Detailed implementation manners

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Please refer to Figures 1-4 , the present utility model provides an embodiment: a vertically-mounted fan filter unit includes a mounting seat 1, an outer shell 2, a ventilation assembly, a filter element 3, a fan 4, and a sliding assembly; an anchoring hole is provided on the mounting seat 1, and the mounting seat 1 is fixed to the building wall surface through anchor bolts. The front side of the mounting seat 1 is fixedly connected with the outer shell 2. A ventilation assembly is provided on the outer shell 2. A filter element 3 is provided inside the outer shell 2. A fan 4 is provided inside the outer shell 2 and is located behind the filter element 3. A sliding assembly for moving the filter element 3 is provided inside the outer shell 2. By adding a sliding assembly for changing the position of the filter element 3 to the existing vertically-mounted fan filter unit, the filter element 3 can be moved out of the fan filter unit by using the sliding assembly, which is convenient for replacing the filter element 3. The fan 4 is responsible for creating a pressure difference to suck external air into the fan filter unit, and the ventilation assembly can be used to achieve the clean self-circulation of the air inside the clean room.

[0026] Please refer to Figures 3-4, in this embodiment, the ventilation assembly includes a ventilation opening 501 and an air outlet 502. The ventilation opening 501 is provided on the front side of the outer shell 2, and the air outlets 502 are provided on both lower sides of the outer shell 2. A support plate 6 located in front of the air outlet 502 is fixedly connected to the inner side of the outer shell 2. The fan 4 is screwed to the front side of the support plate 6. A magnetic strip 7 is adhered to the outer shell 2 at the edge of the ventilation opening 501, and a filter screen 8 with an iron frame is magnetically connected to the front side of the magnetic strip 7. After the fan 4 is started, a pressure difference is formed between the inside and the outside of the fan filter unit. The outside air enters the fan filter unit through the ventilation opening 501, and after being filtered and purified, it is discharged from the air outlet 502. The fan 4 is installed on the support plate 6, which is convenient for disassembly when replacement or maintenance is needed. The effect of absorbing outside air is achieved by the high-speed rotating fan 4. The filter screen 8 is fixed to the front side of the ventilation opening 501 through the magnetic strip 7. This fixing method is convenient for disassembly, and at the same time, the filter screen 8 can trap dust and impurities with relatively large particles.

[0027] Please refer to Figures 5-6 , in this embodiment, the sliding assembly includes a storage groove 901 and a frame plate 902. The storage groove 901 is provided at the top of the outer shell 2 in front of the fan 4. A frame plate 902 is movably connected in the storage groove 901, and a filter element 3 is installed in the frame plate 902. The sliding assembly further includes a slide rail 903 and a slider 904. Slide rails 903 that are opposite to each other left and right and have sliding grooves on their surfaces are provided inside the outer shell 2. A slider 904 is slidably connected in the sliding groove, and the frame plate 902 is fixedly connected between the two sliders 904. A rubber sealing ring 10 that closely adheres to the edge of the frame plate 902 is provided between the frame plate 902 and the storage groove 901. A handle 11 is fixedly connected to the top of the frame plate 902. The filter element 3 is driven to move out of the fan filter unit through the frame plate 902, and the position of the filter element 3 in the storage groove 901 is changed by the up and down movement of the slider 904 in the sliding groove. The rubber sealing ring 10 can prevent air from leaking through the gap between the storage groove 901 and the frame plate 902 when the fan filter unit is working. The handle 11 facilitates the movement of the frame plate 902.

[0028] When working, first, the staff fixes the filter screen 8 to the front end of the ventilation opening 501 through the magnetic strip 7, then aligns the mounting seat 1 with the building wall surface, and then installs it. When it is necessary to purify the indoor air, the fan 4 is turned on. The high-speed rotation of the fan 4 generates suction, sucking the air outside the vertically installed fan filter unit along the ventilation opening 501. After the air contacts the filter screen 8 and the filter element 3, impurities, bacteria and other pollutants in the air are adsorbed on the filter element 3, and the purified air is discharged along the exhaust port, realizing the self-circulation cleaning of the air;

[0029] After the vertical installation type fan filter unit has been used for a period of time, a large amount of impurities and bacteria adhere to the filter element 3, which affects the air filtering efficiency of the fan filter unit. When the filter element 3 needs to be replaced, hold the handle 11 and pull the frame plate 902 upward. The slider 904 slides in the chute opened in the slide rail 903, driving the frame plate 902 to move upward. The filter element 3 installed in the frame plate 902 is removed from the housing 2 of the fan filter unit along with the frame plate 902. After replacing the filter element 3, hold the handle 11 and push downward. The slide rail 903 plays a role in guiding, preventing the new filter element 3 from shifting when moving downward until the rubber sealing ring 10 closely adheres to the inner wall of the receiving groove 901. The rubber sealing ring 10 plays a sealing role, preventing air from leaking through the receiving groove 901 during the cleaning of the air inside the clean room.

[0030] Through the above steps, a sliding component is added to the existing vertical installation type fan filter unit. The filter element 3 is installed on the sliding component, and the filter element 3 is removed from the vertical installation type fan filter unit through the sliding component. The filter element 3 can be quickly replaced without removing the entire vertical installation type fan filter unit, shortening the time for replacing the filter element 3 to solve the problem that the existing fan filter unit needs to spend a lot of time disassembling the entire fan filter unit before the filter element 3 can be replaced.
