Detailed Description
The invention provides an anti-scalding faucet, which is further described in detail below with reference to the accompanying drawings and examples in order to make the purposes, technical schemes and effects of the invention clearer and more definite. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Herein, front refers to a direction away from the wall, and rear refers to a direction toward the wall.
Referring to fig. 1-4, an anti-scalding faucet comprises a shell 1 and a core tube 2 inserted in the shell; the two ends of the core tube are respectively provided with a cold water inlet 21 and a hot water inlet (not shown in the figure, the cold water inlet and the hot water inlet are symmetrically arranged), the middle part of the core tube 2 is provided with an upper water outlet 22 for supplying water to the shower head and a lower water outlet (not shown in the figure, the upper water outlet and the lower water outlet are on the same vertical line), correspondingly, the two ends of the shell are provided with a cold water connection port 11 and a hot water connection port 12, and the middle part of the shell is provided with an upper connection port 13 and a lower connection port 14; one end of the core tube 2, which is close to the cold water inlet 21, is provided with a flow valve core 3, the flow valve core is connected with a flow hand wheel 31, the other end of the core tube is provided with a gear valve core 4, and the gear valve core is connected with a gear hand wheel 41; the core pipe is respectively communicated with an external cold water pipeline and a hot water pipeline through two connecting pipes 5; a gap is arranged between the inner surface of the shell 1 and the outer surface of the core tube 2.
Because the gap is arranged between the shell 1 and the core tube 2, when hot water flows through the core tube 2, heat is difficult to transfer to the shell, so that the shell can be prevented from being heated by the hot water, and a user is prevented from being scalded by the shell.
Specifically, as shown in fig. 1 and 2, the outer diameter of the core tube 2 is smaller than the inner diameter of the shell 1, a plurality of annular protrusions 23 are arranged on the outer wall of the core tube along the length direction, and the outer diameter of the annular protrusions is adapted to the inner diameter of the shell. The core tube is supported in the shell through the annular bulge to form a heat-insulating gap.
Further, the pipe diameter of a section of pipe body 24 positioned between the hot water inlet and the upper water outlet/lower water outlet on the core pipe is smaller than that of other parts. Since hot water mainly flows through the pipe body 24 of the section, reducing the pipe diameter of the section can increase the gap between the pipe body and the shell, and the heat insulation effect is improved.
In order to realize the rapid and accurate alignment of the water inlet and the water outlet on the core tube and the corresponding connectors on the shell, a positioning protrusion (not shown in the figure) extending along the length direction is arranged on the inner wall of the shell 1, and a corresponding positioning clamping groove 231 is formed on the annular protrusion 23 of the core tube 2. When the positioning clamp groove is aligned with the positioning protrusion during assembly, the core pipe is inserted into the shell, and the core pipe cannot rotate in the shell, so that quick and accurate alignment is realized.
In the embodiment, the core tube 2 is made of high temperature resistant nylon (namely PPA plastic commonly known as PPA plastic); the housing 1 is made of copper alloy. The high-temperature resistant nylon has high-temperature resistant performance, can not be easily deformed due to the high temperature of hot water, has low heat conductivity, can reduce the heat transferred out, and the copper alloy has larger density and specific heat capacity, so that the heat required by heating is larger, the heating is not easy, and the anti-scalding effect is greatly improved by the paired use of the two materials.
Specifically, as shown in fig. 1 and 3, the connecting pipe 5 is a curved leg, and when the deviation of the hole pitch of the water outlet position reserved on the wall affects the installation, the influence can be counteracted by adjusting the angle of the curved leg.
Further, a filter screen 51 is disposed between the connecting pipe 5 and the core pipe 2 to prevent impurities in water from flowing into the faucet.
Further, a check valve 52 is provided between the filter screen 51 and the core tube 2 to prevent water in the faucet from flowing back.
In this embodiment, as shown in fig. 3, the cold water inlet and the hot water inlet of the core tube 2 are respectively inserted with a communication head 53, the rear end of the communication head 53 (the direction away from the core tube later) passes out of the cold water connection port 11 or the hot water connection port 12 and is connected with a communication nut 54, and the rear end of the communication nut 54 is connected with the connection pipe 5; the inside of the communication head 53 is provided with a clamp spring 55, a check valve 52 and a filter screen 51 in sequence from front to back, and O-shaped sealing rings 56 are arranged at the joint of the communication head 53 and the core pipe 2 and the joint of the communication head 53 and the communication nut 54; a sealing gasket 57 and a decorative cup 58 are arranged between the communication nut 54 and the connecting pipe 5, and the decorative cup 58 is fixed on the connecting pipe 5 through a special-shaped ring 59.
Specifically, as shown in fig. 1 and 4, the upper connecting port 13 and the lower connecting port 14 are respectively connected with the connecting head 6 through threads; each connector 6 comprises a plug portion 61 extending into the upper water outlet 22 or the lower water outlet, a first threaded portion 62 connected to the upper connector 13 or the lower connector 14, and a second threaded portion 63 for connection to a shower or bath faucet; the diameter of the inserting portion 61 is smaller than that of the first threaded portion 62, the diameter of the first threaded portion 62 is smaller than that of the second threaded portion 63, the inserting portion 61 is sleeved with a first sealing ring 90, and the first threaded portion 62 is sleeved with a second sealing ring 91. After the core tube 2 is inserted into the shell 1, the connector 6 is screwed in, the axial position of the core tube is limited, and the assembly is simple and quick.
Preferably, as seen in fig. 1, wear rings 7 are provided between the flow spool 3 and the flow hand wheel 31, and between the gear spool 4 and the gear hand wheel 41, to increase service life.
It will be understood that equivalents and modifications will occur to those skilled in the art in light of the present invention and their spirit, and all such modifications and substitutions are intended to be included within the scope of the present invention as defined in the following claims.
