Abstract

The utility model discloses a carbon monoxide detector, which comprises a casing and a main board installed in the casing, the main board is divided into an output circuit board and a measurement circuit board, and the output circuit board and the measurement circuit board are installed side by side In the housing, an output circuit and its components are integrated on the output circuit board, and a measurement circuit and its components are integrated on the measurement circuit board. Since the main board is divided into two and they are vertically installed in the housing, the space in the housing is fully utilized, so the volume of the entire carbon monoxide detector becomes smaller, which is convenient for maintenance and portability.

Description

carbon monoxide detector

technical field

The utility model relates to a carbon monoxide detector, in particular to a carbon monoxide detector which is small in size, easy to maintain and easy to carry.

Background technique

Carbon monoxide detectors are often used in industrial and mining environments to continuously monitor the percentage of carbon monoxide in the air. Currently known carbon monoxide detectors are mainly composed of a housing and a main board installed in the housing. Yet almost all components and parts (comprising measuring circuit and components thereof, output circuit and components and components thereof) of the known carbon monoxide detector are all integrated on this main board, because there are many components and components that need to be integrated, it is not easy to maintain, And the size of the main board is larger, so that the whole carbon monoxide detector has a larger volume and is inconvenient to carry. In addition, the main board.

Utility model content

The purpose of the utility model is to provide a carbon monoxide detector which is small in size, easy to maintain and easy to carry.

In order to achieve the above object, the utility model provides a carbon monoxide detector, including a housing and a main board installed in the housing, the main board is divided into an output circuit board and a measurement circuit board, and the output circuit board and the measurement circuit The boards are vertically installed in the casing side by side, the output circuit and its components are integrated on the output circuit board, and the measurement circuit and its components are integrated on the measurement circuit board.

In the carbon monoxide detector of the present utility model, the output circuit board is located in front of the measuring circuit board.

In the carbon monoxide detector of the utility model, the housing is composed of a front housing, a rear housing upper cover, a rear housing lower cover and a housing end cover that are engaged with each other.

In the carbon monoxide measuring device of the present utility model, an audible alarm and a display screen are respectively installed on the upper and middle parts of the front housing, and an alarm light is installed on the front housing on the left side of the display screen. Both the sound alarm and the warning light are connected with the output circuit on the output circuit board.

In the carbon monoxide detector of the present utility model, the upper cover of the rear housing is provided with clips.

In the carbon monoxide detector of the utility model, the main board is divided into two into an output circuit board and a measurement circuit board, and they are vertically installed in the housing. The output circuit board is integrated with an output circuit and its components, and the measurement circuit board The measurement circuit and its components are integrated to make full use of the space in the housing and reduce the size of the main board. Therefore, the volume of the entire carbon monoxide detector becomes smaller and more convenient to carry. Moreover, the main board is divided into two. If One of them is damaged, and only the damaged motherboard needs to be replaced accordingly, while the other one does not need to be replaced, which is more convenient for maintenance and reduces the cost.

Detailed ways

The specific embodiment of the utility model is described in detail below in conjunction with accompanying drawing:

With reference to Fig. 1 and shown in Fig. 2, the carbon monoxide detector of the present embodiment comprises the main board that is made of output circuit board 5 and measurement circuit board 6, and is made up of front housing 1, rear housing upper cover 2, rear housing lower cover 3 and the shell end cover 4 are snapped together to form a shell. The output circuit board 5 and the measurement circuit board 6 are vertically fixed in the casing by screws, and the output circuit board 5 is located in front of the measurement circuit board 6 . Wherein, the output circuit board 5 is integrated with the output circuit and its components, and the measurement circuit board 6 is integrated with the measurement circuit and its components. The top and the middle part of the front housing 1 are respectively equipped with an audible alarm 8 and a display screen 7 , and an alarm lamp 9 is installed on the front housing 1 on the left side of the display screen 7 . The display screen 7, the sound alarm 8 and the warning light 9 are all connected with the output circuit on the output circuit board 5. Among them, the display screen 7 is used to display the carbon monoxide measurement result, the sound alarm 8 is used to perform audible alarm when the carbon monoxide measurement result exceeds the set standard value, and the alarm lamp 9 is used to perform a sound alarm when the carbon monoxide measurement result exceeds the set standard value. light alarm. In addition, a clip 10 is bonded to the upper part of the upper cover 2 of the rear case, and the clip 10 can be hung on a belt when carrying, which is very convenient.

The above embodiments only describe preferred implementations of the present utility model, and are not intended to limit the scope of the present utility model. All variations and improvements should fall within the protection scope determined by the claims of the present utility model.
