[0033] The following is a further detailed description of the implementation of the present application in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but cannot be used to limit the scope of the present application.

[0034] The various specific technical features and embodiments described in the specific implementation methods can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in this application are no longer described separately. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. The application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] It should be noted that, in the present application, down refers to the direction toward the ground, and up refers to the direction opposite to down. The first direction, the second direction, and the third direction are in a three-dimensional vertical coordinate system perpendicular to each other, and the first side of the second direction and the second side of the second direction are two opposite directions.

[0036] See also Figures 1 to 4The embodiment of the present application provides a fresh air device 1000, including a shell 100, a protective shell 200 and a temperature detection component 300. The shell 100 is formed with a flow port 100a, and the shell 100 has an air flow channel 100b connected with the flow port 100a. The protective shell 200 is arranged in the air flow channel 100b. The protective shell 200 is formed with an air permeable port 200a and a storage cavity 200b. The air permeable port 200a connects the storage cavity 200b and the air flow channel 100b. At least a part of the temperature detection component 300 is located in the storage cavity 200b.

[0037] The temperature detection element 300 can be used to detect the temperature of the airflow. The protective shell 200 has the function of fixing and protecting the temperature detection element 300.

[0038] The circulation port 100a can be connected to the outside world, and the airflow can enter the housing 100 or be discharged from the housing 100 through the circulation port 100a. The vent 200a is connected to the storage chamber 200b and the airflow channel 100b. With this design, on the one hand, the airflow can enter the storage chamber 200b through the vent 200a and contact the temperature detection member 300, so that the temperature detection member 300 can detect the airflow temperature. On the other hand, the airflow will not be retained in the storage chamber 200b, so that the airflow can flow smoothly in the airflow channel 100b.

[0039] The embodiment of the present application provides a fresh air device 1000, and the temperature detection member 300 can detect the temperature of the airflow entering the housing 100. The airflow will not be retained in the process of passing through the storage cavity 200b, so that the airflow can flow smoothly. The protective shell 200 can keep the temperature detection member 300 separated from other components to prevent the temperature detection member 300 from touching the components and causing damage.

[0040] For example, see Figure 2 The protective shell 200 is formed with an inlet and outlet 200c communicating with the storage chamber 200b, and the temperature detection component 300 enters and exits the storage chamber 200b through the inlet and outlet 200c, which is convenient to operate and can improve assembly efficiency.

[0041] In one embodiment, the circulation port 100a may be a fresh air port, and the air flow channel 100b may be a fresh air channel.

[0042] Outdoor airflow is usually referred to as fresh air. Outdoor airflow enters the fresh air device 1000 through the fresh air port and flows along the fresh air channel. The temperature detection member 300 can be used to detect the temperature of the airflow entering the housing 100 of the fresh air device 1000. The air vent 200a is connected to the storage chamber 200b and the fresh air channel. With this design, the airflow can enter the storage chamber 200b through the air vent 200a and contact the temperature detection member 300, so that the temperature detection member 300 can detect the temperature of the airflow entering the fresh air device 1000.

[0043] In some embodiments, the thickness of the protective shell 200 is greater than or equal to 4 mm (millimeter), for example, 4.0 mm, 4.2 mm, 4.4 mm, 4.6 mm, 4.8 mm or 5.0 mm, etc. By setting a suitable size, the safety of the temperature detection element 300 is improved.

[0044] The fresh air device 1000 provided in the embodiment of the present application can be installed on the ceiling or the ceiling panel. The ceiling panel can separate the indoor space into the ceiling space and the living space. Users carry out their daily lives in the living space, and the ceiling space is not only used to beautify the interior decoration, but also to install other equipment. In one embodiment, the fresh air device 1000 is arranged in the ceiling space. In this way, the fresh air device 1000 is hidden in the ceiling space, avoiding the user from directly observing the entire fresh air device 1000, thereby improving the visual aesthetics. It can be understood that the indoor space includes but is not limited to balconies, bathrooms, kitchens, etc., and can be a large-sized house, a small-sized house, or other types of production or living environments.

[0045] When the fresh air device 1000 provided in the embodiment of the present application is installed on a ceiling or a suspended ceiling panel, the second direction may be consistent with the up and down direction.

[0046] In some embodiments, the vent 200a extends along different sides of the protective shell 200. Figure 2 and Figure 3 The protective shell 200 includes a first side surface 210 and a second side surface 220 that are different from each other. Figure 2 Taking the flow path of the airflow shown as an example, when the airflow flows to the protective shell 200, its flow direction is roughly 90 degrees, and the airflow can continue to flow through the first side 210, the storage cavity 200b and the second side 220 through the air vents 200a extending on different sides. In this way, on the basis that the temperature detection element 300 can detect the airflow temperature, the wind resistance at the protective shell 200 is reduced, and the smoothness of the airflow is improved.

[0047] In one embodiment, please refer to Figure 2 and Figure 3 The protective shell 200 is formed with a plurality of spaced vents 200a, so that the wind resistance can be further reduced and the smoothness of the air flow can be improved. In addition, the amount of air in contact with the temperature detection element 300 can be increased, and the accuracy of the temperature detection element 300 in detecting the air flow temperature can be improved.

[0048] For some examples, see Figure 2The fresh air device 1000 includes a carrier 400, the fresh air device 1000 includes a temperature measuring line 500 electrically connected to the temperature detection element 300, the carrier 400 includes a carrier 410 and a pressing piece 420, a portion of the temperature measuring line 500 is located on the surface of the carrier 410, and the pressing piece 420 abuts against a side of the temperature measuring line 500 away from the carrier 410. The carrier 410 has a supporting effect on the temperature measuring line 500. In this way, under the joint action of the carrier 410 and the pressing piece 420, the temperature measuring line 500 can be prevented from shifting, thereby enhancing the stability of the temperature measuring line 500.

[0049] In one embodiment, please refer to Figure 2 The inlet and outlet 200 c and the surface of the carrier 410 are substantially at the same level, so that the temperature measuring wire 500 can be placed on the surface of the carrier 410 after passing through the inlet and outlet 200 c, which facilitates the laying of the temperature measuring wire 500.

[0050] In one embodiment, please refer to Figure 2 The support member 400 is formed with an escape space 400 a, and the escape space 400 a provides a gripping space for the operator, which is convenient for adjusting and loading and unloading the temperature measuring line 500.

[0051] In some embodiments, a groove 410a is formed on the surface of the carrier 410, a portion of the temperature measuring line 500 is located in the groove 410a, and a portion of the pressing sheet 420 extends to the opening side of the groove 410a. For example, see Figure 2 The groove 410a extends along the third direction, and under the guidance of the groove 410a, the temperature measuring line 500 extends along the third direction. In this way, the temperature measuring line 500 can be laid in a relatively straight posture to avoid bending, winding, etc. of the temperature measuring line 500.

[0052] For some examples, see Figure 2 The carrier 400 includes two convex ribs 430 respectively located on two opposite groove walls of the groove 410a, and the two convex ribs 430 clamp the temperature measuring wire 500 in the groove 410a. For example, the two convex ribs 430 clamp the temperature measuring wire 500 in the middle of the groove 410a, so that the temperature measuring wire 500 is spaced from the two groove avoidance surfaces of the groove 410a, which can prevent the temperature measuring wire 500 from contacting and rubbing with the groove avoidance surfaces, causing the surface of the temperature measuring wire 500 to be worn.

[0053] In the related art, a take-in and put-out opening is formed on the shell, and the operator's hand can be inserted into the shell through the take-in and put-out opening, which may easily touch the temperature detection component and the temperature measuring line by mistake, posing a great safety risk.

[0054] For some examples, see Figure 1The flow port 100a is formed on the first side wall 110 of the housing 100 along the first direction, and the second side wall 120 of the housing 100 along the second direction is formed with a take-in / take-out port 100c, which is connected to the airflow channel 100b, and the projection of the take-in / take-out port 100c is spaced from the projection of the temperature detection element 300 by taking the plane perpendicular to the second direction as the projection plane. The operator's hand can reach into the housing 100 through the take-in / take-out port 100c to disassemble and assemble parts.

[0055] For example, see Figure 1 and Figure 2 The temperature detection component 300 and the access port 100c are respectively arranged on opposite sides along the third direction. In this way, compared with the safety risks existing in the related art, the temperature detection component 300 and the access port 100c in the embodiment of the present application are kept at a distance. When the operator's hand is inserted into the shell 100, it is impossible to touch the temperature detection component 300, thereby reducing the safety risk and improving the safety of the fresh air equipment 1000.

[0056] For some examples, see Figure 1 The fresh air device 1000 includes a filter 600 located in the air flow channel 100b, and the filter 600 includes a plurality of filter units 610. The plurality of filter units 610 enter the air flow channel 100b through the access opening 100c and are arranged in sequence along the third direction. The functions of the filter 600 include but are not limited to removing dust, microorganisms and / or harmful gases in the air.

[0057] Exemplarily, the filter 600 includes but is not limited to a primary filter, a medium filter and a high efficiency filter. The primary filter is mainly used to filter impurities larger than 5 μm (micrometers); the medium filter is mainly used to filter impurities between 1 μm and 5 μm; the high efficiency filter is mainly used to filter impurities between 0.3 μm and 1 mm. The filter 600 can be used alone or in combination of at least two different types of filters 600 to adapt to different usage scenarios.

[0058] In one embodiment, taking two filter monomers 610 as an example, the first filter monomer 610 is placed into the housing 100 through the access port 100c, and the filter monomer 610 is pushed along the third direction to move toward the side away from the access port 100c, and then the second filter monomer 610 is placed into the housing 100 through the access port 100c to achieve the parallel arrangement of the two filter monomers 610. In this way, on the one hand, the contact area between the filter 600 and the airflow is increased, and the filtering performance of the fresh air device 1000 is improved. On the other hand, the opening size of the access port 100c can be reduced to prevent the operator's hand from entering the housing 100 and accidentally touching the temperature detection component 300, and the design and manufacturing difficulty of the housing 100 can also be reduced.

[0059] For some examples, see Figure 2 , the protective shell 200 is arranged on the first side wall 110, the protective shell 200 and the circulation port 100a are spaced apart along the third direction, and the access port 100c is located where the circulation port 100a is located. In other words, the protective shell 200 and the first side wall 110 jointly define the storage cavity 200b. In this way, on the one hand, the additional parts required to fix the protective shell 200 can be reduced, and the production cost can be reduced. On the other hand, the interference between the protective shell 200 and other parts can be reduced, the safety of the temperature detection component 300 can be enhanced, and the layout of the fresh air equipment 1000 can be optimized.

[0060] For example, see Figure 1 , the filter 600 is arranged at the access opening 100c, and at least part of the filter 600 faces the circulation opening 100a. That is to say, the outdoor airflow enters the housing 100 through the circulation opening 100a and flows to the filter 600. After passing through the filter 600, at least part of the airflow flows to the protective shell 200, that is, flows to the temperature detection element 300. In this way, the dust and particles in the airflow are filtered out through the filter 600, which can improve the cleanliness of the airflow, keep the temperature detection element 300 clean, and extend the service life of the temperature detection element 300.

[0061] Furthermore, the temperature detection element 300 is spaced from the flow port 100a, thus extending the path of the outdoor airflow to the temperature detection element 300, so that the airflow contacts the temperature detection element 300 in a more uniform and stable state, effectively protecting the temperature detection element 300.

[0062] For some examples, see Figure 4 The fresh air device 1000 includes an inspection cover 700, which is connected to the housing 100 to selectively cover or open the access port 100c. For example, the fresh air device 1000 is installed on the ceiling, and the access port 100c is facing downward. The inspection cover 700 covers the access port 100c, which can prevent dust and / or water in the air from entering the heat exchange chamber, and can also prevent the filter 600 from loosening and falling through the access port 100c to cause safety risks. When the filter 600 needs to be replaced, the inspection cover 700 is moved to open the access port 100c, the original filter 600 is taken out, and a new filter 600 is put in, which is convenient to operate.

[0063] In some embodiments, the fresh air device 1000 includes a heat exchange core, which is located in the housing 100, a portion of the surface of the heat exchange core is a portion of the airflow channel 100b, the flow port 100a is formed on the first side wall 110 of the housing 100 along the first direction, the temperature detection member 300 extends along the second direction, and the temperature detection member 300 and the flow port 100a are spaced apart along the third direction. In this way, the temperature detection member 300 is always spaced apart from the flow port 100a to prevent the airflow carrying impurities and / or turbulence from directly contacting the temperature detection member 300, causing damage to the temperature detection member 300.

[0064] The heat exchange core is used to exchange heat between indoor and outdoor airflows, which can effectively improve heat exchange efficiency and reduce energy consumption. For example, the outdoor airflow with a higher temperature and the indoor airflow with a lower temperature exchange heat in the heat exchange core, and the indoor airflow can absorb the heat from the outdoor airflow, and send the comfortable outdoor airflow into the room, changing the temperature and / or humidity of the indoor environment and improving the user experience.

[0065] For example, see Figure 1 and Figure 2 , the temperature detection member 300 extends to the end of the first side of the side wall along the second direction. Taking the fresh air device 1000 set on the ceiling as an example, at this time, the opening sides of the inlet and outlet 200c and the groove 410a are both facing downward, and the operator works below the fresh air device 1000. In this way, it is convenient for the operator to load, unload and repair the temperature detection member 300 and the temperature measuring line 500.

[0066] In this embodiment, the first side of the second direction may coincide with the bottom.
