Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
The first embodiment is as follows:
referring to fig. 1, an embodiment of the present invention provides an atomizer including an upper cap member and an atomizing member connected to each other, the upper cap member including an upper cap member 11 and an upper cap link 14 rotatably provided with respect to the upper cap member 11, the upper cap member 11 being provided with a first liquid injection hole 111, the upper cap link 14 being provided with a second liquid injection hole 141, and the connection area of the first liquid injection hole 111 and the second liquid injection hole 141 being changeable by rotating the upper cap member 11, the upper cap member 11 and the upper cap link 14 being in smooth contact with each other at their radial connection surfaces.
Referring to fig. 1 to 3, according to the atomizer of the present embodiment, since the upper cover assembly 11 and the upper cover connecting member 14 are both made of ceramic, and the radial connecting surfaces of the upper cover assembly 11 and the upper cover connecting member 14 are smooth, specifically, the radial connecting surfaces include the first surface 121 located on the upper cover assembly 11 and the second surface 122 located on the upper cover connecting member 14, when assembling, the first surface 121 and the second surface 122 are in smooth contact, and the smooth refers to that the flatness of the first surface 121 and the flatness of the second surface 122 are not more than 0.04 μm, and the roughness is not more than 0.007 μm. The flatness and roughness requirements can be easily met through the prior art and process equipment, mass production can be realized, the yield is high, and the sealing effect required by the technical scheme can be realized.
With the above design, when the atomizer is filled or carried by a user, a part of the aerosol-forming substrate enters into the gap at the connection between the cap assembly 11 and the cap connector 14, i.e. the space between the connection surfaces (the first surface 121 and the second surface 122), and the aerosol-forming substrate presses out the air therein, and the cap assembly 11 and the cap connector 14 are kept in a sealed connection under the action of the external atmospheric pressure. Ceramic materials are easier to machine to the desired flatness and roughness than metal parts, and because of durability considerations, metal parts may corrode, while ceramic materials have good corrosion resistance.
The atomizer of this embodiment is further provided with an annular groove 22 on the upper cover assembly 11, and the suction nozzles of different shapes can be detachably clamped or screwed on the upper cover assembly 11 through the groove 22, so that the suction nozzles can be conveniently replaced when a user needs to replace the suction nozzles. Because the upper cover part is made of ceramics, compared with the traditional electronic cigarette, most of the electronic cigarette is made of stainless steel materials, and the heat conduction effect of the ceramics is poorer than that of the stainless steel, so that the electronic cigarette has a certain scald preventing function.
Referring to fig. 1, the atomizer further includes an outer tube 16 and an atomizing component, the atomizing component includes an outer tube 17, an inner tube 18 and an atomizing base 20, the outer tube 17 is fastened to the atomizing base 20, the upper cover connector 14 is connected to the outer tube 16 through a thread seal, the upper end of the outer tube 17 is connected to the upper cover connector 14 through a thread, and the lower end of the outer tube 17 is fastened to the atomizing base 20. In the embodiment, the outer sleeve 17 is fastened to the atomizing base 20 by a screw, and those skilled in the art will appreciate that the same technical effect can be achieved by snapping or screwing. The cavity between the outer tube 16, the atomising base 20, the upper cap connector 14, and the outer sleeve 17 forms a reservoir for the aerosol-forming substrate. While the bottom of the inner sleeve 18 has an inwardly formed cavity (not labeled) for receiving an atomizing cartridge. To prevent leakage of aerosol-forming substrate from the connection of the components, the present embodiment is provided with resilient sealing members 15, in particular rubber or other resilient material, between the upper cap connector 14 and the outer tube 16 and between the atomising base 20 and the outer tube 16, and further with O-rings 19 at the connection of the top end of the outer sleeve 17 and the upper cap connector 14. In this way, leakage of the aerosol-forming substrate outwards may be further prevented.
Referring to fig. 1 and 2, the upper cover part is provided with a first through hole 113, the inner sleeve 18 passes through the first through hole 113 to be in interference fit with the upper cover part 11, and the inner sleeve 18 can be driven to rotate when the upper cover part 11 is rotated. The outer sleeve 17 is provided with a first liquid inlet 21, the inner sleeve 18 is provided with a second liquid inlet 22, and the upper cover assembly 11 is rotated to drive the inner sleeve 18 to rotate, so that the communication area between the first liquid inlet 21 and the second liquid inlet 22 is changed.
Preferably, since rotating the cap assembly 11 will rotate the inner sleeve 18, so as to change the communication area between the first inlet 21 and the second inlet 22, according to one embodiment of the present invention, when the cap assembly 11 is rotated to a certain position to communicate the first liquid injection hole 111 with the second liquid injection hole 141, the first inlet 21 and the second inlet 22 are closed in a staggered manner. Thus, the outer sleeve 17 and the atomizing base 20 are fixedly connected and relatively fixed, and the rotating upper cover assembly 11 can drive the inner sleeve 18 to rotate together, so that when a user needs to inject liquid, the upper cover assembly 11 can be rotated to reach a first preset position, at the moment, the first liquid injection hole 111 and the second liquid injection hole 141 are aligned and communicated, the first liquid inlet 21 and the second liquid inlet 22 of the atomizing part are closed due to the fact that the outer sleeve 17 is fixed and the inner sleeve 18 rotates, aerosol forming substrates in the liquid storage cavity cannot enter the atomizing core through the first liquid inlet 21 and the second liquid inlet 22, and therefore the situation that when liquid is injected, the aerosol forming substrates enter the atomizing cavity through the first liquid inlet 21 and the second liquid inlet 22, and too much aerosol forming substrates are accumulated in the atomizing cavity is avoided.
Referring to fig. 1 to 3, according to a preferred embodiment of the present embodiment, the upper cover member further includes a moving member through which the upper cover assembly 11 is rotatably provided on the upper cover coupling member 14, and a movement stopper which limits the movement of the moving member at a predetermined position. Specifically, in one embodiment, the moving element is a ball 12, the motion stop portion is a recess 112 disposed in the upper cover assembly 11, the upper cover connecting member 14 is disposed with a blind hole 142, and the ball 12 is disposed in the blind hole 142. For example, as shown in fig. 2-3, in one embodiment, the number of the first pour hole 111 and the number of the second pour hole 141 are 2, the number of the blind holes 142 is 2, the number of the dimples 112 is 4, the number of the blind holes 142 and the two second pour holes 141 are located on the same diameter passing through the center of the first through hole 113, and the number of the dimples 112 is symmetrically distributed on the top lid assembly 11 with reference to the center of the first through hole 113. Thus, when the ball 12 is disposed in the blind hole 142, and the lid assembly 11 is rotated, the lid assembly 11 can reach a specific position by rotating the lid assembly 11 by 90 °, and assuming that the first pour hole 111 and the second pour hole 141 are aligned and communicated with each other exactly at this position, if the lid assembly 11 is rotated by 90 °, the lid assembly 11 will reach another specific position, and at this time, the first pour hole 111 and the second pour hole 141 are not communicated with each other. Since the 4 pits are symmetrically distributed, every 90 degrees of rotation will make the lid assembly 11 reach a specific position, so that the first pour hole 111 and the second pour hole 141 are communicated or not communicated, and the process is repeated. After understanding the inventive concept of the present embodiment, it is obvious for those skilled in the art to design other modified embodiments, for example, the number of the blind holes 142 is 3, the number of the pits 112 is 6, and so on, and these schemes are not described again. Preferably, in one embodiment of the present invention, the moving member further includes a spring 13, and the spring 13 is disposed at the bottom of the blind hole 142, and supports the ball 12 such that the ball 12 is kept in contact with the lid assembly 11, so that a good feel can be obtained when the lid assembly 11 is rotated.
Example two:
referring to fig. 4, the second embodiment of the present invention provides an atomizer comprising an upper cap member and an atomizing member which are connected to each other, the upper cap member comprising an upper cap member 11 and an upper cap link 14 which are both made of ceramic and are rotatably provided with respect to the upper cap member 11, the upper cap member 11 being provided with a first liquid injection hole 111, the upper cap link 14 being provided with a second liquid injection hole 141, the area of communication between the first liquid injection hole 111 and the second liquid injection hole 141 being changeable by rotating the upper cap link 14, and the connecting surfaces of the upper cap member 11 and the upper cap link 14 in the axial direction thereof being in smooth contact with each other. Similar to the first embodiment, the connection surface 24 includes an outer circumferential surface (not labeled) of the upper cover assembly 11 and an inner circumferential surface (not labeled) of the upper cover connector 14, when assembled, the upper cover connector 14 is sleeved on the outer circumference of the upper cover assembly 11, the outer circumferential surface of the upper cover assembly 11 is in smooth contact with the inner circumferential surface of the upper cover connector 14, and the smoothness means that the flatness of the outer circumferential surface of the upper cover assembly 11 and the inner circumferential surface of the upper cover connector 14 do not exceed 0.04 μm, and the roughness does not exceed 0.007 μm. The flatness and roughness requirements can be easily met through the prior art and process equipment, mass production can be realized, the yield is high, and the sealing effect required by the technical scheme can be realized.
Referring to fig. 4, according to a preferred embodiment of the present embodiment, the atomizer further includes an outer tube 16, and the atomizing component further includes a first vent pipe 42, a second vent pipe 43 and an atomizing base 20, as shown in fig. 4, the first vent pipe 42 and the second vent pipe 43 are fixedly connected in series, and the lower end of the first vent pipe 42 is fixedly connected to the atomizing base 20, so that the space between the outer tube 16, the atomizing base 20, the upper cover assembly 11, the first vent pipe 42 and the second vent pipe 43 forms a liquid storage cavity, and as mentioned above, the communicating area of the first liquid injection hole 111 and the second liquid injection hole 141 can be changed by twisting the upper cover connecting piece 14, thereby facilitating the liquid injection by the user.
Referring to fig. 4, according to a preferred embodiment of the present embodiment, the atomizer further includes a mouthpiece connecting member 51, the mouthpiece connecting member 51 is fixed at the uppermost end of the whole atomizer, and the mouthpiece connecting member 51 is detachably connected to the second ventilation pipe 43, as shown in fig. 4, the mouthpiece connecting member 51 is connected to the second ventilation pipe 43 by a screw thread, however, the two may be fixedly connected by other means, such as clamping, thermal welding, ultrasonic welding, etc. The upper end of the upper cover assembly 11 is tightly fitted to the bottom surface of the mouthpiece connector 51, and the lower end of the upper cover assembly 11 is interference fitted to the outer tube 16.
According to another aspect of the invention, there is also provided an electronic cigarette comprising the nebulizer of any one of the preceding claims. Due to the technical effects brought by the atomizer, the electronic cigarette applying the atomizer can bring the same technical effects. Taking the first embodiment as an example, the electronic cigarette according to the present invention has the following working principle: interior sleeve pipe 18 establishes with outer tube 17 cover and forms the atomizing cavity, and the atomizing cavity embeds there is the atomizing core, and interior sleeve pipe 18 corresponds with outer tube 17 week side and sets up the inlet and can feed through or close, and when the inlet intercommunication of the two, aerosol formation substrate enters into the atomizing intracavity, generates heat when the switch-on by the atomizing core and atomizes it to form smog. Because the inner sleeve 18 is hollow, an air flow channel is formed and is communicated with the suction nozzle, a user can suck through the suction nozzle, and the smoking feeling is generated. In one embodiment, if the liquid injection operation is performed, the upper cover assembly 11 can be rotated to open the liquid injection hole and close the liquid inlet, thereby preventing liquid leakage from the bottom of the atomizer during liquid injection.
