DETAILED DESCRIPTION OF THE INVENTION

[0016] In order to facilitate understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments set forth herein. The purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0017] As shown in FIG. 1, in this embodiment, the insulated water cup with a removable and replaceable liner includes a cup body 1 and a cup cover 2. The cup body 1 has a cavity 11 formed therein, and further includes a flip-top assembly 3, a glass liner 4, an anti-collision sleeve 10, and a primary sealing ring 5. The flip-top assembly 3 is attached to the cup cover 2, and the glass liner 4 is attached to the cavity 11. The anti-collision sleeve 10 is disposed at the bottom of the cavity 11 and is used to prevent the glass liner 4 from colliding with the inner wall of the cup body 1. The primary sealing ring 5 is fitted to the outer peripheral surface of the bottom of the cup cover 2 and is used for shock absorption and buffering. Specifically, it is different from the conventional (insulated water cup) double-structure fixed water cup. Unlike a cup, in this embodiment, the cup body 1 is preferably made of stainless steel, and the split structure design allows the tea to come into contact with the glass liner 4, without affecting the quality of the tea. The cup body 1 is strong and resistant to breakage, which reduces production costs. Furthermore, a collision prevention sleeve 10 is provided between the cup body 1 and the glass liner 4, allowing the glass liner 4 to be fixedly attached relatively within the cavity of the cup body 1. The cushioning properties of the collision prevention sleeve 10 are then utilized to reduce the force of collision between the glass liner 4 and the cavity 11, reducing maintenance costs and improving safety. Furthermore, if the glass liner 4 is damaged, simply purchasing a similar glass liner 4 to replace it will allow for normal use.

[0018] Referring to FIG. 2, in this embodiment, a water outlet 21 is formed through the cup cover 2 in the vertical direction to allow water in the cup to flow out, a secondary seal ring 6 is provided at the connection between the cup cover 2 and the cup body 1 for shock absorption and buffering, a seal end 22 of the cup cover 2 is threadedly connected to the upper end opening 12 of the cup body 1 and abuts against the top end of the glass liner 4, a male thread 222 is formed on the outer peripheral surface of the middle and lower parts of the cup cover 2, and a female thread 13 that screws into the male thread 222 is formed on the inner wall surface of the top of the cavity 11 of the cup body 1. Specifically, the male thread 222 of the cup cover 2 is threadedly connected to the female thread 13 of the cavity 11 of the cup body 1, thereby realizing a detachable connection between the cup cover 2 and the cup body 1. After the glass liner 4 is assembled into the cavity 11, the sealing end 22 of the cup cover 2 is pressed into and fixed on the top of the glass liner 4 due to the threaded connection between the cup cover 2 and the cup body 1. This prevents water from leaking from the glass liner 4 even when the water cup is not positioned vertically, improving the sealing effect of the water cup.

[0019] Furthermore, a hook-shaped buffer portion 52 is formed on one end of the primary seal ring 5, an inner locking portion 53 is formed on the other end of the primary seal ring 5, and an outer locking portion 221 that engages with the inner locking portion 53 is formed on the bottom of the cup cover 2. The hook-shaped buffer portion 52 enhances the buffering properties of the primary seal ring 5, preventing excessive pressure from being generated on the glass liner 4 when the cup cover 2 is screwed in, which could cause damage to the glass liner 4 and improve safety. Next, the engagement between the inner locking portion 53 and the outer locking portion 221 allows the primary seal ring 5 to fit more stably on the cup cover 2, preventing the glass liner 4 from being completely fixed in the cavity 11 if the primary seal ring 5 is missing or falls off, increasing the risk of the glass liner 4 being damaged due to shaking of the cup body 1.

[0020] 1 and 2, the cup cover 2 is molded with vent holes 23 to balance the air pressure inside the cup after sealing. The outer periphery of the cup cover 2 is molded with limiting protrusions 24 to prevent excessive fitting with the cup body 1. The bottom of the cup body 1 is provided with an anti-slip pad 7. Specifically, the provision of the vent holes 23 on the cup cover 2 allows the user to quickly release excess air from the cavity 11 when sealing the cup body 1, reducing the feeling of claustrophobia when screwing the cup cover 2. The outer periphery of the cup cover 2 provides resistance to the upper opening 12 of the cup body 1 when the user seals and screws the cup cover 2, preventing excessive screwing from pressing against the glass liner 4 and causing unnecessary damage. The anti-slip pad 7 on the bottom of the cup body 1 increases the friction between the cup body 1 and the support surface, preventing damage caused by the water cup being dropped due to insufficient friction.

[0021] As shown in Figure 2, a handle portion 8 is further molded on one side of the cup cover 2, and the handle portion 8 is arranged in an arch shape, making it easier for the user to pick up and carry the water cup, improving the user's usage experience.In addition, the handle portion 8 is arranged in an arch shape, making it easier to connect the connecting rope (not shown) to the handle portion 8, improving user convenience.

[0022] 4, in this embodiment, the flip-top assembly 3 includes a flip-top body 31 and a sealing sleeve 32. The flip-top body 31 is formed with a sealing portion 311 that engages with the water outlet 21. By fitting the sealing sleeve 32 into the sealing portion 311 of the flip-top body 31, the sealing performance of the sealing portion 311 of the flip-top body 31 with the water outlet 21 of the cup cover 2 is improved, and the fit of the assembly is improved, resulting in reduced production costs.

[0023] 3 and 4, in this embodiment, the flip-top assembly 3 is attached to the cup cover 2, and the cup cover 2 has two symmetrically formed mounting holes 26 for attaching the flip-top assembly 3, and the other end of the flip-top body 31 has symmetrically formed hinge bumps 313 for hingedly coupling to the mounting holes 26, thereby enabling an effective connection between the flip-top assembly 3 and the cup cover 2. An inner bayonet portion 312 is formed at one end of the flip-top body 31, and the cup cover 2 has an outer bayonet portion 25 that engages with the inner bayonet portion, which improves sealing and makes the snap-on design easier for users to use.

[0024] As shown in FIG. 1 , a filter screen 9 is attached to the bottom of the primary sealing ring 5 to filter out solid matter from the glass liner 4, and a ring-shaped filter groove 51 is formed inside the bottom of the primary sealing ring 5 to accommodate the filter screen 9. The diameter of the filter screen 9 is smaller than that of the filter groove 51. Attaching the filter screen 9 to the primary sealing ring 5 can block solid matter such as tea leaves when the user is brewing tea, improving the user experience.

[0025] The above embodiments are merely preferred embodiments of the present invention and do not impose any formal limitations on the present invention.
