[0031] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that the connector of the present application described in this application through a sphygmomanometer is only a preferred embodiment and does not limit the scope of application of the connector. For example, the connector of the present application can also be used in electronic devices such as stethoscopes, and this adjustment does not deviate from the protection scope of the connector of the present application.

[0032] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an", and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", and "have" are inclusive and therefore specify the presence of stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0033] Although the terms first, second, etc. may be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. In addition, in the description of this application, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0034] For ease of description, spatial relative terms can be used in the text to describe the relationship of an element or feature relative to another element or feature as shown in the figure, and these relative terms are, for example, "end", "length", "inside", "outside", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation except the orientation depicted in the figure. For example, if the mechanism in the figure flips, the element described as "below other elements or features" or "below other elements or features" will be subsequently oriented to "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include the orientation on and below. The mechanism can be oriented in addition (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0035] Existing connectors can generally only be powered by electricity. For equipment that requires ventilation, a separate air pipe needs to be installed for ventilation. This will lead to an increase in pipelines on the equipment. The increase in pipelines will not only increase the space occupied by the connector, but also cause the pipelines to become entangled with each other, reducing the user experience of the equipment.

[0036] In order to solve the technical problem that existing connectors cannot have both a single function and a complex structure, the present application proposes integrating the conductive parts and the air supply parts into an integrated structure. Compared with a split structure, this can reduce the number of components, and reduce the interference and entanglement between the components and the large space occupied.

[0037] like Figures 1 to 7 As shown, an embodiment of the present application provides a connector 1 for a sphygmomanometer 100, wherein the connector 1 includes a first connecting component 10 and a second connecting component 20, wherein the first connecting component 10 includes a first conductive member 12 and a first sleeve 11 sleeved outside the first conductive member 12, wherein a hollow first air channel 111 is formed on the tube wall of the first sleeve 11; wherein the second connecting component 20 includes a second conductive member 22 and a second sleeve 21 sleeved outside the second conductive member 22, wherein a hollow second air channel 201 is formed on the tube wall of the second sleeve 21, and when the first connecting component 10 is docked with the second connecting component 20, the first conductive member 12 is connected to the second conductive member 22 to form an electrical connection circuit of the connector 1, and the first air channel 111 is connected to the second air channel 201 to form an airflow connection channel of the connector 1.

[0038] In this embodiment, the connector 1 proposed in the present application integrates the airflow connection channel and the electrical connection circuit into one, and arranges the electrical connection circuit inside the airflow connection channel, which can protect the electrical connection circuit and has the technical effects of miniaturization, compact structure, beautiful appearance, few parts and low cost.

[0039] The connector 1 proposed in the present application can be applied not only to the sphygmomanometer 100, but also to other electronic products that require the coexistence of gas and electricity, so as to meet the dual needs of electronic products such as the sphygmomanometer 100 for gas supply and power supply.

[0040] Taking the application of connector 1 to sphygmomanometer 100 as an example, the first conductive member 12 and the second conductive member 22 respectively constitute the audio female socket and the audio male connector of the sphygmomanometer 100. Both ends of the audio male connector and the audio female socket are connected to wires, thereby realizing the wire conduction between the host 110 of the sphygmomanometer 100 and the pressure gauge. The first airway 111 and the second airway 201 are connected to realize the ventilation conduction between the host 110 of the sphygmomanometer 100 and the pressure gauge.

[0041] Specifically, when the first connecting component 10 and the second connecting component 20 are plugged into place, the gas and the wires are connected between the main unit 110 of the sphygmomanometer 100 and the pressure meter, and the gas reaches the air bag of the pressure meter through the gas chamber in the main unit 110 through the second air channel 201 and the first air channel 111. At this time, the piezoelectric sensor of the pressure meter generates an electrical signal, which is transmitted to the audio female connector through the wires in the first connecting component 10, and then transmitted to the audio male connector and wires of the second connecting component 20 through the audio female connector, and finally transmitted to the main unit 110 of the sphygmomanometer 100, thereby completing the pressure measurement function of the sphygmomanometer 100.

[0042] It should be noted that the embodiments of the present application do not limit the specific structure of the conductive part and the sleeve, because the invention point of the present application is to integrate the conductive part and the sleeve into an integrated structure. As for the specific structure of the conductive part and the sleeve, it includes a variety of embodiments. For example, the conductive part can be set as a socket, a plug, a connecting piece and a connecting wire, and the sleeve can be set as a double-layer tube or a sandwich tube. These embodiments all belong to the protection scope of the conductive part and the sleeve of the present application. As for other embodiments of the conductive part and the sleeve, they will not be elaborated one by one here.

[0043] The specific structure and material of the conductive member and the sleeve according to the embodiment of the present application are described in detail below.

[0044] like Figure 7 As shown, in some embodiments, the inner wall of the first sleeve 11 is provided with a plurality of partitions 112 distributed along the circumferential direction, a plurality of open grooves are formed between the plurality of partitions 112 , and the plurality of open grooves and the outer wall of the first conductive member 12 are surrounded to form a plurality of first air channels 111 .

[0045] In this embodiment, by enclosing a plurality of first air passages 111 with a plurality of partitions 112, on the one hand, it is possible to avoid significantly reducing the wall thickness of the first sleeve 11 and reduce the influence of the first air passage 111 on the structural strength of the first sleeve 11; on the other hand, the plurality of first air passages 111 can improve the air supply reliability of the sphygmomanometer 100 and reduce the phenomenon of insufficient air supply to the sphygmomanometer 100 caused by blockage of one or two first air passages 111.

[0046] Specifically, the plurality of partitions 112 may be formed by adding protrusions to the inner wall of the first sleeve 11 , or by digging grooves on the inner wall of the first sleeve 11 , and both methods fall within the protection scope of the embodiments of the present application.

[0047] like Figure 7 As shown, in some embodiments, along the circumference of the inner wall of the first sleeve 11, a portion is provided with multiple partitions 112, and another portion is provided with an arc-shaped convex ring 113, and the height of the arc-shaped convex ring 113 is consistent with the height of the multiple partitions 112, and the arc-shaped convex ring 113 and the multiple partitions 112 constitute a radial limiting structure of the first conductive member 12.

[0048] In this embodiment, through the cooperation of multiple partitions 112 and the arc-shaped convex ring 113, the structural strength of the first sleeve 11 can be improved, and the influence of the first air duct 111 on the wall thickness of the first sleeve 11 can be reduced, so that the first sleeve 11 can have sufficient structural strength to meet the working requirements of bending and folding.

[0049] Specifically, multiple partitions 112 can occupy half of the circle of the first sleeve 11, or can occupy one-third or three-quarters of the first sleeve 11, depending on the actual air supply of the sphygmomanometer 100. When the actual air supply of the sphygmomanometer 100 is large, multiple partitions 112 can occupy three-quarters of the first sleeve 11; when the actual air supply of the sphygmomanometer 100 is small, multiple partitions 112 can occupy one-third of the first sleeve 11.

[0050] Further, taking the application of the connector 1 to the sphygmomanometer 100 as an example, the audio mother socket of the sphygmomanometer 100 is installed in the interior of the first sleeve 11 and bonded with glue. Part of the outer wall of the audio mother socket is bonded to the arc-shaped convex ring 113 in the first sleeve 11, and another part of the outer wall of the first sleeve 11 forms a first air channel 111. The first air channel 111 is formed through the gap between adjacent partitions 112, and the partitions 112 are used to support the audio mother socket to remain in the center position.

[0051] like Figures 4 to 7As shown, in some embodiments, the first conductive member 12 includes a first connector 121 and an electrical slot 122 disposed inside the first connector 121 . The first connector 121 is configured to cooperate with the first sleeve 11 , and the electrical slot 122 is configured to cooperate with the second conductive member 22 .

[0052] In this embodiment, the first conductive member 12 and the second conductive member 22 are configured to be plug-in compatible, which can not only achieve the purpose of connection reliability between the first conductive member 12 and the second conductive member 22, but also improve the plug-in sealing between the first conductive member 12 and the second conductive member 22, and reduce the phenomenon of gas inside the connector 1 corroding the conductive parts of the first conductive member 12 and the second conductive member 22.

[0053] Specifically, the conductive portion of the first conductive member 12 is distributed on the inner wall of the electrical slot 122 of the first connector 121, and the conductive portion of the second conductive member 22 is distributed on the outside of the second conductive member 22. With this arrangement, the conductive connection portion between the first conductive member 12 and the second conductive member 22 can be distributed inside the electrical slot 122, thereby reducing the phenomenon that the gas inside the connector 1 corrodes the conductive portions of the first conductive member 12 and the second conductive member 22.

[0054] like Figures 4 to 7 As shown, in some embodiments, a limiting tube 212 cooperating with the second conductive member 22 is disposed inside the second sleeve 21, the tube diameter of the second sleeve 21 is larger than the outer diameter of the limiting tube 212, and a second air passage 201 is formed between the inner wall of the second sleeve 21 and the outer wall of the limiting tube 212.

[0055] In this embodiment, the inner wall of the limiting tube 212 can limit and fix the second conductive component 22, thereby reducing the shaking and falling-off phenomenon of the second conductive component 22 inside the second sleeve 21; a second airway 201 is formed between the outer wall of the limiting tube 212 and the inner wall of the second sleeve 21, so that the airflow of the sphygmomanometer 100 can flow in the second airway 201.

[0056] like Figures 4 to 7 As shown, in some embodiments, the second sleeve 21 is provided with an inflation tube 211 connected to the second airway 201, one end of the inflation tube 211 is configured to be connected to the air chamber, and the other end of the inflation tube 211 passes through the inner wall of the second sleeve 21 and is connected to the second airway 201, and the second airway 201 and the inflation tube 211 are distributed in a T shape.

[0057] In this embodiment, taking the connector 1 applied to the sphygmomanometer 100 as an example, an air chamber and an air pump are provided in the main unit 110 of the sphygmomanometer 100. During the operation of the sphygmomanometer 100, a joint of the air chamber is connected to the air pump, and the air chamber serves as the air chamber of the sphygmomanometer 100. The two ends of the air pump are respectively connected to the air chamber and the inflation tube 211 of the second airway 201, so as to provide the gas in the air chamber to the second airway 201 of the connector 1 through the inflation tube 211; at the same time, the air chamber also has the function of buffering the pulsating gas, making the fluctuating air pressure more stable.

[0058] Specifically, a sealing ring is installed at the interface of the air warehouse, the outer side of the sealing ring contacts the interface of the air warehouse, the inner circle of the sealing ring contacts the outer circle of the inflation tube 211, and the gap between the inflation tube 211 and the interface of the air warehouse is smaller than the diameter of the sealing ring, so that the sealing ring can be compressed to achieve the effect of sealing the gas.

[0059] like Figures 4 to 7 As shown, in some embodiments, the second sleeve 21 is sleeved onto the first sleeve 11 , and a flange 213 is formed at the butt end of the second sleeve 21 , and a sealing ring 23 is provided between the flange 213 and the first sleeve 11 .

[0060] In this embodiment, a sealing ring 23 is provided between the flange 213 and the first sleeve 11 , so that the sealing ring 23 can seal the gap between the second sleeve 21 and the first sleeve 11 , thereby reducing air leakage between the second sleeve 21 and the first sleeve 11 .

[0061] In addition, the sealing ring 23 can also limit the second sleeve 21 and the first sleeve 11 to reduce the relative slippage or falling off between the second sleeve 21 and the first sleeve 11.

[0062] like Figure 4 and Figure 7 As shown, in some embodiments, the limiting tube 212 and the second sleeve 21 form an integrated structure, and a retaining ring 214 is connected between the limiting tube 212 and the second sleeve 21 .

[0063] In this embodiment, the limiting tube 212 and the second sleeve 21 are configured as an integrated structure, thereby improving the reliability of the position stability between the limiting tube 212 and the second sleeve 21 and reducing the possibility of the limiting tube 212 and the second conductive member 22 falling off and shaking in the second sleeve 21.

[0064] Specifically, the retaining ring 214 is arranged at the pipe mouth of the second sleeve 21, and has the function of connecting the limiting tube 212 and the second sleeve 21 into an integrated structure, and the function of sealing the second air channel 201 at the pipe mouth of the second sleeve 21 to prevent the gas in the second air channel 201 from leaking out at the pipe mouth of the second sleeve 21.

[0065] like Figures 1 to 7 As shown, the second aspect of the present application provides a sphygmomanometer 100, which includes a host 110, a connector 1 and a pressure meter. The host 110 is connected to the pressure meter via the connector 1, and the connector 1 is configured as the connector 1 of the first aspect of the present application. The sphygmomanometer 100 supplies power and ventilation to the pressure meter via the connector 1.

[0066] In this embodiment, the pressure meter includes a cuff air bag that can contact the human body. When the main unit 110 of the sphygmomanometer 100 is connected to the pressure meter through the connector 1, the gas and wires of the sphygmomanometer 100 are connected, and the gas of the sphygmomanometer 100 reaches the cuff air bag through the gas chamber and the connecting tube 13 of the cuff air bag. At this time, the piezoelectric sensor in the cuff air bag generates an electrical signal, which is then transmitted to the audio female connector and the audio male connector through the wires in the trachea, and then transmitted to the main unit 110 of the sphygmomanometer 100 through the wires, completing the gas-electric connection of the sphygmomanometer 100 and the transmission of blood pressure signals.

[0067] like Figures 1 to 7 As shown, in some embodiments, the first connection component 10 of the connector 1 constitutes an audio female connector of the sphygmomanometer 100 , and the second connection component 20 of the connector 1 constitutes an audio male connector of the sphygmomanometer 100 .

[0068] In this embodiment, the outer ring of the audio male connector is a metal ring, and the inside of the audio female connector is a contact spring. When the audio male connector is inserted into the audio female connector, the contact spring contacts the metal ring to achieve conduction between the audio male connector and the audio female connector. Both ends of the audio male connector and the audio female connector are connected to wires, thereby achieving conduction of the wires of the blood pressure monitor 100.

[0069] In addition, the embodiments of the present application only focus on the structures in the connector 1 and the sphygmomanometer 100 that are related to the improvements of the present application, and do not mean that the connector 1 and the sphygmomanometer 100 do not have other structures. For example, a plug and a nut are also provided at the end of the first sleeve 11 of the connector 1. The first sleeve 11 is connected to the connecting tube 13 of the cuff airbag through the plug and the nut, so as to achieve the purpose of supplying air and electricity to the cuff airbag. These structures all belong to the protection scope of the embodiments of the present application and will not be elaborated one by one here.

[0070] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the present application.
