Description

Technical Field

[0001] The invention relates to the technical field of bathing or shampooing protective appliances, in particular to a shampooing protective cover. Background Art

[0002] Washing children's hair is a relatively difficult task. When children take a shower or wash their hair, the dirty water containing soap and shampoo flows down through the hair and often flows into the eyes, nose and ears, stinging the eyes, choking the nose, and filling the ears with water. It is harmful to children's health and can easily cause children to cry, making washing impossible.

[0003] In response to the aforementioned issues with children's hair washing, a variety of protective devices for children's hair washing are available on the market. These devices are typically worn between the user's ears and the hairline before shampooing. Currently, two main types of protective shampoo covers are used. One method involves controlling the flow of wastewater from the back of the user's head through the coordination of a waterproof pad, a ring, and a protective cover, preventing it from entering the eyes, nose, and ears. However, these protective shampoo covers typically utilize a waterproof pad and a ring for sealing. Because the ring is typically fully bonded to the waterproof pad during manufacture, the waterproof pad is limited by its shape. Furthermore, the shape of the user's head varies, making it difficult for the waterproof pad to fully conform to the user's head. This can lead to leakage in some areas, making it easy for wastewater to escape from unsealed areas and enter the user's eyes, nose, and ears, preventing proper shampooing. Secondly, the waterproof pad and the protective cover cooperate to control the flow of sewage from the back or surrounding of the user's head. However, the end of the waterproof pad usually needs to have a tie or buckle structure, and the shampooing protective cover usually needs to be fixed to the user's head by the tie or buckle structure when wearing it. Since the wearers of the shampooing protective cover are usually young children, the wearing process is likely to cause children to cry and various problems of non-cooperation, causing considerable inconvenience to the wearer. Summary of the Invention

[0004] Based on this, it is necessary to provide a shampooing protective cover with good sealing performance and easy wearing.

[0005] A shampooing protective cover comprises a sealing portion and an elastic member, wherein the edge of the sealing portion extends in a preset direction to form a water shield, the sealing portion is a non-closed structure, and the elastic member is a non-closed axisymmetric graphic structure, the two ends of the elastic member are fixedly or detachably connected to the two ends of the sealing portion, and the elastic member gradually tightens the sealing portion during the process of recovering the deformation when the protective cover is worn on the user's head, so that the sealing portion fits tightly on the user's head, and the sealing portion and the water shield are made of soft material.

[0006] In one embodiment, the elastic member includes a first elastic member or a second elastic member, and the first elastic member or the second elastic member is respectively connected to the sealing portion to form a mirror image structure.

[0007] In one embodiment, the contact surface between the outer layers at both ends of the sealing portion and the inner layers at both ends of the first elastic member has a preset area value, and a gap is formed between the outer layer of the sealing portion and the non-contact surface of the inner layer of the first elastic member.

[0008] In one embodiment, the contact surface between the outer layers of both ends of the sealing portion and the outer layers of both ends of the second elastic member is a preset area value, and a gap is formed between the inner layer of the sealing portion and the inner layer of the second elastic member.

[0009] In one embodiment, the hair washing protective cover further comprises an elastic member fixing member, one end of which is fixedly connected to the sealing portion, and the other end of which controls the first elastic member to move within a preset range of longitudinal displacement.

[0010] In one embodiment, the sealing portion is a solid structure, a hollow structure, or a combination of a solid and hollow structure.

[0011] In one embodiment, the sealing portion is made of solid soft rubber.

[0012] In one embodiment, the sealing portion is a hollow sealing air cushion.

[0013] In one embodiment, the two ends of the sealing portion are solid structures, and the extension structures on the two ends of the sealing portion are hollow structures.

[0014] In one embodiment, the sealing portion and the water shield are an integrally formed structure.

[0015] The above-mentioned shampooing protective cover is arranged by cooperating with the sealing part and the elastic part. The two ends of the elastic part are fixedly or detachably connected to the two ends of the sealing part. The opening width of the elastic part is smaller than the width of the user's head in the initial state. When the user wears the protective cover, the elastic part will be deformed. The elastic part gradually tightens the sealing part through the two ends of the elastic part during the process of recovering the deformation after the protective cover is worn on the user's head. Since the sealing part is made of soft material, the sealing part can fit tightly with the brain according to the shape characteristics of the user's brain, thereby preventing the shampooing protective cover from leaking. In addition, the shampooing protective cover can be quickly fixed on the user's head through the elastic part. It is simple and convenient to wear, so that the shampooing work can be carried out quickly and normally. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element. In contrast, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1As shown, a shampooing protective cover includes a sealing portion 100 and an elastic member 200. The edge of the sealing portion 100 extends in a preset direction to form a water shield 300. The sealing portion 100 is a non-closed structure, and the elastic member 200 is a non-closed axisymmetric graphic structure. The two end portions 210 of the elastic member 200 are fixedly or detachably connected to the two end portions 110 of the sealing portion 100. The elastic member 200 gradually tightens the sealing portion 100 during the process of recovering the deformation when the protective cover is worn on the user's head, so that the sealing portion 100 fits tightly on the user's head. The sealing portion 100 and the water shield 300 are made of soft material.

[0027] In one embodiment, the elastic member 200 includes a first elastic member 220 or a second elastic member 230 , and the first elastic member 220 or the second elastic member 230 is respectively connected to the sealing portion 100 to form a mirror image structure.

[0028] like Figure 1 As shown, in one embodiment, the contact surface between the outer layer 111 of the two ends 110 of the sealing part 100 and the inner layer 221 of the two ends of the first elastic member 220 is a preset area value, and a gap 240 is formed between the outer layer 111 of the sealing part 100 and the non-contact surface of the inner layer 221 of the first elastic member 220.

[0029] like Figure 2 As shown, in one embodiment, the contact surface between the outer layer 111 of the two ends 110 of the sealing part 100 and the outer layer 231 of the two ends of the second elastic member 230 is a preset area value, and a gap 250 is formed between the inner layer 112 of the sealing part 100 and the inner layer 232 of the second elastic member 230.

[0030] In one embodiment, the hair washing protective cover further includes an elastic member fixing member 400 , one end of which is fixedly connected to the sealing portion 100 , and the other end of which controls the first elastic member 220 to move within a preset range of longitudinal displacement.

[0031] In one embodiment, the sealing portion 100 is a solid structure, a hollow structure, or a combination of a solid and hollow structure.

[0032] like Figure 3 As shown, in one embodiment, the sealing portion 100 is made of solid soft rubber.

[0033] like Figure 4 As shown, in one embodiment, the sealing portion 100 is a hollow sealing air cushion.

[0034] like Figure 5As shown, in one embodiment, the two ends of the sealing portion are solid structures, and the extension structures on the two ends of the sealing portion are hollow structures.

[0035] In one embodiment, the sealing portion 100 and the water shield 300 are an integrally formed structure.

[0036] The edge of the sealing portion 100 extends in a preset direction to form a water shield 300. The water shield 300 can be formed by extending upward, downward, or in parallel at the top edge of the sealing portion 100, or by extending upward, downward, or in parallel at the bottom edge of the sealing portion 100. The angle formed by the sealing portion 100 and the water shield 300 is set according to actual needs. The sealing portion 100 is a non-closed structure, for example, it can be a non-closed elliptical, circular structure or a planar graphic structure. The elastic member 200 is a non-closed axisymmetric graphic structure. The elastic member 200 is an axisymmetric structure, for example, an elliptical, circular, or square axisymmetric graphic. The elastic member 200 is rigid, not easy to stretch, and has a certain resilience. It is made of hard plastic or metal material, for example, ABS, nylon, PP, PPSU. The two ends 210 of the elastic member and the two ends 110 of the sealing portion can be fixed by bonding, riveting, or screwing. The sealing portion 100 and the water shield 300 are made of a soft material that can be arbitrarily deformed, such as plastic, silica gel, rubber, silicone rubber, thermoplastic elastomer, or airtight and watertight textiles.

[0037] In the initial state, because the sealing portion 100 is a non-closed structure, an opening is formed between the two ends 110 of the sealing portion, and the two ends 210 of the elastic member are fixedly or detachably connected to the two ends 110 of the sealing portion. Therefore, except that the two ends 210 of the elastic member are connected to the two ends 110 of the sealing portion, there is no contact at other positions. Under the joint force of the two ends 210 of the elastic member and the two ends 110 of the sealing portion, the opening between the two ends 110 of the sealing portion is smaller than the width of the user's head. When the shampooing protective cover is worn on the user's head, the elastic member 200 will produce a certain degree of deformation, which can be adjusted according to the user's head. The wearing position is appropriately adjusted according to the wearer's head size. After wearing, the elastic part 200 needs to restore its deformation. In the process of the elastic part 200 gradually retracting, the two ends 210 of the elastic part drive the two ends 110 of the sealing part to gradually move toward each other, so that the sealing part 100 is gradually tightened. Because the sealing part 100 is made of soft material, the sealing part 100 is more flexible. With the external force of the two ends 210 of the elastic part, it is easier to fit the wearer's brain according to the outer shape structure of the wearer's brain. During the shampooing process, the water shield 300 can prevent sewage from flowing out of the shampooer's face.

[0038] In this way, the shampooing protective shield is arranged in coordination with the sealing portion 100 and the elastic member 200, and the two end portions 210 of the elastic member are fixedly or detachably connected to the two end portions 110 of the sealing portion. The opening width of the elastic member 200 is smaller than the width of the user's head in the initial state. When the user wears the protective shield, the elastic member will deform. When the protective shield is worn on the user's head, the elastic member gradually tightens the sealing portion 100 through the two end portions 210 of the elastic member during the process of recovering the deformation. Since the sealing portion 100 is made of soft material, the sealing portion 100 can fit closely to the brain according to the shape characteristics of the user's brain, thereby preventing the shampooing protective shield from leaking. Moreover, the shampooing protective shield can be quickly fixed to the user's head through the elastic member 200. It is simple and convenient to wear, so that shampooing can be carried out quickly and normally.

[0039] Example 1: In one embodiment, the contact surface between the outer layer 111 of the two ends 110 of the sealing part 100 and the inner layer 221 of the two ends of the first elastic member 220 is a preset area value, and a gap 240 is formed between the non-contact surface between the outer layer 111 of the sealing part 100 and the inner layer 221 of the first elastic member 220.

[0040] The sealing portion 100 and the first elastic member 220 only need to be fixed at their ends. The contact area between the outer layer 111 of the two ends 110 of the sealing portion 100 and the inner layer 221 of the two ends of the first elastic member 220 is set according to actual needs, that is, the two ends of the first elastic member 220 can drive the sealing portion 100 to tighten. A gap 240 is formed between the non-contact surface of the outer layer 111 of the sealing portion 100 and the inner layer 221 of the first elastic member 220. That is, the first elastic member 220 surrounds the outer edge of the sealing portion 100. Except for the two ends, the other surfaces do not contact each other, which facilitates the first elastic member 220 to tighten the sealing portion 100.

[0041] Furthermore, in order to prevent the first elastic member 220 from moving up and down significantly, the shampooing protective cover also includes an elastic member fixing member 400, one end of which is fixedly connected to the sealing portion 100, and the other end controls the first elastic member 220 to move within a preset range of longitudinal displacement.

[0042] The elastic member fixing member 400 can be one or more. The elastic member fixing member 400 can be independent of the sealing portion 100 or integrally formed with the sealing portion 100. Installed on the side of the sealing portion 100 proximal to the first elastic member 220, it effectively controls the large vertical movement of the first elastic member 220. The elastic member fixing member 400 can be a soft adhesive tape, a rubber ring, or a locking buckle. This ensures that the first elastic member 220 and the sealing portion 100 are substantially aligned, preventing the first elastic member 220 from being misaligned with the sealing portion 100 and preventing the sealing portion 100 from being tightened.

[0043] like Figure 6 As shown, the elastic member fixing member 400 further includes a first elastic member fixing member 410. One end of the first elastic member fixing member 410 is fixedly mounted on the sealing portion 100, and the other end is sleeved on the first elastic member 220 to form a gap with the front and rear ends of the first elastic member 220. The first elastic member fixing member 410 is a closed structure, such as a rectangular parallelepiped, cube, or cylindrical structure. The bottom supports the bottom of the first elastic member 220, and the top has a preset gap with the top of the first elastic member 220. The specific gap size is set according to actual conditions. The front end or rear end of the first elastic member fixing member 410 has a certain gap with the front or rear end of the first elastic member 220, respectively, to facilitate the forward and backward movement of the first elastic member 220 during deformation or recovery.

[0044] like Figure 7 As shown, the elastic member fixing member 400 further includes a second elastic member fixing member 420, one end of which is fixedly mounted on the sealing portion 100, and the other end of which is passed through the first elastic member 220. The first elastic member 220 can move forward and backward by a preset distance on the second elastic member fixing member 420. In this way, the second elastic member fixing member 420 has a stopper 421, which can control the movement distance of the first elastic member 220, facilitating the first elastic member 220 to move back and forth between the stopper and the sealing portion 100.

[0045] Example 2: In one embodiment, the contact surface between the outer layer 111 of the two ends 110 of the sealing part 100 and the outer layer 231 of the two ends of the second elastic member 230 is a preset area value, and a gap 250 is formed between the inner layer 112 of the sealing part 100 and the inner layer 232 of the second elastic member 230.

[0046] The sealing portion 100 and the second elastic member 230 both have a non-enclosed pattern structure. The sealing portion 100 and the second elastic member 230 are simply fixed at their ends. The contact area between the outer layer 111 of the ends 110 of the sealing portion 100 and the outer layer 231 of the ends of the second elastic member 230 is set according to actual needs. That is, the ends of the second elastic member 230 can drive the sealing portion 100 to tighten. The second elastic member 230 and the first elastic member 220 can have mirror-image structures. Except for the contact at the ends, the sealing portion 100 and the second elastic member 230 are non-contact surfaces. A gap 250 is formed between the inner layer 112 of the sealing portion 100 and the inner layer 232 of the second elastic member 230. The specific size of the second elastic member 230 can be manufactured according to actual needs.

[0047] Furthermore, the sealing portion 100 is a solid structure, a hollow structure, or a combination of a solid and hollow structure.

[0048] Furthermore, the sealing portion 100 is made of solid soft rubber, which is one of soft PVC, silicone, EVA, POE, and TPES.

[0049] Furthermore, the sealing portion 100 is a hollow sealing air cushion. The internal space of the sealing portion 100 may be filled with a material or not filled with a material, and the filling material may be filled completely or partially, and the filling material may be a liquid (such as water), a gas (such as air), or solid particles (such as plastic particles).

[0050] Furthermore, in order to facilitate the installation of the sealing portion 100 and the elastic member 200, the two ends of the sealing portion 100 are solid structures, and the extension structures on the two ends of the sealing portion are hollow structures. If the two ends of the sealing portion 100 and the two ends of the elastic member 200 are connected by rivets, if the two ends of the sealing portion 100 are hollow sealing air cushions, if the rivets are installed in an improper position, it is easy to cause damage to the two ends of the sealing portion 100, affecting the normal use of the protective cover. Therefore, the two ends of the sealing portion 100 and the two ends of the elastic member 200 are preferably installed by bonding. Therefore, the two ends of the sealing portion 100 are designed to be solid structures, and the parts connected to the two ends of the sealing portion 100 are designed to be hollow structures, which can effectively avoid damage to the two ends of the sealing portion 100 and make the installation methods of the sealing portion 100 and the elastic member 200 more diverse.

[0051] Furthermore, the sealing portion 100 and the water shield 300 are integrally formed. The water shield 300 can be independent of the sealing portion 100 or integrally formed with the sealing portion 100, which is simpler and more convenient to manufacture.

[0052] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
