Description

Technical Field

[0001] This utility model relates to a boiler heating steam passage structure. Background Technology

[0002] Currently, many steam generator products are available on the market, such as steam styling combs. These require an internal pot to heat the water inside, causing it to vaporize and generate steam to curl and style the hair. However, in existing technologies, the water is placed directly inside the pot, limiting the contact area between the water and the pot, thus limiting the amount of steam produced. Therefore, it is necessary to modify the existing internal structure of the pot to increase the contact area between the water and the pot, thereby achieving better water vaporization.

[0003] This utility model was made based on this situation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a boiler heating steam passage structure knife, which has a simple structure and good liquid vaporization effect.

[0005] This utility model is achieved through the following technical solution: a boiler heating steam passage structure, including a concave boiler liner, a boiler lid sealed to the boiler liner, a sealed cavity formed between the boiler liner and the boiler lid, an inlet for connecting an external liquid inlet pipe on the boiler liner, liquid flowing into the sealed cavity through the inlet of the liquid inlet, a steam outlet for discharging steam generated in the sealed cavity outside the boiler lid on the boiler lid, an outlet on the boiler liner corresponding to the steam outlet of the boiler lid, a tortuous channel connecting the inlet and the outlet, and liquid and steam in the sealed cavity flowing to the outlet through the channel.

[0006] As described above, in a boiler heating steam duct structure, the sealed cavity is provided with several sealing ribs. One end of each sealing rib is connected to the bottom of the boiler liner, and the other end is connected to the boiler lid. The sealing ribs divide the sealed cavity into several sealed chambers. Each sealing rib has a through hole, through which liquid and steam in the sealed chambers flow to adjacent sealed chambers. The inlet and outlet are located in different sealed chambers. Liquid and steam flowing out from the inlet pass through at least M sealed chambers before flowing to the outlet, where M is greater than or equal to 1. The through holes connecting the previous sealed chamber and the through holes connecting the next sealed chamber are staggered. Several through holes connect the M sealed chambers between the inlet and outlet to form a channel.

[0007] As described above, in a boiler heating steam duct structure, six sealing ribs are arranged side-by-side in the sealing cavity along the front-back direction of the boiler shell. Both ends of each of the six sealing ribs are connected to the inner wall of the boiler shell. The six sealing ribs sequentially divide the sealing cavity into a first sealing chamber, a second sealing chamber, a third sealing chamber, a fourth sealing chamber, a fifth sealing chamber, a sixth sealing chamber, and a seventh sealing chamber. An eighth sealing chamber, corresponding to the steam outlet of the boiler lid, is independently located within the fourth sealing chamber. The eighth sealing chamber is not connected to the fourth sealing chamber. The inlet is located within the first sealing chamber, and the outlet is located within the eighth sealing chamber. Liquid and steam flowing from the inlet sequentially pass through the first, second, third, fourth, fifth, and sixth sealing chambers before entering the seventh sealing chamber. An intermediate sealing chamber is provided between the seventh and eighth sealing chambers to guide the liquid and steam from the seventh sealing chamber to the eighth sealing chamber.

[0008] As described above, in a boiler heating steam duct structure, along the left-right direction of the boiler shell, a first sealing rib, a second sealing rib, a third sealing rib, and a fourth sealing rib are arranged side-by-side in the sealing cavity. The first and second sealing ribs are located in the fourth sealing chamber and divide the fourth sealing chamber into a fourth left sealing chamber, an eighth sealing chamber, and a fourth right sealing chamber. One end of the third and fourth sealing ribs is connected to the eighth sealing chamber, and the other end passes through the fifth and sixth sealing chambers in sequence before connecting to the seventh sealing chamber. The left and right opposite third and fourth sealing ribs divide the fifth sealing chamber... The system is divided into a fifth left sealing chamber, a fifth middle sealing chamber, and a fifth right sealing chamber. The sixth sealing chamber is further divided into a sixth left sealing chamber, a sixth middle sealing chamber, and a sixth right sealing chamber. The fifth middle sealing chamber and the sixth middle sealing chamber are interconnected to form an intermediate sealing chamber that connects the seventh sealing chamber and the eighth sealing chamber. Liquid and vapor flowing out from the inlet sequentially flow through the first sealing chamber, the second sealing chamber, the third sealing chamber, the fourth left sealing chamber, the fifth left sealing chamber, and the sixth left sealing chamber, or the fourth right sealing chamber, the fifth right sealing chamber, and the sixth right sealing chamber before entering the seventh sealing chamber. After passing through the intermediate sealing chamber, they enter the eighth sealing chamber and flow to the outlet.

[0009] In the boiler heating steam passage structure described above, both the third and fourth sealing ribs have several protruding ribs that extend outwards, and the protruding ribs on the third sealing rib are offset relative to the protruding ribs on the fourth sealing rib.

[0010] In the boiler heating steam passage structure described above, each of the sealing ribs has several protruding ribs that extend outwards.

[0011] In the boiler heating steam passage structure described above, the bottom of the sealing cavity is provided with several recessed pits.

[0012] The boiler heating steam duct structure described above also includes a heating device for heating the boiler drum, which is located below or to the side of the boiler drum.

[0013] In the boiler heating steam passage structure described above, a sealing gasket is provided between the boiler liner and the boiler cover to seal the entire boiler liner, and an air passage for steam to pass through is provided on the sealing gasket at the corresponding steam port.

[0014] As described above, in a boiler heating steam duct structure, the eighth sealed chamber is provided with a frustum that splits the incoming liquid and steam to the left and right. The boiler cover is fixed to the boiler body by a number of threaded fasteners, and the frustum is provided with threaded holes that mate with the threaded fasteners.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The steam passage structure of this utility model has a tortuous channel between its inlet and outlet, which extends the flow path of liquid and steam in the sealed cavity, increases the contact area of ​​the liquid, and achieves better vaporization.

[0017] 2. By incorporating several sealing ribs within the sealed cavity, dividing it into multiple sealed chambers, liquid and steam within each chamber flow through through-holes to adjacent chambers. The inlet and outlet are located in different chambers, ensuring that liquid and steam exiting the inlet pass through at least one sealed chamber before reaching the outlet. The through-holes connecting the preceding and following chambers are staggered, guaranteeing that liquid and steam within the boiler flow only along the designated paths of the sealed chambers and through-holes. This results in a long flow path and excellent vaporization. The entire steam passage structure is simple, ingeniously designed, and easy to manufacture. Furthermore, the outlet can be positioned within a specific sealed chamber to precisely control the steam ejection direction, depending on the application scenario. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1 to 7 The boiler heating steam duct structure shown includes a concave boiler liner 1, with a boiler cover 2 sealed to the liner 1. A sealed cavity 3 is formed between the boiler liner 1 and the boiler cover 2. The boiler liner 1 has an inlet 4 for connecting to an external liquid inlet pipe. Liquid flows into the sealed cavity 3 through the inlet 5 of the inlet 4. The boiler cover 2 has a steam outlet 7 for discharging steam generated in the sealed cavity 3. The boiler liner 1 has an outlet 6 corresponding to the steam outlet 7 of the boiler cover 2. A tortuous channel 8 connects the inlet 5 and the outlet 6. Liquid and steam in the sealed cavity 3 flow through the channel 8 to the outlet 6, and steam is finally ejected from the steam outlet 7. This steam duct structure, with its tortuous channel between the inlet and outlet, extends the flow path of liquid and steam within the sealed cavity, increases the liquid contact area, and achieves better vaporization.

[0028] 3. For example Figure 3 , 4As shown in Figure 5, the sealing cavity 3 is provided with several sealing ribs 9. One end of each sealing rib 9 is connected to the bottom of the inner pot 1, and the other end is connected to the lid 2. The sealing ribs 9 divide the sealing cavity 3 into several sealing chambers. Each sealing rib 9 has a through hole 10. Liquid and steam in the sealing chambers flow to adjacent sealing chambers through the through holes 10. The inlet 5 and outlet 6 are located in different sealing chambers. Liquid and steam flowing out of the inlet 5 pass through at least M sealing chambers before flowing to the outlet 6, where M is greater than or equal to 1. The through holes 10 connecting the previous sealing chamber and the through holes 10 connecting the next sealing chamber are staggered. Several through holes 10 connect the M sealing chambers between the inlet 5 and the outlet 6 to form a channel 8. By setting the sealing ribs 9 to divide the sealing cavity 3 into several sealing chambers, with the inlet 5 and outlet 6 located in different sealing chambers and the through holes between the sealing chambers staggered, the liquid and steam in the inner pot can only flow along the set sealing chamber and through hole paths, resulting in a long flow path and good vaporization effect. In addition, the outlet can be set in a specific sealed chamber according to the application scenario, thereby accurately setting the steam ejection direction.

[0029] In one embodiment, along the front-to-back direction of the inner pot 1, six sealing ribs 9 are arranged side by side in the sealing cavity 3, such as... Figure 5 and 6 As shown, both ends of the six sealing ribs 9 are connected to the inner wall of the pot liner 1. The six sealing ribs 9 divide the sealing cavity 3 into a first sealing chamber 11, a second sealing chamber 12, a third sealing chamber 13, a fourth sealing chamber 14, a fifth sealing chamber 15, a sixth sealing chamber 16, and a seventh sealing chamber 17 in sequence. An eighth sealing chamber 18 corresponding to the steam port 7 of the pot lid 2 is independently provided in the fourth sealing chamber 14. The eighth sealing chamber 18 and the fourth sealing chamber 14 are not connected. The inlet 5 is located in the first sealing chamber 11, and the outlet 6 is located in the eighth sealing chamber 18. The liquid and steam flowing out from the inlet 5 flow through the first sealing chamber 11, the second sealing chamber 12, the third sealing chamber 13, the fourth sealing chamber 14, the fifth sealing chamber 15, and the sixth sealing chamber 16 in sequence before entering the seventh sealing chamber 17. An intermediate sealing chamber 19 is provided between the seventh sealing chamber 17 and the eighth sealing chamber 18 to guide the liquid and steam in the seventh sealing chamber 17 to the eighth sealing chamber 18. It has a simple structure, ingenious design, and is easy to manufacture.

[0030] Among them, the six sealing ribs 9 arranged side by side in the sealing cavity 3 along the front and back direction of the pot liner 1 can be equidistant or the spacing between the sealing ribs can be different.

[0031] Furthermore, in one embodiment, along the left-right direction of the inner pot 1, a first sealing rib 91, a second sealing rib 92, a third sealing rib 93, and a fourth sealing rib 94 are arranged side by side in the sealing cavity 3. The first sealing rib 91 and the second sealing rib 92 are disposed in the fourth sealing chamber 14 and divide the fourth sealing chamber 14 into a fourth left sealing chamber 141, an eighth sealing chamber 18, and a fourth right sealing chamber 142. One end of the third sealing rib 93 and the fourth sealing rib 94 is connected to the eighth sealing chamber 18, and the other end passes through the fifth sealing chamber 141 in sequence. After sealing chamber 15 and the sixth sealing chamber 16, it connects to the seventh sealing chamber 17. The third sealing rib 93 and the fourth sealing rib 94, which are opposite each other on the left and right, divide the fifth sealing chamber 15 into a fifth left sealing chamber 151, a fifth middle sealing chamber 152, and a fifth right sealing chamber 153, and divide the sixth sealing chamber 16 into a sixth left sealing chamber 161, a sixth middle sealing chamber 162, and a sixth right sealing chamber 163. The fifth middle sealing chamber 152 and the sixth middle sealing chamber 162 are interconnected and form an intermediate sealing chamber 19 connecting the seventh sealing chamber 17 and the eighth sealing chamber 18. (See also...) Figure 5 The liquid and vapor flowing out from inlet 5 sequentially pass through the first sealing chamber 11, the second sealing chamber 12, the third sealing chamber 13, the fourth left sealing chamber 141, the fifth left sealing chamber 151, and the sixth left sealing chamber 161, or the fourth right sealing chamber 142, the fifth right sealing chamber 153, and the sixth right sealing chamber 163, before entering the seventh sealing chamber 17. After passing through the intermediate sealing chamber 19, they enter the eighth sealing chamber 18 and flow towards outlet 6. The liquid and vapor in the sealing chamber can flow to the outlet through multiple paths, resulting in a large contact area for the liquid throughout the sealing chamber and good vaporization.

[0032] Of course, in this utility model, sealing ribs can also be set in other sealed chambers along the left and right directions of the pot liner 1 to further divide the sealed chamber.

[0033] Preferably, both the third sealing rib 93 and the fourth sealing rib 94 have several protruding ribs 100 extending outwards, and the protruding ribs 100 on the third sealing rib 93 are offset from the protruding ribs 100 on the fourth sealing rib 94. The protruding ribs 100 on the third sealing rib 93 and the fourth sealing rib 94, and their offset arrangement, not only increase the contact area of ​​the liquid but also allow the liquid and vapor to flow in a curved manner within the sealed chamber, resulting in good vaporization.

[0034] Furthermore, to ensure that the liquid and vapor flow along the designed path and to increase the contact area of ​​the liquid, each of the sealing ribs 9 has several protruding ribs 100. These ribs can be provided on one side or both sides of the sealing rib. Of course, the ribs on the sealing rib can be of the same length, staggered with different lengths, or have multiple different lengths.

[0035] Furthermore, the bottom of the sealing cavity 3 is provided with several recessed pits 200 to increase the contact area of ​​the liquid.

[0036] like Figure 7 As shown, the boiler heating steam duct structure of this utility model also includes a heating device 400 for heating the boiler tank 1. In one embodiment, the heating device can be an MCH heating element. The heating device can be positioned below the boiler tank 1 or on its side. After the power is turned on, the heating device heats the boiler tank to the set temperature and then stops heating. When liquid such as water enters the boiler tank, the water in the sealed cavity gradually heats and vaporizes as it flows from the inlet through each sealed chamber to the outlet, and finally, steam is ejected from the steam outlet 7.

[0037] The boiler heating duct structure includes a sealing gasket 300 between the boiler tank 1 and the boiler cover 2, which completely seals the boiler tank 1. The sealing gasket 300 has a vent 301 corresponding to the steam port 7, allowing steam to pass through. By using the sealing gasket, steam can only be released from the steam port, facilitating subsequent use with other equipment.

[0038] The eighth sealing chamber 18 can be located in the central area of ​​the inner pot 1. For example... Figure 5 As shown, the eighth sealing chamber 18 is equipped with a frustum 20 that diverts the incoming liquid and steam to the left and right. The liquid and steam flow from the middle sealing chamber 19 into the eighth sealing chamber 18 and can be diverted to the outlets on the left and right around the frustum. The outlets 6 can include both left and right outlets. Correspondingly, the pot lid is also provided with two steam ports 7, through which steam is discharged. As one method of fixing the pot lid to the inner pot 1, the pot lid 2 can be fixed to the inner pot 1 by threaded fasteners or other connecting structures. The frustum 20 is provided with threaded holes that mate with the threaded fasteners. The frustum 20 not only diverts the flow but also allows the pot lid 2 to be fixed from the center.
