Description

Technical Field

[0001] The present invention relates to the technical field of alarm devices, and more particularly to a switch device for a carbon monoxide detector. Background Art

[0002] At present, liquefied gas and coal gas have entered thousands of households and have been widely used, bringing many conveniences to people's lives and work, and improving the urban environment. However, they also bring potential dangers to people. Sometimes, gas leakage may occur, endangering people's lives and property. The main source of harm to people's lives and property is carbon monoxide. Carbon monoxide is a colorless and odorless gas. Because it has a high affinity with hemoglobin in the human body, when it is inhaled into the human body, it will compete for oxygen in the blood to form carbon monoxide hemoglobin, causing arterial wall hypoxia and edema, hindering blood flow, and causing people to have adverse symptoms such as fatigue, shortness of breath, nausea, and dizziness. When too much carbon monoxide is inhaled into the body, it may even cause death due to hypoxia.

[0003] According to the current "UL 2034 Single-Station and Multi-Station Carbon Monoxide Alarm" standard, the requirements for carbon monoxide alarms are as follows: 1. The alarm must be powered on after installation; 2. Removing it again after installation does not affect the working state of the alarm; 3. When the alarm expires, it can be discharged (releasing the remaining battery power) and the alarm cannot be installed again; 4. The machine cannot be turned on or off without the help of tools; 5. Tools can be used to turn the machine on and off during the production process. In order to meet the requirements of the standard, similar products currently use rotating installation to achieve the functions required by the standard; this limits the product appearance and does not allow for diversification of appearance.

[0004] In addition, according to the current "Gas detectors - Electrical equipment for carbon monoxide detection in domestic premises BS / EN50291-1:2018" standard requirements for carbon monoxide alarms and the company's requirements for carbon monoxide alarms: 1. The alarm must be turned on after installation; 2. The alarm must be able to be turned off when it is removed again after installation; 3. The power on and off operation can be performed manually.

In addition, in combination with Figure 4 As shown, a plurality of first guide grooves 4042 and first guide strips 4043 are arranged on the surfaces of the upper push rod 404 and the lower push rod 405, a second guide strip (not marked in the figure) is arranged on the inner bottom surface of the bottom shell 20 corresponding to the position of the first guide groove 4042, and a second guide groove (not marked in the figure) is arranged on the inner bottom surface of the bottom shell 20 corresponding to the position of the first guide strip 4043. In this way, the movement of the upper push rod 404 and the lower push rod 405 is guided to improve the accuracy of the movement.

[0053] Reference Figure 6 As shown, the gear positioning block 202 is W-shaped, and the gear buckle 401 can be stuck in the two slots of the gear positioning block 202 and the top of the gear positioning block 202, which respectively correspond to the power on, power off and disabled states of the toggle switch 501; the disabled buckle 402 is V-shaped, and the disabled buckle 402 is stuck in the opening of the disabled positioning block 203, which corresponds to the disabled state of the toggle switch 501.

[0054] For the connection between the upper push rod 404 and the lower push rod 405, refer to Figure 4 , Figure 5 As shown, the lower push rod 405 has a connection buckle 4052 extending toward the upper push rod 404, and the upper push rod 404 is provided with a connection slot 4044 for accommodating the connection buckle 4052; the connection buckle 4052 has a first slot 4053 and a second slot 4054 sequentially arranged along the plugging direction of the connection buckle 4052 and the connection slot 4044, and a protrusion 4045 is arranged in the connection slot 4044, and the protrusion 4045 is used to be stuck in the first slot 4053 or the second slot 4054. Therefore, pushing the upper push rod 404 to move can drive the lower push rod 405 to move, and toggle the toggle switch 501.

[0055] In combination with the above structure, the working process of the on / off device of the carbon monoxide detector of the present invention is described in detail. During installation, the mounting bracket is first fixed to the mounting surface (the mounting surface is a wall in this embodiment), and then the carbon monoxide detector is installed by matching the hook 301 on the mounting bracket 30 with the mounting hole 201; Fig.18 , Fig.19 As shown, the relative positions of the mounting bracket 30, the upper push rod 404 and the lower push rod 405 are shown when the installation is completed. At this time, the gear buckle 401 is located at the first slot position of the gear positioning block 202, the deactivation buckle 402 is located at the bottom of the deactivation positioning block 203, and the protrusion 4045 of the upper push rod 404 is inserted into the first slot 4053 of the lower push rod 405.

[0056] Further, the hook 301 extends into the mounting hole 201 and abuts against the push rod assembly 40 to drive the push rod assembly 40 to translate; the hook 301 of the mounting bracket 30 is installed in the mounting hole 201, and when the mounting bracket 30 moves toward the position of the strip-shaped portion of the mounting hole 201, it drives the upper push rod 404 to move, and the upper push rod 404 drives the lower push rod 405, and the lower push rod 405 pushes the toggle switch 501 to the power-on position; in this embodiment, refer to Figures 15 to 17 As shown in FIG. 1 , the relative positions of the mounting bracket 30, the upper push rod 404 and the lower push rod 405 when the machine is turned on are shown. Fig.18 By comparison, the mounting bracket 30 moves downward, but the position of the lower push rod 405 does not change, and the upper push rod 404 is displaced relative to the lower push rod 405, and at this time, the protrusion 4045 of the upper push rod 404 is inserted into the second slot 4054 of the lower push rod 405. Therefore, by comparison, it can be known that the carbon monoxide detector is in the power-on state after installation, which is more in line with user experience and avoids the situation where the product is forgotten to be turned on after installation.

[0057] Further, combined with Figures 11 to 14 As shown in FIG. 1 , the relative positions of the mounting bracket 30, the upper push rod 404 and the lower push rod 405 when the power is turned off are shown. Fig.15 In comparison, the mounting bracket 30 moves further downward, the upper push rod 404 and the lower push rod 405 move downward, the gear buckle 401 is located at the second slot position of the gear positioning block 202, and the lower push rod 405 pushes the toggle switch 501 to the off position.

[0058] Combination Figure 7 , Figure 8 , Fig. 9 as well as Fig.10As shown, a block 4055 is provided on the side of the lower push rod 405 facing the bottom shell 20, and a switch port for accommodating the block 4055 is provided on the bottom shell 20, and the block 4055 is limited by the switch port; a detachably connected stopper 204 is preset at one end of the switch port. Figure 20 to Figure 22 As shown in the figure, the relative positions of the mounting bracket 30, the upper push rod 404 and the lower push rod 405 when the device is not in use; when the carbon monoxide detector expires and needs to be stopped, the carbon monoxide detector is first removed from the mounting bracket 30, and the block 204 is pried open, and then the block 4055 is pushed at the switch port with a tool. At this time, the lower push rod 405 blocks the positioning hole, and the mounting bracket 30 cannot be installed, and the device enters the discharge state, and the product is no longer used. At this time, the gear buckle 401 of the lower push rod 405 is located at the top of the gear positioning block 202, and the deactivation buckle 402 is located at the top of the deactivation positioning block 203.

[0059] Through the above structure and working process, the present invention provides a carbon monoxide detector power on / off device, which can meet the requirements of being able to start and work normally after the alarm is installed, and not affecting the working state of the alarm when it is removed again after installation; it can be discharged when the carbon monoxide alarm expires, and the carbon monoxide alarm cannot be installed again; the present invention cannot be turned on and off without the help of tools through the design of the above special structure; in addition, during the production process, the power on / off action can be achieved by pushing the card block 4055. Therefore, in the above embodiment, the present invention meets the requirements for carbon monoxide alarms in the current "UL 2034 Single-Station and Multi-Station Carbon Monoxide Alarm" standard.

[0060] Reference Fig.23 , Fig.24 The figure shows a second embodiment of a carbon monoxide detector switch device of the present invention. In this embodiment, the difference is that the push rod assembly 40 includes a first push rod 406. The first push rod 406 has a substantially same structure as the lower push rod 405 in the above embodiment, and also includes a gear buckle 401 and a deactivation buckle 402. Therefore, its structure is not described in detail. In this embodiment, the first push rod 406 is defined as an EN version push rod. Fig.23 , Fig.24 As shown, the inner bottom surface of the bottom shell 20 is provided with a first push rod buckle 4061 , the first push rod 406 is clamped between the opposite first push rod buckles 4061 , and the first push rod 406 can move between the first push rod buckles 4061 .

[0061] Further, combined with Fig.24 As shown, a power on / off handle 4062 is provided on the side of the first push rod 406 facing the bottom housing 20. Fig.25 , Fig.26As shown, the mounting bracket 30 is provided with a through hole 302, and the inner wall of the through hole 302 is provided with opposite elastic arms 303. After the mounting bracket 30 is mounted on the bottom shell 20, the switch handle 4062 is located between the opposite elastic arms 303. When the mounting bracket 30 is not needed, the switch 501 can be manually turned on and off by toggling the switch handle 501.

[0062] During installation, the mounting bracket is first fixed to the mounting surface (the mounting surface is a wall in this embodiment), and then the carbon monoxide detector is installed by cooperating the hook 301 on the mounting bracket 30 with the mounting hole 201. At this time, the switch handle 4062 falls between the two elastic arms 303 of the mounting bracket 30. When the carbon monoxide detector moves downward, the elastic arms 303 push the switch handle 4062 to move, and at the same time, the first push rod 406 drives the toggle switch 501 to turn on the detector. Fig. 27 , Fig.28 As shown, it is a schematic diagram of the position of the first push rod 406 when the device is turned on. When the carbon monoxide detector moves in the opposite direction, the alarm is turned off by moving in the opposite direction. If the first push rod 406 is in the power-on position during installation, the switch handle 4062 squeezes the elastic arm 303 to deform, and the carbon monoxide detector is moved downward, and the switch handle 4062 falls between the two elastic arms 303 of the mounting bracket 30, completing the installation and keeping the device in the power-on state.

[0063] In this embodiment, a power on / off device for a carbon monoxide detector is provided, which is designed in accordance with the standard "Gas detectors - Electrical equipment for carbon monoxide detection in domestic premises BS / EN50291-1:2018". The design of this standard has no deactivation requirements, and according to the product definition, the alarm needs to be turned off after installation and then removed again; the power on and off operation can be performed manually.

[0064] Therefore, the present invention provides a carbon monoxide detector power on / off device, in which a carbon monoxide detector that meets two standards can be realized by replacing only one accessory, which greatly saves research and development costs. In addition, this structural design of the present invention can be used not only for square products but also for round products, making the product appearance design more diverse; the present invention can be applied to smoke alarms, carbon dioxide alarms, and the like that have the same requirements. In addition, it can be turned on immediately after installation, which is more in line with the user experience and also avoids forgetting to turn on the product after installation; the difference between the EN version push rod and the lower push rod 405 is only that the EN version push rod has a power on / off handle 4062, and the lower push rod 405 has a block 4055, so the EN version push rod and the lower push rod 405 can be produced using the same mold. The power on / off test is achieved by pushing the positioning groove on the lower push rod 405 up and down with a tool, but the power on / off cannot be performed by hand.
