Description

Technical Field

[0001] This utility model relates to the technical field of air purification, and in particular to a negative ion air purification device. Background Technology

[0002] To ensure the accuracy of experimental results, a high level of air cleanliness is required in the laboratory. Generally, an air purifier is installed in the laboratory to purify the air, filter out dust particles, and prevent experimental personnel from inhaling toxic and harmful gases generated during the experiment, which could affect their health.

[0003] Existing air purifiers consist of a housing and a filter assembly inside the housing. The housing has an air inlet and an air outlet. The filter assembly mainly includes a negative ion generator and an activated carbon plate. The negative ion generator can agglomerate and settle particulate matter and decompose harmful gases, while the activated carbon plate can adsorb the settled particulate matter and odors in the gas. Since the air outlet is generally located at the bottom of the housing, the air outlet angle is fixed. However, since there are multiple experimental tables in the laboratory for different experiments, the fixed air outlet angle means that some experimental tables cannot be replenished with purified air in time. This can easily cause physical discomfort to the experimenters at these tables and result in low accuracy of experimental results. To address this, an adjustable air outlet curtain is installed at the air purifier's air outlet. However, this air outlet curtain needs to be manually rotated and adjusted. Before the experiment, the experimenters need to climb a ladder to the top of the laboratory to adjust it. This requires multiple climbs and adjustments to achieve the optimal angle when conducting experiments on different experimental tables, causing serious inconvenience to the experimenters.

Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] See Figure 1 and Figure 2 This embodiment relates to a negative ion air purifier, including a shell 1 and a cover plate 2 that are detachably connected to each other, and a negative ion purification mechanism disposed inside the shell 1; the shell 1 forms a receiving chamber for accommodating the negative ion purification mechanism, the bottom of the shell 1 is provided with an air outlet 3, and the cover plate 2 is provided with an air inlet 4; gas can enter the shell 1 from the air inlet 4 on the cover plate 2, flow in the receiving chamber and be purified by the negative ion purification mechanism, and then be blown out from the air outlet 3 on the shell 1.

[0023] An electric air guide curtain 5 is provided at the air outlet 3 of the outer casing 1. When the electric air guide curtain 5 is open, the purified gas can be blown out from the air outlet 3 of the outer casing 1, and the air outlet angle can be adjusted by rotation.

The controller controls the rotation of the electric air guide curtain 5 to adjust the air outlet angle.

[0024] Specifically, the outer casing 1 is a rectangular box structure, including a top plate, a bottom plate, a back plate, and two side plates that are spliced ​​together. The outer casing 1 is provided with a mounting opening opposite to the back plate. The outer casing 1 is provided with an air outlet 3 on the bottom plate. The cover plate 2 is detachably installed on the mounting opening of the outer casing 1 to form a gas flow path inside the outer casing 1 from the air inlet on the cover plate 2 to the air outlet 3 on the outer casing 1. The negative ion purification mechanism includes a crossflow fan 6 and a negative ion purifier 7 installed on the gas flow path. The crossflow fan 6 has an air inlet side for drawing in gas and an air outlet side for discharging gas. On the side, the air inlet side of the crossflow fan 6 is opposite to the air inlet on the cover plate 2, and the air outlet side of the crossflow fan 6 is opposite to the air outlet 3 on the outer shell 1; in this embodiment, the negative ion purifier 7 is a conventional negative ion purification device in the prior art. The negative ion purifier 7 is located between the air outlet side of the crossflow fan 6 and the air outlet 3 on the outer shell 1; during purification, indoor air is drawn into the interior of the outer shell 1 through the air inlet 4, flows from the air inlet side of the crossflow fan 6 to the air outlet side in the accommodating chamber, and after being purified by the negative ion purifier 7, it is blown out at the air outlet 3 through the air guide curtain according to the air outlet angle.

[0025] The cover plate 2 includes a straight section and a curved section integrally formed at the bottom of the straight section. During installation, the straight section of the cover plate 2 is parallel to the back plate of the outer shell 1, and an air inlet 4 is provided on the straight section. A radar component is provided on the inner side of the curved section of the cover plate 2. The radar component is used to detect the position of people in the room and send the personnel position signal to the controller inside the outer shell 1. The controller controls the electric air guide curtain 5 to rotate according to the personnel position signal to adjust the air outlet angle. When the personnel position changes, the radar component obtains the new personnel position signal and sends it to the controller. The controller controls the electric air guide curtain 5 to rotate again so that the air outlet angle of the electric air guide curtain 5 can change with the personnel position without manual adjustment.

[0026] The radar component includes a radar body 8 and a driving component for driving the radar body 8. The radar body 8 is movably disposed inside the curved section of the cover plate 2. A guide portion is provided inside the curved section of the cover plate 2. The guide portion is used to install the radar body 8 on the curved section of the cover plate 2 and guide the radar body 8 to slide along a preset trajectory inside the curved section of the cover plate 2, so as to change the installation position of the radar body 8 and correspondingly change the detection angle of the radar body 8 to avoid the generation of detection blind spots.

[0027] The curved section of the cover plate 2 has an inner mounting surface that can fit together with the detection end face of the radar body 8 when the radar body 8 is installed. The radar body 8 can slide relative to the cover plate 2 on the mounting surface according to a preset trajectory to change its installation position.

[0028] The guide portion on the curved section of the cover plate 2 is a guide rail 9. The guide rail 9 is used to form a preset trajectory for the radar body 8 to slide on the inner side of the curved section of the cover plate 2. One end of the guide rail 9 is closed, and the other end of the guide rail 9 forms an opening. The radar body 8 has a first mating part 81 and a second mating part 82. The first mating part 81 is located at the top of the radar body 8 and is connected to the drive component. The second mating part 82 is located on opposite sides of the radar body 8 and is slidably connected to the guide rail 9 through the open end of the guide rail 9 so that the radar body 8 can slide along the guide rail 9.

[0029] A driving force is provided to the radar body 8 through a driving component, so that the radar body 8 can slide along the guide rail 9; when the radar body 8 slides from the first position to the second position along the mounting surface on the curved section of the cover plate 2, the mounting angle is changed towards the top of the cover plate 2; when the radar body 8 slides from the second position to the first position along the mounting surface on the curved section of the cover plate 2, the mounting angle is changed towards the bottom of the cover plate 2; it should be noted that in this embodiment, the first position is the open end of the guide rail 9, the second position is the closed end of the guide rail 9, and the second position is closer to the top of the cover plate 2 than the first position.

[0030] In this embodiment, the guide rail 9 is an arc-shaped guide rail, and the curvature of the guide rail 9 corresponds to the curvature of the mounting surface on the curved section of the cover plate 2. In this embodiment, the radar body 8 is a millimeter-wave radar in the prior art. The first mating part 81 of the radar body 8 is connected to the driving part through a swinging member. One end of the swinging member is a fixed end and is connected to the output end of the driving member. The other end of the swinging member is a free end and is hinged to the first mating part 81 of the radar body 8. The driving member generates torque, which drives the free end of the swinging member to swing around the fixed end through the output end of the driving member. Correspondingly, the radar body 8 slides along the guide rail 9 on the mounting surface of the curved section of the cover plate 2 to change the mounting angle of the radar body 8.

[0031] The swinging component is an electric telescopic rod 10, which includes an outer rod 101 and an inner rod 102 sleeved inside the outer rod 101. The fixed end of the outer rod 101 is fixedly connected to the output end of the drive component. The free end of the inner rod 102 is provided with a hinge joint 11, and the inner rod 102 is hinged to the first mating part 81 of the radar body 8 through the hinge joint 11. When the drive component generates torque, the free end of the outer rod 101 swings around the fixed end of the outer rod 101, which in turn drives the free end of the inner rod 102 to swing, so that the radar body 8 slides along the guide rail 9 on the mounting surface of the curved section of the cover plate 2. During the sliding process of the radar body 8, the free end of the inner rod 102 rotates relative to the radar body 8 around the hinge point through the hinge joint 11, and extends and retracts axially relative to the outer rod 101, so that the radar body 8 is fed in an arc in space to adapt to the curvature of the mounting surface of the curved section of the cover plate 2.

[0032] The driving component is a servo motor 12 fixedly mounted on the mounting surface of the curved section of the cover plate 2 via a support frame. The output shaft of the servo motor 12 is fixedly connected to the fixed end of the outer rod 101. When the output shaft of the servo motor 12 rotates, it drives the free end of the outer rod 101 to swing around the output shaft of the servo motor 12, which in turn drives the free end of the inner rod 102 to swing, thereby driving the radar body 8 to slide along the guide rail 9 on the mounting surface of the curved section of the cover plate 2 to change the mounting angle. After the installation angle change is completed, the servo motor 12 stops, and the inner rod 102 of the electric telescopic rod 10 stops axial extension and retraction and maintains support for the radar body 8, so that the radar body 8 maintains the changed installation angle.

[0033] In this embodiment, the radar body 8 obtains personnel position data and sends the personnel position data to the controller. The controller controls the servo motor 12 to rotate and the electric telescopic rod 10 to extend and retract according to the personnel position data, which drives the radar body 8 to slide along the guide rail 9 to change the installation angle, so that the detection angle of the radar body 8 changes accordingly with the movement of the personnel, thereby continuously acquiring personnel position data. The controller can also continuously receive personnel position data so as to dynamically adjust the air outlet angle of the air guide curtain in real time.

[0034] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
