Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of faucets, and particularly relates to an intelligent universal temperature-adjusting faucet valve assembly. BACKGROUND

[0002] Currently, the connection between the electromagnetic valve seat and the temperature-adjusting valve chamber usually adopts multiple fasteners for fixation, the fasteners being screws or bolts, and the installation angle between the valve seat and the temperature-adjusting valve chamber is usually fixed, that is, the position of the water outlet pipe on the valve seat is fixed. In different faucet individuals, the directions of the water inlet and the water outlet are on the same side in some cases, and are not on the same side in other cases, which requires matching of different valve seats and cannot be universal.

[0003] In addition, in order to prevent the cold and hot water paths from being connected in series, a check valve is usually installed at the cold and hot water inlet end. Due to the integrated design of the double water paths, the waterway space is limited and the traditional check valve cannot be installed. Moreover, the traditional check valve has high cost, occupies large space, and has low installation efficiency, and therefore it is urgent to develop an intelligent universal temperature-adjusting faucet valve assembly which occupies small space, has low cost, and is convenient to install.

[0004] In addition, the warm water outlet of the temperature-adjusting valve core in the prior art is a circular hole. Referring to patent No. 200910126100.8, since the temperature-adjusting valve core needs to be rotated during temperature adjustment, an included angle is formed between the warm water outlet and the water inlet between the electromagnetic valve seat after temperature adjustment, which causes the warm water outlet to be eccentric and makes the water inlet in the valve seat impact the electromagnetic valve diaphragm on a single side. In this way, the electromagnetic valve is unbalanced in stress, and the diaphragm is prone to damage over a long period of time.

[0005] In addition, the temperature-adjusting valve chamber in the prior art is designed with a blind hole for insertion of the temperature-adjusting valve core, and the temperature-adjusting valve core is designed as a hollow with one end open, as in patent No. 200910126100.8. When the electromagnetic valve is in a closed state (i.e., no water is discharged), the water pressure in the valve chamber is too high, which pushes the valve core outward, and the valve core fixing member and the valve core are stuck, thereby causing the valve core to feel heavy. When the electromagnetic valve is in an open state (i.e., water is discharged), the water pressure is discharged through the valve chamber outlet hole, the water pressure in the valve chamber is reduced, and the valve core is in a low-pressure state, so the valve core feels light, causing uneven temperature adjustment.

[0027] The present application will be further described below in combination with examples.

[0028] Examples

[0029] As Figures 1-7The illustrated intelligent universal temperature-adjusting faucet valve assembly includes a temperature-adjusting part, a valve body connecting seat 1, an electromagnetic valve 2 and a valve seat 3. The structure of the electromagnetic valve 2 and the valve seat 3 and the principle of the temperature-adjusting part are all prior art and will not be described in detail. In this embodiment, the electromagnetic valve 2, the valve seat 3 and the temperature-adjusting part are fixed on the valve body connecting seat 1 by means of a screw rod 4. In order to enable the installation to be able to change direction and to facilitate the installation of the water outlet pipe 5 on the valve seat 3 in a narrow space, the fastener mounting holes 6 of the four parts of the electromagnetic valve 2, the valve seat 3, the temperature-adjusting part and the valve body connecting seat 1 are distributed in the form of a regular polygon of equal size, so that the water outlet on the valve seat 3 can be selectively installed. In this embodiment, the fastener mounting holes 6 are four in number and are distributed in the form of a square, so that the water outlet pipe can be installed in four directions which can be selected. In order to improve the connection strength, the valve body connecting seat in this embodiment is made of metal material.

[0030] The temperature-adjusting part described in this embodiment includes a temperature-adjusting valve cabin 7 and a temperature-adjusting valve core 8. In this embodiment, the upper surface of the valve body connecting seat 1 is provided with cold and hot water outlets and four connecting screw holes. In this embodiment, the screw rod 4 penetrates the electromagnetic valve 2, the valve seat 3 and the temperature-adjusting valve cabin 7 in sequence and is connected with the valve body connecting seat 1. The temperature-adjusting valve cabin 7 is provided with a space for inserting the temperature-adjusting valve core 8. The space has a stepped structure, which can prevent the sealing ring from being cut when it is sealed between the temperature-adjusting valve core and the temperature-adjusting valve cabin. The temperature-adjusting valve core 8 is placed in the space. In this embodiment, the temperature-adjusting valve cabin is made of plastic material, which has the advantages of stable size, good sealing, low cost, high cost performance and light hand feeling. The temperature-adjusting valve cabin 7 is provided with two water inlets and one water outlet. The temperature-adjusting valve core 8 is also provided with two water inlets and one water outlet. The valve body connecting seat 1 is provided with a hot water connecting end 11 and a cold water connecting end 12. The valve body connecting seat 1 is fixedly connected with the temperature-adjusting valve cabin 7. In order to prevent the temperature-adjusting part from being waterlogged, this embodiment is provided with a gravity ball 9 and a valve cover 10 between the valve body connecting seat 1 and the temperature-adjusting valve cabin 7. The valve cover 10 is provided with a gap for water flow. When the gravity ball 9 comes into contact with the valve cover 10, water flows through the gap. The gravity ball 9 and the valve body connecting seat 1 are provided with a water stop. The valve cover 10 is arranged between the gravity ball 9 and the water inlet of the temperature-adjusting valve cabin 7. When the cold and hot water inlets of the valve body connecting seat 1 stop supplying water, the gravity ball 9 loses the influence of water pressure and is sealed with the water stop due to the influence of gravity and / or the influence of reverse pressure, thereby preventing waterlogging. In this embodiment, the two water inlets of the valve body connecting seat 1 are each provided with a gravity ball 9, a valve cover 10 and a water stop 14. The water inlets of the valve body connecting seat 1 are provided with a counterbore portion 13. The water stop 14, the gravity ball 9 and the valve cover 10 are arranged in the counterbore portion 13 and can move up and down in the counterbore portion.

[0031] In order to enable water flow from the valve cover 10 into the temperature regulating valve cabin 7 when the gravity ball 9 is in contact with the valve cover 10, the valve cover 10 has a through hole in the present embodiment, and the side wall of the valve cover 10 is provided with a water path in communication with the through hole. Specifically, the side of the valve cover 10 in contact with the gravity ball 9 is provided with a plurality of protrusions 101 protruding from the surface, and the adjacent two protrusions 101 have a gap therebetween and form a water path in communication with the through hole. When the water inlet end of the valve body connecting seat 1 is filled with water, the gravity ball 9 is impacted by the upward water pressure and is in contact with the valve cover 10. At this time, the water flow flows from the periphery of the gravity ball 9 and enters the through hole from the gap between the protrusions 101 of the valve cover 10, thereby entering the temperature regulating valve cabin 7. This design not only avoids the use of a complex structure of a one-way valve, but also avoids the use of a spring. The design can reduce the product size and reduce the number of parts to save costs.

[0032] The temperature regulating valve core 8 has a cold water inlet 87, a hot water inlet 86 and a warm water outlet 81. In order to prevent damage caused by uneven impact of the diaphragm of the electromagnetic valve 2, the warm water outlet 81 of the temperature regulating valve core 8 is designed in an 8-shaped structure or a long slot structure in the present embodiment.

[0033] In order to limit the rotation angle of the valve core, a positioning column 88 is arranged on the valve core, and a notch 71 is arranged on the temperature regulating valve cabin to limit the movement range of the positioning column 88 on the valve core. After the valve core and the temperature regulating valve cabin are installed, the positioning column is placed in the notch of the temperature regulating valve cabin, thereby limiting the rotation angle of the valve core when the valve core is rotated, thereby facilitating the adjustment of water temperature.

[0034] In order to prevent uneven hand feeling during temperature regulation, a through hole is arranged in the temperature regulating valve cabin 7 for the temperature regulating valve core 8 to pass through. The temperature regulating valve core 8 is arranged through the temperature regulating valve cabin 7, and a sealing ring 82 is arranged between the outer side of the two ends of the temperature regulating valve core 8 and the inner wall of the temperature regulating valve cabin 7. The surface of the temperature regulating valve core 8 is provided with a groove for the sealing ring 82 to be clamped into. The part of the temperature regulating valve core 8 passing through the temperature regulating valve cabin 7 is provided with a limiting piece 83 for preventing the axial displacement of the temperature regulating valve core 8. The limiting piece 83 is a clamping spring, and the corresponding temperature regulating valve core 8 is provided with a clamping groove for the clamping spring to be clamped into.

[0035] Since the temperature regulating valve cabin 7 is a through design, a plug 84 is connected to one end of the temperature regulating valve core 8, and the other end is connected to a temperature regulating handle 85. The temperature regulating handle 85 is a prior art and will not be described in detail here.

[0036] The basic principles, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Simple changes and replacements made by ordinary skilled persons in the art without departing from the spirit and scope of the present application are within the protection scope of the present application.
