Description

Technical Field

[0001] The present invention relates to the field of daily necessities, and particularly to a multifunctional tool for drying and sieving objects that can prevent water droplets, dust, and flies. Background Art

[0002] In modern life, the urbanization rate is very high and increasing rapidly, with many elevator buildings and small high-rise buildings. It is really inconvenient to dry things in elevator buildings and small high-rise buildings. If drying on the balcony, the sunlight is less and the irradiation time is short. If using a box to hold things and placing them on the drying rack protruding from the balcony to dry, when people upstairs dry clothes and quilts, water often drips down and wets the dried things. The higher the upper floors, the more serious this situation is. And flies will also contaminate the dried things, especially food, which is most afraid of fly contamination. It is also really inconvenient to sieve things in elevator buildings and small high-rise buildings. When sieving things, dust and debris fly everywhere, resulting in inhaling dust and getting covered with dust and debris, which is harmful to physical health and pollutes the indoor environment and the outdoor surrounding environment. Moreover, the dust and debris are directly sieved on the ground, dirtying the ground. Many people have suffered from these troubles. Sieves with trays and lids also cannot observe the inside situation without lifting the lid and have a single function without multifunctional uses. In addition to elevator buildings and small high-rise buildings, it is also inconvenient in single-family houses in rural and urban areas. The dried things are contaminated by flies, and when sieving things, dust and debris fly everywhere, resulting in inhaling dust and getting covered with dust and debris, which is harmful to physical health and pollutes the surrounding environment. And it is also inevitable that the dust and debris are directly sieved on the ground, dirtying the ground. In summary, there is an urgent need for a multifunctional tool for drying and sieving objects that can prevent water droplets, dust, and flies. Summary of the Invention

[0003] The purpose of the present invention is to provide a multifunctional tool for drying and sieving objects that can prevent water droplets, dust, and flies.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A multifunctional tool for drying and sieving objects that can prevent water droplets, dust, and flies, Solution 1: Figure 1 、 Figure 2 、 Figure 3 The tools are used in combination. Figure 3 The length and width of the bottom of the sieve box are based on the slightly lower position in the middle of the four side walls of the waterproof and fly-proof box, that is, 1 - 5 cm below the holes in the side walls of the waterproof and fly-proof box. In this way, there can be a volume space cavity of several centimeters in height under the bottom of the sieve box to accommodate the sieved dust and debris, and at the same time, it can also prevent the dust and debris from emerging. When sieving things, Figure 1 the sieve box is placed into Figure 3 the box, and at this time, Figure 1 the box can be used as Figure 1 the bottom box of the sieve box, Figure 3 and the lid covers Figure 2 ​Figure 3 The mouth of the sieve box. Figure 3 There is a sieve box under Figure 1 The box collects the sifted dust and debris. Figure 2 Cover with lid Figure 3 The mouth of the sieve box should be left to stand for a few minutes before opening. Figure 2 Lid, out Figure 3 Sieve box, Figure 1 Pour the dust and debris collected by the box into a trash can or trash bag, if necessary, and Figure 1 When the box does not contain much dust and debris, you can continue to sift things without dumping it out. When there is a lot of dust and debris, dump it out all at once. In this way, when sifting things, there will be no dust and debris flying all over the sky, inhaling dust and getting covered with dust and debris, which will harm your body and pollute the environment. The dust and debris will not be directly sifted on the ground and dirty the ground. And the tool material is transparent plastic material, so Figure 3 Sieve Box and Figure 1 The inside of the box can be seen clearly without opening the lid.

[0006] When you want to dry something, put it in Figure 1 In a waterproof and fly-proof box, Figure 2 Cover with lid Figure 1 The opening of the waterproof and fly-proof box is no longer afraid of water dripping from the clothes and quilts hung upstairs, nor is it afraid of flies contaminating the things being dried, especially food, which is most afraid of being contaminated by flies. Figure 1 The waterproof and fly-proof box has 2mm diameter circular holes evenly distributed on the upper part of the four walls, which can not only prevent flies from entering the box, but also allow the moisture of the objects to be dried to pass through the holes on the four walls of the box and dissipate into the air, thus drying the objects. And the tool material is transparent plastic material, so Figure 1 The condition of the items drying inside the ordinary waterproof and fly-proof box can be clearly seen without opening the lid.

[0007] Option 2: Figure 3 , Figure 4 , Figure 5 The tools are used in conjunction with each other. Figure 3 The length and width of the bottom of the sieve box are based on the size of the sieve box. Figure 4 The standard position is slightly below the middle of the walls of the four sides of the waterproof and fly-proof box, that is, 1-3 cm below the holes in the wall of the waterproof and fly-proof box. In this way, there is a volume space of several cm in height under the sieve box to accommodate the sieved dust and debris, while also preventing the emergence of dust and debris.

[0008] When you want to sift something, Figure 3 Sieve box into Figure 4 Inside the box, Figure 4 The box can be used as Figure 3The bottom box of the sieve box Figure 5 The lid covers Figure 3 the mouth of the sieve box. Figure 3 There is Figure 4 a box under the sieve box to hold the sifted dust and debris, Figure 5 The lid covers Figure 3 the mouth of the sieve box. After sieving, let it stand still for a few minutes and then lift the Figure 5 lid, take out the Figure 3 sieve box, and pour the Figure 4 dust and debris held by the box into a trash can or garbage bag. If you still need to sieve things, and Figure 4 when the dust and debris held by the box are not much, you can not pour them out first and continue to sieve things. Wait until there is more dust and debris and then pour them out at one time. In this way, when sieving things, the dust and debris will not fly all over the sky, and you will not inhale dust or get covered with dust and debris, which is harmful to the body and pollutes the environment. Nor will the dust and debris be directly sieved on the ground and dirty the ground. And the tool material is a transparent and light-transmitting plastic material. Therefore Figure 3 the situation inside the sieve box and Figure 4 the inside of the box can be clearly seen without lifting the lid.

[0009] When you want to dry things, put the things into Figure 4 the waterproof and fly-proof box, and then use Figure 5 the lid to cover Figure 4 the mouth of the waterproof and fly-proof box. In this way, you don't have to worry about the water dripping from the clothes and quilts dried upstairs, nor do you have to worry about flies polluting the dried things, especially food, which is most afraid of fly pollution. And Figure 4 there are evenly distributed round holes with a diameter of 2 mm in the upper part of the four walls of the waterproof and fly-proof box, which can not only prevent flies from entering the box, but also allow the moisture and gas of the object to be dried to pass through the holes in the four walls of the box and disperse into the air to dry the things. Figure 5 The length-width ratio of the top of the lid Figure 4 is 12 - 14 cm longer and wider than the length and width of the mouth of the box, Figure 5 and the four walls of the lid are 12 - 13 cm high. Figure 4 After covering the box with Figure 5 the lid, because there is a cavity of 6 - 7 cm between the four walls of the lid and the four walls of the box, this cavity is conducive to air flow. The moisture and gas of the object to be dried can pass through the holes in the four walls of the box and enter the cavity, and then disperse into the air from the cavity to dry the things. Because the bottom edge of the four walls of the lid exceeds the lowest holes of the box wall by 2 - 3 cm, it can prevent rainwater from entering the holes. Even in heavy rain, there is no need to worry. You no longer have to worry that when drying things on a sunny day, if you are not at home and it suddenly rains, the things will get wet. Nor do you have to worry that when drying things on a sunny day, you are worried that it will suddenly rain and you dare not go out or stay and watch the dried things and dare not do other things. And the tool material is a transparent and light-transmitting plastic material. Therefore Figure 4The inner surface of the box with enhanced waterproof and super fly-proof functions for drying things is clearly visible even without opening the lid.

[0010] For the waterproof and fly-proof boxes in the above Scheme 1 and Scheme 2, the length and width of the opening diameter of the box are 4 - 6 cm more than the length and width of the bottom of the box respectively, so as to keep the shape of the box larger at the top and smaller at the bottom, facilitating the overlapping and stacking of the boxes. The length and width of the opening diameter of the lid are 2 - 6 cm more than the length and width of the top surface of the lid respectively, so as to keep the shape of the lid smaller at the top and larger at the bottom, facilitating the overlapping and stacking of the lids. The length, width and shape of the opening diameter of the waterproof and fly-proof box are the same as those of the sieve box, and they can be used together with the same lid. The waterproof and fly-proof box, the sieve box and the lid can be matched to form a rectangular structure, a square structure or a circular structure, and the material is a transparent and light-transmitting plastic material or resin material. It is preferably selected from polymethyl methacrylate (PMMA) material and PET plastic material.

[0011] The beneficial effects of the present invention are as follows: When sieving things, there will be no dust and debris flying everywhere, which may cause inhalation of dust and getting covered with dust and debris, endangering physical health and polluting the environment, nor will the dust and debris be directly sieved on the ground to dirty the ground. Also, because the material of the tool is a transparent and light-transmitting plastic material, the situation inside the sieve box and the bottom box can be clearly seen even without opening the lid. When drying things, in Scheme 1, it is not afraid of the water dripping from drying clothes and quilts upstairs, and is no longer afraid of flies contaminating the dried things, especially food, which is most afraid of fly contamination. In Scheme 2, it not only has the functions of Scheme 1, but also has the function that even in heavy rain, it is not afraid, and no longer afraid that when drying things on a sunny day and suddenly changing to rain when people are not at home, the things will be wet, nor afraid of suddenly changing to rain on a sunny day when drying things and thus not daring to go out or having to guard the dried things and not being able to do other things. In Scheme 1 and Scheme 2, because the material of the tool is a transparent and light-transmitting plastic material, the situation of the things being dried can be clearly seen even without opening the lid, and it has multiple functions and can be used for multiple purposes.

[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0040] Solution 1: Figure 1 、 Figure 2 、 Figure 3 The tools of are used in a matching manner. Figure 3 The length and width of the bottom of the sieve box are based on the slightly lower position in the middle of the four walls of the waterproof and fly-proof box, that is, 1 - 5 cm below the holes in the wall of the waterproof and fly-proof box. In this way, there can be a volume space cavity with a height of several centimeters under the bottom of the sieve box to accommodate the sieved dust and debris, and at the same time, it can also prevent the dust and debris from emerging. Figure 1

[0041] When sieving things, Figure 3 Figure 1 The sieve box is placed into Figure 1 the box. At this time, Figure 3 the box can be used as Figure 2 the bottom support box of the sieve box. Figure 3 The lid covers Figure 2 the mouth of the sieve box. Things are sieved out of dust and debris through the uniformly distributed holes (10) of the bottom (9) of the sieve box with uniformly distributed holes. Figure 3 There is Figure 1 a box under the sieve box to receive the sieved dust and debris. Figure 2 The lid covers Figure 3 the mouth of the sieve box. After sieving, let it stand still for a few minutes and then lift the Figure 2 lid, take out Figure 3 the sieve box, and pour the Figure 1 dust and debris received by the box into the trash can or garbage bag. If you still need to sieve things, and Figure 1When the box does not contain much dust and debris, you can continue to sift things without dumping it out. When there is a lot of dust and debris, dump it out all at once. In this way, when sifting things, there will be no dust and debris flying all over the sky, inhaling dust and getting covered with dust and debris, which will harm your body and pollute the environment. The dust and debris will not be directly sifted on the ground and dirty the ground. And the tool material is transparent plastic material, so Figure 3 Sieve Box and Figure 1 The contents of the box can be seen clearly without opening the lid.

[0042] When you want to dry something, put it in Figure 1 In a waterproof and fly-proof box, Figure 2 Cover with lid Figure 1 The opening of the waterproof and fly-proof box is no longer afraid of water dripping from the clothes and quilts hung upstairs, nor is it afraid of flies contaminating the things being dried, especially food, which is most afraid of being contaminated by flies. Figure 1 The upper part of the four walls of the waterproof and fly-proof box is evenly distributed with circular holes with a diameter of 2 mm, that is, Figure 1 The holes (4) are evenly distributed on the wall of the box, which can prevent flies from entering the box and allow the moisture of the objects to pass through the holes on the four walls of the box. Figure 1 The holes (4) evenly distributed on the wall of the box are used to release the air into the air, thereby drying the items. The tool material is a transparent plastic material, so Figure 1 The condition of the items drying inside the ordinary waterproof and fly-proof box can be clearly seen without opening the lid.

[0043] Option 2: Figure 3 , Figure 4 , Figure 5 The tools are used in conjunction with each other. Figure 3 The length and width of the bottom of the sieve box are based on the size of the sieve box. Figure 4 The standard position is slightly below the middle of the four walls of the waterproof and fly-proof box, that is, 1-3 cm below the holes in the wall of the waterproof and fly-proof box. In this way, there is a volume space of several cm in height under the sieve box to accommodate the sieved dust and debris, while also preventing the emergence of dust and debris.

[0044] When you want to sift something, Figure 3 Sieve box into Figure 4 Inside the box, Figure 4 The box can be used as Figure 3 The bottom box of the sieve box, Figure 5 Cover with lid Figure 3 The mouth of the sieve box. The things are filtered out of dust and debris through the evenly distributed holes (10) of the bottom (9) of the sieve box, which are evenly distributed with holes. Figure 3 There is a sieve box under Figure 4 The box collects the sifted dust and debris. Figure 5Cover with lid Figure 3 The mouth of the sieve box should be left to stand for a few minutes before opening. Figure 5 Cover, take out Figure 3 Sieve box, Figure 4 Pour the dust and debris collected by the box into a trash can or trash bag, if necessary, and Figure 4 When the box does not contain much dust and debris, you can continue to sift things without dumping it out. When there is a lot of dust and debris, dump it out all at once. In this way, when sifting things, there will be no dust and debris flying all over the sky, inhaling dust and getting covered with dust and debris, which will harm your body and pollute the environment. The dust and debris will not be directly sifted on the ground and dirty the ground. And the tool material is transparent plastic material, so Figure 3 Sieve Box and Figure 4 The contents of the box can be seen clearly without opening the lid.

[0045] When you want to dry something, put it in Figure 4 In a waterproof and fly-proof box, Figure 5 Cover with lid Figure 4 The opening of the waterproof and fly-proof box is no longer afraid of water dripping from the clothes and quilts hung upstairs, nor is it afraid of flies contaminating the things being dried, especially food, which is most afraid of being contaminated by flies. Figure 4 The upper part of the four walls of the waterproof and fly-proof box is evenly distributed with circular holes with a diameter of 2 mm, that is, Figure 4 The holes (4) evenly distributed on the box wall can prevent flies from entering the box, and can also allow moisture from the objects to pass through the holes on the four walls of the box. Figure 4 The holes (4) evenly distributed on the wall of the box are released into the air to dry the items. Figure 5 The four walls of the lid are 12-13cm high. Figure 4 When the box is closed Figure 5 After the lid is closed, there is a 6-7 cm cavity between the four walls of the lid and the four walls of the box. This cavity is conducive to air flow, and the moisture gas of the objects being dried can pass through the holes in the four walls of the box. Figure 4 The holes (4) evenly distributed on the box wall enter the cavity, and then dissipate from the cavity into the air to dry the items. Because the bottom edges of the four walls of the lid, that is, the bottom edges of the lid opening (18) are 2-3 cm higher than the lowest holes of the box wall, it can prevent rain from entering the holes. Even if it rains heavily, there is no need to worry about the items getting wet when people are not at home on a sunny day. There is no need to worry about the items being dried on a sunny day and then suddenly turning to rain and not daring to go out or not being able to do other things while the items are drying. The tool is made of transparent plastic material, so Figure 4 The items inside the waterproof and fly-proof box can be seen clearly without opening the lid.

[0046] In the above specific embodiments, the length-width ratio of the opening of the waterproof and fly-proof box in Solution 1 and Solution 2 is 4-6 cm more than the length and width of the bottom of the box, so as to keep the shape of the box larger at the top and smaller at the bottom, which is convenient for stacking the boxes. The length-width ratio of the opening of the lid is 2-6 cm more than the length and width of the top surface of the lid, so as to keep the shape of the lid smaller at the top and larger at the bottom, which is convenient for stacking the lids. The shape of the edge of the opening of the waterproof and fly-proof box is exactly the same as that of the edge of the opening of the supporting sieve box, and they can be used together with the same lid.

[0047] When using the tools in Solution 1 Figure 1 、 Figure 2 、 Figure 3 for matching, Figure 2 the length-width ratio of the edge of the lid excluding the inner surface of the wall thickness Figure 1 is 0.4 cm more than the length and width of the edge of the ordinary waterproof and super fly-proof box, which is convenient for covering the lid and leaving some gaps to facilitate air flow and drying things. Figure 3 The length-width size ratio of the edge of the sieve box Figure 1 is 4 mm more than the length and width of the edge of the ordinary waterproof and super fly-proof box. Figure 3 The length-width size and shape of the edge of the sieve box Figure 2 are symmetrically corresponding and exactly the same as the length-width size and shape of the edge of the lid.

[0048] When using the tools in Solution 2 Figure 3 、 Figure 4 、 Figure 5 for matching, Figure 5 the length-width ratio of the top of the lid excluding the inner surface of the wall thickness Figure 4 is 0.5-1 cm more than the length and width of the edge of the enhanced waterproof and super fly-proof box, which is convenient for covering the lid and leaving some gaps to facilitate air flow and drying things. Figure 3 The length-width size ratio of the edge of the sieve box Figure 4 is 0.5-1 cm more than the length and width of the edge of the enhanced waterproof and super fly-proof box.

[0049] Figure 1 And Figure 4 There are evenly distributed circular holes in the upper part of the wall bodies of the four sides of the waterproof and fly-proof box. The distance between the upper, lower, left and right of the edge of the circular hole and the edge of the circular hole is 2-3 mm.

[0050] The above waterproof and fly-proof box, sieve box and lid can be matched in a rectangular structure, a square structure or a circular structure. The length, width and diameter size of the matching shape structure are not limited. For the matching rectangular structure, it is preferably 30-50 cm in mouth width and 40-60 cm in mouth length. For the matching square structure, it is preferably 30-50 cm in mouth length and width. For the matching circular structure, it is preferably 40-60 cm in mouth diameter. The waterproof and fly-proof box, sieve box and lid with the matching square structure and the matching circular structure Figure 1Figure 2 Figure 3 Figure 4 Figure 5 The specific structural principles and functions of the waterproof and fly-proof box, the sieve box, and the lid are the same, only the shapes are different.
