[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A passive micro-negative pressure application auxiliary pen, comprising an outer shell, a rebound component, a pressing component, and an excitation component.

[0009] The outer shell is a split structure of upper and lower shells, which are an upper shell and a lower shell respectively. An upper accommodating cavity is formed in the middle of the upper shell, and a lower accommodating cavity is formed in the middle of the lower shell. A rebound component and an excitation component connected to each other are arranged in the direction of the central axis where the upper accommodating cavity and the lower accommodating cavity are located.

[0010] The rebound component includes a rebound rod and a stamping component on the outer periphery of the rebound rod, and a first connecting cavity penetrating from top to bottom is formed in the middle of the rebound rod, and the rebound rod is stimulated downward in the lower accommodating cavity by the stamping component;

[0011] A second connecting cavity is formed in the middle of the pressing assembly, and the pressing assembly and the rebound rod are coaxially fixedly connected in the lower accommodating cavity to achieve gas communication between the first connecting cavity and the second connecting cavity.

[0012] The excitation component is located at the side of the upper shell, forming a movement limit for the pressing component in the vertical direction;

[0013] The lower end surface of the rebound rod forms an adsorption for the patch, and by driving the excitation component, the rebound component is excited and pressed down, so that the patch on the rebound rod is released from adsorption and attached to a designated position.

[0014] Furthermore, the outer shell is divided into two upper and lower independent cylindrical structures connected to each other;

[0015] The stamping assembly is a downward pressure spring, and a boss protruding toward the central axis of the lower housing is formed on the upper part of the lower housing, and the lower housing cavity formed in the middle is used for the outer diameter of the rebound rod to penetrate and be movably connected;

[0016] At the same time, a boss extending toward the outer periphery is synchronously formed at the bottom of the rebound rod, so that the upper and lower bosses are respectively connected and fixed to the upper and lower ends of the stamping assembly.

[0017] Furthermore, the inner diameter of the lower accommodating cavity is larger than the inner diameter of the upper inner wall of the lower shell body, so as to form a clearance space when the boss at the lower part of the rebound rod moves in the direction of the central axis.

[0018] Furthermore, a clamping groove is provided on the lower end surface where the rebound rod is located, and the clamping groove is connected with the lower end of the first connecting cavity, and the clamping of the outer wall of the application is achieved through the clamping groove.

[0019] Furthermore, first openings are symmetrically arranged on both sides of the upper part of the upper shell, and a second opening concentric with the first opening is transversely penetrated through the upper part of the pressure assembly, so that the excitation assembly penetrates the first opening and the second opening at the same time.

[0020] Furthermore, the second opening forms a clearance cavity in the up-down direction, so that when the pressing component moves in the up-down direction, a clearance space is formed for the exciting component in the up-down direction.

[0021] Furthermore, a connecting cavity is formed at the joint of the rebound rod and the pressing assembly, and the first connecting cavity is connected with the second connecting cavity through the connecting cavity;

[0023] Furthermore, a pressing cavity opened upward is formed at the upper portion of the pressing assembly, and a plurality of groups of the second openings are connected to the pressing cavity.

[0024] Furthermore, the excitation assembly includes a first excitation block and a second excitation block, and a reset spring member is used to connect the first excitation block and the second excitation block. When the reset spring member is in a tensioned state, it opens toward the outside of the first opening to form a downward movable limit for the downward pressing assembly.

[0025] Furthermore, a limiting member is coaxially arranged on the upper outer wall of the pressing assembly along the interior of the upper accommodating cavity of the upper shell, and a support foot is formed at the bottom of the limiting member;

[0026] At the same time, a downwardly penetrating slot is provided in the vertical direction where the first excitation block and the second excitation block are located, and the bottom support leg of the limiter is located on the projection surface where the slot is located;

[0027] When the first excitation block and the second excitation block form an extrusion on the middle return spring member, the slot is moved to the projection surface of the bottom support leg of the limiting member, and driven by the stamping assembly, the limiting member and the slot are released from the limit.

[0047] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] like Figure 1 As shown, an embodiment of the present invention provides a passive micro-negative pressure application auxiliary pen, including an upper shell 1, a rebound component 2, a downward pressure component 3, an excitation component 4, and a lower shell 5.

[0049] like Figure 3 , Figure 4 As shown, the outer shell is a straight-through structure that runs through the upper and lower parts, and is generally divided into an upper shell 1 and a lower shell 5. They are processed separately in an independent processing manner and then assembled, which improves the assembly efficiency. Of course, according to the process requirements, the outer shell 1 can also be set as an integrated molding structure. The overall appearance is an integrated structure, which is beautiful and easy to carry.

[0050] like Figure 2 As shown, an upper accommodating cavity 101 and a lower accommodating cavity 102 are formed in the vertical direction in the middle of the outer shell 1, and the upper accommodating cavity 101 and the lower accommodating cavity 102 are respectively located in the middle of the upper shell 1 and the lower shell 5, and in the central axis direction of the upper accommodating cavity 101 (that is, the central axis direction of the lower accommodating cavity 102 is coaxial with the central axis direction of the upper accommodating cavity 101), there are provided with a rebound component 2 and an excitation component 3 (at this time, the rebound component 2 is located below the excitation component 3 and is coaxially arranged and fixed).

[0051] like Figure 5-9 As shown, the rebound component 2 includes a rebound rod 21 and a stamping component 22 on the periphery of the rebound rod 21. A first connecting cavity 201 penetrating from top to bottom is formed in the middle portion where the rebound rod 21 is located. The stamping component 22 enables the rebound rod 21 to perform a downward stamping movement in the lower accommodating cavity 102 (the stamping component 22 in the present application is a downward pressure spring. Of course, according to the actual scene requirements, it can also be other stamping components, which can mainly form the excitation energy storage for the rebound rod 21, all of which are within the protection scope of the present application).

[0052] When the stamping assembly 22 is a downward pressure spring, at this time, a boss protruding toward the central axis direction of the downward accommodating cavity 102 is formed on the upper part of the lower shell body 5, and the lower accommodating cavity 102 formed in the middle is used for the outer diameter of the rebound rod 21 to penetrate and move, and at the same time, a boss extending toward the periphery is synchronously formed at the bottom of the rebound rod 21. The upper and lower boss structures form a limit for the upper and lower ends of the downward pressure spring, so as to realize the upper and lower bosses are respectively connected and fixed to the upper and lower ends where the stamping assembly 22 is located.

[0053] At this time, the outer diameter of the lower part of the rebound rod 21 is larger than the inner diameter of the upper inner wall, so as to form a clearance space when the boss at the lower part of the rebound rod 21 moves in the direction of the central axis.

[0054] A card slot 211 is provided on the lower end face where the rebound rod 21 is located, and the card slot 211 is connected to the lower end of the first connecting cavity 201, and the card slot 211 is used to engage with the outer wall of the patch, that is, customized operation is performed according to the actual shape and size requirements of the outer periphery of the patch, and the depth of the card slot 211 at this time is consistent with the actual thickness of the patch, so that when the rebound rod 21 is pressed down, when the card slot 211 is completely fitted on the outer periphery of the patch, the downward pressure will not continue to cause pressure loss to the patch; in addition, the material of the card slot 211 is elastic silicone, and the lower surface and the upper surface of the patch are also completely fitted, so that the effect of micro-negative pressure will be better.

[0055] like Figure 8 As shown, a second connecting cavity 301 is formed in the middle part where the down-pressing component 3 is located, and the down-pressing component 3 and the rebound rod 21 are coaxially fixedly connected in the upper accommodating cavity 101 and the lower accommodating cavity 102 to realize the gas connection between the first connecting cavity 201 and the second connecting cavity 301; of course, according to actual needs, a connecting cavity is formed at the junction of the rebound rod 21 and the down-pressing component 3, and the connection between the first connecting cavity 201 and the second connecting cavity 301 is realized through the connecting cavity; the second connecting cavity 301 is provided with two channels bypassing the second opening 302 where the down-pressing component 3 is located, and is connected to the upper part of the down-pressing component 3. In order to better control the air tightness of the upper part of the pressing component 3, a pressing chamber 303 with an upper opening is formed at the upper part of the pressing component 3, and two second connecting chambers 301 are connected to the pressing chamber 303. When the upper part of the pressing chamber 303 is closed (that is, the upper part of the pressing chamber 303 is covered and closed by gently pressing the finger), the first connecting chamber 201 and the second connecting chamber 301 can be simultaneously airtightly closed.

[0056] During actual use, the upper part of the pressing cavity 303 is closed, and a channel is formed only at the lower part of the first connecting cavity 201. At this time, the card slot 211 located below the first connecting cavity 201 forms a cover for the patch, and then a slight negative pressure is formed in the entire connecting cavity, which causes adsorption of the patch and then transports it to the designated position to be bonded.

[0057] like Fig.11 As shown, the excitation component 4 is located at the side of the upper shell 1, forming a movement limit for the downward pressure component 3 in the vertical direction; the excitation component 4 includes a first excitation block 41 and a second excitation block 42 combined together, and a reset spring member 43 is installed between the first excitation block 41 and the second excitation block 42 (the reset spring member 43 can realize the connection and interaction between the first excitation block 41 and the second excitation block 42 to form an outward tension).

[0058] Mutually symmetrical first openings 103 are laterally arranged on both sides of the upper part of the upper shell 1, and a second opening 302 coaxial with the first opening 103 is laterally penetrated at the upper part of the pressing component 3, so that the excitation component 4 simultaneously transversely penetrates the first opening 103 and the second opening 302, and when the reset spring member 43 is in a tensioned state, it opens to the outside of the first opening 103 to form a downward limit for the pressing component 3.

[0059] The second opening 302 forms a clearance cavity in the up-down direction, so that when the pressing component 3 moves in the up-down direction, a clearance space is formed for the exciting component 4 in the up-down direction.

[0060] A limiting member 31 is coaxially arranged on the upper outer wall of the pressing assembly 3 along the interior of the upper accommodating cavity 101 of the upper shell 1, and a support leg 311 is formed at the bottom of the limiting member 31 (such as Fig.13 shown).

[0061] At the same time, a downwardly penetrating slot 401 is provided in the vertical direction where the first excitation block 41 and the second excitation block 42 are located, and the bottom leg of the limiter 31 is located on the projection surface where the slot 401 is located (such as Fig.14 shown).

[0062] When the first excitation block 41 and the second excitation block 42 form an extrusion on the middle return spring member 43, the slot 401 is moved to the projection surface of the bottom support foot of the limiting member 31 (in order to ensure the concentricity of the second opening 302 which is concentric with the first opening 103, a limiting platform is arranged above the upper shell 1, so as to relatively fix the moving position of the limiting member 31), and driven by the stamping assembly 22, the limiting member 31 and the slot 401 are mutually engaged and limited.

[0063] like Fig.10 The state shown in the figure is before excitation, that is, during specific use, the excitation component 4 is first expanded outward under the action of the return spring member 43 in the middle, thereby forming a limit on the downward movement direction of the bottom support leg 311 of the limiting member 31 (that is, when the limiting member 31 descends, it cannot be aligned with the slot 401 on the excitation component 4). This limiting method also simultaneously forms a downward limit on the pressing component 3. At this time, the upper part of the pressing component 3 is covered by fingers, so that the first connecting cavity 201 and the second connecting cavity 301 are formed as a non-connected cavity as a whole (only the lower part is connected to the air, and the upper part is a closed structure). When the bottom of the first connecting cavity 201 contacts the application patch, a local micro-negative pressure adsorption effect can be formed.

[0064] At the same time, the bottom of the rebound rod 21 is recessed at the bottom of the lower housing 5 .

[0065] like Fig.12As shown, after being transferred to the designated position and tightly attached, the reset spring member 43 is squeezed and deformed toward the middle by pressing the excitation component 4, so that the slots 401 on the first excitation block 41 and the second excitation block 42 are moved to below the bottom support 311 of the limit member 31. At the same time, under the action of the stamping spring, the downward resistance of the rebound rod 21 is eliminated, that is, it will synchronously drive the connected pressing component 3 to move downward, so that the bottom of the rebound rod 21 protrudes from the lowest part where the lower shell 5 is located. At this time, after the application is fitted in the slot 211, the finger placed on the upper part of the pressing cavity 303 is released, so that the first connecting cavity 201 is connected to the upper and lower ends of the second connecting cavity 301, and when fitted, it is more firm (and when fitted, because the limit member 31 forms a limit on the excitation component 4 and under the action of the spring tension of the stamping component 22, the excitation component 4 will not rebound at this time, preventing the phenomenon of accidental touch and re-excitation).

[0066] After the bonding is completed, if you need to continue the application, gently press the 303 cavity with your thumb, aim at the next application, and press the rebound rod 21 downward to realize the upward rebound of the downward pressure component 3 connected to its upper part, thereby synchronously driving the rebound of the limiter 31. At this time, the excitation component 4 lacks lateral limitation, because the internal stamping spring is compressed, which will generate an outward expansion force, causing the excitation component to move outward and reset to the excitation state. The entire device is ready for the next excitation and can be reused.

[0067] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
