A greenhouse dehumidification device for winter

Abstract

This invention relates to the field of agricultural technology and discloses a greenhouse winter dehumidification device, including a dehumidification cabinet, a dehumidification mechanism, a self-cleaning mechanism, and an ice removal mechanism. The ice removal mechanism consists of a servo motor, a reciprocating transmission assembly, and an ice removal protrusion. The technical solution of this invention utilizes a servo motor, a reciprocating transmission assembly, and an ice removal protrusion. The reciprocating transmission assembly converts the rotational force of the servo motor into linear reciprocating movement, driving the ice removal protrusion to move rapidly back and forth. During this movement, the protrusion continuously strikes multiple corrugated cooling fins in the evaporator, achieving uniform high-frequency vibration propagation on the corrugated cooling fins. This effectively breaks up the thin ice condensed on the corrugated cooling fins, achieving a continuous and efficient ice removal effect. This effectively prevents thin ice from affecting the normal operation and heat exchange efficiency of the evaporator, ensuring the safety of the evaporator and the stable and continuous heat exchange performance during continuous low-temperature dehumidification.

Description

Technical Field

[0001] This invention relates to the field of agricultural technology, and in particular to a dehumidification device for greenhouses in winter. Background Technology

[0002] Greenhouses are essential facilities for agricultural production, especially in winter. As temperatures drop, water vapor in the air easily condenses into liquid water, forming condensate. This not only increases soil moisture content, affecting crop growth, but can also create a breeding ground for pests and diseases. Therefore, dehumidification is a crucial measure in greenhouses during winter. While traditional natural ventilation methods are simple and inexpensive, their effectiveness is limited in cold winter conditions, especially on days unsuitable for natural ventilation. Therefore, dehumidification devices are needed to reduce the moisture content in the greenhouse air, control humidity, and ensure crops grow in an ideal environment.

[0003] In greenhouses, existing dehumidification devices operate by using evaporators to dehumidify at low temperatures, maintaining the humidity within a suitable range. However, to ensure the evaporator functions properly, it needs to continuously cool down to condense moisture in the air. This causes the cold surface of the evaporator to easily frost or ice up. The formation of ice not only reduces the heat exchange efficiency of the evaporator and affects the dehumidification effect, but also seriously affects the normal operation of the evaporator, causing damage and ultimately affecting the overall performance of the dehumidification device.

[0004] Therefore, the aforementioned technical problems need to be solved. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention proposes a dehumidification device for greenhouses in winter, which solves the problem that a thin layer of ice easily forms on the inner surface of the evaporator due to frequent use of the cooling function. The formation of this ice layer will seriously affect the normal operation and heat exchange efficiency of the evaporator, and thus affect the dehumidification effect.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows: A greenhouse winter dehumidification device includes a dehumidification cabinet, a dehumidification mechanism, a self-cleaning mechanism, and an ice removal mechanism. The dehumidification cabinet has a mounting frame fixedly installed inside. The mounting frame consists of a fan frame, a protective frame, a guide plate, and a fixing frame. The protective frame is fixedly installed at the bottom of the fan frame. The top of the guide plate is bolted to the bottom of the protective frame. The fixing frame is fixedly installed on the top wall of the dehumidification cabinet. The fan frame has a ventilation opening inside, and a fan is fixedly installed on one side of the ventilation opening. The dehumidification mechanism is fixedly installed on the front of the fan frame via a protective frame and a fixing frame. The dehumidification mechanism consists of an inlet condenser, an outlet condenser, an evaporator, a compressor, and two capillary tubes. The inlet condenser and the outlet condenser are located on the front and back of the evaporator, respectively, and are connected to the evaporator through two capillary tubes. The output end of the compressor is connected to the inlet condenser and the outlet condenser through a three-way pipe, and the input end of the compressor is connected to the evaporator through a suction pipe. The self-cleaning mechanism is fixedly installed on the top of the mounting bracket.

The first dust removal component is located outside the air inlet condenser, and the second dust removal component is located outside the air outlet condenser. The inner sides of the first dust removal component and the second dust removal component are in contact with the front and back of the evaporator. The first gear transmission component is fixedly installed at the bottom of one side of the first dust removal component and is meshed with one end of the worm gear transmission component. The second gear transmission component is fixedly installed at the bottom of one side of the second dust removal component and is meshed with one end of the bevel gear transmission component. The de-icing mechanism is fixedly installed at the bottom of the fan frame and extends into the protective frame through a slide groove. The de-icing mechanism consists of a servo motor, a reciprocating transmission assembly, and a de-icing protrusion. One end of the reciprocating transmission assembly is fixedly connected to the output end of the servo motor, the de-icing protrusion is driven by the reciprocating transmission assembly, and the other end of the reciprocating transmission assembly is driven by the other end of the bevel gear transmission assembly and the worm gear transmission assembly, respectively. A servo motor, when powered, drives a reciprocating transmission assembly to move a de-icing protrusion rapidly back and forth. This rapidly moving protrusion strikes the evaporator, breaking up the thin layer of ice that has condensed on it, thus achieving de-icing. Simultaneously, the servo motor transmits power to a bevel gear transmission assembly and a worm gear transmission assembly via the reciprocating transmission assembly. One end of the bevel gear transmission assembly meshes with a second gear transmission assembly, driving a second cleaning assembly. The other end of the worm gear transmission assembly meshes with a first gear transmission assembly, driving a first cleaning assembly. The first and second cleaning assemblies clean the front and back of the inlet condenser, outlet condenser, and evaporator, achieving self-cleaning and ensuring the thermal conductivity of the inlet condenser, outlet condenser, and evaporator.

[0007] Preferably, the reciprocating transmission assembly consists of a synchronous belt pulley, a transmission bevel gear rod, a worm gear, and a half-tooth gear transmission assembly.

The spline drive component in the first dust removal component is meshed with the first gear drive component, and the spline drive component in the second dust removal component is meshed with the second gear drive component. The spline transmission assembly consists of two spline transmission rods and two spline bevel gears. The bottom ends of the two spline transmission rods are fixedly connected to the top of the first gear transmission assembly. The first gear transmission assembly drives the two spline transmission rods to rotate, and the rotating two spline transmission rods drive the two spline bevel gears to rotate respectively. The rotary roller assembly consists of two linked bevel gears and two cleaning rollers. One end of each cleaning roller is fixedly equipped with a linked bevel gear, which meshes with a splined bevel gear. The splined bevel gears are movably connected to each other via a bearing bracket. The two rotating splined bevel gears drive the two linked bevel gears to rotate, which in turn drive the corresponding two cleaning rollers to rotate. The two rotating cleaning rollers then perform the cleaning operation. The lifting assembly consists of two lifting gears, two racks, two guide sleeves, and two guide rods. One end of each of the two lifting gears is fixedly mounted on the other end of each of the two cleaning rollers. One end of each of the two guide sleeves is rotatably mounted on the other end of each of the two lifting gears, and the two guide sleeves are movably sleeved on the outside of each of the two guide rods. The two guide rods are fixedly mounted on the bottom of the fan frame. The two racks are meshed with the two lifting gears, and the two racks are fixedly mounted on the bottom of the fan frame. The rotating cleaning rollers drive the lifting gears to rotate, and the rotating lifting gears drive the cleaning rollers to move up and down through the racks. The guide sleeves move and guide the cleaning rollers on the outside of the guide rods, so that the cleaning rollers move up and down while rotating.

[0010] Preferably, the first gear transmission assembly consists of a first driving gear and two first driven gears. The two first driven gears are symmetrically mounted on both sides of the first driving gear and mesh with both sides of the first driving gear. A first bevel gear is fixedly mounted on the top of the first driving gear.

[0011] Preferably, the second gear transmission assembly consists of a second driving gear and two second driven gears.

[0012] Preferably, the worm gear transmission assembly consists of a first transmission rod, a worm gear, and a third bevel gear.

[0014] Preferably, a top cabinet is fixedly installed on the top of the dehumidifier, a cabinet door is installed on the front of the dehumidifier via a bracket, and a water tank is inserted and installed at the bottom inside the dehumidifier.

[0015] The beneficial effects of this invention are: The technical solution of this invention, by setting up a servo motor, a reciprocating transmission assembly, and a de-icing protrusion, converts the rotational force of the servo motor into linear reciprocating motion through the reciprocating transmission assembly, driving the de-icing protrusion to move rapidly back and forth. Specifically, the rotational force of the servo motor is transmitted to the transmission bevel gear and worm gear through a synchronous belt pulley, synchronously driving two half-toothed gear components to rotate. The reciprocating rack is alternately meshed by the synchronously rotating two half-toothed gear components, inducing linear reciprocating motion, causing the movable rods at both ends of the reciprocating rack to move back and forth along the support sleeve, realizing rapid axial reciprocating motion; this drives the de-icing protrusion, which is fixedly connected to the movable rod, to move rapidly back and forth. This movement process affects the evaporator... Multiple corrugated cooling fins are continuously struck, achieving uniform high-frequency vibration propagation across the fins. This effectively breaks up the thin ice condensed on the fins, achieving continuous and efficient de-icing. This effectively prevents the thin ice condensed on the evaporator from affecting its normal operation and heat exchange efficiency. Throughout the process, no shutdown is required for de-icing, ensuring the safety of the evaporator and stable heat exchange performance during continuous low-temperature dehumidification. This guarantees continuous and efficient operation of the evaporator, improving reliability and efficiency. It also solves the problem of evaporators easily freezing and affecting heat exchange efficiency in continuous low-temperature dehumidification environments. Attached Figure Description

[0018] The following will be combined with the appendix Figure 1 To be continued Figure 12 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] A greenhouse winter dehumidification device includes a dehumidification cabinet 1, a dehumidification mechanism 2, a self-cleaning mechanism 3, and a de-icing mechanism 4. An installation frame 103 is fixedly installed inside the dehumidification cabinet 1. The installation frame 103 is composed of a fan frame 1031, a protective frame 1032, a guide plate 1033, and a fixing frame 1034. The protective frame 1032 is fixedly installed at the bottom of the fan frame 1031. The top of the guide plate 1033 is bolted to the bottom of the protective frame 1032. The fixing frame 1034 is fixedly installed on the top wall of the dehumidification cabinet 1. A ventilation opening is provided inside the fan frame 1031, and a fan 5 is fixedly installed on one side of the ventilation opening. The dehumidification mechanism 2 is fixedly installed on the front of the fan frame 1031 via the protective frame 1032 and the fixing frame 1034. The dehumidification mechanism 2 consists of an inlet condenser 201, an outlet condenser 202, an evaporator 203, a compressor 204, and two capillary tubes 205. The inlet condenser 201 and the outlet condenser 202 are located on the front and back of the evaporator 203, respectively, and the inlet condenser 201 and the outlet condenser 202 are respectively connected to the evaporator 203 through the two capillary tubes 205. The output end of the compressor 204 is connected to the inlet condenser 201 and the outlet condenser 202 through a three-way pipe, and the input end of the compressor 204 is connected to the evaporator 203 through a suction pipe. The evaporator 203 consists of a coil and multiple corrugated cooling fins. The coil passes through multiple corrugated cooling fins. The liquid inlet end of the coil is connected to the output end of the compressor 204. The liquid outlet end of the coil is connected to two capillary tubes 205 through a three-way pipe. The guide plate 1033 is located below the evaporator 203 to facilitate the diversion of liquid dripping from the evaporator 203 and the de-icing process of the evaporator 203 to the water tank 104. When the compressor 204 is powered on, it compresses the refrigerant, turning it into a high-temperature, high-pressure liquid. This liquid is then distributed to the inlet condenser 201 and the outlet condenser 202 through a three-way pipe. This process enables the refrigerant to undergo efficient heat exchange at higher temperatures and pressures, thereby accelerating the efficiency of heat exchange. Heat is dissipated through the inlet condenser 201 and the outlet condenser 202. The inlet condenser 201 and the outlet condenser 202 effectively cool the refrigerant into a low-temperature, high-pressure liquid through heat exchange with the air. Then, the refrigerant is delivered to the evaporator 203 through two corresponding capillary tubes 205. The low-temperature, high-pressure refrigerant is introduced into the evaporator 203 through the capillary tubes 205. The narrow design of the capillary tubes 205 causes the refrigerant to expand into a gas as it passes through, and the temperature drops significantly. This expansion process allows the refrigerant to exchange heat in the evaporator 203, absorbing heat from the coil of the evaporator 203, making the coil cooler and achieving a better cooling effect. The gas that has absorbed heat enters the suction pipe through the coil of the evaporator 203 and flows to the compressor 204. The compressor 204 then compresses the gas again into a high-temperature, high-pressure gas, starting a new refrigeration cycle. When the fan 5 is powered on, it generates suction, drawing the humid air inside the greenhouse into the dehumidifier 1. The incoming air is heated by the air inlet condenser 201, which preheats the cold air inside the greenhouse, preventing the humid cold air from directly entering the evaporator 203. The preheating of the cold air inside the greenhouse by the air inlet condenser 201 ensures that the air is at the most suitable temperature for dehumidification when it enters the evaporator 203, effectively preventing the evaporator 203 from frosting under low temperature conditions. It can also dehumidify evenly in greenhouses with different temperatures, thereby ensuring dehumidification efficiency and effect. By first heating the air and then cooling and dehumidifying it, frost formation on the evaporator 203 can be effectively avoided, improving operating efficiency. This temperature control technology also makes the dehumidification process more stable and adaptable to humidity adjustment needs in different temperature ranges, thereby achieving a more efficient dehumidification effect. The heated air enters the cold evaporator 203, causing the humid air to condense on the corrugated cooling fins. The condensed water collects on the corrugated cooling fins and then drips into the guide plate 1033 below, which guides it to the water tank 104, effectively collecting the water generated during the dehumidification process. The dehumidified air enters the outlet condenser 202, where heat exchange occurs between the dehumidified air and the condenser, ensuring that the discharged dry air does not lower the temperature inside the greenhouse, thus improving comfort and plant growth conditions and better meeting the environmental control requirements of the greenhouse. The self-cleaning mechanism 3 is fixedly installed on the top of the mounting bracket 103. The self-cleaning mechanism 3 consists of a first dust removal component 301, a second dust removal component 302, a first gear transmission component 303, a second gear transmission component 304, a bevel gear transmission component 305, and a worm gear transmission component 306. The first dust removal component 301 is located on the outside of the air inlet condenser 201, and the second dust removal component 302 is located on the outside of the air outlet condenser 202. The inner sides of the first dust removal component 301 and the second dust removal component 302 are in contact with the front and back of the evaporator 203. The first gear transmission component 303 is fixedly installed on the bottom end of one side of the first dust removal component 301. The first gear transmission component 303 is meshed with one end of the worm gear transmission component 306. The second gear transmission component 304 is fixedly installed on the bottom end of one side of the second dust removal component 302. The second gear transmission component 304 is meshed with one end of the bevel gear transmission component 305. The de-icing mechanism 4 is fixedly installed at the bottom of the fan frame 1031 and extends into the protective frame 1032 through a slide groove. The de-icing mechanism 4 consists of a servo motor 401, a reciprocating transmission assembly 402 and a de-icing protrusion 403. One end of the reciprocating transmission assembly 402 is fixedly connected to the output end of the servo motor 401. The de-icing protrusion 403 is connected to the reciprocating transmission assembly 402. The other end of the reciprocating transmission assembly 402 is connected to the other end of the bevel gear transmission assembly 305 and the worm gear transmission assembly 306, respectively. The reciprocating transmission assembly 402 consists of a synchronous pulley 4021, a transmission bevel gear rod 4022, a worm gear 4023, and a half-tooth gear transmission assembly 4024. One end of the transmission bevel gear rod 4022 and one end of the worm gear 4023 are both connected to the synchronous pulley 4021. The other end of the transmission bevel gear rod 4022 is meshed with one end of the bevel gear transmission assembly 305. The worm gear 4023 is meshed with one end of the worm gear transmission assembly 306. The semi-tooth gear transmission assembly 4024 consists of a reciprocating rack 4025, two movable rods 4026, and two semi-tooth gears 4027. The two semi-tooth gears 4027 are symmetrically distributed on both sides of the reciprocating rack 4025 and dynamically mesh with the reciprocating rack 4025. One semi-tooth gear 4027 is sleeved on the other end of the worm gear 4023, and the other semi-tooth gear 4027 is sleeved on the outside of the transmission bevel gear rod 4022. One end of each of the two movable rods 4026 is installed at both ends of the reciprocating rack 4025, and a support sleeve is movably sleeved on the outside of each of the two movable rods 4026. The support sleeve is installed at the bottom of the fan frame 1031. When the servo motor 401 is powered on, it drives the de-icing bracket 403 to reciprocate rapidly via the reciprocating transmission assembly 402. Specifically, the rotational force of the servo motor 401 is transmitted to the transmission bevel gear 4022 and worm gear 4023 through the synchronous belt pulley 4021, driving the transmission bevel gear 4022 and worm gear 4023 to rotate. The transmission bevel gear 4022 and worm gear 4023 synchronously drive the two semi-toothed gear components 4027 to rotate. The reciprocating rack 4025 is driven by the synchronously rotating two semi-toothed gear components 4027. 27 Alternating meshing induces linear reciprocating motion. Both half-tooth gears 4027 cover half a circumference. One half-tooth gear 4027 meshes with and drives the reciprocating rack 4025, while the other half-tooth gear 4027 is not meshed with the reciprocating rack 4025. The two half-tooth gears 4027 rotate continuously, causing the reciprocating rack 4025 to be alternately pulled by the two half-tooth gears 4027. The movable rods 4026 at both ends of the reciprocating rack 4025 move back and forth along the support sleeve, realizing rapid axial reciprocating movement. Since the de-icing bracket 403 is fixedly connected to the movable rod 4026, the de-icing bracket 403 is driven to move back and forth quickly to continuously knock on multiple corrugated cooling fins in the evaporator 203, breaking the thin ice condensed on the multiple corrugated cooling fins in the evaporator 203, thus achieving the purpose of de-icing. Simultaneously running servo motor 401 transmits power to bevel gear transmission assembly 305 and worm gear transmission assembly 306 through reciprocating transmission assembly 402. Specifically, the rotational force of servo motor 401 is transmitted to transmission bevel gear rod 4022 and worm gear 4023 through synchronous belt pulley 4021, driving transmission bevel gear rod 4022 and worm gear 4023 to rotate. The rotating transmission bevel gear rod 4022 drives the meshing bevel gear transmission assembly 305 to rotate, and one end of the rotating bevel gear transmission assembly 305 drives the second dust removal assembly 302 to run by meshing with the second gear transmission assembly 304. The rotating worm 4023 drives the meshing worm gear transmission assembly 306 to rotate, and one end of the rotating worm gear transmission assembly 306 drives the first dust removal assembly 301 to run by meshing with the first gear transmission assembly 303. The first cleaning component 301 and the second cleaning component 302 clean the front and back of the air inlet condenser 201, the air outlet condenser 202, and the evaporator 203 to achieve self-cleaning of the air inlet condenser 201, the air outlet condenser 202, and the evaporator 203, and ensure the thermal conductivity of the air inlet condenser 201, the air outlet condenser 202, and the evaporator 203.

[0020] like Figures 8 to 9As shown, both the first dust removal assembly 301 and the second dust removal assembly 302 consist of a spline drive assembly, a lifting assembly, and two sets of rotating roller assemblies. The two ends of the two sets of rotating roller assemblies are respectively connected to the spline drive assembly and the lifting assembly, and the spline drive assembly and the lifting assembly are located at the two ends of the two sets of rotating roller assemblies. The spline drive assembly in the first dust removal assembly 301 is meshed with the first gear drive assembly 303, and the spline drive assembly in the second dust removal assembly 302 is meshed with the second gear drive assembly 304. The spline transmission assembly consists of two spline transmission rods 3011 and two spline bevel gears 3012. The bottom ends of the two spline transmission rods 3011 are fixedly connected to the top of the first gear transmission assembly 303. The first gear transmission assembly 303 drives the two spline transmission rods 3011 to rotate, and the rotating two spline transmission rods 3011 respectively drive the two spline bevel gears 3012 to rotate. The rotary roller assembly consists of two linked bevel gears 3013 and two cleaning rollers 3014. One end of each cleaning roller 3014 is fixedly mounted with a linked bevel gear 3013, which meshes with a splined bevel gear 3012. The splined bevel gear 3012 is movably connected to the splined bevel gear 3014 via a bearing bracket. The two rotating splined bevel gears 3012 drive the two linked bevel gears 3013 to rotate, and the two rotating linked bevel gears 3013 drive the corresponding two cleaning rollers 3014 to rotate, thus performing the cleaning operation. The lifting assembly consists of two lifting gears 3015, two racks 3016, two guide sleeves 3017, and two guide rods 3018. One end of each of the two lifting gears 3015 is fixedly mounted on the other end of each of the two cleaning rollers 3014. One end of each of the two guide sleeves 3017 is rotatably mounted on the other end of each of the two lifting gears 3015, and the two guide sleeves 3017 are movably sleeved on the outside of each of the two guide rods 3018. The two guide rods 3018 are fixedly mounted on the bottom of the fan frame 1031. The two racks 3016 are meshed with the two lifting gears 3015, and the two racks 3016 are fixedly mounted on the bottom of the fan frame 1031. The rotating cleaning rollers 3014 drive the lifting gears 3015 to rotate. The rotating lifting gears 3015 drive the cleaning rollers 3014 to move up and down through the racks 3016, and are guided by the guide sleeves 3017 moving outside the guide rods 3018, so that the cleaning rollers 3014 move up and down while rotating. It should be noted that the running servo motor 401 transmits power to the bevel gear transmission assembly 305 and the worm gear transmission assembly 306 via the reciprocating transmission assembly 402. The rotating bevel gear transmission assembly 305 drives the second dust removal assembly 302 through the second gear transmission assembly 304, which is meshed at one end. The rotating worm gear transmission assembly 306 drives the first dust removal assembly 301 through the first gear transmission assembly 303, which is meshed at one end. The first dust removal assembly 301 and the second dust removal assembly 302 operate synchronously. The first gear transmission assembly 303 drives the spline transmission assembly in the two dust removal assemblies 301 and 302 to operate synchronously, driving the two sets of rotating roller assemblies in the first dust removal assembly 301 and the second dust removal assembly 302 to rotate synchronously. The rotating roller assemblies are raised and lowered by the lifting assembly to achieve synchronous rotation of the two sets of rotating roller assemblies. The system performs a comprehensive cleaning of the inlet condenser 201, outlet condenser 202, and evaporator 203 by lifting and moving the rollers. Specifically, the first gear transmission assembly 303 drives two spline transmission rods 3011 to rotate. The two rotating spline transmission rods 3011 drive two spline bevel gears 3012 to rotate, and the two rotating spline bevel gears 3012 drive two linkage bevel gears 3013 to rotate. The two rotating linkage bevel gears 3013 drive two corresponding cleaning rollers 3014 to rotate. The two rotating cleaning rollers 3014 perform the cleaning work. At the same time, the two rotating cleaning rollers 3014 drive the lifting gear 3015 to rotate on one side of the rack frame 3016, thereby causing the cleaning rollers 3014 to move up and down. The guide sleeve 3017 moves and guides the rollers outside the guide rod 3018, so that the cleaning rollers 3014 move up and down while rotating.

[0021] like Figures 8 to 9 As shown, the first gear transmission assembly 303 consists of a first driving gear and two first driven gears. The two first driven gears are symmetrically installed on both sides of the first driving gear and mesh with both sides of the first driving gear. A first bevel gear is fixedly installed on the top of the first driving gear. It should be noted that the worm gear transmission assembly 306 transmits rotational power to the first driving gear through the first bevel gear. The rotating first driving gear drives the two first driven gears meshing on both sides to rotate. The top ends of the two first driven gears are fixedly connected to the bottom ends of the two splined transmission rods 3011 in the first dust removal assembly 301. Therefore, when the two first driven gears rotate, they can drive the two splined transmission rods 3011 to rotate synchronously, thereby driving the first dust removal assembly 301 to operate.

[0022] like Figure 8 , Figure 10As shown, the second gear transmission assembly 304 consists of a second driving gear and two second driven gears. The two second driven gears are symmetrically installed on both sides of the second driving gear and mesh with both sides of the second driving gear. A second bevel gear is fixedly installed on the top of the second driving gear. It should be noted that the bevel gear transmission assembly 305 transmits rotational power to the second driving gear through the second bevel gear. The rotating second driving gear drives the two second driven gears meshing on both sides to rotate. The top ends of the two second driven gears are fixedly connected to the bottom ends of the two spline transmission rods 3011 in the second dust removal assembly 302, respectively. Therefore, when the two second driven gears rotate, they can drive the two spline transmission rods 3011 to rotate synchronously, thereby driving the second dust removal assembly 302 to operate.

[0023] like Figures 8 to 9 As shown, the worm gear transmission assembly 306 consists of a first transmission rod, a worm gear, and a third bevel gear. The transmission rod is mounted on the top wall of the protective frame 1032 via two bearing brackets. The worm gear is fixedly mounted on one end of the transmission rod and meshes with the worm 4023. The third bevel gear is fixedly mounted on the other end of the transmission rod and meshes with the first bevel gear. It should be noted that the worm gear transmits the rotational force of the worm 4023 to the third bevel gear through the first transmission rod. The third bevel gear drives the first driving gear to rotate through the meshing first bevel gear. The rotating first driving gear drives the two first driven gears meshing on both sides to rotate synchronously.

[0024] like Figure 8 , Figure 10 As shown, the bevel gear transmission assembly 305 consists of a second transmission rod and two fourth bevel gears. The two fourth bevel gears are fixedly installed at both ends of the second transmission rod. The fourth bevel gear at one end of the second transmission rod meshes with the transmission bevel gear rod 4022, and the fourth bevel gear at the other end of the second transmission rod meshes with the second bevel gear. It should be noted that the transmission bevel gear rod 4022 transmits rotational force to one of the meshing fourth bevel gears, causing the fourth bevel gear to rotate. The fourth bevel gear then transmits the rotational force to another fourth bevel gear through the second transmission rod, driving the meshing second bevel gear to rotate, thus achieving the purpose of transmitting rotational power to the second gear transmission assembly 304.

[0025] like Figures 1 to 4 As shown, a top cabinet 101 is fixedly installed on the top of the dehumidifier cabinet 1, a cabinet door 102 is installed on the front of the dehumidifier cabinet 1 via a shaft bracket, and a water tank 104 is inserted and installed at the bottom inside the dehumidifier cabinet 1. It should be noted that the compressor 204 is located inside the top cabinet 101, which protects it from damage by moisture, dust, and external forces, ensuring the safety of the compressor 204. A controller is embedded in the front of the top cabinet 101, and the controller is electrically connected to the compressor 204 and the servo motor 401 via wires, facilitating the control of their operation. The cabinet door 102 is fixed to the front of the dehumidifier 1 by a threaded lock. When maintenance of the internal mechanism of the dehumidifier 1 is required, the threaded lock is released, and the cabinet door 102 is pulled outward via the shaft bracket for easy maintenance. A water level control valve is embedded in the back of the water tank 104, which can be connected to an external water pipe to discharge the water collected in the water tank 104, facilitating continuous collection of dehumidified water.
