Water outlet spray head assembly with ventilation hole for water heater

Abstract

The invention relates to a water outlet spray head assembly with a ventilation hole for a water heater. The water outlet spray head assembly comprises a spray rod (91) and a spray head (92) fixed at the upper end of the spray rod (91), wherein the inclined angle of the spray rod (91) is adjustable, so that the height and the water spraying angle of the spray head (92) can be adjusted; the spray rod (91) is in rotatable matching connection with the side wall of a rotary driving box body (3) through a supporting rotating shaft (931) at the lower end of the spray rod (91), and a gear disk (93) is fixedly arranged at the inner end part, extending into the inner cavity of the rotary driving box body (3), of the supporting rotating shaft (931) so as to be meshed with a driving rack part (82) of a transmission member (8) moving up and down.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a water heater water outlet nozzle assembly with ventilation holes. 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 unde...

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
