Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an electronic atomization device. Background Technology

[0002] Electronic atomizing devices typically consist of a liquid reservoir and an atomizing chamber. The atomizing chamber contains an atomizing cavity, where the atomizing components are housed. The liquid reservoir stores the atomizing matrix, communicates with the atomizing cavity, and replenishes the atomizing matrix. Because the atomizing cavity is not a completely sealed structure, under negative pressure or high temperature environments, increased pressure within the atomizing cavity can easily lead to atomizing matrix leakage.

[0003] To address these issues, existing technologies typically employ two methods. The first involves incorporating a switch mechanism within the electronic atomizing device. When vaping is needed, the switch is activated to open the liquid outlet of the reservoir; after vaping, the switch closes the outlet. This design is cumbersome for consumers, and if the switch is forgotten during vaping, the atomizing component may burn out due to dry burning. The second method involves installing a pump mechanism within the electronic atomizing device. When vaping is initiated, the pump is activated to draw in liquid. However, due to the large size and high cost of pumps, their application in electronic atomizing devices is economically inefficient. Utility Model Content

[0004] Instead of setting up an external accommodating channel to connect to an external drive switch, thereby driving the internal blocking component and making it easy for the internal atomizing matrix to leak through the gaps in the accommodating channel, this application provides an electronic atomizing device that uses a built-in solenoid valve assembly to open or close the liquid guiding channel, which can reduce the risk of atomizing matrix leakage.

[0005] The first aspect of this application provides an electronic atomizing device, comprising: a liquid storage chamber for storing an atomizing matrix; an atomizing chamber disposed at one end of the liquid storage chamber, the atomizing chamber having an atomizing cavity for atomizing the atomizing matrix; a liquid inlet channel disposed between the atomizing chamber and the liquid storage chamber for connecting the atomizing chamber and the liquid storage chamber; a liquid guide tube disposed within the atomizing chamber; one end of the liquid guide tube communicating with the liquid inlet channel, the wall of the liquid guide tube having a liquid guide hole; and a solenoid valve assembly, at least partially located within the liquid guide tube, configured to either block or expose the liquid guide hole; wherein, when the liquid guide hole is exposed, at least a portion of the atomizing matrix in the liquid storage chamber can flow into the atomizing chamber.

[0006] In some embodiments, the solenoid valve assembly is configured to switch between a first position and a second position; when the solenoid valve assembly is in the first position, the solenoid valve assembly is at least partially housed in the liquid guide tube to block the liquid guide hole; when the solenoid valve assembly is in the second position, the solenoid valve assembly moves toward the end away from the liquid inlet channel to expose the liquid guide hole.

[0007] In some embodiments, the solenoid valve assembly includes: a sensing element disposed at one end of the atomizing chamber away from the liquid storage chamber and configured to generate a variable magnetic field; a magnetic attracting element disposed within a liquid guide tube and configured to displace in response to the variable magnetic field; and an elastic element at least partially disposed within the liquid guide tube and abutting against the sensing element and the magnetic attracting element respectively; wherein the magnetic attracting element is displaced from a first position to a second position in response to the variable magnetic field.

[0008] In some embodiments, the solenoid valve assembly further includes a guide, one end of which is connected to the sensing element and the other end of which extends into the liquid guide tube; wherein the guide is configured to define a displacement path for the magnetic element.

[0009] In some embodiments, the magnetic attractor includes: a first sealing member disposed within a liquid guide tube, the first sealing member being configured to adhere to the inner wall of the liquid guide tube; and a magnetic member disposed within the first sealing member, configured to displace in response to a variable magnetic field; wherein, when the magnetic member is in a first position, the sidewall of the first sealing member can block the liquid guide hole.

[0010] In some embodiments, the device further includes a second seal disposed between the sensor and the atomizing chamber for sealing the atomizing chamber.

[0011] In some embodiments, the device further includes: a liquid storage element disposed within an atomizing chamber for adsorbing the atomizing matrix; and an atomizing assembly disposed within an atomizing cavity for atomizing the atomizing matrix; wherein the liquid storage element is configured to at least partially cover the liquid guiding hole to guide the atomizing matrix to the atomizing assembly.

[0012] In some embodiments, it further includes: a third sealing element disposed between the atomizing chamber and the liquid storage chamber, forming a liquid inlet channel; wherein the liquid guide tube is at least partially housed within the liquid inlet channel.

[0013] In some embodiments, the liquid storage tank is formed with an air outlet channel, one end of which passes through a third seal and is connected to the atomizing chamber.

[0014] In some embodiments, the liquid storage tank is provided with a replenishment port, which is configured to replenish the liquid storage tank with atomizing medium.

[0015] This application provides an electronic atomizing device, which includes a liquid storage chamber, an atomizing chamber, a liquid inlet channel, a liquid guide tube, and a solenoid valve assembly. The liquid storage chamber and the atomizing chamber are connected through the liquid inlet channel. The liquid guide tube is disposed inside the atomizing chamber, with one end connected to the liquid inlet channel. The solenoid valve assembly is at least partially located inside the liquid guide tube and is configured to either block or expose the liquid guide hole. Through the coordinated arrangement of the liquid guide hole in the liquid guide tube and the solenoid valve assembly, this application ensures that the atomizing matrix in the liquid storage chamber will not flow into the atomizing chamber before the electronic atomizing device is activated or not in use. Only during inhalation will the solenoid valve assembly open the liquid guide hole according to the number of inhalations or the situation, allowing the liquid storage chamber to supply the atomizing matrix to the atomizing chamber. This minimizes the problem of atomizing matrix leakage, prevents coil clogging, and reduces the cost of the electronic atomizing device. Attached Figure Description

[0022] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0023] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0024] One embodiment of this application provides an electronic atomizing device 100. Please refer to [link / reference]. Figure 1-4 The electronic atomizing device 100 includes a liquid storage chamber 110, an atomizing chamber 120, a liquid inlet channel 130, a liquid guide tube 140, and a solenoid valve assembly 150.

[0025] Please refer to Figure 2-3 The liquid storage chamber 110 stores the atomizing matrix. An atomizing chamber 120 is located at one end of the liquid storage chamber 110 and includes an atomizing cavity 121 for atomizing the matrix. An inlet channel 130 connects the atomizing chamber 120 and the liquid storage chamber 110. A liquid guide pipe 140 is located within the atomizing chamber 120, with one end connected to the inlet channel 130. A liquid guide hole 141 is provided on the wall of the liquid guide pipe 140. A solenoid valve assembly 150 is at least partially located within the liquid guide pipe 140 and is configured to either block or expose the liquid guide hole 141. When the liquid guide hole 141 is exposed, at least a portion of the atomizing matrix in the liquid storage chamber 110 can flow into the atomizing chamber 120.

[0026] In one embodiment, by providing a liquid inlet channel 130 between the atomizing chamber 120 and the liquid storage chamber 110, and placing a liquid guide tube 140 within the atomizing chamber 120, the solenoid valve assembly 150 is at least partially located within the liquid guide tube 140 and configured to either block or expose the liquid guide hole 141. Before the electronic atomizing device 100 is activated, and when activated but not in use, the solenoid valve assembly 150 can close the liquid guide hole 141, preventing the atomizing matrix from entering the atomizing chamber 121, thus minimizing the risk of leakage of the atomizing matrix during transportation.

[0027] In one embodiment, the solenoid valve assembly 150 can be configured to respond to the user's suction action without manual control. When the number of suctions reaches a predetermined value, the solenoid valve assembly 150 responds to the circuit board 250 to expose the liquid guide hole 141, so that the atomizing matrix in the liquid storage chamber 110 enters the intermediate atomizing chamber 120 through the liquid guide hole 141. This can prevent the coil from clogging, and the solenoid valve assembly 150 has low cost, which can reduce the cost of the electronic atomization device 100.

[0028] Please refer to Figure 3-4 The solenoid valve assembly 150 is configured to switch between a first position and a second position. For example... Figure 4 When the solenoid valve assembly 150 is in the first position, the solenoid valve assembly 150 is at least partially contained in the liquid guide tube 140 to block the liquid guide hole 141; as Figure 3 When the solenoid valve assembly 150 is in the second position, the solenoid valve assembly 150 moves toward the end away from the liquid inlet channel 130 to expose the liquid guide hole 141.

[0029] The liquid guide hole 141 can be closed and opened by moving the solenoid valve assembly 150 in the first and second positions, and the working process is simple.

[0030] In one embodiment, the solenoid valve assembly 150 is signal-driven and is entirely located inside the electronic atomizing device 100, eliminating the need for a drive switch to connect to the outside. This structural design prevents the atomizing matrix from flowing out of the drive switch gap.

[0031] This can be understood as follows: the liquid inlet channel 130 connecting the liquid storage chamber 110 and the atomizing chamber 120, as well as the liquid guide tube 140, are all located inside the electronic atomizing device 100. The solenoid valve assembly 150 is also completely located inside the electronic atomizing device 100, and none of the three have any direct connection to the outside. The solenoid valve assembly 150 only needs to respond to the suction action to undergo relative displacement within the liquid guide tube 140 to complete the atomization matrix replenishment action, thereby reducing the risk of oil leakage through structural design.

[0032] Please refer to Figure 3The solenoid valve assembly 150 includes a sensing element 151, a magnetic attracting element 152, and an elastic element 153. The sensing element 151 is disposed at the end of the atomizing chamber 120 away from the liquid storage chamber 110 and is configured to generate a variable magnetic field. The magnetic attracting element 152 is disposed within the liquid guide tube 140 and is configured to displace in response to the variable magnetic field. The elastic element 153 is at least partially disposed within the liquid guide tube 140 and abuts against both the sensing element 151 and the magnetic attracting element 152. The magnetic attracting element 152 can displace from a first position to a second position in response to the variable magnetic field.

[0033] The sensor 151 is an electromagnetic induction structure. By applying a variable current to the sensor 151, a magnetic field can be generated, thereby controlling the movement of the magnetic suction component 152. It does not require manual intervention. When a suction action occurs, a corresponding induction signal is generated and transmitted to the circuit board 250. The circuit board 250 responds to the induction signal and the preset threshold to control the working state of the solenoid valve assembly 150, thereby controlling the replenishment of the atomizing matrix.

[0034] It can be understood that the solenoid valve assembly 150 also includes a body 154, which is used for electrical connection with the circuit board 250. The circuit board 250 responds to the suction action and generates a current signal corresponding to the variable magnetic field. The body 154 transmits the corresponding current signal to the coil (not shown) in the sensing element 151. After receiving the current signal, the coil generates the corresponding variable magnetic field. The magnetic suction element 152 moves from the first position to the second position under the influence of the variable magnetic field. The first sealing element 1521 follows the magnetic suction element 152 from the first position to the second position, exposing the liquid guide hole 141, thereby opening the liquid storage chamber 110 and the atomizing chamber 120.

[0035] In one embodiment, the coil (not shown) may be wound around an iron core (not shown), which is made of soft iron or silicon steel, to enhance the magnetic field strength. When the coil is de-energized, the magnetic field it generates disappears.

[0036] Please refer to Figure 3 The solenoid valve assembly 150 also includes a guide 155, one end of which is connected to the sensing element 151, and the other end extends into the liquid guide tube 140. The guide 155 is configured to define the displacement path of the magnetic attractor 152.

[0037] The elastic element 153 is a spring, which is sleeved on the guide element 155. The guide element 155 can stabilize the movement path of the magnetic attractor 152.

[0038] For example, when the magnetic attractor 152 moves from the first position to the second position under the influence of a variable magnetic field, the elastic element 153 is in a compressed state, and the liquid storage chamber 110 replenishes the atomizing matrix to the atomizing chamber 120. After the replenishment time limit is reached, the circuit board 250 stops generating the current signal corresponding to the variable magnetic field, the sensing element 151 no longer generates the variable magnetic field, and under the elastic reset force of the elastic element 153, the magnetic attractor 152 is pushed from the second position to the first position to block the liquid guiding channel.

[0039] Please refer to Figure 3 In some embodiments, the liquid guide hole 141 is disposed in the middle region of the liquid guide tube 140. The first position is the end of the liquid guide tube 140 near the liquid storage chamber 110, and the second position is the end of the liquid guide tube 140 near the atomizing chamber 120. By controlling the magnetic suction component 152 to switch between the first position and the second position, the communication state between the liquid guide hole 141 and the liquid storage chamber 110 can be changed.

[0040] In addition, a sealing ring (not shown) is provided on the outer wall of the magnetic attractor 152. This seal abuts against the inner wall of the liquid guide tube 140 while reducing the contact area between the two, thereby reducing friction. By appropriately reducing friction, it is prevented that excessive friction would prevent the pushing force generated by the elastic reset of the elastic member 153 from failing to push the magnetic attractor 152 from the second position to the first position.

[0041] In some modified embodiments, the surface of the sealing ring may deform or wear during the continuous back-and-forth movement of the magnetic attractor 152. The number of sealing rings is set to at least two to further optimize the sealing effect and ensure that the atomizing matrix does not leak from the gap between the liquid guide tube 140 and the sealing ring when the solenoid valve assembly 150 is in the first position.

[0042] In one embodiment, the magnetic attractor 152 includes a first sealing element 1521 and a magnetic element 1522. The first sealing element 1521 is disposed within the liquid guide tube 140 and is configured to fit against the inner wall of the liquid guide tube 140. The magnetic element 1522 is disposed within the first sealing element 1521 and is configured to displace in response to a variable magnetic field. When the magnetic element 1522 is in a first position, the sidewall of the first sealing element 1521 can block the liquid guide hole 141.

[0043] That is, by setting the magnetic suction member 152 so that when the magnetic suction member 152 is in the first position, the side wall of the first sealing member 1521 at least partially covers or blocks the liquid guiding hole, thereby achieving the separation of the liquid storage chamber 110 and the atomizing chamber 120.

[0044] like Figure 3Alternatively, in configuration 4, the magnetic component 1522 is enclosed by the first sealing component 1521. Both the first sealing component 1521 and the magnetic component 1522 are annular structures, allowing the guide component 155 to pass through, thus defining the displacement path of both the magnetic component 1522 and the elastic component 153 by the guide component 155. Simultaneously, the first sealing component 1521 encloses the outer periphery of the magnetic component 1522, preventing direct contact between the magnetic component 1522 and the atomizing matrix. The magnetic component 1522 can be a magnet with magnetic properties opposite to the magnetic field generated by the induction component 151, allowing them to attract each other and providing power for the movement of the magnetic suction component 152. Under the action of the magnetic field or the elastic component 153, the magnetic suction component 152 moves along the axial direction of the guide component 155 to either a first position or a second position.

[0045] Please refer to Figure 4 The electronic atomizing device 100 also includes a second sealing element 160, which is disposed between the sensing element 151 and the atomizing chamber 120 to seal the atomizing chamber 120. Since the liquid guide tube 140 penetrates the atomizing chamber 120, there is an assembly gap between the liquid guide tube 140 and the bottom wall of the atomizing chamber 120, and there is also an assembly gap at the assembly connection point between the liquid guide tube 140 and the battery valve assembly 150. A portion of the second sealing element 160 is adapted to fit the assembly gaps of the battery valve assembly 150 and the liquid guide tube 140, thereby sealing the gaps between the atomizing chamber 120, the battery valve assembly 150, and the liquid guide tube 140.

[0046] In this embodiment, external gas enters the atomizing chamber 121 from the bottom and then flows from the atomizing chamber 121 to the storage chamber 110 through the liquid guide hole 141. In other embodiments, capillary grooves can be provided on the side wall of the liquid guide tube 140. The capillary grooves allow air to pass through, but the atomizing matrix is ​​difficult to pass through. However, it is difficult to prevent the atomizing matrix from flowing from the capillary grooves toward the sensing element 151 and then leaking through the gap between the liquid guide tube 140 and the second seal 160. Therefore, in this embodiment, the end of the liquid guide tube 140 away from the liquid inlet channel 130 contacts the atomizing chamber 120, and the second seal 160 is set to extend from the position between the sensing element 151 and the atomizing chamber 120 to the space between the liquid guide tube 140 and the atomizing chamber 120, thereby preventing the atomizing matrix from leaking through the gap between the liquid guide tube 140 and the atomizing chamber 120 after flowing down from the capillary grooves.

[0047] Please refer to Figure 3 The electronic atomizing device 100 also includes a liquid reservoir 170 and an atomizing assembly 180. The liquid reservoir 170 is disposed within the atomizing chamber 120 and is used to adsorb the atomizing matrix. The atomizing assembly 180 is disposed within the atomizing cavity 121 and is used to atomize the atomizing matrix. The liquid reservoir 170 is configured to at least partially cover the liquid guiding hole 141 to guide the atomizing matrix to the atomizing assembly 180.

[0048] The liquid reservoir 170 can temporarily store the atomizing matrix flowing from the liquid reservoir 110 into the atomizing chamber 120 to prevent wick clogging. The liquid reservoir 170 is configured to cover the liquid guide hole 141 and the outer wall of the atomizing component 180, thereby limiting the liquid guide path of both to quickly lubricate the atomizing component 180. When the liquid reservoir 170 is saturated, it will slow down or block the liquid guide hole 141, preventing the atomizing matrix in the atomizing chamber 120 from becoming too full.

[0049] Please refer to Figure 3 The electronic atomizing device 100 also includes a third seal 190, which is disposed between the atomizing chamber 120 and the liquid storage chamber 110, forming a liquid inlet channel 130. The liquid guide tube 140 is at least partially housed within the liquid inlet channel 130.

[0050] In one embodiment, the electronic atomizing device 100 further includes a housing 200 and a base 220, the housing 200 being connected to the base 220, an atomizing chamber 120 being disposed within the housing 200, and the atomizing chamber 120 and the inner wall of the housing 200 defining a liquid storage space for storing the atomizing matrix. In this application, a third sealing element 190 is provided to prevent the atomizing matrix in the liquid storage chamber 110 from flowing out through the gap between the atomizing chamber 120 and the inner wall of the housing 200.

[0051] Please refer to Figure 3 The liquid storage chamber 110 has a through-hole forming an air outlet channel 111, one end of which passes through the third seal 190 and communicates with the atomizing assembly 180. In this application, the outer shell 200 is provided with a suction nozzle 210, which communicates with the air outlet channel 111.

[0052] In one embodiment, the air outlet channel 111, the nozzle 210, and the liquid storage tank 110 are integrated into one structure, which can improve the sealing effect of the aerosol conduction path. Furthermore, the end of the air outlet channel 111 facing away from the nozzle 210 passes through the third sealing member 190. While sealing the connection between the liquid storage tank 110 and the atomizing chamber 120, the third sealing member 190 can also seal the connection between the air outlet channel 111 and the atomizing component 180, making the structure of the entire device simpler.

[0053] Please refer to Figure 3 The electronic atomizing device 100 also includes a limiting member 230, which is disposed on the side of the atomizing chamber 120 inside the housing 200 opposite to the liquid storage chamber 110. The electronic atomizing device 100 also includes a power supply 240, and both the body 154 of the solenoid valve assembly 150 and the power supply 240 are limited within the housing 200 by the limiting member 230. More specifically, part of the limiting member 230 is arranged around the periphery of the power supply 240, and the power supply 240 is spaced apart from the body 154.

[0054] The limiting member 230 can fix the relative position of the power supply 240 and the body 154 of the solenoid valve assembly 150, so as to avoid abnormal noise or obstruction of the normal operation of other structures due to the shaking of the power supply 240 and the body 154.

[0055] Please refer to Figure 3-4 The electronic atomizing device 100 also includes a circuit board 250, a vapor adjustment silicone 260, and a vapor adjustment button 270. The vapor adjustment silicone 260 is disposed on a base 220, and the circuit board 250 is disposed on the side of the vapor adjustment silicone 260 away from the base 220. A vapor adjustment channel 261 is provided through the vapor adjustment silicone 260 and the circuit board 250, and one end of the vapor adjustment channel 261 is connected to the atomizing chamber 121. A vapor adjustment opening 221 is provided on the base 220, and the vapor adjustment button 270 is disposed on the vapor adjustment opening 221, which is connected to the vapor adjustment channel 261.

[0056] In this embodiment, by adjusting the air adjustment button 270, outside air can enter the outer casing 200 and flow to the atomizing chamber 121.

[0057] Please refer to Figure 3 The liquid storage tank 110 is provided with a liquid replenishment port 112, which is configured to replenish the atomizing medium to the liquid storage tank 110. The electronic atomizing device 100 also includes a liquid injection plug 113, which is used to seal the liquid replenishment port 112.

[0058] In one embodiment, a replenishment port 112 is provided in the liquid storage tank 110. After the atomizing matrix in the liquid storage tank 110 is consumed, the atomizing matrix can be replenished from the replenishment port 112, so that the electronic atomizing device 100 can be reused or continued to be used, reducing the user's operating costs.

[0059] The injection plug 113, the first seal 1521, the second seal 160, and the third seal 190 can be made of silicone to achieve a sealing effect through interference fit.

[0060] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
