Description

Technical Field

[0001] This utility model relates to the field of household goods technology, and in particular to an adjustable height airbag pillow. Background Technology

[0002] In modern life, the comfort of pillow height directly affects sleep quality. Traditional pillows often use materials such as sponge and down for fixed filling structures, which cannot dynamically adjust the height according to the user's body shape, sleeping posture, or cervical spine health needs. This leads to users having to frequently change pillows or facing problems with insufficient cervical spine support. As a result, pillows with air bladders have been introduced. The air bladders inside the pillow can be inflated, thus greatly satisfying the user's body shape and sleeping posture.

[0003] However, some existing airbag pillows adjust height by inflating airbags, but they generally have the following drawbacks: the adjustment precision of a single airbag is insufficient, and with only a single airbag, it is impossible to distinguish the different support needs of the head and neck, which can easily lead to the neck being unsupported or the head tilting back excessively. In addition, the air pressure adjustment precision inside the airbag is relatively limited, making it difficult to meet the needs of users who require more precise support for pillow height, resulting in a poor user experience.

[0004] Therefore, an adjustable height airbag pillow is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable height airbag pillow, which can solve the following defects of existing airbag pillows, which adjust the height by inflating the airbag: the adjustment precision of a single airbag is insufficient; with only a single airbag, it is impossible to distinguish the different support needs of the head and neck, which can easily lead to the neck being unsupported or the head tilting back excessively; and the adjustment precision of the air pressure inside the airbag is relatively limited, which makes it difficult to meet the needs of users who require more precise support for the pillow height, resulting in a poor user experience.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable height airbag pillow, comprising a pillow body and a screen display air pump, wherein an airbag assembly is provided inside the pillow body, and the pillow body is filled with latex filling material, wherein the latex filling material is provided with support layers of different densities corresponding to the head, neck and other areas, and the air supply end of the screen display air pump is connected to an air supply hose.

[0007] The airbag assembly includes a head airbag and a neck airbag located inside the pillow body on the rear and front sides, respectively. The head airbag and neck airbag are located inside the latex filling. A check valve head is connected to the right side of each of the head airbags and neck airbags. The right side of the check valve head passes through the latex filling and the interior of the pillow body in sequence. The right side of the rear check valve head is inserted into the left side of the air delivery hose. A press-type exhaust valve is connected to the right side of each of the head airbags and neck airbags. The right side of the press-type exhaust valve passes through the interior of the pillow body. A pressure feedback structure is provided on the right side of each of the head airbags and neck airbags.

[0008] Preferably, the pressure feedback structure includes a pressure sensor adhered to the right side of the head airbag and the neck airbag, with the sensing ends of the rear and front pressure sensors located inside the head airbag and the neck airbag, respectively.

[0009] Preferably, the front and rear sides of the right side of the pillow body are both embedded with insulated conductive connectors, which are electrically connected to the air pressure sensor.

[0010] Preferably, a power supply wire is electrically connected to the left side of the display air pump, and a power supply plug is electrically connected to the end of the power supply wire away from the display air pump. The power supply plug and the insulated conductive connector form a detachable electrical connection.

[0011] Preferably, an elastic partition layer is provided in the middle of the pillow body, the outer side of the elastic partition layer is in contact with the inner side of the latex filling, and the elastic partition layer is located between the head airbag and the neck airbag.

[0012] Preferably, the pillow body has a two-layer structure, with an inner layer of elastic breathable mesh fabric and an outer layer of elastic bamboo fiber knitted fabric.

[0013] Preferably, the rear side of the top of the pillow body is sewn with a pressure-dispersing protrusion, which is located at the top of the head airbag.

[0014] Preferably, an antibacterial and anti-mite cooling pad is sewn to the front side of the top of the pillow body. The antibacterial and anti-mite cooling pad is made of bamboo fiber fabric or breathable mesh fabric containing menthol, and the antibacterial and anti-mite cooling pad is located on top of the neck airbag.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application, by setting up an airbag assembly with independently partitioned head and neck airbags, combined with a display-enabled air pump and pressure feedback structure, allows for independent adjustment of the head and neck support height according to user needs. Specifically, the air supply hose is connected to the check valve heads of the head and neck airbags in stages. The display-enabled air pump can inflate the head and neck airbags separately. The pressure feedback structure monitors the air pressure in real time and feeds it back to the air pump, enabling it to accurately control the inflation volume according to a predetermined program. The value is displayed in real time on the display screen of the air pump. It automatically stops after reaching the preset height. When the height of the head and neck airbags needs to be lowered, the air can be quickly deflated by pressing the exhaust valve. This solves the problem that a single airbag cannot differentiate the support for the head and neck, effectively preventing the neck from being suspended or the head from tilting back excessively, and improving the targeting and accuracy of sleep support.

[0017] 2. This application fills the middle of the pillow body with latex filling material and sets support layers of different densities for the head, neck and other areas. Without affecting the normal inflation and deflation adjustment of the head airbag and neck airbag, it not only uses the elasticity of latex to buffer the stiffness of the direct support of the airbag, but also uses the zoned density design to enhance the fit to the physiological curvature of the head and cervical spine, further improving the comfort and support accuracy under different sleeping positions.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] An adjustable height airbag pillow includes a pillow body 1 and a screen display air pump 4. An airbag assembly 2 is provided inside the pillow body 1. The pillow body 1 is filled with latex filling material 3. The latex filling material 3 is provided with support layers of different densities corresponding to the head, neck and other areas. The air supply end of the screen display air pump 4 is connected to an air supply hose 5.

[0027] The airbag assembly 2 includes a head airbag 21 and a neck airbag 22 disposed inside the rear and front sides of the pillow body 1. The head airbag 21 and the neck airbag 22 are located inside the latex filling 3. A check valve head 23 is connected to the right side of both the head airbag 21 and the neck airbag 22. The right side of the check valve head 23 passes through the interior of the latex filling 3 and the pillow body 1 in sequence. The right side of the rear check valve head 23 is inserted into the left side of the air delivery hose 5. A press-type exhaust valve 24 is connected to the right side of both the head airbag 21 and the neck airbag 22. The right side of the press-type exhaust valve 24 passes through the interior of the pillow body 1. A pressure feedback structure 25 is provided on the right side of both the head airbag 21 and the neck airbag 22.

[0028] In this embodiment: By setting the airbag assembly 2, when the height of the head airbag 21 needs to be adjusted, the air delivery hose 5 of the display air pump 4 is connected to the check valve head 23 of the head airbag 21. At the same time, the power supply structure of the display air pump 4 supplies power to the pressure feedback structure 25 inside the head airbag 21. After the display air pump 4 is started, gas flows unidirectionally into the head airbag 21 through the air delivery hose 5 and the check valve head 23. At this time, the pressure feedback structure 25 monitors the air pressure inside the airbag in real time and feeds the value back to the display air pump 4. The user can preset the target air pressure value through the display screen of the display air pump 4. When the measured air pressure is close to the preset value, the display air pump 4 automatically slows down the inflation speed and stops precisely, realizing... The height of the head airbag 21 is quantitatively controlled. If the neck airbag 22 needs to be adjusted, the above insertion and inflation process can be repeated. If the height needs to be lowered, press the press-type exhaust valve 24 of the corresponding head airbag 21 and neck airbag 22 to release the gas. Flexible fine-tuning can be achieved by observing the air pressure value of the inflation pump 4 on the screen or by directly feeling the height change. The latex filling 3 inside the pillow body 1 is set with different densities according to the physiological curve of the head and neck. When the head airbag 21 and neck airbag 22 are inflated and deflated, the latex cushions the hard support of the airbag through elastic deformation. At the same time, the zoned support strengthens the fit to the curvature of the cervical spine, so that the overall curve of the pillow body 1 adapts to the human lying posture, taking into account both support accuracy and comfort.

[0029] Specifically, such as Figure 3 As shown, the pressure feedback structure 25 includes a pressure sensor 251 attached to the right side of the head airbag 21 and the neck airbag 22. The sensing ends of the pressure sensors 251 on the rear and front sides are located inside the head airbag 21 and the neck airbag 22, respectively.

[0030] Specifically, such as Figure 3 As shown, insulated conductive connectors 252 are embedded in the front and rear sides of the right side of the pillow body 1. The insulated conductive connectors 252 are electrically connected to the air pressure sensor 251.

[0031] Specifically, such as Figure 3 As shown, a power supply wire 253 is electrically connected to the left side of the display air pump 4. The end of the power supply wire 253 away from the display air pump 4 is electrically connected to a power supply plug 254. The power supply plug 254 and the insulated conductive connector 252 form a detachable electrical connection.

[0032] In this embodiment: By setting a pressure feedback structure 25, pressure sensors 251 are respectively bonded to the inner walls of the head airbag 21 and the neck airbag 22. Their sensing ends are directly exposed to the gas environment inside the airbag, and can collect air pressure data in real time and convert it into an electrical signal. When the power supply plug 254 of the display air pump 4 is inserted into the insulated conductive connector 252 on the right side of the pillow body 1, a complete power supply circuit is formed, and an RS485 differential data transmission channel is established. The pressure sensor 251 transmits the real-time air pressure value to the STM32F103 processor of the display air pump 4, and compares it with the preset air pressure threshold (which can be customized by the user through the LCD1602 display) using a PID algorithm. Yes, when the measured value approaches the target value, the processor outputs a PWM signal to adjust the micro air pump drive circuit, causing the inflation rate to linearly decrease from the initial 5L / min to 0.5L / min. When the threshold is reached, the relay power supply is immediately cut off, achieving high-precision air pressure control of ±0.5kPa. Users can monitor air pressure changes in real time through the display screen and make fine adjustments using the push-button exhaust valve 24 (exhaust rate 3L / min) to ensure that the head and neck support height meets individual needs. This closed-loop control system effectively avoids the problem of over-inflation or under-inflation of traditional airbag pillows through hardware redundancy design (dual sensor cross-calibration) and software filtering algorithm, improving adjustment accuracy and user experience.

[0033] Specifically, such as Figure 2 As shown, an elastic partition layer 6 is provided in the middle of the interior of the pillow body 1. The outer side of the elastic partition layer 6 is in contact with the inner side of the latex filling 3. The elastic partition layer 6 is located between the head airbag 21 and the neck airbag 22.

[0034] Specifically, such as Figure 2 As shown, the pillow body 1 has a two-layer structure, with an inner layer of elastic breathable mesh fabric and an outer layer of elastic bamboo fiber knitted fabric.

[0035] In this embodiment: the elastic separating layer 6 is located between the head airbag 21 and the neck airbag 22. It cushions the mutual compression of the two airbags during inflation and deflation by its own deformation, preventing positional displacement caused by air pressure changes and ensuring a smooth transition of the head and neck support interface. The elastic breathable mesh layer of the inner layer of the pillow body 1 is in close contact with the head airbag 21 and the neck airbag 22. The mesh structure quickly dissipates the heat generated by friction. The outer elastic bamboo fiber knitted fabric uses natural antibacterial properties to inhibit bacterial growth. At the same time, the high moisture absorption of bamboo fiber keeps the surface dry. The matching elastic modulus design of the two materials allows the pillow body 1 to deform synchronously during the inflation and deflation of the head airbag 21 and the neck airbag 22, which not only maintains the stability of the overall shape, but also improves the softness of the contact, achieving a balance between support and breathability.

[0036] Specifically, such as Figure 1 , Figure 5As shown, the rear side of the top of the pillow body 1 is sewn with a breathable pressure dispersion protrusion 7, which is located on the top of the head airbag 21.

[0037] Specifically, such as Figure 1 , Figure 4 As shown, an antibacterial and anti-mite cooling pad 8 is sewn onto the front side of the top of the pillow body 1. The antibacterial and anti-mite cooling pad 8 is made of bamboo fiber fabric or breathable mesh fabric containing menthol. The antibacterial and anti-mite cooling pad 8 is located on top of the neck airbag 22.

[0038] In this embodiment: By setting breathable pressure-dispersing protrusions 7 and antibacterial and anti-mite cooling pads 8, the breathable pressure-dispersing protrusions 7 are located at the top of the head airbag 21. The surface micro-protrusion structure disperses the pressure on the head, reducing local pressure and stuffiness. The antibacterial and anti-mite cooling pad 8 is made of bamboo fiber or breathable mesh fabric containing menthol. The natural bamboo quinone component inhibits bacterial growth, and the menthol microcapsules release cooling factors when in contact with the human body, which is especially suitable for summer or people who sweat a lot. The two correspond to different functional needs of the head and neck. Through the optimization of physical structure and the synergy of functional materials, the health and comfort of the sleeping area are improved.

[0039] Working Principle: When using the height-adjustable airbag pillow, the user first connects the air hose 5 of the display air pump 4 to the check valve head 23 of the head airbag 21 according to their needs. Simultaneously, the power plug 254 connects to the insulated conductive connector 252 on the right side of the pillow body 1 to power the pressure sensor 251. After starting the air pump, gas flows unidirectionally into the head airbag 21 through the check valve head 23. The pressure sensor 251, located on the inner wall of the airbag, collects the pressure data in real time, converts it into an electrical signal, and transmits it to the processor of the display air pump 4. The processor compares the measured pressure with a preset value and dynamically adjusts the inflation rate. When the pressure approaches the target value, the speed automatically slows down, and the machine stops when the threshold is reached, achieving precise height control of the head airbag 21. To adjust the height of the neck airbag 22, the above connection and inflation process is repeated. To lower the height, press the corresponding press-type exhaust valve 24 of the head airbag 21 and neck airbag 22. It can deflate quickly, and the air pressure value displayed on the screen of the air pump 4 can be flexibly adjusted. The latex filling 3 inside the pillow body 1 is set with different densities according to the physiological curve of the head and neck. When the head airbag 21 and the neck airbag 22 are inflated and deflated, the elastic deformation buffers the hard support and enhances the fit to the curvature of the cervical spine. The elastic partition layer 6 is located between the two airbags. Through its own deformation, it prevents the head airbag 21 and the neck airbag 22 from squeezing and shifting, ensuring a smooth transition of the support interface. In addition, the elastic breathable mesh layer of the inner layer of the pillow body 1 quickly dissipates the heat generated by the friction of the airbags. The outer bamboo fiber fabric keeps the surface dry with its antibacterial, anti-mite and high moisture absorption properties. The breathable pressure dispersion protrusions 7 on the top of the head airbag 21 reduce the feeling of pressure and promote air circulation. The antibacterial and anti-mite cooling pad 8 on the top of the neck airbag 22 inhibits bacterial growth and brings a cool touch. The multi-structure works together to balance the height adjustment accuracy and sleep comfort.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
