Further, a bracket and a cavity are also arranged in the shell, one end of the bracket is fixedly connected with the shell, the other end of the bracket penetrates through the atomization upper cover and is opposite to the atomization surface of the atomization sheet, and a gap for communicating the oil guide piece with the cavity is formed between the outer wall of the bracket and the inner wall of the atomization upper cover; the air outlet channel of the atomizer is arranged in the bracket.

By means of the structure, when the inclined smoke pump or the atomizer is obliquely placed, tobacco tar on the atomizing sheet can enter the cavity in the shell through the gap between the outer wall of the support and the inner wall of the atomizing upper cover, so that the problem that the atomizing sheet is temporarily soaked in the tobacco tar to start slowly or the smoke output is small is solved, and meanwhile, the phenomenon that excessive tobacco tar on the atomizing sheet flows out to the oral cavity through the air outlet channel in the support to scald the oral cavity of a user can be avoided.

In the initial state, the unlocking mechanism locks the connection relationship between the lock ring 24 and the limiting ring 15, at this time, the rotating assembly 13 cannot rotate, and the oil filling hole 402 cannot be opened. When the oil filling hole 402 needs to be opened to fill the oil in the oil bin 5, the connection relationship between the lock ring 24 and the limiting ring 15 is unlocked through the unlocking mechanism, the extension portion 1501 is placed in the rotating cavity 24011, and the rotating assembly 13 can rotate around the extension portion 1501 and open the oil filling hole 402.

The unlocking mechanism comprises a first limit surface 15011 arranged on the outer wall of the extension portion 1501, and a second limit surface 24012 arranged on the inner wall of the accommodating cavity 2401 and matched with the first limit surface 15011. When the oil filling hole 402 needs to be opened to fill oil into the oil bin 5, the rotating assembly 13 is slid firstly, so that the first limiting surface 15011 and the second limiting surface 24012 are unlocked in a staggered manner, the extending portion 1501 enters the rotating cavity 24011, the rotating assembly 13 is rotated at the moment, the rotating assembly 13 rotates around the extending portion 1501 and opens the oil filling hole 402, and oil can be filled into the oil bin 5 at the moment. After the oiling is completed, the rotary assembly 13 is rotated to close the oil filling hole 402, and then the rotary assembly 13 is slid to be aligned and locked with the first limiting surface 15011 and the second limiting surface 24012, so that the whole oiling process can be completed, and the oiling operation is simple and convenient.

In the smoking state or the non-oiling state, the first stop surface 15011 and the second stop surface 24012 are aligned and locked, and the lock ring 24 is locked and fixed. Since the unlocking requires two separate steps, it is possible to prevent the oil leakage phenomenon from occurring when the oil filling hole 402 is arbitrarily opened by a child or when the oil filling hole 402 is opened by a malfunction.

As shown in fig. 6, two rotating cavities 24011 are symmetrically arranged in the accommodating cavity 2401, two intersecting places of the two rotating cavities 24011 are respectively provided with a second limiting surface 24012, namely second limiting surfaces 24012 are symmetrically arranged at the intersecting places, and the distance between the second limiting surfaces 24012 is smaller than the diameter of the rotating cavity 24011, so when the sliding rotating assembly 13 makes the extending part 1501 enter the rotating cavity 24011 to rotate, namely, the rotating assembly 13 and the housing 4 form an included angle of 1-179 degrees or 181-359 degrees, the sliding of the rotating assembly 13 is limited by the two second limiting surfaces 24012; the outer wall of the extension portion 1501 is symmetrically provided with first limiting surfaces 15011, the distance between the first limiting surfaces 15011 is smaller than the diameter of the extension portion 1501, the distance between the first limiting surfaces 15011 is equal to the distance between the second limiting surfaces 24012, so that when the rotating assembly 13 is aligned with the housing 4 (the included angle is 0 ° or 180 ° or 360 °), the first limiting surfaces 15011 and the second limiting surfaces 24012 are aligned, that is, the rotating assembly 13 can be slid and reset, the rotating assembly 13 is locked, and the oil filling hole 402 is closed. Two oil holes 402 are symmetrically formed in the shell 4, when the oil hole 402 is opened by the rotary assembly 13, tobacco tar is added into the oil bin 5 through one of the oil holes 402 by a user, and air pressure in the oil bin 5 can be timely discharged through the other oil hole 402, so that the air pressure inside and outside the oil bin 5 is balanced, and the phenomenon that the tobacco tar is extruded onto the atomizing sheet 2 to generate oil soaking can be prevented.

As shown in fig. 7 and 8, the unlocking structure is another structure, which comprises a first protruding bone 15012 on the outer wall of the extension portion 1501, and a groove 24014 formed on the inner wall of the accommodating cavity 2401 and surrounded by two second protruding bones 24013, wherein the groove 24014 is formed by matching the first protruding bone 15012, and when the first protruding bone 15012 is blocked in the groove 24014, the locking ring 24 is locked; when the first male bone 15012 is disengaged from the groove 24014, the locking ring 24 is unlocked. The gear hand feeling is realized during locking and unlocking, and the experience is good.

The shell 4 is internally provided with an oil guide piece 1, an atomization piece 2 and an atomization seat 3 made of elastic materials, the atomization piece 2 is fixedly arranged on the atomization seat 3, and the oil guide piece 1 is contacted with an atomization surface of the atomization piece 2; the oil guide piece 1 is flaky atomized cotton, the atomizing seat 3 is provided with a through hole 301, the flaky oil guide piece 1 stretches across the atomizing sheet 2, passes through the through hole 301 and stretches out along the through hole 301, so that the length of the oil guide piece 1 is longer than the diameter of the atomizing seat 3, and the crossing part of the oil guide piece 1 is contacted with the atomizing sheet 2; the atomizing sheet 2 atomizes the tobacco tar on the oil guide 1 into smoke for a user to inhale in the high-frequency oscillation process, so that the smoke is sprayed out from the surface of the oil guide 1 corresponding to the atomizing sheet 2. An atomization upper cover 6 is arranged at the bottom of the shell 4, an oil outlet 601 which is communicated with the oil bin 5 and the oil guide piece 1 is formed in the atomization upper cover 6, and a perforation is formed in the central axis of the atomization upper cover 6.

In this embodiment, the atomizing base 3 is cylindrical for ease of assembly; the material of atomizing seat 3 is silica gel, because silica gel has certain elasticity, so when oil guide 1 passes through the through-hole 301 on the atomizing seat 3, frictional force reduces, oil guide 1 is difficult to be stretched, so oil guide 1 can keep original state, consequently, can control the extruded degree of compressing of oil guide 1 through the size of through-hole 301, and then the tobacco tar volume on the tobacco tar conducted to atomizing piece 2 from oil guide 1 in the control unit time, because oil guide 1 is not stretched, so oil guide 1 leads oil velocity stable, so the phenomenon that oil smoke volume and then can avoid atomizing piece 2 to easily bubble oil or dry combustion method is controlled through the size of adjusting through-hole 301, make the smoke volume stable unanimous.

The atomizing sheet 2 is a piezoelectric ceramic type or other type ultrasonic atomizing sheet, and the tobacco tar is ultrasonically atomized on the surface of the atomizing sheet 2.

When the atomizing piece 2 appears soaking oil phenomenon at high frequency oscillation atomizing in-process, atomizing piece 2 start-up speed is slow, and atomizing piece 2 high frequency oscillation makes the tobacco tar splash everywhere (just like boiling water that scalds splashes everywhere), consequently the user is easier to inhale the tobacco tar and scalded by the tobacco tar, consequently the cross-sectional area of through-hole 301 is the 0.3-8 times of the cotton 1 cross-sectional area of leading oil, the control flow through the tobacco tar volume of through-hole 301 in the unit time, say: under the condition of certain power, the starting speed of the ultrasonic atomization sheet 2 is related to the amount of tobacco tar to be atomized on the ultrasonic atomization sheet 2, and the atomization amount of the ultrasonic atomization sheet 2 per second is 0.2 mg-4 mg; therefore, the conduction rate of the tobacco tar is slightly faster than the atomization amount, namely 0.5 mg/s-5.5 mg/s.

The through hole 301 includes an upper hole face 3011 and a lower hole face 3012, for example, when the position of the lower hole face 3012 is fixed, the size of the through hole 301 is adjusted by raising or lowering the upper hole face 3011, so as to adjust the extrusion degree of the peripheral wall of the through hole 301 to the oil guide 1. When the lower hole face 3012 is level with the atomizing surface of the atomizing sheet 2, the oil way is not bent, so that the tobacco tar on the oil guide piece 1 flows through the through hole 301 to the atomizing sheet 2 smoothly, and the tobacco tar is more timely replenished in the working process of the atomizing sheet 2, so that the smoke quantity can be ensured, and the occurrence of dry burning can be prevented; in the non-working process of the atomizing sheet 2, the sheet-shaped oil guide piece 1 adsorbs tobacco tar in a balanced saturated state, so that the phenomenon of oil soaking can not occur. When the lower hole surface 3012 of the through hole 301 is higher or lower than the atomizing surface of the atomizing sheet 2, the oil guide 1 bends at the position of the through hole 301, so that the oil path bends, and the atomizing sheet 2 is in a balanced and saturated state when not working, so that the phenomenon of oil soaking caused by the fact that the sheet-shaped oil guide 1 adsorbs tobacco oil is avoided.

A bracket 7 and a cavity 8 are also arranged in the shell 4 (in the embodiment, the cavity 8 is surrounded by the shell 4, the atomization upper cover 6 and the bracket 7), one end of the bracket 7 is fixedly connected with the shell 4 through a limiting ring 15, the other end of the bracket 7 extends into a perforation of the atomization upper cover 6 and is opposite to an atomization surface of the atomization sheet 2, and a gap 9 for communicating the oil guide 1 or the atomization surface of the atomization sheet 2 with the cavity 8 is arranged between the outer wall of the bracket 7 and the perforation inner wall of the atomization upper cover 6; the outlet channel 23 of the atomizer is provided in the holder 7. When the inclined smoke evacuation or the atomizer is obliquely placed, tobacco tar on the atomizing sheet 2 can enter the cavity 8 in the shell 4 through the gap 9 between the outer wall of the bracket 7 and the inner wall of the atomizing upper cover 6, so that the problem that the atomizing sheet 2 is temporarily soaked in oil to start slow or the smoke output amount is small is solved, and meanwhile, the problem that excessive tobacco tar on the atomizing sheet 2 flows out to the oral cavity through the air outlet channel 23 in the bracket 7 to cause scalding of the oral cavity of a user can be avoided.

The atomizer also comprises a spring 10, one end of the spring 10 is connected with the bracket 7, and the other end of the spring 10 is abutted against the oil guide piece 1. The spring 10 can ensure that the oil guide piece 1 and the atomizing sheet 2 are reliably contacted; meanwhile, when the external force pressing the atomizing base 3 is removed during assembly, the restoring force of the spring 10 can also restore the atomizing base 3 and the through hole 301 thereof.

The limiting ring 15 is fixed on the housing 4, and the clamping part 1502 of the limiting ring 15 is clamped on the clamping table 1103 of the suction nozzle base 11, so as to prevent the limiting ring 15 from falling out of the suction nozzle base 11.

The suction nozzle sleeve 12, the suction nozzle base 11 and the lock ring 24 are fixedly connected together in a riveting mode and the like to form the rotary assembly 13, and the lock ring 24 can be rotated when the suction nozzle sleeve 12 is rotated, so that the oil filling hole 402 is conveniently opened.

A sealing ring 14 is arranged at the oil filling hole 402; during the rotation of the rotating assembly 13 and the opening or closing of the oil filler hole 402, the nozzle base 11 is always abutted against the edge of the sealing ring 14. During oiling, the rotary component 13 is driven to open the oil filling hole 402 by the rotary nozzle sleeve 12, and the edge of the nozzle base 11 always presses the edge of the sealing ring 14 in the process of rotating the rotary nozzle sleeve 12, so that the sealing ring 14 cannot fall out or wrinkle and deform in the process of rotating the rotary component 13, and smoke oil is conveniently added and sealing performance is improved.
