Description

Technical Field

[0001] This application relates to the technical field of daily necessities, and particularly to a plastic cup with a filtering function. Background Art

[0002] Drinking plain boiled water is a healthy lifestyle. However, sometimes in order to enhance the taste of water, other things such as tea leaves, ginger, red dates, wolfberries, and some medicinal herbs are soaked. To avoid sucking in the insoluble substances during drinking, a filter structure is usually provided inside the cup, such as the stainless steel filter in a thermos cup. However, sheet-like soaked substances tend to adhere to the inner wall of the cup, and when cleaning the cup, it is necessary to rinse the water multiple times to pour out all the soaked substances, which is rather wasteful of water. Summary of the Invention

[0003] The purpose of this application is to provide a plastic cup with a filtering function that is convenient to clean.

[0004] To achieve the above purpose, this application provides a plastic cup with a filtering function: including a main cup body, a filtering cup, and a draining cup. The draining cup is located between the filtering cup and the main cup body. The main cup body is sleeved outside the draining cup, and the draining cup is sleeved outside the filtering cup. The height of the main cup body is greater than that of the draining cup, and the height of the filtering cup is less than that of the draining cup. The outer side surface of the draining cup is adapted to fit with the inner wall of the main cup body, and the inner side surface of the draining cup is adapted to fit with the outer side surface of the filtering cup. The bottom of the draining cup is a filter plate, and the bottom of the filtering cup is a bottom cover. The bottom cover is provided with lower filter holes penetrating the upper and lower surfaces. Insoluble substances are adapted to be placed between the bottom cover and the filter plate and do not directly contact the smooth inner wall of the main cup body, thus avoiding adhesion.

[0005] As a preference, the top of the draining cup has a separating edge adapted to rest on the upper edge of the main cup body, and the top of the filtering cup has an outwardly expanding edge adapted to rest on the upper surface of the separating edge, forming a stacked layered structure.

[0006] As a preference, the outer side surfaces of the outwardly expanding edge and the separating edge are flush with the outer side surface of the main cup body, ensuring that the upper opening edge of the plastic cup is smooth and does not irritate the mouth.

[0007] As a preference, the upper end surface of the main cup body is provided with a first finger slot penetrating the outer side surface, which facilitates the separation of the draining cup from the main cup body.

[0008] As a preference, the lower surface of the outwardly expanding edge is provided with a second finger slot penetrating the outer side surface, which facilitates the separation of the filtering cup from the draining cup.

[0009] As a preference, the edge of the filter disc has a conical ring extending upward, and the bottom edge of the filter cup is adapted to rest on the upper end surface of the conical ring, providing additional positioning and support for the filter cup.

[0010] As a preference, the side wall of the draining cup is provided with convection holes and outer layer holes located above the conical ring, and the outer layer holes are located above the convection holes for forming a visual effect of a hollowed-out transparent plastic cup.

[0011] As a preference, the side wall of the filter cup is provided with side filter holes and inner layer holes. The side filter holes are close to the bottom of the filter cup, and the inner layer holes are located above the side filter holes. When the filter cup is mated with the draining cup, the inner layer holes are located below the outer layer holes to avoid visual interference with each other.

[0012] As a preference, the bottom surface and the top surface of the bottom cover are both arc surfaces and bulge upward to increase the space for accommodating insoluble substances.

[0013] Compared with the prior art, the beneficial effects of the present application are as follows:

[0014] (1) By designing the plastic cup into a separable three-layer structure and using the restraint effect of the filter cup and the draining cup to prevent the soaked objects from contacting the main cup body with a smooth inner wall, when cleaning the cup, it is not necessary to rinse it many times, only a simple rinse is needed, or even no water is required, and the operation process is faster, saving both time and water.

[0015] (2) The draining cup can completely separate the soaked objects from the liquid, and the removal of the soaked objects can be done without using water at all, directly shaking them off outside the sink, effectively reducing the probability of clogging of the drain pipe.

[0025] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence.

[0026] The terms "including" and "having" in the description and claims of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0027] Such as Figures 1-6The plastic cup with a filtering function shown in the figure includes three plastic structures: a main cup body 1, a filtering cup 2, and a draining cup 3. The draining cup 3 is located between the filtering cup 2 and the main cup body 1. The main cup body 1 is sleeved outside the draining cup 3, and the draining cup 3 is sleeved outside the filtering cup 2. The upper heights of the filtering cup 2, the draining cup 3, and the main cup body 1 decrease in sequence. The top of the draining cup 3 has a separating edge 301 that expands outward to form a ring, which just rests on the upper edge of the main cup body 1. The top of the filtering cup 2 also has an outwardly expanding edge 201 that expands radially outward, which just rests on the upper surface of the separating edge 301. The outer sides of the outwardly expanding edge 201 and the separating edge 301 are flush with the outer side of the main cup body 1, forming a flat rim at the upper opening of the entire plastic cup, so that there is less rubbing feeling when drinking water. A first finger slot 101 that penetrates the outer side is provided on the upper end surface of the main cup body 1. When the fingernail is inserted into the first finger slot 101, the draining cup 3 can be easily separated from the main cup body 1. A second finger slot 202 that penetrates the outer side is provided on the lower surface of the outwardly expanding edge 201. When the fingernail is inserted into the second finger slot 202, the filtering cup 2 can be easily separated from the draining cup 3.

[0028] To ensure that the three-layer structure can be nested together as required above, the height of the main cup body 1 is made greater than that of the draining cup 3, and the height of the filtering cup 2 is made less than that of the draining cup 3. The outer side of the draining cup 3 will fit with the inner wall of the main cup body 1 to form a sealed surface to prevent water from overflowing from the mating gap. Similarly, the inner wall of the draining cup 3 will fit with the outer side of the filtering cup 2 to play a role in preventing water leakage. The edge of the filter plate 302 has an upwardly extending tapered ring 303. A step is formed between the upper end of the tapered ring 303 and the inner wall of the draining cup 3. The bottom edge of the filtering cup 2 just rests on the upper end surface of the tapered ring 303, providing additional positioning and support for the bottom of the filtering cup 2.

[0029] The bottom of the described draining cup 3 is a filter plate 302. The filter plate 302 has many relatively narrow channels that only allow liquids to pass through, and it is difficult for insoluble substances such as tea leaves to pass through. The bottom of the filtering cup 2 is a bottom cover 203. The bottom cover 203 is located above the filter plate 302, and usually, both the bottom surface and the top surface of the bottom cover 203 are arc-shaped and bulge upward. In this way, the space between the bottom cover 203 and the filter plate 302 will be larger, which can accommodate more soaked substances. The bottom cover 203 is provided with a lower filter hole 204 that penetrates the upper and lower surfaces, which also allows liquids to pass through. Insoluble substances with a size larger than the lower filter hole 204 are difficult to pass through. Insoluble substances such as tea leaves are most suitable to be placed between the bottom cover 203 and the filter plate 302, so that one will neither drink the tea leaves nor need to rinse the cup during cleaning. The side wall of the draining cup 3 is provided with a convection hole 304 and an outer layer hole 305 located above the conical ring 303. The convection hole 304 is used to increase the passing speed of the water flow and avoid increasing the water flow resistance due to the too thin through holes of the filter plate 302. The outer layer hole 305 can make the transparent plastic cup form a hollow visual effect through the reflection and refraction of light by the inner wall. The outer layer hole 305 is located above the convection hole 304, so that the liquid can fully pass through the convection hole 304. The side wall of the filtering cup 2 is provided with a side filter hole 205 and an inner layer hole 206. The side filter hole 205 is also used to increase the water passing speed, and the inner layer hole 206 is also used to form a graphic effect on the plastic cup without printing. The side filter hole 205 is also close to the bottom of the filtering cup 2, so as to make full use of the side filter hole 205 during water filtering. The inner layer hole 206 is located above the side filter hole 205. Both the inner layer hole 206 and the outer layer hole 305 hardly participate in the solid-liquid separation function and only serve to decorate the plastic cup. When the filtering cup 2 is combined with the draining cup 3, the inner layer hole 206 is located below the outer layer hole 305 to avoid the mutual influence of the reflection and refraction effects of light and make the presented hollow structure effect become complicated.

[0030] Working principle: Taking the tea brewed in a commonly used cup in daily life as an example, when in use, first place the drain cup 3 into the column cup body, put the tea leaves onto the filter plate 302, then place the filter cup 2 into the drain cup 3, and then hot water can be poured in. After the hot water contacts the tea leaves for a few seconds, pour out the water in the plastic cup. The wetted tea leaves remain between the bottom cover 203 and the filter plate 302, and only the water for washing the tea is poured out. Then pour in hot water for the second time. After brewing for a while, it can be consumed. When brewing repeatedly for many times, the tea flavor gradually fades. Then, using the first finger slot 101, separate the filter cup 2 and the drain cup 3 from the main cup body 1, and then use the second finger slot 202 to separate the filter cup 2 from the drain cup 3 to shake off most of the tea leaves. Since water can pass through the through-hole structures on the filter cup 2 and the drain cup 3, the tea leaves that fail to be shaken off and adhere to the filter cup 2 and the drain cup 3 can be easily rinsed off. And the inner wall of the main cup body 1 without holes will not adhere to tea leaves, so there is no need to rinse and wash the cup repeatedly, saving water. Moreover, after cleaning the tea cup, most of the tea leaves are separated from the water, reducing the probability of blockage caused by pouring the tea water into the sewer.
