Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an air purification fresh air fan. Background Art

[0002] An air purifier is a common air purification device. Its functions are roughly as follows: it can exhaust the polluted air in the room to the outside, and then input the fresh air from the outside into the room after sterilization, disinfection, filtration and other measures, so that the room is filled with fresh and clean air at all times.

[0003] Air purification includes filtration, disinfection and sterilization. Filtration requires a filter mechanism, which needs to be cleaned or replaced after a period of use. Since the air outlet and air inlet of some air purifiers are connected to the pipe, if the filter mechanism is set in the air outlet and air inlet, the pipe needs to be removed before taking it out. If the filter mechanism is set inside the device, the outer shell of the device needs to be opened, and then the filter mechanism needs to be removed in the narrow space of the device, which makes it inconvenient to replace the filter mechanism.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 The utility model discloses an air purifying fresh air fan, including a fresh air fan main body 10, which can filter, disinfect and sterilize dust or germs in the air (the current sterilization and disinfection of fresh air fans usually adopts ultraviolet disinfection and ion disinfection), so as to have a good air purification effect. The top surface of the fresh air fan main body 10 is provided with an air outlet 20 to discharge air (purified), and the bottom end of the fresh air fan main body 10 is provided with an air inlet 30 to take in air (unpurified). The front of the fresh air fan main body 10 is provided with a long groove 40, and a fastening mechanism 50 is provided in the long groove 40. The upper and lower ends of the fastening mechanism 50 are fixedly connected with a limited pressure piece 60, and a plurality of circumferentially distributed mounting holes 90 are provided on the side away from each other of the upper and lower limit pressure pieces 60, which can be fixedly connected with the telescopic mechanism 70. The air outlet 20 and the air outlet 20 are filled with a filtering mechanism 80, and the limiting pressure piece 60 is attached to the filtering mechanism 80, and the two limiting pressure pieces 60 are provided with a telescopic mechanism 70 on the side away from each other.

[0024] Specifically, four mounting plates 100 are welded to the back of the fresh air fan body 10, and each mounting plate 100 is an L-shaped structure.

[0025] In this implementation, the entire air purification fresh air fan is fixedly installed.

[0026] Specifically, the telescopic mechanism 70 includes a bellows 71 , and the upper and lower ends of the bellows 71 are fixedly connected with connecting flanges 72 , and one of the connecting flanges 72 is fixedly installed on the limiting pressing piece 60 by bolts.

[0027] In this embodiment, since the bellows 71 is retractable, when the limiting pressing piece 60 moves, the bellows 71 retracts and contracts, and will not interfere with the connected pipes (both hard pipes and soft pipes are acceptable, and have a wide range of applications).

[0028] Specifically, the fastening mechanism 50 includes a bidirectional screw 51 rotatably connected to the upper and lower inner walls of the long groove 40, the bidirectional screw 51 is threadedly connected to a pair of sliders 52, the thread directions of the two sliders 52 are opposite, the sliders 52 are connected to the long groove 40 for vertical sliding, and a pair of connecting rods 53 are welded on the sides of the two sliders 52 that are away from each other, the connecting rods 53 are welded to the limiting pressure plate 60, and a knob 54 is welded to the middle of the bidirectional screw 51.

[0029] In this embodiment, the reverse knob 54 reverses the bidirectional screw 51, and the upper and lower sliders 52 move away from each other. Under the connection of the connecting rod 53, the upper and lower limit pressing plates 60 move away from each other. Similarly, the forward rotation knob 54 causes the upper and lower limit pressing plates 60 to move toward each other, thereby quickly fixing and removing the filter mechanism 80.

[0030] Specifically, the air outlet 20 and the air inlet 30 are both horn structures, and the air outlet 20 and the air inlet 30 are fixedly connected to the fresh air machine body 10 by bolts.

[0031] In this embodiment, the shapes of the air outlet 20 and the air inlet 30 are introduced. The setting of this shape can improve the embedding tightness of the filter mechanism 80, and the bolts are fixed to make the connection firm and have the function of disassembly and assembly, so that it can be replaced.

[0032] Specifically, the filtering mechanism 80 includes a reinforcement ring 81, in which a filter screen 82 fixedly connected to the inner wall thereof is embedded, and a connecting shell 83 threadedly connected to the limiting pressing plate 60 is provided on the side of the reinforcement ring 81 away from the limiting pressing plate 60, and a filter element 84 is embedded in the connecting shell 83, and a plurality of storage grooves 85 are provided on a side of the filter element 84 close to the filter screen 82, and a plurality of desiccant particles 86 are placed in each storage groove 85, and the diameter of the desiccant particles 86 is larger than the filter hole diameter of the filter screen 82.

[0033] In this embodiment, the air is filtered to achieve rough purification of the air. Meanwhile, the desiccant particles 86 can also play a good drying role, thereby preventing the filter mechanism 80 from being damp and ensuring the filtering effect of the filter mechanism 80.

[0034] Specifically, two positioning protrusions 200 are integrally connected to the sides of the upper and lower limiting pressure plates 60 that are close to each other, and a pair of positioning circular grooves 300 are opened on the sides of the upper and lower reinforcement rings 81 that are away from each other, and the positioning protrusions 200 are clamped in the positioning circular grooves 300.

[0035] In this embodiment, when the filter mechanism 80 needs to be embedded in the air inlet 30, since the air inlet 30 faces downward, the filter mechanism 80 can be snapped onto the positioning protrusion 200 on the lower limiting pressure plate 60 in advance, thereby facilitating the subsequent stable embedding of the filter mechanism 80 in the air inlet 30.

[0036] The working principle and use process of this utility model:

[0037] Installation steps: clamp the filter mechanism 80 on the positioning protrusion 200 on the limiting pressure piece 60, and the positioning protrusion 200 is tightly clamped in the positioning circular groove 300, and then the knob 54 is turned forward, the bidirectional screw 51 is turned forward, and the upper and lower sliders 52 move closer to each other. Under the connection of the connecting rod 53, the upper and lower limiting pressure pieces 60 move closer to each other, and finally the upper filter mechanism 80 is embedded in the air outlet 20, and the lower filter mechanism 80 is embedded in the air inlet 30;

[0038] Removal steps: reverse the knob 54, and similarly, the upper and lower limit pressing plates 60 move away from each other, the filter mechanism 80 is separated from the air outlet 20 and the air inlet 30, and the filter mechanism 80 is directly removed.
