Description

Technical Field

[0001] The utility model relates to the technical field of home textile products, in particular to a quilt which is easy to disassemble and wash. Background Art

[0002] A quilt is a type of bedding. It is a rectangular piece of cloth that is large enough to cover the human body. It is generally used to keep warm during sleep. A quilt is usually made of a quilt cover or a sheet, also called a quilt cover, wrapped with cotton wool or a quilt core. A quilt made of cotton is called a cotton quilt. In addition to cotton quilts, it can also be made of artificial fibers such as wool, silk or acrylic fiber. At present, the quilts used by people are all provided with an opening on the quilt cover, and a rope or zipper is provided on the opening. When putting on the quilt core, first insert the quilt core body from the opening, then align the four corners of the quilt core with the four corners of the quilt cover, stretch it, and finally make the quilt core flat in the quilt cover.

[0003] Early cotton wool was heavy and could be used for heating in winter. Most quilts were made of cotton. Therefore, the quilts were heavy. When pulling the quilt cover on the surface of the quilt, you would not pull the quilt cover but not the cotton wool. However, with the improvement of people's living conditions, the weight of cotton wool is getting lighter and lighter, and the warmth retention effect is still very good. For example, it is made of artificial fibers such as wool, silk or acrylic fiber; the materials of quilt covers are gradually diversified and advanced. Therefore, with the change of quilt material and lightweight development, the following phenomenon is easy to occur during use: often when you wake up, the cotton wool in the quilt cover is shrunk into a ball, and the four corners or edges of the quilt cover are "vacuumed". Before using it again, you have to spend time and effort to arrange the quilt cover and cotton wool to make the two fit together completely.

[0004] Prior art example 1, referring to patent document CN211483865U, discloses a quilt fastener, which relates to the technical field of daily necessities, and solves the technical problem that the quilt core and quilt cover have no fixing device and are easy to shift. The quilt fastener includes a first fixing member, a second fixing member, a lock core and an unlocking device. The first fixing member includes a buckle seat and a cover body. The buckle seat and the cover body are relatively covered together and form a cavity for the lock core to be accommodated inside. The unlocking device is arranged between the lock core and the cover body. The second fixing member includes a nail seat, a steel needle and a clamping assembly. The steel needle is detachably connected to the nail seat through the clamping assembly. After the steel needle passes through the cover body and the unlocking device, it is locked by the lock core in a locked state. When the unlocking device is pressed, the steel needle can be pulled out of the locked state from the first fixing member. Specifically, the unlocking device includes a support plate, a pressing portion and a contact portion. The support plate is an inverted U-shaped plate structure, and the two free ends of the support plate are inclined outward. The pressing portion is vertically arranged at the two free ends of the support plate. The pressing portion is also a plate-shaped structure, and the middle part of the long side of the pressing portion is connected to the free end of the support plate, and the contact portion is vertically arranged in the middle of the bottom of the support plate; the unlocking device is in contact with the lock core through the contact portion; when the unlocking device is placed on the top of the lock core, the support plate and the pressing portion of the unlocking device have no contact with the buckle seat, so that the unlocking device is suspended above the buckle seat. Example 1 has certain disadvantages. For example, this type of quilt fastener is very practical, but it also has some detailed disadvantages. The existing quilt fasteners are implemented by inserting pins into the base, but the pins are usually exposed. During daily use, there is a certain probability that the pins will be separated from the base due to external force. If the pins are separated without knowing it, it will cause physical harm to consumers. In addition, for children, they will pull out the pins out of curiosity, which also causes the pins to be separated from the base under abnormal use.

[0005] Prior art example 2, referring to patent document CN216675371U, discloses a quilt fastener, including a fastener body and a pin, a pin lock core is provided in the fastener body, a first plug hole is provided in the fastener body, the pin is inserted into the fastener body through the first plug hole and forms a locking fit with the pin lock core, a push-to-unlock switch is also provided in the fastener body, the push-to-unlock switch acts on the pin lock core to switch the pin lock core between an unlocked state and a locked state; a safety locking mechanism is provided in the fastener body, the safety locking mechanism can act on the push-to-unlock switch, so that the push-to-unlock switch cannot be pressed down. The utility model can play a similar role to the common child lock function, with a limit lock to the push-to-unlock switch, the push-to-unlock switch will not be able to be pressed, so that the pin lock core remains in a locked state, and then the pin will not be separated from the lock core, and it will not cause physical harm to consumers, and play an effective protective role. Example 2 has certain disadvantages, for example: 1. The insertion needles destructively penetrate the quilt cover, causing the quilt cover to be easily damaged and the service life of the quilt cover to be reduced; 2. The quilt fastener will be partially exposed outside the quilt cover, affecting the appearance and causing discomfort when in contact with the human body. Summary of the invention

[0038] Embodiment 1

[0039] Reference Figure 1 to Figure 7 , a quilt that is easy to disassemble and wash, comprising a quilt cover 1, a quilt core 2, and a quilt cover 1 fixer; the quilt cover 1 fixer comprises:

[0040] A quilt core 2 fixing assembly, which is detachably connected to the outside of the quilt core 2, comprises a first quilt core fixing cover 31 disposed below the quilt core 2, and a second quilt core fixing cover 32 disposed above the quilt core 2, wherein the first quilt core fixing cover 31 is provided with a needle post 311, and the second quilt core fixing cover 32 is provided with a needle hole 321, wherein the needle post 311 passes through the quilt core 2 and is inserted into the needle hole 321, so that the first quilt core fixing cover 31 is fixedly connected with the second quilt core fixing cover 32, and the quilt core 2 is clamped between the first quilt core fixing cover 31 and the second quilt core fixing cover 32;

[0041] The quilt cover 1 fixing assembly is detachably connected to the inner side of the quilt cover 1, and includes a first quilt cover fixing seat 41 arranged on one side of the quilt cover 1, and a second quilt cover fixing seat 42 arranged on the other side of the quilt cover 1; the first quilt cover fixing seat 41 can be assembled into one piece with the first quilt core fixing cover body 31, and the second quilt cover fixing seat 42 can be assembled into one piece with the second quilt core fixing cover body 32.

[0042] The above content is the basic structural scheme of the utility model. When in use, first operate the quilt core 2 fixing assembly, adjust the position of the first quilt core fixing cover body 31 with the needle column 311 and the quilt core 2, then insert the needle column 311 from one side of the quilt core 2 and out from the other side, then align the needle hole 321 of the second quilt core fixing cover body 32 with the needle column 311, so that the needle column 311 is inserted into the needle hole 321, thereby fixing the first quilt core fixing cover body 31 and the second quilt core fixing cover body 32, and clamping the quilt core 2 between the first quilt core fixing cover body 31 and the second quilt core fixing cover body 32. Next, the first quilt cover fixing seat 41 and the second quilt cover fixing seat 42 are respectively connected and fixed to the inner side of the quilt cover 1, and then the first quilt cover fixing seat 41 is assembled with the first quilt core fixing cover body 31, and the second quilt cover fixing seat 42 is assembled with the second quilt core fixing cover body 32, so as to connect the quilt cover 1 and the quilt core 2 together, which can effectively prevent the two from being separated during use, so as to provide a good user experience.

[0043] It is worth mentioning that in order to facilitate the insertion of the needle column 311 into the needle hole 321 and prevent it from being easily disengaged after insertion, the preferred structure adopted is: the needle hole 321 includes a large hole section 3211 and a small hole section 3212 that are connected in sequence from the outside to the inside, and the needle column 311 forms a clearance fit with the large hole section 3211, and the needle column 311 forms an interference fit with the small hole section 3212. After assembly, since the fit formed by the needle column 311 and the small hole section 3212 has a large contact friction force, the needle column 311 will not be separated from the needle hole 321 in the case of a small external impact force, so as to ensure stability during use. If disassembly is required, the user holds the first quilt fixed cover body 31 and the second quilt fixed cover body 32, and applies opposite forces to the two, so as to overcome the friction and remove the needle column 311 from the needle hole 321.

[0044] Conventionally, the ring groove 43 is set on the quilt core 2, so every time the quilt cover 1 is changed, the hanging wire 11 needs to be disassembled and rewound with the ring groove 43, which is very inconvenient in operation and is prone to breakage after repeated use. In order to solve the above defects, the method adopted is: the first quilt cover fixing seat 41 and the second quilt cover fixing seat 42 are both provided with a ring groove 43, and the quilt cover 1 has a hanging wire 11, and the hanging wire 11 can be wound in the ring groove 43 to fix the first quilt cover fixing seat 41 and the second quilt cover fixing seat 42 to the quilt cover 1 respectively. Therefore, once the quilt cover 1 fixing assembly (the first quilt cover fixing seat 41 and the second quilt cover fixing seat 42) is fixed to the quilt cover 1 for the first time, when the quilt cover 1 is disassembled and washed later, it is not necessary to disassemble the quilt cover 1 from the quilt cover 1 fixing assembly, but only to disassemble the quilt cover 1 fixing assembly and the quilt core 2 fixing assembly, so it is simple in operation and will not damage the hanging wire 11.

[0045] It should be noted that there are various ways to connect the first quilt cover fixing seat 41 and the second quilt cover fixing seat 42 to the quilt cover 1, and the above examples are only preferred embodiments.

[0046] Embodiment 2

[0047] In the structural scheme of the first embodiment, there are various connection structural schemes between the quilt core 2 fixing assembly and the quilt cover 1 fixing assembly. Two preferred methods are provided here, as follows:

[0048] 1. Magnetic structure: refer to Figure 1 to Figure 4The first quilt core fixing cover body 31 and the second quilt core fixing cover body 32 are both provided with an annular groove 33, in which a magnet seat 34 is installed, and the magnet seat 34 has a plurality of magnets 35; the first quilt cover fixing seat 41 and the second quilt cover fixing seat 42 are both protrudingly provided with a magnetic block 44, and the magnetic block 44 can generate a magnetic force with the magnet 35, so that the first quilt cover fixing seat 41 is adsorbed on the first quilt cover fixing seat 41, and the second quilt cover fixing seat 42 is adsorbed on the second quilt cover fixing seat 42.

[0049] It is worth mentioning that the plurality of magnets 35 are preferably arranged in a Halbach array. Due to the mutual superposition of the parallel magnetic field and the radial magnetic field after the decomposition of the Halbach array magnet 35, the magnetic field strength on the other side is greatly improved, breaking the magnetic field distribution structure of the conventional magnet, so that the inner side of the magnet seat 34 forms a strong magnetic side 35a, and the outer side forms a weak magnetic side 35b. Furthermore, a slot 36 is provided at the center of the magnet seat 35, and the magnetic block 44 can extend into the slot 36, and the slot 36 is located on the strong magnetic side 35a.

[0050] Therefore, the magnets 35 of the same model, material and size can generate a larger magnetic field in the local area due to the change in arrangement, thereby generating a greater magnetic attraction force on the magnetic block 44, and playing a more obvious magnetic connection and limiting role. When disassembling, the user holds the quilt cover 1 fixing component by hand or clamps it with a tool, applies external force to overcome the magnetic attraction force, and then separates the quilt cover 1 fixing component (magnetic block 44) from the quilt core 2 fixing component (magnet 35).

[0051] 2. Physical connection structure: refer to Figure 5 The first quilt core fixing cover body 31 and the second quilt core fixing cover body 32 are both provided with connecting lock grooves 37, and the first quilt cover fixing seat 41 and the second quilt cover fixing seat 42 are both protruding with connecting hooks 45, and the connecting hooks 45 can be inserted into the connecting lock grooves 37, so as to fix the first quilt cover fixing seat 41 to the first quilt cover fixing seat 41, and fix the second quilt cover fixing seat 42 to the second quilt cover fixing seat 42.

[0052] Furthermore, the connecting hook 45 has an extending section 451 and a hook section 452, the connecting lock groove 37 has an opening area 371 and a locking area 372, the extending section 451 corresponds to entering into the opening area 371 to provide a disassembly and assembly path, the hook section 452 corresponds to being inserted into the locking area 372, and the hook section 452 abuts against the inner wall of the locking area 372 to form a limited anti-detachment fit.

[0053] Preferably, the hook section 452 is in an undulating wave shape (not shown in the figure), and the upper and lower ends of the hook section 452 are both against the inner wall of the locking area 372 and form an interference fit. Among them, the connecting hook 45 is an elastic metal sheet, which has a certain elasticity and can recover by itself after deformation. The wavy hook section 452 can form multiple contact points when it cooperates with the inner wall of the locking area 372, thereby forming sufficient plugging and pulling force to prevent the phenomenon of disengagement due to slight external force; in addition, due to the certain deformation force, when the user applies force to the connecting hook 45 in the correct direction, it can also separate the connecting hook 45 from the connecting lock groove 37 in a timely and easy manner.

[0054] Embodiment 3

[0055] Based on the structure of any of the above embodiments, the functions of the quilt are enriched, and more structural solutions are adopted as follows: Figure 7 The quilt cover 1 is provided with a temperature-sensitive region 12, and the temperature-sensitive region 12 is coated with a temperature-sensitive coating layer 13, and the temperature-sensitive coating layer 13 has a critical temperature;

[0056] When the temperature at the temperature-sensitive area 12 is lower than the critical temperature, the temperature-sensitive coating layer 13 is in a first color state;

[0057] When the temperature at the temperature-sensitive area 12 is higher than the critical temperature, the temperature-sensitive paint layer 13 is in a second color state.

[0058] Taking the critical temperature of 37°C as an example, when the user uses the quilt, the temperature of the quilt gradually rises, and the temperature sensing area 12 can sense the temperature change of the quilt in real time. When the temperature of the quilt exceeds the critical temperature of 37°C, the temperature sensing coating layer 13 changes color from the first color state to the second color state. The user can clearly observe the color change, thereby determining whether the quilt being used meets the usage requirements of the current temperature environment, and making timely and correct judgments on whether to replace the thick or thin quilt core 2, thereby preventing the occurrence of unsuitable quilts for long-term use and improving the usage experience of the quilt.

[0059] It is worth noting that other technical solutions of the present invention belong to the prior art and will not be described in detail.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
