A backpack tool, a backpack blower and a control handle assembly are provided by the present invention. The backpack tool includes a battery pack for providing electrical energy, a power assembly electrically connected with the battery pack to convert the electrical energy provided by the battery pack into mechanical energy, and a backpack assembly carried on the human back to support the battery pack and the power assembly. Both the battery pack and the power assembly can be carried on the human back using the backpack assembly, so that the weight carried by the arms of the worker can be reduced. The battery pack serves as a power source that reduces the noise and vibration caused by the backpack tool during operation as compared with a gasoline powered backpack tool.

Piggyback working appliance, piggyback blower, and control handle assembly

The present invention relates to the field of pharmaceutical chemistry, and specifically relates to a fused heterocyclic compound derivative and an application thereof. The fused heterocyclic compound derivative has the structure of general formula (I), and can be used to treat neuropsychiatric diseases. 

Fused heterocyclic compound derivative and application thereof

The present invention relates to a lactam compound derivative, a medicine composition comprising the lactam compound derivative, and uses of the composition and the lactam compound derivative in preparation of a medicine for preventing or treating schizophrenia, the lactam compound derivative having a structure as shown in Formula I. 

Lactam compound derivative and application thereof

An electrical system with replaceable batteries comprises an electrical system and a combined switch. The electrical system comprises a plurality of battery packs (); all the battery packs are independently arranged each other; and an electric-quantity display device which is used for displaying the electric-quantity information indicating signals of the battery packs and a gear switch which is used for mutually switching the battery packs are arranged on the combined switch. Each battery pack comprises a battery (A, A, A), a power switches (B, B, B) and a battery management system (C, C, C). The battery management systems receive and combine the output signals of the combined switches with the electric-quantity information indicating signals, thereby controlling whether the power switches are closed to provide power output or not.

Electrical system with replaceable batteries

A brush-less motor is disclosed, comprising a stator, a rotor, a plurality of field-effect tubes, a commutation circuit board, a control circuit board and a motor end cap, wherein the motor end cap comprises a front end cap and a rear end cap which are mutually fixedly connected to form an integrated motor; the plurality of field-effect tubes is directly fixed at the motor front end cap; the commutation circuit board and the control circuit board are both connected to the motor front end cap. The field-effect tubes of the brush-less motor are directly installed on a housing of the motor, ensuring good heat dissipation, saving heat sinks and cost; the integrated brush-less motor runs more smoothly and imposes requirements which are not as high as those imposed by the split brush-less motor on the accuracy of the housing. Thus, the reject ratio of products during batch production is reduced.

Brush-less motor

The present invention relates to the field of pharmaceutical chemistry, and in particular, to a benzopyrone derivative and a use thereof. The benzopyrone derivative is compound having a structure of formula (I) or a pharmaceutically acceptable salt thereof. It has been found by experiments that, this type of compounds is useful in prevention or treatment of neuropsychical diseases. 

Benzopyrone derivative and use thereof

Disclosed are alicyclic[c]benzopyrone derivatives and use thereof. The alicyclic[c]benzopyrone derivatives are compounds represented by formula I or their salts. The present compounds not only significantly improve high activity induced by MK-801, but also effectively improve clambering symptom induced by Apomorphine and do not cause EPS within effective dose. These in vitro targets and in vivo pharmacological models are closely related to diseases of the nervous system caused by dopamine dysfunction, especially schizophrenia. Therefore the present compounds can be used for the treatment of central nervous system diseases, especially schizophrenia. EDis lower and effect is stronger in two animal models i.e. high activity induced by MK-801 and clambering symptom induced by Apomorphine, while EDis higher and therapeutic index is greater in animal models of catalepsy. 

Alicyclic[c] benzopyrone derivatives and uses thereof

The present invention belongs to the medicinal chemistry field, and specifically discloses a [1,3,4]oxadiazole derivative with the structure of general formula (I) and pharmaceutically acceptable salt thereof. The compound can be used to prepare a medicine for preventing or treating a disease of the central nervous system.
