A new type of seat electric height control valve

Abstract

This utility model discloses a novel electrically controlled seat height valve, including a main valve housing. An operation button is centrally mounted on the top of the main valve housing, and an electronic switch for activating an air pump is located on one side of the main valve housing. The main valve housing has two sets of trigger components that can be used to open the exhaust elastic reset sealing assembly and the intake elastic reset sealing assembly, respectively. Only one trigger component can be activated by reciprocating the operation button. The operation button also has a trigger structure that triggers the electronic switch synchronously with the intake. In addition to controlling intake, exhaust, and discharge, this height valve integrates the function of controlling and activating the air pump in conjunction with the trigger control function near the intake. By triggering the electronic switch controlling the air pump while controlling the intake, the air pump is activated, ensuring sufficient air supply and good intake effect, thereby better controlling and adjusting the seat height.

An exhaust chamber 15, an air outlet 4, and an air inlet chamber 17 are sequentially arranged at the bottom of the valve main housing 1. Inside the valve main housing 1 is a connecting cavity 16 that communicates with the exhaust chamber 15, the air outlet 4, and the air inlet chamber 17. An exhaust elastic reset sealing assembly is provided within the exhaust chamber 15 to seal the connection between the connecting cavity 16 and the exhaust chamber 15. An air inlet chamber 17 is provided with a sealing assembly for sealing... An intake elastic reset sealing assembly is provided at the connection between the intake chamber 17 and the connecting chamber 16. An electronic switch 6 for starting the air pump is provided on one side of the valve main housing 1. Two sets of trigger components 9 are provided on the valve main housing 1, which can be used to open the exhaust elastic reset sealing assembly and the intake elastic reset sealing assembly respectively. A pair of trigger components 9 are distributed at both ends below the operation button 2, and only one trigger component 9 can be activated by reciprocating the operation button 2. The operation button 2 is also provided with a trigger structure that is triggered synchronously with the intake and is used to trigger the electronic switch 6.
