DETAILED DESCRIPTION

[0028] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, and those skilled in the art will appreciate that these descriptions are merely descriptive, exemplary, and should not be interpreted as limiting the protection scope of the utility model.

[0029] It should be noted that: similar signs represent similar items in the following drawings, so once an item is defined in one drawing, it can not be further defined and explained in the subsequent drawings.

[0030] This embodiment mainly describes a mistaken opening prevention tea-making thermos cup, and specifically as follows:

[0031] As Figures 1 to 8 shown, an anti-misopening tea-making thermal cup includes a cup body 1 and a cup cover 2 covering the mouth of the cup body 1. The cup cover 2 includes a connecting cover 21 and a flip cover 22 hinged to the connecting cover 21. The lower outer wall of the connecting cover 21 is provided with external threads, and the inner wall of the mouth of the cup body 1 is provided with internal threads. The lower side of the connecting cover 21 extends into the mouth of the cup body 1 and is threadedly connected to the cup body 1. This threaded connection makes the connection between the cup cover 2 and the cup body 1 more stable, effectively preventing the cup cover 2 from accidentally loosening or falling off during normal use. The connecting cover 21 has a downwardly open cavity 212 at the bottom, and a filter screen 3 is detachably arranged in the cavity 212 to block the opening of the cavity 212. The filter screen 3 and the cavity 212 form a tea bin for placing tea leaves, and the tea bin is provided with a water outlet passage 213 penetrating through the top wall of the connecting cover 21. The water outlet passage 213 is used to deliver water in the cup body 1 for the user to drink, and the flip cover 22 is provided with a blocking member 221 to block the water outlet passage 213. A locking assembly 4 is arranged between the connecting cover 21 and the flip cover 22 to lock the flip cover 22 to the connecting cover 21. By designing the cup cover 2 as the connecting cover 21 and the flip cover 22, the lower side of the connecting cover 21 is threadedly connected to the cup body 1, and the upper side is hinged to the flip cover 22. When the flip cover 22 is opened during use, the connecting cover 21 will not be opened, and when the connecting cover 21 is unscrewed, the flip cover 22 will not be opened, preventing the situation of opening one cover and mistakenly opening the other cover during use. At the same time, by designing the integrated connecting cover 21 and the detachable filter screen 3, the number of split components is reduced, the assembly is simple, the assembly efficiency is greatly improved, and the assembly complexity is reduced. During use, tea leaves are placed in the tea bin, and the connecting cover 21 is covered on the cup body 1. The cup body 1 is turned over to make the water in the cup contact and soak the tea leaves through the filter screen 3 and then separate. After the cup body 1 is placed upright, the flip cover 22 can be directly opened for drinking without disassembling the tea bin, which is very convenient to operate.

[0032] As Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the cup cover 2 further comprises a bowl cover 5 which is detachably connected on the top of the connecting cover 21, covering the flip cover 22 and the lock assembly 4 completely. The sidewall of the connecting cover 21 is provided with an annular sealing groove 214 in which an annular sealing ring 215 is sleeved; a resting platform 216 is arranged below the annular sealing groove 214, and when the bowl cover 5 is installed, the lower edge of the bowl cover 5 abuts against the resting platform 216, and the inner wall of the bowl cover 5 is in interference fit with the annular sealing ring 215, which is fixed on the connecting cover 21 by the friction between the annular sealing ring 215 and the interior of the bowl cover 5, and the sealing ring 215 effectively prevents tea and heat from leaking from the gap between the water outlet channel 213 and the blocking member 221 and overflowing from the connection between the bowl cover 5 and the connecting cover 21, improving the safety and sealing performance of the vacuum cup. The design of the bowl cover 5 protects the flip cover 22 and the lock assembly 4 from contamination, and when the bowl cover 5 is on the connecting cover 21, the lock assembly 4 is covered to prevent accidental touching of the lock assembly 4 to open the flip cover 22 by mistake, further improving the safety and reliability of the vacuum cup. When drinking tea, the bowl cover 5 can be detached and used as a separate drinking cup, improving the user experience. The connection between the bowl cover 5 and the connecting cover 21 can also be that the inner wall of the bowl cover 5 is provided with an elastic protrusion or a convex ring arranged circumferentially, and the sidewall of the connecting cover 21 is provided with an annular limiting groove, when the bowl cover 5 is covered on the connecting cover 21, the elastic protrusion extends into the annular limiting groove, and at this time the bowl cover 5 is fixed on the connecting cover 21.

[0033] As shown in Figure 2 and Figure 3 , the bottom of the water outlet channel 213 extends to the upper surface of the filter screen 3. This design ensures that when tea flows out of the water outlet channel 213, tea leaves will not enter the bowl cover 5 or stay in the water outlet channel 213, causing the water outlet channel 213 to be blocked, ensuring that tea can flow smoothly from the tea bin, improving the water outlet efficiency.

[0034] As shown in Figure 5As shown, the two side walls in the cavity 212 are provided with clamping grooves 217 extending along the circumference of the cavity 212, and the two clamping grooves 217 are provided with insertion grooves 218 extending downward to the lower end of the cavity 212 in communication with the clamping grooves 217. The side walls of the filter screen 3 are provided with protruding blocks 32 matched with the insertion grooves 218 and the clamping grooves 217. During installation, the filter screen 3 is inserted into the clamping grooves 217 from the insertion grooves 218 through the protruding blocks 32, and the protruding blocks 32 are clamped into the clamping grooves 217 when rotated, so as to quickly fix the filter screen 3 in the cavity 212. This detachable fixing mode does not require the use of tools when the filter screen 3 is disassembled and installed, and is more convenient and fast to install and disassemble, which facilitates the user to clean the filter screen 3 and replace the tea leaves, and improves the use convenience of the vacuum cup. The clamping groove 217 is provided with an elastic protruding strip 2171 arranged on the side away from the insertion groove 218. The elastic protruding strip 2171 and the side wall of the clamping groove 217 away from the insertion groove 218 form a fixing groove 2172, which is used to limit the protruding block 32. When the protruding block 32 of the filter screen 3 is rotated into the fixing groove 2172, the elastic protruding strip 2171 will hinder the protruding block 32 from sliding and cause the filter screen 3 to fall off without receiving a reverse rotating force.

[0035] Specifically, the clamping groove 217 and the insertion groove 218 on one side of the cavity 212 are centrally symmetric with the clamping groove 217 and the insertion groove 218 on the other side. This symmetrical design makes it unnecessary to consider the installation direction when the filter screen 3 is installed, further improving the installation efficiency and reducing the risk of structural instability and filter screen 3 slipping due to installation errors during use.

[0036] Specifically, the side wall of the filter screen 3 extends downward to form a disc-shaped structure with an opening downward, and the lower end of the side wall of the filter screen 3 has an outwardly extending annular table 31 along the circumference. When the filter screen 3 is fixed in the cavity 212, the lower edge of the connecting cover 21 abuts against the annular table 31. This structural design enhances the sealing performance of the filter screen 3 and the connecting cover 21, preventing tea leaves from entering the cup body 1 from the gap between the edge of the filter screen 3 and the connecting cover 21, thereby affecting the taste of tea.

[0037] Specifically, the lower surface of the filter screen 3 is provided with a handle 33. The design of the handle 33 facilitates the user to take and place the filter screen 3, especially when cleaning the filter screen 3, the user can easily take out the filter screen 3 from the cavity 212 through the handle 33, improving the user's experience.

[0038] Specifically, the top surface of the connecting cover 21 is provided with an annular water guide wall 219 extending upward to surround the water outlet of the water outlet channel 213, which is used to prevent water from splashing out when pouring water. One side of the annular water guide wall 219 is provided with a hinge joint 220, and one side of the flip cover 22 is provided with a hinge lug 227 matched with the hinge joint 220. The hinge lug 227 is hinged on the hinge joint 220 through a hinge shaft 228, and the hinge shaft 228 is provided with a torsional spring 229. One free end of the torsional spring 229 abuts against the top surface of the connecting cover 21, and the other free end abuts against the inner wall of the flip cover 22. The design of the torsional spring 229 provides the flip cover 22 with an automatic rebounding elastic force. When the locking assembly 4 between the flip cover 22 and the connecting cover 21 is opened, the flip cover 22 is quickly popped open under the action of the torsional spring 229, further improving the use convenience of the vacuum cup.

[0039] As Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the cover 22 is provided with a mounting opening 222, a limiting table 223 is arranged on the front side wall of the mounting opening 222, and a U-shaped mounting seat 224 is arranged on the bottom of the cover 22 and opens to the side of the limiting table 223, the mounting opening 222 and the U-shaped mounting seat 224 are used for mounting the lock catch assembly 4, vertical guide grooves 225 and horizontal hook grooves 226 are arranged on the two side walls of the U-shaped mounting seat 224, the lock catch assembly 4 comprises a toggle key 41 and a fixed plate 42, the toggle key 41 is provided with a front limiting plate 412 and a rear limiting plate 413 arranged in a staggered manner, first hook bodies 414 are arranged on the two sides of the side of the toggle key 41 close to the annular water guide wall 219, a toggle part 411 is formed on the top of the toggle key 41 and passes through the mounting opening 222 from the bottom surface of the cover 22, the front limiting plate 412 abuts against the upper surface of the limiting table 223, the rear limiting plate 413 abuts against the lower surface of the cover 22 away from the limiting table 223, the toggle key 41 can slide along the mounting opening 222, sliding blocks 423 are arranged on the two side walls of the fixed plate 42 and slide along the guide grooves 225, and elastic hook bodies 421 are arranged on the two side walls and cooperate with the hook grooves 226, when the fixed plate 42 slides upward along the guide grooves 225 through the sliding blocks 423, the elastic hook bodies 421 are hooked on the hook grooves 226 and support the toggle key 41, the blocking piece 221 is fixedly arranged on the fixed plate 42, a connecting column 416 is arranged on the rear side of the toggle key 41, a return spring 417 is sleeved on the connecting column 416, one end of the return spring 417 abuts against the rear side wall of the U-shaped mounting seat 224, and the other end abuts against the rear side wall of the toggle key 41, the annular water guide wall 219 is provided with a second hook body 2191 cooperating with the first hook bodies 414 to lock the cover 22. When the cover 22 is turned down and covers the connecting cover 21, under the elastic force of the return spring 417, the first hook bodies 414 are hooked on the second hook body 2191, when the toggle part 411 is pushed to slide away from the second hook body 2191, the first hook bodies 414 are disengaged from the second hook body 2191, at this time, the cover 22 is unlocked and is opened under the action of the torsional spring 229. The cooperation of the toggle key 41 and the return spring 417 makes the operation of the lock catch assembly 4 more convenient and fast.

[0040] Specifically, in order to make the toggle key 41 slide along the preset direction, a track 422 is arranged on the top surface of the fixed plate 42 and approaches the side of the first hook bodies 414 from the side close to the hinge of the cover 22, the toggle key 41 has a sliding plate 415 extending into the track 422, the sliding plate 415 can slide along the track 422 and approach or move away from the second hook body 2191, and the connecting column 416 in the above is arranged on the side of the sliding plate 415 away from the second hook body 2191.

[0041] In use, the user twists off the connecting cover 21, puts tea leaves into the tea bin (the tea bin formed by the cavity 212 and the filter screen 3), and installs the filter screen 3, then turns over the cup body 1 to soak the tea leaves after hot water is poured in.
