Description

Technical Field

[0001] The present application relates to the technical field of exhaust machines, and in particular to a silent and vibration-reducing exhaust machine unit. Background Art

[0002] The exhaust fan is one of the common devices used for ventilation. It is often installed in the bathroom to extract the gas inside the bathroom. After that, the gas is discharged to the outside to replace the new air, so that the exhaust fan can effectively improve the indoor air quality, adjust the indoor temperature, and remove harmful gases and odors.

[0003] The exhaust fan includes an outer shell, a motor and fan blades. The motor and the fan blades are installed inside the outer shell. The rotation of the motor drives the fan blades to rotate. The rotation of the blades generates centrifugal force, causing the air to diffuse outward to form an airflow. At the same time, due to the movement of the airflow, the air in the bathroom is affected by the negative pressure of the exhaust fan, is sucked into the exhaust fan, and then discharged to the outside through the exhaust port.

[0004] At present, the top surface of the outer shell is often installed on the top surface of the ceiling. When the motor drives the fan blades to rotate, vibration will be generated. The vibration is then transmitted to the ceiling through the outer shell, thereby affecting the residents upstairs. Summary of the invention

[0005] In order to reduce the transmission of the vibration of the exhaust fan to the ceiling, the present application provides a silent and vibration-reducing exhaust unit.

[0006] The present application provides a silent and vibration-reducing exhaust unit, which adopts the following technical solution: A silent and vibration-reducing exhaust unit, comprising: Shell: The shell has a storage cavity inside, and the storage cavity is a cavity that passes through the bottom; Exhaust fan: the exhaust fan is arranged inside the shell, the exhaust fan is located in the storage cavity, the exhaust fan comprises a shell and fan blades, the shell has an installation cavity inside, the fan blades are installed in the shell, and a distance is set between the outer wall of the shell and the inner wall of the shell; Connecting assembly: The connecting assembly includes a mounting plate, a connecting member and a connecting plate, wherein the mounting plate is mounted on the outer wall of the shell, one end of the connecting member is connected to the side of the mounting plate away from the shell, the connecting plate is arranged on the inner wall of the shell, and the end of the connecting member away from the mounting plate passes through the connecting plate and the side wall of the shell at the same time; Vibration damping sleeve: the vibration damping sleeve is arranged on the outer wall of the connecting member close to one end of the shell, the vibration damping sleeve passes through the connecting plate and the side wall of the shell at the same time, a first rubber pad is fixed to the outer wall of the vibration damping sleeve, and the first rubber pad is located between the outer wall of the connecting plate and the inner wall of the shell; Vibration reduction assembly: The vibration reduction assembly is arranged between the mounting plate and the connecting plate.

[0007] By adopting the above technical scheme, a spacing is set between the outer wall of the shell and the inner wall of the outer shell, thereby reducing the contact between the shell and the outer shell, and reducing the transmission of vibration generated by the rotation of the fan blades to the outer shell. Correspondingly, the vibration-damping sleeve passes through the connecting plate and the side wall of the outer shell at the same time. Under the action of the vibration-damping sleeve, the direct contact between the outer wall of the connecting piece and the connecting plate and the outer shell can be reduced. When the connecting piece is vibrated, under the action of the vibration-damping sleeve, the vibration-damping sleeve has high elasticity. The vibration-damping sleeve will deform when subjected to external force, and can return to its original shape after the external force is removed, so that the vibration-damping sleeve can absorb and release impact energy. The vibration-damping sleeve can consume energy during the deformation and recovery process, thereby reducing the transmission of vibration. Under the action of the first rubber pad, when the connecting plate is vibrated, the transmission of vibration of the connecting plate to the outer shell is reduced, so that when the fan blades vibrate during rotation, the transmission of vibration to the outer shell can be reduced, thereby reducing the transmission of vibration to the ceiling.

[0008] Preferably, a nut is sleeved on the outer wall of the connecting piece, one side of the nut is pressed against the outer wall of the shell, and a second rubber pad is fixed to the outer wall of the vibration damping sleeve, and the second rubber pad is located between the outer wall of the shell and the inner wall of the nut.

[0009] By adopting the above technical solution, under the action of the nut, the connection stability between the connecting plate and the outer shell can be improved, and the connection between the connecting plate and the outer shell can be strengthened. Under the action of the second rubber pad, when the nut is vibrated, the vibration of the nut is reduced and transmitted to the outer shell.

[0010] Preferably, the vibration reduction assembly includes a vibration reduction seat, and the vibration reduction seat is installed between the mounting plate and the connecting plate.

[0011] By adopting the above technical solution, under the action of the vibration-damping seat, the shell vibrates, thereby driving the mounting plate to vibrate. When the vibration of the mounting plate is transmitted to the vibration-damping seat, the vibration-damping seat is elastic, and the vibration-damping seat consumes energy in the process of deformation and recovery, thereby reducing the vibration transmitted to the connecting plate. Correspondingly, the vibration received by the connecting plate is consumed by the vibration-damping seat, which can reduce the vibration received by the connecting plate from being transmitted to the shell, thereby reducing the vibration transmitted to the ceiling.

[0012] Preferably, a storage groove is provided inside the vibration damping seat, and a sensor is arranged inside the vibration damping seat. The sensor is located in the storage groove. There are two sensors, and the two sensors are located at both ends of the storage groove.

[0013] By adopting the above technical solution, under the action of the vibration damping seat, the vibration in the shell can be slowed down from being transmitted to the outer shell, making it difficult for the user to observe the vibration in the shell through the outer shell. When the fan blades in the shell fail to rotate, the vibration will intensify, and it will be difficult for the user to observe the situation inside the shell through the outer shell, making it difficult to know the occurrence of the fault in the first time. Under the action of the two sensors, when vibration occurs, the vibration damping seat is compressed, and the horizontal distance between the two sensors will be shortened, or the two sensors will move up and down in an offset manner, so that the distance between the two sensors will increase. Therefore, the distance between the two sensors can reflect the vibration caused by the rotation of the fan blades in the shell.

[0014] Preferably, the middle portion of the mounting plate protrudes outward, and the connecting member is located at the protruding portion of the mounting plate.

[0015] By adopting the above technical solution, the middle part of the mounting plate protrudes outward, thereby reducing the contact between the mounting plate and the shell, thereby reducing the area of ​​the shell vibration transmitted to the mounting plate. At the same time, it can also reduce the direct contact vibration of the connecting part of the connecting piece, thereby reducing the vibration of the connecting piece.

[0016] Preferably, a middle portion of the connecting plate protrudes toward one side of the housing, and the protruding portion of the connecting plate abuts against a side wall of the first rubber pad.

[0017] By adopting the above technical solution, the protruding part of the connecting plate abuts against the side wall of the first rubber pad, thereby reducing the contact area between the connecting plate and the inner wall of the first rubber pad, thereby reducing the area of ​​vibration of the connecting plate transmitted to the first rubber pad. The first rubber pad then consumes the vibration and reduces the vibration transmitted to the outer shell.

[0018] Preferably, a base is provided on the bottom surface of the shell, and a light panel is installed on the bottom surface of the base.

[0019] By adopting the above technical solution, a light board is installed on the bottom surface of the base, so that the present application can provide lighting while solving the exhaust function, thereby improving the applicability of the exhaust machine. At the same time, the functions required by the bathroom are combined together to save installation space. Moreover, after the airflow enters from multiple air vents, it passes through the top of the light board into the installation cavity, and then is discharged from the exhaust port, thereby taking away the heat emitted by the light board, achieving the effect of heat dissipation of the light board, thereby increasing the service life of the light board.

[0020] Preferably, a speaker is installed on the bottom surface of the shell.

[0021] By adopting the above technical solution, a speaker is installed on the bottom surface of the shell, which adds the function of playing music and further improves the applicability of the exhaust fan.

[0022] Preferably, an outer wall of the base is provided with a vent hole, and the vent hole is communicated with the installation cavity.

[0023] By adopting the above technical solution, the vent hole is connected with the installation cavity, the vent hole connects the outside with the installation cavity, the external air flow can flow into the installation cavity through the vent hole, and then be discharged from the exhaust port, and at the same time, the sound of the speaker is transmitted through the vent hole.

[0024] Preferably, an exhaust assembly is provided on the outer wall of the shell, and the exhaust assembly is used to exhaust the gas sucked into the installation cavity.

[0025] By adopting the above technical solution, the gas sucked into the installation cavity can be discharged under the action of the exhaust component.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. A spacing is provided between the outer wall of the shell and the inner wall of the outer shell, thereby reducing the contact between the shell and the outer shell, and reducing the transmission of vibration generated by the rotation of the fan blades to the outer shell. Accordingly, the vibration-damping sleeve passes through the connecting plate and the side wall of the outer shell at the same time. Under the action of the vibration-damping sleeve, the direct contact between the outer wall of the connecting piece and the connecting plate and the outer shell can be reduced. When the connecting piece is vibrated, under the action of the vibration-damping sleeve, the vibration-damping sleeve has high elasticity. The vibration-damping sleeve will deform when subjected to external force, and can return to its original shape after the external force is removed, so that the vibration-damping sleeve can absorb and release impact energy. The vibration-damping sleeve can consume energy during deformation and recovery, thereby reducing the transmission of vibration. Under the action of the first rubber pad, when the connecting plate is vibrated, the transmission of vibration of the connecting plate to the outer shell is reduced, so that when the fan blades vibrate during rotation, the transmission of vibration to the outer shell can be reduced, thereby reducing the transmission of vibration to the ceiling.

[0027] 2. Under the action of the vibration damping seat, the vibration in the shell can be slowed down from being transmitted to the outer shell, making it difficult for the user to observe the vibration in the shell through the outer shell. When the fan blades in the shell fail to rotate, the vibration will intensify, and it is difficult for the user to observe the situation inside the shell through the outer shell, making it difficult to know the occurrence of the fault in the first time. Under the action of the two sensors, when vibration occurs, the vibration damping seat is compressed, and the horizontal distance between the two sensors will be shortened, or the two sensors will move up and down in an staggered manner, so that the distance between the two sensors will increase. Therefore, the distance between the two sensors can reflect the vibration caused by the rotation of the fan blades in the shell. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The embodiment of the present application discloses a silent and vibration-reducing exhaust unit.

[0037] Reference Figure 1 and Figure 2 A silent and vibration-reducing exhaust unit comprises a shell 1, wherein the shell 1 has a storage cavity 11 inside, the storage cavity 11 is a cavity penetrating from the bottom, an exhaust fan 2 is arranged inside the shell 1, the exhaust fan 2 is located in the storage cavity 11, the exhaust fan 2 comprises a shell 21 and a fan blade 22, the shell 21 has an installation cavity 23 inside, the installation cavity 23 is a cavity penetrating from the bottom, the fan blade 22 is installed in the shell 21, the fan blade 22 is located at the top of the installation cavity 23, a distance is arranged between the outer wall of the shell 21 and the inner wall of the shell 1, so as to reduce the contact between the shell 21 and the shell 1, reduce the vibration generated by the rotation of the fan blade 22 from being transmitted to the shell 1, and thus reduce the vibration from being transmitted to the ceiling, an exhaust port is arranged on the side wall of the shell 1, one end of the shell 21 extends to the side wall of the shell 1, an opening is arranged on the extended part of the shell 21, the opening is opposite to the exhaust port, and the gas can flow to the exhaust port through the opening for discharge.

[0038] Reference Figure 3 and Figure 4A connecting assembly 3 is provided between the outer wall of the shell 21 and the inner wall of the shell 1. The connecting assembly 3 includes a mounting plate 31, a connecting piece and a connecting plate 33. In the embodiment of the present application, the mounting plate 31 and the connecting plate 33 are circular plates. The mounting plate 31 is fixed to the outer wall of the shell 21. The middle part of the mounting plate 31 protrudes outward, thereby reducing the contact between the mounting plate 31 and the shell 21. In the embodiment of the present application, the connecting piece is a screw 32. One end of the screw 32 is fixed to the side of the mounting plate 31 away from the shell 21. The screw 32 is located at the protruding part of the mounting plate 31, and the connecting plate 33 is arranged on one side of the inner wall of the shell 1. Accordingly, the middle part of the connecting plate 33 protrudes toward one side of the shell 1, and the protruding part of the connecting plate 33 is located on the inner wall of the shell 1, thereby reducing the contact area with the inner wall of the shell 1. The screw 32 is away from one end of the mounting plate 31 and passes through the protruding part of the connecting plate 33 and the side wall of the shell 1. The outer wall of the screw 32 is sleeved with a nut 34, and the nut 34 is pressed against the outer wall of the shell 21, thereby fixing the shell 21 to the shell 1.

[0039] A vibration-damping sleeve 35 is provided at one end of the screw rod 32 close to the shell 1. The vibration-damping sleeve 35 passes through the connecting plate 33 and the side wall of the shell 1 at the same time. Under the action of the vibration-damping sleeve 35, the direct contact between the outer wall of the screw rod 32 and the connecting plate 33 and the shell 1 can be reduced. The vibration-damping sleeve 35 is a rubber sleeve. When the screw rod 32 is vibrated, under the action of the vibration-damping sleeve 35, the vibration-damping sleeve 35 has high elasticity. The vibration-damping sleeve 35 will be deformed when subjected to external force, and can return to its original shape after the external force is removed, so that the vibration-damping sleeve 35 can absorb and release impact energy. The vibration-damping sleeve 35 can consume energy during the deformation and recovery process, thereby reducing the transmission of vibration.

[0040] Correspondingly, the outer wall of the vibration-damping sleeve 35 is fixed with a first rubber pad 36 and a second rubber pad 37. The first rubber pad 36 is located between the outer wall of the connecting plate 33 and the inner wall of the outer shell 1, and the second rubber pad 37 is located between the outer wall of the outer shell 1 and the inner wall of the nut 34. Under the action of the first rubber pad 36, when the connecting plate 33 is vibrated, the vibration of the connecting plate 33 is reduced from being transmitted to the outer shell 1. Correspondingly, under the action of the second rubber pad 37, when the nut 34 is vibrated, the vibration of the nut 34 is reduced from being transmitted to the outer shell 1. Therefore, when the fan blade 22 vibrates during rotation, the vibration can be reduced from being transmitted to the outer shell 1, thereby reducing the vibration from being transmitted to the ceiling.

[0041] Reference Figure 4A vibration reduction assembly 4 is arranged between the mounting plate 31 and the connecting plate 33. The vibration reduction assembly 4 includes a first mounting seat 41, a second mounting seat 42 and a vibration reduction seat 43. A mounting groove is provided on the side of the mounting plate 31 close to the connecting plate 33. One end of the first mounting seat 41 is inserted into the mounting groove. The end of the first mounting seat 41 away from the mounting plate 31 has a storage cavity 11. The shape of the first mounting seat 41 is consistent with the shape of the second mounting seat 42. The mounting form between the second mounting seat 42 and the connecting plate 33 is consistent with the mounting form between the first mounting seat 41 and the mounting plate 31. The embodiment of the present application is consistent with the above-mentioned formula, and no detailed description is given therein. The cavity of the first mounting seat 41 corresponds to the cavity of the second mounting seat 42, and a storage space is formed between the first mounting seat 41 and the second mounting seat 42. The vibration damping seat 43 is located in the storage space, and one end of the vibration damping seat 43 is inserted into the cavity of the first mounting seat 41, and the other end of the vibration damping seat 43 is inserted into the cavity of the second mounting seat 42, so that the vibration damping seat 43 is clamped between the first mounting seat 41 and the second mounting seat 42, so that the vibration damping seat 43 is installed between the mounting plate 31 and the connecting plate 33.

[0042] In the embodiment of the present application, the vibration damping seat 43 is a rubber seat. Under the action of the vibration damping seat 43, the shell 21 vibrates, thereby driving the mounting plate 31 to vibrate. When the vibration of the mounting plate 31 is transmitted to the vibration damping seat 43, the vibration damping seat 43 is elastic. The vibration damping seat 43 consumes energy during deformation and recovery, thereby reducing the vibration transmitted to the connecting plate 33. Accordingly, the vibration received by the connecting plate 33 is consumed by the vibration damping seat 43, which can reduce the vibration received by the connecting plate 33 from being transmitted to the shell 1, thereby reducing the vibration transmitted to the ceiling.

[0043] Reference Figure 4 A storage groove 431 is provided inside the vibration-damping seat 43, and a sensor 5 is embedded inside the vibration-damping seat 43. The sensor 5 is located in the storage groove 431. There are two sensors 5, and the two sensors 5 are located at both ends of the storage groove 431. The output ends of the two sensors 5 are arranged relatively to each other, so that the two sensors 5 can sense the distance between each other, and then detect the vibration situation in the shell 21.

[0044] Under the action of the vibration damping seat 43, the vibration in the shell 21 can be slowed down and transmitted to the outer shell 1, making it difficult for the user to observe the vibration in the shell 21 through the outer shell 1. When the rotation of the fan blades 22 in the shell 21 fails, the vibration will intensify, and it is difficult for the user to observe the situation inside the shell 21 through the outer shell 1, making it difficult to know the occurrence of the fault in the first time. Under the action of the two sensors 5, one sensor 5 is located at the end of the vibration damping seat 43 close to the mounting plate 31, and the other sensor 5 is located at the end of the vibration damping seat 43 close to the connecting plate 33. When vibration occurs, the horizontal distance between the two sensors 5 will be shortened during the compression of the vibration damping seat 43, or the two sensors 5 will move up and down in an offset manner, so that the distance between the two sensors 5 will increase. Therefore, the distance between the two sensors 5 can reflect the vibration caused by the rotation of the fan blades 22 in the shell 21.

[0045] When the horizontal distance between the two sensors 5 is shortened by 5mm-8mm, or the vertical distance between the two sensors 5 is increased by 5mm-8mm, and the duration exceeds 3 seconds, the information will be fed back to the device receiving the signal connected to the user, prompting the user that the vibration generated by the rotation of the fan blades 22 is large, a little abnormal, and needs attention. When the horizontal distance between the two sensors 5 is shortened by more than 8mm, or the vertical distance between the two sensors 5 is increased by more than 8mm, and the duration exceeds 3 seconds, the information will be fed back to the device receiving the signal connected to the user, prompting the user that the vibration generated by the rotation of the fan blades 22 is serious and needs continuous attention or maintenance, thereby reducing the situation where it is difficult for users to detect abnormalities in the equipment.

[0046] Reference Figure 2 There are multiple vibration damping seats 43, and the multiple vibration damping seats 43 are distributed along the circumference of the mounting seat. Correspondingly, there are multiple connecting components 3, and the multiple connecting components 3 are distributed along the outer wall of the shell 21, thereby further improving the connection stability between the shell 21 and the outer shell 1 and reducing the detachment between the shell 21 and the outer shell 1.

[0047] The bottom surface of the outer shell 1 is fixedly connected to the base 12, and the outer wall of the base 12 is provided with ventilation holes. There are multiple ventilation holes, and the multiple ventilation holes are arranged around the outer wall of the base 12. The ventilation holes are connected to the installation cavity 23. The ventilation holes connect the outside with the installation cavity 23. The external air flow can flow into the installation cavity 23 through the ventilation holes and then be discharged from the exhaust port.

[0048] Reference Figure 3 and Figure 5A speaker 6 is installed on the bottom of the shell 21, and the sound of the speaker 6 is transmitted through multiple ventilation holes. A light board 7 is installed on the bottom of the base 12, and the light board 7 seals the bottom of the storage cavity 11. Therefore, when the present application realizes the ventilation function, it also has the functions of playing music and lighting, thereby improving the applicability of the exhaust fan. At the same time, the functions required by the bathroom are combined together to save installation space. Moreover, after the airflow enters from the multiple ventilation holes, it passes through the top of the light board 7 and enters the installation cavity 23, and then is discharged from the exhaust port, thereby taking away the heat emitted by the light board 7, achieving the effect of heat dissipation of the light board 7, thereby increasing the service life of the light board 7.

[0049] Reference Figure 6 An exhaust assembly 8 is installed on the outer wall of the shell 1. The exhaust assembly 8 includes an exhaust pipe 81, a sound absorbing layer 82 and a connecting cloth 83. The exhaust pipe 81 is aligned with the exhaust port. One end of the exhaust pipe 81 is inserted into the opening of the shell 21. The exhaust pipe 81 is fixed to the inner wall of the shell 21. In the embodiment of the present application, the sound absorbing layer 82 is a sound absorbing cotton layer. According to different scenarios, the sound absorbing layer 82 can also be a foam plastic layer or a glass fiber layer, so that the sound absorbing layer 82 finally absorbs the sound wave energy propagating through the cavity of the exhaust pipe 81, and converts the sound waves into tiny vibrations or heat energy, thereby weakening the propagation of sound and achieving the effect of noise reduction. The connecting cloth 83 is sewn to the inner wall of the sound absorbing layer 82, and the sound absorbing layer 82 is located between the exhaust pipe 81 and the connecting cloth 83, so as to wrap the sound absorbing layer 82 inside and reduce the situation of the sound absorbing layer 82 loosening and falling.

[0050] The inner wall of the connecting cloth 83 is provided with a circulation hole, which penetrates the sound absorbing layer 82. The external air flows into the installation cavity 23 through the vent hole, and then the air enters the cavity of the connecting cloth 83 from the exhaust port. Under the action of the circulation hole, the air flows through the cavity of the connecting cloth 83 and is discharged. The sound absorbing layer 82 can reduce the noise generated when the air flows through the connecting cloth 83. When the speaker 6 is in the on state, the influence of the noise during the discharge of the air flow on the speaker 6 can be reduced, so that the user can better hear the sound emitted by the speaker 6.

[0051] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
