The invention discloses a motorcycle exhaust pipe. A muffler is arranged outside the exhaust pipe. Filters are arranged in the exhaust pipe and comprise the pipe wall filter and the outlet end filter. The pipe wall filter is arranged in the exhaust pipe and connected to the inner wall of the exhaust pipe and comprises a supporting net, a filter core, a filter net and a filter layer from outside to inside. The outlet end filter is arranged at the outlet end of the exhaust pipe. The inlet end of the exhaust pipe is in threaded connection with the exhaust port of an engine air cylinder. Fastening devices are arranged at the inlet end of the exhaust pipe and the exhaust port of the engine air cylinder. A silencer is further arranged in the exhaust pipe to reduce noise pollution in cities. Through the double filters, the purification efficiency of motorcycle tail gas can be improved, and the filter effect is good.

The invention discloses an efficient crushing and separating method for eggshells and shell membranes obtained by incubation and hatching of hatching eggs of poultry. The efficient crushing and separating method comprises the following step: performing suffumigating, drying, primary crushing, vibration screening, electric windwill separation and the like on a complete eggshell (including inner and outer layers of shell membranes) obtained by incubation and hatching. The method is high in crushing and separating efficiency, and the purity of obtained products, i.e. eggshell powder and shell membrane powder, is 98 percent or above, and the moisture content is less than 8 percent; the obtained products are free of pathogenic bacteria, nontoxic, harmless, pollution-free and safe; furthermore, the natural attributes of the eggshells and shell membranes which are obtained by incubation are retained, and the products meet the feed level standard; and the method is suitable for batch processing of breeding poultry incubation fields of different scales, and the eggshells and the shell membranes can be separately used or combined for use so as to develop the breeding value of the nutrition and the functionality of the eggshells and the shell membranes, improve the productivity of the poultry and the disease resistance of livestock, realize reuse of complete eggshell resources obtained by the incubation and reduce the pollution to the environment.

The invention provides an air conditioner control method and device, a storage medium and an air conditioner. The method comprises the steps of: obtaining a first temperature change speed of primary operation of the air conditioner and a second temperature change speed in present operation; and judging if an air purifying device of the air conditioner needs to be started according to the first temperature change speed and the second temperature change speed. The method can automatically judge indoor and outdoor air interaction conditions of the air conditioner according to the temperature change speed of reaching a target temperature in primary operation of the air conditioner and the temperature change speed of reaching the target temperature in present operation to judge if the air purifying device is started so as to improve indoor air quality.
