Example Embodiment

[0040] Preferred Embodiment One

[0041] Please check Figure 1 to Figure 5 , An anti-backflow mechanism used in the field of bathing, it includes a base 100 and an elastic seal 200.

[0042] The base 100 includes a sleeve 110, a fixing seat 120 and a plurality of spokes 130. The inner hole of the sleeve 110 is formed as a water channel 140. In this embodiment, the inner hole is a stepped hole, and the stepped surface 141 of the stepped hole may be a flat surface or an inclined surface. The fixing base 120 is located in the waterway 140 and is fixed in the waterway 140 by a plurality of spokes 130. The spokes 130 are in an annular array, and a passage is formed between every two spokes 130 spaced apart. A through hole 121 is provided in the fixing base 120. Preferably, an annular groove 111 is recessed outside the sleeve 110, and an O-ring 112 is connected in the annular groove 111.

[0043] The elastic sealing member 200 is integrally formed and has an elastic sealing sheet 210...

Example Embodiment

[0047] Preferred embodiment two

[0048] It differs from the preferred embodiment one in that: please refer to Image 6 , The outer periphery of the elastic sealing sheet 210 is bent toward the back.

Example Embodiment

[0049] Preferred Embodiment Three

[0050] It differs from the preferred embodiment one in that: please refer to Figure 7 The elastic sealing sheet 210 includes a basic section 212, an inclined section 213 extending backward and outward from the periphery of the basic section 212, and a gripping section 214 extending from the inclined section forward and outward. The inclined section 213 and The grasping section 214 cooperates to form a V-shaped section, and the opening of the V-shaped section faces the positive direction.

Abstract

The invention discloses a backflow preventing mechanism applied in the field of bath. The backflow preventing mechanism comprises a base body and an elastic sealing member. The base body comprises a water path, a fixed seat and at least one spoke, wherein the fixed seat is positioned in the water path; the spoke is used for fixedly connecting the fixed seat with the water path; and channels are formed among the spokes. The elastic sealing member comprises an elastic sealing fin and a fixed head, wherein the fixed head is arranged on the front side of the elastic sealing fin; the fixed head is fixedly connected with the fixed seat; the elastic sealing fin is adaptive to the water path; when the water in the water path flows downstream, the elastic sealing fin is subjected to the downstream impact action to open the channels; and when the water in the water path flows upstream, the elastic sealing fin is subjected to the upstream impact action to seal the channels. The backflow preventing mechanism has the advantages of applicability to shower heads or faucets in the field of bath, high practicability, few parts and cost reduction.

Description

technical field [0001] The invention relates to an anti-backflow mechanism used in the field of bathing. Background technique [0002] The existing anti-backflow mechanism, such as ZL200720008772.5 disclosed in the Chinese patent database. The anti-backflow mechanism includes a base body, a spring and a seal. A water channel is formed inside the base. The seal is connected within the water circuit by a spring. When the waterway flows downstream, the water pressure is acting on the seal, compressing the spring and making the waterway conduction; when the waterway flows backward, the water pressure reacts on the seal, and the spring force acts on the seal, so that the seal seals the waterway . The existing anti-backflow mechanism has the following disadvantages: 1. There are many parts, high cost, and inconvenient assembly; 2. It takes up a lot of space and is not suitable for water outlet terminals in the bathing field, such as showers or faucets, and is not practical. ...
