An airbag is arranged in the mattress, and the control box is used to control and adjust the air pressure in the airbag so as to realize functions such as adjusting the hardness and softness of the mattress and massaging. The airbags are multiple groups and are used to realize different functions, including support airbags and massage airbags. The control box is provided with a pneumatic control component corresponding to each type of airbag. The pneumatic control component includes an air pump and a solenoid valve group. During use, each pneumatic control component inflates and adjusts the corresponding airbag. If the power of the air pump is large, it will increase the volume of the control box and the operating noise. If the power of the air pump is small, it will affect the air pressure adjustment efficiency and the use experience. Content of the Utility Model

[0003] In order to solve the deficiencies of the existing technology, the utility model provides a control box and a bed using the same. A communication valve is arranged between the main air pipes of the pneumatic control components, so that the air pumps in each pneumatic control component can realize connection and disconnection switching through the communication valve. It can not only improve the inflation efficiency through combined use, but also reduce the volume of the control box by limiting the power of the air pump, reduce the operating noise and improve 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. The pneumatic control component includes a main air pipe, an air pump and a solenoid valve group arranged on the main air pipe. The pneumatic control components are two groups, and the main air pipes of the pneumatic control components are connected through a communication valve. The pneumatic control component realizes switching between a combined operation state of mutual connection and an independent operation state of mutual isolation by opening and closing the communication valve. A communication valve is arranged between the main air pipes of the pneumatic control components, so that the air pumps in each pneumatic control component can realize switching between the combined operation state and the independent operation state by opening and closing the communication valve. It can not only improve the inflation efficiency through combined use, but also reduce the volume of the control box by limiting the power of the air pump, reduce the operating noise and improve the use experience.

[0005] Preferably, the solenoid valve group includes several valve bodies connected in series on the main air pipe in sequence. The valve body is communicated with the corresponding target space through a bronchus, so that the air pressure in each target space can be adjusted. The solenoid valve group includes multiple valve bodies independently communicated with the corresponding target space, so that the air pump can independently inflate each target space through the solenoid valve group. The air pumps in different pneumatic control components can realize combined operation through the opened communication valve, effectively improving the inflation efficiency for a single or part of the target spaces and improving the use experience.

[0006] Preferably, the first end of the main air pipe is connected to an air pump, and the second end passes through the solenoid valve group and is connected to the communication valve, so that the main air pipes are connected through the communication valve. The main air pipe not only plays the role of connecting the air pump and each valve body in the solenoid valve group, enabling the high-pressure air flow generated by the air pump to be delivered to each valve body, and then inflating the target space connected to each valve body, but also plays the role of connecting to the communication valve, for receiving the high-pressure air flow generated by other pneumatic control components, and improving the inflation efficiency through the coordinated operation of multiple air pumps.

[0007] Preferably, a buffer air box is provided on the section of the main air pipe between the air pump and the solenoid valve group. The high-pressure air flow generated by the air pump flows through the buffer air box and the noise is reduced. The buffer air box can receive the high-pressure air flow generated by the air pump and deliver it to the solenoid valve group, playing the role of slowing down the air flow velocity and reducing the noise.

[0008] Preferably, an exhaust valve is provided on the main air pipe, and the main air pipe is communicated with the external space through the exhaust valve. When the exhaust valve is opened and the main air pipe is communicated with the external space, the gas in the target space can sequentially pass through the corresponding valve body, the main air pipe and the exhaust valve and be discharged to the external space, performing a deflation operation on the target space.

[0009] Preferably, there is one exhaust valve and it is provided on any one of the main air pipes, so that the pneumatic control components share the exhaust valve when the communication valve is opened. Since the communication valve can connect the main air pipes, multiple groups of pneumatic control components can share one exhaust valve, enabling the gas in the target space to sequentially pass through the corresponding valve body, the corresponding main air pipe, the communication valve and the main air pipe with the exhaust valve and then be discharged to the outside. Simplifying the structure by sharing the exhaust valve facilitates assembly, use and maintenance.

[0010] Preferably, a control board group is provided inside the housing. The control board group includes a main control board and a sub-control board which are separately arranged. An isolation cavity isolated from the assembly cavity is provided inside the housing. The main control board is arranged on a suspension in the installation cavity, and the sub-control board is installed in the isolation cavity to limit the noise generated in the assembly cavity from being transmitted outward through the isolation cavity. The main control board and the sub-control board are separated from each other, which not only protects the main control board, but also facilitates the connection of the sub-control board to external pipelines, and 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 the noise.

[0011] Preferably, the pneumatic control component is installed in the assembly cavity through a suspension with a cantilever. 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 pneumatic control component is suspended in the assembly cavity. The suspension is fixedly connected to 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.

[0012] A bed using the control box, comprising a bed body and a mattress arranged 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 externally placed outside the mattress, effectively reducing the vibration of the mattress, and is also far from the user's head, effectively reducing the impact of operating noise on the user's sleep and improving the use experience.

[0013] Preferably, the air pressure control assembly is connected to each support air bag through a solenoid valve group, so that the air pressure in each support air bag can be independently adjusted. The air pressure control assembly is connected to each massage air bag through a solenoid valve group, so that the air pressure in each massage air bag can be independently adjusted. The target spaces are the support air bags and the massage air bags, which respectively play the roles of adjusting the support degree and applying massage stimulation. By setting two groups of air pressure control assemblies to respectively control the support air bags and the massage air bags, it is ensured that the support air bags and the massage air bags can be independently controlled.

[0014] Preferably, when the connection valve is opened, the two groups of air pressure control assemblies can cooperate to adjust the air pressure in any support air bag and / or massage air bag. The air pumps in the two groups of air pressure control assemblies can quickly adjust the air pressure in the support air bag and / or massage air bag when the connection valve is opened, effectively improving the inflation efficiency and improving the use experience by shortening the inflation time.

[0015] The beneficial effects of the present utility model: A connection valve is arranged between the main air pipes of the air pressure control assembly, so that the air pumps in each air pressure control assembly can switch between the cooperative operation state and the independent operation state by opening and closing the connection valve. It can not only improve the inflation efficiency through cooperative use, but also reduce the volume of the control box by restricting the power of the air pump, reduce the operating noise, and improve the use experience.

Specific embodiments

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

[0024] Embodiment 1:

[0025] This embodiment provides a control box.

[0026] As Figure 1 and 2 shown, a control box includes a housing 1 with an internal assembly cavity and an air pressure control component 2 arranged in the assembly cavity. The air pressure control component 2 includes a main air pipe 3 and an air pump 4 and a solenoid valve group arranged on the main air pipe 3. There are two groups of the air pressure control components 2, and the main air pipes 3 of the air pressure control components 2 are connected by a connection valve 5. The air pressure control component 2 realizes the switching between the coordinated operation state of being interconnected and the independent operation state of being isolated by opening and closing the connection valve 5. The connection valve 5 is arranged between the main air pipes 3 of the air pressure control components 2, so that the air pumps 4 in each air pressure control component 2 can realize the switching between the coordinated operation state and the independent operation state by opening and closing the connection valve 5, which can not only improve the inflation efficiency by using in cooperation, but also reduce the volume of the control box, lower the operating noise and improve the use experience by limiting the power of the air pump 4.

[0027] In this embodiment, the target space includes a support airbag 18 and a massage airbag 19, and there are two groups of the air pressure control components 2 which are respectively used to control the air pressure of each bladder in the support airbag 18 and the massage airbag 19. During installation, the solenoid valve group in one group of the air pressure control components 2 is connected to each independently arranged bladder in the support airbag 18 through a series of valve bodies 6, and the solenoid valve group in the other group of the air pressure control components 2 is connected to each independently arranged bladder in the massage airbag 19 through a series of valve bodies 6, and the main air pipes 3 of the two groups of the air pressure control components 2 are connected by an openable and closable connection valve, so that the connection and disconnection between the main air pipes 3 can be controlled. In addition, an exhaust valve 9 communicating with the outside space is arranged on any main air pipe 3, so that each bladder can be connected to the exhaust valve 9 through the main air pipe 3 for deflation operation of the bladder; an air pump 4 is arranged on each main air pipe 3, and the high-pressure air flow generated by the air pump 4 is transported to each target space through the main air pipe 3 for inflation operation of each bladder.

[0028] During use, the air pressure control component 2 realizes switching between a cooperating operating state of being interconnected and an independent operating state of being isolated through the opening and closing of the communication valve 5:

[0029] During inflation, when the communication valve 5 is closed, the main air pipes 3 are not interconnected with each other, and the air pumps 4 in each air pressure control component 2 can independently inflate the connected bladder through the corresponding main air pipe 3 and the valve body 6. The inflation speed is matched and associated with the power of the air pump 4 in the air pressure control component 2; when the communication valve 5 is opened, the main air pipes 3 are interconnected with each other, and the air pumps 4 in the two air pressure control components 2 operate simultaneously. The high-pressure air flow generated is transported to the corresponding valve body 6 in the target space through the interconnected main air pipes 3, and the target space is inflated by the coordinated operation of the two air pumps 4, effectively improving the inflation efficiency, shortening the inflation duration, and thus reducing the impact on the user's sleep.

[0030] During deflation, if the target space to be deflated and the exhaust valve 9 are on the same main air pipe 3, the exhaust valve 9 and the valve body 6 corresponding to the target space to be deflated are opened to allow the air in the target space to be discharged; if the target space to be deflated and the exhaust valve 9 are on different main air pipes 3, the exhaust valve 9, the communication valve 5, and the valve body 6 corresponding to the target space to be deflated are opened to allow the air in the target space to be discharged.

[0031] In this embodiment, the solenoid valve group includes a number of valve bodies 6 connected in series on the main air pipe 3 in sequence. The valve body 6 is connected to the corresponding target space through the branch air pipe 7 to enable the air pressure in each target space to be adjustable. By providing multiple valve bodies 6, it is convenient to independently control multiple independently arranged bladders, effectively improving the control accuracy and thus enhancing the user experience.

[0032] In this embodiment, the first end of the main air pipe 3 is connected to the air pump 4, and the second end passes through the solenoid valve group and is connected to the communication valve 5 so that the main air pipes 3 are connected through the communication valve 5. The solenoid valve group includes a number of valve bodies 6 connected in series in the middle section of the main air pipe 3, so that the high-pressure air flow generated by the air pump 4 can be transported to each valve body 6 along the way, and can also be transported to other main air pipes 3 through the communication valve 5 when the usage requirements of the corresponding valve body 6 are met, improving the inflation efficiency by coordinating the use of the air pump 4.

[0033] In this embodiment, a buffer air box 8 is provided on the section of the main air pipe 3 between the air pump 4 and the solenoid valve group (as Figure 3 shown), and the high-pressure air flow generated by the air pump 4 flows through the buffer air box 8 and the noise is reduced. The high-pressure air flow output from the air pump 4 all needs to pass through the buffer air box 8, effectively reducing the noise generated by the flow of the high-pressure air flow, and thus reducing the impact on the user's sleep.

[0034] In this embodiment, an exhaust valve 9 is provided on the main air pipe 3, and the main air pipe 3 is communicated with the external space through the exhaust valve 9. Specifically, there is one exhaust valve 9 and it is provided on any one of the main air pipes 3 so that the pneumatic control assembly 2 shares the exhaust valve 9 when the connection valve 5 is opened. By providing the connection valve 5, it is convenient to connect the main air pipes 3, and thus it is convenient to share the exhaust valve 9, effectively simplifying the pipeline structure and reducing the equipment cost by reducing the number of components. The exhaust valve 9 is preferably provided on the main air pipe 3 where the exhaust operation is frequent, so that the main air pipe 3 can be independently exhausted when the connection valve 5 is closed, and the exhaust efficiency is improved by shortening the distance of the air flow exhaust path.

[0035] In this embodiment, a control board group is provided in the housing 1. The control board group includes a main control board 10 and a sub-control board 11 which are separately arranged. An isolation cavity isolated from the assembly cavity is provided in the housing 1. The main control board 10 is arranged on a suspension 13 in the installation cavity, and the sub-control board 11 is installed in the isolation cavity to limit the noise generated in the assembly cavity from being transmitted outward through the isolation cavity. The main control board 10 is arranged in the assembly cavity and fixedly connected to the suspension 13 for logical control, and the sub-control board 11 is arranged in the isolation cavity for connecting external interfaces. The main control board 10 and the sub-control board 11 are connected by a flexible cable, effectively preventing the vibration on the suspension 13 from being transmitted from the main control board 10 to the sub-control board 11, and further preventing the noise in the assembly cavity from being transmitted outward through the isolation cavity.

[0036] In this embodiment, a cantilever 12 (as Figure 4 shown) is provided in the assembly cavity. Both ends of the cantilever 12 are fixedly connected to the cavity wall of the assembly cavity, and the middle part is fixedly connected to the suspension 13, so that the suspension 13 is suspended in the assembly cavity through the cantilever 12. The cantilever 12 is a long strip-shaped elastic steel strip, and the elastic steel strip can use its own deformation to offset the vibration of the suspension 13, thereby preventing the vibration on the suspension 13 from being transmitted to the housing 1, and further preventing the housing 1 from generating noise due to vibration.

An installation frame 16 is provided at the bottom of the rear end of the bed body 14, and the control box 17 is arranged on the installation frame 16. The control box 17 is arranged on the installation frame 16 at the rear of the bed body 14, which is both externally located with respect to the mattress 15, effectively reducing the vibration of the mattress 15, and is also far from the user's head, effectively reducing the influence of the operating noise on the user's sleep and improving the use experience.

[0040] In this embodiment, massage air bags 19 and support air bags 18 are provided in the mattress 15, and the control box 17 independently adjusts the air pressures in the massage air bags 19 and the support air bags 18, so that the mattress 15 has the functions of adjustable hardness and adjustable massage stimulation, effectively improving the use comfort and enhancing the use experience. Specifically, a set of air pressure control components 2 are connected to each support air bag 18 through a solenoid valve group, so that the air pressure in each support air bag 18 can be independently adjusted. Another set of air pressure control components 2 are connected to each massage air bag 19 through a solenoid valve group, so that the air pressure in each massage air bag 19 can be independently adjusted. When the communication valve 5 is opened, the two sets of air pressure control components 2 can cooperatively adjust the air pressure in any support air bag 18 and / or massage air bag 19, and the two air pumps 4 are used in cooperation to improve the efficiency when inflating a single or a small number of air bags.
