DETAILED DESCRIPTION

[0032] Exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood, and the scope of the present disclosure can be accurately conveyed to those skilled in the art. It should be noted that the sphygmomanometer described in the present disclosure is only a preferred embodiment of the connector of the present disclosure, and is not a limitation on the application range of the connector. For example, the connector of the present disclosure can also be used in electronic devices such as stethoscopes, and such adjustments do not deviate from the protection scope of the connector of the present disclosure.

[0033] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises", "comprising", "includes", "including" and "has" are inclusive and therefore specify the presence of stated features, elements, components, and / or integers, but do not preclude the presence or addition of one or more other features, elements, components, integers, and / or groups thereof.

[0034] Although the terms first, second, etc. can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can be only used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, the terms such as "first", "second" and other numerical terms when used herein do not imply a sequence or order. In addition, in the description of the present disclosure, unless otherwise explicitly specified and limited, the terms "provide", "connect" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0035] For the sake of description, spatial relative terms can be used herein for the purpose of describing one element or feature's relationship to another element or feature as illustrated in the figures. Such relative terms include, for example, "front", "back", "top", "bottom", "side", "upper", "lower", "above", "below", "inside", "outside", etc. The spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" or "over" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatial relative terms used herein interpreted accordingly.

[0036] In the related art, the connector can only be powered, and for the device that needs to be ventilated, an additional separate air pipe needs to be additionally arranged for ventilation, which will cause the increase of the pipeline on the device. The increase of the pipeline not only increases the occupied space of the connector, but also causes the mutual entanglement phenomenon between the pipelines, which reduces the use experience of the device.

[0037] The disclosure proposes to integrate the conductive part and the gas supply part into a one-piece structure to solve the technical problems of single function and complex structure of the connector in the related art. Compared with the split structure, the number of parts can be reduced, and the interference and entanglement between the parts and the large occupied space can be reduced.

[0039] As shown in FIGS. 1-7, the present disclosure provides a connector 1 for a sphygmomanometer 100, the connector 1 comprising a first connecting assembly 10 and a second connecting assembly 20, the first connecting assembly 10 comprising a first conductive member 12 and a first sleeve 11 sleeved outside the first conductive member 12, a pipe wall of the first sleeve 11 being formed with a hollow first air passage 111; the second connecting assembly 20 comprising a second conductive member 22 and a second sleeve 21 sleeved outside the second conductive member 22, a pipe wall of the second sleeve 21 being formed with a hollow second air passage 201, in the case of abutment of the first connecting assembly 10 and the second connecting assembly 20, the first conductive member 12 and the second conductive member 22 are connected to constitute an electrical connection circuit of the connector 1, and the first air passage 111 and the second air passage 201 are communicated to constitute an air flow connection channel of the connector 1.

[0040] In the present embodiment, the connector 1 proposed by the present disclosure integrates the air flow connection channel and the electrical connection circuit, and sets the electrical connection circuit inside the air flow connection channel, which can protect the electrical connection circuit, and has the technical effects of miniaturization, compact structure, beautiful appearance, fewer components and low cost.

[0041] The connector 1 proposed by the present disclosure can not only be applied to the sphygmomanometer 100, but also be applied to other electronic products requiring air and electricity coexistence, so as to meet the dual needs of air supply and power supply of the sphygmomanometer 100 and other electronic products.

[0042] Taking the application of the connector 1 in the sphygmomanometer 100 as an example, the first conductive member 12 and the second conductive member 22 respectively constitute an audio female seat and an audio male head of the sphygmomanometer 100, both ends of the audio male head and the audio female seat are connected with wires, so as to realize the wire conduction between a host 110 of the sphygmomanometer 100 and a pressure gauge, and the first air passage 111 and the second air passage 201 realize the air conduction between the host 110 of the sphygmomanometer 100 and the pressure gauge.

[0043] When the first connecting assembly 10 and the second connecting assembly 20 are inserted in place, the host 110 of the sphygmomanometer 100 and the pressure gauge are connected with both air and wires, air passes through the air chamber in the host 110 to the air bag of the pressure gauge through the second air passage 201 and the first air passage 111, at this time, the piezoelectric sensor of the pressure gauge generates an electrical signal, which is transmitted to the audio female head in the first connecting assembly 10, then transmitted to the audio male head in the second connecting assembly 20 through the audio female head, and finally transmitted to the host 110 of the sphygmomanometer 100 through the audio male head and the wire, so as to complete the pressure measurement function of the sphygmomanometer 100.

[0044] It should be noted that the specific structure of the conductive part and the sleeve is not limited by the embodiments of the present disclosure, because the application point of the present disclosure is to integrate the conductive part and the sleeve into an integrated structure, and the specific structure of the conductive part and the sleeve includes various embodiments, for example, the conductive part can be provided as a socket, a plug, a connecting piece and a connecting wire, and the sleeve can be provided as a double-layer pipe or a sandwich pipe, which all belong to the protection scope of the conductive part and the sleeve of the present disclosure, and other embodiments of the conductive part and the sleeve will not be described one by one here.

[0045] The specific structure and material of the conductive part and the sleeve of the embodiments of the present disclosure will be described in detail below.

[0047] In the present embodiment, by surrounding the plurality of first air channels 111 with the plurality of partitions 112, on the one hand, the influence of the plurality of first air channels 111 on the structural strength of the first sleeve 11 can be reduced without significantly reducing the wall thickness of the first sleeve 11; on the other hand, the plurality of first air channels 111 can improve the air supply reliability of the sphygmomanometer 100, and reduce the phenomenon of insufficient air supply of the sphygmomanometer 100 caused by blockage of one or two first air channels 111.

[0048] The plurality of partitions 112 can be formed by increasing protrusions on the inner wall of the first sleeve 11, or can be formed by grooving the inner wall of the first sleeve 11, both of which belong to the protection scope of the embodiments of the present disclosure.

[0049] As shown in FIG. 7, in some embodiments, along the inner wall of the first sleeve 11 in the circumferential direction, a part is provided with a plurality of partitions 112, and another part is provided as an arc-shaped convex ring 113, and the height of the arc-shaped convex ring 113 is consistent with the height of the plurality of partitions 112, and the arc-shaped convex ring 113 and the plurality of partitions 112 constitute a radial limiting structure of the first conductive part 12.

[0051] The plurality of partitions 112 can occupy half of the first sleeve 11, or one third or three quarters of the first sleeve 11, according to the actual air supply of the sphygmomanometer 100.

[0055] The conductive part of the first conductive part 12 is arranged on the inner wall of the electrical socket 122 of the first connector 121, and the conductive part of the second conductive part 22 is arranged on the outside of the second conductive part 22. In this way, the conductive connection between the first conductive part 12 and the second conductive part 22 is arranged inside the electrical socket 122, thereby reducing the phenomenon that the gas inside the connector 1 corrodes the conductive parts of the first conductive part 12 and the second conductive part 22.

The second sleeve 21 as an air chamber can buffer the incoming gas to make the fluctuating air pressure more stable. The second sleeve 21 is internally provided with a second conductive member 22, and a gap can be formed between the second conductive member 22 and the inner wall of the second sleeve 21, which can form a first air passage 111. The gas input from the inflation pipe 211 can flow to the pipe opening of the second sleeve 21 through the first air passage 111.

[0074] A part of the second conductive member 22 can pass through the second sleeve 21 away from the pipe opening of the second sleeve 21 and be electrically connected to a sphygmomanometer.

[0078] When the first connecting assembly 10 and the second connecting assembly 20 are connected together, the gas flow path and the electrical connection path are both in conduction, and the gas can enter the second sleeve from the inflation tube 211, then pass through the first airway 111 and the second airway 201 to the connecting tube 13 and finally reach the cuff airbag.

[0079] At this time, the piezoelectric sensor in the cuff airbag generates an electrical signal, which is then transmitted through the wire in the air tube to the DC connector female head and the DC connector male head, and then transmitted through the wire to the host 110 of the sphygmomanometer 100, completing the gas-electric connection of the sphygmomanometer 100 and the blood pressure signal transmission.

[0080] In addition, the embodiments of the present disclosure only focus on the connector 1 and the structure of the sphygmomanometer 100 related to the improvement points of the present disclosure, and do not mean that the connector 1 and the sphygmomanometer 100 do not have other structures. For example, the end of the first sleeve 11 of the connector 1 is also provided with a plug and a nut, and the first sleeve 11 is in communication with the connecting tube 13 of the cuff airbag through the plug and the nut, so as to achieve the purpose of supplying gas and power to the cuff airbag. These structures all belong to the protection scope of the embodiments of the present disclosure, and will not be elaborated one by one here.

[0081] The above is only a preferred specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present disclosure, which should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the present disclosure.
