[0002] Desktop air purifiers, also known as air cleaners or air fresheners, are devices that can adsorb, decompose, or transform various air pollutants. With the improvement of people's living standards, air purifiers are widely used in daily life.
[0003] A Chinese patent with publication number CN205191767U discloses a desktop air purifier, which includes: a body configured to draw in airflow from an air inlet on its peripheral wall and blow it upward, and to purify the airflow entering the body; and a top cover assembly installed at the top of the body, which defines an annular air outlet duct inside, configured to receive the purified airflow from the body and to discharge the purified airflow circumferentially from the desktop air purifier.
[0004] However, the aforementioned desktop air purifiers have the following drawbacks: when used in humid environments such as the rainy season in the south, they are prone to mold growth, producing odors that are difficult to deal with. Utility Model Content
[0005] The purpose of this invention is to provide a desktop air purifier that has strong internal drying properties and a fragrance effect during use.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a desktop air purifier, comprising a purifier body and a base, wherein the purifier body is provided with an air inlet hood and an air outlet hood, the air inlet hood is provided with a filter screen, the air outlet hood is provided with a fan, the base is provided with a multi-functional box, the base is provided with an installation groove, the multi-functional box is positioned and cooperates with the installation groove, the multi-functional box includes a deodorizing chamber and a drying chamber, the deodorizing chamber is filled with perfume, and the drying chamber is filled with a desiccant.
[0007] By adopting the above technical solution, when the user uses the air purifier, air enters the main body of the purifier through the air inlet cover, is filtered by the filter, and then exits through the air outlet cover through the fan. A multi-functional box is installed in the base, and the user can place desiccant in the drying chamber to keep the air purifier dry and prevent bacteria from growing due to moisture, which would then produce odors. In addition, the user can add perfume to the deodorizing chamber. When the user uses the air purifier, the perfume evaporates and is dispersed into the surrounding environment by the fan, which has the effect of freshening the air and relieving stress.
[0008] A further feature of this invention is that the base is provided with a buckle, the buckle has a snap-fit recess, the air inlet shroud has a slot, one end of the slot has an insertion channel, and the other end of the slot has a snap-fit protrusion. When the base is fixedly installed on the air inlet shroud, the buckle and the snap-fit protrusion engage with each other.
[0009] By adopting the above technical solution, when installing the base, the buckle at the edge of the base is guided into the groove through the insertion channel. The buckle slides horizontally along the slot, so that the snap-fit protrusion engages with the snap-fit recess, thereby fixing the buckle. When disassembling the base, the user rotates the base to disengage the snap-fit recess from the snap-fit protrusion and slides it along the slot to the insertion channel. The user can then pull the base to separate it from the main body of the purifier, which facilitates the subsequent cleaning of the air inlet cover and replacement of the filter.
[0010] A further feature of this invention is that the deodorizing chamber has a connecting part, and the mounting groove is provided with a corresponding evaporation tube. When the multifunctional box is installed in the mounting groove, the connecting part and the evaporation tube are inserted and engaged.
[0011] By adopting the above technical solution, the multi-functional box is inserted into the installation slot during installation. At this time, the protruding connecting part at the top of the deodorizing chamber is positioned and inserted into the evaporation tube, so that the perfume evaporates into the evaporation tube and then diffuses outward through the evaporation tube.
[0012] A further feature of this invention is that the evaporation tube has multiple evaporation holes extending through it.
[0013] By adopting the above technical solution, the perfume evaporates into the internal space of the purifier body through the evaporation hole, which facilitates the evaporation of the perfume.
[0014] A further feature of this invention is that: a first adjusting plate is provided at the open end of the connecting part, a second adjusting plate is provided correspondingly for the evaporation tube, and an evaporation channel is provided between the evaporation tube and the connecting part.
[0015] By adopting the above technical solution, the size of the evaporation channel is controlled by the first and second adjusting plates, thereby adjusting the evaporation rate of the perfume.
[0016] A further feature of this invention is that the connecting portion can be rotated and adjusted relative to the evaporation tube to adjust the relative positions of the first adjusting plate and the second adjusting plate, thereby adjusting the opening size of the evaporation channel.
[0017] By adopting the above technical solution, users can control the position of the first and second adjusting plates by adjusting the insertion direction of the multi-functional box, thereby controlling the shape of the evaporation channel. When the perfume demand is high, the first and second adjusting plates completely overlap, and the opening is large. When the perfume demand is low, the first and second adjusting plates partially overlap, and the opening is small. When perfume is not needed, the first and second adjusting plates are relatively closed, and the opening is closed, thus reasonably setting the perfume evaporation speed and avoiding perfume waste.
[0018] A further feature of this invention is that the connecting part has a rubber layer on the side wall near the evaporation tube, and the rubber layer is interference-fitted with the inner wall of the evaporation tube.
[0019] By adopting the above technical solution, the friction between the connecting part and the evaporation tube is increased, thereby improving the installation stability between the multi-functional box and the mounting groove and making it less likely to fall off.
[0020] A further feature of this invention is that a counterweight is provided at the bottom of the drying chamber, and the desiccant is disposed on the counterweight.
[0021] By adopting the above technical solution, the center of gravity of the air purifier is lowered under the action of the counterweight, thereby improving the air purifier's anti-tipping ability.
[0022] A further feature of this invention is that a through hole is provided through the upper wall of the mounting groove, and the through hole connects the drying chamber and the internal space of the purifier body.
[0023] By adopting the above technical solution, the drying chamber is connected to the internal space of the purifier body, which improves the drying efficiency of the drying chamber and makes it easier to keep the purifier body dry.
[0024] A further feature of this invention is that the base is provided with a first limiting rib and a second limiting rib in a circumferential direction, the outer side of the filter screen abuts against the inner side of the first limiting rib, and the inner side of the filter screen abuts against the outer side of the second limiting rib.
[0025] By adopting the above technical solution, installation is convenient. When replacing the filter, the filter is pulled out axially and the new filter is inserted between the first and second limiting ribs, which improves the convenience of filter replacement.
[0026] In summary, this utility model has the following beneficial effects: 1. It adopts a multi-functional box with a drying chamber, which keeps the inside of the purifier dry, prevents bacterial growth, and reduces odors.
[0027] 2. It adopts a multi-functional box with a deodorizing chamber, which can freshen the air and remove odors.

[0039] The present invention will be further described below with reference to the accompanying drawings.
[0040] A desktop air purifier, such as Figure 1 , 2As shown, the air purifier includes a main body 1 and a base 2. The main body 1 is equipped with an air inlet hood 11 and an air outlet hood 12. A filter 13 is arranged circumferentially inside the air inlet hood 11, and a fan 14 is installed inside the air outlet hood 12. When the air purifier is working, air enters the main body 1 through the air inlet hood 11, is filtered and purified by the filter 13, and is discharged into the surrounding environment under the action of the fan 14. The base 2 has an installation slot 22, in which a multi-functional box 21 can be detachably installed. The multi-functional box 21 includes a deodorizing chamber 23 and a drying chamber 24. The deodorizing chamber 23 contains a perfume 231, and the drying chamber 24 contains a desiccant 241. The desiccant 241 dries the air entering the main body 1, preventing bacterial growth caused by internal dampness, which would lead to odors and affect the filtration effect of the filter 13. In addition, the perfume 231 evaporates and is carried out by the fan 14, freshening the surrounding air and relieving user stress.
[0041] like Figure 2 , 5 As shown in Figures 6 and 7, in this embodiment, several buckles 25 are arranged circumferentially around the edge of the base 2. Each buckle 25 includes a snap-fit recess 251. Several slots 111 are correspondingly opened circumferentially on the inner side of the air inlet shroud 11. When the user installs the base 2, the buckles 25 are snapped into the slots 111. One end of the slot 111 is provided with an insertion channel 112. The insertion channel 112 and the slot 111 together form an L-shaped locking groove structure for locking with the buckles 25. The buckles 25 are guided into the slots 111 by the insertion channel 112. The user can rotate the base 2. The base 2 is positioned so that the buckle 25 slides circumferentially relative to the slot 111. When the buckle 25 slides to the other end of the slot 111, the snap-fit protrusion 113 engages with the snap-fit recess 251, thus fixing the base 2 in place and improving the stability of the base 2 installation. When disassembling the base 2, the user rotates the base 2 so that the snap-fit recess 251 disengages from the snap-fit protrusion 113 and slides along the slot 111 to the insertion channel 112. The user then pulls the base 2 to separate it from the purifier body 1, facilitating the subsequent cleaning of the air inlet shroud 11 and the replacement of the filter 13.
[0042] like Figure 2 , 7 As shown, in this embodiment, the upper end of the drying chamber 24 is provided with an opening, and the bottom of the drying chamber 24 is provided with a counterweight 242. The desiccant 241 is placed on the counterweight 242. Under the action of the counterweight 242, the center of gravity of the air purifier is lowered, which improves the anti-tipping ability of the air purifier. In addition, the upper wall of the mounting groove 22 is provided with a through hole 224, which connects the drying chamber 24 and the internal space of the purifier body 1, improving the drying efficiency of the drying chamber 24 and making it easier to keep the purifier body 1 dry.
[0043] like Figure 2 , 4As shown in Figure 8, in this embodiment, the deodorizing chamber 23 has a connecting part 232, and the mounting groove 22 is correspondingly provided with an evaporation tube 221. The end of the evaporation tube 221 has several evaporation holes 222. When the user installs the multi-functional box 21, the connecting part 232 and the evaporation tube 221 are inserted into each other. When the user uses the product, the perfume 231 evaporates into the evaporation tube 221, and then diffuses outward through the evaporation holes 222 to remove odors. Furthermore, the connecting part 232 has an elastic band on its side wall near the evaporation tube 221. The adhesive layer 234 and the rubber layer 234 are interference-fitted with the inner wall of the evaporation tube 221, which increases the friction between the connecting part 232 and the evaporation tube 221, thereby improving the installation stability between the multi-functional box 21 and the mounting groove 22 and making it less likely to fall off. In other embodiments, protrusions can be provided on the side wall of the multi-functional box 21 and corresponding concave points can be provided on the mounting groove 22, so that the protrusions are placed into the concave points when the multi-functional box 21 is installed, which can also achieve the effect of improving the installation stability of the multi-functional box 21.
[0044] like Figure 3 , 8 As shown in Figure 9, in this embodiment, the opening end of the connecting part 232 is provided with a first adjusting plate 233, and the evaporation tube 221 is correspondingly provided with a second adjusting plate 223. An evaporation channel 26 is formed between the evaporation tube 221 and the connecting part 232. The user can adjust the size of the evaporation channel 26 through the first adjusting plate 233 and the second adjusting plate 223, thereby adjusting the evaporation speed of the perfume 231. When the first adjusting plate 233 and the second adjusting plate 223 are completely overlapped, a semi-circular evaporation channel 26 is formed between the evaporation tube 221 and the connecting part 232, so that the perfume 231 evaporates faster, which is suitable for scenarios where the demand for perfume 231 is large. The user can change the installation position of the multi-functional box 21 so that the first adjusting plate 233 and the second adjusting plate 223 partially overlap, and the evaporation tube 221 and the connecting part 232 form a quarter-circular second channel. At this time, the perfume 231 evaporates at a slower speed, which is suitable for scenarios where the demand for perfume 231 is small. Similarly, by adjusting the installation position of the multi-functional box 21, the first adjusting plate 233 and the second adjusting plate 223 are relatively closed, and the evaporation channel 26 is closed. At this time, the perfume 231 does not evaporate, which is suitable for scenarios where perfume 231 is not needed. The user can control the evaporation speed of perfume 231 according to the actual usage scenario to avoid wasting perfume 231.
[0045] like Figure 7As shown, in this embodiment, the base 2 is provided with a first limiting rib 27 and a second limiting rib 28 in a circumferential manner. The outer side of the filter screen 13 abuts against the inner side of the first limiting rib 27, and the inner side of the filter screen 13 abuts against the outer side of the second limiting rib 28. When the filter screen 13 is installed, it is inserted between the first limiting rib 27 and the second limiting rib 28, which facilitates the positioning and installation of the filter screen 13. When the filter screen 13 is replaced, the filter screen 13 is pulled out axially, and the new filter screen 13 is inserted between the first limiting rib 27 and the second limiting rib 28, which improves the convenience of replacing the filter screen 13 and makes it easier for users to replace the filter screen 13.
[0046] The basic working principle of this utility model is as follows: Air enters the air purifier body 1 through the air inlet cover 11, is purified by the filter 13, and is discharged through the air outlet cover 12. The base 2 is provided with a multi-functional box 21 and an installation slot 22 for installing the multi-functional box 21. The multi-functional box 21 includes a deodorizing chamber 23 and a drying chamber 24. By placing a desiccant 241 in the drying chamber 24, the air purifier is kept dry. By adding perfume 231 in the deodorizing chamber 23, the perfume 231 evaporates and is carried out by the fan 14, thus freshening the air and improving the user experience.
[0047] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
