Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to an air purifier. Background Technology

[0002] An air purifier is a device that can adsorb, decompose, or transform various air pollutants (such as PM2.5, dust, pollen, odors, formaldehyde, bacteria, and allergens) to effectively improve air cleanliness.

[0003] Chinese utility model patent CN214791740U discloses an air purifier with dual air ducts and multi-directional airflow, comprising: a housing; filter frames with filter modules on the left and right side panels of the housing; filter modules and air inlet plates mounted on the filter frames; a first air duct and a second air duct inside the housing; the first air duct connecting to the filter modules on the corresponding side; an upper motor impeller assembly disposed within the first air duct; and a lower motor impeller assembly disposed within the second air duct. The first and second air ducts each have their own air outlets, which can be located on the same side or different sides of the housing. Although this air purifier can achieve bidirectional airflow, its structure requires the separate configuration of filter modules on each air inlet side, resulting in a relatively complex overall structure. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, this utility model provides an air purifier.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model provides an air purifier, comprising:

[0007] A support base has an air inlet, a first air outlet, and a second air outlet on its sidewall. The first air outlet, the air inlet, and the second air outlet are arranged sequentially along the length of the support base.

[0008] A filter module is disposed in the support base, the air inlet side of the filter module is connected to the air inlet, and the filter module is used to purify the air input through the air inlet.

[0009] A first fan is disposed within the supporting base, positioned between the filter module and the first air outlet, and is used to guide the air purified by the filter module to be discharged from the first air outlet; and

[0010] The second fan is located within the support base and between the filter module and the second air outlet. The second fan is used to guide the air purified by the filter module to be discharged from the second air outlet.

[0011] This invention relates to an air purifier that, by integrating a support base and a filter module, a first fan, and a second fan located within the support base, solves the problem of complex overall structure in existing air purifiers with multi-directional airflow. Specifically, the side wall of the support base is provided with a first air outlet, an air inlet, and a second air outlet arranged sequentially along its length. The first fan is located between the filter module and the first air outlet, guiding the air purified by the filter module to be discharged from the first air outlet. The second fan is located between the filter module and the first air outlet, guiding the air purified by the filter module to be discharged from the second air outlet. During operation, the impellers of the first and second fans start simultaneously. Due to the pressure difference created by the rotation of the two impellers, indoor air is drawn from the first fan... Air is drawn into the support structure through the inlet and directly enters the filter module for filtration (removing particulate matter, odors, and harmful gases). The filtered clean air is naturally split into two airflows by the dual impellers. One airflow, driven by the impeller of the first fan, flows towards the first end of the support structure along its length and is eventually discharged from the first outlet, spreading outwards into the surrounding space. The other airflow, driven by the impeller of the second fan, flows towards the second end of the support structure along its length and is eventually discharged from the second outlet, spreading outwards into the surrounding space. This design enables the air purifier to achieve bidirectional airflow to improve airflow efficiency, while simultaneously purifying the air discharged from both the first and second air outlets using the same filter module. This reduces the number of filter modules, simplifying the overall structure of the air purifier and lowering costs. Furthermore, since the air inlet, first air outlet, and second air outlet are all located on the side wall of the support base, air enters from the first part of the side wall, flows along the length of the support base, and finally exits from the second part, forming a side-in, side-out curved flow channel. This curved flow channel forces the airflow to make at least one 90-degree turn inside, helping to reduce airflow velocity and intensity, thus reducing noise and improving the user experience. At the same time, the air outlets (including the air inlet, first air outlet, and second air outlet) are not located at the ends of the support base (such as the top of the support base), allowing the ends of the support base to be enclosed. This effectively prevents small objects such as toys and snacks from accidentally entering the air purifier, thus avoiding damage to the fan or potential safety hazards.

[0012] In one embodiment, the filter module is arranged around the centerline of the support substrate along its length direction;

[0013] The air inlets are multiple and arranged sequentially around the filter module to form a 360° omnidirectional air intake structure. This allows for 360° air intake during the operation of the first and second fans, achieving circumferential air intake. Compared to a single-sided air intake structure, this design significantly expands the air purification range and effectively reduces airflow blind spots. Furthermore, with multiple air inlets surrounding the filter module, the intake air can directly enter the filter module for filtration, avoiding ineffective circulation or stagnation within the support base. This ensures that the air is purified immediately, thereby improving filtration efficiency and overall performance.

[0014] In one embodiment, there are multiple first air outlets, which are arranged sequentially around the center line of the length direction of the supporting base to form a 360-degree all-round first air outlet structure. This structure can evenly diffuse the purified air to the surroundings, expanding the coverage of the purified air and thus effectively improving the indoor air circulation efficiency and overall purification efficiency.

[0015] In one embodiment, there are multiple second air outlets, which are arranged sequentially around the center line of the length direction of the supporting base to form a 360-degree all-round second air outlet structure. This structure can evenly diffuse the purified air to the surroundings, expanding the coverage of the purified air and thus effectively improving the indoor air circulation efficiency and overall purification efficiency.

[0016] In one embodiment, the support base further includes a first air outlet duct and a second air outlet duct. The inlet end of the first air outlet duct is connected to the first fan, and the outlet end of the first air outlet duct is connected to the first air outlet. The first air outlet duct extends obliquely so that the outlet end of the first air outlet duct is farther away from the air inlet than its inlet end, i.e., the first air outlet duct extends obliquely upward, causing the airflow to diffuse towards the upper part of the support base. This not only effectively prevents the airflow from interfering with the airflow from the outlet and the inlet, thus improving the purification efficiency, but also increases the coverage of the clean airflow, thereby improving the overall indoor air circulation and purification efficiency. In addition, it also extends the first air outlet duct, increasing the safe distance between the user and the first fan, fundamentally eliminating the risk of accidental finger contact, thereby effectively improving safety.

[0017] The inlet end of the second air outlet duct is connected to the second fan, and the outlet end of the second air outlet duct is connected to the second air outlet. The second air outlet duct extends at an angle so that the outlet end of the second air outlet duct is farther away from the air inlet than its inlet end, that is, the second air outlet duct extends obliquely downward, so that the outlet airflow diffuses towards the lower part of the supporting base. This not only effectively prevents the outlet and inlet airflows from interfering with each other and improves purification efficiency, but also increases the coverage of clean airflow, thereby improving the overall indoor air circulation and purification efficiency. In addition, it also extends the second air outlet duct, increasing the safe distance between the user and the second fan, fundamentally eliminating the risk of accidental finger contact, thereby effectively improving safety.

[0018] In one embodiment, the sidewall of the supporting base is further provided with a first non-porous portion and a second non-porous portion. The first non-porous portion is located between the air inlet and the first air outlet to separate the air inlet and the first air outlet, effectively preventing the air outlet and the air inlet from interfering with each other and improving the purification efficiency. The second non-porous portion is located between the air inlet and the second air outlet to separate the air inlet and the second air outlet, effectively preventing the air outlet and the air inlet from interfering with each other and improving the purification efficiency.

[0019] To facilitate the installation of the filter module, the first fan, and the second fan, in one embodiment, the support base includes:

[0020] The main housing has the air inlet and the receiving cavity, the receiving cavity is connected to the air inlet, the receiving cavity extends through both ends of the main housing in the length direction, and the receiving cavity accommodates the filter module;

[0021] A first support assembly is disposed at a first end along the length of the main housing, covering the first end opening along the length of the receiving cavity. The first support assembly has a first air outlet and a first air duct. The first air outlet is located on the side wall of the first support assembly, and the first air duct is located between the first air outlet and the filter module, connecting the first air outlet and the air outlet side of the filter module. The first air duct accommodates the first fan.

[0022] The second support assembly is located at the second end of the main housing along its length and covers the second end opening of the receiving cavity along its length. The second support assembly has a second air outlet and a second air duct. The second air outlet is located on the side wall of the second support assembly, and the second air duct is located between the second air outlet and the filter module. The second air duct connects the second air outlet and the air outlet side of the filter module, and the second air duct accommodates the second fan.

[0023] In one embodiment, the filter module has a central hole that extends through both ends of the filter module along its length.

[0024] The first support component is provided with a first positioning part, which is inserted into the central hole and is arranged around the center line of the central hole to position the first end of the filter module in the length direction.

[0025] The second support component is provided with a second positioning part, which is inserted into the central hole. The second positioning part is arranged around the center line of the central hole to position the second end of the filter module in the length direction, so that the filter module is stably installed in the support base.

[0026] In one embodiment, the first support component includes:

[0027] A first air guide component is disposed at the first end of the main housing along its length direction. The first air guide component covers the first end opening of the receiving cavity along its length direction. The first air guide component has a first air guide channel, which connects to the air outlet side of the filter module. The cross-section of the first air guide channel gradually increases in the direction away from the filter module.

[0028] The first support bracket is located at the first end of the length direction of the first air guide component. The first support bracket and the first air guide channel form the first air duct. The side wall of the first support bracket has the first air outlet. The first support bracket is connected to the first fan. That is, the first support component adopts a split structure composed of the first air guide component and the first support bracket. During installation, the first air guide component is first installed on the main housing, then the first fan is assembled onto the first support bracket, and finally the first support bracket is connected to the first air guide component to complete the installation of the first support component and the first fan. The installation is more flexible and convenient. At the same time, since the first air guide component has a first air guide channel with a gradually expanding cross-section, it can achieve efficient airflow guidance and uniform diffusion, thereby effectively improving the air outlet efficiency and airflow uniformity.

[0029] The second support component includes:

[0030] The second air guide component is located at the second end of the main housing along its length. The second air guide component covers the second end opening of the receiving cavity along its length. The second air guide component has a second air guide channel that connects to the air outlet side of the filter module. The cross-section of the second air guide channel gradually increases in the direction away from the filter module.

[0031] The second bracket is located at the second end of the second air guide component along its length. The second bracket and the second air guide channel form the second air duct. The side wall of the second bracket has the second air outlet. The second bracket is connected to the second fan. That is, the second support assembly adopts a split structure consisting of the second air guide component and the second bracket. During installation, the second air guide component is first installed on the main housing, then the second fan is assembled onto the second bracket, and finally the second bracket is connected to the second air guide component to complete the installation of the second support assembly and the second fan. Installation is more flexible and convenient. Simultaneously, because the second air guide component has a second air guide channel with a gradually expanding cross-section, it can achieve efficient airflow guidance and uniform diffusion, thereby effectively improving airflow efficiency and uniformity.

[0032] In one embodiment, the main housing is provided with a first limiting part, which is located in the receiving cavity. The first limiting part abuts against a first end of the filter module in the length direction to restrict the filter module from moving toward the first limiting part.

[0033] The diameter of the second end opening in the longitudinal direction of the receiving cavity is larger than the outer diameter of the filter module, and the second end opening in the longitudinal direction of the receiving cavity is used for the filter module to enter and exit the receiving cavity.

[0034] The second support assembly is provided with a second limiting part, which abuts against the second end of the filter module in the length direction to restrict the filter module from moving towards the second limiting part. The filter module is bidirectionally limited and fixed by the first limiting part of the main housing and the second limiting part of the second support assembly, effectively preventing movement of the filter module during operation and ensuring stability and reliability. Simultaneously, since the opening diameter of the second end of the receiving cavity is larger than the outer diameter of the filter module, it facilitates direct insertion and removal of the filter module, making installation and operation simple and efficient.

[0035] The beneficial effects of this utility model are:

[0036] This air purifier, by integrating a support base and a filter module, a first fan, and a second fan located within the support base, solves the problem of complex overall structure in existing air purifiers with multi-directional airflow. Specifically, the side wall of the support base is provided with a first air outlet, an air inlet, and a second air outlet arranged sequentially along its length. The first fan is located between the filter module and the first air outlet, guiding the air purified by the filter module to be discharged from the first air outlet. The second fan is located between the filter module and the first air outlet, guiding the air purified by the filter module to be discharged from the second air outlet. This allows the air purifier to achieve bi-directional airflow to improve airflow efficiency, while simultaneously purifying the air discharged from both the first and second air outlets using the same filter module. This reduces the number of filter modules, thereby simplifying the overall structure of the air purifier and lowering costs. Furthermore, because the air inlet, the first air outlet, and the second fan are arranged sequentially along the length of the support base, the air purifier can achieve bi-directional airflow. Both air outlets are located on the side wall of the support base, allowing air to enter from the first part of the side wall, flow along the length of the support base, and finally exit from the second part of the side wall, forming a side-in, side-out curved flow channel. This curved flow channel forces the airflow to make at least one 90-degree turn inside, which helps to reduce the airflow velocity and thus reduce the airflow intensity, thereby helping to reduce noise and improve the user experience. At the same time, the air outlets (including the air inlet, the first air outlet, and the second air outlet) are not located at the ends of the support base along its length (such as the top of the support base), allowing the ends of the support base to be designed as a closed structure. This effectively prevents small objects such as toys and snacks from accidentally entering the air purifier, thereby avoiding damage to the fan or potential safety hazards.

[0044] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and therefore may vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0045] Please see Figures 1-5 This invention illustrates an air purifier according to a preferred embodiment, comprising:

[0046] The support base 1 has an air inlet 111, a first air outlet 1221 and a second air outlet 1321 on its side wall. The first air outlet 1221, the air inlet 111 and the second air outlet 1321 are arranged sequentially along the length of the support base 1.

[0047] Filter module 2 is located inside the support base 1. The air inlet side of filter module 2 is connected to air inlet 111. Filter module 2 is used to purify the air input through air inlet 111.

[0048] The first fan 3 is located within the supporting base 1, between the filter module 2 and the first air outlet 1221. The first fan 3 guides the air purified by the filter module 2 to be discharged from the first air outlet 1221. Specifically, the air inlet side of the first fan 3 is connected to the air outlet side of the filter module 2, and the air outlet side of the first fan 3 is connected to the first air outlet 1221, allowing the air purified by the filter module 2 to be discharged from the first air outlet 1221 under the drive of the first fan 3.

[0049] The second fan 4 is located inside the support base 1 and between the filter module 2 and the second air outlet 1321. The second fan 4 is used to guide the air purified by the filter module 2 to be discharged from the second air outlet 1321. That is, the air inlet side of the second fan 4 is connected to the air outlet side of the filter module 2, and the air outlet side of the second fan 4 is connected to the second air outlet 1321, so that the air purified by the filter module 2 can be discharged from the second air outlet 1321 under the drive of the second fan 4.

[0050] This utility model of an air purifier, by integrating a support base 1 and a filter module 2, a first fan 3, and a second fan 4 located within the support base 1, solves the problem of complex overall structure in existing air purifiers with multi-directional airflow. Specifically, the side wall of the support base 1 is provided with a first air outlet 1221, an air inlet 111, and a second air outlet 1321 arranged sequentially along its length. The first fan 3 is located between the filter module 2 and the first air outlet 1221, and guides the air purified by the filter module 2 to be discharged from the first air outlet 1221. The second fan 4 is located between the filter module 2 and the first air outlet 1221, and guides the air purified by the filter module 2 to be discharged from the second air outlet 1321. During operation, the impellers of the first fan 3 and the second fan 4 start simultaneously. Due to the dual impellers... The rotation creates a pressure difference, drawing indoor air into the support base 1 through the air inlet 111. The air then directly enters the filter module 2 for filtration (removing particulate matter, odors, and harmful gases). The filtered clean air is naturally split into two airflows by the dual impellers. One airflow, driven by the impeller of the first fan 3, flows towards the first end of the support base 1 along its length and is eventually discharged from the first air outlet 1221, spreading into the surrounding space. The other airflow, driven by the impeller of the second fan 4, flows towards the second end of the support base 1 along its length and is eventually discharged from the second air outlet 1321. This allows the air purifier to diffuse into the surrounding space, enabling bidirectional airflow to improve efficiency. Simultaneously, it utilizes the same filter module 2 to purify air discharged from both the first air outlet 1221 and the second air outlet 1321, reducing the number of filter modules 2 and simplifying the overall structure of the air purifier, thus lowering costs. Furthermore, since the air inlet 111, the first air outlet 1221, and the second air outlet 1321 are all located on the side wall of the support base 1, air enters from the first part of the side wall of the support base 1, flows along the length of the support base 1, and finally exits from the side wall of the support base 1. The second part discharges, forming a side-in, side-out curved flow channel. This curved flow channel forces the airflow to make at least one 90-degree turn inside, which helps to reduce the airflow velocity, i.e., reduce the airflow intensity, thereby helping to reduce noise and improve the user experience. At the same time, the air outlets (including the air inlet 111, the first air outlet 1221 and the second air outlet 1321) are not arranged at the ends of the support base 1 in the length direction (such as the top of the support base 1), so that the ends of the support base 1 in the length direction can be set as a closed structure, effectively preventing small objects such as toys and snacks from accidentally entering the air purifier, thereby avoiding damage to the fan or potential safety hazards.

[0051] See Figures 1-3 In one embodiment, the length direction of the support base 1 is also... Figures 1-3 The height direction of the supporting base 1 shown.

[0052] Of course, in other embodiments, the length direction of the support base 1 can also be the transverse direction of the support base 1.

[0053] See Figures 2-3 The first fan 3 and the second fan 4 are respectively placed at both ends of the length of the filter module 2. The dual-fan structure can generate a larger total air volume and air pressure, making the air resistance to pass through the filter module 2 smaller and the purification efficiency higher. At the same time, since the air enters from the middle air inlet 111 and is simultaneously drawn by the fans at both ends, it helps to make the air pass through the entire filter module 2 more evenly, thereby making full use of the filtration area of ​​the entire filter module 2 and improving the utilization rate and overall filtration effect of the filter module 2.

[0054] See Figures 2-3 In one embodiment, the filter module 2 is arranged around the center line of the support substrate 1 along its length direction, that is, the filter module 2 is a closed cylindrical or non-closed cylindrical structure.

[0055] There are multiple air inlets 111 arranged sequentially around the filter module 2 to form a 360° all-round air intake structure. This allows air to be drawn in from all directions in 360° when the first fan 3 and the second fan 4 are running, achieving circumferential air intake. Compared with a single-sided air intake structure, this design significantly expands the air purification range and effectively reduces airflow blind spots. At the same time, with multiple air inlets 111 arranged around the filter module 2, the intake air can directly enter the filter module 2 for filtration, avoiding ineffective circulation or stagnation in the support base 1, ensuring that the air is purified as soon as possible, thereby improving filtration efficiency and overall performance.

[0056] In one embodiment, multiple air inlets 111 are evenly distributed on the side wall of the support base 1 to ensure that the air around the air purifier is drawn in evenly and synchronously, so that the purification effect is consistent in all directions. At the same time, uniform air intake means that the utilization rate of each area of ​​the corresponding filter module 2 is also consistent, avoiding the situation where some filter modules 2 are over-consumed while other areas are not utilized, thereby extending the overall service life of the filter module 2 and ensuring stable filtration efficiency.

[0057] See Figures 1-3In one embodiment, multiple air inlets 111 are arranged in an array. The array arrangement ensures the uniform coverage of the air inlets 111 on the sidewall of the support base 1, which can effectively avoid excessively strong or weak local airflow, thereby reducing turbulence or dead air zones and ensuring that air is drawn in smoothly and efficiently. In addition, on the limited sidewall area of ​​the support base 1, the array arrangement can scientifically plan the layout of the air inlets 111, which can maximize the total air intake area to reduce wind resistance, increase air volume and efficiency, and maintain the mechanical strength and integrity of the support base 1, avoiding weakening the stability of the support base 1 due to excessively large or concentrated openings.

[0058] Specifically, the above-mentioned array arrangement is a multi-row, multi-column grid structure, which regularly arranges air inlets 111 on the sidewalls of the supporting base 1 within a certain length range, thereby expanding the air intake area, improving air intake efficiency, and thus enhancing air purification efficiency.

[0059] In one embodiment, the air inlet 111 is circular, and the edges of the circular air inlet 111 are smooth, which helps to reduce wind resistance and airflow friction noise. At the same time, the circular air inlet 111 is simple to manufacture, easy to demold, and conducive to mass production and cost reduction.

[0060] Of course, in other embodiments, the air inlet 111 may also be elliptical, elongated, or other irregular shapes.

[0061] See Figures 1-3 In one embodiment, there are multiple first air outlets 1221, which are arranged sequentially around the center line of the length direction of the support base 1 to form a 360-degree all-round air outlet structure, which can evenly diffuse the purified air to the surroundings, expand the coverage of purified air, and thus effectively improve the indoor air circulation efficiency and overall purification efficiency.

[0062] In one embodiment, multiple first air outlets 1221 are evenly distributed on the side wall of the supporting base 1 to achieve 360-degree uniform and synchronous air supply, ensuring the consistency and comprehensiveness of the purification effect of the surrounding space.

[0063] See Figures 1-3 In one embodiment, multiple first air outlets 1221 are arranged in an array. The array of first air outlets 1221 is evenly distributed circumferentially on the sidewall of the support base 1, ensuring the uniformity of the coverage of the first air outlets 1221 on the sidewall of the support base 1, and ensuring that the air is discharged smoothly and efficiently. In addition, on the limited sidewall area of ​​the support base 1, the array arrangement can scientifically plan the layout of the first air outlets 1221, which can maximize the total air outlet area to reduce wind resistance, increase air volume and efficiency, and maintain the mechanical strength and integrity of the support base 1, avoiding weakening the stability of the support base 1 due to excessively large or concentrated openings.

[0064] Specifically, the above-mentioned array arrangement is a multi-row, multi-column grid structure, which regularly arranges the first air outlet 1221 on the sidewall of the supporting base 1 within a certain length range, thereby expanding the air outlet area, improving the air outlet efficiency, and thus improving the air purification efficiency.

[0065] In one embodiment, there are multiple second air outlets 1321, which are arranged sequentially around the center line of the length direction of the supporting base 1 to form a 360-degree all-round second air outlet structure, which can evenly diffuse the purified air to the surroundings, expand the coverage of purified air, and thus effectively improve the indoor air circulation efficiency and overall purification efficiency.

[0066] In one embodiment, multiple second air outlets 1321 are evenly distributed on the side wall of the supporting base 1 to achieve 360-degree uniform and synchronous air supply, ensuring the consistency and comprehensiveness of the purification effect of the surrounding space.

[0067] See Figures 1-3 In one embodiment, multiple second air outlets 1321 are arranged in an array. The array of second air outlets 1321 is evenly distributed circumferentially on the sidewall of the support base 1, ensuring the uniformity of the coverage of the second air outlets 1321 on the sidewall of the support base 1, and ensuring that the air is discharged smoothly and efficiently. In addition, on the limited sidewall area of ​​the support base 1, the array arrangement can scientifically plan the layout of the second air outlets 1321, which can maximize the total air outlet area to reduce wind resistance, increase air volume and efficiency, and maintain the mechanical strength and integrity of the support base 1, avoiding weakening the stability of the support base 1 due to excessively large or concentrated openings.

[0068] Specifically, the above-mentioned array arrangement is a multi-row, multi-column grid structure, which regularly arranges second air outlets 1321 on the sidewalls of the supporting base 1 within a certain length range, thereby expanding the air outlet area, improving the air outlet efficiency, and thus enhancing the air purification efficiency.

[0069] See Figures 2-3In one embodiment, the support base 1 further includes a first air outlet duct 1222 and a second air outlet duct 1322. The air inlet end of the first air outlet duct 1222 is connected to the first fan 3, and the air outlet end of the first air outlet duct 1222 is connected to the first air outlet 1221. The first air outlet duct 1222 extends obliquely so that the air outlet end of the first air outlet duct 1222 is farther away from the air inlet 111 than its air inlet end. That is, the first air outlet duct 1222 extends obliquely upward, so that the airflow diffuses towards the upper part of the support base 1. This not only effectively prevents the airflow from interfering with the airflow from the outlet and the airflow from the inlet, thus improving the purification efficiency, but also increases the coverage of the clean airflow, thereby improving the overall circulation and purification efficiency of indoor air. In addition, it can also extend the first air outlet duct 1222, increasing the safe distance between the user and the first fan 3, fundamentally eliminating the risk of accidental touch by fingers, thereby effectively improving safety.

[0070] The air inlet of the second air outlet duct 1322 is connected to the second fan 4, and the air outlet of the second air outlet duct 1322 is connected to the second air outlet 1321. The second air outlet duct 1322 extends at an angle so that the air outlet of the second air outlet duct 1322 is farther away from the air inlet 111 than its air inlet. That is, the second air outlet duct 1322 extends obliquely downward, so that the airflow diffuses towards the lower part of the support base 1. This not only effectively prevents the airflow from interfering with the airflow of the outlet and the airflow of the inlet, thus improving the purification efficiency, but also increases the coverage of the clean airflow, thereby improving the overall circulation and purification efficiency of indoor air. In addition, it also extends the second air outlet duct 1322, increasing the safe distance between the user and the second fan 4, fundamentally eliminating the risk of accidental touch by fingers, thus effectively improving safety.

[0071] See Figure 2 In one embodiment, the sidewall of the supporting base 1 is further provided with a first non-porous portion 113 and a second non-porous portion 114. The first non-porous portion 113 is located between the air inlet 111 and the first air outlet 1221 to separate the air inlet 111 and the first air outlet 1221, effectively preventing the air outlet and the air inlet from interfering with each other and improving the purification efficiency. The second non-porous portion 114 is located between the air inlet 111 and the second air outlet 1321 to separate the air inlet 111 and the second air outlet 1321, effectively preventing the air outlet and the air inlet from interfering with each other and improving the purification efficiency.
