the first fan body 22 and the second fan body 41. The UVC germicidal lamps are arranged inside the air duct channel to irradiate the air flowing through the air duct channel and the blades of the second fan body 41 for sterilization and disinfection. The UVC germicidal lamps are designed with strict light isolation to eliminate the risk of UVC ultraviolet leakage and burns, and to avoid the generation of excessive ozone, making them suitable for long-term unattended operation in homes, laboratories, and factory seedling workshops.

[0051] In this embodiment, a photocatalytic coating is provided on the inner side of the housing 1 irradiated by the UVC germicidal lamp. When the photocatalytic coating is irradiated by UVC light, it reacts with the UVC light to decompose organic pollutants in the air. The photocatalytic coating is preferably a nano-titanium dioxide (TiO2) photocatalytic coating, which generates highly oxidizing hydroxyl radicals under UVC ultraviolet irradiation to decompose organic pollutants in the air and perform sterilization. If the UVC germicidal lamp irradiates the inner side of the front housing 10, then the inner side of the front housing 10 has a photocatalytic coating; if the UVC germicidal lamp irradiates the inner side of the rear housing 11, then the inner side of the rear housing 11 has a photocatalytic coating. The photocatalytic coating ensures that UVC ultraviolet light is reflected only within the closed sterilization chamber and does not leak into the planting area, achieving safe sterilization under the condition of "coexistence of humans and plants".

[0052] In this embodiment, the UVC germicidal lamp tube is made of quartz glass material that does not contain the 185nm wavelength, or the UVC germicidal lamp tube is configured to emit UVC wavelength light to avoid generating excessively high concentrations of ozone in the environment and to ensure plant safety. Considering the physiological characteristics of plants' sensitivity to ozone, UVC lamp beads or tubes of specific wavelengths are selected to avoid oxidative damage to plant leaves caused by high concentrations of ozone while sterilizing.

[0053] In this embodiment, a controller is provided inside the housing 1, and a fan knob 110, a light-emitting knob 111, and a plasma knob 112 are provided on the rear housing 11. The controller is used to control the operation of the first fan assembly 2, the second fan assembly 4, the light-emitting assembly 3, and the plasma generator 5 through the control signals of the fan knob 110, the light-emitting knob 111, and the plasma knob 112. The fan knob 110, the light-emitting knob 111, and the plasma knob 112 are respectively connected to the first fan body 22, the second fan body 41, the UVC germicidal lamp tube, and the plasma generator 5. The operation of the first fan body 22, the second fan body 41, and the plasma generator 5 is controlled by pressing the knobs. In another implementation, the controller is connected to the fan knob 110, the light-emitting knob 111, and the plasma knob 112. The controller is also connected to the first fan body 22, the second fan body 41, the UVC germicidal lamp, and the plasma generator 5. The controller receives control signals from the knobs and controls the first fan body 22, the second fan body 41, the UVC germicidal lamp, and the plasma generator 5 according to a preset program. The controller can be an MCU chip. The controller can also be equipped with a timing control unit to set the alternating or synchronous working cycle of the first fan body 22, the second fan body 41, the UVC germicidal lamp, and the negative ion generator.

[0054] In this embodiment, an ambient light sensor is installed next to the light-emitting knob 111. The ambient light sensor is connected to the controller. When the controller receives the ambient light detected by the ambient light sensor and finds it to be below a certain illuminance, the UVC germicidal lamp is turned off. Because bacteria's DNA is damaged by UVC light, visible light (natural daylight / indoor lighting) will activate bacterial repair enzymes to repair the damaged DNA and revive them (photoresurrection effect): In bright environments, bacteria are more likely to revive, and UVC sterilization is greatly reduced; therefore, the UVC germicidal lamp can be turned off directly in dim light, and disinfection should only be carried out during bright, unoccupied periods to ensure thorough sterilization.

[0055] In this embodiment, a power supply interface 113AC daisy chain (Alternating Current AC) is also provided on the rear shell 11 for connecting an external power source to power the device. An AC cable can be provided to connect to external devices, such as a plant cultivation box, to enable power supply to external devices.

[0056] In this embodiment, the housing 1 is provided with a mounting groove 6, which is used for mounting the plant growth assisting device on an external device. The mounting groove 6 is fitted with U-shaped mounting brackets whose length and dimension can be adjusted by sliding left and right. Two U-shaped mounting brackets are fittingly installed on both sides of the plant growth assisting device to form a structure shaped like the Chinese character "mu" or "ri", which can adapt to planting racks of different widths. Meanwhile, the U-shaped mounting brackets can be folded with their U-shaped portions facing each other, so as to detachably mount the entire device on the inner wall, top of the plant incubator or below the partition plate of the planting rack.

[0057] The above description is only the preferred embodiments of the present invention, and is not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the description and accompanying drawings of the present invention, or any direct or indirect application in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
