Beneficial effect

1. When the device is in the reset state, the extension assembly is retracted into the inside of the installation seat to hide, so that only the cleaning nozzle inside the installation seat sprays water to clean the dirt during diagnosis and treatment during the cleaning operation. The waste of water resources will not be caused when the dirt is cleaned. When it is necessary to adjust the spraying range of the water flow, it can be realized by directly pulling the extension assembly outward. When the extension assembly is pulled, the pull-out of the extension seat can be positioned by the limit block At the same time, the adaptive block pulled out of the mounting seat can automatically obtain the supply of water source, so that the water flow can also be sprayed, so that the water jet can be widened under the cooperation of the adaptive block pulled out of the mounting seat and the mounting seat The utility model can adapt to the fast flushing and cleaning of different ranges of dirt, which improves the flexibility, adaptability and practicability of the device.

2. Under the action of the return tension spring, when the device is in the reset state, the extension seat is in the state of retracting into the interior of the installation seat, so that under the limit action of the installation seat, the adaptive block installed inside the extension seat will be installed The seat body of the seat is extruded, so that the adaptable block will shrink into the interior of the extended seat, so that the interface parts of the opening and closing channel and the communication channel are misaligned, so that when the water flow enters the device through the water inlet channel, the water flow cannot enter the adaptation block. Inside, the water flow can only pass through the distribution channel a and the main channel in turn, and finally spray out through the cleaning nozzle on the mounting base. It will cause waste of water resources, and it is flexible and convenient to use.

3. When it is necessary to widen the water jet range of the device, it can be realized by simply pulling the extension seat outward. When the extension seat is pulled outward, the adapting block will leak out of the inside of the mounting seat, so that the mounting seat will not adapt to the The use position of the block is limited, and then the adaptive block can be pushed out of the extension seat under the action of the connecting top spring. When the adaptive block is pushed out of the extension seat, the communication channel can coincide with the interface position of the opening and closing channel. Therefore, at this time, the water flow entering the installation seat through the water inlet channel is divided into two parts, one part of which is still sprayed out through the diversion channel a, the main channel, and the cleaning nozzle on the installation seat, and the other part will pass through the diversion channel b and adapt to the Channels and communication channels finally enter the interior of the opening and closing channels and finally spray out from the cleaning nozzle of the adapting block, so that different numbers of adapting blocks can be used by changing the pull-out length of the extension seat, that is, the water spraying range of the device can be adjusted , can adapt to the rapid cleaning and cleaning of different areas of dirt, and has strong adaptability.

4. When the extension seat is pulled out and used, the limit block can position the use length of the extension seat. When the extension seat is pulled out, because the top of the limit block is designed as a right triangle, the limit block is in the outward direction. When pulling, when encountering the limit stop, it can automatically move downward to avoid the limit stop. When the extension seat is pulled out to the required length, after the extension seat is released, the extension seat will have a shunt block under the action of the reset tension spring. The tendency of the wind direction to move, under the action of the avoidance top spring, the limit block can automatically protrude from the inside of the extension seat after the avoidance action is completed, so that the limit block can be engaged with the straight edge of the nearest limit block , so as to realize the positioning of the use length of the extension seat. Under the action of the positioning top spring, the limit stopper can be stably engaged with the limit clamping block, and the setting number of the limit stopper and the adaptive block is the same, that is, every Each of the limit stops can be used accurately corresponding to the corresponding number of adaptable blocks when they are clamped with the straight sides of the limit blocks, and the adjustment is convenient and the positioning is accurate.

5. After the cleaning of the dirt is completed, the extension seat pulled out for use can be quickly reset through the control lever. When the control lever is pulled, the control lever can drive the limit block to move, and the limit block can drive the limit when moving The block moves synchronously to release the clamping relationship with the limit block, so that the wire extension seat can be automatically reset under the action of the reset tension spring, and when the extension seat is reset, the adaptable block can be moved by the inclined chamfer on one side of the block body. The extrusion of the seat body of the mounting seat makes the adaptable block shrink into the interior of the extension seat again, realizing the sealing of the interior of the extension assembly, avoiding the phenomenon of water leakage, and stable use.
