Description

Technical Field

[0001] This utility model relates to an air purifier with airflow switching capability, belonging to the field of air purification technology. Background Technology

[0002] Traditional air purifiers typically employ fixed airflow paths and purification modules, making it difficult to meet the diverse needs of different users regarding airflow speed and purification effectiveness. Especially in specific scenarios, such as when gentle airflow is required to protect sensitive individuals or when strong airflow is needed to quickly purify large spaces, traditional air purifiers often struggle to meet these varied demands. This not only limits the applicability of air purifiers but also impacts user comfort and satisfaction. Therefore, an air purifier with airflow path switching capability has been proposed. Utility Model Content

[0003] The purpose of this invention is to provide an air purifier with airflow switching to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an air purifier with airflow switching capability, comprising:

[0005] Organism;

[0006] A central cavity is located inside the machine body, and an air inlet is located above the central cavity.

[0007] Fan assembly, wherein the fan assembly is disposed inside the central cavity;

[0008] The annular cavity is located inside the body and is arranged around the central cavity. Multiple purification modules are arranged inside the annular cavity, and an air outlet is arranged on one side of the annular cavity.

[0009] A through hole is provided between the central cavity and the annular cavity to connect the two cavities.

[0010] Preferably, the air outlet is provided with a speed regulating component for adjusting the wind speed, the speed regulating component including a fixed sleeve and a movable sleeve;

[0011] The fixing sleeve is fixedly connected to the air outlet;

[0012] The movable sleeve slides concentrically inside the fixed sleeve via an electric push rod;

[0013] A first air outlet is provided between the fixed sleeve and the movable sleeve, and a second air outlet is provided inside the movable sleeve. The cross-section of the first air outlet is larger than the cross-section of the second air outlet.

[0014] The first air outlet duct has a first grid plate at its outer end, which is fixed to the side wall of the fixed sleeve. The movable sleeve has a second grid plate fixedly connected to its inner end, and the holes of the first grid plate and the second grid plate are staggered.

[0015] The inner end of the fixed sleeve is concentrically fixed with a baffle by a support rod;

[0016] When the movable sleeve slides inward, the first air outlet connects with the annular cavity, and the baffle blocks the second air outlet.

[0017] When the movable sleeve slides outward, the second air outlet duct connects with the annular cavity, and the second grid plate cooperates with the first grid plate to block the first air outlet duct.

[0018] Preferably, a third grid plate is fixed to the outer end of the second air outlet duct, and the third grid plate is fixedly connected to the movable sleeve.

[0019] Preferably, multiple spiral guide plates are evenly distributed on the side wall of the second air outlet duct.

[0020] Preferably, the through hole is positioned opposite to the air outlet.

[0021] Preferably, a top cover is provided on the upper part of the body, and a fourth grid plate for covering the air inlet is provided on the top cover.

[0022] Preferably, the air inlet is provided with a filter cotton for filtering dust.

[0023] Preferably, a base is provided at the lower end of the body.

[0024] Compared with existing technologies:

[0025] 1. This invention utilizes a built-in fan assembly operating within the central cavity to effectively introduce and circulate gas. When the fan assembly is activated, external air is smoothly drawn into the air intake and quickly enters the central cavity. The optimized airflow path ensures continuous and efficient gas flow. Furthermore, a through-hole between the central cavity and the annular cavity allows the initially guided gas to smoothly enter the annular cavity. The annular cavity, serving as the air purification area, is equipped with multiple purification modules to purify the gas, ensuring the cleanliness and safety of the output gas. An air outlet on one side of the annular cavity provides a smooth discharge channel for the purified gas.

[0026] 2. This utility model achieves the adjustment of the air outlet speed through a speed regulating component. Specifically, the speed regulating component consists of a fixed sleeve and a movable sleeve, which form air outlet ducts with different cross-sections, namely a first air outlet duct and a second air outlet duct. Driven by an electric push rod, the movable sleeve can slide within the fixed sleeve, thereby selectively opening or closing different air outlet ducts.

[0027] When the movable sleeve slides inward, the second air outlet is blocked by the baffle, and the airflow can only be discharged through the first air outlet with a larger cross-section, thus slowing down the wind speed, which is suitable for scenarios requiring gentle airflow. Conversely, when the movable sleeve slides outward, the first air outlet is blocked by the first and second grid plates, and the airflow is discharged through the second air outlet with a smaller cross-section, increasing the wind speed and meeting the need for strong airflow.

[0043] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0044] Example 1

[0045] like Figures 1-6 As shown in this embodiment, an air purifier with airflow switching is provided, including a body 1, a base 13 at the lower end of the body 1, the base 13 supporting the body 1, a central cavity 2 with a built-in fan assembly 3 inside the body 1, an air inlet 201 above the central cavity 2, an annular cavity 4 inside the body 1 and surrounding the central cavity 2, a plurality of purification modules 7 inside the annular cavity 4, a through hole 6 for connecting the central cavity 2 and the annular cavity 4, and an air outlet 5 on one side of the annular cavity 4;

[0046] When the fan assembly 3 is running, external gas enters the interior of the central cavity 2 through the air inlet 201. Then, the gas in the central cavity 2 enters the interior of the annular cavity 4 through the through hole 6. The gas is processed by the purification module 7 inside the annular cavity 4 and discharged from the air outlet 5.

[0047] The through hole 6 is positioned opposite to the air outlet 5, such as Figure 3 As shown, when the gas in the central cavity 2 enters the interior of the annular cavity 4 through the through hole 6, the gas will be diverted from the through hole 6 to both sides of the annular cavity 4, and then discharged from the outlet 5, increasing the flow time of the gas in the annular cavity 4, which is beneficial for gas treatment.

[0048] Example 2

[0049] like Figure 1 and Figures 4-7 As shown, based on Embodiment 1, in order to adjust the wind speed discharged from the air outlet 5, this embodiment provides a speed regulating component 8 for adjusting the wind speed on the air outlet 5. The speed regulating component 8 includes a fixed sleeve 801 and a movable sleeve 802.

[0050] The fixing sleeve 801 is fixedly connected to the air outlet 5;

[0051] The movable sleeve 802 slides concentrically inside the fixed sleeve 801 via the electric push rod 809;

[0052] A first air outlet 803 is provided between the fixed sleeve 801 and the movable sleeve 802, and a second air outlet 804 is provided inside the movable sleeve 802. The cross-section of the first air outlet 803 is larger than the cross-section of the second air outlet 804.

[0053] The first air outlet duct 803 has a first grid plate 805 at its outer end, which is fixed to the side wall of the fixed sleeve 801. The second grid plate 806 is fixedly connected to the inner end of the movable sleeve 802. The holes of the first grid plate 805 and the second grid plate 806 are staggered.

[0054] The inner end of the fixed sleeve 801 is concentrically fixed with a baffle 807 via a support rod, and there is a gap between the baffle 807 and the fixed sleeve 801.

[0055] When the movable sleeve 802 slides inward, it slides close to the baffle 807, and the second grid plate 806 moves away from the first grid plate 805. At this time, the first air outlet 803 is connected to the annular cavity 4, and the inner end of the movable sleeve 802 will press against the side wall of the baffle 807. The baffle 807 blocks the second air outlet 804. At this time, the gas in the annular cavity 4 will be discharged from the first air outlet 803. Because the cross-section of the first air outlet 803 is large, the exhaust gas velocity is relatively slow.

[0056] When the movable sleeve 802 slides outward, it slides away from the baffle 807, and the second grid plate 806 moves closer to the first grid plate 805. At this time, the second air outlet 804 is connected to the annular cavity 4, and the inner end of the movable sleeve 802 will separate from the baffle 807. The second grid plate 806 and the first grid plate 805 cooperate to block the first air outlet 803. At this time, the gas in the annular cavity 4 will be discharged from the second air outlet 804. Because the cross-section of the second air outlet 804 is small, the exhaust gas has a relatively fast wind speed.

[0057] A third grid plate 808 is fixed to the outer end of the second air outlet duct 804. The third grid plate 808 is fixedly connected to the movable sleeve 802. Figure 4 and Figure 5 As shown, the electric push rod 809 is fixedly installed on the baffle 807, and the output shaft end of the electric push rod 809 is fixedly connected to the side wall of the third grid plate 808. When the electric push rod 809 is running, the output shaft of the electric push rod 809 can drive the movable sleeve 802 to slide.

[0058] Multiple spiral guide plates 9 are evenly distributed on the side wall of the second air outlet 804. When the gas in the annular cavity 4 is discharged from the second air outlet 804, the added spiral guide plates 9 can make the gas in the second air outlet 804 be discharged in a spiral shape, increasing the gas flow speed and enabling the gas to flow to a greater distance.

[0059] Example 3

[0060] like Figure 2As shown, based on the above embodiments, in this embodiment, a top cover 10 is provided on the top of the body 1, and a fourth grid plate 11 is provided on the top cover 10 to cover the air inlet 201. The fourth grid plate 11 effectively prevents large external particles such as dust and hair from directly entering the air inlet. Through the filtering effect of the fourth grid plate 11, the air entering the body 1 is pre-treated. At the same time, in order to further enhance the filtering effect of the air inlet, a filter cotton 12 is also provided inside the air inlet 201. The filter cotton 12 can further block and adsorb small particles in the air, ensuring that the air entering the body is cleaner.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
