Description

Technical Field

[0001] This utility model relates to the field of combustible gas detection technology, specifically a pluggable combustible gas detector. Background Technology

[0002] Combustible gas detectors are critical safety devices used to detect leaks of combustible gases in the environment, and are widely used in homes, businesses, and industrial settings. Traditional combustible gas detectors are typically wall-mounted or plugged directly into a wall socket.

[0003] For plug-in detectors, power is typically obtained by directly inserting a power pin on the detector housing into a wall socket. However, existing plug-in detectors usually rely solely on the plug-in connection between the pin and the socket for fixation, resulting in an unstable connection that is prone to loosening or even detaching from the socket when accidentally touched or pulled. Furthermore, the bottom and top shells of existing detectors are often fixed with simple clips or screws, making disassembly and assembly difficult and hindering subsequent maintenance, calibration, or battery replacement. Therefore, we propose a plug-in combustible gas detector. Utility Model Content

[0004] The purpose of this invention is to provide a pluggable combustible gas detector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pluggable combustible gas detector, comprising a bottom shell, a front shell detachably connected to the end of the bottom shell, a three-prong power plug provided on the outer side of the bottom shell, mounting grooves symmetrically formed on the surface of the bottom shell outside the three-prong power plug, and a suction cup for reinforcing the connection between the three-prong power plug and an external socket installed in the mounting groove, two connecting rods integrally provided at the top and bottom of the bottom shell, and two connecting cylinders integrally provided at the top and bottom of the front shell, the connecting rods being slidably inserted into the connecting cylinders.

[0006] Preferably, the top and bottom of the inner wall of the bottom shell are symmetrically fixed with protrusions, and a sliding rod is fixedly fixed to the side of the protrusion away from the connecting rod. Slide plates are symmetrically slidably arranged at both ends of the inner wall of the bottom shell, and sliding holes are opened at the top and bottom of the slide plates. The slide plates are slidably connected to the outside of the two sliding rods. A spring is sleeved on the outside of the sliding rod between the protrusion and the slide plate, and the two ends of the spring are fixedly connected to the protrusion and the slide plate respectively. The top and bottom of the slide plates are integrally provided with protruding plates, and the protruding plates are pressed against the inner wall of the shell.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 This utility model provides a technical solution: a pluggable combustible gas detector, including a bottom shell 1, a front shell 2 detachably connected to the end of the bottom shell 1, a three-prong power plug 3 provided on the outer side of the bottom shell 1, and mounting grooves symmetrically opened on the surface of the bottom shell 1 outside the three-prong power plug 3, and a suction cup 5 for reinforcing the connection between the three-prong power plug 3 and the external socket is installed in the mounting groove. Two connecting rods 6 are integrally provided at the top and bottom of the bottom shell 1, and two connecting cylinders 7 are integrally provided at the top and bottom of the front shell 2, and the connecting rods 6 are slidably inserted into the connecting cylinders 7.

[0023] It should be noted that the detector is equipped with a gas sensor (including semiconductor sensor, catalytic combustion sensor, and electrochemical sensor), a signal processing circuit (preamplifier circuit, analog-to-digital converter, and microcontroller), an alarm unit, a power supply circuit (three-pin power connector 3 and power management module), and a communication interface.

[0024] Insert the three-prong power plug into the connector socket. After plugging in the power, the detector starts up first. The gas sensor (especially semiconductor type) needs a period of time (usually tens of seconds to several minutes) to heat up to its optimal operating temperature. During this time, the indicator light may flash or display "warming up". The microcontroller will perform a system self-test to ensure that the sensor, circuit and alarm are functioning normally. After warming up, the detector enters normal monitoring state. The air in the environment slowly diffuses to the surface of the gas sensor through the pores on the detector housing. The sensor converts the gas concentration information into an electrical signal in real time. After amplification and analog-to-digital conversion, the electrical signal is sent to the microcontroller. The microcontroller compares the value read with two internally preset key thresholds (low alarm threshold: usually corresponding to 10%-25% of the lower explosive limit of gas, issuing a primary alarm; high alarm threshold: usually corresponding to 50% or higher of the lower explosive limit of gas, issuing an emergency alarm). If the concentration is below the low alarm threshold, the detector is silent and the power indicator light is constantly on. If the concentration exceeds the low alarm threshold, the microcontroller triggers the audible and visual alarm. The buzzer emits an intermittent alarm and the red alarm light flashes to remind the user of a possible minor leak. If the concentration exceeds the high alarm threshold... The buzzer will switch to a rapid, continuous alarm sound, and the light will flash at a high frequency to warn the user that danger is imminent. If the sensor is damaged or the circuit malfunctions, the detector will emit a specific audible and visual signal, sending a signal to the connected device at the same time to automatically take safety measures.

[0025] Please see Figure 2 and Figure 4 The top and bottom of the inner wall of the bottom shell 1 are symmetrically fixed with protrusions 8, and the side of the protrusions 8 away from the connecting rod 6 is fixed with a sliding rod 9. The two ends of the bottom shell 1 are symmetrically slidably arranged with sliding plates 10, and the top and bottom of the sliding plates 10 are provided with sliding holes. The sliding plates 10 are slidably connected to the outside of the two sliding rods 9. The outside of the sliding rods 9 is fitted with a spring 11 between the protrusions 8 and the sliding plates 10, and the two ends of the spring 11 are fixed to the protrusions 8 and the sliding plates 10 respectively. The top and bottom of the sliding plates 10 are integrally provided with protruding plates, and the protruding plates are pressed against the inner wall of the face shell 2.

[0026] It should be noted that when using this utility model, when connecting the front shell 2 and the bottom shell 1, first move the two L-shaped levers 18 closer together so that the two sliding plates 10 move closer together at the same time. Then connect the front shell 2 and the bottom shell 1 accordingly so that the connecting rod 6 on the bottom shell 1 is inserted into the connecting cylinder 7 on the front shell 2. Then release the L-shaped levers 18. Under the action of the spring 11, push the two sliding plates 10 away from the protrusion 8 connected to them. The connecting block 12 at the end of the sliding plate 10 is locked into the connecting groove 15 on the fixing block 14. The fixing rod 13 on the sliding plate 10 is locked into the fixing hole 16 on the inner wall of the front shell 2, so that the front shell 2 and the bottom shell 1 are quickly and firmly connected.

[0027] When maintenance is required, pull the two L-shaped levers 18 closer together, so that the slide plate 10 is close to the protrusion 8, the spring 11 is compressed, and then directly separate the face shell 2 from the bottom shell 1. Then release the two L-shaped levers 18. When testing, simply insert the three-prong power plug 3 into the external connection socket to turn on the power. After the three-prong power plug 3 is fully inserted into the socket, continue to press the bottom shell 1. The suction cup 5 on the bottom shell 1 will adhere to the panel of the socket, so that the detector is firmly connected to the socket, ensuring the stability of the connection between the three-prong power plug 3 and the socket, and achieving better detection.

[0028] Please see Figure 2 , Figure 3 and Figure 4 The sliding plate 10 is integrally provided with a connecting block 12 at one end outside the bottom shell 1. The top and bottom ends of the inner wall of the face shell 2 are symmetrically fixed with fixing blocks 14, and the fixing block 14 is provided with a horizontal connecting groove 15 on one side of the bottom shell 1. The connecting block 12 is slidably inserted into the connecting groove 15.

[0029] It should be noted that the connecting block 12 has a T-shaped structure. After the front shell 2 is connected to the bottom shell 1, the two L-shaped levers 18 on the bottom shell 1 are released. Under the action of the spring 11, the slide plate 10 slides toward the protrusion 8. The connecting block 12 at the end of the slide plate 10 is correspondingly locked into the connecting groove 15, so that the front shell 2 and the bottom shell 1 are firmly connected.

[0030] Please see Figure 3 The top and bottom of the two inner walls of the face shell 2 are symmetrically provided with fixing holes 16. The side of the slide plate 10 away from the slide rod 9 is fixed with a fixing rod 13, which is snapped into the fixing hole 16.

[0031] It should be noted that when the front shell 2 is connected to the bottom shell 1, the sliding plate 10 contacts the inner wall of the front shell 2. At this time, the fixing rod 13 on the sliding plate 10 is locked into the fixing hole 16 on the inner wall of the front shell 2, which strengthens the stability of the connection between the front shell 2 and the bottom shell 1.

[0032] Please see Figure 5 The bottom shell 1 has a groove 4 symmetrically provided on the side away from the top shell 2, and a sliding groove 17 is provided in the middle of the groove 4. The middle of the sliding plate 10 is integrally provided with a slider, and the end of the slider passes through the sliding groove 17 and is fixedly connected to an L-shaped lever 18.

[0033] It should be noted that the slider in the middle of the slide plate 10 is slidably connected inside the slide groove 17. By moving the L-shaped lever 18, the sliding of the slide plate 10 inside the bottom shell 1 can be controlled. The groove 4 is designed so that the L-shaped lever 18 is located inside it, making it convenient to move it.

[0034] Please see Figure 6A sealing ring is embedded in the open end of the bottom shell 1, and the sealing ring is in close contact with the open end of the front shell 2.

[0035] It should be noted that the sealing ring ensures a good seal at the connection between the front shell 2 and the bottom shell 1, preventing moisture from entering the detector.
