Description

Technical Field

[0001] The present invention relates to the field of air conditioning, and more particularly to a fan. Background Art

[0002] Most of the existing bladeless fans operate in a mode of low air intake and upward air blowing. Air is sucked in from the bottom by a vertical motor at the bottom of the bladeless fan, and a vertical air flow is generated by the vertical motor. After being delivered to a nozzle above the vertical motor, the air flow is guided to the horizontal direction and ejected from the nozzle.

[0003] The following technical problems exist in this structure:

[0004] 1. The position of air intake is relatively low, which easily sucks dust on the ground or tabletop, thus reducing the air quality and shortening the service life of the air purifier in the fan.

[0005] 2. The filter of the traditional bladeless fan is set at the lower part. Taking the scenario of the fan being placed on the ground as an example, every time the filter is replaced, the user needs to disassemble the shell and bend down to take out the old filter, and then bend down again to install the new filter, resulting in poor user experience. Especially for the elderly to replace the filter, there are potential safety hazards.

[0006] 3. In order to achieve the effect of high - altitude air outlet, the height of the nozzle is simply increased in the existing products. However, the farther the vertical distance that the vertical motor at the bottom transports the air flow, the smaller the wind force. This causes a large air volume at the lower part of the nozzle blowing and a small air volume at the upper part, which is completely opposite to the purpose of the vertical fan mainly blowing air to the upper body of the human body. Therefore, the traditional bladeless fans and related improved products cannot replace the effect of the vertical fan.

[0007] Therefore, the present invention provides a fan. Summary of the Invention

[0049] Figure 1 A perspective view of the first perspective of the fan of the present invention. Figure 2 A perspective view of the second perspective of the fan of the present invention. Figure 3 A side cross-section of the fan of the present invention. As Figures 1 to 3 shown, the fan of the present invention includes: an integral part 1, a support member 41, a base 42, and a nozzle 7. The body part 1 includes an air inlet, an air outlet, and a fan motor assembly 5. The fan motor assembly 5 includes a horizontal motor for generating an air flow through the body part 1. The support member 41 supports the body part 1. The nozzle 7 is connected to the body part 1 based on the air outlet direction of the horizontal motor, and is used to receive the air flow from the body part, disperse it inside the nozzle 7 to each air outlet 71 and eject it. The base 42 supports the support member 41. The support member 41 is a support rod, and the extending direction of the support rod is perpendicular to the rotation axis of the horizontal motor. The opening direction of the air outlet 71 is parallel to the rotation axis of the horizontal motor. The outer shell of the body part 1 is a horizontally arranged cylindrical shell, and the cylindrical shell sleeves the horizontal motor, and the shell is provided with a plurality of air inlet holes 11. The cylindrical shell includes a first end and a second end opposite to each other. The first end of the cylindrical shell communicates with a wind guide cover 6, and the wind guide cover 6 guides the air flow to the bottom 7A of the nozzle 7. The air flow moves along the internal annular air passage of the annular nozzle in the anti-gravity direction to the top 7B of the nozzle 7, and is sequentially dispersed to each air outlet 71 and then ejected respectively. The second end of the cylindrical shell is provided with a detachable cover plate. The present invention provides a bladeless fan mainly used in the use scenario of a floor fan, which completely replaces the traditional floor fan, expands the use scenario, and improves the user experience.

[0050] In a preferred example, the support rod is a liftable support tube assembly, and the support tube assembly includes an inner tube and an outer tube that axially move and limit each other, so that the vertical height of the fan air outlet can be freely adjusted.

[0051] Figure 4 A schematic diagram of the movement direction of the air flow of the fan of the present invention in the wind guide cover and the nozzle. Refer to Figure 3 and 4As shown, the nozzle 7 is a hollow annular nozzle, and a plurality of air outlets 71 are distributed on the side of the annular nozzle facing away from the body portion 1 along the extension direction of the inner cavity of the annular nozzle. In a preferred example, the cross-sectional area of the internal pipeline of the nozzle 7 gradually decreases as the position changes from the bottom 7A to the top 7B of the nozzle 7, so as to achieve the effect of distal pressurization, but not limited thereto.

[0052] The air guide cover 6 in this embodiment at least includes: a first drainage slope 61, a wind dividing wall 62, a second drainage slope 63, and a third drainage slope 64. Among them, the first drainage slope 61 is a sloped surface that guides the air flow generated by the fan motor assembly 5 to deflect downward by 70° to 85° from the horizontal direction (preferably guiding the air flow to deflect downward by 80° from the horizontal direction). The air outlet direction of the horizontal motor is perpendicular to the movement direction of the air flow in the inner cavity of the nozzle 7, but not limited thereto.

[0053] The wind dividing wall 62 is embedded within the range of the internal pipeline of the nozzle 7 and continues after the first drainage slope 61. The wind dividing wall 62 is configured to be vertically arranged, and arc-shaped second drainage slopes 63 and third drainage slopes 64 are respectively formed on the left and right sides of the wind dividing wall 62, extending in an arc shape to the left and right sides. The wind dividing wall 62 divides the air flow introduced into the first drainage slope 61 into a first air branch and a second air branch from left to right. Among them, the first air branch enters the internal pipeline on the left side of the nozzle 7, moves along the clockwise direction to the top 7B of the nozzle 7 (clockwise upward), and is ejected after reaching each air outlet 71 on the left side of the nozzle 7; similarly, the second air branch enters the internal pipeline on the right side of the nozzle 7, moves along the counterclockwise direction to the top 7B of the nozzle 7 (counterclockwise upward), and is ejected after reaching each air outlet 71 on the right side of the nozzle 7, but not limited thereto.

[0054] In this embodiment, the first drainage slope 61, the wind dividing wall 62, the second drainage slope 63, and the third drainage slope 64 are realized by the surfaces of different parts of the same diversion structure, but not limited thereto. The present invention realizes the smooth diversion of the linear air flow to different air outlets 71 of the nozzle 7 through the air guide cover 6 and the nozzle 7, thereby reducing noise, avoiding the reduction of wind pressure during the adjustment of the air flow direction, maintaining the air volume of the air flow, making the air volume of the air flow ejected from the nozzle 71 basically close to the air volume of the air flow generated by the fan motor assembly 5, and minimizing the loss of wind force by the internal pipeline.

[0055] Figure 5 It is a schematic diagram of the air outlet distribution of the nozzle of the fan of the present invention. As Figure 5As shown, the flow cross-sectional area of each air outlet 71 gradually increases as the position changes from the bottom 7A to the top 7B of the nozzle 7. In this embodiment, by optimizing and adjusting the opening areas of the air outlets at different positions, the air volume of each air outlet 71 at different heights is made substantially equal, but this is not limiting. The air outlet 71 may also be a circular opening, an oval opening, etc., without being limited thereto.

[0056] In a preferred example, the air outlet 71 is a rectangular opening. As the air outlet 71 rises from the bottom 7A to the top 7B of the nozzle 7 based on the position of the nozzle 7, the length of the long side of the rectangular opening gradually increases, but this is not limiting.

[0057] In a preferred example, the air outlet 71 is a rectangular opening. As the air outlet 71 rises from the bottom 7A to the top 7B of the nozzle 7 based on the position of the nozzle 7, the length of the short side of the rectangular opening gradually increases, but this is not limiting.

[0058] Figure 6 This is a schematic diagram of replacing the filter of the fan of the present invention. As Figure 6 shown, an air intake hood 3 communicating with the fan motor assembly 5 is further provided in the body 1. The annular gap between the air intake hood 3 and the outer shell is filled with a tubular filter 2. The air intake hole 11 is located upstream of the tubular filter 2, and the tubular filter 2 is located upstream of the air intake hood 3. A detachable cover plate 12 is provided at the second end of the cylindrical outer shell. After removing the cover plate 12, the replaceable filter 2 is exposed. In this embodiment, the filter 2 is a tubular filter. An air intake hood 3 communicating with the fan motor assembly 5 is further provided in the body 1. An annular channel for inserting the tubular filter is formed in the annular gap between the air intake hood 3 and the outer shell. The central axis of the annular channel is parallel to the rotation axis of the horizontal motor. The annular channel is filled with the tubular filter 2. The air intake hole 11 is located upstream of the tubular filter 2, and the tubular filter 2 is located upstream of the air intake hood 3.

[0059] And, continuing to refer to Figure 6 , the internal filter 2 of the fan of the present invention can be replaced through the following steps:

[0060] S110. Remove the cover plate at the second end of the cylindrical outer shell to expose the filter to be replaced;

[0061] S120. Draw out the filter to be replaced along the direction parallel to the rotation axis of the horizontal motor;

[0062] S130. Insert another filter along the direction parallel to the rotation axis of the horizontal motor; and

[0063] S140. Install the cover plate back to the second end of the cylindrical outer shell.

[0064] In the present invention, the filter is located in the upper region of the whole machine, and users can replace the filter in an upright state without bending down, which reduces the physical effort of users and greatly optimizes the process of replacing the filter.

[0065] In summary, the purpose of the present invention is to provide a fan that can raise the position of sucking air, avoid indoor ground air from entering the fan, and can concentrate the wind force for high-position emission, completely replacing the traditional vertical fan, expanding the usage scenarios and enhancing the user experience.

[0066] The above content is a further detailed description of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or replacements can still be made, and all should be regarded as belonging to the protection scope of the present invention.
