[0002] Fresh air fans used in cold regions often experience local temperature differences when regulating temperature. The water temperature inside the circulating temperature regulation equipment is not uniform enough, and there is a lack of effective agitation or circulation structure, resulting in inconsistent water temperature, which affects the overall regulation effect. At the same time, the heat removal method is not reasonable, making it difficult to effectively improve the temperature uniformity inside the outer shell, resulting in poor temperature stability of the air delivered to the room. Furthermore, some existing equipment has limited filtration and purification capabilities for air treatment, low air circulation efficiency, and poor air flow from the fan. This not only makes it difficult to ensure the cleanliness of the output air, but also results in high energy loss due to poor structural coordination. This makes it impossible to simultaneously achieve the multiple requirements of efficient temperature regulation, energy conservation and consumption reduction, and air quality assurance when used in cold regions. Summary of the Invention

Some existing equipment has limited filtering and purification capabilities in air treatment, low air circulation efficiency, and poor effect of the fan in promoting air flow. Not only is it difficult to ensure the cleanliness of the output air, but the energy loss is also high due to poor structural coordination, and it is impossible to simultaneously achieve the multiple technical needs of efficient temperature regulation, energy saving and consumption reduction, and air quality assurance when used in cold areas.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a high-efficiency and energy-saving fresh air fan suitable for cold areas, comprising: an outer shell, a circulation temperature regulation device, a control valve, a sub-high-efficiency filter, a fan and an air outlet, the circulation temperature regulation device, the control valve, the sub-high-efficiency filter, the fan and the air outlet are respectively assembled in the inner cavity of the outer shell, the top two sides of the outer shell are respectively connected to the return air outlet and the fresh air outlet, and the inner cavity of the circulation temperature regulation device is connected to a bent pipe through the pump body.

A bearing with a seat is connected to the left side of the stirring rod. The bearing with a seat is arranged in the inner cavity of the circulation temperature control device. The bearing with a seat can support and fix the other end of the stirring rod, and cooperate with the sealed bearing to ensure the stability of the stirring rod during high-speed rotation, reduce shaking and wear, and ensure that the stirring effect is uniform and stable.

[0012] Preferably, a slot is provided on the top of the slotted block, and the outside of the circular arm is slidably connected to the inner cavity of the slot. When the circular arm rotates with the first conical tooth, its sliding in the slot can smoothly convert the circular motion into the linear reciprocating motion of the slotted block, ensuring the stability of the moving trajectory of the transmission part, and further ensuring the coordinated movement of the long connecting arm and the circulation pipe to avoid component jamming.

[0013] Preferably, the inner cavity of the protective shell is connected to a guide slide member, the top of the guide slide member is slidably connected to a track block, and the track block is connected to the slotted block. The guide slide member and the track block can limit and guide the movement direction of the slotted block to prevent it from offsetting and shaking during the reciprocating movement, ensuring that the driving force of the transmission member is stably transmitted to the long connecting arm, and the bottom of the guide slide member is connected to a reinforcing rib, which is connected to the inner cavity of the protective shell. The reinforcing rib can enhance the connection strength between the guide slide member and the protective shell, avoiding the guide slide member from loosening or deforming due to the repeated action of the slotted block, and ensuring the long-term stability of the guiding effect.

[0014] Preferably, a motor frame is provided on the outside of the motor, and the motor frame is connected to the inner cavity of the protective shell.

[0016] Preferably, the inner cavity of the outer shell is provided with a support frame, which is connected to the inner cavity of the outer shell through a damping rod. The top of the support frame is in contact with the bottom of the fan. The damping rod can absorb the vibration generated when the fan is running, reduce the noise generated by the vibration transmitted to the outer shell, and at the same time reduce the wear of the fan itself and surrounding components (such as sub-high efficiency filters, control valves) caused by vibration, thereby extending the overall service life of the equipment; the support frame provides stable support for the fan, ensuring that the fan is fixed in position during operation, and ensuring that the air supply direction and air volume are stable.

The outside of the fresh air outlet and the return air outlet are both provided with regulating valves. The regulating valves can flexibly adjust the amount of fresh air entering the fresh air outlet and the amount of return air circulation at the return air outlet according to the temperature difference between indoor and outdoor, air quality and other requirements. In cold areas, a large amount of low-temperature fresh air can be reduced from directly entering, reducing the heating load of the circulating temperature regulating equipment and achieving energy-saving effects.

[0018] Compared with the existing technology, the present invention provides a high-efficiency and energy-saving fresh air blower suitable for cold areas, which has the following beneficial effects: This energy-efficient, high-efficiency fresh air blower, suitable for cold regions, effectively improves temperature uniformity through the integration of a circulating temperature control device and a uniformity control mechanism. When the motor is activated, a stirring rod stirs the water inside the circulating temperature control device, helping to improve the consistency of the water temperature. Simultaneously, the flow tube, driven by the transmission element, further improves internal water temperature uniformity, preventing local temperature differences from affecting the regulation effect.

[0019] This energy-efficient fresh air blower, suitable for cold regions, uses the reciprocating motion of its piston rod, combined with components such as the air supply column, to extract and properly discharge heat from the circulating temperature-regulating device. This effectively improves the temperature uniformity within the outer shell and ensures a more stable temperature for the air delivered to the room. A sub-high-efficiency filter filters and purifies the air, ensuring the cleanliness of the output air. The return air vents and fresh air vents facilitate air circulation, while the fan efficiently promotes air flow. The overall structure works in tandem, effectively regulating air temperature while reducing energy loss, achieving high energy savings and ensuring the quality and temperature suitability of the output air when used in cold regions.

[0024] A uniform adjustment mechanism 3 is provided on the left side of the circulating temperature adjustment device 2. The circulating temperature adjustment device 2 is internally provided with temperature adjustment devices, such as a heater and a compressor. The heater can quickly increase the temperature of the circulating medium in cold regions, and the compressor can switch to a cooling mode according to demand, such as in transitional seasons, thus achieving multi-purpose use of one machine. A water source is provided in the inner cavity of the circulating temperature adjustment device 2. The water source can provide a basic carrier for the medium circulation, and the water source has been softened to reduce scale formation and avoid blockage of pipes such as the elbow 21 and the telescopic pipe 22. The inner cavity of the circulating temperature regulating device 2 is equipped with two sets of circulating water pumps, which are connected to the elbow 21. The two sets of circulating water pumps can work alternately or simultaneously. If one set fails, the other set can still maintain the medium circulation, thereby improving the reliability of the equipment. The inner cavity of the circulating temperature regulating device 2 is provided with a sensor, which can monitor the medium temperature, pressure and water level in real time. The data is fed back to the control system to achieve precise control of the heater, compressor and circulating water pump, thereby avoiding energy waste. A pressure relief valve is provided inside the circulation temperature regulating device 2. When the medium pressure exceeds the preset value, the pressure relief valve automatically opens to relieve the pressure, thereby preventing the elbow 21, the circulation pipe 23 and other pipelines from rupturing due to high pressure, and at the same time avoiding damage to the circulation water pump due to overload; the circulation temperature regulating device 2 is connected to the protective shell 25 through a heat-conducting copper plate, so that the heat of the circulation temperature regulating device 2 can be transferred to the inside of the protective shell 25, which can prevent the temperature of the inner cavity of the protective shell 25 from being too low in cold areas, and prevent the motor 31, bearings and other components of the uniform adjustment mechanism 3 from being poorly lubricated or having difficulty starting due to low temperature, thereby ensuring stable operation of the mechanism. Please refer to Figure 4 、 Figure 5 and Figure 6 The uniform adjustment mechanism 3 includes a motor 31, the output end of the motor 31 is connected to a first conical tooth 32, the outside of the first conical tooth 32 is connected to a second conical tooth 33, the first conical tooth 32 and the second conical tooth 33 adopt a high-precision meshing design, the transmission gap is small, the power transmission loss is reduced, and the driving force of the motor 31 is efficiently converted into the rotational force of the stirring rod 34; the outside of the second conical tooth 33 is connected to the stirring rod 34.

When the motor 31 drives the first conical tooth 32 to rotate, the circular arm 36 rotates with it, and then drives the transmission member 38 to move back and forth through the slotted block 37. The transmission member 38 pulls or pushes the long connecting arm 24, causing the flow tube 23 and the telescopic tube 22 to produce adaptive deformation, changing the flow velocity and flow path of the medium in the flow tube 23, avoiding local medium retention, and allowing the heat exchange between the medium and the air to be more sufficient. The deformation of the flow tube 23 can form a wavy path, prolonging the contact time between the medium and the air, and coordinating with the flow velocity change to enhance the turbulence effect, thereby further improving the heat exchange efficiency; the upper and lower sides of the transmission member 38 are rotatably connected to the linkage member 310.

When the transmission part 38 moves back and forth, the linkage part 310 drives the piston rod 311 to reciprocate and extend in the air supply column 312. Combined with the one-way flow characteristics of the first one-way valve tube 313 and the second one-way valve tube 314, the medium in the circulation temperature regulation equipment 2 can be pressurized or drained, the medium circulation can be accelerated, and the temperature regulation speed can be improved.

A slot is provided on the top of the slotted block 37, and the outer portion of the circular arm 36 is slidably connected to the inner cavity of the slot. When the circular arm 36 rotates with the first conical tooth 32, its sliding in the slot can smoothly convert the circular motion into the linear reciprocating motion of the slotted block 37, ensuring the stability of the moving trajectory of the transmission member 38, and thus ensuring the coordinated movement of the long connecting arm 24 and the circulation tube 23 to avoid component jamming. The inner wall of the slot is provided with a wear-resistant coating such as polytetrafluoroethylene to reduce the friction coefficient between the circular arm 36 and the slotted block 37, making the motion conversion smoother and reducing energy loss.

The movement of the transmission member 38 drives the piston rod 311 to reciprocate through the linkage member 310, and cooperates with the air supply column 312 and the second one-way valve pipe 314 to extract the heat inside the circulation temperature regulation device 2 and then discharge it through the first one-way valve pipe 313, thereby improving the uniformity of the temperature inside the outer shell 1.
