[0046] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0047] In combination Figures 1 to 15 As shown in the drawings, the embodiment of the present disclosure provides a connecting pipe 90, such as Figures 2 to 3 As shown in the drawings, the connecting pipe 90 includes a first pipe 91 and a hood 93, the first pipe 91 has a cross section in a central symmetric shape; the hood 93 is arranged at a first port 911 of the first pipe 91, the first port 911 is adapted to communicate with the outside, the hood 93 has a first end 931 and a second end 932, the second end 932 is connected with the first pipe 91; wherein the first end 931 is spirally coiled, and the spiral diameter of the first end 931 gradually decreases in the direction away from the pipe.

[0048] In the embodiment of the present disclosure, the first pipe 91 of the connecting pipe 90 communicates with the outside, that is, the first port 911 of the first pipe is used for the new air to flow into or exhaust the turbid air in the room, the cross section of the first pipe 91 is in a central symmetric shape, so that the air inlet and outlet of the first pipe 91 is more uniform, and the airflow velocity in the first pipe 91 is also more uniform, which improves the flow rate of the airflow, reduces the resistance, and improves the air volume. The first end 931 is spirally coiled, and the spiral diameter of the first end 931 gradually decreases in the direction away from the pipe, so that the airflow can be guided to flow into the first pipe 91, the smoothness of the airflow is improved, the air volume loss is reduced, and the spiral hood 93 can filter the impurities such as particulate matters in the airflow to avoid the blockage of the connecting pipe 90.

[0049] Optionally, the connecting pipe 90 is a fresh air pipe or a drain pipe.

[0050] Optionally, the hood 93 is a metal wire. In order to facilitate the processing and installation of the hood.

[0051] Optionally, the cross section of the first pipe 91 is in an elliptical shape. The elliptical shape is a central symmetric figure which is mutually symmetric in the major axis and the minor axis, so that the space occupied by the first pipe 91 can be reduced, the air inlet smoothness of the first pipe 91 can be further improved, the air resistance can be reduced, the air volume can be improved, the airflow uniformity can be improved, and the elliptical structure is more smooth, which facilitates the airflow flow and reduces the airflow loss.

[0052] Optionally, the spiral diameter of the first end 931 gradually decreases in the direction away from the first pipe 91 to form a tapered portion, and the tip of the tapered portion is located on the extension line of the central axis of the first pipe 91. That is, the first end 931 is in a spiral tapered structure.

[0053] In the embodiment of the present disclosure, the tip of the first end portion 931 is located on the central axis of the first pipeline 91, so that the spiral first end portion 931 can uniformly guide the airflow into the first pipeline 91, further improving the uniformity of the airflow in and out. And, the centrifugal force can be generated at the center of the first pipeline 91, uniformly filtering the impurities of the first port 911, avoiding uneven filtering.

[0054] Optionally, the first end portion 931 protrudes from the first port 911. In this way, the installation of the air cap 93 is facilitated, and the guiding effect can be provided outside the first port 911 to make the airflow flowing into the first pipeline 91 more smooth and uniform.

[0055] Optionally, the spiral pitch of the first end portion 931 is uniformly arranged. In this way, the airflow can be smoothly and uniformly guided into the first pipeline 91, reducing the turbulence and energy loss of the airflow, and improving the flow efficiency of the airflow. In addition, the uniform spiral structure can also enhance the mechanical strength and stability of the air cap 93, so that it can still maintain good protection performance in harsh weather conditions (such as strong wind or heavy rain), preventing foreign matter or rain from directly entering the pipeline. In addition, the uniform spiral pitch helps to generate a consistent centrifugal effect when the airflow enters, further improving the separation effect of particulate matter in the airflow and improving air quality.

[0056] Optionally, as shown in Figure 2 the second end portion 932 is spirally arranged outside the first pipeline 91. In the embodiment of the present disclosure, the spirally arranged second end portion 932 enhances the connection strength and sealing performance between the air cap 93 and the pipeline, effectively preventing airflow leakage or external foreign matter intrusion, and ensuring the purity and efficient flow of the airflow. At the same time, the spiral structure forms a protective barrier outside the first pipeline 91, which can disperse external wind pressure or impact force, and improve the durability and wind resistance of the air cap 93.

[0057] Optionally, the connecting pipe 90 further comprises a fixing device 94, which is attached to the outside of the second end portion 932 for fixing the second end portion 932.

[0058] In the embodiment of the present disclosure, the fixing device 94 further enhances the stability and practicability of the air cap 93. The fixing device 94 can firmly fix the second end portion 932 outside the first pipeline 91, preventing the loosening or falling off of the air cap 93 due to wind pressure, vibration or external impact, and ensuring the long-term stability of the connection between the air cap 93 and the first pipeline 91.

[0059] Optionally, the fixing device 94 can be a pasting type fixing device such as adhesive tape, or a buckle type fixing device, a bolt type fixing device, a hoop type fixing device, and a magnetic type fixing device, etc. Preferably, the fixing device 94 is a pasting type fixing device, which has a lower cost and is convenient to install and disassemble.

[0060] Optionally, the first conduit 91 is made of a rigid polymer material.

[0061] In this embodiment, the first duct 91 is made of a rigid polymer material. Rigid polymer materials are characterized by high strength, corrosion resistance, and lightweight, enabling the first duct 91 to effectively resist chemical corrosion, humidity changes, and ultraviolet radiation in the environment while ensuring structural stability, thus extending its service life. Furthermore, the smooth surface of the rigid polymer material reduces frictional resistance during airflow, lowers energy loss, and improves ventilation efficiency.

[0062] Optionally, the first conduit 91 is made of rigid PVC (polyvinyl chloride) or PP (polypropylene), etc.

[0063] Optionally, such as Figure 1 As shown, the first pipe 91 is adapted to penetrate the installation base 100. The first pipe 91 also includes a second port, which is arranged opposite to the first port 911. The connecting pipe 90 also includes a second pipe 92, one end of which is adapted to be detachably connected to the second port, and the other end is used to connect to the fresh air inlet 101 or the stale air outlet 105 of the air conditioning equipment.

[0064] In this embodiment, the first pipe 91 is installed within the mounting base 100, and the second pipe 92 can be connected to or disconnected from the first pipe 91. This facilitates the overall transportation and installation of the connecting pipe 90, and also enables the installation of the connecting pipe 90.

[0065] Optionally, the installation base 100 can be a wall, ceiling, or other cabinet or other structure through which pipes such as connecting pipe 90 pass.

[0066] Optionally, such as Figures 4 to 7 As shown, the second pipe 92 can be sleeved on the outside of the first pipe 91 and detachably connected to the first pipe 91; wherein, when the first pipe 91 is inserted into the second pipe 92, the second pipe 92 can deform and fit against the outer wall of the first pipe 91.

[0067] The first pipe 91 and the second pipe 92 of the connecting pipe 90 are detachably connected, so that the flexibility and convenience of installation of the connecting pipe 90 are improved. When the first pipe 91 is inserted into the second pipe 92, the second pipe 92 can be deformed and fit on the outside of the first pipe 91, so that the connection sealing property of the first pipe 91 and the second pipe 92 is enhanced, air leakage is prevented, the stability of the connecting pipe 90 as a whole is improved, and vibration or external impact can be effectively resisted. In this way, the installation and dismounting of the first pipe 91 and the second pipe 92 are facilitated, no additional components are needed, the cost is reduced, and through the connection mode of the first pipe 91 and the second pipe 92, the connecting pipe 90 can not only pass through one wall, but also pass through multiple walls, without the need for additional conversion structures, the components are greatly reduced, and the cost is reduced.

[0068] Optionally, the first pipe 91 is made of a hard material, and the second pipe 92 is made of a deformable flexible material.

[0069] In the embodiment of the present disclosure, the first pipe 91 made of a hard material provides high strength and stability, can effectively support the overall structure and ensure the efficiency of air flow transmission, and resist external impact and pressure. The second pipe 92 made of a deformable flexible material can be elastically deformed when sleeved, tightly fit on the outer wall surface of the first pipe 91, form a high-sealing connection, and prevent air leakage. Moreover, the first pipe 91 and the second pipe 92 adopt the above-mentioned materials, facilitating the connection of the first pipe 91 and the second pipe 92, without the need for an additional conversion head, and can be quickly installed and dismounted. In this way, not only is the connecting pipe 90 convenient to pass through one wall, but also is more convenient to connect when passing through multiple walls, compared with the connecting pipe 90 provided with a conversion head, and the cost is also lower.

[0070] Optionally, the material of the first pipe 91 is selected from hard polymer materials, including polyvinyl chloride, polypropylene or a combination thereof; and / or the material of the second pipe 92 is selected from flexible polymer materials, including polyethylene, thermoplastic elastomer or a combination thereof.

[0071] In the embodiment of the present disclosure, the first pipe 91 made of a hard polymer material has high strength, corrosion resistance and environmental resistance, can provide stable structural support and ensure the efficiency of air flow transmission, and resist external impact and pressure. The second pipe 92 made of a flexible polymer material has good elasticity and deformation ability, can tightly fit the outer wall surface of the first pipe 91 when sleeved, form a high-sealing connection, and prevent air leakage. Moreover, the first pipe 91 and the second pipe 92 adopt the above-mentioned materials, the cost is relatively low, and the service life is long.

[0072] Optionally, the inner wall surface of the second pipe 92 is provided with an anti-skid thread to increase the friction force at the connection between the first pipe 91 and the second pipe 92.

[0073] In the embodiments of the present disclosure, after the first pipeline 91 is inserted into the second pipeline 92, the inner wall surface of the second pipeline 92 is provided with an anti-skid thread, so that the friction between the first pipeline 91 and the second pipeline 92 is increased, the first pipeline 91 and the second pipeline 92 are prevented from being separated, and the connection stability of the first pipeline 91 and the second pipeline 92 is improved. The threaded connection can also enhance the sealing between the two pipelines, prevent air leakage, and improve the ventilation efficiency.

[0074] Optionally, the second pipeline 92 is a threaded hose 921. In this way, the friction between the first pipeline 91 and the second pipeline 92 can be increased, and the fit of the first pipeline 91 and the second pipeline 92 can be ensured. In addition, the flexible nature of the second pipeline 92 can further adapt to first pipelines 91 of different sizes or shapes, simplifying the installation process and improving the versatility of the system.

[0075] Optionally, as shown in Figure 6 The connection pipe 90 also includes a heat preservation layer 922, which is sleeved on the outside of the second pipeline 92. The heat preservation layer 922 can effectively reduce the heat loss of the outside of the second pipeline 92 or the influence of the outside temperature on the airflow in the second pipeline 92, ensure that the airflow maintains a stable temperature during transmission, and thus improve the energy efficiency of the ventilation system. In cold environments, the heat preservation layer 922 can prevent the temperature of the airflow in the second pipeline 92 from being too low, avoiding condensation or icing phenomena. In high-temperature environments, the heat preservation layer 922 can block external heat and maintain the cool state of the airflow. In addition, the heat preservation layer 922 can also reduce the risk of condensation on the outer surface of the pipeline and prevent water accumulation from corroding the pipeline material, prolonging the service life.

[0076] Optionally, the heat preservation layer 922 is heat preservation cotton or heat preservation adhesive tape, etc.

[0077] Optionally, as shown in Figure 4 The cross section of the first pipeline 91 is oval, and the cross section of the second pipeline 92 is circular.

[0078] In the embodiments of the present disclosure, the oval first pipeline 91 can provide a larger effective ventilation area, optimize the airflow transmission efficiency, and at the same time, its flat structure facilitates installation in limited space, saving occupied space. The circular second pipeline 92 has good structural strength and uniform stress distribution, can effectively resist the impact of external pressure and airflow, and ensure the stability and sealing of the connection. In addition, the circular cross section of the second pipeline 92 can tightly fit the outer wall surface of the first pipeline 91 when it is sleeved with the oval first pipeline 91, forming a high-sealing connection to prevent air leakage.

[0079] Optionally, when the second pipe 92 remains unchanged, the length of the major axis of the cross-section of the first pipe 91 is greater than the outer diameter of the cross-section of the second pipe 92.

[0080] In this embodiment, the elliptical cross-section of the first conduit 91 has a longer major axis, which allows it to deform appropriately when the second conduit 92 is inserted, thereby tightly fitting against the outer wall of the first conduit 91 and forming a highly airtight connection. Furthermore, the longer major axis of the first conduit 91 increases its flow area.

[0081] Optionally, the outer wall of the first pipe 91 is provided with a positioning mark, which corresponds to the second pipe 92 when the first pipe 91 is inserted into a preset position in the second pipe 92.

[0082] In this embodiment of the present disclosure, the positioning mark can intuitively indicate the preset position of the first pipe 91 inserted into the second pipe 92, ensuring that the installer can complete the connection quickly and accurately, and avoid airflow leakage or unstable connection caused by insertion that is too deep or too shallow.

[0083] Optionally, the outer wall of the first conduit 91 is provided with a limiting protrusion. When the first conduit 91 is inserted into a preset position in the second conduit 92, the limiting protrusion and the second conduit 92 are limited to prevent the first conduit 91 from being inserted further into the second conduit 92. The limiting protrusion prevents the first conduit 91 from being over-inserted into the second conduit 92 by physically limiting it, ensuring the accuracy and consistency of the connection position, and enhancing the stability of the connection.

[0084] Optionally, such as Figure 1 As shown, when there are multiple mounting bases 100, each mounting base 100 is provided with at least one first pipe 91, and a second pipe 92 is connected to one or both ends of a first pipe 91 so that the connecting pipe 90 passes through the mounting base 100.

[0085] In this embodiment of the present disclosure, when the connecting pipe 90 needs to pass through the mounting base 100, each mounting base 100 is provided with at least one first pipe 91, and a second pipe 92 is connected to one or both ends of a first pipe 91, which facilitates the connection pipe 90 passing through the wall. Moreover, with this configuration, the connecting pipe 90 is suitable for installation in complex environments, can pass through multiple walls, and can accommodate single-wall, double-wall, or multi-wall situations.

[0086] This disclosure also provides a piping assembly, wherein the air conditioning device includes a connecting pipe 90 as described in any of the above embodiments.

[0087] This disclosure provides a pipeline assembly that includes the connecting pipe 90 of any of the above embodiments, and therefore has the beneficial effects of the connecting pipe 90 of any of the above embodiments, which will not be repeated here.

[0088] Optionally, as shown in Figure 8 The installation base 100 is also provided with a reserved hole 11, and the pipeline assembly further comprises an integrated pipeline 95 located on one side of the first pipeline 91, the integrated pipeline 95 comprising a refrigerant pipeline, a drainage pipeline 953 and an online line 954; wherein the integrated pipeline 95 and the first pipeline 91 can be integrated and pass through one reserved hole 11.

[0089] In the embodiment of the present disclosure, the reserved hole 11 on the installation base 100 can accommodate the first pipeline 91 of the connecting pipeline 90 and the integrated pipeline 95 comprising the refrigerant pipeline, the drainage pipeline 953 and the online line 954 at the same time, so that the reserved hole 11 can be used to simultaneously arrange multiple pipelines related to the air conditioning equipment, and the integrated design reduces the number of openings on the installation base 100 or structure, and there is no need to expand the area of the reserved hole 11, which simplifies the installation and assembly process, and reduces the construction difficulty and cost. The first pipeline 91 adopts an elliptical cross section, which not only optimizes the airflow transmission efficiency, but also saves the occupied space and facilitates integration with other pipelines. The integrated pipeline 95 integrates the refrigerant pipeline, the drainage pipeline 953 and the online line 954 together, which ensures the coordination and stability of each functional pipeline, and reduces the interference between the pipelines.

[0090] Optionally, the pipeline assembly further comprises a connecting piece capable of integrally connecting the connecting pipeline 90 and the integrated pipeline 95; wherein the integrated pipeline 95 and the first pipeline 91 can pass through one reserved hole 11 after being integrated.

[0091] In the embodiment of the present disclosure, the connecting pipeline 90 and the integrated pipeline 95 are connected and fixed together by the connecting piece, and the axes of the connecting pipeline 90 and the integrated pipeline 95 are arranged side by side in the reserved hole 11, so that the connecting pipeline 90 and the integrated pipeline 95 can be more stably connected, which facilitates the pipeline assembly to pass through the reserved hole 11 and facilitates the assembly and installation of the pipeline assembly.

[0092] Optionally, the connecting piece is a binding rope or a binding tape, etc., which is low in cost and easy to operate. Alternatively, the connecting piece can also be a buckle fixing piece or a pasting type fixing belt, etc.

[0093] Optionally, part of the outer wall surface of the integrated pipeline 95 or part of the outer wall surface of the first pipeline 91 is adapted to be tangent to the inner wall surface of the reserved hole 11.

[0094] In the embodiments of the present disclosure, the outer wall surface of part of the integrated pipeline 95 or the outer wall surface of part of the first pipeline 91 is tangent to the inner wall surface of the reserved hole 11, so that the installation stability and sealing performance of the pipeline assembly are improved. The tangent fitting mode can make the pipeline assembly closely fit the inner wall surface of the reserved hole 11, reduce the installation gap between the pipeline assembly and the reserved hole 11, prevent air flow, liquid or noise leakage, and improve the overall structural stability of the pipeline assembly. It can also disperse external pressure or vibration and improve stability.

The lower position of the drain pipe 953 and the thick copper pipe 951 facilitates natural discharge of condensate water and efficient transmission of refrigerant, ensuring stable operation of the system. This layered arrangement not only makes full use of the vertical space, but also simplifies the pipeline layout, facilitates installation and maintenance, and facilitates the circulation of refrigerant, water and fresh air.

[0099] Optionally, the pipeline assembly further comprises a foam 96, which is arranged in the gap between the drain pipe 953, the thick copper pipe 951, the thin copper pipe 952 and the first pipeline 91. The foam 96 can effectively fill the gap between the pipeline assembly, reduce vibration transmission and noise generation, and improve the quiet performance of the system. At the same time, the foam 96 has good heat preservation performance, which can prevent the refrigerant pipe and the drain pipe 953 from causing energy loss or condensate icing due to temperature changes, thereby improving the energy efficiency and reliability of the system. In addition, the foam 96 can also fix the position of each pipeline, prevent displacement of the pipeline caused by vibration or external impact, and enhance the stability of the overall structure of the pipeline assembly.

[0101] In the embodiment of the present disclosure, the online line 954 is relatively thin, and the online line 954 is arranged on one side of the integrated pipeline 95, so that the online line 954 is not arranged between multiple pipelines, thereby reducing the influence of the temperature of the refrigerant pipe or the condensate outside the pipeline on the online line 954, and ensuring the normal operation of the online line 954.

[0102] Optionally, the pipeline assembly further comprises a waterproof sealing member, which is arranged between the integrated pipeline 95 and the inner wall surface of the reserved hole 11, and / or is arranged between the first pipeline 91 and the inner wall surface of the reserved hole 11. In the embodiment of the present disclosure, the waterproof sealing member is arranged outside the integrated pipeline 95 or the first pipeline 91, so that the waterproof sealing member can prevent the refrigerant pipe and the drain pipe 953 from causing energy loss or condensate icing due to temperature changes, thereby improving the energy efficiency and reliability of the system. In addition, the waterproof sealing member can effectively prevent water, dust or other foreign matters from entering the inside of the pipeline through the reserved hole 11, thereby avoiding corrosion or pollution of the pipeline assembly and prolonging the service life of the system. At the same time, the waterproof sealing member can also enhance the connection stability between the pipeline assembly and the reserved hole 11, reduce loosening or displacement caused by vibration or external impact, and ensure long-term stable operation of the pipeline assembly. In addition, the waterproof sealing member can also improve the sound insulation performance of the pipeline assembly, reduce noise leakage, and improve the use environment.

[0103] Optionally, the center of the thin copper pipe 952 is on one side of the center of the first pipeline 91, so as to reduce the size of the pipeline assembly in the height direction, thereby facilitating more reasonable arrangement of multiple pipelines in the reserved hole 11.

[0104] Optionally, the equivalent circular tube diameter of the first pipeline 91 is greater than or equal to 37 mm.

[0105] The equivalent circular tube diameter refers to converting the cross-sectional area of a non-circular tube or channel into the diameter of a circular tube with the same flow characteristics. In the embodiments of the present disclosure, the diameter of the conventional connecting pipe 90 is generally between 30-33mm, and the equivalent circular tube diameter of the first pipe 91 is greater than or equal to 37mm, so that the flow area of the connecting pipe 90 of the embodiments of the present disclosure is larger than that of the conventional connecting pipe 90, which can improve the air volume of the connecting pipe 90, and further improve the air volume of the air conditioning equipment. The connecting pipe 90 of the embodiments of the present disclosure is provided in an elliptical shape, which can increase the flow area in the pipe without increasing the size, thereby reducing the resistance and improving the air volume.

[0106] Optionally, the length of the minor axis of the first pipe 91 is greater than or equal to 30.5mm; and / or, the length of the major axis of the first pipe 91 is greater than or equal to 55.3mm.

[0112] The embodiments of the present disclosure provide an air conditioning equipment, which comprises the connecting pipe 90 of any one of the above embodiments, and thus has the beneficial effects of the connecting pipe 90 of any one of the above embodiments, which will not be described herein.

[0113] Optionally, as Figures 9 to 15As shown, the air conditioning device further comprises a device body, the device body comprising a shell 10 and a fan located in the shell 10, the shell 10 being provided with a fresh air inlet 101 or a turbid air outlet 105; the inlet end of the connecting pipe 90 is in communication with the fresh air inlet 101 or the turbid air outlet 105. The device body comprises an air conditioner module in communication with the refrigerant pipe. The device body comprises a water pan in communication with the drain pipe 953. The device body is electrically connected with the online line 954.

[0114] Optionally, the air conditioning device can be an air conditioner, a fresh air machine or an air conditioner integrated with a fresh air function.

[0115] Optionally, the air conditioner can be a cabinet type air conditioner.

[0116] Optionally, as shown, Figure 14 the connecting pipe 90 comprises a fresh air outlet pipe 702 in communication with the turbid air outlet 105, wherein the inner wall surface of the turbid air outlet 105 is provided with an internal thread, the outer wall surface of the fresh air outlet pipe 702 is provided with an external thread, and the fresh air outlet pipe 702 is threadedly connected with the turbid air outlet 105.

[0117] In the embodiment of the present disclosure, the diameter of the fresh air outlet pipe 702 is relatively small, and the fresh air outlet pipe 702 is connected with the turbid air outlet 105 through thread rotation, so that the connection and disassembly of the fresh air outlet pipe 702 and the turbid air outlet 105 are facilitated, and no additional connecting piece is required, thereby improving the convenience of installation and disassembly.

[0118] Optionally, the other end of the second pipeline 92 is threadedly connected with the inner wall surface of the turbid air outlet 105.

[0119] Optionally, as shown, Figure 13 the connecting pipe 90 comprises a fresh air inlet pipe 701 in communication with the fresh air inlet 101, and the air conditioning device further comprises a connecting pipeline 703, one end of the connecting pipeline 703 being threadedly connected with the fresh air outlet pipe 702, and the other end of the connecting pipeline 703 being detachably connected with the fresh air inlet 101.

[0120] In the embodiment of the present disclosure, the diameter of the fresh air inlet pipe 701 is larger than the diameter of the fresh air outlet pipe 702, and therefore the air volume of the fresh air inlet pipe 701 is larger. Therefore, the fresh air inlet pipe 701 is connected with the fresh air inlet 101 through the connecting pipeline 703, which can improve the connection stability of the fresh air inlet pipe 701 and avoid the fresh air inlet pipe 701 from being deviated, bent or separated from the fresh air inlet 101 due to the influence of air flow.

[0121] Optionally, the other end of the connecting pipeline 703 is clamped with the fresh air inlet 101.

[0122] Optionally, the other end of the connecting pipe 703 is sleeved on the outside of the fresh air inlet 101. The outer wall of the fresh air inlet 101 is provided with a limiting post 704. The other end of the connecting pipe 703 is provided with a limiting groove 705. When the connecting pipe 703 is connected to the fresh air inlet 101, the limiting post 704 is located in the limiting groove 705, and the limiting post 704 abuts against the groove wall on one side of the limiting groove 705 to restrict the connecting pipe from rotating in a preset direction relative to the fresh air inlet 101.

[0123] Optionally, the opening area of ​​the limiting groove 705 is larger than the cross-sectional area of ​​the limiting post 704. In this way, when it is necessary to disassemble the fresh air inlet duct 701, the fresh air inlet duct 701 is rotated in the opposite direction to the preset direction, and the limiting groove 705 and the limiting post 704 no longer contact each other for limiting. This facilitates the disassembly of the fresh air inlet duct and the equipment body.

[0124] Optionally, there are multiple limiting slots 705, which are spaced apart along the circumference of the fresh air inlet duct 701. The number of limiting posts 704 is the same as the number of limiting slots 705 and corresponds one-to-one.

[0125] Optionally, the second pipe 92 of the fresh air intake duct 701 can be sleeved on the outside of the fresh air inlet 101. Here, since the second pipe 92 is made of flexible material, the second pipe 92 can be tightly attached to the outside of the duct wall of the fresh air inlet 101.

[0126] Optionally, such as Figures 10 to 12 As shown, the housing 10 defines a first airflow channel having a fresh air inlet 101, a first indoor outlet 102, and a first stale air inlet 103; a first fan 201 is located in the first airflow channel, the inlet of the first fan 201 is connected to the fresh air inlet 101 and / or the first stale air inlet 103, and the outlet of the first fan 201 is connected to the first indoor outlet 102; a first purification device 203 is disposed in the first airflow channel for purifying the airflow flowing into the fresh air inlet 101 and / or the first stale air inlet 103.

[0127] In the embodiments of the present disclosure, the first fan 201 can drive outdoor airflow to flow into the first airflow channel and then into the indoor space from the first indoor outlet 102 to provide fresh air for the indoor space. The first fan 201 can also drive indoor airflow to flow into the first airflow channel from the first turbid air inlet 103, and then flow into the indoor space from the first indoor outlet 102 after being purified by the first airflow channel. In this way, the air conditioning device can effectively distinguish the processing of fresh air and indoor turbid air by arranging the first airflow channel and the first purification device 203. Fresh air flows into the indoor space from the fresh air inlet 101, is purified by the first purification device 203 after flowing through the first airflow channel, and is then sent into the indoor space from the first indoor outlet 102. In this way, the fresh air can be provided to the indoor space, and impurities can be purified to ensure the air quality in the indoor space. Indoor turbid air flows into the indoor space from the first turbid air inlet 103, is purified by the first purification device 203, and is then sent back into the indoor space from the first indoor outlet 102. This separation processing manner significantly improves the air purification effect and ensures the continuous optimization of the indoor air quality.

[0128] The inlet of the first fan 201 is in communication with the fresh air inlet 101 and / or the first turbid air inlet 103, so that the device can flexibly switch between the fresh air mode and the internal circulation mode according to actual needs. In the fresh air mode, the device introduces outdoor fresh air; and in the internal circulation mode, the device purifies indoor air. This flexible air flow control manner can meet the air processing needs in different scenarios. By reasonably designing the air flow channel and the fan layout, the air conditioning device can effectively reduce energy consumption during operation. At the same time, the service life of the first purification device 203 is relatively long, which reduces the cost and resource waste of frequent replacement of filter screens, and is more energy-saving and environmentally friendly.

[0129] In addition, the fresh air inlet 101, the first turbid air inlet 103, and the first indoor outlet 102 of the shell 10 are integrated in the same air flow channel, which is compact in structure and facilitates installation and space layout. Moreover, the first purification device 203 and the fan are modularly designed, which facilitates disassembly and maintenance and prolongs the service life of the device.

[0130] Optionally, the first purification device 203 is a high-efficiency filter. For example, the first purification device 203 can be a HEPA filter, an activated carbon adsorption device, or the like.

[0131] In the embodiments of the present disclosure, the first purification device 203 is arranged in the first airflow channel and used to purify indoor turbid air flowing in from the first turbid air inlet 103 and / or fresh air flowing in from the fresh air inlet 101. By using multi-layer filtration or high-efficiency purification technology, particulate matter, odors, and harmful substances in the air can be effectively removed, and the cleanliness of indoor air is further improved.

[0132] Optionally, as shown in FIG. 1, the air conditioning device further comprises a second fan 202. Figure 15As shown, the air conditioning device further comprises an anti-backflow plate 30 and an internal purification plate 40. The anti-backflow plate 30 is movably arranged at the fresh air inlet 101 and is used to open or close the fresh air inlet 101. The internal purification plate 40 is movably arranged at the first turbid air inlet 103 and is used to open or close the first turbid air inlet 103. When the anti-backflow plate 30 opens the fresh air inlet 101 and the internal purification plate 40 closes the first turbid air inlet 103, the fresh air flowing into the fresh air inlet 101 is driven by the first fan 201 to flow through the first airflow channel and then flows out from the first indoor outlet 102 to the indoor space. When the anti-backflow plate 30 closes the fresh air inlet 101 and the internal purification plate 40 opens the first turbid air inlet 103, the indoor air is driven by the first fan 201 to flow into the first airflow channel from the first turbid air inlet 103 and then flows out from the first indoor outlet 102 to the indoor space after being purified by the first purification device 203.

[0133] In the embodiments of the present disclosure, the anti-backflow plate 30 is movably arranged at the fresh air inlet 101 and can open or close the fresh air inlet 101 as needed. When the outdoor air quality is poor (e.g., smog, dust, etc.), the anti-backflow plate 30 closes the fresh air inlet 101, effectively preventing outdoor pollutants from flowing back into the indoor space and ensuring the cleanliness of the indoor air. This design significantly enhances the environmental adaptability of the air conditioning device and is particularly suitable for use in severely polluted areas. The internal purification plate 40 is movably arranged at the first turbid air inlet 103 and can open or close the first turbid air inlet 103 as needed. When the anti-backflow plate 30 closes the fresh air inlet 101 and the internal purification plate 40 opens the first turbid air inlet 103, the device enters an internal circulation mode, and the first fan 201 drives the indoor air to flow into the first airflow channel from the first turbid air inlet 103 and then returns to the indoor space from the first indoor outlet 102 after being purified by the first purification device 203. This mode can efficiently purify the indoor air and is suitable for scenarios where the outdoor air quality is poor or the indoor air quality needs to be improved quickly. Through the coordinated work of the anti-backflow plate 30 and the internal purification plate 40, the air purification device can flexibly switch between the fresh air mode and the internal circulation mode according to actual needs. In the fresh air mode, the anti-backflow plate 30 opens the fresh air inlet 101, and the internal purification plate 40 closes the first turbid air inlet 103, and the device introduces outdoor fresh air. In the internal circulation mode, the anti-backflow plate 30 closes the fresh air inlet 101, and the internal purification plate 40 opens the first turbid air inlet 103, and the device purifies the indoor air in circulation. This flexible mode switching function can meet the air processing needs in different scenarios and improve user experience.

[0134] In addition, the design of the anti-backflow plate 30 and the internal purification plate 40 enables the air purification device to automatically select the optimal operation mode according to the indoor and outdoor air quality, avoiding unnecessary energy consumption. For example, when the outdoor air quality is good, the fresh air mode is preferred; when the outdoor air quality is poor, the internal circulation mode is automatically switched to, reducing the introduction of outdoor pollutants and reducing energy consumption. Moreover, the anti-backflow plate 30 and the internal purification plate 40 are designed to be movable, simple in structure and easy to realize automatic control. Through motor-driven or manual adjustment, the opening and closing state of the fresh air inlet 101 and the first turbid air inlet 103 can be quickly and accurately controlled, ensuring efficient operation of the device. By adding the anti-backflow plate 30 and the internal purification plate 40, the air conditioning equipment of the present application not only has the functions of anti-backflow and internal circulation purification, but also realizes flexible air flow mode switching and energy-efficient operation, significantly improving the practicality, environmental adaptability and user experience of the device.

[0135] Optionally, as shown in Figure 12 The shell 10 also defines a second air flow channel having a second turbid air inlet and a turbid air outlet 105, the turbid air outlet 105 being in communication with the outdoor, and the air conditioning equipment further comprises a second fan 202, the second fan 202 being located in the containing cavity, and the second fan 202 being communicated between the second turbid air inlet and the turbid air outlet 105; the second fan 202 can drive the indoor air flow to flow into the second air flow channel from the second turbid air inlet and then flow out from the turbid air outlet 105.

[0136] In the embodiments of the present disclosure, the second air flow channel is used to treat turbid air in the room, and the second fan 202 can drive the indoor turbid air to flow into the second air flow channel through the second turbid air inlet, and then be discharged to the outdoor from the turbid air outlet 105, so that indoor exhaust can be achieved. This independent air flow channel design avoids mixing of turbid air and fresh air, ensures the cleanliness of indoor air, and reduces pollution to the outdoor environment. Through the turbid air discharge function of the second air flow channel, the device can quickly discharge the polluted air in the room, avoiding the accumulation of pollutants in the room. By providing the second air flow channel and the second fan 202, the air conditioning equipment further increases the air treatment mode, the fresh air in the first air flow channel flows into the room to supplement fresh air, and the second air flow channel can discharge turbid air to the outdoor, thereby improving the air flow circulation between the indoor and outdoor, and quickly improving the indoor air quality. When the first air flow channel is in circulation, the air flow flowing into the room through the first turbid air inlet 103 flows into the room through the first purification device 203, and the air flow of the second air flow channel can be discharged to the outdoor, also improving the indoor air quality.

[0137] Optionally, the air conditioning device further comprises a second purification device 204 arranged in the second air flow channel and configured to purify the air flow flowing into the second turbid air inlet, and the second air blower 202 is capable of driving the air flow in the room to flow into the second air flow channel from the second turbid air inlet, and then to flow out of the turbid air outlet 105 after being purified by the second purification device 204.

[0138] In the embodiments of the present disclosure, the second air flow channel is used to treat the turbid air in the room, and the second air blower 202 is capable of driving the turbid air in the room to flow into the second air flow channel through the second turbid air inlet, and then to be discharged to the outside of the room from the turbid air outlet 105 after being purified by the second purification device 204, so that the air in the room can be discharged. The purification function of the second purification device 204 further improves the cleanliness of the air in the room, and provides a more healthy and comfortable air environment for the user. By arranging the second air flow channel, the second air blower 202 and the second purification device 204, the air conditioning device further increases the air treatment mode, the fresh air in the first air flow channel flows into the room to supplement the fresh air, and the turbid air in the second air flow channel is discharged to the outside of the room, so as to improve the air flow circulation between the inside and outside of the room, and quickly improve the air quality in the room.

[0139] Optionally, as shown in Figure 11 The shell 10 is further provided with a second indoor outlet 104, the second indoor outlet 104 is communicated with the second air flow channel, and the air conditioning device further comprises an air duct switching plate, the air duct switching plate is movably arranged in the second air flow channel, and is configured to adjust the outlet of the second air blower 202 to be communicated with the turbid air outlet 105 or the outlet of the second air blower 202 to be communicated with the second indoor outlet 104, so that the second air blower 202 drives the air flow flowing into the second turbid air inlet to flow to the outside of the room from the turbid air outlet 105 or to flow to the room through the second indoor outlet 104.

[0140] In the embodiments of the present disclosure, the air duct switching plate is movably arranged in the second air flow channel, and can adjust the communication state of the outlet of the second fan 202 with the turbid air outlet 105 or the second indoor outlet 104 according to actual needs. When the air duct switching plate communicates the outlet of the second fan 202 with the turbid air outlet 105, the air conditioning equipment enters the turbid air discharge mode, and the indoor turbid air is discharged to the outdoor after being purified; when the air duct switching plate communicates the outlet of the second fan 202 with the second indoor outlet 104, the air conditioning equipment enters the internal circulation mode, and the purified air flow is sent back to the indoor. This flexible mode switching function can meet the air treatment needs in different scenes, improve the practicality of the device, and improve the air treatment efficiency and energy utilization rate. Moreover, through the arrangement of the air duct switching plate, the communication of the outlet of the second fan 202 with the turbid air outlet 105 or the second indoor outlet 104 can be flexibly adjusted, the controllable adjustment of the air flow direction is realized, and the flexibility and diversity of air treatment are improved, and the efficiency of air treatment is improved. Through the design of the air duct switching plate, the second air flow channel can not only realize the discharge of turbid air, but also send the purified air flow back to the indoor. This dual-function integration enables the device to realize the dual effects of turbid air discharge and internal circulation purification in a single structure, saving space and cost. Moreover, the air duct switching plate enables the air conditioning equipment to automatically select the optimal operation mode according to the indoor and outdoor air quality. For example, when the outdoor air quality is poor, the air conditioning equipment can be switched to the internal circulation mode to avoid the introduction of outdoor pollutants; when the indoor air quality is poor, the air conditioning equipment can be switched to the turbid air discharge mode to quickly discharge the indoor turbid air. This intelligent operation mode not only improves the air treatment efficiency, but also reduces the energy consumption, and is more energy-saving and environmentally friendly.
