Cigarette insertion self-start heating structure

Abstract

This invention discloses a self-starting heating structure for cigarette insertion, comprising: a capacitive pressure sensor installed on the outer wall of the cigarette cup to sense the pressure exerted on the cup by the insertion of the cigarette; a switching unit disposed on the side of the capacitive pressure sensor away from the cigarette cup; and a drive operation button slidably disposed within the side wall of the switching unit near the capacitive pressure sensor. The drive operation button, through the interaction between the sensor contacts of the capacitive pressure sensor and the drive operation button, enables the switching unit to be turned on or off, thereby starting or stopping the cigarette heating. This structure significantly improves the stability of self-starting heating upon cigarette insertion. It also provides excellent sealing for the triggering system, allowing for reliable operation in various harsh and high-temperature environments.

Description

Technical Field

[0001] This invention relates to the field of low-temperature non-combustible electronic cigarette technology, and more specifically to a self-starting heating structure for inserting a cigarette stick. Background Technology

[0002] In existing technologies, some cigarette insertion self-starting technologies trigger a mechanical switch upon insertion into the cigarette holder, thereby activating the heating function. This type of technology has drawbacks. For the cigarette to trigger the mechanical switch within the holder, the holder must be open or semi-open (i.e., there must be moving parts inside the holder). This ensures the switch is triggered within the holder during cigarette insertion and removal. However, this type of switch structure leads to poor sealing, allowing oil or water vapor to accumulate inside. This can cause the moving parts to malfunction, resulting in the failure of the self-starting heating function. Summary of the Invention

[0003] The purpose of this invention is to provide a self-starting heating structure for cigarette insertion, in order to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A self-starting heating structure for inserting a cigarette includes:

[0006] A capacitive pressure sensor is installed on the outer wall of the cigarette cup to sense the pressure exerted on the cigarette cup by the insertion of the cigarette stick into the cup.

[0007] A switching unit is disposed on the side of the capacitive pressure sensor away from the cigarette cup;

[0008] The drive operation button is slidably disposed in the side wall of the switching unit near the capacitive pressure sensor. The switching unit is turned on or off by the cooperation between the sensor contacts of the capacitive pressure sensor and the drive operation button, thereby starting or stopping the heating of the smoke appliance.

[0009] In some embodiments, the switching unit includes a housing, a spring plate, and a movable spring plate. The housing has a mounting cavity, and the top of the housing has contact plate A and contact plate B. The right side wall of the housing has contact plate C. The drive operation button is slidably disposed on the left side wall of the housing and opposite to the sensor contact of the capacitive pressure sensor. The spring plate is disposed on contact plate C, and the movable spring plate is rotatably disposed on the side wall below contact plate C. The top of the movable spring plate is fixed to contact plate C, and the bottom of the movable spring plate abuts against the end of the drive operation button. When no cigarette is inserted, the spring plate contacts contact plate A, so that the heating circuit of the cigarette device is in a normally open state. When a cigarette is inserted, the spring plate contacts contact plate B under the action of the movable spring plate, so that the heating circuit of the cigarette device is in a normally open state.

[0010] In some embodiments, the spring sheet includes a transition piece and a spring. The transition piece is hammer-shaped and includes a hammer head and a hammer rod disposed on the hammer head. The hammer rod is rotatably connected to a contact piece C. The hammer head is disposed between contact pieces A and B. The spring is sleeved and fixed on the hammer rod and compressed between the top of the housing and the contact piece C.

[0011] In some embodiments, the contact piece C slides left and right on the right side wall of the housing, and protrusions are provided on the contact pieces C on both sides of the right side wall.

[0012] The beneficial effects of the self-starting heating structure for cigarette insertion provided in this application include, but are not limited to:

[0013] This invention features a novel structure and strong practicality. The technical solution employed in this application utilizes a physical contact method. When a cigarette is inserted, it presses against the inner wall of the cigarette cup, triggering a switch via a capacitive pressure sensor mounted on the outer wall of the cup. The sensor then transmits a signal to activate the function. Compared to similar mechanically triggered switches, this design offers better sealing, effectively preventing switch malfunctions caused by oil or water vapor accumulation. It also improves product quality and lifespan. Attached Figure Description

[0024] The following will combine Figure 1-4 This application provides a detailed description of a self-starting heating structure for cigarette insertion, as described in the embodiments of this application. It is worth noting that the following embodiments are merely illustrative of this application and do not constitute a limitation thereof.

[0025] like Figures 1-4As shown, a self-starting heating structure for cigarette insertion includes: a capacitive pressure sensor 4, which is installed on the outer wall of the cigarette cup 3 to sense the pressure exerted on the cigarette cup 3 by the insertion of the cigarette 1; a switching unit, which is located on the side of the capacitive pressure sensor 4 away from the cigarette cup 3; and a drive operation button 5, which is slidably disposed in the side wall of the switching unit near the capacitive pressure sensor 4. The switch unit is turned on or off by the cooperation between the sensor contacts of the capacitive pressure sensor 4 and the drive operation button 5, thereby starting or stopping the heating of the cigarette device 2.

[0026] The switching unit includes a housing, a spring plate 7, and a movable spring plate 10. The housing has an installation cavity, and the top of the housing has a contact plate A9 and a contact plate B6. The right side wall of the housing has a contact plate C8. The drive operation button 5 is slidably disposed on the left side wall of the housing and is opposite to the sensor contact of the capacitive pressure sensor 4. The spring plate 7 is disposed on the contact plate C8, and the movable spring plate 10 is rotatably disposed on the side wall below the contact plate C8. The top of the movable spring plate 10 is fixed to the contact plate C8, and the bottom of the movable spring plate 10 abuts against the end of the drive operation button 5.

[0027] The spring plate 7 includes an adapter plate and a spring. The adapter plate is hammer-shaped and includes a hammer head and a hammer rod disposed on the hammer head. The hammer rod is rotatably connected to the contact plate C8. The hammer head is disposed between the contact plate A9 and the contact plate B6. The spring is sleeved and fixed on the hammer rod and is compressed between the top of the housing and the contact plate C8.

[0028] When cigarette 1 is not inserted, spring plate 7 contacts contact plate A9, so that the heating circuit of cigarette device 2 is in the normally open state; the lower part of moving spring plate 10 is in a slightly compressed state, pushing the drive operation button 5 against the side wall, and then the top of moving spring plate 10 is fixed on contact plate C8. At this time, under the action of moving spring plate 10, contact plate C8 is driven to the right, and contact plate C8 can move slightly left and right in the housing. In order to prevent contact plate C8 from moving out of the housing, a protrusion is provided at the preset position of contact plate C8 to limit the left and right movement of contact plate C8. At this time, combined with the spring, the conical part of spring plate 7 is pressed against contact plate A9.

[0029] When cigarette stick 1 is inserted, the inner wall of the cigarette cup 3 is squeezed, which triggers the capacitive pressure sensor 4 installed on the outer wall of the cigarette cup 3. The sensor contact of the capacitive pressure sensor 4 moves to the right and pushes the drive operation button 5. The drive operation button 5 squeezes the movable spring piece 10 to the right. Through the lever principle, the top of the movable spring piece 10 moves to the left, causing the contact piece C8 to move slightly to the left. At this time, combined with the spring, the conical part of the spring piece 7 is pressed against the contact piece B6.

[0030] The ends of contact piece A9, contact piece B6 and contact piece C8 are respectively connected to the main board of the smoking device 2. When contact piece A9 and contact piece C8 are connected, the smoking device 2 does not heat up, and when contact piece B6 and contact piece C8 are connected, the smoking device 2 heats up.

[0031] When cigarette 1 is pulled out, the sensor contact of capacitive pressure sensor 4 moves to the left, driving the operating button 5 to reset under the elastic force of the lower part of the moving spring plate 10. The spring plate 7C moves to the right under the action of the upper part of the moving spring plate 10. At this time, the spring engages, pressing the conical part of the spring plate 7 against the contact plate A9. Contact plate A9 and contact plate C8 are now connected.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
