Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology and relates to an air intake connector. Background Technology

[0002] In automobiles, gas sampling connectors are required as accessories. Traditional gas sampling connectors typically employ a single, fixed flow channel structure. To achieve full-flow, cut-off, or diversion of gas, additional auxiliary control components such as check valves and relief valves are often needed. This not only increases equipment costs and installation space but may also increase system complexity due to the combination of multiple components, raising the risk of leaks and maintenance difficulties. Furthermore, traditional connectors rely heavily on manually adjusting valves or simple mechanical structures for flow control, making it difficult to achieve high-precision flow control and failing to meet the demands of modern industry for precise gas flow regulation. In addition, traditional gas sampling connectors have relatively limited functionality, unable to achieve flexible gas diversion and sampling without interrupting the main gas path, thus limiting their application scenarios. Therefore, there is an urgent need to design a gas sampling connector that is compact, functionally integrated, and possesses high-precision flow control capabilities. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing an air intake connector.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An air intake connector includes a connector body, which has an air inlet, an air outlet, and an air intake port. The air inlet and air outlet are horizontally coaxial, and the air intake port is vertically upward. The air inlet, air outlet, and air intake port converge within the connector body to form an inverted T-shaped flow channel. A rotatable valve core is provided within the inverted T-shaped flow channel. The valve core is provided with a controllable flow-through switching structure. Connecting parts are installed at the outlets of the air inlet, air outlet, and air intake port.

[0006] In the aforementioned gas intake connector, the controllable flow connection switching structure includes a transverse inlet / outlet flow channel and an inlet connection part disposed within the valve core body. The transverse inlet / outlet flow channel is provided with a flow control adjustment component, and the transverse inlet / outlet flow channel and the inlet connection part are arranged alternately.

[0007] In the above-mentioned gas intake connector, the flow control adjustment component includes two flow-blocking blocks disposed in the valve core body. The flow-blocking blocks are made of magnetically conductive material and can extend into the transverse inlet and outlet flow channels. The valve core body is provided with an electromagnetic drive component for driving the flow-blocking blocks to move up and down.

[0008] In the aforementioned gas intake connector, the electromagnetic drive component includes an electromagnet disposed within the valve core body, and the position of the electromagnet corresponds to that of the flow-blocking block.

[0009] In the aforementioned gas intake connector, a spring is fitted on the flow-stopping block. When the flow-stopping block extends into the transverse inlet / outlet channel, the spring is in a compressed state. When the flow-stopping block contacts the electromagnet, the spring is in a reset state.

[0010] In the above-mentioned air intake connector, the intake connection includes an inlet connection channel and an outlet connection channel disposed in the valve core body. The inlet connection channel and the outlet connection channel form an L-shaped flow channel, and the inlet connection channel and the outlet connection channel are respectively staggered with the transverse inlet and outlet flow channels.

[0011] In the aforementioned air intake connector, an adjusting shaft valve is provided at the bottom of the valve core body.

[0012] In the above-mentioned air intake connector, the top of the valve core is provided with an anti-deviation ring, which is embedded in the inner wall of the connector body and rotates with the inner wall of the connector body.

[0013] In the above-mentioned air intake connector, the connector includes a metal connecting pipe port disposed at the outlet of the air inlet, air outlet and air intake port, and a fastening sleeve is provided between the metal connecting pipe port and the connector body.

[0014] In the aforementioned air intake connector, several sealing rings are provided between the fastening sleeve and the metal connecting pipe opening.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] 1. During use, this utility model, through its uniquely designed controllable flow switching structure, can achieve three modes of "full flow / cut-off / proportional diversion" with just one air intake connector, without the need for additional one-way valves or overflow valves, effectively simplifying the system structure and reducing equipment costs and installation space requirements.

[0017] 2. This utility model utilizes the combination of a flow-blocking block and an electromagnetic drive component to precisely control the flow rate of the channel formed by the air inlet and outlet according to actual needs. Compared with traditional manual or simple mechanical control methods, the control accuracy is significantly improved, which can meet the needs of high-precision gas transmission and sampling.

[0018] 3. The valve core in this invention features a rotatable design, which, combined with the internal switching structure, allows for rapid switching of the gas flow path without interrupting the main gas path. This meets the gas transmission and intake requirements under different operating conditions, greatly improving the flexibility and convenience of use.

[0019] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1-3 As shown, an air intake connector includes a connector body 1. The connector body 1 has an air inlet 2, an air outlet 3, and an air intake 4. The air inlet 2 and the air outlet 3 are horizontally coaxial, and the air intake 4 is vertically upward. The air inlet 2, the air outlet 3, and the air intake 4 converge in the connector body 1 to form an inverted T-shaped flow channel. A rotatable valve core 5 is provided in the inverted T-shaped flow channel. The valve core 5 is provided with a controllable flow-connection switching structure 6. Connecting parts 7 are installed at the outlets of the air inlet 2, the air outlet 3, and the air intake 4.

[0026] In this embodiment, the inverted T-shaped flow channel design provides a basic path framework for gas flow. The rotatable valve core 5, together with the controllable flow-type connection switching structure 6, provides a hardware foundation for realizing multiple gas flow modes. The connector 7 facilitates connection with external gas pipelines, ensuring the universality and practicality of the connector. This structure integrates multiple functions into one, simplifies the overall architecture of the gas transmission system, and reduces installation and maintenance costs and improves system stability compared to the traditional multi-component combination method.

[0027] Combination Figure 1-3 As shown, the controllable flow-connection switching structure 6 includes a transverse inlet / outlet channel 8 and an inlet connecting part 9 disposed in the valve core body 5. The transverse inlet / outlet channel 8 is provided with a flow control adjustment element 10, and the transverse inlet / outlet channel 8 and the inlet connecting part 9 are arranged alternately.

[0028] Specifically, the transverse inlet and outlet channels 8 are mainly used to realize the gas flow between the inlet 2 and the outlet 3, while the inlet connecting part 9 is used to realize the gas flow between the inlet 2 and the outlet 4. The two are arranged alternately, so that by rotating the valve core 5, the flow can be switched between two different flow paths. The setting of the flow control adjustment component 10 further provides the possibility of flow control, realizing the function switching of "full passage / cut-off / proportional diversion". Compared with the traditional fixed flow channel connector, the function is richer and more flexible.

[0029] The flow control adjustment component 10 includes two flow-blocking blocks 11 disposed within the valve core body 5. The flow-blocking blocks 11 are made of magnetically conductive material and can extend into the transverse inlet / outlet flow channel 8. The valve core body 5 is provided with an electromagnetic drive component 12 for driving the flow-blocking blocks 11 to move up and down. The electromagnetic drive component 12 includes an electromagnet 13 disposed within the valve core body 5. The electromagnet 13 corresponds to the position of the flow-blocking blocks 11. A spring 14 is sleeved on the flow-blocking blocks 11. When the flow-blocking blocks 11 extend into the transverse inlet / outlet flow channel 8, the spring 14 is in a compressed state. When the flow-blocking blocks 11 contact the electromagnet 13, the spring 14 is in a reset state.

[0030] In this embodiment, when the electromagnet 13 is energized, it generates magnetism, attracting the magnetically guided flow-blocking block 11 to move upward, compressing the spring 14. At this time, the flow-blocking block 11 partially or completely exits the transverse inlet / outlet channel 8, allowing gas to pass freely and achieving a full-flow mode. When the electromagnet 13 is de-energized, its magnetism disappears, and the spring 14 resets, pushing the flow-blocking block 11 downward to extend into the transverse inlet / outlet channel 8. Depending on the extent of extension, the gas is proportionally diverted or completely cut off. By controlling the on / off state and current magnitude of the electromagnet 13, the position of the flow-blocking block 11 can be precisely controlled, thereby achieving high-precision regulation of gas flow. Compared with traditional mechanical regulation methods, this electromagnetically driven flow control method has a fast response speed and high precision, meeting the requirements for precise control of gas flow under complex working conditions.

[0031] Combination Figure 3 As shown, the inlet connecting part 9 includes an inlet connecting channel 15 and an outlet connecting channel 16 disposed in the valve core body 5. The inlet connecting channel 15 and the outlet connecting channel 16 form an L-shaped flow channel. The inlet connecting channel 15 and the outlet connecting channel 16 are respectively staggered with the transverse inlet and outlet flow channels 8.

[0032] In this embodiment, when the valve core 5 is rotated so that the inlet connection channel 15 is aligned with the air inlet 2 and the outlet connection channel 16 is aligned with the air outlet 4, gas can flow from the air inlet 2 through the inlet connection channel 15 and the outlet connection channel 16 to the air outlet 4, thus achieving the gas intake function. The L-shaped flow channel design ensures a reasonable flow direction of gas within the valve core 5, and the staggered arrangement with the transverse inlet and outlet flow channels 8 ensures that the two flow paths do not interfere with each other. The valve core 5 can be rotated to quickly switch between them, meeting different gas transmission requirements and improving the flexibility of the connector.

[0033] The valve core 5 is provided with an adjusting shaft valve 17 at the bottom and an anti-deviation ring 18 at the top. The anti-deviation ring 18 is embedded in the inner wall of the connector body 1 and rotates with the inner wall of the connector body 1.

[0034] In this embodiment, the adjustable rotary valve 17 facilitates manual or mechanical drive of the valve core 5 to rotate, thereby enabling the switching of the gas flow path. The anti-deviation ring 18 is embedded in the inner wall of the connector body 1, playing a guiding and positioning role during the rotation of the valve core 5, preventing the valve core 5 from shifting or shaking, ensuring the stability and reliability of the rotation of the valve core 5, and thus ensuring the accuracy and stability of the gas flow path switching, reducing the risk of gas leakage and control errors caused by valve core shaking.

[0035] Combination Figure 1-3 As shown, the connector 7 includes a metal connecting pipe 19 disposed at the outlets of the air inlet 2, the air outlet 3 and the air intake 4. A fastening sleeve 20 is provided between the metal connecting pipe 19 and the connector body 1, and a plurality of sealing rings 21 are provided between the fastening sleeve 20 and the metal connecting pipe 19.

[0036] In this embodiment, the metal connecting port 19 provides a connection interface for the external gas pipeline, and the fastening sleeve 20 is used to firmly fix the metal connecting port 19 to the connector body 1 to ensure the stability of the connection; the setting of the sealing ring 21 effectively enhances the sealing of the connection, prevents gas leakage, and ensures the reliability and safety of the entire gas take-up connector during the gas transmission process. The connector has a reasonable structural design, is easy to install, and can adapt to the connection requirements of gas pipelines of different specifications.

[0037] The working principle of this utility model is as follows:

[0038] Full-flow mode: When gas needs to flow directly from the inlet 2 to the outlet 3, rotate the adjusting shaft valve 17 to align the transverse inlet / outlet channel 8 in the valve core 5 with the inlet 2 and outlet 3. At this time, the electromagnet 13 is energized, attracting the flow-blocking block 11 to move upward. The spring 14 is compressed, and the flow-blocking block 11 completely exits the transverse inlet / outlet channel 8. Gas can flow unimpeded from the inlet 2 through the transverse inlet / outlet channel 8 to the outlet 3, thus achieving the full-flow mode.

[0039] Cut-off mode: When it is necessary to cut off the gas flow between the inlet 2 and the outlet 3, the electromagnet 13 is de-energized, the magnetism disappears, the spring 14 resets and pushes the flow blocking block 11 downward to fully extend into the transverse inlet and outlet channel 8, blocking the transverse inlet and outlet channel 8, thereby cutting off the gas flow and realizing the cut-off mode.

[0040] Proportional flow splitting mode: When it is necessary to proportionally split the gas between the inlet 2 and the outlet 3, the current of the electromagnet 13 is controlled to adjust the magnetic force of the electromagnet 13, thereby controlling the extent to which the flow-blocking block 11 extends into the transverse inlet and outlet flow channel 8. The length of the flow-blocking block 11 extending into the flow channel varies, and the degree of obstruction to the gas also varies, thereby achieving proportional adjustment of the gas flow rate and achieving the purpose of proportional flow splitting.

[0041] Gas intake mode: When it is necessary to take gas from the air inlet 2, rotate the adjusting shaft valve 17 to align the inlet connection channel 15 in the valve core 5 with the air inlet 2 and the outlet connection channel 16 with the gas intake port 4. At this time, the gas can flow from the air inlet 2 through the inlet connection channel 15 and the outlet connection channel 16 to the gas intake port 4 to realize the gas intake function. During the gas intake process, the gas intake flow rate can also be precisely adjusted by controlling the position of the throttling block 11.

[0042] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.

[0043] Although this document frequently uses terms such as connector body 1, air inlet 2, air outlet 3, air intake 4, valve core 5, controllable flow switching structure 6, connector 7, transverse inlet / outlet channel 8, inlet / outlet connecting part 9, flow control adjustment component 10, flow cut-off block 11, electromagnetic drive component 12, electromagnet 13, spring 14, inlet connection channel 15, outlet connection channel 16, adjusting shaft valve 17, anti-deviation ring 18, metal connection pipe port 19, fastening sleeve 20, and sealing ring 21, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
