Description

Technical Field

[0001] The utility model relates to a personal product, in particular to a sleeping-aiding pillow. Background Art

[0002] The hug pillow is a common item in home life, similar to a pillow. The common one is only half the size of a normal pillow. Holding it in your arms can keep you warm and provide some protection. It gives people a warm feeling and has become a common ornament for home use and decoration and a must-have item for car decoration. With the improvement of people's living standards, the hug pillow is getting closer and closer to people's lives, becoming an indispensable decoration for home life, office white-collar workers, and car decoration.

[0003] Now the pillows on the market also have more and more additional functions. For example, the breathing pillow disclosed in CN215226543 simulates breathing by driving the airbag to inflate and deflate through an air pump, so that the user's breathing can be adjusted to the same frequency as the pillow's breathing, achieving the effect of respiratory traction. In this way, the user's breathing can be slowed down, achieving the effect of helping sleep. Currently, the breathing guidance products on the market all have some built-in breathing guidance parameters. These parameters are fixed breathing parameters obtained based on some experts or tutorials, and may not be suitable for everyone. It is impossible to generate exclusive breathing guidance parameters according to different users. Utility Model Content

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "installed / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0032] refer to Figure 1-Figure 9 The present embodiment provides a breathing monitoring pillow, comprising: an outer shell 1 and an inner shell 2 arranged in the outer shell 1, an inner shell is further arranged between the outer shell 1 and the inner shell 2, the outer shell 1 and the inner shell are detachably connected, a control box 3 is arranged in the inner shell 2; a control circuit board 31 and a gyroscope chip 32 are arranged in the control box 3, and the gyroscope chip 32 is used to monitor the breathing parameters of the user when the pillow is placed on the chest or abdomen of the user. The above-mentioned breathing monitoring pillow is provided with a gyroscope chip 32. When the pillow is placed against the abdomen or chest of the human body, the user's breathing will cause the abdomen or chest to rise and fall, thereby driving the pillow to rise and fall. The acceleration of the gyroscope chip 32 is used to capture the change cycle of the rising and falling motion, so as to monitor the breathing parameters of the user. In addition, the position where the gyroscope chip 32 is arranged is such that when the user uses the pillow normally, the position where the gyroscope chip 32 is located corresponds to the abdomen or chest of the user. The abdomen or chest moves most obviously when the human body is breathing at rest, so placing the control circuit board 31 and the gyroscope chip 32 in this way can obtain more accurate breathing parameters.

[0033] The above-mentioned pillow can monitor the user's breathing in real time, and by setting a storage unit on the control circuit board 31, the storage unit is connected to the gyroscope chip 32 to store the breathing parameters monitored by the gyroscope chip 32. After a period of recording, the user's normal breathing rhythm during wakefulness / sleep can be summarized. Then, according to the user's current breathing state, match the appropriate breathing frequency and breathing ratio parameters; for example, when the device detects that the user's breathing rhythm becomes faster, the pillow will automatically match the parameters, and in the first stage guide the user to the normal breathing state, and then slowly guide the user to the breathing rhythm during sleep.

[0034] In order to achieve breathing guidance, a control unit is also provided on the circuit board, and the control unit is used to output a control signal to control the air pump 34 and the solenoid valve 33 provided in the control box 3 to perform inflation and deflation actions; for this purpose, the pillow also includes a deformation element, specifically an air bag 35; the air bag 35 is connected to the solenoid valve 33 through a first air pipe 36, and the solenoid valve 33 is connected to the air pump 34 through a second air pipe 37. By controlling the inflation and deflation frequency of the air bag 35, the user's breathing can be guided, so as to match the appropriate breathing frequency and breathing ratio parameters according to the user's current breathing rhythm.

[0035] In this embodiment, the airbag 35 is exposed on the upper surface of the control box 3. Since the inner liner 2 is made of soft material, the airbag 35 will squeeze the inner liner 2 during the inflation and deflation process to drive the inner liner 2 up and down. As long as the user places his hand on the side that is facing away from the abdomen, he can clearly feel the inflation and deflation of the airbag 35, and then adjust his own breathing frequency with the inflation and deflation frequency of the airbag 35. By arranging the airbag 35 on the upper surface of the control box 3, it can be avoided that the airbag 35 interferes with the user's breathing monitoring parameters when working.

[0036] In order to place the control box 3, the inner liner 2 is divided into an inner liner upper mold 21 and an inner liner lower mold 22, and the inner liner upper mold 21 and the inner liner lower mold 22 are assembled to form a chamber for accommodating the control box 3. The control box 3 is embedded between the inner liner upper mold 21 and the inner liner lower mold 22, and then the inner outer shell 1 is used to fix the inner liner 2 inside the outer shell 1, so as to avoid displacement of the control box 3 in the pillow and affect the accuracy of monitoring.

[0037] The above-mentioned pillow can realize monitoring the breathing parameters of the user, and match the appropriate breathing frequency and breathing ratio parameters for breathing guidance. However, the breathing frequency and breathing ratio parameters used for matching are often fixed breathing parameters obtained according to some experts or tutorials, but these breathing parameters are not necessarily suitable for everyone. Therefore, it is also necessary to perform Fourier transformation on the user's breathing parameters collected by the gyroscope chip 32, and obtain the average number of breaths and the ratio of exhalation to inhalation of the user in one minute according to Tinhalation and Texhalation, and then combine the research results of Jenni fer et al. of the University of Michigan in the United States: during the sleep stage of the sleeper, people's average heart rate / respiratory rate will decrease by 20%, so as to induce according to the breathing state monitored by the user, so that the user can go from nervous → calm → to sleep, and simulate the change curve from wakefulness to sleep through background data analysis, or according to the parameters preset by the user in advance, in combination with the collected change curve, so as to automatically induce the breathing from the current breathing situation of the user to the breathing during sleep, and the control circuit board 31 transmits the induced parameter change signal to the air pump 34 and the electromagnetic valve 33, so that the airbag 35 is filled and deflated according to the induced curve change parameter. Since the above process generates matching breathing frequency and breathing ratio parameters based on the collected user breathing parameters, it is optimized for different users to meet the usage needs of various users.

[0038] In this embodiment, the gyroscope chip 32 is attached to the center of the short side of the circuit board, and the X-axis and Y-axis of the gyroscope chip 32 are respectively parallel to the short side X and the long side Y of the circuit board. When the central axis of the circuit board is parallel or consistent with the central axis of the pillow, the x-axis and Y-axis of the gyroscope chip are respectively parallel to the two sides of the circuit board, which can ensure that the x-axis and the y-axis are pointing to the position of the central axis of the pillow. In this way, when the abdomen or chest rises and falls, the data change of the x-axis or y-axis is most obvious, and the data change of the x-axis or y-axis will form a waveform graph. The change frequency of the waveform graph is roughly consistent with the breathing frequency, which can be used to characterize the breathing frequency or calculate the time for the waveform to change from the highest peak to the lowest value, and the time for the lowest value to change to the highest value, and the ratio of these two times is used to characterize the breathing ratio.

[0039] The pillow in this embodiment includes a head and a tail arranged opposite to the head. Specifically, the pillow is arranged in the shape of a bear, and the area of ​​the head is smaller than the area of ​​the tail. The gyroscope is arranged in the tail, wherein the direction of the X-axis or Y-axis of the gyroscope is arranged to point to the head. The area of ​​the head of the pillow is smaller than the area of ​​the tail, which conforms to the user's habit of using the pillow. The head is lighter and faces upwards close to the user's heart, so that the tail can be naturally placed in the user's abdomen or chest. If the head is too heavy or the area is too large and close to the heart, the user will feel uncomfortable due to the excessive load. The x-axis or y-axis of the gyroscope is arranged to point to the head position of the pillow, so that when the gyroscope follows the movement of the user's abdomen, the axis pointing to the head will have the most obvious data change, while the data changes of the other two axes are not obvious. Therefore, if the x-axis or y-axis of the gyroscope is not arranged toward the user's head, the data change effects of the three axes are not obvious, and the effect of monitoring breathing will be greatly reduced. As a simple replacement of this embodiment, the pillow can also be arranged in other shapes, as long as the area of ​​the head is smaller than the area of ​​the tail.

[0040] Furthermore, the airbag 35 is arranged in the Z-axis direction of the gyroscope, and the projection area of ​​the deformable element in the Z-axis direction covers the gyroscope. This ensures that the gyroscope can monitor breathing, and the airbag 35 can guide the user's breathing according to the breathing data of the gyroscope.

[0041] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
