The invention relates to an active noise reduction range hood and a noise reduction method thereof. A noise signal is decomposed into multiple sub-band signals, the sub-band signals are converted to obtain band pass filter weight vectors, the obtained band pass filter weight vectors are converted to generate corresponding loudspeaker sound fields, the equal-intensity sound wave signals are transmitted to corresponding loudspeakers, and sound waves generated by the corresponding loudspeakers can reduce or offset noise sound waves generated by the range hood in order to realize noise reduction.The arrangement of a low-damping full sounded or half surrounded structure and a self-adaption function of the active noise reduction range hood achieves the optimization of the performances of the range hood, realizes the completion of working under low-nose running conditions, and solves the technical difficulty of the mutual contradiction between noises and performances, and low noises generated during running of the range hood and no physiologic and mental negative influences on users are achieved without sacrificing the smoke suction performance of the range hood.

The invention discloses a cold air prevention control method applied to a vertical air conditioner provided with infrared sensors and further discloses a cold air prevention control device, the vertical air conditioner and a computer readable storage medium. The cold air prevention control method comprises the following steps that infrared data detected by the infrared sensors within the continuous time and preset motion parameters are obtained; according to the obtained infrared data, the obtained preset motion parameters and the quantity of the infrared data, the current motion quantity of adetected object in front of the vertical air conditioner is calculated, and thus the motion value is obtained; and according to the motion valve, the vertical air conditioner is controlled to executea child cold air prevention strategy. The risk that a child catches uncomfortable symptoms of having a running nose or having a cough or the like due to being located in front of the vertical air conditioner for a long time can be reduced, and accordingly the using experience of users in the child cold air prevention function is improved.

The range hood is provided with a range hood main body and the inferior three-dimensional space sound field noise reduction device for active noise reduction, and the three-dimensional space sound field noise reduction device is assembled in the range hood main body. A noise signal is decomposed into multiple sub-band signals, the sub-band signals are converted to obtain band pass filter weight vectors, the obtained band pass filter weight vectors are converted to generate corresponding loudspeaker sound fields, the equal-intensity sound wave signals are transmitted to corresponding loudspeakers, and sound waves generated by the corresponding loudspeakers can reduce or offset noise sound waves generated by the range hood in order to realize noise reduction. The arrangement of a low-damping full sounded or half surrounded structure and aself-adaption function of the range hood achieves the optimization of the performances of the range hood, completes working under low-nose running conditions, and solves the technical difficulty of the mutual contradiction between noises and performances, and low noises generated during running of the range hood and no physiologic and mental negative influences on users are achieved without sacrificing the smoke suction performance of the range hood.

The invention discloses a paracetamol, diphenhydramine hydrochloride and phenylephrine hydrochloride oral solution and a preparation method thereof. The paracetamol, diphenhydramine hydrochloride andphenylephrine hydrochloride oral solution is a novel medicine developed for overcoming the defects that the existing cold-treating medicines for children in China have few varieties, few dosage forms,too large dosage, incomplete specifications, difficultly accepted taste and the like; and the paracetamol, diphenhydramine hydrochloride and phenylephrine hydrochloride oral solution can treat cold-induced symptoms such as headache, mild pain, pain, nasal congestion, a runny nose, sneezing, cough, fever and a sore throat. The paracetamol, diphenhydramine hydrochloride and phenylephrine hydrochloride oral solution is a fruity oral liquid preparation mainly for 6-12-year-old children with a cold.

The invention discloses a medicine composition for treating chronic rhinitis and a preparation method of the medicine composition. Water is adopted as solvents for preparing medicine raw materials into liquid spraying agents or nasal drops, and the medicine raw materials comprise the following ingredients in parts by weight: 7 to 13 parts of sal ammoniac, 7 to 13 parts of rose mallow root, 7 to 13 parts of sodium chloride and 7 to 13 parts of distilled water. The medicine composition belongs to a chronic rhinitis treating medicine composition with the advantages that the advantages of all doctors are integrated, the proved recipes of Chuang doctors and Chuang medicine are combined, the screening is carried out, the effects of dispelling the wind to clear away heat and diffusing the lung to dredge qiao are realized, and the clinical curative effect is obvious. The medicine composition has the obvious curative effect on chronic simple rhinitis and symptoms such as nasal obstruction, nose running, sternutation and the like caused by anaphylactic rhinitis, the cure rate is 97.6 percent, the pathological worsening can be effectively suppressed, safety and reliability are realized, no adverse reaction exists, most patients can be thoroughly cured, and the treating cost is low. The medicine material production source is rich, the preparation process is simple, the cost is lower, higher market competitiveness is realized, and economic benefits and social benefits are better.

The invention discloses a range hood with an oil-resistant three-dimensional space sound field noise reduction device, and a noise reduction method thereof. A noise signal is decomposed into multiplesub-band signals, the sub-band signals are converted to obtain a band pass filter weight vector, the obtained band pass filter weight vector is converted to generate a corresponding loudspeaker soundfield, the equal-intensity sound wave signal is transmitted to a corresponding loudspeaker, and sound waves generated by the corresponding loudspeaker can reduce or offset noise sound waves generatedby the range hood in order to realize noise reduction. The arrangement of a low-damping full sounded or half surrounded structure and a self-adaption function of the range hood with the oil-resistantthree-dimensional space sound field noise reduction device achieves the optimization of the performances of the range hood, completes working under low-nose running conditions, and solves the technical difficulty of the mutual contradiction between noises and performances, and low noises generated during running of the range hood and no physiologic and mental negative influences on users are achieved without sacrificing the smoke suction performance of the range hood.
