Description

Technical Field

[0001] The invention belongs to the field of water heating equipment, and in particular relates to an anti-bending shower hose. Background Art

[0002] In domestic water heating equipment, a section of flexible hose is generally used to connect the shower head to the outlet joint of the water heater or the outlet of the mixing valve. At present, there are generally two types of such flexible hoses. One is to have two metal or plastic threaded joints at both ends of the exposed rubber or silicone hose, and the other is to have a flexible sheath made of spiral steel skin wrapped around the outside of the rubber or silicone hose, and two threaded joints are provided at both ends of the pipe, and the port of the spiral steel skin sheath is embedded in the threaded joint. These two types of hoses have their own advantages and disadvantages: the former hose has low manufacturing cost and comfortable feel, but the rubber tube near its threaded joint is easy to bend excessively during use and block the water flow, and repeated excessive bending is also easy to cause fatigue fracture of the hose; the latter hose is protected by the spiral steel skin sleeve, and the rubber tube near its threaded joint will not bend excessively during use to block the water flow, but it has disadvantages such as poor feel and high manufacturing cost.

[0003] In order to solve the above-mentioned deficiencies of the hose used in the current shower head, a shower hose with good flexibility, comfortable hand feel, good bending resistance of the joints at both ends and low manufacturing cost is needed. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the hose used in the shower equipment on the market mentioned in the background technology cannot meet the technical problems of flexibility, bending resistance, good hand feeling and low manufacturing cost. The purpose of the present invention is to provide a hose with good flexibility, comfortable hand feeling, good bending resistance of the joints at both ends and low manufacturing cost.

[0005] The present invention is achieved through the following technical solutions:

[0006] A bending-resistant shower hose comprises a hose, an end joint, a water-permeable component, an elastic hoop, an intermediate sheath and an anchor support;

[0007] A pipe end throat with a reduced diameter is provided in the hose near the pipe end of the hose and a stepped pipe end flange is provided at the pipe end of the hose. The water-permeable components are divided into three groups and filled in the hose, two of which are located between the pipe end throat and the pipe end of the hose, and the other group is located in the middle of the hose and the water-permeable components of this group are limited in the middle of the hose by two elastic hoops sleeved on the outside of the hose;

[0008] The end connector is installed at the end of the hose and is used to connect with a shower head or a water supply faucet;

[0009] The middle section of the hose is embedded in the middle sheath and fixed to the external structure through anchoring.

[0010] Furthermore, the water-permeable assembly is composed of a plurality of hollow water-permeable balls, which are arranged along the length direction of the hose, and a plurality of through water-permeable holes are provided on the side walls of the water-permeable balls.

[0011] Furthermore, the end joint includes a threaded joint, a magnetic filter and a locking ring. The magnetic filter is arranged inside the threaded joint. The locking ring and the threaded joint are connected by threads and the hose and the threaded joint are connected together by means of the pipe end flange of the hose.

[0012] Furthermore, the intermediate sheath is composed of an open tube support outer sleeve with a semicircular cross section and a tube support inner sleeve embedded therein.

[0013] Furthermore, the anchor support is composed of an open anchor sleeve with a semicircular arc cross section and an anchor nail embedded therein, and the anchor nail can be fixed on the wall.

[0014] Furthermore, the water-permeable ball is made of metal or engineering plastic material.

[0015] Furthermore, the elastic hoop is made of high-elastic rubber or metal spring.

[0016] Compared with the prior art, the present invention has the following advantages: the structural design of the hose in the present invention embeds multiple groups of hard hollow water-permeable balls at both ends and the middle part, and due to the supporting, water-permeable and mutually displaceable characteristics of the hollow water-permeable balls, the hose can simultaneously obtain the characteristics of anti-bending and flexibility. The present invention has the advantages of simple structure, good flexibility, anti-bending and clogging, good feel in use, and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0027] A bending-resistant shower hose, comprising a hose 1, an end connector 2, a water-permeable component, an elastic hoop 4, an intermediate sheath 5 and an anchor support 6;

[0028] A pipe end throat 11 with a reduced diameter is provided in the hose 1 near the pipe end of the hose 1, and a stepped pipe end flange 12 is provided at the pipe end of the hose 1. The water-permeable components are divided into three groups and filled in the hose 1, two of which are located between the pipe end throat 11 and the pipe end of the hose 1, and the other group is located in the middle of the hose 1. The water-permeable components of this group are limited in the middle of the hose 1 by two elastic hoops 4 sleeved on the outside of the hose 1;

[0029] The end connector 2 is installed at the end of the hose 1 and is used to connect with the shower head 101 or the water supply tap 102;

[0030] The middle section of the hose 1 is embedded in the intermediate sheath 5 and fixed to the external structure through the anchor 6 .

[0031] In this embodiment, the water-permeable assembly is composed of a plurality of hollow water-permeable balls 3 , which are arranged along the length direction of the hose 1 , and a plurality of through water-permeable holes are provided on the side walls of the water-permeable balls 3 .

[0032] In this embodiment, the end connector 2 includes a threaded connector 21, a magnetic filter screen 22 and a locking ring 23. The magnetic filter screen 22 is arranged inside the threaded connector 21. The locking ring 23 and the threaded connector 21 are connected by threads and the hose 1 is connected to the threaded connector 21 by means of the pipe end flange 12 of the hose 1.

[0033] In this embodiment, the intermediate sheath 5 is composed of an open tube support outer sleeve 51 with a semicircular cross section and a tube support inner sleeve 52 embedded therein.

[0034] In this embodiment, the anchor support 6 is composed of an open anchor sleeve 61 with a semicircular arc cross section and an anchor nail 62 embedded therein, and the anchor nail 62 can be fixed on the wall 103.

[0035] In the structure of the above embodiment, the hose 1 is made of rubber, silicone and other materials, the elastic hoop 4 is made of high-elastic rubber or metal spring, the magnetic filter 22 is made of magnetic metal or polymer material, the anchor sleeve 61 is made of metal or plastic, the anchor nail 62 is made of metal or directly an expansion screw; the remaining parts are made of metal or engineering plastic materials.

[0036] The application method of the present invention is as follows:
