A toy flowerpot with a movable toy flower, comprises a pot with a wall, a battery compartment within the wall for accommodating a battery to power a mechanism in the toy flower. The flower includes the parts of a stem, sepal, petals and a front flower face around which the petals are mounted, at least one of which parts is a reactive part.

There are wires in the stem of the flower for directing power from the battery to the mechanism for moving one or more parts of the flower. An actuator includes a magnet and electromagnetic coil with the flower. Alternatively the battery is in the flower.

A signal receiver or sensor with the pot or flower receives a signal or senses a change caused by selectively at least one of movement of the flower or an entity in the environment of the flower or pot, temperature, sound in the environment, pressure in the vicinity of the flower or pot.

A microprocessor for processing the received signal or sensed change and generates instructions to change the operation of the electromagnetic coil in response to the signal or sensed change. The instructions cause movement of the magnet and a subsequent reaction of at least one of the reactive parts of the flower.

The signal receiver with the pot or flower receives a change in a signal caused by selectively at least one of a built in rhyme of a song, movement of the flower or an entity in the environment of the flower or pot, temperature, sound in the environment, pressure in the vicinity of the flower or pot and a mechanism in the flower for simulating a blooming artificial flower.

The mechanism includes an electromagnetic actuator, and wherein varying a voltage level and/or current direction of the actuator, the mechanism controls the petal to open and close with a different range and speed.

The toy comprises a mechanism in the flower for simulating a blooming artificial flower, the mechanism including an electromagnetic actuator. Varying a voltage level and/or current direction of the actuator, the mechanism controls the petal to open and close with a different range and speed.

A space in the pot for a battery provides power by wires up the stem of the flower to other parts of the flower. The actuator mechanism is directly or indirectly powered through the wires to effect movement of one or more parts of the flower. This includes having the movement operate to open or close of one or more parts of the flower relative to open and closed positions of the flower.

The mechanism includes one or more tubes connected for longitudinal and/or rotational movement relative to the axis of the tube. The sensor operates through the microprocessor to activate the electromagnetic coil for operation to change the position of a permanent magnet located strategically with the coil and move the tube, and the change in position moves directly or indirectly one or more parts of the flower.

The tube includes a cylindrical iron component. The magnet is affixed at a center and bottom of cylindrical iron, and the actuator provides a motive force to the petal by the reaction of a magnetic field to the current passing through the coil.

The sepal includes a trumpet shaped base. The coil of the actuator and a coil stand are fixed at a base of the sepal, and the tube and magnet of the actuator are fixed at the center of the petal.

The toy includes a plate for pushing a hinged mouth inside the front flower face, the plate being mechanically mounted with the sepal and being hinged to the mouth inside the flower face.

In an alternative form a toy flowerpot with a movable toy flower comprises a battery to power a mechanism in the toy flower. The flower includes the parts of a stem, sepal, petals and a front flower face around which the petals are mounted, at least one of which parts is a reactive part. Connections to direct power from the battery to the mechanism for moving one or more parts of the flower. An actuator includes a magnet and electromagnetic coil with the flower.

The toy can locate a power circuit and/or power supply inside the sepal.

The mounting the coil can be on a side of the petal and mounting the iron and magnet module on a base for the sepal.

The operation of the actuator without a cylindrical tube thereby reducing the magnetic field strength.

A method of operating a toy flowerpot with a movable toy flower. The steps include directing power from the battery to the mechanism for moving one or more parts of the flower. A magnet operates through power applied to an electromagnetic coil with the flower. A change caused by selectively at least one of movement of the flower or an entity in the environment of the flower or pot, temperature, sound in the environment, pressure in the vicinity of the flower or pot is sensed.

Processing the sensed change and generating instructions changes the operation of the electromagnetic coil in response to the sensed change. The instructions cause movement of the magnet and a subsequent reaction of at least one of the reactive parts of the flower.

When the coil is non-energized, the petal is in neutral, or in a semi open position, and when an electric current is applied to the coil in one direction, the coil becomes an electromagnet and attracts an iron tube and magnet module towards the coil along the longitudinal axis.

An activation module comprising the magnet and coil is fixed at or adjacent a central area of a petal whereby the petal is guided by an open end of trumpet shaped sepal and pulled inside the sepal to present the flower in a closed state, and wherein the petal includes an elastic material and the elastic nature of the petal material causes the petal to return to a neutral position when the coil is de-energized.

The method can apply an opposite current to the coil. This repels the iron and magnet module away from the coil along the longitudinal axis, and thereby the flower petal is represented in an open state.

The method includes operating a pushing plate on a petal to push the hinged mouth inside the flower face and thereby to open the mouth. The petal returns to its neutral position and the mouth closes when the coil is de-energized.

The disclosure provides a toy flowerpot with one or more movable toy flowers. The pot can have a space for battery-power to provide power by wires up the stem of the flower to other parts of the flower. In one or more parts of the flowers there is a mechanism directly or indirectly powered through the wires to effect movement of one or more parts of the flower. The movement can include opening and closing of one or more parts of the flower relative to open and closed positions of the flower. The mechanism can includes one or more tubes connected for longitudinal and/or rotational movement relative to the axis of the tube. There are one or more sensors for activating movement of the tube. The sensors can be strategically placed in the pot or a part of the flower and can operate through a PCBA to activate the tube. There is also an electromagnetic coil for operation to change the position of a permanent magnet located strategically with the coil. This change in position can move directly or indirectly one or more parts of the flower.

The artificial flower blooming mechanism includes

- 1. Electromagnetic actuator
  - It comprises 3 parts
    - a. Electric coil
    - b. Cylindrical iron
    - c. Permanent magnet fixed at the center and bottom of cylindrical iron
  - The actuator provides the motive force to the petal by the reaction of a magnetic field to the current passing through it.
- 2. Sepal
  - It is a hard plastic trumpet shaped base
  - Electric coil of the actuator and coil stand are fixed at the Sepal base
- 3. Petal
  - It can be made of soft material such as PP, PE, PVC, fabric material, paper . . . etc.
  - Iron and permanent magnet module of the actuator are fixed at the center of petal
  - A plate for pushing a hinged mouth inside flower face
- 4. Flower face
  - It is mechanically mounted on sepal
  - Hinged mouth inside the flower face
  - An elastic stamen
- 5. Stem & leaves
  - Hollow stem
  - For decoration purpose

According to the present embodiment, the flower stem is hollow, it allows 2 coil wires to pass through the stem so that the coil can be connected to an electrical power source inside a pot. Without energizing the coil, the petal is in neutral, semi open position. When an electric current is applied to the coil in one direction, the coil becomes an electromagnet and it attracts the iron and permanent magnet module towards the coil along the longitudinal axis.

As this module is fixed at the center of petal, the petal will be guided by the open end of trumpet shaped sepal and pulled inside the sepal. Then the flower will be in close state. Due to the elasticity nature of the petal material, the petal will return to its neutral position when the coil is de-energized.

Ampere's Law relates that the magnetic field of a coil is directly proportional to the applied current and hence applied voltage.

- 1. By applying different voltage levels to the coil, different magnetic field strength and therefore different petal moving range can be achieved.
- 2. By changing the coil voltage polarity, magnetic field direction can be reversed in 180° so that the petal can change from opening to closing state or vice versa.
- 3. By applying rate of voltage change or rate of Pulse Width Modulation (PWM) change, different petal moving speed can be obtained.

All above coil control functions can be easily implemented by driving the electric coil with a low cost microcontroller.

Alternative designs include

- 1. Mount an electric coil on petal side and mount the iron and permanent magnet module on sepal base. (FIG. 9)
- 2. When long travel distance of electromagnetic actuator is not required, the cylindrical iron is removed so as to reduce the magnetic field strength.
- 3. Put the power circuit and/or power supply inside the sepal rather than a pot. (FIG. 10)
- 4. The artificial flower blooming effect is activated by triggering different types of sensor such as light sensor, sound level sensor, touch sensor, motion sensor, moisture sensor . . . etc.

Apart from hinged mouth, pushing plate can also be used to activate different facial expression such as moving eyes, nose, ears . . . etc.
