Description

Technical Field

[0001] The present invention relates to the technical field of bathrooms, and in particular to a shower head. Background Art

[0002] The water outlets of existing shower heads with fine water outlet function are generally small and dense, so that the water flow sprayed from the water outlet is fine and dense. However, since the water outlet is very small, scale in tap water is easy to accumulate at the water outlet after long-term use and block the water outlet, causing problems such as oblique water flow and reduced water output.

[0003] The existing descaling method usually uses a descaling needle plate for descaling, which is relatively costly. Summary of the invention

[0004] The technical problem to be solved by the present application is how to remove dirt at the water outlet.

[0005] An embodiment of the present invention provides a shower head, which includes: Water inlet parts, including water inlet channels; The faucet part comprises an elastic faucet sleeve, on which a water outlet is arranged; A flow channel member, comprising a water delivery portion inserted into the water nozzle sleeve, wherein the water delivery portion is provided with a descaling flow channel connected to the water outlet; and The pulse component is arranged between the water inlet flow channel and the descaling flow channel, and is used for converting the water flow transported from the water inlet flow channel to the descaling flow channel into a pulse water flow.

[0006] In the first descaling water outlet position, after the descaling channel is connected to the water inlet channel through the pulse component, the water flows through the water inlet channel, the pulse component, and the descaling channel in sequence to reach the water outlet, and then is output from the water outlet. Since the pulse component converts the water flow into a pulse water flow, and the nozzle sleeve is elastic, the pulse water flow will intermittently impact the nozzle sleeve after being delivered to the nozzle sleeve, causing the water pressure in the nozzle sleeve to alternate between high water pressure and low water pressure. When the water pressure in the nozzle sleeve is high, the water outlet of the nozzle sleeve swells. At the same time, due to the deformation of the nozzle sleeve, the structure of the scale attached to the nozzle sleeve becomes loose as the nozzle sleeve is deformed, and it is easy to be washed away by water. When the water pressure in the nozzle sleeve is low, the water outlet of the nozzle sleeve shrinks. The water outlet alternates between expansion and contraction, and the scale cannot alternately increase or decrease with the water outlet, and the scale is more likely to fall off. In particular, the pulse water flow intermittently impacts the scale on the water outlet, which can peel off and wash away the loose scale from the water outlet, so that the water can flush the dirt blocking the water outlet out of the water outlet. At the same time, after the descaling flow channel is connected to the water inlet flow channel through the pulse component, a pulse water flow is sprayed out from the water outlet, which can intermittently impact the user's body, thereby playing a massage role. Therefore, it can also be used as a new type of massage water splash.

[0007] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the description and the drawings.

DETAILED DESCRIPTION

[0010] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0011] like Figure 1 , 2 As shown, Figure 1 , 2 The structure of a shower head 100 in an embodiment of the present application is shown. The shower head 100 comprises a water inlet component 2, a faucet component 5, a flow channel component 4, a pulse component 1a and a housing 1.

[0012] The housing 1 includes a handle 11 and a mounting shell 12. One end of the handle 11 is connected to the mounting shell 12. A mounting channel is provided in the handle 11, extending from one end facing away from the mounting shell 12 to one end close to the mounting shell 12. A mounting cavity is provided in the mounting shell 12, and one end of the mounting channel is connected to the mounting cavity. The mounting shell 12 can be constructed as a flat cylindrical cavity. An opening is provided on the wall of the mounting cavity, and the opening can be a circular opening provided at one end of the mounting shell 12.

[0013] The water inlet 2 is constructed as a cylindrical structure. A water inlet channel 20 is provided in the water inlet 2. The water inlet channel extends from one end of the water inlet 2 to the other end of the water inlet 2. The water inlet 2 extends into the installation channel from the end of the installation channel of the handle 11 facing away from the installation shell 12, and the water inlet 2 extends along the installation channel. The end of the water inlet 2 facing away from the installation shell 12 may extend out of the installation channel. The end of the water inlet 2 facing away from the installation shell 12 may be provided with an external thread for externally connecting a water supply pipe, and the water supply pipe injects water into the water inlet channel 20 of the water inlet 2.

[0014] like Figure 2 , 4As shown, the faucet member 5 is arranged in the installation cavity of the installation shell 12. The faucet member 5 is elastic and can be elastically deformed. The faucet member 5 is made of an elastic material, such as silicone or rubber. The faucet member 5 includes a faucet sleeve 51. The faucet sleeve 51 is constructed as a sleeve structure or a barrel structure. A water outlet 510 is arranged on the faucet sleeve 51. The water outlet 510 is a through hole. There may be a plurality of water outlets 510. The faucet sleeve 51 of the faucet member 5 may extend toward the opening of the installation shell 12.

[0015] like Figure 3 , 4 As shown, the flow channel member 4 is arranged in the installation cavity of the installation shell 12. The flow channel member 4 can be made of metal or plastic. The flow channel member 4 is arranged on the side of the opening of the faucet member 5 facing away from the installation shell 12. The flow channel member 4 includes a water delivery portion 42. Figure 5 , 6 As shown, the water delivery part 42 can be constructed as a cylindrical structure, and the water delivery part 42 is inserted into the water nozzle sleeve 51. A descaling flow channel 43 is provided on the water delivery part 42. One end of the descaling flow channel 43 extends into the water nozzle sleeve 51 and is connected to the water outlet 510 on the water nozzle sleeve 51, and the other end of the descaling flow channel 43 is connected to the pulse component 1a.

[0016] The pulse assembly 1a is connected to the flow channel member 4. The pulse assembly 1a is arranged between the water inlet flow channel 20 of the water inlet member 2 and the descaling flow channel 43 of the flow channel member 4. When the water inlet flow channel 20 conveys water to the descaling flow channel 43, it needs to flow through the pulse assembly 1a first. The pulse assembly 1a is configured to convert the water flow conveyed from the water inlet flow channel 20 to the descaling flow channel 43 into a pulse water flow, and convey the pulse water flow to the descaling flow channel 43.

[0017] In this way, after the descaling channel 43 is connected to the water inlet channel 20 through the pulse component 1a, the water flows through the water inlet channel 20, the pulse component 1a, and the descaling channel 43 in sequence to reach the water outlet 510, and then is output from the outlet 510. Since the pulse component 1a converts the water flow into a pulse water flow, and the nozzle cover 51 has elasticity, the pulse water flow will intermittently impact the nozzle cover 51 after being transported into the nozzle cover 51, so that the water pressure in the nozzle cover 51 alternates between high water pressure and low water pressure. When the water pressure in the nozzle cover 51 is high, the water outlet 510 of the nozzle cover 51 swells. At the same time, due to the deformation of the nozzle cover 51, the structure of the scale attached to the nozzle cover 51 becomes loose with the deformation of the nozzle cover 51. The scale on the water outlet 510 can be easily washed away by water, and when the water pressure in the water outlet sleeve 51 is low, the water outlet 510 of the water outlet sleeve 51 shrinks, and the water outlet 510 changes alternately between expansion and contraction. The scale cannot follow the water outlet 510 to alternately expand and shrink, and the scale is easier to fall off. In particular, the pulse water flow intermittently impacts the scale on the water outlet 510, which can peel off and flush away the loose scale from the water outlet 510, so that the water can flush the scale blocking the water outlet 510 out of the water outlet 510. At the same time, after the descaling flow channel 43 is connected to the water inlet flow channel 20 through the pulse component 1a, the pulse water flow sprayed from the water outlet 510 can intermittently impact the user's body, thereby playing a massage role, and thus, it can also be used as a new type of massage water spray.

[0018] In an illustrative embodiment, Figure 4 , 15 As shown, the pulse assembly 1a includes a first rotor 11a. The first rotor 11a may be rotatably connected to the flow channel member 4. The first rotor 11a may freely rotate around a first rotation axis, and the first rotation axis may coincide with the central axis of the first rotor 11a.

[0019] The first rotor 11a includes a shielding portion 113a. The shielding portion 113a is arranged on one side of the rotation axis of the first rotor 11a. The shielding portion 113a can make a circular motion when the first rotor 11a rotates. The shielding portion 113a abuts against the flow channel member 4. The shielding portion 113a can slide along the surface of the flow channel member 4 when making a circular motion. An inlet is provided at one end of the descaling flow channel 43, and an outlet is provided at the other end. The inlet of the descaling flow channel 43 is connected to the pulse component 1a, and the outlet of the descaling flow channel 43 is connected to the water outlet 510 on the nozzle sleeve 51. The outlet of the descaling flow channel 43 faces the water outlet 510, and the inlet of the descaling flow channel 43 is located on one side of the movement trajectory of the shielding portion 113a.

[0020] Every time the shielding part 113a rotates one circle, the entrance of the descaling channel 43 is closed and opened once. When the shielding part 113a continues to rotate, the entrance of the descaling channel 43 can be alternately opened and closed by the shielding part 113a, so that water flows intermittently from the entrance of the descaling channel 43 into the descaling channel 43 to form a pulse water flow.

[0021] In an illustrative embodiment, Figure 6 As shown, a thin water outlet channel 44 is provided on the water delivery part 42. One end of the thin water outlet channel 44 extends into the nozzle sleeve 51 and is connected to the water outlet 510 on the nozzle sleeve 51. The diameter of the descaling channel 43 is larger than the diameter of the thin water outlet channel 44. The extension directions of the descaling channel 43 and the thin water outlet channel 44 are both parallel to the axial direction of the water delivery part 42. The descaling channel 43 can be only one and is set in the middle of the water delivery part 42. The thin water outlet channel 44 can be set on the side wall of the delivery part 42. The positions of the descaling channel 43 and the thin water outlet channel 44 are not limited to this form.

[0022] The switching assembly 3 is arranged in the housing 1. The switching assembly 3 connects the faucet 5 and the water inlet 2. The switching assembly 3 is respectively connected to the water inlet channel 20, the thin water outlet channel 44 and the descaling channel 43. The pulse assembly 1a is arranged downstream of the switching assembly 3, and the switching assembly is connected to the descaling channel 43 through the pulse assembly 1a. The switching component 3 is configured to selectively connect the water inlet channel 20 to the thin water outlet channel 44, to connect the water inlet channel 20 to the descaling channel 43, and to connect the water inlet channel 20 to the thin water outlet channel 44 and the descaling channel 43, that is, the water inlet channel 20 can be connected to the thin water outlet channel 44 and the water inlet channel 20 can be disconnected from the descaling channel 43, the water inlet channel 20 can be connected to the descaling channel 43 and the water inlet channel 20 can be disconnected from the thin water outlet channel 44, and the water inlet channel 20 can be connected to the descaling channel 43 and the water inlet channel 20 can be disconnected from the thin water outlet channel 44, and the water inlet channel 20 can be connected to the descaling channel 43 and the thin water outlet channel 44 at the same time.

[0023] In this way, when the user uses the fine water outlet function of the shower head 100 for showering, the user operates the switching component 3 to connect the fine water outlet channel 44 with the water inlet channel 20, and the water flows through the water inlet channel 20 and the fine water outlet channel 44 in sequence to reach the water outlet 510, and is output from the water outlet 510. At this time, the shower head 100 can spray a fine fine water outlet flow. When the user finds that the water outlet 510 needs to be descaled, the user operates the switching component 3 to connect the descaling channel 43 with the water inlet channel 20, and the water flows through the water inlet channel 20, the pulse component 1a, and the descaling channel 43 in sequence to reach the water outlet 510. The pulse water flow output by the pulse component 1a can flush the dirt blocking the water outlet 510 out of the water outlet 510. After the descaling is completed, the user only needs to re-operate the switching component 3 to connect the fine water outlet channel 44 with the water inlet channel 20 to switch back to the fine water outlet function to shower with water.

[0024] like Fig.16 , 17As shown, when the water outlet 510 needs to be descaled, the user can also operate the switching component 3 to connect the descaling channel 43 and the thin water outlet channel 44 with the water inlet channel 20 at the same time. One water flow flows through the water inlet channel 20, the pulse component 1a, and the descaling channel 43 in sequence to reach the water outlet 510. At the same time, another water flow flows through the water inlet channel 20 and the thin water outlet channel 44 in sequence to reach the water outlet 510. The pulse water flow output by the pulse component 1a can impact the nozzle sleeve 51 to make the water outlet 510 alternately larger and smaller, thereby achieving the removal of dirt. At the same time, in the process of the water outlet 510 being pressurized and expanded and rebounding to become smaller, the thin water outlet channel 44 continues to supply water to the water outlet 510 to impact the water outlet 510, so that the dirt is quickly separated from the water outlet 510 and washed away by the water flow. This double descaling method has a stronger cleaning power.

[0025] In an exemplary embodiment, the shower head 100 further includes a switching assembly 3. The switching assembly 3 includes a water channel member 31. The water channel member 31 is connected to the flow channel member 4. The water channel member 31 and the flow channel member 4 enclose a descaling chamber 9a. The descaling chamber 9a may be a disc-shaped cavity. The first rotor 11a is disposed in the descaling chamber 9a. The first rotor 11a may be rotatably connected to the water channel member 31 and / or the flow channel member 4.

[0026] The inlet of the descaling flow channel 43 is arranged on a wall surface of the descaling chamber 9 a , and the wall surface is a side of the flow channel member 4 facing the water channel member 31 .

[0027] The water channel member 31 is provided with a descaling water inlet 31e. The water channel member 31 serves as another wall surface of the descaling chamber 9a, and the descaling water inlet 31e is provided on the wall surface. The descaling water inlet 31e of the water channel member 31 and the entrance of the descaling flow channel 43 are respectively provided on opposite sides of the descaling chamber 9a. The water inlet flow channel 20 can be connected to the descaling chamber 9a through the descaling water inlet 31e. The water flows through the water inlet flow channel 20, the descaling water inlet 31e, the descaling chamber 9a and the descaling flow channel 43 in sequence. When the descaling water inlet 31e injects water into the descaling chamber 9a, the descaling water inlet 31e is provided to discharge water obliquely in the rotation direction of the first rotor 11a.

[0028] Since the descaling water inlet 31e discharges water obliquely in the rotation direction of the first rotor 11a, the first rotor 11a is impacted by the water flow and hydraulic force and is subjected to a torque in the same direction as the rotation direction of the first rotor 11a, thereby driving the first rotor 11a to rotate.

[0029] In an illustrative embodiment, Fig.15 The flow channel member 4 is provided with a shaft portion 401 extending into the descaling chamber 9a. The shaft portion 401 of the descaling chamber 9a may be cylindrical. The shaft portion 401 extends to the flow channel member 4. The shaft portion 401 is arranged at the center of the descaling chamber 9a and is arranged coaxially with the descaling chamber 9a.

[0030] The first rotor 11a also includes a cylinder 111a and a plurality of water retaining strips 112a. The cylinder 111a can be constructed in a cylindrical shape. The cylinder 111a is sleeved on the rotating shaft portion 401. There is a clearance fit between the cylinder 111a and the rotating shaft portion 401. The cylinder 111a can rotate around the rotating shaft portion 401. The water retaining strip 112a is constructed in a straight strip shape. The opposite sides of the water retaining strip 112a can contact the opposite side walls of the descaling chamber 9a, that is, contact the water channel member 31 and the flow channel member 4 respectively. Multiple water retaining strips 112a extend from the outer peripheral surface of the cylinder 111a to the radially outward direction of the cylinder 111a. The multiple water retaining strips 112a are evenly distributed in the circumferential direction of the cylinder 111a. The length of the water retaining strip 112a is greater than the distance from the descaling water inlet 31e to the axis of the rotating shaft portion 401. The shielding portion 113a is connected to the water retaining bar 112a.

[0031] In this way, since the length of the water retaining bar 112a is greater than the distance from the descaling water inlet 31e to the axis of the rotating shaft portion 401, the water flow sprayed from the descaling water inlet 31e can directly impact the water retaining bar 112a, and the water retaining bar 112a can be driven by the water flow sprayed from the descaling water inlet 31e to drive the cylinder 111a and the shielding portion 113a to rotate synchronously. The structure of the first rotor 11a is simple and easy to manufacture.

[0032] In an illustrative embodiment, a plurality of descaling water inlets 31e are provided, and the plurality of descaling water inlets 31e are evenly distributed around the cylinder 111a.

[0033] In this way, multiple descaling water inlets 31e are evenly distributed on the circumference of the cylinder 111a and surround the cylinder 111a. Multiple descaling water inlets 31e simultaneously spray water in the rotation direction of the first rotor 11a. The impact force of the water flow on the first rotor 11a is greater, the first rotor 11a can rotate faster, the water pressure of the pulse water flow changes faster, and the descaling effect is better.

[0034] In an exemplary embodiment, the shielding portion 113a is configured as a fan-shaped flat plate. The fan-shaped flat plate is configured as a fan. The arc edge of the fan-shaped flat plate is coaxial with the cylinder 111a. One plate surface of the fan-shaped flat plate faces the water channel member 31, and the other plate surface faces the flow channel member 4. The plate surface of the fan-shaped flat plate facing the flow channel member 4 abuts against the flow channel member 4.

[0035] The shielding part 113a is constructed as a fan-shaped flat plate. Every time the shielding part 113a rotates one circle, the entrance of the descaling flow channel 43 is blocked by the shielding part 113a for a consistent time, the water output of these descaling flow channels 43 can be consistent, and the water output of the water outlet 510 is uniform.

[0036] In an illustrative embodiment, Fig.15As shown, the flow channel member 4 also includes a first plate body 41, a first circular ring 402, a second circular ring 403 and a third circular ring 404. The first plate body 41 can be constructed as a roughly circular flat plate. The first plate body 41 and the water channel member 31 enclose a descaling chamber 9a. A water inlet hole 410 is also provided on the first plate body 41. There are multiple water delivery parts 42, and the multiple water delivery parts 42 are all arranged on a plate surface of the first plate body 41 facing away from the water channel member 31. A water inlet hole 410 is also provided on the first plate body 41. The water inlet hole 410 is a through hole, and the water inlet hole 410 passes through the first plate body 41. The water inlet hole 410 can be a circular through hole.

[0037] The shaft portion 401, the first circular ring 402, the second circular ring 403 and the third circular ring 404 are all arranged on the plate surface of the first plate body 41 facing the water channel member 31. The first circular ring 402, the second circular ring 403 and the third circular ring 404 are all constructed as annular protrusions protruding from the plate surface of the first plate body 41. The diameters of the first circular ring 402, the second circular ring 403 and the third circular ring 404 increase successively. The diameter of the first circular ring 402 is greater than the diameter of the shaft portion 401. The shaft portion 401, the first circular ring 402, the second circular ring 403, the third circular ring 404 and the first plate body 41 are coaxially arranged. The ends of the first circular ring 402, the second circular ring 403 and the third circular ring 404 facing away from the first plate body 41 are all against the water channel member 31. The end of the water retaining strip 112a facing away from the cylinder body 111a is close to the first circular ring 402, and is in clearance fit with the first circular ring 402.

[0038] The shaft portion 401 is located inside the first circular ring 402, and the distance between the shaft portion 401 and the first circular ring 402 is uniform. The first circular ring 402 is located inside the second circular ring 403, and an annular channel 405 is formed between the first circular ring 402 and the second circular ring 403. The second circular ring 403 is arranged inside the third circular ring 404, and an annular slideway 406 is formed between the second circular ring 403 and the third circular ring 404.

[0039] The pulse assembly 1a further includes a second rotor 12a. The second rotor 12a is disposed in the annular slideway 406 and can slide along the annular slideway 406. The second rotor 12a can perform circular motion along the annular slideway 406.

[0040] Multiple descaling water inlets 31e are all connected to the internal space of the first circular ring 402. A first opening 4021 is provided on the first circular ring 402. The first opening 4021 can be configured as a through hole that radially penetrates the first circular ring 402. A plurality of first openings 4021 can be provided, and the plurality of first openings 4021 are evenly distributed in the circumferential direction of the first circular ring 402. A plurality of second openings 4031 are provided on the second circular ring 403, and the second openings 4031 can be configured as through holes whose extension direction is inclined to the radial direction of the annular slide 406. The extension directions of the plurality of second openings 4031 are inclined to the same circumferential direction of the annular slide 406, for example, the plurality of second openings 4031 are inclined to the clockwise direction or the counterclockwise direction of the annular slide 406. The plurality of second openings 4031 are configured to spray water into the annular slide 406 in the same circumferential direction of the annular slide 406.

[0041] There are multiple water delivery parts 42. The multiple water delivery parts 42 are all arranged on the side of the first plate body 41 facing away from the water channel member 31. The descaling flow channel 43 sequentially penetrates the water delivery part 42 and the first plate body 41 to connect the descaling cavity 9a with the water outlet 510. The entrances of the multiple descaling flow channels 43 are distributed in the first ring 402 and the annular slide 406.

[0042] A plurality of faucet sleeves 51 are provided, and a plurality of water delivery parts 42 extend into the plurality of faucet sleeves 51 respectively.

[0043] In this way, the descaling water inlet 31e injects water into the first circular ring 402 to drive the first rotor 11a to rotate, and the first rotor 11a can alternately open and close the entrance of the descaling flow channel 43 in the first circular ring 402. After the water enters the first circular ring 402, a part of the water flows through the first opening 4021, the annular channel 405 and the second opening 4031 in sequence into the annular slide 406, and then enters the descaling flow channel 43 from the annular slide 406. Since the multiple second openings 4031 spray water into the annular slide 406 obliquely in the same circumferential direction of the annular slide 406, the water flows in the annular slide 406 in the same circumferential direction of the annular slide 406, and these water flows can drive the second rotor 12a to slide along the annular slide 406. The second rotor 12a rotates one circle along the annular slide 406, and can open and close the entrance of the descaling flow channel 43 in the annular slide 406 once. When the second rotor 12a rotates continuously, the entrances of these descaling channels 43 can be opened and closed alternately, thereby forming a pulse water flow that is delivered to the descaling channels 43. The pulse water flow intermittently impacts the scale on the water outlet 510, and can peel off and flush away the loosened scale from the water outlet 510, so that the water can flush the scale that blocks the water outlet 510 out of the water outlet 510.

[0044] In an illustrative embodiment, Fig. 9 , 10As shown in Figures 1 and 11, the switching assembly 3 includes a water channel member 31 and a water sealing column 32. The water channel member 31 includes a body 311. The body 311 is the main part of the water channel member 31. The body 311 is provided with an installation cavity 31b, an inlet channel 31a, a thin outlet channel 31d and a descaling channel 31c. The inlet channel 31a, the thin outlet channel 31d and the descaling channel 31c converge at the installation cavity 31b. One end of the inlet channel 31a is connected to the installation cavity 31b, and the other end extends from the installation cavity 31b to the water inlet member 2 and is connected to the water inlet flow channel 20 of the water inlet member 2. One end of the thin outlet channel 31d is connected to the installation cavity 31b, and the other end is connected to the thin outlet flow channel 44 of the flow channel member 4. One end of the thin outlet channel 31d is connected to the installation cavity 31b, and the other end is connected to the descaling flow channel 43 of the flow channel member 4.

[0045] The water sealing column 32 includes a connecting portion 321 and a connecting portion 322. The connecting portion 322 is connected to the connecting portion 321. The connecting portion 321 is arranged in the installation cavity 31b. A connecting waterway 320 is arranged on the connecting portion 321. The connecting waterway 320 can be arranged as a through groove that penetrates the connecting portion 321. The connecting portion 322 is rotatably connected to the waterway member 31 so that the water sealing column 32 can rotate around the second rotation axis. In this embodiment, the extending direction of the connecting waterway 320 is perpendicular to the rotation axis, and one end of the water inlet waterway 31a, the fine water outlet waterway 31d and the descaling waterway 31c extends to the side wall of the installation cavity 31b.

[0046] The water sealing column 32 can be rotated to the fine water outlet position where the two ends of the connecting water channel 320 are respectively connected to the water inlet channel 31a and the fine water outlet channel 31d to connect the water inlet channel 31a only with the fine water outlet channel 31d. The water sealing column 32 can be rotated to the first descaling water outlet position where the two ends of the connecting water channel 320 are respectively connected to the water inlet channel 31a and the descaling water channel 31c to connect the water inlet channel 31a only with the descaling water channel 31c. The water sealing column 32 can also be rotated to the second descaling water outlet position where one end of the connecting water channel 320 is connected to the water inlet channel 31a, and the other end is connected to the descaling water channel 31c and the fine water outlet channel 31d to connect the water inlet channel 31a to both the descaling water channel 31c and the fine water outlet channel 31d.

[0047] In this way, the user rotates the water sealing column 32 to the fine water outlet position, and the water inlet channel 31a can be connected with the fine water outlet channel 31d, thereby realizing fine water outlet of the shower head 100; the user rotates the water sealing column 32 to the first descaling water outlet position or the second descaling water outlet position, and the water inlet channel 31a can be connected with the descaling water outlet 31c, thereby realizing descaling of the water outlet 510.

[0048] In an exemplary embodiment, the water inlet hole 410 is disposed at the bottom of the annular channel 405 .

[0049] The faucet member 5 further includes a second plate 52. The second plate 52 is constructed as a substantially flat plate. The second plate 52 covers the side of the first plate 41 facing away from the water channel member 31. A thin water outlet cavity 9b is enclosed between the second plate 52 and the first plate 41. The thin water outlet cavity 9b can be constructed as a gap between the first plate 41 and the second plate 52. One end of the thin water outlet channel 44 is connected to the water outlet 510 of the faucet sleeve 51, and the other end of the thin water outlet channel 44 is connected to the thin water outlet cavity 9b.

[0050] A thin water outlet and water inlet channel 31f is provided on the water channel member 31. The thin water outlet and water inlet channel 31f passes through the annular channel 405 and extends to the water inlet hole 410 to connect the thin water outlet cavity 9b with the thin water outlet channel.

[0051] The plurality of faucet sleeves 51 are all disposed on a side of the second plate body 52 facing away from the first plate body 41 , and the plurality of water delivery parts 42 pass through the second plate body 52 and extend into the plurality of faucet sleeves 51 respectively.

[0052] In this way, after the water sealing column 32 rotates to the thin water outlet position, water can flow through the water inlet channel 20 of the water inlet member 2, the water inlet channel 31a of the water channel member 31, the connecting water channel 320 of the water sealing column 32, the thin water outlet channel 31d of the water channel member 31, the thin water outlet and inlet channel 31f of the water channel member 31, the thin water outlet cavity 9b, the thin water outlet channel 44 of the flow channel member 4 and the water outlet 510 of the water nozzle member 5, and is output from the water outlet 510 of the plurality of water nozzle sleeves 51. At the same time, the thin water outlet and inlet channel 31f is arranged through the annular channel 405, which can prevent the water outlet and inlet channels from interfering with the rotation of the first rotor 11a and the second rotor 12a.

[0053] In an illustrative embodiment, the diameter of the descaling flow channel 43 is more than three times the diameter of the thin water outlet flow channel 44 .

[0054] The diameter of the descaling channel 43 is greater than or equal to 3 times the diameter of the fine water outlet channel 44. The diameter of the descaling channel 43 can be large enough, and the impact force generated by the water flow output by the descaling channel 43 is relatively large, which makes the deformation degree of the nozzle cover 51 larger. The structure of the scale attached to the nozzle cover 51 becomes looser as the deformation of the nozzle cover 51 increases, and it is easier to be washed away by water, so as to ensure that the dirt at the water outlet 510 is removed.

[0055] In an illustrative embodiment, Figure 6 As shown, the water outlet 510 is arranged on the bottom wall of the faucet cover 51. The water outlet 510 penetrates the bottom wall of the faucet cover 51.

[0056] The water delivery portion 42 is configured to be cylindrical. There is a gap between one end of the water delivery portion 42 facing the bottom wall of the faucet sleeve 51 and the bottom wall of the faucet sleeve 51. The water delivery portion 42 can be configured to be roughly cylindrical. The descaling flow channel 43 extends along the central axis of the water delivery portion 42. One end of the descaling flow channel 43 faces the bottom wall of the faucet sleeve 51. One end of the descaling flow channel 43 facing the bottom wall of the faucet sleeve 51 is an expansion opening 431. The closer the expansion opening 431 is to the bottom wall of the faucet sleeve 51, the larger its diameter. The expansion opening 431 can be configured to be an outwardly expanding conical opening.

[0057] Since there is a gap between one end of the water delivery portion 42 facing the bottom wall of the nozzle sleeve 51 and the bottom wall of the nozzle sleeve 51, and one end of the descaling channel 43 facing the bottom wall of the nozzle sleeve 51 is an expansion opening 431, a strong conical splashing water is formed when the water flows from the expansion opening 431 toward the bottom wall of the nozzle sleeve 51. The conical splashing water can form a strong impact on the bottom wall of the nozzle sleeve 51, and can completely remove the dirt at the water outlet 510 of the bottom wall of the nozzle sleeve 51.

[0058] It is understandable that the shape of the end of the descaling channel 43 facing the bottom wall of the faucet cover 51 is not limited. The shape of the end of the descaling channel 43 facing the bottom wall of the faucet cover 51 can be, for example, a columnar structure, such as a cylindrical structure or a columnar structure with a cross-shaped cross section.

[0059] In other embodiments, one end of the water delivery portion 42 facing the bottom wall of the nozzle sleeve 51 abuts against the bottom wall of the nozzle sleeve 51. The bottom wall of the nozzle sleeve 51 covers one end of the descaling flow channel 43 facing the bottom wall of the nozzle sleeve 51. The water outlet 510 is provided on the bottom wall of the nozzle sleeve 51.

[0060] In this way, the bottom wall of the faucet cover 51 directly covers one end of the descaling channel 43 toward the bottom wall of the faucet cover 51. When the descaling channel 43 sprays water toward the bottom wall of the faucet cover 51, the pressure exerted by the water flow on the bottom wall of the faucet cover 51 is more concentrated, and the deformation energy of the bottom wall of the faucet cover 51 is greater. At the same time, the deformation of the bottom wall of the faucet cover 51 is also more uneven. The structure of the scale attached to the faucet cover 51 becomes looser as the deformation of the faucet cover 51 increases, and it is easier to be washed away by water.

[0061] In an exemplary embodiment, the water outlet direction of one end of the descaling channel 43 toward the bottom wall of the faucet cover 51 is toward the part of the bottom wall of the faucet cover 51 where no water outlet 510 is provided. The water outlet direction of one end of the thin water outlet channel 44 toward the bottom wall of the faucet cover 51 is toward the water outlet 510 on the bottom wall of the faucet cover 51.

[0062] In this way, the descaling flow channel 43 sprays water toward the portion of the bottom wall of the faucet cover 51 where the water outlet 510 is not provided, so that the water can directly impact the bottom wall of the faucet cover 51, and the deformation of the bottom wall of the faucet cover 51 can be larger. The structure of the scale attached to the faucet cover 51 becomes looser as the deformation of the faucet cover 51 increases, and it is easier to be washed away by water. The descaling flow channel 43 sprays water toward the water outlet 510 on the bottom wall of the faucet cover 51, and the water can smoothly enter the water outlet 510 and be output through the water outlet 510, so that the fine water is smoother.

[0063] In an illustrative embodiment, Figure 3 As shown, the thin water outlet channel 44 is arranged on the outer side wall of the water delivery part 42. The thin water outlet channel 44 is configured as a strip groove, which is arranged on the outer side wall of the water delivery part 42 and extends along the axial direction of the water delivery part 42, and the side wall of the nozzle sleeve 51 covers the opening of the strip groove. There are multiple thin water outlet channels 44, for example, there can be 4. Multiple thin water outlet channels 44 are evenly distributed in the circumferential direction of the water delivery part 42.

[0064] Since the diameter of the thin water outlet channel 44 is usually very small, it is difficult to process the thin water outlet channel 44 if it is constructed as a through hole on the water delivery part 42. In the present embodiment, the thin water outlet channel 44 is constructed as a strip groove on the outer wall of the water delivery part 42, and the thin strip groove is easier to process than the thin through hole.

[0065] In an exemplary embodiment, a plurality of water outlets 510 are provided on the faucet cover 51. The number of water outlets 510 of a single faucet cover 51 is the same as the number of thin water outlet channels 44 on a single water delivery portion 42. The plurality of water outlets 510 are respectively aligned with the plurality of thin water outlet channels in the axial direction of the water delivery portion 42.

[0066] In this way, each thin water outlet channel 44 can transport water toward its corresponding water outlet 510, and the water flow output by the thin water outlet channel 44 can be directly output to the outside of the shower through the corresponding water outlet 510, with small resistance to water flow, and the linear water flow sprayed from the water outlet 510 is straight without deflection.

[0067] In an illustrative embodiment, an axial hole 3110 is provided at the bottom of the mounting cavity 31b. The axial hole 3110 may be a through hole. The axial hole 3110 is provided at the central position of the bottom of the mounting cavity 31b. The connecting portion 322 is configured as a rotating shaft, and may be a cylindrical rotating shaft. One end of the connecting portion 322 is connected to the middle of one end of the connecting portion 321 facing the axial hole 3110. The connecting portion 322 passes through the axial hole 3110 at the bottom of the mounting cavity 31b, and one end of the connecting portion 322 facing away from the connecting portion 321 extends out of the axial hole 3110. There is a clearance fit between the connecting portion 322 and the axial hole 3110, and the connecting portion 322 can rotate in the axial hole 3110.

[0068] The switching assembly 3 also includes a turntable 33 and a slider 34. The turntable 33 can be configured as a roughly plate-like structure, and can be a straight strip plate. The plate surface of the turntable 33 is perpendicular to the axial direction of the connecting portion 322. One end of the turntable 33 is connected to the end of the connecting portion 322 that faces away from the connecting portion 321. The turntable 33 and the connecting portion 322 can be snap-fit ​​connected, and the assembly between the turntable 33 and the connecting portion 322 can be more convenient. The turntable 33 is provided with a slideway 331 extending radially along the connecting portion 322. The slideway 331 can be configured as a straight bar hole, and the extension direction of the cross section of the straight bar hole is the radial direction of the connecting portion 322. The slideway 331 can also be configured as a straight bar groove, the opening of the straight bar groove faces the side of the body 311 facing away from the waterway member 31, and the extension direction of the straight bar groove is the radial direction of the connecting portion 322.

[0069] The slider 34 is slidably connected to the waterway member 31. The slider 34 can slide relative to the waterway member 31. The sliding direction of the slider 34 is perpendicular to the axial direction of the connecting portion 322. One end of the slider 34 extends to the side of the turntable 33 facing away from the body 311. The slider 34 is also provided with a protrusion 343 on the side close to the body 311, and the protrusion 343 can be constructed in a cylindrical shape. The protrusion 343 extends into the slideway 331 of the turntable 33. There is a clearance fit between the protrusion 343 and the slideway 331. When the slider 34 slides relative to the waterway member 31, it can drive the turntable 33 to rotate. When the slider 34 slides in one direction relative to the water channel component 31, the protrusion 343 drives the turntable 33 to rotate in one direction. During this process, the protrusion 343 can slide along the slide 331, and the water sealing column 32 rotates in one direction under the drive of the turntable 33; when the slider 34 slides in the other direction relative to the water channel component 31, the protrusion 343 drives the turntable 33 to rotate in the other direction. During this process, the protrusion 343 can slide along the slide 331, and the water sealing column 32 rotates in the other direction under the drive of the turntable 33.

[0070] In this way, the user can drive the turntable 33 to rotate by pushing the slider 34, thereby driving the water sealing column 32 to rotate.

[0071] In an illustrative embodiment, the water channel member 31 further includes a chute 312. The chute 312 is disposed on the body 311. The chute 312 includes a first side plate 3121 and a second side plate 3122, and the first side plate 3121 and the second side plate 3122 are configured as strip plates. The plate surfaces of the first side plate 3121 and the second side plate 3122 are parallel to each other, and the extension directions of the first side plate 3121 and the second side plate 3122 are parallel to each other. The first side plate 3121 and the second side plate 3122 are both connected to the body 311. A strip groove is formed between the first side plate 3121 and the second side plate 3122. The extension direction of the strip groove is perpendicular to the axial direction of the connecting portion 322.

[0072] The slider 34 includes a main body 341 and a rod 342. The main body 341 is configured as a strip-shaped block structure. The main body 341 is at least partially disposed in the strip groove of the slide groove 312. The main body 341 may be disposed at the bottom in the slide groove 312, or the main body 341 may be completely contained in the slide groove 312. There is a clearance fit between the main body 341 and the slide groove 312, and the main body 341 can slide along the slide groove 312. The rod 342 extends from one end of the main body 341 close to the turntable 33 to the side of the turntable 33 facing away from the main body 311. A clearance may be provided between the rod 342 and the turntable 33. The protrusion 343 is disposed at one end of the rod 342 facing away from the main body 341, and is located on the side of the rod 342 close to the turntable 33. In this way, the slider 34 can only slide along the slide groove 312, so that a sliding connection is formed between the slider 34 and the waterway member 31.

[0073] In an illustrative embodiment, Fig.13 As shown, the body 311 includes a cavity 3112 and a tube 3111. One end of the tube 3111 is connected to the cavity 3112. The tube 3111 is configured as a strip structure. The tube 3111 is disposed in the mounting channel of the handle 11 of the housing 1 and extends along the mounting channel. The cavity 3112 is disposed in the mounting cavity of the mounting shell 12. The outline of the cavity 3112 may be disc-shaped.

[0074] The installation cavity 31b is provided at one end of the tube body 3111 close to the cavity 3112. The water inlet channel 31a extends from one end of the tube body 3111 facing away from the cavity 3112 to the installation cavity 31b. The descaling channel 31c and the thin water outlet channel 31d both extend from the cavity 3112 to the installation cavity 31b. The portions of the descaling channel 31c and the thin water outlet channel 31d on the cavity 3112 can be arranged as a roughly annular flow channel, and the thin water outlet channel 31d surrounds the descaling channel 31c.

[0075] The water inlet 2 is arranged in a tubular shape, and is arranged in the installation channel of the handle 11 and extends along the installation channel in the handle 11. One end of the water inlet 2 is connected to the end of the tube 3111 facing away from the cavity 3112. The water inlet channel 31a and the water inlet flow channel 20 are connected to each other at the ends close to each other.

[0076] like Fig.12 As mentioned above, the handle 11 of the housing 1 is also provided with a mounting hole 110. The mounting hole 110 is a through hole. The mounting hole 110 can be configured as a bar hole. The extending direction of the cross section of the mounting hole 110 is the same as the sliding direction of the slider 34. The mounting hole 110 is aligned with the slide groove 312.

[0077] The shower head 100 further includes a push knob 36. The push knob 36 is disposed in the mounting hole 110. There is a clearance fit between the push knob 36 and the mounting hole 110. The push knob 36 is connected to the slider 34. The push knob 36 and the slider 34 may be connected by a snap-fit ​​connection.

[0078] The user can push the push knob 36 to drive the slider 34 to slide, thereby switching the shower head 100 between the descaling water outlet mode and the fine water outlet mode. At the same time, the shower head 100 has a compact structure and is easy to assemble.

[0079] In an illustrative embodiment, Fig. 9 As shown, the switching assembly 3 further includes a sealing ring 35. The sealing ring 35 is disposed in the mounting cavity 31b and sleeved on the connecting portion 322. The sealing ring 35 is sandwiched between the communicating portion 321 and the bottom surface of the mounting cavity 31b. The sealing ring 35 seals the gap between the communicating portion 321 and the bottom surface of the mounting cavity 31b to prevent water leakage at the shaft hole 3110.

[0080] In an exemplary embodiment, the first plate 41 covers one end of the cavity 3112. A descaling cavity 9a is enclosed between the first plate 41 and the cavity 3112. The descaling cavity 9a can be constructed as a gap between the first plate 41 and the cavity 3112.

[0081] A descaling water inlet 31e is provided on one side of the cavity 3112 close to the first plate body 41. A thin water inlet channel 31f is provided on one side of the cavity 3112 close to the first plate body 41. The descaling water inlet 31e is a through hole. The descaling water inlet 31e is provided on the wall surface of the descaling water channel 31c close to the first plate body 41, and the descaling water inlet 31e connects the descaling cavity 9a with the descaling water channel 31c. The thin water inlet channel 31f extends from the wall surface of the thin water outlet water channel 31d close to the first plate body 41 to the water inlet hole 410. The outer wall surface of the thin water inlet channel 31f is sealed with the water inlet hole 410. The two ends of the thin water inlet channel 31f are respectively connected to the thin water outlet cavity 9b and the thin water outlet water channel 31d.

[0082] The descaling channel 43 extends from one end of the water delivery part 42 facing away from the first plate body 41 to the side of the first plate body 41 facing away from the water delivery part 42, and the thin water outlet channel 44 sequentially penetrates the water delivery part 42 and the first plate body 41. The two ends of the descaling channel 43 are respectively connected to the descaling chamber 9a and the water outlet 510 of the nozzle sleeve 51.

[0083] In this way, after the water sealing column 32 rotates to the first descaling water outlet position, water can flow in sequence through the water inlet channel 20 of the water inlet component 2, the water inlet channel 31a of the water channel component 31, the connecting water channel 320 of the water sealing column 32, the descaling water channel 31c of the water channel component 31, the descaling water inlet 31e of the water channel component 31, the descaling chamber 9a, the descaling channel 43 of the flow channel component 4 and the water outlet 510 of the faucet component 5, and be output from the water outlet 510 of the multiple faucet sleeves 51.

[0084] In an illustrative embodiment, Figure 3 , 13As shown, the water inlet hole 410 and the thin water outlet inlet channel 31f are both provided in multiple numbers, and the number is the same. The multiple thin water outlet inlet channels 31f can be arranged in sequence along the thin water outlet channel 31d, for example, the multiple thin water outlet inlet channels 31f are arranged in a ring. The multiple thin water outlet inlet channels 31f extend into the multiple water inlet holes 410 respectively. In this way, the thin water outlet cavity 9b can be connected to the thin water outlet channel 31d through the multiple thin water outlet inlet channels 31f, and the water inlet flow rate of the thin water outlet cavity 9b can be larger.

[0085] In an illustrative embodiment, a plurality of descaling water inlets 31e are provided, and the plurality of descaling water inlets 31e are sequentially arranged along the descaling water channel 31c, and the plurality of descaling water inlets 31e may be arranged in a ring shape.

[0086] A plurality of descaling water inlets 31e connect the descaling water channel 31c and the descaling chamber 9a, and the water inlet channel 20 of the descaling chamber 9a can be larger.

[0087] In an illustrative embodiment, Figure 2 , 5 As shown in Figures 6 and 7, the shower head 100 further includes an inner cover 6, an outer cover 7 and a decorative cover 8. The inner cover 6 and the outer cover 7 are circular plate-like structures. The inner cover 6 is provided with a plurality of first through holes 61. The first through holes 61 penetrate the inner cover 6. The number of the first through holes 61 is the same as the number of the faucet sleeves 51. The inner cover 6 is covered on the second plate body 52, and the plurality of faucet sleeves 51 respectively penetrate the plurality of first through holes 61. The inner cover 6 is connected to the cavity 3112 by screws.

[0088] The outer cover 7 is provided with a plurality of second through holes 71. The second through holes 71 penetrate the outer cover 7. The number of the second through holes 71 is the same as the number of the faucet sleeves 51. The outer cover 7 is covered on the inner cover 6, and the plurality of faucet sleeves 51 penetrate the plurality of second through holes 71 respectively.

[0089] The decoration cover 8 is constructed as an annular structure. The decoration cabinet covers the outer cover 7 and is connected to the installation shell 12. The decoration cover 8 and the installation shell 12 can be snap-fitted.

[0090] In this way, when the descaling flow channel 43 delivers water at a higher water pressure to the water nozzle sleeve 51, since the inner walls of the first through hole 61 and the second through hole 71 are clamped on the side wall of the water nozzle sleeve 51, the inner walls of the first through hole 61 and the second through hole 71 can prevent the side wall of the water nozzle sleeve 51 from expanding radially outward, so that the elastic deformation of the water nozzle sleeve 51 is concentrated on the bottom wall of the water nozzle sleeve 51, which can make the water outlet 510 of the water nozzle sleeve 51 expand larger and the water outlet 510 can be descaled more thoroughly.

[0091] In another exemplary embodiment, a plurality of water outlets 510 are provided on the faucet cover 51. The number of the water outlets 510 is not limited.

[0092] like Fig.18 , 19 As shown, a plurality of descaling channels 43 are provided on each water delivery part 42. The number of water outlets 510 of a single faucet sleeve 51 is the same as the number of descaling channels 43 on a single water delivery part 42, for example, both may be 3. The plurality of descaling channels 43 are each constructed as through holes penetrating the water delivery part 42 along the axial direction of the water delivery part 42. The plurality of descaling channels 43 may be provided near the side wall of the water delivery part 42. The inlets of the plurality of descaling channels 43 on each water delivery part 42 are connected to the pulse assembly 1a, and the outlets of the plurality of descaling channels 43 on each water delivery part 42 are aligned with the plurality of water outlets 510 on the faucet sleeve 51 into which the water delivery part 42 is inserted in the axial direction of the water delivery part 42. The outlets of the plurality of descaling channels 43 on the water delivery part 42 can discharge water toward the plurality of water outlets 510 on the faucet sleeve 51, respectively.

[0093] In this way, Fig. 20 , 21 As shown, the outlet of the descaling flow channel 43 on the water delivery part 42 is arranged in a one-to-one correspondence with the water outlet 510 on the nozzle sleeve 51, and the outlet of the descaling flow channel 43 can discharge water toward the corresponding water outlet 510 on the nozzle sleeve 51. The pulse water flow output from the outlet of the descaling flow channel 43 can not only alternately expand and contract the water outlet 510 so that the dirt on the water outlet 510 can be quickly loosened and peeled off, but also can directly impact the dirt on the water outlet 510, thereby accelerating the dirt shedding speed and enhancing the cleaning power.
