Description

Tap head

Technical Field

The utility model relates to the technical field of waterways, in particular to a faucet.

Background

As people's demands for quality of life are increasing, faucets have become an indispensable commodity.

In order to enhance the user's use experience, control panels are provided within some faucets. In this way, the faucet can achieve a more intelligent function. There is typically a large amount of water vapor around the faucet to prevent the water vapor from contacting the control panel, thereby causing shorting and/or corrosion problems with the control panel, and the faucet panel and bottom housing surrounding the control panel need to be sealed with a sealant. That is, the faucet panel and the bottom housing are sealed by a glue filling process. Thus, the waterproof performance between the faucet panel and the bottom cover is higher, so that the control panel is ensured to work normally.

However, the cost of the glue filling process is high and the market competitiveness of the tap is poor. And moreover, the glue filling process is complex, the quality control is difficult, and the batch consistency of the faucet is poor. And, because the sealant needs a certain curing time, the production period of the tap is longer, and the production efficiency is lower.

The faucet panel 100 and the bottom cover 300 can clamp the sealing ring 500, thereby realizing sealing and waterproof functions.

Accordingly, the faucet provided by the embodiment of the utility model, the faucet panel 100 and the bottom housing 300 can be sealed by the sealing ring 500. Compared with the sealant, the sealing ring 500 can be solid, so that the process of disposing the sealing ring 500 between the faucet panel 100 and the bottom housing 300 is simple. The sealing ring 500 can be manufactured in batches, so that quality control is easier, and the batch consistency of the faucet is better. The cost of the seal ring 500 manufactured in batch can be greatly reduced, and the market competitiveness of the faucet is better. Further, the seal ring 500 can be of standard type, which can further reduce cost. And, the same sealing ring 500 can be adopted for different types of taps, so that the variety of purchase can be reduced. And, sealing ring 500 can realize sealing after being connected, and it need not the curing time, and tap's production cycle is shorter, and production efficiency is higher.

Illustratively, the edge of the bottom surface of the faucet panel 100 may be provided with a downwardly extending bead 110. The bead ring 110 may extend toward the bottom cover 300. The bead ring 110 may be inserted into the recess 310. The sealing ring 500 may be clamped between the inner sidewall of the recess 310 and the outer side of the bead ring 110. By inserting the bead ring 110 into the recess 310, the guiding and limiting effects between the faucet panel 100 and the bottom cover 300 are good, so that the faucet panel 100 and the bottom cover 300 are respectively positioned at the expected positions, and the performance of the faucet is stable.

Illustratively, the bead ring 110 may be provided with a step 120 on an outer sidewall thereof. The step 120 may surround the outer sidewall of the bead ring 110. The step 120 may be spaced apart from the bottom surface of the bead ring 110. The step 120 may divide the bead ring 110 into a large-sized portion 111 and a small-sized portion 112. The large-sized portion 111 may be located at an upper portion of the step 120. The small-sized portion 112 may be located at a lower portion of the step 120. A step 120 may be formed between the large-sized portion 111 and the small-sized portion 112. The seal ring 500 may be fitted over the small-sized portion 112. During the process of connecting the faucet panel 100 and the bottom housing 300, the small-sized portion 112 may be inserted into the recess 310 in advance as compared to the large-sized portion 111. In this way, the seal ring 500 may move toward the large-sized portion 111 by the inner sidewall of the recess 310 and the outer side surface of the small-sized portion 112. The step 120 may play a limiting role on the sealing ring 500, thereby preventing the sealing ring 500 from being separated from the small-sized portion 112, and further ensuring a good sealing effect between the faucet panel 100 and the bottom cover 300.

The shape of the plurality of connecting arms 810 may be arbitrary, including but not limited to straight or folded. Illustratively, the plurality of connecting arms 810 may be curved. So configured, the plurality of connection arms 810 are long in length so as to be appropriately movable. Accordingly, the accuracy of the positions between the plurality of connection arms 810 and the fixing part 150 may be appropriately lowered, so that the machining accuracy and the mounting accuracy of the faucet may be lowered. The user can control the key 800 so that the corresponding parts on the control board 200 can be triggered, and thus the functions of opening and closing the tap can be realized.

Illustratively, the fixing portion 150 may include a fixing post. The end of the connection arm 810 may be provided with a fixing sleeve 811. The fixing sleeve 811 may be fit over the fixing post with an interference fit. In this way, the connection strength between the connection arm 810 and the fixing portion 150 is high, so that the key 800 can be positioned at a desired position. In addition, the connecting arm 810 is connected to and disconnected from the fixing portion 150 without using a tool, so that the operation is convenient.

The following provides a tap mounting procedure: first, the control board 200 may be accommodated in the recess 310. The cable connected to the control board 200 may then be threaded out of the threading hole on the bottom cover 300. The sealing plug 700 may then be sleeved to the cable. The sealing plug 700 may then be plugged into the threaded bore. In the above process, the key 800 may be connected to the tap panel 100. The gasket 500 may then be placed over the faucet faceplate 100. The faucet panel 100 can then be connected to the bottom housing 300. In this way, the faucet panel 100 and the bottom housing 300 can clamp the gasket 500, thereby sealing. Finally, the faucet panel 100 may be covered over the mounting opening 410. Thus, the faucet installation is completed.
