Description

Technical Field

[0001] The invention belongs to the technical field of water cup containers, and in particular relates to a press-linked cup cover. Background Art

[0002] Existing portable water cups are mainly divided into three categories: the first category is the most common cup lid design. This type of thermos cup can be directly drunk by opening the lid, but when drinking, the open cup mouth is easy to dissipate heat, thus affecting the insulation effect, and at the same time, the entire cup needs to be opened, which cannot be operated with one hand; the second category is the push-type, that is, a push switch is set in the center of the cup lid, and water can be discharged by pressing the push switch. Although this type of water cup is convenient to carry and can be operated with one hand, human fingers often carry a large number of bacteria. The fingers are easy to contaminate the water outlet of the push switch during the pressing process, which indirectly affects the quality of drinking water, and even the fingers are scalded during the pressing process; the third category adopts a suction nozzle design. It is difficult to pour water directly along the water outlet of this type of water cup. When using this type of thermos cup, if the suction nozzle is sucked directly, the bacteria in the human mouth are easy to contaminate the suction nozzle, and even the mouth is easy to be scalded during the sucking process. Therefore, developing a portable water cup or thermos cup that can be operated with one hand, achieves speed-increasing transmission when pressed, can quickly open the water outlet, and prevents the water outlet from being contaminated is the key point that makes this type of portable water storage container attractive to the public.

[0039] Example: Reference Figure 1-11 This embodiment mainly aims at the problems that the cup cover of the existing portable water cup cannot be operated with one hand to control the water outlet, or the manual operation easily contaminates the water outlet, and the push-link structure design is unreasonable. A push-link cup cover is proposed, such as Figure 1-3 The cup cover can be applied to a water cup or a thermos cup, and comprises a hollow cover body with a water outlet 12, the water outlet 12 is located on one side of the top surface of the cover body, a linkage assembly 30 is arranged in the cover body, the linkage assembly 30 comprises a first linkage member 32, a second linkage member 33, and a third linkage member 34 connected in sequence; a through hole 11 is opened on one side wall of the cover body, a pressing handle 31 is hinged on the outer wall of the cover body, and the pressing handle 31 can rotate relative to the cover body with the hinge point as the fulcrum; specifically, a protrusion connected in an integral manner is arranged on the side wall of the cover body, and the middle position of the pressing handle 31 is hinged to the protrusion through a first pin shaft 311. One end of the pressing handle 31 passes through the through hole 11 and is connected to one end of the linkage component 30, and the other end of the pressing handle 31 can be pressed by a finger. In the present embodiment, the pressing handle 31 is an arc-shaped plate-like structure, and the arc corresponds to the arc of the finger to improve the comfort of pressing; the other end of the linkage component 30 is connected to a sealing plug 35, and the sealing plug 35 is located at the lower end of the water outlet 12. By operating the pressing handle 31, the sealing plug 35 can be controlled to seal or open the water outlet 12.

[0040] Specifically, the cover body includes an upper shell 10 and a lower shell 20 that are detachably sealed and connected. A first sealing ring 15 made of silicone material is also provided between the upper shell 10 and the lower shell 20. The first sealing ring 15 can be used to improve the sealing performance between the upper shell 10 and the lower shell 20. The detachable connection includes a screw connection; of course, the upper shell 10 and the lower shell 20 can also be connected as one. The upper shell 10 and the lower shell 20 are detachably connected to form a hollow cavity, and the linkage assembly 30 is limited inside the cavity. A baffle plate 23 is also provided in the cavity. The baffle plate 23 separates the cover body into a first cavity and a second cavity. The water outlet 12 is connected to the second cavity, and the perforation 11 is connected to the first cavity.

[0041] Specifically, refer to Figure 7-10 As shown, one end of the pressing handle 31 penetrates through the through hole 11 and is hinged to one end of the first linkage 32 through the second pin 321, and can drive the first linkage 32 to move; since the moving trajectory of the end of the pressing handle 31 is arc-shaped, and the end of the pressing handle 31 is connected to one end of the first linkage 32, the pressing handle 31 can drive the first linkage 32 to move in an arc-shaped trajectory. The other end of the first linkage 32 is hinged to one end of the second linkage 33. In this embodiment, a first limiting hole 231 is provided on the baffle plate 23, and one end of the second linkage 33 passes through the first limiting hole 231 and is connected to one end of the first linkage 32 away from the pressing handle 31. The other end of the second linkage 33 is hinged to one end of the third linkage 34. The first limiting hole 231 can be used to limit the second linkage 33 to maintain linear movement. In a specific embodiment, a limiting slot 323 is provided at one end of the first linkage member 32 close to the second linkage member 33, a limiting shaft 331 is provided in the limiting slot 323 along the vertical direction, a second limiting hole is provided at one end of the second linkage member 33 to be clearance-matched with the limiting shaft 331, and the limiting shaft 331 can be used to convert the rotational motion of the first linkage member 32 into the linear motion of the second linkage member 33; specifically, a second limiting hole is provided at the end of the second linkage member 33 along the vertical direction, the end of the second linkage member 33 is located in the limiting slot 323, and is sleeved on the limiting shaft 331 through the second limiting hole, and can be located in the limiting slot 323 and move up and down relative to the limiting shaft 331. In a specific embodiment, a stopper 322 made of silicone material is provided near the second linkage member 33 of the first linkage member 32, and the stopper 322 can prevent excessive collision between one end of the first linkage member 32 and the baffle plate 23.

[0042] In the present embodiment, since the pressing handle 31 drives the first linkage member 32 to move in an arc-shaped trajectory, when the first linkage member 32 drives one end of the second linkage member 33 to move, the second linkage member 33 has a partial displacement in the vertical direction. In the present embodiment, the first limiting hole 231 limits the second linkage member 33 to be able to move only horizontally in a straight line, so that the rotational movement of the first linkage member 32 is converted into the linear movement of the second linkage member 33 through the clearance fit between the limiting shaft 331 and the second limiting hole. When the pressing handle 31 drives the first linkage member 32 to move, the first linkage member 32 can drive the second linkage member 33 to move in a straight line along the first limiting hole 231. In the present embodiment, the second linkage member 33 can be a rod-shaped structure.

[0043] The other end of the second linkage member 33 is hinged to one end of the third linkage member 34. The third linkage member 34 includes a first support rod 342 and a second support rod 343 connected in an integral manner at a preset angle. The preset angle can be 60° to 150°. In this embodiment, the first support rod 342 and the second support rod 343 are vertically connected. The third linkage member 34 is vertically placed inside the cover body. The inner wall of the cover body is provided with a limit plate 25 on both sides corresponding to the third linkage member 34. The limit plate 25 is vertically fixedly connected to the inner wall of the lower shell 20. The connection between the first support rod 342 and the second support rod 343 is hinged to the limit plate 25 through the third pin shaft 344 and can rotate along the hinge point. One end of the first support rod 342 is integrally connected to one end of the second support rod 343. The other end of the first support rod 342 is hinged to one end of the second linkage member 33 through the fourth pin shaft 341 and can rotate along the hinge. In this embodiment, the position of the fourth pin 341 is lower than that of the third pin 344. When the first linkage member 32 drives the second linkage member 33 to move horizontally and linearly, the second linkage member 33 can drive the third linkage member 34 to rotate along the third pin 344 through the fourth pin 341. When the sealing plug 35 closes the water outlet 12, the first support rod 342 is in a vertical state, and the second support rod 343 is in a horizontal state. The other end of the third linkage member 34 is connected with a sealing plug 35, which is located just below the water outlet 12. The sealing plug 35 is a square structure, and the upper end of the sealing plug 35 is matched with the water outlet 12. In this embodiment, a pressing hole 351 is provided on the sealing plug 35 to match the end of the second support rod 343, and one end of the second support rod 343 is located in the pressing hole 351. When the second linkage member 33 drives the third linkage member 34 to rotate along the third pin shaft 344, one end of the second support rod 343 moves downward, thereby pressing the sealing plug 35 to move downward and open the water outlet 12. In a specific embodiment, abutment 251 is further provided on one side of the limiting plate 25, and the abutment 251 can further limit the second linkage member 33 to move in the horizontal direction on the upper surface of the lower cover.

[0044] Specifically, in order to avoid the sealing plug 35 from offsetting when moving up and down, resulting in difficulty in sealing the water outlet, in this embodiment, slide grooves are provided on both sides of the sealing plug 35 in the vertical direction, and the inner wall of the cover body is provided with slide rails compatible with the slide grooves on both sides of the sealing plug 35. The third linkage member 34 drives the sealing plug 35 to move up and down along the slide rails. In this embodiment, the slide rails are reinforcing ribs integrally arranged on the inner wall of the upper shell 10, and the two sides of the slide groove cooperate with the edges of the reinforcing ribs and can move up and down along the edges of the reinforcing ribs, thereby ensuring that the sealing plug 35 can move in a straight line and accurately align with the water outlet 12.

[0045] Specifically, a first return spring 37 is provided between the lower end of the sealing plug 35 and the inner wall of the cover body, and the first return spring 37 can be used to control the sealing plug 35 to move upward. Figure 4 , Figure 5 , Figure 8 As shown, a connecting column 353 is integrally provided at the lower end of the sealing plug 35, and a fixing groove 27 is provided on the inner wall of the lower shell 20. One end of the first return spring 37 is sleeved on the connecting column 353, and the other end of the first return spring 37 is limited in the fixing groove 27. Furthermore, the first return spring 37 is a compression spring, and the sealing plug 35 is in a normally closed state. When the pressing handle 31 is pressed, the linkage assembly 30 drives the sealing plug 35 to move downward, and the first return spring 37 is in a compressed state. When the pressing handle 31 is released, the first return spring 37 is reset and pushes the sealing plug 35 upward to seal the water outlet 12, and at the same time reversely controls the linkage assembly 30 and the pressing handle 31 to reset.

[0046] In a specific embodiment, in order to further control the linkage assembly 30 and the pressing handle 31 to reset, a second reset spring 36 is provided between the end of the second linkage member 33 away from the first linkage member 32 and the baffle plate 23. The second reset spring 36 is a compression spring. Figure 2 and Fig. 9 As shown, the second return spring 36 is sleeved on the second linkage member 33, one end of the second return spring 36 abuts against one side of the baffle plate 23, and the other end of the second return spring 36 abuts against the second linkage member 33. When the pressing handle 31 is pressed, the pressing handle 31 drives the first linkage member 32 and the second linkage member 33 to move leftward, and the second linkage member 33 pulls the third linkage member 34 to rotate, and presses the sealing plug 35 downward through one end of the second support rod 343, thereby opening the water outlet 12. At this time, the first return spring 37 and the second return spring 36 are in a compressed state. When the pressing handle 31 is released, the first return spring 37 and the second return spring 36 are reset, and the linkage assembly 30, the pressing handle 31, and the sealing plug 35 are reset, thereby sealing the water outlet 12. The first return spring 37 and the second return spring 36 can make the sealing plug 35 abut tightly, further improving the anti-leakage performance.

[0047] In order to further improve the sealing performance of the sealing plug 35, in the present embodiment, a silicone sheet 38 adapted to the water outlet 12 is provided at the upper end of the sealing plug 35, a fixing column 381 is provided at the bottom surface of the silicone sheet 38, and a fixing hole 352 adapted to the fixing column 381 is provided at the upper end of the sealing plug 35. The fixing column 381 is inserted into the fixing hole 352, so that the silicone sheet 38 and the sealing plug 35 are detachably connected. At the same time, the water outlet 12 is sealed by the silicone sheet 38, which can improve the leakage-proof performance.

[0048] Specifically, the water outlet 12 is connected to the second cavity, and a water inlet 24 connected to the second cavity is opened on the lower shell 20. To further improve the sealing performance of the sealing plug 35, the first cavity and the second cavity are kept in a relatively sealed state. A second sealing ring 332 is provided between the second linkage 33 and the first limiting hole 231. The second sealing ring 332 is a silicone ring. Since the first cavity and the second cavity are connected only through the first limiting hole 231, the sealing performance of the second cavity can be further improved by setting the second sealing ring 332.

[0049] Specifically, a locking pin 40 is provided in the first cavity for resisting one side of the first linkage member 32, and the locking pin 40 is provided with a dial button 411 extending out of the side wall of the cover body. Figure 4 , Figure 5 , Figure 6 As shown, the locking pin 40 is located in the first cavity, and the edge of the first cavity is provided with an arc groove 26 adapted to the locking pin 40. The locking pin 40 is located in the arc groove 26 and can abut against one side of the first linkage member 32, thereby preventing the first linkage member 32 from moving. Furthermore, the locking pin 40 includes a resisting portion 42 and an adjusting portion 41 integrally connected to the resisting portion 42. The outer wall of the adjusting portion 41 is integrally connected with a cylindrical dial button 411. The outer wall of the upper shell 10 has an adjusting hole, and the dial button 411 passes through the cover body along the adjusting hole. By operating the dial button 411, the resisting portion 42 can be adjusted to abut against one side of the first linkage member 32. In a specific embodiment, as Figure 5 As shown, the inner wall of 26 is provided with a positioning groove 261, and the outer wall of the adjusting portion 41 is provided with an arc-shaped protrusion 43 adapted to the positioning groove 261. The number of the positioning grooves 261 in this embodiment is two. When the dial button 411 is turned to make the arc-shaped protrusion 43 cooperate with one of the positioning grooves 261, the blocking portion 42 abuts against one side of the first linkage member 32; when the dial button 411 is turned to make the arc-shaped protrusion 43 cooperate with the other positioning groove 261, the blocking portion 42 moves out from one side of the first linkage member 32.

[0050] Specifically, the outer wall of the cover body is hinged with a cap 14 adapted to the water outlet 12 through a fifth pin 141, and the cap 14 covers the water outlet 12 to ensure the hygiene of the water outlet 12. In a specific embodiment, the fifth pin 141 is also hinged with a hand frame 13, and both the cap 14 and the hand frame 13 can rotate along the fifth pin 141, and the edge of the outer wall of the upper shell 10 is also provided with a groove for accommodating the hand frame 13.

[0051] Specifically, a protective frame 21 is fixed to the side wall of the cover body corresponding to the periphery of the pressing handle 31 , and the protective frame 21 can prevent the pressing handle 31 from being pressed by accidental touching operation.

[0052] The push-linked cup cover has an ingenious and reasonable structural design. The push handle 31 and the sealing plug 35 are connected via a linkage assembly 30. The push handle 31 can be operated with one hand and transmitted via the linkage assembly 30, thereby controlling the sealing plug 35 to open or close the water outlet 12. The linkage assembly 30 is used to realize speed-increasing transmission. For example, when the push handle 31 is pressed down by 4 mm, the sealing plug 35 can move downward by 7 mm, and it can be opened with one button, which is convenient and quick.

[0053] This embodiment also proposes a water cup, which includes the above-mentioned push-linked cup cover and a hollow cylindrical cup body 50. The cup cover and the cup body 50 are detachably sealed. In this embodiment, the cup cover and the cup body 50 are threadedly connected, and a third sealing ring 22 is provided between the cup cover and the cup body 50. The third sealing ring 22 is a silicone ring; the outer wall of the cup cover is also provided with anti-slip grooves. Compared with the existing portable water cups, this water cup has good sealing performance, and at the same time avoids water leakage from the water outlet 12 or contamination of the cup cover due to repeated use, which can improve the user experience.

[0054] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
