Existing electronic atomizing devices have button switches that are prone to damage due to uncontrollable pressing pressure, resulting in short service life and insufficient reliability.
The design employs a combination of a limiting structure and an elastic element. The limiting structure constrains the movement of the trigger element, while the elastic element provides a rebound force to prevent damage to the switching element due to excessive pressing force. If the elastic element fails, it can be replaced separately to extend the service life of the switching element.
This improves the service life and reliability of the switching elements, avoids the risk of damage caused by excessive pressing force, and extends the overall service life of the device.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomization technology, and in particular to a switch structure and an electronic atomization device. Background Technology
[0002] Existing electronic atomizing devices control atomization through the combination of push-button switches and circuit modules. When a user presses the button, the button presses against a switching element on the circuit board. Because the button's downward travel is unrestricted and the user's pressing force is uncontrollable, excessive pressure can affect the lifespan of the switching element and even cause damage. After releasing the button, the button relies solely on the inherent elastic structure of the switching element (such as a spring) to rebound. Frequent pressing can easily cause fatigue or even failure of this elastic structure. Failure of the elastic structure necessitates replacement of the entire switching element, thus negatively impacting its lifespan. This demonstrates that existing push-button switches suffer from susceptibility to damage (short lifespan) and insufficient reliability. Utility Model Content
[0003] The technical problem to be solved by this application is to provide an improved switch structure and electronic atomization device to improve the service life and reliability of the switch element.
[0004] In some embodiments, a switch structure is provided, comprising a control unit, a trigger, and an elastic element; the control unit includes a switch element having at least two control states; the trigger is movable in a direction close to the switch element and in a direction away from the switch element for triggering the switch element; the trigger is provided with a first limiting structure, the first limiting structure being at least used to constrain the travel of the trigger in the direction close to the switch element; the elastic element is disposed between the control unit and the trigger for providing an elastic force to drive the trigger to move in the direction away from the switch element.
[0005] In some embodiments, the first limiting structure is a limiting groove formed on the trigger.
[0006] In some embodiments, the trigger includes an operating portion and a limiting portion; the operating portion has opposing first and second surfaces, the first surface being disposed toward the switching element; the limiting portion is disposed on the first surface, and the limiting groove is at least partially formed on the limiting portion.
[0007] In some embodiments, the limiting portion includes at least one hook, each hook being bent, and each hook and the first surface together defining the limiting groove.
[0008] In some embodiments, the elastic element includes a main body and a supporting portion; the main body is fixed to the control unit and has opposing third and fourth surfaces, the third surface being disposed toward the trigger; the supporting portion is disposed on the third surface for providing an elastic force to drive the trigger to move in a direction away from the switching element.
[0009] In some embodiments, the main body is provided with a first through hole, the first through hole is adapted to the switching element, and the main body is sleeved on the outer periphery of the switching element through the first through hole.
[0010] In some embodiments, the abutment portion includes at least two protrusions symmetrically arranged on the third surface.
[0011] In some embodiments, the height of the abutment portion protruding relative to the third surface is greater than the height of the switching element protruding relative to the third surface.
[0012] In some embodiments, an electronic atomizing device is provided, comprising a housing and a switching structure as described in any of the above embodiments, wherein the housing has a second through hole, and the switching structure is at least partially disposed at the second through hole; the housing also has a second limiting structure at the edge of the second through hole, wherein the first limiting structure and the second limiting structure cooperate to constrain the travel of the trigger element in a direction close to the switching element.
[0013] In some embodiments, the second limiting structure includes a plurality of protrusions formed on the inner edge of the second through hole.
[0014] According to the switch structure of the above embodiment, since the first limiting structure is used to constrain the travel of the trigger element in the direction close to the switch element, when the trigger element is pressed to its maximum travel, further pressing of the trigger element will no longer apply pressure to the switch element, thus avoiding the risk of damage to the switch element caused by excessive pressing force. Because an additional elastic element is provided between the control unit and the trigger element, the elastic element can provide elastic force to drive the trigger element to move in the direction away from the switch element; that is, the elastic element achieves the rebound of the trigger element. Therefore, it is unnecessary to design an elastic structure on the switch element. If the elastic element fails, only the elastic element needs to be replaced, without affecting the service life of the switch element. The above configuration comprehensively improves the service life and reliability of the switch element. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.
[0029] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.
[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).
[0031] Please see Figure 1 and Figure 2 In some embodiments, an electronic atomizing device is provided, comprising a housing 1 and a switch structure. The housing 1 has a second through hole 10, and the switch structure is at least partially disposed at the second through hole 10. Specifically, the housing 1 encloses a receiving cavity, and the electronic atomizing device further includes an atomizing component 11 and a battery 12 disposed within the receiving cavity. The switch structure includes a control unit. The control unit includes a circuit board 21. A control circuit is disposed on the circuit board 21. The battery 12, the circuit board 21, and the atomizing component 11 are electrically connected. The atomizing component 11 is used to heat and atomize the atomizing matrix to generate an aerosol when energized. The control circuit can control the on / off state of the atomizing component 11, the atomization power, etc.
[0032] Please see Figures 3 to 5In some embodiments, a switch structure is provided that can be applied to an electronic atomizing device. The switch structure includes a control unit, a trigger element 3, and a spring element 4. The control unit includes a circuit board 21 and a switch element 22 for controlling the circuit's on / off state. Specifically, the switch element 22 is connected to the circuit board 21 and controls the circuit on / off state of the control circuit on the circuit board 21. In one embodiment, when the switch element 22 is not triggered, the circuit module on the control circuit used to control the atomization switch of the atomizing component 11 is not connected, and the atomizing component 11 does not work. When the switch element 22 is triggered, the circuit module on the control circuit used to control the atomization switch of the atomizing component 11 is connected, and the atomizing component 11 is energized and enters the working mode.
[0033] In another embodiment, the switching element 22 is used to perform at least one function of the control circuit. For example, when the switching element 22 is triggered, the control circuit outputs a power supply voltage in a high-power mode; when the switching element 22 is triggered again, the control circuit outputs a power supply voltage in a low-power mode, thereby providing a power switching function for the electronic atomizing device.
[0034] In addition to switching the power supply voltage on and off and switching between high and low voltages, the control circuit can also integrate other control functions, such as child lock function, light switching function, vibration feedback function, etc.
[0035] The trigger 3 is a component operated by hand. The trigger 3 is exposed at the second through-hole 10 and covers the switching element 22. The trigger 3 is movable in directions approaching and away from the switching element 22 to trigger the switching element 22. In some embodiments, the switching element 22 may be a mechanical switching element, such as a tactile switch. The switching element 22 is triggered when the trigger 3 moves in the direction approaching the switching element 22 until it contacts the switching element 22. Alternatively, in other embodiments, the switching element 22 may be a Hall switch, and the trigger 3 has a magnet. The switching element 22 is triggered when the trigger 3 moves in the direction approaching the switching element 22 until the distance between it and the switching element 22 is less than a certain threshold. The trigger 3 is provided with a first limiting structure, which at least restricts the travel of the trigger 3 in the direction approaching the switching element 22. That is, in some embodiments, the first limiting structure can be used to constrain only the travel of the trigger 3 in the direction close to the switching element 22; or, in other embodiments, the first limiting structure can be used to constrain both the travel of the trigger 3 in the direction close to the switching element 22 and the travel of the trigger 3 in the direction away from the switching element 22.
[0036] An elastic element 4, disposed between the control unit and the trigger element 3, provides an elastic force to drive the trigger element 3 to move in a direction away from the switching element 22. Specifically, the elastic element 4 is a component with elastic deformation capability, such as a silicone component, a rubber component, or a spring. When the trigger element 3 moves in a direction closer to the switching element 22 under the action of an external force (e.g., a pressing force applied to the trigger element 3 by a person's hand), pressure is applied to the elastic element 4, and the elastic element 4 is compressed. When the external force on the trigger element 3 disappears, the elastic element 4 provides an elastic force to rebound the trigger element 3 in a direction away from the switching element 22, causing the trigger element 3 to return to its initial position.
[0037] In summary, since the first limiting structure at least constrains the travel of the trigger 3 in the direction close to the switching element 22, when the trigger 3 is pressed to its maximum travel, further pressing of the trigger 3 will no longer apply pressure to the switching element 22, thus avoiding the risk of damage to the switching element 22 due to excessive pressing force. Because an additional elastic element 4 is provided between the control unit and the trigger 3, the elastic element 4 provides elastic force to drive the trigger 3 in the direction away from the switching element 22, that is, the rebound of the trigger 3 is achieved through the elastic element 4. Therefore, it is unnecessary to design an elastic structure on the switching element 22. If the elastic element 4 fails, only the elastic element 4 needs to be replaced, without affecting the service life of the switching element 22. The above configuration comprehensively improves the service life and reliability of the switching element 22.
[0038] Please see Figure 4 and Figure 5 In some embodiments, the housing 1 is further provided with a second limiting structure at the edge of the second through hole 10. The first limiting structure and the second limiting structure cooperate to constrain the travel of the trigger 3 in the direction approaching the switching element 22. Specifically, the first limiting structure and the second limiting structure are interlocked. Furthermore, there is a gap between the first limiting structure and the second limiting structure in the direction in which the trigger 3 and the switching element 22 approach each other, and this gap forms the constraint travel of the trigger 3 and the switching element 22 approaching each other.
[0039] Please see Figure 6 and Figure 7In some embodiments, the first limiting structure is a limiting groove 31 formed on the trigger 3. Correspondingly, the second limiting structure includes a plurality of protrusions 13 formed on the inner edge of the second through hole 10. Specifically, the number of limiting grooves 31 is not limited, and can be one or more; the number of protrusions 13 is not limited, and can be one or more. The limiting grooves 31 and protrusions 13 can be fitted in a one-to-one correspondence. Furthermore, the size of the limiting groove 31 is slightly larger than the size of the protrusions 13, and the protrusions 13 can move a certain distance along the limiting groove 31. The relative movement between the protrusions 13 and the limiting groove 31 is also the constraint travel between the trigger 3 and the switching element 22. As the trigger 3 moves towards the switching element 22, the protrusion 13 moves along the limiting groove 31. When the protrusion 13 reaches its maximum stroke along the limiting groove 31, the inner wall of one end of the protrusion 13 and the limiting groove 31 abuts, and the trigger 3 can no longer move towards the switching element 22. Therefore, the stroke of the trigger 3 in the direction of moving towards the switching element 22 can be constrained. Of course, in some other embodiments, the first limiting structure can be a protrusion structure and the second limiting structure can be a groove structure, as long as the two can cooperate to construct the constrained stroke.
[0040] Please see Figure 5 , Figure 7 and Figure 8 In some embodiments, the trigger 3 includes an operating portion 32 and a limiting portion 33. The operating portion 32 is operated by touch. The operating portion 32 has a first surface 321 and a second surface 322 facing each other. The first surface 321 faces the switching element 22. The second surface 322 faces away from the switching element 22 and is exposed at the second through hole 10 for direct touch operation by touch. The limiting portion 33 is disposed on the first surface 321, and a limiting groove 31 is at least partially formed on the limiting portion 33. That is, the limiting groove 31 may be entirely formed on the limiting portion 33; or, a portion of the limiting groove 31 may be formed on the limiting portion 33, and the other portion may be formed at other positions on the trigger 3.
[0041] Furthermore, such as Figure 5 , Figure 7 and Figure 8As shown, in some embodiments, the limiting portion 33 includes at least one hook 331, each hook 331 being bent, and each hook 331 and the first surface 321 jointly defining a limiting groove 31. Specifically, each hook 331 is L-shaped. Each hook 331 is connected to the first surface 321 at a position near the outer contour edge of the first surface 321, and the connection between the hook 331 and the first surface 321 is separated from the outer contour edge of the first surface 321 by a certain distance. The trigger member 3 has a central axis X passing through its centroid. Each hook 331 has an L-shaped outer wall surface 332 facing away from the central axis X. The L-shaped outer wall surface 332 and the first surface 321 jointly define the limiting groove 31. The opening of the limiting groove 31 faces away from the central axis X.
[0042] The cooperation between the limiting part 33 and the limiting groove 31 can simultaneously constrain the travel of the trigger 3 in the direction close to the switching element 22 and in the direction away from the switching element 22.
[0043] like Figure 5 As shown, in some embodiments, the elastic member 4 includes a main body 41 and a supporting portion 42. The main body 41 is fixed to the control unit. Specifically, the main body 41 is fixed to the circuit board 21. The main body 41 has opposing third surfaces 411 and fourth surfaces 412, with the third surface 411 facing the trigger member 3. The supporting portion 42 is disposed on the third surface 411 and is used to provide an elastic force to drive the trigger member 3 to move away from the switching element 22. That is, the elastic member 4 is fixed to the circuit board 21 by the main body 41. The supporting portion 42 serves as the part that abuts against the trigger member 3. At least the supporting portion 42 is made of a material with elastic deformation capability. The main body 41 and the supporting portion 42 can be an integrally molded structure. For example, the main body 41 and the supporting portion 42 can be an integrally molded silicone part. Alternatively, the supporting portion 42 can be a silicone part, and the main body 41 can be a plastic part.
[0044] Furthermore, such as Figure 5 As shown, in some embodiments, the main body 41 is provided with a first through hole 410, which is adapted to the switching element 22. That is, the shape and size of the first through hole 410 and the switching element 22 are approximately the same, or the size of the first through hole 410 is slightly smaller than the size of the switching element 22. The main body 41 is sleeved on the outer periphery of the switching element 22 through the first through hole 410, thereby fixing the position of the main body 41 on the circuit board 21.
[0045] Furthermore, such as Figure 5As shown, in some embodiments, the abutment 42 may include at least two protrusions 421 symmetrically arranged on the third surface 411. When the trigger 3 moves in the direction close to the switching element 22, it can simultaneously abut against each of the protrusions 421. Since the protrusions 421 are symmetrically arranged, the elastic force provided by the protrusions 421 to the trigger 3 is also symmetrically balanced, which is beneficial for providing a uniform rebound force to the trigger 3.
[0046] Furthermore, such as Figure 3 As shown, in some embodiments, the height of the abutment portion 42 relative to the protrusion 13 of the third surface 411 is greater than the height of the switch element 22 relative to the protrusion 13 of the third surface 411. Therefore, when a hand presses the trigger 3, the trigger 3 moves towards the switch element 22. The trigger 3 first contacts the abutment portion 42, and only after overcoming a certain resistance from the abutment portion 42 does it contact the switch element 22. Thus, the abutment portion 42 provides a buffering force before the trigger 3 contacts the switch element 22, thereby reducing the risk of damaging the switch element 22 if the pressing force is too great.
[0047] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the concept of this invention.
