Description

TECHNICAL FIELD

[0001] The utility model relates to the electrode sucking disc field of medical instrument especially, a kind of electrode sucking disc structure. BACKGROUND

[0002] Electrode sucking disc is important component of interference electric therapeutic instrument, electrode sucking disc is mainly realized to conduct electricity and realizes adsorption fixation in massage site. Generally speaking, electrode sucking disc has conductive site and negative pressure adsorption site, and in the process of generating negative pressure adsorption, water in water-absorbing sponge will be lost due to the reason of negative pressure, causing the deterioration of conductive effect. In addition, too much water will be sucked, and water storage and drainage problems will be caused.

[0003] Patent document JP6529042B2 discloses an electrode sucking disc structure. The skin bowl structure of its electrode sucking disc structure has outer wall and inner wall, i.e. the skin bowl is divided into two circles inside and outside. The chamber between the outer wall and the inner wall is a negative pressure adsorption chamber for realizing negative pressure adsorption. At the same time, electrode sheet and sponge are placed in the chamber inside the inner wall to realize water retention. In this way, even in the process of negative pressure adsorption of negative pressure adsorption chamber, water in the chamber inside the inner wall will not be lost. But such structure in actual use, due to the negative pressure adsorption chamber in the adsorption process, negative pressure will be generated. At this time, the flat outer wall will produce obvious deformation under the action of external atmospheric pressure. The deformation state of the deformed outer wall cannot be controlled, which may cause the edge of the outer wall in contact with the human body to fall off from the surface of the human body, resulting in the defect of the decline of adsorption effect and the failure of adsorption. UTILITY MODEL CONTENT

[0004] The technical problem to be solved by the utility model is to provide an electrode sucking disc structure which can ensure the stability of the shape of the outer wall in the process of negative pressure adsorption, thereby significantly improving the adsorption stability.

[0005] The utility model discloses a technical scheme that solves its technical problems is: electrode sucking disc structure, including skin bowl, the skin bowl includes annular outer wall and annular inner wall, the chamber between the outer wall and inner wall is negative pressure adsorption chamber, the chamber in annular inner wall is conductive chamber, is provided with electrode sheet and sponge in conductive chamber, the sponge is located electrode sheet top, the outer wall is the arc structure that protrudes outwardly.In actual use, the outer wall is the arc structure that protrudes outwardly, when negative pressure adsorption chamber is in the state of negative pressure relative to the outside world, the outer wall will be subjected to the force from the atmospheric pressure of the outside world.Because the outer force that the arc outer wall receives is perpendicular to the surface of the outer wall, and the outer force is uniform, therefore, the whole arc outer wall is in the trend of contraction under the above-mentioned outer force, at this moment, the shape of the outer wall can still be integrally kept as the originally outwardly protruding arc state, and obvious deformation or wrinkle does not occur, finally guarantee the good contact of the outer wall and human body.Therefore, such arc structure design prevents the defect that the planar outer wall in the original structure is subjected to the force of the atmospheric pressure of the outside world and produces great deformation or wrinkle.The skin bowl in the scheme can keep good adsorption effect during the whole negative pressure use, greatly improving the adsorption stability of the electrode sucking disc.

[0006] Further, the skin bowl includes a filter screen mounting hole that communicates the negative pressure adsorption chamber with the outside world, and a filter screen is detachably arranged in the filter screen mounting hole.During the process of ensuring that the negative pressure adsorption chamber is always in a state of negative pressure, air in the negative pressure adsorption chamber needs to be extracted out.The filter screen can filter the human body dander or other impurities carried in the air extraction process, prevent the dander or impurities from blocking the pipeline, and even damage the machine equipment.The detachable filter screen can be subsequently disassembled, replaced and cleaned.

[0007] Further, the skin bowl includes an inner wall rib strip arranged in the conductive chamber, the outer peripheral edge of the inner wall rib strip is tightly attached to the inner wall of the conductive chamber to support the inner wall, and the electrode sheet is arranged between the inner wall rib strip and the sponge.During the process of the negative pressure adsorption chamber being in a state of negative pressure, the conductive chamber will deform under the action of atmospheric pressure, which may cause the electrode sheet to be pressed and separated from the sponge, affecting the conductive area.After the inner wall rib strip is added, the deformation of the conductive chamber can be prevented, and the electrode sheet is pressed on the sponge, effectively ensuring the conductive effect during use.As for the specific structure of the inner wall rib strip, the two support rib strips are oppositely arranged, the support rib strips are connected by a connecting rib strip to form an integral structure, and the shape of the support rib strip matches the curved shape of the inner wall.The support rib strip and the connecting rib strip form a ring-shaped support structure, ensuring the stability of the shape of the conductive chamber and the conductive effect.

[0008] In order to further improve the sealing effect of the outer wall in actual use, the edge of the outer wall in contact with the human body can be provided with an outer wall bending part, and the bending direction of the outer wall bending part is towards the negative pressure suction cavity. The outer wall bending part can adapt to the slight deformation of the outer wall during the negative pressure application process, so that the deformed outer wall can also form good contact with the human body contact surface, thereby improving the sealing effect. Based on the same design principle, the edge of the inner wall in contact with the human body can be provided with an inner wall bending part, and the bending direction of the inner wall bending part is towards the conductive cavity, so that the deformed inner wall can also form good contact with the human body contact surface, thereby improving the sealing effect.

[0009] In order to take into account the adsorption effect of negative pressure and the limiting of sponge by inner wall, the following scheme can be selected: the wall thickness of the inner wall is greater than the wall thickness of the outer wall. This scheme can make the deformation amount of the inner wall smaller during the negative pressure adsorption process, and the deformation amount of the outer wall is greater than that of the inner wall, thereby ensuring that the outer wall deforms to achieve adsorption during adsorption, and the inner wall remains limited to the sponge, thereby ensuring the fitting effect.

[0010] As a preferred structure of the electrode sheet, the electrode sheet can include an electrode sheet body and an electrode sheet connecting pipe connecting the electrode sheet body with the outside, the electrode sheet connecting pipe is arranged in the electrode sheet through hole of the cup, and the electrode sheet through hole and the electrode sheet connecting pipe are sealed. The electrode sheet connecting pipe passes through the electrode sheet through hole and is connected with the electrode sheet body, and the electrode sheet through hole and the electrode sheet connecting pipe are sealed to ensure that the negative pressure suction cavity is not gas leakage. Further, the electrode sheet body and the electrode sheet connecting pipe can be fixedly connected through four-point welding bending pieces, thereby realizing fixed connection between the plate-shaped electrode sheet body and the tubular electrode sheet connecting pipe.

[0011] At the same time, the electrode sheet connecting pipe can be provided with a connecting pipe exhaust hole for sucking out the gas in the negative pressure suction cavity. Since the air in the negative pressure suction cavity needs to be sucked out in actual use, the connecting pipe exhaust hole can be integrated on the electrode sheet connecting pipe, and the connecting pipe exhaust hole is arranged near the filter screen mounting hole, thereby sucking out the air in the negative pressure suction cavity, ensuring the negative pressure effect of the negative pressure suction cavity, and thereby ensuring that the cup is stably adsorbed on the human body surface.

[0012] The beneficial effects of the utility model are: through the ingenious design of the outer wall shape as the outward convex arc, under the condition of little change to the existing structure, the problem of the original structure in the negative pressure adsorption process caused by the deformation of the outer wall leading to the decline of the adsorption effect is solved. The outward convex arc of the outer wall bears the pressure of the external atmospheric pressure in the negative pressure adsorption process, and the arc of the outer wall makes the outer wall not easy to deform under external force, thereby greatly improving the adsorption stability. The utility model is especially suitable for electrode suction disc. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0017] The utility model is further illustrated below in combination with the drawings and embodiments.

[0018] As Figure 1 , Figure 2 , Figure 3 indicated is an embodiment of the electrode chuck structure. Figure 1 In the embodiment, the electrode chuck structure comprises a leather bowl 1, an electrode sheet 2, a filter screen 3 and a sponge 4 arranged on the leather bowl 1 for filtering. The leather bowl 1 is preferably made of silica gel material, has a certain deformation capacity, and also has a stable supporting effect. The electrode sheet 2 comprises an electrode sheet body uniformly provided with a plurality of mesh holes, and an electrode sheet connecting pipe 21 connected with the electrode sheet body, and in order to stabilize and reliably connect the above, the electrode sheet body and the electrode sheet connecting pipe 21 are fixedly connected through a four-point welding bending piece 22. The electrode sheet 2 and the sponge 4 are arranged in a conductive cavity 13, wherein the sponge 4 is located on the outside and directly contacts the skin, that is, the sponge 4 is located between the skin and the electrode sheet 2. When conducting electricity, the sponge 4 contacts the skin to conduct the current of the electrode sheet 2 to the skin. The negative pressure adsorption cavity 12 and the conductive cavity 13 separate the leather bowl 1 into an outer ring and an inner ring, prevent the moisture of the sponge 4 from being adsorbed by the negative pressure adsorption cavity 12, so that the conductive performance of the sponge 4 in the conductive cavity 13 and the negative pressure adsorption performance of the negative pressure adsorption cavity 12 are both taken into account. In actual use, the sponge 4 needs to be preheated and moistened with warm water or soaked with warm water, and then the current is conducted on the sponge 4 with water through the electrode sheet 2 to give electrotherapy.

[0019] Figure 3The structure of the skin cup 1 is shown. In the specific structure of the skin cup 1, two different functional areas are formed by the separation of the outer wall 6 and the inner wall 7, i.e. the chamber between the outer wall 6 and the inner wall 7 is the negative pressure adsorption chamber 12; the chamber inside the annular inner wall 7 is the conductive chamber 13. Among them, the electrode sheet 2 and the sponge 4 are arranged in the conductive chamber 13, and the sponge 4 and the electrode sheet 2 are arranged closely, the sponge 4 is closely arranged with the human body surface, and the corresponding electrotherapy function is realized. The negative pressure adsorption chamber 12 realizes the adsorption effect of the whole electrode suction cup by maintaining the state of negative pressure under the action of atmospheric pressure. Among them, the outer wall 6 is an outwardly convex arc structure, that is, similar to the convex arc structure of the side of the drum. Compared with the traditional flat outer wall, it has stronger structural stability in actual use. Specifically, when the negative pressure adsorption chamber 12 maintains the state of negative pressure, the external atmospheric pressure will exert pressure on the outwardly convex arc outer wall 6, and the pressure is uniformly distributed on the outer wall 6 along the direction perpendicular to the surface of the outer wall 6. Under the action of this external force, the outer wall 6 has a tendency to shrink inward. Since the outer wall 6 is outwardly convex, when facing the tendency to shrink inward, the material inside the outer wall 6 will also generate a corresponding counterforce, and the external atmospheric pressure will reach a balance. This balance only requires a small deformation of the outer wall 6, thereby preventing the outer wall 6 from deforming greatly. Since the outer wall 6 deforms very little, it can ensure that the edge of the outer wall 6 in contact with the human body can always be well fitted on the surface of the human body, and thus the electrode suction cup can maintain stable adsorption effect. In actual design, a connecting pipe exhaust hole for exhausting gas in the negative pressure adsorption chamber 12 can be provided on the electrode sheet connecting pipe 21. By sequentially connecting the negative pressure adsorption chamber 12, the filter screen mounting hole 15 and the connecting pipe exhaust hole, the gas in the negative pressure adsorption chamber 12 is exhausted, realizing the stable adsorption of the electrode suction cup.

[0020] In actual use, since the negative pressure adsorption chamber 12 generates from negative pressure to stable, it will cause the outer wall 6 and the inner wall 7 to produce a slight deformation. In order to ensure that the edge of the outer wall 6 and the inner wall 7 in contact with the human body always fits well during the above slight deformation process, it is preferred that the edge of the outer wall 6 in contact with the human body is provided with an outer wall bending part 61, and the bending direction of the outer wall bending part 61 is towards the negative pressure adsorption chamber 12, and it is preferred that the edge of the inner wall 7 in contact with the human body is provided with an inner wall bending part 71, and the bending direction of the inner wall bending part 71 is towards the conductive chamber 13. Through the outer wall bending part 61 and the inner wall bending part 71, the fitting effect can be ensured, and the sealing performance of the negative pressure adsorption chamber 12 can be ensured. In addition, in the Figure 3 , the skin cup 1 is also provided with a filter screen mounting hole 15, which connects the annular negative pressure adsorption chamber 12 between the outer wall 6 and the inner wall 7 with the outside, and a filter screen 3 is detachably arranged in the filter screen mounting hole 15, thereby filtering the dandruff or other impurities of the human body during the gas extraction process.

[0021] Figure 2 As shown, it is the structure diagram of the inner wall rib 14 and its installation. The inner wall rib 14 includes two support ribs 141 arranged oppositely, and the support ribs 141 are connected by connecting ribs 142 to form an integrated structure. The shape of the support rib 141 matches the curved shape of the inner wall 7. The support rib 141 and the connecting rib 142 jointly form a ring-shaped support structure, which is arranged in the conductive cavity 13. The outer peripheral edge of the support rib 141 is tightly attached to the inner wall of the conductive cavity 13 to support the inner wall 7. The electrode sheet 2 is arranged between the inner wall rib 14 and the sponge 4. Through the support of the inner wall rib 14, firstly, the electrode sheet 2 can be tightly attached to the sponge 4 during the entire use process, thereby ensuring the electrotherapy effect. Secondly, the inner wall rib 14 can support the inner wall 7 during the negative pressure adsorption process, preventing the inner wall 7 from being squeezed inwardly and damaging the electrode sheet 2 due to atmospheric pressure, or preventing the inner wall 7 from being squeezed inwardly to separate the electrode sheet 2 from the sponge 4 due to atmospheric pressure.
