Description

Technical Field

[0001] This utility model relates to the field of gas-fired heating and hot water boiler technology, specifically a gas-fired heating and hot water boiler that prevents gas leakage. Background Technology

[0002] Gas-fired heating and hot water boilers are widely used in modern homes and many commercial establishments. Due to the flammable and explosive nature of gas, gas leaks can cause serious safety accidents, such as fires and explosions, posing a huge threat to people's lives and property. Therefore, ensuring the safety of gas-fired heating and hot water boilers during use is of paramount importance.

[0003] Utility model patent application CN219346808U discloses a hot water heater with a gas leak prevention structure. The technical solution includes: a hot water heater body, a signal box, and a detection box. A back plate is bolted to the back of the hot water heater body, and mounting nails are movably inserted into the back plate. A detection box is located on one side of the upper surface of the hot water heater body. A gas sensor is bolted to the bottom of the inner wall of the detection box. Square holes are symmetrically opened on both sides of the detection box. A pump box is located on the other side of the upper surface of the hot water heater body. A negative pressure pump is fixed to the bottom of the inner wall of the pump box. A suction pipe is provided at the suction end of the negative pressure pump, and the other end of the suction pipe is inserted into the detection box. This utility model, through the cooperation of the structures, has the function of monitoring gas leaks, which can effectively prevent gas leaks from causing significant safety hazards.

[0004] The hot water boiler with gas leak prevention structure disclosed in the above document has the following defects: When the technical solution draws air into the detection mechanism, dust and other impurities inevitably exist around the gas heating hot water boiler. These impurities may be sucked into the detection equipment, interfering with the detection results and causing the detection mechanism to make misjudgments. For example, dust may adhere to the detection sensor, affecting the sensor's accurate detection of key indicators such as gas concentration.

[0005] Therefore, it can be seen that the existing hot water boilers with gas leak prevention structures do not have a structure to prevent dust from entering the detection area. It is necessary to improve the existing shortcomings and provide a gas-fired heating hot water boiler that prevents gas leaks. Utility Model Content

[0006] The purpose of this utility model is to provide a gas-fired heating and hot water boiler that prevents gas leakage, so as to solve the problem mentioned in the background art that the existing technology does not have a structure to prevent dust from entering the detection area, which may cause dust to adhere to the detection sensor and affect the sensor's accurate detection of key indicators such as gas concentration.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a gas-fired heating and hot water boiler with gas leakage prevention, comprising a boiler body, several sets of gas connection pipes installed on one side of the boiler body, a housing fixedly installed on the upper surface of the boiler body, a first chamber and a second chamber respectively opened inside the housing, a detection mechanism installed inside the second chamber, a signal box fixedly installed on the upper surface of the boiler body, a controller installed inside the signal box, an alarm installed inside the signal box, and a suction mechanism installed inside the first chamber, the suction mechanism including a suction pump, an outlet pipe and a suction pipe, the suction pump fixedly installed inside the first chamber, the outlet pipe fixedly installed at the output end of the suction pump, the outlet pipe being connected to the interior of the second chamber, and the suction pipe fixedly installed at the output end of the suction pump.

[0009] Furthermore, the air suction mechanism also includes a dust collection box and a connector slot. The dust collection box is fixedly installed at one end of the air suction pipe. The dust collection box has a connector slot inside. The dust collection box is fixedly installed on one side of the hot water boiler body.

[0010] Furthermore, the suction mechanism also includes a filter plate mounting seat, in which the filter plate mounting seat is inserted into the insertion slot, and one end of the filter plate mounting seat abuts against the outer surface of the dust collection box.

[0011] Furthermore, the suction mechanism also includes connecting screws, and the filter plate mounting base is connected to the dust collection box via the connecting screws.

[0012] Furthermore, the air intake mechanism also includes a dustproof plate, and the dustproof plate is fixedly installed on the inner wall of the filter plate mounting base.

The connecting pipe is fixedly installed on the lower surface of the dust collector, and a suction head is fixedly installed at one end of the connecting pipe. The suction head is installed on the outer surface of the hot water heater body and is positioned above the gas connecting pipe.

[0014] This utility model has the following beneficial effects:

[0015] (1) This utility model draws air from around the hot water heater body, especially near the gas connection pipe, by starting the air pump and drawing air through the air suction pipe. Because the air suction head is set above the gas connection pipe, the air will pass through the dust collection box before being sucked into the air suction pipe. The dust collection box has a filter plate mounting seat with a dustproof plate, which can perform preliminary dust removal and filtration on the air to prevent dust and other impurities from entering the subsequent testing mechanism. The dust collection box in the air suction mechanism can prevent dust and other impurities from entering the testing mechanism, reduce the misjudgment caused by dust and other impurities in the testing mechanism, and also help extend the service life of the testing mechanism and reduce equipment maintenance costs.

[0016] (2) By setting the air intake head above the gas connection pipe, this utility model can more effectively collect air samples from areas where there may be gas leaks, thereby improving the accuracy of detection.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1 - Figure 4 As shown, this utility model is a gas-fired heating hot water boiler with gas leakage prevention, including a hot water boiler body 1. Several sets of gas connection pipes 101 are installed on one side of the hot water boiler body 1. A box 2 is fixedly installed on the upper surface of the hot water boiler body 1. The box 2 has a first chamber 201 and a second chamber 202 respectively. A detection mechanism 4 is installed inside the second chamber 202. A signal box 5 is fixedly installed on the upper surface of the hot water boiler body 1. A controller 6 is installed inside the signal box 5. An alarm 7 is installed inside the signal box 5. An air suction mechanism 3 is installed inside the first chamber 201.

[0027] The suction mechanism 3 includes a suction pump 301, an outlet pipe 302 and a suction pipe 303. The suction pump 301 is fixedly installed inside the first chamber 201. The outlet pipe 302 is fixedly installed at the output end of the suction pump 301. The outlet pipe 302 is connected to the inside of the second chamber 202. The suction pipe 303 is fixedly installed at the output end of the suction pump 301.

[0028] The suction mechanism 3 also includes a dust collection box 304 and a connector 305. The dust collection box 304 is fixedly installed at one end of the suction pipe 303. The inside of the dust collection box 304 is provided with a connector 305. The dust collection box 304 is fixedly installed on one side of the hot water boiler body 1.

[0029] The suction mechanism 3 also includes a filter plate mounting seat 306. The filter plate mounting seat 306 is inserted into the inside of the insertion groove 305, and one end of the filter plate mounting seat 306 abuts against the outer surface of the dust collection box 304.

[0030] The suction mechanism 3 also includes a connecting screw 307, and the filter plate mounting base 306 is connected to the dust collection box 304 through the connecting screw 307;

[0031] The suction mechanism 3 also includes a dustproof plate 308, and the dustproof plate 308 is fixedly installed on the inner wall of the filter plate mounting base 306.

[0032] The suction mechanism 3 also includes a connecting pipe 309 and a suction head 310. The connecting pipe 309 is fixedly installed on the lower surface of the dust collection box 304. The suction head 310 is fixedly installed at one end of the connecting pipe 309. The suction head 310 is installed on the outer surface of the hot water heater body 1 and is located above the gas connecting pipe 101.

[0033] During operation, when the water heater body 1 is working normally, the air pump 301 in the air intake mechanism 3 starts. It draws air from around the water heater body 1 through the air intake pipe 303, especially the air near the gas connection pipe 101. Because the air intake head 310 is located above the gas connection pipe 101, the air passes through the dust collection box 304 before being drawn into the air intake pipe 303. The dust collection box 304 contains a filter plate mounting seat 306 with a dustproof plate 308, which can perform preliminary dust removal and filtration on the intake air to prevent dust and other impurities from entering the subsequent detection mechanism 4. The dust collection box 304 in the suction mechanism 3 can prevent dust and other impurities from entering the detection mechanism 4, reducing the misjudgment caused by dust and other impurities in the detection mechanism 4. It also helps to extend the service life of the detection mechanism 4 and reduce equipment maintenance costs. The suction head 310 is set above the gas connection pipe 101, which can more effectively collect air samples from areas where there may be gas leaks and improve the accuracy of detection. The filter plate mounting base 306 is connected to the dust collection box 304 by the connecting screw 307, which facilitates the disassembly and replacement of the dustproof plate 308 and facilitates the maintenance and upkeep of the equipment.

[0034] After dust removal, the air enters the second chamber 202 of the housing 2 through the air outlet pipe 302. In the second chamber 202, the detection mechanism 4 detects the air to check for gas leaks. The detection mechanism 4 transmits the detection results to the controller 6 in the signal box 5. If the detection mechanism 4 detects a gas leak, the controller 6 will trigger the alarm 7 in the signal box 5 to issue an alarm signal, reminding the user of the gas leak hazard.
