Description

Technical Field

[0001] The present invention belongs to the technical field of heating smoking devices, and relates to a smoking device with a side-mounted dust cover. Background Art

[0002] Most of the existing devices for heating cigarette sticks are equipped with a sliding or rotating dust cover around the hole where the cigarette stick is inserted. Whether they are externally mounted sliding or rotating (the rotating type is only externally mounted), or internally mounted sliding, the dust cover is inside or outside the same surface around the cigarette stick insertion hole, and its function is single. With the continuous advancement of the miniaturization of heating smoking devices, the area at the cigarette stick insertion end is getting smaller and smaller. Some smoking devices can no longer install or use such sliding or movable covers, and can only adopt other forms or abandon the design of the dust cover.

[0003] In addition, on the other hand, the three main functional components of the dust cover, working status indicator light, and power switch of the cigarette stick heating smoking device are separately and independently arranged in different areas of the smoking device, which increases the operation complexity of the heating smoking device, or increases the risk that when a child accidentally gets the heating smoking device and wrongly inserts a finger and activates the power switch, resulting in scalding.

[0004] The present invention provides a smoking device that integrates a dust cover, a working status indicator light, and a power switch and has a dust cover. Summary of the Invention

[0014] The inner guide groove support 13 for turning can be provided independently or can be integrally simplified with the corresponding part of the housing 1.

[0015] Alternatively, the steering device is a rolling wheel 8, and the rolling wheel 8 is connected to the smoking device through the rotating shaft 9.

[0016] Preferably, the smoking device includes an LED board 3, and the LED board 3 includes: fixing screws 31, LED indicators 32, and flexible flat cables 33;

[0017] The push bar 2 is made of light-tight material, the sliding key 4 is made of light-transmitting material, the LED board 3 is electrically connected to the output end of the working state indication circuit of the main control circuit board of the smoking device through the flexible flat cable 33, and the LED board 3 is fixed on the push bar 2.

[0018] Preferably, the dust cover slide rail 11 includes: a left dust cover slide rail 11L and a right dust cover slide rail 11R, which are respectively located on both sides of the dust cover 21.

[0019] Preferably, the push bar slide rail 14 includes: a left push bar slide rail 14L and a right push bar slide rail 14R. The left push bar slide rail 14L and the right push bar slide rail 14R are respectively located on both sides of the push bar 2 to form the push bar slide rail 14.

[0057] Figure 1 a is a sectional view taken along the width B - B direction of the smoking device, and other components are not shown.

[0058] Figure 1 b is a sectional view taken along the thickness A - A direction of the smoking device, and other components are not shown.

[0059] Figure 1 c is a partial enlarged view of the end of the push bar 2 after removing the LDE lamp board 3 series components of the smoking device.

[0060] Figure 2 is a schematic diagram of the plane expansion of the push bar 2.

[0061] The cigarette to be heated can be inserted into the cigarette heating structure from the cigarette insertion hole 12 above the shell 1.

[0062] The diameter of the cigarette insertion hole 12 is greater than or equal to the diameter of the cigarette.

[0063] The cigarette heating structure is in the cavity 3 inside the shell 1. Figure 1 The specific structures are not shown in a and 1b.

[0064] Under the operation of the smoking device user, the push rod 2 is fixedly connected to the sliding key 4 fixedly connected to the upper end thereof through the connecting hole 23. The connecting hole 23 is a waist-shaped hole.

[0065] At the top end face of the shell 1 where the cigarette insertion hole 12 is located and at the inner corner of the side where the sliding key 4 is located, an inner guide groove support 13 with an inner arc shape formed integrally with the shell is provided. Its function is to allow the push rod 2 to have a slender connecting strip at the corner where the top end face and the side where the sliding key 4 are located, which is convenient for the push rod 2 to turn, and will not cause self-locking and other faults during sliding.

[0066] Push bar 2 Figure 2 As shown, the dust cover 21 thereon is nearly square or circular, and the bottom is a narrow and long thin sheet of flexibility, smooth surface, non-sticky, and synthetic material resistant to a certain high temperature, such as nylon, synthetic resins, plastics, perfluororubber, synthetic fibers, etc. The color of the push strip 2 is preferably dark and opaque, preferably black and completely light-shielding, so as to block the stray light from the direction of the non-insertion column 41 (non-design direction) in the empty space of the switch sliding groove 15 of the housing 1. The sliding key 4 is made of a light-transmitting material, and the insertion column 41 is made of a light-transmitting material to achieve the light transmission of the LDE light panel 3 to indicate the working status of the smoking device. The insertion column 41 acts as a light guide column. The sliding key 4 acts as a light guide switch key.

[0067] In addition, the push strip 2 may also be a rigid spring sheet that can withstand a certain degree of bending.

[0068] The sliding key body and the insertion column 41 thereon can be designed as an integral whole, or a waisted cylindrical body matching the connecting hole 23 can be made of material and then integrated with the sliding key body.

[0069] The insertion column 41 is a waist cylinder for the following purposes: 1. to slide in the switch sliding groove 15; 2. the waist cylinder can also prevent the entire sliding key 4 from rotating in the switch sliding groove 15.

[0070] The length of the sliding key body should be greater than or equal to twice the length of the switch sliding groove 15 minus the length of the insertion column 41, and the width should be greater than the width of the switch sliding groove 15 to prevent dust from entering.

[0071] Figure 3 This is an implementation case when the steering device is the rolling wheel 8. The rolling wheel 8 assists in the steering of the push bar 2 and aids in sliding.

[0072] The operation method of this smoking device is as follows:

[0073] When inserting the cigarette to be heated, push the sliding key 4 on the side of the smoking device housing 1 to move downward in the switch sliding groove. At this time, the push bar 2 fixedly connected thereto is divided into the left and right sides 14L and 14R of the push bar 2 by the push bar slide rails 14 on the side wall of the housing 1, so that the dust cover 21 at the other end of the push bar 2 moves along the dust cover slide rails 11 on both sides thereof to restrict the dust cover 21 to move in the designed direction, and is also divided into the left dust cover slide 21L and the right dust cover slide 21R to perform linear sliding. When the thumb of the hand pushes the sliding key 4 to the extreme position below the switch sliding groove 15 of the smoking device, the edge of the dust cover 21 does not block the cigarette insertion hole 12, and the cigarette insertion hole 12 can be completely opened, so that the cigarette to be heated can be inserted into the heating device in the inner cavity 7 of the smoking device without hindrance for heating;

[0074] At the same time, the trigger end 24 of the push bar 2 provides a switch trigger signal to the main control circuit board of the smoking device, the smoking device starts heating, and at the same time the LED board 3 is powered on and started, and the LED indicator 32 is lit.
