Description

Technical Field

[0001] The invention belongs to the technical field of volatile gas collection, and in particular relates to a plant volatile gas collection device and method. Background Art

[0002] Plants release various volatile organic compounds (VOCs) during their growth, such as isoprene and terpenes. Collecting these volatile gases can help scientists understand the physiological processes of plants, including photosynthesis, respiration, etc.; and the gases emitted by plants have potential effects on atmospheric chemical composition, greenhouse effect and global climate change. By collecting and analyzing these gases, researchers can evaluate the impact of plants on the environment and how these gases participate in atmospheric chemical reactions; in addition, the gases emitted by plants may also contain valuable compounds. Collecting and analyzing these gases can help discover new food additives, spices or drug ingredients. In particular, plant floral fragrance is a class of volatile small molecule compounds released by plants. These compounds not only give flowers a unique fragrance, but these fragrances are also very important in biology, medicine, industrial applications and daily life. In biology, using fragrance to attract pollinators such as insects and birds can effectively increase the probability of plant pollination, thereby achieving plant reproduction; and some plants can protect themselves from harm by releasing specific odors to drive away natural enemies or pests. In medicine, floral scent is widely used in aromatherapy to relieve stress, anxiety, enhance mood, improve sleep quality, etc. In industrial applications, floral scent is an important source of essential oils and perfumes.

[0003] However, although a variety of collection methods have been developed for the collection of plant volatiles such as perfume, such as distillation, microwave drying, vacuum extraction, extraction, and fat cold soaking, these extraction methods have a common feature that they require the flowers containing fragrance to be picked as the extraction object, and the volatile compounds in the flowers are the main components of the flower fragrance. These compounds will continue to evaporate when the flowers are open. Once the flowers are picked, the volatilization rate of these compounds will accelerate, causing the flower fragrance to weaken rapidly, thereby reducing the amount of flower fragrance extracted. In order to fully collect and extract the flower fragrance, some equipment for collecting flower fragrance from the air has emerged. Although these flower fragrance collection equipment will not harm the activity of the flowers, the amount of flower fragrance collected mainly depends on the free diffusion of the flower fragrance. It takes a long time to extract a large amount of flower fragrance, and the collection cycle is relatively long, and the concentration of the collected flower fragrance is relatively low. For example, a Chinese patent with publication number CN213364364U discloses a floral fragrance collection system for woody living flowers, including a bracket and a floral fragrance collection device arranged on the bracket, the floral fragrance collection device including a sealed gas sampling bag, a trachea, an air pump and an adsorption device, the sealed gas sampling bag is sealed and sleeved on the flowers, the sealed gas sampling bag, the trachea and the air pump form a closed-loop airflow system, and the adsorption device is arranged between the sealed gas sampling bag and the air pump to absorb the floral odor. The device uses a sealed gas sampling bag to wrap the flowers, so that the volatile substance gas carrying the flowers circulates in and out of the sealed gas sampling bag through the action of the air pump, thereby realizing the collection of fragrance and ensuring the activity of the flowers. However, when the above-mentioned collection method uses the pump body for gas circulation, the in-and-out gas movement path can only act on the local position of the flowers to realize the absorption of the floral fragrance that is freely diffused by the flowers. Only a small amount of floral fragrance can be collected in a single gas circulation process, and a large amount of gas is often required to be injected in the entire cycle of the flower opening, resulting in a larger mixing ratio of the volatile substances of the flowers and the gas, and a smaller concentration of the collected floral fragrance. Another example is the Chinese patent with publication number CN211374645U, which discloses a device for collecting flower aroma compounds, including a collection hood, a solid phase extraction tube and a vacuum pump. The collection hood is provided with an air inlet on one side and an air outlet on the other side. The air inlet is provided with an activated carbon filter membrane. One end of the solid phase extraction tube is connected to the air outlet and the other end is connected to the vacuum pump. A circular glass gasket is provided at the bottom of the collection hood, and the circular glass gasket is connected to the collection hood through a silicone gasket. The method for collecting flower aromas in this device is similar to the method of the above-mentioned patent CN213364364U. The vacuum pump is used to allow gas to pass through the collection hood. However, due to the position limitation of the air inlet and outlet on the collection hood, the movement path of the gas can only collect flower aromas from a local position of the flower. A large amount of gas needs to be continuously injected during the entire collection cycle, resulting in a small concentration of the collected flower aroma. Summary of the invention

[0042] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0044] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] The study showed that the spread of flower fragrance is closely related to temperature. In most cases, when the temperature is high, the flower fragrance will be stronger, while when the temperature is low, the flower fragrance will be relatively weak. This is because the flower fragrance is perceived by the aromatic oil molecules secreted by the oil cells in the petals through the air to our olfactory organs. The diffusion rate of aromatic oil molecules is affected by the temperature. The higher the temperature, the faster the irregular movement of the molecules, the faster the diffusion, and therefore the stronger the fragrance. In low-temperature and windless weather, the irregular movement speed of the molecules decreases, and the aromatic oil molecules diffused from the flowers are mostly gathered around the flowers. Away from the flowers, the density of aromatic oil molecules is small, and almost no fragrance can be smelled; at this time, there are very few aromatic oil molecules diffused in the air, and only when close to the flowers can the fragrance of the flowers be smelled. When the sun is bright and the atmosphere is warm or even hot, the higher temperature causes the air near the flowers to heat up quickly, which not only accelerates the irregular movement of aromatic oil molecules and speeds up their diffusion, but also further accelerates the secretion and volatilization of aromatic oils by flowers, making the fragrance of flowers stronger and releasing more.

[0046] The release of other volatile gases from plants is also closely affected by temperature. Temperature directly affects the physiological activities and biochemical reactions of plants, which in turn affects the synthesis of plant volatiles. Generally speaking, rising temperatures accelerate plant metabolic processes, including the biosynthesis of volatiles. For example, studies have found that as the temperature rises, the emission of volatile organic compounds (VOCs) from certain plants such as corn and tomatoes will increase. This is because high temperatures promote the activity of related enzymes, thereby increasing the rate of volatile production.

[0047] Thus, the present device provides the following scheme based on the physical study of the effect of temperature on the release of plant volatiles.

[0048] See also Figures 1 to 8As shown, in order to be able to collect a large amount of high-concentration floral fragrance or other volatile gases while shortening the gas collection working cycle. The present embodiment provides a plant volatile gas collection device and method, including a heat collection hood 1, a heating unit, a water mist delivery unit 3 and a water mist collection and drying unit 4. The heat collection hood 1 is a rectangular structure with an opening at the bottom, which is used to enclose the target plants during gas collection; the heating unit includes a heating part 2 and a power supply part, which are electrically connected, and the heating part 2 is arranged on the inner wall of the heat collection hood 1, and the preferred heating part 2 is arranged on the top wall of the heat collection hood 1, which is used to heat the inside of the heat collection hood 1; the water mist delivery unit 3 includes a heating water tank 32, an atomizer 33 and a first air pump 34, and a heating part 31 is arranged at the bottom of the heating water tank 32, and the heating water tank 32 is installed on the top of the heat collection hood 1, and the heating The heating part 31 is arranged between the heating water tank 32 and the heat collecting hood 1, the water inlet pipe of the atomizer 33 is placed in the water body in the heating water tank 32, the atomization outlet of the atomizer 33 is connected with the inlet of the first air pump 34, and the air outlet of the first air pump 34 is connected with the cavity of the heat collecting hood 1 through the air supply pipe 35; the suction end of the water mist collection and drying unit 4 is connected with the heat collecting hood 1, and the output end is connected with the storage cavity, and the water mist passing through the plants in the heat collecting hood 1 is collected by the water mist collection and drying unit 4 and converted into dry gas for storage.

[0049] Specifically, when collecting the fragrance of flowers or other volatile gases in the metabolism process of plants, the heat collecting cover 1 is used to cover the target plants, so that the target plants are fully placed in a closed space, which greatly reduces the loss of gas around the plants, and then the power supply part is used to provide current control for the heating part 2, so that after the heating part 2 is heated, the plants inside the heat collecting cover 1 are heated from the top of the plants; the heating part 31 is used to heat the water in the heating water tank 32, so that the atomizer 33 atomizes the heated water to form hot mist; the first air pump 34 is used to pass the hot mist from one side of the heat collecting cover 1, so that the hot mist carries a certain amount of heat to contact the plants and enters the gaps between the branches and leaves of the plants under the flow of the hot mist, so that the plants are heated from the inner and outer layers, thereby utilizing the hot mist and the heating part 2 to produce The generated heat is applied around the plants, so that the overall temperature in the heat collecting cover 1 rises to a temperature suitable for the vigorous metabolism of the plants, so as to accelerate the metabolism of the plants and increase the emission of volatile gases; then the water mist collecting and drying unit 4 is used to further collect the water mist carrying volatile gases passing through the plants and near the plants from the other side of the heat collecting cover 1, and evaporates and dries it to store it in a complete gas state, so as to collect the flower fragrance or other volatile gases of the plants. Therefore, the device, with the cooperation of the above-mentioned components, can accelerate the metabolism of the plants while maintaining the activity of the plants in the process of collecting the flower fragrance and other volatile gases of the plants, so that the volatile gases such as the flower fragrance are fully released, so as to facilitate the collection of a large amount of high-concentration flower fragrance or other volatile gases.

[0050] See also Figures 3 to 5 As shown, further, in order to enable the full release of volatile gases such as floral fragrance, it is convenient to collect a large amount of high-concentration floral fragrance or other volatile gases. The heating part 2 includes a plurality of heating lamp panels 21, and the plurality of heating lamp panels 21 are evenly distributed on the top wall of the heat collecting cover 1, and the heating lamp panels 21 are electrically connected to the power supply part. In addition, a plurality of thermometers 6 are arranged in the heat collecting cover 1, and the thermometers 6 are electrically connected to a processor, and the processor is electrically connected to the power supply part and the heating part 31 through a temperature regulator. The temperature probe of the preferred thermometer 6 is connected and lowered into the heat collecting cover 1 through an electric wire. The use of the electric wire will not cause harm to the plant. At the same time, the use of the electric wire winding facilitates the adaptive adjustment of the height of the temperature probe inside the heat collecting cover 1. The use of a plurality of temperature probes can obtain the temperature around the plant in real time from multiple positions, which is convenient for regulating the temperature inside the heat collecting cover 1.

[0051] Specifically, the use of the heating lamp board 21 enables the temperature regulator to adjust the current to achieve precise control of the heating temperature. This makes the heating process more stable and controllable. The temperature inside the heat collecting cover 1 is monitored in real time by the thermometer 6, and the temperature data is transmitted to the processor. The processor can effectively maintain the temperature inside the heat collecting cover 1 to the optimal metabolic temperature for the plant through interaction with the temperature regulator. The general temperature is usually maintained between 25°C and 30°C, which helps flowers or other plants to achieve the purpose of rapid metabolism, so that a large amount of floral fragrance or other volatile gases can be collected in a short period of time. In addition, the heat released by the heating lamp board 21 has a certain penetration ability and thermal effect, which can better increase the temperature of the plant periphery, and the small water droplets formed by the water mist refract the light released by the heating lamp board 21, which can make the heat more evenly distributed around the plant, which helps the plant to be evenly heated as a whole, thereby accelerating the metabolism of the plant and facilitating the plant to fully release volatile gases with a higher concentration.

[0052] See also Figures 3 to 6 As shown, further, in order to enable the full release of volatile gases such as floral fragrance, it is convenient to collect a large amount of high-concentration floral fragrance or other volatile gases. A diffusion plate 5 is fixedly connected to one side of the heat collecting cover 1 and close to the top wall. The cross-section of the diffusion plate 5 is arranged in a corrugated shape, and the diffusion plate 5 is a transparent material, such as an acrylic plate. Specifically, the corrugated diffusion plate 5 can further evenly diffuse the heat released by the heating lamp to avoid excessive heat concentration, and can effectively ensure the uniformity of heat dispersion in the heat collecting cover 1, so that the temperature perceived around the plant is at the same level as a whole, reaching the optimal metabolic temperature of the plant, which is convenient to accelerate the release of volatile gases and collect a large amount of high-concentration floral fragrance or other volatile gases.

[0053] See also Figure 3 and Figure 6As shown, further, in order to enable the full release of volatile gases such as floral fragrance, it is convenient to collect a large amount of high-concentration floral fragrance or other volatile gases. A plurality of shunt pipes 7 are arranged along the height direction on one side adjacent to the top of the heat collecting hood 1. The plurality of shunt pipes 7 are arranged in parallel with each other and are connected to the uniform gas supply pipe 35. The side wall of the shunt pipe 7 is evenly distributed with a plurality of air outlets along the length direction. A misting nozzle 8 is installed on each air outlet, and the spraying directions of two adjacent misting nozzles 8 have an angle. Specifically, by using atomizing nozzles 8 at multiple positions to apply hot mist into the heat collecting hood 1, and by using the change in the spraying direction of the atomizing nozzle 8, the hot mist can enter the inner layer of the plant more evenly in the overall height direction of the plant, so that the temperature of the inner layer of the plant is more uniform, so that the overall temperature inside the heat collecting hood 1 is uniform, which is convenient for maintaining the optimal metabolic temperature around the plant.

[0054] See also Figure 5 and Figure 8 As shown, further, in order to enable the volatile gases such as floral fragrance to be fully released, it is convenient to collect a large amount of high-concentration floral fragrance or other volatile gases. The water mist delivery unit 3 also includes a plurality of shunt pipes 7, and the shunt pipes 7 are connected to the inner wall of the heat collecting cover 1 through a first rotating part 9, and the first rotating part 9 is slidably connected to the side wall of the heat collecting cover 1, and the heat collecting cover 1 has a rotating shaft 91, and the rotating shaft 91 is fixedly connected to the shunt pipe 7, and the rotating shaft 91 is connected to a reciprocating motion component 10. Specifically, the reciprocating motion component 10 includes a rotary driver 101, an eccentric wheel 102, a reciprocating member, an elastic member 104 and a first gear rack group 106, and the reciprocating member is composed of a reciprocating plate 103 and two vertically arranged movable rods 105. The rotary driver 101 is fixedly connected to the outer wall of the heat collecting cover 1, and the rotary driver 101 adopts a stepping motor, and the rotary driver 101 has a rotating shaft; the eccentric wheel 102 is fixedly mounted on the rotating shaft; the reciprocating plate 103 is parallel to the rotating shaft, and the reciprocating plate 103 abuts against the upper side of the eccentric wheel 102; the elastic member 104 is arranged between the reciprocating plate 103 and the heat collecting cover 1, and the elastic member 104 adopts a spring. The movable rod 105 is arranged vertically, and its upper end is fixedly connected to the reciprocating plate 103, and its lower end is inserted into the inside of the heat collecting cover 1 from the top wall of the heat collecting cover 1 and is rotatably connected to the rotating shaft 91; the first gear rack set 106 is connected between the rotating shaft 91 and the heat collecting cover 1, and preferably, the first gear rack set 106 consists of an active rack 1061 and a driven gear 1062, the active rack 1061 is fixed on the heat collecting cover 1, and the driven gear 1062 is mounted on the rotating shaft 91.

[0055] Specifically, when in use, the rotary driver 101 is used to provide power for the eccentric wheel 102, so that the eccentric wheel 102 cooperates with the elastic member 104 to produce an up and down reciprocating motion state on the reciprocating plate 103 during the rotation process, and then the up and down reciprocating motion of the reciprocating plate 103 is used to drive the movable rod 105 to move up and down in the heat collecting cover 1, and the driven gear 1062 reciprocates accordingly. At the same time, under the meshing action of the active rack 1061 and the driven gear 1062, the diverter pipe 7 can drive the atomizing nozzle 8 to move up and down while also realizing reciprocating swing with the axis of the rotating shaft 91 as the center line. Therefore, the reciprocating swing of the atomizing nozzle 8 with the diverter pipe 7 can change the injection direction of the hot mist in the heat collecting cover 1 in real time, so that the overall temperature inside the heat collecting cover 1 can be more uniform, that is, the uniformity of the heating of the plants is achieved, which is convenient for maintaining the stability of the optimal metabolic temperature of the plants, so that the plants can fully release high-concentration volatile gases for easy collection.

[0056] See also Figure 4 and Figure 6 As shown, further, in order to fully release the volatile gases such as floral fragrance, it is convenient to collect a large amount of high-concentration floral fragrance or other volatile gases. The mist collection and drying unit 4 includes a plurality of air collecting pipes 41, a second gear rack set 43, a second air pump 44 and an evaporative dryer 45. The air collecting pipe 41 is slidably installed in the heat collecting cover 1 through the second rotating part and is located on the opposite side of the diversion pipe 7. The air collecting pipe 41 is parallel to the diversion pipe 7 and is staggered. The side wall of the air collecting pipe 41 is provided with a plurality of absorption holes 42 along the length direction. The second rotating part is preferably the same structure as the first rotating part 9, so as to facilitate the rotation of the air collecting pipe 41; the second gear rack set 43 is the same structure as the first gear rack set 106, and the second gear rack set 43 is connected to the rotating shaft 91 of the second rotating part and the reciprocating plate 103, that is, the second gear rack set 43 also includes an active rack 1061 and a driven gear 1062, the active rack 1061 is fixed to the heat collecting cover 1, the rotating shaft is connected to the reciprocating plate 103 through a movable rod 105, and the driven gear 1062 is sleeved on the rotating shaft, and the driven gear 1062 is sleeved and fixed to the rotating shaft 91 of the second rotating part. The air inlet of the second air pump 44 is connected to the air collecting pipe 41 through a conduit; the air outlet of the second air pump 44 is connected to the inlet of the evaporative dryer 45, and the outlet of the evaporative dryer 45 is connected to the storage chamber.

[0057] Specifically, the up and down movement of the reciprocating plate 103 can realize the reciprocating swing of the air collecting pipe 41 under the cooperation of the second gear rack set 43 and the second rotating part. The air collecting pipe 41 changes the air intake direction in real time through the reciprocating swing. In this way, under the action of the second air pump 44, the air collecting pipe 41 can absorb the hot mist passing through the plant from multiple directions through multiple air intakes, so that the direction of the hot mist presents multiple paths, that is, the hot mist passes through the plant from multiple directions, which can not only ensure the temperature rise of the plant periphery, but also make the inner layer of the plant achieve more sufficient temperature rise, and the flow of the hot mist can fully carry the volatile gas released by the plant, so as to fully collect the target gas. Then, under the action of the second air pump 44, the absorbed hot mist is transmitted to the evaporative dryer 45, and the hot mist is further heated and completely evaporated by the evaporative dryer 45, so that the hot mist is completely converted into dry gas, and then the gas is collected to obtain the required floral fragrance or other gas.

[0058] See also Figure 3 and Figure 8 As shown, further, in order to enable the full release of volatile gases such as floral fragrance, it is convenient to collect a large amount of high-concentration floral fragrance or other volatile gases. The first rotating part 9 has a rotating shaft 91, and also includes a telescopic rod 92 and a support seat 93. One end of the telescopic rod 92 is fixedly connected to the shunt pipe 7, and the other end is fixed on the rotating shaft 91; the support seat 93 is fixedly connected to the inner wall of the heat collecting cover 1, and the rotating shaft 91 is rotatably connected to the support seat 93. When in use, the telescopic rod 92 can be used to adjust the horizontal position of the shunt pipe 7, so that the shunt pipe 7 can be sufficiently close to the plant, so that the hot mist can fully enter the inner layer of the plant, and the volatile gas of the plant can be fully carried, so as to increase the collection concentration.

[0059] See also Figure 1 and Figure 2 As shown, in addition, the device is further provided with a solar power generation structure 11, which can collect solar energy and convert it into electrical energy to power other power units of the device, effectively saving energy consumption. At the same time, the solar power generation structure 11 is more convenient for outdoor use anytime and anywhere, and is more practical.

[0060] See also Figures 1 to 8 As shown, according to the above-mentioned plant volatile gas collection device, the method for collecting flower aroma includes the following steps:

[0061] The heat collecting cover 1 is moved to a designated position by a roller provided at the bottom of the heat collecting cover 1, and the plants from which volatile gases need to be extracted are enclosed by the heat collecting cover 1. The length of the device can be set to be variable, so that more flowers can be covered in one operation, so that the flowers are in a closed collection space inside the heat collecting cover 1.

[0062] The power supply unit, the heating unit 31 and the first air pump 34 are turned on in sequence. The power supply unit is used to provide current control for the heating unit 2 so that the heating unit 2 heats up and heats the plants inside the heat collecting cover 1 from the periphery of the flowers. The heating unit 31 is used to heat the water in the heating water tank 32 so that the atomizer 33 atomizes the heated water to form hot mist. The first air pump 34 is used to pass the hot mist from one side of the heat collecting cover 1 so that the hot mist carries a certain amount of heat and contacts the plants, and can pass through the gaps between the branches and leaves of the plants to warm up the inner layer of the plants that carry heat. The heat generated by the hot mist and the heating unit 2 is applied to the surrounding of the plants, so that the overall temperature in the heat collecting cover 1 is increased, so as to accelerate the metabolism of the plants and increase the emission of volatile gases. The multiple air inlets on the air collecting pipe 41 and the multiple air outlets on the shunt pipe 7 are used in cooperation with the reciprocating motion assembly to form multiple hot mist transmission paths that are staggered around the plants, so as to fully contact the plants. At the same time, the hot mist can be used in the form of small particles of water droplets to more fully absorb the floating flower fragrance.

[0063] The water mist collecting and drying unit 4 is then used to further collect the water mist that passes through the plant and carries the volatile gas of the plant from the other side of the heat collecting cover 1, and evaporates and dries it into a gas state for storage.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
