Description

Technical Field

[0001] The present invention belongs to the technical field of heating smoking devices, and particularly relates to a smoking device with a dust-proof cover that is convenient to manufacture and a manufacturing method thereof. Background Art

[0002] Most of the existing devices for heating cigarette sticks are equipped with a sliding or rotating dust-proof cover around the hole where the cigarette stick is inserted. Whether they are externally placed sliding or rotating (the rotating type is only externally placed), or internally placed sliding, the dust-proof 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. For some smoking devices, it is impossible to install or use such a sliding or movable cover, and only other forms can be adopted or the design of the dust-proof cover can be abandoned.

[0003] Moreover, the structural design of the internal sliding rail inside the housing is only limited to the structure in which the housing is divided into left and right halves along the length direction of the cigarette stick. Otherwise, problems such as difficult setting or demolding of the top-mounted sliding rail forming die will be faced due to the too small volume of the smoking device, etc., in die design and processing.

[0004] In order to solve the above problems, the present invention is proposed. Summary of the Invention

[0074] A dust-proof cover switch groove 14 is provided on the side surface of the housing 1 to guide the sliding of the dust-proof cover switch 4;

[0075] The tail end of the push bar 2 is provided with a push bar installation hole 23;

[0076] The dust-proof cover switch 4 includes a mounting post 41;

[0077] The mounting post 41 penetrates through the dust cover switch slot 14, the push bar mounting hole 23 and the push bar mounting slot 36, and a spring retaining ring 7 is installed at the end of the mounting post 41 to limit the dust cover switch 4 within the dust cover switch slot 14 and the push bar mounting slot 36. The mounting post 41 is fixedly connected to the push bar mounting hole 23.

[0078] The support plate bracket 3 further includes a transverse reinforcing rib 39, which is disposed on the surface of the second part of the support plate 30 that does not contact the push bar 2, that is, on the non-working surface of the second part of the support plate 30.

[0079] The assembly method of the smoking device with a dust cover is as follows, including the following steps:

[0080] Install the rolling wheel 5 and the rolling wheel shaft 6 on the rolling wheel rotating shaft hole 38 on the vertical reinforcing rib plate 33;

[0081] Insert the push bar body 22 of the push bar 2 between the support plate 30 and the rolling wheel 5, and tie a slipknot with a silk ribbon at one end of the dust cover 21 of the push bar 2 to the surface of the first part of the support plate 30 close to the cigarette insertion hole 12 inside the housing 1;

[0082] Then install the assembled support plate bracket 3 assembly into the inside of one end of the housing 1 with the cigarette insertion hole 12, so that the rolling wheel 5 is located at the corner between the top surface and the side surface of the housing 1, and the first part of the support plate 30 is arranged along a direction parallel to the top surface of the housing 1, and the second part of the support plate 30 is arranged along a direction parallel to the side surface of the housing 1;

[0083] Respectively use screws to connect the lower fixing seat 34 and the upper fixing seat 31 of the support plate bracket 3 assembly to the middle fixing seat 13 and the top fixing seat 11 of the housing respectively. Untie the silk ribbon slipknot, pull out the silk ribbon, first tighten the screw at the lower fixing seat 34, and finally tighten the screw at the upper fixing seat 31, that is, assemble the support plate bracket 3 and the push bar 2 into the smoking device.

[0084] The specific structure of the present invention is as follows:

[0085] As Figure 1 , in order to facilitate and simplify manufacturing and installation, the support plate bracket 3 is designed and manufactured as an independent part in the present invention. The working surface of the support plate 30 on the support plate bracket 3 that contacts the push bar 2 is a continuous working surface with a 90-degree bend.

[0086] The support plate bracket 3 can be prefabricated into a finished product by using a molding or casting method.

[0087] In order to ensure the strength of this continuous, curved working surface and the correct installation working state, the present invention adds an upper fixed seat 31, a reinforcement plate 32, vertical reinforcement ribs 33, a lower fixed seat 34, and an upper fixed seat reinforcement rib plate 35. Among them, these auxiliary structures are respectively represented by left and right - corresponding to L and R and corresponding part numbers in order to accurately express or indicate the position of the push strip 2 they serve, the push strip installation groove 36, and the support plate cigarette hole 37 for cigarettes to pass through, the rolling wheel shaft hole 38 and the transverse reinforcement rib 39. These main structures constitute the structural parts supporting the push strip 2.

[0088] Among them, a pair of upper fixing seats 31, upper left fixing seat 31L and upper right fixing seat 31R, and a pair of lower fixing seats 34, lower left fixing seat 34L and lower right fixing seat 34R are used to fix the support plate bracket 3 and the shell 1 to the inner upper wall of the shell 1 through short screws 8 and long screws 9. The push bar 2 reciprocates in the space formed by the shell 1 and the support plate 30, which is equal to or slightly larger than the thickness of the push bar 2. Figure 5 The push rod 2 includes a dust cover 21 fixed at one end thereof, which can reciprocate with the push rod 2 below the cigarette insertion hole 12 to open or close the cigarette insertion hole 12 of the smoking device.

[0089] The upper surface M of the support bracket 3 is matched with the upper inner surface of the shell 1, and the upper surfaces N of the lower fixing seat 34 on the left and right sides, the left lower fixing seat 34L and the right lower fixing seat 34R, are matched with the base surfaces on the left and right sides of the shell middle fixing seat 13 protruding inside the shell 1, the left shell middle fixing seat 13L and the right shell middle fixing seat 13R, to fix the main force-bearing surface. The upper fixing seat 31 on the left and right sides, the upper left fixing seat 31L and the upper right fixing seat 31R, are further auxiliary fixed with the top of the shell 1, the thickened shell top on one side of the cigarette insertion hole 12, and the left shell top fixing seat 11 on the left and right sides, to ensure that the dust cover 21 of the smoking device can be opened or closed normally and reliably.

[0090] Due to the miniaturization of the smoking device, the thickness of the support bracket 3 will be very small. Therefore, in order to ensure the reliable movement of the push rod 2, the left and right reinforcing plates 32 of the push rod 2 moving force direction, the left reinforcing plate 32L, the right reinforcing plate 32R, the left vertical reinforcing plate 33L, and the right vertical reinforcing plate 33R are added from different directions and angles without interfering with the normal operation of the cigarette heating device in the smoking device as much as possible.

[0091] An upper fixing seat reinforcement plate 35 with an inclination is added on both sides of the upper fixing seat 31 that auxiliary supports the dust cover 21. The upper fixing seat reinforcement plate 35 includes: a left upper fixing seat reinforcement plate 35L and a right upper fixing seat reinforcement plate 35R.

[0092] The left upper fixing base reinforcing plate 35L and the right upper fixing base reinforcing plate 35R are close to the reverse side of the working surface of the tray support 3 and on both sides close to the side of the housing 1 where the cigarette insertion hole 12 is installed, so as to ensure that after the smoking device heats up and works, the dust cover 21 can still be reliably supported and can be continuously opened and closed.

[0093] Figure 2 It is the three-view drawing of the smoking device in the closed state of the dust cover 21, where a is the sectional view taken along A-A, b is the sectional view taken along B-B, c is the sectional view taken along C-C, and the rest of the smoking device is not shown.

[0094] Figure 2 In it, the mounting post 41 of the dust cover switch 4 is fixedly connected to the corresponding mounting hole 23 on the push bar 2, such as interference fit, gluing connection, thermal bonding, etc. The mounting post 41 is also outside the push bar mounting groove 36 of the tray support 3, and a spring retaining ring 7 is installed to prevent the dust cover switch 4 from falling. Of course, the spring retaining ring 7 can also be replaced with a material of the same or similar material as the mounting post 41 to make further strengthening connection at the end where the mounting post 41 passes through, so as to improve the reliability of the smoking device.

[0095] The process of installing the dust cover switch mechanism of the present invention is as follows:

[0096] First, take the finished product tray support 3, the rolling wheel 5 and the "T"-shaped rolling wheel shaft 6 and Figure 3 at the corner shown in the D-D section view, axially position the rolling wheel 5 on the rolling wheel rotating shaft holes 38 at the corners of the left vertical reinforcing rib plate 33L and the right vertical reinforcing rib plate 33R.

[0097] The present invention uses the "T"-shaped rolling wheel shaft 6 mainly to facilitate fixing at one end. Of course, the present invention can also use a general round shaft, but the hole-shaft tolerance fit relationship with the rolling wheel rotating shaft hole 38 needs to be considered.

[0098] Among them, there is a hole with a larger diameter at one end of the left vertical reinforcing rib plate 33L. This hole is in interference fit with the larger diameter end of the "T"-shaped roller shaft 6, or is bonded with a little special glue at the larger end of the rolling wheel rotating shaft hole 38; so that the roller 5 can rotate freely around the roller shaft 6, and there is no relative rotation between the roller shaft 6 and the rolling wheel rotating shaft hole 38.

[0099] Then insert the narrow end of the push bar 2 between the roller 5 and the tray support 3, tie a slipknot at one end of the dust cover 21 with the large head of the push bar 2 on the reverse side of the working surface of the inclined tray support 3, and the lengths of the two silk ribbons on both sides of the slipknot are greater than the length after being installed in the housing 1, so that the silk ribbon ends are left outside;

[0100] Insert the above-assembled mechanism into one end of the housing 1 with the cigarette insertion hole 12. After the M end face of the pallet support 3 and the outer surface of the push bar 2 are close to the inner surface of the upper part of the housing 1, use the long screw 9 to install the pallet support 3 assembly into the holes on both sides of the housing fixing seat 13 on the inner side of the housing 1, but do not fully tighten it.

[0101] Take the short screw 8 and connect both sides of the upper fixing seat 31 on the pallet support 3 to both sides of the housing top fixing seat 11 near the cigarette insertion hole 12 on one side of the inner top of the housing 1. Before the short screw 8 is fully tightened, untie the ribbon of the fixed dust cover 21 with a slipknot, and carefully pull out the ribbon, and pay attention not to leave any residual silk thread between the housing 1 and the pallet support 3. If there is any residue, use tweezers to carefully remove it. Then first tighten the long screw 9 on the housing fixing seat 13, and then tighten the short screw 8 on the housing top fixing seat 11.

[0102] On one side of the dust cover switch hole 14 on the side of the housing 1, find the mounting hole 23 on the push bar 2, install the dust cover switch mounting post 41 on the dust cover switch 4 into the mounting hole 23. Finally, the dust cover switch mounting post 41 extends to the push bar mounting groove 36, and install the spring clip 7 on the mounting post 41 so that the spring clip 7 slides outside the push bar mounting groove 36.
