[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0037] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0038] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0039] See also Figures 1 to 11 As shown, according to an embodiment of the present invention, a quantitative device is provided, comprising a housing 1 and a quantitative mechanism, wherein a flow channel is formed in the housing 1, and the quantitative mechanism is installed in the housing 1; the quantitative mechanism has a diversion state and a shut-off state, and when the quantitative mechanism is in the diversion state, the fluid flows in the flow channel; when the flow rate of the fluid in the flow channel reaches a set value, the quantitative mechanism automatically switches from the diversion state to the shut-off state under the impact of the fluid to shut off the flow of the fluid in the flow channel.

[0040] In this technical solution, when the quantitative device of the present application is applied to the faucet of the water purifier, since the quantitative mechanism of the quantitative device can automatically switch from the diversion state to the interception state under the impact of the fluid to cut off the flow of the fluid in the quantitative device, the water purifier using the quantitative device of the present application does not need to consume any electrical energy when achieving quantitative water output, thereby not causing energy consumption and carbon emissions, and is more energy-saving and environmentally friendly.

[0041] See also Figure 1 、 Figure 2 and Figure 9 As shown, the housing 1 has an inlet port 2 , to which the flow channel extends; and / or the housing 1 has an outlet port 3 , to which the flow channel extends.

[0042] In this embodiment, the existing electric-controlled faucet with quantitative water output needs to be matched with an interface with an outlet terminal, and the water purifier that has been sold to the user cannot directly upgrade the electronic control device. The quantitative device of this application is a mechanical structure and has an inlet interface 2. Therefore, for the water purifier that has been sold, it is only necessary to insert the inlet interface 2 of the quantitative device into the faucet of the water purifier to enable the water purifier to have the function of quantitative water output. Furthermore, since the quantitative device also has an outlet interface 3, the quantitative device of this application can be installed not only at the front end of the faucet, but also in the middle of the faucet, such as Figure 10 and Figure 11 shown.

[0043] See also Figures 1 to 4As shown, the quantitative mechanism includes an operating shaft 4, a lock head 5, a locking mating assembly 6 and a sealing component 7. The operating shaft 4, the lock head 5, the locking mating assembly 6 and the sealing component 7 are all located in the housing 1. The lock head 5 is arranged on the operating shaft 4. The sealing component 7 and the locking mating assembly 6 are both sleeved on the periphery of the operating shaft 4. The operating shaft 4 has a first position and a second position. The sealing component 7 has a conducting position for conducting the flow channel and a sealing position for sealing the flow channel. When the operating shaft 4 is in the first position, the lock head 5 and the locking mating assembly 6 are locked and matched, and the sealing component 7 is in the conducting position, and the fluid circulates in the flow channel; when the flow rate of the fluid in the flow channel reaches a set value, the lock head 5 and the locking mating assembly 6 are automatically unlocked under the impact of the fluid, so that the operating shaft 4 automatically switches from the first position to the second position and the sealing component 7 automatically switches from the conducting position to the sealing position, and the flow of the fluid in the flow channel is cut off.

[0044] In this technical solution, when the operating shaft 4 is in the first position, the lock head 5 and the locking assembly 6 are locked and matched, and the sealing component 7 is in the conducting position, which is equivalent to the quantitative mechanism being in a diversion state, and the water flow can continue to circulate in the flow channel. When the water flow in the flow channel reaches the set value, that is, after the quantitative water discharge is achieved, the lock head 5 and the locking assembly 6 are automatically unlocked under the action of water, so that the operating shaft 4 automatically switches to the second position and the sealing component 7 automatically switches to the sealing position, which is equivalent to the quantitative mechanism automatically switching to the intercepting state under the action of water flow. In other words, this application achieves quantitative water discharge through a simple mechanical structure and water flow, thereby also making it possible to achieve quantitative water discharge without the need for electronic control and without consuming electricity.

[0045] See also Figures 1 to 8 As shown, the locking assembly 6 includes a water wheel 61 and an elastic body 62. Both water wheel 61 and elastic body 62 are sleeved around the periphery of the operating shaft 4. The front end of the water wheel 61 faces the incoming fluid flow direction. Under the impact of the fluid, the water wheel 61 can rotate relative to the operating shaft 4. The elastic body 62 is fixed to the rear end of the water wheel 61 and is configured with a lock hole 8. When the operating shaft 4 is in the first position, the lock head 5 is inserted into the lock hole 8. When the flow rate of the fluid in the flow channel reaches a set value, the water wheel 61 causes the elastic body 62 to deform to a set deformation degree during rotation, so that the lock head 5 automatically disengages the lock hole 8, and the operating shaft 4 automatically switches from the first position to the second position.

[0046] In this embodiment, when the operating shaft 4 is in the first position, driving the lock head 5 to be inserted into the lock hole 8 so that the lock head 5 and the elastic body 62 are locked, and the sealing component 7 is in the conducting position, water flows through the flow channel of the housing 1. Because the water wheel 61 can rotate relative to the operating shaft 4 under the impact of the water flow, and the elastic body 62 is fixed to the tail end of the water wheel 61, the water wheel 61 causes the elastic body 62 to twist and deform during rotation. When the elastic body 62 twists and deforms to a certain extent, the lock head 5 automatically disengages from the lock hole 8, and the lock head 5 and the elastic body 62 are automatically unlocked, causing the operating shaft 4 to automatically switch to the second position and the sealing component 7 to automatically switch to the sealing position, thus cutting off the flow of fluid in the flow channel. The time from the time when the water wheel 61 causes the elastic body 62 to begin to twist and deform until the elastic body 62 deforms to a certain extent, causing the lock head 5 to disengage from the lock hole 8, represents a certain amount of water flowing through, thereby achieving automatic flow cutoff of the metering device after the metered water is discharged.

[0047] See also Figures 1 to 4 As shown, a bearing 9 is fixedly provided in the flow channel, the tail end of the water wheel 61 is fixed on the inner ring body of the bearing 9 , and the water wheel 61 is clearance-fitted with the operating shaft 4 .

[0048] In this technical solution, when the tail end of the water wheel 61 is fixed on the inner ring body of the bearing 9 and the water wheel 61 is clearance-fitted with the operating shaft 4, there is no friction between the water wheel 61 and the operating shaft 4, and the water wheel 61 is more likely to rotate under the impact of the water flow, thereby more easily driving the elastic body 62 to deform.

[0049] See also Figure 7 and Figure 8 As shown, the elastic body 62 is a coil spring, the outermost circle of the coil spring is fixed to the tail end of the water wheel 61, and the lock hole 8 is constructed on the innermost circle of the coil spring.

[0050] In this embodiment, when the elastic body 62 is a coil spring, the water wheel 61 can be pre-designed so that after the coil spring is rotated a specific number of times, the coil spring will deform to the extent that the lock head 5 can be released from the lock hole 8 on the coil spring. This ensures the accuracy of the metered water discharge, as the specific number of turns corresponds to a fixed amount of water. Preferably, the axial length of the innermost coil spring is greater than the axial length of the outermost coil spring. This allows the innermost coil spring to extend beyond the outermost coil spring, thereby facilitating the lock head 5 to be inserted into or released from the lock hole 8 of the innermost coil spring.

[0051] See also Figures 1 to 4As shown, a mounting groove is constructed on the operating shaft 4, and the lock head 5 can be slidably arranged in the mounting groove. A first elastic component 10 is also provided in the mounting groove. One end of the first elastic component 10 is connected to the groove wall of the mounting groove, and the other end of the first elastic component 10 is connected to the lock head 5. The lock head 5 extends radially along the operating shaft 4. When the operating shaft 4 is in the second position, the lock head 5 is on the side of the elastic body 62 away from the water wheel 61, and the lock head 5 has a portion outside the mounting groove under the action of the first elastic component 10.

[0052] In this technical solution, when the operating shaft 4 switches from the second position to the first position, the operating shaft 4 drives the lock head 5 toward the coil spring. When the lock head 5 contacts the innermost coil spring, the innermost coil spring applies force to the lock head 5, causing it to slide into the mounting slot. Simultaneously, the first elastic component 10 is compressed. When the lock head 5 reaches the keyhole 8, the compressed first elastic component 10 drives the lock head 5 into the keyhole 8, thereby locking the lock head 5 with the coil spring. In other words, the provision of the first elastic component 10 enables the lock head 5 to lock with the coil spring and automatically reset the lock head 5 after unlocking. Of course, if the lock head 5 is inherently elastic, the first elastic component 10 is not necessary; the inherent elasticity of the lock head 5 alone can achieve locking with the coil spring and automatic reset after unlocking. The first elastic component 10 can be a spring.

[0053] See also Figure 1 and Figure 2 As shown, one end of the operating shaft 4 is connected to a quantitative button 11, which has a portion outside the housing 1. A second elastic component 12 is provided in the housing 1. The quantitative button 11 has a pressed state and a reset state. When the quantitative button 11 is in the pressed state, the quantitative button 11 drives the operating shaft 4 to the first position, the operating shaft 4 drives the lock head 5 to lock and cooperate with the locking mating component 6, and the sealing component 7 is in the conducting position; after the lock head 5 and the locking mating component 6 are automatically unlocked under the impact of the fluid, the quantitative button 11 automatically switches from the pressed state to the reset state under the action of the second elastic component 12, the operating shaft 4 automatically switches from the first position to the second position under the drive of the quantitative button 11, and the sealing component 7 automatically switches from the conducting position to the sealing position.

[0054] In this embodiment, the provision of a dosing button 11 facilitates the operator's operation of the dosing device. When the operator presses the dosing button 11, the dosing button 11 drives the operating shaft 4 and the lock head 5 to engage, thereby locking the lock head 5 with the locking mating assembly 6 and placing the sealing component 7 in the conducting position, thereby allowing water to flow through the dosing device. The provision of a second elastic component 12 automatically unlocks the lock head 5 and the locking mating assembly 6 under the action of the water flow. The second elastic component 12 applies the elastic force of the dosing button 11, causing the dosing button 11 to automatically reset. During the reset process, the dosing button 11 drives the operating shaft 4 to automatically switch to the second position and the sealing component 7 to automatically switch to the sealing position, thereby achieving automatic flow interception of the dosing device.

[0055] See also Figure 1 and Figure 2 As shown, the shell 1 also has an isolation chamber 13, which is isolated from the flow channel. The second elastic component 12 is arranged in the isolation chamber 13. One end of the operating shaft 4 extends into the isolation chamber 13 and is connected to the quantitative button 11. The second elastic component 12 is clamped between the quantitative button 11 and the wall of the isolation chamber 13.

[0056] In this technical solution, since the dosing button 11 has a portion outside the housing 1 and is a movable component, a gap exists between the dosing button 11 and the housing 1. The provision of an isolation chamber 13, isolated from the flow channel, prevents water within the dosing device from leaking through the gap between the dosing button 11 and the housing 1. The provision of the isolation chamber 13 also facilitates the installation of the second elastic component 12. When the operating shaft 4 is in the second position, the lock head 5 is located between the elastic body 62 and the isolation chamber 13. The second elastic component 12 may be a spring.

[0057] See also Figure 1 As shown, the sealing component 7 is located upstream of the fluid flow relative to the locking mating assembly 6. When the operating shaft 4 is in the first position, the sealing component 7 automatically switches from the sealing position to the conducting position under the impact of the fluid.

[0058] In this embodiment, when the sealing component 7 automatically switches to the conducting position under the impact of the fluid, it is possible to avoid the use of mechanical linkage to drive the sealing component to conduct the flow path, thereby avoiding the failure of the sealing component to conduct the flow path due to failure of the mechanical linkage.

[0059] See also Figures 1 to 4As shown, a stopper 14 is mounted on the operating shaft 4. The housing 1 further includes a mounting chamber 15 located on the flow path of the flow channel. The mounting chamber 15 has an inlet and an outlet. The operating shaft 4 extends through the mounting chamber 15. The sealing component 7 is located between the inlet and the stopper 14, and the sealing component 7 and the operating shaft 4 have a clearance fit. When the operating shaft 4 is in the second position, the sealing component 7 is clamped between the inlet and the stopper 14 to seal the inlet. When the operating shaft 4 is in the first position, the stopper 14 moves away from the inlet, and the sealing component 7 automatically opens the inlet under the impact of the fluid.

[0060] In this technical solution, when the operating shaft 4 is in the first position, the stopper 14 is driven by the operating shaft 4 to displace in a direction away from the entrance of the installation chamber 15. Therefore, the stopper 14 temporarily loses its ability to stop the sealing component 7, and the water flow will impact the sealing component 7, thereby causing the sealing component 7 to also move in a direction away from the entrance of the installation chamber 15. The entrance is then opened, and water flows through the metering device. When the operating shaft 4 is switched from the first position to the second position, the stopper 14 is driven by the operating shaft 4 to displace in a direction closer to the entrance of the installation chamber 15. Therefore, the stopper 14 will abut the sealing component 7 so that the sealing component 7 seals the entrance of the installation chamber 15. The entrance is then closed, and the metering device intercepts water. It should be noted that the stopper 14 also has a sealing function. When the stopper 14 abuts the sealing component 7 so that the sealing component 7 seals the entrance of the installation chamber 15, the stopper 14 also forms a seal on the gap between the sealing component 7 and the operating shaft 4, thereby ensuring that water does not pass through the gap between the sealing component 7 and the operating shaft 4.

[0061] See also Figure 1 and Figure 2 As shown, the housing 1 further has a side wall opposite to the inlet, with a distance between the side wall and the inlet. A third elastic component 16 is provided on the side of the sealing component 7 facing away from the inlet, and the third elastic component 16 is clamped between the sealing component 7 and the side wall.

[0062] In this embodiment, the third elastic component 16 is provided so that when the operating shaft 4 is in the second position, not only does the stopper 14 abut the sealing component 7, but the third elastic component 16 also abuts the sealing component 7, thereby further ensuring that the sealing component 7 seals the entrance to the installation chamber 15. It will be appreciated that when the operating shaft 4 is in the first position, the impact force of the water flow is greater than the elastic force applied to the sealing component 7 by the third elastic component 16. Therefore, the water flow is not affected in causing the sealing component 7 to automatically open the entrance to the installation chamber 15. The third elastic component 16 may be a spring.

[0063] See also Figure 1As shown, the orientation of the inlet of the mounting chamber 15 is perpendicular to the extension direction of the inlet port 2. This means that after entering the inlet port 2, the water flow must change direction before impacting the sealing component 7. When the operating shaft 4 is in the first position, the water flow is more likely to impact and displace the sealing component 7. It should be noted that the sealing component 7 is larger than the inlet of the mounting chamber 15. This increases the impact area of ​​the water flow on the sealing component 7, further making it easier for the water flow to impact and displace the sealing component 7. It should also be noted that the water wheel 61, the elastomer 62, and the bearing 9 are all located within the mounting chamber 15.

[0064] The utility model also provides a faucet, including the aforementioned quantitative device. Figure 10 and Figure 11 In the embodiment, the quantitative device is installed between the faucet valve body 18 and the faucet outlet pipe 17 of the faucet. When the faucet valve body 18 is opened, the quantitative button 11 is pressed to make the faucet discharge water in a quantitative manner.

[0065] The utility model also provides a water purifier, comprising the above-mentioned faucet.
