Detailed Implementation

[0031] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of the utility model protection.

[0032] The following will be combined with the drawings in the embodiments of the utility model, Figures 1-8 The application is further described in detail,

[0033] The embodiment of the application discloses a structure of a steam heater of a floor cleaning machine, which comprises a die casting 1, an automatic reset temperature controller 8 and a buckle slot 14. The upper and lower ends of the die casting 1 are respectively provided with mounting ears 18 with mounting holes 17. The mounting ears 18 provide a convenient mounting mode, and the heater can be fixed on the floor cleaning machine or other equipment through screws 15, so that the mounting process is simplified.

[0034] The left side of the die casting 1 is provided with two plug-in pieces 5 electrically connected with two terminal pieces 13A parallel to the outgoing line, and the two plug-in pieces 5 are electrically connected with the heating tube 2 extending into the die casting 1. The outer end of the heating tube 2 is sleeved with a silica gel sleeve 4. The silica gel sleeve 4 can protect the outer end of the heating tube 2 from being damaged, especially during installation and transportation. The silica gel has good insulation performance, and can further improve the safety performance of the heating tube 2. The silica gel sleeve 4 can usually withstand high temperature and will not be damaged due to the temperature rise of the heating tube 2. The silica gel sleeve 4 can also provide a more beautiful appearance and increase the overall quality of the product.

[0035] The die casting 1 is provided with a water pipe 3 penetrating through the die casting 1 and coiled in a straight slot shape. The terminal piece 13A at the upper end is electrically connected to the wire assembly A 6, and the terminal piece 13A at the lower end is electrically connected to the wire assembly B 7.

[0036] The water pipe 3 is made of 304 stainless steel. The plug-in piece is made of nickel-plated material, and the heating tube 2 is a copper-plated iron pipe. The 304 stainless steel has excellent corrosion resistance and is suitable for use in various environments, especially in humid and chemical contact environments. The stainless steel water pipe 3 can withstand high temperature and is suitable for the working environment of the steam heater. The surface of the stainless steel material is smooth, and bacteria and dirt are not easy to adhere, which is beneficial to keep the water clean. Nickel plating and copper plating can improve the wear resistance of the plug-in piece and the heating tube 2, and prolong the service life. Nickel plating and copper plating can improve the electrical conductivity of the material and ensure the stability of the circuit connection. After nickel plating and copper plating treatment, the surface of the material is brighter, and the appearance of the product is improved.

[0037] The automatic reset temperature controller 8 is fixed on the right side of the die casting 1 by the screw 15, and the two terminal sheets 13B electrically connected to the automatic reset temperature controller 8 are respectively electrically connected to the wire assembly B7 and the wire assembly C12;

[0038] The water pipe 3 in the form of a straight slot is arranged inside the die casting 1, which makes the heater structure more compact, saves installation space, and improves the overall aesthetics. The automatic reset temperature controller 8 can automatically cut off power when the temperature abnormally rises, preventing the heater from overheating and increasing the safety of use. The design of the plug-in sheet 5 makes the electrical connection between the heating tube 2 and the die casting 1 more convenient, and the screw 15 fixing method of the automatic reset temperature controller 8 is also convenient for installation and replacement. The electrical connection mode of the terminal sheet 13 ensures the stability and reliability of the circuit connection, reducing the failure caused by poor contact.

[0039] The buckle slot 14 is integrally formed on the right side of the die casting 1, and the installation area of the wire assembly A6 is fixed in the buckle slot 14 by the pressing sheet 10, and the pressing sheet 10 is screwed on the buckle slot 14 by the screw 9. Using the screw 9 to screw the pressing sheet 10 can provide a more stable fixing method, preventing the pressing sheet 10 from loosening due to vibration during equipment operation. If the pressing sheet 10 needs to be replaced or maintained, the screw 9 screwing method makes the process more convenient and fast. The surface of the buckle slot 14 is bonded with a PI insulating film, and the PI insulating film is coated with a layer of thermal conductive silicone grease. The PI (polyimide) insulating film has good electrical insulation performance and can prevent electrical short circuit. The thermal conductive silicone grease layer can improve the heat conduction efficiency of the wire assembly A6, helping to quickly transfer the heat generated by the wire assembly A6 to other parts of the heater. The PI insulating film can also protect the buckle slot 14 from the influence of the external environment, such as preventing corrosion and wear.

[0040] The outside of the installation area of the wire assembly A6 is sleeved with a ferrotron sleeve 16; the two ends of the ferrotron sleeve 16 are treated with double-wall heat shrink tube sealing and are symmetrically distributed at both ends of the installation area. Double-wall heat shrink tube sealing can improve the waterproof and moisture-proof performance of the wire assembly, avoiding short circuit and corrosion problems caused by water intrusion. The heat shrink tube has good electrical insulation performance and can protect the wire assembly from electric leakage. Double-wall heat shrink tube sealing can make the two ends of the wire assembly symmetrically distributed, which helps to maintain the stability and aesthetics of the entire structure.

[0041] The buckle slot 14 is integrally formed on the right side of the die casting 1, which helps to improve the overall strength and stability of the structure, and also simplifies the production process. The wire assembly A6 is fixed in the buckle slot 14 by the pressing sheet 10, which is more fixed and reduces the risk of loosening and falling caused by external factors such as vibration.

[0042] The mounting area of the wire assembly A6 is sleeved with a ferroton sleeve 16 outside. The ferroton sleeve 16 has good heat resistance and insulation performance, which can protect the wire assembly from the influence of the external environment (such as high temperature, humidity, etc.), and further improve the safety and reliability of the circuit.

[0043] The wire length of the wire assembly A6 is 650 mm, the wire length of the wire assembly C12 is 700 mm, and the wire length of the wire assembly B7 is 140 mm. The right side of the die casting 1 is also connected with a grounding wire assembly 11, and the wire length of the grounding wire assembly 11 is 750 mm. The length of the die casting 1 is 76.5-78 mm, the height is 60-60.5 mm, and the width is 28-28.2 mm. Different lengths of wire assemblies can meet different installation needs, so that the heater can be flexibly installed at different positions on the scrubber, and maintenance and replacement are also facilitated. The die casting 1 has small volume and small heat capacity, so it can quickly heat up when heating, and the speed of generating steam is correspondingly accelerated. Although the die casting 1 has small volume, a well-designed heater can generate a large amount of steam while ensuring rapid heating, improving work efficiency. The small volume of the die casting 1 makes the entire heater more compact, saving space and facilitating installation on scrubbers and other equipment.

[0044] The structure of the steam heater of the scrubber heats water through the straight slot-shaped coiled water pipe 3 inside the die casting 1 to generate steam. The mounting ears 18 on the die casting 1 are fixed on the scrubber through screws 15, ensuring the stability of the heater. The heating tube 2 is electrically connected with the plug-in sheet 5, and is connected with the wire assembly through the terminal sheet 13, realizing the closure of the circuit, so that the heating tube 2 can be heated. The automatic reset temperature controller 8 monitors the temperature to ensure that the heater works within a safe temperature range. This design simplifies the installation process and improves the convenience of installation; at the same time, through the compact structure design, the installation space is saved, so that the heater can be flexibly installed at different positions of the scrubber.

[0045] The silica gel sleeve 4 at the outer end of the heating tube 2 provides good insulation protection, preventing the heating tube 2 from being damaged. The application of the water pipe 3 made of 304 stainless steel and the heating tube 2 plated with nickel and copper, as well as the PI insulation film and the heat-conducting silicone grease layer, all improve the heat resistance, corrosion resistance and electrical insulation performance of the heater. The working safety of the heater is improved, the electrical short circuit and corrosion are prevented, the long-term stable operation of the heater is ensured, and the overall texture of the product is improved.

[0046] The design of the buckle slot 14 being integrally formed enhances the structural strength of the right side of the die casting 1. The wire assembly A6 is fixed in the buckle slot 14 by the pressing sheet 10 and is fixed by screw 9, ensuring the stability of the connection. The Teflon sleeve 16 and double-walled heat shrink tube sealing treatment provide waterproof and moisture-proof protection for the wire assembly. This design reduces the risk of wire assembly loosening and falling off due to vibration and other reasons, improves the stability and reliability of the circuit connection, and avoids short circuit and corrosion problems caused by moisture intrusion.

[0047] The die casting 1 has a small volume and a small heat capacity, allowing for rapid heating and fast steam generation, improving heating efficiency. Different lengths of wire assemblies meet different installation needs, and the connection of the ground wire assembly 11 further improves safety. Rapid heating means that the scrubber can start working faster, improving cleaning efficiency. The compact design saves space, making the heater more suitable for various scrubber equipment, and also facilitating maintenance and replacement.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features, as long as they are within the spirit and principles of the present application.
