Insertion pipe valve element capable of being connected through hose and faucet

Abstract

A pipe inserting valve element capable of being connected through a hose comprises a valve shell, a valve block module and a valve handle, a water outlet communicated with a water outlet cavity is formed in the side portion of the valve shell, a water guiding connector fixed to the valve shell is arranged at the water outlet, and the water guiding connector can be directly connected with a water outlet pipe used for supplying water outwards. Due to the fact that the water outlet flow channel is further formed in the water guide connector, water flow flowing out of the water outlet needs to impact on the water guide connector firstly and then flows to the water outlet pipe through the water outlet flow channel of the water guide connector, impact force formed by the water flow in the valve shell cannot directly act on the end portion of the water outlet pipe, and the water outlet pipe is not damaged. According to the faucet with the intubation tube valve element, the defect that in the prior art, due to the fact that hose connection is adopted, the end of the water outlet pipe has no stress point, and the water outlet pipe is prone to falling off outwards due to water flow impact is overcome, the water outlet pipe can also be connected through the hose, and therefore the manufacturing cost and the assembling difficulty of the faucet with the intubation tube valve element are reduced. In addition, the utility model further relates to a faucet with the intubation tube valve element.

Description

Technical Field

[0001] The utility model relates to the technical field of faucet valve cores, in particular to an insertion valve core that can be connected by a hose, and also relates to a faucet with the aforementioned insertion valve core. Background Art

[0002] With the improvement of living standards, people pay more and more attention to the pursuit of health. The cleanliness of drinking water is a very important item among them. To prevent heavy metals in drinking water from exceeding the standard, most traditional faucets are made of copper or stainless steel to achieve the purpose of lead-free. However, copper and stainless steel are expensive, the production cost is high, and the production time is long, resulting in high costs and low product competitiveness. Therefore, basin faucets on the market usually adopt integral alloy molding. When the lead element in the alloy contacts the air, the surface will oxidize to form a protective film. However, water can cause the lead protective film to fall off, resulting in the precipitation of lead elements in the faucet. The lead element contained in this faucet material makes the lead content in the water flowing through the faucet exceed the standard and thus become toxic. Therefore, lead-free faucets have emerged on the market.

[0003] For example, the Chinese utility model patent "An Insertion Valve Core and Valve Core Group That Can Be Connected by a Hose" with the application number 202322952467.3 (publication number CN221170819U) discloses such a lead-free faucet. The valve core of this faucet includes a valve shell and an upper cover provided on the top of the valve shell. By setting a valve core cavity in the valve shell and arranging a valve plate module for controlling the opening and closing of the water path in this valve core cavity, an annular water outlet cavity surrounding the valve core cavity is also arranged in the valve shell, and a connection channel is arranged on the valve shell to communicate the valve core cavity and the water outlet cavity. Moreover, a jack for inserting and conducting the water outlet cavity by the water outlet pipe is arranged on the side wall of the valve shell. We can set a water outlet pipe that can directly communicate with the water outlet end of the faucet in this jack, so that the entire water flow channel can directly discharge water without contacting the faucet shell, and thus the faucet can achieve a lead-free design.

[0004] However, there is also a problem here. Since the water outlet pipe here is horizontally inserted into the jack on the side of the valve shell from the outside to the inside, and the water in the valve shell also flows horizontally and impacts the water outlet pipe, the water outlet pipe here will be impacted by the water flow and is only suitable for connecting to a rigid pipe. Because one end of the rigid pipe is inserted into the valve shell, and the other end is fixed at the water outlet of the faucet, both ends have force-bearing points, so it will not be affected by the water flow impact force. However, if a hose is used for connection, because the hose can be bent and its two ends have no force-bearing points, the hose directly connected to the jack on the side of the valve shell will be strongly impacted by the water flow and move outward, and finally the end of the hose will be separated from the jack of the valve shell, affecting normal use.

[0005] Therefore, how to provide an insertion valve core with a compact and reasonable structure that can be connected by a hose, and enable the faucet using this valve core to achieve lead-free is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0012] In order to better form the valve core cavity and the water outlet cavity between the upper shell and the base, preferably, a downward extending annular wall is formed inside the upper shell, and the base includes a first annular platform and a second annular platform extending upward, the first annular platform is adapted to the inner circumferential surface of the upper shell, and the second annular platform is adapted to the inner circumferential surface of the annular wall, the second annular platform and the annular wall together form the aforementioned valve core cavity, and the water outlet cavity is formed between the outer wall of the upper shell and the annular wall, and the base is also provided with a connecting channel for conducting the valve core cavity and the water outlet cavity.

[0013] In order to achieve good sealing performance for both the valve core cavity and the water outlet cavity, preferably, a second sealing member is provided between the first annular platform and the inner circumferential surface of the upper shell, and a third sealing member is provided between the second annular platform and the annular wall.

[0014] In order to better control the switching water outlet of the valve plate module, so that it has manual mode and automatic mode and can be switched quickly, preferably, the valve plate module includes a rotor, a dial, a movable valve plate and a fixed valve plate arranged in sequence, the rotor can be rotatably arranged on the valve housing, the valve handle is hinged to the rotor and can swing back and forth to drive the dial to move, the dial is constrained to the bottom of the rotor and can rotate with the rotor and can slide relative to the rotor, the movable valve plate is fixed on the bottom surface of the dial, the fixed valve plate is fixed to the bottom of the valve core cavity and receives the water flow coming in from the water inlet hole, the rotation of the movable valve plate is used to adjust the mixing ratio of cold water and hot water, and the sliding of the movable valve plate is used to close or let in water.

[0017] Compared with the prior art, the advantages of the present utility model are as follows: By providing a water outlet communicating with the water outlet cavity on the side of the valve housing, and providing a water guide joint fixed on the valve housing at the water outlet, the water guide joint here can be firmly pressed on the valve housing by a component provided on the faucet housing, and the water guide joint can directly connect to the water outlet pipe for supplying water outward. Since a water outlet flow channel is also formed inside the water guide joint, the water flowing out from the water outlet needs to impact on the water guide joint first, and then flow to the water outlet pipe through the water outlet flow channel of the water guide joint. Therefore, the impact force formed by the water flow in the valve housing will not directly act on the end of the water outlet pipe, but first impact on the water guide joint, effectively avoiding the drawback in the prior art that due to the use of a hose connection, there is no force-bearing point at the end of the water outlet pipe, and it is easy for the water outlet pipe to be directly impacted by the water flow and fall off outward. This enables the water outlet pipe here to also use a hose connection, thereby reducing the manufacturing cost and assembly difficulty of the faucet applying this inserted pipe valve core. In addition, a faucet applying this inserted pipe valve core is also involved here. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Furthermore, in order to optimize the overall structure and installation layout of the valve housing 1, refer to Figures 2 to 4 As shown, in this embodiment, the valve housing 1 includes an upper housing 11 and a base 12. The upper housing 11 is detachably connected to the top of the base 12 through a snap groove connection. The upper end of the valve handle 3 is exposed on the top of the upper housing 11. The outlet cavity 1c is formed inside the upper housing 11. The inlet hole 1b is opened on the base 12, and the outlet 1d is opened on the side of the upper housing 11.

[0031] Meanwhile, in order to better form the valve core cavity 1a and the outlet cavity 1c between the upper housing 11 and the base 12, refer to Figure 5As shown, in this embodiment, an annular wall 11a extending downward is formed inside the upper shell 11.

A connecting channel 12c for communicating the valve core cavity 1a and the water outlet cavity 1c is also provided on the base 12.

[0032] In addition, in order to enable both the valve core cavity 1a and the water outlet cavity 1c to achieve good sealing performance, a second sealing member 7 for sealing is further provided between the first annular platform 12a and the inner peripheral surface of the upper shell 11, and a third sealing member 8 for sealing is provided between the second annular platform 12b and the annular wall 11a.

[0033] In this embodiment, in order to better control the switching of the water output of the valve plate module 2, so that it has a manual mode and an automatic mode and can be quickly switched, refer to Figure 3 and Figure 4 As shown, the valve plate module 2 includes a rotor 2a, a dial 2b, a movable valve plate 2c and a fixed valve plate 2d arranged in sequence.

Correspondingly, generally two water inlet holes 1b will be provided here, namely a hot water inlet hole and a cold water inlet hole.

[0034] In addition, in this embodiment, a faucet capable of achieving lead-free is also provided. The faucet includes a faucet housing 9 and an insertion valve core. Specifically refer to Figure 6 and Figure 7 As shown, the insertion valve core is installed inside the faucet housing 9. In addition, a water outlet pipe 5 built in the faucet housing 9 is also included. The first end of the water outlet pipe 5 is connected to the water guiding joint 4. A fixing member 9a for fixing the second end of the water outlet pipe is also provided on the faucet housing 9. Here, the fixing member 9a can be directly provided at the water outlet end of the faucet housing 9. Here, the water outlet pipe 5 can be connected by a flexible pipe or a rigid pipe. Since the water outlet pipe 5 is directly connected between the water guiding joint 4 and the fixing member 9a, the water flow directly flows from the water outlet pipe 5 to the water outlet end of the faucet, so that the faucet can achieve lead-free.

[0035] In order to firmly fix the water guide joint 4 here on the valve housing 1 and make it more convenient to assemble the plug valve core here into the faucet housing 9, refer to Figure 7 As shown, a ring-shaped pressing sleeve 9b is provided inside the faucet housing 9. The pressing sleeve 9b is sleeved on the valve housing 1 and can press on the water guide joint 4 to limit the upward detachment of the water guide joint 4. A pressing cover 9c that can limit the upward detachment of the pressing sleeve 9b is also provided at the top of the pressing sleeve 9b. The pressing cover 9c is detachably connected to the faucet housing 9 by threaded connection.

[0036] It also needs to be additionally explained here: In this embodiment, a water outlet cavity 1c is formed inside the valve housing 1. By providing a water outlet 1d communicating with the water outlet cavity 1c on the side of the valve housing 1, and by providing a water guide joint 4 fixed on the valve housing 1 at the water outlet 1d, and making the water guide joint 4 here directly connect to the water outlet pipe 5 for supplying water outward. Since a water flow channel 4a is also formed inside the water guide joint 4 here, the water flow flowing out from the water outlet 1d needs to first impact on the water guide joint 4 and then flow to the water outlet pipe 5 through the water flow channel 4a of the water guide joint 4. Therefore, the impact force formed by the water flow in the valve housing 1 will not directly act on the end of the water outlet pipe 5, avoiding the drawback in the prior art that the end of the water outlet pipe has no force-bearing point due to the use of a hose connection, and it is easy for the water outlet pipe 5 to be detached outward under the impact of the water flow. This enables the water outlet pipe 5 here to also use a hose connection, thereby reducing the manufacturing cost and assembly difficulty of the faucet with this plug valve core.
