Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.
[0044] To illustrate the technical solutions described in the present application, the following will be described in detail in combination with specific drawings and embodiments.
[0045] In the related art, in order to ensure the normal operation of the heat-not-burn device and the safety of the user, an infrared detection sensor is usually provided to monitor the insertion of the aerosol substrate. However, when the user is cleaning or maintaining, if a cleaning tool or a maintenance tool such as a cotton swab with a diameter smaller than that of the aerosol substrate is inserted into the heat-not-burn device, the infrared sensor may also be triggered to detect, thereby causing the heating to start.
[0046] To this end, the embodiments of the present application provide a heat-not-burn device to solve the problems in the related art. The heat-not-burn device provided by the present application will be described in detail below in combination with the drawings.
[0047] In combination with Figures 3 to 5 As shown in the drawings, in one or more embodiments, the present application provides a heat-not-burn device 100, which comprises a housing 101, a shielding structure 102, a detection sensor 103 and a heating assembly 104; the housing 101 has a receiving cavity 105 and a detection through hole 106, the receiving cavity 105 has opposite first and second ends 126 and 127; the first end 126 is provided with a receiving opening 107 for inserting the aerosol substrate 200 into the receiving cavity 105, and the detection through hole 106 is in communication with the receiving cavity 105; at least part of the shielding structure 102 is arranged in the receiving cavity 105; the detection sensor 103 is arranged opposite to the detection through hole 106, and the detection sensor 103 is used to detect whether the detection through hole 106 is blocked by the shielding structure 102; the heating assembly 104 is used to heat the aerosol substrate 200 located in the receiving cavity 105; wherein when the aerosol substrate 200 is inserted into the receiving cavity 105, the aerosol substrate 200 can block the detection through hole 106 with the shielding structure 102.
[0048] The heating non-combustion device 100 provided by the embodiments of the present application can make the shielding structure 102 move when the aerosol substrate 200 is inserted into the accommodating cavity 105, so that the shielding structure 102 blocks the detection through hole 106. In this way, when the detection through hole 106 is blocked, the detection sensor 103 detects that the detection through hole 106 is blocked, so that it is determined that the aerosol substrate 200 has been inserted into the accommodating cavity 105 in the current case, that is, when the detection sensor 103 detects that the detection through hole 106 is blocked by the shielding structure 102, it is determined that the aerosol substrate 200 is located in the accommodating cavity 105. When the aerosol cavity substrate is located in the accommodating cavity 105, the detection through hole 106 is blocked by the shielding structure 102, so that the heating assembly 104 heats the aerosol substrate 200. In this way, when a cleaning tool or a maintenance tool with a diameter smaller than that of the aerosol substrate 200 is inserted into the accommodating cavity 105, the shielding structure 102 will not move, so that it will not block the detection through hole 106, and the detection sensor 103 will not detect that the detection through hole 106 is blocked by the shielding structure 102, thereby reducing or avoiding the situation that the heating assembly 104 is started when the aerosol substrate 200 is not inserted into the accommodating cavity 105.
[0049] In some embodiments, the accommodating cavity 105 can be columnar, which is convenient for matching the aerosol substrate 200 in the form of a rod. It can be understood that when the cross section of the aerosol substrate 200 is circular, elliptical or polygonal, the cross section of the accommodating cavity 105 is also in the same shape, so as to facilitate the matching of the accommodating cavity 105 and the aerosol substrate 200.
[0050] Referring to Figure 5 In some embodiments, the shielding structure 102 is close to the accommodating opening 107 and the detection through hole 106 is away from the accommodating opening 107 in the length direction of the accommodating cavity 105. In this way, during the process that the aerosol substrate 200 is inserted into the accommodating cavity 105 from the accommodating opening 107, the aerosol substrate 200 can move the shielding structure 102 to shield the detection through hole 106, so that the detection sensor 103 detects that the detection through hole 106 is blocked, and the heating assembly 104 is started to heat, thereby heating the aerosol substrate 200.
[0051] Referring to Figure 5 In some embodiments, the shielding structure 102 has opposite connecting ends 108 and free ends 109, and the connecting ends 108 are connected to the shell 101. The direction from the connecting end 108 to the free end 109 is non-parallel to the length direction of the accommodating cavity 105. In this way, when the aerosol substrate 200 is inserted into the accommodating cavity 105 from the accommodating opening 107, the aerosol substrate 200 is convenient to contact the shielding structure 102, so that the shielding structure 102 moves.
[0052] In combination withFigure 4 and Figure 5 As shown in FIG. 1, in some embodiments, the connecting end 108 of the shielding structure 102 is close to the second end 127 of the accommodating cavity 105, and the free end 109 is away from the second end 127 in the length direction of the accommodating cavity 105. In this way, in combination with the shielding structure 102 being close to the accommodating opening 107 and the detection through hole 106 being away from the accommodating opening 107, the free end 109 can be driven by the aerosol substrate 200 to move towards the second end 127 of the accommodating cavity 105 to shield the detection through hole 106.
[0053] In some embodiments, the shielding structure 102 is a sheet structure. The sheet structure is used to facilitate the shielding of the detection through hole 106. For example, when the shielding structure 102 shields the detection through hole 106, a light-reflecting layer is arranged on the side of the shielding structure 102 facing the detection through hole 106, which can improve the detection accuracy of the detection sensor 103. The light-reflecting layer can be coated on the shielding structure 102 or fixed on the shielding structure 102 by inlaying. The light-reflecting layer can be a metal sheet, a silver coating or an aluminum coating.
[0054] In some embodiments, the shielding structure 102 is made of silica gel or rubber, which is convenient for manufacturing and beneficial for the elastic deformation of the shielding structure 102. That is, when the aerosol substrate 200 contacts the shielding structure 102, the shielding structure 102 deforms with the gradual insertion of the aerosol substrate 200, and the free end 109 of the shielding structure 102 moves from the position close to the accommodating opening 107 to the position away from the accommodating opening 107, thereby shielding the detection through hole 106. When the aerosol substrate 200 is pulled out of the accommodating cavity 105, the shielding structure 102 made of silica gel or rubber restores to its original state under the action of elasticity, that is, the free end 109 of the shielding structure 102 moves from the position away from the accommodating opening 107 to the position close to the accommodating opening 107, so that the shielding structure 102 no longer shields the detection through hole 106. When the detection sensor 103 detects that the detection through hole 106 is no longer shielded, the heating assembly 104 stops heating.
[0055] It should be noted that in some other possible embodiments, the shielding structure 102 can also be a metal spring, so that the elastic deformation of the metal spring can also be utilized to shield the detection hole 106; and when the aerosol substrate 200 is pulled out of the accommodation cavity 105, the metal spring shielding structure 102 restores to its original shape under the action of elasticity, so that the metal spring no longer shields the detection hole 106, and when the detection sensor 103 detects that the detection hole 106 is no longer shielded, the heating assembly 104 stops heating. It can be understood that the shielding structure 102 is not limited to the scheme of shielding the detection hole 106 by utilizing the elastic deformation of the shielding structure 102 itself and restoring to its original shape when the aerosol substrate 200 is pulled out of the accommodation cavity 105, but the shielding structure 102 can also be cooperated with a torsional spring to shield the detection hole 106, and when the aerosol substrate 200 is pulled out of the accommodation cavity 105, the elastic potential energy of the torsional spring is utilized to restore the shielding structure 102 to its original shape, for example, the connecting end 108 of the shielding structure 102 is rotationally connected with the shell 101, and the torsional spring is arranged between the shielding structure 102 and the shell 101.

By utilizing the light guide assembly 110, the light emitted by the detection sensor 103 can be guided, so as to reduce the loss of light and improve the accuracy of detection.

Referring to Figure 2 As shown in FIG. 1, the outer shell 112 has a second through hole 125, the second through hole 125 is coaxially arranged with the accommodation cavity 105, and the second through hole 125 is in communication with the accommodation cavity 105, so that the aerosol substrate 200 is inserted into the accommodation cavity 105 through the second through hole 125.
[0059] In combination Figures 5 to 7As shown, in some embodiments, the light guide assembly 110 comprises a light leakage prevention member 114 and a light guide mirror 115, the light leakage prevention member 114 has a receiving groove 116, the detection sensor 103 extends into the receiving groove 116, the groove bottom of the receiving groove 116 has a first through hole 117, the first through hole 117 is arranged opposite to the light guide mirror 115, at least part of the structure of the light guide mirror 115 extends into the detection through hole 106; in this way, the light leakage prevention member 114 can reduce light leakage to improve the detection accuracy of the detection sensor 103; and the light guide mirror 115 can realize the conduction of light to improve the detection accuracy. For example, the light leakage prevention member 114 can be a plate-shaped structure; the heat-not-burn device 100 further comprises a circuit board 118, the circuit board 118 is installed on the support 111, for example, the circuit board 118 can be fixedly connected with the support 111 by snap connection or screw connection; and the detection sensor 103 is integrated on the circuit board 118. The material of the light guide mirror 115 can be glass or resin. The circuit board 118 is electrically connected with the heating assembly 104; the light emitted by the detection sensor 103 propagates into the light guide mirror 115 through the first through hole 117, and then propagates out of the light guide mirror 115, after the shielding structure 102 blocks the detection through hole 106, the detection sensor 103 detects that the shielding structure 102 is located at the detection through hole 106, and then the detection sensor 103 makes the heating assembly 104 start through the circuit board 118, that is, the heating assembly 104 is powered on to realize heating of the aerosol substrate 200.
[0060] In combination Figures 5 to 7 As shown, in some embodiments, the light guide assembly 110 further comprises a light guide column 119; in the light path direction of the light emitted by the detection sensor 103, the light guide column 119 is arranged between the light leakage prevention member 114 and the light guide mirror 115. The light guide column 119 is used to guide the light. For example, the light guide column 119 has a light guide through hole 120, the light guide through hole 120 is in communication with the first through hole 117, so that the light emitted by the detection sensor 103 can propagate into the light guide mirror 115 through the first through hole 117 and the light guide through hole 120. The light guide column 119 and the light leakage prevention member 114 can be interference fit by plug-in, or the light guide column 119 and the light leakage prevention member 114 can be fixed by adhesion; and the light guide mirror 115 and the light guide column 119 can be interference fit by plug-in.
[0061] In combination Figures 5 to 7As shown, in some embodiments, the shell 101 comprises a first sub-shell 121 and a second sub-shell 122, the first sub-shell 121 is inserted with the second sub-shell 122; the shielding structure 102 is connected with the first sub-shell 121, and the detection through hole 106 is arranged on the first sub-shell 121. For example, the first sub-shell 121 has an insertion cavity, and the second sub-shell 122 is inserted into the insertion cavity to realize the insertion between the first sub-shell 121 and the second sub-shell 122; it can be understood that after the insertion of the first sub-shell 121 and the second sub-shell 122, the two can be fixed in a interference fit manner, or can be fixed in an adhesive manner.

[0063] Referring to Figure 4 As shown, in some embodiments, the heating assembly 104 is arranged in the accommodation cavity 105, and the heating assembly 104 can comprise a heating net, a heating pipe or a heating wire, which can adopt resistance heating, electromagnetic heating or infrared heating to heat the aerosol substrate 200, which is not limited in the present application. The shape of the heating assembly 104 is approximately cylindrical, and since at least part of the structure of the aerosol substrate 200 is arranged in the heating assembly 104, the size inside the heating assembly 104 should match the shape of the aerosol substrate 200. After the aerosol substrate 200 is inserted into the accommodation cavity 105, the heating assembly 104 can heat the aerosol substrate 200.
[0064] Referring to Figure 5 As shown, in some embodiments, the detection sensor 103 is an infrared distance sensor, a photoelectric sensor or a laser distance sensor, so that different types of sensors can be selected according to the actual application scene. For example, the detection sensor 103 is an infrared distance sensor, before the aerosol substrate 200 is inserted, the shielding structure 102 does not shield the detection through hole 106, and the infrared distance sensor detects a longer distance; when the aerosol substrate 200 is inserted, the shielding structure 102 will bend downward to shield the detection through hole 106 (the movement path of the shielding structure 102 can be referred to the direction of arrow C in Figure 5 Figure 1 As shown, the aerosol substrate is inserted into the heating non-combustion device 100. When the aerosol substrate 200 is pulled out, the shielding structure 102 returns to the initial position, the infrared distance sensor re-detects the longer distance, and then the heating assembly 104 stops heating. Since the shielding structure 102 can completely cover the light guide mirror 115 when the aerosol substrate 200 is inserted, the heating of the aerosol substrate 200 can be achieved. When an object with a diameter smaller than that of the aerosol substrate 200 is inserted, the shielding structure 102 will not be bent and deformed to block the detection through hole 106, so that the situation of triggering heating during cleaning can be reduced or avoided. It should be noted that in the embodiments of the present application, the diameter of the tool used during cleaning or maintenance is smaller than the diameter of the aerosol substrate 200, and when the tool is inserted into the accommodating cavity 105, the shielding structure 102 will not affect the insertion of the tool, that is, the tool will not block the detection through hole 106 of the shielding structure 102.
[0065] The above only describes optional embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
