Detailed Description

The invention is described in detail below by way of example with reference to the accompanying drawings.

The invention provides a pushing device for a snore stopping mattress, which comprises a controller and a pushing mechanism. The pushing mechanism comprises a pushing rod, a transmission mechanism and power equipment which are connected in sequence; the power equipment is connected with the ejector rod through a transmission mechanism and used for controlling the ejector rod to eject. As shown in fig. 1, the push rods are distributed in the area where the scapula is located when a human body lies on the mattress, namely an action area 1; the number 2 in the figure is the push rod position, and the circle is a channel on the mattress 3 for extending the push rod. The controller (not shown in the figure) is connected with the power equipment, and generates a control command according to an external signal to control the jacking height, the action speed and the action mode of the jacking rod. The pushing rod is integrated with a pressure sensor, and the controller identifies pushing strength and whether a user is triggered to turn over or not according to a pressure value acquired by the pressure sensor.

Referring to fig. 2, the stimulation mode of the ejector pin is the ejection mode. The push rod 5 moves upward from below the mattress to push against the body lying on the mattress 3. The cross-sectional shape of the action head 4 at the top end of the ejector rod 5 can be designed into a circle or a polygon according to actual requirements of a mattress or a bedstead structure and the like, and the action head can be designed into a circle or a polygon by taking enough jacking force as a target, the motion of the ejector rod is mainly vertical to the up-and-down motion of the mattress plane, power equipment for driving the ejector rod can be a motor or an air compressor and the like, and through testing, the motor with a proper model is simpler in operation compared with a press machine, and is more convenient to adjust, maintain and repair, better in speed, better in noise and other aspects, and simpler in control. This mode of action requires that the mattress above the ejector pin should not be too thick, not more than 50mm, otherwise the effect is significantly reduced.

The distribution area of the push rod on the mattress is the scapula area when the human body lies on the back on the bed. When lying, the main position of putting forth effort of people's health is head, shoulder blade, three positions of buttock, through experimental verification, compare in the buttock, the shoulder blade position does not have too much muscle and adipose tissue, it is comparatively sensitive to the amazing reflection of push rod, compare in the head, push rod's stimulation is comparatively soft again, be unlikely to wake up the user at once, and compare in other positions of health, like the waist, shoulder blade is as main position of putting forth effort, difficult through reducing the stimulation of bringing the discomfort of human body by push rod except with standing up, so, shoulder blade place area is the zone of action. The main distribution area is 3 centimeters above and below the scapula, and the distribution area can be expanded to 5 centimeters above and below the scapula in consideration of different physiques and heights of people. Independent push rods are uniformly distributed at intervals in the width direction of the distribution area, the distribution interval is not limited, but the distribution interval is not more than 100mm, and generally 60 mm-120 mm can be selected; otherwise the effect will be diminished or even no effect will be obtained. The number of the ejector rods can be set to be multiple according to the width of the bed, and the ejector rods can be selected to be accurate to the body no matter which position of the user in the width direction of the bed lies horizontally.

In order to realize the detection of the turning-over action, the ejector rod can be integrated with a pressure sensor. The pressure sensor is positioned at the top end of the ejector rod, is used for pushing against a human body, can be manufactured on an acting head at the top of the ejector rod, and is manufactured into a whole with the ejector rod. In view of the detection effect accompanying the action head, the action head and the ejector pin are most suitably provided as separate two parts.

The hardness of the action head cannot be too hard or too soft, and in consideration of two aspects, firstly, in the jacking process of the jacking rod and before the jacking rod keeps in a jacking state and is not turned over, along with jacking of the jacking rod, the acting force at a contact part can be gradually increased, the corresponding pressure intensity can be increased, if the action head is too soft, stimulation to a user is too weak or cannot be stimulated, and if the action head is too hard, the pressure intensity at the contact part is too high because the jacking rod is applied to the human body by the gravity of the user, or the action head is just jacked on a sensitive part such as a connection part of a scapula and muscles, and the like, so that the human body is easily injured; secondly, when the person turns over and the ejector rod cannot descend to a position low enough, the person turns over again and returns to the position before turning over, and the injury is easily caused. Therefore, tests show that the hardness of the action head is preferably 15 Shore hardness for general people, and can be adjusted to 10-20 according to the physique of different people. Moreover, the ejector rod with the detection function has a feasible structure that the sheet type pressure-sensitive sensor is attached to the action head and is connected into a whole, the action head not only plays a role in pressure monitoring and real-time feedback, and reflects action strength, but also can be matched with the control unit to control the action strength, so that the action strength is actively adjusted.

The controller is used for controlling the action strength, the action speed and the action mode of the ejector rod. The action modes comprise two modes, one mode is a repeated ejection mode, and the other mode is an ejection holding mode.

The action strength relates to the action pressure of the ejector rod contacting with a human body and the ejection height of the ejector rod. The action pressure is a main evaluation index of the action strength. The jacking height of the jacking rod is measured based on the highest position of the jacking rod when a human body does not have obvious feeling on the jacking rod when the human body lies flat, the jacking heights are different due to different suitable jacking heights of people with different physiques, an initial jacking height of 50mm is set, and then the jacking rod is manually or automatically controlled to enable a user to feel more suitable stimulation to turn over the body, but the jacking height is controlled to be between 30mm and 60mm as much as possible. When the ejector rod is ejected to a certain height, the back of a person can be slightly suspended, the contact position and the area of the human body and the bed are changed, the sleeping feeling of the person is affected, and the pressure of the contact position of the person and the ejector rod can be increased along with the increase of the ejection height. The physical constitution of people is different, including the weight and the body fat rate, so that the sensitivity of people to the same pressure is different, and people with low body fat rate are sensitive, so the action pressure cannot be taken as the only index, and the action pressure should be comprehensively considered by combining the jacking height of the jacking rod, and finally, the action pressure should be in accordance with the comfortable degree felt by people and the reflection of action intensity.

The action speed and the action mode aim at stimulating the user to turn over, and the two main modes are as follows.

The first mode is as follows: repeated pushing mode

The method comprises the following steps: the ejector pin rises and falls repeatedly, and the lift process does not have the interval. The rising speed of the ejector rod is not easy to be too fast, otherwise too sharp stimulation can cause the user in the sleeping state to be awakened suddenly, if too slow, the user does not respond to the stimulation, and experiments show that if the ejector rod rises at a speed of 20mm per minute, the user is at a proper speed, and the speed during falling is proper in a range of 20mm to 100mm per minute, and can be properly accelerated, but the condition that the sleeping is influenced by noise and the like should not be generated.

FIG. 3 is a method for controlling the pushing apparatus in the repeated pushing mode. As shown, it includes the following steps:

step 1, an initial jacking height A of repeated action is preset and can be set to be 50 mm.

Step 2, the controller receives the number of the push rod to be controlled currently, and controls the corresponding push rod to ascend and descend repeatedly; if the user has the turning-over action after repeatedly acting for 3 to 5 times, the initial jacking height A is confirmed to be proper; if the user has the turning-over action after repeatedly acting for more than 5 times, the initial jacking height A is increased by 5 mm; if the user has turned over less than 3 iterations, the initial jacking height A is lowered by 5 mm. Wherein, the push-out rod is determined by other systems according to the supine position of the human body.

And 3, in the next pushing control, controlling the pushing rod by adopting a new jacking height A, and executing the step 2.

And a second mode: jacking holding mode

The method comprises the following steps: and controlling the ejector rod to directly reach the set lifting height and then keeping for a period of time. The rising and falling speeds of the ejector pin are the same as those of the first mode. The jacking height of the jacking rod is set to be 50mm initially, and the jacking rod is kept at the jacking height for a period of time, wherein the keeping time can be 30 s; people with different physiques are suitable for different jacking heights, and the jacking height and the acting pressure can be manually or automatically adjusted.

FIG. 4 is a method for controlling the pushing apparatus in the repeated pushing mode. As shown, it includes the following steps:

step 1, presetting an initial jacking height A; and may be set to 50mm as well.

And 2, receiving the number of the push-up rod required to be controlled currently by the controller, controlling the corresponding push-up rod to rise to a height A, keeping the push-up height of the push-up rod at A for 30s, judging the turning state of a user, determining that the current push-up height A is too high if the user does not reach the push-up height A or has turning action within 5s when the push-up height A is reached, withdrawing the push-up rod, updating the push-up height A to a current value and descending by 5mm, controlling the push-up rod to continuously rise by 5mm if ② reaches 30s and the user does not have turning action, repeatedly executing the step of judging the turning state of the user at a new push-up height for 30s until the user takes action, withdrawing the push-up rod, and if the push-up height A is kept within 5s to 30s, properly turning over the current push-up height A and withdrawing the push-up rod.

When operating in either of the two modes, the selected ejector pin actuation strength, including the ejection height a' and the actuation pressure P, may be further recorded. After a plurality of times of information data collection, the proper action intensity can be selected, the jacking height is controlled on the basis of the recorded action pressure P, and if the error between the jacking height A ' corresponding to the action pressure P and the recorded jacking height A ' exceeds +/-10 mm, the recorded jacking height A ' is used as the basis, and the extending height of the jacking rod is controlled.

In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. For example, the ejector rod may not lift perpendicular to the bed surface, but set a lifting angle, where the ejector rod in the middle of the bed lifts vertically, and the closer to the bed edge, the larger the inclination angle of the ejector rod to the center of the bed. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
