This not only affects the convenience of daily life but may also damage household water appliances. For example, in the shower, unstable water flow can cause the water temperature to fluctuate, affecting the comfort of bathing; when washing dishes or vegetables in the kitchen, unstable water flow can significantly reduce the cleaning effect and may even cause unnecessary waste due to splashing. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a constant flow device and a water outlet device.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A constant flow device includes an inner water outlet base with an inner mounting cavity. The bottom of the inner mounting cavity has an inner water outlet surface with a positioning hole and a plurality of inner water outlet holes. It also includes an adjusting plate, which includes a deformation plate and a positioning shaft disposed on the deformation plate. The adjusting plate has a water inlet and is mounted in the inner mounting cavity. The positioning shaft is movably disposed within the positioning hole. A flow channel is provided between the adjusting plate and the inner water outlet base. The water inlet is connected to the flow channel. The deformation plate moves up and down based on the inlet water pressure to change the flow area of ​​the flow channel.

[0006] Furthermore, the gap between the deformable plate and the inner water outlet surface forms a first flow passage cavity. The positioning shaft has a water inlet on the side near the water inlet end and a water outlet on the side of the positioning shaft. The internal cavity of the positioning shaft forms a water outlet channel. The water outlet channel, the water outlet, and the first flow passage cavity are interconnected to form the flow passage channel. The deformable plate moves up and down based on the water pressure of the inlet water, thereby driving the positioning shaft to move up and down to change the position of the water outlet, change the water flow surface connecting the water outlet and the first flow passage cavity, and thus change the water flow area of ​​the flow passage channel.

[0007] Furthermore, the inner sidewall of the inner mounting cavity is provided with a first limiting position, and the deformation plate includes a deformation body and an abutment portion provided on the outer side of the deformation body. The abutment portion abuts against the first limiting position and is sealed and adapted to the sidewall of the inner mounting cavity, so that the gap between the deformation body and the inner water outlet surface constitutes the first flow cavity.

[0008] Furthermore, the positioning shaft is provided with an anti-deformation part on the side away from the water inlet end.

[0009] Furthermore, an annular baffle is provided at the opening of the positioning hole on the side away from the water inlet, and the lower edge of the annular baffle is lower than the lower edge of the water outlet when it moves downward to its limit position.

[0010] Furthermore, the positioning shaft extends through a first flow channel along its axial direction, and the deformation plate is provided with a second flow channel communicating with the first flow cavity. The gap between the deformation plate and the inner water outlet surface constitutes the first flow cavity, and the first flow cavity constitutes the flow channel. The deformation plate moves up and down based on the magnitude of the inlet water pressure, thereby changing the size of the first flow cavity to change the water flow area of ​​the first flow cavity.

[0011] A water outlet device includes an outlet water base, the outlet water base having an external mounting cavity, the bottom of the external mounting cavity having an outlet water surface, the outlet water surface having a plurality of outlet water holes, characterized in that the external mounting cavity is provided with a constant flow device as described above, and a second flow passage cavity is provided between the inner outlet water base and the outlet water surface.

[0012] Furthermore, the outer mounting cavity sidewall is provided with a second limiting position, the inner water outlet seat abuts against the second limiting position, and the gap between the inner water outlet seat and the outer water surface constitutes the second flow passage cavity.

[0013] Furthermore, the outer water seat is provided with an air intake channel that connects to the atmospheric environment and the second flow cavity.

[0014] Furthermore, the inner mounting cavity is also provided with a filter screen, and the filter screen and the deformation plate are arranged sequentially along the water outlet direction; it also includes a pressure ring to press the filter screen and the deformation plate into the inner mounting cavity.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model proposes a constant flow device, comprising an inner water outlet seat and an adjusting plate installed within the inner water outlet seat. The inner water outlet seat has an inner water outlet surface. The adjusting plate includes a deformation plate and a positioning shaft disposed on the central axis of the deformation plate. A first flow passage cavity is provided between the deformation plate and the inner water outlet surface. The positioning shaft has a water outlet hole. In use, the deformation plate is displaced under the action of the inlet water pressure, thereby driving the positioning shaft to move up and down to change the position of the water outlet, thus changing the water passage area connecting the water outlet and the first flow passage cavity, thereby achieving a constant flow rate water output effect.

[0017] 2. The constant flow device proposed in this utility model includes a deformation plate comprising a deformation body. The inner side of the deformation body is connected to the middle of the positioning shaft. The space enclosed by the deformation plate and the outer wall of the positioning shaft constitutes a first pressure action zone. The inlet water pressure acts on the first pressure action zone, thereby pushing the positioning shaft to move downward, thereby changing the position of the outlet.

[0018] 3. The constant flow device proposed in this utility model has an internal cavity of the positioning shaft forming a second pressure action zone. The inlet water pressure acts on the second pressure action zone, further pushing the positioning shaft to move downward, thereby changing the position of the outlet.

[0019] 4. The constant flow device proposed in this utility model has an anti-deformation part on the side of the positioning shaft away from the water inlet end, so as to avoid the positioning shaft from deforming due to excessive water pressure, which would increase the gap between the positioning shaft and the positioning hole and cause the water inlet to leak from the gap, thus avoiding the constant flow effect being affected.

[0020] 5. The constant flow device proposed in this utility model has an annular baffle wall at the opening on the side of the positioning hole away from the water inlet. The lower edge of the annular baffle wall is lower than the lower edge of the water outlet when it moves downward to the limit position, so as to prevent the water flow from flowing directly out of the water outlet through the water outlet without passing through the first flow cavity and then flowing out from the bottom of the inner water outlet seat.

[0021] 6. The constant flow device proposed in this utility model has a first flow channel through which the positioning shaft passes along its axial direction, and a second flow channel connected to the first flow cavity of the deformation plate, which is used to discharge water with different flow patterns, such as bubble water and blade water. The first flow channel and the second flow channel can be connected to different water supply sources or connected to the same water supply source through a switching device. One or both of the first flow channel and the second flow channel can be opened to meet the diverse usage needs of users. Attached Figure Description

Detailed Implementation

[0040] Example 1

[0041] The following is combined with Figures 1-5 This utility model will be described in detail.

[0042] A constant flow device includes an inner water outlet seat 10, which has an inner mounting cavity 101. The bottom of the inner mounting cavity 101 has an inner water outlet surface 102, which has a positioning hole 1022 and a plurality of inner water outlet holes 1021. It also includes an adjusting plate 20, which includes a deformation plate and a positioning shaft 202 disposed on the deformation plate. The deformation plate drives the positioning shaft 202 to move in the opposite direction of the incoming water flow. The adjusting plate 20 has a water inlet 203. The adjusting plate 20 is installed in the inner mounting cavity 101. The positioning shaft 202 is movably disposed in the positioning hole 1022. A flow passage is provided between the adjusting plate 20 and the inner water outlet seat 10. The water inlet 203 is connected to the flow passage. The deformation plate moves up and down according to the magnitude of the incoming water pressure to change the water flow area of ​​the flow passage.

[0043] The gap between the deformable plate and the inner water outlet surface 102 forms the first flow passage 301. A water inlet 203 is located on the side of the positioning shaft 202 near the water inlet end, and a water outlet 204 is located on the side of the positioning shaft 202. The internal cavity of the positioning shaft 202 forms a water outlet channel 205. The water outlet channel 205, the water outlet 204, and the first flow passage 301 are interconnected to form a flow passage. In use, the deformable plate moves up and down based on the inlet water pressure, which in turn moves the positioning shaft 202 up and down to change the position of the water outlet 204, thereby changing the water flow area between the water outlet 204 and the first flow passage 301. Furthermore, as the inlet water pressure increases, the water flow area between the water outlet 204 and the first flow passage 301 gradually decreases. Figures 3-5As shown in the diagram, L gradually decreases. Specifically, when the inlet water pressure does not exceed the deformation force of the deformation plate, the deformation plate does not move up or down, and therefore does not drive the positioning shaft 202 to move up or down, and the water passage area connecting the outlet 204 and the first flow passage cavity 301 does not change; when the inlet water pressure exceeds the deformation force of the deformation plate, the deformation plate moves downward, and then drives the positioning shaft 202 to move downward, and the water passage area connecting the outlet 204 and the first flow passage cavity 301 becomes smaller, thereby achieving a constant flow rate water output effect.

[0044] In this embodiment, the inner wall of the inner mounting cavity 101 is provided with a first limiting position 401. The deformable piece includes a deformable body 2011 and an abutment portion 2012 with an outer side of the deformable body 2011. The abutment portion 2012 abuts against the first limiting position 401 and is sealed and adapted to the side wall of the inner mounting cavity 101, so that the gap between the deformable body 2011 and the inner water outlet surface 102 constitutes a first flow passage cavity 301. The first limiting position 401 is a limiting surface.

[0045] In this embodiment, as Figures 3-5 As shown, the inner side of the deformable body 2011 is connected to the middle of the positioning shaft 202, and the outlet 204 is located below the deformable body 2011. The space enclosed by the deformable plate and the outer wall of the positioning shaft 202 constitutes the first pressure action zone 501. The positioning shaft 202 has an inlet 203 on the side near the water inlet end, and an outlet 204 on the side of the positioning shaft 202. The internal cavity of the positioning shaft 202 constitutes an outlet channel 205, which in turn constitutes the second pressure action zone 502. When water enters, the water flow acts on the first pressure action zone 501 and the second pressure action zone 502 respectively, facilitating the downward movement of the positioning shaft 202 and thus changing the position of the outlet 204.

[0046] In this embodiment, the positioning shaft 202 is provided with an anti-deformation part 206 on the side away from the water inlet end to prevent the positioning shaft 202 from deforming due to excessive water pressure, which would increase the gap between the positioning shaft 202 and the positioning hole 1022 and cause the water inlet to leak from the gap, thus preventing the constant flow effect from being affected.

[0047] In this embodiment, as Figure 5 As shown, an annular baffle 103 is provided at the opening of the positioning hole 1022 on the side away from the water inlet. The lower edge of the annular baffle 103 is lower than the lower edge of the outlet 204 when it moves downward to the limit position. This prevents the water inlet from flowing directly out of the outlet 204 when part of the outlet 204 is below the inner water outlet surface 102, which would cause the constant flow effect to fail.

[0048] Example 2

[0049] The following is combined with Figures 6-10 This utility model will be described in detail.

[0050] The difference between the constant flow device proposed in this embodiment and that in Embodiment 1 is that the regulating plate 20 has a dual water path configuration. Specifically, the positioning shaft 202 has a first flow channel 2071 extending through it along its axial direction, and the deformation plate has a second flow channel 2072 communicating with the first flow cavity 301. The gap between the deformation plate and the inner water outlet surface 102 constitutes the first flow cavity 301. The first flow cavity 301 forms a flow passage. The deformation plate moves up and down based on the magnitude of the inlet water pressure, thereby changing the size of the first flow cavity 301 to change the water flow area of ​​the first flow cavity 301, such as... Figures 8-10 As shown in Figure S, S gradually decreases. Specifically, when the inlet water pressure does not exceed the deformation force of the deformation plate, the deformation plate does not move up or down, and the water passage area of ​​the first flow cavity 301 does not change; when the inlet water pressure exceeds the deformation force of the deformation plate, the deformation plate moves downward, the water passage area of ​​the first flow cavity 301 decreases, thereby achieving a constant flow rate water output effect.

[0051] In this embodiment, the first flow channel and the second flow channel 2072 are used to discharge water with different flow patterns, such as sparkling water and blade water. The first flow channel 2071 and the second flow channel 2072 can be connected to different water supply sources or connected to the same water supply source through a switching device. Opening one or both of the first flow channel 2071 and the second flow channel 2072 can meet the diverse usage needs of users.

[0052] Example 3

[0053] The following is combined with Figures 11-13 This utility model will be described in detail.

[0054] A water outlet device includes an outlet water seat 60, an outer mounting cavity 601, an outlet water surface 602 at the bottom of the outer mounting cavity 601, and an outlet water hole 603 on the outlet water surface 602. A constant flow device as described in Embodiment 1 is installed inside the outer mounting cavity 601. A second flow passage 302 is provided between the inner outlet water seat 10 and the outlet water surface 602. Further, a second limiting position 402 is provided on the side wall of the outer mounting cavity 601, and the inner outlet water seat 10 abuts against the second limiting position 402. The gap between the inner outlet water seat 10 and the outlet water surface 602 constitutes the second flow passage 302.

[0055] In this embodiment, the outer water seat 60 is provided with an air inlet channel 604 that connects to the atmospheric environment and the second flow cavity 302. Specifically, the outer water seat 60 includes an outer seat 701 and an inner seat 702 disposed within the outer seat 701. The gap between the inner seat 702 and the outer seat 701 forms the air inlet channel 604. Ribs 80 are provided at a portion of the air inlet channel 604. The inner seat 702 is connected to the outer seat 701 through the ribs 80, and the upper end face of the ribs 80 protrudes from the edge of the inner seat 702. The upper end face of the ribs 80 forms a second limiting position 402. The outer side of the outer seat 701 is provided with threads for easy connection to the water outlet of an existing faucet.

[0056] The incoming water flows out after passing through the first flow chamber 301 and the second flow chamber 302 in sequence. When it flows through the second flow chamber 302, due to the Venturi effect, a negative pressure is generated in the second flow chamber 302. Outside air enters the second flow chamber 302 through the air intake channel 604 and mixes with the incoming water to form foaming water.

[0057] In this embodiment, the inner mounting cavity 101 is also provided with a filter screen 90, and the filter screen 90 and the deformation plate are arranged sequentially along the water outlet direction; it also includes a pressure ring 100 to press the filter screen 90 and the deformation plate into the inner mounting cavity 101.

[0058] Example 4

[0059] The following is combined with Figures 14-16 This utility model will be described in detail.

[0060] The difference from Embodiment 3 is that the external mounting cavity 601 is equipped with a constant flow device as described in Embodiment 2, the external water surface 602 is equipped with a drain outlet for water spraying from the first flow channel 2071, and the second flow channel 2072 is connected to the second flow cavity 302. The foaming principle of the second flow cavity 302 is as described in Embodiment 3. Thus, by controlling the opening and closing of the first flow channel 2071 and the second flow channel 2072, the water flow pattern of the water outlet device can be controlled to meet the diverse usage needs of customers.

[0061] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
