[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Embodiment 1
[0028] The present utility model provides a steam generator, which can be used in various cleaning machines; it mainly includes the following structures:
[0029] This steam generator realizes the effective separation and distribution of steam by forming Chamber One 6 and Chamber Two 4 between the upper cover 9 and the lower cover 12 of the generator, and setting a steam filter plate 5 between these two chambers. Chamber One 6 is used for the accumulation of preliminary steam, while Chamber Two 4 distributes steam through the filter plate to ensure that the steam is evenly filtered and dispersed before entering Chamber Two 4, and a sealing ring 10 is set therein; the steam filter plate 5 is fixed to the lower cover 12 of the generator through the mounting posts 15, and the mounting height of the steam filter plate 5 is higher than the joint of the upper cover 9 and the lower cover 12.
[0030] The steam filter plate 5 not only blocks the direct injection of high-temperature steam, avoiding potential safety hazards, but also further refines the steam particles through the filter holes, making them evenly distributed throughout Chamber Two 4. This design greatly improves the utilization rate and uniformity of steam, ensuring that steam can be released more evenly during use, and improving the effect of cleaning or other applications.
[0031] A steam release valve 2 is set on the side of Chamber Two 4, and the steam release valve 2 is directly connected to Chamber Two 4 and the external housing. This structural design ensures that during use, users can flexibly control the release of steam, avoiding the risk of increased internal pressure caused by excessive steam accumulation.
[0032] The steam release valve 2 is not only a channel for steam output, but also controls the injection direction and speed of steam through its position and design, further improving the safety and operation convenience during use. Combining the function of the steam filter plate 5, the steam has undergone multiple buffering and filtering before injection, ensuring that the temperature and pressure of the output steam are more uniform and stable.
[0033] The generator body is provided with a water injection port 1 in the vertical direction. This design facilitates users to add water at any time during use, and the operation is convenient and fast. More importantly, a buffer wedge-shaped hole 3 is also set inside the water injection port 1. The purpose of this design is to buffer the water flow when adding water, avoiding splashing or leakage caused by too fast or too much water flow.
[0034] A water addition valve cover 8 is installed on the top of the water injection port 1;
[0035] The existence of the buffer wedge-shaped hole 3 makes the water injection process safer and more controllable, preventing damage to the internal structure caused by the impact force of water, and also avoiding the problem of the water volume exceeding the reasonable range. This design is especially suitable for users to operate when frequent water addition is required, further enhancing the use experience.
[0036] The heating tube 7 buried at the bottom of the lower cover of the generator cooperates with the thermostat 14 provided to form an accurate temperature control system. The heating tube 7 is responsible for heating water to generate steam, while the thermostat 14 automatically adjusts or cuts off the power supply when the system overheats or reaches the set temperature, ensuring that the equipment operates within a safe temperature range.
[0037] This temperature control system not only ensures the working efficiency of the steam generator, but also greatly reduces the failures and risks caused by overheating, and extends the service life of the equipment.
[0038] The heat insulation sleeve 13 wrapped around the main body of the generator has a good heat preservation effect, effectively preventing heat from dissipating outward. The application of the heat insulation sleeve 13 not only improves the energy efficiency of the equipment, but also protects the safety of users during use, preventing the risk of burns caused by overheating of the equipment shell.
[0039] At the same time, the heat insulation sleeve 13 also increases the overall durability of the equipment, enabling it to better resist external temperature changes when used in different environments, and further ensuring the stable operation of the equipment.
[0040] The steam filter plate 5 can not only be designed into circular, square or other special-shaped structures according to requirements, but also the number and distribution of the filter holes 11 can be selected according to actual applications. This diversified design enables the steam generator to adapt to different working environments and requirements, and users can select the most suitable filter plate structure according to specific application scenarios.
[0041] The filter plate is fixed to the upper cover 9 of the generator by locking bolts, ensuring the stability of the filter plate in high-temperature and high-pressure environments, avoiding loosening or displacement caused by vibration or long-term use, and further enhancing the reliability of the equipment.
[0042] Based on the above structural analysis, this steam generator demonstrates multiple significant advantages and positive effects during actual use:
[0043] Safety and reliability: Through the double-chamber design, the application of the steam filter plate 5, and the precise control of the steam release valve 2, the safety of this steam generator has been significantly improved. The filter plate effectively avoids the direct injection of high-temperature steam, while the steam release valve ensures the controllability of steam release, reducing the risk of steam accumulation.
[0044] Ease of operation: The buffer design of the water injection port 1 and the automatic adjustment of the temperature control system make the equipment easier to operate during use. Users can easily master the usage method without worrying about equipment failures or safety issues caused by improper operation.
[0045] Steam utilization efficiency: Through the porous design of the steam filter plate 5 and the reasonable distribution of Chamber II, the steam is fully utilized and evenly distributed, ensuring the high efficiency of the equipment in cleaning or other applications. At the same time, the application of the heat insulation sleeve 13 further improves the utilization rate of steam, making the equipment more energy-saving and environmentally friendly.
[0046] Multi-functional adaptability: The diverse design of the steam filter plate 5 enables the equipment to be customized according to different requirements, adapting to different working environments and operating needs, and further expanding the application scope of the equipment.
[0047] Generally speaking, the design of this steam generator fully considers the combination of safety, convenience, and high efficiency. By optimizing the structure and functions, it provides a steam generating device that performs excellently in various application scenarios. This design not only significantly improves the working efficiency but also provides users with a safer and more reliable usage experience.
