Description

Technical Field

[0001] The utility model relates to a bubble machine which can blow out bubbles continuously. Background Art

[0002] A bubble machine can continuously generate and blow bubbles, making it suitable for use as a toy, stage effects, or to enhance the atmosphere of a party. The bubble machine consists of a base and a body. The body is mounted on the base, housing a bubble blowing mechanism and a nozzle for blowing bubbles. Traditional bubble machines have a fixed body, so they can only blow bubbles in one direction, which is unsuitable for many applications.

[0003] Utility model patent application number CN2907813Y discloses an electric bubble machine that uses a transmission mechanism within its base to drive the machine body to rotate vertically, allowing it to automatically blow bubbles in all directions. However, the machine rotates at a constant speed, lacking a sense of rhythm and a distinct blowing direction, making it appear rigid. Utility Model Content

[0004] The purpose of the present utility model is to overcome the above-mentioned shortcomings and provide a bubble machine, the blowing direction of which can sometimes remain unchanged and sometimes rotate and change during the entire blowing process.

[0005] The purpose can be achieved according to the following scheme: the bubble machine includes a base and a body, the body is rotatably mounted on the base, a bubble blowing mechanism is installed inside the body, and a bubble blowing port for blowing bubbles is provided on the surface of the body; the characteristics are: the weight of the body is directly pressed on the upper surface of the base; a polygonal guide hole with a polygonal horizontal cross section is also provided on the upper part of the base, a polygonal guide block can be vertically slidably installed in the polygonal guide hole, and the horizontal cross section of the polygonal guide block corresponds to the horizontal cross section of the polygonal guide hole; the polygonal guide block is fixedly connected to a vertical shaft, the upper end of the vertical shaft is fixedly connected to a first horizontal gear, and the first water The flat gear, the vertical shaft, and the polygonal guide block are fixedly connected as a whole and slide vertically synchronously. The three are fixedly connected in the circumferential direction and cannot rotate relative to each other. The first horizontal gear is located inside the machine body. A return spring is also provided to apply an upward elastic force to the first horizontal gear. A motor and a second horizontal gear are installed in the machine body. The motor drives the second horizontal gear through a first transmission mechanism. When the vertical position of the first horizontal gear is aligned with the second horizontal gear, the first horizontal gear meshes with the second horizontal gear. When the vertical position of the first horizontal gear is offset from the second horizontal gear, the first horizontal gear disengages from the second horizontal gear.

[0006] An eccentric rotating block is also installed in the fuselage, and the eccentric rotating block is located above the first horizontal gear. The rotating axis of the eccentric rotating block is horizontal, and the eccentric rotating block is coaxially fixedly connected to the third gear; a second transmission mechanism that drives the third gear to rotate is also provided in the fuselage; when the distal end of the eccentric rotating block rotates to the lower part of its rotation trajectory, the distal end of the eccentric rotating block touches the upper surface of the first horizontal gear.

[0007] The second transmission mechanism can be driven by the first transmission mechanism.

[0008] The second transmission mechanism includes a worm and a fourth horizontal gear. The worm and the fourth horizontal gear are coaxially fixedly connected. The worm drives the third gear, and the fourth horizontal gear is driven by a motor.

[0009] The fourth horizontal gear is driven by the motor through the first transmission mechanism.

[0010] A cylindrical block is fixedly connected to the top of the polygonal guide block. A circular hole is opened on the bottom surface of the fuselage. The hole edge of the circular hole is sleeved outside the cylindrical block. The central axes of the cylindrical block, the circular hole and the first horizontal gear overlap.

[0011] When the first horizontal gear slides vertically to the upper end of its sliding stroke, the first horizontal gear disengages from the second horizontal gear; when the first horizontal gear slides vertically to the lower end of its sliding stroke, the vertical position of the first horizontal gear is aligned with the second horizontal gear.

[0012] The so-called distal end of the eccentric rotating block refers to the end of the eccentric rotating block away from its rotating axis.

[0013] The utility model has the following advantages and effects:

[0014] During use of the utility model, the motor drives the second horizontal gear and the third gear to rotate continuously, and the third gear drives the eccentric rotating block to rotate around its rotating shaft. When the distal end of the eccentric rotating block touches the first horizontal gear, the distal end of the eccentric rotating block applies downward pressure to the first horizontal gear. The first horizontal gear moves up and down under the joint action of the distal end of the eccentric rotating block and the return spring, sometimes aligning with and engaging the second horizontal gear, and sometimes disengaging from the second horizontal gear; when the first horizontal gear is engaged with the second horizontal gear, since the first horizontal gear cannot rotate relative to the base, the second horizontal gear constitutes a planetary gear of the first horizontal gear, and drives the fuselage to rotate around the central axis of the vertical axis (that is, the central axis of the first horizontal gear), so that the direction of the bubble blowing port rotates and changes, and the direction of the bubbles blown out continuously changes during this stage; when the first horizontal gear disengages from the second horizontal gear, the direction of the bubble blowing port temporarily remains unchanged, that is, bubbles are continuously blown out in the focus direction during this stage; therefore, the direction of the entire bubble blowing process sometimes pauses and sometimes rotates and changes, which has a sense of rhythm and appears vivid and interesting.

A circular hole 20 is formed on the bottom surface of the body 2 , and the edge of the circular hole 20 is sleeved on the outside of the cylindrical block 31 . The central axes of the cylindrical block 31 , the circular hole 20 and the first horizontal gear 41 overlap.

[0024] Figure 5 、 Figure 6 、 Figure 7 As shown, the first horizontal gear 41 is located inside the body 2; a return spring 32 is also provided inside the body 2 to apply an upward elastic force to the first horizontal gear 41; a motor 5 and a second horizontal gear 42 are installed in the body 2, and the motor 5 drives the second horizontal gear 42 through a first transmission mechanism; the first transmission mechanism is a transmission gear set 7; when the first horizontal gear 41 slides vertically to the lower end of its sliding stroke, the vertical position of the first horizontal gear 41 is aligned with the second horizontal gear 42, and the first horizontal gear 41 and the second horizontal gear 42 are meshed, as shown in FIG. Figure 8 When the first horizontal gear 41 slides vertically to the upper end of its sliding stroke, the vertical position of the first horizontal gear 41 is staggered with the second horizontal gear 42, the first horizontal gear 41 is disengaged from the second horizontal gear 42, as shown Figure 6 shown.

[0025] Figure 5 、 Figure 6 、 Figure 7As shown, an eccentric rotating block 6 is also installed in the fuselage, and the eccentric rotating block 6 is located above the first horizontal gear 41. The rotating shaft 60 of the eccentric rotating block 6 is horizontal, and the eccentric rotating block 6 is coaxially fixedly connected to the third gear 43; a second transmission mechanism that drives the third gear 43 to rotate is also provided in the fuselage 2; the second transmission mechanism includes a worm 45 and a fourth horizontal gear 44, and the worm 45 is coaxially fixedly connected to the fourth horizontal gear 44.

[0026] The operating principle of the above embodiment is as follows:

[0027] During use, the motor 5 drives the second horizontal gear 42 to rotate continuously through the transmission gear set 7. At the same time, the transmission gear set 7 drives the third gear 43 to rotate continuously through the fourth horizontal gear 44 and the worm 45 of the second transmission mechanism. The third gear 43 drives the eccentric rotating block 6 to rotate continuously around its rotating shaft 60. When the distal end of the eccentric rotating block 6 rotates to the lower part of its rotation trajectory, the distal end of the eccentric rotating block 6 contacts and presses the upper surface of the first horizontal gear 41, as shown in FIG. Figure 8 As shown. When the distal end of the eccentric rotating block 6 contacts the upper surface of the first horizontal gear 41, the distal end of the eccentric rotating block 6 applies downward pressure to the first horizontal gear 41. The first horizontal gear 41 moves up and down under the combined action of the distal end of the eccentric rotating block 6 and the return spring 32, and sometimes aligns with and engages with the second horizontal gear 42 (as shown in FIG. Figure 8 As shown), sometimes disengaging from the second horizontal gear (as Figure 5 、 Figure 6 As shown), when the first horizontal gear 41 is engaged with the second horizontal gear 42, since the polygonal guide block 3 cannot rotate in the polygonal guide hole 10 of the base 1, that is, the first horizontal gear 41 cannot rotate relative to the base 1, the second horizontal gear 42 constitutes a planetary gear of the first horizontal gear 41, and drives the body 2 to rotate around the central axis of the first horizontal gear 41, so that the direction of the bubble blowing port 21 is rotated and changed, and the direction of the bubbles blown continuously changes during this stage; when the first horizontal gear 41 is disengaged from the second horizontal gear 42, the direction of the bubble blowing port 21 is temporarily fixed, which means that bubbles are continuously blown in the key direction during this stage; therefore, the direction of the entire bubble blowing process sometimes pauses and sometimes rotates and changes, which has a sense of rhythm and appears vivid and interesting.
