Technical Field

[0001] This utility model relates to the field of cleaning machines, and in particular to a mobile cleaning machine with a heating function. Background Technology

[0002] Traditional mobile cleaning machines mainly consist of a water tank, water pump, and cleaning gun, using high-pressure water jets for cleaning. While these devices are easy to move, in actual use, they lack heating capabilities and can only provide room-temperature water. This results in poor dissolving ability for stubborn stains such as grease and heavy oil, leading to low cleaning efficiency. Utility Model Content

[0003] In view of the shortcomings mentioned above, this utility model provides a mobile cleaning machine with heating function.

[0004] The present invention adopts the following technical solution:

[0005] A portable cleaning machine with a heating function includes a water tank, a water pump, and a cleaning gun. The water pump is mounted on the water tank and is used to draw water from the tank to the cleaning gun. The machine is characterized by further including a heating mechanism disposed between the water pump and the cleaning gun. The heating mechanism includes:

[0006] A heating housing, wherein a heating chamber is provided inside the heating housing, and the water pump and the cleaning gun are respectively connected to it;

[0007] An over-temperature protection switch is installed on the end face of the heating housing and extends into the heating cavity for temperature limiting.

[0008] An electric heating element is disposed on the end face of the heating housing and extends into the heating cavity, and its temperature sensing tube is used for heat conduction.

[0009] A rotary temperature control switch is provided on the end face of the heating housing, with its temperature sensing head inserted into the temperature measuring tube to detect the temperature, and the knob exposed.

[0010] An end cap is detachably mounted on the end face of the heating housing to protect the internal components and provides a clearance opening for the knob to extend out.

[0011] The over-temperature protection switch, the electric heating element, and the rotary temperature control switch are electrically connected to each other.

[0012] As a further improvement, the water tank is equipped with a liquid replenishment port for replenishing water.

[0013] As a further improvement, the heating housing end face is provided with a threaded ring, which is threadedly connected to the end cover.

[0017] As described above, this utility model has the following advantages compared to existing technologies: During use, the water pump draws water from the tank under negative pressure and delivers it to the heating mechanism. After being heated by the electric heating element within the mechanism, the water is supplied to the cleaning gun.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0026] As attached Figure 1As shown, a mobile cleaning machine with heating function includes a water tank 1, a water pump 2, a heating mechanism 3, and a cleaning gun 4. All components are compactly designed for easy movement and operation. The water tank 1 serves as a water storage unit. The water pump 2 is fixedly installed on top of the water tank 1 to provide high-pressure water flow. The heating mechanism 3 is located between the water pump 2 and the cleaning gun 4, which can rapidly heat the water flow, thereby improving the cleaning effect. The cleaning gun 4 is the actuating component, used to spray high-temperature, high-pressure water, suitable for cleaning oil stains and stubborn dirt. In use, the water pump 2 penetrates into the water tank 1 through a suction pipe 14, drawing water from the water tank 1 under negative pressure and delivering it to the heating mechanism 3. After heating, the water is supplied to the cleaning gun 4. This invention enhances the dissolving ability of oil stains, grease, and stubborn dirt through high-temperature, high-pressure water (especially in industrial equipment, restaurant kitchens, vehicle chassis, etc.), improving cleaning efficiency.

[0027] Furthermore, to improve energy efficiency, the heating mechanism 3 and water pump 2 are controlled by independent power supplies. Users can choose whether to activate the heating function according to actual needs. For example: Cold water mode: only water pump 2 is activated, suitable for ordinary cleaning tasks, saving energy. Hot water mode: both water pump 2 and heating mechanism 3 are activated, suitable for heavily oiled scenarios, improving decontamination capabilities. This design not only reduces energy consumption but also extends the life of the heating element, making it suitable for long-term continuous operation.

[0028] Preferably, the replenishment port 13 is located at the top of the water tank 1 for quick replenishment of clean water or cleaning agent, supporting continuous operation. The lifting trough 12 is located on the side of the water tank 1 and adopts a groove design to facilitate user handling or tilting of the water tank 1 to pour water.

[0029] As attached Figure 4 and Figure 7 As shown, the heating mechanism 3 includes a heating shell 31, an over-temperature protection switch 35, an electric heating element 36, a rotary temperature control switch 37, and an end cap 39. These components work together precisely to form a highly efficient and safe liquid heating system. The heating shell 31 serves as the basic support structure, the electric heating element 36 is the core heating element, the over-temperature protection switch 35 and the rotary temperature control switch 37 form a dual temperature control protection system, and the end cap 39 provides safety protection and convenient maintenance.

[0030] As attached Figure 1 and Figure 3As shown, the heating housing 31 is cast from high-strength aluminum alloy or stainless steel, and its interior is precision-machined to form the heating chamber 32, a key fluid channel. The heating housing 31 is equipped with a standardized water inlet 33 and a water outlet 34 that connect to the heating chamber 32. The water inlet 33 adopts a quick-release connector design for easy connection to the water pump 2 outlet. The water outlet 34 is equipped with an anti-scalding protective sleeve and is connected to the cleaning gun 4 through a high-pressure, high-temperature resistant water pipe 41. All interfaces adopt the NPT thread standard to ensure reliable sealing.

[0031] As attached Figures 3 to 5 As shown, the electric heating element 36 is located on the end face of the heating shell 31 and extends into the heating cavity 32. The electric heating element 36 is composed of a stainless steel tube, magnesium oxide powder, and a resistance wire. Specifically, a high-temperature resistance wire is evenly distributed inside the seamless stainless steel tube, and crystalline magnesium oxide powder with good thermal conductivity and insulation properties is filled in the gaps. This advanced structure results in high thermal efficiency and uniform heating. In use, current is passed through the high-temperature resistance wire, and the generated heat diffuses through the magnesium oxide powder to the surface of the metal tube, and then is transferred to the water flow, achieving the purpose of heating. It has excellent overall performance, an ultra-long lifespan, and is easy to maintain.

[0032] As attached Figures 3 to 6 As shown, the dual temperature control system consists of a rotary temperature control switch 37 (main temperature control element) and an over-temperature protection switch 35 (safety protection element) working together to ensure a safe and reliable heating process. Both switches are mounted on the end face of the heating housing 31 and form a series circuit with the electric heating element 36.

[0033] The temperature sensing tube 361, extending from the electric heating element 36, extends directly into the heating chamber 32 for heat conduction. The temperature sensing head 371 of the rotary temperature control switch 37 is precisely inserted into the temperature sensing tube 361 (H7 / p6 interference fit) to detect the temperature. During use, when the detected temperature is greater than or equal to the set value: the rotary temperature control switch 37 disconnects, stopping power supply to the electric heating element 36. When the detected temperature is less than or equal to the set value - 5℃: the pin automatically resets, re-establishing a circuit and re-supplying power to the electric heating element 36. The temperature sensing tube 361 is made of a high thermal conductivity material, specifically pure copper (thermal conductivity 401W / m·K), allowing for better heat transfer from the heating chamber 32 to the temperature sensing head 371, thus improving the detection accuracy of the temperature sensing head 371. The set value of the rotary temperature control switch 37 is mechanically adjusted via a knob.

[0034] The over-temperature protection switch 35 is inserted into the heating chamber 32 to independently detect the heating chamber temperature (set value 105℃±5℃), and adopts a manual reset structure. When the rotary temperature control switch 37 fails, the electric heating element 36 continues to work. When the temperature rises to 105℃, the over-temperature protection switch 35 forcibly disconnects the circuit, thereby stopping the power supply to the electric heating element 36. Since the system is locked in a power-off state and requires manual intervention to reset, the interruption of hot water output can be used as a fault indication signal, facilitating timely maintenance and replacement.

[0035] Furthermore, the knob-type temperature control switch 37, the electric heating element 36, and the over-temperature protection switch 35 are all fixed with stainless steel screws to prevent displacement and ensure operation. The knob-type temperature control switch 37 is fixed to the mounting post 38 on the end face of the heating housing 31 with screws, forming an overlapping effect with the electric heating element 36 and the over-temperature protection switch 35, saving installation space, reducing the size of the heating mechanism 3, and facilitating subsequent movement.

[0036] As attached Figure 2 and Figure 7 As shown, the end cap 39 is detachably mounted on the end face of the heating housing 31 via a precision threaded connection, forming a complete protection system. Specifically, a precision threaded ring 311 (M100×1.5 fine thread) is provided on the end face of the heating housing, and a matching internal thread is machined at the corresponding position on the end cap 39. The threaded ring 311 and the end cap 39 are screwed together to complete the installation of the end cap 39. This design has the following core functions: Protection function: Protects key internal components (over-temperature protection switch 35, electric heating element 36, rotary temperature control switch 37); Maintenance function: Supports quick disassembly and assembly, facilitating fault diagnosis and component replacement.

[0037] Preferably, the end cover 39 is provided with a relief opening 391 for the knob to extend out, so that the knob of the rotary temperature control switch 37 is exposed, making it easy to rotate the knob to adjust the setting value of the rotary temperature control switch 37.

[0038] In summary, during use, the water pump 2 draws water from the water tank 1 under negative pressure and delivers it to the heating mechanism 3. After being heated by the electric heating element 36 within the heating mechanism 3, the water is supplied to the cleaning gun 4. The high-temperature, high-pressure water jet is suitable for cleaning oil stains and stubborn dirt, improving cleaning efficiency. The mobile heated cleaning machine provided by this solution significantly improves cleaning efficiency through the combination of a high-pressure water pump and an intelligent heating system. Furthermore, all temperature control components are modularly installed, allowing for quick replacement by simply removing the end cap 39 during maintenance, with an average repair time of less than 15 minutes.

[0039] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
