The invention belongs to the technical field of chip testing, and particularly discloses a chip testing notch, a chip testing device and a chip testing system, and the chip testing notch, the chip testing device and the chip testing system are used for allowing a chip testing clamp to be inserted to test a chip. The test plate is arranged above the heating plate, a test station for accommodating the chip test clamp is formed between the test plate and the heating plate, and at least one reed is arranged at the position, opposite to the test station, of the test plate; wherein when the chip test fixture is placed at the test station, the reed is elastically crimped on a test contact on the upper surface of the chip test fixture. The chip test fixture can solve the problem that the probe is easy to damage when the current chip test fixture is plugged in and pulled out of the drawer, and is suitable for automatic aging test, so that the aging test efficiency is improved, and the safety and reliability of the test process are guaranteed.

The cleaning and recycling system comprises a vehicle cleaning platform and a garbage cleaning pool, a plurality of sewage recycling channels are formed in the vehicle cleaning platform at intervals, elastic filtering assemblies are arranged on the sewage recycling channels, and air injection channels communicating with the sewage recycling channels are formed in the vehicle cleaning platform; an air pump is arranged in the air injection channel, the garbage cleaning pool is located on one side of the vehicle cleaning platform, the bottom of the garbage cleaning pool communicates with the multiple sewage recycling channels, and the air pump is designed to inject air flow, push sewage in the sewage recycling channels to be injected into the bottom of the garbage cleaning pool and drive the elastic filtering assembly to vibrate at the same time. By adopting the scheme, the air flow generated by the air pump is used as a power source, so that cleaning sewage containing silt is sucked and injected to the bottom of the garbage cleaning pool to generate a disturbance effect on the bottom of the pool, the conditions of sludge hardening and sedimentation are reduced, and meanwhile, the disturbance effect in the garbage cleaning pool is beneficial to separation of large-density garbage and light garbage.

The invention discloses a double-cavity balance type piezoelectric valve which comprises a valve seat, a valve core, a pressure sensor, a first pressure sensor and a second pressure sensor. The piezoelectric valve plate is arranged in the cavity and divides the cavity into a first chamber and a second chamber, the first air outlet communicates with the first chamber so that the first chamber can exhaust air to the outside through the first air outlet, and the piezoelectric valve plate is suitable for deforming to control the first air outlet to be opened and closed; the air inlet flow channel comprises an air inlet, a first branch and a second branch, the first branch and the second branch are separated from the air inlet and are independent fluid channels, and after fluid of the air inlet is divided, the fluid enters the first cavity and the second cavity independently through the first branch and the second branch. Therefore, when no air flow is output from the first cavity and the second cavity, the air pressure in the first cavity and the air pressure in the second cavity are kept balanced, the valve plate does not need to additionally overcome pressure difference deformation, then the driving force needed for opening or closing the valve by the piezoelectric valve plate is reduced, and the response speed of the valve is higher.

The utility model discloses a kind of electric core and battery, wherein, electric core includes pole piece, diaphragm and true tab, multiple pole piece is laminated, the polarity of adjacent two pole pieces is opposite, and diaphragm is equipped between adjacent two pole pieces;Multiple pole pieces with same polarity include first pole piece and second pole piece, first pole piece has empty foil area, part structure of true tab is between first pole piece and adjacent diaphragm, true tab is connected with empty foil area, second pole piece has protruding false tab, and false tab is conductive connection with part structure of true tab exposed to first pole piece.The electric core of the utility model can integrate true tab to pole piece interlayer, realize fixed using pole piece itself structure, reduce invalid space.When external packaging force acts on true tab, force is conducted to the current collector of first pole piece by empty foil area, is dispersed and absorbed by entire pole piece structure, reduce the mechanical load of false tab and true tab welding point, to effectively avoid mechanical damage of welding position in packaging process.
