Description

Technical Field

[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to an electronic atomizer with a self-locking oil filling structure. Background Technology

[0002] Existing electronic atomizers include a separable liquid reservoir and an atomizing unit. The atomizing unit has a pre-stored atomizing matrix in the oil tank and an atomizing coil. After the liquid reservoir can be combined with the atomizing unit, the atomizing matrix in the liquid reservoir can be transferred to the oil tank.

[0003] When the existing liquid storage container is not in use, the seal at the liquid outlet can be accidentally broken by minors or users, causing the atomizing matrix inside the liquid storage container to leak out. In addition, when the liquid storage container is separated from the atomizing host, the liquid outlet cannot seal itself, causing some atomizing matrix to spill out of the liquid storage container's liquid outlet. Utility Model Content

[0004] The main purpose of this invention is to propose an electronic atomizer with a self-locking oil filling structure, which can solve the problems in the prior art where the seal of the liquid storage container is easily broken and the liquid storage container cannot seal itself after being separated from the atomizer.

[0005] To achieve the above objectives, this application provides an electronic atomizer with a self-locking filling structure, comprising a housing and a liquid reservoir. The housing has an oil chamber and a connecting portion, the connecting portion communicating with the oil chamber, and the liquid reservoir being detachably connected to the connecting portion.

[0006] The liquid storage bottle includes:

[0007] The bottle body has a liquid storage chamber inside which atomized matrix is ​​stored. The bottle body has a bottle mouth that communicates with the liquid storage chamber. The bottle mouth defines a receiving cavity inside which a second deflection structure is provided.

[0008] A lock, wherein the lock is disposed within the accommodating cavity and is movable between a locked position and an unlocked position, wherein the lock is provided with a fluid channel, a third deflection structure and a latching protrusion;

[0009] An elastic element is provided to support the lock in the locked position within the accommodating cavity;

[0010] When the liquid storage bottle is connected to the connecting part, the lock is rotated to the unlocked position, thereby allowing the lock to move toward the liquid storage cavity and connect the oil tank to the liquid storage cavity through the fluid channel;

[0011] When the liquid storage bottle is separated from the connecting part, the lock moves towards the bottle opening under the elastic force of the elastic member and closes the liquid storage cavity. The locking protrusion engages with the second deflection structure and deflects the lock and moves it to the locked position.

[0012] Compared with the prior art, in the embodiments of this application, when the liquid storage bottle is in use, it is connected to the connecting part on the electronic atomizer, and the lock is rotated to the unlocked position, so that the lock can move to the side of the liquid storage cavity and connect the oil tank and the liquid storage cavity through the fluid channel; when the liquid storage bottle is not in use, the liquid storage bottle is in an independent state, and the elastic element supports the lock to close the liquid storage cavity; or when the liquid storage bottle is separated from the connecting part, the latch engages with the second deflection structure and deflects the lock and moves it to the locked position, and the elastic element continuously supports the lock to close the liquid storage cavity.

[0013] In some embodiments, the connecting portion is provided with a first deflection structure having a toothed end face and a liquid inlet channel that can connect to the oil tank. When the first deflection structure and the third deflection structure are combined, the lock can be rotated to the unlocked position or the locked position.

[0014] In some embodiments, the bottle body includes a positioning sleeve fixed to the bottle mouth, the positioning sleeve forming at least a portion of the accommodating cavity, the positioning sleeve being a cylindrical structure open at both ends, one end of the positioning sleeve being connected to the bottle body to form the bottle mouth, and the other end of the positioning sleeve being disposed within the accommodating cavity to form a second deflection structure having a toothed end face.

[0015] In some embodiments, the receiving cavity has a first end communicating with the liquid storage cavity and a second end capable of receiving the connection portion, and the receiving cavity is provided with a guide groove on the side near the first end.

[0016] In some embodiments, the lock includes an outer cylinder and an inner cylinder. The interior of the inner cylinder defines a fluid channel, and the outer wall of the inner cylinder has a liquid inlet communicating with the fluid channel. The outer cylinder is sleeved on the inner cylinder. One end of the outer cylinder near the bottle opening extends axially to form a third deflection structure with a toothed end face. The outer cylinder extends towards the end near the liquid inlet to form a guide block. The locking mechanism is protrudingly disposed on the outer cylinder. A receiving cavity is defined between the inner wall of the outer cylinder and the outer wall of the inner cylinder. One end of the elastic element is received in the receiving cavity, and the other end of the elastic element is connected to the bottle body. When the liquid storage bottle is connected to the connecting part, the first deflection structure and the third deflection structure combine to rotate the lock to the unlocked position, and the guide block can be inserted into the guide groove.

[0017] In some embodiments, the cross-section of the liquid inlet is any one of elliptical, circular, rectangular, or triangular.

[0018] In some embodiments, the cam is aligned with the root of the tooth on the toothed end face of the third deflection structure.

[0019] In some embodiments, one end of the outer cylinder and one end of the inner cylinder are connected to form a closed end of the receiving cavity, and the other ends of the outer cylinder and the inner cylinder are spaced apart to define an open end forming the receiving cavity.

[0020] In some embodiments, the inner cylinder extends radially at one end near the liquid inlet to form a skirt, the skirt being exposed within the liquid storage cavity, and the skirt abutting against the inner wall of the liquid storage cavity under the elastic force of the elastic member to seal the liquid storage cavity.

[0021] In some embodiments, the liquid storage bottle further includes a seal fixed to the inner cylinder and exposed within the liquid storage cavity by the skirt.

[0022] Based on the above-mentioned electronic atomizer, when the liquid storage bottle is installed on the electronic atomizer, the lock is forced to compress the elastic element. At the same time, the lock is forced to move towards the liquid storage chamber, exposing the liquid inlet inside the liquid storage chamber, so that the liquid storage bottle and the electronic atomizer are in fluid communication. When the liquid storage bottle is separated from the electronic atomizer, the lock moves towards the bottle opening under the elastic force of the elastic element, so that the liquid inlet is hidden in the mounting hole, and the locking protrusion abuts against the first toothed end face. The locking protrusion moves along the contour of the first toothed end face and causes the lock to deflect. At the same time, the guide block separates from the guide groove and is misaligned. At this time, the guide block cannot be inserted into the guide groove again in the vertical movement direction. Attached Figure Description

[0048] Electronic atomizers can be used in various fields, such as medical atomization, beauty atomization, and cigarette alternatives. They primarily work by heating an atomization substrate to generate an aerosol, which can be a liquid substrate containing or without nicotine. Electronic atomizers generally consist of an atomization assembly and a power supply assembly. The atomization assembly includes a reservoir that stores the atomization substrate and a coil. The reservoir stores the substrate, and the coil heats and atomizes it to generate an aerosol. The power supply assembly provides power to the coil.

[0049] See Figures 1-15As shown, this application provides an electronic atomizer with a self-locking oil filling structure. The electronic atomizer 2 includes a housing 20 and a liquid storage bottle 1. The housing 20 has an oil tank 21 inside, and a connecting part 22 on the housing 20 communicates with the oil tank 21. The liquid storage bottle 1 is detachably connected to the connecting part 22. The liquid storage bottle 1 is provided with a lock 14 that can open or close the liquid storage bottle 1. After the liquid storage bottle 1 is connected to the connecting part 22, the liquid storage chamber 103 communicates with the oil tank 21; after the liquid storage bottle 1 is separated from the connecting part 22, the lock 14 closes the liquid storage chamber 103.

[0050] like Figure 15 As shown, the connecting part 22 of the housing 20 of the electronic atomizer 2 is constructed as a first deflection structure 221 of an outwardly extending toothed cylinder. The teeth of the first deflection structure 221 are roughly triangular, and the tooth surface is an inclined outward curved surface or a plane.

[0051] The liquid storage bottle 1 includes a bottle body 10, a lock 14, and an elastic element. The lock 14 internally defines a fluid channel 1410 that connects the inner and outer spaces of the bottle body 10. One end of the elastic element is connected to the bottle body 10, and the other end is connected to the lock 14. The elastic element supports the lock through its elastic force, positioning the lock 14 in a corresponding locked position. The liquid storage cavity 103 is sealed by closing the fluid channel 1410. When the lock 14 is compressed by an external force, the lock 14 can rotate relative to the bottle body 10 to a corresponding unlocked position. The lock 14 moves towards the liquid storage cavity 103 until the liquid storage cavity 103 is connected to the external space of the bottle body 10 through the fluid channel 1410.

[0052] like Figure 3 As shown, the storage bottle 1 includes a bottle body 10, the interior of which defines a storage chamber 103 for storing the atomized matrix. The bottle body 10 has mounting holes 100. The mounting holes 100 are three-stage stepped holes, with a large hole 101, a middle hole, and a small hole 104 sequentially arranged from the outside of the bottle body 10 towards the inside. The large hole 101 has a downwardly extending second deflection structure 132 on its inner circumference, and the inner wall of the middle hole has an axially extending guide groove 102. The guide groove 102 opens upwards and extends downwards from the step between the large hole 101 and the middle hole. It can be understood that the large hole 101 connects to the external space of the bottle body 10, the small hole 104 connects to the storage chamber 103, and the middle hole connects the large hole 101 and the small hole 104.

[0053] In some embodiments, the liquid storage bottle 1 further includes a positioning sleeve 13 fixed within the mounting hole 100, see [reference]. Figure 9As shown, the positioning sleeve 13 is a cylindrical structure with open ends. The upper end of the positioning sleeve 13 is provided with a connecting port 131, and the lower end of the positioning sleeve 13 is close to the small hole 104, and its lower end extends towards the lock 14 to form a second deflection structure 132 with multiple protruding triangular teeth. It can be understood that the connecting port 131 can be connected to the bottle body to form the bottle mouth 11 of the liquid storage bottle 1. In addition, the second deflection structure 132 can be directly formed on the inner wall of the large hole 101, that is, multiple protruding triangular teeth are formed on the inner wall of the large hole 101, and the tips of the triangular teeth point downwards. The included angle between the two inclined surfaces of the triangular teeth is an acute angle. The inclined surfaces can be curved surfaces with outward curves or flat surfaces.

[0054] Each tooth of the second deflection structure 132 has curvature, defining a general direction or angle from the tooth tip to the tooth root. When the lock 14 abuts against the second deflection structure 132, the lock 14 can move along the contour of the second deflection structure 132 under the support of the elastic element, that is, the lock 14 rotates circumferentially. It is worth noting that the positioning sleeve 13 can be directly integrally formed with the bottle body 10.

[0055] In some embodiments, when the liquid storage bottle 1 is combined with the external structure, the external structure can be inserted from the connection port 131 and then connected to the lock 14.

[0056] The lock 14 is provided with a fluid channel 1410 having a liquid outlet 1400 and a liquid inlet 1412. For example... Figures 2-5 As shown, the outlet 1400 of the lock 14 connects to the outside of the bottle body 10, and the inlet 1412 connects to the liquid storage cavity 103 inside the bottle body 10. The axis of the inlet 1412 is perpendicular to the axis of the mounting hole 100. The cross-section of the inlet 1412 can be any one of elliptical, circular, rectangular, or triangular. It is understood that there are multiple inlets 1412; multiple inlets 1412 not only increase the inlet area but also prevent the surface tension of the atomizing matrix from blocking the inlets 1412.

[0057] like Figures 5-9 As shown, the lock 14 is provided with a third deflection structure 1402, a locking protrusion 1404, and a guide block 1403 for use with external structures. The third deflection structure 1402 is constructed on the end face of the lock 14 opposite to the second deflection structure 132. The third deflection structure 1402 has a plurality of teeth extending outward toward the bottle body 10, the sides of which are beveled, and the central axis of the third deflection structure 1402 is offset from the central axis of the second deflection structure 132. The locking protrusion 1404 is distributed circumferentially on the outer wall of the lock 14 and extends radially. The locking protrusion 1404 can abut against the second deflection structure 132 when the lock 14 moves upward. The guide block 1403 extends axially along the mounting hole 100 to be parallel to the extension direction of the guide groove 102.

[0058] It is worth noting that the structure of the third deflection structure 1402 can be the same as that of the second deflection structure 132, roughly triangular in shape. The side of the third deflection structure 1402 can be an outwardly curved surface or a plane.

[0059] The lock 14 includes an outer cylinder 140 and an inner cylinder 141. The inner wall of the outer cylinder 140 and the outer wall of the inner cylinder 141 define a receiving cavity 16. One end of the elastic element is connected to the lock 14 in the receiving cavity 16, and the other end of the elastic element is connected to the bottle body 10.

[0060] like Figure 6 As shown, the outer cylinder 140 is open at both the top and bottom. Multiple axially extending teeth are provided on the side of the outer cylinder 140 near the liquid outlet 1400, defining a third deflection structure 1402. Multiple guide blocks 1403 extend from the outer cylinder 140 towards the side near the liquid inlet 1412, each guide block 1403 being constructed on the outer wall of the outer cylinder 140 along the axis between two adjacent toothed end faces. Furthermore, a locking protrusion 1404 is constructed on the outer wall of the outer cylinder 140. Figure 7 As shown, there are two locking protrusions 1404, which are respectively constructed on the extension axis of the guide block 1403, and the locking protrusions 1404 radially protrude from the outer wall of the outer cylinder 140.

[0061] The inner cylinder 141 has an open upper portion and a closed bottom. The axial length of the inner cylinder 141 is greater than that of the outer cylinder 140. When the outer cylinder 140 is fitted onto the inner cylinder 141, a portion of the inner cylinder 141 is exposed outside the outer cylinder 140. A liquid inlet 1412 is located on the side of the exposed portion of the inner cylinder 141, and a fluid channel 1410 is constructed within the inner cylinder 141. In some embodiments, the outer diameter of the outer cylinder 140 is greater than the inner diameter of the intermediate hole of the mounting hole 100, such that the larger hole 101 section of the mounting hole 100 constitutes the range of motion of the lock 14.

[0062] In some embodiments, the inner cylinder 141 and the outer cylinder 140 are connected on the side near the liquid outlet 1400 to form a lock 14, and a closed end is formed at the connection between the inner cylinder 141 and the outer cylinder 140. A receiving cavity 16 is formed between the outer wall of the inner cylinder 141 and the inner wall of the outer cylinder 140, and one end of the elastic member extends into the receiving cavity 16 and is connected to the lock 14.

[0063] In some embodiments, the outer cylinder 140 is sleeved on the inner cylinder 141, and the outer cylinder 140 and the inner cylinder 141 are flush at one end and connected to form a closed end and an open end. A receiving cavity 16 is formed between the outer wall of the inner cylinder 141 and the inner wall of the outer cylinder 140. The closed end of the inner cylinder 141 extends radially to form a skirt, which is exposed in the liquid storage cavity 103. Under the elastic force of the elastic member, the skirt abuts against the inner wall 105 of the liquid storage cavity 103 to seal the liquid storage cavity 103.

[0064] In the above embodiment, one end of the elastic element is connected to the bottle body 10, and the other end of the elastic element is inserted into the receiving cavity 16 and connected to the lock 14. The elastic element provides a force to pull the lock 14 away from the liquid storage cavity 103, so that the liquid inlet 1412 is recessed into the mounting hole 100, blocking the communication between the fluid channel 1410 and the liquid storage cavity 103. It is understood that the elastic element can be an elastic block made of elastic material, or it can be a spring 15. Figure 7 As shown, the elastic element is a spring 15, which is sleeved on the inner cylinder 141. One end of the spring 15 abuts against the receiving cavity 16, and the other end of the spring 15 abuts against the step between the middle hole and the small hole 104.

[0065] In some embodiments, the reservoir 1 further includes a seal 12, which is secured to the lock 14 and exposed within the reservoir cavity 103 along with the skirt. (Reference) Figure 10 As shown, the sealing element 12 is a sealing ring, which is fitted onto the lock 14.

[0066] In some embodiments, the bottle body 10 protrudes outward at least partially to form a bottleneck with a length, the mounting hole 100 penetrates the bottleneck and communicates with the liquid storage cavity 103 and defines one end of the mounting hole 100 as the bottle mouth, the bottleneck is provided with an annular groove, and a tensioning member is engaged in the annular groove, the tensioning member is used to make the liquid storage bottle 1 and the shell 20 tighten together.

[0067] Understandably, reference Figure 10 As shown, when the liquid storage bottle 1 is not in use, the lock 14, under the elastic force of the elastic element, is axially offset away from the liquid storage cavity 103 within the mounting hole 100. The latching protrusion 1404 can abut against the second deflection structure 132, and the liquid inlet 1412 on the lock 14 is concealed within the mounting hole 100 as the lock 14 moves away from the liquid storage cavity 103. It is understood that the latching protrusion 1404 slides along the contour of the second deflection structure 132 and restricts the deflection of the lock 14. The guide block 1403 can be misaligned with the guide groove 102 when the lock 14 is deflected. When the guide block 1403 is misaligned with the guide groove 102, the guide block 1403 abuts against the step between the large hole 101 and the intermediate hole, and the lock 14 cannot move towards the liquid storage cavity 103.

[0068] refer to Figure 11As shown, the liquid storage bottle 1 is in use. The third deflection structure 1402 is driven by external force to compress the spring 15, and the lock 14 moves downward. The latch 1404 separates from the second deflection structure 132, and the side of the teeth of the third deflection structure 1402 is subjected to force. When the lock 14 moves downward, it is forced to turn, rotating the guide block 1403 to a position opposite to the guide groove 102. The lock 14 can continue to move downward and insert the guide block 1403 into the guide groove 102 until the liquid inlet 1412 is exposed in the liquid storage cavity 103. The guide block 1403 completes its movement stroke and abuts against the step between the middle hole and the small hole 104 of the mounting hole 100. At this time, the liquid inlet 1410 is exposed in the liquid storage cavity 103, and the liquid storage cavity 103 is connected to the external space through the fluid channel 1410.

[0069] like Figure 12-13 As shown, after the liquid storage bottle 1 is connected to the shell 20, the connecting part 22 is inserted into the bottle mouth 11. The first deflection structure 221 presses against the third deflection structure 1402, forcing the lock 14 to compress the spring 15. At the same time, the third deflection structure 1402 causes the lock 14 to deflect under the pressure of the first deflection structure 221. The lock 14 turns, and the guide block 1403 rotates from a position opposite to the guide groove 102 to a position opposite to the guide groove 102. The lock 14 continues to move downward until the liquid inlet 1412 is exposed in the liquid storage chamber 103. The atomized matrix stored in the liquid storage chamber 103 can be transferred to the oil tank 21 through the fluid channel 1410.

[0070] like Figure 14-15 As shown, when the liquid storage bottle 1 is separated from the shell 20, the connecting part 22 is pulled out from the bottle mouth 11, and the liquid storage bottle 1 returns to the unused state: the lock 14 moves towards the bottle mouth 11 under the elastic force of the spring 15, and the liquid inlet 1412 is hidden in the mounting hole 100. The skirt on the lock 14 abuts against the inner wall 105 of the liquid storage cavity 103, sealing the liquid storage cavity 103. At the same time, the latch 1404 abuts against the second deflection structure 132. The latch 1404 moves along the contour of the second deflection structure 132 and deflects the lock 14. The guide block 1403 rotates to a position that is offset from the guide groove 102. At this time, when the lock 14 is driven by a vertical external force, the guide block 1403 cannot align with the guide groove 102, and the lock 14 cannot descend under the support of the spring 15. The liquid storage cavity 103 remains in a closed state.

All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
