Description

Technical Field

[0001] The utility model relates to the technical field of electric irons, in particular to an electric iron with a novel protective structure. Background Art

[0002] Electric irons are cleaning appliances that use electric heat to iron clothes. They are one of the indispensable appliances in modern families and are tools for smoothing clothes and fabrics. The power is generally between 300-1000W. Its types can be divided into: ordinary type, temperature-controlled type, steam type, neat spray type, etc. Electric irons are made using the thermal effect of electric current and are used to iron clothes. Electric irons have a simple structure, are easy to manufacture and easy to use, and therefore have developed rapidly. The most produced and used electric irons are ordinary type and ordinary temperature-controlled type. There are also new varieties of electric irons such as jet type, spray type, constant temperature type and electrolytic steam type. High power, light weight, automatic temperature control, steam or spray, and the pursuit of beautiful appearance are the development direction of the new generation of electric irons.

[0003] After searching, the patent announcement number CN214831358U discloses a protective intelligent electric iron with an automatic power-off function, comprising a main body, a bottom plate is arranged at the bottom end of the main body, a plate sleeve is arranged outside the bottom plate, a docking block is arranged on the inner surface wall of the plate sleeve, a docking groove is opened outside the docking block and on the outer surface wall of the bottom plate, a fixing block is arranged on the outer surface wall of the bottom plate, a spring is arranged on the inner wall of the fixing block, a clamping block is arranged at one end of the spring, a clamping groove is opened outside the clamping block and on the inner wall of the plate sleeve, and a block groove is opened on the side wall of the fixing block; the protective intelligent electric iron with an automatic power-off function can effectively protect the bottom plate by arranging the plate sleeve, the docking block, the docking groove, the fixing block, the spring, the clamping block, the clamping groove, the block groove and the pulling block, so as to avoid the problem that the fluff on the clothes or fabrics adheres to the bottom plate and causes the air outlet to be blocked, thereby making the electric iron unusable, and effectively reducing the number of times the bottom plate is replaced.

[0004] In actual use, when the existing electric iron is used for ironing, the soleplate of the electric iron has a certain high temperature. When the electric iron is not in use, the user generally puts the electric iron in a cubic shape. When the electric iron falls over or the user forgets to turn off the electric iron and the soleplate of the electric iron is still in contact with an object, a fire may occur between the high temperature on the soleplate of the electric iron and the object in contact with it, which has low safety. Therefore, we propose an electric iron with a new protective structure to solve the existing problems. Utility Model Content

[0005] The purpose of the utility model is to provide an electric iron with a novel protective structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric iron with a novel protective structure comprises a heating base plate, protrusions are installed on the upper sides of the outer walls of the heating base plate, the protrusions are installed on the lower surface of the insulation board, a water tank is installed at the center of the upper surface of the insulation board, a sound and light alarm is installed on one side of the upper surface of the water tank, smoke detection sensors are installed on both sides of the upper surface of the insulation board, a water outlet pipe is arranged at the bottom end of the water tank, the bottom end of the water outlet pipe passes through the surface of the insulation board and the top end of the heating base plate in turn, extends into the cavity and is connected to the water inlet pipe through a pipe joint, the water inlet pipe is arranged at the top end of the hollow rectangular plate, a flow equalizing hole is opened at the bottom of the hollow rectangular plate, and the hollow rectangular plate is connected to the top end of the cavity through a connecting rod.

[0007] When the electric iron falls over or the user forgets to turn off the electric iron and the soleplate of the electric iron is still in contact with an object and a fire occurs, a certain amount of smoke will be generated before the fire occurs. The smoke detection sensor detects in real time whether there is smoke around the utility model. When the smoke detection sensor detects smoke, the controller controls the solenoid valve on the water outlet pipe to open, and the water inside the water tank flows into the hollow rectangular plate.

The water in the cavity is discharged from the steam discharge hole, which can effectively extinguish the fire generated at the contact point between the heating soleplate and the object, so that the utility model can effectively prevent the heating soleplate from burning without being heated. When ironing, the heating base plate itself has a high temperature and objects in contact with it may catch fire, which improves safety. Through the coordinated arrangement of the hollow rectangular plate, the flow equalizing hole and other structures, the flow equalizing hole can evenly flow the flowing water, so that the water can flow evenly into the cavity and be discharged from the steam discharge hole, thereby avoiding the situation where the local contact between the heating base plate and the object cannot be effectively extinguished, causing the fire to continue to spread. Through the arrangement of the sound and light alarm, when the smoke detection sensor detects the generation of smoke, the controller controls the sound and light alarm to sound and light alarm, reminding the surrounding people to perform fire extinguishing operations, thereby further improving safety.

When the electric iron falls over or the user forgets to turn off the electric iron and the soleplate of the electric iron is still in contact with an object and a fire occurs, a certain amount of smoke will be generated before the fire occurs. The smoke detection sensor detects in real time whether there is smoke around the utility model. When the smoke detection sensor detects smoke, the controller controls the solenoid valve on the water outlet pipe to open, and the water inside the water tank flows into the hollow rectangular plate. The water in the hollow rectangular plate is discharged from the flow-equalizing hole into the cavity. The water in the cavity is discharged from the steam discharge hole, which can effectively extinguish the fire generated at the contact point between the heating soleplate and the object. Therefore, the utility model can effectively prevent the heating soleplate from causing a fire when the heating soleplate itself is not used for ironing and the object in contact with it is still at high temperature, thereby improving safety.

[0018] 2. The utility model adopts the coordinated arrangement of the hollow rectangular plate, the flow equalizing hole and other structures. The flow equalizing hole can play a role in equalizing the flowing water, so that the water can flow evenly into the cavity and be discharged from the steam discharge hole, thereby avoiding the situation where the local contact between the heating base plate and the object cannot be effectively extinguished, resulting in the fire continuing to spread.
