Description

Technical Field

[0001] The present invention belongs to the technical field of fire extinguishers, and more specifically, relates to a fire extinguisher device and method using an electronic pressure gauge. Background Art

[0002] At present, as the public and society gradually increase their awareness of fire prevention, fire extinguishers are widely used due to their portability and operability. The pressure gauge on the fire extinguisher usually uses a mechanical pressure gauge because of its simple structure, low maintenance cost, low failure rate, and small impact by temperature and electromagnetic changes. However, this pressure gauge has various defects. First, it is sensitive to vibration and impact. Second, it is easily affected by errors. Finally, its pointer reading can only appear in one physical position, which is not convenient for data collection and processing.

DETAILED DESCRIPTION

[0035] The following will refer to the attached Figure 1-6 Exemplary embodiments of the present invention are described in more detail. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0036] The fire extinguisher device using an electronic pressure gauge described in the present invention includes a fire extinguisher bottle, a connecting pipe, and an electronic pressure gauge. The electronic pressure gauge includes a pressure sensor, a signal conversion module, a central processing unit, a display module, and a power module. The present application also provides a method for displaying using a fire extinguisher device using an electronic pressure gauge. The present application displays accurate pressure data, pressure conditions, and power supply quantity through an electronic display screen. In the process of obtaining pressure information, the data error is small and the accuracy is high, which is convenient for recording and storage, and by displaying the pressure conditions of "excessive pressure", "normal pressure", and "too low pressure", it is more convenient and intuitive, without having to determine the pressure size by estimating like in a mechanical pressure gauge, nor does it need to judge the pressure condition by looking at the color.

[0037] Reference Figures 1 to 5 As shown, the present invention provides a fire extinguisher using an electronic pressure gauge, including a fire extinguisher bottle body and a connecting pipe 1. The connecting pipe 1 is a straight-through connecting pipe 1, made of a non-combustible material with a smooth surface, one end of which is connected to the fire extinguisher bottle body, and the other end of the connecting pipe 1 is connected to the electronic pressure gauge. A first limiting sleeve is provided on the side of the connecting pipe 1 close to the electronic pressure gauge 2, and the first limiting sleeve 101 is fixedly sleeved with the outer wall of the connecting pipe 1. A second limiting sleeve 102 is provided on the side of the connecting pipe 1 close to the fire extinguisher bottle body, and the outer wall of the second limiting sleeve is provided with an external thread, and the connecting pipe 1 is threadedly connected to the fire extinguisher bottle body.

[0038] The minimum range of the electronic pressure gauge 2 is zero, the maximum range is twice the normal working pressure of the fire extinguisher, and the accuracy is 0.5. The electronic pressure gauge includes a pressure sensor 22, a signal conversion module 23, a central processing unit 25, a display module 26, and a power module 24; the pressure sensor 22 monitors the pressure value in the fire extinguisher bottle and transmits the pressure to the signal conversion module 23; the signal conversion module 23 is respectively connected to the power module 24, the pressure sensor 22 and the central processing unit 25, the pressure sensor 22 monitors the pressure value in the fire extinguisher bottle, obtains the pressure information in the bottle, and transmits the pressure information to the signal conversion module 23; the central processing unit 25 is respectively connected to the display module 26, the signal conversion module 23 and the power module 24, the central processing unit 25 is used to compare the converted pressure data with the preset pressure threshold, and the display module 26 displays the pressure data, pressure conditions and power supply through the electronic display screen. The central processor 25 sets the upper limit of the pressure threshold (the setting formula or standard of the threshold) to F1, and the lower limit of the pressure threshold to F2. When the pressure data is greater than F1, the pressure situation is judged as excessive pressure. When the pressure data is greater than F2 and less than F1, the pressure situation is judged as normal pressure. When the pressure data is less than F2, the pressure situation is judged as too low pressure.

[0039] The electronic pressure gauge monitors the pressure in the fire extinguisher bottle and transmits the pressure to the signal conversion module 23. The signal conversion module 23 converts the pressure signal into a digital signal and transmits it to the central processing unit 25. The central processing unit 25 transmits the pressure data, the pressure condition determined according to the threshold value and the power supply to the display module 26. The pressure data obtained in this process has small error and high accuracy, which is convenient for recording and storage. It is more convenient and intuitive by displaying the pressure conditions of "excessive pressure", "normal pressure" and "too low pressure". There is no need to determine the pressure size by estimation like in a mechanical pressure gauge, nor is there any need to judge the pressure condition by checking the color corresponding to the pointer on the pressure dial.

[0040] It also includes: an accelerometer 27, which is arranged on the fire extinguisher bottle body and connected to the signal conversion module. The accelerometer 27 is used to monitor the movement of the fire extinguisher unit, wherein when the accelerometer detects movement, it provides an indication of movement to the mobile terminal.

[0041] The power module 24 has a switch. The power module 24 uses at least one of a lithium battery, a nickel-metal hydride battery or a dry cell. When the fire extinguisher equipment information needs to be checked, the switch is turned on, and after the check is completed, the switch is turned off to save power and extend the use time of the equipment.

[0042] The central processing unit has a Bluetooth module, and the electronic pressure gauge also includes a motion sensor 251 and a direction sensor 252, which transmit the motion data, posture data and direction data of the sprinkler to the CPU with the Bluetooth module. The external receiving device can obtain the motion data, posture data and direction data of the sprinkler through the CPU with the Bluetooth module to grasp the fire situation.

[0043] The electronic pressure gauge further comprises a photoelectric smoke sensor 28 and an ultraviolet flame sensor 29, wherein the photoelectric smoke sensor and the ultraviolet flame sensor are electrically connected to the signal conversion module;

[0044] Among them, the ultraviolet flame sensor detects the intensity of weak ultraviolet light emitted by the flame and transmits the ultraviolet light intensity value to the central processor, which then calculates the flame intensity; at the same time, the photoelectric smoke sensor detects the light intensity affected by the smoke and transmits the light intensity value to the central processor, which then calculates the smoke concentration. When the flame intensity or smoke concentration reaches the alarm threshold, the central processor triggers the motion sensor and direction sensor.

[0045] The present invention provides a method for displaying using the fire extinguisher using the electronic pressure gauge, comprising the following steps:

[0046] S1: Install the electronic pressure gauge on the fire extinguisher bottle through the connecting pipe 1;
