[0002] Air handling units (ATUs) are widely used as important devices for improving indoor air quality. The working principle of an ATU is as follows: air flows into the unit through the inlet, is purified by filters, and then discharged through the outlet, thus improving air quality. However, due to unreasonable structural design, some ATUs may discharge air that has not been purified by the filters, thereby affecting the purification effect. Utility Model Content

[0006] For example, the baffle is located between the air guide structure and the housing, and connects the outer peripheral wall of the air guide structure and the inner wall of the housing.

[0007] For example, the partition is a first sealing element, which is sleeved on the outer periphery of the air guide structure and connected to the outer shell.

[0008] For example, the air handling equipment further includes: an air outlet structure connected to the air outlet of the housing; an air guide structure including a first air guide structure and a second air guide structure connected to each other, the first air guide structure also being connected to the air outlet structure, the second air guide structure also being connected to the air inlet structure, a baffle located between the first air guide structure and the housing, and / or, the baffle located between the second air guide structure and the housing.

[0009] For example, the air handling equipment further includes a second seal disposed between the air inlet structure and the air guide structure to seal the gap between the air inlet structure and the air guide structure.

[0010] For example, the air handling equipment further includes: an annular mounting bracket disposed between the housing and the air inlet structure and connected to the air inlet structure, and the top of the filter element being connected to the annular mounting bracket;

[0011] The air handling unit also includes a third seal, which is disposed between the annular mounting bracket and the filter element to seal the gap between the annular mounting bracket and the filter element.

[0012] For example, the annular mounting bracket and the air inlet structure are an integral structure, or the annular mounting bracket and the air inlet structure are separate structures, and the third seal is also provided between the annular mounting bracket and the air inlet structure to seal the gap between the annular mounting bracket and the air inlet structure.

[0013] For example, the annular mounting bracket divides the interior of the housing into a first chamber and a second chamber, the filter is located in the first chamber, the air guide structure is located in the second chamber, the two ends of the air inlet structure are located in the first chamber and the second chamber respectively, and the air inlet includes a first air inlet located on the housing in the first chamber; wherein, the annular mounting bracket is spaced apart from or detachably connected to the housing, and the air passing through the through hole can flow through the gap between the annular mounting bracket and the housing to the first flow channel.

[0014] For example, the housing includes a first housing and a second housing connected together, a first air inlet is opened in the first housing, an annular mounting bracket is spaced apart from or connected to the first housing, a through hole is located at the connection position of the first housing and the second housing, and / or, the second housing is provided with a through hole.

[0017] The air handling device provided in this embodiment of the invention, under the action of the air guiding component, allows air to flow from the air inlet to the air outlet. During this flow, the air passes through a filter element, which purifies and filters the air, improving the cleanliness of the air discharged from the outlet and thus enhancing air quality, allowing users to breathe fresh air. By setting a baffle between the through-hole and the air outlet, when air passes through the through-hole, the baffle ensures that the air entering through the through-hole is filtered before being discharged from the outlet. This reduces the possibility of unfiltered air passing through the through-hole and increases the likelihood of filtered air being discharged from the outlet, thereby improving the cleanliness of the air discharged from the outlet, effectively improving air quality, and enhancing the purification effect and efficiency of the air purifier.

Detailed Implementation

[0032] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment of the present invention provides an air handling device 100, including: an air inlet 111 and an air outlet 112; an air guide assembly for guiding air from the air inlet 111 toward the air outlet 112; a filter element 120 disposed between the air inlet 111 and the air outlet 112 for filtering the air flowing through the air inlet 111 and the air outlet 112; a through hole 1112 for transmitting signals, including light signals and / or odor signals; and a baffle 130 disposed between the through hole 1112 and the air outlet 112. When air passes through the through hole 1112, the baffle 130 is used to ensure that the air entering from the through hole 1112 is filtered by the filter element 120 and discharged from the air outlet 112.

[0034] The signal transmitted through the through-hole 1112 may include either a light signal or an odor signal, or both. It is understood that the air handling device 100 may also include an air quality sensor 210, which is used to emit light signals and / or odor signals, or to receive light signals and / or odor signals. The through-hole 1112 allows the light signals and / or odor signals to be transmitted, thereby improving the measurement accuracy of the air sensor. Alternatively, the air handling device 100 may also include a light display component, which can be used to indicate the air quality of the space where the air handling device 100 is located, or to indicate other interactive information. The light display component can be used to emit or receive light signals, and the through-hole 1112 allows the light signals to be transmitted, thereby improving the display effect of the light display component.

[0035] The air handling device 100 provided in this embodiment of the utility model allows air to flow from the air inlet 111 to the air outlet 112 under the action of the air guide component. During the process of air flowing from the air inlet 111 to the air outlet 112, the air passes through the filter element 120. The filter element 120 purifies and filters the air, which can improve the cleanliness of the air discharged through the air outlet 112, thereby improving air quality and allowing users to breathe fresh air. By providing a baffle 130 between the through hole 1112 and the air outlet 112, when air passes through the through hole 1112, the baffle 130 is used to ensure that the air entering from the through hole 1112 is filtered by the filter element 120 and then discharged from the air outlet 112. This reduces the possibility that the air passing through the through hole 1112 will be discharged from the air outlet 112 without passing through the filter element 120, and increases the possibility that the air discharged from the air outlet 112 will pass through the filter element 120, thereby improving the cleanliness of the air discharged from the air outlet 112, effectively improving air quality, and improving the purification effect and efficiency of the air purifier.

[0036] Furthermore, since the baffle 130 is located between the through hole 1112 and the air outlet 112, the baffle 130 can achieve air isolation by contacting the inner wall of the flow channel between the air inlet 111 and the air outlet 112. Compared with the baffle 130 being located at the air outlet 112, the contact area between the baffle 130 and the inner wall of the flow channel can be increased, resulting in a good isolation effect.

[0037] Furthermore, the air handling equipment 100 also includes a housing 110, which has an air inlet 111 and an air outlet 112; an air guide assembly is disposed inside the housing 110, a filter element 120 is disposed inside the housing, and a baffle element 130 is disposed inside the housing.

[0038] Understandably, the interior of the outer casing 110 can be provided with a first flow channel 113. Air flowing into the interior of the outer casing 110 through the air inlet 111 can flow through the first flow channel 113 to the exterior of the outer casing 110 through the air outlet 112. The filter element 120 is located within the first flow channel 113. That is, the air flowing into the interior of the outer casing 110 through the air inlet 111 is filtered by the filter element 120 and then discharged through the air outlet 112. This portion of air has high cleanliness due to the purification effect of the filter element 120. Without the baffle 130, the air flowing into the interior of the outer casing 110 through the through hole 1112 is discharged through the air outlet 112 from the exterior of the first flow channel 113. This portion of air, since it has not been purified by the filter element 120, is still dirty air and has low cleanliness. If it is discharged directly through the air outlet 112, it will reduce the purification effect of the air purifier. Therefore, in this embodiment of the invention, a baffle 130 is provided between the through hole 1112 and the air outlet 112. The baffle 130 blocks the air flowing from the through hole 1112 to the air outlet 112, thus preventing the air flowing from the through hole 1112 to the air outlet 112 from flowing to the filter element 120. This allows the air to be purified by the filter element 120 and then discharged from the air outlet 112. This reduces the possibility that the air flowing into the housing 110 through the through hole 1112 will be discharged directly from the air outlet 112 without passing through the filter element 120. As a result, the air discharged from the air outlet 112 is the air that has passed through the filter element 120, improving the cleanliness of the air discharged from the air outlet 112, improving air quality, and enhancing the purification effect and efficiency of the air purifier.

[0039] In the above embodiments, the filter element 120 can be a filter screen, filter cotton, etc. Specifically, the filter element 120 can be a HEPA (High-Efficiency Particulate Air) filter screen.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the air outlet 112 is located at the top of the housing 110, and the air inlet 111 is located at the side of the housing 110. For example, if the housing 110 is a barrel-shaped structure, the top of the barrel-shaped structure is configured as the air outlet 112, and the side of the barrel-shaped structure is configured as the air inlet 111. The air guiding assembly includes an air inlet structure 140 and an air guiding structure 150 connected to each other. The air inlet structure 140 is located below the air guiding structure 150, that is, the air guiding structure 150 is located on the side of the air inlet structure 140 near the air outlet 112. The filter element 120 is located between the air inlet 111 and the air inlet structure 140. The housing 110, the inner wall of the air inlet structure 140, and the inner wall of the air guiding structure 150 together form a first flow channel 113, and the filter element 120 is disposed in the first flow channel 113.

[0041] Therefore, the air flowing into the housing 110 through the air inlet 111 flows through the filter element 120 to the air intake structure 140, and is discharged from the air outlet 112 through the inner wall of the air intake structure 140 and the inner wall of the air guide structure 150, so as to realize the circulation of air in the first flow channel 113. Figure 4 The solid arrows in the diagram indicate the direction of air flow through the first flow channel 113. This portion of air is purified by passing through the filter element 120, resulting in high cleanliness.

[0042] Without the baffle 130, air flowing into the housing 110 through the through hole 1112 will flow to the outlet 112 via the outer wall of the air inlet structure 140 and the outer wall of the air guide structure 150. Figure 4 The dashed arrows in the diagram indicate the direction of airflow into the housing 110 through the through-hole 1112. It is understood that if the baffle 130 is not provided, the air passing through the through-hole 1112 will be discharged along the outlet 112, as... Figure 4 As shown by the dotted line arrow. In this embodiment, because a baffle 130 is provided between the through hole 1112 and the air outlet 112, it can prevent the air passing through the through hole 1112 from being discharged to the air outlet 112, so that the air passing through the through hole 1112 flows to the first flow channel 113 and flows through the filter element 120. That is, in actual application scenarios, due to the setting of the baffle 130, the air flowing into the housing 110 from the through hole 1112 will not be discharged as... Figure 4 The air is discharged from outlet 112 as indicated by the arrow drawn at the midpoint.

[0043] like Figure 3 , Figure 5 and Figure 8As shown, in some embodiments, the baffle 130 is located between the air guide structure 150 and the outer casing 110, and connects the outer peripheral wall of the air guide structure 150 and the inner wall of the outer casing 110. Thus, the baffle 130 can block the space formed between the air guide structure 150 and the outer casing 110 at the position between the through hole 1112 and the air outlet 112, so as to prevent the air passing through the through hole 1112 from continuing to flow to the air outlet 112. This allows the air passing through the through hole 1112 to flow to the filter element 120 of the first flow channel 113 under the guidance of the outer wall of the air inlet structure 140, reducing the possibility that the air passing through the through hole 1112 will be discharged directly from the air outlet 112 without passing through the filter element 120. This ensures that the air discharged from the air outlet 112 is the air that has passed through the filter element 120, improving the cleanliness of the air discharged from the air outlet 112, improving air quality, and improving the purification effect of the air purifier.

[0044] Furthermore, since the outer periphery of the air guide structure 150 and the inner wall of the outer casing 110 are smooth and have a large area, connecting the outer periphery of the air guide structure 150 and the inner wall of the outer casing 110 with the partition 130 can maximize the contact area between the partition 130 and the outer wall of the air guide structure 150, as well as the contact area between the partition 130 and the inner wall of the outer casing, thereby improving the blocking effect of the partition 130. Simultaneously, placing the partition 130 between the air guide structure 150 and the outer casing 110 facilitates the assembly of the partition 130.

[0045] Understandably, in other examples, the baffle 130 may also be located between the air intake structure 140 and the housing 110, and connect the outer peripheral wall of the air intake structure 140 and the inner wall of the housing 110.

[0046] like Figure 5 and Figure 8 As shown, in some embodiments, the partition 130 is a first sealing element, which is sleeved on the outer periphery of the air guide structure 150 and connected to the outer shell 110.

[0047] In this embodiment, the partition 130 is configured as a first sealing element. This first sealing element seals the gap between the outer wall of the air guide structure 150 and the inner wall of the outer casing 110. This effectively blocks the space between the outer wall of the air guide structure 150 and the inner wall of the outer casing 110, preventing air passing through the through hole 1112 from flowing further towards the outlet 112. Instead, the air passing through the through hole 1112 flows towards the first flow channel 113 and then through the filter element 120. The first sealing element is a standard component, simple in structure, low in cost, easy to install, and easy to implement, thus simplifying the manufacturing cost of the partition 130. Furthermore, this configuration facilitates the assembly of the first sealing element with the air guide structure 150 and the outer casing 110.

[0048] It is understandable that the number of first seals can be one, two, or more. A larger number of first seals have higher sealing and barrier effects, which can further reduce the possibility that the air passing through the through hole 1112 will flow to the air outlet 112 through the barrier 130, thus having a higher barrier effect.

[0049] It is understood that the first sealing element can be sleeved on the outer peripheral side of the end of the air guide structure 150 near the air outlet 112, and connect the outer wall of the air guide structure 150 and the inner wall of the outer shell 110; or, the first sealing element can be sleeved on the outer peripheral side of the end of the air guide structure 150 near the air inlet structure 140, and connect the outer wall of the air guide structure 150 and the inner wall of the outer shell 110; or, the first sealing element can be sleeved on the outer peripheral side between the end of the air guide structure 150 near the air outlet 112 and the end near the air inlet structure 140, and connect the outer wall of the air guide structure 150 and the inner wall of the outer shell 110.

[0050] Specifically, when there are two or more first seals, the positions of the multiple first seals can be the same or different. Specifically, the first seals can be sealing rings, sealant, sealing cotton, etc.

[0051] like Figure 3 , Figure 4 and Figure 8 As shown, in some embodiments, the air handling device 100 further includes: an air outlet structure 160, which is connected to the air outlet 112 of the housing 110, i.e., the air outlet structure 160 is connected to the housing 110 and covers the air outlet 112; an air guide structure 150 includes a first air guide structure 151 and a second air guide structure 152, the first air guide structure 151 is connected to the air outlet structure 160 and the second air guide structure 152, the second air guide structure 152 is also connected to the air inlet structure 140; the air outlet 112 includes a first air outlet 1121 and a second air outlet 1122, the first air outlet 1121 is covered by the air outlet structure 160; the air outlet structure 160 is provided with an air passage communicating with the first flow channel 113; and the second air outlet 1122 is a gap at the connection position between the air outlet structure 160 and the housing 110.

[0052] In this embodiment, the air outlet structure 160 covers the air outlet 112 of the outer casing 110, and the air outlet structure 160 is provided with an airflow channel for air to pass through. The air guide structure 150 includes a first air guide structure 151 and a second air guide structure 152 located between the air outlet structure 160 and the air inlet structure 140. The first air guide structure 151 is located between and connects the air outlet structure 160 and the second air guide structure 152, and the second air guide structure 152 connects the first air guide structure 151 and the air inlet structure 140. Thus, the first air guide structure 151 and the second air guide structure 152 are used to connect the air inlet structure 140 and the air outlet structure 160 and guide the air. It can be understood that the inner walls of the first air guide structure 151 and the second air guide structure 152 are located within the first flow channel 113.

[0053] The air outlet 112 includes a first air outlet 1121 and a second air outlet 1122. It can be understood that the air outlet 112 of the outer shell 110 is divided into a first air outlet 1121 and a second air outlet 1122 by the air outlet structure 160. The first air outlet 1121 is covered by the air outlet structure 160. The air passage on the air outlet structure 160 is connected to the first flow channel 113. The second air outlet 1122 is the gap at the connection between the air outlet structure 160 and the outer shell 110.

[0054] Therefore, as Figure 4 As shown, after air flows into the outer casing 110 through the air inlet 111, the air in the first flow channel 113 is purified by the filter element 120 and then flows into the interior of the air intake structure 140. Under the guidance of the second air guide structure 152 and the first air guide structure 151, the air flows from inside the second air guide structure 152 and the first air guide structure 151 to the air outlet structure 160, and is discharged through the air passage of the air outlet structure 160 and the first air outlet 1121, so that the user can breathe fresh air. At the same time, the arrangement of the air outlet structure 160 can improve the uniformity and stability of the discharged air, and improve the comfort of the user.

[0055] After air flows into the outer casing 110 through the through hole 1112, it tends to flow towards the second air outlet 1122 after passing through the outer wall of the air inlet structure 140, the outer wall of the second air guide structure 152, and the outer wall of the first air guide structure 151. If the baffle 130 is not provided, this unpurified air will be directly discharged from the second air outlet 1122, which will affect the purification effect of the air handling equipment 100. Therefore, in this embodiment of the present invention, a baffle 130 is provided between the outer wall of the air guide structure 150 and the inner wall of the outer casing 110. The baffle 130 can block the air passing through the through hole 1112 from flowing to the second air outlet 1122, so that the air passing through the through hole 1112 flows to the first flow channel 113 and flows through the filter element 120.

[0056] In the above embodiments, such as Figure 3 , Figure 5 , Figure 8 As shown, the baffle 130 is located between the first air guide structure 151 and the outer casing 110, and connects the outer peripheral wall of the first air guide structure 151 and the inner wall of the outer casing 110. Thus, the baffle 130 isolates the space between the first air guide structure 151 and the outer casing 110, preventing air passing through the through hole 1112 from continuing to flow to the second air outlet 1122. This allows the air passing through the through hole 1112 to flow towards the filter element 120 of the first flow channel 113, guided by the outer wall of the second air guide structure 152 and the outer wall of the air inlet structure 140. Specifically, the baffle 130 is positioned away from the air outlet 112 to facilitate its assembly, such as when the baffle 130 is located on the outer peripheral side of the portion of the first air guide structure 151 near the second air guide structure 152.

[0057] In the above embodiments, the baffle 130 may also be located between the second air guide structure 152 and the outer shell 110, and connect the outer peripheral wall of the second air guide structure 152 and the inner wall of the outer shell 110. Thus, the space between the second air guide structure 152 and the outer shell 110 is separated by the baffle 130 to prevent the air passing through the through hole 1112 from continuing to flow to the second air outlet 1122, so that the air passing through the through hole 1112 flows to the filter 120 of the first flow channel 113 under the guidance of the outer wall of the air inlet structure 140.

[0058] In the above embodiments, there can be multiple partitions 130. Some partitions 130 are located between the first air guide structure 151 and the outer shell 110 and are connected to the outer peripheral wall of the first air guide structure 151 and the inner wall of the outer shell 110. Other partitions 130 are located between the second air guide structure 152 and the outer shell 110 and are connected to the outer peripheral wall of the second air guide structure 152 and the inner wall of the outer shell 110. This allows the space between the outer wall of the outer shell 110 and the inner wall of the air guide structure 150 to be blocked at different locations, achieving a multi-barrier effect. This further improves the reliability of preventing air passing through the through hole 1112 from being discharged through the second air outlet 1122.

[0059] like Figure 3As shown, in some embodiments, the air handling device 100 further includes a fan wheel 170, which is disposed within a first flow channel 113. The fan wheel 170 is connected to the air guide structure 150 and located on the side of the air guide structure 150 facing the air inlet structure 140. For example, the fan wheel 170 is connected to a second air guide structure 152 and located on the side of the second air guide structure 152 facing the air inlet structure 140. The fan wheel 170 is used to generate driving air circulation so that air from the external environment flows into the housing 110 through the air inlet 111 and is discharged to the external environment through the air outlet 112 via the first flow channel 113. Since the air discharged to the external environment is purified by the filter element 120, the user can breathe fresh air.

[0060] like Figure 3 and Figure 6 As shown, in some embodiments, the air handling device 100 further includes a second seal 180 disposed between the air inlet structure 140 and the air guide structure 150 to seal the gap between the air inlet structure 140 and the air guide structure 150.

[0061] In this embodiment, the provision of the second sealing element 180 can reduce the possibility of air leakage at the connection between the air inlet structure 140 and the air guide structure 150, and improve the sealing performance at the connection between the air inlet structure 140 and the air guide structure 150.

[0062] Since the inner walls of the air inlet structure 140 and the air guide structure 150 are located inside the first flow channel 113, while the through hole 1112 is located outside the first flow channel 113, sealing the gap at the connection between the air inlet structure 140 and the air guide structure 150 with the second sealing element 180 can reduce the possibility of air leakage between the air inlet structure 140 and the air guide structure 150. This can reduce the possibility of air passing through the through hole 1112 flowing into the first flow channel 113 through the gap at the connection between the air inlet structure 140 and the air guide structure 150, thus polluting the purified air in the first flow channel 113. It can also reduce the possibility of air leakage after purification in the first flow channel 113, thereby reducing the air volume of purified air. This effectively improves the cleanliness of the air discharged through the air outlet 112 and gives the air outlet 112 a larger air volume, thereby improving the purification effect and purification efficiency of the air handling equipment 100.

[0063] Specifically, the second seal 180 can be a sealing ring, sealant, sealing cotton, etc. The second seal 180 is disposed between the air inlet structure 140 and the second air guide structure 152.

[0064] like Figure 3 , Figure 7 , Figure 9 and Figure 10As shown, in some embodiments, the air handling device 100 further includes: an annular mounting bracket 190 disposed between the housing 110 and the air inlet structure 140 and connected to the air inlet structure 140; the top end of the filter element 120 is connected to the annular mounting bracket 190; the air handling device 100 further includes a third seal 200 disposed between the annular mounting bracket 190 and the filter element 120 to seal the gap between the annular mounting bracket 190 and the filter element 120.

[0065] In this embodiment, the annular mounting bracket 190 provides reliable support for the filter element 120. Thus, the top of the filter element 120 is connected to the annular mounting bracket 190, which is connected to the air inlet structure 140. This allows the filter element 120 to be fixed on the air inlet structure 140 and located between the outer casing 110 and the air inlet structure 140. By providing a third seal 200 between the annular mounting bracket 190 and the filter element 120, the third seal 200 seals the gap between the annular mounting bracket 190 and the filter element 120. This reduces the possibility of air leakage between the annular mounting bracket 190 and the filter element 120, and reduces the possibility of dirty air from the side of the filter element 120 away from the air inlet structure 140 flowing through the gap between the filter element 120 and the annular mounting bracket 190 to the side of the filter element 120 closer to the air inlet structure 140 and contaminating the purified air. This allows the dirty air from the side of the filter element 120 away from the air inlet structure 140 to flow more comprehensively through the filter element 120 into the interior of the air inlet structure 140, thereby improving the purification effect of the air handling equipment 100.

[0066] The third sealing element 200 can be a sealing ring, sealing cotton, sealing adhesive, etc.

[0067] In the above embodiments, the filter element 120 and the annular mounting bracket 190 are detachably connected, facilitating the disassembly and separation of the filter element 120 and the annular mounting bracket 190 for maintenance, cleaning, and replacement. This improves maintenance efficiency, cleaning efficiency, and replacement efficiency, and helps save on replacement costs. Specifically, the filter element 120 and the annular mounting bracket 190 can be detachably connected via at least one of the following structures: bolt structure, snap-fit ​​structure, plug-in structure, tenon structure, and magnetic structure. It is understood that in some examples, the filter element 120 and the annular mounting bracket 190 can also be fixedly connected using adhesives or the like.

[0068] like Figure 9 and Figure 10As shown, in some embodiments, the annular mounting bracket 190 and the air inlet structure 140 are integrated, which simplifies the assembly operation of the annular mounting bracket 190 and the air inlet structure 140, and helps to improve the assembly efficiency of the air handling equipment 100 and increase production efficiency. At the same time, the integrated structure of the annular mounting bracket 190 and the air inlet structure 140 improves the reliability of the connection between the annular mounting bracket 190 and the air inlet structure 140, reduces the possibility of gaps at the connection point, improves the sealing of the first flow channel 113, and helps to improve the purification effect of the air handling equipment 100.

[0069] like Figure 3 , Figure 7 As shown, in some embodiments, the annular mounting bracket 190 and the air inlet structure 140 are separate structures, and the third seal 200 is also disposed between the annular mounting bracket 190 and the air inlet structure 140 to seal the gap between the annular mounting bracket 190 and the air inlet structure 140.

[0070] In this embodiment, the annular mounting bracket 190 and the air inlet structure 140 are separate structures. This makes it convenient to disassemble and separate the annular mounting bracket 190 and the air inlet structure 140 for maintenance and replacement, which helps to improve maintenance efficiency and save replacement costs.

[0071] In this case, the third seal 200 is not only disposed between the annular mounting bracket 190 and the filter element 120 to seal the gap between the annular mounting bracket 190 and the filter element 120, but also disposed between the annular mounting bracket 190 and the air inlet structure 140 to seal the gap between the annular mounting bracket 190 and the air inlet structure 140. Therefore, by using the third seal 200, it is possible to reduce the flow of dirty air from the side of the filter 120 away from the air inlet structure 140 through the gap between the filter 120 and the annular mounting bracket 190 to the side of the filter 120 closer to the air inlet structure 140, and also to reduce the possibility of dirty air from the side of the annular mounting bracket 190 away from the filter 120 flowing through the gap between the annular mounting bracket 190 and the air inlet structure 140 to the side of the filter 120 closer to the air inlet structure 140. In other words, it is possible to reduce the possibility of unpurified dirty air flowing to the air inlet structure 140 without passing through the filter 120, so that dirty air can flow more comprehensively through the filter 120 to the interior of the air inlet structure 140, thereby improving the purification effect of the air handling equipment 100.

[0072] Furthermore, the annular mounting bracket 190 is detachably connected to the air inlet structure 140, facilitating disassembly and separation for maintenance and parts replacement, thereby improving maintenance efficiency and saving replacement costs. Specifically, the annular mounting bracket 190 and the air inlet structure 140 can be detachably connected via at least one of the following methods: bolt structure, snap-fit ​​structure, plug-in structure, tenon and mortise structure, and magnetic structure. It is understood that in some examples, the annular mounting bracket 190 and the air inlet structure 140 can also be fixedly connected using adhesives or similar methods.

[0073] In some examples, the annular mounting bracket 190 can be connected to the housing 110, or the annular mounting bracket 190 can be spaced apart from the housing 110. Specifically, the annular mounting bracket 190 can be detachably connected to the housing 110 to facilitate disassembly and separation for maintenance and parts replacement, thereby improving maintenance efficiency and saving replacement costs. Specifically, the annular mounting bracket 190 and the housing 110 can be detachably connected via at least one of the following methods: bolt structure, snap-fit ​​structure, plug-in structure, tenon structure, and magnetic structure. It is understood that in some examples, the annular mounting bracket 190 and the housing 110 can also be fixedly connected via adhesive or the like.

[0074] In some embodiments, such as Figure 3 and Figure 9 As shown, the annular mounting bracket 190 divides the interior of the housing 110 into a first chamber 115 and a second chamber 116. The filter element 120 is located in the first chamber 115, and the air guide structure 150 is located in the second chamber 116, i.e., the first chamber 115 is located below the second chamber 116. The two ends of the air inlet structure 140 are located in the first chamber 115 and the second chamber 116 respectively, so that the first chamber 115 and the second chamber 116 can be connected by the air inlet structure 140. The air inlet 111 includes a first air inlet 1111 located on the housing 110 in the first chamber 115. It can be understood that, as Figure 9 and Figure 10 As shown, when the annular mounting bracket 190 and the outer casing 110 are arranged at intervals, the air passing through the through hole 1112 can flow through the gap between the annular mounting bracket 190 and the outer casing 110 to the first flow channel 113. That is, the first flow channel 113 and the through hole 1112 can be connected through the gap indirectly formed between the annular mounting bracket 190 and the outer casing 110. Figure 3 and Figure 7 As shown, when the annular mounting bracket 190 is detachably connected to the housing 110, the air passing through the through hole 1112 can flow through the gap between the annular mounting bracket 190 and the housing 110 to the first flow channel 113. That is, the first flow channel 113 and the through hole 1112 can be connected through the gap at the connection position between the annular mounting bracket 190 and the housing 110.

[0075] Thus, the inner wall of the outer shell 110 corresponding to the first chamber 115, the outer wall of the air inlet structure 140 in the first chamber 115, the inner wall of the air inlet structure 140, and the inner wall of the air guide structure 150 together form the first flow channel 113, so that air flows into the first chamber 115 through the first air inlet 1111, is purified by the filter element 120 of the first chamber 115, and is discharged from the air outlet 112 through the interior of the air outlet structure 160 and the air guide structure 150, so as to realize the circulation of air in the first flow channel 113.

[0076] Air passing through the through hole 1112 flows into the first chamber 115, then flows into the second chamber 116 through the gap between the annular mounting bracket 190 and the outer shell 110, and flows to the air outlet 112 through the outer wall of the air inlet structure 140 and the outer wall of the air guide structure 150. Understandably, due to the arrangement of the baffle 130, such as the baffle 130 being located in the second chamber 116 and between the outer wall of the air guide structure 150 and the inner wall of the outer casing 110, it can prevent the possibility of air passing through the through hole 1112 flowing to the air outlet 112. This allows the air passing through the through hole 1112 to flow into the first flow channel 113 through the gap between the annular mounting bracket 190 and the outer casing 110, and then be purified by the filter 120 of the first chamber 115 before being discharged from the first air outlet 1121 through the interior of the air outlet structure 160 and the air guide structure 150. This improves the cleanliness of the air discharged from the air outlet 112, enhances the air quality of the external environment, and allows users to breathe fresh air.

[0077] In some embodiments, the housing 110 includes a first housing 117 and a second housing 118 connected together, wherein the first housing 117 and the second housing 118 can be an integral structure or a separate structure. Specifically, by configuring the housing 110 as a detachably connected first housing 117 and second housing 118, the assembly of the housing 110 can be facilitated, thereby facilitating the assembly of the air inlet structure 140, air guide structure 150, and air outlet structure 160 located within the housing 110 with the housing 110, which is beneficial to improving the assembly efficiency of the air purification equipment. Specifically, the first housing 117 and the second housing 118 can be detachably connected by at least one of the following structures: bolt structure, plug-in structure, snap-fit ​​structure, tenon and mortise structure, and magnetic attraction structure. By configuring the first housing 117 and the second housing 118 as an integral structure, the assembly operation of the first housing 117 and the second housing 118 is simplified, which is beneficial to improving the assembly efficiency and production efficiency of the housing 110, thereby improving the production efficiency of the air handling equipment.

[0078] In the above embodiment, the first air inlet 1111 is opened in the first outer shell 117, that is, the first outer shell 117 is located below the second outer shell 118. The annular mounting bracket 190 is spaced apart from or connected to the inner wall of the first outer shell 117, so that the bottom of the annular mounting bracket 190 and the first outer shell 117 enclose the first chamber 115. Therefore, compared with the connection between the annular mounting bracket 190 and the second outer shell 118, and the bottom of the annular mounting bracket 190, part of the second outer shell 118, and part of the first outer shell 117 enclose the first chamber 115, the number of components enclosing the first chamber 115 is reduced. As a result, the gaps in the first chamber 115 can be reduced, the possibility of air leakage in the first chamber 115 can be reduced, and the sealing performance of the first chamber 115 can be improved.

[0079] In the above embodiment, the through hole 1112 is located on the outer shell 110 of the second chamber 116. Thus, air from the external environment flows into the second chamber 116 through the through hole 1112, then flows through the outer wall of the air inlet structure 140 and the outer wall of the air guide structure 150 to the air outlet 112. Due to the partition 130, the possibility of air passing through the through hole 1112 flowing to the air outlet 112 is prevented, allowing the air passing through the through hole 1112 to flow into the first flow channel 113 through the gap between the annular mounting bracket 190 and the outer shell 110. After being purified by the filter 120 of the first chamber 115, the air is discharged through the interior of the air outlet structure 160 and the air guide structure 150 from the first air outlet 1121, thereby improving the cleanliness of the air discharged from the air outlet 112, improving the air quality of the external environment, and allowing the user to breathe fresh air.

[0080] In the above embodiments, the through hole 1112 is located at the connection position of the first outer shell 117 and the second outer shell 118, and / or, the second outer shell 118 is provided with the through hole 1112.

[0081] The gap at the connection point of the first outer shell 117 and the second outer shell 118 forms a through hole 1112, allowing air from the external environment to flow into the second chamber 116 through the gap at the connection point of the first outer shell 117 and the second outer shell 118. In other words, the through hole 1112 can be the installation gap between the first outer shell 117 and the second outer shell 118, that is, the through hole 1112 can be formed during the assembly process.

[0082] The second outer shell 118 has a through hole 1112, which allows air from the external environment to flow into the second chamber 116 through the through hole 1112 on the second outer shell 118. That is to say, the through hole 1112 can be machined.

[0083] In this embodiment, the through hole 1112 may be formed during the assembly of the first outer shell 117 and the second outer shell 118, or the through hole 1112 may be formed during the assembly of the first outer shell 117 and the second outer shell 118, or the through hole 1112 may be formed during the assembly of the first outer shell 117 and the second outer shell 118, or the through hole may be formed during the assembly of the second outer shell 118.

[0084] like Figure 3 and Figure 8 As shown, in some embodiments, the air handling device 100 further includes an air quality sensor 210, which is used to detect the air quality of the external environment. The air quality sensor 210 is installed inside the second chamber 116, opposite to a through hole 1112 in the second housing 118. The through hole 1112 allows the detection signal of the air quality sensor 210 to pass through, thereby enabling the air quality sensor 210 to accurately measure the air quality of the external environment. That is, since the second housing 118 has a through hole 1112 for the detection signal of the air quality sensor 210 to pass through, there is a possibility that air from the external environment may flow into the housing 110 through the through hole 1112. If the baffle 130 is not provided, the air flowing into the housing 110 from the through hole 1112 will flow towards the air outlet 112 (such as the second air outlet 1122) through the outer wall of the air inlet structure 140 and the outer wall of the air guide structure 150. There is a possibility that unpurified air will be discharged through the second air outlet 1122. Therefore, in the embodiments provided by this utility model, in the air outlet 1122, the air quality sensor 210 is installed inside the second chamber 116, opposite to a through hole 1112 in the second housing 118. A partition 130 is provided between the outer wall of the air structure 150 and the inner wall of the second outer shell 118, so that the air flowing into the outer shell 110 from the through hole 1112 will flow into the first flow channel 113 through the gap at the connection position between the annular mounting bracket 190 and the first outer shell 117, and then be purified by the filter 120 of the first flow channel 113 before being discharged from the first air outlet 1121 through the interior of the air outlet structure 160 and the air guide structure 150. This improves the cleanliness of the air discharged from the air outlet 112, improves the air quality of the external environment, and allows users to breathe fresh air. Specifically, the air quality sensor 210 can be installed on the annular mounting bracket 190, or the air quality sensor 210 can be installed on the outer wall of the air outlet structure 160. It is understood that the air quality sensor 210 can be directly or indirectly installed on the annular mounting bracket 190 through a mounting plate, or the air quality sensor 210 can be directly or indirectly installed on the outer wall of the air outlet structure 160 through a mounting plate.

[0085] In some embodiments, the air handling device 100 further includes: a light display component, installed in the second chamber 116, opposite to a through hole 1112 in the second housing 118, the through hole 1112 being used to transmit light signals. This allows the light signal from the light display component to be projected to the outside of the housing 110 through the through hole 1112, enabling the user to intuitively and accurately understand the light signal displayed by the light display component. That is, since the second housing 118 has a through hole 1112 through which the light signal from the light display component passes, there is a possibility that external air may flow into the housing 110 through the through hole 1112. Without a baffle 130, the air flowing into the housing 110 through the through hole 1112 will flow towards the air outlet 112 (such as the second air outlet 1122) via the outer wall of the air inlet structure 140 and the outer wall of the air guide structure 150. There is a possibility that unpurified air will be discharged through the second air outlet 1122. Therefore, in the embodiments provided by this utility model, in the air guide structure 140... A partition 130 is provided between the outer wall of the 50 and the inner wall of the second outer shell 118, so that the air flowing into the outer shell 110 from the through hole 1112 will flow into the first flow channel 113 through the gap at the connection position between the annular mounting bracket 190 and the first outer shell 117, and then be purified by the filter 120 of the first flow channel 113 before being discharged from the first air outlet 1121 through the interior of the air outlet structure 160 and the air guide structure 150. This improves the cleanliness of the air discharged from the air outlet 112, improves the air quality of the external environment, and allows users to breathe fresh air. Specifically, the light display component can be installed on the annular mounting bracket 190, or the light display component can be installed on the outer wall of the air outlet structure 160. It is understood that the light display component can be directly or indirectly installed on the annular mounting bracket 190 through a mounting plate, or the light display component can be directly or indirectly installed on the outer wall of the air outlet structure 160 through a mounting plate.

[0086] In some embodiments, a wiring port is provided on the outer wall of the air inlet structure 140 or the outer wall of the air guide structure 150, so that the connecting wire can extend to the inside and outside of the first flow channel 113 through the wiring port. The connecting wire located inside the first flow channel 113 can be connected to the impeller 170, and the connecting wire located outside the first flow channel 113 can be connected to the electronic control board. Thus, the impeller 170 inside the first flow channel 113 can be electrically connected to the electronic control board outside the first flow channel 113 through the connecting wire. However, the setting of the wiring port makes it possible for air leakage and mixing between the inside and outside of the first flow channel 113. For example, unpurified air outside the first flow channel 113 may flow into the first flow channel 113 through the wiring port and contaminate the purified air inside the first flow channel 113, causing the purified air inside the first flow channel 113 to enter the outside of the first flow channel 113 and reducing the amount of purified air discharged through the air outlet 112. Therefore, a fourth sealing element can be installed at the wire passage to improve the sealing performance at the wire passage, thereby reducing the possibility of air leakage and mixing in the first flow channel 113, reducing the possibility of unpurified air from outside the first flow channel 112 flowing into the first flow channel 113 through the wire passage, reducing the possibility of purified air inside the first flow channel 113 leaking through the wire passage, effectively improving the cleanliness of the air discharged through the air outlet 112, and enabling the air outlet 112 to have a larger air volume, thereby improving the purification effect and purification efficiency of the air handling equipment 100.

[0087] Specifically, the fourth sealing element can be a sealing ring, sealing cotton, sealing adhesive, etc.

[0088] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, an embodiment of the present invention also provides an air handling device 100, including: a housing 110, the housing 110 having an air inlet 111 and an air outlet 112; an air guide assembly disposed inside the housing 110, the air guide assembly and the housing 110 forming a first flow channel 113 and a second flow channel 114 that are connected, the first flow channel 113 connecting the air inlet 111 and the air outlet 112, and the second flow channel 114 connecting the air inlet 111 and the air outlet 112; a filter element 120 disposed in the first flow channel 113, the filter element 120 being configured to filter the air flowing through the first flow channel 113; and a baffle 130 disposed in the second flow channel 114, the baffle 130 being configured to block the air flowing towards the air outlet 112 so that the air flows from the second flow channel 114 to the filter element 120 in the first flow channel 113.

[0089] The air handling device 100 provided in this embodiment of the present invention includes a housing 110, an air guide assembly, a filter element 120, and a baffle element 130. The housing 110 has an air inlet 111 and an air outlet 112. The air guide assembly is located inside the housing 110 and forms a first flow channel 113 and a second flow channel 114 with the housing 110. The first flow channel 113 connects the air inlet 111 and the air outlet 112, so that air can flow to the outside of the housing 110 through the air inlet 111, the first flow channel 113, and the air outlet 112. The second flow channel 114 connects the air inlet 111 and the air outlet 112, so that air can flow to the outside of the housing 110 through the air inlet 111, the second flow channel 114, and the air outlet 112. The first flow channel 113 and the second flow channel 114 are interconnected. In other words, the air flowing into the housing 110 through the air inlet 111 can be discharged through the air outlet 112 via the first flow channel 113 and the second flow channel 114. By installing a filter element 120 in the first flow channel 113, the air flowing through the first flow channel 113 is purified and filtered. This improves the cleanliness of the air flowing to the outside of the housing 110 via the first flow channel 113 and the air outlet 112, thereby improving air quality and allowing users to breathe fresh air. By setting a baffle 130 in the second flow channel 114, the baffle 130 blocks the air flowing from the second flow channel 114 to the air outlet 112. That is, the baffle 130 can isolate the second flow channel 114, so that the air flowing from the second flow channel 114 to the air outlet 112 flows to the filter element 120 in the first flow channel 113. This reduces the possibility that the air in the second flow channel 114 will be discharged from the air outlet 112 without passing through the filter element 120, and increases the possibility that the air discharged from the air outlet 112 will pass through the filter element 120. This improves the cleanliness of the air discharged from the air outlet 112, effectively improves air quality, and enhances the purification effect and efficiency of the air purifier.

[0090] Furthermore, since the baffle 130 is located inside the second flow channel 114, the baffle 130 can achieve the baffle effect of the second flow channel 114 simply by contacting the inner wall of the second flow channel 114. Compared with the baffle 130 being located at the air outlet 112, the contact area between the baffle 130 and the inner wall of the second flow channel 114 can be increased, resulting in a good baffle effect.

[0091] Understandably, the air flowing into the housing 110 through the air inlet 111 can flow through the first flow channel 113 and the second flow channel 114 to the outside of the housing 110 via the air outlet 112. The filter element 120 is located within the first flow channel 113, meaning that a portion of the air flowing into the housing 110 through the air inlet 111 is filtered by the filter element 120 and then discharged through the air outlet 112. This portion of air has high cleanliness due to the purification effect of the filter element 120. Without the baffle 130, a portion of the air flowing into the housing 110 through the air inlet 111 is discharged through the second flow channel 114 via the air outlet 112. This portion of air, having not undergone purification by the filter element 120, remains dirty air and has low cleanliness. If it were directly discharged through the air outlet 112, it would reduce the purification effect of the air purifier. Therefore, in this embodiment of the invention, a baffle 130 is provided in the second flow channel 114 to block the second flow channel 114. That is, the baffle 130 blocks the air flowing from the second flow channel 114 to the air outlet 112, so that the air flowing from the second flow channel 114 to the air outlet 112 flows to the first flow channel 113 and passes through the filter element 120. This part of the air is purified by the filter element 120 of the first flow channel 113 and then discharged from the air outlet 112. Thus, the possibility of the air in the second flow channel 114 being discharged directly from the air outlet 112 without passing through the filter element 120 can be reduced, so that the air discharged from the air outlet 112 is the air that has passed through the filter element 120, thereby improving the cleanliness of the air discharged from the air outlet 112, improving air quality, and improving the purification effect and purification efficiency of the air purifier.

[0092] It is understood that the other structures of the air handling device 100 in this embodiment are the same as the other structures of the aforementioned air handling device 100, and will not be described in detail here.
