Detailed Description
The invention is further described with reference to the following figures and detailed description of embodiments.
The present invention is intended to provide a pneumatic mattress device, for example, in the form of an amusement game mattress, the surface of which can be simultaneously brought into a state of rising and falling, so that a user can feel the sense of comfort and fun brought about by such rising and falling on the surface of the mattress device, while the number of air pumps used is as small as possible. Therefore, the following technical scheme is provided in a specific embodiment of the invention:
referring to fig. 1 and 2, a pneumatic cushion device includes a controller and at least one set of undulation cells, the surfaces of which may assume overlapping undulation states; the heave unit group comprises at least one first air bag (such as 1, 3 and 5), at least one second air bag (such as 2, 4 and 6) and a first air pump A and a second air pump B; the controller is used for controlling the working states of the first air pump A and the second air pump B, when the first air pump A works, gas can be pumped from the second air bag (for example, 2, 4, 6) which is inflated to inflate the first air bag (for example, 1, 3, 5) in the state to be inflated, so that the first air bag (for example, 1, 3, 5) and the second air bag (for example, 2, 4, 6) are in a first lodging state in the working time of the first air pump A; when the second air pump B is operated, air can be pumped from the inflated first air bag (for example 1, 3, 5) to inflate the second air bag (for example 2, 4, 6) in the state to be inflated, so that the first air bag and the second air bag can present a second heave state in the operation time of the second air pump B; wherein the first undulating state is the first balloon being deflated and the second balloon being deflated, the second undulating state is the first balloon being deflated and the second balloon being inflated, and the first undulating state and the second undulating state are such that the surfaces of the set of undulating units assume a state of overlapping undulations.
The cushion body device can only have one fluctuation unit group, and the fluctuation unit group can only have one first air bag, one second air bag and two air pumps; there may also be more than two heave unit groups, each heave unit group having more than two first airbags, more than two second airbags and two air pumps. The cushion device as exemplified in fig. 2 and 3 includes only one heave unit group consisting of six air cells and two air pumps, three first air cells 1, 3, 5, and three second air cells 2, 4, 6. The number of relief unit groups and the number of air cells in each relief unit group are only exemplary and not intended to limit the invention, and may be designed according to the specific product form and requirements.
In a preferred embodiment, the first air pump and the second air pump are alternately operated under the control of the controller so that the first air cell and the second air cell alternately undulate. For example, during the current time period (e.g., 3 seconds), the first air pump a is on and the second air pump B is off, and as illustrated in fig. 2 and 3, the first air pump a may draw air from the second air bags 2, 4, and 6 to inflate the first air bags 1, 3, and 5; and in the next 3 seconds, the controller controls the first air pump A to stop working and the second air pump B to work, so that the second air pump B can pump air from the first air bag to inflate the second air bag. The first air pump and the second air pump continuously and alternately work to enable the first air bag and the second air bag to alternately fluctuate.
In another embodiment, the first air pump and the second air pump do not need to be strictly operated alternately, and the operation time of the first air pump and the operation time of the second air pump may be partially overlapped. In the above example, assuming that the duration of each operation of the first air pump and the second air pump is 3 seconds and the time for stopping the operation is 1 second, the following conditions are taken: in the current 3 seconds, the first air pump A works, and when the 3 rd second of the current 3 seconds starts, the second air pump B also starts to work; thus, when the first air pump a stops operating, the second air pump B will continue to operate for 2 seconds and then stop operating again after the first air pump a and the second air pump B both stop for 1 second.
In the photovoltaic unit group, the air circuit connection mode between the air pump and the air bag is as follows: the air outlet A2 of the first air pump A is connected with the inflation inlet 11 of the first air bag (taking the air bag 1 as an example), and the air inlet A1 of the first air pump A is connected with the air suction port of the second air bag; the air outlet B2 of the second air pump B is connected with the inflation inlet of the second air bag, and the air inlet B1 of the second air pump B is connected with the air pumping port 12 of the first air bag. When the first airbag and the second airbag are each provided with a plurality of (two or more), the first airbag and the second airbag are alternately arranged regularly or irregularly.
For example, as illustrated in fig. 3, the first air cells and the second air cells are alternately arranged, the inflation ports of the first air cells 1, 3 and 5 are all connected to the air outlet port a2 of the first air pump a, and the suction ports of the first air cells 1, 3 and 5 are all connected to the air inlet port B1 of the second air pump B; the inflation ports of the second air bags 2, 4 and 6 are all connected to the air outlet port B2 of the second air pump B, and the suction ports of the second air bags 2, 4 and 6 are all connected to the air inlet port a1 of the first air pump a. In this way, when the first air pump a is operated, the three first air bags 1, 3 and 5 in the state to be inflated can be inflated by extracting gas from the three inflated second air bags 2, 4 and 6, so that the second air bags are deflated during the operation time of the first air pump a, and the first air bags are inflated during the operation time of the first air pump a, so that the overall surface formed by the first air bags and the second air bags is in a wavy state (the first air bags are inflated, the second air bags are fallen); then, when the second air pump B is operated, air is pumped from the inflated first air bags 1, 3 and 5 to inflate the second air bags 2, 4 and 6 in the state to be inflated, so that the overall surface formed by the first air bags and the second air bags presents a wavy state (first air bags fall, second air bags, etc.), and the surfaces of the wavy unit group can present a state of continuous overlapping undulation through the alternate operation of the first air pump a and the second air pump B.
In an embodiment, the integral surface of the first balloon and the second balloon, i.e. the integral surface of the group of undulated units, may be realized by: joining (e.g., sewing or bonding) adjacent balloons without communicating the balloon lumens. Alternatively, as shown in FIGS. 1 and 2, a flexible cover 10 may be added to form an integral surface (i.e., the surface that contacts the user) of the pad device. When the surface of the relief unit group (in particular to the front surface of the user activity, and the opposite surface is the back surface) is in an overlapped and relieved state due to the alternate relief of the first air bag and the second air bag, the flexible coating layer is also in an overlapped and relieved state, so that the user can feel comfortable when the user moves or has a rest on the surface of the cushion body device.
In a specific embodiment, the connection air path between the air bag of the undulation unit group and the air pump for inflating and deflating the undulation unit group may be embedded under the flexible coating layer 10, for example. As illustrated in fig. 3, the air outlet a2 of the air pump a is simultaneously connected to the inflation ports of the first air bags 1, 3, 5 through inflation lines (black solid lines), and the air inlet a1 is simultaneously connected to the suction ports of the second air bags 2, 4, 6 through suction lines (black dotted lines); the air outlet B2 of the air pump B is simultaneously connected with the inflation ports of the second group of air bags 2, 4 and 6 through another inflation pipeline (black solid line), and the air inlet B1 is simultaneously connected with the air pumping ports of the first group of air bags 1, 3 and 5 through another air pumping pipeline (black dotted line).
The cushion body device of the embodiment of the invention can be presented in the forms of entertainment and leisure cushions (such as baby crawling cushions, outdoor picnic cushions), sofa cushions or bed cushions, and the like. The invention is preferably described in terms of an amusement crawling mat for infants and young children, the overlapping undulations presented by the surface of the device being able to give the baby a sense of comfort and strong enjoyment when playing on the mat body. Especially when the baby is sleepy, the baby can easily fall asleep while lying on the bed.
In some embodiments, an air valve which can be opened/closed manually or under the control of a controller is arranged at the air inlet of at least one air pump in each of the undulation unit groups, and the air valve is mainly used when the cushion body device is initially used. Specifically, when the cushion device is initially used, all the air bags are normally in an uninflated state, that is, the first air bag and the second air bag are in a state to be inflated, and in this case, in each heave unit group, the first air bag or the second air bag needs to be initially inflated. For example, a first air bag (1, 3, 5, etc.) is initially inflated, the air valve at the air inlet a1 of the first air pump a can be controlled to be opened to draw air from the outside to initially inflate the first air bag; or, the air valve at the air inlet B1 of the second air pump B is controlled to be opened to draw air from the outside to carry out initial inflation on the second air bag (2, 4, 6, etc.); after the initial inflation is completed, the air valve is closed, and then air does not need to be drawn from the outside in the process.
For example, as illustrated in fig. 3, when the initial inflation is completed, the air pump a is controlled to operate for the current 3 seconds, and the air pump B is not operated, so that the air pump a evacuates air from the second airbags 2, 4, and 6 within the 3 seconds while the evacuated air is used to inflate the first airbags 1, 3, and 5; and in the next 3 seconds, controlling the air pump A to stop and the air pump B to work so as to pump the first air bag and inflate the second air bag. So as to realize the alternating fluctuation of the first and the second air bags in the fluctuation unit group, and the flexible coating layer fluctuates along with the fluctuation of the air bags. Of course, the working cycle of the inflation/deflation air pump of the air bag can be defined and set according to the size and the number of the air bags, the fluctuation speed, the user comfort level and other aspects.
If the pad body area of the pad body device is large, the number of air bags is large, and the requirement for variability of the overlapping undulation state of the surface is high, more than two undulation unit groups, such as the two undulation unit groups 100 and 200 illustrated in fig. 4, may be provided, each of which is inflated and deflated by two air pumps. The number of the first cells and the number of the second cells may be plural in each of the undulation units, for example, the number of the first cells may be 10, the number of the second cells may be 10, and the first cells and the second cells may be alternately arranged in each of the undulation units or between two of the undulation units so that the surface of the cushion device exhibits a variety of overlapping undulation states. For example, as shown in FIG. 4, the air paths and the air flow direction thereof are represented by the arrowed lines in FIG. 4, and in this exemplary cushion device, four air pumps can be controlled by the controller: at the time t1, controlling the air pump A to work and the air pump B to stop; at the time t1+2, the air pump C is controlled to work and the air pump D is controlled to stop; at the time t1+4, the air pump A is controlled to stop and the air pump B is controlled to work; at the time t1+6, the air pump C is controlled to stop and the air pump D is controlled to work; at the time t1+8, controlling the air pump A to work and the air pump B to stop; … …, performed in this manner, a richer variety of alternating undulations can be achieved than in fig. 3.
Referring to fig. 1 and 2, in a preferred embodiment, the cushion device further comprises at least one inflatable pneumatic bladder (e.g., 20, 30, etc.), and may even further comprise a third air pump (not shown) dedicated to inflating the pneumatic bladder, although it is preferred that the pneumatic bladder be inflated by the first or second air pump. The pneumatic soft body can be arranged on the air bag, for example, the first air bag and/or the second air bag are provided with mounting holes, mounting connecting components are arranged in the mounting holes, and the pneumatic soft body is mounted on the air bag through the mounting connecting components. The pneumatic soft body (20, 30, etc.) is provided with an inflation port and a deflation hole (such as 21, 31 in the figures), and the pneumatic soft body can be inflated by the first, the second or the third air pump. The waving principle of the pneumatic soft body is that when the air pump inflates the pneumatic soft body, the inflation inlet of the pneumatic soft body admits air and the air release hole releases air, so that the pneumatic soft body can wave under the impact of air.
And air valves can be arranged on the inflation pipelines and the air exhaust pipelines of the first air pump and the second air pump. In the case of inflation of the pneumatic software by the first or second air pump: in the alternate waving process of the first air bag and the second air bag, if the pneumatic soft body waving is needed, the first air pump or the second air pump can work all the time, and the fluctuation of the air bags is realized by controlling the on-off of the air valves on the air paths connecting the air bags and the air pumps. For example, when the first air bags 1, 3 and 5 need to be inflated and the second air bags 2, 4 and 6 need to be deflated, the air valves on the connecting air paths between the second air pump B and the air bags are controlled to be closed, at this time, the second air pump can work simultaneously with the first air pump, but the second air pump B works to inflate the pneumatic soft body to make the pneumatic soft body swing. If the pneumatic software is waved by the inflation of the first air pump A, the air valves on the air paths between the first air pump A and the air bags need to be controlled to be closed in the process that the first air bags 1, 3 and 5 are deflated and the second air bags 2, 4 and 6 are inflated, so that the first air pump A only inflates the pneumatic software.
In a preferred embodiment, the number of the pneumatic soft bodies is multiple, and the pneumatic soft bodies are mainly distributed on the surface of the cushion body device close to the edge, and the number and the arrangement position are not limited by the invention. The inflation ports of the pneumatic soft bodies are connected to the first, second or third air pumps through inflation pipelines. More preferably, an air valve 40 is arranged at an air inflation port of the pneumatic soft body and used for controlling the on-off of an air path between the pneumatic soft body and the first, second or third air pump. For example, when the air valve of the pneumatic software 20 is opened and the first, second or third air pump is in operation, the pneumatic software can be waved.
In one embodiment, the pneumatic soft air valve is arranged on the corresponding mounting component of the pneumatic soft body. The connection between the pneumatic soft body and its mounting assembly is, for example, a screw-type connection, and has a certain sealing property after being connected. In addition, the air-escape hole of the pneumatic soft body is preferably located at the top. The pneumatic soft body is various cartoon characters or animal figures, and the air leakage holes are located on the heads or hands of the cartoon characters. In another embodiment, sounding components can be arranged on the pneumatic soft body, and when the pneumatic soft body waves, the components can sound under the action of the waves. The principle of the sounding components sounding under the waving is similar to the principle of the wind bells sounding under the action of the wind by swinging and collision, for example, a plurality of small iron rings or small iron bars or small bells with lighter weight are arranged on the pneumatic soft body, the small iron rings or the small iron bars collide with each other to generate sound when the pneumatic soft body waves, and the small bells also generate sound due to swinging; therefore, when the pneumatic soft body is waved, the toy is interesting not only visually, but also attracts the attention of the baby through sound, thereby increasing certain interestingness.
In a preferred embodiment, in order to realize the alternate waving state of the plurality of pneumatic soft bodies, the air valves of different pneumatic soft bodies can be controlled to be opened at different times and closed at different times during the continuous working process of the third air pump, so that the rich and varied alternate waving can be presented.
Referring to fig. 1 and 2, in other preferred embodiments, the mat device may further include a sensing device connected to the controller, the sensing device is used for acquiring exercise status information of an infant on the mat device and sending the exercise status information to the controller, and the controller controls the air valve of the pneumatic software at a predetermined position to open according to the received exercise status information, so that the pneumatic software at the predetermined position can dance under the inflation action of the first, second or third air pumps, and the purpose is to attract the attention of the baby and guide crawling. The setting position of the sensing device is not limited as long as the real-time motion state information of the infant on the device can be obtained, and the sensing device can be arranged between the flexible coating layer and the air bag, can be attached to the inner side surface of the air bag and the like.
In a preferred embodiment, the sensing device is a pressure sensor (50, 60, etc.), a displacement sensor, a vibration sensor, etc., and the present invention is not limited thereto, and any sensor may be used as long as it can acquire information on the movement of the user on the mat device. The sensors are distributed at different points and are all connected to the controller and are used for receiving pressure signals, vibration signals, displacement signals and the like generated by the baby on the pad body device; the controller can control the air valve of a specific pneumatic software to open according to the signals. For example, when pressure sensors are used, the controller can judge the movement route and the current position of the infant according to pressure signals sensed by different sensors at different time points, judge the movement trend of the infant according to the movement route and the current position, and control the air valve of the pneumatic software in the corresponding direction to be opened according to the movement trend.
For example, referring to fig. 2, when the pressure sensor 50 receives a pressure signal at time t1, and when the pressure sensor 60 receives another pressure signal at time t2 after several seconds, the general movement route L1 of the baby can be obtained, the controller can determine a possible movement route L2 (there are other possible routes, not shown) of the baby according to the movement route and the current position of the baby, and at this time, the controller can control the air valve of the pneumatic software 70 to open, and at this time, the pneumatic software 70 can start to swing under the inflation action of the first, second, or third air pumps, so as to attract the attention of the baby, and can also guide the baby to climb to this direction, train the climbing ability, or achieve the effect of other sensory system training.
In other embodiments, the cushion device may further include at least one inflatable support, such as a portal-type support. The inflatable stent may be disposed on the flexible cover or, in embodiments without a flexible cover, directly on the balloon, such as by sewing the ends of the stent to the balloon.
