Dust-proof speed-adjustable water outlet nozzle assembly for water heater

Abstract

The invention discloses a dust-proof speed-adjustable water outlet nozzle assembly for a water heater. The dust-proof speed-adjustable water outlet nozzle assembly comprises a spray rod (91) and a nozzle (92) fixed at the upper end of the spray rod (91), wherein the inclination angle of the spray rod (91) is adjustable, so that the height and water spraying angle of the nozzle (92) can be adjusted; the spray rod (91) is in rotatable fit connection with the side wall of a rotary drive cabinet (3) through a supporting rotating shaft (931) at the lower end of the spray rod (91); and a gear disk (93) used for being engaged with a drive rack part (82) of an up-and-down moving transmission part (8) is fixedly arranged at the inner end part, stretching into the inner cavity of the rotary drive cabinet (3), of the supporting rotating shaft (931).

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a dust-proof and speed-adjustable water heater outlet nozzle assembly. Background technique [0002] In the application of the water heater, the spray rod with adjustable angle is often used. The angle adjustment of this water spray rod can adjust the angle and position of water spray. [0003] The angle adjustment of some water spray rods is often carried out manually now. This manual adjustment is easy to cause inconvenience in use, and due to factors such as height, this adjustment often easily causes operational danger. Moreover, it is easy to cause the locking failure of the angle adjusting device during the long-term use, making it difficult to maintain the adjustment angle. However, in 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 source u...

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
