Electric grooming device
An electric grooming appliance includes a housing, a grooming device, an electric motor, and a controller. In some embodiments, the electric grooming appliance is capable of operating in different modes and includes a user interface which allows a user to communicate with the controller and select at least one of the modes. The electric grooming appliance may provide information to the user relating to information determined and/or detected during a grooming session. In addition, the electric grooming appliance may record or store grooming session information on a memory and estimate future operating parameters based on the grooming session information. The electric grooming appliance may include a trimmer assembly that is positionable between a stowed position and an operative position.
1. An electric grooming appliance comprising:
a housing;
a hair cutting device supported by the housing and including at least one moveable blade configured to cut hair;
an electric motor contained in the housing, wherein the electric motor is configured to drive the at least one moveable blade when the electric motor receives an amperage draw from a power supply;
a sensor configured to detect the amperage draw of the electric motor from the power supply; and
a controller contained in the housing and configured to receive information from the sensor, wherein the controller is configured to compare the amperage draw to a threshold amperage, wherein if the amperage draw is greater than the threshold amperage the controller is configured to adjust a power output of the power supply, and wherein the controller is configured to receive a plurality of samples of the amperage draw detected at a first sampling frequency by the sensor and determine at least one of an average amperage draw and a maximum amperage draw.
2. The electric grooming appliance in accordance with claim 1 , wherein the power supply comprises a battery contained in the housing, the controller configured to determine a relationship between the amperage and a runtime of the battery.
3. The electric grooming appliance in accordance with claim 1 , wherein the controller is configured to compare the amperage draw to a plurality of threshold amperages and adjust the power output of the power supply when the amperage draw exceeds each threshold amperage.
4. The electric grooming appliance in accordance with claim 1 , wherein the controller is further configured to determine the threshold amperage based on an unloaded amperage draw of the electric motor.
5. The electric grooming appliance in accordance with claim 1 further comprising a user interface configured to receive at least one user input relating to a speed control mode of the electric grooming appliance, wherein the controller is configured to adjust the power output of the power supply based at least partly on the user input.
6. The electric grooming device of claim 1 , further comprising:
a housing;
a hair cutting device supported by the housing, the hair cutting device including at least one moveable blade configured to facilitate cutting of hair;
an electric motor contained in the housing, and wherein the electric motor is configured to drive the at least one moveable blade;
a battery forming the power supply, wherein the battery is configured to deliver a power output to the electric motor;
a user interface comprising a display, and wherein the user interface is configured to receive at least one input from a user to switch the hair grooming appliance between an ON mode and an OFF mode, wherein the electric motor drives the at least one moveable blade in the ON mode; and
wherein the controller includes a memory, wherein the controller is configured to identify a plurality of grooming sessions and store a start time and an end time in the memory for each of a respective grooming session,
wherein the start time is a time when the user selects the ON mode and the end time is a time when the user selects the OFF mode, the controller is further configured to:
determine an elapsed time for each grooming session, wherein the elapsed time is an amount of time from the start time to the end of the respective grooming session;
store in the memory the elapsed times that are greater than a threshold time, the elapsed times that are less than the threshold time are not stored in the memory;
determine an average elapsed time, wherein the average elapsed time is the average of the elapsed times stored in the memory; and
determine a number of the elapsed times prior to a parameter of the battery falling below a threshold level, wherein the number of elapsed times remaining includes the battery life divided by the average elapsed time.
7. The electric grooming appliance in accordance with claim 6 , wherein the controller is configured to send a signal to the user interface to display an indication relating to a number of elapsed times remaining.
8. The electric grooming appliance in accordance with claim 6 wherein the sensor is configured to detect at least one parameter of the battery during each groom session and send a signal to the controller.
9. The electric grooming appliance in accordance with claim 6 , wherein the controller is configured to determine if the number of elapsed times remaining is less than one when the user selects the ON mode and provide an indication to the user if the number of elapsed times remaining is less than one.
10. The electric grooming appliance in accordance with claim 9 , wherein the controller is configured to switch the electric grooming appliance to the OFF mode if the number of elapsed times remaining is less than one.
11. The electric grooming appliance of claim 1 , further comprising:
a user interface;
wherein the controller is communicatively coupled to the electric motor, the user interface, and the sensor; and
wherein the controller comprises a memory, and wherein the controller is configured to interpret a signal from the sensor to determine a parameter related to a force exerted on the moveable blades from a surface of a skin of a user, and wherein the controller is configured to send a signal to the user interface when the parameter reaches a threshold.
12. The electric grooming appliance in accordance with claim 11 , wherein the controller is configured to adjust at least one operating parameter of the electric grooming appliance based on the determined parameter.
13. The electric grooming appliance in accordance with claim 11 , wherein the user interface provides an indication to the user when the parameter reaches the threshold, wherein the indication includes at least one of an auditory signal, a visual signal, and a tactile signal.
14. The electric grooming appliance in accordance with claim 11 , wherein the controller is configured to transmit a signal to a vibratory unit to cause the vibratory unit to vibrate when the parameter reaches the threshold.
