Description

A kind of improved pillow cover and its action method
Technical field
The invention belongs to bedding technical fields, are related to a kind of pillow cover, especially a kind of improved pillow cover and its effect Method.
Background technique
Pillow cover is the towel covered on pillow.Pervious pillow is all the cotton filled in a cloth bag or rice husk etc , it cleans highly difficult.As long as dirty cleaning pillow cover is all right after having pillow cover.
Pillow cover is mostly made with purified cotton yarns, also useful acrylic fibers line and cotton yarn.Have that yarn knits pillow cover and line knits pillow cover Two classes.There are jacquard weave, stamp, jacquard weave spraying decoration, jacquard weave embroidery, cut pile stamp, cut pile jacquard weave and knits lattice (anti-lattice) pillow cover etc..Fabric is tight It is close strong, it is soft and flexible, using comfortable.To protect pillowcase clean and tidy, decoration function is had concurrently.
Pillow cover condition on existing market is single, functionally lack of diversity.The pillow cover of monolithic is covered on pillow simultaneously On be easy to misplace or be detached from, cause to bring many artificial troubles for repeating to arrange, even result in not play and keep pillow clear Clean effect.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, one kind is proposed by conductive layer and carries out human body The discharge of electrostatic realizes that the storage of gas-liquid carries out mobility support by setting utricule, completes changing for multinomial health care effect Into pillow cover and its action method.
Object of the invention can be realized by the following technical scheme: a kind of improved pillow cover, folds be equipped with extremely from the bottom to top Few three layers, first layer is utricule interlayer, the second layer is conductive layer, third layer is ventilative surface layer, utricule interlayer, conductive layer and ventilative Surface layer is connected by the suture texture on periphery, and the utricule interlayer includes top and bottom, the periphery of the top and bottom It sutures, forms clip cavity between the top and bottom, be in that several utricules are arranged in the clip cavity, between several utricules By pipeline connection, the bottom setting of the utricule interlayer is connected to the gas-liquid hole of the utricule, and sealing is arranged on the gas-liquid hole Mouth, filling gas or liquid in the utricule and pipeline are also filled with cotton-wool in the utricule interlayer, if the cotton-wool is coated on The periphery of dry utricule and several pipelines, the conductive layer are to be interweaved with being formed by 50% silver fiber and 50% dacron thread longitude and latitude Fabric, several ventilation areas are uniformly distributed on the ventilative surface layer, and the knitting density of the ventilation area is the knitting of other regions The one third of density is to a quarter.
In above-mentioned improved pillow cover, magnetic force component, the magnetic force group is arranged in the four corners of utricule interlayer bottom surface Part includes fixed magnetic sheet and movable magnetic sheet, and the fixed magnetic sheet is packed on the bottom surface, the activity magnetic sheet be located at it is external with The fixed magnetic sheet forms magnetic attraction.
In above-mentioned improved pillow cover, setting folder capsule, described solid between the quadrangle of utricule interlayer top and bottom Determine magnetic sheet by colloid be adhered to it is described folder it is intracapsular.
In above-mentioned improved pillow cover, the utricule is plastic cement soft bag, and the pipeline is plastic hose.
In above-mentioned improved pillow cover, there is air hole, the air hole is in honeycomb arrangement, described in the cotton-wool Antimicrobial particles are filled in air hole.
In above-mentioned improved pillow cover, the top and bottom of the utricule interlayer are pure-cotton fabric, the top surface and Several air holes are uniformly distributed on bottom surface.
In above-mentioned improved pillow cover, the ventilative surface layer is linen-cotton fabric.
The action method of improved pillow cover, comprising the following steps:
1) it, when needing the filling gas into utricule and pipeline, needs to configure an inflator and passes through gas-liquid hole to utricule It inside inflates, the sealing function of internal gas is realized by sealing mouth, thus several utricules and the interior gas filled of several pipelines can With circulation, flexible support on the one hand is provided for head, headwork is on the other hand followed to be supported adjustment, optimization lies down comfortable Degree and sleep quality;
2) it, when needing to fill liquid into utricule and pipeline, needs to configure a syringe and passes through gas-liquid hole into utricule Liquid is perfused, the sealing function of internal liquid is realized by sealing mouth, thus several utricules and the interior liquid filled of several pipelines It can circulate, on the one hand provide flexible support for head, and headwork is followed to be supported adjustment, on the other hand scorching Season can reduce head temperature by heat absorption, realize refrigerant, fall fire using effect, optimize lie down comfort level and sleep matter Amount;
3) gap filling, is carried out by the cotton-wool in utricule interlayer and passes through the air hole in cotton-wool to provide flexible support Realize entire utricule interlayer can respiratory state, inhibit and eliminate bacterium by the antimicrobial particles in air hole, ensure people Body health;
4), when human body carries electrostatic, electric action is played using the silver fiber of conductive layer, the electrostatic on human body is held Continuous export, avoids adverse effect caused by human body static electrification;
5), by several ventilation areas breathed freely on surface layer, further promoted it is integrally-built can breathable properties, moreover it is possible to increase The heat-conductive characteristic of strong utricule, in favor of the endothermic effect of liquid in utricule.
In above-mentioned action method, the utricule interlayer patch of pillow cover is covered on the surface of pillow, utricule interlayer quadrangle is made The fixation magnetic sheet at place corresponds in the four corners of pillow, and four movable magnetic sheet one-to-one correspondence are placed on pillow quadrangle Under bottom surface, so that four groups of fixed magnetic sheets and movable magnetic sheet are attracted, so that the quadrangle of pillow is clamped by magnetic force, magnetic is thus just utilized Pillow cover is fixed on pillow by power, is avoided pillow cover dislocation and is slid, and the structure convenient for assembling and is split.
In above-mentioned action method, sealing mouth is packed on gas-liquid hole, seals the middle part setting elastic rubber ring of mouth, institute The center setting elastic shrinkage hole of elastic rubber ring is stated, blocking has cock cap on the elastic shrinkage hole, it needs to inflate or when fluid injection, Cock cap is unpluged, the needle mouth of the gas nozzle of inflator or syringe is protruded into elastic shrinkage hole and is inflated or fluid injection, is extracted after the completion Gas nozzle or needle mouth, cover cock cap again.
Compared with prior art, this improved pillow cover and its action method carry out the discharge of static electricity on human body by conductive layer, It realizes that the storage of gas-liquid carries out mobility support by setting utricule, and realizes that absorbing and cooling temperature keeps head salubrious, pass through magnetic force Effect carries out fixed installation of the pillow cover on pillow, and the easy operation realizing installation, splitting, and to sum up completes multinomial health care Effect promotes human body and lies down experience, improvement sleep quality.
