Description

Technical Field

[0001] This application belongs to the field of fan technology, specifically relating to fans. Background Technology

[0002] Fan heaters are indispensable heating devices in winter. Most fan heaters on the market have a unidirectional airflow direction, but to cope with situations where multiple people need heating at the same time, some fan heaters with a circular airflow direction have also appeared on the market. However, the current fan heaters have a single airflow mode and cannot switch application scenarios. They can only cope with relatively simple heating scenarios and cannot effectively handle single-person heating or multiple-person heating at the same time. Summary of the Invention

[0003] In view of this, this application provides a fan, the fan including a housing assembly, a top cover assembly, and an air outlet mechanism, the air outlet mechanism being disposed inside one end of the housing assembly, and the top cover assembly being disposed at an opening at the other end of the housing assembly; the top cover assembly having a first air outlet, and the peripheral sidewall of the housing assembly having a second air outlet; wherein, when the fan is in a first state, the air generated by the air outlet mechanism can be blown out from the first air outlet, and when the fan is in a second state, the air generated by the air outlet mechanism can be blown out from the second air outlet.

[0004] The first air outlet is arranged in a ring shape so that air is blown out from all sides of the fan; the second air outlet is located on one side of the peripheral sidewall of the housing assembly so that air is blown out from one side of the fan.

[0005] The fan also includes a lifting mechanism, which is located inside the housing assembly and connected to the top cover assembly. The lifting mechanism can drive the top cover assembly to rise or fall in a direction close to or away from the air outlet mechanism, so that the fan can switch between the first state and the second state.

[0006] The first state is an ascending state, in which the air generated by the air outlet mechanism can be discharged from the first air outlet when the fan is in the ascending state; the second state is a descending state, in which the air generated by the air outlet mechanism can be discharged from the second air outlet when the fan is in the descending state.

[0007] When the fan is in the rising state, the lifting mechanism drives the top cover assembly to rise, and the lifting mechanism blocks the second air outlet, while the first air outlet is exposed. The air generated by the air outlet mechanism is blown out through the first air outlet. When the fan is in the falling state, the lifting mechanism drives the top cover assembly to fall, and the lifting mechanism exposes the second air outlet. The first air outlet is located inside the housing assembly, and the top cover assembly seals against at least a portion of the other end of the housing assembly. The air generated by the air outlet mechanism first passes through the first air outlet and then is blown out from the second air outlet.

[0008] When the fan is in the descending state, the top cover assembly seals against the portion of the other end of the housing assembly. The top cover assembly and the remaining portion of the other end of the housing assembly form a third air outlet, from which air can also be blown out. The third air outlet and the second air outlet are located on the same side of the housing assembly.

[0009] The other end of the housing assembly has a guide slope that faces the top cover assembly and is inclined upwards, so that air is blown out obliquely upwards from the third air outlet.

[0010] The housing assembly has an operating area, and the second air outlet is located on the same side of the housing assembly as the operating area.

[0011] When the fan is in the rising state, the direction of the air blown out from the first air outlet is divided into a first direction and a second direction. The first direction is opposite to the second direction, and the first direction is the same as the direction of the air blown out from the second air outlet. The air volume in the first direction is greater than the air volume in the second direction.

[0012] Specifically, when the fan is in the rising state or the falling state, the air volume of the first air outlet is different from that of the second air outlet.

[0013] The top cover assembly includes an annular air outlet grille, and the first air outlet is disposed on the annular air outlet grille. Along the radial direction of the annular air outlet grille, the first air outlet includes a first sub-air outlet and a second sub-air outlet. The first sub-air outlet is disposed further inward than the second sub-air outlet, and the area of ​​the first sub-air outlet is larger than the area of ​​the second sub-air outlet.

[0014] The housing assembly has a one-way air outlet grille at its second air outlet, and the inner wall of the one-way air outlet grille is inclined outward.

[0015] The fan provided in this application has two air outlets: a first air outlet and a second air outlet. When the fan is in the first state, the air generated by the air outlet mechanism can be blown out from the first air outlet, and the air can be blown out from the top cover assembly above. When the fan is in the second state, the air generated by the air outlet mechanism can be blown out from the second air outlet, and the air can be blown out from the side of the housing assembly. This allows for air to be blown out from different positions in different states, increasing the number of air outlet modes and realizing a dual air outlet mode. This allows for switching between application scenarios and dealing with diverse air blowing situations. Attached Figure Description

Detailed Implementation

[0029] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0030] In view of this, and to solve the above problems, this application provides a fan. Please refer to it as well. Figures 1-6 , Figure 1 This is a three-dimensional structural diagram of the fan in a first state according to one embodiment of this application. Figure 2 for Figure 1 The fan shown is a side view. Figure 3 for Figure 1 The diagram shows a three-dimensional cross-section of the fan. Figure 4 This is a three-dimensional structural diagram of the fan in the second state according to one embodiment of this application. Figure 5 for Figure 4 The fan shown is a side view. Figure 6 for Figure 4 The diagram shows a three-dimensional cross-sectional view of a fan. This embodiment provides a fan 1, which includes a housing assembly 10, a top cover assembly 20, and an air outlet mechanism 30. The air outlet mechanism 30 is disposed inside one end of the housing assembly 10, and the top cover assembly 20 is disposed at the opening at the other end of the housing assembly 10. The top cover assembly 20 is provided with a first air outlet 200, and the peripheral sidewall of the housing assembly 10 is provided with a second air outlet 100. When the fan 1 is in a first state, the air generated by the air outlet mechanism 30 can be blown out from the first air outlet 200, and when the fan 1 is in a second state, the air generated by the air outlet mechanism 30 can be blown out from the second air outlet 100.

[0031] Fan 1 is a device capable of blowing air outwards. In terms of usage scenarios, the fan 1 provided in this embodiment includes, but is not limited to, household fans and industrial fans. In terms of type, it includes, but is not limited to, table fans and standing fans. This embodiment only illustrates the use of a household table fan. The air blown out by fan 1 can be cold or hot air.

[0032] The fan 1 includes a housing assembly 10, a top cover assembly 20, and an air outlet mechanism 30. The housing assembly 10 forms the outer shell of the fan 1 and is arranged in a ring shape, forming an overall cylindrical structure. Most of the structural components of the fan 1 can be installed inside the housing assembly 10, which provides effective protection. Optionally, the housing assembly 10 includes a front shell 11 and a rear shell 12. The front shell 11 has an operation panel, and the rear shell 12 has an air inlet 120. Optionally, the fan 1 also includes a base 40, with one end of the housing assembly 10 along its height direction, i.e., the lower end, mounted on the base 40.

[0033] The air outlet mechanism 30 is the core component of the fan 1. When the air outlet mechanism 30 is working, it generates airflow, which is transmitted through the air guide channel within the housing assembly 10 and finally blown out from the air outlet. Simultaneously, external airflow enters the housing assembly 10 through the air inlet 120 of the rear housing 12. Optionally, the air outlet mechanism 30 may include, but is not limited to, a centrifugal fan, an inertial flow fan, or an axial flow fan. The air outlet mechanism 30 is disposed within the housing assembly 10 and located at one end of the housing assembly 10, i.e., the lower end. The air outlet mechanism 30 may also be disposed on the base 40 below, and the airflow generated by the air outlet mechanism 30 is blown out towards the other end of the housing assembly 10, i.e., the upper end, so that the airflow is transmitted from one end of the housing assembly 10 to the other end; in other words, the airflow is transmitted from bottom to top.

[0034] The top cover assembly 20 is a component at the top of the fan 1, mainly used to achieve top air outlet. The top cover assembly 20 is located at the opening at the other end of the housing assembly 10, i.e., the upper end of the housing assembly 10, and is disposed opposite to the air outlet mechanism 30. The top cover assembly 20 may be provided with a first air outlet 200 communicating with the internal air duct. The structure of the first air outlet 200 is not limited in this embodiment. A second air outlet 100 may be provided on the peripheral side wall of the housing assembly 10, i.e., on the side of the housing assembly 10. The structure of the second air outlet 100 is not limited in this embodiment.

[0035] In summary, this embodiment provides two air outlets: a first air outlet 200 and a second air outlet 100. When the fan 1 is in the first state, the air generated by the air outlet mechanism 30 can be blown out from the first air outlet 200 (e.g., Figure 2 (As indicated by the black arrow), at this time, air can be blown out from the top cover assembly 20 above. When the fan 1 is in the second state, the air generated by the air outlet mechanism 30 can be blown out from the second air outlet 100 (as shown by the black arrow). Figure 5(As indicated by the black arrow), air can be blown out from the side of the housing assembly 10, thus enabling air to exit from different positions in different states, increasing the number of air outlet modes, achieving dual air outlet modes, and allowing switching between application scenarios to cope with diverse air blowing situations. It is worth noting that the first state and the second state of fan 1 are two different states, and the specific state is not limited in this embodiment.

[0036] Optionally, the fan 1 also includes a heating element, which is located on one side of the air outlet mechanism 30. In other words, the heating element is located on the necessary path of the air duct. When the heating element is working, it will generate heat, which can increase the temperature of the air and make the blowing air warm or hot. In this case, the fan 1 can also be called a heater.

[0037] Please refer to this again. Figures 1-2 ,as well as Figure 5 In this embodiment, the first air outlet 200 is arranged in a ring shape so that air is blown out from all sides of the fan 1; the second air outlet 100 is located on one side of the periphery of the housing assembly 10 so that air is blown out from one side of the fan 1.

[0038] In this embodiment, a first air outlet 200 is provided around the top cover assembly 20. In other words, the first air outlet 200 is arranged in a 360° pattern. Therefore, when air blows out from the first air outlet 200, the air can be discharged in all directions in a 360° manner, achieving ring-shaped airflow, so that people around the fan 1 can feel the airflow. The second air outlet 100 is only provided on one side of the side wall of the housing assembly 10. Therefore, when air blows out from the second air outlet 100, the air blows only in one direction, achieving unidirectional airflow and increasing the airflow in a certain direction. Therefore, this embodiment can realize the switching between ring-shaped airflow mode and unidirectional airflow mode, which can well cope with scenarios of single-person heating and multiple people heating at the same time.

[0039] In addition, this application uses two different air outlets for different air outlet modes. A second air outlet 100 is opened on the housing component 10 for unidirectional air outlet. Compared with the technical solution of partially blocking the annular air outlet to achieve unidirectional air outlet, this application has a faster wind speed and a more concentrated airflow organization, giving users a better unidirectional air outlet experience.

[0040] Of course, in other embodiments, the first air outlet 200 can be a unidirectional air outlet and the second air outlet 100 can be a ring-shaped air outlet.

[0041] Please refer to this again. Figure 2 and Figure 6In this embodiment, the fan 1 further includes a lifting mechanism 50, which is disposed inside the housing assembly 10 and connected to the top cover assembly 20. The lifting mechanism 50 can drive the top cover assembly 20 to rise or fall in a direction close to or away from the air outlet mechanism 30, so that the fan 1 can switch between the first state and the second state.

[0042] In addition to the aforementioned components, the fan 1 may also include a lifting mechanism 50. The lifting mechanism 50 may also be located inside the housing assembly 10. The lifting mechanism 50 is positioned above the air outlet mechanism 30 and connected to the uppermost top cover assembly 20. The lifting mechanism 50 primarily functions to raise and lower the fan. Therefore, the lifting mechanism 50 can drive the top cover assembly 20 to descend in the direction closer to the air outlet mechanism 30 or rise in the direction farther away from the air outlet mechanism 30.

[0043] Therefore, in this embodiment, the lifting mechanism 50 controls the top cover assembly 20 to rise or fall, thereby switching the fan 1 between a first state and a second state. Simultaneously, the lifting mechanism 50 and the top cover assembly 20 can change the airflow during the lifting process, thus achieving switching between a circular airflow mode and a unidirectional airflow mode.

[0044] In this embodiment, the first state is an ascending state, when the fan 1 is in the ascending state, the air generated by the air outlet mechanism 30 can be discharged from the first air outlet 200; the second state is a descending state, when the fan 1 is in the descending state, the air generated by the air outlet mechanism 30 can be discharged from the second air outlet 100.

[0045] When the first state is the rising state, the air generated by the air outlet mechanism 30 will exit from the first air outlet 200 of the top cover assembly 20. When the second state is the falling state, the air generated by the air outlet mechanism 30 can exit from the second air outlet 100 on the side of the housing assembly 10. For example, when the first air outlet 200 is arranged in a ring and the second air outlet 100 is arranged in a unidirectional manner, it is possible to achieve a simple structure and a simplified air duct design by controlling the ring air outlet in the rising state and the unidirectional air outlet in the falling state, making it easier to implement. Of course, in other embodiments, the first air outlet 200 can be arranged in a unidirectional manner and the second air outlet 100 in a ring manner, so that the air outlet in the rising state is unidirectional and the air outlet in the falling state is ring. This embodiment and the following text are only used to illustrate the ring air outlet in the rising state and the unidirectional air outlet in the falling state.

[0046] In this embodiment, when the fan 1 is in the rising state, the lifting mechanism 50 drives the top cover assembly 20 to rise, and the lifting mechanism 50 blocks the second air outlet 100, while the first air outlet 200 is exposed. The air generated by the air outlet mechanism 30 is blown out through the first air outlet 200. When the fan 1 is in the falling state, the lifting mechanism 50 drives the top cover assembly 20 to fall, and the lifting mechanism 50 exposes the second air outlet 100. The first air outlet 200 is located inside the housing assembly 10, and the top cover assembly 20 seals against at least a portion of the other end of the housing assembly 10. The air generated by the air outlet mechanism 30 first passes through the first air outlet 200 and then is blown out from the second air outlet 100.

[0047] Specifically, the air duct inside the housing assembly 10 can connect the first air outlet 200 and the second air outlet 100. When the fan 1 is in the rising state, the lifting mechanism 50 will drive the top cover assembly 20 to rise. At this time, the lifting mechanism 50 blocks the second air outlet 100, so the air cannot be blown out from the second air outlet 100. At the same time, since the top cover assembly 20 rises and exposes the first air outlet 200, the air generated by the air outlet mechanism 30 can only be blown out in all directions through the first air outlet 200.

[0048] Conversely, when fan 1 is in the descending state, the lifting mechanism 50 drives the top cover assembly 20 to descend, and the lifting mechanism 50 exposes the second air outlet 100. At this time, the air should be blown outward from both the first air outlet 200 and the second air outlet 100 simultaneously. However, when the top cover assembly 20 descends, not only does it place the first air outlet 200 inside the housing assembly 10, preventing the air blown out from the first air outlet 200 from reaching the outside, but the top cover assembly 20 also seals at least part of the other end of the housing assembly 10, sealing the opening at the upper end of the housing assembly 10. At this time, the air generated by the air outlet mechanism 30 first passes through the first air outlet 200, and can only be blown out unidirectionally from the second air outlet 100, either entirely or mostly.

[0049] In summary, this embodiment achieves the switching between the first air outlet 200 and the second air outlet 100 without the need for additional mechanisms and components through the cooperation of the lifting mechanism 50 and the top cover assembly 20, thus simplifying the internal structure of the fan 1.

[0050] It is worth noting that when the fan 1 is in the lowered state, the top cover assembly 20 can seal against the entire other end of the housing assembly 10. In this case, the air blown from the first air outlet 200 cannot exit through the opening of the upper housing assembly 10, and therefore the air can only exit from the second air outlet 100. Alternatively, the top cover assembly 20 can seal against a portion or part of the other end of the housing assembly 10. In this case, some of the air blown from the first air outlet 200 can exit from the unsealed contact point between the top cover assembly 20 and the other end of the housing assembly 10, while some air still exits unidirectionally from the second air outlet 100. This embodiment is only illustrated by the example of the top cover assembly 20 sealing against a portion or part of the other end of the housing assembly 10.

[0051] Please refer to this as well. Figures 7-8 , Figure 7 This is a three-dimensional structural diagram of the lifting mechanism and the top cover assembly in one embodiment of this application. Figure 8 for Figure 7 The diagram shows an exploded view of the lifting mechanism and the top cover assembly. In this embodiment, the lifting mechanism 50 includes a fixed base 51, a rotating component 52, and a lifting component 53. The rotating component 52 is rotatable relative to the fixed base 51. The rotating component 52 has an inclined slide groove 520. The lifting component 53 includes a lifting member 530, one end of which is disposed within the slide groove 520. When the rotating component 52 rotates relative to the fixed base 51, the rotating component 52 can drive the lifting component 53 to descend or ascend in a direction closer to or farther from the fixed base 51 via the lifting member 530.

[0052] The fixed base 51 is usually fixed to other components, so the fixed base 51 remains stationary. The rotating component 52 can rotate relative to the fixed base 51. For example, the lifting mechanism 50 also includes a drive component 54, which is rotatably connected to the rotating component 52. The drive component 54 provides the rotating component 52 with the power to rotate relative to the fixed base 51. When the drive component 54 is working, it can drive the rotating component 52 to rotate relative to the fixed base 51.

[0053] Optionally, the inner side of the rotating member 521 has a gear ring, and the driving assembly 54 includes a driving member and a gear member. The power output shaft of the driving member is connected to the gear member. When the driving member is turned on, it drives the gear member to rotate. The gear member meshes with the gear ring to drive the rotating member 521 to rotate relative to the fixed base 51.

[0054] In this embodiment, the transmission method employing gears meshing with a gear ring ensures stable power transmission and precise transmission ratio, avoiding slippage and free rotation. This allows for adjustable rotation angle and speed of the rotating component 521 relative to the fixed base 51, thereby achieving precise control over the lifting position of the lifting assembly 53. Simultaneously, the gear ring is located inside the rotating component 521, fully utilizing the internal space, resulting in a more compact overall structure, smaller footprint, and easier assembly of the lifting mechanism 50, thus improving its performance.

[0055] The rotating assembly 52 has an inclined slide 520. Understandably, when the fan 1 is supported on the ground or a table waiting for support, the slide 520 is inclined relative to the horizontal direction, and / or the slide 520 is inclined relative to the direction of gravity.

[0056] The lifting assembly 53 includes a lifting member 530, one end of which is movably disposed within a slide groove 520, meaning the relative position of the lifting member 530 and the rotating assembly 52 is adjustable. More specifically, one end of the lifting member 530 can slide along the extending direction of the slide groove 520. Understandably, the lifting assembly 53 has a raised state and a lowered state relative to the fixed seat 51. When the lifting assembly 53 is in the raised state, it moves away from the fixed seat 51; when the lifting assembly 53 is in the lowered state, it moves closer to the fixed seat 51.

[0057] When the drive assembly 54 drives the rotating assembly 52 to rotate relative to the fixed base 51, the side wall of the slide groove 520 of the rotating assembly 52 applies a thrust along the extension direction of the slide groove 520 to the lifting member 530, thereby causing one end of the lifting member 530 to move relative to the slide groove 520 along the extension direction of the slide groove 520. The thrust provided by the rotating assembly 52 to the lifting member 530 can be decomposed into a horizontal component and a vertical component. The horizontal component is canceled or constrained by the limiting structure of the fixed base 51, and the vertical component can drive the lifting member 530 to move towards or away from the fixed base 51, so that the lifting member 530 descends or rises along the height direction, thereby driving the lifting assembly 53 to rise and fall smoothly. This embodiment, by setting an inclined slide groove 520 and lifting member 530 cooperation structure, can efficiently convert the rotational motion of the rotating assembly 52 into the linear lifting motion of the lifting assembly 53, without the need for complex transmission components such as connecting rods and lead screws, making the overall structure simpler and more compact. Meanwhile, through the rotational drive and the guiding mechanism of the inclined slide 520, the lifting component 53 experiences uniform force, smooth transmission, and is less prone to jamming during its lifting motion. This ensures stable movement and accurate positioning of the lifting component 53 during ascent and descent, improving the operational reliability and service life of the lifting mechanism 50. When the lifting mechanism 50 is applied to the fan 1, it can precisely adjust the relative height between the lifting component 53 and other components within the fan 1, thereby enabling smooth switching between different airflow modes. This meets the fan 1's requirements for efficient, stable, and low-noise airflow mode switching, enhancing the performance of the fan 1.

[0058] Understandably, during this process, the lifting component 530 does not rotate relative to the fixed seat 51. By restricting the lifting component 530 to only perform linear lifting motion and preventing it from rotating circumferentially with the rotating component 52, rotational deviation, swaying, or jamming of the lifting component 53 during lifting can be avoided, making the lifting motion of the lifting component 53 smoother and the positioning more precise. At the same time, it can prevent interference and wear between the lifting component 530 and the surrounding structure, significantly improving the operational stability, reliability, and service life of the lifting mechanism 50, and effectively reducing operating noise.

[0059] In addition, the lifting component 530 is connected to the top cover assembly 20. When the fan 1 is in the rising state, the lifting component 530 rises and blocks the second air outlet 100. When the fan 1 is in the falling state, the lifting component 530 falls to expose the second air outlet 100.

[0060] In this embodiment, the fixing base 51 includes a fixed side portion 511 and a fixed bottom portion 512 that are bent and connected together. The fixed side portion 511 is arranged around the outer periphery of the rotating assembly 52, and the fixed bottom portion 512 extends inward. The rotating assembly 52 is supported on the fixed bottom portion 512. The rotating assembly 52 includes a rotating member 521 and a connecting member 522. The rotating member 521 is rotatably connected to the fixing base 51, and the connecting member 522 connects to the side of the rotating member 521 that is away from the fixed bottom portion 512. The connecting member 522 has the sliding groove 520.

[0061] The fixed side 511 has an annular structure and is disposed around the outer periphery of the rotating assembly 52. ​​The fixed bottom 512 is bent and connected to the fixed side 511, and the fixed bottom 512 extends inward; in other words, the fixed bottom 512 extends towards the center of the annular structure. Understandably, the rotating assembly 52 is disposed within the fixed base 51.

[0062] In this embodiment, the fixed base 51 includes a fixed side portion 511 and a fixed bottom portion 512 that are bent and connected together. The fixed side portion 511 is arranged around the outer periphery of the rotating component 52, so the fixed side portion 511 can circumferentially limit and protect the rotating component 52 to prevent the rotating component 52 from radially shifting, shaking, or falling out. At the same time, the rotating component 52 is supported by the fixed bottom portion 512, which can provide a stable support surface for the rotating component 52, so that the rotating component 52 is subjected to uniform force during rotation. The fixed side portion 511 and the fixed bottom portion 512 cooperate with each other to form a ring-shaped support structure, which provides stable axial support and circumferential limitation for the rotating component 52, improves the rotational stability of the rotating component 52 relative to the fixed base 51, and thus improves the operational stability of the lifting mechanism 50.

[0063] In addition, the rotating assembly 52 includes a rotating member 521 and a connecting member 522. The connecting member 522 is located on the side of the rotating member 521 away from the fixed bottom 512, which can make the mating position of the slide 520 and the lifting member 530 far away from the support area of ​​the fixed bottom 512. Thus, during the movement of the lifting member 530 along the slide 520, interference, friction or jamming between the lifting member 530 and the fixed seat 51, the rotating member 521 or other surrounding structures can be effectively avoided, ensuring that the lifting assembly 53's lifting movement is smoother and more stable.

[0064] In this embodiment, the fixed side 511 has a guide groove 510, the extension direction of the guide groove 510 is parallel to the lifting direction of the lifting assembly 53, one end of the lifting member 530 is disposed in the guide groove 510, and one end of the lifting member 530 passes through the slide groove 520 and the guide groove 510 in sequence.

[0065] In this embodiment, a guide groove 510 can be provided on the fixed side 511. The extension direction of the guide groove 510 is parallel to the lifting direction of the lifting component 53. When the fan 1 is supported on the ground or a table waiting for support, the guide groove 510 extends along the direction of gravity. When one end of the lifting component 530 is located in the guide groove 510, the guide groove 510 can form a reliable linear guide and circumferential limit constraint for the lifting component 530. This ensures that the lifting component 530 only moves in a straight line in the height direction without circumferential rotation or radial swaying. At the same time, it can counteract the horizontal component force generated by the inclined slide 520 during the movement, avoiding the lifting component 530 from deflection, swaying, and jamming. This makes the lifting motion of the lifting component 53 more straight, stable, and accurately positioned. In conjunction with the inclined slide 520, it stably converts the rotational motion of the rotating component 52 into the linear lifting motion of the lifting component 53, improving the overall operational stability and reliability of the lifting mechanism 50.

[0066] Please refer to this again. Figure 6 In this embodiment, when the fan 1 is in the descending state, the top cover assembly 20 seals against the portion of the other end of the housing assembly 10, and the top cover assembly 20 and the remaining portion of the other end of the housing assembly 10 form a third air outlet 23, from which air can also be blown out, and the third air outlet 23 and the second air outlet 100 are located on the same side of the housing assembly 10.

[0067] As can be seen from the above, when the fan 1 is in the lowered state, the top cover assembly 20 can seal against a portion or part of the other end of the housing assembly 10, while the remaining portion of the top cover assembly 20 and the other end of the housing assembly 10 are not tightly abutted together, leaving a certain gap. At this time, the top cover assembly 20 and the housing assembly 10 can form a third air outlet 23. After the air generated by the air outlet mechanism 30 is blown out from the first air outlet 200, part of the air is still blown out from the second air outlet 100, and part of the air is blown out from the third air outlet 23. Since the top cover assembly 20 seals against a portion of the other end of the housing assembly 10, the top cover assembly 20 only forms the third air outlet 23 with a small portion of the other end of the housing assembly 10. At this time, the third air outlet 23 can also be understood as a one-way air outlet. Therefore, in this embodiment, an additional one-way air outlet can be added when the fan 1 is in the lowered state.

[0068] Furthermore, in this embodiment, based on the third air outlet 23, the third air outlet 23 and the second air outlet 100 can be located on the same side of the housing assembly 10. In other words, the air outlet direction from the second air outlet 100 is the same as or approximately the same as the air outlet direction from the second air outlet 100. This increases the air volume of unidirectional airflow.

[0069] Please refer to this as well. Figure 6 and Figure 9 , Figure 9 for Figure 1 The diagram shows a partial view of the fan from another perspective. In this embodiment, the other end of the housing assembly 10 has a guide slope 13 that faces the top cover assembly 20 and is inclined upwards, so that air is blown out obliquely upwards from the third air outlet 23.

[0070] As can be seen from the above, the top cover assembly 20 only seals against the other end of the housing assembly 10. The part of the other end of the housing assembly 10 that does not abut against the top cover assembly 20 has a surface facing the top cover assembly 20, i.e., the upper surface. In this embodiment, this surface can be inclined upward. At this time, this surface can also be called the guide slope 13. When some air is blown out from the third air outlet 23, due to the guiding effect of the inclined guide slope 13, the air can be blown out from the third air outlet 23 at an angle upward.

[0071] Therefore, this embodiment can optimize airflow organization by adding an extra unidirectional air outlet, ensuring that a certain amount of airflow can blow upwards at an angle, resulting in a better user experience. This avoids the situation where simple side blowing causes the airflow to blow downwards at an angle, failing to reach the user's designated area and reducing the user experience.

[0072] Please refer to this again. Figure 1 In this embodiment, the housing assembly 10 has an operation area 14, and the second air outlet 100 and the operation area 14 are located on the same side of the housing assembly 10.

[0073] An operation area 14 may be provided on one side of the housing assembly 10. An operation panel is provided within the operation area 14, allowing the user to perform various operations, such as turning the machine on and off, controlling the fan 1 to rise and fall, adjusting the airflow, and setting a timer. The operation area 14 typically needs to face the user directly for easy operation. In this embodiment, the second air outlet 100 and the operation area 14 are located on the same side of the housing assembly 10, allowing the air blown from the second air outlet 100 to directly reach the user.

[0074] Optionally, when the fan 1 is in the descending state, if the fan 1 also has a third air outlet 23, the third air outlet 23 and the operation area 14 are also located on the same side of the housing assembly 10, so that the second air outlet 100, the third air outlet 23 and the operation area 14 are arranged on the same side, so that the air blown out by the second air outlet 100 and the third air outlet 23 blows directly to the user.

[0075] Please refer to this again. Figure 2 In this embodiment, when the fan 1 is in the rising state, the direction of the air blown out from the first air outlet 200 is divided into a first direction (e.g., Figure 2 (as shown in D1) and the second direction (as shown in D1) Figure 2As shown in D2), the first direction is opposite to the second direction, and the first direction is the same as the direction of the air blown out from the second air outlet 100; wherein, the air volume in the first direction is greater than the air volume in the second direction.

[0076] When fan 1 is in the rising state, the second air outlet 100 is blocked by the lifting mechanism 50, while the first air outlet 200 rises and is exposed along with the top cover assembly 20. Therefore, air can be discharged in an annular pattern from the first air outlet 200. Based on the annular air discharge, this embodiment can further divide the direction of the air blown from the first air outlet 200 into two directions: a first direction and a second direction. The first direction is opposite to the second direction, and the first direction is the same as the direction of the air blown from the second air outlet 100. In other words, the direction of air blowing from the first air outlet 200 on the same side as the second air outlet 100 is the first direction, and the direction opposite to the first direction is the second direction.

[0077] Since the second air outlet 100 usually faces the user, the air from the first direction will also blow directly on the user. In this embodiment, when the air is circumferentially vented, the air volume from the first direction can be greater than the air volume from the second direction. This allows for a larger air volume blowing directly on the user side, thereby improving the heat dissipation and heating effects.

[0078] Please refer to this as well. Figure 3 , Figure 6 ,as well as Figure 10 , Figure 10 for Figure 4 The diagram shows a partial three-dimensional structure of the fan after removing the top cover assembly. In this embodiment, the fan 1 further includes an air guide assembly 60, which is disposed within the housing assembly 10 and located on one side of the air outlet mechanism 30. The air guide assembly 60 includes an air guide plate 61, which is inclined to the arrangement direction of the air guide assembly 60 and the air outlet mechanism 30. The air guide plate 61 is used to guide the air blown out by the air outlet mechanism 30. When the fan 1 is in a descending state, the air is blown out towards the second air outlet 100.

[0079] In addition to the aforementioned components, the fan 1 may also include an air guide assembly 60. The air guide assembly 60 is located inside the housing assembly 10 and on one side of the air outlet mechanism 30, which can be understood as the air guide assembly 60 being located on the air outlet side of the air outlet mechanism 30. When the fan 1 is supported on the surface to be supported, the arrangement direction of the air guide assembly 60 and the air outlet mechanism 30 is the direction of gravity.

[0080] In this embodiment, the air guide plate 61 can be tilted relative to the arrangement direction of the air guide assembly 60 and the air outlet mechanism 30. For example, when the fan 1 is supported on the surface to be supported, the air guide plate 61 is tilted relative to the horizontal direction, and / or, the air guide plate 61 is tilted relative to the direction of gravity. Specifically, the air guide plate 61 can be tilted toward the direction of the second air outlet 100.

[0081] In this embodiment, the air guide assembly 60 is disposed on one side of the air outlet mechanism 30, and the air guide plate 61 is inclined to the arrangement direction of the air guide assembly 60 and the air outlet mechanism 30. When the air generated by the air outlet mechanism 30 passes through the air guide plate 61, on the one hand, the air guide plate 61 can regulate and guide the scattered airflow blown out by the air outlet mechanism 30, avoiding disorderly diffusion of airflow inside the housing assembly 10 and the generation of eddies and turbulence by impacting the housing, making the airflow in the duct more stable and smooth, and ensuring the air outlet efficiency of the fan 1. On the other hand, the inclined air guide plate 61 can follow the natural flow path of the airflow, reduce the impact and friction between the airflow and the housing assembly 10 and the internal structure, significantly reduce the flow resistance in the duct, avoid the airflow attenuation caused by excessive resistance, and thus improve the air outlet effect of the fan 1. By setting the inclined air guide plate 61, this application optimizes the internal duct structure of the fan 1, improves the airflow guiding performance, and makes the fan 1 have higher air outlet efficiency and better air outlet effect.

[0082] In addition, in this embodiment, when the fan 1 is in the descending state, the inclined air guide plate 61 is also used to precisely guide the airflow generated by the air outlet mechanism 30 to the second air outlet 100 of the housing assembly 10, and to concentrate the airflow to form directional airflow, thereby improving the local airflow intensity and heating effect, meeting the needs of single-person directional heating, and improving the airflow efficiency and stability of the fan 1. Furthermore, the airflow generated by the air outlet mechanism 30 is constrained and guided to the second air outlet 100, which can prevent the airflow from diffusing, flowing back or being ineffectively dissipated inside, reducing airflow loss, reducing flow resistance, making the airflow of the fan 1 more stable and the noise lower, and improving the performance of the fan 1.

[0083] In this embodiment, when the fan 1 is in the rising state, since the first air outlet 200 is arranged in a ring, the air will blow out from the first air outlet 200 to all directions. However, due to the presence of the air guide plate 61, the air guide plate 61 is used to guide the air blown out by the air outlet mechanism 30 to the first air outlet 200, and make the air volume blown out through the first air outlet 200 unevenly distributed in the circumferential direction, and make the air volume in the first direction greater than the air volume in the second direction.

[0084] When fan 1 is in the rising state, fan 1 emits air in a ring. However, even with the ring-shaped airflow, due to the presence of the air guide plate 61, the air guide plate 61 will direct more airflow to the first air outlet 200, which is the same as the second air outlet 100, i.e., the first direction mentioned above. The airflow in the second direction will become less, thus making the airflow in the first direction greater than the airflow in the second direction.

[0085] Optionally, the first direction is parallel to or almost parallel to the tilting direction of the air guide plate 61, or the angle between the first direction and the tilting direction of the air guide plate 61 is an acute angle.

[0086] In this embodiment, the air outlet includes a first air outlet 200, which is arranged in a ring shape. When the air guide plate 61 directs the air blown out by the air outlet mechanism 30 to the first air outlet 200, the air outlet coverage of the fan 1 can be expanded to achieve large-scale, multi-angle air outlet and heat diffusion, improve the overall heating uniformity of the space, thereby meeting the heating needs of multiple people, broadening the application scenarios of the fan 1, and improving the applicability of the fan 1. Furthermore, since the air guide plate 61 is tilted, when the air from the air outlet mechanism 30 passes through the air guide plate 61 and flows to the first air outlet 200, the air volume and velocity at different positions in the circumference are distributed differently. This results in the air blown out from the first air outlet 200 forming an air outlet state with uneven air volume and intensity zones in the circumference. That is, a strong air outlet zone with concentrated air volume and higher velocity is formed in a specific direction in the circumference, while a regular air outlet zone with moderate air volume and soft coverage is formed in other directions. This allows the fan 1 to meet the dual needs of uniform heating of a large area and localized enhanced heating. The fan 1 can flexibly adapt to scenarios where multiple people are heating at the same time, further improving the performance of the fan 1.

[0087] In this embodiment, there are multiple air guide plates 61, which are arranged at intervals along their thickness direction; each air guide plate 61 is bent along its thickness direction. It can be understood that the air guide plates 61 are bent along their thickness direction to form an arc-shaped structure.

[0088] In this embodiment, multiple air guide plates 61 are arranged at intervals along the thickness direction of the air guide plate 61. The multiple air guide plates 61 cooperate with each other to evenly divide the overall airflow generated by the air outlet mechanism 30 into multiple independent airflows, which are then transported to the air outlet under the guidance of the air guide plates 61, thereby improving the airflow guiding efficiency of the air guide assembly 60 and improving the airflow smoothness of the fan 1. Furthermore, each air guide plate 61 is bent along its thickness direction, which allows the airflow to pass through the air guide plate 61 along the bent structure and flow smoothly to the air outlet, avoiding the formation of eddies or noise due to the impact of the straight edge, and further enhancing the airflow effect and performance of the fan 1. In addition, the bent air guide plate 61 can increase its contact area with the airflow, which can significantly reduce the airflow impact and flow resistance when the airflow passes through the air guide plate 61, reduce airflow loss, improve the airflow guiding effect of the air guide plate 61, and thus improve the airflow efficiency of the fan 1.

[0089] In this embodiment, when the fan 1 is in the rising state or the falling state, the air volume of the first air outlet 200 is different from the air volume of the second air outlet 100.

[0090] When fan 1 is in the rising state, air is blown out from the first air outlet 200; when fan 1 is in the falling state, air is blown out from the second air outlet 100. This embodiment can control the air volume of the first air outlet 200 and the air volume of the second air outlet 100 to be different, thereby controlling the air volume of different air outlet modes and achieving more targeted air outlet.

[0091] For example, in one embodiment, the air volume of the first air outlet 200 can be greater than that of the second air outlet 100. In other words, the air volume of the annular air outlet can be greater than that of the unidirectional air outlet, because annular air outlets blow air in all directions, reducing the airflow in each direction. By increasing the air volume of the annular air outlet, the air volume in each direction can be made consistent with that of the second air outlet 100. In another embodiment, the air volume of the first air outlet 200 can be less than that of the second air outlet 100. In other words, the air volume of the annular air outlet can be less than that of the unidirectional air outlet, allowing the airflow in unidirectional air outlets to reach the user more quickly and powerfully, thus increasing the airflow when directly blowing on the user and achieving a stronger effect.

[0092] Please refer to this again. Figure 3 and Figure 9 In this embodiment, the top cover assembly 20 includes an annular air outlet grille 21, and the first air outlet 200 is disposed on the annular air outlet grille 21. Along the radial direction of the annular air outlet grille 21, the first air outlet 200 includes a first sub-air outlet 201 and a second sub-air outlet 202. The first sub-air outlet 201 is disposed further inward than the second sub-air outlet 202, and the area of ​​the first sub-air outlet 201 is larger than the area of ​​the second sub-air outlet 202.

[0093] The annular air outlet grille 21 is circular, matching the shape of the opening at the other end of the housing assembly 10. The annular air outlet grille 21 has multiple holes arranged in an array, which constitute the aforementioned first air outlet 200. These holes are arranged in a 360° circumferential pattern, allowing air to be blown outwards from the annular air outlet grille 21. Along the radial direction of the annular air outlet grille 21, the first air outlet 200 can be divided into a first sub-air outlet 201 and a second sub-air outlet 202, with the first sub-air outlet 201 positioned further inwards than the second sub-air outlet 202. Along the circumferential direction of the annular air outlet grille 21, the multiple first sub-air outlets 201 located in the inner ring are evenly distributed, and the multiple second sub-air outlets 202 located in the outer ring are evenly distributed. This embodiment allows the area of ​​the first sub-air outlet 201 to be larger than the area of ​​the second sub-air outlet 202. The area of ​​the first sub-air outlet 201 in the inner ring is larger, and the area of ​​the second sub-air outlet 202 in the outer ring is smaller, thereby preventing the user's fingers from being inserted into the fan 1 through the second sub-air outlet 202 in the outer ring.

[0094] Optionally, the top cover assembly 20 also includes a top cover 22, which is disposed above the annular air outlet grille 21. The surface of the top cover 22 facing the annular air outlet grille 21 is arc-shaped so that the air blown out from the annular air outlet grille 21 is guided by the arc-shaped surface and eventually blows out in a roughly horizontal manner, thereby better blowing towards the user.

[0095] Please refer to Figure 11 , Figure 11 for Figure 9 The diagram shows a partial view of the fan after some structural components have been removed. In this embodiment, a one-way air outlet grille 15 is provided at the second air outlet 100 of the housing assembly 10, and the inner wall of the one-way air outlet grille 15 is inclined outward.

[0096] The housing assembly 10 has a second air outlet 100 on its peripheral sidewall. In this embodiment, a one-way air outlet grille 15 may also be provided at the second air outlet 100, and the inner wall of the one-way air outlet grille 15 may be inclined outward, thereby increasing the air outlet area, reducing the air outlet speed, and preventing hot air from impacting the user at too high a speed and causing discomfort. In addition, the outwardly inclined inner wall can optimize the airflow direction and increase the user's heat-receiving area.
