Description

Technical Field

[0001] This utility model relates to the field of cup technology, and in particular to a thermos cup. Background Technology

[0002] Chinese utility model patent specification CN210018781U discloses a cup lid and a cup with a lid, wherein the unlocking device is located in a local recessed area of ​​the lower lid. Although it can achieve the unlocking function of sliding first and then pressing, it has the following defects: First, poor sliding stability: the space in the recessed area is narrow, and the main body of the unlocking device is restricted from sliding in the local recessed area, which can easily lead to jamming or uneven wear due to friction. Second, difficult assembly: the recessed area and the lower lid are integrally formed, and the parts need to be installed from the narrow internal space, requiring high assembly precision. Finally, insufficient drainage capacity: it is difficult to set an effective drainage channel in the recessed area, and liquid dripping or seeping in will accumulate at the bottom of the cavity, affecting its service life. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a thermos cup that not only significantly improves the stability of the sliding frame and is easy to install, but also has the advantages of preventing liquid accumulation.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A thermos cup includes a cup body, a lower lid connected to the cup body, and a flip cover with one end pivotally connected to the lower lid via a pivot. It also includes an unlocking assembly for unlocking the flip cover and the lower lid. The unlocking assembly includes an annular chamber disposed on the outer periphery of the lower lid, a buckle disposed on the other end of the flip cover with its lower end extending into the annular chamber, an opening on the outer side wall of the annular chamber corresponding to the buckle position, a sliding frame slidably connected to the annular chamber and capable of sliding radially along the lower lid with its outer end extending into the opening, a hook disposed on the sliding frame and engaging with the buckle, a stop block disposed on the annular inner wall of the annular chamber and extending into the sliding frame, and a sliding button slidably connected to the outer end of the sliding frame. When the sliding button is slid to disengage from the stop block, pressing the sliding button pushes the sliding frame radially inward along the lower lid, thereby disengaging the hook on the sliding frame from the buckle on the flip cover.

[0006] Furthermore, a first sliding groove is provided on the front side wall of the sliding frame. The first sliding groove extends axially along the pivot and has an unlocking end and a locking end. The rear end of the sliding button passes through the first sliding groove and is slidably connected to it. When the sliding button is located at the unlocking end, pressing the sliding button can push the sliding frame to move radially inward to the lower cover.

[0007] Furthermore, the through end of the sliding button is provided with a first spring post extending from the locking end toward the unlocking end, and the side wall of the sliding frame facing the first spring post is provided with a second spring post coaxially arranged with the first spring post. A first reset spring is sleeved between the first spring post and the second spring post.

[0008] Furthermore, a stop pin is provided through the through end of the sliding button, and the two ends of the stop pin protrude from the two sides of the first slide groove to prevent the sliding button from falling off the slide frame.

[0009] Furthermore, the rear end of the sliding frame has extension arms extending outward on both sides parallel to the pivot axis. Each extension arm has a second sliding groove that passes through the extension arm radially along the lower cover at both its upper and lower ends. The top and bottom walls of the annular chamber are respectively provided with slide rails that are slidably connected to the corresponding second sliding grooves.

[0010] Furthermore, the outer rear end of the sliding frame is provided with a third spring post on both sides parallel to the pivot axis. The inner side of the annular inner wall of the annular chamber is provided with a groove corresponding to each third spring post. A fourth spring post is provided in the groove and is coaxially arranged with the third spring post. A second return spring is sleeved between the third spring post and the corresponding fourth spring post.

[0011] Furthermore, the unlocking component also includes a collar, and the annular chamber is formed by the collar and the lower cover; the outer periphery of the lower cover is provided with a first flange and a second flange spaced apart vertically, and the upper and lower ends of the collar are respectively sleeved on the first flange and the second flange, and a cavity for the sliding frame to slide radially is formed between the inner sidewall of the collar and the outer wall of the lower cover.

[0012] Furthermore, the flip cover is pivotally connected to the annular cavity, and a torsion spring is sleeved on the pivot. The two torsion arms of the torsion spring abut against the flip cover and the annular cavity, respectively.

[0013] Furthermore, the top wall of the annular chamber has a through hole for the buckle to pass through, and the bottom wall of the annular chamber has a drainage hole communicating with the through hole.

[0014] Furthermore, the lower cover also has a drinking section located above it, the drinking section is provided with a drinking spout, the drinking spout is provided with a first water outlet and a second water outlet, the flip cover is a hollow cavity with an opening at the lower end, the top wall of the flip cover has a first connecting post and a second connecting post extending downward, the first connecting post and the second connecting post are respectively fitted with a first silicone sleeve and a second silicone sleeve, the first silicone sleeve and the second silicone sleeve are integrally formed, when the flip cover is closed, the first silicone sleeve and the second silicone sleeve are elastically pressed against the first water outlet and the second water outlet respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] First, the stability of the sliding frame is significantly improved: the annular chamber provides a more spacious movement space for the sliding frame, and the radial sliding of the sliding frame is guided by the cooperation of the slide rail and the second slide groove, which greatly reduces friction and uneven wear, making the sliding smoother and extending the service life.

[0017] Secondly, it is easy to install: the annular chamber is formed by the collar and the lower cover. The sliding frame, spring and other components can be pre-installed in the collar, and then the whole assembly is achieved by connecting the collar and the flange of the lower cover. There is no need to install them one by one from the narrow internal space, which simplifies the process and reduces the assembly accuracy requirements.

[0018] Third, to prevent liquid accumulation: The bottom wall of the annular chamber is equipped with a drainage hole that connects to the snap-fit ​​hole, which can quickly drain any seeping or dripping liquid, structurally solving the problem of corrosion caused by water accumulation in the recessed area and improving the product's durability.
