Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of water cups, and particularly relates to a cup cover with a detachable suction nozzle. BACKGROUND

[0002] The existing cup cover with a suction nozzle usually has the suction nozzle rotationally arranged on the cup cover body of the cup cover, and the suction nozzle is switched between a sealing position and a drinking position through rotation. For specific structures, refer to the Chinese Utility Model Patent with the Patent No. CN214803963U and the like. Most of the existing suction nozzle cup covers cannot be disassembled or are difficult to disassemble, which makes cleaning inconvenient or incomplete.

[0003] To solve the problem of disassembly of the suction nozzle, the Chinese Utility Model Patent with the Patent No. CN206910177U discloses a cup cover with a detachable suction nozzle, which comprises a cup cover body, the upper surface of the cup cover body is provided with a cavity recessed into the cup cover body, the two side walls of the cavity are both provided with a hinge shaft, and the cavity is provided with a suction nozzle. The suction nozzle comprises a spherical joint and a columnar part which are integrally formed, a hinge shaft sleeve is arranged in the center through hole of the spherical joint, the hinge shaft sleeve is composed of two half sleeves which are placed opposite to each other and have a working gap reserved therebetween, the half sleeve is provided with a space for the hinge shaft, the hinge shaft is slid into the space in the half sleeve through the working gap reserved, the hinge shaft and the cup cover body are hinged, a suction hole is arranged in the columnar part, the suction hole is communicated with the body through a suction pipe, and the upper and lower surfaces of the columnar part are respectively provided with a pressing plate and a convex column. The Chinese Utility Model Patent with the Patent No. CN209346579U discloses another disassembly structure of the suction nozzle, an axle hole is formed in the cup cover body, a rotating shaft is formed on the suction nozzle, the rotating shaft is clamped into the axle hole in the radial direction, and the rotating shaft and / or the cup cover body are deformed to make the rotating shaft come out of the axle hole.

[0004] The schemes of the Utility Models CN206910177U and CN209346579U both realize the disassembly of the suction nozzle, and the structures are relatively simple. However, in the two schemes, the suction nozzle is directly disassembled and connected with the cup cover body, and the reliability is low, which is mainly manifested in the following aspects: in order to ensure sealing, the silicone sealing element needs to be deformed enough, which makes the stress at the connection between the suction nozzle and the cup cover body cannot be too small; in order to make the suction nozzle easy to pull out, the deformation between the suction nozzle and the cup cover body cannot be too large. The two requirements have opposite requirements for the connection between the suction nozzle and the cup cover body, which makes it difficult for the existing structure to meet both requirements, and the reliability is low. When there is a machining error or after being used for a period of time, the problem is more serious. SUMMARY

[0005] In view of the low reliability of the disassembly structure of the suction nozzle of the existing suction nozzle cup cover, the present application provides a cup cover with a detachable suction nozzle, improves the disassembly structure of the suction nozzle, meets the requirements of sealing and disassembly, and improves the reliability of the structure.

[0006] To achieve the above object, the application adopts the following technical scheme: a detachable cup cover with a suction nozzle, comprising:

[0007] An outer cover with a sealing installation groove, a suction nozzle installation groove and a lock installation groove;

[0008] A silica gel sealing element installed in the sealing installation groove of the outer cover, with a water outlet hole and an air inlet hole;

[0009] A suction nozzle installed in the suction nozzle installation groove of the outer cover;

[0010] A lock assembly installed in the lock installation groove of the outer cover;

[0011] The silica gel sealing element is installed vertically in the sealing installation groove, the suction nozzle is installed obliquely in the suction nozzle installation groove, the lock assembly is installed horizontally in the lock installation groove, the lock assembly is connected with the outer cover, and the lock assembly forms a lock-out part to prevent the suction nozzle from being pulled out.

[0012] The detachable cup cover with a suction nozzle of the application has the sealing installation groove, the suction nozzle installation groove and the lock installation groove in the outer cover, and the silica gel sealing element, the suction nozzle and the lock assembly are installed in the outer cover in sequence, and the lock assembly prevents the suction nozzle from being pulled out. Since the lock assembly is added, the lock assembly needs to be removed before the suction nozzle is removed during cleaning, which is more reliable and ensures the sealing.

[0013] As an improvement, the suction nozzle installation groove includes a long groove and an arc-shaped hole formed in the side wall of the long groove, and the suction nozzle includes a main body part and a shaft part, the main body part is located in the long groove, and the shaft part is located in the arc-shaped hole. An attraction hole is formed in the main body part, and an operation part is formed on the main body part.

[0014] As an improvement, the lock installation groove includes a horizontal groove, the outer end of the horizontal groove is open, and the inner end is communicated with the arc-shaped hole. The horizontal groove is used for the installation of the lock assembly and the installation of the suction nozzle.

[0015] As an improvement, the lock installation groove further includes a U-shaped groove with a U-shaped horizontal projection. The U-shaped groove includes a part located above the horizontal groove and a part located at the outer end of the horizontal groove.

[0016] As an improvement, the side wall of the horizontal groove extends to form an upper lock-out block, and the lock assembly has a lower lock-out block matched with the upper lock-out block. The cooperation of the upper lock-out block and the lower lock-out block prevents the lock assembly from being pulled out vertically.

[0017] As an improvement, the lock-out part includes an upper arc-shaped part with the same diameter as the arc-shaped hole and a lower vertical part.

[0018] As an improvement, the angle of the arc-shaped hole is greater than 180°, and the upper end of the arc-shaped hole is further outward than the highest point thereof. With such an arrangement, the arc-shaped hole provides support for the rotation of the mouthpiece without disassembly, rather than the locking assembly.

[0019] As an improvement, the sealing installation groove is formed in the bottom wall of the long groove.

[0020] As an improvement, the silica gel sealing piece is a one-piece. In other solutions, the silica gel sealing piece can also be two separate pieces.

[0021] As an improvement, the silica gel sealing piece has two clamping positions with the outer cover, corresponding to the water outlet hole and the air inlet hole, respectively.

[0022] As an improvement, the outer cover has an internal thread.

[0023] As an improvement, the locking assembly forms a limiting portion that limits the rotation angle of the mouthpiece. When the locking assembly is present, the maximum rotation angle of the mouthpiece is limited by the locking assembly, and when the mouthpiece cup locking assembly is limited, it is also the drinking angle.

[0024] As an improvement, the locking installation groove is adapted to the shape of the locking assembly. The upper surface of the locking assembly is substantially flush with the upper end surface of the outer cover, and the vertical outer surface of the locking assembly is substantially flush with the outer cover. There is no gap between the locking assembly and the outer cover.

[0025] As an improvement, the horizontal projection of the locking assembly is generally U-shaped, which is suitable for the mouthpiece and also facilitates the operation of the locking assembly.

[0026] As an improvement, the locking assembly includes a locking piece and a sliding piece that can be lifted relative to the locking piece. The inner side of the sliding piece forms a clamping groove, and the outer cover forms a clamping block that can cooperate with the clamping groove. When the sliding piece is in the lower locked position, the clamping block is clamped into the clamping groove; when the sliding piece is in the higher unlocked position, the clamping block is disengaged from the clamping groove. The locking assembly uses a locking piece and a sliding piece to prevent the locking assembly from being horizontally removed by cooperating the sliding piece with the outer cover.

[0027] As an improvement, a positioning structure is formed between the sliding piece and the locking piece, and the sliding piece is positioned relative to the locking piece when the sliding piece is in the locked position. The sliding piece and the locking piece form a positioning structure to prevent the sliding piece from sliding relative to the locking piece at will. The positioning structure can be a horizontal positioning groove formed on the sliding piece and a horizontal positioning strip formed on the locking piece. Among them, the positioning groove has two, corresponding to the locked position and the unlocked position, respectively.

[0028] As an improvement, a state indicating mark is formed on the locking piece.

[0029] As an improvement, the slide is clamped with the lock catch, a horizontal clamping part is formed on the slide, the clamping groove is opened on the clamping part, and the lock catch forms a rectangular groove clamped with the clamping part.

[0030] The detachable cup cover with a suction nozzle has the following advantages: the outer cover is provided with a sealing installation groove, a suction nozzle installation groove and a lock catch installation groove, a silica gel sealing element, a suction nozzle and a lock catch assembly are sequentially installed on the outer cover, the lock catch assembly prevents the suction nozzle from being pulled out, the lock catch assembly is removed before the suction nozzle is removed when cleaning is needed, better reliability is achieved, and the sealing can be guaranteed.

[0076] In the embodiment, the lock assembly 4 comprises a lock piece 41 and a slide 42 which can be lifted relative to the lock piece 41, and a clamping groove 423 is formed in the inner side of the slide 42. A clamping block 15 is formed on the outer cover 1 and can cooperate with the clamping groove 423. When the slide 42 is in the lower locked position, the clamping block 15 is clamped into the clamping groove 423. When the slide 42 is in the higher unlocked position, the clamping block 15 is disengaged from the clamping groove 423. The lock assembly 4 uses the lock piece 41 and the slide 42, and the cooperation between the slide 42 and the outer cover 1 prevents the lock assembly 4 from being horizontally pulled out.

[0077] In the embodiment, a positioning structure is formed between the slide 42 and the lock piece 41. When the slide 42 is in the locked position, the slide 42 is positioned relative to the lock piece 41. The slide 42 and the lock piece 41 form a positioning structure to prevent the slide 42 from sliding relative to the lock piece 41 at will. The positioning structure can be a horizontal positioning groove 421 formed on the slide 42 and a horizontal positioning bar 412 formed on the lock piece 41. The positioning groove 421 has two, corresponding to the locked position and the unlocked position.

[0078] In the embodiment, a state indicating mark 413 is formed on the lock piece 41. The state indicating mark 413 comprises a concave-convex formed locked mark and a concave-convex formed unlocked mark.

[0080] In the embodiment, the lock piece 41 is provided with a sliding groove, and the slide 42 has a sliding portion which is guided by the sliding groove. The sliding groove is arranged at a small angle to the vertical surface and is inclined upward. A through groove is formed on the wall of the sliding groove which is close to the vertical surface, and the through groove forms the clamping groove 423. A finger operating portion is formed on the upper part of the lock piece 41 for operation.

[0081] In the embodiment, the outer cover 1 is further provided with a sealing ring 5, and the outer cover 1 has an internal thread. An external thread is formed on the cup body, and the outer cover 1 is screwed with the cup body through the internal thread and the external thread. The sealing ring 5 seals the outer cover 1 and the cup body.

[0082] In the embodiment, the outer cover 1 is further provided with a handle 6 which is clamped with the outer cover 1.

[0083] In this embodiment, the assembly process of the suction nozzle 3 is as follows: First, the silicone seal 2 is vertically installed into the sealing mounting groove 11 of the outer cover 1 (the lower end of the water outlet 21 of the silicone seal 2 has an operating strip to facilitate pulling the silicone seal 2). Then, the operating part of the suction nozzle 3 is tilted downward at a certain angle relative to the horizontal surface, and the shaft part of the suction nozzle 3 contacts the anti-detachment block 14 and abuts against the side wall of the U-shaped groove 132 of the outer cover 1, tilted downward. Figure 4 Move the suction nozzle 3 downwards and to the right simultaneously, so that the suction nozzle 3 squeezes the silicone seal 2. When the silicone seal 2 is squeezed to a certain extent, the shaft of the suction nozzle 3 is inserted into the arc-shaped hole 122. At this time, rotate the suction nozzle 3 clockwise toward the air inlet 22 to push the locking assembly 4 horizontally into the locking mounting groove 13 of the outer cover 1. At this time, the sliding piece 42 of the locking assembly 4 is in the unlocked position. After the locking assembly 4 is in place, slide the sliding piece 42 downwards so that the slot 423 of the sliding piece 42 engages with the locking block 15 of the outer cover 1, which can prevent the locking assembly 4 from falling out horizontally. At the same time, the lower anti-disengagement block 411 of the locking piece 41 and the upper anti-disengagement block 14 of the outer cover 1 can prevent the locking assembly 4 from falling out vertically.

[0084] In this embodiment, the disassembly process of the suction nozzle 3 is as follows: First, slide the slider 42 upwards to disengage the slot 423 of the slider 42 from the locking block 15 of the outer cover 1. At this time, the locking assembly 4 can be slid out horizontally (the locking part 41 is U-shaped for easy operation). After the locking assembly 4 is slid out, rotate counterclockwise ( Figure 4 Rotate the nozzle 3 until its operating part is tilted downward at a certain angle, and pull the nozzle 3 outward and upward to remove the nozzle 3. At this time, the silicone seal 2 can be removed from the outer cover 1, and the outer cover 1, silicone seal 2, nozzle 3 and locking assembly 4 can be cleaned respectively.

[0085] In this embodiment, although the nozzle 3 will undergo some deformation during disassembly and assembly, during use, the rotational support of the nozzle 3 is mainly provided by the arc-shaped hole 122 of the outer cover 1, which can ensure a seal; and the nozzle 3 is prevented from falling off by the locking assembly 4 rather than the cup lid body, which can ensure that the nozzle 3 will not fall off, which is more reliable than the two structures mentioned in the background art.
