Description

Technical Field

[0001] The present invention relates to the technical field of daily necessities, and particularly to a drinking cup and its cup lid. Background Art

[0002] Currently, the filter screens of the tea-making cups on the market are generally arranged in the upper part of the cup body. When the cup lid is unscrewed to drink the tea, the filter screen remains on the cup body to effectively filter the tea leaves. One disadvantage of such a tea-making cup is that when it is necessary to pour out the tea leaves to replace with new ones, or to clean the inner wall of the cup body, it is necessary to touch the filter screen with hands to take it out of the cup body, which not only causes hygiene problems, but also easily leads to the problem of forgetting and losing the filter screen after it is taken out. Therefore, how to conveniently and hygienically pick and place the filter screen has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0003] In view of this, the present invention provides a drinking cup and its cup lid. The cup lid is provided with a mechanism that can lock the filter screen and the cup lid into one body, so that the filter screen can be picked and placed more conveniently and hygienically.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A cup lid of a drinking cup, comprising a lid body and a slider slidably connected to the lid body. When the slider is in the first working position, the slider can form a hook with the filter screen of the drinking cup so that the filter screen and the lid body are locked into one body. When the slider is in the second working position, the locking between the filter screen and the lid body is released.

[0006] Optionally, in the above cup lid, it further comprises a rotating member rotatably connected to the lid body. The rotating member is provided with a driving part for driving the slider, and the slider is provided with a matching part for cooperating with the driving part to form a cam pair.

[0007] Optionally, in the above cup lid, a groove is recessed on the upper surface of the lid body.

[0008] Optionally, in the above-mentioned cup lid, the rotating member is coaxially arranged with the lid body. The lower surface of the rotating member has a cylinder located in the groove. The driving portion is a guiding groove formed on the lower surface of the cylinder, and the cooperating portion is a convex post arranged on the upper surface of the slider. When the rotating member is rotated to make the convex post reach the first position of the guiding groove, the outer end of the pin body extends from the through hole to the outside of the groove. When the rotating member is rotated in the reverse direction to make the convex post reach the second position of the guiding groove, the outer end of the pin body retracts from the outside of the groove back into the through hole.

[0009] Optionally, in the above-mentioned cup lid, the groove wall of the guiding groove is provided with a limiting protrusion for stopping the convex post at the first position and / or the second position.

[0010] Optionally, in the above-mentioned cup lid, the guiding groove is an arc-shaped groove.

[0011] Optionally, in the above-mentioned cup lid, it further includes a fastener coaxially arranged with the rotating member. The fastener has a plurality of elastic hooks evenly distributed around the axis of the rotating member. A first clamping portion is arranged on one side of the elastic hook away from the axis of the rotating member.

[0015] According to the above technical solution, in the cup lid of the drinking cup provided by the present invention, the slider is slidably connected to the lid body. Since the slider can form a hook with the filter screen of the drinking cup when it is in the first working position, locking the filter screen and the lid body into one body, when the filter screen needs to be removed, just slide the slider to the first working position first, and then the filter screen can be removed together with the cup lid when the cup lid is removed. During the entire removal process, only the cup lid is touched by hand, and the filter screen will not be touched. Moreover, after the filter screen is removed with the cup lid, it is stored on the lower surface of the cup lid. Just invert the cup lid to prevent the filter screen from contacting the tabletop and keep the filter screen hygienic. After replacing the new tea leaves or cleaning the inner wall of the cup body, screw the cup lid back onto the cup body again. The filter screen is placed back into the cup body together with the cup lid. During the entire replacement process, only the cup lid is touched by hand, and the filter screen will not be touched. Since the locking between the filter screen and the lid body is released when the slider is in the second working position, just slide the slider to the second working position first to remove the cup lid for normal drinking. At this time, the filter screen will not be removed together with the cup lid but remains on the cup body to effectively filter the tea leaves. In summary, using the cup lid provided by the present invention can make it more convenient and hygienic to remove and replace the filter screen. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] For ease of understanding, the present invention will be further described below with reference to the accompanying drawings.

[0035] See Figure 1 , the drinking cup provided by the embodiment of the present invention includes a cup body 10, a filter screen 9 and a cup lid. Among them, the cup lid includes a lid body 7 and a rotating member 3 coaxially arranged with the lid body 7. The structure of the lid body 7 is as shown in Figure 2 and Figure 3 . A groove is formed by recessing the upper surface of the lid body 7. A sliding groove 71 is provided at the bottom of the groove, and a through hole 72 communicating with the sliding groove 71 is formed in the side wall of the groove. A slider 5 is arranged in the sliding groove 71. The structure of the slider 5 is as shown in Figure 4 . A convex column 51 is provided on the upper surface of the slider 5, and a pin body 52 is provided on the side surface of the slider 5. The assembly drawing of the slider 5 and the lid body 7 is as shown in Figure 5As shown, the pin body 52 of the slider 5 faces the side of the chute 71 close to the through hole 72, and the pin body 52 can pass through the through hole 72. The structure of the rotating member 3 is as shown in Figure 6 shown, and in combination with Figures 9 to 12 it can be known that the lower surface of the rotating member 3 has a cylinder located in the groove of the cover body 7. A guiding groove 31 designed according to the cam principle for cooperating with the convex post 51 is provided on the lower surface of the cylinder. When the rotating member 3 is rotated so that the convex post 51 reaches the first position of the guiding groove 31, the outer end of the pin body 52 extends from the through hole 72 to the outside of the groove (i.e., the state shown in Figure 9 and Figure 10 ), and when the rotating member 3 is rotated in the reverse direction so that the convex post 51 reaches the second position of the guiding groove 31, the outer end of the pin body 52 retracts from the outside of the groove back to the through hole 72 (i.e., the state shown in Figure 11 and Figure 12 ).

[0036] As shown in Figure 8 , in order to facilitate indicating the working state of the rotating member 3, a locking mark and an unlocking mark are provided at a position near the outer edge of the upper surface of the rotating member 3, and positioning marks for cooperating with the locking mark and the unlocking mark are provided on the outer peripheral surface of the cover body 7. Figure 9 is the state when the locking mark of the rotating member 3 aligns with the positioning mark of the cover body 7. At this time, the convex post 51 is located at the first position of the guiding groove 31. Figure 11 is the state when the unlocking mark of the rotating member 3 aligns with the positioning mark of the cover body 7. At this time, the convex post 51 is located at the second position of the guiding groove 31. The guiding groove 31 is designed according to the cam principle. The distance from the first position to the rotation center of the rotating member 3 is not equal to the distance from the second position to the rotation center of the rotating member 3. The first position is farther from the rotation center of the rotating member 3 than the second position. Therefore, when the rotating member 3 rotates relative to the cover body 7, a force is generated between the groove wall of the guiding groove 31 and the outer surface of the convex post 51. This force drives the slider 5 to slide along the chute 71, thereby changing the position of the slider 5.

[0037] As shown in Figure 9 and Figure 10 , when the convex post 51 is located at the first position of the guiding groove 31, the outer end of the pin body 52 of the slider 5 has passed through the through hole 72 of the cover body 7. At this time, if the cup lid is removed from the cup body 10, the part of the pin body 52 exposed from the through hole 72 will form a hook with the rolling ribs on the inner wall of the filter screen 9. Therefore, the filter screen 9 will be removed together. It can be seen that when the convex post 51 is located at the first position of the guiding groove 31, the filter screen 9 and the cup lid are locked together as a whole. As shown in Figure 11 and Figure 12As shown, when the convex post 51 is located at the second position of the guiding groove 31, the outer end of the pin body 52 retracts into the through hole 72. At this time, if the cup lid is removed from the cup body 10, the filter screen 9 will not be removed together. In summary, by changing the position of the slider 5, the filter screen 9 can be selectively locked to the cup lid as a whole or the lock between the two can be released.

[0038] The following describes the specific steps for replacing new tea leaves or cleaning the inner wall of the cup body. First, rotate the rotating member 3 relative to the cover body 7 so that the locking mark on the rotating member 3 aligns with the positioning mark on the cover body 7 to complete the locking of the filter screen 9 and the cup lid. Then, screw the cover body 7 off the cup body 10. Since the filter screen 9 is locked to the cup lid as a whole, the filter screen 9 is removed together with the cover body 7. Moreover, the filter screen 9 is received on the cover body 7, which can effectively prevent it from being lost due to forgetting. After removing the cup lid, the tea leaves in the cup body 10 can be poured out smoothly. Therefore, new tea leaves can be put into the cup body 10 and boiling water can be poured in, or the inner wall of the cup body 10 can be cleaned. After that, screw the cup lid back onto the cup body 10 and rotate the rotating member 3 relative to the cover body 7 so that the unlocking mark on the rotating member 3 aligns with the positioning mark on the cover body 7 to release the lock between the filter screen 9 and the cup lid. The subsequent drinking process is the same as that of a traditional drinking cup. Screw the cover body 7 off the cup body 10. Since the filter screen 9 is elastically engaged with the cup body 10 and not locked to the cup lid as a whole, the filter screen 9 remains on the cup body 10 to effectively filter the tea leaves. From the above entire process, it can be seen that when replacing new tea leaves or cleaning the inner wall of the cup body, the drinking cup of the present invention does not require human hands to contact the filter screen 9, and the operation is convenient and hygienic. In addition, after the filter screen 9 is removed with the cup lid, it is received on the lower surface of the cover body 7. As Figure 15 shown, just by inverting the cover body 7, it can prevent the filter screen 9 from contacting the tabletop and keep the filter screen 9 hygienic.

[0039] As Figure 5 shown, in this embodiment, the cover body 7 is provided with two symmetrically distributed sliding grooves 71, and these two sliding grooves 71 are connected as a whole. Of course, these two sliding grooves 71 can also be independent of each other, that is, they are not connected to each other. In addition, the number of the sliding grooves 71 can also be other values. For example, in the embodiments shown in Figure 13 and Figure 14 shown, the number of the sliding grooves 71 is three, and these three sliding grooves 71 are evenly distributed around the axis of the cover body 7. Correspondingly, the rotating member 3 is provided with three guiding grooves 31.

[0040] As Figure 6As shown, the groove walls of the guiding groove 31 are provided with limiting protrusions 311 for stopping the protruding posts 51 at the first position and the second position. In this way, when the cover body 7 is screwed together with or separated from the cup body 10, the protruding posts 51 can be well maintained at the corresponding work positions. For the convenience of manufacturing the rotating member 3 and facilitating the assembly of the guiding groove 31 of the rotating member 3 and the protruding posts 51 of the slider 5, in this embodiment, the column on the lower surface of the rotating member 3 is designed in a cup shape, that is, the column is a hollow structure with an open upper end. And in order to cover the opening on the upper surface of the rotating member 3, the cup cover of this embodiment further includes a fastener 1 coaxially arranged with the rotating member 3, such as Figure 6 and Figure 7 As shown, the fastener 1 has four elastic hooks evenly distributed around the axis of the rotating member 3. The rotating member 3 is provided with slot holes 32 for the elastic hooks to pass through. A clamping portion 11 (i.e., the first clamping portion) is arranged on the side of the elastic hook away from the axis of the rotating member 3. As Figure 2 and Figure 10 As shown, the side wall of the groove of the cover body 7 is provided with a clamping portion 73 (i.e., the second clamping portion) that cooperates with the clamping portion 11. During assembly, the elastic hooks of the fastener 1 pass through the slot holes 32 of the rotating member 3 and are elastically clamped on the clamping portion 73 of the cover body 7. It should be noted that the clamping portion 73 does not affect the relative rotation between the rotating member 3 and the cover body 7. For example, the clamping portion 73 can be an annular groove or a rolling rib. As Figure 8 As shown, in order to facilitate the operation of the rotating member 3, convex ribs or grooves for increasing the friction force can be arranged on the outer peripheral surface of the rotating member 3.

[0041] As Figure 1 and Figure 10 As shown, in order to enhance the anti-leakage performance, in this embodiment, a sealing ring 4 (i.e., the first sealing ring) is arranged between the outer surface of the pin body 52 and the hole wall of the through hole 72. It is easy to understand that the sealing ring 4 can be installed either on the cover body 7 or on the slider 5. For example Figure 4 As shown in the slider 5, its pin body 52 is provided with an annular groove for installing the sealing ring 4. In other embodiments, an annular groove for installing the sealing ring 4 can be provided on the hole wall of the through hole 72.

[0042] In addition, a sealing ring 2 (i.e., the second sealing ring) is arranged between the upper surface of the rotating member 3 and the fastener 1, a sealing ring 6 (i.e., the third sealing ring) is arranged between the upper surface of the cover body 7 and the rotating member 3, and a sealing ring 8 (i.e., the fourth sealing ring) is arranged on the lower surface of the cover body 7. The sealing ring 8 is used to abut against the cup mouth of the cup body 10.

[0043] The rotating member 3 is the driving member of the slider 5. By rotating the rotating member 3, the position of the slider 5 can be changed. In other embodiments, the rotating member 3 can also be omitted. For example, the position of the slider 5 can be directly toggled by hand, and the purpose of locking the filter screen 9 and the cover body 7 into one body can also be achieved. In specific practical applications, the guiding groove 31 can be either an arc-shaped groove or a straight groove, as long as it is ensured that the first position of the guiding groove 31 and the distance from the first position to the rotation center of the rotating member 3 are different. In addition, in this embodiment, the guiding groove 31 and the convex column 51 cooperate to form a cam pair. In other embodiments, the driving portion on the rotating member 3 for driving the slider 5 may not adopt the form of a groove. For example, a rib for driving the slider 5 can be provided on the rotating member 3, and a groove for cooperating with the rib can be formed on the upper surface of the slider 5, and a cam pair can also be formed.

[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
