[0041] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0043] Currently, due to the presence of moisture in the oral cavity, when the scanning head of the intraoral scanner (3D scanner) is placed in the oral cavity for scanning, the optical lens on the scanning head will fog up due to the moisture in the oral cavity, and the image formed by the subsequent optical camera will become blurred, causing abnormal operation of the 3D scanner.

[0044] In response to the above technical problems, an embodiment of the present disclosure provides a scanning device, which includes a scanning head, a processor and a radiator. The heat generated by the processor itself is used to directly assist in heating the scanning head. At the same time, the temperature of the scanning head is controlled in combination with the dynamic frequency modulation function of the processor, and the defog function of the scanning head is turned on or maintained. Therefore, not only can the lens be heated to remove fog, thereby preventing fog from interfering with the operation of the scanning device and improving the scanning effect, but also this method of recycling the heat energy generated by the processor does not increase the power consumption of the scanning device compared to directly using a heating resistor to heat the scanning head. This is both economical and environmentally friendly, and can also greatly reduce the power consumption of the heating resistor, while extending the use time of the scanning device and the battery-powered device in the scanning device.

[0045] The invention is described in detail through one or more of the following embodiments.

[0046] Figure 1 This is a schematic diagram of the structure of a scanning device provided in an embodiment of the present disclosure, wherein the scanning device includes a scanning head, a processor, and a radiator, wherein:

[0047] The processor is used to obtain the current first temperature of the lens in the scanning head, and adjust the current operating frequency to the target operating frequency according to the first temperature and the temperature threshold.

[0048] The heat sink is used to transfer the heat generated by the processor when operating at a target operating frequency to the lens to adjust the temperature of the lens.

[0049] Understandable, see Figure 2, the heat sink 3 is connected to the scanning head 1 and the processor 2 respectively. The scanning head 1 includes a lens 10, which can be an optical lens. One end of the heat sink 3 is close to the lens 10, and the other end is close to the processor 2. The processor 2 obtains the current temperature of the lens 10, which is recorded as the first temperature. The processor 2 adjusts its own operating frequency according to the first temperature and the preset temperature threshold to control the temperature of the lens 10 through the heat sink 3. Specifically, the processor 2 can adjust the current operating frequency to the target operating frequency. The current operating frequency and the target operating frequency are not fixed, that is, the operating frequency of the processor 2 can be increased or decreased. The adjustable range of the normal operating frequency of the processor 2 can be 900MHz to 1200MHz, and the current operating frequency and the target operating frequency are both within this adjustment range. The processor 2 generates heat when working at the target operating frequency, that is, the processor 2 adjusts its own power consumption through the dynamic frequency modulation function. The different power consumption of the processor 1 emits different heat, which will affect the temperature of the heat sink 3, and then the heat sink 3 transfers the generated heat to the lens 10 to control the temperature of the lens 10.

[0050] Optionally, the temperature threshold includes a first threshold and a second threshold, wherein the first threshold is the starting temperature at which the scanning head maintains a defogger function, the second threshold is the ending temperature at which the scanning head maintains a defogger function, and the first threshold is less than the second threshold.

[0051] It can be understood that the temperature threshold includes a first threshold and a second threshold, the first threshold is less than the second threshold, the first threshold and the second threshold constitute a preset temperature range of the lens 10, the lens 10 has a defogging function within the preset temperature range, and there is also a target temperature in the preset temperature range, the target temperature refers to the temperature at which the lens 10 has the best defogging function, specifically, the first threshold can be understood as the starting temperature when the scanning head 1 has the defogging function, that is, the lens 10 starts to have the defogging function after the temperature reaches the first threshold, and the second threshold can be understood as the termination temperature when the scanning head 1 has the defogging function, that is, the lens 10 does not have the defogging function when the temperature exceeds the second threshold or is lower than the first threshold. For example, the first threshold is 40 degrees, the second threshold is 60 degrees, the target temperature is 50 degrees, the preset temperature range is 40 degrees to 60 degrees, and the defogging effect is different at different temperatures of the lens 10 within the preset temperature range.

[0052] Optionally, the processor is configured to:

[0053] Determine whether the first temperature is less than a first threshold value. If the first temperature is less than the first threshold value, increase the current operating frequency of the processor to the first operating frequency. If the first temperature is not less than the first threshold value, when the first temperature is greater than the second threshold value, lower the current operating frequency to the second operating frequency. Determine the first operating frequency or the second operating frequency as the target operating frequency to adjust the first temperature to the target temperature, wherein the target temperature is greater than the first threshold value and less than the second threshold value. wherein the first operating frequency is higher than the second operating frequency.

[0054] It is understandable that after the processor 2 obtains the first temperature, it will determine whether the first temperature is less than the first threshold value. If the first temperature is less than the first threshold value, it means that the temperature of the lens 10 is too low. In this case, the processor 2 automatically increases the current operating frequency to the first operating frequency to increase power consumption. If the first temperature is not less than the first threshold value, it means that the temperature of the lens 10 may be too high or may be within the preset temperature range. In this case, it continues to determine whether the first temperature is greater than the second threshold value. If the first temperature is greater than the second threshold value, it means that the temperature of the lens 10 is too high. The processor 2 automatically lowers the current operating frequency to the second operating frequency, wherein the first operating frequency is higher than the second operating frequency. Based on the above example, the first operating frequency is 1200MHz and the second operating frequency is 900MHz. Alternatively, the processor 2 can also first determine whether the first temperature is greater than the second threshold value. If the first temperature is less than the second threshold value, it can then determine whether the first temperature is less than the first threshold value. The specific order of determining the first temperature and the temperature threshold value is not limited and can be selected according to needs. After the processor 2 completes the temperature adjustment, it determines the first operating frequency or the second operating frequency as the target operating frequency, and adjusts its own power consumption by operating at the target operating frequency. The heat dissipated by the power consumption is transferred to the lens 10 through the radiator 3 to adjust the temperature of the lens 10 to the target temperature, thereby ensuring the best defogging effect.

[0055] Optionally, the scanning device further includes a heating component, and the processor is configured to:

[0056] According to the first temperature, the first threshold and the second threshold, the current operating frequency is adjusted to the target operating frequency, and / or the current pulse width duty cycle is adjusted to the target duty cycle, wherein the target duty cycle is used to control the power consumption of the heating component; the heating component is connected to the circuit where the processor is located, and the heating component is used to operate based on the target duty cycle transmitted by the circuit to transfer heat to the scanning head.

[0057] For example, see Figure 2 , Figure 2The scanning device shown also includes a heating component 11. The heating component 11 can be arranged in the scanning head 1, close to the back of the lens 10, and is used to provide heat for the lens 10. Specifically, the heating component 11 can be a heating resistor. At the same time, the heating component 11 is connected to the circuit 21 where the processor 2 is located. The circuit 21 can be in the form of a circuit board, and can be specifically connected to the circuit board where the processor 2 is located, so that the processor 2 can control the power consumption of the heating component 11 through the circuit board and adjust the temperature of the lens 10 through the heating component 11.

[0058] It is understandable that when the processor 2 determines the size of the first temperature, the first threshold and the second threshold, that is, determines whether the temperature of the lens 10 is too low or too high, in addition to adjusting its own operating frequency, it can also adjust the pulse width duty cycle (hereinafter referred to as the pulse duty cycle) to control the loss of the heating component 11. Specifically, the current duty cycle can be adjusted to the target duty cycle, that is, the heating component can be turned on and off by the pulse duty cycle. For example, the heating component 11 can be turned on with a pulse duty cycle output and can be turned off without a duty cycle output. The heating component 11 in the off state will not transfer heat to the lens 10.

[0059] Optionally, when the first temperature is less than the first threshold, the processor is configured to:

[0060] The current operating frequency is gradually increased to the first operating frequency, and the first operating frequency is determined as the target operating frequency; after the processor operates at the target operating frequency for a first preset time, the current second temperature of the lens is obtained; when the second temperature is still less than the first threshold, the current pulse width duty cycle is adjusted to the first duty cycle to increase the power consumption of the heating component, and the first duty cycle is determined as the target duty cycle.

[0061] It is understandable that when the first temperature is less than the first threshold, that is, when the temperature of the lens 10 is low, the processor 2 gradually increases the current operating frequency to the first operating frequency to increase power consumption. The value of the operating frequency adjusted each time is not limited. For example, it increases by 100 MHz each time. After the operating frequency of the processor 2 is increased, the temperature of the radiator 3 will increase, and then the temperature of the lens 10 will be increased through the radiator 3. If the processor 2 adjusts the operating frequency to the first operating frequency, that is, adjusts the operating frequency to the maximum, and works at the first operating frequency for the first preset time, so as to ensure that the radiator 3 transfers heat to the lens 10, so that the lens 10 heats up, in this case, the current temperature of the lens 10 is obtained, which is recorded as the second temperature. At this time, the second temperature is higher than the first temperature, and then it is determined whether the second temperature is still less than the first threshold, that is, the operating frequency of the processor 2 is adjusted to the maximum, and the temperature of the lens 10 still cannot reach the first threshold to turn on the defog function, the processor 2 automatically adjusts the current duty cycle to the first duty cycle to increase the power consumption of the heating component 11, so that the temperature of the lens 10 exceeds the first threshold until the target temperature; or, if the second temperature is greater than the first threshold and less than the target temperature, that is, after the operating frequency of the processor 2 is adjusted to the maximum, the temperature of the lens 10 turns on the defog function but still does not reach the target temperature, resulting in poor defog effect, in this case, the processor 2 automatically adjusts the current duty cycle to the first duty cycle to increase the power consumption of the heating component 11, so that the temperature of the lens 10 reaches the target temperature, with the best defog effect.

[0062] A feasible example is that the target temperature is 50°C, and the normal operating frequency range of the processor 2 is 900MHz to 1200MHz. When the first temperature is less than the first threshold, the first threshold is 40°C, that is, when the measured temperature of the lens 10 deviates from the target temperature by -10°C, the defog function of the lens 10 is affected. In this case, the processor 2 automatically increases the operating frequency to increase power consumption and increase heat, so that the temperature of the radiator 3 increases, and then the temperature of the lens 10 increases. When the operating frequency of the processor 2 is adjusted to 1200MHz (the first operating frequency), the second temperature of the lens 10 still does not reach the target temperature of 50°C. The processor 2 adjusts the pulse width duty cycle to increase the power consumption of the heating component 11, so that the temperature of the lens 10 is maintained at the target temperature. That is, when the lens temperature is lower than the target temperature, the processor will first increase the operating frequency and then adjust the pulse duty cycle.

[0063] Optionally, when the first temperature is greater than the second threshold, the processor is further configured to:

[0064] The current pulse width duty cycle is adjusted to a second duty cycle to reduce the power consumption of the heating component, and the second duty cycle is determined as the target duty cycle; after the heating component works at the target duty cycle for a second preset time, the current third temperature of the scanning head is obtained; when the third temperature is still greater than the second threshold, the current operating frequency is gradually lowered to the second operating frequency, and the second operating frequency is determined as the target operating frequency.

[0065] It is understandable that when the first temperature is greater than the second threshold, that is, when the temperature of the lens 10 is too high, the processor 2 automatically adjusts the current duty cycle to the second duty cycle to reduce the power consumption of the heating component 11, so that the measured temperature of the lens 10 is lower than the second threshold. Specifically, the pulse duty cycle output of the heating component 11 can be turned off. After the heating component 11 works at the target duty cycle for the second preset time, that is, to ensure that the heating component 11 no longer transfers heat to the lens 10 or reduces the heat transferred to the lens 10 to reduce the temperature of the lens 10, in this case, the processor 2 obtains the current temperature of the lens 10, which is recorded as the third temperature. At this time, the third temperature is lower than the first temperature. Then, it is determined whether the third temperature is still greater than the second threshold. If the third temperature is still greater than the second threshold, or if the third temperature is less than the second threshold and greater than the target temperature, the processor 2 gradually lowers the current operating frequency until the second operating frequency, and determines the second operating frequency as the target operating frequency, reduces the temperature of the radiator 3, and then reduces the temperature of the lens 10, so that the temperature of the lens 10 is maintained at the target temperature, with the best defogging effect.

[0066] Another feasible example is that the target temperature is 50°C, and the normal operating frequency range of processor 2 is 900MHz to 1200MHz. When the first temperature is greater than the second threshold value, the second threshold value is 60°C, that is, when the second threshold value deviates from the target temperature by +10°C, the temperature of lens 10 is too high, and processor 2 first turns off the pulse duty cycle output that controls the heating component 11. If the third temperature of lens 10 is still higher than the target temperature or the second threshold value after the heating component 11 is turned off, processor 2 gradually reduces its operating frequency until the operating frequency is reduced to 900MHz (second operating frequency) to reduce the temperature of lens 10 and keep the temperature of lens 10 at the target temperature. That is, when the lens temperature is higher than the target temperature, the processor will first adjust the pulse duty cycle and then lower the operating frequency.

[0067] Optionally, the scanning device further includes a first heat-conducting component and a second heat-conducting component, wherein the first heat-conducting component is used to realize heat transfer between the processor and the heat sink; and the second heat-conducting component is used to realize heat transfer between the heat sink and the scanning head.

[0068] For example, see Figure 2The scanning device further includes a first heat-conducting component 20 and a second heat-conducting component 12. The first heat-conducting component 20 is disposed between the radiator 3 and the processor 2 to achieve heat transfer between the processor 2 and the radiator 3. The first heat-conducting component 20 may be thermal grease. The heat transfer between the radiator 3 and the processor 2 is achieved through the thermal grease. The second heat-conducting component 12 is disposed between the radiator 3 and the lens 10 to achieve heat transfer between the radiator 3 and the lens 10. The second heat-conducting component 12 may be thermal grease. The thermal grease between the radiator 3 and the lens 10 is achieved through the thermal grease.

[0069] Optionally, the scanning device further includes a temperature sensor, which is used to measure the temperature of the scanning head; the temperature sensor is connected to a circuit where the processor is located, and the processor obtains the temperature of the scanning head through the temperature sensor.

[0070] For example, see Figure 2 The scanning device also includes a temperature sensor 13 , which can be closely attached to the back of the lens 10 together with the heating component 11 . The temperature sensor 13 is also connected to the circuit 20 of the processor 2 , and the processor 2 obtains the temperature of the lens 10 in real time through the temperature sensor 13 .

[0071] It is understandable that the scanning device also includes a fan, and the heat of the processor 2 can also be blown to the lens 10 through the built-in fan to remove the fog on the lens 10.

[0072] For example, see Figure 3 The scanning device includes a scanning head 1 and a host 4, and the scanning head 1 and the host 4 can be detachably connected. When the scanning head 1 and the host 4 are assembled together, the lens 10 is located in the scanning head 1, the processor 2 is located in the host 4, and the processor 2 and the lens 10 transfer heat through the radiator 3. Specifically, the radiator 3 includes a heat-conducting bracket 30 located in the scanning head 1 and a heat-dissipating skeleton 31 located in the host 4. The heat-conducting bracket 30 and the heat-dissipating skeleton 31 are overlapped together, the processor 2 is connected to the heat-dissipating skeleton 31 through the first heat-conducting component 20, and the lens 10 is connected to the heat-conducting bracket 30 through the second heat-conducting component 12.

[0073] The scanning device provided by the embodiment of the present disclosure can utilize the heat generated by the processor itself through circulation to heat the lens of the scanning head, remove the fog from the lens, save power consumption, and be economical and environmentally friendly. At the same time, the lens carries a temperature sensor. The processor can obtain the temperature of the lens in real time through the temperature sensor, and dynamically adjust its own operating frequency and pulse duty cycle according to the temperature of the lens. The pulse duty cycle is used to control the opening and closing of the heating component to realize closed-loop control of the lens temperature, effectively reduce power consumption, and increase the service life of battery-powered equipment.

[0074] Based on the above embodiments, Figure 4 The flow chart of the temperature adjustment method provided by the embodiment of the present disclosure is applied to the processor 2 in the scanning device, specifically including the following steps: Figure 4 Steps S401 to S402 shown:

[0075] S401, obtaining a current first temperature of a lens in a scanning head.

[0076] S402, adjusting the current operating frequency to the target operating frequency according to the first temperature and the temperature threshold, and then operating at the target operating frequency and generating heat, so that the heat sink in the scanning device transfers the heat to the lens, thereby completing the temperature adjustment of the lens.

[0077] It is understandable that the specific implementation steps of the above S401 to S402 refer to the above embodiments and are not described in detail here.

[0078] The temperature threshold includes a first threshold and a second threshold, wherein the first threshold is the starting temperature at which the scanning head maintains the defogger function, the second threshold is the ending temperature at which the scanning head maintains the defogger function, and the first threshold is less than the second threshold.

[0079] Optionally, in S402, adjusting the current operating frequency to the target operating frequency according to the first temperature and the temperature threshold may be implemented through the following steps:

[0080] Determine whether the first temperature is less than a first threshold value. If the first temperature is less than the first threshold value, increase the current operating frequency of the processor to the first operating frequency. If the first temperature is not less than the first threshold value, when the first temperature is greater than the second threshold value, lower the current operating frequency to the second operating frequency. Determine the first operating frequency or the second operating frequency as the target operating frequency to adjust the first temperature to the target temperature, wherein the target temperature is greater than the first threshold value and less than the second threshold value. wherein the first operating frequency is higher than the second operating frequency.

[0081] Wherein, the scanning device also includes a heating component.

[0082] Optionally, in S402, adjusting the current operating frequency to the target operating frequency according to the first temperature and the temperature threshold may be implemented through the following steps:

[0083] According to the first temperature, the first threshold and the second threshold, the current operating frequency is adjusted to the target operating frequency, and / or the current pulse width duty cycle is adjusted to the target duty cycle, wherein the target duty cycle is used to control the power consumption of the heating component.

[0084] Optionally, when the first temperature is less than the first threshold, the current operating frequency is adjusted to the target operating frequency and / or the current pulse width duty cycle is adjusted to the target duty cycle according to the first temperature, the first threshold and the second threshold, which can be specifically achieved by the following steps:

[0085] The current operating frequency is gradually increased to the first operating frequency, and the first operating frequency is determined as the target operating frequency; after the processor operates at the target operating frequency for a first preset time, the current second temperature of the lens is obtained; when the second temperature is still less than the first threshold, the current pulse width duty cycle is adjusted to the first duty cycle to increase the power consumption of the heating component, and the first duty cycle is determined as the target duty cycle.

[0086] Optionally, when the first temperature is greater than the second threshold, the current operating frequency is adjusted to the target operating frequency, and / or the current pulse width duty cycle is adjusted to the target duty cycle according to the first temperature, the first threshold, and the second threshold, which can be specifically achieved by the following steps:

[0087] The current pulse width duty cycle is adjusted to a second duty cycle to reduce the power consumption of the heating component, and the second duty cycle is determined as the target duty cycle; after the heating component works at the target duty cycle for a second preset time, the current third temperature of the scanning head is obtained; when the third temperature is still greater than the second threshold, the current operating frequency is gradually lowered to the second operating frequency, and the second operating frequency is determined as the target operating frequency.

[0088] It is understandable that the specific implementation of the above steps can be found in the above embodiments and will not be described in detail here.
