The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

In order to describe the technical features, objectives and effects of the present invention more clearly, the specific implementations of the present invention are described in detail below with reference to the accompanying drawings.

As shown in <FIG> and <FIG>, a baked smoking device in a preferred embodiment of the present invention includes a body <NUM>, a heating assembly <NUM>, a sliding button <NUM>, a power source <NUM> and a control board <NUM>.

The body <NUM> includes a casing. The body <NUM> is provided with an accommodating cavity <NUM>, and the heating assembly <NUM> is inserted in the accommodating cavity <NUM>. The heating assembly <NUM> is provided with an insertion hole <NUM> for inserting a cigarette <NUM>.

The sliding button <NUM> is mounted on the body <NUM> and mounted to the heating assembly <NUM>. The sliding button <NUM> is cooperated with the heating assembly <NUM>, and configured to slide along a first stroke to push the cigarette <NUM> in the heating assembly <NUM> out of the insertion hole <NUM> and to slide along a second stroke to push the heating assembly <NUM> out of the accommodating cavity <NUM>.

The sliding button <NUM> is slided to different positions, to push out the cigarette <NUM> and the heating assembly <NUM> respectively. Therefore, the cigarette <NUM> can be conveniently replaced, and the disassembly of the heating assembly <NUM> and a power supply assembly such as the power source <NUM> of the body <NUM> can be conveniently implemented, which facilitates the replacement of the heating assembly <NUM> and clean of the interior of the heating assembly <NUM>.

A side wall of the body <NUM> is provided with a mounting hole <NUM> for the sliding button <NUM> to slide back and forth. The sliding button <NUM> includes an inner sliding member <NUM> and an outer sliding member <NUM> respectively located on inner and outer sides of the side wall of the body <NUM>. The outer sliding member <NUM> extends through the mounting hole <NUM> to be clamped and fixed with the inner sliding member <NUM>. A sliding rail <NUM> for the sliding button <NUM> to slide is provided inside the body <NUM>. In other embodiments, the sliding button <NUM> may alternatively be an integrated structure that is able to slide on the body <NUM>.

As shown in <FIG>, in some embodiments, the heating assembly <NUM> includes a sleeve <NUM>, a push tube <NUM>, a reposition member <NUM>, a heating element <NUM>, a protective cover <NUM>, a clamping seat <NUM>, a heat insulation seat <NUM>, a support assembly <NUM> and a lock sleeve <NUM>.

An inner hole of the push tube <NUM> is defined as the insertion hole <NUM> for inserting the cigarette <NUM>. The sleeve <NUM> is sleeved outside the push tube <NUM>. The sliding button <NUM> abuts against the push tube <NUM>, and the sliding button <NUM> is able to drive the push tube <NUM> and the cigarette <NUM> to move together in the first stroke from a first position A adjacent to an inner end of the insertion hole <NUM> to a second position B adjacent to an outer end of the insertion hole <NUM>.

The reposition member <NUM> is provided between the sleeve <NUM> and push tube <NUM> to provide a force for resetting the push tube <NUM> to the first position A. Preferably, the reposition member <NUM> is a spring sleeved outside the push tube <NUM>, and two ends of the spring respectively abut against the sleeve <NUM> and the push tube <NUM>. The reposition member <NUM> can provide a force to the push tube <NUM> towards an inner end of the accommodating cavity <NUM>. When the cigarette <NUM> is pushed out, and the sliding button <NUM> is released, the push tube <NUM> will move to the first position A automatically. In other embodiments, the push tube <NUM> may alternatively be pushed to the first position A manually.

In order to facilitate the control of the stroke range, the sleeve <NUM> is provided with a first limiting portion <NUM> for limiting the push tube <NUM> when the push tube <NUM> moves to the second position B. When the sliding button <NUM> continues to move to a third position C adjacent to the outside of the accommodating cavity <NUM>, the first limiting portion <NUM> is able to drive the heating assembly <NUM> to move simultaneously towards the outside of the accommodating cavity <NUM> to complete the second stroke of the heating assembly <NUM>.

Preferably, the first stroke and the second stroke are two continuous strokes. If only the cigarette <NUM> needs to be pushed out, the push tube <NUM> moves to the second position B. If the heating assembly <NUM> needs to be pushed out, the push tube <NUM> is continuously pushed outward from the second position B to the third position C, so that the heating assembly <NUM> moves towards the outside of the accommodating cavity <NUM>. In this way, the heating assembly <NUM> can be removed for maintenance.

In some embodiments, the push tube <NUM> is provided with an abutting portion <NUM> that extends laterally outwards, and a side wall of the sleeve <NUM> is axially provided with a sliding groove <NUM>. The abutting portion <NUM> is clamped into the sliding groove <NUM>, and the abutting portion <NUM> is able to move in the sliding groove <NUM>. The sliding button <NUM> abuts against the abutting portion <NUM>, and applies a force to the abutting portion <NUM> to drive the push tube <NUM> to move towards the outside of the accommodating cavity <NUM>. The sliding button <NUM> may alternatively abut against a structure such as a positioning hole on an end or a side wall of the push tube <NUM>, to force the push tube <NUM> to move outward.

Preferably, a side of the sliding groove <NUM> adjacent to the outside of the accommodating cavity <NUM> defines the first limiting portion <NUM>. In other embodiments, the first limiting portion <NUM> may alternatively be separately provided on the sleeve <NUM>.

Further, a second limiting portion <NUM> is provided on the body <NUM> for limiting the sliding button <NUM> when the sliding button <NUM> drives the heating assembly <NUM> to move towards the outside of the accommodating cavity <NUM> to the third position C. A distance between the second position B and the third position C is not limited, as long as the heating assembly <NUM> is pushed outward for a certain distance so that a user can pull the heating assembly <NUM> out of the accommodating cavity <NUM>. Of course, the sliding button <NUM> may alternatively rely on the mounting hole <NUM> to limit a moving range thereof. When the sliding button <NUM> moves to a boundary of a side of the mounting hole <NUM>, the heating assembly <NUM> is just moved to the third position C.

The heating element <NUM> is disposed on the heat insulation seat <NUM>. The heating element <NUM> extends from the bottom of the insertion hole <NUM> to an outer end opening of the insertion hole <NUM>. The protective cover <NUM> is detachably sleeved on the heating element <NUM>. When the heating assembly <NUM> is removed from the accommodating cavity <NUM>, the protective cover <NUM> can be removed for replacement or cleaning.

A thermal conductivity of the heat insulation seat <NUM> is lower than that of the heating element <NUM>, which can prevent the heat on the heating element <NUM> from being transferred to the support assembly <NUM>, a circuit board and a guide, etc., so as to reduce the safety risk.

An end of the protective cover <NUM> towards an outer end of the insertion hole <NUM> is a closed pointed structure. When the cigarette <NUM> is inserted into the insertion hole <NUM>, the closed pointed structure facilitates the insertion of the protective cover <NUM> into the cigarette <NUM>, and also prevents chemicals generated when the cigarette <NUM> is heated from entering the protective cover <NUM>.

Generally, the heating element <NUM> has a cylindrical or sheet shape. An inner surface of the protective cover <NUM> may be closely fit with or spaced apart from the heating element <NUM>, as long as the heat can be transferred to the protective cover <NUM> to heat the cigarette <NUM>.

As shown in <FIG> and <FIG>, in some embodiments, the support assembly <NUM> includes a first clamping member <NUM>, a second clamping member <NUM> and a support sleeve <NUM>. The first clamping member <NUM> and the second clamping member <NUM> clamp the heat insulation seat <NUM>. Two sides of the first clamping member <NUM> and the second clamping member <NUM> towards each other are respectively provided with a positioning groove <NUM> for engaging the heat insulation seat <NUM>, to facilitate positioning.

The heating element <NUM> extends outward into the insertion hole <NUM> from the heat insulation seat <NUM>. Preferably, an abutting wall <NUM> is provided at the bottom of the insertion hole <NUM>. The abutting wall <NUM> is able to abut and position an inner end of the cigarette <NUM>, and the abutting wall <NUM> is provided with a through hole <NUM> for the heating element <NUM> to extend through. The abutting wall <NUM> and the push tube <NUM> are of an integrated structure, or alternatively be two separate components that are relatively fixed in position.

The support sleeve <NUM> is sleeved outside the first clamping member <NUM> and the second clamping member <NUM>. A positioning ring <NUM> is provided on an inner periphery of one end of the support sleeve <NUM> adjacent to the insertion hole <NUM>, for abutting the first clamping member <NUM> and the second clamping member <NUM> to limit axial positions thereof. In other embodiments, the positioning ring <NUM> may alternatively be located on an inner periphery of one end of the support sleeve <NUM> away from the insertion hole <NUM>.

Preferably, one end of the sliding groove <NUM> away from the accommodating cavity <NUM> extends to an end of the sleeve <NUM>. The support assembly <NUM> is mounted into the sleeve <NUM> via an end of the sleeve <NUM> where the sliding groove <NUM> is located. Meanwhile, the abutting portion <NUM> is mounted into the sliding groove <NUM> via an open end of the sliding groove <NUM>. The lock sleeve <NUM> is connected with the end of the sleeve <NUM> where the sliding groove <NUM> is located, to lock the support assembly <NUM> in the sleeve <NUM>.

Preferably, the clamping seat <NUM> is located on a side of the through hole <NUM> opposite to the insertion hole <NUM>, and the clamping seat <NUM> is configured to be clamped and fixed with the protective cover <NUM>. In some embodiments, the clamping seat <NUM> is annular and is sleeved on the heating element <NUM>.

As shown in <FIG>, an inner clamping groove <NUM> is provided on a side wall of an inner periphery of the clamping seat <NUM>, and an outer periphery of an inner end of the protective cover <NUM> is provided with a retaining ring <NUM> that is clamped with the inner clamping groove <NUM>. Further, an outer periphery of the clamping seat <NUM> is provided with an outer clamping groove <NUM> that is clamped with the positioning ring <NUM> of the support sleeve <NUM>. In this way, both the inner and outer peripheries of the clamping seat <NUM> are positioned and fixed. In other embodiments, the protective cover <NUM> may be clamped with only the inner or outer periphery of the clamping seat <NUM>.

Preferably, the clamping seat <NUM> is made of a soft material, which is convenient for the protective cover <NUM> to squeeze the clamping seat <NUM> and snap into the inner clamping groove <NUM>, and is also convenient for the clamping seat <NUM> to be disassembled. When the protective cover <NUM> is removed, the clamping seat <NUM> may also be removed simultaneously for cleaning.

An outer size of the through hole <NUM> is smaller than a size of the inner periphery of the clamping seat <NUM>, which facilitates the abutment of the clamping seat <NUM> and prevents the protective cover <NUM> from being pulled out of the through hole <NUM>.

Preferably, an outer periphery of the retaining ring <NUM> is provided with a surrounding plate <NUM> extending in a direction of the outer end opening of the insertion hole <NUM>. The surrounding plate <NUM> and the retaining ring <NUM> form a container outside the protective cover <NUM>, which is used to contain an impurity falling from the protective cover <NUM> during use, so as to prevent contamination of other components. Preferably, a gap is defined between an inner periphery of the through hole <NUM> and an outer wall surface of the protective cover <NUM>, so that the impurity on the protective cover <NUM> is able to fall from between the through hole <NUM> and the protective cover <NUM> to the container formed by the surrounding plate <NUM> and the retaining ring <NUM>.

Further, as shown in <FIG>, <FIG>, and <FIG>, the body <NUM> is provided with a locking structure <NUM> for positioning and fixing the inserted heating assembly <NUM>. As the heating assembly <NUM> is fixed in position, it will not shake and loosen during use.

In some embodiments, the locking structure <NUM> includes a lock head <NUM>. The lock head <NUM> retractably extends from a side wall surface of the accommodating cavity <NUM> into the accommodating cavity <NUM>. An outer wall surface of heating assembly <NUM> is provided with a lock groove <NUM> for the lock head <NUM> to be snapped into. When the lock head <NUM> is snapped into the lock groove <NUM>, the heating assembly <NUM> is prevented from leaving the accommodating cavity <NUM>.

Preferably, an end of the lock head <NUM> towards the accommodating cavity <NUM> is tapered or round, and a side wall surface of the lock groove <NUM> is an inclined surface or an arc surface, enabling the heating assembly <NUM> to overcome a locking force of the lock head <NUM> under the push by the sliding button <NUM> to let the lock head <NUM> be retracted, so that the heating assembly <NUM> is removed from the accommodating cavity <NUM>. In other embodiments, when the heating assembly <NUM> needs to be removed from the accommodating cavity <NUM>, the lock head <NUM> may alternatively be retracted manually, so that the lock of the lock head <NUM> is released.

Generally, the locking structure <NUM> further includes an elastic member <NUM> that provides an elastic force to keep the lock head <NUM> extending into the accommodating cavity <NUM>. The elastic member <NUM> is a spring. Further, in this embodiment, the lock groove <NUM> is circumferentially provided on an outer surface of the sleeve <NUM>, so that a circumferential position of the heating assembly <NUM> when mounting into the accommodating cavity <NUM> can be neglected.

Understandably, the above technical features can be arbitrarily combined without limitation as long as the resulting embodiment is encompassed by the scope of the appended claims.
