A suction nozzle for use in a vacuum cleaner includes a floor nozzle (11) and a mini nozzle (10) having a suction head (40), a rotatable joint (8), and joint (9), to be detachably secured in the floor nozzle (11). Either of the suction head (40) and the rotatable joint (8) or the rotatable joint (8) and the joint (9) is vertically joined and the other rotatably joined. Moreover, the suction head (40) is unrotatably secured onto the floor nozzle (11), and forms an air communication with the floor nozzle (11).

The invention provides a communication system with a group registration function, which is capable of setting a group mode with the reduced number of operation, and simply selecting one of full duplex communication and half duplex communication by a rider, as needed. To achieve this, in a communication system with a group registration function, when a power supply SW (switch) and a registration SW are turned on simultaneously (answer in step S1 is affirmed), member ID registration is executed (step S7). On the other hand, when the power supply SW is turned on and then the registration SW is turned on (answer in step S3 is affirmed), visitor ID registration is executed (step S8). Accordingly, the registration of a group mode can be simplified. After the registration is ended, at the time of turn-off of a visitor conversation SW, full duplex communication is performed among communication devices subjected to member ID registration, and at the time of turn-on of the visitor conversation SW, half duplex communication is performed between the master and all of the slaves.

The invention provides a twin tower tandem exhaust gas purifying processing combination device which adopts a biomembrane packing tower system utilizing catalytic oxidant cyclically spraying liquid in the front and a biomembrane packing tower system utilizing pH buffering agent cyclically spraying liquid in the rear, which can carry out purifying processing to simultaneously remove the SQ2 and the NOx in the exhaust gas and to obtain by-products, namely, the utilizable sulphuric acid and nitrating acid products. The invention is characterized in that desulphuricants and denitrifier complex bacteria with the performance of simultaneously removing SQ2 and NOx in the exhaust gas under the conditions of liquid-phase catalyzed oxidation and pH acid environment can be obtained by screening and culturing and domesticating, and the composite bacteria biofilm to manufacture the biomembrane packing tower which is arranged in the tandem front end and is mainly used for removing SQ2; and the biomembrane packing tower which is mainly used for removing NOx in the rear is manufactured by adopting the denitrifier complex bacteria biofilm with the performance of removing NOx in the exhaust gas under the condition of pH neutral environment through screening and culturing and domesticating.

The invention discloses a method for extracting active ingredients in ginger, and relates to the technical field of extraction of plant effective substances, comprising the following steps: (1) Grinding dried ginger with an extrusion crushing device to obtain ginger juice and ginger powder, and crushing the ginger powder until the 20-60 mesh sieve; (2) ginger juice and ginger powder are mixed, mixed according to the ratio of 1g ginger to 4-9ml ethanol, and ultrasonic treatment is performed for 13-20min to obtain filtrate A and filter residue A; (3) filtrate A and Equal volumes of petroleum ether were mixed, and allowed to stand for stratification, and the upper liquid was separated to obtain filtrate B, and the lower liquid was filtrate C; (4) Filtrate B and filtrate C were respectively subjected to suction filtration and concentration, and filtrate B was concentrated to obtain ginger essential oil , After the filtrate C was concentrated, the crude product of gingerol was obtained. The method for extracting active ingredients in ginger provided by the invention can effectively separate gingerol and ginger essential oil, and can improve the extraction rate of active ingredients in ginger.

The invention discloses a forming process of a high quality chemical fiber blanket, the forming steps of a first chemical fiber blanket surface and a second chemical fiber blanket surface comprise: (1) combing and tapping natural bamboo fibers to form a basilar part of a chemical fiber blanket surface; (2) laying a layer of annular fiber on the upper part of the basilar part of the chemical fiberblanket surface; (3) laying polypropylene fiber which is used for connection on the annular fiber layer; (4) fixing a connection layer formed in the step (3) and the annular fiber layer formed in thestep (2) on the basilar part of the chemical fiber blanket surface through needling; (5) cutting the annular fiber by adopting a cutting tool so as to form chemical fiber wool on the first chemical fiber blanket surface and the second chemical fiber blanket surface, the depth of the cutting tool is smaller than the sum of thickness of the annular fiber layer and the connection layer. Compared withthe prior art, the forming process of the high quality chemical fiber blanket has the characteristics of reasonable design, convenient use and good ventilation effect.

Provides a group mode setting that can be set with a small number of operations, and matches the desired use scene, and the driver can easily use full-duplex and half-duplex communication devices with group registration functions separately. In the communication device having a group registration function, if the power supply SW and the registration SW are turned on at the same time (Yes in step S1), the operation proceeds to member ID registration (step S7). On the other hand, if the login SW is turned on after the power source SW is turned on (Yes in step S3), it proceeds to the operation of visitor ID registration (step S8). Therefore, the login of the group mode is simplified. When the above registration is completed, when the visitor call SW is disconnected, full-duplex communication is performed between the communication devices registered with the member ID, and when the visitor call SW is connected, half-duplex communication is performed for all slaves communication.

The invention relates to a fermented grain layered distillation aroma-raising method, belonging to the technical field of white spirit distillation. The invention aims at providing the fermented grain layered distillation aroma-raising method. The method comprises the following steps: a) upper fermented grains are taken out from the fermented grains in a fermentation pit to stack separately; b) then the fermented grains are successively taken out from the fermentation pit from top to bottom to stack to the yellow water line position of the fermentation pit layer by layer from bottom to top, wherein the stacked fermented grains are upper grains; c) the fermented grains which are below the yellow water line and above bottom fermented grains are taken out to stack according to the way of thestep b), wherein the stacked fermented grains are lower grains; d) the bottom fermented grains are taken out to stack separately; and e) the upper fermented grains and bottom fermented grains are separately distilled for wine taking, the upper fermented grains and the bottom fermented grains are loaded in a steaming bucket according to the volume ratio of 1-3:1-3, the upper fermented grains are filled in the bottom of the steaming bucket, the bottom fermented grains are filled in the upper part of the steaming bucket, and distillation is performed for wine taking.
