Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, 2 and 3, the present invention is a schematic view of a disposable protective cover with a function of filtering germs (hereinafter referred to as a disposable protective cover), which comprises a cover body 1 with an opening 11 and a tightening part 2 formed around the opening of the cover body, wherein the opening of the cover body is suitable for sleeving a quilt cover object 100 such as a microphone, a headset, a stethoscope head or an earphone, so that the quilt cover object 100 is sleeved with the cover to avoid direct contact with saliva or sweat, thereby achieving protection. In this embodiment, the sleeve body 1 is enclosed by the base material that satisfies the sound effect, the base material at least includes skin 12, inlayer 13 and inlays the filter layer 14 of establishing between skin and inlayer in the thickness direction, this filter layer 14 has static adsorption characteristic at least, can make this disposable protective sleeve have powerful filtering quality like this, and spray or sweat etc. pass the skin and are close to the filter layer when using disposable protective sleeve after, can be adsorbed on the surface by static, can't permeate through, and protectiveness is excellent, avoids the user to take place bacterial infection or cross infection etc..
Referring to fig. 1, 2 and 3, in the present embodiment, the outer layer 12 and the inner layer 13 are made of spun-bonded nonwoven fabric or composite nonwoven fabric, which has good sound-transmitting effect and supporting effect and is not easy to tear. The filter layer 14 is melt-blown cloth, and is subjected to high-pressure electret treatment to ensure that the sleeve has strong filtering performance, and spray passes through the outer layer to be close to the filter layer and then is electrostatically adsorbed on the surface. In actual production, in order to improve the functionality of the outer layer 12 and the inner layer 13, a flame retardant and a softener can be added into the raw materials for manufacturing the outer layer 12 and the inner layer 13, wherein the flame retardant is used for preventing smoke and fire from burning, and the softener is used for reducing gaps in a cloth layer and is more suitable for objects to be sleeved, such as microphones, headsets, stethoscope heads or earphones. In this embodiment, in order to ensure the sound-transmitting effect, the thickness of the base material must be controlled to be relatively thin, and for this reason, the grammage of the outer layer and the inner layer of the base material of this embodiment is consistent, and is preferably 12 g/square meter; the gram weight of the filter layer is larger than that of the inner layer, preferably 14 g/square meter, and the thickness of the silk threads is controlled by adjusting parameters such as supply of a metering pump, mesh and traction speed of a net curtain in the existing non-woven fabric manufacturing process so as to obtain a base material with corresponding weight and performance, and the base material is used for manufacturing the disposable protective sleeve.
Referring to fig. 1 and 3, in the present embodiment, when the disposable protective cover is manufactured, the welding portion 15 formed by heat sealing of the substrate through mold pressing is shaped into the cover main body 1, the distribution track of the welding portion 15 determines the shape of the cover main body, and the welding portion divides the substrate enclosing into the cover main body into a first sheet body 16 and a second sheet body 17 which are symmetrical in the front-back direction; the opening 11 of the sleeve main body is arranged between the first sheet body 16 and the second sheet body 17, and the tightening part 2 is arranged on the opposite part of the first sheet body and the second sheet body. This structural design reaches convenient preparation, and satisfies automated production, utilizes the characteristic of non-woven fabrics to come the heat-seal, connects closely, firmly, the stable quality of the disposable protective cover who obtains, and with the 100 assorted sheets of quilt cover object, use on emboliaing the quilt cover object with opening 11 during the use, the portion 2 of tightening further cooperates and ties tightly to the effect that disposable protective cover cup jointed on the quilt cover object is more firm.
Referring to fig. 1 and 3, in this embodiment, the first sheet 16 and the second sheet 17 are formed by bending a same substrate, the tightening portion 2 includes a channel 21 disposed at the periphery of the opening of the sleeve main body and a tightening strap 22 disposed in the channel, the channel 21 is formed by folding the periphery of the opening of the sleeve main body outwards and fixing the opening on the sleeve main body, the tightening strap 22 is an elastic strap, and the tightening strap disposed in the channel is in a stretched state, so that the opening of the sleeve main body is normally contracted, and thus, after the disposable protective sleeve is sleeved on a sleeved object such as a microphone, an earphone, a stethoscope head or an earphone, the tightening portion 2 automatically tightens and clamps, so that the effect of the disposable protective sleeve sleeved on the sleeved object is firmer.
Of course, the tightening part 2 may also be an elastic band fixed on the inner side or the outer side of the opening of the sleeve body and providing the opening with expansion and contraction characteristics, that is, the elastic band may be fixed on the inner side or the outer side of the opening of the sleeve body by heat sealing, and the tightening function may also be achieved, which is not described in any detail herein.
The utility model discloses a disposable protective cover main part is enclosed to close by the substrate that satisfies logical sound effect and constitutes, the substrate is at least including skin, inlayer and inlay the filter layer of establishing between skin and inlayer in the thickness direction, and this filter layer has the electrostatic adsorption characteristic at least, makes this disposable protective cover have powerful filtering quality, and spray or sweat etc. pass the skin when using disposable protective cover and are close to the filter layer after, can be adsorbed by static on the surface, can't see through, and protectiveness and practicality are excellent, can the wide use, better satisfying customer user demand.
Of course, the present invention has been described in detail with reference to the embodiments, and only for the purpose of illustrating the technical conception and the features of the present invention, the purpose of the present invention is to enable those skilled in the art to understand the contents of the present invention and implement the same, therefore, all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
