Description

Technical Field

[0001] The utility model relates to the field of bedding, in particular to a control box and a bed using the same. Background Art

[0002] The existing bed includes a bed frame, a control box and a mattress. An airbag is arranged in the mattress. The control box is used to control and adjust the air pressure in the airbag so that the airbag can realize functions such as adjusting the hardness of the mattress and massage. The air pressure control assembly includes an air pump, a main noise reduction box, a solenoid valve group and an exhaust valve which are arranged in series. Each valve body in the solenoid valve group is connected to a corresponding airbag through a bronchus. During use, the high-pressure gas generated by the air pump flows through the main noise reduction box and is then conveyed to the corresponding airbag through the valve body. The main noise reduction box reduces the noise of the high-pressure gas generated by the air pump, effectively reducing the noise of the control box during the inflation operation. The gas in the airbag is discharged to the outside through the corresponding valve body and the exhaust valve. Since the discharged air flow does not flow through the main noise reduction box, the control box will generate a large amount of noise during the deflation operation, which affects the user's sleep and the use experience. Content 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. By arranging an auxiliary noise reduction box on the bronchus, the air flow flowing through the bronchus is subjected to noise reduction treatment, effectively improving the noise reduction effect of the control box during the inflation operation and the deflation operation, and improving the use experience.

[0004] The utility model is realized in the following way: A control box includes a shell with an internal assembly cavity and an air pressure control assembly arranged in the assembly cavity. The air pressure control assembly includes a main air pipe connected to the air outlet of the air pump and a bronchus connected to the main air pipe through a solenoid valve group. An auxiliary noise reduction box is connected in series on the bronchus, and the air flow in the bronchus flows through the auxiliary noise reduction box and the noise is reduced. By arranging an auxiliary noise reduction box on the bronchus, the air flow for inflating and deflating the airbag will flow through the bronchus. By subjecting the air flow flowing through the bronchus to noise reduction treatment, the noise reduction effect of the control box during the inflation operation and the deflation operation is effectively improved, and the use experience is improved.

[0005] Preferably, an exhaust valve communicating with the outside space is arranged on the main air pipe, and the air flow in the bronchus flows through the auxiliary noise reduction box during the inflation and deflation operations of the target space. The exhaust valve realizes the connection between the main air pipe and the outside space by opening and closing, and further realizes the discharge of the gas in the airbag to the outside space through the bronchus with the auxiliary noise reduction box, the valve body, the main air pipe and the exhaust valve, effectively reducing the noise of the control box during the deflation operation.

[0006] Preferably, one end of the bronchus is connected to the solenoid valve group, the secondary noise reduction box is connected in series in the middle, and the other end is connected to the connecting socket arranged on the surface of the housing, so that the valve body communicates with the corresponding target space through the corresponding connecting socket. The solenoid valve group includes a plurality of valve bodies, and each valve body is connected to the corresponding target space through the corresponding bronchus, so that independent connection and disconnection control can be realized between each target space and the main air pipe by opening and closing the corresponding valve body. The secondary noise reduction box is arranged on the bronchus and can perform noise reduction processing on the air flow flowing through the bronchus, effectively reducing the influence of the noise generated by charging and discharging air on the user.

[0007] Preferably, there are two groups of the solenoid valve groups, including a support control group and a massage control group. Each valve body in the support control group is connected to the corresponding support airbag through a bronchus, and each valve body in the massage control group is connected to the corresponding massage airbag through a bronchus. By setting two groups of solenoid valve components to control different airbags, the support control group and the massage control group are respectively used to adjust the support airbag and the massage airbag, which not only effectively reduces the operating power of each air pump, but also ensures that the air pressure in each target space can be independently adjusted.

[0008] Preferably, the support airbag includes a back support airbag, a waist support airbag, a hip support airbag and a leg support airbag, and the secondary noise reduction box is arranged on the bronchi corresponding to the back support airbag and the waist support airbag. The secondary noise reduction box is arranged on the back support airbag and the waist support airbag, which not only reduces the influence on the user's sleep by performing noise reduction processing on the support airbags close to the user's head, but also reduces the occupied assembly cavity space by limiting the number of secondary noise reduction boxes, thereby reducing the volume of the control box and facilitating assembly and hiding.

[0009] Preferably, the massage airbag includes a back massage airbag, a waist massage airbag, a hip massage airbag and a leg massage airbag, and the secondary noise reduction box is arranged on the bronchi corresponding to the back massage airbag and the waist massage airbag. The secondary noise reduction box is arranged on the back massage airbag and the waist massage airbag, which not only reduces the influence on the user's sleep by performing noise reduction processing on the support airbags close to the user's head, but also reduces the occupied assembly cavity space by limiting the number of secondary noise reduction boxes, thereby reducing the volume of the control box and facilitating assembly and hiding.

[0010] Preferably, the secondary noise reduction box includes a buffer cavity and a first port and a second port respectively arranged on both sides of the buffer cavity, and the axes of the first port and the second port are perpendicular to each other. The buffer cavity is used to accumulate and buffer the air flow, so that the air flow decelerates and is temporarily stored in the buffer cavity, and the noise is reduced by reducing the air flow velocity. The first port and the second port are perpendicular to each other, and the air flow needs to turn in the buffer cavity when flowing between the first port and the second port, effectively reducing the air flow velocity and thus reducing the noise.

[0011] Preferably, a main noise reduction box is provided on the section of the main air pipe between the solenoid valve group and the air pump. The main noise reduction box is used to slow down the flow rate of the high-pressure air flow from the air pump, and thus play a role in uniformly reducing the noise of the air flow flowing to each target space on the main air pipe.

[0012] Preferably, a suspension is provided in the assembly cavity. The air pressure control assembly is suspended on the suspension through a bracket. An installation groove is provided on the suspension, and the auxiliary noise reduction box is embedded and fixed in the installation groove so that the auxiliary noise reduction box is fixedly connected to the air pressure control assembly through the suspension. The auxiliary noise reduction box is fixedly connected to the suspension, which is not only convenient for series connection with the bronchus, but also can use the suspension to eliminate the vibration of the auxiliary noise reduction box, thereby preventing noise generated by the vibration transmitted to the housing.

[0013] Preferably, a control board group is provided in the housing. The control board group includes a main control board and an auxiliary control board which are separately arranged. The main control board is arranged on the suspension, and a partition cavity for installing the auxiliary control board is provided on the surface of the housing to limit the transmission of the noise generated in the assembly cavity to the outside through the partition cavity. The main control board and the auxiliary control board are separately arranged, which not only protects the main control board, but also facilitates the connection of the auxiliary control board to the external pipeline, and also prevents the vibration generated by the operation of the internal components in the assembly cavity from being transmitted to the outside through the control board group, effectively reducing the noise.

[0014] Preferably, a cantilever is provided in the assembly cavity. The two 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, and the cantilever uses its own deformation to offset the vibration on the suspension, thereby reducing the noise generated by the vibration.

[0015] 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. The control box is arranged on the installation frame at the rear of the bed body, which is not only externally placed on the mattress, effectively reducing the vibration of the mattress, but also far away from the user's head, effectively reducing the impact of the operating noise on the user's sleep and improving the use experience.

[0016] The beneficial effects of the present utility model: An auxiliary noise reduction box is provided on the bronchus. The air flow for inflating and deflating the air bag will flow through the bronchus.

Specific embodiments

[0026] The following further describes the substantial features of the present invention in conjunction with the accompanying drawings of the specification and specific embodiments.

[0027] Embodiment 1:

[0028] This embodiment provides a control box.

[0029] As Figure 1 and 2 shown, the control box includes a housing 1 with an internal assembly cavity and an air pressure control component arranged in the assembly cavity. The air pressure control component includes a main air pipe 2 connected to the air outlet of the air pump 3 and a branch air pipe 5 connected to the main air pipe 2 through a solenoid valve group 4. The branch air pipe 5 is connected in series with an auxiliary noise reduction box 6, and the air flow in the branch air pipe 5 flows through the auxiliary noise reduction box 6 to reduce noise. By arranging the auxiliary noise reduction box 6 on the branch air pipe 5, the air flow for inflating and deflating the airbag will flow through the branch air pipe 5. By reducing the noise of the air flow flowing through the branch air pipe 5, the noise reduction effect of the control box 7 during the inflating and deflating operations can be effectively improved, and the user experience can be enhanced.

[0030] In this embodiment, an exhaust valve communicating with the external space is provided on the main air pipe 2, and the air flow in the bronchus 5 flows through the auxiliary noise reduction box 6 during the inflation and deflation operations of the target space. The exhaust valve opens and closes to control the connection and disconnection state between the main air pipe 2 and the external space, facilitating the discharge of excess gas in the main air pipe 2 to the external space.

[0031] In this embodiment, a main noise reduction box 13 is provided on the section of the main air pipe 2 between the solenoid valve group 4 and the air pump 3. The control box 7 performs deceleration and noise reduction processing on the air flow through the main noise reduction box 13 and the auxiliary noise reduction box 6. Specifically:

[0032] When the control box 7 inflates the target space, the high-pressure air flow generated by the operation of the air pump 3 will first undergo primary noise reduction through the main noise reduction box 13, then flow through the corresponding valve body and through the auxiliary noise reduction box 6 provided on the corresponding bronchus 5 for secondary noise reduction, and finally be delivered into the target space to inflate the target space.

[0033] When the control box 7 deflates the target space, the air in the target space flows through the auxiliary noise reduction box 6 provided on the corresponding bronchus 5 for noise reduction after the corresponding valve body is opened, and then is discharged to the external space through the exhaust valve provided on the main air pipe 2 to deflate the target space.

[0034] The auxiliary noise reduction box 6 can play a role in decelerating and reducing the noise of the air flow flowing through the corresponding bronchus 5 during both the inflation and deflation operations of the control box 7 on the target space. By reducing the air flow velocity, the generated noise is reduced, thereby reducing the impact on the user's sleep and improving the user experience.

[0035] In this embodiment, the noise will weaken as the propagation distance increases. The auxiliary noise reduction box 6 can be arranged in cooperation with some airbags close to the user's head, which not only ensures that the airbags close to the user's head have relatively low operating noise, thereby reducing the impact on the user's sleep, but also effectively reduces the number of settings of the auxiliary noise reduction box 6, reduces the volume of the control box 7, lowers the cost, and facilitates assembly and hiding.

[0036] In this embodiment, there are two groups of the solenoid valve group 4, including a support control group and a massage control group. Each valve body in the support control group is connected to the corresponding support airbag 19 through the bronchus 5, and each valve body in the massage control group is connected to the corresponding massage airbag 22 through the bronchus 5. The support control group is used to control the air pressure of the support airbag 19, and the massage control group is used to control the air pressure of the massage airbag 22. Since there are differences in the operation modes and operation parameters between the support airbag 19 and the massage airbag 22, by separately setting the support control group and the massage control group, it is convenient to independently control the support airbag 19 and the massage airbag 22 to ensure that the support airbag 19 and the massage airbag 22 can be accurately controlled.

[0037] In this embodiment, one end of the bronchus 5 is connected to the solenoid valve group 4, the middle part is connected in series with the auxiliary noise reduction box 6, and the other end is connected to the connection socket 8 arranged on the surface of the housing 1, so that the valve body is communicated with the corresponding target space through the corresponding connection socket 8. The bronchus 5 is used to connect the valve body and the target space, ensuring that the valve body realizes the switching of the connection and disconnection states among the main air pipe 2, the bronchus 5 and the corresponding target space through opening and closing, and thus can independently control each target space.

[0038] In this embodiment, the support airbag 19 includes a back support airbag, a waist support airbag, a hip support airbag and a leg support airbag. The auxiliary noise reduction box 6 is arranged on the bronchus 5 corresponding to the back support airbag and the waist support airbag. The massage airbag 22 includes a back massage airbag, a waist massage airbag, a hip massage airbag and a leg massage airbag. The auxiliary noise reduction box 6 is arranged on the bronchus 5 corresponding to the back massage airbag and the waist massage airbag. The back support airbag, the waist support airbag, the back massage airbag and the waist massage airbag are all arranged close to the user's head. By arranging the auxiliary noise reduction box 6 on the bronchus 5 corresponding to the above target space, the operation noise can be reduced. In addition, the auxiliary noise reduction box 6 can also be arranged on any bronchus 5 corresponding to the support airbag 19 and the massage airbag 22 according to needs, which should be regarded as the specific implementation manners of this embodiment.

[0039] In this embodiment, the auxiliary noise reduction box 6 includes a buffer cavity 9 and a first port 10 and a second port 11 (as Figure 6 shown) disposed on both sides of the buffer cavity 9. The axes of the first port 10 and the second port 11 are perpendicular to each other. The auxiliary noise reduction box 6 is in a cube shape, which is convenient for the auxiliary noise reduction boxes 6 to be closely attached to each other, effectively reducing the occupied space of the assembly cavity, and also convenient for assembling and fixing on the suspension 14, improving the convenience of disassembly and assembly.

[0040] In this embodiment, a suspension 14 is provided in the assembly cavity. The air pressure control component is suspended on the suspension 14 through a bracket 16. An installation groove 17 (as Figure 3 shown) is provided on the suspension 14. The auxiliary noise reduction box 6 is embedded and fixed in the installation groove 17, so that the auxiliary noise reduction box 6 and the air pressure control component are fixedly connected through the suspension 14. The cavity contour of the installation groove 17 matches the contour after the auxiliary noise reduction boxes 6 are closely stacked, which not only effectively reduces the occupied space of the assembly cavity, but also can clamp and position the closely stacked auxiliary noise reduction boxes 6 (as Figure 5 shown), preventing the auxiliary noise reduction box 6 from generating noise due to relative shaking and sliding.

[0041] Preferably, a control board group is provided in the housing 1. The control board group includes a main control board 18 and a sub-control board 12 (as Figure 4As shown in the figure, the main control board 18 is arranged on the suspension 14. A partition cavity for installing the secondary control board 12 is provided on the surface of the housing 1 to limit the transmission of noise generated in the assembly cavity to the outside through the partition cavity. The main control board 18 is arranged in the assembly cavity and fixedly connected to the suspension 14 for logic control. The secondary control board 12 is arranged in the partition cavity for connecting external interfaces. The main control board 18 and the secondary control board 12 are connected by a flexible cable, effectively preventing the vibration on the suspension 14 from being transmitted to the secondary control board 12 through the main control board 18, and further preventing the noise in the assembly cavity from being transmitted to the outside through the partition cavity.

[0042] Preferably, a cantilever 15 is arranged in the assembly cavity. Both ends of the cantilever 15 are fixedly connected to the cavity wall of the assembly cavity, and the middle part is fixedly connected to the suspension 14, so that the suspension 14 is suspended in the assembly cavity through the cantilever 15. The cantilever 15 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 14, thereby preventing the vibration on the suspension 14 from being transmitted to the housing 1, and further preventing the housing 1 from generating noise due to vibration.

[0043] Embodiment Two:

[0044] Compared with Embodiment One, this embodiment provides a bed.

[0045] As Figure 7 and 8 shown in the figure, the bed includes a bed body 20 and a mattress 21 arranged on the bed body 20. An upper massage airbag 22 and a lower support airbag 19 are arranged in the mattress 21. An installation frame 23 is provided at the bottom of the rear end of the bed body 20, and the control box 7 is arranged on the installation frame 23. The control box 7 is arranged on the installation frame 23 at the rear of the bed body 20, which is both externally placed outside the mattress 21, effectively reducing the vibration of the mattress 21, and is also far away from the user's head, effectively reducing the impact of the operating noise on the user's sleep and improving the use experience.

[0046] In this embodiment, the control box 7 is arranged on the installation frame 23 at the rear of the bed body 20, and the mattress 21 plays a role in isolating the user from the bed body 20, effectively eliminating the impact of the vibration of the control box 7 on the user's sleep.

[0047] In this embodiment, the mattress 21 is provided with a massage airbag 22 and a support airbag 19. The control box 7 independently adjusts the air pressure in the massage airbag 22 and the support airbag 19, so that the mattress 21 has the functions of adjustable softness and hardness and adjustable massage stimulation, effectively improving the use comfort and enhancing the use experience.

[0048] Other structures and effects of the control box 7 in this embodiment are the same as those in Embodiment One and will not be described in detail.
