[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] The following is for reference. Figures 1 to 3 The steam generating apparatus of this application will be described in detail.

[0033] refer to Figures 1 to 3 According to an embodiment of the present invention, a steam generating device includes a steam generating chamber 100, a first heating rod 200, and a second heating rod 300. The steam generating chamber 100 has a boiling chamber 101 and an explosion chamber 102 that are connected to each other. The explosion chamber 102 is located above the boiling chamber 101. The first heating rod 200 is disposed in the boiling chamber 101 and is used to heat the water in the boiling chamber 101 to generate steam. The second heating rod 300 is disposed in the explosion chamber 102 and is used to heat the steam in the explosion chamber 102.

[0034] For example, such as Figure 3 As shown, the steam generating device includes a steam generating chamber 100, a first heating rod 200, and a second heating rod 300. A boiling chamber 101 and an explosion chamber 102 are formed inside the steam generating chamber 100. The boiling chamber 101 is located below the explosion chamber 102, and the upper end of the boiling chamber 101 is connected to the explosion chamber 102. The first heating rod 200 is disposed in the boiling chamber 101 and extends in the left-right direction. The second heating rod 300 is disposed in the explosion chamber 102 and extends in the left-right direction.

[0035] Furthermore, when the steam generating device of this utility model is in operation, water is placed in the boiling chamber 101 and the water touches the first heating rod 200. The first heating rod 200 heats the water in the boiling chamber 101 to boiling to generate steam. The generated steam enters the explosion chamber 102 upward. After the steam touches the second heating rod 300 in the explosion chamber 102, since the temperature of the second heating rod 300 is much higher than the temperature of the steam itself, the steam undergoes violent vaporization on the surface of the second heating rod 300 to achieve secondary vaporization heating of the steam, thereby further increasing the temperature of the steam.

[0036] It is understood that in the steam generating device of this utility model, by setting a boiling chamber 101 and an explosion chamber 102 connected in the steam generating box 100, and setting a first heating rod 200 in the boiling chamber 101 and a second heating rod 300 in the explosion chamber 102, the steam generated by the first heating rod 200 heating the water in the boiling chamber 101 can be further vaporized under the action of the second heating rod 300 after entering the explosion chamber 102, so as to increase the temperature of the steam output by the steam generating device of this utility model.

[0037] It is understandable that, since the second heating rod 300 is directly installed inside the explosion chamber 102, the steam entering the explosion chamber 102 can directly contact the surface of the second heating rod 300. Through the large temperature difference between the second heating rod 300 and the steam, the steam is further vaporized, thereby enabling the steam temperature to rise rapidly in a short time and improving the efficiency of steam heating.

[0038] It is understood that in the steam generating device of this utility model, higher temperature steam can be generated by only the steam generating box 100, the first heating rod 200 provided in the boiling chamber 101 of the steam generating box 100, and the second heating rod 300 provided in the explosion chamber 102 of the steam generating box 100. The overall structure of the steam generating device of this utility model is simple and the manufacturing cost is low.

[0039] In some embodiments of this utility model, reference is made to Figure 3 The steam generator 100 also has a curved and extended guide channel 103, the two ends of which are connected to the boiling chamber 101 and the explosion chamber 102 respectively.

[0040] It should be noted that when the steam generator is working, the first heating rod 200 heats the water in the boiling chamber 101 to boiling. Correspondingly, during the boiling process in the boiling chamber 101, if the boiling chamber 101 is directly connected to the explosion chamber 102, the boiling water in the boiling chamber 101 is prone to splash into the explosion chamber 102. When this water comes into contact with the second heating rod 300, it will cool down the second heating rod 300, thereby affecting the further vaporization of steam in the explosion chamber 102, and thus causing the temperature of the steam output by the steam generator to be below standard.

[0041] It is understood that in the steam generating device of this embodiment, the boiling chamber 101 is located below the explosion chamber 102, and the boiling chamber 101 and the explosion chamber 102 are connected by a curved and extended guide channel 103. Thus, the steam generated in the boiling chamber 101 can smoothly enter the explosion chamber 102 along the guide channel 103, while the water splashed out in the boiling chamber 101 due to boiling will be blocked by the channel wall of the guide channel 103 and flow back into the boiling chamber 101 under the action of gravity.

[0042] In a further embodiment of the present invention, the guide channel 103 includes a first vertical section 103a, a horizontal section 103b, and a second vertical section 103c connected in sequence. The lower end of the first vertical section 103a is connected to the boiling chamber 101, and the upper end of the second vertical section 103c is connected to the explosion chamber 102.

[0043] For example, such as Figure 3 As shown, the guide channel 103 includes a first vertical section 103a, a horizontal section 103b, and a second vertical section 103c connected in sequence. The horizontal section 103b extends in the front-back direction. The lower end of the first vertical section 103a is connected to the upper end of the boiling chamber 101, the upper end of the first vertical section 103a is connected to the front end of the horizontal section 103b, the lower end of the second vertical section 103c is connected to the rear end of the horizontal section 103b, and the upper end of the second vertical section 103c is connected to the rear end of the explosion chamber 102.

[0044] It is understandable that the water splashed out by boiling in the boiling chamber 101 will be blocked by the channel walls of the first vertical section 103a and the horizontal section 103b, and then flow back into the boiling chamber 101 under the action of gravity.

[0045] In some embodiments of this utility model, the steam generator 100 is provided with a main cavity. The main cavity has a first blocking structure 121 and a second blocking structure 170 respectively on two horizontally opposite cavity walls. The second blocking structure 170 is located above the first blocking structure 121. The portion of the main cavity located below the first blocking structure 121 constitutes a boiling cavity 101. The portion of the main cavity located above the second blocking structure 170 constitutes an explosion cavity 102. The portion of the main cavity located on the horizontal side of the first blocking structure 121 constitutes a first vertical section 103a. The portion of the main cavity located between the first blocking structure 121 and the second blocking structure 170 constitutes a horizontal section 103b. The portion of the main cavity located on the horizontal side of the second blocking structure 170 constitutes a second vertical section 103c.

[0046] For example, such as Figures 1 to 3As shown, the steam generator 100 includes a front wall 110, a rear wall 120, a left wall 130, a right wall 140, an upper wall 150, and a lower wall 160. The front wall 110, rear wall 120, left wall 130, right wall 140, upper wall 150, and lower wall 160 together define a total cavity. The middle part of the rear wall 120 protrudes forward to form a first blocking structure 121. The second blocking structure 170 includes a first blocking plate 171, a second blocking plate 172, and a third blocking plate 173. The first blocking plate 171 and the third blocking plate 173 extend vertically, while the second blocking plate 172 extends horizontally. The lower end of the first blocking plate 171 is connected to the middle part of the front wall 110, and the upper end of the first blocking plate 171 is connected to the middle part of the front wall 110. The front end of the second baffle plate 172 is connected, the lower end of the third baffle plate 173 is connected to the rear end of the second baffle plate 172, the upper end of the third baffle plate 173 and the upper box wall 150 form a steam inlet 102a of the explosion cavity 102, the first baffle structure 121 and the lower box wall 160 form a boiling cavity 101, the first baffle structure 121 and the front box wall 110 form a first vertical section 103a of the guide channel 103, the second baffle plate 172 and the first baffle structure 121 form a horizontal section 103b of the guide channel 103, the third baffle plate 173 and the rear box wall 120 form a second vertical section 103c of the guide channel 103, and the second baffle structure 170, the upper box wall 150 and the front box wall 110 together define the explosion cavity 102.

[0047] It is understood that the front wall 110, rear wall 120, left wall 130, right wall 140, upper wall 150 and lower wall 160 of the steam generator 100 of this utility model are all made of plate. The overall structure of the steam generator 100 of this utility model is simple and the manufacturing cost is low.

[0048] In some embodiments of this utility model, the cavity wall of the explosion chamber 102 is provided with a steam inlet 102a and a steam outlet 102b. The steam inlet 102a is connected to the boiling chamber 101. A barrier 111a is provided between the steam inlet 102a and the steam outlet 102b. The second heating rod 300 is provided between the steam inlet 102a and the barrier 111a.

[0049] For example, such as Figure 3 As shown, the front wall of the explosion chamber 102 is provided with a steam outlet 102b, the rear wall of the explosion chamber 102 is provided with a steam inlet 102a, the baffle 111a extends downward and rearward and is located between the steam outlet 102b and the steam inlet 102a, and the second heating rod 300 is located between the baffle 111a and the steam inlet 102a and is located directly above the second baffle plate 172.

[0050] Subsequently, steam enters the explosion chamber 102 through the steam inlet 102a, is heated by the second heating rod 300, and is then guided to the second baffle plate 172 and the third baffle plate 173 by the blocking action of the baffle member 111a, and is then guided to the steam inlet 102a by the blocking action of the second baffle plate 172 and the third baffle plate 173.

[0051] Understandably, the arrangement of the barrier 111a allows the steam to form an airflow around the second heating rod 300 within the explosion chamber 102, thereby allowing the steam to remain in the explosion chamber 102 for a longer period of time. This enables the second heating rod 300 to fully contact the steam and heat it, resulting in the steam exiting from the steam outlet 102b having a higher temperature.

[0052] In some embodiments of this utility model, the bottom of the explosion cavity 102 is provided with a water collection tank 102c, which is located directly below the barrier 111a.

[0053] For example, such as Figure 3 As shown, the front box wall 110 includes a first front plate 111 and a second front plate 112. The upper ends of the first front plate 111 and the second front plate 112 are connected. The second blocking structure 170 is connected to the upper end of the second front plate 112. The first front plate 111, the second blocking structure 170 and the upper box wall 150 together define the explosion cavity 102. The first blocking plate 171 of the first front plate 111 and the second blocking structure 170 together define a water collection tank 102c, and the water collection tank 102c is located directly below the barrier 111a.

[0054] It is understandable that during the circulation of steam in the explosion chamber 102, some of the steam will liquefy. The water produced by steam liquefaction can be collected in the water collection tank 102c to reduce the impact of the water formed by steam liquefaction on the second heating rod 300.

[0055] In a further embodiment of the present invention, the bottom of the water collection tank 102c is provided with a reflux hole 171a, which is connected to the boiling chamber 101.

[0056] For example, such as Figure 3 As shown, a return hole 171a is provided on the first baffle plate 171 of the second baffle structure 170, and the water collection tank 102c is connected to the guide channel 103 through the return hole 171a.

[0057] Furthermore, the water liquefied by the steam in the explosion chamber 102 can be collected in the water collection tank 102c and returned to the boiling chamber 101 through the return hole 171a and the guide channel 103.

[0058] In some embodiments of this utility model, the steam generating device further includes a water storage tank 400 and a preheating pipe 500. The preheating pipe 500 is disposed in close contact with the lower cavity wall of the boiling chamber 101, and the two opposite ends of the preheating pipe 500 are respectively connected to the boiling chamber 101 and the water storage tank 400.

[0059] For example, such as Figures 1 to 3 As shown, the steam generating device also includes a water storage tank 400 and a preheating pipe 500. The water storage tank 400 is located on the front side of the steam generating box 100. The preheating pipe 500 includes a connecting section 510 and a preheating section 520. The preheating section 520 extends in the left-right direction and is located on the lower side of the boiling chamber 101 and is set in close contact with the lower cavity wall of the boiling chamber 101. The connecting section 510 extends in the front-back direction. The left end of the preheating section 520 is connected to the rear end of the connecting section 510, the right end of the preheating section 520 is connected to the boiling chamber 101, and the front end of the connecting section 510 is connected to the water storage tank 400.

[0060] It is understandable that the cold water in the water storage tank 400 can absorb heat from the boiling chamber 101 during the process of flowing from the preheating section 520 to the boiling chamber 101 to achieve the preheating effect. This can avoid the problem of the water in the boiling chamber 101 stopping boiling due to the large temperature difference between the water in the boiling chamber 101 and the water in the preheating section 520.

[0061] In some embodiments of this utility model, the bottom of the boiling chamber 101 is provided with a waste discharge tank 104, the tank wall of the waste discharge tank 104 is provided with a waste discharge port 104a for discharging liquid, and the preheating pipe 500 is connected to the waste discharge tank 104.

[0062] For example, such as Figure 2 and Figure 3 As shown, the bottom of the boiling chamber 101 is provided with a waste discharge trough 104, which is located at the right end of the bottom of the boiling chamber 101. The right end of the preheating section 520 of the preheating pipe 500 is connected to the waste discharge trough 104.

[0063] It is understood that after the steam generating device of this utility model has finished working, the remaining water in the boiling chamber 101 can be collected in the waste discharge tank 104 and discharged through the waste discharge port 104a.

[0064] It is understandable that, since the right end of the preheating section 520 is connected to the waste discharge tank 104 and the left end of the preheating section 520 is connected to the connecting section 510, and the waste discharge tank 104 is located at the right end of the bottom of the boiling chamber 101, the length of the preheating section 520 can be set to be longer, so that the water in the preheating section 520 can be fully heated before flowing into the boiling chamber 101.

[0065] In some embodiments of this utility model, the steam generating device includes two first heating rods 200, which are respectively installed on two opposite chamber walls of the boiling chamber 101 in the horizontal direction, and the two first heating rods 200 are distributed in the vertical direction.

[0066] For example, such as Figure 2 and Figure 3 As shown, the steam generating device includes two first heating rods 200, which are distributed vertically at intervals. The first heating rod 200 located on the lower side is installed on the left box wall 130, and the first heating rod 200 located on the upper side is installed on the right box wall 140.

[0067] It is understandable that, since the two first heating rods 200 are distributed vertically and are respectively installed on two opposite chamber walls of the boiling chamber 101 in the horizontal direction, the vertical spacing between the two first heating rods 200 can be set to be smaller, so that the two first heating rods 200 can concentrate heat to heat the water in the boiling chamber 101.

[0068] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
