[0055] Embodiment 1:

[0056] like Figure 1 and Figure 2 As shown, this embodiment provides a condensing device, including a shell 1, a fan 2 and an anti-backflow component 3. The shell 1 is provided with a steam inlet 131 and an air inlet. The steam inlet 131 and the air inlet can be arranged on the same side of the shell 1, or on different sides; they can be arranged at the same height of the shell 1 along the height direction, or at different heights. The fan 2 is arranged at the air inlet, and the fan 2 allows the cold air outside the shell 1 to enter the shell 1 from the air inlet. The anti-backflow component 3 is arranged inside the shell 1, and the anti-backflow component 3 divides the inside of the shell 1 into a steam chamber 101 and a condensation chamber 102. The steam inlet 131 is located on the cavity wall of the steam chamber 101, and the air inlet is located on the cavity wall of the condensation chamber 102. The anti-backflow component 3 includes a limiting opening 321 and a movable plate 31. The limiting opening 321 is used to connect the steam chamber 101 and the condensation chamber 102. The movable plate 31 is rotatably connected to the shell 1. Under the action of gravity, the movable plate 31 opens the limiting opening 321 to connect the steam chamber 101 and the condensation chamber 102, so that the steam in the steam chamber 101 enters the condensation chamber 102 to exchange heat with the cold air to achieve condensation.

[0057] The movable plate 31 includes a steam surface near the steam inlet 131 and a condensation surface near the air inlet, and the steam surface and the condensation surface are arranged opposite to each other. When the air pressure on the condensation surface is greater than the air pressure on the steam surface, the movable plate 31 can rotate in the direction close to the steam chamber 101 until it is covered on the limit opening 321, and the limit opening 321 can limit the movable plate 31 from continuing to rotate in the direction close to the steam chamber 101, thereby preventing the cold air with high pressure from entering the steam chamber 101, causing the steam in the steam chamber 101 to reflux and affect the condensation effect. When the air pressure on the steam surface is greater than the air pressure on the condensation surface, the movable plate 31 can rotate in the direction close to the condensation chamber 102 under the action of steam pressure and gravity to open the limit opening 321, reconnect the steam chamber 101 and the condensation chamber 102, and achieve condensation. The condensation device can prevent steam reflux and improve the condensation effect of steam.

[0058] In one embodiment, a heat dissipation structure is further provided in the condensation chamber 102, specifically, the heat dissipation structure includes a heat dissipation plate 4, and the heat dissipation plate 4 is arranged at intervals at the bottom of the condensation chamber 102. When the steam pressure in the steam chamber 101 is close to the cold air pressure in the condensation chamber 102, the steam can enter the condensation chamber 102 from the gap between the movable plate 31 and the shell 1, and flow through the interval space of the heat dissipation plate 4, and exchange heat with the heat dissipation plate 4 to achieve condensation. In other embodiments, the heat dissipation structure can also be other structures such as heat dissipation holes.

[0059] Specifically, the heat sink 4 is a heat sink aluminum plate.

[0060] In one embodiment, the movable plate 31 is directly connected to the side wall of the shell 1 for rotation. By setting a stopper in the steam chamber 101, the movable plate 31 is in a vertical state under the action of gravity, so that a stopper opening 321 is formed between the steam chamber 101 and the condensation chamber 102. When the movable plate 31 rotates to be perpendicular to the side wall of the shell 1, the stopper opening 321 is covered, and the movable plate 31 abuts against the stopper, thereby limiting the movable plate 31 from continuing to rotate in a direction close to the steam chamber 101. One or more movable plates 31 may be provided. When one movable plate 31 is provided, when one movable plate 31 rotates to be perpendicular to the side wall of the shell 1, the four sides of the movable plate 31 abut against the side wall of the shell 1, so that one stopper opening 321 is covered. When multiple movable plates 31 are provided, the multiple movable plates 31 are arranged in sequence, and when the multiple movable plates 31 are simultaneously rotated to be perpendicular to the side wall of the shell 1, the multiple limit openings 321 are covered, and the multiple movable plates 31 are simultaneously rotated toward the direction close to the condensation chamber 102, and the limit openings 321 are reopened to achieve communication between the steam chamber 101 and the condensation chamber 102.

[0061] In one embodiment, if Figure 3-Figure 8As shown, the backflow prevention assembly 3 also includes a fixed plate 32, which is fixedly arranged inside the shell 1 and divides the inside of the shell 1 into a steam chamber 101 and a condensation chamber 102. The fixed plate 32 is provided with a plurality of limit openings 321, and the movable plate 31 is provided with a plurality of limit openings 321, and the plurality of limit openings 321 and the plurality of movable plates 31 are arranged one-to-one, and the movable plate 31 can open or close the limit openings 321 by rotating. When the movable plate 31 rotates to open the limit opening 321, the steam in the steam chamber 101 enters the condensation chamber 102, and when the movable plate 31 rotates to cover the limit opening 321, the cold air in the condensation chamber 102 cannot enter the steam chamber 101, thereby preventing the steam from flowing back.

[0062] In one embodiment, if Figure 3 and Figure 4 As shown, the movable plate 31 is arranged on a side of the fixed plate 32 close to the condensation chamber 102, one side of the movable plate 31 is rotatably connected to the fixed plate 32, and both ends of the movable plate 31 are provided with protrusions 311, which abut against the fixed plate 32 to limit the movable plate 31 from rotating into the steam chamber 101. The fixed plate 32 is connected to the side wall of the housing 1, and the movable plate 31 is rotatably connected to the fixed plate 32. When the movable plate 31 rotates in a direction close to the steam chamber 101 until it abuts against the fixed plate 32, the movable plate 31 just closes the limiting opening 321 to separate the steam chamber 101 from the condensation chamber 102. When the movable plate 31 continues to rotate in a direction close to the steam chamber 101, the protrusion 311 is blocked by the fixed plate 32, so that the movable plate 31 cannot continue to rotate. Under the action of gravity of the movable plate 31 and the steam pressure, the movable plate 31 rotates toward the condensation chamber 102 to open the limiting opening 321 , and the steam in the steam chamber 101 enters the condensation chamber 102 through the limiting opening 321 .

[0063] In one embodiment, the movable plate 31 is rotatably connected to the fixed plate 32 via the rotating shaft 33, both ends of the position-limiting opening 321 are provided with fixing holes, one side of the movable plate 31 is provided with a first connecting hole, and the rotating shaft 33 passes through the first connecting hole and is connected to the fixing hole, so that the movable plate 31 can rotate relative to the rotating shaft 33. During assembly, the rotating shaft 33 first passes through the first connecting hole, and then the two ends of the rotating shaft 33 are respectively inserted into the two fixing holes to complete the installation of the movable plate 31.

[0064] In one embodiment, the backflow prevention assembly 3 further includes a fixed pressure plate 34, which is arranged on a side of the fixed plate 32 away from the condensation chamber 102, and the fixed pressure plates 34 are arranged at both ends of the limiting opening 321, and the fixed pressure plates 34 are arranged with arc-shaped protrusions 341, and a fixing hole is formed between the arc-shaped protrusions 341 and the fixed plate 32, and the rotating shaft 33 is connected with the fixing hole after passing through the movable plate 31. By setting the fixed pressure plate 34, during assembly, after the rotating shaft 33 passes through the first connecting hole, the two ends of the rotating shaft 33 are respectively placed at the two ends of the limiting opening 321, and then the fixed pressure plate 34 is placed above the rotating shaft 33, the arc-shaped protrusions 341 are aligned with the rotating shaft 33, and then the fixed pressure plate 34 is fixed to the fixed plate 32 by screw connection or clamping. Such a setting is more convenient for assembling the movable plate 31.

[0065] Since the movable plate 31 is located on the side of the fixed plate 32 close to the condensation chamber 102, and the fixing hole is located on the side of the fixed plate 32 close to the steam chamber 101, in order to realize the connection between the movable plate 31 and the rotating shaft 33, in one embodiment, both ends of the movable plate 31 are provided with connecting ears 312, the connecting ears 312 extend in a direction perpendicular to the movable plate 31, and the connecting ears 312 are provided with a first connecting hole, and both ends of the side of the limiting opening 321 close to the rotating shaft 33 are provided with limiting grooves 322, and after the connecting ears 312 pass through the limiting grooves 322, the two ends of the rotating shaft 33 pass through the two first connecting holes respectively. The connecting ears 312 pass through the limiting grooves 322 and extend out of the side of the fixed plate 32 close to the steam chamber 101, so that the rotating shaft 33 can be connected to the fixing hole after passing through the first connecting hole.

[0066] Furthermore, if Figure 5-Figure 9 As shown, when the movable plate 31 rotates to open the limit opening 321, the outer wall of the connecting ear 312 abuts against the inner wall of the limit groove 322, so that the angle between the movable plate 31 and the fixed plate 32 is an acute angle. The limit groove 322 cooperates with the connecting ear 312 to limit the angle between the movable plate 31 and the fixed plate 32 when the limit opening 321 is opened, so as to avoid the angle between the movable plate 31 and the fixed plate 32 being too large. When the air pressure on the condensation surface is greater than the air pressure on the steam surface, the movable plate 31 cannot be driven to rotate, causing the limit opening 321 to be always in an open state, and the steam backflow cannot be prevented.

[0067] In one embodiment, the fixing plate 32 includes a first fixing plate 3201, which is arranged between the steam inlet 131 and the air inlet and perpendicular to the side wall of the shell 1 to separate the interior of the shell 1 into a steam chamber 101 and a condensation chamber 102 along the height direction.

[0068] The housing 1 includes a top wall, a first side wall 11, a second side wall 12, a third side wall 13 and a fourth side wall. The first side wall 11, the second side wall 12, the third side wall 13 and the fourth side wall are arranged around the top wall. The first side wall 11 and the second side wall 12 are arranged opposite to each other, and the third side wall 13 and the fourth side wall are arranged opposite to each other. The bottom of the housing 1 is through-set for connecting with the housing 1. Fig.11 The condensation channel 5 shown is connected, and the heat dissipation plate 4 is arranged at the bottom of the shell 1 and extends into the condensation channel 5.

[0069] In this embodiment, the steam chamber 101 is located above the top wall, and the condensation chamber 102 is located below the top wall. In other embodiments, the housing 1 may also be configured to include a top wall, a first side wall 11, a second side wall 12, a third side wall 13, and a bottom wall, and the first fixing plate 3201 is perpendicular to the top wall, the bottom wall, and the third side wall 13 to separate the interior of the housing 1 into the steam chamber 101 and the condensation chamber 102 along the width direction.

[0070] Further, continue to refer to Figure 8 The fixed plate 32 also includes a second fixed plate 3202, which is tilted inside the housing 1; one end of the first fixed plate 3201 is connected to the first side wall 11, and the other end is connected to one end of the second fixed plate 3202, and the other end of the second fixed plate 3202 is tilted to extend to the second side wall 12. When the movable plate 31 rotates to open the limit opening 321, the angle between the movable plate 31 on the first fixed plate 3201 and the first fixed plate 3201 is a first angle α 1 The angle between the movable plate 31 on the second fixed plate 3202 and the second fixed plate 3202 is the second angle α 2 , the first angle α 1 and the second angle α 2 The angles are different.

[0071] In this embodiment, the steam inlet 131 and the air inlet are respectively arranged on different side walls of the housing 1. The air inlet is arranged on the first side wall 11, and the steam inlet 131 is arranged on the third side wall 13, so that the air inlet is arranged opposite to the second fixing plate 3202, so as to prevent the cold air from flowing to the second side wall 12 after entering from the air inlet, but to meet with the steam entering the condensation chamber 102 through the limiting opening 321 on the second fixing plate 3202, and exchange heat. Such an arrangement has a better condensation effect.

[0072] Since the first fixed plate 3201 is horizontally arranged and located above the air inlet, under the action of gravity, the movable plate 31 opens the limiting opening 321, and is restricted by the cooperation between the limiting groove 322 and the connecting lug 312, the first angle α 1 Less than 90°, avoid the first angle α 1When the angle is equal to or greater than 90°, the wind force of the fan 2 is slightly greater than the steam pressure. Although the air pressure on the condensation surface is greater than the air pressure on the steam surface, the movable plate 31 cannot be driven to rotate to close the limit opening 321, thereby causing the cold air blown into the condensation chamber 102 by the fan 2 to enter the condensation chamber 102 through the limit opening 321, causing steam reflux.

[0073] The movable plate 31 on the second fixed plate 3202 is in a vertical state under the action of gravity, and the second angle α 2 is related to the angle between the second fixing plate 3202 and the horizontal plane, the second angle α 2 It is equal to 90° minus the angle between the second fixed plate 3202 and the horizontal plane. Since the second fixed plate 3202 is arranged directly opposite to the air inlet, under the condition of constant air inlet pressure, the force exerted by the air inlet pressure on the movable plate 31 on the second fixed plate 3202 is greater than the force exerted on the movable plate 31 on the first fixed plate 3201. Therefore, the movable plate 31 in a vertical state on the second fixed plate 3202 can be driven with a smaller air inlet pressure, so that when the wind force of the fan 2 is slightly greater than the pressure of the steam, the movable plate 31 on the second fixed plate 3202 can be driven to rotate and close the limit opening 321.

[0074] In other embodiments, the steam inlet 131 and the air inlet may also be disposed on the same side. Exemplarily, the steam inlet 131 and the air inlet are both disposed on the first side wall 11 , or are both disposed on the third side wall 13 .

[0075] In one embodiment, a plurality of limiting openings 321 are arranged at intervals on the first fixed plate 3201 and the second fixed plate 3202, and a plurality of movable plates 31 are arranged one-to-one corresponding to the plurality of limiting openings 321. A plurality of limiting openings 321 and movable plates 31 are arranged on the first fixed plate 3201 and the second fixed plate 3202, and when the movable plate 31 opens the limiting openings 321, the steam in the steam chamber 101 can evenly enter the condensation chamber 102 through the plurality of limiting openings 321, and evenly mix with the cold air in the condensation chamber 102 to exchange heat, thereby further improving the condensation effect.

[0076] In one embodiment, the backflow prevention component 3 also includes a support frame, which includes a support plate 35, a top plate and three side plates. The first fixed plate 3201 is the top plate of the support frame, and the second fixed plate 3202 is one of the side plates of the support frame. The support plate 35 extends upward from one end of the first fixed plate 3201 away from the second fixed plate 3202. A second connecting hole 351 is provided on the support plate 35. The support plate 35 is fitted with the first side wall 11, and the screw passes through the second connecting hole 351 and is screwed and fixed to the first side wall 11; the remaining two side plates are respectively arranged on both sides of the second fixed plate 3202, and are respectively fitted and connected with the third side wall 13 and the fourth side wall.
