Detailed Description

In order to make the objects, aspects and advantages of the technical solution of the present invention more clear, the technical solution of the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiment of the present invention.

Example 1

Please refer to fig. 1 to 9: the invention provides an air disinfection purifier (also called as a purifier for short) with a filtering structure convenient to replace, which comprises an outer machine body 1, wherein the top of the outer machine body 1 is an opening side, a magnetic switch (for example, the magnetic switch is a reed pipe and a Hall switch) and an assembly top cover 108 with a magnet are arranged on the opening side, the assembly top cover 108 is fixed on the opening side by utilizing a magnetic attraction, and the assembly top cover 108 is provided with an air suction port and a filter screen 1081 fixed on the air suction port so as to filter sundries with larger size contained in external air entering the outer machine body 1 through the filter screen 1081; the two opposite vertical sides of the outer machine body 1 are provided with air outlets and air control fan strips 7 assembled at the air outlets, for example, eight groups of air control fan strips 7 with diamond-shaped sections are respectively and rotatably arranged at each air outlet as shown in the drawing, and the edges of the eight groups of air control fan strips 7 can be attached. The assembly top cover 108 fixed by magnetic attraction is arranged at the top of the outer machine body 1 so as to facilitate the opening of the assembly top cover 108, and the open side of the top of the outer machine body 1 is thoroughly opened into a larger operation space after the assembly top cover 108 is opened, thereby facilitating the assembly and the later maintenance of the inside of the purifier.

The driving device is arranged in the outer machine body 1 and comprises a middle frame 2 positioned below the air suction port, a motor 304 and a control circuit board 102, wherein the motor 304 is vertically fixed in the middle frame 2 and is connected with the magnetic induction switch in series. The middle frame 2 separates the driving device from the purifying air channel between the air inlet and the air outlet, so that on one hand, the air in the purifying air channel cannot enter the middle frame 2 to reduce the purifying efficiency of the purifier, and on the other hand, the middle frame 2 is used for isolating the noise generated by the operation of the motor 304 to reduce the working noise of the purifier; meanwhile, the motor 304 is vertically arranged and fixed in the middle frame 2, so that the motor 304 is conveniently connected with a fan in an air inlet above the motor 304 in a transmission manner, and a heat dissipation scheme is also conveniently designed for the motor 304.

Two groups of air duct bottom plates 4 are arranged in the outer machine body 1, and the air duct bottom plates 4 extend downwards from the top of the middle rack 2 towards the air outlet in a tilting manner, so that the top of the air duct bottom plates 4 is lower than the top of the middle rack 2; a mounting table 41 (see fig. 5) is provided at the top end of each duct floor 4 to facilitate assembly of the filter structure. Specifically, the mount 41 is provided with a plug-in clip 401, and a plug-in groove is formed between the plug-in clip 401 and the end side of the intermediate frame 2.

Therefore, the air duct bottom plate and the inner wall of the outer machine body 1 enclose and form a purification air duct between the air inlet and the air outlet, and the air duct bottom plate 4 is downwards inclined to extend so as to enable the purifier to form a structure with top air inlet and two opposite vertical side air outlets, and after the external air enters the purification air duct, the external air can be rapidly guided to the air outlet through the downwards inclined air duct bottom plate 4, so that the air can smoothly flow in the purification air duct, and the air purification efficiency of the purifier is improved.

A filtering structure is arranged in the purification air duct and is fixed on a mounting table 41 at the top end of the air duct bottom plate 4; the filter structure comprises at least a filter 403 and a negative ion generator 404.

When the inclination angle of the two is smaller than 45 degrees or larger than 75 degrees, the filter 403 is easy to be overturned by the air flow entering the purifying air channel to topple over, the air inlet surface of the filter 403 facing the air inlet and the front area of the air inlet are reduced, the effective filtering area of the filter 403 facing the air inlet surface of the air inlet is reduced, and the filtering and purifying performances of the filter 403 are affected.

An elastic bolt 402 with a spring is fixed at the edge of the mounting table 41, and the elastic bolt 402 is obliquely arranged upwards; correspondingly, a locking hole is arranged on the leeward surface of the filter 403, and the locking hole is higher than the plug-in clamping strip 401, so that a supporting point is generated on the leeward surface of the filter 403 higher than the top end of the plug-in clamping strip 401; the end of the elastic latch 402 is inserted into the locking hole to fix the filter 403 on the mounting table and provide anti-toppling support from the leeward side of the filter 403, so that the filter 403 is firmly assembled and is not easy to shift to maintain efficient filtration and purification performance.

The purifier disclosed by the invention has the characteristics that the filtering structure is convenient to replace: when the filtering structure needs to be replaced or cleaned, the assembly top cover 108 is directly opened manually, so that the opening side of the outer machine body 1 is exposed to provide a larger operation space; meanwhile, after the assembly top cover 108 is taken down, the magnetic induction switch is disconnected, so that the motor 304 and the air exhaust fan 5 stop working, and the use safety is ensured; then the elastic bolt 402 is pulled to withdraw from the locking hole of the filter 403, and then the lower end of the filter 403 is pulled out from the inserting groove to be replaced and cleaned, so that the filter has the advantages of convenient operation, safe use and the like.
