[0034] See also Figure 1 , Figure 1 The schematic diagram of the structure of the atomizing device 100 in one embodiment of the present application is shown. One embodiment of the present application provides an atomizing device 100 for heating an aerosol generating substrate to generate an aerosol for use by a user. The heating method may be convection, conduction, radiation, or a combination thereof. The aerosol generating substrate may be in the form of a liquid, gel, paste, or solid. The aerosol generating substrate includes, but is not limited to, a material for medical, health, health, and beauty purposes. For example, the aerosol generating substrate may be a medicinal liquid or oil.
[0035] The atomizing device 100 is generally in a columnar structure. In the following embodiments, the length direction of the atomizing device 100 is defined as a first direction (i.e. Figure 1 The width direction of the atomizing device 100 is the second direction (i.e. Figure 2 The height direction of the atomizing device 100 is the third direction (i.e. Figure 1 The first direction, the second direction and the third direction intersect each other. As a preferred embodiment, the first direction, the second direction and the third direction are perpendicular to each other.
[0036] The atomizing device 100 includes a housing 10 and a main body. The housing 10 is a hollow shell structure. The main body is at least partially contained in the housing 10. The main body includes an atomizer 20 and a battery assembly 60. The atomizer 20 and the battery assembly 60 are arranged adjacent to each other in a first direction. The liquid storage tank 40 is used to store an aerosol generating matrix. The battery assembly 60 is electrically connected to the atomizer 20 to power the atomizer 20. The atomizer 20 can heat the atomized aerosol under the action of electric energy to generate an aerosol for the user to take. In some embodiments, the liquid storage tank 40 can be disassembled and replaced to replenish a new aerosol generating matrix.
[0037] See also Figure 1 and Figure 2 The atomizer 20 includes a housing 21, an atomizer assembly 22, and a liquid storage tank 40. The housing 21 includes an atomizer base 211 and an atomizer upper cover 212, which are connected to each other by a snap connection or other connection methods. The atomizer base 211 and the atomizer upper cover 212 jointly form an atomizer chamber 21a and a liquid inlet channel 21b that are adjacently arranged in the first direction, and the atomizer chamber 21a is located on the same side of the main body as the battery assembly 60 in the first direction. The atomizer assembly 22 is accommodated in the atomizer chamber 21a and is electrically connected to the battery assembly 60. The liquid storage tank 40 is connected to a side of the atomizing base 211 close to the liquid inlet channel 21b in the first direction and is spaced apart from the battery assembly 60 in the first direction. One end of the liquid inlet channel 21b is connected to the liquid storage tank 40. The aerosol generating matrix in the liquid storage tank 40 can flow into the shell 21 through the liquid inlet channel 21b, and then enter the atomizing assembly 22 in the atomizing chamber 21a to supply liquid to the atomizing assembly 22.
[0038] Furthermore, in order to realize the automatic liquid injection function of the atomizing device 100, the housing 21 is also provided with an installation cavity 21c located between the liquid inlet channel 21b and the liquid storage tank 40 in the first direction, and the installation cavity 21c is provided with a first liquid injection port 212a connected to the liquid storage tank 40 through the liquid inlet channel 21b on one side facing the liquid inlet channel 21b in the third direction, and the installation cavity 21c is provided with a second liquid injection port 212b connected to the atomizing chamber 21a on one side close to the atomizing chamber 21a in the first direction. The atomizer 20 also includes a liquid injection member 23, which is rotatably received in the installation cavity 21c, and the liquid injection member 23 has a liquid injection cavity 23a connected to the second liquid injection port 212b, and the liquid injection cavity 23a has a lower liquid port 234a (such as Figure 4 shown).
[0039] Please combine Figure 3As shown, the liquid injection member 23 can rotate between a first angle and a second angle. When the liquid injection member 23 is at the first angle, the lower liquid port 234a is misaligned with the first liquid injection port 212a to close the first liquid injection port 212a, so that the aerosol generating substrate in the liquid storage tank 40 cannot flow into the liquid injection cavity 23a. When the liquid injection member 23 is at the second angle, the lower liquid port 234a is communicated with the first liquid injection port 212a, so that the aerosol generating substrate in the liquid storage tank 40 can enter the liquid injection cavity 23a through the liquid inlet channel 21b, the first liquid injection port 212a, and the lower liquid port 234a, and then enter the atomization cavity 21a through the second liquid injection port 212b.
[0040] In this way, when the atomizer 20 needs an aerosol-generating matrix, the first liquid injection port 212a can be opened to allow the aerosol-generating matrix in the liquid storage tank 40 to flow into the atomizing assembly 22, thereby preventing the atomizing assembly 22 from being immersed in the aerosol-generating matrix for a long time, which can effectively reduce leakage and improve the taste of atomization. Moreover, the assembly method of the liquid injection part 23 in the present application, which realizes the opening and closing of the first liquid injection port 212a by rotation, is simpler and more reliable in sealing, and no high-precision shaft hole matching is required to ensure the position accuracy of the liquid injection structure. In addition, the pressure change in the atomizing chamber 21a and the liquid storage tank 40 caused by the up and down movement of the liquid injection structure can be avoided, which causes leakage of the aerosol-generating matrix, effectively optimizing the user experience.
[0041] Please continue reading Figure 1 and Figure 2 , the atomizer 20 also includes a control member 25 for driving the injection member 23 to rotate. The control member 25 is mounted on the housing 21 and is located on a side of the injection member 23 away from the atomization chamber 21a in the first direction. The control member 25 can move back and forth in a straight line under the action of an external force to switch between the first position and the second position. When the control member 25 is in the first position, the injection member 23 is at a first angle to close the first injection port 212a. When the control member 25 is in the second position, the injection member 23 is at a second angle to open the first injection port 212a. Specifically in some embodiments, the moving direction of the control member 25 is perpendicular to the extension direction of the rotation axis of the injection member 23. More specifically, in the following embodiments, the control member 25 moves back and forth in a straight line along a third direction, and the rotation axis of the injection member 23 extends along the first direction.
[0042] In some embodiments, the installation cavity 21c is located on one side of the atomizing cavity 21a in the first direction, and a communication port is provided on the side of the installation cavity 21c facing away from the atomizing cavity 21a in the first direction. The housing 21 is recessed inward on one side away from the atomizing cavity 21a in the first direction to form an installation position 21d for limiting the control member 25, and the communication port of the installation cavity 21c is connected to the installation position 21d. In this way, the liquid injection member 23 is inserted into the installation cavity 21c along the first direction through the communication port, and after the liquid injection member 23 is accommodated in the installation cavity 21c, the control member 25 can be limited in the installation position 21d.
[0043] Please combine Figure 1 , Figure 2 as well as Figure 4 As shown, the injection member 23 is a cylindrical structure, including a bottom wall 232 and a side wall 234 extending from the edge of the bottom wall 232 in the same direction. The side wall 234 surrounds the bottom wall 232 in the circumferential direction to form an injection cavity 23a with one end open. The central axis of the injection member 23 extends in the first direction, and the open end of the injection cavity 23a faces the second injection port 212b of the housing 21 to communicate with the atomization cavity 21a. The lower liquid port 234a is formed on the side wall 234 of the injection member. As the injection member 23 rotates, the relative position of the lower liquid port 234a and the first injection port 212a changes, thereby changing the opening and closing state of the first injection port 212a. Furthermore, since the liquid injection member 23 is always in contact with the cavity wall of the installation cavity 21c having the first liquid injection port 212a through the liquid injection member side wall 234 during the rotation process, the pressure in the liquid storage bin 40 and the atomization cavity 21a will not be affected.
[0044] Further, a positioning shaft 2121 is also provided in the injection chamber 23a, one end of the positioning shaft 2121 is connected to a side wall of the injection chamber 23a close to the atomization chamber 21a, and the other end of the positioning shaft 2121 extends along the first direction. The injection member 23 also includes a mounting shaft 236, which is located in the injection chamber 23a, one end of the mounting shaft 236 is connected to the center position of the injection member bottom wall 232, and the other end of the mounting shaft 236 extends along the central axis of the injection member 23 and is sleeved outside the positioning shaft 2121. In this way, the injection member 23 is limited in the installation chamber 21c by the positioning shaft 2121 and can rotate around the positioning shaft 2121. The positioning shaft 2121 is used to position the injection member 23 to prevent the injection member 23 from moving in the radial direction and the axial direction during the rotation process.
[0045] As a preferred embodiment, the atomizer 20 further includes a liquid injection seal 24, which is a hollow cylindrical structure, and is sleeved outside the liquid injection side wall 234 of the liquid injection part 23. The liquid injection seal 24 is provided with a communication hole connected to the lower liquid port 234a. The liquid injection seal 24 can undergo a certain degree of elastic deformation under the action of an external force, so that a good seal is formed between the liquid injection part 23 and the cavity wall of the installation cavity 21c, effectively preventing leakage of the aerosol generating substrate.
[0046] Please combine Figure 1 , Figure 2 as well as Figure 5 As shown, the control member 25 includes a mounting post 252 and a control portion 254 disposed at one end of the mounting post 252, and one end of the mounting post 252 away from the control portion 254 is inserted into the housing 21 along the third direction. As a preferred embodiment, the control member 25 also includes a sealing ring 256, and one end of the mounting post 252 inserted into the housing 21 is provided with a limiting groove 254a extending in the circumferential direction, and the sealing ring 256 is sleeved on the mounting post 252 and partially limited in the limiting groove 254a, and is used to close the gap between the mounting post 252 and the housing 21, thereby preventing the aerosol generating substrate from leaking through the gap between the mounting post 252 and the housing 21.
[0047] In order to realize the transmission connection between the operating member 25 and the injection member 23, one of the operating member 25 and the injection member 23 is provided with a limiting protrusion 2321, and the other of the operating member 25 and the injection member 23 is provided with a limiting groove 254a, the limiting protrusion 2321 is inserted into the limiting groove 254a, and the limiting protrusion 2321 and the limiting groove 254a are both eccentrically arranged relative to the rotation axis of the injection member 23. In this way, when the operating member 25 moves along the first direction, the limiting protrusion 2321 can be driven to move in the first direction, and because the injection member 23 is limited by the positioning shaft 2121, the injection member 23 rotates around the positioning shaft 2121 under the drive of the operating member 25.
[0048] Specifically in one embodiment, the limiting protrusion 2321 is formed on the bottom wall 232 of the liquid injection member 23, the limiting groove 254a is formed on the side of the control portion 254 of the control member 25 facing the liquid injection member 23, and the limiting groove 254a is a long groove extending along the second direction, so the limiting protrusion 2321 is allowed to have a certain degree of freedom in the second direction. Therefore, driven by the control member 25, the limiting protrusion 2321 limited in the limiting groove 254a moves along the first direction and the second direction, and the liquid injection member 23 rotates around the positioning shaft 2121 as a whole.
[0049] In some embodiments, the atomizer 20 further includes a reset member 26, which is held between the control member 25 and the housing 21, and is used to apply a force to the control member 25 to move it from the second position to the first position. Specifically, in some embodiments, the reset member 26 is a spring, which is sleeved on the mounting post 252, and one end of the reset member 26 is held against an end surface of the control portion 254 connected to the mounting post 252, and the other end of the reset member 26 is held against the housing 21.
[0050] In this way, when the user does not apply pressure to the operating member 25, the operating member 25 maintains the first position under the support of the reset member 26, at which time the liquid injection member 23 is at the first angle, and the lower liquid port 234a is misaligned with the first liquid injection port 212a to close the first liquid injection port 212a. When the operator applies a certain pressure along the third direction to the operating member 25, the operating member 25 overcomes the force of the reset member 26 and moves along the third direction until it reaches the second position, at which time the reset member 26 is in a compressed state, and the liquid injection member 23 rotates to the second angle under the drive of the operating member 25, and the lower liquid port 234a is correspondingly connected to the first liquid injection port 212a.
[0051] It can be understood that, as a preferred embodiment, the movement stroke of the operating member 25 in the third direction just meets the opening and closing requirements of the first liquid injection port 212a, thereby avoiding the operating member 25 from having too large a stroke and occupying too much space, and optimizing the operating experience of the operating member 25. That is, when the operating member 25 is in the first position, the liquid injection member 23 is at the first angle, the lower liquid port 234a is located at the outer edge of the first liquid injection port 212a, and the overlap area of the lower liquid port 234a and the first liquid injection port 212a is 0. When the operating member 25 is in the second position, the liquid injection member 23 is at the second angle, and the overlap area of the lower liquid port 234a and the first liquid injection port 212a reaches the maximum value.
[0052] The automatic liquid injection principle of the above-mentioned atomizer 20 is as follows:
[0053] When liquid injection is needed, the user presses the operating member 25 along the third direction to switch the operating member 25 from the first position to the second position. The operating member 25 overcomes the force of the reset member 26 and moves along the third direction, driving the liquid injection member 23 to rotate from the first angle to the second angle. The lower liquid port 234a on the liquid injection member 23 is aligned with the first liquid injection port 212a. Therefore, the aerosol generating matrix in the liquid inlet channel 21b flows into the atomization chamber 21a through the first liquid injection port 212a, the lower liquid port 234a, the liquid injection chamber 23a, and the second liquid injection port 212b under the action of gravity to infiltrate the atomization component 22.
[0054] When the injection is stopped, the user releases the operating member 25, and the reset member 26 drives the operating member 25 to move in the opposite direction along the third direction from the second position to the first position, driving the injection member 23 to rotate in the opposite direction and return from the second angle to the first angle. The lower liquid port 234a on the injection member 23 is misaligned with the first injection port 212a, so the aerosol generating matrix in the liquid inlet channel 21b cannot enter the injection cavity 23a through the lower liquid port 234a.
[0055] The above-mentioned atomizer 20 and atomizing device 100 convert the linear motion of the control member 25 into the rotational motion of the liquid injection member 23, thereby realizing the automatic liquid injection function. Since the first liquid injection port 212a is only opened when the atomizer 20 needs an aerosol generating matrix, the atomizing assembly 22 can be prevented from being immersed in the aerosol generating matrix for a long time, which can effectively reduce leakage and improve the taste of atomization. Moreover, since the side wall of the liquid injection member 23 is always in contact with the cavity wall provided with the first liquid injection port 212a, it has a good sealing effect, and the movement of the liquid injection member 23 will not affect the pressure in the liquid storage tank 40 and the atomizing cavity 21a, effectively preventing the leakage of the aerosol generating matrix. In addition, the structure of the atomizer 20 is simple and reliable, and the liquid injection member 23 and the control member 25 can be directly inserted in the corresponding position, which simplifies the assembly process of the atomizer 20.
[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0057] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
