DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] The first embodiment of the present application is:

[0023] See also Figures 1 to 3 ,in, Figure 1 It is a schematic structural diagram of a hot blowing device for coating according to the first embodiment of the utility model. Figure 2 It is a cross-sectional view of the hot blowing device for coating according to the first embodiment of the utility model. Figure 3 The utility model provides a hot air blowing device for wrapping, which includes a hot air generating component, a housing 101, a sensing component, a power control module 102, a handle 105 and a control switch 106. The sensing component includes a gravity sensor 103 and a wireless transmission module 104. The hot air generating component includes a heating cylinder 107, an insulating cylinder 108, a spiral coil 109, an air blower 110 and a filter 111.

[0024] According to this specific embodiment, the housing 101 is connected to the hot air generating component, the sensing component detects the pick-up and put-down state of the housing 101, the power control module 102 is respectively connected to the sensing component and the hot air generating component, and the power control module 102 controls the power on and off of the hot air generating component according to the signal of the sensing component. The housing 101 is fixed to the outside of the hot air generating component to play a protective role, the hot air generating component is used to emit hot air and can adjust the temperature as needed, the sensing component is used to sense the pick-up and put-down state of the device, the power control module 102 is connected to the power supply, the power supply supplies power to each electrical component, and the power control module 102 controls the power on and off of the power supply according to the signal of the sensing component, thereby controlling the operation of each electrical component.

[0025] Wherein, the gravity sensor 103 is installed on the housing 101 and connected to the wireless transmission module 104; the wireless transmission module 104 is connected to the power control module 102. The gravity sensor 103 is installed on the housing 101 and electrically connected to the wireless transmission module 104. The wireless transmission module 104 transmits the signal sensed by the gravity sensor 103 to the power control module 102 in a wireless manner. The gravity sensor 103 is composed of a micro-electromechanical system (MEMS) acceleration sensor. The sensor contains a tiny mass block and a spring system. The acceleration of the device in the three directions of x, y, and z is measured through the acceleration sensor inside. When the device is in a stationary or stable state, the sensor mainly measures the gravity acceleration of the earth, which is about 9.8 meters per second squared. When the device is picked up or put down, additional acceleration will be generated. These accelerations are superimposed on the acceleration of gravity, causing the total acceleration measured by the sensor to change. The mass block in the acceleration sensor will be displaced due to the inertial force, which will cause the spring to expand and contract, thereby producing a change in resistance or charge. The circuit converts these changes into processable signals. The power control module 102 receives the signal from the circuit and analyzes and judges it. By comparing the changes in the acceleration of the device during the process of picking up and putting it down, the power control module 102 can determine whether the device is picked up or put down, thereby controlling the power on and off of the hot air generating component.

[0026] Secondly, the handle 105 is fixedly connected to the housing 101 and is located below the housing 101; the control switch 106 is installed on the handle 105 and is connected to the power control module 102. The handle 105 is convenient for people to hold, and the control switch 106 is used to control the power control module 102. The power control module 102 adjusts the power of the heater by controlling the current or voltage of the hot air generating component, thereby controlling the temperature of the hot air generating component.

[0027] Meanwhile, the insulating cylinder 108 is fixedly connected to the housing 101 and is located inside the housing 101; the heating cylinder 107 is fixedly connected to the insulating cylinder 108 and is located inside the insulating cylinder 108; the spiral coil 109 is located between the heating cylinder 107 and the insulating cylinder 108; and the air blower 110 is located inside the heating cylinder 107. The insulating cylinder 108 and the housing 101 play a double protection role. The heating cylinder 107, the spiral coil 109 and the air blower 110 all adopt the heating cylinder 107, the spiral coil 109 and the air blower 110 disclosed in the announcement number CN203851952U. The spiral coil 109 and the air blower are both controlled by the power control module 102 to control the current or voltage, and are used to emit hot air. The material is made of steel, which is not easy to be damaged and has a longer service life.

[0028] In addition, the filter 111 is detachably connected to the housing 101 and is located at the air inlet of the housing 101. The filter 111 is connected to the air inlet of the housing 101 by bolts to prevent dust from entering and promote a better hot air blowing effect.

[0029] Using a hot air blowing device for coating according to the present embodiment, the gravity sensor 103 senses the acceleration of the shell 101, and uploads the signal to the power control module 102 through the wireless transmission module 104. The power control module 102 determines whether the shell 101 is in a picked up or put down state according to the signal. If it is in a picked up state, the air blower 110 and the spiral coil 109 are powered on to blow out hot air for use. If it is in a put down state, the air blower 110 and the spiral coil 109 are powered off to stop using. The intelligent induction type automatic power on and off coating hot air blowing device can significantly improve the convenience and safety of the coating process, reduce the operating difficulty and safety risks of employees, and has broad application prospects.

[0030] The second embodiment of the present application is:

[0031] Based on the first embodiment, please refer to Figure 4 and Figure 5 ,in, Figure 4 It is a structural schematic diagram of the sensing component of the second embodiment of the utility model. Figure 5 2 is a connection block diagram of the sensing component of the second embodiment of the utility model. The sensing component of this embodiment includes a placement tube 201 and a contact sensor 202.

[0032] According to this specific embodiment, the placement tube 201 is used to place the housing 101; the contact sensor 202 is located inside the placement tube 201 and is connected to the power control module 102. The inner diameter of the placement tube 201 matches the housing 101 and is used to place the device. The contact sensor 202 is installed inside the placement tube, and the contact sensor 202 is connected to the power control module 102 via a power cord. The contact sensor 202 is usually composed of a metal probe and a housing 101. The probe is a component that directly physically contacts the object being tested. When the probe is in physical contact with the object being tested, it will generate corresponding signal changes according to the characteristics of the object being tested (such as temperature, pressure, etc.), and the signal changes detected by the probe will be transmitted to the power control module 102.

[0033] When using a hot-blowing device for coating according to the present embodiment, contact sensing can also be used to determine the status of the device. After the hot-blowing is finished, the shell 101 is placed in the placement tube 201. At this time, the outer frame touches the contact sensor 202, and a signal is uploaded to the power control module 102. The power control module 102 controls the air blower 110 and the spiral coil 109 to cut off the power and turn off the hot-blowing. When in use, pick up the shell 101, and the contact sensor 202 uploads a signal to the power control module 102. The power control module 102 controls the air blower 110 and the spiral coil 109 to turn on the power and start hot-blowing. The intelligent inductive automatic power on and off coating hot-blowing device can significantly improve the convenience and safety of the coating process, reduce the operating difficulty and safety risks of employees, and has broad application prospects.

[0034] The third embodiment of the present application is:

[0035] Based on the second embodiment, please refer to Figure 6 ,in, Figure 6 This is a flowchart of the steps of the hot air blowing control method for coating according to the third embodiment of the utility model. A hot air blowing control method for coating according to this embodiment includes the following steps:

[0036] S301: When the device is picked up, the sensing component detects a change in gravity or a change in contact state and sends a signal to the power control module 102;

[0037] S302: After receiving the signal, the power control module 102 controls the hot air generating component to be powered on to generate hot air;

[0038] S303: When the device is put down, the sensing component detects a change in gravity or a change in contact state again, and sends a power-off signal to the power control module 102;

[0039] S304: The power control module 102 controls the hot air generating component to cut off power and stop generating hot air.

[0040] Specifically, the housing 101 is picked up by the handle 105, that is, the entire device is picked up. At this time, the acceleration of the housing 101 can be sensed by the gravity sensor 103, and the signal can be uploaded to the power control module 102 through the wireless sensor module to determine whether the device is in the state of picking up and putting down. The contact sensor 202 can also be sensed, and the power controller module can determine whether the device is in the state of picking up and putting down. At this point, when the device is picked up, the power control module 102 receives the signal and controls the hot air generating component to be powered on to generate hot air; when the device is put down, the power control module 102 controls the hot air generating component to be powered off to stop generating hot air.
