Description

Technical Field

[0001] This invention relates to the field of air handling equipment technology, and more specifically to an air handling equipment with an improved main structure and its main structure. Background Technology

[0002] Existing air handling equipment includes a main structure, filter components, and a disinfection module. The main structure includes a base, an air supply device, a housing, and an air outlet component. The air supply device includes a metal volute duct, dual-inlet centrifugal fan blades, and a motor. For ease of installation of the air supply device and filter components, the housing is a component mainly composed of four housing parts. The air supply device is mounted on the base, located in the center with the duct outlet facing upwards. The four housing parts are positioned around the base and interlocked. Two of these housing parts are located directly opposite the two duct inlets on the volute duct, and the filter components are mounted on these two housing parts. The flared air outlet component is positioned above the volute duct and supported on the housing, connecting to the duct outlet of the volute duct.

[0003] Although this type of air handling equipment has the advantage of good airflow, the airtightness of the multi-component shell is poor, which makes it difficult to eliminate motor noise, and the assembly is difficult. In addition, the protection function and component installation function are combined into the shell, which makes the shell volume ratio large, and it requires the use of high strength and heavy materials, which is not conducive to product lightweighting. Summary of the Invention

[0004] The primary objective of this invention is to provide a main structure for an air handling device that incorporates a mounting body between the outer casing and the air supply device. This invention improves the assembly method of the device, solves noise problems, and reduces product weight.

[0005] A second objective of the present invention is to provide an air handling device in which an installation body is added between the outer casing and the air supply device.

[0006] The main structure of the air handling equipment provided by the first objective of the present invention includes a shell and an air supply device. The air supply device includes a duct shell, and a front air duct is formed inside the duct shell. It also includes an installation body disposed inside the shell. The installation body includes two splicing parts that are spliced ​​together. The installation body forms a device mounting position and a rear air duct between the two splicing parts. The duct shell is disposed at the device mounting position, and the front air duct and the rear air duct are connected.

[0007] As can be seen from the above solution, compared with the prior art, the present invention adds a mounting body between the air supply device and the outer casing. Thus, the mounting function originally required on the outer casing is transferred to the mounting body, allowing the outer casing to be designed in a thinner and more integrated form. During the assembly of the air handling equipment, two splicing pieces are joined from both sides to wrap around the air supply device, and then the outer casing is fitted. Other components can be pre-installed on the splicing pieces or installed after the splicing pieces are assembled into the mounting body. It is evident that the air handling equipment of the present invention has a simpler assembly method, which helps to reduce production difficulty and improve production efficiency. Furthermore, both the mounting body and the outer casing can more tightly cover the outside of the air supply device. The mounting body can be molded from a lighter material with better vibration damping and sound insulation effects, thus effectively solving the noise problem and achieving weight reduction. In addition, some existing air handling equipment eliminates the duct housing and forms the duct by splicing together lightweight splicing parts, with the motor and fan blades directly fixed to the lightweight splicing parts; however, in this invention, after adding the installation body, the duct housing is retained and the air outlet duct is formed by combining the duct housing with the installation body. This method can better guarantee the air volume and air delivery distance.

[0008] A further option is to join the two splicing components radially along the rotation axis of the air supply device; or to join the two splicing components radially along the rotation axis of the air supply device, and to join the two splicing components horizontally.

[0009] As can be seen from the above, generally speaking, whether it is a spliced ​​metal volute or a spliced ​​lightweight air duct component, due to the need for internal fit with the fan blades and the ease of molding, the splicing is usually carried out along the axial direction of the fan blades, which is the axial direction of the rotation axis of the air supply device. However, in practice, when the mounting body added to the outside of the air supply device is set as a spliced ​​structure, it is more beneficial to reduce the product size by splicing the two splicing parts radially along the rotation axis of the fan blades, or better yet, by splicing them along the aforementioned radial direction and horizontally.

[0010] A further proposed solution is that the main installation body includes an air inlet formed between two splicing parts; the duct housing has a first duct inlet; and the air inlet is connected to the first duct inlet.

[0011] A further proposed solution is that the main installation unit includes a filter module mounting position, which is formed between two splicing parts; the filter module mounting position is located between the air inlet and the first air duct inlet.

[0012] As can be seen from the above, setting the filter module mounting position on the main body requires consideration of the molding difficulty of the main body. However, since the two splicing parts are joined radially, the features of the axially connected air inlet and the filter module mounting position can be divided into the two splicing parts to facilitate the molding of the splicing parts.

[0013] A further improvement is that the splicing components are equipped with insertion ports, which are used for the filter modules placed in the filter module mounting positions to enter and exit.

[0014] As can be seen from the above, the insertion port allows for the removal and installation of the filter module, making it convenient for users to replace it regularly.

[0015] A further option is that, axially along the rotation axis of the air supply device, the size of the mounting body is a first dimension; horizontally and radially, the size of the mounting body is a second dimension; the second dimension is smaller than the first dimension.

[0016] As can be seen from the above, the arrangement of splicing two components radially can effectively reduce the radial size of the equipment, thus making the radial size smaller than the axial size, further achieving product miniaturization and improving air delivery efficiency.

[0017] The second objective of this invention is to provide an air handling device comprising a main structure and an air handling module; the main structure adopts the aforementioned main structure; the main structure includes at least one of the following: the air handling module includes a filter module, at least one filter module acting at the air inlet of the air handling device, and / or, at least another filter module acting at the air outlet of the air handling device; the air handling module includes a disinfection module, at least one disinfection module acting at the air inlet of the air handling device, and / or, at least another disinfection module acting at the air outlet of the air handling device.

[0018] A further option is to include an air guide; the rear air duct has a second air duct outlet, the air guide is fixedly installed opposite the second air duct outlet, and an air outlet is formed between the air guide and the installation body; a reversing air duct is formed between the air outlet and the second air duct outlet.

[0019] As can be seen above, after the airflow is sent out from the rear air duct, it will reach the reversing air duct and change direction under the guidance of the air guide surface, thereby changing the blowing direction.

[0020] A further embodiment is that the air guide includes a first air guide section and a second air guide section, which are sequentially arranged between the outlet of the second air duct and the air outlet; the air handling equipment includes at least one of the following: the first air guide section includes a spherical crown surface; the second air guide section includes the side surface of a frustum; the reversing air duct surrounds the outer periphery of the air guide, and the air outlet is annular.

[0021] As can be seen above, after the airflow is sent out from the rear air duct, part of it will first contact the first air guide and then the second air guide, while the other part will directly contact the second air guide. The spherical crown surface of the first air guide can smoothly guide the airflow and diffuse it to its outer periphery, and then be further guided by the diffused second air guide. This setting can effectively change the air delivery direction while ensuring the flow rate and flow volume, so that the airflow is evenly sent out from the outer periphery of the equipment in all directions.

[0022] A further solution includes an air outlet grille, which is located at the air outlet; the air outlet grille has curved guide vanes, and the curvature of the guide vanes is consistent with the reversing trend of the reversing air duct.

[0023] As can be seen from the above, the air outlet grille further guides the airflow and also provides shielding and protection.

[0024] A further option is to include a base, with the air supply device fixedly connected to the base, and the base supporting the mounting body; and / or, to include a housing, which surrounds the mounting body and restricts the splicing of the splicing components from the splicing direction of the splicing components.

[0025] As can be seen from the above, the air supply device, which is the center of gravity of the equipment, is first fixed to the base, then the main body is assembled and installed outside the air supply device, and finally the outer shell is installed. The base, air supply device, main body and outer shell are mutually constrained, and the assembly method is simple and the structure is compact.

[0026] A further option includes at least one of the following: the duct housing is a volute; the duct housing has two opposing first duct inlets; the air inlet direction and the air outlet direction of the duct housing are perpendicular to each other.

[0027] Further options include: the unit weight of the splicing components is less than the unit weight of the duct shell; or, the splicing components are made of foam material; or, the splicing components are made of foam material and the duct shell is made of metal material.

[0041] First embodiment of air handling equipment

[0042] See Figures 1 to 8 This embodiment is a portable air sterilizer. For ease of explanation, the same spatial rectangular coordinate system is established in all the accompanying drawings. In the coordinate system, the x-axis and y-axis are both horizontal, the z-axis is vertical, the x-axis is the width of the air sterilizer, the y-axis is the length of the air sterilizer, and the z-axis is the height of the air sterilizer.

[0043] See Figure 1 and Figure 2 The air purifier has a roughly rectangular outer profile and two air inlets 21 located on opposite sides along the y-axis, with an air outlet 25 located at its top. It also includes a surrounding outer casing 1, consisting of four side walls extending from end to end around the outer perimeter of the air purifier. A door 12 is located on one side wall along the x-axis, allowing the filter module inside the air purifier to be removed and replaced by opening the door 12. Furthermore, the outer casing 1 has mesh-like air inlet vents at both the air inlets 21 and the air outlet 25. Finally, the air purifier has four casters 49 with brakes at its bottom.

[0044] See Figures 1 to 4 The air sterilizer includes a base 4, an air supply device 3, a mounting body 2, a housing 1, casters 49, a filter module, and a sterilization module 19. The base 4, air supply device 3, mounting body 2, and housing 1 constitute the main structure of the invention. The base 4 is a rectangular platform with four casters 49 mounted at the four corners of its lower side. The volute 31 of the air supply device 3 is securely mounted on the base 4 by two legs 48, with the air supply device 3 located at the center above the base 4. The legs 48 reduce the contact area between the air supply device 3 and the base 4, and the legs 48 have a certain degree of recoverable deformation capability, providing a certain degree of vibration damping. This design effectively reduces resonance noise generated during motor operation.

[0045] The mounting body 2 in this embodiment mainly includes a first splicing component 5 and a second splicing component 6. Both the first splicing component 5 and the second splicing component 6 are splicing components of the present invention. After the first splicing component 5 and the second splicing component 6 are connected along the x-axis, they can externally shield and protect the air supply device 3. The mounting body 2 is also supported by the base 4. The filter module and the disinfection module 19 are both installed on the mounting body 2. The outer shell 1 can be fitted onto the mounting body 2 from top to bottom, providing shielding and protection from the outer periphery and top of the mounting body 2, and also restricting the mounting body 2 from the splicing direction.

[0046] Combined Figure 5 First, in this embodiment, the volute 31 of the air supply device 3 is the air duct housing of the present invention. The air supply device 3 also includes a motor (not shown in the figure) installed inside the volute 31. Figure 5 The centrifugal fan blade 39 is shown. The volute 31 is made of metal and includes a volute air duct 310 formed within itself. The volute air duct 310 serves as the front air duct of this invention. First air duct inlets 311 of the volute air duct 310 are provided on opposite sides of the lower part of the volute 31 in the y-axis direction, and an upward-facing first air duct outlet 312 of the volute air duct 310 is provided on the top of the volute 31. The motor is fixed inside the volute 31 by a cross-shaped mounting bracket 393, and the extension direction of the motor's output shaft is the y-axis direction. The centrifugal fan blade 39 is fixedly connected to the motor's output shaft. The extension direction of the rotation axis of the centrifugal fan blade 39 is the y-axis direction, meaning the axial direction of the rotation axis of the air supply device is the y-axis direction. The centrifugal fan blade 39 includes a first blade group 391 and a second blade group 392 arranged opposite each other in the y-axis direction. When the centrifugal fan blade 39 rotates, it can achieve bidirectional air intake in both the positive and negative y-axis directions and centrifugal air exhaust. Figure 5It can be seen that multiple blades in the first blade group 391 and multiple blades in the second blade group 392 are staggered, which is intended to reduce noise. When the centrifugal fan blade 39 rotates, both the first blade group 391 and the second blade group 392 will generate corresponding noise signals. The staggered distribution of the first blade group 391 and the second blade group 392 can make one noise signal 180 degrees out of phase with the other noise signal, thus becoming its inverse signal. The inverse signal is superimposed on the original signal to cancel out the noise generated by the original signal.

[0047] See Figure 4 , Figures 6 to 8 Both the first splicing component 5 and the second splicing component 6 are made of EPP foam material. Both the first splicing component 5 and the second splicing component 6 are semi-integral structures. Multiple features such as the air inlet 21, filter module mounting position 22, device mounting position 23, rear air duct 24 and air outlet 25 on the main body 2 are formed after the first splicing component 5 and the second splicing component 6 are spliced ​​together.

[0048] The first splicing component 5 forms two first air inlet halves 51, two first filter module mounting halves 52, and a first device mounting half 53 located at its lower part. The first splicing component 5 also forms a first rear air duct half 54 located at its upper part. In the y-axis direction, the first device mounting half 53 is located in the center position. The two first filter module mounting halves 52 are respectively arranged on opposite sides of the first device mounting half 53, adjacent to and connected to the first device mounting half 53. The two first air inlet halves 51 are respectively arranged on opposite sides of the first device mounting half 53 and are located at a position farther away from the first device mounting half 53 than the first filter module mounting half 52. The two first air inlet halves 51 are respectively adjacent to and connected to the two first filter module mounting halves 52.

[0049] Furthermore, the first splicing component 5 has a first slot group 521 on both sides of the z-axis direction, i.e., the upper and lower sides, facing the first filter module mounting half 52. The filter module in this embodiment includes a HEPA filter and an activated carbon filter. The first slot group 521 includes two slots respectively corresponding to the HEPA filter and the activated carbon filter. Both slots are arranged along the x-axis direction.

[0050] The first splicing component 5, while forming the recessed half, also forms several protruding structures, including a first upper limit boss 522, a first lower limit boss 523, and a second lower limit boss 532. In the x-axis direction, the first upper limit boss 522 and the first lower limit boss 523 protrude from the upper and lower sides of the first filter module mounting half 52, respectively. The first slot group 521 is disposed on the first upper limit boss 522 and the first lower limit boss 523. In the z-axis direction, the second lower limit boss 532 protrudes below the first device mounting half 53, and the second lower limit boss 532 has an arc surface facing the first device mounting half 53. Additionally, the first splicing component 5 is provided with a first window 530, and the first device mounting half 53, the first window 530, and the outside are sequentially connected along the negative x-axis.

[0051] The first rear air duct half 54 is positioned above the first device mounting half 53, and the first device mounting half 53 and the first rear air duct half 54 are connected along the positive z-axis. Along the positive z-axis, the dimensions of the first rear air duct half 54 gradually increase in both the y-axis and x-axis directions, with a greater increase in the y-axis direction. A first module mounting position 541 is provided on the inner wall surface at the upper end of the first rear air duct half 54, and the disinfection module 19 is installed in the first module mounting position 541. In this embodiment, the disinfection module 19 is a plasma generator, and the emitter head of the disinfection module 19 is located within the first module mounting position 541 or slightly protrudes from the inner wall surface at the upper end of the first rear air duct half 54. With this configuration, the charge emitted by the disinfection module 19 can be released into the air duct, and the emitter head of the disinfection module 19 is not affected by factors such as humidity and temperature in the air duct, ensuring its service life.

[0052] Additionally, on the first splicing component 5, the end face of the aforementioned protrusion structure facing the positive x-axis is provided with a central insertion port 501, a lower insertion port 502, and an upper insertion port 503. The central insertion port 501, lower insertion port 502, and upper insertion port 503 are located in the middle, lower, and upper parts of the z-axis direction, respectively. The central insertion port 501 is provided on the aforementioned first limiting boss 531. The inner contours of the central insertion port 501 and the lower insertion port 502 are roughly "I"-shaped, while the inner contour of the upper insertion port 503 is straight. The central insertion port 501 has the largest size, followed by the lower insertion port 502, and the central insertion port 501 has the smallest size.

[0053] The second splicing component 6 forms two second air inlet halves 61, two second filter module mounting halves 62, and a second device mounting half 63 located at its lower part. The second splicing component 6 also forms a second rear air duct half 64 located at its upper part. In the y-axis direction, the second device mounting half 63 is located in the center position. The two second filter module mounting halves 62 are respectively arranged on opposite sides of the second device mounting half 63 and are adjacent to and connected to the second device mounting half 63. The two second air inlet halves 61 are respectively arranged on opposite sides of the second device mounting half 63 and are located at a position farther away from the second device mounting half 63 than the second filter module mounting half 62. The two second air inlet halves 61 are respectively adjacent to and connected to the two second filter module mounting halves 62.

[0054] Furthermore, the second splicing member 6 has second slot groups 621 on both sides (top and bottom) of the z-axis, facing the second filter module mounting half 62. Each second slot group 621 includes two slots corresponding to the HEPA filter and activated carbon filter, respectively, both along the x-axis. Unlike the first splicing member 5, the second filter module mounting half 62 is also open along the positive x-axis, forming an insertion port 620 on the side of the second splicing member 6 facing away from the first splicing member 5 and towards the outside of the air purifier.

[0055] The second splicing component 6, while forming the recessed half, also forms several protruding structures, including a second upper limit boss 622, a third lower limit boss 623, and a fourth lower limit boss 632. In the x-axis direction, the second upper limit boss 622 and the third lower limit boss 623 protrude from the upper and lower sides of the two second filter module mounting halves 62, respectively. The second slot group 621 is disposed on the second upper limit boss 622 and the third lower limit boss 623. In the z-axis direction, the fourth lower limit boss 632 protrudes below the second device mounting half 63, and the fourth lower limit boss 632 has an arc surface facing the second device mounting half 63. Additionally, the second splicing component 6 is provided with a second window 630, and the second device mounting half 63, the second window 630, and the outside are sequentially connected along the positive x-axis.

[0056] The second rear air duct half 64 is positioned above the second device mounting half 63, and the second device mounting half 63 and the second rear air duct half 64 are connected along the positive z-axis. Along the positive z-axis, the dimensions of the second rear air duct half 64 in both the y-axis and x-axis directions gradually increase, with a greater increase in the y-axis direction.

[0057] Additionally, on the second splicing component 6, a central tongue 601, a lower tongue 602, and an upper tongue 603 are provided on the end face of the aforementioned protruding structure facing the negative x-axis. The central tongue 601, lower tongue 602, and upper tongue 603 are located in the middle, lower, and upper parts of the z-axis direction, respectively. The outer contours of the central tongue 601 and lower tongue 602 are roughly "I"-shaped, while the outer contour of the upper tongue 603 is "++". The central tongue 601 is the largest, followed by the lower tongue 602, and the central tongue 601 is the smallest.

[0058] The first splicing component 5 and the second splicing component 6 are spliced ​​along the x-axis direction. Preferably, the first splicing component 5 and the second splicing component 6 are bonded together using an adhesive. Here, the x-axis direction is not only horizontal but also radial towards the air supply device 3. After the first splicing piece 5 and the second splicing piece 6 are spliced ​​together, the middle tongue 601, the lower tongue 602 and the upper tongue 603 are respectively inserted into the middle socket 501, the lower socket 502 and the upper socket 503. The two first air inlet halves 51 and the two second air inlet halves 61 are respectively connected to form two air inlets 21 facing opposite directions on the mounting body 2. The two first filter module mounting half halves 52 and the two second filter module mounting half halves 62 are respectively connected to form two filter module mounting positions 22 that are arranged opposite each other in the y-axis direction. The first device mounting half halves 53 and the second device mounting half halves 63 are connected to form a device mounting position 23. The first rear air duct half halves 54 and the second rear air duct half halves 64 are connected to form a rear air duct 24. Air inlet 21, filter module mounting position 22 and device mounting position 23 are connected sequentially along the y-axis, and device mounting position 23, rear air duct 24 and air outlet 25 are connected sequentially along the positive z-axis, that is, connected sequentially from bottom to top.

[0059] The air supply device 3 is installed in the device mounting position 23. Each filter module mounting position 22 is equipped with a HEPA filter and an activated carbon filter. The two first air duct inlets 311 of the air supply device 3 are respectively aligned with the filter modules on both sides and the air inlet 21. The first air duct outlet 312 of the air supply device 3 is connected to the second air duct inlet 248 of the rear air duct 24, thereby connecting the volute air duct 310, which serves as the front air duct, and the rear air duct 24 in sequence. The second air duct outlet 249 of the rear air duct 24 is aligned with the air outlet 25. Note that the front and rear air ducts in this invention do not refer to a relative positional relationship in a first direction, but rather to the sequential relationship of their flow along the airflow path. It should be noted that, to reduce airflow loss, ensure airflow velocity, and guarantee noise reduction, a sealing element should be added between the end face of the first air duct outlet 312 of the volute 31 and the end face of the second air duct inlet 248 of the rear air duct 24.

[0060] See Figure 2One of the disinfection modules 19 has its nozzle positioned directly opposite the lower part of the air inlet 21, see [reference]. Figure 6 Another set of disinfection modules 19 is installed within the first module mounting position 541, with its nozzle facing the air outlet 25. In this configuration, both incoming and outgoing air are effectively disinfected. After entering through the air inlet 21, the airflow passes through both the HEPA filter and the activated carbon filter, resulting in excellent filtration and purification, thus achieving excellent purification and disinfection effects. Furthermore, this invention combines the volute air duct 310 of the metal volute 31 and the rear air duct 24 of the foam mounting body 2 to form the air supply duct of the air sterilizer, achieving better noise reduction while ensuring airflow speed and volume. Additionally, after the air sterilizer is assembled, the insertion port 620 faces the door 12; opening the door 12 allows for the removal of the filter module, facilitating replacement or cleaning.

[0061] Furthermore, the main structure of this invention, formed by the air supply device 3, the mounting body 2, and the outer shell 1, is more conducive to the lightweight and compact design of the air sterilizer, and can effectively improve the power density of the product. First, see Figure 2 , Figure 6 and Figure 8 In this invention, both the filter module and the disinfection module 19 are installed on the mounting body 2. The outer shell 1 is an upper and lower enclosed structure. The outer shell 1 mainly serves as external protection. The outer shell 1 has a thin wall thickness, so even if it is made of a heavier metal material, it will not have a significant impact on the weight of the air sterilizer. The mounting body 2, which accounts for a large proportion of the volume of the air sterilizer, is made of lightweight foam material, so even though it is large in volume, it still has a lighter weight.

[0062] Furthermore, some previous air handling equipment using modular duct housings would directly install the motor and fan blades within the modular duct housing. To facilitate molding, these modular duct housings typically joined their two splicing components along the axial direction of the fan blade's rotation axis. However, for the main structure of this invention, which combines the metal volute 31 and the modular mounting body 2, joining the first splicing component 5 and the second splicing component 6 radially and horizontally, i.e., along the x-axis, effectively reduces the size of the air sterilizer in the x-axis direction. Figure 9 As shown, the second dimension w2 of the air sterilizer in this embodiment is significantly smaller than the first dimension w1 in the y-axis direction. Conversely, choosing axial splicing will increase the dimension of the air sterilizer in the x-axis direction, which will be further explained below in conjunction with the second embodiment of the air handling equipment.

[0063] Second embodiment of air handling equipment

[0064] See Figure 11In this embodiment, the two splicing parts of the mounting body are spliced ​​along the y-axis direction, which is the axial direction of the rotation axis of the air supply device.

[0065] Comparison of the first and second embodiments of the air handling equipment

[0066] Comparison Figure 10 and Figure 11 In conjunction with other accompanying drawings of the first embodiment, it can be seen that the main difference between the first embodiment and the second embodiment is that: in the first embodiment, the splicing direction of the first splicing member 5 and the second splicing member 6 of the mounting body 2 is radial and horizontal towards the air supply device 3, that is... Figure 10 The x-axis direction is shown, while in the second embodiment, the splicing direction of the two splicing parts of the mounting body is the axial direction of the air supply device and is horizontal, that is... Figure 11 The y-axis direction is shown.

[0067] The splicing components not only need to be spliced ​​in a preset direction, but also need to form a certain positioning fit with the air supply device. Therefore, while the two splicing components of the mounting body are spliced ​​in one direction, the air supply device needs to be restricted on both sides in another horizontal direction perpendicular to the splicing direction. For example, in the first embodiment, when the first splicing component 5 and the second splicing component 6 are spliced ​​along the x-axis, the air supply device 3 needs to be restricted from two opposite directions along the y-axis. In the second embodiment, when the two splicing components are spliced ​​along the y-axis, the air supply device 3' needs to be restricted from two opposite directions along the x-axis. Assume that the mounting body of both the first and second embodiments needs to be provided with a part having a fifth dimension w5 to restrict the air supply device.

[0068] Since the mounting body serves as the main structure for the internal components of the air purifier, the larger filter module needs to be installed on it. This filter module is positioned directly opposite the air duct inlet of the air supply unit. Therefore, see [link / reference needed]. Figure 10 and Figure 11 Regardless of whether it is the first or second embodiment, the mounting body will have a portion with a fourth dimension w4 in the y-axis direction for mounting the filter module. Since the outer shell is a thin-walled component, the first dimension w1 of the air sterilizer in the y-axis direction is approximately equal to the sum of the third dimension w3 and the two fourth dimensions w4.

[0069] See Figure 10 In the first embodiment, the limiting portion 29 for restricting the air supply device 3 from the y-axis direction is actually formed on the part for mounting the filter module. Therefore, the setting of the limiting portion 29 does not increase the size of the air sterilizer in the y-axis direction. Furthermore, in combination with... Figure 6 , Figure 7 and Figure 10The first window 530 and the second window 630 on the first splicing piece 5 and the second splicing piece 6, respectively, corresponding to the device mounting position 23, are used to avoid the maximum size of the volute 31 in the x-axis direction. This arrangement makes the second dimension w2 of the air sterilizer in the x-axis direction close to the size of the volute 31.

[0070] See Figure 11 In the second embodiment, similarly, in the y-axis direction, the first dimension w1 of the air sterilizer is approximately the sum of the third dimension w3 and two fourth dimensions w4. However, in the x-axis direction, since the mounting body needs to be equipped with two limiting parts 29', the size of the air sterilizer is at least two fifth dimensions w5 based on the aforementioned second dimension w2.

[0071] It is evident that, in this invention, the air supply device with a duct shell, the mounting body, and the outer shell are arranged sequentially from the inside out, and the mounting body is used as the mounting body for the filter module and the disinfection module. Splicing the splicing parts radially is more conducive to miniaturizing the product.

[0072] Additionally, see Figure 9 In the first embodiment, the second dimension w2 of the air sterilizer in the x-axis direction is smaller than the first dimension w1 in the y-axis direction. However, the dimension of the second air duct outlet 312 of the volute 31 in the x-axis direction is larger than its dimension in the y-axis direction. To further improve the air volume and air delivery range, the present invention controls the rate of change of the dimensions of the rear air duct 24 in the x-axis and y-axis directions. That is, from bottom to top, the rate of increase of the rear air duct 24 in the y-axis direction is greater than the rate of increase in the x-axis direction. This makes the dimension of the second air duct outlet 249 in the y-axis direction larger than its dimension in the x-axis direction, thereby making the width and height directions of the second air duct outlet 249 consistent with the width and height directions of the air sterilizer, resulting in a larger air outlet for the air sterilizer.

[0073] It is evident that this invention improves air delivery performance while maintaining a small size and lightweight design.

[0074] Third embodiment of air handling equipment

[0075] See Figure 12 and Figure 13 Compared to the first embodiment, this embodiment adds an air guide 8 and an air outlet grille 9 above the second air duct outlet 719, the purpose of which is to realize the conversion of the air outlet direction of the air sterilizer.

[0076] Similar to the first embodiment, the second air duct outlet 719 is upward-facing. The air guide 8 is fixedly positioned directly opposite the second air duct outlet 719 of the rear air duct 71. The air guide 8 and the mounting body 7 form the air outlet 809 of this embodiment. The air outlet 809 is a wraparound outlet, and its airflow direction is vertical or inclined to various vertical directions, such as various horizontal directions. A reversing air duct 80 is formed between the air outlet 809 and the second air duct outlet 719.

[0077] The lower side of the air guide 8 has a downward-facing air guide surface 81 facing the second air duct outlet 719 and the reversing air duct 80. The air guide surface 81 includes a first air guide portion 811 and a second air guide portion 822. The first air guide portion 811 is a spherical cap surface and is located at the center of the bottom of the air guide 8. The second air guide portion 822 surrounds the outer periphery of the first air guide portion 811 and gradually extends upwards at an angle. The second air guide portion 822 is the side surface of a frustum. In this embodiment, the air guide surface 81, the reversing air duct 80, and the air outlet 809 are all arranged around each other. A portion of the reversing air duct 80 surrounds the outer periphery of the air guide surface 81, and the air outlet 809 surrounds the outer periphery of the reversing air duct 80. The air outlet grille 9 is provided with a plurality of curved air guide blades 91. The curvature of the air guide blades 91 is consistent with the reversing trend of the reversing air duct 80, that is, the air guide blades 91 gradually bend and extend from the upward direction to the horizontal direction.

[0078] Furthermore, multiple disinfection modules 19 can be evenly arranged circumferentially along the air guide 8 on the second air guide 822. Compared with the first embodiment, since the air outlet position has changed in this embodiment, placing the disinfection modules 19 on the second air guide 822, which is closer to the air outlet 809, is more conducive to improving the disinfection effect.

[0079] In other embodiments, the mounting body may also be composed of three or more interlocking pieces. Naturally, fewer interlocking pieces result in fewer seams, making assembly easier and sealing the seams less difficult, while also reducing noise.

[0080] In other embodiments, the mounting body can also be made of other materials, such as lightweight plastic. Preferably, the unit weight of the molding material of the mounting body should be less than the unit weight of the molding material of the duct housing. Of course, in some cases, when the unit weight of the molding material of the outer shell is less than that of the molding material of the mounting body, and the outer shell still meets the strength requirements, a lighter material can be used for the outer shell; for example, the outer shell can be made of carbon fiber while the mounting body is made of plastic. Furthermore, when using a plastic molding mounting body, it is possible to consider setting the mounting body as a hollow structure composed of a multi-ribbed network, further reducing weight while ensuring sufficient structural strength.

[0081] In other embodiments, the housing is not provided with a door, and the housing is designed to be more easily assembled and disassembled. When the filter module needs to be replaced, the housing can be lifted to expose the mounting body and the filter module on it.

[0082] In other embodiments, the filtration module includes one or more of the following: a common filter, a HEPA filter, an activated carbon filter, a plasma filter, an ozone filter, and a high-voltage electrostatic filter; it may also include at least two filters with different filtration accuracies.

[0083] In other embodiments, the disinfection module may be one or more of the following active disinfection modules: ultraviolet module, high temperature module, positive and negative ion generator, and low temperature plasma generator.

[0084] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
