[0002] A thermos cup is a cup with insulation function. It is usually made of ceramic or stainless steel with a vacuum layer. It has a lid on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of water and other liquids inside to achieve the purpose of insulation.

[0003] For example, the travel thermos cup with publication number CN2120474U is composed of a cup body, a cup cover, a drinking water cover, a glass liner, a straw, and a sealing pad. The cup body and the cup cover are both plastic shells, and the space between the cup body and the glass liner is filled with insulation material. The cup cover and the cup body are connected by threads and sealed. When in use, the drinking water cover is unscrewed, and the straw floats up under the action of buoyancy, and the user absorbs water through the straw. However, people usually soak tea leaves and other soaked objects in the thermos cup. At this time, using a straw to drink the beverage in the cup will suck part of the soaked object into the straw, thereby blocking the straw, or directly sucking it into the mouth, causing inconvenience in drinking. Utility Model Content

[0004] The utility model provides a straw cup with a straw having a filter sleeve.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a straw cup, comprising a cup body, a cup cover covered on the top surface of the cup body, and a straw slidably connected to the cup cover, characterized in that a filter is sleeved on one end of the straw located in the cup body, and the bottom end of the straw extends into the filter, when the straw is used to absorb the drink, the tea leaves are located outside the filter, and there is a gap between the inner wall of the filter and the straw, and the filter has elastic deformation ability, so that when the straw is separated from the cup cover, the filter is deformed due to the squeezing of the cup cover.

[0006] A further preferred technical solution of the utility model is: a limiting ring is fixedly connected to the top of the filter liner, the limiting ring is elastic, and when the filter liner is sleeved outside the straw, the limiting ring is deformed.

[0007] A further preferred technical solution of the utility model is: an annular groove is provided on the outer peripheral wall of the suction tube, and when the filter sleeve is arranged outside the suction tube, the limiting ring is located in the annular groove.

[0008] A further preferred technical solution of the utility model is: the width of the annular groove is greater than the width of the limiting ring, and when the filter liner is deformed, the limiting ring slides in the annular groove.

[0009] A further preferred technical solution of the utility model is that a plurality of convex points are integrally formed on one side wall of the limiting ring close to the annular groove.

[0010] A further preferred technical solution of the utility model is: the filter chamber is provided with double layers, a gap exists between the two layers of the filter chamber, and the holes on the two layers of the filter chamber are arranged in a staggered manner.

[0011] A further preferred technical solution of the utility model is: a limiting ring is provided at one end of the straw outside the cup body, and when the limiting ring abuts against the top surface of the cup cover, a gap exists between the bottom surface of the filter and the inner bottom surface of the cup body.

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0025] Figure 1-Figure 3 As shown, a straw cup comprises a cup body 1, a cup cover 2 covering the top surface of the cup body 1 and a straw 3 slidably connected to the cup cover 2, one end of the straw 3 located in the cup body 1 is sleeved with a filter 5, the filter 5 is a sphere or an ellipsoid, which can be conveniently entered into the cup body 1 through the straw 3 inlet on the cup cover 2, the bottom end of the straw 3 extends into the filter 5, when the straw 3 is used to absorb beverage, the beverage enters the straw 3 through the filter 5 to be absorbed and drunk, while the tea leaves are located outside the filter 5, playing the role of filtering the tea leaves, the filter 5 has elastic deformation ability, so when the straw 3 is pulled outward to separate the straw 3 from the cup cover 2, the filter 5 is deformed due to the squeezing of the cup cover 2, thereby facilitating the separation of the straw 3 from the cup cover 2, and because there is a gap 9 between the inner circumferential wall of the filter 5 and the straw 3, a space is provided for the filter 5 to deform, thereby facilitating the deformation of the filter 5.

[0026] Figure 1-Figure 3 As shown, the top of the filter bile 5 is fixedly connected to a limiting ring 7, which is elastic and made of edible rubber. When the filter bile 5 is sleeved outside the straw 3, the limiting ring 7 is deformed. This design can increase the friction between the filter bile 5 and the straw 3, thereby making the connection between the filter bile 5 and the straw 3 more secure and preventing the filter bile 5 from being separated from the straw 3 during the process of drawing out the straw 3.

[0027] Figure 1-Figure 3 As shown, an annular groove 6 is provided on the outer peripheral wall of the straw 3, and the inner wall of the annular groove 6 is arc-shaped. When the filter 5 is sleeved outside the straw 3, the limiting ring 7 is located in the annular groove 6. This design further limits the longitudinal movement direction of the limiting ring 7. When the straw 3 is pulled out, the inner bottom surface of the annular groove 6 abuts against the limiting ring 7, thereby playing a limiting role and further avoiding the separation of the filter 5 and the straw 3.

[0028] Figure 1-Figure 3As shown, the width of the annular groove 6 is greater than the width of the limiting ring 7. Therefore, when the straw 3 is pulled out, the filter 5 is deformed due to the squeezing of the cup cover 2. At this time, since the straw 3 is pulled out from bottom to top, the limiting ring 7 is located in the annular groove 6 and gradually slides upward with the deformation of the filter 5, thereby facilitating the deformation of the filter 5 and the removal of the straw 3. This design improves the convenience of removing the straw 3.

[0029] Figure 1-Figure 3 As shown, a plurality of protrusions 8 are integrally formed on one side wall of the limiting ring 7 close to the annular groove 6. This design increases the contact area between the limiting ring 7 and the inner wall of the annular groove 6, thereby increasing the friction between the limiting ring 7 and the annular groove 6, making the connection between the filter 5 and the straw 3 more secure.

[0030] Figure 1-Figure 3 As shown, the filter 5 is provided with a double layer, and there is a gap 10 between the two layers of filter 5. The holes on the two layers of filter 5 are staggered. Therefore, when the volume of the soaked object is small, the staggered holes can block the small volume of the soaked object in the gap 10, thereby effectively preventing the soaked object from entering the straw 3 and affecting the drinking of the beverage. This design further improves the filtering effect of the filter 5.

[0031] Figure 1-Figure 3 As shown, a limiting ring 4 is provided at one end of the straw 3 outside the cup body 1. When the limiting ring 4 abuts against the top surface of the cup cover 2, a gap exists between the bottom surface of the filter 5 and the inner bottom surface of the cup body 1. This design enables the top end of the straw 3 to always be located outside the cup cover 2, thereby facilitating drinking, and can effectively prevent the straw 3 from falling completely into the cup body 1, and prevent the filter 5 from contacting the inner bottom surface of the cup body 1 to affect the filtering effect.

[0032] Figure 3-Figure 5 As shown, the limiting ring 7 is provided with an opening 11, and the depth of the opening 11 is less than the width of the limiting ring 7 to prevent the opening 11 from affecting the fixing effect of the limiting ring 7. When the opening 11 is closed, the limiting ring 7 is located in the annular groove 6. When the filter 5 needs to be removed, the casing is flipped downward through the opening 11 to separate the limiting ring 7 from the annular groove 6. At this time, since the fixing of the filter 5 and the straw 3 by the limiting ring 7 is released, the filter 5 can be easily removed by moving the filter 5 downward to complete the disassembly. This design facilitates the disassembly of the filter 5, and is convenient for cleaning and replacement of the filter 5 or single use of the straw 3.

[0033] The straw cup provided by the utility model is introduced above. The principle and implementation method of the utility model are described in this article using specific examples. The description of the above embodiments is only used to help understand the utility model and its core idea. It should be pointed out that for ordinary technicians in this technical field, the utility model can also be improved and modified without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
