Detailed Description

Example 1: referring to fig. 1 and 4, the pillow core is wrapped by a soft air bag [1] and a pillow case [2] made of soft materials such as cloth and sponge, one end of a conduit [5] is connected with the air bag [1], and the other end is communicated with a high-pressure air storage tank or an air compressor [3] which can be inflated manually or electrically through a pressure regulating valve [4], as shown in fig. 1. The height adjusting device of the height self-adjusting pillow consists of a pressure adjusting valve [4] and a high-pressure air storage tank or an air compressor [3], and is mainly designed by utilizing the principle that the weight of the head of a human body is basically kept in a stable range no matter the head of the human body lies on the back or on the side when the neck of the human body is in a completely relaxed state, namely the pressure of the head of the human body on the pillow is basically stable. The pressure regulating valve [4] can adopt the pressure regulating valve shown in fig. 4, and consists of an adjusting screw rod [8], an adjusting nut [9], a compression spring [10], an air cylinder [25], a valve body [11], a sealing ring [12], an exhaust hole [13], an air inlet [14], a sealing gasket [15], a compression spring [16], an air inlet switch [17] and a conduit [5] communicated with an air bag. When the height self-adjusting pillow is used, the adjusting screw rod [8] is adjusted to a proper position according to the weight of the head of a person and the sleeping habit, then the high-pressure air storage tank or the air compressor [3] is opened or started, so that the soft air bag [1] is filled with compressed air with the pressure allowed by the pressure regulating valve [4], and the height self-adjusting pillow is in a full filling state. When a person sleeps on the side, the distance between the head of the person and the bed surface is larger, the height of the height self-adjusting pillow is just at the height or slightly higher than the height, the weight of the head of the person is transferred to the pillow after the head of the person is placed on the pillow, and at the moment, because the soft air bag [1] of the height self-adjusting pillow has air with proper pressure, the height of the height self-adjusting pillow keeps unchanged or slightly reduces and then can completely or basically bear the weight of the head of the person, so that the neck of the person is in a completely relaxed state; when a human body is changed from lying on side to lying on back, the distance between the head of the human body and the bed surface is reduced, the height of the height self-adjusting pillow in the filling state is obviously higher than the proper height when lying on back, when the head of the human body is placed on the pillow, the neck of the human body cannot be in a complete relaxing state, muscles on the back of the neck are in a stretching state, the head transmits pressure larger than the weight of the head to the height self-adjusting pillow, so that the pressure of the soft air bag [1] is increased, the valve body [11] of the pressure regulating valve [4] pushes the spring [10] to compress and opens the exhaust hole [13] to release the pressure so as to reduce the height of the pillow until the pressure of the soft air bag [1] returns to a preset value, the pressure release is stopped, and at the moment, the spring; when a human body lies on the back to lie on the side, the distance between the head of the human body and the bed surface is increased, the height of the height self-adjusting pillow in a compressed state is obviously smaller than the proper height when the human body lies on the side, when the head of the human body is placed on the pillow, the neck of the human body cannot be in a completely relaxed state, muscles on the upper side of the neck are in a stretched state, the pressure transmitted by the head to the height self-adjusting pillow is smaller than the weight of the head, so that the pressure of the soft air bag [1] is reduced, the spring [10] of the pressure regulating valve [4] pushes the valve body [11] to move and pushes the compression spring [16] of the air inlet switch [17] to compress to open the air inlet hole [14], high-pressure air in the high-pressure air storage tank or the air compressor [3] enters the soft air bag [1] to increase the height of the pillow until the pressure of the soft air bag [, the height adjustment work of the height self-adjusting pillow is completed.

Referring to fig. 5, in this embodiment, the pressure regulating valve [4] can be the one shown in fig. 5, which is formed by processing the valve body [11] into a hollow body, processing the vent hole [19] on the side wall, processing the vent hole [18] on the lower end, omitting the air inlet switch [17] and the compression spring [16], pushing the valve body [11] to move by the air pressure in the pressure regulating valve [4] and the spring [10], communicating the vent hole [19] with one of the air inlet hole [14] and the air outlet hole [13] to adjust the pressure in the soft air bag [1] to adjust the height of the pillow, or not communicating the vent hole and keeping the pressure or the height in the soft air bag [1 ].

Referring to fig. 6, in this embodiment, the pressure regulating valve [4] shown in fig. 6 can be used, in which the valve body [11] is replaced by a soft membrane [21] and a hard plate [20] capable of adhering to the soft membrane [21], a pressure relief switch [22] is added in the valve cavity [25], and at this time, the air inlet switch [17] and the pressure relief switch [22] are both preferably made of elastic material or provided with elastic devices, and preferably have a certain movement gap with the hard plate [20 ]. When the pressure in the soft air bag [1] is reduced, the spring [10] pushes the hard sheet [20] to press down to open the air inlet switch [17] for pressurization, and when the pressure in the soft air bag [1] is increased, the hard sheet [20] pushes the spring [10] to move upwards and open the pressure relief switch [22] for pressure relief.

Referring to fig. 2, in this embodiment, the two or more layers of soft air bags [1] can be overlapped to form the pillow core of the pillow, and the soft air bags are arranged in different directions to improve the stability of the pillow.

Referring to fig. 13, in this embodiment, the pillow is assembled by two or more sets of soft air bags [1] and pressure regulating valves [4], and a load bearing plate with good load bearing capacity is added between the pillow case [2] and the soft air bags [1], so that the load bearing plate transfers the weight of the head of the human body to each soft air bag [1], as shown in fig. 13; in this case, the conduits [5] of the respective soft air bags [1] may be connected to each other to share the pressure regulating valve [4 ].

Example 2: referring to fig. 3, 7 and 8, the pillow is assembled by two or more groups of soft air bags [1] and pressure regulating valves [4] on the basis of the embodiment 1, and one or more groups of soft sensing air bags [7] are added on the upper surface of each group of soft air bags [1] to be communicated with the gas pressure sensor [23] on the pressure regulating valves [4], as shown in fig. 3; the pressure of each group of soft air bags [1] is determined by controlling the communication between each vent hole [24] and each conduit [5] by a gas pressure sensor [23], as shown in figure 7; the gas pressure sensor [23] consists of a compression spring [10], a cylinder [25], a piston [26], a vent hole [24], an air inlet [5], a sealing gasket [15], an air inlet switch [17], a soft film [21], a hard sheet [20] capable of being attached to the soft film [21] and a conduit [6], and is shown in figure 8; when the soft sensing air bag [7] is pressed by the head of a human body, the pressure of the soft sensing air bag [7] is increased, the piston [26] pushes the hard sheet [20] to press down to open the air inlet switch [17], so that the conduit [5] is communicated with the vent hole [24 ]; the pressure regulating valve [4] can enter a normal pressure regulating state according to different sleeping postures of the human body to regulate the pressure of the soft air bag [1] matched with the pressure regulating valve [4] so as to regulate the height of the pillow where the head of the human body is positioned as long as the pressure regulating valve [4] is provided with a vent hole [24] communicated with the conduit [5 ]; when all the soft sensing air bags [7] connected with the pressure regulating valve [4] are not pressed by the head of a human body, the pressure of the soft sensing air bags [7] is not changed, the piston [26] is not moved and can not open the air inlet switch [17] to ensure that the conduit [5] can not be communicated with the vent hole [24], and the pressure regulating valve [4] can not regulate the pressure of the soft air bag [1] matched with the pressure regulating valve and can not keep the original state. Therefore, the total air flow amount is reduced when the height of the pillow is adjusted every time, and the working efficiency and the reaction speed are improved. The gas pressure sensor [23] can be replaced by other suitable gas sensing switches or electronic sensing switches.

Example 3: referring to fig. 11 and 12, on the basis of the foregoing embodiment, one or more force-sensitive or touch-sensitive sensors [26] are installed above each group of soft sensing airbags [7] instead of the soft sensing airbags [7], signals of the force-sensitive or touch-sensitive sensors [26] on each group of soft sensing airbags [7] are connected to the input end of an electronic or gate [28] through a lead [27], and the output end of the electronic or gate [28] controls an electronic valve [31] in the pressure regulating valve [30] through a lead [29], and as shown in fig. 12, the force-sensitive or touch-sensitive sensors [26] preferably adopt digital outputs or are additionally provided with analog-digital converters at the input end of the electronic or gate [28 ]. The pressure regulating valve [30] is formed by installing an electronic valve [31] in an air inlet [5] or an air outlet [13] on the basis of the pressure regulating valve [4], as shown in figure 11. When the head of a human body presses the pillow, the pressed force-sensitive or touch-sensitive sensor [26] transmits a signal to the electronic OR gate [28], and then the electronic OR gate [28] outputs a signal to open the electronic valve [31] in the pressure regulating valve [30], so that the soft air bags [1] can normally carry out pressure, namely height adjustment according to different sleeping postures of the human body; when the force-sensitive or touch-sensitive sensor [26] of the soft air bag [1] is not pressed, the electronic OR gate [28] has no signal output, the electronic valve [31] is not opened, and the soft air bag [1] does not adjust the pressure, namely the height, and keeps the original state.

With reference to fig. 9 and 10, in this embodiment, an electronic valve [31] can be installed at the bottom of the cylinder [25] of the pressure regulating valve [30], a compression spring [32] is installed between the electronic valve [31] and the soft membrane [21] and the hard plate [20], when the force-sensitive or touch-sensitive sensor [26] is not pressed, the valve body of the electronic valve [31] is at the highest position, the compression spring [32] is compressed, the exhaust valve value of the pressure regulating valve [30] is reduced, and the soft air bag [1] is at a low pressure state; when the force-sensitive or touch-sensitive sensor [26] is pressed, the valve body of the electronic valve [31] is at the lowest position, the compression spring [32] is loosened, the exhaust valve value of the pressure regulating valve [30] is increased, and the soft air bag [1] is in a high-pressure state, as shown in fig. 9. Or the electronic valve [31] can be arranged on the adjusting screw rod [8], a compression spring [32] is arranged between the electronic valve [31] and the hard sheet [20], when the force-sensitive or touch-sensitive sensor [26] is not pressed, the valve body of the electronic valve [31] is at the highest position, the compression spring [32] is loosened, the exhaust valve value of the pressure regulating valve [30] is reduced, and the soft air bag [1] is in a low-pressure state; when the force-sensitive or touch-sensitive sensor [26] is pressed, the valve body of the electronic valve [31] is at the lowest position, the compression spring [32] is compressed, the exhaust valve value of the pressure regulating valve [30] is increased, and the soft air bag [1] is in a high-pressure state, as shown in fig. 10. And the soft air bag [1] can be in a low-pressure state when in work and in a high-pressure state when not in work, and the working mode of the electronic valve [31] is only required to be changed.

Example 4: with reference to fig. 14, it is based on the above embodiment, and is formed by assembling two or more sets of soft air bags [1] and pressure regulating valves [30] and installing force-sensitive or touch-sensitive sensors [26] on the pillow with a bearing plate added between the pillow case [2] and the soft air bags [1], transmitting the signals of the force-sensitive or touch-sensitive sensors [26] between two adjacent soft air bags [1] to the same electronic or gate [28], adding a secondary electronic or gate [45] between the electronic or gate [28] and the pressure regulating valves [30], simultaneously transmitting the output signals of the electronic or gate [28] to the adjacent secondary electronic or gate [45], transmitting the signals of the force-sensitive or touch-sensitive sensors [26] right above the soft air bags [1] to the corresponding and adjacent secondary electronic or gate [45], as shown in fig. 14. When the head is pressed between the two adjacent soft air bags [1], the two adjacent soft air bags [1] normally adjust the pressure, namely the height according to different sleeping postures of the human body, and the rest of the soft air bags keep the original state; when the head is pressed right above the middle soft air bag [1], the adjacent three groups of soft air bags [1] normally adjust the pressure, namely the height according to different sleeping postures of the human body, and the rest are kept unchanged.

With reference to fig. 15, in the present embodiment, the position of the valve body may be adjusted by a valve body mounting position adjusting device of the electronic valve [31] in the pressure regulating valve [30] shown in fig. 9 and 10, or the electronic valve [31] in the pressure regulating valve [30] shown in fig. 9 and 10 may be omitted, and a position adjusting mechanism may be mounted between the adjusting screw [8] and the valve body of the pressure regulating valve [30] to adjust the position of the adjusting screw [8] and thus the threshold value of the pressure regulating valve [30 ]; a central processing unit [33] is added between the electronic OR gate [28] and the pressure regulating valve [30], and the central processing unit [33] comprises a mechanical calculator, an analog-digital converter, a digital-analog converter, a position judger of a force-sensitive or touch-sensitive sensor [26], a data processing center, a memory, an auxiliary circuit and the like.

With reference to fig. 16, in this embodiment, the electronic or gates [28] and [45] can be directly integrated into the central processing unit [33], the central processing unit [33] performs analysis and calculation according to signals transmitted from the force-sensitive or touch-sensitive sensors [26] to determine whether each soft air bag [1] works or bears pressure, and converts the analysis and calculation results into digital or analog signals to be transmitted to each electronic valve [31] to adjust the pressure of each soft air bag [1 ]. Or the electronic valve [31] in the pressure regulating valve [30] shown in the figures 9 and 10 can be modified into a position adjusting device to adjust the compression state of the compression spring [32] or adjust the position of the adjusting screw [8], the signal of each force-sensitive or touch-sensitive sensor [26] is transmitted to the central processing unit [33], the central processing unit [33] analyzes and calculates the working pressure of each soft air bag [1] according to the signal transmitted by each force-sensitive or touch-sensitive sensor [26], and converts the analysis and calculation result into a digital or analog signal to be transmitted to each position adjusting device to adjust the compression state of the compression spring [32] or adjust the position of the adjusting screw [8], so that each compression spring is in a proper compression state, and each pressure regulating valve [30] adjusts the pressure of each air bag soft air bag [1] according to the signal of the central processing unit [33] to keep the pillow in a balanced state all the time, ensure comfortable sleep.

At the moment, the weight of the head of the human body in a completely relaxed state of the neck can be stored in the central processing unit [33], the central processing unit [33] compares the data transmitted from the central processing unit [35] with the weight of the head of the human body in the storage, and when the data transmitted from the central processing unit [35] is larger than the weight of the head of the human body stored in the central processing unit [33] or is larger than or exceeds a certain range, the central processing unit [33] sends an instruction to reduce the threshold value of the pressure regulating valve [30] so as to reduce the pressure of the soft air bag [1 ]; when the data transmitted from the central processor [35] is smaller than the weight of the head of the human body stored in the central processor [33] or is smaller than and exceeds a certain range, the central processor [33] sends an instruction to increase the threshold value of the pressure regulating valve [30] so as to increase the pressure of the soft air bag [1 ]. In the embodiment, the central processing unit [35] and the central processing unit [33] can be combined together to improve the integration level of the circuit.
