[0031] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the following embodiments are combined with the drawings to specifically describe the present application. And define the direction from top to bottom shown in the paper as the direction from top to bottom in the present embodiment. Figure 7

[0032] Referring to Figures 1 to 7 The double water inlet double cavity independent temperature control type steam boiler provided by the present embodiment includes:

[0033] The main body 1 is internally formed with two upper and lower arranged and isolated upper vaporization cavity 7 and lower vaporization cavity 8, and the main body 1 is provided with first heating body 23 for controlling the vaporization temperature in the upper vaporization cavity 7, and second heating body 24 for controlling the vaporization temperature in the lower vaporization cavity 8;

[0034] And, the main body 1 is further formed with first liquid inlet 3 communicated to the upper vaporization cavity 7, and second liquid inlet 4 communicated to the lower vaporization cavity 8, respectively for injecting liquid flow into the upper vaporization cavity 7 and the lower vaporization cavity 8; The outer wall of the main body 1 is further formed with at least one first steam outlet 14 communicated to the upper vaporization cavity 7, and at least one second steam outlet 15 communicated to the lower vaporization cavity 8, respectively for flowing out the steam in the upper vaporization cavity 7 and the lower vaporization cavity 8.

[0035] Based on the above technical scheme, the double water inlet double cavity independent temperature control type steam boiler includes the main body 1, the main body 1 is provided with the upper vaporization cavity 7, the lower vaporization cavity 8, the first heating body 23, the second heating body 24, the first steam outlet 14, the second steam outlet 15, the first liquid inlet 3, the second liquid inlet 4, so that the purpose of double water inlet double cavity and independent temperature control can be realized, and the vaporization degree in the vaporization cavity can be effectively improved.

[0036] In a preferred embodiment, as shown in Figures 3 to 5 The main body 1 includes upper furnace body 5 and lower furnace body 6 which are spliced together, the upper vaporization cavity 7 is formed in the upper furnace body 5, and the lower vaporization cavity 8 is formed between the lower furnace body 6 and the upper furnace body 5. Further, the upper furnace body 5 is open at the top and detachably assembled with an end cover 2, the end cover 2 is provided with a first liquid inlet 3 and a second liquid inlet 4, the upper furnace body 5 is formed with a flow guide through hole 11 communicated to the lower vaporization cavity 8 and the second liquid inlet 4, and the first liquid inlet 3 is assembled with a first liquid inlet assembly 25, and the second liquid inlet 4 is assembled with a second liquid inlet assembly 26. ​

[0037] As a further preferred embodiment, the first labyrinth flow channel 21 is formed by the plurality of first partitioning ribs 19 in the upper vaporization cavity 7, and the first liquid inlet 3 is adjacent to the starting position of the first labyrinth flow channel 21 and the first steam outlet 14 is adjacent to the ending position of the first labyrinth flow channel 21. Further, the second labyrinth flow channel 22 is formed by the plurality of second partitioning ribs 20 in the lower vaporization cavity 8, and the second liquid inlet 4 is adjacent to the starting position of the second labyrinth flow channel 22 and the second steam outlet 15 is adjacent to the ending position of the second labyrinth flow channel 22. The labyrinth flow channel can effectively increase the vaporization time of the liquid flow in the vaporization cavity, so that the steam flowing out of the steam outlet has a higher vaporization degree.

[0038] As a further preferred embodiment, the starting position of the second labyrinth flow channel 22 is further upwardly protruded to form a tapered column 27, which serves to guide the liquid flow entering the lower vaporization cavity 8 from the second liquid inlet assembly 26, thereby avoiding the problem of splashing of the liquid flow due to the large longitudinal difference between the starting position of the second labyrinth flow channel 22 and the second liquid inlet 4 in the lower vaporization cavity 8.

[0039] As a further preferred embodiment, the first labyrinth flow channel 21 includes two mirror-symmetrical branch flow channels, and the starting position of the first labyrinth flow channel 21 is divided into two parts by a rib plate 28 formed in the upper vaporization cavity 7, and the lower end of the first liquid inlet assembly 25 has two liquid outlet pipes 29 corresponding to the two branch flow channels of the first labyrinth flow channel 21, respectively, so as to divide the liquid flow of the first liquid inlet assembly 25 into the two branch flow channels of the first labyrinth flow channel 21 and vaporize along the extension direction of the first labyrinth flow channel 21, so that the vaporization degree is higher.

[0040] It is worth noting that the labyrinth flow channel is designed in the vaporization cavity, that is, the flow length of the liquid flow from the starting position to the ending position is longer by the design of the ribs and partitions in the vaporization cavity, so that the vaporization time is longer, which is beneficial to improve the vaporization rate, which is a conventional choice in the art. However, in the present embodiment, the liquid flow is divided at the starting position for the upper vaporization cavity, and the tapered column 27 is designed to guide the liquid flow flowing from the relatively high position for the lower vaporization cavity due to the large height difference, which is an improvement of the existing labyrinth flow channel and also has its practical significance.

[0041] As a further preferred embodiment, the first heating passage 10 is arranged around the first labyrinth flow channel 21 in the upper furnace body 5, and the first heating passage 10 contains the first heating body 23, which is used to vaporize the liquid stream flowing into the first labyrinth flow channel 21 through the wall of the first heating passage 10 by conducting the heat of the first heating body 23. Further, the second heating passage 9 is arranged around the second labyrinth flow channel 22 in the lower furnace body 6, and the second heating passage 9 contains the second heating body 24, which is used to vaporize the liquid stream flowing into the second labyrinth flow channel 22 through the wall of the second heating passage 9 by conducting the heat of the second heating body 24. That is, the purpose of independently controlling the vaporization temperature in the two vaporization cavities can be achieved. Specifically, the two heating bodies can be selected as electric heating tubes and electrically connected to an external main control circuit board to achieve the purpose of temperature control. Meanwhile, the shapes of the two heating passages can be U-shaped, S-shaped, or even mosquito-repellent-shaped disc-shaped structures, and are not limited thereto.

[0042] In a preferred embodiment, the first partitioning rib 19 is integrally formed on the upper end surface of the upper furnace body 5, and the first partitioning rib 19 has a plurality of positioning protrusions. The end cover 2 has a plurality of positioning holes 16 corresponding in number and position to the positioning protrusions, so as to facilitate detachable connection of the end cover 2. Further, the second partitioning rib 20 is integrally formed on the upper end surface of the lower furnace body 6, and the lower end surface of the upper furnace body 5 is provided with a clamping groove 17 matching the shape of the second partitioning rib 20, and the upper end of the second partitioning rib 20 is inserted into the clamping groove 17. In this way, the two labyrinth flow channels are not combined by the end surface gap. Meanwhile, both sets of grooves are formed in a downward protruding structure, but can also be in a concave structure, and are not limited thereto.

[0043] As a further preferred embodiment, in the present embodiment, the number of the first steam outlets 14 and the second steam outlets 15 is both two, and they are arranged on the same side wall of the upper furnace body 5. The two first steam outlets 14 and the two second steam outlets 15 are arranged side by side, and the lower end surface of the upper furnace body 5 is recessed upward and provided with a flow guide groove 18 communicating the second steam outlets 15 and the lower vaporization cavity 8. In this way, the steam outlet directions of the two vaporization cavities are consistent, so as to facilitate the arrangement of the steam boiler in the ironing equipment.

[0044] In addition, as shown in FIG. 1, Figure 5 The first labyrinth flow channel 21 is divided into two steam flow channels by the first partitioning rib 19 and corresponds to the two first steam outlets 14, and the second labyrinth flow channel 22 is also divided into two steam flow channels by the second partitioning rib 20 and flows to the two second steam outlets 15 through the flow guide groove 18 at the tail end. The specific directions of the two sets of partitioning ribs are not limited, and the vaporization cavity can be constructed as a labyrinth flow channel. Therefore, the specific directions and arrangements are omitted here, and are not limited to the shapes shown in the figures.

[0045] Referring to Table 1 below, the double-inlet double-cavity independent temperature control type steam boiler provided by the present application, the single electric heating pipe upper and lower double-layer boiler disclosed in patent number CN212714192U, and the conventional single electric heating pipe single-layer boiler are compared. The volumes and test voltage powers of the three boilers are basically the same. The vaporization cavity channel capacity area of the former two is twice that of the latter two due to the double-cavity design. Tests show that the steam quantity (proportional to the vaporization rate) of the double-inlet double-cavity steam boiler provided by the present application is much larger than that of the latter two under the same test voltage power. At the same time, the overall temperature of the former boiler is slightly lower than that of the latter two.

[0046]

[0047] (Table 1)

[0048] In addition, the power of the above-mentioned scheme A (i.e., the double-inlet double-cavity independent temperature control type steam boiler provided by the present application) can be very large to meet the different needs of customers. The maximum voltage power can be 230V; 3000W, and the minimum power can be 120V; 1800W under the premise of meeting the vaporization rate requirement. At the same time, the design of double-cavity double-electric heating pipe makes the overall heat distribution of the boiler uniform, increases the water evaporation contact area, greatly increases the steam quantity per unit time, and thus the vaporization rate is higher. The double-inlet design has double water outlets, so that the water in the boiler is evenly distributed in the boiler, the overall boiler environment temperature is balanced, and the overall boiler temperature is currently tested to be within 210°. The uniform distribution of water quantity can maximize the use of the heat of the boiler, so that the steam quantity is larger under the same conditions.

[0049] As for the above-mentioned scheme B, this product is a handheld steam brush. Due to the influence of appearance, the boiler cannot be made infinitely large, i.e., the electric heating pipe cannot be made large, and the power will be affected. Generally, the maximum can only be 230V; 1600W, and the minimum power that meets the vaporization requirement is 120V; 1400W. Due to the limited volume of the electric heating pipe, the boiler cannot be provided with more energy, so the steam cannot be made large. Moreover, this product has a single water outlet, the boiler channel is long, the water outlet temperature is very low, and the surrounding temperature is high, which can reach 235°.

[0050] Finally, as for the above-mentioned scheme C, this product is a handheld steam brush. Due to the influence of appearance, the boiler cannot be made infinitely large, i.e., the electric heating pipe cannot be made large, and the power will be affected. Generally, the maximum can only be 230V; 1600W. The minimum power that meets the vaporization requirement is 120V; 1400W. Due to the influence of the inability to make the overall product power large, the boiler cannot be provided with sufficient energy, so the steam cannot be made large.

[0051] In summary, compared with the existing double-cavity single-electric heating tube scheme and single-cavity single-electric heating tube scheme, the application can adopt a higher voltage power, and under the condition of the same voltage power, the steam quantity is larger, based on the basic logic that the larger the power is, the higher the vaporization rate is, so the application can obtain a higher vaporization rate.

[0052] It is worth pointing out that the up-and-down arranged double-cavity design provided by the application can also be arranged as left-and-right or front-and-back parallel double-cavity design, which can be realized only by adjusting the positions of the components, and can also be considered as a design of three or more layers, which can be realized only by designing additional water inlet assemblies, water inlets, water channels and steam outlets, and can also achieve the technical purpose of improving the vaporization rate.

[0053] The above only describes the preferred embodiments of the application, which are only illustrative but not limiting. It is understood by those skilled in the art that many changes, modifications and even equivalents can be made to the application within the spirit and scope defined by the claims of the application, and all of them will fall within the protection scope of the application.
