Description

TECHNICAL FIELD

[0001] The utility model relates to a shower technical field, especially point to a kind of face cover structure of shower. BACKGROUND

[0002] After long time use, the water outlet hole on the water outlet face cover of shower is easy to be blocked by scale or impurities, leading to problems such as oblique emission, insufficient jetting force of shower water, affecting shower experience.

[0003] The current solution is to set the water outlet nozzle to flexible material, and to form by pouring glue on the face cover framework. When cleaning, use the flexible characteristics of the water outlet nozzle, rub the water outlet nozzle by hand or use a dedicated cleaning brush to insert the water outlet nozzle for brushing, which can discharge the blockage, but the cleaning efficiency is very low, and some impurities with larger volume are not easy to discharge. In addition, the processing cost of pouring glue on the flexible water outlet nozzle on the face cover framework is also very high. UTILITY MODEL CONTENT

[0006] A face cover structure of shower, comprising a face cover framework and a flexible face cover; the face cover framework is provided with a plurality of mounting holes; the mounting holes are sequentially provided with a water sealing surface, a anti-drop surface and a mounting port in the axial direction; the caliber of the anti-drop surface gradually decreases from the water sealing surface to the mounting port; the flexible face cover is provided with a mounting portion corresponding to the mounting hole; the mounting portion is embedded in the mounting hole, and the peripheral surface thereof comprises a first straight surface in interference fit with the water sealing surface and a first inclined surface in interference fit with the anti-drop surface; the mounting portion is provided with a water passing cavity and at least one water outlet hole communicating with the water passing cavity; the inner wall of the water passing cavity comprises a second straight surface and a second inclined surface corresponding to the first inclined surface.

[0007] The caliber of the second inclined surface gradually decreases from the second straight surface to the water outlet hole.

[0008] The caliber of the mounting port gradually decreases from the outer side surface of the face cover framework to the anti-drop surface.

[0024] In order to further explain the technical scheme of the utility model, the utility model will be described in detail below through specific embodiments.

[0025] Reference Figures 1-5 As shown in the utility model discloses a shower's face cover structure, including face cover framework 1 and flexible face cover 2,

[0026] Face cover framework 1 is provided with a plurality of mounting holes 11, the axial direction of mounting hole 11 is sequentially provided with water sealing surface 111, anti-drop surface 112 and installation mouth 113, the caliber of anti-drop surface 112 gradually reduces from water sealing surface 111 to installation mouth 113 direction,

[0027] Flexible face cover 2 is provided with the installation portion 21 corresponding with mounting hole 11 one by one, and the peripheral surface of installation portion 21 is embedded in mounting hole 11, and the peripheral surface includes the first straight surface 211 of interference fit with water sealing surface 111 and the first inclined surface 212 of interference fit with anti-drop surface 112, and the water passing cavity 213 is arranged in installation portion 21, and at least one water outlet hole 214 is communicated with water passing cavity 213, and the inner wall of water passing cavity 213 includes the second straight surface 2131 and the second inclined surface 2132 corresponding to the first inclined surface 212, and specifically, the first inclined surface 212 is parallel with the second inclined surface 2132 or the extension line intersects.

[0028] Through the above scheme, when water flows, the water pressure is applied to the inner wall of water passing cavity 213 after water flow passes through water passing cavity 213, so that the outer wall of the corresponding installation portion 21 of water passing cavity 213 can be tightly fitted on water sealing surface 111 and anti-drop surface 112 of mounting hole 11, to prevent flexible face cover 2 from being separated from face cover framework 1, and improve the structural stability after installation, and meanwhile, by setting water sealing surface 111, water sealing surface 111 and the first straight surface 211 of installation portion 21 are interference fitted, which can prevent water flow from leaking out from the gap between mounting hole 11 and installation portion 21 when water flows, and further avoid the risk of causing separation due to the inward pressure applied to the outer wall of installation portion 21, the corresponding structure of the utility model can prevent flexible face cover 2 from being separated from face cover framework 1 when water flows, but flexible face cover 2 can be easily removed when not flowing, which facilitates users to clean flexible face cover 2 in the way of tool brushing, high-pressure flushing and the like, and improves the descaling efficiency.

[0029] The specific embodiments of the utility model are shown below.

[0030] The material of the above-mentioned flexible face cover 2 is the same as or similar to the material of the water outlet nozzle in the prior art, and has certain flexibility and elasticity.

[0031] The caliber of the above-mentioned second inclined surface 2132 gradually reduces from the second straight surface 2131 to the direction of water outlet hole 214.

[0032] The diameter of the mounting hole 113 gradually decreases from the outer side of the cover skeleton 1 to the direction of the anti-disengagement surface 112, that is, the mounting hole 113 has a gradually opened trend on the outer side of the cover skeleton 1, so that the upper end of the mounting portion 21 is inserted into the mounting hole 11. In the embodiment, the mounting hole 113 is in non-interference fit with the root of the mounting portion 21, and the flexible cover 2 is more easily removed without water.

[0033] The top surface of the second straight surface 2131 is not higher than the top surface of the water sealing surface 111, that is, the mounting portion 21 does not protrude from the inner side of the mounting hole 11, so that the pressure of the water flow in the shower on the outer wall of the mounting portion 21 is avoided, and the risk of water leakage and deformation of the mounting portion 21 inward to cause the mounting portion 21 to disengage from the mounting hole 11 is further prevented.

[0034] The peripheral surface of the cover skeleton 1 is provided with the anti-disengagement flange 12, and the peripheral surface of the flexible cover 2 is provided with the hook 22 which is buckled on the anti-disengagement flange 12, so that the flexible cover 2 is further prevented from disengaging, especially the loosening of the peripheral position.
