Description

Technical Field

[0001] The utility model relates to the technical field of valve cores, in particular to a valve core and a water outlet device which can be directly connected to a water pipe. Background Art

[0002] Most of the existing valve cores on the market require a seal between the end face of the valve core and the faucet body, or a seal between the outer circumference of the valve core and the faucet body, and then connected to the water inlet and outlet pipes. The end face seal is because the hose is connected to the body instead of directly connected to the valve core, which requires sealing to be set on the lower end face of the valve core and the outer circumference of the valve core for sealing. This will make the structure of the valve core more complicated, increase the production and installation costs, and on the other hand, the seal is easily squeezed and damaged during the installation process, resulting in water leakage.

DETAILED DESCRIPTION

[0026] Combination Figures 1 to 7 As shown, this embodiment provides a water outlet device, including a valve core that can be directly connected to a water pipe. The valve core that can be directly connected to a water pipe includes a valve body 1, a water control component 3 is arranged in the valve body 1, the water control component 3 includes a water mixing device 32 and at least one water inlet connected to the water mixing device 3, and the valve body 1 is provided with at least one water inlet installation hole 11 that is connected to the water inlet and is suitable for directly installing a water inlet pipe.

[0027] Combination Figure 1 As shown, in this embodiment, the water control component 3 includes an operating device 31 and a water mixing device 32, and the operating device 31 is used to control the water mixing device 32 to mix water. Of course, in other embodiments, when there is only one water inlet channel, the water mixing device 32 can be replaced by an existing opening and closing component. A valve shell 2 is provided on the valve body 1, and the valve shell 2 is connected to the valve body 1 to fix the water control component 3. The connection position of the valve body 1 and the valve shell 2 can be set at any different axial position; the connection between the valve body 1 and the valve shell 2 can also be achieved in different ways, such as snap-fit, welding, etc., and preferably a snap-fit ​​connection is used to facilitate disassembly.

[0028] In one embodiment, the operating device 31 includes components such as a rocker 311 and a rocker seat 312, and the water mixing device 32 includes a moving piece 322 and a static piece 321. The static piece 321 is fixed on the valve body 1, and a seal 323 is provided between the static piece 321 and the valve body 1 for sealing; the rocker 311 is connected to the moving piece 322 to control the movement of the moving piece 322 on the static piece 321, thereby realizing opening and closing control and water mixing control. A positioning platform 16 suitable for fixing the static piece is provided in the valve body 1. A water inlet and a water outlet are provided on the valve body 1, and the water inlet and the water outlet are connected to the water inlet and outlet on the static piece 321. In this embodiment, the static piece 321 and the moving piece 322 can be made of ceramic pieces. It should be noted that the water control component 3 is not limited to the structure mentioned above.

[0029] In this embodiment, the water inlet mounting hole 11 can be arranged at the bottom of the valve body 1 and communicated with the water inlet, so as to be used to guide the water of the water inlet pipe into the water inlet. The water inlet mounting hole 11 can be provided with one, two, or even more; the water inlet mounting hole 11 extends downwardly to have a circular hole section arranged along the axis, which is used to install the water inlet pipe, and the circular hole section is provided to be sealed and connected with the water inlet hose through a sealing ring. In another embodiment, the bottom of the valve body 1 is also provided with a water outlet mounting hole 12 for connecting with the water outlet, so that the water outlet pipe can be directly inserted into the water outlet mounting hole 12. The side of the water inlet pipe is provided with a sealing ring that is sealed and connected with the water inlet mounting hole 11. When a water outlet pipe is provided, a sealing ring is also provided on the side of the water outlet pipe for connection to ensure the sealing of the connection. Since the water inlet pipe and the water outlet pipe are directly connected and fixed on the valve body 1, there will be no risk of water leakage between the valve body 1 and the main body of the water outlet device. Similarly, since the water outlet pipe is directly installed on the valve body 1, there will be no risk of water leakage between the valve body 1 and the inner wall of the main body. Therefore, there is no need to set seals at the above two positions.

[0030] Combination Figures 2 to 5 As shown, in one embodiment, a limiting structure 13 is provided on the outside of the valve body 1, and the limiting structure 13 is configured to limit the rotation of the valve body 1 in the water outlet device when the valve core is installed in the water outlet device. Specifically, the limiting structure 13 is a limiting spline or a limiting block or a limiting rib or other structure that can be used to limit the rotation of the valve body 1. The limiting structure 13 provided on the outside of the valve body 1 can cooperate with the limiting structure 13 provided in the valve core installation groove of the water outlet device to prevent the valve body 1 from rotating. The height of the limiting structure 13 here is set between 0.5mm-3.5mm. Further, an axis positioning structure 14 is provided on the outside of the valve body 1 to limit the axial movement of the valve body 1 in the water outlet device when the valve core is installed in the water outlet device, and the axis positioning structure can be a positioning step provided on the outer peripheral side of the valve body 1. By providing the axis positioning structure to cooperate with the limiting structure 13, the valve core will not rotate or shake up and down when it is fixed in the water outlet device. Through the arrangement of this structure, after the bottom end connection between the valve core and the water outlet device is cancelled, the stability of the valve core in the water outlet device is ensured.

[0031] Combination Figures 1 to 6 As shown, as a preferred arrangement, in one embodiment, a boss 15 with an opening is provided at the lower portion of the valve body 1, and the opening direction of the boss 15 is perpendicular to the central axis direction of the valve body 1. Here, the boss 15 with an opening can be installed with a fixing plate for fixing the water inlet pipe and the water outlet pipe, and can also be used to facilitate positioning and guiding with the structure of the water outlet device. Of course, in other embodiments, the boss 15 may not be provided.

[0032] The water inlet pipe and the water outlet pipe described in this embodiment can adopt an existing hose assembly, and the end of the hose assembly can be provided with a sealing ring for maintaining a seal with the water inlet installation hole 11 or the water outlet installation hole 12.

[0033] It should be noted that the water outlet device may be a faucet, shower device or other water outlet functional equipment.

[0034] Through the arrangement of this embodiment, unlike the valve core of traditional design, no seal is required between the end face of the valve core and the faucet body, and no seal is required between the outer circumferential surface of the valve core and the faucet body. The structure also has the advantages of simple structure and fewer parts.

[0035] It should be understood that the above are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.

[0036] The above description of the drawings used in the implementation manner only shows certain embodiments of the utility model and should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without paying creative work.
