Detailed Description
The invention is further described below with reference to specific embodiments:
referring to fig. 1 to 5, a height adjustment pillow includes: the pillow comprises a pillow body 1, a pillow core and a pillow core, wherein the pillow body is provided with a horizontal bottom surface 11 attached to a supporting surface, and the section of one surface of the pillow core, which is in contact with the head of a human body, along the vertical direction is a curve 12 with one end continuously distributed; the end of the curve 12 close to the body of the user is provided with a first peak, and the end far away from the body of the user is provided with a second peak; a wave trough is formed between the first wave crest and the second wave crest;
the first wave crest correspondingly supports the neck of a user, and the wave trough correspondingly supports the head of the user; a detection part 13 extends outwards from the tail end of one end of the curve 12 close to the body of the user, and a pressure monitoring unit is arranged in the detection part 13; when the human body is in the supine state, a cavity is formed between the shoulder and neck of the human body and the detection part 13; when the human body is in a side lying state, the shoulders of the human body are in pressing contact with the detection part 13; therefore, the pressure monitoring unit receives very small pressure when the human body is in the supine state, and the pressure monitoring unit receives very large pressure when the human body is in the lateral state. Therefore, the sleeping postures of the human body can be accurately distinguished.
The horizontal bottom surface of the pillow body 1 is provided with two cavities 14 and 15, one of the cavities is provided with a height adjusting mechanism, the other cavity is provided with a control mechanism for controlling the height adjusting mechanism to act, and when a human body lies on the back or on the side, the height adjusting mechanism adjusts the height of the pillow body 1.
In this embodiment, the height adjustment mechanism includes at least two layers of airbag units 21 stacked; each air bag unit 21 has at least two inflation chambers 22 therein; in the two adjacent layers of airbag units 21, after the airbag unit 21 located in the upper layer is fully inflated, the lowest point of each inflation cavity 22 is correspondingly adhered to the highest point of each inflation cavity 22 after the airbag unit 21 located in the lower layer is fully inflated.
The inflation cavities 22 in each airbag unit 21 are parallel to each other, a sealing member is arranged between the inflation cavity 22 and the inflation cavity 22, and the inflation cavity 22 is communicated with two ends of the inflation cavity 22; and each air bag unit 21 has an inflation and deflation valve connected to the inflation chamber 22. Thus arranged, only a portion of the area of one air-bag unit 21 is the inflation chamber 22, and the other portion is the sealing chamber. Only the inflation chamber 22 is inflated during inflation, so that the required inflation amount is greatly reduced, and the inflation speed can be greatly enhanced.
The lower air bag unit 21 among the different air bag units 21 is inflated first, and after being completely filled, the upper air bag unit 21 is inflated again.
The height adjustment mechanism further includes a control unit that controls inflation or deflation of the air bag unit 21.
The control unit comprises an air pump 22, an air duct 23 and a silencing unit; the air pump 22 inflates the airbag unit 21 through the vent tube 23.
The silencing unit comprises a sleeve 221 sleeved outside the air pump 22; the air pump 22 is arranged in the sleeve 221 through a support piece 222 and does not directly contact with the inner wall of the sleeve 221; thus, the noise that the air pump 22 should produce for vibration during operation is eliminated by the sleeve 221.
The outer wall of the sleeve 221 is provided with a plurality of through holes communicated to the inner wall; a second sleeve is covered outside the sleeve 221. Due to the through holes 223, the sleeve 221 forms a perforated plate shape, and further muffles sound by utilizing the principle of perforated plate resonance sound muffling.
In this embodiment, the supporting member 222 is an elastic suspension member, one end of which is connected to the inner wall of the sleeve 221, and the other end of which is connected to the air pump 22; thereby suspending the air pump 22 within the sleeve 221; alternatively, the support member is a flexible material disposed between the outer wall of the air pump 22 and the inner wall of the sleeve 221.
The inner wall of the sleeve 221 is further provided with a sound absorbing material and a sound insulating material in a stacked manner, and neither of the sound absorbing material and the sound insulating material is in contact with the air pump 22. The sound absorbing material and the sound insulating material can isolate and absorb noise generated by the air pump in the operation process, and further reduce the noise source.
In addition, the silencing unit further comprises at least one silencing chamber 24 connected in series in the vent pipeline 23, the cross-sectional area of the silencing chamber 24 is far larger than that of the vent pipeline 23, and the high-speed airflow in the vent pipeline 23 flows into the next vent pipeline 23 after expanding and decelerating through the silencing chamber 24. The air flow enters the silencing chamber 24 from the upper section of the pipeline 2, expands and buffers, and then enters the next section of the pipeline 3. In the present embodiment, there are two silencing chambers 24, and the lengths of the two silencing chambers 24 are different, so that the frequencies of sound that can pass through each silencing chamber 24 are different. Thus arranged, the air flow enters the silencing chamber 24 in an expanded form for buffering, thereby effectively reducing the generation of pulsating air flow.
Further, a pressure valve 25 is arranged between the silencing chambers 24, after the air pressure in the upper silencing chamber 24 reaches a set value, the pressure valve 25 is opened, and the air enters the lower silencing chamber 24. The presence of the pressure valve further increases the residence time of the gas in the upper muffling chamber 24, further reducing the generation of pulsating gas flows.
The air outlet end of the upper section of the vent pipeline 23 and the air inlet end of the lower section of the vent pipeline 23 respectively extend into the silencing chamber 24. The length of the air outlet end of the upper section of the vent pipeline 23 extending into the silencing chamber 24 is different from the length of the air inlet end of the lower section of the vent pipeline 23 extending into the silencing chamber 24.
Specifically, the length of the air outlet end of the upper section of the vent pipeline 23 extending into the silencing chamber 1 is 1/4 of the length of the silencing chamber 24, so that noise of even times of passing frequency is eliminated; the air inlet end of the next stage ventilating duct 23 extends into the muffling chamber 24 by 1/2 the length of which is equal to the length of the muffling chamber 24, thereby eliminating noise of odd multiples of the passing frequency. In combination, the noise generated by the airflow is substantially eliminated.
The present invention is not limited to the foregoing embodiments. The above embodiments should not be taken as limiting the scope of the invention. Modifications and alterations will occur to others upon reading and understanding the preceding detailed description. The specific protection scope shall be subject to the claims.
