DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] Please refer to Figures 1-3 , the present utility model provides the following technical solutions: A cryogenic air-cooled heat pump unit includes a chassis 1, a compressor 3 is arranged inside the chassis 1, an evaporator 2 is arranged on the top of the compressor 3, an air guide duct 10 is arranged on the top surface of the chassis 1, a suction air duct 9 is arranged on one side surface of the air guide duct 10, an annular valve flap 8 is arranged on the top surface of the air guide duct 10, a rotating rod 7 is arranged on one side of the annular valve flap 8, a servo motor 6 is arranged at one end of the rotating rod 7, a sound insulation component 4 is arranged on one side surface of the chassis 1, and a filtration and purification component 5 is arranged inside the air guide duct 10.

[0024] Specifically, the sound insulation component 4 includes a hinge 41, a sealing strip 42, a sound insulation cotton 43, a plastic sound insulation film 44, a sound insulation board 45, a heating port 46, a torsion block 47, a handle 48 and a sound insulation glass 49. Among them, a sound insulation cotton 43 is arranged on one side of the compressor 3, a plastic sound insulation film 44 is arranged on one side surface of the sound insulation cotton 43, a sealing strip 42 is arranged on the top of the sound insulation cotton 43, a sound insulation board 45 is arranged on the side of the sound insulation cotton 43 away from the compressor 3, a heating port 46 is arranged on the surface of the sound insulation board 45, a sound insulation glass 49 is arranged on the top of the heating port 46, a handle 48 is arranged on one side of the sound insulation glass 49, a torsion block 47 is arranged on one side of the handle 48, and a hinge 41 is arranged on the side surface of the chassis 1 away from the torsion block 47.

[0025] By adopting the above technical solution, when the unit is running, the noise generated by the compressor 3 first undergoes the first layer of sound insulation through the plastic sound insulation film 44. The sound insulation board 45 arranged on one side of the chassis 1 conducts the second layer of sound insulation on the noise generated by the compressor 3. At the same time, the sound insulation cotton 43 arranged at the contact position between the chassis 1 and the sound insulation board 45 can effectively isolate the noise. The sealing strip 42 arranged on one side of the evaporator 2 can effectively seal the evaporator 2 and prevent heat loss during the operation of the evaporator 2. When it is necessary to overhaul the unit, only the torsion block 47 needs to be rotated to cancel the limit of the sound insulation board 45 by the torsion block 47, and then the sound insulation board 45 can be rotated and opened through the hinge 41. This process not only solves the problem that the noise generated during the operation of the unit affects people's normal life, but also improves the working efficiency of the evaporator 2. At the same time, it also facilitates the operator to overhaul the unit, improves the practicability of the unit, and is suitable for wide promotion.

[0026] Specifically, a rotating shaft is arranged inside the torsion block 47.

[0027] By adopting the above technical solution, the limiting work of the torsion block 47 on the sound insulation board 45 is simplified, and the practicability of the component is improved.

[0028] In the use of this embodiment: When the unit is operating, the noise generated by the compressor 3 first undergoes primary sound insulation through the plastic sound insulation film 44. The sound insulation board 45 provided on one side of the chassis 1 conducts secondary sound insulation on the noise generated by the compressor 3. At the same time, the sound insulation cotton 43 provided at the contact between the chassis 1 and the sound insulation board 45 can effectively isolate the noise. The sealing strip 42 provided on one side of the evaporator 2 can effectively seal the evaporator 2 to prevent heat loss during the operation of the evaporator 2. When the unit needs to be repaired, only need to rotate the torsion block 47 to cancel the limit on the sound insulation board 45, and then rotate and open the sound insulation board 45 through the hinge 41. This process not only solves the problem that the noise generated during the operation of the unit affects people's normal life, but also improves the working efficiency of the evaporator 2. At the same time, it also facilitates the operator to repair the unit, improves the practicability of the unit, and is suitable for wide promotion. By arranging a rotating shaft inside the torsion block 47, the limiting work of the torsion block 47 on the sound insulation board 45 is simplified, and the practicability of the component is improved.

[0029] Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is as follows: Specifically, the filter purification component 5 includes a pull ring 51, a sealing ring 52, a filter housing 53, an activated carbon layer 54, an ultraviolet disinfection lamp 55, an inner protection net 56, a filter net 57, a through-hole plate 58, and a limiting block 59. Among them, a filter housing 53 is arranged inside the air duct 10. A sealing ring 52 is arranged on the top of the filter housing 53. A limiting block 59 is arranged on the top surface of the sealing ring 52. A pull ring 51 is arranged inside the limiting block 59. An activated carbon layer 54 is arranged at the bottom of the filter housing 53. An ultraviolet disinfection lamp 55 is arranged inside the filter housing 53. An inner protection net 56 is arranged on one side of the ultraviolet disinfection lamp 55. A filter net 57 is arranged on the side of the inner protection net 56 away from the ultraviolet disinfection lamp 55. A through-hole plate 58 is arranged on the surface of the filter net 57.

[0031] By adopting the above technical solution, when the temperature of the unit is too low during operation and it is necessary to extract indoor air for compression heating, the air first enters the surface of the ultraviolet disinfection lamp 55 inside the filter housing 53 through the air suction pipe 9 to disinfect the inhaled air, and then passes through the inner protection net 56 to filter larger particles and foreign matters in the air, and then passes through the filter net 57 to finely filter the air. After the filtration is completed, it is discharged from the through-hole plate 58, and finally passes through the activated carbon layer 54 to remove the peculiar smell and harmful substances in the air, and then is sent into the unit. When the unit extracts outdoor air for compression heating during operation, it also needs to go through the above filtration process, but the impurities and foreign matters filtered out will fall on the surface of the cleaning plate at the bottom of the ultraviolet disinfection lamp 55. When it is necessary to replace the filter material and clean the impurities, only need to pull the pull ring 51 to take out the through-hole plate 58 and the cleaning plate. This solves the problem that indoor air cannot exchange gas with the outside air, which will cause indoor air to become turbid after a long time, and it is also impossible to ensure the air quality when extracting outdoor air, which is not conducive to human health. At the same time, it also facilitates the operator to clean the impurities and foreign matters filtered out, improves the heating quality of the unit, ensures the comfort of heating, and improves the practicality of the unit.

[0032] Specifically, a cleaning plate is provided at the bottom of the ultraviolet disinfection lamp 55.

[0033] By adopting the above technical solution, it is convenient for the operator to clean the impurities and foreign matters that cannot pass through the filter net 57 in time, and improves the practicality of the component.

[0034] Specifically, a limiting column is provided at the contact surface between one end of the pull ring 51 and one side surface of the limiting block 59.

[0035] By adopting the above technical solution, it is avoided that during the process of lifting the pull ring 51, the two ends of the pull ring 51 are disengaged from the inside of the limiting block 59, resulting in the pull ring 51 being unable to be used normally and reducing the practicality of the component.

[0036] When this embodiment is in use: when the temperature is too low during operation of the unit and indoor air needs to be extracted for compression and heating, the air first passes through the suction pipe 9 and enters the surface of the ultraviolet disinfection lamp 55 inside the filter housing 53 to disinfect the inhaled air, and then passes through the inner protective net 56 to filter larger particles and foreign matter in the air, and then passes through the filter net 57 to filter the air carefully. After the filtration is completed, it is discharged from the through-hole plate 58, and finally passes through the activated carbon layer 54 to remove the odor and harmful substances in the air, and then is sent into the interior of the unit. When the unit is running and outdoor air is extracted for compression and heating, it also needs to go through the above-mentioned filtration process, but the impurities and foreign matter filtered out will fall on the surface of the cleaning plate at the bottom of the ultraviolet disinfection lamp 55. When it is necessary to replace the filter material and clean the impurities, it is only necessary to pull the pull ring 51 to remove the through-hole plate 58. The cleaning plate solves the problem that the indoor air cannot exchange gas with the outside air, which will cause the indoor air to be turbid for a long time and the air quality cannot be guaranteed when extracting outdoor air, which is not conducive to human health. At the same time, it also facilitates the operator to clean the filtered impurities and foreign matter, improves the heating quality of the unit, ensures the comfort of heating, and improves the practicality of the unit. By arranging a cleaning plate at the bottom of the ultraviolet disinfection lamp 55, it is convenient for the operator to clean the impurities and foreign matter that cannot pass through the filter 57 in time, thereby improving the practicality of the component. By arranging a limit column at the contact point between one end of the pull ring 51 and the surface of one side of the limit block 59, it is avoided that the two ends of the pull ring 51 are separated from the inside of the limit block 59 during the pulling process of the pull ring 51, thereby causing the pull ring 51 to be unable to be used normally, thereby reducing the practicality of the component.

[0037] The ultraviolet disinfection lamp 55 of the present invention is an existing disclosed technology, and the selected model is TUV16W4PSE.

[0038] The structure and operating principle of the evaporator 2, compressor 3, servo motor 6 and annular valve flap 8 in the present invention have been disclosed in an ultra-low temperature air-cooled heat pump unit disclosed in Chinese patent application No. 202322806931.8.

[0039] Working principle and usage process of the present utility model: The present utility model adjusts the ultra-low temperature air-cooled heat pump unit. When the unit is operating, the noise generated by the compressor 3 first undergoes the first layer of sound insulation through the plastic sound insulation film 44. The sound insulation board 45 arranged on one side of the chassis 1 conducts the second layer of sound insulation for the noise generated by the compressor 3. Meanwhile, the sound insulation cotton 43 arranged at the contact between the chassis 1 and the sound insulation board 45 can effectively isolate the noise. The sealing strip 42 arranged on one side of the evaporator 2 can effectively seal the evaporator 2 to prevent heat loss during the operation of the evaporator 2. When the unit needs to be overhauled, only need to rotate the torsion block 47 to cancel the limit of the sound insulation board 45 by the torsion block 47, and then rotate and open the sound insulation board 45 through the hinge 41. This process not only solves the problem that the noise generated during the operation of the unit affects people's normal life, but also improves the working efficiency of the evaporator 2. At the same time, it also facilitates the maintenance work of the unit by the operator, improves the practicality of the unit, and is suitable for wide promotion. By arranging a rotating shaft inside the torsion block 47, the limit work of the torsion block 47 on the sound insulation board 45 is simplified, and the practicality of the component is improved. The present utility model adjusts the ultra-low temperature air-cooled heat pump unit. When the temperature is too low during the operation of the unit and indoor air needs to be extracted for compression and heating, the air first enters the surface of the ultraviolet disinfection lamp 55 inside the filter housing 53 through the air suction pipe 9 to disinfect the inhaled air, and then passes through the inner protection net 56 to filter larger particles and foreign matters in the air, and then passes through the filter net 57 to conduct a detailed filtration of the air. After the filtration is completed, it is discharged from the through-hole plate 58, and finally passes through the activated carbon layer 54 to remove the peculiar smell and harmful substances in the air, and then is sent into the unit. When the unit extracts outdoor air for compression and heating during operation, the same filtration process is required, but the filtered impurities and foreign matters will fall on the surface of the cleaning plate at the bottom of the ultraviolet disinfection lamp 55. When it is necessary to replace the filter material and clean the impurities, only need to pull the pull ring 51 to take out the through-hole plate 58 and the cleaning plate. This solves the problem that indoor air cannot exchange gas with the outside air, which will cause indoor air to become turbid after a long time, and the quality of the air cannot be guaranteed when extracting outdoor air, which is not conducive to human health. At the same time, it also facilitates the cleaning work of the impurities and foreign matters filtered by the operator, improves the heating quality of the unit, ensures the comfort of heating, and improves the practicality of the unit. By arranging a cleaning plate at the bottom of the ultraviolet disinfection lamp 55, it is convenient for the operator to clean the impurities and foreign matters that cannot pass through the filter net 57 in time, and improves the practicality of the component. By arranging a limit post at the contact between one end of the pull ring 51 and the surface of one side of the limit block 59, it is avoided that the two ends of the pull ring 51 break away from the inside of the limit block 59 during the lifting process of the pull ring 51, resulting in the inability to use the pull ring 51 normally and reducing the practicality of the component.

[0040] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
