[0053] An outer cover 20a adapted to the cup body 10a, the inner wall of the top of the outer cover 20a protrudes downward to form a card frame 21a, the inner wall of the card frame 21a is formed with a card slot 210, and the bottom end of the card frame 21a is formed with a notch 211a connected to the card slot 210a; and

[0054] An inner plug 30a is vertically arranged in the outer cover 20a, and the top of the inner plug 30a is inserted in the card frame 21a. A card block 33a is formed on the top of the outer wall of the inner plug 30a. The card block 33a is inserted in the card slot to realize the limited connection between the inner plug 30a and the outer cover 20a; by rotating the inner plug 30a, the card block 33a is driven to rotate from the card slot 210a to the notch 211a and detach from the card slot 210a through the notch, thereby separating the inner plug 30a and the outer cover 20a.

[0055] The inner plug and the outer cover of the present invention can be detached and separated into separate parts, which are convenient for cleaning and installation, thereby solving the problem in the prior art that the cup cover is easy to accumulate dirt and is difficult to disassemble and clean.

[0056] As a preferred embodiment of the detachable and washable cup cover of the present invention, the interior of the inner plug 30a is hollow, the top of the inner plug 30a is open and the bottom is closed by the bottom plate, and the bottom plate is provided with an exhaust hole; the top of the outer cover 20a is provided with a through hole connected to the inner plug 30a; it also includes an exhaust valve 70a, the exhaust valve 70a is outer-circuited with a second spring 72a, the exhaust valve 70a is inserted in the inner plug 30a through the through hole and protrudes out of the exhaust hole, the second spring 72a is connected between the top of the exhaust valve 70a and the bottom plate, and the bottom end of the exhaust valve 70a is sleeved with a sealing ring 71a, the sealing ring 71a blocks the exhaust hole, and by pressing the exhaust valve 70a to move downward, the sealing ring 71a is driven to move downward to disengage from the exhaust hole to open the exhaust hole; the exhaust valve 70a is released and pressed, and the exhaust valve 70a is moved upward and reset under the action of the second spring 72a.

[0057] When the cup is filled with hot water, it expands and contracts as the temperature drops, and the external atmospheric pressure is significantly higher than the internal pressure of the cup, there is a pressure difference between the inside and outside of the cup, and the lid is difficult to open. By setting the exhaust valve 70a, pressing the exhaust valve 70a downward, the sealing ring 71a is driven to separate from the exhaust hole, thereby opening the exhaust hole, so that the air pressure inside and outside the cup is balanced, making it easy to open the cup lid.

[0058] Specifically, the exhaust valve 70a is a cylindrical rod, and the diameter of the exhaust hole of the bottom plate is slightly larger than the outer diameter of the bottom end of the exhaust valve 70a. After the exhaust valve 70a moves downward, the sealing ring 71a is driven to separate from the exhaust hole to open the exhaust hole for exhaust, which also facilitates the insertion and up and down movement of the exhaust valve 70a.

[0059] The sealing ring 71a is a silicone sleeve sleeved on the bottom end of the exhaust valve 70a, and the gap between the exhaust valve 70a and the bottom plate is blocked by the silicone sleeve to prevent leakage.

[0060] Furthermore, a sleeve corresponding to the exhaust hole is fixed on the upper side of the bottom plate, and the exhaust valve 70a passes through the sleeve and is in contact with the inner wall of the sleeve, thereby playing a role of leak prevention and guidance.

[0061] As a preferred embodiment of the detachable and washable cup cover of the present invention, the top of the exhaust valve 70a is formed with a cap edge protruding from the exhaust valve 70a, which is used to limit the top of the second spring 72a, and the bottom of the second spring 72a abuts against the sleeve on the upper side of the bottom plate for limiting. When the exhaust valve 70a is pressed downward, the second spring 72a is compressed, and after the pressure is released, the exhaust valve 70a moves upward and resets under the elastic action of the second spring 72a.

[0062] As a preferred embodiment of the detachable and washable cup cover of the present invention, it also includes a button 22a provided at the through opening and spliced ​​with the outer cover 20a, and the button 22a covers the top of the exhaust valve 70a; the edge of the button 22a obliquely protrudes downward to form a limiting ring, and the limiting ring is blocked on the top inner wall of the outer cover 20a, and the top surface of the button 22 is flush with the top surface of the outer cover 20a. The button 22a is blocked on the top inner wall of the outer cover 20a by the limiting ring on the edge to limit the button 22a and prevent the button 22a from falling. The button 22a is made of flexible material and can be deformed by pressing, thereby pressing the exhaust valve 70a.

[0063] As a preferred embodiment of the detachable and washable cup cover of the present invention, the outer cover 20a is sleeved on the top of the cup body 10a and covers the cup mouth; the inner plug 30a is inserted into the cup body 10a through the cup mouth; a circle of waterproof ribs is fixed to the inner wall of the cup body 10a; when the outer cover is covered on the cup body 10a, the elastic leak-proof sleeve 60a is tightly attached to the waterproof ribs and can be elastically deformed to seal the gap between the inner wall of the cup body 10 and the contact surface of the inner plug 30a to avoid leakage.

[0064] As a preferred embodiment of the detachable and washable cup cover of the present invention, a cup mouth sleeve 80a is sleeved on the top of the cup body 10a, and a protrusion 81a is formed on the outer wall of the cup mouth sleeve 80a; a groove adapted to the protrusion 81a is formed on the inner wall of the outer cover 20a, and the bottom side wall of the groove extends obliquely downward to the bottom end of the outer cover 20a; when the outer cover 20a is sleeved on the top of the cup body 10a, the protrusion 81a is moved along the bottom side wall of the groove to be inserted into the groove for fixed connection by rotating the outer cover 20a.

[0065] Furthermore, the bottom of the inner plug 30a is sleeved with an elastic leak-proof sleeve 60a. Specifically, there are at least four protrusions 81a, which are arranged at intervals on the outer wall of the cup mouth sleeve 80a. By pressing the outer cover 20a with force and rotating it 45°, the protrusion 81a is moved along the bottom side wall of the groove to be inserted into the groove. The elastic leak-proof sleeve 60a is tightly attached to the waterproof rib, which not only prevents water seepage, but also generates an upward reaction force, so that the outer cover has an overall upward force, so that the protrusion 81a is tightly attached to the groove of the outer cover 20a, achieving the effect of locking the cover; to open the cover, just press the outer cover 20a downward with force and rotate it, so that the protrusion 81a moves along the bottom side wall of the groove and drives out of the groove, and the outer cover 20a and the cup body 10a can be separated, avoiding the operation of rotating the outer cover 20a several times to open the outer cover through the thread design in the prior art.

[0066] Furthermore, a horizontal support plate is formed on the cup body 10a for supporting the bottom end of the outer cover 20a. After the outer cover 20a is covered on the cup body 10a, the outer cover 20a and the side wall of the cup body 10 are flush with each other, and the whole is beautiful.

[0067] The present invention also provides a method for disassembling a detachable and washable cup cover, comprising the following steps:

[0068] The inner plug 30a and the outer cover 20a are rotated relative to each other, so as to drive the clamping block 33a to rotate from the clamping slot to the notch; and

[0069] The inner plug 30a is moved toward the bottom end of the outer cover 20a, driving the clamping block 33a to move out of the notch to disengage from the clamping groove, thereby separating the inner plug 30a and the outer cover 20a.

[0070] The detachable and washable cup cover of the present invention also includes a second embodiment. Figure 8 It is a schematic diagram of an exploded view of a second embodiment of the detachable and washable cup cover of the present invention. Fig. 9 This is a diagram of the outer cover of the second embodiment of the detachable and washable cup cover of the present invention. Fig.10 and Fig.11 It is a cross-sectional view and a side-sectional view of a second embodiment of the detachable and washable cup cover of the present invention, in which the cover is arranged on the cup body. Fig.12 and Fig.13 The cross-sectional view and side-sectional view of the second embodiment of the present invention in which the detachable and washable cup cover is separated from the cup body. Figures 9 to 13As shown, the inner plug 30 is hollow inside, and a vertical groove is formed on the side wall of the inner plug 30. The inner plug 30 also includes a lock 40 vertically arranged in the vertical groove and hinged to the inner plug 30. The lock 40 can rotate around the hinge, and the top of the lock 40 corresponds to the inner wall of the card frame 21; a first spring 50 connected to the bottom of the lock 40 at one end, and the other end of the first spring 50 points to the inside of the inner plug 30 and is connected to the inner plug 30; and an elastic leak-proof sleeve 6 sleeved on the bottom of the inner plug 30 and corresponding to the bottom of the vertical groove 0, the elastic leak-proof sleeve 60 is bound to the bottom of the lock member 40, driving the lock member 40 to rotate around the hinge so that the top end of the lock member 40 is supported on the inner wall of the card frame 21, thereby preventing the inner plug 30 and the outer cover 20 from rotating relative to each other; by separating the elastic leak-proof sleeve 60 from the inner plug 30 to release the binding on the lock member 40, the lock member 40 rotates around the hinge under the action of the first spring 50, driving the top end of the lock member 40 to separate from the card frame 21, so that the inner plug 30 and the outer cover 20 can rotate relative to each other.

[0071] Furthermore, the present invention hinges a lock piece on the side wall of the inner plug, and uses an elastic leak-proof sleeve to cover the inner plug to press and restrain the bottom of the lock piece, so that the top of the lock piece can rotate outward around the hinge. When the top of the inner plug is inserted into the card frame of the outer cover, the top of the lock piece is supported on the inner wall of the card frame of the outer cover to limit the connection between the lock piece and the outer cover, thereby preventing the inner plug and the outer cover from being accidentally rotated relative to each other and accidentally disassembled.

[0072] By separating the elastic leak-proof sleeve from the inner plug to release the pressing restraint on the lock, the lock rotates around the hinge under the action of the first spring, driving the top of the lock to separate from the inner wall of the card frame, so that the inner plug and the outer cover can rotate relatively. By relatively rotating the inner plug and the outer cover, the card block is driven to rotate from the card slot to the notch and separate from the card slot through the notch, and the inner plug can be taken out. The inner plug and the outer cover of the present invention can be detached and separated into separate parts, which is convenient for cleaning and installation. Therefore, the present invention solves the problem that the cup cover in the prior art is easy to accumulate dirt and difficult to disassemble and clean.

[0073] As a preferred embodiment of the detachable and washable cup cover of the present invention, the inner plug 30 is open at the top and closed at the bottom by a bottom plate, and an exhaust hole is provided on the bottom plate; a through hole connected to the inner plug 30 is provided at the top of the outer cover 20; and an exhaust valve 70 is also included, and a second spring 72 is provided on the outer sleeve of the exhaust valve 70. The exhaust valve 70 is inserted in the inner plug 30 through the through hole and protrudes out of the exhaust hole, and the second spring 72 is connected between the top end of the exhaust valve 70 and the bottom plate, and a sealing ring 71 is provided on the bottom end of the exhaust valve 70, and the sealing ring 71 is sealed in the exhaust hole. By pressing the exhaust valve 70 to move downward, the sealing ring 71 is driven to move downward to disengage from the exhaust hole to open the exhaust hole; the exhaust valve 70 is released and pressed, and the exhaust valve 70 moves upward and resets under the action of the second spring 72.

[0074] When the cup is filled with hot water, it expands and contracts as the temperature drops, and the external atmospheric pressure is significantly higher than the internal pressure of the cup, there is a pressure difference between the inside and outside of the cup, and the lid is difficult to open. By setting the exhaust valve 70, pressing the exhaust valve 70 downward, the sealing ring 71 is driven to separate from the exhaust hole, thereby opening the exhaust hole, so that the air pressure inside and outside the cup is balanced, making it easy to open the cup lid.

[0075] Specifically, the exhaust valve 70 is a cylindrical rod, and the diameter of the exhaust hole of the bottom plate is slightly larger than the outer diameter of the bottom end of the exhaust valve 70. After the exhaust valve 70 moves downward, the sealing ring 71 is driven to separate from the exhaust hole to open the exhaust hole for exhaust, which also facilitates the insertion and up and down movement of the exhaust valve 70.

[0076] The plugging ring 71 is a silicone sleeve sleeved on the bottom end of the exhaust valve 70. The silicone sleeve blocks the gap between the exhaust valve 70 and the bottom plate to prevent leakage.

[0077] Furthermore, a sleeve corresponding to the exhaust hole is fixed on the upper side of the bottom plate, and the exhaust valve 70 passes through the sleeve and is in contact with the inner wall of the sleeve, thereby playing a role of leak prevention and guidance.

[0078] As a preferred embodiment of the detachable and washable cup cover of the present invention, the top of the exhaust valve 70 is formed with a cap brim protruding from the exhaust valve 70, which is used to limit the top of the second spring 72. The bottom end of the second spring 72 abuts against the sleeve on the upper side of the bottom plate for limiting. When the exhaust valve 70 is pressed downward, the second spring 72 is compressed. After the pressure is released, the exhaust valve 70 moves upward and resets under the elastic action of the second spring 72.

[0089] The elastic leak-proof sleeve 60 is separated from the inner plug 30 to release the restraint on the lock 40, so that the inner plug 30 and the outer cover 20 can rotate relative to each other;

[0090] The inner plug 30 and the outer cover 20 are rotated relative to each other, so as to drive the clamping block 33 to rotate from the clamping groove to the notch; and

[0091] The inner plug 30 is moved toward the bottom end of the outer cover 20 to drive the clamping block 33 to move out of the notch to disengage from the clamping groove, thereby separating the inner plug 30 and the outer cover 20 .

[0092] The beneficial effects of the detachable and washable cup cover and the disassembly method thereof of the present invention are as follows:

[0093] The present invention forms a card slot on the inner wall of the card frame of the outer cover, and forms a notch connected to the card slot at the bottom end of the card frame. The top of the inner plug is inserted into the card frame, and the card block of the inner plug is inserted into the card slot to realize the limited connection between the inner plug and the outer cover; by rotating the inner plug, the card block is driven to rotate from the card slot to the notch and detach from the card slot through the notch, thereby separating the inner plug and the outer cover.

[0094] Furthermore, the present invention hinges a lock piece on the side wall of the inner bolt, and uses an elastic leak-proof sleeve to cover the inner bolt to press and restrain the bottom of the lock piece, so that the top of the lock piece can rotate outward around the hinge. When the top of the inner bolt is inserted into the card frame of the outer cover, the top of the lock piece is supported on the inner wall of the card frame of the outer cover to limit the connection between the lock piece and the outer cover, thereby preventing the inner bolt and the outer cover from accidentally rotating and being disassembled.

[0095] By separating the elastic leak-proof sleeve from the inner plug to release the pressing restraint on the lock, the lock rotates around the hinge under the action of the first spring, driving the top of the lock to separate from the inner wall of the card frame, so that the inner plug and the outer cover can rotate relatively. By relatively rotating the inner plug and the outer cover, the card block is driven to rotate from the card slot to the notch and separate from the card slot through the notch, and the inner plug can be taken out. The inner plug and the outer cover of the present invention can be detached and separated into separate parts, which is convenient for cleaning and installation. Therefore, the present invention solves the problem that the cup cover in the prior art is easy to accumulate dirt and difficult to disassemble and clean.

[0096] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
