Description

Technical Field

[0001] The present invention relates to the technical field of intelligent mattresses, and in particular, to a silent air pump box and an intelligent adjustable mattress including the silent air pump box. Background Art

[0002] A person spends one-third of their life sleeping. Thus, sleep is the most basic physiological need of humans. However, according to a survey by the World Health Organization, nearly 27% of people in the world have sleep problems. Therefore, how to ensure healthy sleep is a topic of great concern.

[0003] As an important carrier for sleep, a mattress directly affects a person's sleep quality. A mattress is crucial for improving sleep quality. Traditional mattresses are mainly divided into spring mattresses, sponge mattresses, palm mattresses, latex mattresses, water mattresses, airbag mattresses, etc. A good mattress should be designed according to the weight distribution of each part of the human body and the normal curve of the spine. Among them, softness and hardness are important parameters of the mattress. A too-soft mattress causes the trunk of the human body to sag, which is not conducive to maintaining the curvature of the spine; while a too-hard mattress easily causes muscle compression and poor blood flow, resulting in an increased number of turns during sleep and the user not being able to get sufficient rest. In addition, a too-hard mattress lacks proper elasticity and cannot conform to the normal curve of the spine. Long-term use will affect the human body's posture and hinder the health of the spine. In particular, the bone development of teenagers is closely related to the mattress. A too-hard or too-soft mattress will cause poor development of the spinal vertebrae. However, the softness and hardness of the vast majority of existing mattresses on the market are fixed. For a double mattress, such as a couple, the suitable softness and hardness may not be the same for both.

[0004] Although there are currently some mattresses that can be customized with different softness and hardness on both sides to meet the different requirements of a couple for softness and hardness. For example, some airbag mattresses, the airbags on both sides can be independently inflated and deflated to achieve different softness and hardness on both sides. However, in fact, the support requirements for the mattress are also different for different trunk parts and different sleeping postures of the same person. For example, when lying flat, due to the curvature of the human spine, there is often insufficient support in the waist, and the buttocks are often the places with excessive pressure. When lying on the side, the shoulders are often the most severely compressed places. Therefore, we need a mattress that can adjust the softness and hardness of each part of the mattress in real time according to the human sleeping posture to protect the human spine, relax the muscles and promote blood circulation to achieve the healthiest sleep. Summary of the Invention

[0005] To solve the above problems, an embodiment of the present invention provides a silent air pump box for a mattress and a partitioned airbag mattress. The mattress can obtain the pressure values of each airbag through air pressure sensing according to different sleeping postures of the human body. In the mattress of the present invention, the control of the air pump and the air valve can independently inflate and deflate each airbag to achieve the purpose of adjusting the pressure of each part of the human body.

[0006] In a first aspect of an embodiment of the present invention, a silent air pump box is provided, which includes a box body, an upper cover, a support platform, an air pump, an air valve, an air pipe, sound-absorbing cotton, sound-insulating cotton, and a sound-absorbing pipe. The box body can be buckled with the upper cover to form a closed space. The support platform, the air pump, the air valve, the air pipe, the sound-absorbing cotton, the sound-insulating cotton, and the sound-absorbing pipe are all arranged in the box body. The air pump, the air valve, the air pipe, and the sound-absorbing pipe are all suspended and fixed below the support platform.

[0007] Further, an air valve flexible cushion layer is arranged between the air valve and the support platform.

[0008] Further, the sound-insulating cotton and the sound-absorbing cotton are arranged inside the box body and the upper cover from outside to inside.

[0009] Further, the air pump is suspended on the support platform through a suspension belt, and the suspension belt is a silicone belt or a rubber belt.

[0010] Further, the support platform is arranged in the box body through a plurality of support columns, and a silicone or rubber structure is adhered to the bottom of the support columns.

[0011] In a second aspect of an embodiment of the present invention, an intelligent adjustable mattress is provided. The mattress includes the above-mentioned silent air pump box and further includes an airbag layer, wherein the silent air pump box is arranged at the tail of the mattress.

[0012] Further, the airbag layer includes multi-region independently adjustable airbags and sponges. The airbags are surrounded by sponges, and the sponges surrounding the airbags are divided into sponge around the airbag, sponge in the airbag gap, and sponge in the middle of the airbag.

[0013] Further, in the airbag layer, the width of the airbags in the trunk area is smaller than the width of the airbags in the leg and head areas.

[0014] Further, air is injected into the airbag, or springs or sponges are implanted. When springs or sponges are implanted, the height of the springs or sponges is not less than half of the internal height of the airbag.

[0015] Further, the intelligent adjustable mattress further includes a pressure sensor, a data unit, and a control unit. The intelligent adjustable mattress obtains the personal sleep information and algorithm parameters of the user through pre-recording to achieve personalized parameter customization of the mattress.

[0016] The silent air pump box provided by the present invention realizes the silent design through the combination of a silicone-suspended air pump and multiple sound insulation and noise elimination devices. At the same time, the intelligent adjustable mattress provided by the present invention includes split independent adjustable airbags, truly realizing intelligent independent adjustment. Meanwhile, the personal sleep information and algorithm parameters of the user are obtained through pre-recording to complete the personalized parameter customization of the mattress.

[0029] The following will clearly and completely describe the technical solutions of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the protection scope of the present invention.

[0030] The embodiments of the present invention provide a silent air pump box 1, as Figure 1 shown. The silent air pump box 1 includes a box body 3. The silent box body 3 is mainly used to centrally place some noise - source devices together for sound insulation treatment. There is an air pipe interface 31 on the side of the box body 3, and an air pump 12, an air valve 16, an air pipe 13, a silencing pipe 15, etc. are arranged inside. A top cover 2 is arranged on the silent box body 3, and the top cover 2 and the box body 3 can be hermetically buckled. The box body 3 can be a metal box body, or a rigid box body of other materials, or a liquid. The top cover 2 can be made of metal or other rigid materials. The top cover 2 and the box body 3 are fixed by screws to form a sealed space to prevent noise from spreading to the outside through the air. The top cover 2 and the box body 3 are respectively provided with sound - insulating cotton 21 and sound - absorbing cotton (also called sound - absorbing cotton) 22 from the outside to the inside. That is, the sound - absorbing cotton 22 is in the innermost layer, and the sound - insulating cotton 21 is close to the top cover 2 and the box body 3, and the three can be bonded together. The sound - insulating air pump box 2 further includes a support platform 11 for hanging and fixing the air pump. The air pump 13 is the power source for inflating the airbag, and can be a diaphragm pump, an electromagnetic pump, an impeller pump, a piston pump, etc. In the embodiments of the present invention, one air pump 13 can be used, or multiple air pumps 13 can be connected in parallel to achieve a larger air flow rate. The embodiments of the present invention can include multiple air pumps 13, such as Figure 1As shown. The air valve 16 is used to control the inflation and deflation of a specified airbag by controlling an air pump. The intelligent mattress of the present application controls the switch of the air valve through an electrical signal to select the flow path of the air circuit. The air valve 16 can be a solenoid valve. In practical applications, the air pump and the air valve are the main sources of noise. The air pump 13, the air valve 16, the air pipe 13, and the sound-absorbing pipe 15 are all fixed on the support platform 11 through a suspension structure, and a layer of air valve flexible cushion 14 is sandwiched between the air valve 16 and the support platform 11. The main function of setting the air valve flexible cushion 14 is to weaken the vibration of the air valve 16 and prevent the vibration and sound from being transmitted to the support platform 11, so that no sound and vibration can be felt above the support platform. The material of the flexible cushion 14 can be silica gel or other materials with sound insulation properties. In the embodiment of the present invention, sound-absorbing pipes 15 are respectively inserted into the inflation and deflation paths to reduce the airflow sound during inflation of the air pump 12 and the airflow sound during deflation. In the inflation path, one end of the sound-absorbing pipe is connected to the air pump and the other end is connected to the air valve; in the deflation path, one end of the sound-absorbing pipe is connected to the deflation air valve and the other end is connected to the atmosphere..

[0031] The improvement of the silent air pump box of the present invention mainly lies in the structural design of the silent box, the silent design of the air pump, and the silent design of the air valve. The structural design of the silent box refers to concentrating the components of the noise source, such as the air pump and the air valve, in the silent box. The outer box of the silent box is made of materials with relatively high sound resistance, and the inside is made of sound insulation, sound absorption and other materials, and a sealed isolation design is adopted, which greatly attenuates the intensity of the sound. Among them, the materials with relatively high sound resistance can be solids or liquids. Solids can be metals, metal alloys, metal compounds, such as iron, aluminum, silver, copper, aluminum alloy, alumina, silica, etc. Liquids can be compounds such as water.

[0032] Regarding the silent design of the air pump, the improvement lies in minimizing the noise transmitted from the vibration of the silent box itself. The air pump can reduce the conduction of vibration by using relatively soft materials, suspension design or support design. In the preferred embodiment, a suspension design is adopted.

[0033] The silent design of the air valve in the embodiment of the present invention mainly has the following improvement points: First, a soft material is added to the bottom of the air valve to reduce the conduction of vibration. Second, through the design of the hardware circuit and program, a soft start process is added, that is, when opening and closing, by controlling the voltage, the voltage changes slowly to achieve a slow switching of the switch, thereby reducing noise. There are two methods to control the voltage to rise slowly. One is through a circuit method. For example, a low-pass filter of a resistor and a capacitor is connected to the output end where the control voltage is formed, so that the step-up voltage signal is transformed into a slowly rising voltage; the second method is through a digital-to-analog conversion module (DAC), and the output waveform is controlled by a program.

[0034] Further, two layers of materials are adhesively attached to the inner wall of the box body 3 from the inside out, namely sound insulation cotton and sound absorption cotton, to further reduce the energy of noise transmission. The main purpose of the sound absorption cotton is to absorb a part of the sound wave energy, while the sound insulation cotton increases the reflection of the sound wave and reduces the energy of penetration. Both the sound insulation cotton and the sound absorption cotton are commonly used materials. The sound insulation cotton and sound absorption cotton of the box body 3 and the sound insulation cotton and sound absorption cotton of the upper cover 2 enclose a closed space, and the sound absorption cotton layer is inside.

[0035] Figure 2 It further shows the suspension setting method of the air pump. During the operation of the air pump, it will generate micro-vibrations by itself. If the vibrations are transmitted to the entire mattress through a solid medium and then to a person's ears, it will cause relatively large noise and seriously affect sleep and rest. Figure 2 In the shown embodiment, multiple air pumps 12 are connected in parallel to increase the air flow rate, and are suspended by suspension belts 17. This suspension structure reduces the conduction of the vibrations of the air pump 12. The suspension belt 17 is preferably made of an elastic material such as silica gel or rubber. The support columns 19 and the support platform 11 build a platform for fixing the air pump 12. The peripheral support columns 19 define the setting range of the air pump 12, and at the same time, the support columns 19 isolate the adjacent air pumps 12. The air pump 12 is wrapped with a silica gel sleeve 18, preferably the air pump 12 is completely wrapped in the silica gel sleeve 18. By setting the silica gel sleeve and the silica gel suspension belt, the air pump is suspended on the support platform 11. And the ends of the support columns 19 are fixed to the bottom of the metal box body. In order to further reduce the transmission of the vibrations of the support columns 19 to the box body 3, a soft material can also be used to connect to the bottom of the support columns 19, such as using silica gel or rubber to bond to the bottom of the support columns 19.

[0036] The embodiment of the present invention also provides an intelligent adjustable mattress, which includes an airbag and the above-mentioned silent air pump box 1. Figure 3 It shows the overall structure of the intelligent adjustable mattress provided by the embodiment of the present invention. The intelligent adjustable mattress 4 includes a fabric layer 41, a comfort layer 42, an airbag layer 43, a first spring layer 44, a second spring layer 45, an air pump box body 3, a control box 47 and a silent protection layer 46. Among them, the fabric layer 41, the comfort layer 42, the airbag layer 43, the first spring layer 44, and the second spring layer 45 are arranged in sequence from top to bottom. The air pump box body 3, the control box 47 and the silent protection layer 46 are all arranged at the tail of the mattress, that is, at the foot position of the user. The fabric layer 41 and the comfort layer 42 provide the comfort and skin-friendly feeling of the mattress 4, and common materials of ordinary mattresses can be used according to the needs of users. The airbag layer 43 is mainly composed of a central airbag, the sponge around the airbag, and the sponge in the airbag gap. The first spring layer 44 and the second spring layer 45 mainly serve as the support layer of the mattress to provide a sense of resilience. These two spring layers are optional structures, that is, in some embodiments, these two layers of structures can be removed.

[0037] Specifically, the first spring layer 44 is provided with a groove structure at the tail for placing the box body 3 of the silent air pump box and the control box 47. The main purpose is to reduce the height of the silent air pump box and the control box, so that there is a thicker area above to ensure the comfort of users in this area and avoid a strong fault in softness and hardness. The silent protection layer 46 on the top of the silent air pump box is, firstly, to further optimize the comfort of users in this area and protect them when suffering impacts in this area. The silent protection layer 46 can be made of relatively hard sponge or spring.

[0038] Specifically, as Figure 4 shown, in the intelligent adjustable mattress provided by the present invention, the airbag layer 43 includes sponge 431 around the airbag, sponge 432 in the airbag gap, sponge 433 in the middle of the airbag, and airbag 434, with a silent air pump box on each side and a control box 47. Among them, the airbag 434 adopts a multi-region independent adjustable design, and airbags with a smaller width are used in the trunk area to increase the accuracy of the adjustment part. While airbags with a larger width are used in the leg area and the head area to save costs. The airbag provided by the embodiment of the present invention can be filled with only air, or springs or sponges can be implanted inside the airbag to ensure that the airbag still has sufficient elasticity when the air volume is insufficient and at the same time ensure smooth air flow during inflation and deflation. When implanting springs or sponges, the height of the springs or sponges is preferably not less than half of the internal height of the airbag.

[0039] In the embodiment of the present invention, the airbag can adopt three design schemes: wavy airbag, square airbag, and stacked airbag.

[0040] Specifically, the wavy airbag can be a large wavy airbag ( Figure 5 ) and a small wavy airbag ( Figure 6 ). Figure 5 As shown, the size of the large wavy airbag after inflation is 70*20*10 cm. Figure 6 As shown, the size of the small wavy airbag after inflation is 70*10*10 cm, and the large wavy airbag has a 6.5 cm drawstring in the middle. In an embodiment of the present invention, sponges are placed in the lower half of the airbag, and the sponges account for about half of the internal volume of the airbag. Figure 7 For Figure 5 the cross-sectional view of the large wavy airbag, with sponges filled in the lower half.

[0041] Specifically, the square airbag includes a large square airbag ( Figure 8 ) and a small square airbag ( Figure 9A) After inflation, the large square airbag has dimensions of 70*20*10 cm, and the small square airbag has dimensions of 70*10*10 cm. The large square airbag has a cross-shaped strap in the middle, and the strap has dimensions of 20*10*70 cm. Preferably, the interior (lower part) of the square airbag is filled with sponge, as Figure 9B shown.

[0042] Specifically, there are two types of laminated airbags. One type is that a single airbag adopts a three-layer structure, as Figure 10 shown, and there is a through hole running through the upper and lower parts in the middle of the airbag. The other type is a three-layer airbag structure, as Figure 11 shown, and there is no through hole in the middle of the airbag, which is also called a solid airbag.

[0043] In a specific embodiment, there are two ways to connect and fix the airbag: zipper connection ( Figure 12 ) and snap connection ( Figure 13 ). The zipper connection is as Figure 12 shown. A zipper 435 is provided on the outer edge of the airbag, and it is fixedly connected to the outer frame through this zipper 435. Figure 13 shows the structure of the snap connection. A buckle is provided at the end of the airbag and is connected to the outer frame through a fixed buckle. Then the side strip of the outer frame and the outer edge of the airbag are sandwiched in the middle of the sponge and glued firmly with sponge spray adhesive, as Figure 14 shown.

[0044] Sponge is set around the airbag mainly to fix the airbag and make the contour of the whole mattress more distinct. Usually, some relatively hard sponges are used. The function of the sponge in the middle is: to fix the outer edges of the airbags on the left and right sides, and also to fill the gaps on the left and right sides of the airbag to obtain a better sleeping feeling. The sponge in the airbag gap is mainly filled in the gap between the front and back of the airbag to reduce the discomfort caused by the uneven surface of the airbag in the inflated state.

[0045] The silent air pump box and the control box are placed at the end of the bed, that is, the position where the user's feet are. The advantage of this setting is: it brings a sense of security to the user and at the same time reduces the spread of noise. The inflation ports of the airbags on the left and right beds are respectively connected to the silent air pump box inside, and the central control box is mainly used to control the switches of the air pumps, air valves, etc. of the silent boxes on both sides, as well as the air pressure sensing and data processing. The air pressure sensing is mainly used to measure the air pressure of each airbag.

[0046] Specifically, the airbag material in the embodiment of the present invention can be PVC, TPU, rubber, silicone, PE, PU, PI, etc., and the softness and hardness of the airbag can be adjusted by inflating and deflating.

[0047] In addition to the above-mentioned silent air pump box and multi-region independently adjustable airbags, the intelligent adjustable mattress provided by the present invention further includes a pressure sensor, a data unit, and a control unit. The personal sleep information and algorithm parameters of the user are obtained through pre-entry to complete the personalized parameter customization of the mattress.

[0048] Specifically, the above-mentioned data unit mainly collects, analyzes, and processes the input analog small air pressure signals. Structurally, the data unit includes a pressure sensing and amplifying circuit, an ADC circuit, a main control part, etc. The sensing and amplifying circuit mainly filters and amplifies the original analog small signals of the air pressure of each airbag. The ADC circuit converts the amplified signal into an analog-to-digital conversion. The main control part mainly performs data preprocessing, algorithm processing, and analysis on the digital signal.

[0049] Specifically, the above-mentioned control unit mainly controls the air pump and air valve according to the output of the data unit. The control signal output by the main control unit controls the on-off of the air pump and air valve through a driving MOS transistor.

[0050] The above-mentioned method of obtaining the personal sleep information and algorithm parameters of the user through pre-entry to complete the personalized parameter customization of the mattress is to let the user enter some information such as height, weight, gender, and some basic information of body shape (such as shoulder width, chest circumference, waist circumference, hip circumference, etc.) when first using the mattress. It is also possible to enter the user's clothing size and pants size, or enter the user's body shape, such as H-shaped, O-shaped, V-shaped, A-shaped, etc.), as well as the pressure information of the basic sleeping posture, that is, according to several predetermined postures, such as lying flat, lying on the side, etc., the system will collect the air pressure data of the user in this sleeping posture and store it. The above information will be combined as the user's sleep information, and some basic parameters during the adjustment of the mattress will be obtained, so as to achieve the purpose of personalized customization of the mattress.

[0051] Figure 15Shows the internal control system structure diagram of the intelligent adjustable mattress provided by an embodiment of the present invention. The hardware system of the intelligent adjustable mattress mainly includes a pressure sensor, an 8-channel analog switch, a filter amplification circuit, an ADC analog-to-digital conversion module, a main control chip, a memory, a communication module (such as Wifi or Bluetooth, etc.), and a control drive circuit for the air pump and air valve. Among them, the pressure sensor is connected to the airbag, which can collect the air pressure of each airbag in real time, and then transmit the signals of these pressure sensors to an 8-channel analog switch, so as to save the number of filter amplification circuits and ADCs in the following. The pressure acquisition adopts the time-division multiplexing method, which greatly saves costs. The filter amplification circuit mainly amplifies the small signals of the pressure sensor and filters out some high-frequency noises. Then, after ADC analog-to-digital conversion, it is input into the MCU. The MCU mainly functions as a data processing center, a control center, and a wireless signal transmission control. The memory mainly stores the personal customization data of the user during the pre-entry process, such as height, weight, body pressure data in various sleeping postures, etc., as well as the user's overnight sleep data, which will be transmitted to the smart phone via Bluetooth. The user can view his sleep report through the App.

[0052] Specifically, the way of data pre-entry is as Figure 16 shown. Before the first use, the user first needs to manually enter personal basic information, including height, weight, gender, etc. Then, the user's body shape can be entered. There are two selection methods. The first is to enter information such as the user's shoulder width, chest circumference, waist circumference, hip circumference, etc., or the user can enter his own upper and lower clothing sizes, or enter the user's body shape, such as H-shaped, O-shaped, V-shaped, A-shaped, etc. After the first two entries, the user's general body model is initially formed. Next is the body pressure entry in various sleeping postures. The user lies on the bed in the specified sleeping posture according to the prompt, and the mattress will collect the pressure in this sleeping posture and store it, providing parameters for the subsequent sleeping posture recognition algorithm. According to the above information, the personal customization is completed, and the customization parameters are formed, that is, the adjustment range of the user in various sleeping postures. For example, according to the height and weight, it can be roughly known which airbag areas the user's various parts are in. And knowing the user's approximate BMI, according to the BMI and the subsequent entry of the body shape, it can be known how much air should be inflated or deflated in each part of the user. For example, if a user has a large hip circumference, then when lying flat, the airbag in the hip area should be deflated more; for a person with a wide shoulder width, then during side lying, the shoulder airbag should be adjusted more. Thus, the pre-entry process before the user uses is completed.

[0053] Next, during the actual sleep process, the pressure sensor will collect the real-time pressure data of each airbag, and through the sleeping position recognition algorithm, identify the user's current sleeping position. For example, the air pressure matrix of each current airbag can be compared with the pre-recorded air pressure matrices in various sleeping positions through an algorithm recognition. This recognition process can be regarded as a pattern recognition problem. Further, it can be regarded as a classification problem, and the sleeping position recognition can be completed through machine learning or deep learning algorithms. After the sleeping position recognition is completed, the position recognition needs to be carried out, that is, to identify the numbers of the airbags where the key parts of the user's shoulders, back, waist, hips, legs, feet, etc. are located. For example, the air pressure gradient of each airbag and the current sleeping position can be found, and combined with the body shape and height data actually entered by the user before, to judge the airbag where the user's part is located. For example, for waist recognition, through the user's height, the number of the airbag where the user's waist is located can be roughly judged. Usually, due to the S-shaped curve of the human spine at the waist position, when lying flat, there is often a large elevation gradient from the waist to the hips, and combined with the user's actual body shape, find the airbag number with the largest increase in body pressure, which can be positioned as the waist position.

[0054] After completing the sleeping position recognition and the user's position recognition, it is known how each airbag should be inflated and deflated. As for how much to inflate and deflate, it is necessary to combine the adjustment amplitude in various sleeping positions of the user obtained after pre-recording before, control the inflation and deflation time, and achieve the most comfortable adjustment.

[0055] Those skilled in the art can clearly understand that for the convenience and conciseness of description, only the above-mentioned division of each functional unit and module is used as an example. In actual applications, the above-mentioned functions can be allocated to different functional units and modules according to needs, that is, the internal structure of the device is divided into different functional units or modules to complete all or part of the functions described above.

[0056] The above-mentioned embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
