According to the silicon wafer cleaning device, through the arrangement of the hanging basket, the motor and the mounting column, after silicon wafers in the hanging basket are cleaned, the hanging basket is moved to the position near the mounting column through the moving mechanism, the hanging basket is clamped to the mounting column through the fixing rod, the motor is started, and the motor drives the hanging basket to rotate through the mounting column; when the hanging basket rotates, water in the hanging basket is discharged through the water discharging inclined opening under the action of centrifugal force, when the hanging basket rotates, the hanging basket drives outside air to enter the air groove formed in the hanging basket through the first air inlet and the second air inlet formed in the two sides, and airflow is discharged through the intercepting net to air the outer side of the silicon wafer.

The invention discloses a method for manufacturing blind grooves embedded in copper blocks of circuit boards, comprising the following steps: attaching a photosensitive resist film to one side of the circuit board where the copper blocks are embedded; The position is blocked, and the other positions of the photosensitive resist film are polymerized by light irradiation; the position of the photosensitive resist film corresponding to the copper block that needs to open a blind groove is removed by developing reaction, and the copper surface is exposed; the etching solution is sprayed on the copper surface to etch out Blind slot. By using the photosensitive resist film after polymerization to protect the part of the circuit board that does not need to open the blind slot, the depth of the blind slot can be well controlled by etching, and the uniformity of the etching is used to make the wall of the blind slot after etching flat, thereby solving the problem. It solves the problem of milling cutter printing on the bottom of blind slots traditionally processed by CNC machine tools, improves the heat dissipation effect of heating components in the later stage, and completely solves the problem of unclean cleaning of copper PCB surface cooling oil and coolant after milling slots.

The invention relates to a blue ink and concretely to a water pigment blue ink which is easy to wash and can be used in fountain pen and sign pen. The said ink solves the problem in present blue ink which is of poor water resistance and sun resistance and can not be washed easily. The weight ratio of raw materials composition of the prepared ink is: 1.0 % -5 % of Berlin blue colorant, 0.2 % - 5 % of oxalic acid complexing agent, 0.01 % - 2 % of surface activator, 1 % - 10 % of water-loss reducer , 0.1 % - 1 % of binding agent, 0.1 % - 1 % of preservative agent, and the other is water. In relation to the present technology, the significance effect of this invention is: 1. in relation to the present blue ink, it has good water resistance and sun resistance but small diffusibleness; 2. in relation to the present writing ink of all kinds, it is erasable which solves the problem that clothes can not be washed cleanly when contaminated by the present ink; 3. the said ink and its catabolite is nontoxic, flavourless and can not pollute the environment.

The invention belongs to the field of disinfection of food processing factories and particularly discloses an in-out-factory palm disinfection method for an aquatic product processing factory. Benzalkonium bromide and polyethylene oxide are mixed according to the volume ratio of (15-25):(1-1.5), clear water is added to the mixed solution for dilution to prepare a disinfectant, and the microorganism inhibition effect is improved. Meanwhile, a hand washing device for the aquatic product processing factory is used in the method, the disinfection cleaning effect is improved, and the situation is avoided that in the prior art, operation personnel cannot clean the two hands completely by themselves.

The invention discloses power-shaking-based and water-washing-combined circulating reciprocating type clam cleaning device and method. The device comprises a water tank, wherein the surface of the water tank is sleeved with a filtering device, fixing screws are arranged on the inner wall of the filtering device, the surfaces of the fixing screws are in threaded connection with the inner wall of the water tank, and supporting rods are connected to the upper surface of the water tank. The invention discloses a circulating reciprocating type concha cleaning device based on power shaking and combined water washing. Under the action of the connecting block, the shaking frame reciprocates and shakes front and back; then the push rod pushes the cleaning box to reciprocate back and forth, so thatthe force for shaking the nail is constant, the force for shaking the nail is prevented from being too large or too small, and therefore the problems that at present, in a hand cranking process, the force is difficult to control, the shell of the nail is prone to being broken due to the too large force, the amount of spit sediment is small due to the small force, and the interior of the nail cannot be cleaned thoroughly are effectively solved.

The invention relates to the technical field of stator inner cavity dust removal, in particular to a structure of a motor stator inner cavity dust removal device, which includes a fixed plate, a first through hole is opened in the middle of the fixed plate, and a first through hole is provided under the fixed plate. Holes connected to the dust suction head, the middle of the stator support plate is provided with a second through hole coaxial with the first through hole, the second through hole is provided with a column directly above, and the column is connected to the second through hole. The holes are arranged coaxially and supported on the stator support plate, the diameter of the cylinder is smaller than the diameter of the second through hole, the outer diameter of the cylinder is slightly smaller than the inner wall of the stator, a cylindrical air cavity is opened inside the cylinder, and the cylinder The upper part is circumferentially opened with several air outlet holes communicating with the cylindrical air cavity. This structure solves the problem that the dust and debris in the inner cavity of the stator cannot be cleaned cleanly when using the existing structure for dust removal, reduces the defect rate of friction noise of the motor, improves product quality and improves customer satisfaction.

The embodiment of the present invention discloses a method for controlling a food processor. The food processor may include a crushing cup, a heating device, a motor, and a temperature sensor. The temperature of the inner wall; when it is detected that the temperature of the inner wall of the crushing cup is less than or equal to the preset first temperature threshold T1, the heating device is controlled to heat with a preset power, so as to maintain the temperature of the inner wall of the crushing cup when the crushing cup is discharged Always greater than or equal to the preset second temperature threshold T2; wherein, the first temperature threshold T1 is greater than the second temperature threshold T2; the second temperature threshold T2 is greater than or equal to 60°C. Through the solution of this embodiment, the temperature of the inner wall of the crushing cup is kept at least above 60° C., which solves the problem of food sticking on the food processing cup and improves the cleaning effect.
