After the water injection switch is turned on, water can be injected through the water injection switch. The water pipe and the upright pipe flow into the pot, and the heating is continued after the water injection switch is turned off. When the water level of the boiling water in the pot is lowered below the new magnetic reed switch position, the buzzer will sound again. .

Description

Water level warning device in pot with magnetic reed switch

The invention relates to a water level warning device in a pot with a magnetic reed switch, in particular to a pot that can be adjusted to the length under the water surface of the pot by adjusting the upright tube assembly with the magnetic reed switch without opening the lid, so that the boiling water in the pot Adjustable designated water level device that causes the buzzer to sound.

The applicant has developed a siren device for boiling water at an adjustable specified water level (ROC New Patent No. M439872), which can set the steam generated by boiling water when the boiling water level is lowered to the specified level without opening the lid. Only the whistle can flow out through the whistle.

However, the inner diameter of the steam inlet of the conventionally known boiling water sirens device with adjustable water level (ROC New Patent No. M439872) is relatively small. Smaller, causing users to be unable to hear the warning of the whistle, although the applicant has continued to develop a boiling water sounder with an auxiliary buzzer (ROC New Patent No. M557079), the steam generated by boiling water The upward flow flows out through the whistle above the steam guide mechanism, which causes the whistle to sound, and the buzzer can be triggered to sound, but the internal diameter of the steam inlet is relatively small, so the amount of steam flowing into the steam guide pipe may be upward. Not enough to trigger the buzzer.

Therefore, in view of the foregoing, the inventor of the present invention considered and designed a magnetic reed switch The water level warning device in the pot is intended to improve the lack of existing technology, thereby enhancing the industrial implementation and utilization.

In view of the foregoing shortcomings of the prior art, the present invention is to design a water level warning device in a pot with a magnetic reed switch with patent elements such as novelty, progress, and industrial applicability, in order to overcome the difficulties of the prior art.

In order to achieve the above object, the technical means adopted by the present invention is to design a water level warning device in a pot with a magnetic reed switch, which mainly includes a straight pipe assembly and a fixed seat lid mechanism; the vertical pipe assembly is external Draw a vertical tube with a length scale, a tee connected to the upper end of the vertical tube, a fixed nut connected to the upper end of the tee, a circuit tube located inside the vertical tube, and a tube located below the vertical tube. It consists of a floating magnet holder, a retaining ring located below the floating magnet holder, a leak-proof ring connected to the side end of the tee, an L-shaped water pipe, a buzzer assembly and a water injection switch; the circuit tube The upper end is locked to the fixed nut and penetrates into the upright pipe. The internal structure mainly includes a magnetic reed switch, a positive wire and a negative wire; the floating magnet holder has a ring magnet; the buzzer The assembly is fixed between the water pipe and the water injection switch, and mainly contains a support seat, a buzzer circuit switch, a buzzer and a battery; the fixed seat pot cover mechanism is a pot perforated at the center Cover It consists of a fixed ring installed in the center hole of the pot lid, a fixed knob installed in the hole in the upper half of the fixed ring, and a fixed nut installed in the lower half of the fixed ring. Lock into the upper end of the upright pipe, then lock the fixed nut into the upper end of the tee, put the circuit tube into the upright pipe and lock its upper end inside the fixed nut, in addition, the leakproof ring After being placed on the side of the tee, the side end of the L-shaped aqueduct is locked into the side of the tee, and the support seat of the buzzer assembly is placed on the water guide. The water injection switch is locked into the upper end of the aqueduct through a circular hole passing through the support base above the support base, and the buzzer circuit switch, the buzzer and the battery are respectively placed on the support base Set the installation position and complete the connection of the corresponding lines, and connect the positive wire and the negative wire at the upper end of the circuit tube to the buzzer circuit switch and the battery respectively; then, place the fixing ring in the center of the lid Attach the perforation at the lower end of the fixing ring with the fixing nut to connect the fixing ring to the pot lid, and install the fixing knob at the perforation in the upper half of the fixing ring to complete the fixed pot. The combination of the lid mechanism; finally, after the fixed knob on the fixed pot lid mechanism is loosened, the upright tube assembly is put into the perforation at the center of the lid of the fixed pot lid mechanism, and then the floating The magnet seat is sheathed outside the circuit tube, and the buckle ring is inserted into the circuit tube to prevent the floating magnet seat from falling. Then, the magnetic reed switch is positioned at a preset level of the buzzer sounding water level below the water surface. Then lock the fixed knob, this The floating magnet holder floats due to the influence of buoyancy, so the buzzer does not sound after the buzzer circuit switch is turned on, but the boiling water level in the pot is lowered to the preset buzzer when the heating is continued. When the ringing water level is below, the floating magnet seat is lowered to the same level as the reed switch because of no buoyancy, so the magnetic reed switch is turned on by the magnetic force of the internal magnet of the floating magnet seat, causing the buzzer to sound. At this time, you can repeat the above process and refer to the relative position of the length scale drawn on the upright tube to reset the new reed switch position, causing the floating magnet seat to rise due to buoyancy and open the reed switch. Therefore, the buzzer will stop ringing, and depending on the use requirements, a funnel is placed on the upper end of the water injection switch. After the water injection switch is turned on, water can be injected into the pot through the water pipe and the upright pipe, and the valve is closed. After the water injection switch continues to heat, the buzzer will sound again when the boiling water level in the pot is lowered below the new magnetic reed switch position.

The water level warning device in a pot with a magnetic reed switch according to the present invention uses a The combination of the upright pipe assembly and a fixed seat pot lid mechanism can adjust the buzzer sounding water level setting without opening the pot lid, and the relative position of the length scale and the reed switch on the outside of the upright pipe, The position of the magnetic reed switch can be estimated without opening the lid, that is, the set buzzer sounds the water level value. In addition, the water pipe and the water injection pipe connected by the side ends of the three-way pipe of the upright pipe assembly When the buzzer sounds, a switch can be used to place a funnel on the top of the water injection switch according to the use requirements. After the water injection switch is turned on, water can be injected into the pot through the water guide pipe and the upright pipe, and the water injection switch is turned off. After the heating is continued, the buzzer will sound again when the water surface of the boiling water in the pot is lowered below the position of the new magnetic reed switch. In order to make the above purpose, technical characteristics and gain after actual implementation It is more obvious and easy to understand.
