Therefore, it is very necessary to monitor the concentration of harmful gases in the working environment.

[0003] Most of the toxic and harmful gas alarm devices in the prior art can only perform an alarm function when toxic and harmful gases are detected, but cannot effectively purify the toxic and harmful gases, cannot provide effective protection for the staff, and have low practicality. Utility Model Content

The toxic gas detection sensor runs through the detection chamber.

[0010] Through the above technical solution, when the toxic gas detection sensor detects the presence of toxic gas in the environment, it feeds back a signal to the single chip microcomputer, so that the single chip microcomputer controls the buzzer to sound an alarm, prompting surrounding staff to evacuate, thereby improving safety.

[0011] As a further improvement of the above solution, an intake fan is fixedly installed inside the intake pipe, an exhaust fan is fixedly installed inside the exhaust pipe, and filters are provided at the ends of the intake pipe and the exhaust pipe.

[0012] Through the above technical solution, the filter setting can block the entry of external dust, ensuring the accuracy of the test results while increasing the service life of the equipment.

[0013] As a further improvement of the above solution, the bottom of the box is fixedly connected to a base, the bottom of the base is fixedly installed with walking wheels, and one side of the base is fixedly connected to an armrest.

[0014] Through the above technical solution, the armrest pushes the base to move through the walking wheels, thereby driving the equipment to move, which is convenient for changing different working environments and is practical.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0024] Please combine Figure 1 - Figure 3 A toxic environment detection alarm mechanism of the present embodiment includes a box body 1, a detection chamber 4 is arranged inside the box body 1, the top of the detection chamber 4 is connected to an air inlet pipe 2, and one side of the detection chamber 4 is connected to an exhaust pipe 8, a detection component is arranged at the bottom of the detection chamber 4, which is used to detect toxic gases in the air and alarm, and a purification mechanism used in conjunction with the exhaust pipe 8 is arranged inside the box body 1, which is used to filter toxic gases.

[0025] Please combine Figure 2 and Figure 3 The purification mechanism includes a stepper motor 10 fixedly mounted on the top inner wall of the box body 1. The output end of the stepper motor 10 is connected to a rotating shaft 12 through a transmission assembly 11. One end of the rotating shaft 12 is fixedly connected to a turntable 13. A plurality of activated carbon plates 14 corresponding to the exhaust pipe 8 are arranged inside the turntable 13. The transmission assembly 11 includes bevel gears connected to the rotating shaft 12 and the stepper motor 10 respectively, and the bevel gears are meshed with each other.

[0026] The toxic gas passing through the exhaust pipe 8 passes through the activated carbon plate 14 and then is discharged as purified gas. To ensure a continuous purification effect, the turntable 13 can be driven to rotate by the stepper motor 10, and a new activated carbon plate 14 can be replaced in the exhaust pipe 8 to improve the purification effect.

[0027] Please combine Figure 2 The turntable 13 penetrates and rotates inside the exhaust pipe 8 , the activated carbon plate 14 is located inside the exhaust pipe 8 , and a filter membrane 15 is provided inside the exhaust pipe 8 .

[0028] Please combine Figure 2 The detection component includes a single chip microcomputer 5 fixedly installed inside the box body 1. The single chip microcomputer 5 is also electrically connected to a buzzer 7 and a toxic gas detection sensor 6. The toxic gas detection sensor 6 runs through the detection chamber 4.

[0029] When the toxic gas detection sensor 6 detects the presence of toxic gas in the environment, it feeds back a signal to the single chip microcomputer 5, so that the single chip microcomputer 5 controls the buzzer 7 to sound an alarm, prompting surrounding staff to evacuate, thereby improving safety.

[0030] Please combine Figure 2 An intake fan 3 is fixedly installed inside the intake pipe 2, an exhaust fan 9 is fixedly installed inside the exhaust pipe 8, and filters 16 are provided at the ends of the intake pipe 2 and the exhaust pipe 8.

[0031] The filter 16 is set to block the entry of external dust, thereby ensuring the accuracy of the test results and increasing the service life of the equipment.

[0032] Please combine Figure 1 The bottom of the box body 1 is fixedly connected with a base 17 , the bottom of the base 17 is fixedly installed with a walking wheel 18 , and one side of the base 17 is fixedly connected with an armrest 19 .

[0033] The armrest 19 pushes the base 17 to move through the walking wheels 18, thereby driving the equipment to move, making it convenient to change different working environments and having practicality.

[0034] The implementation principle of a toxic environment detection alarm mechanism in the embodiment of the present application is as follows: when working, the air intake fan 3 works to allow air to enter the detection chamber 4 through the air intake pipe 2. When the toxic gas detection sensor 6 does not detect toxic gas, the exhaust fan 9 works to filter the air through the activated carbon plate 14 and the filter membrane 15 and then discharge it to improve the air quality. If the toxic gas detection sensor 6 detects toxic gas, the signal is fed back to the single-chip microcomputer 5, so that the single-chip microcomputer 5 controls the buzzer 7 to sound an alarm. At the same time, the single-chip microcomputer 5 controls the stepper motor 10 to rotate one step, and drives the turntable 13 to rotate one step through the transmission assembly 11, so that the new activated carbon plate 14 is replaced in the exhaust pipe 8 to ensure the purification effect. When the working environment is changed, the equipment can be pushed to move by the handrail 19.

[0035] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
