Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a water-air connection structure. Background Technology

[0002] Many modern devices, such as carpet cleaners, multi-functional cleaning equipment, or specific industrial tools, require the simultaneous supply of liquids, recovery of gas or gas-liquid mixtures, and transmission of electrical control signals at the work terminal. The cleaning equipment needs to deliver clean water or cleaning agents to the nozzles, while using negative pressure airflow to pump the wastewater back into the wastewater tank inside the equipment. The motors or valves at the nozzles require electrical energy to drive them.

[0003] In existing technologies, a separate connection scheme is typically used to achieve the aforementioned multiple functions. This means that operators need to connect the water supply pipe, the recycling pipe, and the independent electrical control connectors separately. This separate connection method makes the operation process cumbersome and complicated, requiring multiple independent plugging and unplugging actions each time the equipment is used or stored, significantly reducing work efficiency. More importantly, multiple independent pipelines are prone to tangling and twisting during operation, which not only hinders operational flexibility but also increases the risk of loosening of connections due to pipeline pulling. In addition, due to the dispersed connection points, operators are prone to missing or incorrect connections in a hurry, resulting in the equipment failing to start properly or malfunctioning. Especially in application environments where water and electricity coexist, the dispersed electrical connectors also increase the safety hazard of accidental electric shock, posing a threat to the safety of operators. Existing technologies lack an integrated solution that can integrate water, gas, and electrical circuits and complete all connections in a single operation.

[0004] Therefore, this utility model proposes a water-air connection structure to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of existing water-gas connection structures, which require multiple separate connections of water, gas and electrical circuits, resulting in cumbersome and inefficient operation, and are prone to equipment failure and safety hazards due to incorrect or missing connections, this utility model aims to provide a water-gas connection structure with improved structure that can achieve rapid and safe connection of water, gas and electricity.

[0006] This utility model provides a water-air connection structure, including: a water pump end connector, the water pump end connector is provided with a first exhaust pipe, a second water supply pipe, a contact plate and a nozzle water outlet pipe, the nozzle water outlet pipe is provided with a first water supply pipe, a second exhaust pipe, a pin and a sealing ring.

[0007] The nozzle outlet pipe has a plug portion that is adapted to the mating chamber inside the water pump end connector.

[0008] Furthermore, the water pump end connector, the nozzle outlet pipe, and the sealing ring are combined in a pluggable manner. When connected, the first water supply pipe and the second water supply pipe are interconnected, the second exhaust pipe and the first exhaust pipe are interconnected, the pin contacts the contact plate to form an electrical circuit, and the sealing ring is compressed at the connection interface to achieve fluid sealing.

[0009] Preferably, the sealing ring is radially compressed between the outer wall of the first water supply pipe and the inner wall of the second water supply pipe, and between the outer wall of the second exhaust pipe and the inner wall of the first exhaust pipe during docking. This circumferential compression sealing method is more reliable than simple end face sealing and can effectively prevent leakage caused by lateral vibration or pressure fluctuation.

[0010] Preferably, the outer diameter of the first water supply pipe is smaller than the inner diameter of the second water supply pipe, and the outer diameter of the second vent pipe is smaller than the inner diameter of the first vent pipe. This design, where the male end pipe is slightly smaller than the female end pipe, forms a natural guide bevel in the initial stage of docking, making the insertion action smoother and reducing the difficulty of alignment.

[0011] Preferably, the pin protrudes from the end face of its insertion part along the insertion and removal direction of the nozzle water outlet pipe, and the contact plate is an elastic conductive sheet. The cooperation between the rigid pin and the elastic contact plate ensures that even if there is slight wear after long-term use, a stable electrical contact pressure can be maintained through elastic compensation.

[0012] Preferably, the axes of the first vent pipe and the second water supply pipe in the water pump end connector are parallel to each other, and the axes of the first water supply pipe and the second vent pipe in the nozzle outlet pipe are also parallel to each other. This parallel pipe layout makes the entire connector structure compact and neat, which helps to reduce the overall size of the connector.

[0013] Preferably, the contact plate is positioned deeper than the end faces of the first exhaust pipe and the second water supply pipe. This structural depth difference cleverly creates a safe timing sequence of sealing first and then energizing, ensuring that actuators such as water pumps are always started only after the pipeline is sealed, thus avoiding the risk of no-load operation or pressurized leakage.

[0014] Preferably, the channel formed by the first exhaust pipe and the second exhaust pipe is used to recycle sewage, and the channel formed by the first water supply pipe and the second water supply pipe is used to transport clean water, so that the two functions of cleaning and recycling can be carried out in parallel in the same connector, achieving a high degree of functional integration.

[0015] Preferably, the pin, the first water supply pipe and the second exhaust pipe are integrally formed on the nozzle water outlet pipe, and the contact plate, the first exhaust pipe and the second water supply pipe are also integrally formed on the water pump end connector. The integral forming process not only greatly reduces the number of parts and assembly steps, but also improves the overall strength and durability of the product by reducing the assembly gap.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem that in the prior art, water supply pipes, exhaust pipes and electrical contact structures need to be connected separately, which is cumbersome, time-consuming and inefficient. By integrating water supply pipes, exhaust pipes and electrical contact structures into male and female connectors, this invention solves the problem that water, gas and electrical circuits need to be connected separately, which is cumbersome, time-consuming and inefficient.

[0017] 2. This utility model solves the problem in the prior art that the misconnection of pipes or lines due to human negligence can easily lead to equipment damage or failure to work properly by designing a unique male-female docking form and ensuring that the positions of the internal water supply, exhaust and electrical control components correspond one-to-one.

[0018] 3. This utility model, by designing the structural position of the electrical contact point to be deeper than the sealing position of the fluid pipeline, ensures that the electrical contact structure can only be connected after the pipeline forms an effective seal. This solves the problem in the prior art where the equipment starts prematurely before the fluid channel is sealed due to the circuit being connected too early, thus causing safety hazards such as water leakage and air leakage.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 4This utility model provides a water-air connection structure, which aims to solve the problem in the prior art that the connection between fluid and electrical control signal requires multiple independent connections, which is cumbersome and prone to incorrect connection, leading to leakage or electrical failure.

[0023] like Figure 1 and Figure 2 As shown, the water-air connection structure includes a water pump end connector 1 as the female end and a nozzle outlet pipe 3 as the male end, which is pluggably connected to the water pump end connector 1.

[0024] Specifically, refer to Figure 3 and Figure 4 The water pump end connector 1 has a docking chamber inside. The first exhaust pipe 4 and the second water supply pipe 7 are fixed at the bottom of the docking chamber in parallel at intervals. The contact plate 8 is also fixed on the bottom surface of the docking chamber for receiving electrical signals. The nozzle outlet pipe 3 has a plug-in part whose shape is adapted to the docking chamber. At the end of the plug-in part, the first water supply pipe 5 and the second exhaust pipe 6 are fixed at intervals in parallel. The pin 2 is also fixed at the end of the plug-in part for transmitting electrical signals.

[0025] To achieve precise alignment, the position and diameter of the first water supply pipe 5 correspond to those of the second water supply pipe 7, and the position and diameter of the second exhaust pipe 6 correspond to those of the first exhaust pipe 4. Furthermore, the position of the pin 2 corresponds to that of the contact plate 8. A sealing ring 9 is also provided at the end of the nozzle outlet pipe 3, surrounding the openings of the first water supply pipe 5 and the second exhaust pipe 6. When the nozzle outlet pipe 3 is inserted into the docking chamber of the pump end connector 1 and connected in place, the first water supply pipe 5 and the second water supply pipe 7 are aligned end-to-end to form a complete water supply channel, and the second exhaust pipe 6 and the first exhaust pipe 4 are aligned end-to-end to form a complete exhaust channel. The pin 2 and the contact plate 8 abut against each other to form an electrical control circuit. Simultaneously, the sealing ring 9 is compressed at the docking interface, thereby achieving a reliable fluid seal at the connection between the water supply channel and the exhaust channel.

[0026] Please refer to Figure 3 and Figure 4As a key component for achieving fluid sealing, the sealing ring 9 is fixed around the outer circumference of the inlet of the water supply pipe 5 and the outer circumference of the inlet of the second exhaust pipe 6. During the docking process between the nozzle outlet pipe 3 and the water pump end connector 1, the sealing ring 9 is radially compressed between the outer wall of the water supply pipe 5 and the inner wall of the second water supply pipe 7, and between the outer wall of the second exhaust pipe 6 and the inner wall of the first exhaust pipe 4, as the insertion part penetrates deeper. This design utilizes the elastic deformation of the sealing ring 9 to form a double circumferential seal at the pipe connection, thereby effectively preventing liquid or gas leakage during water supply and exhaust processes. To ensure a smooth and accurate insertion and docking process, the outer diameter of the water supply pipe 5 is designed to be smaller than the inner diameter of the second water supply pipe 7. Similarly, the outer diameter of the second exhaust pipe 6 is also designed to be smaller than the inner diameter of the first exhaust pipe 4. This difference in size forms a guiding insertion fit, allowing the male end of the pipe to easily find and enter the female end in the initial docking stage, avoiding alignment difficulties or component damage caused by collision.

[0027] In the implementation structure of the electrical control path, the pin 2 protrudes from the end face of the plug along the insertion axis of the nozzle outlet pipe 3, while the contact plate 8 can be designed as an elastic conductive sheet and fixedly installed at the bottom of the docking chamber of the water pump end connector 1. When the docking is completed, the rigid pin 2 will press the elastic contact plate 8 to ensure that a stable electrical contact with a certain contact pressure is formed between the two, thereby ensuring the reliability of the control signal transmission.

[0028] As a preferred embodiment, in order to ensure the orderliness and structural stability of the pipeline connection, the central axes of the first vent pipe 4 and the second water supply pipe 7 in the pump end connector 1 are set to be parallel to each other. Similarly, the central axes of the water supply pipe 5 and the second vent pipe 6 in the nozzle outlet pipe 3 are also parallel to each other. This parallel layout allows the two connectors to match precisely like building blocks when they are connected, which simplifies the alignment process and enhances the overall structural strength after connection.

[0029] As another preferred embodiment, in order to further improve operational safety, the timing of electrical contact between the pin 2 and the contact plate 8 is designed to be later than the sealing timing of the pipeline.

[0030] Specifically, by designing the contact plate 8 to be positioned deeper than the end faces of the first exhaust pipe 4 and the second water supply pipe 7, it can be ensured that the tip of the protruding pin 2 will only contact the contact plate 8 and connect the circuit after the nozzle outlet pipe 3 is fully inserted and the sealing ring 9 has effectively sealed the pipeline. This mechanism of sealing first and then energizing can effectively eliminate the risk of liquid leakage caused by the water pump starting prematurely when the pipeline is not completely sealed.

[0031] As another preferred embodiment, in order to achieve a clearer functional distinction and application scenario, the channel formed by the first exhaust pipe 4 and the second exhaust pipe 6 connected thereto can be used exclusively for recycling sewage or exhaust gas generated during use, while the channel formed by the first water supply pipe 5 and the second water supply pipe 7 connected thereto is used exclusively for transporting clean water. In this way, clean water supply and sewage recycling can be carried out simultaneously in the same connector through two independent flow channels without interfering with each other.

[0032] As another preferred embodiment, in order to simplify the manufacturing process and improve the overall structure, the pin 2, water supply pipe 5 and second exhaust pipe 6 on the nozzle water outlet pipe 3 can be manufactured using an integral molding technology, for example, by injection molding as a single integral component. Similarly, the contact plate 8, first exhaust pipe 4 and second water supply pipe 7 on the water pump end connector 1 can also be integrally molded on the housing of the water pump end connector 1. This design reduces the number of parts and assembly steps, thereby reducing production costs and improving product reliability.

[0033] Working principle: When it is necessary to connect the water supply equipment and the water terminal, the operator holds the nozzle outlet pipe 3, aligns the plug part with the docking chamber of the water pump end connector 1 and pushes it in. During the pushing process, thanks to the guiding insertion cooperation between the first water supply pipe 5 and the second water supply pipe 7, as well as the second exhaust pipe 6 and the first exhaust pipe 4, the pipes at both ends of the male and female ends will automatically align and be inserted smoothly. As the nozzle outlet pipe 3 is continuously pushed in, the sealing ring 9 surrounding the first water supply pipe 5 and the second exhaust pipe 6 will contact the pipe openings of the second water supply pipe 7 and the first exhaust pipe 4 and be radially compressed, thereby forming a reliable fluid seal at the docking interface. Almost at the same time, or slightly later than the time when the seal is formed, the end of the pin 2 fixed on the nozzle outlet pipe 3 will travel to the bottom of the docking chamber and abut against the contact plate 8 fixed there. When the pin 2 is fully in contact with the contact plate 8, the control circuit is turned on, and the water pump receives the start signal and starts working. At this time, clean water is delivered to the nozzle outlet pipe 3 for user use through the water supply channel connected by the second water supply pipe 7 and the first water supply pipe 5. Meanwhile, the waste gas or sewage generated by the system can be drawn back to the recycling equipment through the exhaust channel connected by the first exhaust pipe 4 and the second exhaust pipe 6. The entire process of water supply, exhaust and electric control start can be completed simultaneously with a simple plug-in and plug-out action, which greatly simplifies the operation. With the structural design of sealing first and then powering on, the safety of operation is ensured.
