Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air purifiers, in particular to an air purifier with a linkage dismounting filter screen structure. BACKGROUND

[0002] With the increasing emphasis on indoor air quality, air purifiers have become an indispensable electrical appliance in homes, offices and other places. Its core working principle is to filter particulate matter, odors and other impurities in the air through internal filter screens, thereby achieving air purification. However, in the long-term use process, the existing air purifiers have obvious defects in filter screen maintenance and use convenience, mainly in the following two points: On the one hand, the exposure of the air inlet when the filter screen is taken out causes the internal pollution of the equipment. The filter screen of the current air purifier is mostly installed in the internal chamber of the equipment, and the equipment shell (such as the top cover plate, side panel, etc.) needs to be disassembled when replacing the filter screen. This process will completely expose the air inlet inside the equipment to the air. Unfiltered air from the outside will directly enter the internal chamber through the exposed air inlet, which not only may pollute the internal air duct, fan motor assembly and other core components, affecting the service life of the equipment, but also may cause the subsequent internal accumulation of impurities to be discharged with the airflow, thereby causing secondary pollution of indoor air. In addition, a large amount of dust, bacteria and other impurities adsorbed on the old filter screen may also fall off and spread due to the airflow disturbance caused by the exposure of the air inlet during the removal process, further aggravating the deterioration of indoor air quality.

[0003] On the other hand, the single filter screen design forces the equipment to stop when replacing, affecting the continuity of purification. Most of the existing air purifiers are equipped with only a single air inlet and a single filter screen, so that once the filter screen needs to be replaced, the equipment must be stopped, otherwise unfiltered air will directly enter and exit through the air inlet without filter screen shielding. This results in that the air purifier cannot work normally during the filter screen replacement period, and cannot achieve online replacement of the filter screen without stopping, affecting the continuity of purification.

[0023] The following detailed description provides various embodiments or examples for implementing the present invention. These are, of course, merely examples and are not intended to be limiting. Furthermore, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. Such repetition is for simplicity and clarity in describing the present invention and does not imply a specific relationship between the various embodiments and / or configurations discussed.

[0024] like Figures 1-6 The air purifier shown in the figure has a linkage detachable filter structure, including a cylindrical base shell 1, an inner cylinder 2 arranged in the base shell 1, and a fan motor assembly 3 arranged at the upper end of the inner cylinder 2. The upper end of the base shell 1 is provided with an air outlet assembly 4, two external air inlets 5 are symmetrically arranged on the outer wall of the base shell 1, two internal air inlets 6 corresponding to the external air inlets 5 are provided on the inner cylinder 2, and a filter cover shell 7 covered with through holes is hingedly installed on each of the external air inlets 5. A filter screen 8 and a locking device are provided on the inner side of the filter cover shell 7. The filter screen 8 and the filter cover shell 7 are detachable. The locking device can lock the filter cover shell 7 in a state of closing the outer air inlet 5. An inner cover assembly is slidably installed on the outer wall of the inner cylinder 2 along its circumferential direction. An unlocking assembly is provided on the inner cover assembly. The inner cover assembly can slide to close or open the inner air inlet 6, and when the inner cover assembly closes the inner air inlet 6, the unlocking assembly unlocks the locking device.

[0025] The fan motor assembly 3 is powered on and started, forming a negative pressure in the inner cylinder 2. The outside air enters from the external air inlet 5, and after initially blocking large particles of impurities through the through holes of the filter cover shell 7, it is filtered through the filter screen 8; the purified air enters the inner cylinder 2, flows upward under the action of the fan, and is finally discharged from the air outlet assembly 4; at this time, the inner cover assembly is in the open state, the inner air inlet 6 is completely exposed, the locking device remains engaged, and the filter cover shell 7 stably covers the external air inlet 5.

[0026] When the filter screen needs to be replaced, the inner cover assembly is pushed to slide along the inner cylinder 2 slide rail until it completely covers the inner air inlet 6; the unlocking assembly moves synchronously during the process, contacts and pushes open the locking device, and releases the locking of the filter cover shell 7; the filter cover shell 7 is turned over, and the old filter screen 8 is taken out from the inside of the filter cover shell 7. After the new filter screen is installed, the cover shell is closed, and the locking device is automatically engaged; the inner cover assembly is reversely slid to open the inner air inlet 6, and the equipment restores the purification function.

[0027] Therefore, the structure of the present application effectively solves the problem of air inlet exposure through the linkage structure of "outer air inlet + filter cover shell + inner air inlet + inner cover assembly". When the filter screen 8 needs to be removed, the inner cover assembly needs to be slid to close the inner air inlet 6, at which time the unlocking assembly on the inner cover assembly will unlock the locking device of the filter cover shell 7, allowing the filter cover shell 7 to be opened to replace the filter screen. During this process, the inner air inlet 6 has been closed in advance, and the internal air duct of the equipment is completely isolated from the outside world, so that the uncleaned air outside cannot enter the internal air duct. At the same time, the filter screen 8 is detachably connected with the filter cover shell 7, and the filter screen 8 remains relatively fixed with the cover shell during replacement, reducing the contact area between the filter screen and the air and reducing the risk of old filter screen impurity falling and spreading, thereby fundamentally avoiding the pollution of the internal air duct and the secondary pollution of indoor air.

[0028] In addition, two outer air inlets 5 are symmetrically arranged on the front and back of the base shell 1, and each outer air inlet 5 is correspondingly provided with a filter cover shell 7 and a filter screen 8, forming a double-filter-screen independent working structure. When one of the filter screens needs to be replaced, only the inner cover assembly and the filter cover shell 7 on one side need to be operated: the inner cover assembly on the corresponding side is slid to close the inner air inlet on that side, the filter cover shell is unlocked and opened to replace the filter screen, and the filter screen on the other side remains in normal working condition. The air purifier can continuously intake and filter air through the outer air inlet and the inner air inlet on the other side. This design completely breaks through the limitation of traditional single-filter-screen replacement, realizes non-stop replacement of the filter screen, effectively avoids the purification "window period", ensures that the indoor air is always in a state of continuous purification, and is especially suitable for scenes with high requirements for air quality.

[0029] Further, a hinge shaft 21 is arranged at the middle position of the lower end of the filter cover shell 7, a hinge seat 22 is arranged at the middle position of the lower end of the outer air inlet 5, the hinge shaft 21 is rotatably arranged on the hinge seat 22, and a handle 31 is arranged on the outer side of the upper end of the filter cover shell 7.

[0030] When the filter screen is replaced, the handle 31 is directly pulled outward after the locking device is unlocked, and the filter cover shell 7 rotates around the hinge seat 22 with the hinge shaft 21 as the center until it is completely opened.

[0031] Further, there are arc-shaped sliding grooves 41 symmetrically arranged on the inner side of the filter cover shell 7, and the filter screen 8 is slidably arranged in the two arc-shaped sliding grooves 41.

[0032] When installing the filter screen 8, align the upper and lower edges of the filter screen with the entrance of the arc-shaped sliding groove 41, push the filter screen along the sliding groove until the filter screen completely fits the inner side of the cover shell; when disassembling, push the filter screen to slide reversely along the sliding groove, and then it can be taken out; the sliding groove limits the movement of the filter screen in the vertical direction, and ensures that the filter screen always covers the through hole of the cover shell, thereby avoiding displacement to cause filtering failure.

[0033] Referring to FIG. 5, a plurality of pressing strips 51 are spaced apart from each other in the vertical direction in the outer air inlet 5, and when the filter cover shell 7 covers the outer air inlet 5, the pressing strips 51 press the filter screen 8 tightly on the filter cover shell 7, thereby improving the stability of the filter screen 8 after installation. Figure 2 Figure 3 Referring to FIG. 5, a plurality of pressing strips 51 are spaced apart from each other in the vertical direction in the outer air inlet 5, and when the filter cover shell 7 covers the outer air inlet 5, the pressing strips 51 press the filter screen 8 tightly on the filter cover shell 7, thereby improving the stability of the filter screen 8 after installation.

[0034] Referring to FIG. 5, a plurality of pressing strips 51 are spaced apart from each other in the vertical direction in the outer air inlet 5, and when the filter cover shell 7 covers the outer air inlet 5, the pressing strips 51 press the filter screen 8 tightly on the filter cover shell 7, thereby improving the stability of the filter screen 8 after installation. Figure 5 Figure 6 Referring to FIG. 5, a plurality of pressing strips 51 are spaced apart from each other in the vertical direction in the outer air inlet 5, and when the filter cover shell 7 covers the outer air inlet 5, the pressing strips 51 press the filter screen 8 tightly on the filter cover shell 7, thereby improving the stability of the filter screen 8 after installation.

[0035] Further, the elastic locking piece 72 comprises a movable groove 61 arranged on the lower side of the fixed seat 71, a locking block 62 movably arranged in the movable groove 61, and a spring 63 arranged between the locking block 62 and the movable groove 61 to keep the locking block 62 in a downward state. When the locking block 62 extends out of the movable groove 61 downward, a locking gap 64 is formed between the locking block 62 and the inner wall of the filter cover shell 7, and the locking gap 64 can accommodate the clamping strip 73. A first guide inclined surface 65 is arranged at the lower end of the locking block 62.

[0036] When the filter cover shell 7 is closed, the cover shell rotates around the hinge shaft 21, the clamping strip 73 contacts the first guide inclined surface 65 of the locking block 62, the clamping strip applies an inclined force to the inclined surface, which is decomposed into an upward component force, pushes the locking block to compress the spring 63 and move upward into the movable groove 61. When the cover shell is completely closed, the clamping strip moves to the position of the locking gap 64, the spring returns to the original state, pushes the locking block to extend downward, and the clamping strip is clamped into the gap to achieve locking. When unlocking, the external force pushes the locking block upward to compress the spring, the locking block enters the movable groove, the clamping strip is separated from the gap, and the locking is released.

[0037] The unlocking assembly comprises a top plate 81 arranged on the inner cover assembly. When the top plate 81 slides with the inner cover assembly to close the inner air inlet 6, the top plate 81 pushes the locking block 62 into the movable groove 61. One end of the top plate 81 for contacting and pushing the locking block 62 is provided with a second guide inclined surface 82.

[0038] ​​When the sliding inner cover assembly closes the inner air inlet 6, the top plate 81 moves synchronously with the inner cover assembly, and the second guide inclined surface 82 gradually approaches the locking block 62. After contacting the locking block 62, the inner cover assembly continues to slide, and the top plate 81 exerts an upward thrust on the locking block 62, pushing the locking block 62 to move upward to compress the spring 63 and enter the active slot 61, thereby releasing the locking of the clamping strip 73. When the inner cover assembly slides reversely, the top plate 81 is separated from the locking block 62, and the spring 63 pushes the locking block 62 to reset, so that the locking can be re-established.

[0039] In the present application, the inner cover assembly comprises two arc-shaped sliding plates 91 arranged at intervals left and right. When the two arc-shaped sliding plates 91 are combined, the inner air inlet 6 is closed, and the two arc-shaped sliding plates 91 are provided with unlocking assemblies. The elastic locking members 72 are arranged in two groups at intervals left and right, and correspond to the two groups of unlocking assemblies.

[0040] When the air purifier is in normal operation and the filter screen does not need to be replaced, the two arc-shaped sliding plates 91 are in a left and right separated state and are located on both sides of the outer wall of the inner cylinder 2. At this time, the inner air inlet 6 is completely exposed and does not hinder the air entering the inner cylinder 2 from the inner air inlet 6. At the same time, since the two arc-shaped sliding plates are not combined, the unlocking assemblies (top plates 81) thereon are not in effective contact with the elastic locking members 72 on the inner side of the filter cover shell 7, and the elastic locking members 72 remain in the state of clamping the clamping strip 73 in the outer air inlet 5. The filter cover shell 7 is stably covered on the outer air inlet 5, ensuring that the air inlet filtering process proceeds normally.

[0041] When the filter screen 8 needs to be replaced, the user needs to push the two arc-shaped sliding plates 91 at the same time, so that the two sliding plates slide to the middle along the annular sliding rail on the outer wall of the inner cylinder 2. With the movement of the sliding plates, the top plates 81 on the two sliding plates also move synchronously towards the elastic locking members 72. Since the elastic locking members 72 are arranged in two groups at intervals left and right, and correspond to the two groups of unlocking assemblies (top plates 81), only when the two arc-shaped sliding plates 91 are completely combined, the top plates 81 on both sides can be in precise contact with the corresponding elastic locking members 72. After contacting, the top plate 81 continues to exert a thrust on the combined arc-shaped sliding plate, and the locking block 62 in the elastic locking member 72 is pushed into the active slot 61, so that the locking block 62 is separated from the clamping strip 73, thereby releasing the locking of the filter cover shell 7. If only one arc-shaped sliding plate 91 is pushed, the top plate 81 on the sliding plate can only contact one side of the elastic locking member 72, and cannot trigger the unlocking of the two groups of elastic locking members at the same time. The filter cover shell 7 is still in the locked state and cannot be opened.

[0042] Therefore, through the design that the left and right arc-shaped slides need to be combined to be unlocked, a "double trigger" unlocking mechanism is formed, which effectively avoids the unlocking caused by accidental touch of a single arc-shaped slide. For example, if one of the arc-shaped slides is accidentally touched in daily use, the other slide cannot be moved to achieve combination, the unlocking assembly cannot trigger the two sets of elastic locking members to unlock, and the filter cover shell remains locked, preventing the filter cover shell from being accidentally opened to expose the filter screen or allow foreign matter to enter the device, thereby significantly improving the safety and stability of the device in use.

[0043] A push block 10 is arranged on the arc-shaped slide 91, and a guide sliding groove 11 corresponding to the push block 10 is arranged on the outer wall of the base shell 1.

[0044] The push block 10 is arranged on the arc-shaped slide 91, which provides a direct and precise force application position for the user to slide the arc-shaped slide. The user only needs to pinch or push the push block 10 with the fingers, which can easily drive the arc-shaped slide to slide along the sliding rail on the outer wall of the inner cylinder 2, without the need for tools or force pressing, thereby significantly improving the user operation experience.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
