[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] Example 1

[0028] Please refer to Figure 1 and 2 The air outlet grille includes a first rubber block 1, a second rubber block 3, and multiple guide members 2. The first rubber block 1 and the second rubber block 3 are provided with multiple slots 101, which engage with the ends of the guide members 2. The shape of the slots 101 matches the cross-sectional shape of the guide members 2. The first rubber block 1 and the second rubber block 3 cover the ends of the guide members 2. Through the slots 101 on the first rubber block 1 and the second rubber block 3, the first rubber block and the second rubber block 3 are engaged with the guide members 2, eliminating the need for other connecting structures. This design is simple and easy to assemble and disassemble. The first rubber block 1 and the second rubber block 3 covering the ends of the guide members 2 facilitates positioning when connecting them, and the ends of the guide members 2 are not exposed, making the air outlet grille more aesthetically pleasing.

[0029] Please refer to Figure 3 The guide member 2 is a long strip profile, and its cross-section includes a top 201, a middle connecting portion 202, and a bottom 203. The top 201 is rectangular and capable of bearing a certain weight. The middle connecting portion 202 includes two rectangular grooves 202a, which contact the slots 101 of the first rubber block 1 and the second rubber block 3, allowing the guide member 2 to engage with them. The sides of the bottom 203 are composed of a straight line segment 203a and an arc segment 203b. The arc segment 203b facilitates airflow and improves airflow efficiency; the straight line segment 203a guides the airflow, preventing it from entering the first and second grooves in the middle, resulting in more concentrated and smoother airflow and reduced noise. In one embodiment, the length ratio of the arc segment 203b to the straight line segment 203a is 2 to 3. Preferably, the length ratio of the arc segment 203b to the straight line segment 203a is 2.7. In one embodiment, reference Figure 4 The arc segment 203b is a circular arc.

[0030] In one embodiment, reference Figure 5 and 6The first rubber block 1 and the second rubber block 3 each have a recess 102 on one end face and a protrusion 103 on the other end face, with the recess 102 and protrusion 103 engaging with each other. In one embodiment, the recess 102 and protrusion 103 are triangular. Therefore, when the air outlet grille consists of a first rubber block 1, a second rubber block 3, and multiple guide members 2, the protrusion 103 can be cut; when the air outlet is large, the first rubber block 1 and the second rubber block 3 can be connected through the recess and protrusion to form a large-sized air outlet grille. Furthermore, the first rubber block 1 and the second rubber block 3 are relatively easy to cut, allowing for the acquisition of rubber blocks of different sizes. Therefore, the air outlet grille of this embodiment has good versatility.

[0031] In one embodiment, reference Figure 3 The guide component 2 has a hollow structure. On the one hand, compared with a solid structure, the guide component 2 uses less material, which can reduce production costs. On the other hand, since the first rubber block 1 and the second rubber block 3 wrap around the end of the guide component 2, the hollow part of the guide component 2 is blocked by the first rubber block 1 and the second rubber block 3, so water will not accumulate in the hollow part of the guide component 2, and bacteria are not easily generated.

[0032] In one embodiment, the guide member 2 is an aluminum profile. The aluminum profile can be extruded using a mold, making the manufacturing process simple. Furthermore, the aluminum profile has high strength and can withstand a certain weight.

[0033] Example 2

[0034] The air outlet grille of Example 2 is largely similar to that of Example 1, and its common features will not be repeated here. The main difference between Example 2 and Example 1 is that, as Figure 7 As shown, the side of the middle connecting part 202 of the guide member 2 is composed of two inwardly concave curves. Figure 8 To and Figure 7 The guide shown is matched with the first rubber block / second rubber block.

[0035] Referring to Figures 9(a) and 9(b), when the guide member 2 of Embodiment 1 engages with the first rubber block 1 and the second rubber block 3, the force exerted by the guide member 2 on the first rubber block 1 and the second rubber block 3 is only pressure N. At this time, N is the weight G of the guide member 2, i.e., G = N. When the guide member 2 of Embodiment 2 engages with the first rubber block 1 and the second rubber block 3, since the contact surface between the guide member 2 and the first rubber block 1 / second rubber block 3 is curved, relative movement will occur between the guide member 2 and the first rubber block 1 / second rubber block 3, thereby generating a frictional force f between the guide member 2 and the first rubber block 1 / second rubber block 3. Therefore, the force exerted by the guide member 2 on the first rubber block 1 and the second rubber block 3 includes pressure N* and frictional force f. At this time, because of the existence of frictional force f, N* is less than the weight G of the guide member 2. It can be seen that the pressure exerted by the guide member 2 of Embodiment 2 on the first rubber block 1 / second rubber block 3 is less than that of Embodiment 1. Furthermore, the contact area between the guide member of Embodiment 2 and the first rubber block 1 / second rubber block 3 is larger than that of Embodiment 1. Therefore, when the side of the middle connecting part 202 of the guide member 2 is two inwardly concave curves, the pressure of the guide member 2 on the first rubber block 1 and the second rubber block 3 is reduced, the first rubber block 1 and the second rubber block 3 are not easily crushed, and the material strength requirements of the first rubber block 1 and the second rubber block 3 are low; at the same time, the setting of the curve is conducive to the discharge of the wind entering the middle connecting part 202, and it is not easy for wind to accumulate.

[0036] In one embodiment, the roughness of the contact area between the intermediate connecting portion 202 and the slot 101 is greater than that of other parts of the guide member 2. As a result, the pressure of the guide member 2 on the first rubber block 1 and the second rubber block 3 is further reduced, and the strength requirements of the materials of the first rubber block 1 and the second rubber block 3 are further reduced, which is beneficial to cost saving.

[0037] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
