Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to a liquid supply device and an electronic atomizer. Background Technology

[0002] In high-capacity electronic atomizers, the liquid supply unit is the core for storing the atomizing matrix. After the supply chamber of the liquid supply unit is connected to the reservoir of the atomizer, the atomizing matrix in the supply chamber is transferred to the reservoir, where it is heated and atomized by the atomizing coil. To achieve sealed storage when not in use, a sealing plug is provided at the supply port of the supply chamber. These sealing plugs are usually independent, separate designs, not fixedly connected to the supply chamber, and are small and flexible.

[0003] When connecting the liquid supply device and the atomizer, the sealing plug on the liquid supply chamber must be removed first. During removal, the small sealing plug easily slips off the fingertip. Furthermore, e-liquid residue often remains around the liquid inlet, and touching it with fingers will leave residue on the atomizer matrix, which is difficult to clean. When the user needs to replace the liquid supply device, the connection between the liquid supply device and the atomizer must be disconnected first. At this time, the liquid inlet of the liquid supply chamber is open, and residual e-liquid can easily drip out. After disconnection, the user needs to find the previously removed sealing plug and reseal the liquid inlet of the liquid supply chamber. However, the sealing plug is small and may have been lost, making resealing the liquid supply chamber inconvenient. Utility Model Content

[0004] The main objective of this application is to provide an electronic atomizer that solves the technical problems of inconvenient opening of the liquid supply device and the need for manual resealing after the liquid supply device and the atomizing device of the electronic atomizer are separated.

[0023] A pusher, one end of which is connected to one of the atomizing plug and the liquid supply plug, and the other end of which is used to abut against the remaining one of the atomizing plug and the liquid supply plug;

[0024] The electronic atomizer has a detached state and an assembled state. In the detached state, the atomizing device and the liquid supply device are detached from each other, and both the liquid inlet slit and the liquid supply slit are closed. In the assembled state, the atomizing device and the liquid supply device are connected to each other. One end of the pusher is connected to the atomizing plug, the liquid inlet slit opens under the cooperation of the pusher and the liquid storage chamber, the other end of the pusher is connected to the liquid supply plug, the liquid supply slit opens under the cooperation of the pusher and the baffle, and the liquid inlet is connected to the liquid supply port.

Compared to the disassembled state, the deformable portion is further closer to the edge of the baffle. The side of the weak portion away from the pusher abuts against the raised portion, and the liquid supply slit is pushed open by the raised portion.

[0027] In the liquid supply device of this application, both ends of the cap sleeve can be detachably connected to the liquid supply chamber. In the stored state of the liquid supply device, one end of the cap sleeve is connected to the liquid supply chamber and covers the liquid supply plug. The cutter is located on the side of the partition away from the liquid supply plug. The cap sleeve protects the liquid supply plug and the liquid supply port. When the liquid supply device is opened, there is no need to remove the liquid supply plug. Simply flip the cap sleeve in the opposite direction, and the cutter on the cap sleeve, with the assistance of the baffle, can cut through the liquid supply plug, forming a liquid supply slit, thus opening the connection between the liquid supply chamber and the outside. The liquid supply plug is made of an elastic material, and the liquid supply slit can automatically close without external force. In other words, the liquid supply plug can automatically reseal the liquid supply chamber without external force. Therefore, when the liquid supply device is placed alone, it is in an automatically sealed state, and the internal atomizing matrix will not leak. Based on the above design, the liquid supply device of this application is easy to open, and no manual sealing is required after the liquid supply device is detached from other components (such as the atomizing device of an electronic atomizer).

[0042] This application discloses a liquid supply device. The liquid supply device includes a liquid supply chamber, a cover cylinder, and a liquid supply plug. The liquid supply chamber has a liquid supply port and includes a baffle that is located inside the liquid supply port and connected to the wall of the liquid supply port. The baffle has a channel for liquid to pass through. Both ends of the cover cylinder can be detachably connected to the liquid supply chamber. A partition is provided in the middle of the cover cylinder, and a cutter is provided on one side of the partition. The liquid supply plug is inserted into the liquid supply port. The cutter is used to cut through the liquid supply plug with the cooperation of the baffle to form a liquid supply slit. The liquid supply plug is made of an elastic material, and the liquid supply slit can close automatically. The liquid supply device has a stored state and an unsealed state. In the stored state, one end of the cover cylinder is connected to the liquid supply chamber and covers the liquid supply plug, and the cutter is located on the side of the partition away from the liquid supply plug. In the unsealed state, the other end of the cover cylinder is connected to the liquid supply chamber and covers the liquid supply plug, and the cutter cuts through the liquid supply plug.

[0043] In the liquid supply device of this application, both ends of the cap sleeve can be detachably connected to the liquid supply chamber. In the stored state of the liquid supply device, one end of the cap sleeve is connected to the liquid supply chamber and covers the liquid supply plug. The cutter is located on the side of the partition away from the liquid supply plug. The cap sleeve protects the liquid supply plug and the liquid supply port. When the liquid supply device is opened, there is no need to remove the liquid supply plug. Simply flip the cap sleeve in the opposite direction, and the cutter on the cap sleeve, with the assistance of the baffle, can cut through the liquid supply plug, forming a liquid supply slit, thus opening the connection between the liquid supply chamber and the outside. The liquid supply plug is made of an elastic material, and the liquid supply slit can automatically close without external force. In other words, the liquid supply plug can automatically reseal the liquid supply chamber without external force. Therefore, when the liquid supply device is placed alone, it is in an automatically sealed state, and the internal atomizing matrix will not leak. Based on the above design, the liquid supply device of this application is easy to open, and no manual sealing is required after the liquid supply device is detached from other components (such as the atomizing device of an electronic atomizer).

[0044] Please combine Figures 1a to 6b The following will mainly describe the specific structure of the liquid supply device 120 of this application.

[0045] The liquid supply device 120 of this application includes a liquid supply chamber 121, which has a liquid supply port 122 and stores a large amount of atomized matrix.

[0046] The liquid supply chamber 121 includes a baffle 126, which is disposed inside the liquid supply port 122 and connected to the wall of the liquid supply port 122. The baffle 126 and the wall of the liquid supply port 122 can be integrally formed. The baffle 126 has a channel for liquid to pass through. The baffle 126 can be generally cross-shaped, radial, grid-shaped, or fence-shaped, etc., without specific limitation.

[0047] The liquid supply device 120 includes a cover cylinder 123, both ends of which are detachably connected to the liquid supply chamber 121 and cover the liquid supply plug 140. The dimensions of both ends of the cover cylinder 123 can be the same. The cover cylinder 123 and the liquid supply chamber 121 can be connected by snap-fit, adhesive, or screw, etc., without specific limitations. A partition 124 is provided in the middle of the cover cylinder 123, and a cutter 125 is provided on one side of the partition 124. The cover cylinder 123, the partition 124, and the cutter 125 can be integrally formed.

[0048] The liquid supply device 120 includes a liquid supply plug 140. The liquid supply plug 140 is plugged into the liquid supply port 122. A cutter 125 is used to cut through the liquid supply plug 140 to form a liquid supply slit 144 in cooperation with a baffle 126. The shape of the cutter 125 is adapted to the shape of the baffle 126, and the cutter 125 may also be generally cross-shaped, radial, grid-shaped, or fence-shaped. The liquid supply plug 140 is made of an elastic material (such as silicone, plastic, and / or rubber), and the liquid supply slit 144 can close automatically. The baffle 126 can limit the liquid supply plug 140, facilitating the cutter 125 to forcefully cut the flexible liquid supply plug 140.

[0049] The liquid supply device 120 has a stored state and an unsealed state. In the stored state, one end of the capping cylinder 123 is connected to the liquid supply chamber 121 and covers the liquid supply plug 140, and the cutter 125 is located on the side of the partition 124 away from the liquid supply plug 140. In the unsealed state, the other end of the capping cylinder 123 is connected to the liquid supply chamber 121 and covers the liquid supply plug 140, and the cutter 125 cuts through the liquid supply plug 140. The stored state and the unsealed state can be switched. Understandably, the liquid supply plug 140 only needs to be cut through once by the cutter 125 to form the liquid supply slit 144. Both ends of the capping cylinder 123 can be switched to be connected to the liquid supply chamber 121. In the stored state, the liquid supply plug 140 may not have been cut through by the cutter 125 or may have already been cut through by the cutter 125.

[0050] In the liquid supply device 120 of this application, both ends of the cover cylinder 123 can be detachably connected to the liquid supply chamber 121. In the stored state of the liquid supply device 120, one end of the cover cylinder 123 is connected to the liquid supply chamber 121 and covers the liquid supply plug 140. The cutter 125 is located on the side of the partition 124 away from the liquid supply plug 140. The cover cylinder 123 can protect the liquid supply plug 140 and the liquid supply port 122. When the liquid supply device 120 is opened, there is no need to remove the liquid supply plug 140. The cover cylinder 123 is flipped in the opposite direction, and the cutter 125 on the cover cylinder 123, with the cooperation of the baffle 126, can cut through the liquid supply plug 140, forming a liquid supply slit 144, thus opening the connection between the liquid supply chamber 121 and the outside. The liquid supply plug 140 is made of elastic material, and the liquid supply slit 144 can automatically close without external force. That is, the liquid supply plug 140 can automatically reseal the liquid supply chamber 121 without external force. Therefore, when the liquid supply device 120 is placed alone, it is in an automatically sealed state, and the atomizing matrix inside will not leak. Based on the above design, the liquid supply device 120 of this application is easy to open, and no manual sealing is required after the liquid supply device 120 is detached from other components (such as the atomizing device of an electronic atomizer).

[0051] In some embodiments, the cutter 125 is completely located within the cover sleeve 123. A raised portion 127 extends from the center of the baffle 126 towards the liquid supply plug 140. The shape of the raised portion 127 is adapted to the shape of the cutter 125, and is generally cross-shaped, radial, grid-shaped, or fence-shaped. The raised portion 127 is used to cooperate with the cutter 125 to cut through the liquid supply plug 140. The arrangement of the cutter 125 being completely located within the cover sleeve 123 prevents injury to the user when the cutter 125 is located on the side of the partition 124 away from the liquid supply plug 140. The side of the raised portion 127 facing the liquid supply plug 140 can be flat, thus providing a larger contact area with the liquid supply plug 140, resulting in better limiting of the liquid supply plug 140 and a better effect of the raised portion 127 cooperating with the cutter 125 to cut through the liquid supply plug 140.

[0052] The cover sleeve 123 includes an auxiliary component 128, which is located on the side of the partition 124 opposite to the cutter 125. The auxiliary component 128 assists in pushing the cutter 125 to cut through the liquid supply plug 140. The auxiliary component 128 can be a protrusion, allowing the user to press the auxiliary component 128 to cut the liquid supply plug 140. The auxiliary component 128 is opposite to the cutter 125, and both can be located in the middle of the partition 124. In the stored state, the auxiliary component 128 is spaced apart from the liquid supply plug 140. Therefore, when the liquid supply device 120 is in the stored state (with the auxiliary component 128 opposite to the liquid supply plug 140) and the liquid supply plug 140 has been cut through by the cutter 125, the auxiliary component 128 will not push open the liquid supply slit 144, thus preventing leakage of the atomized matrix in the liquid supply chamber 121.

[0053] This application discloses an electronic atomizer (not shown). The electronic atomizer includes an atomizing device, a pushing member, and the aforementioned liquid supply device. The atomizing device includes a liquid reservoir and an atomizing plug. The liquid reservoir has a liquid inlet. The atomizing plug is made of an elastic material and is plugged into the liquid inlet. The atomizing plug is detachably connected to the wall of the liquid inlet. One end of the pushing member is connected to one of the liquid reservoir and the liquid supply plug, and the other end of the pushing member is used to abut against the remaining one of the liquid reservoir and the liquid supply plug.

[0054] The electronic atomizer has two states: a detached state and an assembled state. In the detached state, the atomizing device and the liquid supply device are separated, the atomizing plug seals the liquid inlet, and the liquid supply slit is closed. In the assembled state, the atomizing device and the liquid supply device are connected, the atomizing plug is at least partially detached from the liquid inlet, one end of the pusher is connected to the liquid storage tank, and the other end of the pusher is connected to the liquid supply plug. The liquid supply slit opens under the action of the pusher and the baffle, connecting the liquid inlet to the liquid supply port. The rigid restraint of the baffle stabilizes the position of the pusher against the liquid supply plug, thus ensuring a stable open state of the liquid supply slit.

[0055] When assembling the atomizing device and the liquid supply device, first remove the cover from the liquid supply chamber so that the cover does not obstruct the assembly of the atomizing device and the liquid supply device.

[0056] In some embodiments, the pusher is connected to the liquid storage tank and is located at the liquid inlet. Before the atomizing device and the liquid supply device are connected, the atomizing plug is removed from the liquid inlet by the user. When the atomizing device and the liquid supply device are connected, the pusher is limited by the liquid storage tank and pushes the liquid supply plug in the opposite direction toward the baffle. The baffle prevents the liquid supply plug from moving, and the liquid supply plug deforms under the interaction of the pusher and the baffle, opening the liquid supply slit.

[0057] In other embodiments, the pusher is connected to the liquid supply plug, and the pusher and the liquid supply plug can be integrally formed. Before the atomizing device and the liquid supply device are connected to each other, the atomizing plug is removed from the liquid inlet by the user; or, during the connection of the atomizing device and the liquid supply device, the atomizing plug is pushed into the liquid storage tank by the end of the pusher away from the liquid supply plug.

[0058] In an embodiment where the pusher is connected to the liquid supply plug, the liquid storage tank includes a plug block located at the liquid inlet and connected to the wall of the liquid inlet. In the assembled state, the pusher is inserted into the plug block. Thus, the plug block can limit the pusher, thereby controlling the degree of pusher against the liquid supply plug and preventing excessive deformation of the liquid supply plug.

[0059] Please refer to Figure 1 to... Figure 7This application proposes another electronic atomizer 100. The electronic atomizer 100 includes an atomizing device 110, which includes a liquid reservoir 111 with an inlet 112. The atomizing device 110 includes an atomizing plug 130 made of an elastic material (e.g., silicone, plastic, and / or rubber), which plugs into the inlet 112. The atomizing plug 130 has an automatically closing inlet slit 132. The inlet slit 132 of the atomizing plug 130 can automatically close without external force, so when the atomizing device 110 is placed alone, it is in an automatically closed state, and the internal atomizing matrix will not leak.

[0060] The atomizing plug 130 includes an integrally formed cover portion 131 and a connecting cylinder portion 134. One end of the connecting cylinder portion 134 is connected to the cover portion 131, and the connecting cylinder portion 134 is fitted onto the wall of the liquid inlet 112. A liquid inlet slit 132 is formed in the cover portion 131. The connecting cylinder portion 134 and the wall of the liquid inlet 112 can be interference-fitted. The connecting cylinder portion 134 can be generally cylindrical, elliptical, or racetrack-shaped, without specific limitation. The shape of the cover portion 131 is adapted to the shape of the connecting cylinder portion 134, and can be generally circular, elliptical, or racetrack-shaped. The connecting cylinder portion 134 is fixedly connected to the wall of the liquid inlet 112, and the liquid inlet slit 132 can be opened by pushing the cover portion 131 to deform. The cover portion 131 has a certain thickness and can automatically spring back to its original position.

[0061] The electronic atomizer 100 of this application includes a pusher 145. One end of the pusher 145 is connected to one of the atomizing plug 130 and the liquid supply plug 140, and the other end of the pusher 145 is used to abut against the remaining one of the atomizing plug 130 and the liquid supply plug 140.

[0062] The electronic atomizer 100 has a detached state and an assembled state. In the detached state, the atomizing device 110 and the liquid supply device 120 are separated from each other, and both the liquid inlet slit 132 and the liquid supply slit 144 are closed. In the assembled state, the atomizing device 110 and the liquid supply device 120 are connected to each other. One end of the pusher 145 is connected to the atomizing plug 130. The liquid inlet slit 132 is opened by the cooperation of the pusher 145 and the liquid storage chamber 111. The other end of the pusher 145 is connected to the liquid supply plug 140. The liquid supply slit 144 is opened by the cooperation of the pusher 145 and the baffle 126. The liquid inlet 112 is connected to the liquid supply port 122.

[0063] In the electronic atomizer 100 of this application, the liquid inlet slit 132 of the atomizing plug 130 can automatically close without external force, and the liquid supply slit 144 of the liquid supply plug 140 can automatically close without external force. Therefore, when the atomizing device 110 and the liquid supply device 120 are placed separately, the atomizing device 110 and the liquid supply device 120 are in an automatically closed state, and the atomizing matrix inside them will not leak. When the atomizing device 110 and the liquid supply device 120 are assembled, the atomizing plug 130 is deformed by the cooperation of the pushing member 145 and the liquid storage chamber 111, and the liquid inlet slit 132 is opened, forming a channel for liquid to pass through. Simultaneously, the liquid supply plug 140 is deformed by the cooperation of the pushing member 145 and the baffle 126, and the liquid supply slit 144 is opened, forming a channel for liquid to pass through. Because the atomizing plug 130 and the liquid supply plug 140 are elastic, they will generate opposite elastic restoring forces during deformation. This force is balanced with the pushing force of the pushing member 145, which can ensure that the liquid inlet slit 132 and the liquid supply slit 144 are always kept at the ideal opening size, avoiding slit closure or excessive size due to vibration or slight impact.

[0064] In some embodiments, the pusher 145 is connected to the liquid supply plug 140 (the pusher 145 and the liquid supply plug 140 can be integrally formed), and the liquid storage tank 111 includes an insert 113, which is disposed at the liquid inlet 112 and connected to the wall of the liquid inlet 112. The insert 113 and the wall of the liquid inlet 112 can be integrally formed. In the assembled state, the pusher 145 is inserted into the insert 113. Through the rigid limiting of the insert 113, the position of the pusher 145 abutting against the atomizing plug 130 is clearly defined, so that the liquid inlet slit 132 and the liquid supply slit 144 can always be maintained at the ideal opening size.

[0065] The insert 113 is L-shaped, with one end connected to the wall of the liquid inlet 112 and the other end through which the atomizing plug 130 passes. The cover portion 131 has a clearance opening 133 corresponding to the insert 113, and the connecting cylinder portion 134 has a clearance groove 135 corresponding to the insert 113. The side of the atomizing plug 130 facing the inner cavity of the liquid storage tank 111 can abut against the insert 113, or have a relatively small gap from it. Therefore, the L-shaped insert 113 can prevent the connecting cylinder portion 134 from moving towards the inner cavity of the liquid storage tank 111.

[0066] The number of inserts 113 can be at least two, and the at least two inserts 113 are arranged circumferentially along the cover portion 131. The liquid inlet slits 132 are crisscrossed (they can be roughly cross-shaped, grid-shaped, fence-like, or radial), and different parts of the liquid inlet slits 132 can extend to at least two inserts 113 respectively. Thus, the inserts 113 do not significantly obstruct the deformation of the atomizing plug 130 or the opening / closing of the liquid inlet slits 132.

[0067] The pusher 145 is cylindrical and abuts against the cover portion 131. Therefore, the contact surface of the pusher 145 is annular, and the contact area between the pusher 145 and the atomizing plug 130 is relatively large. The annular contact surface can evenly distribute the axial pushing force to the force-bearing surface of the cover portion 131, avoiding uneven deformation of the cover portion 131 caused by local stress concentration. At least two insertion ports 146 are provided at the end of the pusher 145 away from the liquid supply plug 140, corresponding to at least two insertion blocks 113. The at least two insertion blocks 113 form a circumferential limit on the pusher 145, restricting excessive axial displacement of the pusher 145. The force on the pusher 145 is dispersed, and the contact with the atomizing device 110 is stable.

[0068] In an embodiment where the liquid supply device 120 includes a raised portion 127, the liquid supply plug 140 includes a connecting portion 141, a deformable portion 142, and a weak portion 143 that are sequentially fitted from the outside to the inside. The connecting portion 141 is fitted onto the wall of the liquid supply port 122, the liquid supply slit 144 is opened in the weak portion 143, and one end of the pusher 145 is connected between the deformable portion 142 and the weak portion 143. In the disassembled state, the deformable part 142 is suspended between the wall of the liquid supply port 122 and the raised part 127, and the weak part 143 is opposite to and spaced from the raised part 127. In the assembled state, the deformable part 142 is closer to the edge of the baffle 126 than in the disassembled state (the pusher 145 pushes the deformable part 142 toward the edge of the baffle 126), and the side of the weak part 143 away from the pusher 145 abuts against the raised part 127 (the pusher 145 pushes the weak part 143 toward the raised part 127), and the liquid supply slit 144 on the weak part 143 is pushed open by the raised part 127.

[0069] The raised portion 127 can be tapered towards the supply plug 140, thus the transition between the raised portion 127 and the edge of the baffle 126 is smooth, resulting in a smooth deformation transition between the deformable portion 142 and the weak portion 143. This prevents tearing between the deformable portion 142 and the weak portion 143 due to excessive deformation, extending the service life of the supply plug 140. The deformable portion 142 is approximately U-shaped or similar in shape in its cross-section parallel to its direction of movement, such as C-shaped, [-shaped, <-shaped, etc.]. Therefore, the deformable portion 142 has more deformation space, and its movement by the pusher 145 is more effective. In the assembled state, the side of the deformable portion 142 facing away from the pusher 145 abuts against the edge of the baffle 126. Thus, the deformation of the deformable portion 142 is more stable due to the limiting effect of the edge of the baffle 126, thereby making the opening of the supply slit 144 more stable.
