Problems solved by technology

For water purifiers or all built-in flowmeter equipment, it is inconvenient to install with threads, the reliability is low, the production cost is high and the process is complicated by welding. It is convenient but inflexible to use double light rod quick connection. Ordinary plastic sensors are fixed by screws. Poor pressure bearing performance, easy to rust the screws, troublesome maintenance and disassembly

Abstract

The invention discloses a flow sensor and a cleaning instrument with the same. The flow sensor comprises: a first housing defining a first housing cavity opened at two ends, wherein the inlet end of the first housing cavity is adapted to be inserted into a pipe body and provided with a fixed joint; a second housing defining a second housing cavity opened at two ends, wherein the inlet end of the second housing is connected to the outlet end of the first housing in a clamped mode, and the first housing cavity is communicated with the second housing cavity; a sensing module arranged in the second housing cavity; a clamping jaw clamped on the fixed joint and movable between a first position where the clamping jaw is pressed by the fixed joint and a second position where the clamping jaw is released by the fixed joint, wherein the pipe body is adapted to extend into the first housing through the clamping jaw, the clamping jaw can be moved from the second position to the first position as the tube body moves outwardly away from the second housing. The flow sensor has a double-quick-connection structure, can realize quick installation, is more convenient and firm in installation, and isimproved in reliability and simple in maintenance and replacement.

Description

technical field [0001] The invention relates to the technical field of water treatment, more specifically, to a flow sensor and a cleaning instrument with the same. Background technique [0002] Flow sensors are required in water purifiers, water systems, direct drinking fountains, and cleaning appliances to drive (start and stop signals) the equipment to start or do flow measurement. The multi-flow sensor in the related art is a metal part with a Hall sensing element or a plastic with a Hall sensing element, and the interface method is threaded connection, double light bar type quick connection or metal welding. For water purifiers or all built-in flowmeter equipment, it is inconvenient to install with threads, the reliability is low, the production cost is high and the process is complicated by welding. It is convenient but inflexible to use double light rod quick connection. Ordinary plastic sensors are fixed by screws. The pressure bearing performance is poor, the screw...
