The invention discloses an air inlet and dust discharge device for an air filter, the air filter with the air inlet and dust discharge device and a micro-cultivator with the air filter. The air inletand dust discharge device for the air filter comprises an upper shell and a waterproof cover, wherein the upper shell is of a column-shaped structure with an opening in the upper end, the waterproof cover covers the opening, a dust discharging opening is formed at the position, close to the opening in the upper shell, of the side wall of the upper shell, a plurality of air inlets are formed in thebottom surface of the upper shell, are uniformly distributed in an annular array along the outer edge of the circumference of the bottom surface, and are provided with flow guide plates, the flow guide plates are inclined towards the interior of the upper shell in the circumferential direction, acute angles are formed between the flow guide plates and the bottom surface of the upper shell, and the inclination angles of all the flow guide plates are the same. Air with dust enters from the air inlets and is guided by the flow guide plates to form cyclone to rotationally rise in the upper shell,the dust can be discharged out of the upper shell when rotating to the dust discharging opening, the air subjected to primary dust discharging enters a filter device, so that the pressure of the filter device is reduced, and the performance of the air filter is further improved.

The invention discloses an automotive frame fold straightening machine which comprises a car body, a wire cable, a stand column, a clump weight, a swinging strut, an adjusting oil cylinder, a front fixed pulley and a rear fixed pulley. The automotive frame fold straightening machine further comprises an omnibearing rotation straightening device which can rotate 360 degrees in the horizontal direction and the vertical direction, a remote control receiver which is installed in the car body and used for controlling the omnibearing rotation straightening device, and a motor oil pump set which provides power for the omnibearing rotation straightening device through an oil pipe. The motor oil pump set is electrically connected with the remote control receiver. The omnibearing rotation straightening device is connected with one end of the wire cable through the front fixed pulley. The other end of the wire cable is connected with the clump weight through the rear fixed pulley. A holding frame used for stabilizing the omnibearing rotation straightening device is connected to the front end of the car body. By means of the automotive frame fold straightening machine, an automotive frame can be straightened at any position, as a result, repair difficulty is reduced, and repair efficiency is improved; since the omnibearing rotation straightening device is controlled remotely, the workload of manual intervention is small, and safety performance is higher.

The invention discloses a photoresist recovering system which is used for solving the problems that the used photoresist exhausted from a photoresist coating machine is wasted. The system comprises a receiving device which is connected with the photoresist coating device, and a conveying device connected with a first buffer device and a second buffer device, respectively, and is used for conveying the photoresist in the first buffer device into the second buffer device, wherein the top of the second buffer device is connected with a dry and clean air source via a pipeline which is provided with a second control valve; the bottom of the second buffer device is connected with a pipeline which is provided with a fourth control valve; the second buffer device is used for containing the used photoresist conveyed by the conveying device and conveying the used photoresist to a photoresist barrel via the pipeline provided with the fourth control valve under the air pressure provided by the dry and clean air source. The used photoresist exhausted from the photoresist coating machine enters the photoresist barrel via the devices, in this way, the photoresist can be recycled, and consequently, the production cost is reduced.

The utility model discloses a gas water boiler and is capable of effectively solving the problems of inconvenient arrangement of burners and wasting time and energy of the prior gas water boiler. The gas water boiler comprises a burner and a base plate, wherein the burner is fixed on the base plate, a plurality of air holes are formed on the base plate, fixing holes are formed at the rim of the base plate to fix the frame of the gas water boiler. The gas water boiler has the advantages that the burner is fixed on the base plate, and then the frame of the gas water boiler is fixed on the base plate, thereby greatly decreasing installation difficulty, improving installation efficiency, and simultaneously, the air holes enable to ensure enough oxygen gas to enter the burner.

The invention discloses a sofa sucking device which comprises a body and a suction tube.
