Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically to a humidifier for spraying microbial solutions onto tobacco leaves. Background Technology

[0002] As people's awareness of pollution-free production and consumption increases, pollution-free and organic foods are becoming more valued by consumers. Currently, beneficial microorganisms have made considerable progress in tobacco pest and disease control, as well as in improving tobacco yield and quality. Many microbial pesticides and fertilizers have been applied in tobacco production practices, yielding significant economic and social benefits.

[0003] The common applications of microorganisms in tobacco mainly involve: 1. Microecological tobacco field improvement refers to the use of microbial technology and microbial tobacco organic fertilizer to improve the soil in tobacco fields; 2. Microbial aroma enhancement involves using both endogenous and exogenous aroma-enhancing microorganisms in tobacco leaves for comprehensive processing. This can, on the one hand, enhance the aroma of cigarettes, and on the other hand, reduce harmful substances in the tobacco leaves.

[0004] There are two main processes by which microorganisms enhance aroma. One is by spraying microorganisms onto the surface of tobacco leaves in the field. For example, the paper "Study on Improving the Usability of Upper Leaves of Flue-cured Tobacco by Spraying Microbial Agents" clearly states that microbial agents promote cell growth and division in the upper leaves, increase leaf area, degrade some macromolecular organic compounds to form low-molecular-weight aroma substances or aroma precursors, and appropriately reduce nicotine and protein content. The other process involves spraying microbial preparations onto tobacco leaves placed in the curing barn after harvesting or during the re-curing process. Utilizing specific functional bacteria (such as yeasts and lactic acid bacteria that promote tobacco leaf aging), the aroma quality of tobacco leaves can be improved, and the content of harmful components can be reduced.

[0005] Based on the above-mentioned tobacco field and curing barn usage environment, the existing optional equipment is agricultural sprayer. However, during use, agricultural sprayer has the problem of insufficient atomization effect. If the size of the atomizing nozzle is further reduced, the nozzle is prone to clogging.

[0006] Meanwhile, existing sprayers tend to cause microbial agents to settle when spraying microbial solutions; furthermore, microorganisms are easily contaminated by other bacteria, and existing sprayers lack sterilization measures, which affects the activity of the microbial agents. Utility Model Content

[0007] In view of this, the technical problem to be solved by this utility model is to provide a humidifier that is not easy to clog or settle and is not easily contaminated by miscellaneous bacteria, which is specifically used for spraying microbial solutions onto tobacco leaves, thus overcoming the shortcomings of the prior art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a humidifier for spraying microbial solution onto tobacco leaves, comprising a container and a battery, a covered feeding port on the container, an ultrasonic atomizer inside the bottom of the container, an air inlet and a mist outlet on the upper part of the container, a fan connected to the air inlet, a spray hose connected to the mist outlet, two or more mist outlets on the side of the spray hose, a plug at the end of the spray hose, and a metal hose that is easy to hold and can be bent at any angle connected to the spray hose, and the battery, ultrasonic atomizer, and fan are connected to the humidifier.

[0009] The humidifier used to spray microbial solution onto tobacco leaves has an ultraviolet lamp (6) in the upper part of the container, which is connected to a storage battery.

[0010] The aforementioned humidifier for spraying microbial solution onto tobacco leaves also includes an external stirring device. The stirring device includes a motor, a stirring shaft, stirring claws, and a fixed cover. The fixed cover has a through hole. The stirring pump passes through the through hole of the fixed cover and is connected to the motor. The stirring claws are connected to the stirring shaft. The motor and the battery are pluggable.

[0011] The aforementioned humidifier for spraying microbial solution onto tobacco leaves has an air distributor in the air inlet, a hose connector on the air distributor, a ventilation pipe connected to the hose connector, and the other end of the ventilation pipe located at the bottom of the container.

[0012] The aforementioned humidifier for spraying microbial solutions onto tobacco leaves has a carrying strap on one side of the container for easy carrying.

[0013] Compared with existing technologies, this invention features a humidifier specifically designed for spraying microbial solutions onto tobacco leaves, tailored to the characteristics of microbial spraying. It abandons existing high-pressure atomizing nozzles and employs an ultrasonic atomizer. A fan drives the ultrasonic atomizer to generate atomized particles, which are then sprayed onto the tobacco leaves through a spray hose. The ultrasonic atomizer is positioned at the bottom of the container, where high-frequency ultrasonic vibrations generate tiny bubbles within the liquid. These bubbles rapidly expand and burst, creating localized high pressure and shock waves, forming a water mist. The fan's airflow propels this water mist out of the spray hose, achieving the spraying of microbial-containing water mist onto the tobacco leaf surface. Two or more mist outlets are located on the side of the spray hose, and a plug is provided at the end. A flexible metal hose, easy to hold and bend at any angle, is connected to the spray hose. This allows the shape of the spray hose to be adjusted according to the area of ​​the tobacco leaf to be sprayed, and the airflow path is optimized using an air duct to ensure efficient water mist delivery to the tobacco leaf surface.

[0014] Meanwhile, the water droplets produced by ultrasonic atomization are typically 1-5 micrometers in diameter. Such tiny particles are significantly affected by collisions with air molecules, exhibiting strong Brownian motion (random thermal motion), making it difficult for water droplets to collide and combine with each other. Furthermore, due to the high specific surface area of ​​these tiny water droplets, surface tension dominates. In addition, during ultrasonic atomization, water droplets may carry charges due to friction or cavitation effects. The electrostatic repulsion between like charges makes it difficult for water droplets to coalesce. This allows for more uniform spraying, especially when used in drying rooms, as it can prevent water stains and smoke.

[0015] An ultraviolet lamp is installed at the top of the container, which can be used to disinfect the container before adding microorganisms, thus preventing the microorganisms from being contaminated by other bacteria.

[0016] The external mixing device allows for rapid mixing of microorganisms with the liquid, and its external design reduces the carrying weight when used in the field.

[0017] An air distribution plate is installed inside the air inlet, and a flexible hose connector is installed on the air distribution plate. A vent pipe is connected to the flexible hose connector, and the other end of the vent pipe is located at the bottom of the container. This air distribution setting allows some gas to enter the container through the vent pipe to stir the liquid, prevent microbial sedimentation, and improve uniformity.

[0018] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

The container 1 is made of engineering plastic and has a battery and a switch for controlling start and stop at its bottom. A carrying strap is provided on one side of the container 1 for easy carrying. An ultrasonic atomizer 3 is located inside the bottom of the container 1. The upper part of the container 1 has a covered feeding port 2, an air inlet 4, and a mist outlet 5. A fan 7 is connected to the air inlet 4, and a spray hose 8 is connected to the mist outlet 5. The spray hose 8 is a corrugated hose with a diameter of 6-12cm. Two or more mist outlets 9 are opened on the side of the spray hose 8, located on the same side of the spray hose 8, with a diameter of 2-6cm. A plug is provided at the end of the spray hose 8. A metal hose 10 that is easy to hold and can be bent at any angle is connected to the spray hose 8. This metal hose is commonly found on lamp supports that can be adjusted at any angle. The battery, ultrasonic atomizer 3, and fan 7 are connected.

[0023] To disinfect the container, an ultraviolet lamp 6 is installed in the upper part of the container 1, and the ultraviolet lamp 6 is connected to the battery.

[0024] To ensure rapid and uniform mixing of microorganisms with water, this device is also equipped with an external stirring device. The stirring device includes a motor 11, a stirring shaft 12, a stirring claw 13, and a fixing cover 14. The fixing cover 14 has a through hole. The stirring claw 12 passes through the through hole of the fixing cover 14 and is connected to the motor 11. The stirring claw 13 is connected to the stirring shaft 12. The motor 11 is pluggable to the battery. In this way, it is connected to the feeding port 2 during stirring and removed during spraying to reduce weight.

[0025] To prevent microbial sedimentation during spraying, an air distributor 15 is installed inside the air inlet 4, and a hose connector 16 is installed on the air distributor 15. Figure 3 As shown, the air distribution plate 15 is a plastic sheet, with 3 / 4 of it being a normally open through hole and 1 / 4 being an open plug plate. The hose connector 16 is connected to the open position of the plug plate, and a vent pipe 17 is connected to the hose connector 16. The other end of the vent pipe 17 is located at the bottom of the container 1. This air distribution setting allows some gas to enter the container through the vent pipe to stir the liquid, prevent microbial sedimentation, and improve uniformity.

[0026] Before use, turn on the UV lamp 6 for sterilization for 10-30 minutes. This can be done at home or on the way. After arriving at the tobacco field, open the feeding port 2, add the microbial agent to the container 1, place the filter screen and add water, then install the external stirring device. After turning on the power, stir for 10-15 minutes. Remove the external stirring device, close the feeding port 2 tightly, turn on the ultrasonic atomizer 3 and the fan 7, and wait for 2-3 minutes until mist appears at the mist outlet 9.
