[0018] The beneficial effects of the present invention are:

[0019] The beneficial effect of the rotary drum wind wheel silent air dust purifier with a detachable and washable heat-increasing sterilizing filter described in the improvement of the present invention is that the lower end of the rotary drum wind wheel described in this scheme is inserted through the upper end of the shaft body of the base shaft body integrated air duct, the thrust bearing at the lower end of the rotary drum wind wheel is connected to the upper end of the shaft neck ring installed at the lower end of the shaft body, the motor is installed into the motor position at the bottom end of the base shaft body integrated air duct, the shaft head of the motor is extended out of the shaft hole of the motor position, and the shaft head is configured The 40mm driving gear is meshed with the 200mm gear ring at the bottom of the rotary drum wind wheel, the heat source electric pile is embedded in the lower end of the shaft of the base shaft body integrated air duct, and the motor plug is connected, the dust filter 4 is inserted downward from the upper end of the shaft of the base shaft body integrated air duct into the base plane of the base shaft body integrated air duct, and the dust filter 3 is inserted downward from the upper end of the shaft of the base shaft body integrated air duct. On the base plane of the base-shaft integrated air duct, the dust filter net 2 is also inserted from the upper end of the base-shaft integrated air duct downwardly into the base plane of the base-shaft integrated air duct, and then the dust filter net 1 is inserted from the upper end of the base-shaft integrated air duct downwardly into the base plane positioning circle of the base-shaft integrated air duct, and then the dust filter cylinder is inserted from the upper end of the base-shaft integrated air duct downwardly into the base-shaft integrated air duct. The outer side of the base plane positioning ring of the air duct, and then straighten the flat folded edges of each dust filter to form a support with a distance from each other, and put the cover from the upper end of the base shaft body integrated air duct downward into the shaft body of the base shaft body integrated air duct, and the asbestos gasket set in the cover seals the space at the upper end of each dust filter, and the outer edge of the cover covers the upper edge of the dust filter cylinder, and then the fastening ring is inserted from the upper end of the cover.Connect downward and screw into the gong-shaped body set on the outer side of the upper end of the base shaft body to tighten and rivet the cover and the dust filter at the lower end of the cover, then connect the heating electric plate together with the bracket from the upper end of the base shaft body integrated air duct to the air duct of the shaft body, then insert the two sets of electric heating plate plugs at the bottom of the heating electric plate bracket into the jacks of the heat source electric pile at the bottom of the shaft body, and the heating sterilization filter net is detachable and washable rotary wind wheel silent air dust purifier is assembled and connected. At this time, a certain amount of water is injected into the base counterweight to enhance its stability. After connecting to the power supply, start the motor first, and the potential energy of the motor operation is passed The driving gear through the shaft neck reduces the kinetic energy speed to less than 1000 revolutions per minute with a wheel speed ratio of 1:5, driving the drum-type wind wheel to rotate at medium and low speeds. The special design of the base shaft body integrated air duct described in the improved scheme provides a larger volume space for the drum-type wind wheel design. The large-volume drum-type wind wheel runs at medium and low speeds, reducing the impact friction of high-speed operation on the air and also reducing the generation of noise. Moreover, the large-volume drum-type wind wheel runs at medium and low speeds. Due to the volume effect, it can still obtain a larger rotary cutting gas and the function of air drainage. The drum-type wind wheel described in the improved scheme.The inner space designed in the layers of dust filters can not only rotate and drain the gas in the dust filters at a close distance, but also the drained gas and the fine mesh in the dust filters are helpful to absorb the noise generated during the rotation of the rotary fan wheel. Moreover, the layers of dust filters are also a barrier to the transmission of the operating noise of the rotary fan wheel. In the improvement of this scheme, a thick and extended shaft is used as a support body for the rotary fan wheel, and as a flow channel for the gas after dust purification. In addition, a heating electric plate is set in the channel for the dust-filtered gas arranged in the shaft body. It is not only a reasonable use of space, but also a technical solution to the additional function of the dust purifier, so that the general air purifier has a wider range of use than the original cognition and function. The rotary fan silent air dust purifier with a detachable and washable heating and sterilization filter extends the original air dust purification to the use of space to add an electric heating plate, and performs special heating and sterilization treatment on the gas in special periods and special environments, such as during epidemics and influenza outbreaks, or in special medical environments. This The gas in such an environment contains not only a lot of unknown floating gases, but also condensed droplets of suspicious respiratory gases, which cannot be eliminated by simply filtering dust and purifying. The heat-increasing sterilization function of the present invention can eliminate the droplets, gels and viruses and bacteria that may exist in the gas after dust purification. Because the gas after dust purification passes through the heating network with a heating plate in the gas channel, the suspicious substances contained in the gas will be changed by high temperature and heat. The dust filter 1 described in this technology, Dust filter 2, dust filter 3, and dust filter 4 are made of stainless steel with different meshes stacked one on top of the other. The dust filter meshes are evenly distributed around the circumference, which can be 360° around the body, and can absorb and filter dust in a wide range. They are also easy to disassemble and clean. When disassembling and cleaning is required, first disconnect the power system, unscrew the fastening ring at the upper end, remove the gong pattern rivet at the upper end, and remove the upper cover. Then, the dust filter cylinder, dust filter 1, dust filter 2, dust filter 3, and dust filter 4 can be removed one by one, and rinsed with clean water. Description of the drawings:

4. The heating plate according to claim 1 is composed of two groups of long strip heating plates with independent heating effect. The voltage of the heating plate is 220V and the current of the individual heating plate is 1000W. The two groups of heating plates are assembled in a heating plate bracket so that the two groups of heating plates and the bracket form a fixed body, which is convenient for use and installation. The bottom of the heating plate bracket is respectively provided with cylindrical plugs of the two groups of heating plates. The diameter of the heating plate bracket is 120mm and the length of the bracket is 1000mm. A heating net is set on the outside of the electric heating plate bracket. The heating net is made of stainless steel sheet material and is made into a cylinder with a diameter of 120mm and a length of 1000mm. The circumference of the cylinder is set into countless fine meshes. The function of the heating net is to absorb the heat emitted by the electric heating plate and block excessive heat radiation on the shaft of the base shaft integrated air duct. The gas after dust filtration by the filter screen is sucked by the rotary drum wind wheel. After entering the air duct, it is evenly heated and sterilized, and it can also play a role in silencing and reducing noise.
