However, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example 2

[0021] See also Figure 1 , a plant essential oil extraction and collection device with a bubble suppression function, comprising an extraction tank 1, a condenser 2, a collection bottle 3, a bubble suppression component 4, connecting pipes and control components, the extraction tank 1 is equipped with a heating system, the heating system is an electric heating wire or steam heating, the bubble suppression component 4 includes a defoaming net 41, a defoaming agent adding device 42, and a gas-liquid separation structure 43, the defoaming agent adding device 42 also includes a stirrer for rapid mixing of the defoaming agent, the gas-liquid separation structure 43 is a separation chamber based on the principle of gravity sedimentation, the defoaming net 41 is arranged in the extraction tank 1 and the condenser 2, and a defoaming net 41 is arranged on the condenser 2 at the same distance, the defoaming agent adding device 42 includes a defoaming agent storage tank 421 and a metering component 422, and the gas-liquid separation structure 43 is arranged on the connecting pipe between the extraction tank 1 and the condenser 2; the condenser 2 is a spiral structure, and a circulating cooling system is provided outside the condenser 2.

[0022] The plant material that has been pretreated (such as crushing, drying, etc.) is placed in the extraction tank 1, and the heating system is started to raise the temperature in the extraction tank 1 to an appropriate extraction temperature range. At the same time, the stirring device is turned on to allow the plant material to be heated evenly. The essential oil components therein gradually evaporate into a gaseous state under the action of high temperature, and mix with water vapor to form mixed steam. These mixed steams enter the condenser 2 along the connecting pipe; after the mixed steam enters the condenser 2, under the action of the circulating cooling system, the heat is continuously taken away, the steam temperature is reduced, and then it is liquefied into a liquid state, and flows along the inner wall of the condenser to the collection bottle below, thereby realizing preliminary essential oil collection; a defoaming net 41 is set in the extraction tank 1 and in the connecting pipe and other places where bubbles are easily generated. The defoaming net is woven from fine metal wire or special polymer materials, and its mesh size can be designed and adjusted according to the actual bubble size. When a mixed liquid or steam containing bubbles passes through the defoaming net, the bubbles will burst at the mesh, thereby reducing the number of bubbles; a special defoaming agent storage tank 421 is equipped and connected to key parts such as the extraction tank 1 and the collection bottle 3 through a precise metering pump. When too many bubbles are detected (which can be monitored by a bubble sensor installed in the corresponding part), the metering pump will inject the defoaming agent into the corresponding area according to the set dosage. The defoaming agent can change the surface tension and other properties of the liquid, causing the bubbles to quickly burst and dissipate; a gas-liquid separation structure is set at the entrance of the collection bottle or on the connecting pipe between the extraction tank and the condenser. Common ones include cyclone separators designed using the principle of centrifugal force, or separation chambers based on the principle of gravity sedimentation. After the mixed gas and liquid enter, the gas and liquid are separated under the action of the gas-liquid separation structure, the gas is discharged from the device, and the liquid continues to flow to the collection bottle. This can effectively prevent bubbles from entering the collection bottle and affecting the purity and subsequent preservation of the essential oil.

[0023] The above examples are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above examples, and many similar modifications are possible. All modifications that can be directly derived or imagined by a person skilled in the art from the disclosure of the present invention should be considered to be within the scope of protection of the present invention.
