Technical Field

[0001] The utility model relates to the technical field of pillows, and particularly relates to a sleep pillow. Background Art

[0002] The current pillows cannot individually adjust the height of each area of the pillow, and cannot adjust the height of each area of the pillow according to the placement of the pillow and the usage needs of consumers. Therefore, there are limitations in use. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a sleep pillow, which overcomes the above defects and can individually adjust the height of each area of the pillow.

[0004] To achieve the above purpose, the solution of the utility model is as follows:

[0005] A sleep pillow includes an outer cover, air bags, an inflation device and a deflation device. The outer cover is made of flexible material and has a central supine area at the middle position and a left side-sleeping area and a right side-sleeping area on the left and right sides of the central supine area. The three air bags are arranged in the outer cover and respectively correspond to the central supine area, the left side-sleeping area and the right side-sleeping area of the outer cover, and each air bag is independent of each other. The inflation device is used to inflate all the air bags simultaneously to make each air bag bulge, so as to support the corresponding area of the outer cover. A deflation device is individually connected to each air bag, and each deflation device is used to deflate the corresponding air bag to adjust the height of the bulge of each air bag, so as to adjust the height of the area of the outer cover corresponding to each air bag.

[0006] Further, the inflation device includes a pipeline and an inflation component. One end of the pipeline is connected to the inflation component, and the other end of the pipeline bifurcates into three sub-pipelines. Each sub-pipeline is connected to an air bag to simultaneously inflate the three air bags through the inflation component, so that the three air bags bulge simultaneously.

[0007] Further, the inflation component is a manual air pump or an electric air pump.

[0008] Further, a one-way check valve is arranged in the middle of each sub-pipeline connecting each air bag, and each one-way check valve is used to block the reverse flow of the gas in each air bag.

[0009] Furthermore, the one-way check valve includes a valve housing and a silicone plug, the valve housing having a valve cavity, the valve cavity having an air inlet end and an air outlet end, the air inlet end being connected to the inflation component, and the air outlet end being connected to the air bag, the silicone plug being a hollow structure, one end of which has an opening, and the other end of which extends away from the opening and obliquely toward the center of the silicone plug to form an oblique wedge-shaped cavity bottom, the opening of the silicone plug is sealed and connected to the air inlet end to separate the valve cavity into an inner cavity and an outer cavity, the inner cavity being connected to the air inlet end, and the outer cavity being connected to the air outlet end, and a valve is provided at the cavity bottom of the silicone plug, the valve being used to connect or isolate the inner cavity and the outer cavity.

[0010] Furthermore, the bottom of the silicone plug is elastic, and the size of the valve gradually decreases from the side close to the opening to the side away from the opening. When the air pressure in the inner cavity is greater than that in the outer cavity, the valve opens, and the gas flows from the inner cavity into the outer cavity. When the air pressure in the outer cavity is greater than that in the inner cavity, the air pressure in the outer cavity generates pressure on the bottom of the silicone plug to close the valve.

[0011] Furthermore, the deflation device is a deflation button, which includes a cavity shell and a button. The cavity shell has a cavity, the cavity has an air inlet and an air outlet, the air inlet is connected to the air bag, and the air outlet is connected to the outside world. The button is set in the air outlet and is used to either press to open or loosen the air outlet.

[0012] The cam is pressed against the push rod and the push rod is pressed against the push rod, and the push rod is pressed against the push rod, so that the push rod is pressed against the push rod and the push rod is pressed against the push rod.

[0013] Furthermore, the three air bags are all annular air bags, so that when inflated, the outer periphery of the air bag bulges, and after inflation, the middle of the air bag is concave.

[0014] After adopting the above solution, the beneficial effects of the utility model are:

[0015] In the present utility model, the outer cover is made of a flexible material, which has a central supine area at the middle position and a left-side sleeping area and a right-side sleeping area on the left and right sides of the central supine area. The three air bags are arranged in the outer cover and respectively correspond to the central supine area, the left-side sleeping area and the right-side sleeping area of the outer cover, and the air bags are independent of each other. The inflation device is used to inflate all the air bags simultaneously to make the air bags bulge so as to support the corresponding area of the outer cover. A deflation device is individually connected to each air bag, and each deflation device is used to deflate the corresponding air bag to adjust the height of the bulge of each air bag, so as to adjust the height of the area of the outer cover corresponding to each air bag. Therefore, the present utility model can individually adjust the height of each area of the pillow to make the height of each area of the pillow appropriate and meet different usage requirements of consumers.

Detailed Embodiment

[0022] The following will make a detailed description of the present utility model in conjunction with the drawings and specific embodiments.

[0023] As Figures 1 to 5 shown, the present utility model provides a sleep pillow, including an outer cover 10, an air bag 20, an inflation device 30 and a deflation device 40;

[0024] Among them, the outer cover 10 is made of a flexible material, which has a central supine area at the middle position and a left-side sleeping area and a right-side sleeping area on the left and right sides of the central supine area. The three air bags 20 are arranged in the outer cover 10 and respectively correspond to the central supine area, the left-side sleeping area and the right-side sleeping area of the outer cover 10, and the air bags 20 are independent of each other to keep each air bag 20 pressurized. The inflation device 30 is used to inflate all the air bags 20 simultaneously, so that each air bag 20 bulges to support the corresponding area of the outer cover 10. A deflation device 40 is individually connected to each air bag 20, and each deflation device 40 is used to deflate the corresponding air bag 20 to adjust the height of the bulge of each air bag 20, so as to adjust the height of the area of the outer cover 10 corresponding to each air bag 20, making the height of the area of the outer cover 10 corresponding to each air bag 20 appropriate; specifically, the outer cover 10 is divided into an upper outer cover 11 and a lower outer cover 12. The upper outer cover 11 is concave to form an upper groove, and the lower outer cover 12 is concave to form a lower groove, so as to form a placement cavity for wrapping the air bag 20 inside the outer cover 10 when the upper outer cover 11 and the lower outer cover 12 are combined. The placement cavity is used to prevent the air bag 20 from shifting and can also protect the air bag 20. Preferably, the outer cover 10 is made of sponge;

[0025] Specifically, in the state where the air bag 20 bulges, each air bag 20 is deflated through each deflation device 40 respectively, so as to reduce the height of the bulge of each air bag 20. Moreover, the longer the deflation time is, the less gas remains in the air bag 20, and the lower the height of the bulge of the air bag 20 is. Therefore, by controlling the deflation time of each deflation device 40, the height of the bulge of each air bag 20 is adjusted, and then the height of the area of the outer cover 10 corresponding to each air bag 20 is adjusted;

[0026] Specifically, the three air bags 10 are all annular air bags, so that when inflated, the periphery of the air bag 10 bulges, and after inflation, the middle of the air bag 10 is concave, and the concave part is used for the human head to be placed in, so as to improve the comfort of using the present invention.

[0027] Specifically, the inflation device 30 includes a pipeline 31 and an inflation component 32. One end of the pipeline 31 is connected to the inflation component 32, and the other end of the pipeline 31 bifurcates to form three sub-pipelines 311, and each sub-pipeline 311 is connected to an air bag 20, so as to inflate the three air bags 20 simultaneously through the inflation component 32, making the three air bags 20 bulge simultaneously and also making the areas of the outer cover 10 corresponding to the three air bags 20 bulge simultaneously;

[0028] Specifically, the inflation component 32 is a manual air pump or an electric air pump for inflating the three air bags 20 simultaneously.

[0029] Furthermore, a one-way check valve 50 is provided in the middle of each sub-pipeline 311 connecting to each air bag 20. Each one-way check valve 50 is used to block the backflow of gas in each air bag 20, thereby preventing the gas in the air bag 20 from flowing into the inflatable component 32.

[0030] Specifically, the one-way check valve 50 includes a valve housing 51 and a silicone plug 52. The valve housing 51 has a valve cavity 511. The valve cavity 511 has an air inlet end 512 and an air outlet end 513. The air inlet end 512 is connected to the inflatable component 32, and the air outlet end 513 is connected to the air bag 20. The silicone plug 52 is a hollow structure, one end of which has an opening 521, and the other end of which extends away from the opening 521 and toward the center of the silicone plug 52 to form an oblique wedge-shaped cavity bottom 522. The opening 521 of the silicone plug 52 is sealed and connected to the air inlet end 51. 2, the valve chamber 511 is divided into an inner chamber 5111 and an outer chamber 5112, the inner chamber 5111 is connected to the air inlet end 512, and the outer chamber 5112 is connected to the air outlet end 513. A valve 523 is provided at the cavity bottom 522 of the silicone plug 52, and the valve 523 is used to connect or isolate the inner chamber 5111 and the outer chamber 5112. Specifically, the air bag 20 is connected to the air outlet end 513 of the valve chamber 511, thereby communicating with the outer chamber 5112, and the inflatable component 32 is connected to the air inlet end 512 of the valve chamber 511, thereby communicating with the inner chamber 5111.

[0031] Specifically, the cavity bottom 522 of the silicone plug 52 is elastic, and the size of the valve 523 gradually decreases from the side close to the opening 521 to the side away from the opening 521. When the air pressure in the inner cavity 5111 is greater than that in the outer cavity 5112, the valve 523 opens, and the gas flows from the inner cavity 5111 to the outer cavity 5112. When the air pressure in the outer cavity 5112 is greater than that in the inner cavity 5111, the air pressure in the outer cavity 5112 generates pressure on the cavity bottom 522 of the silicone plug 52, so that the valve 523 is closed. Specifically, in addition to the pressure of the air pressure of the outer cavity 5112 on the cavity bottom 522 of the silicone plug 52, which can close the valve 523, the cavity bottom 522 of the silicone plug 52 also has its own restoring force, which can close the valve 523.

[0032] Preferably, the air release device 40 is an air release button 41. The air release button 41 includes a cavity shell 411 and a button 415. There is a cavity 412 inside the cavity shell 411. The cavity 412 has an air inlet 413 and an air outlet 414. The air inlet 413 is communicated with the air bag 20, and the air outlet 414 is communicated with the outside. The button 415 is arranged in the air outlet 414 and is used to open or release the blockage of the air outlet 414 by pressing or loosening; specifically, the air bag 20 is communicated between the air release button 41 and the one-way check valve 50. When the gas in the air bag 20 is full, after the gas in the air bag 20 comes out, part of it flows towards the one-way check valve 50 and part flows towards the air release button 41. Since the air pressure in the outer cavity 5112 is greater than the air pressure in the inner cavity 5111 at this time, the valve 523 is closed, so the gas cannot flow out through the one-way check valve 50. And at this time, the air release button 41 is also closed, so the gas cannot flow out through the air release button 41 either. When the air release button 41 is pressed, the air outlet 414 is opened. At this time, the gas in the air bag 20 flows out from the air outlet 414 to the outside. The structure is simple and the air release is convenient;

[0033] Specifically, an installation seat 416 is arranged outside the cavity shell 411. The air outlet 414 is arranged in the installation seat 416. The button 415 includes a pressing part 4151 and a connecting rod 4152. One end of the connecting rod 4152 extends into the cavity 412 from the air outlet 414 and expands into a spherical shape. The other end of it is connected to the pressing part 4151. The pressing part 4151 is slidably arranged in the installation seat 416 and can move along the installation seat 416 in the direction close to or away from the air outlet 414. When moving in the direction away from the air outlet 414, it drives the connecting rod 4152 to move, so that the spherical end of the connecting rod 4152 blocks the air outlet 414. Or when moving in the direction close to the air outlet 414, it drives the connecting rod 4152 to move, so that the spherical end of the connecting rod 4152 moves away from the air outlet 414 to open the air outlet 414. An arc surface that fits the spherical end of the connecting rod 4152 is formed at the end of the air outlet 414 located inside the cavity 412. The arc surface is used for the spherical end of the connecting rod 4152 to be embedded. And a compression spring 417 is also arranged between the pressing part 4151 and the installation seat 416. The compression spring 417 is used to elastically push the pressing part 4151 outwards, so that the spherical end of the connecting rod 4152 is embedded in the arc surface to close the air outlet 414, thereby ensuring the airtightness of the blockage and being beneficial to blocking the air outlet 414 for a long time.
