[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present application.

[0048] As shown in Figure 1 , the present embodiment provides a passive micro-negative pressure patch auxiliary pen, which comprises an upper shell 1, a rebound assembly 2, a pressing assembly 3, an excitation assembly 4, and a lower shell 5.

[0049] As shown in Figure 3 , Figure 4 , the outer shell is a straight-through structure penetrating from top to bottom, which is generally divided into an upper shell 1 and a lower shell 5 and is processed separately in a separate processing manner, and then assembled, thereby improving the assembly efficiency. Of course, according to the process needs, the outer shell 1 can also be provided as an integrally formed structure, and the overall appearance is an integrated structure, which is beautiful and convenient to carry.

[0050] As shown in Figure 2 , an upper accommodating cavity 101 and a lower accommodating cavity 102 are formed in the vertical direction of the middle part of the outer shell 1, and the upper accommodating cavity 101 and the lower accommodating cavity 102 are located in the middle part of the upper shell 1 and the lower shell 5, respectively, and the rebound assembly 2 and the excitation assembly 4 are provided in the central axis direction of the upper accommodating cavity 101 (i.e. the central axis direction of the lower accommodating cavity 102 is coaxial with the central axis direction of the upper accommodating cavity 101) and are connected to each other (at this time, the rebound assembly 2 is located below the excitation assembly 4 and is coaxially arranged and fixed).

[0051] As shown in Figures 5-9 , the rebound assembly 2 comprises a rebound rod 21 and a stamping assembly 22 outside the rebound rod 21, and a first communication cavity 201 penetrating from top to bottom is formed in the middle part of the rebound rod 21, and the stamping assembly 22 realizes the downward stamping movement of the rebound rod 21 in the lower accommodating cavity 102 (in this application, the stamping assembly 22 is a downward spring, and of course, according to the actual scene needs, it can also be other stamping parts, which mainly can form excitation and energy storage for the rebound rod 21, and all are within the protection scope of this application).

[0052] When the stamping assembly 22 is a downward spring, at this time, a boss protruding in the central axis direction of the downward accommodating cavity 102 is formed in the upper part of the lower shell 5, and the lower accommodating cavity 102 formed in the middle part is used for the rebound rod 21 to penetrate and move in the outer diameter, and a boss extending outward is synchronously formed in the bottom of the rebound rod 21, and the upper and lower boss structures limit the upper and lower ends of the downward spring, so as to realize the connection and fixation of the upper and lower bosses with the upper and lower ends of the stamping assembly 22.

[0053] At this time, the outer diameter of the lower part of the rebounding rod 21 is greater than the inner diameter of the upper part, so as to form a space for the movement of the boss of the lower part of the rebounding rod 21 in the direction of the central axis.

[0054] A clamping groove 211 is arranged on the lower end surface of the rebounding rod 21, and the clamping groove 211 is communicated with the lower end of the first communication cavity 201. The clamping groove 211 is used to clamp the outer wall of the patch. According to the actual shape and size of the outer wall of the patch, the clamping groove 211 can be customized. At this time, the depth of the clamping groove 211 is consistent with the actual thickness of the patch. When the clamping groove 211 is completely attached to the outer wall of the patch, the patch will not be damaged by the pressure of the rebounding rod 21. In addition, the clamping groove 211 is made of elastic silica gel, and the lower surface of the clamping groove 211 is completely attached to the upper surface of the patch. Therefore, the effect of micro-negative pressure is better.

[0055] As shown in Figure 8 , the middle part of the lower pressing assembly 3 is formed with a second communication cavity 301 which penetrates up and down. The lower pressing assembly 3 is coaxially fixedly connected with the rebounding rod 21 in the upper accommodating cavity 101 and the lower accommodating cavity 102, so as to realize the gas communication between the first communication cavity 201 and the second communication cavity 301. According to actual needs, a connecting cavity is arranged at the joint of the rebounding rod 21 and the lower pressing assembly 3, so as to realize the communication between the first communication cavity 201 and the second communication cavity 301. The second communication cavity 301 is provided with two passages which bypass the second opening 302 of the lower pressing assembly 3 and are communicated with the upper part of the lower pressing assembly 3. In order to better control the air tightness of the upper part of the lower pressing assembly 3, an upper open pressing cavity 303 is arranged at the upper part of the lower pressing assembly 3, and the two second communication cavities 301 are communicated with the pressing cavity 303. When the upper part of the pressing cavity 303 is closed (i.e. the upper part of the pressing cavity 303 is covered and closed by a finger), the air tightness of the mutual communication between the first communication cavity 201 and the second communication cavity 301 is closed.

[0056] In actual use, the upper part of the pressing cavity 303 is closed, and only the lower part of the first communication cavity 201 is provided with a passage. At this time, the clamping groove 211 below the first communication cavity 201 is clamped on the patch, and the whole communication cavity forms a micro-negative pressure, which generates an adsorption on the patch. Then, the patch is transported to the designated position to be attached.

[0057] As shown in Figure 11 , the excitation assembly 4 is arranged at the side of the upper shell 1, and is used to limit the movement of the lower pressing assembly 3 in the vertical direction. The excitation assembly 4 comprises a first excitation block 41 and a second excitation block 42 which are combined together, and a reset spring 43 is arranged between the first excitation block 41 and the second excitation block 42 (the reset spring 43 can realize the connection and interaction between the first excitation block 41 and the second excitation block 42, and forms an outward tension).

[0058] First openings 103 are symmetrically arranged on both sides of the upper part of the upper shell 1, and second openings 302 are arranged through the upper part of the lower pressing assembly 3 concentrically with the first openings 103, so that the exciting assembly 4 is arranged through the first openings 103 and the second openings 302 at the same time, and the reset spring member 43 is arranged to be stretched to the outside of the first openings 103 to form a downward pressing limit for the lower pressing assembly 3.

[0059] The second openings 302 are arranged to form a space for the lower pressing assembly 3 to move in the up-down direction.

[0060] The limit member 31 is arranged coaxially inside the upper accommodating cavity 101 of the upper shell 1 on the upper part of the lower pressing assembly 3, and the bottom of the limit member 31 is arranged to form a supporting leg 311 (as shown in Figure 13 ).

[0061] The downward slot 401 is arranged in the vertical direction of the first exciting block 41 and the second exciting block 42, and the bottom supporting leg of the limit member 31 is arranged in the projection plane of the downward slot 401 (as shown in Figure 14 ).

[0062] When the first exciting block 41 and the second exciting block 42 are arranged to press the middle reset spring member 43, the downward slot 401 is arranged to move to the projection plane of the bottom supporting leg of the limit member 31 (in order to ensure the concentricity of the second openings 302 concentric with the first openings 103, a limit table is arranged above the upper shell 1, so that the moving position of the limit member 31 is relatively fixed), and the limit member 31 is arranged to be clamped and limited with the downward slot 401 under the driving of the stamping assembly 22.

[0063] As shown in Figure 10 , it is the state before excitation, that is, in specific use, the reset spring member 43 in the middle of the exciting assembly 4 is arranged to expand outwardly under the action, so as to form a downward movement direction limit for the bottom supporting leg 311 of the limit member 31 (that is, when the limit member 31 is lowered, it cannot be aligned with the downward slot 401 on the exciting assembly 4), and this limit mode also synchronously forms a downward limit for the lower pressing assembly 3, and at this time, the upper part of the lower pressing assembly 3 is covered by the fingers, so as to form a non-communicating cavity for the first communicating cavity 201 and the second communicating cavity 301 as a whole (only the lower part is communicated with air, and the upper part is a closed structure), and when the bottom of the first communicating 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 member 21 is recessed below the lowermost position of the lower shell 5.

[0065] As shown in Figure 12As shown, when transported to the designated position and close to the back, at this time by pressing the excitation assembly 4, the reset spring member 43 is synchronously extruded and deformed to the middle, so that the slot 401 on the first excitation block 41 and the second excitation block 42 is moved to below the bottom foot 311 of the limiting member 31, at the same time, the resistance of the downstroke of the rebound rod member 21 is eliminated under the action of the stamping spring, that is, it will synchronously drive the connected down pressure assembly 3 to move downward, so that the bottom of the rebound rod member 21 protrudes the lowermost part of the lower shell 5, and at this time, the finger placed in the pressing cavity 303 is loosened, the upper end of the first communication cavity 201 and the second communication cavity 301 is communicated, and the finger is placed in the pressing cavity 303. When adhering, it is more firm (and when adhering, due to the limiting of the limiting member 31 to the excitation assembly 4 and the spring tension of the stamping assembly 22, at this time, the rebound of the excitation assembly 4 will not be caused, preventing the phenomenon of accidental touch and re-excitation).

[0066] After the adhesion is completed, if it is necessary to continue to adhere, the thumb is lightly pressed on the 303 cavity, aligned with the next patch, and the rebound rod member 21 is pressed downward, so that the upspring of the down pressure assembly 3 connected to the upper part of the rebound rod member 21 is realized, thereby synchronously driving the rebound of the limiting member 31, at this time, the excitation assembly 4 lacks limiting in the transverse direction, because the internal stamping spring is compressed, that is, the outward expansion force is generated, so that the excitation assembly moves outward, resets to the excitation state, and the whole device is ready for the next excitation, which can realize repeated use.

[0067] The above shows and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
