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] To achieve sealed storage during idle periods, some liquid supply devices are equipped with valve-sealing structures at the inlet. These valve-sealing structures are made of elastic materials and can close automatically without external force. However, most existing valve-sealing structures are silicone cross-shaped or star-shaped cut structures with relatively thin walls on the deformable surface, resulting in uncontrollable deformation and the drawback of not being able to completely seal after repositioning. Utility Model Content

[0003] The main objective of this application is to provide a liquid supply device and an electronic atomizer to solve the technical problem that existing valve occlusion structures cannot completely seal after repositioning.

[0004] To achieve the above objectives, the first aspect of this application provides a liquid supply device for use in an atomizing device detachably connected to an electronic atomizer, the atomizing device including a push rod, and the liquid supply device comprising:

[0005] Liquid supply channel, including the liquid supply end; and

[0006] A liquid supply seal is made of an elastic material. The liquid supply seal includes a cylindrical part and a plate part. The cylindrical part is sealed and sleeved to the liquid supply end.

The third sealing plate is further away from the liquid supply end than the sealing step. The third sealing plate has an opening, and the middle part of the third sealing plate is connected to the insert.

[0013] In the closed state, the third sealing piece seals against the sealing step, and the opening is closed by the sealing step; in the liquid inlet state, the push rod passes through the sealing step and connects to the insert, and the third sealing piece deforms away from the sealing step under the action of the insert, and the opening is opened.

[0014] Optionally, the opening is triangular, and there are multiple openings. The periphery of the third sealing piece extends toward the fourth sealing cylinder and is fitted and connected to the outer wall of the fourth sealing cylinder.

[0015] A second aspect of this application provides an electronic atomizer, the electronic atomizer comprising:

[0016] The atomizing device includes the push rod; and

[0017] In any of the above-described liquid supply devices, the push rod is used to push the liquid supply seal away from the liquid supply end through the insert;

[0018] The electronic atomizer includes a detached state and an assembled state; in the detached state, the atomizing device and the liquid supply device are separated from each other, the liquid passage is closed, and the liquid supply seal seals the liquid supply end; in the assembled state, the atomizing device and the liquid supply device are connected to each other; one end of the push rod extending out of the atomizing device is inserted into the insert, the plate portion undergoes elastic deformation in the direction away from the liquid supply end, the liquid passage is opened, and the liquid supply end is connected to the atomizing device.

[0019] Optionally, the atomizing device includes:

[0020] The liquid inlet channel includes a liquid inlet end. One end of the push rod is located inside the liquid inlet channel, and the other end of the push rod extends out of the liquid inlet end. A connecting frame is provided inside the liquid inlet channel. The connecting frame communicates with the liquid inlet channel and connects to the end of the push rod located inside the liquid inlet channel.

[0021] Optionally, the atomizing device includes:

[0022] The liquid inlet seal is made of elastic material and includes a cylindrical body and a sealing plate. The cylindrical body is sleeved outside the liquid inlet end and is arranged in an accordion shape in its axial direction. The sealing plate seals the end of the cylindrical body located outside the liquid inlet end. A slit is provided on the sealing plate. The liquid inlet seal can automatically reset without external force. One end of the push rod extends out of the sealing plate and is sealed to the slit.

[0023] In the disassembled state, the slit is closed and the sealing plate seals the inlet end; in the assembled state, the supply end and / or the supply seal pushes the cylinder near the inlet end to compress the cylinder in its axial direction, the sealing plate is elastically stretched to move with the cylinder, the slit opens, and the inlet end connects to the supply end.

[0024] Optionally, the atomizing device includes:

[0025] Upper shell; and

[0026] A base, together with the upper shell, forms a liquid storage cavity. The liquid inlet channel is formed by the base. The liquid inlet end is the end of the liquid inlet channel away from the liquid storage cavity. A portion of the base extends in a direction away from the liquid storage cavity to form an mounting cylinder. The mounting cylinder is spaced out from the liquid inlet channel. The cylinder body is spaced out between the mounting cylinder and the liquid inlet channel. A portion of the inner wall of the mounting cylinder extends inward to form an annular limiting platform.

[0027] Optionally, one end of the cylindrical portion extends beyond the liquid supply end and is used to abut against the end of the cylindrical body near the liquid inlet end, and the other end of the cylindrical portion is sleeved inside the liquid supply end. In the assembled state, the portion of the sealing plate away from the cylindrical body is located inside the cylindrical portion.

[0028] In the electronic atomizer of this application, the liquid passage of the liquid supply seal can automatically close without external force; therefore, when the liquid supply device is placed alone, it is in an automatically closed state, and the internal atomizing matrix will not leak. When the liquid supply device is assembled with the atomizing device, the push rod pushes the liquid supply seal away from the liquid supply end through the insert, causing the liquid passage to open; thus, the liquid supply device is easy to open during assembly.

[0029] In this application's fluid supply seal, the plate portion has a relatively thick wall, resulting in greater resilience and greater shape stability. The opening of the fluid passage is determined solely by the push rod's stroke; controlling the push rod's advance distance ensures stable triggering of the fluid supply seal's deformation. The insert optimizes the transmission path of the resilience force, achieving precise axial reset and avoiding reset offset caused by the dispersed resilience force in traditional valve occlusion structures. Based on these features, the fluid supply seal's structural deformation is stable, resulting in a better sealing effect after reset. Attached Figure Description

[0048] This application discloses a liquid supply device for connecting to the push rod of an atomizing device. The liquid supply device includes a liquid supply channel and a liquid supply seal. The liquid supply channel includes a liquid supply end. The liquid supply seal is made of an elastic material and includes a cylindrical portion and a plate portion. The cylindrical portion is sealed and fitted to the liquid supply end, and the plate portion is sealed and connected to the inner wall of the cylindrical portion. A liquid passage is formed between the cylindrical portion and the plate portion, or a liquid passage is formed within the plate portion. A sleeve extends from the side of the plate portion facing the liquid supply end toward the liquid supply end, and the sleeve is used to insert into one end of the push rod. The liquid supply seal can automatically reset without external force. The liquid supply device has a closed state and a liquid inlet state. In the closed state, the liquid passage is closed, and the liquid supply seal seals the liquid supply end. In the liquid inlet state, the plate portion undergoes elastic deformation away from the liquid supply end under the push of the push rod through the sleeve, and the liquid passage opens.

[0049] In the electronic atomizer of this application, the liquid passage of the liquid supply seal can automatically close without external force; therefore, when the liquid supply device is placed alone, it is in an automatically closed state, and the internal atomizing matrix will not leak. When the liquid supply device is assembled with the atomizing device, the push rod pushes the liquid supply seal away from the liquid supply end through the insert, causing the liquid passage to open; thus, the liquid supply device is easy to open during assembly. The plate portion of the liquid supply seal has a relatively thick wall, resulting in greater resilience and a more stable shape; the opening of the liquid passage is determined solely by the stroke of the push rod, and by controlling the push rod's advance distance, the deformation of the liquid supply seal can be stably triggered; the insert optimizes the transmission path of the resilience force, and through the precise axial reset of the insert, the reset offset caused by the dispersion of resilience force in traditional valve closure structures can be avoided. Based on the above settings, the structural deformation of the liquid supply seal of this application is stable, resulting in a better sealing effect after reset.

[0050] Please combine Figures 1a to 2h The following will mainly describe the specific structure of the liquid supply device 200.

[0051] The liquid supply device 200 includes a liquid supply channel, which includes a liquid supply end 210. The liquid supply end 210 is opposite to the liquid inlet end 111, that is, the liquid supply end 210 is the end of the liquid supply channel that is away from the inner cavity of the liquid supply device 200.

[0052] The liquid supply device 200 includes a liquid supply seal 220, which is made of an elastic material and can automatically reset without external force. The liquid supply seal 220 is sealed on the liquid supply end 210, and a liquid passage 221 that can be opened and closed is formed on the liquid supply seal 220.

[0053] The fluid supply seal 220 includes a cylindrical portion and a plate portion. The cylindrical portion is sealed and fitted to the fluid supply end 210, and the plate portion is sealed and connected to the inner wall of the cylindrical portion. The plate portion is used to connect one end of the push rod 130. A fluid passage 221 is formed between the cylindrical portion and the plate portion, or the fluid passage 221 is formed within the plate portion. A sleeve 222 extends from the side of the plate portion facing the fluid supply end 210, and the sleeve 222 is used to insert one end of the push rod 130. The fluid supply seal 220 of this application has a relatively large rebound force. The sleeve 222 optimizes the transmission path of the rebound force. Through the precise axial reset of the sleeve 222, the reset offset caused by the dispersion of rebound force in traditional valve occlusion structures can be avoided.

[0054] The liquid supply device 200 has a closed state and a liquid inlet state. In the closed state, the liquid passage 221 is closed, and the liquid supply seal 220 seals the liquid supply end 210. Therefore, when the liquid supply device 200 is placed alone, it is in an automatically closed state, and the internal atomizing matrix will not leak. In the liquid inlet state, the plate portion undergoes elastic deformation away from the liquid supply end 210 under the push of the push rod 130 via the insert 222, and the liquid passage 221 opens. Therefore, when the liquid supply device 200 is assembled with the atomizing device 100, the liquid supply device 200 is easy to open. In the electronic atomizer 10 of this application, the opening of the liquid passage 221 is determined only by the stroke of the push rod 130. As long as the advancing distance of the push rod 130 is controlled, the deformation of the liquid supply seal 220 can be stably triggered.

[0055] Please combine Figures 2a to 2hIn some embodiments, the liquid passage 221 is formed within the sheet portion. The cylindrical portion includes a first sealing cylinder 1a and a second sealing cylinder 1b. The first sealing cylinder 1a is sealed and fitted onto one end of the second sealing cylinder 1b, and the other end of the second sealing cylinder 1b is fitted into the liquid supply end 210. The sheet portion is sealed and connected to the inner wall of the second sealing cylinder 1b and is integrally formed with the second sealing cylinder 1b. The sheet portion includes adjacent first sealing sheets 1c and second sealing sheets 1d. There are multiple first sealing sheets 1c and multiple second sealing sheets 1d arranged around the outer periphery of the insert 222. The multiple first sealing sheets 1c are integrally formed with the insert 222, and the multiple second sealing sheets 1d are movably connected to the insert 222. The liquid passage 221 is formed between adjacent first sealing sheets 1c and second sealing sheets 1d.

[0056] In the closed state of the liquid supply device 200, the first sealing plate 1c and the second sealing plate 1d are in contact with each other, and multiple second sealing plates 1d abut against the insert 222. In the liquid inlet state of the liquid supply device 200, multiple first sealing plates 1c deform away from the liquid supply end 210 under the action of the insert 222, while multiple second sealing plates 1d remain in place, and the gap between the first sealing plates 1c and the second sealing plates 1d opens. The liquid passage 221 is formed within the plate portion. In the closed state, the strong elastic recovery of the plate portion ensures that all parts fit tightly together, eliminating the problem of the liquid passage 221 not closing tightly. When the first sealing plate 1c and the second sealing plate 1d open, the triangular liquid inlet channel 221 between them can effectively prevent the formation of an oil film due to liquid tension, thus ensuring smooth liquid flow.

[0057] The number of first sealing pieces 1c and second sealing pieces 1d is the same, and the number of first sealing pieces 1c and second sealing pieces 1d can be 3 to 5. The second sealing piece 1d can be formed by cutting a piece. Preferably, the number of first sealing pieces 1c and second sealing pieces 1d is 4.

[0058] Please combine Figures 1a to 1eIn other embodiments, a liquid passage 221 is formed between the cylindrical portion and the sheet portion. The cylindrical portion includes a third sealing cylinder 2a and a fourth sealing cylinder 2b. The fourth sealing cylinder 2b is fitted inside the liquid supply end 210, and the third sealing cylinder 2a is fitted between the liquid supply end 210 and the fourth sealing cylinder 2b. The inner wall of the end of the fourth sealing cylinder 2b away from the liquid supply end 210 extends inward to form an annular sealing step 2c. The sealing step 2c may be frustoconical, and the dimension of the sealing step 2c closer to the liquid supply end 210 is smaller. The sheet portion includes a third sealing sheet 2d. The periphery of the third sealing sheet 2d is sealed to the end of the fourth sealing cylinder 2b away from the liquid supply end 210. The third sealing sheet 2d is further away from the liquid supply end 210 than the sealing step 2c. The third sealing sheet 2d and the fourth sealing cylinder 2b may be interlocked, snap-fitted, bonded, or integrally formed. The third sealing plate 2d has multiple openings 2e. The middle part of the third sealing plate 2d is connected to the insert 222, and the third sealing plate 2d and the insert 222 can be integrally formed. The shape of the third sealing plate 2d is adapted to the shape of the sealing step 2c.

[0059] In the closed state of the liquid supply device 200, the third sealing plate 2d protrudes towards the sealing step 2c and seals against the sealing step 2c, while the opening 2e is closed by the sealing step 2c. In the assembled state of the liquid supply device 200, the push rod 130 passes through the sealing step 2c and connects to the insert 222. Under the action of the insert 222, the third sealing plate 2d deforms away from the sealing step 2c, opening the opening 2e. The liquid passage 221 is formed between the cylinder portion and the plate portion. In the closed state, the strong elastic recovery of the plate portion ensures that it fits tightly against the sealing step 2c, eliminating the problem of incomplete closure of the liquid passage 221.

[0060] There can be multiple inlets 2e, for example, 3 to 5. The shape of inlets 2e can be roughly triangular, which can effectively prevent the formation of an oil film due to liquid tension, thus ensuring smoother liquid flow.

[0061] The periphery of the third sealing piece 2d extends toward the fourth sealing cylinder 2b and is fitted and connected to the outer wall of the fourth sealing cylinder 2b (through the fitting of protrusions and grooves). Thus, the connection between the third sealing piece 2d and the fourth sealing cylinder 2b is relatively tight, and the fourth sealing cylinder 2b plays a good limiting role for the third sealing piece 2d, thereby preventing the third sealing piece 2d from moving undesirably.

[0062] Please combine Figures 1a to 2h This application proposes an electronic atomizer 10, which includes an atomizing device 100 and the aforementioned liquid supply device 200.

[0063] The atomizing device 100 is used to atomize an atomizing matrix into an aerosol. The atomizing device 100 includes an upper shell and a base. The base and the upper shell enclose a liquid storage chamber 112. The base has a through-hole liquid inlet channel, which includes an inlet end 111, which is the end of the liquid inlet channel away from the liquid storage chamber 112. A portion of the base extends inward toward the direction away from the liquid storage chamber 112 to form a mounting cylinder 113. The mounting cylinder 113 is spaced outside the liquid inlet channel. A portion of the inner wall of the mounting cylinder 113 extends inward to form an annular limiting platform 114.

[0064] The atomizing device 100 includes the aforementioned push rod 130. One end of the push rod 130 is located within the liquid inlet channel, and the other end extends beyond the liquid inlet end 111. A connecting frame 115 is provided within the liquid inlet channel, communicating with the liquid inlet channel. The inner wall of the liquid inlet channel and the connecting frame 115 can be integrally formed or detachably connected. The connecting frame 115 connects to one end of the push rod 130 located within the liquid inlet channel. The connecting frame 115 and the push rod 130 can be plugged into each other.

[0065] The atomizing device 100 includes a liquid inlet seal 120. The liquid inlet seal 120 is made of an elastic material and can automatically reset without external force.

[0066] Please combine Figures 1a to 1e In some embodiments, the liquid inlet seal 120 includes a cylindrical body 121 and a sealing plate 122, which are integrally formed. The cylindrical body 121 is spaced between the mounting cylinder 113 and the liquid inlet channel, and is fitted outside the liquid inlet end 111. The cylindrical body 121 is arranged in an accordion shape in its axial direction. The sealing plate 122 seals the end of the cylindrical body 121 located outside the liquid inlet end 111, and a slit 123 is provided on the sealing plate 122. There can be multiple slits 123, which are arranged radially. A push rod 130 extends out of the sealing plate 122. A connection port 124 is provided on the sealing plate 122. The connection port 124 is sealed to the push rod 130 in the detached state. The connection port 124 is located at the end where the multiple slits 123 converge, that is, the push rod 130 is sealed to the slits 123.

[0067] The liquid supply end 210 and / or the liquid supply seal 220 are used to push the cylinder 121 away from the liquid inlet end 111 for compression, and the push rod 130 is used to push the liquid supply seal 220 away from the liquid supply end 210 for deformation. The electronic atomizer 10 includes a disassembled state and an assembled state. In the disassembled state of the electronic atomizer 10, the atomizing device 100 and the liquid supply device 200 are separated from each other, the slit 123 is closed, and the sealing plate 122 seals the liquid inlet end 111; the liquid supply device 200 is in a closed state, the liquid passage 221 is closed, and the liquid supply seal 220 seals the liquid supply end 210. In the assembled state of the electronic atomizer 10, the atomizing device 100 and the liquid supply device 200 are connected to each other. The liquid supply end 210 and / or the liquid supply seal 220 push the end of the cylinder 121 close to the liquid inlet end 111 to compress the cylinder 121 in its axial direction. The sealing plate 122 is elastically stretched to move with the cylinder 121, and the slit 123 opens. The liquid supply device is in the liquid inlet state. The push rod 130 extends out of the liquid supply end 210 and pushes the liquid supply seal 220 to make a portion of the liquid supply seal 220 elastically deform in the direction away from the liquid supply end 210. The liquid passage 221 is opened, and the liquid inlet end 111 is connected to the liquid supply end 210.

[0068] In the electronic atomizer 10 of this application, the slit 123 of the sealing plate 122 can automatically close without external force, and the liquid passage 221 of the liquid supply seal 220 can automatically close without external force; thus, when the atomizing device 100 and the liquid supply device 200 are placed separately, the atomizing device 100 and the liquid supply device 200 are in an automatically closed state, and the atomizing matrix inside them will not leak. When the atomizing device 100 and the liquid supply device 200 are assembled, the cylinder 121 is compressed by the push of the liquid supply end 210 and / or the liquid supply seal 220, and the sealing plate 122 is elastically stretched to move with the cylinder 121. The liquid inlet end 111 pushes the slit 123 to open. At the same time, the push rod 130 pushes the liquid supply seal 220 away from the liquid supply end 210 to deform, so that the liquid passage 221 opens, thereby connecting the liquid inlet end 111 to the liquid supply end 210, that is, connecting the atomizing device 100 to the liquid supply device 200. Thus, the automatic liquid flow between the atomizing device 100 and the liquid supply device 200 is realized at the same time as the atomizing device 100 and the liquid supply device 200 are assembled.

[0069] Please combine Figures 1a to 1e In an embodiment where the sealing sheet 122 has multiple radially arranged slits 123, the sealing sheet 122 is fitted into the outer wall of the liquid inlet end 111 in a skirt-like manner in the assembled state.

[0070] In the assembled state of the electronic atomizer 10, the plate portion undergoes elastic deformation in the direction away from the liquid supply end 210. One end of the cylinder portion extends out of the liquid supply end 210 and is used to abut against the end of the cylinder body 121 near the liquid inlet end 111, while the other end of the cylinder portion is sleeved inside the liquid supply end 210. In the assembled state of the electronic atomizer 10, the portion of the sealing plate 122 away from the cylinder body 121 is located inside the cylinder portion.

[0071] Please see Figure 2c and Figure 2d In some embodiments, the atomizing device 100 includes a movable valve ball 116, which is movably disposed within the liquid inlet channel. The movable valve ball 116 is used to move under gravity to open and close the liquid inlet channel. Thus, the liquid supply from the liquid supply device 200 to the atomizing device 100 can be manually controlled, and the gas and liquid within the liquid supply device 200 and the atomizing device 100 cannot flow freely, thereby reducing the risk of leakage in the atomizing device 100. The dimension of the end of the liquid inlet channel near the liquid storage chamber 112 is larger than the dimension of the movable valve ball 116, while the dimension of the liquid inlet end 111 (i.e., the end of the liquid inlet channel away from the liquid storage chamber 112) is smaller than the dimension of the movable valve ball 116. By adjusting the position of the atomizing device 100, when the movable valve ball 116 moves to the end of the liquid inlet channel near the liquid storage chamber 112, the movable valve ball 116 will not close the liquid inlet channel; when the movable valve ball 116 moves to the liquid inlet end 111, the movable valve ball 116 closes the liquid inlet channel.
