Description

Technical Field

[0001] This utility model relates to the field of valve core technology, and more specifically, to a valve core assembly and a water outlet device. Background Technology

[0002] The valve core is mainly used in water outlet devices to control the water flow and to switch the valve on and off.

[0003] Currently, utility model patent application number 201920125385.2 discloses a valve core assembly for a faucet. It includes a main body with a cold water connection pipe, a hot water connection pipe, and a water outlet connection port. The main body includes a valve body and a valve seat connected to the bottom of the valve body, with the water outlet connection port penetrating the end face of the valve body facing the valve seat. It also includes a water outlet assembly, which includes a connecting core, an installation pipe, and a water outlet hose. One end of the connecting core is embedded inside the water outlet connection port, the installation pipe is disposed on the side wall of the connecting core and communicates with the inner cavity of the connecting core, and the water outlet hose is sleeved on the installation pipe.

[0004] The installation process is as follows: First, place the valve seat inside the valve core cavity of the faucet; then, extend the water outlet assembly from the faucet head. When the connecting core is above the valve seat, rotate the water outlet hose to make the connecting core vertical; then, align the water outlet connection port on the valve body with the connecting core, and move the valve body to one side of the connecting core until the top of the connecting core extends into the water outlet connection port, and the valve body is connected to the valve seat.

[0005] However, because the connection between the connecting core and the outlet pipe is a lateral seal on the circumferential surface, and to ensure a good seal, the inner diameter of the outlet pipe is only slightly larger than the outer diameter of the connecting core. Since the connecting core is flexibly placed inside the valve core cavity along with the outlet pipe, it is not securely positioned within the valve core cavity. This means that during the valve core assembly and pressing process, the connecting core is easily affected by the flexible outlet pipe, causing it to shift or tilt, thus preventing it from being directly inserted into the outlet pipe connection.

[0016] Furthermore, the connection port between the support arm and the valve core cavity is positioned opposite to the opening of the channel.

[0017] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0030] Example

[0031] Combination Figures 1 to 8 As shown, this embodiment provides a valve core assembly, including a valve core 1 with a lower water outlet channel 7, and a valve seat 2, an adapter 3, and a sealing element 4 connected to the bottom of the valve core 1; a through groove 6 is provided between the base 5 of the valve core 1 and the valve seat 2, with one side penetrating the side wall of the base 5 and the valve seat 2; the through groove 6 communicates with the lower water outlet channel 7; the adapter 3 has two intersecting connecting ends, one end of which is sealed to the lower water outlet channel 7, and the other end is placed on the through groove 6 for connecting a water outlet pipe 8;

[0032] The lower water outlet channel 7 has a first stepped surface 9 on its end face; one end of the adapter 3 has a protrusion 10, and the bottom of the protrusion 10 has a second stepped surface 11 opposite to the first stepped surface 9; the sealing member 4 is sleeved on the protrusion 10, and its outer periphery has a guide sealing surface 12 whose outer diameter gradually increases from top to bottom.

[0033] Among them, such as Figure 3 and Figure 5 As shown, the first stepped surface 9 and the second stepped surface 11 refer to the bottom planar structures formed on the end face of the lower water outlet channel 7 and the protruding part 10 of the adapter, specifically an annular platform. Firstly, the stepped surfaces can limit the axial displacement of the adapter 3. For example... Figure 6 As shown, the guide sealing surface 12 refers to the conical or arc-shaped surface on the outer periphery of the seal 4, which can be made of rubber through molding. The conical or arc-shaped guide surface can play a certain guiding role when one end of the adapter 3 is inserted into the water outlet channel. Therefore, the inner diameter of the water outlet channel can be set larger than the outer diameter of one end of the adapter 3. In this way, even if one end of the adapter 3 is offset or skewed, it can still be adapted to the water outlet channel under the action of the conical or arc-shaped guide surface. At the same time, the setting of the first step surface 9 and the second step surface 11, when the adapter 3 is inserted into the water outlet channel, due to the setting of the guide sealing surface 12 of the seal 4 which gradually increases in size from top to bottom, the upper part of the seal 4 is at least partially placed between the inner wall of the water outlet channel and the outer wall of the protrusion 10 to form a radial seal; while the lower part of the seal 4 forms an end face seal between the first step surface 9 and the second step surface 11. The double seal makes the sealing between the adapter 3 and the water outlet channel better. This method reduces the requirements for installation accuracy; the gradually expanding design of the guide sealing surface 12 allows for a certain range of positional deviations, automatically corrects the alignment during the pressing process, and forms multiple sealing effects.

[0034] Specifically, such as Figures 1 to 3As shown, the lower water outlet channel 7 at the bottom of the valve core 1 extends outward through a through groove 6 that passes through the base 5 and the valve seat 2 on one side. The adapter 3 is L-shaped, and one end of it is sealed to the lower water outlet channel 7 through a sealing member 4 of the protrusion 10. Specifically, the sealing member 4 is sleeved on the outside of the protrusion 10, and its guide sealing surface 12 generates radial compression with the inner wall of the channel during assembly, thereby generating axial compression between the first step surface 9 and the second step surface 11. When the water outlet pipe 8 is connected to the other end of the adapter 3, water flows from the lower water outlet channel 7 through the interior of the adapter 3 to the water outlet pipe 8.

[0035] This application further proposes that the adapter 3 is provided with a limiting part 13, and the valve seat 2 is provided with a limiting groove 14 adapted to the limiting part 13. Figure 5 and Figure 8 As shown, the limiting part 13 refers to the protrusion or recess structure formed on the outer surface of the adapter 3, which is used to form a physical constraint with the limiting groove 14 on the valve seat 2. The limiting groove 14 refers to the groove or protrusion with a matching shape provided on the inner wall of the valve seat 2. Specifically, it can be implemented by a groove structure corresponding to the geometric dimensions of the limiting part 13, and its function is to limit the adapter 3 from shifting or moving during the assembly process.

[0036] This application further includes Figure 7 and Figure 8 As shown, a protruding connecting part 15 is provided at the bottom of the base 5 along the axis of the water inlet channel, and a connecting groove 16 adapted to the connecting part 15 is provided on the valve seat 2. The connecting part 15 and the connecting groove 16 form a radial seal through a sealing ring.

[0037] The connecting part 15 refers to the protruding structure extending along the axis of the water inlet channel at the bottom of the base 5. Specifically, it can be a cylindrical protrusion, and its function is to form an axial positioning fit with the connecting groove 16 of the valve seat 2. The connecting groove 16 refers to the recessed structure on the surface of the valve seat 2 that matches the shape of the connecting part 15, and its function is to provide a stable assembly space for the connecting part 15. Radial sealing refers to the sealing effect achieved by the compression deformation of the sealing ring in a direction perpendicular to the axis. Specifically, an O-ring can be used to form a circumferential seal between the outer wall of the connecting part 15 and the inner wall of the connecting groove 16.

[0038] This application further proposes that the outlet pipe 8 is a flexible or rigid pipe.

[0039] Among them, flexible pipes refer to pipes with the ability to bend and deform, which can be achieved by wrapping a braided structure with rubber or silicone material. Their flexibility allows for adjustment of the installation angle in narrow spaces. Rigid pipes refer to rigid pipes with a fixed shape, which can be made of stainless steel or plastic material. Their structural stability can prevent displacement caused by water flow impact.

[0040] Specifically, the water outlet pipe 8 can be either a flexible hose or a rigid pipe depending on the installation scenario. For example, when the water outlet device needs to pass through complex bends, the flexible hose can adapt to external space constraints through its own deformation, reducing assembly difficulty. During assembly, the flexible hose is connected to the adapter 3 via a flexible sleeve, while the rigid pipe is axially fixed through threads, snap-fit ​​structures, or plug-in connections.

[0041] This application further proposes a water outlet device, including a body with a water outlet support arm, a valve core cavity 1 on the body, a water outlet pipe 8 on the support arm, a valve core 1 assembly inside the valve core cavity 1, and the water outlet pipe 8 connected to the other end of the adapter 3. The communication port between the support arm and the valve core cavity 1 is arranged opposite to the opening of the channel.

[0042] This application further proposes that the connection port of the support arm and the valve core 1 cavity are arranged opposite to the opening of the channel. The opposite arrangement of the channel openings means that the outlet of the channel inside the valve core 1 cavity that passes through the base 5 and the valve seat 2 is on the same axis as the connection port of the support arm, so as to facilitate better connection of the water outlet pipe 8 to the other end of the adapter 3.

[0043] The valve core assembly is designed to be directly connected to the adapter 3 via the water outlet pipe, which prevents the water flowing out of the valve core assembly from directly contacting the faucet body or water outlet support arm of the water outlet device, thus avoiding water pollution.

[0044] The following describes the installation steps for the valve core 1 assembly:

[0045] First, place the valve seat 2 into the valve core 1 cavity through the upper opening of the valve core 1 cavity. Pass the water outlet pipe 8 through the channel of the water outlet support arm and connect one end to the other end of the adapter 3. Then, place the adapter 3 on the limiting groove 14 of the valve seat 2 so that one end of the adapter 3 is in a vertically upward state. Of course, this state can be adjusted by rotating the water outlet pipe 8. Then, extend the valve core 1 into the upper opening of the valve core 1 cavity and press it down so that the water outlet channel on the valve core 1 base 5 is close to one end of the adapter 3, so that one end of the adapter 3 is inserted into the water outlet channel. Finally, the valve core 1 is limited and fixed by the upper cover.

[0046] Because the design of the seal 4 reduces the requirements for installation accuracy; the gradually expanding design of the guide sealing surface 12 allows for a certain range of positional deviations, automatically corrects the alignment during the pressing process, facilitates installation and improves assembly efficiency; at the same time, it forms a multiple sealing effect.
