Description

Button mounting structure and atomizing device

Technical Field

Background

Current atomizing devices generally include a housing, a power source, an atomizing heating element, and a power switch that is capable of controlling the on-off of a circuit between the power source and the atomizing heating element. When the power switch is turned off, the power supply supplies power to the atomizing heating element, the atomizing heating element heats the aerosol generating oil or the aerosol generating rod to generate aerosol, and when the power switch is turned off, the power supply stops supplying power to the atomizing heating element, and the atomizing heating element stops working.

As the atomizing device may contact water in the environment of use, for example: the hands of the user may be wet or the atomizer may be splashed, and the atomizer needs to be waterproof in order to increase the life of the atomizer. At present, a key hole is usually formed in a shell, the key hole is sealed by adopting an encapsulation piece, and a key for pressing a power switch is arranged on the outer side of the encapsulation piece. Since the keys are installed from the outside, a fixing member is currently generally required to press the keys and the encapsulation member together. Usually, the fixing piece is fixed on the shell in an adhesive mode, and because the fixing piece needs to have certain pressing force on the key, the fixing piece is easy to lift up and tilt by the key after the assembly is completed, and when the fixing piece is pressed, the key is easy to move to trigger the switch, so that the technical problem of large assembly error exists in the key.

At present, a key installation structure of an atomization device is generally formed by making an encapsulation piece in the lower side of a key, namely, the key is firstly sealed in the interior and then is installed from the outer side, and a fixing piece is needed to press the key. The key mounting structure of this type has the following problems: the manufacturing cost of the rubber coating piece is high; the product needs to be disassembled for key assembly, and the fixing piece is needed to be assembled after the key is assembled, so that the appearance cannot be integrated; in order to prevent the key from shaking and generating a virtual position, the key needs to be pre-pressed, the key is subjected to outward elastic force, and thus when an external fixing piece is fixed by back glue, the external fixing piece is easily lifted up by the key, the key can be started by pressing the fixing piece, and the assembly error is large. In addition, the assembly hand feeling of the key is also easily influenced by the variation of the assembly tolerance of parts, and the capability of adapting to errors is weak.

The key installation structure adopts a new structural design, the baffle plate and the key cap are sequentially arranged in the key hole by adding the baffle plate, the baffle plate is blocked by the blocking structure arranged in the key hole, the fixing piece is not required to be additionally arranged for pressing the key, the assembly error is reduced, and the shell can realize the integrated design.

The key mounting structure and the atomizing device using the same according to the present utility model will be described in detail with reference to specific embodiments.

In some embodiments, please refer to fig. 1 and 2, the atomizing device includes a key mounting structure, an atomizing heating member (not shown in the drawings), and a pressed member 1, and the key mounting structure includes a housing 2, a sealing member 3, and a key 4. Referring to fig. 4, the atomizing device further includes a power source 5 disposed in the housing 2, and the power source 5 supplies power to the atomizing heating element.

In one embodiment, the atomizing heating member is a heating member for heating the aerosol-generating oil, and in this case, the heating member may be a heating mesh, and the aerosol-generating oil is heated and atomized after contacting the heating mesh. In some other embodiments, the atomizing heating member may also be a heating member for heating an aerosol-generating rod inserted into the housing 2, in which case the heating member may be a heating tube into which the aerosol-generating rod is inserted.

Referring to fig. 5 and 6, the housing 2 is provided with a key hole 21, and the key hole 21 has an outer side opening 211 toward the outside of the housing 2 and an inner side opening 212 toward the inside of the housing 2. Referring to fig. 2, the seal 3 is used to seal the inner port 212. Specifically, the sealing member 3 may be any feasible manner, for example, the sealing member 3 may be a conventional rubber-coated member, or the sealing member 3 shown in fig. 2 may be used, and the structure of the sealing member 3 will be described in detail below; the seal 3 may also be an elastic membrane that seals the inner port 212 and is inside the housing 2. The sealing member 3 according to the present utility model seals the inner port 212, which includes a form in which the sealing member 3 is press-tightly fitted with the housing 2, or a form in which the sealing member 3 is bonded or injection-molded with the housing 2 to seal the inner port 212.

Referring to fig. 2 and 3, the key 4 is installed in the key hole 21 and is located outside the sealing member 3. The key 4 includes a blocking piece 41 and a key cap 42 located outside the blocking piece 41, and the blocking piece 41 is used for being clamped into the key hole 21 and movably configured in the key hole 21. The wall of the key hole 21 has a stop structure having a stop surface 213 for stopping the tab 41, the stop surface 213 facing away from the outer opening 211 to limit the tab 41 from exiting the key hole 21 from the outer opening 211.

Specifically, the blocking piece 41 may be clamped into the key hole 21 in any feasible manner, which satisfies that the blocking piece 41 can be installed into the key hole 21 and blocked by the blocking structure, and cannot be separated from the key hole 21 under the action of elastic force, for example, the blocking piece 41 is clamped into the key hole 21 after the blocking piece 41 is elastically deformed, and the blocking piece 41 is in blocking fit with the blocking structure in a state before being restored to deformation after being clamped into the target position; for another example, the blocking structure is a deformable elastic sheet, the elastic sheet is deformed when the blocking sheet 41 is assembled, and the blocking sheet 41 is matched with the elastic sheet in a blocking way after the blocking sheet 41 is assembled; for another example, the key hole 21 is a special-shaped hole, and the blocking piece 41 is installed in the key hole 21 and rotated for a certain angle, and then the blocking part is blocked and matched with the blocking structure; as another example, as shown in fig. 2 and 7, the flap 41 is installed in an inclined position, and the posture of the flap 41 is adjusted after installation to be in stop engagement with a stop structure, which will be described in detail later.

The baffle 41 and the key cap 42 are used for being sequentially installed in the key hole 21 and then connected together, and the key cap 42 is in guiding fit with the key hole 21 along the extending direction of the key hole 21. The key cap 42 is in guide fit with the key hole 21, so that the key 4 and the key hole 21 move stably and are not easy to shake.

Specifically, the key cap 42 and the blocking piece 41 may be connected in any feasible manner, for example, in one embodiment, the key cap 42 and the blocking piece 41 are fixedly connected, and the specific connection manner may be adhesion, or snap connection, or fixing the blocking piece 41 and the key cap 42 together through a threaded fastener, or fixing through magnetic adsorption.

In the present utility model, referring to fig. 2, 3 and 4, the key 4 is used for applying pressure to the sealing member 3 and for pressing the pressed member 1 in the housing 2 through the sealing member 3. Since the key 4 is required to have no virtual position and cannot shake, when the key 4 is not pressed, the elastic member applies elastic force to the blocking piece 41 to keep the blocking piece 41 in blocking contact with the blocking surface 213. When the key 4 is pressed, the key 4 applies a force to the elastic member to deform the elastic member, and the stopper 41 is separated from the stopper surface 213. The resilient member may be in any feasible form, for example, in one embodiment, the sealing member 3 forms a resilient member, and the sealing member 3 applies a resilient force to the blocking piece 41 in a direction toward the outer side opening 211 for keeping the blocking piece 41 in blocking contact with the blocking surface 213 when the key 4 is not pressed. In particular, the sealing element 3 may be made of silicone material. In some other embodiments, a resilient return member for applying a resilient force to the blocking piece 41 in a direction toward the outer opening 211 may be disposed in the key hole 21 for retaining the blocking piece 41 in blocking contact with the blocking surface 213 when the key 4 is not pressed. Specifically, the elastic member may be in any feasible form such as a spring, a spring plate, an elastic rubber, and the like.

In one embodiment, referring to fig. 2, the stop structure includes a stop slot 214 on the wall of the key hole 21, a part of the slot wall of the stop slot 214 forms a stop surface 213, and the stop piece 41 has at least one stop portion 411, and the stop portion 411 is configured to be inserted into the stop slot 214 and configured to be in stop engagement with the stop surface 213. By the stop engagement of the stop slot 214 with the stop portion 411 of the stop tab 41, the stability is improved, and the stop portion 411 is not easily disengaged from the stop slot 214.

In particular, the blocking groove 214 may be any type of groove, such as an annular groove or a plurality of rectangular grooves spaced apart in the circumferential direction of the key hole 21, or the like.

In some other embodiments, the blocking structure may be a spring plate in addition to the blocking slot 214; the key cap can also be a bump arranged on the wall of the key hole 21, and in order to avoid interference between the bump and the key cap, an avoidance groove for avoiding the bump should be arranged on the key cap.

To further facilitate the insertion of the blocking piece 41, in one embodiment, referring to fig. 2, the depth of the blocking groove 214 and the width of the groove in the extending direction of the key hole 21 are as follows: when the flap 41 is fitted from the outer opening 211 in an inclined posture, at least one of the stopper portions 411 can be inserted into the stopper groove 214 and can be brought into stopper engagement with the stopper surface 213 after the posture is adjusted. The stopper groove 214 allows the stopper 41 to be fitted in an inclined posture, and the stopper 41 is less likely to be damaged by fitting in the inclined posture than by fitting the stopper 41 in a deformed manner, and the stopper 41 is less required to have an elastic deformability. When a material having no elastic deformability is selected, the blocking piece 41 is less likely to come out of the key hole 21. Based on the above description, the flap 41 of the present utility model may be made of a material having elastic deformability, such as a plastic sheet, a metal sheet having elastic deformability, or the like. Materials without elastic deformability, such as thicker stainless steel sheets, ceramic sheets, etc., may also be used.

Still further, in one embodiment, referring to fig. 3, 5 and 6, the retaining groove 214 includes a retaining section 2141 and a mounting section 2142, the retaining section 2141 and the mounting section 2142 are arranged in the groove width direction, the mounting section 2142 is located at a side of the retaining section 2141 away from the outer side opening 211 and close to the inner side opening 212, and the retaining portion 411 is configured to be in retaining engagement with the retaining surface 213 in the retaining section 2141. The mounting section 2142 is for insertion of the stopper portion 411 when the flap 41 is fitted from the outer side port 211 in an inclined posture, and the groove depth of the mounting section 2142 is larger than that of the stopper section 2141. Since the groove depth of the mounting section 2142 is deep, the baffle 41 can be inserted deep when being obliquely inserted into the baffle groove 214, and the mounting of the baffle 41 is facilitated. Of course, in some other embodiments, the mounting section 2142 may be selected according to practical needs, and the groove depth of the mounting section 2142 may be the same as the groove depth of the stop section 2141, or even slightly smaller than the groove depth of the stop section 2141. In this embodiment, the groove width direction refers to the arrangement direction of two openings of the key hole 21, the groove depth direction is perpendicular to the groove width direction, and the groove bottom surface of the blocking groove 214 faces the center of the key hole 21.

Further, in an embodiment, referring to fig. 3, 5 and 6, a transition section 2143 is further provided between the mounting section 2142 and the stop section 2141, and the groove depth of the transition section 2143 gradually decreases from the mounting section 2142 to the stop section 2141. The provision of the transition section 2143 facilitates the entry of the flap 41 from the mounting section 2142 into the stopper section 2141, and the flap 41 is not easily stuck. In some other embodiments, a 90 degree step surface may also be formed between the mounting segment 2142 and the stop segment 2141.

In one embodiment, referring to fig. 2 and 8, the baffle 41 has a strip shape, and both ends of the baffle 41 in the length direction are stop portions 411. The blocking portion 411 corresponds to at least one blocking slot 214, and the blocking portion 411 is configured to be inserted into the corresponding blocking slot 214 to be in blocking engagement with the blocking surface 213. Referring to fig. 7, when the blocking piece 41 is fitted into the key hole 21 from the outer side port 211 in an inclined posture, the blocking piece 41 is inserted into the corresponding blocking groove 214 after one of the blocking portions 411 is inserted into the corresponding blocking groove 214, and then the posture is adjusted so that the other blocking portion 411 is inserted into the corresponding blocking groove 214. The two ends of the strip-shaped baffle 41 are provided with the baffle parts 411, so that the baffle 41 has better stability when in baffle fit with the baffle surface 213.

Specifically, referring to fig. 1 and 8, the key cap 42 and the baffle 41 are rectangular, and the four corners of the key cap 42 and the four corners of the baffle 41 are chamfered. Correspondingly, the outer aperture of the key hole 21 is rectangular, and the shape of the outer aperture matches that of the key cap 42.

In some other embodiments, only one blocking portion 411 of the blocking piece 41 may be provided, and at this time, since the key cap 42 is in guiding engagement with the key hole 21, the blocking piece 41 cannot be tilted, and even if only one blocking portion 411 is provided, the blocking piece 41 is difficult to separate from the key hole 21. Of course, in some other embodiments, the blocking piece 41 may be triangular, and the blocking portion 411 may be provided with three blocking portions; similarly, in some other embodiments, the shape of the baffle 41 may be set as required, and the number of the stop portions 411 may be adaptively adjusted.

Specifically, in one embodiment, referring to fig. 2 and 6, the number of the blocking grooves 214 is at least one, and the notches of the two blocking grooves 214 of the same pair are opposite, and the two blocking grooves 214 of the same pair respectively correspond to the blocking portions 411 at two ends of the blocking piece 41.

Referring to fig. 2, 3 and 7, when the blocking piece 41 is assembled, the blocking piece 41 is first inserted into the mounting section 2142 of the corresponding blocking slot 214 in an inclined posture, until the blocking portion 411 of the other end of the blocking piece 41 reaches the notch of the corresponding blocking slot 214, then the posture of the blocking piece 41 is adjusted, so that the blocking portions 411 of the two ends of the blocking piece 41 are inserted into the corresponding blocking slots 214, and under the action of the elastic force of the sealing member 3, the blocking portions 411 of the blocking piece 41 are located in the mounting section 2142 of the corresponding blocking slots 214 and are in blocking contact with the blocking surfaces 213 in the corresponding blocking slots 214, so that the blocking piece 41 is mounted. After the baffle 41 is installed, the key cap 42 is fixed on the baffle 41. Since the key cap 42 is in guide engagement with the key hole 21, the blocking piece 41 is not inclined at this time, and is not removed from the key hole 21. The inclination of the present utility model means a state in which the blocking piece 41 is opposite to the key hole 21, and when the blocking piece 41 is inclined, one end of the blocking piece 41 is forward and the other end is backward in the extending direction of the key hole 21, that is, one end of the blocking piece 41 is inserted into the blocking groove 214 first and the other end is backward, and the blocking piece 41 is inserted into the blocking groove 214 after the posture is adjusted.

In some other embodiments, the blocking grooves 214 may be annular grooves, and each blocking portion 411 corresponds to the same blocking groove 214.

To further facilitate the installation of the seal member 3, in one embodiment, referring to fig. 2 and 3, the seal member 3 includes an elastic body 31 connected to the baffle 41 and a skirt 32 disposed on the outer periphery of the elastic body 31, the elastic body 31 passing through the inner opening 212 for pressing the pressed member 1, and the skirt 32 being in sealing engagement with the side of the sealing flange 22 facing the outer opening 211. Specifically, the elastic body 31 is columnar, the skirt 32 is bowl-shaped, and the skirt 32 is connected to the elastic body 31 and surrounds a circle. In the axial direction of the elastic body 31, one end of the skirt 32 is connected to the elastic body 31, and the other end is in contact with the seal flange 22. When the key 4 is depressed, the flap 41 compresses the seal 3 to increase the pressure between the skirt 32 and the sealing flange 22. Specifically, the elastic body 31 and the skirt 32 are both made of silica gel materials.

Further, in order to facilitate the installation of the sealing member 3, in one embodiment, referring to fig. 2 and 3, the sealing member 3 is connected to the blocking piece 41. The retainer 41 is assembled with the seal 3 and then fitted into the key hole 21.

In one embodiment, to enhance the retaining effect, the retaining post 312 is provided with an annular groove into which the retaining plate 41 is retained. One end of the pressing post 311 has a stopper positioning surface 3111 facing the stopper 41 and engaged with the stopper 41. When the baffle 41 is pressed down, the elastic body 31 is driven to move, the skirt 32 is compressed and deformed, and the end part of the pressing column 311 contacts the pressed piece 1, so that the pressed piece 1 is triggered. The clamping column 312 extends out of the baffle 41, and one side of the key cap 42, facing the baffle 41, is provided with an avoidance groove for avoiding the clamping column 312. Referring to fig. 5 and 8, in the present embodiment, the inner opening is a circular opening through which the pressing post 311 passes, and the radius of the clamping post 312 is smaller than the radius of the pressing post 311.

In one embodiment, referring to fig. 2 and 4, the pressed member 1 is a power switch disposed in the housing 2, and the power switch controls the on/off of a circuit between the atomizing heating member and the power source 5. In some other embodiments, the pressed component 1 may be any other component that needs to be pressed, such as a switch on the housing 2 that opens a flip.

In one embodiment, referring to fig. 2, in order to improve the guiding and matching stability of the key 4 and the housing 2, and not to affect the convenience of installing the baffle 41, the thickness of the baffle 41 in the extending direction of the key hole 21 is smaller than that of the key cap in the extending direction of the key hole 21, so that the installation of the baffle 41 is more facilitated when the baffle 41 needs to be obliquely installed into the key hole 21. After the baffle 41 and the key cap 42 are fixedly connected together, the key cap 42 and the shell 2 have better guiding performance, and the key 4 is less prone to shaking. Of course, in some other embodiments, the thickness of the key cap 42 may be the same as the thickness of the baffle 41, and in some special cases, for example, when the baffle 41 is installed in the key hole 21 in other ways than the inclined installation of the baffle 21, the thickness of the key cap 42 may be smaller than the thickness of the baffle 41. In some other embodiments, the blocking piece 41 may also be in guiding engagement with the key hole 21 in the extending direction of the key hole 21.

The extending direction of the key hole 21 described in the present utility model means the arrangement direction of the outer side ports 211 and the inner side ports 212 of the key hole 21. The thickness direction of the baffle 41 coincides with the extending direction of the key hole 21.

In one embodiment, referring to fig. 2, since the key 4 and the sealing member 3 are both installed in the key hole 21, no additional fixing member is required to be added to the housing 2, and the housing 2 is integrally formed. Of course, in other embodiments, the housing 2 may be a split structure to facilitate processing of the housing 2.

The installation process of the key installation structure is as follows:

referring to fig. 2, 3 and 7, the flap 41 is preassembled with the seal 3 and then the flap 41 is inserted obliquely from the outer side opening 211 of the key hole 21. The stop part 411 at one end of the baffle 41 is inserted into the corresponding baffle slot 214, the stop part 411 at the other end of the baffle 41 enters the push button hole 21 to the notch of the corresponding baffle slot 214, at this time, the skirt edge 32 of the sealing element 3 is compressed, the elastic body 31 is inserted into the inner side port 212 of the push button hole 21, and under the auxiliary action of the elastic force of the skirt edge 32, the posture of the baffle 41 is adjusted, so that the stop parts 411 at both ends of the baffle 41 are in the installation section 2142 of the baffle slot 214 and are in stop contact with the stop surface 213 in the baffle slot 214, and the installation of the baffle 41 is completed. The key cap 42 is adhered to the blocking piece 41 by back adhesive, and the installation of the key 4 is completed. Since the key cap 42 is in guide engagement with the key hole 21 with a small gap therebetween, the blocking piece 41 cannot be obliquely withdrawn from the key hole 21. Because the size of the mounting section 2142 in the baffle slot 214 can be precisely machined, the size is less affected by assembly, the matching skirt 32 is always in a deformed state, and the baffle 41 is always applied with elastic force towards the outer opening 211, so that the key 4 has no virtual position and does not shake. The skirt 32 is waterproof after being pressed against the sealing flange 22, and prevents water from entering the housing 2.

In some embodiments of the key installation structure, the key installation structure is the key installation structure described in any one of the above embodiments, and will not be described again.

The foregoing description of the utility model has been presented for purposes of illustration and description, and is not intended to be limiting. Several simple deductions, modifications or substitutions may also be made by a person skilled in the art to which the utility model pertains, based on the idea of the utility model.
