DETAILED DESCRIPTION
[0056] It should be understood that the specific embodiments described herein are merely illustrative of the application and do not limit the application.
[0057] For better understanding of the technical solutions of the present application, the following will be described in detail in conjunction with the drawings of the specification and specific embodiments.
[0058] The scalp massage device is a comb device that uses a motor (also referred to as an electric motor) to rotate a gear to make the comb teeth oscillate to massage the scalp. However, at low temperatures, the motor gear is tightly bonded, the resistance increases, and even stops rotating, causing the user to start the device at low temperatures, the rotation speed decreases, or even stops rotating (which causes the comb teeth to oscillate slowly, or the user thinks that the scalp massage device has a fault or is damaged), resulting in a poor user experience.
[0059] Therefore, based on the shortcomings of the above low-temperature start control method, the low-temperature start control circuit of the present application is proposed: by using the temperature detection unit to collect the temperature signal of the temperature detection area, and then based on the temperature signal to control the heating control unit to heat the temperature heating area of the scalp massage device, and after the heating processing, control the motor control unit to start, that is, control the scalp massage device to complete the low-temperature start control, thereby avoiding the phenomenon that the motor gear is tightly bonded at low temperature, which causes the device to not work normally. This low-temperature start control circuit uses the heating control unit to heat the temperature heating area of the scalp massage device to reduce the impact of low temperature on the start of the scalp massage device, thereby improving the effect of low-temperature start control of the scalp massage device.
[0060] Based on this, the embodiment of the present application provides a low-temperature start control circuit, which is described with reference to Figure 1 , Figure 1 The figure is a framework diagram of the first embodiment of the low-temperature start control circuit of the present application.
[0061] With reference to Figure 1 , the present application provides a low-temperature start control circuit applied to a scalp massage device, which comprises:
[0062] A temperature detection unit 10 is arranged in the temperature detection area of the scalp massage device, and the temperature detection unit 10 is used to collect the temperature signal KT of the temperature detection area;
[0063] A control chip unit 20 is connected to the temperature detection unit 10 through a temperature collection end A0, and the control chip unit 20 is used to determine the control signal based on the temperature signal KT collected by the temperature detection unit 10;
[0064] A heating control unit 30 is arranged in the temperature heating area of the scalp massage device, and the heating control unit 30 is connected to the first control end A1 of the control chip unit 20, and the heating control unit 30 is used to perform heating processing based on the control signal sent by the first control end A1.
[0065] The motor control unit 40 is connected with the second control end A2 of the control chip unit 20, and is used for starting based on the control signal sent by the second control end A2 after the heating treatment.
[0066] In the embodiment, the low-temperature starting control circuit is applied to the starting control of the scalp massage device in low temperature, so as to ensure the normal starting of the scalp massage device in low temperature, and further improve the effect of the low-temperature starting control of the scalp massage device. The temperature detection unit 10 is arranged at the temperature detection area of the scalp massage device, which can be the position causing the starting abnormality of the scalp massage device in low temperature, such as the annular guide rail gear disc 2 of the scalp massage device, or other positions, which are not limited herein. Then, the temperature signal KT of the temperature detection area, i.e. the temperature value of the temperature detection area, is collected by the temperature detection unit 10 and transmitted back to the control chip unit 20, so that the control chip unit 20 can generate the control signal according to the temperature signal KT. The control signal is the instruction for controlling the heating control unit 30 to heat and / or controlling the motor control unit 40 to start working, that is, the temperature of the temperature detection area is used to control the heating control unit 30 to heat the temperature heating area of the scalp massage device and / or control the motor control unit 40 to start (the scalp massage device starts to work) at this time, so as to avoid the influence of low temperature on the starting of the scalp massage device, wherein the temperature heating area is the area of the scalp massage device that needs to be heated, such as heating the annular guide rail gear disc 2 directly based on the low-temperature influence relationship. It is worth noting that the whole control process can be: after the scalp massage device is started, the temperature value is obtained by using the temperature detection unit 10 to determine whether the external environment needs to be heated. If heating is needed, the heating control unit 30 is controlled to start heating, and the temperature is detected in real time by the temperature detection unit 10 (or the heating can be directly turned off after a period of heating and the motor is started, without the need for real-time temperature detection), and when the temperature reaches a certain value, the motor control unit 40 is controlled to start the motor, and if the motor runs normally, the heating of the heating control unit 30 is turned off synchronously. The above is only one control process, and the temperature determination in the whole process can be directly completed in the control chip unit 20, that is, the conventional temperature value determination method can be used.
[0067] In an embodiment, the temperature detection unit 10 can be directly replaced by a sensor which can collect the moving speed of the motor or comb teeth of the scalp massage device, and when it is determined that the moving speed is less than the normally defined minimum moving speed, it is determined that the scalp massage device is in the low-temperature starting state at this time, and then the heating control unit 30 is directly controlled to heat the temperature heating area, and after heating for a preset time, the motor control unit 40 is controlled to complete the low-temperature starting control of the scalp massage device. It is worth noting that the control process of the motor control unit 40 is to normally start when starting the scalp massage device, and when detecting that the moving speed is less than the normally defined minimum moving speed, the motor control unit 40 is started after a time delay. The temperature detection unit 10 can also be absent, and the motor control unit 40 is normally started after a period of heating. Other control logics can also be provided, which are not limited herein.
[0068] In the embodiment, a low-temperature starting control circuit applied to a scalp massage device is provided, which includes a temperature detection unit 10, the temperature detection unit 10 is arranged at a temperature detection area of the scalp massage device, and the temperature detection unit 10 is used to collect a temperature signal KT of the temperature detection area; a control chip unit 20, a temperature collection end A0 of the control chip unit 20 is connected with the temperature detection unit 10, and the control chip unit 20 is used to determine a control signal based on the temperature signal KT collected by the temperature detection unit 10; a heating control unit 30, the heating control unit 30 is arranged at a temperature heating area of the scalp massage device, and the heating control unit 30 is connected with a first control end A1 of the control chip unit 20, and the heating control unit 30 is used to perform heating processing based on the control signal sent by the first control end A1; and a motor control unit 40, the motor control unit 40 is connected with a second control end A2 of the control chip unit 20, and the motor control unit 40 is used to perform starting based on the control signal sent by the second control end A2 after the heating processing. The low-temperature starting control circuit collects the temperature signal KT of the temperature detection area by using the temperature detection unit 10, and then controls the heating control unit 30 to perform heating processing on the temperature heating area of the scalp massage device based on the temperature signal KT, and controls the motor control unit 40 to start after the heating processing, that is, controls the scalp massage device to complete the low-temperature starting control, thereby avoiding the phenomenon that the motor gear is tightly adhered during low-temperature starting due to the influence of the low-temperature environment, and cannot work normally. The low-temperature starting control circuit reduces the influence of low temperature on the starting of the scalp massage device by using the heating control unit 30 to perform heating processing on the temperature heating area of the scalp massage device, thereby improving the effect of the low-temperature starting control of the scalp massage device.
[0069] Further, based on the first embodiment of the present application, a second embodiment of the low-temperature starting control circuit of the present application is provided, which refers to Figure 2 , Figure 2A connection diagram of a temperature detection unit in the low-temperature starting control circuit of the application is shown in FIG. 1. The temperature detection unit 20 comprises:
[0070] A temperature detection chip T is arranged in the temperature detection area. A temperature output terminal T1 of the temperature detection chip T is connected with a temperature collection terminal A0.
[0071] A first resistor R1 has a first terminal connected with a temperature power supply VCC1 and a second terminal connected with the temperature output terminal T1.
[0072] A second resistor R2 has a first terminal connected with the temperature output terminal T1 and a second terminal grounded.
[0073] Further, referring to FIG. 2, Figure 3 , Figure 3 Another connection diagram of the temperature detection unit in the low-temperature starting control circuit of the application is shown in FIG. 2. The temperature detection unit 10 further comprises:
[0074] A temperature comparator D has a first input terminal connected with the temperature output terminal T1, a second input terminal connected with a standard temperature signal BT, and an output terminal connected with the temperature collection terminal A0.
[0075] In the embodiment, the temperature detection unit 20 mainly detects the temperature value of the temperature detection area by arranging the temperature detection chip T in the temperature detection area, wherein the temperature detection chip T can be an NTC (Negative Temperature Coefficient) temperature sensor or the like, and further transmits the temperature value of the temperature detection area to the temperature collection end A0 through the temperature output end T1 of the temperature detection chip T, so as to determine whether the low temperature state exists in the control chip unit 20, and determine whether the heating needs to be performed. It is worth noting that the connection mode of other ports of the temperature detection chip T is not described one by one, and the above connection mode is only one connection mode of the temperature detection unit 20, and the connection mode of the temperature detection unit 20 is not limited herein, as long as the temperature value of the temperature detection area can be collected. Further, in order to reduce the workload of the control chip unit 20, a temperature comparator D can be arranged in the temperature detection unit 20, wherein the temperature comparator D can be a simple numerical comparator (such as a commonly used numerical comparator operational amplifier), at this time, the temperature value output by the temperature detection chip T is a, and the numerical value of the standard temperature signal BT is b (the highest temperature of the low temperature state is set, and the temperature lower than the temperature is determined as the low temperature state), and then the size relationship between a and b is compared to output different levels, for example, a is less than b, and the output end of the temperature comparator D outputs a high level, so that the control chip unit 20 can know that the low temperature state exists at this time, and the heating needs to be started, that is, the heating control unit 30 is controlled to perform the heating, on the contrary, a is greater than or equal to b, and the output end of the temperature comparator D outputs a low level, so that the control chip unit 20 can know that the normal temperature state exists at this time, and the heating does not need to be started, that is, the motor control unit 40 is controlled to start normally, so as to accurately and efficiently complete the low temperature starting process.
[0076] In an embodiment, referring to Figure 4 , Figure 4 is a connection diagram of the heating control unit in the low temperature starting control circuit of the application, the heating control unit 30 comprises:
[0077] a heating device H, the heating device H is arranged in the temperature heating area, and the heating power end H1 of the heating device H is connected with the heating power VCC2;
[0078] a first capacitor C1, a first end of the first capacitor C1 is connected with the heating power VCC2, and a second end of the first capacitor C1 is connected with the heating control end T2 of the heating device T;
[0079] a first diode D1, a cathode of the first diode D1 is connected with the heating power VCC2, and an anode of the first diode D1 is connected with the heating control end T2 of the heating device T;
[0080] The first switch tube Q1 has a first end connected to the heating control end T2, and a second end grounded.
[0081] The third resistor R3 has a first end connected to the third end of the first switch tube Q1, and a second end grounded.
[0082] The fourth resistor R4 has a first end connected to the first end of the third resistor R3, and a second end connected to the first control end A1.
[0083] In the embodiment, the heating control unit 30 mainly avoids the influence of low-temperature starting by setting the heating device H in the temperature heating area to heat the temperature heating area, where the heating device H can be a heating resistance wire, a heating resistance, or a resonant heating circuit, etc. The heating control is mainly controlled by the heating control signal KH of the control chip unit 20. When the heating control signal KH is high, the first switch tube Q1 is controlled to be cut off, and the heating device H does not work. When the heating control signal KH is low, the first switch tube Q1 is controlled to be turned on, and the heating device H works to heat the temperature heating area. That is, the heating control of the temperature heating area can be realized based on the control logic of the first switch tube Q1 and the high and low of the heating control signal KH, and then the motor control unit 40 can be started after the temperature heating area is heated, so as to avoid the defect of low-temperature starting of the scalp massage device.
[0084] In an embodiment, referring to Figure 5 , Figure 5 Fig. 4 is a connection diagram of a motor control unit in the low-temperature starting control circuit of the application. The motor control unit 40 includes:
[0085] The motor M has a working power supply end M1 connected to the working power supply VCC3.
[0086] The second capacitor C2 has a first end connected to the working power supply VCC3, and a second end connected to the working control end M2 of the motor M.
[0087] The second diode D2 has a cathode connected to the working power supply VCC3, and an anode connected to the working control end M2 of the motor M.
[0088] The second switch tube Q2 has a first end connected to the working control end M2, and a second end grounded.
[0089] The fifth resistor R5 has a first end connected to the third end of the second switch tube Q2, and a second end grounded.
[0090] The sixth resistor R6 has a first end connected to the first end of the fifth resistor R5 and a second end connected to the second control end A2.
[0091] Further, referring to Figure 6 , Figure 6 is another connection diagram of the motor control unit in the low-temperature starting control circuit, and the motor control unit 40 further includes:
[0092] The delay timer Y has a delay control end Y1 connected to the second control end A2 and a delay output end Y2 connected to the second end of the sixth resistor R6.
[0093] In the embodiment, the motor control unit 40 mainly controls the operation of the scalp massage device, such as the movement of the comb teeth, by the motor M, which can be a common DC motor. The motor M is controlled by the starting control signal KM of the control chip unit 20, for example, when the starting control signal KM is at a high level, the second switch tube Q2 is controlled to be cut off, and the motor M does not work; when the starting control signal KM is at a low level, the second switch tube Q2 is controlled to be turned on, and the motor M works to start the scalp massage device. That is, the low-temperature starting control of the scalp massage device can be realized based on the control logic of the second switch tube Q2 and the high and low of the starting control signal KM, so as to avoid the defects of the low-temperature starting of the scalp massage device. Further, the motor control unit 40 further includes a delay timer Y (such as a normal level delay device), that is, the starting control signal KM output by the second control end A2 is directly controlled by the delay timer Y, for example, when the starting control signal KM is at a high level, the delay timer Y outputs a high level and jumps to a low level after a period of time, the second switch tube Q2 is controlled to be cut off, and the motor M does not work, and the second switch tube Q2 is controlled to be turned on after a period of time, and the motor M works; when the starting control signal KM is at a low level, the delay timer Y outputs a low level, the second switch tube Q2 is controlled to be turned on, and the motor M works. That is, only the jump time of the high level to the low level needs to be set to complete the automatic control, so as to improve the intelligence of the low-temperature starting of the whole scalp massage device.
[0094] In an embodiment, referring to Figure 7 , Figure 7 is a connection diagram of the control chip unit in the low-temperature starting control circuit, and the control chip unit 20 includes a microcontroller U1, a third capacitor C3 and a fourth capacitor C4. The chip power supply end VCC of the microcontroller U1 is connected to the chip power supply VCC4. The first end of the third capacitor C3 is connected to the chip power supply VCC4, and the second end of the third capacitor C3 is grounded. The first end of the fourth capacitor C4 is connected to the chip power supply VCC4, and the second end of the fourth capacitor C4 is grounded.
[0095] In the embodiment, the control chip unit 20 comprises a microcontroller U1 (which can also be a simple single-chip microcomputer, etc.), and the whole microcontroller U1 is powered by the chip power supply VCC4 to ensure the normal operation of the microcontroller U1. It is worth noting that the microcontroller U1, the motor M, the heating device H and the temperature detection chip T are only connected to the ports used, and the port connection relationship of the ports not used or directly acting in the application is not described, such as the ground port, reset port, etc. of the microcontroller U1, the motor M, the heating device H and the temperature detection chip T, and the power supplies of the above, such as the temperature power supply VCC1 and the heating power supply VCC2, can select to use the same power supply, or use the power supply after voltage division or voltage stabilization processing. The actual determination is made according to the power supply object requirement. Of course, the whole low-temperature starting control circuit can also only comprise the heating control unit 30 and the motor control unit 40, that is, the scalp massage device is directly started after starting the heating control unit 30 for a period of time, and then the motor control unit 40 is started, and the heating control unit 30 is closed at the same time, so as to improve the effect of low-temperature starting control of the scalp massage device.
[0096] Based on the first embodiment and / or the second embodiment of the low-temperature starting control circuit, the application also provides a scalp massage device, which comprises the low-temperature starting control circuit described above.
[0097] It is worth noting that according to the scalp massage device of the embodiment of the application, the scalp massage device collects the temperature signal of the temperature detection area by using the temperature detection unit, and then controls the heating control unit to heat the temperature heating area of the scalp massage device based on the temperature signal, and controls the motor control unit to start after the heating treatment, that is, controls the scalp massage device to complete the low-temperature starting control, so as to avoid the phenomenon that the motor gear is tightly adhered to cause the normal work to be unable to be performed at the low-temperature starting time due to the influence of the low-temperature environment. This low-temperature starting control circuit heats the temperature heating area of the scalp massage device by the heating control unit, thereby reducing the influence of the low temperature on the starting of the scalp massage device, and thereby improving the effect of low-temperature starting control of the scalp massage device.
[0098] For example, referring to Figure 8 , Figure 8As shown in Fig. 1, the structure schematic diagram of the first embodiment of the scalp massage device of the present application, the scalp massage device mainly consists of a device handle 7 and a comb assembly 1, and the control area S1 part of the present application is arranged in the device handle 7, which is mainly the area controlled by the low-temperature starting control circuit of the present application, i.e. the low-temperature starting control circuit can be directly arranged in the area, or the low-temperature starting control circuit is arranged in other areas of the device handle 7, but the area ultimately controlled by the low-temperature starting control circuit is the area, i.e. the temperature detection area of the scalp massage device and the temperature heating area of the scalp massage device. It is worth mentioning that the scalp massage device can also have other component structures or include other structures on the basis of the device handle 7 and the comb assembly 1, which is not limited here.
[0099] The device provided by the present application provides a new low-temperature starting control circuit to ensure the effect of low-temperature starting control. Compared with the prior art, the beneficial effects of the device provided by the present application are the same as those of the low-temperature starting control circuit provided by the above-mentioned embodiment, which will not be repeated here.
[0100] Further, based on the first embodiment of the present application, the second embodiment of the scalp massage device of the present application is proposed, which is described with reference to Figure 9 , Figure 9 As shown in Fig. 2, the structure schematic diagram of the second embodiment of the scalp massage device of the present application, the scalp massage device includes:
[0101] A light guide cover 4, in which a heating device H in the low-temperature starting control circuit is arranged;
[0102] A copper sleeve 3, which is sleeved on the light guide cover 4 and covers the heating device H;
[0103] A ring-shaped guide rail gear disc 2, which is sleeved on the copper sleeve 3;
[0104] A device handle 7, in which the light guide cover 4 is fixed.
[0105] In an embodiment, a temperature detection chip T in the low-temperature starting control circuit is arranged on the light guide cover 4, the copper sleeve 3 or the ring-shaped guide rail gear disc 2.
[0106] In the embodiment, the scalp massage device includes the light guide cover 4, the copper sleeve 3, the ring-shaped guide rail gear disc 2 and the device handle 7, so as to arrange the heating device H in the low-temperature starting control circuit on the light guide cover 4 and heat the ring-shaped guide rail gear disc 2 through the copper sleeve 3, and of course the heating device H can also be directly arranged on the copper sleeve 3 or the ring-shaped guide rail gear disc 2, which is not limited in position. Further, with reference to Figure 10 , Figure 10Fig. 3 is a structural schematic diagram of a third embodiment of the scalp massaging device of the present application, which shows a structure of the ring-shaped guide rail gear disc 2, a structure of the copper sleeve 3, and a structure of the light guide cover 4, the carbon fiber heating wire 5 (one kind of heating device H), and the PCB (Printed Circuit Board) 6. For more details, please refer to Figure 9 In the structure of the control area S1 part, the carbon fiber heating wire 5 is welded on the PCB 6, the PCB 6 is fastened on the device handle 7 by screws, and the light guide cover 4 is also fastened on the device handle 7 by screws. It is worth mentioning that the carbon fiber heating wire 5 can be wound on the light guide cover 4, and the copper sleeve 3 is sleeved on the light guide cover 4, and the ring-shaped guide rail gear disc 2 made of POM (Polyoxymethylene) is sleeved on the copper sleeve 3. At low temperature, the shrinkage deformation of POM is relatively obvious, which causes the matching resistance of the ring-shaped guide rail gear disc 2 and the copper sleeve 3 to be large, resulting in the increase of the rotating resistance, so that the motor M cannot drive the ring-shaped guide rail gear disc 2 to work the comb assembly 1, and the motor M is blocked. Therefore, based on the low-temperature starting control circuit, the carbon fiber heating wire 5 is wound around the light guide cover 4, so that the carbon fiber heating wire 5 and the inner ring of the copper sleeve 3 are in full contact to form a heating mechanism, so that the heat is uniformly transmitted to the ring-shaped guide rail gear disc 2 through the copper sleeve 3, so that the ring-shaped guide rail gear disc 2 avoids shrinkage deformation at low temperature, and the scalp massaging device can work normally at low temperature.
[0107] The above only describes some embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation based on the technical concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
