This trend reflects consumers' pursuit of a high-quality and refined lifestyle, and embodies the industry's continuous innovation in technology, design, and materials. The expansion of the market is reflected in the increase in the number of brands, the enrichment of product variety, and the improvement in quality. In terms of market size, the cigar cabinet market has maintained stable growth. As a high-end tobacco product, cigars are gradually gaining market favor. Data shows that the cigar market has maintained stable growth in recent years, and its market size is expected to continue to expand in the coming years. This trend provides ample room for development in the cigar cabinet market.

At the same time, this condensate cannot be reused, requiring users to add water frequently, which is cumbersome and can easily disrupt the stable temperature and humidity environment inside the cabinet.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-8 This utility model provides a technical solution: a condensate recovery structure for a constant temperature and humidity cigar cabinet, including a cigar cabinet 1, a refrigerator compartment 2 inside the cigar cabinet 1, a cabinet door 4 hinged to the front side of the cigar cabinet 1, a fixing plate 7 fixedly connected to the bottom side inside the refrigerator compartment 2, and limiting plates 8 fixedly connected to the left and right sides above the fixing plate 7, a water tank 9 slidably arranged between the two sets of limiting plates 8, an atomizer 11 installed on the rear side of the top of the water tank 9, a cooling cavity 14 opened on the top rear side of the refrigerator compartment 2, a semiconductor refrigeration module installed on the cooling cavity 14, a return groove 15 arranged at the bottom of the cooling cavity 14, and a condensate return water pipe assembly arranged between the return groove 15 and the water tank 9.

[0020] When the condensate recovery structure of this constant temperature and humidity cigar cabinet is in operation, the cabinet door 4 can rotate around the hinge point on the front side of the cigar cabinet 1, realizing the opening and closing of the refrigerator compartment 2. The fixed plate 7 on the bottom side of the refrigerator compartment 2 and the top limiting plate 8 provide a sliding track for the water tank 9, allowing the water tank 9 to be smoothly pulled out between the two sets of limiting plates 8, which is convenient for users to take out or maintain. The atomizer 11 on the top rear side of the water tank 9 is responsible for converting water into mist to humidify the refrigerator compartment 2. The cooling chamber 14 on the top rear side of the refrigerator compartment 2 is used to collect the condensate generated by the cooling component during operation. The condensate flows towards the water tank 9 along the return groove 15 at the bottom of the cooling chamber 14. Through the conduction of the condensate return pipe component, the condensate is recovered into the water tank 9, realizing the recycling of water resources. The heat dissipation component on the rear side of the inside of the cigar cabinet 1 dissipates the heat generated by the cooling component, ensuring the efficient operation of the refrigeration system and maintaining a constant temperature environment in the refrigerator compartment 2.

[0021] The semiconductor refrigeration module includes a semiconductor refrigeration chip, a heat dissipation assembly disposed at one end of the semiconductor refrigeration chip, and a cooling assembly disposed at the other end of the semiconductor refrigeration chip. The heat dissipation assembly includes heat dissipation aluminum and a cooling fan 18. The heat dissipation aluminum is in contact with the heating end face of the semiconductor refrigeration chip, and the cooling fan 18 is disposed behind the heat dissipation aluminum via a mounting bracket. The cooling assembly includes cooling aluminum 26 and a cooling fan 28. The cooling aluminum 26 is provided with a cooling guide protrusion 21, which is in contact with the cooling end face of the semiconductor refrigeration chip. The cooling fan 28 is fixed to the cooling aluminum 26. The cooling aluminum 26 is installed inside the rear side of the cooling cavity 14. The cooling aluminum 26 has several cooling fins 27, and cooling channels are formed between the cooling fins. A mounting plate 13 is fixedly connected to the rear side of the cold storage chamber 2, and a circuit board 20 is installed on the bottom rear side of the mounting plate 13. The heat-dissipating aluminum array has several heat-dissipating fins. The rear side of the cigar cabinet 1 has an air inlet 19, and the sides of the cigar cabinet 1 have corresponding heat dissipation air outlets 6. The heat dissipation fan 18 is used to draw in external air through the air inlet 19 and exchange heat with the several heat dissipation fins, and then discharge it from the corresponding heat dissipation air outlets 6 on both sides of the cigar cabinet 1 to form a heat exchange air duct.

[0022] When the semiconductor cooling module is working, the semiconductor cooling chip 16 generates cooling energy after being powered on. The cooling energy is conducted to the cooling aluminum 26 on the rear side of the cooling cavity 14 through the cooling guide protrusion 21 that abuts against its cooling surface. The cooling aluminum 26 distributes the cooling energy evenly to the area of ​​the cooling cavity 14. After the cooling fan 28 on the front side of the cooling aluminum 26 is started, it guides the air in the refrigerator room into the cooling cavity 14 and cools it through the cooling aluminum 26 and the cooling fins 27. Then, it is discharged from the first air outlet and the second air outlet and blown into the refrigerator room 2, so as to achieve uniform cooling and humidification of the refrigerator room 2. The circuit board 20 on the bottom rear side of the mounting plate 13 coordinates the control of the semiconductor cooling chip 16 and the cooling fan 28 to maintain a constant low temperature environment in the refrigerator room 2.

[0023] The condensate return pipe assembly includes a leak-proof pipe 29, the upper and lower opening diameters of which are smaller than the inner wall diameter. A drain outlet 23 is provided through the bottom left side of the return channel 15. A drain pipe 24 is fixedly connected to the bottom end of the drain outlet 23. The output end of the drain pipe 24 is fixedly connected to the top end of the leak-proof pipe 29. A fixing plate 32 is fixedly sleeved on the outer surface of the bottom end of the leak-proof pipe 29. A sphere 30 is provided on the bottom side of the inside of the leak-proof pipe 29. The diameter of the sphere 30 is larger than the bottom opening diameter of the leak-proof pipe 29. A spring 31 is provided on the top side of the inside of the leak-proof pipe 29. The two sides of the spring 31 abut against the top side of the inside of the leak-proof pipe 29 and the top side of the sphere 30, respectively. A connecting mechanism is provided on the rear side of the top of the water tank 9.

[0024] The connecting mechanism includes a support frame 34. A mounting groove 33 is provided on the rear side of the top of the water tank 9. The mounting groove 33 is located directly below the fixing plate 32. The support frame 34 is fixedly connected to the top side of the mounting groove 33. The top side of the support frame 34 abuts against the outer surface of the sphere 30. A recycling port 35 is provided through the middle of the mounting groove 33.

[0025] When the condensate return pipe assembly is working, some of the water mist liquefies into condensate as the cooling aluminum 26 cools down. The condensate is continuously collected by the return tank 15. When the water tank 9 slides along the limit plate 8 to the appropriate position, the support frame 34 in the mounting groove 33 on the top rear side abuts against and pushes the ball 30 in the leak-proof pipe 29. The ball 30 overcomes the elastic force of the spring 31 and moves upward, making the upper and lower ports of the leak-proof pipe 29 connected. At this time, the condensate from the drain port 23 on the left side of the bottom of the return tank 15 flows into the leak-proof pipe 29 through the drain pipe 24, and then into the water tank 9 through the recovery port 35 in the middle of the mounting groove 33, realizing the recovery of condensate. When the water tank 9 is pulled out, the support frame 34 and the ball 30 lose contact, and the spring 31 pushes the ball 30 downward. The diameter of the ball 30 is larger than the diameter of the bottom opening of the leak-proof pipe 29, thus tightly blocking the bottom opening of the leak-proof pipe 29 and preventing condensate leakage, realizing the automatic recovery and leak-proof function of condensate.

[0026] The heat generated by the heating end face of the thermoelectric cooler 16 is quickly conducted and diffused through the heat dissipation fins 17 that are in contact with the heating end face. The cooling fan 18 is installed on the rear side of the heat dissipation fins 17. After starting, it draws in the outside cold air through the air inlet 19 on the rear side of the cigar cabinet 1, takes away the heat of the heat dissipation fins 17, and then discharges it from the left and right heat dissipation outlets 6, forming a heat dissipation cycle to ensure that the thermoelectric cooler 16 maintains a high-efficiency operating temperature and ensures the stable operation of the refrigeration system.

[0027] A water inlet 10 is provided on the top front side of the water tank 9 for manual replenishment of humidification water.

[0028] The bottom front side of the water tank 9 is provided with a pull-out groove 25, which provides a point of force for the user to pull out.

[0029] The left and right inner walls of the refrigerator compartment 2 are symmetrically provided with several sliding grooves 12. Several shelves 3 are provided inside the refrigerator compartment 2. The left and right sides of the shelves 3 are slidably connected to the sliding grooves 12. The sliding grooves 12 on the left and right inner walls of the refrigerator compartment 2 provide sliding tracks for the shelves 3. The left and right sides of the shelves 3 are embedded in the sliding grooves 12. Users can store cigars according to their storage needs.

[0030] A temperature and humidity sensor 22 is installed on the top side of the interior of the cooling chamber 14 to monitor the temperature and humidity data in the cold storage compartment 2 in real time, convert it into an electrical signal and transmit it to the control system.

[0031] A handle groove 5 is provided on the left side of the cabinet door 4, providing a position for the user to apply force when opening or closing the cabinet door 4.

[0032] Working principle: When the condensate recovery structure of this constant temperature and humidity cigar cabinet is working, the cabinet door 4 can rotate around the hinge point on the front side of the cigar cabinet 1, realizing the opening and closing of the refrigerator compartment 2. The fixed plate 7 on the bottom side of the refrigerator compartment 2 and the top limiting plate 8 provide a sliding track for the water tank 9, so that the water tank 9 can be smoothly pulled out between the two sets of limiting plates 8, which is convenient for users to take out or maintain. The atomizer 11 on the top rear side of the water tank 9 is responsible for converting water into mist. When the semiconductor refrigeration module is working, the semiconductor refrigeration chip 16 generates cooling energy after being energized. The cooling energy is conducted to the heat sink through the cooling guide protrusion 21 that abuts against its cooling surface. The cooling aluminum 26 inside the rear of the cooling cavity 14 distributes the cooling energy evenly to the area of ​​the cooling cavity 14. After the cooling fan 28 in front of the cooling aluminum 26 is started, it guides the air in the refrigerator room into the cooling cavity 14 and cools it through the cooling aluminum 26 and the cooling fins 27. Then, it is discharged from the first air outlet and the second air outlet and blown into the refrigerator room 2, so as to achieve uniform cooling and humidification of the refrigerator room 2. The circuit board 20 at the bottom of the rear side of the mounting plate 13 controls the semiconductor cooling chip 16 and the cooling fan 28 in a coordinated manner to maintain a constant low temperature environment in the refrigerator room 2. The heat generated by the heating end face of the semiconductor cooling chip 16 is quickly conducted and diffused through the heat dissipation fins 17 that are in contact with the heating end face. The cooling fan 18 is installed on the rear side of the heat dissipation fins 17. After starting, it draws in the outside cold air through the air inlet 19 on the rear side of the cigar cabinet 1, takes away the heat of the heat dissipation fins 17, and then discharges it from the left and right heat dissipation outlets 6, forming a heat dissipation cycle to ensure that the semiconductor cooling chip 16 maintains a high-efficiency operating temperature and ensures the stable operation of the refrigeration system. When the mist cools down the aluminum 26, some of the water mist liquefies into condensate. The condensate is continuously collected by the return groove 15 at the bottom of the cooling chamber 14. When the water tank 9 slides along the limiting plate 8 to the appropriate position, the support frame 34 in the mounting groove 33 on the top rear side abuts against and pushes the ball 30 in the leak-proof pipe 29. The ball 30 overcomes the elastic force of the spring 31 and moves upward, making the upper and lower ports of the leak-proof pipe 29 connected. At this time, the condensate from the drain port 23 on the left side of the bottom of the return groove 15 flows into the leak-proof pipe 29 through the drain pipe 24, and then into the water tank 9 through the recovery port 35 in the middle of the mounting groove 33, realizing the recovery of condensate. When the water tank 9 is pulled out, the support frame 34 and the ball 30 are no longer in contact, and the spring 31 pushes the ball 30 downward. The diameter of the ball 30 is larger than the diameter of the bottom opening of the leak-proof pipe 29, thus tightly blocking the bottom opening of the leak-proof pipe 29 and preventing condensate leakage, realizing the automatic recovery and leak-proof function of condensate.
