[0002] Existing cigar cabinets are used for storing cigars. To preserve the quality of cigars during storage, cigar cabinets require strict control of temperature and humidity, maintaining uniform humidity and temperature throughout the interior. A cigar cabinet includes a cabinet body, interior, air ducts, a refrigeration unit, a humidification unit, and a heating unit. The refrigeration, humidification, and heating units are each placed in independent air ducts or cavities before entering the interior through a fan. This results in uneven humidity and temperature of the air entering the interior, making it very difficult to control humidity and temperature uniformity within the interior. This hinders precise control of humidity and temperature fluctuations within the interior, leading to inconsistent humidity and temperature at the air outlet, further contributing to uneven humidity and temperature within the interior. Summary of the Invention

[0036] The present invention will now be described in detail with reference to specific embodiments.

[0037] Example 1: As Figures 1 to 8 As shown, a cigar humidor includes a housing 1, an inner liner 2, an air duct assembly 01, an evaporator 4, and a PTC heater 02. The air duct assembly includes a front baffle 011, an intermediate air duct body 012, and a rear air duct plate 013, arranged sequentially from front to back. The air duct assembly 01 has a left air duct 05, a right air duct, and a fan mounting cavity. The left and right air ducts are vertically arranged. The fan mounting cavity is located at the lower inner end of the air duct assembly. The lower ends of the left and right air ducts are respectively connected to the fan mounting cavity. The front baffle 011 has multiple left air outlets 0111 communicating with the left air duct, and multiple right air outlets 0112 communicating with the right air duct. The rear air duct plate has an air inlet 0131 communicating with the fan mounting cavity. A centrifugal fan 03 is located near the air inlet in the fan mounting cavity. The lower end of the front baffle of the air duct has a lower extension 0113, which extends from the front baffle and is integrated with it. Multiple return air holes 0401 are provided on the lower extension. The air duct assembly is placed inside the inner liner, located in front of the rear panel of the inner liner. The lower extension, the rear panel of the inner liner, and the corresponding inner wall of the inner liner form a combined air duct 04, which communicates with the air inlet. The evaporator and PTC heater 001 are placed inside the combined air duct 04; the evaporator 4 is connected to the compressor. The evaporator has a conventional evaporator structure; the refrigerant pipes can be made of copper or aluminum, and the fins on the evaporator can be made of aluminum.

[0038] The lower extension, together with the back panel of the inner liner and the corresponding inner wall of the inner liner, forms a combined air duct. The combined air duct houses the cooling source, humidification source, and heating source, making reasonable use of space and resulting in a compact structure.

[0039] A water spray pipe 6 is installed on the top of the evaporator, and the water spray pipe has multiple water outlets. The evaporator water receiving box 5 is located below the evaporator 4 to receive the water falling from the evaporator. The water outlets of the evaporator water receiving box are connected to the water tank 3 through the water receiving pipe 501 (return water pipe). The humidifying water pump is located in the water tank, and the humidifying water pump 33 is connected to the water spray pipe 6 through the water suction pipe 61 (humidifying water pipe).

[0040] Like a conventional inner liner, the inner liner contains a temperature and humidity probe 051, and a circuit board is mounted on the casing. The circuit board is electrically connected to components such as the water pump, temperature and humidity probe, and compressor. A circulating fan 052 is located outside the front baffle of the air duct.

[0041] Working principle: When cooling is needed, the compressor operates, cooling the evaporator. Cold air enters the fan mounting cavity through the air inlet under the action of the centrifugal fan. Then, the centrifugal fan rotates and throws the air out through the left and right air ducts, and then out to the inner chamber. The airflow then enters the combined air duct through the return air hole to start the next cycle. When humidification is needed, humidification is achieved by the humidifying water pump drawing water from the water tank and flowing it into the evaporator through the water spray pipe, forming moisture. This moisture is then thrown out through the sealed left and right air ducts by the centrifugal fan, promoting more even air humidity and temperature distribution within the inner chamber. This, combined with the external circulating fan, circulates within the chamber, achieving more uniform humidity and temperature, and allowing for more precise control of temperature and humidity. Additionally, at low temperatures, to reach the set temperature, a PTC heater can be used for heating. The heated air is then spun outwards by a centrifugal fan and blown through two side ducts. An external circulating fan then recirculates the hot air within the humidor, achieving the optimal temperature and humidity for cigar preservation. This structure, with its sealed left and right ducts, prevents airflow loss and facilitates airflow into the humidor, where it is circulated by the internal fan. This spun-air humidor structure promotes more even temperature and humidity distribution, resulting in more precise control of humidity and temperature within the humidor.

[0042] In addition, when the temperature inside the water tank is low during dehumidification or cooling, and the temperature of the air inside the chamber is also lower than the set value, the PTC heater starts and then the centrifugal fan blows hot air outward to heat the temperature inside the chamber to reach the set value.

[0043] By combining the cooling and humidifying air ducts, and installing an evaporator, water spray pipe, and PTC heater 001 within the combined air duct, the cooling source, humidification source, and heating source are all located in the same air duct. The temperature source and humidification source are located in the same air duct. During operation, the airflow enters the air duct assembly and is swung around by a centrifugal fan. The airflow is then swung out by the centrifugal fan and split through the left and right air ducts. This facilitates more uniform airflow temperature and humidity within the air duct, resulting in higher precision in humidity and temperature control within the inner tank.

[0044] Further improvements include placing the shelves on the shelf support strips 201 on the inner walls of the inner liner, similar to a conventional inner liner. The vertical distance between the bottom of the shelf and the left air outlet is 5 mm to 10 mm, and the vertical distance between the bottom of the shelf and the right air outlet is also 5 mm to 10 mm. This ensures that cigars are not blocked from the air outlets, and the corresponding air outlets effectively control temperature and humidity fluctuations within the chamber. The temperature can be controlled within ±1℃, and the humidity within ±2%.

[0045] Example 2: As Figures 1 to 8 As shown, in this example, the side of the duct intermediate body 012 closest to the duct rear plate has a left air duct 0121, a right air duct 0122, and a fan mounting slot 0123. The left air duct 0121 and right air duct 0122 are positioned left and right, and the fan mounting slot is located at the bottom of the intermediate body. The bottom ends of the left and right air ducts are connected to the fan mounting slot, respectively. The left air duct, right air duct, and fan mounting slot are combined with corresponding parts of the inner wall of the duct rear plate to form the left air duct 05, the right air duct, and the fan mounting cavity, respectively. The duct intermediate body 012 has a left air outlet 0124 that connects the corresponding left air outlet to the left air duct, and a right air outlet 0125 that connects the corresponding right air outlet to the right air duct. The duct front baffle 011, the duct intermediate body, and the duct rear plate are arranged and combined together in sequence, and can be glued together to achieve a sealed connection. It can also be a connection, such as a screw connection, where seals can be used at the joints to achieve a seal. Duct components are easy to manufacture, and individual components are suitable for mass production.

[0046] In this example, the air duct intermediate 012 can be made of foamed material.

[0047] The rest is the same as in Example 1.

[0048] Example 3: The characteristic of this example is that, as Figures 8 to 17 As shown, the electric heating element 301 contacts the water tank to heat it. A water spray pipe 6 is installed on the top of the evaporator, with multiple water outlets. Below the evaporator is an evaporator water collection box 5 to collect the water falling from the evaporator. The evaporator water collection box 5 contains a removable filter cotton water collection box 51. The water outlets of the evaporator water collection box are connected to the water tank 3 via a water collection pipe 501 (return water pipe). The humidifying water pump 33 is located inside the water tank and is connected to the water spray pipe 6 via a water suction pipe 61 (humidifying water pipe). The water falling from the evaporator passes through the filter cotton water collection box 51. A temperature sensor is located inside the water tank, and the circuit board is electrically connected to the temperature sensor and the water pump. During operation, when humidification of the inner tank is required, the humidifying water pump operates. When the temperature inside the water tank is lower than the set value, the circuit board controls the electric heating element to heat the water tank.

[0049] In this example, the water tank includes an inner tank liner 31 and an outer tank liner 32. The inner tank liner is placed inside the outer tank liner, and the electric heating element is located at the bottom of the inner tank liner. The inner tank liner can be made of metal or high-temperature resistant plastic. The water temperature does not need to be heated to a very high level; it only needs to be suitable for the normal storage temperature of cigars.

[0050] In this example, the electric heating element is fixed to the outer bottom of the water tank inner liner by wrapping it with aluminum foil. This can be achieved through clamping, screw fixing, or other methods.

[0051] In this example: the opening of the inner tank of the water tank is covered by the water tank cover 34.

[0052] In this example, the inside of the water tank lid is lined with water tank insulation cotton 35. This helps to keep the water inside the tank warm.

[0053] Working Principle: Especially in winter when the temperature is very low, the water temperature in the tank is very low, and the humidity inside the cabinet is insufficient. When humidification is needed, the humidifying water pump operates. When the temperature inside the tank falls below the set value, the circuit board controls the electric heating element to heat the water. The heating element heats the water in the tank to the appropriate temperature. The heated water is then pumped through the humidifying water pump and sprayed onto the evaporator through the spray pipe, achieving evaporation on the evaporator surface and thus humidification. The water then falls into the evaporator water collection box, where it is filtered by the filter cotton. Finally, it flows back to the tank through the outlet of the evaporator water collection box. This ensures that even in low temperatures during winter, the humidification capacity of the system is enhanced, humidification is achieved quickly, and the humidity inside the cabinet reaches the required level rapidly, improving humidification efficiency and promoting more uniform humidity. This provides a better storage environment for cigars.

[0054] The rest is the same as in Example 1 or Example 2.

[0055] Example 4: Figures 9 to 12 As shown, a special feature of this example is that the filter cotton water collection box includes a box body 511 with an open top surface and block-shaped filter cotton 512. The box body 511 has a handle, and the bottom surface of the box body has multiple water outlet holes for the filter cotton water collection box. The filter cotton is placed inside the box body and covers the water outlet holes of the filter cotton water collection box. In this way, the filter cotton can be easily replaced.

[0056] A surrounding plate 52 extends from the corresponding edge of the top opening of the evaporator water collection box, and the front of the surrounding plate has a notch for inserting the filter cotton water collection box. The filter cotton water collection box is located between the end of the evaporator and the top opening.

[0057] The top opening features steps 521 for supporting the filter cotton water collection box; in this example, there are three steps, located on the left, center, and right. The filter cotton water collection box is placed on the evaporator water collection box. The above structures work together harmoniously, allowing consumers to easily replace the filter cotton and quickly remove the filter cotton water collection box, making it more convenient to use. This reduces the impact of impurities in the water on humidification or the storage environment inside the box, thus improving humidification and enhancing its quality. It also improves the preservation of cigars.

[0058] In this example, the internal space enclosed by panel 52 is larger than the lower end of the evaporator, and part of the lower end of the evaporator extends into the panel. This structure facilitates the placement of the filter cotton water collection box, improves its positioning, and prevents water splashing. The overall structure helps ensure humidification capacity and quality.

[0059] The rest is the same as in Example 3.

[0060] Example 5: Figure 14 As shown, a water pump 7 and a drain pump 71 can be installed on or inside the water tank. Water is added to the tank via independent pipelines, and water is drained via the drain pump when the tank needs to be replaced. The inner liner of the water tank can be equipped with a high-level sensor 8 and a low-level sensor 81, which are electrically connected to the circuit board to monitor the water level in the tank.

[0061] The rest is the same as in Example 3 or Example 4.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
