Description

Air pressure control system and mattress using the same Technical Field

[0001] The present invention relates to the field of sleeping, and in particular to an air pressure control system and a mattress using the same. Background Art

[0002] Existing smart mattresses provide users with more comfortable pre-sleep relaxation and sleep quality improvement services by integrating sensors, control boxes and functional parts, thereby realizing intelligent control of the mattress and providing a more comfortable sleeping environment. The mattress is provided with a functional module, and the control box is provided with an air pressure regulating module and a control module. The control module controls the operation of the air pressure regulating module and enables the functional module to produce corresponding functions. The functional module includes air springs for performing various functions, including support springs for adjusting the softness and hardness of the mattress and massage springs for enhancing massage stimulation. The air pressure regulating module includes an air pump and an air path structure connected between the air pump and the air spring. There are two existing air path structures, but both have defects:

[0003] Structure 1: The number of air pumps corresponds to the number of air springs. Each air spring can be configured with an air pump with corresponding parameters according to its own requirements to meet the differentiated needs of each air spring. Due to the large number of air pumps, the power and volume of each air pump are limited, resulting in low inflation efficiency for air springs with large air volume requirements, affecting the user experience.

[0004] Structure 2: An air pump is set up, and the air path structure is used to enable the air pump to inflate and deflate all air springs. Since a high-power air pump is set up, there is poor accuracy when inflating air springs with small air volume requirements. It cannot be guaranteed that the inflation effect of the air spring meets the user's precise requirements, affecting the user experience. Summary of the Invention

[0005] In order to address the shortcomings of the existing technology, the present invention provides an air pressure control system and a mattress using the same. By setting a collaborative module in the system to facilitate the coordination of various air pressure adjustment modules, each air pressure adjustment module can not only perform independent inflation and deflation operations for the corresponding air spring to ensure the accuracy of air pressure control, but also can perform coordinated inflation and deflation operations on any air spring through the collaborative module, thereby improving inflation and deflation efficiency and enhancing the user experience.

[0006] The present invention is implemented in the following manner: an air pressure control system comprising:

[0007] The functional module includes a plurality of air springs arranged in a row, wherein the air springs are adjusted in hardness by being inflated and deflated;

[0008] An air pressure regulating module, comprising an air pump and a main air pipe connected between the air pump and the corresponding air spring;

[0009] The coordination module includes an annular auxiliary air pipe connected in series with the main air pipes in each air pressure regulating module and a coordination control valve provided on the auxiliary air pipe in a section between adjacent main air pipes;

[0010] The control module controls the air pressure regulating module to inflate and deflate the corresponding air spring. The coordination module controls multiple air pressure regulating modules to coordinate and inflate and deflate any corresponding air spring, enabling adjustable inflation efficiency for each air spring. Inflation efficiency is specifically reflected in inflation duration or volume.

[0011] By setting up a collaborative module to connect the main air pipes in each air pressure regulating module, the air pump in each air pressure regulating module can switch between independent inflation operation and collaborative inflation operation, which not only ensures that each air pump can inflate and deflate the corresponding air spring and improve the inflation and deflation accuracy, but also can cooperate with multiple adjacent air pumps to perform collaborative inflation operations on one or more air springs, thereby improving inflation and deflation efficiency and enhancing the user experience.

[0012] Preferably, the cooperative control valve is switchable between an on state and a off state, so that adjacent main air pipes can be switched between a mutually connected cooperative inflation state and a mutually isolated independent inflation state. Adjacent main air pipes are connected by a secondary air pipe with a cooperative control valve. When the cooperative control valve is in the on state, the adjacent main air pipes are connected and the corresponding air pumps can work in coordination. When the cooperative control valve is in the off state, the adjacent main air pipes are isolated from each other and the air pumps can operate independently, thereby making the operating mode of the air pump variable and ensuring that the air spring inflation and deflation operations have both good precision and good efficiency.

[0013] Preferably, there are at least four groups of air pressure regulating modules, and the main air pipes of adjacent air pressure regulating modules are connected by opening a cooperative control valve, so that adjacent air pumps can coordinately inflate any corresponding air springs. By providing multiple air pressure regulating modules, the air pressure of each group of air springs can be independently controlled. Auxiliary air pipes with cooperative control valves are provided in the main air pipes of adjacent air pressure regulating modules to ensure that adjacent air pumps can work together and improve the charging and discharging efficiency of any one or more groups of air springs, thereby improving the user experience.

[0014] Preferably, the secondary air pipe is disposed at the front section of the main air pipe near the air pump, and is formed by connecting unit air pipes in series, spanning adjacent main air pipes. The front ends of adjacent main air pipes are connected via the secondary air pipe, allowing the air pump to communicate through the front section of the main air pipe and the spanning secondary air pipe section, thereby ensuring smooth coordinated operation of the air pump.

[0015] Preferably, the air pressure regulating module includes a disconnection control valve provided on the middle section of the main air pipe, the disconnection control valve realizes the switching between the connected state and the closed state with the corresponding air spring by switching on and off, and the air pump connected through the auxiliary air pipe performs a coordinated inflation operation on any corresponding air spring, so that the number of air pumps is greater than the number of air springs and the inflation efficiency of the air spring is improved. The disconnection control valve is connected in series to the middle section of the main air pipe, and plays the role of controlling the switching of the connection and disconnection state between the air pump and the corresponding air spring, ensuring that the air spring can be connected to the air pump through the main air pipe when the air pressure needs to be adjusted, and also ensuring that the air spring is disconnected from the air pump when the air pressure does not need to be adjusted, so that the corresponding air pump can cooperate with the adjacent air pump through the corresponding auxiliary air pipe section, effectively improving the utilization efficiency of the air pump.

[0016] Preferably, the air pressure regulating module includes a three-way exhaust valve connected in series to the main air pipe in the section between the auxiliary air pipe and the on-off control valve, the exhaust port of the three-way exhaust valve being connected to the outside world so that the exhaust three-way valve can switch between an external exhaust state and a sealed state. The exhaust three-way valve is provided with an exhaust port connected to the outside world. When the exhaust three-way valve is switched to the exhaust state, the air in the air spring can be discharged through the exhaust port to reduce the air pressure in the air spring. When the exhaust three-way valve is switched to the sealed state, the air spring can be connected to the air pump through the main air pipe, facilitating the acquisition of high-pressure air and increasing the air pressure.

[0017] Preferably, the air pressure regulation module includes an air pressure sensor disposed on the rear section of the main air pipe. The air pressure sensor senses the air pressure within the air spring through the main air pipe. The air pressure sensor, disposed on the rear section of the main air pipe, is used to detect the air pressure within the air spring and provide a basis for adjusting the air pressure within the air spring, thereby improving the accuracy of air pressure regulation.

[0018] Preferably, the collaborative control valve and the disconnect control valve can be independently switched on and off, so that the air pressure control system can be switched between a collaborative inflation mode in which multiple air pumps are connected to a single air spring, a mixed inflation mode in which multiple air pumps are connected to multiple air springs, and a single inflation mode in which a single air pump is connected to a single air spring. The air pressure control system can be adjusted between multiple modes to meet the differentiated inflation and deflation requirements of each air spring, which not only rationally utilizes each air pressure regulation module, but also improves the user experience by improving the inflation and deflation efficiency. When the air pressure control system is switched to the collaborative inflation mode, multiple air pumps can inflate a single air spring, effectively improving the inflation efficiency of the air spring and shortening the inflation adjustment time; when the air pressure control system is switched to the mixed inflation mode, multiple air pumps can inflate multiple air springs simultaneously, and each air spring controls the connection and disconnection status with the air pump through the corresponding disconnect control valve, ensuring that each air spring can be disconnected from the air pump after reaching the preset air pressure; when the air pressure control system is switched to the single inflation mode, each air spring is connected only to the corresponding air pump, ensuring that the air pressure in each air spring can be accurately adjusted.

[0019] A mattress using the aforementioned air pressure control system comprises a mattress body and a control box. The air pressure regulating module, coordination module, and control module are all disposed within the control box, and the functional module is disposed within the mattress body. One end of the main air pipe is connected to the functional module, while the other end is inserted into the control box and connected to the air pump. The air pressure regulating module, coordination module, and control module are all disposed within the control box. The main air pipe is extended to expose the control box and connect to the functional module disposed within the mattress. This not only protects electrical components and facilitates inspection and maintenance, but also enhances safety by centrally locating live components.

[0020] Preferably, the cushion body comprises an upper quilted layer, a comfort layer, a support layer, and a lower quilted layer stacked in order from top to bottom. The functional module is disposed within the support layer to adjust the hardness of the support layer. The air spring is disposed within the support layer, and the hardness of the support layer is adjusted by adjusting the hardness of the air spring to meet the user's needs.

[0021] The beneficial effects of the present invention are as follows: by setting up a collaborative module to connect the main air pipes in each air pressure regulating module, the air pump in each air pressure regulating module can switch between independent inflation operation and collaborative inflation operation, which not only ensures that each air pump can inflate and deflate the corresponding air spring and improve the inflation and deflation accuracy, but also can cooperate with multiple adjacent air pumps to perform collaborative inflation operations on one or more air springs, thereby improving inflation and deflation efficiency and enhancing the user experience.

[0025] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0026] Example 1:

[0027] This embodiment provides an air pressure control system.

[0028] As shown in Figure 1, an air pressure control system includes a functional module, an air pressure regulating module, a collaborative module and a control module. The control module inflates and deflates the corresponding air spring 1 through the air pressure regulating module, and controls multiple air pressure regulating modules through the collaborative module to cooperate with each other and inflate and deflate any corresponding air spring 1, so that the inflation efficiency of each air spring 1 can be adjusted. The air pressure regulating module and the collaborative module are controlled to cooperate with each other and switch between multiple inflation and deflation modes, which not only meets the air pressure regulation accuracy requirements of the functional module, but also improves the air pressure regulation speed, effectively improving the user experience.

[0029] In this embodiment, the functional module includes a number of air springs 1 arranged in a row. The air springs 1 can adjust the hardness by inflating and deflating air. Different functions are obtained by setting different air springs 1. The air springs 1 include but are not limited to support springs that provide support hardness adjustment and massage springs that provide massage stimulation. The air springs 1 adjust the hardness and height by inflating and deflating air, thereby realizing corresponding functions in various places.

[0030] In this embodiment, the air pressure regulating module includes an air pump 2 and a main air pipe 3 connected between the air pump 2 and the corresponding air spring 1. The air pump 2 runs and is connected to the corresponding air spring 1 through the main air pipe 3. The air pump 2 can be connected to the main air pipe 3 through the air outlet to realize the inflation operation of the air spring 1, and can also be connected to the main air pipe 3 through the air inlet to realize the exhaust operation of the air spring 1, thereby improving the charging and discharging efficiency of the air spring 1 and shortening the air pressure regulation time.

[0031] In this embodiment, the collaborative module includes an annular auxiliary air pipe 4 connected in series with the main air pipe 3 in each air pressure regulating module, and a collaborative control valve 5 provided on the auxiliary air pipe 4 in the section between the adjacent main air pipes 3. The auxiliary air pipe 4 is annular and connected in series with each main air pipe 3, so that each main air pipe 3 can be interconnected and share the airflow driving force generated by the air pump 2 when the collaborative control valve 5 is opened, thereby realizing rapid and effective adjustment of the air pressure of each air spring 1 by collaboratively distributing the airflow driving force, effectively improving the user experience. Specifically, by collaboratively operating multiple air pumps 2 to increase the airflow driving force, the massage stimulation generated by the massage spring can be enhanced by shortening the air pressure increase time, and the softness and hardness adjustment speed of the support spring can be increased by increasing the airflow flow rate.

[0032] In this embodiment, the main air pipe 3 is connected between the air pump 2 and the corresponding air spring 1, and the auxiliary air pipe 4, the three-way exhaust valve 7, the connecting and disconnecting control valve 6 and the air pressure sensor 8 are arranged in sequence from front to back along the main air pipe 3, so that each air conditioning module can be used as a single group or in multiple groups in coordination. Specifically, the auxiliary air pipe 4 is set on the front section of the main air pipe 3, which facilitates the connection between each air pump 2 through the front section of the main air pipe 3 and the auxiliary air pipe 4, ensuring that the airflow driving force is effectively gathered and acts on the target air spring 1; the disconnection control valve 6 is set on the middle section of the main air pipe 3 to control the connection and disconnection state between the air pump 2 and the air spring 1, and then determine the target air spring 1 by opening and closing the disconnection control valve 6; the three-way exhaust valve 7 is set on the section of the main air pipe 3 between the disconnection control valve 6 and the auxiliary air pipe 4, and the high-pressure gas in the air spring 1 can be discharged through the exhaust port when the disconnection control valve 6 is opened; the air pressure sensor 8 is set at the rear section of the main air pipe 3 and close to the air spring 1, so that the air pressure sensor 8 can sense the air pressure in the air spring 1 through the rear section of the main air pipe 3, thereby providing reliable guarantee for precise adjustment of the air pressure.

[0033] In this embodiment, the coordinated control valve 5 can be switched between an open state and a closed state, so that the adjacent main air pipes 3 can be switched between a mutually connected coordinated inflation state and a mutually isolated independent inflation state. When the coordinated control valve 5 is open, the adjacent main air pipes 3 are in a mutually connected coordinated inflation state, and the airflow driving force generated by the adjacent air pumps 2 is enhanced by converging, thereby improving the inflation and deflation efficiency. When the coordinated control valve 5 is closed, the adjacent main air pipes 3 are in a mutually isolated independent inflation state, and the airflow driving force generated by each air pump 2 is applied only to the corresponding air spring 1, ensuring that the air pressure in each air spring 1 can be precisely controlled.

[0034] In this embodiment, there are at least four groups of air pressure regulating modules, and the main air pipes 3 of adjacent air pressure regulating modules are connected by opening the cooperative control valve 5, so that the adjacent air pumps 2 can perform cooperative inflation operations on any corresponding air springs 1. The air pressure regulating modules are set to four groups. The first group of air pressure regulating modules includes No. 1 air pump 2, No. 1 main air pipe 3, No. 1 three-way exhaust valve 7 and No. 1 disconnect control valve 6. The end of No. 1 main air pipe 3 is connected to No. 1 air spring 1, and so on. No. 1 cooperative control valve 5 is set on the auxiliary air pipe 4 section between No. 1 main air pipe 3 and No. 2 main air pipe 3. And so on, No. 4 cooperative control valve 5 is set on the auxiliary air pipe 4 section between No. 4 main air pipe 3 and No. 1 main air pipe 3. The cooperative control valve 5 and the disconnect control valve 6 can be switched on and off independently, and the air pressure control system can operate in different modes, including but not limited to:

[0035] In single inflation mode, a single air pump 2 is connected to a single air spring 1, all cooperative control valves 5 are closed, and the air pump 2 in each group of air pressure regulating modules is connected to the corresponding air spring 1 by opening and closing the corresponding connecting control valve.

[0036] In the coordinated inflation mode, multiple air pumps 2 are connected to a single air spring 1, and adjacent air pressure regulating modules inflate the single air spring 1 by opening the corresponding coordinated control valve 5. For example, if the No. 1 coordinated control valve 5 and the No. 1 disconnect control valve 6 are opened, and the No. 2 disconnect control valve 6 is closed, the airflow driving force generated by the No. 1 and No. 2 air pumps 2 can act on the No. 1 air spring 1 simultaneously, and the air pressure in the No. 2 air spring 1 remains unchanged. For another example, if the No. 1 coordinated control valve 5, the No. 2 coordinated control valve 5, and the No. 1 disconnect control valve 6 are opened, and the No. 2 disconnect control valve 6 and the No. 3 disconnect control valve 6 are closed, the airflow driving force generated by the No. 1, No. 2, and No. 3 air pumps 2 can act on the No. 1 air spring 1 simultaneously, and the air pressure in the No. 2 and No. 3 air springs 1 remains unchanged. During this process, the air pressure regulating modules that do not participate in the coordinated operation can be in the single inflation mode and independently adjust the air pressure of the corresponding air spring 1.

[0037] In the mixed inflation mode, multiple air pumps 2 are connected to multiple air springs 1, and the adjacent air pressure regulating modules inflate the multiple corresponding air springs 1 by opening the corresponding cooperative control valves 5, and sense the air pressure in the corresponding air springs 1 through the air pressure sensor 8, and achieve pressure stabilization by closing the corresponding disconnection control valve 6 after reaching the preset air pressure, so as to ensure that the air pressure in the air spring 1 is maintained within the preset pressure range. For example, by opening the No. 1 cooperative control valve 5, the No. 1 disconnection control valve 6 and the No. 2 disconnection control valve 6, the airflow driving force generated by the No. 1 air pump 2 and the No. 2 air pump 2 can act on the No. 1 air spring 1 and the No. 2 air spring 1 at the same time, and the control module senses the air pressure in the No. 1 air spring 1 and the No. 2 air spring 1 through the No. 1 air pressure sensor 8 and the No. 2 air pressure sensor 8 and closes the corresponding No. 1 disconnection control valve 6 and the No. 2 disconnection control valve 6 after reaching the preset air pressure range; for another example, by opening the No. 1 cooperative control valve 5, the No. 2 cooperative ... The control valve 5, the No. 1 disconnect control valve 6, and the No. 2 disconnect control valve 6 are closed, and the No. 3 disconnect control valve 6 is closed. Then, the airflow driving force generated by the No. 1 air pump 2, the No. 2 air pump 2, and the No. 3 air pump 2 can act on the No. 1 air spring 1 and the No. 2 air spring 1 at the same time, and the air pressure of the No. 3 air spring 1 remains unchanged. The control module senses the air pressure in the No. 1 air spring 1 and the No. 2 air spring 1 through the No. 1 air pressure sensor 8 and the No. 2 air pressure sensor 8 and closes the corresponding No. 1 disconnect control valve 6 and No. 2 disconnect control valve 6 when the preset air pressure range is reached. During this process, the air pressure regulating module that does not participate in the coordination can be in a single inflation mode and independently adjust the air pressure of the corresponding air spring 1.

[0038] In this embodiment, the air pumps 2 in each air pressure regulating module can be configured with differentiated parameters, which not only meets the differentiated requirements of the corresponding air springs 1, but also achieves differentiated matching effects through cooperation, which should also be regarded as a specific implementation method of this embodiment. For example, when air pumps 2 No. 1 and 2 are low-flow air pumps 2, and air pump 2 No. 3 is a high-flow air pump 2, then air pump 2 No. 2 can achieve a matching effect with differentiated flow by cooperating with air pump 2 No. 1 or air pump 2 No. 3, respectively.

[0039] In this embodiment, the auxiliary air pipe 4 is arranged at the front section of the main air pipe 3 near the air pump 2. The auxiliary air pipe 4 is formed by connecting unit air pipes in series across adjacent main air pipes 3. The auxiliary air pipe 4 includes several sections of unit pipes arranged between adjacent main air pipes 3. Adjacent unit pipes are connected by the main air pipes 3 arranged at corresponding ends to form a ring shape, which facilitates the convergence of the airflow driving force generated by the air pump 2 and concentrates it on the target air spring 1.

[0040] In this embodiment, the air pressure regulation module includes a disconnection control valve 6 disposed in the middle section of the main air pipe 3. The disconnection control valve 6 switches between a connected state and a closed state with the corresponding air spring 1 by switching on and off. The air pump 2 connected through the auxiliary air pipe 4 performs a coordinated inflation operation on any corresponding air spring 1, thereby increasing the number of air pumps 2 to be greater than the number of air springs 1 and improving the inflation efficiency of the air springs 1. When the disconnection control valve 6 is switched to the connected state, the front and rear sections of the main air pipe 3 are connected, allowing the corresponding air spring 1 to be pressure-regulated through the main air pipe 3. When the disconnection control valve 6 is switched to the closed state, the front and rear sections of the main air pipe 3 are disconnected, making the air pressure in the corresponding air spring 1 unadjustable and remaining constant.

[0041] Preferably, the air pressure regulating module includes a three-way exhaust valve 7 connected in series on the main air pipe 3 in the section between the auxiliary air pipe 4 and the disconnect control valve 6. The exhaust port of the three-way exhaust valve 7 is connected to the external space so that the exhaust three-way valve can switch between an external exhaust state and a closed state. The three-way exhaust valve 7 includes a first port connected to the front section of the main air pipe 3, a second port connected to the disconnect control valve 6, and a third port forming an exhaust port. When the three-way exhaust valve 7 is switched to the exhaust state, the third port is connected to the second port, and the air flow in the air spring 1 enters the three-way exhaust valve 7 through the opened disconnect control valve 6 and is discharged through the third port. When the three-way exhaust valve 7 is switched to the closed state, the first port is connected to the second port, and the air spring 1 is connected to the air pump 2 through the main air pipe 3, so that the air spring 1 can receive the air flow driving force from the air pump 2 and realize rapid air pressure regulation.

[0042] Preferably, the air pressure regulating module includes an air pressure sensor 8 provided on the rear section of the main air pipe 3, and the air pressure sensor 8 senses the air pressure in the air spring 1 through the main air pipe 3. The sensing portion of the air pressure sensor 8 is exposed in the rear section of the main air pipe 3 and is located in the same connected space as the air spring 1, so that the air pressure sensor 8 can sense the air pressure in the air spring 1 through the main air pipe 3, thereby providing a basis for the control module to accurately control the air pressure in the air spring 1.

[0043] Example 2:

[0044] Compared with the first embodiment, this embodiment provides a mattress.

[0045] The mattress shown in Figure 2 includes a mattress body and a control box 9. The air pressure regulating module, coordination module, and control module are all housed within the control box 9. The functional modules are housed within the mattress body. One end of the main air pipe 3 is connected to the functional modules, while the other end is inserted into the control box 9 and connected to the air pump 2. The rear end of the main air pipe 3 extends and is exposed outside the control box 9, where it is connected to the corresponding functional modules. This ensures that the air pressure regulating module, coordination module, and control module can all be housed within the control box 9, ensuring safe use and electrical component safety, facilitating maintenance, and ensuring that the functional modules can perform their corresponding functions through inflation and deflation, enhancing the user experience.

[0046] In this embodiment, the cushion body includes an upper quilted layer 10, a comfort layer 12, a support layer 13, and a lower quilted layer 11 stacked in sequence from top to bottom. The upper quilted layer 10 and the lower quilted layer 11 are vertically stacked and wrap around the comfort layer 12 and the support layer 13, protecting and positioning the comfort layer 12 and the support layer 13.

[0047] In this embodiment, the functional module is disposed within the support layer 13. The functional module includes support springs densely arranged in a matrix at the bottom of the support layer 13 and massage springs disposed above the support springs. The hardness of the support layer 13 is adjusted by adjusting the air pressure within the support springs. The air pressure within the massage springs is adjusted to drive them to expand and contract vertically, thereby providing upward massage stimulation under the support of the support springs, providing a comfortable lying experience for the user.

[0048] In this embodiment, due to the differences in the airflow characteristics required by the support spring and the massage spring, different air pumps 2 are required within the corresponding air pressure regulation modules. Specifically, the support spring is larger in volume, requiring an air pump 2 with a higher flow rate, while the massage spring requires greater hardness to produce massage stimulation, requiring an air pump 2 with a higher air pressure. For the user, different types of air pumps 2 can not only meet the air pressure regulation requirements of their respective air springs 1, but also enhance the user experience through synergy, effectively shortening the air pressure regulation speed and improving the air pressure regulation accuracy.
