Abstract
Description
Technical Field
[0001] This utility model relates to the field of tower fan technology, and in particular to a tower fan panel structure. Background Technology
[0002] Tower fans, also known as tower fans due to their slender and upright shape resembling a skyscraper, utilize aerodynamic principles. An internal cross-flow fan generates centrifugal airflow through air pressure, which is then distributed via a guide structure. Because tower fans deliver a uniform and gentle airflow, closely resembling natural wind, they are increasingly popular with consumers. However, some existing tower fans have their control panels mounted on the top cover. Due to the decorative grooves on the front and back covers, these grooves may obstruct or press against the control panels, causing them to not adhere properly and potentially lift up. Furthermore, prolonged pressure from the control panel springs can also cause the control panels to lift or degrade the adhesive backing. Utility Model Content
[0003] The main purpose of this utility model is to provide a tower fan panel structure that makes the panel connection stable and prevents the panel from warping.
[0004] To achieve the above objectives, this utility model proposes a tower fan panel structure, comprising:
[0005] A cover, wherein a plurality of first snap-fit portions are provided circumferentially on the bottom surface of the cover;
[0006] The panel has a central portion that is recessed to form a mounting portion corresponding to the face cover. The face cover is fitted into the mounting portion. The surface of the mounting portion has multiple through holes corresponding to the first snap-fit portion. The surface of the panel also has multiple pressing portions.
[0007] The upper cover is attached to the lower surface of the panel. The surface of the upper cover has a plurality of second snap-fit parts corresponding to the first snap-fit part. The first snap-fit part passes through the through hole and is snapped and fixed to the second snap-fit parts one by one.
[0008] A circuit board is disposed below the upper cover. The circuit board is vertically arranged with multiple button springs, each of which abuts against the corresponding pressing part of the upper cover.
[0009] In one possible implementation, the side of the top cover facing the button spring is provided with a plurality of limiting grooves, and the button spring extends into the limiting grooves and abuts against the bottom of the grooves.
[0010] In one possible implementation, screw holes are provided on the surfaces of the top cover and the mounting portion respectively for connecting and fixing screws.
[0011] In one possible implementation, both the mounting portion and the top cover have an observation port at their center, and the face cover can cover the observation port.
[0012] This utility model's technical solution employs circumferentially distributed buckles and slots for mechanical locking between the front cover and the top cover, ensuring a firm connection between the panel and the top cover. Combined with a rigid screw connection, this creates a robust external connection that directly counteracts external stresses that could cause the panel to lift. The internal top cover also acts as a force distribution intermediary, integrating the upward force of multiple discrete button springs on the circuit board into a uniform support surface, effectively preventing the panel from being partially lifted due to uneven spring force.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0022] Reference Figures 1 to 4 This utility model proposes a tower fan panel 2 structure, including a front cover 1, a panel 2, a top cover 3, and a circuit board 4. The bottom surface of the front cover 1 is provided with a plurality of first snap-fit portions 11. The central area of the panel 2 is recessed to form a mounting portion 21 corresponding to the front cover 1. The front cover 1 is fitted into the mounting portion 21. The surface of the mounting portion 21 is provided with a plurality of through holes 22 corresponding to the first snap-fit portions 11. The surface of the panel 2 is also provided with a plurality of pressing portions 23. The top cover 3 is fitted to the lower surface of the panel 2. The surface of the top cover 3 is provided with a plurality of second snap-fit portions 31 corresponding to the first snap-fit portions 11. The first snap-fit portions 11 pass through the through holes 22 and are snap-fitted and fixed to the second snap-fit portions 31 one by one. The circuit board 4 is disposed below the top cover 3. The circuit board 4 is vertically provided with a plurality of button springs 41. The button springs 41 abut against the positions of the pressing portions 23 of the top cover 3 one by one.
[0023] Understandably, the top cover 1 is the uppermost cover, with multiple first latching parts 11 (in this embodiment, snap-fits) arranged around its bottom edge. The panel 2 is the area with buttons, printed with indicators such as power switch, fan speed, and mode. The central area of the panel 2 is recessed to form a mounting part 21 for holding the top cover 1. Multiple through holes 22 are formed around the edge of the mounting part 21, through which the snap-fits on the top cover 1 can pass. The pressing parts 23 are multiple areas on the surface of the panel 2 that are designed to be pressed, serving as trigger points for the buttons.
[0024] The top cover 3 is located between the panel 2 and the circuit board 4, and fits tightly against the bottom surface of the panel 2. The surface of the top cover 3 has multiple second latching parts 31 corresponding to the latches; in this example, these are latching slots. The latches pass through the through holes 22 of the mounting part 21 of the panel 2 and connect with the latching slots, firmly clamping the panel 2 between the front cover 1 and the top cover 3, ensuring a very secure connection and preventing the panel 2 from being lifted away from the top cover 3 by external force. Furthermore, the top of the vertically upward-pointing button spring 41 abuts against the bottom surface of the top cover 3, not directly against the panel 2. If the multiple button springs 41 on the circuit board 4 directly abut against the back of the panel 2, it would be difficult to ensure that the spring force and height of all springs are completely consistent. This could cause a spring with greater force to partially lift the panel 2, resulting in unevenness or a slight warping of a corner. The top cover 3, as a rigid intermediate layer, integrates the forces of multiple springs into a uniform upward supporting force, which is then transmitted to the entire panel 2, preventing any single spring from deforming the panel 2 due to its individual force.
[0025] Circuit board 4 is located directly below the top cover 3 and is the electronic control part. Multiple button springs 41 are vertically mounted on circuit board 4. The tops of these springs are exactly abutting the corresponding pressing part 23 on the back of the top cover 3. When the user presses a pressing part 23 on the panel 2 with his / her finger, the panel 2 is pressed downward. The pressing part 23 presses the corresponding button spring 41 below the top cover 3. The button spring 41 is flattened, and its internal contacts make contact with the circuit on the circuit board 4, triggering the corresponding electrical signal. After the user releases his / her hand, the elasticity of the button spring 41 makes it return to its original shape, completing a button operation.
[0026] Traditional tower fan bodies 7 have a gap between the front and rear outer casings at the top. Sometimes, the edge of this gap catches or abuts against the button panel 2, preventing the panel 2 from fitting flat and causing it to warp, affecting aesthetics and feel. This embodiment addresses this by using a tight fit between the snaps on the front cover 1 and the slots on the top cover 3 to firmly lock the top cover 3 and the panel 2 together, forming a sturdy unit. This mechanical locking force resists external interference and pressure, ensuring the panel 2 remains flat and does not warp in any area.
[0027] Reference Figures 3 to 4 In one embodiment of this utility model, the side of the upper cover 3 facing the button spring 41 is provided with a plurality of limiting grooves 32, and the button spring 41 extends into the limiting groove 32 and abuts against the bottom of the groove.
[0028] Understandably, the button spring 41 may slip from its preset position when subjected to lateral force or long-term vibration. Once displaced, it cannot accurately align with the force point of the top cover 3, causing the button to malfunction, feel weak, or even become permanently stuck. The limiting groove 32 restricts each spring within a specified range. This ensures that the springs do not move radially when the tower fan vibrates or when the user presses the button at an angle, guaranteeing long-term functional stability.
[0029] Reference Figure 2 In one embodiment of this utility model, screw holes 5 are correspondingly provided on the surfaces of the top cover 3 and the mounting part 21 for connecting and fixing screws.
[0030] Understandably, since snap-fit connections are inherently elastic, while effectively preventing separation, there is still a risk of loosening or gaps due to long-term use, material creep caused by thermal cycling, or continuous uneven stress. Screws, on the other hand, provide a rigid mechanical connection. Through powerful tightening force, they firmly press the top cover 3 and panel 2 together, virtually eliminating the possibility of displacement in any direction. Screws also provide the strongest resistance to the upward lifting force exerted on panel 2, fundamentally solving the lifting problem and achieving a rigid connection.
[0031] Reference Figure 2In one embodiment of this utility model, both the mounting part 21 and the upper cover 3 have an observation port 6 at their center, and the face cover 1 can cover the observation port 6.
[0032] Understandably, the observation port 6 penetrates the center of the mounting portion 21 of the panel 2 and the top cover 3, and is covered from above by the faceplate 1, for observing the internal structure. The presence of the observation port 6 does not weaken the connection strength between the top cover 3 and the panel 2. The fasteners and screws used for fixing are arranged in the area around the observation port 6, ensuring the structural stability of the entire assembly and that the anti-tilting function is not affected in any way. At the same time, the faceplate 1, as a whole cover, also covers the area of the observation port 6, ensuring the flatness and aesthetics of the top, and preventing the opening from appearing abrupt.
[0033] This utility model's technical solution employs circumferentially distributed buckles and slots for mechanical locking between the front cover 1 and the top cover 3, ensuring a firm connection between the panel 2 and the top cover 3. Combined with a rigid screw connection, this forms a strong external connection, directly resisting external stresses that could cause warping. The internal top cover 3 also acts as a force distribution intermediary, integrating the pushing forces of multiple discrete button springs 41 on the circuit board 4 into a uniform support surface, effectively preventing the panel 2 from being partially lifted due to uneven spring force.
