Description

Plant fragrance diffuser Technical Field The invention belongs to the field of intelligent home furnishing, and particularly relates to a plant fragrance diffuser. Background With the continuous improvement of indoor environment quality requirements, space odor management has become a conventional matching means in commercial and human-living scenes. The prior art generally adopts a scheme of liquid fragrance source and ultrasonic/compression atomization, namely essence, essential oil or functional liquid fragrance agent is crushed into micron-sized liquid drops through a high-frequency vibration or pressure nozzle, and then the liquid drops are brought into air supply flow through an independent fan or an air conditioner return air inlet, so that rapid diffusion is realized. The scheme has simple structure and quick effect, but the following commonality problems are exposed in long-term operation: The atomized fragrance carrier is mainly VOCs and PM2.5 level liquid drops, the initial concentration of the fragrance carrier is too high, and obvious smell "aggressiveness" is formed. The aromatic perfume has the advantages that the aromatic perfume can be used in places requiring more than 8 hours for fragrance supply, such as offices, medical treatment, education and the like, the user is easy to have eye, nose and throat irritation, headache and allergy symptoms, and the potential chronic toxicity risk exists after aldehydes and benzene series in part of the aromatic perfume are accumulated in a closed space. Most of the liquid perfume sources are chemically compounded, the natural plant slow release is lacked in 'front-middle-back regulation' level change, the smell is monotonous and easy to fatigue, and accompanying effects such as negative oxygen ions, phytoncide and the like cannot be generated, so that the liquid perfume source has a large difference from the 'forest bath' and 'natural perfume' concept. After the fragrance enters the space along with the air supply of the air conditioner, the flow direction of the fragrance is limited by the swing angle of the traditional louver grid, and only fixed conical or fan-shaped jet flow can be formed. For a large interval with the layer height of more than 3.5m and the area of more than 100m 2, the concentration distribution of the fragrance in a personnel activity area is uneven, the area close to the air supply opening is too thick, the far-end area is lower than the olfactory threshold value, and the initial injection quantity is required to be increased for compensation, so that the hidden health trouble is further aggravated. Disclosure of Invention In view of the above, the present invention is directed to a plant fragrance diffuser, so as to solve the problems of injury to human body and limited air supply angle and distance of the traditional fragrance management system. In order to achieve the purpose, the invention adopts the following technical scheme that the plant fragrance diffuser comprises: The crushing assembly is provided with an inlet end and an outlet end and is used for crushing plants, inputting aromatic compounds into the fragrance activating assembly and completing self-cleaning; The fragrance activating assembly is connected with the outlet end of the crushing assembly and is used for heating and activating the aromatic compound, enabling the aromatic compound to flow through the heating area under the wrapping of the protection airflow and accelerating output at the Venturi effect nozzle; The fragrance dispersing component is connected with the Venturi effect nozzle, a plurality of fifth nozzles with adjustable directions are arranged on one side end face, a gas dispersing part for filtering and exhausting gas is arranged on the periphery side, and the fragrance dispersing component is further provided with a monitoring module for controlling the plurality of fifth nozzles to act and reversely blow air to the target side after detecting the position of a human body, and activated aromatic compounds are blown out from the target side through the gas dispersing part through reverse acting force. Still further, smash the subassembly including smashing the chamber, set up at the double-deck cutting portion of smashing the intracavity, set up at smashing the chamber top and be used for spraying a plurality of first nozzles of cleaner, set up sterilization unit, piezoceramics transducer and the detection module on smashing the chamber perisporium, wherein, double-deck cutting portion is provided with two at least relatively rotatable cutters, the detection module detects the reverse rotation between the cutter when unusual. Still further, smash the chamber bottom and be provided with filter element and waste recycling portion, waste material is through filter element filters the back get into waste recycling portion retrieves. Further, the double-layer cutting part is provided with two layers, is vertically spaced and is coaxially arranged
