[0026] Embodiment 1

[0027] This embodiment provides a sliding cover assembly 100 of a heat-not-burn device, please refer to Figures 1-6 The sliding cover assembly 100 includes an upper cover 110, a sliding member 120, and a limiting structure 130.

[0028] Please refer to Figures 1-2 The upper cover 110 has an insertion port 111 for communicating with a heating cavity of the heat-not-burn device. The sliding member 120 is arranged on the upper cover 110 and can slide along the length direction of the upper cover 110 to cover or expose the insertion port 111. The limiting structure 130 includes a limiting member 131 and an elastic member 132. The limiting member 131 is movably arranged on the upper cover 110, and an end of the limiting member 131 away from the upper cover 110 abuts against the sliding member 120. One end of the elastic member 132 abuts against the upper cover 110 or a fixed base body of the heat-not-burn device, and the other end of the elastic member 132 abuts against the limiting member 131. The elastic member 132 has a restoring force to push the limiting member 131 to move away from the upper cover 110 and abut against the sliding member 120.

[0029] The sliding member 120 is slidably arranged on the upper cover 110 to cover or expose the insertion port 111. In addition, the limiting member 131 is movably arranged on the upper cover 110, and an end of the limiting member 131 away from the upper cover 110 abuts against the sliding member 120. One end of the elastic member 132 abuts against the upper cover 110 or a fixed base body of the heat-not-burn device, and the other end of the elastic member 132 abuts against the limiting member 131. The restoring force of the elastic member 132 makes the limiting member 131 abut against the sliding member 120. When the sliding member 120 slides along the length direction of the upper cover 110, the abutting force of the limiting member 131 can make the sliding member 120 more balanced as a whole, and the sliding member 120 will not be unbalanced at different positions due to the existence of the gap between the upper cover 110 and the sliding member 120, and the sliding member 120 will not be tilted up and down during the sliding process, thereby improving the user's use feeling.

[0030] Please refer to Figure 2 and Figure 4The limiting piece 131 has a mounting end 1311 and a limiting end 1313, and the limiting end 1313 is arranged on the mounting end 1311 in a protruding manner along the circumferential side of the mounting end 1311.

[0031] The mounting end 1311 is movably arranged on the upper cover 110, which facilitates the movement of the limiting piece 131 along the upper cover 110 towards the sliding piece 120. The connection between the limiting end 1313 and the mounting end 1311 is arranged in a T-shaped structure, which on one hand facilitates the limitation of the sliding piece 120 on the upper cover 110, and on the other hand facilitates the sliding of the sliding piece 120 relative to the limiting end 1313.

[0032] Please refer to Figures 2-3 The sliding cover assembly 100 further comprises a fixing piece 140, which is used for being fixed in the accommodating cavity of the heat-not-burn device. The mounting end 1311 is movably connected with the fixing piece 140, one end of the elastic piece 132 abuts against the fixing piece 140, and the other end abuts against the limiting piece 131, so that the limiting piece 131 can abut against the sliding piece 120. In this embodiment, the fixing piece 140 can be a part of the sliding cover assembly 100, or even a part of the upper cover 110, or fixedly connected with the upper cover 110, or a fixed base body of the heat-not-burn device. In this embodiment, the elastic piece 132 is a spring.

[0033] The fixing piece 140 is fixed in the accommodating cavity of the heat-not-burn device, or fixedly connected with the upper cover 110, and movably connected with the mounting end 1311, which can be at the position of the upper cover 110 relative to the fixing limiting piece 131, and can provide a force point for the restoring force of the elastic piece 132.

[0034] Please refer to Figure 2 The fixing piece 140 has an insertion end 141, and the mounting end 1311 has an insertion cavity 1312. The insertion end 141 is movably arranged in the insertion cavity 1312, and the axial direction of the insertion cavity 1312 is parallel to the axial direction of the insertion port 111.

[0035] In this embodiment, the limiting piece 131 is movably arranged on the upper cover 110 in a relatively stable manner only through the simple cooperation structure of the insertion cavity 1312 and the insertion end 141. That is, the insertion cavity 1312 and the insertion end 141 both have a certain length, and the insertion end 141 cannot easily come off from the insertion cavity 1312, so that the limiting piece 131 can have a certain stroke in the axial direction of the insertion cavity 1312.

[0036] Please refer to Figures 1-2The sliding piece 120 has a sliding groove 121 and a dust cover 122 sleeved on the sliding groove 121. The mounting end 1311 penetrates the sliding groove 121, and one side of the limiting end 1313 abuts against the sliding groove 121 to limit the sliding groove 121 on the upper cover 110, and the sliding groove 121 can slide relative to the limiting end 1313. The side of the limiting end 1313 away from the sliding groove 121 can abut against the dust cover 122, so that the elastic piece 132 can push the limiting piece 131 to abut against the dust cover 122.

[0037] In the embodiment, the dust cover 122 and the sliding groove 121 have a gap therebetween, and the limiting end 1313 is located in the gap between the dust cover 122 and the sliding groove 121. On the one hand, the limiting end 1313 can abut against the sliding groove 121 and slide along the sliding groove 121, and on the other hand, under the action of the restoring force of the spring, the end of the limiting end 1313 away from the sliding groove 121 can abut against the dust cover 122, so that the entire sliding piece 120 remains relatively stable during the sliding process, and the upper cover 110 and the sliding piece 120 will not be raised up due to the existence of the gap therebetween.

[0038] In the embodiment, the end of the limiting piece 131 towards the dust cover 122 has a planar structure, and in other embodiments, the end of the limiting end 1313 in contact with the dust cover 122 can be provided with an arc surface structure, so as to reduce the contact area between the limiting end 1313 and the dust cover 122, and further reduce the frictional resistance between the limiting piece 131 and the sliding piece 120.

[0039] Please refer to Figure 5 The sliding groove 121 includes a first non-wavy section 1211, a wavy section 1212 and a second non-wavy section 1213 along the length direction of the upper cover 110.

[0040] The first non-wavy section 1211 and the second non-wavy section 1213 facilitate the positioning of the limiting piece 131 in the sliding groove 121, that is, the position of the limiting piece 131 at the two ends of the sliding groove 121 is the normal state, at this time, the limiting piece 131 does not need to apply an abutting force to the dust cover 122. The wavy section 1212 is provided in a convex manner relative to the first non-wavy section 1211 and the second non-wavy section 1213, which can further increase the abutting force of the limiting piece 131 against the dust cover 122 during the sliding process of the sliding groove 121, and further improve the stability of the sliding piece 120 during the sliding.

[0041] Please refer to Figure 6The side of the sliding member 120 facing the upper cover 110 has a support structure 1214 in contact with the upper cover 110.

[0042] The support structure 1214 is provided on the sliding member 120 and protrudes from the sliding member 120, and has a small contact area with the upper cover 110, thereby reducing the friction when the sliding member 120 slides relative to the upper cover 110.

[0043] Embodiment 2

One end of the elastic member 132 abuts against the upper cover 110 or a fixed base body of the heat-not-burn device, and the other end of the elastic member 132 abuts against the limiting member 131. The elastic member 132 has a restoring force to push the limiting member 131 to move away from the upper cover 110 and abut against the sliding member 120.

[0046] The sliding member 120 is slidably arranged on the upper cover 110 to cover or expose the insertion opening 111.

At least part of the sliding piece 120 is located between the limiting end 1313 and the upper cover 110, so as to limit the sliding piece 120 on the upper cover 110.

[0048] The mounting end 1311 is movably arranged on the upper cover 110, which facilitates the movement of the limiting piece 131 along the upper cover 110 towards the sliding piece 120. The connection between the limiting end 1313 and the mounting end 1311 is arranged in a T-shaped structure, which facilitates the limitation of the sliding piece 120 on the upper cover 110 and the sliding of the sliding piece 120 relative to the limiting end 1313.

[0049] In the embodiment, the upper cover 110 further includes a mounting groove. The mounting end 1311 and the elastic piece 132 are located in the mounting groove.
