Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Referring to fig. 1, fig. 1 is a schematic cross-sectional view of a dispenser according to a first embodiment of the present invention in use. In the present embodiment, the dispenser 10 includes a dispensing unit 110, and an electric storage unit 190.
The dispensing unit 110 includes a housing 111 and a spindle 115.

In the present embodiment, the housing 111 includes a back plate (not shown), two side plates (not shown) connected to and disposed opposite to the back plate, and a front cover (not shown) connected to the two side plates. Typically, the back plate is mounted to a wall or similar vertical surface. The front cover is connected to the side plate in a rotatable manner, and the connection position is at an end of the connection position of the side plate and the back plate, which is far away from the ground, so that the front cover can be opened, and the consumable 160 can be repeatedly placed in the accommodating space 119. In other embodiments, the front cover may be coupled to the back plate, and preferably is pivotally or removably coupled. Alternatively, the at least one side panel may be detachably or rotatably coupled to the back panel or the front cover so that the at least one side panel can be opened to repeatedly place the consumable 160 in the accommodating space 119. The means of detachable or rotatable connection include, but are not limited to, hinges, bolts, screw connections. The housing 111 is formed with an extraction opening through which a portion of the consumable 160 extends out of the housing 111 for use by a user. The position of the extraction port may be a lower, middle or upper portion of the housing 119. Serrated edges may also be provided on the extraction port, or additional serrations may be provided, to facilitate the user in cutting off the consumable 160. The material of the housing 111 is not limited, and is paper, plastic, metal, polymer, or the like, preferably plastic.
The consumable 160 is a sheet 164, and the sheet 164 is rolled up by a cylindrical core 162, the cylindrical core 162 being tubular and having a hollow channel inside. Typically, the consumable 160 is roll toilet paper.
The shaft core 115 is rotatably disposed in the housing 119 and coupled to at least one of the two side plates disposed opposite to each other. In the present embodiment, the shaft core 115 includes a fixed shaft 116 and a cylinder 117 disposed coaxially with the fixed shaft 116. The fixed shaft 116 is a cylinder, and the cylinder 117 is a torus. The number of the fixed shafts 116 and the cylinder 117 is two, the two fixed shafts 116 are respectively connected with two side plates of the shell 119, and the cylinder 117 is rotatably connected to one end of the fixed shaft 116, which is far away from the side plate for fixing the cylinder. The radial direction of the cylinder 117 is perpendicular to the axial direction of the shaft core 115. With further reference to fig. 2, fig. 2 is an enlarged cross-sectional schematic view of the mandrel portion of fig. 1. The inner surfaces 713 of the two cylindrical bodies 117 facing each other are formed with protruding portions 711, and the two protruding portions 711 are disposed opposite to each other. The radial cross-sectional area of the end of the protrusion 711 remote from the inner surface 713 is tapered to form a slope 712 such that the axial cross-section of the protrusion 711 is trapezoidal. The diameter of the surface of the protrusion 711 remote from the inner surface 713 is smaller than the inner diameter of the hollow passage inside the cylindrical tube 162, and the inner diameter of the surface where the protrusion 711 and the inner surface 713 are connected is greater than or equal to the inner diameter of the hollow passage inside the cylindrical tube 162. The spacing between the two protrusions 711 is less than the length of the consumable 160 and the spacing between the two inner surfaces 713 is greater than or equal to the length of the consumable 160, preferably equal to. In this manner, the consumable 160 can be detachably attached to the spindle 115. In addition, in order to increase the friction force between the circular core tube 162 and the cylinder 117 so that the circular core tube 162 and the cylinder 117 rotate synchronously, a groove or a rib may be provided on the surface of the connection portion of the cylinder 117 and the circular core tube 162. That is, grooves or ribs may be provided on the slope 712. The cylinder 117 may have a cylindrical structure, an elastic device, a fin structure, or the like.
The electric storage unit 190 includes a battery (not shown), a magnet 192, and a coil 194. The coil 194 is disposed on the fixed shaft 116, the magnet 192 is disposed on the cylinder 117, the charging end of the battery is connected to the coil 194, and the discharging end is connected to the member to be powered. The coil 194 is disposed to extend from an end of the fixed shaft 116 away from the side wall to which it is connected in a direction away from the side wall, and the coil 194 is disposed in parallel with the magnet 192. In other embodiments, the power storage unit 190 may not include a battery, and the coil 194 is directly connected to the component to be powered.
When the user uses the sheet 164, the sheet 164 rotates the cylinder 117, and the magnet 192 provided on the cylinder rotates coaxially with the cylinder 117. When the magnet 192 rotates, the magnetic field generated by the magnet cuts the coil 194, thereby generating a current at the coil 194, which charges the battery. Therefore, the mechanical energy in the distributor 10 is converted into electric energy, the electric energy is stored by the storage battery and used when needed, energy can be saved, and the mechanical energy in the distributor 10 is perfectly utilized.
In addition, the design enables the length of the magnet 192 and the coil 194 to be long, and the magnet can be well extended in a limited space, so that the current generated by the coil 194 is large, and the storage battery can be well charged. The length and diameter of the coil 194 and the range of the magnetic flux of the magnet 192 can be calculated from the faraday's law of electromagnetic induction δ BLvsin θ according to actual conditions. The magnitude of the induced current is in direct proportion to the magnetic induction intensity B, the length L of the lead, the movement speed v and the sine of an included angle theta between the movement direction and the direction of the magnetic force lines. The induction current can be increased by increasing the magnetic induction B, increasing the length L of the wire cutting the magnetic line of force, increasing the cutting speed v, and cutting the magnetic line of force perpendicularly as much as possible (θ ═ 90 °). Or configured according to actual conditions. According to ohm's law, the voltage is current resistance, so that the rotation speed of cutting the magnetic induction lines is inconsistent due to different forces of pulling the objects to be distributed by each person, the input voltage is inconsistent, and a voltage compensation/voltage stabilization circuit can be arranged.
Referring to fig. 3 and 4, fig. 3 is a schematic structural diagram of a distributor according to a second embodiment of the present invention. Figure 4 is a schematic cross-sectional view of the dispenser of figure 3 in use. In the present embodiment, the dispenser 20 includes a dispensing unit 210, a sensor unit 220, a control unit 230, and an electric storage unit 290.
The distribution unit 210 and the storage unit 290 have the same structure as the distribution unit 110 and the storage unit 190 in the previous embodiment, and are not described again. However, in the present embodiment, the power storage unit 290 includes the first magnet 292 and the first coil 294.
The sensor unit 220 includes a second magnet 222 and a second coil 224. In the present embodiment, the second coil 224 is disposed on the housing 211, and the second magnet 222 is disposed on the shaft core 215. When the shaft core 215 rotates, the second magnet 222 and the second coil 224 move relatively, so that an induced current is generated in the second coil 224. In other embodiments, the positions of the second coil 224 and the second magnet 222 may be reversed. Specifically, the second magnet 222 is disposed on a surface of the side wall of the cylinder 217 facing the corresponding side plate, and the second coil 224 is disposed on a surface of the side wall of the cylinder 217 facing the cylinder 217 and disposed correspondingly. When the shaft core 215 rotates, the second magnet 222 disposed on the shaft core 215 is rotated and passes near the second coil 224. More specifically, the second magnet 222 will move from a position away from the second coil 224 to a position proximate to the second coil 224 and away from the second coil 224 a second time, and each rotation of the core 215 causes the second magnet 222 to pass near the second coil 224 a second time, which corresponds to the second coil 224 moving relative to the second magnet 222 and cutting the magnetic induction lines as the second magnet 222 sweeps from near the second coil 224, causing an induced current to be generated in the second coil 224. The same applies when the second magnet 222 fixes the second coil 224 to rotate, as long as the second magnet 222 and the second coil 224 move relatively.
The control unit 230 includes a function unit 232 and a counting unit 231. The functional unit 232 includes a signal prompting module (not shown) for prompting by sound, light, display or signal transmission. Preferably, the function unit 232 includes at least one of a display component, an audio component, or a communication module. The display component is a display screen, a display, a lamp group, a color lamp, a color code or an indicator lamp and the like. For example, information such as the number of sheets 264 is directly displayed on the display screen, information such as the shortage of the remaining amount of the sheets 264 is displayed by the arrangement of the lamp groups, information such as the shortage of the remaining amount of the sheets 264 is displayed by the change of the color lamps/color patches, and information such as the shortage of the remaining amount of the sheets 264 is displayed by the turning on or flashing of the indicator lamps. Preferably, the display part is installed on the panel on the side facing the user, so that the user and the maintenance personnel can conveniently see the information, and the use and the maintenance are convenient. Further, control section 230 is connected to a battery (not shown) in power storage section 290, and the battery supplies power to control section 230.
It is to be understood that the display unit is not limited to displaying information such as the shortage of the remaining amount of the sheet 264, and other necessary information may be displayed by the display unit, and the maintenance person may know whether or not the sheet 264 needs to be replaced by reading the information.
The audio component is a device for prompting the user or the maintenance person with sound the information of the usage amount of the sheet 264 or the information of the near-end. It will be appreciated that the audio assembly is not limited to prompting sheet 264 usage information or imminent exhaustion information, but may be used to prompt other desired information.
The communication module is at least one of a wireless communication module or a wired communication module. The wireless communication refers to twisted pair telephone network, internet, optical fiber transmission network and the like, and the wireless communication comprises WLAN, GSM, CDMA, LTE, Bluetooth, infrared and the like. In this embodiment, the functional unit 232 is a lamp, the circuit is connected, and the lamp emits light to remind users and maintenance personnel of the information of the paper use condition or the paper use-up information.
The counting unit 231 is connected to the second coil 224 in the sensor unit 220, counts once when the sensor unit 220 generates an induced current, transmits a control signal, and activates the function unit 232 to prompt the function unit 232. In other embodiments, a threshold number is stored in the control unit 230, which is the number of turns the consumable 260 has required to turn from full to no more. That is, when the count of the counting unit 231 reaches the threshold number, the consumable 260 is just consumed, and the counting unit 231 is caused to send the control signal and activate the functional unit 232. In addition, since the consumable 260 has a thickness, which causes a difference in diameter of each circle, the usage amount of the consumable can be obtained according to the thickness of the consumable and the outer diameter of the cylindrical core tube, and the amount of the remaining consumable can be obtained by using the following formula:
if: the outer diameter of the round core tube is R, the thickness of the consumable 260 is h, and the total number of layers of the consumable is n
Length of nth layer: pi (R +2nh)
Length of remaining consumable: l ═ n (pi R + pi (R +2nh)) × n/2 ═ pi × (2R + nh) × n/2
With further reference to fig. 5, fig. 5 is a schematic diagram of the operation of the sensor unit of fig. 3. As shown, when the second magnet 222 and the second coil 224 move relative to each other, a process of moving away from, approaching away from, occurs, and in this process, the magnetic induction line and the second coil 224 generate a cutting phenomenon, so that an induced current is generated in the second coil 224. Similarly, the working principle of the power storage unit 290 is the same, but the induced current generated by the first coil 294 is transmitted to the battery to charge the battery.
When the consumable 260 is used, the shaft core 215 is driven to rotate, the second magnet 222 disposed on the shaft core 215 rotates, the second coil 224 generates an induced current every time the consumable 260 approaches or leaves the second coil 224, the induced current is transmitted to the counting unit 231 of the control unit 230, and the counting unit 231 performs counting. When the counted number reaches the threshold number, a control signal is sent and the functional unit 232 is activated, the functional unit 232 prompts by means of sound, light, display or a signal. At this point, the worker is dispatched to place the consumable 20 and then enters the next cycle. When consumable 260 is used, cylinder 217 rotates, and magnet 292 provided in the cylinder rotates coaxially with cylinder 217. When the magnet 292 rotates, the magnetic field generated by the magnet cuts the coil 294, so that a current is generated at the coil 294, which charges the battery, which supplies power to the control unit 230.
In the above manner, since the second magnet and the second coil are not in contact, paper dust of paper towels in the dispenser does not affect the sensor unit, and the dispenser and a system using the dispenser are not prone to malfunction. In addition, the generated induced current can also charge a power supply system of the distributor system, so that the service life of the battery is prolonged.

In this embodiment, the first coil 394 is disposed inside the sidewall of the housing 311, and the first magnet 392 is disposed on the cylindrical body 317 of the shaft core 315. When the shaft core 315 rotates, the first magnet 392 and the first coil 394 move relatively, so that an induced current is generated in the first coil 394. Specifically, the first magnet 392 is disposed on a surface of the sidewall of the cylinder 317 facing the corresponding side plate, and the other is disposed on a surface of the side plate facing the cylinder 317 and disposed correspondingly.

Since the induced current generated by the coil in the sensor unit 520 is sometimes small and cannot activate the counting unit 531 to count, a signal amplifying circuit unit 533 capable of amplifying the induced current needs to be added between the coil and the counting unit 531. The signal amplifying circuit unit 533 may employ a signal amplifying circuit of a triode or a field effect transistor. For example, the signal amplifying circuit unit 533 is an NPN type transistor, the coil is electrically connected to the collector and the emitter of the transistor, and the counting unit 531 is electrically connected to the collector and the emitter of the transistor. The coil cuts the magnetic induction line to generate weak current, so that an output end circuit connected to the collector and emitter ends of the triode is switched on, and the counting unit 531 counts.
The storage unit 534 stores one or more of preset text, image or sound information, such as "paper is used up, paper is required to be changed" and the like, and is connected to the function unit 532, and the stored information is displayed or transmitted through the function unit.
