DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0046] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0047] The sealing structure provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0048] First, the following noun concepts are described:

[0049] Personal care equipment: refers to equipment that can provide care functions to users using care products (such as skin care products, toothpaste, detergents, hair treatment agents, etc.), such as skin care devices, electric toothbrushes, facial cleansers, electric razors, hair combs and other equipment, which include a body and a container.

[0050] The body is a device part specifically used to use care products to achieve care functions. Corresponding to different types of personal care devices, the body may include different functional devices. For example, when the personal care device is a massager that automatically applies care products, the body may include an electric massage head for applying care products. When the personal care device is an electric toothbrush that can automatically replenish toothpaste, the body may include an electric toothbrush for brushing teeth (which may include a toothbrush head, a control module that controls the operation of the toothbrush head, a drive module, etc.). The embodiments of the present application do not limit the specific structural design of the body and the specific device components included.

[0051] The container is a device part specifically used to store care products. Different care products can be stored in the container corresponding to different types of personal care devices. For example, when the personal care device is a massager that automatically applies care products, facial creams, lotions, etc. can be stored in the container. When the personal care device is an electric toothbrush that can automatically replenish toothpaste, toothpaste can be stored in the container. The embodiments of the present application do not limit the specific structural design of the container and the categories of care products stored.

[0052] In the embodiment of the present application, the buckle structure provided is applied to the disassembly and assembly between the body and the container in the personal care device. According to the actual situation, the personal care device can include any number of bodies and containers, such as one body with one container for storing care products, one body with multiple containers for storing different types of care products, and one container with multiple bodies with different functions. It can be flexibly set according to specific application requirements. Accordingly, no matter which body and container are matched, the buckle structure provided in the embodiment of the present application can be set for the disassembly and assembly between each set of bodies and containers. It can be understood that the embodiment of the present application does not limit the type of personal care equipment, the number of bodies and containers included, and the number of buckle structures used, and can be flexibly set according to actual needs.

[0053] See also Figure 1 and Figure 2 , the figure shows a personal protection device, including a body 01 and a container 02, and the body 01 and the container 02 are disassembled and assembled through a snap-fit ​​structure 03.

[0054] See also Figures 3 to 13 The embodiment of the present application provides a buckle structure, including: a first buckle 1, a second buckle 2, a pushing member 3, a linkage member and an elastic member 4; the pushing member 3 is connected to the first buckle 1 through the linkage member, and the pushing member 3 is connected to the second buckle 2; the pushing member 3 is used to drive the second buckle 2 and the first buckle 1 to move away from each other through the linkage member when a force is applied to the pushing member 3; the elastic member 4 is used to release the elastic force when the force disappears, so that the pushing member 3 drives the second buckle 2 and the first buckle 1 to move towards each other through the linkage member.

[0055] In the embodiment of the present application, when the pushing member 3 is applied with a force, the pushing member 3 drives the second fastener 2 and the first fastener 1 through the linkage member, so that the first fastener 1 and the second fastener 2 move away from each other, so that the two fasteners are opened, and then the body 01 and the container 02 of the personal protection device can be unlocked. When the force is canceled or the force disappears, the device to be locked, such as a container, is inserted at this time. Under the elastic force of the elastic member 4, the pushing member 3 drives the second fastener 2 and the first fastener 1 through the linkage member, so that the second fastener 1 and the second fastener 2 move away from each other, so that the two fasteners are opened, and then the body 01 and the container 02 of the personal protection device are unlocked. A latch 1 and a second latch 2 move toward each other, and the clamping function is realized by the movement of the two latches, thereby realizing the locking between the body 01 and the container 02 of the personal protection device; the latch structure provided in the embodiment of the present application simplifies the structural design, and the body 01 and the container 02 of the personal protection device can be unlocked by applying a force to the pushing member, or the container 02 can be inserted at this time and the force can be canceled at the same time, so as to realize the locking of the body 01 and the container 02 of the personal protection device, simplify the operation, and improve the convenience of disassembly and assembly of the personal protection device.

[0056] It should be further explained that, without applying force to the pusher 3 , the container 02 of the personal protection device can also be directly inserted into the body 01 , so that the container 02 and the body 01 are installed (ie locked) together.

[0057] In an optional embodiment, if Figure 4 As shown, the first locking member 1 is provided with a first guide surface 11 on a side facing the container 02 , and the second locking member 2 is provided with a second guide surface 21 on a side facing the container 02 ; both the first guide surface 11 and the second guide surface 21 are inclined surfaces.

[0058] In the embodiment of the present application, the first guide surface 11 and the second guide surface 21 are respectively provided on the side of the first fastener 1 and the second fastener 2 facing the device to be clamped (such as the container 02), that is, the first guide surface 11 is provided on the side of the first fastener 1 facing the container 02, and the second guide surface 21 is provided on the side of the second fastener 2 facing the container 02; the first guide surface 11 and the second guide surface 21 are inclined surfaces, and the inclined surface setting method is adopted, especially the inclined setting from the bottom to the top with the direction of the container 02 as the bottom, which plays a guiding role on the one hand, and on the other hand, it is also convenient for the device to be clamped (such as the container 02) to be inserted into the fuselage 01, so as to achieve the locking of the container 02 and the fuselage 01. In a specific scenario, the container 02 is directly inserted into the snap structure 03 of the fuselage 01. During the insertion process of the snap structure 03, the container 02 first abuts against the first guide surface 11 and the second guide surface 21 of the first snap member 1 and the second snap member 2, and then pushes the first snap member 1 and the second snap member 2 to move away from each other until the first snap member 1 and the second snap member 2 are adapted and connected to the connecting structure on the container 02. The elastic member 4 can also generate a rebound force in this process, so that the first snap member 1 and the second snap member are more stably locked together with the snap connection portion 7 of the container 02.

[0059] It is understandable that the force acting on the pusher can be directly applied to the pusher by the user, for example, the user presses the pusher by hand, or it can be applied to the pusher by other device components, for example, the user presses a disassembly control button on the device, and a control instruction is generated accordingly, and the control instruction controls other components to press the pusher. The embodiment of the present application does not limit the implementation method of applying the force to the pusher.

[0060] In an optional embodiment, in combination Figure 3 , Figure 6 , Fig.10 , Fig.11 The linkage member includes a lever portion 5 and a support portion 6, and the lever portion 5 is connected to the support portion 6; the linkage member is used to limit the moving direction of the first buckle 1 and the second buckle 2.

[0061] In the embodiment of the present application, the linkage member is specifically designed with a lever structure. The lever portion 5 realizes the linkage of the pushing member 3 with the first fastener 1 through the lever principle. The support portion 6 is used to provide fixed support for the fulcrum of the lever portion 5. The combination of the support portion 6 and the lever portion 5 further realizes the limitation of the moving direction of the first fastener 1 and the second fastener 2.

[0062] In an optional embodiment, if Figure 5As shown, the pusher 3 includes a force-bearing portion 31, a body 32, and a connecting portion 33; the body 32 is connected to the force-bearing portion 31 and the connecting portion 33 respectively, and the connecting portion 33 is connected to the second clip 2; the force-bearing portion 31 is used to drive the body 32, the connecting portion 33, and the second clip 2 to move in the opposite direction of the first clip 1 when a force is applied. Optionally, the force-bearing portion 31, the body 32, and the connecting portion 33 can be integrally formed, and when the user pushes the force-bearing portion 31, the force-bearing portion 31 moves together with the body 32 and the connecting portion 33, thereby driving the second clip 2 connected to the connecting portion 33 to move.

[0063] In the embodiment of the present application, the pusher 3 includes a force-bearing portion 31 for receiving a force, which can be specifically designed as a button or key or other component that can be applied with a force by a user and is visible or exposed on the outer side of the body 01 of the personal protection device. When a force is applied to the force-bearing portion 31, it drives the second fastener 2 to move and the first fastener 1 to move through the linkage member. In this way, when the force-bearing portion 31 is acted upon by an external force, the force-bearing portion 31, the body 32, the connecting portion 33, and the second fastener 2 move synchronously under the push of the external force.

[0064] It should be noted that the embodiment of the present application does not limit the specific shape of the body 32, as long as it can achieve the transmission of force from the force-bearing portion 31 to the connecting portion 33. Figure 5 In the scenario shown in the figure, the body 32 adopts an annular structure. This is because in actual application scenarios, the buckle structure generally clamps the structural components of the device when working. Therefore, the body 32 can be adaptively designed to be the same shape as the clamped structural component, and is not limited to a circle. It can also be a square or irregular shape. For example, when the clamped device is square, the shape of the body 32 can adopt a square structure. This design can realize that the pusher 3 is set on the structural component of the clamped device, while realizing the buckle structure function, saving the internal space of the device. Of course, the body 32 can also be designed to be a different shape from the structural component of the clamped device, which can be flexibly adjusted according to the actual application scenario requirements.

[0065] In an optional embodiment, if Figure 6 As shown, the lever portion 5 includes a lever body 50, a first connecting member 51 and a second connecting member 52 arranged on the lever body 50, and a fulcrum 53 arranged on the lever body 50, and the fulcrum 53 is located between the first connecting member 51 and the second connecting member 52; the body 32 is connected to the first connecting member 51, and the second connecting member 52 is connected to the first buckle 1.

[0066] In the embodiment of the present application, a lever structure design is adopted, wherein the first connecting member 51 and the second connecting member 52 located on both sides of the fulcrum 53 of the lever body 50 are respectively connected to the body 32 of the pushing member 3 and the first fastener 1, so that when the pushing member 3 moves under the action of an external force, the first connecting member 51 can be driven to move synchronously through the body 32, and under the action of the lever principle, the second connecting member 52 will move in the opposite direction of the first connecting member 51, and synchronously drive the first fastener 1 to move in the opposite direction of the first connecting member 51, and finally realize the first fastener. 1 and the second fastener 2 move away from each other to unlock the clamping device, or the device to be clamped is inserted at this time, and when the force is withdrawn or the force disappears, the pushing member 3 drives the first connecting member 51 to move back synchronously through the main body 32 under the action of the elastic member 4. Under the action of the lever principle, the second connecting member 52 moves in the opposite direction of the first connecting member 51, and synchronously drives the first fastener 1 to move in the opposite direction of the first connecting member 51, and finally the first fastener 1 and the second fastener 2 are close to each other, thereby locking the device to be clamped.

[0067] The lever structure design can realize that under the action of an external force in one direction, the first buckle 1 and the second buckle 2 are controlled to move in opposite directions respectively, and the buckle structure can unlock and lock the personal protection device by simple operation.

[0068] The connection between the connecting part of the lever and other components is mainly due to the fact that the moving trajectory of the lever is an arc during operation, while the moving trajectory of other components is a straight line during operation. In order to combine the movements of the two, the lever part 5 and the pushing member 3 are connected, and the lever part 5 and the snap-fit ​​member are connected. In this way, during the specific working process, the lever and the pushing member 3 and the first snap-fit ​​member 1 can achieve a certain relative movement by relying on the rotation connection of the fulcrum 53, thereby ensuring that the movement rules of the components are correct.

[0069] It should be noted that the lever portion 5 is connected to the pushing member 3 through the first connecting member 51. When the pushing member 3 drives the main body 32 of the force-bearing portion 31 to move forward, it also drives the first connecting member 51 connected to the fourth connecting member 321 of the force-bearing portion 31 to move together. At this time, the lever body 50 rotates relative to the first connecting member 51 and moves in the same direction, that is, at this time, the lever body 50 is rotationally connected to the first connecting member 51 and even the pushing member 3; and the fulcrum 53 is connected to the third connecting member 620, and the fulcrum 53 plays a supporting role. When the pushing member 3 is pushed or the force on the pushing member 3 is withdrawn, parts of the lever body 50 at both ends of the fulcrum 53 move in opposite directions. At this time, the fulcrum 53 rotates relative to the third connecting member 620, that is, the fulcrum 53 is rotationally connected to the third connecting member 620.

[0070] In an alternative embodiment, see Fig.10The support portion 6 includes a base 61, a support frame 62 fixed above the base 61, and the support frame 62 carries the main body 32; a third connecting member 620 is arranged on the support frame 62, and the fulcrum 53 is rotatably connected to the third connecting member 620. The specific implementation method of the rotational connection can be: a connecting shaft is arranged on the third connecting member 620, and an axial hole is arranged on the fulcrum 53, or an axial hole is arranged on the third connecting member 620, and a connecting shaft is arranged on the fulcrum 53.

[0071] In the embodiment of the present application, the function of the support frame 62 is to support the main body 32 and assist the lever part 5 in operation, wherein the third connecting member 620 arranged on the support frame 62 is connected to the fulcrum 53, providing a fixed supporting position for the lever part 5, and being able to satisfy the rotation of the lever part 5 around the fulcrum 53, that is, satisfying the movement of the two ends of the lever part 5 in different directions around the fulcrum.

[0072] Considering that in actual application scenarios, the buckle structure generally clamps the structural components of the device when working, and the support frame 62, as a component that carries the body 32, can be designed to be the same shape as the structural components of the clamped device, such as the circle shown in the figure, but of course it is not limited to the circle, and can also be square or irregular. This design can save space inside the device while realizing the function of the buckle structure. Of course, the support frame 62 can also be designed to be a different shape from the clamped structural component, which can be flexibly adjusted according to the actual application scenario requirements.

[0073] In an alternative embodiment, see Fig.10 A connecting frame 610 is also provided on the base 61. Fig.12 As shown, the connecting frame 610 is disposed around the body 32 to protect the body 32 .

[0074] In a possible implementation, a connection structure 6101 is provided on the connection frame 610 on the base 61, and the connection structure 6101 is used to fix the buckle structure 03 in the device (e.g., the body 01 of the personal protection device). Optionally, a corresponding connection structure may be provided on the body 01 to cooperate with the connection structure 6101 of the connection frame 610, and the connection structure 6101 on the connection frame 610 may be either a protrusion or a groove. Fig.10 The connection structure 6101 is a protrusion, and a groove that is adapted to connect with the protrusion can be set at a corresponding position in the fuselage 01.

[0075] In an optional implementation, the number of the connecting frames 610 is multiple, which can be as follows: Fig.10 , Fig.11 , Fig.12 As shown, there are four connecting frames 610 , and the four connecting frames 610 can be symmetrically or asymmetrically arranged.

[0076] In an optional embodiment, the support frame 62 is further provided with a first through hole 621 and a second through hole 622; the first latch 1 and the second latch 2 are located above the base 61 and respectively pass through the first through hole 621 and the second through hole 622. In the embodiment of the present application, a through hole is provided on the support frame 62, and the latch passes through the through hole to realize the unlocking or locking function.

[0077] It should be noted that, by providing a base 61 and a support frame 62 on the support portion 6, a first through hole 621 and a second through hole 622 provided on the base 61 are provided on the support frame 62, and a first fastener 1 connected to the lever portion 5 of the linkage member and a second fastener 2 connected to the connecting portion 33 of the pushing member 3 are provided above the base 61, and the first fastener 1 and the second fastener 2 can pass through the first through hole 621 and the second through hole 622 respectively, so that when the user applies a force to the force-bearing portion 31 of the pushing member 3, the lever portion 5 and the support portion 6 of the linkage member limit the moving direction of the first fastener 1 and the second fastener 2.

[0078] That is to say, when the user pushes the pusher 3, the first connecting member 51 of the lever portion 5 of the linkage member is subjected to the force and is pushed to move forward of the pusher 3. Through the lever principle, the fulcrum 53 is supported by the third connecting member 620 of the support portion 6, and the second connecting member 52 arranged on the other side of the fulcrum 53 moves with the first clip 1 connected thereto in the opposite direction to the first connecting member 51 (at this time, the rear of the pusher 3), and the second clip 2 is driven by the connecting portion 33 of the pusher 3 to move in the direction away from the first clip 1. If the base 61 for placing the first clip 1 and the second clip 2 is not provided, the specific direction of the first clip 1 moving forward and the specific direction of the second clip 2 moving in the direction away from the first clip 1 have multiple possibilities (or multi-directionality / uncertainty). Therefore, by providing the base 61 of the lever portion 5 and the support portion 6, and arranging the first clip 1 and the second clip 2 above the base 61, the moving directions of the first clip 1 and the second clip 2 are limited.

[0079] Optionally, the first clip 1 and the second clip 2 move in the moving direction, and the moving track formed can be a parallel line parallel to the horizontal plane or an inclined line not parallel to the horizontal plane. In the embodiment of the present application, a side surface (or inner side surface) connected to the base 61 and the support frame 62 can be used as a reference. When the side surface of the base 61 is a surface parallel to the horizontal plane, the moving track of the clip can be a parallel line. In addition, the first clip 1 and the second clip 2 are both arranged above the base 61, and the inner side surfaces of the base 61 corresponding to the positions thereof can be arranged parallel to the horizontal plane or not parallel to the horizontal plane (i.e., inclined), or one can be arranged parallel to the horizontal plane and the other can be arranged inclined to the horizontal plane. As long as it can be realized that when the user applies a force to the pusher 3, the first clip 1 and the second clip 2 move away from each other, and when the force is withdrawn, they move toward each other, so as to achieve the unlocking and locking of the personal protection device.

[0080] Optionally, the first through hole 621 and the second through hole 622 may be arranged opposite to each other or not; the heights of the first through hole 621 and the second through hole 622 relative to the base 61 may be the same or different, as long as they can play the role of unlocking and locking the device. Figure 7 , Figure 8 As shown, a transition portion 320 is provided on the main body 32 , and the transition portion 320 includes a fourth connecting member 321 ; the main body 32 is connected to the force-bearing portion 31 through the transition portion 320 to form a receiving space 322 , and the main body 32 is connected to the first connecting member 51 through the fourth connecting member 321 .

[0081] In the embodiment of the present application, the main body 32 forms a receiving space 322 with the force-bearing part 31 through the transition part 320, which can be specifically designed as a through hole. Its function is mainly to consider that when the lever is working, its end has a small movement, and the receiving space 322 is used to provide space for the small movement of the end to avoid interference with other parts. That is to say, the lever part 5 is arranged between the pusher 3 and the support part 6.

[0082] It should be noted that, by connecting the fulcrum of the lever portion 5 of the linkage member with the third connecting member 620 of the support portion 6, an accommodating space 322 is provided, and a first clip 1 passing through the first through hole 621 and a second clip 2 passing through the second through hole 622 of the support portion 6 are placed above the base 61 of the support portion 6, thereby limiting the movement stroke of the first clip 1 and the second clip 2. In other words, the accommodating space 322 limits the movement stroke of the lever portion 5, that is, the pushing member 3 limits the movement stroke of the first clip 1 and the second clip 2.

[0083] In an optional embodiment, a side surface of the support portion 6 on which the third connecting member 620 is provided is also provided with a guide surface 623 adjacent to the first connecting member 51 of the lever portion 5, and the guide surface 623 may be an inclined surface arranged obliquely. The guide surface 623 guides the lever portion 5 at one end of the first connecting member 51, and when the user pushes the pusher 3, the pusher 3 moves together with the lever portion 5 toward the direction of the support portion 6, and the guide surface 623 also serves to increase the movement stroke of the lever portion 5. At this time, the accommodating space 322 and the guide surface 623 limit the movement stroke of the lever portion 5, and further limit the movement stroke of the first snap member 1 and the second snap member 2, and even limit the movement stroke of the entire snap structure 03, that is, the pusher 3 and the linkage member limit the movement stroke of the lever portion 5, the first snap member 1, and the second snap member 2.

[0084] In an alternative embodiment, see Figure 6 and Figure 8 The first connecting member 51 is a connecting shaft, and an axial hole is set on the fourth connecting member 321, or the first connecting member 51 is an axial hole, and a connecting shaft is set on the fourth connecting member 321; the second connecting member 52 is a connecting shaft, and an axial hole is set on the first fastener 1, or the second connecting member 52 is an axial hole, and a connecting shaft is set on the first fastener 1.

[0085] In the embodiment of the present application, the rotation connection is specifically achieved by the shaft hole matching. In the specific structural design, it can be as follows Figure 6 and Figure 8 As shown, the first connecting member 51 and the second connecting member 52 are designed as connecting shafts, and corresponding matching shaft holes are set on the fourth connecting member 321 and the first snap member 1. Conversely, the first connecting member 51 and the second connecting member 52 can also be designed as shaft holes, and corresponding matching connecting shafts are set on the third connecting member 620 and the first snap member 1.

[0086] Similarly, the connection between the connecting portion 33 and the second clip 2 is a connection between a connecting shaft and an axial hole, that is, the connecting portion 33 includes an axial hole and a connecting shaft, and is connected to the second clip 2 through the connecting shaft and the axial hole. Of course, since the connecting portion 33 and the second clip 2 move synchronously during operation and in the same direction, the connection between the connecting portion 33 and the second clip 2 can also be connected in other fixed connection modes.

[0087] In an optional embodiment, the elastic member 4 is arranged on the inner side of the force-bearing portion 31 adjacent to the first buckle member 1, so as to Fig. 9 In the scenario shown, the elastic member 4 is arranged on the left side of the force-bearing portion 31; and / or the elastic member 4 is arranged on the outer side of the connecting portion 33 facing away from the second buckle 2, so as to Fig. 9 In the scenario shown, the elastic member 4 is arranged on the left side of the connecting portion 33 ( Fig. 9Only the scene where the elastic member 4 is arranged on the force-bearing part 31 is specifically shown in the figure. For the case where the elastic member 4 is arranged on the connecting part 33, it can be understood by reference). In the embodiment of the present application, the setting position of the elastic member 4 can be divided into two categories. One category is to set it relatively inside the buckle structure, that is, the elastic member 4 is arranged on the inner side surface of the force-bearing part 31, which can improve the internal space utilization rate; the other category is to set it relatively outside the buckle structure, that is, the elastic member 4 is arranged on the outer side surface of the connecting part 33, which can avoid affecting the operation of other components in the buckle structure. Of course, the elastic member 4 can also be arranged on both the inner side surface of the force-bearing part 31 and the outer side surface of the connecting part 33 to increase the rebound elastic force.

[0088] In an optional embodiment, when the elastic member 4 is arranged on the inner side surface of the force-bearing portion 31 adjacent to the first snap member 1, the inner side surface is provided with a first fixing member which is arranged on both sides of the lever portion 5 and is used to fix the elastic member 4; in an optional embodiment, when the elastic member 4 is arranged on the outer side surface of the connecting portion 33 facing away from the second snap member 2, the outer side surface is provided with a second fixing member to fix the elastic member 4. In the embodiment of the present application, a fixing member is provided on the corresponding component for different arrangement modes of the elastic member 4. The fixing member may be a fixing column fixedly connected to one end of the elastic member 4, or may be a groove fixedly connected to one end of the elastic member 4. The embodiment of the present application does not limit the type of the fixing member. Figure 3 and Fig. 9 Taking the position where the elastic member 4 is set as an example, when the elastic member 4 is set on the inner side of the force-bearing part 31 adjacent to the first buckle 1, the inner side of the force-bearing part 31 on both sides of the lever part 5 can be set as one or more first fixing members of the groove, and the elastic member 4 is placed on each groove accordingly.

[0089] Optionally, the elastic member 4 can be an elastic component such as a spring, a torsion spring, or a spring sheet that can generate elastic force after a force is applied. The accompanying drawings show a scenario in which the elastic member is a spring, and specifically two springs can be set. It can be understood that according to actual needs, two or more elastic members 4 can also be set. The embodiment of the present application does not limit the number of elastic members 4 to be set.

[0090] The present application embodiment also provides a personal protection device, including a body 01 and a container 02. For details, please refer to Figure 1 , Figure 2 The personal protection device also includes the snap-fit ​​structure 03 as described above; the container 02 is detachably connected to the body 01 via the snap-fit ​​structure 03 .

[0091] In an optional embodiment, if Fig.10 , Fig.11 and Fig.13As shown, the container has a snap-fitting portion 7, and a support frame 62 is sleeved on the snap-fitting portion 7; a first through hole 621 and a second through hole 622 are provided on the support frame 62; when the container is connected to the body through the snap-fitting structure, the first snap-fitting member 1 in the snap-fitting structure passes through the first through hole 621, and the second snap-fitting member 2 in the snap-fitting structure passes through the second through hole 622, and the snap-fitting portion 7 is locked by the first snap-fitting member 1 and the second snap-fitting member 2.

[0092] In the embodiment of the present application, a clamping portion 7 is provided on the container (which may be an outer structure surrounding the container delivery tube, or may be the container delivery tube itself), and the base 61 is designed to be sleeved on the clamping portion 7, which can save internal space of the device. Accordingly, a first through hole 621 and a second through hole 622 are provided on the support frame 62, so that the first clamping member 1 passes through the first through hole 621, and the second clamping member 2 passes through the second through hole 622, so as to lock the clamping portion 7.

[0093] In an optional embodiment, a groove or a through hole matching with the first snap member 1 is provided on the outer side wall of the snap-fitting portion 7 , and a groove or a through hole matching with the second snap member 2 is provided on the outer side wall of the snap-fitting portion 7 .

[0094] In the embodiment of the present application, in order to improve the locking effect of the snap member on the snap-fit ​​portion 7, a groove or a through hole is provided on the outer side wall of the snap-fit ​​portion 7 to cooperate with the snap member to improve assembly reliability. Fig.13 The scene shown in FIG. 7 is that a through hole is provided on the outer side wall of the clamping portion 7 .

[0095] In an optional embodiment, the elastic member 4 in the snap-fit ​​structure is arranged between the force-bearing portion 31 in the snap-fit ​​structure and the support frame 62; and / or, the elastic member 4 in the snap-fit ​​structure is arranged between the connecting portion 33 in the snap-fit ​​structure and the inner side surface of the fuselage 01.

[0096] In the embodiment of the present application, for the case where the elastic member 4 is arranged relatively inside the buckle structure, the elastic member 4 is arranged between the force-bearing portion 31 and the support frame 62. For the case where the elastic member 4 is arranged relatively outside the buckle structure, the elastic member 4 is arranged between the connecting portion 33 and the fuselage 01. Figure 3 , Fig. 9 , Fig.10 , Fig.12 , shows a scenario where the elastic member 4 is disposed between the force-bearing portion 31 and the support frame 62 , which can be understood by reference to the scenario where the elastic member 4 is disposed between the force-bearing portion 31 and the fuselage.

[0097] The buckle structure 03 of the present application is provided with a pushing member 3, a linkage member including a lever portion 5 and a support portion 6, a first buckle member 1, a second buckle member 2, and an elastic member 4. When it is necessary to disassemble or unlock the container 02 of the personal protection device from the body 01 or to insert and install the container 02 in the body 01, the user applies a force to the force-bearing portion 31 of the pushing member 3, and the connecting portion 33 of the pushing member 3 drives the second fastener 2 and the first fastener 1 linked by the lever portion 5 to move away from each other to release the container 02 fixed in the body 01, or the container 02 can be inserted into the main body 32 of the pushing member 3 of the body 01 at this time; if the force on the pushing member 3 is cancelled at this time, the elastic force generated by the elastic member 4 being squeezed due to the force pushes the force-bearing portion 31 or the connecting portion 33, thereby moving the entire pushing member 3 back to the initial position, and driving the second fastener 2 and the first fastener 1 linked by the lever portion 5 to move towards each other, so that the container 02 inserted into the main body 32 of the body 01 is installed or locked with the body 01, which is convenient for unlocking and locking the personal protection device. In addition, no force is applied to the pusher 3 , but the container 02 is directly inserted into the body 01 to achieve locking of the container 02 and the body 01 .
