Wherein the pressure regulating assembly 30 includes an elastic body or an elastic member. The pressure regulating assembly 30 is disposed at or near the connection between the opening 111 and the reservoir 20.

The pressure regulating assembly 30 may be disposed within the opening 111; the pressure regulating assembly 30 can also be arranged at the opening of the hole 111 connected with the liquid storage bin 20; the pressure regulating subassembly 30 also can set up in stock solution storehouse 20, but the one end of pressure regulating subassembly 30 sets up in the opening part that trompil 111 and stock solution storehouse 20 are connected, designs as required, and this application does not do the restriction to this.

The atomizing base 11 is a supporting structure of the atomizing core 12. The atomizing core 12 arranged on the atomizing base 11 comprises a heating body and an atomizing body, wherein the heating body atomizes the liquid to be atomized flowing into the atomizing body from the liquid storage bin 20 so as to be used by a user. The reservoir 20 may be made of plastic, aluminum, stainless steel or other materials, and only needs to be able to store the liquid to be atomized without reacting with the liquid to cause the liquid to deteriorate. The shape and size of the reservoir 20 are not limited and can be designed as desired. The atomizing base 11 can be made of plastic, silica gel, ceramic, stainless steel or other alloys, and only needs to play a supporting role. The shape and size of the atomizing base 11 are not limited, and can be designed as required.

Wherein, adjust the space size in pressure regulating space through pressure regulating subassembly 30, and then adjust stock solution storehouse 20 space size to the regulation to the realization is to stock solution storehouse 20 internal gas pressure. For example, when the cartridge 1 is in a high-temperature and high-pressure state, the gas in the liquid storage bin 20 expands outwards, and the pressure regulating assembly 30 slides or contracts elastically in a direction away from the liquid storage bin 20, so that the space volume of the pressure regulating space is reduced, the space volume of the liquid storage bin 20 is increased, the pressure of the gas on the sealing parts of the atomizing base 11 and the inner wall of the liquid storage bin 20 is reduced, the pressure relief is realized, and the leakage situation is avoided. For another example, when the cartridge 1 is in a normal working state, since the liquid in the liquid storage bin 20 is consumed, the liquid cannot be supplemented in time, the air pressure in the liquid storage bin 20 becomes small, and the pressure regulating assembly 30 slides or expands elastically in a direction close to the liquid storage bin 20, so that the space volume of the pressure regulating space becomes large, the space volume of the liquid storage bin 20 becomes small, and the phenomenon of dry burning of the atomizing core is avoided.

When the opening 111 penetrates through the atomization upper seat and extends to the atomization base, but does not penetrate through the atomization base, the opening 111 is formed by a blind hole; through the atomizing base, the opening 111 is formed by a through hole. The opening 111 formed by the blind hole or the through hole is columnar, the extending direction of the blind hole or the through hole can be vertical to the atomizing base 11, a certain included angle can also be formed between the blind hole or the through hole and the atomizing base 11, and the extending direction of the blind hole or the through hole is preferably vertical to the atomizing base 11.

The through-holes or blind-holes forming the openings 111 may extend in a linear direction or may extend in a non-linear direction, preferably in a linear direction. The size of the opening 111 is designed according to the size of the atomizing base 11 and according to the need, and the present invention is not limited thereto.

When trompil 111 is formed by the through-hole that sets up on atomizing seat 11, trompil 111 and atomizing subassembly 10 intercommunication, pressure regulating space and atomizing subassembly 10 intercommunication promptly to because atomizing subassembly 10 and outside atmosphere intercommunication, or through the air inlet and the outside atmosphere intercommunication that set up, the gas pressure in the stock solution storehouse 20 is in balanced state through the slip of pressure regulating subassembly 30, elastic shrinkage or inflation and outside atmospheric pressure. When the opening 111 is formed by a blind hole formed on the atomizing base 11, the gas pressure in the liquid storage bin 20 is in a balanced state with the gas pressure in the pressure regulating space and the elasticity of the pressure regulating assembly 30 through the sliding, elastic contraction or expansion of the pressure regulating assembly 30. The pressure regulating space that the trompil 111 formed when being the through-hole is the pressure regulating space that the blind hole formed than trompil 111, can realize the constant voltage and adjust, more is favorable to relieving pressure in the stock solution storehouse 20.

In the first embodiment, the pressure regulating assembly 30 includes the piston 31 and the elastic member 32, the pressure regulating assembly 30 is disposed in the opening 111, and the opening 111 is a cylindrical through hole and extends perpendicular to the atomizing base 11.

The piston 31 includes a piston body 311 and a protrusion 312, and the protrusion 312 is disposed at one end of the piston body 311 away from the reservoir 20. The piston body 311 and the bulge 312 are both cylinders, and the section diameter of the bulge 312 is smaller than that of the piston body 311; the protrusion 312 may also be a column with a square or other cross-section, and the cross-section of the protrusion 312 is smaller than that of the piston body 311. The outer diameter of the piston body 311 is smaller than the inner diameter of the opening 111 so that the piston 31 can slide along the inner wall of the opening 111. The elastic element 32 is sleeved on the protrusion 312, and one end of the elastic element is fixed on the piston body 311, when the opening 111 is formed by a through hole, the other end of the elastic element 32 is fixed on a connecting part of the opening 111 and the atomizing assembly 10 or a limiting element on the inner wall of the opening 111 close to the atomizing assembly 10; when the opening 111 is formed by a blind hole, the other end of the elastic member 32 is fixed to the bottom of the opening 111.

The piston 31 may be made of plastic, metal or other light materials, so that the elastic member 32 can drive the piston 31 to slide; the elastic member 32 may be a spring or other elastic deformable and resilient object, which is not limited in the invention.

It is understood that when the opening 111 is formed of a through hole, the pressure regulating member 30 is a piston 31 and can slide with respect to the inner wall of the opening 111, and the elastic member 32 can be omitted. The opening 111 is formed by a through hole, the pressure regulating space is communicated with the atomization assembly 10, the atomization assembly 10 is communicated with the external atmosphere, and the piston 31 slides on the inner wall of the opening 111 under the action of the pressure difference between the air pressure in the liquid storage bin 20 and the external atmosphere. The piston 31 may be made of plastic, metal, or other light materials, so that the piston 31 can slide on the inner wall of the opening 111 under the action of the pressure in the liquid storage 20 and the pressure difference between the outside atmosphere, so as to adjust the pressure in the liquid storage 20.

Further, a sealing element 313 can be arranged between the piston 31 and the inner wall of the opening 111 to prevent liquid inside the liquid storage bin 20 from leaking into the opening 111 and affecting the regulation of the pressure regulating assembly 30 on the air pressure inside the liquid storage bin 20.

Please refer to fig. 2, which is a schematic diagram illustrating a change of a first embodiment of a liquid leakage prevention cartridge 1 according to the present invention before and after pressure release.

Under normal temperature and pressure, the volume of the internal space of the liquid storage bin 20 is V1. When the inside of the cartridge 1 is at high temperature and high pressure, the gas inside the liquid storage bin 20 expands, and the expanded gas volume is V2(V2> V1). The piston 31 is impacted by the air pressure caused by the expansion of the air, and slides in the direction away from the liquid storage bin 20 along with the increase of the air pressure in the liquid storage bin 20, meanwhile, the elastic piece 32 is elastically deformed, and after the piston 31 stops sliding, the space volume of the pressure regulating space is reduced by V3, and the space volume of the corresponding liquid storage bin 20 is increased by V3. When V1+ V3 is V2, the air pressure inside the liquid storage bin 20 reaches equilibrium, and the expanded air no longer impacts each sealing area and inner wall of the liquid storage bin 20; when V1+ V3< V2, the gas pressure inside the liquid storage bin 20 is reduced, the impact on each sealing area and inner wall of the liquid storage bin 20 is reduced, and liquid leakage is avoided. When the temperature and the pressure inside the liquid storage bin 20 are restored to the normal state, the air pressure in the liquid storage bin 20 is reduced, the air pressure received by the piston 31 from one side of the liquid storage bin 20 is reduced, the piston 31 slides towards the direction close to the liquid storage bin 20 under the action of the elastic piece 32, the space volume of the pressure regulating space is increased, the space volume in the liquid storage bin 20 is correspondingly reduced, and the air pressure in the liquid storage bin 20 is increased.

It can be understood that the piston 31 is impacted by the air pressure caused by the expansion of the air in the liquid storage bin 20 and slides in the direction far away from the liquid storage bin 20, when the pressure regulating assembly 30 comprises the piston 31 and the elastic member 32, the piston 31 stops sliding when the air pressure in the liquid storage bin 20, the air pressure in the pressure regulating space and the elastic force of the elastic member 32 reach a balanced state; when the pressure regulating assembly 30 includes the piston 31 and the elastic member 32 is omitted, the piston 31 stops sliding when the air pressure in the liquid storage chamber 20 and the air pressure in the pressure regulating space reach a balanced state.

Along with stock solution storehouse 20 inside liquid reduces, the inside gas pressure of stock solution storehouse 20 reduces, and piston 31 slides to the direction that is close to stock solution storehouse 20 along with the reduction of the interior gas pressure of stock solution storehouse 20 under the effect of elastic component 32 to the space volume in increase pressure regulating space reduces the space volume of stock solution storehouse 20, and increase atmospheric pressure avoids liquid to obtain supplementing and leads to atomizing core dry combustion method, produces burnt flavor, influences the experience sense that the user used.

When the air pressure in the liquid storage bin 20 is increased, the pressure regulating assembly 30 is elastically deformed and shrinks towards the direction far away from the liquid storage bin 20, the space volume of the pressure regulating space is reduced, and the space volume of the liquid storage bin 20 is correspondingly increased; when stock solution storehouse 20 internal gas pressure reduces, the performance that pressure regulating subassembly 30 utilized elastomer elastic deformation can the reconversion expands to the direction that is close to stock solution storehouse 20, and the space volume in pressure regulating space increases, and the space volume of stock solution storehouse 20 correspondingly reduces to the state of resumeing from the factory. The elastic body can be made of rubber or other materials, and the adjustment of the air pressure in the liquid storage bin 20 can be realized only by meeting the requirements that the elastic body can contract along with the increase of the air pressure in the liquid storage bin 20 and expand along with the decrease of the air pressure in the liquid storage bin 20, which is not limited by the invention. In this embodiment, the pressure relief principle is the same as that of the first embodiment, and is not described herein again.

Please refer to fig. 6, which is a schematic diagram illustrating a change of a third embodiment of a liquid leakage prevention smoke bomb according to the present invention before and after pressure release.

Under normal temperature and pressure, the volume of the internal space of the liquid storage bin 20 is V1. When the inside of the cartridge 1 is at high temperature and high pressure, the gas inside the liquid storage bin 20 expands, and the expanded gas volume is V2(V2> V1).

When V1+ V3 is V2, the gas in the liquid storage bin 20 reaches balance, and the expanded gas does not impact the inner wall of the liquid storage bin 20 and each sealing area; when V1+ V3< V2, the gas pressure in the liquid storage bin 20 is reduced, the impact on the inner wall of the liquid storage bin 20 and each sealing area is reduced, and liquid leakage is avoided. When the inside temperature of stock solution storehouse 20 and pressure resume normal state, the gas pressure that the elastic membrane received reduces, and along with atmospheric pressure in the stock solution storehouse 20 reduces and expand to the reconversion to the direction that is close to stock solution storehouse 20, the spatial volume increase in pressure regulating space, and the spatial volume of stock solution storehouse 20 reduces to the state of leaving the factory.

Along with stock solution storehouse 20 inside liquid reduces, the inside gas pressure of stock solution storehouse 20 reduces, and elastic deformation takes place to the direction that is close to stock solution storehouse 20 along with the reduction of the interior gas pressure of stock solution storehouse 20 to the space volume in increase pressure regulating space reduces the space volume in stock solution storehouse 20, and increase atmospheric pressure avoids liquid to obtain supplementing to lead to atomizing core dry combustion method, produces burnt flavor, influences the experience sense that the user used.
