[0010] The second blocking member includes a second bottom section, a second middle blocking section and a second top section which are connected in sequence. The second top section is higher than the second bottom section. Two adjacent second middle blocking sections form a second passage which needs to overcome gravity to rise.

[0011] In one embodiment, the second bottom section extends into the first channel, and the height of the second top section corresponding to the second bottom section is higher than the height of the first channel.

[0012] In one of the embodiments, the first bottom section is bent toward the bottom wall of the installation cavity and cooperates with the first middle blocking section to form a water guide portion.

[0013] In one of the embodiments, the second bottom section is bent toward a direction close to the bottom wall of the installation cavity to form a wind guiding portion for guiding wind to the first channel.

[0014] In one embodiment, the first top section and the first middle blocking section are arranged at an angle to form a first blocking portion for blocking water rising along the first middle blocking section.

[0039] Please refer to Figure 1 and 2 The waterproof structure 10 in one embodiment includes: a cabinet 300, a first blocking component 100 and a second blocking component 200. The cabinet 300 is provided with an installation cavity 310, and an air outlet 314 and an air inlet 312 communicated with the installation cavity 310. The first blocking component 100 and the second blocking component 200 are both arranged in the installation cavity 310. The first blocking component 100 and the second blocking component 200 are arranged along the direction from the air outlet 314 to the air inlet 312. The first blocking component 100 is closer to the air outlet 314 than the second blocking component 200. The first blocking component 100 and the second blocking component 200 are used to block rainwater from entering the air inlet 312 along the air outlet 314, and the heat dissipation wind enters along the air inlet 312 and is discharged through the second blocking component 200, the first blocking component 100 and the air outlet 314 in sequence. The reliability of waterproofing is improved through the double blocking effect of the first blocking component 100 and the second blocking component 200.

[0040] Please refer to Figure 3 and Figure 4 Specifically, the first blocking assembly 100 includes at least two spaced apart in the height direction of the mounting cavity 310 (please refer to Figure 3 The first blocking member 110 is arranged in the direction of the double arrow (in the direction of the double arrow), and the second blocking member 210 includes at least two second blocking members 210 spaced apart along the height direction of the installation cavity 310, and the first blocking member 110 and the second blocking member 210 are staggered in sequence along the height direction of the installation cavity 310; two adjacent first blocking members 110 are arranged to form a first channel 118 that needs to overcome gravity to rise, and two adjacent second blocking members 210 form a second channel 218 that needs to overcome gravity to rise, and the second channel 218 is connected to the first channel 118, and the outlet of the second channel 218 is higher than the outlet of the first channel 118.

[0041] The second channel 218 is in communication with the first channel 118 , and the air inlet 312 is in communication with the air outlet 314 through the second channel 218 and the first channel 118 .

[0042] When the waterproof structure 10 is in use, when rainwater enters along the air outlet 314, the two adjacent first blocking members 110 are arranged to form a first channel 118 that needs to overcome gravity to rise, so it is difficult for rainwater to cross the first channel 118 and continue to be transmitted to the second blocking assembly 200 when entering; further, since the two adjacent second blocking members 210 form a second channel 218 that needs to overcome gravity to rise, the second channel 218 is connected to the first channel 118, and the outlet of the second channel 218 is higher than the outlet of the first channel 118, even when rainwater crosses the first channel 118, it will be received by the second channel 218 and it is difficult to cross the second channel 218 and continue to be transmitted to the air inlet 312; in addition, the second blocking member 210 and the first blocking member 110 are staggered, and when rainwater hits the first blocking member 110 and rebounds to the second blocking member 210, the second blocking member 210 can play a certain blocking role to prevent rainwater from being transmitted to the air inlet 312, thereby improving the reliability of waterproofing.

[0043] Optionally, two adjacent first blocking members 110 may surround and form a first channel 118 that needs to overcome gravity to rise. The two first blocking members 110 may be arranged at an angle; or, among the two adjacent first blocking members 110, one of the first blocking members 110 is parallel to the bottom wall of the installation cavity 310, and the other first blocking member 110 is arranged at an angle.

[0044] Optionally, two adjacent second blocking members 210 may surround and form a second channel 218 that needs to overcome gravity to rise. The two second blocking members 210 may be arranged at an angle; or, among the two adjacent second blocking members 210, one of the second blocking members 210 is parallel to the bottom wall of the installation cavity 310, and the other second blocking member 210 is arranged at an angle.

[0045] Please refer to Figure 6 The first blocking member 110 located at the bottom layer and the bottom wall of the installation cavity 310 also form a first channel 118 .

[0046] Please refer to Figure 6 and Figure 7 The first blocking member 110 includes a first bottom section 112, a first middle blocking section 114 and a first top section 116 connected in sequence, and the height of the first top section 116 is higher than the height of the first bottom section 112. Furthermore, a first passage 118 that needs to overcome gravity to rise is formed between the two first middle blocking sections 114 of two adjacent first blocking members 110.

[0047] It should be noted that the height refers to the height relative to the bottom wall of the installation cavity 310 along the height direction of the installation cavity 310 .

[0048] Please refer to Figure 3 and Figure 5The second blocking component 200 is disposed in the installation cavity 310, and the second blocking component 200 is closer to the air inlet 312 than the first blocking component 100. Figure 6 and Figure 7 The second blocking assembly 200 includes at least two second blocking members 210 spaced apart in the height direction of the mounting cavity 310. The second blocking member 210 includes a second bottom section 212, a second middle blocking section 214 and a second top section 216 connected in sequence. The second top section 216 is higher than the second bottom section 212. The second bottom section 212 extends into the first channel 118. The height of the second top section 216 corresponding to the second bottom section 212 is higher than the height of the first channel 118. The two adjacent second middle blocking sections 214 form a second channel 218 that needs to overcome gravity to rise.

[0049] Based on the above examples, please refer to Figure 6 , Figure 6 for Figure 5 The partially enlarged schematic diagram at point B in the middle shows that in the present embodiment, the waterproof structure 10 further includes a water receiving member 400, and the water receiving member 400 and the first blocking component 100 and the second blocking component 200 are all arranged along the height direction of the installation cavity 310, and the water receiving member 400 is arranged below the first blocking component 100 and the second blocking component 200, and the water receiving member 400 is used to receive water flowing down along the first blocking component 110 and the second blocking component 210.

[0050] For further information, please refer to Figure 6 In the present embodiment, the water receiving member 400 is inclined relative to the bottom wall of the installation cavity 310 to discharge the received water. Thus, when rainwater falls onto the water receiving member 400, the water can be discharged more smoothly.

[0051] Please refer to Figure 7 The first bottom section 112 is bent toward the bottom wall of the installation cavity 310 and cooperates with the first middle blocking section 114 to form a water guide portion 1122. In this way, when rainwater hits the first blocking member 110, it can be discharged along the water guide portion 1122 toward the bottom wall of the installation cavity 310 under the action of gravity.

[0052] Furthermore, in order to prevent rainwater from rising along the first intermediate blocking section 114 and passing over the first channel 118, in the present embodiment, the first top section 116 is arranged at an angle to the first intermediate blocking section 114 to form a first blocking portion 1162 for blocking water rising along the first intermediate blocking section 114. When rainwater rises along the first intermediate blocking section 114, it changes direction under the action of the first blocking portion 1162 and drips in a direction falling toward the bottom wall of the installation cavity 310.

[0053] Please refer to Figure 7Specifically, an acute angle is formed between the first middle blocking section 114 and the first top section 116 , and the first top section 116 and the first bottom section 112 are located on opposite sides of the first middle blocking section 114 .

[0054] When water that does not pass through the second channel 218 will slide down the second middle blocking section 214 or drip directly, or when the outside rain is heavy, part of the rain will bounce back between two adjacent second blocking members 210 through the impact of the first channel 118. In order to collect this part of water, in this embodiment, a water collecting portion 220 formed by an inward depression is provided between the second middle blocking section 214 and the second bottom section 212. The water collecting portion 220 is provided with a water leakage port 222. Water is collected by the water collecting portion 220 and discharged through the water leakage port 222. It is necessary to explain that the water collecting portion 220 formed by the inward depression only limits the water collecting portion 220 to be a concave structure, and does not limit the formation method of the water collecting portion 220.

[0055] For further information, please refer to Figure 7 The second top section 216 and the second middle blocking section 214 are arranged at an angle to form a second blocking portion 2162 for blocking water rising along the second middle blocking section 214. The second blocking portion 2162 and the water collecting portion 220 are located on the same side. In this way, when rainwater rises along the second middle blocking section 214, it changes direction under the action of the second blocking portion 2162 and drips in a direction falling toward the bottom wall of the installation cavity 310, preventing rainwater from crossing the second channel 218 and falling to the air inlet 312, thereby improving the reliability of waterproofing.

[0056] Please refer to Figure 3 and Figure 7 The water collecting portion 220 is disposed outside the first channel 118, and the water collecting portions 220 of two adjacent second blocking members 210 are arranged along the height direction of the installation cavity 310 (please refer to Figure 3 The water collecting portion 220 of the second barrier 210 on the lower layer can receive the water discharged along the water leakage port 222 of the second barrier 210 on the upper layer. In this way, the water in the water collecting portion 220 of the second barrier 210 on the upper layer can be discharged to the water collecting portion 220 of the second barrier 210 on the next layer through the water leakage port 222, thereby realizing the drainage function.

[0057] Preferably, in order to ensure the reliability of drainage, the water leakage opening 222 in the second blocking member 210 located at the lower layer may be directly opposite to the water leakage opening 222 of the second blocking member 210 located at the upper layer.

[0058] Based on any of the above embodiments, please refer to Figure 7In this embodiment, one second blocking member 210 corresponds to one first channel 118, and the second top section 216 of the second blocking member 210 is higher than the height of the first top section 116 of the first blocking member 110 forming the first channel 118. In this embodiment, the second top section 216 of the second blocking member 210 is higher than the height of the first top section 116 of the first blocking member 110 located at the upper layer. The term "located at the upper layer" refers to the relative position of the two first blocking members 110 forming the first channel 118. In this way, the second blocking member 210 can more reliably receive the water discharged along the first channel 118.

[0059] The first blocking assembly 100 and the second blocking assembly 200 not only need to block rainwater, but also need to ventilate the air so that the heat dissipation air can be smoothly transmitted from the air inlet 312 to the air outlet 314 for discharge. Figure 4 and Figure 7 In the present embodiment, the first channel 118 and the second channel 218 are connected, and the second bottom section 212 extends into the first channel 118. The second bottom section 212 can serve to transfer the water in the second channel 218 to the first channel 118. The overall inclination trend between the first channel 118 and the second channel 218 is consistent. In this way, when the wind is transmitted in the second channel 218, it is transmitted to the first channel 118 more smoothly.

[0060] For further information, please refer to Figure 7 The second bottom section 212 is bent toward the bottom wall of the installation cavity 310 to form a wind guide portion 2122 for guiding the wind to the first channel 118. In this way, the wind in the second channel 218 is more smoothly discharged into the first channel 118 through the guiding effect of the wind guide portion 2122. Furthermore, the bending of the second bottom section 212 toward the bottom wall of the installation cavity 310 can increase the space for the wind to be discharged into the second channel 218, thereby allowing the wind to be more smoothly discharged into the first channel 118.

[0061] In addition, an embodiment also relates to a cabinet, comprising the waterproof structure 10 in any of the above embodiments.

[0062] The above-mentioned cabinet includes the waterproof structure 10 in any of the above-mentioned embodiments. When in use, when rainwater enters along the air outlet 314, the two adjacent first blocking members 110 are surrounded to form a first channel 118 that needs to overcome gravity to rise, so it is difficult for rainwater to cross the first channel 118 and continue to be transmitted to the second blocking component 200 when entering; further, since the two adjacent second blocking members 210 form a second channel 218 that needs to overcome gravity to rise, the second channel 218 is connected to the first channel 118, and the outlet of the second channel 218 is higher than the outlet of the first channel 118, even when rainwater crosses the first channel 118, it will be received by the second channel 218 and it is difficult to cross the second channel 218 and continue to be transmitted to the air inlet 312; in addition, the second blocking member 210 and the first blocking member 110 are staggered. When rainwater hits the first blocking member 110 and rebounds to the second blocking member 210, the second blocking member 210 can play a certain blocking role to prevent rainwater from being transmitted to the air inlet 312, thereby improving the reliability of waterproofing.

[0063] For further information, please refer to Figure 1 and Figure 2 The cabinet further includes an air supply member 20, and an air outlet of the air supply member 20 is connected to the air inlet 312. Optionally, the air supply member 20 may be a fan.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0065] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0066] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0067] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above 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.
