A control box and mattress capable of uniform exhaust

Abstract

This utility model relates to a control box and mattress capable of uniformly venting air. Existing airbags vent air naturally through the pressure difference with the external space, resulting in significant variations in flow rate. This utility model includes a housing, an air pump, and a main control unit. The air pump has an air intake port and an air inflation port. A secondary control unit is located between the main control unit and the air pump. The secondary control unit includes an air intake adjustment component and an air inflation adjustment component. The air intake port can be connected to the main control unit through the air intake adjustment component, and the air inflation port can be connected to the external space through the air inflation adjustment component. This allows the gas in the target space to be uniformly vented after passing through the air intake adjustment component and the air inflation adjustment component sequentially under the drive of the air pump. The secondary control unit is used to change the airflow direction, enabling the air pump to independently perform inflation and deflation operations on each target space. This effectively increases the airflow in the later stages of deflation, utilizing the power of the air pump to improve deflation efficiency and effect, while also effectively reducing the airflow in the early stages of deflation, lowering noise, and improving the user experience.

Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a control box and a mattress. Background Technology

[0002] Existing mattresses include a mattress body with internal air bladders and a control box for adjusting the air pressure within the mattress. The control box includes a housing and an air pump and control unit housed within the housing. The air pump has an air intake port and an air inflation port. The air inflation port of the air pump is connected to the corresponding air bladder through the control unit. During inflation, the air pump draws in outside air through the air intake port and compresses it to form high-pressure air that is delivered outward through the air inflation port. The high-pressure air is input into the air bladder through the control unit, increasing the air pressure inside the air bladder and enhancing the firmness of the mattress body. During deflation, the air inside the air bladder is directly discharged to the outside space through the control unit. The air discharge flow rate varies depending on the air pressure difference between the air bladder and the outside space, resulting in significant variations in flow rate. The greater the air pressure difference, the higher the discharge efficiency, and vice versa. This leads to inconsistent efficiency when the air bladder deflates. When the air pressure between the air bladder and the outside space decreases, the air discharge efficiency also decreases, which in turn affects the sensitivity of the firmness adjustment due to low air discharge efficiency, impacting the user experience. In addition, when the air pressure difference between the airbag and the outside space is large, the air exhaust velocity is high, which will generate more noise and affect the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a control box and mattress capable of uniformly exhausting air. Air in the target space is uniformly exhausted through an air pump, which effectively increases the airflow in the later stage of exhaust, improves exhaust efficiency, and also effectively reduces the airflow in the early stage of exhaust, reduces noise, and enhances the user experience.

[0004] This utility model is achieved through the following method: a control box for uniformly venting exhaust includes a housing, an air pump, and a main control unit disposed within the housing. The air pump has an air intake port and an air filling port. The main control unit can communicate with at least one target space. A secondary control unit is disposed between the main control unit and the air pump. The secondary control unit includes an air intake adjustment component disposed at the air intake port and an air filling adjustment component disposed at the air filling port. The air intake port can communicate with the main control unit through the air intake adjustment component, and the air filling port can communicate with the external space through the air filling adjustment component, so that the gas in the target space is uniformly vented after passing through the air intake adjustment component and the air filling adjustment component in sequence under the drive of the air pump. The secondary control unit is disposed between the air pump and the main control unit to change the airflow direction, so that the air pump can independently perform air filling and air venting operations to each target space. This effectively increases the airflow in the later stage of exhaust, uses the power of the air pump to improve exhaust efficiency and exhaust effect, effectively removes residual air in the target space, and also effectively reduces the airflow in the early stage of exhaust, reduces noise, and improves the user experience.

[0005] Preferably, the air extraction regulating component includes a main outlet communicating with the air extraction port, a first inlet communicating with the external space, and a second inlet communicating with the main control unit. The air extraction regulating component can switch between an external extraction state where the main outlet and the first inlet are connected, and an internal extraction state where the main outlet and the second inlet are connected. The air extraction regulating component is used to switch the air source of the air pump's air extraction port, ensuring that the air pump can extract outside air and deliver it to the target space for inflation, and also ensuring that the air pump can extract air from the target space and deliver it to the external space for exhaust.

[0006] Preferably, the inflation regulating component includes a main inlet connected to the inflation port, a first outlet connected to the external space, and a second outlet connected to the main control unit. The air extraction regulating component can switch between an external discharge state where the main inlet and the first outlet are connected, and an internal discharge state where the main inlet and the second outlet are connected. The inflation regulating component is used to switch the air source destination of the air pump's inflation port, ensuring that the air pump can draw in outside air and deliver it to the target space for inflation, and also ensuring that the air pump can draw in air from the target space and deliver it to the external space for deflation.

[0007] Preferably, when the air extraction regulator is switched to the external extraction state and the inflation regulator is switched to the internal dissipation state, outside air is uniformly input into the target space through the air pump; when the air extraction regulator is switched to the internal extraction state and the inflation regulator is switched to the external dissipation state, air in the target space is uniformly discharged into the outside space through the air pump. The air extraction regulator controls the air source of the air pump, and the inflation regulator controls the destination of the high-pressure gas generated by the air pump. Through their cooperation, the air pump can independently perform inflation and deflation operations on the target space.

[0008] Preferably, both the air extraction regulating component and the air inflation regulating component are three-way valves. This not only allows for the use of standard components to reduce costs but also facilitates control and improves control accuracy.

[0009] Preferably, the main control unit includes a main pipe connected to the secondary control unit and several unit valves connected to the main pipe. Each unit valve corresponds to a specific target space, allowing each target space to be switched on and off from the main pipe via its corresponding unit valve. The main pipe serves to transport airflow, including airflow from the secondary control unit to the main control unit during inflation and airflow from the main control unit to the secondary control unit during deflation. The main control unit contains multiple unit valves, allowing the air pipe to be independently connected and disconnected from its corresponding target space via the unit valves, thereby enabling independent adjustment of the air pressure within each target space.

[0010] Preferably, the main pipe end is bifurcated and selectively connected to either the inflation adjustment component or the deflation adjustment component. The main pipe end obtains two independent ports through the bifurcation, and each port is linked to the inflation adjustment component and the deflation adjustment component respectively, ensuring that the main pipe can be shared by the inflation adjustment component and the deflation adjustment component.

[0011] Preferably, the housing is equipped with a suspension system, and the air pump, main control unit, and auxiliary control unit are all suspended on the suspension system via shock-absorbing strips. The suspension system is mounted inside the housing via shock-absorbing feet, and the air pump, main control unit, and auxiliary control unit are all suspended on the suspension system via shock-absorbing strips. The shock-absorbing feet and shock-absorbing strips utilize their own deformation to eliminate vibrations generated during operation, thereby reducing operating noise.

[0012] A mattress includes a mattress body, within which a control box and at least one airbag forming the target space are provided. The control box inflates and deflates the airbags to ensure uniform air pressure changes within them. The control box can independently inflate and deflate each airbag, effectively improving the precision and efficiency of airbag firmness adjustment, reducing operating noise, and enhancing the user experience.

[0013] Preferably, the cushion includes a support layer, and the airbag is a support bladder disposed within the support layer. The support bladder is used to support the user, providing the user with suitable support and improving lying comfort.

[0014] Preferably, the pad includes a massage layer, and the airbag is a massage bladder disposed within the massage layer. The massage bladder expands and contracts by repeatedly inflating and deflating, thereby applying a massage force to the user and providing a relaxing experience.

[0015] Preferably, the pad body has a perimeter edging, and the pad body is covered with an outer cover. The edging serves to enhance the perimeter support of the pad body and to protect and position the support layer. The outer cover encloses the edging and the pad body, providing protection and facilitating disassembly and cleaning, thus improving the user experience.

[0016] The beneficial effects of this utility model are as follows: A secondary control unit is set between the air pump and the main control unit. The secondary control unit is used to change the airflow direction, so that the air pump can independently carry out inflation and deflation operations to each target space. This not only effectively increases the airflow in the later stage of deflation, but also uses the power of the air pump to improve the deflation efficiency and effect, effectively removes residual air in the target space, and effectively reduces the airflow in the early stage of deflation, reduces noise, and improves the user experience.

[0023] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1:

[0025] This embodiment provides a control box.

[0026] like Figure 1 and 2 The control box shown includes a housing and an air pump and a main control unit housed within the housing. The air pump has an air intake port and an air filling port. The main control unit can communicate with at least one target space. A secondary control unit is located between the main control unit and the air pump. The secondary control unit includes an air intake adjustment component located at the air intake port and an air filling adjustment component located at the air filling port. The air intake port can communicate with the main control unit through the air intake adjustment component, and the air filling port can communicate with the external space through the air filling adjustment component. This allows gas in the target space to be uniformly discharged after passing through the air intake adjustment component and the air filling adjustment component sequentially under the drive of the air pump. The secondary control unit, located between the air pump and the main control unit, is used to change the airflow direction, enabling the air pump to independently perform air filling and air venting operations to each target space. This effectively increases the airflow in the later stage of exhaust, utilizes the power of the air pump to improve exhaust efficiency and effect, effectively removes residual air in the target space, and also effectively reduces the airflow in the early stage of exhaust, lowers noise, and improves the user experience.

[0027] In this embodiment, the air extraction regulating component is a three-way valve (e.g., Figure 3As shown in the figure, the air extraction regulating component includes a main outlet connected to the air extraction port, a first inlet connected to the external space, and a second inlet connected to the main control unit. The air extraction regulating component can switch between an external extraction state where the main outlet is connected to the first inlet and an internal extraction state where the main outlet is connected to the second inlet, so that the air pump can be connected to different spaces through the air extraction regulating component, thereby providing different air sources for the air pump.

[0028] In this embodiment, the inflation regulating component is a three-way valve. The inflation regulating component includes a main inlet connected to the inflation port, a first outlet connected to the external space, and a second outlet connected to the main control unit. The air extraction regulating component can switch between an external discharge state where the main inlet and the first outlet are connected and an internal discharge state where the main inlet and the second outlet are connected, so that the air pump can be connected to different spaces through the inflation regulating component, and the high-pressure air generated by the air pump can be provided to different destinations.

[0029] In this embodiment, the air extraction adjustment component and the air inflation adjustment component cooperate with each other to enable the control box to independently perform air inflation and air deflation operations on the target space.

[0030] When it is necessary to inflate the target space, the air extraction adjustment device is switched to the external extraction state, and the inflation adjustment device is switched to the internal discharge state. Outside air is then uniformly introduced into the target space through the air pump. Specifically, outside air is sequentially introduced into the corresponding target space through the first inlet, main outlet, air extraction port, air pump, inflation port, main inlet, second outlet, main pipe, and corresponding unit valve.

[0031] When venting is required in the target space, the air extraction regulator is switched to internal extraction mode, and the air filling regulator is switched to external exhaust mode. Air in the target space is then uniformly discharged into the external space via an air pump. Specifically, the air in the target space sequentially passes through the corresponding unit valve, main pipe, second inlet, extraction port, air pump, inflation port, main inlet, and first outlet before being discharged into the external space. Because the air pump's power is constant, the exhaust airflow remains consistent until all air in the target space is completely exhausted.

[0032] In this embodiment, the main control unit includes a main pipe connected to the secondary control unit and several unit valves connected to the main pipe. Each unit valve corresponds to a specific target space, allowing each target space to switch between connection and disconnection with the main pipe via its corresponding unit valve. The main pipe spans between the main control unit and the secondary control unit. One end of the main pipe is branched and selectively connected to either an inflation regulator or a deflation regulator, facilitating separate connections. The other end is sequentially connected to a row of unit valves, ensuring that each unit valve is connected to the main pipe. This allows for connection and disconnection control between the main pipe and the corresponding target space via the unit valves. The main control unit selects the target space to connect to the main pipe, ensuring that each target space can independently connect to the main pipe. The secondary control unit switches the function of the air pump, selecting between inflation and deflation functions. The main and secondary control units cooperate to perform inflation or deflation operations on specific target spaces.

[0033] In this embodiment, a suspension (such as) is provided inside the housing. Figure 4 As shown, the air pump, main control unit, and auxiliary control unit are all suspended on the suspension via shock-absorbing strips. The suspension is mounted inside the housing via shock-absorbing feet, and the air pump, main control unit, and auxiliary control unit are all suspended on the suspension via shock-absorbing strips. The shock-absorbing feet and shock-absorbing strips utilize their own deformation to eliminate vibrations generated during operation, thereby reducing operating noise.

[0034] Example 2:

[0035] Compared to Embodiment 1, this embodiment provides a mattress.

[0036] like Figure 5 The mattress shown includes a mattress body, within which a control box and at least one airbag forming the target space are provided. The control box inflates and deflates the airbags to ensure uniform air pressure changes within them. The control box can independently inflate and deflate each airbag, effectively improving the precision and efficiency of airbag firmness adjustment, reducing operating noise, and enhancing the user experience.

[0037] In this embodiment, the cushion includes a support layer, and the airbag is a support bladder disposed within the support layer. The support bladder is used to support the user, providing appropriate support and improving lying comfort.

[0038] In this embodiment, the pad includes a massage layer, and the airbag is a massage bladder disposed within the massage layer. The massage bladder expands and contracts by repeatedly inflating and deflating, thereby applying a massage force to the user and providing a relaxing experience.

[0039] In this embodiment, the pad body has a perimeter edging, and the pad body is covered by an outer cover. The edging serves to enhance the perimeter support of the pad body and to protect and position the support layer. The outer cover encloses the edging and the pad body, providing protection and facilitating disassembly and cleaning, thus improving the user experience.

[0040] The other structures and effects of the control box described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
