Description

Technical Field

[0001] The present invention relates to the technical field of bathroom appliances, in particular to a novel water valve. Background Art

[0002] Water valves, commonly known as faucets, are primarily used to control the flow of water and conserve water. Faucets are rapidly evolving, evolving from traditional cast iron models to electroplated knobs, and further to stainless steel single-temperature, single-control faucets, dual-temperature, dual-control faucets, and semi-automatic kitchen faucets. Today, more and more consumers consider a variety of factors when purchasing faucets, including material, function, and design.

[0003] Water valves are essential items for every household, and generally a single family needs to be equipped with more than 5 water valves. With the development of the Internet of Things, smart water valves have basically been popularized in third- and fourth-tier cities. Rotating the water valve left and right to adjust the water temperature and flow rate is very convenient. However, for families raising young children, smart water valves have major disadvantages. A simple turn of the water valve may quickly adjust the hot water, and it is easy to accidentally touch and scald the child. Therefore, based on this situation, a new type of water valve needs to be designed. Summary of the Invention

[0007] A protective assembly, the protective assembly includes a limiting rail, a protective handle and a limiting part, the protective handle is connected to the limiting part, and the protective handle is configured to adjust the limiting part to enter / exit the limiting rail. When the limiting part is located in the limiting rail, the valve core is in a first state. When the limiting part is separated from the limiting rail or after the limiting part is separated from the limiting rail, the valve core is in a second state.

[0008] Preferably, the second shell is rotated with the valve core through the connecting portion to drive the valve core, and a recessed portion is formed on the side end of the first shell to constitute the arc-shaped limiting track. The arc of the first shell rotation that drives the valve core to enter the second state is greater than the arc of the arc track.

[0012] Preferably, the reset plate is formed with active teeth, and the movable plate is formed with driven teeth. When the valve core is in the second state or after being in the second state, the active teeth drive the driven teeth to perform circular motion to drive the movable plate to rotate.

[0013] Preferably, a first positioning tooth is formed on a side of the movable plate opposite to the driven tooth, and a second positioning tooth is formed on a side of the fixed plate close to the movable plate, and the second positioning tooth is configured to limit the rotation angle of the first positioning tooth.

[0019] 2. The present invention utilizes the original structure for improvement. For the first shell, the mold does not need to be significantly changed on the original basis to be completed. For production, it greatly saves production costs and production time, and can be assembled using the original production line, thereby increasing profit margins.

[0020] 3. The reset component designed in the present invention can further provide safety protection. Older children have strong imitation ability and are capable of operating some simple machines. When they imitate adults driving the protective component to enter the second state, the reset component will automatically reset the second shell when they let go, thereby closing the water valve to prevent hot water from continuing to flow out.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] The embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0039] Example 1:

[0040] A new type of water valve of the present invention includes a first shell 100, which is formed with a receiving chamber 110 and a water flow chamber 120; it can be understood that the external structure required by the faucet, the receiving chamber 110 is a space for accommodating the integral components, and its position and size need to be determined by taking into account the functions of the faucet and the mechanical structure required to achieve such functions. The water flow chamber 120 is a chamber inside the first shell 100 designed to match the functions required by the faucet, for connecting different water channels to achieve different water discharge effects, specifically, as Figure 3 As shown, the middle position on the right side of the first shell 100 extends outward to form a cylindrical space, which is the accommodating chamber 110. The right side of the accommodating chamber 110 is open to facilitate the installation of parts. The first shell 100 is formed with several water supply channels in the upper and lower directions, which are the water flow chambers 120.

[0041] The valve core 200 is located in the accommodating chamber 110 of the first shell 100 and is connected to the water flow chamber 120. The valve core 200 is used to realize the connection / blocking of different passages in the water flow chamber 120; the valve core 200 is a relatively mature existing technology. Generally, different types of valve cores 200 are selected according to the required functions of the faucet and the specific operation method. Its main function is to change the connection method between different water passages in the water flow chamber 120, which will not be elaborated here.

[0042] The operating assembly 300 includes a second housing 310 and a connecting portion 320. The connecting portion 320 is connected to the valve core 200, and the second housing 310 is driven to drive the connecting portion 320 to control the valve core 200 to achieve the connection / blocking of different passages in the water flow chamber 120. It can be understood that when the faucet adjusts the flow rate, temperature or other changes, the valve core 200 needs to change the connection form of the water inlet end to achieve it. That is to say, the main function of the second housing 310 is to provide the user with a position state of the second housing 310 to control the connection state of the valve core 200 and the water flow chamber 120 through the connecting portion 320. Specifically, Figure 1 As shown, the second housing 310 is located on the right side of the first housing 100. Figure 3 As shown, the second shell 310 includes a cylindrical main body part and a handle 311 part, a chamber is formed inside the main body part, the connecting part 320 is located in this chamber, the connecting part 320 includes a connecting rod, the main body part is formed with an outer protrusion structure, the outer protrusion structure forms a card slot, one end of the connecting rod is adapted to be snapped into the card slot, and in addition, a threaded hole is also provided in the outer protrusion structure to facilitate positioning of one end of the connecting rod by a bolt.

[0043] The water flow chamber 120 includes a first water inlet passage 121, a first water outlet passage 122, a second water outlet passage 123 and a third water outlet passage 124. The second water outlet passage 123 can be connected to the third water outlet passage 124 through a temperature control unit. The water inlet end of the valve core 200 is defined as being connected to the first water inlet passage 121 and the second water inlet passage, and the water outlet end is connected to the first water outlet passage 122 as a first state. The water inlet end of the valve core 200 is connected to the first water inlet passage 121, and the water outlet end is connected to the second water outlet passage 122. The water outlet passage 123 is in the second state, that is, the water flow chamber 120 as a whole can be divided into two categories. The first category is that the water inlet end is the first water inlet passage 121, and the water flows out through the first water outlet passage 122 after passing through the valve core 200. The second category is that the water inlet end is the first water inlet passage 121, and the water flows out through the second water outlet passage 123 after passing through the valve core 200, and then the water flows into the third water outlet passage 124 after passing through the temperature control unit to achieve different water outlet requirements.

[0044] Specifically, such as Figure 2 As shown, the first water inlet passage 121 includes a cold water passage and a hot water passage, which are respectively a separate passage and each communicates with the valve core 200. The third water outlet passage 124 is a through passage at the center position of the first shell 100. The cold water passage and the hot water passage are respectively located on both sides of the third water outlet passage 124. Figure 3As shown, the second water outlet passage 123 is located on the right side of the third water outlet passage 124, that is, close to the spool 200. Although the structure of the cold water passage and the hot water passage is not shown in the figure, it can be understood that the cold water passage and the hot water passage are basically the same as the structure of the second water outlet passage 123, that is, both have a vertical first section and a second section communicating with the first section, and the second section communicates with the spool 200. Different from the second water outlet passage 123, the first section of the cold water passage and the hot water passage is longer, such as Figure 3 As shown, one end of the first water outlet passage 122 is connected to the spool 200, and the other end is output from the first shell 100. Different from this, one end of the second water outlet passage 123 is connected to the spool 200, and the other end is a connection end connected to the temperature control device such as a constant temperature hot water device or a constant temperature cold water device through a connecting pipe. The temperature control device is connected to the third water outlet passage 124, and the temperature control device can be an internal device or an external device.

[0045] In specific implementation, in the first state, that is, the state of using warm water, the input end of the spool 200 is connected to the hot water passage and the cold water passage by operating the assembly 300, and the output end of the spool 200 is connected to the first water outlet passage 122. At this time, the water flow of the first water outlet passage 122 is mixed warm water suitable for adults and children in daily use. In the second state, that is, in the case of using an external device, the input end of the spool 200 is connected to the cold water passage by operating the assembly 300, and the output end of the spool 200 is connected to the second water outlet passage 123. At this time, the second water outlet passage 123 is connected to the third water outlet passage 124 through the temperature control device, which is suitable for the mode of preventing general use, such as constant high temperature water and constant low temperature water in the second state.

[0046] The protection assembly 400 includes a limiting track 410, a protection handle 420 and a limiting part 430. The protection handle 420 is connected to the limiting part 430. The protection handle 420 is configured to adjust the limiting part 430 to enter or leave the limiting track 410. When the limiting part 430 is located in the limiting track 410, the valve core 200 is in the first state. When the limiting part 430 leaves the limiting track 410 or after the limiting part 430 leaves the limiting track 410, the valve core 200 is in the second state. It is generally understood that the child lock state is that, in the case of opening the child lock, the valve core 200 is in the second state. At this time, high-temperature or low-temperature water can flow out. That is, when the valve core 200 is in the first state, the limiting part 430 is located in the limiting track 410. At this time, the mixed warm water in the first state can be used at will. That is, the flow rates of the cold water passage and the hot water passage are adjusted to obtain hot water within a certain temperature range. Generally, the temperature does not exceed the limit temperature that the human body can receive. The limiting track 410 mechanically limits the movement range of the limiting part 430. When in the first state, the protection handle 420 is connected to the limiting part 430. It is subjected to a force that maintains its position in the limiting track 410. When it is necessary to enter the second state, the protection handle 420 is subjected to a force that changes its position, thereby causing it to drive the limiting part 430 to leave the limiting track 410. At this time, the second shell 310 is in a different position than in the first state, thereby causing the valve core 200 to achieve different pipeline connections.

[0047] The second shell 310 is connected to the valve core 200 by the connecting part 320 to drive the valve core 200. The side end of the first shell 100 is formed with a recessed part to form an arc-shaped limiting track 410. The arc of the first shell 100 that drives the valve core 200 to enter the second state is greater than the arc of the arc-shaped track. That is, the faucet is opened and closed by rotating the second shell 310 to control the valve core 200. The second track is an arc-shaped notch formed on one side of the first shell 100. In the first state, the limiting part 430 is limited to movement within the arc-shaped track. The arc-shaped track with a concave shape cooperates with the conventional rotation of the second shell 310 to achieve waterway control. It can be modified on the conventional structure and developed on the basis of the mold. It can reduce a large amount of cost investment in the production link. Even the original mold can be used for production. In addition, it does not need to increase other structural parts, and it makes more rational use of limited space. It is perfectly adapted to the existing structure, does not need to change the user's usage habit, has better market promotion ability, and can achieve good protection effect from the side through different arcs (i.e., the positions of the connecting part 320 when opening the first state and the second state). That is, in a smaller arc, it is warm water, and in a larger arc, it is constant-temperature or high-temperature water. It also has an embodiment, that is, it is only high-temperature or constant-temperature water when it reaches 90°. In this case, the specific angle of the high-temperature water is limited based on the protection assembly 400, which is more distinguishable.

[0048] In some embodiments, after the limiting portion 430 is separated from the limiting track 410, the wall of the first housing 100 exerts a force on the limiting portion 430 to maintain its position. In other words, in the second state, the limiting portion 430 is separated from the original limiting track 410, and a new track is formed in the first housing 100. At this time, the limiting portion 430 is located in this new track, allowing it to stay in any position.

[0049] In other embodiments, unlike the above, the second housing 310 includes a handle 311, the protective assembly 400 further includes a first elastic member 440, a slide groove is formed in the second housing 310, and the protective handle 420 is connected to the first elastic member 440 and installed in the slide groove. The second housing 310 forms an auxiliary slide rail 312 along the direction in which the limiting portion 430 disengages from the limiting slide rail, and one end of the limiting portion 430 is located within the auxiliary slide rail 312. In other words, the first elastic member 440 is connected to the protective handle 420. After the protective handle 420 drives the limiting portion 430 to disengage from the limiting rail 410, the elastic member exerts a force on the limiting portion 430 to return to the extended position of the limiting rail 410. At this time, the limiting portion 430 cannot return to the circumference of the limiting rail 410 due to the obstruction of the first housing 100. The first elastic member 440 cooperates with the first housing 100 to maintain its position after disengaging from the limiting rail 410.

[0050] Specifically, such as Figure 3 As shown, in the initial position, the handle 311 is in a vertical position, a cavity is formed in the handle 311, the protective handle 420 is located in the cavity, and both ends pass through the cavity, the upper end is a pressing position, and the lower end is connected to the limiting portion 430, that is, the limiting rod. The limiting rod is arranged horizontally and is detachably connected to the protective handle 420. The limiting rod is located in the cavity of the shell. It can be seen that a first elastic member 440, that is, a spring, is installed around the protective handle 420. Figure 4, an arc-shaped notch is formed on the upper right edge of the first shell 100, the arc angle of the arc-shaped notch is 120°, and in other embodiments, it can also be 100°, 145°, 135°, 90°, 105°, etc. This notch is the limit track 410. In the initial position, the limit rod is located in the middle position of the arc track, and it can move freely within the arc of the arc track. At this time, the valve core 200 is controlled by the connecting rod to be in the first state, and then warm water mixed with hot and cold water flows out of the first water outlet passage 122, and the flow of hot and cold water at the input end of the valve core 200 is regulated by rotating left and right, so as to achieve the change of the warm water temperature within a certain temperature threshold. After pressing the protective handle 420, the protective handle 420 drives the limit rod 420 to move. The positioning rod moves downward, at this time it is the state of closing the child lock, the diameter of the circumferential track of the movement of the limiting rod is smaller than the diameter of the circumference when it moves on the limiting track 410, the first elastic member 440 gives the limiting rod a force to return to the circumference of the limiting track 410, and when the arc of its movement is greater than the arc of the limiting track 410, the right side wall of the first shell 100 acts as an obstacle to prevent the limiting rod from returning to the circumference of the limiting track 410, and at this time cooperates with the valve core 200 to reach the second state, at this time the water outlet end of the valve core 200 is connected to the second water outlet passage 123, and the water flow is heated or cooled to a certain temperature through an external temperature control unit. Under normal circumstances, the temperature at this time is 70-98 degrees Celsius, or 1-10 degrees Celsius, which is not suitable for children to touch. In addition, refer to Figure 4 The second shell 310 has an auxiliary slide rail 312 in its body. The auxiliary slide rail 312 has a vertical groove. One end of the limit rod is located in this groove, thereby ensuring that its moving track is certain while preventing it from being subjected to unidirectional torque, reducing the risk of its breakage and increasing its service life.

[0051] Example 2:

[0052] Due to the difference of the valve core 200, if you want to enter the first state, you need to move the handle 311 to the right by a certain angle ( Figure 3 Perspective as an example), the valve core 200 is rotated clockwise or counterclockwise along its rotation direction so that it is in the first state. At this time, warm water flows out. It should be noted that this embodiment is consistent with the above structure. Therefore, the limit rod is limited by the limit track 410 and can still only move within 120° of the limit track 410, and generally rotates in the left and right directions at the same time, that is, it has an effective rotation direction of 60°. The difference is that when the handle 311 does not move outward, that is, when it is rotated clockwise or counterclockwise in a vertical state, it does not discharge water within the arc of the limit track 410. This method adds a difference between the normal use of warm water and the use of constant temperature hot water / cold water, which is more recognizable and more conducive to preventing babies from being scalded by misoperation.

[0053] In addition, in some embodiments, the water passage chamber 120 further includes a closed chamber formed in the first shell 100, such as Figure 3 As shown, the underside of the closed chamber has threads to facilitate installation of the filter device in the closed chamber.

[0054] Example 3:

[0055] Different from Example 1 and Example 2, on the basis of Example 1 or Example 2, a reset assembly 500 is further included. The reset assembly 500 includes a fixed plate 510, a movable plate 520, a second elastic member 530 and a reset plate 540 arranged in the accommodating chamber 110. The reset plate 540 is movably connected to the connecting portion 320. When the connecting portion 320 rotates, it can drive the reset plate 540 to rotate. The second elastic member 530 connects the fixed plate 510 and the movable plate 520. When the valve core 200 is in the second state or after being in the second state, when the reset plate 540 rotates, it drives the movable plate 520 to move relative to the fixed plate 510, so as to change the elastic potential energy of the second elastic member 530.

[0056] That is to say, after the arc of the displacement of the limit rod driven by the second shell 310 is greater than the arc of the limit track 410 in one direction, since the connecting rod is driving the reset plate 540 to rotate at the same time, after the arc is greater than the above-mentioned arc, the reset plate 540 will drive the movable plate 520 to rotate. At this time, the fixed plate 510 is stationary, and then the shape of the second elastic member 530 is changed to obtain the elastic potential energy of reset, that is, when the second shell 310 rotates more than 60° in one direction, it will obtain a reset elastic potential energy, so that it will automatically return to its position after releasing the hand.

[0057] The reset plate 540 is formed with a driving tooth 541, and the movable plate 520 is formed with a driven tooth 521. When the valve core 200 is in the second state or after being in the second state, the driving tooth 541 drives the driven tooth 521 to make a circular motion to drive the movable plate 520 to rotate. In other words, there is a spaced driving structure between the reset plate 540 and the movable plate 520. The reset plate 540 drives the driven tooth 521 on the side of the movable plate 520 close to the reset plate 540 through the driving tooth 541 close to the movable plate 520. It should be noted that in the initial state, the driving tooth 541 and the driven tooth 521 are not adjacent to each other, but are arranged in a spaced and evenly structure. Specifically, Figure 6 As shown, the outer periphery of the reset plate 540 is provided with three driving teeth 541 in a circular array with its center as the center point, and the inner side of the movable plate 520 is provided with three driven teeth 521 in a circular array with its center point as the center point. In the initial state, every two adjacent driving teeth 541 and driven teeth 521 are spaced 60° apart.

[0058] In other embodiments, the initial rotation angle can be changed by adjusting the arrangement of the individual driven teeth 521, the arrangement of the individual driving teeth 541, and the relative positions of the driven teeth 521 and the driving teeth 541. For example, if two driving teeth 541 are symmetrically arranged on the outer periphery of the reset plate 540, and two driven teeth 521 are symmetrically arranged on the inner side of the movable plate 520, in the initial state, the arc between adjacent driven teeth 521 and driving teeth 541 is 45°, that is, within 45° of rotation of the second shell 310, it will not be affected by the reset assembly 500.

[0059] Unlike the 60° interval, when it is used in conjunction with Example 1, when the rotation arc is between 45-60°, the temperature of the mixed warm water is generally higher than that within 45°. Therefore, it can prevent young children from being scalded when using mixed warm water to a certain extent, and play the role of an auxiliary protection component 400 child lock. When the rotation arc is between 45-60°, the reset plate 540 and the movable plate are affected by the second elastic member 530 and can return to the 45° position. After use, the user can rotate the second shell 310 back to the origin.

[0060] When it is used in conjunction with Example 2, when the arc of direct clockwise or counterclockwise rotation is between 45-60°, it will not discharge mixed warm water. When it is broken open outward and rotated between 45-60° clockwise or counterclockwise, it will also be affected by elastic potential energy. Therefore, under higher temperature conditions, it plays a better protective role and greatly increases the safety of use.
