Improved split faucet

Technical Field

The utility model relates to a tap technical field, in particular to improved generation components of a whole that can function independently tap.

Background

The known water faucet comprises a valve body, a water inlet pipe and a water outlet pipe, wherein the water inlet pipe and the water outlet pipe are communicated with the valve body, and water flows into the valve body from the water inlet pipe, passes through a valve core in the valve body and then flows out from the water outlet pipe. The known faucet valve body and the valve core are generally integrally cast and formed by brass or zinc alloy, the production process requirement is high during casting, the machining process is complex, toxic heavy metal lead chemical components are contained in casting materials, the national standard requirement cannot be met, the environment is not protected, the human health is influenced, in addition, the known faucet valve body and the valve core are all made of multi-metal materials, the material cost is high, the corrosion prevention effect of a metal flow channel is not good, and the water quality and the taste are influenced after the faucet valve body and the valve core are used for a long time.

Referring to fig. 1, in order to solve the above technical problems, chinese patent No. 2016202953001 discloses an improved split faucet, including a zinc alloy faucet body 1 ' and a plastic inner valve core tube 2 ' disposed in the zinc alloy faucet body 1 ', the zinc alloy faucet body 1 ' has a hollow inner cavity, one side of the middle portion of the zinc alloy faucet body 1 ' is provided with a valve core mounting tube 11 ', the plastic inner valve core tube 2 ' is provided with a water inlet tube and a water outlet tube 23 ' along an axial direction, the water inlet tube includes a cold water inlet tube 21 ' and a hot water inlet tube 22 ', the bottom inner cavities of the cold water inlet tube and the hot water inlet tube are provided with a copper sleeve 24 ', and the inner wall of the copper sleeve is provided with copper hole teeth. The plastic inner valve core tube 2 'is internally provided with a water outlet valve seat 25' between the water inlet tube and the water outlet tube, the water outlet valve seat 25 'is provided with a water inlet through hole communicated with the cold water inlet tube 21', a hot water inlet tube 22 'and the valve core mounting tube and a water outlet through hole communicated with the water outlet tube, the plastic inner valve core tube 2' is inserted in the zinc alloy faucet body 1 ', the water outlet valve seat 25' of the plastic inner valve core tube 2 'is arranged corresponding to the valve core mounting tube 11' of the zinc alloy faucet body 1 ', and metal particles 3' are filled between the plastic inner valve core tube 2 'and the zinc alloy faucet body 1', and a plurality of metal particles are gathered to form a honeycomb metal anti-freezing protective layer. An axial positioning device capable of preventing the plastic inner valve core 2 ' pipe from making axial displacement and a radial positioning device capable of limiting the plastic inner valve core pipe from making radial rotation are further arranged between the plastic inner valve core pipe 2 ' and the zinc alloy faucet body 1 '. The axial positioning device comprises a metal axial limiting cover 41 ', the metal axial limiting cover 41' is spirally arranged at the opening at the lower end of the zinc alloy faucet body 1 ', a through hole is formed in the middle of the metal axial limiting cover 41', and a thread is arranged in the through hole. The plastic inner core pipe is positioned at the bottoms of the cold water inlet pipe and the hot water inlet pipe and is further provided with a positioning sleeve 5 'used for positioning the cold water inlet pipe and the hot water inlet pipe, positioning blocks 51' connected with the bottom of the zinc alloy faucet body are uniformly distributed on the outer side of the circumference of the positioning sleeve 5 ', the inner diameter of the metal axial limiting cover 41' is smaller than the outer diameter of the positioning sleeve 5 'at the bottom of the plastic inner valve core pipe 2' so as to prevent the plastic inner valve core pipe and metal particles 3 'from moving downwards, and the inner diameter of the upper part of the zinc alloy faucet body 1' is smaller than the outer diameter of the upper part of the plastic inner valve core pipe 2 'so as to form a limiting step capable of limiting the plastic inner valve core pipe 2' and the metal particles 3 from moving upwards. The radial positioning device is: the outer side wall of the upper part of the plastic inner valve core tube 2 'is uniformly provided with clamping grooves 29', and the upper part of the zinc alloy faucet body 1 corresponding to the positions of the clamping grooves 29 'is respectively provided with a limiting bulge which can extend into the clamping grooves 29'. According to the anti-freezing metal tap, the metal tap body shell and the plastic inner valve core pipe are filled with the metal particle anti-freezing protection layer, so that the plastic inner valve core pipe can be prevented from being frozen and cracked under the influence of cold air or a cold water source; make this metal tap body and plastics interior case pipe between the installation back no space, have the clearance between each metal particle in the metal particle anti-freezing protection layer and form the honeycomb and prevent frostbite protective layer, but the moist air or the moisture of this clearance adsorbability entering avoids moist air or moisture to get into metal tap body inner wall, causes the phenomenon of metal tap body oxidation, corruption.

When the metal particle anti-freezing protection layer is installed, the positioning blocks 51 'are set on the positioning cover 5' of the water inlet pipe, each metal particle is filled into the space between the zinc alloy faucet body 1 'and the plastic inner valve core pipe 2' from the filling groove between the adjacent positioning blocks 51 ', and finally the metal particle is sealed in the zinc alloy faucet body 1' and the plastic inner valve core pipe 2 'through the metal axial limiting cover 41', as shown in fig. 1, the installation mode has the following defects:

1. in the installation mode, metal particles are sealed in the zinc alloy faucet body 1 'and the plastic inner valve core pipe 2' through the metal axial limiting cover 41 ', and when the metal axial limiting cover 41' is loosened or falls off in the use process, the metal particles can be downwards leaked from a filling groove between adjacent positioning blocks 51 ', so that the use effect is influenced, and the interference on the secondary locking of the metal axial limiting cover 41' is caused;

2. when filling metal particles, each metal particle needs to fill from the downside of the tap body upwards, the resistance is large during filling, and the phenomenon that the metal particles between the two are not filled is easy to appear, thereby influencing the use effect and the installation stability.

3. The existing water outlet pipe is welded on a faucet shell, the process is complex, and the water outlet pipe is not environment-friendly, so that the water outlet pipe is directly locked outside the shell on the inner core by using a bolt in the prior art, but the water outlet pipe cannot be positioned when being locked, the water outlet pipe can be locked only by manual positioning during operation, and the operation is difficult.

4. The lower end of the chassis of the existing plastic inner valve core pipe is generally provided with a mounting seat for connecting an external vegetable basin, and the part of the connecting mounting seat with threads is generally exposed at the lower end of the faucet shell, so that the lower end of the faucet is quite unattractive, therefore, in the prior art, the part with threads and the mounting seat are generally electroplated into the same color at the same time, and the ornamental effect after the part with threads at the lower end of the chassis is connected with the mounting seat is improved, but the production cost of the faucet is improved by the method.
