DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-10 A fresh air air purifier and disinfector comprises an air purifier and disinfector body 1, which has an air inlet and an air outlet, wherein a metal primary filter 2, a gas phase filter module 3 and a HEPA filter 4 are sequentially plugged into the side along the direction from the air inlet to the air outlet, and handles are arranged on the three upper sides for easy disassembly. The metal primary filter 2 is made of a metal stainless steel wire mesh woven into a micro-pore metal wire mesh to capture large-diameter particles, hair, etc. in the air, and has strong corrosion resistance and aging resistance. When it is found that the primary filter is full of dust and hair, it should be cleaned in time, dried and loaded into the machine for continued use. The primary filter is a washable filter mesh, and there is no need to replace this consumable. It is usually cleaned once every 1-2 months. The gas phase filter medium filled in the gas phase filter module 3 is a chemical adsorbent, which is mainly used to improve indoor air quality. It is a specially designed filter material with excellent performance in controlling the growth of bacteria and fungi, and can remove a variety of gaseous pollutants in the airflow, such as NO2, SO2, O3 and volatile organic compounds, as well as some low molecular weight compounds such as aldehydes and hydrocarbons. When replacing the gas phase filter module, you need to wear a mask and gloves. The HEPA filter 4 is made of H13 grade air filter material, with a filtration efficiency of up to 99.97%, low resistance and high efficiency, large dust holding capacity, and long service life. The HEPA filter usually needs to be replaced every 6 months. A junction box 17 is arranged on the side of the air outlet of the air purifier disinfector body 1, and an inspection cover 8 for covering the metal primary filter 2, the gas phase filter module 3 and the HEPA filter 4 is arranged on the side of the air purifier disinfector body 1. After opening, it is used to disassemble or repair the internal parts. At this time, the inspection cover 8 is flipped to a horizontal position. In this position, the hanging bracket mechanism can be dropped to hang the metal primary filter 2, the gas phase filter module 3 or the HEPA filter 4, which are collectively referred to as filters hereinafter. You can hang whichever one you want to repair without affecting the disassembly of other filters.

[0032] Specifically, the side surfaces of the air purification and disinfection machine body 1 are symmetrically fixedly connected with a mounting support mechanism for supporting the inspection cover 8 in a horizontal position to ensure the stability of the filter rack.

[0033] Specifically, the mounting support mechanism includes a mounting rod 7 symmetrically fixedly connected to the side of the air purification and disinfection machine body 1 and a two-link assembly slidably connected to the mounting rod 7. One end of the two-link assembly away from the mounting rod 7 is rotatably connected to the end of the inspection cover 8 away from the mounting rod 7. The two-link assembly can form a certain angle for supporting the inspection cover 8.

[0034] Specifically, in order to facilitate installation and storage, a slide groove 18 is opened on the side of the installation rod 7, and a matching groove 27 is opened on the bottom. A slider 19 is slidably connected in the slide groove 18, and the slider 19 is slidably connected in the slide groove 18 on the side of the installation rod 7 away from the inspection cover 8.

[0035] Specifically, the two-link assembly includes a first support rod 20 rotatably connected to the slider 19, a second support rod 21 rotatably connected to one side of the first support rod 20, a limit block 22 fixedly connected to the second support rod 21 toward the side of the air purification and disinfection machine body 1, and a connecting mechanism movably arranged at an end of the second support rod 21 away from the first support rod 20, which is used to connect the inspection cover 8. The limit block 22 can be set according to the situation. For example, when the first support rod 20 and the second support rod 21 are required to be completely parallel, the limit block 22 can be set as a straight plate. When a certain angle is required, a corresponding special-shaped mechanism can be set according to the angle. When the first support rod 20 and the second support rod 21 are folded, they can be just stored in the mounting rod 7. At this time, the end of the second support rod 21 away from the first support rod 20 can be inserted into the matching groove 27, so that this end is connected to the inspection cover 8.

[0036] Specifically, in order to facilitate the installation of the filter, a positioning rod 5 is fixedly connected to the lower end of the filter, and a positioning groove 6 for the positioning rod 5 to be inserted is opened at the bottom of the air purification and disinfection machine body 1 to realize the positioning of the filter. A straight plate 13 is symmetrically fixedly connected to the upper end of the filter, and a second support plate 14 and a first support plate 15 are fixedly connected to the middle of the opposite side of the straight plate 13 and the end facing the inspection cover 8 respectively. The positions of the second support plate 14 and the first support plate 15 are convenient for the straight plate 13 to form a structure with an inverted L-shaped groove 12 in the longitudinal section.

[0037] Specifically, the hanging mechanism includes a T-slot 9 opened in the inspection cover 8, a T-plate 10 slidably connected to the T-slot 9, and a hanging plate 11 fixedly connected to the lower end of the T-plate 10. The lower end of the hanging plate 11 is symmetrically provided with multiple groups of hanging grooves for hanging the second support plate 14 and the first support plate 15. Each group of hanging grooves consists of two symmetrically arranged and inverted L-shaped grooves 12. When the inspection cover 8 is horizontal, it is also horizontal with the filter. The first support plate 15 on the filter can be directly inserted into the hanging groove by directly pulling the handle 16. As the pull continues, the second support plate 14 can be inserted into the hanging groove. At this time, the filter has been removed from the air purification and disinfection machine body 1, and the filter can be hung on the hanging plate 11 for inspection and maintenance of the filter.

[0038] Specifically, the end of the inspection cover 8 away from the air purifier and disinfector body 1 is slidably connected with a plug plate 33, and the end of the T-slot 9 away from the air purifier and disinfector body 1 is connected to an avoidance groove 35, that is, it avoids the trajectory of the up and down movement of the T-plate 10 to prevent interference. The lower end of the plug plate 33 located in the T-slot 9 is fixedly connected to the limiting strip 34, which can prevent the plug plate 33 from falling. When the hanging plate 11 fits the inspection cover 8, the plug plate 33 can be inserted into the T-slot 9 and the upper end surface of the plug plate 33 fits the lower end surface of the cross plate of the T-plate 10. After insertion, the end of the plug plate 33 away from the limiting strip 34 can be adsorbed in the recessed groove 36 opened on the inspection cover 8 to prevent the plug plate 33 from detaching from the T-slot 9. This situation is suitable for inspection and maintenance of the filter without hanging, and is also suitable for the scene where the hanging plate 11 is retracted when the inspection cover 8 is closed.

[0039] Specifically, the connecting mechanism includes a first plug rod 23 inserted in the end of the second support rod 21 away from the first support rod 20, a second baffle 25 and a first baffle 24 fixedly connected to the middle and one end of the first plug rod 23, the second support rod 21 is located between the second baffle 25 and the first baffle 24, and the first plug rod 23 fixed with the first baffle 24 is inserted in the inspection cover 8 to realize the detachable connection between the second support rod 21 and the inspection cover 8, and the first plug rod 23 will not fall off from the second support rod 21.

[0040] Specifically, the lower end of the mounting rod 7 is fixedly connected with a mounting plate 28, a polygonal rod 29 is slidably connected in the mounting plate 28, the middle part and one end of the polygonal rod 29 are respectively fixedly connected with a fourth baffle 31 and a third baffle 30, the mounting plate 28 is located between the fourth baffle 31 and the third baffle 30, a spring 32 is fixedly connected between the fourth baffle 31 and the mounting plate 28, and a polygonal groove 26 for inserting the polygonal rod 29 is provided in the middle part of the first baffle 24, so that the first plug 23 is pressed against the side of the inspection cover 8. When the inspection cover 8 is closed, the polygonal rod 29 presses against the first plug 23, so that the inspection cover 8 can be temporarily fixed to the side of the air purification and disinfection machine body 1 to prevent the filter from sliding out.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims.
