Description

Technical Field

[0001] This utility model relates to the field of electronic atomizer technology, and in particular to a press-type oil-filling atomizing device and an electronic atomizer. Background Technology

[0002] Press-type e-filling is an existing e-filling method in atomizers that allows users to conveniently inject aerosols into the reservoir to form a matrix. The e-filling process is as follows: press the e-filling port control switch to open the e-filling port, so that the container storing the aerosol matrix is ​​connected to the reservoir chamber inside the reservoir. The external aerosol matrix flows into the reservoir chamber. After e-filling is completed, release or press the e-filling port control switch again to close the e-filling port.

[0003] However, existing control switches require an opening in the reservoir during assembly. The pressing part of the control switch passes through the opening and is exposed outside the reservoir. A seal is installed between the control switch and the opening to seal it. However, during the actuation process, the control switch will frequently rub against the opening or seal, creating gaps and causing the aerosol matrix in the reservoir to leak. Utility Model Content

[0004] The main purpose of this invention is to propose a press-type oil atomizing device and an electronic atomizer, in which the press part of the control switch can be placed in the liquid storage chamber, so as to solve the technical problems existing in the prior art.

[0005] To achieve the above objectives, this application provides a press-type oil atomizing device, comprising:

[0006] A first housing has an internally defined liquid storage chamber for storing an aerosol-forming matrix. The first housing has a non-flexible region and at least one flexible region capable of elastic deformation. The non-flexible region is provided with an inlet for introducing the aerosol-forming matrix.

[0007] A push-button switch has an operable lever and a valve, at least a portion of which is movably housed within the first housing. One end of the lever abuts against the non-flexible region or the flexible region, and the other end is connected to the valve, which is configured to move between a position blocking the inlet and a position opening the inlet under the action of the lever.

[0008] When the flexible area is pressed, the rod can be operated to move within the first housing.

[0009] At least a portion of the lever that receives user pressure from the push switch is sealed within the liquid reservoir. The user can repeatedly press the flexible area to operate the lever without needing to create an installation port on the first housing to assemble the push switch. This avoids the risk of aerosol matrix leakage caused by wear and tear between the push switch and the first housing during long-term operation.

[0010] In some embodiments, the first housing further includes a non-flexible region that, together with the flexible region, defines a receiving cavity, and one end of the rod is movably received within the receiving cavity.

[0011] Furthermore, the push switch also includes an elastic element, one end of which is connected to the rod and the other end of which is connected to the first housing. Under the elastic force of the elastic element, the valve covers the liquid inlet to form a seal on the liquid inlet.

[0012] In some embodiments, the push switch further includes an extension located on the side of the valve away from the rod, the end of the extension away from the valve extending axially along the rod.

[0013] In some embodiments, the first housing is provided with a gas channel, and the gas channel and the first housing define the liquid storage cavity, with one end of the gas channel connected to the outside of the first housing to form a suction nozzle.

[0014] In some embodiments, at least a portion of the gas passage extends through the liquid reservoir.

[0015] In some embodiments, a second housing is further included, the second housing having an internally formed supply chamber for storing an aerosol-forming matrix. The second housing is connected to the first housing via a fluid channel, the outlet end of the fluid channel being connected to the inlet end, and the inlet end of the fluid channel being connected to the supply chamber. The valve is disposed inside or outside the fluid channel to cover the outlet end or the inlet end.

[0016] In some embodiments, the first housing and the second housing are detachably connected.

[0017] Based on the above-described press-type oil-filling atomizing device, this application also provides an electronic atomizer, which includes an atomizing component and the press-type oil-filling atomizing device in any of the above embodiments, wherein the atomizing component is at least partially housed in the first housing and defines a liquid storage cavity with the inner wall of the first housing, an atomizing cavity is formed inside the atomizing component, and an inlet hole for communicating the atomizing cavity and the liquid storage cavity is provided on the atomizing component.

[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects: a flexible pressing area is formed on the surface of the electronic atomizer, and the pressing switch is wrapped in the liquid storage cavity. The gap between the pressing switch and the liquid storage cavity will not be exposed outside the liquid storage cavity, thus preventing the aerosol formation matrix from leaking from the liquid storage cavity to the outside of the shell.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] Please refer to Figures 1-5 As shown, this application provides a press-type oil atomizing device, which includes: a first housing 10 and a press switch 20. The first housing 10 defines a liquid storage chamber 100 for storing an aerosol forming matrix. The first housing 10 has a non-flexible region 11 and at least one flexible region 11 that can be elastically deformed. The non-flexible region 11 is provided with an inlet 12 for introducing the aerosol forming matrix. The press switch 20 has an operable rod 21 and a valve 22. At least a portion of the rod 21 is movably housed within the first housing 10. One end of the rod 21 abuts against the non-flexible region 11 or the flexible region 11, and the other end is connected to the valve 22. The valve 22 is used to move between a position blocking the inlet 12 and a position opening the inlet 12 under the action of the rod 21.

[0029] Users can operate lever 21 by repeatedly pressing the flexible area 11. As lever 21 moves within the liquid storage chamber 100, valve 22 moves from a position blocking the liquid inlet 12 to a position opening the liquid inlet 12, driven by lever 21. This avoids the need to create an installation port on the housing to assemble the push switch 20, and also prevents the push switch 20 from wearing down with the first housing 10 during long-term operation, which could lead to aerosol matrix leakage.

[0030] In some embodiments, the first housing 10 further includes a non-flexible region 11, which is integrally formed with the flexible region 11, meaning that the non-flexible region 11 and the flexible region 11 are an inseparable whole. It is understood that the rigidity of the non-flexible region 11 is greater than that of the flexible region 11, and it is not easily deformed. Therefore, the liquid inlet 12 is disposed in the non-flexible region 11, and the liquid inlet 12 is located within the non-flexible region 11 covered by the projection of the flexible region 11.

[0031] The first housing 10 is preferably made of food-grade material, such as PCTG for the non-flexible region 11, with silicone fused to the non-flexible region 11 at pre-reserved bonding positions, or TPU (polyurethane) for the flexible region 11. The flexible region 11 can define a receiving cavity, either independently or together with the non-flexible region 11, with one end of the rod 21 movably received within the receiving cavity. Alternatively, the flexible region 11 can be supported by the push-button switch 20 and protrude from the surface of the first housing 10 to form a noticeable protrusion.

[0032] Press switch 20 Figure 2 As shown, a rod 21 and a valve 22 are connected together. The rod 21 has an elongated shape, with one end approaching or abutting a flexible region 11, allowing the user to operate the rod 21 through the flexible region 11. The valve 22 is located at the end of the rod 21 away from the flexible region 11 and near the inlet 12. It is understood that the reservoir 100 has a closed state and an open state. When the valve 22 covers the inlet 12, the reservoir 100 is in a closed state; when the valve 22 is moved away from the inlet 12 by the rod 21, the reservoir 100 is in an open state, allowing external aerosol forming matrix to be injected into the reservoir 100 through the inlet 12. It is understood that... Figure 1 In this embodiment, valve 22 covers the outside of inlet 12. In some embodiments, valve 22 is disposed inside the liquid storage chamber 100, covering the inside of inlet 12, without affecting the effectiveness of valve 22.

[0033] Specifically, such as Figure 1 As shown, the top of rod 21 is positioned within the receiving cavity and close to the flexible region 11. After deformation, the flexible region 11 can contact the top of rod 21 and push rod 21 to move axially. Figure 3 As shown, the flexible area 11 deforms downward and abuts against the top of the rod 21 after being pressed by the user. The rod 21 moves downward under the pressure and drives the valve 22 away from the liquid inlet 12. The liquid inlet 12 opens, and the external aerosol matrix can be injected into the liquid storage chamber 100 through the liquid inlet 12 in the direction of the arrow.

[0034] See Figure 1As shown, the push-button switch 20 also includes an elastic element, which is a spring 14. The spring 14 is sleeved on the body of the rod 21, with one end connected to the rod 21 and the other end connected to the first housing 10. Specifically, a limiting platform 15 is provided inside the first housing 10. The spring 14 is installed between the rod 21 and the limiting platform 15. The rod 21 is supported by the elastic force of the spring 14 and abuts against the flexible area 11. At the same time, the valve 22 also covers the liquid inlet 12 under the elastic force. When an external force is applied to the push-button switch 20, the rod 21 moves downward and compresses the spring 14. The valve 22 moves away from the liquid inlet 12 under the action of the rod 21. When the external force is withdrawn, the rod 21 returns to its original position under the elastic force of the spring 14, and the valve 22 also covers the liquid inlet 12 after the rod 21 returns to its original position.

[0035] See Figure 2 As shown, the push-button switch 20 also includes an extension 23, which, along with the valve 22 and the rod 21, is connected in sequence. The extension 23 is at least partially located outside the liquid storage chamber 100. Understandably, during the injection of the external aerosol forming matrix, the extension 23 can break the surface tension of the fluid in the fluid channel to increase the flow rate of the aerosol forming matrix in the fluid channel.

[0036] like Figure 1 As shown, the press-type oil atomizing device also includes an atomizing component 30, and the first housing 10 serves as a carrier for the user to inhale the aerosol. A gas channel is provided inside the first housing 10, and a liquid storage chamber 100 is defined between the gas channel and the first housing 10. One end of the gas channel is connected to the outside of the first housing 10 to form a nozzle 13. The user inhales the atomized aerosol contained in the gas channel through the nozzle 13.

[0037] In some embodiments, to avoid the first housing 10 from becoming bulky, at least a portion of the gas passage passes through the liquid storage chamber 100, thereby appropriately compressing the liquid storage space of the liquid storage chamber 100.

[0038] The press-type oil atomizing device also includes a second housing 40. The second housing 40 has a liquid supply chamber 41 inside for storing the aerosol formation matrix. The second housing 40 is provided with a liquid outlet 42. The second housing 40 is connected to the first housing 10 through a fluid channel. The two ends of the fluid channel are respectively connected to the liquid outlet 42 and the liquid inlet 12.

[0039] See Figure 4 As shown, a fluid channel is provided between the first housing 10 and the second housing 40. The outlet of the fluid channel is connected to the inlet 12 of the first housing 10, and the inlet end of the fluid channel is connected to the supply chamber 41 of the second housing 40. The valve 22 is located inside or outside the fluid channel and covers the outlet or the inlet end.

[0040] In some embodiments, the first housing 10 and the second housing 40 can be detachably connected by means of plug-in connection, threaded connection, magnetic attraction, etc. Figure 4 As shown, the first housing 10 is provided with a receiving cavity 16 for receiving the second housing 40. Figure 5 As shown, at least a portion of the second housing 40 can be fitted into the receiving cavity 16. After the first housing 10 is connected to the second housing 40, when the rod 21 is pressed and moved, at least a portion of the extension 23 extends into the supply cavity 41 and breaks the liquid seal in the supply cavity 41. After the valve 22 opens the fluid passage, the aerosol forming matrix in the supply cavity 41 can be smoothly injected into the storage cavity 100.

[0041] Based on the aforementioned press-type oil-filling atomizing device, this application also provides an electronic atomizer, which includes an atomizing component 30 and the press-type oil-filling atomizing device as described in any of the above embodiments. The atomizing component 30 is at least partially housed within a first housing 10 and defines a liquid storage chamber 100 within the inner wall of the first housing 10. An atomizing chamber is formed inside the atomizing component 30, and an inlet hole is provided on the atomizing component 30 to connect the atomizing chamber and the liquid storage chamber 100. The aerosol forming matrix enters the atomizing chamber through the inlet hole and is atomized to form an aerosol.

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.
