Description

Technical Field

[0001] This invention relates to an atomizing heating device. Background Technology

[0002] Existing atomizing heating devices store liquid oil in an oil reservoir, and then heat and atomize the stored oil using an atomizing component installed within the reservoir to generate an aerosol. However, existing oil reservoirs typically have a fixed capacity, preventing users from adjusting it to their specific needs. To meet the varying requirements of different users for reservoir capacity, atomizing heating devices need to be equipped with oil tanks of different capacities. However, existing oil tanks of different capacities are often incompatible with the same controller, causing inconvenience for users.

[0003] Therefore, existing technologies still need to be improved and enhanced. Summary of the Invention

[0004] The main objective of this invention is to provide an atomizing heating device that allows users to flexibly adjust the capacity of the oil storage chamber.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] An atomizing heating device, comprising:

[0007] The housing has a receiving groove;

[0008] A suction nozzle assembly is rotatably mounted on the opening of the receiving groove and closes the opening, with one end of the suction nozzle assembly extending into the receiving groove and the other end extending out of the housing;

[0009] An atomizing component is housed within the receiving groove, with one end connected to the mouthpiece assembly and the other end inserted into the bottom wall of the receiving groove to form an atomizing channel penetrating the receiving groove.

[0010] An adjustment component, one end of which is threadedly connected to the portion of the nozzle assembly that extends into the receiving groove, and the other end which is movably clamped between the side wall of the receiving groove and the side wall of the atomizing assembly, so as to form a sealed oil storage chamber with the bottom wall of the receiving groove.

[0011] When the nozzle assembly is rotated, the adjustment assembly moves along the axial direction of the atomizing assembly under the drive of the nozzle assembly to adjust the volume of the oil storage chamber.

[0012] The atomizing heating device includes an adjusting component comprising a lifting plate and a movable rod extending vertically from the lifting plate. The lifting plate is sleeved on the outer periphery of the atomizing component and can only move along the axial direction of the atomizing component. The outer periphery of the lifting plate elastically abuts against the side wall of the receiving groove. The movable rod is threadedly connected to the portion of the nozzle assembly that extends into the receiving groove. When the nozzle assembly is rotated, the movable rod engages with the nozzle assembly threadedly and drives the lifting plate to move along the axial direction of the atomizing component.

[0013] In the atomizing heating device, the outer periphery of the movable rod is provided with an external thread, the nozzle assembly is provided with a threaded hole adapted to the movable rod, and the movable rod is threadedly connected to the threaded hole via the external thread.

[0014] The atomizing heating device includes a movable rod coaxially arranged with the nozzle assembly and a clearance hole coaxial with the atomizing assembly. The atomizing assembly passes through the clearance hole and connects with the nozzle assembly.

[0015] The atomizing heating device includes a notch on the outer periphery of the lifting plate and a corresponding protrusion extending in the axial direction on the side wall of the receiving groove. When the lifting plate is placed in the receiving groove, the notch fits into the corresponding protrusion so that the lifting plate can only move along the extension direction of the protrusion.

[0016] The atomizing heating device includes a lifting plate comprising an annular lifting plate body, a first sealing element being fastened to the outer side wall of the lifting plate body, and a second sealing element being fastened to the inner side wall of the lifting plate body. The first sealing element elastically abuts against the side wall of the receiving groove, and the second sealing element elastically abuts against the outer periphery of the atomizing component.

[0017] The atomizing heating device includes a first annular receiving groove on the outer side wall of the lifting plate body that is adapted to the first sealing member, and a second annular receiving groove on the inner side wall that is adapted to the second sealing member. The first sealing member and the second sealing member are respectively installed in the corresponding annular receiving grooves.

[0018] The atomizing heating device includes a nozzle assembly comprising a cover adapted to the opening of the receiving groove, an air outlet pipe passing through the cover, and a connecting pipe with a threaded hole. The cover is rotatably closed to the opening of the receiving groove. The connecting pipe is housed in the receiving groove, with one end fixedly connected to the cover and the other end threadedly connected to the adjusting assembly via the threaded hole.

[0019] In the atomizing heating device, a first limiting member protrudes from the edge of the cover towards the receiving groove, and a second limiting member adapted to the first limiting member is provided on the side wall of the receiving groove near the opening. The first limiting member is connected to the second limiting member and can rotate relative to the second limiting member.

[0020] In the atomizing heating device, the adjusting member protrudes a limiting post toward the bottom wall of the receiving groove, and the housing is provided with an oil injection hole that communicates with the receiving groove. When the adjusting member moves to the point where the limiting post abuts against the bottom wall of the receiving groove, the oil injection hole communicates with the oil storage chamber.

[0021] The atomizing heating device further includes at least one oil storage bottle, and the bottom wall of the receiving groove has at least one oil passage component that communicates with the oil storage cavity. The oil storage bottle is detachably installed on the oil passage component.

[0022] The atomizing heating device includes an oil passage component comprising an oil passage pipe and an installation pipe. The oil passage pipe passes through the bottom wall of the receiving groove and extends out of the housing at one end. The installation pipe is arranged around the oil passage pipe and is fixedly connected to the housing at one end. The other end of the pipe wall is provided with a connection part adapted to the oil storage bottle. When the oil storage bottle is detachably connected to the connection part, the oil storage bottle is connected to the oil passage pipe.

[0023] The atomizing heating device includes a connecting part comprising at least one elastic buckle, and the neck of the oil storage bottle is provided with a matching annular groove. When at least one of the elastic buckles is engaged in the annular groove, the oil storage bottle is detachably installed on the oil passage component.

[0024] In the atomizing heating device, an oil valve is provided at one end of the oil storage bottle near the bottle opening. When the oil storage bottle is detachably connected to the oil passage component, the oil passage component extends into the oil storage bottle and opens the oil valve to connect the oil storage bottle. When the oil storage bottle is de-detached from the oil passage component, the oil passage component disengages from the oil storage bottle, and the oil valve closes to seal the oil storage bottle.

[0025] The atomizing heating device includes an oil valve comprising a fixing sleeve and an elastic diaphragm having at least one opening. The fixing sleeve is fitted onto the mouth of the oil storage bottle and partially covers the inner wall of the oil storage bottle and partially covers the outer periphery of the oil storage bottle. The edge of the elastic diaphragm is connected to the portion of the fixing sleeve covering the inner wall of the oil storage bottle to close the oil storage bottle. When the oil storage bottle is installed on the oil inlet, the oil inlet extends into the oil storage bottle and pushes open the opening to open the oil valve.

[0026] The atomizing heating device further includes an oil-proof plug adapted to the oil passage component. When the oil storage bottle is detached from the oil passage component, the oil-proof plug is installed on the oil passage component to seal the oil storage chamber.

[0027] Beneficial Effects: This invention provides an atomizing heating device, including a housing, a nozzle assembly, an atomizing assembly, and an adjusting assembly. The housing has a receiving groove. The nozzle assembly is rotatably mounted on the open end of the receiving groove, with one end extending into the receiving groove and the other end extending out of the housing for user inhalation. The atomizing assembly is housed within the receiving groove, with one end connected to the nozzle assembly and the other end inserted into the bottom wall of the receiving groove, forming an atomizing channel penetrating the receiving groove. One end of the adjusting assembly is threadedly connected to the portion of the nozzle assembly that extends into the receiving groove, and the other end is movably clamped between the side wall of the mounting groove and the side wall of the atomizing assembly, forming a sealed oil storage chamber with the bottom wall of the mounting groove. When the nozzle assembly is rotated, the adjusting assembly moves along the axial direction of the atomizing assembly under the drive of the nozzle assembly, thereby adjusting the volume of the oil storage chamber. By rotating the suction nozzle assembly to engage with the threaded adjustment assembly, the position of the adjustment assembly can be adjusted, thereby adjusting the volume of the oil storage chamber and allowing for flexible adjustment of the oil storage amount.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0041] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0043] Please refer to Figures 1-9 This invention proposes an atomizing heating device, comprising a housing 1, a mouthpiece assembly 2, an atomizing assembly 3, and an adjusting assembly 4. The housing 1 has a receiving groove 13. The mouthpiece assembly 2 is rotatably mounted on the open end of the receiving groove 13 and closes the opening. One end of the mouthpiece assembly 2 extends into the receiving groove 13, and the other end extends out of the housing 1 for user inhalation. The atomizing assembly 3 is housed within the receiving groove 13, with one end connected to the mouthpiece assembly 2 and the other end inserted into the bottom wall of the receiving groove 13, forming an atomizing channel 31 penetrating the receiving groove 13. One end of the adjusting assembly 4 is threadedly connected to the portion of the mouthpiece assembly 2 that extends into the receiving groove 13, and the other end is movably clamped between the side wall of the receiving groove 13 and the side wall of the atomizing assembly 3, forming a sealed oil storage cavity 14 with the bottom wall of the receiving groove 13. When the nozzle assembly 2 is rotated, the adjusting assembly 4 moves along the axial direction of the atomizing assembly 3 under the drive of the nozzle assembly 2, thereby adjusting the volume of the oil storage chamber 14. By rotating the nozzle assembly 2 to make it threadedly engage with the adjusting assembly 4, the position of the adjusting assembly 4 is adjusted, thereby achieving the purpose of adjusting the volume of the oil storage chamber 14, so that the capacity of the oil storage chamber 14 can be flexibly adjusted.

[0044] In some embodiments, such as Figure 1 and Figure 2As shown, the housing 1 includes a sleeve 11 and a base 12. The sleeve 11 has a hollow cylindrical structure, and the base 12 is installed at one end of the sleeve 11 and seals the opening at one end of the sleeve 11, thereby forming the receiving groove 13 with the sleeve 11. The open end of the receiving groove 13 is opposite to the base 12, that is, the base 12 forms the bottom wall of the receiving groove 13, and the inner wall of the sleeve 11 forms the side wall of the receiving groove 13. In practical applications, the base 12 includes a bottom cover 121 and a sealing seat 122. The bottom cover 121 is fastened to one end of the sleeve 11 and closes the opening at one end. At least one buckle can be provided circumferentially on the bottom cover 121, and at least one corresponding locking hole can be provided on the side wall of the sleeve 11. The bottom cover 121 is fastened to the sleeve 11 by the cooperation between the buckle and the locking hole. The bottom cover 121 is partially housed within the housing 11 and has an annular buckle 1211 protruding axially. The annular buckle 1211 and the side wall of the housing 11 form an annular limiting groove. The sealing seat 122 covers the side of the bottom cover 121 housed within the housing 11 and has an annular groove (not shown in the diagram) that matches the annular buckle 1211. The annular buckle 1211 extends into the annular groove, so that the portion of the sealing seat 122 near its outer periphery is clamped between the bottom cover 121 and the housing 11. This not only secures the sealing seat 122 inward to prevent it from detaching from the bottom cover 121, but also seals the gap between the bottom cover 121 and the housing 11, forming a sealed oil storage cavity 14. That is, the side of the sealing seat 122 facing away from the bottom cover 121 forms the bottom wall of the oil storage cavity 14.

[0045] In some embodiments, please refer to Figure 2 and Figure 3The suction nozzle assembly 2 includes a cover 21, an air outlet pipe 22, and a connecting pipe 23. The cover 21 is adapted to the opening of the receiving groove 13 and is rotatably mounted on the housing 11. The air outlet pipe 22 passes through the cover 21, with one end extending into the receiving groove 13 and the other end extending out of the cover 21 for the user to inhale. A first limiting member 211 protrudes from the cover 21 toward the receiving groove 13. Correspondingly, the inner wall of the housing 11 is provided with a matching second limiting member 111. The first limiting member 211 is connected to the second limiting member 111 and can rotate relative to the second limiting member 111. In practical applications, the first limiting member 211 can be a ring-shaped sliding buckle, and the second limiting member 111 can be a matching ring-shaped protruding buckle. The annular sliding buckle includes an elastic arm connected to the cover 21 and a latching part connected to the elastic arm. When the cover 21 is installed, the latching part first extends into the receiving groove 13 and engages with the annular protrusion. Under the action of the annular protrusion, the elastic arm undergoes elastic deformation and drives the latching part to engage with the annular protrusion. The annular sliding buckle can slide relative to the annular protrusion. In this embodiment, the use of an elastic annular sliding buckle not only makes it less prone to damage during installation, but also ensures that the cooperation between the annular sliding buckle and the annular protrusion prevents the cover 21 from detaching from the housing 1 when it is rotated.

[0046] In some embodiments, such as Figure 3As shown, the atomizing assembly 3 includes an atomizing tube with an oil passage, an oil guide, and a heating element. The oil guide covers the heating element to form an atomizing core, which is housed within the atomizing tube and has a through hole coaxial with the atomizing tube. In practical applications, the atomizing assembly 3 may also include an oil suction element located between the atomizing core and the atomizing tube. The oil suction element absorbs oil from the oil storage chamber 14 through the oil passage, and then the oil guide absorbs the oil stored by the oil suction element. This makes the oil absorption more uniform and reduces the generation of condensate. One end of the atomizing tube is inserted into the base 12, and the other end is connected to the air outlet 22 to form an atomizing channel 31 that penetrates the receiving groove 13. Correspondingly, the base 12 is provided with a insertion hole adapted to the atomizing assembly 3, that is, the bottom cover 121 and the sealing seat 122 are provided with coaxial clearance holes to form the insertion hole. The atomizing component 3 is sequentially and securely inserted into the two clearance holes, thereby securing it to the base 12. In practical applications, the atomizing component 3 can penetrate the base 12, eliminating the need for an additional air inlet on the base 12, allowing outside air to directly enter the atomizing channel from one end of the atomizing tube. Preferably, the atomizing component 3 does not penetrate the base 12, i.e., the insertion hole does not penetrate the base 12. A liquid storage tank can also be provided around the insertion hole on the base 12, allowing the condensate flowing from the atomizing component 3 to be stored in the tank without leakage. Furthermore, at least one air inlet 1212 can be added to the base 12, offset from the atomizing component 3, thus not affecting air intake and preventing condensate from flowing directly out of the air inlet 1212. Outside air enters the atomization channel through the air inlet 1212, and the aerosol generated by atomization flows from the atomization tube into the air outlet 22 and then flows out from the air outlet 22.

[0047] In some embodiments, please refer to Figures 2-6The adjusting assembly 4 includes a lifting plate 41 and a movable rod 42. The lifting plate 41 includes a roughly annular lifting plate body 411. The outer circumferential shape of the lifting plate body 411 is adapted to the cross-section of the receiving groove 13, and the inner circumferential shape and size of the lifting plate 41 are adapted to the atomizing assembly 3. The inner sidewall of the lifting plate body 411 is slidably sleeved on the outer circumference of the atomizing tube, and the outer sidewall elastically abuts against the sidewall of the receiving groove 13. In practical applications, a first sealing member 412 is tightly sleeved on the outer sidewall of the lifting plate body 411, and a second sealing member 413 is tightly sleeved on the inner sidewall of the lifting plate body 411. When the lifting plate body 411 is sleeved on the outer circumference of the atomizing assembly 3 and accommodated in the receiving groove 13, the first sealing member 412 elastically abuts against the sidewall of the receiving groove 13, and the second sealing member 413 elastically abuts against the outer circumference of the atomizing assembly 3. The lifting plate 41 and the side wall of the receiving groove 13, as well as the installation gap between the lifting plate 41 and the atomizing component 3, are sealed by two seals. Preferably, a first annular mounting groove 4111 adapted to the first seal 412 is provided on the outer side wall of the lifting plate body 411, and a second annular groove (not shown in the figure) adapted to the second seal 413 is provided on the inner side wall. The first seal 412 is installed in the first annular mounting groove 4111, and the second seal 413 is installed in the second annular receiving groove 13. The two annular receiving grooves 13 respectively limit the two seals to prevent the seals from falling off during the movement of the lifting plate 41. Of course, the first seal and the second seal can also cover the outer side wall and the inner side wall of the lifting plate body 411, respectively. Alternatively, the lifting plate body 411 and the two seals can be made into an integral structure, for example, by integrally molding the lifting plate 41 into a flexible and rigid integral structure. In this way, there is no risk of the seals falling off, and the installation process of the seals is eliminated. When the lifting plate 41 is installed in the receiving groove 13, the lifting plate 41, the casing 11, the atomizing tube, and the base 12 form a sealed and variable-volume oil storage chamber 14. That is, the lifting plate 41 forms the top wall of the oil storage chamber 14, the outer periphery of the atomizing tube and the inner wall of the casing 11 form the side walls of the oil storage chamber 14, and the base 12 forms the bottom wall of the oil storage chamber 14. When the lifting plate 41 moves up and down under the action of the movable rod 42, the distance between the top wall and the bottom wall of the oil storage chamber 14 changes, thereby changing the volume of the oil storage chamber 14.

[0048] In some embodiments, such as Figure 5As shown, the outer periphery of the lifting plate 41 is provided with at least one notch 414, and the side wall of the receiving groove 13 is provided with at least one protrusion 112. The protrusion 112 extends along the axial direction of the atomizing component 3, that is, along a direction perpendicular to the lifting plate 41. When the lifting plate 41 is accommodated in the receiving groove 13, the notch 414 fits into the corresponding protrusion 112. In practical applications, there can be one, two, or more notches 414, and one, two, or more protrusions 112 are correspondingly provided. The shape of the notch 414 can be a plane, an inclined surface, or a curved surface, and there is no limitation here. Only when the notch 414 fits into the corresponding protrusion 112 can the lifting plate 41 be installed into the receiving groove 13. The lifting plate 41 is positioned and limited by the cooperation between the notch 414 and the protrusion 112. Since the protrusion 112 extends along the axial direction of the atomizing component 3, the notch 414 can only slide along the extending direction of the protrusion 112. Therefore, under the restriction of the protrusion 112, the lifting plate 41 can only slide along the extending direction of the protrusion 112. It is worth noting that in practical applications, other foolproof structures can also be used to limit the lifting plate 41, which are not limited here.

[0049] Please refer to Figure 3 and Figure 4 One end of the movable rod 42 is threadedly connected to the nozzle assembly 2, and the other end is fixedly connected to the lifting plate 41. The outer circumference of the movable rod 42 is provided with an external thread 421. Correspondingly, a connecting tube 23 protrudes from the cover 21 towards the receiving groove 13, and the inner wall of the connecting tube 23 is provided with a threaded hole 231 adapted to the external thread 421. The threaded connection between the threaded hole 231 and the external thread 421 enables meshing and transmission. When the nozzle assembly 2 is rotated under force, the threaded hole 231 on the connecting tube 23 rotates and meshes with the external thread 421 on the movable rod 42. Since the movable rod 42 is fixedly connected to the lifting plate 41, and the lifting plate 41 cannot rotate under the restriction of the protrusion 112, the movable rod 42 also cannot rotate. Therefore, the threaded meshing transmission between the connecting tube 23 and the movable rod 42 converts the rotational motion of the nozzle into axial motion, thereby enabling the movable rod 42 and the lifting plate 41 to move along the axial direction of the connecting tube 23. Since the lifting plate 41 is equivalent to the top wall of the oil storage chamber 14, the size of the oil storage chamber 14 can be adjusted by moving the top wall of the oil storage chamber 14 up and down, so that the user can flexibly adjust the oil storage volume according to the needs.

[0050] Preferably, the movable rod 42 is coaxial with the nozzle assembly 2, and correspondingly, the connecting pipe 23 is coaxial with the movable rod 42 and the cover 21. The movable rod 42 has a clearance hole 422 coaxial with the atomizing component 3. The atomizing component 3 passes through the clearance hole 422 and connects to the air outlet pipe 22. Therefore, in this embodiment, the movable rod 42, connecting pipe 23, air outlet pipe 22, atomizing component 3, and cover 21 are all coaxially arranged. When the nozzle assembly 2 is rotated under force, the connecting pipe 23 rotates coaxially with the nozzle, and the external thread 421 on the movable rod 42 and the internal thread on the connecting pipe 23 form a threaded engagement, causing the movable rod 42 to move up and down along the axial direction of the connecting pipe 23, and driving the lifting plate 41 to move up and down along the axial direction of the connecting pipe 23. In this embodiment, the coaxial arrangement of the connecting pipe 23 and the nozzle facilitates the formation of a stable and reliable threaded engagement between the connecting pipe 23 and the movable rod 42.

[0051] In some embodiments, please refer to Figure 6 The adjusting component 4 has a limiting post 43 protruding from the bottom wall of the receiving groove 13. That is, the limiting post 43 is connected to the side of the lifting plate 41 away from the movable rod 42 and is located in the oil storage cavity 14. The housing 1 is provided with an oil injection hole 112 that communicates with the receiving groove 13. When the lifting plate 41 moves to the point where the limiting post 43 abuts against the bottom wall of the receiving groove 13, the oil injection hole 112 communicates with the oil storage cavity 14. In this embodiment, the limiting post 43 is set to ensure the minimum oil storage capacity of the oil storage cavity 14, and oil can be injected into the oil storage cavity 14 through the oil injection hole 112 at the minimum oil storage capacity. Correspondingly, the position of the oil passage hole corresponds to the minimum oil storage capacity setting, that is, the oil passage hole is located near the bottom wall of the atomizing tube, thereby ensuring that when the limiting post 43 abuts against the bottom wall, the oil passage hole is located in the oil storage cavity 14. Thus, when the oil storage chamber 14 is at its minimum storage capacity, the oil can participate in atomization and generate an aerosol through the oil passage. It is worth noting that in some embodiments, the minimum oil storage capacity of the oil storage chamber 14 is allowed to be zero, i.e., the limiting post 43 is not configured. In this way, the oil storage chamber 14 can be completely emptied according to the user's needs.

[0052] In some embodiments, such as Figures 7-9 As shown, the atomizing heating device also includes at least one oil storage bottle 6. At least one oil passage member 5, communicating with the oil storage chamber 14, protrudes from the bottom wall of the receiving groove 13 away from the nozzle assembly 2. The oil storage bottle 6 is detachably installed on the oil passage member 5. In this embodiment, the detachable oil storage bottle 6 is used to replenish oil to the oil storage chamber 14. Furthermore, when the nozzle assembly 2 is rotated to completely empty the oil storage chamber 14, the oil storage bottle 6 can receive the oil stored in the oil storage chamber 14, facilitating the storage and transportation of the device and preventing oil leakage.

[0053] In some embodiments, the oil passage component 5 includes an oil passage pipe 51 and an installation pipe 52. The oil passage pipe 51 penetrates the bottom wall of the receiving groove 13, and one end is connected to the oil storage cavity 14. The oil passage pipe 51 can protrude into the oil storage cavity 14. The oil passage pipe 51 can also be flush with the bottom surface of the oil storage cavity 14, which ensures that the oil is completely drained. The other end of the oil passage pipe 51 extends out of the housing 1. The installation pipe 52 is arranged around the end of the oil passage pipe 51 that extends out of the housing 1. One end of the installation pipe 52 is fixedly connected to the housing 1, and forms an annular space with the outer periphery of the oil passage pipe 51 for installing the oil storage bottle 6. The other end protrudes away from the housing 1 and is provided with a connecting part 521. A detachable connection is established with the oil storage bottle 6 through the connecting part 521.

[0054] In some embodiments, the connecting portion 521 includes at least one elastic snap. At least one elastic snap is spaced apart along the circumferential direction of the mounting tube 52; it can be one, two, or more. Correspondingly, the outer periphery of the neck of the oil storage bottle 6 is provided with a matching annular groove 61. When the neck of the oil storage bottle 6 extends into the annular space until the elastic snap engages in the annular groove 61, the oil storage bottle 6 is installed in place, and at this time, the oil passage tube 51 is connected to the oil storage bottle 6. In practical applications, the connecting portion 521 can also adopt other connecting structures. For example, the connecting portion 521 can be an internal thread provided on the inner wall of the mounting portion, and the neck of the oil storage bottle 6 can be provided with a corresponding external thread 421, allowing the oil storage bottle 6 to be detachably installed on the oil passage component 5 through threaded engagement. In some embodiments, an oil-proof plug adapted to the oil passage component 5 can also be configured. When the oil storage bottle 6 is detached from the oil passage 5, the oil-proof plug is installed on the oil passage 5 to seal the oil storage cavity 14 and prevent oil from flowing out of the oil passage pipe 51. In practical applications, the oil-proof plug can be made of materials such as silicone, rubber, or silicone sealant, and its shape and size can be adapted to the oil passage pipe 51. The oil storage cavity 14 is sealed by blocking the oil passage pipe 51 with the oil-proof plug.

[0055] In some embodiments, such as Figure 8As shown, an oil valve 62 is provided at one end of the oil storage bottle 6 near the bottle opening. The oil valve 62 includes a fixing sleeve 621 and an elastic diaphragm 622 with at least one notch 623. The oil valve 62 can be an integral structure, that is, the fixing sleeve 621 and the elastic diaphragm 622 are integrally connected. Preferably, both the fixing sleeve 621 and the elastic diaphragm 622 are made of soft rubber material, such as silicone, rubber, or silicone rubber. The fixing sleeve 621 is fitted onto the bottle opening of the oil storage bottle 6, and the fixing sleeve 621 partially covers the inner wall of the oil storage bottle 6 and partially covers the outer periphery of the oil storage bottle 6. The elastic diaphragm 622 is located inside the oil storage bottle 6, and the outer periphery of the elastic diaphragm 622 is tightly connected to the portion of the fixing sleeve 621 covering the inner wall of the oil storage bottle 6. In this way, the elastic diaphragm 622 can completely seal the oil storage bottle 6, so that the oil in the oil storage bottle 6 cannot flow out through the elastic diaphragm 622. In practical applications, the elastic diaphragm 622 can be composed of at least two valves, in which case the gap between the valves forms the cut 623. The elastic diaphragm 622 can also be a single diaphragm with at least one cut 623.

[0056] Please refer to Figure 8 and Figure 9 Initially, the cut 623 is closed under elastic action, meaning the oil valve 62 is closed. When the oil storage bottle 6 is installed on the oil supply component 5, the oil supply pipe 51 extends into the oil storage bottle 6. That is, the side wall of the oil storage bottle 6 is accommodated in the annular space between the oil supply pipe 51 and the connecting pipe 23. At this time, the fixing sleeve 621 is partially clamped between the inner wall of the oil storage bottle 6 and the connecting pipe 23, and partially clamped between the outer wall of the oil storage bottle 6 and the connecting pipe 23. This allows the fixing sleeve 621 to not only fix the elastic diaphragm 622, but also to seal the connection gap between the oil storage bottle 6 and the oil supply component 5, preventing oil leakage from the gap between them during oil replenishment. At the same time, the oil supply pipe 51 pushes open the cut 623, the oil valve 62 is in the open state, and the oil storage bottle 6 and the oil storage chamber 14 are connected via the oil supply pipe 51. When the detachable connection between the oil storage bottle 6 and the oil supply component 5 is released, the oil supply pipe 51 disengages from the oil storage bottle 6, and the elastic diaphragm 622 recovers its elastic deformation, thereby causing the cut 623 to return to a closed state, thus closing the oil bottle. This embodiment employs an elastic oil valve 62 structure, which allows the oil valve 62 to automatically open and close during the oil replenishment process without requiring additional operation of the oil valve 62. This not only ensures reliable sealing but also facilitates user operation.
