Description

Technical Field

[0001] This invention relates to the field of shower product technology, and in particular to a slow-release mechanism and slow-release device. Background Technology

[0002] As people's living standards improve, they have higher requirements for bathroom products, leading to the automatic addition of additives to these products to achieve better bathroom effects. Taking showerheads as an example, additives include vitamin C, essential oils, and bath water, which are automatically added to the showerhead's water supply pipes via an automatic supply device to meet people's needs for automatic bathing, skin care, and other aspects.

[0003] In the prior art, such as Chinese invention patent with publication number CN219033414U, an intelligent shower device is disclosed, including a water storage box, a mixing chamber, and a water pressure unit (pump). The water storage box is used to store different additives. The mixing box is connected to the water path of the shower head. The water pressure unit connects the water storage box and the mixing chamber. The control system is connected to the water pressure unit. The water pressure unit is used to pump the additives inside the water storage box into the interior of the mixing chamber. After the additives are mixed with water in the mixing chamber, they enter the water path of the shower head and are finally sprayed out by the shower head for the user to use for showering.

[0004] The existing solutions require a dedicated pump for power and a dedicated control system to operate the pump. They cannot automatically release additives as the water flows through the showerhead. They also require many components, are bulky, and are costly. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a slow-release mechanism and device. When water flows through the transfer pipe, the water flow mainly targets the outer convex corner side, while the water flow on the inner concave corner side is relatively less. Therefore, the water pressure at the inlet is lower than the water pressure at the outlet, creating a pressure difference between the inlet and outlet. The solution in the container enters the outlet pipe through the drain channel and inlet, and then is discharged. Water from the outer convex corner side replenishes the container through the outlet and inlet channel, achieving the function of automatically releasing the additive as the water flows through the water supply pipeline. This method requires fewer components, is small in size, and has low cost.

[0006] The present invention provides a slow-release mechanism, including a container for holding an additive, an adapter connected to the container, and an adapter pipe for connecting in series in a water supply pipeline.

[0007] The adapter includes an inlet channel and a drain channel that communicate with the container;

[0008] The adapter pipe includes an inlet pipe and an outlet pipe connected to the inlet pipe. The outlet pipe extends obliquely toward one side of the inlet pipe, and the angle between the outlet pipe and the inlet pipe is an obtuse angle. The area where the inner wall of the outlet pipe meets the inner wall of the inlet pipe forms a concave angle, and the area where the outer wall of the outlet pipe meets the outer wall of the inlet pipe forms a convex angle.

[0009] The inner wall of the outlet pipe is provided with an inlet hole at the end where it connects to the inlet pipe, and the outer wall of the inlet pipe is provided with an outlet hole at the end where it connects to the outlet pipe.

[0010] The water inlet channel is connected to the water outlet, and the water outlet channel is connected to the water inlet.

[0011] In one of the alternative technical solutions, the end of the inner wall of the water inlet pipe that connects with the inner wall of the water outlet pipe has a water-blocking protrusion, and the water inlet hole is located downstream of the water-blocking protrusion.

[0012] In one of the alternative technical solutions, the water inlet channel and the water outlet are connected by a first flexible hose, and the drainage channel and the water inlet are connected by a second flexible hose.

[0013] In one of the alternative technical solutions, a first connector communicating with the water outlet is provided on the wall of the water inlet pipe, and the first flexible hose is connected to the first connector;

[0014] The inner wall of the outlet pipe is provided with a second connector that communicates with the inlet hole, and the second hose is connected to the second connector.

[0015] In one of the alternative technical solutions, the adapter includes an adapter sleeve having the water inlet channel and the drain channel, and an adapter end cap connected to one end of the adapter sleeve.

[0016] The container has a container plug for insertion into the adapter sleeve, the container plug including a first channel and a second channel communicating with the container;

[0017] The adapter sleeve is fitted onto the container plug, the water inlet channel is connected to the first channel, and the drain channel is connected to the second channel.

[0018] In one of the alternative technical solutions, the water outlet of the first channel is inserted into the container, and the water outlet of the first channel is spaced at a predetermined distance from the liquid inlet of the second channel.

[0019] In one of the alternative technical solutions, a one-way valve for controlling the opening and closing of the first channel and the water inlet channel is installed in the adapter sleeve;

[0020] When the adapter sleeve and the container plug are in the assembled state, the one-way valve is in the open state, and the first channel and the water inlet channel are in the conductive state.

[0021] When the adapter sleeve and the container plug are detached, the one-way valve is separated from the first channel and the one-way valve is closed.

[0022] In one of the alternative technical solutions, the side of the first channel at the end where it is assembled with the one-way valve has a channel through hole;

[0023] The one-way valve includes a valve seat fixedly installed in the adapter sleeve, a valve core slidably assembled in the adapter sleeve, and an elastic drive member for driving the valve core to move toward the valve seat side.

[0024] When the adapter sleeve and the container plug are in the assembled state, the end of the first channel that is assembled with the one-way valve passes through the valve seat and pushes up the valve core, and the water inlet channel and the channel through hole are in the conductive state.

[0025] When the adapter sleeve and the container plug are detached, the valve core and the valve seat are in a sealing fit.

[0026] The present invention also provides a slow-release device, comprising a housing, a water circuit control valve, and the slow-release mechanism described in any of the foregoing technical solutions;

[0027] The housing has a housing inlet and a housing outlet, and the water circuit control valve is installed in the housing and communicates with the housing inlet;

[0028] The container is connected to the shell, the adapter pipe is installed in the shell, the water inlet pipe is connected to the control valve outlet of the water circuit control valve, and the water outlet pipe is connected to the water outlet of the shell.

[0029] In one alternative embodiment, the housing has a receiving cylinder, and the container is arranged within the receiving cylinder.

[0030] The above technical solution has the following beneficial effects:

[0031] The slow-release mechanism and device provided by this invention have a connecting pipe arranged in a corner configuration. The water inlet is located on the inner wall of the corner; specifically, the water inlet is located on the inner wall of the outlet pipe at the end where it connects to the water inlet pipe. The water outlet is located on the outer wall of the corner; specifically, the water outlet is located on the outer wall of the inlet pipe at the end where it connects to the outlet pipe.

[0032] As water flows from the inlet pipe to the outlet pipe in the water supply pipeline, the water flow mainly rushes towards the outward convex corner side and turns under the action of the outer pipe wall of the outlet pipe. The water flow on the inward concave corner side is relatively less. Therefore, the water pressure at the inlet is lower than the water pressure at the outlet, creating a pressure difference between the inlet and outlet. The additive mixture in the container automatically enters the outlet pipe through the drain channel and inlet, and then flows through the water supply pipeline to the bathroom product terminal (e.g., shower head) to meet the user's needs for automatic bathing, skin care, and other functions.

[0033] Water from the convex corner side is replenished into the container through the water outlet and water inlet channel, achieving automatic water replenishment.

[0034] In summary, the slow-release mechanism and device provided by this invention realize the function of automatically releasing additives as the water flows through the water supply pipeline. It requires fewer components, is small in size, and has low cost. Attached Figure Description

[0045] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0046] like Figure 1-6 As shown, an embodiment of the present invention provides a slow-release mechanism, including a container 1 for holding an additive, an adapter 2 connected to the container 1, and an adapter pipe 3 for connecting in series in a water supply pipeline.

[0047] The adapter 2 includes an inlet channel 23 and a drain channel 24 that are connected to the container 1.

[0048] The transfer pipe 3 includes an inlet pipe 31 and an outlet pipe 32 connected to the inlet pipe 31. The outlet pipe 32 extends obliquely toward the side of the inlet pipe 31. The angle between the outlet pipe 32 and the inlet pipe 31 is an obtuse angle. The area where the inner wall 321 of the outlet pipe 32 meets the inner wall 311 of the inlet pipe 31 forms a concave angle 33. The area where the outer wall 322 of the outlet pipe 32 meets the outer wall 312 of the inlet pipe 31 forms a convex angle 34.

[0049] The inner wall 321 of the outlet pipe 32 is provided with an inlet hole 323 at the end connected to the inlet pipe 31, and the outer wall 312 of the inlet pipe 31 is provided with an outlet hole 313 at the end connected to the outlet pipe 32.

[0050] The water inlet channel 23 is connected to the water outlet 313, and the drainage channel 24 is connected to the water inlet 323.

[0051] The slow-release mechanism provided by this invention is used to install on the water circuit of bathroom products to slowly release the additive in container 1 for user use. The bathroom product can be a shower head, etc., and the additive can be vitamin C, essential oil, or shower gel.

[0052] In this invention, the upstream or upstream side and the downstream or downstream side are defined by the direction of water flow. For example, the side of a component facing the direction of incoming water is the upstream side, and the side facing the direction of outgoing water is the downstream side.

[0053] The slow-release mechanism includes a container 1, an adapter 2, and an adapter pipe 3. The container 1 has a liquid-containing chamber for holding the additive. The adapter 2 is connected to the container 1 to achieve pipeline transfer. Preferably, the adapter 2 is detachably connected to the container 1. The adapter 2 has a water inlet channel 23 and a water outlet channel 24, which are respectively connected to the liquid-containing chamber of the container 1. The water inlet channel 23 is used to replenish water into the container 1, and the water outlet channel 24 is used to slowly discharge the additive mixture from the container 1.

[0054] The adapter pipe 3 is used in series in the water supply pipeline of the bathroom product. The adapter pipe 3 includes an inlet pipe 31 and an outlet pipe 32. The outlet pipe 32 is connected to one end of the inlet pipe 31, and in the direction of water flow in the water supply pipeline of the bathroom product, the inlet pipe 31 is upstream of the outlet pipe 32. The outlet pipe 32 and the inlet pipe 31 are connected by an angle or bend. Specifically, the outlet pipe 32 extends obliquely from the outlet end of the inlet pipe 31 towards one side of the inlet pipe 31, and the angle between the outlet pipe 32 and the inlet pipe 31 is an obtuse angle to avoid excessive bends that may affect water flow. Preferably, the angle between the outlet pipe 32 and the inlet pipe 31 is between 110° and 160°.

[0055] Therefore, the connection between the outlet pipe 32 and the inlet pipe 31 will form a concave angle and a convex angle. Because the concave angle is recessed towards the connection between the outlet pipe 32 and the inlet pipe 31, this concave angle is called an inner concave angle 33. Because the convex angle is convex outwards towards the connection between the outlet pipe 32 and the inlet pipe 31, this convex angle is called an outer convex angle 34. Correspondingly, the pipe walls of the outlet pipe 32 and the inlet pipe 31 are divided into inner pipe walls and outer pipe walls by the plane containing their respective axes. The inner concave angle 33 is formed in the area where the inner pipe wall 321 of the outlet pipe 32 meets the inner pipe wall 311 of the inlet pipe 31, and the outer convex angle 34 is formed in the area where the outer pipe wall 322 of the outlet pipe 32 meets the outer pipe wall 312 of the inlet pipe 31.

[0056] A water inlet hole 323 is provided at the end of the inner wall 321 of the outlet pipe 32 where it connects to the inlet pipe 31. That is, the water inlet hole 323 is located on the pipe wall at the concave angle 33, specifically at the end where the inner wall 321 of the outlet pipe 32 connects to the inner wall 311 of the inlet pipe 31. Preferably, the water inlet hole 323 is located in the middle of the inner wall 321 of the outlet pipe 32.

[0057] A water outlet 313 is provided at the end of the outer wall 312 of the inlet pipe 31 where it connects to the outlet pipe 32. That is, the water outlet 313 is located on the pipe wall of the outward convex angle 34, specifically at the end where the outer wall 312 of the inlet pipe 31 connects to the outer wall 322 of the outlet pipe 32. Preferably, the water outlet 313 is located in the middle of the outer wall 312 of the inlet pipe 31.

[0058] The water inlet channel 23 is connected to the water outlet 313. Specifically, the two can be directly connected or connected through a water pipe, connector, etc. The drainage channel 24 is connected to the water inlet 323. Specifically, the two can be directly connected or connected through a water pipe, connector, etc.

[0059] When supplying water through water supply pipes, such as Figure 6As shown, water flows from arrow A to arrow B. When water flows from inlet pipe 31 to outlet pipe 32, the water flow mainly rushes towards the outward convex angle 34 and turns under the action of the outer wall 322 of outlet pipe 32. The water flow on the inward concave angle 33 side is relatively less. Therefore, the water pressure at inlet hole 323 is lower than the water pressure at outlet hole 313, creating a pressure difference between outlet hole 313 and inlet hole 323. The additive mixture in container 1 automatically enters outlet pipe 32 through drainage channel 24 and inlet hole 323, and then flows through water supply pipe to the bathroom product terminal (e.g., shower head) to meet the user's needs for automatic bathing, skin care, and other functions.

[0060] Water from the outer convex angle 34 is replenished into container 1 through water outlet 313 and water inlet channel 23, achieving automatic water replenishment.

[0061] If the water outlet 313 is located on the outer wall 322 of the water outlet pipe 32, the water outlet 313 is very susceptible to water flow impact, the water pressure changes greatly, the pressure difference with the water inlet 323 is also large, and the pressure difference fluctuates, which is not conducive to the slow and uniform release of additives by the container 1.

[0062] The water outlet 313 is located on the outer wall 312 of the water inlet pipe 31. The water flows quickly along the outer wall 312 without impacting the water outlet 313. This helps to maintain the water pressure of the water outlet 313 and the pressure difference between the water outlet 313 and the water inlet 323, which is conducive to the slow and uniform release of additives by the container 1.

[0063] In summary, the slow-release mechanism and device provided by this invention realize the function of automatically releasing additives as the water flows through the water supply pipeline. It requires fewer components, is small in size, and has low cost.

[0064] Each time a user uses a bathroom product, the additive in container 1 is diluted once. After a period of time, the user can simply replenish the additive in container 1.

[0065] In actual use, container 1 can be placed horizontally, tilted, or vertically, and can be adjusted according to actual needs.

[0066] In one embodiment, such as Figure 5 As shown, the inner wall 311 of the inlet pipe 31 and the inner wall 321 of the outlet pipe 32 have a water-blocking protrusion 314 at one end, and the inlet hole 323 is located downstream of the water-blocking protrusion 314.

[0067] In this embodiment, a water-blocking protrusion 314 is provided on the inner wall 311 of the inlet pipe 31, protruding towards the inlet pipe 31 or the outlet pipe 32. The water-blocking protrusion 314 is located at the end where the inner wall 311 of the inlet pipe 31 connects to the inner wall 321 of the outlet pipe 32. The water inlet hole 323 is located at the end where the inner wall 321 of the outlet pipe 32 connects to the inner wall 311 of the inlet pipe 31. Therefore, the water inlet hole 323 is located downstream of the water-blocking protrusion 314, which acts as a water-blocking element and creates a siphon effect at the water inlet hole 323, forming a negative pressure that facilitates the smooth flow of water into the outlet pipe 32.

[0068] In one embodiment, such as Figure 1 As shown, the water inlet channel 23 and the water outlet 313 are connected by a first flexible hose 4, and the drain channel 24 and the water inlet 323 are connected by a second flexible hose 5.

[0069] In this embodiment, the adapter 2 and the adapter pipe 3 are connected by using the first hose 4 and the second hose 5, so that the container 1 and the adapter pipe 3 can be arranged separately in their respective positions to meet different installation requirements.

[0070] In one embodiment, such as Figure 1 and Figure 5 As shown, the inlet pipe 31 has a first connector 35 that communicates with the outlet hole 313 on its pipe wall, and the first hose 4 is connected to the first connector 35.

[0071] The inner wall of the outlet pipe 32 is provided with a second connector 36 that communicates with the inlet hole 323, and the second hose 5 is connected to the second connector 36.

[0072] In this embodiment, corresponding first connector 35 and second connector 36 are configured, and threaded or concave-convex structures are configured on the connectors to connect with the first hose 4 and the second hose 5.

[0073] In one embodiment, such as Figure 2-3 As shown, the adapter 2 includes an adapter sleeve 21 with a water inlet channel 23 and a drain channel 24, and an adapter end cap 22 connected to one end of the adapter sleeve 21.

[0074] The container 1 has a container plug 11 for insertion into the adapter sleeve 21. The container plug 11 includes a first channel 111 and a second channel 112 communicating with the container 1.

[0075] The adapter sleeve 21 is fitted onto the container plug 11. The water inlet channel 23 is connected to the first channel 111, and the drain channel 24 is connected to the second channel 112.

[0076] In this embodiment, the adapter 2 includes an adapter sleeve 21 and an adapter end cap 22. A water inlet channel 23 and a drainage channel 24 are disposed in the sleeve wall and / or connector of the adapter sleeve 21. The adapter end cap 22 seals one end of the adapter sleeve 21.

[0077] The container 1 has a container plug 11 for connecting to the adapter sleeve 21. The container plug 11 has a first channel 111 and a second channel 112 that are independent of each other, and the first channel 111 and the second channel 112 are respectively connected to the solution chamber of the container 1.

[0078] During installation, the adapter sleeve 21 is fitted onto the container plug 11, and the two are sealed by a sealing ring. The water inlet channel 23 is connected to the first channel 111, and the drain channel 24 is connected to the second channel 112. Specifically, the water inlet channel 23 can be directly connected to the first channel 111, or it can be transitioned through the cavity in the adapter sleeve 21; the drain channel 24 can be directly connected to the second channel 112, or it can be transitioned through the cavity in the adapter sleeve 21.

[0079] When it is necessary to replace container 1 or to add additives to container 1, remove the adapter sleeve 21 from the container plug 11, separate the water inlet channel 23 from the first channel 111, and separate the drain channel 24 from the second channel 112. Then place the new container 1 or the container 1 with added additives in place, and put the adapter sleeve 21 onto the container plug 11. The operation is convenient.

[0080] In one embodiment, such as Figure 2-3 As shown, the adapter sleeve 21 is provided with a third connector 25 and a fourth connector 26. The water inlet channel 23 passes through the third connector 25 or is the center hole of the third connector 25, and the drain channel 24 passes through the fourth connector 26 or is the center hole of the fourth connector 26.

[0081] The third connector 25 and the fourth connector 26 are provided with threaded or convex / concave structures for connection with the first hose 4 and the second hose 5.

[0082] In one embodiment, such as Figure 2-3 As shown, the water outlet 1111 of the first channel 111 is inserted into the container 1. The water outlet 1111 of the first channel 111 is spaced at a predetermined distance from the liquid inlet 1121 of the second channel 112.

[0083] In this embodiment, the length of the water outlet 1111 of the first channel 111 extending into the container 1 is greater than the length of the liquid inlet 1121 of the second channel 112.

[0084] When water is added to container 1, the water enters the additive mixture in container 1 directly. The water outlet 1111 of the first channel 111 is a distance away from the liquid inlet 1121 of the second channel 112 to avoid diluting the concentration of the additive mixture in the liquid inlet 1121 with the added water.

[0085] In one embodiment, such as Figure 2-4 As shown, a one-way valve 27 for controlling the opening and closing of the first channel 111 and the water inlet channel 23 is installed in the adapter sleeve 21.

[0086] When the adapter sleeve 21 and the container plug 11 are in the assembled state, the one-way valve 27 is in the open state, and the first channel 111 and the water inlet channel 23 are in the conductive state.

[0087] When the adapter sleeve 21 and the container plug 11 are in a disassembled state, the one-way valve 27 is separated from the first channel 111 and the one-way valve 27 is in a closed state.

[0088] In this embodiment, a one-way valve 27 is installed in the adapter sleeve 21, which is used to control the opening and closing of the first channel 111 and the water inlet channel 23. Under normal conditions, the first channel 111 and the water inlet channel 23 are in a conductive state, and water can be replenished into the container 1 normally. When the adapter sleeve 21 is removed from the container plug 11 to replace the container 1, the one-way valve 27 is separated from the first channel 111 and is in a closed state, preventing the water inlet channel 23 from continuing to replenish water and affecting the replacement of the container 1.

[0089] The one-way valve 27 can be a mechanical valve with an operating handle. When it is necessary to replace the container 1, the user operates the handle to close the one-way valve 27. After the adapter 2 is assembled with the container 1, the user operates the handle to open the one-way valve 27.

[0090] In one embodiment, such as Figure 3-4 As shown, the side of the first channel 111 that is assembled with the one-way valve 27 has a channel through hole 113.

[0091] The one-way valve 27 includes a valve seat 271 fixedly mounted in the adapter sleeve 21, a valve core 272 slidably mounted in the adapter sleeve 21, and an elastic drive member 273 for driving the valve core 272 to move toward the valve seat 271.

[0092] When the adapter sleeve 21 and the container plug 11 are in the assembled state, the end of the first channel 111 that is assembled with the one-way valve 27 passes through the valve seat 271 and pushes up the valve core 272, and the water inlet channel 23 and the channel through hole 113 are in the conductive state.

[0093] When the adapter sleeve 21 and the container plug 11 are in the disassembled state, the valve core 272 and the valve seat 271 are in a sealing fit.

[0094] In this embodiment, the one-way valve 27 can automatically open and close according to the engagement and disengagement status of the adapter sleeve 21 and the container plug 11.

[0095] The side of the first channel 111, which is assembled with the one-way valve 27, has a channel hole 113 for water passage.

[0096] A transition water cavity 28 is formed between the adapter sleeve 21, the container plug 11, and the adapter end cap 22. The water inlet channel 23 communicates with the transition water cavity 28.

[0097] The one-way valve 27 includes a valve seat 271, a valve core 272, and an elastic actuator 273. The valve seat 271 is fixedly installed in the adapter sleeve 21. Preferably, the valve seat 271 is located in the transition water chamber 28 near one end of the container 1 and is sealed.

[0098] The valve core 272 is slidably mounted in the transition water cavity 28 of the adapter sleeve 21. If necessary, a guide bracket 29 can be configured in the transition water cavity 28, and the guide rod of the valve core 272 is slidably connected to the guide bracket 29.

[0099] The elastic drive 273 is installed in the transition water chamber 28, with one end connected to the valve core 272. It is used to drive the valve core 272 to move toward the valve seat 271 so that the valve core 272 can fall on the valve seat 271, thereby closing the one-way valve 27.

[0100] When assembling the adapter 2 with the container plug 11, the end of the first channel 111 that is assembled with the one-way valve 27 passes through the valve seat 271 and pushes up the valve core 272. The channel through hole 113 is in the transition water chamber 28, and the water inlet channel 23 is in a conductive state with the channel through hole 113. Under normal conditions, the end of the first channel 111 pushes against the valve core 272, and the elastic drive member 273 is in a compressed state.

[0101] When the adapter 2 is removed from the container plug 11, the first channel 111 separates from the valve core 272. Under the action of the elastic drive member 273, the valve core 272 falls on the valve seat 271 and seals, thereby closing the one-way valve 27. Water in the transition water chamber 28 will not flow out from the one-way valve 27.

[0102] like Figure 7-9 As shown, an embodiment of the present invention provides a slow-release device, including a housing 6, a water circuit control valve 7, and the slow-release mechanism described in any of the preceding embodiments.

[0103] The housing 6 has a housing inlet and a housing outlet 61, and a water control valve 7 is installed in the housing 6 and connected to the housing inlet.

[0104] Container 1 is connected to shell 6, adapter pipe 3 is installed in shell 6, inlet pipe 31 is connected to the control valve outlet of water circuit control valve 7, and outlet pipe 32 is connected to the outlet 61 of shell.

[0105] The slow-release device provided by this invention is a control mechanism part of the water supply pipeline of a bathroom product, which includes a housing 6, a water control valve 7, and a slow-release mechanism. For the structure, construction, and working principle of the slow-release mechanism, please refer to the previous description of the slow-release mechanism, which will not be repeated here.
