[0027] In the current market, e-cigarettes have received widespread attention as an emerging alternative to traditional tobacco products. E-cigarettes include disposable e-cigarettes, cartridge e-cigarettes, mechanical e-cigarettes, and heat-not-burn (HnB) e-cigarettes. HnB e-cigarettes deliver nicotine by heating rather than burning tobacco, thereby reducing the harmful substances produced by traditional smoking and lowering health risks. The tobacco stick is one of the key components of HnB e-cigarettes. When using it, it needs to be inserted into the heating chamber or a special insertion port. If the tobacco stick is not inserted properly, the heating element may not be able to heat the tobacco effectively, resulting in uneven heating and affecting the user experience. Some HnB devices have a structure to detect whether the tobacco stick is inserted correctly, but the structure is complex and inconvenient to manufacture.

[0028] This utility model proposes a testing mechanism and an electronic cigarette.

[0029] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment of this utility model, the detection mechanism includes:

[0030] Mounting base 100, the mounting base 100 has a movable cavity 101 for inserting tobacco stick 10, and the mounting base 100 is provided with a connecting cavity 102 communicating with the movable cavity 101;

[0031] Circuit board 200 is disposed on the side of mounting base 100 where connection cavity 102 is provided;

[0032] A emitting assembly 300 is disposed on the side of the circuit board 200 facing the mounting base 100, and the emitting assembly 300 is used to emit light through the connecting cavity 102 into the movable cavity 101; and

[0033] A receiving component 400 is disposed on the side of the circuit board 200 facing the mounting base 100. The receiving component 400 is used to receive light within the connection cavity 102.

[0034] In the technical solution of this utility model, the detection mechanism includes a mounting base 100, on which a movable cavity 101 is formed. A mounting cavity 510 communicating with the movable cavity 101 is provided on one side of the mounting base 100. A circuit board 200 is provided on the outer side of the mounting base 100. A transmitting component 300 and a receiving component 400 are provided on the side of the circuit board 200 facing the mounting base 100. The transmitting component 300 emits light or a signal toward the movable cavity 101, and the light / signal passes through a connecting cavity 102. The receiving component 400 receives reflected light from the movable cavity 101 within the connecting cavity 102. If the tobacco stick 10 is not inserted into the movable cavity 101 or is not fully inserted, the signal received by the receiving component 400 is weak. If the tobacco stick 10 is fully inserted into the movable cavity 101, the signal received by the receiving component 400 is strong. The received light or signal will increase due to reflection from the tobacco stick 10. By setting up the transmitting component 300 and the receiving component 400, the strength of the received signal is used to determine whether the tobacco stick 10 is inserted in place. In addition, the transmitting component 300 and the receiving component 400 are set in a connecting cavity 102, which simplifies the structure and reduces the complexity of the design. It eliminates the need to design and manufacture separate cavities for the transmitting component 300 and the receiving component 400, simplifying the assembly process and reducing manufacturing costs. It also eliminates the need for complex optical path design to connect two separate cavities, making the whole device more compact and facilitating product weight reduction. Furthermore, since the transmitted and received light work in the same connecting cavity 102, signal loss caused by optical path bending or reflection can be reduced, improving the sensitivity and accuracy of detection.

[0035] Specifically, the shape and material of the mounting base 100 are not limited, but the cross-section of its movable cavity 101 is circular for inserting the tobacco stick 10. Preferably, the inner wall of the movable cavity 101 fits against the outer wall of the tobacco stick 10. The inner wall size of the movable cavity 101 is not limited, and a suitable tobacco stick 10 is selected according to different movable cavities 101. The transmitting assembly 300 and the receiving assembly 400 are mounted on the side of the circuit board 200 facing the connecting cavity 102, and the transmitting end of the transmitting assembly 300 and the receiving end of the receiving assembly 400 are located inside the connecting cavity 102 so as to transmit and receive signals through the connecting cavity 102. The emitting component 300 can be an infrared light-emitting diode, and the corresponding receiving component 400 can be a phototransistor. In another embodiment, the emitting component 300 can be a laser diode, and the corresponding receiving component 400 can be a photodiode, photodetector, or reflective photoelectric sensor module to determine whether the tobacco stick 10 is inserted based on the intensity of the received light beam. The emitting component 300 emits light into the movable cavity 101 from within the connecting cavity 102, and the receiving component 400 can effectively detect the light reflected back from the movable cavity 101. If the tobacco stick 10 is not inserted or is not fully inserted into the movable cavity 101, the receiving component 400 can detect the light. The light emitted by the transmitting component 300 is reflected back by the inner wall of the movable cavity 101. Because the mounting base 100 has a low reflectivity, a large amount of light is absorbed, and only a small amount is reflected. This results in a weaker light or signal received by the receiving component 400. Furthermore, when the tobacco stick 10 is not inserted, the emitted light needs to travel radially through the movable cavity 101 to reach the inner wall of the cavity for reflection. This long light travel distance leads to scattering and absorption, reducing the effective brightness reaching the inner wall of the movable cavity 101. After absorption, the amount of light reflected back to the receiving component 400 is further reduced. However, if the movable cavity 101... A tobacco stick 10 is present in the active cavity 101. Due to the smooth surface and high reflectivity of the tobacco stick 10, the emitted light is reflected by the tobacco stick 10 upon reaching the active cavity 101. The reflected light passes through the connecting cavity 102 and reaches the receiving component 400, enhancing the received signal. Furthermore, the tobacco stick 10 is closer to the transmitting component 300 and the receiving component 400 within the active cavity 101, shortening the light travel path and reducing energy loss. In one embodiment, the circuit board 200 is an FPC flexible circuit board 200. The FPC is made of a flexible substrate, which can be bent and folded without affecting its electrical performance, making it suitable for the compact spatial layout in this structure.

[0036] In an embodiment of this utility model, the mounting base 100 includes:

[0037] The cylindrical body 110 has a movable cavity 101 and a first through hole on one side.

[0038] A connecting plate 120 is provided on the outer peripheral wall of the mounting base 100. The connecting plate 120 has a connecting cavity 102 and a second through hole communicating with the connecting cavity 102. The first through hole and the second through hole are connected.

[0039] Specifically, please refer to Figure 2 The mounting base 100 includes a cylindrical body 110 and a connecting plate 120 connected to each other. The cylindrical body 110 has a movable cavity 101 formed along its axial direction. A first through hole is provided through the peripheral wall of the cylindrical body 110, communicating with the movable cavity 101. The shape of the first through hole is not limited. The connecting plate 120 is disposed outside the cylindrical body 110 and close to the first through hole. A second through hole communicating with the first through hole is provided on the connecting plate 120. A connecting cavity 102 is disposed on the connecting plate 120 and connected to the movable cavity 101 through the first and second through holes. The circuit board 200 is located at the end of the connecting plate 120 away from the cylinder 110, and the transmitting component 300 and the receiving component 400 are located on the side of the circuit board 200 facing the connecting plate 120. The emitted light passes through the second through hole and the first through hole in the connecting cavity 102 to reach the movable cavity 101, and is reflected and passes through the first through hole and the second through hole in sequence to reach the receiving component 400. The connection between the connecting plate 120 and the cylinder 110 makes the connection of the circuit board 200 more stable, and also makes the light path transmission and detection results more accurate.

[0040] In one embodiment, the mounting base 100 is injection molded, and the cylinder 110 and the connecting plate 120 are integrally molded. The integrally molded structure improves the strength of the mounting base 100. The material can be polycarbonate or ABS, etc., and the color can be adjusted according to the requirements. The color can be selected as a light-blocking tone such as gray, which can effectively reduce the light passing through. It can prevent ambient light and other unnecessary light from entering the interior, and prevent unnecessary light loss, thereby improving the detection accuracy.

[0041] In an embodiment of this utility model, the detection mechanism further includes a light-transmitting element 500, which is disposed in the connecting cavity 102 and covers the second through hole. The light-transmitting element 500 is used to transmit light.

[0042] Specifically, a light-transmitting element 500 is provided inside the connecting cavity 102. The outer wall of the light-transmitting element 500 is tightly fitted with the inner wall of the second through hole, which can effectively prevent dust, smoke and other fine particles from entering the connecting cavity 102, protect the transmitting component 300 and the receiving component 400 from contamination, and improve their service life. In addition, the light-transmitting element 500 has good light transmission performance and will not attenuate the light signal intensity between the transmitting component 300 and the receiving component 400, thus maintaining detection accuracy while ensuring the sealing effect.

[0043] In one embodiment, the light-transmitting element 500 can be made of polycarbonate or acrylic. Through injection molding, the mold can be customized according to the shape inside the connecting cavity 102, or the connecting plate 120 can be used directly as the mold. That is, the mounting base 100 is made through a one-time injection molding process, and then the mounting base 100 is used as the mold for the second injection molding. Molten plastic is injected into the connecting cavity 102 and left to cool and solidify. At this time, the cooled light-transmitting element 500 fits tightly with the connecting cavity 102. In one embodiment, in order to prevent the light-transmitting element 500 from detaching from the connecting cavity 102, multiple positioning grooves are provided at intervals on the inner wall of the connecting cavity 102 when the mounting base 100 is injection molded. Correspondingly, during the second injection molding, multiple positioning protrusions are provided at intervals on the outer wall of the light-transmitting element 500. The positioning protrusions engage with the positioning grooves, which can further improve the stability of the assembly of the light-transmitting element 500 and the mounting base 100.

[0044] In an embodiment of this utility model, the light-transmitting component 500 is provided with a mounting cavity 510 and a mounting port communicating with the mounting cavity 510. The mounting port faces away from the cylinder 110. The transmitting component 300 and the receiving component 400 are disposed in the mounting cavity 510, and the circuit board 200 is disposed in the mounting port.

[0045] Specifically, the light-transmitting component 500 is located within the connecting cavity 102. On the side of the component away from the cylinder 110, i.e., the side closest to the circuit board 200, there is a mounting cavity 510 and a mounting port communicating with the mounting cavity 510. The circuit board 200 is located at the mounting port. The transmitting component 300 and the receiving component 400 protrude from the circuit board 200. The mounting cavity 510 is used to store the transmitting component 300 and the receiving component 400. The transmitting component 300 emits light within the mounting cavity 510. The light passes through the body of the light-transmitting component 500, achieving efficient use of the compact space.

[0046] In an embodiment of this utility model, the detection mechanism further includes a protective cover 600, which connects the connecting plate 120 and the circuit board 200 to fix the circuit board 200 to the connecting plate 120.

[0047] Please refer to Figure 2 The protective cover 600 is used to connect the circuit board 200 and the connecting plate 120, providing a physical barrier for the circuit board 200. Since the detection mechanism moves frequently with the electronic cigarette, the protective cover 600 can prevent the circuit board 200 from being damaged by accidental collisions or drops. In addition, the protective cover 600 can also reduce the impact of external electromagnetic interference on the receiving component 400, transmitting component 300 and other sensitive components on the circuit board 200, ensuring the stability and reliability of the transmission.

[0048] In one embodiment, the protective cover 600 is made of metal, which has a good electromagnetic shielding effect. It is preferably made of aluminum, copper or stainless steel, etc. It has good thermal conductivity and can effectively conduct heat away from the circuit board 200. The protective cover 600 absorbs heat by directly contacting the circuit board 200 and dissipates the heat, effectively reducing the temperature of the transmitting component 300 and the receiving component 400 and avoiding affecting the detection results.

[0049] In an embodiment of this utility model, the protective cover 600 includes:

[0050] The mounting part 610 is attached to the surface of the circuit board 200 facing away from the cylinder 110;

[0051] The clamping part 620 is provided on opposite sides of the mounting part 610 to clamp and fix the circuit board 200 and the connecting plate 120.

[0052] Please refer to Figure 2 The circuit board 200 is attached to the side of the connecting plate 120 away from the cylinder 110. The protective cover 600 includes a fixing part 630, a mounting part 610, and a clamping part 620. The fixing part 630 is installed on one side of the connecting part, the clamping part 620 is installed at both ends of the fixing part 630, and the mounting part 610 is installed on one side of the fixing part 630 and attached to the side of the circuit board 200 away from the connecting plate 120. The clamping part 620 clamps and fixes the circuit board 200 and the connecting plate 120 together. The mounting part 610 presses the circuit board 200 towards the connecting plate 120, which improves the stability of the connection between the circuit board 200 and the connecting plate 120. The mounting part 610 is in close contact with the circuit board 200, which increases the contact area and improves the heat dissipation effect.

[0053] In an embodiment of this utility model, the connecting plate 120 includes a fixed section 121 and a suspended section 122. The fixed section 121 is connected to the outer peripheral wall of the cylinder 110.

Under the pressure reduction of the clamping part 620, the circuit board 200 is pressed tightly onto the suspended section 122.

[0055] In an embodiment of this utility model, the detection mechanism further includes a positioning structure 700. The positioning structure 700 passes through the circuit board 200 and is fixedly connected to the suspended section 122. In one embodiment, the positioning structure 700 uses screws to fix the circuit board 200 to the suspended section 122. With the clamping of the clamping part 620, the fixing effect is improved, and the clamping force is prevented from weakening under long-term use, causing the circuit board 200 to shift and affecting the detection. In another embodiment, the positioning structure 700 can also use Velcro. The circuit board 200 is attached to one side of the suspended section 122 by Velcro. In order not to affect the installation of components on the circuit board 200 and the use of the transmitting component 300 and the receiving component 400, the Velcro can be set on the edge of the circuit board 200 facing the suspended section 122.
