Description

Technical Field

[0001] This utility model relates to the field of air pump technology, and in particular to an integrated pump and valve assembly for automobile seats. Background Technology

[0002] In modern car seat design, the application of air pumps is crucial, providing a stable air supply and precise control components for the lumbar support and massage components. Driven by a motor, the air pump generates a continuous airflow, which is delivered through a precisely designed piping system to the airbags in the lumbar support and massage components.

[0003] Traditional massage chairs mainly consist of an air pump, air valves, and tubing connectors. Their core function is to inflate and deflate the air bags. The air pump generates airflow, providing power to the entire system, while the air valves control the flow and direction of the airflow to inflate and deflate the air bags. These components are interconnected via air tubing, forming a complete pneumatic system.

[0004] However, because the air pump and air valve are arranged separately, they need to be connected by a long air tube. This layout not only increases the complexity of the system, but also results in a large space occupation. Summary of the Invention

[0005] The main technical problem to be solved by this utility model is to provide an integrated pump and valve assembly for automobile seats, which integrates the air pump and air valve into one unit, reducing the use of air pipes and saving installation space and cost.

[0006] To solve the above-mentioned technical problems, this utility model provides an integrated pump and valve assembly for automobile seats, including an air pump and an air valve disposed on the air pump. The air valve includes an air passage and a pressure relief assembly. The air passage includes an air inlet, an air outlet and a venting outlet.

[0007] The air inlet is connected to the air pump's inflation port. A one-way valve is provided at the inflation port. When the air pump is inflating, the gas can push the one-way valve to open and allow air to enter through the air inlet.

[0008] The pressure relief assembly is connected to the vent. When the gas valve releases gas, the one-way valve closes, and the gas can push the pressure relief assembly to open the vent for gas release.

[0009] In a preferred embodiment, the vent is provided on one side of the air passage along its length, the vent has a built-in air nozzle, the air nozzle is connected to the air passage, and the pressure relief assembly is used to open or close the air nozzle.

[0010] In a preferred embodiment, there is an air gap between the sidewall of the air passage and the pressure relief assembly, and when the pressure relief assembly opens the air nozzle, gas is discharged through the air gap.

[0011] In a preferred embodiment, the air pump includes a housing that covers the air valve, the air slit communicates with the internal space of the housing, and the housing is provided with a through hole to avoid the air passage;

[0012] The through hole connects to the internal space of the outer shell, and the air passage is fitted with the through hole with a gap, through which gas is discharged.

[0013] In a preferred embodiment, the pressure relief assembly includes a mounting base and an elastic element and a sealing element assembled on the mounting base;

[0014] The two ends of the elastic element abut against the mounting base and the sealing element respectively, and the elastic element pushes against the sealing element so that the sealing element abuts against and closes the air nozzle.

[0015] In a preferred embodiment, the elastic element is a spring.

[0016] In a preferred embodiment, the one-way valve has a Umbrella-shaped structure.

[0017] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0018] 1. By integrating the air pump and air valve into one unit, the pneumatic system structure of traditional massage chairs is greatly optimized. The air pump's inflation port is directly connected to the air passage, reducing the use of air pipes, simplifying the system's complexity, and saving installation space and costs. It has significant advantages in applications with limited installation space.

[0019] 2. A one-way valve is installed at the air pump's inflation port. The function of the one-way valve is to prevent gas in the airway from flowing back into the air pump when the air pump stops working, thus maintaining pressure and adding a massage function mode.

[0020] 3. The design of the pressure relief component can precisely control the gas discharge, improve the efficiency of gas discharge, make the system respond more quickly, and make the massage function more flexible and diverse. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0032] refer to Figures 1-7 This embodiment provides an integrated pump and valve assembly for automotive seats, including an air pump 2 and an air valve 1 disposed on the air pump 2. The air valve 1 includes an air passage 11 and a pressure relief assembly 12. The air passage 11 includes an air inlet 111, an air outlet 112, and a vent 113. Integrating the air pump 2 and the air valve 1 into one unit saves space and cost, reduces the use of air pipes, optimizes the spatial layout, simplifies the system structure, and reduces manufacturing and installation costs.

[0033] like Figure 5 The air inlet 111 is connected to the air inlet 21 of the air pump 2. A one-way valve 22 is provided at the air inlet 21. When the air pump 2 is inflating, the gas can push the one-way valve 22 to open and allow air to enter through the air inlet 111. The pressure relief assembly 12 is connected to the vent 113. When the air valve 1 releases air, the one-way valve 22 closes, and the gas can push the pressure relief assembly 12 to open the vent 113 for air release (e.g., Figure 6 The one-way valve 22 prevents gas backflow when the air pump 2 stops working, and plays a pressure-maintaining role, ensuring that the airbag remains inflated for a short time, thus improving the stability and continuity of the massage function.

[0034] Specifically, the air vent 113 is provided on one side of the air passage 11 along its length (e.g., Figure 3 The vent 113 has a built-in air nozzle 114, which is connected to the air passage 11. The pressure relief assembly 12 is used to open or close the air nozzle 114 (e.g., Figure 4 By designing the vent 113 on one side of the airway 11, the layout of the airway 11 is optimized, making the structure more compact and further saving space. Through the control of the air nozzle 114 by the pressure relief component 12, the gas discharge can be controlled more precisely, and more flexible massage function adjustment can be achieved.

[0035] like Figure 5 An air gap 13 exists between the sidewall of the air passage 11 and the pressure relief assembly 12. When the pressure relief assembly 12 opens the air nozzle 114, gas is discharged through the air gap 13. The design of the air gap 13 provides a smooth discharge path for the gas, ensuring that the gas can be discharged quickly and stably.

[0036] like Figure 1 The air pump 2 includes a housing 23 that covers the air valve 1. The air slit 13 communicates with the internal space of the housing 23. The housing 23 is provided with a through hole 231 that avoids the air passage 11 (e.g., Figure 5The through hole 231 connects to the internal space of the outer casing 23, and the air passage 11 is fitted with the through hole 231 through a gap 232, through which gas is discharged. The design of the outer casing 23 provides protection for the air valve 1, preventing interference from external dust, impurities, etc. The fit between the through hole 231 and the air passage 11 through a gap 232 provides a more reasonable channel for gas discharge, further optimizing the gas discharge efficiency.

[0037] like Figure 2 The pressure relief assembly 12 includes a mounting base 121 and an elastic element 122 and a sealing element 123 assembled on the mounting base 121. The two ends of the elastic element 122 abut against the mounting base 121 and the sealing element 123 respectively. The elastic element 122 pushes against the sealing element 123, causing the sealing element 123 to abut against and close the air nozzle 114. The elastic force of the elastic element 122 (such as a spring) ensures that the sealing element 123 tightly abuts against the air nozzle 114, achieving a reliable seal and preventing gas leakage. The elastic characteristics of the elastic element 122 allow the pressure relief assembly 12 to respond quickly when gas release is needed, flexibly opening the air nozzle 114 to achieve rapid gas discharge.

[0038] The one-way valve 22 has a Umbrella-like structure (e.g., Figure 1 The umbrella-shaped check valve 22 has good sealing performance and fast response capability, and can quickly open when the air pump 2 is charging and quickly close when it is discharging, ensuring unidirectional flow of gas.

[0039] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
