DETAILED DESCRIPTION
[0028] The following is a specific embodiment of the utility model and further describes the technical method of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.
[0029] As shown in Figures 1-4 The utility model provides an air purifier's air inlet and outlet structure, comprising:
[0030] The air purifier body 100 is internally provided with an air inlet cavity and an air outlet cavity which are isolated from each other, and the air inlet cavity and the air outlet cavity are communicated through the communication port 121;
[0031] The outer peripheral wall of the air purifier body 100 is provided with the air inlet 131 and the air outlet 141 which are arranged in a circumferential direction, wherein,
[0032] The air inlet 131 is located at the upper layer of the air purifier body 100 and is communicated with the air inlet cavity, allowing air to enter the purifier from various directions, increasing the area and efficiency of air suction,
[0033] The air outlet 141 is located at the lower layer of the air purifier body 100 and communicates with the air outlet cavity, which helps to uniformly release the purified air into the environment.
[0034] It is worth mentioning that the air inlet 131 and the air outlet 141 are both arranged circumferentially along the outer peripheral wall of the air purifier body 100, which can realize 360° circumferential air inlet and air outlet. This design ensures that the air purifier can quickly process air in a larger range, greatly improving the efficiency of air intake and exhaust, thereby enabling the air purifier body 100 to fully exert its purification efficiency and improve the purification efficiency.
[0035] Among them, the filter screen 110 for filtering air is arranged in the air inlet cavity and covers the communication port 121 between the air inlet cavity and the air outlet cavity. Since the air inlet cavity and the air outlet cavity are only connected through the communication port 121, the air flowing from the air inlet cavity to the air outlet cavity must pass through the filter screen 110 for filtering, ensuring good air purification effect.
[0036] In addition, the filter screen 110 in the present embodiment is arranged in a closed cylindrical structure. After the air enters the air inlet cavity from the air inlet screen, it enters the inner cavity of the filter screen 110 from each side of the filter screen 110, realizing the first filtering. Subsequently, the air filtered once enters the air outlet cavity from the bottom of the filter screen 110 through the communication port 121. In this process, the air filtered once again passes through the filter screen 110 and realizes the second filtering.
[0037] The double filtering mechanism of the filter screen 110 ensures that even tiny particles can be effectively captured, thereby significantly improving the air purification effect.
[0038] Overall, through the innovative design of the air inlet and outlet structure, not only the problem of low purification efficiency in the prior art is solved, but also the working performance of the air purifier is significantly enhanced, providing a more healthy and comfortable indoor environment for users.
[0039] The specific structure design of the air purifier body 100 is described as follows:
[0040] Preferably, the air purifier body 100 comprises:
[0041] The air outlet base 120 provides a mounting platform;
[0042] The air outlet screen 140 is arranged in a cylindrical structure penetrating from top to bottom and surrounds the outer peripheral surface of the air outlet base 120. The inner cavity of the air outlet screen 140 connected with the air outlet base 120 forms the air outlet cavity, and the surface of the air outlet screen 140 is uniformly distributed with mesh holes and forms the air outlet 141;
[0043] The air inlet net is arranged in a through-up-and-down cylindrical structure and around the edge of the top of the air outlet base 120, wherein the inner cavity formed by the air inlet net itself is an air inlet cavity, and the surface of the air inlet net is uniformly provided with mesh holes and forms an air inlet 131.
[0044] Through the design of the structures of the air inlet net and the air outlet net 140, the air inlet 131 and the air outlet 141 can realize the function of circulating air in a circumferential direction of 360°, thereby finally improving the purification efficiency.
[0045] That is, the whole air purifier body 100 is composed of the filter screen 110, the air inlet net, the air outlet base 120 and the air outlet net 140, air enters the air inlet cavity from the air inlet net, enters the inner cavity of the filter screen 110 from the circumferential surface of the filter screen 110, enters the air outlet cavity from the bottom surface of the filter screen 110 through the communication port 121, and is finally released outward from the air outlet net 140.
[0046] In addition, it is worth mentioning that most of the existing products adopt a rear-mounted or side-open filter screen 110 storage design, and the user needs to open the cover, remove the buckle or screw the fixing part to take out the filter screen 110, which is not only troublesome to disassemble, but also requires the user to closely contact the surface of the filter screen 110 during the disassembly path, especially in the narrow filter screen 110 storage, the hand or clothes is easy to touch the edge of the filter screen 110 and pollute the filter screen 110.
[0047] Compared with the prior art, the structure design of the circumferential air inlet and air outlet not only improves the purification efficiency, but also forms a mounting space (i.e. the open port of the top of the air inlet net) on the top of the air purifier body 100, so that the filter screen 110 can be vertically installed or taken out of the air inlet cavity along the open port of the top of the air inlet net. This installation method does not need to handle complex disassembly steps, greatly simplifies the replacement process, and prevents the user's clothes from being dirty during the disassembly process, thereby improving the use experience.
[0048] Further, the top of the filter screen 110 is provided with a top plate 111, the bottom surface of the top plate 111 is provided with an outwardly protruding positioning flange 112, the top plate 111 is arranged on the air inlet net, and the positioning flange 112 is nested with the inner wall of the air inlet net, so as to ensure that the filter screen 110 can be accurately and correctly installed on the air inlet net and kept stable, thereby reducing the risk of displacement or loosening of the filter screen 110 caused by external factors (such as movement, collision, etc.), and ensuring the stability and reliability of the equipment during operation.
[0049] In order to ensure the sealing performance between the top plate 111 and the air inlet net, a sealing ring (not shown in the figure) can also be arranged on the outer circumferential surface of the positioning flange 112 to prevent air leakage at this position and ensure that the air entering the air inlet cavity is filtered by the filter screen 110 and then output outward from the air outlet cavity.
[0050] Preferably, the air outlet base 120 is provided with an air wheel 122, which is driven to rotate by a motor 123, when the motor 123 is started, it will drive the air wheel 122 to rotate at high speed, generating strong suction to suck the uncleaned air from the surroundings (through the air inlet net) into the air inlet cavity, then, the air is guided to pass through the filter screen 110 for filtering treatment, and finally the purified air is discharged through the mesh holes on the air outlet net 140.
[0051] Further, in order to improve the air outlet efficiency, a plurality of air guide plates 124 are arranged on the inner wall of the air outlet net 140 in the embodiment, which are arranged in a central symmetry, and the air flow is effectively guided through the structural design, so that the air can be discharged with optimal path and maximum efficiency.
[0052] Specifically, the air guide plate 124 is arranged in an L-shaped structure, and the long side and the short side of the adjacent two air guide plates 124 are arranged in an inclined and parallel manner to form an air guide channel 125, and the air wheel 122 is located at the center of each air guide plate 124, which ensures that the air outlet of each air guide channel 125 is consistent, and the uniform ventilation effect is realized.
[0053] In addition, the inclined direction of the air guide channel 125 matches the rotation direction of the air wheel 122, which means that when the air wheel 122 rotates, the air flow generated by the air wheel 122 can smoothly enter the air guide channel 125 and be effectively guided and accelerated along the preset direction, greatly improving the overall air outlet efficiency of the air purifier, and through this way, not only the consistency and stability of the air flow can be ensured, but also the energy loss can be reduced, and the energy efficiency ratio of the whole system can be improved.
