The control box includes a housing with an internal assembly cavity and a pneumatic control component arranged in the assembly cavity. The pneumatic control component includes an air pump and a solenoid valve group connected in series through a main air pipe. The high-pressure air flow generated by the operation of the air pump is diverted and transported to each target space through the solenoid valve group. The operating air pump, solenoid valve group and the main air pipe for the flow of high-pressure air flow will all generate noise, and the noise is transmitted outward and affects the user's sleep, affecting the use experience. Summary of the Utility Model

[0003] In order to solve the deficiencies of the prior art, the utility model provides a control box and a bed using the same, and a noise reduction cavity filled with a noise reduction layer and wrapping the assembly cavity is provided, which effectively prevents the noise in the assembly cavity from being transmitted outward, reduces the influence on the user's sleep, and improves the use experience.

[0004] The utility model is realized in the following way: A control box includes a housing with an internal assembly cavity and a pneumatic control component arranged in the assembly cavity. A noise reduction cavity is arranged inside the housing, and the noise reduction cavity is filled with a noise reduction layer, and the noise reduction layer wraps the assembly cavity to limit the noise in the assembly cavity from passing through the housing and being transmitted outward. By arranging the noise reduction layer in the noise reduction cavity and wrapping the assembly cavity with the noise reduction layer, the noise generated in the assembly cavity can be effectively blocked from being transmitted outward, thereby reducing the influence on the user's sleep and improving the use experience. The noise reduction cavity provides a space for filling and positioning the noise reduction layer, and the noise reduction layer can effectively block the noise from being transmitted outward, thereby improving the noise reduction effect when the control box is operating.

[0005] Preferably, the housing includes a base provided with an assembly groove and a cover body covering the opening of the assembly groove. The noise reduction cavity includes a lower cavity and an upper cavity respectively arranged in the base and the cover body. When the cover body is covered in place, the noise reduction layer filled in the upper cavity and the lower cavity completely wraps the assembly cavity. The cover body covers the base, so that the cover body seals the assembly groove and forms the assembly cavity, which not only ensures the sealing of the assembly cavity, plays a role in fixing and protecting the pneumatic control component, but also can use the noise reduction layers arranged in the upper cavity and the lower cavity to isolate the noise generated in the assembly cavity, effectively reducing the noise transmitted outward when the control box is operating and improving the use experience. The noise reduction layers in the upper cavity and the lower cavity can completely wrap the assembly cavity, preventing the noise generated in the assembly cavity from spreading outward through the gaps between the noise reduction layers, and effectively improving the sound insulation effect.

[0006] Preferably, the cover body includes an outer cover and an inner cover which are vertically stacked and enclose an upper cavity. A first connecting column is provided on the bottom surface of the outer cover. The first connecting column passes through the corresponding noise reduction layer from top to bottom and is screwed and locked with the inner cover through a fastener. The outer cover and the inner cover are stacked and fixedly connected by abutting against the first connecting column. The fastener passes through the inner cover and is screwed and locked with the first connecting column, which not only ensures that an upper cavity with a thickness meeting the requirement for filling the noise reduction layer is formed between the outer cover and the inner cover, facilitating the filling and arrangement of the noise reduction layer, but also ensures the firm connection between the outer cover and the inner cover, plays a role in clamping and positioning the noise reduction layer, and prevents the noise reduction layer from affecting the sound insulation effect due to local deviation.

[0007] Preferably, the base includes an outer base and an inner base inserted into the outer base. An upwardly open inner cavity is provided on the outer base. A second connecting column extending upward is provided on the bottom wall of the inner cavity. When the inner base is inserted into the outer base from top to bottom, the second connecting column passes through the corresponding noise reduction layer from bottom to top and is screwed and locked with the bottom wall of the inner base through a fastener. The inner base is inserted into the inner cavity of the outer base and encloses a lower cavity for filling the noise reduction layer. The second connecting column not only plays a role in fixedly connecting the inner base and the outer base, but also ensures that the height of the lower cavity meets the need for filling the noise reduction layer, and also plays a role in limiting the noise reduction layer by passing through the noise reduction layer, preventing the noise reduction layer from affecting the sound insulation effect due to local deviation.

[0008] Preferably, the noise reduction layer includes a butyl rubber layer and a polyester fiber layer stacked and adhered together, which is not only convenient for processing and production, but also can effectively absorb and block noise, and effectively prevent the noise in the assembly cavity from being transmitted outward.

[0009] Preferably, a control board group is provided in the housing. The control board group includes a main control board and a sub-control board which are separately arranged. The noise reduction cavity includes a partition cavity for installing the sub-control board. An upwardly open partition groove is provided on the peripheral edge of the top surface of the base. The cover body covers the base and encloses the partition cavity with the partition groove. A noise reduction layer is provided in the partition cavity to limit the noise in the assembly cavity from being transmitted outward through the partition cavity. The main control board and the sub-control board are separately arranged, which not only plays a role in protecting the main control board, but also facilitates the connection of the sub-control board with external pipelines, and also prevents the vibration generated by the operation of the components inside the assembly cavity from being transmitted outward through the control board group, effectively reducing noise. The partition cavity, the upper cavity and the lower cavity cooperate and completely cover the surface of the assembly cavity to ensure that the noise generated in the assembly cavity will not be transmitted outward. The partition groove is covered by the cover body and encloses the partition cavity. The sub-control board is installed in the partition cavity, which plays a role in protecting and positioning the sub-control board. The noise reduction layer is filled in the partition cavity, playing a role in hindering the transmission of noise outward.

[0010] Preferably, a cantilever and a suspension for suspending a pneumatic control component are provided in the assembly cavity. Both ends of the cantilever are fixedly connected to the cavity wall of the assembly cavity, and the middle part is fixedly connected to the suspension, so that the suspension is suspended in the assembly cavity through the cantilever. The suspension is fixedly connected in the assembly cavity through the cantilever. The cantilever uses its own deformation to offset the vibration on the suspension, thereby reducing the noise generated by the vibration.

[0011] Preferably, the air pressure control component includes an air pump and a solenoid valve group suspended below the suspension by a shock-absorbing belt. The shock-absorbing belt can offset the vibration generated by the operation of the air pressure control component through its own deformation, and then reduce the noise by hindering the transmission of vibration.

[0012] Preferably, the air pressure control component includes a main air pipe connecting the air pump and the solenoid valve group in series, and a bronchial tube bridging between each valve body in the solenoid valve group and the corresponding target space. A main noise reduction box is provided on the section of the main air pipe between the air pump and the solenoid valve group, and a secondary noise reduction box is provided on the bronchial tube. By setting the main noise reduction box and the secondary noise reduction box, the high-pressure air flow in motion can be decelerated and the noise can be reduced. The main noise reduction box can reduce the noise of the high-pressure air flow output by the air pump, and the secondary noise reduction box can reduce the noise of the air flow flowing through the bronchial tube.

[0013] A bed using the control box includes a bed body and a mattress provided on the bed body. The mattress is provided with upper massage air bags and lower support air bags. An installation frame is provided at the bottom of the rear end of the bed body, and the control box is arranged on the installation frame.

[0014] The beneficial effects of the present utility model: A noise reduction layer is provided in the noise reduction cavity, and the noise reduction layer wraps the assembly cavity, effectively blocking the noise generated in the assembly cavity from being transmitted outward, thereby reducing the impact on the user's sleep and improving the use experience. The noise reduction cavity provides a space for filling and positioning for the noise reduction layer, and the noise reduction layer can effectively block the noise from being transmitted outward, thereby improving the noise reduction effect when the control box is operating.

Specific implementation mode

[0023] The following further describes the substantial features of the present invention in conjunction with the attached drawings of the specification and the specific implementation mode.

[0024] Embodiment 1:

[0025] This embodiment provides a control box.

[0026] As Figure 1 and 2 shown, the control box includes a housing 1 with an internal assembly cavity and a pneumatic control component arranged in the assembly cavity. A noise reduction cavity is provided in the housing 1, and a noise reduction layer 2 is filled in the noise reduction cavity. The noise reduction layer 2 wraps the assembly cavity to limit the noise in the assembly cavity from passing through the housing 1 and transmitting outward. By arranging the noise reduction layer 2 in the noise reduction cavity and wrapping the assembly cavity with the noise reduction layer 2, the noise generated in the assembly cavity can be effectively blocked from transmitting outward, thereby reducing the impact on the user's sleep and improving the use experience. The noise reduction cavity provides a filling and positioning space for the noise reduction layer 2, and the noise reduction layer 2 can effectively block the noise from transmitting outward, thereby improving the noise reduction effect of the control box during operation.

[0027] In this embodiment, the housing 1 includes a base 3 provided with an assembly groove and a cover body 4 covering the notch of the assembly groove (as Figure 5 shown). The noise reduction cavity includes an upper cavity provided in the cover body 4, a partition cavity 13 provided at the periphery of the top of the base 3, and a lower cavity provided in the base 3. When the cover body 4 is covered in place, the noise reduction layer 2 filled in the partition cavity 13, the upper cavity and the lower cavity completely wraps the assembly cavity, and the sound insulation effect is improved by increasing the coverage area of the noise reduction layer 2 on the surface of the assembly cavity, preventing the noise generated in the assembly cavity from passing through the housing 1 and transmitting outward.

[0028] In this embodiment, the cover body 4 includes an outer cover 5 and an inner cover 6 that are vertically stacked and enclose to form the upper cavity (as Figure 4As shown in the figure, a first connecting column 7 is provided on the bottom surface of the outer cover 5. The first connecting column 7 passes through the corresponding noise reduction layer 2 from top to bottom and is screwed and locked with the inner cover through a fastener. The outer cover 5 and the inner cover 6 are vertically stacked and enclosed to form an upper cavity. During assembly, the noise reduction layer 2 is laid on the top surface of the inner cover 6, the outer cover 5 is covered above the inner cover 6, the first connecting column 7 passes through the noise reduction layer 2 and abuts against the top surface of the inner cover 6, and the fastener passes through the inner cover 6 from bottom to top and is screwed and locked with the first connecting column 7, so that the outer cover 5 and the inner cover 6 are vertically stacked and fixedly connected and clamp the noise reduction layer 2 located in the upper cavity, ensuring that the noise reduction layer 2 is laid flat in the upper cavity, playing a role in isolating the noise transmitted from the assembly cavity to the upper cavity, and preventing the noise in the assembly cavity from being transmitted outward through the cover body 4. The first connecting columns 7 are multiple and are separately arranged to ensure that the thickness of each area in the upper cavity is consistent.

[0029] In this embodiment, the base 3 includes an outer seat 8 and an inner seat 9 inserted into the outer seat 8 (as Figure 3 shown in the figure). An upwardly open inner cavity is provided on the outer seat 8. A second connecting column 10 is formed by upward extension on the bottom wall of the inner cavity. When the inner seat 9 is inserted into the outer seat 8 from top to bottom, the second connecting column 10 passes through the corresponding noise reduction layer 2 from bottom to top and is screwed and locked with the bottom wall of the inner seat 9 through a fastener. The inner seat 9 is inserted into the inner cavity of the outer seat 8 and enclosed to form a lower cavity. During assembly, the noise reduction layer 2 is laid on the cavity wall of the inner cavity, the second connecting column 10 passes through the noise reduction layer 2 and is exposed, the inner seat 9 is inserted into the inner cavity of the outer seat 8 and abuts against the second connecting column 10, and the fastener passes through the inner seat 9 and is screwed and locked with the second connecting column 10, so that the inner seat 9 and the outer seat 8 are fixedly connected and clamp the noise reduction layer 2 located in the lower cavity, ensuring that the noise reduction layer 2 is laid flat in the lower cavity, playing a role in isolating the noise transmitted from the assembly cavity to the lower cavity, and preventing the noise in the assembly cavity from being transmitted outward through the periphery and bottom of the base 3. The second connecting columns 10 are multiple and are separately arranged to ensure that the thickness of each area at the bottom of the lower cavity is consistent.

[0030] In this embodiment, a downwardly open partition groove is provided on the peripheral edge of the top surface of the base 3. The cover body 4 is covered on the base 3 and encloses the partition cavity 13 with the partition groove. A noise reduction layer 2 is provided in the partition cavity 13 to limit the transmission of noise in the assembly cavity outward through the partition cavity 13. During assembly, the noise reduction layer 2 is filled in the partition groove, and the cover body 4 is covered on the base 3 and seals the partition groove to form a ring-shaped partition cavity 13 on the peripheral edge of the top of the base 3, playing a sound insulation effect at the joint of the cover body 4 and the base 3 and preventing the noise in the assembly cavity from being transmitted outward through the peripheral edge area of the top of the base 3.

[0031] In this embodiment, the noise reduction layer 2 includes a butyl rubber layer and a polyester fiber layer that are stacked and adhered. Each area of the noise reduction layer 2 has the same hierarchical structure and hierarchical thickness, so that each area has an equal sound insulation effect. The noise reduction layer 2 includes a butyl rubber layer and a polyester fiber layer that are stacked and adhered. The noise and vibration transmitted outward from the assembly cavity are absorbed and offset by the deformation of the noise reduction layer 2 itself, thereby reducing the noise during the operation of the control box and reducing the impact on the user's sleep.

[0032] In this embodiment, a control board group is provided in the housing 1. The control board group includes a main control board 11 and a sub-control board 12 that are separately arranged. The noise reduction cavity includes a partition cavity 13 for installing the sub-control board 12. In addition to filling the noise reduction layer 2, the partition cavity 13 is also used to install the sub-control board 12. The main control board 11 is arranged on the suspension 15, and the sub-control board 12 is installed in the partition cavity 13. The partition cavity 13 is isolated from the assembly cavity, effectively restricting the noise generated in the assembly cavity from being transmitted outward through the partition cavity 13. The main control board 11 is arranged in the assembly cavity and fixedly connected to the suspension 15 for logical control. The sub-control board 12 is arranged in the partition cavity 13 for connecting external interfaces. The main control board 11 and the sub-control board 12 are connected by a flexible cable, effectively preventing the vibration on the suspension 15 from being transmitted from the main control board 11 to the sub-control board 12, and further preventing the noise in the assembly cavity from being transmitted outward through the partition cavity 13.

[0033] In this embodiment, a cantilever 14 and a suspension 15 for suspending the air pressure control component are provided in the assembly cavity. Both ends of the cantilever 14 are fixedly connected to the cavity wall of the assembly cavity, and the middle part is fixedly connected to the suspension 15, so that the suspension 15 is suspended in the assembly cavity through the cantilever 14. The cantilever 14 is a long strip-shaped elastic steel bar, and the elastic steel bar can use its own deformation to offset the vibration of the suspension 15, thereby preventing the vibration on the suspension 15 from being transmitted to the housing 1, and further preventing the housing 1 from generating noise due to vibration.

[0034] In this embodiment, the air pressure control component includes an air pump 17 and a solenoid valve group 18 that are suspended below the suspension 15 through a shock-absorbing belt 16. The shock-absorbing belt 16 has elasticity, so that it can absorb and offset the vibration generated during the operation of the air pump 17 and the solenoid valve group 18 through telescopic deformation, thereby preventing the suspension 15 from generating noise due to receiving vibration, and effectively reducing the noise generated in the assembly cavity.

[0035] In this embodiment, the air pressure control assembly includes a main air pipe connecting a series of air pumps 17 and a solenoid valve group 18 in series, and bronchial tubes bridging between each valve body in the solenoid valve group 18 and the corresponding target space. A main noise reduction box 19 is provided on the section of the main air pipe between the air pump 17 and the solenoid valve group 18, and a secondary noise reduction box 20 is provided on the bronchial tubes. The main noise reduction box 19 and the secondary noise reduction box 20 are provided to decelerate and reduce the noise of the flowing high-pressure air flow. The main noise reduction box 19 can reduce the noise of the high-pressure air flow output by the air pump 17, and the secondary noise reduction box 20 can reduce the noise of the air flow flowing through the bronchial tubes.

[0036] The control box not only isolates the vibrations generated during the operation of the air pump 17 and the solenoid valve group 18 by setting the cantilever 14, suspension 15, and shock-absorbing belt 16, preventing the vibrations from generating noise due to transmission to the housing 1 and performing multi-stage shock absorption treatment on the vibrations generated during the operation of the air pressure control assembly, but also decelerates and reduces the noise of the high-pressure air flow by setting the main noise reduction box 19 and the secondary noise reduction box 20, and further isolates the noise in the assembly cavity by setting the noise reduction layer 2, performing multi-faceted noise reduction treatment on the noise generated during the operation of the control box, effectively reducing the impact on the user's sleep and enhancing the user experience.

[0040] In this embodiment, the control box 26 is provided on the installation frame 25 at the rear of the bed body 21. The mattress 22 plays a role in isolating the user from the bed body 21, effectively eliminating the impact of the vibration of the control box 26 on the user's sleep.

[0041] In this embodiment, the mattress 22 is provided with massage air bags 23 and support air bags 24. The control box 26 independently adjusts the air pressure in the massage air bags 23 and the support air bags 24, enabling the mattress 22 to have the functions of adjustable softness and hardness and adjustable massage stimulation, effectively improving the use comfort and enhancing the user experience.
