Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to an air supply device. Background Technology

[0002] For specific use cases such as studying, reading, and meetings, air supply devices are often integrated with office supplies or furniture. For example, a desktop air supply device can be configured to provide directional airflow when the user is near the tabletop. A typical desk with air supply functionality includes a tabletop and a housing beneath it. The air supply unit that generates airflow is located inside the housing, while the air outlet that outputs airflow is located on the tabletop, creating a comfortable airflow for the user when using the desk.

[0003] Compared to other air supply devices installed in home spaces, such as exhaust fans and air conditioners, this type of air supply device has an air outlet that is closer to the user. Therefore, users are more sensitive to the air speed output through the air outlet. If the air speed is too high, it will cause discomfort to the user. Utility Model Content

[0004] In view of the above-mentioned technical problems, the present invention provides an air supply device that can reduce the air outlet speed to improve the user experience.

[0005] This utility model provides an air supply device, comprising: a main body, the main body including a basket disposed at the bottom of a table, the basket having an internal partition to divide the internal space of the basket into a first space and a second space, the partition having a vent; an air supply section disposed in the second space, the vent being connected to the air outlet side of the air supply section; and a windbreak wall disposed in the first space facing the vent, wherein, with the plane where the vent is located as the projection plane, the projection of the vent and the projection of the windbreak wall at least partially overlap in a projection along a direction orthogonal to the projection plane, and the area of ​​the overlapping portion is configured to be greater than or equal to half the cross-sectional area of ​​the vent.

[0008] In some illustrative embodiments, the aforementioned air outlet and the aforementioned ventilation opening are offset.

[0009] In some illustrative embodiments, the air outlet and the ventilation opening are at least partially opposite to each other, and the windbreak wall is located between the air outlet and the ventilation opening.

[0010] In some illustrative embodiments, the air supply device further includes an air guide mechanism disposed on the tabletop and covered by the air outlet. The air guide mechanism has a desktop air outlet, which is disposed downstream of the air outlet and is at least partially offset from the air outlet.

[0011] In some illustrative embodiments, the inclined portion includes: a first inclined plate covering at least a portion of the air outlet and extending along a direction forming a first angle with the tabletop; and a second inclined plate extending along a direction forming a second angle with the tabletop; wherein the second inclined plate is disposed below the first inclined plate, and the first inclined plate and the second inclined plate define the desktop air outlet.

[0012] In some illustrative embodiments, the air guiding mechanism further includes an air guiding plate disposed between the first inclined plate and the second inclined plate, the air guiding plate being configured as a sheet-like structure extending from the downstream side to the upstream side of the airflow direction.

[0013] In some illustrative embodiments, the air guide vane includes a vertical air guide vane, which is configured as a sheet-like structure perpendicular to the tabletop and extends at intervals along the extending direction of the tabletop air outlet.

[0015] In some illustrative embodiments, the air supply device further includes an air handling unit disposed inside the aforementioned housing and configured to handle the air passing through the aforementioned air handling device.

[0016] In some illustrative embodiments, a third space is further provided inside the aforementioned housing, the third space having a bypass ventilation passage communicating with the aforementioned second space; wherein the aforementioned air handling unit is disposed in the aforementioned third space.

[0017] In some illustrative embodiments, the air treatment unit has an odor generating module that is adapted to emit odor factors.

[0018] As can be seen from the above technical solution, the air supply device of this utility model has at least the following beneficial effects:

[0019] By setting up a windbreak wall facing the vent in the first space, the high-speed airflow entering the first space through the vent will hit the windbreak wall, thereby reducing the wind speed and making the airflow diffuse and fill the first space.

[0046] First Embodiment

[0047] Figure 1 This is a partial cross-sectional view of an air supply device according to an illustrative first embodiment of the present invention. Figure 2 yes Figure 1 The diagram shows the airflow direction of the air supply device.

[0048] This utility model provides an air supply device, referring to... Figure 1 and Figure 2 As shown, the system includes a main body 100, an air supply unit 200, and a windbreak wall 108. The main body 100 includes a basket 105 disposed at the bottom of a tabletop 101. The basket 105 has an internal partition 1056 that divides its internal space into a first space 1051 and a second space 1052. The partition 1056 has a ventilation opening 1057. The air supply unit 200 is disposed in the second space 1052, and the ventilation opening 1057 is connected to the air outlet side of the air supply unit 200. The windbreak wall 108 is disposed in the first space 1051 facing the ventilation opening 1057. Using the plane where the ventilation opening 1057 is located as a projection plane, in a projection along a direction orthogonal to the projection plane, the projection of the ventilation opening 1057 and the projection of the windbreak wall 108 at least partially overlap, and the area of ​​the overlapping portion is configured to be greater than or equal to half the cross-sectional area of ​​the ventilation opening 1057.

[0049] In this embodiment, a windbreak wall 108 is provided within the first space 1051. This windbreak wall 108 is positioned opposite the vent 1057, and the projected area of ​​the portion of the windbreak wall 108 overlapping with the vent 1057 is configured to be at least half the cross-sectional area of ​​the vent 1057. With this configuration, when the high-speed airflow generated by the air supply unit 200 enters the first space 1051 through the vent 1057, it impacts the windbreak wall 108. This reduces the airflow velocity and allows the airflow to diffuse and fill the first space 1051 instead of being directly expelled outwards. This avoids the excessive cold sensation caused by high-speed airflow blowing directly onto the user's face or other parts, as is common in related technologies, thus improving user comfort. Furthermore, after being diffused and slowed by the windbreak wall 108, the high-speed airflow forms a relatively stable airflow, reducing interference between the airflow and other components within the table, lowering turbulence and noise levels, and further enhancing the user experience. Furthermore, the design of the windbreak 108 allows airflow to diffuse fully before being slowly blown out through the air outlet 1011, creating a gentle and uniform breeze. This avoids excessively high local wind speeds, providing a more natural and comfortable breeze, and is suitable for prolonged use. In other embodiments, the windbreak 108 can also be configured such that the projected area of ​​the portion overlapping with the vent 1057 is at least two-thirds of the cross-sectional area of ​​the vent 1057. Alternatively, the projection of the windbreak 108 can be set to completely overlap with the projection of the vent 1057.

[0050] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, the main body 100 is configured as a table-like structure. Specifically, the upper surface of the tabletop 101 can be used as a desktop 1012 for placing items and for use by users in scenarios such as studying, reading, and meetings. Depending on the usage scenario, the desktop 1012 can be configured to be roughly parallel to the horizontal plane, or it can be configured to form a certain angle with the horizontal plane for comfort, lighting, or other requirements. For example, it can be configured to 12° to 24°. This helps users maintain a natural posture and reduces neck and back pressure caused by prolonged head-down posture.

[0051] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, in addition to the tabletop 101, the main body 100 also has table legs or similar support structures for supporting the tabletop 101.

[0052] For example, the basket 105 can be used as part of the support structure, that is, the basket 105 can be installed on one side of the lower surface of the table 101, while the other side of the table 101 without the basket 105 can be provided with corresponding table legs so that the table 101 is supported on the work surface (such as the ground).

[0053] Alternatively, a long table leg 104 may be provided on the side of the tabletop 101 where the basket 105 is not installed, while a short table leg 106 may be provided at the bottom of the basket 105, so that the sum of the heights of the short table leg 106 and the basket 105 is approximately the same as the height of the long table leg 104.

[0054] For example, the main body 100 may include, but is not limited to, having four table legs, while the basket 105 located at the bottom of the tabletop 101 is situated between the four table legs.

[0055] Of course, depending on the shape of the tabletop 101 and / or the positional relationship of the basket 105 relative to the tabletop 101, the number of table legs can be 2, 3, 4, 5, 6, or any other arbitrary number, preferably such that the main body 100 can be stably supported on the work surface. It should be understood that the embodiments of this utility model are not limited thereto.

[0056] For example, the main body 100 may not include the tabletop 101 and table legs. In other words, the air supply device can be integrated into the tabletop 101 of an ordinary table in a modular structure.

[0057] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, the main body 100 also includes a shelf disposed on the upper surface of the tabletop 101. Specifically, the shelf mainly includes a baffle 103 and a shelf 102. The baffle 103 is disposed on the edge of at least one end of the tabletop 101 and protrudes from the tabletop 1012 of the tabletop 101. The shelf 102 is disposed on the baffle 103 in a direction orthogonal to it, and is configured to be substantially parallel to and spaced apart from the tabletop 1012. For example, the baffle 103 may be disposed on the edges of at least three adjacent sides of the tabletop 101, and the shelf 102 may be disposed on the top of the baffle 103.

[0058] For ease of explanation, in the embodiments of this utility model, the side of the main body 100 used by the user (such as the side facing the user when using the main body 100) is referred to as the front, and the side away from the user is referred to as the rear. In the above embodiments, the side of the main body 100 with the shelf can be referred to as the rear of the main body 100, and the side opposite the shelf can be referred to as the front of the main body 100, so that the user can stand or sit in front of the main body 100 and use the desktop 1012 for work.

[0059] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, the basket 105 and the table 101 form the outer outline of the air supply device. Furthermore, the portion enclosed by the basket 105 and the table 101 forms an internal space for accommodating the air supply unit 200.

[0060] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, the basket 105 includes, but is not limited to, a hollow box structure configured as a roughly cubic shape, specifically including a top surface (which may be the lower surface of the tabletop 101), a bottom surface, and a side surface connecting the top and bottom surfaces. The bottom surface is located below the top surface and on the opposite side. Short table legs 106 are located below the bottom surface of the basket 105 to support the air supply device, maintaining a certain distance between the basket 105 and the work surface. The sides of the basket 105 include a front side located in front of the table, a rear side located opposite the front side, a left side connecting the front and rear sides, and a right side located opposite the left side.

[0061] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, a partition 1056 is provided inside the basket 105 to divide the internal space of the basket 105 into two independent spaces: a first space 1051 and a second space 1052. Specifically, at least a portion of the partition 1056 is arranged horizontally to divide the internal space of the basket 105 into an upper first space 1051 and a lower second space 1052. Furthermore, the partition 1056 is also provided with a vent 1057. Based on the aforementioned first space 1051 and second space 1052, an air supply unit 200 is disposed in the second space 1052 and connected to the first space 1051 through the vent 1057, so that the airflow generated by the air supply unit 200 can only enter the first space 1051 through the vent 1057.

[0062] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, the orthographic projection of the windbreak wall 108 onto the plane where the vent 1057 is located covers at least half of the vent 1057. This can be understood as the windbreak wall 108 at least obscuring half of the vent 1057 when viewed vertically from the side of the windbreak wall 108 toward the vent 1057. Furthermore, the orthographic projection of the windbreak wall 108 onto the plane where the vent 1057 is located covers the entire vent 1057, meaning that the windbreak wall 108 completely obscures the vent 1057 when viewed vertically from the side of the windbreak wall 108 toward the vent 1057. Moreover, there is a certain distance between the windbreak wall 108 and the vent 1057. It should be understood that the embodiments of this utility model are not limited to this.

[0063] For example, the partition 1056 can also be arranged vertically to divide the internal space of the basket 105 into a first space 1051 and a second space 1052 arranged to the left and right.

[0064] Alternatively, the partition 1056 may be arranged in other directions to divide the internal space of the basket 105 into an irregularly arranged first space 1051 and a second space 1052.

[0065] According to an embodiment of the present invention, a windbreak wall 108 is formed on the inner wall of the side of the table 101 facing the ventilation opening 1057.

[0066] Based on the above embodiments, the top surface of the basket 105 can be understood as the lower surface of the tabletop 101. That is, at least a portion of the top surface of the basket 105, a portion of the side surface of the basket 105, and at least a portion of the partition plate 1056 enclose to form a first space 1051. Similarly, at least a portion of the bottom surface of the basket 105, a portion of the side surface of the basket 105, and at least a portion of the partition plate 1056 enclose to form a second space 1052.

[0067] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, since the top surface of the basket 105 (i.e., the lower surface of the tabletop 101) is opposite to the ventilation opening 1057, the top surface of the basket 105 can be used as the aforementioned windbreak wall 108. This avoids the need for a more complex windbreak wall 108 structure within the basket 105. The top surface of the basket 105 may include, but is not limited to, a flat surface structure, specifically, it may be configured to be parallel to a horizontal plane. It should be understood that the embodiments of this utility model are not limited to this.

[0068] For example, the windbreak wall 108 can also be the wall surface of other plate-like structures disposed between the vent 1057 and the top surface of the basket 105.

[0069] For example, in addition to being configured as a wall structure parallel to the horizontal plane, the windbreak wall 108 can also be configured to form a certain angle with the horizontal plane, specifically an acute angle with the horizontal plane, so that the high-speed airflow can be effectively slowed down and diffused.

[0070] According to an embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the air supply device has an air outlet 1011 and an air inlet 1054. The air outlet 1011 is located on the table 101 and communicates with the first space 1051, while the air inlet 1054 is located on the basket 105 and communicates with the second space 1052.

[0071] According to an illustrative embodiment of the present invention, the air outlet 1011 and the ventilation opening 1057 are offset.

[0072] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, an air inlet 1054 is disposed on the basket 105 to allow air to enter the interior space of the basket 105 from the external space, specifically the second space 1052 mentioned above. More specifically, the air inlet 1054 may be disposed on, but is not limited to, the front side of the basket 105. Furthermore, the main body 100 also includes a decorative panel disposed on the front side of the air inlet 1054, and the decorative panel is spaced apart from the air inlet 1054 so that air from the external space can pass through the gap between the decorative panel and the air inlet 1054 and enter the air inlet 1054.

[0073] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, a first air inlet gap 1055 is provided between the wall surface of the decorative panel facing the air inlet 1054 and the air inlet 1054, and a second air inlet gap is provided between the side wall surface of the decorative panel and the air inlet 1054. Similarly, depending on the shape and / or structure of different decorative panels, the decorative panel may also include a third air inlet gap at the bottom, etc.

[0074] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, the air outlet 1011 is disposed on the tabletop 101 and penetrates the lower surface of the tabletop 101 to connect with the first space 1051, allowing air to be blown outward from the first space 1051. Specifically, the air outlet 1011 may be located, but is not limited to, at the rear of the tabletop 101, and can be covered by the aforementioned shelf. The gap between the shelf plate 102 and the desktop 1012 forms the air outlet 1011 on the desktop 1012. Thus, the air blown out through the first space 1051 is blocked and redirected by the shelf plate 102, and further guided to the front of the tabletop 101 facing the user.

[0075] In the above-described implementation, the air outlet 1011 is located on one side of the windbreak wall 108, and the air outlet 1011 and the ventilation opening 1057 are completely misaligned.

[0076] According to another illustrative embodiment of the present invention, the air outlet 1011 and the ventilation opening 1057 are at least partially opposite to each other, and the windbreak wall 108 is located between the air outlet 1011 and the ventilation opening 1057.

[0077] For example, the windbreak wall 108 can be a wall of the air outlet 1057 facing the air vent 1017 and the air vent 1057. In addition, the air outlet 1011 can also be located above the windbreak wall 108, and the windbreak wall 108 can block at least a part of the air vent 1057.

[0078] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, the air supply device also includes an air conditioning module 1058 disposed downstream of the air inlet 1054. The air conditioning module 1058 can be understood as regulating one or more of the following air parameters: temperature, humidity, and air quality. For example, the air conditioning module 1058 may include, but is not limited to, a filter used to filter the flowing air to achieve a purification effect. This filter may include, but is not limited to, a pre-filter, a high-efficiency filter, an activated carbon filter, or other mechanisms that use physical or chemical means to filter air.

[0079] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, the air supply unit 200 includes, but is not limited to, a snail shell, fan blades, and a motor. Specifically, the snail shell accommodates the fan blades and includes a top surface with an air inlet 1054, a bottom surface opposite the top surface, and a side surface connecting the top and bottom surfaces. The top, bottom, and side surfaces of the snail shell together form an air outlet 1011. The fan blades are housed within the snail shell, and the motor is connected to them. Furthermore, the bottom surface of the snail shell has an opening, and the motor is located on this opening, specifically at the opening, and connected to the fan blades via a shaft. The air inlet side of the snail shell in the air supply unit 200 is configured to face away from the air inlet 1054; specifically, the bottom surface of the snail shell may face the air inlet 1054. The air outlet side of the snail shell is located in the circumferential direction of the fan blade shaft.

[0080] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, the vent 1057, located on the partition 1056, connects the air supply section 200 and the first space 1051, allowing air to be supplied from the air supply section 200 into the first space 1051. The connection of the vent 1057 to the air supply section 200 can be understood as the vent 1057 connecting to the snail shell air outlet side of the air supply section 200. Specifically, this connection can be direct or indirect via a duct or other air duct structure.

[0081] Regarding the aforementioned air supply device, the housing 105 of the air supply device is located below the tabletop 101 and is connected to the airflow path within the air supply device via an air outlet 1011. The housing 105 contains a first space 1051 and a second space 1052. The first space 1051 is connected to the external space via the air outlet 1011, allowing air to be blown outwards. The second space 1052 is connected to the space outside the housing 105 via an air inlet 1054, allowing air to enter the second space 1052. The second space 1052 is connected to the first space 1051 via a vent 1057, and the air supply unit 200 is connected to the vent 1057. Specifically, the snail-shell-shaped air outlet 1011 of the air supply unit 200 is connected to the vent 1057.

[0082] When the air supply device is running, refer to Figure 2 As shown, the fan blades rotate under the drive of the motor, and air is drawn into the housing 105 by the rotation of the fan blades. Specifically, the air inlet 1054 is located on the front side of the housing 105, and a decorative panel is located upstream of the air inlet 1054 and covers the air inlet 1054. A first air inlet gap 1055 and a second air inlet gap are provided between the decorative panel and the air inlet 1054. Air enters the air inlet 1054 from outside the housing 105 through the first air inlet gap 1055 and the second air inlet gap, and then enters the second space 1052. Part of the air entering the second space 1052 is drawn into the snail shell air inlet 1054, and another part is drawn into the snail shell opening, thus entering the snail shell. Then, guided by the snail shell, it is blown out towards the snail shell air outlet 1011. Since the snail shell air outlet 1011 is connected to the ventilation port 1057 through the pipe, the air in the second space 1052 is sent from the snail shell air outlet 1011 to the first space 1051 through the pipe and the ventilation port 1057, and then sent to the outside of the basket 105 through the air outlet 1011 set on the table 1012.

[0083] Therefore, air can be supplied to the user using the table without occupying space on the user's desktop 1012. Furthermore, since an air conditioning module 1058 is provided downstream of the air inlet 1054, the air will be regulated before entering the air supply section 200, including but not limited to filtration, purification, and disinfection, thereby reducing the entry of impurities such as dust into the air supply section 200, thus providing clean air to the user and reducing the adverse effects of impurities on the lifespan of the air supply section 200.

[0084] When the air in the second space 1052 forms a high-speed airflow under the action of the fan blades and is blown out through the vent 1057 into the first space 1051 and the air outlet 1011, since a windbreak wall 108 is provided on the opposite side of the vent 1057 in the first space 1051, and the windbreak wall 108 covers at least half of the area of ​​the vent 1057, most of the high-speed airflow blowing out of the vent 1057 will collide with the windbreak wall 108, slowing down the wind speed and flowing to fill other areas in the first space 1051, rather than being directly blown out to the air outlet 1011. When the air fills most of the area of ​​the first space 1051, the air pressure in the first space 1051 will increase compared to the second space 1052 and the space outside the basket 105. At this time, the air in the first space 1051 will be slowly blown out of the basket 105 through the air outlet 1011 under the action of air pressure, forming a gentle breeze, and then delivered to the user.

[0085] As a result, most of the airflow that is blown out at high speed from the vent 1057 is suppressed from blowing directly from the air outlet 1011 to the outside of the basket 105 towards the user, causing discomfort to the user.

[0087] According to an embodiment of the present invention, referring to Figure 3 and Figure 4 As shown, the air supply device also includes an air guiding mechanism. The air guiding mechanism is disposed on the tabletop 101 and covered by the air outlet 1011. The air guiding mechanism has a tabletop 1012 air outlet 1011, which is disposed on the downstream side of the air outlet 1011 and is at least partially offset from the air outlet 1011.

[0088] In some illustrative embodiments, reference is made to Figure 3 and Figure 4 As shown, the air outlet 1011 of the desktop 1012 is located outside the basket 105 of the air supply device and downstream of the air outlet 1011. Specifically, it can be formed in the gap between the shelf 102 of the shelf and the desktop 1012, as described in the above embodiment. After the air is blown out from the air outlet 1011, it is then blown out into the space outside the basket 105 through the air outlet 1011 of the desktop 1012.

[0089] According to an embodiment of the present invention, referring to Figure 3 and Figure 4As shown, the air outlet 1011 of the desktop 1012 has an inclined portion 1023 that is inclined to the desktop 101 and a parallel portion 1022 that is parallel to the desktop 101. The inclined portion 1023 is located upstream of the parallel portion 1022 along the airflow direction.

[0090] According to an embodiment of the present invention, referring to Figure 3 and Figure 4 As shown, the inclined portion 1023 includes a first inclined plate 10231 and a second inclined plate 10232. The first inclined plate 10231 covers at least a portion of the air outlet 1011 and extends along a direction forming a first angle with the tabletop 101. The second inclined plate 10232 extends along a direction forming a second angle with the tabletop 101. The second inclined plate 10232 is disposed below the first inclined plate 10231, and the air outlet 1011 of the tabletop 1012 is defined between the first inclined plate 10231 and the second inclined plate 10232.

[0091] In some illustrative embodiments, reference is made to Figure 3 and Figure 4 As shown, the first inclined plate 10231 and the second inclined plate 10232 have different extending directions. Specifically, the first included angle is configured to be greater than the second included angle, so that the side of the inclined portion 1023 facing the air outlet 1011 of the table 101 forms a wide-mouth side, while the side away from the air outlet 1011 forms a narrow-mouth side, and the parallel portion 1022 is formed on the narrow-mouth side.

[0092] Figure 5 yes Figure 4 A schematic diagram of the air guide vanes of the air guide mechanism shown from the front view. Figure 6 yes Figure 5 A schematic diagram showing the top view of the air guide vane.

[0093] To further guide the airflow output from the air outlet 1011 of the desktop 1012, the shelf also has a lower parallel plate disposed on the desktop 101 and an upper parallel plate located above the lower parallel plate. The upper and lower parallel plates are parallel to each other and located downstream of the parallel section 1022, so that the airflow output through the parallel section 1022 can be further guided in a direction parallel to the desktop 1012.

[0094] According to an embodiment of the present invention, the air guiding mechanism further includes an air guiding plate 1024 disposed between the first inclined plate 10231 and the second inclined plate 10232, the air guiding plate 1024 being configured as a sheet-like structure extending from the downstream side to the upstream side of the airflow direction.

[0095] According to an embodiment of the present invention, referring to Figure 5 and Figure 6As shown, the air guide 1024 includes a vertical air guide 10241. The vertical air guide 10241 is configured as a sheet-like structure perpendicular to the tabletop 101 and is spaced apart along the extension direction of the air outlet 1011 of the tabletop 1012.

[0096] In some illustrative embodiments, reference is made to Figure 5 and Figure 6 As shown, the air guide plate 1024 is disposed on the upstream side of the air outlet 1011 of the desktop 1012, and is a sheet-like shape extending from the upstream side to the downstream side of the air outlet 1011 of the desktop 1012. The air guide plate 1024 divides the air outlet 1011 of the desktop 1012 into two or more sections in the horizontal direction. Specifically, the air guide plate 1024 is disposed at the downstream end of the inclined portion 1023 and located at the upstream end of the parallel portion 1022. It should be understood that the embodiments of this utility model are not limited thereto.

[0097] For example, the air guide vane 1024 can also extend to the downstream end of the parallel portion 1022, that is, to the air outlet 1011 of the desktop 1012.

[0098] In some illustrative embodiments, reference is made to Figure 5 and Figure 6 As shown, the air guide 1024 includes a vertical air guide 10241 and an inclined air guide 10242. The vertical air guide 10241 is disposed perpendicular to the plane of the air outlet 1011 of the desktop 1012, and the inclined air guide 10242 is disposed inclined toward one side of the vertical air guide 10241. Further, the vertical air guide 10241 is disposed on the side of the inclined portion 1023 that is closer to the air supply section 200 relative to the air outlet 1011 of the desktop 1012, and the vertical air guide 10241 is disposed on the side of the inclined portion 1023 that is away from the air supply section 200 relative to the air outlet 1011. The extension line of the vertical air guide 10241 toward the air outlet 1011 disposed on the desktop 101 intersects the air outlet 1011 at the end of the air outlet 1011 that is away from the air supply section 200.

[0099] According to an embodiment of the present invention, referring to Figure 5 and Figure 6 As shown, the air supply unit 200 is located on one side of the housing 105, offset from the center of the air outlet 1011 of the tabletop 1012. The air supply device also includes a first inclined air guide vane and a second inclined air guide vane. The first inclined air guide vane is located on the side of the vertical air guide vane 10241 near the air supply unit 200, and the extending direction of the first inclined air guide vane forms a third angle with the tabletop 101. The second inclined air guide vane is located on the side of the vertical air guide vane 10241 away from the air supply unit 200, and the extending direction of the second inclined air guide vane forms a fourth angle with the tabletop 101. The third and / or fourth angles are configured as acute angles.

[0100] In some illustrative embodiments, reference is made to Figure 5 and Figure 6 As shown, the first inclined air guide vane is disposed on the side of the vertical air guide vane 10241 closer to the air supply section 200, and the third included angle formed by its intersection with the plane of the air outlet 1011 on the side closer to the vertical air guide vane 10241 is an acute angle. Furthermore, the second inclined air guide vane is disposed on the side of the vertical air guide vane 10241 farther from the air supply section 200, and the fourth included angle formed by its intersection with the plane of the air outlet 1011 on the side closer to the vertical air guide vane 10241 is an acute angle.

[0101] In this implementation method, refer to Figure 5 and Figure 6 As shown, since the air outlet 1011 of the desktop 1012 is located at the end of the shelf away from the rear side of the tabletop 101, the shelf is positioned above the air outlet 1011. When airflow is blown out from the air outlet 1011, most of the air will impact the shelf, potentially generating turbulence and noise. Therefore, in this embodiment, an inclined portion 1023 is provided downstream of the air outlet 1011, tilting upwards towards the air outlet 1011 of the desktop 1012. The inclined portion 1023 includes a first inclined plate 10231 located opposite the air outlet 1011, and a second inclined plate 10232 closer to the air outlet 1011 than the first inclined plate 10231. When airflow is blown out from the air outlet 1011, a portion of the air will impact the first inclined plate 10231 and, guided by the first inclined plate 10231, will be blown out towards the air outlet 1011 of the desktop 1012, thereby suppressing the generation of turbulence and noise. Furthermore, due to the presence of the second inclined plate 10232, a portion of the air blown out from the air outlet 1011 will be blown along the second inclined plate 10232 toward the air outlet 1011 on the tabletop 1012, which can further suppress the generation of turbulence and noise.

[0102] Furthermore, since the extension lines of the first inclined plate 10231 and the second inclined plate 10232 towards the air outlet 1011 of the desktop 1012 intersect at a single point, an air duct that gradually narrows towards the air outlet 1011 of the desktop 1012 is formed. This allows the airflow blowing from the air outlet 1011 to be more concentrated. However, when the airflow blows out along the inclined portion 1023 towards the air outlet 1011 of the desktop 1012, the direction of the airflow is inclined upwards, which may directly blow towards the user's head or face, potentially causing discomfort. Therefore, in this embodiment, a parallel portion 1022 is further provided on the downstream side of the inclined portion 1023. The parallel portion 1022 is provided on the downstream side of the inclined portion 1023, protruding and extending from the downstream end of the inclined portion 1023 towards the air outlet 1011 of the desktop 1012, and is parallel to the desktop 1012. The air blown upwards from the inclined section 1023 will be guided by the parallel section 1022 and blown out in an airflow direction parallel to the desktop 1012, thereby suppressing discomfort caused by the airflow blowing directly onto the user's head or face. Furthermore, after being blown out from the parallel section 1022 through the air outlet 1011 of the desktop 1012, most of the airflow will diffuse towards the user in a direction parallel to the desktop 1012, and then diffuse upwards after contacting the user, providing a gentle and comfortable breeze while delivering air to the user.

[0103] The second embodiment of this utility model will be described next, wherein the same structure as the first embodiment will not be repeated.

[0104] Second Embodiment

[0105] Figure 7 This is a partial cross-sectional view of an air supply device according to an illustrative second embodiment of the present invention.

[0106] According to the air supply device provided by this utility model, referring to Figure 7 As shown, the system includes a main airflow path connecting the air inlet 1054 and the air outlet 1011. A vent 1057 is located in the main airflow path, between the air inlet 1054 and the air outlet 1011. An air supply unit 200 is also located in the main airflow path, between the air inlet 1054 and the vent 1057. In other words, after air enters the second space 1052 through the air inlet 1054, it sequentially passes through the air supply unit 200, the vent 1057, and the first space 1051, finally exiting through the air outlet 1011, thus forming the main airflow path of this air supply device. In this embodiment, the air conditioning module 1058 is located in the main airflow path, specifically between the air inlet 1054 and the snail-shell air inlet 1054.

[0107] It should be noted that, based on similar concepts, this embodiment has features similar to or the same as those in the first embodiment described above, and also has similar or the same functions based on these features. Therefore, it will not be described again.

[0108] According to an embodiment of the present invention, the air supply device further includes an air handling unit 107. The air handling unit 107 is disposed inside the housing 105 and configured to process the air passing through the air handling device. The air processing includes at least one of cooling, heating, dehumidification, purification, and fragrance enhancement.

[0109] Figure 8 yes Figure 7 The diagram shows the airflow direction of the air supply device.

[0110] According to an embodiment of the present invention, referring to Figure 8 As shown, a third space 1053 is also provided inside the housing 105, and the third space 1053 has a bypass ventilation passage 109 that communicates with the second space 1052. The air handling unit 107 is provided in the third space 1053.

[0111] In some illustrative implementations, refer to Figure 8 As shown, the basket 105 is also provided with other partitions 1056 to divide at least a portion of the internal space of the basket 105 into a third space 1053 that is isolated from the first space 1051 and the second space 1052. In detail, the third space 1053 includes, but is not limited to, being disposed above the second space 1052 and in front of the first space 1051.

[0112] In some illustrative embodiments, reference is made to Figure 8 As shown, the third space 1053 and the second space 1052 are connected by a bypass ventilation path 109, wherein the bypass ventilation path 109 includes a bypass air inlet 1091 and a bypass air outlet 1092 disposed in the second space 1052.

[0113] In some illustrative embodiments, reference is made to Figure 8 As shown, the bypass air inlet 1091 is located at the upper part of the second space 1052. Specifically, it can be a partition 1056 that isolates the second space 1052 and the third space 1053 and penetrates through the partition 1056, so that the second space 1052 is directly connected to the third space 1053, thereby allowing air to enter the third space 1053 from the second space 1052. It is understood that in other embodiments, the bypass air inlet 1091 can also be located on other surfaces of the second space 1052 and indirectly connected to the third space 1053 through pipes or other air duct structures, thereby allowing air to enter the third space 1053 from the second space 1052.

[0114] In some illustrative embodiments, reference is made to Figure 8As shown, the bypass air outlet 1092 is located on the opposite side of the bypass air inlet 1091 and connects the third space 1053 and the second space 1052, allowing air to enter the second space 1052 from the third space 1053. Specifically, similar to the bypass air inlet 1091, the bypass air outlet 1092 is also formed on and through the partition 1056 that isolates the second space 1052 and the third space 1053. Furthermore, the bypass air outlet 1092 is configured to be spaced apart from the bypass air inlet 1091 on the partition 1056, i.e., a certain distance is formed between them. It can be understood that in other embodiments, the bypass air outlet 1092 may also be located on other surfaces of the second space 1052 and indirectly connected to the third space 1053 through other air duct structures such as pipes, thereby allowing air to enter the second space 1052 from the third space 1053. Among them, a bypass air passage 109 is formed between the bypass air inlet 1091 and the bypass air outlet 1092, which allows air to circulate in the second space 1052 and the third space 1053.

[0115] According to an embodiment of the present invention, referring to Figure 8 As shown, the air handling unit 107 includes an odor generating module, which is suitable for emitting odor factors. For example, it can be used to enhance the fragrance of air flowing through the odor generating module.

[0116] Figure 9 yes Figure 7 A schematic diagram of the airflow direction in the third space of the air supply device shown.

[0117] In some illustrative embodiments, reference is made to Figure 8 and Figure 9 As shown, the air handling unit 107 is disposed between the bypass air inlet 1091 and the bypass air outlet 1092, and is located within the third space 1053. Specifically, the air handling unit 107 is configured to process air, specifically by treating air quality and other indicators through physical or chemical methods. In this embodiment, the air handling unit 107 includes an odor generating module capable of emitting odor factors. Furthermore, the bypass ventilation path 109 also includes a bypass air supply section 1071, which may specifically be a bypass motor, bypass fan blades, and a duct housing. This creates a pressure difference between the second space 1052 and the third space 1053, promoting air circulation within the bypass ventilation path 109. Furthermore, the air handling unit 107 also includes an inspection opening for removing the odor generating module, and an inspection cover covering the inspection opening. When the user opens the inspection cover, the odor generating module can be inspected or replaced, allowing the user to change or update the type of odor factor, providing a better user experience.

[0118] In some illustrative embodiments, reference is made to Figure 8 and Figure 9 As shown, the duct housing is used to accommodate bypass fan blades and includes an air inlet 1054, a first duct wall with the air inlet 1054, a second duct wall located opposite the first duct wall, and a duct sidewall connecting the first and second duct walls. One end of the first duct wall, the second duct wall, and the duct sidewall forms an air outlet 1011, which connects to a bypass air outlet 1092. Further, the bypass air supply section 1071 may, but is not limited to, be located upstream of the air handling unit 107. It is understood that in other embodiments, the bypass air supply section 1071 may also be located downstream of the air handling unit 107.

[0119] In this implementation, when the air supply device is running, air enters the second space 1052 from the air inlet 1054. Part of the air in the second space 1052 enters the snail shell under the action of the fan blades and is blown out towards the first space 1051. Part of the air in the second space 1052, under the action of the bypass air supply section 1071, enters the third space 1053 through the bypass air inlet 1091, and then, under the action of the bypass fan blades, enters the duct shell from the duct air inlet 1054. Guided by the duct shell, it is then blown out through the duct air outlet 1011. Since the air handling section 107 is located downstream of the bypass air supply section 1071, i.e., downstream of the duct air outlet 1011, the air blown out from the bypass air supply section 1071 flows through the air handling section 107, is processed by the air handling section 107, and is then blown towards the bypass air outlet 1092 and out towards the second space 1052.

[0120] When air in the bypass ventilation duct 109 flows through the air handling unit 107, it carries away the emitted odor factors, such as fragrances or odor factors that can enhance concentration, after passing through the odor generating module (i.e., the air handling unit 107). The air carrying the odor factors is then blown out again into the second space 1052 through the bypass air outlet 1092 and enters the main air duct, where it is blown towards the user through the air outlet 1011, thereby allowing the user to experience the fragrant or concentration-enhancing air, thus improving the user's comfort or concentration.

[0121] Based on this, since the bypass air outlet 1092 is located on the opposite side of the bypass air inlet 1091 and is a certain distance away from the bypass air inlet 1091, it can suppress the air blown out from the bypass air outlet 1092 from being sucked in again through the bypass air inlet 1091 to a certain extent, thereby suppressing turbulence.

[0122] Furthermore, since the bypass air outlet 1092 is connected to the second space 1052, and the air pressure in the second space 1052 is lower than that in the first space 1051, it can suppress the situation where air cannot be blown out due to the air pressure difference when the bypass air outlet 1092 is connected to the first space 1051.

[0123] Furthermore, when users only need the air supply function and not air treatment functions such as fragrance, they can turn off the bypass air supply unit 1071 independently. Since the bypass air outlet 1092 connects to the second space 1052 instead of the first space 1051, when the bypass air supply unit 1071 is closed, air will not enter the third space 1053 from the bypass air outlet 1092 due to air pressure difference, thus providing users with a more personalized user experience.

[0124] Third Embodiment

[0125] The third embodiment of this utility model will be described below, and the parts that are the same as those in the first and second embodiments will not be repeated.

[0126] In some illustrative embodiments, the air supply device includes a third space 1053, a bypass air passage 109 connecting a bypass air inlet 1091 and a bypass air outlet 1092, and an air handling unit 107. The air handling unit 107 is disposed in the bypass air passage 109, within the third space 1053, and located between the bypass air inlet 1091 and the bypass air outlet 1092. The air handling unit 107 is used to process air, specifically, including but not limited to processing air quality and other indicators through physical or chemical methods. In this embodiment, the air handling unit 107 includes an odor generating module capable of emitting odor factors. In other embodiments, the air handling unit 107 may also include an ionization module for ionizing air, etc.

[0127] The supplementary air inlet 1054 of the third space 1053 allows air from outside the housing 105 to enter the third space 1053 and is connected to the bypass ventilation duct 109. Specifically, the supplementary air inlet 1054 is provided on the bypass ventilation duct 109 and is located upstream of the air handling unit 107.

[0128] In this implementation, it can be understood that the bypass air supply section 1071 in the second embodiment is replaced by the supplementary air inlet 1054. That is, under the action of the air supply section 200, the air pressure in the second space 1052 is lower than the air pressure in the first space 1051 and the third space 1053. At this time, air from the external space outside the housing 105 is drawn into the third space 1053 through the supplementary air inlet 1054, mixes with the air entering through the bypass air inlet 1091, flows through the air handling section 107, and is then blown back into the second space 1052 through the bypass air outlet 1092. Therefore, even without the bypass air supply section 1071 in the third space 1053, air can smoothly enter the third space 1053 and be blown out again into the second space 1052. This reduces the manufacturing and usage costs of the air supply device.

[0129] The embodiments of this utility model have now been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of this utility model.

[0130] It should be noted that implementations not shown or described in the accompanying drawings or the main text of the specification are all forms known to those skilled in the art and are not described in detail. Furthermore, the definitions of the components described above are not limited to the specific structures and shapes mentioned in the embodiments, and those skilled in the art can easily modify or substitute them.

[0131] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
