Description

Technical Field

[0001] The utility model relates to the field of bubble blowing toys, in particular to a miniature bubble blowing device. Background Art

[0002] The main bubble blowing toys at present include two categories. One category is to blow bubbles with the mouth after the bubble blowing mouth is dipped in bubble liquid. This method blows out a small amount of bubbles at a time, is less interesting, unhygienic and easy to swallow the bubble liquid by mistake. The other category is bubble blowing toys such as electric bubble blowers or electric bubble blowing guns, which can often blow out many bubbles continuously and are deeply loved by children. The existing bubble blowing toys usually include a shell and a bubble blowing device composed of a suction device, a dry battery, a bubble blowing assembly, a circuit switch, a liquid storage container and a tooth box arranged on the shell. The bubble blowing assembly includes an air duct with a blower wheel installed, a bubble blowing head and a film scraping assembly. The dry battery provides power to the tooth box through the circuit switch, the suction device conveys the bubble blowing head with bubble liquid, and the blower wheel blows air to the bubble blowing head. When the bubble blowing head is already adhered with bubble liquid, bubbles can be blown out by scraping out a water film through the film scraping assembly.

[0003] The existing bubble blowing device has the problem that it uses rollers connected to the gear transmission group in the gear box to squeeze and realize mechanical water pumping, which has a complex structure, cumbersome installation and a large overall volume. Utility Model Content

[0004] In order to solve the defects in the prior art, the utility model provides a micro bubble blowing device.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a miniature bubble blowing device, including a liquid storage box, a bubble blowing sheet, a baffle, a motor and a fan blade; a mounting plate for fixing the motor is provided above the liquid storage box; the motor is electrically connected to an external control panel; the fan blade is installed on the transmission shaft of the motor; the bubble blowing sheet includes a connecting seat, a connecting rod and a bubble blowing ring; the baffle is fixedly connected to the connecting seat; the connecting seat is hinged on the liquid storage box through a connecting shaft; the fan blade and the baffle are arranged opposite to each other; the angle formed by the baffle and the bubble blowing ring is 90±5°; in a natural state, the bubble blowing ring falls into the liquid storage box under the action of gravity, and at this time the angle between the baffle and the horizontal plane is 60±5°; after the baffle is blown over by the fan blade, the angle between the bubble blowing ring and the horizontal plane is 75±5°.

[0006] After adopting this technical solution, the fan blades are driven to rotate by the motor, and the rotation of the fan blades generates a driving force on the baffle plate and pushes it backward. When the baffle plate flips backward, it drives the bubble blowing ring covered with bubble liquid to rotate out of the liquid storage box, and then the wind force generated by the fan blades blows the bubble liquid into bubbles from the bubble blowing ring and blows the bubbles away. After the fan blades stop rotating, the bubble blowing ring will return to the liquid storage box again due to its own gravity for the next bubble blowing work. The micro bubble blowing device made by this technical solution has the characteristics of simple structure and small size.

[0007] As a further improvement, the baffle is in an arc shape; the baffle includes an integrally formed connection part and a working part; a wind-gathering edge is provided on the side of the working part; a card slot is provided on the connection seat; a limiting protrusion is provided in the card slot; and the connection part is plugged and fixed in the card slot. The baffle adopts an arc-shaped design, which can gather the wind blowing vertically to the central axis, and improve the driving force on the baffle when the motor power remains unchanged. With the help of the wind-gathering edge, the purpose of assisting wind gathering is achieved, which is equivalent to a secondary strengthening of the driving force on the baffle.

[0008] As a further improvement, the connection seat, the connection rod and the bubble blowing ring are integrally formed; the bubble blowing ring is provided with evenly distributed annular protrusions; a guide plate inclined inward and downward is provided on the side opposite to the mounting plate of the liquid storage box; a mounting seat is provided on the guide plate; and the connection seat and the mounting seat are connected by a connecting shaft. The integral molding design ensures the consistency of the center of gravity of the bubble blowing piece as a whole. The design of the guide plate can return the excess bubble liquid to the liquid storage box.

[0009] Further improvements include a U-shaped splash shield; a mounting column is provided in the liquid storage box; the U-shaped splash shield is fixed to the liquid storage box through the mounting column; the width of the U-shaped splash shield is greater than the width of the baffle. The design of the U-shaped splash shield ensures the safety of the liquid level in the liquid storage box during the movement of the micro bubble blowing device. The liquid will not be thrown out of the liquid storage box due to shaking or swaying.

[0010] As a further improvement, a downwardly inclined diversion slope is provided on the U-shaped splash guard. The diversion slope is designed to divert the bubble liquid dropped from the bubble blowing ring back into the liquid storage box, thereby preventing the liquid from splashing and contaminating the micro bubble blowing device.

[0011] As a further improvement, a motor installation cavity is provided at the rear of the installation plate; ventilation holes are reserved on the installation plate. The design of the installation cavity facilitates the installation and fixing of the motor. The design of the ventilation holes improves the air supply efficiency of the fan blades.

[0012] As a further improvement, a counterweight hole is provided on the connecting rod; a counterweight screw is installed on the counterweight hole. The center of gravity of the bubble blowing piece can be slightly adjusted through the counterweight screw and the counterweight hole, ensuring that the baffle and the bubble blowing piece can be blown over normally and automatically fall back.

[0023] The fan blades are mounted on the transmission shaft of the motor; the connecting seat is hinged on the liquid storage box through the connecting shaft 10; the fan blades and the baffle are arranged opposite to each other; the angle formed by the baffle and the bubble ring is 90±5°; in the natural state, the bubble ring falls into the liquid storage box due to gravity, and at this time the angle between the baffle and the horizontal plane is 60±5°; after the baffle is blown over by the fan blades, the angle between the bubble ring and the horizontal plane is 75±5°.

[0024] In order to better illustrate the technical solution of the present application, the application scenarios of the micro bubble blowing device are now illustrated.

[0025] Application scenario 1

[0026] like Figure 7 The toy airplane includes an airplane body 25 and a remote controller 26; the airplane body is provided with a mounting groove 27 for accommodating a motor; the micro bubble blowing device described in the present application is fixed in the mounting groove; the motor is electrically connected to the control panel of the airplane body through a wire. The airplane body and the remote controller are basically the same as the drones on the market, except that the remote controller adds a bubble blowing button. When the bubble blowing button is pressed, the control panel controls the motor to rotate, and the motor rotation drives the fan blades to rotate. The wind generated by the fan blades pushes the baffle to flip backwards. During the flipping of the baffle, the bubble blowing ring will be lifted from the liquid storage box. The bubble blowing ring with bubble liquid will produce bubbles under the action of the fan blades, and the wind generated by the fan blades can also blow the bubbles away from the bubble blowing ring. After the fan blades stop rotating, the bubble blowing ring will return to the liquid storage box again due to gravity.

[0027] Application scenario 2

[0028] A toy airplane includes an airplane body, a power supply and a control panel are provided in the airplane body; the control panel is controlled by a remote controller; a mounting slot is provided at the tail of the airplane body; a micro bubble blowing device as described in the present application is fixed in the mounting slot; and a motor is electrically connected to the control panel of the airplane body through a wire. It should be noted that scenario 2 is mainly for the airplane body itself without a power supply and a control panel. The newly added power supply and control panel are mainly used to power the micro bubble blowing device and be controlled by a remote controller. The principle is the same as that of the toy airplane in scenario 1.

[0029] Application scenario three

[0030] A toy car includes a toy car body, a power supply and a control panel are arranged in the toy car body; the control panel is controlled by a remote controller; a mounting slot is arranged at the rear of the toy car body; the micro bubble blowing device as described in the present application is fixed in the mounting slot; and the motor is electrically connected to the control panel of the toy car body through a wire. The principle is the same as that of the toy airplane in scene 2.

[0031] The biggest advantage of this technical solution is that it has a simple structure, is easy to install, and has a small and light overall size.

[0032] The above-mentioned implementation mode is only the preferred mode of the present utility model, but the present utility model is not limited by the above-mentioned implementation mode. Any other changes, modifications, replacements, combinations and simplifications made without departing from the spirit and principle of the present utility model shall be equivalent replacement modes and fall within the protection scope of the present utility model.
