Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] The following is for reference. Figures 1-8 This invention describes an air handling device 100 according to an embodiment of the present invention.

[0042] Reference Figure 1 , Figure 2 and Figure 3 An air handling device 100 according to an embodiment of the present invention includes: a housing 1 and an air guide 2. The air guide 2 is disposed inside the housing 1 and is formed in a cylindrical shape. The air handling device 100 has an inner air duct 11 located inside the air guide 2 and an outer air duct 12 located outside the air guide 2.

[0043] Reference Figure 3 , Figure 4 and Figure 5 The housing 1 is provided with an air outlet mesh cover 13, which includes a first air outlet area 131 and a second air outlet area 132. The first air outlet area 131 is correspondingly arranged with the inner air duct 11 to at least discharge part of the airflow in the inner air duct 11, and the second air outlet area 132 is correspondingly arranged with the outer air duct 12 to at least discharge part of the airflow in the outer air duct 12.

[0044] Because the inner air duct 11 and the outer air duct 12 are at least partially spaced apart, the air blown out of the inner air duct 11 is different from the air blown out of the outer air duct 12. For example, in some embodiments, the air velocity in the inner air duct 11 is different from the air velocity in the outer air duct 12; in other embodiments, the degree of rotation of the air in the inner air duct 11 is different from the degree of rotation of the air in the outer air duct 12; in still other embodiments, the temperature of the air in the inner air duct 11 is different from the temperature of the air in the outer air duct 12; in other embodiments, other factors may also cause the air blown out of the inner air duct 11 to be different from the air blown out of the outer air duct 12.

[0045] In this embodiment of the present invention, in order to adapt to the different air blown out by the inner air duct 11 and the outer air duct 12, the air outlet mesh cover 13 is provided with a first air outlet area 131 corresponding to the inner air duct 11 and a second air outlet area 132 corresponding to the outer air duct 12, so that the first air outlet area 131 can better guide the air blown out by the inner air duct 11 and the second air outlet area 132 can better guide the air blown out by the outer air duct 12, thereby improving the overall air outlet effect of the air handling equipment 100.

[0046] It should be noted that the airflow in the inner duct is not limited to the first air outlet area, and the airflow in the outer duct is not limited to the second air outlet area. In some embodiments, the end of the inner duct near the air outlet cover is connected to the end of the outer duct near the air outlet cover, so that part of the airflow in the inner duct can flow to the second air outlet area and then be blown out, and part of the airflow in the outer duct can also flow to the first air outlet area and then be blown out.

[0047] It should be noted that the first air outlet area 131 may include multiple round holes, multiple strip holes, multiple arc holes, or openings of other shapes, as long as air inside the housing 1 can pass through. This invention does not impose any limitations on these shapes. Similarly, the second air outlet area 132 may include multiple round holes, multiple strip holes, arc holes, or openings of other shapes. This invention does not impose any limitations on these shapes.

[0048] According to an embodiment of the present invention, the air handling device 100 is provided with a cylindrical air guide 2. Air ducts for air flow are provided on both the inner and outer sides of the air guide 2, which helps to increase the air volume of the air handling device 100, increase the heat exchange efficiency between the air handling device 100 and the air, and improve the heating effect of the air handling device 100. A first air outlet area 131 is provided corresponding to the inner air duct 11, and a second air outlet area 132 is provided corresponding to the outer air duct 12, so that the first air outlet area 131 can better guide the air blown out of the inner air duct 11, and the second air outlet area 132 can better guide the air blown out of the outer air duct 12, thereby improving the overall air outlet effect of the air handling device 100.

[0049] In some embodiments, the air guide is configured to generate heat.

[0050] Through the above technical solution, the air guide 2 is used to heat the air. In this embodiment of the utility model, the air guide 2 is designed as a cylinder. The cylindrical air guide 2 can not only heat the air, but also guide the air to flow along the axial direction of the air guide 2, effectively reducing the resistance encountered by the air during heat exchange with the air guide 2, which is conducive to increasing the air outlet speed and improving the heating effect. Furthermore, air ducts for air flow are provided on both the inner and outer sides of the air guide 2, which is conducive to increasing the air outlet volume of the air handling equipment 100, increasing the heat exchange efficiency between the air guide 2 and the air, and improving the heating effect of the air handling equipment 100. Among them, the air in the inner air duct 11 can exchange heat with the inner surface of the air guide 2, and the air in the outer air duct 12 can exchange heat with the outer components of the air guide 2.

[0051] In some embodiments, the opening area of ​​the first air outlet region 131 is larger than the opening area of ​​the second air outlet region 132.

[0052] It should be noted that the opening area of ​​the first air outlet area 131 refers to the total area of ​​all through holes in the first air outlet area 131. The opening area of ​​the second air outlet area 132 refers to the total area of ​​all through holes in the second air outlet area 132.

[0053] In this embodiment, the opening area of ​​the first air outlet region 131 is larger than the opening area of ​​the second air outlet region 132, so that the air volume of the first air outlet region 131 can be greater than the air volume of the second air outlet region 132. The first air outlet region 131 is located radially inside the second air outlet region 132, so that the air blown out by the air handling device 100 can be more concentrated radially inside, resulting in the air column blown out by the air handling device 100 being able to blow further, effectively improving the air outlet effect of the air outlet device.

[0054] Reference Figure 3 , Figure 4 and Figure 5 In some further embodiments, the first air outlet region 131 is formed in a ring shape, and the second air outlet region 132 is also formed in a ring shape. The radial distance between the opposite sidewalls of the first air outlet region 131 is a first distance, and the radial distance between the opposite sidewalls of the second air outlet region 132 is a second distance. The second distance is smaller than the first distance.

[0055] In this embodiment of the present invention, the second spacing is smaller than the first spacing, thereby making the opening area of ​​the first air outlet area 131 larger than the opening area of ​​the second air outlet area 132, and the air volume of the first air outlet area 131 can be greater than the air volume of the second air outlet area 132. The first air outlet area 131 is located radially inside the second air outlet area 132, so that the air blown out by the air handling device 100 can be more concentrated on the radially inside, resulting in the air column blown out by the air handling device 100 being able to blow further, effectively improving the air outlet effect of the air outlet device.

[0056] In some specific embodiments, the air outlet cover 13 includes multiple nested fixed rings and multiple air guide ribs. Each air guide rib is connected to two adjacent fixed rings. Multiple air guide ribs are provided between adjacent fixed rings at circumferential intervals. The space between the fixed rings connected by the air guide ribs defines the first air outlet area 131 and the second air outlet area 132.

[0057] In this embodiment of the utility model, the way of defining the first air outlet area 131 and the second air outlet area 132 is simple, which reduces the processing difficulty of the air outlet cover 13 and reduces the cost of the air handling equipment 100.

[0058] Reference Figure 3 , Figure 4 and Figure 5 In some specific embodiments, the air outlet mesh cover 13 includes a first fixing ring 133 located at the center, a second fixing ring 134 outer sleeved on the first fixing ring 133, and a third fixing ring 135 outer sleeved on the second fixing ring 134, wherein the first fixing ring 133, the second fixing ring 134, and the third fixing ring 135 are coaxially arranged. A first air outlet area 131 is defined between the first fixing ring 133 and the second fixing ring 134, and the first air outlet area 131 is defined between the second fixing ring 134 and the third fixing ring 135. Preferably, the third fixing ring 135 is integrally formed with the housing 1.

[0059] The air guide ribs in the first air outlet area 131 are defined as first air guide ribs 136. Multiple first air guide ribs 136 are provided in the first air outlet area 131 at intervals along the circumference. The first end of each first air guide rib 136 is connected to the first fixing ring 133, and the second end of each first air guide rib 136 is connected to the second fixing ring 134, which effectively improves the stability of the connection between the first fixing ring 133, the first air guide ribs 136 and the second fixing ring 134.

[0060] The air guide ribs in the second air outlet area 132 are defined as second air guide ribs 137. Multiple second air guide ribs 137 are provided in the second air outlet area 132 at intervals along the circumference. The first end of each second air guide rib 137 is connected to the second fixing ring 134, and the second end of each second air guide rib 137 is connected to the third fixing ring 135, which effectively improves the stability of the connection between the second fixing ring 134, the second air guide ribs 137 and the third fixing ring 135.

[0061] In some embodiments, the first air guide rib 136 is formed in a curved shape.

[0062] In this embodiment of the invention, by designing the first air guide rib 136 as curved, a curved air duct is formed between two adjacent first air guide ribs 136, which can be adapted to the spiral airflow bundle, making it easier for the spiral airflow bundle to enter the first air outlet area 131, reducing wind resistance. Under the guidance of the first air guide rib 136, the airflow through the first air outlet area 131 converges towards the central axis of the air outlet cover 13, allowing the airflow through the first air outlet area 131 to flow forward more stably and to be transmitted over a longer distance, thus extending the air delivery distance of the air handling equipment 100. Of course, in other embodiments, the first air guide rib 136 can also be other shapes, for example, the first air guide rib 136 can also be a long strip structure extending radially along the air outlet cover 13, and the invention does not limit this.

[0063] In some embodiments, the first air guide rib 136 and the second air guide rib 137 have different shapes.

[0064] Because the inner air duct 11 and the outer air duct 12 are at least partially spaced, the air blown out by the inner air duct 11 is different from the air blown out by the outer air duct 12. In this embodiment of the present invention, the first air guide rib 136 and the second air guide rib 137 have different shapes, resulting in different air guiding effects of the first air outlet area 131 and the second air outlet area 132. This allows the first air outlet area 131 to better guide the air blown out by the inner air duct 11, and the second air outlet area 132 to better guide the air blown out by the outer air duct 12, thereby improving the overall air outlet effect of the air handling equipment 100.

[0065] In some specific embodiments, the first air guide rib 136 is formed in a curved shape, and the second air guide rib 137 is formed in a straight line segment.

[0066] In this embodiment of the invention, when air from the inner air duct 11 and the outer air duct 12 passes through the air outlet cover 13, a portion of the air passes through the first air outlet area 131, and the other portion passes through the second air outlet area 132. The airflow through the first air outlet area 131, guided by the curved first guide ribs 136, converges towards the central axis of the air outlet cover 13, allowing the airflow through the first air outlet area 131 to flow forward more stably and reach a greater distance, thus extending the air delivery distance of the air handling device 100. The airflow through the second air outlet area 132 continues to flow forward in a spiral shape, diffusing radially while moving forward in a spiral motion to form a gentle diffused airflow. In other words, the air handling device 100 not only has the ability to concentrate airflow over a long distance but also to diffuse airflow over a large area.

[0067] Reference Figure 3 , Figure 4 and Figure 5In some other specific embodiments, the first air guide rib 136 is formed in a curved shape, and the second air guide rib 137 is also formed in a curved shape, wherein the degree of curvature of the first air guide rib 136 is less than the degree of curvature of the second air guide rib 137.

[0068] In some application scenarios, because the inner air duct 11 and the outer air duct 12 are partially spaced apart, the degree of rotation of the air in the inner air duct 11 is different from that in the outer air duct 12. The radial velocity of the air in the outer air duct 12 is greater. Therefore, in this embodiment of the present invention, the first air guide rib 136 and the second air guide rib 137 are both designed to convert the radial velocity of the air into the axial velocity. Furthermore, the second air guide rib 137 has a greater degree of curvature, which can better guide the air through the second air outlet area 132 and effectively extend the air delivery distance of the air handling equipment 100.

[0069] In some embodiments, the maximum spacing between two adjacent first air guide ribs 136 is less than 9 mm, which reduces the possibility of external debris passing through, reduces the risk of fingers passing through, and improves the safety of using the air handling equipment 100.

[0070] In some embodiments, the maximum spacing between two adjacent second air guide ribs 137 is less than 9 mm, which reduces the possibility of external debris passing through, reduces the risk of fingers passing through, and improves the safety of using the air handling equipment 100.

[0071] Reference Figure 1 In some embodiments, the housing 1 is further provided with an air inlet screen 14, at least one of the air inlet screen 14 and the air outlet screen 13 being detachably disposed on the housing 1, allowing the user to remove the air inlet screen 14 and / or the air outlet screen 13 for cleaning, and also facilitating the user to clean and maintain the internal structure of the housing 1, thereby improving the ease of use of the air handling equipment 100. In some specific embodiments, the air inlet screen 14 is detachably disposed on the housing 1, and the air outlet screen 13 is integrally formed with the housing 1.

[0072] Reference Figure 1 , Figure 3 and Figure 4 In some embodiments, the air handling device 100 further includes a fan wheel 3, a portion of which extends into the air guide 2, and a portion of which is located outside the air guide 2 to direct air to the outer air duct 12.

[0073] The impeller 3 drives the air outside the housing 1 to enter the housing 1 through the air inlet screen 14, then through the inner air duct 11 and the outer air duct 12, and finally out through the air outlet screen 13. Optionally, the impeller 3 can be a backward centrifugal impeller 3.

[0074] In this embodiment of the invention, a portion of the impeller 3 is located inside the air guide 2. This allows the airflow generated by the impeller 3 during operation to directly enter the inner air duct 11, passing through the interior of the air guide 2. This reduces energy loss, improves the heat exchange between the airflow and the interior of the air guide 2, and provides timely heat dissipation to the interior of the air guide 2. Another portion of the impeller 3 is located outside the air guide 2, directing airflow towards the outer air duct 12. This allows the airflow to pass through the outer air duct 12 during its flow, providing timely heat dissipation to the components on the outside of the air guide 2. Specifically, in practical applications, the inner air duct 11 constructed inside the air guide 2 may be relatively narrow, or the airflow may be affected by other components, resulting in significant airflow resistance. Therefore, placing a portion of the impeller 3 inside the inner air duct 11 facilitates airflow entry into the inner air duct 11, ensuring heat exchange between the airflow and the air guide 2, thereby improving the heat dissipation effect of the impeller 3 on the interior of the air guide 2.

[0075] When the impeller 3 is working, the driving airflow enters the housing 1 from the inlet screen 14 and flows out through the outlet screen 13 via the inner air duct 11 and the outer air duct 12. As the airflow passes through the inner air duct 11, it exchanges heat with the inner surface of the air guide 2. As the airflow passes through the outer air duct 12, it dissipates heat from the outer structure of the air guide 2. This improves the heating effect of the air handling equipment 100, thereby increasing the outlet air temperature and making people feel more comfortable. Furthermore, the airflow passing through the inner air duct 11 dissipates heat from the internal components of the air guide 2, and the airflow passing through the outer air duct 12 dissipates heat from the external components of the air guide 2, thus cooling other components and reducing the temperature impact of the heat generated by the air guide 2 on surrounding components, which helps improve the safety of the air handling equipment 100.

[0076] Reference Figure 1 , Figure 3 and Figure 5 In some embodiments, the air handling equipment 100 also includes a motor 4 connected to the impeller 3. The motor 4, the impeller 3 and the air guide 2 are all located inside the housing 1. The motor 4 is used to drive the impeller 3 to rotate. The impeller 3 drives air to enter from the air inlet and drives the air to flow through the air guide 2 and then blow it out through the air outlet.

[0077] In this embodiment of the utility model, the housing 1 can provide positioning support for the motor 4, impeller 3, and air guide 2, ensuring the overall stability of the air handling equipment 100. Furthermore, since the motor 4, impeller 3, and air guide 2 are all housed within the housing 1, the protection provided by the housing 1 reduces the risk of interference between the motor 4, impeller 3, and air guide 2 and external structures, thereby reducing the risk of damage to the air handling equipment 100 and extending its service life.

[0078] In some embodiments, the air outlet cover 13 is provided with a receiving cavity 1381 for accommodating at least a portion of the motor 4.

[0079] In this embodiment of the invention, the motor 4 is positioned on the exhaust grille 13, that is, on the side of the impeller 3 facing away from the intake grille 14, to prevent the motor 4 from affecting the air intake. Furthermore, at least a portion of the motor 4 is housed within the receiving cavity 1381 of the exhaust grille 13. The protection provided by the exhaust grille 13 reduces the risk of interference between the motor 4 and external structures, lowers the risk of damage to the air handling equipment 100, and extends the service life of the air handling equipment 100.

[0080] In some further embodiments, the air outlet cover 13 is provided with a plurality of spaced through holes 1382, which are connected to the receiving cavity 1381 to dissipate heat from the motor 4, thereby improving the heat dissipation efficiency of the motor 4, reducing the risk of damage to the motor 4, and extending the service life of the air handling equipment 100.

[0081] In some specific embodiments, the air outlet mesh cover 13 further includes a mounting portion 138, which defines a receiving cavity 1381 for accommodating the motor 4. The mounting portion 138 is disposed radially inside the first fixing ring 133. A plurality of reinforcing members 1383 are disposed between the mounting portion 138 and the first fixing ring 133. The plurality of reinforcing members 1383 are distributed circumferentially along the mounting portion 138. The two ends of each reinforcing member 1383 are respectively connected to the mounting portion 138 and the first fixing ring 133, thereby ensuring the stability of the connection between the mounting portion 138 and the first fixing ring 133.

[0082] In some embodiments, the air outlet cover 13 is provided with a guide post 139 passing through the first air outlet area 131 and the second air outlet area 132. The guide post 139 is provided with a guide groove communicating with the receiving cavity 1381, and at least a portion of the wire connected to the motor 4 is located in the guide groove.

[0083] In the above technical solution, the wire is placed in the guide groove to avoid interference between the wire and other structures, thus ensuring the stability of the power supply from the air handling equipment 100 to the motor 4. In addition, the stability of the connection between the mounting part 138, the first fixing ring 133, the second fixing ring 134 and the third fixing ring 135 can be improved by setting the guide column.

[0084] Reference Figure 1 and Figure 3 In some embodiments, blades are formed on the impeller 3. The blades have a first part 31 and a second part 32 arranged sequentially in the axial direction of the impeller 3. The first part 31 is located inside the air guide 2, and the second part 32 is located outside the air guide 2. The diameter of the second part 32 is larger than the diameter of the first part 31.

[0085] It should be noted that the first part 31 and the second part 32 can be directly connected or arranged at intervals. For example, in some embodiments, the first part 31 and the second part 32 are connected sequentially along the axial direction of the impeller 3; in other embodiments, the first part 31 and the second part 32 are arranged at intervals along the circumference of the impeller 3. In this embodiment, the first part 31 and the second part 32 are not directly connected. In other embodiments, other situations are also possible, as long as the first part 31 can be located inside the air guide 2 and guide the airflow to the inner wall of the air guide 2, and the second part 32 can be located outside the air guide 2 and guide the airflow to the outer side of the air guide 2.

[0086] For example, in the axial direction of the impeller 3, the first part 31 of the blade extends into the air guide, and the second part 32 of the blade is located outside the air guide. In the radial direction of the impeller 3, the blade and the air guide are spaced apart to avoid the air guide interfering with the operation of the impeller 3 and to ensure the smooth operation of the impeller 3. At the same time, since one part of the impeller 3 is located inside the air guide and the other part of the impeller 3 is located outside the air guide, it is beneficial to improve the guiding effect of the impeller 3 on the air inside the air guide. It is also convenient for the impeller 3 to drive the air to flow through the two sides of the air guide (i.e., the inner and outer sides of the air guide in the radial direction of the impeller 3). This is beneficial to improve the heat exchange efficiency between the air and the air guide, improve the utilization rate of the heat generated by the air guide, and thus improve the temperature of the hot air output by the air handling equipment 100. It is also beneficial to prevent the local temperature of the air handling equipment 100 from being overheated due to the excessive temperature of the outer surface of the air guide, and improve the safety of the air handling equipment 100.

[0087] Furthermore, in this embodiment of the present invention, the diameter of the second part 32 is larger than the diameter of the first part 31, and the diameter of the part of the impeller 3 located outside the air guide is larger than the diameter of the part of the impeller 3 located inside the air guide, so that the airflow driven by the part of the impeller 3 located outside the air guide can dissipate heat on the components in the outer air duct 12, prevent the components in the outer air duct 12 from overheating, and at the same time help ensure the heat dissipation effect of the impeller 3 on the air guide.

[0088] In some embodiments, the second portion 32 is located on the air inlet side of the air guide 2.

[0089] The impeller 3 is used to drive airflow. When the impeller 3 rotates, it draws air in axially. The air is propelled to rotate by the blades of the impeller 3 within the impeller 3. Under the action of centrifugal force, the air is thrown to the periphery of the impeller 3. In this embodiment of the invention, the second part 32 is located on the air inlet side of the air guide 2, making it easier for the air thrown out by the second part 32 to enter the outer air duct 12, thereby improving the heat dissipation efficiency of the components inside the outer air duct 12.

[0090] In some specific embodiments, the diameter of the second part 32 is larger than the diameter of the air guide 2, so that the second part 32 can more easily guide air to the outer air duct 12, thereby improving the heat dissipation efficiency of the components inside the outer air duct 12.

[0091] In some embodiments of this utility model, in the axial direction of the impeller 3, the diameter of the second part 32 of the blade is D, and the diameter of the first part 31 of the blade is d, where 0.5≤d / D≤0.9.

[0092] When d / D < 0.5, it is easy to cause poor heat dissipation effect of the impeller 3 on the air guide, or to cause the diameter of the part of the impeller 3 located outside the air guide to be too large, thereby increasing the size of the air handling equipment 100; when d / D > 0.9, it is easy to cause poor heat dissipation effect of the impeller 3 on the components inside the outer air duct 12, or to cause the diameter of the part of the impeller 3 located inside the air guide to be too large, thereby causing the gap between the impeller 3 and the air guide to be too small, thus affecting the air outlet effect of the impeller 3.

[0093] Reference Figure 1 , Figure 3 and Figure 4 In some embodiments, the air handling device 100 further includes a coil module 5, which includes an electromagnetic coil for generating a magnetic field. The air guide 2 is configured to heat up under the influence of the magnetic field of the electromagnetic coil. The coil module 5 is located outside the air guide 2, and the coil module 5 and the housing 1 define an outer air duct 12.

[0094] The air guide 2 can be a conductor or conductive body with free charges that can be driven to heat up by the magnetic field generated by the electromagnetic coil. For example, the air guide 2 can be iron with magnetic material, or it can be aluminum with non-magnetic material.

[0095] In this embodiment of the invention, electromagnetic induction heating can be achieved through the cooperation of the electromagnetic coil and the air guide 2. This heating method has advantages such as uniform heating and rapid response, which helps to improve the heating efficiency of the air handling equipment 100 and facilitates the control of the heating temperature. Furthermore, the air guide 2 is configured to generate heat under the magnetic field of the electromagnetic coil, improving thermal efficiency and reducing energy loss. This ensures that air is heated when flowing through the air guide 2, and the heated air can change its flow direction under the action of the air guide 2, ultimately achieving the effect of a large volume of hot air output. In addition, this embodiment of the invention can also dissipate heat from the coil module 5 through the outer air duct 12, improving the heating effect of the air handling equipment 100, increasing the heat dissipation efficiency of the coil module 5, and extending the service life of the air handling equipment 100.

[0096] In some specific embodiments, the coil module 5 includes a coil support 51 and an electromagnetic coil. An outer air duct 12 is defined between the outer peripheral wall of the coil support 51 and the inner peripheral wall of the housing 1. The electromagnetic coil is located on the outer peripheral wall of the coil support 51.

[0097] The coil bracket 51 is correspondingly set with the air guide and is located on the outside of the air guide in the radial direction of the impeller 3. This helps to ensure the effective cooperation between the electromagnetic coil and the air guide. When the electromagnetic coil is energized, it can generate a magnetic field, which can make the air guide heat up, thereby providing an efficient way to heat the air. In addition, the coil bracket 51 can provide stable support for the electromagnetic coil, which helps to improve the assembly stability of the electromagnetic coil.

[0098] Furthermore, in this embodiment of the invention, an outer air duct 12 is defined between the outer peripheral wall of the coil support 51 and the inner peripheral wall of the housing 1. The electromagnetic coil can be cooled through the outer air duct 12, thereby extending the service life of the air handling equipment 100.

[0099] In some specific embodiments, the coil support 51 is formed in a cylindrical shape, the coil support 51 is sleeved on the air guide, and a plurality of winding protrusions 511 are provided on the outer peripheral wall of the coil support 51. The plurality of winding protrusions 511 are arranged at intervals in the axial direction of the coil, and a winding groove for placing the electromagnetic coil is formed between two adjacent winding protrusions 511. The electromagnetic coil can be set on the coil support 51 through the plurality of winding grooves to improve the assembly stability of the electromagnetic coil.

[0100] In some further embodiments, the coil support 51 is sleeved on the air guide 2 and spaced apart from the air guide 2, so that air can pass through the gap between the coil support 51 and the air guide 2 to exchange heat on the outer surface of the air guide 2, which effectively improves the heating effect of the air handling equipment 100 on the air and improves the heating effect of the air handling equipment 100.

[0101] In other words, in this embodiment of the utility model, the air entering the housing 1 through the air inlet mesh cover 14 will be divided into three parts. The first part of the air flows to the first air outlet area 131 through the inner air duct 11 inside the air guide 2. The second part of the air flows to the first air outlet area 131 through the gap between the coil bracket 51 and the air guide 2. The third part of the air flows to the second air outlet area 132 through the outer air duct 12 between the coil bracket 51 and the housing 1.

[0102] Reference Figure 4 , Figure 5 and Figure 6In some embodiments, on a cross section parallel to the axial direction of the impeller 3, the distance between the air outlet end of the coil bracket 51 and the air outlet end of the air guide 2 is S1, the maximum diameter of the air outlet end of the air guide 2 is Df, the maximum diameter of the air outlet end of the coil bracket 51 is Di, and the air handling equipment 100 satisfies: Di=Df+2*S1.

[0103] In other words, the air guide 2 and the coil bracket 51 are coaxially arranged, which allows the air guide 2 to be evenly distributed around its periphery, improving the uniformity of the air output of the air handling equipment 100 and enhancing the comfort of using the air handling equipment 100.

[0104] In some embodiments, the air handling unit 100 satisfies: 1.1 ≤ Di / Df ≤ 1.2.

[0105] If Di / Df is less than 1.1, the distance S1 between the air outlet of the coil bracket 51 and the air outlet of the air guide 2 will be too small, resulting in less airflow between the coil bracket 51 and the air guide 2, poor heat dissipation efficiency of the coil bracket 51 and the air guide 2, and affecting the heating efficiency of the air. If Di / Df is greater than 1.2, the distance S1 between the air outlet of the coil bracket 51 and the air outlet of the air guide 2 will be too large, which is not conducive to the miniaturization of the air handling equipment 100 as a whole.

[0106] In this embodiment, the air handling device 100 satisfies: 1.1≤Di / Df≤1.2, which not only allows sufficient airflow between the coil support 51 and the air guide 2 to improve the heating effect of the air handling device 100 on the air, but also limits the size of the coil support 51, which is beneficial to the miniaturization of the air handling device 100.

[0107] In some specific embodiments, Di / Df is any one of the point values ​​of 1.1, 1.13, 1.14, 1.18, and 1.2, or a range of values ​​between any two.

[0108] In some specific embodiments, the diameter of the second fixing ring 134 is equal to the maximum diameter of the air outlet end of the coil bracket 51, so that the airflow in the outer air duct can pass through the second air outlet area.

[0109] In some embodiments, on a cross section parallel to the axial direction of the impeller 3, the maximum diameter of the air outlet end of the coil support 51 is Di, the distance between the air outlet end of the inner peripheral wall of the housing 1 and the air outlet end of the coil support 51 is S2, the diameter of the air outlet end of the inner peripheral wall of the housing 1 is Do, and the air handling equipment 100 satisfies: Do=Di+2*S2.

[0110] In other words, the housing 1 and the coil support 51 are coaxially arranged, which allows the coil support 51 to discharge air evenly around its periphery, improving the uniformity of the air discharge from the air handling equipment 100 and enhancing the comfort of using the air handling equipment 100.

[0111] In some embodiments, the air handling unit 100 satisfies: 1.1 ≤ Do / Di ≤ 1.4.

[0112] If Do / Di is less than 1.1, the distance S2 between the air outlet end of the inner peripheral wall of the housing 1 and the air outlet end of the coil support 51 will be too small, resulting in less airflow between the housing 1 and the coil support 51, poor heat dissipation efficiency of the coil support 51, and affecting the heating efficiency of the air. If Do / Di is greater than 1.4, the distance S2 between the air outlet end of the inner peripheral wall of the housing 1 and the air outlet end of the coil support 51 will be too large, which is not conducive to the miniaturization of the air handling equipment 100 as a whole.

[0113] In this embodiment, the air handling device 100 satisfies: 1.1≤Do / Di≤1.4, which not only allows sufficient airflow between the housing 1 and the coil support 51 to improve the heating effect of the air handling device 100 on the air, but also limits the size of the housing 1, which is beneficial to the miniaturization of the air handling device 100.

[0114] In some specific embodiments, Do / Di is any one of the point values ​​of 1.1, 1.15, 1.2, 1.3, and 1.4, or a range of values ​​between any two.

[0115] In some embodiments, the distance S2 between the air outlet end of the inner peripheral wall of the housing 1 and the air outlet end of the coil bracket 51 ranges from 10mm to 40mm.

[0116] If S2 is less than 10mm, the airflow in the outer duct 12 will be too small, affecting the heat dissipation efficiency of the electromagnetic coil. If S2 is greater than 40mm, the overall volume of the air handling unit 100 will be too large, which is not conducive to the use of the air handling unit 100.

[0117] In this embodiment of the utility model, the range of the distance S2 between the air outlet end of the inner peripheral wall of the housing 1 and the air outlet end of the coil support 51 is further defined. While ensuring the heat dissipation efficiency of the electromagnetic coil, the overall volume of the air handling equipment 100 is also limited, thereby improving the applicability of the air handling equipment 100.

[0118] In some specific embodiments, the distance S2 between the air outlet end of the inner peripheral wall of the housing 1 and the air outlet end of the coil bracket 51 can be a point value of any one of 10mm, 20mm, 25mm, 30mm, and 40mm or a range value between any two.

[0119] Reference Figure 1 , Figure 3 and Figure 7 In some embodiments, the air handling equipment 100 further includes a magnetic shielding component 6, which is disposed between the coil module 5 and the housing 1, and the magnetic shielding component 6 is made of magnetic material.

[0120] Considering that after the electromagnetic coil is energized, a magnetic field will also be generated on the side of the electromagnetic coil away from the air guide in the radial direction of the impeller 3, causing magnetic field leakage, by setting a magnetic shielding component 6 on the side of the electromagnetic coil away from the air guide, the amount of magnetic field leakage on the side of the electromagnetic coil away from the air guide can be reduced, which is beneficial to improving the energy utilization rate in the air handling equipment 100.

[0121] Reference Figure 1 and Figure 3 In some embodiments, the magnetic shielding element 6 includes a plurality of magnetic strips spaced circumferentially along the electromagnetic coil.

[0122] By arranging multiple magnetic strips at intervals along the circumferential direction of the electromagnetic coil, the magnetic shielding component 6 is able to effectively shield the electromagnetic coil from magnetic field leakage on the side away from the air guide component. This increases the magnetic field strength on the side of the electromagnetic coil closer to the air guide component, thereby improving the heating effect of the air guide component and ultimately enhancing the heating efficiency of the air handling equipment 100.

[0123] In some specific embodiments, the material of the magnetic strip can be selected from one or more of neodymium iron boron permanent magnet materials, ferrite permanent magnet materials, silicon steel materials, metal soft magnetic powder core materials, and ferrite soft magnetic materials.

[0124] In some embodiments of this utility model, the air handling equipment 100 further includes a magnetic strip support 62, which is formed in a ring shape and is sleeved on the radial outer side of the electromagnetic coil in the radial direction of the impeller 3. The magnetic strip support is used to install magnetic strips. By setting the magnetic strip support 62, it is convenient to assemble the magnetic shielding component 6 and at the same time, it is beneficial to improve the assembly reliability of the magnetic shielding component 6.

[0125] Reference Figure 7 In some embodiments, the magnetic shielding element 6 is configured to heat up under the action of a magnetic field. The magnetic shielding element 6 is formed in a cylindrical shape. When the electromagnetic coil is energized, it can generate a magnetic field, so that the air guide 2 can achieve electromagnetic induction heating. The magnetic shielding element 6 can also achieve electromagnetic induction heating. The magnetic shielding element 6 improves the heating effect of the air in the outer air duct 12, and further improves the heating effect of the air handling equipment 100.

[0126] In some further embodiments, the magnetic shielding component 6 and the coil module 5 are spaced apart, allowing air in the outer air duct to pass through the gap between the magnetic shielding component 6 and the coil module 5, thereby improving the heat dissipation effect of the magnetic shielding component 6 and improving the heating effect of the air handling equipment.

[0127] In some embodiments, the air handling device 100 is configured to have a cold air mode and a warm air mode. In the warm air mode, the air guide 2 works to generate heat to heat the air, and the impeller 3 works to drive the air flow, thereby blowing out warm air. In the cold air mode, the air guide 2 does not work, and the air flow is driven only by the impeller 3.

[0128] With the above technical solution, when the outside temperature is low, the air handling unit 100 can be used for heating in the warm air mode, and when the outside temperature is high, the air handling unit 100 can be used for cooling in the cold air mode, which effectively increases the applicability of the air handling unit 100.

[0129] In some embodiments of this utility model, the air handling device 100 has a cold air mode and a warm air mode. The control method further includes determining the operating mode of the air handling device 100, thereby setting the air handling device 100 to operate in either a cold air mode or a warm air mode according to the user's selection, ensuring that the air handling device 100 can provide suitable air output according to the user's usage needs, which is beneficial to improving the functionality of the air handling device 100.

[0130] Based on this, the operating mode of the air handling equipment 100 can be controlled by controlling the operating status of the impeller 3 and the air guide 2. When the air handling equipment 100 is in the cold air mode, the impeller 3 can be started to generate cold air, while the air guide 2 does not generate heat, so as to ensure that the air handling equipment 100 can provide pure cold air, so that the air handling equipment 100 can be used to cool down environments with high temperatures, and at the same time, it helps to reduce the energy consumption of the air handling equipment 100.

[0131] It should be noted that when the air handling unit 100 is started and selected to operate in cold air mode, there is no action to stop the air guide 2 from generating heat. However, if the air handling unit 100 switches from warm air mode to cold air mode, there is an action to stop the air guide 2 from generating heat.

[0132] When the air handling unit 100 is in warm air mode, the impeller 3 and the air guide 2 work simultaneously to ensure that the air handling unit 100 can output hot air, so that the air handling unit 100 can be used to heat low-temperature environments.

[0133] In some embodiments, the cooling mode of the air handling unit 100 needs to ensure that the air speed output by the air handling unit 100 is sufficiently high. That is, the cooling mode of the air handling unit 100 has more speed settings than the heating mode, and the maximum air speed in the cooling mode is greater than the maximum air speed in the heating mode. For example, the cooling mode of the air handling unit 100 can have 8 speed settings, and the heating mode can have 3 speed settings. When the air handling unit 100 switches directly from the 3rd speed setting in the cooling mode to the heating mode, the air handling unit 100 operates at the maximum speed setting (i.e., the third speed setting) in the heating mode, and the efficiency of the air handling unit 100 in outputting hot air is the highest.

[0134] The following describes two assembly methods of the air handling equipment 100 based on the structure of the air handling equipment 100 according to an embodiment of the present invention.

[0135] Reference Figure 1 and Figure 3 Assembly Method 1: The electromagnetic coil is installed on the coil bracket 51, and the air guide 2 is fixedly connected to the coil bracket 51. The magnetic shielding component 6 is installed on the magnetic strip bracket 62. The magnetic strip bracket 62 is sleeved on the radial outer side of the coil bracket 51 and fixedly connected to the coil bracket 51. The impeller 3 can be positioned in the center area of ​​the air guide 2 by hand, thereby realizing the modular assembly of the air guide 2, coil module 5, magnetic shielding component 6 and impeller 3. Then, the above components are put into the housing through the air inlet of the housing, and the coil bracket 51 and impeller 3 are further connected to the housing respectively. Finally, the air inlet screen 14 is installed at the air inlet of the housing to complete the assembly of the air handling equipment 100.

[0136] In order to ensure the reliability of the assembly between the internal components and the outer shell, the magnetic strip bracket 62 can be further connected to the outer shell to reduce the risk of the internal components falling off the outer shell.

[0137] Assembly Method 2: First, the air guide 2 is fixedly installed inside the outer casing. Then, the coil bracket 51 with the electromagnetic coil is fitted on the radial outer side of the heating element, and the coil bracket 51 is fixedly connected to the outer casing. Next, the magnetic strip bracket 62 is fitted on the radial outer side of the coil bracket 51 and fixedly connected to the outer casing. Then, the impeller 3 is positioned and installed in the central area of ​​the air guide 2. Finally, the air inlet screen 14 is installed at the air inlet of the outer casing to complete the assembly of the air handling equipment 100.

[0138] It should be noted that the above-mentioned fixed connection methods can all use threaded connectors to fix the components together, so as to facilitate the disassembly, maintenance and cleaning of the machine head. Of course, it is understood that the fixed connection methods include but are not limited to connecting with threaded connectors, and can also be snap-fit, etc. The specific fixed connection method can be determined according to the actual production requirements, and no specific limitation is made here.

[0139] The heater 200 according to an embodiment of the present invention includes the air handling equipment 100 described above.

[0140] According to the embodiment of this utility model, the heater 200 is provided with a cylindrical air guide 2. The cylindrical air guide 2 can not only heat the air, but also guide the air to flow along the axial direction of the air guide 2, effectively reducing the resistance encountered by the air during heat exchange with the air guide 2, which is conducive to increasing the air outlet speed and improving the heating effect. In addition, air ducts for air flow are provided on both the inner and outer sides of the air guide 2, which is conducive to increasing the air outlet volume of the air handling equipment 100, increasing the heat exchange efficiency between the air guide 2 and the air, and improving the heating effect. The heating effect of the heater 200 is improved by providing a first air outlet area 131 corresponding to the inner air duct 11 and a second air outlet area 132 corresponding to the outer air duct 12. The opening area of ​​the first air outlet area 131 is larger than that of the second air outlet area 132, which allows the air volume of the first air outlet area 131 to be greater than that of the second air outlet area 132. This allows the air column blown out by the heater 200 to travel further, effectively improving the air outlet effect of the heater 200.

[0141] like Figure 8 As shown, in some embodiments of this utility model, the heater 200 further includes a mounting bracket 210, and the air handling unit 100 is rotatably mounted on the mounting bracket 210 to adjust the air outlet direction.

[0142] The mounting bracket 210 serves as the mounting carrier for the air handling unit 100, supporting the air handling unit 100. The air handling unit 100 can rotate relative to the mounting bracket 210, allowing it to oscillate left and right and / or up and down relative to the mounting bracket 210. This adjusts the air outlet direction of the heater 200, improving its heating effect and uniformity, and enhancing the user experience.

[0143] The air handling unit 100 can be driven to rotate relative to the mounting bracket 210 by a drive structure, which can be configured as a motor.

[0144] Combination Figure 8According to the embodiment of the present utility model, the heater 200 also includes a base 220 and a drive unit. The mounting bracket 210 is rotatably connected to the base 220. The drive unit is disposed on the base 220 and is used to drive the mounting bracket 210 to swing in the left and right direction. The mounting bracket 210 constructs an installation space, and the inner wall of the installation space is provided with a connecting part. The air handling device 100 is rotatably connected to the connecting part and accommodated in the installation space. For example, the connecting part of the mounting bracket 210 clamps the air handling device 100 in the left and right direction and drives the air handling device 100 to swing up and down.

[0145] Optionally, the vertical swing of the air handling unit 100 can also be in the form of a guide rail. Alternatively, the mounting bracket 210 can be mounted on the base 220, and the drive unit can be mounted on the mounting bracket 210 and connected to the air handling unit 100 to drive the air handling unit 100 to swing vertically or horizontally.
