Water heater water outflow sprayer assembly with dust prevention and limiting functions

Abstract

The invention provides a water heater water outflow sprayer assembly with dust prevention and limiting functions. The water heater water outflow sprayer assembly comprises a spray rod (91) and a sprayer (92) fixed to the upper end of the spray rod (91). The inclination angle of the spray rod (91) can be adjusted, so that the height and the water spray angle of the sprayer (92) are adjusted. The spray rod (91) is rotationally connected with the side wall of a rotary drive box (3) in a matched manner through a supporting rotary shaft (931) at the lower end of the spray rod (91), and a gear disc (93) is fixedly arranged at the inner end, stretching into an inner cavity of the rotary drive box (3), of the supporting rotary shaft (931) and used for being engaged with a driving rack part (82) vertically moving a drive part (8).

Description

Technical field [0001] The invention relates to the field of water heaters, in particular to a water heater outlet nozzle assembly capable of preventing dust and limiting positions. Background technique [0002] In the application of water heaters, spray rods with adjustable angles are often used. The angle adjustment of the water spray rod can adjust the angle and position of the water spray. [0003] The angle adjustment of some current sprinklers is often done manually. This kind of manual adjustment is easy to cause inconvenience. Due to factors such as height, this kind of adjustment tends to cause operational hazards. Moreover, in the long-term use process, it is easy to cause the locking failure of the angle adjustment device, which makes it difficult to maintain the adjustment angle. For applications that use power to adjust the angle, the locking is often performed by a mechanism directly connected to the power source, which is likely to cause an impact on the power sou...

AI Technical Summary

Problems solved by technology

This manual adjustment is easy to cause inconvenience in use, and due to factors such as height, this adjustment is often easy to cause operational hazards

Moreover, in the long-term process of use, it is easy to cause the locking failure of the angle adjustment device, which makes it difficult to maintain the adjustment angle.

However, for applications that use power to adjust the angle, the locking is often performed by a mechanism that is directly connected to the power source, which is likely to cause an impact on the power source under the impact of an external force.

Moreover, the unlocking of the locking mechanism is often driven by an additional power source, which easily causes an increase in cost and an increase in maintenance cost
