Description

Technical Field

[0001] The present application relates to the field of cups, and in particular to a waterproof and heat-insulating cup cover. Background Art

[0002] The cup cover is used in conjunction with the cup body to seal the water in the cup body to prevent the water from flowing out and to keep the water in the cup body warm to a certain extent. Therefore, waterproofing and heat insulation are the functions that a conventional cup cover should have.

[0003] The current connection method between the cup cover and the cup body is usually a threaded connection. When opening or closing the cup cover, one needs to hold the cup body with one hand and the cup cover with the other hand, and place the cup cover and the hand at the opening above the cup body to tighten or loosen it.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when freshly boiled water is stored inside the cup body, water vapor continues to rise. At this time, if you place your hands on the opening above the cup body to operate, your hands will be affected by the steam and feel uncomfortable as they are "steamed" locally. In addition, tightening requires aligning the threads to successfully tighten. For children, the elderly and other groups, it is sometimes necessary to repeatedly loosen and tighten the threads above the cup mouth to adjust the thread angle until they are aligned. The time spent above the cup mouth is longer, which makes it more likely to cause burns, so there is room for improvement. Summary of the invention

[0005] In order to reduce the probability of being scalded by water vapor in terms of operation, the present application provides a waterproof and heat-insulating cup cover.

[0006] The present application provides a waterproof and heat-insulating cup cover adopts the following technical solution: A waterproof and heat-insulating cup cover is used in combination with a cup body. The cup body is provided with a ball head, and the cover body is provided with a ball socket for the ball head to be inserted and rotated. An automatic box cover mechanism is provided between the cup body and the cover body, and a sealing boss is provided inside the cover body, and the sealing boss is interference fit with the opening of the cup body.

[0007] By adopting the above technical solution, during operation, the temporary lock of the automatic lid closing mechanism is released, and then the lid is flipped upward and then rotated left / right to open the lid. The connection between the lid and the cup body is set at the edge so that the entire process can be completed by one hand at the side of the cup body, without the need for both hands and without the need to place the hand directly above the cup mouth, so it is safer and more convenient.

[0008] Optionally, the cup body is provided with a positioning pin, and the cover body is provided with a positioning hole 1 and a positioning hole 2 for inserting the positioning pin, the cover body is in a closed state when the positioning pin is inserted into the positioning hole 2, and the cover body is in an open state when the positioning pin is inserted into the positioning hole 1.

[0009] By adopting the above technical solution, when the lid is closed, the positioning pin is inserted into the second positioning hole, so that the lid body is not easy to swing left and right, and the overall stability is higher during storage or carrying; when the lid is opened, the positioning pin is inserted into the first positioning hole, so that the lid body is not easy to swing left and right, and it is more stable and convenient whether drinking water or pouring water.

[0010] Optionally, the positioning pins are provided with two, namely positioning pin 1 and positioning pin 2. In the closed state, positioning pin 1 is inserted into positioning hole 1, and positioning pin 2 is inserted into positioning hole 2; There are two open states: one is that the second positioning pin is inserted into the first positioning hole; the other is that the first positioning pin is inserted into the second positioning hole; A filter plate is arranged on the inner wall of the cup body near the positioning pin.

[0011] By adopting the above technical solution, one state is that the lid is opened and then rotated to the right to finally close the lid. At this time, positioning pin 2 is inserted into positioning hole 1. At this time, if you need to drink water or pour water, it can flow out from the left side of the cup body. A filter plate is provided near the left side of the cup body (i.e., near positioning pin 1), and the filter plate is detachably connected to the cup body by magnetic adsorption. Specifically, a magnet can be buried inside the frame of the filter plate and a magnet with opposite magnetic properties can be buried inside the wall thickness of the cup body, thereby realizing magnetic adsorption of the filter plate and a specific position of the cup body. In this state, tea leaves can be intercepted by the filter plate, and thus this state is suitable for use scenarios such as drinking tea.

[0012] Another state is that the lid is opened and then turned to the left to finally close the lid. At this time, positioning pin one is inserted into positioning hole two. At this time, if you need to drink water or pour water, it can flow out from the right side of the cup body. There is no filter on this side, so this state is suitable for drinking / pouring boiled water.

[0013] A mesh cover can also be provided on the top of the filter plate, and the mesh cover and the filter plate can also be installed by magnetic adsorption, thereby forming a storage space between the side wall of the cup body, the filter plate and the mesh cover. Tea leaves can be placed in the storage space without directly soaking the tea leaves in water. The cover body can be turned left to pour out boiled water, and the cover body can be turned right to use the water flow through the storage space to brew the tea leaves and pour out the tea soup, making the structure itself more flexible.

[0014] Optionally, the filter plate is detachably connected to the cup body.

[0015] By adopting the above technical solution, it is convenient to clean or replace the filter plate.

[0016] Optionally, a sliding hole is provided inside the cover body, a slide plate is slidably inserted into the sliding hole, a sealing elastic member is provided between the sliding hole and the slide plate, and the sealing boss is connected to the slide plate.

[0017] By adopting the above technical solution, the sealing elastic member enables the sealing boss to be more tightly interference-fitted with the opening of the cup body, thereby further improving the overall sealing performance and preventing water leakage.

[0018] Optionally, the cover body is provided with a mounting seat, the side wall of the mounting seat is provided with an anti-drop block, the sealing boss is provided with a mounting hole for inserting the mounting seat, and the side wall of the mounting hole is provided with an anti-drop hole for inserting the anti-drop block.

[0019] By adopting the above technical solution, the sealing boss can be easily disassembled and assembled, thereby facilitating cleaning or replacement.

[0020] Optionally, the cup body is provided with a handle, the handle is slidably connected to a limiting plate and a limiting elastic member is provided between the handle and the limiting plate, the side wall of the cover body is provided with a pressure plate, the limiting plate abuts against the bottom of the pressure plate to limit the opening of the cover body, and the limiting elastic member is used to push the limiting plate toward the bottom of the pressure plate.

[0021] By adopting the above technical solution, the limit plate can stably support the pressure plate in the closed state, reducing the probability of accidental opening of the lid due to misoperation or accidental contact with other items in the backpack. When the lid needs to be opened, the base of the thumb is used to pull the limit plate away from under the pressure plate through static friction, and then the tip of the thumb directly presses the pressure plate and then turns it left / right. The whole process can be completed with one hand on the side of the cup body, without the need for both hands and the hand does not need to be placed directly above the cup mouth, so it is safer and more convenient.

[0022] Optionally, the top wall of the limiting plate is provided with anti-skid ridges, and the length direction of the anti-skid ridges is perpendicular to the sliding direction of the limiting plate.

[0023] By adopting the above technical solution, the friction coefficient between the fingertips in the operating room and the limit plate can be improved, making it difficult to slip out of the hand, thereby improving the stability of operation.

[0024] Optionally, the end surface of the sealing boss facing the cup body is provided with a concave area.

[0025] By adopting the above technical solution, when the lid is opened and rotated left and right by a certain angle, the concave area spans the wall thickness of the cup body, so that air can flow into the cup body from the concave area from the end away from the water outlet, thereby realizing air flow and facilitating stable water discharge from one side of the water outlet. Otherwise, for example, in a traditional thermos pot, the water outlet is also the air inlet, and the water flow of the water outlet will be disrupted by the air flow of the air intake, which may easily cause the water to flow unsmoothly.

[0026] Optionally, a plurality of guide plates are arranged in the concave area, and each of the guide plates is provided with a peak portion and a valley portion, and the peak portions of the guide plates extend into the valley portions of adjacent guide plates.

[0027] By adopting the above technical solution, the flow path of air flowing from the concave area into the cup body is more tortuous, and in an environment where the surfaces of several guide plates are humid, dust and fluff in the air are more easily adhered to the guide plates, thereby reducing the possibility of dust and fluff falling directly into the water in the cup during air circulation or reducing the amount of dust and fluff falling into the water.

[0028] 1. During operation, the root of the thumb uses static friction to pull the limit plate away from the bottom of the pressure plate, and then the tip of the thumb directly presses the pressure plate and then turns it left / right. The whole process can be completed by one hand on the side of the cup body, without the need for both hands and the hand does not need to be placed directly above the cup mouth, so it is safer and more convenient.

[0029] 2. The cup body is provided with a handle, which is slidably connected to a limit plate and a limit elastic part is provided between the handle and the limit plate. A pressure plate is provided on the side wall of the cover body, and the limit plate abuts against the bottom of the pressure plate to limit the opening of the cover body. The limit elastic part is used to push the limit plate toward the bottom of the pressure plate. When the cover is closed, the limit plate can stably support the pressure plate, reducing the probability of accidental opening of the cover due to misoperation or accidental contact with other items in the backpack. When the cover needs to be opened, the base of the thumb is used to pull the limit plate away from the bottom of the pressure plate through static friction, and then the tip of the thumb is used to press the pressure plate directly, and then turn it to the left / right. The whole process can be completed with one hand on the side of the cup body, without the need for both hands and without the need to place the hand directly above the cup mouth, so it is safer and more convenient.

[0030] 3. The end surface of the sealing boss facing the cup body is also prefabricated with a concave area. When the cover is opened and rotated left and right at a certain angle, the concave area spans the wall thickness of the cup body to allow air to flow from the concave area into the cup body to achieve air flow. A number of guide plates are arranged in the concave area. The guide plates are bent in a Z shape to form a number of peaks and valleys. The arrangement and spacing of the guide plates make the peaks of the guide plates extend into the valleys of adjacent guide plates, thereby making the flow path of the air flowing from the concave area into the cup body more tortuous. In addition, in an environment where the surfaces of the guide plates are humid, dust and fluff in the air are more likely to adhere to the guide plates, thereby reducing the possibility of dust and fluff falling directly into the water in the cup during air circulation or reducing the amount of dust and fluff falling into the water.

[0033] The following is combined with Figure 1-10 This application is described in further detail.

[0034] The present application embodiment discloses a waterproof and heat-insulating cup cover. Figure 1 The waterproof and heat-insulating cup cover comprises a cover body 1 used in conjunction with a cup body 2. A handle 3 is arranged on the side wall of the cup body 2. The handle 3 is connected to the cup body 2 only at the bottom and at the top. The top of the handle 3 has a notch and there is a gap between the cover body 1 and the cup body 2. The cover body 1 is movably connected to the cup body 2 and a pressing plate 11 is integrally formed at the edge of the cover body 1. The pressing plate 11 is located at the notch at the top of the handle 3. When in use, the cover body 1 can be opened by holding the handle 3 with one hand and pressing the plate 11 downward with the thumb. The operation is convenient, and the user will not be affected by the "steaming feeling" of water vapor at the mouth of the cup, and will not be easily scalded.

[0035] Reference Figures 2 to 4A ball head 21 is fixedly provided on the top wall of the cup body 2, and a ball socket 210 is provided on the cover body 1. The diameter of the ball head 21 is larger than the diameter of the opening of the ball socket 210. The ball head 21 is installed inside the ball socket 210 by interference fitting, so that the cover body 1 and the cup body 2 can be movably connected, so that the cover body 1 can be turned upside down and rotated left and right relative to the cup body 2. An automatic box cover mechanism is provided between the cup body 2 and the cover body 1. The automatic cover closing mechanism 4 can be various elastic structures such as springs and elastic ropes. In this embodiment, the automatic cover closing mechanism 4 is a torsion spring, which is fixedly provided with the cup body 2 and has two ends respectively abutting against the side wall of the cup body 2 and the pressure plate 11, so as to push the pressure plate 11 up, thereby making the cover body 1 have a tendency to automatically close the cover.

[0036] Reference Figure 4 A sliding hole 120 is provided inside the cover body 1. The sliding hole 120 is a circular hole and is coaxially arranged with the cover body 1. A slide plate 12 is slidably inserted in the sliding hole 120. The slide plate 12 is a circular plate adapted to the sliding hole 120. A sealing elastic member 13 is provided between the sliding hole 120 and the slide plate 12. The sealing elastic member 13 is an elastic member such as rubber or a spring. In this embodiment, a spring is selected and fixed by bonding. A mounting seat 14 is bonded to the bottom of the slide plate 12. The mounting seat 14 is cylindrical and coaxially arranged with the slide plate 12 and has a smaller diameter than the slide plate 12. An anti-slip block 15 is integrally formed on the side wall of the mounting seat 14. A sealing boss 5 is provided below the slide plate 12, a mounting hole 140 is provided on the top of the sealing boss 5, and an anti-drop hole 150 is provided on the side wall of the mounting hole 140. The mounting seat 14 can be installed into the mounting hole 140 and the anti-drop block 15 is adapted to be inserted into the anti-drop hole 150 after the installation is completed, thereby completing the installation of the sealing boss 5 and the cover body 1, and subsequent replacement is also relatively convenient.

[0037] Reference Figure 4 The notch at the top of the handle 3 is slidably connected to a limiting plate 31, and a limiting elastic member 32 is glued and fixed between the handle 3 and the limiting plate 31. In this embodiment, the limiting elastic member 32 adopts a spring to push the fiberboard toward the direction of the pressing plate 11. The end of the limiting plate 31 close to the pressing plate 11 has a guide surface for more conveniently entering under the pressing plate 11 to support the bottom of the pressing plate 11 and thereby limit the pressing plate 11 from rotating downward, that is, limit the opening of the cover 1, thereby reducing the probability of accidental opening of the cover 1 due to misoperation or accidental contact with other items in the backpack. In addition, a plurality of anti-slip ridges 33 are integrally formed on the top wall of the limiting plate 31, and the arrangement direction of the plurality of anti-slip ridges 33 is arranged parallel to the sliding direction of the limiting plate 31, and the length direction of the plurality of anti-slip ridges 33 themselves is arranged perpendicular to the sliding direction of the limiting plate 31.

[0038] Reference Figure 4 and Figure 5The end surface of the sealing boss 5 facing the cup body 2 is also prefabricated with a concave area 50. When the cover body 1 is opened and rotated left and right by a certain angle, the concave area 50 spans the wall thickness of the cup body 2, so that air can flow from the concave area 50 into the cup body 2 to achieve air flow. A number of guide plates 51 are arranged in the concave area 50. The guide plates 51 are bent in a Z shape to form a number of peaks 511 and valleys 512. The arrangement and spacing of the guide plates 51 make the peaks 511 of the guide plates 51 extend into the valleys 512 of the adjacent guide plates 51, thereby making the flow path of the air flowing from the concave area 50 into the cup body 2 more tortuous. In addition, in the environment where the surfaces of the guide plates 51 are humid, the dust and fluff in the air are more likely to adhere to the guide plates 51, thereby reducing the possibility of dust and fluff falling directly into the water body in the cup during air circulation or reducing the amount of dust and fluff falling into the water body.

[0039] Reference Figure 6 The top of the cup body 2 is also integrally formed with a positioning pin 1 61 and a positioning pin 2 62, which have the same shape and size. Correspondingly, the bottom of the cover body 1 is provided with a positioning hole 1 610 and a positioning hole 2 620, which have the same shape and size. When the cover is closed, the positioning pin 1 61 is inserted into the positioning hole 1 610, and the positioning pin 2 62 is inserted into the positioning hole 2 620, so that the cover body 1 is not easy to rotate left and right when the cover is closed.

[0040] The open state is divided into two situations to suit different groups of people or different demand scenarios: Reference Figure 7 , one state is that the cover body 1 is opened and then turned to the right to finally close the cover, at which time the positioning pin 2 62 is inserted into the positioning hole 1 610, and water can flow out from the left side of the cup body 2 when it is needed to drink or pour water. A filter plate 22 is provided at a position close to the left side of the cup body 2 (i.e., close to the positioning pin 1 61), and the filter plate 22 is detachably connected to the cup body 2 by magnetic adsorption. Specifically, a magnet can be buried inside the frame of the filter plate 22 and a magnet with opposite magnetic properties can be buried inside the wall thickness of the cup body 2, thereby realizing magnetic adsorption of the filter plate 22 and a specific position of the cup body 2. In this state, tea leaves can be intercepted by the filter plate 22, and this state is suitable for use scenarios such as drinking tea. A mesh cover 23 can also be provided on the top of the filter plate 22, and the mesh cover 23 and the filter plate 22 can also be installed by magnetic adsorption, thereby forming a holding space between the side wall of the cup body 2, the filter plate 22 and the mesh cover 23, and tea leaves are placed in the holding space without directly soaking the tea leaves in water.

[0041] Reference Figure 8Another state is that the cover body 1 is opened and then rotated to the left to finally close the cover. At this time, the positioning pin 1 61 is inserted into the positioning hole 2 620. At this time, if you need to drink water or pour water, it can flow out from the right side of the cup body 2. There is no filter on this side, so this state is suitable for the use scenario of drinking / pouring boiled water.

[0042] The cover body 1 can be rotated to the left to pour out boiled water, and can also be rotated to the right to brew tea leaves through the accommodating space and pour out tea soup, making the structure itself more flexible.

[0043] The implementation principle of a waterproof and heat-insulating cup cover in an embodiment of the present application is as follows: during operation, the root of the thumb uses static friction to pull the limit plate 31 away from under the pressure plate 11, and then the tip of the thumb directly presses the pressure plate 11 and then rotates it to the left / right. The entire process can be completed with one hand on the side of the cup body 2, without the need for both hands and without the need to place the hand directly above the cup mouth, so it is safer and more convenient.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
