Description

Technical Field

[0001] The present application relates to the field of steam ironing machines, and in particular to a steam ironing machine boiler. Background Art

[0002] Steam ironing machine, also called hanging iron or standing iron, is a machine that can hang clothes and fabrics for ironing. Steam ironing machine uses the hot steam generated inside to continuously contact clothes and fabrics to soften the fiber structure of clothes and fabrics, and smoothes clothes and fabrics through the actions of "pulling", "pressing" and "spraying", making them as good as new.

[0003] The steam ironing machine generates steam through the internal boiler. The boiler is generally equipped with a water level probe and a temperature probe. There are two water level probes, one positive and one negative. When working, cations such as calcium and magnesium in the water will be adsorbed onto the negative electrode probe, causing calcification to adhere to the probe surface, which will quickly cause the probe to fail and the water level measurement will quickly fail. Utility Model Content

[0004] In order to increase the service life of water level measurement, the present application provides a steam ironing machine boiler.

[0005] The steam ironing machine boiler provided in this application adopts the following technical solution:

[0006] A steam ironing machine boiler comprises a boiler body and a detection mechanism; the detection mechanism comprises a water level probe; the water level probe is connected to a positive electrode; the boiler body is conductively arranged and connected to a negative electrode.

[0007] By adopting the above technical solution, the water level probe connected to the negative electrode is eliminated and replaced by a boiler body connected to the negative electrode. Cations such as calcium and magnesium in the water will be adsorbed on the inner wall of the boiler body, and the surface area of ​​the inner wall of the boiler body is much larger than the surface area of ​​the water level probe, thereby improving the service life of the water level measurement.

[0008] Optionally, the detection mechanism also includes a conductive shell; the conductive shell passes through the upper side wall of the boiler body and extends into the boiler body; the water level probe is located outside the boiler body and is conductively arranged between the conductive shell; and the conductive shell and the boiler body are insulated.

[0009] By adopting the above technical solution, the water level probe is located outside the boiler body and detects the water level by conducting electricity through the conductive shell extending into the boiler body. In this way, the water level probe is easy to repair and replace, thereby increasing the overall service life of the boiler.

[0010] Optionally, the detection mechanism further includes a temperature measuring component; the temperature measuring component includes a thermistor and a pair of signal lines respectively connected to two ends of the thermistor; the thermistor is located at the bottom of the conductive shell.

[0011] By adopting the above technical solution, water level detection and water temperature measurement are combined together, so that only one hole needs to be processed on the boiler body for installation, which saves processing costs and improves reliability.

[0012] Optionally, a U-shaped, heat-conductive, temperature measuring component placement tube is provided in the conductive shell; the temperature measuring component is located in the temperature measuring component placement tube and the thermistor is located at the bottom of the temperature measuring component placement tube; a heat-conductive sealant is provided at the bottom of the conductive shell; the heat-conductive sealant fills the bottom space of the conductive shell outside the bottom of the temperature measuring component placement tube.

[0013] By adopting the above technical solution, the thermal conductive sealant increases the heat conduction speed and improves the measurement accuracy of the temperature measuring component. At the same time, the temperature measuring component is located in the temperature measuring component placement tube, which is beneficial to improve the protection of the thermistor.

[0014] Optionally, an insulating sealing silicone sleeve is provided between the conductive shell and the boiler body.

[0015] By adopting the above technical solution, the presence of insulating sealing silicone avoids short circuit between the conductive shell and the boiler body, thereby improving the safety of use.

[0016] Optionally, it also includes a calcification adsorption mechanism; the calcification adsorption mechanism is detachably mounted on the boiler body; the calcification adsorption mechanism includes a calcification collection rod inserted into the boiler body; the calcification collection rod is made of a conductive material; and a conductive arrangement is provided between the calcification collection rod and the boiler body.

[0017] By adopting the above technical solution, the calcification collecting rod is connected to the boiler body, so that the calcification is preferentially attached to the calcification collecting rod, which reduces the possibility of the calcification adhering to the inner wall of the boiler body and improves the service life of the boiler body; at the same time, since the calcification adsorption mechanism is detachable, it is convenient to clean or replace the calcification collecting rod.

[0018] Optionally, a connecting pipe is formed on the side wall of the boiler body; the connecting pipe is made of a conductive material; the calcification adsorption mechanism also includes a connecting assembly; the connecting assembly includes a connecting column made of a conductive metal and a handle fixed at one end of the connecting column; the handle is made of an insulating material; the other end of the connecting column is inserted into and screwed into an end of the connecting pipe away from the boiler body; the calcification collecting rod is inserted into an end of the connecting column away from the handle.

[0019] By adopting the above technical solution, the calcification adsorption mechanism is connected to the connecting pipe by screw connection through the connecting column, which has a simple structure and is easy to disassemble and assemble.

[0020] Optionally, a sealing ring is provided between the connecting column and the connecting pipe.

[0021] By adopting the above technical solution, the presence of the sealing ring increases the sealing performance and reduces the possibility of water leakage.

[0022] Optionally, the handle is made of plastic.

[0023] By adopting the above technical solution, the overall mass of the connection assembly is reduced, and at the same time, the processing is convenient and the service life is long.

[0024] Optionally, the calcification collecting rod is a stainless steel rod with a mesh pattern formed on the cylindrical surface.

[0025] By adopting the above technical solution, the presence of the mesh pattern improves the adhesion of the calcification and reduces the possibility of the calcification falling from the calcification collecting rod, thereby improving the cleaning efficiency.

[0026] In summary, the beneficial effects of this application are:

[0027] 1. The water level probe connected to the negative electrode is cancelled and replaced by the boiler body connected to the negative electrode. The cations such as calcium and magnesium in the water will be adsorbed on the inner wall of the boiler body. The surface area of ​​the inner wall of the boiler body is much larger than that of the water level probe, thereby increasing the service life of the water level measurement.

[0028] 2. The water level detection and water temperature measurement are combined together, and only one hole needs to be processed on the boiler body for installation, which saves processing costs and improves reliability. BRIEF DESCRIPTION OF THE DRAWINGS
