Description

Technical Field

[0001] The utility model belongs to the technical field of buckle structures, in particular to a locking structure and an aroma diffuser. Background Art

[0002] In an aroma diffuser, a battery is commonly used as a power source. The battery is installed in the battery compartment of the aroma diffuser, and a dry battery is locked in the battery compartment by a battery compartment cover plate that is buckled with the housing. Generally, at both ends of the existing battery compartment cover plate, hooks are used to fix it on the battery compartment. This connection method may be too tight to open and remove the battery, or too loose, and the battery compartment cover plate is likely to fall off. Especially when the remote control drops to the ground, the hooks of the battery compartment cover plate are easily loosened due to impact vibration, resulting in the battery compartment cover plate falling off and the battery popping out of the battery compartment, which brings trouble to the user.

[0003] Moreover, the hooks on the existing battery cover plate are clamped with the slots of the battery compartment by using their own elasticity. In this way, every time the battery compartment is opened, the hooks will be squeezed and deformed. The hooks are prone to mechanical fatigue during long-term use, resulting in the fracture of the hooks; or the hooks are subjected to a large external force, and the hooks are easily broken, resulting in poor use stability of the battery cover plate. Therefore, there is still room for improvement in the existing hooks on the battery cover plate. Summary of the Invention

[0042] Unless otherwise specified or defined, the "first, second..." used herein is only for differentiating names and does not represent a specific quantity or order.

[0043] Unless otherwise specified or defined, the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0044] It should be noted that when an element is considered to be "fixed to" another element, it can be directly fixed to the other element or there can be an intermediate element; when an element is considered to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time; when an element is considered to be "mounted on" another element, it can be directly mounted on the other element or there can be an intermediate element at the same time. When an element is considered to be "provided in" another element, it can be directly provided in the other element or there can be an intermediate element at the same time.

[0045] The present utility model provides a buckle structure 50, as Figures 1 to 6As shown in the figure, it includes: a support body 55, a battery cover plate 52, and a locking component 51. A battery compartment 551 is formed inside the support body 55, and the support body 55 has a first card slot 555; the first end of the battery cover plate 52 is fitted with the support body 55, the battery cover plate 52 is arranged at the opening of the battery compartment 551, and the second end of the battery cover plate 52 has an installation opening 520; the locking component 51 includes a locking member 510 and a first clamping block 5121. The first clamping block 5121 is installed on the locking member 510, the locking member 510 is arranged at the installation opening 520, and the locking member 510 is slidably fitted with the battery cover plate 52; the locking member 510 has a first moving position and a second moving position at the installation opening 520. In the first moving position, the first clamping block 5121 is clamped with the first card slot 555; in the second moving position, the first clamping block 5121 is separated from the first card slot 555. Specifically, during assembly, the locking member 510 is installed at the installation opening 520 of the battery cover plate 52, so that the locking member 510 is slidably fitted with the battery cover plate 52 at the installation opening 520. The battery 53 is placed in the battery compartment 551, and then the first end of the battery cover plate 52 is engaged with the support body 55. The second end of the battery cover plate 52 slides the locking member 510 to move the locking member 510 to the first moving position. The first clamping block 5121 on the locking member 510 is clamped with the first card slot 555, and the battery cover plate 52 is locked with the support body 55 through the first clamping block 5121, realizing that the battery cover plate 52 completely seals the opening of the battery compartment 551. When the locking member 510 slides to the second moving position, the first clamping block 5121 is separated from the first card slot 555, and the battery cover plate 52 is separated from the support body 55 by moving the first clamping block 5121, so as to remove the battery cover plate 52 and realize opening the battery compartment 551.

[0046] The operation mode of the locking structure 50 is relative to the existing hook. When the locking structure 50 is used, only the locking member 510 needs to be slid to open or close the battery compartment 551, without applying an external force to squeeze the locking member 510. The locking member 510 will not deform during use, avoiding mechanical fatigue of the locking member 510 and improving the stability of the locking member 510 during use. Moreover, in terms of use stability, the friction resistance coefficient between the locking member 510 and the battery cover plate 52 is set in advance. When the locking structure 50 drops to the ground and the battery cover plate 52 is impacted and vibrated, the vibration cannot drive the battery cover plate 52 to slide, so it is not easy to cause the battery cover plate 52 to fall off, and the battery 53 is always stably located in the battery compartment 551.

[0047] In some embodiments, such as Figure 6 and Figure 8As shown, the locking member 510 includes a first support plate 511 and a second support plate 512. The first support plate 511 has an L-shaped structure. The first clamping block 5121 is installed at the first end of the first support plate 511. The second end of the first support plate 511 has a first limiting block 514. The inner wall of the battery cover plate 52 has a second limiting block 521 and a third limiting block 522. When the locking member 510 is in the first moving position, the first limiting block 514 abuts against the second limiting block 521. When the locking member 510 is in the second moving position, the first limiting block 514 abuts against the third limiting block 522. Specifically, when the second support plate 512 is toggled to move, the second support plate 512 drives the first support plate 511 to move, thereby driving the first limiting block 514 to move. When the second support plate 512 moves to the first moving position, the first limiting block 514 abuts against the second limiting block 521. The second limiting block 521 is used to limit the movement of the locking member 510. At this time, the first clamping block 5121 is clamped with the first clamping groove 555 to lock the battery cover plate 52. When the second support plate 512 moves to the second moving position, the first limiting block 514 is separated from the second limiting block 521. The first clamping block 5121 moves out of the first clamping groove 555. The first limiting block 514 moves towards the third limiting block 522. The guiding inclined surface of the first limiting block 514 is slidably matched with the third limiting block 522. The first limiting block 514 moves to the upper end of the third limiting block 522, and the lower end of the first limiting block 514 abuts against the third limiting block 522. Without external force, the third limiting block 522 is used to limit the downward movement of the first limiting block 514 to prevent the locking member 510 from automatically sliding to the first moving position, further improving the stability of the locking member 510 during use.

[0048] In some embodiments, as Figure 7 and Figure 8 shown, there is a first limiting groove 5122 between the first clamping block 5121 and the first support plate 511. The support main body 55 has a notch and a limiting rod 556. The notch corresponds to the installation opening 520. The limiting rod 556 is installed at the notch, and the notch forms a receiving groove 554 and a first clamping groove 555. At least a part of the first support plate 511 is disposed in the receiving groove 554. When the locking member 510 is in the first moving position, at least a part of the limiting rod 556 cooperates with the first limiting groove 5122. Specifically, when the locking member 510 moves to the first moving position, the first clamping block 5121 is clamped with the first clamping groove 555. The first limiting groove 5122 moves with the first support plate 511, so that the inner wall of the first support plate 511 abuts against the limiting rod 556, further restricting the movement of the first clamping block 5121 in the first clamping groove 555 and further improving the stability of the cooperation between the first clamping block 5121 and the first clamping groove 555.

[0049] Preferably, as Figure 8As shown, the latch assembly 51 further has a shift block 513. The shift block 513 is installed on the second support plate 512, and at least part of the shift block 513 protrudes from the outer surface of the support body 55; the shift block 513 is opposite to and spaced from the first latch block 5121. Specifically, during use, the finger abuts against the shift block 513 on the outer surface of the support body 55, and the finger pushes the shift block 513 to move. The shift block 513 drives the second support plate 512 to move, improving the convenience of moving the locking member 510.

[0050] In some embodiments, as Figure 8 shown, the cross-section of the second support plate 512 is T-shaped. A guide groove 515 is formed between the first support plate 511 and the second support plate 512. The battery cover plate 52 has a guide block 523 that slidably cooperates with the guide groove 515. The guide block 523 is provided at the mounting opening 520. Specifically, the guide block 523 is provided at the mounting opening 520 and slidably cooperates with the guide groove 515 of the locking member 510, so that the locking member 510 can be restricted at the mounting opening 520, improving the stability of the locking member 510 sliding at the mounting opening 520. During use, by pushing the shift block 513 to move, the first support plate 511 is driven to move.

[0051] In some embodiments, as Figure 3 and Figure 9 shown, the inner side of the battery cover plate 52 has a positioning block 524, and the support body 55 has a positioning groove 557 corresponding to the positioning block 524. The positioning block 524 is snap-fitted with the positioning groove 557. Specifically, when the battery cover plate 52 cooperates with the support body 55, the positioning block 524 corresponds to the positioning groove 557, facilitating the positioning and assembly of the battery cover plate 52 on the support body 55; moreover, after the positioning block 524 cooperates with the positioning groove 557, the stability of the battery cover plate 52 and the support body 55 after cooperation is also improved. In addition, the battery cover plate 52 has a second latch block 527, and the support body 55 has a second slot. The first end of the battery cover plate 52 is snap-fitted with the second slot of the support body 55 through the second latch block 527.

[0052] Preferably, as Figure 7 and Figure 9As shown, the support body 55 has a mounting hole 558, the battery cover plate 52 has a through hole 526, and the latch assembly 51 further has a fastener 525. The first end of the fastener 525 passes through the through hole 526 so that the first end of the fastener 525 is threadedly connected to the mounting hole 558, and the second end of the fastener 525 abuts against the battery cover plate 52. Specifically, when the battery compartment 551 contains a rechargeable battery 53, the locking member 510 moves to the first moving position, and the battery cover plate 52 is locked to the support body 55; then the fastener 525 passes through the through hole 526 and is connected to the mounting hole 558 of the support body 55, so that the battery cover plate 52 is locked to the support body 55. Without using tools to rotate the fastener 525, the fastener 525 cannot be removed from the mounting hole 558, which can further improve the stability of the connection between the battery cover plate 52 and the support body 55.

[0053] Preferably, as Figures 3 to 5 shown, the support body 55 further has a first conductive elastic member 552 and a second conductive elastic member 553. The first conductive elastic member 552 is disposed at the first end of the battery compartment 551, and the second conductive elastic member 553 is disposed at the second end of the battery compartment 551. The first conductive elastic member 552 and the second conductive elastic member 553 are disposed opposite to each other; the battery compartment 551 is used to accommodate the battery 53, and both ends of the battery 53 are respectively used to abut against the first conductive elastic member 552 and the second conductive elastic member 553, and the positive and negative electrodes of the battery 53 are electrically connected to the first conductive elastic member 552 and the second conductive elastic member 553 respectively. Specifically, the battery 53 is installed in the battery compartment 551 so that both ends of the battery 53 respectively abut against the first conductive elastic member 552 and the second conductive elastic member 553. Both ends of the battery 53 respectively squeeze the first conductive elastic member 552 and the second conductive elastic member 553, and the first conductive elastic member 552 and the second conductive elastic member 553 generate reaction forces to squeeze the battery 53, which can improve the stability of the connection between the battery 53 and the first conductive elastic member 552 and the second conductive elastic member 553 respectively, avoid the phenomenon of looseness between the battery 53 and the first conductive elastic member 552 and the second conductive elastic member 553, and improve the electrical conductivity between the battery 53 and the first conductive elastic member 552 and the second conductive elastic member 553.

[0054] The present utility model further provides an aroma diffuser 100, as Figures 1 to 3As shown in the figure, it includes a first housing 10, a fastening member 30, a second housing 20, an air pump 70, an atomization assembly 60, and the buckle structure 50 as described above. The first end of the first housing 10 is rotatably connected to the first end of the second housing 20, and the second end of the first housing 10 is snap-fitted with the second end of the second housing 20 through the fastening member 30. An installation cavity is formed between the first housing 10 and the second housing 20. The support body 55 of the buckle assembly 51 is installed in the installation cavity and divides the installation cavity into a first chamber and a second chamber. The air pump 70 is installed in the first chamber, and the atomization assembly 60 is installed in the second chamber. The air outlet of the air pump 70 is connected to the atomization assembly 60. Specifically, by installing the support body 55 in the installation cavity, the air pump 70 and the atomization assembly 60 are separated, which is convenient for removing the atomization assembly 60 after opening the first housing 10. The first housing 10 and the second housing 20 are snap-fitted. When the first housing 10 and the second housing 20 are opened, the atomization assembly 60 and the buckle structure 50 are exposed, and the atomization assembly 60 can be removed from the buckle structure 50 for replacing the essential oil in the atomization assembly 60. At the same time, the buckle structure 50 can also be opened to replace the battery 53 in the battery compartment 551. And the air pump 70 is installed in the first chamber, and generally does not need to be taken out under normal circumstances.

[0055] In some embodiments, as Figure 4 shown, the fragrance diffuser 100 further has a PCB circuit board 40, a charging interface member 54, and a battery 53.

Specifically, when the battery 53 in the battery compartment 551 is a rechargeable battery 53 and needs to be charged, the USB charging cable is inserted into the charging interface member 54, and the USB charging cable charges the battery 53 through the PCB circuit board 40. This PCB circuit board 40 is also electrically connected to the air pump 70. The PCB circuit board 40 has a control circuit. The battery 53 provides electrical energy for the air pump 70. The air pump 70 is connected to the atomization core of the atomization assembly 60 through an air pipe 701. The control circuit controls the air pump 70 to start, so that the air pump 70 generates high-pressure gas acting on the atomization core.

[0056] It should be noted that in this buckle structure 50, by arranging the locking member 510 at the installation opening 520 of the battery cover plate 52, the locking member 510 is slidably engaged with the battery cover plate 52. When the locking member 510 slides to a preset position, the first latch 5121 is engaged with the first card slot 555. In other buckle structures 50, by using the sliding of the above-mentioned locking member 510 to engage the latch with the card slot to realize the structure of locking the battery cover plate 52 and the support body 55, all are within the protection scope of this application.
