DETAILED DESCRIPTION

[0024] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] 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 of 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.

[0026] It should be noted that all directional indications in the embodiments of the present invention (such as up-down-left-right-front-back...) are only used to explain the relative position relationship - movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0027] like Figure 1-Figure 6 As shown, an air purification device includes a middle frame 1 and a cover 2 snapped onto the middle frame 1, a first air hole 21 is opened in the middle of the cover 2, a first slot 22 is opened on the cover 2 at one side of the first air hole 21, a drawer plate 3 is snapped into the first slot 22, a second air hole 31 is opened on the drawer plate 3, a filter net (not shown in the figure) is attached to the second air hole 31, and the drawer plate 3 is used to draw out the filter net from the first slot 22 and move it to the outside of the cover 2.

[0028] By adopting the above technical solution, a filter is added to the air path, and the air entering or blown out is filtered through the filter, so as to reduce the tiny particles in the air; after the filter has been used for a period of time, the filter can be replaced by pulling out the draw plate 3, and then the draw plate 3 is pushed into the first notch 22, so that the filter can be replaced easily. Specifically, the filter adopts a melt-blown cloth sheet. The melt-blown cloth sheet is used to filter tiny debris in the air. The filter can be attached to the upper surface of the draw plate, or it can be attached to the lower surface of the draw plate. The filter can be bonded to the draw plate by double-sided tape, or the flange around the filter can be flipped to the other side of the draw plate to clamp the filter between the draw plate and the baffle on the cover.

[0029] Specifically, a mounting frame 11 protruding toward the face cover is provided in the middle of the middle frame 1, and the draw plate 3 is against the surface of the mounting frame 11. With the support of the mounting frame 11, the draw plate 3 is clamped between the mounting frame 11 and the face cover 2. A third air hole 12 is provided in the middle of the mounting frame 11 on the middle frame 1, and a fan 4 is installed on the side of the mounting frame 11 away from the face cover 2, and the fan 4 includes a fan blade and a motor for driving the fan blade to rotate; the fan blades of the fan 4 rotate to transport the air on one side of the middle frame 1 to the other side; a bottom cover 5 is installed on the side of the middle frame 1 away from the face cover 2, and a fourth air hole 51 is provided on the bottom cover 5. By starting the fan 4, air can form an airflow between the face cover 2 and the bottom cover 5, so that air in the environment is sucked into the space between the face cover 2 and the bottom cover 5 for filtration through the filter net, and purified by the negative ion generator 6. The fan 4 can rotate forward and reversely, so that the wind can be sucked in from the surface cover 2 and blown out from the bottom cover 5, or the wind can be sucked in from the bottom cover 5 and blown out from the surface cover 2. The bottom cover 5 is connected to the four corners of the fan 4 by bolts.

[0030] Specifically, the bottom cover 5 is a bowl-shaped structure with a downward depression in the middle, and the fourth air holes 51 are distributed on the peripheral side wall of the bottom cover 5. The fourth air holes 51 are arranged on the side to facilitate air intake, and are not arranged at the bottom to avoid blocking the fourth air holes 51 when the bottom cover 5 is placed on a table.

[0031] Specifically, a negative ion generator 6 is clamped on the bottom cover 5, and the negative ion generator 6 is used to generate negative air ions, and the release end of the negative ion generator 6 faces the gap between the fan 4 and the bottom cover 5. Thus, the released negative ions enter the gap, are blown out by the fan 4 and dispersed to the surrounding environment to purify the air, making the air fresh.

[0032] Specifically, a baffle 23 is provided in the inner wall of the face cover 2, and the baffle 23 is located on both sides of the draw plate 3 and guides the draw plate 3. A limit plate 24 is fixedly connected to the inner wall of the face cover 2, and the limit plate 24 is located at the end of the draw plate 3 away from the first notch 22 and limits the draw plate 3. The baffle 23 and the limit plate 24 are provided to guide and limit the draw plate 3, so that the position of the draw plate 3 remains stable. An upwardly protruding toggle block 32 is fixedly connected to the end of the draw plate 3. The toggle block 32 facilitates the draw plate 3 to be pulled out of the first notch 22. The outer edges of the middle frame 1, the face cover 2 and the bottom cover 5 are all set to be circular, and the outer edges of the three are flush.

[0033] The parts not involved in this technical solution can be implemented by using existing technologies.

[0034] The above shows and describes the basic principle, main features and characteristics of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model includes the attached claims and their equivalents.
