[0046] See Figure 1 and Figure 2 An embodiment of the present application provides a heat exchange device 100, which includes a main body 20 and an air inlet panel assembly 40 arranged on one side of the main body 20. Air from the external environment flows in through the air inlet panel assembly 40, exchanges heat in the main body 20, and then flows back into the external environment.

[0047] The following describes the structure of the air intake panel assembly 40 of the present application, using the heat exchange device 100 as an electric heater as an example. The following embodiments are provided for illustrative purposes only and do not limit the technical scope of the present application. It is understood that in other embodiments, the heat exchange device 100 may also be other devices equipped with the air intake panel assembly 40, without limitation herein.

[0048] Please combine Figure 1 、 Figure 2as well as Figure 3 As shown, the air inlet panel assembly 40 includes a panel body 41 , an air inlet grille 43 and a filter cover 45 .

[0049] Specifically, the panel body 41 is integrally formed with the outer shell of the main body 20 and defines an air inlet 41a. An air inlet grille 43 is provided on the panel body 41 and covers the air inlet 41a, preventing dust and debris from the external environment from entering the main body 20 through the air inlet 41a. A filter cover 45 is removably mounted on one side of the panel body 41 and covers the air inlet grille 43, further filtering out dust and debris.

[0050] Furthermore, the filter cover 45 can rotate relative to the panel body 41 in a first direction to switch between an unlocked state and a locked state. When the filter cover 45 is in the unlocked state, the filter cover 45 can be separated from the panel body 41 along the first direction. When the filter cover 45 is in the locked state, the filter cover 45 is fixed to the panel body 41.

[0051] In this way, the filter cover 45 can be installed and removed by rotating the filter cover 45, thereby improving the installation convenience of the filter cover 45. At the same time, it can effectively prevent the filter cover 45 from falling off from the panel body 41, ensuring the normal operation and safety of the heat exchange equipment 100, and making the heat exchange equipment 100 have higher safety performance.

[0052] Please continue reading Figures 1 to 3 The shell of the main body 20 is roughly a cubic structure, and the width direction of the main body 20 is defined as the first direction (i.e. Figure 1 The length direction of the main body 20 is the second direction (ie Figure 1 The height direction of the main body 20 is the third direction (i.e. Figure 1 in the Z direction).

[0053] The first direction, the second direction and the third direction intersect with each other. As a preferred embodiment, the first direction, the second direction and the third direction are perpendicular to each other.

[0054] The panel body 41 is disposed on one side of the main body 20 in the first direction. The panel body 41 is a rectangular flat plate structure perpendicular to the first direction. A circular air inlet 41a is formed through the center of the panel body 41. It is understood that the shapes of the panel body 41 and the air inlet 41a are not limited and can be configured as needed.

[0055] The air inlet grille 43 has a mesh structure and includes multiple blades. All blades are arranged at intervals along the third direction. Each blade extends longitudinally along the second direction, and opposite ends of each blade in the second direction are connected to the edge of the air inlet 41a. It will be appreciated that the number, shape, and arrangement of the blades of the air inlet grille 43 are not limited to this and can be configured as needed to meet different air intake requirements.

[0056] The filter cover 45 includes a cover body 452 (such as Figure 5 As shown, the mesh cover body 452 is a generally rectangular, flat plate-like structure. The central region of the mesh cover body 452 comprises a crisscrossing mesh structure, thereby providing both protection and filtering while allowing airflow. It will be appreciated that the mesh structure of the mesh cover body 452 can be of any shape and density and can be customized to meet varying filtering requirements.

[0057] See also Figure 3 、 Figure 4 as well as Figure 5 Furthermore, to unlock and lock the filter cover 45 relative to the panel body 41, the panel body 41 defines a knob slot 41b. The filter cover 45 also includes a knob 454 protruding from one side of the cover body 452 in the thickness direction. When the filter cover 45 is unlocked, the knob 454 passes through the knob slot 41b in a first direction and into the main body 20. When the filter cover 45 is locked, the knob 454 abuts against the side of the panel body 41 facing away from the filter cover 45 in the first direction.

[0058] When installing the filter cover 45, the user aligns the knob 454 of the filter cover 45 with the knob slot 41b on the panel body 41, and then pushes the filter cover 45 in the first direction so that the knob 454 is inserted into the knob slot 41b. At this time, the filter cover 45 is in the unlocked state. The user can then rotate the filter cover 45 in the first direction until the filter cover 45 switches to the locked state. At this time, the knob 454 abuts against the side of the panel body 41 facing away from the filter cover 45 in the first direction, so that the filter cover 45 can no longer be separated from the panel body 41 in the first direction.

[0059] When removing the filter cover 45, the user can rotate the filter cover 45 in the opposite direction around the first direction to the unlocked state. After the knob 454 moves along the knob groove 41b, it can no longer resist the panel body 41 in the first direction, so the user can remove the filter cover 45 from the panel body 41 along the first direction.

[0060] In this way, the filter cover 45 and the panel body 41 are fixed to each other through the rotational cooperation between the screw buckle 454 and the screw buckle groove 41b. The fixing method is relatively stable and can effectively prevent the filter cover 45 from falling off or being damaged, thereby ensuring the normal operation of the heat exchange device 100.

[0061] In some embodiments, the panel body 41 is provided with a plurality of screw-on grooves 41b, all of which are located at the edge of the air inlet 41a and circumferentially spaced around the air inlet 41a, and the length direction of each screw-on groove 41b extends linearly along the tangential direction of the edge of the air inlet 41a or extends in an axially curved manner along the air inlet 41a.

[0062] Corresponding to the arrangement of the knob slots 41b, the filter cover 45 includes a plurality of knobs 454. The knobs 454 are spaced apart and aligned with the knob slots 41b. When the filter cover 45 is unlocked, each knob 454 is positioned within a corresponding knob slot 41b. It is understood that the number, shape, and placement of the knob slots 41b are not limited to this. The number, shape, and placement of the knobs 454 correspond to the knob slots 41b, thereby meeting different securing requirements depending on factors such as the shape of the panel body 41 and the filter cover 45.

[0063] Please combine Figure 5 、 Figure 6 as well as Figure 7 As shown, in one embodiment, each knob 454 is generally L-shaped and includes a first engaging portion 4541 and a second engaging portion 4543. One end of the first engaging portion 4541 is connected to the filter cover 45, and the other end of the first engaging portion 4541 extends perpendicular to the filter cover 45. One end of the second engaging portion 4543 is connected to an end of the first engaging portion 4541 away from the filter cover 45, and the other end of the second engaging portion 4543 bends relative to the first engaging portion 4541 and extends in a direction parallel to the filter cover 45.

[0064] When the filter cover 45 is in the unlocked state, the second clamping portion 4543 is aligned with the spin buckle groove 41b in the first direction, the width of the first clamping portion 4541 in the length direction of the spin buckle groove 41b is smaller than the length of the spin buckle groove 41b, and the width of the second clamping portion 4543 in the length direction of the spin buckle groove 41b is smaller than the length of the spin buckle groove 41b, so the spin buckle 454 can be inserted into or disengaged from the spin buckle groove 41b along the first direction.

[0065] like Figure 8 and Figure 9 As shown, when the filter cover 45 switches from the unlocked state to the locked state, the filter cover 45 rotates around the first direction relative to the panel body 41, and the knob 454 moves along the knob groove 41b until the second clamping portion 4543 is misaligned with the knob groove 41b in the first direction, so that the second clamping portion 4543 is pressed against the side of the panel body 41 facing away from the filter cover 45 in the first direction.

[0066] Furthermore, in some embodiments, a plurality of stopper protrusions 412 are provided on the side of the panel body 41 facing away from the filter cover 45. Each stopper protrusion 412 is located on one side of a corresponding knob slot 41b. When the filter cover 45 is locked, the second engaging portion 4543 of the knob 454 abuts against the stopper protrusion 412 in the first direction.

[0067] Please continue reading Figure 9 As a preferred embodiment, the second engaging portion 4543 of the rotary knob 454 defines a limiting groove 4543a on one side of the surface facing the mesh cover body 452. When the filter cover 45 is locked, one end of the limiting protrusion 412 is embedded in the limiting groove 4543a, thereby preventing the filter cover 45 from rotating and switching from the locked state to the unlocked state. To remove the filter cover 45, simply apply a certain amount of force to the filter cover 45 to disengage the rotary knob 454 from the limiting protrusion 412.

[0068] See also Figure 1 、 Figure 2 as well as Figure 10 In some embodiments, the air inlet grille 43 is protruded from a surface of the panel body 41 facing the air inlet grille 43, and the filter cover 45 is supported on a side of the air inlet grille 43 away from the panel body 41, and at least part of the edge of the filter cover 45 protrudes from the edge of the air inlet grille 43 in the radial direction of the air inlet 41a.

[0069] In this way, the panel body 41, the air inlet grille 43 and the filter cover 45 together form an "H"-shaped power cord storage structure. The power cord 60 of the heat exchange device 100 can be circumferentially wrapped around the outside of the air inlet grille 43 and limited between the air inlet grille 43 and the filter cover 45, thereby avoiding the power cord 60 from being entangled due to lack of effective storage.

[0070] The aforementioned air inlet panel assembly 40 and heat exchanger 100, and the filter cover 45, can be securely mounted on the air inlet 41a by rotating the knob 454 into the knob slot 41b, effectively preventing dust and debris from entering the air inlet 41a and ensuring the normal operation and safe use of the heat exchanger 100. Furthermore, the filter cover 45, the air inlet grille 43, and the panel body 41 together form an "H"-shaped power cord storage structure, allowing users to easily wrap the power cord 60 around it. This not only solves the problem of the power cord 60 being difficult to store and becoming disorganized, but also optimizes the management of the power cord 60 and enhances the ease of use and aesthetics of the heat exchanger 100, thereby improving the user experience.

[0071] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
