Description

Heating device with automatic cigarette removal structure and use method

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on June 26, 2023, with application number 202310765778.0 and invention name “A heating device with an automatic cigarette removal structure and its use method”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The invention belongs to the field of novel tobacco equipment and relates to a heating device with an automatic cigarette taking structure and a use method thereof. Background Art

[0003] Since the invention of cigarette-making machines in the late 19th century, modern cigarettes have become the primary form of tobacco consumption, with a history of over a century. Modern cigarettes use paper to wrap tobacco, which, when lit, releases its flavor and is then smoked for a satisfying sensation.

[0004] With the increasingly stringent tobacco control policies and the increasing pressure of consumers' health awareness, it is becoming increasingly difficult to make breakthroughs in modern cigarettes. As an electronic product to replace cigarettes, the new type of heat-not-burn cigarettes heats the tobacco material inside but does not burn it. It has a similar appearance, smoke, taste and feel to cigarettes, but compared with cigarettes, it does not contain the 7,000 harmful chemical components in cigarette smoke. Therefore, it is favored by more and more people.

[0005] However, most of the heating devices used in conjunction with the new heat-not-burn cigarettes currently adopt an inner core heating method. A central heating element is built into the heating device. When in use, the cigarette is inserted into the smoking device, and the heating element extends into the smoking section of the cigarette and contacts the smoking substance. The heating element heats and bakes the cigarette for the user to inhale. After the inhalation is completed, the heating element will adhere to the smoking substance. Therefore, when the cigarette is taken out, the smoking substance often falls into the heating chamber and accumulates in the heating chamber, which is difficult to clean, causing a lot of trouble for the repeated use of the heating device.

[0006] Summary of the Invention

[0007] In order to address the existing problem of heat-not-burn cigarettes easily sticking to the heating element when removed after puffing, causing the smoky substance to fall out, the present invention incorporates an automatic cigarette removal mechanism into the heating device. This automatically and quickly removes the heat-not-burn cigarette from the heating element after puffing, preventing the smoky substance from falling out.

[0008] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0013] The movable plate is supported by the elastic member and moves away from the bottom of the heating device main body to form a first state; the movable plate overcomes the elastic force of the elastic member, causing the elastic member to be compressed and moves closer to the bottom of the heating device main body to form a second state;

[0014] The bottom of the heating device main body is further provided with a locking device so that the movable plate is maintained in the second state.

[0015] Preferably, the locking device is a slide groove limiting structure.

[0016] Preferably, the slide groove limiting structure is specifically as follows: at least one slide groove is provided on the outer surface of the heating device body, and a protrusion is provided on the movable plate, and the protrusion moves axially in the slide groove along with the movable plate; at the same time, the slide groove is provided with a limiting groove in the radial direction near the bottom of the heating device body tube, and the protrusion can be rotated to the limiting groove for locking in the second state.

[0022] Preferably, the outer surface of the heating device body is further provided with buttons and a display screen.

[0023] A method for using a heating device with an automatic cigarette removal structure comprises the following steps:

[0024] (1) The consumer brings the front end of the heat-not-burn cigarette into contact with the movable plate in the first state.

Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in this application without affecting the efficacy and purpose that can be achieved by this application.

[0034] The technical solution of the present invention is further described in detail below.

[0035] The technical problem to be solved by the present invention is that after smoking a new type of heat-not-burn cigarette, the cigarette part is easily adhered to the heating element when it is taken out from the heating device, causing the smoking substance to fall into the heating device.

[0036] The present invention improves the existing heating device and provides a structure with automatic cigarette removal, including:

[0037] The heating device body 1 is similar to the heating device bodies in the prior art and is also closed at the bottom. It has a hollow structure and a cylindrical design of a circular heating chamber corresponding to the cigarette structure of the new heat-not-burn cigarette, so that the cigarette structure can be smoothly inserted into the heating device body 1;

[0038] The heating element 2 is fixedly connected to the center of the bottom of the heating device body 1 by means including but not limited to welding or bolting, so that after the cigarette structure is inserted into the heating chamber 11, the heating element 2 can be easily connected to the smoking material in the cigarette structure. The bottom of the heating device body 1 is also connected to a power supply 12 and a circuit control board 13. The power supply 12 and the circuit control board 13 are both electrically connected to the heating element 2 to provide energy to the heating element 2 and control its on / off state and heating temperature.

[0039] The sliding portion 3 is also provided in the heating chamber 11 and serves as the main component of the automatic cigarette dispensing structure. The sliding portion 3 includes: a movable plate 31, the area of ​​the movable plate 31 being smaller than the area of ​​the cylindrical inner wall of the heating device body 1. In the present application, the heating device body 1 and the movable plate 31 are both circular, so the diameter of the movable plate 31 is slightly smaller than the inner diameter of the heating device body 1; an elastic member 32, the two ends of the elastic member 32 respectively connecting the movable plate 31 and the bottom of the heating device body 1. In the present application, the elastic member 32 is a spring, and the two ends are respectively connected to the movable plate 31 and the bottom of the heating device body 1 by a hook and loop, which facilitates the removal and replacement of the spring after it is damaged;

[0040] Therefore, the movable plate 31, supported by the elastic member 32, is moved away from the bottom of the heating device body 1 to form a first state, at which time the elastic force provided by the elastic member 32 is equal to the weight of the movable plate 31 itself. When the consumer overcomes the elastic force of the elastic member 32, the movable plate 31 contacts the cigarette structure and presses downward, causing the elastic member 32 to compress and move closer to the bottom of the heating device body to form a second state.

[0041] The bottom of the heating device body 1 is further provided with a locking device 4 so that the movable plate 31 can be maintained in the second state and the elastic force of the elastic member 32 after compression can be overcome without the need for a push force provided by the consumer.

[0042] Example 1

[0043] In a specific embodiment, the locking device 4 is a slide groove limiting structure (not shown). Furthermore, the slide groove limiting structure is specifically as follows: at least one slide groove is provided on the outer surface of the heating device body 1, and a protrusion is extended on the movable plate 31. The protrusion moves axially along the heating device body 1 in the slide groove along with the movable plate 31; at the same time, the slide groove is provided with a limiting groove in the radial direction near the bottom of the heating device body 1. In the second state, the protrusion can rotate circumferentially to rotate the protrusion into the limiting groove. At this time, the protrusion is locked by the limiting groove in the axial direction of the heating device body 1 to achieve the purpose of locking, so that the movable plate 31 is maintained in the second state.

[0044] Example 2

[0045] In another specific embodiment, as shown in FIG. 1 and FIG. 2 , the locking device 4 is an electromagnetic locking structure.

[0046] Furthermore, the electromagnetic locking structure is specifically as follows: electromagnets 41 are evenly distributed on the circumference of the bottom of the heating device body 1, and the electromagnets 41 are electrically connected to the power supply 12 and the circuit control board 13 to provide energy to the electromagnet 41 and control its switching state and magnetic field size. A permanent magnet 42 is correspondingly provided at the bottom of the movable plate 31. In this embodiment, the material of the permanent magnet 42 includes but is not limited to neodymium iron boron permanent magnets. The electromagnet 41 is energized in the second state to generate magnetic force, and is adsorbed and locked with the permanent magnet 42 provided at the bottom of the movable plate 31. At this time, the adsorption force generated by the electromagnet 41 plus the gravity of the movable plate 31 itself just offsets the elastic force generated by the spring of the elastic member 32.

[0047] Furthermore, in order to automatically control the opening state of the electromagnet 41, as shown in Figures 1 and 2, a sensor component 5 is further provided on the inner wall of the heating device body 1 away from the bottom of the tube. The sensor component 5 includes but is not limited to a Hall element, a photoelectric sensor, etc.; the main purpose of the sensor component 5 is to detect the activity state of the movable plate 31. When the consumer presses down the movable plate 31 with the cigarette structure against the movable plate 31, the sensor component 5 detects that the movable plate 31 is released from the first state, and the state information is transmitted to the circuit control board 13 in the form of an electrical signal to control whether the electromagnet 41 is turned on or not.

[0048] Preferably, since in the present application, the movable plate 31 needs to move axially within the heating device body 1 from time to time, it is necessary to avoid the fixed heating element 2 to prevent the heating element 2 from interfering with the movable plate 31. Therefore, the present application provides a through hole 33 in the middle of the movable plate 31, and the diameter of the through hole 33 is larger than the diameter of the outer surface of the heating element 2. Therefore, when the movable plate 31 switches between the first state and the second state, the heating element 2 will not interfere with it in a limiting manner.

[0049] Furthermore, since the movable plate 31 is in contact with the cigarette structure and is close to the heating element 2, the material of the movable plate 31 is selected to be a high-temperature resistant material to ensure that it will not be deformed due to temperature during use.

[0050] Preferably, the outer surface of the heating device body 1 is also provided with buttons and a display screen, which are electrically connected to the power supply 12 and the circuit control board 13, and are used to switch the state of the movable plate 31 and control the temperature of the heating element 2 to meet the needs of consumers in more usage scenarios. As shown in Figure 3, another aspect of the present application also involves a method for using a heating device containing the automatic cigarette dispensing structure of the present application, including the following steps:

[0051] (1) The consumer brings the front end of the heat-not-burn cigarette into contact with the movable plate 31 in the first state. At this time, under the external force of the consumer, the heat-not-burn cigarette and the movable plate 31 are pushed toward the bottom of the heating device body 1, overcoming the elastic force of the elastic member 32 and moving until the movable plate 31 reaches the second state. At this time, the locking device 4 maintains the movable plate 31 in the second state, the elastic member 32 is in a compressed state, and the heating element 2 is inserted into the heat-not-burn cigarette and contacts the smoking substance.

[0052] (2) After the consumer has finished smoking, the locking device 4 releases the second state of the movable plate 31. At this time, under the elastic force of the elastic member 32, the movable plate 31 and the heat-not-burn cigarette are driven to move away from the bottom of the heating device body 1. During this process, the heating element 2 is also separated from the heat-not-burn cigarette until the movable plate 31 returns to the first state. At this time, the heat-not-burn cigarette can be easily taken out.

[0053] The above description is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the creative concept of the present invention, but these improvements all fall within the scope of protection of the present invention.
