Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water pipe anti-corrosion protection, in particular to a water pipe protective sleeve cap. Background Art
[0002] A water pipe is a hose structure that can divert liquids. Taking a washing machine as an example, when the washing machine is installed, the water pipe will directly connect the water inlet and the water pipe outlet of the washing machine. The water inlet structure is generally the water pipe head mentioned in this application.
[0003] In existing washing machines and other structures, the water pipe head generally directly adopts a stainless steel water pipe structure, but this structure has the following problems:
[0004] 1) The naturally placed water pipe head will sink to the bottom of the water because of its metal material and higher density than water. If the bottom of the water is flat, there is a certain probability that the water delivery end face is parallel to the bottom of the water, so that if the water pipe head is used as the water inlet pipe, the water delivery end face cannot be filled with water or it is difficult to fill with water;
[0005] 2) The outer surface of the water inlet pipe head of the washing machine is worn for a long time, and due to long-term corrosion by corrosive liquids such as laundry detergent, the head is prone to rust.
[0006] Therefore, a water pipe protective cap is proposed to solve the above problems. Utility Model Content
[0007] In order to solve the problems raised in the above background technology, the utility model provides a water pipe protective cap, which has the advantages of reducing the risk of rusting of the water inlet end of the water pipe head and preventing water from failing to enter at a specific angle.
[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water pipe protective cap, comprising a protective cap, the protective cap is a hollow cylindrical structure, the inner surface of the protective cap is provided with a connecting surface that can be connected with the outer surface of the water pipe head, the top of the water pipe head is fixedly provided with a hexagonal positioning piece, the top of the hexagonal positioning piece is fixedly provided with a connecting bolt that can be connected to the water pipe, and the water inlet end of the protective cap has at least one radially arranged groove that passes through the hollow part of the protective cap.
[0009] The groove is designed to prevent the problem of difficulty or inability to enter water when the bottom surface of the protective cap is in direct parallel contact with the bottom surface of the water inlet.
[0010] It should be made clear that the presence of the grooves can not only prevent water from entering at a specific contact angle, but also achieve a certain degree of filtering effect, so that granular impurities with a diameter larger than the groove cross-section can be filtered out.
[0011] Furthermore, there are two grooves, which are arranged along the diameter of the water inlet end surface of the protective cap.
[0012] Furthermore, there are more than three grooves, which are evenly distributed along the circumference of the water inlet end surface of the protective cap, and all penetrate and connect to the hollow part of the protective cap.
[0013] The purpose of these two clauses is to state that there can be multiple grooves, but in general, two grooves are used as the standard, taking into account both increasing the water inlet volume and the minimum water inlet volume under special contact angles. If only one groove is used, the water inlet volume is too small, and using too many grooves is unnecessary and will affect the filtering effect.
[0014] Furthermore, the connection surface is a first threaded portion, and the outer surface of the water pipe head is provided with a second threaded portion that can be matched and connected with the first threaded portion.
[0015] Furthermore, the connection surface is an elastic buckle arranged on the inner surface of the protective sleeve cap, and the outer surface of the water pipe head is provided with a groove that can be matched and connected with the elastic buckle.
[0016] The purpose of these two clauses is to state that there is no limitation to one connection method, but in general, it is a threaded connection.
[0017] Furthermore, the inner surface depth of the protective cap is greater than the extension length of the outer surface of the water pipe head, so that the end of the water pipe head cannot be exposed from the protective cap.
[0018] The protective cap can only play a role when the end of the water pipe head cannot be exposed from the protective cap. This is the premise.
[0019] Furthermore, the protective cap is a ceramic protective cap.
[0020] Ceramics have anti-corrosion properties.
[0021] Furthermore, the cross section of the groove along its extending direction is rectangular.
[0022] Furthermore, the cross section of the groove along its extending direction is semicircular or trapezoidal.
[0023] The purpose of these two points is to illustrate that the design focus of the groove is to form a channel rather than a specific shape. As long as a channel can be formed, theoretically, it is feasible.
[0024] Furthermore, the water inlet end of the protective cap can also serve as a water outlet end.
[0025] It can be used not only for water inlet but also for water outlet, but generally speaking, it is more used for water inlet. After all, if it is for water outlet, the water hose will be twisted under the action of hydraulic force, which directly overcomes the problem of water outlet cup blocking.
[0026] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0027] 1. The utility model designs the groove so that the water inlet can still be formed at a special contact angle to continuously deliver water, thereby preventing the problem of difficulty or inability to enter water when the bottom surface of the protective cap is in direct parallel contact with the bottom surface of the water inlet.
[0028] 2. The utility model adopts the design of ceramic protective cap, so that the surface of the water inlet / outlet can be protected against corrosion. BRIEF DESCRIPTION OF THE DRAWINGS
