Description

Technical Field

[0001] The invention relates to the technical field of display cabinets, and in particular to an alarm device for a cigarette display cabinet. Background Art

[0002] The background technology of temperature and humidity alarm devices for cigarette display cabinets mainly stems from the strict requirements for the storage environment of cigarettes. As a special commodity, the quality and taste of cigarettes are greatly affected by the storage environment. Changes in temperature and humidity may have adverse effects on the quality of cigarettes, such as causing cigarettes to mold, deteriorate or lose their original flavor. Traditionally, the temperature and humidity control of cigarette display cabinets mainly relies on manual monitoring and manual adjustment, which is not only inefficient, but also difficult to ensure accurate control of temperature and humidity. With the rapid development of electronic information technology and sensor technology, intelligent temperature and humidity monitoring and alarm devices have gradually become standard for cigarette display cabinets. The current cigarette display cabinet alarm system mainly relies on temperature and humidity sensors to monitor the environment inside the cabinet and trigger an alarm when the detected temperature and humidity exceed the preset threshold. However, given that the storage environment of cigarettes is more sensitive, the interior of the display cabinet is usually designed as a highly enclosed space. The staff only opens the cabinet door to take out specific cigarettes when necessary, resulting in poor air circulation in the cabinet space. Therefore, the data measured by the temperature and humidity sensor can often only reflect the local environmental conditions, which to a certain extent affects the reliability of the sensor's detection accuracy; in addition, the inner cavity of the display cabinet is a relatively closed space, and the heat emitted by the lamps inside cannot be discharged in time when in use, causing the temperature in the inner cavity of the display cabinet to continue to rise. Excessive temperature will affect the taste of cigarettes. Summary of the invention

[0029] Furthermore, a ring display lamp 4 is fixedly installed on the top of the inner cavity of the transparent glass cabinet 2. After long-term use, the temperature of the inner cavity of the transparent glass cabinet 2 continues to rise. A temperature sensor 25 and a humidity sensor 26 are fixedly installed on the inner cavity ring wall of the transparent glass cabinet 2. A controller 27 is fixedly installed on the bottom of the inner cavity of the base 1, and the controller 27 is electrically connected to the temperature sensor 25, the humidity sensor 26, the motor 19 and the electric push rod 8. The top of the transparent glass cabinet 2 is connected to two symmetrical air inlet pipes 23. One-way ventilation components 24 are installed on the inner walls of the two air inlet pipes 23. A plurality of air outlet holes are opened on the outer ring wall of the air inlet pipe 10 at equal intervals. 12, an air inlet 6 is provided on the top of the cone display stand 5, a plurality of air outlet holes 14 are provided on the outer ring wall of the movable shell 9 at equal intervals, an annular shell 15 is welded on the inner ring wall of the base 1, a plurality of air outlet holes 16 are provided on the ring wall of the side of the annular shell 15 close to the movable shell 9 at equal intervals, a plurality of air outlet holes 17 are provided on the ring wall of the side of the annular shell 15 away from the movable shell 9 at equal intervals, and a plurality of air outlet holes 18 are provided on the outer ring wall of the base 1 at equal intervals. When the temperature sensor 25 detects that the temperature in the inner cavity of the transparent glass cabinet 2 is higher than the set value, the set temperature sensor 25 sends a signal to the controller 27. The alarm signal is sent, and then the controller 27 controls the motor 19 to stop operating. Then the controller 27 controls the electric push rod 8 to operate. The set electric push rod 8 drives the movable shell 9 to move downward, so that the air outlet hole 2 14 on the outer ring wall of the movable shell 9 is aligned with the air outlet hole 3 16, the air outlet hole 4 17 and the air outlet hole 5 18; at the same time, the set movable shell 9 drives the air inlet pipe, the transmission rod 35, the gear 3 22 and the gear 4 23 to move downward. As the gear 3 22 and the gear 4 23 move downward, the set gear 3 22 and the gear 1 20 are gradually misaligned, and the set gear 4 23 and the gear 2 21 are gradually meshed. After the gear 4 23 and the gear 2 21 are fully meshed, The set motor 19 drives gear one 20 and gear two 21 to rotate again. Since the size of gear two 21 is larger than that of gear four 23, gear two 21 drives gear four 23 to rotate at high speed. The set gear four 23 drives the transmission rod 35, the air inlet pipe one 10 and the fan blades 13 to rotate. The high-speed rotating fan blades 13 fan the gas in the inner cavity of the movable shell 9 to quickly pass through the air outlet two 14, the air outlet three 16, the air outlet four 17 and the air outlet five 18 to be discharged from the inner cavity of the device body, and the external low-temperature gas enters the inner cavity of the device body through the air inlet pipe two 3, so as to cool the inner cavity of the device body.

[0030] Furthermore, two sleeves 31 are fixedly installed in the inner cavity of the base 1, and drying holes 32 are opened on both sides of the two sleeves 31. A drying box 33 is fixedly installed on the top of the movable shell 9, and the two drying boxes 33 are respectively slidably arranged in the inner cavity of the corresponding sleeves 31, and drying holes 34 are opened on both sides of the two drying boxes 33. When the humidity sensor 26 detects that the humidity in the inner cavity of the transparent glass cabinet 2 is higher than the set value, the humidity sensor 26 sends an alarm signal to the controller 27, and then the controller 27 controls the electric push rod 8 to drive the movable shell 9 moves upward. It should be noted that the upward movement distance of the movable shell 9 is less than the thickness of the gear 1 20 and the gear 3 22. The movable shell 9 drives the drying box 33 to move upward, so that the drying hole 1 34 on the side wall of the drying box 33 and the drying hole 2 32 on the side wall of the sleeve 31 are aligned. At this time, the desiccant in the inner cavity of the drying box 33 is exposed to the inner cavity of the transparent glass cabinet 2. When the motor 19 drives the fan blades 13 to perform an internal circulation operation, the desiccant can absorb the water vapor in the inner cavity of the transparent glass cabinet 2, thereby drying the inner cavity of the transparent glass cabinet 2.

[0031] Furthermore, a plurality of springs 28 are connected to the top of the movable shell 9, and the plurality of springs 28 are arranged in a circle with equal intervals, an annular sealing plate 29 is fixedly welded between the tops of the plurality of springs 28, and the annular sealing plate 29 abuts against the bottom of the conical display stand 5, which enhances the airtightness of the connection between the air inlet hole 6 and the air inlet pipe 10 during the internal circulation process; an annular sealing extension plate 30 is welded to the bottom of the movable shell, and the annular sealing extension plate 30 enhances the airtightness between the movable shell 9 and the replacement shell during the internal circulation process.

[0032] Working principle: During daily use, the motor 19 drives the gear 1 20 to rotate, and the gear 1 20 drives the gear 3 22 to rotate. Since the size of the gear 1 20 is smaller than that of the gear 3 22, the gear 1 20 drives the gear 3 22 to rotate at a low speed, and the gear 3 22 drives the transmission rod 35, the air intake pipe 1 10 and the engaging tooth block 2 11 to rotate. Since a plurality of engaging tooth blocks 2 11 and a plurality of engaging tooth blocks 1 7 are alternately arranged in a ring shape, when the engaging tooth block 2 11 rotates, it drives the engaging tooth block 1 7 and the conical display stand 5 to rotate, which facilitates the display of cigarettes placed on the conical display stand 5. At the same time, the air intake pipe 10 drives the fan blade 13 to rotate, and the engaging tooth block 11 drives the fan blade 13 to rotate. The fan blades 13 stir the gas in the inner cavity of the movable shell 9 to be discharged from the inner cavity of the movable shell 9 through the second air outlet hole 14. At the same time, the gas in the inner cavity of the transparent glass cabinet 2 enters the inner cavity of the movable shell 9 through the air inlet hole 6, the air inlet pipe 10 and the air outlet hole 12 in sequence, thereby driving the gas in the inner cavity of the transparent glass cabinet 2 to perform internal circulation operation, thereby improving the detection accuracy of the temperature sensor 25 and the humidity sensor 26; wherein, the annular sealing plate 29 is provided under the elastic force of the spring 28 to abut against the bottom of the conical display stand 5, which enhances the airtightness of the connection between the air inlet hole 6 and the air inlet pipe 10 during the internal circulation process; the annular sealing extension plate 30 is provided to enhance the airtightness between the movable shell 9 and the replacement shell during the internal circulation process;

[0033] After long-term use, the temperature of the inner cavity of the transparent glass cabinet 2 continues to rise. When the temperature sensor 25 detects that the temperature in the inner cavity of the transparent glass cabinet 2 is higher than the set value, the set temperature sensor 25 sends an alarm signal to the controller 27, and then the controller 27 controls the motor 19 to stop working. Then the controller 27 controls the electric push rod 8 to operate, and the set electric push rod 8 drives the movable shell 9 to move downward, so that the second air outlet 14 on the outer ring wall of the movable shell 9 is aligned with the third air outlet 16, the fourth air outlet 17 and the fifth air outlet 18; at the same time, the set The movable housing 9 drives the air intake pipe, the transmission rod 35, the gear 3 22 and the gear 4 23 to move downward. Since the gear 1 20 and the gear 4 23 are gears of the same size, and the gear 2 21 and the gear 3 22 are gears of the same size, as the gear 3 22 and the gear 4 23 move downward, the gear 3 22 and the gear 1 20 are gradually misaligned, and the gear 4 23 and the gear 2 21 are gradually meshed. After the gear 4 23 and the gear 2 21 are fully meshed, the motor 19 drives the gear 1 20 and the gear 2 21 to rotate again. Since the size of the gear 2 21 is The size of the gear 21 is larger than that of the gear 4 23, so that the gear 21 drives the gear 4 23 to rotate at a high speed, and the gear 4 23 drives the transmission rod 35, the air inlet pipe 10 and the fan blade 13 to rotate, and the high-speed rotating fan blade 13 stirs the gas in the inner cavity of the movable shell 9 to quickly pass through the air outlet 2 14, the air outlet 3 16, the air outlet 4 17 and the air outlet 5 18 to discharge the gas from the inner cavity of the device body, and the external low-temperature gas enters the inner cavity of the device body through the air inlet pipe 2 3, so as to cool the inner cavity of the device body; wherein, the setting A one-way ventilation component 24 and a dust filter are provided in the inner cavity of the air inlet pipe 23, so that the external air can only enter the inner cavity of the transparent glass cabinet 2 through the air inlet pipe 23, and the dust filter can block the dust in the air; it should be noted that the movable shell 9 moving downward will drive the engaging gear 21 to move downward, and the engaging gear block 21 after moving downward will no longer engage with the engaging gear 1 20, and the motor 19 will not drive the cone display stand 5 to rotate at a high speed when driving the fan blade 13 to rotate at a high speed, which avoids the situation where the cigarettes placed on the cone display stand 5 are thrown out;

[0034] When encountering rainy weather, the humidity in the outside air is too high. When the staff opens and closes the cabinet door at the front end of the transparent glass cabinet 2 to take out cigarettes, external moisture may enter the inner cavity of the transparent glass cabinet 2; when the humidity sensor 26 detects that the humidity in the inner cavity of the transparent glass cabinet 2 is higher than the set value, the humidity sensor 26 sends an alarm signal to the controller 27, and then the controller 27 controls the electric push rod 8 to drive the movable shell 9 to move up. It should be noted that the upward movement distance of the movable shell 9 is less than the thickness of the gear 1 20 and the gear 3 22. The movable shell 9 is set The shell 9 drives the drying box 33 to move upward, so that the drying hole 1 34 on the side wall of the drying box 33 is aligned with the drying hole 2 32 on the side wall of the sleeve 31. At this time, the desiccant in the inner cavity of the drying box 33 is exposed to the inner cavity of the transparent glass cabinet 2. When the motor 19 drives the fan blades 13 to perform an internal circulation operation, the set desiccant can absorb the water vapor in the inner cavity of the transparent glass cabinet 2, and then dry the inner cavity of the transparent glass cabinet 2; it should be noted that the movable shell 9 after moving upward is still kept in a closed state with the annular shell 15 under the action of the annular sealing extension plate 30.

[0035] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
