[0037] like Figure 1 Combination Figure 2 As shown, the utility model provides a ventilation device, including a main unit 1, a connecting piece 3 and an auxiliary unit 2; the main unit 1 is arranged corresponding to the second space, the auxiliary unit 2 is arranged corresponding to the first space, and the connecting piece 3 is buried in the wall between the second space and the first space; the main unit 1 includes a main shell mechanism and an air guide component, the air guide component is arranged in the main shell mechanism, the main shell mechanism is formed with a second air outlet 1021 and a second air inlet 1031, the second air inlet 1031 is connected to the second space, and the second air outlet 1021 is connected to one end of the connecting piece 3; the auxiliary unit 2 includes a sub-shell mechanism, the sub-shell mechanism is formed with a first air inlet 2031 and a first air outlet 2021, the other end of the connecting piece 3 is connected to the first air outlet 2021, and the first air inlet 2031 is connected to the first space.

[0038] Compared with the prior art, the ventilation device provided by the utility model has the following advantages:

[0039] The ventilation device provided by the utility model is arranged through a main unit 1 corresponding to the second space and an auxiliary unit 2 corresponding to the first space, and the second air outlet 1021 of the main unit 1 in the present application is connected with the second space, and the first air inlet 2031 of the auxiliary unit 2 is connected with the first space. An air guide component is provided in the main unit 1, and the gas in the first space can be sucked into the auxiliary unit 2 from the first air inlet 2031 through the air guide component, and enters the connecting piece 3 from the first air outlet 2021. Through the connecting piece 3 connected with the main unit 1 and the auxiliary unit 2, the gas in the first space can be circulated to the main unit 1.

[0040] Accordingly, air can enter through the second air inlet 1031 formed on the main unit 1, and the air in the first space can be introduced into the second space through the second air outlet 1021 formed on the main unit 1 and connected to the second space, thereby achieving gas circulation between the first space and the second space.

[0041] It can be understood that the first space and the second space in the present application refer to two indoor spaces where gas cannot circulate well. The first space in the present application mainly refers to the indoor living room. Correspondingly, the second space can be spaces such as bedrooms and cloakrooms.

[0042] Therefore, through the main unit 1 and auxiliary unit 2 provided in the present application, the construction method of penetrating beams can be avoided. It is only necessary to install the corresponding fresh air system in the living room. After purifying the living room space, the purpose of letting the fresh air in the living room enter the second space such as the bedroom can be achieved through the auxiliary unit 2 connected to the living room space and the main unit 1 connected to the auxiliary unit. This solves the existing construction method of penetrating beams, improves the safety of the building structure, and realizes the effective organization of the airflow in the user's home, thereby improving the user's respiratory health.

[0043] In some situations, such as during the night sleep period, a large amount of carbon dioxide and other gases will be produced when people sleep in the bedroom. Since the air flow in the bedroom is not good at night, the carbon dioxide will accumulate and make the air in the bedroom gradually turbid. At the same time, since the environment in the living room is larger and no one releases carbon dioxide, the auxiliary machine 2 is set in the living room and connected to the living room space, and the main machine 1 is set in the bedroom and connected to the bedroom space. In this way, during the night sleep stage, by turning on the main machine 1, the air in the living room can be sucked into the bedroom by using the air guide component, thereby diluting the carbon dioxide in the bedroom and improving the air quality in the bedroom and the sleep quality of the people.

[0044] In other situations, such as when someone is resting in the living room in summer and the air conditioner is turned on, the air flow in the living room and the bedroom is poor, so the cold air in the living room can hardly enter the bedroom. When someone in the bedroom also needs cold air, the air conditioner in the bedroom needs to be turned on, resulting in a huge waste of energy. Moreover, when the person in the living room enters the bedroom, the cold air in the living room will naturally dissipate within a certain period of time, which is also a waste of energy. Therefore, through the ventilation device provided by the present application, when the above-mentioned usage scenario occurs, the connection between the main unit 1 and the auxiliary unit 2 can be used to realize the transportation of cold air in the living room, thereby greatly improving the cooling area of ​​the air conditioner and reducing energy waste to a certain extent.

[0045] Furthermore, it is understandable that since the cooling of the air conditioner takes a certain amount of time, the ventilation device provided by the present application can also achieve pre-cooling in the bedroom. When people enter the bedroom from the living room, they can still be in a relatively comfortable environment. In this environment, turning on the air conditioner in the bedroom can also reduce the required power of the air conditioner in the bedroom and reduce energy loss.

[0046] It can be understood that since the auxiliary machine 2 in the present application is mainly arranged on the wall corresponding to the indoor living room, and the main machine 1 is mainly arranged on the wall corresponding to the bedroom, therefore, by arranging the air guide component in the main shell mechanism, it can ensure that the air in the first space is smoothly sucked in and released into the second space, avoiding the problem that the distance between the first space and the second space is too far and the length of the connecting piece 3 is too long, resulting in the air being unable to enter the second space well.

[0047] Alternatively, if Figure 1 Combination Figure 2As shown, the main shell mechanism in the present application includes a main frame 101, a first rear cover plate 103, a first front cover plate 102 and a first louver air outlet 104; the first rear cover plate 103 and the first front cover plate 102 are relatively arranged on both sides of the main frame 101, and are connected to the main frame 101 to form a main chamber, the second air outlet 1021 is formed on the first front cover plate 102, and the second air inlet 1031 is formed on the first rear cover plate 103; the first louver air outlet 104 is arranged to cover the first front cover plate 102 and is connected to the first front cover plate 102.

[0048] A main chamber for installing an air guide component can be formed by the main frame 101 and the first front cover 102 and the first rear cover 103 relatively arranged on both sides of the main frame 101. By forming a second air outlet 1021 on the first front cover 102 and a second air inlet 1031 on the first rear cover 103, the air guide component arranged in the main chamber can realize the function of allowing the gas in the first space to enter the main unit 1 through the second air inlet 1031 and flow out through the second air outlet 1021.

[0049] Correspondingly, since the main shell mechanism in the present application corresponds to the second space setting and the second air outlet 1021 needs to be connected to the second space, by covering the first louver air outlet 104 on the side of the first front cover plate 102 away from the air guide assembly, on the one hand, smooth exhaust can be achieved, and on the other hand, the first front cover plate 102 can also be shielded to improve the aesthetics of the overall device.

[0050] It should be additionally explained here that the host 1 in the present application is installed in the wall, and when the first space of the host 1 corresponds to the indoor bedroom, the host 1 is installed on the wall corresponding to the bedroom, so that by covering the first louver air outlet 104 on the first front cover plate 102, the internal first front cover plate 102 can be shielded, and the first louver air outlet 104 in the present application can be located on the same plane with the wall after installation, thereby ensuring the above-mentioned purpose of improving the overall aesthetics.

[0051] Alternatively, if Figure 1 Combination Figure 2 As shown, the main shell mechanism in the present application also includes a first sound insulation cotton 105, a second sound insulation cotton 106 and a main frame sound insulation cotton 107; the main frame sound insulation cotton 107 is arranged in affixed relation to the inner wall surface of the main frame body 101 along the circumference of the main frame body 101, the first sound insulation cotton 105 is arranged in affixed relation to the first front cover plate 102, and a first alignment opening 1051 is formed on the first sound insulation cotton 105 at a position corresponding to the second air outlet 1021; the second sound insulation cotton 106 is arranged in affixed relation to the first rear cover plate 103, and a second alignment opening 1061 is formed on the second sound insulation cotton 106 at a position corresponding to the second air inlet 1031.

[0052] By correspondingly attaching the first sound insulation cotton 105 on the first front cover 102, correspondingly attaching the second sound insulation cotton 106 on the first rear cover 103, and correspondingly attaching the main frame sound insulation cotton 107 on the inner wall of the main frame 101, a sound insulation cavity can be formed in the main cavity, thereby further isolating the noise generated by the air guide component during operation, further reducing the wind noise caused when the air is transferred from the auxiliary machine 2 to the main machine 1, and the wind noise generated when the air diffuses into the horizontal environment, thereby avoiding the problem of affecting the user's sleep and usage experience.

[0053] It can be understood that the first alignment opening 1051 formed by the first sound insulation cotton 105 and the second alignment opening 1061 formed by the second sound insulation cotton 106 can make the first sound insulation cotton 105 and the first front cover plate 102 fit better, as well as the second sound insulation cotton 106 and the first rear cover plate 103 fit better, thereby ensuring the sound insulation effect.

[0054] Alternatively, if Figure 2 As shown, the air guide assembly in the present application includes a fixing frame 109 and a fan 108. The fixing frame 109 is connected to the main frame 101 and is located between the main frame 101 and the first front cover 102. A positioning portion 1071 is formed on the main frame sound insulation cotton 107 corresponding to the position of the fan 108. The fan 108 is embedded in the positioning portion 1071, and the fan 108 is connected to the fixing frame 109.

[0055] The positioning portion 1071 formed by the main frame sound insulation cotton 107 can, on the one hand, realize the positioning and installation of the fan 108, and on the other hand, can reduce the vibration generated by the fan 108 when starting, and directly absorb the noise generated by the starting, thereby improving the sound insulation effect.

[0056] Correspondingly, by providing a fixing frame 109 connected to the main frame 101 , the limiting effect on the fan 108 can be further improved, thereby ensuring the stability of the operation of the fan 108 .

[0057] Alternatively, if Figure 2 As shown, the sub-shell mechanism in the present application includes a sub-frame 201, a second rear cover plate 202, a second front cover plate 203 and a second louver air outlet 204; the second rear cover plate 202 and the second front cover plate 203 are relatively arranged on both sides of the sub-frame 201, and are connected to the sub-frame 201 to form a sub-chamber, the first air outlet 2021 is formed on the second rear cover plate 202, and the first air inlet 2031 is formed on the second front cover plate 203; the second louver air outlet 204 is arranged to cover the second front cover plate 203, and is connected to the second front cover plate 203.

[0058] The sub-shell mechanism in the present application corresponds to the first space setting, that is, it is set in the wall corresponding to the living room. Accordingly, the second louver air outlet 204 is located in the same plane as the corresponding wall and covers the second front cover plate 203, thereby improving the appearance of the sub-shell mechanism.

[0059] Alternatively, if Figure 2 As shown, the sub-shell mechanism in the present application also includes a third sound insulation cotton 205, a fourth sound insulation cotton 206 and a sub-frame sound insulation cotton 207; the sub-frame sound insulation cotton 207 is arranged in affixed relation to the inner wall surface of the sub-frame 201 along the circumference of the sub-frame 201, the third sound insulation cotton 205 is arranged in affixed relation to the second front cover plate 203, and a third alignment opening 2051 is formed on the third sound insulation cotton 205 at a position corresponding to the first air inlet 2031; the fourth sound insulation cotton 206 is arranged in affixed relation to the second rear cover plate 202, and a fourth alignment opening 2061 is formed on the fourth sound insulation cotton 206 at a position corresponding to the first air outlet 2021.

[0060] By means of the third sound insulation cotton 205 corresponding to the second front cover 203, the fourth sound insulation cotton 206 corresponding to the second rear cover 202, and the sub-frame sound insulation cotton 207 corresponding to the inner wall surface of the sub-frame 201, the sub-frame mechanism can form a sound insulation space, so that when air enters the sub-shell mechanism, it can absorb the noise generated by the air flow, thereby ensuring the user experience.

[0061] It is understandable that since the main unit 1 is located in the bedroom and the auxiliary unit 2 is located in the living room, the first sound insulation cotton 105, the second sound insulation cotton 106 and the main frame sound insulation cotton 107 set in the main unit 1 and the third sound insulation cotton 205, the fourth sound insulation cotton 206 and the auxiliary frame sound insulation cotton 207 set in the auxiliary unit 2 can avoid the communication of sounds in the living room and the bedroom to a certain extent, that is, when the user is watching TV in the living room or watching TV in the bedroom, the sound will not be transmitted between the auxiliary unit 2 and the main unit 1, thereby ensuring the privacy of the space and improving the user experience.

[0062] Preferably, if Figure 1 Combination Figure 2 As shown, the number of the second air outlets 1021 in the present application is two, and they are relatively formed on both sides of the first front cover plate 102, and the second air inlet 1031 is located at the center of the first rear cover plate 103; the number of the first air inlet 2031 is two, and they are relatively formed on both sides of the second front cover plate 203, and the first air outlet 2021 is located at the center of the second rear cover plate 202.

[0063] It can be understood that by forming the second air outlet 1021 on both sides of the first front cover plate 102 relatively, and the second air inlet 1031 is located in the center of the first rear cover plate 103, when the sound enters the main chamber through the second air inlet 1031 of the first rear cover plate 103, continuous refraction can be generated, thereby reducing the transmission of sound under the sound absorption effect of the sound insulation cotton arranged in the main chamber.

[0064] Correspondingly, by forming the first air outlet 2021 at the center of the second rear cover 202, the two first air inlets 2031 are relatively formed on both sides of the second front cover 203, so that when the sound enters the sub-chamber from the first air inlet 2031, if it is to be transmitted toward the main unit 1, it also needs to be transmitted out from the first air outlet 2021 under continuous refraction. Under the action of the sound insulation cotton in the sub-chamber, the sound can be further absorbed, thereby avoiding the communication between the second space and the first space to a certain extent, thereby improving the user experience.

[0065] Alternatively, if Figure 3 Combination Figure 4 As shown, the ventilation device provided by the utility model also includes a distribution mechanism, which includes a distribution chassis 4 and a connecting pipe 5; the distribution chassis 4 is formed with a third air inlet 4011 and a third air outlet 4021, and the end of the connecting piece 3 away from the main unit 1 is connected to the third air outlet 4021, the third air inlet 4011 is connected to one end of the connecting pipe 5, and the other end of the connecting pipe 5 is connected to the auxiliary unit 2.

[0066] In some embodiments, due to different indoor layouts and user preferences or the need for cross-space layout, there will be a need to move the main unit. By setting up a distribution chassis 4, and connecting the distribution chassis 4 to the main unit 1 through a connecting piece 3, and connecting the auxiliary unit 2 to the distribution chassis 4 through a connecting pipe 5, the setting position of the main unit 1 can be made more flexible, and can be set at any position according to specific needs.

[0067] Correspondingly, the distribution box 4 in the present application is also composed of a distribution box front cover 402, a distribution box rear cover 403 and a distribution box frame 401, and the distribution box front cover 402 is affixed with a fifth sound insulation cotton 404, the distribution box rear cover 403 is affixed with a sixth sound insulation cotton 405, and the distribution box frame 401 is affixed with a distribution box sound insulation cotton 406 on the inner wall, thereby being able to ensure the sound absorption effect to a certain extent and improve the user experience.

[0068] It can be understood that by distributing the third air inlet 4011 formed by the chassis 4 and connecting the connecting pipe 5 with the third air inlet 4011, the introduction of air can be achieved, and by forming the third air outlet 4021, the connection with the connecting piece 3 can be achieved, thereby realizing the flow of air, guiding the air to the main unit 1 connected to the connecting piece 3, and then discharging the air through the main unit 1, thereby realizing the transfer flow of air.

[0069] Alternatively, if Figure 3 Combination Figure 4 As shown, the number of the third air inlets 4011 in the present application is multiple, and the multiple third air inlets 4011 are formed on the side wall of the distribution chassis 4 and are distributed at circumferential intervals around the distribution chassis 4; one end of the connecting pipe 5 is connected to any third air inlet 4011, and the other end is connected to the first air outlet 2021 of the auxiliary machine 2.

[0070] The distribution box in the present application is buried in the second space or in a wall corresponding to the second space. Correspondingly, the connecting pipe 5 in the present application is buried in the connecting wall between the first space and the second space. Therefore, the multiple third air inlets 4011 in the present application are formed on the side wall of the above-mentioned distribution box frame 401, so that they can better connect with the connecting pipes and ensure that the arrangement of the connecting pipes in the wall is smoother.

[0071] It can be understood that, through the multiple third air inlets 4011 formed on the distribution box frame 401, at least one connecting pipe 5 can be connected. When multiple auxiliary machines 2 are required to supply air to the main machine 1, the multiple connecting pipes 5 can be connected and multiple auxiliary machines 2 can be set accordingly to achieve the above-mentioned layout requirements.

[0072] Correspondingly, in this embodiment, the first air outlet 2021 is formed on the side wall of the sub-frame 201 , and a plurality of first air outlets 2021 are also formed to achieve smooth docking with the third air inlet 4011 mentioned above.

[0073] It should be noted that the connecting pipe 5 in the present application is a flat pipe, which can be better arranged in the wall without opening a deeper groove to ensure the strength of the wall. The third air inlet 4011 and the first air outlet 2021 in the present embodiment are both waist-shaped openings, so that they can match the end of the connecting pipe 5 to achieve smooth docking.

[0074] It needs to be further explained here that the connecting pipeline 5 in the present application can be composed of multiple straight pipe sections 501, and curved pipe sections can be further added. The curved pipe sections can realize the corners of the connecting pipe or the layout requirements of different heights.

[0075] In addition, the utility model also provides a fresh air system, including the above-mentioned ventilation device.

[0076] The fresh air system including the ventilation device provided in the present application, especially the ductless fresh air system, can better connect the air in the indoor space in series so that the air can be better circulated, thereby realizing the airflow organization and air quality control of the whole house, improving the user experience, and reducing the user's installation cost.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
