Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to atomization devices and electronic atomizers. Background Technology

[0002] To achieve sealed storage during idle periods, some atomizing devices are equipped with valve-sealing structures at their liquid inlets. 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 surfaces, resulting in uncontrollable deformation and the drawback of incomplete sealing after repositioning. Utility Model Content

[0003] The main purpose of this application is to provide an atomizing 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 an atomizing device, the atomizing device comprising:

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

[0006] 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 and has a slit. The cylindrical body can be compressed away from the liquid inlet end in its axial direction under external force, and the liquid inlet seal can automatically reset when no external force is applied.

[0007] The atomizing device has a closed state and a liquid-inlet state. In the closed state, the cylinder extends naturally, the slit closes, and the sealing plate seals the liquid inlet end. In the liquid-inlet state, the cylinder is compressed axially under external force, the sealing plate is elastically stretched to move with the cylinder, and the slit opens.

[0008] Optionally, there are multiple slits arranged radially, and in the liquid inlet state, the sealing plate is fitted onto the outer wall of the liquid inlet end in a skirt-like shape.

[0009] Optionally, the atomizing device includes:

[0010] upper shell; and

[0011] The 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 the direction away from the liquid storage cavity to form an mounting cylinder. The mounting cylinder is spaced out of 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.

[0012] Optionally, the atomizing device includes:

[0013] A push rod has one end located inside the liquid inlet channel. A connecting frame is provided inside the liquid inlet channel, and the connecting frame connects to the end of the push rod located inside the liquid inlet channel. The other end of the push rod extends out of the liquid inlet end and the sealing plate. A connection port is provided on the sealing plate. The connection port is sealed to the push rod in the closed state and connects to the slit.

[0014] A second aspect of this application provides an electronic atomizer, the electronic atomizer comprising:

[0015] Liquid supply device; and

[0016] The atomizing device described in any of the above embodiments, wherein the atomizing device is detachably connected to the liquid supply device, and the liquid supply device is used to push the cylinder away from the liquid inlet end along its axial direction to compress it.

[0017] A second aspect of this application provides for another electronic atomizer, said electronic atomizer comprising:

[0018] Liquid supply device; and

[0019] The atomizing device described in any of the above embodiments, wherein the atomizing device is detachably connected to the liquid supply device, the liquid supply device is used to push the cylinder away from the liquid inlet end along its axial direction to compress it, and the push rod is used to open the connection between the liquid supply device and the atomizing device.

[0020] The liquid supply device includes:

[0021] A liquid supply channel includes a liquid supply end, which is opposite to the liquid inlet end; and

[0022] The liquid supply seal is made of an elastic material and is sealed on the liquid supply end. The liquid supply seal has a liquid passage that can be opened and closed. The liquid supply end and / or the liquid supply seal are used to push the cylinder away from the liquid inlet end for compression. The push rod is used to push the liquid supply seal away from the liquid supply end for deformation.

[0023] The electronic atomizer has 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 slit is closed, the sealing plate seals the liquid inlet end, the liquid passage is closed, and the liquid supply seal seals the liquid supply end;

[0024] In the assembled state, the atomizing device and the liquid supply device are connected to each other. The liquid supply end and / or the liquid supply seal pushes against the end of the cylinder near the liquid inlet end to compress the cylinder in its axial direction. The sealing plate is elastically stretched to move with the cylinder, and the slit opens. The end of the push rod extending from the liquid supply end pushes against the liquid supply seal to cause a portion of the liquid supply seal to elastically deform in the direction away from the liquid supply end. The liquid passage opens, and the liquid inlet end connects to the liquid supply end.

[0025] Optionally, the liquid supply seal includes a cylindrical portion and a plate portion. The cylindrical portion is sealed to the liquid supply end, and the plate portion is sealed to the inner wall of the cylindrical portion. The plate portion is used to connect one end of the push rod that extends out of the sealing plate. The liquid passage is formed between the cylindrical portion and the plate portion, or the liquid passage is formed within the plate portion. In the assembled state, the plate portion undergoes elastic deformation in a direction away from the liquid supply end.

[0026] 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.

[0027] Optionally, the side of the plate facing the liquid supply end extends toward the liquid supply end to form a plug, which is used to insert the push rod extending out of the closed plate.

[0028] In the atomizing device of this application, the cylinder naturally extends under no external force, and the slit of the sealing plate automatically closes. Therefore, when the atomizing device is placed alone, it is in an automatically sealed state, preventing leakage of the internal atomizing matrix. When the atomizing device and the liquid supply device of the electronic atomizer are assembled, the cylinder is compressed by the liquid supply device, and the sealing plate elastically stretches to move with the cylinder, causing the liquid inlet end to push the slit open. Thus, the atomizing device is easy to open when assembled with the liquid supply device. In the liquid inlet seal of the atomizing device, the pleated structure of the accordion-shaped cylinder has directional reset memory. When compressed and released, the pleats automatically extend axially, causing the sealing plate to precisely fit the liquid inlet end, avoiding the valve leaf displacement and micro-opening caused by the lack of directional constraint in traditional valve sealing structures. This ensures a stable sealing effect after the liquid inlet seal is reset. Attached Figure Description

[0048] This application discloses an atomizing device, which includes a liquid inlet end and a liquid inlet seal. The liquid inlet seal is made of an elastic material and includes a cylinder and a sealing plate. The cylinder 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 cylinder located outside the liquid inlet end and has a slit. The cylinder can be compressed away from the liquid inlet end in its axial direction under external force, and the liquid inlet seal can automatically reset without external force. The atomizing device has a closed state and a liquid inlet state. In the closed state of the atomizing device, the cylinder naturally extends, the slit closes, and the sealing plate seals the liquid inlet end. In the liquid inlet state of the atomizing device, the cylinder is compressed in its axial direction under external force, the sealing plate is elastically stretched to move with the cylinder, and the slit opens.

[0049] In the atomizing device of this application, the cylinder naturally extends under no external force, and the slit of the sealing plate automatically closes. Therefore, when the atomizing device is placed alone, it is in an automatically sealed state, preventing leakage of the internal atomizing matrix. When the atomizing device and the liquid supply device of the electronic atomizer are assembled, the cylinder is compressed by the liquid supply device, and the sealing plate elastically stretches to move with the cylinder, causing the liquid inlet end to push the slit open. Thus, the atomizing device is easy to open when assembled with the liquid supply device. In the liquid inlet seal of the atomizing device, the pleated structure of the accordion-shaped cylinder has directional reset memory. When compressed and released, the pleats automatically extend axially, causing the sealing plate to precisely fit the liquid inlet end, avoiding the valve leaf displacement and micro-opening caused by the lack of directional constraint in traditional valve sealing structures. This ensures a stable sealing effect after the liquid inlet seal is reset.

[0050] Please see Figures 1a to 2h The following will mainly describe the specific structure of the atomizing device 100.

[0051] The atomizing device 100 of this application 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 cavity 112. The base has a liquid inlet channel, which includes an inlet end 111, which is the end of the liquid inlet channel away from the liquid storage cavity 112. A portion of the base extends in the direction away from the liquid storage cavity 112 to form an 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.

[0052] 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.

[0053] 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 formed on the sealing plate 122. There can be multiple slits 123, which are arranged radially.

[0054] The atomizing device 100 has a closed state and a liquid-inlet state. In the closed state, the cylinder 121 extends naturally, the slit 123 closes, and the sealing plate 122 seals the liquid inlet end 111. Thus, when the atomizing device 100 is placed alone, it is in an automatically closed state, and the atomizing matrix inside will not leak. In the liquid-inlet state, the cylinder 121 is compressed in its axial direction (i.e., the direction of extension of the liquid inlet channel) under external force, the sealing plate 122 is elastically stretched to move with the cylinder 121, and the slit 123 opens. Thus, the atomizing device 100 is easy to open when assembled. In the atomizing device 100 of this application, the pleated structure of the accordion-shaped cylinder 121 has directional reset memory. When it is compressed and then released, the pleats will automatically extend along the axial direction, causing the sealing plate 122 to precisely fit the liquid inlet end 111. This avoids the valve leaf displacement and micro-opening caused by the lack of directional constraint in the traditional valve sealing structure, so that the sealing effect of the liquid inlet seal 120 after reset is stable.

[0055] Please combine Figures 1a to 1e In some embodiments, the atomizing device 100 includes a push rod 130, one end of which is located within the liquid inlet channel, and the other end extends beyond the liquid inlet end 111 and the sealing plate 122. The sealing plate 122 has a connection port 124, which is sealed to the push rod 130. The connection port 124 is located at one end where multiple slits 123 converge, meaning the push rod 130 is sealed to the slits 123. 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.

[0056] 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 likelihood 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.

[0057] Please see Figures 1a to 2h This application discloses an electronic atomizer 100. The electronic atomizer 100 includes a liquid supply device 200 and the aforementioned atomizing device 100. The liquid supply device 200 stores a large amount of atomizing matrix and supplies liquid to the atomizing device 100. The liquid supply device 200 is detachably connected to the atomizing device 100. The liquid supply device 200 is used to push the cylinder 121 axially away from the liquid inlet end 111 for compression. In an embodiment where the atomizing device 100 includes a push rod 130, the push rod 130 is used to open the communication between the liquid supply device 200 and the atomizing device 100. The liquid supply device 200 includes a liquid supply channel, which includes a liquid supply end 210 opposite to the liquid inlet end 111; that is, the liquid supply end 210 is the end of the liquid supply channel away from the inner cavity of the liquid supply device 200.

[0058] 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.

[0059] 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 atomizing device 100 is in a closed state, the slit 123 is closed, the sealing plate 122 seals the liquid inlet end 111; 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 atomizing device 100 is in the liquid inlet state. The liquid supply end 210 and / or the liquid supply seal 220 push the end of the cylinder 121 near 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 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.

[0060] 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. The sealing plate 122 is elastically stretched to move with the cylinder 121, and 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, thereby opening the liquid passage 221. Thus, the liquid inlet end 111 is connected to the liquid supply end 210, that is, the atomizing device 100 is connected to the liquid supply device 200. Therefore, when the atomizing device 100 and the liquid supply device 200 are assembled, automatic liquid flow between the two can be achieved. 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 pushing distance of the push rod 130 is controlled, the deformation of the liquid supply seal 220 can be stably triggered.

[0061] 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.

[0062] The liquid supply seal 220 includes a cylindrical portion and a plate portion. The cylindrical portion is sealed and fitted onto the liquid 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 extending out of the sealing plate 122. A liquid passage 221 is formed between the cylindrical portion and the plate portion, or the liquid passage 221 is formed within the plate portion. In the assembled state, the plate portion undergoes elastic deformation in the direction away from the liquid supply end 210. One end of the cylindrical portion extends out of the liquid supply end 210 and is used to abut against the end of the cylindrical body 121 near the liquid inlet end 111. The other end of the cylindrical portion is fitted into the liquid supply end 210. In the assembled state, the portion of the sealing plate 122 away from the cylindrical body 121 is located within the cylindrical portion. A insert 222 extends from the side of the plate portion facing the liquid supply end 210 towards the liquid supply end 210. The insert 222 is used to insert the end of the push rod 130 extending out of the sealing plate 122. The fluid supply seal 220 of this application has a relatively large rebound force. The insert 222 optimizes the transmission path of the rebound force. Through the axial precise reset of the insert 222, the reset offset caused by the dispersion of rebound force in the traditional valve occlusion structure can be avoided.

[0063] 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.

[0064] In the detached state of the electronic atomizer 10, the first sealing plate 1c and the second sealing plate 1d are correspondingly attached, and multiple second sealing plates 1d abut against the insert 222. In the assembled state of the electronic atomizer 10, 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. In this embodiment, the plate portion closes the liquid passage 221 through its own strong elastic retraction, eliminating the problem of incomplete closure of the liquid passage 221. Furthermore, when the first sealing plate 1c and the second sealing plate 1d are open, the triangular liquid inlet channel 221 between them can effectively prevent the formation of an oil film due to liquid tension, thus ensuring smoother liquid flow.

[0065] Please combine Figures 1a to 1e In some 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 size of the end 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 connected by snap-fit, snap-fit, adhesive, 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.

[0066] In the detached state of the atomizer 10, the third sealing plate 2d protrudes towards the sealing step 2c and seals against it, while the opening 2e is closed by the sealing step 2c. In the assembled state of the atomizer 10, the push rod 130 passes through the sealing step 2c and connects to the insert 222. Under the influence of the insert 222, the third sealing plate 2d deforms away from the sealing step 2c, opening the opening 2e. In this embodiment, the strong elastic recovery of the plate portion in the closed state ensures a tight fit against the sealing step 2c, thus preventing the liquid passage 221 from not closing properly. The number of openings 2e can be multiple, for example, 3 to 5. The shape of the openings 2e can be approximately triangular, which effectively avoids the formation of an oil film due to liquid tension, resulting in smoother liquid flow.

[0067] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
