Description

Technical Field

[0001] This utility model relates to the technical field of steam equipment accessories, specifically to a steam generator for steam equipment. Background Technology

[0002] Existing steam-type devices, such as handheld steam irons, steam cleaners, or steam mops, have steam generators with several heating chambers. Steam is ejected from several steam holes in the last heating chamber. The generated steam is quickly ejected from the steam holes in the last heating chamber, so the steam in the last heating chamber does not remain inside to form pressure. This results in discontinuous steam output from the steam generator, large fluctuations in steam volume and temperature, and a poor user experience. Utility Model Content

[0003] The purpose of this invention is to provide a steam generator for steam-type equipment, which solves the above-mentioned technical problems.

[0004] This utility model discloses a steam generator for steam-type equipment, including a body with a heating chamber, a heating element, a sealing ring, and a cover plate. The cover plate covers the upper side of the body to enclose the heating chamber. The bottom of the body has a groove, and the cover plate has an extension wall that extends downward into the groove to form a concave cavity. The concave cavity and the groove intersect to form a gas storage cavity that communicates with the heating chamber. The heating element is disposed in the body and is used to heat the water or steam in the heating chamber and the steam in the gas storage cavity. The cover plate has a water inlet pipe and a steam output pipe that can limit the steam output. The water inlet pipe is connected to the heating chamber, and the steam output pipe is connected to the gas storage cavity. The sealing ring is disposed between the cover plate and the body.

[0005] Preferably, the groove is provided with several air inlet slots that connect the heating chamber and the air storage chamber.

[0006] Preferably, the cross-section of the air intake groove is "L" shaped.

[0007] Preferably, the bottom of the body has an upwardly protruding part that divides the heating chamber into a first heating chamber and a second heating chamber, and the gas storage chamber is connected to the second heating chamber.

[0008] Preferably, the protrusion consists of an upper part and a lower part, with the heating element disposed in the lower part and the upper part being a thin wall extending upward from the lower part, the thin wall having a notch connecting the first heating cavity and the second heating cavity.

[0017] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0018] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0019] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0020] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0021] like Figures 1 to 4 As shown, this utility model discloses a steam generator for steam-type equipment, comprising a body 1 with a heating chamber, a heating element 2, a sealing ring 3, and a cover plate 4. The cover plate 4 covers the upper side of the body to enclose the heating chamber. The bottom of the body 1 has a groove 11. The cover plate 4 has an extension wall 42 that extends downward into the groove 11 to form a cavity 41. The cavity 41 intersects with the groove 11 to form a gas storage chamber that communicates with the heating chamber. The heating element 2 is disposed in the body and is used to heat the water or steam in the heating chamber and the steam in the gas storage chamber. The cover plate 4 has a water inlet pipe 43 and a steam output pipe 44 that limits the steam output. The water inlet pipe 43 communicates with the heating chamber, and the steam output pipe 44 communicates with the gas storage chamber. The sealing ring 3 is disposed between the cover plate 4 and the body 1. Compared with the prior art, this utility model has the advantages of providing an extension wall 42 on the cover plate 4 that extends downward into the groove 11 to form a cavity 41, and the cavity 41 intersects with the groove 11 to form a gas storage cavity that is connected to the heating cavity; the cover plate 4 is provided with a steam output pipe 44 that can limit the steam output and is connected to the gas storage cavity. The steam output pipe 44 limits the steam output so that the steam enters the gas storage cavity to form a certain pressure and then is output from the steam output pipe. It has the advantages of ensuring continuous steam output, less fluctuation range of steam quantity and temperature, and bringing a good user experience.

[0022] Specifically, the groove 11 has two air inlet slots 12 that connect the heating chamber and the gas storage chamber, and the air inlet slots 12 have an "L" shaped cross-section. The bottom of the body 1 has an upwardly protruding protrusion 13 that divides the heating chamber into a first heating chamber 14 and a second heating chamber 15, and the gas storage chamber and the second heating chamber 15 are connected through the air inlet slots 12. The air inlet slots 12 prevent the steam entering the gas storage chamber from easily returning to the heating chamber, thereby creating a certain pressure in the steam storage chamber.

[0023] In addition, the protrusion 13 is composed of an upper part 131 and a lower part 132. The heating element 2 is disposed in the lower part. The upper part 131 is a thin wall extending upward from the lower part 132. The thin wall is provided with a notch 133 that connects the first heating chamber and the second heating chamber.

[0024] The heating element 2 is a heating tube. The left half of the heating element 2 consists of two parallel straight tubes 21, and the right half consists of a spiral tube 22, which surrounds the first heating chamber 14. When the steam generator is installed in a steam-type equipment, the water in the heating chamber 14 can be heated by the spiral tube 22 regardless of the tilt, ensuring that the water can be continuously and stably heated and that steam can be continuously generated. This overcomes the defect of existing U-shaped heating tubes that do not surround the heating chamber, resulting in some areas where the heating chamber cannot be heated.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
