Control valve housing provided with water outlet nozzle, control valve, faucet, and water outlet device

Abstract

A control valve housing provided with a water outlet nozzle, a control valve, a faucet, and a water outlet device. The water outlet nozzle protrudes out of the outer surface of the control valve housing; a channel communicated with the interior of the housing is arranged in the water outlet nozzle; and the channel of the water outlet nozzle is configured to be communicated with a mixing cavity of a valve plate control assembly. Therefore, water flow can directly flow out of the water outlet nozzle after flowing in from a water inlet at the bottom of a valve core; after the control valve housing is assembled to the faucet, water flows out from the water outlet nozzle and can directly flow out through a water outlet path of a spout of the faucet; water output switching through a hose is not needed, thereby avoiding unsmooth water outputting; a hose mounting space does not need to be reserved in the faucet, and the valve core does not need to be arranged above the spout of a faucet body, such that the height difference between a faucet lever and the spout is greatly reduced, and the height of the faucet body is reduced, thereby making the faucet structure more compact, and reducing the production costs of the faucet.

Description

Control valve housing with water outlet, control valve, faucet and water outlet device Technical Field

[0001] The present invention relates to the technical field of faucets, and in particular to a control valve outer shell provided with a water outlet, a control valve, a faucet and a water outlet device. Background Art

[0002] The valve core is a key component in the faucet. The action of the valve core controls the water flow and water temperature. The existing valve core is usually provided with a water inlet and a water outlet at the bottom of the valve seat. Water flows in through the bottom water inlet, and after the water flow or water temperature is adjusted by the control valve plate inside the valve core, it flows out from the bottom water outlet and then flows out of the faucet through the water outlet hose. For faucets with a water outlet arm, the use of the above valve core has the following disadvantages:

[0003] 1. Since the water outlet is set on the bottom valve seat, it needs to be connected to the water outlet of the faucet through a hose. The assembly is relatively complicated, and space for the hose installation needs to be reserved inside the faucet, which makes the faucet body larger and the cost increased.

[0004] 2. Since the water outlet of the valve core is set on the bottom valve seat, in order to facilitate the installation of the hose, the valve core is usually set above the water inlet end of the water outlet of the faucet body, which increases the height of the faucet body and leads to increased costs. At the same time, it causes a greater height difference between the faucet handle and the water outlet, making the overall faucet structure not compact.

[0005] 3. Through the transfer of the hose, the hose needs to be bent inside the faucet body, which may easily cause the hose to be squeezed and cause poor water flow.

[0101] In this embodiment, the first water outlet 104 of the shell 100 is used to connect to the water outlet pipe of the faucet. After the cold water and hot water enter the mixing chamber 510 and mix, they can flow out from the water outlet channel 703, then enter the chamber 105 between the base 700 and the shell 100, and finally flow out from the first water outlet 104 of the shell 100. The water only passes through the interior of the valve core 1000, does not pass through the valve core mounting seat, and does not contact the outer shell of the faucet. The water enters from the inside of the valve core 1000 and exits from the inside of the valve core, which can reduce the requirements for the material of the valve core mounting seat or the faucet and reduce costs.

[0102] 13 and 14 , further, a threaded sleeve 717 is provided at the hot water inlet 705 and the cold water inlet 707. The threaded sleeve 717 is annular in structure and has internal threads. The threaded sleeve 717 is used to connect to an external hot water pipe or cold water pipe, which can improve the sealing effect and prevent water leakage. Furthermore, the peripheral wall of the hot water inlet 705 and the cold water inlet 707 extends downward to form a mounting portion 719. The mounting portion 719 is annular in structure and is located below the threaded sleeve 717. During installation, the mounting portion 719 can limit the hot water pipe or cold water pipe, which can facilitate the alignment of the hot water pipe or cold water pipe with the threaded sleeve 717 and facilitate installation. Furthermore, a sealing ring can be provided below the threaded sleeve 717 to improve the sealing effect.

[0103] 20 , the water outlet channel 703 further includes a first section 721 and a second section 722. The cross-sections of the first section 721 and the second section 722 are L-shaped. The first section 721 extends vertically and horizontally, and the second section 722 is located below the first section 721. The upper end of the first section 721 forms the mixed water inlet 708, and the end of the second section 722 forms the mixed water outlet 709. The structure of the water outlet channel 703 is simple and can be easily processed.

[0104] 19 , in some embodiments, the width of the second section 722 gradually increases toward the mixed water outlet 709 , thereby increasing the volume of the second section 722 and ensuring smooth water flow. Specifically, the cross-section of the second section 722 is triangular. It should be noted that the width of the second section 722 is horizontal.

[0105] Further, referring to Figure 15, the shell 100 includes a first annular portion 101 and a second annular portion 102. The second annular portion 102 is located on the outer periphery of the first annular portion 101.

The outer diameter of the upper part of the base 700 is smaller than the outer diameter of the lower part of the base 700. The first annular portion 101 is sleeved on the outer periphery of the upper part of the base 700, and the second annular portion 102 is sleeved on the outer periphery of the lower part of the base 700. 4 and 7 , the base 700 is provided with a first annular groove 723 and a second annular groove 724. The mixed water outlet 709 is located between the first annular groove 723 and the second annular groove 724. A first sealing ring 712 is provided in the first annular groove 723, and a second sealing ring 713 is provided in the second annular groove 724. The first sealing ring 712 is in sealing engagement with the inner circumferential wall of the first annular portion 101, and the second sealing ring 713 is in sealing engagement with the inner circumferential wall of the second annular portion 102. The second sealing ring 713 is located below the first sealing ring 712. This embodiment provides a good sealing effect and can prevent water from leaking directly from the chamber 105 to the exterior of the valve core 1000.

[0106] In this embodiment, by providing a first annular portion 101 and a second annular portion 102 on the shell 100, the first annular portion 101 surrounds the upper portion of the base 700, and the second annular portion 102 surrounds the lower portion of the base 700, and then the first sealing ring 712 and the second sealing ring 713 are used to seal the chamber 105 between the shell 100 and the base 700, the sealing effect can be improved to prevent water from leaking to the outside of the valve core 1000.

The water outlet pipe is connected to the first water outlet 104 of the shell 100. The faucet has the above-mentioned technical effects. It can be understood that since the valve core 1000 discharges water from the side, the first water outlet 104 is aligned with the water outlet pipe, and the water outlet pipe can be conveniently connected to the first water outlet 104. The water does not directly contact the outer shell of the faucet, which can reduce the requirements for the faucet material and reduce costs.
