A volute of a traditional range hood is positioned on the interior of a shell or the upward side of the interior of the shell, and greases are seriously accumulated on the shell and a volute component, thus cleaning is troublesome, the greases in the lampblack are difficult to filter, and the lampblack suction effect is poor. The range hood provided by the invention comprises a smoke inlet box and a blower component, and is characterized in that the smoke inlet box comprises a front plate and a rear plate, and a vertical smoke inlet chamber is formed in the smoke inlet box; the smoke inlet chamber is located between the front plate and the rear plate and opened upwards, a smoke inlet communicated with the smoke inlet chamber is formed on the lower end of the front plate, the outer side of the front plate is provided with a rotation panel which can open or close the smoke inlet, a smoke collection box is arranged above the smoke inlet box, a smoke collection chamber communicated with the upper port of the smoke inlet chamber is formed in the smoke collection box, the blower component is vertically arranged on the one side of the smoke collection chamber, and comprises an air inlet and an air outlet, and the air inlet is communicated with the smoke collection chamber. The range hood provided by the technical scheme has a good effect on filtrating greases, thus generating less influence on the blower component; and the discharge is environmentally-friendly, the efficiency of lampblack discharge is high, and the volume is small.

The invention discloses an active feeding hopper and a feeding method. The active feeding hopper is characterized by comprising a stock bin, a material collecting rotating wheel and a first driving mechanism; the stock bin comprises a blanking area, a material collecting area and an inclined plane, the blanking area is higher than the material collecting area, and the inclined plane is connected with the blanking area and the material collecting area; the material collecting rotating wheel is connected with the stock bin at a vertical or inclined set angle and is connected with a first drivingmechanism; a lower edge of a circumferential wall of the material collecting rotating wheel is arranged in the material collecting area and connected with a lowest edge of a slope; and a plurality ofblades are arranged on the circumferential wall of the material collecting rotating wheel. The active feeding hopper and the feeding method have the advantages of being compact in structure, stable in operation and high in working efficiency.

The invention discloses an ambroxol hydrochloride solution for inhalation, which is characterized in that: every 100mL of solvent contains 0.15-0.3g of ambroxol hydrochloride, a surfactant whose mass is 4-6% of ambroxol hydrochloride and an appropriate amount of antioxidant and preservatives, the pH value of the solution is 4.6-5.8, wherein the solvent is selected from water for injection, physiological saline, and isotonic glucose solution. The ambroxol hydrochloride solution for inhalation of the present invention is sprayed into the oral cavity of a patient to form an aerosol, which directly enters the respiratory tract, has a high inhalation rate and a high local concentration, achieves safe and targeted treatment purposes, and effectively promotes the discharge of sputum in patients. The dosage is small, the drug effect is high, and the safety and stability are good, it is not easy to be polluted or oxidized and deteriorated, and the storage time is long.

The invention discloses a device for feeding a rod with a lifting head. The device comprises a hopper, a rotating disc and a driving mechanism, wherein a rotating shaft for connecting the rotating disc and the driving mechanism is arranged on the mounting plate of the hopper; the mounting plate is provided with an annular sealing ring on the inner side of the hopper; an arc-shaped groove is formedin the bottom of the annular sealing ring; gas sucking holes are formed in the arc-shaped groove and the mounting plate in a communicating manner; a confirmation gas sucking hole is formed in the topof the annular sealing ring; material sucking holes communicated with the gas sucking holes and the confirmation gas sucking hole in a one to one correspondence manner are formed in the rotating disc. The device is characterized in that a shifting groove is formed in the rotating disc; the material sucking holes are stepped holes; the gas sucking holes and the confirmation gas sucking hole are connected with a gas source pipeline; the driving mechanism is a geneva wheel driving mechanism of which the center distance can be adjusted; the gas source pipeline and the driving mechanism are electrically connected with a control unit; a shifting mechanism is arranged inside the hopper. The device has the advantages that a plurality types of rods with lifting heads can be fed into the material sucking holes with a high probability at correct postures, are retained in the material sucking holes, and are further accurately positioned and conveyed to a discharge position.

The invention provides a high-performance mesh atomizer, which belongs to the field of medical devices. The high-performance mesh atomizer includes a liquid medicine tank (1), and a liquid medicine cover (5) for closing the liquid medicine tank (1). ), mask connector (2), isolation plate, mist storage tank (3) and the base (4) detachably connected to the bottom of the mist storage tank (3), the liquid medicine tank (1) and the mask joint (2) Set on the isolation plate and detachably connected with the storage tank (3) through the isolation plate, the liquid medicine tank (1) can form the liquid medicine into liquid particles with MMAD value less than 5 μm and input them The spacer tank body (3) is inhaled by the patient through the mask connector (2). The high-performance mesh nebulizer provided by the invention is an atomization inhalation device suitable for atomization inhalation of children and adults. The device has the characteristics of high atomization inhalation rate, low working noise, low use cost, and high convenience.

The invention relates to an upward air intake burner, which includes an outer ring ejector tube, and is characterized in that: the outer ring ejector tube includes at least two sub-injection tubes, and the gas outlet of the upstream sub-injection tube is end stretches into the gas inlet end of the downstream sub-extractor tube, and the length of the downstream sub-extractor tube is greater than the length of the upstream sub-extractor tube adjacent to it. Compared with the prior art, The advantage of the present invention is that the outer ring injection pipe of the upward air inlet burner is composed of at least two sub-injection pipes in communication, which can improve the injection ability and prevent the gas and primary air from colliding in different directions and collide with each other, further improving Improve the uniformity of primary air and gas mixing and increase the primary air intake rate to effectively reduce kinetic energy loss and make it spread evenly, so that the flame of the upward air burner is short, uniform and powerful, and there will be no yellow flames, tempering, etc. defect.
