Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of faucet valve core, specifically relates to an improved two-in two-out valve core. BACKGROUND

[0002] In the continuous innovation of faucet technology, the valve core and faucet design are constantly improved to meet the diversified needs. At present, the faucet valve core is divided into water mixing valve core, water distribution valve core and multi-waterway valve core according to the function. For example, the patent number CN201210101026.6 uses a lever to realize multiple functions, but when the waterway is closed, the dynamic piece and the fixed piece bear high water pressure, and the sealing is easy to leak, which affects the use and life of the product. In the field of induction faucets, there are also many problems. After the electromagnetic valve switch of some products is damaged, it may not be able to induce water or flow water, increasing the use cost. Moreover, the intelligent faucet lacks intelligent integration, the operation is complicated, and the humanization degree is low. For example, the intelligent kitchen faucet, the intelligent control and temperature adjustment are not convenient. More importantly, the existing induction faucet has serious safety hazards, and the induction water is easy to scald. When the user reaches out to the induction area without any precautions, if the hot water flows out, it is easy to cause scalding accidents. For example, when the kitchen is busy, the induction water is triggered inadvertently, and if the water temperature is too high and cannot be adjusted in time, the risk of scalding increases.

[0003] Later, the patent document CN218543267U brings a new breakthrough. The double-waterway valve core has the rotation and sliding of the dynamic valve piece, realizing the functions of water mixing, water distribution and manual water closing. In the closed state of the waterway, the sealing ring between the dynamic valve piece and the fixed valve piece effectively avoids bearing high water pressure, significantly improving the service life of the valve core. The pull-out faucet can still be used as a normal faucet after the electric control switch is damaged, and it also has the function of automatic induction of water, and the overall structure design is more compact and reasonable.

[0004] However, the valve core with such a structure still has limitations in preventing full hot water scalding. When the electric control switch or control module fails, such as misjudgment of the induction part, loss of control of the electric control switch, the hot water passage may continue to be conducted, causing the user to be scalded by touching the full hot water. Moreover, the sliding and rotating actions of the dynamic valve piece may not be accurately coordinated when switching between manual and induction modes or operating in induction mode, making it difficult to control the proportion of hot water and increasing the risk of scalding. In addition, the overall structure of the faucet lacks a special anti-scald physical structure or safety protection device, and once the water temperature adjustment or water flow control is abnormal, it cannot automatically prevent the full hot water from flowing out.

[0005] In summary, although the faucet technology is constantly developing, the problem of easy scalding when the water is induced has not been properly solved in the existing technology, and further research and improvement are needed to ensure the safety and experience of users.

[0045] In Example 1, referring to Figures 1 to 6 As shown, the valve shell 1 is internally formed with a valve core cavity 1e, and the bottom thereof is provided with a cold water inlet 1a, a hot water inlet 1b, a first water outlet 1c, and a second water outlet 1d. The static valve plate 2a is provided with a cold water water passage 2a1, a hot water water passage 2a2, a first water passage 2a3, and a second water passage 2a4 corresponding to each water inlet.

When the moving valve plate 2b is switched to the first state, the mixed water outlet end 2b3 is always in a misaligned state with the second water passing hole 2a4, and the rotation of the moving valve plate 2b can make the mixed water inlet end 2b2 rotate to cover the cold water passing hole 2a1 and the hot water passing hole 2a2 to adjust the mixing ratio of cold and hot water flowing into the mixing channel 2b1, and the mixed water inlet end 2b2 can be in communication with the first water passing hole 2a3, and the mixed water can flow out from the first water outlet 1c. When the mixed water inlet end 2b2 only covers the hot water passing hole 2a2, the water flowing in the mixing channel 2b1 is all hot water, the first water passing hole 2a3 is misaligned with the mixed water inlet end 2b2 of the mixing channel 2b1 and is in a closed state, preventing the all hot water in the first water passing hole 2a3 from flowing out, ensuring user safety, and the all hot water here means that there is basically no cold water, and the first water passing hole 2a3 is completely matched with the mixed water inlet end 2b2 of the mixing channel 2b1;

[0047] When the moving valve plate 2b is switched to the second state, the mixed water inlet end 2b2 is always misaligned with the first water passing hole 2a3, and the rotation of the moving valve plate 2b can make the mixed water inlet end 2b2 rotate to cover the cold water passing hole 2a1 and the hot water passing hole 2a2, and the mixed water outlet end 2b3 is in communication with the second water passing hole 2a4, and the moving valve plate 2b in the second state can adjust the mixing ratio of cold and hot water flowing into the mixing channel 2b1 as needed during rotation, and the mixed water flows out from the second water outlet 1d (the switching process of the first state and the second state of the moving valve plate 2b can be referred to Figures 7 to 12 ).

[0048] Referring to Figure 3 , Figure 4 and Figure 6 , the valve core further includes a rotor 2c and a dial 2d arranged in sequence, the rotor 2c is rotatably installed on the valve housing 1, and the valve handle 3 is hinged to the rotor 2c, when the user operates the valve handle 3 to swing back and forth, the dial 2d can be driven to move; at the same time, the dial 2d is constrained at the bottom of the rotor 2c, it can rotate with the rotor 2c and can also slide relative to the rotor 2c. The moving valve plate 2b is fixed to the bottom surface of the dial 2d, and the static valve plate 2a is fixed to the bottom of the valve core cavity 1e, the sliding of the moving valve plate 2b realizes the switching between the first state and the second state, and the rotation of the moving valve plate 2b is used to adjust the mixing ratio of cold water and hot water.

[0049] The structure of the valve housing is as follows: referring to Figure 3 and Figure 4As shown, the valve housing 1 is composed of a shell 11 and a valve seat 12, the shell 11 is detachably connected to the valve seat 12 through a detachable structure, which includes a buckle groove 11a provided on the shell 11 and a clasp 12a provided on the valve seat 12 and capable of fitting the buckle groove 11a, at the same time, the shell 11 is provided with a positioning groove 11b, and the valve seat 12 is provided with a positioning block 12b capable of fitting in the positioning groove 11b, to ensure the accuracy of installation. The upper end of the valve handle 3 is exposed on the top of the shell 11, which is convenient for users to operate. The cold water inlet 1a, the hot water inlet 1b, the first water outlet 1c and the second water outlet 1d are all arranged on the valve seat 12, and the shell 11 is formed with an upper and lower penetrating mounting hole 11c, the rotor 2c is rotatably arranged in the mounting hole 11c, and the lower end of the valve handle 3 is connected to the dial 2d, so that the user can conveniently drive the dial 2d to move or rotate when operating the valve handle 3.

[0050] In embodiment 1, the specific structure of the water passing hole is as follows: referring to Figures 3 to 5 As shown, the first water passing hole 2a3 is located in the middle of the static valve plate 2a, the cold water passing hole 2a1, the hot water passing hole 2a2 and the second water passing hole 2a4 are spaced apart along the circumference of the static valve plate 2a and jointly surround the outer periphery of the first water passing hole 2a3. The cold water passing hole 2a1, the hot water passing hole 2a2 and the second water passing hole 2a4 all extend along the circumference of the static valve plate 2a and are formed into long and narrow arc-shaped grooves, which is beneficial to increase the water passing area and make the water flow more smoothly. The water outlet end of the first water passing hole 2a3 is further formed with an expansion area 2a5 for expanding the water receiving area of the first water passing hole 2a3 to facilitate the communication with the mixed water inlet end 2b2 of the mixing channel 2b1, further improving the water flow conduction efficiency.

[0053] Figures 10 to 12The dynamic valve plate 2b is in the second state, that is, it has been switched to the manual water outlet mode, mainly by swinging the valve handle 3 to drive the dynamic valve plate 2b to move and switch, in this mode, the cold and hot water mixed water of the valve core can be normally adjusted, in this state, the mixed water inlet end 2b2 and the first water passing hole 2a3 are always in a misaligned state, Figure 10 The dynamic valve plate 2b is swung to the second state and rotated to the position of 0°, at this time, the second water passing hole 2a4 is in a conductive state, and the cold and hot water ratio in the mixed channel 2b1 remains consistent; Figure 11 The dynamic valve plate 2b is swung to the second state and rotated to the position of 45° clockwise, at this time, the mixed channel 2b1 is in a full hot water state, and the second water passing hole 2a4 is also in a conductive state.

For details, please refer to Figures 13 to 15 As shown, the dynamic valve plate 2b is provided with a mixed channel 2b1, and the two ends of the mixed channel 2b1 form a mixed water inlet end 2b2 and a mixed water outlet end 2b3 respectively; in the first state of the dynamic valve plate 2b sliding switch, the mixed water inlet end 2b2 and the first water passing hole 2a3 are always in a misaligned state; the rotation of the dynamic valve plate 2b can make the mixed water inlet end 2b2 rotate to cover the cold water passing hole 2a1 and the hot water passing hole 2a2 to adjust the cold and hot water mixing ratio flowing into the mixed channel 2b1, and the mixed water outlet end 2b3 can be in conductive with the second water passing hole 2a4; when the dynamic valve plate 2b is rotated to the position where the mixed water inlet end 2b2 only covers the hot water passing hole 2a2, at this time, the water flow in the mixed channel 2b1 is full hot water, and the mixed water outlet end 2b3 is misaligned with the second water passing hole 2a4 and is in a closed state.

[0056] In the second state of the sliding switch of the moving valve plate 2b, the mixed outlet 2b3 and the second water passage 2a4 are always in a misaligned state, and the rotation of the moving valve plate can make the mixed inlet 2b2 rotate to cover between the cold water passage 2a1 and the hot water passage 2a2, and the mixed outlet 2b3 is connected to the first water passage 2a3.

Similarly, the cold water passage 2a1, the hot water passage 2a2 and the second water passage 2a4 also extend along the circumference of the static valve plate 2a and are formed as long and narrow arc-shaped grooves, and the outlet of the first water passage 2a3 is also formed with an expansion area 2a5 to expand the water receiving area of the first water passage 2a3 to facilitate the communication with the mixed inlet 2b2 of the mixed channel 2b1.

[0058] The working principle of the two-in and two-out valve core in the embodiment 2 is as follows:
