[0003] The applicant has discovered at least the following technical problems in the prior art: most of these products use one of the upper lip or the lower lip to be fixed while the other is movable, resulting in a small range of mouth opening. In addition, the existing transmission mechanism for movement has a relatively complex structure, which causes the motor to require a large operating current when working, resulting in high power consumption. Utility Model Content

[0004] The purpose of this invention is to provide a moving nozzle device to solve the technical problems existing in the prior art. The preferred technical solutions among the various technical solutions provided by this invention and their numerous technical effects are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A moving mouthpiece includes a housing, an upper lip assembly, a lower lip assembly, a cam structure, a drive assembly, and a reset assembly. The front end of the upper lip assembly is movably connected to the front end of the lower lip assembly, and both are movably connected to the housing.

[0007] Preferably, the upper lip assembly includes an upper lip middle piece and an upper lip side piece, and each of the two sides of the front end of the upper lip middle piece is hinged to one of the upper lip side pieces;

[0008] The lower lip assembly includes a lower lip middle piece and a lower lip side piece, and each of the two sides of the front end of the lower lip middle piece is hinged to one of the lower lip side pieces.

[0009] Each of the upper lip side pieces is hinged at one end away from the upper lip center piece to one of the lower lip side pieces at one end away from the lower lip center piece;

[0010] The middle part of the upper lip intermediate piece is movably connected to the middle part of the lower lip intermediate piece, and both are movably connected to the housing. The rear end of the upper lip intermediate piece is located below the rear end of the lower lip intermediate piece, and both are in contact with the cam structure.

[0011] The reset component is connected to the front middle part of the upper lip and the front middle part of the lower lip, respectively.

[0012] Preferably, the reset component is a tension spring, and the two ends of the tension spring are respectively connected to the front middle part of the upper lip and the front middle part of the lower lip.

[0013] Preferably, each of the upper lip side pieces, at the end away from the upper lip middle piece, and the corresponding lower lip side piece, at the end away from the lower lip middle piece, are connected to a sliding block. The housing is provided with a sliding groove at the corresponding position of each sliding block, and the sliding block is slidably connected to the corresponding sliding groove.

[0014] Preferably, the drive assembly includes a drive motor, a transmission gear structure, and a transmission shaft. The drive motor is connected to the transmission gear structure, the transmission gear structure is connected to the transmission shaft, and the cam structure is connected to the transmission shaft.

[0015] Preferably, the transmission gear structure includes a gear set, a movable gear, a ratchet, and a pawl. The gear set is connected to the drive motor and meshes with the movable gear.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Reference Figures 1 to 4 This utility model provides a moving mouth device, including a housing 1, an upper lip assembly 2, a lower lip assembly 3, a cam structure 4, a drive assembly 5, and a reset assembly 6;

[0036] The front end of the upper lip assembly 2 is movably connected to the front end of the lower lip assembly 3, and both the front ends of the upper lip assembly 2 and the lower lip assembly 3 are movably connected to the housing 1. The front end of the upper lip assembly 2 is located above the front end of the lower lip assembly 3.

[0037] The middle part of the upper lip assembly 2 is movably connected to the middle part of the lower lip assembly 3, and both the middle parts of the upper lip assembly 2 and the middle parts of the lower lip assembly 3 are movably connected to the housing 1. Preferably, the connection is made through a movable shaft, which forms a fulcrum based on the housing 1.

[0038] The rear end of the upper lip assembly 2 is located below the rear end of the lower lip assembly 3, and both are in contact with the cam structure 4.

[0039] The drive assembly 5 is connected to the housing 1, the cam structure 4 is connected to the drive assembly 5 in a transmission manner, and the reset assembly 6 is connected to the upper lip assembly 2 and the lower lip assembly 3 respectively.

[0040] The cam structure 4 includes two long shaft ends and two short shaft ends. When the upper lip assembly 2 and the lower lip assembly 3 move to the farthest distance, the two long shaft ends contact the rear end of the upper lip assembly 2 and the rear end of the lower lip assembly 3, respectively. When the upper lip assembly 2 and the lower lip assembly 3 move to the closest distance, the two short shaft ends contact the rear end of the upper lip assembly 2 and the rear end of the lower lip assembly 3, respectively.

[0041] When the mouth-opening device needs to open the mouth, the drive component 5 is activated, which drives the cam structure 4 to rotate. The single rotation amplitude is preferably 90°, so that the two long shaft ends of the cam structure 4 contact the rear end of the upper lip component 2 and the rear end of the lower lip component 3 respectively. At this time, the upper lip component 2 and the lower lip component 3 move to the farthest distance to achieve the mouth-opening effect.

[0042] When the moving mouth device needs to close the mouth, the drive component 5 does not work, and the reset component 6 can drive the cam structure 4 to rotate 90°, so that the two short shaft ends are in contact with the rear end of the upper lip component 2 and the rear end of the lower lip component 3 respectively. At this time, the upper lip component 2 and the lower lip component 3 move to the closest distance to achieve the mouth-closing effect.

[0043] The upper lip assembly 2 and the lower lip assembly 3 can be combined to form a scissor-shaped structure. With the help of the lever principle, they can move simultaneously during the mouth opening process, which greatly increases the range of mouth opening and reduces the operating current of the drive assembly 5, thus saving more power.

[0044] Meanwhile, since the front end of the upper lip component 2 is movably connected to the front end of the lower lip component 3, and both the front ends of the upper lip component 2 and the lower lip component 3 are movably connected to the housing 1, the front ends of the upper lip component 2 and the lower lip component 3 can have more ways of movement, forming multiple angle changes, making the mouth movement effect more obvious and more interesting.

[0045] As an optional implementation, the upper lip assembly 2 includes an upper lip middle piece 21 and upper lip side pieces 22. The two sides of the front end of the upper lip middle piece 21 are hinged to one upper lip side piece 22, so that the upper lip middle piece 21 can be rotatably connected to the two upper lip side pieces 22 on both sides.

[0046] The lower lip assembly 3 includes a lower lip middle piece 31 and a lower lip side piece 32. The two sides of the front end of the lower lip middle piece 31 are hinged to a lower lip side piece 32, so that the lower lip middle piece 31 can be rotatably connected to the two lower lip side pieces 32 on both sides.

[0047] Each upper lip side piece 22 is hinged at one end away from the upper lip middle piece 21 to the end of a lower lip side piece 32 away from the lower lip middle piece 31, thus forming a rotatable connection between the two.

[0048] The aforementioned multiple rotating connections can work together to create multiple angle changes, making the mouth-moving effect more obvious and more interesting;

[0049] The middle part of the upper lip intermediate part 21 is movably connected to the middle part of the lower lip intermediate part 31 and both are movably connected to the housing 1. The rear end of the upper lip intermediate part 21 is located below the rear end of the lower lip intermediate part 31 and both are in contact with the cam structure 4.

[0050] The reset component 6 is connected to the front middle part of the upper lip intermediate part 21 and the front middle part of the lower lip intermediate part 31, respectively.

[0051] As an optional implementation, the reset component 6 is a tension spring. The two ends of the tension spring are connected to the front middle part of the upper lip intermediate component 21 and the front middle part of the lower lip intermediate component 31, respectively. The tension spring has good elasticity. When the upper lip component 2 and the lower lip component 3 move to the farthest distance, the tension spring stores force to the maximum value. When the drive component 5 does not work, the cam structure 4 loses power. The tension spring can recover its deformation by its own tension, drive the cam structure 4 to rotate and make the upper lip component 2 and the lower lip component 3 move closer to each other, pull back to their original positions, and form a closed mouth.

[0052] As an optional implementation, each upper lip side piece 22 and the corresponding lower lip side piece 32, which are located away from the upper lip middle piece 21, are connected to a sliding block 7. The housing 1 is provided with a sliding groove 11 at the corresponding position of each sliding block 7, and the sliding block 7 is slidably connected to the corresponding sliding groove 11.

[0053] By using a combination structure with sliding blocks 7 and sliding grooves 11, when the mouth is open, the two sliding blocks 7 can slide towards the center inside the sliding grooves 11, allowing the upper lip assembly 2 and the lower lip assembly 3 to open their mouths wider.

[0054] As an optional implementation, the drive assembly 5 includes a drive motor 51, a transmission gear structure 52 and a transmission shaft 53. The drive motor 51 is preferably a servo motor. The drive motor 51 is connected to the transmission gear structure 52, the transmission gear structure 52 is connected to the transmission shaft 53, and the cam structure 4 is connected to the transmission shaft 53.

[0055] Furthermore, the transmission gear structure 52 includes a gear set 521, a movable gear 522, a ratchet 523, and a pawl 524. The gear set 521 is connected to the drive motor 51 and meshes with the movable gear 522. The movable gear 522 is connected to the ratchet 523. The pawl 524 is connected to the transmission shaft 53 and forms a ratchet mechanism with the ratchet 523.

[0056] When the drive motor 51 starts, it can drive the gear set 521 to drive the movable gear 522 to rotate. The movable gear 522 drives the ratchet 523 to rotate synchronously. At this time, the ratchet 523 and the pawl 524 form a ratchet mechanism, which drives the pawl 524 to rotate synchronously, thereby driving the transmission shaft 53 to rotate synchronously, and then driving the cam structure 4 to rotate synchronously, so that the two long shaft ends of the cam structure 4 contact the upper lip assembly 2 and the lower lip assembly 3.

[0057] When the drive motor 51 stops, the gear set 521, the movable gear 522 and the ratchet 523 stop rotating. At this time, the tension spring returns to its elastic deformation, which drives the cam structure 4 and the pawl 524 to rotate synchronously, so that the two short shaft ends of the cam structure 4 contact the upper lip assembly 2 and the lower lip assembly 3.

[0058] Throughout the process, the tension of the spring does not need to be large, which reduces the force required for the drive motor 51 to open the mouth. Therefore, the operating current of the drive motor 51 is much smaller than that of the existing structure. At the same time, due to the adoption of a scissor-shaped structure and the lever principle, the operating current of the drive motor 51 is further reduced, making it more energy-efficient.

[0059] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
