Description

Technical Field

[0001] The utility model relates to the technical field of cleaning steam generators, and more specifically to a steam generator. Background Art

[0002] With the improvement of people's living standards and quality, higher requirements are placed on the quality of the living environment, and a new cleaning tool, the housewife's steam cleaning machine, has emerged.

[0003] Steam cleaning machines use high-temperature, high-pressure steam to clean floors, doors, windows, clothing, range hoods, air conditioners, microwave ovens, and sanitary ware to sterilize surfaces, remove dust and bacteria, and are environmentally friendly and hygienic. They can prevent allergies and remove stubborn stains and oil stains. No chemical reagents are required, and there is almost no damage to the cleaned items. While people enjoy a scientific and hygienic environment, they will not cause secondary pollution to the environment.

[0004] The working principle of the steam cleaner is to accelerate the movement speed of the molecules on the dirt surface through the high-temperature steam, and to destroy the binding force between them to achieve the purpose of removing various stubborn stains. The special steam generation system with a water pump can quickly convert clean water into high-temperature and high-pressure strong steam within 30 seconds. Among them, the steam generator is the key component of the steam cleaner, which directly affects the user experience.

[0005] Most of the existing steam generators have only a single vaporization chamber, some of which are straight-through vaporization chambers, and some are bent vaporization chambers or labyrinth vaporization chambers formed by partitions. However, no matter what kind of steam generator, there are the following defects: when there is a lack of water at the end of use or during use, water injection is required. The steam generator is still in a high temperature state. If the user suddenly injects cold water to heat it, high-temperature steam will be generated. The high-temperature steam will instantly spray out from the mouth of the pot, which will cause serious scalding accidents; another defect is that if the water is added beyond the rated capacity, it will cause water spraying during use, which greatly reduces the experience and causes trouble to consumers.

[0024] Embodiment 1

[0025] The present utility model provides a steam generator, which can be used in various cleaning machines; it mainly includes the following structures:

[0026] The threaded connection structure of the steam filter pipe 4 and the water injection port 1:

[0027] This steam generator forms an innovative steam treatment structure by opening a water injection port 1 in the vertical direction of the generator main body and arranging a steam filter pipe 4 inward along the water injection port 1. One end of the steam filter pipe 4 is provided with internal and external threads (the internal and external threads are collectively called the steam filter pipe thread 3). The external thread is threadedly connected to the inner shell of the water injection port 1, and the internal thread is tightly connected to the water adding valve cover 9. This double-thread design not only ensures the stability of the steam filter pipe 4, but also facilitates disassembly and maintenance, increasing the service life of the equipment.

[0028] At the same time, in order to prevent the mutual influence of the double threads during the fastening process, the pitch of the external and internal threads can be adjusted to adjust the force required for tightening and loosening, or other methods can be used to change this situation.

[0029] This threaded connection structure can effectively prevent the direct injection of steam, thereby reducing the risk of instantaneous steam ejection and protecting users from burns by high-temperature steam. The principle is that after injecting liquid along the water injection port 1, the liquid vaporizes, and the steam gushing will first move in the chamber. The steam filter pipe 4 will block part of the steam from directly ejecting, and a small amount of steam flowing into the filter pipe will be blocked by the subsequent injected liquid, avoiding direct steam injection;

[0030] Meanwhile, this design makes the installation and replacement of the steam filter pipe 4 more convenient, contributing to the quickness of the maintenance process.

[0031] Adjustability of the length of the steam filter pipe 4:

[0032] The length of the steam filter pipe 4 is set according to the rated water level line 7, enabling it to be adjusted according to different usage requirements. The core of this design is that when a large amount of water needs to be added, the steam filter pipe 4 can be set shorter to maximize the use of the internal space; while when less water needs to be added, the steam filter pipe 4 can be set longer to limit the addition of excess water.

[0033] This length adjustability not only enhances the applicability of the steam generator, meeting different requirements for the amount of water added in different scenarios, but also reduces the excessive generation of steam by limiting the amount of water added, thus avoiding the danger of steam jetting out from the kettle mouth instantaneously.

[0034] Structural optimization of the generator body:

[0035] The generator body includes an upper cover 10, a lower cover 13, and a sealing ring 12. By setting the sealing ring 12 between the upper and lower covers and fixing it with locking bolts 11, the sealing of the internal chamber is ensured. This sealing structure not only improves the durability and safety of the equipment, but also effectively prevents steam leakage and improves the utilization efficiency of steam.

[0036] The rated water level scale line set on the side wall of the generator upper cover 10 further enhances the operation convenience. Users can intuitively adjust the water level according to the scale line, avoiding affecting the generation and use of steam due to excessive or insufficient water addition.

[0037] Dual-chamber design and steam release valve:

[0038] A chamber one 14 is formed between the upper cover and the lower cover of the generator. A chamber two 6 is formed by connecting the protruding structure on the upper cover with the chamber one. A steam release valve 2 is provided on the side of the chamber two 6. This dual-chamber design helps to effectively disperse steam, avoiding the concentrated jet of high-temperature steam and further improving the safety of the equipment.

[0039] The setting of the steam release valve 2 enables the control of the steam discharge amount and direction during use, reducing the safety hazards caused by excessive steam accumulation and providing higher operation flexibility for users.

[0040] Safety design of the bottom structure:

[0041] A heating tube 8 is buried at the bottom of the generator lower cover 13, and a thermostat 15 and a steam outlet are also provided. This bottom structure optimizes the heating and steam outlet paths, enabling the steam generator to quickly heat up and generate stable steam output in a short time.

[0042] The setting of the thermostat 15 ensures that the device can automatically cut off power or adjust power when overheating, greatly improving the safety of the device and preventing accidents caused by excessive temperature.

[0043] Application of the heat insulation sleeve 16:

[0044] By equipping the generator body with the heat insulation sleeve 16, the leakage of heat is effectively prevented, and the energy efficiency of the steam generator is improved. At the same time, the heat insulation sleeve 16 can also prevent scalding caused by excessive temperature of the outer shell, further protecting the safety of users.

[0045] The design of this steam generator shows multiple advantages during use:

[0046] Enhanced safety: Through the threaded connection of the steam filter pipe 4, the double-chamber design, and the setting of the steam release valve, the direct injection of high-temperature steam is effectively prevented, reducing the risk of scalding to users during use. At the same time, the setting of the sealing ring 12 and the thermostat 15 ensures the stability and safety of the device during high-temperature operation.

[0047] Improved operational convenience: The adjustable design of the steam filter pipe 4 and the clear water level scale make it convenient for users to adjust the water addition amount, so as to flexibly meet different usage requirements. The threaded connection design also simplifies the maintenance and operation process of the device.

[0048] Enhanced energy efficiency: The application of the heat insulation sleeve 16 and the buried bottom of the heating tube not only improve the heating efficiency of the steam generator, but also reduce heat dissipation, further improving the overall energy efficiency of the device and saving energy consumption.

[0049] Versatility: By integrating multiple functions in a compact design, this steam generator is not only suitable for steam requirements in various occasions, but also can meet different usage environments and requirements through simple operation adjustments.

[0050] Generally speaking, the structural design of this steam generator fully considers the balance of safety, operational convenience, and energy efficiency, providing users with an efficient, safe, and easy-to-operate steam generation device. This design has significant improvements and enhancements compared to traditional technologies, and can bring a better user experience and higher work efficiency in actual use.
