The invention discloses an equipment host. The host comprises a host box body, a mounting cavity is formed in the host box body, a host mainboard is mounted on the bottom surface of the mounting cavity, a power-on key is arranged on the host mainboard, a mechanical self-locking button switch is adopted as the power-on key, and a heat dissipation device is fixedly mounted on the top surface of themounting cavity of the host box body. A first through hole is formed in the heat dissipation device from top to bottom in a penetrating mode, a second through hole is formed in the mainframe box bodyright opposite to the first through hole, a filtering rod penetrates through the first through hole and the second through hole, the bottom of the filtering rod makes contact with the top of the power-on key, and the filtering rod partially stretches out of the outer side face of the top of the mainframe box body. According to the equipment host, a traditional startup and shutdown key is hidden, an air inlet filter screen is omitted, the sealing performance and the waterproofness of the host box body are improved, the dust removal effect is improved, and filter screen holes are prevented frombeing blocked.

The invention discloses a soft-packed lithium manganese oxide battery with the function of preventing overcharging, and relates to the technical field of battery protection. The soft-packed lithium manganese oxide battery with overcharge prevention function includes a protective shell, and a partition plate is fixed at the bottom of the inner wall of the protective shell. The soft-packed lithium manganate battery with anti-overcharge function, during the charging process of the battery, the electromagnet composed of the wire and the iron core will control the position of the power-off mechanism, and at the same time the soft-packed lithium manganese battery block The temperature will rise. If there is an overcharge phenomenon, the temperature of the soft-packed lithium manganese oxide battery block will further increase. The increased temperature will cause the gas inside the thermal expansion airbag to be heated and expand. The thermal expansion airbag and the power-off mechanism will cause the wire switch to be closed. , and then the wire stops conducting conduction. At this time, the series connection between the two soft-packed lithium manganese oxide battery blocks is in an open circuit state, so charging cannot be continued, and the battery combustion and explosion caused by the continued overcharging of the battery are prevented.

The invention discloses a scroll compressor and a stationary scroll plate and upper cover assembly of the scroll compressor. The stationary scroll plate and upper cover assembly comprises a stationary scroll plate (1), an upper cover (20) and a pipeline connecting structure connected with the stationary scroll plate (1) and the upper cover (20). A through hole (201) which allows the pipeline connecting structure to penetrate through is formed in the upper cover (20). A stationary plate connecting hole (1a) connected with the pipeline connecting structure is formed in the stationary scroll plate (1). An anti-thrust structure (211) is arranged on the pipeline connecting structure. The through hole (201) is covered by the projection of the anti-thrust structure (211) towards the upper cover (20). The outer diameter of an upper pipe section (215), located on the anti-thrust structure (211) and far away from the stationary scroll plate (1), of the pipeline connecting structure is smaller than the inner diameter of the through hole (201). According to the stationary scroll plate and upper cover assembly, welding safety and reliability are guaranteed, the need of installation positional accuracy between the through hole (201) and the stationary plate connecting hole (1a) is reduced, production cost is reduced, and vibration of the pipeline connecting structure is reduced.

The invention discloses a combustible gas direct power machine, and belongs to the technical field of power machinery. The combustible gas direct power machine structurally comprises a combustion chamber, an air exchange system, a power output device and a sparking plug, wherein the air exchange system is arranged at one side of the combustion chamber; the sparking plug passes through the lateral wall of the combustion chamber; the power output device is connected with an outlet of the combustion chamber. The combustible gas generated by biomass can be directly converted into powder or electric power, and applied to industrial production.

The invention belongs to the technical field of vacuum pumps, and specifically relates to a diaphragm vacuum pump, which includes a housing, a cylinder and a protection box; a cavity is opened inside the housing; a cylinder is fixedly connected to the upper surface of the cavity; The output shaft of the cylinder is fixedly connected with a moving column, and the lower surface of the moving column is fixedly connected with a diaphragm; the right side of the cavity is provided with a protective box; the invention effectively solves the problem of the diaphragm vacuum pump directly vacuuming the device. At the same time, it is easy to suck the liquid or water vapor in the device into the diaphragm vacuum pump. At the same time, if the device is at a high temperature, directly extracting the hot air in the device will easily cause problems such as damage to the internal diaphragm of the diaphragm vacuum pump; effectively improved The service life of the diaphragm vacuum pump.

The high-efficiency detection device and detection method of benzene-based volatile organic components belong to the technical field of benzene-based volatile detection. In order to solve the problem of using a set of sampling equipment for multiple sampling, it is necessary to replace multiple sets of activated carbon sampling tubes intermittently. For The clamping of the activated carbon sampling tube and the need to disassemble and collect sections A and B after sampling is not convenient enough, and the connection between the activated carbon sampling tube and the exhaust mechanism is relatively inconvenient; the invention uses the umbrella on the top of the double-head motor The bevel gear meshes with the second meshing disc, and then under the action of the clamping assembly, the two sets of clamping blocks clamp the sampling tube, and the first telescopic cylinder is stretched out, so that the bevel gear at the bottom of the double-head motor meshes with the first meshing disc, under the clamping of the clamping assembly and the rotation of the limit shaft and the movable rod, the glass tubes of the two groups are separated. Groups of activated carbon adsorption blocks were disassembled and collected.
