Description

Technical Field

[0001] This utility model belongs to the field of steam structure technology for floor scrubbers, and specifically relates to a modular boiler assembly for steam floor scrubbers. Background Technology

[0002] Floor scrubbers, as cleaning equipment that integrates water rinsing, roller scrubbing, and vacuuming, are widely used in residential and commercial environments. To further improve the cleaning effect on stubborn stains such as oil and bacteria, steam-powered floor scrubbers with steam functions have appeared on the market. These floor scrubbers typically have a built-in boiler that heats the water to generate high-temperature, high-pressure steam, which is then sprayed onto the floor, using heat energy to quickly dissolve oil stains and achieve physical sterilization.

[0003] In existing steam floor scrubber designs, the boiler is typically fixedly installed inside the equipment base. Its water inlet, steam outlet, and power outlet are permanently connected to the main unit's water and electrical systems via threaded connections, quick-connect fittings, or cables. Due to water quality or environmental factors, scale easily builds up inside the boiler after prolonged use. This not only affects heating efficiency and increases energy consumption but can also clog steam channels, reducing steam output. When cleaning or replacing a boiler damaged by scale is required, the existing fixed installation method necessitates tedious disassembly work by maintenance personnel or users, including unscrewing multiple connecting pipes and disconnecting circuits. This process is not only time-consuming and labor-intensive but also prone to damaging the seals at the interfaces during repeated disassembly and reassembly, leading to secondary malfunctions such as water leaks, steam leaks, or poor contact.

[0004] Therefore, there is an urgent need in this field for an innovative boiler design for steam floor scrubbers that enables quick and convenient boiler maintenance and replacement, thereby improving the overall reliability, safety, and user experience of the product. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0006] A modular boiler assembly for a steam floor scrubber, assembled within the base of the steam floor scrubber, includes a boiler module unit detachably installed within the base and a pipe connector unit fixedly disposed within the base.

[0007] The boiler module unit includes a module base and a boiler disposed within the module base. The module base is provided with an electrical connector electrically connected to the boiler, a first water inlet connector for supplying water to the boiler, and a first steam outlet connector for outputting steam from the boiler.

[0008] The pipeline connector unit includes a connector base, which has a water inlet channel and a steam outlet channel. One end of the water inlet channel has a second water inlet connector for connecting to an external water source, and the other end has a water inlet connector that is detachably and sealingly connected to the first water inlet connector. One end of the steam outlet channel has a second steam outlet connector for outputting steam, and the other end has a steam outlet connector that is detachably and sealingly connected to the first steam outlet connector. The first water inlet connector and the water inlet connector, as well as the first steam outlet connector and the steam outlet connector, are configured to automatically align and seal when the boiler module unit is inserted into the base in an insertion direction.

[0009] In a preferred embodiment of a modular boiler assembly for a steam floor scrubber, the boiler module unit is connected to the base via a quick-release mechanism. The quick-release mechanism includes a locking member disposed on the module base, a locking groove disposed on the base and cooperating with the locking member, and an elastic element acting on the locking member to give it a locking tendency. By operating the locking member to overcome the force of the elastic element and disengage it from the locking groove, the boiler module unit can be removed from the base. The quick-release mechanism allows for easy and quick assembly and disassembly of the boiler module, greatly improving the user experience.

[0010] In a preferred embodiment of a modular boiler assembly for a steam floor scrubber, the locking element is a latch, and the module base has a groove for accommodating and sliding the latch. The elastic element is a compression spring, which acts on the latch, causing a portion to protrude from the module base and engage with the locking groove. A sliding button is fixedly connected to the latch, and the module base has a groove for the sliding button to slide. By sliding the sliding button in a direction parallel to the base surface, the latch can be driven to compress the compression spring and disengage from the locking groove. This latch and sliding button design makes operation intuitive and simple, allowing users to complete the pressing and unlocking action with one hand.

[0011] As a preferred embodiment of a modular boiler assembly for a steam floor scrubber, quick-connect sealing joints are used between the first water inlet connector and the water inlet mating connector, as well as between the first steam outlet connector and the steam outlet mating connector. The sealing connection is automatically completed without rotation or other additional actions when the module is inserted, and it is also easy and quick to remove.

[0012] As a preferred embodiment of a modular boiler assembly for a steam floor scrubber, the base has a plug-in cavity, the pipe connector unit is fixed to the bottom of the plug-in cavity, the boiler module unit can be inserted along the plug-in cavity, and each connector is aligned with the mating connector, ensuring that each connector on the module can be accurately and quickly aligned with the mating connector on the connector seat, avoiding installation difficulties or connector damage caused by misalignment.

[0013] In a preferred embodiment of a modular boiler assembly for a steam floor scrubber, the side wall of the insertion cavity is provided with a receiving groove. The receiving groove contains an electrical interface that is electrically connected to the main controller of the steam floor scrubber. When the boiler module unit is inserted into place, the electrical connector is housed within the receiving groove and electrically connected to the electrical interface. This structure prevents the wires from being pulled and damaged during assembly and disassembly, while ensuring the stability and safety of the power contact, preventing sparking or power outages caused by poor contact.

[0014] As a preferred embodiment of a modular boiler assembly for a steam floor scrubber, the boiler is a once-through boiler with a PTC heater as its heating element. The PTC heater has a self-limiting temperature characteristic, meaning it automatically reduces power when the temperature is too high, effectively preventing overheating accidents caused by dry burning of the boiler, and greatly improving the safety performance and service life of the product.

[0015] Compared with the prior art, this application has the following beneficial technical effects: by designing the boiler as a modular unit, when the boiler needs cleaning or malfunctions, users or maintenance personnel do not need to disassemble the pipes and lines, but can directly replace the entire module, which greatly simplifies the maintenance process and reduces maintenance time and costs.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] In the following embodiments, the same or similar reference numerals denote the same or similar components or components with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] In the description of this utility model, it should be understood that the terms such as center, longitudinal, transverse, length, width, thickness, upper, lower, front, back, left, right, vertical, horizontal, top, bottom, inner, outer, clockwise, and counterclockwise, indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description; therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features shown. In the description of this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] This utility model provides a modular boiler assembly for a steam floor scrubber. Its core is to integrate the boiler and its associated interfaces into an independent, quick-disassembly boiler module unit, which cooperates with the pipe joint unit fixed in the base 10 of the floor scrubber, thereby realizing convenient maintenance and replacement of the boiler.

[0032] Please see the appendix Figures 1 to 7 The modular boiler assembly is installed in the base 10 of the steam floor scrubber and mainly includes a boiler module unit and a pipe joint unit.

[0033] The boiler module unit, as a detachable core functional component, includes a molded module base 20 and a boiler built into the module base 20. The module base 20 integrates an electrical connector 21 for connecting to the boiler power cord, a first water inlet connector 22 for supplying clean water to the boiler, and a first steam outlet connector 23 for discharging the high-temperature steam generated by the boiler.

[0034] The pipeline connector unit serves as a fixed interface platform, including a connector base 30, which has an internally machined water inlet channel and a steam outlet channel. One end of the water inlet channel has a second water inlet connector 31 for connecting to the floor scrubber's water supply pipeline, and the other end has a water inlet connector 32. One end of the steam outlet channel has a second steam outlet connector 33 for connecting to the cleaning workpiece of the floor scrubber, and the other end has a steam outlet connector 34. The water inlet connector 32 and the steam outlet connector 34 are configured such that when the boiler module unit is inserted into the base 10 along a preset insertion direction, they can automatically align with the first water inlet connector 22 and the first steam outlet connector 23, respectively, and achieve a reliable sealed connection.

[0035] To enable rapid locking and releasing of the boiler module unit, a quick-release mechanism 40 is provided between the boiler module unit and the base 10. This quick-release mechanism 40 includes a locking member 41 mounted on the module base 20, a corresponding locking groove 15 mounted on the base 10, and an elastic element 42 that provides elastic preload to the locking member 41, maintaining its locking tendency. When disassembly is required, simply operate the locking member 41 to overcome the force of the elastic element 42 and disengage from the locking groove 15, allowing the entire boiler module unit to be smoothly removed from the base 10. This design makes maintenance tool-free, simple, and quick, greatly improving the user experience.

[0036] In a preferred embodiment, the quick-release mechanism 40 is implemented as follows: the locking element 41 is a latch, which is accommodated in a groove 24 on the module base 20 and can slide in a specific direction. The elastic element 42 is a compression spring, which acts on the latch, causing a portion of it to continuously protrude from the surface of the module base 20, thereby reliably engaging into the locking groove 15 of the base 10 when installed. For ease of operation, a sliding button 43 is fixedly connected to the latch, and a sliding groove 25 is provided on the module base 20 for the sliding button 43 to move. By sliding the sliding button 43 in a direction parallel to the surface of the base 10, the user can drive the latch to compress the compression spring and disengage it from the locking groove 15, thus unlocking the device. This button-type sliding unlocking method is intuitive and can be completed with one hand.

[0037] To further optimize the convenience and sealing reliability of the connection process, quick-connect sealing joints are preferably used between the first water inlet connector 22 and the water inlet mating connector 32, and between the first steam outlet connector 23 and the steam outlet mating connector 34. This type of joint automatically seals upon insertion, eliminating the need for additional steps such as rotation and tightening, ensuring sealing while achieving rapid connection and separation. To ensure precise positioning of the boiler module unit during installation, the base 10 has a plug-in cavity 12 that matches the shape of the module base 20. The pipeline connector unit is fixedly installed at the bottom of this plug-in cavity 12. When the boiler module unit is inserted along the plug-in cavity 12, all connectors on the boiler module unit can be precisely aligned with the corresponding mating connectors on the pipeline connector unit, effectively avoiding installation difficulties or damage to seals due to misalignment.

[0038] This invention also incorporates special design features for ease of use and safety in electrical connections: a receiving groove 13 is provided on the side wall of the insertion cavity 12, and an electrical interface 14 connected to the main controller circuit of the steam floor scrubber is installed within the receiving groove 13. When the boiler module unit is inserted into place, its electrical connector 21 and electrical interface 14 achieve a stable electrical connection. This built-in concealed connection structure not only avoids the pulling and wear that may occur during repeated disassembly and assembly of the wires, but also ensures stable power contact, effectively preventing the risk of arcing or power outages caused by poor contact.

[0039] In terms of boiler body selection, this utility model preferably uses a DC boiler and a PTC ceramic heater as its heating element. The PTC heater has a self-limiting temperature characteristic. When the boiler is dry-burning or the temperature rises abnormally, its resistance will increase sharply, thereby automatically reducing the output power. This can fundamentally and effectively prevent overheating accidents and greatly improve the inherent safety and service life of the product.

[0040] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
