[0027] To further illustrate the embodiments, the utility model provides has the drawing. These drawings are part of the utility model disclosure, which is mainly used to illustrate the embodiments, and can be combined with the related description of the specification to explain the operating principle of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementations and the advantages of the utility model. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0028] The utility model is further illustrated in conjunction with the drawings and specific embodiments.

[0029] As Figures 1-8 Indicated, the embodiment provides an air formaldehyde removal purification device 1, including base 10 and filter core box 20, filter core box 20 is detachably installed on base 10, filter core box 20 is equipped with internal cavity, and the internal cavity is used to hold formaldehyde removal purification material, such as solid formaldehyde removal purification material.

[0030] Filter core box 20 includes box body 21 and top cover 22. Box body 21 and top cover 22 can be installed and matched, so that box body 21 and top cover 22 enclose to form an internal cavity for holding formaldehyde removal purification material. A plurality of air holes 222 are provided on the top cover 22 to improve the contact efficiency of the formaldehyde removal purification material in the filter core box 20 and the air, and improve the formaldehyde removal purification effect.

[0031] The inner wall of the box body 21 is provided with a clamping protrusion 211, and the top cover 22 is provided downwardly with a clamping lug 221, and the clamping lug 221 is provided with a clamping groove 223. The clamping protrusion 211 can be clamped and matched with the clamping groove 223, so that the top cover 22 can be detachably installed on the box body 21.

[0032] Referring to Figures 2-8 , the base 10 is provided with a box cavity 11, and the filter core box 20 is detachably installed in the box cavity 11 of the base 10. The outer periphery of the filter core box 20 is provided with a first rotation cooperation structure 23, and the inner wall of the box cavity 11 of the base 10 is provided with a second rotation cooperation structure 16. The first rotation cooperation structure 23 and the second rotation cooperation structure 16 can be rotationally matched, so that the filter core box 20 can be detachably installed on the base 10 by rotation. When the service life (product use cycle) of the solid formaldehyde removal purification material held by the filter core box 20 is reached, the consumer can replace the new filter core box 20 by rotating it himself, without having to throw away the entire product, saving materials and being more environmentally friendly.

[0033] The first rotation cooperation structure 23 includes an avoidance groove 231 and a limiting groove 232. The height direction of the filter core box 20 is defined as the longitudinal direction. The avoidance groove 231 extends upward from the bottom of the filter core box 20 in the longitudinal direction. The limiting groove 232 extends transversely from one side wall of the avoidance groove 231, and the limiting groove 232 is in communication with the avoidance groove 231.

[0034] The second rotary mating structure 16 includes a mating protrusion 161. The thickness F of the mating protrusion 161 is less than the longitudinal groove width D of the limiting groove 232, and the width E of the mating protrusion 161 is less than the transverse groove width C of the clearance groove 231. Thus, when the filter cartridge 20 is vertically inserted into the box cavity 11 of the base 10, the clearance groove 231 yields to the mating protrusion 161, allowing the mating protrusion 161 to reach the same height as the limiting groove 232. Subsequently, when the filter cartridge 20 is rotated relative to the base 10, the mating protrusion 161 engages with the limiting groove 232, forming a limit on the rotating filter cartridge 20, thereby enabling the filter cartridge 20 to be detachably installed on the base 10 by rotation. Of course, in other embodiments, the filter cartridge 20 can also be detachably installed on the base 10 by rotation in other ways, such as through a threaded connection.

[0035] Reference Figures 5-8 The limiting groove 232 is provided with a positioning protrusion 233, and the mating protrusion 161 is provided with a positioning slot 162. When the mating protrusion 161 is positioned in the limiting groove 232, the positioning protrusion 233 and the positioning slot 162 engage and cooperate, thereby firmly positioning the mating protrusion 161 in the limiting groove 232.

[0036] Furthermore, the inner wall of the box cavity 11 of the base 10 is provided with a slot 163, which is U-shaped, thereby forming a support block 164 in the slot 163. This structure makes the support block 164 have a greater elastic deformation capability. With the protrusion 161 located at the end of the support block 164, the positioning protrusion 233 can be more easily engaged with the positioning slot 162, making disassembly and assembly easier.

[0037] The inner wall of the cavity 11 of the base 10 is also provided with an auxiliary protrusion 12, and the outer circumferential surface of the filter cartridge 20 is provided with an auxiliary groove 24. The auxiliary protrusion 12 can be installed and cooperated with the auxiliary groove 24, thereby further strengthening the installation and positioning of the filter cartridge 20 relative to the base 10.

[0038] Reference Figure 1 , Figure 7 The upper edge of the base 10 is provided with multiple arc-shaped notches 13, which are evenly distributed along the upper edge of the base 10. In this embodiment, there are six arc-shaped notches 13. The arc-shaped notches 13 provide space for fingers, allowing the user to grip the filter cartridge 20 and thus facilitate the user's rotation of the filter cartridge 20. Furthermore, the multiple arc-shaped notches 13 give the upper edge of the base 10 a wavy design, making the product more aesthetically pleasing.

[0039] Reference Figures 5-8In the base 10, a battery box 14, a timing relay (not shown) and an indicator light 15 are also installed, the timing relay and the indicator light 15 are connected through a circuit control, the timing relay sets the same time as the product use cycle to count down; when the product reaches the purification life, the indicator light changes from green to red, so that the consumer can accurately judge the service life of the product. The battery box 14 supplies power for the timing relay and the indicator light 15 and the like. The battery box 14 is installed in the boss 17 at the bottom of the box cavity 11, the layout of the product is more reasonable, and the space utilization is higher.

[0040] The air de-aldehyde purification device 1 provided by the embodiment is provided with de-aldehyde purification solid material in the filter core box 20, the filter core box 20 is rotatably installed on the product base 10, when the de-aldehyde purification solid material reaches the service life (the product use cycle), the consumer can replace the new filter core box 20 by himself; meanwhile, the product is provided with a timing relay (sets the same time as the product use cycle to count down), the timing relay and the indicator light are connected through a circuit control, the indicator light changes from green to red, indicating that the product purification life reaches, so that the consumer can accurately judge the service life of the product. The air de-aldehyde purification device 1 product appearance is beautiful, can be installed on the indoor space wall or wall top and the like, so that the consumer has better choices.

[0041] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, those skilled in the art should understand that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all are within the protection scope of the utility model.
