Due to the fact that the shell can rotate on the bottom plate, the ashtray can be used as a desktop ornament while serving as an ashtray, and meanwhile the device can be played by lifting the lifting rod. On the basis, the ashtray has a novel structure, and can be used for playing and decorating a table top.

The application discloses a novel active fireproof distribution box in the technical field of distribution boxes, which comprises a box body, and circular shafts are fixedly installed at the back of both sides of the inner cavity of the box body. The high-pressure cavity, electromagnetic valve, circular air bag and first thorn needle are arranged. When a fire breaks out inside the box body, dense smoke will be continuously generated inside the box body. At this time, the two smoke sensors can sense the generation of the dense smoke and send a signal to the controller. The controller will control the electromagnetic valve to open. At this time, the high-pressure gas in the high-pressure cavity can enter the inside of the bottom cavity. Under the action of the air pressure, the moving plate can drive the first thorn needle to move downward. Finally, the bottom end of the first thorn needle can puncture the circular air bag, so that the circular air bag is burst open. At this time, the dry powder in the circular air bag can be scattered downward, so that the effect of extinguishing the fire source inside the box body can be achieved, and the active fireproof purpose is effectively achieved.

Static contacts are fixedly connected in the upper cover and the base, a partition plate is arranged between every two adjacent static contacts, a fixing plate is connected to the side wall of the partition plate in the upper cover, the fixing plate is perpendicular to the partition plate, and an arc chute is arranged on the side, close to the static contacts, of the fixing plate. And the side wall of the cylinder body is provided with an air inlet hole for the insulation gas to enter. The arc extinguishing mechanism of the load switch has the effect of accelerating arc extinguishing.

This utility model relates to an air outlet structure for a miniature circuit breaker. By setting a first air outlet and a second air outlet on the housing, a multi-channel arc-extinguishing path is formed. During the operation of the circuit breaker, the electric arc and heat generated inside can be quickly dissipated through these two air outlets, preventing the airflow from interfering with each other within the arc-extinguishing assembly. This effectively reduces the residence time of the electric arc inside the circuit breaker. The first air guide wall between the arc-extinguishing assembly and the first air outlet, and the second air guide wall between the arc-extinguishing assembly and the second air outlet, play a role in precisely guiding the airflow. When an electric arc is generated, the air guide wall can guide the airflow in an orderly and uniform manner to the arc-extinguishing assembly, forming a stable and suitable airflow field around the arc-extinguishing grid. This airflow field helps to quickly remove the heat and plasma generated by the electric arc, accelerate the arc extinguishing process, improve the arc extinguishing efficiency, reduce the erosion of the internal components of the circuit breaker by the electric arc, and enhance the breaking capacity and reliability of the circuit breaker.

The application discloses an electrical protection device for a low-voltage circuit, comprising a protection shell, a double-contact assembly, a contact seat assembly, an arc blowing assembly and an arc extinguisher, in order to solve the technical problem that the general electrical protection device in the prior art has slow arc extinguishing speed, limited breaking capacity, and the contact is easy to be ablated and damaged when frequently breaking the arc, and lacks a mechanism for preventing misoperation after fault tripping, resulting in insufficient safety, the application designs the above-mentioned electrical protection device for a low-voltage circuit, the double-contact assembly is used for realizing isolation protection of the arc and the main contact, the arc blowing assembly and the arc extinguisher are used for accelerating the movement and extinguishing of the arc in a cooperative manner, and the self-locking mechanism is used for preventing misoperation after fault, so that the breaking performance and operation safety of the device are improved, and the stable operation of the low-voltage circuit system is ensured.

An arc extinguish chamber structure of a switch belongs to the technical field of low-voltage apparatuses. The arc extinguish chamber comprises a pair of side plates, a plurality of grid pieces arranged between the pair of side plates and a pair of gas generating pieces, the grid pieces are arranged at intervals, and the pair of gas generating pieces are respectively located at the lower edges of the grid pieces.
