Description

Technical Field

[0001] The present application belongs to the field of detection technology, and specifically relates to a detector and an equipment cabin. Background Art

[0002] A detector is a device used to detect, measure or identify specific substances or phenomena. For example, a smoke and temperature detector can measure smoke particles and temperature changes at the same time to effectively detect fire.

[0003] For a closed equipment cabin, the detector is installed by extending the air intake of the detector into the cabin of the equipment cabin, and fixing the detection part of the detector on the outside of the cabin for user observation. However, due to assembly errors and processing errors of the detector or the cabin wall, there is a gap between the detection part and the cabin wall, resulting in poor sealing between the detection part and the cabin wall. In this way, water from the outside can easily enter the equipment cabin through the gap between the detection part and the cabin, thereby causing damage to the equipment in the equipment cabin.

[0004] Therefore, in the prior art, there is a problem of poor sealing effect between the detector and the cabin body of the equipment cabin. Utility Model Content

[0005] The purpose of the embodiments of the present application is to provide a detector and an equipment cabin that can solve the problem of poor sealing between the detector and the cabin body of the equipment cabin in the related art.

[0006] In a first aspect, an embodiment of the present application provides a detector, comprising:

[0007] The detector body comprises a detection part and an air inlet part connected to the detection part, wherein the air inlet part is used to extend into the cabin body of the equipment cabin, and the detection part is used to be arranged outside the cabin body and connected to the bulkhead of the cabin body;

[0008] A sealing member, wherein the sealing member is used to be arranged between the detection part and the bulkhead and is arranged around the air inlet part. The sealing member is sealed and connected to the detection part, and a sealing rib ring is arranged on the side of the sealing member away from the detection part. The sealing rib ring protrudes away from the detection part and is used to seal and fit with the bulkhead.

[0009] In a second aspect, an embodiment of the present application further provides an equipment cabin, comprising a cabin body and the above-mentioned detector, wherein an air intake portion of the detector extends into the cabin body, and a detection portion of the detector is located outside the cabin body and connected to a bulkhead of the cabin body.

[0010] In the embodiment of the present application, after the detector is installed on the cabin body of the equipment cabin, interaction forces are generated among the cabin wall, the seal, and the detector body. The seal can be closely attached to the cabin wall and the detection part of the detector body respectively to seal the gap between the cabin wall and the detection part. Thus, it can effectively prevent external water, etc. from entering the equipment cabin through the gap between the cabin wall and the detection part. Moreover, the sealing rib ring on the seal can block external water, etc., so that external water, etc. cannot enter the equipment cabin through the mounting hole on the cabin wall. Therefore, the sealing performance between the detector and the cabin body of the equipment cabin can be improved to ensure the waterproof performance of the equipment cabin.

[0029] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0030] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same type, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0031] Next, the detector and the equipment cabin provided in the embodiments of the present application will be described in detail in conjunction with the accompanying drawings through specific embodiments and their application scenarios.

[0032] Reference Figures 1 - 7A detector provided in an embodiment of the present application may include a detector body 200. The detector body 200 may include a detection part 210 and an air intake part 220. The air intake part 220 may be connected to the detection part 210, and the air intake part 220 may be used to extend into a cabin body of an equipment cabin. The detection part 210 may be used to be arranged outside the cabin body and to be connected to a cabin wall 100 so that the detector body 200 can be installed on the cabin body.

[0033] Here, the air inlet 220 may be provided with a plurality of air inlet holes 221 for the gas in the equipment compartment to enter. For example, the detector body 200 may detect smoke, and when a fire occurs in the equipment compartment, the smoke in the equipment compartment may enter the air inlet 220 through the air inlet holes 221, and the smoke may enter the detection unit 210, so as to be detected by the components in the detection unit 210 and generate a fire alarm.

[0034] In order to ensure the waterproof performance of the equipment compartment, the detector may also include a seal 300. The seal 300 can be used to be arranged between the detection part 210 and the bulkhead 100. The seal 300 can be arranged around the air inlet part 220. The seal 300 can be sealed and connected to the detection part 210. In addition, a sealing rib ring 310 can be provided on the side of the seal 300 away from the detection part 210. The sealing rib ring 310 protrudes away from the detection part 210 and can be used to seal and fit with the bulkhead 100.

[0035] After the detector is installed on the body of the equipment cabin, an interaction force is generated between the bulkhead 100, the seal 300 and the detection part 210 of the detector body 200. The seal 300 can be tightly fitted with the bulkhead 100 and the detection part 210 of the detector body 200 respectively to seal the gap between the bulkhead 100 and the detection part 210, thereby effectively preventing external water from entering the equipment cabin through the gap between the bulkhead 100 and the detection part 210, and the sealing rib 310 on the seal 300 can block external water, so that external water cannot enter the equipment cabin through the installation hole 110 on the bulkhead 100, thereby improving the sealing between the detector body 200 and the body of the equipment cabin to ensure the waterproof performance of the equipment cabin.

[0036] Here, the seal 300 can be connected to the detection part 210 by using the second fixing part 230 described below or adhered to the detection part 210 through an adhesive tape to achieve the sealed connection between the seal 300 and the detection part 210. In this way, the seal 300 can be stably fixed on the detector main body 200. When installing the detector, the installation process can be made more convenient. There is no need to perform extra steps for fixing the seal 300 during installation, and the detector can be directly installed on the bulkhead 100. In addition, when disassembling and assembling the detector, there is no need to disassemble the detector main body 200 and then install or disassemble it. It can be disassembled and assembled as a whole, and the installation is convenient and fast.

[0037] In an alternative embodiment of the present application, the detection part 210 can be connected to the bulkhead 100 through a first fixing part. The first fixing part can be located outside the sealing rib 310. In this way, the assembly gap existing between the first fixing part, the detection part 210, and the bulkhead 100 can be isolated outside the sealing rib 310 to prevent external water, etc. from entering between the seal 300 and the bulkhead 100 through this assembly gap and then entering the interior of the cabin, thereby improving the sealing performance between the detector main body 200 and the bulkhead 100 of the cabin.

[0038] In other embodiments, the first fixing part can also be located inside the sealing rib 310.

[0039] Optionally, a first connection hole 2101 can be provided on the detection part 210, a second connection hole 330 can be provided on the seal 300. The second connection hole 330 can be located outside the sealing rib 310. A fixing hole 120 can be provided on the bulkhead 100. The first fixing part can sequentially pass through the first connection hole 2101 and the second connection hole 330 and be connected to the fixing hole 120. In this way, both the sealing effect of the seal 300 can be improved and the connection strength between the seal 300 and the detection part 210 can be enhanced. Here, the first fixing part can be a screw, specifically a press rivet screw.

[0040] Further optionally, at least two first connection holes 2101 can be provided on the detection part 210. Each first connection hole 2101 can be evenly distributed along the circumferential direction of the detection part 210. At least two second connection holes 330 can be provided on the seal 300. At least two fixing holes 120 can be provided on the bulkhead 100. Each second connection hole 330 and each fixing hole 120 correspond to each first connection hole 2101 one by one. In this way, the stability of the fixation of the detector main body 200 can be improved, and the sealing effect of the seal 300 can also be enhanced.

[0041] In an alternative embodiment, the seal 300 may be connected to the detection portion 210 by a second fixing member 230. The second fixing member 230 may be located inside the sealing rib 310 to isolate the assembly gap existing between the second fixing member 230 and the detection portion 210 inside the sealing rib 310. In this way, external water and the like cannot enter the inside of the sealing ring through the assembly gap between the second fixing member 230 and the detection portion 210, so as to improve the sealing performance between the seal 300 and the detection portion 210, and further improve the sealing performance between the detector main body 200 and the cabin wall 100 of the cabin.

[0042] Of course, the second fixing member 230 may also be located outside the sealing rib 310.

[0043] In other embodiments, the seal 300 may also be integrally injection-molded with the detection portion 210, or the seal 300 may be adhesively bonded to the detection portion 210 with back glue.

[0044] In an alternative embodiment, the sealing rib 310 may include a first rib portion 311 and a second rib portion 312. The first rib portion 311 may be provided with a U-shaped groove 3111, that is, the first rib portion 311 is of a U-shaped structure. The first fixing member may be located within the U-shaped groove 3111, and the notch of the U-shaped groove 3111 may be arranged facing away from the air inlet portion 220. In this way, the first fixing member can be avoided, and the distribution area of the sealing rib 310 can be increased to further improve the sealing effect of the seal 300. And, the second rib portion 312 may be connected to the first rib portion 311, and the second rib portion 312 may be located on the side of the second fixing member 230 facing away from the air inlet portion 220, so that the second fixing member 230 is located inside the sealing rib 310.

[0045] With such an arrangement, the first fixing member and the second fixing member can be distributed on the same circumference, which is beneficial to reducing the size of the seal 300 and the detection portion 210, and thus beneficial to miniaturizing the detector.

[0046] Optionally, the sealing rib 310 may include at least two first rib portions 311 and at least two second rib portions 312. The number of the first rib portions 311 is consistent with the number of the first fixing members, and the number of the second rib portions 312 may be consistent with the number of the second fixing members. The specific number of the first rib portions 311 and the second rib portions 312 is not specifically limited here and may be set according to actual needs.

[0047] In other embodiments, the sealing rib 310 may be of an annular structure, and the sealing rib 310 is located between the first fixing member and the second fixing member 230.

[0048] In an alternative embodiment of the present application, the detection unit 210 may include a housing 211, a detection circuit board 212, and a light guide column 213. The detection circuit board 212 may be located inside the housing 211, and detection elements may be provided on the detection circuit board 212. The detection elements may be used to detect the incoming gas. For example, the detection elements may be used to detect the smoke concentration in the incoming gas to determine whether a fire has occurred inside the cabin. The light guide column 213 may be disposed opposite to the light-emitting elements on the detection circuit board 212 so as to be able to guide out the light of the light-emitting elements, thereby facilitating the user's observation.

[0049] Wherein, a first through hole 2113 may be provided on the side wall of the housing 211 away from the air inlet portion 220. A first portion of the light guide column 213 may be located inside the first through hole 2113, and a first convex portion 214 may be provided inside the housing 211. A second through hole 2141 may be provided on the first convex portion 214. The second through hole 2141 may be coaxially communicated with the first through hole 2113. A second portion of the light guide column 213 may be located inside the second through hole 2141, and the second portion of the light guide column 213 may be connected to the hole wall of the second through hole 2141 by a first sealant 215. In this way, the gap between the light guide column 213 and the housing 211 can be filled and sealed by the first sealant 215, thereby improving both the fixing stability of the light guide column 213 and the sealing performance of the detection unit 210 to prevent external water, etc. from entering the cabin through the detector main body 200, and thus improving the waterproof performance of the cabin.

[0050] In other embodiments, the first convex portion 214 may not be provided inside the housing 211, the light guide column 213 may not be connected to the housing 211 by the first sealant 215, and a part of the light guide column 213 may only extend into the first through hole 2113.

[0051] Optionally, a connecting convex portion 2142 may be provided inside the first through hole 2113. The connecting convex portion 2142 may protrude away from the first through hole 2113, and the connecting convex portion 2142 may be embedded in the first sealant 215. In this way, the connection strength between the first sealant 215 and the hole wall of the first through hole 2113 can be improved, and the sealing performance of the first sealant 215 can be improved. Of course, the connecting convex portion 2142 may not be provided inside the first through hole 2113.

[0052] In an alternative embodiment, the detection unit 210 may further include a pluggable terminal 216. An installation groove 2114 may be provided on the side wall of the housing 211 away from the air intake portion 220. A part of the pluggable terminal 216 may be embedded in the installation groove 2114. Further, a second convex portion 218 may be provided in the housing 211. A third through hole 2181 may be provided on the second convex portion 218. The third through hole 2181 may communicate with the installation groove 2114. Specifically, a communication hole 21141 may be provided on the groove wall of the installation groove 2114 facing the notch of the installation groove 2114. The communication hole 21141 may communicate the installation groove 2114 with the third through hole 2181. The connection pin 2161 of the pluggable terminal 216 may extend into the third through hole 2181 and be electrically connected to the detection circuit board 212. And the connection pin 2161 and the hole wall of the third through hole 2181 may be connected by a second sealant 219. In this way, the gap between the connection pin 2161 and the hole wall of the third through hole 2181 can be filled and sealed by the second sealant 219. Further, the connection strength between the pluggable terminal 216 and the housing 211 can be improved, and the sealing performance of the detection unit 210 can be further improved, so as to prevent external water and the like from entering the cabin interior through the detector main body 200, thereby improving the waterproof performance of the cabin.

[0053] In other embodiments, the second convex portion 218 may not be provided in the housing 211, and the connection pin 2161 of the pluggable terminal 216 may not be connected to the housing 211 through the second sealant 219.

[0054] In an alternative embodiment, a sealing sleeve 217 may be provided between the pluggable terminal 216 and the groove wall of the installation groove 2114. In this way, the sealing sleeve 217 can seal the gap between the pluggable terminal 216 and the groove wall of the installation groove 2114. On the one hand, it can prevent the phenomenon of glue overflow during the process of injecting liquid sealant into the third through hole 2181 to form the second sealant 219. On the other hand, it can also improve the connection strength and sealing performance between the pluggable terminal 216 and the housing 211.

[0055] Of course, the sealing sleeve 217 may not be provided between the pluggable terminal 216 and the groove wall of the installation groove 2114.

[0056] Here, the sealing sleeve 217 may be made of materials such as silica gel or rubber.

[0057] In an alternative embodiment of the present application, the housing 211 may include an outer shell 2111 and a cover plate 2112. The outer shell 2111 may be provided with a receiving groove 2118. The detection circuit board 212 may be located within the receiving groove 2118. The cover plate 2112 may be disposed around the air intake portion 220 and connected to the air intake portion 220 as an integral structure. Moreover, the cover plate 2112 and the air intake portion 220 may close the notch of the receiving groove 2118 to enclose the detection circuit board 212 within the receiving groove 2118.

[0058] Wherein, the outer shell 2111 may be connected to the seal 300, the cover plate 2112, and the detection circuit board 212 through the second fixing member 230. In this way, only through the second fixing member 230, the outer shell 2111, the seal 300, the cover plate 2112, and the detection circuit board 212 can be connected together, thereby reducing the number of fixing members and the number of openings on the outer shell 2111, which is beneficial to simplifying the structure of the detection portion 210 and improving the sealing performance of the detection portion 210.

[0059] In other embodiments, the outer shell 2111 may be connected to the seal 300 through the second fixing member 230, the cover plate 2112 may be connected to the outer shell 2111 through the third fixing member, and the detection circuit board 212 may be connected to the outer shell 2111 through the fourth fixing member.

In this way, the connection strength between the outer shell 2111 and the seal 300, the cover plate 2112, and the detection circuit board 212 can be improved.

[0061] In the present embodiment, at least two third connection holes 320 may be provided on the seal 300, at least two fourth connection holes 2115 may be provided on the outer shell 2111, at least two fifth connection holes 2116 may be provided on the cover plate 2112, and at least two sixth connection holes 2121 may be provided on the detection circuit board 212.
