Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1
[0029] Please see Figure 1-10The present invention provides the following technical solution: a novel rotary timer, comprising a main housing 3, an upper housing 2 fixed to the upper end of the main housing 3, a rotary body 1 movably mounted on one side of the upper housing 2, a display screen 4 fixed to the bottom of the inner part of the rotary body 1, a main board 2 13 fixed in the middle of the inner part of the main housing 3, a first optical coupling device 12 fixed to one side of the upper end of the main board 2 13, a second optical coupling device 14 fixed to the other side of the upper end of the main board 2 13, a rotary sawtooth track 11 provided at the outer ring of the bottom end of the rotary body 1, and a rotary sawtooth track 2 15 provided at the inner ring of the bottom end of the rotary body 1.
[0030] Specifically, the knob sawtooth track 11 and the knob sawtooth track 2 15 each have two circles of sawtooths, with the same number of sawtooths and a phase difference of half a phase.
[0031] By adopting the above technical solution, the on / off signals received by the first optical coupler 12 and the second optical coupler 14 will have differences before and after, so as to determine the forward and reverse rotation state of the knob body 1.
[0032] In this embodiment, when the knob body 1 is rotated, the sawtooth tracks 11 and 15 intermittently block the optical coupling device. The optical coupling device identifies the rotation signal of the knob by the number and frequency of the sawtooth blocking, thereby realizing the input of time calculation. The knob sawtooth tracks 11 and 15 are two circles of sawtooths with the same number of teeth, differing by half a phase. Therefore, the on / off signals received by the first optical coupling device 12 and the second optical coupling device 14 will have a difference. When rotating clockwise, the first optical coupling device 12 receives the signal first, and the second optical coupling device 14 receives the signal later. Similarly, when rotating counterclockwise, the second optical coupling device 14 receives the signal first, and the first optical coupling device 12 receives the signal later, thereby determining the forward and reverse rotation state of the knob body 1. The knob body 1 can be set with a timing time, and the display screen 4 will display the corresponding time.
[0033] Example 2
[0034] The difference between this embodiment and embodiment 1 is that: specifically, a main board 8 is fixed in the middle of the interior of the main housing 3, a first Hall 6 is fixed on one side of the surface of the main board 8, a second Hall 9 is fixed on the other side of the upper end of the main board 8, a knob magnet track 5 is provided at the bottom of the knob body 1 corresponding to the first Hall 6, and a knob magnet track 10 is provided at the bottom of the knob body 1 corresponding to the second Hall 9.
[0035] By adopting the above technical solution, a main board 8 is installed inside the main housing 3. Two Hall effect devices are fixed on the main board 8, respectively aligned with the knob magnet track 5 and the knob magnet track 10. When rotating, the Hall effect devices receive intermittent signals from the knob magnet track 5 and the knob magnet track 10. By judging the frequency and quantity of the signals, the rotation angle and speed of the knob are determined, and the time is set accordingly. Because the magnets in the arrays of the knob magnet track 5 and the knob magnet track 10 are half a phase apart, the signal received by Hall effect device 6 and Hall effect device 9 will have a time difference when rotating. Therefore, when rotating clockwise, Hall effect device 6 receives the signal first, and Hall effect device 9 receives the signal later. Similarly, when rotating counterclockwise, Hall effect device 9 receives the signal first, and Hall effect device 6 receives the signal later, thereby judging the forward and reverse rotation state of the knob body 1.
[0036] Specifically, knob magnet track 5 and knob magnet track 10 are two rings of magnets in a uniform array, with the same number of magnets and a phase difference of half a phase.
[0037] By adopting the above technical solution, when the knob magnet track 1 5 and the knob magnet track 2 10 rotate, the signal received by Hall 6 No. 1 and Hall 9 No. 2 will have a time difference, so as to determine the forward and reverse rotation state of the knob body 1.
[0038] In this embodiment, during use: a main board 8 is installed inside the main housing 3. Two Hall effect sensors are fixed on the main board 8, respectively aligned with the knob magnet track 5 and the knob magnet track 10. When rotating, the Hall effect sensors receive intermittent signals from the knob magnet track 5 and the knob magnet track 10. By analyzing the frequency and quantity of the signals, the rotation angle and speed of the knob are determined, thereby setting the time. Because the magnets in the arrays of the knob magnet track 5 and the knob magnet track 10 are half a phase apart, the signal received by Hall effect sensor 6 and Hall effect sensor 9 will have a time difference during rotation. Therefore, when rotating clockwise, Hall effect sensor 6 receives the signal first, and Hall effect sensor 9 receives the signal later. Similarly, when rotating counterclockwise, Hall effect sensor 9 receives the signal first, and Hall effect sensor 6 receives the signal later, thereby determining the forward and reverse rotation state of the knob body 1.
[0039] Example 3
[0040] The difference between this embodiment and the above embodiment is that: specifically, a main board 3 20 is fixed in the middle of the interior of the main housing 3, a first transmitting rail 19 is arranged in the middle of the interior of the main board 3 20, a second transmitting rail 21 is arranged on the outer ring of the first transmitting rail 19, a second receiving rail 22 is arranged on the outside of the main board 3 20, a first receiving rail 18 is arranged on the inner ring of the second receiving rail 22, a first brush group 16 is arranged on one side of the bottom end of 1, a second brush group 23 is arranged on the other side of the bottom end of 1, and a brush body 17 is arranged inside both the first brush group 16 and the second brush group 23.
[0041] By adopting the above technical solution, a motherboard 320 is installed inside the main housing 3, and two sets of two-stage brushes are installed below the knob body 1. The first transmitting track 19 is in a continuous signal state, and the signal is conducted to the first receiving track 18 through the brushes. The first receiving track 18 is intermittent, so the signal received by the first receiving track 18 is also intermittent. The rotation angle and speed of the knob are determined by the number and frequency of the signals received by the first receiving track 18. The two rows of signal receiving tracks have the same number of endpoints and are half a phase apart. Therefore, when rotating, the signal received by the two rows of signal receiving tracks will have a time difference. So when rotating clockwise, the first receiving track 18 receives the signal first, and the second receiving track 22 receives the signal later. Similarly, when rotating counterclockwise, the second receiving track 22 receives the signal first, and the first receiving track 18 receives the signal later, thereby determining the forward and reverse rotation state of the knob body 1.
[0042] Specifically, launch orbit 19 and launch orbit 21 are set as continuous orbits, and receiving orbit 18 and receiving orbit 22 are set as intermittent orbits, with the same number of endpoints and a half-phase difference.
[0043] By adopting the above technical solution, when the knob body 1 rotates, the signal received by the two rows of signal receiving tracks will have a time difference, so as to determine the forward and reverse rotation state of the knob body 1.
[0044] Specifically, gyroscopes 7 are installed on the bottom surfaces of motherboard 1 (8), motherboard 2 (13), and motherboard 3 (20).
[0045] By adopting the above technical solution, the product is equipped with a gyroscope 7, which can identify the direction of use of the product. Therefore, the product can be placed on any of its four sides. After placement, the gyroscope 7 identifies the horizontal direction based on gravity, and the display screen 4 will switch to the correct direction according to the signal.
[0046] In this embodiment, the main board 20 is installed inside the main housing 3, and two sets of two-stage brushes are installed below the knob body 1. The first transmitting track 19 is in a continuous signal state, and the signal is conducted to the first receiving track 18 through the brushes. The first receiving track 18 is intermittent, so the signal received by the first receiving track 18 is also intermittent. The rotation angle and speed of the knob are determined by the number and frequency of the signals received by the first receiving track 18. The two rows of signal receiving tracks have the same number of endpoints and are half a phase apart. Therefore, when rotating, the signal received by the two rows of signal receiving tracks will have a time difference. So when rotating clockwise, the first receiving track 18 receives the signal first, and the second receiving track 22 receives the signal later. Similarly, when rotating counterclockwise, the second receiving track 22 receives the signal first, and the first receiving track 18 receives the signal later, thereby determining the forward and reverse rotation state of the knob body 1.
[0047] The working principle and usage process of this utility model are as follows: When the knob body 1 is rotated, the sawtooth tracks 11 and 15 intermittently block the optical coupling device. The optical coupling device identifies the rotation signal of the knob by the number and frequency of the sawtooth blocking, thereby realizing the input of time calculation. The sawtooth tracks 11 and 15 are two circles of sawtooths with the same number of sawtooths and a half-phase difference. Therefore, the on / off signals received by the first optical coupling device 12 and the second optical coupling device 14 will have a difference. When rotating clockwise, the first optical coupling device 12 receives the signal first and the second optical coupling device 14 receives the signal later. Similarly, when rotating counterclockwise, the second optical coupling device 14 receives the signal first and the first optical coupling device 12 receives the signal later, thereby determining the forward and reverse rotation state of the knob body 1. The knob body 1 can be set with a timing time, and the display screen 4 will display the corresponding time.
[0048] The product is equipped with a gyroscope 7, which can identify the direction in which the product is used. Therefore, the product can be placed on any of its four sides. After placement, the gyroscope 7 identifies the horizontal direction based on gravity, and the display screen 4 will switch to the correct direction based on the signal.
[0049] A main board 8 can also be installed inside the main housing 3. Two Hall effect devices are fixed on the main board 8 and are respectively aligned with the knob magnet track 5 and the knob magnet track 10. When rotating, the Hall effect devices will receive intermittent signals from the knob magnet track 5 and the knob magnet track 10. By the frequency and quantity of the signals, the rotation angle and speed of the knob can be determined, thereby setting the time. Because the magnets in the array in the knob magnet track 5 and the knob magnet track 10 are half a phase apart, the signal received by Hall effect 6 and Hall effect 9 will have a time difference when rotating. Therefore, when rotating clockwise, Hall effect 6 receives the signal first and Hall effect 9 receives the signal later. Similarly, when rotating counterclockwise, Hall effect 9 receives the signal first and Hall effect 6 receives the signal later, thereby determining the forward and reverse rotation state of the knob body 1.
[0050] A motherboard 320 can also be installed inside the main housing 3, and two sets of two-stage brushes can be installed below the knob body 1. The first transmitting track 19 is in a continuous signal state, and the signal is conducted to the first receiving track 18 through the brush. The first receiving track 18 is intermittent, so the signal received by the first receiving track 18 is also intermittent. The rotation angle and speed of the knob are determined by the number and frequency of the signals received by the first receiving track 18. The two rows of signal receiving tracks have the same number of endpoints and are half a phase apart. Therefore, when rotating, the signal received by the two rows of signal receiving tracks will have a time difference. So when rotating clockwise, the first receiving track 18 receives the signal first, and the second receiving track 22 receives the signal later. Similarly, when rotating counterclockwise, the second receiving track 22 receives the signal first, and the first receiving track 18 receives the signal later, thus determining the forward and reverse rotation state of the knob body 1.
[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
